A carriage (8) moving on the arms has a film unwinding device and a film folding arm. The film folding arm changes orientation of a film (10) when the film is situated above an upper side of the pallet to flatten the film on the upper side, when the carriage descends. An independent claim is also included for a stretch wrapping process of an upper side of a load.

Description

L'invention concerne une machine d'emballage ou de banderolage sous un film, par exemple de matière plastique étirable, notamment de produits empilés sur une palette, et un procédé de banderolage mis en oeuvre par cette machine, également appelée banderoleuse.The invention relates to a wrapping machine or wrapping under a film, for example of stretchable plastic material, in particular products stacked on a pallet, and a wrapping process implemented by this machine, also called wrapping machine.

Il est courant d'emballer des palettes sous un film plastique étirable. De nombreux procédés existent en ce qui concerne l'emballage des faces latérales des palettes, mais il est plus compliqué de recouvrir également la face supérieure, globalement horizontale, de la palette. Pourtant, certaines palettes, en fonction de leur contenu, nécessitent la couverture de cette face supérieure, que ce soit pour des raisons de tenue de la palette, d'étanchéité à la poussière ou à l'eau, etc.It is common to pack pallets under stretch plastic film. Of many processes exist with regard to the packaging of the side faces pallets, but it is more complicated to also cover the face upper, generally horizontal, palette. Yet some pallets, in according to their content, require the cover of this upper face, that this is for reasons of holding the pallet, sealing to dust or water, etc.

On connaít, par exemple par le brevet français FR 90 09059, un procédé permettant de banderoler la face supérieure d'une palette. Dans ce procédé, le film, supporté par un chariot, est déroulé au-dessus de la face supérieure de la palette et orienté de façon à être plaqué sur cette face lorsque le chariot est redescendu.It is known, for example from the French patent FR 90 09059, a method allowing to wrap the upper face of a pallet. In this process, the film, supported by a trolley, is unrolled over the upper face of the pallet and oriented so as to be plated on that face when the carriage is back down.

Pour la mise en oeuvre de ce procédé, on utilise une machine comportant une table tournante, sur laquelle est disposée la palette, un support comprenant un bras vertical sur lequel un chariot, supportant un dispositif de déroulement du film, est mobile en translation verticale ; le dispositif de déroulement est monté rotatif, autour d'un axe horizontal, sur le chariot. Ainsi, il est possible, lors de la rotation de la table, de déplacer le chariot au-dessus de la face supérieure de la palette et d'incliner le dispositif de déroulement du film de façon à appliquer ce dernier horizontalement sur la face supérieure de la palette lorsque le chariot est redescendu.For the implementation of this method, a machine comprising a turntable, on which is disposed the pallet, a support comprising a vertical arm on which a carriage, supporting an unwinding device of the film, is mobile in vertical translation; the unwinding device is mounted rotating around a horizontal axis on the carriage. So, it is possible, during the rotation of the table, to move the carriage over the upper face of the pallet and tilt the film unwinding device so as to apply this last horizontally on the upper face of the pallet when the carriage is back down.

Toutefois, les moyens d'entraínement en rotation du dispositif de déroulement du film sont complexes et conduisent à des coûts de production importants, notamment si l'on décide d'ajouter la fonction de banderolage de la face supérieure de la palette à une machine ne pouvant à l'origine banderoler que les faces latérales. Par ailleurs, une telle ne permet pas d'atteindre des vitesses de banderolage très élevées et doit de surcroít délivrer un film d'une largeur suffisante pour atteindre le centre de la face supérieure de la palette, ce film ne pouvant être pré-étiré de façon significative ; la consommation de film est par conséquent importante. Ce type de machine est de plus peu modulable.However, the means for rotating the device of unwinding of the film are complex and lead to production costs important, especially if it is decided to add the wrapping function of the upper face of the pallet to a machine that can not originally banderoler than the side faces. Moreover, such does not achieve speeds of very high wrapping and must additionally deliver a film with a width enough to reach the center of the upper face of the pallet, this film does not can be pre-stretched significantly; film consumption is by important. This type of machine is more flexible.

La présente invention vise à pallier tout et partie des inconvénients mentionnés ci-dessus. The present invention aims to overcome all and some of the disadvantages mentioned above.

A cet effet, l'invention concerne une machine de banderolage d'une charge sous un film, comprenant un châssis, une table, montée sur le châssis et sur laquelle est disposée la charge, au moins un bras, mobile en rotation par rapport au châssis le supportant, un chariot monté sur le bras, mobile en translation sur le bras et comportant un dispositif de déroulement du film et un dispositif de plissage du film, caractérisé par le fait que le dispositif de plissage du film est agencé pour, en cours de banderolage, changer l'orientation du film.For this purpose, the invention relates to a wrapping machine of a load under a film, comprising a frame, a table, mounted on the frame and on which the load is arranged, at least one arm rotatable by to the frame supporting it, a carriage mounted on the arm, movable in translation on the arm and comprising a film unwinding device and a pleating device of the film, characterized in that the pleating device The film is arranged to, during wrapping, change the orientation of the film.

Grâce à la machine de l'invention, le dispositif de plissage est utilisé pour orienter le film, lorsqu'il est situé au-dessus de la face supérieure de la charge, de façon à le plaquer sur la face supérieure de la charge lorsque le chariot est redescendu. Ainsi, il est possible d'effectuer, grâce à la machine de l'invention, des opérations de recouvrement de la face supérieure d'une palette.Thanks to the machine of the invention, the pleating device is used to orient the film, when it is located above the upper face of the load, so as to flatten it on the upper face of the load when the cart has come down. Thus, it is possible to perform, thanks to the machine of the invention, recovery operations of the upper face of a pallet.

Cette fonctionnalité peut être obtenue, à partir d'une machine de l'art antérieur, grâce à des changements sommaires et peu coûteux.This feature can be obtained from an art machine previous, thanks to summary and inexpensive changes.

De préférence, le dispositif de plissage comprend un bras pouvant pivoter dans un plan sensiblement vertical.Preferably, the pleating device comprises an arm that can rotate in a substantially vertical plane.

De préférence encore, le plan de pivotement du bras du dispositif de plissage peut être entraíné en rotation par rapport au chariot autour d'un axe sensiblement vertical.More preferably, the pivot plane of the arm of the pleating can be rotated relative to the carriage about an axis substantially vertical.

Ainsi, il est possible d'améliorer l'orientation du film par réglage du plan de pivotement du bras du dispositif de plissage, sans que cela n'influe sur la fonction de plissage du dispositif de plissage.Thus, it is possible to improve the orientation of the film by adjusting the plane pivoting arm of the pleating device, without this affecting the pleating function of the pleating device.

De préférence toujours, le dispositif de plissage comprend des moyens gênant le plissage du film lorsque le dispositif est employé pour l'orientation du film.Preferably still, the pleating device comprises means annoying the pleating of the film when the device is used for the orientation of the movie.

Avantageusement, ces moyens comprennent des bagues de caoutchouc disposées le long du bras du dispositif de plissage.Advantageously, these means comprise rubber rings arranged along the arm of the pleating device.

Dans sa forme de réalisation préférée, la machine comprend deux bras.In its preferred embodiment, the machine comprises two arms.

Dans ce cas, il est possible, grâce à la machine de l'invention, d'élever les chariots au-dessus de la face supérieure de la charge, d'abaisser les bras des dispositifs de plissage et de redescendre les chariots de façon à ce que les films se croisent avant d'être plaqués sur la face supérieure de la charge. In this case, it is possible, thanks to the machine of the invention, to raise the trolleys above the upper face of the load, to lower the arms of the pleating devices and down the trolleys so that the films intersect before being tacked on the upper face of the load.

Ainsi, il est possible, d'une part, d'atteindre le centre de la charge en utilisant un film de largeur plus faible que dans le procédé du brevet FR 90 09059, d'autre part, d'effectuer une sorte de noeud de film au milieu de la face supérieure de la charge, ce qui permet un recouvrement de film plus serré et plus stable. L'étanchéité du recouvrement est de la sorte plus sûre.Thus, it is possible, on the one hand, to reach the center of the load by using a film of smaller width than in the method of the FR 90 patent 09059, on the other hand, to perform a kind of movie knot in the middle of the face top of the load, which allows for a tighter film coverage and more stable. The sealing of the cover is thus safer.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée de la machine de banderolage de l'invention et du procédé la mettant en oeuvre, en référence au dessin annexé, sur lequel :

The invention will be better understood with the aid of the following description of the preferred embodiment of the wrapping machine of the invention and of the method implementing it, with reference to the appended drawing, in which:
  • Figure 1 shows a side view of the wrapping machine of the invention;
  • Figure 2 shows a perspective view from above of the carriage provided with the pleating device of the invention;
  • Figure 3 shows a schematic side view of the pleating device of Figure 2, parallel to the plane II-II, in two positions;

  • FIG. 5 represents a schematic illustration of the result of the process of FIG. 4.

En référence à la figure 1, la machine de banderolage 1 de l'invention, appelée également banderoleuse, comprend un châssis 2, dont une partie en forme de potence supporte une poutre horizontale 3. Aux deux extrémités de la poutre 3 sont fixés des bras verticaux 4, 4'. La poutre 3 et les bras 4, 4' sont entraínés en rotation, autour d'un axe vertical 5, par un moteur, non représenté.With reference to FIG. 1, the wrapping machine 1 of the invention, also called a wrapping machine, comprises a frame 2, a part of which stem form supports a horizontal beam 3. At both ends of the beam 3 are fixed vertical arms 4, 4 '. The beam 3 and the arms 4, 4 'are driven in rotation, about a vertical axis 5, by a motor, not shown.

La machine 1 comprend également une table 6, montée sur le châssis 2. La table 6 est ici montée sur des galets afin de pouvoir tourner sur elle-même, sous l'action d'un autre moteur, non représenté, autour de l'axe 5 ; cette fonction est utile pour certains procédés de banderolage, mais n'est pas nécessaire à la mise en oeuvre de l'invention. Une palette 7 à banderoler est disposée sur la table 6. La palette 7 est la charge de la table 6.The machine 1 also comprises a table 6, mounted on the frame 2. The table 6 is here mounted on rollers in order to turn on itself, under the action of another motor, not shown, around the axis 5; this function is useful for some wrapping processes, but is not necessary for implementation of the invention. A pallet 7 to be wrapped is arranged on the table 6. Pallet 7 is the load of table 6.

Chaque bras 4, 4' supporte un chariot 8, 8', respectivement, mobile en translation le long du bras 4, 4'. Les chariots 8, 8' sont par exemple entraínés par des chaínes reliées à des moteurs, non représentés. Un moteur unique peut être employé pour l'entraínement des deux chariots 8, 8'. Chaque chariot 8, 8' supporte une bobine 9, 9' de film 10, 10', respectivement.Each arm 4, 4 'supports a carriage 8, 8', respectively, movable in translation along the arm 4, 4 '. The trolleys 8, 8 'are for example driven by chains connected to motors, not shown. A single engine can be used for the drive of the two carriages 8, 8 '. Each carriage 8, 8 ' supports a coil 9, 9 'of film 10, 10', respectively.

La figure 2 représente un chariot 8, l'autre chariot 8' lui étant identique. Le chariot 8 comprend un châssis 11, supportant la bobine 9 de film 10 et des rouleaux 12, 13, 14, 15, 16 de déroulement et de pré-étirage du film 10. En aval du dernier rouleau de déroulement 16, le film 10 s'étend vers la palette 7 à banderoler, et passe devant un bras de plissage 20, à savoir entre la palette 7 et le bras de plissage 20, sans forcément, en régime normal, être en contact avec le bras de plissage 20, et vient en appui sur la périphérie arrière, par rapport à la palette 7, d'un rouleau de détour 17.Figure 2 shows a carriage 8, the other carriage 8 'being identical thereto. The carriage 8 comprises a frame 11 supporting the film reel 9 and rolls 12, 13, 14, 15, 16 for unwinding and prestretching the film 10. Downstream of the last unwinding roll 16, the film 10 extends to the pallet 7 to wrapping, and passes in front of a pleating arm 20, namely between the pallet 7 and the pleating arm 20, without necessarily, in normal operation, be in contact with the pleating arm 20, and abuts on the rear periphery, with respect to the pallet 7, of a detour roll 17.

Il convient de noter que le chariot 8 de la figure 2 est représenté en perspective, notamment parce qu'il existe un angle non plat entre la partie de son châssis 11 supportant les rouleaux de déroulement et de pré-étirage 12-16 et celle supportant le bras de plissage 20 et le rouleau 17. Toutefois, le film n'a été représenté que par un trait, même au niveau de la seconde partie du châssis 11 susmentionnée, pour des raisons de clarté.It should be noted that the carriage 8 of FIG. 2 is shown in FIG. perspective, particularly because there is a non-flat angle between the part of his frame 11 supporting the unwinding and pre-stretching rolls 12-16 and that supporting the pleating arm 20 and the roller 17. However, the film has not been represented only by a line, even at the level of the second part of the chassis 11 above, for the sake of clarity.

En référence aux figures 2 et 3, le bras de plissage 20 peut pivoter dans un plan II-II sensiblement vertical, vers le bas dans le sens de la rotation des bras 4, 4'. Sur la figure 3, on voit deux positions successives prises par le bras 20, l'une verticale 20', l'autre inclinée 20". Le pivotement du bras de plissage 20 est assuré par un moteur (non représenté). Le rouleau de détour 17 pivote ici de la même façon que le bras 20.With reference to FIGS. 2 and 3, the pleating arm 20 can pivot in a substantially vertical plane II-II, downwards in the direction of rotation of the arms 4, 4 '. FIG. 3 shows two successive positions taken by the arm 20, one vertical 20 ', the other inclined 20. "The pivoting of the pleating arm 20 is provided by a motor (not shown). The detour roll 17 pivots here from the same way as the arm 20.

Dans la banderoleuse 1 ici décrite, le plan de pivotement II-II du bras de plissage 20 est réglable par rotation autour de l'axe vertical 21 que suit le bras en position verticale. Il est donc possible de faire pivoter ce plan en direction de la palette 7, c'est-à-dire de façon à ce que le bras de plissage pivote dans un plan vertical en direction de la palette 7.In the wrapping machine 1 described here, the pivot plane II-II of the arm of pleating 20 is adjustable by rotation about the vertical axis 21 that follows the arm in vertical position. It is therefore possible to rotate this plane towards the pallet 7, that is to say, so that the pleating arm pivots in a plane vertical towards the pallet 7.

Il est encore possible, lorsque le chariot 8 se trouve à une hauteur supérieure à celle de la face supérieure 22 de la palette 7, d'abaisser le bras de plissage 20, ce qui a pour conséquence, en raison de la position du film 10 dans ce cas, non pas de le plisser mais de l'orienter dans la direction de la face supérieure 22 de la palette 7.It is still possible, when the carriage 8 is at a height greater than that of the upper face 22 of the pallet 7, to lower the arm of pleating 20, which has the consequence, because of the position of the film 10 in this case, not to wrinkle it but to orient it in the direction of the face upper 22 of the pallet 7.

Dans le but d'éviter au maximum le plissage et de favoriser l'orientation du film 10 dans ce cas-là, le bras de plissage 20 est pourvu sur sa longueur de bagues cylindriques de caoutchouc 23. Ces bagues 23 agissent en quelque sorte comme les doigts d'une main pour maintenir le film 10 à plat et ne pas le plisser. L'avantage de la solution retenue est que, lors du banderolage des faces latérales de la palette 7, un pivotement du bras de plissage 20 provoque bien le plissage du film 10, en raison de la position de ce dernier.In order to avoid pleating as much as possible and to favor orientation of the film 10 in this case, the pleating arm 20 is provided along its length. cylindrical rubber rings 23. These rings 23 act somehow like the fingers of a hand to hold the film 10 flat and not wrinkle it. The advantage of the solution retained is that, when wrapping the lateral faces of the pallet 7, a pivoting of the pleating arm 20 causes the pleating of film 10, because of the position of the latter.

Le fonctionnement de la machine de banderolage de l'invention va maintenant être expliqué plus en détail. The operation of the wrapping machine of the invention will now be explained in more detail.

La palette 7 est positionnée sur la table 6 pour être banderolée. D'une façon générale, la palette 7 est amenée sur la table 6 par un système de convoyage, comportant des rouleaux, non représentés. La table 6 comprend également un système de convoyage similaire afin de compléter l'autre système de convoyage et de positionner la palette 7 précisément.The pallet 7 is positioned on the table 6 to be banded. On the one generally, the pallet 7 is brought onto the table 6 by a system of conveying, comprising rollers, not shown. Table 6 includes also a similar conveyor system to complement the other system conveying and positioning the pallet 7 precisely.

Lors du début d'un cycle de fonctionnement classique de la machine 1, les films 10, 10' sont bloqués à leur extrémité libre par des dispositifs 18, 18' permettant de les pincer, de les souder et de les couper, que l'on désigne par la suite par le terme de pinces 18, 18'. Ce type de dispositif est bien connu de l'homme du métier. Les chariots 8, 8' sont placés dans la partie basse des bras 4, 4', c'est-à-dire en bas de la palette 7, à proximité des pinces 18, 18'. Les bras 4, 4' sont ensuite mis en rotation autour de la table 6. Cela a pour effet d'étirer les films 10, 10' et de les plaquer, au fur et à mesure de la rotation, contre la palette 7. Les films, initialement plissés par les pinces 18, 18', se déroulent rapidement à leur largeur normale. Lors du premier demi-tour, les chariots 8, 8' sont élevés sur les bras 4, 4' de façon à se trouver au-dessus des pinces lorsqu'ils repassent au point de départ des films 10, 10'. Il est ainsi possible d'escamoter les pinces 18, 18' et de continuer la rotation, les films 10, 10', après le premier demi-tour, recouvrant la première couche de films 10, 10' après leur partie plissée.At the beginning of a typical operating cycle of machine 1, the films 10, 10 'are locked at their free end by devices 18, 18' to pinch, weld and cut them, which is referred to as the next by the term of tongs 18, 18 '. This type of device is well known the skilled person. The trolleys 8, 8 'are placed in the lower part of the arms 4, 4 ', that is to say at the bottom of the pallet 7, near the clamps 18, 18'. The arms 4, 4 ' are then rotated around table 6. This has the effect of stretching films 10, 10 'and to flatten them, as and when rotation, against the pallet 7. The films, initially folded by the clamps 18, 18 ', proceed rapidly to their normal width. During the first half-turn, the carriages 8, 8 'are raised on the arms 4, 4 'so as to be above the clamps when they go back to the starting point of the films 10, 10 '. It is thus possible to retract the clamps 18, 18 'and continue the rotation, the films 10, 10', after the first half-turn, covering the first layer of films 10, 10 'after their folded part.

Lors de la fin d'un cycle de fonctionnement classique de la machine 1, les films 10, 10' sont descendus au niveau des pinces 18, 18', sont plissés par un pivotement des bras de plissage 20, avant d'être pincés, soudés et coupés par les pinces 18, 18', selon un procédé classique de l'art antérieur. La machine 1 est alors prête pour un nouveau cycle.At the end of a typical cycle of operation of the machine 1, the films 10, 10 'are lowered at the clamps 18, 18', are folded by a pivoting of the pleating arms 20, before being pinched, welded and cut by the clamps 18, 18 ', according to a conventional method of the prior art. Machine 1 is then ready for a new cycle.

Le début et la fin du cycle de fonctionnement de la machine 1 de l'invention sont tout à fait semblables à ceux des machines de l'art antérieur. Les bras de plissage 20 des chariots 8, 8' y exercent d'ailleurs une fonction identique, seule leur structure différant.The beginning and the end of the operating cycle of machine 1 the invention are quite similar to those of the machines of the prior art. The pleating arm 20 trolleys 8, 8 'also exert an identical function, only their different structure.

Toutefois, les bras de plissage 20 de la machine de l'invention, de par leur structure, peuvent remplir une seconde fonction : ils permettent d'assurer l'orientation des films 10, 10' pour faciliter le banderolage de la face supérieure 22 de la palette 7.However, the pleating arms 20 of the machine of the invention, by their structure, can fulfill a second function: they make it possible to ensure the orientation of the films 10, 10 'to facilitate the wrapping of the upper face 22 of the pallet 7.

Ainsi, afin d'appliquer une portion de bande de film 10 sur la face supérieure 22 de la palette 7, le chariot 8, par exemple, en général après un passage en face d'une arête de la palette 7, est élevé au-dessus de la face supérieure 22 de la palette 7. Le bras de plissage 20 est alors entraíné de sa position verticale 20' à une position inclinée 20", afin d'orienter la surface du film 10 vers la face supérieure 22 de la palette 7. Le chariot 8 est ensuite abaissé en dessous du niveau de la face supérieure 22 de la palette 7, ce qui provoque le placage du film 10 sur la face supérieure 22 de la palette 7. Le bras de plissage 20 est enfin entraíné de nouveau en position verticale pour effectuer le banderolage classique des faces latérales.So, in order to apply a portion of film strip 10 on the face 22 of the pallet 7, the carriage 8, for example, in general after a passage in front of an edge of the pallet 7, is raised above the face 22 of the pallet 7. The pleating arm 20 is then driven by its vertical position 20 'at an inclined position 20 "so as to orient the surface of the film 10 to the upper face 22 of the pallet 7. The carriage 8 is then lowered below the level of the upper face 22 of the pallet 7, which causes the plating of the film 10 on the upper face 22 of the pallet 7. The pleating arm 20 is finally driven back to the upright position to perform the classical wrapping of the lateral faces.

La machine 1 permet la mise en oeuvre d'un procédé particulier, dans la mesure où la légèreté du dispositif d'orientation du film, à savoir le bras de plissage 20, autorise la rotation simultanée de deux bras 4, 4', comportant chacun un tel dispositif 20. Ainsi, il est possible de lever et baisser les chariots 8, 8', tout en abaissant les bras de plissage 20 à un moment approprié, de façon à provoquer le croisement des films 10, 10' avant leur placage sur la face supérieure 22 de la palette 7. Ce procédé de recouvrement a pour intérêt, non seulement d'atteindre le centre de la face supérieure 22 de la palette 7 avec des films 10, 10' de largeur moindre que dans l'art antérieur, mais aussi d'effectuer une sorte de noeud avec les films 10, 10', ce qui garantie une meilleure tenue du banderolage.The machine 1 allows the implementation of a particular method, in the the lightness of the film orientation device, namely the arm of pleating 20, allows the simultaneous rotation of two arms 4, 4 ', comprising each such device 20. Thus, it is possible to raise and lower the carriages 8, 8 ', while lowering the pleating arms 20 at a suitable time, so as to cause the crossing of the films 10, 10 'before their plating on the face 22 of the pallet 7. This method of recovery is useful, not only to reach the center of the upper face 22 of the pallet 7 with 10 ', 10' of smaller width than in the prior art, but also to perform a kind of knot with the films 10, 10 ', which guarantees a better performance of the wrapping.

Les figures 4 et 5 illustrent un exemple de procédé de banderolage de la face supérieure 22 d'une palette 7 utilisant le croisement des films 10, 10' expliqué ce-dessus. Sur la figure 4, trois graphes illustrent ce procédé, exécuté en trois tours des bras 4, 4' ; en abscisse est représenté l'angle que fait la poutre 3 par rapport à une position de départ et en ordonnée est représentée la hauteur des chariots 8, 8', identique pour les deux. Sur ces graphes, h représente la hauteur de la face supérieure 22 de la palette 7, h0 une hauteur située en dessous, h1, h2, h3 trois hauteurs différentes situées au-dessus.Figures 4 and 5 illustrate an example of a method of wrapping the upper face 22 of a pallet 7 using the crossing of the films 10, 10 ' explained above. In FIG. 4, three graphs illustrate this method, executed in three turns of arms 4, 4 '; on the abscissa is represented the angle made by the beam 3 relative to a starting position and on the ordinate is represented the height of the carriages 8, 8 ', identical for both. On these graphs, h is the height of the upper face 22 of the pallet 7, h0 a height below, h1, h2, h3 three different heights located above.

Lors du premier tour de la poutre 3, les chariots 8, 8' sont rapidement élevés, à partir la hauteur h0 de la position de départ, dans laquelle ils sont sensiblement en face d'une arête de 1a palette 7, jusqu'à la hauteur h1, qu'ils atteignent après environ 15° de rotation. Dans une position notée P1, située après environ 60° de rotation, les dispositifs de plissage 20 sont abaissés. Les chariots 8, 8' sont redescendus jusqu'à la hauteur h0 à partir d'environ 110° de rotation jusqu'à 180°. Le tour se termine à la hauteur h0, les bras de plissage 20 étant relevés pendant cette rotation.During the first turn of the beam 3, the carriages 8, 8 'are rapidly high, from the height h0 of the starting position, in which they are substantially opposite an edge of the pallet 7, to the height h1, that they reach after about 15 ° of rotation. In a position marked P1, located after about 60 ° of rotation, the pleating devices 20 are lowered. The trolleys 8, 8 'have gone down to the height h0 from about 110.degree. rotation up to 180 °. The round ends at the height h0, the pleating arms 20 being raised during this rotation.

Les films 10, 10' recouvrent de cette façon deux coins opposés de la face supérieure 22 de la palette 7, comme on le voit schématiquement sur la figure 5, dans les positions notées 101, 101'.The films 10, 10 'thus cover two opposite corners of the face upper 22 of the pallet 7, as schematically shown in FIG. 5, in the positions noted 101, 101 '.

Lors du deuxième tour de la poutre 3, les chariots 8, 8' sont de nouveau rapidement élevés, à partir la hauteur h0, mais cette fois après avoir déjà effectué environ 25° de rotation, c'est-à-dire après 385° de rotation depuis le début du procédé, pour atteindre une hauteur h2, supérieure à h1, après environ 15° de rotation. Dans une position notée P2, située après environ 460° de rotation depuis le début du procédé, les dispositifs de plissage 20 sont abaissés. Les chariots 8, 8' sont redescendus jusqu'à la hauteur h0 à partir d'environ 510° de rotation jusqu'à 540°. Le tour se termine à la hauteur h0, les bras de plissage 20 étant relevés pendant cette rotation.During the second turn of the beam 3, the carriages 8, 8 'are again quickly high, from height h0, but this time after already having approximately 25 ° of rotation, that is to say after 385 ° rotation since the beginning of the process, to reach a height h2, greater than h1, after about 15 ° rotation. In a position noted P2, located after about 460 ° of rotation from the beginning of the process, the pleating devices 20 are lowered. The trolleys 8, 8 'are descended to the height h0 from about 510 ° rotation up to 540 °. The lap ends at height h0, the pleating arms 20 being raised during this rotation.

Les films recouvrent de cette façon deux bandes opposées complétant les coins précédents vers le centre de la face supérieure 22 de la palette 7, comme on le voit dans les positions 102, 102' de la figure 5.The films cover in this way two opposite bands completing the previous corners towards the center of the upper face 22 of the pallet 7, as it can be seen in the positions 102, 102 'of FIG.

Lors du troisième et dernier tour de la poutre 3, les chariots 8, 8' sont encore rapidement élevés, à partir la hauteur h0, mais cette fois après avoir déjà effectué environ 25° de rotation, c'est-à-dire après 755° de rotation depuis le début du procédé, pour atteindre une hauteur h3, supérieure à h2, après environ 15° de rotation. Dans une position notée P3, située après environ 880° de rotation depuis le début du procédé, les dispositifs de plissage 20 sont abaissés. Les chariots 8, 8' sont redescendus jusqu'à la hauteur h0 à partir d'environ 890° de rotation jusqu'à 940°. De cette façon, ils se croisent avant d'être plaqués sur la face supérieure 22 de la palette 7. Le tour se termine à la hauteur h0, les bras de plissage 20 étant relevés pendant cette rotation.During the third and last turn of the beam 3, the carriages 8, 8 'are still quickly high, from height h0, but this time after already having approximately 25 ° of rotation, that is to say after 755 ° rotation since the beginning of the process, to reach a height h3, greater than h2, after about 15 ° rotation. In a position marked P3, located after about 880 ° of rotation from the beginning of the process, the pleating devices 20 are lowered. The carriages 8, 8 'are descended to the height h0 from about 890 ° rotation up to 940 °. In this way, they cross each other before being tackled on the upper face 22 of the pallet 7. The turn ends at height h0, the arms of pleating 20 being raised during this rotation.

Les films recouvrent de cette façon une bande centrale de la face supérieure 22 de la palette 7, comme on le voit dans les positions 103, 103' de la figure 5 ; on remarque sur cette dernière une zone de croisement 100 entre les films 10, 10', qui sont ainsi, non seulement plaqués sur la palette 7, mais également, en quelque sorte, noués l'un à l'autre.The films cover in this way a central band of the face 22 of the pallet 7, as seen in the positions 103, 103 'of the Figure 5; we notice on the latter a crossing zone 100 between films 10, 10 ', which are thus not only plated on the pallet 7, but also, somehow, knotted one to the other.

Grâce à la machine 1 de l'invention, il est donc possible de banderoler la face supérieure 22 de la palette 7 avec des films 10, 10' moins larges que dans l'art antérieur et avec une grande vitesse d'exécution, du fait de la présence de deux bras 4, 4'.Thanks to the machine 1 of the invention, it is therefore possible to wrap the upper face 22 of the pallet 7 with films 10, 10 'narrower than in the prior art and with a high speed of execution, because of the presence of two arms 4, 4 '.

Le plan de pivotement du bras de plissage 20 de l'invention est ici réglable par rotation autour de l'axe 21. Il est tout à fait envisageable que ce réglage puisse être fait en continu, c'est-à-dire que le plan de pivotement du bras de plissage 20 puisse être entraíné en rotation, par rapport au chariot 8 supportant le bras 20, en cours de procédé de banderolage, pour par exemple changer l'orientation du film 10 de ce fait.The pivoting plane of the pleating arm 20 of the invention is here rotationally adjustable about the axis 21. It is quite possible that this adjustment can be made continuously, that is to say that the pivot plane of the arm pleating 20 can be driven in rotation, with respect to the carriage 8 supporting the arm 20 during the wrapping process, for example change the orientation of the film 10 thereby.
