ABSTRACT:
A differential impulse conveyor (10) includes a tray (12) laterally moveable in a forward direction at a first speed and in a backward direction at a second speed greater than the first speed, thereby moving goods along the tray. A plurality of legs (18, 20) support the tray during lateral movement, and a motor (30) powers a drive pulley (30). A driven pulley (36) is powered by the drive pulley, and a flexible member (34) interconnects the driven pulley and the drive pulley. At least the driven pulley has an eccentric pulley axis, thereby imparting lateral movement to the tray. A tension mechanism (38, 40) is provided to take up slack in the flexible member.
