Description

APPAREIL A DECOUPER LONGITUDINALEMENT LES CARCASSES D'ANIMAUX DE BOUCHERIE APRES ABATTAGE APPARATUS FOR LONGITUDINALLY CUTTING CARCASES OF BEEF ANIMALS AFTER SLAUGHTERING
La présente invention a pour objet un appareil à découper longitudinalement les carcasses d'animaux de boucherie après abattage.The present invention relates to an apparatus for longitudinally cutting the carcasses of slaughter animals after slaughter.
Il concerne le domaine industriel et commercial de la fabrication et de la diffusion de matériel d'abattage, et propose un produit industriel égales en sectionnant longitudinalement la colonne vertébrale. Il est surtout adapté au traitement des porcs, mais peut être utilisé pour tous les quadrupèdes du même genre, tels que veaux, moutons ou chèvres.It concerns the industrial and commercial field of manufacturing and distribution of slaughtering equipment, and offers an equal industrial product by cutting the spine longitudinally. It is especially suitable for the treatment of pigs, but can be used for all quadrupeds of the same genus, such as calves, sheep or goats.
L'appareil selon l'invention est conçu en particulier pour équiper les installations de fente automatique d'animaux de boucherie suspendus par deux pattes à un transporteur, et comportant un outil de coupe monté sur un support apte à se déplacer verticalement alternativement de haut en bas pour effectuer la fente, et de bas en haut pour se retrouver en position de débuter une nouvelle opération.The apparatus according to the invention is designed in particular to equip the automatic slitting installations for slaughter animals suspended by two legs from a conveyor, and comprising a cutting tool mounted on a support capable of moving vertically alternately up and down. bottom to perform the split, and from bottom to top to find themselves in position to start a new operation.
Les dispositifs de fente d'animaux de boucherie employés actuellement sont généralement conçus pour découper les carcasses suspendues verticalement par les pattes de derrière et sont le plus souvent montés sur un châssis mobile accompagnant les animaux se déplaçant le long d'une chaîne de manutention. Les appareils réalisés à ce jour utilisent dans la plupart des cas des organes de coupes constitués d'une ou deux lames à mouvements alternatifs (cf brevet N FR 2 307 471 du 15 avril 1975), ou d'une scie circulaire (cf brevet N US 1 639 695 du 22/01/1929). Dans les deux cas, la découpe provoque des esquilles ou des particules d'os qui ont tendance à s'insérer dans la viande et nécessitent des nettoyages fréquents du matériel de coupe.The slaughtering devices for slaughter animals currently used are generally designed to cut carcasses suspended vertically by the hind legs and are most often mounted on a movable frame accompanying the animals moving along a handling chain. The devices produced to date use in most cases cutting members consisting of one or two blades with reciprocating movements (see patent N FR 2,307,471 of April 15, 1975), or a circular saw (see patent N US 1,639,695 of 01/22/1929). In both cases, the cutting causes splinters or particles of bone which have tend to insert into meat and require frequent cleaning of cutting equipment.
L'invention a pour but de remédier à ces inconvénients et se propose de réaliser un appareil permettant de découper longitudinalement des carcasses d'animaux de boucherie quelle que soit la nature en assurant une découpe de la colonne vertébrale sans provoquer d'esquilles ou de sciure d'os. Cet appareil permet de réaliser une fente irréprochable en supprimant le risque de fracture des colonnes vertébrales, sans échauffement et sans nécessiter d'eau d'arrosage de la zone de coupe.The object of the invention is to remedy these drawbacks and proposes to produce an apparatus making it possible to cut carcasses of slaughter animals longitudinally whatever the nature, by ensuring a cutting of the spine without causing sawdust or sawdust. back. This device makes it possible to create an impeccable slit, eliminating the risk of fracture of the spinal columns, without heating and without requiring water to cool the cutting area.
Il est constitué d'un couperet rotatif circulaire ou non et dépourvu de dents, entraîné par un moteur et monté à l'extrémité d'un bras support oscillant animé, grâce à une came disposée sous l'extrémité du bras support opposée au couperet, d'un mouvement rapide de montée et de descente de manière à communiquer au couperet une frappe de faible amplitude très rapide sur la colonne vertébrale de l'animal à fendre.It consists of a circular or non-circular rotary chopper and devoid of teeth, driven by a motor and mounted at the end of an animated oscillating support arm, by means of a cam disposed under the end of the support arm opposite the chopper, a rapid movement of ascent and descent so as to communicate to the chopper a strike of low amplitude very quickly on the spine of the animal to be split.
Sur les dessins schématiques annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention : la figure 1 représente une installation automatisée de fente en action équipée de l'appareil de découpe revendiqué, la figure 2 est une vue partielle montrant à une échelle différente le couperet rotatif vu de dessus, la figure 3 est une coupe transversale agrandir du bras support et de la came, et les figures 4 et 5 représentent deux exemples de couperets rotatifs non circulaires.In the appended schematic drawings, given by way of nonlimiting examples of embodiments of the object of the invention: FIG. 1 represents an automated slot installation in action equipped with the claimed cutting device, FIG. 2 is a partial view showing on a different scale the rotary cutter seen from above, FIG. 3 is an enlarged cross-section of the support arm and of the cam, and FIGS. 4 and 5 represent two examples of non-circular rotary cutters.
Le dispositif, figures 1 à 5, est constitué d'un appareil de découpe 1 comportant un couperet rotatif 2 monté à l'extrémité d'un bras support 3 oscillant sur un axe 4, et animé d'un mouvement rapide de montée et de descente donnant un effet de martèlement sur les os à découper grâce à une came 5 disposée sous l'extrémité du bras support 3 opposée au couperet, un ressort de rappel 6 situé au-dessus du même bras support appliquant celui-ci sur la came.The device, Figures 1 to 5, consists of a cutting device 1 comprising a rotary cutter 2 mounted at the end of an arm support 3 oscillating on an axis 4, and animated by a rapid movement of ascent and descent giving a hammering effect on the bones to be cut thanks to a cam 5 arranged under the end of the support arm 3 opposite the chopper, a spring return 6 located above the same support arm applying it on the cam.
Le couperet 2 est entraîné en rotation par un moteur 7 électrique ou pneumatique au moyen d'une courroie 8 ou d'un autre système de transmission. La came 5 est actionnée par un second moteur 9, soit directement (figure 3), soit par l'intermédiaire d'un réducteur.The chopper 2 is driven in rotation by an electric or pneumatic motor 7 by means of a belt 8 or another transmission system. The cam 5 is actuated by a second motor 9, either directly (FIG. 3), or via a reduction gear.
La figure 1 montre le couperet circulaire 2 en action de coupe de la colonne vertébrale 10 d'un porc 11 suspendu au rail de manutention 12 du convoyeur assurant le transport de l'animal au cours des différentes phases d'abattage. L'appareil de découpe 1 peut se mouvoir verticalement et latéralement dans un châssis mobile 13 synchronisé avec la vitesse du convoyeur, ce qui permet de ne pas arrêter la chaîne automatisée au cours des opérations de fente. Le poids de l'appareil de découpe est compensé par un contrepoids 14.Figure 1 shows the circular chopper 2 in cutting action of the spine 10 of a pig 11 suspended from the handling rail 12 of the conveyor ensuring the transport of the animal during the different slaughter phases. The cutting device 1 can move vertically and laterally in a mobile chassis 13 synchronized with the speed of the conveyor, which makes it possible not to stop the automated chain during the slitting operations. The weight of the cutting device is compensated by a counterweight 14.
Le couperet rotatif 2 est de préférence conçu de manière à ce qu'il soit auto-affûté par les os découpés. Toutefois, l'appareil de découpe 1 pourra avantageusement comporter une affûteuse incorporée (non représentée) constituée par exemple de deux meules s'appliquant manuellement ou automatiquement sur les flancs du couperet, sans démontage de ce dernier.The rotary chopper 2 is preferably designed so that it is self-sharpened by the cut bones. However, the cutting device 1 may advantageously include an incorporated sharpener (not shown) consisting for example of two grinding wheels applying manually or automatically on the sides of the chopper, without disassembly of the latter.
Le couperet rotatif 2 pourra être circulaire (figure 1 ), de forme hexagonale (figure 4) ou comporter des éléments en saillie 15 répartis sur sa périphérie (figure 5). Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The rotary chopper 2 may be circular (Figure 1), hexagonal in shape (Figure 4) or have projecting elements 15 distributed around its periphery (Figure 5). The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
