ABSTRACT:
Items carried by a conveyor belt are deflected from their original path of travel by deflector members that travel at the same speed as the belt, in some embodiments, or by deflector members that travel in a wave-like motion with the items in other embodiments. In all embodiments, the profile and preselected characteristics of each item are sensed and a computer determines which deflectors to deploy into path-diverting relation to the items. Thus, any pattern of deflectors can be deployed. The deflectors may be deployed gradually as they travel past a trigger member moving a slightly different speed or they may be deployed abruptly when traveling past a fixed position trigger member.
