Further, as shown in FIG. 15, the main body 7 of the ring opening/closing part 7
A pin 76 is provided to rotatably support the main body 7a on the base plate 1a, and a microswitch 77 is provided which turns on and sends a signal when the main body 7a is tilted and fixed.

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. Further, as shown in FIG. 17, a ring opening 82 and a ring opening 83 are attached to the base plate 1a of the device 1.

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

First, select AUTO in Figure 2 and select 1. When the input switch 81 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 receives the inserted signal at the same time as the size signal of the ring 6. sensor 6
The control unit 85 that receives signals from 1a and 61b sends a signal to the display unit 80 to display a sheet material set display (Sl). At this time, the control section 85 turns on the solenoid 13a or 13b depending on the size of the ring 6, so that the stopper 12a or 12b protrudes into the through hole 10b of the die 10. Next,
Insert the sheet material 2 until it contacts the stopper 12a or 12b. At the same time, the control unit 85 receives a signal from the sensor 11 and sends a signal to the display unit 80 to display a handle lowering operation (S2). Next, handle 1
6 is lowered, and the upper limit sensor 37 is connected to the sensor lever 36a.
When the controller 85 is turned off due to the disappearance of the
sends a signal and the solenoid 13a or 1 is rising.
3b to lower the stopper 12a (or 12b). At the same time, the push bar 29 is pushed downward by the operator via the handle arm 30, the sleeve 23 descends against the compression springs 27a and 27b, and the push bar 29
A presser plate 26 integrated with 5 presses the bundle of sheet materials 2. The lowered presser plate 26 is then locked by the claw 31a of the lock plate 31. At the same time, the bunch 17 descends and the die 10
The upper bundle of sheet materials 2 is perforated, and at the same time, the pickup arm 42 resists the upward biasing force and moves the sensor lever 36b.
As the pickup lever 41 is pressed downward by The control unit 85 that received the signal sends a signal, the solenoid 47 is turned on, and the lever 41 is activated via the core frame 47a, the locking part 46a of the hook 46, and the protrusion 41c.
is locked, and the display section 8 is locked by a signal from the control section 85.
At this time, if the lower surface of the presser plate 26 presses the bundle of sheet material 2 before the tip of the punch 17, the hexagonal lift operation is displayed at 0 (S3). It is possible to quickly press down the bundle of sheet materials 2 and prevent the bundle of sheet materials 2 from being disturbed (shifted). Such adjustment can be made by adjusting the compression springs 27a, 27b.

Moreover, even if the presser plate 26 quickly presses the bundle of sheet materials 2, the compression springs 27a and 27b are present, and it is possible to prevent excessive compressive force from being applied to the presser rod 25 and the sleeve 23.

Next, raise the handle 16 and press the sensor lever 36b.
Upon receiving the signal 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 36a turns on the upper limit sensor 37, the bunch 17 has already been pulled out by the handle 16 via the push platform 29. Then, when the punch 17 is completely pulled out from the sheet material 2, the pusher 29 rises, and the lock plate 31 is moved to the pin 32 via the arm 35 and the release link 33.
The holding plate 26 is rotated counterclockwise around , the holding plate 26 is released from the locked claw 31a, and the holding plate 26 is separated from the bundle of sheet materials 2. Then, the control unit 85 receives a signal that turns on the upper limit sensor 37, and sends a signal to the conveyor rollers 40a, 40.
When the stepping motor 8 that drives the sheet material 2 is turned on, the sheet material 2 is transported to the ring opening/closing section 7 by the transport rollers 40a and 40b for a certain number of pulses, and the leading end of the bundle of sheet materials 2 is prevented from being disturbed by the ring entrance guide 51 along the way. is,
After stopping at 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, so that the protrusion 41c moves to the locking section 46a.
The lower conveying roller 40b is lifted up via the locking piece 41e of the lever 41 and the L/bar 44 by the urging force of the tension spring 41d. After the ring 6 closes, the display section 8
A stitching completion display is displayed at 0, and the stitching operation is completed (34).

Then, upon receiving the signal that the motors 55 and 59 for opening and closing the ring 6 close the ring 6 and stop, the control section 85 sends a signal to instruct the motor 8 to reverse rotation, and at the same time turns on the solenoid 94. When the ring 6 of the sheet material 2 bound by the ring 6 approaches the rollers 40a and 40b, the solenoid 47 is turned off and the hook 46 moves to the protrusion 4.
1c, and the motor 8 stops at the same time as the roller 40b separates from the roller 40a (see FIG. 5). after that,
Due to gravity and inertia, the bundle of sheet materials 2 falls into the storage section 93 and is loaded, and the work is completed (S5). At this time,
The entrance guide 49,51 rotates clockwise so that it does not resist the bundle of sheet material 2. Next, the operation of the lower pawl 56 will be explained with reference to FIGS. 13 and 14. When the drive plate 70 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 downward like the fingers of the ring 6. 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.

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 binding capacity of the ring 6, it is necessary to perform multiple punches and perform additional binding. 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. Since the opening amount for the ring 6 is memorized by the control section 85 as in the case of automatic mode, 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 too large, the device 1
(It is designed so that the opening amount does not become larger than the one memorized in the previous step.) 0 When the work is completed, the ring opening silver 83 is pressed to perform the 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 is adjusted as shown in FIG. 16(b),
Only sheet material 2 can be removed, and sheet material 2 can be added/added.
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 conveying means automatically conveys the bundle of sheet materials for which the stitching operation has been completed to the storage section and stores the bundle, so that the work is easy. each time,
It becomes possible to perform the next sheet material stitching operation without taking out the sheets, thereby improving work efficiency and reducing loss of work time.
