A mounting roller 32 for mounting the sequin attachment film 13 and the fiber fabric 14, respectively; A heating roller 17 which is rotated by the drive motor 18; A pressure roller 16 in close contact with the heating roller 17 and provided with a pressure cylinder 15; A cooler 19 for cooling the heated fabric; A separation roller 21 for winding the sequined fiber fabric 14 and the auxiliary film 22 in each of the winding rollers 33; It consists of a sequin attachment device consisting of a drive motor 20 for driving this.

Looking at the process according to the subject innovation processing apparatus of the above configuration as follows.

Color and aluminum vacuum from the hot melt adhesive layer on the top surface by a laser while continuously supplying a sequin film formed by sequentially laminating an auxiliary adhesive layer, a colored and aluminum vacuum deposition layer, a sequin film layer, and a hot melt adhesive layer on the auxiliary film. A laser cutting process of cutting the desired shape up to the deposition layer;

A separation step of transferring the partially cut sequin film to a pressurizing and conveying roller operated by a motor to leave a sequined attachment film leaving only a shape cut by a laser;

An attachment step of passing the sequin attachment film and the fiber fabric together through a pressure roller and a heating roller to thermally melt and attach the sequins to the fabric;

It is made of a separate winding process of winding the fabric and the auxiliary film attached with sequins by cooling with a cooler.

Hereinafter, look at the operation of the present invention.

First, when producing sequin paper using the manufacturing method and apparatus of the present invention, first, the auxiliary adhesive layer 31, the coloring and aluminum vacuum deposition layer, and the sequin film layer 29 on the auxiliary film 22 as shown in FIG. ), The sequin film 4 formed by laminating the hot melt adhesive layer 28 is mounted on the mounting roller 32 of the sequin processing apparatus, and then the apparatus is operated.

The sequin film 32 mounted on the mounting roller 32 has a film feed roller 7 and a pressure roller 8 which are rotated by the operation of the motor 6 while maintaining a proper tension by the film tension adjusting device 5. ) Moves toward the scan head 2 side of the laser generator 1.

As the film 4 for the sequins passes through the scan head 2 and is radiated from the scan head 2, only the heat-melting adhesive layer 28 to the vacuum deposition layer 30 as shown in FIG. 5. Incision is made in the desired shape.

The sequin film 4 cut in this way is separated into separable film 13 and waste film 13 to be attached to the fabric as shown in FIG. It is wound up in (33).

When the sequin attachment film 13 and the wire oil fabric 14 are mounted on the mounting rollers 32 of the fabric processing apparatus, and the power is applied to the device, the driving motors 18 and 20 operate, and the fiber fabric 14 And the sequin attachment film 13 are interviewed and pass between the pressure roller 16 and the heating roller 17.

At this time, since the sequins attaching surface of the sequins attaching film 13 is interviewed with the fiber fabric 14 surface and passes through the heating roller 17 and the pressure roller 16, the hot melt adhesive layer 28 of the sequins is melted by heat and pressure. It is attached to the fiber fabric (14).

When the fiber fabric 14 and the sequin attachment film 13 pass through the pressure roller 16 and the heating roller 17 in this manner, the fiber fabric 14 and the sequin attachment film 13 heated to the heating roller 17 are Is cooled by the cooler (19).

The cooled fiber fabric 14 and the sequin attachment film 13 are wound on the winding rollers 33 by respective separation rollers 21, wherein the heat-melting adhesive layer 28 and the fiber fabric 14 of the sequins are wound. Since the adhesive force is greater than the adhesive force between the auxiliary adhesive layer 31 and the auxiliary film 22, the sequins are separated from the sequin attachment film 13 and attached to the fiber fabric 14.

Hereinafter, look at the action and principle of operation of each member of the present invention.

As a material for the film having a gloss pattern, a colored layer having a thickness of several micrometers is added to a polymer compound such as polyester having a thickness of several tens of micrometers, or aluminum is vacuum-deposited on a film, a holographic pattern is added, and then the colored layer is added to obtain a light reflection effect. It is made of material.

In the present invention, a method of making a sequin by cutting into a pattern to express a film was used a carbon dioxide laser. In the case of a carbon dioxide laser having an oscillation wavelength of 10.6 µm, the absorption of the polymer compound is excellent regardless of whether visible light is transmitted or not. Machining efficiency is very high.

The temperature of the portion irradiated with the laser light focused on a small area by the condensing lens is rapidly increased to cut by temporarily vaporizing and removing the material to be processed.

In particular, the laser is a high-energy light, so high-speed processing is possible, and low heat input prevents the surrounding heat deformation and precisely controls the intensity and time of the output.

In particular, the Galvanometer type scan head minimizes the inertia of the moving part to speed up the processing speed.

4 is a view of a general Galvanometer type scanhead and its operation principle is as follows.

The laser beam 3 output from the laser generator 1 is reflected by reflectors attached to two Galvanometer scanners through a variable focusing apparatus 25 having a variable focal length and continuously focuses on a plane.

At this time, the position of the focus varies according to the rotation angle of the Galvanometer scanner, but the focus is always positioned on the same plane by the variable focusing apparatus 25, and the rotation angle of the scanner is determined by the input data.

The control relationship between the laser generator 1 and the scanner is shown in FIG.

The laser generator 1 used in the present invention is a gas-tight type of RF excitation method, and the output is easily controlled and the generation and stop of the laser light are easily controlled.

The main part of the sequin cutting device is composed of a plurality of carbon dioxide laser generators (1) and a scan head (2). The laser consists of an RF-excited power supply unit and a hermetic resonator. Focusing on the sequin film is via a scanhead 2 consisting of movable reflectors 27 connected to two Galvanometer scanners 26 axes.

The reflector 27 of the scanner has a small mass and low inertia, so that a high speed movement is possible.

The user draws the desired pattern using general drawing software, converts it into a vector scan format in the scanhead driving program, and moves the movable mirror and the variable focus lens to cut the film.

At this time, the variable focus lens automatically adjusts the focal length so that the laser beam always focuses on the film surface.

Multiple laser generators and a combination of scanheads are placed side by side to cut a film of the same width as the width of the fabric, and the cutting widths overlap slightly so that the patterns are connected.

The sequin film 4, which is a material of the sequin, is made by laminating an auxiliary film for maintaining the relative position of the sequin film and the cut sequin with a suitable adhesive layer. It is connected to the film tension control device (5) with a belt.

The film transported by the film driving roller 7 driven by the servo motor 6 precisely controlled by the controller and the roller 8 pressed by the pressure cylinder 9 is carried out by the laser light 3 by the PC. The design is cut into the input.

At this time, by adjusting the output parameter of the laser and the feed rate of the film is adjusted to cut only the film layer for the sequins.

The film transfer is intermittent or continuous depending on the type of pattern.

The input pattern has a certain size, so if you keep repeating the same pattern, the same pattern is repeatedly cut at regular intervals.

The film tension holding roller 10 is a roller for keeping the film taut at all times and is supported by a spring.

The finished film is wound and separated into a part used as a sequin and a margin part by a separation roller.

The separable adhesive film 13 wound up is to have the hot melt adhesive-coated part face upward and the fiber fabric 14 is interviewed on the upper film with the sequins cut by the laser on the auxiliary film. .

When the sequin attached film 13 and the fiber fabric 14 are laminated to the auxiliary film and pressure and heat are applied, the sequins attached to the auxiliary film are attached to the fiber fabric 14 and the respective winding rollers ( 33).

Between the heated pair of rollers (16) and (17), the fabric (14) and the sequins that are compressed are attached to the fabric by means of a hot melt adhesive, and after the cooling process, the fabric and the auxiliary film are separated again. As the separation occurs between the secondary film and the low adhesive strength, and each of the re-winding it is possible to obtain a high-precision paper with a brilliant color and luster according to the pattern and material of the sequins.

As described above, the present invention cuts sequins having a high gloss color or light reflection effect on the surface of a garment and other fabrics into a free shape without using a mold, and attaches them collectively. Precision patterns can now be economically pasted into fabrics.

As described above, the present invention is a sequin processing apparatus for separating the sequin film into a shape desired by the user using a carbon dioxide laser to separate the sequin attachment film to be attached to the sequins attached to the fabric and the waste film. It consists of a fabric processing device that heat-melts the sequins attached to the sequins attaching film to the fabric, and the surface of the sequins is smooth and firm, so that the gloss and durability are high, and the sequins of complex shape can be manufactured. Sequins can be made and attached to the fabric to maximize productivity while minimizing defect rates.
