Guiding device for splitting carcasses, apparatus for splitting carcasses comprising such device and method for splitting carcasses

摘要

The apparatus to butcher an animal carcass has a guide (12) which lies against the outer surface of the back of the carcass during cutting. The chassis (22) of the guide has an inner surface against the carcass, and an opposing outer surface (24), and at least one pair (25) of rollers (26, 27) which rotate on axes (28, 29) at the chassis (22). Each roller (26, 27) has an outer surface (49) to ride on the surface of the carcass. The rotary axes (28, 29) of each roller (26,27) in the same pair (25) are aligned in a V-pattern, with the opening aligned in the same direction towards the inner surface of the chassis (22). Each rotating roller (26, 27) has the structure of a truncated cone, with the rotary axis aligned on the supporting rotating axis (28, 29), with the base (50) towards the chassis (22). Each roller (26, 27) has at least one groove around the outer surface (49), symmetrical to the roller rotation around the rotary axis, and preferably a number of coaxial grooves. The angle ( beta ) between the roller axes (28, 2 9) in the same pair (25) is 60-140 degrees . The rollers (26, 27) are of a synthetic polymer material. The guide has the structure of a swingletree (19), with a hub (20) durably mounted to the outer surface (24) of the chassis (22). The chassis (22) has a pair (46) of arms (46a,46b), each carrying a swing rotary roller (26, 27), and preferred two pairs (46, 47) of intersecting arms (46a ,46b; 47a, 47b) for the rollers. Independent claims are included for: (i) a carcass butchering assembly, with cutters to cut into the carcass at least partially on a plane, one guide within the carcass, under the cutters and against the inner surface of the carcass back, and outer guide (12) moves along the outer surface of the back of the carcass; and (ii) a carcass butchering operation, where the cutter is introduced into the carcass through an opening together with the inner guide, and the outer guide (12) is laid against the outer surface of the back of the carcass, the cutter is activated, and the cutting assembly moves along the cutting plane, with the outer guide (12) to keep the cutter in place and on the correct movement alignment.
