Title: Label formation base material pair and tack labeler

Description:
TECHNICAL FIELD 
     The present invention relates to a tack labeler capable of automatically adhering, onto adherence objects, tack labels that do not require a usage of release papers and are punched out in a shape of an ellipse, circle, or the like; and also relates to a label formation base material pair suitable for the tack labeler. 
     BACKGROUND ART 
     A general tack label is provided as being adhered to a release paper, and thereby has problems such as a high cost due to having the release paper and a need for disposing the release paper as trash after having a tack label detached therefrom. Therefore, in recent years, two sheets of tack labels are provided in a state of being detachably adhered to each other as a label pair without using a release paper. When using the tack label, the two pieces of tack labels are detached and simultaneously adhered onto two adherence objects.

     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     However, the two pieces of tack labels that are detachably adhered to each other, in particular, tack labels that are punched out in a shape of an ellipse, circle, or the like, are difficult to handle when compared to the tack labels that are adhered to a release paper. Therefore, such tack labels are generally provided in a sheet form and are manually handled when being adhered. 
     Therefore, a task of the invention is to provide: a tack labeler capable of automatically adhering, onto adherence objects, tack labels that do not require a usage of release papers and are punched out in a shape of an ellipse, circle, or the like; and a label formation base material pair suitable for the tack labeler. 
     Solutions to the Problems 
     In order to achieve the above described task, the invention according to claim  1  provides a label formation base material pair formed by detachably adhering to each other, on respective adherence surface sides, long strip-like label formation base materials used for cutting therefrom tack labels having a predetermined shape; each of the label formation base materials having formed thereon, successively in a longitudinal direction thereof and at a predetermined interval, cut lines with the shape of the tack labels having connection portions that are uncut at one part thereof and that are located at one end side of the tack labels in the longitudinal direction; cut lines formed on one of the label formation base materials and cut lines formed on the other label formation base material being shifted in position so as not to match to each other. 
     In order to achieve the above described task, the invention according to claim  2  provides a tack labeler comprising: base material pair delivering means for reeling out the label formation base material pair according to claim  1  from a base material pair roll formed by winding the label formation base material pair in a roll shape, and delivering the label formation base material pair from an end on a side of the connection portions of the cut lines having the shape of the tack labels; separating-delivering means for separating the delivered label formation base material pair into the respective label formation base materials, and delivering the respective label formation base materials; cutting means for successively cutting the connection portions formed on each of the separated label formation base materials so as to form individual tack labels; adhering means for adhering the formed individual tack labels onto adherence objects; and base material collecting means for collecting each of the label formation base materials from which the tack labels have been cut off, wherein the separating-delivering means has a pair of separating-delivering rollers that are disposed on both sides of the label formation base material pair so as to nip the label formation base material pair, and that are for delivering each of the separated label formation base materials in directions away from each other while having the label formation base materials follow along outer peripheral surfaces of the separating-delivering rollers. 
     In order to achieve the above described task, the invention according to claim  3  provides a tack labeler comprising: base material pair delivering means for reeling out, from a base material pair roll formed by winding in a roll shape a label formation base material pair formed by detachably adhering to each other, on respective adherence surface sides, long strip-like label formation base materials used for cutting therefrom tack labels having a predetermined shape, and delivering the label formation base material pair; cut-line forming means for successively forming, on the delivered label formation base material pair, cut lines with the shape of the tack labels having connection portions that are uncut at one part thereof and that are located at a downstream side of a delivering direction; separating-delivering means for separating, into the respective label formation base materials, the label formation base material pair having formed thereon the cut lines having the shape of the tack labels, and delivering the respective label formation base materials; cutting means for successively cutting the connection portions formed on each of the separated label formation base materials so as to form individual tack labels; adhering means for adhering the formed individual tack labels onto adherence objects; and base material collecting means for collecting each of the label formation base materials from which the tack labels have been cut off, wherein the separating-delivering means has a pair of separating-delivering rollers that are disposed on both sides of the label formation base material pair so as to nip the label formation base material pair, and that are for delivering each of the separated label formation base materials in directions away from each other while having the label formation base materials follow along outer peripheral surfaces of the separating-delivering rollers. 
     In order to achieve the above described task, the invention according to claim  4  provides a tack labeler comprising: base material pair delivering means for reeling out, from a base material pair roll formed by winding in a roll shape a label formation base material pair formed by detachably adhering to each other, on respective adherence surface side, long strip-like label formation base materials used for cutting therefrom tack labels having a predetermined shape, and delivering the label formation base material pair; separating-delivering means for separating the delivered label formation base material pair into respective label formation base materials, and delivering the respective label formation base materials; cut-out means for cutting out each of the separated label formation base materials into the predetermined shape to form individual tack labels; adhering means for adhering the individual tack labels cut out from the label formation base material onto adherence objects; and base material collecting means for collecting each of label formation base materials from which the tack labels have been cut out, wherein the separating-delivering means has a pair of separating-delivering rollers that are disposed on both sides of the label formation base material pair so as to nip the label formation base material pair, and that are for delivering each of the separated label formation base materials in directions away from each other while having the label formation base materials follow along outer peripheral surfaces of the separating-delivering rollers. 
     Advantageous Effects of the Invention 
     As described above, in the label formation base material pair which is the invention according to claim  1 , formed on the pair of label formation base materials detachably adhered to each other on respective adherence surface sides are cut lines with the shape of the tack labels having connection portions that are uncut at one part thereof and that are located at one end side of the tack labels in the longitudinal direction. Therefore, when the label formation base materials adhered to each other are detached starting at the one end side in the longitudinal direction, cut-line enclosed portions that are to be the tack labels can also be detached and separated with certainty. 
     Furthermore, on the label formation base material pair, cut lines formed on one of the label formation base materials and cut lines formed on the other label formation base material are shifted in position so as not to match each other. Therefore, the portions enclosed by the cut lines formed on one of the label formation base materials that are to be the tack labels are adhered and held outside the cut-line enclosed portions that are to be the tack labels on the other label formation base material. Thus, the cut-line enclosed portions that are to be the tack labels on both of the label formation base materials do not become loose, and thereby the label formation base material pair can be reeled out and delivered smoothly with certainty. 
     With the tack labeler, which is the invention according to claim  2  and which is configured as described above, when the separating-delivering roller is rotated in a state where a leading end of the label formation base material pair delivered by the base material pair delivering means is split to follow along the outer peripheral surfaces of the separating-delivering rollers, the two sheets of the label formation base materials that are adhered to each other become separated. Here, since the connection portions of the cut lines formed on the two sheets of label formation base materials are located on the downstream side of the delivering direction of the label formation base materials, the cut-line enclosed portions that are to be tack labels are also separated with certainty due to the connection portions. Then, by successively cutting the connection portions formed on each of the separated label formation base materials by using the cutting means, the individual tack labels are formed and then adhered, with certainty, onto the adherence objects by the adhering means. 
     With the tack labeler, which is the invention according to claim  3 , when the separating-delivering rollers are rotated in a state where a leading end of the label formation base material pair delivered by the base material pair delivering means is split to follow along the outer peripheral surfaces of the separating-delivering rollers, the two sheets of the label formation base materials that are adhered to each other become separated. However, before the two sheets of the label formation base materials are separated, cut lines are successively formed on the label formation base material pair by the cut-line forming means in a shape of the tack labels having the connection portions that are uncut at one part thereof and that are located at a downstream side of the delivering direction. Due to the connection portions, the cut-line enclosed portion that are to be tack labels are also separated with certainty. Then, by successively cutting the connection portions formed on each of the separated label formation base materials by using the cutting means, the individual tack labels are formed and then adhered, with certainty, onto the adherence objects by the adhering means. 
     With the tack labeler, which is the invention according to claim  4 , when the separating-delivering rollers are rotated in a state where a leading end of the label formation base material pair delivered by the base material pair delivering means is split to follow along the outer peripheral surfaces of the separating-delivering rollers, the two sheets of the label formation base material that are adhered to each other become separated. Then, by successively cutting out each of the separated label formation base materials by the cut-out means, the individual tack labels are formed and then adhered, with certainty, onto the adherence objects by the adhering means.

     DESCRIPTION OF EMBODIMENTS 
       FIGS. 1 through 3  show a tack labeler  1 . As shown in  FIG. 9  ( a ) and ( b ), long strip-like label formation base materials LM, from which tack labels having a predetermined shape are to be cut, are detachably adhered to each other on respective adherence surface sides to form a label formation base material pair LMP. Cut lines CL, which have the shape of the tack labels having connection portions cp that are uncut at one part thereof and that are located at one end side of the tack labels in a longitudinal direction thereof, are successively formed on each of the label formation base materials LM with a predetermined interval in the longitudinal direction. In the label formation base material pair LMP, cut lines CL formed on one of the label formation base materials LM and cut lines CL formed on the other label formation base material LM are shifted in position in the longitudinal direction of the label formation base materials LM so as not to match each other. The tack labeler  1  reels out the label formation base material pair LMP from a base material pair roll MPR that is formed by winding the label formation base material pair LMP in a roll shape, detaches the label formation base materials LM from each other, then successively cuts connection portions cp of the cut lines CL formed on each of the label formation base materials LM to form the tack labels, and adheres the tack labels onto trunk portions of cup-like containers C. 
     As shown in  FIGS. 11 and 12 , the label formation base materials LM include: a base material layer BL formed from plastic film, synthetic paper, or the like; an indicated print layer IL laminated on an external surface of the base material layer BL; adhesive layers AL formed from hot melt resin laminated on an internal surface of the base material layer BL; and non-adhesive layers PL formed from silicon resin. The adhesive layers AL and the non-adhesive layers PL are alternately arranged in the width direction of the base material layer BL. The label formation base materials LM included in the label formation base material pair LMP are adhered to each other. In this state, in order to prevent the adhesive layers AL of both of the label formation base materials LM from making contact with each other, the non-adhesive layers PL are arranged so as to be shifted from each other in the width direction. 
     As shown in  FIGS. 1 through 3 , the tack labeler  1  includes: a roll holder  10  for rotatably holding the base material pair roll MPR; a reeling-out unit  20  for reeling out the label formation base material pair LMP from the base material pair roll MPR set on the roll holder  10 ; a base material pair accumulation unit  30  for accumulating the label formation base material pair LMP reeled out by the reeling-out unit  20 ; a separating-delivering unit  40  for pulling out the label formation base material pair LMP from the base material pair accumulation unit  30 , separating the label formation base material pair LMP into respective label formation base materials LM, and delivering the respective label formation base materials LM; cutting units  50  having a guillotine-type cutter for successively cutting the connection portions cp of the cut lines CL formed on each of the label formation base materials LM delivered by the separating-delivering unit  40  to form individual tack labels L; adhering units  60  for adhering the tack labels L cut off from each of the label formation base materials LM onto containers C conveyed to adherence positions; base material collecting units  70  for winding up and collecting each of the label formation base materials LM from which the tack labels have been cut off; a main control unit which is not illustrated and which is for collectively controlling actions of each of the units; and a sub control unit which is not illustrated and which controls delivering actions of the label formation base material pair LMP by the separating-delivering unit  40  while cooperating with the main control unit. A mark sensor  81 , which is for detecting a mark printed on a predetermined position corresponding to a tack label on the label formation base material pair LMP, is installed between the base material pair accumulation unit  30  and the separating-delivering unit  40 . 
     As shown in  FIGS. 1 and 2 , the reeling-out unit  20  includes: a reeling-out nip roller  21  including a driving roller  22  and a follower roller  23  that are provided so as to stand on a base plate  2 ; a geared motor  24  for rotating the driving roller  22  of the reeling-out nip roller  21 ; and a guide roller  25  interposed between the reeling-out nip roller  21  and the base material pair roll MPR set on the roll holder  10 . When the driving roller  22  is rotated by the geared motor  24  in a state where the label formation base material pair LMP is nipped by the driving roller  22  and the follower roller  23 , the label formation base material pair LMP is reeled out from the base material pair roll MPR set on the roll holder  10 . 
     As shown in  FIGS. 1 and 2 , the base material pair accumulation unit  30  includes: a slide base  31  that is installed on a side opposite to the follower roller  23  with regard to the driving roller  22  of the reeling-out unit  20 , and that extends in the width direction of the base plate  2 ; a slider  32  that moves along the slide base  31 ; a dancer roller  33  provided so as to stand on the slider  32  in a rotatable manner; a coil spring  34  biasing the slider  32  toward one end side (outer side in the width direction of the base plate  2 ) of the slide base  31 ; and a guide roller  35 . The label formation base material pair LMP reeled out by the reeling-out nip roller  21  is alternately placed on the driving roller  22 , the dancer roller  33 , and the guide roller  35 . 
     A roll detection sensor  36  including a transmissive-type photoelectric sensor for detecting the dancer roller  33  is installed beside the moving pathway of the dancer roller  33  at a middle part of the moving range of the dancer roller  33 . When an accumulation amount of the label formation base material pair LMP becomes large, i.e., when the dancer roller  33  moves toward the outer side of the base plate  2  in the width direction, the dancer roller  33  is detected by the roll detection sensor  36 . However, when the accumulation amount of the label formation base material pair LMP becomes small, i.e., when the dancer roller  33  moves toward the inner side of the base plate  2  in the width direction, the dancer roller  33  is not detected by the roll detection sensor  36 . 
     The control units that are not illustrated conduct ON/OFF control of the geared motor  24  of the reeling-out unit  20 , such that: while the dancer roller  33  is not detected by the roll detection sensor  36 , i.e., while the accumulation amount of the label formation base material pair LMP is insufficient, the reeling-out action by the reeling-out unit  20  for the label formation base material pair LMP is executed; and when the dancer roller  33  is detected by the roll detection sensor  36 , i.e., when the label formation base material pair LMP has accumulated sufficiently, the reeling-out action by the reeling-out unit  20  for the label formation base material pair LMP is stopped. 
     As shown in  FIGS. 4 through 6 , the separating-delivering unit  40  includes: a pair of suction driving rollers  41 A and  41 B installed so as to nip the label formation base material pair LMP from both sides thereof and to penetrate the base plate  2 ; a servomotor  47  for rotating the suction driving roller  41 A on one side; and auxiliary rollers  49  and  49  for nipping each of the label formation base materials LM between the rotating suction driving rollers  41 A and  41 B. Two sheets of the label formation base materials LM are continuously separated from the label formation base material pair LMP by delivering the separated label formation base materials LM in directions separating away from each other while having the label formation base materials LM follow along the outer peripheral surfaces of the pair of suction driving rollers  41 A and  41 B. 
     As shown in  FIG. 4 , and  FIG. 6  ( a ) and ( c ), the suction driving roller  41 A on one side includes a central shaft  42  penetrating the base plate  2 ; and a roller tube  44  that is rotatably supported by the central shaft  42  via a bearing and that has numerous suction holes  44   a  each of which opens to the inner peripheral surface side at one end and opens to the outer peripheral surface side at the other end. The top end of the central shaft  42  is fixed by one end of a support piece  40   a  whose other end is supported by a support rod provided so as to stand on the base plate  2  above the base plate  2 , and the bottom end of the central shaft  42  is fixed to a flat bar  40   c  whose respective ends are attached to the base plate  2  via a support rod below the base plate  2 . 
     As shown in  FIG. 6  ( a ), the central shaft  42  includes: a main suction passage  42   a  that extends in the vertical direction through the central part of the central shaft  42  and whose top end is blocked; a recessed portion  42   b  formed at a portion, from a position at which the roller tubes  44  and  44  of the pair of the suction driving roller  41 A and  41 B are located closest to each other on the outer peripheral surface, to a position located 90 degrees away from said position in the delivering direction of the label formation base materials LM; and five communication passages  42   c  that allow communication between the main suction passage  42   a  and the recessed portion  42   b  and that are arranged one above another. A connection elbow  42   d  for a suction tube for connecting to a suction blower  82  via a pressure regulating valve is attached at an open bottom end of the main suction passage  42   a.    
     As shown in  FIG. 4 , and  FIG. 6  ( b ) and ( c ), the suction driving roller  41 B on the other side also includes: a central shaft  43  penetrating the base plate  2 ; and the roller tube  44  that is rotatably supported by the central shaft  43  via a bearing and that has numerous suction holes  44   a  each of which opens to the inner peripheral surface side at one end and opens to the outer peripheral surface side at the other end. However, the top end of the central shaft  43  is rotatably supported by one end of a support piece  40   b  whose other end is supported by a support rod provided so as to stand on the base plate  2  above the base plate  2 , and the bottom end of the central shaft  43  is rotatably support by the flat bar  40   c  below the base plate  2 . 
     As shown in  FIG. 3  and  FIG. 6  ( b ), the central shaft  43  includes: a lower shaft  43 D rotatably supported by the flat bar  40   c ; a middle shaft  43 M installed continuously to the lower shaft  43 D in a state of being eccentric with regard to a rotation center of the lower shaft  43 D; an upper shaft  430  installed continuously to the middle shaft  43 M such that the rotation center of the upper shaft  43 U matches the rotation center of the lower shaft  43 D; a knob  45  fixed on the upper shaft  430 ; and a coil spring  46  having one end thereof coupled to the support member  40   d  attached to the lower shaft  43 D and the other end coupled to a support member  40   e  attached to the flat bar  40   c . By rotating the knob  45 , the roller tube  44  rotatably supported by the middle shaft  43 M is brought close to and away from the roller tube  44  of the suction driving roller  41 A on one side. In addition, the middle shaft  43 M (roller tube  44 ) is constantly biased by the coil spring  46  in a direction toward the roller tube  44  of the suction driving roller  41 A on the other side. Therefore, when setting the label formation base material pair LMP, the label formation base material pair LMP is nipped between the roller tubes  44  and  44  of the pair of suction driving rollers  41 A and  41 B, by rotating the knob  45  to separate the roller tube  44  of the suction driving roller  41 B on one side from the roller tube  44  of the suction driving roller  41 A on the other side, inserting the label formation base material pair LMP between the roller tubes  44  and  44 , and then releasing the knob  45  to have the roller tube  44  of the suction driving roller  41 B on the other side restored to an original position thereof through a bias force of the coil spring  46 . 
     In addition, similar to the central shaft  42  of the suction driving roller  41 A, the central shaft  43  of the suction driving roller  41 B on one side includes: a main suction passage  43   a  that extends in the vertical direction through the central part of the central shaft  43  and whose top end is blocked; a recessed portion  43   b  formed at a portion, from a position at which the roller tubes  44  and  44  of the pair of the suction driving rollers  41 A and  41 B are located closest to each other on the outer peripheral surface of the middle shaft  43 M, to a position located 90 degrees away from said position in the delivering direction of label formation base materials LM; five communication passages  43   c  that allow communication between the main suction passage  43   a  and the recessed portion  43   b  and that are arranged one above another. A connection elbow  43   d  for a suction tube for connecting to the suction blower  82  via a pressure regulating valve is attached at an open bottom end of the main suction passage  43   a.    
     The roller tube  44  that is a part of each of the suction driving rollers  41 A and  41 B includes: a main body portion  44 A formed from aluminum; and a cover portion  44 B formed from urethane rubber for covering the outer peripheral surface of the main body portion  44 A in order to prevent sliding of the label formation base material pair LMP that is to be nipped and delivered and sliding of the two sheets of the label formation base materials LM obtained through separation of the label formation base material pair LMP. The suction holes  44   a  are formed on both the main body portion  44 A and the cover portion  44 B. 
     Furthermore, gears  48 A and  48 B, which are meshed to each other and which rotate together with the respective roller tubes  44  and  44 , are attached to the pair of the suction driving rollers  41 A and  41 B. Since the gear  48 A of the suction driving roller  41 A on one side is meshed together with a gear attached to a drive shaft of the servomotor  47 , a rotational driving force of the servomotor  47  is transferred to the pair of the suction driving rollers  41 A and  41 B, and thereby enables the pair of the suction driving rollers  41 A and  41 B to rotate in opposite directions. 
     The auxiliary rollers  49 , which make contact with the adherence surface side of label formation base materials LM, are arranged at two height levels to allow adjusting of height positions, have a disc shape whose height is smaller than the width of the non-adhesive layers PL in label formation base materials LM as shown in  FIG. 3 , and are installed at height positions corresponding to the non-adhesive layers PL in order to avoid making contact with the adhesive layers AL on the adherence surfaces of the label formation base materials LM as shown in  FIG. 7 . Therefore, an adhesive forming the adhesive layers AL will not stick to the auxiliary rollers  49 , and thereby label formation base materials LM can be delivered smoothly. 
     A so-called pitch control is conducted on the separating-delivering unit  40  by the sub control unit in cooperation with the main control unit for intermittently delivering a predetermined amount of the label formation base material pair LMP. After the mark sensor  81  detects the mark printed on the label formation base material pair LMP, the separating-delivering unit  40  delivers the label formation base material pair LMP for the predetermined amount that is determined in advance, such that the connection portions formed on the separated label formation base materials LM are moved to a cut position of the cutting units  50 . 
     As described above, in the label formation base material pair LMP, since the label formation base materials LM are shifted in position from each other in the longitudinal direction thereof such that the cut lines CL formed on one of the label formation base materials LM and the cut lines CL formed on the other label formation base material LM do not match each other, a distance D 1  from a separation position of the label formation base material LM to a stop position of a connection portion cp in a cut line CL of one of the label formation base materials LM differs from a distance D 2  from the separation position of the label formation base material LM to a stop position of a connection portion cp in a cut line CL of the other label formation base material LM as shown in  FIG. 10 , even when the separating-delivering unit  40  separates and delivers the mutually adhered label formation base materials LM for the predetermined amount. Therefore, the cutting units  50  that successively cut the connection portions cp of the cut lines CL formed on each of the separated label formation base materials LM are installed so as to be also shifted in position from one another, in accordance with the stop positions of the connection portions cp of the cut lines CL of each of the label formation base materials LM. 
     As shown in  FIGS. 4 and 5 , the adhering units  60  include: generally rectangular-shaped suction plates  61  that are divided into circular movable portions  62  which are slightly smaller than the tack labels L and fixing portions  63  located outward of the movable portions  62 , and that suction and hold each of the label formation base materials LM separated and delivered by the separating-delivering unit  40  for the predetermined amount; and drive cylinders  64  for moving the movable portions  62  of the suction plates  61  forward and backward. 
     On each of the movable portions  62  of the suction plates  61 , a single suction hole  62   a  is formed on a suctioning-holding surface of the movable portion  62 , and a comb-shaped suction groove  62   b  that communicates with the suction hole  62   a  is formed. On each of the fixing portions  63  of the suction plates  61 , two suction holes  63   a  and  63   a  are formed on a suctioning-holding surface of the fixing portion  63 , and a suction groove  63   b  that communicates with the two suction holes  63   a  and  63   a  are formed so as to surround the circular movable portion  62 . 
     The suction plates  61  are installed between the respective cutting units  50  and  50  and the respective suction driving rollers  41 A and  41 B of the separating-delivering unit  40  so as to be adjacent to both. The suction plate  61  installed on a side of the cutting unit  50  distal to the separation position of the label formation base materials LM is formed wider than the suction plate  61  installed on a side of the other cutting unit  50 . 
     The outer peripheral edge of each of the movable portions  62  of the suction plates  61  is arranged such that an end edge on the side of the cutting unit  50  in the fixing portion  63  matches the outer peripheral edge of the movable portions  62 . Thus, when a connection portion cp in a cut line CL formed on the label formation base material LM reaches the cut position, each of the movable portions  62  will be located inside the portion that is enclosed by the cut line CL formed on each of the label formation base materials LM so as to be a tack label L. 
     In addition, each of the suction holes  62   a  and  63   a  of the suction plates  61  is connected to the suction blower  82  via a vacuum valve (not illustrated) that uses air as a drive source, and as described in the following, suctioning action by the suction plates  61  is intermittently conducted by having the control unit, which is not illustrated, operate an air valve  83  for opening and closing the vacuum valve through a control of the supply of air for driving the vacuum valve. 
     When each of the separated label formation base materials LM is delivered for the predetermined amount and is stopped, the suctioning action by the suction plates  61  is initiated and the label formation base material LM is held by the suction plates  61 . At this moment, each of the movable portions  62  of the suction plates  61  is located inside the portion that is enclosed by the cut line CL formed on each of the label formation base materials LM so as to be the tack label L. 
     Here, when the cutting units  50  cut the connection portions cp of the cut lines CL formed on each of the label formation base materials LM, the tack labels L are cut off from each of the label formation base materials LM, and the tack labels L that have been cut off are suctioned and held only by the movable portions  62  of the suction plates  61 . Subsequently, the movable portions  62  that have suctioned and held the tack labels L advance, and the tack labels L are adhered to trunk portions of containers C conveyed to adherence positions by container conveyance units. Then, the suctioning action by the suction plates  61  is stopped, and the suction plates  61  retreat to initial positions. 
     As shown in  FIGS. 4 and 5 , the base material collecting units  70  include: wind-up reels  71  that are supported by the base plate  2  via bearings, and that wind up the label formation base materials LM from which the tack labels L have been cut off by the cutting units  50 ; geared motors  72  for rotating the wind-up reels  71 ; and guide rollers  73  provided so as to stand on the base plate  2 . The geared motors  72  conduct a constant-torque control for holding a constant torque by using a cycle-converting inverter. Therefore, the wind-up reels  71  will not rotate when the delivering of the label formation base materials LM by the separating-delivering unit  40  is stopped; however, when the delivering of the label formation base materials LM by the separating-delivering unit  40  is initiated, the wind-up reels  71  rotate to wind up the label formation base materials LM from which the tack labels L have been cut off. 
     With the tack labeler  1  as configured as described above, the respective label formation base materials LM adhered to each other are separated when the suction driving rollers  41 A and  41 B are rotated in a state where a leading end of the label formation base material pair LMP delivered from the reeling-out unit  20  is split to follow along the outer peripheral surfaces of the suction driving rollers  41 A and  41 B of the separating-delivering unit  40 . At this moment, since the connection portions cp of the cut lines CL formed on each of the label formation base materials LM are located on the downstream side of the delivering direction of the label formation base materials LM, the portions that are enclosed by the cut lines CL and that are to be tack labels are also separated with certainty due to the connection portions cp. Then, by successively cutting the connection portions cp formed on each of the separated label formation base materials LM by the cutting units  50 , the individual tack labels L are formed, and then, the tack labels L are adhered onto the containers C by the adhering units  60  with certainty. 
     Furthermore, on the label formation base material pair LMP, the cut lines CL formed on one of the label formation base materials LM and the cut lines CL formed on the other label formation base material LM are shifted in position in the longitudinal direction of the label formation base materials LM so as not to match each other. Therefore, as shown in  FIG. 9 , the portions enclosed by the cut lines CL formed on one of the label formation base materials LM so as to be tack labels are adhered and held outside the portions enclosed by the cut lines CL formed on the other label formation base material LM so as to be tack labels. Thus, portions enclosed by the cut lines CL formed on both of the label formation base materials LM so as to be tack labels do not become loose, and thereby the label formation base material pair LMP can be reeled out and delivered smoothly with certainty. 
     Another embodiment is shown in  FIGS. 13 through 15 . A tack labeler  1 A here has basically the same configuration as that of the above described tack labeler  1 , and thereby the same reference characters are given to the same components and descriptions of those are omitted, and different components will be described in detail. 
     Used for the above described the tack labeler  1  are the label formation base material pair LMP having formed thereon in advance the cut lines CL with the shape of the tack labels having the connection portions cp that are uncut at one part thereof and that are located at one end side of the tack labels in the longitudinal direction of the label formation base materials LM which are detachably adhered to each other. However, the tack labeler  1 A uses a label formation base material pair LMP 1  obtained by simply detachably adhering long strip-like label formation base materials LM on adherence surface sides thereof, and the tack labeler  1 A forms the tack label-shaped cut lines CL on the label formation base materials LM forming the label formation base material pair LMP 1 . Therefore, a laser cutter  90  is mounted on the tack labeler  1 A, and forms, on the label formation base material pair LMP 1  and at a location between the base material pair accumulation unit  30  and the separating-delivering unit  40 , the cut lines CL with the shape of the tack labels having the connection portions cp that are uncut at one part thereof and that are located at the downstream side of the delivering direction. 
     With the tack labeler  1 A, the label formation base materials LM, on which the cut lines CL are to be formed by the laser cutter  90 , are separated by the separating-delivering unit  40  immediately after the cut lines CL are formed. Therefore, with regard to the cut lines CL formed on the label formation base material pair LMP 1 , it is not necessary to shift the positions of the cut lines CL formed on one of the label formation base materials LM from the positions of the cut lines CL formed on the other label formation base material LM in the longitudinal direction of the label formation base materials LM so as not to match each other as in the case with the label formation base material pair LMP used in the above described tack labeler  1 . Thus, the cut lines CL of the label formation base material pair LMP 1  may be formed such that the cut lines CL formed on both label formation base materials LM match each other (cf.,  FIG. 16  ( a ) and ( b )). 
     Furthermore, since the cut lines CL formed on one of the label formation base materials LM and the cut lines CL formed on the other label formation base material LM are not shifted in position in the longitudinal direction of the label formation base materials LM, a distance D 1  from a separation position of the label formation base materials LM to a stop position of the connection portion cp in the cut line CL of one of the label formation base materials LM matches a distance D 2  from the separation position of the label formation base materials LM to a stop position of a connection portion cp in the cut lines CL of the other label formation base material LM, as shown in  FIG. 17 . Thus in the tack labeler  1 A, one pair of the cutting units  50  are installed at positions equally distant from the separation position of the label formation base materials LM, and one pair of the suction plates  61  of the adhering units  60  are also set to have identical widths. 
     It should be noted that, although the laser cutter  90  is used as the cut-line forming means for forming the cut lines CL on the label formation base material pair LMP 1  in the tack labeler  1 A, the present invention is not limited thereto; and the cut lines CL may be formed on the label formation base material pair LMP 1  by pressing the label formation base material pair LMP 1  using a punch-out mold having a blade with a similar cut line shape. 
     Furthermore, the cut lines CL may be formed on the label formation base material pair LMP 1  when separating the label formation base material pair LMP 1  into two sheets of the label formation base materials LM, by providing a function as the cut-line forming means such as a die roll or an anvil roll on the separating-delivering rollers such as the suction driving rollers  41 A and  41 B included in the separating-delivering unit  40 . 
     Another embodiment is shown in  FIGS. 18 through 23 . A tack labeler  1 B here also has basically the same configuration as that of the above described tack labeler  1 , and thereby the same reference characters are given to the same components and descriptions of those are omitted, and different components will be described in detail. 
     With the above described tack labeler  1 , the individual tack labels L are formed by cutting the connection portions cp by the cutting units  50 , by using the label formation base material pair LMP having formed thereon in advance the cut lines CL with the shape of the tack labels having the connection portions cp that are uncut at one part thereof and that are located at one end side of the tack labels in the longitudinal direction of the label formation base materials LM which are detachably adhere to each other. However, the tack labeler  1 B uses the label formation base material pair LMP 1  obtained by simply detachably adhering the long strip-like label formation base materials LM on the adherence surface sides thereof; and the individual tack labels L are formed by separating the label formation base materials LM by the separating-delivering unit  40  and then punching out the label formation base materials LM as tack label shapes at adherence positions of the tack labels L. Thus, punch-out units  100  are installed on the tack labeler  1 B instead of the cutting units  50  of the tack labeler  1 . 
     As shown in  FIGS. 19 through 21 , the punch-out units  100  include: punch-out molds  101  having formed thereon tack label-shaped punch-out blades; drive cylinders  102  for moving, such that suction surfaces of the movable portions  62  and the suction surfaces of the fixing portions  63  become the same plane, the punch-out molds  101  back and forth with regard to the suction plates  61  in the forward side of the suction plates  61  when the movable portions  62  are retreated; and drive cylinders  103 , which work together with the drive cylinders  102 , for moving the punch-out molds  101  back and forth between forward positions and side-retreat positions of the suction plates  61 . In a state where the drive cylinders  102  and the punch-out molds  101  are retreated on the side, the movable portions  62  of the suction plates  61  can move to and from containers C stopped in the front. 
     Thus, with the tack labeler  1 B, when delivering action for the label formation base materials LM stops, as shown in  FIG. 22  ( a ) and ( b ), predetermined-shaped tack labels L are punched out from the label formation base materials LM by pressing the label formation base materials LM to the fixing portions  63  of the suction plates  61  by the punch-out molds  101 , and the punched-out tack labels L are suctioned and held by the movable portions  62  of the suction plates  61 . Subsequently, as shown in  FIG. 23  ( a ) and ( b ), the drive cylinders  102  and the punch-out molds  101  retreat on the side, and the movable portions  62  of the suction plates  61  suctioning and holding the tack labels L advance, resulting in the tack labels L adhering to the containers C stopped in the front at the adherence positions. 
     It should be noted that, in the above described embodiments, although the separating-delivering unit  40  includes the auxiliary rollers  49  and  49  for nipping each of the label formation base materials LM between the suction driving rollers  41 A and  41 B, the auxiliary rollers  49  and  49  can be omitted. 
     Furthermore, when using the auxiliary rollers  49  and  49 , instead of the suction driving rollers  41 A and  41 B, a nip roller including a follower roller and a driving roller not having a suction function may be disposed at the position of the suction driving rollers  41 A and  41 B. 
     Furthermore, in the above described label formation base material pair LMP, although the tack label-shaped cut lines CL have the connection portions cp that are perfectly uncut, the connection portions cp may be perforations. 
     Furthermore, in the above described label formation base material pair LMP, although the cut lines CL formed on one of the label formation base materials LM and the cut lines CL formed on the other label formation base material LM are shifted in position in the longitudinal direction of the label formation base materials LM so as not to match each other, the present invention is not limited thereto; and, it is also possible to, for example, shift the positions by rotating either one of the cut lines CL or both of the cut lines CL by using mutually matched connection portions cp as centers as shown in  FIG. 24 , or shift the positions in the width direction of the label formation base materials LM as shown in  FIG. 25 . 
     INDUSTRIAL APPLICABILITY 
     The invention can be applied when automatically adhering tack labels that do not use release papers and that are punched out in shapes such as an ellipse, circle, or the like.
