Description

"Machine automatique à trancher des produits non rigides comme des matières alimentaires telles que des viandes"."Automatic machine for slicing non-rigid products such as food materials such as meats".

La présente invention concerne une machine automatique à trancher des produits non rigides tels que des produits alimentaires et notamment des viandes, machine comprenant :

  • un ensemble de coupe à moteur et lame,
  • un chariot à plateau portant le produit à trancher, ce chariot étant mobile par rapport à l'ensemble de coupe pour couper des tranches de produit,
  • un moyen d'évacuation des tranches coupées.
The present invention relates to an automatic machine for slicing non-rigid products such as food products and in particular meats, machine comprising:
  • a motor and blade cutting assembly,
  • a tray trolley carrying the product to be sliced, this trolley being movable relative to the cutting assembly for cutting slices of product,
  • a means of evacuation of the cut slices.

Une telle machine à trancher est notamment connue dans l'industrie alimentaire ou dans ses applications à usage domestique pour couper des produits tels que des blocs de jambon, des saucissons, etc... Cette machine à trancher automatique ou non automatique, c'est-à-dire dont le cycle de fonctionnement est ou non automatique, permet de couper des tranches des produits rappelés ci-dessus sans toutefois avoir à respecter un poids unitaire par tranche.Such a slicing machine is particularly known in the food industry or in its applications for domestic use for cutting products such as ham blocks, sausages, etc. This automatic or non-automatic slicing machine is that is to say, the operating cycle of which is automatic or not, makes it possible to cut slices of the products recalled above without, however, having to respect a unit weight per slice.

Le but de ces machines est de couper des tranches d'épaisseur régulière, souvent relativement fines, et sans souci d'identité de poids d'une tranche à l'autre. En effet, les produits ainsi tranchés sont vendus au poids et non à la tranche.The purpose of these machines is to cut slices of regular thickness, often relatively thin, and without concern for identity of weight from one slice to another. Indeed, the products thus sliced are sold by weight and not by the slice.

Une telle machine a trancher permettrait également de découper des produits moins rigides que du jambon, du saucisson ou du lard, mais ne permettrait pas d'obtenir des tranches de poids uniforme (par exemple 50 grammes ou 100 grammes). En effet, il est certes possible de régler l'épaisseur de la tranche à couper mais rien ne permet d'obtenir avec précision une tranche ayant un poids déterminé ; la seule appréciation est au jugé. Toutefois, cette appréciation n'est pas suffisante pour donner un résultat répétitif lorsqu'on découpe en tranches un morceau de muscle, d'autant plus que la forme de ce morceau n'est pas prismatique ou cylindrique et que pour une épaisseur de tranche constante la variation du poids des tranches coupées peut être importante.Such a slicing machine would also make it possible to cut products that are less rigid than ham, sausage or bacon, but would not allow slices of uniform weight to be obtained (for example 50 grams or 100 grams). Indeed, it is certainly possible to adjust the thickness of the slice to be cut, but there is nothing to precisely obtain a slice having a determined weight; the only assessment is judged. However, this appreciation is not sufficient to give a repetitive result when cutting a piece of muscle into slices, especially since the shape of this piece is not prismatic or cylindrical and that for a constant slice thickness the variation in the weight of the cut slices can be significant.

A plus forte raison, cette machine ne permet pas d'effectuer un tranchage automatique d'un morceau de muscle pour obtenir des tranches de même poids.A fortiori, this machine does not allow automatic cutting of a piece of muscle to obtain slices of the same weight.

Or, dans de nombreux domaines, il est nécessaire de couper des tranches de poids constant ou même, de manière plus générale, de poids prédéterminé.However, in many fields, it is necessary to cut slices of constant weight or even, more generally, of predetermined weight.

Ce besoin existe, en particulier dans l'industrie alimentaire, dans les restaurants de collectivités ou dans des domaines similaires.This need exists, in particular in the food industry, in community restaurants or in similar fields.

Ainsi, la présente invention a pour but de créer une machine à trancher permettant de trancher un morceau de matière relativement souple comme un muscle en des tranches de poids prédéterminé, égaux ou différents d'une tranche à l'autre de manière automatique, suivant une programmation prédéterminée et sans nécessiter de réglage au changement de nouveaux produits de même type.Thus, the present invention aims to create a slicing machine for slicing a piece of relatively flexible material like a muscle into slices of predetermined weight, equal or different from one slice to another automatically, according to a predetermined programming and without requiring adjustment when changing new products of the same type.

A cet effet, l'invention concerne une machine automatique à trancher du type ci-dessus caractérisée en ce qu'elle comprend :

  • un plateau de reconnaissance et de butée,
  • un moyen de détection de la surface de contact du produit à trancher contre le plateau de reconnaissance,
  • un moyen de poussée appliquant le produit contre le plateau,
  • l'angle entre le plateau et le plateau du chariot étant réglable,
  • un moyen de réglage de l'angle du plateau de reconnaissance et du plateau du chariot pour modifier la surface de contact du produit contre le plateau de reconnaissance,
  • un moyen de réglage de la position du plateau par rapport à la lame pour régler l'épaisseur de la tranche à couper,
  • un circuit de commande recevant les informations du moyen de détection et du terminal d'entrée pour commander l'inclinaison relative, la position du plateau, le mouvement d'aller et retour du chariot suivant le nombre de coupes à effectuer et le mouvement du moyen d'évacuation des tranches coupées.
To this end, the invention relates to an automatic slicing machine of the above type, characterized in that it includes:
  • a recognition and stop plate,
  • means for detecting the contact surface of the product to be sliced against the recognition plate,
  • a pushing means applying the product against the plate,
  • the angle between the plate and the plate of the carriage being adjustable,
  • means for adjusting the angle of the recognition plate and the carriage plate to modify the contact surface of the product against the recognition plate,
  • means for adjusting the position of the plate relative to the blade to adjust the thickness of the slice to be cut,
  • a control circuit receiving the information from the detection means and from the input terminal to control the relative inclination, the position of the plate, the movement back and forth of the carriage according to the number of cuts to be made and the movement of the means evacuation of cut slices.

Grâce, d'une part, à l'angle réglable entre la plaque de butée et le plateau portant le morceau de produit à trancher sur le chariot, et du fait que ce produit à trancher est souple et relativement déformable, il est possible, en modifiant l'angle, de modifier la surface de contact. Comme le moyen de détection de surface détermine la surface de contact, et connaissant la densité du produit à trancher, il est facile, en se plaçant dans l'hypothèse assez proche de la réalité, que la tranche a une forme cylindrique au sens mathématique, d'en déterminer le volume et par suite l'épaisseur puisque cette épaisseur est la hauteur du cylindre (volume divisé par la surface). Par le terminal d'entrée, par exemple un clavier, on peut introduire les instructions de tranchage c'est-à-dire la série de tranches à réaliser avec leur poids. Par ce clavier on peut également commander le regroupement ou la séparation des tranches en piles, à nombre de tranches variable, etc...Thanks, on the one hand, to the adjustable angle between the stop plate and the plate carrying the piece of product to be sliced on the carriage, and the fact that this product to be sliced is flexible and relatively deformable, it is possible, by modifying the angle, modifying the contact surface. As the surface detection means determines the contact surface, and knowing the density of the product to be sliced, it is easy, assuming fairly close to reality, that the wafer has a cylindrical shape in the mathematical sense, to determine the volume and consequently the thickness since this thickness is the height of the cylinder (volume divided by the surface). By the input terminal, for example a keyboard, it is possible to introduce the slicing instructions, that is to say the series of slices to be produced with their weight. With this keyboard you can also control the grouping or separation of slices in stacks, with variable number of slices, etc.

Suivant une autre caractéristique, le moyen de détection est un système vidéo comprenant une caméra vidéo, un moyen d'éclairage du produit au niveau de son contour près du plateau de reconnaissance et de butée et un analyseur d'image.According to another characteristic, the detection means is a video system comprising a video camera, a means of lighting the product at its contour near the recognition and abutment plate and an image analyzer.

Le système peut travailler, selon les produits, par réflexion de lumière ou transmission. Dans ce dernier cas, le plateau de reconnaissance et de butée est transparent ou translucide et la caméra du moyen de détection est placée contre la face du plateau, opposée à celle contre laquelle vient le produit, le moyen d'éclairage étant disposé derrière le produit pour assurer un éclairage à contre-jour du contour de la surface de contact du produit sur le plateau de reconnaissance et de butée.The system can work, depending on the products, by light reflection or transmission. In the latter case, the recognition and stop plate is transparent or translucent and the camera of the detection means is placed against the face of the plate, opposite to that against which the product comes, the lighting means being disposed behind the product. to provide backlighting of the contour of the product contact surface on the recognition and stop plate.

Suivant les produits, le plateau du chariot est horizontal ou incliné, par relevage autour d'une articulation, de sorte que le produit est poussé par gravité contre le plateau de reconnaissance et de butée qui est, dans ce cas, incliné vers l'arrière.Depending on the products, the trolley plate is horizontal or inclined, by lifting around a joint, so that the product is pushed by gravity against the recognition and stop plate which is, in this case, inclined towards the rear. .

En général, l'angle du dièdre formé par les plateaux du chariot et du moyen de détection est de l'ordre de 90°.In general, the angle of the dihedral formed by the plates of the carriage and of the detection means is of the order of 90 °.

Suivant une autre caractéristique, le plateau de reconnaissance et de butée est monté sur un support réglable en inclinaison et en translation par rapport au chariot et à la lame.According to another characteristic, the recognition and stop plate is mounted on a support adjustable in inclination and in translation relative to the carriage and to the blade.

Suivant une autre caractéristique, l'ensemble de coupe est une lame rotative à moteur.According to another characteristic, the cutting assembly is a rotary blade with a motor.

Suivant une autre caractéristique, la machine comporte des moyens de nettoyage de la surface du plateau de reconnaissance et de butée contre lequel vient s'appuyer le produit à trancher.According to another characteristic, the machine comprises means for cleaning the surface of the recognition plate and abutment against which the product to be cut comes to bear.

Suivant une autre caractéristique, les moyens de réglage d'inclinaison du plateau du chariot du plateau de reconnaissance et de butée et les moyens de translation du support portant le plateau de reconnaissance et de butée et la lame sont des vérins.According to another characteristic, the means for adjusting the inclination of the plate of the carriage of the recognition and stop plate and the means of translation of the support carrying the recognition and stop plate and the blade are jacks.

La présente invention sera décrite de manière plus détaillée à l'aide des dessins annexés dans lesquels :

  • la figure 1 est une vue de côté de la machine automatique à trancher selon l'invention.
  • la figure 1A est une vue simplifiée de la cinématique de réglage de la machine de la figure 1.
  • la figure 2 est une vue de dessus de la machine de la figure 1.
  • la figure 3 montre une variante de machine à deux chariots.
The present invention will be described in more detail with the aid of the appended drawings in which:
  • Figure 1 is a side view of the automatic slicing machine according to the invention.
  • FIG. 1A is a simplified view of the kinematics for adjusting the machine of FIG. 1.
  • Figure 2 is a top view of the machine of Figure 1.
  • FIG. 3 shows a variant of a machine with two carriages.

Selon les figures 1, 1A et 2, la machine automatique à trancher des produits non rigides tels que des muscles se compose d'un chariot 1 muni d'un plateau 2 relié au chariot par une articulation horizontale 3 ; l'inclinaison du plateau 2 est commandée par un moyen de réglage 4 constitué par un vérin. Le chariot se déplace sur des rails 5 dans la direction perpendiculaire au plan de la figure 1 sous l'action d'un vérin 25. Le plateau 2 comporte également un organe de poussée 6 muni de griffes rétractables 7 ; cet organe de poussée et d'accrochage est mobile dans la direction de la double flèche A. Le plateau porte un produit 8 indiqué en trait interrompu. Sous l'effet de l'inclinaison, et, le cas échéant, avec poussée par l'organe 6, le produit 8 est appliqué contre un plateau de reconnaissance formant butée 9.According to Figures 1, 1A and 2, the automatic machine for slicing non-rigid products such as muscles consists of a carriage 1 provided with a plate 2 connected to the carriage by a horizontal articulation 3; the inclination of the plate 2 is controlled by an adjustment means 4 constituted by a jack. The carriage moves on rails 5 in the direction perpendicular to the plane of Figure 1 under the action of a jack 25. The plate 2 also includes a thrust member 6 provided with retractable claws 7; this pushing and hooking member is movable in the direction of the double arrow A. The plate carries a product 8 indicated in broken lines. Under the effect of the inclination, and, if necessary, with thrust by the member 6, the product 8 is applied against a plate recognition forming stop 9.

Le plateau de reconnaissance 9 est relié à un support 10, représenté schématiquement par un trait, par une articulation 11 et par un moyen de réglage d'inclinaison 12. La plaque de butée est inclinée vers "l'arrière" c'est-à-dire vers le côté gauche du dessin par rapport à la direction verticale. Derrière ce plateau de reconnaissance formant butée 9, qui, dans l'exemple de réalisation est transparent, se trouve un moyen de détection constitué par une caméra vidéo 13 à laquelle est associé un analyseur d'image, non représenté, ainsi que des moyens d'éclairage 14 situés de l'autre côté du plateau 9, derrière le produit 8 de manière à éclairer le produit à contre-jour pour accentuer le contraste entre la surface d'appui S du produit contre le plateau 9 et la partie de ce plateau non recouverte par le produit. L'analyseur d'image peut ainsi mesurer exactement l'aire de la surface de contact S et, connaissant la densité du produit 8, déterminer son volume à partir du poids prédéterminé pour la tranche. Partant de ce volume et de l'aire de la surface S, le système définit l'épaisseur E de la tranche à couper.The recognition plate 9 is connected to a support 10, represented schematically by a line, by an articulation 11 and by an inclination adjustment means 12. The abutment plate is inclined towards the "rear", that is to say - say to the left side of the drawing in relation to the vertical direction. Behind this recognition plate forming a stopper 9, which, in the embodiment is transparent, is a detection means constituted by a video camera 13 with which is associated an image analyzer, not shown, as well as means of lighting 14 located on the other side of the plate 9, behind the product 8 so as to illuminate the product against the light to accentuate the contrast between the support surface S of the product against the plate 9 and the part of this plate not covered by the product. The image analyzer can thus measure exactly the area of the contact surface S and, knowing the density of the product 8, determine its volume from the predetermined weight for the slice. Starting from this volume and the area of the surface S, the system defines the thickness E of the slice to be cut.

La machine comporte également un sous-ensemble de coupe constitué par un moteur 15 et une lame rotative 16.The machine also includes a cutting sub-assembly constituted by a motor 15 and a rotary blade 16.

La lame 16 et le moteur 15 sont fixes dans l'espace et le plateau 9 peut se déplacer en translation et en inclinaison par rapport au couteau 16.The blade 16 and the motor 15 are fixed in space and the plate 9 can move in translation and in inclination relative to the knife 16.

La lame 16 est parallèle au plateau de reconnaissance et de butée 9 et l'écartement de la lame et du plateau correspond à l'épaisseur E de la tranche à couper.The blade 16 is parallel to the recognition and stop plate 9 and the distance between the blade and the plate corresponds to the thickness E of the slice to be cut.

Le réglage de l'inclinaison du plateau 9 se fait par l'intermédiaire du vérin 12 par pivotement autour de l'articulation 11.The inclination of the plate 9 is adjusted by means of the jack 12 by pivoting around the joint 11.

Le support 10 est monté coulissant sur un guide 17 et des éléments de coulissement 18 ; la position de translation dans la direction de la double flèche B est définie par le vérin 19.The support 10 is slidably mounted on a guide 17 and sliding elements 18; the translation position in the direction of the double arrow B is defined by the jack 19.

En d'autres termes, le vérin 19 commande la translation du plateau 9 (grâce aux moyens 17, 18) et le vérin 12 commande l'inclinaison du plateau 9 par pivotement autour de l'axe 11.In other words, the jack 19 controls the translation of the plate 9 (by means 17, 18) and the jack 12 controls the inclination of the plate 9 by pivoting about the axis 11.

Le dessin de la figure 1 montre très schématiquement que le plateau 9 est monté réglable ; le réglage de la lame 16 du sous-ensemble de coupe fixe est assuré automatiquement par le mouvement de réglage du plateau 9.The drawing of Figure 1 very schematically shows that the plate 9 is mounted adjustable; the blade 16 of the fixed cutting sub-assembly is automatically adjusted by the adjustment movement of the plate 9.

Il est à remarquer que le plateau 9 doit être transparent au niveau du détecteur de surface 13, dans ses autres parties il peut ne pas être transparent. Le plateau de reconnaissance 9 est en un matériau transparent de préférence un verre dépoli et de manière non représentée, le plateau 9 est muni de moyens de nettoyage au moins au niveau de la surface transparente pour rendre la détection du contour ou de la surface S aussi précise que possible.It should be noted that the plate 9 must be transparent at the level of the surface detector 13, in its other parts it may not be transparent. The recognition plate 9 is made of a transparent material preferably a frosted glass and, not shown, the plate 9 is provided with cleaning means at least at the transparent surface to make the detection of the contour or of the surface S also specifies as possible.

La figure 1A montre de manière plus schématique que la figure 1, les différents mouvements de réglage de la surface de contact du produit 8 du plateau de reconnaissance 9 d'abord autour de l'axe 3 (rotation dans le sens de la double flèche F pour le plateau 2 du chariot 1), de l'axe 11 (rotation du plateau 9) dans le sens de la double flèche G et translation du plateau 9 toujours par rapport à la lame 16 pour le réglage de l'épaisseur E.FIG. 1A shows more schematically than FIG. 1, the various movements for adjusting the contact surface of the product 8 of the recognition plate 9 first around the axis 3 (rotation in the direction of the double arrow F for the plate 2 of the carriage 1), of the axis 11 (rotation of the plate 9) in the direction of the double arrow G and translation of the plate 9 always relative to the blade 16 for adjusting the thickness E.

La machine automatique comporte également, comme cela apparaît à la figure 2, un circuit de commande 20 muni d'un pupitre de commande 21 tel qu'un clavier. Le circuit de commande 20, relié au moyen de détection 13, reçoit les informations de ce moyen de détection pour commander les moyens de réglage d'inclinaison et d'épaisseur 4, 12, 19 en fonction des données introduites dans le système ; les données introduites dans le circuit 20 sont : la densité du produit à trancher, la surface du produit à trancher, le poids des tranches à couper, l'épaisseur des tranches, le nombre des tranches pour chaque poids. D'autres données peuvent concerner le moyen d'évacuation tel que le tapis convoyeur 22 placé derrière la lame 16 et sur lequel tombent les tranches coupées. Ce convoyeur peut réaliser l'empilage de plusieurs tranches s'il est à l'arrêt pendant la découpe des tranches ; il peut également séparer les tranches les unes des autres en évacuant chaque tranche après sa coupe.The automatic machine also includes, as appears in FIG. 2, a control circuit 20 provided with a control console 21 such as a keyboard. The control circuit 20, connected to the detection means 13, receives the information from this detection means to control the inclination and thickness adjustment means 4, 12, 19 as a function of the data entered in the system; the data entered in circuit 20 are: the density of the product to be sliced, the surface of the product to be sliced, the weight of the slices to be cut, the thickness of the slices, the number of slices for each weight. Other data may relate to the evacuation means such as the conveyor belt 22 placed behind the blade 16 and on which the cut slices fall. This conveyor can stack several slices if it is stopped while cutting the slices; it can also separate the slices from each other by removing each slice after it has been cut.

Dans cette figure, la ligne de coupe est représentée en pointillés 24, à droite, en travers du produit 8. Toutefois pour le tranchage le chariot 1 avec le produit 8 se déplacent à gauche contre la lame 16.In this figure, the cutting line is shown in dotted lines 24, on the right, across the product 8. However for the slicing, the carriage 1 with the product 8 moves to the left against the blade 16.

Suivant les produits à trancher, en particulier s'il s'agit de denrées périssables comme de la viande, l'ensemble de la machine est placé dans un local réfrigéré assurant en même temps la ventilation du moteur 15 et du moyen 13. Elle peut également être entourée par une enceinte 23 réfrigérée, les autres parties du local étant alors à une température moins basse.Depending on the products to be sliced, in particular in the case of perishable goods such as meat, the whole machine is placed in a refrigerated room ensuring at the same time the ventilation of the motor 15 and of the means 13. It can also be surrounded by a refrigerated enclosure 23, the other parts of the room then being at a lower temperature.

Des moyens de protection, non représentés, sont prévus à la fois au niveau du chariot ou autres parties mobiles et près du sous-ensemble de coupe.Protective means, not shown, are provided both at the level of the carriage or other mobile parts and near the cutting sub-assembly.

Dans le cas de produits alimentaires, des buses de nettoyage sont prévues sur la machine, à l'intérieur de l'enceinte pour assurer son nettoyage autant de fois que nécessaire.In the case of food products, cleaning nozzles are provided on the machine, inside the enclosure to ensure its cleaning as many times as necessary.

La figure 3 montre une variante de la machine décrite ci-dessus en reprenant les mêmes références qu'aux figures 1 et 2 pour les éléments identiques ou similaires. Selon cette variante, le chariot 1 est complété par un chariot 1′, identique, de manière à permettre un chargement du plateau 2, 2′ des chariots 1 ou 1′ en temps masqué. En effet, pendant que le produit 8 du chariot 1 est tranché, on charge un produit 8′ sur le chariot 1′. Ce chariot 1′ vient alors se mettre en place dans la zone de détection et de coupe et le chariot 1 est sorti de cette zone pour recevoir son nouveau chargement.Figure 3 shows a variant of the machine described above using the same references as in Figures 1 and 2 for identical or similar elements. According to this variant, the carriage 1 is completed by an identical carriage 1 ′, so as to allow loading of the plate 2, 2 ′ of the carriages 1 or 1 ′ in masked time. Indeed, while the product 8 of the carriage 1 is sliced, a product 8 ′ is loaded onto the carriage 1 ′. This carriage 1 ′ then comes into place in the detection and cutting zone and the carriage 1 is taken out of this zone to receive its new load.

La machine à trancher fonctionne comme suit au niveau de la détection et du tranchage :The slicing machine works as follows in terms of detection and slicing:

Ayant introduit par le clavier 21, les informations relatives au poids, à la surface ou à l'épaisseur et au nombre de tranches à couper, on fait passer le chariot 2 (ou 2′) dans la zone de coupe pour mettre le produit 8 (ou 8′) en appui contre le plateau de reconnaissance 9, fixe en position (par rapport au chariot). Le moyen de détection 13 détecte alors la surface de contacts du produit 8 contre le plateau 9. Si cette surface est suffisante et surtout si elle est compatible avec la plage d'épaisseur autorisée pour la tranche à découper (limite inférieure, limite supérieure), le chariot 2 continue son déplacement dans la direction de la flèche C en glissant sur le plateau 9 pour conduire le produit 8 contre la lame 16 qui tranche par rotation. La tranche coupée tombe sur le tapis convoyeur 22. Lorsque la coupe est terminée, le chariot 2 revient dans le sens opposé (flèche D) et remet de nouveau le produit 8 contre le plateau de reconnaissance 9. Le moyen de détection 13 effectue une nouvelle détection puis il y a coupe et le cycle se poursuit.Having entered via the keyboard 21, the information relating to the weight, the surface or the thickness and the number of slices to be cut, the carriage 2 (or 2 ′) is passed through the cutting zone to place the product 8 (or 8 ′) bearing against the recognition plate 9, fixed in position (relative to the carriage). The detection means 13 then detects the contact surface of the product 8 against the plate 9. If this surface is sufficient and especially if it is compatible with the range of thickness authorized for the wafer to be cut (lower limit, upper limit), the carriage 2 continues its movement in the direction of arrow C by sliding on the plate 9 to drive the product 8 against the blade 16 which cuts by rotation. The cut slice falls on the conveyor belt 22. When the cut is finished, the carriage 2 returns in the opposite direction (arrow D) and again puts the product 8 against the recognition plate 9. The detection means 13 performs a new detection then there is cut and the cycle is continues.

Dans le cas où la surface de contact du produit 8 et du plateau de reconnaissance 9 est trop faible, le circuit de commande 20 modifie l'inclinaison du plateau 2 par rapport au plateau de reconnaissance pour augmenter la surface de contact du produit 8 avec le plateau. Cette analyse se fait en continu. Lorsque la surface de contact est suffisante, on procède à la coupe.In the case where the contact surface of the product 8 and of the recognition plate 9 is too small, the control circuit 20 modifies the inclination of the plate 2 relative to the recognition plate to increase the contact surface of the product 8 with the tray. This analysis is done continuously. When the contact surface is sufficient, the cutting is carried out.

Dans le contraire où la surface de contact initiale du produit 8 et de la plaque de butée 9 serait trop grande, le circuit de commande 20 affiche cette situation qui nécessite une intervention du conducteur de la machine.In the opposite case where the initial contact surface of the product 8 and the stop plate 9 would be too large, the control circuit 20 displays this situation which requires intervention by the operator of the machine.

Si l'inclinaison obtenue par le plateau 2 n'est pas suffisante, il est possible de modifier encore plus cette inclinaison en agissant sur le plateau 9 par son vérin de réglage 12 agissant sur le plateau 9 qui pivote autour de l'articulation 11. Enfin, il est possible d'agir sur l'épaisseur E de la tranche à l'aide du vérin de réglage 19 qui modifie la distance séparant le plateau de reconnaissance 9 et le couteau 16.If the inclination obtained by the plate 2 is not sufficient, it is possible to modify this inclination even more by acting on the plate 9 by its adjustment cylinder 12 acting on the plate 9 which pivots around the articulation 11. Finally, it is possible to act on the thickness E of the wafer using the adjustment jack 19 which modifies the distance separating the recognition plate 9 and the knife 16.

Dans le cas du tranchage automatique de viande il est intéressant de pouvoir choisir plusieurs épaisseurs de tranches par exemple de 5 à 20 mm et de 20 à 50 mm.In the case of automatic meat slicing, it is advantageous to be able to choose several thicknesses of slices, for example from 5 to 20 mm and from 20 to 50 mm.

Enfin, il convient d'indiquer que différentes modifications et variantes sont possibles dans le cadre de l'invention, en particulier les vérins ou actionneurs peuvent être, mécaniques, hydrauliques, pneumatiques ou électriques.Finally, it should be noted that different modifications and variants are possible within the framework of the invention, in particular the jacks or actuators can be, mechanical, hydraulic, pneumatic or electric.
