Title: Packaging Machine

Description:
FIELD OF THE INVENTION 
     Technical Field 
     The present disclosure relates to a packaging machine. 
     Background of the Invention 
     PTP packaging machines have been proposed in which a belt-like container film on which pockets are formed is filled with contents and, then, a cover film provided with a printing section is affixed to the container film so as to close the pocket to form a PTP film and, then, the PTP film is punched to manufacture a planarly rectangular PTP sheet (for example, see Japanese Patent Application Publication No. 2015-157648). The PTP packaging machine described in JP 2015-157648 detects, for the punched PTP sheet, an amount of position shift from the ideal position of the pockets, and an amount of position shift from the ideal position of the printing section, and corrects the punching position of the PTP film on the basis of both of these two detected types of amounts of position shift. Additionally, the PTP packaging machine corrects the punching position in the extending direction of the PTP film by changing an angle of rotation per one drive of a film feeding roller to adjust a feed amount of the PTP film. 
     SUMMARY OF THE INVENTION 
     Technical Problem 
     However, there is a possibility of the punching position of the PTP film shifting in the width direction and not only in the extending direction of the PTP film. To address this, in the PTP packaging machine described in JP 2015-157648, the entire sheet punching device that punches the PTP film is moved in the width direction of the PTP film to correct the punching position. However, in this case, an additional driving mechanism is needed to move the entire sheet punching device and, as such, the size of the PTP packaging device tends to increase an amount corresponding to that additional driving mechanism. Moreover, there is a demand to reduce the labor in the process of fabricating packaging packs by using an imaging device to inspect the punched PTP packs. 
     The present disclosure is made with the view of the above situation, and an objective of the present disclosure is to provide a packaging machine whereby it is possible to reduce the size and reduce the labor in the process of fabricating packaging packs. 
     Solution to Problem 
     A packaging machine according to the present disclosure that achieves the objective described above is: 
     a packaging machine for manufacturing a packaging pack by punching, in a state in which a workpiece is stored in a pocket, for storing the workpiece, of a container film on which the pocket is formed, a belt-like pack film obtained by a cover film being adhered to the container film so as to close the pocket, the packaging machine including: 
     a first conveyor that includes a film feeding roller on which the pack film is wound, and that intermittently rotates the film feeding roller one predetermined rotation angle at a time to intermittently feed the pack film one predetermined first reference distance at a time; 
     a punching device that punches the pack film when the pack film intermittently conveyed by the first conveyor is stopped; 
     a first film position changer that includes a guider that is disposed downstream of the first conveyor and that guides the pack film, and that changes a position of the guider in a width direction of the pack film to change a position in the width direction of the pack film in the punching device; 
     a first imager that images the packaging pack punched by the punching device; 
     a position shift amount calculator that calculates, based on a packaging pack image of the packaging pack imaged by the first imager, a position shift amount of a punching position of the pack film by the punching device; 
     a punching position correction amount calculator that calculates, from the position shift amount of the punching position, a punching position correction amount with respect to the punching position; 
     a rotation angle adjuster that adjusts, based on the punching position correction amount, the rotation angle; and 
     a guider position adjuster that adjusts, based on the punching position correction amount, the position of the guider. 
     Advantageous Effects of Invention 
     According to the present disclosure, the first film position changer includes the guider that guides the pack film, and changes the position of the guider in the width direction of the pack film to change the position in the width direction of the pack film in the punching device. Moreover, the punching position correction amount calculator calculates, from the position shift amount of the punching position, the punching position correction amount with respect to the punching position of the pack film, and the guider position adjuster adjusts the position of the guider on the basis of the punching position correction amount. As a result, correction of the punching position in the width direction of the pack film can be carried out without providing a drive mechanism for moving the entire punching device in the width direction of the pack film. Therefore, the size of the packaging machine can be reduced an amount corresponding to the drive mechanism for moving the entire punching device in the width direction of the pack film, that has been made unnecessary. Additionally, since the first imager images the packaging pack punched by the punching device, inspections of the packaging packs can be automated by using the images of the packaging packs captured by the first imager. Therefore, the labor in the process of manufacturing packaging packs can be reduced.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, a packaging machine according to embodiments of the present disclosure is described while referencing the drawings. The packaging machine according to the present embodiment is for manufacturing packaging packs such as blister packs, PTP packs, and the like. In this case, a “packaging pack” includes a container film in which pockets are formed to accommodate workpieces, and a cover film that is affixed to the container film so as to close the pockets. Examples of the workpieces include tube-shaped containers, tablets, food, electronic components, medical devices, and the like. 
     As illustrated in  FIG. 1 , a packaging machine  1  according to the present embodiment includes a raw material film feeding unit  11 , a heating device  29 , a molding device  12 , appearance inspection devices  13 ,  16 ,  31 , a cover film feeding unit  15 , a sealing device  14 , a slit forming/punching unit  17 , and a rotary suction  32 . In this case, the sealing device  14  includes a container film F 2 , and a conveyor  141  that continuously conveys a cover film F 3  and a pack film F 4  downstream. The packaging machine  1  includes a chuck feed  232  that conveys a raw material film F 1  and the container film F 2 , a fixed chuck  231 , a guide roller  251  that guides the pack film F 4 , and a conveyor  281  that intermittently conveys the pack film F 4  downstream. Furthermore, the packaging machine  1  includes a slide guide  293  that restricts position shift of the container film F 2  in a width direction thereof, a tension applier  291  that applies tension to the container film F 2 , a tension adjuster  292 , and a tension applier  252  that applies tension to the pack film F 4 . Additionally, the packaging machine  1  includes a film position changer  26  for correcting position shift of the pack film F 4  in a hereinafter described slit forming device  171  of the slit forming/punching unit  17 , a printing device  27  that prints a mark on the pack film F 4 , and a collection unit (not illustrated in the drawings) that collects scraps discharged from the slit forming/punching unit  17 . In this case, the collection unit has a function of cutting, into strips, the pack film F 4  from which a packaging pack BP has been punched, and collecting the strips. Furthermore, the packaging machine  1  includes a collection unit  34  that collects so-called defective articles of packaging packs such as packaging packs that have shape defects or packaging packs in which the workpiece is not packaged, which are discharged from the rotary suction  32 , and a pack conveying device  33  that includes a belt conveyor  331  that receives packaging packs from the rotary suction  32  and conveys the received packaging packs to another device. 
     Additionally, the packaging machine  1  includes a stage  40  that supports the container film F 2  in a state in which the workpiece can be fed to the pockets of the container film F 2 , and a workpiece feeding device  289  that inserts workpieces placed in a hopper  288  into the pockets of the container film F 2 . In this case, the workpiece feeding device  289  places a workpiece in each pocket of the container film F 2  while the container film F 2  is disposed above the stage  40 . Note that the workpiece feeding device  289  may be omitted. In such a case, it is sufficient that a worker, that carries out the work of feeding the workpiece to the pockets of the container film F 2 , places one workpiece into each pocket while the container film F 2  is disposed above the stage  40 . 
     Furthermore, the packaging machine  1  includes rollers  241 ,  242 ,  253  that guide the pack film F 4  discharged from the sealing device  14 , and a control device  90  that controls the various devices of the packaging machine  1 . Note that, in  FIG. 1 , in order to clarify the drawing, the control device  90  is illustrated outside a packaging machine main body  50  but, in reality, is installed on a back surface side of the packaging machine main body  50 . Moreover, the packaging machine  1  includes the packaging machine main body  50  that accommodates the raw material film feeding unit  11 , the molding device  12 , the appearance inspection devices  13 ,  16 ,  31 , the cover film feeding unit  15 , the sealing device  14 , the slit forming/punching unit  17 , and the like. 
     In the packaging machine  1 , as illustrated by arrow AR 1 , the raw material film F 1  fed from the raw material film feeding unit  11  is conveyed, by the chuck feed  232 , to the heating device  29  and the molding device  12 . Then, as illustrated by arrow AR 2 , the container film F 2  produced in the molding device  12  from the raw material film F 1  is conveyed by the conveyor  141  of the sealing device  14  through above the stage  40  to the appearance inspection device  13  and the sealing device  15 . Meanwhile, as illustrated by arrow AR 3 , the cover film F 3  fed from the cover film feeding unit  15  is conveyed to the sealing device  14  by the conveyor  141  of the sealing device  14 . Then, the sealing device  14  affixes the cover film F 3  to the container film F 2  and, as a result, the pack film F 4  is produced. Additionally, as illustrated by arrow AR 4 , the pack film F 4  produced by the sealing device  14  is conveyed downstream by the conveyor  141 . Meanwhile, as illustrated by arrow AR 5 , the pack film F 4  that is conveyed downstream from the sealing device  14  is intermittently conveyed, by the conveyor  281 , to the slit forming/punching unit  17 . Then, scrap F 5  discharged from the slit forming/punching unit  17  is conveyed to the collection unit. 
     The raw material film feeding unit  11  feeds the belt-like raw material film F 1  that is molded into the container film F 2 . The raw material film feeding unit  11  includes reels  111 ,  112  on which the raw material film F 1  is wound, and an automatic film adhering device  113 . Additionally, the raw material film feeding unit  11  includes rollers  1151 ,  1152 ,  1153  that guide, to the automatic film adhering device  113 , the raw material film F 1  fed from the reels  111 ,  112 , and holding mechanisms  1141 ,  1142  that hold the raw material film F 1 . In this case, the holding mechanisms  1141 ,  1142  respectively have chucks  1141   a ,  1142   a  that hold an end, of the raw material film F 1  fed from the reels  111 ,  112 , that is made to stand-by without being fed to the molding device  12 . Furthermore, the raw material film feeding unit  11  includes a conveyor  1154  that conveys the raw material film F 1 , a film pressing mechanism  116 , a bufferer  117  for causing the feeding downstream of the raw material film F 1  to continue during a period in which the feeding of the raw material film F 1  from the automatic film adhering device  113  is stopped, and a roller  1155  that guides the raw material film F 1  fed from the bufferer  117  to the heating device  29 . The conveyor  1154  includes a roller  1154   a , and a roller driver  1154   b  that drives the roller  1154   a . Examples of the raw material film F 1  include so-called soft films, specifically plastic films such as polyvinyl chloride films that have a thickness of 0.1 mm or less, so-called hard films, specifically plastic films such as polyvinyl chloride films that have a thickness greater than 0.1 mm, metal films such as aluminum films, composite films such as gas barrier films, and the like. 
     When the automatic film adhering device  113  detects that the raw material film F 1  fed from one of the reels  111 ,  112  has run out, the automatic film adhering device  113  adheres a leading end portion of the raw material film F 1  fed from the other of the reels  111 ,  112  to the terminating end portion of the raw material film F 1  fed from the one of the reels  111 ,  112 . The automatic film adhering device  113  stops the feeding of the raw material film F 1  downstream for the period in which the adhering of the raw material film F 1  fed from the other of the reels  111 ,  112  to the raw material film F 1  fed from the one of the reels  111 ,  112  is executed. 
     The film pressing mechanism  116  includes a roller  1161  that contacts the raw material film F 1  from vertically above, a roller  1163 , and an elongated arm  1162 . A first end in the longitudinal direction of the arm  1162  is pivotally supported by a shaft (not illustrated in the drawings) that penetrates the center of roller  1161 , and the roller  1163  is rotatably mounted on a second end of the arm  1162 . Moreover, with the arm  1162 , the second end can swivel with the first end as a base point. The bufferer  117  contacts, from vertically above, a portion, between the rollers  1154   a ,  1155 , of the raw material film F 1  stretched between the rollers  1154   a ,  1155 , and presses the portion vertically downward to apply tension to the raw material film F 1 . The bufferer  117  includes a roller  1171  that contacts the raw material film F 1  from vertically above, and an elongated arm  1172 . The roller  1171  is attached to a first end in the longitudinal direction of the arm  1172 . Additionally, the bufferer  117  includes a supporter  1173  that supports the arm  1172  at a second end in the longitudinal direction of the arm  1172  such that the first end of the arm  1172  can swivel with the second end as a base point. Moreover, the film pressing mechanism  116  includes urging means (not illustrated in the drawing) that urge the second end of the arm  1162  in a direction of pressing against the roller  1154   a , and the raw material film F 1  is pressed against the roller  1154   a  by the roller  1163  that is mounted on the second end of the arm  1162 . Additionally, during the period in which the feeding of the raw material film F 1  from the automatic film adhering device  113  is stopped, the bufferer  117  continues the downstream feeding of the raw material film F 1  by swiveling the first end of the arm  1162  in a direction approaching the automatic film adhering device  113  side. 
     As illustrated in  FIG. 2 , for example, the heating device  29  includes heat transfer plates  2901 ,  2902  that are respectively disposed facing both sides in a thickness direction of the raw material film F 1  and in which heaters (not illustrated in the drawings) are installed, and driving units  2903 ,  2904  that support the heat transfer plates  2901 ,  2902  and that drive the heat transfer plates  2901 ,  2902  in the vertical direction. In one example, the heat transfer plates  2901 ,  2902  are formed from a metal that has high thermal conductivity. The molding device  12  forms a pocket Po 1  in the raw material film F 1  to produce the belt-like container film F 2 . The molding device  12  includes a first mold  123  disposed vertically above the raw material film F 1 , and a second mold  122  disposed vertically below the raw material film F 1 . A plug  122   a  that has an outer shape slightly smaller than an inside shape of the pocket Po 1  to be formed in the raw material film F 1 , and a discharge hole (not illustrated in the drawings) for discharging gas are provided on the second mold  122 . In this case, the plug  122   a  is disposed inside the discharge hole and can protrude outside the discharge hole. Additionally, a heater (not illustrated in the drawings) for suppressing temperature decreases of the raw material film F 1  is installed in the plug  122   a . Note that a configuration is possible in which a heater is not installed in the plug  122   a . Meanwhile, a recess  123   a  corresponding to the outer shape of the pocket Po 1  to be formed in the raw material film F 1  is provided on the first mold  123 . Additionally, the molding device  12  includes a driver  124  that drives the first mold  123  in the vertical direction, a driver  125  that drives the plug  122   a  in the vertical direction, a gas feeder (not illustrated in the drawings) that feeds a gas, and a device main body  121  that supports the drivers  124 ,  125  and the gas feeder. In one example, the gas feeder is connected to a compressor (not illustrated in the drawings) provided in the factory in which the molding device  12  is installed, and feeds a gas to the discharge hole of the second mold  122 . The first mold  123  and the second mold  122  may be appropriately modified in accordance with the depth and the area of the opening portion of the pocket Po 1  of the container film F 2  to be produced. 
     The molding device  12  moves the first mold  123  vertically downward while the raw material film F 1  is disposed in the molding device  12  and, as a result the raw material film F 1  is pressed against the second mold  122  by the first mold  123 . Due to this, the outer periphery of the pocket Po 1  of the raw material film F 1  is clamped by the first mold  123  and the second mold  122 . Then, the molding device  12  causes the plug  122   a  of the first mold  123  to protrude vertically upward a protruding amount corresponding to the depth of the pocket Po 1  to be produced, thereby stretching the raw material film F 1 . Note that the protruding amount of the plug at this time may be appropriately adjusted in accordance with the desired thickness distribution of the pocket Po 1  to be produced. Then, the molding device  12  discharges the gas from the discharge hole while the plug  122   a  is protruding vertically upward, thereby producing the container film F 2  that has the pocket Po 1 . 
     As illustrated in  FIG. 3A , the fixed chuck  231  includes a supporter  231   a  that supports the container film F 2  from vertically below, a clamp  231   b  that, with the supporter  231   a , clamps the container film F 2  from vertically above the container film F 2 , and a driver  231   c  that drives the clamp  231   b  in the vertical direction. The chuck feed  232  is a second conveyor that includes a chuck  2321  that clamps the container film F 2 , and a chuck movement mechanism  2322  that moves the chuck  2321  along a feed direction of the container film F 2 . The chuck  2321  includes a supporter  2321   a  that supports the container film F 2  from vertically below, a clamp  2321   b  that, with the supporter  2321   a , clamps the container film F 2  from vertically above the container film F 2 , and a driver  2321   c  that drives the clamp  2321   b  in the vertical direction. Note that the chuck feed  232  may clamp a portion throughout the entire width direction of the container film F 2 , or may clamp both ends in the width direction of the container film F 2 . Alternatively, the chuck feed  232  may clamp a portion in the width direction of the container film F 2 . 
     Next, the operations of the chuck feed  232  are described. Firstly, when the molding device  12  clamps the raw material film F 1  by the first mold  123  and the second mold  122 , the fixed chuck  231  clamps the container film F 2  as illustrated by arrow AR 21  of  FIG. 3A . At this time, the chuck  2321  of the chuck feed  232  moves upstream of the container film F 2  as illustrated by arrow AR 22  of  FIG. 3A . Next, before the molding device  12  separates the first mold  123  from the second mold  122 , the chuck  2321  of the chuck feed  232  clamps the container film F 2  as illustrated by arrow AR 23  of  FIG. 3B . Next, the fixed chuck  231  releases the clamping of the container film F 2  as illustrated by arrow AR 24  of  FIG. 3B . Then, the chuck movement mechanism  2322  of the chuck feed  232  moves the chuck  2321  downstream as illustrated by arrow AR 25  of  FIG. 3C . As a result, the container film F 2  is conveyed downstream, as illustrated by arrow AR 1  of  FIG. 3C . The fixed chuck  231  again clamps the container film F 2 , and the chuck  2321  of the chuck feed  232  releases the clamping of the container film F 2 . Then, the chuck movement mechanism  2322  moves the chuck  2321  upstream of the container film F 2 , that is, in the direction approaching the fixed chuck  231 . Thereafter, the chuck feed  232  repeats the series of operations described above, thereby intermittently conveying the container film F 2  downstream. 
     The slide guide  293  includes a curved surface  293   a  that slide-contacts the container film F 2 , and slidably supports the container film F 2 . At least the portion of the slide guide  293  including the curved surface  293   a  is formed from a resin material such as polytetrafluoroethylene, polyethylene, polyacetal, or the like, or a metal such as stainless steel. From the perspective of suppressing deformation of the pocket Po 1  of the container film F 2 , a curvature radius of the curved surface  293   a  is preferably longer than at least the length of the pocket Po 1  in the conveyance direction of the container film F 2 . Note that it is preferable that the curvature radius is longer than the length of the container film F 2  in the width direction. The tension applier  291  applies tension to the container film F 2  by contacting the portion, between the slide guide  293  and the tension adjuster  292 , of the container film F 2  stretched between the slide guide  293  and the tension adjuster  292 , and pressing the portion vertically downward. The tension applier  291  includes a roller  2911  that contacts the container film F 2 , and an elongated arm  2912 . The roller  2911  is rotatably attached to a first end in the longitudinal direction of the arm  2912 . Additionally, the tension applier  291  includes a supporter  2913  that supports the arm  2912  at a second end in the longitudinal direction of the arm  2912  such that the first end of the arm  2912  can swivel with the second end as a base point. The tension adjuster  292  includes a roller  2921  on which the container film F 2  is wound, and a powder clutch brake  2922  coupled to the roller  2921  via a driven member shaft (not illustrated in the drawings). The tension adjuster  292  adjusts the rotational torque of the roller  2921  by the powder clutch brake  2922  to adjust the tension applied to the container film F 2  stretched between the roller  2921  and a wheel  141   a  of the sealing device  14 . 
     The appearance inspection device  13  is disposed upstream of the sealing device  14 . The appearance inspection device  13  includes an imager  131  that images the container film F 2 , and a housing  132  that accommodates the imager  131 . The imager  131  is a second imager that sends, the control device  90 , image information obtained by imaging the container film F 2  in which the workpiece stored in the pockets. In this case, a three-dimensional scanning device, a laser scanning device, or the like can be used as the imager  131 . 
     The cover film feeding unit  15  feeds the belt-like cover film F 3 . The cover film feeding unit  15  includes a reel  151  on which the cover film F 3  is wound, rollers  1521 ,  1522 ,  1523  that guide, to the sealing device  14 , the cover film F 3  fed from the reel  151 , a tension adjuster  153 , and a position sensor  154 . Examples of the cover film F 3  include metal films such as aluminum films, composite films such as gas barrier films, and the like. The tension adjuster  153  includes a roller  1531  on which the cover film F 3  is wound, and a powder clutch brake  1532  coupled to the roller  1531  via a driven member shaft (not illustrated in the drawings). The tension adjuster  153  adjusts the rotational torque of the roller  1531  by the powder clutch brake  1532  to adjust the tension applied to the cover film F 3  stretched between the roller  1531  and the roller  1441  of the sealing device  14 .

     Here, a 31  represents the shortest distance, calculated by the packaging pack pocket position calculator  914  described above, between the periphery of the pocket Po 1  closest to the one edge of the packaging pack BP 1  in the longitudinal direction and one of the slits SL 2  formed on both sides, in the longitudinal direction of the packaging pack BP 1 , of that pocket Po 1 .

Furthermore, Δas represents the position shift amount of the slit forming position in the width direction of the pack film F 4 . 
     The spacing between pockets Po 1  adjacent in the width direction of the pack film F 4  may differ from the spacing between the cutters  1714   a  of the slit forming device  171  due to heat shrinkage of the pack film F 4  in the width direction. To solve this, as described above, the position shift amount calculator  916  uses the relational expression of Equation (2) to calculate the position shift amount and, thereby, can accurately calculate the position shift amount of the pack film F 4  in the width direction. 
     Additionally, the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing a regular dimension A 3   c  of the shortest distance between the slit SL 1  formed along the longitudinal direction of the packaging pack BP 1  and the periphery of one of the pockets Po 1  positioned on both sides, in the lateral direction of the packaging pack BP 1 , of that slit SL 1 . Moreover, the position shift amount calculator  916  calculates, as the position shift amount ΔAs of the slit forming position in the conveyance direction of the pack film F 4 , the difference (A 3 −A 3   c ) obtained by subtracting the regular dimension A 3   c  expressed in the acquired information from the shortest distance A 3  calculated by the packaging pack pocket position calculator  914  described above. 
     Furthermore, the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing regular dimensions A 41   c , A 42   c  of the shortest distances between the center of the mark MK 1  in the lateral direction of the packaging pack BP 1  and the periphery of each of two pockets Po 1 .

     Here, A 41  and A 42  respectively represent the shortest distance, calculated by the mark position calculator  915  described above, between the center of the mark MK 1  and the periphery of each of the two pockets Po 1 . Furthermore, Am represents the position shift amount of the mark MK 1  in the conveyance direction of the pack film F 4 . 
     Additionally, the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing a regular dimension a 4   c  of the shortest distance between the center of the mark MK 1  in the longitudinal direction of the packaging pack BP 1  and one edge of the packaging pack BP 1  in the longitudinal direction. Moreover, the position shift amount calculator  916  calculates, as a position shift amount Δam of the mark MK 1  in the width direction of the pack film F 4 , a difference (a 4 −a 4   c ) obtained by subtracting the regular dimension a 4   c  expressed in the acquired information from the shortest distance a 4  calculated by the mark position calculator  915  described above.

Moreover, the position shift amount calculator  916  calculates, as a position shift amount ΔAf of the pocket molding position in the conveyance direction of the container film F 2 , a difference (A 5 −A 5   c ) obtained by subtracting the regular dimension A 5   c  expressed in the acquired information from the shortest distance A 5  calculated by the container film pocket position calculator  913  described above. 
     The determiner  917  acquires information, stored in the determination criteria storage  932 , expressing the correction execution threshold for each of the position shift amounts ΔAc and Δac of the punching position, the position shift amounts ΔAs and Δas of the slit forming position, the position shift amounts Am and am of the mark position, and the position shift amount ΔAf of the pocket molding position. When one of the absolute values of the position shift amounts ΔAc and Δac of the punching position, the position shift amounts ΔAs and Δas of the slit forming position, the position shift amounts Am and am of the mark position, or the position shift amount ΔAf of the pocket molding position exceeds the correction execution threshold, the determiner  917  determines that correction of the punching position, the slit forming position, the mark position, or the pocket molding position is needed. 
     The determiner  917  acquires the pass/fail determination criteria information described above that is stored in the determination criteria storage  932 . Then, the determiner  917  determines, on the basis of the pass/fail determination criteria information and the image information of the pack film F 4  acquired from the imager  161  of the appearance inspection device  16 , the pass/fail of portions corresponding to each packaging pack BP 1  of the pack film F 4 . Then, the determiner  917  outputs, on the basis of determination results and to the rotary suction  32 , control information for sorting out the defective articles of the packaging pack BP 1 . 
     When the determiner  917  determines that the position shift amounts ΔAc and/or Δac of the punching position exceed the correction execution thresholds, the punching position correction amount calculator  919  calculates the punching position correction amount in the conveyance direction or the width direction of the pack film F 4  with respect to the punching position of the pack film F 4 . The punching position correction amount corresponds to an amount of correction of the punching position in the direction in which the absolute values of the position shift amounts ΔAc and/or Δac of the punching position decrease. 
     When the determiner  917  determines that the position shift amounts ΔAs, Δas of the slit forming position exceed the correction execution thresholds, the slit position correction amount calculator  920  calculates the slit forming position correction amount in the conveyance direction or the width direction of the pack film F 4  with respect to the slit forming position of the pack film F 4 . The slit forming position correction amount corresponds to an amount of correction of the slit forming position in the direction in which the absolute values of the position shift amounts ΔAs, Δas of the slit forming position decrease. Additionally, when the conveyance controller  923  (described later) changes the rotation angle for when intermittently rotating the film feeding roller  2811  one predetermined rotation angle at a time, the slit position correction amount calculator  920  calculates a slit forming position correction amount in the conveyance direction of the pack film F 4  resulting from this change of the rotation angle.

     When the determiner  917  determines that the position shift amounts ΔAm, Δam of the mark position where the mark MK 1  is formed on the pack film F 4  exceed the correction execution thresholds, the mark position correction amount calculator  921  calculates the mark position correction amount with respect to the mark position. The mark position correction amount corresponds to an amount of correction of the mark position in the direction in which the absolute values of the position shift amounts ΔAm, Δam of the mark position decrease. Additionally, when the conveyance controller  923  (described later) changes the rotation angle of the film feeding roller  2811 , the mark position correction amount calculator  921  calculates a mark position correction amount in the conveyance direction of the pack film F 4  resulting from this change of the rotation angle. This mark position correction amount corresponds to an amount of correction of the mark position in the direction in which the absolute value of the position shift amount, of the mark position in the conveyance direction of the pack film F 4 , resulting from the change of the rotation angle decreases. 
     When the determiner  917  determines that the position shift amount ΔAf of the pocket molding position of the container film F 2  exceeds the correction execution threshold, the pocket molding position correction amount calculator  918  calculates the pocket molding position correction amount. The pocket molding position correction amount corresponds to an amount of correction of the pocket molding position in the direction in which the absolute value of the position shift amount ΔAf of the pocket molding position decreases. 
     The conveyance controller  923  functions as a rotation angle adjuster that adjusts, on the basis of the punching position correction amount calculated by the punching position correction amount calculator  919 , the rotation angle for when the conveyor  281  intermittently rotates the film feeding roller  2811  one predetermined rotation angle at a time. When the determiner  917  determines that the absolute value of the position shift amount Δac of the punching position in the conveyance direction of the pack film F 4  exceeds the correction execution threshold, the conveyance controller  923  generates and outputs, to the output interface  905 , control information for adjusting the rotation angle. This control information is for adjusting the rotation angle so as to shift the punching position the punching position correction amount, calculated by the punching position correction amount calculator  919 , in the conveyance direction of the pack film F 4 . Then, the output interface  905  generates and outputs, to the roller driver  2812 , a control signal corresponding to the control information for adjusting the rotation angle input from the conveyance controller  923 . 
     The film guide position controller  924  functions as a guider position adjuster that adjusts, on the basis of the punching position correction amount calculated by the punching position correction amount calculator  919 , the position of the film guide  2831 .

This control information is for moving the film guide  2831  so as to shift the punching position the punching position correction amount, calculated by the punching position correction amount calculator  919 , in the width direction of the pack film F 4 . Then, the output interface  905  generates and outputs, to the guide driver  2832 , a control signal corresponding to the control information for moving the film guide  2831  input from the film guide position controller  924 . 
     The slit position controller  926  functions as a guide roller position adjuster that adjusts, on the basis of the slit forming position correction amount calculated by the slit position correction amount calculator  920 , the position of the guide roller  261 . When the determiner  917  determines that the absolute values of the position shift amounts ΔAs, Δas of the slit forming position in the conveyance direction or the width direction of the pack film F 4  exceed the correction execution thresholds, the slit position controller  926  generates and outputs, to the output interface  905 , control information for adjusting the position of the guide roller  261 . This control information is for moving the guide roller  261  so as to shift the slit forming position the slit position correction amount, calculated by the slit position correction amount calculator  920 , in the conveyance direction or the width direction of the pack film F 4 . Then, the output interface  905  generates and outputs, to the guide driver  264 , a control signal corresponding to the control information for moving the guide roller  261  input from the slit position controller  926 . Additionally, when the conveyance controller  923  changes the rotation angle described above, the slit position controller  926  generates and outputs, to the output interface  905 , control information for moving the guide roller  261  the slit position correction amount calculated by the slit position correction amount calculator  920  described above. 
     The printing controller  925  functions as a print head position adjuster that adjusts, on the basis of the mark position correction amount calculated by the mark position correction amount calculator  921 , the position of the print head  272  of the printing device  27 . When the determiner  917  determines that the absolute values of the position shift amounts ΔAm, Δam of the mark position in the conveyance direction or the width direction of the pack film F 4  exceed the correction execution thresholds, the printing controller  925  generates and outputs, to the output interface  905 , control information for adjusting the position of the print head  272 . This control information is for moving the print head  272  so as to shift the mark position the mark position correction amount, calculated by the mark position correction amount calculator  921 , in the conveyance direction or the width direction of the pack film F 4 . Then, the output interface  905  generates and outputs, to the supporter driver  275  of the printing device  27 , a control signal corresponding to the control information for moving the print head  272  input from the printing controller  925 . Additionally, when the conveyance controller  923  changes the rotation angle described above, the slit position controller  926  generates and outputs, to the output interface  905 , control information for adjusting the position of the guide roller  261  so that the position of the guide roller  261  reduces the shift amount of the punching position in the conveyance direction of the pack film F 4  resulting from the change of the rotation angle. Additionally, when the conveyance controller  923  changes the rotation angle described above, the printing controller  925  generates and outputs, to the output interface  905 , control information for moving the print head  272  the mark position correction amount calculated by the mark position correction amount calculator  921  described above. 
     The chuck feed controller  922  functions as a feed amount adjuster that adjusts, on the basis of the pocket molding position correction amount calculated by the pocket molding position correction amount calculator  918 , a second reference distance for when the chuck feed  232  intermittently conveys the container film F 2  downstream one predetermined second reference distance at a time. When the determiner  917  determines that the absolute value of the position shift amount ΔAf of the pocket molding position exceeds the correction execution threshold, the chuck feed controller  922  generates and outputs, to the output interface  905 , control information for adjusting the second reference distance. This control information is for increasing/decreasing the second reference distance the pocket molding position correction amount calculated by the pocket molding position correction amount calculator  918 . Then, the output interface  905  generates and outputs, to the chuck feed  232 , a control signal corresponding to the control information for adjusting the second reference distance input from the chuck feed controller  922 . 
     Next, position correction processing executed by the control device  90  according to the present embodiment is described while referencing  FIGS. 11 and 12 . In one example, this position correction processing starts when the power to the control device  90  is turned ON. Firstly, as illustrated in  FIG. 11 , a determination is made of whether the packaging pack image acquirer  912  acquires, from the imager  311  of the appearance inspection device  31 , image information expressing a packaging pack image (step S 101 ). When a determination is made that the image information is not acquired by the packaging pack image acquirer  912  (step S 101 ; No), the processing of step S 122  (described later) is executed. However, it is assumed that the packaging pack image acquirer  912  determines that the image information is acquired (step S 101 ; Yes). In this case, the packaging pack pocket position calculator  914  calculates, on the basis of the packaging pack image, a distance that reflects the relative position of the pocket Po 1  with respect to the packaging pack BP 1  (step S 102 ). Here, the packaging pack pocket position calculator  914  calculates the shortest distances A 1 , A 2 , a 1 , a 2  between the edges of the packaging pack BP 1  and the peripheries of the pockets Po 1 . 
     Next, the packaging pack pocket position calculator  914  calculates, on the basis of the packaging pack image, distances that reflect the relative positions of the pockets Po 1  with respect to the slits SL 1 , SL 2  formed in the packaging pack BP 1  (step S 103 ). Here, the packaging pack pocket position calculator  914  calculates the shortest distances A 3 , a 31 , a 32  between the slits SL 1 , SL 2  formed in the packaging pack BP 1  and the peripheries of the pockets Po 1 . 
     Next, the mark position calculator  915  calculates, on the basis of the packaging pack image, a distance that reflects the relative position of the mark, printed on the packaging pack BP 1 , with respect to the packaging pack BP 1  (step S 104 ). Here, the mark position calculator  915  calculates the shortest distances A 41 , A 42  between the center of the mark MK 1  and the peripheries of the pockets Po 1 , and the shortest distance a 4  between the center of the mark MK 1  and the edge of the packaging pack BP 1 . 
     Thereafter, the position shift amount calculator  916  calculates the position shift amounts ΔAc, Δac of the punching position from the calculated distances that reflect the relative position of the pocket Po 1  with respect to the packaging pack BP 1  (step S 105 ). 
     Next, the determiner  917  determines, on the basis of the position shift amounts ΔAc, Δac of the punching position, whether correction of the punching position is needed (step S 106 ). Here, when at least one of the absolute values |ΔAc|, |Δac| of the position shift amounts ΔAc, Δac of the punching position exceeds the correction execution threshold described above, the determiner  917  determines that correction of the punching position is needed. When the determiner  917  determines that correction of the punching position is not needed (step S 106 ; No), the processing of step S 114  (described later) is executed. 
     However, it is assumed that the determiner  917  determines that correction of the punching position is needed (step S 106 ; Yes). In this case, the punching position correction amount calculator  919  determines whether the absolute value |ΔAc| of the position shift amount ΔAc of the punching position in the conveyance direction of the pack film F 4  exceeds a correction execution threshold ΔActh (step S 107 ). When the punching position correction amount calculator  919  determines that the absolute value |ΔAc| of the position shift amount ΔAc of the punching position in the conveyance direction of the pack film F 4  is less than or equal to the correction execution threshold ΔActh (step S 107 ; No), the processing of step S 111  (described later) is executed. Meanwhile, when the punching position correction amount calculator  919  determines that the absolute value |ΔAc| of the position shift amount ΔAc of the punching position in the conveyance direction of the pack film F 4  exceeds the correction execution threshold ΔActh (step S 107 ; Yes), the punching position correction amount calculator  919  calculates the punching position correction amount in the conveyance direction of the pack film F 4  (step S 108 ). Then, the slit position correction amount calculator  920  calculates the slit forming position correction amount in the conveyance direction of the pack film F 4  resulting from the change of the rotation angle of the conveyor  281 , and the mark position correction amount calculator  921  calculates the mark position correction amount in the conveyance direction of the pack film F 4  resulting from the change of the rotation angle of the conveyor  281  (step S 109 ). 
     Thereafter, the conveyance controller  923  generates and outputs, to the output interface  905 , the control information for adjusting the rotation angle of the conveyor  281  on the basis of the punching position correction amount in the conveyance direction of the pack film F 4  calculated by the punching position correction amount calculator  919  (step S 110 ). At this time, the slit position controller  926  generates and outputs, to the output interface  905 , the control information for moving the guide roller  261  the slit position correction amount calculated by the slit position correction amount calculator  920  described above. Additionally, the printing controller  925  generates and outputs, to the output interface  905 , the control information for moving the print head  272  the mark position correction amount calculated by the mark position correction amount calculator  921  described above. 
     Next, the punching position correction amount calculator  919  determines whether the absolute value |Δac| of the position shift amount Δac of the punching position in the width direction of the pack film F 4  exceeds a correction execution threshold Δacth (step S 111 ). When the punching position correction amount calculator  919  determines that the absolute value |Δac| of the position shift amount Δac of the punching position in the width direction of the pack film F 4  is less than or equal to the correction execution threshold Δacth (step S 111 ; No) the processing of step S 114  (described later) is executed. Meanwhile, when the punching position correction amount calculator  919  determines that the absolute value |Δac| of the position shift amount Δac of the punching position in the width direction of the pack film F 4  exceeds the correction execution threshold Δacth (step S 111 ; Yes), the punching position correction amount calculator  919  calculates the punching position correction amount in the width direction of the pack film F 4  (step S 112 ). Then, the film guide position controller  924  generates and outputs, to the output interface  905 , the control information for adjusting the position of the film guide  2831  on the basis of the punching position correction amount in the width direction of the pack film F 4  calculated by the punching position correction amount calculator  919  (step S 113 ). 
     Thereafter, the position shift amount calculator  916  calculates the position shift amounts ΔAs, Δas of the slit forming positions from the calculated distances that reflect the relative position of the pocket Po 1  with respect to the slits SL 1 , SL 2  (step S 114 ). 
     Next, as illustrated in  FIG. 12 , the determiner  917  determines, on the basis of the position shift amounts ΔAs, Δas of the slit forming position, whether correction of the slit forming position is needed (step S 115 ). Here, when any of the absolute values of the position shift amounts ΔAs, Δas of the slit forming position exceed the correction execution thresholds described above, the determiner  917  determines that correction of the slit forming position is needed. When the determiner  917  determines that correction of slit forming position is not needed (step S 115 ; No), the processing of step S 118  (described later) is executed. 
     However, it is assumed that the determiner  917  determines that correction of the slit forming position is needed (step S 115 ; Yes). In this case, the slit position correction amount calculator  920  calculates the slit forming position correction amount, in the conveyance direction or the width direction of the pack film F 4 , with respect to the slit forming position of the pack film F 4  (step S 116 ). Then, the slit position controller  926  generates and outputs, to the output interface  905 , the control information for adjusting the position of the guide roller  261  on the basis of the slit forming position correction amount calculated by the slit position correction amount calculator  920  (step S 117 ). 
     Thereafter, the position shift amount calculator  916  calculates, on the basis of the packaging pack image described above, the mark position shift amount of the mark MK 1  described above (step S 118 ). 
     Next, as illustrated in  FIG. 12 , the determiner  917  determines, on the basis of the position shift amounts ΔAm, Δam of the mark MK 1 , whether correction of the mark position is needed (step S 119 ). Here, when at least one of the absolute values |ΔAm|, |Δam| of the position shift amounts ΔAm, Δam of the mark position exceeds the correction execution threshold described above, the determiner  917  determines that correction of the mark position is needed. When the determiner  917  determines that correction of slit forming position is not needed (step S 119 ; No), the processing of step S 122  (described later) is executed. 
     However, it is assumed that the determiner  917  determines that correction of the mark position is needed (step S 119 ; Yes). In this case, the mark position correction amount calculator  921  calculates the mark position correction amount, in the conveyance direction and the width direction of the pack film F 4 , with respect to the mark position (step S 120 ). Then, the printing controller  925  generates and outputs, to the output interface  905 , the control information for adjusting the position of the print head  272  on the basis of the mark position correction amount calculated by the mark position correction amount calculator  921  (step S 121 ). 
     Thereafter, a determination is made of whether the container film image acquirer  911  acquires, from the imager  131  of the appearance inspection device  13 , image information expressing a container film image (step S 122 ). When a determination is made that that the image information is not acquired by the container film image acquirer  911  (step S 122 ; No), the processing of step S 101  is executed again. However, it is assumed that the container film image acquirer  911  acquires the image information (step S 101 ; Yes). In this case, the position shift amount calculator  916  calculates the position shift amount ΔAf of the pocket molding position in the conveyance direction of the container film F 2  described above (step S 123 ). 
     Next, the determiner  917  determines, on the basis of the position shift amount ΔAf of the pocket molding position in the container film F 2 , whether correction of the pocket molding position is needed (step S 124 ). Here, when the absolute value |ΔAf| of the position shift amount ΔAf of the pocket molding position exceeds the correction execution threshold described above, the determiner  917  determines that correction of the pocket molding position is needed. When the determiner  917  determines that correction of the pocket molding position is not needed (step S 124 ; No), the processing of step S 101  is executed again. 
     However, it is assumed that the determiner  917  determines that correction of the pocket molding position is needed (step S 124 ; Yes). In this case, the pocket molding position correction amount calculator  918  calculates the pocket molding position shift amount (step S 125 ). Then, the chuck feed controller  922  generates and outputs, to the output interface  905 , the control information for adjusting, on the basis of the pocket molding position correction amount calculated by the pocket molding position correction amount calculator  918 , the second reference distance for when the chuck feed  232  intermittently conveys the container film F 2  downstream one predetermined second reference distance at a time (step S 126 ). Then, the processing of step S 101  is executed again. 
     As described above, with the packaging machine  1  according to the present embodiment, the film position changer  283  includes the film guide  2831  that guides the pack film F 4  and changes the position of the film guide  2831  in the width direction, that is, the X-axis direction of the pack film F 4  to change the position in the width direction of the pack film F 4  in the punching device  173 . Moreover, the punching position correction amount calculator  919  calculates, from the pocket position shift amount described above, the punching position correction amount with respect to the punching position of the pack film F 4 . Additionally, the film guide position controller  924  adjusts the position of the film guide  2831  on the basis of the punching position correction amount. As a result, correction of the punching position in the width direction of the pack film F 4  can be carried out without providing a drive mechanism for moving the entire punching device  173  in the width direction of the pack film F 4 . Therefore, the size of the packaging machine  1  can be reduced an amount corresponding to the drive mechanism for moving the entire punching device  173  in the width direction of the pack film F 4 , that has been made unnecessary. Additionally, the quality control of the packaging pack BP 1  fabricated by the packaging machine  1  is facilitated and, due to this, benefits such as an improvement in the quality of the packaging pack BP 1  and a reduction of labor in the process of fabricating the packaging pack BP 1  are realized. 
     The relative position in the conveyance direction or the relative position in the width direction of the pack film F 4  may shift due to variations in the shrinking performance of the pack film F 4  and variations in the mechanical performance of the packaging machine  1 . In such cases, there is a possibility of large amounts of defective articles of the packaging pack BP 1  being produced, operational defects occurring in the sealing device  14 , the slit forming device  171 , the printing device  27 , and/or the punching device  173 , and the like. To solve this, with the packaging machine  1  according to the present embodiment, the feed amounts of the container film F 2  and the pack film F 4  in the sealing device  14 , the slit forming device  171 , the printing device  27 , and the punching device  173  are configured to be constant on the basis of the image information obtained by imaging the packaging pack BP 1  and the image information obtained by imaging the container film F 2 . Therefore, the defective articles of the packaging pack BP 1  resulting from position shifts in the conveyance direction or the width direction of the pack film F 4  can be reduced, and the occurrence of operational defects in the sealing device  14 , the slit forming device  171 , the printing device  27 , and the punching device  173  can be suppressed. 
     With the packaging machine  1  according to the present embodiment, the film position changer  26  moves the guide roller  261  in the conveyance direction of the pack film F 4  or in the width direction of the pack film F 4  to change the position of the pack film F 4  in the slit forming device  171 . Additionally, the position shift amount calculator  916  calculates the slit position shift amount of the slits SL 1 , SL 2  on the basis of the packaging pack image, and the slit position correction amount calculator  920  calculates the slit position correction amount with respect to the slit position at which the slits SL 1 , SL 2  are to be formed. Moreover, the guide driver  264  adjusts the position of the guide roller  261  on the basis of the calculated slit position correction amount. As a result, correction of the slit position in the conveyance direction or the width direction of the pack film F 4  can be carried out without providing a drive mechanism for moving the entire slit forming device  171  in the conveyance direction or the width direction of the pack film F 4 . Therefore, the size of the packaging machine  1  can be reduced an amount corresponding to the drive mechanism for moving the entire slit forming device  171  in the conveyance direction or the width direction of the pack film F 4 , that has been made unnecessary. 
     Furthermore, with the packaging machine  1  according to the present embodiment, the position shift amount calculator  916  calculates the mark position shift amount of the mark MK 1  on the basis of the packaging pack image, and the mark position correction amount calculator  921  calculates the mark position correction amount with respect to the mark position from the calculated mark position shift amount. Moreover, the printing controller  925  adjusts, on the basis of the calculated mark position correction amount, the position of the print head  272  of the printing device  27 . As a result, the occurrence of position shifts of the mark MK 1  can be suppressed in configurations in which the mark MK 1  is printed on the pack film F 4  in the packaging machine  1 . 
     When the conveyance controller  923  changes the rotation angle of the conveyor  281 , the film position changer  26  according to the present embodiment generates and outputs the control information for adjusting the position of the guide roller  261  so as to reduce the shift amount of the slit forming position in the conveyance direction of the pack film F 4  resulting from the change of the rotation angle. Additionally, as described above, when the rotation angle of the conveyor  281  is changed as described above, the printing controller  925  generates and outputs the control information for adjusting the position of the print head  272  so as to reduce the shift amount of the mark position in the conveyance direction of the pack film F 4  resulting from the change of the rotation angle. As a result, when the rotation angle of the conveyor  281  is changed as described above, the occurrence of position shifts of the slit forming position and the mark position in the conveyance direction of the pack film F 4  resulting from the change in the rotation angle can be suppressed. 
     Furthermore, the packaging machine  1  according to the present embodiment includes the imager  131  that is disposed upstream of the sealing device  14  and that images the container film F 2 , and the chuck feed  232  that is disposed downstream of the molding device  12 , clamps the container film F 2  from the thickness direction, and intermittently conveys the container film F 2  downstream one second reference distance at a time. Additionally, the position shift amount calculator  916  calculates the pocket molding position shift amount of the pocket molding position on the basis of the container film image of the container film F 2  imaged by the imager  131 , and the pocket molding position correction amount calculator  918  calculates the pocket molding position correction amount from the pocket molding position shift amount. Moreover, the chuck feed controller  922  adjusts the second reference distance on the basis of the pocket molding position correction amount. As a result, occurrences of position shifts of the pocket molding position in the conveyance direction of the container film F 2  can be suppressed. 
     The packaging machine  1  according to the present embodiment includes the rotary suction  32  described above. As such, it is possible to smoothly perform operations from receiving of the packaging pack BP 1  from the punching device  173  to imaging of the packaging pack BP 1  by the imager  311  of the appearance inspection device  31 . Therefore, the manufacturing efficiency of the packaging pack BP 1  can be improved. 
     An embodiment of the present disclosure is described above, but the present disclosure is not limited to the configuration described in this embodiment. For example, as illustrated in  FIG. 13 , it is assumed that two slits SL 21 , SL 22  are formed in the packaging pack BP 2 , along the longitudinal direction of the packaging pack BP 2 . In this case, a configuration is possible in which the packaging pack pocket position calculator  914  calculates shortest distances A 61 , A 62 , in the lateral direction of the packaging pack BP 2 , between each of the two slits SL 21 , SL 22  and the periphery of the pocket Po 1 . In this case, the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing regular dimensions A 61   c , A 62   c  of the shortest distances, in the lateral direction of the packaging pack BP 1 , between each of the two slits SL 21 , SL 22  and the periphery of the pocket Po 1 . Moreover, a configuration is possible in which the position shift amount calculator  916  calculates, on the basis of the relational expression of Equation (4) below, a position shift amount of the slit forming position the conveyance direction of the pack film F 4 .

     Here, A 61  and A 62  respectively represent the shortest distance in the lateral direction of the packaging pack BP 2 , calculated by the packaging pack pocket position calculator  914  described above, between each of the two slits SL 21 , SL 22  and the periphery of the pocket Po 1 . Additionally, ΔAs represents the position shift amount of the two slits SL 21 , SL 22  in the conveyance direction of the pack film F 4 . 
     In the embodiment, as, for example, illustrated in  FIG. 14 , a configuration is possible in which the packaging pack pocket position calculator  914  calculates a distance B 1  between one edge of the packaging pack BP 1  in the lateral direction and the center of the pocket Po 1  closest to that one edge, and a distance B 2  between the other edge of the packaging pack BP 1  in the lateral direction and the center of the pocket Po 1  closest to that other edge. Additionally, a configuration is possible in which the packaging pack pocket position calculator  914  calculates a distance b 1  between one edge of the packaging pack BP 1  in the longitudinal direction and the center of the pocket Po 1  closest to that one edge, and a distance b 2  between the other edge of the packaging pack BP 1  in the longitudinal direction and the center of the pocket Po 1  closest to that other edge. 
     Additionally, in the embodiment, a configuration is possible in which the packaging pack pocket position calculator  914  calculate a distance B 3  between the slit SL 1  formed along the longitudinal direction of the packaging pack BP 1  and the center of one of the pockets Po 1  positioned on both sides, in the lateral direction of the packaging pack BP 1 , of that slit SL 1 . Moreover, a configuration is possible in which the packaging pack pocket position calculator  914  calculates distances b 31 , b 32  between the center of the pocket Po 1  closest to the one edge of the packaging pack BP 1  in the longitudinal direction and the slits SL 2  formed on both sides, in the longitudinal direction of the packaging pack BP 1 , of that pocket Po 1 . Furthermore, a configuration is possible in which the packaging pack pocket position calculator  914  calculates a distance b 33  between the center of the pocket Po 1  closest to the other edge of the packaging pack BP 1  in the longitudinal direction and the slit SL 2  formed on the other side, in the longitudinal direction of the packaging pack BP 1 , of that pocket Po 1 . 
     Furthermore, in the embodiment, as, for example, illustrated in  FIG. 14 , a configuration is possible in which the mark position calculator  915  calculates distances B 41 , B 42  between the center of the mark MK 1  in the lateral direction of the packaging pack BP 1  and the center of each of two pockets Po 1 . 
     In the embodiment, an example is described in which the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing the regular dimensions a 31   c , a 33   c  of the shortest distances between the peripheries of the pockets Po 1  and the slits SL 2  and, on the basis of the relational expression of Equation (2) described above, calculates the position shift amount of the punching position in the width direction of the pack film F 4 . However, the embodiment is not limited thereto and, for example, a configuration is possible in which the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing the regular dimension a 31   c  (a 32   c , a 33   c ) of the shortest distance between the periphery of the pocket Po 1  and the slit SL 2 , and calculate, as the position shift amount of the punching position in the width direction of the pack film F 4 , a difference obtained by subtracting the regular dimension a 31   c  (a 32   c , a 33   c ) from the shortest distance a 31  (a 32 , a 33 ), calculated from the packaging pack image, between the periphery of the pocket Po 1  and the slit SL 2 . 
     Alternatively, a configuration is possible in which the position shift amount calculator  916  acquires information, stored in the regular dimension storage  931 , expressing the regular dimensions a 31   c , a 32   c  of the shortest distances between the periphery of the pocket Po 1  in the longitudinal direction of the packaging pack BP 1  and the slits SL 2  formed on both sides, in the longitudinal direction of the packaging pack BP 1 , of that pocket Po 1 , and, on the basis of the relational expression of Equation (5) below, calculates the position shift amount of the punching position in the width direction of the pack film F 4 .

     Here, a 31  and a 32  represent the shortest distances, calculated by the packaging pack pocket position calculator  914  described above, between the periphery of the pocket Po 1  and the slits SL 2  formed on both sides, in the longitudinal direction of the packaging pack BP 1 , of that pocket Po 1  (see  FIG. 10 ). Additionally, Δas represents the position shift amount of the slit forming position in the width direction of the pack film F 4 . 
     In the embodiment, an example is described in which the printing device  27  stamps the mark on the pack film F 4  by pressing the print head  272  against the die unit  273  while the pack film F 4  is interposed between the print head  272  and the die unit  273 . However, the configuration of the printing device  27  is not limited thereto and, for example, a configuration is possible in which a laser marker device is implemented. Additionally, when there is no need to provide a mark on the packaging pack BP 1 , the printing device  27  may be omitted. In this case, it is sufficient to provide the control device  90  with a configuration in which the mark position calculator  915 , the mark position correction amount calculator  921 , and the printing controller  925  are omitted. 
     In the embodiment, an example is described in which the second reference distance, for when the chuck feed  232  intermittently conveys the container film F 2  downstream one predetermined second reference distance at a time, is adjusted on the basis of the pocket molding position correction amount calculated by the pocket molding position correction amount calculator  918 . However, the embodiment is not limited thereto and, for example, a configuration is possible in which the control device  90  controls the powder clutch brake  2922  of the tension adjuster  292  on the basis of the pocket molding position correction amount calculated by the pocket molding position correction amount calculator  918  to adjust the rotational torque of the roller  2921 . 
     In the embodiment, as, for example, illustrated in  FIG. 15A , a configuration is possible in which the packaging machine further includes an edge sensor  20031  disposed downstream of the molding device  12 , and a film position changer  21155  disposed upstream of the heating device  29 . In this case, the edge sensor  20031  includes two sets of laser sources  20031   a  and light receivers  20031   b  disposed facing each other at both edges in the width direction of the container film F 2 , and detects the positions of both edges in the width direction of the container film F 2 . Specifically, when, for example, laser light emitted from the laser sources  20031   a  is blocked by one of both edges of the container film F 2  and does not reach the light receiver  20031   b , the edge sensor  20031  outputs, to the control device, an identification signal of the light receiver  20031   b , of the two light receivers  20031   b , that does not receive the laser light. Note that, the edge sensor may include one laser source and light receiver disposed facing each other at only one edge in the width direction of the container film F 2 , and detect the position of one edge in the width direction of the container film F 2 . 
     The film position changer  21155  is, as illustrated in  FIG. 15B , for example, a third film position changer that includes a guide roller  21155   a  that guides the raw material film F 1  to be fed to the molding device  12 , a roller supporter  21155   b  that rotatably supports the guide roller  21155   a , and a guide driver  21155   e . The guide roller  21155   a  is a second guide roller that includes a cylindrical roller main body  21155   d , and two disc-like guiders  21155   c  provided at both ends in the cylinder-axis direction of the roller main body  21155   d . The guide driver  21155   e  moves, via the roller supporter  21155   b , the guide roller  21155   a  in the width direction of the raw material film F 1 , that is, in the X-axis direction (see arrow AR 201  of  FIG. 15B ). In one example, as illustrated by the dot-dash line of  FIG. 15B , the guide driver  21155   e  shifts the position of the guide roller  21155   a  to the +X direction side to change the position in the X-axis direction of the raw material film F 1  in the molding device  12  to a position shifted to the +X direction side. 
     The control device according to the present modified example has the same configuration as the control device  90  described in Embodiment 1 and, in addition to the features of the control device  90 , also includes a raw material film position correction amount calculator and a roller position adjuster. The raw material film position correction amount calculator calculates, on the basis of the positions of both ends of the container film F 2  detected by the edge sensor  20031 , a raw material film position correction amount of the raw material film F 1  in the width direction. Specifically, when the identification signal of the light receiver  20031   b  that does not receive the laser light is received from the edge sensor  20031 , the raw material film position correction amount calculator calculates, from the distance between the two light receivers  20031   b , a raw material film position correction amount for shifting the raw material film F 1  from the light receiver  20031   b  corresponding to the identification signal toward the other light receiver  20031   b  side, a distance corresponding to ½ the difference from the width of the raw material film F 1 . 
     The roller position adjuster is a second guide roller position adjuster that adjusts, on the basis of the raw material film position correction amount, the position of the guide roller  21155   a . The roller position adjuster generates and outputs, to the output interface of the control device, control information for adjusting the position of the guide roller  21155   a . Then, the output interface generates and outputs, to the guide driver  21155   e , a control signal corresponding to the control information input from the roller position adjuster. 
     According to the present configuration, the need to manually adjust the position of the raw material film F 1  in the width direction is eliminated and, as such, the labor in the process of manufacturing the packaging pack BP 1  can be reduced. 
     In the embodiment, as illustrated in  FIG. 16A , a configuration is possible in which the cover film F 3  includes an adhesion region AA 31  that is caused to adhere to the container film F 2 , and non-adhesion regions AA 32  that are disposed at positions facing the pockets Po 1  in the container film F 2  and that are not caused to adhere to the container film F 2 . Moreover, as illustrated in  FIG. 16B , a configuration is possible in which the position shift amount calculator  916  calculates, on the basis of the pack packaging image captured by the imager  311  of the appearance inspection device  31 , a non-adhesion region position shift amount A 301  of the non-adhesion regions AA 32  with respect to the positions of the pockets Po 1 . In this case, it is sufficient that the pocket molding position correction amount calculator  918  calculates the pocket molding position correction amount from the non-adhesion region position shift amount A 301 . 
     According to the present configuration, when the cover film F 3  includes the adhesion region AA 31  and the non-adhesion regions AA 32 , shifts between the positions of the pockets Po 1  and the positions of the non-adhesion regions AA 32  can be reduced and, as such, the rate of occurrence of appearance defects in the packaging pack BP 1  can be reduced. 
     In the embodiment, an example is described in which the packaging machine  1  includes the fixed chuck  231 , but the embodiment is not limited thereto and a configuration is possible in which the fixed chuck  231  is not provided. 
     In the embodiment, an example is described in which the packaging machine  1  includes the appearance inspection device  16 , but the embodiment is not limited thereto and a configuration is possible in which the appearance inspection device  16  is not provided. In this case, it is sufficient that the appearance inspection device  31 , for example, takes on the role of the appearance inspection device  16 . Additionally, in the embodiment, an example is described in which the imager  311  of the appearance inspection device  31  images the packaging pack BP 1  disposed at the imaging position while being held by the chuck unit  322   a  of the rotary suction  32 . However, the embodiment is not limited thereto, and the imager  311  of the appearance inspection device  31  may image the packaging pack BP 1  that is placed on the belt conveyor  331  of the pack conveying device  33 . 
     In the embodiment, provided that the position shift amount Δac of the punching position in the conveyance direction of the pack film F 4  is not 0, the conveyance controller  923  may, each time, generate and output, to the output interface  905 , control information for adjusting the rotation angle of the film feeding roller  2811  so that the position shift amount Δac is 0. Alternatively, the conveyance controller  923  may observe, during a predetermined period, the trend of the position shift amount Δac of the punching position in the conveyance direction of the pack film F 4  and, on the basis of an average value or a maximum value of the observed position shift amount Δac, generate and output, to the output interface  905 , control information for adjusting the rotation angle. 
     In the embodiment, provided that the position shift amount ΔAc of the punching position in the width direction of the pack film F 4  is not 0, the film guide position controller  924  may, each time, generate and output, to the output interface  905 , control information for adjusting the position of the film guide  2831  so that the position shift amount ΔAc is 0. Alternatively, the film guide position controller  924  may observe, during a predetermined period, the trend of the position shift amount ΔAc of the punching position in the width direction of the pack film F 4  and, on the basis of an average value or a maximum value of the observed position shift amount ΔAc, generate and output, to the output interface  905 , control information for adjusting the position of the film guide  2831 . 
     In the embodiment, provided that the position shift amounts ΔAs, Δas of the slit forming position in the conveyance direction or the width direction of the pack film F 4  is not 0, the slit position controller  926  may, each time, generate and output, to the output interface  905 , control information for adjusting the position of the guide roller  261  so that the position shift amounts ΔAs, Δas are 0. Alternatively, the slit position controller  926  may observe, during a predetermined period, the trends of the position shift amounts ΔAs, Δas of the slit forming position in the conveyance direction or the width direction of the pack film F 4  and, on the basis of an average value or a maximum value of the observed position shift amounts ΔAs, Δas, generate and output, to the output interface  905 , control information for adjusting the position of the guide roller  261 . 
     In the embodiment, provided that the position shift amounts ΔAm, Δam of the mark position in the conveyance direction or the width direction of the pack film F 4  is not 0, the printing controller  925  may, each time, generate and output, to the output interface  905 , control information for adjusting the position of the print head  272  so that the position shift amounts ΔAm, Δam are 0. Alternatively, the printing controller  925  may observe, during a predetermined period, the trends of the position shift amounts ΔAm, Δam of the mark position in the conveyance direction or the width direction of the pack film F 4  and, on the basis of an average value or a maximum value of the observed position shift amounts ΔAm, Δam, generate and output, to the output interface  905 , control information for adjusting the position of the print head  272 . 
     In the embodiment, provided that the position shift amount ΔAf of the pocket molding position is not 0, the chuck feed controller  922  may, each time, generate and output, to the output interface  905 , control information for adjusting the second reference distance that is the feed amount of the chuck feed  232  so that the position shift amount Δaf is 0. Alternatively, the chuck feed controller  922  may observe, during a predetermined period, the trend of the position shift amount ΔAf of the pocket molding position and, on the basis of an average value or a maximum value of the observed position shift amount ΔAf, generate and output, to the output interface  905 , control information for adjusting the second reference distance. 
     In the embodiment, an example is described in which the control device  90  is provided inside the packaging machine main body  50 , but the embodiment is not limited thereto, and a configuration is possible in which the control device  90  is disposed outside the packaging machine main body  50 . 
     In the embodiment, an example is described in which the film position changer  283  changes the position in the X-axis direction of the pack film F 4  in the punching device  173 . However, the embodiment is not limited thereto and, for example, a configuration is possible in which the conveyor  281  includes a roller driver (not illustrated in the drawings) that changes the position in the X-axis direction of the pack film F 4  by moving the film feeding roller  2811  in the X-axis direction of the pack film F 4 , and the conveyor  281  functions as a film position changer. Moreover, in the printing device  27 , when the pack film F 4  is shifted in the X-axis direction on the conveyor  281 , it is sufficient to move, in correspondence therewith, the position of the print head  272  in the X-axis direction. 
     According to the present configuration, it is possible to reduce the number of components by omitting the film position changer  283  and, as such, it is possible to simplify and reduce the size of the packaging machine  1 . 
     In the embodiment, a configuration is possible in which, when text or a mark is printed on the cover film F 3 , the control device  90  calculates, on the basis of an image of the packaging pack BP 1  obtained by imaging by the appearance inspection device  31 , a relative position shift amount of the cover film F 3  with respect to the container film F 2 . In this case, a configuration is possible in which, for example, the control device  90  calculates a position shift amount of the cover film F 3  with respect to the container film F 2  on the basis of a distance between the text or the mark printed on the cover film F 3  and an edge of the packaging pack BP 1 . Moreover, a configuration is possible in which the control device  90  adjusts, on the basis of the calculated position shift amount of the cover film F 3  with respect to the container film F 2 , the reference position of the cover film F 3  used by the position sensor  154 . 
     In the embodiment, a configuration is possible in which the rotary suction  32  includes a chuck unit  4033  as illustrated in, for example,  FIGS. 17A and 17B . The chuck unit  4033  is detachably fixed to each of the four arms  322  of the rotary suction  32 . The chuck unit  4033  includes a plurality of (six in  FIG. 17B ) suction heads  4333 , a suction pad  4332  that is formed from an elastic material and that is mounted on a tip of each of the plurality of suction heads  4333 , and a head supporter  4331  that has a rectangular box-like shape, collectively supports the plurality of suction heads  4333 , and is detachable from the arm  322 . A pipe  4333   a  maintained in a reduced pressure state when the packaging pack BP 1  is suctioned is provided inside each of the suction heads  4333 . Additionally, a pipe  4331   a  that communicates with each of the pipes  4333   a  is provided inside the head supporter  4331 . Furthermore, a plurality of windows  4331   b  is provided on a side wall of the head supporter  4331 . As a result, the ease of work of a worker to replace the suction pad  4332  can be improved, and the weight of the head supporter  4331  can be reduced. Additionally, a hole (not illustrated in the drawings) into which a square column-like fixing pin (not illustrated in the drawings), that protrudes from the arm  322  toward the +Z-direction side, is fitted is provided on the −Z direction side of the head supporter  4331 . Moreover, the head supporter  4331  is fixed to the arm  322  as a result of the fixing pin of the arm  322  being fitted into the hole. Furthermore, in a state in which the chuck unit  4033  is fixed to the arm  322 , the pipe  4331   a  communicates with an exhaust pipe  322   b  that is provided in the arm  322  and that is connected to a vacuum pump (not illustrated in the drawings). Additionally, at least a portion of the suction pad  4332 , the suction head  4333 , and the head supporter  4331  are formed from resin, for example. In this case, at least a portion of the suction pad  4332 , the suction head  4333 , and the head supporter  4331  may be manufactured using a 3D printer, for example. 
     There are cases in which the packaging pack BP 1  is transferred to the rotary suction  32  in a state in which the entire packaging pack BP 1  is warped (a bent state). In such cases, the focus of the imager  311  in the appearance inspection device  31  will shift, causing the captured image of the target imaging portion of the packaging pack BP 1  to be not sharp, and it may be impossible to accurately recognize the mark provided on the packaging pack BP 1  or inspect for the presence/absence of foreign matter or debris adhered to the packaging pack BP 1 . Additionally, when using the captured image captured by the appearance inspection device  31  to measure the length of the packaging pack BP 1 , the length of the packaging pack BP 1  cannot be accurately measured if the entire packaging pack BP 1  is in a warped state. 
     In response to this, as illustrated in  FIG. 17A , the chuck unit  4033  according to the present modified example holds the packaging pack BP 1  in a state suctioned to the plurality of suction pads  4332 . As a result, the packaging pack BP 1  is flattened and then imaged by the imager  311  and, as such, the sharpness of the captured image obtained by imaging using the imager  311  can be improved. Accordingly, it is possible for the appearance inspection device  31  to more accurately recognize the mark provided on the packaging pack BP 1  or inspect for the presence/absence of foreign matter or debris adhered to the packaging pack BP 1 . Additionally, when using the captured image captured by the appearance inspection device  31  to measure the length of the packaging pack BP 1 , the length of the packaging pack BP 1  can be accurately measured.
