Abstract

PURPOSE:To uniformly apply paint onto the entire surface of a long workpiece to be coated having a complex sectional configuration, by providing a plate for controlling the steam of atomized paint around the workpiece to be coated, spraying the paint with spray gas, and then sucking the paint through a duct. CONSTITUTION:A plate 2 for controlling the steam of atomized paint having a configuration corresponding to the sectional configuration of a workpiece G to be coated and a space 2a through which the stream of atomized paint can flow between the plate 2 and the workpiece G to be coated is prvided in a coater C. By spraying paint through guns 4-8, it is applied onto the workpiece G to be coated. The excessive amount of the atomized paint is sucked through a suction duct on a suction floor. Thus, paint can be uniformly applied onto the entire surface of the workpiece even which has a complex configuration, and the coating work can be continuously performed with a high speed.

It corresponds to the shape and size of the body, and can be easily replaced.It passes through the coating device (IC) and is then applied to the airless coated object (Q).
The coated surface is dried by passing through the drying furnace p) by the μ transport device ut (g), and is sequentially sent to the finishing equipment +t and (F). In Fig. 1, (a) is a collection duct for the removed dust generated by the surface cleaning device;
(c) is the recovery tact for the gas generated during drying in the drying oven 0, (d) is the air duct that sends the hot air obtained from the combustion deodorizing oven 4 to the preheating oven (5), and (e) is the drying oven) Air duct h that sends hot air to (f)? It is an exhaust turret that discharges the used exhaust air from the preheating furnace 4 to the outside. Among these configurations, if the object to be coated has already been surface cleaned,
It goes without saying that the surface cleaning device (GB) is not necessary, and it is possible to easily implement a configuration in which the surface cleaning device is incorporated into the preheating MiJ.This invention In the coating device (C) which is the main part of
In the conventional method, the excess paint mist is immediately discharged;
The paint consumption yield was very poor, a large number of spray guns and airless guns were required, and uneven coating was likely to occur. , reflects the paint spray stream,
