Abstract

PURPOSE:To enable efficient dip painting by a simple method by placing a covering member having a cup shape on the non-painting section of a material to be painted of which the non-painting section is positioned at the top end and forming an air pocket in the covering member. CONSTITUTION:A material W to be painted is placed on a receiving table 1 fixed to the bottom end of a suspension means 2 in such a way that the non- painting section A thereof is positioned at the top end. A covering member 6 having a cup shape is placed on the section A and an air pocket 7 communicating with the outside is formed in the member 6. A vertical moving means mounted to the means 2 is then driven to descend the base 1 thereby dipping the material W together with the member 6 into a paint liquid L. The air in the air pocket 7 does not escape in this stage and therefore the paint is coated surely on the necessary section without intrusion of the liquid L into the air pocket.

る。FIG. 1 is a diagram showing a conventional coating method in which dip coating is performed while masking one end of the object W to be coated. In this method, a rubber ring 3 is blown onto one end of the object W to be coated, A cylindrical key 4 is fitted to the outside of the ring 3 so as to cover one end of the object W, thereby masking the non-coated portion A of the object W. After masking in this way, the object W to be coated is placed on the pedestal 1, and by operating the hanger 2 attached to the pedestal 1, the holder is placed inside the paint liquid stored in a container (not shown). The object W to be coated is soaked in water,
The coating is applied only to the coating range B of the object W to be coated.

Exhaust equipment must be installed due to the necessity of the work environment. Moreover, the work of peeling off the masking agent 5 is required, which impairs the efficiency of the painting work.
