Abstract
A method and apparatus for transforming a stream of non-singularized objects (e.g., packages) into a stream of singularized objects. A rotating conveyor receives non-singularized objects from an input conveyor and transmits singularized objects to an output conveyor. The rotating conveyor has one or more reversible sectors that independently and selectively drive the objects toward and away from the axis of rotation as the objects are rotated upon the rotating conveyor. The objects may be driven into contact with and urged downstream by a vertical conveyor adjacent to the rotating conveyor and the output conveyor. A return conveyor may remove non-singularized objects from the output conveyor and return those objects to the rotating conveyor. A reinjection conveyor may reinject those objects into the non-singularized stream of the input conveyor to ensure singularization and handle temporary increases in the volume of object flow.
