の除去とストリパッブル塗料の乾燥工程が必要となる。When a curtain flow system is used for continuous coating while transporting it on a conveyor, the paint or the like tends to come around from the front surface of the plate-shaped object to be adhered to the back side. For this reason, a masking film had to be stuck on the back side of the object to be coated, and after the coating film was cured, the masking film had to be peeled off to remove the coating film attached to the back side of the object to be coated. However, this method requires the steps of attaching and removing the masking film. For this reason, JP-A-61-212362 proposes to omit the film sticking step by applying a strippable paint. However, even in this case, it is necessary to remove the stripable coating and dry the stripable coating.

を搬送させることを特徴とする拭き取り方法である。The present invention relates to a curtain flow type coating method, in which a plate-shaped object to be coated is made to fly in a curtain of paint or the like, and is a porous material that gently moves in the opposite direction to the flight direction. Land on the belt conveyor consisting of the body,
Further, while sliding on the belt conveyor by the inertial force of flight, while the coating material or the like adhered to the back surface of the object to be coated is wiped off by touch, the object to be coated is transported while being wiped off. This is the wiping method.

連続的に塗装するシステムにはカーテンフロー方式が広

付近では余分に塗料等が付着し、この過剰量の塗料等が
被塗装体の裏側に廻り込む現象が発生する。A curtain flow system is widely used for a system for continuously applying a plate-shaped object to be coated while conveying it by a conveyor. In this system, extra paint or the like is applied near the front part of the object to be coated, that is, near the head. Occurs, and a phenomenon occurs in which this excessive amount of paint or the like wraps around the back side of the object to be coated.

ができる。According to the method of the present invention, an article to be coated, which has just flown through the curtain of paint and has just been applied, is landed on a belt conveyor of a porous body which moves in the direction opposite to the flight direction, so that an undried coating film is formed. While wet with the conveyor surface, slide in the flight direction by the inertial force of flight in the flight direction, before the coating film is dry and hardened, that is, before the coating film is touch-dried, while wiping off the coating material on the back surface, and It can be conveyed on the conveyor of the process.

からである。The speed of the porous body in the direction opposite to the flight direction of the belt conveyor must be determined in consideration of the flight speed, shape and weight of the object to be coated. This is because the inertial force in the conveying direction of the object to be coated and the sliding frictional force with the conveyor surface are affected by these factors. However, the speed in the opposite direction should not be increased to such an extent that the article to be coated slips and hinders the conveyance onto the conveyor in the next step. Furthermore, if the belt conveyor is set in the opposite direction to the flight direction, the landing place of the object to be coated will always be the belt conveyor surface of a clean porous body, and the effect of scraping off paint etc. adhering to the back surface will be improved. This is because the wiping effect can be enhanced.

い。Since the conveyor of the present invention needs to be wet with the paint on the back side as described above, the material of the conveyor is a material that easily wets the paint and has an absorbing effect, that is, paper, cloth, non-woven fabric or the like. Porous bodies are particularly preferred. The conveyor belt itself may be made of these materials, but it may also be a composite material in which the above-mentioned porous body is adhered to the surface of a material such as rubber in order to enhance the toughness of the belt.
