Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a display plate that is attached to various products such as clothing, bags, daily necessities, etc., and displays the product name, manufacturer name, size, pattern, etc. This invention relates to manufacturing equipment.

(Prior art) The present inventor filed an earlier utility model registration application
-84977 Publication), ``A woven fabric that is attached to a product such as clothing to display the product name, manufacturer name, size, etc. The paper proposes a display plate in which a zigzag, wavy, or other edging pattern is formed on part or all of the fused cut to prevent the cut from unraveling.

The purpose of the invention related to this earlier application is to fix the display plate to the display area of a flat product so that the mounting part does not become bulky and damage the skin of the user of the product. The purpose of the present invention is to improve the conspicuousness of the display plate by forming a border pattern on a part or all of the periphery of the display plate to prevent it from unraveling.

There are various methods for manufacturing this display plate. For example, there is a method in which the display plate is cut with pinking scissors and then the cut ends are welded with an electric iron or a heater.

(Problem to be solved by the invention) However, when cutting using pinking scissors,
The method of welding with an electric trowel not only has poor working efficiency, but also tends to cause unevenness in the thickness of the cut end during welding, making it difficult to make the processed product uniform.

Additionally, fusing devices using heaters have conventionally been capable of only making straight cuts, and it is impossible to form fusing cuts into jagged, wavy, or other edging patterns as in the display plate according to the above-mentioned invention. In addition, since a heater is used as a heat source, there are places where the material to be melted becomes hard due to rapid heating, making it unsuitable for forming a display plate with a uniform thickness.

In order to solve these problems, the present inventor carried out fusing processing using the "manufacturing apparatus for woven fabric material made of chemical fibers" proposed in a previous application (Japanese Patent Application No. 61-274991). It is also possible.

However, the manufacturing device according to the present invention can be replaced with a T ultrasonic transmitter, and is equipped with a curved cutting edge at the center of the circumference, and is provided with anti-unraveling at both ends of the cutting edge at the same angle of inclination. This method is suitable for cutting sheet materials in a linear manner, but the fusing method using such processing rolls does not meet the above-mentioned idea. It is not suitable for so-called cut-out processing, in which woven fabric such as display plates is cut into rectangular shapes, polygons, circles, etc., and zigzags, waves, or other border patterns are applied to part or all of the cut edges. It is.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to prevent the melted cut edges from becoming hard and to have a uniform thickness, thereby making it possible to form a more delicate border pattern. An object of the present invention is to provide a display plate manufacturing device that can also perform cutting processing.

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems are as follows: ``The sheet material T on which the product name, etc. is displayed is melt-cut into a predetermined shape, and at the same time A manufacturing device 100 for a display plate M that forms a predetermined pattern on a part or all of a cut C by a method, wherein the display plate M has a planar shape 4 on which the predetermined shape and the predetermined pattern have been applied.

According to the predetermined shape and predetermined pattern applied to 5, the welding and melting are reliably performed.

In this manner, in the display plate manufacturing apparatus 100 according to the present embodiment, when the pedal 36 is depressed, the mold material 45 moves downward, and the tape-shaped chemical fiber cloth T disposed on the base 22 is moved into the notch 23. At the same time, the starting sensor 39 detects the downward movement of the forming material 45 and moves the ultrasonic generator 15 along the notch 23 while contacting the chemical fiber cloth T, and furthermore, the stop sensor 20a , 20b detects that the ultrasonic generator 15 has moved by a predetermined distance and stops the movement of the ultrasonic generator 15, thereby welding and cutting the chemical fiber cloth T to display the display as shown in FIG. The plate M is configured to be manufactured automatically.

Next, the usage method and operation of the display plate manufacturing apparatus 100 according to this embodiment will be explained.

First, an operator places a tape-shaped fiber cloth T on which a product name and the like are displayed so as to hide the notch 23 on the base 22. When the pedal 36 is stepped on, the profile 45 moves downward via the support arm 30 and comes into close contact with the fiber cloth T, and the start detector 37 presses the sensing roller 40 of the limit switch 39 to generate a start signal. do. This starting signal causes the motor 11 to rotate forward, the ultrasonic generator 15 begins to move leftward along the notch 23, and the first stop detector 19a presses the sensing roller 21a of the first stop switch 20a. The limit switch 20a then moves until it generates a stop signal. During this movement, the emission port 15a of the ultrasonic generator 15 moves while coming into contact with the fiber cloth T, so that the fiber cloth T is fused to the shape of the shape material 45, and the cut portion C to be fused at the same time follows the pattern of the shape material 45. By welding, a display plate M as shown in FIG. 6 is manufactured.

Next, after the operator releases the pedal 36 and moves the shape material 45 upward, the fiber cloth T is manually cut into the notch 2.
3 to the left so as to hide it, and step on the pedal 36 again. Then, the shape member 45 moves down and comes into close contact with the fiber cloth T, and at the same time, the motor 11 is reversed by the start signal from the start limit switch 39 and the ultrasonic generator 15 begins to move to the right, and the second stop detector 19a presses the sensing roller 21a of the second stop limit switch 20a to generate a stop signal, the ultrasonic generator 15 stops. During this movement as well, the same fusing and welding operation as described above is performed, and a display plate M having a wavy border pattern on the cut edge C is manufactured.

In this manner, the display plate manufacturing apparatus 100 according to the present embodiment operates in the following steps: "Moving the fiber cloth T→Depressing the pedal 36→The ultrasonic generator 15 moves to the left and fusing and welding→Releasing the pedal 36→ Move the fiber cloth T → step on the pedal 36 → the ultrasonic generator 15 moves to the right to fuse and weld → release the pedal 36 →
By repeating the operation of ``moving the fiber cloth T'', a large quantity of display plates M having a wave-shaped border pattern formed on the cut C by fusing is produced.

Note that in this embodiment, the ultrasonic generator 15
By using a shape material 45 that is movable only in the direction that intersects the longitudinal direction of the tape-shaped fiber cloth T, and that has a border pattern applied only in the direction that intersects the tape T, the product name The manufacturing apparatus 100 for the display plate M is described in which a tape-shaped fiber cloth T is cut and welded in the longitudinal direction of the tape. By making the generator 15 movable in the longitudinal direction of the tape and controlling it with a computer, a woven fabric T as shown in FIG.
It can be easily applied to the so-called cutting process of woven fabrics, in which a woven fabric is melt-cut into rectangular shapes, other polygons, circles, etc., and a zigzag, waveform, or other edging pattern is applied to part or all of the cut C by the melt-cutting. I can do it.

Further, in this embodiment, the means for moving the fiber cloth T and the means for vertically moving the shape material 45 are performed manually, but for example, the vertical movement of the shape material 45 is not performed by a link mechanism using the pedal arm 35, but by a foot switch. The solenoid is driven by an electric signal and the mold material 4
Of course, by automating these processes such as moving the display plate M up and down, the display plate M manufacturing apparatus 100 can be made with higher productivity.

Furthermore, in this embodiment, the starting sensor 3
Although the limit switch 9 and the stop sensor 20 are configured as limit switches, it goes without saying that other detection means such as an optical sensor may be used.

The above description has been made of the case of fusing and welding chemical fiber cloth T, but it can also be applied to the case of welding and fusing other sheet materials T such as vinyl sheets and leather materials, as well as natural fiber cloth T. Also, by applying chemical treatment such as gluing, fusing and welding processing can be performed using the display plate manufacturing apparatus 100 according to the present invention.

Further, the present invention can be used to manufacture a colored display plate M by laminating a colored film on a fiber cloth T and fusing and welding them, or to produce a three-layer body T in which a fiber cloth is sandwiched between films. It can also be applied to a device that performs fusing and welding to prevent the film from peeling off.

(Effects of the Invention) As described above, the present invention supplies a sheet material so as to be in close contact with a planar shape material having a predetermined shape and a predetermined pattern. An ultrasonic generator that moves along the line melts the sheet material into a predetermined shape, and at the same time forms a predetermined pattern on the cut end to prevent the cut end from unraveling.A starting sensor also causes the shape material to close tightly to the sheet material. The ultrasonic generator is configured to start the ultrasonic generator by detecting that the ultrasonic generator has moved a predetermined distance, and to stop the ultrasonic generator by detecting that the ultrasonic generator has moved a predetermined distance.

Therefore, if the manufacturing apparatus according to the present invention is used,
The melted cut edges do not become hard and have a uniform thickness, making it possible to easily manufacture a display plate with a more delicate border pattern.

Furthermore, since the display plate manufacturing apparatus according to the present invention has a movable ultrasonic generator for fusing and welding, it is possible to easily cut out woven fabric, and to produce shapes different from conventional ones. It is possible to process it into a display plate.

Furthermore, since the shape to be fused and the pattern to be welded are applied to the planar material, the process of forming the pattern is easier than the conventional process of applying the pattern to a processing roll, making it easier to manufacture the material. Cost can be reduced.

In addition, the start sensor and stop sensor can detect the work situation and automatically weld and cut the sheet material, which can significantly reduce work efficiency.
