  • Method and facility for cutting off hind feet of half carcasses
    Patent number: 6881138
    Abstract: With the intention of performing an optimal cutting of the hind feet (8) of the half carcasses (4), which are advanced stepwise on an overhead conveyor (6) suspended in the hind feet (8), there is indicated a method and a plant for performing an optimal hind foot cutting. According to the invention, cutting of the hind feet (8) occurs by the half carcasses (4) being gripped by pivoting gripping mechanisms (26) the clear of which in the gripping position not allowing the heel joint (29) to pass through this. As the variation of the thickness of the heel joint on a carcass is very small, a lifting of the ham (32) of the half carcass by displacing the gripping mechanisms (26) will result in the position of the thickest point of the heel joint being well-defined, whereby there is achieved a very great uniformity of the hind foot cutting by the same displacement pattern of the gripping mechanisms (26) in cross-wise direction in relation to saw blades (30) situated in a plane well-defined in advance.

  • Laying-down system and vision-based automatic primal cutting system in connection therewith
    Patent number: 6860804
    Abstract: In the primal cutting-up of half carcasses of animals (12), vision systems are known whereby the determination of one or more fix points on the carcasses takes place, and where on the basis of the position of these points a visualization of the ideal cut line is effected. But the primal cutting-up of carcasses (12) has hitherto been carried out with manually-operated saws on the basis of operator evaluation. However, the use of manually-operated saws involves the possibility of deviations in relation to the ideal cut line, and the manual work is very monotonous and fatiguing for the operators.
