Abstract
The invention relates to a method and a device for boning carcass portions of an animal for slaughter. Said carcass portions are in particular abdominal sections on part of the inner surface of which lies a row of more or less encapsulated ribs forming the bone parts which are to be removed. When the method is performed, each abdominal section is held in place and supported, each abdominal section being passed along a number of processing units. According to the invention, the ribs are weakened locally between the ends, and then bent over at a subsequent processing unit so that they break at the location of the weakened areas. By this method, it is possible to remove by machine at least one of the two rib parts formed in this manner.

A process for boning carcass parts of a slaughtered animal, in particular belly pieces on a part of the inner surface of which a row of more or less encapsulated ribs forming the pieces of bone to be removed is situated, the ribs extending inwards essentially parallel to each other from a side edge of the belly piece, each belly piece being held fast and supported and each belly piece being conveyed through a number of processing stations, after which the ribs are removed from the carcass parts, characterized in that the ribs are connected to a backbone part or backbone remains, and in that in at least one processing station a force is exerted on each of the ribs at a point at a distance from the backbone part or backbone remains, as a result of which each rib is weakened at the point in question, after which at a following processing station the belly piece is bent over and each rib is broken at the point mentioned, so that the belly piece is divided into two interconnected parts, a first part containing the backbone part or the backbone remains and the rib pieces extending therefrom to the break points, and a second part containing the other parts of the ribs.
A device for boning a carcass part of a slaughtered animal, the carcass part having a row of more or less encapsulated ribs on an inner surface thereof forming the pieces of bone to be removed, the ribs extending inwards essentially parallel to each other from a side edge of the carcass part, the device comprising a conveyor track with clamping means which can be moved along said track for clamping the carcass part, the clamping means having a supporting element for at least partially supporting the outside of the carcass part, and a number of processing stations disposed along the conveyor track, characterized in that the ribs are connected to a backbone part or backbone remains, and in that the supporting element is designed in such a way that a side part of the carcass part with at least the backbone part or the backbone remains is exposed, and in that at least one first processing station is provided with means for exerting a force locally on the bones of the carcass part, the exerting means connected to drive and control means in such a way that on the passing of the clamping means with the carcass part clamped therein, the exerting means can interact with the ribs at local points between the ends thereof in order at least to weaken said ribs locally, and in that at least one second processing station situated downstream of the at least one first processing station is provided with one or more pressure elements, which can be moved relative to the passing clamping means, and which are connected to drive means and control means in such a way that during the passage of the clamping means the pressure elements can interact with said exposed side part of the carcass part clamped in the clamping means and at a distance from the local points where the exerting means of said at least one first processing station have interacted with the ribs, as a result of which the ribs of said carcass part are broken at the locally weakened points.
