The present invention relates to a laminating system and a temperature control method for adhering a hot melt adhesive film to a fabric so that the hot melt adhesive film is attached.

In order to develop a fabric having a complex function, and to form various designs, a technology of combining fabrics has been developed. Combined fabrics will have various characteristics and functions. In other words, clothing made of a combined fabric may exhibit improved efficiency at room temperature or moisture resistance, and may have a special texture that is rough on the outside but soft on the inside. In addition, even in the aesthetics of clothes, the characteristics of the fabrics of fabrics such as the color of the surface can be varied are very diverse. In general, the combined fabrics are used in a variety of materials from shoe uppers to automobile seats, and are expensive and expensive than general fabrics. Therefore, various types of systems have been proposed for the blending of fabrics such as paper, textiles and leather.

Korean Patent Laid-Open Publication No. 2001-0098074 "Method and fabrication method of fabric of fabric" After spraying an adhesive on the surface of any one of the two fabrics, two fabrics are passed through a pressure roller We propose a system that incorporates fabrics.

Republic of Korea Utility Model Registration No. 20-0243911 "Applicator for folds with multiple homogenization function" is the first to supply the first supply fabric to be combined and evenly select the adhesive supplied to the predetermined roller surface An adhesive attaching device for contacting and attaching one surface of the supply fabric, a fabric fabrication device for adhering the second supply fabric at a predetermined pressure to one surface of the first supply fabric to form a fabric fabric, and the fabricated fabric fabric It is proposed a system that is provided with a drying drum to dry in a predetermined state by combining two or more fabrics to improve the function of the fabric and increase the aesthetics.

Korean Patent Laid-Open Publication No. 2003-0095629 "Double-sided stacking method and double-sided stacker" is to pass the insert vertically upward between two adhesive feed rollers to apply the adhesive on both sides of the insert, the fabric on both sides of the insert By supplying the fabrics so that two fabrics are bonded to both sides of the insert at the same time, it is proposed a system that can simultaneously combine two fabrics on both sides of the insert, such as sponge, cotton.

On the other hand, it is proposed a product made by attaching a hot melt adhesive film on one side of the fabric so that various stickers having various patterns, decorative fabrics formed printed matter, emblems such as shoes, etc. can be adhered to the desired product. Such a product, as shown in FIG. 1, transfers the laminating system 100 while transferring the fabric 1, the hot melt adhesive film 2, and the release paper or release fabric (3; hereinafter referred to as “release fabric”) to coincide. The hot melt adhesive film 2 is attached to the lower surface of the fabric 1 through, and the release fabric 3 is separated to obtain a fabric with the hot melt adhesive film 2 attached thereto (hereinafter, referred to as 'foam fabric'). do. At this time, the release fabric (3) is formed of a material that is not attached to the hot melt adhesive film (2), in connection with this, the applicant of the Republic of Korea Patent Application No. 10-2005-0065823 "Silicone coated release fabric and its manufacturing method" It has been proposed a woven fabric woven with fibers through, and a release fabric coated in the order of polyurethane, silicone, hot melt adhesive film on the top.

As such, the laminating system 100 for manufacturing the fabric 5 has a frame having an inlet 112 and an outlet 104 into which the fabric 1, the hot melt adhesive film 2, and the release fabric 3 are joined together. Disposed by the drive roller 122 and the driven roller 124 in the 110, the conveying belt 120 supported by a plurality of intermediate rollers 126 up and down to match the fabric (1), hot melt adhesion The film 2 and the release fabric 3 are compressed to be transferred from the inlet 102 to the outlet 104. And the heating element 130 is installed in the frame 110 so that the hot melt adhesive film 2 is bonded to the fabric (1) by heat.

By the way, the conventional laminating system 100 has room for improvement in terms of maintaining the quality of the composite fabric (5) stably. In other words, in order to ensure that the fabric 5 has a stable quality, the hot melt adhesive film 2 should be uniformly adhered to the fabric 1, but the conventional laminating system 100 should set process conditions through the judgment of the operator. There was a problem. That is, the operator adjusts the temperature of the heating element 130 while checking the state of the fabric fabric 5 in which the process proceeds, thereby setting the process conditions, resulting in waste of fabric and working time during initial setting, Therefore, there is a problem that the quality of the product is determined.

In addition, even if the working conditions change due to the malfunction of the system, the surrounding environment could not be immediately responded to the problem that was confirmed in a state in which the wrong process is advanced to some extent.

The inventors have come to the conclusion that various tests have shown that this problem is caused by the temperature control portion of the conventional laminating system 100. The conventional laminating system 100 sets the temperature of the heating element 130 to a predetermined range (about 100 ℃ to 140 ℃) and proceeds. Of course, such a process temperature is set according to the type of fabric 1 and the hot melt adhesive film 2 used. At this time, the conventional laminating system 100 is to control the temperature by detecting the temperature in the frame 110 and the surface temperature of the transfer belt 120 in the frame 110. However, the process conditions of the laminating system 100 is the temperature setting according to the external environmental change is the most important factor. In particular, since the temperature difference between the summer and winter occurs up to 40 ° C., even if the same set temperature is performed at 5 m / s, the temperature deviation of the fabric 5 coming out of the outlet 104 of the laminating system 100 is 30 ° C. It is abnormal. In general, when the process temperature is excessive, the fabric 1 is deformed or damaged, and when the process temperature is low, poor adhesion between the fabric 1 and the hot melt adhesive film 3 occurs.

Therefore, the present invention improves such a conventional laminating system and its control method, and easy to set the process conditions, laminating system for adhering a new type of hot melt adhesive film to the fabric, which can facilitate the quality control of the fabric fabric and its It is an object to provide a temperature control method.

In particular, the present invention provides a laminating system and a temperature control method for bonding a hot-melt adhesive film of a new type to the fabric to ensure a stable temperature required for the process even in the malfunction of the heating element and changes in the external environment of the laminating system.

3 is a view for explaining a laminating system for adhering a hot melt adhesive film to a fabric according to a preferred embodiment of the present invention, Figure 4 is a plan view of the laminating system shown in FIG.

2 to 4, the laminating system 10 according to a preferred embodiment of the present invention includes a frame 20, a transfer belt 30, a heating element 40, a surface temperature detector 50 and a controller 70. It is provided with. In this case, the frame 20 has an inlet 22 and an outlet 24 into which the fabric 1, the hot melt adhesive film 2, and the release fabric 3 are joined together. The conveying belt 30 is installed in the frame 20 and rotated by the driving roller 32 and the driven roller 34, and a plurality of intermediate rollers 36 disposed between the driving roller 32 and the driven roller 34. Supported by the) and the matched fabric (1), hot melt adhesive film (2) and the release fabric (3) is pressed so that the transfer from the inlet 22 to the outlet (24). The heating element 40 is installed in the frame 20 so that the hot melt adhesive film 2 is welded to the fabric 1 to generate heat to form the fabric 5.

The laminating system 10 according to the present exemplary embodiment has three temperature sensors 60, 62, and 64 on the supporting column 52 installed perpendicular to the conveying direction of the cloth fabric 5 near the outlet 24. The surface temperature detection unit 50 is installed to measure the surface temperature of the cloth fabric 5 so that the value is transmitted to the control unit 70. The supporting column 52 is coupled to the frame 20 across the top of the cloth fabric 5 so that it is disposed perpendicular to the conveying direction of the cloth fabric 5. Of course, the supporting column 52 may be manufactured separately from the frame 20 and placed on the ground.

The surface temperature detector 50 of the laminating system 10 according to the present embodiment includes a first temperature sensor 60, a second temperature sensor 62, and a third temperature sensor 64. At this time, the first temperature sensor 60, the second temperature sensor 62 and the third temperature sensor 64 are sequentially installed in a direction perpendicular to the traveling direction of the composite fabric 5, in Figures 3 and 4 The surface temperature of the central portion and both sides of the polyfoam fabric 5 is detected and transmitted to the control unit 70, such as the area of the double-dot chain line displayed on the polyfoam fabric 5. The reason for installing three or more temperature sensors is to consider the heat supply characteristics of the heating wire that is usually used as the heating element (40). In other words, since the heat wires are usually supplied with a large amount of heat from the left and right sides, a heat wire with a strong heat supply is used at the middle portion. Therefore, the present embodiment is installed three or more temperature sensors in order to control the heating element 40 so that the heat supply is made uniform in all parts to enable a constant quality control. By such a configuration, the laminating system 10 according to the present exemplary embodiment may determine disconnection of the heating element 40 when there are many temperature differences between the left and right sides and the middle portion. The surface temperature detection unit 50 configured as described above may prevent the temperature setting and the excessive temperature setting by detecting the temperature of three points of the cloth fabric 5 that has passed through the heating portion for more precise mixing.

On the other hand, the temperature sensor for measuring the surface temperature has the advantage that can determine the disconnection of the heating element 40 to supply heat to the laminating system 10 as well as to measure the temperature of the resulting fabric fabric (5). For example, assuming that the temperature of the fabric fabric 5, which is derived from setting 100 ° C. to the transfer belt 30 when the external temperature is 25 ° C., is 110 ° C., when the deviation is more than 20 ° C., the heating element ( It is concluded that the heat supply due to the disconnection of 40) is not smooth. Therefore, in the related art, the frame 20 must be completely opened to separately measure whether short circuits of 20 or more heating elements 40 are separately. However, the present invention can indirectly determine whether the heating elements 40 are short-circuited to reduce adhesion defects. It can be.

In the temperature control method of the laminating system 10, the surface temperature detection unit 50 in which the first temperature sensor 60, the second temperature sensor 62, and the third temperature sensor 64 are first installed in the supporting column 52. Is installed so as to be close to the outlet 24 from the outside of the frame 20 and connected to the control unit 70 for controlling the temperature of the heating element 40 to the outside of the composite fabric 5 is transferred to the outside through the outlet 24 The surface temperature is measured by the surface temperature detector 50 so as to be transmitted to the controller 70. At this time, the surface temperature of the fabric 5 to be managed is input to the controller 70 before the process proceeds. After the preparation is completed, the surface temperature of the composite fabric 5 input from the first temperature sensor 60, the second temperature sensor 62, and the third temperature sensor 64 of the surface temperature detection unit 50. The process of controlling the temperature of the heating element 40 so as to be the surface temperature input to the controller 70 is performed.

Laminating system 10 according to the present embodiment is characterized in that the process temperature is controlled by measuring the surface temperature of the cloth fabric 5, unlike attaching a temperature sensor in the frame 20 is conventionally supplied with heat. The formation of the composite fabric 5 using the hot melt adhesive film 2 substantially acts most sensitively to the external environment, in particular to temperature. For example, when a certain amount of heat is supplied to an object having a unit volume of 10 cm 2 and the same temperature and time are applied to an object having a unit area of 100 cm 2, the temperature rise will be different. In the latter case, there is a way to increase the temperature of the resulting object, but to supply higher heat or to increase the time, but the exact temperature rise and time cannot be predicted. On the contrary, the present invention measures the surface temperature of the fabric fabric 5 in real time, and in order to maintain a constant temperature based on the measured temperature, the work speed is primarily reduced to maintain a constant temperature and increase the temperature while increasing the temperature. By increasing the workability will be increased.

As described above, the laminating system and the temperature control method for adhering the hot melt adhesive film according to the preferred embodiment of the present invention to the fabric is shown in accordance with the above description and drawings, but this is only described for example and the present invention Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention.
