Description
La présente invention concerne un dispositif pour le transfert libre de pièces adressées successivement à une pluralité de postes de travail.The present invention relates to a device for the free transfer of parts addressed successively to a plurality of work stations.
On connait déjà, par exemple par le document FR-A-2 009 034, un dispositif pour le transport de pièces devant être adressées successivement à une pluralité de postes de travail. Ce dispositif comporte un transporteur sans fin défilant devant lesdits postes de travail et entrainant par friction des palettes porte-pièces reposant à plat sur ledit transporteur.We already know, for example from document FR-A-2 009 034, a device for transporting parts to be addressed successively to a plurality of workstations. This device comprises an endless conveyor running past said work stations and frictionally driving workpiece pallets resting flat on said conveyor.
Le mode de transport attaché à un tel dispositif est dit libre, car les palettes individuelles sont indépendantes les unes des autres et peuvent être sélectivement arrêtées dans leur mouvement de défilement, soit en les soulevant dudit transporteur sans fin, soit en transformant la friction d'entraînement en friction de glissement.The mode of transport attached to such a device is said to be free, because the individual pallets are independent of each other and can be selectively stopped in their running movement, either by lifting them from said endless conveyor, or by transforming the friction of sliding friction drive.
Par ailleurs, par le document FR-A-2 512 723, on connatt une installation pour l'assemblage et/ou l'usinage de pièces portées par des palettes circulantes et immobilisables. Dans cette installation connue, lesdites palettes ne sont pas supportées par un transporteur sans fin, mais par une voie fixe de glissement et des moyens d'entraînement par friction desdites palettes sont prévus latéralement à ladite voie. De plus, afin de réaliser ce qu'il est convenu d'appeler dans la technique un atelier flexible, c'est-à-dire une installation facilement modifiable pour être adaptable aussi bien que possible à de multiples desiderata d'assemblage ou d'usinage, ladite installation est composée d'une multiplicité de modules assemblables à une ossature commune.A cet effet, cette ossature commune comprend des traverses et chacun des modules présente des moyens pour être enfilé sur les traverses à la manière d'un tiroir et être dégagé suivant un mouvement inverse.Furthermore, from document FR-A-2,512,723, an installation for the assembly and / or machining of parts carried by circulating and immobilizable pallets is known. In this known installation, said pallets are not supported by an endless conveyor, but by a fixed sliding track and means for frictionally driving said pallets are provided laterally to said track. In addition, in order to achieve what is known in the art as a flexible workshop, that is to say an easily modifiable installation to be adaptable as well as possible to multiple desiderata of assembly or machining, said installation is composed of a multiplicity of modules which can be assembled to a common frame. To this end, this common frame comprises crosspieces and each of the modules has means for being threaded on the crosspieces in the manner of a drawer and being released in reverse motion.
A propos de l'installation connue, mentionnée ci-dessus, on doit remarquer que le mode de support et d'entrainement des palettes est relativement compliqué et coûteux en énergie, du fait que lesdites palettes ne sont pas supportées par un transporteur sans fin, mais glissent par frottement sur ladite voie fixe. De plus, le fait de prévoir une ossature commune à tous les modules nuit, de façon évidente, à la flexibilité de l'installation : en effet, pour une ossature déterminée, la flexibilité se limite à l'interchangeabilité des postes, puisqu'il ne permet pas de modifier le nombre desdits postes.Regarding the known installation, mentioned above, it should be noted that the method of supporting and driving the pallets is relatively complicated and costly in energy, since the said pallets are not supported by an endless conveyor, but slide by friction on said fixed track. In addition, the fact of providing a frame common to all the modules obviously harms the flexibility of the installation: indeed, for a determined frame, the flexibility is limited to the interchangeability of the stations, since does not allow the number of said posts to be changed.
L'objet de la présente invention est de réaliser un dispositif pour le transport libre de pièces présentant une flexibilité totale, tout en profitant des avantages des transporteurs sans fin.The object of the present invention is to provide a device for the free transport of parts having total flexibility, while taking advantage of the advantages of endless transporters.
A cette fin, selon l'invention, le dispositif destiné au transport de pièces devant être adressées successivement à une pluralité de postes de travail et comportant un transporteur sans fin qui défile devant lesdits postes de travail et entrai ne par friction des palettes porte-pièces reposant à plat sur ledit transporteur, ce dispositif présentant une structure modulaire, est remarquable en ce que chaque module qui le constitue comporte un châssis, un transporteur sans fin élémentaire, et des moyens de connexion en énergie et en ce que lesdits modules sont assemblables les uns à la suite des autres, de façon que les châssis de deux modules consécutifs soient mécaniquement solidaires l'un de l'autre, que les transporteurs sans fin élémentaires de deux modules consécutifs soient disposés à la suite l'un de l'autre et que chaque module constitue pour le suivant un maillon de la connexion à une source d'énergie.To this end, according to the invention, the device intended for the transport of parts to be addressed successively to a plurality of work stations and comprising an endless conveyor which passes in front of said work stations and entrains frictionless workpiece pallets resting flat on said conveyor, this device having a modular structure, is remarkable in that each module which constitutes it comprises a chassis, an elementary endless conveyor, and means of energy connection and in that said modules are assembled one after the other, so that the chassis of two consecutive modules are mechanically integral with one another, so that the elementary endless conveyors of two consecutive modules are arranged one after the other and that each module constitutes for the next one a link in the connection to an energy source.
Ainsi, selon l'invention, ledit dispositif de transport est constitué d'une pluralité de modules dont les transporteurs sans fin élémentaires forment, par leur mise bout à bout, ledit transporteur sans fin. Ces modules sont parfaitement interchangeables et leur nombre peut être choisi à volonté, puisqu'il suffit pour former ledit dispositif d'assembler mécaniquement et de relier énergétiquement (par lesdits moyens de connexion en énergie) un module au module précédent. On obtient donc la grande flexibilité recherchée.Thus, according to the invention, said transport device consists of a plurality of modules, the elementary endless conveyors of which form, by their end-to-end placement, said endless conveyor. These modules are perfectly interchangeable and their number can be chosen at will, since it suffices to form said device to mechanically assemble and energetically connect (by said energy connection means) a module to the previous module. The great flexibility sought is therefore obtained.
Bien entendu, la suite desdits modules peut former un alignement rectiligne. Cependant, il est souvent avantageux que le dispositif de transport présente, de manière connue, la forme d'un anneau horizontal sans fin. Dans ce cas, le dispositif selon l'invention peut comporter des modules à transporteur sans fin élémentaire rectiligne pour constituer deux alignements parallèles et des modules à transporteur sans fin élémentaire curviligne pour constituer des raccords aux deux extremités des deux alignements parallèles. Il est alors indispensable que lesdits transporteurs sans fin élémentaires curvilignes soient formées par des chaînes à maillons plats articulés pouvant aussi bien virer à plat autour d'un axe orthogonal au plan du transporteur que s'enrouler autour d'un axe parallèle audit plan.Of course, the series of said modules can form a rectilinear alignment. However, it is often advantageous that the transport device has, in known manner, the shape of an endless horizontal ring. In this case, the device according to the invention may comprise modules with a straight elementary endless conveyor to form two parallel alignments and modules with a curved straight elementary conveyor to form connections at the two ends of the two parallel alignments. It is then essential that said curvilinear elementary endless conveyors are formed by chains with articulated flat links which can both turn flat around an axis orthogonal to the plane of the conveyor and wind around an axis parallel to said plane.
Il existe sur le marché des chaînes de ce type, par exemple celles fabriquées par la Société SKF et connues sous la dénomination commerciale XHTP5.There are chains of this type on the market, for example those manufactured by the company SKF and known under the trade name XHTP5.
De façon connue, le dispositif de transport selon lvinven- tion peut comporter au moins un convoyeur sans fin d'alimentation des postes de travail en porte-pièces, ledit convoyeur étant monté en dérivation sur ledit transporteur sans fin pour pouvoir etre alimenté en porte-pièces à partir dudit transporteur sans fin, alimenter lesdits postes de travail en porte-pièces et restituer lesdits porte-pièces audit transporteur.Dans ce cas, avantageusement, au moins certains desdits modules comportent, en plus dudit transporteur sans fin élémentaire, un convoyeur sans fin élémentaire, susceptible de transporter lesdits porte-pièces par friction, des moyens de transfert par coulissement desdits porte-pièces entre lesdits transporteur et convoyeur sans fin élémentaires, ainsi que des moyens d'arrêt desdits porte-pièces sur le convoyeur sans fin élémentaire et/ou sur le transporteur sans fin élémentaire.In known manner, the transport device according to the invention may comprise at least one endless conveyor for supplying workstations with workpieces, said conveyor being mounted in bypass on said endless conveyor in order to be able to be supplied with parts from said endless conveyor, supplying said workstations with workpiece carriers and returning said workpiece carriers to said conveyor. In this case, advantageously, at least some of said modules comprise, in addition to said elementary endless conveyor, a conveyor without elementary end, capable of transporting said workpiece carriers by friction, means of sliding transfer of said workpiece carriers between said elementary conveyor and endless conveyor, as well as means of stopping said workpiece carriers on the elementary endless conveyor and / or on the basic endless transporter.

Le dispositif selon l'invention, montré schématiquement sur la figure 1 est destiné au transport de pièces devant être successivement adressées à une pluralité de postes de travail. Dans le schéma de la figure 1, chacun de ces postes de travail est constitué par un module 1, pourvu d'un châssis 2 et d'un transporteur sans fin élémentaire 3. Les modules 1 sont agencés en deux alignements parallèles, dont les deux extrêmités sont reliées #par des modules de raccord 4, pourvus chacun d'un châssis 5 et d'un transporteur sans fin courbe 6.The device according to the invention, shown schematically in Figure 1 is intended for the transport of parts to be successively addressed to a plurality of workstations. In the diagram of Figure 1, each of these workstations consists of a module 1, provided with a chassis 2 and an elementary endless conveyor 3. The modules 1 are arranged in two parallel alignments, the two of which ends are connected #by connection modules 4, each provided with a chassis 5 and a curved endless conveyor 6.
Les châssis 2 des modules 1 de chaque alignement sont fixés les uns aux autres par des moyens mécaniques 7, de façon que les différents transporteurs élémentaires 3, qui sont rectilignes, soient alignés. Les transporteurs élémentaires 3 des modules 1 des deux alignements forment donc deux portions rectilignes parallèles d'un transporteur unique.The chassis 2 of the modules 1 of each alignment are fixed to each other by mechanical means 7, so that the various elementary conveyors 3, which are rectilinear, are aligned. The elementary conveyors 3 of the modules 1 of the two alignments therefore form two parallel rectilinear portions of a single conveyor.
Ces deux portions rectilignes de transporteur sont reliées l'une à l'autre par les transporteurs courbes 6 des modules 4, dont les châssis 5 sont mécaniquement fixés aux châssis 2 des modules 1 adjacents.These two rectilinear transporter portions are connected to each other by the curved conveyors 6 of the modules 4, the chassis 5 of which are mechanically fixed to the chassis 2 of the adjacent modules 1.
Au moins les transporteurs sans fin courbes 6 sont constitués d'une chaîne à maillons pouvant à la fois virer dans son plan et parallèlement à son plan. Une telle chaîne est par exemple du type mentionné ci-dessus. At least the curved endless conveyors 6 consist of a link chain which can both turn in its plane and parallel to its plane. Such a chain is for example of the type mentioned above.
Chaque module ou poste de travail 1 ou 4 comporte des moyens d'entraînement (non représentés) de son transporteur 3 ou 6, ainsi que tout moyen d'actionnement désiré (également non représenté). Ces différents moyens d'entraînement ou d'actionnement sont alimentés en énergie à partir d'une boîte de raccordement 7, par l'intermédiaire d'une liaison 8. Chaque boîte de raccordement 7 reçoit elle-même l'énergie de la boîte de raccordement 7 du module précédent, par l'intermédiaire d'une liaison 9.Each module or work station 1 or 4 has drive means (not shown) for its conveyor 3 or 6, as well as any desired actuation means (also not shown). These different drive or actuation means are supplied with energy from a connection box 7, via a connection 8. Each connection box 7 itself receives the energy from the connection box. connection 7 of the previous module, via a link 9.
On voit ainsi que l'ensemble des transporteurs sans fin 3 et 6 forment un transporteur sans fin unique qui défile devant les différents postes de travail 1-et peut entraîner par friction des palettes porte-pièces, par exemple du type de celle montrée par la figure 5, reposant à plat sur ledit transporteur.It can thus be seen that all of the endless conveyors 3 and 6 form a single endless conveyor which passes in front of the different work stations 1 - and can frictionally carry workpiece pallets, for example of the type shown by the Figure 5, resting flat on said conveyor.
Chacun de ces postes de travail peut être manuel ou automatique et comporter des moyens connus pour arrêter l'avance desdites palettes porte-pièces.Each of these workstations can be manual or automatic and include known means for stopping the advance of said workpiece pallets.
Sur la vue en plan schématique de la figure 2, on a représenté une variante de réalisation du dispositif de la figure 1, dans lequel chaque module 1, en plus du transporteur sans fin élémentaire 3, comporte un convoyeur sans fin élémentaire 10, parallèle à ce dernier. De plus, chaque module 1 comporte des moyens il tels que des vérins, pour transférer par glissement (par traction ou poussée), les porte-pièces du transporteur 3 au convoyeur 10 et viceversa.In the schematic plan view of Figure 2, there is shown an alternative embodiment of the device of Figure 1, in which each module 1, in addition to the elementary endless conveyor 3, comprises an elementary endless conveyor 10, parallel to this last. In addition, each module 1 comprises means il such as jacks, for transferring by sliding (by pulling or pushing), the workpiece carriers from the conveyor 3 to the conveyor 10 and vice versa.
Les convoyeurs élémentaires 10 sont alignés les uns avec les autres et défilent dans le même sens que les transporteurs élémentaires 3. On conçoit donc aisément que, grâce aux moyens 11, il soit possible de faire passer les porte-pièces des transporteurs 3 aux convoyeurs 10 en fonction des opérations à effectuer sur les pièces portées par lesdits porte-pièces. The elementary conveyors 10 are aligned with each other and run in the same direction as the elementary conveyors 3. It is therefore easily understood that, by means of the means 11, it is possible to pass the workpiece carriers of the conveyors 3 to the conveyors 10 depending on the operations to be performed on the parts carried by said workpiece carriers.
De plus, le long desdits transporteur 3 et convoyeur 10 sont disposés des dispositifs d'arrêt 12 à doigts rétractables, par exemple pour arrêter les porte-pièces en vue- de leur transfert entre transporteurs 3 et convoyeurs il, entre transporteurs 3 consécutifs, entre convoyeurs 11 consécutifs ou bien encore en vue d'une opération à effectuer sur lesdites pièces.In addition, along said conveyor 3 and conveyor 10 are arranged stop devices 12 with retractable fingers, for example for stopping the workpiece carriers with a view to their transfer between conveyors 3 and it conveyors, between consecutive conveyors 3, between conveyors 11 consecutive or even for an operation to be performed on said parts.
Les figures 3 et 4 montrent, respectivement en perspective et en vue de coté, un mode de réalisation pratique des modules 1 du dispositif de la figure 2. On y retrouve le châssis 2 pouvant être solidarisé du châssis 2 d'un autre module 1 ou du châssis 5 d'un module 4 grâce -à de-s trous 13 pouvant être traversés par des boulons de liaison (non représentés).Figures 3 and 4 show, respectively in perspective and in side view, a practical embodiment of the modules 1 of the device of Figure 2. There is the chassis 2 can be secured to the chassis 2 of another module 1 or of the chassis 5 of a module 4 thanks to the holes 13 which can be crossed by connecting bolts (not shown).
Le transporteur élémentaire 3 et le convoyeur élémentaire 10 sont au même niveau horizontal et, en regard des moyens 11 de poussée et/ou de traction des palettes porte-pièces, ils sont reliés par des plages 14 à niveau de façon que lesdites palettes puissent passer de l'un à l'autres par glissement sur lesdites plages. Le module 1 est enfermé dans un capot 15 pourvu d'ouvertures 16 pour le passage de l'organe actif (palette de poussée ou crochet de traction) des moyens 11.The elementary conveyor 3 and the elementary conveyor 10 are at the same horizontal level and, opposite the means 11 for pushing and / or pulling the workpiece pallets, they are connected by tracks 14 level so that said pallets can pass from one to the other by sliding on said areas. The module 1 is enclosed in a cover 15 provided with openings 16 for the passage of the active member (pushing pallet or traction hook) of the means 11.
Ce capot 15 comporte également des ouvertures 17 pour le passage des doigts d'arrêt des dispositifs 12 et une ouverture 18 pour le passage d'un dispositif de centrage des palettes porte-pièces lorsque celles-ci sont arrêtées dans leur position de travail.This cover 15 also includes openings 17 for the passage of the stop fingers of the devices 12 and an opening 18 for the passage of a device for centering the workpiece pallets when they are stopped in their working position.
Le module 1 comporte un coffre 19 dans lequel sont enfermés des moyens énergétiques susceptibles d'actionner les organes moteurs du transporteur 3, du convoyeur 10 des moyens de transfert 11, des dispositifs d'arrêt 12, du dispositif de centrage, et de manière plus générale de tous les moteurs et actuateurs portés par ledit module 1. Une ouverture 20 dans le coffre 19 permet le passage des différentes liaisons énergétiques 9.The module 1 comprises a box 19 in which are energized means capable of actuating the drive members of the conveyor 3, of the conveyor 10 of the transfer means 11, of the stop devices 12, of the centering device, and more general of all the motors and actuators carried by said module 1. An opening 20 in the trunk 19 allows the passage of the various energy connections 9.
Le module 1 montré par les figures 3 et 4 présente la forme générale d'un bureau, afin de constituer un poste de travail manuel confortable pour l'opérateur.The module 1 shown in FIGS. 3 and 4 presents the general shape of a desk, in order to constitute a comfortable manual work station for the operator.
Par les transporteurs 3 et convoyeurs 10, peuvent être transportées par friction des palettes porte-pièces 21, dont un exemple est montré en perspective du dessous sur la figure 5. Une telle palette 21 peut comporter une embase 22 supportant une plaque de support 23, percées d'une ouverture centrale 24 permettant le travail des pièces par le dessous.By the conveyors 3 and the conveyors 10, workpiece pallets 21 can be transported by friction. An example is shown in perspective from below in FIG. 5. Such a pallet 21 can include a base 22 supporting a support plate 23, pierced with a central opening 24 allowing the work of the parts from below.
Parallèlement aux transporteurs 3 et convoyeurs 10, les palettes 21 comportent un barreau magnétique longitudinal 25, utilisé pour indiquer la présence d'une palette à des détecteurs (non représentés)- disposés le long du trajet suivi par ladite palette. La palette 21 comporte également des plots magnétiques 26 pour le codage du numéro de palette et au moins un plot magnétique 27 pour le positionnement des palettes. Parallel to the conveyors 3 and conveyors 10, the pallets 21 include a longitudinal magnetic bar 25, used to indicate the presence of a pallet to detectors (not shown) - arranged along the path followed by said pallet. The pallet 21 also includes magnetic pads 26 for coding the pallet number and at least one magnetic pad 27 for positioning the pallets.
Latéralement, c'est-à-dire parallèlement à la direction longitudinale des transporteurs 3 et convoyeurs 10, chaque palette 21 comporte une rainure de préhension 28 (pour les dispositifs de traction 11), ainsi que des encoches de butée d'arrêt 29 pour la coopération avec les dispositifs d'arrêt 12 et une encoche d'indexage 30 pour le dispositif de centrage, dont l'organe mobile passe à travers l'ouverture 18. Laterally, that is to say parallel to the longitudinal direction of the conveyors 3 and conveyors 10, each pallet 21 has a gripping groove 28 (for the traction devices 11), as well as stop stop notches 29 for cooperation with the stop devices 12 and an indexing notch 30 for the centering device, the movable member of which passes through the opening 18.
