Description:
The entire disclosure of Japanese Patent Application No. 2004-136133 filed on Apr. 30, 2004 and Japanese Patent Application No. 2005-107122 filed on Apr. 4, 2005, including specification, claims, drawings and summary, is incorporated herein by reference in its entirety. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a delivery in a folding machine of a web-fed rotary press. 
   2. Description of Related Art 
   A web-fed rotary press is provided with a folding machine for cutting a web at predetermined lengths, which is dried and cooled after printing, and then folding the cut web in the width direction or the longitudinal direction. The signature which is folded and formed by the folding machine is sent to a delivery, and is transported to a paper delivery belt by rotation of a fan wheel. Thereafter, the signature is delivered from the printing press by this paper delivery belt. 
   The fan wheel is provided with a number of vanes, and is designed to receive and hold the signature between the vanes, and transfer the signature onto the transporting belt as the fan wheel rotates. Such a fan wheel is designed to restrict the signature in the width direction which is held by the fan wheel by providing a side guide to each side of the fan wheel. Incidentally, since the folding specification such as one time folding, two-time folding or delta folding is selectively employed in the folding machine, the paper width of the signature, which is transported from the folding machine into the delivery, differs for each folding specification. 
   For this reason, depending on the folding specification, it is necessary to move the side guide in accordance with the length in the width direction of the signature, and a case where the side guide is placed in the fan wheel including a plurality of vanes with predetermined spacing in the width direction of the signature, occurs. For such movement of the side guide at the time of changing the folding specification, a method in which the side guide is temporarily detached and again fixed in a predetermined position, is conventionally adopted. Thus, there have been possibilities that tools are required and that a part is lost. In addition, there is a problem that adjustment of the mounting position of the side guide is troublesome. 
   A delivery for solving such problems is disclosed in Japanese Patent Application Laid-open No. 2000-86039, for example. In the conventional delivery, the problems are solved by providing, to a side guide, supporting mechanism which allows for movement between a guide position for guiding the signature held in the fan wheel and a retraction position for retraction from the fan wheel at the time of changing the folding specification. 
   In the above-described conventional delivery, however, although the supporting mechanism allowing for movement of the side guide is provided, since the mechanism is operated manually, the amount of adjustment is different depending on the operators performing the position adjustment of the side guide. In some cases, there is a possibility that a paper jam occurs. On the other hand, in the transport position of the signature transported by the fan wheel, some errors occur in the width direction in response to the speed of the printing press. Especially at the time of starting up the printing press, since the signature is transported at a low speed, the signature has little momentum, lacks stability, and is thus often transported askew. Accordingly, even when the side guide is successfully adjusted in accordance with the width direction of the signature, a glitch that the signature cannot be appropriately guided by the side guide has occurred at the time of low speed operation. 
   SUMMARY OF THE INVENTION 
   Accordingly, the present invention is to solve the above-described problem. To that end, the present invention provides a delivery which automatically moves guide members at the time of changing the folding specification.

   As shown in the drawings, a fan wheel  2  is pivotally supported between a pair of frames  1   a  and  1   b  of the delivery. An arrow in  FIG. 1  indicates the rotation direction of the fan wheel  2 . With further reference to  FIGS. 2 and 5 , the fan wheel  2  includes four fan wheel members  2   a ,  2   b ,  2   c  and  2   d , and these are supported on a supporting shaft  3  with predetermined spacing. Among these, the fan wheel members  2   a  and  2   b  are splined on a spline portion  3   a  of the supporting shaft  3  to be able to rotate with the supporting shaft  3 , and are movable in the axis direction of the supporting shaft  3 . Moreover, the fan wheel members  2   a  and  2   b  are connected to fan-wheel air cylinders  4  and  5  provided as fan wheel moving means. 
   The fan-wheel air cylinders  4  and  5  are attached to a supporting plate  6 , which is disposed between the frames  1   a  and  1   b . Sliding members  8  and  9 , which slide on a rail  7  attached on the supporting plate  6 , are attached to one ends of the air cylinders  4  and  5 . The sliding members  8  and  9  support the fan wheel members  2   a  and  2   b  via supporting members  10  and  11 . The fan wheel members  2   a  and  2   b  are pivotally supported by bearings  12  and  13  attached to one ends of the supporting members  10  and  11 . Moreover, strippers  14  and  15  are attached to the supporting members  10  and  11 . 
   Above the fan wheel  2 , a pair of transporting belts  16   a  and  16   b  for transporting a signature (the signature  65 ,  66  or  67  described later) provided as a sheet are looped over roller members  17  and  18 . The signature which has been transported is ejected from between the roller members  17  and  18 , and held by the fan wheel  2 . On the other hand, below the fan wheel  2 , provided is a paper delivery belt  19  for receiving the signature which is discharged from the fan wheel  2  and then delivering the signature to a predetermined position. Arrows in  FIG. 1  indicate the transporting directions of the transporting belts  16   a  and  16   b  and the paper delivery belt  19 . 
   In addition, referring to  FIGS. 4 ,  6  and  7 , a pair of plate-shaped side guides  20  and  21  for restricting the signature in the width direction, which is temporarily held by the fan wheel  2 , are disposed inside the frames  1   a  and  1   b , the side guides  20  and  21  being placed on both sides of the fan wheel  2 . 
   A pair of brackets  22   a  and  22   b  are attached to the back face of the side guide  20 , and slide rods  23   a  and  23   b  are supported by the upper and lower portions of the brackets  22   a  and  22   b . A supporting block  24  slidably supports the slide rods  23   a  and  23   b , and is supported by the frame  1   b  via an arm  25 . 
   On the other hand, a pair of brackets  26   a  and  26   b  are attached to the back face of the side guide  21 , and a side-guide rodless air cylinder  27  provided as side-guide radial-direction moving means is supported between the brackets  26   a  and  26   b . A supporting plate  28  is supported by a moving block  27   a  of the side-guide rodless air cylinder  27 , and supports moving rods  28   a  and  28   b , which are disposed perpendicularly to the side-guide rodless air cylinder  27 . The moving rods  28   a  and  28   b  are supported by a supporting block  29  outside the frame  1   a . The moving rod  28   b  has a rack shape formed, and the rack and an end of a gear  30  engage with each other. The other end of the gear  30  is connected with an end of a gear  31 , and engages with a gear  33   a  of a side-guide encoder  33 . A side-guide drive motor  32  provided as side-guide width-direction moving means is attached to the gear  31 . ( FIGS. 5 and 9 ) 
   A back guide  34  for restricting the signature in the longitudinal direction (the radial direction of the fan wheel  2 ) which is temporarily held by the fan wheel  2  is disposed inside the side guides  20  and  21 . The back guide  34  includes three back guide members  34   a ,  34   b  and  34   c . The back guide members  34   a  to  34   c  are supported with predetermined spacing in the width direction of the signature, and are disposed between the fan wheel members  2   a ,  2   b ,  2   c  and  2   d , respectively. 
   On the back face side of the back guide  34 , placed are supporting plates  35  and  36 , ( FIGS. 1 and 8 ) which are disposed between the frames  1   a  and  1   b . Between the supporting plates  35  and  36 , guide blocks  38  and  39  supporting a rack  37 , which engages with a gear  45   a  of a below-described back-guide encoder  45 , are placed, and a rotation rod  42  and guide rods  40  and  41  supporting these members are installed. ( FIG. 5 ) 
   The guide rod  40  is, at both ends thereof, fixed to the supporting plates  35  and  36 , and disposed in a state where the guide rod  40  penetrates the guide block  38 . The guide rod  41  is, at both ends thereof, fixed to the supporting plates  35  and  36 , and disposed in a state where the guide rod  41  penetrates the guide blocks  38  and  39 . The rotation rod  42  is, at both ends thereof, pivotally supported by the supporting plates  35  and  36 . Here, an external thread portion  42   a  is formed in the rotation rod  42 , and engages with an internal thread portion  38   a  formed in a block  38 A which is fixed to the guide block  38 . Moreover, a gear  43  is provided to an end of the rotation rod  42 . ( FIG. 8 ) 
   Below the rotation rod  42 , a back-guide drive motor  44  provided as back-guide moving means, which is supported by the supporting plate  35 , is placed, and a gear  44   a  of the back-guide drive motor  44  and the gear  43  engages with each other. The back-guide encoder  45  is supported by a bracket  68  which is supported by the frame  1   b , and the gear  45   a  of the back-guide encoder  45  and the rack  37  engage with each other. 
   Next, between the supporting plate  35  and the guide block  38 , moving rods  46  and  47  and a fixed rod  48  are disposed. The moving rods  46  and  47  penetrate the supporting plate  35  and the guide block  38 . End portions  46   a  and  47   a  located outside the guide block  38  are formed on one ends of the moving rods  46  and  47 , and connection members  49  and  50  are supported by the other ends thereof. One end of the fixed rod  48  penetrates the supporting plate  35  and is fixed to the guide block  38 , and the other end thereof is supported by a connection member  51 . The moving rods  46  and  47  and the fixed rod  48  support the back guide members  34   a ,  34   b  and  34   c  via the connection members  49 ,  50  and  51 . Each of one ends of the connection members  49 ,  50  and  51  forks and is swingable, so that the angle thereof can be changed. 
   Back-guide rodless air cylinders  52  and  53  provided as back-guide moving means, which are supported on the supporting plates  35  and  36  at both ends thereof, are disposed above the moving rods  46  and  47 . The end portions  46   a  and  47   a  of the moving rods  46  and  47  are fixed to the bottom of moving blocks  52   a  and  53   a  of the back-guide rodless air cylinders  52  and  53 . 
   Moreover, supporting members  54 ,  55  and  56  are installed on the back-side upper portions of the back guide members  34   a ,  34   b  and  34   c , respectively. A supporting shaft  57  is placed in elongated slots  54   a ,  55   a  and  56   a  opening in the supporting members  54 ,  55  and  56 . An arm  59  extended from a supporting plate  58  supports the supporting shaft  57 . 
   Accordingly, with the structure described above, sliding members  8  and  9  slide on the rail  7  as the fan-wheel air cylinders  4  and  5  expand and contract, and the supporting members  10  and  11  slide with this motion, so that the fan wheel members  2   a  and  2   b  can move in the axis direction of the supporting shaft  3 , that is, in the width direction of the signature. ( FIG. 2 ) 
   The side guide  20  is freely slidably supported by the supporting block  24 , which is supported by the frame  1   b , and is thereby movable in the radial direction of the fan wheel  2 . On the other hand, the side guide  21  is movable in the radial direction of the fan wheel  2  by means of the side-guide rodless air cylinder  27 , and is movable in the width direction of the signature by the forward and reverse rotations of the side-guide drive motor  32 . In addition, with the side-guide encoder  33 , it is possible to sense the position of the side guide  21  in the width direction of the signature from the rotational position of the side-guide drive motor  32 . ( FIGS. 4 ,  6  and  9 ). 
   As for the back guide members  34   a ,  34   b  and  34   c , in the case of moving the back guide members  34   a ,  34   b  and  34   c  toward the fan wheel  2 , for example, first, the back-guide drive motor  44  is allowed to rotate, whereby the rotation rod  42  is rotated. The rotation of the rotation rod  42  allows the rack  37  and the guide blocks  38  and  39  to move toward the fan wheel  2 , and allows the fixed rod  48  to move. At the same time, since air is fed to the back-guide rodless air cylinders  52  and  53 , and the moving blocks  52   a  and  53   a  and the end portions  46   a  and  47   a  of the moving rods  46  and  47  are pressed against the guide block  38 , these members also move toward the fan wheel  2 . 
   When the guide block  38  stops in a predetermined position in a state where the end portions  46   a  and  47   a  of the moving blocks  46  and  47  are in contact with the guide block  38 , the movement of the moving blocks  52   a  and  53   a  are restricted. Thus, the moving rods  46  and  47  and the fixed rod  48  are placed in the same position, so that the back guide members  34   a ,  34   b  and  34   c  are also placed in the same position. It is designed to be able to sense the position of the back guide members  34   a ,  34   b  and  34   c  at this time by use of the movement of the rack  37  via the gear  45   a  engaging with the rack  37  and the back-guide encoder  45  coupled with the gear  45   a . ( FIG. 8 ) 
   Under the above described state, in the case of retracting, from the fan wheel  2 , only the back guide members  34   a  and  34   b , this is made possible by feeding air to the back-guide rodless air cylinders  52  and  53  to move the moving blocks  52   a  and  53   a  and the end portions  46   a  and  47   a  of the moving rods  46  and  47  in the direction of the retraction from the fan wheel  2 . Similarly, it is also possible to move only the back guide member  34   a.    
   In the case of retracting the back guide members  34   a ,  34   b  and  34   c  from the fan wheel  2 , since it is merely the reverse operation of the case of moving the back guide members  34   a ,  34   b  and  34   c  toward the fan wheel  2 , the description thereof is omitted. 
     FIG. 10  is a block diagram showing the configuration of a printing press provided with the delivery according to the present embodiment. As shown in  FIG. 10 , a printing press  61  includes a controller  60 . The controller  60  is connected with the fan-wheel air cylinders  4  and  5 ; the side-guide rodless cylinder  27 ; the side-guide drive motor  32 ; the side-guide encoder  33 ; the back-guide drive motor  44 ; the back-guide encoder  45 ; the back-guide rodless air cylinders  52  and  53 ; a printing-press speed detector  62 ; a folding specification input part  63 ; and a display device  64 . 
   When a folding specification is inputted in the folding specification input part  63  by an operator, on the basis of the signal, the controller  60  performs control sequentially so as to drive the side-guide drive motor  32  and the back-guide drive motor  44 , and feed air to the air cylinders  4  and  5 , the side-guide rodless cylinder  27 , and the back-guide rodless air cylinders  52  and  53 . Thus, the fan wheel  2 , the side guide  21  and the back guide  34  are moved to predetermined positions. At this time, the positions of the side guide  21  and the back guide  34  are sensed by the side-guide encoder  33  and the back-guide encoder  45 , respectively, and an operator can view the positions on the display device  64  such as a display. Moreover, on the basis of the signal from the printing-press speed detector  62 , the controller  60  moves the side guide  21  placed in a guide position for a signature in the width direction of the signature in response to the drive speed of the printing press  61 , and suitably guides the signature. 
   Next, a description will be given of a process of the controller  60  in a situation where, in the delivery configured as described above, signatures with different folding specifications are transported by use of  FIGS. 11 to 17 . 
   Here, in the folding machine (not shown) of the printing press  61 , as shown in  FIGS. 4 and 5 , it is possible to select from, for example, three types of folding specifications, the signature  65  which is folded in parallel one time, the signature  66  which is delta-folded, and the signature  67  which is folded in parallel two times. Therefore, the delivery according to the present invention is also capable of supporting all these folding specifications. 
   First, by use of  FIG. 11 , a description will be given of a discrimination process at the time of changing the folding specification. 
   As shown in  FIG. 11 , in step S 1 , a folding specification of any of one-time parallel folding, two-time parallel folding and delta folding is newly inputted to the folding specification input part  63 . In step S 2 , it is determined whether or not the current folding specification is the one-time parallel folding. If the result is Yes, in step S 3 , it is determined whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the one-time parallel folding. Here, if the result is Yes, the process will end. 
   Specifically, since the folding specification in this case is changed from the one-time parallel folding to the one-time parallel folding, the controller  60  does not drive the side-guide drive motor  32  and the back-guide drive motor  44 , and does not allow the fan-wheel air cylinders  4  and  5 , the side-guide rodless cylinder  27 , and back-guide rodless air cylinders  52  and  53  to operate. Therefore, the fan wheel members  2   a  and  2   b  remain placed in the rotation positions R 1  and R 2 , the side guide  21  remains placed in the guide position M 1 ′, and the back guide members  34   a ,  34   b  and  34   c  remain placed in the guide position N 1 . 
   If the result is No in step S 3 , it is determined in step S 4  whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the delta folding. Here, if the result is Yes, the process continues to a process shown in later-described  FIG. 12 . That is, the folding specification in this case is changed from the one-time parallel folding to the delta folding. 
   On the other hand, if the result is No in step S 4 , the process continues to a process shown in later-described  FIG. 13 . That is, the folding specification in this case is changed from the one-time parallel folding to the two-time parallel folding. 
   Moreover, if the result is No in step S 2 , it is determined in step S 5  whether or not the current folding specification is the delta folding. If the result is Yes, it is determined in step S 6  whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the one-time parallel folding. Here, if the result is Yes, the process continues to a process shown in later-described  FIG. 14 . That is, the folding specification in this case is changed from the delta folding to the one-time parallel folding. 
   If the result is No in step S 6 , it is determined in step S 7  whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the delta folding. If the result is Yes, the process will end. 
   Specifically, since the folding specification in this case is changed from the delta folding to the delta folding, the controller  60  does not drive the side-guide drive motor  32  and the back-guide drive motor  44 , and does not allow the fan-wheel air cylinders  4  and  5 , the side-guide rodless cylinder  27 , and back-guide rodless air cylinders  52  and  53  to operate. Therefore, the fan wheel members  2   a  remains placed in the retraction position r 1 , the fan wheel members  2   b  remains placed in the rotation position R 2 , the side guide  21  remains placed in the guide position M 2 ′, the back guide member  34   a  remains placed in the retraction position nil, and the back guide members  34   b  and  34   c  remain placed in the guide position N 1 . 
   On the other hand, if the result is No in step S 7 , the process continues to a process shown in later-described  FIG. 15 . That is, the folding specification in this case is changed from the delta folding to the two-time parallel folding. 
   Moreover, if the result is No in step S 5 , it is determined in step S 8  whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the one-time parallel folding. Here, if the result is Yes, the process continues to a process shown in later-described  FIG. 16 . That is, the folding specification in this case is changed from the two-time parallel folding to the one-time parallel folding. 
   If the result is No in step S 8 , it is determined in step S 9  whether or not the folding specification which is newly inputted to the folding specification input part  63  in step S 1  is the delta folding. If the result is Yes, the process continues to a process shown in later-described  FIG. 17 . That is, the folding specification in this case is changed from the two-time parallel folding to the delta folding. 
   If the result is No in step S 9 , the process will end. Specifically, since the folding specification in this case is changed from the two-time parallel folding to the two-time parallel folding, the controller  60  does not drive the side-guide drive motor  32  and the back-guide drive motor  44 , and does not allow the fan-wheel air cylinders  4  and  5 , the side-guide rodless cylinder  27 , and back-guide rodless air cylinders  52  and  53  to operate. Therefore, the fan wheel members  2   a  and  2   b  remain placed in the retraction positions r 1  and r 2 , the side guide  21  remains placed in the guide position M 3 , the back guide members  34   a  and  34   b  remain placed in the retraction position nil, and the back guide member  34   c  remains placed in the guide position N 1 .

In step SF 8 , it is determined whether or not the side-guide rodless air cylinder  27  has completed extending in the other direction. In other words, it is determined whether or not the side guide  21  has moved from the guide position M 2 ′ to the retraction position m 2 . Here, if the result is Yes, the fan-wheel air cylinder  5  is allowed to operate in one direction in step SF 9 . If the result is No, the detection is continued. 
   In step SF 10 , it is determined whether or not the fan-wheel air cylinder  5  has completed retraction. In other words, it is determined whether or not the fan wheel member  2   b  has moved from the retraction position r 2  to the guide position R 2 . Here, if the result is Yes, the side-guide rodless air cylinder  27  is allowed to operate in one direction in step SF 11 . If the result is No, the detection is continued. In step SF 12 , it is determined whether or not the side-guide rodless air cylinder  27  has completed extending in one direction. In other words, it is determined whether or not the side guide  21  has moved from the retraction position m 2  to the guide position M 2 ′. Here, if the result is Yes, the back-guide drive motor  44  is driven to rotate in one direction in step SF 13 . If the result is No, the detection is continued. 
   In step SF 14 , the back-guide rodless air cylinder  53  is driven to rotate in one direction. In step SF 15 , it is determined whether or not it is detected by the back-guide encoder  45  that the back guide members  34   b  and  34   c  have moved to the guide position N 1 . Here, if the result is Yes, the process will end. If the result is No, the detection is continued. 
   Thus, the above described operations make it possible to easily move the positions in which the fan wheel members  2   a ,  2   b ,  2   c  and  2   d , the back guide members  34   a ,  34   b  and  34   c , and the side guide  21  are placed, even when the fan wheel members  2   a ,  2   b ,  2   c  and  2   d  rotationally transport each of the signatures  65 ,  66  and  67  which have different folding specifications. 
   The side guide  21  placed in the guide positions is designed to be moved by the controller  60  in the width direction of the signatures  65 ,  66  and  67 , that is, between the guide positions M 1 , M 2  and M 3  and the guide positions M 1 ′, M 2 ′ and M 3 ′, respectively, in response to the drive speed of the printing press  61  (the transporting speed of the signature). This is because of the following reasons. When a signature is transported at a low speed, the signature has little momentum, lacks stability, and is thus transported askew. Therefore, when the side guide is placed in accordance with the length in the width direction of the signature, there is a possibility that the signature bumps into the side guide. In order to avoid this, in the delivery according to the present embodiment, at the time when the drive speed is in a range excluding a speed at which the printing press  61  performs printing in normal operation, especially at the time of starting up (200 rpm or less, for example), the side guide  21  is placed with the side guide  21  spaced apart from the guide positions M 1 , M 2  and M 3  to the guide positions M 1 ′, M 2 ′ and M 3 ′ (20 to 80 mm, for example). This prevents the signatures  65 ,  66  and  67  which have been transported from bumping into the side guide  21 , and thereby inhibiting a paper jam and the like from occurring. 
   In addition, the side guide  21  is so designed that the side guide  21  gradually moves from the guide positions M 1 ′, M 2 ′ and M 3 ′ to the guide positions M 1 , M 2  and M 3 , respectively, as the drive speed of the printing press  61  increases, and, when the printing press  61  reaches normal operation, the side guide  21  is eventually placed in the guide position M 1 , M 2  or M 3 . Incidentally, from the time of normal operation to the time of shutting down of the printing press  61 , the side guide  21  may be placed in the guide positions M 1 ′, M 2 ′ and M 3 ′. 
   It should be noted that, while the operation of the printing press  61  is started with the side guide  21  placed in the guide position M 1 ′, M 2 ′ or M 3 ′, and the side guide  21  is moved to the guide position M 1 , M 2  or M 3  at the time of normal operation in the present embodiment as described above, the side guide  21  may be placed in the guide place M 1 , M 2  or M 3  from before starting up the printing press  61 . 
   Here, as another embodiment, the back guide members  34   a ,  34   b  and  34   c  placed in the guide position N 1  may be designed to be moved in the longitudinal direction of the signatures  65 ,  66  and  67 , that is, between the guide position N 1  and the retraction position n 1 , in response to the drive speed of the printing press  61  by the controller  60 . This is because of the following reasons. When a signature is transported at a low speed, the signature has little momentum, lacks stability, and is thus transported askew. Therefore, when the back guide is placed in accordance with the length in the longitudinal direction of the signature, there is a possibility that the signature bumps into the back guide. In order to avoid this, in the delivery according to the present embodiment, at the time when the drive speed is in a range excluding a speed at which the printing press  61  performs printing in normal operation, especially at the time of starting up (200 rpm or less, for example), the back guide members  34   a ,  34   b  and  34   c  are placed with the back guide members  34   a ,  34   b  and  34   c  spaced apart from the guide position N 1  to the retraction position n 1  (20 to 80 mm, for example). This prevents the signatures  65 ,  66  and  67  which have been transported from bumping into the back guide members  34   a ,  34   b  and  34   c , and thereby preventing a paper jam and the like from occurring. 
   In addition, the back guide members  34   a ,  34   b  and  34   c  are so designed that the back guide members  34   a ,  34   b  and  34   c  gradually move from the retraction position n 1  to the guide position N 1  as the drive speed of the printing press  61  increases, and, when the printing press  61  reaches normal operation, the back guide members  34   a ,  34   b  and  34   c  are eventually placed in the guide position N 1 . Incidentally, the back guide members  34   a ,  34   b  and  34   c  are designed to move from the guide position N 1  to the retraction position n 1 , from the time of normal operation to the time of shutting down of the printing press  61 . 
   Thus, with the delivery according to the present invention, since the delivery includes: the fan wheel members  2   a ,  2   b ,  2   c  and  2   d  for holding and rotationally transporting the signatures  65 ,  66  and  67  delivered from the printing press  61 ; the pair of side guides  20  and  21  for restricting the signatures  65 ,  66  and  67  in the width direction which are held in the fan wheel members  2   a ,  2   b ,  2   c  and  2   d ; the side-guide rodless air cylinder  27  for moving at least one side guide  21  between the side-guide guide positions M 1 , M 2 , M 3 , M 1 ′, M 2 ′ and M 3 ′ for guiding the signatures  65 ,  66  and  67  and the side-guide retraction positions m 1  and m 2  for retraction to the outside of the fan wheel members  2   a ,  2   b ,  2   c  and  2   d  in the radial direction thereof; the side-guide drive motor  32  for moving at least one side guide  21  in the width direction of the signatures  65 ,  66  and  67 ; and the controller  60  which controls the side-guide rodless air cylinder  27  and the side-guide drive motor  32  so that the side guide  21  moves in accordance with the lengths in the width direction of the signatures  65 ,  66  and  67 , it is possible to automatically move the side guide  21  at the time of changing the folding specification. 
   Moreover, since the retraction positions m 1  and m 2  are placed outside the peripheries of the fan wheel members  2   a ,  2   b ,  2   c  and  2   d , it is possible to prevent the side guide  21  from coming into contact with the fan wheel members  2   a ,  2   b ,  2   c  and  2   d  even when the side guide  21  moves between the retraction positions m 1  and m 2 . 
   Moreover, since the rodless air cylinder  27  for moving the signatures  65 ,  66  and  67  in the transporting direction is supported by the supporting plate  28  which is moved by the side-guide drive motor  32  in the paper width direction which is the direction orthogonal to the transporting direction, and the supporting plate  28  is supported by the frame  1   a  via the supporting block  29 , it is possible to easily control the side guide  21 .

   Moreover, since the controller  60  moves the side guide  21  to the retraction position m 1  or m 2  after moving the back guide member  34   a ,  34   b  and  34   c  to the retraction position n 1 , and the controller  60  moves the back guide members  34   a ,  34   b  and  34   c  to the guide position N 1  after moving the side guide  21  to the guide position M 1 , M 2 , M 3 , M 1 ′, M 2 ′ or M 3 ′, it is possible to prevent the side guide  21  from coming into contact with the back guide members  34   a ,  34   b  and  34   c.    
   Moreover, since the controller  60  moves the side guide  21  to the retraction position m 1  or m 2  after moving the back guide members  34   a ,  34   b  and  34   c  to the retraction position n 1 , and then moves the side guide  21  to the guide position M 1 , M 2 , M 3 , M 1 ′, M 2 ′ or M 3 ′, it is possible to prevent the side guide  21  from coming into contact with the back guide members  34   a ,  34   b  and  34   c.    
   Moreover, since the back-guide drive motor  44  and the back-guide rodless air cylinders  52  and  53  are provided, it is possible to easily move the back guide members  34   a ,  34   b  and  34   c  to the guide position N 1  and the retraction position n 1  in accordance with the length in the width direction of the signatures  65 ,  66  and  67 . 
   Moreover, since the back guide member  34   c  is fixed to the guide block  38 , and the back guide members  34   b  and  34   c  are inserted into the guide block  38  in such a manner that the forward movement of the back guide members  34   b  and  34   c  is restricted, it is possible to easily control the back guide members  34   a ,  34   b  and  34   c.    
   Moreover, since the back guide members  34   a ,  34   b  and  34   c  are moved between the guide position N 1  and the retraction position n 1  by use of the movement of the guide block  38 , it is possible to easily control the back guide members  34   a ,  34   b  and  34   c  in a simple configuration. 
   Moreover, since the other side guide  20  is fixed near the back guide member  34   c , it is possible to stably guide one end of the signature  65 ,  66  or  67 . 
   Moreover, since the fan-wheel members  2   a  and  2   b  are supported freely movably in the width direction of the signatures  65 ,  66  and  67 , it is possible to automatically move the fan wheel members  2   a  and  2   b  at the time of changing the folding specification. 
   Moreover, since the fan-wheel air cylinders  4  and  5 , which move the fan wheel members  2   a  and  2   b  in the width direction of the signatures  65 ,  66  and  67 , are provided, it is possible to easily control the fan wheel members  2   a  and  2   b.    
   Moreover, since the controller  60  moves the back guide members  34   a ,  34   b  and  34   c  to the retraction position n 1 , moves the side guide  21  to the retraction position m 1  or m 2 , moves the fan wheel members  2   a  and  2   b  to a position corresponding to the signature  65 ,  66  or  67 , moves the side guide  21  to the guide position M 1 , M 2 , M 3 , M 1 ′, M 2 ′ or M 3 ′, and then moves the back guide members  34   a ,  34   b  and  34   c  to the guide position N 1 , it is possible to easily control the fan wheel members  2   a  and  2   b , side guide  21 , and the back guide members  34   a ,  34   b  and  34   c  and to prevent the contact thereof with another at the time of changing the folding specification. 
   In addition, since it is possible to preserve an appropriate amount of clearance by moving the side guide  21  between the guide positions M 1 , M 2  and M 3  and the guide positions M 1 ′, M 2 ′ and M 3 ′, respectively, in accordance with the drive speed of the printing press  61 , it is possible to prevent the signatures  65 ,  66  and  67  from bumping into the side guide  21 . In particular, at the time of starting up the printing press, even if the signatures  65 ,  66  and  67  are transported askew, it is possible to surely prevent the signatures  65 ,  66  and  67  from bumping into the side guide  21  because the side guide  21  is placed in the guide position M 1 ′, M 2 ′ or M 3 ′. 
   Moreover, since it is possible to preserve an appropriate amount of clearance by moving the back guide members  34   a ,  34   b  and  34   c  between the guide position N 1  and the retraction position n 1  in accordance with the drive speed of the printing press  61 , it is possible to prevent the signatures  65 ,  66  and  67  from bumping into the back guide members  34   a ,  34   b  and  34   c . In particular, at the time of starting up the printing press, even if the signatures  65 ,  66  and  67  are transported askew, it is possible to surely prevent the signatures  65 ,  66  and  67  from bumping into the back guide members  34   a ,  34   b  and  34   c  because the back guide members  34   a ,  34   b  and  34   c  are placed in the retraction position n 1 . 
   Thus, such automation improves the workability of the position adjustment of the fan wheel members  2   a  and  2   b , the side guide  21 , and the back guide members  34   a ,  34   b  and  34   c  by an operator, and eliminates the attachment failure, thereby preventing a paper jam of the signature. 
   It should be noted that the side guide  20  may be provided with an air cylinder, a drive motor and the like, so that the side guide  20  is allowed to be able to move in the radial direction of the fan wheel  2  or in the width direction of the signatures  65 ,  66  and  67  as in the case of the side guide  21 .
