ROTATING DRUM FOR WORKPIECE CONVEYANCE AND WORKPIECE CLEANING DEVICE

A rotating drum (7) of a rotating drum-type workpiece cleaning device is provided with feed fins (13) that extend helically along the inner circumferential surface (11a) of the drum body (11). The feed fins (13) are, for example, fins in which metal sheets have been folded. On both sides of the feed...

Beschreibung
Zusammenfassung:	A rotating drum (7) of a rotating drum-type workpiece cleaning device is provided with feed fins (13) that extend helically along the inner circumferential surface (11a) of the drum body (11). The feed fins (13) are, for example, fins in which metal sheets have been folded. On both sides of the feed fins (13), the angle (¸) of the internal corner (64) between the feed fin (13) and the inner circumferential surface (11a) of the drum body (11) is an obtuse angle, for example, about 120 degrees. It is possible to prevent or limit the trapping of conveyed workpiece (w) in the internal corner (64) and trapping between adjacent fin sections (13a, 13b).
