The present invention relates to a Ho-chi-gi-chi, that is, a paper iron machine, for ironing laminated paper.

More specifically, the present invention relates to a device for preventing injury of multiple long needles in a paper-making machine, which is able to hold a plurality of iron needles unitized in a frame as an extremely simple structure.

자의 형을 한 철침을 내장하고 있다. 철침은 소정 개수(통상의 규격이 50개)을 풀로 부착하여 유닛트화 하고, 이 유닛트화한 유닛트 철침을 지철기에 다연식으로 장진하고 있다.Paper iron machine and nickname Hochigisu, which is a mechanism for combining various stacked documents together, have been proposed in various forms. This iron is

It has a built-in iron needle. The needle is attached to a predetermined number (normally 50 pieces) by a unit, and unitized.

Since the number of the unit needles is limited, it is also known that the unit needles are connected to the unit needle needles in a multiple manner.

Conventionally, in the paper-making machine which is equipped with a plurality of unit stitches, the unit stitches are connected to the frame and pressed from the rear, and the unit contact needles and the portions in contact with the unit stitches overlap, and they float out of the frame.

In order to prevent this rise, a needle cover was installed between the handle and the frame having the needle bar. For example, in order to prevent the above rise of the unit needle on the frame, the upper surface of which is open, such as the "needle cover device in the stapler" of Japanese Utility Model Publication No. 48-19653. The needle cover is attached to the upper surface of the needle in the frame.

Further, in order to improve the fitting between the piercing cover and the frame, protrusion pieces are provided on both side walls of the piercing cover, and container and inclined surface portions are provided on both side walls of the frame so as to fit with the piercing cover. By fitting the stone piece and the locking device to press the iron needle, it is possible to prevent the overlap and rise of the joint of the unit iron needle.

As described above, any branching machine which connects and protrudes a plurality of unit needles is provided with a needle cover device in order to prevent rising of any needle.

As described above, the conventional paper iron machine which connects a plurality of unit needles and extends them is provided with a needle cover between the frame and the handle so that the needles in the frame do not rise and protrude. When installing this iron cover, the structure of the paper-making machine becomes complicated. There was a drawback in that the air handling took place because the attachment and assembly of the iron needle cover were adjusted during manufacture of the papermaking machine.

The present invention solves the above problems of the conventional one.

An object of the present invention is to provide a device for preventing the injury of a multi-strength iron needle in a paper machine without installing the iron needle cover and not causing the iron needle to jump out of the frame.

It is another object of the present invention to provide a device for preventing the injury of multiple pinched needles in a branch machine having an extremely simple structure.

The present invention adopts the following means to solve the above problem.

A base mounted on the base and bent to stop and bend the tip of the needle, and to bend the tip of the needle, a frame having a plurality of unit needles installed therein as a rotating material on the base, and installed in the frame, to guide the movement of the needle A needle accommodating part having a support, a needle extruding part for pushing the iron needle forward from the rear in the needle accommodating part, a sliding guide for guiding a sliding operation of the extruded part installed in the frame, and rotating on the base A paper iron machine having a handle provided with material and pressing blades for pushing out the iron needle in the frame from the rear side and pushing the bending needle in the handle, wherein the needle rises in parallel with the sliding guide in the frame. To the iron, characterized in that the injury prevention portion is installed to prevent An injury prevention devices come Synchro Jangjin staple of.

In preventing the floating of the multiple long needles in the paper machine as described above, when the handle for replenishing the iron needles is opened, the immersion extrusion part in the frame connected to the handles is retracted by the tension coil spring. For this reason, a gap is created between the needle extruded portion and the floating prevention portion of the iron needle provided in the frame. When the needle is replenished in order from above the gap, and the handle is closed, the needle is pressed into the needle extruded portion and is ready for use. Since the sting loaded with multiple can guide the upper part by the injury prevention part, it does not rise.

As described above, in order to mount the paper on the base bending table and push out the handle as in the conventional paper feeding machine, the paper can be easily rolled up.

[First Embodiment]

Best Mode for Carrying Out the Invention Embodiments of the present invention will be described below with reference to the drawings.

A first embodiment of the present invention will be described with reference to FIGS.

The handle 1 has a hollow rectangular shape, and its two surfaces are open. Usually, it is made of synthetic resin material. The inside of the handle 1 is fixed by well-known means, such as the press blade 2 and the handle spring 3 being fitted. The pressing blade (2), the handle spring (3) and the metal plate are bent and made integrally.

One end of the handle 1 is provided with a conical joining hole. (Not shown). In addition, a stopper piece 4 for stopping one end of the tension coil spring 11 described later is formed on the inner upper wall of the handle 1.

The frame 5 shown in FIG. 2 has a rectangular shape (normal) in which one surface made of a metal plate is opened. The frame 5 is a multi-storage storage of the needle. In the present embodiment, the unit type iron needle 6, which has about 50 iron needles connected and bonded to the inside of the frame 5, can be quadrupled in this embodiment.

As shown in Figs. 2 and 4, the frame 5 is provided with an anti-floating part 8 for preventing the rising of the needle bar 6.

These floating prevention parts 8 and 8 are formed by cutting and bending the wall surface of the frame 5, that is, cutting and forming them. Further, on both sides of the back of the floating prevention portion 8, a plurality of floating preventing portions 8 are provided so as to protrude inward toward the inside as shown in FIG.

This floating prevention part 8 has the shape of a hemispherical surface shape, and this shape is formed by coining the process of attaching a shallow groove to the surface of the frame 5. This processing method is a well-known technique and the processing method is not described in detail.

On both sides of the rear end of the frame 5, conical joining holes 9 are provided coaxially on both sides. Engaging projections 14 are formed on both sides of the rear side of the needle extruded portion 7 so that the needle extruded portion 7 does not fall out of the frame 5. The engaging projection 14 is inserted into the sliding groove 15 provided on both side walls of the frame 5, so that the settling extrusion part 7 slides back and forth.

The needle extruded portion 7 is inserted into the frame 5 and perturbes on the sliding groove 15. As shown in FIG. 6, this immersion extrusion part 7 forms the iron immersion compression part 10 in the front part of a main body, and hangs which connects the tension coil spring 11 to the center of a back part. The protrusion 12 is provided.

One end of the tension coil spring 11 is connected to the hanging protrusion 12. The other end of the tension coil spring 11 is a hooking protrusion 4 formed on the inner side of the back of the sun 3 via a folded portion 13 (see FIG. 1) provided in the front of the handle 1. )

For this reason, the many needles 6 which always pulled out the needle-extruded part 7 toward the front and extended to the front end of the needle-extruded part 7 are pushed from behind. In order to replenish the iron needle 6, the needle extruded portion 7 is moved backward along the sliding groove 15 of the frame 5 by opening the handle 1, and the iron needle 6 at the front end thereof. ) Can be held in multiple formats.

Next, as shown in Fig. 3, the base 16 is provided with a metal bend 17 for bending the iron needle 6 on the upper surface of the front portion.

Side walls 18 and 18 are formed on both sides of the rear part of the base 16 upwardly. Conical joining shafts 19 and 19 are provided from the side walls 18 and 18 at the rear side walls 18 and 18 of the side walls 18 and 18.

The outer conical joining shaft 19 is inserted into the conical joining hole (not shown) of the handle 1, and the inner conical joining shaft 19 is inserted into the conical joining hole 9 behind the frame 5. Is fitted.

Therefore, the handle 1, the frame 5, and the base 16 can rotate, respectively.

In the figure, 20 is a base spring, 21 is a bottom plate, and 22 is a protruding portion. Hanging with a hanging protrusion (not shown) provided inside the handle 1, the handle 1 and the frame 5 is opened to a predetermined position by the elastic force of the handle spring (3). .

[Operation of First Embodiment]

Since the present invention is constituted as described above, when the handle 1 is opened to replenish the needle bar 6, the handle 1 rotates with the conical joint shaft 19 as a point. Accordingly, the traction force of the tension coil spring 11 that is pulled through the folded portion 13 between the hooking protrusion 4 in the handle 1 and the hooking protrusion 12 above the needle extruded portion 7. By this, the immersion extruded portion 7 retreats to the position indicated by the dotted line in FIG.

For this reason, the gap which is slightly longer than the length of one continuous length of the needle needle 6 is generated between the iron needle depression part 10 for diagnosing the needle extrusion part 7 and the last injury prevention part 8 provided in the frame 5. . After replenishing the four consecutive iron needles 6 sequentially from the upper part of this gap and closing the handle 1, the immersion extrusion part 7 is advanced by the contracting force of the tension coil spring 11.

This state becomes the usable state shown in FIG. 1, and the needle bar 6 has a plurality of injuries in which both shoulder portions 23 are provided inside the frame 5, as shown in FIG. 4 and FIG. The lower surface of the prevention part 8 abuts and does not rise.

As a result, when the handle 1 is placed on the bend 17 of the base 16 and pushed down on the handle 1 like the conventional paper iron machine, the pressing blade 2 is lowered, so that the piercing needle 6 in the front end of the frame 5 is lowered. This is pushed out and the paper is fed.

Then, when the pressure of the handle 1 is released, the pressing blade 2 rises as the handle 1 rises due to the elastic force of the handle spring 3. Since the protruding needle 6 is in contact with the lower surface of the anti-floating part 8, it remains in the frame 5 and is moved by the advance of the immersion extrusion part 7 by the contracting force of the tension coil spring 11. The whole advances and becomes ready for use again.

Second Embodiment

Next, a second embodiment shown in FIGS. 7 and 8 will be described.

This second embodiment is configured to be slightly smaller than that of the above-described first embodiment, so that the unit of the iron needle 6 can be extended three times.

As shown in FIG. 8, both sides of the front part of the frame 5 are bent inward to bend, and the anti-floating parts 8 and 8 of the needle bar 6 are provided in parallel on the sliding groove 15. will be. Each part other than the frame 5 is substantially the same as that of the first embodiment. For this reason, since the lengthening and use method of the iron needle 6 are also the same as that of 1st Example, description is abbreviate | omitted.

Third Embodiment

Next, a third embodiment shown in FIGS. 9 and 10 will be described.

The third embodiment is designed to be able to hold two (100) iron needles in the same shape as that of a conventionally used filing machine for one (50).

In the handle 1, the upper central part of the pushed blade 2 which has been tightened is cut outward to form a hanging protrusion piece 4.

Next, as shown in FIG. 10, four frames 5 each have four annular anti-floating portions 8 at intervals shorter than the length of a single needle inwardly on both sides of the front portion, respectively. The immersion extruded part 7 is inserted into the gap with sliding back and forth.

As shown in Fig. 9, the immersion extrusion portion 7 forms an iron squeezing portion 10 at the front end of the main body of the synthetic resin material. At the rear of the iron squeezing and pressing part 10, a hooking protrusion 12 for hanging the tension coil spring 11 is provided, and a folded portion 13 is formed at the rear part again. Tensile coil springs are projected on both sides of the projection protrusions (not shown), and inserted into sliding grooves 15 provided on both sides of the frame 5, and then placed on the immersion extruded portion 7 by the extension coil springs. One end of (11) is stopped, the middle part is wound around the folded portion 13, and the other end is connected to the hanging stone piece 4 provided on the pressing blade 2.

For this reason, the needle-extruded part 7 is always stretched forward, so that the iron needle 6 loaded in the front part of the needle-extruded part 7 can be pushed forward.

In this embodiment, the bottom plate 21 is not provided. Since the third embodiment is constituted as described above, when the handle 1 is opened to replenish and lengthen the needle bar 6, the tensile coil spring 11 and the squeezed out part 7 are dotted lines shown in FIG. Since it moves to the position of, the needle bar 6 can be easily extended.

In addition, since it is the same as that of what was demonstrated in 1st Example, it is abbreviate | omitted.

[Example 4]

A fourth embodiment of this invention will be described with reference to FIG. In this fourth embodiment, as in the third embodiment, the needle bar 6 is extended in length (100 pieces), and the rib-shaped floating prevention part 8 is cross-sectioned by the pressing process on both sides of the front part of the frame 5. And at the back of the annular flotation prevention portion 8, at the same time, the sliding groove 15 is formed by slit, that is, cut out. In addition, since each structure and usage method other than the frame 5 are the same as that of 3rd Embodiment, description is abbreviate | omitted.

Other Examples
