The paper is moved from a position where it comes into contact with the side surface of the sheet with a predetermined pressing force by a driving device 76 such as a rodless cylinder provided at a position retreating.

Next, the operation of each device having the above configuration will be described. (1) Origami paper separation position indicating device The rotating shaft 13 is rotated by the motor 28 and the screw rod 25 provided in the rail 11 is rotated forward to thereby rotate the rail 11.
The feed pieces 31 and 32 move to the upstream side along. Thereby, the sliding piece 33 engaged with the rail 11 is pushed by the downstream sending piece 32 and moves to the upstream side. When the sliding piece 33 reaches a predetermined position on the upstream side,
This is detected by the position detection sensor 45 on the upstream side, the motor 28 is rotated in the reverse direction, the screw rod 25 is slightly rotated in the reverse direction, and
1,32 feed to L ₂ only downstream of the upstream feed piece 3
1 is brought into contact with the upstream side of the sliding piece 33. Thus, the sliding piece 33 enters a standby state. At this time, the separation spatula 36 moves to the upstream side together with the sliding piece 33, and the pins 39a and 39b of the rotating lever 35 are moved to the guide cam 4 at the end.
0, and the separation spatula 36 abuts on the guide rod 38, thereby controlling the attitude of the separation spatula 36 so as to be parallel to the rail 11 (FIG. 3).

On the other hand, along with the movement of the sliding piece 33, the lifting device 17 is operated to raise the upstream side of the rail 11, and the rail 11 is inclined from the upstream side of the folding machine 1 to the cutting device 9 (FIG. 1). ). After that, the cylinder devices 24a and 24b for offset are extended to push the rail 11 toward the folding machine 1, and the separating spatula 36 is positioned on the upstream side of the folded paper 3 and in the feeding direction as shown by a virtual line in FIG. To a position where it interferes with With the above operation, the separation position indicating device enters a standby state. When the number of folded sheets of the folded paper 3 discharged from the folding machine 1 reaches a set value by a fold number detection sensor (not shown), the pushing cylinder device 44 is operated to move the sliding piece 33 to both sides. Feeding pieces 31, 3
Just enough to take up the play in L ₂ between 2 pushed out to the downstream side.

As a result, the separating spatula 36 is inserted upstream of the folded sheet 3 discharged from the folding machine 1. At the same time, the feed motor 28 is driven in the reverse direction to
Is rotated in the reverse direction, and the feed frames 31 and 32 are moved downstream at substantially the same speed as the transport speed of the receiving belt 6 and the transport belts 7a and 7b. Thereby the sliding piece 33 after the feed frame 31 of the upstream side is moved by L _2, it is moved along the rail 11 to the downstream side together with the upstream folding sheet 3 by being pushed by the feed frame 31 of the upstream side. At this time, since the folded paper 3 is sequentially conveyed obliquely downward from the receiving belt 6 to the conveying belts 7a and 7b toward the downstream side, the lifting device 17 gradually lowers the upstream side of the rail 11. As a result, the separating spatula 36 is in a free state with the guide bar 38 and the guide cam 40 separated from each other, so that the separating spatula 36 is held between the folded sheets 3 and the fixed At this position, it moves together with the folded sheet 3 along the mountain side perforation.

When the sliding piece 33 is at the predetermined position on the downstream side, the position detecting sensor 46 is operated and the screw rod 25 is stopped. At this time, at a position where the sliding piece 33 approaches the downstream end position, the rotating lever 35 is moved to the two guide cams 41a, 4a.
1b, and is raised, and then the locking projection 36b
Is engaged with the positioning member 42, so that the separation spatula 3
6 is stopped and fixed in a state of being directed obliquely upward on the downstream side as shown in FIG. By the above operation, the separation position at the cutting position of the folded sheet 3 is indicated by the separation spatula 36. In this state, the cutter 63 of the cutting device 9 is inserted from the cutter guide portion 36a of the separation spatula 36, and is moved in the width direction.
Is disconnected. After cutting the folded sheet 3, the offset cylinder devices 24a and 24b are shortened to move the rail 11 outward in the width direction, and then the screw rod 25 is rotated forward. Thus, the sliding piece 33 is returned to the upstream side by the downstream sending piece 32. At this time, the separation spatula 36 is folded paper 3
Does not interfere with

(2) Cutting device During the operation of the separating position indicating device 8, the moving frame 51 is moved upstream to the stroke end set by the sensor 51a, and the frame 55 for the cutting device is moved.
Is located on the downstream side, and the moving body 59 is further moved to the near side in the width direction of the paper 3. In this state, the cutting device 9
The cutter 63 is opposed to the outside in the width direction of the cutter guide portion 36a of the separation spatula 36 stopped at the downstream side of the separation position indicating device 8. By operating the rodless cylinder 58 in this state to move the moving body 59, the cutter 63 is first guided by the cutter guide portion 36a of the separation spatula 36 and inserted into the fold of the sheet 3, and the fold is left as it is. Along with the cutter 63. At this time,
By gradually raising the cutter 63 by the cylinder device 62 in conjunction with the movement of the moving body 59, the cutter 63 becomes sharper and is cut cleanly.

After the cutting, the cutter 63 is returned to the center of the folded sheet 3, and the entire cutting device 9 is moved to the upstream side by the cylinder device 64. As a result, as shown in FIG. 10, the folded sheet 3 on the upstream side of the cutting section is pushed on the sheet pressing surface, which is the upstream end face of the cutter table 61, and the cut section is separated in the flow direction. A gap 80 is provided on the downstream side of.
At the time of the above operation, the flow height of the folded paper 3 changes due to a change in the type of the paper 3 and the folding speed, and the flow height of the folded paper 3 at this time is detected by the paper height detection sensor 65. The worm gear mechanism 68 is automatically driven by the command from the sensor 65, and the guide frame 50 is moved up and down, so that the positional relationship between the flow height of the paper 3 and the cutter 63 and the separation spatula 36 is always constant. Is done.

(3) Sorting Device In the above operation, the support 70 of the sorting device 10 is moved to the upstream side in the feeding direction of the folded paper 3 so that the side press plates 75a and 75b are slightly shifted from the cutting position by the cutting device 9. It is made to face the side of the folded paper 3 on the downstream side. Then, the side press plates 75a and 75b of the sorting device 10 are operated in the facing direction in a state where the cutting device 9 has a gap 80 in the flow direction at the cutting position of the folded paper 3.
As a result, as shown in FIG. 12, both sides of the folded sheet 3 downstream of the cutting position 9 are clamped by a predetermined pressing force, and the folded sheet 3 downstream of this portion is located upstream of the cutting device 9. Sorting is performed on the folded paper 3.

Since the downstream folded paper 3 sorted by the sorting apparatus 10 is on the second conveyor belt 7b,
In this state, the sorting device 10 is moved to the downstream side at the same speed and at a high speed with the second transport belt 7b, so that the folded sheets 3 on the downstream side from the cutting position by the cutting device 9 are gathered together. It is discharged by the second conveyor belt 7b. Then, at this unloading entanglement position, the side press plate 75a,
75b is retracted, and then the sorting device 10 is returned to the upstream side. In the above-described embodiment, the example in which the cutting device 9 is supported by the moving frame 51 so as to be movable in the paper feeding direction has been described. However, this is because the cutting device 9 is largely changed in the feeding direction of the folded paper 3. If necessary, the moving frame 51 may be integrated with the guide frame 50 if not necessary.
