Description

[Detailed description of the invention] (Field of application of the invention) This invention relates to a staple cartridge for a stapler.

(Prior art and its problems) A stapler of the type in which a large number of wire-like unformed staples are adhesively connected in a sheet form (hereinafter simply referred to as a sheet staple) is formed into a U-shape and punched out. A staple cartridge is used in which a large number of sheet staples are stacked and stored. However, with such staple cartridges, the sheet staples rise and fall inside the cartridge body due to the vibrations and shocks that occur during transportation and transportation, causing the upper and lower sheet staples to collide with each other, causing some of the sheet staples to break down. The sheet staples may be separated and stacked one on top of the other, or the posture may be distorted, resulting in disordered alignment, which may result in poor ejection of the sheet staples from the outlet formed at the lower end of the front wall of the cartridge body. Sometimes. In order to prevent this, recently, a staple cartridge has been proposed in which the following weight 3 is disposed within the cartridge main body 1a that stores sheet staples S in a stacked manner, as shown in FIGS. 4a and 4b. ing.

This weight 3 has elastic locking claws 8, 8 on the front and back of the upper surface of the weight body 3a diagonally upward.
The cartridge main body 1a is provided in such a way that it contacts and locks the corrugated locking surfaces 7, 7 formed on the front and rear inner walls of the cartridge body 1a, and moves downward by the elasticity of the locking claws 8, 8, but upwardly. When you try to move to the locking claw 8,
8 is opened to strengthen the locking with the locking surfaces 7, 7, thereby preventing upward movement, and is placed on top of the sheet staples S, S, . . . in the cartridge main body 1a. According to this staple cartridge, the sheet staples S, S, etc. can be pressed downward at all times, so that the sheet staples cannot be moved even by vibrations, shocks, etc. during transportation, transportation, etc. The consistency can be maintained well.

However, when the weight 3 is configured to be able to move only downward, although the alignment of the sheet staples S, S, etc. is maintained, the sheet staples are pressed against each other and become jammed. Therefore, from the outlet 5 to the lowest sheet staple S
It becomes difficult to derive the sheet staple, which may result in poor feeding of the sheet staple.

In addition, in the staple cartridge described above, the sheet staples S may fly out from the outlet 5 of the cartridge main body 1a due to vibrations or shocks during transport or transportation. Since S cannot be stored in the staple cartridge again and is wasted, a solution to this problem has also been desired.

(Technical issues of the invention) This invention solves the above problems, maintains the integrity of the sheet staples inside the cartridge body well, and prevents the internal sheet staples from popping out during transportation, transportation, etc. The technical object of the present invention is to propose a stapler cartridge for a stapler that also allows sheet staples to be fed out from the outlet port.

(Means for Solving the Problems) In order to solve the above problems, the staple cartridge for staplers according to this invention is a multi-stage stack of sheet staples made by adhesively connecting a large number of unformed wire-like staples into a sheet. a storage section for storing the staples, and a lower end of the front wall of the storage section is provided with an outlet for the lowermost storage sheet staple;
In the stapler cartridge cartridge, a staple pressing material is arranged on the lowermost sheet staple to allow the stored sheet staple to move to the outlet and prevent it from moving to the opposite side. A plate that can be extracted from the outlet and has a thickness substantially the same as the height of the outlet is disposed in the lower stage, and the sheet staples are stacked and stored on the plate.

(Operations and Effects of the Invention) As described above, according to the staple cartridge for staplers according to the invention, the conventional sheet staple alignment is maintained by the weight, and when the plate is used, the plate is connected to the outlet of the cartridge body. By pulling it out, a space corresponding to the thickness of the plate will be created in the sheet staple storage section.
The jammed state between sheet staples is eliminated. Therefore, it is possible to smoothly staple the sheet from the exit port.
can be reliably derived.

In addition, by placing a plate at the bottom of the sheet staples in the cartridge body, the lowest sheet staple cannot go down to the position opposite the outlet, and the outlet is blocked by the plate, making transportation easier. Even if there is considerable vibration or shock during transportation, the sheet staple will not fly out from the outlet.

Therefore, the practical effect is very large.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 indicates a staple cartridge for a stapler. This staple cartridge 1 stores sheet staples S stacked in multiple stages in a cartridge main body 1a, and a plate 2 that can be pulled out to the outside is arranged at the bottom of the sheet staples S, and a weight 3 is installed at the top of the sheet staples S. This is what was posted.

The cartridge main body 1a has a storage section 4 for sheet staples S, and guide sections 4a, 4a are protrudingly provided in front of the front wall of the storage section 4, and the sheet staples S at the lowest stage are sequentially led out from the lower end of the front wall. The bottom of the storage section 4 is open except for the staple support sections 6, 6 on both sides. Further, corrugated locking surfaces 7, 7 are formed on the front and rear inner wall surfaces of the cartridge main body 1a, respectively. The staple cartridge 1 is mounted on an endless belt 10 provided in a magazine, and due to the contact friction between the endless belt 10 and the lowermost sheet staple S exposed from the open bottom part of the cartridge body 1a, When the endless belt 10 moves, the lowermost sheet staple S also moves, and the outlet 5
and is transferred to a predetermined position in the magazine. Therefore, in normal cases, the height of the outlet is set to a size equivalent to about one and a half to two sheet staples. The reason for this is that the sheet staple S in the lowest row comes into contact with the endless belt and floats a little, so if there is not enough room in the outlet 5, the sheet staple S
This is because it is not possible to derive it smoothly.

The weight 3, like the conventional one, has elastic locking claws 8, 8 on the front and rear of the upper surface of the weight body 3a.
It projects obliquely upward, and is configured to be movable only downward within the cartridge body 1a by being engaged with the locking surfaces 7, 7 of the cartridge body 1a.

The plate 2 is made of a plate-like material such as metal or synthetic resin, and its length l is approximately the same as the length from the tip of the guide part 4a to the rear end of the storage part 4, and its thickness t is the same as that of the cartridge body 1a. It can be extracted from the outlet 5 and is formed to have approximately the same height as the outlet 5. The width of the front part w1 is approximately the same as that of the cartridge body 1a, and the rear part w2 is approximately the same as that of the sheet staple S. It is formed at a position corresponding to the front end of the staple support parts 6, 6. The plate 2 is inserted into the cartridge main body 1a before the staple cartridge is used, and is pulled out and removed when the staple cartridge is used.

Note that the dimensions of the plate 2 are not necessarily limited to those of the above embodiment except for the thickness t.

The staple cartridge 1 first inserts the plate 2 into the cartridge main body 1a through the outlet 5, and then stores the sheet staples S thereon by stacking them from the upper opening of the cartridge main body 1a.
Furthermore, it is constructed by placing a weight 3 thereon. When transporting, a large number of staple cartridges 1 having the above configuration are packed in a packaging box (not shown) and transported in this state.
be transported.

Therefore, in the staple cartridge 1, firstly, the integrity of the sheet staples S, S, etc. in the storage section is maintained by the weight function of the weight 3, and when the staple cartridge 1 is used, the plate 2 is inserted into the outlet 5 of the cartridge main body 1a. By pulling out the sheet staples, a space corresponding to the thickness t of the plate 2 is created in the sheet staple storage section 4, so that the jammed state between the sheet staples S, S, etc. is eliminated, and the upper and lower sheet staples S,
There is some margin between S. Therefore, the sheet staple S can be smoothly and reliably led out from the outlet 5.

Furthermore, by disposing the plate 2 below the sheet staples S of the cartridge body 1a, the sheet staples S at the lowest stage cannot descend to a position opposite to the outlet 5, and the outlet 5 is blocked by the plate 2. Since it is peeled off, the sheet staple S will not fly out from the outlet 5 even if there is considerable vibration or shock during transportation. Moreover, the length of the plate 2 is approximately 1 of the cartridge body.
Because it is formed to be approximately the same length as the front and back of a,
The plate 2 will not fall out from the stapler main body 1a within the packaging box during transportation or the like.
