Description

"Procédé de palettisation avec renfort de résistance à la compression" "Palletizing process with reinforcement of compressive strength"
L'invention concerne un procédé de palettisation avec renfort de résistance à la compression et le dispositif permettant de mettre en oeuvre ce procédé.The invention relates to a palletizing process with reinforcement of compressive strength and the device for implementing this process.
Les procédés de palettisation connus permettent le stockage, le transport et la manutention de lots de produits emballés et empilés les uns sur les autres. II est donc nécessaire d'avoir des emballages dont la résistance à la compression supporte le poids de 1'ensemble des produits se trouvant empilés au dessus d'eux. La résistance à la compression de chaque emballage est fortement liée à la quantité de matière première utilisée qui est la plupart du temps du carton réalisé à partir de pâte à papier ou tout autre matériau. Un but de l'invention est de fournir un procédé de palettisation avec renfort de résistance à la compression qui permette de diminuer la quantité de matière première nécessaire pour la fabrication des emballages tout en gardant une charge en palettisation complète identique. Il faut également que les emballages situés dans la partie inférieure de la palette chargée ne s'affaissent pas. Conformément à l'invention, ce but est atteint par un procédé de palettisation avec renfort de résistance à la compression qui comprend les étapes suivantes:Known palletizing processes allow the storage, transport and handling of batches of packaged products stacked on top of each other. It is therefore necessary to have packages whose compressive strength supports the weight of all the products being stacked above them. The compressive strength of each package is strongly linked to the amount of raw material used, which is mostly cardboard made from paper pulp or any other material. An object of the invention is to provide a palletizing process with reinforcement of compressive strength which makes it possible to reduce the quantity of raw material necessary for the manufacture of packaging while keeping an identical full palletizing load. The packaging at the bottom of the loaded pallet must also not collapse. According to the invention, this object is achieved by a palletizing process with reinforcement of compressive strength which comprises the following steps:
- on fournit une palette, de largeur LI et de profondeur PI, destinée à recevoir une charge de hauteur totale Hl,- a pallet is provided, of width LI and depth PI, intended to receive a load of total height Hl,
- on fournit des emballages de hauteur H2, chaque emballage ayant au moins un trou traversant l'emballage de part en part sur la hauteur de l'emballage, le trou étant issu au moins d'une perforation inférieure, - on fournit des piliers de renfort à la compression dont la hauteur H3 est un multiple de la hauteur H2 des emballages, les piliers pouvant être insérés au moins dans certains des trous,- H2 height packages are provided, each package having at least one hole passing through the package right through the height of the package, the hole being at least from a lower perforation, - pillars are provided. compression reinforcement whose height H3 is a multiple of the height H2 of the packages, the pillars can be inserted at least in some of the holes,
- on fournit au moins un plateau intercalaire,- at least one intermediate plate is provided,
- on empile une première série d'emballages sur la palette, les emballages constituant un ensemble inférieur d'emballages, de façon que les trous soient alignés et de sorte que la hauteur de l'ensemble inférieur d'emballages soit égale à la hauteur H3 des piliers, - on insère au moins trois des piliers dans des trous de l'ensemble inférieur d'emballages pouvant servir de guide pour les piliers, de telle sorte que les piliers soient verticaux,- A first series of packages is stacked on the pallet, the packages constituting a lower package assembly, so that the holes are aligned and so that the height of the lower package assembly is equal to the height H3 pillars, - at least three of the pillars are inserted into holes in the lower package assembly which can serve as a guide for the pillars, so that the pillars are vertical,
- on pose le plateau intercalaire sur l'ensemble inférieur d'emballage de sorte que le plateau repose sur l'extrémité supérieure des piliers, etthe intermediate plate is placed on the lower packaging assembly so that the plate rests on the upper end of the pillars, and
- on empile une deuxième série d'emballages sur le plateau intercalaire, les emballages constituant un ensemble supérieur d'emballages. II est avantageusement prévu que les emballages sont des parallélépipèdes rectangles et que l'on insère quatre piliers dans des trous situés dans les zones d'angles de l'ensemble inférieur d'emballages.- A second series of packages is stacked on the intermediate plate, the packages constituting an upper set of packages. It is advantageously provided that the packages are rectangular parallelepipeds and that four pillars are inserted into holes located in the corner areas of the lower package assembly.
Grâce à ce procédé on obtient de façon simple le renforcement de résistance à la compression verticale d'un ensemble d'emballages empilés dans la partie inférieure d'une palette chargée.Thanks to this process, the reinforcement of resistance to vertical compression of a set of packages stacked in the lower part of a loaded pallet is obtained in a simple manner.
Selon une caractéristique avantageuse, tous les emballages comportent une pluralité de trous: certains de ces trous peuvent servir de guide pour les piliers alors que les autres trous servent à l'aération des emballages empilés et le plateau intercalaire est perforé de sorte que des parties évidées du plateau sont au moins partiellement en regard des trous servant à l'aération des emballages.According to an advantageous characteristic, all the packages have a plurality of holes: some of these holes can serve as a guide for the pillars while the other holes serve to ventilate the stacked packages and the intermediate plate is perforated so that hollowed out parts from the plateau are at least partially opposite the holes used for ventilating the packages.
Ainsi une aération de l'intérieur des emballages est possible du fait que l'air peut circuler par les trous d'aération qui forment entre eux des cheminées d'aération verticale. Ceci est parfois indispensable lorsque les produits transportés sont des denrées périssables telles que des produits frais comme les fromages. Dans le cas du transport de certains produits périssables, les emballages utilisés jusqu'à présent sont déjà perforés en vue de l'aération indispensable à la bonne conservation de ces produits. Il est alors aisé d'appliquer le procédé de palettisation selon l'invention. On conserve la structure et la disposition sur la palette de ces emballages tout en diminuant leur composition : on utilise moins de matière première pour les emballages sans modifier la charge totale pouvant être palettisée ni le volume utile disponible pour le produit dans l'emballage.Thus ventilation of the interior of the packages is possible because air can circulate through the ventilation holes which form between them vertical ventilation chimneys. This is sometimes essential when the products transported are perishable goods such as fresh products such as cheese. In the case of the transport of certain perishable products, the packaging used until now is already perforated for the ventilation essential for the good conservation of these products. It is then easy to apply the palletizing process according to the invention. The structure and the arrangement are kept on the pallet of these packages while reducing their composition: less raw material is used for the packaging without modifying the total load that can be palletized or the useful volume available for the product in the packaging.
Un autre but de l'invention est de réaliser un dispositif de palettisation qui possède les avantages mentionnés précédemment.Another object of the invention is to provide a palletizing device which has the advantages mentioned above.
Cet autre but est réalisé grâce à un dispositif de palettisation pour l'empilement d'emballages de hauteur H2 comportant des trous traversant les emballages de part en part en direction verticale, chacun des trous étant issu au moins d'une perforation inférieure, où il est prévu: - une palette destinée à recevoir une charge de hauteur totale Hl constituée par l'ensemble des emballages empilés, des piliers de renfort de résistance à la compression dont la hauteur H3 est un multiple de la hauteur H2 des emballages et destinés à être mis en place verticalement dans des trous pouvant servir de guide de telle sorte que leur extrémité supérieure soit au niveau du bord supérieur des parois verticales des emballages qui contiennent la partie terminale supérieure des piliers, etThis other object is achieved by a palletizing device for stacking packages of height H2 comprising holes passing through the packages from side to side in a vertical direction, each of the holes coming from at least one lower perforation, where it is planned: - a pallet intended to receive a load of total height Hl constituted by all of the stacked packages, pillars of compression resistance reinforcement whose height H3 is a multiple of the height H2 of the packages and intended to be placed vertically in holes which can serve as a guide so that their upper end is at the upper edge of the vertical walls of the packages which contain the upper end part of the pillars, and
- un plateau intercalaire destiné à reposer sur l'extrémité supérieure des piliers.- an intermediate plate intended to rest on the upper end of the pillars.
Selon une caractéristique avantageuse, la hauteur H3 des piliers est égale à trois fois la hauteur H2 des emballages lorsque les emballages ont été empilés.According to an advantageous characteristic, the height H3 of the pillars is equal to three times the height H2 of the packages when the packages have been stacked.
L'invention sera mieux comprise et des caractéristiques secondaires et leurs avantages apparaîtront au cours de la description d'une réalisation donnée ci-dessous à titre d'exemple.The invention will be better understood and secondary characteristics and their advantages will become apparent during the description of an embodiment given below by way of example.
Il est entendu que la description et les dessins ne sont donnés qu'à titre indicatif et non limitatif.It is understood that the description and the drawings are given for information only and are not limiting.
Il sera fait référence aux dessins annexés dans lesquels: - la figure 1 est une perspective schématique d'une palette chargée de l'art antérieur;Reference will be made to the accompanying drawings in which: - Figure 1 is a schematic perspective of a pallet loaded with the prior art;
- la figure 2A est une perspective schématique d'un emballage empilé dans l'ensemble inférieur d'emballages au cours d'une étape intermédiaire du procédé de palettisation selon l'invention; la figure 2B est une vue du dessus de l'emballage représenté à la figure 2A;- Figure 2A is a schematic perspective of a package stacked in the lower set of packages during an intermediate step of the palletizing process according to the invention; Figure 2B is a top view of the package shown in Figure 2A;
- la figure 3 est une perspective schématique d'une étape intermédiaire dans le procédé de palettisation selon l'invention;- Figure 3 is a schematic perspective of an intermediate step in the palletizing process according to the invention;
- la figure 4 concerne une zone détaillée de la figure 3; la figure 5 représente le phénomène de fléchissement d'une face latérale d'un emballage. Conformément à la figure 1, le procédé de palettisation connu par l'art antérieur consistait à empiler de façon ordonnée des emballages 20 sur une palette de transport 10. Cette palette 10 est constituée par un socle comportant un plateau et des pieds entre lesquels est prévu le passage de la fourche de chariots élévateurs ou dispositifs analogues.- Figure 4 relates to a detailed area of Figure 3; FIG. 5 represents the phenomenon of deflection of a lateral face of a package. In accordance with FIG. 1, the palletizing process known by the prior art consisted in stacking packaging 20 in an orderly fashion on a transport pallet 10. This pallet 10 is constituted by a base comprising a tray and feet between which is provided the passage of the fork of forklifts or similar devices.
De manière classique des emballages parallélépipédiques 20 de largeur L2, de profondeur P2 et de hauteur H2 sont empilés de façon régulière pour former une charge de palettisation complète parallélépipedique de largeur LI, de profondeur PI et de hauteur Hl. La largeur LI et la profondeur PI de la charge totale sont respectivement des multiples de la largeur L2 et de la profondeur P2 des emballages 20. Pour optimiser le volume de la charge totale de chaque palette, la largeur LI et la profondeur PI de cette charge sont respectivement égales à la largeur et la profondeur de la palette 10. L'empilement des emballages 20 forme des couches successives superposées, chacun des emballages d'une couche supportant le poids des emballages situés au- dessus de lui. Par exemple si l'on se réfère à nouveau à la figure 1, chaque emballage de la couche inférieure 12 supporte tous les emballages des couches supérieures 14 qui se trouvent directement au-dessus de cet emballage.Conventionally, parallelepipedic packages 20 of width L2, depth P2 and height H2 are stacked in a regular manner to form a complete parallelepiped pallet load of width LI, depth PI and height H1. The width LI and the depth PI of the total load are respectively multiples of the width L2 and the depth P2 of the packages 20. To optimize the volume of the total load of each pallet, the width LI and the depth PI of this load are respectively equal to the width and the depth of the pallet 10. The stack of packages 20 forms successive superimposed layers, each of the packages of a layer supporting the weight of the packages located above it. For example if we refer again to Figure 1, each package of the lower layer 12 supports all the packages of the upper layers 14 which are located directly above this package.
Si on observe le besoin en résistance à la compression verticale par niveau, celui-ci décroît au fur et à mesure que la charge située au-dessus de ce niveau diminue. Cette constatation a permis de concevoir un système de renfort permettant d'assurer la résistance en compression verticale du bas de la palette chargée et ainsi de rendre possible la réduction de la composition des emballages pour l'ensemble de la palette chargée.If we observe the need for resistance to vertical compression per level, this decreases as the load located above this level decreases. This observation made it possible to design a reinforcement system making it possible to ensure the resistance in vertical compression of the bottom of the loaded pallet and thus to make possible the reduction in the composition of packaging for the entire loaded pallet.
On observe qu'à partir d'un certain niveauWe observe that from a certain level
(référencé 16 sur la figure 1) correspondant à moins d'un tiers de la hauteur Hl de la charge totale de la palette, le besoin en résistance à la compression verticale est réduit d'environ 50%.(referenced 16 in Figure 1) corresponding to less than a third of the height Hl of the total load of the pallet, the need for resistance to vertical compression is reduced by about 50%.
Conformément à l'invention, les emballages 20 sont identiques et nécessairement perforés de part en part. Un exemple de perforation est représenté à la figure 2A: au moins une perforation inférieure est située dans la paroi horizontale inférieure ou fond des emballages 20. On peut utiliser des emballages avec un fond et une paroi horizontale supérieure, dans ce cas chaque perforation inférieure se trouve en regard d'une perforation supérieure identique située dans la paroi horizontale supérieure des emballages 20.In accordance with the invention, the packages 20 are identical and necessarily perforated right through. An example of a perforation is shown in FIG. 2A: at least one lower perforation is located in the lower horizontal wall or bottom of the packages 20. It is possible to use packages with a bottom and an upper horizontal wall, in this case each lower perforation located opposite an identical upper perforation located in the upper horizontal wall of the packages 20.
Dans l'exemple représenté, les emballages 20 ne comprennent pas de paroi horizontale supérieure mais seulement un fond ou paroi horizontale inférieure et quatre parois latérales verticales. Comme on peut le voir sur les figures 2A et 2B, il y a six perforations inférieures qui sont au bord de la paroi horizontale inférieure et se prolongent dans une partie de la paroi latérale la plus large ou flanc le plus large qui est consécutif à la paroi horizontale perforée et aux perforations.In the example shown, the packages 20 do not include an upper horizontal wall but only a bottom or lower horizontal wall and four vertical side walls. As can be seen in Figures 2A and 2B, there are six lower perforations which are at the edge of the lower horizontal wall and extend into a part of the widest side wall or widest flank which is consecutive to the perforated horizontal wall and perforations.
N'ayant pas de perforations correspondantes dans une paroi horizontale supérieure, les perforations inférieures situées dans le fond des emballages 20 constituent des trous en regard les uns des autres lorsque les emballages sont empilés dans le même sens.Having no corresponding perforations in an upper horizontal wall, the lower perforations located in the bottom of the packages 20 constitute holes facing each other when the packages are stacked in the same direction.
Comme on peut le voir sur les figures 2A et 2B, le fond de chaque emballage 20 possède un axe de symétrie 26 parallèle à la largeur L2 de l'emballage et qui coupe à angle droit la profondeur P2 (ou longueur) en deux portions identiques et un centre de symétrie S situé à l'intersection des diagonales du fond rectangulaire.As can be seen in FIGS. 2A and 2B, the bottom of each package 20 has an axis of symmetry 26 parallel to the width L2 of the packaging and which cuts the depth P2 (or length) at two right angles into two identical portions and a center of symmetry S located at the intersection of the diagonals of the rectangular bottom.
Le fond de chaque emballage 20 comprend tout d'abord deux grandes perforations triangulaires 22a dont un des côtés suit le bord le plus large du fond et constitue une base de largeur C2, le grand triangle s'avançant en direction du bord opposé sur une distance B2 correspondant à la hauteur du grand triangle.The bottom of each package 20 firstly comprises two large triangular perforations 22a, one of the sides of which follows the widest edge of the bottom and forms a base of width C2, the large triangle advancing towards the opposite edge over a distance B2 corresponding to the height of the large triangle.
Les deux grandes perforations triangulaires 22a sont situées de part et d'autre de l'axe de symétrie 26. Une première perforation rectangulaire 22c est située entre les deux grandes perforations triangulaires 22a et pourrait présenter n'importe quel autre forme de contour. Une deuxième perforation rectangulaire 22c est le symétrique de la première perforation rectangulaire 22c par rapport au centre de symétrie S.The two large triangular perforations 22a are located on either side of the axis of symmetry 26. A first rectangular perforation 22c is located between the two large triangular perforations 22a and could have any other shape of contour. A second rectangular perforation 22c is the symmetrical of the first rectangular perforation 22c with respect to the center of symmetry S.
De préférence, les perforations inférieures (22a, 22b, 22c) des emballages 20 comprennent au moins une petite perforation inférieure 22b dont les dimensions sont plus petites que celles des trous 22a pouvant servir de guide pour les piliers 30 et située symétriquement à la perforation inférieure de ces trous 22a par rapport au centre de symétrie S de la paroi horizontale inférieure des emballages 20 et au moins les emballages 20 de la première couche dudit ensemble supérieur d'emballages 20b sont empilés après avoir subi une rotation de 180* autour d'un axe vertical par rapport aux emballages 20 dudit ensemble inférieur d'emballages 20a de sorte que les piliers 30 se trouvent dans l'alignement des petites perforations inférieures 22b de la première couche de l'ensemble supérieur d'emballages 20b.Preferably, the lower perforations (22a, 22b, 22c) of the packages 20 comprise at least one small lower perforation 22b whose dimensions are smaller than those of the holes 22a which can serve as a guide for the pillars 30 and located symmetrically at the lower perforation of these holes 22a relative to the center of symmetry S of the lower horizontal wall of the packages 20 and at least the packages 20 of the first layer of said upper set of packages 20b are stacked after having undergone a rotation of 180 * around a vertical axis with respect to the packages 20 of said lower set of packages 20a so that the pillars 30 are found in alignment with small lower perforations 22b of the first layer of the upper set of packages 20b.
Dans le mode de réalisation représenté, il y a, de part et d'autre de la deuxième perforation rectangulaire 22c, deux petites perforations triangulaires 22b qui sont les symétriques des grandes perforations triangulaires 22a par rapport au centre de symétrie S. Les petites perforations triangulaires 22b ont une base de largeur Cl et une hauteur Bl qui sont respectivement inférieures à la largeur C2 et à la hauteur B2 des grandes perforations triangulaires 22a.In the embodiment shown, there are, on either side of the second rectangular perforation 22c, two small triangular perforations 22b which are the symmetrics of the large triangular perforations 22a with respect to the center of symmetry S. The small triangular perforations 22b have a base of width C1 and a height Bl which are respectively less than the width C2 and the height B2 of the large triangular perforations 22a.
Lorsque deux emballages 20 sont empilés de façon inversée c'est-à-dire que l'emballage situé au dessus a subi une rotation de 180* autour d'un axe vertical par rapport à l'emballage du dessous, cette configuration permet à chacune des deux grandes perforations triangulaires 22a de l'emballage du dessous d'être alignée verticalement avec une des deux petites perforations triangulaires 22b de l'emballage situé au dessus. Dans cette configuration, en faisant la projection verticale du contour d'une grande perforation triangulaire 22a de l'emballage du dessous sur le fond de l'emballage situé au dessus, on obtient le contour tracé en pointillés sur la figure 2B. La zone de la surface du fond de l'emballage situé au dessus comprise entre le contour en pointillés et le contour de la petite perforation triangulaire 22b qui est situé en retrait par rapport audit contour en pointillés correspond à une zone portante 23 dont le rôle sera décrit plus tard.When two packages 20 are stacked in an inverted manner, that is to say that the package located above has undergone a rotation of 180 * around a vertical axis with respect to the package below, this configuration allows each of the two large triangular perforations 22a of the packaging from below to be aligned vertically with one of the two small triangular perforations 22b of the packaging located above. In this configuration, by making the vertical projection of the contour of a large triangular perforation 22a of the packaging from below on the bottom of the packaging situated above, the contour drawn in dotted lines in FIG. 2B is obtained. The area of the surface of the bottom of the package located above lying between the dotted outline and the outline of the small triangular perforation 22b which is set back with respect to said dotted outline corresponds to a bearing area 23 whose role will be described later.
Pour renforcer l'aération entre les emballages 20 empilés, chacune des deux parois latérales les plus larges possède trois perforations qui sont, dans l'exemple représenté à la figure 2A, similaires aux perforations rectangulaires 22c, situées dans 1'alignement vertical des perforations du fond de 1'emballage et débouchent à l'extrémité supérieure des parois latérales.To strengthen the ventilation between the stacked packages 20, each of the two largest side walls has three perforations which are, in the example shown in FIG. 2A, similar to the rectangular perforations 22c, situated in the vertical alignment of the perforations at the bottom of the package and open out at the upper end of the side walls.
Les grandes perforations triangulaires 22a sont dimensionnées pour permettre le passage d'un pilier 30 et les autres perforations sont destinées à ventiler l'intérieur des emballages 20. La figure 3 représente un ensemble inférieur 20a d'emballages 20 constitué par trois couches d'emballages au travers desquelles sont insérés six piliers de renfort de résistance à la compression verticale 30. On peut prévoir huit ou même davantage de piliers 30 en fonction du type d'emballage 20, du nombre de ces emballages 20 par niveau et du chargement de chacun de ces emballages.The large triangular perforations 22a are dimensioned to allow the passage of a pillar 30 and the other perforations are intended to ventilate the interior of the packages 20. FIG. 3 represents a lower set 20a of packages 20 constituted by three layers of packages through which are inserted six pillars of resistance to vertical compression resistance 30. One can provide eight or even more pillars 30 depending on the type of packaging 20, the number of these packages 20 per level and the load of each these packages.
Grâce à l'alignement des trous 22a, l'extrémité inférieure de chaque pilier 30 repose sur le plateau de la palette 10. L'extrémité supérieure de chaque pilier 30 est alors au niveau de l'extrémité supérieure des parois verticales des emballages 20 de la troisième couche ou couche supérieure de l'ensemble inférieur d'emballages 20a. On pose ensuite le plateau intercalaire 40 qui repose sur l'extrémité supérieure des piliers 30 et sur l'extrémité supérieure des parois verticales des emballages de la couche supérieure de l'ensemble inférieur d'emballages 20a. La dernière étape consiste à empiler les emballages constituant l'ensemble supérieur d'emballages 20b : ils sont inversés par rapport aux emballages de l'ensemble inférieur d'emballages 20a car ils ont subi une rotation de 180* autour d'un axe vertical par rapport aux emballages de l'ensemble inférieur d'emballages 20a.Thanks to the alignment of the holes 22a, the lower end of each pillar 30 rests on the plate of the pallet 10. The upper end of each pillar 30 is then at the level of the upper end of the vertical walls of the packages 20 of the third layer or upper layer of the lower package assembly 20a. The intermediate plate 40 is then placed which rests on the upper end of the pillars 30 and on the upper end of the vertical walls of the packages of the upper layer of the lower package assembly 20a. The last step consists of stacking the packages constituting the upper set of packages 20b: they are inverted with respect to the packages of the lower set of packages 20a because they have been rotated 180 * around an axis vertical with respect to the packages of the lower set of packages 20a.
Les piliers 30 et l'ensemble inférieur d*emballages 20a supportent le poids de l'ensemble supérieur d'emballages 20b qui sera par exemple constitué de six couches d'emballages 20. Le poids de cet ensemble supérieur d'emballages 20b est réparti sur les piliers 30 et sur le plateau intercalaire 40.The pillars 30 and the lower package assembly 20a support the weight of the upper package assembly 20b which will for example consist of six layers of packages 20. The weight of this upper package assembly 20b is distributed over the pillars 30 and on the intermediate plate 40.
Le plateau intercalaire 40 sert de butée ou d'élément de mise à niveau entre l'ensemble supérieur d'emballages 20b et l'ensemble inférieur d'emballages 20a. Les piliers 30 étant plus résistants à la compression verticale que l'ensemble inférieur d'emballages 20a, ils ne s'affaissent pas. Il faut donc que le plateau intercalaire 40 ne se déforme pas du fait de la tendance au poinçonnement par les piliers 30 qui contrebalance le poids de l'ensemble supérieur d'emballages 20b. Pour ne pas avoir à fournir un plateau intercalaire 40 ayant une composition en matière première plus importante, on a pensé à renforcer ce plateau intercalaire 40 par le fond des emballages de la couche inférieure de l'ensemble supérieur d'emballages 20b.The intermediate plate 40 serves as a stop or leveling element between the upper package assembly 20b and the lower package assembly 20a. The pillars 30 being more resistant to vertical compression than the lower set of packages 20a, they do not collapse. It is therefore necessary that the intermediate plate 40 does not deform due to the tendency to punching by the pillars 30 which counterbalances the weight of the upper set of packages 20b. So as not to have to provide an intermediate plate 40 having a greater composition of raw material, it has been thought to reinforce this intermediate plate 40 by the bottom of the packages of the lower layer of the upper set of packages 20b.
C'est le rôle de la zone portante 23 décrite précédemment : sur l'extrémité supérieure de chaque pilier 30 repose successivement le plateau intercalaire 40, une zone portante 23 constituée par une zone du fond d'un emballage puis le contenu de cet emballage et d'autres emballages empilés au dessus. On a ainsi deux épaisseurs de carton au dessus de l'extrémité supérieure de chaque pilier 30, ce qui évite toute déformation due aux piliers 30.This is the role of the bearing zone 23 described above: on the upper end of each pillar 30 successively rests the intermediate plate 40, a bearing zone 23 consisting of a zone at the bottom of a package then the contents of this package and other packaging stacked on top. There are thus two thicknesses of cardboard above the upper end of each pillar 30, which avoids any deformation due to the pillars 30.
Par ailleurs, ainsi que représenté à la figure 4, il est prévu que le contour externe des piliers 30, en section dans un plan perpendiculaire à leur hauteur H3, a un profil dont la largeur A est identique à la largeur B2 des trous 22a pouvant servir de guide pour les piliers 30. il est également possible que le contour externe des piliers 30, en section dans un plan perpendiculaire à leur hauteur H3, soit sensiblement identique au contour interne des trous 22a pouvant servir de guide pour les piliers 30. Dans le mode de réalisation préféré, (voir figures 3 et 4), les piliers 30 ont un profil en forme de V, les perforations 22a, 22b ayant un contour interne de forme triangulaire.Furthermore, as shown in Figure 4, it is expected that the outer contour of the pillars 30, in section in a plane perpendicular to their height H3, has a profile whose width A is identical to the width B2 of the holes 22a which can serve as a guide for the pillars 30. it is also possible that the external contour of the pillars 30, in section in a plane perpendicular to their height H3, ie substantially identical to the internal contour of the holes 22a which can serve as a guide for the pillars 30. In the preferred embodiment, (see FIGS. 3 and 4), the pillars 30 have a profile in the form of V, the perforations 22a, 22b having an internal contour of triangular shape.
De plus selon une caractéristique avantageuse, pour former les piliers, on découpe les parties évidées 42 dans le plateau intercalaire 40 et on forme, par pliage, les piliers 30 dans les parties découpées du plateau intercalaire 40 de façon que les zones du plateau intercalaire 40 qui reposent sur les extrémités supérieures des piliers 30 n'appartiennent pas aux parties évidées 42.In addition, according to an advantageous characteristic, to form the pillars, the hollowed-out parts 42 are cut out in the intermediate plate 40 and the pillars 30 are formed, by folding, in the cut-out parts of the intermediate plate 40 so that the zones of the intermediate plate 40 which rest on the upper ends of the pillars 30 do not belong to the recessed parts 42.
Cette solution est économique puisque le pilier 30 est réalisé à partir d'une découpe à plat avec rainages qui sera prélevée sur la plaque 40, créant simultanément la partie évidée 42 qui permet d'assurer la ventilation verticale.This solution is economical since the pillar 30 is made from a flat cut with grooves which will be taken from the plate 40, simultaneously creating the hollowed-out part 42 which makes it possible to ensure vertical ventilation.
Si l'on se reporte plus précisément à la figure 4, les dimensions des grandes perforations triangulaires 22a et celles du pilier 30 sont prévues pour que le pilier 30 épouse le contour de la perforation 22a : ceci est possible car le pilier présente une certaine élasticité du fait de sa forme en V. Ceci permet au pilier 30 d'être en butée horizontale avec les grandes perforations triangulaires 22a et ainsi de renforcer la résistance en compression verticale et la résistance à la flexion horizontale de chaque emballage de l'ensemble inférieur 20a d'emballages.If one refers more precisely to FIG. 4, the dimensions of the large triangular perforations 22a and those of the pillar 30 are provided so that the pillar 30 follows the outline of the perforation 22a: this is possible because the pillar has a certain elasticity due to its V shape. This allows the pillar 30 to be in horizontal abutment with the large triangular perforations 22a and thus to reinforce the resistance to vertical compression and resistance to horizontal bending of each package of the lower set 20a of packages.
En effet, comme représenté sur la figure 5, les flancs latéraux des emballages 20 de l'ensemble inférieur 20a d'emballages ont un contour 24 rectangulaire (traits pleins) de largeur H2 et de longueur L2 ou P2. Sans les piliers 30, sous le poids des emballages de l'ensemble supérieur 20b, la force F de compression verticale s'applique sur le flanc latéral dont les bords latéraux finissent par plier et on obtient un contour déformé vers l'intérieur ou vers l'extérieur du flanc latéral (traits en pointillés de la figure 4). Grâce aux piliers 30 les parois verticales des emballages 20 de l'ensemble inférieur 20a d'emballages résistent mieux au fléchissement.In fact, as shown in FIG. 5, the lateral flanks of the packages 20 of the lower assembly 20 a of packages have a rectangular outline 24 (solid lines) of width H2 and length L2 or P2. Without the pillars 30, under the weight of the packages of the upper assembly 20b, the force F of vertical compression is applied on the lateral flank whose lateral edges end up bending and a contour is deformed inward or inward. outside the lateral flank (dotted lines in FIG. 4). Thanks to the pillars 30, the vertical walls of the packages 20 of the lower assembly 20a of packages resist bending better.
Selon une autre caractéristique, la hauteur de 1'ensemble inférieur d'emballage 20a est au plus égale au tiers de la hauteur totale Hl des ensembles inférieur 20a et supérieur 20b d'emballages lorsque les emballages sont empilés sur la palette 10. According to another characteristic, the height of the lower packaging assembly 20a is at most equal to one third of the total height H1 of the lower assemblies 20a and upper 20b of packages when the packages are stacked on the pallet 10.
