とする多色塗装装置。 Each color paint is supplied under pressure from a paint supply source to each double-acting reciprocating pump 3a, 3b through paint supply piping 2a, 2b, and is supplied under pressure from a working fluid supply source 4 to each reciprocating pump 3a, 3b through a working fluid supply piping. The paint of the specific color selected by switching the color change valves 7a, 7b is supplied to each color change valve 7a, 7b at a predetermined flow rate corresponding to the flow rate of the working fluid applied to the paint. In the multi-color coating device, each of the reciprocating pumps 3a, 3b is connected to a working fluid supply source 4.
A first working fluid supply pipe 5 is provided with a metering rotary pump 11 that pumps working fluid at a flow rate corresponding to the paint discharge amount of the paint sprayer 10, and an operation for circulating paint that is not supplied to the paint sprayer 10. Directional control valves 9a, 9 are connected to the second working fluid supply pipe 6, which is provided with a circulation rotary pump 13 that pumps fluid.
The pipes 15a, 15b, which are switchably connected to each other via the pipes b, and which connect the respective directional control valves 9a, 9b and the second working fluid supply pipe 6, have been cleaned of the previous color paint. Reciprocating pumps 3a and 3b for filling the next color paint into the coating machine 10
Flow rate adjustment valves 16a and 16b are provided to increase the flow rate of the working fluid supplied to the paint circulation.
In addition, the flow rate of the next color paint supplied to the reciprocating pumps 3a, 3b which fill the next color paint into the coating machine 10 is also set in each of the paint supply pipes 2a, 2b during painting and during paint circulation. A multicolor coating device characterized by being provided with flow rate regulating valves 17a and 17b that increase the flow rate.
