Abstract

See full text

A rotating drum of a rotating drum-type workpiece cleaning device is provided with feed fins that extend helically along the inner circumferential surface of the drum body. The feed fins are, for example, fins in which metal sheets have been folded. On both sides of the feed fins, the angle of the internal corner between the feed fin and the inner circumferential surface of the drum body is an obtuse angle, for example, about 120 degrees. It is possible to prevent or limit the trapping of conveyed workpiece in the internal corner and trapping between adjacent fin sections.
