Description

La présente invention concerne des perfectionnements pour les installations de traitement de surface de pièces métalliques. Elle est plus particulièrement relative aux supports pour pièces cylindriques destinées à être immergées dans des bains de phosphatation, de brillantage, de satinage, d'anodisation ou autres. Elle concerne aussi l'installation utilisant les supports.The present invention relates to improvements for installations for treating the surface of metal parts. It relates more particularly to supports for cylindrical parts intended to be immersed in phosphating, brightening, satin-finishing, anodizing or other baths. It also concerns the installation using the supports.

Dans le traitement de surface des pièces métalliques, qu'il soit chimique ou électrolytique, tel que le brillantage ou l'anodisation des pièces en aluminium, celles-ci doivent être immergées dans un bain liquide de traitement comme de l'acide phosphorique ou de l'acide sulfurique et ensuite immergées dans un bain de rinçage.In the surface treatment of metal parts, whether chemical or electrolytic, such as the polishing or anodizing of aluminum parts, these must be immersed in a liquid treatment bath such as phosphoric acid or sulfuric acid and then immersed in a rinsing bath.

Le problème de retenue des pièces lors de leur transport d'un poste de traitement à un autre, et de retenue dans les bains de traitement et de rinçage se pose. En effet, les pièces doivent être retenues de façon sûre afin de ne pas tomber lors de leur manipulation. Par ailleurs, dans le cas de traitement de type électrolytique, le contact électrique entre le support et la pièce doit être assuré de manière fiable.The problem of retaining parts when they are transported from one treatment station to another, and of retaining them in the treatment and rinsing baths arises. Indeed, the parts must be securely retained so as not to fall during their handling. Furthermore, in the case of electrolytic type treatment, the electrical contact between the support and the part must be assured reliably.

Ainsi, le dispositif pour retenir des pièces métalliques de forme tubulaire destinées à subir un traitement de surface du type à voie chimique ou électrolytique, selon l'invention, est caractérisé en ce qu'il est constitué par au moins un support qui comprend deux pattes déformables sensiblement parallèles et qui sont sollicitées en écartement par des moyens élastiques, ledit support étant destiné à être disposé dans la cavité de ladite pièce tubulaire à traiter.Thus, the device for retaining metal parts of tubular shape intended to undergo a surface treatment of the chemical or electrolytic type, according to the invention, is characterized in that it is constituted by at least one support which comprises two tabs deformable substantially parallel and which are biased apart by elastic means, said support being intended to be disposed in the cavity of said tubular part to be treated.

Selon une caractéristique complémentaire, le support est une pièce en titane ayant la forme d'un "U", tandis que l'extrémité de chacune des pattes comprend un dégagement central pour former deux pointes de retenue.According to an additional characteristic, the support is a titanium part having the shape of a "U", while the end of each of the legs comprises a central clearance to form two retaining points.

Dans un mode d'exécution préféré, le dispositif comprend une succession de supports montés dans un cadre périphérique en titane pour constituer une cassette de manutention. Ainsi, le cadre périphérique comprend une succession d'ensembles de retenue porte-support, et chaque ensemble de retenue est monobloc et est réalisé en titane pour être formé par une base ayant la forme d'un profilé en forme de "U" dont chacune des parois longitudinales présente une succession de saillies pour former deux à deux les pattes de retenue d'une succession de supports.In a preferred embodiment, the device comprises a succession of supports mounted in a peripheral titanium frame to constitute a handling cassette. Thus, the peripheral frame comprises a succession of support holder retaining assemblies, and each retaining assembly is monobloc and is made of titanium to be formed by a base having the shape of a "U" shaped profile, each of which longitudinal walls has a succession of projections to form two by two the retaining lugs of a succession of supports.

L'invention concerne aussi l'installation destinée à utiliser le dispositif, cette dernière comprenant un bâti portant des moyens de déplacement des moyens d'alimentation, des moyens de mise en place des pièces et des moyens de rapprochement permettant ie rapprochement simultané des pattes de retenue.The invention also relates to the installation intended to use the device, the latter comprising a frame carrying means for moving the supply means, means for positioning the parts and means for bringing together, ie simultaneous bringing together of the tabs of detention.

Les figures 16a, 16b et 16c illustrent comment est réalisé le rapprochement des pattes des supports.Figures 16a, 16b and 16c illustrate how the legs of the supports are brought together.

Les pièces destinées à subir le traitement de brillantage sont, par exemple, des bouchons en aluminium destinés à être utilisés dans les produits cosmétiques ou les parfums.The parts intended to undergo the polishing treatment are, for example, aluminum caps intended for use in cosmetic products or perfumes.

Les figures 1 a 3 illustrent un tel bouchon portant la référence (1) de forme générale tubulaire et comprenant une paroi péripiiérique (2) et une paroi transversale (3) pour former une cavité cylindrique (4) limitée latéralement et périphériquement par la surface interne (5) de la paroi périphérique (2) et la surface transversale interne (6) de la paroi transversale (3).Figures 1 to 3 illustrate such a stopper bearing the reference (1) of generally tubular shape and comprising a peripheral wall (2) and a transverse wall (3) to form a cylindrical cavity (4) limited laterally and peripherally by the internal surface (5) of the peripheral wall (2) and the internal transverse surface (6) of the transverse wall (3).

Cette pièce (1) ainsi définie est destinée à être retenue pour son traitement de surface par un support de pièce (7) qui selon l'invention comprend deux pattes déformables (8a, 8b) sensiblement parallèles qui sont sollicitées en écartement par des moyens élastiques et qui peuvent être rapprochées contre l'action de ces moyens élastiques. Dans un mode d'exécution préféré, chaque support de pièce (7) a la forme d'une pièce en forme de "U" réalisé en matériau métallique élastique. Selon une caractéristique de l'invention, le support en forme de U est réalisé dans un profilé plat en titane et constitue en lui-même ses moyens élastiques par sa propre déformation.This part (1) thus defined is intended to be retained for its surface treatment by a part support (7) which according to the invention comprises two substantially parallel deformable legs (8a, 8b) which are urged apart by elastic means and which can be compared against the action of these elastic means. In a preferred embodiment, each piece support (7) has the shape of a "U" shaped piece made of elastic metallic material. According to a characteristic of the invention, the U-shaped support is produced in a flat titanium profile and constitutes in itself its elastic means by its own deformation.

Ainsi, le support (7) est configuré pour que dans sa position libre (voir figure 4) les deux pattes de retenue (8a, 8b) soient écartées de façon à ce que la distance (d1) entre les deux extrémités (9a, 9b) soit supérieure au diamètre intérieur (d2) de la pièce (1) à retenir, tandis qu'elles peuvent être rapprochées l'une de l'autre par déformation élastique du support, comme cela est illustré en traits fins mixtes.Thus, the support (7) is configured so that in its free position (see Figure 4) the two retaining tabs (8a, 8b) are spaced so that the distance (d1) between the two ends (9a, 9b ) is greater than the internal diameter (d2) of the part (1) to be retained, while they can be brought closer to each other by elastic deformation of the support, as illustrated in thin dashed lines.

Par ailleurs, notons que l'extrémité de chacune des pattes de retenue comprend un dégagement central (10) en forme, par exemple, de "V" formant ainsi deux pointes de retenue (11a, 11b) destinées à s'agripper sur la surface interne (5) de la cavité cylindrique (4) de la pièce à retenir (1).Furthermore, note that the end of each of the retaining tabs includes a central clearance (10) in the form, for example, of "V" thus forming two retaining points (11a, 11b) intended to grip on the surface internal (5) of the cylindrical cavity (4) of the part to be retained (1).

Ainsi (voir figures 7, 8 et 9), pour mettre en place la pièce (1) sur son support (7), il suffit de rapprocher les deux pattes de retenue (8a, 8b) en les sollicitant, par déformation élastique du "U", l'une vers l'autre, par une action F, et placer les deux extrémités (9a, 9b) à une distance (d3) inférieure à la distance initiale (d1), suffisamment faible pour que les deux pattes (8a, 8b) puissent être engagées dans la cavité cylindrique (4) de la pièce (1), comme cela est représenté à la figure 8. La pièce (1) est ensuite engagée complètement sur le support jusqu'à ce que la surface transversale interne (6) soit en appui sur les pointes de retenue (11a, 11b) des deux extrémités (9a, 9b) des pattes de retenue (8a, 8b), comme cela est illustré à la figure 9. Il va de soi qu'il n'est pas nécessaire que la pièce (7) soit engagée complètement car elle peut, en effet. ne l'être que partiellement.Thus (see Figures 7, 8 and 9), to set up the part (1) on its support (7), it suffices to bring the two retaining tabs (8a, 8b) closer together by urging them, by elastic deformation of the " U ", towards each other, by an action F, and place the two ends (9a, 9b) at a distance (d3) less than the initial distance (d1), sufficiently small so that the two legs (8a , 8b) can be engaged in the cylindrical cavity (4) of the part (1), as shown in FIG. 8. The part (1) is then fully engaged on the support until the internal transverse surface (6) either resting on the retaining pins (11a, 11b) of the two ends (9a, 9b) of the retaining tabs (8a, 8b), as illustrated in FIG. 9. It goes without saying that it the part (7) need not be fully engaged as it can, indeed. only be partially so.

Dans un contexte industriel, il n'est, bien entendu, pas question de traiter par voie chimique ou électrolytique chaque pièce de façon unitaire et indépendante. Aussi, selon une autre caractéristique de l'invention, il est prévu un montage comprenant plusieurs supports permettant de traiter simultanément plusieurs pièces.In an industrial context, there is, of course, no question of treating each part chemically or electrolytically in a unitary and independent manner. Also, according to another characteristic of the invention, an assembly is provided comprising several supports making it possible to simultaneously treat several parts.

Ainsi, le dispositif de retenue selon l'invention est constitué par un châssis ayant la forme d'un cadre (20) portant une succession de supports pour former une cassette de manutention (21).Thus, the retaining device according to the invention consists of a frame having the form of a frame (20) carrying a succession of supports to form a handling cassette (21).

Les figures 10, 11 et 12 illustrent une telle disposition constituée donc par un cadre périphérique (20) de forme avantageusement rectangulaire comprenant une succession d'ensembles de retenue porte-support (22) déposés parallèlement les uns aux autres comme, par exemple, treize ensembles (22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h, 22i, 22j, 22k, 221, 22m). Le cadre périphérique (20) est réalisé grâce à un assemblage de quatre profilés en titane ayant la forme d'un "L" pour lui donner sa rigidité et notamment sa tenue mécanique en torsion, à savoir, deux profilés longitudinaux (23, 24) et deux profilés d'extrémité (25, 26). Tous les ensembles de retenue porte-support (22) sont fixés aux profilés d'extrémité (25, 26) pour s'étendre parallèlement entre eux et aux deux profilés longitudinaux (23, 24). Chacun des ensembles de retenue (22) est monobloc, réalisé en titane, et est formé par une base (27) ayant ia forme d'un profilé en forme de "U" ouvert aux extrémités (32a, 32b) dont chacune des parois longitudinales verticales (29, 30) présente une succession de saillies pour former deux à deux les pattes de retenue (8a, 8b) d'une succession de supports de pièces (7).Figures 10, 11 and 12 illustrate such an arrangement therefore constituted by a peripheral frame (20) of advantageously rectangular shape comprising a succession of support holder retaining assemblies (22) deposited parallel to each other such as, for example, thirteen sets (22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h, 22i, 22j, 22k, 221, 22m). The peripheral frame (20) is produced by means of an assembly of four titanium profiles having the shape of an "L" to give it its rigidity and in particular its mechanical resistance in torsion, namely, two longitudinal profiles (23, 24) and two end sections (25, 26). All the support holder retaining assemblies (22) are fixed to the end profiles (25, 26) to extend parallel to each other and to the two longitudinal profiles (23, 24). Each of the retaining assemblies (22) is in one piece, made of titanium, and is formed by a base (27) having the form of a "U" shaped profile open at the ends (32a, 32b) each of whose longitudinal walls vertical (29, 30) has a succession of projections to form two by two the retaining tabs (8a, 8b) of a succession of workpiece supports (7).

Notons que chaque ensemble de retenue (22) est fixé par les extrémités de sa paroi horizontale (290) aux profilés d'extrémité (25, 26) grâce à des éléments de paroi (32) faisant saillie de la paroi horizontale (33) de chaque profilé d'extrémité.Note that each retaining assembly (22) is fixed by the ends of its horizontal wall (290) to the end sections (25, 26) by means of wall elements (32) projecting from the horizontal wall (33) of each end profile.

Chaque cassette peut, par exemple, comprendre treize ensembles de retenue (22) comprenant chacun vingt-cinq supports de pièces (7). Avec une telle cassette il est donc possible de procéder aux déplacements divers du ou des traitement(s) simultané(s) de plusieurs pièces, et dans l'exemple donné, des trois cent vingt-cinq pièces de retenues sur la cassette. En effet, l'élasticité vers l'extérieur des extrémités de chacun des supports permet la retenue de toutes les pièces et le châssis peut alors être déplacé, manipulé, retourné, stocké et immergé aussi bien horizontalement que verticalement dans les bains de traitement, sans qu'aucune pièce ne tombe.Each cassette can, for example, comprise thirteen retaining assemblies (22) each comprising twenty-five coin supports (7). With such a cassette it is therefore possible to carry out various displacements of the simultaneous treatment (s) of several pieces, and in the example given, of the three hundred and twenty-five pieces of retentions on the cassette. Indeed, the outward elasticity of the ends of each of the supports allows the retention of all the parts and the chassis can then be moved, manipulated, turned, stored and immersed both horizontally and vertically in the treatment baths, without that no coin falls.

L'invention concerne aussi les moyens mis en oeuvre pour la mise en place des pièces sur la cassette et les moyens mis en oeuvre pour leur retrait ainsi que l'installation comprenant ces moyens.The invention also relates to the means used for placing the parts on the cassette and the means used to remove them, as well as the installation comprising these means.

Ainsi, l'installation (100) comprend un poste de mise en place des pièces sur la cassette (40), lequel poste comprenant des moyens de déplacement (41) permettant le déplacement pas à pas des cassettes (21) des moyens d'alimentation (42) en pièces, des moyens de mise en place des pièces (43) et des moyens de rapprochement (44) permettant le rapprochement des pattes de retenue, l'ensemble de ces moyens étant porté par un bâti (45).Thus, the installation (100) comprises a station for placing the parts on the cassette (40), which station comprising displacement means (41) allowing the cassettes (21) to move step by step in the supply means (42) in parts, means for positioning the parts (43) and approximation means (44) allowing the approximation of the retaining tabs, all of these means being carried by a frame (45).

Les moyens de déplacement (41) sont constitués, par exemple, par deux bandes latérales continues (46a, 46b) sur lesquelles reposent les cassettes (21), lesdites bandes étant entraînées en déplacement par un moteur électrique (47).The displacement means (41) consist, for example, of two continuous lateral bands (46a, 46b) on which the cassettes (21) rest, said bands being driven in displacement by an electric motor (47).

Les moyens d'alimentation en pièces (42) sont, par exemple, constitués par un bol vibrant (48) alimentant un ensemble de distribution (49) incliné comprenant deux parois parallèles (49a, 49b) entre lesquelles s'accumulent et s'organisent les pièces à traiter selon des rangées et des lignes successives dont la première se trouve en appui contre une butée transversale (49c), et ce, parallèlement aux ensembles de retenue qui se déplacent pas à pas sous les moyens d'alimentation.The parts supply means (42) are, for example, constituted by a vibrating bowl (48) supplying an inclined distribution assembly (49) comprising two parallel walls (49a, 49b) between which accumulate and organize the parts to be treated in successive rows and lines, the first of which is in abutment against a transverse stop (49c), and this, parallel to the retaining assemblies which move step by step under the supply means.

Les moyens de mise en place (43) sont constitués par un automate (50) monté pivotant sur un support (51) pour pouvoir prendre deux positions, une position de préhension des pièces (P1) dans laquelle il est incliné en regard de la ligne des pièces en attente disposée en butée dans les moyens d'alimentation, et une position de mise en place et d'engagement des pièces (P2) sur les supports correspondants, position dans laquelle l'automate est sensiblement vertical au droit de la rangée de supports à équiper de pièces. L'automate comprend à son extrémité un support mobile (53) comprenant une rangée de doigts de préhension (52) en nombre égal au nombre de pièces à mettre en place. Chacun des doigts (52) comprend des moyens de succion permettant la retenue des pièces par aspiration afin de les prendre de la ligne des pièces en attente et pour les déplacer et les engager sur les supports correspondants.The positioning means (43) consist of an automaton (50) pivotally mounted on a support (51) in order to be able to take two positions, a position for gripping the parts (P1) in which it is inclined facing the line waiting pieces arranged in abutment in the supply means, and a position for placing and engaging the pieces (P2) on the corresponding supports, position in which the automaton is substantially vertical in line with the row of supports to be fitted with parts. The automaton comprises at its end a movable support (53) comprising a row of gripping fingers (52) equal in number to the number of parts to be put in place. Each of the fingers (52) comprises suction means allowing the retention of parts by suction in order to take them from the line of waiting parts and to move and engage them on the corresponding supports.

Préalablement à la mise en place des pièces sur les supports, les moyens de rapprochement (44) des pattes des supports sont mis en oeuvre pour rapprocher. Ces moyens sont constitués par deux mâchoires réalisées par des profils cylindriques (55a, 55b) montés à l'extrémité de bicyclettes pivotantes (56a, 56b) sur un châssis (57) mobile verticalement. Le rapprochement des mâchoires étant commandé, par exemple, par un système de rampe (58).Prior to the positioning of the parts on the supports, the approximation means (44) of the legs of the supports are used to bring the components closer together. These means consist of two jaws made by cylindrical profiles (55a, 55b) mounted at the end of swivel bicycles (56a, 56b) on a chassis (57) movable vertically. The approximation of the jaws being controlled, for example, by a ramp system (58).

Le bâti (45) avec ses moyens de déplacement (41) est prolongé en amont pour recevoir les cassettes avec les pièces déjà traitées, lesdites cassettes étant donc en amont posées sur les bandes transporteuses (46a, 46b) pour être déplacées pas à pas et vidées de leurs pièces. A cet effet, les cassettes (21) sont posées à l'envers sur les bandes et entre les taquets de guidage et de positionnement, et des moyens de rapprochement (44) identiques à ceux déjà décrits sont prévus pour rapprocher les pattes de retenue des ensembles de retenue et ainsi libérer les pièces qui tombent par leurs propres poids dans un conteneur de stockage (59).The frame (45) with its displacement means (41) is extended upstream to receive the cassettes with the parts already treated, said cassettes therefore being upstream placed on the conveyor belts (46a, 46b) to be moved step by step and emptied of their parts. To this end, the cassettes (21) are placed upside down on the strips and between the guide and positioning tabs, and approximation means (44) identical to those already described are provided for bringing the retaining tabs of the restraint systems and thus release the parts which fall by their own weights in a storage container (59).

Les cassettes ainsi progressivement vidées sont alors soulevées et retournées par des moyens de retournement (60) pour être ensuite reposées sur les bandes transporteuses et être à nouveau fournies en pièces à traiter.The cassettes thus progressively emptied are then lifted and turned over by turning means (60) to then be rested on the conveyor belts and again be supplied with parts to be treated.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
