Powder coating apparatus and non-transitory computer readable medium

摘要

A powder coating apparatus includes a specific transport device that transports an object to be coated, and a specific applying unit, a specific heating device, and a specific control device, wherein the applying unit is disposed to oppose a surface to be coated of the transported object to be coated, applies a charged thermosetting powder coating material onto a surface to be coated of the object to be coated, and includes an applying section and a supplying section, the heating device heats a powder particle layer of the powder coating material so as to be thermally cured, and the control device controls a speed ratio between a transport speed of the object to be coated and a rotation speed of an applying member.

1. A powder coating apparatus comprising:
a transport device that transports an object to be coated; and an applying unit, a heating device, and a control device, wherein the applying unit is disposed to oppose a surface to be coated of the transported object to be coated, applies a charged thermosetting powder coating material onto a surface to be coated of the object to be coated, and includes at least one applying section each having a cylindrical or columnar applying member that rotates in the same direction as a transport direction of the object to be coated and causes the powder coating material that adheres to a surface of the applying section to be transferred and applied onto the surface to be coated of the object to be coated by a potential difference between the applying section and the surface to be coated of the object to be coated, and a supplying section associated with each applying section, each supplying section comprising from 2 to 5 cylindrical or columnar supplying members arranged along a circumferential direction of the applying member, the supplying section supplying the powder coating material onto a surface of the applying member, wherein the heating device heats a powder particle layer of the powder coating material applied onto the surface to be coated of the object to be coated, so as to be thermally cured, and wherein the control device controls a speed ratio between a transport speed of the object to be coated and a rotation speed of the applying member so that a thickness of the powder particle layer of the powder coating material applied by the applying unit onto the surface to be coated of the object to be coated becomes a predetermined thickness.
