Description
Dispositif de suspension d'outils à commande manuelle dans une chaîne d'assemblaae
La présente invention concerne le domaine des chaînes d'assemblage, en particulier de véhicules automobiles. Dans de telles chaînes, on utilise de nombreux outils à commande manuelle alimentés en électricité et/ou en fluide. Un exemple d'un tel outil est un poste à pince de soudage, qui comporte, en plus de la pince de soudage elle-même, divers autres composants tels qu'une commande programmable de soudage, un transformateur de soudage, un contacteur statique à thyristors, etc.Manually operated tool suspension device in an assembly line
The present invention relates to the field of assembly lines, in particular of motor vehicles. In such chains, numerous manually operated tools are used supplied with electricity and / or fluid. An example of such a tool is a welding clamp station, which comprises, in addition to the welding clamp itself, various other components such as a programmable welding control, a welding transformer, a solid state contactor. thyristors, etc.
Jusqu'à présent, pour autoriser les déplacements de l'outil nécessaires au processus de fabrication, il était usuel de suspendre les outils et leurs accessoires à des rails de roulement, lesquels sont fixés à la charpente de l'usine d'assemblage par des sous-charpentes démontables. Une telle installation nécessite un accrochage au sol de l'outil, au moyen d'un pied d'accrochage, et un système de détection associé.Until now, to allow the tool movements necessary for the manufacturing process, it was customary to suspend the tools and their accessories on running rails, which are fixed to the frame of the assembly plant by removable sub-frames. Such an installation requires a hanging on the ground of the tool, by means of a hanging foot, and an associated detection system.
L'ensemble de la sous-charpente portant les rails de roulement doit être construit en fonction de la chaîne d'assemblage à implanter, de sorte qu'un démontage est nécessaire pour l'implantation d'une nouvelle chaîne avec son système spécifique de rails. Ces opérations sont longues et coûteuses, la structure constituée par la souscharpente et les rails de roulement étant elle-même onéreuse de conception, de fabrication et de montage.The entire underframe carrying the running rails must be built according to the assembly line to be installed, so that disassembly is necessary for the installation of a new chain with its specific rail system . These operations are long and costly, the structure constituted by the underframe and the running rails being itself expensive in design, manufacture and assembly.
Une modification de la chaîne d'assemblage est extrêmement difficile et coûteuse.Modifying the assembly line is extremely difficult and costly.
Un autre inconvénient du système connu qui vient d'être décrit réside en une grande difficulté à réutiliser dans une nouvelle chaîne le matériel ainsi implanté du fait de la définition spécifique du poste de travail suspendu.Another disadvantage of the known system which has just been described resides in a great difficulty in reusing in a new chain the material thus implanted because of the specific definition of the suspended work station.
Les réparations et les échanges de composants sont également délicats du fait de la suspension d'une unité de travail qui doit de ce fait être la plus intégrée possible.Repairs and exchange of components are also tricky due to the suspension of a work unit which must therefore be as integrated as possible.
La présente invention vise à supprimer ces inconvénients des systèmes connus.The present invention aims to eliminate these drawbacks from known systems.
A cet effet, l'invention a pour objet un dispositif de support d'un poste de travail manuel suspendu dans une chaîne de fabrication/assemblage, caractérisé en ce qu'il est constitué par une potence munie d'au moins un organe d'accrochage d'un outil et de moyens d'équilibrage de l'outil en position verticale, ladite potence étant solidaire d'un fût fixé à la charpente par l'intermédiaire d'une platine.To this end, the subject of the invention is a device for supporting a manual work station suspended in a production / assembly line, characterized in that it consists of a bracket provided with at least one organ for attachment of a tool and means for balancing the tool in a vertical position, said bracket being secured to a barrel fixed to the frame by means of a plate.
Le dispositif selon l'invention permet d'obtenir une structure de support d'outillages lourds qui est d'implantation souple et économique sous forme d'une chaîne de montage/assemblage, en ne nécessitant pratiquement pas de travaux d'infrastructure sur le bâtiment. Les dispositifs selon l'invention peuvent être réutilisés, éventuellement après reconditionnement. The device according to the invention makes it possible to obtain a support structure for heavy tools which is flexible and economical to install in the form of an assembly / assembly line, practically requiring no infrastructure work on the building. . The devices according to the invention can be reused, possibly after repackaging.
En outre, un tel dispositif permet avantageusement de prévoir une structure de supports d'outillage dans des sites où la surface au sol est réduite.In addition, such a device advantageously makes it possible to provide a structure of tool supports in sites where the ground surface is reduced.
Divers types d'implantation peuvent être envisagés.Various types of implantation can be envisaged.
Selon une forme de réalisation, la potence est fixe par rapport au fût.According to one embodiment, the stem is fixed relative to the barrel.
Dans une variante, la potence est montée rotative autour de l'axe du fût. I1 est encore possible de prévoir en outre que l'organe d'accrochage est mobile en translation le long de la potence.Alternatively, the stem is rotatably mounted around the axis of the barrel. I1 is also possible to further provide that the attachment member is movable in translation along the bracket.
L'invention sera bien comprise à la lecture de la description suivante, en référence au dessin annexé dans lequel la figure unique est une vue schématique en élévation latérale d'un dispositif de support selon un exemple de réalisation de l'invention et équipé d'une pince de soudage.The invention will be clearly understood on reading the following description, with reference to the accompanying drawing in which the single figure is a schematic side elevation view of a support device according to an embodiment of the invention and equipped with welding tongs.
Le dispositif de support selon l'invention, tel que représenté schématiquement dans la figure unique, comprend une potence 1 solidaire d'un fût 2 fixé sur la charpente.The support device according to the invention, as shown diagrammatically in the single figure, comprises a bracket 1 secured to a barrel 2 fixed to the frame.
Un outil, tel qu'une pince de soudage 3, est relié à la potence 1, par exemple par un équilibreur 4 ou similaire, de manière à être mobile verticalement.A tool, such as a welding clamp 3, is connected to the bracket 1, for example by a balancer 4 or the like, so as to be movable vertically.
Dans une forme de réalisation simple, l'outil 3 est fixe en translation par rapport à la potence 1 et la potence 1 est fixe par rapport au fût 2.In a simple embodiment, the tool 3 is fixed in translation relative to the stem 1 and the stem 1 is fixed relative to the barrel 2.
I1 est également possible d'envisager une variante dans laquelle la potence 1 peut pivoter autour de l'axe du fût 2. I1 suffit à cet effet que le fût 2 soit monté pivotant autour de son axe, au moyen d'un palier, par rapport à une platine 5 de liaison à la charpente. Ce pivotement pourra être limité par des butées, par exemple des butées en caoutchouc ou des amortisseurs hydrauliques d'inertie, disposées en correspondance sur le fût 2 et/ou sur son axe de rotation (non représenté). On peut prévoir des butées réglables ou déplaçables pour ajuster le débattement angulaire à l'application envisagée et à l'ergonomie de l'outil. I1 is also possible to envisage a variant in which the stem 1 can pivot around the axis of the barrel 2. I1 suffices for this purpose that the barrel 2 is mounted pivoting about its axis, by means of a bearing, by compared to a plate 5 for connection to the frame. This pivoting may be limited by stops, for example rubber stops or hydraulic inertia dampers, arranged in correspondence on the barrel 2 and / or on its axis of rotation (not shown). One can provide adjustable or movable stops to adjust the angular travel to the intended application and the ergonomics of the tool.
Une variante plus sophistiquée peut prévoir une possibilité de coulissement horizontal de l'outil 3 par déplacement linéaire de sa fixation 6 à la potence 1.A more sophisticated variant can provide a possibility of horizontal sliding of the tool 3 by linear displacement of its attachment 6 to the bracket 1.
La platine 5 peut revêtir diverses formes de réalisation.The plate 5 can take various embodiments.
Dans une forme de réalisation, la platine 5 est fixée à la charpente par des moyens d'ancrage mécaniques tels que des crapauds ou des boulons.In one embodiment, the plate 5 is fixed to the frame by mechanical anchoring means such as toads or bolts.
Selon une variante de réalisation du dispositif de support et afin d'améliorer l'ergonomie pour des postes difficiles, on peut ajouter en bout de potence 1, un bras articulé 10, le long duquel le système d'accrochage et d'équilibrage 4, 6 peut coulisser.According to an alternative embodiment of the support device and in order to improve ergonomics for difficult positions, one can add at the end of the stem 1, an articulated arm 10, along which the attachment and balancing system 4, 6 can slide.
Dans tous les cas, l'équilibrage de l'outil 3 peut être réalisé au moyen d'un équilibreur connu disponible dans le commerce ou par un système à câble, poulies et contrepoids, le contrepoids coulissant dans le fût 2, et réglable par addition ou suppression de masses.In all cases, the balancing of the tool 3 can be achieved by means of a known balancer available commercially or by a cable system, pulleys and counterweights, the counterweight sliding in the barrel 2, and adjustable by addition. or removal of masses.
Le dispositif selon l'invention offre l'avantage de permettre d'intégrer divers composants et accessoires sur le fût 2 et/ou sur la potence 1. C'est ainsi que, pour une pince de soudage 3, le transformateur 8 est implanté dans un berceau 8' sur le fût 2 et l'armoire électrique, le panneau fluide (refroidissement, surpresseur 9, vanne proportionnelle, distributeur, etc.) et la commande programmable sont fixés sur le fût 2. Le choix des composants et leur remplacement sont ainsi grandement facilités. Mais, en outre, on peut prévoir de monter sur le même support deux outils utilisés en alternance et qui utiliseront, au moins en partie, les mêmes accessoires.The device according to the invention offers the advantage of making it possible to integrate various components and accessories on the barrel 2 and / or on the bracket 1. This is how, for a welding clamp 3, the transformer 8 is installed in an 8 'cradle on the barrel 2 and the electrical cabinet, the fluid panel (cooling, booster 9, proportional valve, distributor, etc.) and the programmable control are fixed on the barrel 2. The choice of components and their replacement are thus greatly facilitated. But, in addition, provision can be made to mount on the same support two tools used alternately and which will use, at least in part, the same accessories.
Le dispositif selon l'invention peut être équipé de capteurs ou de détecteurs pour le contrôle des positions diverses que peut occuper l'outil, selon les divers modes de réalisation choisis. The device according to the invention can be equipped with sensors or detectors for controlling the various positions that the tool can occupy, according to the various embodiments chosen.
