is arranged at the middle of the paper 3 in the width direction. 76 comb 7
It is a guide rod for vertical movement of 4.

Next, the operation of each device having the above configuration will be explained.

(1) Folded paper separation position indicating device The rotating shaft 13 is rotated by the motor 28, and the threaded rod 25 provided inside the rail 11 is rotated in the normal direction.
The feed frames 31 and 32 move to the upstream side along. As a result, the sliding piece 33 engaged with the rail 11 is pushed by the feeding piece 32 on the downstream side and moves upstream. When this sliding piece 33 reaches a predetermined position on the upstream side,
This is detected by the upstream position detection sensor 45, the motor 28 is reversed, the screw rod 25 is slightly reversed, and the feed frame 31 is rotated.
．． 32 to the downstream side by a distance p, and the upstream feeding piece 31 is brought into contact with the upstream side of the sliding piece 33. Now sliding piece 3
3 is in a standby state.

At this time, the separating spatula 36 also moves upstream together with the sliding piece 33, and at its terminal end, the pins 39a and 39b of the rotating lever 35 come into contact with the guide cam 4°.
When the separating spatula 36 comes into contact with the guide rod 38, the attitude of the separating spatula 36 is controlled so that it is parallel to the rail 11.

On the other hand, as the sliding piece 33 moves, the lifting device 17 is operated to raise the upstream side of the rail 11.
is inclined across the cutting device 9 from the upstream side of the folding machine 1.

After that, the cylinder device 24a for offset.

24b is extended to push the rail 11 toward the folding machine 1, and the separating spatula 36 is moved to a position upstream of the folded paper 3 and interfering with the feeding direction, as shown by the imaginary line in FIG.

The above operation puts the separation position pointing device into a standby state.

When a fold number detection sensor (not shown) detects that the number of folds of the paper 3 discharged from the folding machine 1 has reached a set value, the pushing cylinder device 44 is activated to feed the sliding piece 33 in both directions. It is pushed downstream by the amount of play g between the pieces 31 and 32.

As a result, the separation spatula 36 is inserted into the upstream side of the folded paper 3 discharged from the folding machine 1. At the same time, the feed motor 28 is driven in the reverse direction, the threaded rod 25 is reversed, and the feed pieces 31 and 32 are moved downstream, with the belt 6 being the receiver and the conveyor bell 7a.

It is moved at approximately the same speed as the conveyance speed by 7b.

As a result, after the upstream feeding piece 31 has moved by g, the sliding piece 33 is pushed by the upstream feeding piece 31 and is moved downstream along the rail 11 together with the upstream folded sheet 3.

At this time, the folded paper 3 is placed on the conveyor belt 7 rather than on the belt 6.
Since the rails 11 are sequentially conveyed obliquely downward toward the downstream side, the upstream side of the rail 11 is gradually lowered by the lifting device 17. As a result, the separating spatula 36 is in a free state, having left the guide rod 38 and the guide cam 4°, so that the separating spatula 36 is in a state of being sandwiched between the folded sheets 3, and is in a free state. It moves together with the paper 3 along the mountain side perforation at a fixed position.

When the sliding piece 33 is at a predetermined position on the downstream side, the position detection sensor 46 is activated and the screw rod 25 is stopped.

At this time, the rotating lever 35 is guided by the two guide cams 41a and 41b and raised at a position where the sliding piece 33 approaches the downstream end position, and then the locking protrusion 36b engages with the positioning member 42. As a result, the separation spatula 36 is stopped and fixed in a state facing obliquely upward on the downstream side, as shown in FIG.

By the above action, the separation position at the cutting position of the paper 3 is indicated by the separation spatula 36.

In this state, the cutter 63 of the cutting device 9 is inserted through the cutter guide portion 36a of the separation spatula 36 and moved in the width direction, thereby cutting the paper 3 at the position where the separation spatula 36 is inserted.

After cutting the paper 3, an offset cylinder device 24a,
24b is shortened to move the rail 11 to the outside in the width direction, and then the screw rod 25 is rotated in the normal direction. As a result, the sliding piece 33 is returned to the upstream side by the feeding piece 32 on the downstream side.

At this time, the separation spatula 36 does not interfere with the paper 3.

(2) Cutting device While the separation position indicating device 8 is in operation, the movable frame 51 is moved upstream to the stroke end set by the sensor 51a, and the frame 55 for the cutting device is positioned downstream, Further, the moving body 59 is moved toward the front side in the width direction of the paper 3.

In this state, the cutter 63 of the cutting device 9 faces the outside in the width direction of the cutter guide portion 36a of the separation spatula 36 that is stopped on the downstream side of the separation position indicating device 8.

In this state, the rodless cylinder 58 is operated to
9, the cutter 63 is first guided by the cutter guide part 36a of the separation spatula 36 and inserted into the fold edge of the paper 3, and then the cutter 63 is inserted along this fold line.
It will be cut at.

At this time, in conjunction with the movement of the movable body 59, the cylinder device 6
By gradually raising the cutter 63 at step 2, the cutter 6
3. The sharpness becomes better and cuts are made more cleanly.

After cutting, the cutter 63 is returned to the center of the paper 3, and the entire cutting device 9 is moved upstream using the cylinder device 64. In this way, as shown in FIG. 10, the folded paper 3 on the upstream side of the cutting section is pressed by the paper pressing surface which is the upstream end surface of the cutter table 61, the cutting section is separated in the flow direction, and the folded sheet 3 on the upstream side of the cutter table 61 is pressed.
A gap 80 is provided on the downstream side of 1.

During the above operation, the flow height of the paper 3 changes depending on the type of paper 3, changes in the folding speed, etc., but the flow height of the paper 3 at this time is detected by the paper height detection sensor 65, and the paper height detection sensor 65 detects the flow height of the paper 3 at this time. 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 to adjust the flow height of the paper 3, the cutter 63, and the separation spatula 36.
are controlled so that the positional relationship between them is always constant.

(3) Separation is carried out by the above-mentioned cutting device 9 with a gap 80 opened in the paper flow direction at the cutting position of the paper 3. The comb 74 is separated by extending the comb insertion cylinder device 73 of the device 10. Gap 80
Insert into. Thereafter, the cylinder device 71 for pushing and opening is moved to extend and the comb 74 is pushed back to the upstream side.

As a result, as shown in FIG. 11, the paper 3 on the upper and downstream sides of the cutting position is largely divided into upper and downstream directions at this position.

The paper 3 on the downstream side separated by the device 10 is on the second conveyor belt 7b, so in this state, the upstream side of the second conveyor belt 7b is moved upward and tilted toward the downstream side. , this section conveys only the latter sheet 3 to the downstream side.

At this time, the second conveyor belt 7b is fast-forwarded.

Further, even during the sorting operation of the apparatus 10, the sheets 3 are continuously discharged from the folding machine 1, so the movable frame 51 is moved downstream in synchronization with the speed at which the sheets 3 are discharged.

For sorting, after the paper 3 on the downstream side has been conveyed downstream, the second conveyor belt 7b is returned to the horizontal position, and then the comb 74 of the device 10 is moved upward to separate it from the paper 3. At the same time, it is pulled back downstream. Similarly, the cutting device 9 is also returned to its original position. Then, the moving frame 51 is further returned to the upstream side.
