Abstract

In an apparatus for supplying powder coating material, when a given supply rate Qm of powder coating material F and a carrier air flow rate Qt are inputted, whether learned data of a suction air pressure Pfm with respect to the inputted given supply rate Qm is stored in a memory or not is determined. If the data is stored, the learned data of the suction air pressure Pfm is read, and a pressure regulator for suction air is instantaneously operated to be adjusted to have the value of the read learned data. After that, the apparatus moves to PID control with the given supply rate Qm being the target value. The value of the suction air pressure Pfm when the actual supply rate equals the given supply rate Qm is stored in the memory as learned data.
