Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip device for binding the ends of a sheet bundle.

[0002]

2. Description of the Related Art Conventionally, an electric stapler for binding an end portion of a sheet bundle has been known. Instead of the electric stapler, a clip device for bending an end portion of the sheet bundle by bending a flat binding member is proposed. Has been done.

Such a clip device is housed in the cartridge, and a device main body having a clamp means for bending the binding member, a cartridge containing a connecting and sandwiching body in which a plurality of flat binding members are connected by a tape in a band shape, and a cartridge. And a slider for sending out the front end portion of the connecting and sandwiching body.

Each time the slider reciprocates, the binding member at the tip of the connecting and sandwiching member is sent to the clamp means.
This binding member is bent by the clamp means to bind the end portion of the sheet bundle.

[0005]

By the way, the connecting and sandwiching body is formed by connecting a plurality of flat plate-like binding members in a band shape by tapes, and the gap between the binding members varies. For this reason, the distance L1 by which the slider reciprocates L + the distance L1 of the binding member and the width ΔL1 of the gap are added.
Even if it is set to L1, there is a problem that if there is a portion where the width ΔL2 of the gap is larger than ΔL1, the binding member cannot be reliably delivered to the clamp means. Also △
If L1 is set as the maximum value of variation, there is a problem that the slider feeds the binding member too much.

If a stopper is provided to stop the slider when the binding member is fed to a predetermined position, the slider is stopped in the course of forward movement, and the drive means for reciprocating the slider is locked in the middle. The problem arises.

The present invention has been made in view of the above problems, and an object thereof is to reliably feed the binding member to a predetermined position and to prevent the driving means for reciprocating the slider from locking. Not to provide a clip device.

[0008]

In order to achieve the above-mentioned object, the present invention provides a cartridge containing a connecting and sandwiching body in which a plurality of binding members are connected by a tape in a band shape, and Sending means for sending to the binding position by reciprocating the leading end of the connecting and sandwiching member, and bending the binding member at the leading end sent to this binding position and separating the binding member from the tape to end the sheet bundle. And a link driving means for operating the linking means, wherein the sending means moves forward by the linking means. When the link driving means is driving forward so that the feeding means is moved forward when the binding member is fed to the binding position and stopped, the feeding drive is absorbed to stop the feeding means. Characterized in that it comprises absorbing means allowed to the.

According to a second aspect of the present invention, the link means is a reciprocating link member for reciprocating the sending means, and the reciprocating link member is operated by the driving of the link driving means, and is relatively movable with respect to the reciprocating link member. The drive means is composed of a drive link member, and the absorbing means is a spring connecting the reciprocating link member and the drive link member, and the drive link member is opposed to the reciprocating link member against the urging force of the spring. It is characterized by moving.

[Operation] Next, the operation of the sandwiching device configured as described above will be described.

First of all, as shown in FIG.
The cartridge 100 storing 0 is mounted on the table 13 of the apparatus main body 11. When the cartridge 100 is mounted on the table 13, the lock member 115 moves to the position shown by the broken line in FIG. 15 and the slider 150 is unlocked. In addition, the locking protrusion 36 of the arm portion 36 of the moving mechanism 30.
A is guided by the guide portions 157, 157 of the slider 150 and inserted between the locking portions 158, 158.

Before the drive motor 81 is driven, the drive cam 85 and the cam 90 are in the initial positions shown in FIGS. 9 to 11 and 14, and the slider 150 is shown in FIGS.
It is in the home position shown in. The sensor 26 detects the presence of the sandwiching plate 101 by detecting the tape 201 of the connecting and sandwiching body 200 in the transport path 113 of the cartridge 100. Further, the micro switch M2 detects the concave portion 90A of the cam 90, and the clamp members 51 and 52 are located at the home positions shown in FIGS.

Then, the sheet bundle S is placed on the step portion 28A of the outer wall 28 of the housing 12 and the upper surface Va of the front wall portion V.

In this state, when a sandwiching signal is output from the copying machine main body or the like (not shown), the control circuit detects that the sandwiching plate 101 is present by the sensor 26. Drive control of the drive motor 81 is performed. By driving the drive motor 81, the drive cam 85 rotates clockwise (counterclockwise in FIGS. 7 and 9 and FIG. 8) via the gear 83 and the reduction gear train 84.

When the tip end portion 31b of the arm portion 31A of the first link member 31 enters the small diameter portion 86A of the cam groove 86 by the rotation of the drive cam 85, the arm portion 31A of the first link member 31 moves clockwise in FIG. (Counterclockwise in FIG. 2). The second link member 32 rotates together with the first link member 31, and the arm portion 36 of the second link member 32 rotates in the arrow direction (counterclockwise direction) in FIG. With the rotation of the arm portion 36, the slider 150 moves leftward (in FIGS. 1 and 2).

By the movement of the slider 150, as shown in FIG. 17, the front end portion 181a of the front feeding claw 181 is moved to the conveying path 11.
It is caught by the leading sandwiching plate 101 ′ in FIG. 3, and the sandwiching plate 101 ′ is sent to the tip side as the slider 150 moves. At this time, if the rear feeding claw (not shown) of the slider 150 is caught by another sandwiching plate 101, the front feeding claw 181
Then, the sandwiching plates 101 ', 101 are sent out by the rear feeding claw.

Since the sandwiching plates 101 are connected by the tapes 201, the sandwiching plates 101 in the transport path 113 are sent forward (to the left in FIGS. 1 and 2) and sandwiched in the storage chamber 102. The landing plate 102 will be sent out to the transport path 113 side.

Further, the drive cam 85 is rotated so that the tip end portion 31b of the arm portion 31A of the first link member 31 is moved into the cam groove 8.
When it comes close to the minimum diameter portion 86d of 6 (see FIG. 9), the slider 150 further moves to the left and sends the sandwiching plate 101 ′ to the position where it comes into contact with the stopper 29. Sandwich plate 10
When 1'abuts on the stopper 29, the movement of the slider 150 stops, and the sandwiching plate 101 'is held by the projections 73B and 77B of the clamp members 51 and 52. Then, the micro switch M1 detects the sandwiching plate 101 'held by the clamp members 51 and 52.

Then, the arm portion 3 of the first link member 31.
When the tip portion 31b of 1A reaches the minimum diameter portion 86d of the cam groove 86, the first link member 31 further rotates clockwise (counterclockwise in FIG. 2) in FIG. 12, but the slider 150 stops the stopper 29. Therefore, only the first link member 31 rotates relative to the second link member 32 against the biasing force of the spring 37. That is, the spring 37 absorbs the forward drive of the drive cam 85.

The rotation amount of the first link member 31 depends on the holding plate 1
The slider 150 is set to move a distance larger than the sum of the width of 01 and the width of the maximum gap between the sandwiching plates 101, 101. Therefore, regardless of the size of the gap between the sandwiching plates 101, the sandwiching plate 101 can be reliably delivered to a predetermined position. Further, since the first link member 31 rotates relative to the second link member 32, even if the slider 150 stops during the forward movement of the first link member 31, the driving cam 85
Can rotate without locking.

Further, when the drive cam 85 rotates and the tip end 31b of the arm portion 31A comes from the minimum diameter portion 86d of the cam groove 86 to the large diameter portion 86B, the first link member 31 is moved to the position shown in FIG.
In, the counterclockwise rotation (clockwise in FIG. 2) is performed. With the first link member 31, the second link
The link member 32 rotates, and the slider 150 returns to the home position.

When the slider 150 returns to the home position, the check claw 141 of the check claw plate 140 attached to the guide plate portion 130 of the apparatus body 11 prevents the holding plate 101 from returning together with the slider 150. To be done.

On the other hand, the cam 90 rotates together with the drive cam 85. Since the small diameter portion R1 of the cam 90 and the portion 86C (see FIG. 9) of the cam groove 86 of the drive cam 85 correspond to each other, the slider When the 150 moves back and forth, the cam 9
Since the shaft 62 is in contact with the small diameter portion R1 of 0, the clamp members 51 and 52 remain in the state shown in FIG.

Then, the drive cam 85 further rotates so that the tip portion 31b of the arm portion 31A is moved to the large diameter portion 86 of the cam groove 86.
When B is moved and the shaft 62 comes into contact with the peripheral surface of the increasing portion R2 of the cam 90, the clamp rotating member 53 rotates counterclockwise (in FIG. 12) about the shaft 63 as a fulcrum. . With this rotation, the clamp members 51, 52 rotate in the closing direction, and by this rotation, the sandwiching plate 101 'is pushed forward and bent into a dogleg shape.

When the drive cam 85 further rotates and the shaft 62 of the clamp rotating member 53 reaches the peripheral surface of the large-diameter portion R3 of the drive cam 90, the clamp portions 73 and 77 are further closed. As described above, the sandwiching plate 101 'is bent, and the bent portion 101a is crimped by the clamp members 51 and 52, so that the sheet bundle S is bound by the sandwiching plate 101'.

When the drive 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 drive cam 90, the clamp rotating member 53 uses the shaft 63 as a fulcrum. The clamp members 51, 52
Rotates in the opposite direction to the above. The shaft 62 of the clamp rotating member 53 is connected to the small diameter portion R1 of the drive cam 90.
12 is reached, that is, when the drive cam 85 and the cam 90 make one rotation, the clamp members 51 and 52 are moved to the position shown in FIG.
Return to the home position shown in and switch M2
Detects the concave portion 90A of the cam 90 and the drive of the drive motor 81 is stopped.

[0071]

As described above, according to the present invention, the binding member can be reliably sent to the binding position regardless of the size of the gap between the binding members.
Moreover, even if the forward movement of the sending means is stopped during the forward movement of the link driving means, the link driving means is prevented from being locked.
