Description

La présente invention a pour objet un dispositif de couteau pour broyeur utilisé dans le domaine de l'alimentaire, et plus particulièrement pour le découpage de la viande.The present invention relates to a knife device for crusher used in the field of food, and more particularly for the cutting of meat.

Dans le domaine de l'industrie alimentaire, les broyeurs prennent place dans une chaîne de transformation où ils permettent de broyer des produits destinés à être incorporés à d'autres pour réaliser une préparation alimentaire.In the field of the food industry, grinders are part of a processing chain where they can grind products intended to be incorporated into others for food preparation.

De manière générale, un tel broyeur comprend 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.In general, such a mill essentially comprises a feed hopper opening into a chamber in which an endless screw pushes the meat towards one or more cutting assemblies each consisting of a star-shaped knife with several branches, curves or not, and a grid with openings larger or smaller.

Chacune des branches présente un tranchant défini par l'angle que font entre elles deux faces, à savoir une première face, disposée en regard de la grille et susceptible de faire de manière générale avec le plan de celle-ci un angle plus ou moins grand, et une seconde face constituant le bord d'attaque, le tranchant étant complété par un méplat, réalisé en extrémité de la première face, dans un plan perpendiculaire à l'axe de rotation, et destiné à permettre le glissement sur la grille.Each of the branches has a cutting edge defined by the angle between them two faces, namely a first face, arranged opposite the grid and likely to make generally with the plane thereof a larger or smaller angle , and a second face constituting the leading edge, the cutting edge being completed by a flat, made at the end of the first face, in a plane perpendicular to the axis of rotation, and intended to allow sliding on the grid.

On notera que le tranchant serait plus performant sans méplat, celui-ci est toutefois indispensable afin d'éviter l'usure de la grille.Note that the edge would be more efficient without flat, it is however essential to prevent wear of the grid.

Le couteau tourne contre la grille, et la viande est poussée contre celle-ci pour être découpée entre le tranchant du couteau et les bords des ouvertures de la grille.The knife turns against the grill, and the meat is pushed against it to be cut between the edge of the knife and the edges of the openings of the grate.

La figure 1 du dessin annexé représente un tel couteau vu de dessous, et qui en l'occurrence comprend quatre branches rectilignes. De manière générale, un tel couteau est une pièce de fonderie affûtée, et réaffûtée par meulage.The figure 1 of the appended drawing represents such a knife seen from below, and which in this case comprises four rectilinear branches. In general, such a knife is a sharpened foundry piece, and grinded by grinding.

La qualité de la coupe dépend de la taille des ouvertures de la grille et de la finesse du tranchant. Or, au gré de l'utilisation, notamment du fait du frottement du couteau contre la grille, le tranchant s'émousse et devient moins performant, puisqu'en effet le méplat s'élargit.The quality of the cut depends on the size of the openings of the grid and the sharpness of the edge. However, according to the use, particularly because of the friction of the knife against the grid, the edge dulls and becomes less efficient, since indeed the flattened out.

I1 convient par conséquent d'affûter régulièrement ces couteaux, ce qui constitue une opération de meulage difficile, car il faut recréer les tranchants de chacune des branches tout en les conservant dans un même plan afin d'en assurer la parfaite coopération avec la grille.It is therefore appropriate to sharpen regularly these knives, which is a difficult grinding operation, because it is necessary to recreate the cutting edges of each branch while keeping them in the same plane to ensure perfect cooperation with the grid.

Les opérations d'affûtage sont ainsi grandes consommatrices de matière, et les couteaux n'ont pas une grande durée de vie.The sharpening operations are thus heavy consumers of material, and the knives do not have a long life.

Des tranchants performants permettent, de manière générale, de diminuer l'énergie nécessaire à l'entraînement des couteaux, et de limiter les problèmes d'échauffement. Cependant, selon la nature de la viande à découper et surtout sa destination, il n'est pas toujours indispensable de disposer de tranchants performants.High performance cutting edges generally make it possible to reduce the energy required to drive the knives, and to limit heating problems. However, depending on the nature of the meat to be cut and especially its destination, it is not always essential to have cutting edge performance.

Il en est tout autrement dans le cas de certaines spécialités alimentaires et plus particulièrement pour la fabrication de saucisson sec, puisque là, la viande doit obligatoirement être découpée finement.It is quite different in the case of certain food specialties and more particularly for the manufacture of dry sausage, since there, the meat must obligatorily be cut up finely.

Ainsi, les couteaux actuellement utilisés pour la découpe de la viande destinée à la fabrication du saucisson sec, ont une durée de vie limitée, et doivent être fréquemment affûtés, et donc remplacés.Thus, knives currently used for cutting meat for the manufacture of dry sausage, have a limited life, and must be frequently sharpened, and therefore replaced.

Pour pallier cet inconvénient, certains ont proposé d'utiliser des couteaux dont chacune des branches est équipée d'une lame interchangeable, ce qui toutefois génère, outre des difficultés de réglage et d'ajustement des surfaces de contact, des problèmes évidents du point de vue de l'hygiène.To overcome this drawback, some have proposed to use knives each of whose branches is equipped with an interchangeable blade, which however generates, in addition to difficulties in adjusting and adjusting the contact surfaces, obvious problems from the point of contact. view of hygiene.

Le document US 4 037 494 décrit un dispositif analogue à savoir une lame adaptable sur un porte-lame, cette lame venant du découpage et du pliage d'une plaque de métal. Cet ensemble porte-lame et lame est également d'un usage limité, voire proscrit aujourd'hui, du fait des difficultés de nettoyage et donc d'hygiène alimentaire.The document US 4,037,494 describes a similar device namely a blade adaptable to a blade holder, this blade coming from the cutting and folding of a metal plate. This blade holder assembly and blade is also of limited use, or even outlawed today, because of the difficulties of cleaning and therefore food hygiene.

Le document GB 2 303 053 expose le même problème, et propose pour y remédier un dispositif de couteau présentant des branches dont le bord d'attaque consiste en une bande de métal dur rapportée et soudée au corps du couteau. Si le fait d'utiliser une bande de métal permet d'identifier aisément la zone de la branche qui doit être active, les opérations d'affûtage nécessitent de systématiquement rectifier par usinage le corps du couteau en arrière de ladite bande afin de dégager celle-ci, ce qui, outre le surcroît de travail, nuit à l'intégrité de liaison entre la bande de métal et le corps de la branche.The document GB 2,303,053 exposes the same problem, and proposes to remedy a knife device having branches whose leading edge consists of a hard metal strip reported and welded to the body of the knife. If the fact of using a metal strip makes it possible to easily identify the zone of the branch that must be active, the sharpening operations require to systematically grind the body of the knife behind the strip in order to clear the strip. This, in addition to the extra work, affects the bonding integrity between the metal strip and the body of the branch.

Par ailleurs, le métal employé pour la fabrication de la bande est de type carbure, ce qui génère une usure rapide de la grille.Furthermore, the metal used for the manufacture of the strip is carbide type, which generates rapid wear of the grid.

On connaît également par le document DE 802 316 un couteau issu de fonderie, dont chacune des branches comporte au niveau de son tranchant un cordon de matière constituant un élément d'usure. Un tel couteau est peu performant, et notamment ne permet pas la découpe de la viande destinée à la fabrication du saucisson sec. Enfin, on connaît également par le document DE 34 14 375 , un couteau présentant des branches courbes, dont la face de glissement de chacune est de largeur allant en s'accroissant de l'extrémité libre vers le moyeu, en sorte que l'affûtage d'un tel couteau est long et peu aisé.It is also known from the document DE 802 316 a knife from the foundry, each of whose branches has at its cutting edge a bead of material constituting a wear element. Such a knife is inefficient, and in particular does not allow the cutting of meat for the manufacture of dry sausage. Finally, it is also known from the document DE 34 14 375 , a knife having curved branches, whose sliding face of each is of width increasing from the free end to the hub, so that the sharpening of such a knife is long and not easy.

La présente invention a pour but de proposer un dispositif de couteau de broyeur permettant de remédier à ces divers inconvénients, notamment par le fait que son tranchant demeure performant sur une durée d'utilisation bien plus longue que celle des couteaux actuellement connus, et que son affûtage est moins complexe à réaliser, et moins consommateur de matière, en sorte que sa durée de vie est bien supérieure à celle desdits couteaux actuellement connus.The object of the present invention is to provide a grinder knife device making it possible to remedy these various drawbacks, in particular by the fact that its cutting edge remains efficient over a much longer period of use than knives currently known, and that its sharpening is less complex to achieve, and less consumer material, so that its life is much longer than said knives currently known.

Le dispositif de couteau de broyeur alimentaire, plus particulièrement destiné au découpage de la viande, selon l'invention, présente une forme d'étoile à plusieurs branches droites ou courbes, obtenu par usinage, destiné à coopérer avec une grille présentant des ouvertures, chacune desdites branches comprenant un tranchant défini par l'angle que font entre elles deux faces, à savoir une première face, qui s'étend dans un plan perpendiculaire à l'axe de rotation, et une seconde face constituant le bord d'attaque, caractérisé en ce que ledit bord d'attaque consiste en la face externe d'une paroi d'épaisseur faible et constante sur sa longueur, et dont le bord extrême consiste en une face qui s'étend dans un plan perpendiculaire à l'axe de rotation.The food mill knife device, more particularly intended for cutting meat, according to the invention, has a star shape with several straight or curved branches, obtained by machining, intended to cooperate with a grid having openings, each said branches comprising a cutting edge defined by the angle between two faces, namely a first face, which extends in a plane perpendicular to the axis of rotation, and a second face constituting the leading edge, characterized in that said leading edge consists of the outer face of a wall of small thickness and constant along its length, and whose extreme edge consists of a face which extends in a plane perpendicular to the axis of rotation .

Au gré de l'utilisation du dispositif de couteau selon l'invention, son usure est réalisée uniquement au niveau de la paroi d'épaisseur faible et constante. Du fait des caractéristiques de cette paroi, la face de glissement demeure de largeur identique, et le tranchant conserve ses performances initiales.According to the use of the knife device according to the invention, its wear is achieved only at the wall of small thickness and constant. Due to the characteristics of this wall, the sliding face remains of identical width, and the cutting edge retains its initial performance.

Les opérations d'affûtage se limitent à un simple surfaçage qui peut être opéré rapidement et de manière moins compliquée que les opérations de meulage, et surtout avec un enlèvement de matière peu important.Sharpening operations are limited to a simple surfacing that can be operated quickly and in a less complicated way than grinding operations, and especially with a small material removal.

Selon une caractéristique additionnelle du dispositif selon l'invention, les branches sont de forme courbe.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, la paroi est d'une épaisseur comprise entre 0,5 et 2, 5 millimètres.According to an additional feature of the device according to the invention, the branches are of curved shape.
According to another additional feature of the device according to the invention, the wall is of a thickness of between 0.5 and 2.5 millimeters.

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 refers to the appended drawing, which represents a non-limiting embodiment thereof.

En référence à la figure 1, on peut voir un dispositif 1 de couteau utilisé actuellement pour découper de la viande en vue de la fabrication de saucisson sec.With reference to the figure 1 a knife device 1 currently used for cutting meat for the manufacture of dry sausage can be seen.

Ce dispositif de couteau 1 présente la forme d'une étoile à quatre branches droites 2, et comporte un trou central 10 destiné au passage et à l'accouplement d'un arbre d'entraînement, non représenté.This knife device 1 has the shape of a star with four straight branches 2, and has a central hole 10 for the passage and coupling of a drive shaft, not shown.

En référence également à la figure 2, qui représente la coupe transversale d'une branche 2 ainsi que d'une grille 3 comportant des trous 30 et avec laquelle le couteau 1 coopère, on peut voir que chacune des branches 2 comporte une première face 20 disposée en regard de la grille 3 et faisant un angle avec le plan de celle-ci, une seconde face 21 constituant le bord d'attaque La liaison entre les deux faces 20 et 21 est réalisée au travers d'un méplat 22 qui s'étend perpendiculairement à l'axe de rotation de dispositif de couteau 1, c'est-à-dire parallèlement à la grille 3, et qui constitue une face de glissement sur la grille 3, l'angle que forment la face 21 et le méplat 22, constituant le tranchant 23.With reference also to the figure 2 , which represents the cross section of a branch 2 and a grid 3 having holes 30 and with which the knife 1 cooperates, it can be seen that each of the branches 2 comprises a first face 20 disposed opposite the grid 3 and making an angle with the plane thereof, a second face 21 constituting the leading edge The connection between the two faces 20 and 21 is formed through a flat portion 22 which extends perpendicular to the axis of knife device rotation 1, that is to say parallel to the grid 3, and which constitutes a sliding face on the grid 3, the angle formed by the face 21 and the flat part 22 constituting the cutting edge 23.

Au gré de l'utilisation du dispositif de couteau 1, c'est à-dire au gré du glissement du méplat 22 contre la grille 3, ce dernier s'élargit ce qui nuit à la qualité de la coupe. Pour affûter le dispositif de couteau, il est donc nécessaire de rectifier toute la face 20, de chacune des branches 2, de rectifier les faces 21 pour qu'elles conservent une bonne hauteur, puis de recréer le méplat 22, pour assurer le glissement sur la grille et éviter d'attaquer celle-ci.At the discretion of the use of the knife device 1, that is to say at the discretion of the sliding of the flat surface 22 against the grid 3, the latter widens which affects the quality of the cut. To sharpen the knife device, it is therefore necessary to correct the entire face 20, of each of the branches 2, to correct the faces 21 so that they maintain a good height, then recreate the flat part 22, to ensure the sliding on the grid and avoid attacking it.

Par ailleurs, les méplats 22 doivent tous se situer dans un même plan perpendiculaire à l'axe de rotation du dispositif de couteau 1, ce qui, on le comprendra, rend encore plus compliquée une opération d'affûtage.Furthermore, the flats 22 must all lie in the same plane perpendicular to the axis of rotation of the knife device 1, which, it will be understood, makes even more complicated a grinding operation.

En référence maintenant aux figures 3 et 4, on peut voir un dispositif de couteau 4 selon l'invention, qui présente également la forme générale d'une étoile à plusieurs branches 5, lesquelles sont préférentiellement courbes. Le dispositif de couteau 4 est percé centralement d'un trou 40 destiné au passage et l'accouplement d'un arbre, non représenté, permettant d'entraîner le dispositif de couteau en rotation autour d'un axe XX' et dans le sens de la flèche R.Referring now to Figures 3 and 4 we can see a knife device 4 according to the invention, which also has the general shape of a star with several branches 5, which are preferably curved. The device knife 4 is pierced centrally with a hole 40 for the passage and the coupling of a shaft, not shown, for driving the knife device in rotation about an axis XX 'and in the direction of the arrow R .

Le dispositif de couteau 4 comporte un côté supérieur 41, visible sur la figure 4 destiné à faire face à l'afflux de matière à découper, et un côté inférieur 42, visible sur la figure 3, destiné à venir au contact d'une grille 3, non représentée, en sorte de coopérer avec celle-ci pour la découpe de ladite matière.The knife device 4 has an upper side 41, visible on the figure 4 intended to cope with the influx of material to be cut, and a lower side 42, visible on the figure 3 , intended to come into contact with a grid 3, not shown, so as to cooperate with it for cutting said material.

Chacune des branches 5 comprend une face convexe 50 qui constitue le bord d'attaque, et qui, selon l'invention, consiste en la face externe d'une paroi 51 dont l'épaisseur est faible, comprise de préférence entre 0,5 et 2,5 millimètres, et surtout constante.Each of the branches 5 comprises a convex face 50 which constitutes the leading edge, and which, according to the invention, consists of the external face of a wall 51 whose thickness is small, preferably between 0.5 and 2.5 millimeters, and above all constant.

L'extrémité libre de cette paroi 51 consiste en une face 52, qui s'étend dans un plan perpendiculaire à l'axe de rotation XX', et qui constitue une face de glissement, et qui forme avec la face 50, un tranchant 53 apte à coopérer avec une grille 3, tel que cela est représenté sur la figure 5.The free end of this wall 51 consists of a face 52, which extends in a plane perpendicular to the axis of rotation XX ', and which constitutes a sliding face, and which forms with the face 50, a cutting edge 53. adapted to cooperate with a grid 3, as shown on the figure 5 .

On comprendra que le frottement de la paroi 51, au travers du méplat 52, provoque bien évidemment l'usure de cette paroi 51, mais que du fait de la constance de son épaisseur, le méplat 52 demeure de largeur constante ce qui n'influe pas sur la qualité de coupe du tranchant 53.It will be understood that the friction of the wall 51, through the flat 52, obviously causes the wear of this wall 51, but that because of the constancy of its thickness, the flat 52 remains of constant width which does not affect not on the cutting quality of the cutting edge 53.

S'il est nécessaire de réaliser un affûtage, celui-ci consiste en une simple opération de surfaçage, sans enlèvement de matière, en sorte d'augmenter la durée de vie du dispositif de couteau 4.If it is necessary to perform a sharpening, it consists of a simple surfacing operation, without removal of material, so as to increase the life of the knife device 4.

Un dispositif de couteau 4 selon l'invention est d'un coût de fabrication supérieur à celui d'un dispositif de couteau actuellement utilisé, mais ce surcoût est largement compensé par la qualité de coupe qu'il procure, sa durée de vie bien supérieure, ainsi que son faible coût de maintenance.A knife device 4 according to the invention has a manufacturing cost higher than that of a knife device currently used, but this extra cost is largely offset by the quality of the cut that it provides, its service life much greater as well as its low maintenance cost.
