Abstract

An automated feeder transports pastry product dishes and/or moulds and includes a movable headstock arranged transversely above a first conveyor. The headstock includes an upper plate, a main linear actuator attached thereto, a lower mobile plate extendable by the main linear actuator, and a plurality of magnetic elements attached to the lower mobile plate. The magnetic elements hold a plurality of metallic plates in a predetermined arrangement. The headstock also includes at least two secondary vertical linear actuators disposed on the upper plate for actuating a releasing mechanism to dislodge the dishes from the magnetic elements and a transportation mechanism to provide longitudinal movement along a pair of longitudinal rails. The transportation mechanism permits the headstock to move between a first position over the first conveyor to a second position over a second.
