BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for painting a surface of a panel made of wood or synthetic resin, etc., which is used for home or office showcases, bookcases, bookshelves or various sinks or work benches, and more specifically, paint or ultraviolet paint. A paint storage unit for storing various paints such as (UV paint) or urethane paint, a paint supply unit for supplying the paint storage unit with a predetermined amount of paint to a painting roller unit provided at an upper portion thereof, and a paint supplied from the paint supply unit A coating roller part which is applied to the outer circumferential surface of the rotating roller to be rotated to a certain thickness while controlling the coating amount of the coating material to be applied to the surface of the panel to be supplied to a desired thickness, and the upper part of the painting roller part Amount to finely control the amount of paint supplied to the outer circumferential surface of the painting roller by lifting and lowering Relates to an apparatus and method for coating panel, it characterized in that it is composed of a hip.

Generally, panels used for home or office showcases, bookcases, bookshelves or various sinks or work benches are made of panels of a certain size by processing synthetic resin panels, medium density fiberboard (MDF) or synthetic wood or natural wood. The panel manufactured to a certain size as described above is polished the surface (front, back and outer circumferential surface) and then coated with various paints such as paint, UV paint (UV paint) or urethane paint (primary coating), Through the painting process such as middle painting (secondary painting) and top coat (third painting), the appearance is enhanced by gloss formation and strength reinforcement and durability is improved. Currently, the surface painting work of the panel is mechanized. It is processed by an automated process through the advanced device to quickly paint a large amount of panels.

Conventional panel coating apparatus (1 ') is provided with a paint storage chamber (3') for storing a variety of paint therein as shown in Figure 11 and the coating roller of the cylindrical shape on the top of the paint storage chamber (3 ') (34 ') and the contact roller 67' abuts on one side of the painting roller 34 'receives rotational force from a normal driving motor (not shown) to rotate in opposite directions. A paint spray hose 68 'is provided from the suction pump 71' inside the paint storage chamber 3 'and a spray nozzle 70' is mounted at the end of the suction pump 71 '. A hose 69 'is provided and the spray nozzle 70' of the paint spray hose 69 'is located close to the upper boundary where the painting roller 34' and the contact roller 67 'are in contact with each other. The paint from the paint storage chamber 3 'is transferred through the spray nozzle 70' of the paint spray hose 69 '. The coating roller 34 'by the contact roller 67' rotated in the opposite direction of the painting roller 34 'while being injected and flowed down between the boundary of the painting roller 34' and the adhesion roller 67 '. Is applied to the outer circumferential surface of the coating roller 34 'and the other side of the panel P', which is transported along a conventional conveyor or rail, is in contact with each other so that paint is coated on the surface of the panel P '. have.

However, in the conventional panel coating apparatus 1 'as described above, the paint is sprayed only between the paint roller 34' and the upper boundary portion of the contact roller 67 'so that the paint is coated roller 34'. It is not evenly applied to the entire outer circumferential surface of the paint and the amount of paint flowing along the boundary between the paint roller 34 'and the contact roller 67' is not constant, so that the paint has a constant thickness on the outer circumferential surface of the paint roller 34 '. Therefore, there is a problem that the surface of the panel (P ') is unevenly coated (塗裝) is not applied, the paint sprayed through the spray nozzle 70' splashes in all directions or outside the coating device (1 '). Sanaa working environment is very dirty and not clean, and the paint simply flows down and is applied to the painting roller 34 ', so it is not possible to finely control the supply amount of the paint and the painting roller for smooth flow and application of the paint. 34 'long loom When the surface or the edge of the panel P 'is rounded or inclined at a predetermined angle, it cannot be applied to the conventional coating device 1' because it is formed only in a cylindrical shape of a mold. There was a problem.

The present invention is to solve the above problems, the paint is evenly applied to the entire outer circumferential surface of the painting roller to a certain thickness so that the surface of the panel to be in contact with the outer circumferential surface of the painting roller smoothly painted, the supply of the paint is made smoothly Finely control the coating amount and supply amount of paint while making it, so that the operator can make the painting work to the desired thickness, and the paint flowed along the painting roller while preventing the paint from splashing out or leaking to the outside of the painting device. Through the ball, it is recovered and reused to the paint storage room so that clean and clean work can be done, and the painting roller and coating amount control plate are made in various shapes so that they can be easily attached and detached and assembled. Is to make it form have.
