装置。 A paint circulation circuit 8 that supplies paint from a paint tank 7 via a pump 11 to color change valves 4a to 4c connected to the painting gun 2, and a return path closing valve 14 and paint discharge from the color change valves 4a to 4c. a paint return circuit 13 connected to a position upstream of the pump 11 of the paint circulation circuit 8 via a paint valve 16; In order to open and close the cleaning valve 5 connected to the painting gun 2, the cleaning valve 5 and the pressure air source 37 are connected to each other via a first switching valve 23. and a second air supply path 38 connected via a valve 39, which operates in conjunction with the first switching valve 23 when the first switching valve 23 is opened to open the color change valves 4a to 4c. The paint return circuit 13 is activated by operating the return path closing valve 14.
When the cleaning valve 5 is opened by closing the second switching valve 39, the paint discharge valve 16 is operated in conjunction with the second switching valve 39 to eliminate the paint return circuit 13. A paint circulation device characterized in that it is configured to communicate with a paint tank 15.
