Abstract
A differential impulse conveyor () includes a tray () 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 () support the tray during lateral movement, and a motor () powers a drive pulley (). A driven pulley () is powered by the drive pulley, and a flexible member () 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 () is provided to take up slack in the flexible member.
