Abstract
A method and an apparatus for marshalling objects from one ingoing conveyor to two outgoing conveyors is disclosed. Counting gaps are created by a belt brake operating at a slower speed than the ingoing conveyor. The counting gaps are registered by a pair of photocells, and two gates are maneuvered by a control unit. The gate downstream of the ingoing conveyor is of the single type, and the gate downstream of both of the outgoing conveyors is of the double type. The gates are mechanically interconnected and rotate towards one another in order to marshall the objects onto one or the other of the outgoing conveyors.
