Aligning workpieces for attaching press studs or rivets etc. - has profiled scooping bars attached to inner surface of inner and outer shell of rotatable drum

摘要

Equipment for arranging workpieces for machines for attaching press studs, rivets, hooks and similar parts includes equipment for storing and automatically arranging the workpieces and for guiding them to a transferring position. The equipment consists of a rotatable arranging drum (4) with a cylindrical outer shell (5) and a concentric inner shell (7). The outer shell (5) and the inner shell (7) form between them a hopper for the workpieces. Attached to the cylindrical inner surfaces of the shells (5, 7) are interchangeable bars (9, 10) for arranging and conveying the workpieces. The bars (9, 10) are profiled to suit the workpieces. During rotating movement of the drum (4) the workpieces are scooped from the sumps of the outer and inner shell (5, 7) by the profiles of the arranging and conveying bars (9, 10) and any wrong positioned work pieces are returned.
