Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhesive press device that heats and bonds an interlining material having a thermoplastic material to a woven fabric material, and more particularly to an adhesive press device that uses heating by a high-pressure steam circulating heater or an electric heater.

[0002]

[Prior art]

 Conventionally, the interlining is bonded to the woven fabric material by a high-frequency thermocompression bonding device in which it is bonded all at once by a high-frequency current, or an electrothermal bonding press device that heats with an electric heater or a high-pressure steam circulation heater and presses with a pressing roller. The method according to.

For heating by an electric heater, a nichrome wire heater mounted on a plurality of heating elements arranged in parallel is connected to a control circuit to form a control system.

The heating of high-pressure steam by a circulating heater has been recently developed, and a stainless steel tube, an iron tube, or a stainless steel tube is fitted into a heater case formed of a stainless steel plate, an iron plate, or an aluminum plate to form a heating body. A heating system is used in which heating elements are arranged in parallel and the ends of the fitted tubes are connected to each other to form a circulation system.

[0005]

[Problems to be solved by the device]

 The heating body of the thermocompression bonding heater in the conventional adhesive press machine is made of iron or stainless steel to form the heater case by plate processing, so special consideration for rust prevention and weight is required, and the processing cost is also high. It has become.

Further, a gap is created between the heater case and the fitted heat source, which is disadvantageous in terms of heat efficiency and structurally unstable.

Further, the high-pressure steam circulation heater and the electric heater have their respective characteristics with respect to the heating temperature, temperature unevenness, etc., and effective bonding can be performed by proper use, but with the current press equipment, There is a problem that both cannot be installed.

[0008]

[Means for solving problems]

 The present invention addresses the above-mentioned problems, is lightweight, has high thermal efficiency, is advantageous in terms of manufacturing and processing, and aims to provide an adhesive press device capable of switching between high-pressure steam and electric heat as needed. It was done.

That is, the structure of the heating elements arranged in parallel on the conveyor belt is basically a structure in which a copper tube for passing high-pressure steam is embedded in the heater case formed by drawing and casting an aluminum casting with the peripheral surface closely attached. The purpose was achieved by embedding an electrothermal heater in the heater case if necessary.

[0010]

[Action]

 The product fed between the conveyor belts 3a and 3b suspended on the driven roller is conveyed while being heated by passing between the heating bodies 61 to 66 arranged in parallel while being pressed by the belt. Then, it is pressed against the pressing rollers 2a and 2b at the transport outlet 31 to be finished.

The heater case 6a, which constitutes the heating element, has a solid shape in which an aluminum casting is drawn and formed, and a copper tube 6b through which high-pressure steam is passed, or an electric heater 6c is embedded in parallel with the copper tube so that its peripheral surface is in close contact. Therefore, the thermal effects of high-pressure steam and electric heat that pass through the copper pipe are directly transmitted to the heater case, and the thermal efficiency is improved.

The temperature sensor 71, which is set at a predetermined position of the heater case 6a that constitutes the heating element, issues a signal when the heating element is above a certain temperature or below a certain temperature. The heat source is opened and closed to adjust the temperature.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1a and 1b are a pair of upper and lower driven rollers that are rotatably supported with a gap for feeding the cloth and the interlining, and a conveyor belt 3a3b that hangs and conveys the adhesive cloth A that overlaps the cloth and the interlining. To do.

Reference numerals 2a and 2b denote a pair of upper and lower pressing rollers that hang the conveyor belts 3a and 3b corresponding to the driven rollers and press the cloth and the interlining at the conveyor outlet.

Reference numerals 4a and 4b denote small diameter auxiliary rollers erected freely in front of the pressing roller. 4b is slightly below the upper end of the lower pressing roller 2a, and 4a is slightly below the lower end of the upper pressing roller 2b. It is located above.

Numerals 5a and 5b are tension rollers for adjusting the tension of the conveyor belts 3a and 3b, and the above is the structure of a general conveyor mechanism of the interlining adhesive pressing apparatus.

Numerals 61 to 66 are heating elements which are alternately arranged above and below the conveyor belts 3a and 3b to heat the product in parallel, and a copper pipe through which high-pressure steam is passed through a solid heater case 6a formed by drawing an aluminum casting. 6b, or an electric heater 6c is loaded in parallel with the copper tube.

In the heater case 6a, an aluminum casting is drawn out into a shape in which the loading hole 6d of the copper tube 6b is formed, the copper tube 6b is inserted into the loading hole, and the bottom diameter of the copper tube 6b is smaller than the inner diameter of the copper tube 6b. Inserting a slightly larger conical core and pulling it from one end of the copper pipe to the other end to expand the diameter of the copper pipe, the outer peripheral surface of the copper pipe will become the inner peripheral surface of the loading hole 6d of the heater case 6a. To be in close contact.

In this way, the ends of the copper pipes 6b embedded in the heater case 6a are sequentially connected to form the high-pressure steam circulation system 6.

The formed circulation system 6 is provided with a temperature sensor 71 at an appropriate location, and stores or discharges high-pressure steam that is pressure-fed through a steam pipe 8 equipped with a solenoid valve 7 connected to the temperature sensor 71, or heats it. Adjust the heating temperature of the body. A steam trap 9 collects and discharges water droplets generated from steam.

Further, the aluminum casting is drawn out in a shape in which the copper tube loading hole 6d of the heater case 6a is formed on both sides and the loading hole 6e of the electrothermal heater 6c is formed in the central portion, and the electrothermal heater 6c is embedded in the central portion of the heater case 6a. , The copper pipes 6b are embedded on both sides, the ends of the copper pipes are connected in series to form a circulation control system for high-pressure steam, and the end of the electric heater 6c embedded in the central part is connected to the electric control circuit. It will be more functional if the high-pressure steam heating and the electric heater heating can be used selectively or competitively.

[0022]

[Effect of device]

 The combination of the aluminum casting formed by drawing and the embedded copper pipe has made it possible to provide an interlining bonding press device with a compact heating element that is lightweight and has good heat conduction, which was not possible with conventional heating elements.

Rust does not occur due to the materials such as aluminum and copper, the manufacturing process is shortened by drawing, and the structure is stable by embedding, which makes it easy to handle.

Further, since high-pressure steam capable of controlling temperature by pressure control and simple electric power can be selectively used, there is an effect that a wide range of heating demand can be met.
