DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. In the description, the same members as those of the conventional example are designated by the same reference numerals, and the description thereof will be omitted. Only the members newly added in the present invention will be denoted by new numbers and described.

A running paper 33 is run between the horizontal sewing machine blade cylinder 1 having the horizontal sewing machine blade 36 installed in the width direction and the horizontal sewing machine receiving cylinder 2 having the horizontal sewing machine receiver 39 installed in the width direction so that the two cylinders 1 and 2 are synchronized with each other. However, each time the drums 1 and 2 rotate once, the running paper 3
3 is provided with perforations 40 at a constant interval, which is completely the same as that of the conventional device described above, and is different from the conventional device in that a clutch is provided in a drive device that drives the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving cylinder 2. It is provided that the power from the drive source is transmitted or not transmitted to the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving cylinder 2 by turning on and off.

The drive system will be described with reference to FIG. 1. The power from the drive source of the folder, not shown, is the intermediate shaft 20.
Is transmitted to the first gear 21 rotatably attached to
Then, the second gear wheel 22, which is mounted in a non-rotatable state on the shaft 20 by the spline 50 so as to be movable in the axial direction by a predetermined distance in series with the coaxial shaft 20, is rotated via the clutch 12.

In the clutch 12, an air silling 14 which is operated by a perforation opening / closing command signal moves a shaft 26 parallel to the intermediate shaft 20 forward and backward, and a shifter 13 fixed at a right angle to the coaxial shaft 26 is the second shifter 13. When the first gear 21 and the second gear 22 are connected to each other, the running paper 33 is previously transferred to the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving cylinder 2 when the gear 22 is moved in and out in the axial direction. Since the perforations are not adjusted so that the perforations are placed at the proper positions on the printing surface in the step before entering, the shifter 13 is moved to the right in the figure from the illustrated position, and the side surface 48 of the second gear 22 is moved through the bearing 47. Press,
By moving the gear 22 to the right, the clutch 12
At the same time, the perforations 40 are put in the running paper 33.

When the clutch 12 is not disengaged, the intermediate shaft 20 rotates so that the rotation of the intermediate shaft 20 is provided at the end of the shaft.
It is stopped by 9, and when the clutch 12 is engaged,
That is, when the air cylinder 14 reaches the stroke end, the brake device 49 is disengaged by a signal from a signal transmitter such as a limit switch (not shown), and the intermediate shaft 20
It is possible to rotate.

Therefore, the intermediate shaft 20 becomes rotatable after the clutch 12 is engaged, and the gear 22 is rotated by the gear 21 via the spline 50.

The second gear 22 is a horizontal sewing machine blade cylinder 1.
Is engaged with a gear 41 attached to the horizontal sewing machine barrel 2 having the same number of blades as the gear 41. That is, the second gear 2
When 2 rotates, gear 41 and gear 42 rotate in synchronization with each other.

A lateral sewing machine blade position detection device (hereinafter referred to as a detection device) 23 is attached to the shaft end of the horizontal sewing machine blade cylinder 1. The detection device 23 is attached to a bracket 25 fixed to the shaft end surface of the horizontal sewing machine blade cylinder 1 so as to have the same axis as the axis of the horizontal sewing machine cylinder 1, and the detection piece 2 is attached at a right angle to the axis.
7 and a proximity switch 28 for detecting the detection piece 27, and the outside thereof is covered with a safety cover 29.

The detection piece 27 has a long and narrow plate-like shape, and the slit portion 46 provided in the proximity switch 28 has the same phase as the horizontal sewing machine blade 36 provided in the horizontal sewing machine body 1 in the rotating direction of the body 1. A signal is transmitted from the proximity switch 28 when the plate width at the tip of the detection piece 27 attached in step 4 passes. That is, when the horizontal sewing machine blade 36 and the horizontal sewing machine bridge 37 are engaged, if the signal is transmitted only when a predetermined width before and after the engagement, the horizontal sewing machine blade 36 and the horizontal sewing machine blade 37 are engaged when no signal is generated. The receiver 37 is not engaged, and the running paper 33
Will not be perforated.

The detection device 23 may be attached not only to the horizontal sewing machine blade cylinder 1 but also to the horizontal sewing machine receiving cylinder 2. As described above, the mounting position of the detection plate 27 is not only to detect the engaging position of the horizontal sewing machine blade 36 and the horizontal sewing machine bridge 37, but also the opposite side of the horizontal sewing machine blade 36 and the horizontal sewing machine bridge 37. You may detect the position which does not match. Therefore, in that case, in the case of horizontal perforation cutting, the detection device 23 detects the position of the horizontal perforation blade 36 or the horizontal perforation receiver 37 in which the perforation does not enter. Therefore, for example, as shown in FIG. The sewing machine blade 36 and the horizontal sewing machine bridge 37 are rotated by 180 ° from the position where they are in contact with each other and are in a position where they do not engage with each other. While the signal from the detection device 23 is not transmitted, the clutch 12
When turned off, both cylinders 1 and 2 will not rotate and will stop at a position where perforations do not enter.

When the air cylinder 14 retreats to the stroke end in response to the perforation command signal, the brake device 49 operates, the rotation of the intermediate shaft 20 is stopped again, the gear 22 is separated from the gear 21, and the drive source is disconnected. Is stopped, and the gears 41 and 42 of the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving body 2 meshing with the gear 22 stop at a position where the horizontal sewing machine blade 36 and the horizontal sewing machine receiving 37 do not engage and remain as they are. Position is retained.

Next, referring to the flowchart of FIG.

First, the case of perforation will be described. In step (1ST), the brake device 49 is engaged, that is, the intermediate shaft 20 is disabled and the clutch 12 is disengaged. Next, at 2ST, the perforation signal is turned on by a push button or the like. In 3ST, an alarm such as a buzzer will be issued to the surrounding area to prepare for perforation to prevent danger. In 4ST, in order to make an appropriate perforation on the printing surface of the running paper 33, the main motor of the drive source is rotated so as to rotate the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving cylinder 2 at an inching speed.

At 5ST, the operation of the air cylinder 14, that is,
The operation of the shifter 13 is performed. Clutch 12 at 6ST
It is judged whether or not the splicing state has ended, and if YES, 7ST
The brake device 49 is turned off so that the intermediate shaft 20 to which the gear 22 is attached can be rotated. If NO, YES, that is,
It will wait until the intermediate shaft 20 becomes rotatable.
When the above adjustment process is completed, the entire apparatus is temporarily stopped at 8ST in preparation for operation start (perforation is made), and perforation operation is started at 9ST.

Next, the case of perforation cutting will be described. At 1ST, the brake device 49 is disengaged, that is, the intermediate shaft 20 is rotatable and the clutch 12 is engaged. Next, in 2ST, the signal for cutting the sewing machine is turned on by a push button or the like.

In 3ST, an alarm such as a buzzer is issued to the surroundings so as to prepare for the perforation of the sewing machine to prevent danger.
In 4ST, in order to make adjustments so that no perforations are made on the printing surface of the running paper 33, the motor of the drive source is rotated so as to rotate the horizontal sewing machine blade cylinder 1 and the horizontal sewing machine receiving cylinder 2 at an inching speed. In 5ST, it is determined whether or not there is a signal from the detection device 23 that detects the proper position where the horizontal sewing machine tool barrel 1 does not engage with the horizontal sewing machine receiving cylinder 2, and if YES, the operation of the 6ST air cylinder 14, that is, The operation of the shifter 13 is performed.
In the case of NO, the process waits until the state is YES, that is, the lateral sewing machine blade 36 is in the proper state in which it does not engage with the lateral sewing machine bridge 37.

When the above adjustment process is completed, the clutch 12 is disengaged at 7ST, and at the same time the brake device 49 is inserted, and at the same time 8ST, the entire device is temporarily stopped in preparation for starting operation (without perforation). , 9ST
Then the operation started without perforation.
