Description

Dispositif de support de pièces de carrosserie comprenant au moins un organe de support orientable  Bodywork support device comprising at least one pivotable support member
L'invention concerne le domaine de la peinture de pièces de carrosserie de véhicules automobiles. En particulier l'invention concerne un dispositif de support de pièces de carrosserie lors de la peinture de ces pièces de carrosserie, une installation de peinture comportant un tel dispositif de support, ainsi qu'un procédé de peinture dans une telle installation. The invention relates to the field of painting automotive body parts. In particular, the invention relates to a device for supporting bodywork parts during the painting of these bodywork parts, a painting installation comprising such a support device, as well as a painting method in such an installation.
La peinture des pièces de véhicules automobiles est souvent réalisée dans une chaîne peinture, qui est une installation dans laquelle des balancelles circulent l'une à la suite de l'autre à travers une succession de postes. Les balancelles constituent des organes de support des pièces à peindre. Ces balancelles sont disposées sur des supports formant des mâts. Un mât constitue sensiblement un corps longiligne. Les mâts sont eux- mêmes positionnés sensiblement verticalement sur des cadres appelés luges. Les luges sont positionnées sur un convoyeur et sont donc mobiles. Elles parcourent toute la chaîne de peinture : depuis le chargement de la pièce sur les balancelles supportées par les mâts, jusqu'au déchargement en sortie de la chaîne de peinture, en passant par les différents postes de peinture permettant d'appliquer primaire, base et vernis sur les pièces, postes au niveau desquels évoluent des robots peintres.  The painting of motor vehicle parts is often carried out in a paint line, which is an installation in which swings are moving one after the other through a succession of stations. Swings are support organs for the parts to be painted. These swings are arranged on supports forming poles. A mast is substantially an elongated body. The masts themselves are positioned substantially vertically on frames called sleds. The sleds are positioned on a conveyor and are therefore mobile. They run the entire painting chain: from the loading of the part on the swing supports supported by the masts, to the unloading at the exit of the painting chain, through the various paint stations allowing to apply primary, base and varnish on the pieces, posts at which evolve painters robots.
Les balancelles, le mât et la luge constituent un dispositif de support pour pièces de carrosserie lors de la peinture de ces pièces de carrosserie.  Swings, mast and sled constitute a support device for body parts during the painting of these body parts.
On connaît déjà, dans l'état de la technique, un tel dispositif de support, du type comportant un ou plusieurs organes de support (balancelles), portés par un mât sensiblement vertical, chaque support étant destiné à supporter au moins une pièce de carrosserie.  Already known in the state of the art, such a support device, of the type comprising one or more support members (swing), carried by a substantially vertical mast, each support being intended to support at least one body part .
Dans l'état de la technique, le mât et les organes de support sont montés fixes sur le cadre. Dès lors, lorsque le dispositif de support est immobilisé devant un robot peintre, ce dernier doit bouger autour des pièces de carrosserie à peindre. Dans le cas de certaines pièces de carrosserie, comme par exemple les becquets, le robot peintre doit peindre beaucoup des zones différentes de la pièce (par exemple la face avant, les faces latérales et l'arête arrière d'un becquet).  In the state of the art, the mast and the support members are fixedly mounted on the frame. Therefore, when the support device is immobilized in front of a painter robot, it must move around the body parts to paint. In the case of certain body parts, such as spoilers, the painter robot must paint many different areas of the room (for example the front face, the side faces and the rear edge of a spoiler).
Afin de réaliser cela, le robot peintre doit effectuer de grands mouvements tout autour des pièces de carrosserie à peindre afin d'avoir accès à toutes les faces à peindre à cause de la taille des applicateurs de peinture et des différents axes de rotation du robot peintre.  In order to achieve this, the painter robot must make great movements all around the body parts to be painted in order to have access to all the faces to be painted because of the size of the paint applicators and the different axes of rotation of the painter robot. .
Cela présente plusieurs inconvénients.  This has several disadvantages.
Tout d'abord, la programmation du robot peintre est complexe car elle doit prendre en compte le fait que le robot doit effectuer de grands mouvements autour des pièces de carrosserie. First of all, the programming of the painter robot is complex because it must take into the fact that the robot has to make big movements around the body parts.
De plus, le fait que le robot doive effectuer de grands mouvements oblige le dispositif de support à stationner un certain temps à proximité du robot peintre, le temps que ce dernier puisse peindre toutes les zones des pièces de carrosserie devant être peintes. Cela limite le rendement de la chaîne de peinture.  In addition, the fact that the robot must perform large movements forces the support device to park for some time near the painter robot, the time it can paint all areas of the body parts to be painted. This limits the performance of the paint line.
Enfin, le robot peintre devant avoir accès à de nombreuses faces des pièces à peindre dans certains cas, il est nécessaire de ménager un espace minimal entre les différentes pièces de carrosserie portées par un même dispositif de support afin que le robot peintre puisse passer entre elles. Cela limite le nombre de pièces de carrosserie pouvant être portées par un même dispositif de support et par conséquent le rendement de la chaîne de peinture. Cela est particulièrement vrai pour la peinture de l'arête arrière d'un becquet, le bras robotisé devant plier l'axe (le poignet) qui tient l'applicateur peinture, avec un encombrement particulièrement important. Étant donné que, dans les chaînes de peinture existantes, les passages entre les différents postes de peinture sont étroits, ces dispositifs de support de pièces ne peuvent par conséquent pas être trop volumineux. Cette contrainte combinée à celle précitée concernant les nombreuses faces des pièces à peindre limite très fortement le nombre de pièces pouvant être portées par un même dispositif de support.  Finally, the painter robot having access to many faces of the parts to be painted in some cases, it is necessary to provide a minimum space between the different body parts carried by the same support device so that the painter robot can pass between them . This limits the number of body parts that can be carried by the same support device and therefore the performance of the paint line. This is especially true for painting the rear edge of a spoiler, the robotic arm having to bend the axis (the wrist) that holds the paint applicator, with a particularly large footprint. Since in the existing paint lines, the passages between the different paint stations are narrow, these parts support devices can not therefore be too bulky. This constraint combined with that mentioned above concerning the many faces of the parts to be painted greatly limits the number of parts that can be carried by the same support device.
L'état de la technique comprend également des dispositifs de support de petites pièces de véhicule automobile destinés à porter ces pièces lors du procédé de peinture de ces dernières, comme par exemple des rétroviseurs extérieurs ou encore des enjoliveurs, mais ces dispositifs de support ne sont pas utilisables pour peindre des pièces de carrosserie automobile (d'une taille beaucoup trop importante pour cela, par exemple un becquet d'une longueur d'environ 1 ,40 m et d'une largeur allant d'environ 10 à 50 cm, avec un retour au niveau de l'arête arrière d'environ 20 mm, un retour au niveau de l'arête avant d'environ 50 mm et un retour au niveau des extrémités latérales d'environ 20 à 100 mm).  The state of the art also comprises devices for supporting small parts of a motor vehicle intended to carry these parts during the painting process of the latter, such as for example external mirrors or hubcaps, but these support devices are not not usable to paint automobile body parts (of a size much too important for this, for example a spoiler with a length of about 1, 40 m and a width of about 10 to 50 cm, with a return to the rear edge of about 20 mm, a return to the front edge of about 50 mm and a return at the lateral ends of about 20 to 100 mm).
L'état de la technique comprend enfin des dispositifs de peinture comprenant un bras articulé qui, à l'aide d'un préhenseur, déplace une pièce de carrosserie automobile devant au moins un applicateur de peinture fixe afin de peindre cette dernière. Cependant, la mobilité de la pièce de carrosserie devant l'applicateur de peinture peut provoquer l'apparition de coulures de peinture sur cette dernière.  The state of the art finally comprises painting devices comprising an articulated arm which, with the aid of a gripper, moves an automobile bodywork part in front of at least one fixed paint applicator in order to paint the latter. However, the mobility of the body part in front of the paint applicator can cause the appearance of paint drift on the latter.
Le but de l'invention est de remédier aux inconvénients précités en fournissant un dispositif de support de pièces de carrosserie à peindre permettant de simplifier la trajectoire des robots peintre et d'augmenter le rendement de la chaîne de peinture.  The object of the invention is to overcome the aforementioned drawbacks by providing a bodywork support device to paint to simplify the path of the paint robots and increase the performance of the paint line.
L'invention a pour objet un dispositif de support de pièces de carrosserie lors d'un procédé de peinture de ces pièces de carrosserie comprenant : The subject of the invention is a device for supporting bodywork parts during a method of painting these body parts comprising:
- un cadre,  - a frame,
- au moins un mât fixé au cadre,  at least one mast fixed to the frame,
- au moins un organe de support destiné à supporter les pièces de carrosserie et porté par le mât, l'organe de support étant monté mobile en rotation par rapport au mât. - At least one support member for supporting the body parts and carried by the mast, the support member being rotatably mounted relative to the mast.
Ainsi, la mobilité de l'organe de support permet de modifier l'orientation des pièces de carrosserie à peindre lorsque le dispositif de support est stationné devant un robot peintre, ce qui permet de rendre les pièces à peindre plus accessibles pour le robot peintre qui aura par conséquent des mouvements moins complexes à réaliser. La simplification des déplacements du robot peintre peut également permettre de réduire le temps de peinture. Thus, the mobility of the support member makes it possible to modify the orientation of the bodywork parts to be painted when the support device is parked in front of a painter's robot, which makes the pieces to be painted more accessible to the painter robot. will therefore have less complex movements to achieve. The simplification of the movement of the painter robot can also reduce the painting time.
Le fait de pouvoir modifier l'orientation des pièces de carrosserie permet également de disposer plus de pièces à peindre sur le dispositif de support puis de modifier l'orientation des pièces à peindre afin que le robot ait facilement accès aux zones devant être peinte sans avoir à ménager un espace substantiel autour des pièces de carrosserie.  The fact of being able to modify the orientation of the body parts also makes it possible to have more parts to paint on the support device and then to modify the orientation of the parts to be painted so that the robot has easy access to the areas to be painted without having to provide a substantial space around the body parts.

Nous allons maintenant présenter plusieurs modes de réalisation de l'invention, combinables entre eux, donnés à titre d'exemples non limitatifs et à l'appui des figures annexées sur lesquelles :  We will now present several embodiments of the invention, combinable with each other, given by way of non-limiting examples and with reference to the appended figures in which:

- les figures 7 et 8 sont des représentations schématiques d'un dispositif de support selon un quatrième mode de réalisation de l'invention, le dispositif de support étant à proximité immédiate d'un robot peintre.  FIGS. 7 and 8 are diagrammatic representations of a support device according to a fourth embodiment of the invention, the support device being in the immediate vicinity of a painter's robot.
On se réfère maintenant aux figures 1A 1 B et 2A 2B qui représentent une installation de peinture comprenant un dispositif de support 2 de pièces de carrosserie 4, par exemples des becquets, lors d'un procédé de peinture de ces pièces de carrosserie. Le dispositif de support 2 comprend un cadre (ou luge) 6 disposé sur un convoyeur et par conséquent mobile. Deux mâts 8 sont montés sur le cadre 6. Il s'agit de structures longilignes et ayant un axe principal A vertical. Plusieurs organes de support (ou balancelles) (non représentés) et destinés à supporter les pièces de carrosserie, sont portés par les mâts 8. Les organes de support, ou balancelles, sont du type utilisé dans l'état de la technique. L'ensemble cadre 6 / mâts 8 / organes de support forment le dispositif de support 2. Referring now to Figures 1A 1 B and 2A 2B which show a paint installation comprising a support device 2 of body parts 4, for example spoilers, during a painting process of these body parts. The support device 2 comprises a frame (or luge) 6 disposed on a conveyor and therefore mobile. Two masts 8 are mounted on the frame 6. They are elongate structures and having a main axis A vertical. Several support members (or swings) (not shown) and intended to support the bodywork parts are carried by the poles 8. The support members, or swings, are of the type used in the state of the art. The frame assembly 6 / masts 8 / support members form the support device 2.
Dans l'exemple illustré, le dispositif de support 2 comprend deux mâts 8 et quatre pièces de carrosserie 4 portées par quatre organes de support. Le nombre de mâts 8, et d'organes de support peuvent varier.  In the illustrated example, the support device 2 comprises two masts 8 and four bodywork parts 4 carried by four support members. The number of poles 8 and support members may vary.
Les organes de support sont mobiles en rotation. Cette rotation peut s'effectuer selon un axe perpendiculaire à l'axe principal A des mâts 8 et peut être effectuée entre deux positions extrêmes, par exemple une position dans laquelle les pièces de carrosserie sont en position horizontale et une autre position dans laquelle les pièces de carrosserie sont en position verticale, les organes de support pouvant occuper, c'est-à-dire être bloqués, au moins une position intermédiaire entre ces deux positions extrêmes. Cela permet de simplifier la trajectoire d'un robot peintre 10 et aussi le temps nécessaire pour peindre les pièces de carrosserie 4 en orientant ces dernières de manière optimale pour la peinture, par exemple en présentant successivement au robot peintre 10 les faces à peindre. Ceci est particulièrement intéressant pour peindre les arêtes à l'arrière des pièces (du côté du mât), zone pour laquelle le robot aurait dû plier l'axe (le poignet) qui tient l'applicateur peinture, avec un encombrement particulièrement important. Il est également possible de placer les pièces de carrosserie 4 en position horizontale après l'application de chaque couche de peinture, ce qui est idéal pour obtenir un tendu idéal de la peinture sur les pièces de carrosserie. De manière optimale, il est intéressant de faire sécher les pièces de carrosserie 4 en les plaçant dans une position identique à celle qu'elles occuperont une fois montées sur le véhicule afin d'obtenir ce tendu idéal. Le passage de la position horizontale à la position verticale est représenté par la flèche 12 sur les figures 1A 1 B et le passage de la position verticale à la position horizontale est représenté par la flèche 14 sur les figures 2A 2B.  The support members are movable in rotation. This rotation can be performed along an axis perpendicular to the main axis A of the poles 8 and can be performed between two extreme positions, for example a position in which the bodywork parts are in a horizontal position and another position in which the parts bodywork are in a vertical position, the support members may occupy, that is to say be blocked, at least one intermediate position between these two extreme positions. This makes it possible to simplify the trajectory of a painter's robot 10 and also the time required to paint the bodywork parts 4 by orienting the latter optimally for the painting, for example by successively presenting the painter 10 with the faces to be painted. This is particularly interesting for painting the edges at the back of the parts (on the side of the mast), area for which the robot should have bent the axis (the wrist) that holds the paint applicator, with a particularly large size. It is also possible to place the body parts 4 in a horizontal position after the application of each layer of paint, which is ideal to obtain an ideal tension of the paint on the body parts. Optimally, it is advantageous to dry the body parts 4 by placing them in a position identical to that they occupy once mounted on the vehicle to obtain this ideal tension. The transition from the horizontal position to the vertical position is represented by the arrow 12 in FIGS. 1A 1 B and the transition from the vertical position to the horizontal position is represented by the arrow 14 in FIGS. 2A 2B.
Afin de pouvoir assurer la rotation des organes de support, ces derniers peuvent par exemple être équipés de charnières permettant la rotation. Il peut également s'agir de la présence de matériaux déformables pour courber les organes de support.  In order to be able to rotate the support members, the latter can for example be equipped with hinges allowing rotation. It may also be the presence of deformable materials to bend the support members.
Il est possible de faire en sorte que la mise en mouvement des organes de support soit automatisée. Cette automatisation peut se faire de plusieurs manières, possiblement cumulables les unes avec les autres :  It is possible to make the setting in motion of the support members automated. This automation can be done in several ways, possibly cumulative with each other:
- il est tout d'abord possible de placer un actionneur (par exemple un moteur ou tout autre moyen utilisé de manière conventionnel) à l'intérieur d'un mât 8 ou des deux mâts 8. De manière classique, et afin de pouvoir mettre en mouvement les organes de support, il est possible de placer un système de courroies et/ou d'engrenages et/ou de ressorts à l'intérieur des différents profils métalliques du dispositif de support 2 (passage par exemple à l'intérieur du mât 8 et des organes de support, notamment pour protéger le système des projections de peinture). Il est possible que l'activation de l'actionneur soit effectuée par le robot peintre 10 lui-même qui, en venant actionner un interrupteur, par exemple situé sur le cadre 6 à la base des mâts 8, permette le déplacement des organes de support comme expliqué ci-dessus (mouvement possible grâce à un système impliquant plusieurs ressorts). L'activation de l'actionneur peut également être effectuée par le convoyeur (par enclenchement d'une manette, qui peut être située sur la luge, avec un système placé sous la luge, là encore pour protéger le système des projections de peinture) ou encore par un élément externe dédié à cela. it is firstly possible to place an actuator (for example a motor or any other means conventionally used) inside a mast 8 or both masts 8. In a conventional manner, and in order to be able to in movement the support members, it is possible to place a system of belts and / or gears and / or springs inside the various metal profiles of the support device 2 (passage for example inside the mast 8 and support members, in particular to protect the system from splashing paint). he it is possible that the activation of the actuator is carried out by the painter robot itself, which, by actuating a switch, for example located on the frame 6 at the base of the poles 8, allows the displacement of the support members as explained above (possible movement thanks to a system involving several springs). Activation of the actuator can also be performed by the conveyor (by engaging a lever, which can be located on the sled, with a system under the sledge, again to protect the system from splashing paint) or again by an external element dedicated to that.
- Il est également possible que les organes de support soient courbés et/ou allongés afin de permettre le déplacement évoqué ci-dessus. Dans ce cas, ces derniers sont réalisés dans un matériau ou ont une structure permettant leur courbure et/ou leur allongement qui peuvent être mise en œuvre par l'intervention d'un actionneur externe dédié pouvant tirer/pousser les organes de support ou appuyer sur ces derniers.  - It is also possible that the support members are bent and / or elongated to allow the displacement mentioned above. In this case, the latter are made of a material or have a structure allowing their curvature and / or their elongation that can be implemented by the intervention of a dedicated external actuator that can pull / push the support members or press these latter.
- Il peut enfin s'agir d'un actionnement par un système avec une plaque d'appui sur la balancelle. Il s'agit d'un dispositif d'actionnement dans lequel les organes de support comprennent une surface d'appui et des charnières aptes à permettre un basculement des organes de support. Un actionneur externe dédié aux mouvements des organes de support, comme par exemple un vérin, est apte à appuyer sur la surface d'appui des organes de support afin de permettre leur rotation. Le retour en position des organes de support peut être réalisé grâce à un ressort comprimé lorsque l'actionneur appuie sur la surface d'appui.  - It can finally be an actuation by a system with a support plate on the swing. It is an actuating device in which the support members comprise a bearing surface and hinges adapted to allow tilting of the support members. An external actuator dedicated to the movements of the support members, such as a jack, is able to press the bearing surface of the support members to allow their rotation. The return to position of the support members can be achieved by a compressed spring when the actuator presses on the bearing surface.
Les figures 3 et 4 illustrent un second mode de réalisation de l'invention compatible avec celui illustré sur les figures 1 A 1 B et 2A/2B.  Figures 3 and 4 illustrate a second embodiment of the invention compatible with that illustrated in Figures 1 A 1 B and 2A / 2B.
Dans les modes de réalisation présentés ci-dessous, les éléments identiques à ceux du premier mode de réalisation sont indiqués par les mêmes références numériques, les éléments différents sont désignés par des références comportant des chiffres des unités et des dizaines identiques.  In the embodiments presented below, the elements identical to those of the first embodiment are indicated by the same reference numerals, the different elements are designated by references comprising digits of the units and identical tens.
Dans l'exemple illustré aux figures 3 et 4, le dispositif de support 102 comprend un mât 8 et quatre organes de support supportant quatre pièces de carrosserie 4, et les organes de support peuvent se déplacer en translation, ici dans la direction du corps du robot peintre, entre une position rétractée et une position déployée, de préférence dans une direction perpendiculaire à l'axe principal A du mât 8. On peut distinguer d'autres déplacements en translation, par exemple distinguer deux mouvements pouvant être opérés par les organes de support : un mouvement suivant un axe X ou suivant un axe Y, axes représentés sur les figures 3 et 4.  In the example illustrated in Figures 3 and 4, the support device 102 comprises a mast 8 and four support members supporting four body parts 4, and the support members can move in translation, here in the direction of the body of the body. painter robot, between a retracted position and an extended position, preferably in a direction perpendicular to the main axis A of the mast 8. It is possible to distinguish other displacements in translation, for example distinguish two movements that can be operated by the organs of support: a movement along an axis X or along a Y axis, axes shown in Figures 3 and 4.
Cette translation, symbolisée par les flèches 16 sur les figures 3 et 4, permet de dégager certains organes de support, et donc certaines pièces de carrosserie 4 portées par ces organes de support, par rapport au mât 8. Sur la figure 3, on remarque que deux des quatre organes de support (portant la première et la troisième pièce de carrosserie 4 en partant du haut de la figure 3) ont été déplacés et sont désormais plus éloignés, dans une direction parallèle à l'axe principal A ici vers le robot, du mât 8 que les deux autres organes de support. Ce déplacement permet de simplifier la trajectoire du robot peintre 10 mais également d'améliorer le rendement de la chaîne de peinture. En effet, ce dégagement peut permettre de donner plus d'accessibilité aux pièces de carrosserie 4 dégagées pour le robot peintre 10. Cela peut permettre de faciliter la trajectoire que ce dernier va suivre pour peindre les pièces de carrosserie en libérant de la place autour de ces pièces. De plus, il est possible de charger plus de pièces de carrosserie sur un même dispositif de support 102 sans réduire l'accessibilité à ces dernières du fait qu'il est possible d'en dégager une partie qui va être facilement accessible pour le robot peintre 10. De plus, les pièces de carrosserie 4 restent à l'horizontal tout au long du procédé de peinture, notamment lors du pré-séchage, ce qui est idéal pour obtenir un tendu idéal de la peinture sur les pièces de carrosserie. This translation, symbolized by the arrows 16 in FIGS. 3 and 4, makes it possible to to release some support members, and therefore some body parts 4 carried by these support members, relative to the mast 8. In Figure 3, we note that two of the four support members (carrying the first and third body parts 4 from the top of Figure 3) have been moved and are now further away, in a direction parallel to the main axis A here to the robot, the mast 8 than the other two support members. This displacement makes it possible to simplify the trajectory of the painter's robot 10 but also to improve the performance of the paint line. Indeed, this clearance may allow to give more accessibility to the body parts 4 cleared for the robot painter 10. This may facilitate the path that it will follow to paint the body parts by freeing space around these parts. In addition, it is possible to load more body parts on the same support device 102 without reducing accessibility to the latter because it is possible to release a portion that will be easily accessible for the painter robot 10. In addition, the body parts 4 remain horizontal throughout the painting process, especially during the pre-drying, which is ideal to obtain an ideal tension of the paint on the body parts.
Quant au mécanisme d'actionnement permettant la translation des organes de support, il peut s'agir d'actionneur tels que décrits auparavant (actionneur dans un des mâts 8 ou dans les deux, actionneur externe dédié, organes de support pouvant être allongés ...).  As for the actuating mechanism allowing the translation of the support members, it may be an actuator as described previously (actuator in one or both of the masts 8, dedicated external actuator, support members that can be extended. .).
Les figures 5 et 6 illustrent un troisième mode de réalisation de l'invention compatible avec les deux précédents.  Figures 5 and 6 illustrate a third embodiment of the invention compatible with the two previous.
Dans ce dernier, le dispositif de support 202 comprend deux mâts 8 et huit organes de support sur lesquels sont disposés huit pièces de carrosserie 4 (là encore, les nombres de huit organes de support et huit pièces de carrosserie 4 sont donnés à titre d'exemple et peuvent varier).  In the latter, the support device 202 comprises two masts 8 and eight support members on which are arranged eight bodywork parts 4 (again, the numbers of eight support members and eight bodywork parts 4 are given as example and may vary).
Les mâts 8 sont montés pivotant sur le cadre 6 afin de pouvoir pivoter autour de leurs axes principaux respectifs (équivalents à l'axe principal A illustré sur les figures 1 et 2). Cela permet de simplifier la trajectoire du robot peintre 10 et d'augmenter le rendement de la chaîne de peinture en chargeant plus de pièces de carrosserie 4 sur chaque dispositif de support, par exemple sur quatre faces comme illustré sur les figures 5 et 6, mais également en ménageant plus d'espaces entre les différentes pièces de carrosserie 4 d'une même face du dispositif de support 202.  The masts 8 are pivotally mounted on the frame 6 so as to be pivotable about their respective main axes (equivalent to the main axis A illustrated in Figures 1 and 2). This makes it possible to simplify the trajectory of the painter's robot 10 and to increase the efficiency of the paint line by loading more body parts 4 onto each support device, for example on four faces as illustrated in FIGS. 5 and 6, but also by providing more space between the different body parts 4 of the same face of the support device 202.
Dès lors, le robot peintre 10 dispose d'un espace lui permettant d'avoir facilement accès aux différentes faces des pièces de carrosserie 4. Il est alors possible, après que les pièces de carrosserie 4 d'une face du dispositif de support 202 aient été peintes par le robot peintre 10, dé faire pivoter les mâts 8 de 90° afin de placer face au robot peintre 10 de nouvelles pièces de carrosserie 4 non peintes pour que ces dernières le soient. Cela est illustré aux figures 5 et 6. Sur la figure 5, les pièces de carrosserie 4 présentes sur la face du dispositif de peinture 202 la plus proche du robot peinture 10 sont peintes puis le dispositif de support 202 peut pivoter, comme illustré par la flèche 18 sur les figures 5 et 6, et des pièces de carrosserie 4 d'une autre face présentes sur le dispositif de support 202 afin que ces dernières puissent être peintes par le robot peintre 10. Therefore, the painter robot 10 has a space allowing it to have easy access to the different faces of the body parts 4. It is then possible, after the body parts 4 of a face of the support device 202 have been painted by the painter robot 10, to rotate the mast 8 90 ° to place facing the robot painter 10 new body parts 4 unpainted for them to be. This is illustrated in FIGS. 5 and 6. In FIG. 5, the bodywork parts 4 present on the face of the painting device 202 closest to the painting robot 10 are painted, then the support device 202 can pivot, as illustrated by FIG. arrow 18 in FIGS. 5 and 6, and body parts 4 of another face present on the support device 202 so that the latter can be painted by the painter robot 10.
La mobilité des mâts 8 peut être réalisée par l'intermédiaire des mécanismes d'actionnement décrits ci-dessus, à savoir : un actionneur présent dans les mâts 8 avec un actionnement par le robot peintre ou encore par le convoyeur.  The mobility of the masts 8 can be achieved by means of the actuating mechanisms described above, namely: an actuator present in the masts 8 with an actuation by the painter robot or by the conveyor.
II est par exemple possible d'envisager que les organes de support portés par des faces opposées se rapprochent du mât. Ceci est avantageux au moment de passer d'une zone de peinture à une autre, ces passages étant souvent étroits pour éviter la pollution d'une zone de peinture par la zone adjacente. Ce rapprochement peut aussi être avantageux dans les zones de séchages pour limiter le volume à chauffer et diminuer la consommation d'énergie.  It is for example possible to envisage that the support members carried by opposite faces are close to the mast. This is advantageous when moving from one paint zone to another, these passages being often narrow to avoid pollution of a paint zone by the adjacent area. This approximation may also be advantageous in the drying zones to limit the volume to be heated and to reduce the energy consumption.
Les figures 7 et 8 illustrent un quatrième mode de réalisation de l'invention compatible avec les trois précédents.  Figures 7 and 8 illustrate a fourth embodiment of the invention compatible with the previous three.
Dans ce dernier, le dispositif de support 302 comprend deux mâts 8 et quatre pièces de carrosserie 4 supportées par quatre organes de support. Encore une fois, le nombres de mâts 8 et d'organes de support sont variables. Chaque mât 8 porte une partie des organes de support.  In the latter, the support device 302 comprises two masts 8 and four body parts 4 supported by four support members. Again, the number of poles 8 and support members are variable. Each mast 8 carries a portion of the support members.
Dans cet exemple, les mâts 8 sont mobiles en translation de manière à pouvoir s'éloigner l'un de l'autre (déplacement pouvant s'effectuer dans des directions opposées l'un à l'autre). Il est également possible qu'un seul des deux mâts soit mobile en translation et l'autre fixe. Cette capacité de mouvement est illustrée sur les figures 7 et 8 par les flèches 20. Sur la figure 7, le dispositif de support 302 est placé à proximité d'un robot peintre 10 au niveau d'un poste de peinture. Dès lors, les deux mâts 8 ont la capacité de se déplacer afin de pouvoir s'éloigner l'un de l'autre (par exemple par des déplacements selon une même direction mais dans des sens opposés).  In this example, the masts 8 are movable in translation so as to be able to move away from each other (displacement can be effected in opposite directions to each other). It is also possible that only one of the two masts is mobile in translation and the other fixed. This movement capacity is illustrated in FIGS. 7 and 8 by the arrows 20. In FIG. 7, the support device 302 is placed near a painter's robot 10 at a paint station. Therefore, the two masts 8 have the ability to move in order to move away from each other (for example by moving in the same direction but in opposite directions).
Cet éloignement est illustré à la figure 8. On observe que les deux mâts 8, en s'éloignant l'un de l'autre, permettent un éloignement des organes de support portés par des mâts 8 différents. Cela permet de simplifier la tâche du robot peintre 10 en libérant de l'espace autour des pièces de carrosserie 4 à peindre (simplification de la trajectoire du robot peintre 10, potentielle diminution du temps de peinture). De plus, cela permet de charger plus de pièces de carrosserie 4 sur un même dispositif de support 2 et donc d'améliorer le rendement de la chaîne de peinture sans gêner le robot peintre 10.  This distance is illustrated in Figure 8. It is observed that the two masts 8, moving away from each other, allow a distance of support members carried by different masts 8. This makes it possible to simplify the task of the painter robot 10 by freeing up space around the bodywork parts 4 to be painted (simplification of the trajectory of the painter's robot 10, potentially reducing the painting time). In addition, this makes it possible to load more bodywork parts 4 on the same support device 2 and thus to improve the performance of the paint line without interfering with the painter's robot 10.
Le déplacement des mâts 8 peut être effectué dans une direction perpendiculaire aux axes principaux A et A' des mâts 8, de préférence dans des sens opposés l'un à l'autre afin d'assurer un éloignement important des organes de support sans pour autant avoir à beaucoup déplacer les mâts 8. The displacement of the masts 8 can be carried out in a direction perpendicular to the main axes A and A 'of the masts 8, preferably in opposite directions to one another in order to ensure a large distance of the support members without having to move the masts 8 a great deal.
Il est possible de faire en sorte que, comme cela est représenté sur les figures 7 et 8, deux organes de support disposés côte à côte soient portés par des mâts 8 différents. It is possible to ensure that, as shown in Figures 7 and 8, two support members arranged side by side are carried by different masts 8.
En effet, cela permet d'assurer la présence d'un espace substantiel entre les organes de support lorsque les mâts 8 sont éloignés l'un de l'autre car deux organes de support disposés côte à côte seront éloignés l'un de l'autre. Indeed, this makes it possible to ensure the presence of a substantial space between the support members when the masts 8 are distant from each other because two support members arranged side by side will be distant one of the other.
Quant au dispositif d'actionnement d'un tel dispositif de support 302, ce dernier peut être effectué par les exemples décrits plus haut et compatibles avec ce mode de réalisation. Il est aussi possible de monter les deux mâts 8 sur des glissières afin de leur permettre de se déplacer par translation.  As for the device for actuating such a support device 302, the latter can be performed by the examples described above and compatible with this embodiment. It is also possible to mount the two poles 8 on slides to allow them to move by translation.
Dans un exemple non représenté sur les figures, il est possible que les mâts 8 soient mobiles dans une direction parallèle à leurs axes principaux A et A' respectifs, en étant par exemple télescopiques. Il est tout à fait possible que, dans ce cas de figure, le dispositif de support 302 ne comprenne qu'un seul mât 8. Ainsi, le dispositif de peinture In an example not shown in the figures, it is possible for the poles 8 to be movable in a direction parallel to their respective main axes A and A ', for example being telescopic. It is quite possible that, in this case, the support device 302 comprises only one mast 8. Thus, the painting device
302 est disposé devant un robot peintre 10 au niveau d'un poste de peinture. Un déploiement télescopique du ou des mâts 8 permet d'augmenter l'espace entre les différents organes de support donc entre les différentes pièces de carrosserie 4. Un tel déploiement peut par exemple être effectué par un actionneur externe, par exemple un ou plusieurs bras robotisés fixés au plafond de la chaîne de peinture et aptes à tirer sur le ou les mâts 8 afin de les déployer. 302 is disposed in front of a paint robot 10 at a paint station. A telescopic deployment of the mast or masts 8 makes it possible to increase the space between the various support members and thus between the different bodywork parts 4. Such a deployment may for example be carried out by an external actuator, for example one or more robotic arms. attached to the ceiling of the paint line and able to pull the mast or masts 8 to deploy them.
Lors du procédé de peinture utilisant un dispositif de support 2, les étapes suivantes sont exécutées au moins une fois, classiquement plusieurs fois (plusieurs couches de peinture, par exemple, base, peinture puis vernis, sont appliquées successivement sur les pièces de carrosserie 4) :  During the painting process using a support device 2, the following steps are performed at least once, typically several times (several layers of paint, for example, base, paint and varnish, are applied successively to the body parts 4) :
- on déplace le dispositif de support 2 afin de le placer devant un robot peintre 10. the support device 2 is moved in order to place it in front of a painter robot 10.
- on fait pivoter les organes de support d'une première position vers une seconde position. La première position est préférentiellement une position horizontale (voire même la position dans laquelle les pièces de carrosserie 4 seront placées une fois montées sur un véhicule) et la seconde position une position verticale. Comme expliqué auparavant, il est possible de permettre aux organes de support d'occuper plusieurs positions entre deux positions extrêmes. the support members are pivoted from a first position to a second position. The first position is preferably a horizontal position (or even the position in which the body parts 4 will be placed once mounted on a vehicle) and the second position a vertical position. As explained above, it is possible to allow the support members to occupy several positions between two extreme positions.
- on peint les pièces de carrosserie 4 immobiles présentes sur les organes de support.  the non-stationary bodywork parts 4 present on the support members are painted.
- on fait pivoter les organes de support de la seconde position vers la première position. Dans le cas d'un retour des pièces de carrosserie 4 dans une position horizontale, cela permet d'améliorer la mise en tension de la peinture sur les pièces de carrosserie 4. the support members are pivoted from the second position to the first position. In the case of a return of the body parts 4 in a position horizontal, this improves the tensioning of the paint on the body parts 4.
