DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staple feeding mechanism in a roll staple cartridge capable of appropriately feeding out a rolled staple wound in a roll shape when an abnormality occurs.

[0002]

2. Description of the Related Art In general, an electric stapler uses roll staples formed by connecting straight staples and winding them in a roll shape so that as many staples as possible can be continuously punched out. Is known in which the staples are sequentially formed into a U-shape from a staple and then punched out. The roll staple is attached to the cartridge and attached to the stapler main body, and the staples sent out from the staple feed passage of the cartridge are formed into a U-shape by molding means, and the formed staple is directed toward the material to be sewn by the driver. It is configured to be launched.

[0003] When a formed staple is driven toward a material to be sewn, a driving failure may occur and the staple may not be driven out and may be jammed in the cartridge. In this case, the jammed staples must be removed. Since it is necessary to send the roll staples slightly out of the cartridge, the staples are sent out of the feed passage by pushing a ratchet plate protruding from the end of the cartridge. Further, when the roll staple is stored in the cartridge for the first time, it is necessary to feed the leading end from the entrance to the exit of the feed passage. At this time, the cartridge was first loaded in the stapler body, and then the staples were moved along the feed path by performing an idle driving operation.

[0004]

However, in the former, the face plate must be opened and the ratchet plate must be pressed directly. Also, after the ratchet plate is pushed in, it is fed by the same amount as the pushing amount, so it is not possible to adjust the feeding amount at the time of pushing in, the staples will be out too much, and the work must be done because the staples that have come out too much must be cut off Was. In the latter case, the user must perform the blanking many times, which is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a staple feeding mechanism in a roll staple cartridge which can solve the above-mentioned drawbacks and can easily feed roll staples in a feeding path.

[0006]

In order to solve the above problems, a staple feeding mechanism in a roll staple cartridge according to the present invention accommodates a roll staple formed by connecting straight staples and winding the same in a roll shape. In a roll staple cartridge provided with a storage section to be inserted and a staple feed path continuous from an opening formed in the storage section, the roll staple in the staple feed path is engaged with the upper or lower side of the staple feed path. A feeding means having a feeding claw to be fed and a feeding lever exposed to the outside is provided so as to be manually movable in the staple feeding direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 3, reference numeral 1 denotes a roll staple cartridge. This roll staple cartridge has a cartridge body 1a provided with a storage section 3 for roll staples 2 and a staple feed passage 4. Roll staple 2 in staple storage unit 3
Is stored. The roll staple 2 is formed by connecting straight staples with an adhesive tape and winding them in a roll shape.

The lower part of the storage part 3 is opened, and this opening 5
The outermost end of the roll staple 2 is led out of the staple feed passage 4 so as to pass therethrough. Further, a cap 5 is attached to an upper portion of the storage section 3, and the roll staple 2 is configured such that the cap 5 can be opened and stored in the storage section 3.

The staple feed passage 4 is continuous with the opening 6 of the storage section 3 and is formed between the upper guide plate 7 and the lower guide plate 8. The claw 9 is disposed to be inclined forward, so that the staple 2 that has moved forward of the feed passage 4 does not move backward. The rear part of the lower guide plate 8 is open. A feed plate 11 is arranged on the lower surface side of the lower guide plate 8 so as to be able to move back and forth. As shown in detail in FIG.
Three feed claws 10 are fixed to the upper surface of the feed plate 11 so as to be inclined forward, and the feed claws 10 project from the open portion of the lower guide plate 8 into the staple feed passage 4. The feed lever 12 is formed so as to be exposed downward from the lower surface of the feed plate 11. This feed lever 12 is used for the cartridge body 1.
a protrudes outside through an opening hole 13 formed in the lower part of a. The feed lever 12 is formed so as to be able to move inside the opening hole 13, and this movement is the movement range of the feed plate 11.

In the above configuration, as shown in FIG.
After introducing the tip of the roll staple 2 stored in the feed passage 4 into the inside of the feed passage 4 from the opening 6 and moving the feed plate 11 forward and backward with the feed lever 12, the feed staple 2 was moved forward as shown in FIG. Since the feed claw 10 of the feed plate 11 sometimes engages with the roll staple 2, the roll staple 2 is fed out by the movement of the feed plate 11. When the roll staple 2 is moved backward, the roll staple 2 cannot move backward because the check pawl 9 is engaged with the roll staple 2. In this way, the roll staple 2 can be fed by the movement of the feed lever 12.

A face plate (not shown) is arranged at the front end of the feed passage 4. On the back surface of the face plate, formed staple driving grooves are formed in the vertical direction, and staple needles drawn out of the feed passage 4 and formed into a U-shape by a forming means (not shown) are driven. When a staple jammed in the above-mentioned driving groove is to be processed when a driving failure occurs, the face plate is opened to remove a jam needle, the face plate is closed, and the roll staple 2 is moved together with the feed plate 11 by the feed lever 12. Just send it forward.

Reference numeral 18 denotes a ratchet plate. The ratchet plate 18 is fixed to the feed plate 11 and is urged forward by a compression spring 15. When the machine is operating, it is moved to move the feed plate 11 back and forth to feed the needle.

As described above, since the feed amount of the roll staple 2 is the same as the feed amount of the feed plate 11, it can be appropriately adjusted from the outside. In addition, since the feed of the feed plate 11 can be performed by the feed lever 12 protruding to the outside, the operation is simple.

The feeding means does not need to be formed in a plate shape as in the above-described feeding plate 11. Further, it may be provided on the upper surface side of the staple feed passage 4.
