Description

L'invention concerne les palettes comportant une base rigide pourvue de plots de supports.The invention relates to pallets comprising a rigid base provided with support pads.

Les palettes destinées à supporter une charge, au fond d'un conteneur par exemple ou à la base d'une pile de produits, sont souvent réalisées en carton et comportent des pieds élevant la base par rapport au sol de manière à laisser s'engager les fourches d'un chariot de manutention. Ces pieds peuvent être constitués par des canaux en carton comme montré dans le document FR-A-2 057 167. Cette solution présente l'inconvénient de ne pas résister à l'humidité du sol ou des fonds de caisse, et d'entraîner un affaissement du carton et de la charge. Afin d'éviter ce problème, il a été proposé, par exemple dans le document GB-A-2 089 316, de réaliser une base rigide en carton dans laquelle on forme des lignes de trous, et d'y fixer des plots de plastique servant de pieds : ces plots sont tronconiques ou prismatiques et comportent une collerette de rivetage sur le carton. Le carton subit, au voisinage de la collerette des efforts de cisaillement importants qui entraînent des risques de déchirure du carton et d'arrachement du plot, aggravés par l'humidité environnante éventuelle. De plus, ces plots ont une surface de base relativement faible, qui concentre la charge supérieure et risque de perforer le support inférieur sur laquelle ils reposent. Enfin, le montage de ces plots ne se prête pas à l'automatisation.Pallets intended to support a load, at the bottom of a container for example or at the base of a stack of products, are often made of cardboard and have feet raising the base from the ground so as to allow engagement the forks of a handling cart. These feet can be formed by cardboard channels as shown in document FR-A-2,057,167. This solution has the drawback of not resisting the humidity of the ground or of the bodywork, and of causing a sagging of cardboard and load. In order to avoid this problem, it has been proposed, for example in document GB-A-2 089 316, to make a rigid cardboard base in which lines of holes are formed, and to attach plastic pads to it serving as feet: these studs are frustoconical or prismatic and have a riveting collar on the cardboard. The cardboard undergoes, in the vicinity of the flange, significant shearing forces which involve risks of tearing of the cardboard and tearing of the stud, aggravated by the possible surrounding humidity. In addition, these pads have a relatively small base surface, which concentrates the upper load and risks perforating the lower support on which they rest. Finally, the mounting of these studs does not lend itself to automation.

L'invention a pour but de proposer un nouveau type de palette de conception économique, simple, robuste, résistant bien à l'humidité et à toutes les contraintes s'exerçant habituellement sur les palettes. L'invention vise aussi un procédé de préparation de palettes facile à mettre en oeuvre, pouvant donner lieu à la commercialisation de palettes entièrement montées, ou bien à monter.The object of the invention is to propose a new type of pallet of economic design, simple, robust, resistant to humidity and to all the stresses usually exerted on pallets. The invention also relates to a process for the preparation of pallets which is easy to implement, which may give rise to the marketing of fully assembled pallets, or else to be assembled.

Pour préparer une palette conformément à l'invention, après avoir formé des lignes de trous dans la base, on dispose au dessus d'une ligne de trous une bande de matériau défini ci-après de largeur inférieure ou égale à la largeur des trous dans le sens de la ligne, on enfonce cette bande dans les trous en ligne de façon à former des créneaux de bande, on insère dans les créneaux des patins afin de former les plots de support.To prepare a pallet according to the invention, after having formed lines of holes in the base, a strip of material defined below of width less than or equal to the width of the holes in the direction of the line, we push this strip into the holes in line so as to form slots of tape, we insert into the slots of the pads in order to form the support pads.

Selon, un premier mode de réalisation le matériau est souple (un tissu par exemple) et la bande est fixée sur la base à ses extrémités. Selon un second mode de réalisation, le matériau est rigide et pliable, c'est-à-dire qu'il est généralement rigide mais comporte des pliures préformées ou réalisées au moment même de l'enfoncement. Les créneaux peuvent être formés avant d'insérer les patins, ou au moment même ou on enfonce les patins. Les bandes sont avantageusement fixées à leur extrémités à la base.According to a first embodiment, the material is flexible (a fabric for example) and the strip is fixed to the base at its ends. According to a second embodiment, the material is rigid and pliable, that is to say that it is generally rigid but comprises folds that are preformed or made at the same time as being pressed. The slots can be formed before inserting the pads, or at the same time that the pads are pressed. The strips are advantageously fixed at their ends to the base.

Du fait que les bandes sont souples ou pliables, elles n'occupent, avant la formation des créneaux, qu'un faible volume. On peut facilement empiler des stocks de bases pourvus de trous et de bandes.Because the bands are flexible or foldable, they occupy, before the formation of slots, a small volume. You can easily stack base stocks with holes and bands.

Les patins sont avantageusement des blocs de polystyrène expansé, en raison de la résistance (à la compression notamment) de ce matériau, de son insensibilité à l'humidité, et de sa légèreté. Les bandes sont avantageusement en profilé creux à caissons parallèles, de deux ou trois millimètres d'épaisseur, en polypropylène, qui présente aussi des avantages de résistance (à la traction et à l'abrasion), d'insensibilité à l'humidité, et de légèreté.The pads are advantageously blocks of expanded polystyrene, because of the resistance (in particular to compression) of this material, its insensitivity to humidity, and its lightness. The bands are advantageously made of hollow profile with parallel boxes, two or three millimeters thick, made of polypropylene, which also has advantages of resistance (to traction and abrasion), insensitivity to humidity, and lightness.

Même en cas d'effort latéral sur les pieds, les bandes répartissent les efforts sur une large surface du carton formant la base, et les arrachements de pieds ne sont plus à craindre.Even in the event of lateral force on the feet, the bands distribute the forces over a large area of the cardboard forming the base, and the tearing of the feet is no longer to be feared.

Avantageusement, on prévoit une fixation supplémentaire des patins sur les bandes : ce peut être un point de colle, ou des organes d'accrochage annexes (tels que saillies du patin coopérant avec des encoches des créneaux de bandes, ou des languettes prises sur la bande). Bien que les patins soient autobloquants dans les trous de la base, cette fixation supplémentaire peut être utile si la palette doit être manipulée abondamment sans être chargée (la charge bloquant définitivement les patins).Advantageously, provision is made for an additional fixing of the pads on the strips: this may be a point of glue, or additional attachment members (such as protrusions of the pad cooperating with notches in the slots of strips, or tongues taken on the strip ). Although the pads are self-locking in the holes in the base, this additional attachment can be useful if the pallet must be handled abundantly without being loaded (the load permanently blocking the pads).

D'autres avantages et caractéristiques de l'invention ressortiront de la description suivante d'un mode préféré de réalisation. Il sera fait référence aux dessins annexés sur lesquels :

  • La figure 1 est une vue de dessus d'une palette conforme à l'invention.
  • La figure 2 est une coupe II-II de la figure 1.
Other advantages and characteristics of the invention will emerge from the following description of a preferred embodiment. Reference will be made to the appended drawings in which:
  • Figure 1 is a top view of a pallet according to the invention.
  • Figure 2 is a section II-II of Figure 1.

La palette comporte une base 1 faite d'un matériau rigide tel que du carton, du polypropylène, stratifié ou autre, dans lequel on a prévu, par découpage, matriçage ou autre procédé quelconque, un certain nombre de trous 2 destinés à la mise en place des plots de support. Leur nombre est fonction de la taille et de la charge de la palette.The pallet has a base 1 made of a rigid material such as cardboard, polypropylene, laminate or the like, in which a number of holes 2 are provided for cutting, stamping or any other method. place support pads. Their number depends on the size and load of the pallet.

Ces trous sont alignés au moins selon une direction, pour pouvoir disposer les bandes conformes à l'invention. Généralement les trous sont aussi alignés perpendiculairement à la première direction pour former les palettes à quatre entrées.These holes are aligned at least in one direction, to be able to arrange the strips according to the invention. Generally the holes are also aligned perpendicular to the first direction to form the four entry pallets.

On dispose au dessus des lignes de trous des bandes 3 de largeur inférieure ou égale à la largeur des trous 2 considérée dans le sens des lignes de trous. Ces bandes 3 sont en matériau susceptible de permettre un enfoncement de la bande dans les trous 2. Il peut s'agir d'un matériau souple (textile, plastique souple), ou d'un matériau relativement rigide dans lequel on réalise des pliures. A titre d'exemple, les bandes sont avantageusement constituées d'un profilé creux en polypropylène. Il est préférable que le matériau ne craigne pas l'humidité et soit résistant aux frottements puisqu'il formera l'extérieur des plots de support de la palette.There are above the lines of holes strips 3 of width less than or equal to the width of the holes 2 considered in the direction of the lines of holes. These strips 3 are made of material capable of allowing the strip to be pushed into the holes 2. It may be a flexible material (textile, flexible plastic), or a relatively rigid material in which folds are produced. By way of example, the strips advantageously consist of a hollow polypropylene profile. It is preferable that the material does not fear humidity and is resistant to friction since it will form the outside of the support pads of the pallet.

- Les bandes 3 sont fixées à la base 1 à leurs extrémités, par exemple par un simple agrafage 4.- The bands 3 are fixed to the base 1 at their ends, for example by simple stapling 4.

Pour installer les plots, les bandes 3 sont enfoncées dans les trous 2 de manière à former des créneaux dans lesquels sont insérés des patins 5. Ceux-ci sont réalisés par exemple sous forme de blocs de polystyrène expansé découpés à la forme des trous et à la hauteur désirée des plots. Les dimensions des patins 5 et des trous 2 sont très voisines de sorte que, compte-tenu de l'épaisseur des bandes 3, les patins 5 sont retenus en place par frottement. On peut, au lieu ou en plus de fixer les bandes 3 à la base 1 par agrafage, les y coller (en dehors des créneaux). Pour faciliter l'empilage des bases pourvues de bandes à créneaux mais sans blocs, on peut lorsque les bandes 3 sont en matière rigide, prévoir des pliures supplémentaires formant charnières juste au niveau de la face inférieure de la base 1. Les créneaux forment alors des parallélogrammes articulés facilement repliables.To install the studs, the strips 3 are driven into the holes 2 so as to form slots in which are inserted pads 5. These are produced for example in the form of blocks of expanded polystyrene cut to the shape of the holes and at the desired height of the studs. The dimensions of the pads 5 and the holes 2 are very similar so that, taking into account the thickness of the strips 3, the pads 5 are held in place by friction. It is possible, instead of or in addition to fixing the strips 3 to the base 1 by stapling, sticking them there (outside the slots). To facilitate stacking of the bases provided with strips with slots but without blocks, it is possible, when the strips 3 are made of rigid material, to provide additional folds forming hinges just at the level of the underside of the base 1. The slots then form easily foldable articulated parallelograms.

Quoique les patins soient empêchés de ressortir de la base, lors de l'utilisation de la palette, par la charge portée par la palette, on peut si on le souhaite assurer plus complètement leur maintien en place à vide par un point de colle à la face inférieure des patins, ou par des ergots prévus sur les faces latérales du patin, coopérant avec des encoches prévues dans les créneaux de bandes entourant les patins. Ces deux solutions permettent de bloquer les patins notamment dans le sens de la largeur des bandes 3. On peut aussi, comme représenté pour un seul des patins 5 sur les figures, découper dans les bandes 3 une languette 6, dont le rattachement se situe au niveau d'une pliure supérieure d'un créneau. Lors de l'enfoncement des créneaux et des patins, on écarte cette languette de façon qu'elle ne s'enfonce pas, mais reste au contraire au dessus du patin 5 qu' elle empêche de ressortir. On peut prévoir deux languettes par patin. Cette solution présente l'avantage d'offrir à la charge une surface de support à peu près uniforme. On peut également prévoir une base 1 en portefeuille, c'est-à-dire comportant un ou plusieurs rabats qui viennent couvrir la base après montage des patins.Although the pads are prevented from coming out of the base, when using the pallet, by the load carried by the pallet, it is possible, if desired, to more fully ensure that they are held in place empty by a point of glue at the underside of the pads, or by lugs provided on the side faces of the pad, cooperating with notches provided in the slots of bands surrounding the pads. These two solutions make it possible to block the pads in particular in the direction of the width of the bands 3. It is also possible, as shown for only one of the pads 5 in the figures, to cut in the bands 3 a tongue 6, the attachment of which is located at level of an upper fold of a niche. When slots and pads are pushed in, this tab is moved apart so that it does not sink, but on the contrary remains above the pad 5 which it prevents from coming out. We can provide two tabs per pad. This solution has the advantage of offering the load a roughly uniform support surface. It is also possible to provide a base 1 in the portfolio, that is to say comprising one or more flaps which cover the base after mounting the pads.

La forme des patins 5 n'est pas limitée à des blocs parallélépipédiques. De plus, au lieu d'être des blocs pleins, ils peuvent éventuellement être creux (à condition de résister à l'écrasement). Si la palette n'est qu'à deux entrées, on peut remplacer les patins séparés de lignes de patins voisines par des patins allongés, enserrés dans les créneaux de bandes voisines.The shape of the pads 5 is not limited to parallelepipedic blocks. In addition, instead of being solid blocks, they can possibly be hollow (provided they resist crushing). If the pallet is only at two entrances, one can replace the skids separated from neighboring skate lines by elongated skids, enclosed in the slots of neighboring bands.

Claims (5)

1. Method for preparing a pallet of the type comprising a base (1) provided with blocks, of the type whereby lines of holes (2) are formed in the base (1), characterized in that over a line of holes (2) is placed a strip (3) of supple material of width less than or equal to the width of the holes (2) in the direction of the line, said strip (3) is fixed on the base (1) at its ends, then said strip (3) is sunk into the holes (2) in a line in order to form crenels in the strip, and pads (5) are inserted in said crenels in order to form the supporting blocks.
2. Method for preparing a pallet of the type comprising a base (1) provided with blocks, of the type whereby lines of holes (2) are formed in the base (1), characterized in that over a line of holes (2) is placed a strip (3) of rigid and foldable material of width less than or equal to the width of the holes (2) in the direction of the line, said strip (3) being sunk in the holes (2) in a line so as to form crenels of strip, and pads (5) being inserted in the crenels to form the supporting blocks.
3. Method according to claim 2, characterized in that the strip (3) is fixed on the base (1) at its ends.
4. Method according to any one of claims 1 to 3, characterized in that additional means are provided for securing the pads (5) on the strips (3).
