Abstract
A composite-motion drive unit comprises an electromagnet and a drive shaft extending through a hole defined in the electromagnet. The electromagnet and the drive shaft are energized and actuated independently of each other for driving distribution tables coupled respectively thereto in a composite motion pattern. A combinatorial weighing apparatus incorporating the composite-motion drive unit has sweep conveyors for transferring articles from the distribution tables, and a guide chute rotatable in a horizontal plane for distributing articles to be supplied to the distribution tables.
