Abstract

In a series of successive operations the shoulder bone is first removed, the backbone cut for the whole of its length, the collar bond removed and the ribs detached. The machine comprises a vertical, open structure inside which the quarter is suspended, clamped and located by fluid power cylinders, while a splitting blade actuated by a fluid power cylinder extracts the shoulder. The quarter is released, laid flat and steadied by fluid powered members and conveyed across a backbone rotary cutter. Vertical descent of a blade actuated by a fluid power cylinder cuts out the collar bone. The ribs are cut and then milled by advancing the quarter under pressure across a controa-rotating square section cutter with sharpened corners. The quarter is automatically transferred between boning stations by mechanical handling. This elimn-eliminates arduous man-handling and reduces labour cost of the prod..

Description

L'objet de l'invention concerne un ensemble fonctionnel pour désosser les quartiers de viande de boucherie. The object of the invention relates to a functional assembly for boning the quarters of butcher's meat.

Il est destiné à assurer en une opération continue sans aucune manutention le décollage de l'épaule, le fraisage de la colone vertébrale, l'enlèvement des colliers ainsi que le dégagement des côtes. It is intended to ensure in a continuous operation without any handling the takeoff of the shoulder, the milling of the vertebral column, the removal of the collars as well as the release of the ribs.

Jusqu'à ce jour il existait des appareillages distincts pour effectuer ces désossages successifs demandant un transfert manuel poiir passer d'une machine à l'autre-. Up to this day, there were separate devices for performing these successive bonings requiring manual transfer to pass from one machine to another.

L'objet de l'invention supprime ces inconvénients et permet par des moyens de liaison de passer immédiatement et automatiquement d'une opération de désossage à 1' autre afin d'amender en fin de parcours la carcasse prête à la consommation. The object of the invention eliminates these drawbacks and allows, by means of connection, to pass immediately and automatically from one boning operation to another in order to amend the carcass ready for consumption at the end of the journey.

Il est constitué par un bâti unique et la combinaison des dispositifs verticaux pour l'enlèvement des épaules avec ceux horizontaux pour le fraisage des colonnes vertébrales, l'enlèvement des colliers ainsi que le fraisage des os de côtelettes soumis en fin de course à 1' action d'un carré à arêtes débordantespour séparation des chairs attenantes. It consists of a single frame and the combination of vertical devices for removing the shoulders with horizontal devices for milling the spines, removing the necklaces as well as milling the chop bones submitted at the end of the stroke to 1 ' action of a square with overhanging edges to separate adjoining flesh.

La figure 1 représente vu en élévation le dispositif dans son ensemble.In the accompanying drawings, formed by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows in elevation the device as a whole.

La figure 2 montre le détail constructif du carré à arêtes débordantes. Figure 2 shows the constructive detail of the square with projecting edges.

La figure 3 représente le désossement des côtes. Figure 3 shows the boning of the ribs.

L ' appareillage est constitué par un bâti unique avec secteur vertical 1 et secteur horizontal 2. The apparatus consists of a single frame with vertical sector 1 and horizontal sector 2.

Le bâti vertical comporte trois vérins positionneurs 3, 4, 5 maintenant le quartier avant 6 amené en place par la tige 7 avec crochet 8. Une fois mis en place le vérin 9 avec son outil 10 procéde à l'enlèvement de l'épaule, ainsi qu'à son détachement. The vertical frame comprises three positioning jacks 3, 4, 5 holding the front quarter 6 brought into place by the rod 7 with hook 8. Once the jack 9 has been put in place with its tool 10, remove the shoulder, as well as his detachment.

Le vérin 5 relache son emprise en ouvrant sa pince 11 et le quartier est pris par les bras 12, 13 qui le stabilisent de façon que la colonne vertébrale 14 soit soummise aux effets de la fraise 15 sur toute sa longueur. The jack 5 releases its grip by opening its clamp 11 and the quarter is taken up by the arms 12, 13 which stabilize it so that the spine 14 is subjected to the effects of the cutter 15 over its entire length.

Le mouvement translatif amène la pièce sous le couteau vertical 26 qui sectionne le collier. The translational movement brings the piece under the vertical knife 26 which cuts the collar.

Ces couteaux 26 sont doubles et juxtaposés de façon que les quartiers avants séparés se présentent droite et gauche sous ces couteaux. These knives 26 are double and juxtaposed so that the separate front quarters appear right and left under these knives.

Le système de verrouillage s'ouvre et libère les quartiers qui prenne.s. ,position 16. Il est alors repris par les rouleaux de blocage 17 après avoir été retourné par sa chute ayant provoqué son basculement. Les côtes 18 vont se trouver face à la fraise 19 qui enlève le 80% de l'épaisseur des os. Les rouleaux entraineurs 20 font avancer le quartier vers le carré 21 dont les arêtes débordantes 22, 23, 24, 25 détachant la chair des os. Ce carré tourne en sens opposé à l'avancement et décolle la chair attenante aux os. Le quartier prend la position 26 et le carré 21 écarte la chair et la détache des côtes figure 3. The locking system opens and releases the neighborhoods that take hold. , position 16. It is then taken up by the blocking rollers 17 after having been overturned by its fall having caused it to tip over. The ribs 18 will be facing the cutter 19 which removes 80% of the thickness of the bones. The drive rollers 20 advance the quarter towards the square 21 whose projecting edges 22, 23, 24, 25 detaching the flesh from the bones. This square turns in the opposite direction to advancement and takes off the flesh adjoining the bones. The quarter takes position 26 and the square 21 spreads the flesh and detaches it from the ribs in Figure 3.

Ce carré à arêtes débordantes effectue le désossage des côtes sans perte ni déchet de chair comestible. This square with overhanging edges performs boning of the ribs without loss or waste of edible flesh.

Toutefois les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équivalents, comme d ' ailleuirs les matières utilisées pour leur fabrication,sans changer pour cela la conception générale de l'invention qui vient d ' être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as well as the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
