Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention est relative à une installation de découpe de produits alimentaires qui se présentent sous la forme de pains allongés, autrement appelés barres.The present invention relates to a food cutting plant which is in the form of elongated breads, otherwise called bars.

Il peut s'agir de produits carnés tels que du saucisson, du jambon, du bacon, ou encore de fromage ou de produits d'origine végétale (tronçon d'ananas par exemple).It may be meat products such as sausage, ham, bacon, or cheese or products of plant origin (eg pineapple).

Dans l'ensemble de la présente demande, on entend par "pain allongé" non seulement un pain monolithique, c'est à dire constitué d'une seule et même pièce de produit alimentaire, mais également un "entassement" de plusieurs blocs de produits alimentaires qui n'ont pas de réelle cohésion mécanique entre eux, l'ensemble ayant globalement l'aspect d'un pain.Throughout the present application, the term "elongated bread" not only a monolithic bread, ie consisting of a single piece of food product, but also a "stack" of several blocks of products food which does not have a real mechanical cohesion between them, the whole having generally the appearance of a bread.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

On décrit dans le document FR-A-3047433 , au nom du présent demandeur, une installation de ce genre, qui fait usage de goulottes (magasins) dans lesquelles sont introduits les pains en vue de leur découpe.We describe in the document FR-A-3047433 , on behalf of the present applicant, an installation of this kind, which makes use of chutes (stores) in which are introduced the breads for their cutting.

Plus généralement, ce type de dispositif permet, pour autant que l'on ait prévu plusieurs magasins disposés côte à côte, de découper simultanément plusieurs portions de produit alimentaire, de manière ordonnée, à un endroit déterminé, de sorte que ces portions se répartissent dans des réceptacles qui défilent sous le dispositif, véhiculés par exemple par un tapis mobile, ou sont déposées directement sur le convoyeur défilant en dessous. Dans d'autres applications, les portions se répartissent sur des pizzas ou sur des tranches de pain (constitutives de sandwiches, de cordons bleus, etc.) qui sont déplacées par un convoyeur.More generally, this type of device makes it possible, provided that several stores arranged side by side are provided, to simultaneously cut several portions of food product, in an orderly manner, at a given location, so that these portions are distributed in receptacles that run under the device, for example conveyed by a moving belt, or are deposited directly on the conveyor running underneath. In other applications, the portions are distributed over pizzas or slices of bread (consisting of sandwiches, blue cords, etc.) which are moved by a conveyor.

Par ailleurs, dans un processus de transformation de produits alimentaires, on peut être amené à déposer, en rangées ordonnées, des portions de viande sur un convoyeur destiné à transférer les produits vers un poste de traitement, par exemple de surgélation, de cuisson ou de refroidissement.Furthermore, in a food processing process, it may be necessary to deposit, in ordered rows, portions of meat on a conveyor for transferring the products to a treatment station, for example freezing, cooking or cooking. cooling.

De même, il est courant, dans le domaine de l'industrie agro-alimentaire, d'utiliser ce type de "trancheurs" pour des opérations d'assemblage de différentes tranches pour constituer le produit final. Ainsi, les croque-monsieur ou les petits sandwiches que l'on appelle "buns" sont constitués de plusieurs éléments tels que du pain, du jambon et du fromage. Ces opérations se font à la volée par détection du produit, coupe et dépôt de l'élément suivant sur un support tel qu'un réceptacle défilant sous l'appareil ou directement sur une tranche de pain.Similarly, it is common in the field of the food industry, to use this type of "slicers" for assembly operations of different slices to form the final product. Thus, croque-monsieur or small sandwiches that are called "buns" consist of several elements such as bread, ham and cheese. These operations are done on the fly by detecting the product, cut and deposit the next element on a support such as a receptacle running under the device or directly on a slice of bread.

On peut citer également la situation dans laquelle on découpe un grand nombre de tranches de viande, par exemple de bacon, lesquelles sont acheminées par un convoyeur vers un four.There is also the situation in which a large number of slices of meat, for example bacon, are cut out and conveyed by a conveyor to an oven.

Principalement pour des raisons d'augmentation de cadence, on a multiplié ce genre de dispositifs, de manière à augmenter le nombre de lignes travaillant de concert.Mainly for reasons of increase of pace, we have multiplied this kind of devices, so as to increase the number of lines working together.

Toutefois, cela nécessite la mise en place simultanée de plusieurs pains de produits alimentaires, dans les goulottes qui sont positionnées verticalement et animées d'un mouvement de va et vient en vue de la découpe de tranches. En effet, on cherche, autant que possible, que le tranchage ait lieu en continu, ce qui nécessite un réapprovisionnement continuel des goulottes.However, this requires the simultaneous introduction of several breads of food products, in the chutes which are positioned vertically and moved back and forth for cutting slices. Indeed, we seek, as much as possible, the slicing takes place continuously, which requires a continuous replenishment of the chutes.

Pour des raisons d'encombrement, l'extrémité supérieure ouverte des goulottes par laquelle on introduit le pain à découper est disposée en hauteur, de sorte que des opérateurs y ont accès via au moins une plate-forme desservie par un escalier.For reasons of space, the open top end of the chutes by which the bread is cut is arranged in height, so that operators have access via at least one platform served by a staircase.

Du fait du grand nombre d'allers-retours entre le sol sur lequel sont regroupées et stockées les palettes de pains à découper et le niveau de chargement dans les goulottes, le risque de chutes des opérateurs dans l'escalier de la plate-forme est élevé.Due to the large number of round trips between the floor on which the pallets of slicing bread and the level of loading in the chutes are grouped and stored, the risk of operators falling down the platform stairs is high.

Par ailleurs, le poids individuel de chaque pain de produit peut être compris entre 10 et 20 kg, ce qui conduit les opérateurs à porter les pains dans leurs bras, horizontalement, à l'unité ou au maximum par 2, entre le sol et le niveau supérieur de la passerelle de chargement, en empruntant l'escalier.Moreover, the individual weight of each product bread can be between 10 and 20 kg, which leads the operators to carry the breads in their arms, horizontally, to the unit or at most by 2, between the ground and the upper level of the loading bridge, taking the stairs.

Le chargement dans les goulottes nécessite alors une levée rapide et une rotation de chaque barre, synchrone avec le mouvement de balancier ou linéaire de la goulotte à charger. Ces mouvements fastidieux, répétitifs et rapides induisent notamment des risques de blessure, tout particulièrement du dos.Loading in the chutes then requires rapid lifting and rotation of each bar, synchronous with the pendulum or linear movement of the chute to be loaded. These tedious, repetitive and rapid movements induce particular risks of injury, especially the back.

De plus, la technologie de ces machines nécessite un niveau de chargement homogène entre les différentes goulottes. Il ne peut être respecté pour des raisons évidentes d'impossibilité pour un opérateur de recharger rapidement plusieurs goulottes en même temps. Cela conduit de ce fait rapidement à une différence de qualité dans le tranchage et le dépôt des produits tranchés entre les différentes lignes.In addition, the technology of these machines requires a level of homogeneous loading between the different chutes. It can not be respected for obvious reasons of impossibility for an operator to quickly recharge several chutes at the same time. This quickly leads to a difference in quality in the slicing and deposition of sliced products between the different lines.

Un état de la technique supplémentaire est constitué par les documents EP 1935590 et EP 1854596 .An additional state of the art consists of the documents EP 1935590 and EP 1854596 .

La présente invention a justement pour but de pallier ces inconvénients et vise notamment à améliorer l'installation décrite dans le document précité FR-A-3047433 .The purpose of the present invention is precisely to overcome these disadvantages and aims in particular to improve the installation described in the aforementioned document. FR-A-3047433 .

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

Ainsi, la présente invention se rapporte à une installation de découpe de produits alimentaires qui se présentent sous la forme de pains allongés et qui comporte :

  • au moins un ensemble comprenant au moins une goulotte ou magasin de réception d'un pain de produit alimentaire, cette goulotte ayant la forme d'un compartiment allongé, généralement dirigé de haut en bas, et configurée pour recevoir ledit pain par son extrémité supérieure ouverte, avec possibilité de coulissement, de manière à le diriger vers et au-delà de son extrémité inférieure ouverte, sous l'effet de son propre poids ;
  • un plateau généralement horizontal, disposé à distance de l'extrémité inférieure de ladite goulotte, et une lame de coupe disposée au voisinage de ce plateau ;
  • des moyens de déplacement dudit ensemble conformés pour amener alternativement ladite extrémité inférieure au voisinage dudit plateau de manière à ce que ladite lame interfère avec ledit pain et procède à son découpage,
caractérisée par le fait qu'elle comporte d'une part, une unité de stockage de pains alimentaires et d'autre part, des moyens mécanisés et/ou automatisés de prélèvement d'au moins un pain dans ladite unité de stockage et de transfert puis de chargement dans ladite goulotte, par son extrémité supérieure ouverte, et que :
  • ladite unité comprend un ou plusieurs plateaux superposés formant une pile ;
  • elle comporte des moyens conformés pour que le plateau le plus haut sur lequel sont présents des pains occupe toujours un niveau constant ;
  • elle comporte au moins un organe de poussée tel qu'un vérin conformé pour évacuer lesdits pains présents sur le plateau le plus haut ;
  • ainsi qu'un réceptacle mobile entre une position de chargement dans laquelle il reçoit au moins un pain évacué par ledit au moins un organe de poussée, et une position de transfert dans laquelle ledit réceptacle est positionné en regard de ladite goulotte, au voisinage immédiat de son extrémité supérieure ouverte.
Thus, the present invention relates to a food product cutting plant which is in the form of elongated breads and which comprises:
  • at least one assembly comprising at least one trough or receiving tray for a food product roll, this trough having the shape of an elongated compartment, generally directed from top to bottom, and configured to receive said bread by its open upper end with the possibility of sliding so as to direct it towards and beyond its open lower end, under the effect of its own weight;
  • a generally horizontal plate, disposed at a distance from the lower end of said chute, and a cutting blade disposed in the vicinity of this plate;
  • displacement means of said assembly shaped to alternately bring said lower end into the vicinity of said plate so that said blade interferes with said bread and proceeds to cutting,
characterized in that it comprises, on the one hand, a bread roll storage unit and, on the other hand, mechanized and / or automated means for taking at least one bread from said storage and transfer unit, and loading in said chute, by its open upper end, and that:
  • said unit comprises one or more stacked trays forming a stack;
  • it comprises means shaped so that the highest plateau on which are present loaves always occupies a constant level;
  • it comprises at least one thrust member such as a jack shaped to evacuate said loaves present on the uppermost plate;
  • and a movable receptacle between a loading position in which it receives at least one bread evacuated by said at least one pushing member, and a transfer position in which said receptacle is positioned opposite said chute, in the immediate vicinity of its upper end open.

Grâce à cet ensemble de caractéristiques, les opérateurs n'ont plus à se déplacer et à porter des charges lourdes, ce qui diminue drastiquement le risque de chute et de blessure. Ils peuvent ainsi se concentrer sur l'approvisionnement de l'unité de stockage, surveiller le bon fonctionnement global de l'installation et intervenir rapidement en cas de besoin.With this set of features, operators no longer have to move and carry heavy loads, which drastically reduces the risk of falling and injury. They can focus on supplying the storage unit, monitor the overall operation of the plant and respond quickly when needed.

De même, la mise en place de ces dispositifs conduit à une augmentation substantielle de la qualité du tranchage et du dépôt des tranches.Similarly, the implementation of these devices leads to a substantial increase in the quality of slicing and slab deposition.

Selon d'autres caractéristiques non limitatives et avantageuses de l'invention :

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En se reportant aux figures 1 à 4 annexées, on a affaire à une installation I de découpe de produits alimentaires qui se présentent sous la forme de pains allongés P, installation qui comporte un ensemble E constitué d'une série de goulottes 1 (encore appelé magasin de réception d'un pain de produit alimentaire).Referring to Figures 1 to 4 attached, we are dealing with a facility I for cutting food products which are in the form of elongated breads P, which installation comprises a set E consisting of a series of chutes 1 (also called a store receiving a bread of foodstuff).

Dans l'exemple représenté ici, ces goulottes 1 sont au nombre de cinq. Bien entendu, ce nombre peut être différent, par exemple inférieur ou supérieur. Cet ensemble présente donc la particularité d'être composé de goulottes individuelles qui sont juxtaposées, de sorte que ledit ensemble présente une largeur globale optimisée, qui est sensiblement égale à celle d'un convoyeur sans fin mobile, non représenté sur les figures précitées mais dont l'axe longitudinal X-X' apparaît à la figure 1.In the example shown here, these chutes 1 are five in number. Of course, this number may be different, for example lower or higher. This assembly therefore has the particularity of being composed of individual chutes which are juxtaposed, so that said assembly has an optimized overall width, which is substantially equal to that of a mobile endless conveyor, not shown in the figures above but of which the longitudinal axis XX 'appears at the figure 1 .

Cet ensemble E de goulottes 1 est monté sur un bâti massif 10 de type connu, de sorte que l'ouverture supérieure 11 de chacune d'elles se trouve largement surélevée par rapport au sol.This set E trunking 1 is mounted on a solid frame 10 of known type, so that the upper opening 11 of each of them is largely raised above the ground.

Bien que cela ne soit pas visible sur les figures précitées, le bâti 10 intègre des moyens qui permettent aux goulottes 1 d'être déplacées selon un mouvement alternatif, soit strictement linéaire, soit de balancier, de manière à rapprocher périodiquement leur extrémité inférieure, et par là même l'extrémité inférieure d'un pain P de produit alimentaire engagé dans chacune des goulottes1 à proximité d'une lame de coupe disposée au niveau d'un plateau horizontal qui s'étend sous les goulottes.Although this is not visible in the aforementioned figures, the frame 10 incorporates means that allow the chutes 1 to be moved in an alternating movement, either strictly linear or rocker, so as to periodically bring their lower end, and thereby the lower end of a bread P of food product engaged in each of the chutes1 near a cutting blade disposed at a horizontal plate which extends under the troughs.

On peut se reporter si nécessaire au document FR 3 047 433 qui a été cité en introduction de la présente demande pour plus d'explications sur la structure et le fonctionnement d'un exemple d'un tel ensemble.If necessary, refer to the document FR 3,047,433 which has been cited in the introduction of the present application for further explanation on the structure and operation of an example of such a set.

Le mouvement alternatif évoqué plus haut, reproduit un certain nombre de fois, permet de découper chacun des pains en un nombre élevé de tranches de produit alimentaire. Ces tranches tombent soit directement sur le convoyeur précité, soit dans des récipients préalablement déposés sur le convoyeur, ou directement sur des préparations alimentaires telles que des pizzas déplacées les unes derrière les autres par ledit convoyeur.The reciprocating movement mentioned above, reproduced a number of times, makes it possible to cut each of the loaves into a large number of slices of food product. These slices fall either directly on the aforementioned conveyor, or in containers previously deposited on the conveyor, or directly on food preparations such as pizzas moved one behind the other by said conveyor.

L'expérience a montré que le dépôt de ces tranches se fait de manière très régulière et uniforme tant qu'environ un tiers du pain P est encore présent dans chaque goulotte. Dans ces conditions, on comprend qu'il est préférable, voire impératif de se préparer à introduire un nouveau pain P dans chaque goulotte dès lors qu'il ne reste dans chaque goulotte qu'un tiers du pain initial. Et cette manipulation doit être répétée pour chaque goulotte, en un minimum de temps, de manière à obtenir des découpes uniformes indépendamment des goulottes.Experience has shown that the deposition of these slices is very regular and uniform as long as about a third of the bread P is still present in each chute. Under these conditions, we understand that it is preferable, even imperative to prepare to introduce a new bread P in each chute as long as there is only one third of the original bread left in each chute. And this manipulation must be repeated for each chute, in a minimum of time, so as to obtain uniform cuts independently of the chutes.

Avantageusement, la détection de la présence de seulement un tiers de pain restant dans la goulotte peut être effectuée par au moins un détecteur.Advantageously, detection of the presence of only one third of bread remaining in the chute can be performed by at least one detector.

En pratique, l'introduction d'un pain P dans une goulotte 1, qui est effectuée alors que l'installation I est en fonctionnement, est réalisée lors d'une phase particulière du mouvement alternatif de la goulotte, à savoir la phase dans laquelle son extrémité supérieure ouverte est la plus proche de l'opérateur, ceci pour un confort de travail.In practice, the introduction of a bread P in a chute 1, which is carried out while the installation I is in operation, is performed during a particular phase of the reciprocating movement of the chute, namely the phase in which its open upper end is the closest to the operator, this for working comfort.

Dans l'exemple de réalisation représenté ici, l'installation I comporte une plate-forme 2 à laquelle on accède par un escalier 20 et qui permet à des opérateurs d'avoir un accès à l'ouverture supérieure 11 des goulottes 1 par le dessus de celles-ci, de manière à faciliter l'introduction des pains P.In the embodiment shown here, the installation I comprises a platform 2 which is accessed by a staircase 20 and which allows operators to have access to the upper opening 11 of the troughs 1 from above. of these, so as to facilitate the introduction of breads P.

La plate-forme 2 s'étend parallèlement au bâti 10 de l'ensemble E, c'est-à-dire selon une direction généralement perpendiculaire à l'axe X-X' précité. Par ailleurs et comme le montrent les figures, la plate-forme 2 jouxte l'ensemble E de manière à ce qu'un de ses bords longitudinaux soit au plus près de l'ouverture supérieure 11 des goulottes 1.The platform 2 extends parallel to the frame 10 of the assembly E, that is to say in a direction generally perpendicular to the axis X-X 'supra. Moreover and as shown in the figures, the platform 2 adjoins the assembly E so that one of its longitudinal edges is closer to the upper opening 11 of the troughs 1.

Essentiellement pour des raisons de sécurité, la plate-forme 2 est pourvue de deux garde-corps 21 dont la barre supérieure horizontale est référencée 210. Cela permet à des opérateurs présents sur la plate-forme de se pencher, tout particulièrement au-dessus de l'ensemble E, sans craindre pour leur sécurité.Essentially for safety reasons, the platform 2 is provided with two guardrails 21 whose horizontal upper bar is referenced 210. This allows operators on the platform to lean, especially above set E, without fear for their safety.

Par ailleurs et comme on l'expliquera plus loin dans la description, ces barres supérieures 210 ont une fonction supplémentaire, à savoir qu'elles constituent des chemins de guidage pour un réceptacle de réception et de transfert de pains alimentaires.Furthermore and as will be explained later in the description, these upper bars 210 have an additional function, namely that they constitute guide paths for a receptacle for receiving and transferring breads.

De plus, l'installation représentée sur les figures précitées présente des moyens S de stockage de pains destinés à approvisionner les goulottes 1 décrites plus haut.In addition, the installation shown in the figures above has bread storage means S for supplying the chutes 1 described above.

Ces moyens sont disposés à l'extrémité de la plate-forme 2 qui est opposée à l'escalier 20.These means are arranged at the end of the platform 2 which is opposite the staircase 20.

Ils comprennent un dispositif de stockage et d'élévation à niveau constant 3 qui comprend essentiellement un cadre parallélépipédique 30 à claire-voie et d'orientation verticale, qui est conformé pour recevoir sélectivement un chariot de stockage 4 dans lequel sont placés préalablement, sur des plateaux 40 superposés, des ensembles de pains P de produits alimentaires.They comprise a constant-level storage and elevation device 3 which essentially comprises a parallelepipedal frame 30 with a vertical orientation, which is shaped to selectively receive a storage trolley 4 in which are previously placed on trays 40 superimposed, sets of breads P of food products.

Ainsi, un chariot 4 sur lequel sont déjà placés des pains P est amené à être déplacé manuellement par un opérateur ou automatiquement à l'aide d'un engin adapté, à l'intérieur du cadre 30 via une ouverture latérale, comme le montre la flèche f représentée à la figure 1.Thus, a carriage 4 on which loaves P are already placed is caused to be moved manually by an operator or automatically by means of a suitable machine, inside the frame 30 via a lateral opening, as shown in FIG. arrow f represented in the figure 1 .

Par ailleurs, le cadre 30 intègre des moyens (non représentés) qui permettent de maintenir à niveau constant, c'est à dire à la même hauteur, le plateau 40 le plus haut du chariot encore garni de pains P.Furthermore, the frame 30 includes means (not shown) which allow to maintain at constant level, that is to say at the same height, the upper tray 40 of the carriage still topped with breads P.

En d'autres termes, quand un chariot 4 dont tous les plateaux 40 sont garnis de pains P voit son plateau supérieur débarrassé des pains P qu'il accueillait, alors le dispositif 3 est actionné afin que le plateau situé immédiatement en dessous soit positionné à la même hauteur que le plateau précédent, et ainsi de suite.In other words, when a carriage 4 of which all the trays 40 are lined with rolls P sees its upper tray cleared of the rolls P which it accommodates, then the device 3 is actuated so that the tray situated immediately below is positioned at the same height as the previous plateau, and so on.

Cette mise à niveau toujours à une hauteur constante est par exemple déclenché via un capteur qui détecte l'absence de pains sur un plateau déterminé et commande le pilotage du relevage du chariot de manière à ce que le plateau garni disposé immédiatement en dessous soit amené au niveau adéquat. En l'occurrence, ce niveau "constant" correspond sensiblement à celui de la face supérieure des barres 210 des garde-corps 21. L'opération de relevage est par exemple effectuée par un système de convoyage et levage à chaînes ou de tout autre dispositif assurant la même fonction.This leveling always at a constant height is for example triggered via a sensor which detects the absence of loaves on a given plateau and controls the steering of the lift of the truck so that the packed tray immediately below is brought to adequate level. In this case, this "constant" level corresponds substantially to that of the upper face of the bars 210 of the guardrails 21. The lifting operation is for example carried out by a conveyor system and chain hoist or any other device providing the same function.

Lorsqu'un chariot 4 est vide, c'est-à-dire lorsque l'ensemble de ces plateaux 40 sont débarrassés de leurs pains P, alors ce chariot est extrait du cadre 30 par son extrémité opposée, comme le montre la flèche g de la figure 1.When a carriage 4 is empty, that is to say when all of these trays 40 are freed of their rolls P, then this carriage is extracted from the frame 30 by its opposite end, as shown by the arrow g of the figure 1 .

Comme cela est particulièrement visible à la figure 1, le dispositif 3 intègre aussi des moyens de prélèvement 5 d'au moins un pain P présent au niveau le plateau supérieur 40 du chariot.As is particularly visible in the figure 1 , the device 3 also includes sampling means 5 of at least one bread P present at the upper plate 40 of the carriage.

A cet effet, le cadre 30 précité est équipé ici de moyens 5 constitués d'une paire de vérins parallèles et horizontaux 50. Un poussoir commun 51, fixé à l'extrémité libre de la tige des vérins 5, est orienté parallèlement aux pains P en place sur le chariot 4.For this purpose, the aforementioned frame 30 is equipped here with means 5 consisting of a pair of parallel and horizontal cylinders 50. A common pusher 51, fixed to the free end of the rod of the cylinders 5, is oriented parallel to the P breads in place on the trolley 4.

Les moyens 5 s'étendent à une hauteur telle que, lorsque la tige des vérins est en position d'extension, le poussoir 51 déplace les pains P en place sur le plateau 40 le plus haut.The means 5 extend to a height such that, when the rod of the cylinders is in the extended position, the pusher 51 moves the loaves P in place on the top plate 40.

Bien entendu, l'actionnement de ces vérins ne fait que sur commande, c'est à dire lorsque les goulottes 1 nécessitent d'être réapprovisionnées en pains P. Cet actionnement est de préférence piloté automatiquement dès lors que le capteur dont il a été fait état plus haut a détecté seulement la présence d'un tiers de pain dans la goulotte concernée.Of course, the actuation of these cylinders is only on command, that is to say when the chutes 1 need to be replenished breads P. This operation is preferably controlled automatically when the sensor which was made state above has detected only the presence of a third of bread in the chute concerned.

Sur commande spécifique, ces vérins sont pilotés de manière à ce que la plaque 51 soit déplacée vers l'intérieur du dispositif 3 et interfère, c'est-à-dire pousse le pain P le plus proche présent sur le plateau le plus haut du dispositif 3 de manière à déplacer soit un soit l'ensemble de ces pains en direction de la plate-forme 2.On specific order, these cylinders are controlled so that the plate 51 is moved towards the inside of the device 3 and interferes, that is to say pushes the nearest bread P present on the highest tray of the device 3 so as to move either one or all of these loaves in the direction of the platform 2.

Toujours dans le cadre de ce mode de réalisation particulier, l'installation comporte également des moyens de transfert de pains vers l'une ou l'autre des goulottes 1 précitées.Still in the context of this particular embodiment, the installation also includes means for transferring bread to one or the other of the aforementioned chutes 1.

Ces moyens de transfert consistent en un réceptacle 6, plus particulièrement visible à la figure 4, lequel est déplacé sélectivement le long des chemins de guidage constitués par la face supérieure des barres 210 des garde-corps 21.These transfer means consist of a receptacle 6, more particularly visible at the figure 4 which is selectively moved along the guide tracks formed by the upper face of the bars 210 of the guardrails 21.

Le réceptacle est également visible aux figures 1 à 3, 5 et 6. Il est représenté très schématiquement, seulement afin d'en comprendre la fonction.The receptacle is also visible to Figures 1 to 3 , 5 and 6 . It is represented very schematically, only in order to understand its function.

Ce réceptacle 6 a une forme allongée. Il s'étend horizontalement et parallèlement au convoyeur précité. Il prend donc appui sur la face supérieure des barres 210 des garde-corps 21 par des galets ou roues 60 et est piloté par des moyens automoteurs non représentés ici. Il est ouvert sur le côté et vers le haut, de manière à pouvoir réceptionner au moins un pain P qui a été préalablement évacué d'un plateau 4 par le poussoir 51. De préférence, ce réceptacle est légèrement creusé pour recevoir et immobiliser ledit pain P.This receptacle 6 has an elongated shape. It extends horizontally and parallel to the aforementioned conveyor. It therefore bears on the upper face of the bars 210 of the railings 21 by rollers or wheels 60 and is driven by self-propelled means not shown here. It is open on the side and upwards, so as to be able to receive at least one bread P which has been previously removed from a tray 4 by the pusher 51. Preferably, this receptacle is slightly hollowed to receive and immobilize said bread P.

Dans ces conditions, ce réceptacle 6 est positionné en position d'attente, non opérationnelle, à l'extrémité de la plate-forme 2, au plus près du dispositif 3, comme le montrent les figures 1 et 2.Under these conditions, this receptacle 6 is positioned in the non-operative waiting position at the end of the platform 2, as close as possible to the device 3, as shown by FIGS. figures 1 and 2 .

L'installation comprend des moyens de pilotage de ce réceptacle qui sont conçus pour le déplacer automatiquement sur une course juste suffisante pour qu'il aille se positionner en regard de la goulotte 1 à approvisionner en pain P. Ainsi, quand on considère la situation de la figure 4, ce réceptacle a été déplacé en vis-à-vis de la troisième goulotte 1, en vue d'y introduire le pain P qu'il transporte.The installation comprises means of control of this receptacle which are designed to move it automatically on a race just sufficient for it to be positioned next to the chute 1 to supply bread P. Thus, when we consider the situation of the figure 4 , this receptacle has been moved vis-à-vis the third chute 1, to introduce the bread P he carries.

Pour permettre cette introduction, le réceptacle 6 est équipé de moyens d'évacuation 7 du pain P. Ces moyens comprennent un vérin 70 disposé horizontalement et au-dessus du réceptacle proprement et qui est couplé à une palette 71 disposée à l'extrémité d'une tige d'actionnement 72, l'activation dudit vérin 70 se traduisant par un déplacement linéaire de la palette 71 en direction de la goulotte associée 1.To allow this introduction, the receptacle 6 is equipped with evacuation means 7 of the bread P. These means comprise a jack 70 arranged horizontally and above the receptacle properly and which is coupled to a pallet 71 disposed at the end of an actuating rod 72, the activation of said jack 70 resulting in a linear displacement of the pallet 71 towards the associated chute 1.

On passe ainsi de la position non active de la figure 5 à la position active de la figure 6.We thus move from the inactive position of the figure 5 at the active position of the figure 6 .

Dans l'installation I présentée ici, les goulottes 1, bien que d'orientation généralement verticale, présentent une ouverture supérieure 11 largement évasée et orientée vers le réceptacle, avec un rebord 110 dirigé presqu'à l'horizontale.In the installation I presented here, the troughs 1, although of generally vertical orientation, have an upper opening 11 widely flared and oriented towards the receptacle, with a flange 110 directed almost horizontally.

Dans ces conditions, en déplaçant la palette 71 précitée via le vérin 70, il est possible et aisé de déplacer le pain P pour le diriger directement dans l'ouverture 11 de la goulotte, ainsi que le montre la figure 6, sans risque de fausse manoeuvre. Ensuite, le pain P s'oriente de lui-même dans la goulotte 1, du fait de sa capacité de se déformer et de la forme de la goulotte.Under these conditions, by moving the pallet 71 mentioned above via the jack 70, it is possible and easy to move the bread P to direct it directly into the opening 11 of the chute, as shown in FIG. figure 6 , without risk of false maneuver. Then, the bread P turns itself in the chute 1, because of its ability to deform and the shape of the chute.

Dans l'hypothèse où les goulottes 1 ne sont pas évasées en partie supérieure, il peut être plus délicat d'opérer leur transfert dans ces goulottes. Dans une autre situation, on peut tout simplement rechercher à introduire les pains P dans les goulottes 1, selon une orientation la plus verticale possible. C'est la situation représentée aux figures 7 et 8 dans lesquelles le réceptacle 6 prend une orientation en biais lorsqu'il est positionné en regard d'une goulotte à approvisionner.In the event that the chutes 1 are not flared at the top, it may be more difficult to operate their transfer in these chutes. In another situation, one can simply seek to introduce the rolls P in the troughs 1, in a direction as vertical as possible. This is the situation represented in Figures 7 and 8 in which the receptacle 6 takes an angled orientation when positioned facing a chute to supply.

Pour ce faire, sont associés au réceptacle 6 des moyens non représentés tels qu'une bielle ou une came, qui permettent à ce réceptacle de se positionner en biais, par relevage de son extrémité opposée à la goulotte 1 à alimenter.To do this, are associated with the receptacle 6 unrepresented means such as a rod or a cam, which allow this receptacle to be positioned at an angle, by lifting its end opposite the chute 1 to feed.

Dans cette position, illustrée aux figures 7 et 8, le "travail" de la palette 71 du vérin 7 est facilitée par le fait que le pain P a tendance, de par son poids, à glisser naturellement le long du réceptacle, et à rentrer dans la goulotte.In this position, illustrated in Figures 7 and 8 , the "work" of the pallet 71 of the cylinder 7 is facilitated by the fact that the bread P tends, by its weight, to slide naturally along the receptacle, and to enter the chute.

Grâce à l'invention, il est possible d'approvisionner toutes les goulottes en un temps record, de sorte que la qualité et la régularité de tranchage des pains n'est aucunement affectée.Thanks to the invention, it is possible to supply all the chutes in record time, so that the quality and regularity of slicing of the loaves is not affected.

Le fonctionnement de la présente installation est par exemple géré automatiquement via un automate.The operation of this installation is for example automatically managed via a PLC.

Bien que cela ne soit pas représenté sur les figures, on pourrait envisager d'avoir affaire à une installation I dont la plate-forme 2 comporte sur chacun de ses deux côtés un ensemble E tel que celui précité, le réceptacle 6 étant configuré pour déplacer les pains P soit en direction d'un ensemble, soit en direction de l'ensemble opposé, en fonction des besoins.Although this is not shown in the figures, one could consider having to deal with an installation I whose platform 2 has on each of its two sides a set E such as that mentioned above, the receptacle 6 being configured to move the breads P is in the direction of a set, or in the direction of the opposite set, according to the needs.

Enfin, comme représenté schématiquement à la figure 9, il est possible, sur un même site, de mettre en place au moins deux installations I telles que celle de la figure 1, pour autant que celle-ci soit positionnée tête-bêche.Finally, as shown schematically in figure 9 , it is possible, on the same site, to set up at least two facilities I such as that of the figure 1 as long as it is positioned head to tail.

Ces deux installations voisines sont alors traversées par un seul et même convoyeur C, par exemple pour la découpe et le dépôt de produits alimentaires différents.These two neighboring installations are then crossed by a single conveyor C, for example for cutting and depositing different food products.
