Description

DISPOSITIF DE DECOLLEMENT DE FROMAGES  DEVICE FOR DECOLATING CHEESE
DOMAINE TECHNIQUE DE L'INVENTION TECHNICAL FIELD OF THE INVENTION
La présente invention concerne le traitement d'au moins un fromage en cours d'affinage ou de maturation sur un support tel qu'une planche.  The present invention relates to the treatment of at least one cheese being ripened or matured on a support such as a board.
Pendant la maturation et l'affinage d'un fromage, il est souvent nécessaire de procéder à diverses manipulations telles que des brossages ou nettoyages de ses faces latérale, supérieure et inférieure. Il peut être également nécessaire de retourner fréquemment le fromage sur sa planche afin d'en assurer une maturation et un affinage homogènes.  During the ripening and ripening of a cheese, it is often necessary to carry out various manipulations such as brushing or cleaning of its lateral, upper and lower faces. It may also be necessary to frequently return the cheese to its board to ensure a smooth maturation and refinement.
Il se présente cependant souvent l'inconvénient que le fromage a tendance à adhérer à la planche sur laquelle il repose. Le fromage doit donc être séparé de la planche préalablement à la réalisation des opérations de brossage et/ou retournement.  However, it often presents the disadvantage that the cheese tends to adhere to the board on which it rests. The cheese must therefore be separated from the board prior to carrying out the brushing and / or turning operations.
Un décollement manuel est long, et présente des risques de détérioration du fromage dans sa forme, ce qui le rendrait impropre à la vente.  A manual separation is long, and presents risks of deterioration of the cheese in its form, which would make it unfit for sale.
En outre, le décollement manuel est une tâche répétitive, d'autant plus pénible que des opérations de brossage et de retournement doivent parfois être effectuées à une fréquence très élevée (tous les trois jours par exemple).  In addition, the manual separation is a repetitive task, all the more painful as brushing and turning operations must sometimes be performed at a very high frequency (every three days for example).
Enfin, l'environnement de travail est généralement sombre, humide, froid, poussiéreux et saturé en ammoniac, ce qui est mal supporté par des opérateurs manuels.  Finally, the working environment is generally dark, humid, cold, dusty and saturated with ammonia, which is poorly supported by manual operators.
Le document DE 21 50 455 A1 décrit un dispositif de retournement de fromages. Les fromages, préalablement à leur retournement, sont décollés de la planche sur laquelle ils reposent. Pour ce faire, les fromages sont saisis par des pinces de préhension, puis la planche est abaissée. Lors du déplacement relatif des pinces de préhension à l'écart de la planche, il se produit un décollement du fromage par l'induction d'un arrachement dans la zone d'adhérence entre le fromage et la planche. Un tel arrachement est souvent source de déformations accidentelles du fromage, rendant ce dernier impropre à la vente.  DE 21 50 455 A1 discloses a cheese turning device. The cheeses, before their turn, are taken off the board on which they rest. To do this, the cheeses are grasped by gripping tongs, then the board is lowered. During the relative movement of the gripping tongs away from the board, there is a detachment of the cheese by the induction of tearing in the adhesion zone between the cheese and the board. Such tearing is often a source of accidental deformations of the cheese, rendering it unfit for sale.
EXPOSE DE L'INVENTION  SUMMARY OF THE INVENTION
Le problème proposé par l'invention est de permettre un décollement automatisé et efficace d'un fromage vis-à-vis du support sur lequel il repose, et ce en limitant les risques de détérioration du fromage dans sa forme, ce qui le rendrait impropre à la vente aux consommateurs.  The problem proposed by the invention is to allow an automated and effective detachment of a cheese vis-à-vis the support on which it is based, and this by limiting the risk of deterioration of the cheese in its shape, which would make it unsuitable for sale to consumers.
Pour atteindre ces objets ainsi que d'autres, l'invention propose un dispositif de décollement d'au moins un fromage reposant selon une face inférieure sur une planche, ledit fromage comportant une face supérieure reliée à la face inférieure par une face latérale, comprenant : To achieve these objects as well as others, the invention provides a device for detaching at least one cheese resting on a lower face on a board, said cheese comprising an upper face connected to the lower face by a lateral face, comprising:
- des moyens de bridage, adaptés pour tenir une planche orientée sensiblement dans un premier plan,  - Clamping means adapted to hold a board oriented substantially in a first plane,
- des moyens d'appui destinés à venir contre la face latérale du fromage,  - support means intended to come against the side face of the cheese,
- des premiers moyens de déplacement des moyens d'appui selon une première direction sensiblement parallèle au premier plan ;  first means for moving the support means in a first direction substantially parallel to the first plane;
selon l'invention, le dispositif de décollement comporte des moyens de pilotage adaptés pour déplacer les moyens d'appui de façon à induire un mouvement relatif entre le fromage et la planche selon la première direction. according to the invention, the detachment device comprises control means adapted to move the support means so as to induce a relative movement between the cheese and the board in the first direction.
Un tel dispositif permet un décollement efficace du fromage par l'induction d'un cisaillement dans la zone d'adhérence entre le fromage et la planche. Un tel cisaillement limite efficacement les risques de déformation accidentelle du fromage qui sont encourus lors de l'application d'une traction pure du fromage à l'écart de la planche.  Such a device allows an effective detachment of the cheese by the induction of shear in the area of adhesion between the cheese and the board. Such shear effectively limits the risk of accidental cheese deformation which are incurred when applying pure cheese traction away from the board.
Avantageusement, le dispositif de décollement peut comporter des moyens de réception latéraux du fromage, adaptés pour recevoir le fromage en appui selon sa face latérale.  Advantageously, the detachment device may comprise means for lateral reception of the cheese, adapted to receive the cheese resting along its lateral face.
Les moyens de réception latéraux permettent de limiter le déplacement du fromage, par rapport à la planche, induit par le déplacement des moyens d'appui. On évite ainsi que le fromage ne tombe de la planche.  The lateral receiving means make it possible to limit the movement of the cheese, with respect to the board, induced by the displacement of the support means. This prevents the cheese from falling off the board.
De préférence, les moyens de réception latéraux du fromage peuvent être déplaçables selon la première direction.  Preferably, the lateral receiving means of the cheese may be movable in the first direction.
De tels moyens de réception latéraux permettent, après décollement du fromage, de recentrer celui-ci par rapport à une planche de façon satisfaisante afin que celui-ci repose sur la planche selon toute sa face inférieure. On évite ainsi que le fromage se déforme ensuite sous l'effet de la gravité par un appui seulement partiel de sa face inférieure sur la planche, déformation qui le rendrait impropre à la vente aux consommateurs.  Such lateral receiving means allow, after detachment of the cheese, to refocus it with respect to a board satisfactorily so that it rests on the board along its entire lower face. This avoids the cheese is then deformed under the effect of gravity by only a partial support of its underside on the board, deformation that would make it unfit for sale to consumers.
Avantageusement, les moyens d'appui et/ou les moyens de réception latéraux peuvent venir en contact avec la face latérale du fromage selon une face de contact de forme complémentaire à la forme de la face latérale du fromage.  Advantageously, the bearing means and / or the lateral receiving means may come into contact with the lateral face of the cheese in a contact face of complementary shape to the shape of the lateral face of the cheese.
Une telle complémentarité de forme permet de répartir au mieux les efforts de contact des moyens d'appui et/ou des moyens de réception latéraux avec le fromage et limite ainsi efficacement les risques de déformation du fromage lors de l'actionnement des moyens d'appui et/ou des moyens de réception latéraux. De préférence, les moyens d'appui peuvent, sous l'action de deuxièmes moyens de déplacement, pivoter autour d'un axe orienté selon une deuxième direction perpendiculaire à la première direction et sensiblement parallèle au premier plan, de façon à induire un mouvement relatif entre le fromage et la planche selon une troisième direction sensiblement perpendiculaire au premier plan. Such a complementarity of shape makes it possible to best distribute the contact forces of the support means and / or the lateral receiving means with the cheese and thus effectively limits the risk of deformation of the cheese during the actuation of the support means. and / or lateral receiving means. Preferably, the support means may, under the action of second displacement means, pivot about an axis oriented in a second direction perpendicular to the first direction and substantially parallel to the first plane, so as to induce a relative movement between the cheese and the board in a third direction substantially perpendicular to the foreground.
Les moyens d'appui permettent ainsi une traction partielle du fromage à l'écart de la planche perpendiculairement au plan d'orientation de celle-ci. Un tel mouvement s'avère parfois nécessaire pour amorcer le cisaillement de la zone d'adhérence entre le fromage et la planche lorsqu'un mouvement de translation pure des moyens d'appui selon la première direction est insuffisant.  The support means thus allow partial traction of the cheese away from the board perpendicular to the orientation plane thereof. Such a movement is sometimes necessary to initiate the shearing of the adhesion zone between the cheese and the board when a pure translational movement of the support means in the first direction is insufficient.
De préférence, l'axe de pivotement des moyens d'appui et les deuxièmes moyens de déplacement peuvent être disposés de telle sorte que le pivotement des moyens d'appui induit simultanément un déplacement des moyens d'appui selon la première direction et selon la troisième direction.  Preferably, the pivot axis of the support means and the second displacement means may be arranged so that the pivoting of the support means simultaneously induces a displacement of the support means in the first direction and according to the third direction.
Un tel déplacement des moyens d'appui permet, lors du déplacement des moyens d'appui selon la troisième direction, de presser les moyens d'appui contre la face latérale du fromage grâce au déplacement de ceux-ci selon la première direction.  Such displacement of the support means makes it possible, during the displacement of the support means in the third direction, to press the support means against the lateral face of the cheese by moving the latter along the first direction.
Avantageusement, les moyens d'appui peuvent être en matière plastique.  Advantageously, the support means may be plastic.
Une telle matière est compatible avec les normes d'hygiène applicables aux denrées alimentaires et peut en outre être facilement nettoyée.  Such a material is compatible with the hygiene standards applicable to foodstuffs and can also be easily cleaned.
De préférence, les moyens de déplacement peuvent être pneumatiques. Une telle énergie est compatible avec les normes d'hygiène applicables aux denrées alimentaires et peut en outre être facilement implémentée sur tout site de traitement de fromage à l'aide d'un simple compresseur.  Preferably, the displacement means can be pneumatic. Such energy is compatible with the hygiene standards applicable to foodstuffs and can moreover be easily implemented on any cheese processing site by means of a simple compressor.
De préférence, le dispositif de décollement peut comporter des moyens de détection d'une fin de course des moyens d'appui selon la première direction. Une telle détection de fin de course permet de connaître directement et sans ambiguïté le résultat de l'opération de décollement. Lorsque les moyens d'appui ont effectué leur course de déplacement selon la première direction en intégralité, ce qui est signalé par les moyens de détection de fin de course, alors on sait que l'opération de décollement a convenablement fonctionné. En revanche, lorsque les moyens de détection ne signalent pas un déplacement des moyens d'appui selon l'intégralité de leur course selon la première direction, cela signifie que l'opération de décollement a échoué et que l'intervention manuelle d'un opérateur est nécessaire. Preferably, the detachment device may comprise means for detecting an end of travel of the support means in the first direction. Such end-of-travel detection makes it possible to know directly and without ambiguity the result of the detachment operation. When the support means have carried out their travel in the first direction in full, which is indicated by the end-of-travel detection means, then it is known that the detachment operation has worked properly. On the other hand, when the detection means do not signal a displacement of the support means according to their entire stroke in the first direction, this means that the operation delamination has failed and that manual intervention by an operator is necessary.
De préférence, la première direction peut être inclinée par rapport à un plan horizontal défini comme étant perpendiculaire à une direction verticale selon laquelle s'exerce la gravité terrestre.  Preferably, the first direction may be inclined relative to a horizontal plane defined as being perpendicular to a vertical direction in which the Earth's gravity is exerted.
Une telle inclinaison de la première direction, et donc du premier plan d'orientation de la planche, permet d'utiliser au moins en partie la gravité terrestre pour favoriser le décollement.  Such inclination of the first direction, and therefore the first plane of orientation of the board, allows to use at least part of the Earth's gravity to promote detachment.
Selon un autre aspect, la présente invention propose une machine de traitement d'au moins un fromage reposant selon une face inférieure sur une planche, ladite machine de traitement comprenant au moins un dispositif de décollement tel que décrit précédemment.  According to another aspect, the present invention provides a machine for processing at least one cheese resting on a lower face on a board, said processing machine comprising at least one detachment device as described above.
Selon un autre aspect, la présente invention propose un procédé de décollement d'au moins un fromage reposant selon une face inférieure sur une planche, ledit fromage comportant une face supérieure reliée à la face inférieure par une face latérale ; selon l'invention, le procédé comprend les étapes suivantes : a) fournir un dispositif de décollement ou une machine de traitement tels que décrits précédemment,  According to another aspect, the present invention provides a method of detachment of at least one cheese resting on a lower face on a board, said cheese having an upper face connected to the lower face by a side face; according to the invention, the method comprises the following steps: a) providing a detachment device or a treatment machine as described above,
b) retenir la planche supportant au moins un fromage par les moyens de bridage, ladite planche étant orientée sensiblement dans un premier plan, b) holding the board supporting at least one cheese by the clamping means, said board being oriented substantially in a first plane,
c) déplacer les moyens d'appui selon la première direction de façon à induire un mouvement relatif entre le fromage et la planche selon la première direction. c) moving the support means in the first direction so as to induce a relative movement between the cheese and the board in the first direction.
De préférence, lors de l'étape c), des deuxièmes moyens de déplacement peuvent provoquer un pivotement des moyens d'appui autour d'un axe orienté selon une deuxième direction perpendiculaire à la première direction et sensiblement parallèle au premier plan, de façon à induire un mouvement relatif entre le fromage et la planche selon une troisième direction sensiblement perpendiculaire au premier plan.  Preferably, during step c), second displacement means can cause pivoting of the support means about an axis oriented in a second direction perpendicular to the first direction and substantially parallel to the first plane, so as to inducing a relative movement between the cheese and the board in a third direction substantially perpendicular to the first plane.
De préférence, préalablement à l'étape c), des moyens d'entraînement en rotation peuvent faire pivoter les moyens de bridage de telle sorte que le premier plan d'orientation de la planche se trouve incliné par rapport à un plan horizontal défini comme étant perpendiculaire à une direction verticale selon laquelle s'exerce la gravité terrestre.  Preferably, prior to step c), rotary drive means can rotate the clamping means so that the first plane of orientation of the board is inclined with respect to a horizontal plane defined as being perpendicular to a vertical direction in which Earth's gravity is exercised.
La planche supportant le fromage peut ainsi être introduite dans les moyens de bridage en étant orientée dans un plan sensiblement horizontal puis, après sa retenue dans les moyens de bridage, être inclinée par rapport au plan horizontal afin d'utiliser au moins en partie la gravité pour participer au décollement du fromage. The board supporting the cheese can thus be introduced into the clamping means while being oriented in a substantially horizontal plane and, after its retention in the clamping means, be inclined relative to the plane horizontal to use at least part of gravity to participate in the detachment of cheese.

DESCRIPTION DES MODES DE REALISATION PREFERES  DESCRIPTION OF THE PREFERRED EMBODIMENTS
Les figures 1 à 7 illustrent le fonctionnement d'un mode de réalisation particulier de dispositif de décollement 1 d'un fromage 2 reposant selon une face inférieure 2a sur une planche 3. Le fromage 2 comporte une face supérieure 2b reliée à la face inférieure 2a par une face latérale 2c.  FIGS. 1 to 7 illustrate the operation of a particular embodiment of a detachment device 1 of a cheese 2 resting on a lower face 2a on a board 3. The cheese 2 comprises an upper face 2b connected to the lower face 2a by a side face 2c.
Sur les figures 1 à 7, on distingue des moyens de bridage 4a et 4b adaptés pour tenir la planche 3 orientée sensiblement dans un premier plan P. On distingue également des moyens d'appui 5 destinés à venir en appui contre la face latérale 2c du fromage 2. Des premiers moyens de déplacement 6, commandés par des moyens de pilotage 19, permettent de déplacer les moyens d'appui 5 selon une première direction I-I sensiblement parallèle au premier plan P. Lors de leur déplacement, les moyens d'appui 5 induisent un mouvement relatif entre le fromage 2 et la planche 3 selon la première direction I-I en cisaillant la zone d'adhérence entre la face inférieure 2a du fromage 2 et la planche 3.  FIGS. 1 to 7 distinguish clamping means 4a and 4b adapted to hold the board 3 oriented substantially in a first plane P. There are also support means 5 intended to bear against the lateral face 2c of the cheese 2. First displacement means 6, controlled by control means 19, make it possible to move the support means 5 in a first direction II substantially parallel to the first plane P. During their displacement, the support means 5 induce a relative movement between the cheese 2 and the board 3 in the first direction II by shearing the adhesion zone between the lower face 2a of the cheese 2 and the board 3.
Le dispositif de décollement 1 comporte en outre des moyens de réception latéraux 7 du fromage 2. Les moyens de réception latéraux 7 sont adaptés pour recevoir le fromage 2 en appui selon la face latérale 2c, à l'opposé des moyens d'appui 5.  The detachment device 1 further comprises lateral receiving means 7 of the cheese 2. The lateral receiving means 7 are adapted to receive the cheese 2 resting along the lateral face 2c, opposite to the support means 5.
Les moyens de réception latéraux 7 du fromage 2 sont déplaçables selon la première direction I-I selon un mouvement de translation illustré par la double flèche 8. On voit plus particulièrement sur la figure 8 que les moyens d'appui 5 ont une face de contact 5a de forme complémentaire à la forme de la face latérale 2c du fromage 2. En l'espèce, la face de contact 5a est une surface concave de rayon R1 correspondant sensiblement au rayon R2 du fromage 2 (voir figure 9). Sur la figure 9, les moyens de réception latéraux 7 viennent en contact selon une face de contact 7a de forme complémentaire à la forme de la face latérale 2c du fromage 2. Dans l'exemple illustré, les moyens de réception latéraux 7 comportent trois galets 7b, 7c et 7d autour desquels est enroulée avec du jeu une courroie 7e. Le jeu d'enroulement de la courroie 7e permet à celle-ci de se déformer de telle sorte que la face de contact 7a soit concave selon un rayon R3 sensiblement égal au rayon R2 du fromage 2. The lateral receiving means 7 of the cheese 2 are movable in the first direction II according to a translation movement illustrated by the double arrow 8. It can be seen more particularly in FIG. 8 that the support means 5 have a contact face 5a of complementary shape to the shape of the side face 2c cheese 2. In this case, the contact surface 5a is a concave surface of radius R1 substantially corresponding to the radius R2 cheese 2 (see Figure 9). In FIG. 9, the lateral receiving means 7 come into contact with a contact face 7 a of complementary shape to the shape of the lateral face 2 c of the cheese 2. In the example illustrated, the lateral receiving means 7 comprise three rollers 7b, 7c and 7d around which is wound with play a 7th belt. The winding play of the belt 7e allows it to deform so that the contact face 7a is concave along a radius R3 substantially equal to the radius R2 of the cheese 2.
On voit plus particulièrement sur les figures 2 et 3 que les moyens d'appui 5 peuvent, sous l'action de deuxièmes moyens de déplacement 9 (également commandés par les moyens de pilotage 19 ou par des moyens de pilotage propres), pivoter autour d'un axe 10 orienté selon une deuxième direction II-II perpendiculaire à la première direction I-I et sensiblement parallèle au premier plan P. Le pivotement des moyens d'appui 5 permet d'induire un mouvement relatif entre le fromage 2 et la planche 3 selon une troisième direction III-III sensiblement perpendiculaire au premier plan P. Ce mouvement selon la troisième direction III-III s'applique à la partie du fromage 2 qui est au contact des moyens d'appui 5, produisant une rotation du fromage comme illustré sur les figures 2 et 3.  FIGS. 2 and 3 show more particularly that the support means 5 can, under the action of second moving means 9 (also controlled by the control means 19 or by own driving means), pivot around an axis 10 oriented in a second direction II-II perpendicular to the first direction II and substantially parallel to the first plane P. The pivoting of the support means 5 allows to induce a relative movement between the cheese 2 and the board 3 according to a third direction III-III substantially perpendicular to the first plane P. This movement in the third direction III-III applies to the portion of the cheese 2 which is in contact with the support means 5, producing a rotation of the cheese as illustrated on Figures 2 and 3.
En pratique, les moyens de déplacement 9 comportent un vérin 11 dont la tige 1 1 a est articulée à pivotement sur les moyens d'appui 5 autour d'un axe 12 situé, dans la position de repos des moyens d'appui 5 illustrée sur la figure 2, à une hauteur h en dessous de l'axe 10 selon la troisième direction III-III.  In practice, the displacement means 9 comprise a jack 11 whose rod 11a is articulated pivotally on the support means 5 about an axis 12 located in the rest position of the support means 5 illustrated on Figure 2, at a height h below the axis 10 in the third direction III-III.
Le vérin 1 1 comporte une chambre 1 1 b d'actionnement également articulée à pivotement autour d'un axe 13. Les axes 10, 12 et 13 sont parallèles.  The cylinder 1 1 comprises a chamber 1 1b of actuation also pivotally articulated about an axis 13. The axes 10, 12 and 13 are parallel.
Lorsque le vérin 1 1 est actionné, la tige 1 1 a est déplacée en dehors de la chambre 1 1 b d'actionnement de telle sorte que la longueur totale du vérin 1 1 augmente. Les deuxièmes moyens de déplacement 9 font alors pivoter les moyens d'appui 5 autour de l'axe 10, comme illustré par la figure 3.  When the cylinder 1 1 is actuated, the rod 1 1 a is moved outside the chamber 1 1 b of actuation so that the total length of the cylinder 1 1 increases. The second moving means 9 then rotate the support means 5 around the axis 10, as shown in FIG. 3.
Le pivotement des moyens d'appui 5 se traduit simultanément par un déplacement de ceux-ci selon la première direction I-I et selon la troisième direction III-III de la face de contact 5a. La face de contact 5a est ainsi simultanément pressée contre la face latérale 2c tout en induisant un mouvement de traction du fromage 2 à l'écart de la planche 3 selon la direction III-III pour parvenir à un décollement partiel du fromage 2 tel qu'illustré sur la figure 3.  The pivoting of the support means 5 simultaneously results in a displacement of the latter in the first direction I-I and in the third direction III-III of the contact face 5a. The contact face 5a is thus simultaneously pressed against the side face 2c while inducing a traction movement of the cheese 2 away from the board 3 in the direction III-III to achieve a partial detachment of the cheese 2 such that illustrated in Figure 3.
Afin de faciliter les opérations de nettoyage mais également d'être compatible avec les normes alimentaires en vigueur, les moyens d'appui 5 sont en matière plastique. Egalement pour rester compatible avec les normes alimentaires, les moyens de déplacement 6 et 9 sont pneumatiques. En cas de fuite du fluide d'actionnement (de l'air), il n'y a aucune conséquence pour le fromage 2. In order to facilitate the cleaning operations but also to be compatible with the food standards in force, the support means 5 are made of plastic. Also to remain compatible with food standards, the moving means 6 and 9 are pneumatic. In case of leakage of the actuating fluid (air), there is no consequence for cheese 2.
Afin de s'assurer du bon accomplissement de l'opération de décollement du fromage 2, le dispositif de décollement 1 comporte des moyens de détection de fin de course des moyens d'appui 5 selon la première direction I-I (non représentés).  In order to ensure the smooth completion of the cheese separation operation 2, the detachment device 1 comprises end-of-travel detecting means of the support means 5 in the first direction I-I (not shown).
Afin de profiter au moins partiellement de l'effet de la gravité s'appliquant au fromage 2, la première direction I-I peut être inclinée par rapport à un plan horizontal (non représenté) défini comme étant perpendiculaire à une direction verticale selon laquelle s'exerce la gravité terrestre. En particulier, on pourra concevoir le dispositif de décollement 1 de telle sorte que la première direction I-I est orientée selon la direction verticale définie par la gravité terrestre.  In order to at least partially benefit from the effect of the gravity applying to the cheese 2, the first direction II may be inclined with respect to a horizontal plane (not shown) defined as being perpendicular to a vertical direction according to which Earth's gravity. In particular, we can design the detachment device 1 so that the first direction I-I is oriented in the vertical direction defined by the Earth's gravity.
Les figures 8 à 1 1 illustrent le fonctionnement d'une machine de traitement 14 comprenant cinq dispositifs de décollement 1 a à 1 e similaires au dispositif de décollement 1 illustré sur les figures 1 à 7.  Figures 8 to 1 1 illustrate the operation of a processing machine 14 comprising five peelers 1 to 1 e similar to the detachment device 1 shown in Figures 1 to 7.
Le fonctionnement de la machine de traitement 14 et des dispositifs de décollement 1 , 1 a-1 e va désormais être expliqué plus en détails à l'aide des figures 1 à 1 1.  The operation of the processing machine 14 and the detachment devices 1, 1 a-1 e will now be explained in more detail with the help of Figures 1 to 1 1.
En position initiale, la machine de traitement 14 se trouve comme illustrée sur la figure 8. La machine de traitement 14 est conçue de telle sorte que la première direction I-I est parallèle à la direction verticale IV-IV.  In the initial position, the processing machine 14 is as illustrated in FIG. 8. The processing machine 14 is designed so that the first direction I-I is parallel to the vertical direction IV-IV.
Une planche 3 portant une pluralité de fromages 2 est introduite dans une cavité de réception 15 d'un support mobile 18. Le premier plan P d'orientation de la planche 3 est alors horizontal. La planche 3 est alors retenue par les moyens de bridage 4a et 4b qui viennent serrer la planche 3 entre eux. Le support mobile 18 est rotatif autour d'une direction V-V horizontale.  A board 3 carrying a plurality of cheeses 2 is introduced into a receiving cavity 15 of a mobile support 18. The first plane P of orientation of the board 3 is then horizontal. The board 3 is then retained by the clamping means 4a and 4b which tighten the board 3 between them. The movable support 18 is rotatable about a horizontal V-V direction.
Une fois la planche 3 retenue dans les moyens de bridage 4a et 4b, le support mobile 18 est entraîné en rotation autour de la direction V-V selon une amplitude de 90° pour parvenir dans la position illustrée sur la figure 9 dans laquelle le plan P d'orientation de la planche 3 est sensiblement vertical. Si certains fromages 2 adhèrent à la planche 3, ils restent immobiles par rapport à celle-ci. On se trouve alors dans la configuration illustrée sur la figure 1.  Once the board 3 retained in the clamping means 4a and 4b, the mobile support 18 is rotated about the direction VV by an amplitude of 90 ° to reach the position shown in Figure 9 in which the plane P d Orientation of the board 3 is substantially vertical. If some cheeses 2 adhere to the board 3, they remain motionless relative thereto. We are then in the configuration shown in Figure 1.
Les moyens d'appui 5 sont alors commandés en déplacement par les moyens de pilotage 19 selon la première direction I-I jusqu'à venir au contact de la face latérale 2c des fromages selon la face de contact 5a. Si le cisaillement induit dans la zone d'adhérence entre le fromage 2 et la planche 3 est suffisant, le fromage 2 est alors entraîné par les moyens d'appui 5 jusqu'à venir, en fin de course des moyens d'appui 5, en appui contre la face de contact 7a des moyens de réception latéraux 7. The bearing means 5 are then controlled in displacement by the control means 19 in the first direction II until coming into contact with the side face 2c of the cheeses according to the contact face 5a. If the shear induced in the zone of adhesion between the cheese 2 and the board 3 is sufficient, the cheese 2 is then driven by the support means 5 to come, at the end of the stroke of the support means 5, resting against the contact face 7a of the lateral receiving means 7.
Si le cisaillement induit par le déplacement des moyens d'appui 5 uniquement selon la première direction I-I est insuffisant (c'est-à-dire si les moyens de détection ne signalent pas l'arrivée en fin de course des moyens d'appui 5), les moyens de pilotage 19 peuvent commander un recul des moyens d'appui 5 à l'écart du fromage 2 puis un nouveau déplacement des moyens d'appui 5 contre le fromage 2 selon une force de poussée identique ou augmentée par des moyens de réglage 20.  If the shear induced by the displacement of the support means 5 only in the first direction II is insufficient (that is to say if the detection means do not signal the arrival at the end of the stroke of the support means 5 ), the control means 19 can control a retreat of the support means 5 away from the cheese 2 and then a new displacement of the support means 5 against the cheese 2 according to an identical or increased thrust force by means of setting 20.
Une pluralité de déplacements des moyens d'appui 5 peut être effectuée avec des forces de poussée identiques ou augmentant progressivement. Les moyens de réglage 20 peuvent limiter la force de poussée à un maximum prédéterminé fonction par exemple de la nature du fromage 2 et de la solidité supposée de celui-ci selon sa date d'affinage.  A plurality of displacements of the support means 5 can be performed with identical or progressively increasing thrust forces. The adjustment means 20 can limit the pushing force to a predetermined maximum, for example depending on the nature of the cheese 2 and the supposed strength of the latter according to its ripening date.
En alternative ou en complément, si le cisaillement induit par le déplacement des moyens d'appui 5 uniquement selon la première direction I-I est insuffisant (c'est-à-dire si les moyens de détection ne signalent pas l'arrivée en fin de course des moyens d'appui 5), il peut être nécessaire que les moyens de pilotage 19 actionnent les deuxièmes moyens de déplacement 9 (vérin 11 ) pour provoquer un pivotement des moyens d'appui 5 autour de l'axe 10 de façon à amorcer le cisaillement de la zone d'adhérence entre le fromage 2 et la planche 3 par un léger décollement, comme illustré sur la figure 3.  In alternative or in addition, if the shear induced by the displacement of the support means 5 only in the first direction II is insufficient (that is to say if the detection means do not signal the arrival at the end of the race support means 5), it may be necessary for the control means 19 to actuate the second moving means 9 (ram 11) to cause the support means 5 to pivot about the axis 10 so as to initiate the shearing of the zone of adhesion between the cheese 2 and the board 3 by a slight detachment, as illustrated in FIG.
La face inférieure 2a n'adhérant plus à la planche 3, le déplacement des moyens d'appui 5 et du fromage 2 selon la première direction I-I se poursuit jusqu'à parvenir dans la position illustrée sur la figure 4 sur laquelle le fromage 2 vient en contact selon sa face latérale 2c avec la face de contact 7a des moyens de réception latéraux 7.  The lower face 2a no longer adhering to the board 3, the displacement of the support means 5 and the cheese 2 in the first direction II continues to reach the position illustrated in Figure 4 on which the cheese 2 comes in contact along its side face 2c with the contact face 7a of the lateral receiving means 7.
Si les moyens de détection ne signalent toujours pas d'arrivée en fin de course des moyens d'appui 5 malgré le pivotement des moyens d'appui 5, un signal est généré pour demander l'intervention manuelle d'un opérateur.  If the detection means still do not signal arrival at the end of the support means 5 despite the pivoting of the support means 5, a signal is generated to request the manual intervention of an operator.
Après décollement du fromage 2, les moyens de pilotage 19 commandent les premiers et deuxièmes moyens de déplacement 6 et 9 de façon inverse pour revenir à la position illustrée sur la figure 5 sur laquelle le dispositif de décollement 1 est revenu dans la position initiale qu'il occupait sur la figure 1. La position illustrée sur la figure 5 correspond à la position de la machine de traitement 14 illustrée sur la figure 1 1. After detachment of the cheese 2, the control means 19 control the first and second moving means 6 and 9 in a reverse manner to return to the position shown in Figure 5 in which the detachment device 1 is returned to the initial position that he occupied in Figure 1. The The position illustrated in FIG. 5 corresponds to the position of the processing machine 14 illustrated in FIG.
Dans le cas de la machine de traitement 14 illustré sur les figures 8 à 1 1 , le propre poids du fromage 2 contribue au décollement du fromage 2 de la planche 3 et le fait chuter en direction des moyens de réception latéraux 7.  In the case of the processing machine 14 illustrated in FIGS. 8 to 11, the own weight of the cheese 2 contributes to the detachment of the cheese 2 from the board 3 and causes it to fall towards the lateral receiving means 7.
Après décollement du fromage 2 vis-à-vis de la planche 3, il est possible de traiter le fromage, par exemple par brossage, lavage, salage, il est également possible de traiter la planche 3, de la retirer, d'insérer une autre planche, de retourner le support mobile 18 pour poser le fromage 2 sur une autre planche selon son autre face 2b.  After detaching the cheese 2 vis-à-vis the board 3, it is possible to treat the cheese, for example by brushing, washing, salting, it is also possible to treat the board 3, remove it, insert a another board, turn the mobile support 18 to put the cheese 2 on another board according to its other side 2b.
A partir des positions illustrées sur les figures 5 et 10, il est nécessaire de recentrer le fromage 2 par rapport à la planche 3 de façon que celui-ci repose selon toute sa face inférieure 2a sur la planche 3. Pour ce faire, les moyens de réception latéraux sont déplacés selon un mouvement illustré par la flèche 16 jusqu'à parvenir dans la position illustrée sur les figures 6 et 1 1 dans lesquelles le fromage 2 est parfaitement centré sur la planche 3.  From the positions illustrated in Figures 5 and 10, it is necessary to refocus the cheese 2 relative to the board 3 so that it rests in its entire lower face 2a on the board 3. To do this, the means side receiving means are moved in a movement illustrated by the arrow 16 to reach the position shown in Figures 6 and 1 1 in which the cheese 2 is perfectly centered on the board 3.
Si dans la position illustrée sur les figures 6 et 1 1 la planche 3 est orientée dans un plan sensiblement horizontal, la planche 3 portant les fromages 2 peut être retirée de la cavité de réception 15 après que les moyens de réception latéraux 7 aient été à nouveau déplacés à l'écart des fromages 2 selon un mouvement illustré par la flèche 17 (figure 6) pour parvenir à la position illustrée sur la figure 7.  If in the position illustrated in Figures 6 and 1 1 the board 3 is oriented in a substantially horizontal plane, the board 3 bearing the cheese 2 can be removed from the receiving cavity 15 after the lateral receiving means 7 have been to moved again away from the cheeses 2 in a movement illustrated by the arrow 17 (Figure 6) to reach the position illustrated in Figure 7.
Dans le cas de la machine de traitement 14 illustrée sur les figures 8 à 1 1 , la planche 3 se trouve, dans la position illustrée sur les figures 6 et 1 1 , orientée dans un plan sensiblement vertical. Il est alors nécessaire de faire pivoter le support mobile 18 autour de la direction V-V selon une amplitude permettant de ramener la planche 3 dans une orientation sensiblement horizontale de son premier plan P et dans laquelle elle supporte les fromages 2. Les moyens de réception latéraux 7 peuvent alors être déplacés à l'écart des fromages 2 (flèche 17), puis la planche 3 peut être retirée de la cavité de réception 15 sans risque de faire tomber les fromages 2.  In the case of the processing machine 14 illustrated in Figures 8 to 1 1, the board 3 is, in the position illustrated in Figures 6 and 1 1, oriented in a substantially vertical plane. It is then necessary to rotate the mobile support 18 around the direction VV by an amplitude allowing to bring the board 3 in a substantially horizontal orientation of its first plane P and in which it supports the cheese 2. The lateral receiving means 7 can then be moved away from the cheese 2 (arrow 17), then the board 3 can be removed from the receiving cavity 15 without the risk of falling cheese 2.
Dans la description qui précède, le terme « planche » entend désigner tout type de support adapté pour porter au moins un fromage 2, de n'importe quelles taille, forme et matière.  In the foregoing description, the term "board" means any type of support adapted to carry at least one cheese 2, of any size, shape and material.
La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.  The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof within the scope of the claims below.
