Abstract: A method is provided for sorting incoming products (e.g., chicken butterflies) to be portioned into two or more types of end products (e.g., sandwich portions, strips, nuggets, etc.) to meet production goals. The method includes generally four steps. First, information on incoming products is received. Second, for each incoming product, a parameter value (e.g., the weight of an end product to be produced from the incoming product) is calculated for each of the two or more types of end products that may be produced from the incoming product. Third, the calculated parameter values for the incoming products for the two or more types of end products, respectively, are normalized so as to meet the production goals while at the same time achieving optimum parameter values. Fourth, for each incoming product, the end product with the best (e.g., largest) normalized parameter value is selected as the end product to be produced from the incoming product.

Abstract: A support system (10) for stabilizing a high-pressure feed line (15) in a high-speed water jet food portioner, comprising a rigid span assembly (12) connected at one end to an extendable universal joint (40) that provides rotational motion around two axes (36,37) as well as linear freedom along a third axis (38), and at the other end to a rod-end bearing (17) that permits motion about two axes at a fixed attachment point. The extendable universal joint (40) and the rod-end bearing (17) are each anchored to a fixed point, one on a portioner housing and the other on a cutting carriage such that the rigid span assembly (12) is allowed freedom at one end to move with the rapid and dramatically changing motion of the cutting carriage in order to provide support to the high-pressure feed line (15) mounted thereon, with minimal vibration.

Abstract: A conveyor 12 includes an infeed/scanning section (18) and a cutting/outfeed section (22). Both sections have an endless belt (70) and (180) each driven by a friction drive roller (100) and (200). Adequate frictional load is applied between the endless belts and corresponding drive rollers by tension assemblies, each having a tensioning roller (86), (188) rotatably mounted on a pivot frame structure (112), (220) allowing the weight of the tensioning roller to be applied to the return run of the endless belts. Dampeners (130) (270) are integrated with the tensioning rollers (86) (188) to dampen vibrations in the endless belts (70) (180).

Abstract: A portioning apparatus (10) includes a powered conveyor (12) for carrying workpieces (WP) past a scanning station (14) and past a cutting station (20). Information from the scanning station pertaining to physical parameters of the workpiece is transmitted to a control system (16) which then determines an optimal cutting strategy for the workpiece, which strategy is implemented at the cutting station (20). The length of time required to portion the workpiece is also determined, and this information is used to ascertain whether the speed of the conveyor (12) is optimal or should be changed.
