ABSTRACT:
Apparatus and method are provided for receiving a flow of packages such as parcels or bundles, dividing it into plural streams for easier singulation, singulating each such stream, and delivering the produced packages one at a time to a user, each stream being provided to a different user. Downstream sensors are used to control a deflector which in turn divides a received flow of packages into multiple such flows and apportions the received packages among the two output flows. Singulation of each such output flow is accomplished by a plurality of inclined belts which each moves a received package upward and over its peak to drop for entry into the next stage downstream, thereby singulating the received flow in stages. These belt stages are individually controlled by further downstream sensors and motors which prevent movement of upstream such belt(s) if one or more packages, indicating a flow blockage, is sensed downstream. The output of the singulator is provided to a slide that has a series of motor-controlled detents to deliver packages to the downstream user one at a time.
