ABSTRACT:
A conveyor system in which loads supported by forwardly driven carriers of an overhead power and free conveyor are automatically transferred to a second conveyor arranged below the overhead conveyor at a transfer zone and driven at the same forward speed. The vertical spacing between the overhead and second conveyors is decreased from a greater spacing at which a load is engaged and supported by downwardly extending structure of a carrier to a lesser spacing at which the load is disengaged from the carrier structure and is supported by the second conveyor. As the disengaged carrier and load move forwardly in unison on their respective overhead and second conveyors, the carrier is engaged and moved by a transfer conveyor obliquely to the second conveyor at an increased speed such that the carrier continues to move forwardly in unison with the load while simultaneously moving laterally out of alignment therewith.
