  • Publication number: 20090064833
    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.

  • Publication number: 20060288832
    Abstract: A method for optimizing yield from a slicing apparatus, includes scanning and weighing a carcass, slab or loaf upstream of a slicing head of the slicing apparatus. The carcass, slab or loaf weight is divided by a desired pre-selected portion weight to determine the number of slices to be made. A remainder portion is allocated to an intermediate position along the carcass, slab or loaf to be sliced from the carcass, slab or loaf before a butt end portion, gripped by a gripper of the slicing apparatus, reaches the slicing head. The butt end portion is pre-arranged to be the desired pre-selected portion weight or at least an acceptable pre-selected portion weight. The butt end portion can then be released by the gripper as a desired or acceptable weight portion.
