Abstract

PROBLEM TO BE SOLVED: To prevent a new error from generating due to an unfavorable tying or a return motion of sheet materials by a method wherein when a bending means stops in the middle of a bending of a tying member, the bending state is completed for one time before the bending means is re-started. SOLUTION: After a system error of a copying machine or pinching device itself generates, when the error is eliminated, the system of the pinching device returns to work. At this time, if clamp parts 51, 52 are under a closed state, a micro-switch M2 is turned off by the circumferential upper edge of a disk-form protruding part 90B. However, the micro-switch cannot detect whether the clamp parts 51, 52 are under a state wherein the pinching of a clip has been completed or not, and a driving motor is normally rotated as is, and for this reason, the clamp parts 51, 52 continue a motion after an interruption due to the stop as is, such as a normal motion. Therefore, if the state is before the clip is pinched, the clamp part 51, 52 are re-opened after caulking a bundle of sheet materials by the clip and placing the bundle under a bent state, and the clamp parts 51, 52 are placed under a stand-by state.

2. Description of the Related Art Some copying machines installed in offices of corporations and the like are equipped with an electric stapler for bundling copy sheets sorted in a predetermined number of copies. However, in the case of an electric stapler, in order to perform stapling, it is not possible to simply separate copy sheets so as not to mix them.

[0003] Therefore, a clamping device that is mounted on a stacking device for stacking sheet materials, such as a copying machine, a facsimile or an office printing machine, and that can automatically separate a plurality of sets of sheet materials so that they do not mix. Research is ongoing.

[0004] Such a clamping device has a pair of clamps for gripping a clip, and a jaw for engaging an end of a plate-like clip for clamping a bundle of sheet materials on opposing surfaces of the clamp. A pair of jaws are gripped at the base of the pair of jaws, a bundle of sheet materials is positioned near the gripped clips, and the pair of clamps is narrowed to bend the clips to bind the bundled sheets. The end of the material is sandwiched.

[0005] The clip is formed in an elongated rectangle.
The side edges in the width direction are connected to each other with a tape or the like to form a connecting clip. A slider is provided between the cartridge that houses the connecting clip and the pair of clamps to feed the connecting clip from the cartridge to the pair of clamps.

A drive source for opening and closing such a pair of clamps is usually provided with a DC motor and its drive circuit.
The output shaft of the DC motor is provided with a gear mechanism that is linked to open and close the clamp, and the gear mechanism is linked with a cam mechanism and a link mechanism. The drive circuit is provided with a microcomputer (hereinafter referred to as a microcomputer) and peripheral circuits. When a pinch command signal from a copying machine, facsimile, printer, or the like is sent to the microcomputer, the clamp is opened and closed to open the sheet material. Are clipped to each other with a clip.

By the way, in the case of a clamping device having such a clamp, when the clamp of the clamping device starts to bend the clip, the power supply is cut off, or the clipping device occurs in the copying machine main body. The operation may be stopped due to an error or an error generated on the clamping device side.

In such a case, if the clamp is returned to the initial open state, the clip bent in a “>” shape near the end of the sheet material is not separated from the connecting clip but floats in the air. Even if the clip is left or the clip is cut off from the connecting clip and bent at the end of the sheet material in a "U" shape, it is assumed that a loose clamping state is attached without crimping. You.

Further, when the clamp is returned to the initial state, the slider itself returns to the initial state in cooperation with the slider.
There is also a problem that the next clip interferes and jams.

Similarly, in an electric stapler, a magazine for extruding staples and an insertion end of a staple for supporting a sheet material and penetrating the sheet material are arranged along the sheet material due to power interruption or occurrence of a system error. Any of the clinchers that bend may stop operating during the bending of the staple. In such a case, when the magazine and the clincher return to the open state before the start of the staple driving again, the sheet material is discharged while the staples are being stapled, or the sheet material is further placed on the staples being driven. There is a problem that a new staple is driven in and a staple jam causes an error again.

The present invention has been made based on such knowledge, and when the bending operation of the bending means is stopped during bending of the clip or staple, after returning,
An object of the present invention is to completely prevent a binding member such as a clip or a staple that is already bending from being bent, thereby preventing occurrence of a new error due to poor binding of a sheet material or a return operation.

To explain the flow chart of 00, when the start flag rises, the micro switches M1, M2,
9, the concave portion 90 of the disc-shaped convex portion 90B of the cam 90.
It is determined whether or not A is located at the position of the microswitch M2 (S.1). This step S. In 1, if the concave portion 90A is located at the position of the microswitch M2, the initialization is unnecessary. However, if the concave portion 90A is not located at the position of the microswitch M2, the drive motor 81 is controlled to move the cam 90 to the position of the microswitch M2. Initialization is performed so that the concave portion 90A is located (S.
2).

At this time, the slider 150 moves as shown in FIG.
(1) or in the standby position shown in FIG.
01 is near the clamp portions 51 and 52.

When the concave portion 90A is located at the home position HP when the micro switch M2 is turned on from OFF to ON, the interface of the drive motor 81 is rotated forward so as to move the slider 150 from the vicinity of the photo sensor 19 to the vicinity of the micro switch M1. The signal CW (1) is sent (S.3). This forward rotation signal CW causes the drive motor 81
Rotates the cam 90. The rotation of the cam 90 swings the arm 35 via the arm 31A, and moves the slider 150 to reciprocate from the photosensor 19 to the microswitch M1.

When the drive motor 81 rotates the cam 90 in the forward direction, the elapsed time Tα from when the micro switch M2 is turned on is compared with a predetermined time T0 (S.4).

If the elapsed time Tα after turning on the micro switch M2 is longer than the predetermined time T0, it is determined whether the micro switch M2 is on or off (S.5), and the micro switch M2 remains on and does not turn off. If so, the motor lock is displayed (S.6).

When the microswitch M2 is turned off, the next elapsed time Tβ until the clip 101 is detected by the microswitch M1 is compared with a predetermined time T1 (S.7). When the elapsed time Tβ exceeds the predetermined time T1,
It is determined whether the micro switch M1 is ON or OFF (S.8). If the microswitch M1 is ON, the clip 101 is set in the clamps 51 and 52, so the drive motor 81 is rotated as it is, and the slider 150 is moved back from the clamps 51 and 52 to the photosensor 19. .

As a result, as shown in FIGS. 12A and 12B, the clip 101 is sent between the clamp portions 51 and 52. Then, the drive motor 81 rotates to close the clamps 51 and 52 (see FIGS. 12A and 3C).

, The value N of the number of reverse rotations of the drive motor 81
Is set to 0 (S.12), and the processing ends (END). Thus, the clamp portions 51 and 52 are opened as shown in FIGS.

Decision step S. In FIG. 12, if the microswitch M1 is kept OFF, FIG.
As shown in (2), clip 1 is attached to micro switch M1.
Since 01 has not reached, 1 is added to the numerical value N of the number of reverse rotations of the drive motor 81 (S.13), and ON / OFF of the photo sensor 19 is determined (S.14).

If the photo sensor 19 is ON, the number of reverse rotations N is compared with a set numerical value 10 (S.15). If the number of reverse rotations N is smaller than 10, a reverse rotation command CCW is sent to the interface of the drive motor 81. Send (S.1
6).

In response to the reverse rotation command CCW of the drive motor 81, as shown in FIGS.
Is returned to the photosensor 19 side. Here, the number of reverse rotations N is 1
If it exceeds 0, the slider 150 has reciprocated 10 times 10 times, and a signal indicating that the clip 101 is jammed is output (S.17).

The ON / OFF determination of the photo sensor 19 (S.
In 14), if the photo sensor 19 is OFF, the number N of reverse rotations of the drive motor 81 is compared with a numerical value 2 (S.18), and if the number N of reverse rotations is equal to or more than 2, the connection clip 200 is eliminated. A signal indicating the fact is output (S.19). If the number N of reverse rotations is equal to or less than the numerical value 2, the process proceeds to step S. Return to 16.

The elapsed time Tδ after sending the signal for rotating the drive motor 81 in the reverse direction is measured, and a predetermined time T3 elapses (S.20). When the elapsed time Tδ exceeds the predetermined time T3, the drive motor 81 rotates in the home position H by the reverse rotation.
Returning to P, the micro switch M2 is turned on,
It is determined whether or not it remains FF (S. 21). If the micro switch M2 remains OFF, a motor lock is displayed (S.22). If the micro switch M2 is ON, it is moved to OFF, and step S. Returning to step 1, the drive motor 81 is rotated in the normal rotation direction. As a result, as shown in FIGS. 12B and 4D, the clip 101 that has been stopped halfway is replaced with the pressing members 28 of the clamp portions 51 and 52.
Locked between the 0,280 steps.

After the clip 101 has been set on the clamp units 51 and 52, step S. After 4 FIG.
(B) (4) to (6) show a state in which the clip 101 is set to the clamp portions 51 and 52 only by re-feeding and the clip 101 bends in the same manner as in FIG. ing.

Incidentally, the initialization S.P. 2 indicates that the O of the micro switch M2 is turned on after the rise of the initialization flag.
An N.OFF determination is made (S.201). If the micro switch M2 is ON, the drive motor 81 is rotated in the reverse direction (S.202), and the micro switch M2 is turned from ON to OFF.
The elapsed time Ton-off that becomes F becomes a predetermined time Tη (approximately 600
ms) (S.203). The elapsed time Ton-off is
If it is not within the predetermined time Tη, it is displayed that the motor is locked or the sensor is abnormal (S.204). Elapsed time T
If on-off is within a predetermined time Tη, the drive motor 81
Is rotated forward (step S.205). Drive motor 81
After the normal rotation, the elapsed time Toff-on is compared with a predetermined time Tζ (approximately 600 ms) (S.206). Elapsed time Toff-
If on is within the predetermined time T #, the initialization ends. If the elapsed time Toff-on is not less than the predetermined time T $, it is displayed that the motor is locked or the sensor is abnormal (S.204).

The initialization step S. 2, if the concave portion 90A of the cam 90 shown in FIG. 7 is in the reverse-rotatable area facing the microswitch M2, the drive motor 81 is rotated reversely (arrow CCW) until the edge α comes into contact with the microswitch M2. Edge α and microswitch M2
When the micro switch M2 is turned off due to the contact with the drive motor 81, the drive motor 81 is rotated forward (arrow CW) again until the micro switch M2 is turned on again. Initialization step S. 2, the concave portion 90A of the cam 90
When the reverse rotation-impossible area in the other circumferential portion is in contact with the microswitch M2, the drive motor 81 is rotated forward until the edge α reaches the position of the microswitch M2.

Reverse rotation step S. At 16 as well, the drive motor 81 is rotated in the reverse direction (arrow CCW) until the edge α contacts the microswitch M2, and the microswitch M2 is turned off by the contact between the edge α and the microswitch M2.
F, step S. 3 and drive motor 81
Is rotated forward (arrow CW).

[Return mode control] Micro switch M2
Is to detect whether the cam 90 returns to the initial position (home position) and the clamp portions 51 and 52 are open. When the micro switch M2 is turned on to output an H-level signal to the control circuit of the drive motor 81, the clamps 51 and 52 are opened, and the slider 150 can grip the clip 101 from the side. In addition, the control circuit 300 of the drive motor 81 can select either forward rotation in the CW direction or reverse rotation in the CCW direction.

When the power supply from the copying machine or the power supply of the clipping device itself is cut off or a system error occurs in the copying machine or the clipping device itself, the power is turned on again, the power supply or the system error is eliminated. Then, the system of the clamping device is restored. When the system of the clamping device returns, the operation of the clamp units 51 and 52 differs depending on the open / close state (standby state or bent state) of the clamp units 51 and 52.

In the return mode, as shown in FIG.
First, when the micro switch M2 is turned on (signal level H) (step 1), the cam 90 is once rotated in the CCW direction in the reverse direction (step 2), and the micro switch M2 is turned off.
And becomes L level (step 3), then C
Rotate forward in the W direction (step 4), and switch M
When 2 goes to the ON H level again (step 5), the power supply to the drive motor 81 is stopped (step 6).

When the microswitch M2 hits the edge of the largest radius of the disc-shaped convex portion 90B in step 1 and is turned off to output an L-level signal, the reverse rotation of the drive motor 81 in the CCW direction is prohibited. Then, the process jumps to step 4 to perform normal rotation only in the CW direction, and when the micro switch M2 is turned on again facing the concave portion 90A (step 5), the driving of the drive motor 81 is stopped (step 6).

That is, when the clamp portions 51 and 52 are open and in the standby state, the concave portion 90A of the drive cam 90 is located at the position facing the microswitch M2, and FIG.
As shown in the figure, the micro switch M2 is ON. The drive motor 81 is reversely rotated by the microcomputer board 300 based on the ON of the micro switch M2. When the edge α on the home position side of the concave portion 90A turns off the micro switch M2 by the reverse rotation, the drive motor 81 is rotated forward based on the turning off of the micro switch M2.

After the forward rotation of the drive motor 81, when the microswitch M2 is turned on again by the edge α of the concave portion 90A,
By stopping the drive motor 81, the clamping unit 5
It returns to the open standby state before the first and the 52 receive the clip 101.

When the clamps 51 and 52 are in the closed state, the microswitch M2 is turned off by the upper peripheral edge of the disc-shaped recess 90B. At this time, the clamp 5
The micro switch M2 cannot detect whether the clip 101 is before or after the clip 101 is completely clamped. However, in order to rotate the drive motor 81 in the normal direction, the clamps 51 and 52 are The stopped operation after the interruption is continued as it is as a normal operation. Therefore,
If the clamps 51 and 52 are not clamped by the clip 101, the clamps 51 and 52 crimp the bundle S of sheets by the clip 101 into a bent state, and then open again to be in a standby state.

If the clamps 51 and 52 are stopped after being opened after the sheet bundle S is clamped and caulked by the clip 101, the clamp 5
1, 52 are opened, and the micro switch M2 is
Immediately after being turned ON by 0A, the drive motor 81 stops. At this time, the concave portion 90 is located near the microswitch M2.
The edge α of A is located.

The concave portion 90A of the disc-shaped convex portion 90B may have a small angle, but in this case, as shown in FIG. When the micro switch M2 is ON as shown in FIG. 3 in the system return of, the drive motor 81 is stopped as it is. Also, the microswitch M
If 2 is OFF, the drive motor 81 is rotated forward, and the drive motor 81 is stopped when the micro switch M2 is turned ON next time.

In any case, the clamp 5
If the sheet material bundle S exists between 1 and 52, the sheet material bundle S is swaged by the clip 101, and the sheet material S
If the bundle does not exist, the clip 101 falls from between the clamp portions 51 and 52 in a bent state.

Here, the standby state and the bending state of the clamp portions 51 and 52 are detected by the disc-shaped convex portion 90B, the concave portion 90A and the microswitch M2.
0B is formed by a disk, a notch corresponding to the concave portion 90A is formed in the disk, and a photosensor such as an interrupter or a phototransistor is provided on both sides of the disk.
The bending state may be detected.

Although the open / close state of the clamps 51 and 52 is related to the clip feed operation of the slider 150, the microswitch M is located between the clamps 51 and 52.
1, the micro switch M1 can detect the presence or absence of the clip 101 when the power is restored.

Even when the micro switch M1 is ON at the time of return, the edge β of the disc-shaped convex portion 90B on the side of the feed completion position has passed through the micro switch M2, so that the micro switch M2 is OFF and becomes L level, The drive motor 81 enters the region where reverse rotation is impossible, and rotates forward as it is. At this time, the swing of the arm 35 in the clip feed direction has been completed. The arm 35 has a cylindrical portion 34 and the first link member 31 which are connected to each other so as to be rotatable relative to each other.
6 so that the clip 101 is in contact with the stopper 24 and the microswitch M1, the arm 35 is
Even if the first link member 31 rotates so as to press 0, the torsion of the first link member 31 is absorbed by the spring 70, and the arm portion 35 does not rotate.

As a measure to reduce the inertia during the rotation of the motor and to eliminate the overrun of the clamping operation, the clip 101 is moved from the home position during the forward rotation.
Is completed (between the edge α and the edge β of the concave portion 90A) is set to 12V, and the drive motor 81 is driven at a voltage of 24V when the voltage exceeds the feed completion position β of the clip 101. On the other hand, when the drive motor 81 passes through the concave portion 90A during the reverse rotation, the clamp operation due to an increase in inertia is controlled by performing voltage control of driving with a voltage of 6V.

[Operation] Next, the mechanical operation of the clamping device will be described generally.

First, the lid 120 of the cartridge 100 is opened, and the connecting clip 200 is put into the storage chamber 102.

Next, the distal end of the connecting clip 200 is positioned outside the cartridge 100, guided between the slider 130 and the cartridge body 103, the cover 120 is closed, and the cartridge 100 is moved to the table 13 of the apparatus body 11.
Attach to.

Before the drive motor 81 is driven, the drive cam 85 and the cam 90 are in a standby state shown in FIG.
The slider 150 is at the home position shown in FIG.
The sensor 19 is connected to the connecting clip 20 of the cartridge 100.
By detecting the tape 201 of No. 0, the presence of the clip 101 is detected. The micro switch M2 is a cam 9
0 concave portion 90A is detected, and the clamp members 51 and 5 are detected.
2 is open at the home position shown in FIG.

In this state, when a pinch signal is output from a copying machine main body or the like (not shown) and the sheet bundle S is placed on the upper surface of the outer wall 22 and the front wall 21 of the housing 12, the microcomputer board 300 Photo sensor 19 is clip 10
1 is detected, the drive of the drive motor 81 is controlled based on the pinch signal. The drive of the drive motor 81 causes the drive cam 85 to rotate clockwise (direction A in FIG. 6).

When the tip of the arm 33 of the first link member 31 enters the small diameter portion of the cam groove 86 by the rotation of the driving cam 85, the arm 33 of the first link member 31 and the second link member 32 are separated. The arm portion 35 of the second link member 32 rotates in the CW direction in FIG. With the rotation of the arm 35, the slider 150
It moves from the 9 side to the micro switch M1 side.

The movement of the slider 150 causes the advance claw 18 to move.
The leading end of the clip 101 is caught by the leading clip 101, and the clip 101 is sent to the clamps 51 and 52 as the slider 150 moves. At this time, slider 1
If the rearward pawl 195 is caught by the other clip 101, the connecting clip 20
0 will be sent out.

Since the clips 101 are connected by the tape 201, the clips 101
From 00, it is sent to the clamp units 51 and 52 side.

Further, when the driving cam 85 rotates and the arm 33 of the first link member 31 comes near the minimum diameter of the cam groove 86, the slider 150 further moves to the left to move the clip 101 to the stopper 24. Send out to the contact position. When the clip 101 comes into contact with the stopper 24, the movement of the slider 150 stops, and the clip 101 is held by the projections 73B and 77B of the clamp members 51 and 52. Then, the micro switch M1 is connected to the clamp members 51 and 52.
Is detected.

When the distal end of the arm 33 of the first link member 31 reaches the minimum diameter of the cam groove 86, the first link member 31 further rotates, but the slider 150 is stopped by the stopper 24. Therefore, only the first link member 31 is opposed to the second link member 32 against the urging force of the spring 36.
Relative to.

The amount of rotation of the first link member 31 is set so that the slider 150 moves a distance larger than the width of the clip 101. Even if the gap between the clips 101 varies, the first link member 31 can rotate. As the link member 31 rotates relative to the second link member 32,
Since the variation is absorbed, the clip 101 can be reliably sent out to a predetermined position.

Further, when the drive cam 85 rotates and the tip of the arm 33 comes from the minimum diameter portion of the cam groove 86 to the large diameter portion, the first link member 31 rotates back. The second link member 32 is moved in the same direction with the first link member 31.
Rotates, and the slider 150 returns to the home position on the photosensor 19 side.

When the slider 150 returns to the home position, the clip 101 is prevented from returning together with the slider 150 by the check pawl attached to the guide plate 130 of the apparatus main body 11. Since the check pawls are provided above and below the guide plate portion 130, the clip 101 does not tilt when the slider 150 returns.

On the other hand, the cam 90 rotates together with the driving cam 85, and the small diameter portion of the cam 90 corresponds to the small diameter portion of the cam groove 86 of the driving cam 85. Therefore, when the slider 150 reciprocates, the shaft 62 is in contact with the small-diameter portion of the cam 90, and the clamp members 51 and 52 remain open as shown in FIG.

Then, when the driving cam 85 further rotates and the arm 33 moves along the large-diameter portion of the cam groove 86 and the shaft 62 comes into contact with the peripheral surface of the enlarged portion R2 of the cam 90, the clamp pivots. The member 53 rotates clockwise B about the shaft 63 as a fulcrum. With this rotation, the clamp members 51 and 52 close, and by this rotation, the clip 101 is bent in a U-shape while being pushed forward.

Further, when the driving cam 85 rotates and the shaft 62 of the clamp rotating member 53 comes into contact with the large-diameter portion R3 of the driving cam 90 on the peripheral surface of the increasing portion R2, the clamping portion is further moved. Since the clips 51 and 52 rotate in the closing direction, the clip 101 is folded in a folded state.

At this time, with the front end of the pressing member 280 pressing the clip 101 from above and below, the clamp member 5
The clips 1 and 52 crimp the bent portion of the clip 101, so that the clip 101 is in close contact with the sheet bundle S and is bent to sandwich the sheet bundle S. That is, the both ends of the clip 101 are prevented from floating from the sheet bundle S, and the sheet bundle S can be securely pinched and bound.

When the driving cam 85 rotates and the shaft 62 of the clamp rotating member 53 comes into contact with the peripheral surface of the reduced portion R4 of the driving cam 90, the clamp rotating members 53 and 54 use the shaft 63 as a fulcrum. To rotate counterclockwise, and clamp member 5
1, 52 rotates in the opening direction opposite to the above. Then, when the driving cam 85 and the cam 90 make one rotation, the clamp members 51 and 52 return to the home positions shown in FIG. 7, and the micro switch M2 detects the concave portion 90A of the cam 90 and the driving of the driving motor 81 is stopped. .

As described above, the sandwiching device 10 of this embodiment binds the bundle S of the stacked sheet materials by bending the clip 101 which is a linear or plate-like binding member. A clamp part 51 as a pair of bending means,
52, and the clamp portions 51, 52
Is a stacking device for a stacked body having a standby state in which the clip 101 is opened to stand by and waits, and a bent state in which the clip 101 is closed to bend and the bundle S of sheet materials is bound. The clamping device 10 includes a clamp 51,
When the clip 52 is restarted after the cause of the stop when the clip 101 stops in the middle of bending of the clip 101, the clamp 5
It is characterized in that a step is provided in which the bending states of the first and second bending sections 1 and 52 are completed and then the standby state is set.

According to the clamping device 101, when the clamp portions 51 and 52 stop in the middle of the bending operation of the clip 101, the clamp portion 5 stopped in the bent state after returning.
Since the bending state of the first and second bendings is completed, errors such as a poor binding of the sheet material bundle S and a jam due to the double feeding of the clip 101 are prevented.

Particularly, in this embodiment, the clamp 5
1 and 52 are just after the start of bending and the clip 101
If the bending state of the tape remains weakly connected by tape,
The clip 101 is prevented from floating in the air. The clip 10 bent in a “U” shape due to interruption of power supply to the clamping device 10 or occurrence of a system error.
Even if the sheet 1 loosely adheres to the sheet bundle S and the sheet bundle S is not completely bound, the clamp portions 51 and 52 are once completely closed, so that the bundle S is completely bound by the clip 101 and The occurrence of poor wearing is prevented.

According to the clamping device 10 of this embodiment, when the clip 101 is not set on the clamps 51 and 52, the microcomputer board 300
The slider 150 is operated to send the clip 101 a predetermined number of times, and the clip 101 is
1, 52, the clamp parts 51, 5
2 can be prevented from bending. Therefore, it is possible to prevent the sheet material S from being damaged due to the void, the clamp portions 51 and 52 from being damaged, and the like.

Further, the connecting clip 2 of the slider 150
The number of feeding operations of 00 is counted, and if the clip 101 is not set in the clamp units 51 and 52 within the counted number, a state where the clip 101 is not set is displayed on an operation panel of a copying machine or the like, and the operator is notified. I can let you know. The photosensor 19 detects that there is no connecting clip 200 in the cartridge 100, and
When the microswitches M1 on the sides 1 and 52 detect that the clip 101 is not present, the output from the microcomputer board 300 indicates that the connected clip 200 is not present on the cartridge side, and can instruct replenishment. If there is no clip 101 in the cartridge 100 and there is no clip 101 in the clamps 51 and 52, and if the clip 101 is not detected in the clamps 51 and 52 even after the slider 150 is fed a predetermined number of times, the microcomputer board 300 Can indicate that the clip 101 is jammed in the moving area of the slider 150.

In the above embodiment, the cartridge 100 of the clamp device 10 has been described. However, the present invention is not limited to this, and it is needless to say that the present invention can also be applied to an electric stapler cartridge.

FIG. 13 is a schematic view of an electric stapler to which the present invention is applied. The electric stapler 400 generally includes a magazine unit 410 and a clincher unit 420. On the base 411 of the magazine unit 410, a cartridge 41 in which a number of straight staples 401 are arranged in parallel and sheet staples 402 connected by an adhesive are stacked.
2 are provided. A pair of links 430 are provided on both sides of the cartridge 412, and the links 430 can rotate around a fulcrum shaft 431 near the center of the cartridge 412. At one end of the link 430, a roller 432 serving as a cam follower is provided. The link 430 is urged by a tension spring 435 so that the roller 432 side is located below, and is supported by a stopper 436.

At the other end of the link 430, a flat driver 433 that pushes the staple 401 bent into a rectangular gate shape toward the clincher 420 is supported. The driver 433 includes a shaft 430 of the link 430.
A flange having a long hole through which A is inserted protrudes, and the driver 433 moves up and down by the vertical movement of the shaft 430A.

A guide plate 413 for guiding the staple 401 is provided upright on the base 411 near the driver 433, and the driver 433 moves up and down along the guide plate 413. On the surface of the driver 433 opposite to the guide plate 413, a forming plate 434 that cuts the staple 401 from the front end of the sheet staple 402 and bends both ends into a rectangular gate shape is slidably provided. I have.

The forming plate 434 also has a shaft 430A.
, And both sides of the lower end of the forming plate 434 protrude below the center of the lower end.
A convex portion 416 that supports the central portion of the staple 401 is formed in a portion of the base 411 below the forming plate 434. Both sides of the protruding portion 416 are tapered surfaces 417 for moving the staple 401 bent in the gate shape to the lower side of the driver 433 while the lower end both sides of the forming plate 434 enter. Next to the forming plate 434, the guide plate 4
14 is erected. A guide plate 414 supports the front end of the sheet staple 402.

The driver 433 and the forming plate 4
34 moves up and down at the same time, and the lower end of the driver 433 projects below the lower end of the forming plate 434. When the driver 433 and the forming plate 434 are lowered by the link 430, the front end of the sheet staple 402 hits the side surface of the driver 433 and stops moving, and the sheet staple 402 is bent into a gate shape by the lowering of the forming plate 434.

Next, when the driver 433 and the forming plate 434 are raised, the staple 401 bent in a gate shape moves below the lower end of the driver 433, and the next staple is located below the forming plate 434. ing.

Accordingly, in the completely initial state immediately after the sheet staple 402 is set in the cartridge 412, the staple 401 is not provided at the lower end of the driver 433, but the front end of the sheet staple 402 is disposed below the cartridge 412. It is pushed by a plate-like hook member (not shown) provided and abuts against the side surface of the driver 433.

Therefore, at the first time, the staples at the front end are bent into a gate shape by the forming plate 434 and separated from the sheet staples 402.
When the driver 433 and the forming plate 434 rise, the staple 401 bent in a gate shape falls along the tapered surface 417, and the guide plate 4
13 and stops on the side surface of the convex portion 416. When the driver 433 descends for the second time, the side of the convex portion 416 and the guide plate 4
The staple 401 stopped in the gap with the staple 13 is pushed by the driver 433 and protrudes toward the clincher 420.

Roller 43 of link 430 of base 411
On the second side, a rotating shaft 440 is provided, which is supported by a side wall provided upright on the base 411.
Are attached integrally. The cam 441 is a rotary shaft 44
The gear 442 is driven by a motor 450 via gears 443, 444, 445.

The rotation of the motor 450 is controlled by a drive circuit (not shown). That is, when the copy paper T is placed on the table 421 of the clincher unit 420, the motor 4
The rotation of the cam follower 43 causes the cam follower 43 to rotate.
2 is pushed up and the driver 433 descends. The driver 433 descends and the staple 401 projects from the end of the base 411 as described above.

The clincher 420 has a table 421
It has. A slit-shaped opening 421A is formed at a position where the driver 433 of the table 421 is lowered. Below the opening 421A, as shown in FIG. 14, a pair of clincher arms 422 that bend the ends 401A of the gate-like staple 401 inward are provided. The clincher arm 422 is held by a shaft 422A, and the shaft 422A is rotatably held by the clincher frame 423. The clincher arm 422 is urged downward by a tension spring (not shown). The clincher arm 422 is vertically rotated by the link 424.

At one end of the link 424, a horizontal flange portion 424A is formed, and at the other end of the link 424, a cam follower 425 is provided. Link 4
Reference numeral 24 is rotatably supported by a shaft 424B provided on the side wall of the clincher frame 423. The link 424 has its cam follower 425 side urged downward by a spring. Cam follower 425 is cam 426
It moves up and down. The cam 424 includes gears 427A and 42
Driven by a motor 428 via 7B and 427C. The motor 428 is controlled by a control circuit (not shown), and when the driver 433 descends and the cam follower 432 abuts on the same radius 441A of the cam 441, the link 424 is moved up and down so that the end of the staple 401 becomes a sheet material. Bend along the paper of T.

In this electric stapler 400, when the front end of the sheet staple 402 only contacts the side surface of the driver 433 and the lower end of the forming plate 434 is above the front end of the sheet staple 402, the lower end of the forming plate 434 is While not contacting the front end of the sheet staple 402, the link 4
It is possible to slightly swing 34. That is, it is possible to rotate the drive motor 450 in the forward and reverse directions.

Therefore, when the electric stapler 400 stops with the lower end of the forming plate 434 not in contact with the front end of the sheet staple 402, the drive motor 450 is rotated and adjusted in the forward and reverse directions to adjust the link 433.
Can be located at the regular standby position. In addition, since the area where the forming plate 434 is in contact with the front end of the sheet staple 402 is constant due to the angle of the cam 441, the electric stapler 4 can be used while the forming plate 434 is in contact with the sheet staple 402.
When 00 stops, the driver 433,
The forming plate 434 is lowered, and the end 401A of the staple 401 is bent at the clincher 420. In order to provide the standby position and the bent position of the link 430 at the rotation angle of the cam 441, the rotation shaft 440 is used.
Can be identified by attaching a disk having a notch at a predetermined angle to the disk. Therefore, by providing an interrupter and a photo sensor on both sides of this disc, the link 43
It is possible to detect whether 0 is a standby state or a bent state.

With this configuration, the link 4
When the system 30 is stopped in the standby state or the bending state due to a system down, etc., and is returned after the cause is eliminated, the staple 401 is hit twice or the staple 401 of the sheet bundle T is stapled and ejected without being completed. Can be prevented.

According to the clamping device of the first aspect of the present invention,
During the bending operation of the clamp, for example, as a result of an interruption cause such as a cutoff of a power source which is a power source of the clamp or an error, the bending operation of the clamp is interrupted, and the clamp maintains the posture at the time of bending. If the pair of clamps are once returned to the initial open state when the opening / closing operation is performed again after eliminating the cause of the interruption, a “U” -shaped clip that is not completely bent depending on the stop state of the bending is obtained. The sheet bundle may be loosely attached to the end of the sheet bundle, and the sheet bundle may not be completely bound. However, according to the present invention, even if the “U” -shaped clip that is not completely bent is stopped while loosely attached to the end of the paper bundle, the clamp is completely closed once, so that the paper bundle is As a result, the sheets are completely stapled, and the occurrence of poor clamping is prevented.
