Furthermore, the operating mechanism of the lower claw 56 will be explained in detail with reference to FIGS. 13 and 14. Figure 13 is a front view, and Figure 14 is a side view. A guide plate 63 equipped with a groove 62 having a horizontal part and a vertical part inside both sides of the lower claw 56 is attached to the ring opening/closing part main body 7a, so that the protrusion 65 of the lower claw 56 is guided to this groove 62. It has become. Further, a pair of oblique grooves 66 are provided in the middle portion of the main body of the lower claw 56, and an oblique protrusion 67 that slides in the oblique grooves 66 is provided on the drive plate 70 that moves up and down. This driving plate 70 is supported by the ring opening/closing part main body 7a so as to be movable up and down, and a rack 71 is provided on the driving plate 70 so that this rack 71 meshes with the terminal gear of the gear train 57 shown in FIG. It has become. Note that a presser plate 72 is provided on the front side of the lower claw 56, and this presser plate 72 and the drive plate 7
0 and the screw 7 passing through the diagonal groove 73 of the main body of the lower claw 56

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 or fixed.
Further, as shown in FIG. 15(b), when the main body 7a is tilted and fixed, the auxiliary guide 79 rotates counterclockwise around the pin 79a by an elastic member (not shown), and when the main body 7a is tilted and fixed, It is designed to shape the guide surface of the sheet material 2. Further, as shown in FIG. 17, a ring opening button 82 and a ring closing button 83 are attached to the base plate 1a of the device 1. Since the present invention is elliptical as described above, its operation will be explained with reference to FIGS. 2 and 3.

First, when automatic is selected in FIG. 2, 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 the ring 6 The sensor 61 receives the signal inserted at the same time as the magnitude signal.
The control section 85 that receives the signal from the a and 6lb sends a signal to the display section 80 to display a sheet material set display (SL). At this time, the control unit 85 controls the solenoid 1 according to the size of the link 6.
3a or 13b is turned on, and the stopper 12a 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. 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, the handle 16
When the upper limit sensor 37 is turned off due to the disappearance of the sensor lever 36a, the control unit 85 that has received the signal sends a signal to the solenoid 13a or 13 that is rising.
b to lower the stopper 12a (or 12b). At the same time, the pusher 29 is pushed downward by the handle arm 30, and the sleeve 23 is pressed down by the compression spring 2.
7a and 27b, the presser plate 26 integrated with the presser rod 25 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 perforates the bundle of sheet materials 2 on the die 10, and at the same time, the pickup arm 42 is pushed downward by the sensor lever 36b against the upward biasing force. The pickup lever 41 is lowered, and the upper conveyance roller 40b and the lever 44 press the bundle of sheet materials 2 downward with their own weight, and the control section 85, which has received a signal from the lower limit sensor 39 that is turned on at the same time, sends a signal. The solenoid 47 is turned on, the lever 41 is locked via the core rod 47a, the locking part 46a of the hook 46, and the protrusion 41c, and a handle raising operation is displayed on the display unit 80 according to a signal from the control unit 85 (S3 ) 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 17, the bundle of sheet materials 2 will be pressed down earlier than the start of perforation of the tie 10, and the sheets will be removed. Disturbance (shift) of the bundle of material 2 can be prevented. Such adjustments are made using compression springs 27a,
This can be done by adjusting 27b. Further, 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 punch 17 has already been pulled out by the handle 16 via the pusher 29. Then, after the pan chair has been completely pulled out from the sheet material 2, the push platform 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 the 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 upper conveying roller 40b is lifted up via the locking piece 41e of the lever 41 and the lever 44 by the urging force of the tension spring 41d. After the ring 6 is closed, the display section 80
A stitching completion display is displayed, and the stitching operation is completed (S4). Further, after completing the work, the operator manually pulls out the bound sheet material 2 in the opposite direction to the direction in which it was conveyed. At this time, the entrance guide 49 and the ring entrance guide 51 rotate clockwise and do not resist (see FIG. 9(b)).

Although the above has explained the normal automatic mode, the present invention operates as follows. Hereinafter, the operation of the main points of the present invention will be explained with reference to FIGS. 1(a), (b), and (c).

When the upper limit sensor 37 (see FIG. 5) or the sensor lever 36a is detected in step S4 shown in FIG. 2, the motor 8 is turned on by this signal, and the sham timer 1 is started at the same time (Sll). At this time, even if the jam timer times out, the leading edge of the sheet material 2 is detected by the paper inspection sensor 90a.
, 90b is not detected, it means that the sheet material 2 is not being conveyed as specified, and conveyance error 1 is displayed on the display section 80, the sheet material 2 is reversely conveyed, and the ring 6 is closed (312 ) Also, regardless of the jam timer 1, when the paper inspections 90a and 90b are turned on, the jam timer 2 is started. At the same time, the paper inspection sensor 90a,
90b is turned off (S13) Here, just before the jam timer 2 times up, the paper detection sensor 90
When a and 90b are turned off (S14), the motor 8 starts counting steps (S15) and counts up (
S16), the motor 8 is stopped (317). That is, the fact that the sheet material 2 has been conveyed from the leading end to the perforation section 2a at the set time means that the bundle of sheet materials 2 is not misaligned, and the stitching process is performed (818).

In step S314, if the jam timer 2 counts up (319) even though the paper inspection sensors 90a and 90b are not turned off, conveyance error 2 is displayed on the display section 80 as in step S12, and the sheet material 2 is sent backwards. Then, the ring 6 is closed (S20).

Following step S18 described above, when the stitching operation is completed, the motor 8 is rotated in the reverse direction to return the sheet material 2 to the front. Step counting is performed even when the motor 8 rotates in reverse, and even if the count is increased, the ring 6 remains on the upper claw 52 (821), or the sheet material 2 is detected by the paper inspection sensors 90a, 90b.
If it remains in the place (S22), a binding error (
S23) and is displayed on the display section 80.

Also, the sheet material 2 is reversely fed back and the paper inspection sensor 90a
, 90b are turned off, and when the sensor 11 is also turned off, the sheet material 2 has passed through these and been completely returned, and the stitching operation of the sheet materials 2 is completed. By doing this, when the sheet material 2 is misaligned, the sheet material 2 is sent back, so it is possible to prevent binding defects. Furthermore, the entrance guides 49 and 51 can prevent the leading edge of the sheet material 2 from curling or becoming disordered. Note that in the above, after the paper inspection sensors 90a and 90b detect the perforated portion 2a, the conveyance amount of the sheet material 2 is set and conveyed. However, by detecting only the leading edge of the sheet material 2, You may also set the transport amount of material 2. 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 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 drive plate 70 via the holder and always supports the lower claw 56. 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 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 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, it is necessary to perform additional stitching 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, the sheet material 2 is not automatically conveyed, so the ring 6 is opened and closed by operating the ring opening button 82 and ring closing button 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 in the control unit 85 in the same way as in the automatic mode, the operator can obtain the opening amount for the ring 6 by pressing the ring opening button 82 as many times as he deems optimal. (If you miss the ring opening button 82 too much, the device 1
(It is designed so that the opening amount will not be larger than the one you memorized.) When the work is finished, the ring close button 83 is pressed to perform a closing operation and end the work.

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 button is operated as shown in FIG. 16(b),
Sheet material 2 can be removed freely, 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) Effects of the Invention As explained above, according to the present invention, the detection means for detecting the sheet material is provided on the conveyance path intermediate the perforation means and the stitching means. The posture and conveyance state of the sheet material can be detected by the means.

In addition, if the perforation part is not detected within a predetermined time after the sheet material is detected by the detection means, the sheet material may be reversely fed by the conveyance means. It is possible to prevent binding defects due to misalignment, etc., and to perform reliable binding work.
