Description of operation Based on the above-described embodiment, the division cutting device A
The operation of will be described. When the top and bottom and the edge are cut by the three-side cutting machine 4 and the bookbinding is a single face, the frame body 16 having the upper blade 18 is at the highest position and the stopper member 28 as shown in FIGS. The frame body 26 having is at the lowest position, and the motor 44 rotates in response to the operation signal of the sensor 23 to rotate the drive shaft 42. At this time, the one-way clutch 45 makes the sprocket 46 free with respect to the drive shaft 42. That is, the rotation of the drive transmission shaft 7 is not driven by the disengagement of the fixed point mesh clutch 8 and the operation of the non-excitation brake 9. The rotation of the drive shaft 42 due to the rotational driving of the motor 44 is performed by the sprocket 57 and the chain 58.
1 is continuously rotated to drive the transport bodies 32 and 36 in the direction of the arrow in FIG. 2, and the bookbinding passes through the frame body 16 and is fed to the stacker 6 via the transport body 36 for post-processing.

When the circuit of the sensor 23 is turned off, the motor 44 is stopped, the fixed point meshing clutch 8 is engaged, the non-excitation brake 9 is released, and the rotational drive of the drive transmission shaft 7 is transmitted to the drive transmission shaft 7a. This rotation is driven by the drive gear 11
It is transmitted to the gear 13 via the gear 13, and the rotation of the gear 13 moves the frame 16 up and down by the action of the pin 14 of the crankboard 15. At the same time, by rotating the cam 25 provided on the crankshaft 12, the frame body 26 is moved up and down via the engagement pin 27,
Multi-sided bookbinding stopper member 28 conveyed by the conveyor 32
Place the back side of the multi-sided book on to prevent the progress and position it. At the same time, the frame body 16 is lowered to cut the multi-sided booklet while it is stopped. When the division cutting is completed, the upper blade 18 of the frame body 16 is raised to the highest position by the crankshaft 12 which is continuously rotating, and on the contrary, the stopper member 26 of the frame body 26 is lowered to the ascending and descending position. Be prepared to accept multi-sided book binding. The vertical movements of the frames 16 and 21 and the supply of multi-sided bookbinding are configured such that the operations of the three-sided cutting machine 4 are interlocked with each other so that the timings match. In connection with this division cutting operation, the conveying bodies 32 and 36 are given an intermittent conveying operation with a constant stroke. Next, its operation will be described. The gear 24 coaxial with the gear 13 is
It is rotating continuously. By the action of the groove 50 provided on one side surface of the gear 24 and the rolling wheel 53 of the sprocket 52, the sprocket 52 is given an intermittent rotation action. This intermittent rotation action is transmitted to the sprocket 46 having the one-way clutch 45 via the chain 54, and imparts the same intermittent rotation motion to the drive shaft 42 that is in an insulated state from the motor 44. The intermittent rotation of the drive shaft 42 is caused by the sprocket 5
7, sprocket 40 of carrier 32 via chain 58
And actuating the sprocket 41 of the carrier 36,
2 and 36 are given an intermittent feeding action shown in the direction of the arrow in FIG.
The feeding of the multi-sided bookbinding is stopped during the division by the lower blades 18 and 18a.

[0014]

As described above, according to the structure of the present invention, the following effects can be obtained. (A) In the case where the booklet whose top and bottom are cut by a three-sided cutting machine has a single surface, the sensor and a fixed point meshing clutch electrically connected to the sensor and a non-excitation brake are operated to operate the split cutting means. The upper blade constituting the upper limit can be retracted to the upper limit, the stopper member can be retracted to the lower limit, and the belt conveyor can be continuously operated by the motor of the rotating shaft to pass the bookbinding. (B) In the case where binding is performed on the top and bottom by a three-side cutting machine and the binding is multifaceted, the motor of the switching rotary shaft is stopped by the signal of the sensor, and the belt conveyor is divided by driving the intermittent rotation motion means. It is possible to apply the intermittent motion of the cutting means at a timed timing, and to divide the multi-sided booklet appropriately and to cut it, and the switching can be performed by one-touch operation.
