Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention se rapporte à un plateau de conditionnement. Le plateau de conditionnement trouve une application particulière et non exclusive dans l'industrie du conditionnement de bouteille, par exemple des bouteilles de champagne.The invention relates to a conditioning tray. The packaging tray finds a particular and non-exclusive application in the bottle packaging industry, for example bottles of champagne.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Pour le conditionnement de bouteilles, il est courant de conditionner les bouteilles horizontalement et aussi sur plusieurs niveaux verticalement. La Figure 1 représente une coupe partielle illustrant schématiquement le conditionnement 1 de bouteilles 2. Les bouteilles 2 sont disposées sur des plateaux intercalaires 10A, 10B qui ont pour fonctions, d'une part, de positionner précisément les bouteilles sous forme de rangées et de colonnes dans le plan horizontal, et, d'autre part, de séparer les niveaux successif selon l'axe vertical z. Généralement, un tel ensemble est supporté par une palette 3 qui facilite la manutention et le transport.For the packaging of bottles, it is common to condition the bottles horizontally and also on several levels vertically. The Figure 1 represents a partial section schematically illustrating the packaging 1 of bottles 2. The bottles 2 are arranged on intermediate plates 10A, 10B whose functions are, on the one hand, to precisely position the bottles in the form of rows and columns in the plane horizontal, and, secondly, to separate the successive levels along the vertical axis z. Generally, such an assembly is supported by a pallet 3 which facilitates handling and transport.

Généralement, le conditionnement des bouteilles est automatisé. La Figure 2 représente une coupe partielle illustrant schématiquement le dépilage de plateaux intercalaires. Un empilement 8 de plateaux intercalaires 10A, 10B est livré sur une palette. Un robot 9 est utilisé pour dépiler les plateaux intercalaires 10A, 10B qui seront utilisés pour conditionner les bouteilles. Un tel robot 9 comporte un manipulateur à ventouse qui saisit par aspiration un à un les plateaux intercalaires 10A, 10B.Generally, the packaging of the bottles is automated. The Figure 2 represents a partial section schematically illustrating the unstacking of intermediate plates. A stack 8 of interposer trays 10A, 10B is delivered on a pallet. A robot 9 is used to depilate the intermediate plates 10A, 10B which will be used to condition the bottles. Such a robot 9 comprises a suction manipulator which captures by suction one by one the intermediate plates 10A, 10B.

Typiquement, les plateaux intercalaires sont fabriqués en matériau plastique, par exemple du polystyrène PS (de densité de l'ordre de 1,05 g/cm3 et d'épaisseur de l'ordre de 500µm), par thermoformage.Typically, the intermediate trays are made of plastic material, for example PS polystyrene (density of the order of 1.05 g / cm3 and thickness of the order of 500 .mu.m), by thermoforming.

La Figure 3 représente une coupe partielle illustrant schématiquement un empilement 8 de quatre plateaux intercalaires 10A, 10B selon l'art antérieur. Le plateau intercalaire 10A, 10B comporte une face inférieure et une face supérieure et une pluralité de cônes tronqués 4A, 4B. On entend par cône tronqué, un cône ayant un sommet à surface sensiblement plane 5, ladite surface étant parallèle au plan du plateau intercalaire 10A, 10B. Chaque cône tronqué 4A, 4B fait saillie de la face supérieure de manière à ménager une cavité du côté de la face inférieure. Le sommet du cône faisant saillie est arrangé pour s'enficher dans un fond convexe d'une bouteille 2 positionnée sur le plateau intercalaire 10A, 10B (voir Figure 1). La cavité est arrangée pour recevoir le col d'une bouteille 2 positionnée sous le plateau intercalaire 10A, 10B (voir Figure 1). Afin de faciliter le dépilage, il existe deux types de plateau intercalaire 10A, 10B se différenciant par la forme du sommet du cône 4A, 4B. Dans l'empilement 8, les plateaux intercalaires 10A, 10B sont posés les uns sur les autres dans le sens de la hauteur z. Un plateau intercalaire du premier type 10A alterne avec un plateau intercalaire du second type 10B. Les cônes tronqués 4A du plateau intercalaire du premier type 10A s'enfiche dans les cônes tronqués 4B du plateau intercalaire du second type 10B. De cette manière l'empilement 8 est assez compact. Afin de faciliter le dépilage successif des plateaux intercalaires par le robot 9, chaque cône est muni d'un plot de dépilage 6, 7 au niveau de la surface sensiblement plane 5 du sommet du cône. Plus précisément, les cônes tronqués 4A du plateau intercalaire du premier type 10A comportent un plot de dépilage 6 ayant un décrochement au dessus de la surface sensiblement plane 5 suivi d'un décrochement central concentrique vers le centre et en dessous de la surface sensiblement plane 5. Les cônes tronqués 4B du plateau intercalaire du second type 10B comportent un plot de dépilage 7 ayant un léger décrochement au dessus de la surface sensiblement plane 5. La hauteur du décrochement central du plot de dépilage 6 définit le pas d'empilage δ pour l'empilement 8 de plateaux intercalaires.The Figure 3 represents a partial section diagrammatically illustrating a stack 8 of four interlayers 10A, 10B according to the prior art. The intermediate plate 10A, 10B has a lower face and an upper face and a plurality of truncated cones 4A, 4B. Truncated cone means a cone having a substantially planar surface top 5, said surface being parallel to the plane of the intermediate plate 10A, 10B. Each truncated cone 4A, 4B protrudes from the upper face so as to provide a cavity on the side of the lower face. The top of the protruding cone is arranged to be plugged into a convex bottom of a bottle 2 positioned on the intermediate plate 10A, 10B (see FIG. Figure 1 ). The cavity is arranged to receive the neck of a bottle 2 positioned under the intermediate plate 10A, 10B (see Figure 1 ). To facilitate unstacking, there are two types intermediate plate 10A, 10B differing in the shape of the top of the cone 4A, 4B. In the stack 8, the intermediate plates 10A, 10B are placed one above the other in the direction of the height z. An intermediate plate of the first type 10A alternates with an intermediate plate of the second type 10B. The truncated cones 4A of the intermediate plate of the first type 10A is plugged into the truncated cones 4B of the intermediate plate of the second type 10B. In this way the stack 8 is quite compact. In order to facilitate the successive unstacking of the intermediate plates by the robot 9, each cone is provided with an unstacking stud 6, 7 at the level of the substantially flat surface 5 of the apex of the cone. More specifically, the truncated cones 4A of the intermediate plate of the first type 10A comprise an unstacking stud 6 having a recess above the substantially planar surface 5 followed by a central recess concentric towards the center and below the substantially planar surface 5 The truncated cones 4B of the intermediate plate of the second type 10B comprise an unstacking pad 7 having a slight recess above the substantially flat surface 5. The height of the central recess of the unstacking pad 6 defines the stacking pitch δ for the stack 8 of interposed trays.

Dans la pratique, un empilement 8 peut comporter de l'ordre de 500 plateaux intercalaires. Le robot 9 impose une planéité de l'empilement 8 en ce qui concerne le dernier plateau intercalaire 10A ou 10B se trouvant en haut de l'empilement 8 qui va être saisi par aspiration. Typiquement, la variation maximum de hauteur (défaut de planéité) entre un côté et l'autre côté de l'empilement 8 ne doit pas être supérieure à 4 cm, ce qui équivaut à un défaut maximum de planéité de l'ordre de 0,08 mm par plateau intercalaire 10A ou 10 B. Au-delà de cette valeur, le manipulateur à ventouse comportant un cadre de préhension muni de ventouses à soufflets n'est plus capable de saisir sans défaut les plateaux de haut en bas de l'empilement. Une telle planéité est difficilement atteignable avec les plateaux intercalaires tels que décrit. En effet, les plateaux intercalaires sont fabriqués en polystyrène recyclée dont les caractéristiques mécaniques et les paramètres de formages sont fluctuants ce qui influencent la répartition de matière et induisent des variations de rigidité.In practice, a stack 8 may comprise of the order of 500 interposed trays. The robot 9 imposes a flatness of the stack 8 with respect to the last intermediate plate 10A or 10B at the top of the stack 8 which will be grasped by suction. Typically, the maximum height variation (flatness defect) between one side and the other side of the stack 8 must not be greater than 4 cm, which is equivalent to a maximum flatness defect of the order of 0, 08 mm per intermediate plate 10A or 10 B. Above this value, the suction pad with a gripper frame with bellows suction cups is no longer able to grip the trays from top to bottom of the stack without defect. . Such flatness is difficult to achieve with the interposed trays as described. In fact, the interlayers are made of recycled polystyrene whose mechanical characteristics and forming parameters are fluctuating, which influence the distribution of material and induce variations in rigidity.

  • création d'un plot de dépilage dans un plateau intercalaire d'un premier type comportant un motif ayant une structure symétrique faisant saillie de ladite surface dont une hauteur définit un pas d'empilage,
  • création d'un plot de dépilage dans un plateau intercalaire d'un second type par une rotation de la structure symétrique dudit motif dans un plan de ladite surface, et
  • empilage de plusieurs plateaux intercalaires du premier et du second type selon une direction verticale de manière alternée.
According to yet another aspect, the invention proposes a method of manufacturing an intermediate tray for the horizontal and vertical packaging of bottles, the intermediate plate having a lower face and an upper face and a plurality of truncated cones organized in rows and columns, each cone projecting from the upper face so as to provide a cavity on the side of the lower face, each cone being provided with an unstacking pad at a substantially flat surface of an apex of the cone, the top of the cone making protrusion being arranged to plug into a convex bottom of a bottle, the cavity being arranged to receive the neck of another bottle, the method of manufacture comprises the steps of:
  • creating an unstacking pad in a spacer plate of a first type comprising a pattern having a symmetrical structure projecting from said surface, a height of which defines a stacking pitch,
  • creating an unstacking pad in a spacer plate of a second type by rotating the symmetrical structure of said pattern in a plane of said surface, and
  • stacking a plurality of intermediate trays of the first and second type in a vertical direction alternately.

Une partie du moule de formage destinée à former lesdits plots de dépilage peut-être tournée d'un angle de rotation déterminé entre deux formages successifs.A part of the forming mold intended to form said unstacking studs can be rotated by a determined rotation angle between two successive forming operations.

Le plateau intercalaire et sa méthode de fabrication selon l'invention permettent d'assurer une planéité globale de l'empilement inférieure à la tolérance de positionnement verticale imposée par le fonctionnement du robot (variation de hauteur au niveau du dernier plateau intercalaire de l'empilement inférieure à 4 cm). Par conséquent, le défaut maximum de planéité inférieur à 0,08 mm par plateau intercalaire est possible avec l'invention.The intermediate plate and its manufacturing method according to the invention make it possible to ensure overall flatness of the stack less than the vertical positioning tolerance imposed by the operation of the robot (variation of height at the level of the last intermediate plate of the stack less than 4 cm). Therefore, the maximum flatness defect of less than 0.08 mm per interposer tray is possible with the invention.

Cette tolérance est atteinte quelque soit les variations de rigidité du plastique employé pour les fabriquer. Par conséquent, le robot assurant le dépilage peut fonctionner de manière optimum. Avec l'invention, cette planéité est même obtenue en empilant jusqu'à 1000 plateaux intercalaires ce qui est bien supérieur à l'art antérieur car ceci impose un défaut maximum de planéité inférieur à 0,04 mm par plateau intercalaire.This tolerance is reached regardless of the variations in rigidity of the plastic used to make them. Therefore, the unstacking robot can function optimally. With the invention, this flatness is even obtained by stacking up to 1000 interposed plates which is much superior to the art previous because this imposes a maximum flatness defect of less than 0.04 mm per intermediate plate.

L'invention permet aussi une fabrication en continue des plateaux intercalaires de premier et second type avec un seul moule dont seule une partie est tournée. D'autres avantages ressortiront de la description détaillée de l'invention qui va suivre.The invention also allows a continuous manufacture of intermediate trays of first and second type with a single mold of which only a portion is rotated. Other advantages will emerge from the detailed description of the invention which follows.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La Figure 4 représente une vue de dessus illustrant schématiquement un plateau intercalaire d'un premier type 10A selon un premier mode de réalisation de l'invention. La Figure 5 représente une vue de côté illustrant schématiquement un empilement de quatre plateaux intercalaires selon le premier mode de réalisation de l'invention. Un plateau intercalaire d'un second type 10B n'est pas représenté en vue de dessus mais est analogue au plateau intercalaire du premier type 10A sauf en ce qui concerne le plot de dépilage.The Figure 4 is a top view schematically illustrating a spacer plate of a first type 10A according to a first embodiment of the invention. The Figure 5 is a side view schematically illustrating a stack of four interposer trays according to the first embodiment of the invention. An intermediate plate of a second type 10B is not shown in plan view but is similar to the intermediate plate of the first type 10A except for the unstacking pad.

Le plateau intercalaire 10A respectivement 10B est utilisé pour le conditionnement horizontal et vertical des bouteilles. Le plateau intercalaire 10A respectivement 10B comporte une face inférieure et une face supérieure et une pluralité de cônes tronqués 40A respectivement 40B organisés en rangées et colonnes. Chaque cône 40A respectivement 40B fait saillie de la face supérieure de manière à ménager une cavité du côté de la face inférieure. Le sommet du cône 40A respectivement 40B est une surface sensiblement plane parallèle au plan du plateau intercalaire 10A respectivement 10B. Le sommet du cône 40A respectivement 40B faisant saillie est arrangé pour s'enficher dans un fond convexe d'une bouteille située au dessus du plateau intercalaire 10A respectivement 10B. La cavité est arrangée pour recevoir le col d'une autre bouteille située en dessous du plateau intercalaire 10A respectivement 10B.The intermediate plate 10A and 10B respectively is used for the horizontal and vertical packaging of the bottles. The intermediate plate 10A respectively 10B has a lower face and an upper face and a plurality of truncated cones 40A respectively 40B organized in rows and columns. Each cone 40A or 40B protrudes from the upper face so as to provide a cavity on the side of the lower face. The top of the cone 40A respectively 40B is a substantially flat surface parallel to the plane of the intermediate plate 10A respectively 10B. The top of the cone 40A respectively 40B protruding is arranged to plug into a convex bottom of a bottle located above the intermediate plate 10A respectively 10B. The cavity is arranged to receive the neck of another bottle located below the intermediate plate 10A respectively 10B.

Chaque cône 40A respectivement 40B est muni d'un plot de dépilage 60 respectivement 70 au niveau de cette surface au sommet du cône 40A respectivement 40B. Le plot de dépilage 60 respectivement 70 comporte un motif ayant une structure symétrique faisant saillie de ladite surface dont une hauteur définit un pas d'empilage δ. Les Figures 6 et 7 représentent des vues de dessus et illustrent schématiquement ce motif à structure symétrique pour un plateau intercalaire d'un premier type 10A, respectivement d'un second type 10B selon le premier mode de réalisation de l'invention. Il s'agit de deux segments droits se croisant à angle droit sensiblement en leurs centres. La hauteur des segments (selon l'axe vertical z) définit le pas d'empilage δ. Le pas d'empilage est par exemple de l'ordre de 1,5 à 3 mm. Le motif du plot de dépilage 60 du plateau du premier type 10A se différencie du motif du plot de dépilage 70 du plateau du second type 10B par une rotation de la structure symétrique dans un plan de la surface du sommet du cône. Dans l'exemple, le motif est tourné d'un angle de 45°.Each cone 40A respectively 40B is provided with an unstacking pad 60 respectively 70 at this surface at the top of the cone 40A respectively 40B. The unstacking pad 60 and 70 respectively comprises a pattern having a symmetrical structure projecting from said surface, a height of which defines a stacking pitch δ. The Figures 6 and 7 represent top views and schematically illustrate this symmetrical structure pattern for an intermediate plate of a first type 10A, respectively a second type 10B according to the first embodiment of the invention. These are two straight segments intersecting at right angles substantially in their centers. The height of the segments (along the vertical axis z) defines the stacking step δ. The stacking pitch is for example of the order of 1.5 to 3 mm. The pattern of unstacking pad 60 of the tray of the first type 10A is different from the pattern of unstacking pad 70 of the tray of the second type 10B by a rotation of the symmetrical structure in a plane of the surface of the apex of the cone. In the example, the pattern is rotated at an angle of 45 °.

La rotation de la structure symétrique dans le plan de la surface du sommet 5 crée une zone de report de charge lorsque plusieurs plateaux intercalaires du premier et du second type sont empilés selon une direction verticale de manière alternée. Ceci permet d'atteindre la planéité désirée de l'empilement 8 dans les tolérances de fonctionnement du robot de dépilage.Rotation of the symmetrical structure in the plane of the top surface 5 creates a load transfer area when a plurality of intermediate plates of the first and second type are stacked in a vertical direction alternately. This makes it possible to achieve the desired flatness of the stack 8 in the operating tolerances of the unstacking robot.

La Figure 8 représente une coupe partielle et illustre schématiquement un tel empilement 8 de quatre plateaux intercalaires selon le premier mode de réalisation de l'invention. Les plateaux intercalaires du premier type 10A et ceux du second type 10B sont empilés en alternance, 10A, 10B, 10A, 10B, 10A, etc.... Bien évidemment dans une application de conditionnement industrielle, l'empilement 8 comporte plusieurs centaines de plateaux intercalaires, par exemple entre 500 et 900.The Figure 8 represents a partial section and illustrates schematically such a stack 8 of four intermediate plates according to the first embodiment of the invention. The intermediate plates of the first type 10A and those of the second type 10B are stacked alternately, 10A, 10B, 10A, 10B, 10A, etc .... Of course in an industrial packaging application, the stack 8 comprises several hundred of interlayers, for example between 500 and 900.

La Figure 9 représente une vue de dessus illustrant schématiquement un plateau intercalaire d'un premier type 10A selon un deuxième mode de réalisation de l'invention. Chaque cône 41 A respectivement 41B est muni d'un plot de dépilage 61 respectivement 71 au niveau de la surface 5 au sommet du cône 41 A respectivement 41B.The Figure 9 is a top view schematically illustrating a spacer plate of a first type 10A according to a second embodiment of the invention. Each cone 41A respectively 41B is provided with an unstacking pad 61 respectively 71 at the surface 5 at the top of the cone 41 A respectively 41B.

Les Figures 10 et 11 représentent des vues de dessus illustrant schématiquement un motif à structure symétrique pour un plateau intercalaire d'un premier type 10A, respectivement d'un second type 10B selon le deuxième mode de réalisation de l'invention. Il s'agit d'un demi-cercle concentrique avec le sommet du cône 41 A, 41B.The Figures 10 and 11 are top views schematically illustrating a pattern of symmetrical structure for a spacer plate of a first type 10A, respectively a second type 10B according to the second embodiment of the invention. It is a concentric semicircle with the top of the cone 41A, 41B.

La hauteur du demi-cercle (selon l'axe vertical z) définit le pas d'empilage δ. Le motif du plot de dépilage 61 du plateau du premier type 10A se différencie du motif du plot de dépilage 71 du plateau du second type 10B par une rotation de la structure symétrique dans un plan de la surface du sommet du cône. Dans l'exemple, le motif est tourné d'un angle de 180°.The height of the semicircle (along the vertical axis z) defines the stacking step δ. The pattern of unstacking pad 61 of the plate of the first type 10A differs from the pattern of unstacking pad 71 of the plate of the second type 10B by a rotation of the symmetrical structure in a plane of the surface of the apex of the cone. In the example, the pattern is rotated by an angle of 180 °.

La Figure 12 représente une coupe partielle laquelle illustre schématiquement un empilement de quatre plateaux intercalaires 10A, 10B, 10A, 10B selon ce deuxième mode de réalisation de l'invention.The Figure 12 represents a partial section which schematically illustrates a stack of four intermediate plates 10A, 10B, 10A, 10B according to this second embodiment of the invention.

La Figure 13 représente une vue de dessus illustrant schématiquement un plateau intercalaire d'un premier type 10A selon un troisième mode de réalisation de l'invention. Chaque cône 42A respectivement 42B est muni d'un plot de dépilage 62 respectivement 72 au niveau de la surface 5 au sommet du cône 42A respectivement 42B.The Figure 13 represents a top view schematically illustrating a spacer plate of a first type 10A according to a third embodiment of the invention. Each cone 42A respectively 42B is provided with an unstacking pad 62 respectively 72 at the surface 5 at the top of the cone 42A respectively 42B.

Les Figures 14 et 15 représentent des vues de dessus illustrant schématiquement un motif à structure symétrique pour un plateau intercalaire d'un premier type 10A, respectivement d'un second type 10B selon le troisième mode de réalisation de l'invention. Il s'agit de deux quarts de cercle positionnés tête-bêche ou d'une forme en papillon. La hauteur du papillon (selon l'axe vertical z) définit le pas d'empilage δ.The Figures 14 and 15 are top views schematically illustrating a pattern of symmetrical structure for a spacer plate of a first type 10A, respectively a second type 10B according to the third embodiment of the invention. It is about two quarter-circles positioned head to tail or a butterfly shape. The height of the butterfly (along the vertical axis z) defines the stacking step δ.

Le motif du plot de dépilage 62 du plateau du premier type 10A se différencie du motif du plot de dépilage 72 du plateau du second type 10B par une rotation de la structure symétrique dans un plan de la surface du sommet du cône. Dans l'exemple, le motif est tourné d'un angle de 90°.The pattern of the unstacking pad 62 of the first type of plate 10A differs from the pattern of unstacking pad 72 of the plate of the second type 10B by a rotation of the symmetrical structure in a plane of the surface of the apex of the cone. In the example, the pattern is rotated at an angle of 90 °.

La Figure 16 représente une coupe partielle laquelle illustre schématiquement un empilement de quatre plateaux intercalaires 10A, 10B, 10A, 10B selon ce troisième mode de réalisation de l'invention.The Figure 16 represents a partial section which schematically illustrates a stack of four intermediate plates 10A, 10B, 10A, 10B according to this third embodiment of the invention.

Pour fabriquer de tels plateaux intercalaires un exemple de méthode de fabrication comporte des étapes de formages successifs. Selon une première étape, un plot de dépilage est créé dans un plateau intercalaire d'un premier type comportant un motif ayant une structure symétrique. Selon une deuxième étape, un plot de dépilage est créé dans un plateau intercalaire d'un second type par une rotation de la structure symétrique du même motif dans un plan de ladite surface. Selon une troisième étape, plusieurs plateaux intercalaires du premier et du second type sont empilés selon une direction verticale de manière alternée.To manufacture such intermediate trays an example of a manufacturing method comprises successive forming steps. In a first step, an unstacking pad is created in a spacer plate of a first type having a pattern having a symmetrical structure. In a second step, an unstacking pad is created in a spacer plate of a second type by rotating the symmetrical structure of the same pattern in a plane of said surface. In a third step, a plurality of intermediate plates of the first and second type are stacked in a vertical direction alternately.

Avec l'invention, il est possible d'utiliser un moule de formage à mouvement unique lequel comporte une partie destinée à former lesdits plots de dépilage. Cette partie de moule est tournée d'un angle de rotation déterminé entre deux formages successifs afin de produire alternativement les deux types de plateaux intercalaires.With the invention, it is possible to use a single-movement forming mold which comprises a portion intended to form said unstacking studs. This mold part is rotated by a determined rotation angle between two successive formations to produce alternately the two types of intermediate plates.

Il ressort donc clairement les avantages suivants de la méthode de fabrication et des plateaux intercalaires selon l'invention décrite ci-dessus:

  • ■ les plateaux intercalaires restent bien plans en raison des multiples zones de report de charge créées par les motifs aux sommets des cônes;
  • ■ les plateaux intercalaires se détachent bien les uns des autres sans coincement possible entre les deux types en alternance;
  • ■ un gain en temps et en coût de fabrication par l'utilisation d'un moule à mouvement unique; et
  • ■ un gain à l'utilisation en terme d'efficacité de transport, de temps et de manutention lors du conditionnement car une palette peux comporter un nombre de plateaux intercalaires substantiellement plus important (par exemple 1000 plateaux intercalaires contre 500 plateaux intercalaires pour l'art antérieur).
It is therefore clearly apparent the following advantages of the method of manufacture and the intermediate trays according to the invention described above:
  • ■ the spacer trays remain flat because of the multiple load bearing areas created by the patterns at the tips of the cones;
  • ■ the spacer plates are detached well from each other without possible wedging between the two types alternately;
  • ■ a gain in time and cost of manufacture by the use of a single-movement mold; and
  • ■ a gain in use in terms of transport efficiency, time and handling during packaging because a pallet may have a substantially larger number of intermediate trays (for example 1000 intermediate trays versus 500 intermediate trays for the art prior).

Les Figures et leurs descriptions faites ci-dessus illustrent l'invention plutôt qu'elles ne la limitent. En particulier, l'invention vient d'être décrite en relation avec quelques exemples de mode de réalisation montrant différents motifs à structure symétrique. Bien évidemment d'autres motifs sont envisageables dans le cadre de l'invention pour autant que la rotation de la structure symétrique du motif dans un plan permette de créer une zone de report de charge lorsqu'une pluralité de plateaux intercalaires du premier et du second type sont empilés selon une direction verticale de manière alternée. Par exemple, un segment, deux segments droits se croisant à angle quelconque sensiblement en leurs centres, une forme en 8, un demi-cercle peuvent également convenir. Egalement, l'invention vient d'être décrite en relation avec un exemple particulier d'application de conditionnement de bouteille. Néanmoins, il est évident pour un homme du métier que l'invention peut être étendue à d'autres applications, de manière générale à toutes applications nécessitant le conditionnement horizontal et vertical de pièces en faisant usage de plateaux intercalaires. Cela peut être par exemple le cas dans tous types d'industries: automobile, aéronautique, parfumerie, agroalimentaire, etc...The figures and their descriptions made above illustrate the invention rather than limiting it. In particular, the invention has just been described in connection with a few exemplary embodiments showing different patterns with symmetrical structure. Of course other reasons are conceivable within the scope of the invention provided that the rotation of the symmetrical structure of the pattern in a plane allows to create a load transfer zone when a plurality of intermediate plates of the first and second type are stacked in a vertical direction alternately. For example, a segment, two straight segments intersecting at any angle substantially in their centers, a shape in 8, a semicircle may also be suitable. Also, the invention has just been described in connection with a particular example of bottle packaging application. Nevertheless, it is obvious to one skilled in the art that the invention can be extended to other applications, generally to all applications requiring the horizontal and vertical packaging of parts by making use of interposed trays. This can be for example the case in all types of industries: automobile, aeronautics, perfumery, food industry, etc ...
