Description

Luge pour transporter des éléments à assembler et procédé d'assemblage utilisant une telle luge Luge for transporting elements to be assembled and assembly method using such sledge
La présente invention concerne une luge pour transporter des éléments à assembler en particulier les éléments du soubassement d'un véhicule automobile, destinés à être soudés ensemble.The present invention relates to a sled for transporting elements to be assembled, in particular the elements of the underbody of a motor vehicle, intended to be welded together.
L'invention concerne également un procédé d'assemblage de la caisse de véhicules automobiles, utilisant une luge selon l'invention.The invention also relates to a method of assembling the body of motor vehicles, using a sledge according to the invention.
Cette luge comprend de façon connue, (voir figure 1) deux poutres longitudinales 1 , 2 et plusieurs traverses 3, 4, 5, 6, 7 fixées à ces deux poutres.This sledge comprises in known manner, (see Figure 1) two longitudinal beams 1, 2 and several sleepers 3, 4, 5, 6, 7 attached to these two beams.
Chaque traverse 3, 4, 5, 6, 7 comporte deux points d'appui 8, 9 pour supporter l'un des éléments 10, 1 1 , 12 (voir figure 3) du soubassement à assembler.Each crossbar 3, 4, 5, 6, 7 has two support points 8, 9 to support one of the elements 10, 1 1, 12 (see Figure 3) of the base to be assembled.
Ainsi, comme montré par la figure 3, chacun des éléments 10, 1 1 , 12 est supporté par deux traverses fixes espacées, c'est-à-dire par quatre points d'appui.Thus, as shown in Figure 3, each of the elements 10, 1 1, 12 is supported by two fixed crosspieces spaced apart, that is to say by four points of support.
Etant donné que la forme et les dimensions des éléments du soubassement varient d'une caisse à l'autre, chacune des luges est spécifique pour une caisse de véhicule.Since the shape and dimensions of the underbody elements vary from one box to another, each of the sleds is specific for a vehicle body.
Il est donc nécessaire de mettre en œuvre un nombre de luges tels que celle montrée sur la figure 1 égal au nombre de soubassements différents à assembler.It is therefore necessary to implement a number of sleds such as that shown in Figure 1 equal to the number of different substructures to assemble.
Lorsque les éléments 10, 1 1 , 12 du soubassement sont soudés ensemble, l'ensemble du soubassement est d'un seul tenant, et peut ainsi être supporté par une luge telle que représentée sur les figures 2 et 4, ne comportant que deux traverses fixes définissant quatre points d'appui.When the elements 10, 1 1, 12 of the base are welded together, the entire base is in one piece, and can thus be supported by a sled as shown in Figures 2 and 4, having only two sleepers fixed positions defining four points of support.
Cette luge peut alors servir pour transporter le soubassement vers d'autres postes d'assemblage de la caisse dans lesquels on ajoute au soubassement les côtés de caisse, des traverses, le pavillon, etc .. par soudage, vissage ou collage.This sledge can then be used to transport the base to other assembly stations of the body in which the body sides, sleepers, roof, etc. are added to the underbody by welding, screwing or gluing.
Cette luge ne comportant que deux traverses est également spécifique pour chaque soubassement d'un type donné de véhicule.This sled comprising only two sleepers is also specific for each base of a given type of vehicle.
Ainsi pour pouvoir transporter sur une ligne d'assemblage des éléments de soubassement, des soubassements soudés et des caisses de véhicules différents, il est nécessaire d'utiliser un grand nombre de luges différentes.Thus to be able to transport on an assembly line underbody elements, welded bases and crates of different vehicles, it is necessary to use a large number of different sleds.
Le but de la présente invention est de remédier à cet inconvénient.The object of the present invention is to overcome this disadvantage.
Ce but est atteint selon l'invention, grâce à une luge pour transporter des éléments à assembler, en particulier, les éléments du soubassement d'un véhicule automobile, destinés à être soudés ensemble, cette luge comportant deux poutres longitudinales et plusieurs traverses fixées à ces deux poutres, chaque traverse comportant au moins deux points d'appui pour supporter l'un des éléments à assembler, caractérisée en ce que la luge comporte en outre, une ou plusieurs traverses indépendantes les unes des autres et fixées de façon amovible aux deux poutres longitudinales de façon qu'elles puissent être retirées après assemblage des éléments.This object is achieved according to the invention, thanks to a sledge for transporting elements to be assembled, in particular, the elements of the underbody of a motor vehicle, intended to be welded together, this sledge comprising two longitudinal beams and several crosspieces attached to these two beams, each crossmember having at least two support points for supporting one of the elements to be assembled, characterized in that the sled further comprises, one or more sleepers independent of each other and removably attached to both longitudinal beams so that they can be removed after assembly of the elements.
Grâce aux traverses amovibles, la luge peut être adaptée pour transporter des éléments de soubassement pour des caisses différentes, jusqu'au poste de soudage, après quoi ces traverses amovibles peuvent être retirées.Thanks to the removable sleepers, the sled can be adapted to carry underbody elements for different crates, to the welding station, after which these removable crosspieces can be removed.
Dans un mode de réalisation, la luge comprend au moins deux traverses fixes comportant chacune deux points d'appui, la position de ces traverses et celle des points d'appui étant telle que la luge puisse supporter le soubassement soudé d'un véhicule automobile, après retrait des traverses amovibles.In one embodiment, the sled comprises at least two fixed crosspieces each having two support points, the position of these crosspieces and that of the support points being such that the sled can support the welded underside of a motor vehicle, after removal of the removable sleepers.
L'invention concerne également un procédé d'assemblage de la caisse de véhicules automobiles utilisant une luge telle que définie ci-dessus, cette luge étant utilisable pour transporter les éléments du soubassement avant et après le soudage de ces éléments et pour transporter le soubassement soudé vers d'autres postes d'assemblage de la caisse du véhicule, caractérisé par les étapes suivantes :The invention also relates to a method of assembling the body of motor vehicles using a sledge as defined above, this sledge being used to transport the elements of the underbody before and after welding of these elements and to transport the welded underbody to other assembly stations of the vehicle body, characterized by the following steps:
- on transporte les éléments du soubassement vers le poste de soudage au moyen d'une luge comportant des traverses fixes et des traverses amovibles indépendantes les unes des autres dont le nombre et la position sont prédéterminés en fonction du soubassement de la caisse du véhicule,the elements of the underbody are transported to the welding station by means of a sledge comprising fixed sleepers and removable sleepers independent of one another, the number and position of which are predetermined according to the underbody of the vehicle body,
- après soudage des éléments du soubassement, on retire les traverses amovibles, et, - on déplace la luge portant le soubassement ainsi soudé vers d'autres postes d'assemblage de la caisse du véhicule.after welding of the elements of the base, the removable crosspieces are removed, and, the sled carrying the welded base is moved to other assembly stations of the vehicle body.
Dans un mode de réalisation, la luge comporte deux traverses fixes comportant chacune deux points d'appui situés chacun près de l'une des deux extrémités opposées de la traverse, de façon à définir quatre points d'appui suffisants pour supporter un soubassement dont les éléments ont été soudés ensemble, et des traverses amovibles comportant chacune deux points d'appui, de façon que les éléments du soubassement soient supportés chacun, avant leur soudage, par quatre points d'appui.In one embodiment, the sled comprises two fixed crosspieces each having two support points each located near one of the two opposite ends of the cross-member, so as to define four support points sufficient to support a base of which the elements were welded together, and removable cross members each having two points of support, so that the elements of the base are each supported before welding, by four points of support.
Dans la plupart des cas, la luge est adaptée pour transporter un soubassement constitué de trois éléments, à savoir l'unit avant, l'unit central et l'unit arrière et comprend à cet effet deux traverses fixes et trois traverses amovibles.In most cases, the sled is adapted to carry a base consisting of three elements, namely the front unit, the central unit and the rear unit and comprises for this purpose two fixed crosspieces and three removable crosspieces.
Dans ce cas, de préférence, l'une des traverses amovibles est située entre les deux traverses fixes et les deux autres traverses amovibles sont situées à l'extérieur des deux traverses fixes.In this case, preferably, one of the removable cross members is located between the two fixed crosspieces and the two other removable crosspieces are located outside the two fixed crosspieces.
D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.Other features and advantages of the invention will become apparent throughout the description below.
Aux dessins annexés, donnés à titre d'exemples, non limitatifs : la figure 5 est une vue schématique en plan d'une luge selon l'invention comportant deux traverses fixes pouvant être utilisée pour transporter des caisses de différents véhicules automobiles, la figure 6 représente un jeu de traverses amovibles pouvant être placées sur la luge de la figure 5 pour transporter les éléments d'un soubassement de caisse, la figure 7 est une vue analogue à la figure 5, les trois traverses amovibles de la figure 6 ayant été ajoutées à la luge selon la figure 5, la figure 8 est une vue latérale schématique de la luge selon la figure 7, supportant les trois éléments d'un soubassement de caisse de véhicule automobile.In the accompanying drawings, given by way of nonlimiting example: FIG. 5 is a diagrammatic plan view of a sledge according to the invention comprising two fixed crosspieces that can be used to transport boxes of various motor vehicles, FIG. represents a set of removable sleepers that can be placed on the sled of FIG. 5 to transport the elements of a bedrock, FIG. 7 is a view similar to FIG. 5, the three removable sleepers of FIG. 6 having been added. Figure 8 is a schematic side view of the sled according to Figure 7, supporting the three elements of a motor vehicle body underbody.
La figure 9 est une vue en perspective d'une luge selon l'invention. La figure 5 représente une luge comportant deux longerons 1 , 2 et deux traverses fixes 4, 6 définissant ensemble quatre points d'appui 13, 14, 15, 16 pour supporter une caisse d'un véhicule automobile.Figure 9 is a perspective view of a sledge according to the invention. Figure 5 shows a sledge comprising two longitudinal members 1, 2 and two fixed cross members 4, 6 together defining four bearing points 13, 14, 15, 16 to support a box of a motor vehicle.
Cette luge est utilisable pour supporter des caisses différentes, c'est-à-dire destinées à des véhicules différents. En effet les appuis 13, 14, 15 16 sont les mêmes pour tous les véhicules ou présentant une petite mise en opération de l'appui (ex : appui sur une glissière), les pièces de soubassement ayant des formes identiques pour les appuis pour tous les véhicules.This sled can be used to support different boxes, that is to say intended for different vehicles. Indeed the supports 13, 14, 15 16 are the same for all vehicles or having a small operation of the support (eg: support on a slide), the base pieces having identical shapes for support for all the vehicles.
Pour pouvoir transporter les trois units 10, 11, 12 d'un soubassement de caisse, comme indiqué sur la figure 8, on ajoute à la luge représentée sur la figure 5, les trois traverses spécifiques 17, 18, 19 représentées sur la figure 6 pour obtenir la luge représentée sur la figure 7.In order to be able to transport the three units 10, 11, 12 of a bedrock as shown in FIG. 8, the three specific sleepers 17, 18, 19 shown in FIG. 6 are added to the sled shown in FIG. to obtain the sledge shown in Figure 7.
On obtient ainsi sur la luge suffisamment de points d'appui pour supporter les trois units 10, 11, 12, comme montré par la figure 8.This gives the sled enough support points to support the three units 10, 11, 12, as shown in Figure 8.
Dans l'exemple représenté sur les figures 7 et 8, la luge comprend deux traverses fixes 4, 6 et trois traverses amovibles 17, 18, 19 indépendantes les unes des autres.In the example shown in Figures 7 and 8, the sled comprises two fixed crosspieces 4, 6 and three removable cross members 17, 18, 19 independent of each other.
L'une 18 des traverses est située entre les deux traverses fixes 4, 6 et les deux autres traverses 17, 19 sont situées à l'extérieur des deux traverses fixes 4, 6.One 18 of the crosspieces is located between the two fixed crosspieces 4, 6 and the other two crosspieces 17, 19 are located outside the two fixed crosspieces 4, 6.
Les trois traverses amovibles 17, 18, 19 peuvent être retirées de façon indépendante, une fois que les trois units 10, 11, 12 ont été soudés ensemble.The three removable struts 17, 18, 19 can be removed independently, once the three units 10, 11, 12 have been welded together.
Lorsqu'on veut transporter les units du soubassement d'une autre caisse, on utilise la même luge que celle représentée sur la figure 5 et on place sur celle-ci des traverses 17, 18, 19 indépendantes les unes des autres et spécifiques à la nouvelle caisse pour obtenir suffisamment de points d'appui pour supporter les units de la nouvelle caisse.When it is desired to transport the units of the underbody of another box, the same sled is used as that shown in FIG. 5 and there are placed thereon crosspieces 17, 18, 19 that are independent of one another and specific to the new crate to get enough points of support to support the units of the new crate.
Une fois les trois units soudés, les traverses 17, 18, 19 peuvent être retirées de façon indépendante pour la suite des opérations.Once the three units are welded, the cross members 17, 18, 19 can be removed independently for further operations.
La figure 9 est une vue en perspective d'un exemple de luge selon l'invention. Celle-ci comprend deux poutres longitudinales 1 , 2 des traverses fixes 3, 4, 5, 6, 7 et des traverses amovibles 8 et 9a, 9b, cette dernière étant constituée par deux éléments distincts.Figure 9 is a perspective view of an example of sled according to the invention. This comprises two longitudinal beams 1, 2 of the fixed crosspieces 3, 4, 5, 6, 7 and removable cross members 8 and 9a, 9b, the latter being constituted by two distinct elements.
Les principaux avantages de la luge que l'on vient de décrire sont les suivants : la même luge peut servir à transporter les units du soubassement de la caisse de plusieurs véhicules, ce qui permet de réduire les coûts par rapport à l'art antérieur utilisant des luges différentes pour les différentes caisses, les traverses amovibles sont complètement indépendantes les unes des autres, ce qui permet une grande modularité et une très grande souplesse dans la manipulation et le choix des traverses amovibles, il suffit, en effet, d'ajouter à une luge commune une ou plusieurs traverses spécifiques dont le nombre, la position sur la luge et les points d'appui sont prédéterminés en fonction du soubassement de la caisse du véhicule.The main advantages of the sled that have just been described are the following: the same sled can be used to transport the units of the underbody of the body of several vehicles, which makes it possible to reduce the costs compared to the prior art using different sleds for the different boxes, the removable sleepers are completely independent of each other, which allows a great modularity and a great flexibility in the handling and the choice of removable sleepers, it suffices, indeed, to add to a common sledge one or more specific sleepers, the number of which, the position on the sledge and the support points are predetermined according to the underbody of the vehicle body.
A titre d'exemple, dans le cas d'une ligne de fabrication comportant 120 postes de travail, la solution actuelle utilise 150 luges par type de caisses.For example, in the case of a production line comprising 120 workstations, the current solution uses 150 sleds per type of crates.
Par conséquent pour deux caisses différentes, 300 luges sont nécessaires avec un magasin de luge.Therefore for two different crates, 300 toboggans are needed with a toboggan shop.
Dans le cas de l'invention, pour deux caisses différentes, 150 luges et 60 jeux de traverses amovibles suffisent. En effet, les éléments de soubassement 10, 1 1 , 12, voir figure 8, sont soudés seulement sur environ 25 postes, les appuis des traverses amovibles 17, 18, 19, voir figure 6, ne sont nécessaires que sur les 25 postes. Sur le reste des postes les quatre appuis 13, 14, 15, 16, voir figure 5, suffisent.In the case of the invention, for two different boxes, 150 sleds and 60 sets of removable sleepers are sufficient. Indeed, the base members 10, 1 1, 12, see Figure 8, are welded only about 25 stations, the supports of the removable cross members 17, 18, 19, see Figure 6, are required only on 25 stations. On the rest of the positions the four supports 13, 14, 15, 16, see Figure 5, suffice.
Bien entendu, l'invention n'est pas limitée au transport d'units du soubassement de caisse de véhicules automobiles.Of course, the invention is not limited to the transport of units of the underbody of motor vehicles.
En effet, la luge selon l'invention peut également servir au transport de pièces destinées à être assemblées dans d'autres domaines d'application.Indeed, the sled according to the invention can also be used for transporting parts intended to be assembled in other fields of application.
Par ailleurs, les traverses amovibles peuvent être reliées aux poutres longitudinales de la luge par tout type de moyens de fixation, tant qu'ils permettent une installation sûre d'un point de vue sécurité et une désinstallation simple et indépendante des traverses amovibles. Furthermore, the removable sleepers can be connected to the longitudinal beams of the sled by any type of fastening means, as long as they allow a safe installation from a security point of view and a simple and independent removal of the removable sleepers.
