is locked by the claw 31a of the lock plate 31. At the same time, the bunch 17 descends and perforates the bundle of sheet materials 2 on the die 10, and at the same time, the pickup arm 42 is pushed downward against the upward biasing force, and the pickup lever 41 is The upper conveying roller 40b and the lever 44 push the bundle of sheet materials 2 downward by their own weight, and the control unit 85 receives a signal from the lower limit sensor 39 which is turned on at the same time, sends a signal, and the solenoid 47 is turned on. Then, the lever 41 is locked via the core frame 47a, the locking part 46a of the hook 46, and the protrusion 41c, and the bunch 17 is raised. At this time, if the lower surface of the presser plate 26 presses the bundle of sheet materials 2 before the tip of the bunch 17, the bundle of sheet materials 2 can be pressed down earlier than the die 10 starts perforating the sheet material. Disturbance (misalignment) of the bundles in step 2 can be prevented. At this time, the control unit 85 receives a signal from the sensor lever 96 to turn off the lower limit sensor 39, and sends a signal to open the ring 6. On the other hand, when the sensor lever 90 turns on the upper limit sensor 37,
Bunch 17 has already been pulled out. And punch 1

The presser plate 26 is released from the locked claw 31a, and the presser plate 26 is separated from the bundle of sheet materials 2. Then, the control unit 85 that receives the signal that turns on the upper limit sensor 37 sends a signal.
When the stepping motor 8 that drives the conveyance rollers 40a, 40b is turned on, the sheet material 2 is conveyed to the ring opening/closing section 7 by the conveyance rollers 40a, 40b by a certain number of pulses, and the tip of the bundle of sheet materials 2 is moved by the ring entrance guide 51 along the way. After the ring 6 has been prevented from being disturbed and has stopped in a suitable position relative to the open link 6 shown in FIG. 12, the ring 6 is closed. In addition, upon receiving the signal to stop the stepping motor 8, the control section 85 sends a signal to turn off the solenoid 47, and the protrusion 41c is disengaged from the locking section 46a, and the upper conveyance roller 40b is removed.

The binding work is completed.

Next, after completing the work, the worker
is manually pulled out in the opposite direction to the conveyance direction. At this time, the entrance guide 49 and the ring entrance guide 51 rotate clockwise and do not resist (see FIG. 9(b)).

Next, the operation of the lower claw 56 will be explained with reference to FIGS. 13 and 14. When the rack 71 is lowered by the motor 59 via the gear train 57 shown in FIG.
is guided by the guide plate 63 and descends. and drive plate 7
The oblique protrusion 67 of 0 applies a rightward component force in FIG. 13 to the lower claw 56 via the oblique groove 66. Then, the protrusion 65 of the lower claw 56 is guided by the horizontal part of the groove 62 of the guide plate 63, moves to the right, becomes capable of engaging with the finger of the ring 6, and is then moved by the downward force. Guided by the vertical portion of the groove 62, the lower claw 56 descends and opens the finger portion of the ring 6 downward. When the rack 71 is pushed upward by the motor 59, the lower claw 56 moves in the opposite direction. Note that the holding plate 72 is attached to the screw 75.
It is integrated with the driving plate 70 via the lower claw 56 and always holds the lower claw 56 therebetween. For this reason, since the screw 75 moves in the same manner as the oblique protrusion 67, an oblique hole 73 similar to the oblique groove 66 is provided in the lower claw 56.

In addition, in the above embodiment, the sheet material 2 that has been stitched

b, without turning off the solenoid 47, and by reversing the motor 8 that drives the conveyance rollers 40a and 4ob when the stitching completion display is displayed on the display unit 80, the stitched sheet material 2 may be automatically drawn out.

By doing so, it is possible to improve the labor and time saving of the stitching work.

Next, the operation of the manual mode will be explained. As shown in FIG. 15, when the main body 7a is tilted around the bin 76 and fixed, an on signal is generated from the microswitch 77, and upon receiving this signal, the control section 85 switches the control system to manual mode.

Then, the auxiliary guide 79 rotates clockwise around the bin 79a to support and guide the sheet material 2 in the manual mode.

In this mode, if the perforation capacity of the punch 17 or the like is insufficient for the stitching capacity of the rings 6, it is necessary to perform additional perforation multiple times. This mode is also used when there are cases where it is desired to perform replacement, etc., and automatic mode alone is inconvenient.

In the manual mode, the sheet material 2 is not automatically conveyed, so the rings 6 are opened and closed by operating the inter-ring 0 button 82 and the ring close button 83 shown in FIG. 17. rfI4
The determination of zero amount is made by the judgment of the operator. The opening amount for the ring 6 is controlled by the control unit 8 in the same way as in the automatic mode.
5, the operator should remember the ring opening amount 82.
The opening amount of the ring 6 can be obtained by pressing the ring 6 as many times as you think is optimal (even if the ring opening amount 82 is pushed too much, it will not become larger than the opening amount memorized in the device 1). When the work is finished, the ring closure 83 is pressed to perform a closing operation and the work is completed.

If you want to add or replace sheet material 2, please refer to Fig. 16(a).
When the sheet material 2 is set under the upper claw 52 and the ring opening amount 82 is adjusted as shown in FIG. You can freely replace it.

By tilting the main body 7a, visibility can be improved and usability can be further expanded.

(G) As described in detail, according to the present invention, when the punch waste container (90) is full of punch waste, the stopper (12a, 1
Since the detecting means (93) detects when the punch 2b) performs the sinking operation, it is easily determined that the punch waste container (90), which is difficult to see visually, is full, so punch waste in the punch waste container (90) is removed. As a result, functional failures of the device (1) can be eliminated, failures of the device can be prevented, and the area around the device (1) can be prevented from being contaminated with punch waste.
