Abstract

The objective of the invention is to provide a pallet which has a smooth outer surface free from any roughness (cross-grooving or external reinforcements), made of synthetic material, and high rigidity and which can be manufactured conveniently and at low cost. This pallet comprises a rigid internal structure 1, preferably consisting of a standard pallet made of wood, cardboard, metal, synthetic material or a combination of these various materials. Around this structure an enclosure 10 made of synthetic material is produced by a rotary moulding or injection moulding process. The pallet thus obtained can be subjected to washing, decontamination or sterilisation operations, in order to be employed in environments requiring a particular cleanliness.

Description

PALETTE DESTINEE AU TRANSPORT ET AU STOCKAGE DE PIECES
OU DE RECIPIENTS, ET SON PROCEDE DE FABRICATION.PALLET FOR THE TRANSPORT AND STORAGE OF PARTS
OR CONTAINERS, AND ITS MANUFACTURING METHOD.

La présente invention concerne une palette destinée au transport et au stockage de pièces ou de récipients et pourvue d'une surface extérieure en matière synthétique. L'invention concerne également un procédé de fabrication d'une telle palette.The present invention relates to a pallet intended for the transport and storage of parts or containers and provided with an external surface of synthetic material. The invention also relates to a method of manufacturing such a pallet.

Les palettes ordinaires destinées au transport et au stockage de pièces ou de récipients sont généralement en bois. On connaît également des palettes de ce genre qui sont réalisées en carton.Ordinary pallets intended for the transport and storage of parts or containers are generally made of wood. Pallets of this kind are also known which are made of cardboard.

Toutefois, comme ces matériaux peuvent facilement être salis, contaminés ou détériorés, notamment par des liquides, des poudres, des champignons ou des bactéries, on ne peut pas employer ces palettes pour certains usages ou dans certains milieux exigeant une grande propreté, par exemple dans des hôpitaux, des buanderies ou des ateliers de fabrication de produits délicats, ainsi que dans les industries agro-alimentaires telles que biscuiteries, chocolateries, boucheries, etc.... Il faut alors disposer de palettes dont la surface est à la fois peu absorbante, lavable et résistante à l'abrasion.However, as these materials can easily be soiled, contaminated or deteriorated, in particular by liquids, powders, fungi or bacteria, these pallets cannot be used for certain uses or in certain environments requiring great cleanliness, for example in hospitals, laundries or workshops for manufacturing delicate products, as well as in the agro-food industries such as biscuit factories, chocolate factories, butchers, etc. It is then necessary to have pallets whose surface is both not very absorbent , washable and abrasion resistant.

Pour résoudre ce problème, on a créé des palettes métalliques et des palettes en matière synthétique. Les palettes métalliques sont peu utilisées parce qu'elles sont soit lourdes, ou trop chères. Il existe différents types de palettes en matière synthétique, dont les avantages et les inconvénients dépendent du procédé de fabrication utilisé. Un premier type comprend les palettes moulées par injection.To solve this problem, metallic pallets and plastic pallets have been created. Metal pallets are little used because they are either heavy, or too expensive. There are different types of plastic pallets, the advantages and disadvantages of which depend on the manufacturing process used. A first type includes injection molded pallets.

Ce procédé est particulièrement cher, à cause du coût très élevé des moules et de la grande quantité de matière synthétique qui est nécessaire pour obtenir des palettes suffisamment rigides. On peut réaliser des palettes à double paroi, donc beaucoup plus légères, par le procédé de rotomoulage qui a aussi l'avantage de nécessiter un équipement de fabrication beaucoup moins coûteux que le procédé par injection. Comme les parois sont relativement minces et flexibles, elles doivent être liées l'une à l'autre au moyen de renfoncements généralement coniques prévus dans l'une des parois.This process is particularly expensive, because of the very high cost of the molds and the large quantity of synthetic material which is necessary to obtain sufficiently rigid pallets. Double-walled pallets, which are therefore much lighter, can be produced by the rotational molding process which also has the advantage of requiring much less expensive manufacturing equipment than the injection process. As the walls are relatively thin and flexible, they must be connected to each other by means of generally conical recesses provided in one of the walls.

Néanmoins, les palettes de ce genre ont une rigidité et une résistance qui sont assez faibles et qui limitent leur utilisation à de faibles charges. Un troisième procédé consiste à réaliser par rotomoulage une enveloppe en matière synthétique rigide qui définit la surface extérieure de la palette, puis à remplir le vide intérieur de cette enveloppe par injection d'une mousse synthétique devenant rigide, par exemple à base de polyuréthane, qui assurera une liaison convenable entre les parois opposées et contribuera ainsi à leur stabilité. L'inconvénient de ce procédé est son coût, du fait qu'il nécessite deux opérations successives, et que la mousse est relativement chère, de même que l'opération d'injection.Nevertheless, pallets of this kind have a rigidity and a resistance which are rather weak and which limit their use at low loads. A third method consists in making a rigid plastic envelope by rotational molding which defines the outer surface of the pallet, then filling the interior void of this envelope by injecting a synthetic foam which becomes rigid, for example based on polyurethane, which will ensure a suitable connection between the opposite walls and thus contribute to their stability. The disadvantage of this process is its cost, because it requires two successive operations, and that the foam is relatively expensive, as is the injection operation.

Par conséquent, la présente invention a pour but de permettre de fabriquer, d'une manière relativement peu coûteuse, une palette ayant une surface extérieure en matière synthétique et une rigidité comparable à celle des palettes ordinaires.Consequently, the object of the present invention is to make it possible to manufacture, in a relatively inexpensive manner, a pallet having an outer surface of synthetic material and a rigidity comparable to that of ordinary pallets.

Dans ce but, le procédé selon l'invention est caractérisé en ce que l'on réalise une enveloppe rigide ou semi-rigide en matière synthétique autour d'une structure intérieure rigide constituée par un élément préfabriqué.For this purpose, the method according to the invention is characterized in that a rigid or semi-rigid envelope of synthetic material is produced around a rigid interior structure constituted by a prefabricated element.

Cette structure intérieure peut être en bois et/ou en matériaux à base de bois et/ou en d'autres matériaux tels que des matières synthétiques ou métalliques. Dans d'autres réalisations, elle peut être en carton ou comporter des pièces en carton combinées avec d'autres pièces. En particulier, la structure intérieure peut être constituée directement par une palette standard, notamment en bois ou en carton. On utilise ainsi une structure intérieure qui est peu coûteuse, rigide, assez légère, et en outre disponible dans le commerce en grande quantité et dans toutes les dimensions nécessaires. This internal structure can be made of wood and / or of wood-based materials and / or of other materials such as synthetic or metallic materials. In other embodiments, it can be made of cardboard or include cardboard parts combined with other parts. In particular, the interior structure can be constituted directly by a standard pallet, in particular in wood or cardboard. An internal structure is thus used which is inexpensive, rigid, fairly light, and also commercially available in large quantities and in all the necessary dimensions.

Sur cette structure, I'enveloppe en matière synthétique est réalisée de préférence par rotomoulage, donc avec un équipement peu onéreux. L'enveloppe ainsi obtenue n'adhère généralement pas à la structure intérieure sur toute sa surface, mais ce n'est pas gênant car elle ne sert pratiquement que d'élément protecteur contre les contaminations extérieures, les efforts mécaniques étant supportés par la structure intérieure. Dans une autre forme du procédé selon l'invention, on peut réaliser l'enveloppe par surmoulage de la structure intérieure par injection.On this structure, the plastic envelope is preferably produced by rotational molding, therefore with inexpensive equipment. The envelope thus obtained generally does not adhere to the internal structure over its entire surface, but this is not a problem since it practically only serves as a protective element against external contamination, the mechanical forces being supported by the internal structure . In another form of the method according to the invention, the envelope can be produced by overmolding the interior structure by injection.

Une palette selon l'invention est caractérisée en ce qu'elle comprend une structure intérieure rigide et une enveloppe rigide ou semi-rigide en matière synthétique entourant cette structure. De préférence, la structure intérieure comprend un ou plusieurs des matériaux suivants: bois, carton, matériaux à base de bois, tels que le bois contreplaqué ou le bois aggloméré ainsi qu'en métal ou matière synthétique. L'enveloppe peut être réalisée en polyéthylène, en chlorure de polyvinyle ou en toute autre matière synthétique appropriée.A pallet according to the invention is characterized in that it comprises a rigid interior structure and a rigid or semi-rigid envelope of synthetic material surrounding this structure. Preferably, the interior structure comprises one or more of the following materials: wood, cardboard, wood-based materials, such as plywood or chipboard, as well as metal or synthetic material. The envelope can be made of polyethylene, polyvinyl chloride or any other suitable synthetic material.

On décrira ci-dessous un exemple de réalisation de l'invention, en référence aux dessins annexés, dans lesquels
La fig. 1 représente en perspective une palette standard en bois, destinée à former l'ossature intérieure d'une palette selon l'invention, et la fig. 2 est une vue partielle en coupe verticale d'une palette selon l'invention, suivant la ligne ll-ll de la fig.l.An exemplary embodiment of the invention will be described below, with reference to the accompanying drawings, in which
Fig. 1 shows in perspective a standard wooden pallet, intended to form the internal framework of a pallet according to the invention, and FIG. 2 is a partial view in vertical section of a pallet according to the invention, along the line ll-ll of fig.l.

Dans le présent exemple, pour former la structure intérieure de la palette selon l'invention, on choisit un modèle de palette standard en bois ayant la capacité de charge et les dimensions voulues. De manière connue, cette palette 1 est construite par collage et agrafage d'éléments en bois tels que des planches 2, 3 et des plots 5 constituant des pieds. Bien entendu, certains de ces éléments peuvent être faits d'autres matériaux à base de bois, par exemple des panneaux en contreplaqué ou en aggloméré, des plots en aggloméré de sciure, en métal ou en matière synthétique, etc....In the present example, to form the internal structure of the pallet according to the invention, a standard wooden pallet model is chosen having the load capacity and the desired dimensions. In a known manner, this pallet 1 is constructed by gluing and stapling wooden elements such as boards 2, 3 and studs 5 constituting feet. Of course, some of these elements can be made of other wood-based materials, for example plywood or chipboard panels, blocks of sawdust chipboard, metal or synthetic material, etc.

Pour réaliser l'enveloppe, on utilise un moule de rotomoulage dont les dimensions intérieures dépassent de quelques millimètres les dimensions extérieures de la palette en bois. On équipe celle-ci de cales appropriées (non représentées), de manière qu'elle puisse être maintenue à une faible distance des parois du moule sur tout son pourtour, ce qui permet de fabriquer par rotomoulage une enveloppe 10 en matière synthétique qui entoure complètement la palette 1.To make the envelope, a rotational molding mold is used whose internal dimensions exceed the external dimensions of the wooden pallet by a few millimeters. This is fitted with suitable shims (not shown), so that it can be kept a short distance from the walls of the mold around its entire circumference, which makes it possible to manufacture by rotational molding a casing 10 of synthetic material which completely surrounds palette 1.

Dans le cas présent, où les planches supérieures 2 de la palette en bois sont séparées par des intervalles 6, on choisira une matière synthétique relativement résistante et rigide pour réaliser l'envelop- pe 10, par exemple du polyéthylène. Si l'on veut réaliser une palette relativement légère tout en ayant une surface supérieure suffisamment rigide, on peut prévoir des planches supérieures 2 plus espacées et éventuellement remplir les intervalles 6 au moyen d'éléments préfabriqués en carton ou en mousse synthétique.In the present case, where the upper planks 2 of the wooden pallet are separated by intervals 6, a relatively strong and rigid synthetic material will be chosen to make the envelope 10, for example polyethylene. If a relatively light pallet is to be produced while having a sufficiently rigid upper surface, it is possible to provide upper boards 2 more spaced apart and optionally fill the intervals 6 by means of prefabricated elements of cardboard or synthetic foam.

Une palette ainsi réalisée présente les mêmes propriétés de salubrité et d'imperméabilité que les palettes réalisées entièrement en matière synthétique. En particulier, on peut facilement la laver, la détacher, la désinfecter ou la stériliser. Pour certaines utilisations spécifiques, le choix d'une matière synthétique appropriée permet d'obtenir une palette qui n'est pas altérée par une fuite accidentelle d'un produit contenu dans un récipient qu'elle supporte. D'autre part, on peut fabriquer avec un moule de rotomoulage des palettes ayant des capacités de charge ou des poids différents, simplement en adaptant les caractéristiques de l'ossature intérieure.A pallet thus produced has the same salubrity and impermeability properties as pallets made entirely of synthetic material. In particular, it can easily be washed, detached, disinfected or sterilized. For certain specific uses, the choice of an appropriate synthetic material makes it possible to obtain a pallet which is not altered by an accidental leak of a product contained in a container which it supports. On the other hand, pallets having different load capacities or weights can be made with a rotational molding mold, simply by adapting the characteristics of the internal framework.

La présente invention n'est pas limitée aux formes de réalisation décrites, mais s'étend à diverses variantes évidentes pour l'homme de l'art. The present invention is not limited to the embodiments described, but extends to various variants obvious to those skilled in the art.
