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

First, when automatic is selected in FIG. 2(a) and the finger of the ring 6 is inserted into the upper claw 52, the sensor lever 6° rotates counterclockwise around the shaft 60a, and the size of the ring 6 is adjusted. The sensors 81a and 61b detect the signal when the ring 6 is inserted at the same time as the signal.
The control unit 79 sends a signal to the display unit 80 to display the sheet material set (Sl). At this time, the control section 79 turns off the solenoid 13a or 13b depending on the size of the ring 6 until the stopper 12a or 12b protrudes into the through hole 10b of the die 10. Then, the sheet material 2 comes into contact with the stopper 12a or 12b. insert. The control unit 7 receives a signal from the sensor 11 detected at the same time.

At the same time, the pusher 29 is pushed downward by the handle arm 30, the sleeve 23 descends against the compression springs 27a and 27b, and the presser plate 26 integrated with the pusher bar 25 presses the bundle of sheet materials 2. The lowered presser plate 26 then locks the lock plate 3.
It is locked by the claw 31a of No. 1. At the same time, the bunch air descends and perforates the bundle of sheet materials 2 on the die 10, and at the same time, the pickup arm 42 resists the upward biasing force and is pressed downward by the sensor lever 36b. The lever 41 is lowered, and the main conveyance roller 40b and the lever 44 press the bundle of sheet materials 2 downward with their own weight. At the same time, the control unit 79 receives a signal from the lower limit sensor 39, which is turned on, and sends a signal to the solenoid. 47 is turned on, the lever 41 is locked via the core frame 47a, the locking part 46a of the hook 46, and the protrusion 41c, and the handle raising operation is displayed on the display unit 80 by a signal from the control unit 79 (8
3) At this time, press the presser plate 26 before the tip of the bunch 17.
If the lower surface of the sheet material 2 is pressed against the bundle of sheet materials 2,
It is possible to press down the bundle of sheet materials 2 earlier than the start of perforation by the die 1o, 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 79 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 bunch air is completely pulled out from the sheet material 2, the pusher 29 rises, and the lock plate rotates counterclockwise around the bin 32 via the arm 35 and the release link 33. Claw 3 that is locked

When the control unit 79 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. The ring entrance guide 51 is conveyed to the opening/closing section 7, and the ring entrance guide 51
This prevents the leading end of the bundle of sheet materials 2 from being disturbed, and after stopping at a suitable position relative to the open link 6 shown in FIG. 12, the ring 6 closes. In addition, upon receiving the signal to stop the stepping motor 8, the control section 79 sends a signal to turn off the solenoid 47, so that the protrusion 41c moves to the locking section 48.
a, and the main conveyance roller 40b is lifted via the lever 44 of the locking piece 41e of the lever 41 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.

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 70 and descends. Then, the oblique protrusion 67 of the guide plate 70 connects to the lower claw 56 via the oblique groove 66.
Give the component force on the right side in the figure. Then, the protrusion 65 of the lower claw 56 is guided by the horizontal part of the groove 62 of the guide plate 63.
The lower claw S6 moves to the right and becomes capable of engaging with the fingers of the ring 6, and is then guided by the downward force to the vertical part of the groove 62, and the lower claw S6 descends and engages the fingers of the ring 6 downwards. Open to.

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 7.
5 and is integrated with the drive plate 69 to constantly hold 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.

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

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

Next, set the manual mode to Fig. 1, Fig. 2(b), Fig. 15,
This will be explained with reference to FIG. 16 as well. This is manually operated device 1.
is used.

A pin 76 is provided at the lower right side of the ring opening/closing part main body 7a to rotatably support the main body 7a on the base plate 1a, and a microswitch 77 that turns on and sends a signal when the main body 7a is tilted and fixed is provided. It is provided. Additionally, a ring opening chain and a ring opening button are provided. Incidentally, the tilting fixing mechanism of the main body 7a may be a rail-type stopper, a magnetic adsorption type, or the like.

Next, the operation of the manual mode will be explained with reference to the flowchart of FIG. 2(b).

As shown in FIG. 15, when the main body 7a of the ring opening/closing part 7 is tilted and fixed, the manual selection state shown in FIG. 79 switches the control system to manual mode (2) shown in FIG. 2(b). At step 1, a message will appear prompting you to set the ring.

When the setting of the ring 6 is completed and it is determined that the ring 6 has been set, the process advances to step , and a display prompting the setting of the sheet material 2 appears. After sheet material 2 is set,
It is detected whether or not the sheet material 2 has been set, and the process proceeds to step 3, where an operation display for operating the handle 16 is performed in order to encourage perforation of the sheet material 2. When a hole is punched and drilled by operating the handle, it is confirmed that the handle 16 has been operated because the lower limit and upper limit sensors 39 and 37 detect this order. Then step 4
The controller 79 controls the motor 5 by combining the signals from the sensors 39 and 37 and the signal from the aperture variable resistor 85.
5 and 59 to open the ring 6 by the required amount.

The opening amount of the ring 6 is determined by the operator operating the variable resistor 85 in advance based on the thickness of the sheet material 2 and the size of the ring 6. After that, the perforated sheet material 2
Insert the ring 6 into the ring 6 and press the closing button 81.
is closed to complete the binding.

In addition, since the bundle of sheet materials 2 is thick, if you want to bunch them in several batches, insert the first sheet material 2 into the ring 6, then bunch the second sheet material 2, and then stack the first sheet material 2.
Insert it into the ring 6 from above. When the sheet material 2 of the desired thickness is inserted into the ring 6 by repeating this several times, the closing button 81 is pressed.

After perforating the toothpick sheet material 2, the ring 6 is automatically opened only during the first perforation, and the ring 6 remains open until the closing button 81 is pressed.

Therefore, during the second and subsequent drillings, step 4 is omitted and the process proceeds to step Ks. In this step 2,
The opening amount of the ring 6 can be automatically changed according to the amount by which the operator turns the opening amount variable resistor 85 left and right. Therefore, if the operator determines that the opening amount of the ring 6 is insufficient and the second seal 1-material 2 cannot be inserted, in this step, the variable resistor 85 is operated to insert the ring 6. All you have to do is open it further.

Next, in step 6, if the sheet material 2 to be perforated for the third time or later is set, steps K 3 and K
Repeat s and if necessary, press K to open the ring further.

If the sheet material 2 is not set in step 6, the process proceeds to step 7, where the ring 6 is closed using the closing button 81, and the stitching operation is completed.

(g) As described in detail, according to the present invention, in the manual mode of the sheet material stitching device (1), the first sheet material (
2) Signal of completion of drilling work and opening amount setting means (85)
