Description

La présente invention se rapporte à une plaque intercalaire pour des ensembles de piles de plateaux alvéolés recevant des oeufs.The present invention relates to an intermediate plate for sets of stacks of honeycomb trays receiving eggs.

Il est bien connu d'utiliser pour le stockage et/ou le transport d'oeufs, des plateaux minces en carton ou en matière plastique, comportant sur les deux faces des séries d'alvéoles séparés par des crêtes - ou plots - agencés de telle manière que chaque saillie de l'une des faces du plateau corresponde à un alvéole de la face opposée.It is well known to use for the storage and / or transport of eggs, thin cardboard or plastic trays, having on both sides series of cells separated by ridges - or studs - arranged in such a way that each projection from one of the faces of the plate corresponds to a cell on the opposite face.

Il est d'usage que de tels plateaux alvéolés et garnis de produits soient disposés à l'intérieur de cartons d'emballage dans un but de protection lors de leur manutention.It is customary for such honeycomb trays filled with products to be arranged inside of packing boxes for the purpose of protection during their handling.

Il arrive également que ces plateaux alvéolés garnis soient disposés en couches directement sur des palettes de manutention, et séparées par des intercalaires de carton lisse, lesquelles palettes sont ensuite revêtues d'un moyen de protection destiné à retenir l'ensemble du chargement sur la palette. Il s'agit par exemple d'un film plastique ajouré, semblable à un filet.It also happens that these filled honeycomb trays are arranged in layers directly on handling pallets, and separated by dividers smooth cardboard, which pallets are then coated with a protective means intended to hold the entire load on the pallet. It is for example a plastic film openwork, similar to a net.

Dans le cas des oeufs, chaque plateau comporte le plus souvent trente alvéoles. Habituellement, on dispose douze piles de six plateaux sur une palette de façon à en recouvrir toute la surface.In the case of eggs, each tray usually has thirty alveoli. Usually there are twelve stacks of six trays on a pallet so to cover the entire surface.

On recouvre alors cet ensemble de plateaux alvéolés vides et retournés, puis d'une feuille intercalaire lisse. Sur le dessus de la feuille, on dispose un nouvel ensemble de plateaux et ainsi de suite.We then cover this set of empty and turned honeycomb trays, then a smooth interlayer sheet. On the top of the sheet, we have a new set of trays and so on.

Chaque ensemble comprend donc deux mille cent soixante oeufs et de tels ensembles superposés constituent la totalité ou la partie supérieure d'une palette de transport et/ou de stockage d'oeufs.Each set therefore includes two thousand one hundred and sixty eggs and such stacked sets make up all or the top of a palette of transport and / or storage of eggs.

Cette technique d'agencement et de stockage permet de réaliser une économie de carton d'emballage et une manipulation des oeufs plus aisée.This arrangement and storage technique allows a saving of cardboard packaging and easier handling of eggs.

Toutefois, le chargement porté par la palette présente un manque de stabilité pendant sa manutention. En effet, les piles contiguës peuvent glisser les unes par rapport aux autres et déstabiliser "l'édifice", en provoquant la détérioration des produits transportés, par écrasement.However, the load carried by the pallet presents a lack of stability during handling. Indeed, the adjoining stacks can slide one by compared to others and destabilize "the building", causing the deterioration of products transported, by crushing.

Le document US-A-5 205 410 concerne une plaque intercalaire pour des ensembles de piles de plateaux alvéolés recevant des oeufs. Cette plaque, par exemple en polyéthylène rigide, comporte un rebord apte à recouvrir et se caler sur la couche de piles inférieure. Document US-A-5 205 410 relates to an intermediate plate for sets of stacks of honeycomb trays receiving eggs. This plate, for example in rigid polyethylene, has a rim capable of covering and wedging on the layer of batteries lower.

Dans son fond sont formées de petites cuvettes qui ont pour but de s' intercaler entre les plots de plateaux alvéolés vides, disposés au-dessus de la couche de piles inférieure. Une telle plaque assurè la stabilité de l'ensemble au cours de sa manutention.In its bottom are formed small bowls which aim to interpose between the pads of empty honeycomb trays, placed above the layer of lower batteries. Such a plate ensures the stability of the assembly during its handling.

L'emploi de plateaux vides se traduit, pour l'ensemble d'une palette chargée de plateaux d'oeufs, par une augmentation sensible de sa hauteur globale et cela grève également le coût de l'ensemble.The use of empty trays translates, for an entire pallet loaded with egg trays, by a significant increase in its overall height and this also strike the cost of the whole.

Or, il est traditionnel de procéder à l'inspection visuelle des oeufs placés en sommet de palette. Ce sont le plus souvent les oeufs les plus abimés et les moins résistants qui y sont placés. Cette inspection est rendue difficile, voire impossible, conformément à ce document de l'état de la technique, du fait de la hauteur de la palette.However, it is traditional to visually inspect the eggs placed at the top of the palette. These are most often the most damaged and least damaged eggs. resistant placed there. This inspection is made difficult, if not impossible, in accordance with this state of the art document, due to the height of the pallet.

De plus, comme cela est visible plus particulièrement à la figure 3 de ce document, la liaison de la plaque intercalaire avec le plateau le plus bas de l'ensemble supérieur se fait seulement au niveau de ses bords relevés, de sorte que les forces de contact horizontales sont concentrées uniquement au niveau de ces bords rectilignes. Nécessairement, le matériau de la plaque est très rigide pour pouvoir supporter de tels efforts.In addition, as can be seen more particularly in FIG. 3 of this document, the connection of the intermediate plate with the lowest plate of the assembly upper is only done at its raised edges, so that the forces of horizontal contacts are concentrated only at these rectilinear edges. Necessarily, the material of the plate is very rigid to be able to support such efforts.

En ce qui concerne la liaison de la plaque avec les plateaux les plus hauts de l'ensemble inférieur, les cuvettes sont emboítées entre les plots en plastique de plateaux vides. Il s'exerce sur l'ensemble de la plaque des forces de contact sans frottement qui sont concentrées sur un nombre réduit de sommets de plots.Regarding the connection of the plate with the highest plates of the lower assembly, the bowls are fitted between the plastic studs of empty trays. It exerts on the entire plate contact forces without friction which are concentrated on a reduced number of tops of studs.

La présente invention pallie ces inconvénients.The present invention overcomes these drawbacks.

Elle vise, tout en conservant le même nombre d'articles transportés, à réduire la hauteur de l'empilement, à abaisser son centre de gravité, et à réduire le nombre de plateaux alvéolés utilisés.It aims, while keeping the same number of items transported, to reduce the height of the stack, lower its center of gravity, and reduce the number of honeycomb trays used.

Par ailleurs, elle vise à fournir une plaque intercalaire qui présente des zones de contact étendues avec les plateaux alvéolés, afin d'améliorer la stabilité de l'ensemble.Furthermore, it aims to provide an intermediate plate which has extended contact areas with the honeycomb trays, to improve the stability of all.

Ces objectifs ainsi que d'autres sont atteints conformément à l'invention.These and other objectives are achieved in accordance with the invention.

Elle a donc trait à une plaque intercalaire destinée à être étendue entre deux ensembles superposés de piles juxtaposées de plateaux alvéolés, chaque plateau comprenant une pluralité d'alvéoles séparés par des plots et recevant chacun un article fragile, du type comportant des organes de retenue aptes à assurer d'une part la cohésion des piles d'un même ensemble et, d'autre part, la liaison des deux ensembles superposés.It therefore relates to an intermediate plate intended to be extended between two stacked sets of juxtaposed stacks of honeycomb trays, each tray comprising a plurality of cells separated by studs and each receiving an article fragile, of the type comprising retaining members capable of ensuring cohesion on the one hand stacks of the same assembly and, on the other hand, the connection of the two superimposed assemblies.

Selon l'invention, lesdits organes de retenue consistent en des alvéoles et plots similaires à ceux. des plateaux alvéolés, de sorte qu'elle est adaptée pour s'appuyer par le fond de ses alvéoles sur les plots des plateaux de l'ensemble inférieur, et pour recevoir les plateaux de l'ensemble supérieur par emboítement mutuel des alvéoles et des plots.According to the invention, said retaining members consist of cells and studs similar to those. honeycomb trays, so that it is adapted to rest by the bottom of its cells on the studs of the trays of the lower assembly, and for receive the trays of the upper assembly by mutual interlocking of the cells and studs.

Ainsi, la plaque intercalaire s'imbrique parfaitement entre deux piles superposées et est directement en contact avec les oeufs de la pile inférieure. Comparativement à la technique décrite dans le document américain précité, on économise, selon l'invention, l'emploi de plateaux alvéolés vides.Thus, the interlay plate fits perfectly between two batteries superimposed and is directly in contact with the eggs of the lower stack. Comparatively to the technique described in the aforementioned American document, one saves, according to the invention, the use of empty honeycomb trays.

De plus, pour un nombre identique d'oeufs par palette, la hauteur de l'édifice est moindre, conformément à l'invention.In addition, for an identical number of eggs per pallet, the height of the building is less, in accordance with the invention.

Ceci permet de réaliser plus facilement le contrôle visuel des oeufs visibles en somme de palette. La palette occupe un encombrement moindre, ce qui n'est pas négligeable lors d'un transport en camion. Le centre de gravité de l'édifice étant abaissé, sa stabilité est améliorée.This makes it easier to visually inspect visible eggs basically a palette. The pallet takes up less space, which is not negligible during truck transport. The center of gravity of the building being lowered, its stability is improved.

Enfin, conformément à l'invention, aucun obstacle n'empêche une dépalettisation automatique d'un édifice puisque la plaque intercalaire ne comporte pas de débord et n'occupe pas plus de place en hauteur qu'un plateau alvéolé classique.Finally, in accordance with the invention, no obstacle prevents a automatic depalletization of a building since the intermediate plate does not have any overflows and occupies no more space in height than a conventional honeycomb tray.

Par ailleurs, selon d'autres caractéristiques avantageuses mais non limitatives :

  • la plaque est apte à recouvrir au moins une partie de la surface desdits ensembles;
  • la plaque est divisée en un nombre de surfaces élémentaires qui correspond au nombre de piles de chaque ensemble, ces surfaces étant séparées deux à deux par une zone intermédiaire dont la largeur est égale à la valeur de l'écartement entre deux piles voisines ;
  • certaines desdites zones intermédiaires sont partiellement évidées;
  • la plaque est réalisée en carton ou en matière plastique.
Furthermore, according to other advantageous but non-limiting characteristics:
  • the plate is able to cover at least part of the surface of said assemblies;
  • the plate is divided into a number of elementary surfaces which corresponds to the number of piles of each set, these surfaces being separated two by two by an intermediate zone whose width is equal to the value of the spacing between two neighboring piles;
  • some of said intermediate zones are partially hollowed out;
  • the plate is made of cardboard or plastic.

A la figure 1 est représenté de manière très schématique, un chargement 1 de plateaux alvéolés recevant des oeufs, en place sur une palette 2.In Figure 1 is shown very schematically, a load 1 honeycomb trays receiving eggs, placed on a pallet 2.

Il s'agit d'une palette du commerce, par exemple en bois, de dimensions standard et de type utilisé dans bon nombre d'industries.It is a commercial pallet, for example wooden, of dimensions standard and type used in many industries.

De manière bien connue, comme cela a été évoqué au début de la présente description, des piles de plateaux alvéolés 5 contenant des oeufs (non représentés) sont réparties sur la surface de la palette.In a well known manner, as was mentioned at the beginning of this description, stacks of blister trays 5 containing eggs (not shown) are spread over the surface of the pallet.

Avec des plateaux alvéolés de dimensions standard, aptes à recevoir trente oeufs répartis en cinq lignes de six oeufs, douze piles juxtaposées peuvent être déposées sur la palette pour former un ensemble 3. Chaque pile comporte de préférence six plateaux alvéolés 5.With standard size honeycomb trays, able to accommodate thirty eggs divided into five lines of six eggs, twelve juxtaposed piles can be placed on the pallet to form a set 3. Each stack preferably has six honeycomb trays 5.

On a désigné par les références 4a, 4b et 4c trois piles de plateaux 5.Three stacks of trays 5 have been designated by the references 4a, 4b and 4c.

Au-dessus de l'ensemble 3 est disposé un second ensemble du même type 3', lequel reçoit également un ensemble 3''. La palette supporte habituellement cinq ensembles de ce type.Above set 3 is a second set of the same type 3 ', which also receives a 3' 'set. The pallet usually supports five sets of this type.

Dans l'exemple de la figure 1, une plaque intercalaire 6 est étendue entre deux ensembles superposés, c'est-à-dire entre les ensembles 3 et 3', et entre les ensembles 3' et 3".In the example of FIG. 1, an intermediate plate 6 is extended between two superimposed sets, i.e. between sets 3 and 3 ', and between 3 'and 3 "sets.

Il s'agit par exemple d'une plaque cartonnée ou en matière plastique, qui recouvre la totalité de la surface de chaque ensemble.This is for example a cardboard or plastic plate, which covers the entire surface of each set.

De manière connue, cette plaque comporte des moyens de retenue, non représentés, aptes à assurer d'une part la cohésion des piles 4a, 4b, 4c d'un même ensemble 3,3' ou 3'' et, d'autre part, la liaison entre deux ensembles superposés.In known manner, this plate includes retaining means, not shown, capable of ensuring on the one hand the cohesion of the stacks 4a, 4b, 4c of the same 3.3 'or 3' 'assembly and, on the other hand, the connection between two superimposed assemblies.

Comme le montre la figure 2 annexée, on notera que la plaque conforme à l'invention est divisée en une série de surfaces élémentaires 7a, 7b, 7c, etc. qui correspondent au nombre et à l'emplacement des piles de plateaux alvéolés.As shown in Figure 2 attached, it will be noted that the plate conforming to the invention is divided into a series of elementary surfaces 7a, 7b, 7c, etc. corresponding the number and location of the stacks of honeycomb trays.

Ces surfaces sont séparées deux à deux par une zone intermédiaire 8 dont la largeur est égale à celle qui sépare deux piles voisines de plateaux alvéolés. Cette largeur a volontairement été exagérée à la figure 2 pour bien mettre en évidence l'emplacement et la disposition relative de ces zones intermédiaires.These surfaces are separated two by two by an intermediate zone 8 of which the width is equal to that which separates two neighboring stacks of honeycomb trays. This width has been deliberately exaggerated in Figure 2 to highlight the location and the relative arrangement of these intermediate zones.

A la figure 3 est représentée en détail, en vue de dessus et partiellement, une plaque intercalaire conforme à l'invention.In FIG. 3 is shown in detail, seen from above and partially, an intermediate plate according to the invention.

Selon l invention, les organes de retenue 60 de la plaque consistent en des alvéoles 61 et des plots 62 similaires à ceux des plateaux alvéolés classiques destinés à recevoir des oeufs.According to the invention, the plate retaining members 60 consist of cells 61 and studs 62 similar to those of conventional honeycomb trays intended for receive eggs.

Il s'agit par exemple d'une plaque en matière plastique ou en carton, moulée selon une technique similaire à celle utilisée pour le moulage des plateaux alvéolés, ce qui en réduit le prix de revient.This is for example a plastic or cardboard plate, molded using a technique similar to that used for molding the trays honeycombed, which reduces the cost price.

La plaque comprend douze surfaces élémentaires 7. Seule l'une de celles-ci 7d est représentée entièrement sur la figure.The plate includes twelve elementary surfaces 7. Only one of these 7d is shown entirely in the figure.

Elle comporte une série de cinq lignes de cinq alvéoles 61, séparés diagonalement deux à deux par un plot 62.It comprises a series of five lines of five cells 61, separated diagonally two by two by a pad 62.

La surface 7d est séparée de la surface 7c par une zone intermédiaire 8 partiellement évidée. Elles ne sont reliées l'une à l'autre que par deux éléments de liaison 64 et 65. L'écartement entre les surfaces 7c et 7d correspond à celui qui sépare deux piles voisines de plateaux alvéolés. Il en va de même pour toutes les autres surfaces élémentaires.The surface 7d is separated from the surface 7c by an intermediate zone 8 partially hollowed out. They are connected to each other only by two connecting elements 64 and 65. The spacing between surfaces 7c and 7d corresponds to that which separates two stacks adjacent to honeycomb trays. The same goes for all other elementary surfaces.

Conformément à l'invention et comme le montre la figure 6, la plaque est adaptée pour s'appuyer par le fond de ses alvéoles 61 sur les plots 51 des plateaux 5 de l'ensemble inférieur. Le contour d'un plateau d'un tel ensemble a été délimité en traits pointillés à la figure 3 et les oeufs E qu'il reçoit, représentés sous la forme de cercles, également en traits pointillés.According to the invention and as shown in Figure 6, the plate is adapted to rest by the bottom of its cells 61 on the pads 51 of the plates 5 of the lower assembly. The outline of a tray of such an assembly has been delimited in dotted lines in FIG. 3 and the eggs E which it receives, represented in the form of circles, also in dotted lines.

Les frottements des alvéoles 61 sur les plots 51 des plateaux de l'ensemble inférieur sont suffisants pour assurer la cohésion des piles d'un même ensemble dans une direction horizontale.The friction of the cells 61 on the pads 51 of the plates of the assembly lower are sufficient to ensure the cohesion of the batteries of the same set in a horizontal direction.

Ainsi, les forces de contact avec frottement s'exercent sur 360 plots 51, soit environ sur 720 cm2.Thus, the contact forces with friction are exerted on 360 pads 51, or approximately on 720 cm 2 .

La plaque 6 est par ailleurs adaptée pour recevoir les plateaux de l'ensemble supérieur par emboítement mutuel des alvéoles et des plots. C'est ce qui a été représenté à la figure 6 (flèches f). Pour ce faire, les plateaux de cet ensemble sont déposés après avoir subi une rotation d'un quart de tour par rapport aux plateaux de l'ensemble inférieur.The plate 6 is also adapted to receive the plates of the upper assembly by mutual interlocking of the cells and the studs. This is what has been shown in Figure 6 (arrows f ). To do this, the plates of this assembly are deposited after having undergone a rotation of a quarter turn relative to the plates of the lower assembly.

Cet emboítement assure la liaison entre les ensembles superposés.This socket ensures the connection between the superimposed assemblies.

Les forces de contact sont réparties sur 360 demi-alvéoles de 10 cm2, soit une surface de contact de 3600 cm2. The contact forces are distributed over 360 half-cells of 10 cm 2 , i.e. a contact surface of 3600 cm 2 .

Du fait de la répartition des forces et de la large surface de contact, on peut utiliser pour les plaques intercalaires un matériau peu résistant, tel que du carton ou du polystyrène en feuille mince. L'emploi de ce matériau ne serait pas possible, conformément au brevet américain précité, du fait de la faible surface de contact.Due to the distribution of forces and the large contact surface, use a weak material for the intermediate plates, such as cardboard or thin sheet polystyrene. The use of this material would not be possible, in accordance to the aforementioned US patent, due to the small contact surface.

On notera que lorsqu'une palette est complètement chargée, elle peut être entourée d'un film plastique éventuellement ajouré, ou d'un feuillard.Note that when a pallet is fully loaded, it can be surrounded by a possibly perforated plastic film, or a strip.

Comme déjà dit plus haut, outre l'avantage d'accroítre la stabilité des palettes chargées, la plaque selon l'invention permet de réduire la hauteur des chargements de quelques décimètres, ce qui en facilite la réalisation et le déplacement, par abaissement du centre de gravité. De plus, cela permet de réaliser plus facilement le contrôle visuel des oeufs des piles supérieures, ainsi que la manutention de l'édifice.As already said above, in addition to the advantage of increasing the stability of loaded pallets, the plate according to the invention makes it possible to reduce the height of the loadings a few decimeters, which makes it easier to carry and move, for example lowering of the center of gravity. In addition, this makes it easier to carry out the visual inspection of the eggs in the upper piles, as well as the handling of the building.

Dans une forme de réalisation non représentée sur les figures, la plaque conforme à l'invention occupe seulement une partie de la surface des ensembles de piles. A titre d'exemple, elle recouvre la totalité des piles centrales de chaque ensemble et seulement une petite partie des piles périphériques. Bien que de surface réduite, cette plaque est apte à assurer la cohésion des piles d'un même ensemble et la liaison de deux ensembles superposés.In an embodiment not shown in the figures, the plate according to the invention occupies only part of the surface of the battery assemblies. For example, it covers all of the central stacks in each set and only a small part of the peripheral batteries. Although small in area, this plate is capable of ensuring the cohesion of the batteries of the same assembly and the connection of two superimposed sets.

Selon un autre mode de réalisation, cette plaque affecte la forme d'une croix ou d'un cadre recouvrant seulement les piles périphériques.According to another embodiment, this plate takes the form of a cross or a frame covering only the peripheral batteries.

Bien entendu, les ensembles séparés par la plaque conforme à l'invention, ne sont pas nécessairement en appui sur une palette. Ils peuvent reposer directement sur le sol.Of course, the assemblies separated by the plate according to the invention, are not necessarily supported on a pallet. They can rest directly on floor.

On a représenté à la figure 7, un édifice 1 de plateaux alvéolés en cours de déchargement. Un appareil automatique 9 - ou télémanipulateur - est employé à cet effet. Il comporte une embase 90 apte à être déplacée selon la double flèche g1 et pilotée à distance. Il est également équipé d'une série de bras articulés et éventuellement télescopiques 91 et 92, à l'extrémité de laquelle est montée une fourche 93 à deux bras parallèles 94.FIG. 7 shows a building 1 of honeycomb trays during unloading. An automatic device 9 - or remote manipulator - is used for this purpose. It has a base 90 capable of being moved according to the double arrow g 1 and controlled remotely. It is also equipped with a series of articulated and possibly telescopic arms 91 and 92, at the end of which is mounted a fork 93 with two parallel arms 94.

Comme le montre la figure 8, du fait que la plaque intercalaire 6 ne présente aucun débord et qu'elle a une hauteur sensiblement égale à celle d'un plateau alvéolé 5, il existe un passage F entre deux plateaux voisins 5, de dimensions suffisantes pour pouvoir y glisser un bras 94 du télémanipulateur. Celui-ci présente de préférence, comme cela est visible, une section coudée, de façon à glisser et à se positionner plus facilement le long d'un plateau 5.As shown in FIG. 8, owing to the fact that the intermediate plate 6 has no projection and that it has a height substantially equal to that of a honeycomb plate 5, there is a passage F between two neighboring plates 5, of sufficient dimensions to be able to slide an arm 94 of the manipulator there. The latter preferably has, as is visible, a bent section, so as to slide and position more easily along a plate 5.

L'écartement mutuel entre les bras 94 est choisi pour que ces derniers puissent se placer de chaque côté des bords opposés obliques d'un plateau alvéolé, en enserrant légèrement celui-ci. The mutual spacing between the arms 94 is chosen so that the latter can be placed on each side of the oblique opposite edges of a honeycomb tray, in lightly enclosing it.

La longueur des bras 94 peut être prévue, comme cela est montré sur te figure 7, pour pouvoir déplacer ensemble plusieurs piles 3 disposées les unes derrière les autres.The length of the arms 94 can be provided, as shown on te Figure 7, to be able to move together several batteries 3 arranged one behind the other.

Le télémanipulateur est représenté en train de décharger des piles en partie inférieure de l'ensemble 1. Il est bien évident que l'on commence par décharger les piles tes plus hautes.The remote manipulator is shown partially discharging batteries bottom of the set 1. It is obvious that we start by discharging the batteries your highest.

On a également représenté à la figure 7, un convoyeur C à tapis mobile sur lequel une pile 3 de plateaux a préalablement été déposée. Le sens de déplacement du brin supérieur est symbolisé par la flèche g2.FIG. 7 also shows a conveyor belt C with a movable belt on which a stack 3 of trays has been previously deposited. The direction of movement of the upper strand is symbolized by the arrow g 2 .
