Abstract

A coating liquid supply device that purifies a coating liquid that has been subjected to defoaming treatment in a plurality of coating liquid tanks by a filtering device, and guides the coating liquidfrom a liquid feeding device to a coating member. A communication path is arranged between the filtering device and the liquid feeding device and communicates with each of the coating liquid tanks, and the filtering device is replaced in a state where the coating liquid is stopped from being guided to the filtering device, and a vacuuming device is used to suck the replaced filtering device via the communication path and the coating liquid tank.

Description

technical field [0001] The invention relates to a coating liquid supply device. The coating liquid supply device guides the degassed coating liquid from a coating liquid tank to a filter device for purification, and guides the purified coating liquid to a delivery device. The liquid device is used to supply the coating components with the liquid delivery device. In particular, it is characterized in that the coating liquid that has been degassed by a plurality of coating liquid tanks is sequentially guided from the liquid storage tank to the filter device for purification, and the purified coating liquid is guided to the liquid delivery tank. device, when the liquid feeding device is used to supply the coating elements to carry out the coating sequentially, when the above-mentioned filter device becomes dirty, when the filter device is replaced, the air in the filter device after replacement can be properly removed, and can The above-mentioned painting operation is simply res...
