Description

La présente invention concerne le domaine technique de l'organisation de produits divers sous forme de charges élémentaires pouvant être aisément stockées, transportées et manutentionnées.The present invention relates to the technical field of the organization of various products in the form of elementary loads which can be easily stored, transported and handled.

La présente invention vise, plus particulièrement, l'organisation de produits sous forme de paletées constituées par un empilement reposant sur une palette.The present invention relates, more particularly, to the organization of products in the form of pallets constituted by a stack resting on a pallet.

La présente invention vise, à titre d'application préférée, les produits qui sont constitués sous forme de lits superposés maintenus sur une palette de base, par l'intermédiaire d'une housse en matière plastique thermorétractable. A titre d'exemple, l'objet de l'invention vise, plus spécifiquement, les paletées de bouteilles ou articles analogues, qu'ils soient vides ou remplis.The present invention relates, by way of preferred application, to products which are constituted in the form of bunk beds held on a basic pallet, by means of a cover made of heat-shrinkable plastic material. By way of example, the subject of the invention relates, more specifically, to the pallets of bottles or similar articles, whether empty or filled.

La fig. 1 montre une paletée 1 constituée, de façon traditionnelle, à partir d'une base formée par une palette 2 représentant un polygone de sustentation, généralement rectangulaire. La palette 2 peut être constituée de plusieurs façons différentes et à base de matériaux variables mais comprend, généralement, un plancher 3 qui est monté sur des plots 4 reliés entre eux par des semelles 5. Fig. 1 shows a pallet 1 formed, in a traditional manner, from a base formed by a pallet 2 representing a support polygon, generally rectangular. The pallet 2 can be made up in several different ways and based on variable materials, but generally includes a floor 3 which is mounted on studs 4 connected together by soles 5 .

La paletée 1, constituée selon l'exemple illustré à partir de bouteilles 6, est formée, de façon habituelle, par la pose sur le plancher 3 d'un tapis de sol 7 à base de matière plastique thermorétractable, dont la surface est choisie supérieure à celle du plancher pour comporter une marge 8 excédentaire, périphérique. Le tapis de sol 7 est recouvert d'un bac ou plateau intercalaire 9 permettant l'établissement d'un premier lit 10a de bouteilles 6 qui sont rangées selon tous appareils appropriés. Un second lit 10b est formé, sur le premierlit 10a , par la pose d'un plateau intercalaire 9 permettant le rangement de bouteilles 6. Un nombre n de plateaux sont constitués ainsi par superposition, aprés quoi le dernier lit 10n est recouvert d'une coiffe 11 qui peut être constituée par un plateau intercalaire 9 retourné.The pallet 1 , formed according to the example illustrated from bottles 6 , is formed, in the usual way, by the laying on the floor 3 of a floor mat 7 based on heat-shrinkable plastic, the surface of which is chosen to be greater to that of the floor to include an excess margin 8 , peripheral. The floor mat 7 is covered with an intermediate tray or tray 9 allowing the establishment of a first bed 10 a of bottles 6 which are stored according to all appropriate devices. A second bed 10 b is formed, on the first bed 10 a , by the installation of an intermediate plate 9 allowing the storage of bottles 6 . A number n of trays are thus formed by superposition, after which the last bed 10 n is covered with a cap 11 which can be constituted by an inverted intermediate plate 9 .

La paletée est ensuite complétée par la pose d'une housse 12 en une matière plastique thermorétractable, comportant un dessus 13 et une jupe 14 entourant toute la charge constituée par les différents lits 10, de telle manière que sa base 15 recouvre la marge débordante 8 du tapis de sol 7. La paletée est ensuite soumise à une montée en température, de manière à provoquer, d'une part, la liaison entre la base 15 et la marge 8, par exemple par collage ou par soudure, puis, ensuite et/ou simultanément, la rétractation dans le plan vertical, mais aussi horizontal, afin d'enserrer étroitement la charge constituée et de l'arrimer sur le plancher 3 pour la stabiliser lors des opérations de stockage, de transport, voire de gerbage.The pallet is then completed by the installation of a cover 12 made of a heat-shrinkable plastic material, comprising a top 13 and a skirt 14 surrounding all the load formed by the various beds 10 , so that its base 15 covers the overhanging margin 8 floor mat 7 . The pallet is then subjected to a rise in temperature, so as to cause, on the one hand, the connection between the base 15 and the margin 8 , for example by gluing or by welding, then, then and / or simultaneously, the retraction in the vertical plane, but also in the horizontal plane, in order to tightly enclose the load formed and to stow it on the floor 3 to stabilize it during storage, transport, or even stacking operations.

Si la technique ci-dessus donne satisfaction pour la fonction de constitution d'une charge, en revanche, elle pose de sérieux problèmes lorsqu'il est nécessaire d'assurer, par l'intermédiaire d'une installation automatique, la dépalettisation des articles, tels que les bouteilles 6.If the above technique gives satisfaction for the function of constituting a load, on the other hand, it poses serious problems when it is necessary to ensure, by means of an automatic installation, the depalletization of the articles, such as bottles 6 .

Une telle opération consiste à détourer la housse 12, notamment au niveau de la liaison avec la marge périphérique 8, afin de permettre l'enlèvement de la housse donnant un accès à la coiffe 11 qui, après enlèvement, permet la préhension des articles, tels que les bouteilles 6.Such an operation consists in trimming the cover 12 , in particular at the level of the connection with the peripheral margin 8 , in order to allow the removal of the cover giving access to the cover 11 which, after removal, allows the gripping of articles, such than bottles 6 .

On conçoit qu'une telle opération peut s'effectuer de façon automatique pour toutes les opérations intermédiaires ci-dessus. En effet, de telles installations possèdent des moyens de détourage de la housse, d'enlèvement de cette dernière, de préhension de la coiffe 11, de prélèvement des articles 6, tels que les bouteilles, d'enlèvement de chaque plateau intercalaire 9.It is understood that such an operation can be carried out automatically for all of the above intermediate operations. Indeed, such installations have means for trimming the cover, for removing the latter, for gripping the cover 11 , for removing articles 6 , such as bottles, for removing each intermediate plate 9 .

L'opération de détourage de la housse 11 se traduit par un sectionnement, un déchirement, une rupture ou une coupe du tapis de sol 7 autour du périmètre du plancher 3.The clipping operation of the cover 11 results in cutting, tearing, breaking or cutting of the floor mat 7 around the perimeter of the floor 3 .

Lors de l'enlèvement automatique du plateau intercalaire de base 9, il se produit, alors, par effet de pompage, l'entraînement temporaire du tapis de sol 7 détouré qui, au moment du transfert, est soumis à flottement et à chute naturelle par gravité de façon imprévisible, le long du trajet du manipulateur emportant le dernier plateau intercalaire 9 hors de la ligne de dépalettisation.During the automatic removal of the base intermediate plate 9 , it then occurs, by pumping effect, the temporary drive of the clipped floor mat 7 which, at the time of transfer, is subject to floating and natural fall by gravity in an unpredictable manner, along the path of the manipulator carrying the last intermediate plate 9 out of the depalletization line.

La chute inopinée et incontrôlable du tapis de sol détouré 7 se traduit, de façon fréquente, par une mise hors service automatique de l'installation, dont les capteurs, détecteurs ou autres organes de sécurité ont perçu la présence intempestive et non prévue d'un corps étranger susceptible d'entraver le fonctionnement automatique de l'installation.The unexpected and uncontrollable fall of the clipped floor mat 7 frequently results in an automatic deactivation of the installation, the untimely and unforeseen presence of a sensor, sensors, detectors or other safety devices. foreign body likely to interfere with the automatic operation of the installation.

L'expérience de fonctionnement de telles installations permet de considérer qu'une mise hors service par sécurité peut intervenir pour chaque dépalettisation.The operating experience of such installations makes it possible to consider that a deactivation by safety can intervene for each depalletization.

On conçoit qu'un tel fonctionnement intempestif est incompatible avec la conduite d'une installation de dépalettisation automatique.It is understood that such untimely operation is incompatible with the operation of an automatic depalletization installation.

Il pourrait être considéré que la solution au problème ci-dessus consiste à lier ou à solidariser le tapis de sol 7, soit avec la palette 2, soit avec le premier plateau intercalaire 9.It could be considered that the solution to the above problem consists in tying or securing the floor mat 7 , either with the pallet 2 , or with the first intermediate plate 9 .

Si une telle proposition peut être appréciée comme apportant théoriquement une solution au problème posé, elle s'avère, en revanche, incompatible avec les normes de recyclage des palettes 3 ou des plateaux 9, que ces derniers soient ou non réutilisables. En effet, un principe de base, pour envisager un tel recyclage de façon économique, consiste à pouvoir disposer de produits homogénes qui peuvent être traités de la façon la plus simple et pratique possible. En ce sens, il est donc exclu que les palettes 2 ou les plateaux intercalaires 9 soient, pour partie, associés à un tapis de sol 7, dont la matière constitutive est différente et dont la liaison peut faire intervenir la présence d'un matériau encore différent.If such a proposition can be appreciated as theoretically providing a solution to the problem posed, it turns out, on the other hand, to be incompatible with the standards for recycling pallets 3 or trays 9 , whether or not the latter are reusable. Indeed, a basic principle, to envisage such recycling economically, consists in being able to have homogeneous products which can be treated in the simplest and practical way possible. In this sense, it is therefore excluded that the pallets 2 or the intermediate plates 9 are, in part, associated with a floor mat 7 , the constituent material of which is different and the connection of which may involve the presence of a material still different.

L'objet de l'invention consiste à proposer un nouveau procédé de stabilisation et d'arrimage d'une charge palettisée sur une palette, procédé permettant de supprimer totalement les dysfonctionnements intempestifs dûs à la présence et à la chute inopinées selon les techniques traditionnelles d'un tapis de sol en une matière plastique thermorétractable.The object of the invention is to propose a new method for stabilizing and securing a palletized load on a pallet, a method making it possible to completely eliminate the untimely malfunctions due to the unexpected presence and fall according to traditional techniques of a floor mat made of a heat-shrinkable plastic material.

Pour atteindre cet objectif, le procédé selon l'invention consiste à :

  • entourer la palette avec une bande de matiére thermorétractable,
  • immobiliser ladite bande par une ceinture cerclant ladite bande et se trouvant tendue autour de la palette et sous le plancher de cette dernière,
  • replier ensemble les demi-largeurs de la bande de part et d'autre de la ceinture et vers l'extérieur de la palette,
  • relever les demi-largeurs,
  • assembler la base de la jupe de la housse auxdites demi-largeurs relevées,
  • et soumettre la housse à thermorétraction.
To achieve this objective, the method according to the invention consists in:
  • surround the pallet with a strip of heat-shrinkable material,
  • immobilizing said strip by a belt encircling said strip and being stretched around the pallet and under the floor of the latter,
  • fold the half-widths of the strip together on both sides of the belt and towards the outside of the pallet,
  • note the half-widths,
  • assemble the base of the skirt of the cover to said raised half-widths,
  • and subject the cover to heat shrink.

La présente invention a également pour objet le produit nouveau constitué par une paletée formée en mettant en oeuvre les moyens de l'invention.The present invention also relates to the new product consisting of a pallet formed by using the means of the invention.

Diverses autres caractéristiques ressortent de la description faite ci-dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

La fig. 1 est une représentation schématique d'une paletée conforme à l'art antérieur. Fig. 1 is a schematic representation of a pallet according to the prior art.

Les fig. 2 à 4 sont des coupes partielles illustrant le procédé de l'invention. Figs. 2 to 4 are partial sections illustrating the process of the invention.

La fig. 5 est une coupe partielle montrant une variante de mise en oeuvre du procédé de l'invention. Fig. 5 is a partial section showing a variant implementation of the method of the invention.

Les fig. 2 à 4 illustrent une première mise en oeuvre du procédé de l'invention consistant à assurer la stabilisation et l'arrimage d'une charge sur une palette 2, du type habituel et constituée, comme dans l'art antérieur, par des semelles 5 reliant des plots 4 sur lesquels est adapté un plancher 3. La charge, telle qu'illustrée, est constituée par des bouteilles 6 qui sont établies en lits superposés 10, comme décrit précédemment. Figs. 2 to 4 illustrate a first implementation of the method of the invention consisting in ensuring the stabilization and securing of a load on a pallet 2 , of the usual type and constituted, as in the prior art, by soles 5 connecting studs 4 on which is fitted a floor 3 . The load, as illustrated, consists of bottles 6 which are established in bunk beds 10 , as described above.

Les fig. 2 et 3 illustrent des phases particulières de mise en oeuvre du procédé. Ces figures présentent la caractéristique de faire apparaître des épaisseurs de matériaux disproportionnés relativement. Il s'agit d'une volonté pour mieux faire apparaître les différents éléments constitutifs mis en oeuvre, étant entendu que l'homme de l'art possède par sa connaissance les moyens de rétablir les relations dimensionnelles et d'épaisseur qui interviennent dans la réalité. Figs. 2 and 3 illustrate particular phases of implementation of the method. These figures have the characteristic of showing thicknesses of materials that are relatively disproportionate. It is a desire to better show the different constituent elements used, it being understood that those skilled in the art have, by their knowledge, the means to restore the dimensional and thickness relationships which occur in reality .

La première phase du procédé de l'invention consiste à entourer la palette 2 avec une bande 20 qui est, de préférence, choisie en un matériau thermiquement compatible avec celui de la housse 12. La bande 20 peut être une bande au vrai sens du terme ou, encore, un anneau à même d'être enfilé sur la palette 2. Dans tous les cas, la bande 20 présente une hauteur supérieure à celle de la palette 2 pour des raisons qui apparaîssent dans ce qui suit.The first phase of the process of the invention consists in surrounding the pallet 2 with a strip 20 which is preferably chosen from a material thermally compatible with that of the cover 12 . The strip 20 can be a strip in the true sense of the term or, again, a ring capable of being threaded on the pallet 2 . In all cases, the strip 20 has a height greater than that of the pallet 2 for reasons which appear in the following.

La bande 20 est maintenue autour de la périphérie de la palette 2 par l'intermédiaire d'une ceinture 21 qui est tendue de manière à être disposée autour des plots 4 et sensiblement sous le plancher 3. La ceinture 21 est constituée par un cordon en un matériau également thermiquement compatible avec celui de la housse. Généralement, le matériau constitutif de la ceinture 21 et de la bande 20 est du polyéthylène.The strip 20 is held around the periphery of the pallet 2 by means of a belt 21 which is stretched so as to be arranged around the studs 4 and substantially under the floor 3 . The belt 21 consists of a cord made of a material also thermally compatible with that of the cover. Generally, the material constituting the belt 21 and the band 20 is polyethylene.

L'adaptation de la bande 20 et de la ceinture 21 peut être assurée, avant ou après constitution de la charge, par la mise en place des différents lits successifs 10.The adaptation of the band 20 and of the belt 21 can be ensured, before or after constitution of the load, by the installation of the different successive beds 10 .

La fig. 3 montre une seconde phase opératoire du procédé, selon laquelle la demi-largeur 20a de la bande 20, située sous la ceinture 21, est relevée en direction de la demi-largeur 20b , de telle façon que les deux demi-largeurs accollées soient, également, relevées autour du plancher 3. Le maintien dans une position stable peut être assuré par effet de thermorétractation locale, par exemple intervenant au droit des angles du plancher 3. Fig. 3 shows a second operational phase of the process, according to which the half-width 20 a of the strip 20 , located under the belt 21 , is raised in the direction of the half-width 20 b , in such a way that the two half-widths joined together are also raised around the floor 3 . Maintaining in a stable position can be ensured by local heat-shrinking effect, for example occurring at right angles to the floor 3 .

Une troisième phase opératoire, telle qu'illustrée par la fig. 4, consiste à enfiler la housse 12 sur la charge constituée, de telle façon que la jupe 14 entoure les différents lits 10 et que la base 15 de la jupe soit amenée à recouvrir périphériquement et extérieurement les bords 20a et 20b relevés. Dans cet état, la housse 12, ainsi que la bande 20, voire la ceinture 21, sont soumises à effet de thermorétractation, après qu'une liaison thermique a été établie entre la base 15 et les bords relevés 20a et 20b .A third operating phase, as illustrated in FIG. 4, is to insert the cover 12 of the incorporated filler, such that the skirt 14 surrounds the different beds 10 and the base 15 of the skirt is caused to cover peripherally and outwardly of the edges 20 a and 20 b readings. In this state, the cover 12 , as well as the band 20 , or even the belt 21 , are subjected to a heat-shrinking effect, after a thermal connection has been established between the base 15 and the raised edges 20 a and 20 b .

Selon les techniques mises en oeuvre, la liaison thermique peut intervenir avant ou simultanément à l'effet de rétractation, l'essentiel étant que la rétractation maximale proprement dite intervienne après liaison entre la base 15 et les parties repliée et relevée 20a et 20b .Depending on the techniques used, the thermal connection can take place before or simultaneously with the retraction effect, the main thing being that the maximum retraction proper occurs after connection between the base 15 and the folded and raised parts 20 a and 20 b .

De la sorte, la housse 12 est contrainte autour de la charge et autour du plancher 3, sous lequel la ceinture 21 sert, maintient et immobilise la bande 20 qui constitue un entourage de liaison physique pour la base 15 de la jupe 14 de la housse 12.In this way, the cover 12 is constrained around the load and around the floor 3 , under which the belt 21 serves, maintains and immobilizes the strip 20 which constitutes a physical connection frame for the base 15 of the skirt 14 of the cover 12 .

Par les moyens ci-dessus, il est établi une stabilisation de la charge, ainsi qu'un arrimage de cette dernière sur le plancher de la palette, en vue de permettre et faciliter une manutention, un transport, un stockage, voire un gerbage de la paletée obtenue.By the above means, it is established a stabilization of the load, as well as a stowage of the latter on the floor of the pallet, in order to allow and facilitate handling, transport, storage, or even stacking of the paletée obtained.

Lorsqu'il convient de procéder à l'ouverture de la paletée, par exemple dans une installation de dépalettisation automatique, en vue de rendre accessibles les bouteilles 6, ainsi que leur préhension pour une utilisation ultérieure, il suffit de fendre verticalement au moins la jupe 14 jusque et y compris la base 15, la bande 20 et la ceinture 21, pour ouvrir complètement la housse qui, dans son ensemble et dans son intégrité, peut être enlevée de la paletée pour découvrir totalement l'ensemble des lits 10 superposés.When it is appropriate to open the pallet, for example in an automatic depalletizing installation, in order to make the bottles 6 accessible, as well as their grip for later use, it suffices to split vertically at least the skirt 14 up to and including the base 15 , the band 20 and the belt 21 , to completely open the cover which, as a whole and in its integrity, can be removed from the pallet to fully discover all of the bunk beds 10 .

La dépalettisation peut alors intervenir par étages successifs, jusqu'à l'enlèvement du dernier plateau intercalaire 9, sans aucun risque d'interruption du fonctionnement automatique, en raison de l'absence d'un tapis de sol, comme dans l'art antérieur.Depalletization can then take place in successive stages, until the last intermediate plate 9 is removed, without any risk of interruption of automatic operation, in because of the absence of a floor mat, as in the prior art.

La fig. 5 montre une variante de réalisation consistant à former la bande 20 autour de la palette 2 avant constitution de la charge, de manière à pouvoir replier les demi-largeurs 20a et 20b relevées par dessus le plancher 3, avant la pose du premier plateau intercalaire 9. Le maintien de la bande, dans la position illustrée par la fig. 5, peut intervenir facilement par action de thermorétractation locale et permet d'envisager la préparation des différentes palettes en amont d'une installation de constitution en continu de charges palettisées. Fig. 5 shows an alternative embodiment consisting in forming the strip 20 around the pallet 2 before the load is built up, so as to be able to fold the half-widths 20 a and 20 b raised over the floor 3 , before laying the first tray tab 9 . Maintaining the strip in the position illustrated in FIG. 5 , can easily intervene by local heat-shrinking action and makes it possible to envisage the preparation of the different pallets upstream of an installation for continuously building up palletized loads.

Les mêmes avantages que ci-dessus découlent de cette variante, car l'ouverture intégrale et complète de la housse peut intervenir dans les mêmes conditions, étant donné que les parties repliées 20a , 20b ne sont insérées que périphériquement et sur une faible largeur sous le premier plateau 9 et permettent une extraction rapide de la ceinture de liaison après fente de la jupe 14, lors de l'enlèvement de la housse 12.The same advantages as above result from this variant, because the complete and complete opening of the cover can occur under the same conditions, since the folded parts 20 a , 20 b are inserted only peripherally and over a narrow width under the first plate 9 and allow rapid extraction of the connecting belt after the skirt 14 has been slit, when the cover 12 is removed.

L'invention n'est pas limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown, since various modifications can be made thereto without departing from its scope.
