ABSTRACT:
A live roller accumulator conveyor has a plurality of zones between its inlet and discharge ends which are arranged in groups. Each zone has a sensor which reacts to the presence of an article therein by deactuating the drive for the adjacent upstream zone in order to provide for accumulation of multiple articles on the conveyor. When the accumulated articles are to be discharged, however, these controls are overriden so that when the zone immediately downstream from a group of zones is cleared, the drives for all of the zones of the next upstream group are actuated simultaneously so that all of the group of articles accumulated therein advance in unison.
