ABSTRACT:
Empty cartons are automatically fed by a conveying system to a plurality of packing machines in accordance with the carton demand of each machine. The packing machines operate to fill the cartons with a product such as bulk fruit for example. An accumulation conveyor receives open-topped empty cartons which have been formed either by hand or by a carton set-up machine. The cartons can accumulate upon the conveyor in a single file series and are fed in order to a singulator. The singulator discharges an empty carton only upon demand by one of the packing machines. Such a carton is carried by a feed conveyor along a path to a plurality of feed units one of which will be programmed to stop the movement of the carton along the feed conveyor path and shift it laterally toward the appropriate packing machine. Control means sense the need for cartons at each packing machine and direct the singulator and feed units to feed a single empty carton to the packing machine which requires it. The entire carton feeding system can be located on one floor level, or, in a modified form of the invention, the singulator can operate to lower cartons from an upper floor level to a lower floor level before discharging the cartons for delivery to the packing machines.
