The present invention relates to a coating apparatus and a method for coating a carbon planar heating element, and more particularly, to a coating apparatus and a method for coating a carbon planar heating element for coating urethane film paper on both sides of the carbon planar heating element.

In general, the planar heating element is generated by the resistance of the applied power source is used in various fields such as electricity, flooring, instantaneous water heater.

The planar heating element has been developed in order to solve the problem of the heating element using a heating wire that the heat generation area is narrow because the heating wire cross-sectional area is narrow and the heat generation area is narrow.

Conventional carbon planar heating element is a heating element made of paper including a carbon print layer formed as carbon is printed on the surface, and is formed in a thin plate shape and provided on the heating element to at least two or more electrode bodies and a short circuit to convey polarity. In order to prevent safety accidents, such as electric shock, it is generally composed of an insulator coated on the surface.

The planar heating element forms a carbon printing layer by printing carbon on the surface of the heating element formed of paper material, and simply arranges the electrode body on the heating element, compresses and insulates the insulator on the surface of the heating element to press the electrode body. The body and the heating element are interviewed with each other so that they can be electrically connected.

However, the planar heating element as described above does not easily pressurize the electrode body because the insulator coated by stress such as repeated use and shape deformation is easily lifted, and thus there is a gap between the heating element and the electrode body, resulting in poor electrical contact. Not only can it be done, but also cracks may occur in the carbon print layer of the heating element which is not elastic, and electrical contact may be poor.

The planar heating element recently developed in order to solve the above problems is commonly referred to as a carbon planar heating element, and the carbon planar heating element is a woven fabric, and the heating element is dyed with carbon liquid, and both ends of the heating element and a carbon adhesive are interposed therebetween. It is a structure containing the electrode body of the copper foil or metal thin plate adhered through, and the insulator which coats the surface of the heat generating body to which this electrode body was attached.

The electrode body is attached to both ends and between the heating element through the carbon adhesive, respectively, such an electrode body is electrically connected to an external power source to transfer the +,-polarity of electricity to the heating element, and thus the heating element is electrically Heat is generated by the characteristic resistance.

The conventional carbon surface heating element of the prior art is coated (urethane) the surface of the urethane to prevent safety accidents such as electric shock due to a short circuit, such a urethane coating is frequently used even if used in mats, mattresses, car seats, etc. And because of its excellent elasticity and elastic restoring ability even after long use, it has the advantage of improving the reliability of the product without degrading the performance of the heating element.

However, the urethane coating on the fiber so far consists of a process in which a urethane raw material (urethane ball) is heated and melted in a hopper, and the molten urethane is applied to the surface of the fabric conveyed from the bottom of the hopper and then cooled. .

Therefore, in the conventional urethane coating of the woven carbon planar heating element, waste of urethane raw material due to the application of molten urethane is serious, the thickness of the coating layer is not constant, urethane is coated on the upper surface of the planar heating element Then, when the coated urethane is cooled after a certain time has elapsed, it has to perform a cumbersome process for coating the lower surface of the carbon heating element, the coating process has a long problem.

In addition, since the use of the planar heating element is mostly used in many contact and shape deformation, although the coated urethane layer and the planar heating element have to be strongly bonded, the coating is simply applied and cooled in the coating process and the cooling process. Because of this, when the above-described shape deformation is applied, a problem arises in that the planar heating element and the coating layer are lifted, thereby lowering the reliability of the product.

In addition, as shown in Figure 6, the carbon-like heating element (1) coated by the method of applying urethane is sold or used in units of a predetermined length, bar (A) coating the carbon-based heating element (1) as necessary length When cutting, as shown in FIG. 7, the heating element 1a and the electrode 1b are exposed on the cutting surface S, thereby causing a problem such as a short circuit.

In order to solve the above problems, a method of heating and compressing the urethane film by peeling from the method of applying urethane has been proposed in various ways, but the urethane is elongated when heated, and the melting point is 120 ℃ ~ 140 ℃ high temperature heating And there was a problem that pressurization is very difficult.

That is, when the urethane film paper is coated on the carbon plane heating element, the urethane film paper is pushed or coated due to the deviation of the surface area increased by heating and the temperature distribution of the heating element and the electrode body, or bubbles are generated, thereby increasing the defective rate. As a result, the productivity is seriously deteriorated, and there is no benefit due to the implementation, and thus it is impossible to implement.

The present invention devised to solve the above problems, by heating the urethane film paper at a temperature higher than the melting temperature of the urethane, relieve the temperature variation of the heating element and the electrode body, and prevents the surface change due to elongation of the urethane film paper In addition, it is an object of the present invention to provide a coating apparatus and a method for coating a carbon-type heating element that allows urethane film paper to be simultaneously heat-compressed on the upper and lower surfaces of the carbon-type heating element.

Here, the heating member may be composed of a heating coil (heating wire) (not shown) which is built in the drum of the first heating roller 111 and the second heating roller 112 to heat the drum (outer diameter surface). It can also be configured as a burner.

The heating member embedded in the drum as described above is as well known, the present invention is not limited to the heating coil described above can be applied to a variety of methods to configure the heating rollers (111, 112).

Therefore, the first heating rollers 111 are installed at predetermined positions between the upper and lower urethane rollers 101a and 101b and the upper and lower PET rollers 102a and 102b, and the second heating rollers are located at adjacent positions. Let 112 be installed.

Here, the first guide roller 109 is installed in close contact with the outer diameter surface of the first heating roller 111, the urethane film paper 103b of the lower urethane roller 101b and the PET film paper 104b of the lower PET roller 102b. After the guide is guided to the first guide roller 109, it is preferable to be rotated along the outer diameter surface of the first heating roller 111.

That is, the first guide roller 109 is in close contact with the outer diameter surface of the first heating roller 111 at a lower predetermined position of the first heating roller 111, the urethane guided to the first guide roller 109 The film paper 103b and the PET film paper 104b are rotated upward in a state of being wound around a predetermined area of the outer diameter surface of the first heating roller 111, thereby increasing the thermal conductivity, and thus the first heating roller 111. ), The urethane film paper 103b can be sufficiently heated.

On the other hand, the second heating roller 112 which is installed in a position adjacent to the first heating roller 111 is installed on the other side adjacent to, as shown in Figure 1, is installed to be in close contact with the first heating roller 111 As the urethane film paper 103b of the lower urethane roller 101b and the PET film paper 104b of the lower PET roller 102b are guided to the first guide roller 109, the second guide roller is in close contact with the second heating roller 112. By installing the roller 110, the urethane film paper 103a of the upper urethane roller 101a and the PET film paper 104a of the upper PET roller 102a are guided to the second guide roller 110 so that the second heating roller 112 is installed. It is wound in a certain area of the outer diameter surface of) and rotated downward.

Here, the PET film paper 104a (104b) of the upper, lower PET roller (102a, 102b) is in direct contact with the outer diameter surface of the second heating roller 112 and the first heating roller 111 can be directly heated The structure is guided to the second guide roller 110 and the first guide roller 109, the urethane film paper (103a, 103b) of the upper and lower urethane rollers (101a, 101b) is PET film paper 104a0 (104b) It can be seen that the overlap is guided to the second guide roller 110 and the first guide roller 109 is heated indirectly in contact with the outer diameter surface of the second heating roller 112 and the first heating roller 111. have.

That is, since the first heating roller 111 rotates and moves the urethane film paper 103b upward, and the second heating roller 112 rotates and moves the urethane film paper 103b downward, the first heating roller 111 and When the urethane film papers 103a and 103b heated by the second heating roller 112 are laminated with each other, upper and lower urethane film papers 103a and 103b are disposed at the center, and the PET film paper 104a is disposed thereon. 104b is disposed.

On the other hand, the upper urethane film paper that is heated by the second heating roller 112 is rotated downward by the second heating roller 112 to be installed in close contact with the pressure roller 106 as shown in the lower portion of the second heating roller (112). The lower urethane film paper 103b and the upper and lower PET film papers which are heated by the 103A and the upper PET film paper 104a and the first heating roller 111 and rotated upward and then transferred to the second heating roller 112. 104a and 104b may be press-welded while passing between the press roller 106 and the second heating roller 112.

Here, the upper surface of the urethane film paper 103b heated by the first heating roller 111 is supplied with a carbon surface heating element 105 cut to a unit length as shown in FIG. 1 by a predetermined supply means. By allowing the seat to be seated, the lower urethane film sheet 103b and the carbon planar heating element 105 are transported together so that the carbon planar heating element 105 is interposed between the upper urethane film sheet 103a heated by the second heating roller 112. To be deployed.

In the present invention, the supply means is not specified, and the operator may include placing the carbon surface heating element 105 cut to a predetermined length on the upper surface of the lower urethane film paper 103b conveyed from the second heating roller 112. Can be.

Therefore, the carbon planar heating element 105 is disposed between the upper and lower urethane film sheets 103a and 103b passing between the second heating roller 112 and the pressure roller 106, thereby providing the carbon planar heating element 105. The upper and lower urethane film (103a, 103b) will be able to be coated.

In particular, by installing the pressing roller 125 to be in close contact with the other outer diameter surface predetermined position of the pressing roller 106, by the second heating roller 112 and the pressing roller 106 by It is preferable to allow the urethane film paper fused by hot pressing to be rotated while being compressed while being wound in a predetermined region of the pressure roller 106 so that the fusion rate can be improved.

As described above, the urethane film paper in the present invention is heated by the first heating roller 111 and the second heating roller 112, the second heating roller 112, the pressure roller 106 and the compression roller 125 The upper and lower urethane film papers 103a and 103b are fused together by heat compression.

Melting point of the conventional urethane film paper (polyurethane) is 140 ℃, in general, when heated to more than 140 ℃ by a heating roller, as mentioned in the prior art, as the urethane film paper is stretched, the surface irregularly curved Even when pressed by the pressure roller 106 and the pressing roller 125, the fusion surface is uneven, such as bubbles enter or push to form wrinkles.

However, in the present invention, in heating the urethane film paper, the melting point of 225 ℃ ~ 265 ℃ PET film paper is directly heated in the first heating roller 111 and the second heating roller 112, the appropriate temperature at which the PET film paper does not stretch By heating up to, the urethane film papers 103a and 103b superimposed on PET film papers 104a and 104b are indirectly heated to a high temperature close to 140 ° C, and at this time, the urethane film papers 103a and 103b heated to high temperature. ) Is superimposed on PET film paper 104a (104b), which is only heated and has no surface change, so that its surface is prevented from being stretched, and is transported with PET films 104a and 104b while maintaining the original shape at the time of supply. It can be.

Therefore, the upper and lower urethane film papers 103a and 103b may be fused in contact with each other even when pressed in the process of passing through the second heating roller 112, the pressure roller 106, and the compression roller 125. Therefore, wrinkles do not occur on the fused surface, and bubbles may not be generated between the upper and lower urethane film sheets 103a and 103b.

In particular, since the urethane film papers 103a and 113b and the PET film papers 104a and 104b are heated to a high temperature, minute temperature deviations between the carbon planar heating element 105 and the electrode plate 105a attached to the carbon planar heating element 105 are observed. Since the upper and lower urethane film papers (103a, 103b) can not affect any of the fusion conditions, it is possible to completely eliminate the fusion or coating defect rate according to the temperature deviation.

On the other hand, PET film paper 104a, 104b passing through the first and second heating rollers 111 and 112, the pressure roller 106, and the compression roller 125 is the first and second heating rollers 111. The upper and lower urethane film papers 103a and 103b are not heated to the melting point of the PET film paper by the 112 and the second heating roller 112, even in the state where the upper and lower urethane film papers 103a and 103b are fused. PET film paper 104a, 104b can be maintained only in an overlapped state without being fused.

As described above, the urethane film paper fused by the pressure roller 106 and the compression roller 125, and the upper and lower PET film papers 104a and 104b, which are superimposed on the upper and lower surfaces of the urethane film paper, are pressurized rollers. It is installed adjacent to the 106 and the compression roller 125, the cooling member is cooled by being rotated while being partly wound around the built-in cooling roller 107.

Here, the cooling member is installed on the mounting stand or installed remotely from the mounting stand, and a cooling water circulation device (not shown) including a pump for feeding the cooling water and a supply pipe for transferring the cooling water to the cooling roller 107 and , May be composed of a plurality of cooling flow paths (not shown) formed in the drum of the cooling roller 107, and the cooling member can be used by adopting well-known public technologies as well as the heating member. This invention is not limited to this, It can variously adopt and change.

Meanwhile, the upper and lower PET film papers 104a and 104b cooled by the cooling roller 107 and the urethane film paper and the carbon surface heating element 105 fused therebetween are the upper and lower PET winding rollers 123b ( Separated from each other by the 123a and the heating element winding roller 124, the upper and lower PET winding rollers (123b, 123a) are installed on the other side of the cooling roller 107 by a predetermined distance away from the cooling roller 107. It is preferable to allow the microheat of PET film paper and urethane film paper via) to be completely cooled at room temperature.

 Therefore, the upper and lower PET film papers 104a and 104b to be transported are separated and wound on the upper and lower PET winding rollers 123b and 123a, and after the upper and lower PET film papers 104a and 104b are separated, The urethane film paper coated with the carbon surface heating element 105 is guided and wound up to the heating element winding roller 124.
