ABSTRACT:
Method and apparatus for the application of grated cheese to pizza shells is provided including mechanism for the automated feeding of cheese to a grating apparatus, intermittent grating of cheese in a predetermined quantity and deposit thereof onto a transfer conveyor, and the intermittent operation of the transfer conveyor for subsequently transferring the cheese particles onto a pizza shell carried by a continuously moving conveyor. The apparatus provides for the automated application of grated cheese to pizza shells in a continuously moving, assembly-line production system in which the pizza shells are transported on an elongated continuously moving conveyor belt. The grating apparatus for the cheese is vertically disposed in superimposed relationship to the pizza shell conveyor and is located immediately above an intermediate transfer conveyor. The cheese is grated and deposited onto the transfer conveyor which is maintained stationary during the grating operation and is driven in timed relationship to the longitudinal displacement of pizza shells beneath the grating apparatus and its associated transfer conveyor. That transfer conveyor is intermittently operated to discharge the grated cheese particles that have been deposited on an upper run thereof, into a same pattern on the surface of the underlying and moving pizza shell. The grating apparatus is also intermittently operated by automated mechanisms and control devices in predetermined relationship to the intermediate transfer conveyor. Operation of the grating apparatus is selectively controllable to effect deposit of a predetermined quantity of cheese particles onto the intermediate transfer conveyor and in a selected pattern. Continuous automated operation of the apparatus is achieved by incorporation of a cheese feeding magazine that is responsive to the quantity of cheese within the grating apparatus, or the absence thereof, to sequentially and automatically feed additional quantities of cheese into the grating apparatus as required through the consumption and discharge of the grated cheese particles.
