Description

DISPOSITIF DE RETOURNEMENT  REVERSING DEVICE
L'invention se situe dans le domaine des dispositifs de retournement de pièces lourdes, permettant notamment de retourner une telle pièce de 360 degrés autour d'un axe horizontal. The invention lies in the field of devices for reversing heavy parts, in particular for turning such a piece 360 degrees around a horizontal axis.
De tels dispositifs existent sur le marché. La société SEFAC fournit notamment des colonnes mobiles de retournement. La déposante fournit des retourneurs de roues, notamment pour les roues de trains, et des vireurs pneumatiques permettant le basculement de pièces lourdes de 50 degrés. Il existe aussi des vireurs pneumatiques permettant un basculement de 70 degrés et des vireurs électromécaniques permettant un retournement de 360 degrés. Such devices exist on the market. The company SEFAC provides mobile columns for reversing. The applicant supplies wheel turners, in particular for the wheels of trains, and pneumatic toners allowing the tilting of heavy parts of 50 degrees. There are also pneumatic toners for 70 degrees tilting and electromechanical tugs for 360 degree rollover.
Ces différents dispositifs comportent plusieurs limites. These different devices have several limitations.
Ainsi, les dispositifs électriques à transmission mécanique présentent de nombreux inconvénients : Thus, electrical devices with mechanical transmission have many disadvantages:
- ils nécessitent une grande précision de mise en place, en particulier pour des charges de grandes dimensions et lourdes ce qui implique un temps de mise en place élevé ;  - They require a high accuracy of implementation, especially for large loads and heavy which implies a high implementation time;
- ils demandent, pour être tolérants vis-à-vis d'excentrations, un dimensionnement large des moteurs ;  they require, in order to be tolerant towards offsets, a large dimensioning of the motors;
- ils demandent des dispositifs complexes, par exemple frein magnétique, crémaillère antichute, pour assurer la sécurité du fonctionnement ; - ils demandent des mesures de protection spéciales contre les risques électriques, y compris ceux d'alimentation, en particulier en atmosphère explosive ; - they require complex devices, such as magnetic brake, fall arrest rack, to ensure the safety of operation; - they require special protection measures against electrical hazards, including those of power supply, especially in explosive atmospheres;
- ils sont sensibles à l'environnement, par exemple en cas de sablage, peinture ou grenaillage de la pièce ;  - they are sensitive to the environment, for example in the case of sanding, painting or shot blasting of the piece;
- ils ont un nombre de composants élevé ;  they have a high number of components;
- en maintenance ils nécessitent :  - in maintenance they require:
o une gestion en magasin de nombreuses références ; o un personnel multi-compétent qualifié ; et,  o store management of numerous references; o qualified multi-skilled staff; and,
- si, pour des questions d'ergonomie, il est nécessaire d'élever la charge, ces systèmes demandent plusieurs moteurs, des dispositifs mécaniques supplémentaires, notamment des vis, et une synchronisation de l'ensemble pour ne pas forcer sur ces mêmes dispositifs. La société demanderesse a développé une solution pneumatique permettant un basculement de plus ou moins 70 degrés. Ce système élimine les inconvénients des dispositifs électriques ci-dessus. Il est, en particulier, très tolérant au niveau de la précision de mise en place des pièces. Il est aussi très tolérant quant à la position du centre de gravité de la pièce par rapport à l'axe de basculement. En outre, les temps de basculement sont courts. Cette solution utilise des vérins à soufflets, peu coûteux et faciles d'entretien, même pour une utilisation en atmosphère explosive. Toutefois ce système est limité à un angle de basculement de plus ou moins 70 degrés. Le but de l'invention est de proposer un dispositif de retournement d'une pièce, permettant un retournement horizontal de 360 degrés  - If, for ergonomic reasons, it is necessary to raise the load, these systems require several motors, additional mechanical devices, including screws, and a synchronization of the whole not to force on these same devices. The plaintiff company has developed a pneumatic solution allowing a tilting of plus or minus 70 degrees. This system eliminates the disadvantages of the above electrical devices. It is, in particular, very tolerant in terms of the precision of placing parts. It is also very tolerant as to the position of the center of gravity of the part with respect to the axis of tilting. In addition, the switching times are short. This solution uses bellows jacks, which are inexpensive and easy to maintain, even for use in explosive atmospheres. However this system is limited to a tilt angle of plus or minus 70 degrees. The object of the invention is to provide a device for reversing a workpiece, allowing a 360 degree horizontal turnaround

La figure 1 illustre un système 1 selon l'invention prévu pour retourner horizontalement une pièce 2. Le système 1 comprend deux dispositifs 3 disposés en vis-à-vis l'un de l'autre, chacun portant une extrémité respective de la pièce 2. Le dispositif 3 le plus à gauche sur la figure 1 est représentée partiellement coupé, de sorte que l'on en voit l'intérieur. Les deux dispositifs 3 sont identiques entre eux. FIG. 1 illustrates a system 1 according to the invention intended for horizontally returning a part 2. The system 1 comprises two devices 3 arranged facing each other, each carrying a respective end of the part 2 The leftmost device 3 in Fig. 1 is shown partially cut away so that the inside is seen. The two devices 3 are identical to each other.
Chaque dispositif de retournement comprend : Each turning device comprises:
- un châssis ; ce châssis a la forme d'une colonne 5 creuse, de section horizontale sensiblement carrée, et comprend une embase 6 servant d'appui au sol pour le dispositif ;  - a chassis ; this frame has the form of a hollow column, of substantially square horizontal section, and comprises a base 6 serving as a ground support for the device;
- un chariot 7, monté coulissant verticalement à l'intérieur de la colonne 5 ;  a carriage 7 mounted vertically sliding inside the column 5;
- un vérin pneumatique à soufflet 8, disposé dans la colonne et sous le chariot pour le faire coulisser ;  - A pneumatic cylinder bellows 8, arranged in the column and under the carriage to slide it;
- des moyens de préhension 9 qui comprennent un mandrin 10 destiné à maintenir la pièce 2. Les moyens de préhension comprennent un arbre horizontal 12 qui traverse la colonne 5. Dans le système de la figure 1, les moyens de préhension 9 sont disposés en vis-à-vis des moyens de préhension de l'autre dispositif. La colonne étant disposée au-delà des moyens de préhension relativement à cet autre dispositif. Le chariot forme un palier 11 pour la rotation de l'arbre 12 autour d'un axe de basculement X12 horizontal ; ainsi, l'arbre et le palier forment ensemble une liaison pivot. Une fenêtre intérieure 13 permet le passage de l'arbre 12 au travers d'une face intérieure de la colonne, c'est-à-dire d'une face en vis-à- vis de la même face de l'autre dispositif. Une fenêtre extérieure 14 permet le passage de l'arbre 12 au travers d'une face extérieure 15 de la colonne 5, c'est-à-dire d'une face opposée à la face intérieure 44. Les fenêtres intérieure et extérieure ont sensiblement les mêmes dimensions ; elles sont oblongues, allongées verticalement, de sorte qu'elles permettent la montée et la descente de l'arbre 12 en même temps que celle du chariot 7. gripping means 9 which comprise a mandrel 10 intended to hold the part 2. The gripping means comprise a horizontal shaft 12 which passes through the column 5. In the system of FIG. 1, the gripping means 9 are disposed vis-à-vis the gripping means of the other device. The column being disposed beyond the gripping means relative to this other device. The carriage forms a bearing 11 for the rotation of the shaft 12 about a horizontal axis X12 tilt; thus, the shaft and the bearing together form a pivot connection. An inner window 13 allows the passage of the shaft 12 through an inner face of the column, that is to say one face vis-à-vis the same face of the other device. An outer window 14 allows the passage of the shaft 12 through an outer face 15 of the column 5, that is to say a face opposite to the inner face 44. The inner and outer windows have substantially the same dimensions; they are oblong, elongated vertically, so that they allow the raising and lowering of the shaft 12 at the same time as that of the carriage 7.
Une extrémité extérieure de l'arbre 12 porte une platine d'entraînement 17 qui s'étend transversalement à l'axe de basculement X12. Ainsi, l'arbre 12 permet de solidariser la platine d'entraînement 17 avec le mandrin 10 correspondant. Dans l'exemple illustré la platine 17 est une tôle carrée. Au voisinage de chaque angle de la platine, la platine comprend un ancrage A-D, un premier ancrage A est le plus haut et en arrière, un deuxième ancrage B est le plus bas et en arrière, un troisième ancrage C est le plus bas et en avant et le quatrième ancrage D est le plus haut et en avant. Le dispositif de retournement 3 comprend en outre une bielle 18 montée en rotation autour d'un axe de bielle horizontal X18, parallèle à l'axe de basculement. L'axe de bielle XI 8 est fixe relativement à la colonne 5, dans un même plan vertical que l'axe de basculement XI 2. Une extrémité libre 19 de la bielle 18 est prévue pour être fixée de façon amovible sur l'un quelconque des ancrages A-D de la platine. Le dispositif 3 comprend aussi une butée haute 21, disposée de sorte que dans la position haute, illustrée aux figures 3 à 5, la platine vient en butée contre la butée 21. An outer end of the shaft 12 carries a drive plate 17 which extends transversely to the tilting axis X12. Thus, the shaft 12 makes it possible to secure the drive plate 17 with the corresponding mandrel 10. In the example illustrated, the plate 17 is a square plate. In the vicinity of each corner of the plate, the plate comprises an anchorage AD, a first anchorage A is the highest and back, a second anchorage B is the lowest and back, a third anchorage C is the lowest and in before and the fourth anchorage D is the highest and forward. The turning device 3 further comprises a rod 18 rotatably mounted about a horizontal rod axis X18, parallel to the tilting axis. The connecting rod axis XI 8 is fixed relative to the column 5, in the same vertical plane as the tilting axis XI 2. A free end 19 of the connecting rod 18 is provided to be removably attached to any one anchors AD of the plate. The device 3 also comprises a high stop 21, arranged so that in the high position, illustrated in Figures 3 to 5, the plate abuts against the stop 21.
Dans la position basse du dispositif, illustrée à la figure 1, la platine 17 a deux de ses côtés qui sont horizontaux, de sorte que le premier ancrage A et le quatrième ancrage D de son côté le plus haut sont également accessibles pour y fixer l'extrémité 19 de la bielle 18. A la figure 1, la bielle est fixée au premier ancrage A, le plus haut et en arrière ; le dispositif de droite a une disposition symétrique à celui de gauche. In the lower position of the device, illustrated in Figure 1, the plate 17 has two of its sides which are horizontal, so that the first anchorage A and the fourth anchor D on its highest side are also accessible to fix the l end 19 of the connecting rod 18. In Figure 1, the connecting rod is fixed to the first anchorage A, the highest and back; the device on the right has a symmetrical layout to the one on the left.
Nous allons maintenant décrire le fonctionnement du dispositif, et donc du système, en prenant comme position initiale la position basse illustrée à la figure 1. Afin de retourner la pièce 2, on gonfle le vérin 8, de sorte que le chariot 7 se déplace de bas en haut dans la colonne 5, entraînant l'arbre 12 et la platine 17. Le premier ancrage A de la platine, décalé vers l'arrière relativement au plan vertical commun aux axes de retournement X12 et de bielle XI 8, est retenu par la bielle 18 de sorte qu'il crée un moment sur la platine 17, autour de l'axe de basculement. La platine est donc entraînée dans une rotation selon R autour de l'axe de basculement XI 2. Le mandrin 10 étant rigidement lié à la platine 17 par l'arbre 12, il subit la même rotation R qu'elle transmet à la pièce 2, qui y est fixée. Ainsi, à mesure où le chariot 7 s'élève dans la colonne 5, la pièce 2 bascule autour de l'axe de basculement X12. La figure 2 illustre une position intermédiaire entre la position basse et la position haute, dans laquelle le basculement a atteint environ 45 degrés. We will now describe the operation of the device, and therefore of the system, taking as initial position the lower position illustrated in Figure 1. In order to return the part 2, the cylinder 8 is inflated, so that the carriage 7 moves from bottom up in the column 5, driving the shaft 12 and the plate 17. The first anchorage A of the plate, shifted rearwardly relative to the vertical plane common to the X12 reversing axes and connecting rod XI 8, is retained by the rod 18 so that it creates a moment on the plate 17, around the tilting axis. The plate is thus driven in a rotation along R about the tilting axis XI 2. The mandrel 10 being rigidly connected to the plate 17 by the shaft 12, it undergoes the same rotation R that it transmits to the part 2 which is fixed there. Thus, as the carriage 7 rises in the column 5, the part 2 tilts around the tilting axis X12. Figure 2 illustrates an intermediate position between the low position and the high position, in which the tilting has reached about 45 degrees.
La figure 3 illustre la position haute. Un côté de la platine 17, portant le troisième ancrage C et le quatrième ancrage D, initialement vertical, est maintenant horizontal et calé contre la butée haute 21. Le basculement a atteint 90 degrés autour de l'axe de basculement X12. Le premier ancrage A est alors le plus bas et en arrière de la platine 17 et le deuxième ancrage B est le plus bas et en avant, à la même distance de l'axe de bielle XI 8 que le premier ancrage A. Dans cette position, la butée 21 permet de verrouiller la position de la charge 2 sous la pression du vérin 8. La bielle 18 n'est plus contrainte et peut donc être détachée de l'ancrage A. Figure 3 illustrates the high position. One side of the plate 17, carrying the third anchor C and the fourth anchorage D, initially vertical, is now horizontal and wedged against the upper stop 21. The tilting has reached 90 degrees around the tilting axis X12. The first A anchor is then the lowest and back of the plate 17 and the second anchorage B is the lowest and forward, at the same distance from the connecting rod axis XI 8 as the first anchorage A. In this position, the stop 21 allows to lock the position of the load 2 under the pressure of the cylinder 8. The rod 18 is no longer constrained and can be detached from the anchor A.
Pour poursuivre le basculement au-delà de 90 degrés, on détache la bielle 18 du premier ancrage A, comme illustré à la figure 4, pour le fixer au deuxième ancrage B, comme illustré à la figure 5. A partir de cette position haute, on dégonfle le vérin 8, de sorte que le chariot 7 se déplace de haut en bas dans la colonne 5, entraînant l'arbre 12 et la platine 17. Le deuxième ancrage B de la platine, décalé vers l'avant relativement au plan vertical commun aux axes de retournement X12 et de bielle X18, est retenu par la bielle 18 de sorte qu'il crée un moment sur la platine 17, autour de l'axe de basculement. La platine est donc entraînée dans une nouvelle rotation selon R autour de l'axe de basculement X12. Ainsi, à mesure où le chariot 7 descend dans la colonne 5, la pièce 2 continue à basculer autour de l'axe de basculement X12, toujours selon R. La figure 6 illustre une position intermédiaire entre la position haute et la position basse, dans laquelle le basculement a atteint environ 135 degrés, mesuré à partir de la position initiale de la figure 1. To continue the tilting beyond 90 degrees, the rod 18 is detached from the first anchorage A, as shown in FIG. 4, to fix it to the second anchorage B, as illustrated in FIG. 5. From this high position, the cylinder 8 is deflated, so that the carriage 7 moves up and down in the column 5, driving the shaft 12 and the plate 17. The second anchorage B of the plate, shifted forwards relative to the vertical plane common to X12 overturning axes and connecting rod X18, is retained by the connecting rod 18 so that it creates a moment on the plate 17, around the tilting axis. The plate is thus driven in a new rotation along R about the X12 tilting axis. Thus, as the carriage 7 descends into the column 5, the part 2 continues to swing around the tilting axis X12, again according to R. FIG. 6 illustrates an intermediate position between the high position and the low position, in which the tilting has reached about 135 degrees, measured from the initial position of Figure 1.
La figure 7 illustre la nouvelle position basse. Le basculement a atteint 180 degrés autour de l'axe de basculement XI 2. Le premier ancrage A est alors le plus bas et en avant de la platine 17. Figure 7 illustrates the new low position. The tilting has reached 180 degrees around the tilting axis XI 2. The first anchorage A is then the lowest and in front of the plate 17.
On peut poursuivre le basculement indéfiniment. Ainsi, pour poursuivre le basculement jusqu'à 180 degrés, il convient de fixer d'abord la bielle au troisième ancrage C et de faire remonter le chariot jusqu'à sa position haute, puis, de fixer la bielle 18 au quatrième ancrage D et de faire redescendre le chariot 7 à sa position basse. A partir de la position de la figure 1, il est aussi possible de faire basculer la pièce 2 dans un sens inverse à la rotation R précédemment illustrée, en fixant la bielle 18 d'abord au quatrième ancrage D puis successivement au troisième C, au deuxième B et au premier A. We can continue the change indefinitely. Thus, to continue the tilting up to 180 degrees, it is necessary to first fix the connecting rod to the third anchor C and to raise the carriage to its upper position, then to attach the connecting rod 18 to the fourth anchorage D and to lower the carriage 7 to its lower position. From the position of Figure 1, it is also possible to tilt the part 2 in a direction opposite to the rotation R previously illustrated, by fixing the connecting rod 18 first to the fourth anchorage D and then successively to the third C, the second B and first A.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits. Of course, the invention is not limited to the examples which have just been described.
Ainsi, dans l'exemple illustré, la rotation est indexable tous les 90 degrés. Une rotation à 180 degrés est réalisée pour une sortie et une rentrée du vérin 8. Une rotation à 360 degrés est réalisée pour 2 sorties et 2 rentrées du vérin. Une indexation tous les 60 degrés peut être obtenue par une platine hexagonale portant 6 ancrages. D'autres types d'indexations peuvent être obtenus dans un nombre différent d'ancrages. Pour des charges longues, le système fonctionne avec deux dispositifs de retournement, c'est-à-dire deux colonnes jumelées en vis-à-vis, comme précédemment illustré. Les deux dispositifs étant avantageusement indépendants l'entraxe des colonnes peut être réglé pour s'adapter à la longueur de la pièce à basculer. Thus, in the illustrated example, the rotation is indexable every 90 degrees. A 180 degree rotation is performed for an output and retraction of the cylinder 8. A 360 degree rotation is performed for 2 outputs and 2 cylinder returns. Indexing every 60 degrees can be achieved by a hexagonal plate carrying 6 anchors. Other types of indexing can be obtained in a different number of anchors. For long loads, the system operates with two reversing devices, that is to say two twin columns vis-à-vis, as previously illustrated. The two devices being advantageously independent, the distance between the columns can be adjusted to suit the length of the part to be tilted.
On peut aussi utiliser un seul dispositif, c'est-à-dire en mono-colonne, chargé en porte à faux pour des charges suffisamment compactes ou légères. It is also possible to use a single device, that is to say one-column, loaded cantilever for sufficiently compact or light loads.
Les avantages d'un dispositif selon l'invention sont multiples et notamment : The advantages of a device according to the invention are multiple and in particular:
- facilité de mise en place de la charge, notamment en utilisant pour les moyens de préhension des mors adaptables et ouvrables dans différentes directions ;  - ease of installation of the load, in particular by using for gripping means jaws adaptable and open in different directions;
- tolérance aux défauts de centrage et d'équilibrage ;  - tolerance to centering and balancing faults;
- facilité pour se procurer une source d'énergie pneumatique.  - easy to get a source of pneumatic energy.
- des vérins à soufflets peu onéreux par rapport à leurs homologues hydrauliques ou électriques ; peu de pièces d'usure et maintenance facilitée ; - bellows cylinders inexpensive compared to their hydraulic or electric counterparts; few wear parts and easy maintenance;
le principe d'élévation-rotation permet de sécuriser la manœuvre même en cas de rupture pneumatique ; the principle of elevation-rotation allows to secure the maneuver even in case of pneumatic rupture;
compatibilité avec une utilisation en milieu explosif (ATEX). compatibility with use in an explosive environment (ATEX).
