The present invention is constructed as described above, and its operation will be explained with reference to FIGS. 2 and 3(a), (b), and (c).

On both sides of the punch waste container 90, a light emitting element 100 and a light receiving element 101 are installed facing each other, and a signal from the light receiving element 101 is sent to the control section 85. Let us assume that the voltage level of 101 of this light receiving element is 3
If you explain it by dividing it into three parts (not limited to three),
When this level (110) is input to the control section 85, the control section 85 recognizes it. For example, if the analog value is divided into three levels and recognized, the voltage can be divided into three levels depending on the intensity of light entering the light receiving element 101, as shown in FIG. 3(a). When the punch waste container 90 is set at the specified position, the light emitted from the light emitting element 100 passes through a slit 90a provided in the punch waste container 90 and a translucent sheet 90b covering the slit 90a to the light receiving side. reach. Level 110 at this time is level 110-2
becomes. This is normal. Further, when the amount of light received is large, the level 110 changes to level 110-1, and when the amount of light received is small, the level 110 changes to level 110-3 (this change may be changed). Therefore, if there is no punch waste container 90, the amount of light will be maximum, which is level 110.
becomes level 110-1. Furthermore, if the punch waste container 90 is not set to the specified position but is at a halfway position, the slit 90a provided in the punch waste container 90 in FIG. It does not reach the light receiving element 101. Therefore, level 110 becomes level 110-3.

In addition, even if the punch waste container 90 is set in the specified position, if punch waste accumulates in the waste container 90, the slit 90
Since the debris blocks the light coming in through a, the light emitting element 10
The amount of light entering 1 is small. Therefore, level 110 is
The level becomes 110-3. Level 110 is level 11
0-1 or level 110-3, the display section 8 displays "Punch waste container 90 is not installed properly or is full of punch waste".
In addition to displaying 0, the punching action is disabled. The operation instruction display may also be inactive. And punch waste container 90
or reset the inactive function after setting the punch in place or discarding the punch waste.

Turn on the input switch 81 and insert the finger of the ring 6 into the upper claw 52.
When inserted into the sensor lever 60, the sensor lever 60 rotates counterclockwise around the shaft 60a, and the control unit 85 receives the size signal of the ring 6 and the inserted signal at the same time from the sensors 61a and 61b, and displays the display unit 8o. Sends a signal and displays sheet material set. At this time, the control unit 85 controls the size of the ring 6 according to the size of the ring 6.
Turn off the solenoid 13a or 13b and close the stopper 1.
2a or 12b protrudes into the through hole 10b of the die 10.
Next, the sheet material 2 is inserted until it abuts against the stopper 12a or 12b. Sensor 11 detected at the same time
The control unit 85 receives the signal from the controller 85 and sends the signal to the display unit 80 to display a punch display on the display unit 80. Next, when the perforation switch 84 is pressed and the upper limit sensor 37 or the sensor lever 97 is turned off due to disappearance (see FIG. 1(c)), the control section 85 that received the signal sends a signal to the solenoid 13a or the rising solenoid 13a. 13b is lowered to lower the stopper 12a (or 12b).

At the same time, the pusher 29 moves the lever 30, arm 16, cam 9
The sleeve 23 descends against the compression springs 27a and 27b, and the press plate 26 integrated with the push rod 25 presses the bundle of sheet materials 2. Then, the lowered presser plate 26 is attached to the claw 31a of the lock plate 31.
is locked. At the same time, the punch 17 descends and punches 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 pressed downward. The upper conveying roller 40b and lever 44 press 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, and sends a signal to the solenoid 4.
7 is turned on, and the lever 41 is locked via the rod 47a, the locking part 46a of the hook 46, and the protrusion 41c, and
Punch air rises. At this time, if the lower surface of the presser plate 26 presses the bundle of sheet materials 2 before the tip of the punch air, the bundle of sheet materials 2 can be pressed earlier than the beginning of punching with the die 10, and the sheet materials 2 can be pressed together. It is possible to prevent the disorder (misalignment) of the bundle. At this time, the sensor lever 97 or the lower limit sensor 3
Upon receiving the signal to turn off the ring 9, the control section 85 sends a signal to open the ring 6. On the other hand, when the sensor lever 90 turns on the upper limit sensor 37, the punch 17 has already been pulled out. Then, after the punch 17 has finished being pulled out from the sheet material 2, the arm 3 is lifted by the pusher 29.
5. The lock plate 31 rotates counterclockwise around the pin 32 via the release link 33, and the press plate 26 is released from the locked claw 31a, and the press plate 26 is separated from the bundle of sheet materials 2. . Then, the control unit 85 receives the signal to turn on the upper limit sensor 37, and sends a signal to the conveyor rollers 40a, 40b.
When the stepping motor 8 that drives the is turned on, the conveyance roller 40a is moved by a certain number of pulses.

40b to the link opening/closing section 7, the tip of the bundle of sheet materials 2 is prevented from being disturbed by the ring entrance guide 51 on the way, and after stopping at a suitable position relative to the opened link 6 shown in FIG. is closed. Note that the control unit 85 receives the signal to stop the stepping motor 8.
sends a signal to turn off the solenoid 47, and the protrusion 41c
is released from the locking portion 46a, and the upper conveyance roller 40b is lifted via the locking piece 41e of the lever 41 and the lever 44 by the urging force of the tension spring 41d. After the link 6 is closed, a stitching completion display is displayed on the display section 80, and the stitching operation is completed.

Next, after completing the work, the worker
Manually pull it out in the opposite direction to the direction in which it was transported. At this time, the human logite 49 and the link human logite 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.
It is guided by the guide plate 63 and descends. and drive plate 7
A component of force to the right in FIG. 13 is applied to the lower claw 56 through the oblique protrusion 67 or the oblique groove 66. Then, it is guided by the protrusion 65 of the lower claw 56 or the horizontal part of the dip 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 portions of the ring 6 downward. When the rack 71 is pushed upward by the motor 59, the lower claw 56 moves in the opposite manner to the above. 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
The upper conveying roller 40
b, without turning off the solenoid 47, and by reversing the motor 8 that drives the conveyance rollers 40a and 40b 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, a microswitch 770 on signal is issued, 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.

This mode is used when the punching capacity of the punch 17 etc. is insufficient for the stitching capacity of the ring 6, when additional punching is required after multiple punches, or when you want to perform replacement etc. This mode is used when automatic mode alone is inconvenient.

In the manual mode, since the sheet material 2 is not automatically conveyed, the ring 6 is opened and closed by operating the ring opening amount 82 and the ring closing amount 83 shown in FIG. 17. The opening amount is determined by the operator's judgment. The opening amount for the ring 6 is memorized by the control unit 85 as in the automatic mode, so the operator can obtain the opening amount for the ring 6 by pressing the ring opening amount 82 as many times as he deems optimal. Even if the ring opening amount 82 is pushed too far, will it still fit?
(It is designed so that the opening amount does not become larger than the one you learned in step 1). When the work is finished, the link closing 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, the detection means detects whether the punch waste container is full of punch waste or whether the punch waste container is not installed in a predetermined position. By detecting this, it is possible to easily determine the condition of the punch waste container inside the device, which is difficult to see visually, so it is possible to prevent failure of the device and prevent the area around and inside the device from being contaminated with punch waste. . Furthermore, since a plurality of states can be determined by one detection means, the reliability of the apparatus can be improved reliably and at low cost.

Further, if the punch chips are full or not set in the predetermined position, the control means automatically stops the operation of the punching means based on the detection signal, thereby preventing careless mistakes by the operator.
