Abstract
The invention relates to a process and machine usable in mass-slaughtering for pulling off the belly strips from a hog carcass. The machine according to the invention is characterized in that it comprises an optical type sensor comprising a cell mounted on a supporting structure and capable of assessing the height of the suspended hog, between a reference place traversing the hooking bar on which the hog is suspended, and the plane traversing the hog's snout, and capable also to stop the vertical movement of the structure so as to place the head at a height varying between 700 mm and 900 mm above the plane.
Claims17
Machine for pulling off the belly strips from a hog of the type comprising means for suspending an eviscerated hog carcass by means of a hooking bar engaged in the Achilles tendon of the hog's hind legs, in order to introduce in the open rib cage of the hog, a clamp comprising jaws with outwardly directed active members, to place the active jaws substantially inside the plane of the lower end portions of the belly strips lining the inner faces of the hog's sides, with a view to gripping said end portions and pulling them off, and then to raise the clamp for pulling off the strips, machine wherein, in order to define the plane of the lower end portions of the belly strips, means are provided for:
- determining the vertical height (H) of the suspended hog between a horizontal plane (PL) traversing the hooking bar engaged in the Achille's tendons, and a horizontal plane (PL') traversing the hog's snout,
- placing the clamp at a height (h.sub.2) varying between 700 and 900 mm from the plane (PL').
Machine for pulling off the belly strips from a suspended hog carcass, of the type comprising a supporting structure which can be moved vertically by a motor over support and guide rails mounted on a frame, a chassis carried by the structure and which can be moved horizontally by a motor and forms a vertical pivot, a clamp equipped with two parallel jaws which are in the form of a penetrating head capable of being introduced between the lips of the thoracic opening of a suspended hog in order to grip and pull off the belly strips lining the inner faces of the hog's sides, and a sensor for sensing an approximate plane permitting the determination of the base of the belly strips, machine wherein the sensor is an optical type sensor and comprises a cell mounted on the structure and capable of assessing the height of the suspended hog, between a reference plane traversing the beam on which the hog is suspended and a plane traversing the hog's snout, and capable also of stopping the vertical movement of the structure in order to place the head at a height varying between 700 mm and 900 mm above the plane traversing the snout.
