DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, there has been known a clipping machine which clips a plurality of sheet members (sheet bundle) with a clip member (clip plate) (see Japanese Utility Model Publication No. 47-12089).

FIG. 53 and FIG. 54 show such a clipping machine.
As shown in FIG. 1, a handle 2 rotatably provided at one end of a base 1 and a cover 3 provided between the base 1 and the handle 2 are provided. A guide groove 4 is formed on the upper surface of the base 1. A connection clip plate 5 is housed between the guide groove 4 and the cover 3. This connecting clip plate 5 is a clip plate 5N.
Are connected with an adhesive like a stapler needle,
Each clip plate 5N has an upper end slightly curved upwards U
It is bent in a letter shape.

The other end (rear end) of the connecting clip plate 5
Is in contact with a metal fitting 7 slidably provided on the push rod 6 shown in FIG. 55. The metal fitting 7 attaches the connecting clip plate 5 to the left (in FIG. 54) by a spring 9 provided on the push rod 6. I'm going. Due to this bias, one end side (tip portion) of the connecting clip plate 5 is in contact with one end 4 </ b> A of the groove 4.

A push plate 8 is provided on the lower surface of the handle 2. When the handle 2 is rotated from the solid line position in FIG. The clip 5N comes into contact with the bent base 5Na of the plate 5N and is separated from the connecting clip 5. Then, only the separated clip plate 5N is further compressed and deformed by the pressing of the push plate 8, and the end of the sheet bundle inserted from the direction of arrow P to the bent base 5Na is clipped by the clip plate 5N. .

[0006]

By the way, in the conventional clipping machine, it is necessary to increase the width of the clip member 5N to make it plate-shaped in order to make the clip by the clip member 5N more reliable. However, if the width is increased, the number of sheets that can accommodate the clip members 5N is reduced, and the connecting clip plate 5 must be replenished frequently, which is very inconvenient.

Further, since the sheet bundle is inserted into the clip member 5N and the bent base portion 5Na of the clip member 5N is crushed to clamp the sheet bundle, when the sheet bundle becomes thicker, the bent base portion 5Na is sufficiently inserted. It cannot be crushed, so that there is a problem that a sufficient clipping force cannot be obtained.

In order to accommodate a large number of clip plates, a plate-like clip plate is stored in a cartridge, and the clip plate is extracted from the cartridge. A clip device that bends in a U-shape and then slightly crushes the rear part from above so that only the leading end closes, and then clips the sheet bundle by holding the clip plate in the sheet bundle while opening the leading end is considered. Can be According to such a clip device, since the leading end portion is opened and the clip plate is sandwiched between the sheet bundle, a sufficient clipping force can be obtained even if the sheet bundle is thick.

However, in such a clip device, since the rear portion of the clip plate is crushed so that the front end portion closes, if the sheet bundle is removed from the clipped clip plate, the front end portion of the clip plate is closed. For this reason, there is a problem that it is difficult to insert another sheet bundle into the clip plate, and it is difficult to reuse the sheet bundle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a clip device which can easily insert a sheet bundle when a clip plate is reused.

[0011]

In order to achieve the above object, according to the present invention, there is provided a clip plate having a substantially flat plate-like shape in which both ends are closed and a rear portion is expanded. A clip device that folds the sheet bundle into two folds, then opens both end portions thereof, inserts a sheet bundle into the two-folded clip plate, and clips the sheet bundle. It is characterized in that it is warped in the opposite direction.

According to a second aspect of the present invention, a substantially flat clip plate is folded into two folds such that both end portions are closed and a rear portion is expanded by movement of a forming body. A clip device for opening a portion, inserting a sheet bundle into the two-fold clip plate, and clipping the sheet bundle, wherein one end of the clip plate is connected to the clip plate when the forming body is moved. An end bending means for warping in a direction opposite to the bending direction is provided.

According to a third aspect of the present invention, the end bending means includes an abutting portion that abuts one end of the clip plate. The one end portion may be bent in a direction opposite to a bending direction of the clip plate.

During this period, the distal end portion 31b of the arm portion 31A of the first link member 31 is connected to the second large diameter portion 1 of the cam groove 183.
After entering the maximum diameter portion 183E through 83D, the slider 130 returns to the home position.

That is, when the slider 130 returns to the home position, the forming body 70 is slightly advanced, so that the forming body 70 is prevented from pressing the anvil portion 161 and the slider 130 reliably returns to the home position. Can be done.

By the way, when the shaft 65 of the drive link 61 slides on the circumferential surface of the large diameter portion R3 of the cam body 190, FIG.
The drive link 61 rotates counterclockwise from the state shown in FIG. 40 to the state shown in FIG. 40, and the forming body 70 further moves forward. When the forming body 70 moves forward from the position shown in FIG. 39, the inclined surface 73a of the pressure plate 73 is in contact with the roller 87 of the tip bending guide member 85, so that as shown in FIG. The pressing plate 73 rotates counterclockwise about the shaft 73J as the forming body 70 advances, and the pressing portion 80 of the pressing plate 73 descends while moving forward.

Therefore, the inclined surface 80A and the protruding portion 80B of the pressurizing portion 80 crush while pushing the rear portion 231h of the clip plate 231 forward. As a result,
The lower end portion 231b of the lower portion 231B of the clip plate 231 is connected to the bottom surface 75 of the notch 75 of the forming plates 71 and 72.
