Abstract
A conveyor system includes a diverter positioned between an upstream conveyor and several downstream conveyors and splits or switches a procession of objects conveyed by the upstream conveyor to one of the downstream conveyors where the downstream conveyors are provided with a plurality of sensors along their lengths that detect the presence or absence of objects on the downstream conveyors at different positions along their lengths and supply signals to the diverter to control the diverter to switch between the downstream conveyors to direct the objects conveyed by the upstream conveyor to the one of the downstream conveyors having fewer objects being conveyed by the conveyor and also controls the number of objects delivered by the diverter to the downstream conveyors.
