The present invention relates to an attachment method for attaching a spangle to a surface of a fabric, and more particularly, to a spangle attachment method for attaching a spangle to a surface of a fabric using pneumatics.

Generally, a spangle means a shiny small piece and is made of a polyester material and is about 30 μm to 100 μm thick. Such spangles may have a color coating coating on the surface thereof to reflect light, and a hot-melt adhesive may be applied on the back side. These scoops are made in the form of rolls for ease of use and handling.

These spangles are mainly attached to clothes such as banquet or stage clothes of the social and entertainment worlds, and are visually fantastic and bright decorative aesthetics by reflecting light or surrounding light.

The spangles used for such applications can be implemented in various forms to adhere to various fabric surfaces. However, the spangles using hot melt adhesives and the method of attaching spangles to the embroidery machine can be used. It can be called a method. The adhesive method using the hot melt adhesive is spangled by a cutter that can selectively produce a spangled film coated with a hot melt adhesive on the back surface of the color coating layer, for example, a circle, an ellipse, and a triangle. The film is press-cut and mechanically bonded to the adhesive layer on the surface of the fabric.

The hot melt adhesive is melted by a hot plate maintained at a temperature range of 170-175 ° C. at all times by a bimetallic temperature control device, and the melting point of the hot melt adhesive is 150 ° C.

The method of attaching the scoop to the fabric surface with the embroidery machine is a method of sewing a scoop of the cut to a certain size by the embroidery machine. The prior art according to the method of attaching the spangles using an adhesive will be described mainly.

Conventional attachment methods and attachments for attaching a spangle to a fabric are shown in FIGS. 1 and 2 as shown in FIG. 1, which schematically shows only the main parts of the device for attaching the spangles to the fabric surface. 2 is a partial cross-sectional view showing a cut portion of the cutter assembly and the die assembly shown in FIG.

1 and 2, mounted on a pair of guide shafts 11 and 12 vertically perpendicular to the plane of the base 10 and operated by the hydraulic cylinder 13, the cutter 14 at the bottom thereof. A cutter assembly (16) comprising a plurality of elongated pressure pins (15); A die assembly 23 mounted to the guide shafts 11 and 12 and including a fastening hole 20 for receiving the pressing pin 15, a sealing member 21 at an upper portion, and a buffer member 22 at a lower portion thereof. ); A rotatable feed reel 31 on which the spangle film 30 is wound; A recovery reel 32 for recovering the spent spangle film 30; Feed rollers 33 and 33a for transferring the recovery film 32 from the supply reel 31 to the spangled film 30; A rotatable feed drum 41 on which the fabric 40 is wound; A recovery drum 42 for recovering the fabric 40; A pin roller (43) (43a) for transferring from the supply drum (41) to the recovery drum (42); It consists of the hotplate 50 which maintains a predetermined temperature by the bimetallic temperature control apparatus.

Looking at the operation structure of the linear spangle attachment apparatus configured as described above, the feed rollers 33, 33a and the pin rollers 43, 43a are interlocked by a motor (not shown), and the spangle film 30 The fabric 40 is transferred to the cutting position and the attachment position. In other words, the sequin film 30 is positioned between the cutter assembly 16 and the die assembly 23 by the transfer rollers 33 and 33a, and the fabric 40 of the die assembly 23 It is located between the lower portion and the hot plate 50. At this time, the feed rate ratio of the film and the fabric is not shown in the figure, but is linked to each other by a chain or timing belt to be transferred at a set rate.

When the film and fabric are supplied to the cutting position and the attaching position, the hydraulic cylinder 13 is operated so that the cutter assembly 16 fixed to the guide shafts 11 and 12 is placed on the guide shafts 11 and 12. It is lowered downward with the die assembly 23 by the inserted spring (S). The die assembly 23 descending downward is stopped on the surface of the fabric 40 by the stopper 17 to position the fabric 40 on the hot plate 50.

The cutter assembly 16, which is also lowered downward, cuts the spangled film 30 positioned below the cutter 14, so that the cutter member 16 is in communication with the complete member 22 of the die assembly 23. It is inserted into the fastening hole (20). At this time, the spangled film cut by the pressing pin 15 formed integrally with the cutter 14 discharges the spangled film 30 to the outside of the buffer member 22, the bottom surface of the complete layer member 22 Since the surface of the fabric 40 abuts, the cut spangle film 30 is pressed by the pressure of the pressing pin 15 to the surface of the fabric.

Accordingly, the fabric 40 positioned on the hot plate 50 has a hot melt adhesive of the spangled film 30 pressurized by the pressing pin 15 to be melted by the heat of the hot plate 50 and adhered to the fabric. At this time, the pressing time of the pressing pin 15 is performed in the range of about 0.3 seconds to 0.5 seconds.

When the spangled film is attached to the fabric surface, the assembly 16 and the die assembly 23 are replaced by the hydraulic cylinder 13, and the feed rollers 33, 33a and the pin rollers 43, 43a are used. New films and fabrics are resupplied at a set rate to repeat the above-described work process.

In the spangle attachment apparatus as described above, providing the spangle film and the fabric at a predetermined ratio and supplying them to the cutting position of the cutter and the pressing position of the pressing pin (a); (B) fixing the fabric located on the surface of the hot plate by a die assembly operated by a hydraulic cylinder; (C) cutting the spangled film supplied with the cutter of the cutter assembly operated by the hydraulic cylinder; And (d) pressing the cut spangled film onto the fabric surface located on the hot plate.

However, in the spangle attachment apparatus as described above, for example, when manufacturing a spangle having a small size, for example, a diameter of 7 mm or less, a pressure pin for pressing the fabric surface is bent or broken to produce a spangle. There is a limit in size, and during high speed driving, the hot melt adhesive is dissolved due to frictional heat between the fastening pin and the fastening hole of the die assembly. It is difficult to work because it is contaminated with adhesive on the film surface.

Therefore, there is no limitation in any form of spangles or sizes in attaching the spangles to the fabric surface, and there is a need for a spangle attaching device capable of performing continuous work without generating a defect of the product due to frictional heat.

The present invention has been invented to fundamentally solve the problems associated with such a conventional spangle attachment apparatus, the present invention has been described for exemplary purposes only, but various embodiments of the present invention will be apparent to those skilled in the art. And variations can be applied, but it is to be understood that they belong to the true spirit and scope of the present invention.

It is an object of the present invention to provide a method for attaching a spangle which can be attached using pneumatic to attach the spangle to a fabric surface.

Another object of the present invention is to provide a secondary effect, such as improving the productivity, reducing the mold manufacturing cost of the cutter and continuous work efficiency, since the spangles can be attached to the fabric using pneumatic pressure.

The method of attaching the spangles according to the present invention on the surface of the fabric will be described in detail with reference to FIGS. 3 to 6 as follows.

Referring to FIG. 3, FIG. 3 is an explanatory view illustrating an embodiment for attaching the spangles according to the present invention to the fabric surface, wherein the spangle film and the fabric feeding apparatus described in FIG. 1 have the same structure. Since the present invention will be mounted and operated, it will be described in detail with reference to the components of the device for attaching the spangles to the fabric surface using pneumatic pressure.

Cutter assembly 16 mounted on guide shafts 11 and 12 mounted perpendicular to the plain of base 10 and comprising a plurality of cutters 14, air injection port 18 and air suction port 19; )Wow ; The die assembly 23 including a plurality of fastening holes 20 of the sealing member 21 for accommodating the plurality of cutters 14 and a through hole 20b of the buffer member 22 parallel to the guide hole 20a in the coaxial direction. )Wow ; An air intake and exhaust control device 60 for opening and closing a passage between the air injection port 18 and the air intake port 19; A feed roller (33) (33a) for feeding the spangle film from the feed reel (31) to the cutting position and a pin roller (43) (43a) for feeding the fabric from the feed drum (41) to the spangle attachment position; A guide shaft (11) (12) comprising a spring (S) and a stopper (17) between the cutter assembly (16) and the die assembly (23); It consists of a hot plate 50 which is located in the plane of the base 10 and abuts the loose member 22 of the die assembly 23.

Looking at the operating structure of the device for attaching the spangles to the fabric surface according to the present invention configured as described above, as described in the prior art of FIG. 1, the spangle film 30 and the fabric 40 is supplied reel 31 And the cutting position and the spangle attachment position of the cutter 14, i.e., the cutter assembly 16 and the die assembly 23, from the feed drum 41 by the feed rollers 33, 33a and the pin rollers 43, 43a. And between the hot plate 50 and the loose member 22, respectively. The feed rollers 33 and 33a and the pin rollers 43 and 43a include a function of applying tensile force to the fabric and the film so that the feed rollers are supplied in an unfolded state. Operation of the hydraulic cylinder 13 causes the cutter assembly 16 to descend downward along the guide shafts 11 and 12, which are guided when the cutter assembly 16 descends. The die assembly 23 is also lowered by a spring S mounted on it and stopped by a stopper 17 on the fabric surface located on top of the hot plate 50.

At this time, the die assembly 23 presses and fixes the surface. The cutter assembly 16 cuts the spangled film 30 by the cutter 14 and at the same time the air intake port 18 (operated by the solenoid valve) of the air inlet / outlet control unit 60 is operated. Shut off the passage and open the air intake port 19. At this time, the air is moved toward the air suction port through the inner hole 14a of the cutter 14. Therefore, the film 30a cut by the cutter is coupled to the fastening hole 20 of the sealing member 21 in a state of being adsorbed to the end of the cutter 14. The cutter 14 and the fastening hole 20 are coupled to each other, and at the same time, the air suction port 19 is closed by the air suction and discharge control device 60 by a sensor (not shown), and the air injection port 18 is closed. Open the passage of pneumatically and inject air at about 5-10 PSI. However, the pneumatic pressure may change depending on the product characteristics. The spangled film 30 adsorbed to the end of the cutter 14 by the pneumatic pressure injected through the air injection nozzle is transferred to the through hole 20b of the buffer member 22. However, in order for the cut spangled film 30a to be transferred toward the through hole 20b of the buffer member 22, the injected pneumatic pressure is discharged toward the through hole, so that the through hole of the buffer member 22 is shown in FIG. 6. Since the X-shaped grooves 24 are formed so that the edges of the 20b communicate with each other, the pneumatic pressure injected through the X-shaped grooves 24 is discharged.

Therefore, the spangled film is adhered to the surface of the fabric by the discharged pneumatic pressure so that the hot Celtic adhesive of the spangled film 30A is dissolved by the heat of the hot plate 50 so that the spangles are attached to the surface of the fabric. The time when the spangled film 30a abuts on the fabric surface is within about 0.2-0.5 seconds.

After the spangled film 30a is attached to the fabric surface, the cutter assembly 16 and the die assembly 23 are raised to their original positions by the hydraulic cylinder 13. At this time, the spangle film 30 and the fabric 40 is newly supplied to operate the above-described work process repeatedly.

After all, the method of attaching the spangles according to the present invention; Supplying the spangle film and the fabric at a predetermined ratio to position the cutting position of the cutter and the cut spangle to be attached (a); (B) fixing a fabric located on the surface of the hot plate by a die assembly actuated by a hydraulic cylinder; (C) adsorbing a piece of the spangled film cut by the air suction / extraction device at the same time as cutting the film supplied with the cutter of the cutter assembly operated by the hydraulic cylinder; (D) transporting and pressing the spangled film cut at the end of the cutter to the fabric surface through the fastening hole of the die assembly; And (e) heating the hot melt adhesive of the spangled film abutted by pneumatic on the fabric surface to a predetermined temperature.

As described above, the spangle cut through pneumatic is placed on the fabric surface, so that the spangle film is fused by the heat of the hot plate, so there is no fear of generating frictional heat. Since the function is performed spontaneously, it is possible to produce a spangled film with a beautiful cut surface. In addition, the length of the cutter can be made very short, so that a spangled film having any desired size can be produced.

Therefore, it will perform a continuous and continuous work process at high speeds.
