In addition, as shown in FIG. 15(b), when the main body 7a is tilted and fixed, the auxiliary guide 79 is rotated counterclockwise around the bin 79a by an elastic member (not shown), and in the manual mode. It forms a guide surface for the sheet material 2. Furthermore, as shown in FIG.
installed on.

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

First, select AUTO in FIG. 2(a) and press the input switch 81.
When the ring 6 is turned on and the finger of the ring 6 is inserted into the upper claw 52, the sensor lever 60 rotates counterclockwise around the shaft 60a, and the sensor 61a transmits the size signal of the ring 6 and the signal inserted at the same time. , 61b, the control unit 85 receives the display unit 80 from the display unit 80.
Sends a signal to display the sheet material set. At this time, the control section 85 controls the solenoid 13a according to the size of the song 6.
Or turn off stopper 13b and stopper 12a or 12b.
0 protrudes into the through hole 10b of the die 10. Next, the sheet material 2 is inserted until it comes into contact with the stopper 12a or 12b. At the same time, the control unit 85 receives a signal from the sensor 11 that is detected, and sends a signal to the display unit 80 to display a punch display on the display unit 8o.Next, when the perforation switch 84 is pressed,
When the upper limit sensor 37 is turned off due to the disappearance of the sensor lever 97, the control section 85 that receives the signal sends a signal to lower the ascending solenoid 13a or 13b, thereby lowering the stopper 12a (or 12b).

At this time, the punch waste box 90 is filled with punch waste,
Furthermore, if the punch waste box 90 is raised higher than the upper surface, the downwardly directed protrusions 91b of the stoppers 12a, 12b will not descend to a predetermined position.

That is, if the stopper detection switch 92 is not turned on even after a short period of time after the upper limit sensor 37 is turned off, the dust detection means 93 is turned on. On the other hand, the perforation motor 90 may rotate the cam 93 once to complete the perforation work on the sheet material 2, but the upper limit sensor 37 must not be turned on again and the conveyance motor 8 must be started. (This is because the stopper 12a or 12b interferes with the sheet material 2.) Therefore, when the dust detection means 93 is turned on, a "full dust" message is displayed on the display section 80, and at least the upper and lower limit sensors 37,
39 is made inactive. The operation instruction display may also be inactive. Then, after taking out the punch waste box 90 and discarding the punch waste, the upper and lower limit sensors 37 and 3 are installed inside the device 1.
9 and the operation instruction display functions are reset, and the operation is resumed from the punch display shown in the flowchart shown in FIG.

When the punch waste box is normal, the stopper 12a
(or 12b), the push platform 29 is pushed down by the motor 90 via the lever 15, the arm 16, the cam 93, etc., and the sleeve 23 is moved by the compression spring 27a,
27b, the presser plate 26 integrated with the presser rod 25 presses the bundle of sheet materials 2. Then, the presser plate 26 descended.
is locked by the claw 31a of the lock plate 31. At the same time, the bunch air descends and perforates the bundle of sheet materials 2 on the guide rod, and at the same time, the pickup arm 42 is pushed downward against the upward biasing force, and the pickup lever 41 descends. And if the upper conveyance roller 40b is i<-44
presses the bundle of sheet materials 2 downward with its own weight, and at the same time, the control unit 85 receives a signal from the lower limit sensor 39 which is turned on.
sends a signal, solenoid 47 turns on, and
The locking portion 46a of the hook 46 and the protrusion 41. The lever 41 is locked through the lever c, and the punches 1 and 7 are 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 east side of the sheet material 2 can be pressed down before the die 1o starts perforating the sheet material. Disturbance (misalignment) of the bundles in step 2 can be prevented. At this time,
Upon receiving the signal from the sensor lever 98 to turn off the lower limit sensor 39, 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 bunch air has already been drawn out. Then, when the bunch air is completely pulled out from the sheet material 2, as the pusher 29 rises, the lock plate 31 rotates counterclockwise around the pin 32 via the arm 35 and the release link 33. 26 is released from the locked claw 31a,
The presser plate 26 is separated from the bundle of sheet materials 2. When the control section 85 receives the signal that turns on the upper limit sensor 37, it sends a signal and turns on the stepping motor 8 that drives the conveyance rollers 40a, 40b. 7, the leading end 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 open link 6 shown in FIG. 12, the ring 6 closes.

Then, the ring 6 opens and a stitching completion indication appears on the display section 8.
0, the control unit 85 controls the conveyance rollers 40a,
The motor 8 that drives the motor 40b is reversely rotated to automatically take out the bound sheet materials 2.

Regarding this conveyance distance, the position where the operator can easily take out the rear end of the sheet material 2 is set empirically and the number of steps of the motor 8 is set. Then, the sheet material 2 is automatically moved to the take-out position. arrive. At this time, as shown in FIG. 9(b), the entrance guide 49 and the ring-containing log guide 51 rotate clockwise so that they do not provide any resistance to the sheet material 2 with the ring 6 attached. Simultaneously with the stop of the motor 8, the solenoid 47 is turned off, the protrusion 41c is disengaged from the locking portion 46a, and the upper conveying 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. . At the same time, the work completion display is displayed on the display section 80.
will be displayed. Then, the operator takes out the bound sheet materials 2 at the take-out position.

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 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.

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 about the pin 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 pin 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 ring 6, additional stitching is required by punching 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, 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 of 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, it will not become larger than the opening amount memorized in the device 1)
0 When the work is completed, the ring 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 as shown in FIG. 16 and the ring opening button 82 is operated, the sheet material 2 can be freely removed as shown in FIG. You can freely replace them.

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 sheet material (2) that has been stitched is transported to the take-out side (arrow B) by the conveying means (5).
), the depth of the sheet material (2) used is the same as the distance between the sheet material insertion opening of the device (1) and the binding means (7). Or even if it is small, the sheet material (2) that has been stitched appears outside the device (1), and the sheet material (2) that has finished stitching appears outside the device (1).
), the sheet material automatic binding device (1)
can improve usage efficiency. Furthermore, it is possible to provide the device (1) that is easy to use even for beginners.
