Abstract
A system for manipulating articles, such as irregular mailpieces in the U.S. Postal Service mail processing system, receives an agglomeration of parcels into a first subsystem where the parcels are separated and are passed to a second subsystem where each parcel is manipulated until its addressee label is directed upward. The first subsystem includes a plurality of individually rotatable cylindrical rollers which form a support surface for the parcels. The rollers produce translation of a parcel by cooperative motion or separation of parts of a pile of parcels by differential motion. The second subsystem includes a high-friction, flexible conveyor belt which in a first mode supports a parcel and in a second mode forms a downward loop in which a parcel can be rotated and inverted. The parcels in both subsystems are manipulated by a five-axis robotic arm which is responsive to a machine vision system measuring the position and physical characteristics of each parcel.
