Description

L'invention concerne un procédé perfectionné de conditionnement d'une charge palettisable, et notamment un procédé de chargement automatique et de banderolage d'une charge sur une palette. L'invention concerne également l'installation permettant la mise en oeuvre de ce procédé.The invention relates to an improved method of packaging a palletizable load, and in particular an automatic loading and wrapping process of a load on a pallet. The invention also relates to the installation allowing the implementation of this method.

Depuis bien longtemps déjà, le transport de matières tant en vrac que sous forme de conditionnements primaires, tels que paquets, bouteilles, etc..., s'effectue au moyen de palettes sur lesquelles les conditionnements primaires sont maintenus par .des moyens de fixation comme des housses thermorétractables ou par enveloppement à l'aide d'une bande, cette dernière technique étant connue sous le nom de "banderolage". De fait, et de plus en plus, on cherche à minimiser la durée nécessaire au chargement de ces palettes et à leur banderolage, -lorsque cette technique est mise en oeuvre-, tout en augmentant leurs capacités de résistance aux différents chocs qu'elles sont susceptibles de subir lors du transport et des différentes manutentions dont elles font l'objet.For a long time now, the transport of materials both in bulk and in the form of primary packaging, such as packages, bottles, etc., has been carried out by means of pallets on which the primary packaging is held by fixing means. such as heat-shrinkable covers or by wrapping with a strip, the latter technique being known by the name of "wrapping". In fact, and more and more, we are trying to minimize the time necessary for loading these pallets and wrapping them, -when this technique is implemented, while increasing their resistance to the various shocks they are likely to undergo during transport and the various handling operations to which they are subject.

S'agissant de minimiser les durées de chargement, on connaît déjà des robots de palettisation qui, à partir d'un convoyeur, positionnent automatiquement les produits à charger, en conservant en mémoire les différentes positions susceptibles d'être comblées sur la palette, et le niveau de chargement en cours.As regards minimizing loading times, palletizing robots are already known which, from a conveyor, automatically position the products to be loaded, keeping in memory the different positions that can be filled on the pallet, and the level of loading in progress.

En outre, afin d'assurer une plus grande cohésion aux charges ainsi palettisées, il est connu, notamment avec des sacs de matières en vrac par exemple, d'enduire partiellement ces sacs au :moyen d'une colle dite "de palettisation", dont la propriété est de ne pas sécher complètement, permettant de coller ainsi entre eux les produits des niveaux intermédiaires. Néanmoins, cette mise en place de colle ne se révèle pas satisfaisante, compte-tenu qu'il s'avère généralement difficile de s'en débarasser totalement, et que de ce fait, elle est génératrice de saleté.In addition, in order to ensure greater cohesion to the loads thus palletized, it is known, in particular with bags of bulk materials for example, to partially coat these bags with: using a glue known as "palletizing", whose property is not dry completely, allowing products of intermediate levels to be bonded together. However, this placement of glue does not prove satisfactory, given that it is generally difficult to get rid of it completely, and that because of this, it generates dirt.

On a alors proposé d'intercaler entre les différents niveaux de palettisation des feuilles intermédiaires en carton ou en plastique. Si ces feuilles assurent la cohésion générale de la charge des produits d'une même couche ou d'un même niveau de palettisation, elles n'empêchent pas, en revanche, le glissement d'une couche complète par rapport à la couche précédente ou suivante et ce n'est qu'après mise en place du film plastique étirable de banderolage ou de la gaine thermorétractable qu'est obtenue la cohésion de l'ensemble des conditionnements primaires sur la palette.It was then proposed to interpose between the different levels of palletization of the intermediate sheets of cardboard or plastic. If these sheets ensure the general cohesion of the load of the products of the same layer or the same level of palletization, they do not prevent, on the other hand, the sliding of a complete layer compared to the previous or next layer. and it is only after putting in place the stretchable plastic wrapping film or the heat-shrinkable sheath that the cohesion of all of the primary packages on the pallet is obtained.

Bien que satisfaisantes sur le plan technique et sur le plan de l'automatisation, ces solutions présentent l'inconvénient rédhibitoire d'utiliser des films plastiques non dégradables naturellement, et à ce titre générateurs de pollution.Although satisfactory from the technical point of view and from the automation point of view, these solutions have the crippling drawback of using plastic films which are not naturally degradable, and as such generate pollution.

C'est, par conséquent, un but de l'invention de proposer un procédé de conditionnement d'une charge palettisable qui permette de s'affranchir des inconvénients inhérents aux films plastiques mis en oeuvre dans les techniques connues, d'une part, tout en assurant une excellente cohésion des charges palettisées, d'autre part.It is therefore an object of the invention to propose a method of packaging a palletizable load which overcomes the drawbacks inherent in plastic films used in known techniques, on the one hand, while by ensuring excellent cohesion of the palletized loads, on the other hand.

Le procédé pour conditionner une charge palettisable, dans lequel les éléments constitutifs de la charge sont positionnés sur la palette selon plusieurs niveaux ou couches de palettisation au moyen d'un robot dit "de palettisation" est caractérisé selon l'invention:The method for conditioning a palletizable load, in which the constituent elements of the load are positioned on the pallet according to several levels or layers of palletization by means of a robot called "palletization" is characterized according to the invention:

- en ce qu'entre chaque niveau de palettisation, on intercale une feuille d'un matériau présentant des propriétés anti-glisse ; et- in that between each level of palletization, a sheet of a material having anti-slip properties is inserted; and

- en ce que le banderolage périphérique de la charge s'effectue au moyen d'une bande de papier étirable.- in that the peripheral wrapping of the load is carried out by means of a strip of stretch paper.

En d'autres termes, l'invention consiste à augmenter la cohésion des charges palettisées en intercalant une feuille de matériau, susceptible de maintenir la cohésion d'une part entre les différents éléments d'un même niveau de palettisation, et d'autre part entre deux niveaux de palettisation consécutifs, tout en substituant au film plastique étirable ou thermorétractable de la technique connue une bande de papier étirable, notamment dans le sens de sa longueur, s'affranchissant ainsi de tous les inconvénients rédhibitoires liés aux films plastiques.In other words, the invention consists in increasing the cohesion of the palletized loads by interposing a sheet of material, capable of maintaining cohesion on the one hand between the different elements of the same level of palletization, and on the other hand between two consecutive palletization levels, while substituting for the stretchable or heat-shrinkable plastic film of the known technique a strip of stretchable paper, in particular in the direction of its length, thus eliminating all the prohibitive drawbacks linked to plastic films.

Dans certains cas, il est possible de n'utiliser-, en tant que feuille intermédiaire entre deux niveaux de palettisation-, qu'une bande d'un matériau anti-glisse, ne couvrant pas toute la largeur de la palette. Dans d'autres applications, le matériau antiglisse mis en oeuvre entre deux niveaux de palettisation est sous forme de deux bandes, parallèles ou croisées, ou une multitude de bandes sans nécessairement appliquer une couverture totale de la surface de la palette.In some cases, it is possible to use - as an intermediate sheet between two palletizing levels - only a strip of anti-slip material, not covering the entire width of the pallet. In other applications, the anti-slip material used between two palletization levels is in the form of two strips, parallel or crossed, or a multitude of strips without necessarily applying total coverage of the surface of the pallet.

L'invention concerne également une installation pour la mise en oeuvre du procédé tel qu'il vient d'être défini. Cette installation, comportant un dispositif de palettisation, destiné à positionner sur une palette les éléments constitutifs de la charge à partir d'un convoyeur et un dispositif de délivrance, de guidage et de positionnement d'une bande de papier étirable sur ladite charge pour le banderolage de la charge sur toute sa hauteur est caractérisée en ce qu'elle comprend en outre :

  • un portique, susceptible de dérouler au moins une bande d'un matériau anti-glisse au-dessus de chacun des niveaux de palettisation et de découper une longueur déterminée dudit matériau ; ainsi que des
  • moyens d'application de la bande de papier sur la charge après encollage de ladite bande de papier étiré, laquelle est coupée en fin de banderolage.
The invention also relates to an installation for implementing the method as just defined. This installation, comprising a palletizing device, intended to position on a pallet the constituent elements of the load from a conveyor and a device for delivering, guiding and positioning a strip of stretch paper on said load for the wrapping the load over its entire height is characterized in that it further comprises:
  • a gantry, capable of unwinding at least one strip of an anti-slip material above each of the palletizing levels and of cutting a determined length of said material; as well as
  • means for applying the strip of paper to the load after gluing said strip of stretched paper, which is cut at the end of wrapping.

Selon une forme avantageuse de l'invention, la bande de papier étirable est une bande de papier microcrêpé, laquelle est encollée par un organe solidaire du dispositif de délivrance, de guidage et de positionnement de la bande de papier.According to an advantageous form of the invention, the strip of stretch paper is a strip of micro-creped paper, which is glued by a member secured to the device for delivering, guiding and positioning the strip of paper.

Le dépôt d'adhésif par l'organe d'encollage peut n'être effectué que sur la partie de la bande de papier destinée à être immédiatement recouverte par le tour de bande suivant.The deposition of adhesive by the sizing member can only be carried out on the part of the paper strip intended to be immediately covered by the next turn of the strip.

Dans certains cas, on peut prévoir des moyens d'étirage, destinés à étirer la bande de papier microcrêpé selon une valeur prédéterminable, lesdits moyens étant situés en amont de l'organe de délivrance, de guidage et de positionnement de la bande de papier.In certain cases, it is possible to provide stretching means, intended to stretch the strip of micro-creped paper according to a predetermined value, said means being located upstream of the member for delivering, guiding and positioning the strip of paper.

De manière avantageuse, lesdits moyens d'étirage sont constitués par un jeu de rouleaux autour desquels est renvoyée la bande de papier microcrêpé, lesdits rouleaux tournant selon des vitesses tangentielles différentes.Advantageously, said drawing means consist of a set of rollers around which the strip of micro-creped paper is returned, said rollers rotating at different tangential speeds.

L'adhésif est une colle déposée sur la surface externe de la bande de papier, préalablement à son positionnement sur la charge palettisée.The adhesive is an adhesive deposited on the external surface of the paper strip, prior to its positioning on the palletized load.

Selon une forme de réalisation de l'invention, l'installation est du type à plateau horizontal rotatif propre à recevoir la palette et la charge, tandis que le dispositif de délivrance, de guidage et de positionnement de la bande de papier étirable est monté à translation sensiblement perpendiculairement audit plateau, ce dernier étant muni d'une pince de reprise de la bande de papier, destinée à saisir ladite bande lorsqu'elle a été coupée en fin de banderolage de la palette précédente, et afin de permettre la mise en place de ladite bande sur la palette suivante, ladite pince étant solidaire du plateau rotatif et étant escamotable sous le plan défini par ce dernier.According to one embodiment of the invention, the installation is of the type with a rotary horizontal plate suitable for receiving the pallet and the load, while the delivery, guiding and positioning device of the stretch paper strip is mounted in translation substantially perpendicular to said plate, the latter being provided with a gripper for taking up the paper strip, intended to grip said strip when it has been cut at the end of wrapping of the preceding pallet , and in order to allow the positioning of said strip on the following pallet, said clamp being integral with the rotary plate and being retractable under the plane defined by the latter.

Le portique destiné à permettre la mise en place du matériau anti-glisse, -et qui est avantageusement également du papier-, comporte deux bras horizontaux en porte-à-faux, au niveau desquels sont associés deux rouleaux, l'un moteur et l'autre presseur, destinés à faire défiler la bande de matériau antiglisse, simultanément à la progression des deux bras au niveau du portique.The gantry intended to allow the establishment of the anti-slip material, -and which is advantageously also paper-, has two horizontal cantilever arms, at the level of which are associated two rollers, one motor and the Another presser, intended to scroll the strip of non-slip material, simultaneously with the progression of the two arms at the level of the gantry.

Il va être décrit de manière détaillée une installation pour la mise en oeuvre du procédé conforme à l'invention. Cette installation pour conditionner une charge palettisable comprend un poste de travail, au niveau duquel est acheminée une palette rigide. Ce poste comporte un plateau horizontal 1, circulaire et rotatif par rapport à son axe central, la rotation de ce plateau étant assurée au moyen d'un moteur, non représenté, typiquement à une vitesse voisine de quinze tours/minute. Ce plateau 1 comporte sur une bonne partie de sa surface supérieure, des rouleaux rotatifs parallèles 3 destinés à permettre le positionnement sur le plateau de la palette à partir d'une voie d'accès 2 (comme un transporteur à rouleaux rotatifs 3′), d'une part et, d'autre part, l'évacuation de la palette chargée au poste suivant, non représenté, typiquement au poste d'embarquement et d'expédition de la palette ainsi chargée.There will be described in detail an installation for implementing the method according to the invention. This installation for packaging a palletizable load comprises a work station, at the level of which a rigid pallet is routed. This station comprises a horizontal plate 1, circular and rotary relative to its central axis, the rotation of this plate being ensured by means of a motor, not shown, typically at a speed close to fifteen revolutions / minute. This plate 1 comprises on a good part of its upper surface, parallel rotary rollers 3 intended to allow positioning on the plate of the pallet from an access path 2 (such as a conveyor with rotary rollers 3 ′), on the one hand and, on the other hand, the evacuation of the pallet loaded at the next station, not shown, typically at the boarding and shipping station of the pallet thus loaded.

Ce poste de travail comporte un poste de palettisation avantageusement automatique, mais qui dans certaines formes de réalisation de l'invention, pourrait être manuel. Attendu qu'il est connu d'utiliser des robots dits "de palettisation", qui positionnent et conservent en mémoire la position des éléments constitutifs d'une charge au niveau de chacun des niveaux de palettisation, à partir d'un convoyeur acheminant lesdits éléments, il n'y a pas lieu de décrire ici plus en détail un tel robot.This work station includes an advantageously automatic palletizing station, but which in certain embodiments of the invention, could be manual. Whereas it is known to use so-called "palletizing" robots, which position and store in memory the position of the components of a load at each of the palletization levels, from a conveyor conveying said elements , there is no need to describe here in more detail such a robot.

Selon l'invention, l'installation comporte en outre un portique, portant la référence générale 5, disposé au voisinage du plateau 1 et qui porte deux bras horizontaux, montés en porte-à-faux respectivement 6 et 7. Entre ces deux bras, est montée folle en rotation une bobine 8 d'un matériau 9 présentant des propriétés antiglisse sur l'une de ses faces, ou avantageusement sur ses deux faces, et qui est avantageusement du papier. Comme il sera décrit plus en détail ultérieurement, ce papier anti-glisse est destiné à conférer à l'ensemble de la charge palettisée une plus grande cohésion et corrélativement une plus grande résistance aux différents chocs auxquels elle peut être soumise, notamment lors de son transport.According to the invention, the installation further comprises a gantry, bearing the general reference 5, disposed in the vicinity of the plate 1 and which carries two horizontal arms, mounted in cantilever respectively 6 and 7. Between these two arms, is mounted madly in rotation a coil 8 of a material 9 having anti-slip properties on one of its faces, or advantageously on its two faces, and which is advantageously paper. As it will be described in more detail later, this anti-slip paper is intended to give the whole of the palletized load greater cohesion and correspondingly greater resistance to the various shocks to which it may be subjected, in particular during its transport.

Sont également montés entre les deux bras 6 et 7 du portique 5, deux rouleaux respectivement 10 et 11, l'un moteur et l'autre presseur, les deux rouleaux étant parallèles à la bobine 8 et en contact l'un de l'autre.Are also mounted between the two arms 6 and 7 of the gantry 5, two rollers respectively 10 and 11, one motor and the other presser, the two rollers being parallel to the coil 8 and in contact with each other .

Les deux bras 6 et 7 du portique 5 sont susceptibles de se déplacer simultanément verticalement d'une part, et horizontalement d'autre part. Le fonctionnement du portique sera également décrit plus en détail ultérieurement.The two arms 6 and 7 of the gantry 5 are capable of moving simultaneously vertically on the one hand, and horizontally on the other hand. The operation of the gantry will also be described in more detail later.

Selon une autre caractéristique de l'invention, l'installation comporte un poste ou dispositif délivreur d'une bande de papier étirable, et notamment d'un papier microcrêpé. Ce poste, également situé au voisinage du plateau central rotatif 1, comprend une bobine horizontale 12 dudit papier microcrêpé, dont le diamètre peut facilement atteindre et même dépasser le mètre, permettant ainsi une plus grande autonomie de l'installation automatique conforme à l'invention.According to another characteristic of the invention, the installation comprises a station or device for delivering a strip of stretch paper, and in particular micro-creped paper. This station, also located in the vicinity of the central rotating plate 1, comprises a horizontal spool 12 of said micro-creped paper, the diameter of which can easily reach and even exceed one meter, thus allowing greater autonomy of the automatic installation according to the invention .

Compte-tenu du poids relativement important de cette bobine, le rouleau 13 sur lequel est monté la bobine est motorisé, afin d'assurer une délivrance uniforme de la bande de papier. Cette bande de papier 14 est tout d'abord reprise par un jeu de rouleaux dévideurs (non représentés), puis est renvoyée au moyen d'un rouleau incliné (également non représenté) vers un plan vertical au niveau des moyens d'étirement du papier 15, lesdits moyens étant typiquement constitués d'une pluralité de rouleaux rotatifs verticaux, dont la vitesse tangentielle est différente, afin d'induire entre eux un étirement du papier crêpé ou microcrêpé d'une valeur comprise entre 50 et 100 % voire plus de sa longueur initiale.Given the relatively large weight of this spool, the roller 13 on which the spool is mounted is motorized, in order to ensure uniform delivery of the paper strip. This strip of paper 14 is first taken up by a set of unwinding rollers (not shown), then is returned by means of an inclined roller (also not shown) to a vertical plane at the level of the paper stretching means. 15, said means typically consisting of a plurality of vertical rotating rollers, the tangential speed of which is different, in order to induce between them a stretching of crepe or micro-crepe paper between 50 and 100% or more of its original length.

Il est à noter que les moyens d'étirement 15 ne sont pas nécessairement présents dans la mesure où l'étirement de la bande de papier 14 peut s'effectuer dans une installation selon l'invention sous la simple rotation de la charge 20, qui compte-tenu du freinage subi par la bande, inhérent à l'inertie des différents rouleaux de renvoi, entraîne l'allongement de la bande 14 et même son adaptation locale aux aspérités éventuelles de la charge.It should be noted that the stretching means 15 are not necessarily present insofar as the stretching of the paper strip 14 can be carried out in an installation according to the invention under the simple rotation of the load 20, which taking into account the braking undergone by the strip, inherent in the inertia of the various deflection rollers, leads to the elongation of the strip 14 and even its local adaptation to the possible roughness of the load.

De par l'utilisation de papier crêpé, on obtient un étirage local qui s'adapte étroitement au périmètre de la charge 20 à banderoler.Through the use of crepe paper, a local stretching is obtained which adapts closely to the perimeter of the load 20 to be wrapped.

La bande 14, ayant subi ou non un pré-étirage par les moyens 15, est prise en charge par un dispositif délivreur symbolisé par un rouleau 16, susceptible de se mouvoir selon une translation verticale, et ce par tout moyen approprié, notamment par un vérin, afin d'assurer le banderolage périphérique de la charge palettisée sur toute sa hauteur.The strip 14, which may or may not have been pre-stretched by the means 15, is supported by a delivery device symbolized by a roller 16, capable of moving in vertical translation, and this by any appropriate means, in particular by a cylinder, to ensure the peripheral wrapping of the palletized load over its entire height.

Selon l'invention, le dispositif délivreur 16 est avantageusement associé à un organe d'encollage 17, typiquement constitué par un pistolet et qui se déplace verticalement en translation avec le délivreur 16 afin de réaliser des points de colle 4 sur la face externe de la bande 14 à positionner sur la charge 20.According to the invention, the delivery device 16 is advantageously associated with a sizing member 17, typically constituted by a gun and which moves vertically in translation with the delivery device 16 in order to produce glue dots 4 on the external face of the strip 14 to be positioned on the load 20.

Selon une forme avantageuse de l'invention, cet organe 17 ne délivre de points de colle qu'en partie supérieure de ladite bande 14, lorsque le délivreur 16 est en phase ascensionnelle, et qu'en partie inférieure de cette même face externe lorsque le délivreur 16 est en phase de descente. Pour ce faire, l'organe d'encollage 17 peut avantageusement se mouvoir sur une tige-guide 24 solidaire du délivreur 16, et ce par exemple sous l'action d'un vérin (non représenté), également solidaire dudit délivreur. Ledit vérin provoque la mise en place de l'organe d'encollage 17 en partie supérieure de la course de la tige-guide 24 lors de la phase ascensionnelle de banderolage, et en partie inférieure de cette même course en phase de descente, comme on l'a par ailleur représenté sur les figures 5 à 8. De la sorte, la bande en cours d'apposition ne recouvre que la partie encollée de la bande précédente, et en outre, aucun point de colle ne reste découvert, ceci afin de diminuer voire d'annuler tout risque de collage intempestif, mais également de réduire la saleté générée par la colle. On observe ainsi la superposition d'une bande sur la suivante créant ainsi des zones de chevauchement, au niveau desquelles les points de colle 4 sont mis en place.According to an advantageous form of the invention, this member 17 only delivers glue points in the upper part of said strip 14, when the deliverer 16 is in the ascending phase, and in the lower part of this same external face when the deliverer 16 is in the descent phase. To do this, the sizing member 17 can advantageously move on a guide rod 24 secured to the deliverer 16, for example under the action of a jack (not shown), also secured to the said deliverer. Said cylinder causes the gluing member 17 to be positioned in the upper part of the travel of the guide rod 24 during the upward wrapping phase, and in the lower part of this same travel in the descent phase, as it is also shown in FIGS. 5 to 8. In this way, the strip being affixed covers only the glued part of the preceding strip, and in addition, no point of glue remains uncovered, this in order to reduce or even eliminate any risk of inadvertent sticking, but also reduce the dirt generated by the adhesive. One thus observes the superposition of one strip on the next, thus creating overlapping zones, at the level of which the glue dots 4 are put in place.

Ainsi, en cas de rupture intempestive brutale de la bande, notamment en région supérieure, le reste du banderolage est maintenu en place au niveau de la charge palettisée.Thus, in the event of sudden untimely rupture of the strip, in particular in the upper region, the rest of the wrapping is kept in place at the level of the palletized load.

Selon une autre caractéristique de l'invention, l'installation comporte également un ensemble de fixation et de positionnement de la bande de papier étirée, constitué par un bloc 18 mobile en translation horizontale, et destiné à venir se rapprocher de la charge 20, notamment en fin de banderolage. Ce bloc 18 comprend essentiellement un patin caoutchouté 19, lui-même actionné par un piston 22, et destiné à plaquer la bande de papier 14 en fin de banderolage sur la charge lorsque la découpe du papier est effectuée. Cette découpe est assurée au moyen d'une lame intégrée dans un guide 23 qui, en fin de banderolage, procède à la découpe de la bande en cours d'application, l'extrémité alors libre de la bande issue du délivreur 16 étant simultanément reprise par une pince (non représentée), comme il sera décrit ultérieurement lors de l'explication du fonctionnement de cette installation.According to another characteristic of the invention, the installation also includes a set for fixing and positioning the stretched paper strip, constituted by a block 18 movable in horizontal translation, and intended to come closer to the load 20, in particular at the end of wrapping. This block 18 essentially comprises a rubberized pad 19, itself actuated by a piston 22, and intended to press the strip of paper 14 at the end of wrapping on the load when the cutting of the paper is carried out. This cutting is carried out by means of a blade integrated in a guide 23 which, at the end of wrapping, cuts the strip during application, the free end of the strip then coming from the dispenser 16 being simultaneously resumed by pliers (not shown), as will be described later during the explanation of the operation of this installation.

Lorsqu'une palette vide arrive sur le plateau circulaire 1 par la voie d'accès 2, on procède par voie manuelle ou automatique au rangement des éléments 21 constitutifs de la charge 20 à palettiser selon un premier niveau de palettisation.When an empty pallet arrives on the circular tray 1 via the access path 2, the elements 21 constituting the load 20 to be palletized are stored manually or automatically according to a first level of palletization.

Une fois ce niveau complet, le portique 5 est rendu opératoire et plus précisément, les bras 6 et 7 viennent se positionner à hauteur légèrement supérieure dudit premier niveau de palettisation, puis lesdits bras se translatent horizontalement, jusqu'à ce que la bobine 8 vienne en limite externe dudit premier niveau.Once this level is complete, the gantry 5 is made operational and, more precisely, the arms 6 and 7 are positioned slightly higher than said first level of palletization, then said arms translate horizontally, until the coil 8 comes at the outer limit of said first level.

Lesdits bras 6, 7, reviennent alors à leur position horizontale d'origine, c'est-à-dire escamotés par rapport à ladite charge, et simultanément, le rouleau moteur 10 est activé afin de dérouler une bande 9 d'un papier anti-glisse sur toute ou partie de la surface dudit niveau de palettisation.Said arms 6, 7 then return to their original horizontal position, that is to say retracted with respect to said load, and simultaneously, the drive roller 10 is activated in order to unwind a strip 9 of anti-paper -slides over all or part of the surface of said level of palletization.

En effet, selon l'invention et en fonction de la densité ou du poids des éléments constitutifs des charges palettisées, on peut concevoir de positionner sur chacun des niveaux une feuille recouvrant la totalité de la surface dudit niveau, ou encore une bande mise en place dans le sens longueur ou largeur du niveau sans en couvrir la surface totale, voire en diagonale ou encore deux bandes dans le sens longueur, largeur ou en diagonale et éventuellement des bandes croisées. De la sorte, on peut ainsi économiser du papier anti-glisse.In fact, according to the invention and depending on the density or the weight of the elements making up the palletized loads, it is conceivable to position on each of the levels a sheet covering the entire surface of said level, or else a strip put in place. in the length or width direction of the level without covering the entire surface, or even diagonally or even two strips in the length, width or diagonal direction and possibly crossed bands. In this way, we can save anti-slip paper.

De fait et en fonction du choix de l'utilisateur, le portique 5 est activé un certain nombre de fois pour un même niveau, l'orientation de ladite bande sur ledit niveau de palettisation étant obtenue en procédant à une simple rotation du plateau circulaire 1.In fact and depending on the choice of the user, the gantry 5 is activated a certain number of times for the same level, the orientation of said strip on said palletization level being obtained by simply rotating the circular plate 1 .

Cette opération est répétée plusieurs fois, suivant le nombre de niveaux, jusqu'à ce que la charge totale 20 soit terminée. On procède alors au banderolage proprement dit de la charge ainsi palettisée.This operation is repeated several times, depending on the number of levels, until the total charge 20 is completed. The actual wrapping of the load thus palletized is then carried out.

On a représenté dans les figures 5 à 8 les différentes phases du banderolage au moyen de l'installation conforme à l'invention.Figures 5 to 8 show the different phases of wrapping by means of the installation according to the invention.

Lors des premières rotations, la bande 14 est reprise au moyen d'une pince non représentée, solidaire du plateau rotatif et escamotable en dessous du plan de ce dernier.During the first rotations, the strip 14 is taken up by means of a clamp, not shown, secured to the rotary plate and retractable below the plane of the latter.

Une fois le premier ou les premiers tours effectués, cette pince s'escamote, lesdites bandes étant maintenues par la simple traction.Once the first or first turns have been made, this clamp retracts, the said strips being held by simple traction.

Corrélativement, l'organe délivreur 16 subit une phase ascensionnelle (figure 6), tout en induisant un chevauchement d'une bande sur l'autre, et un pré-encollage de la surface extérieure de la bande précédente en zone supérieure, afin de n'encoller que le strict nécessaire de ladite bande.Correlatively, the delivery member 16 undergoes an ascending phase (FIG. 6), while inducing an overlap of one strip on the other, and a pre-gluing of the external surface of the preceding strip in the upper zone, in order to n '' glue only the bare necessities of said strip.

Une fois la phase ascensionnelle terminée, la phase de descente s'effectue de la même manière, ladite bande subissant toujours un pré-encollage. En fin de banderolage, la pince déjà mentionnée vient saisir la bande, et corrélativement, l'ensemble de la fixation et de positionnement 18 vient plaquer la dernière bande et découpe celle-ci au droit de la pince.Once the ascending phase is completed, the descent phase is carried out in the same manner, said strip always undergoing a pre-sizing. At the end of the wrapping, the clamp already mentioned comes to grip the strip, and correspondingly, the whole of the fixing and positioning 18 presses the last strip and cuts the latter to the right of the clamp.

La bande ainsi découpée est appliquée par le patin caoutchouté 19 contre la charge, l'extrémité libre de l'autre bande étant reprise par la pince et prête à banderoler une autre charge.The strip thus cut is applied by the rubberized pad 19 against the load, the free end of the other strip being taken up by the clamp and ready to bandage another load.

La charge ainsi banderolée peut être évacuée vers le lieu d'embarquement.The wrapped load can be removed to the place of embarkation.

Cette installation présente de nombreux avantages compte-tenu d'une part, de l'utilisation de papier naturellement dégradable pour le banderolage, et d'autre part, de l'introduction de papier anti-glisse conférant auxdites charges ainsi palettisées et conditionnées une cohésion que les moyens connus ce jour ne permettaient pas d'obtenir.This installation has many advantages taking into account on the one hand, the use of naturally degradable paper for wrapping, and on the other hand, the introduction of anti-slip paper giving said loads thus palletized and packaged a cohesion that the means known today did not allow to obtain.

On peut en outre citer le fait que le pré-encollage extérieur permet à la charge de ne jamais être tâchée ou collée. En outre, compte-tenu de la possibilité de stocker la bobine de papier sous forme horizontale, l'ensemble automatique géré par un automate programmable peut présenter une très grande autonomie et par voie de conséquence, permet une économie de manoeuvres appréciable.We can also cite the fact that the external pre-gluing allows the load never to be stained or stuck. In addition, taking into account the possibility of storing the paper reel in horizontal form, the automatic assembly managed by a programmable automaton can have a very great autonomy and consequently, allows an appreciable saving of maneuvers.
