The diameter, the number of teeth, and the like are set, and the conveyor belt 23 of the discharge conveyor 20 runs at a conveyance speed that is substantially the same as the outer peripheral speed of the rotary stripper 134.

  The sawtooth pressing portion 134a of the rotary stripper 134 is inclined so that the downstream side in the rotation direction (clockwise in FIG. 1) intersects the radial direction from the axis S2 serving as the rotation center. It is a pressing surface 134aa and holds the signature 1 by sandwiching the leading direction side of the signature 1 that has entered the space 112b of the blade 112 in cooperation with the blade 112a of the blade 112.

See), in other words, the vane plate 11 The blade 112 and the position shifted from the position symmetrical with respect to the center line of the signature 1 received in the interval 112b to the side opposite to the crease due to the parallel folding of the signature 1 While the drive motor 156 is controlled so that the brake guide 121 and the discharge conveyor 20 are positioned, the folding specification of the inputted signature 1 is delta folding (triangular folding: see FIG. 5B) or parallel double diffraction ( 2) (see FIG. 5C), the signature 1 that is received in the gap 112b of the blade plate 112 protrudes outward from the blade plate 112 positioned on both ends in the axial direction of the rotary shaft 111. , Positions where the lengths L3, L4 on both ends 1c, 1d side having parallel folds are made substantially equal, that is, positions where the center position Cw substantially matches the center position Cs. 6B and 6C), in other words, the vane plate 112, the brake guide 121, and the discharge at a position symmetrical with respect to the center line of the signature 1 received in the gap 112b of the vane plate 112. The drive motor 156 is controlled to position the conveyor 20.

  In the following description, the folding specification of the signature 1 is folded in parallel, that is, parallel folding is performed only on one end side in the width direction of the signature 1 entering the space 112b of the blade 112. A case where a fold specification having a fold is selected will be described.

  Subsequently, the signature 1 obtained by subjecting the web printed by the rotary printing press to the former folding and cutting by the folding machine and parallel diffracting is conveyed along the guide table 11 by the conveying belt 12 of the chopper folding device 10. When positioned on the slit 11a, the chopper blade 13 swings and is dropped downward from the slit 11a of the guide table 11 and vertically folded between the folding rollers 14 (see FIG. 5A). It is conveyed and sent downward from between the lowermost guide rollers 16 (see FIG. 7).

  The signature 1 fed downward from between the guide rollers 16 has a length L1 on the end 1a side (bag side) longer than a length L2 on the end 1b side (peller side) by a predetermined length. That is, in other words, the center position Cs is positioned closer to the end 1a side (bag side) than the center position Cw (see FIG. 6A). ) (See FIG. 8), enters toward the bottom of the interval 112b, and the tip contacts the brake surface 121b of the brake guide 121 (see FIG. 9).

  The signature 1 in contact with the brake surface 121b of the brake guide 121 further enters the space 112b of the rotating blade plate 112, and the blade 112a of the blade plate 112 and the brake guide 121 By the cooperation with the brake surface 121b, it is sequentially bent along the approach direction so as to form a wave shape in the width direction (the vertical direction in FIG. 10, the left-right direction in FIG. 11) (see FIGS. 10 and 11). .

  As a result, the signature 1 gradually receives resistance from the vane plate 112 and the brake guide 121, so that the entry speed is reduced without damaging the tip side.

  Further, when the approach speed is reduced by the cooperation of the blade 112a of the blade plate 112 and the brake surface 121b of the brake guide 121, the signature 1 is on the end 1b side (peller side). Since the length L1 on the end 1a side (bag side) is longer than the length L2 by a predetermined length (L1> L2), entry delay due to large resistance on the end 1a side (bag side) is reduced. The influence is greatly avoided, and the end portion 1a side (bag side) and the end portion 1b side (peller side) enter the space 112b of the blade plate 112 toward the bottom portion at substantially the same speed. It becomes like this.

  In this way, while the signature 1 receives resistance from the slats 112 and the brake guide 121, the signature 1 further enters the interval 112b of the rotating slats 112 toward the bottom at substantially the same speed in the width direction. Then (see FIG. 12), the signature 1 has its tip side substantially simultaneously inserted in the width direction between the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 and the interval 112b (blade 112a). In the meantime, it enters without bending in the transport direction (see FIG. 13).

  In the signature 1 that has entered between the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 and the interval 112b (blade 112a), the rotational speed of the rotary stripper 134 is higher than the rotational speed of the blade plate 112. Therefore, the tip side is gradually sandwiched and held by the cooperation of the blade 112a of the blade 112 and the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134, and the blade 112 With further rotation, the brake guide 121 gradually separates from the brake surface 121b (see FIGS. 14 to 16).

  At this time, the signature 1 is held between the blade 112a of the blade plate 112 and the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 at the front end side. Even if the surface 121b is separated, the direction of the vane plate 112 in the interval 112b is not shifted.

  Subsequently, when the blade 112 and the rotary stripper 134 further rotate, the signature 1 falls onto the conveyor belt 23 of the discharge conveyor 20 while the rear end side is guided by the guide member 109. (See FIG. 17).

  At this time, as described above, the signature 1 is sandwiched and held between the blade 112a of the blade 112 and the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 as described above. Therefore, even if the rear end of the discharge conveyor 20 lands on the conveyor belt 23 and receives an impact, the direction does not deviate.

  Further, the signature 1 has its tip side substantially simultaneously inserted in the width direction between the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 and the interval 112b (blade 112a) of the blade plate 112, that is, Since it is held without being bent with respect to the transport direction during this time, it is transferred onto the conveyor 23 of the discharge conveyor 20 without being bent with respect to the transport direction.

  As the vane plate 112 and the rotary stripper 134 further rotate in this manner, the signature 1 gradually increases in the landing area of the discharge conveyor 20 on the conveyor belt 23 (see FIG. 18). ) When most of the landing on the conveyor belt 23, the rotational speed of the rotary stripper 134 is slower than the rotational speed of the blade 112, and the axis S2 of the rotary stripper 134 is 112, which is located downstream of the axis S1 of the rotating shaft 111 in the transport direction of the discharge conveyor 20, that is, the signature than the position of the interval 112b of the blade 112 when the signature 1 is received. Eccentric with respect to the axis S1 of the rotating shaft 111 so as to be positioned on the position side of the interval 112b of the blade 112 when the 1 is sent out Therefore, the signature 1 is released from the pinching due to the cooperation between the blade 112a of the blade plate 112 and the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134, and onto the conveyor belt 23. It lands over the entire length, is completely delivered to the discharge conveyor 20 and discharged (see FIG. 19).

  At this time, most of the signature 1 lands on the conveyor belt 23 of the discharge conveyor 20, and then the pressing surface of the pressing portion 134 a of the blade 112 a of the blade plate 112 and the rotary stripper 134. Since it is released from the holding by 134aa, the impact applied along with the landing is reduced, and the rebound on the conveyor belt 23 is greatly suppressed.

  Then, after finishing the folding specification of such parallel one-fold, for example, delta folding (see FIG. 5B) or parallel two-folding (see FIG. 5C), that is, the blade 112 enters the space 112b. When a folding specification having parallel folds on both ends in the width direction of the signature 1 is selected, in other words, when a folding specification having the same folding state on one side and the other side in the width direction of the signature 1 is selected, As described above, the control device 180 protrudes outward from the blade plate 112 positioned on both ends of the rotary shaft 111 in the axial direction of the signature 1 that is received in the gap 112b of the blade plate 112. The positions where the lengths L3 and L4 on both ends 1c and 1d side having parallel folds are made substantially equal, that is, the position where the center position Cw substantially matches the center position Cs (see FIGS. 6B and 6C). ), In other words, the blade plate 112, the brake guide 121, and the discharge conveyor 20 are positioned in a line-symmetrical position with respect to the center line of the signature 1 received in the gap 112b of the blade plate 112. In addition to controlling the drive motor 156, the circumferential direction (rotation direction) of the blade plate 112 corresponding to the thickness of the signature 1 in the folding specification, that is, the thickness larger than the parallel folding signature 1 ), Specifically, the position of the brake guide at a position upstream of the vane plate 112 in the rotational direction (counterclockwise direction in FIG. 1) with respect to the previously set position of parallel diffraction. The position of the brake guide 121 is confirmed based on the information from the rotary encoder 163 so that the brake surface 121b of 121 is positioned (see FIGS. 20 and 22). While, controls the drive motor 127 based on pre-input information.

  As a result, the above-described signature 1 of delta folding or parallel two-folding that has entered the space 112b of the slat 112 is the same as that of the parallel one-folding described above. In contact with the surface 121b, the blade 112 further enters the space 112b of the rotating blade plate 112, and the width of the blade 112a by the cooperation of the blade 112a of the blade plate 112 and the brake surface 121b of the brake guide 121 It is bent sequentially in the approach direction so as to form a wave shape in the direction (left and right in FIGS. 21 and 23) (see FIGS. 21 and 23), and gradually receives resistance from the blade plate 112 and the brake guide 121. It becomes like this.

  At this time, the brake surface 121b of the brake guide 121 corresponds to the thickness of the signature 1 in the folding specification of delta folding or parallel folding, that is, thicker than the signature 1 of parallel folding. The position of the blade 112 in the rotational direction upstream of the previously set position at the time of parallel diffraction, that is, the bending state of the signature 1 is made smaller than that at the time of parallel diffraction. Therefore, even in the case of a delta-folded or parallel-folded signature 1 having a thickness greater than that of the parallel one-fold signature 1, the entry speed can be reduced without damaging the tip side. Can do.

  Further, the signature 1 enters the space 112b of the blade 112, and the approach speed is reduced by the cooperation of the blade 112a of the blade 112 and the brake surface 121b of the brake guide 121. In this case, the lengths L3 and L4 on both the end portions 1c and 1d projecting outward from the vane plate 112 positioned on both ends in the axial direction of the rotating shaft 111 are made substantially equal (FIG. 21). , See FIG. 23), the signature 1 having parallel folds at both ends, that is, the signature 1 having substantially the same resistance at both ends, has a substantially equal speed toward the bottom within the space 112b of the blade 112. It will come in.

  For this reason, as in the case of the parallel folding, the signature 1 has a tip side between the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 and the interval 112b (blade 112a) of the blade plate 112. Since it enters in the width direction at the same time, that is, enters and is held without being bent with respect to the conveying direction in the meantime, it is not bent with respect to the conveying direction on the conveyor 23 of the discharge conveyor 20. It will be transferred.

  On the other hand, when the folding specification of the delta folding or the parallel two-folding is finished and the initial parallel one-folding is selected again, the control device 180, as explained above, The length L1 on the end 1a side (bag side) of the signature 1 received at the interval 112b is made longer than the length L2 on the end 1b side (peller side) by a preset length (L1). > L2) The position, that is, the position where the center position Cw is closer to the end 1b side (peller side) than the center position Cs (see FIG. 6A), in other words, is received by the gap 112b of the vane plate 112. The vane plate 112, the brake guide 121, and the discharge at a position shifted from a position symmetrical with respect to the center line of the signature 1 to a side opposite to the crease side due to the parallel folding of the signature 1. Conveyor 20 The vane plate that controls the drive motor 156 so as to be positioned and corresponds to the thickness of the signature 1 in the folding specification, that is, the thickness smaller than the signature 1 of delta folding or parallel two-folding. The position in the circumferential direction (rotation direction) of 112, specifically, the downstream side in the rotation direction of the blade 112 relative to the previously set position for delta folding or parallel two-folding (in FIG. While confirming the position of the brake guide 121 based on the information from the rotary encoder 163 so that the brake surface 121b of the brake guide 121 is positioned at a position in the rotation direction (see FIGS. 7 and 9, etc.) The drive motor 127 is controlled based on information inputted in advance.

  Thereby, the impeller apparatus 100 can be easily switched to the signature 1 with the original parallel folding pattern, and can handle the signature 1 that has been lowered once in parallel as described above.

  Next, after the handling as described above, for example, when handling a signature 1 (such as a long web) whose length in the transport direction is longer than the previous setting due to a change in the web, that is, When the timing of the signature 1 that starts to enter the space 112b of the blade 112 is later than the previously set condition (web width), the new condition (web width) is changed to the operation. When the control device 180 is input again to the panel 181, the control device 180 causes the position (in the rotational direction) of the blade plate 112 corresponding to the newly input condition (more than the previously set position). Based on the information from the rotary encoder 163 so that the brake surface 121b of the brake guide 121 is positioned on the upstream side in the rotation direction of the blade 112 (counterclockwise direction in FIG. 1). While checking the position of the brake guide 121, and controls the drive motor 127 based on pre-input information.

  Thereby, the brake surface 121b of the brake guide 121 having an arc shape with substantially the same curvature as the surface of the blade 112a in the rotation direction of the blade 112a is positioned at a predetermined position corresponding to the above condition. Since the brake guide 121 moves in an arc shape centering on the axis S1 of the rotating shaft 111 of the vane plate 112 so that the distance between the brake surface 121b of the brake guide 121 and the vane plate 112 is 112b. And the folding surface 121b of the brake guide 121 after the signature 1 has entered the space 112b of the blade 112, and the folding position. The contact timing with Ding 1 can be advanced.

  For this reason, the length in the conveyance direction of the signature 1 is longer than the previous setting, that is, the timing of the signature 1 that starts to enter the space 112b of the blade 112 is earlier than in the previous setting. Even if it becomes late, since the approach speed of the said signature 1 can be decelerated reliably, it can handle similarly to the case of the signature 1 of the length of the conveyance direction set previously.

  On the other hand, when handling a signature 1 (a web having a short width) whose length in the transport direction is shorter than the previous setting due to a change in the web or the like, that is, a folding that starts to enter the space 112b of the blade 112. When the timing of Ding 1 becomes earlier than the previously set condition (web width), a new condition (web width) is input again to the operation panel 181, whereby the control device 180. Is a position in the circumferential direction (rotation direction) of the slat 112 corresponding to the new condition newly input (in the rotational direction downstream side of the slat 112 relative to the previously set position (in FIG. 1, While confirming the position of the brake guide 121 based on the information from the rotary encoder 163 so that the brake surface 121b of the brake guide 121 is positioned in the clockwise direction)) It controls the drive motor 127 based on pre-input information.

  Thereby, the brake surface 121b of the brake guide 121 having an arc shape with substantially the same curvature as the surface of the blade 112a in the rotation direction of the blade 112a is positioned at a predetermined position corresponding to the above condition. Since the brake guide 121 moves in an arc shape centering on the axis S1 of the rotating shaft 111 of the vane plate 112 so that the distance between the brake surface 121b of the brake guide 121 and the vane plate 112 is 112b. And the folding surface 121b of the brake guide 121 after the signature 1 has entered the space 112b of the blade 112, and the folding position. The contact timing with Ding 1 can be delayed.

  For this reason, the length in the conveyance direction of the signature 1 is shorter than the previous setting, that is, the timing of the signature 1 that starts to enter the space 112b of the blade 112 is earlier than in the previous setting. Even if it becomes faster, the leading end side of the signature 1 can reach the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 without stopping in the middle of the interval 112b of the blade 112. The approach speed of the signature 1 can be reduced until the signature 1 can be handled in the same manner as in the case of the signature 1 having a length in the transport direction that has been previously set.

  After the handling of the signature 1 as described above is finished in this way, for example, when performing a maintenance check around the interval 112b of the impeller 112 of the impeller device 100, the operator can handle the handle. 105, the frame 103 is pulled out along the guide rail 101, and the frame 103 is transported from the upstream side position (operating position of the impeller device 100) in the transport direction (discharge direction) of the discharge conveyor 20 ( Displacement direction) By moving to a downstream position (retracted position of the impeller device 100), a large space is formed around the gap 112b of the impeller device 112 of the impeller device 100, and maintenance inspection is performed using the space. Work can be carried out.

  Therefore, according to the impeller device 100 according to the present embodiment, the following effects can be obtained.

(1) Due to the cooperation of the blade 112a of the blade plate 112 and the brake surface 121b of the brake guide 121, the approach direction so as to corrugate in the width direction with respect to the signature 1 entering the space 112b of the blade plate 112. Since the resistance is provided by bending sequentially over the entire length, the entry speed of the signature 1 can be reduced without damaging the leading end side of the signature 1, so that the blade 112 enters the interval 112b. Even if the entry speed of the signature 1 is high, it is possible to prevent the signature 1 from colliding with the bottom of the interval 112b and bounce-back, and the signature 1 is transferred to the discharge conveyor 20 while being aligned. Can do.

(2) Since the brake surface 121b of the brake guide 121 has an arc shape having substantially the same curvature as the surface of the blade 112 in the rotation direction of the blade 112a, the blade 112a of the blade 112 and the brake surface of the brake guide 121 Since the shape of the waveform of the folded signature 1 can be made substantially uniform in the approach direction of the signature 1 by cooperating with 121b, the braking force by the blade 112 and the brake guide 121 is applied to the signature 1. The direction can be made substantially uniform, and the approach speed can be efficiently reduced while suppressing damage to the signature 1.

(3) Since the brake guide 121 can be moved in an arc shape centering on the axis S1 of the rotating shaft 111 of the blade plate 112, the relative relationship between the brake surface 121b of the brake guide 121 and the interval 112b of the blade plate 112 The contact timing between the brake surface 121b of the brake guide 121 and the signature 1 after the signature 1 has entered the space 112b of the blade 112 can be changed while maintaining the correct position. Even if the folding specifications of the signature 1 are changed, the brake can always be applied under the same conditions. For this reason, since only the single-shaped brake guide 121 can cope with various folding specifications, the number of parts around the blade plate 112 can be reduced, and maintenance and inspection can be facilitated and the cost can be reduced. be able to.

(4) Since the front end side of the signature 1 is inserted between the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134 and the blade 112a (the interval 112b) of the blade plate 112, the blade plate 112 is sandwiched between them. Even if the speed of entry of the signature 1 into the interval 112b is high, the signature 1 can be prevented from colliding with the bottom of the interval 112b and bounced back, and the signature 1 is aligned on the discharge conveyor 20. Can be transferred.

(5) The rotational speed of the rotary stripper 134 is slower than the rotational speed of the vane plate 112, and the axis S2 of the rotary stripper 134 is downstream of the axis S1 of the rotary shaft 111 of the vane plate 112 in the conveying direction of the discharge conveyor 20. In other words, it is positioned closer to the position of the interval 112b of the blade 112 when the signature 1 is sent out than the position of the interval 112b of the blade 112 when the signature 1 is received. Since it is eccentric with respect to the axis S1 of the rotary shaft 111, the front end side of the signature 1 is held between the blade 112a of the blade plate 112 and the pressing surface 134aa of the pressing portion 134a of the rotary stripper 134. Since the rear end side of the signature 1 can be landed on the conveyor belt 23 of the discharge conveyor 20, the jump when the landing is made on the conveyor belt 23. The shift of the signature 1 due to the return can be prevented, and the majority of the signature 1 is landed on the conveyor belt 23, and then the pressing surface of the blade 112 a of the blade plate 112 and the pressing portion 134 a of the rotary stripper 134. Since it is possible to release the signature 1 in cooperation with 134aa, it is possible to reduce the impact applied to the signature 1 upon landing and greatly rebound the signature 1 on the conveyor belt 23. Can be reduced.

(6) When the folding specification of the signature 1 is one-fold in parallel, that is, the folds of the parallel folding are made only on one end side in the width direction of the signature 1 entering the space 112b of the blade 112. When the folding specification has, in other words, when the folding state is different between the one side and the other side in the width direction of the signature 1, the center line of the signature 1 that is received by the interval 112b of the blade 112 is used. By rotating the vane plate 112, the brake guide 121, and the discharge conveyor 20 at a position shifted from a line-symmetrical position to a side opposite to the crease side due to the parallel folding of the signature 1, the rotation is performed. The end portion 1a side (bag) protruding from the blade plate 112 outward in the axial direction of the rotating shaft 111 rather than the length L2 of the signature 1 on the end portion 1b side (peller side) protruding outward in the axial direction of the shaft 111. Side) signature 1 length Since the signature 1 is inserted into the interval 112b of the slat 112 so that 1 becomes longer by a predetermined length, the signature is obtained by cooperation between the wing 112a of the slat 112 and the brake surface 121b of the brake guide 121. When the entry speed of 1 is reduced, the influence of the entry delay on the bag side of the signature 1 can be largely avoided, and the bag side and the peller side of the signature 1 are separated from each other by a distance 112b between the blades 112. Since it can be made to approach at the substantially same speed toward the bottom, the deviation of the posture of the signature 1 within the interval 112b of the slats 112 can be greatly suppressed, and the conveyor 23 of the discharge conveyor 20 is moved onto the conveyor 23. Can be transferred with good posture. For this reason, since the guide plate conventionally provided around the discharge conveyor 20 can be omitted, it is possible to easily cope with a change in the folding specification of the signature 1, and to reduce costs, perform maintenance, etc. Can be facilitated.

(7) Since the impeller device 100 can be moved between the operating position and the retracted position, the impeller is used when performing maintenance and inspection work such as the interval 112b of the impeller plate 112 of the impeller device 100. Since a large space can be formed around the interval 112b of the blades 112 of the apparatus 100, maintenance and inspection work can be facilitated.

(8) Move the impeller device 100 from the upstream position (operating position) in the transport direction (discharge direction) of the discharge conveyor 20 to the downstream position (retreat position) in the transport direction (discharge direction), that is, the frame 1000 of the folding machine Since a large space can be formed around the interval 112b of the blades 112 of the impeller device 100 by moving from the inside to the outside, when the impeller device 100 is moved, the space above the discharge conveyor 20 is empty. In other words, it is not necessary to secure a space for moving the impeller device 100, so that the maintenance and inspection work can be facilitated and the space required for installation can be reduced. Can be achieved.

In the above-described embodiment, the control device 180 determines that the above condition is based on information input in advance from various conditions such as the width of the web input from the operation panel 181 and the folding specifications of the signature 1. The drive motor 127 is controlled so that the brake surface 121b of the brake guide 121 is positioned at a position in the circumferential direction (rotation direction) of the blade plate 112 corresponding to The drive motor 156 is disposed so that the blade plate 112, the brake guide 121, and the discharge conveyor 20 are positioned at a position in the axial direction of the folding roller 14, that is, a position in the axial direction of the rotating shaft 111. In another embodiment, for example, the vane plate 112 is moved in the circumferential direction (rotation direction) at an arbitrary distance. The control device 180 controls the drive motor 127 so that the brake position adjustment manual switch, the vane plate 112, the brake guide 121, and the discharge conveyor 20 are arranged at an arbitrary distance in the axial direction of the rotary shaft 111. A manual switch or the like for adjusting the signature center position for controlling the drive motor 156 by the control device 180 is provided on the operation panel 181 so as to be moved by the control device 180. In addition to the above control, it is also possible to perform the control in the manual mode.

  In the above-described embodiment, the frame 103 is moved from the upstream position (operating position of the impeller device 100) in the transport direction (discharge direction) of the discharge conveyor 20 to the downstream position (impeller device) in the transport direction (discharge direction). 100), a large space is formed around the gap 112b of the vane plate 112 of the impeller device 100 and the like so that maintenance and inspection work can be easily performed. As an embodiment of the present invention, for example, by allowing the frame 103 to pivot about a vertical axis, the frame 103 can be moved from the inside to the outside of the folding machine frame 1000, and the distance between the blade plates 112 of the impeller device 100 can be reduced. It is also possible to form a large space around 112b or the like so that maintenance and inspection work can be easily performed.

  In the above-described embodiment, both the vane plate 112 and the brake guide 121 are moved along the axial direction of the rotating shaft 111 according to the folding specifications of the signature 1.
