Such embodiments are provided by way of example so that those skilled in the art can understand the specific contents for carrying out the invention can be modified in many different forms, the scope of the present invention is It is not limited by the following example.

(Example 1)

This embodiment relates to a surface coating apparatus 100 using a film that is continuously fed and removed, as shown in FIG. 1 by way of example.

The surface coating apparatus 100 using the film continuously supplied and removed which concerns on a present Example is provided with the conveyance part 110, the film 120, and the film control part 130. As shown in FIG. In addition, the coating apparatus 100 of the present embodiment may further include a curing apparatus 140 and a material supply unit 150.

The coating device 100 is an apparatus which coats the surface using the film continuously supplied to and removed from the coating material 11 arranged on the surface of the raw material 10.

The material 10 may be various objects as the object to be coated on the painting device 100. For example, the material 10 may be a plate such as a medium density fiberboard (MDF) or a particle board (PB). Both MDF and PB are sawdust or hard wood mixed with finely crushed wood and adhesive, and hardened by heat and pressure. They have the advantage of being able to be made in various forms because of their good workability, but they are easily deformed or crushed by water or moisture. . MDF has a high strength because the particles are small and tightly bonded, while PB has a relatively low strength because the particles are large and have a weak bonding force. Since MDF or PB is vulnerable to water or moisture, it is necessary to surface-treat such as adhering a film or coating a coating to block water or moisture. The coating device 100 is a device for coating a coating on the material 10 such as MDF or PB.

The paint 11 is coated on the surface of the material 10 by the painting apparatus 100 and may be made of various materials. For example, the paint 11 is dried or cured by ultraviolet rays, a mixture of 53 to 94% by weight reactive oligomer, 5 to 40% by weight acrylic monomer crosslinking agent and 1 to 7% by weight photoinitiator, and a small amount of pigment and Other additives may be added. The paint 11 may preferably be a mixture of 70 to 82 wt% reactive oligomer, 15 to 25 wt% acrylic monomer, and 3 to 5 wt% photoinitiator, most preferably 76 to 80 wt% reactive The oligomer, 16-20 wt% acrylic monomer, and 4 wt% photoinitiator may be mixed. Here, the acrylic monomers include 2-HEA (2-Hydroxyethyl Acrylate), IBOA (Isobornyl Acrylate), DPHA (Dipentaerythritol Hexylacrylate), TMPTA (Trimethylopropane Triacrylate), HDDA (1.6 Hexanediol Diacrylate), PETA (Pentaerythritol Triacrylate) and TPGDA (TPGDA) Tripropyleneglycol Diacrylate) may be any one monomer selected from the group consisting of or a mixture of one or more monomers. The photoinitiator may be used by dissolving a powdery initiator in an organic solvent such as Acetone, Methylene Cloride, and Ethyl Acetate at a concentration of 30 to 50%. In addition, the paint 11 may be blended with 1 to 25 parts by weight of colored pigments and 1 to 2 parts by weight of additives according to color with respect to 100 parts by weight of the mixture.

The transfer unit 110 continuously transfers the plurality of raw materials 10 having the paint 11 arranged on the surface thereof. Thereby, the film 120 is continuously supplied to the paint 11 arranged on the surface of the plurality of materials 10 while continuously conveying the plurality of materials 10 arranged on the surface of the paint 11. The coating 11 can be continuously covered and continuously pressurized to continuously flatten the coating 11, and the film 120 can be continuously removed from the flattening coating 11. Therefore, the conveying unit 110 may cover the paint with the film only by raising the support and the lifting unit on which the material is arranged on the surface to the place where the film fixed to the frame is located. The film covering the paint must be crimped to flatten the paint and then lower the support and the lift to remove the film from the paint, until the end of the process to support and lift the other material with the paint arranged on the surface. Compared to the conventional coating apparatus that cannot be lifted by the negative part, it is possible to supply the film to the paint arranged on the surface of the material, to cover and press the film, and to flatten the paint very quickly and accurately, as well as the film from the flattened paint. Can be removed very quickly and accurately.

The transfer unit 110 may be formed in various configurations that can be continuously transferred while supporting the plurality of materials 10 having the paint 11 arranged on the surface thereof. For example, the transfer part 110 may include a support part 111 for supporting a plurality of materials 10 having the paint 11 arranged on a surface thereof, and a driving part 112 for driving the support part 111 continuously. Can be. Here, the support 111 is composed of a pair of chains, the drive unit 112 is composed of a drive sprocket that is rotated by a motor to move each chain indefinitely orbits and driven sprockets that are linked to the drive sprocket through the chain. Can be. In addition, the support part 111 may be made of a conveyor, and the driving part 112 may be made of a device that is rotated by a motor to move in an infinite orbit of the conveyor.

The transfer unit 110 is arranged such that the support 111 and the driving unit 112 correspond to each one of the raw materials 10 one by one to quickly transfer one raw material 10. However, the transfer unit 110 is not limited thereto, and the support unit 111 and the driving unit 112 are arranged to correspond to each of the plurality of materials 10, for example, two materials 10, so that two materials ( 10) can also be transported continuously. In addition, the transfer unit 110 may be arranged such that the support 111 and the drive unit 112 correspond to each of the plurality of raw materials 10 so as to continuously transport the plurality of raw materials 10 for a longer time.

The film 120 is continuously supplied to the paint 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the conveyer 110. As a result, the paint 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the transfer unit 110 can be continuously covered and pressurized continuously to flatten the paint 11.

The film 120 may be formed of various materials capable of flattening the paint 11 by continuously covering the paint 11 arranged on the surface of the material 10 and simultaneously pressing the paint 11 continuously. For example, the film may be a polyethylene terephthalate (PET) film. When the paint 11 is dried or cured by heat, it is preferable to apply heat to the paint through the film 120 while the paint 11 is covered by the film 120, so that the film 120 is heat resistant. It is preferable to include a material. When the paint 11 is dried or cured by ultraviolet rays, it is preferable to irradiate the paint with ultraviolet rays through the film 120 in a state in which the paint 11 is covered by the film 120. Silver preferably includes a material that transmits ultraviolet rays, and preferably includes a heat resistant material.

The film control unit 130 continuously covers the paint 11 with the film 120 continuously supplied to the paint 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the transfer unit 110. At the same time, the pressure is continuously applied to flatten the paint 11, and the film 120 is continuously removed from the flattened paint 11.

This simplifies the process of planarizing the paint 11 by continuously covering the paint 11 and continuously pressing the paint 11 disposed on the material 10 using the film 120 supplied continuously. By greatly shortening the time required for the flattening process of the paint 11, the process of removing the film 120 from the flattened paint 11 by continuously removing the film 120 from the flattened paint 11. By greatly reducing the time required for the work, it is possible to drastically reduce the amount of work of the worker and to significantly improve productivity.

The film controller 130 continuously covers the paint 11 with the film 120 continuously supplied to the paint 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the transfer unit 110. At the same time, it can be made of various configurations that continuously pressurized to flatten the paint 11 and continuously remove the film 120 from the flattened paint 11. For example, the film controller 130 may include a first film control roller 131 and a second film control roller 132.

The first film control roller 131 continuously feeds the paint 11 into the film 120 continuously supplied to the paint 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the conveyer 110. The cover 11 is pressurized and continuously pressurized to flatten the paint 11. The first film control roller 131 may be in close contact with the paint 11 so that the film 120 continuously supplied to the paint 11 arranged on the surface of the plurality of materials 10 continuously conveyed by the conveying unit 110. It may be to pressurize.

To this end, the first film control roller 131 may be formed in various configurations. For example, the first film control roller 131 may be rotated in the forward direction so as to correspond to the conveying direction of the plurality of materials 10 continuously conveyed by the conveying unit 110. In addition, the first film control roller 131 continuously covers the paints 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the conveying unit 110 and simultaneously presses them continuously to flatten the paints. To be spaced apart from the surface of the paint 11 so as to be spaced apart by, for example, a thickness smaller than the thickness of the film 120. Furthermore, the first film control roller 131 may extend along its rotation axis to a length equal to or greater than a width in a direction perpendicular to the conveying direction of the plurality of materials 10 continuously conveyed by the conveying unit 110. have. The first film control roller 131 easily covers the paints 11 arranged on the surfaces of the plurality of materials 10 continuously conveyed by the conveying unit 110, and simultaneously presses them continuously to flatten the paints. It is desirable to have sufficient weight to do so. Since the position of the first film control roller 131 can be kept constant without being changed, the first film control roller 131 is relatively simple in configuration compared to a conventional compression roller whose position is changed, so that the driving is quickly and accurately maintained. And the weight is greatly increased, which can greatly increase the pressurization efficiency.

The second film control roller 132 continuously removes the film 120 from the paint 11 on the surface of the material 10 flattened by the first film control roller 131.

To this end, the second film control roller 132 may be formed in various configurations. For example, the second film control roller 132 may be rotated in the forward direction so that the paint 11 corresponds to the conveying direction of the flattened material 10 by the first film control roller 131. In addition, the second film control roller 132 is a first film control roller to continuously remove the film 120 from the paint 11 on the surface of the material 10 flattened by the first film control roller 131. It may be arranged at a distance away from 131, for example, at least as far as the length of the conveyance direction of the workpiece 10. If the first film control roller 131 includes a curing device 140 for curing the paint 11 by irradiating light on the film 120 in contact with the paint 11 on the surface of the flattened material 10 If desired, the film 120 is preferably removed after the paint 11 is cured, so that the second film control roller 132 is positioned opposite the first film control roller 131 relative to the curing device 140. It is desirable to. Furthermore, the second film control roller 132 may extend along the axis of rotation with a length equal to or greater than the width in the direction perpendicular to the conveying direction of the plurality of materials 10 continuously conveyed by the conveying unit 110. have. The second film control roller 132 has a light weight sufficient to easily and continuously remove the film 120 from the paint 11 on the surface of the material 10 flattened by the first film control roller 131. desirable. The second film control roller 132 does not simultaneously remove the film 120 from the paint 11 on the surface of the flattened material 10 as a whole, but instead of removing the film 120 from the paint 11 on the surface of the flattened material 10. Partial separation from the side that meets the film control roller 132 to the opposite side in turn removes the film 120 from the paint 11 on the surface of the flattened material 10, thereby simultaneously removing the film 120 as a whole. The simple configuration allows the drive to be maintained quickly and accurately, and greatly prevents a part of the surface of the paint 11 from sticking and falling off during the film removal process, so that the surface of the paint 11 from which the film 120 has been removed is greatly smoothed. Can be maintained.

In addition, the film control unit 130 continuously discharges the wound film 120 and supplies continuously to the paint 11 arranged on the surface of the plurality of materials 10 continuously conveyed by the transfer unit 110. The film control roller 133 may further include. The third film control roller 133 may include an unwinding roller 133a and a supply guide roller 133b.

To guide the roller. The feed guide roller 133b is accurately and smoothly placed on the paint 11 arranged on the surface of the plurality of materials 10 continuously conveyed by the transfer unit 110 to the film 120 discharged from the unwinding roller 133a. It is preferable that it consists of a plurality of rollers so that it can be continuously supplied.
