Abstract: An automated sequenced food article tray loading method and apparatus for a 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. 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.

Abstract: A food article end location detecting system for a food article slicing machine.

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.
