Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting blade at a cutting portion of a stacked block folded below a folding device for folding a continuous paper of a form printing machine in a zigzag manner. The present invention relates to a checker device in a zigzag folding device configured to form a cutting blade body insertion gap in order to reliably insert a cutting blade body. 2. Description of the Related Art Conventionally, as shown in FIG. 6, a folded portion of a continuous paper a folded in a zigzag shape by a folding device is formed into a sashimi c on a discharge conveyor b which is arranged to be inclined downward. It is folded and discharged. In this case, the origami to be discharged is marked every predetermined number of sheets, and the marked portion is generally cut on a conveyor, and the paper is arranged and then packed in a box. [0003] In order for the origami to be sashimi-shaped and discharged onto the conveyor, the cutting work and the work of setting the folded shape both rely on humans and require labor.
Moreover, there is a problem in work efficiency. SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention has been made in consideration of the above-mentioned circumstances. Immediately below the fold, a vertically movable table is arranged, and the blade is positioned at the cutting part of the origami.In addition, a suction pipe provided with a suction port connected to a vacuum pump for enabling the blade to be inserted is vertically and vertically moved. It is provided so as to be movable horizontally, and the upper folded portion is held by the suction port for a certain period of time, so that the blade body insertion gap is configured with the lowering of the table. It is. The continuous paper P is folded on the elevating table 12,
At the time of the folding, when the blade body position provided at the end is reached, the suction tube 24 is moved by the signal to the position where the continuous paper is folded by the vertical cylinder 28 and the horizontal cylinder 31, and the suction port 24 a of the suction tube 24 by the vacuum pump 26.
Then, the folded portion of the continuous paper P is sucked and held for a certain period of time, and the continuous paper P is folded on the held upper portion for a short time. When a gap m that allows the blade body 23 to be inserted is formed between the blades 12, the blade body 23 is inserted at a predetermined position through the gap m, and when this insertion is completed, the table 12 is instantaneously moved to the position of the blade body 23. On the other hand, the suction pipe 24 is returned to the original state where the suction action is released by switching the switching valve 25. When a predetermined number of stacked blades reach a predetermined number, the knife 23a in the blade body 23 descends and cuts. When the cutting is completed, the blade body 23 retreats and returns to its original state and is folded. While the origami is discharged, the lifting table 12 rises and folds the origami. This operation is repeated. FIG. 1 shows an embodiment of a checker device provided in a zigzag folding device according to the present invention, which will be specifically described with reference to the drawings. As shown in the drawing, a frame 1 is provided with a pulling roll 4 via guide rolls 2 and 3 and a nip roll 5 for pressing the pulling roll 4 on the frame 1. The printed continuous paper P is pulled out by a guide roll 6 disposed in front of the pulling roll 4, and the pendulum arm 7 is driven by a pair of delivery rollers 8, 8 a provided at one end of a pendulum arm 7 pivotally supported at one end. The spiral bodies 10a to 10d and the beaters 11a to 1 of the lower folded portion A guided by the guide plate 9 provided in
The stacking table 12 is folded at a folding portion such as a perforation provided on the continuous paper P sent out at 1d, and is stacked on a vertically movable table 12 provided below, and the stacking table 12 descends according to the stacking height. The table 12 is connected to bearings 18, 1 via a motor 13, a coupling 14, a shaft 17, and a reduction gear 15a.
With the screw shaft 19 rotatably supported at 8a, the above-mentioned vertical movement is carried out via the nut 20 built in the table 12. An upwardly inclined suction port 24a is provided at the tip for holding the folded end portions close to the spiral bodies 10a to 10d respectively for a predetermined time to easily insert the cutting blade body 23. An L-shaped suction tube 24 is provided, and this suction tube 24 is connected to a vacuum pump 26 via an electromagnetic switching valve 25 by appropriate means to perform suction and release. The L-shaped suction tube 24 is provided in the spiral body 10
The support 2 slidably fitted on the guide rods 16 and 16a of a to 10d
A metal fitting 30 is arranged on a downward rod 29 of the tip of a vertical cylinder 28 mounted and supported by 7a to 27d, and is mounted via a metal fitting 33 mounted on a rod 32 of a horizontal cylinder 31 which is mounted horizontally with the vertical cylinder 28. Cylinder 31
Thus, the L-shaped suction tube 24 performs the operation in the L direction. That is, the spiral bodies 10a to 10d and the beaters 11a to
When the continuous paper P is folded from the folded portion at 11d, the suction tube 24 is pushed down by the vertical cylinder 28 and pushed out by the horizontal cylinder 31 to be located at the lower position of the folded portion, and the suction end of the suction tube 24 is suctioned by the vacuum pump 26. The folded portion is sucked at the opening 24a. Further, a blade 23 into which a knife 23a is inserted is located between the lower portion of the folding section and the table 12, and the blade 23 has a drive unit (not shown) for moving the blade 23 in the horizontal and vertical directions. This blade body 23 holds the above-mentioned folded portion by suction with a suction pipe 24 and at the same time as the table 12.
When the origami is gradually opened by the lowering of the blade to create a gap m, the blade body 23 moves in the horizontal direction and is inserted to a predetermined position. When the blade 23 is inserted, the electromagnetic switching valve 2
5, the suction is released and the suction pipe 24 is moved to the horizontal cylinder 31.
Then, the origami is continuously folded by the vertical cylinder 28 and the suction tube 24 is returned to the original position. As described above, according to the present invention, the suction tube provided with the suction port that moves horizontally up and down is connected to the vacuum pump so as to be positioned as the fold, and the fold is held at the upper portion for a certain period of time. By providing a gap for inserting the blade body located at the cutting part of the end of the folding part by sucking and lowering the lifting table, insertion and cutting can be reliably performed through the gap, and furthermore, the operation is automatically performed by a signal, so the blade The insertion position of the body is accurate and efficient.
