(B) A reference coating surface contact member consisting of a number of sliders, rotors, etc.

(C) The knife coater is screwed into and out of the tip of the knife coater so as to be adjustable in and out.

This is a coating thickness adjusting device in a plate material putty repair machine.

[0010]

The coating thickness adjusting device in the plate material putty repair machine according to the present invention can be used to carry out the process of filling the concave portion of the plate material using the putty agent for filling the concave portion from the work of filling the concave portion of the plate material using the putty agent for surface coating. It can be applied mutatis mutandis to repair work.Especially, various kinds of synthetics are used when applying a putty agent to a plate material such as particle board with a knife coater and painting the entire surface of the plate surface with the same thickness to repair it. The coating operation of the surface coating method, in which a putty for surface coating consisting of a mixture of a resin and various additives, etc. is applied to the entire surface of the plate surface with a knife coater in the same thickness and ironing, is performed as follows. is there.

That is, when a putty agent for surface coating consisting of an admixture of various synthetic resins and various additives is applied to a plate material plate surface using a coating thickness adjusting device in the plate material putty repair machine of the present invention. Work is performed on a plate material such as a particle board in the process of transporting a reference application surface contact member such as a slider or a rotor screwed inside the knife coater, that is, on the side where the putty agent for surface coating stays. While being slidably or rotatably abutting the surface, the knife coater is pressed obliquely from above by a pressing member such as an air cylinder toward the plate surface of the plate material, and at that time, the tip of the knife coater In order to form a desired gap by adjusting the screw of the threaded portion between the plate material plate surface of the particle board and the like in the transport process, such that a gap of about 0.1 mm is formed, for example.
By adjusting the reference application surface contact member back and forth, the putty for the surface coating that is squeezed out from the gap to the carry-out side is applied by being raised to approximately 0.3 mm, Since the entire area of the surface can be coated with the putty for the surface coating to an equal thickness, the putty for the surface coating is transferred to a hot air dryer or the like in the next step to transfer the putty for the surface coating. By solidifying, transferring this to the next process and polishing the surface with a sander etc.,
Modification and repair of a material such as a particle board, which is not so good in secondary processing cosmetics due to material unevenness or adsorption unevenness, etc., could be performed by a coating operation using a surface coating method using this putty repair machine.

When the coating thickness adjusting device in the plate material putty repair machine of the present invention is used for a putty repair device for filling and repairing cracks in the plate surface of plywood or the like and concave portions such as insect holes, the above-described reference coating method is used. By lowering the surface contact member sufficiently rearward, the tip of the knife coater comes into close contact with the plate material plate surface, and the recess filling and repairing work can be performed by desired ironing in which only the recess is filled with the staying putty agent. Needless to say, such adjustment is made.

The putty agent 4 is replenished onto the plate 2 by the vessel 3, and the amount of the replenishment is adjusted by a photoelectric distance sensor 5 or the like, and is conveyed by a knife coater 7 which is diagonally installed on a surface plate 6 which supports the plate material 2. The putty agent 4 replenished on the plate material 2 in the process is applied by ironing to fill and repair recesses such as cracks and insect holes on the plate surface, or to modify and repair the entire surface of the plate surface by painting it to an equal thickness. This is a coating thickness adjusting device in a plate material putty repairing machine configured to perform coating.

That is, the coating thickness adjusting device in the plate material putty repairing machine of the present invention uses a knife coater 7 directed obliquely from above to the plate surface of the plate material 2 via a pressing bar 9 by a pressing member 8 such as an air cylinder. In addition to being obliquely arranged to be able to press freely, inside the knife coater 7, that is, on the side where the putty agent 4 stays,
A reference coating surface contact member 10 composed of a number of sliders (shown), a rotor and the like is adjusted with the knife coater 7 by adjusting screws 11.
It is configured to be screwed into and out of the front end portion so as to be adjustable in and out.

Accordingly, the reference coating surface contact member 10 is in contact with the plate surface of the plate member 2 and slides or rotates while the tip end of the knife coater 7 and the plate member 2 A desired gap G is formed between them, so that the plate surface of the plate material 2 on the carry-out side can be modified and repaired by applying a putty having a desired thickness to a uniform thickness over the entire area.
Of course, if the reference coating surface contact member 10 is lowered sufficiently rearward, the gap G becomes zero, so that the putty agent other than the filling portion of the concave portion is scraped flat, and the filling repair work for the concave portion of the plate surface can be optionally performed. It can be implemented.
