Abstract
An apparatus for cleaning a powder coating booth used to coat elongated articles while oriented vertically includes a pair of opposing vertical walls forming a coating booth, powder spray guns extending through the walls to powder coat articles located therebetween and an overhead conveyor for carrying the elongated articles along a coating line between the walls. A platform mounted to an elevator is vertically movable to any desired elevation in the booth, thereby to enable a cleaning person to clean accumulated powder from the inner surfaces of the walls after a job is finished or when a new color is used. The platform and elevator may be located below the booth, along the coating line. Alternatively, the platform and elevator may be located at a cleaning station away from the coating line and the booth moved to the cleaning station on a wheel-supported rack. With additional booths or cleaning stations, booths may be cleaned while other booths are used for coating, thereby to reduce downtime for the coating line.
