PROBLEM TO BE SOLVED: To provide a coating feeding system capable of varying a reciprocation amount of the coating in a branch passage connected with a coating gun and reducing a mounting capacity of a coating robot. SOLUTION: A mixed coating made by mixing a solvent with the coating is fed to a coating flow passage 1. One end 2f of the branch passage 2 is connected to the coating flow passage 1 and the coating gun 3 is connected to the midway of a route reaching from one end 2f to the other end 2s. A pig 4 air-tightly closes the inside of the branch passage 2 and is stored movably in the branch passage 2. An action of feeding a fluid F from the other end 2s side of the branch passage 2 to move the pig 4 to move the mixed coating to one end 2f side of the branch passage 2 and an action of feeding the mixed coating from one end 2f side of the branch passage 2 to move the pig 4 to the other end 2s side of the branch passage 2 are alternately repeated to reciprocate the mixed coating in the passage 2. The movement amount of the pig 4 is varied by varying the flow rate of the fluid F. COPYRIGHT: (C)2007,JPO&INPIT
