Abstract:
An electrostatic powder coating apparatus comprising:a heating and degreasing section for heating and degreasing a workpiece;an electrostatic coater for electrostatically adhering powder coat to a surface of the workpiece;a curing section for heating and melting a layer of the electrostatically adhering powder coat to the surface of the workpiece for fixation thereto;a cooling section for cooling the workpiece which has been heated and degreased and the workpiece which has been cured;means for delivering the workpiece along a path through respective sections of the apparatus including the heating and degreasing section, the electrostatic coater, the curing section and the cooling section; wherein the path through the cooling section is composed of a first delivery path passing from the side of the heating and degreasing section through the cooling section to the side of the electrostatic coater, and a second delivery path passing from a side of the curing section through said cooling section to a workpiece discharging side;an upper mechanism group including the electrostatic coater and the curing section is arranged on an upper side of a lower mechanism group including the heating and degreasing section and the cooling section;means for lifting a workpiece that has been delivered to an end portion on a terminal point side of the first delivery path passing through the lower mechanism group up to an end portion on a start point side of the upper delivery path passing through the upper mechanism group; andmeans for lowering a workpiece that has been delivered to the end portion on the terminal point side of the upper delivery path down to the end portion on the start point side of the second delivery path passing through the lower mechanism group.
