ので、環境問題の点からも近年注目されている。2. Description of the Related Art Powder coating has attracted attention in recent years also from the viewpoint of environmental problems because it does not contain an organic solvent and can recover and reuse overspray powder of powder coating.

るようにしている。[0003] In this powder coating, an object to be coated suspended from above is conveyed into a coating booth by a conveyor, and a static electricity is applied to the object to be conveyed into the coating booth by an electrostatic coating gun. Generally, a method of spraying a body paint, electrostatically attaching the powder paint to the object to be coated, and baking the powder paint applied in a baking furnace onto the object to be coated is common. In this powder coating, the overspray powder that has not adhered to the object to be coated in the coating booth is collected by suction and reused.

させている。Generally, in powder coating, an electrostatic coating gun is inserted from a side wall of a coating booth, and the powder coating is sprayed toward an object passing through the coating booth. Thus, the powder coating is attached to the object by static electricity.

を生じ易い。[0005] However, the shape of the object to be coated is diverse, and even if the flat portion of the object to be applied to the electrostatic coating gun can be relatively easily coated, the outer surface of the object to be coated has complicated irregularities. In some cases, it is difficult to uniformly apply the powder coating to the object to be coated. In particular, when the coating area on the front and rear surfaces in the traveling direction of the object passing through the coating booth is large or when the shape is complicated, coating unevenness easily occurs on the front and rear surfaces in the traveling direction of the object to be coated. .

が行われている。Conventionally, as shown in FIG. 10, a painting booth 21 is provided with a first painting stage and a second painting stage along the traveling direction of the workpiece A, and the electrostatic painting of the first painting stage is performed. After the side surface of the object A is painted with the gun 22, the object A is rotated by 90 ° in the second painting stage, and the electrostatic painting gun 23 of the second painting stage is moved back and forth in the traveling direction of the object A. Is painted to make the coating film uniform.

First, since the first and second coating stages must be provided along the traveling direction of the article A, there is a problem that the total length of the coating booth 21 is increased and the installation space is increased. In addition, since the powder coating is excessively adhered to the portion coated in the first coating stage in the second coating stage, there is a problem that the film thickness is not constant or the coating surface is deteriorated.

A cartridge filter type suction / exhaust device 24 is installed on the side or bottom of the coating booth 21 so that overspray powder is sucked and collected from the side or bottom of the coating booth 21. FIG. 11 (a), (b) or FIG.
In (a) and (b), reference numeral 22 indicates an electrostatic coating gun. In FIGS. 12A and 12B, reference numeral 25 denotes a suction / exhaust port 25 on the bottom surface.

As shown in FIG. 13,
An electrostatic painting gun 22 is installed on the entrance side of the painting booth 21,
A suction / exhaust port 26 is provided on the outlet side of the coating booth 21, and a tunnel portion 27 whose wall surface is applied with a high voltage is provided between the electrostatic coating gun 22 and the outlet of the coating booth 21. When the object A passes through the portion 27,
There is also a method of making the overspray powder easily adhere to the object A to be coated. However, this method has a problem in that the flow of the overspray powder is in one direction in the same direction as that of the object A, so that the trailing direction behind the traveling direction is poor. In addition, when the ground or the like touches the wall surface of the tunnel portion 27 applied with the high voltage, the high voltage accumulated on the wall surface may flow rapidly and generate a spark.
