Abstract

The method for the assembly of the feet of a cardboard pallet uses a connection collar washer (1). The washer is made of high resistance compacted cardboard with trapezoidal tabs (2) pre-cut by die stamping (3) and folded in a curved manner (4) perpendicular to the pallet plane (5). The lower annular part of the washer is applied against the pallet surface and the tabs are fixed to the internal face of the base (6) by a sleeve (7). The diameter of the hole (8) made in the pallet plane for the passage of the tabs and the internal diameter of the base are identical to allow the base area (13) to be supported on the pallet plane without malformation.

Description

La présente invention concerne un procédé d'assemblage de pied de palette cylindrique, réalisé 100% en carton, entièrement recyclable, qui est effectué à l'aide d'une pièce de liaison, dite rondelle à collerette, conformée en carton compact à haute résistance, avec des languettes de forme trapézoïdale qui sont prédécoupées par matriçage, et pliées de façon incurvée, perpendiculairement au plan de la palette, la partie annulaire plane de la rondelle est appliquée sur la surface supérieure du plan de palette, alors que les languettes incurvées sont solidaires de la force interne du piétement, par le coincement d'un manchon de dimensions appropriées, qui est enfoncé en force, dans la partie centrale de la rondelle qui est prédécoupée pour former les languettes.The present invention relates to a cylindrical pallet foot assembly process, made of 100% cardboard, fully recyclable, which is carried out using a connecting piece, known as a flange washer, shaped into compact cardboard with high resistance. , with trapezoidal tabs which are pre-cut by die-stamping, and bent in a curved manner, perpendicular to the plane of the pallet, the planar annular part of the washer is applied to the upper surface of the pallet plane, while the curved tabs are integral with the internal force of the base, by the wedging of a sleeve of appropriate dimensions, which is forcibly pressed into the central part of the washer which is pre-cut to form the tongues.

Le brevet US n" 2,528,413, décrit un procédé de fabrication de palettes, dans lequel on a prévu de réaliser directement dans le plan de la palette en carton ondulé, un prédécoupage des languettes trapézoïdales qui sont destinées à être solidaires de la face interne du piétement par collage.US Pat. No. 2,528,413 describes a method of manufacturing pallets, in which provision has been made, directly in the plane of the corrugated cardboard pallet, for precutting the trapezoidal tongues which are intended to be integral with the internal face of the base. by collage.

Cette technique est également décrite ou montrée dans d'autres documents, notamment dans les brevets US n" 4,244,766, n" 4,487,136, nO 4,850,284, anglais n" 1 455 197, français
n" 2 569 659, n" 2 706 356, dans lesquels on remarque l'aménagement de languettes directement prédécoupées par matriçage, dans le plan de la palette en carton ondulé.This technique is also described or shown in other documents, in particular in US patents n "4,244,766, n" 4,487,136, nO 4,850,284, English n "1 455 197, French
n "2,569,659, n" 2,706,356, in which we note the arrangement of tabs directly precut by die-stamping, in the plane of the corrugated cardboard pallet.

Cette technique présente cependant l'inconvénient, de ce que le plan de palette en carton ondulé, comporte une zone de moindre épaisseur, à l'endroit du pli perpendiculaire des languettes incurvées, ce qui a pour effet de le fragiliser à cet endroit, et de le rendre vulnérable lors de chocs latéraux sur la palette.This technique has the disadvantage, however, that the corrugated cardboard plane comprises a zone of reduced thickness, at the location of the perpendicular fold of the curved tongues, which has the effect of weakening it at this location, and make it vulnerable during side impact on the pallet.

11 n'est pas rare de constater le sectionnement du plan de palette à cet endroit ; de même, on constate l'écrasement et l'arrachement du carton ondulé, lors de la conformation des languettes incurvées, lorsque le manchon est enfoncé en force, dans les piétements utilisant cette technique. It is not uncommon to see the sectioning of the pallet plane at this location; Similarly, there is the crushing and tearing of the corrugated cardboard, during the conformation of the curved tongues, when the sleeve is pressed in force, in the legs using this technique.

La présente invention propose un procédé d'assemblage de pied de palette, réalisé 100% en carton, qui supprime la conformation directe des languettes dans le plan de palette, en utilisant un autre matériau que le carton ondulé, comme moyen de liaison entre le plan de palette et le piétement.The present invention provides a method of assembling a pallet foot, made 100% of cardboard, which eliminates the direct conformation of the tongues in the pallet plane, using a material other than corrugated cardboard, as a means of connection between the plane. of pallet and the base.

Pour ce fiure, on utilise une rondelle à collerette en carton compact à haute résistance, conformée avec des languettes de forme trapézoïdale qui sont prédécoupées par matriçage, et pliées de façon incurvée, perpendiculairement au plan de la palette, pour être bloquées à l'aide d'un manchon, qui est enfoncé en force, dans la partie centrale de la rondelle.For this fiure, a washer is used with a flange made of high-strength compact cardboard, shaped with trapezoidal tabs which are die-cut, and bent curved, perpendicular to the plane of the pallet, to be locked using a sleeve, which is pressed into force, in the central part of the washer.

La solidarité entre le plan de palette, qui peut toujours être réalisé en carton ondulé ou en carton en nid d'abeille, et le piétement en carton spiralé, s'en trouve donc considérablement améliorée, par rapport aux techniques de l'art antérieur.The solidarity between the pallet plane, which can always be made of corrugated cardboard or of honeycomb cardboard, and the base of spiral cardboard, is therefore considerably improved, compared with the techniques of the prior art.

D'autre part, la mise en oeuvre du procédé d'assemblage se trouvera simplifiée pour des palettes de forme spécifique, puisqu'il suffira de prévoir dans le plan de la palette une pluralité de trous, à des emplacements appropriés qui seront disposés en fonction de la charge à supporter.On the other hand, the implementation of the assembly process will be simplified for pallets of specific shape, since it will suffice to provide in the plane of the pallet a plurality of holes, at suitable locations which will be arranged in function of the load to bear.

Dans ce cas, la palette pourra être assemblée manuellement, en fonction des besoins propres à chaque utilisateur, à l'aide d'un emporte-pièce pour faire les trous dans le plan de palette, et d'un outil cylindrique comportant un épaulement, pour enfoncer le manchon, avec un maillet.In this case, the pallet can be assembled manually, according to the specific needs of each user, using a cookie cutter to make the holes in the pallet plane, and a cylindrical tool comprising a shoulder, to hammer in the sleeve with a mallet.

Selon l'invention, les éléments du piétement sont réalisés en carton spiralé pour le piétement et le manchon, la rondelle à collerette est réalisée en carton compact à haute résistance, alors que le plan de palette pourra être réalisé en carton ondulé, en carton en nid d'abeille ou en tout autre matériau présentant l'avantage d'une plus grande rigidité linéaire par rapport au carton ondulé.According to the invention, the legs of the legs are made of spiral cardboard for the legs and the sleeve, the flange washer is made of compact cardboard with high resistance, while the pallet plane can be made of corrugated cardboard, cardboard honeycomb or any other material having the advantage of greater linear rigidity compared to corrugated cardboard.

De façon classique, la technique d'assemblage du pied de palette, pourra être mise en oeuvre pour fabriquer des palettes comportant un plan supérieur et un plan inférieur, pour ce faire, les deux plans seront superposés, et les trous effectués simultanément à l'emporte-pièce.Conventionally, the technique of assembling the base of the pallet may be used to manufacture pallets comprising an upper plane and a lower plane, to do this, the two planes will be superimposed, and the holes made simultaneously with the cookie cutter.

L'invention présente un avantage économique considérable par rapport aux palettes en bois, construites de façon traditionnelle ; en outre, elle présente l'avantage d'être réalisée en monomatériau, entièrement recyclable.The invention has a considerable economic advantage over wooden pallets, built in the traditional way; in addition, it has the advantage of being made of single material, fully recyclable.

L'invention sera mieux comprise à l'aide de la description détaillée et des dessins annexés dans lesquels, la figure 1 représente le pied de palette, en vue éclatée, prêt à être assemblé à l'aide d'un outil, la figure 2 représente une palette en perspective, réalisée avec des pieds de palette, selon l'invention, la figure 3 représente une palette en perspective, réalisée avec des pieds de palette, selon l'invention, et avec des manchons ayant une hauteur suffisante pour servir dans les angles, de montant de soutènement à un filet ou à des faces en carton, et pour servir de support à la P.L.V. (publicité sur le lieu de vente).The invention will be better understood using the detailed description and the appended drawings in which, FIG. 1 represents the pallet base, in exploded view, ready to be assembled using a tool, FIG. 2 represents a pallet in perspective, produced with pallet feet, according to the invention, FIG. 3 represents a pallet in perspective, produced with pallet feet, according to the invention, and with sleeves having a sufficient height to be used in the angles, from the support upright to a net or to cardboard faces, and to serve as a support for the POS (advertising at the point of sale).

Selon l'invention, le pied de palette est réalisé avec un piétement en carton spiralé (6), que l'on pose verticalement, dans l'axe du passage d'un trou (8), réalisé avec un emporte-pièce dans le plan de la palette (5), ayant un diamètre rigoureusement identique au diamètre interne du piétement (6), afin d'éviter le déport dudit piétement sur ledit plan.According to the invention, the pallet base is produced with a spiral cardboard base (6), which is placed vertically, in the axis of the passage of a hole (8), produced with a cookie cutter in the plane of the pallet (5), having a diameter strictly identical to the internal diameter of the base (6), in order to avoid the offset of said base on said plane.

Une rondelle à collerette (1), en carton compact à haute résistance, est conformée avec des languettes de forme trapézoïdale (2), qui sont prédécoupées par matriçage (3), et pliées de façon incurvée (4), perpendiculairement au plan de la palette, la partie annulaire plane de la rondelle (9) est alignée dans l'axe du piétement, pour être appliquée sur la surface supérieure du plan de palette (5), simultanément à l'introduction des languettes incurvées (2) dans le plan de la palette et dans le piétement (6).A flange washer (1), made of compact high-strength cardboard, is shaped with trapezoidal tabs (2), which are pre-cut by die-stamping (3), and bent in a curved manner (4), perpendicular to the plane of the pallet, the flat annular part of the washer (9) is aligned in the axis of the base, to be applied to the upper surface of the pallet plane (5), simultaneously with the introduction of the curved tongues (2) in the plane of the pallet and in the base (6).

Pour ce faire, on a prévu que les languettes incurvées (2), après conformation, présentent un angle de pliage légèrement aigu par rapport à l'axe du piétement, ce qui permet à l'opérateur de les introduire avec une grande facilité, dans le trou (8) du plan de la palette et à l'intérieur du piétement (6).To do this, provision has been made for the curved tongues (2), after conformation, to have a slightly acute bending angle relative to the axis of the base, which allows the operator to insert them with great ease, into the hole (8) in the plane of the pallet and inside the base (6).

Les languettes incurvées (2) sont ensuite rendues solidaires de la face interne du piétement, à l'aide d'un manchon en carton spiralé (7), qui présente des dimensions appropriées, pour être enfoncé en force, dans la partie intérieure de la rondelle (1), prédécoupée pour former les languettes.The curved tongues (2) are then made integral with the internal face of the base, using a spiral cardboard sleeve (7), which has suitable dimensions, to be pressed into force, in the inner part of the washer (1), pre-cut to form the tabs.

Selon la technique décrite et une variante de l'invention, la partie inférieure de la rondelle à collerette (1) pourra être auto-adhésive, afin que celle-ci puisse adhérer dans un premier temps, sur le plan de palette à partir de sa partie annulaire inférieure (9), et dans un second temps, sur la partie interne du piétement, à partir de la partie inférieure des languettes (14), lorsque le manchon (7) sera enfoncé.According to the technique described and a variant of the invention, the lower part of the flange washer (1) can be self-adhesive, so that it can adhere first, on the pallet plane from its lower annular part (9), and then, on the internal part of the base, from the lower part of the tongues (14), when the sleeve (7) is pressed.

Le manchon (7) sera positionné sur la partie centrale de la rondelle à collerette prédécoupée (4), pour être enfoncé manuellement ou mécaniquement à l'aide d'un outil (10), dont l'épaulement (11) sera de dimension suffisante pour venir en appui sur le champ du manchon (12) et pour déborder en butée sur le champ du piétement (13).The sleeve (7) will be positioned on the central part of the pre-cut collar washer (4), to be pressed manually or mechanically using a tool (10), the shoulder (11) of which is sufficient to come into abutment on the field of the sleeve (12) and to overflow in abutment on the field of the base (13).

Selon une autre variante de l'invention, il sera possible de prévoir un piétement et un manchon de forme tronconique, afin de permettre l'empilage des palettes les unes dans les autres.According to another variant of the invention, it will be possible to provide a base and a frustoconical sleeve, in order to allow the pallets to be stacked one inside the other.

L'invention est particulièrement utilisée dans la fabrication de palettes réalisées 100% en carton, entièrement recyclables. The invention is particularly used in the manufacture of pallets made 100% of cardboard, fully recyclable.
