Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a metal staple (also called a needle or foot).
The present invention relates to a method of binding paper sheets such as documents using a stapler, and a stapler that is a stationery for carrying out the method.

(Prior Art) A stapler and a paper binding method using a stapler are known in the art, in which 30 or 50 gate-shaped staples with a small rectangular cross section are bonded together with an adhesive to form a staple assembly. This aggregate is housed in the staple accommodating part of the stapler, and the staples in the aggregate are fed through the accommodating part by a coil spring so that they sequentially reach the gap on the lower surface of the tip of the accommodating part, and are placed above the accommodating part and the substrate. A pushing member that corresponds to and can be inserted into the gap at the tip of the accommodating part is provided at the tip of the cover part whose one end is pivotally supported, and the cover part and the accommodating part are rotated around the support shaft by the gum of the base part. By moving the staple, the pushing member of the cover part pushes down one staple located above the gap of the storage part, and the descending staple passes through the plurality of sheets of paper placed on the pushing base at the tip of the base part, and is further pushed down. The paper is bound by pressing both ends inward on the base.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, a large number of staples bent into an n-shape are connected and bonded to each other using an adhesive to form a - unit staple assembly (30 staples, 50 staples, etc.). ), which is housed in a stapler and used as a binding tool. However, manufacturing such a staple assembly requires at least three steps: bending the staples, assembling them in an aligned state, and connecting and bonding them with an adhesive or the like. Because of this, it is difficult to uniformly apply and adhere the adhesive, and the assembly has the disadvantage that it splits before use (before being placed in a stapler).

Also, the number of staples that can be stored in the storage section at one time is
Normally, the number is one staple set, or 50 staples, and once this is used, the cover must be opened, the pusher pushed back, or the pusher removed to load a new staple set. When binding a large number of document sets, it is troublesome to have to stop the work many times and replenish the staple assembly. Furthermore, if the staple assembly had weak adhesive strength, the assembly would often split during loading due to hurried handling, resulting in wastage.

(Objective of the Invention) The present invention eliminates the drawbacks of the prior art as described above, uses staple materials in the unfolded shape without pre-bending the staples, and allows the stacking of multiple staple materials to be applied from above. An object of the present invention is to provide a method for feeding paper from the bottom and then from the rear to the front to a working position (stapling position), bending it during the feeding, and binding the paper as a ■-shaped staple, and a stapler for carrying out the method. shall be.

Further, as a staple material, a flat staple material aggregate consisting of a plurality of the above-mentioned staple materials is used,
By using a plurality of staples in a stacked state, the purpose is to reduce work interruptions and the complexity of replenishing staples.

It also aims to make it easier to use die-cut needles, which have recently started to be used.

(Structure of the Invention) In order to achieve the above object, the paper binding method of the first invention of the present application includes a step of arranging a plurality of unbent staple materials in a stacked state at a standby position, feeding the lowest staple material to a feeding position; feeding the staple materials at the feeding position sequentially through a bending position to a working position; bending the staple material into staples by applying a downward force to certain lengths on both sides of the staple material, and applying a downward force to one bent staple that has reached the working position to It is characterized by including a step of binding.

On the lower surface of the front end of the feeding passage section B, there is a lateral gap 9 through which the bent staple passes, at a position facing the pressing member 3 of the pressing handle section 2, and a bending means 10 at a position facing the bending member 4. is established.

At the rear thereof, a feeding means 1 for feeding the staple material aggregate 8 supplied from the storage section 7 of the cover section A forward.
1 is provided.

On the upper surface of the front end of the substrate section C, there is a pressing pedestal 12 at a position facing the front end of the feeding passage section B, and a recess 13 is provided opposite the gap 9.

The recessed member 5 has a central recess 14 with a width equal to the width of one bent staple, and a peripheral outer side 15 extending downward from the central recess 14.
on the lower surface, the thickness of which is equal to the thickness of at least one (one in this embodiment) staple material 8' in the front-rear direction. The front shape of the bent member 5 is preferably a convex shape with both shoulder corners dropped, as shown in FIG.

Bending means 10 cooperates with this bending member 5 to bend the staple material 8' to shape the bottom of the medium-sized stable 8'.
The supporting table 16 has a width equal to the bent staple width, and the stopper 1 is provided on the outside of the support table 16 in a direction perpendicular to and parallel to the surface of the staple material aggregate 8 being fed.
7 and a bending guide plate 18. The upper end of the stopper 17 provided at the front is equal to or higher than the surface height of the staple material assembly 8, and the upper end of the stopper 17 provided at the front is higher than or equal to the surface height of the staple material assembly 8.
The upper end of the staple material assembly 8 is equal to or lower than the height of the back surface of the staple material assembly 8.

In this embodiment, the feeding means 11 of the feeding passage B passes from the accommodating part 7 of the cover part A through the lower end opening of the feeding passage B.
A pusher 19 and a coil spring 20 that feed the staple material assembly 8 supplied to the front.

It is composed of a guide member 21 that supports the fed staple material assembly from below so that it always maintains a correct and stable posture, and a rear pressing member 6 that presses the staple material assembly onto the guide member 21 from above. In this embodiment, the guide member 21 has a coil spring 2 along the longitudinal midline of its lower surface.
A long platform with a rectangular cross section is formed with a guide groove for 0, and in front of the bending guide plate 18 is the support platform 16 described above.
It reaches just before gap 9. Sl,S
2, Sl and S are each a coil spring or a leaf spring.

Next, the use of the stapler of this embodiment will be explained.

First, the plurality of staple material aggregates 8 described above are properly accommodated in the accommodating section 7 of the cover section A. In this embodiment, for example, a cartridge 22 containing 20 stacked flat staple material aggregates 8 each consisting of 50 staple materials (1000 staple materials) is opened and turned upside down. It is housed in the housing section 7. The staple material assembly 8 in the cartridge 22 is
The pusher 19 under the lower end opening of the housing section 7 is supported by the spring S4.
Since the pusher 1 is pressed upward, a pusher operating tool (not shown) protruding from the side surface of the feeding passage means B
9 is moved backward in the direction of the arrow against the coil spring 20.

When the staple material assembly 8 is positioned behind the rear end, the staple material assembly 8 is placed on the guide member 21 and is fed forward by the pusher 19 and the coil spring 20, and the length of the staple material assembly 8 in the front-rear direction is The front end contacts the stopper 17. This staple material assembly 8 is supported by the guide member 21 from below, and pressed from above by the rear pressing member 6 by the spring S, and is stably held between them. When the pressing handle part 2 is pressed down, the front end of the feeding passage first contacts the pressing pedestal 12 against the spring S, and then when pressed down further against the spring S8, it contacts the stopper 17. The bending member 5 descends onto the frontmost staple 8'.

The tips of one of the outer sides 15 of the bending member 5 abutted against both ends of the staple material 8' and pressed it downward, so that the central recess 14 of the bending member 5 reached the upper surface of the staple material 8'. At this time, the staple material 8' is formed into a ■-shaped staple 8' having the same shape as the front cross section of the support base 16.

During this bending process, the circumferential outer part of the staple material 8' being bent and the surface outer part 15 of the bending member 5
is inserted into the gap between the stopper 17 and the bending guide plate 18, so that the staple material 8' is processed into the correct square shape. At this time, the pressing member 3 also descends, and its tip reaches the recess 13 of the pressing base 12.

The bent staple 8' is no longer the stopper 1.
7, the support stand 16 and the stopper 17
It is fed forward through the gap between the By repeating this several times, the staple material 8' that comes into contact with the stopper 17 is sequentially bent into a staple 8', which is sent toward the gap 9. Of course, the adhesion on the upper surface of each staple 8' is still maintained. During this time, the assembly of staples 8' connected at the upper surface is correctly and stably held between the front pressing member 4 and the support base 16 by the spring S2.

In this way, when the foremost staple 8' reaches the gap 9,
When the pressing handle portion 2 is pressed down next time, the staple 8' is pressed down through the gap 9 by the pressing member 3.
It is bent in the recess 13 of the press pedestal 12, and documents on the press pedestal 12 are bound.

Generally, the pusher 19 moves one staple material assembly 8 to the position of the stopper 17 or the bending guide plate 18, although this varies depending on the length of the staple material assembly 8 in the front-rear direction and the distance between the front end of the accommodating portion 7 and the stopper 17. When the pusher 19 reaches that point, push it back in the direction of the arrow with the operating tool to feed the next staple material aggregate 8.
is supplied from the storage section 7 to the feeding passage B, and the same procedure is repeated until the staple material aggregate 8 stored in the storage section 7 (in this embodiment, the cartridge 22) is used up. There isn't.

Instead of accommodating the plurality of staple material aggregates 8 in the cartridge 22, it is also possible to directly accommodate them in the accommodating portion 7 and cover the back surface with a lid equipped with a push spring. Also, the thickness stopper 17 of the bent member 5. If the gap between the guide plates 18 is made equal to the thickness of several staple materials 8', several staple materials 8' can be bent by one depression operation of the pressing handle portion 2.

In the illustrated embodiment, the feeding passage section B is attached to the lower side of the cover section A, and only the pressing handle section 2 moves up and down relative to the feeding passage section B, but this is different from the conventional stapler. Similarly, the feeding passage section B is pivotally supported on the cover section A or the substrate section C, or both, and a spring is inserted between the rear ends of the cover section A and the feeding passage section B in place of the pressing handle section 2. By rotating the cover part A around the axis so as to press it against the feeding passage part B against the It is also possible to adopt a configuration in which bending and binding operations are performed in addition to pressing.

In the above description, a case has been described in which a number of plate-shaped staple material aggregates 8 are stacked and stored in the storage portion 7 of the cover part A, but a single staple material 8' that has not been bent is
It is also possible to carry out a modification in which a number of books are stacked one above the other (conveniently stored in the cartridge 22). In the case of this modification, although it is not possible to accommodate a large number of staple materials at once into the stapler (inside the storage section 7) as in the illustrated embodiment, the stapler is very small (especially A stapler with short longitudinal dimensions can be obtained.

This modification is also effective as a stapler that uses die-cut staples that have recently been commercially available.

In other words, a die-cut staple is a staple with an arbitrary shape, such as a circle or a heart shape, protruding from one side of the top surface of the staple, and is intended to give an aesthetic sense when binding documents. However, because of this overhang, it is not possible to line up the staples and glue them one after the other like with conventional staples, so the staple assembly is made by aligning the legs on both sides, stacking the top and overhang in a stair-like manner, and gluing only the sides. (For example, 25
I am using it as a book). For this reason, the staple assembly accommodating portion of the stapler also has a special shape, the stapler must be large in proportion to the number of staples, and the adhesion between the staples is also very weak.

However, if the above-mentioned modification is used, neither bending nor adhesion is necessary, and the staple materials that have just been cut out can be stacked and accommodated in the storage section.

Since projecting portions on the upper surface of the staple can be provided on both sides, which was not possible until now, the use of die-cut staples can be expanded.

(Effects of the Invention) As explained in detail above, the paper binding method of the present invention and the stapler that implements the same have the following effects.

■ The staple material is easy to manufacture because it uses a staple material that does not undergo bending and is bent into staples immediately before binding.

(2) Since the staple materials are loaded into the storage section in a stacked state without being glued together, the production of staples becomes easier.

■ If you use a flat staple material aggregate (usually connected and bonded with adhesive), 1
The number of staple materials that can be loaded into the storage section at one time can be significantly increased compared to conventional staplers.

■ Very convenient for using die-cut needles.
