Description

La présente invention a pour objet un dispositif séparateur des éléments durs pour broyeur utilisé dans le domaine de l'industrie alimentaire et plus particulièrement de la découpe de la viande.The subject of the present invention is a device for separating hard elements for mill used in the field of the food industry and more particularly the cutting meat.

Dans le domaine de la découpe industrielle de la viande, on utilise des broyeurs comprenant chacun essentiellement une trémie d'alimentation débouchant dans une chambre où agit une vis sans fin qui pousse la viande vers un ou plusieurs ensembles de coupe constitués chacun d'un couteau en forme d'étoile à plusieurs branches, courbes ou non, et d'une grille présentant des ouvertures plus ou moins grandes. Pour chacun des ensembles de coupe, le couteau peut tourillonner librement sur la grille et éventuellement dans les deux grilles qui l'encadrent si c'est le cas, la ou lesdites grilles étant aptes à être immobilisées dans le broyeur, tandis qu'un arbre est apte à entraíner en rotation les couteaux qu'il traverse, en étant lié à ceux-ci à rotation par l'intermédiaire d'au moins un méplat, tandis que l'une de ses extrémités est liée à un moyen moteur et que l'autre extrémité tourillonne dans le palier d'une grille d'appui ou croisillon.In the area of industrial meat cutting, we uses grinders each essentially comprising a feed hopper opening into a chamber where a auger which pushes the meat towards one or more sets cutters each consisting of a star-shaped knife to several branches, curved or not, and a grid presenting more or less large openings. For each of the sets the knife can spin freely on the grid and possibly in the two grids which surround it if it is the case, the said grid (s) being able to be immobilized in the crusher, while a tree is able to drive in rotation the knives it crosses, being linked to them at rotation through at least one flat, while one of its ends is linked to a motor means and that the other end swivels in the landing of a grid support or cross.

On connaít par ailleurs des dispositifs permettant de trier la viande, c'est-à-dire d'en séparer les éléments durs que sont essentiellement les cartilages, les tendons et les nerfs. Ces dispositifs séparateurs sont destinés à être disposés, optionnellement, à la sortie du broyeur.We also know devices for sorting the meat, that is to say to separate the hard elements that are essentially the cartilages, tendons and nerves. These separating devices are intended to be arranged, optionally, at the outlet of the mill.

Le plus efficace de ces dispositifs consiste en une grille associée à un couteau séparateur qui présente également la forme d'une étoile à plusieurs branches, courbes ou non, chacune comportant sur une face des nervures parallèles, faisant un angle avec l'axe radial de la branche. Les nervures sont destinées à venir au contact de la grille, pour racler cette dernière et, du fait de leur orientation, pour drainer vers le centre les éléments durs qui ne traversent pas la grille. Les éléments durs passent entre le couteau séparateur et la grille pour se retrouver dans le trou central de celle-ci, entre elle et l'arbre d'entraínement, ledit trou central étant à cet effet d'un diamètre très supérieur à celui dudit arbre. Selon une variante, un tube de collecte est vissé dans la plaque d'appui et est engagé dans le trou central de la grille selon un enfoncement réglable avec possibilité de blocage en vue d'adapter sa position par rapport au couteau séparateur. Le tube de collecte est par ailleurs connecté à un tuyau d'évacuation des éléments durs.The most effective of these devices consists of a grid associated with a separating knife which also has the shape a star with several branches, curved or not, each having parallel ribs on one side, making a angle with the radial axis of the branch. The ribs are intended to come into contact with the grid, to scrape this last and, because of their orientation, to drain towards the centers hard elements that do not pass through the grid. The hard elements pass between the separating knife and the grid to find itself in the central hole of it, between it and the drive shaft, said central hole being for this purpose with a diameter much greater than that of said tree. According to one variant, a collection tube is screwed into the support plate and is engaged in the central hole of the grid according to a adjustable recess with possibility of blocking in view to adapt its position relative to the separating knife. The tube is also connected to a drain hose hard elements.

Un tel dispositif présente cependant de nombreux inconvénients, outre des dysfonctionnements et un résultat parfois médiocre, on observe une usure rapide des couteaux et des grilles.However, such a device has many drawbacks, in addition to malfunctions and sometimes poor results, we observes rapid wear of knives and grates.

En effet, lorsque l'on adapte sur le broyeur un dispositif séparateur, le couteau séparateur n'est pas prévu pour tourillonner dans la grille afin de permettre le passage des éléments durs, ce qui supprime un moyen de maintien dudit couteau, tandis que l'extrémité de l'arbre d'entraínement n'est plus tenue du fait du remplacement du palier par le tube de collecte. Le maintien transversal de l'extrémité de l'arbre n'est donc pas assuré, ce qui entraíne, du fait des nombreuses contraintes auxquelles est soumis le couteau séparateur, et qui sont accrues lorsque la viande est congelée, des mouvements du couteau séparateur par rapport à la grille, lesquels génèrent une usure prématurée de ces derniers.In fact, when a device is fitted to the crusher separator, the separator knife is not intended for swirl in the grid to allow the passage of hard elements, which removes a means of maintaining said knife, while the end of the drive shaft is not no longer required due to the replacement of the bearing by the collection. The transverse maintenance of the end of the shaft is therefore not insured, which results, due to the many constraints to which the separating knife is subjected, and which are increased when the meat is frozen, movements of the separator knife with respect to the grid, which generate premature wear of these.

Pour pallier cet inconvénient il a été proposé, outre de maintenir l'extrémité de l'arbre par l'extérieur comme dans les documents US 5.417.376 et US 5.443.214, de remplacer la grille et le tube de collecte du dispositif séparateur, par une grille munie du côté extérieur d'un embout d'accouplement pour un tuyau d'évacuation des éléments durs, et qui est percée de trous répartis sur le pourtour du siège où tourillonne l'extrémité de l'arbre d'entraínement, pour déboucher dans ledit embout d'accouplement. L'extrémité de l'arbre est donc maintenue, et les éléments durs peuvent passer au travers de la grille et être évacués dans le tuyau d'évacuation. De tels dispositifs sont proposés dans les documents US 4.978.077, US 4.699.325, US 4.202.502 et US 4.795.104, ils présentent tous le même inconvénient, celui de ne pas permettre un réglage aisé de la sélection de la taille des éléments durs à évacuer.To overcome this drawback, it has been proposed, in addition to maintain the end of the tree from the outside as in documents US 5,417,376 and US 5,443,214, to replace the grid and the collecting tube of the separating device, by a grid fitted on the outside with a coupling for a hose evacuation of hard elements, and which is pierced with holes distributed around the perimeter of the seat where the end of the the drive shaft, to open into said nozzle coupling. The end of the tree is therefore maintained, and hard elements can pass through the grid and be discharged into the discharge pipe. Such devices are proposed in documents US 4,978,077, US 4,699,325, US 4,202,502 and US 4,795,104, they all have the same disadvantage of not allowing easy adjustment of the selection of the size of the hard elements to be evacuated.

Pour pallier cet inconvénient, le document FR 2.474.342, propose une grille percée également de trous sur le pourtour du siège où tourillonne l'extrémité de l'arbre d'entraínement, tandis que le tube de collecte est maintenu extérieurement contre ladite grille et présente des trous qui, selon l'orientation angulaire dudit tube par rapport à ladite grille, sont susceptibles d'être plus ou moins fermés afin de contrôler la taille des éléments durs. Ce dispositif présente toutefois un autre inconvénient, en effet, le réglage de la sélection de la taille des éléments durs est réalisé en aval de la grille, ce qui provoque de fréquents incidents de colmatage et nécessite d'intervenir.To overcome this drawback, the document FR 2,474,342 proposes a grid also pierced with holes around the edge of the seat where rotates the end of the drive shaft, while the collection tube is held externally against said grid and has holes which, according to the angular orientation of said tube with respect to said grid, are likely to be more or less closed in order to control the size of the elements Hard. However, this device has another drawback, in effect, adjusting the size selection of hard elements is made downstream of the grid, which causes frequent clogging incidents and requires intervention.

La présente invention a pour but de proposer un dispositif séparateur des éléments durs pour broyeur, permettant de remédier aux divers inconvénients précités.The object of the present invention is to propose a device hard element separator for grinder, allowing remedy the various aforementioned drawbacks.

Le dispositif séparateur des éléments durs pour broyeur selon l'invention est du type comprenant, en aval d'un ou de plusieurs ensembles de coupe constitués chacun d'un couteau en forme d'étoile à plusieurs branches et d'une grille présentant des ouvertures plus ou moins grandes, une grille destinée à arrêter lesdits éléments durs et qui est associée à un couteau séparateur conçu apte à drainer lesdits éléments durs vers le centre pour les faire passer entre ledit couteau et ladite grille dans un tube de collecte destiné à être connecté à un tuyau d'évacuation, ledit tube de collecte étant vissé dans une grille d'appui ou croisillon selon un enfoncement réglable avec possibilité de blocage, par l'intermédiaire d'un contre-écrou, en vue d'adapter sa position par rapport audit couteau séparateur, et il se caractérise essentiellement en ce que ledit tube de collecte comporte d'une part un logement axial apte à recevoir l'extrémité de l'arbre d'entraínement des couteaux dudit broyeur en sorte que cette dernière puisse y être tenue transversalement et y tourillonner ; et d'autre part, périphériquement audit logement axial, au moins un canal apte à permettre le transit desdits éléments durs vers ledit tuyau d'évacuation.The device for separating hard elements for a shredder according to the invention is of the type comprising, downstream of one or more cutting sets each consisting of a shaped knife of a star with several branches and a grid presenting more or less large openings, a grid intended to stop said hard elements and that is associated with a knife separator designed capable of draining said hard elements towards the center to pass them between said knife and said grid in a collection tube intended to be connected to a discharge pipe, said collection tube being screwed into a support grid or crosspiece according to an adjustable recess with possibility of blocking, by means of a lock nut, with a view to adapting its position relative to said knife separator, and it is essentially characterized in that said collection tube comprises on the one hand an axial housing adapted to receive the end of the knife drive shaft said mill so that it can be held there transversely and journalling there; And on the other hand, peripherally to said axial housing, at least one channel capable of allow the transit of said hard elements to said pipe discharge.

L'extrémité de l'arbre d'entraínement est ainsi maintenue et peut tourillonner dans le tube de collecte, tandis que les éléments durs peuvent s'échapper par le ou les orifices qui bordent le logement axial dudit tube de collecte, lequel permet, par la possibilité de réglage de son enfoncement, c'est-à-dire l'adaptation de la distance qui sépare son extrémité du couteau, le contrôle de la taille desdits éléments durs.The end of the drive shaft is thus maintained and can rotate in the collection tube, while the hard elements can escape through the opening (s) which border the axial housing of said collection tube, which allows, by the possibility of adjusting its sinking, that is to say adapting the distance between its end of the knife, controlling the size of said hard elements.

Selon une caractéristique additionnelle du dispositif selon l'invention, le logement axial du tube de collecte destiné à recevoir l'extrémité de l'arbre d'entraínement est garni d'une bague.According to an additional characteristic of the device according to the invention, the axial housing of the collection tube intended for receive the end of the drive shaft is lined with a Ring.

L'arbre d'entraínement est souvent de section autre que ronde, pour permettre l'engrènement des couteaux. Le plus fréquemment il présente un ou plusieurs méplats, aussi la bague est de forme adaptée pour permettre à l'extrémité de l'arbre de tourillonner sans jeu dans le logement du tube de collecte.The drive shaft is often of section other than round, to allow the knives to mesh. Most frequently it has one or more flats, so the ring is shaped adapted to allow the end of the shaft to swivel no play in the collecting tube housing.

Selon un mode de réalisation préférentiel du dispositif selon l'invention, le tube de collecte présente un canal axial entouré d'une multitude de canaux périphériques d'axes parallèles audit canal axial.According to a preferred embodiment of the device according to the invention, the collection tube has an axial channel surrounded of a multitude of peripheral channels with axes parallel to said audit axial channel.

Selon une caractéristique additionnelle du mode de réalisation préférentiel du dispositif selon l'invention, le canal axial et les canaux périphériques s'étendent dans le tube de collecte sur une portion de ce dernier.According to an additional characteristic of the embodiment preferred device according to the invention, the axial channel and the peripheral channels extend into the collection tube over a portion of it.

Selon une autre caractéristique additionnelle du mode de réalisation préférentiel du dispositif selon l'invention les extrémités des canaux périphériques du côté du couteau, sont biseautées.According to another additional characteristic of the mode of preferential embodiment of the device according to the invention the ends of the peripheral channels on the knife side, are beveled.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the attached drawing, which represents a non-limiting embodiment.

Dans le dessin annexé :

  • la figure 1 représente une vue schématique partielle en coupe longitudinale d'un dispositif séparateur des éléments durs pour broyeur selon.
  • la figure 2 représente une vue en coupe longitudinale d'une partie du même dispositif séparateur.
  • la figure 3 représente une vue de face de la même partie.
In the attached drawing:
  • FIG. 1 represents a partial schematic view in longitudinal section of a device for separating the hard elements for a mill according to.
  • FIG. 2 represents a view in longitudinal section of part of the same separating device.
  • Figure 3 shows a front view of the same part.

En référence à la figure 1, on peut voir qu'un dispositif séparateur des éléments durs pour broyeur selon l'invention comprend une grille 1 destinée à arrêter les éléments durs, associée à un couteau séparateur 2 mû en rotation par un arbre d'entraínement 3 présentant au moins un méplat. Le couteau séparateur 2 comprend de manière connue des branches 20 munies chacune sur une face de nervures 21 faisant un angle avec l'axe radial de la branche 20 qui les porte, en sorte de racler la surface de la grille et de ramener vers le centre les éléments durs qui ne franchissent pas la grille 1.With reference to FIG. 1, it can be seen that a device hard element separator for mill according to the invention comprises a grid 1 intended to stop the hard elements, associated with a separating knife 2 moved in rotation by a shaft drive 3 having at least one flat. The knife separator 2 comprises in known manner branches 20 provided each on a face of ribs 21 making an angle with the axis radial of the branch 20 which carries them, so as to scrape the grid surface and bring the elements back to the center hard which do not cross the grid 1.

Les éléments durs sont, également de manière connue, évacués par le centre de la grille 1, qui est traversé par un tube de collecte 4 vissé dans une grille d'appui ou croisillon 5 et bloqué sur celle-ci par l'intermédiaire d'un contre-écrou 40.The hard elements are, also in known manner, evacuated by the center of grid 1, which is crossed by a tube of collection 4 screwed into a support grid or cross 5 and blocked on the latter by means of a lock nut 40.

Selon l'invention, comme cela est également visible sur les figures 2 et 3, le tube de collecte 4 comporte au niveau de son extrémité en regard du couteau séparateur 2, sur une longueur correspondant sensiblement à celle de l'extrémité libre 30 de l'arbre d'entraínement 3, un logement cylindrique 41 axial, bordé en périphérie par des canaux 42 parallèles à l'axe du tube 4.According to the invention, as is also visible on the Figures 2 and 3, the collection tube 4 has at its opposite end of the separating knife 2, over a length substantially corresponding to that of the free end 30 of the drive shaft 3, a cylindrical housing 41 axial, bordered at the periphery by channels 42 parallel to the axis of the tube 4.

Le logement 41 est destiné à recevoir l'extrémité libre 30 de l'arbre d'entraínement 3, par l'intermédiaire d'une bague 32. L'extrémité libre 30 de l'arbre 3 munie de sa bague 43 peut ainsi tourillonner librement dans le logement 41 tout en étant maintenue, sans pour cela empêcher l'évacuation des éléments durs qui passent par les canaux périphériques 42, pour se répandre dans le tube 4 avant d'être évacués dans un tuyau souple, non représenté, apte à être connecté à l'autre extrémité du tube 4.The housing 41 is intended to receive the free end 30 of the drive shaft 3, via a ring 32. The free end 30 of the shaft 3 provided with its ring 43 can thus freely rotate in the housing 41 while being maintained, without preventing the evacuation of the elements hard which pass through the peripheral channels 42, to spread in tube 4 before being discharged into a pipe flexible, not shown, suitable for connection at the other end of tube 4.

Le couteau séparateur 2 demeure au contact de la grille 1, laquelle est maintenue par le croisillon 5. la possibilité de déplacer le tube de collecte 4 par rapport au croisillon 5 permet de faire varier l'espace E qui sépare le couteau 2 de l'extrémité 45 du tube de collecte 4, la variation de cet espace E permettant le réglage de la sélection de la taille des éléments durs à évacuer. Ce réglage étant fait en amont du tube de collecte, il n'y a pas de problème de colmatage, comme c'est le cas avec les dispositifs cités plus haut. The separating knife 2 remains in contact with the grid 1, which is maintained by the spider 5. the possibility of move the collection tube 4 relative to the spider 5 makes it possible to vary the space E which separates the knife 2 from the end 45 of the collection tube 4, the variation of this space E allowing adjustment of the size selection of hard elements to evacuate. This adjustment being made upstream of the tube there is no clogging problem, as it is the case with the devices mentioned above.

On notera par ailleurs que les extrémités des canaux périphériques 42 du côté de l'extrémité 45, sont biseautées en sorte de créer des orifices 44 plus larges qui facilitent l'évacuation des éléments durs.It will also be noted that the ends of the channels peripherals 42 on the side of the end 45, are bevelled at kind of create 44 larger holes that make it easier evacuation of hard elements.

Par ailleurs, les canaux périphériques 42 du mode de réalisation représenté sont de section ronde, mais il peuvent très bien présenter une section différente.Furthermore, the peripheral channels 42 of the embodiment shown are of round section, but they may very well present a different section.
