特公昭５１−４１１４１号に詳しく記載されている。2. Description of the Related Art Dead end systems, loop systems and third line systems are known as systems for supplying paint to a coating gun. In the dead-end type, as shown in FIG. 4 (a), a paint is supplied from a paint tank 20 to a pipe 22 whose final end is closed by a pump 21.
2, a branch pipe 23 is branched from a necessary portion, and a coating gun 24 is connected to the branch pipe 23. In the loop type, as shown in FIG. Branch pipe 2 from a necessary portion of circulation pipe 25 returning to tank 20
3 is branched, and a coating gun 24 is connected to the branch pipe 23. In the third line type, as shown in FIG.
A third pipe 2 extending this to return to the paint tank 20
6 so that the paint always circulates in the branch pipe 23 as well. Particularly, the third line type is described in detail in Japanese Patent Publication No. 51-41141.

ないので、材料の無駄が大きい。Among the above-mentioned conventional systems, in the dead-end system, the paint does not circulate in the pipe, so that the color changes between the beginning and the end of the coating or the metallic coating is applied. In such a case, aluminum particles in the paint may settle, and in the case of a two-part curable paint used by mixing a main agent and a curing agent, burrs may be formed on the surface of the paint. In the case of the loop type and the third line type, there is no disadvantage as described above. However, in these types, the pressure decreases as the final branch branch is farther from the pump, and coating unevenness easily occurs. As a means for solving this, it is conceivable to increase the pump capacity and increase the diameter of the pipe. However, the pot life of the two-part curable paint is 2-3 hours, and if the time is longer than that, the inside of the pipe will be reduced. Since paint must be discarded, material waste is large.
