When the connection shaft 543 is rotated via the screw 45, the action of the screw thread 543 a of the connection shaft 543 and the screw hole 544 a of the holding block 544 causes the drive shaft 5
40 slides along the axial direction, and the helical gears 541 and 542 also slide along the axial direction, so that the helical gears 513 and 514 that mesh with the helical gears 541 and 542 are moved. The relative phase can be adjusted, and the relative phase between the grip shafts 53 and 54 and the second knife shaft 52 can be adjusted (lap amount adjustment).

The gripper cylinder 50 and the second gripper cylinder 60 on the downstream side are rotated so that they can rotate in synchronization with each other as shown in FIG.
As shown in FIG. 4, the helical gear 513 of the gripper cylinder 50
Helical gear 613 for driving and rotating the second gripper cylinder 60
When the lap amount is adjusted as described above, the second gripper cylinder 60 also rotates in the circumferential direction in conjunction with the lap amount, and the knife shaft 52 of the gripper 50 on the side of the entire folding section 10 where the lap amount is adjusted. The relative phase between the knife 52a and the holding plate 61a of the holding shaft 61 of the second holding cylinder 60 is also adjusted at the same time.

At this time, the holding cylinder 50 on the side of the propeller folded portion 20 is formed.
Since the relative phases of the gripper plate 53a of the gripper shaft 53 and the pawl 62a of the pawl shaft 62 of the second gripper cylinder 60 are shifted, the entire folding section 10 in which the wrap amount is adjusted is set.
When switching the folding process from the side to the propeller folded portion 20 side, the gripper plate 53a of the gripper shaft 53 of the gripper cylinder 50 of the propeller folded portion 20 side and the claw 62a of the claw shaft 62 of the second gripper cylinder 60 are provided.
It is necessary to return the lap amount adjustment state to the initial reference state so as to match the relative phase with the above, which is a very time-consuming operation.

For this reason, in the present folding machine, in conjunction with the switching of the folding process between the full-size folding section 10 and the propeller folding section 20, the gripping cylinder 50 and the second gripping cylinder 60 on the side performing the folding process are connected. The relative phase can be switched automatically.

More specifically, as shown in FIGS.
A gear 548 of a potentiometer 549 supported on the frame 1 meshes with the driven gear 545. The potentiometer 549 is electrically connected to a control device 550, and the control device 550 is electrically connected to the motor 547. The control device 550 includes the holding cylinder 5
The actuator 56 of the brush guide 55 (see FIG. 2), which is a guide member that can approach and separate from the outer peripheral surface of the entire folding section 10 side, is electrically connected. This brush guide 55 is close to the outer peripheral surface of the grip cylinder 50 to guide the signature when performing the folding process in the all-folding section 10.
When the folding process is performed by the fold part 20, it is separated from the outer peripheral surface of the gripping cylinder 50 to prevent damage due to abrasion. The control device 550 is provided with an attachment / detachment switch serving as a guide member attachment / detachment selection means for selecting attachment / detachment of the brush guide 55 to / from the holding drum 50. In this embodiment, the folding specification selecting means is constituted by a detachable switch or the like, and the gear 546, the potentiometer 5
49, a control device 550, and the like constitute control means.

The holding shaft 6 having a holding plate 61a is provided.
1 is provided only on the entire folding section 10 side, and two pawl shafts 62 having pawls 62a are provided only on the propeller folding section 20 side and are arranged at equal intervals in the circumferential direction. Also, in FIG.
601 is a central shaft, 615 is a cam attached to the frame 1 side of the entire folding part 10, 616 is a cam follower connected to the gripping shaft 61 and slidingly contacting the cam 615, 623 is attached to the frame 1 side of the propeller folded part 20. CAM, 617
Is a cam follower connected to the pawl shaft 62 and in sliding contact with the cam 623.

Therefore, for example, when the folding process is switched from the all-folded portion 10 to the perforated portion 20, a command to operate the actuator 56 to separate the brush guide 55 from the holding cylinder 50 is input to the control device 550. (When the brush guide attachment / detachment switch is set to “OFF”), the control device 550 operates the actuator 56 so as to separate the brush guide 55 from the holding cylinder 50, and checks the motor while checking the signal from the potentiometer 549. By rotating 547 a predetermined amount,
The relative phase is set by moving the gripping cylinder 50 and the second gripping cylinder 60 to the reference position on the side of the prop folding unit 20. Note that the lap adjustment cannot be performed on the side of the prop-folding section 20. If the lap adjustment is performed by mistake, the knife is interlocked so as not to move.

On the other hand, when the folding process is switched from the perforated portion 20 to the all-folded portion 10, a command for operating the actuator 56 so as to bring the brush guide 55 into contact with the drum 50 is input to the control device 550 ( When the attachment / detachment switch of the brush guide is turned on, the control device 550
Operates the actuator 56 so as to bring the brush guide 55 into contact with the holding cylinder 50, and rotates the motor 547 by a predetermined amount while checking with a signal from the potentiometer 549. The relative phase is set by moving the holding cylinder 50 and the second holding cylinder 60 to the reference position. Subsequently, when the lap adjustment is necessary, by inputting the lap adjustment amount to the control device 550, the motor 547 rotates a predetermined amount while checking the signal from the potentiometer 549, and the grip cylinder 50 and the first The two holding cylinders 60 move to the position where the lap has been adjusted.

Note that the reference position in the perforated portion 20 is different from the reference position in the all-folded portion 10. The reference position in the all-folded portion 10 is ± 0 mm, whereas the reference position in the all-folded portion 10 is ± 0 mm. The reference position at 20 is a position of -5 mm.

That is, in accordance with the attachment / detachment operation of the brush guide 55, switching between the reference position in the perforated folding section 20 and the reference position in the all-folded section 10 and the reference position in the perforated folding section 20 and the all-folded section 10 are performed. Switching from the reference position to the lap adjustment position is linked.

As a result, the entire folding section 10 and the prop folding section 20
The relative phase between the gripper cylinder 50 and the second gripper cylinder 60 on the side that performs the folding process can be automatically switched in conjunction with the switching of the folding process between the steps (1) and (2). be able to.

Therefore, according to such a folding machine, the cutting of the cutting cylinder 30, the folding cylinder 40, the gripping cylinder 50, the second gripping cylinder (transfer cylinder) 60, and the like are performed in the propeller folding section 20 as compared with the full-length folding section 10. Since the cutting blade 31, the needle shafts 41 and 42, the knife shaft 44a, and the holding shaft 53 in the machine body are doubled and arranged, the diffracted light is diffracted twice in the all-folded portion 10 while the diffracted light is diffracted in the perforated portion 20. Can be performed, and the length of the signature of the entire signature section 10 and the signature of the perforated folding section 20 are the same, but the page of one signature is reduced to 1/4 of the signature of the entire signature section 10. can do.

As a result, the all-folded portion 10 and the prop-folded portion 20
Since different folding processes can be performed between and, switching of folding specifications can be performed extremely easily and in a short time,
The burden on the operator can be greatly reduced, and the preparation time can be significantly reduced, thereby improving the productivity.

Further, in the folding drum 40, all the folding portions 10
Two needle shafts 41 and four needle shafts 4 of the propeller folded portion 20
The needles 41a and 42a can be rotated by a single cam 423, and the knives 43a of the two knife shafts 43 of the entire folding part 10 and the four knife shafts 44 of the propeller folding part 20 can be rotated. Since the knife 44a can be rotated by the single cam 415, the number of parts can be reduced, the cost can be significantly reduced, and the size can be reduced. Further, since each cam is arranged on both sides of the body and reduced, the maintenance of the cam can be easily performed, and the burden on the operator can be greatly reduced.

In the folding cylinder 40, although the needle shaft 42 and the knife shaft 44 have substantially the same phase, the center side plate 41
0 to support the knife shaft 43, the lap amount can be adjusted during rotation, and the gripper cylinder 50 has a gripper shaft 53 and a second knife shaft 52.
Are substantially in phase with each other, but by arranging the center side plate 510 and supporting the second knife shaft 52, it is possible to adjust the lap amount during rotation. The burden can be greatly reduced.

When the folding process is performed at the entire folding section 10, by moving the first cam 522 from the retracted position to the operating position, it is possible to simultaneously move the second cam 523 from the operating position to the retracted position. When the folding process is performed by the propeller folding section 20, the first cam 522 can be moved from the operating position to the retracted position at the same time by moving the second cam 523 from the retracted position to the operating position. Wear of the grippers 51a, 53a, 54a and the like can be easily prevented.

Further, in conjunction with the switching of the folding process between the full-size folding section 10 and the prop folding section 20, the relative phase between the gripper cylinder 50 and the second gripper cylinder 60 on the folding side is automatically determined. The switching operation can be easily performed because the switching operation can be performed in an appropriate manner.

When the lap adjustment position is switched in all the folding sections 10, the brush guide 55 remains in contact with the grip cylinder 50 without operating.
