Abstract: In a powder coating apparatus a pulse signal S2 of a low voltage generated by a pulse signal generation circuit (7) is boosted to a high voltage by means of a high voltage impression circuit (8), so that it is impressed upon corona electrodes (5). As a result, a corona discharge is intermittently generated from the corona electrodes (5) toward an object to be coated, whereby powder coating material sprayed from a nozzle opening of a gun main body in a forward direction is charged with negative ions developed by the corona discharge, whereafter it is directed toward the object to be coated, and is deposited on a surface of the object.

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.
