Description

La présente invention concerne un perfectionnement dans les traitements de surface de pièces utilisant le principe d'immersion dans une ou plusieurs cuves de traitement et transfert des pièces entre ces cuves, notamment les traitements électrochimiques de surfaces de pièces métalliques, et plus particulièrement un traitement par anodisation de pièces en aluminium.
On peut citer, à titre d'exemples de traitements anodiques de l'aluminium et de ses alliages, l'anodisation barrière ou passivation anodique, l'anodisation poreuse en milieu acide ou la dissolution anodique, voire le polissage électrolytique, l'anodisation dure ou auto-colorée.The present invention relates to an improvement in the surface treatment of parts using the principle of immersion in one or more tanks for the treatment and transfer of parts between these tanks, in particular the electrochemical treatments of surfaces of metal parts, and more particularly a treatment by anodizing aluminum parts.
Examples of anodic treatments of aluminum and its alloys are anodic anodization or anodic passivation, porous anodization in an acid medium or anodic dissolution, or even electrolytic polishing, hard anodizing or self-colored.

La présente invention concerne notamment un perfectionnement d'une installation de traitement et plus particulièrement de sa chaîne de convoyage des pièces.The present invention relates in particular to an improvement of a treatment plant and more particularly of its parts conveyor chain.

On connaît déjà des installations de traitement de surface de pièces en aluminium fonctionnant par batchs . Le document DE 2 119 401 décrit une telle installation, comprenant des chariots motorisés effectuant un parcours au-dessus de plusieurs bacs de traitement. Les chariots sont munis de bras mobiles effectuant des mouvements verticaux pour plonger des lots d'objets à traiter dans les bacs successifs et les en ressortir. Ce document concerne plus spécifiquement un système de freinage de sécurité de ses chariots.Surface treatment installations of aluminum parts operating in batches are already known. The document DE 2 119 401 describes such an installation, comprising motorized trolleys running over several treatment tanks. The trolleys are provided with movable arms making vertical movements to plunge batches of objects to be treated in successive bins and out of them. This document relates more specifically to a safety braking system of its trolleys.

Dans la demande de brevet français N° 0603687 , et dans la demande de brevet WO2006/00199 , dont le contenu est incorporé ici par référence, les déposants ont déjà décrit des installations de traitement de surface de pièces comprenant une pluralité de cuves de traitement agencées en série et équipées chacune d'un tambour rotatif muni de moyens de fixation temporaire de pièces à traiter et dont l'axe est monté horizontalement en rotation de telle sorte que la majeure partie de chaque tambour soit immergée dans un liquide de traitement contenu dans la cuve correspondante, et un système dé convoyage destiné à alimenter chaque tambour en pièces à traiter et à retirer du dit tambour les pièces déjà traitées.In the French patent application No. 0603687 , and in the patent application WO2006 / 00199 , the contents of which are incorporated herein by reference, the applicants have already described surface treatment facilities of parts comprising a plurality of processing tanks arranged in series and each equipped with a rotary drum provided with means for temporarily fixing parts to process and whose axis is mounted horizontally in rotation so that the major part of each drum is immersed in a treatment liquid contained in the corresponding vessel, and a conveying system intended to supply each drum with parts to be treated and to remove from said drum the parts already treated.

Ces pièces sont mises en place sur des cassettes, comme par exemple celles divulguées dans la demande de brevet EP-A-1 433 537 , lesdites cassettes étant mises en place sur la périphérie d'un tambour pivotant. Le système de convoyage comprend deux chaînes parallèles, agencées de part et d'autre des cuves, dont les axes de convoyage sont perpendiculaires aux axes des tambours rotatifs. Chaque cassette passe alternativement d'une chaîne à l'autre après avoir passé dans une cuve de traitement. Ce système de convoyage nécessite donc un dispositif d'entraînement pour chaque chaîne et plusieurs dispositifs de transfert entre les chaînes et les cuves.
La présente invention apporte un perfectionnement au système de transfert des pièces à traiter.These parts are placed on cassettes, such as those disclosed in the patent application EP-A-1,433,537 , said cassettes being placed on the periphery of a pivoting drum. The conveying system comprises two parallel chains, arranged on either side of the tanks, whose conveying axes are perpendicular to the axes of the rotary drums. Each cassette passes alternately from one chain to another after passing through a treatment tank. This conveying system therefore requires a drive device for each chain and several transfer devices between the chains and the tanks.
The present invention provides an improvement to the transfer system of the parts to be treated.

À cet effet, l'invention propose une installation de traitement de surface de pièces comprenant une pluralité de cuves de traitement agencées en série, équipées de tambours rotatifs munis de moyens de fixation temporaire de pièces à traiter, et dont les axes sont montés horizontalement en rotation de telle sorte que la majeure partie de chaque tambour soit immergée dans un liquide de traitement contenu dans la cuve correspondante, et une chaîne de convoyage destinée à alimenter chaque tambour en pièces à traiter et à retirer du dit tambour des pièces déjà traitées, installation dans laquelle le dit convoyage s'effectue sur un axe général, les axes des tambours étant parallèles entre eux et parallèles à l'axe général de la chaîne de convoyage.For this purpose, the invention proposes a room surface treatment installation comprising a plurality of treatment tanks arranged in series, equipped with rotary drums provided with means for temporarily fixing workpieces, and whose axes are mounted horizontally in rotation so that the major part of each drum is immersed in a treatment liquid contained in the corresponding tank, and a conveyor chain for supplying each drum with parts to be treated and to remove from said drum parts already treated, installation wherein said conveying is on a general axis, the axes of the drums being parallel to each other and parallel to the general axis of the conveyor chain.

De préférence, les axes des tambours sont agencés sensiblement dans le même plan vertical et l'axe général de la chaîne de convoyage est disposé dans le plan vertical contenant les axes de rotation des tambours.Preferably, the axes of the drums are arranged substantially in the same vertical plane and the general axis of the conveyor chain is arranged in the vertical plane containing the axes of rotation of the drums.

Selon un mode d'exécution particulier de l'installation de traitement de surface de pièces selon l'invention, la périphérie d' un tambour comprend une succession de glissières ou de rails d'axe parallèle à l'axe de rotation du tambour, destinés à recevoir des cassettes supportant un ensemble de pièces à traiter, les cassettes étant destinées à faire avec le tambour sur lequel elles sont fixées un tour complet dans le liquide de traitement, tandis que la chaîne de convoyage est destinée à alimenter en cassettes de pièces à traiter le tambour et à retirer du tambour les cassettes de pièces déjà traitées, la chaîne de convoyage est disposée au-dessus des cuves, et l'axe général de convoyage est parallèle à l'axe de rotation des tambours et disposé dans l'espace vertical comprenant les cuves.According to a particular embodiment of the surface treatment plant of parts according to the invention, the periphery of a drum comprises a succession of rails or rails with an axis parallel to the axis of rotation of the drum, intended to receive cassettes supporting a set of parts to be treated, the cassettes being intended to do with the drum on which they are fixed a complete turn in the treatment liquid, while the conveyor chain is intended to supply cassettes of parts to treat the drum and to remove from the drum the cassettes of parts already treated, the conveyor chain is disposed above the tanks, and the general axis of conveying is parallel to the axis of rotation of the drums and disposed in the vertical space comprising the tanks.

Dans cette installation, les tambours peuvent être agencés de sorte que leurs paires de glissières qui viennent momentanément en position supérieure émergent des liquides des traitements et sont alignées les unes avec les autres, de sorte que tous les transferts peuvent s'effectuer simultanément.In this installation, the drums can be arranged so that their pairs of slides that momentarily come to the upper position emerge from the process liquids and are aligned with each other, so that all transfers can be performed simultaneously.

Cette installation peut comporter des glissières de transfert disposées entre deux cuves successives et alignées avec les glissières des tambours en position supérieure.
C'est installation peut comporter des moyens d'aspersion des pièces au niveau des glissières de transfert.This installation may include transfer slides arranged between two successive tanks and aligned with the slides of the drums in the upper position.
This installation may include means for spraying parts at the transfer slides.

Selon un mode d'exécution préféré de l'invention, les opérations de transfert de pièces de la chaîne de convoyage sont cadencées et synchrones.According to a preferred embodiment of the invention, the parts transfer operations of the conveyor chain are timed and synchronous.

Selon un mode d'exécution de l'invention, la chaîne de convoyage comprend au moins un chariot mobile effectuant un déplacement de va et vient sur un rail de guidage afin de réaliser par ce déplacement le dégagement, par translation horizontale, d'une ou de plusieurs cassettes comprenant les pièces déjà traitées, et la mise en place, également par translation horizontale, d'une ou de plusieurs cassettes comprenant les pièces non encore traitées.According to one embodiment of the invention, the conveyor chain comprises at least one movable carriage moving back and forth on a guide rail in order to achieve by this displacement the clearance, by horizontal translation, of one or several cassettes comprising the parts already processed, and the establishment, also by horizontal translation, of one or more cassettes comprising the parts not yet processed.

Le chariot mobile peut comprendre un moteur relié à un pignon coopérant avec une crémaillère afin d'assurer ses déplacements de va et vient sur le rail.The mobile carriage may comprise a motor connected to a pinion cooperating with a rack to ensure its movements back and forth on the rail.

La partie inférieure du chariot peut comprendre une barre horizontale de commande qui porte au moins un bras vertical terminé par une pièce d'actionnement, tandis que la barre de commande est retenue à la partie inférieure du chariot par l'intermédiaire de deux biellettes pivotantes, le pivotement des biellettes assurant le déplacement vers le bas et vers le haut de ladite barre.The lower part of the carriage may comprise a horizontal control bar which carries at least one vertical arm terminated by an actuating part, while the control bar is retained at the bottom of the carriage by means of two pivoting rods, the pivoting rods ensuring the movement downwards and upwards of said bar.

Les figures 1 et 2 illustrent une installation de traitement de surface de pièces métalliques tel que, par exemple, une anodisation de pièces en aluminium, qui nécessite une succession de cuves (4) contenant des liquides différents, tels que liquide de dégraissage, liquide de satinage, solution électrolytique, liquide de rinçage, etc. L'une des cuves de traitement est remplie d'une solution électrolytique, par exemple de l'acide sulfurique, et permet de réaliser l'anodisation de pièces en aluminium fixées sur des cassettes. Pour ce type de traitement la cuve comprend deux électrodes tandis que le tambour est alimenté en courant électrique de polarité opposée à celle des électrodes, ledit courant électrique étant transmis aux pièces à traiter par l'intermédiaire successivement du tambour et des cassettes, tel que cela est décrit dans la demande de brevet français N° 0603687 des demandeurs, dont le contenu est incorporé ici par référence. Selon le procédé mettant en oeuvre l'installation de traitement de l'invention, on immerge chaque pièce dans chaque cuve, en lui faisant faire au moins un mouvement de rotation tel que les bulles d'air et poches d'air susceptibles d'être créées à l'intérieur de la cuve au contact de la pièce sont chassées, permettant ainsi au liquide de traitement de traiter l'intégralité de la surface de la pièce, rendant le traitement parfaitement homogène.The Figures 1 and 2 illustrate an installation for surface treatment of metal parts such as, for example, anodizing of aluminum parts, which requires a succession of tanks (4) containing different liquids, such as degreasing liquid, satinizing liquid, electrolytic solution, rinse aid, etc. One of the treatment tanks is filled with an electrolytic solution, for example sulfuric acid, and makes it possible to anodize aluminum parts fixed on cassettes. For this type of treatment the tank comprises two electrodes while the drum is supplied with electric current of polarity opposite to that of the electrodes, said electric current being transmitted to the parts to be processed via the drum and cassettes successively, as this is described in the French patent application No. 0603687 applicants whose contents are incorporated herein by reference. According to the method implementing the treatment plant of the invention, each piece is immersed in each tank, making it do at least one rotational movement such as air bubbles and air pockets likely to be created inside the tank in contact with the part are driven, allowing the treatment liquid to treat the entire surface of the part, making the treatment perfectly homogeneous.

Un nombre déterminé desdites pièces à traiter sont placées au préalable sur un support ou cassette (5) comprenant au moins un organe de maintien apte à retenir chacune d'entre elles. Les cassettes sont par exemple celles décrites dans la demande de brevet européen EP-A-1 433 537 , qui comprennent un ensemble d'organes de maintien de pièces permettant de fixer sur une seule cassette plusieurs pièces. La chaîne de convoyage (14) comprend plusieurs chariots (9) afin d' engager les cassettes de pièces à traiter sur les tambours et de dégager de chacun des tambours les cassettes de pièces traitées.A predetermined number of said pieces to be treated are placed beforehand on a support or cassette (5) comprising at least one holding member adapted to retain each of they. The cassettes are for example those described in the European patent application EP-A-1,433,537 , which comprise a set of parts holding members for fixing on a single cassette several parts. The conveyor chain (14) comprises a plurality of carriages (9) to engage the cassettes of workpieces on the drums and to disengage the cassettes of processed parts from each of the drums.

Comme l'illustre la figure 3, on fait ainsi faire une ou plusieurs rotations complètes de 360°, en fixant les pièces (1) à traiter sur la périphérie d'un tambour (2) monté en rotation dans chaque cuve de traitement (4) autour d'un axe horizontal (X, X'), ledit tambour étant immergé dans le liquide de traitement (3) contenu dans la cuve (4), à l'exception de sa portion supérieure, qui se trouve hors du liquide afin de permettre la mise en place et le retrait des pièces. Selon le mode de réalisation illustré, le tambour (2) comprend, à sa périphérie externe une succession de 6 paires de glissières (6), destinées à recevoir les cassettes (5) servant de support des pièces à traiter. Ainsi les cassettes comprenant les pièces non encore traitées sont engagées par déplacement horizontal dans la glissière libre et non immergée, disposée au sommet du tambour. L'axe de coulissement de chacune des glissières (6) est parallèle à l'axe de rotation du tambour correspondant.As illustrated by figure 3 , one or more complete rotations of 360 ° are made, by fixing the parts (1) to be treated on the periphery of a drum (2) rotatably mounted in each treatment tank (4) around a horizontal axis (X, X '), said drum being immersed in the treatment liquid (3) contained in the tank (4), with the exception of its upper portion, which is outside the liquid to allow the introduction and the removal of parts. According to the illustrated embodiment, the drum (2) comprises, at its outer periphery, a succession of 6 pairs of slides (6) intended to receive the cassettes (5) serving to support the parts to be treated. Thus the cassettes comprising the parts not yet treated are engaged by horizontal displacement in the free slide and not immersed, disposed at the top of the drum. The axis of sliding of each of the slides (6) is parallel to the axis of rotation of the corresponding drum.

La cuve (4) comprend un moteur (7) destiné à mettre en rotation le tambour pivotant (2) grâce à la coopération d'une roue dentée (70) avec une succession de piges (71) montées parallèles entre elles, et entre les deux flasques de l'un des flancs du tambour, comme par exemple la couronne d'entraînement, telle que décrite dans la demande de brevet français N° 0603687 .
L'ensemble de la chaîne de convoyage illustré dans les figures 1 et 2 fonctionne par séquences de déplacements cadencés et synchrones. A chacune des séquences dans les 5 cuves courtes, une cassette traitée est dégagée et une nouvelle cassette non encore traitée est engagée sur un tambour, puis est immergée lors de la rotation du tambour correspondant, pour faire un tour complet, dans le liquide de traitement. Dans la 4ème cuve, qui contient un tambour d'une longueur équivalente à 4 cassettes, celles-ci font 4 tours complets et 4 translations avant d'être dégagées. La chaîne de convoyage comporte une station d'alimentation (15), une station de dégagement (16), et une zone de transfert entre la 2ème et la 3ème cuve plus longue que les autres, qui peut servir de station d'aspersion par un liquide de rinçage.The tank (4) comprises a motor (7) for rotating the pivoting drum (2) by the cooperation of a toothed wheel (70) with a succession of rods (71) mounted parallel to each other, and between two flanges of one of the sides of the drum, such as the driving ring, as described in the French patent application No. 0603687 .
The entire conveyor chain illustrated in the Figures 1 and 2 operates in sequences of synchronous and synchronous movements. At each of the sequences in the short tanks, a treated cassette is disengaged and a new untreated cassette is engaged on a drum, and then immersed during the rotation of the corresponding drum, to make a complete turn, in the treatment liquid. . In the 4 th vessel, which contains a drum of a length equivalent to four cassettes, these are four complete revolutions and four translations before being released. The conveyor chain comprises a feed station (15), a release station (16), and a transfer zone between the 2nd and 3rd tank longer than the other, which can be used spray station with a rinsing liquid.

Pour chaque cuve, la chaîne de convoyage (14) comprend au moins un chariot mobile (8) associé, effectuant un déplacement limité de va et vient sur un rail de guidage (9) afin de permettre, par ce déplacement de va et vient, le dégagement d'une ou de plusieurs cassettes comprenant les pièces déjà traitées, et la mise en place d'une ou de plusieurs cassettes comprenant les pièces non encore traitées.For each tank, the conveyor chain (14) comprises at least one associated carriage (8), making a limited movement back and forth on a guide rail (9) to allow, by this movement back and forth, the release of one or more cassettes comprising the parts already treated, and the establishment of one or more cassettes comprising the parts not yet treated.

Chacun des chariots (8) comprend un moteur relié à un pignon coopérant avec une crémaillère afin d'assurer ses déplacements de va et vient sur le rail.
A sa partie inférieure le chariot (8) comprend une barre horizontale de commande (10) qui comprend au moins un bras vertical (11a, 11b) de retenue d'une pièce d'actionnement (12). Cette pièce d'actionnement est destinée à dégager par coulissement la cassette de pièces déjà traitées c'est-à-dire celles ayant fait un tour complet dans le liquide et engager la cassette suivante des pièces non encore traitées. La barre de commande est retenue à la partie inférieure du chariot par l'intermédiaire de deux biellettes pivotantes (17a, 17b), le pivotement des biellettes assurant le déplacement vertical de la barre. Grâce aux biellettes pivotantes (17a, 17b) la barre de commande se déplace vers le bas et vers le haut parallèlement à elle même.
Les figures 4 et 5 illustrent le fonctionnement d'un chariot mobile (8). Ainsi, comme cela est illustré à la figure 4, le chariot (8) en position de dégagement est tel que la barre horizontale (10) est en position haute de dégagement, ce qui permet au chariot de se déplacer vers l'amont de la chaîne, selon la flèche D, pour une nouvelle action. Une fois en position d'action, la barre horizontale est déplacée vers le bas, tel que cela est illustré à
la figure 5, pour que la ou les pièces d'actionnement 12 puissent venir dans le plan des cassettes (5), puis le chariot (8) se déplace vers l'aval de la chaîne, selon la flèche (A), dans le sens inverse de celui du dégagement (D), afin d'engager dans la glissière (6) une nouvelle cassette, et faire progresser d'une position une cassette et/ou dégager la cassette de pièces déjà traitées. On observera que sur la figure 5, le bras vertical (11a) pousse la cassette de gauche, alors que le bras vertical (11b) simultanément tire la deuxième cassette et pousse la troisième cassette.Each of the carriages (8) comprises a motor connected to a pinion cooperating with a rack to ensure its movements back and forth on the rail.
At its lower part the carriage (8) comprises a horizontal control bar (10) which comprises at least one vertical arm (11a, 11b) for retaining an actuating piece (12). This actuating piece is intended to slide the cassette out of pieces already treated, that is to say those having made a complete revolution in the liquid and engage the next cassette parts not yet treated. The control bar is retained at the bottom of the carriage by means of two pivoting rods (17a, 17b), the pivoting rods ensuring the vertical movement of the bar. Thanks to the pivoting rods (17a, 17b) the control rod moves downwards and upwards parallel to itself.
The Figures 4 and 5 illustrate the operation of a mobile carriage (8). Thus, as illustrated in figure 4 , the carriage (8) in the release position is such that the horizontal bar (10) is in the upper disengagement position, which allows the carriage to move upstream of the chain, according to the arrow D, for a new action. Once in the action position, the horizontal bar is moved downward, as shown in FIG.
the figure 5 , so that the actuating part (s) 12 can come into the plane of the cassettes (5), then the carriage (8) moves downstream of the chain, according to the arrow (A), in the opposite direction of that of the clearance (D), to engage in the slide (6) a new cassette, and advance a position of a cassette and / or clear the cassette parts already processed. We will observe that on the figure 5 the vertical arm (11a) pushes the left cassette, while the vertical arm (11b) simultaneously pulls the second cassette and pushes the third cassette.

L'homme du métier aura notamment déduit de la description ci-dessus que contrairement à la demande de brevet WO2006/00199 , où il est prévu une double chaîne de convoyage qui est disposée latéralement et dont l'axe général s'étend perpendiculairement à l'axe de rotation des tambours, dans l'installation de l'invention la chaîne de convoyage (14) est disposée au-dessus des cuves, et l'axe général de convoyage est parallèle à l'axe de rotation des tambours et est disposé dans l'espace vertical (E) comprenant les cuves, et l'axe général de convoyage (Z, Z') est parallèle à l'axe de rotation des tambours, et avantageusement disposé dans le plan vertical (P) contenant l'axe de rotation (X, X') des tambours.The person skilled in the art will in particular have deduced from the description above that contrary to the patent application WO2006 / 00199 , where there is provided a double conveyor chain which is arranged laterally and whose general axis extends perpendicularly to the axis of rotation of the drums, in the installation of the invention the conveyor chain (14) is arranged above the tanks, and the general axis of conveying is parallel to the axis of rotation of the drums and is arranged in the vertical space (E) comprising the tanks, and the general axis of conveying (Z, Z ' ) is parallel to the axis of rotation of the drums, and advantageously arranged in the vertical plane (P) containing the axis of rotation (X, X ') of the drums.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté à titre d'exemple, mais elle comprend de nombreuses variantes techniques ainsi que leurs combinaisons :
Ainsi, la figure 3 illustre un tambour avec six positions de fixation de cassettes. Ce nombre pourrait être différent. Avec par exemple seulement 2 positions de fixations, on peut réaliser une cuve de petite dimension nécessitant peu de liquide de traitement, en particulier pour une étape de traitement rapide. Dans ce cas, la structure du tambour n'est pas nécessairement cylindrique ou hexagonale mais peut se réduire à deux bras Ainsi, les durées respectives des étapes successives de traitement peuvent être modulées entre elles grâce à des nombres de positions de fixation différentes sur les tambours.Of course, the invention is not limited to the embodiment described and shown by way of example, but it comprises numerous technical variants as well as their combinations:
So, the figure 3 illustrates a drum with six cassette attachment positions. This number could be different. With, for example, only two fixing positions, it is possible to make a small tank requiring little treatment liquid, in particular for a fast treatment stage. In this case, the structure of the drum is not necessarily cylindrical or hexagonal but can be reduced to two arms. Thus, the respective durations of the successive processing steps can be modulated with each other thanks to the number of different fixing positions on the drums. .

La chaîne de convoyage pourrait n'utiliser qu'un seul moteur, les mouvements de tous les chariots mobiles s'effectuant via un système d'entraînements mécaniques.
Les cassettes citées ci-dessus conviennent particulièrement au traitement d'un grand nombre de pièces de petite dimension. Dans le cas du traitement de grandes pièces, celles-ci peuvent être fixées directement sur un tambour, ou par d'autres moyens de fixation que des glissières.The conveyor chain could use only one motor, the movements of all the mobile carriages taking place via a system of mechanical drives.
The cassettes mentioned above are particularly suitable for processing a large number of small parts. In the case of the treatment of large parts, they can be fixed directly on a drum, or by other means of attachment as slides.
