Problems solved by technology

[0016] Therefore, in each cleaning process, the unused conductive spraying material in the insulating pipe 2b is unnecessarily discharged, resulting in an increase in the amount of the conductive spraying material
In particular, if the electrostatic spraying process is performed for a long time, the amount of the conductive spraying material discharged from the insulating pipe 2b will remarkably increase, making the electrostatic spraying equipment very uneconomical

Abstract

An intermediate storage vessel (26) has a cylinder container (26a), a piston (28) provided in the cylinder container (26a) so as to be slidable in a reciprocating manner, and an inpour hole portion (32) and a discharge hole portion (34) that are opened in a cylinder chamber (30) where the piston (28) slides. The inpour hole portion (32) is provided above the discharge hole portion (34). An insulation cover (70) is provided so as to cover the intermediate storage vessel (26) and an insulation mechanism (20), and the cover is removable from the insulation mechanism (20) side.

Description

Technical field [0001] The present invention relates to a method and equipment for implementing electrostatic spraying by temporarily supplying a spraying material from a supply source to a spraying material container, and thereafter electrically insulating the supply source and the spraying material container from each other and supplying the spraying material to a spray gun to spray the material . Background technique [0002] For example, it is known that voltage blocking is a process for applying a high voltage to a conductive spray material to perform electrostatic spraying on objects to be sprayed such as automobile bodies. According to this process, the conductive spray material is temporarily introduced into an intermediate storage container (intermediate storage mechanism) insulated from ground potential, and then the supply path connecting the intermediate storage container and the spray material supply source is cleaned and dried, To form a voltage barrier. Then, the c...
