  • Patent number: 8276491
    Abstract: An automated sequenced food article tray loading method and apparatus for a high speed slicing machine where food articles can be loaded sequentially into designated and separated lanes of a lift tray and automatically sequentially assume a preload condition. Food article separation is maintained on the lift tray after the food articles are loaded by a plurality of support plates and one or more dividers. A food article sweep mechanism receives the food articles on the lift tray in their separated positions and transfers the food articles into the food article feed mechanism while maintaining the separated positions. The food article sweep mechanism is a substantially open structure without enclosing walls.

  • Patent number: 7993126
    Abstract: Apparatus and methods of modify a reciprocating mold plate patty-forming machine such that a mold plate for a smaller machine can be fit into a larger forming machine. A tooling set for the modification includes a dedicated drawbar configured to mount the smaller mold plate and modified wider spacers to closely meet the smaller mold plate within the forming machine. An adapter system selectively mounts either a first mold plate having a first set of keyholes or a second mold plate having a second set of keyholes, different than the first set of keyholes to a single reciprocating mold plate patty-forming machine. The adapter system can include first and second sets of adapters and a drawbar having provision for connection at opposite ends to driving rods of the drive system.

  • Patent number: 7788885
    Abstract: A method is provided for loading stacked food product into packages. Open top containers are arranged in rows and movable into a loading station. A shuttle conveyor has a retractable and extendable conveying surface, the conveying surface having an end region extendable to a position arranged above the containers of a row of the containers. A guiding and pushing apparatus is arranged above the row and includes guides that are lowered to capture a row of stacked food products on the conveying surface, and plungers within the guides that lower and press a top of the stacks. When the conveying surface is retracted from beneath the guides and the row of containers, the guides are lowered further, adjacent to the containers, and the plungers are lowered with respect to the guides to push the stacks into the containers.

  • Patent number: 7775790
    Abstract: A food molding mechanism for a patty-forming machine that uses a servomotor to drive a crank arrangement. The crank arrangement drives a mold plate. The mechanism uses a reducer with a replaceable output shaft. The reducer engages a servomotor utilizing a double enveloping worm gear providing gear enmeshment across an arc portion of the servomotor main gear. A servomotor driven knockout apparatus comprises a cam and lever arrangement. Oil reservoirs for the knock-out cams are substantially sealed in the mold cover.

  • Patent number: 7623249
    Abstract: A system, suitable for high-speed operation, by which raw product (45), such as a slab of meat, can be accurately processed, such as by slicing into segments of desired weight, comprises a product profiling apparatus (15). The product profiling apparatus (15) measures the profile of the physical process. The product profiling apparatus (15) includes line lasers (75, 85) for directing a line of light across the upper and lower surfaces of the product (45) and visual image cameras (80, 90) directed toward the profile surface to capture, at fixed increments, the product profile. The product may also be weighed and the product density determined from the overall profile measurements. A controller (150) receives this data, and instructs the physical process accordingly.

  • Patent number: 7603936
    Abstract: A mechanism and method is provided for controllably loading multiple food loaves into the slicing station of a continuous slicing machine. The parallel loaves that are engaged by a common loaf feed drive or side-by-side, independent loaf feed drives are engaged by the loaf feed drive or drives simultaneously such that the interface or seam between a preceding loaf and a trailing loaf in different loaf feed paths are located substantially at the same location during slicing of two side-by-side loaf streams. A clamp device is provided that clamps multiple food loaves when loaded to move along the parallel food loaf paths together, wherein the clamp device can be released once the multiple food loaves are simultaneously engaged by the loaf feed drive.

  • Patent number: 7591644
    Abstract: A mold plate for use in a reciprocating mold plate patty-forming apparatus includes a flat body having a plurality of cavities for forming patties. The flat body has a fill side face and an opposite face. A grid pattern of grooves is formed on the second face extending longitudinally and laterally on the second face. The pattern extends a lateral distance that is about equivalent to an overall patty cavity field width. Longitudinal and lateral slots that penetrate though a thickness of the mold plate and flow connect fill side pressure and meat with the pattern of grooves on the second face to balance the pressure on the opposite faces of the flat body.

  • Patent number: 7533513
    Abstract: An apparatus is provided for filling food product drafts into packages. A supply of open top containers are arranged in rows and carried by an elongated web of film and are movable by the web into a fill station. A shuttle conveyor has a retractable and extendable conveying surface, the conveying surface arranged above the fill station and having an end region extendable to a position arranged to deposit food product drafts into the containers of the first row by circulation of the conveying surface. The conveying surface is retractable, or extendable, to reposition the end to a position arranged to deposit food product drafts carried on the conveying surface into the containers of the second row and each subsequent row. A tamping apparatus is carried by the conveyor to retract or extend with the conveying surface end.
