[0002]

2. Description of the Related Art Conventionally, there is known a clip machine for clipping the ends of a plurality of sheet members with a clip member (see Japanese Utility Model Publication No. 47-12089).

Such a clip machine is shown in FIGS. 76 and 77.
As shown in FIG. 1, a handle 2 rotatably provided at one end of the base 1 and a cover 3 provided between the base 1 and the handle 2 are provided, and a guide groove 4 is formed on the upper surface of the base 1. A connecting clip member 5 is housed between the guide groove 4 and the cover 3. The connection clip member 5 is formed by connecting clip members 5N with an adhesive like a stapler, and each clip member 5N is bent in a U shape.

The other end (rear end) of the connecting clip member 5
78 is in contact with a metal fitting 7 slidably provided on the push rod 6 shown in FIG. 78. This metal fitting 7 attaches the connecting clip member 5 to the left (in FIG. 77) by a spring 9 provided on the push rod 6. I am energetic. Due to this biasing, one end side (tip portion) of the connecting clip member 5 is in contact with one end 4A of the groove 4.

A push plate 8 is provided on the lower surface of the handle 2, and when the handle 2 is rotated from the solid line position in FIG. 76 to the chain line position, the push plate 8 moves toward the clip member 5N at the tip of the connecting clip member 5. The clip member 5N is separated from the connecting clip member 5 by abutting on the bent base portion. Then, only the separated clip member 5N is further compressed and deformed by the pressing of the pressing plate 8, and the end portion of the sheet bundle inserted in the arrow P direction is clipped by the clip member 5N.

[0006]

By the way, in order to make the clip by the clip member 5N more reliable, it is necessary to widen the width of the clip member 5N to make it into a plate shape. There is a problem in that the number of clip members 5N that can be stored is reduced and the connecting clip members 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 sandwich the sheet bundle, when the sheet bundle becomes thick, the bent base portion 5Na is sufficiently It cannot be crushed, and as a result, it cannot get enough clipping force,
There is a problem that the sheet bundle easily comes off from the clip member 5N.

The present invention has been made in view of the above problems, and an object thereof is to obtain a sufficient clip force regardless of the thickness of a sheet bundle and to accommodate a large number of plate-like clip plates. The object is to provide a clip device that can do this.

Another object of the present invention is to provide a clip device which is capable of bending a clip plate so that the tip does not open even if the clip plate is made of an elastic member. Especially.

[0010]

In order to achieve the above-mentioned object, the present invention provides a clip plate having a substantially flat plate shape in which the front end portion is closed and the rear end portion is inflated. It is characterized in that the sheet bundle is folded in three and then the tip portion is opened and the sheet bundle is inserted into the two-fold clip plate to clip the sheet bundle.

According to a second aspect of the present invention, a cartridge containing a plurality of substantially flat plate-shaped clip plates, a feeding means for feeding the clip plates from the cartridge to a predetermined position, and a clip plate fed to the predetermined position are provided at the front end. Bending means for folding into two folds with only the part closed and the rear part inflated, and the tip of the clip plate folded in two is opened, and the sheet bundle is inserted into this opened tip. And a clip means for clipping the sheet bundle.

By the way, since the clip plate 231 on which the sheet bundle T is clipped is in a state where the creases are formed by the corner portions 231d and 231e, the sheet bundle T can be clipped with a strong force.

After the flat plate-shaped clip plate 231 is bent in a U shape, the tip portion 231 of the clip plate 231 is bent.
a and the front end portion 231b are closed, and the rear portion is folded in two in a bulged state.
Since the sheet bundle T is clipped by opening the sheets 1a and 231b and inserting the sheet bundle T into the clip plate 231, the sheet bundle T can be clipped with a clipping force of a predetermined value or more regardless of the thickness of the sheet bundle T.

In this embodiment, the flat clip plate 231 housed in the cartridge 200 is attached to the slider 1
The sheet bundle T is sent out to a predetermined position by 30 and the sent out clip plate 231 is bent in a U shape by the forming body 70 or the like to clip the sheet bundle T. Therefore, the cartridge 200 has a flat plate shape. It suffices to store the clip plates 231. Therefore, the number of clip plates 231 to be stored in the cartridge 200 can be increased. In addition, in this embodiment, the plurality of clip plates 231 are bonded to the tape 240 in the form of a band and connected to each other, and the tape is wound into a roll.
Since it is housed in 0, the number can be further increased, and it is not necessary to frequently refill the cartridge 200 with the clip plate.

The clip plate 231 clipped on the sheet bundle T has a tip portion 231a as shown in FIG. 73 (B).
Is bent, the clip plate 231 can be easily removed from the sheet bundle T by putting a finger on the tip portion 231a, and the clip plate 231 can be used again as a clip. When used again, the tip 231b and the tip 231a of the clip plate 231 are
The sheet bundle can be clipped by inserting the sheet bundle between and, and the clip plate 231 can be used any number of times. Further, since the tip portion 231a of the clip plate 231 is bent, the tip portion 231b and the tip portion 231a are
A sheet bundle can be easily inserted between and.

In this embodiment, the clip device 231 which bends the clip plate 231 to clip the sheet bundle T has been described. However, as shown in FIGS. 59 and 60, the clip plate 231 is bent and the bent clip plate 2 is bent.
It can also be used as a clip manufacturing device for manufacturing 31. That is, unless the sheet bundle T is placed on the sheet tables 310 and 320, the clip plate 231 bent as shown in FIGS. 59 and 60 is manufactured, and the clip plate 231 is formed as described above. You can use it.

By the way, when the slider 130 is at the home position (the position shown in FIGS. 25 and 26), the inclined plate portion 154 of the feeding claw plate 150 has the housing 1
By not contacting the protrusions 23B, 23B of the front wall 22 of No. 2, the tip portions 153a, 15 of the feeding claws 153, 153 are
Since 3a is pulled from the back surface of the anvil plate 160 to the front side, when the cartridge 200 is removed, the clip plate 231 in the transport path 211 of the cartridge 200 is removed.
It is possible to prevent a problem that the tip portions 153a and 153a of the feeding claws 153 and 153 are caught and the clip plate 231 is pulled out from the cartridge 200.
