Abstract

The support system to manufacture metal reinforcements for concrete formed of longitudinal continuous bars assembled by transverse frames, comprises first and second parallel support arms placed in a same horizontal plane, and a carrying structure. The first and second parallel support arms are mounted on the carrying structure. The first parallel support arms (3) are associated with controllable units (5, 6, 7, 8), which allow simultaneous vertical movement to constitute a first vertically moveable horizontal support plane for the longitudinal continuous bars. The support system to manufacture metal reinforcements for concrete formed of longitudinal continuous bars assembled by transverse frames, comprises first and second parallel support arms placed in a same horizontal plane, and a carrying structure. The first and second parallel support arms are mounted on the carrying structure. The first parallel support arms (3) are associated with controllable units (5, 6, 7, 8), which allow simultaneous vertical movement to constitute a first vertically moveable horizontal support plane for the longitudinal continuous bars. The second parallel support arms (4) extend parallel to the first support arms to constitute a second horizontal support plane for the longitudinal continuous bars. The first and second horizontal support planes are partially superposed. The carrying structure is made up of vertical poles equipped with the first and second parallel support arms. The vertical poles are mounted on a rail structure (17), which extends according to a perpendicular direction to the first and second parallel support arms to support an adjustment of spacing between the vertical poles. Each vertical pole is equipped with a control pedal connected to a desired programmable automat. After selecting the poles to manufacture the desired reinforcement, the mounted and the synchronized descent of different movable support arms constitute the first support plane. The first parallel support arms are assembled on the carrying structure through a vertically movable cart, which is directed in displacement by means of a vertical endless screw positioned by a motorization. The second parallel support arms are assembled on the carrying structure with a fixed height of 0.70-1.30 m, and are rotatably mounted on the carrying structure around a vertical axis to allow retraction apart from a vertical obstruction of the first support plane. The carrying structure comprises two holdings for the additional removable support arms, which are parallel with the first and second support arms, and a measuring device. The removable support arms form a third support plane above the second support plane. The set of superimposed additional removable support arms confers a positioning choice for the third support plane or confers a possibility for creating several additional support planes. The measuring device allows to determine a height of the first support plane with respect to the second support plane.

Description

INSTALLATION SUPPORT POUR LA FABRICATION D'ARMATURES METALLIQUES ET SON PROCEDE DE MISE EN ŒUVRE SUPPORT INSTALLATION FOR THE MANUFACTURE OF METALLIC FRAMES AND METHOD FOR IMPLEMENTING SAME
La présente invention concerne une installation support pour la fabrication d'armatures métalliques, en particulier d'armatures pour béton constituées de barres filantes longitudinales assemblées par des cadres transversaux.The present invention relates to a support installation for the manufacture of metal reinforcements, in particular reinforcement for concrete consisting of longitudinal rods assembled by transverse frames.
Les armatures métalliques pour béton, constituées de barres filantes longitudinales assemblées par des cadres transversaux, sont classiquement fabriquées sur des installations ou des postes comportant un plan support de hauteur définie formé par les traverses supérieures parallèles d'une pluralité de tréteaux ou chevalets convenablement espacés.The metal reinforcements for concrete, consisting of longitudinal rods assembled by transverse frames, are conventionally manufactured on installations or stations having a support plane of defined height formed by the parallel upper rails of a plurality of trestles or easels suitably spaced.
Ayant connaissance de la structure de l'armature qu'il doit fabriquer, l'opérateur positionne les barres longitudinales de haut sur le plan support. Il soude la partie supérieure des cadres transversaux sur ces barres de haut. Il soude ensuite les éventuelles barres latérales (appelées barres de peau) sur les côtés desdits cadres transversaux, et enfin, les barres filantes de bas sur la partie inférieure des cadres.Having knowledge of the structure of the armature that it must manufacture, the operator positions the longitudinal bars high on the support plane. It welds the top of the transverse frames on these top bars. It then welds any lateral bars (called skin bars) on the sides of said transverse frames, and finally, the bottom bars on the lower part of the frames.
Dans certains cas, des cadres, épingles ou étriers additionnels sont rapportés après soudage des barres de haut.In some cases additional frames, pins or stirrups are reported after welding of the top bars.
Cependant, ces différentes opérations de soudage sont réalisées avec les barres de haut en appui constant sur les tréteaux ou chevalets précités, ceci à une hauteur prédéterminée qui est fixe. Par conséquent, l'opérateur doit réaliser des points de soudage à différentes hauteurs. Il est donc amené à travailler fréquemment de manière courbée, ainsi qu'à s'abaisser puis se relever à de maintes reprises, ce qui s'avère pénible et peut entraîner l'apparition de maladies professionnelles, en particulier des troubles musculo-squelettiques (TMS) D'autre part, l'opérateur doit soutenir certaines barres longitudinales au cours de l'opération de soudage, pour les positionner au niveau correct requis (ceci est valable en particulier pour le soudage des barres de peau), ce qui augmente l'inconfort et la pénibilité de l'opération d'assemblage, et ce qui est source d'erreurs et de malfaçons. De plus, une fois les barres de haut soudées aux cadres, pour les autres barres filantes, le soudeur n'a pas d'autre choix que de les enfiler dans la cage, ce qui en raison de la longueur des pièces, et donc du porte-à-faux, nécessite l'intervention de plusieurs personnes.However, these different welding operations are carried out with the high bars in constant support on the aforementioned trestles or trestles, this at a predetermined height which is fixed. Therefore, the operator must realize welding points at different heights. He is therefore frequently required to work in a curved manner, as well as to lower himself and then to get up again and again, which proves to be painful and can lead to the appearance of occupational diseases, in particular musculoskeletal disorders ( TMS) On the other hand, the operator must support some longitudinal bars during the welding operation, to position them at the correct level required (this is valid in particular for the welding of the skin bars), which increases the 'discomfort and difficulty of the assembly operation, and what is the source of errors and defects. In addition, once the high bars are welded to the frames, for the other bars, the welder has no choice but to put them in the cage, which due to the length of the parts, and therefore the cantilever, requires the intervention of several people.
Le document EP-O 791 416 propose une installation pour la fabrication d'armatures métalliques, comprenant plusieurs poteaux verticaux qui portent des bras mobiles constituant des plans supports pour les différentes barres filantes. Une fois les barres de haut, de peau et de bas convenablement positionnées à leur niveau de hauteur respectif choisi, un chariot mobile horizontalement assure la répartition correcte des cadres transversaux sur la longueur de la cage d'armature à réaliser, avant que l'opérateur réalise les différentes opérations de soudure d'assemblage. Cependant, là encore, l'opérateur doit réaliser les points de soudure à différentes hauteurs, avec les inconvénients précités en terme de pénibilité du travail. De plus, pour chaque armature, il doit alimenter son poste de travail pièce par pièce ; il est en outre obligé d'enfiler les barres filantes dans les cadres déjà en place sur le chariot mobile. La présente invention propose une installation support originale, en particulier pour la fabrication d'armatures métalliques pour béton, qui permet de faciliter les opérations d'assemblage (notamment par soudage) des différents éléments constitutifs de ladite armature, en rendant lesdites opérations moins pénibles et plus précises.The document EP-0 791 416 proposes an installation for the manufacture of metal reinforcements, comprising several vertical posts which carry mobile arms constituting support planes for the various bars. Once high, skin and bottom bars suitably positioned at their chosen respective height level, a horizontally movable carriage ensures the correct distribution of the transverse frames along the length of the reinforcement cage to be achieved, before the operator realizes the different assembly welding operations. However, here again, the operator must achieve the welding points at different heights, with the aforementioned drawbacks in terms of labor hardness. In addition, for each frame, it must feed its workstation piece by piece; he is also obliged to put the bars in the frames already in place on the mobile carriage. The present invention proposes an original support installation, in particular for the manufacture of metal reinforcements for concrete, which makes it possible to facilitate the operations of assembly (in particular by welding) of the various elements constituting said reinforcement, rendering said operations less painful and more precise.
A cet effet, l'installation support conforme à l'invention est caractérisée par le fait qu'elle comprend :For this purpose, the support installation according to the invention is characterized in that it comprises:
- au moins deux premiers bras supports, parallèles, disposés dans le même plan horizontal, lesquels premiers bras sont montés en porte-à-faux sur une structure porteuse, et sont associés à des moyens pilotables qui permettent leur déplacement vertical simultané, parallèlement à eux-mêmes, de manière à constituer un premier plan support horizontal, mobile verticalement (pour la réception d'au moins certaines desdites barres filantes longitudinales), etat least two first parallel support arms, arranged in the same horizontal plane, which first arms are cantilevered on a supporting structure, and are associated with controllable means which allow their simultaneous vertical displacement, parallel to them; same, so as to constitute a first horizontal support plane, vertically movable (for receiving at least some of said longitudinal rods), and
- au moins deux seconds bras supports, parallèles, disposés dans le même plan horizontal, lesquels seconds bras sont montés en porte-à-faux sur ladite structure porteuse et s'étendent parallèlement auxdits premiers bras supports, pour constituer un second plan support horizontal (pour la réception de certaines au moins desdites barres filantes longitudinales), lesdits premiers et seconds plans supports étant au moins partiellement superposés.at least two second parallel support arms arranged in the same horizontal plane, which second arms are cantilevered on said supporting structure and extend parallel to said first support arms, to constitute a second horizontal support plane ( for receiving at least some of said longitudinal rods), said first and second support planes being at least partially superimposed.
De plus, ledit premier plan support horizontal est mobile verticalement au moins entre une hauteur inférieure, située légèrement au-dessus du second plan support horizontal, et une hauteur supérieure extrême qui est séparée de ladite hauteur inférieure au moins de la distance maximale séparant les barres de haut et les barres de bas des différents modèles possibles d'armatures, de manière à permettre une soudure, avec les cadres transversaux, des filants de haut, posés sur lesdits premiers bras, légèrement au-dessus dudit second plan, et à permettre ensuite une soudure, avec lesdits cadres transversaux, éventuellement des filants intermédiaires de peau et des filants de bas, posés sur lesdits seconds bras, ceci après soulèvement de l'association filants de haut/cadres transversaux, par lesdits premiers bras, l'intégralité desdites opérations de soudure pouvant ainsi être réalisée toujours dans le même plan ou sensiblement dans le même plan. Le plan support mobile peut notamment être utilisé pour recevoir les barres filantes de haut de l'armature, les barres de peau et les barres de bas pouvant être positionnées en attente sur le second plan support. L'opérateur peut alors positionner le plan support mobile à la hauteur souhaitée, en fonction de ce qu'il considère être sa meilleure posture, pour réaliser le soudage des cadres transversaux sur les barres de haut (le plan support mobile est pour cela placé juste au-dessus du second plan support, en particulier à peu près 100 mm au-dessus). Une fois cette opération réalisée, il élève le plan support mobile pour souder les éventuelles barres de peau en appui sur le second plan support (cette opération pouvant être réalisée à plusieurs reprises, en fonction du nombre de couches de barres de peau), puis il soulève encore le plan support mobile à la hauteur souhaitée, pour souder la partie inférieure des cadres transversaux sur les barres filantes de bas.In addition, said first horizontal support plane is vertically movable at least between a lower height, located slightly above the second horizontal support plane, and an upper extreme height which is separated from said lower height by at least the maximum distance between the bars. high and the bottom bars of the various possible models of frames, so as to allow a weld, with the transverse frames, high wire, placed on said first arms, slightly above said second plane, and then allow a weld, with said transverse frames, possibly intermediate skin strands and bottom threads, placed on said second arms, this after lifting of the association high threads / transverse frames, said first arms, all of said welding operations can thus be carried out always in the same plane or substantially in the same plan. The mobile support plane may in particular be used to receive the rods from the top of the frame, the skin bars and the bottom bars can be positioned waiting on the second support plane. The operator can then position the mobile support plane at the desired height, according to what he considers to be his best posture, to achieve the welding of the transverse frames on the high bars (the mobile support plane is therefore placed just above the second support plane, in particular about 100 mm above). Once this operation is performed, it raises the mobile support plane to weld any skin bars resting on the second support plane (this operation can be performed several times, depending on the number of layers of skin bars), then again raises the mobile support plane to the desired height, for welding the lower part of the transverse frames on the bottom bars.
Le cas échéant, des opérations de pose de cadres transversaux, épingles ou étriers additionnels peuvent être réalisées après la pose des barres de haut.If necessary, operations of installation of transverse frames, pins or additional stirrups can be performed after the installation of the high bars.
Une telle installation support s'avère particulièrement ergonomique du fait qu'elle permet à l'opérateur de souder toujours pratiquement à la même hauteur choisie. Elle permet de limiter les efforts physiques des soudeurs et de minimiser les gestes et les manipulations. Elle contribue ainsi à améliorer les conditions de travail et donc la qualité de celui-ci, et elle permet aussi de prévenir les risques de maladies professionnelles. D'autre part, cette installation offre une réponse aux exigences industrielles en matière de délai et de qualité. Elle permet de réaliser des gains de productivité et de limiter les risques de rupture des flux.Such a support installation is particularly ergonomic because it allows the operator to always solder almost at the same height chosen. It limits the physical efforts of welders and minimizes gestures and manipulations. It thus contributes to improving the working conditions and thus the quality of it, and it also helps to prevent the risks of occupational diseases. On the other hand, this installation offers a response to industrial requirements in terms of time and quality. It makes it possible to achieve productivity gains and to limit the risks of flow failure.
Cette installation support propose des appuis coordonnés qui assurent l'alignement des soudures et la mise en hauteur. Elle permet un accès plus aisé aux points à souder et assure ainsi des soudures de meilleure qualité.This support installation offers coordinated supports that ensure the alignment of the welds and the height adjustment. It allows easier access to weld points and ensures better welds.
Selon une forme de réalisation particulièrement intéressante, la structure porteuse est constituée d'une pluralité de poteaux verticaux qui sont équipés chacun d'un desdits premiers bras supports mobiles, et d'un desdits seconds bras supports. Dans ce cadre, les poteaux verticaux sont avantageusement montés roulants sur une structure de rails qui s'étend selon une direction perpendiculaire aux premiers et seconds bras supports, de manière à autoriser un réglage de l'écartement entre lesdits poteaux, et aussi à permettre un choix du nombre de poteaux nécessaires à la fabrication de l'armature souhaitée.According to a particularly interesting embodiment, the carrying structure consists of a plurality of vertical posts which are each equipped with one of said first movable support arms, and one of said second support arms. In this context, the vertical posts are advantageously mounted on a rolling rail structure which extends in a direction perpendicular to the first and second support arms, so as to allow adjustment of the spacing between said posts, and also to allow a choice of the number of poles necessary for the manufacture of the desired reinforcement.
Toujours dans ce cadre, chaque poteau est avantageusement équipé d'une pédale de commande reliée à un automate programmable qui, après sélection des différents poteaux choisis pour fabriquer l'armature souhaitée, permet à l'opérateur d'assurer la montée ou la descente synchronisée des différents bras supports mobiles constituant le premier plan support (cette opération peut être réalisée à partir de l'une ou l'autre desdites pédales de commande). Selon une forme de réalisation particulière, les premiers bras supports sont chacun montés sur leur structure porteuse par l'intermédiaire d'un chariot mobile verticalement, lequel chariot est manœuvré en translation au moyen d'une vis sans fin verticale entraînée en rotation par une motorisation.Still in this context, each post is advantageously equipped with a control pedal connected to a programmable controller which, after selecting the various poles chosen to manufacture the desired armature, allows the operator to ensure the synchronized rise or descent. different movable support arms constituting the first support plane (this operation can be performed from one or other of said control pedals). According to a particular embodiment, the first support arms are each mounted on their supporting structure by means of a vertically movable carriage, which carriage is maneuvered in translation by means of a vertical worm driven in rotation by a motorization .
De préférence, les seconds bras supports sont montés sur leur structure porteuse à un niveau fixe correspondant à la hauteur de soudage la moins pénible, à savoir une hauteur comprise entre 0,70 m et 1 ,30 m, en particulier proche de 0,90 m à 1 ,10 m.Preferably, the second support arms are mounted on their supporting structure at a fixed level corresponding to the least painful welding height, namely a height of between 0.70 m and 1.30 m, in particular close to 0.90 m to 1, 10 m.
Selon une autre particularité très intéressante, les seconds bras supports sont montés pivotants sur leur structure porteuse, autour d'un axe vertical, pour permettre leur escamotage en dehors d'une partie au moins de l'encombrement vertical du premier plan support. De la sorte, après fabrication, l'armature terminée peut être reposée sur le sol ou sur une structure de réception appropriée, simplement par la descente du premier plan support mobile, sans être gênée par la présence du second plan support (dont les bras constitutifs auront été escamotés préalablement). Toujours selon l'invention, la structure support comporte au moins deux logements pour la réception de deux bras supports supplémentaires, amovibles, parallèles entre eux et parallèles auxdits premiers et seconds plans supports, permettant la formation d'un troisième plan support au-dessus dudit second plan support. De préférence, l'installation comporte deux ensembles de logements superposés, pour la réception desdits bras supplémentaires, conférant un choix de positionnement permettant d'adapter le niveau vertical dudit troisième plan support, ou conférant la possibilité de créer plusieurs plans supports complémentaires.According to another very interesting feature, the second support arms are pivotally mounted on their supporting structure, around a vertical axis, to allow their retraction out of at least a portion of the vertical space of the first support plane. In this way, after manufacture, the finished armature can be rested on the ground or on a suitable receiving structure, simply by the descent of the first movable support plane, without being hindered by the presence of the second support plane (whose constituent arms have been retracted beforehand). Still according to the invention, the support structure comprises at least two housings for receiving two additional support arms, removable, parallel to each other and parallel to said first and second support planes, allowing the formation of a third support plane above said second support plane. Preferably, the installation comprises two sets of superimposed housings, for the reception of said additional arms, conferring a choice of positioning to adapt the vertical level of said third support plane, or conferring the possibility of creating several complementary support planes.
Selon encore une autre particularité, la structure porteuse comporte un dispositif de mesure permettant de déterminer la hauteur du premier plan support mobile par rapport à une référence, et en particulier par rapport au niveau du second plan support.According to yet another particularity, the carrying structure comprises a measuring device for determining the height of the first support plane mobile with respect to a reference, and in particular with respect to the level of the second support plane.
L'invention concerne encore le procédé de fabrication d'une armature métallique constituée de barres filantes longitudinales assemblées sur plusieurs niveaux de hauteur par des cadres transversaux, lesdites barres filantes longitudinales constituant des barres de haut, des barres de bas et éventuellement des barres intermédiaires dites de peau, pour la mise en œuvre de l'installation selon les revendications 1 à 10, ce procédé consistant :The invention also relates to the method of manufacturing a metal reinforcement consisting of longitudinal rods assembled on several levels of height by transverse frames, said longitudinal rods constituting rods of high, bottom bars and possibly so-called intermediate bars of skin, for the implementation of the installation according to claims 1 to 10, this method consisting:
- à positionner lesdites barres de haut sur un premier plan support et lesdites barres de bas, avec éventuellement lesdites barres de peau, sur un second plan support, ledit second plan support étant disposé juste sous le premier, l'ensemble desdites barres filantes étant ceinturé par lesdits cadres transversaux,- positioning said top bars on a first support plane and said bottom bars, with possibly said skin bars, on a second support plane, said second support plane being arranged just below the first, all of said rods being belted by said transverse frames,
- à souder lesdites barres de haut sur lesdits cadres transversaux,soldering said top bars to said transverse frames,
- à relever l'ensemble barres de haut/cadres transversaux, tout en maintenant fixe ledit second plan support, pour réaliser la soudure convenable desdites barres intermédiaires éventuellement, puis desdites barres de bas, les opérations de soudure pouvant ainsi être réalisées toujours dans le même plan ou sensiblement dans le même plan.- To raise the set of upper bars / transverse frames, while maintaining fixed said second support plane, to achieve suitable welding of said intermediate bars possibly, then said bottom bars, the welding operations can thus be carried out always in the same plan or substantially in the same plane.
Plus précisément, ce procédé consiste avantageusement : - à positionner une série de filants sur le premier plan support,More specifically, this process advantageously consists in: positioning a series of strands on the first support plane;
- à sélectionner dans ladite série les différents filants longitudinaux nécessaires à la fabrication d'une armature, en les ramenant vers l'extrémité en porte-à-faux des premiers bras supports,selecting in said series the different longitudinal threads necessary for the manufacture of an armature, by bringing them towards the cantilevered end of the first support arms,
- à positionner les cadres transversaux sur ladite sélection de filants, - à transférer les filants de bas et éventuellement les filants intermédiaires de peau sur les seconds bras supports,positioning the transverse frames on said selection of threads, transferring the bottom threads and possibly the intermediate skin threads onto the second support arms;
- à souder lesdites barres de haut sur lesdits cadres transversaux,soldering said top bars to said transverse frames,
- à relever l'ensemble barres de haut/cadres transversaux au moyen des premiers bras, tout en maintenant fixe ledit second plan support, pour réaliser la soudure desdites barres intermédiaires éventuellement, puis desdites barres de bas.- To raise the set of high bars / transverse frames by means of the first arms, while maintaining fixed said second support plane, to achieve the welding of said intermediate bars possibly, then said bottom bars.
L'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'une forme de réalisation particulière, donnée uniquement à titre d'exemple et représentée sur les dessins annexes dans lesquels :The invention will be further illustrated, without being limited in any way, by the following description of a particular embodiment, given solely by way of example and shown in the accompanying drawings in which:
- la figure 1 est une vue en perspective d'une installation support conforme à la présente invention ; - la figure 2 montre la même installation que la figure 1 , dans laquelle les bras constituant le second plan support ont été escamotés ;- Figure 1 is a perspective view of a support installation according to the present invention; - Figure 2 shows the same installation as Figure 1, wherein the arms constituting the second support plane have been retracted;
- les figures 3 à 10 illustrent, en différentes étapes, une manière possible de mettre en œuvre l'installation illustrée sur les figures 1 et 2. Comme on peut le voir sur la figure 1 , l'installation support, repérée généralement 1 , comprend une structure porteuse constituée d'une pluralité de poteaux verticaux creux 2, d'une hauteur par exemple de 2,5 m ou plus, équipés chacun d'un premier bras horizontal 3 et d'un second bras horizontal 4, parallèles entre eux. Chaque premier bras horizontal 3 s'étend en porte-à-faux à partir de son poteau support 2. Il est monté sur un chariot coulissant 5 mobile verticalement. Le chariot 5 est équipé de galets et il est guidé par des glissières ménagées sur la face avant du poteau 2, ou à l'intérieur de celui-ci. Son déplacement, avec le bras en porte- à-faux 3 est réalisé au moyen d'une vis sans fin verticale, schématisée par la ligne en pointillés 6, intégrée au sein du poteau 2 et entraînée en rotation par une motorisation 7 (par exemple de type motoréducteur frein asynchrone). La coopération entre la vis sans fin 6 et le chariot 5 s'effectue de manière classique par l'intermédiaire d'un écrou en bronze. De préférence, un second écrou assure la sécurité du chariot en cas d'usure des filets du premier écrou en bronze. Ce premier bras support 3 peut être manœuvré en translation verticale pratiquement depuis le sol, au moins jusqu'à une hauteur de 1 ,5 m, et de préférence plus. Sa structure et sa robustesse, ainsi que celles du poteau support 2, sont adaptées selon les charges maximales destinées à être supportées.FIGS. 3 to 10 illustrate, in different steps, a possible way to implement the installation illustrated in FIGS. 1 and 2. As can be seen in FIG. 1, the support installation, generally labeled 1, comprises a support structure consisting of a plurality of hollow vertical columns 2, for example a height of 2.5 m or more, each equipped with a first horizontal arm 3 and a second horizontal arm 4, parallel to each other. Each first horizontal arm 3 extends cantilevered from its support post 2. It is mounted on a sliding carriage 5 movable vertically. The carriage 5 is equipped with rollers and is guided by slides provided on the front face of the column 2, or inside thereof. Its displacement, with the cantilevered arm 3 is achieved by means of a vertical worm, schematized by the dotted line 6, integrated within the column 2 and driven in rotation by a motor 7 (for example asynchronous brake motor type). The cooperation between the worm 6 and the carriage 5 is carried out conventionally by means of a bronze nut. Preferably, a second nut ensures the safety of the carriage in case of wear of the threads of the first bronze nut. This first support arm 3 can be maneuvered in vertical translation substantially from the ground, at least to a height of 1.5 m, and preferably more. Its structure and robustness, as well as those of the support post 2, are adapted according to the maximum loads to be supported.
La motorisation 7 est pilotable au moyen d'une pédale de commande 8, de type double contacteur, directement accessible à l'opérateur à proximité du poteau 2, du côté du premier bras support 3. Cette pédale de commande 8 permet la manœuvre de ce premier bras support 3 à volonté, en montée ou en descente.The engine 7 is controllable by means of a control pedal 8, double contactor type, directly accessible to the operator near the pole 2, the side of the first support arm 3. This control pedal 8 allows the maneuver of this first support arm 3 at will, uphill or downhill.
D'autre part, la pédale 8 et la motorisation 7 sont reliées à une armoire de commande intégrant un automate programmable 9, dont la fonction sera détaillée plus loin.On the other hand, the pedal 8 and the actuator 7 are connected to a control cabinet incorporating a programmable controller 9, whose function will be detailed later.
Le second bras support 4 s'étend horizontalement en porte-à-faux à partir du poteau 2. Sa surface d'appui horizontale 10 se situe à une hauteur fixe par rapport au sol, correspondant à un niveau permettant d'assurer une opération de soudage avec confort. Cette hauteur est comprise entre 0,7 m et 1 ,30 m, de préférence entre 0,90 m et 1 ,10 m. Ce second bras support 4 est monté pivotant sur le poteau 2, autour d'un axe vertical 11 , afin de pouvoir être escamoté sur le côté, de la manière illustrée sur la figure 2. Il est avantageusement prévu des moyens désactivables (non représentés) permettant le verrouillage de la position active du bras support 4 (c'est-à-dire la position dans laquelle le bras 4 est parallèle au premier bras support 3, tel qu'illustré figure 1 ).The second support arm 4 extends horizontally cantilevered from the post 2. Its horizontal bearing surface 10 is at a fixed height with respect to the ground, corresponding to a level making it possible to perform an operation of welding with comfort. This height is between 0.7 m and 1.30 m, preferably between 0.90 m and 1.10 m. This second support arm 4 is pivotally mounted on the post 2, around a vertical axis 11, so that it can be retracted on the side, as illustrated in FIG. 2. Disable means are advantageously provided (not shown). allowing the locking of the active position of the support arm 4 (that is to say the position in which the arm 4 is parallel to the first support arm 3, as shown in Figure 1).
Le second bras support 4 est légèrement décalé sur le côté, par rapport au plan vertical de déplacement du premier bras support 3, pour ne pas gêner le déplacement vertical de ce dernier. Il s'étend de préférence sur une longueur un peu supérieure à celle du premier bras support 3, de manière, comme on le verra plus loin, à faciliter la réception de barres filantes préalablement stockées en appui sur ledit premier bras support 3.The second support arm 4 is slightly offset on the side, relative to the vertical plane of movement of the first support arm 3, so as not to hinder the vertical movement of the latter. It preferably extends over a length slightly greater than that of the first support arm 3, so as will be seen later on, to facilitate the reception of previously stored rods bearing on said first support arm 3.
Comme on peut le voir sur la figure 1 notamment, la surface d'appui 10 du second bras support 4 est constituée d'un rouleau 12 qui est monté fou en rotation autour d'un axe longitudinal 12'. Ce rouleau 12 permet d'optimiser le glissement latéral des barres filantes en appui sur le second bras support 4.As can be seen in Figure 1 in particular, the bearing surface 10 of the second support arm 4 consists of a roller 12 which is mounted idle in rotation about a longitudinal axis 12 '. This roller 12 optimizes the lateral sliding of the rods bearing on the second support arm 4.
Juste au-dessus du second bras support 4, on remarque la présence de deux platines verticales parallèles, l'une avant 13 et l'autre arrière 13', solidaires du poteau 2, espacées l'une de l'autre ici d'une distance correspondant à la largeur dudit poteau 2. Ces deux platines 13 et 13' sont chacune munies d'une série d'orifices superposés 14, 14', alignés verticalement. Les orifices 14 de la platine avant 13 sont chacun disposés en correspondance avec l'un des orifices 14' de la platine arrière 13' (c'est-à- dire de manière coaxiale), pour former un logement horizontal 15, apte à recevoir un bras complémentaire 16, représenté en pointillés. La série de logements 15 superposés forme une sorte de râtelier qui permet un positionnement amovible d'un bras support supplémentaire 16 au niveau souhaité, ou encore un positionnement de plusieurs bras supplémentaires 16, sur plusieurs niveaux. Ce ou ces bras supplémentaires 16 s'étendent parallèlement aux premier et second bras support 3, 4. Il est ou ils sont légèrement décalés sur le côté par rapport au plan vertical de déplacement du premier bras support 3, pour ne pas gêner le déplacement vertical de ce dernier.Just above the second support arm 4, there is the presence of two vertical parallel plates, one before 13 and the other rear 13 ', integral with the post 2, spaced from each other here a distance corresponding to the width of said post 2. These two plates 13 and 13 'are each provided with a series of superimposed orifices 14, 14', aligned vertically. The orifices 14 of the front plate 13 are each arranged in correspondence with one of the orifices 14 'of the rear plate 13' (that is to say coaxially), to form a horizontal housing 15, able to receive a complementary arm 16, shown in dotted lines. The series of superimposed housings 15 form a kind of rack which allows a removable positioning of an additional support arm 16 at the desired level, or a positioning of several additional arms 16, on several levels. This or these additional arms 16 extend parallel to the first and second support arms 3, 4. It is or they are slightly offset on the side relative to the vertical plane of displacement of the first support arm 3, to not hinder the vertical movement of the last.
Les différents poteaux 2 sont montés roulants sur une même structure de rails 17, pour permettre leur rapprochement ou leur écartement à volonté les uns des autres par simple poussée manuelle, cela selon une direction qui est perpendiculaire aux bras supports 3, 4 et éventuellement 16 précités. D'autre part, chaque poteau 2 est équipé d'un dispositif de mesure 18 permettant d'indiquer à l'opérateur le niveau en hauteur de la surface d'appui du premier bras support 3, par rapport au niveau du second bras support 4. Ce dispositif de mesure 18 peut être constitué d'une simple règle graduée ; il peut aussi s'agir d'un encodeur avec affichage digital, tenant compte de la rotation de l'arbre du motoréducteur 7.The various posts 2 are mounted on a rolling track on a single structure 17, to allow their approximation or spacing at will from each other by simple manual push, that in a direction that is perpendicular to the support arms 3, 4 and possibly 16 above . On the other hand, each post 2 is equipped with a measuring device 18 making it possible to indicate to the operator the height level of the bearing surface of the first support arm 3, relative to the level of the second support arm 4 This measuring device 18 may consist of a simple graduated rule; it can also be an encoder with digital display, taking into account the rotation of the shaft of the geared motor 7.
L'installation support 1 comprend une pluralité de poteaux 2, tous identiques ou similaires, disposés les uns à côté des autres sur leur structure de guidage 17. Les différents poteaux 2 sont tous orientés dans le même sens de sorte que leurs bras supports 3, 4 et éventuellement 16 s'étendent tous parallèlement les uns aux autres.The support installation 1 comprises a plurality of posts 2, all identical or similar, arranged next to each other on their guide structure 17. The various posts 2 are all oriented in the same direction so that their support arms 3, 4 and possibly 16 extend all parallel to each other.
Les moyens de manœuvre 7, 8 des bras mobiles 3 de tous les poteaux 2 sont connectés à l'automate programmable 9 assurant la gestion de l'ensemble des configurations. En particulier, cet automate 9 est programmé de manière, tenant compte de la sélection préalable des poteaux 2 choisis pour fabriquer une armature (parmi l'ensemble des poteaux disponibles), à assurer le positionnement des premiers bras supports 3 au même niveau en hauteur, puis à permettre la montée et la descente synchronisées des différents bras supports 3 correspondants, ceci à partir d'une seule des pédales de commande 8 associée à l'un des poteaux sélectionnés.The operating means 7, 8 of the movable arms 3 of all the posts 2 are connected to the programmable controller 9 ensuring the management of all configurations. In particular, this automaton 9 is programmed so as to take into account the prior selection of the posts 2 chosen to manufacture an armature (from the set of available poles), to ensure the positioning of the first support arms 3 at the same height level, then to allow the synchronized rise and fall of the different support arms 3 corresponding, this from only one of the control pedals 8 associated with one of the selected poles.
Outre cette gestion des configurations de groupes, l'automate 9 assure la gestion des fins de course haut et bas des chariots mobiles 5, ainsi que des arrêts d'urgence éventuels ; il assure également le contrôle thermique des motoréducteurs 7. A partir du plan de l'armature qu'il doit fabriquer, l'opérateur sélectionne donc les poteaux supports 2 qu'il souhaite utiliser (en emplacement et en nombre). Ensuite, il positionne correctement les différents poteaux supports 2 les uns par rapport aux autres, par déplacement manuel sur la structure de guidage 17.In addition to managing group configurations, the controller 9 manages the top and bottom limit switches of the mobile carriages 5, as well as any emergency stops; it also provides thermal control of the geared motors 7. From the plane of the armature that it must manufacture, the operator therefore selects the support posts 2 he wants to use (location and number). Then, it correctly positions the different support posts 2 relative to each other, by manual displacement on the guide structure 17.
On comprend que les premiers bras supports 3 des différents poteaux 2 sélectionnés, juxtaposés, forment un plan support horizontal 3' (appelé premier plan support horizontal 3'), qui est propre à servir de plan de dépose et de réception pour certaines des barres filantes longitudinales constitutives de l'armature. Ce premier plan support 3' est mobile verticalement et son niveau peut être adapté à volonté par l'opérateur par le pilotage de l'une des pédales de commande 8, entre des hauteurs inférieure et supérieure extrêmes.It will be understood that the first support arms 3 of the various columns 2 selected, juxtaposed, form a horizontal support plane 3 '(called the first horizontal support plane 3'), which is adapted to serve as a removal and reception plane for some of the bars longitudinal constituent of the frame. This first support plane 3 'is vertically movable and its level can be adapted at will by the operator by controlling one of the control pedals 8 between upper and lower extreme heights.
Les seconds bras supports 4 des différents poteaux 2 sélectionnés forment un plan support horizontal 4' (appelé second plan support 4'), dont le niveau en hauteur est fixe, propre, lui aussi, à servir de plan de dépose et de réception pour certaines des barres filantes longitudinales constitutives de l'armature.The second support arms 4 of the various columns 2 selected form a horizontal support plane 4 '(called second support plane 4'), whose height level is fixed, clean, too, to serve as a plan of removal and reception for some longitudinal rods constituent of the frame.
En outre, les éventuels bras complémentaires 16 forment un ou plusieurs plans supports supplémentaires horizontaux 16'. Ces différents plans supports 3', 4' et éventuellement 16' sont disposés les uns au-dessus des autres (ou confondus pour certains, en fonction du positionnement du premier plan support 3') ; ils sont au moins partiellement superposés, c'est-à-dire disposés au moins partiellement dans le même encombrement vertical.In addition, the optional complementary arms 16 form one or more additional horizontal support planes 16 '. These different support planes 3 ', 4' and possibly 16 'are arranged one above the other (or some for some, depending on the positioning of the first support plane 3'); they are at least partially superimposed, that is to say arranged at least partially in the same vertical space.
Dans le mode de réalisation illustré, les différents plans supports 3', 4' et 16' ont la même longueur, délimitée par les poteaux supports 2 d'extrémités ; ils ont également sensiblement la même largeur, correspondant à la longueur des bras 3, 4 et 16, et ils sont quasiment intégralement superposés.In the illustrated embodiment, the different support planes 3 ', 4' and 16 'have the same length, delimited by the support posts 2 of ends; they also have substantially the same width, corresponding to the length of the arms 3, 4 and 16, and they are almost completely superimposed.
Comme on peut le voir sur la figure 2, l'escamotage des seconds bras supports 4As can be seen in FIG. 2, the retraction of the second support arms 4
(réalisé manuellement) s'effectue par pivotement sur un secteur angulaire voisin de 90°. Cet escamotage permet de supprimer quasiment intégralement le second plan support 4', et de libérer presque totalement l'encombrement vertical sous le premier plan support 3'.(done manually) is made by pivoting on an angular sector close to 90 °. This retraction makes it possible to almost completely remove the second support plane 4 ', and to release almost completely the vertical space under the first support plane 3'.
A partir de cette installation, l'opérateur utilise la mobilité du premier plan support 3' pour souder à une hauteur qui est la plus confortable pour lui les barres filantes de haut sur la partie supérieure des cadres transversaux (cette hauteur de soudage est à priori la plus proche possible du second plan support 4'). Dans la suite de la procédure, les barres filantes de haut restent en permanence en appui sur les différents bras supports mobiles 3.From this installation, the operator uses the mobility of the first support plane 3 'to weld at a height which is most comfortable for him the high bars on the upper part of the transverse frames (this welding height is a priori as close as possible to the second support plane 4 '). In the rest of the procedure, the high bars always remain in support on the various mobile support arms 3.
Cette mobilité permet ensuite à l'opérateur d'élever la cage formée par l'ensemble barres de haut/cadres transversaux pour positionner correctement ces cadres transversaux (et éventuellement des cadres intermédiaires) par rapport au(x) lit(s) de barres filantes de peau et de bas, préalablement disposées sur le second plan supportThis mobility then allows the operator to raise the cage formed by the set of upper bars / transverse frames to correctly position these transverse frames (and possibly intermediate frames) relative to the (x) bed (s) of rods of skin and stockings, previously arranged on the second support plane
4' et éventuellement sur le ou les plans supports supplémentaires 16'. Cela évite à l'opérateur d'avoir à porter lesdites barres filantes lors de l'opération de soudage. Pour réaliser ce positionnement convenable, défini par le plan de l'armature, l'opérateur est assisté par le dispositif de mesure 18.4 'and possibly on the or more support planes 16'. This avoids the operator having to wear said rods during the welding operation. To achieve this proper positioning, defined by the plane of the armature, the operator is assisted by the measuring device 18.
Une fois l'assemblage finalisé, l'armature est déposée au sol, ou sur une structure de stockage mobile, par abaissement du plan mobile 3', après escamotage des bras supports 4 et retrait des éventuels bras supplémentaires 16. Une manière possible d'utiliser cette installation support 1 , pour la fabrication d'armatures simples, est illustrée en différentes séquences sur les figures 3 à 10.Once assembly is finalized, the armature is deposited on the ground, or on a mobile storage structure, by lowering the mobile plane 3 ', after retraction of the support arms 4 and removal of any additional arms 16. One possible way of using this support installation 1, for the manufacture of simple reinforcements, is illustrated in various sequences in FIGS. 3 to 10.
Tel qu'illustré sur la figure 3, la première opération consiste à déposer l'ensemble des barres filantes nécessaires à la réalisation de la série de pièces sur le plan support mobile 3' formé par la juxtaposition des premiers bras supports 3, en position de retrait, proche des poteaux 2 ; ensuite, dans le paquet, on sélectionne en faisant glisser vers l'avant les barres filantes de haut 20, de peau 21 et de bas 22 nécessaires à la fabrication de l'armature.As illustrated in FIG. 3, the first operation consists in depositing all the bars necessary for the production of the series of parts on the mobile support plane 3 'formed by the juxtaposition of the first support arms 3, in the position of withdrawal, close to the posts 2; then, in the package, is selected by sliding forward of the high bars 20, skin 21 and bottom 22 necessary for the manufacture of the frame.
Ensuite, on transfère manuellement les barres filantes de peau 21 et de bas 22 sur le second plan support 4' ; les barres filantes de haut 20 restant sur le premier plan support mobile 3' (figure 4). Sur les figures 3 et 4 en particulier, on remarque la présence d'une butée à l'extrémité libre des bras 4, qui optimise le maintien des barres filantes 21 et 22.Then, the skin and bottom sliders 21 and 22 are manually transferred to the second support plane 4 '; the remaining high bars 20 remaining on the first movable support plane 3 '(Figure 4). In FIGS. 3 and 4 in particular, the presence of a stop at the free end of the arms 4 is noted, which optimizes the holding of the rods 21 and 22.
Une fois cette opération de transfert finalisée, on positionne les cadres transversaux 23 en appui sur les barres filantes de haut 20, elles-mêmes en appui sur le premier plan support mobile 3', et on soude lesdites barres de haut 20 sur la partie supérieure desdits cadres transversaux 23 (figure 5). Cette opération de soudure est réalisée à un niveau le plus proche possible du second plan support 4', considéré comme le plan de soudage ergonomiquement optimum. Elle peut en particulier être réalisée environ 100 mm au-dessus du plan support 4', tenant compte du diamètre maximal des filants et de l'épaisseur des bras mobiles 3. On notera ici que l'installation peut avantageusement être équipée d'un système de capteurs pour bloquer la descente des bras 3 avant qu'ils n'interfèrent avec les barres filantes posées sur les bras fixes 4. L'opération suivante, illustrée sur la figure 6, consiste à élever le plan support mobile 3' jusqu'à ce que le second plan support 4' atteigne le niveau auquel les barres de peau 21 doivent être soudées sur les côtés des cadres 23. La soudure correspondante est alors réalisée par l'opérateur.Once this transfer operation has been finalized, the transverse frames 23 are positioned in abutment on the high-wire bars 20, themselves bearing on the first movable support plane 3 ', and said upper bars 20 are welded on the upper part. said transverse frames 23 (Figure 5). This welding operation is performed at a level as close as possible to the second support plane 4 ', considered as the ergonomically optimum welding plane. It can in particular be made approximately 100 mm above the support plane 4 ', taking into account the maximum diameter of the threads and the thickness of the movable arms 3. It should be noted here that the installation can advantageously be equipped with a system sensors to block the descent of the arms 3 before they interfere with the rods placed on the fixed arms 4. The following operation, illustrated in Figure 6, is to raise the mobile support plane 3 'to that the second support plane 4 'reaches the level at which the skin bars 21 must be welded to the sides of the frames 23. The corresponding welding is then performed by the operator.
Tel qu'illustré sur la figure 7, on élève encore le plan support mobile 3' jusqu'à ce que les barres de bas 22 arrivent au contact de la partie inférieure des cadres 23, puis on soude lesdites barres de bas 22 sur lesdits cadres transversaux 23.As illustrated in FIG. 7, the mobile support plane 3 'is further raised until the bottom bars 22 come into contact with the lower part of the frames 23, and then said bottom bars 22 are welded to said frames transversal 23.
L'armature 24 ainsi fabriquée est soulevée pour libérer le second plan support 4'. Les seconds bras supports 4 peuvent alors être escamotés latéralement pour libérer l'encombrement vertical de l'armature (figure 8). II suffit ensuite d'abaisser le premier plan support 3' pour déposer l'armature 24 sur un transbordeur 25 adapté, préalablement convenablement positionné par-dessous (figure 9).The armature 24 thus manufactured is raised to release the second support plane 4 '. The second support arms 4 can then be retracted laterally to release the vertical bulk of the frame (Figure 8). It then suffices to lower the first support plane 3 'to deposit the armature 24 on a suitable ferry 25, previously properly positioned from below (Figure 9).
On évacue enfin l'armature 24 fabriquée vers le stock tampon (figure 10). L'installation est prête pour un nouveau cycle de fabrication, après repositionnement des seconds bras supports 4 parallèlement aux premiers bras mobiles 3.Finally, the reinforcement 24 manufactured is evacuated to the buffer stock (FIG. 10). The installation is ready for a new manufacturing cycle, after repositioning the second support arms 4 parallel to the first movable arms 3.
La mise en œuvre opérationnelle de l'installation pourra être quelque peu différente de celle décrite ci-dessus, en fonction de la structure de l'armature à fabriquer, ou en fonction des habitudes ou expériences des soudeurs.The operational implementation of the installation may be somewhat different from that described above, depending on the structure of the reinforcement to be manufactured, or depending on the habits or experiences of the welders.
Par exemple, les cadres transversaux 23 peuvent très bien être positionnés autour des différentes barres filantes 20, 21 , et 22 en appui sur les bras mobiles 3 (avant le transfert des barres de peau 21 et de bas 22 sur les bras 4), de manière à limiter leur ouverture d'insertion nécessaire. Des bras supplémentaires 16 tels que mentionnés précédemment, sont utilisés pour la création de plans supports complémentaires, en particulier pour la fabrication d'armatures plus complexes, comportant notamment des cadres intermédiaires (en particulier on créera un plan horizontal additionnel par cadre fermé additionnel dans la section de la pièce). A titre de variante, on notera que l'ensemble des bras supports 3, 4 et 16 peuvent être montés sur une même structure porteuse, par exemple fixée à un mur d'appui. D'autre part, une installation simplifiée peut être constituée d'un poteau support unique équipé d'une structure mobile (formée d'au moins deux bras parallèles) constituant le premier plan support mobile 3', et d'une structure fixe (formée d'au moins deux bras parallèles) constituant le second plan support 4' ; la structure mobile peut alors avantageusement être constituée d'un ou de plusieurs bras centraux, associé(s) à des bras d'extrémités mobiles latéralement.For example, the transverse frames 23 may very well be positioned around the various bars 20, 21, and 22 bearing on the movable arms 3 (before the transfer of the skin bars 21 and bottom 22 on the arms 4), in order to limit their necessary insertion opening. Additional arms 16 as mentioned above, are used for the creation of complementary support planes, in particular for the manufacture of more complex reinforcement, including including intermediate frames (in particular an additional horizontal plane will be created by additional closed frame in the section of the room). As a variant, it will be noted that all the support arms 3, 4 and 16 may be mounted on the same supporting structure, for example fixed to a support wall. On the other hand, a simplified installation can consist of a single support post equipped with a mobile structure (formed of at least two parallel arms) constituting the first movable support plane 3 ', and a fixed structure (formed at least two parallel arms) constituting the second support plane 4 '; the mobile structure can then advantageously consist of one or more central arms associated with laterally movable end arms.
On comprend que le poste de soudage ergonomique conforme à l'invention soulage le travail des soudeurs en limitant leurs efforts physiques et en minimisant les gestes et les manipulations de pièces. Il contribue à améliorer les conditions de travail et donc la qualité de celui-ci.It is understood that the ergonomic welding station according to the invention relieves the work of welders by limiting their physical effort and minimizing gestures and handling parts. It helps to improve working conditions and therefore the quality of it.
D'autre part, ce poste optimise l'assemblage. Il respecte le flux naturel de la production et le travail de l'opérateur qui conduit jusqu'au produit fini sans création artificielle de produits semi-finis. L'alignement en hauteur des barres filantes sur les cadres transversaux s'effectue naturellement par la synchronisation des appuis. Il n'est plus nécessaire de soulever les barres pour pointer la soudure. Ce poste optimise donc l'assemblage et permet de réaliser des gains de productivité. En outre, cette installation s'adapte à toutes les configurations. Les différents poteaux supports 2, alignés sur rails, permettent une utilisation par groupe, en fonction de la géométrie de l'armature à assembler, la gestion des différentes configurations étant assurée par l'automate programmable.On the other hand, this post optimizes the assembly. It respects the natural flow of production and the work of the operator which leads to the finished product without artificial creation of semi-finished products. The height alignment of the rods on the transverse frames is naturally done by the synchronization of the supports. It is no longer necessary to lift the bars to point the weld. This item optimizes assembly and allows productivity gains. In addition, this installation adapts to all configurations. The different support posts 2, aligned on rails, allow use in groups, depending on the geometry of the frame to be assembled, the management of the different configurations being provided by the programmable controller.
D'autre part, en association avec une série de transbordeurs 25, l'installation permet de supprimer les pertes de temps liées aux attentes fréquentes des ponts roulants classiques. On the other hand, in combination with a series of transporters 25, the installation eliminates the loss of time related to the frequent expectations of conventional overhead cranes.
