Abstract:
1. A conveyor assembly, comprising: 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 connected to the tray and supporting the tray during lateral movement; a motor for powering a drive pulley about a drive pulley axis; a driven pulley powered by a drive pulley; a flexible member interconnecting the drive pulley and the driven pulley, the driven pulley mounted to one of the plurality of legs and the tray and rotatable about a driven pulley axis; the driven pulley having an eccentric pulley axis, thereby causing the tray to move in the forward direction and the backward direction; and a tension mechanism to take up slack in the flexible member such that the flexible member returns the tray by moving the tray in the other of the forward direction and the backward direction.
