Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a temporary fixing device that is applied when overlapping and temporarily securing fabrics to be sewn or when overlapping and temporarily securing multiple sheets of paper. Regarding.

[Prior art] In the past, a steel pin was inserted along the fabric surface into the seamed part of the VI-made fabric to temporarily fix the fabric, and a steel pin was inserted into the stitched part of the paper. The paper was temporarily secured by piercing it along the surface of the paper.

[Problem to be solved by the invention] When fabric is temporarily fixed with a gusset of [1], the tI4 gusset is very hard and lacks punctuality, so the needle of the sewing machine may break during sewing. In order to prevent damage to the cloth cutter, it is necessary to remove the gusset from the cloth while sewing, resulting in a significant decrease in productivity. When disposing of paper using an OAR device such as a shredder, it is necessary to remove the insect pins from the paper in order to prevent the cutter from being damaged by the insect pins, which poses a problem in that removing the insect pins is complicated.

Furthermore, since the tips of the pins and insect pins are sharp, there is a risk of injuring the fingers of workers, and there is also the problem that they tend to generate chips that stain fabrics and paper.

The present invention aims to solve the above problems.

Means for Solving Problem EXI] The temporary fixing device of the present invention has a main body in which a case for storing a synthetic resin filament is connected, and the filament pulled out from inside the case is inserted through the main body. A stabbing needle having an insertion hole extending vertically through the main body is inserted so as to be able to move forward and backward in the longitudinal direction and to be able to protrude toward the front of the main body,
In the main body, there is an intermittent feeding mechanism for pushing the filamentous body in synchronization with the forward motion of the stabbing needle when the stabbing needle moves forward, and sending out the vicinity of the tip of the filamentous body toward the front of the main body. and a cutting mechanism for cutting the fed filament near the front end inside the main body to form a temporary fixing pin.

[Function 1: A sheet to which the stab needle is temporarily fixed, with the vicinity of the tip of the synthetic resin filament and a part of the stab needle into which the filament is inserted protruding forward of the main body. After piercing the body, the piercing needle is moved back leaving the vicinity of the tip of the filament, and the vicinity of the tip of the filament is pierced through the sheet body, and in this state, the filament is inserted into the sheet body. A temporary fixing pin is formed by cutting at a slightly rearward position, and the separated temporary fixing pin is released outside the main body, and the sheet body is temporarily fixed by the temporary fixing pin.

[Effect of the Invention 1] Since the present invention is configured as described above, it is possible to accurately and easily temporarily fasten a sheet such as cloth or paper while forming a temporary fastening pin, and the cost of the temporary fastening pin can be reduced. In addition to saving money, since the sheet body can be sewn or cut while being temporarily fixed with the temporary fixing pin, there is no need to take out the temporary fixing pin from the temporarily fixed sheet body, and subsequent work is saved. This has the effect of streamlining the process.

In addition, fingers etc. may be injured by the temporary fixing pin,
In addition to being able to eliminate the problem of rust, the temporary fixing pin can be colored in any color to enhance the design effect of the temporary fixing pin.

When the slide lever 3 is pushed forward and moved forward, the filament 4 is pushed by the latch 3b and is pushed forward.
At the same time as the vicinity of the tip 4a of the filament 4 is fed out to the front of the main body 12, the stabbing needle 1 advances in synchronization with the filament 4 along with the slide lever 3 by the forward stroke of the slide lever 3 from the start position, and stabs. The front and central portions of the needle 1 are projected forward of the main body 12 with the filament 4 inserted therein (see FIG. 4(A)). When the slide lever 3 is released in this state, the stabbing needle 1 moves back together with the slide lever 3, leaving the vicinity of the tip 4a of the filament 4 protruding forward of the main body 12, and returns to the starting position (fourth
(See figure (B)).

A cutter 2 that also serves as a press is installed at the front end of the main body 12 so that it can be pressed down to cut the filament 4 to a certain length and apply downward pressure to the vicinity of the rear end of the cut filament 4. The cutter 2 is held so as to be slidable in the vertical direction on a guide protrusion 22 protruding near the front end of the inner surface of the side plates 12d of the main body 12. A spring 2o suspended between the cutter 2 and the side plate 12d of the main body 12 urges it upward in order to return it from the depressed end position to the original position. A protruding edge 2a for cutting the filament 4 is formed on the rear end of the lower surface of the cutter 2, and a downward pressure is applied to the vicinity of the rear end of the cut filament 4 near the front lower part of the cutter 2. A press portion 2b for pressing the cutter 2 is formed in a right-angled shape, and a knob 2d inserted through the forward and backward hole 17 is provided on the upper surface of the cutter 2 in order to press down the cutter 2. Knob 2d-
1- When the cutter 2 was pressed down by operation, the cutter 2 was formed at the lower front end inside the main body 12! When the cutter 2 is plunged into the space 6 and released, the cutter 2 automatically returns to the upper moving end by the elastic force of the spring 20.

A temporary fixing pin P having a pull-out stop P1 bent at right angles is formed by being sandwiched between the bending guide 13 and the bending guide 13 and bent downward at right angles (see FIG. 4(C)). The temporary fixing pin P can be ejected from the main body 12 through the outlet 15 (see FIG. 4(D)).

Next, the operation and effects of the embodiment having the above configuration will be explained.

When temporarily fixing a sheet body S such as cloth or paper using the temporary fixing device 11K, the slide lever 3 is pushed forward to send out the vicinity of the tip 4a of the filament 4 toward the front of the main body 12, and to pierce it. Move needle 1 to the forward end and stab needle 1
The tip portion 4 of the filament 4 is placed inside the front and center portions of the
The piercing needle 1 is passed through the sheet body S which is temporarily fixed in this state parallel to the sheet surface, and then the slide lever 3 is released. The needle 1 retreats leaving the vicinity of the tip 4a of the filament 4 and is removed from the sheet body S, and the vicinity of the tip 4a of the filament 4 is held in a state of being pierced through the sheet body S. Furthermore, when the cutter 2 is pressed down in this state, the filament 4
is cut by the edge 2a of the cutter 2 at a slightly rearward position near the tip 4a, and the tip 4a of the filament 4 is separated, and the part near the rear end of the separated filament 4 is attached to the press portion 2b of the cutter 2. The temporary fixing pin P is formed by bending at right angles by the bending guide 23 and the temporary fixing pin P.
When the temporary fixing pin P is released outside the main body 12 in a state in which the sheet body S is pierced, the sheet body S can be temporarily fixed by the temporary fixing pin P.

Therefore, while forming the temporary fixing pin P, the sheet body S can be easily and accurately temporarily fixed with the temporary fixing pin P, and since the temporary fixing pin P is made of synthetic resin material, it is possible to temporarily fix the sheet body S with the temporary fixing pin P. If you use the temporary fixing pin P to temporarily fix the stitched parts of the fabric or the threaded parts of the paper, you can use the temporary fixing pin P to cut the temporarily attached fabric with a sewing machine or cut the temporarily attached paper with a shredder, etc. Sewing needles and cloth cutters,
This solves the problem of the shredder's cutter being broken or damaged by temporary fixing pins.

Therefore, the temporary fixing pin P can be made of N or cut while being pierced through fabric, paper, etc., and there is no need to make the temporary fixing pin P of 5ill or remove it before cutting. The cutting process can be streamlined.

In addition, since the temporary fixing pin P is made of a relatively soft synthetic resin material and its end is not formed into a sharp shape, it is possible to avoid the risk of the worker's fingers being injured by the temporary fixing pin P. At the same time, since rust does not occur on the temporary fixing pin P, there is an effect of preventing the temporary fixing portion from becoming soiled with rust.

Plus, synthetic trees! 11 is cut to form the temporary fixing pin P, and at the same time the sheet body is temporarily fixed using the temporary fixing pin P. Therefore, the cost of the temporary fixing pin P can be significantly reduced, and The design effect of the temporary fixing pin P can be enhanced by coloring the fixing pin P in an arbitrary color.

In the above embodiment, an electric heater may be provided instead of the cutter 2, and the filament 4 may be cut by this electric heater.
