Description

" PROCEDE DE PEINTURE D'OBJETS ET SUPPORT CORRESPONDANT " "METHOD OF PAINTING OBJECTS AND CORRESPONDING MEDIUM"
La présente invention est relative à un procédé pour peindre des objets portés par des supports, du type dans lequel, après un ou plusieurs cycles de peinture, chaque support est refroidi par un fluide cryogénique puis soumis à une action mécanique d'élimination de la peinture qui s'y est accumulée.The present invention relates to a method for painting objects carried by supports, of the type in which, after one or more painting cycles, each support is cooled by a cryogenic fluid and then subjected to a mechanical action of removing the paint that has accumulated there.
Dans les installations industrielles produisant des objets peints, comme on en rencontre notamment dans les industries de l'automobile, des jouets et de l' électro-ménager, les objets à peindre sont portés par des supports, qui sont par exemple des crochets, des balancelles, des chariots, etc., et subissent successivement un cycle de peinture comportant notamment une étape de dépôt de la peinture et une étape de séchage/cuisson de la peinture déposée. Les supports sont ensuite recyclés pour recevoir de nouveaux objets à peindre.In industrial installations producing painted objects, such as are encountered in particular in the automobile, toy and household appliance industries, the objects to be painted are carried by supports, which are for example hooks, swings, carts, etc., and successively undergo a painting cycle comprising in particular a step of depositing the paint and a step of drying / baking the deposited paint. The supports are then recycled to receive new objects to paint.
Inévitablement, les supports des objets subissent aussi, au moins en partie, le cycle de peinture. Par suite, à chaque cycle, une couche de peinture supplémentaire s'y accumule. Il est donc nécessaire de les nettoyer périodiquement.Inevitably, the supports of the objects also undergo, at least in part, the painting cycle. As a result, with each cycle, an additional layer of paint builds up there. It is therefore necessary to clean them periodically.
Pour effectuer ce nettoyage, appelé aussi décapage, il a été proposé de fragiliser la peinture par un fluide cryogénique tel que l'azote liquide, puis d'éliminer par une action mécanique la peinture fragilisée. Cependant, comme les peintures sont précisément conçues pour assurer un bon accrochage sur les objets à peindre, elles s'accrochent aussi fermement sur les supports, qui sont métalliques comme les objets traités. De plus, certaines peintures sont peu fragiles à froid. Il s'ensuit que le décrochage de la peinture est difficile, surtout si la couche de peinture à éliminer est mince.To carry out this cleaning, also called pickling, it has been proposed to weaken the paint with a cryogenic fluid such as liquid nitrogen, then remove the weakened paint by mechanical action. However, as the paints are precisely designed to ensure good adhesion to the objects to be painted, they also hang firmly on the supports, which are metallic like the treated objects. In addition, some paintings are not very fragile when cold. It follows that it is difficult to remove the paint, especially if the layer of paint to be removed is thin.
Ceci explique que dans les techniques de décapage cryogénique actuelles, il soit nécessaire de faire appel à une opération de grenaillage prolongée pour décrocher parfaitement la peinture des supports, après le refroidissement cryogénique. Or, le grenaillage présente de nombreux inconvénients : investissements élevés ; risque d'introduction de poussières ; risque de fragiliser mécaniquement les supports et usure rapide de ces derniers ; efficacité parfois limitée, notamment dans le cas de couches de faible épaisseur de peintures mal fragilisées et que le grenaillage, par l'énergie apportée par l'impact, réchauffe sans les décoller entièrement du support. Un aut;re inconvénient de la technique de cryodécapage est le suivant : à la sortie du dispositif de décapage, les supports sont encore à basse température et, par suite, se couvrent de givre ; puis, lorsqu'ils sont réchauffés, ils s'oxydent, et la rouille, outre son effet destructeur, produit des poussières qui polluent le bain de peinture.This explains why in the current cryogenic stripping techniques, it is necessary to use an extended peening operation to perfectly unhook the paint from the supports, after cryogenic cooling. However, shot blasting has many disadvantages: high investments; risk of introducing dust; risk of mechanically weakening the supports and rapid wear of the latter; sometimes limited effectiveness, especially in the case of thin layers of poorly weakened paints and that shot peening, by the energy provided by impact, heats up without detaching them entirely from the support. Another drawback of the cryopainting technique is as follows: at the outlet of the pickling device, the supports are still at low temperature and, consequently, become covered with frost; then, when heated, they oxidize, and rust, in addition to its destructive effect, produces dust which pollutes the paint bath.
L'invention a pour but de fournir un procédé éliminant à la fois la nécessité d'un grenaillage prolongé et le risque d'oxydation des supports, tout en étant compatible avec les contraintes qu'imposent les procédés de peinture électrostatiques.The object of the invention is to provide a method eliminating both the need for prolonged peening and the risk of oxidation of the supports, while being compatible with the constraints imposed by electrostatic painting processes.
A cet effet, l'invention a pour objet un procédé du type précité, caractérisé en ce que les objets sont portés par des supports revêtus d'une couche mince d'un produit électroconducteur et anti-corrosion sur lequel la peinture adhère moins que sur la matière du support, ce produit étant résistant aux températures cryogéniques et à toute la gamme de température du cycle de peinture.To this end, the subject of the invention is a method of the aforementioned type, characterized in that the objects are carried by supports coated with a thin layer of an electroconductive and anti-corrosion product to which the paint adheres less than on the material of the support, this product being resistant to cryogenic temperatures and to the entire temperature range of the paint cycle.
La couche mince peut notamment comprendre un revêtement métallique, en particulier de zinc.The thin layer may in particular comprise a metallic coating, in particular of zinc.
Dans un mode de mise en oeuvre de l'invention, dans le cas où les objets sont soumis, avant d'être peints, à un traitement assurant un meilleur accrochage de la peinture, on dépose en outre sur ladite couche mince une précouche de peinture avant que les objets soient portés par leurs supports.In one embodiment of the invention, in the case where the objects are subjected, before being painted, to a treatment ensuring better adhesion of the paint, a precoat of paint is also deposited on said thin layer. before the objects are carried by their supports.
L'invention a également pour objet un support pour objets à peindre destiné à la mise en oeuvre du procédé défini ci-dessus. Ce support est caractérisé en ce qu'il est revêtu d'une couche mince d'un produit électroconducteur et anti-corrosion sur lequel la peinture adhère moins que sur la matière du support, ce produit étant résistant aux températures cryogéniques et à toute la gamme de température du cycle de peinture.The invention also relates to a support for objects to be painted intended for the implementation of the method defined above. This support is characterized in that it is coated with a thin layer of an electroconductive and anti-corrosion product on which the paint adheres less than on the material of the support, this product being resistant to cryogenic temperatures and to the whole range. of the paint cycle temperature.
On va maintenant décrire quelques exemples de mise en oeuvre de l'invention.We will now describe some examples of implementation of the invention.
EXEMPLE 1 :EXAMPLE 1:
Des carrosseries d'automobile sont destinées à être peintes. On les suspend à des balancelles galvanisées, portant un revêtement de zinc d'épaisseur 50 à 60 microns environ, soit environ 600 grammes de zinc par mètre carré de surface. Ce revêtement de zinc est obtenu par trempage des balancelles en acier dans un bain de zinc fondu ; en variante, on pourrait également revêtir les balancelles de zinc par voie électrolytique. Les balancelles galvanisées ainsi chargées sont transférées au poste de peinture. Lorsque le cycle de peinture est terminé, la carrosserie est décrochée de la balancelle, et cette dernière est recyclée pour recevoir une autre carrosserie à peindre.Automobile bodies are intended to be painted. They are suspended on galvanized swings, carrying a zinc coating of thickness approximately 50 to 60 microns, that is to say approximately 600 grams of zinc per square meter of surface. This zinc coating is obtained by dipping the steel swings in a bath of molten zinc; alternatively, we could also electroplate zinc swings. The galvanized swings thus loaded are transferred to the painting station. When the painting cycle is finished, the body is detached from the swing, and the latter is recycled to receive another body to paint.
Après un certain nombre de cycles de peinture, chaque balancelle porte une couche épaisse de peinture, et il faut la nettoyer. Pour cela, elle est refroidie par un fluide cryogénique, notamment de l'azote liquide, jusqu'à une température cryogénique à laquelle la peinture est fragilisée, puis on la soumet à des chocs, par exemple au moyen de grenaille, de brosses ou de chaînes.After a certain number of painting cycles, each swing has a thick layer of paint, and it must be cleaned. For this, it is cooled by a cryogenic fluid, in particular liquid nitrogen, to a cryogenic temperature at which the paint is weakened, then it is subjected to shocks, for example by means of shot, brushes or chains.
Grâce à la faible adhérence de la pemiëre couche de peinture sur le revêtement de zinc de la balancelle, lequel n'est pas fragilisé, des chocs peu Intenses produisent rapidement l'élimination de la peinture fragilisée. Ainsi, le décapage est rapide et use très peu la balancelle. De plus, le givre se dépose sur le revêtement de zinc et non pas sur l'acier constitutif de la balancelle, de sorte que celle-ci ne s'oxyde pas lors de son réchauffage.Thanks to the weak adhesion of the first layer of paint on the zinc coating of the swing, which is not weakened, mild impacts quickly produce the elimination of the weakened paint. Thus, the stripping is fast and uses very little the swing. In addition, the frost is deposited on the zinc coating and not on the steel constituting the swing, so that the latter does not oxidize when it is reheated.
EXEMPLE 2 :EXAMPLE 2:
Des carrosseries d'automobile doivent subir un traitement de phosphatation avant d'être peintes, ce afin d'améliorer l'accrochage de la peinture. Dans ce cas, on utilise des balancelles galvanisées sur lesquelles on dépose une prëcouche de peinture avant d'y accrocher les carrosseries. L'ensemble passe ensuite au poste de phosphatation, puis dans le cycle de peinture. Lorsque la carrosserie peinte est décrochée, la balancelle peut être recyclée pour recevoir directement une nouvelle carrosserie et passer au poste de phosphatation. En effet, la précouche de peinture a empêché la phosphatation de la balancelle galvanisée, ce qui garantit une faible adhérence de la couche épaisse de peinture sur cette dernière, et, par suite, un cryodécapage facile, comme dans l'exemple 1 et avec les mêmes avantages. Une nouvelle précouche de peinture est toutefois nécessaire après chaque cryodécapage.Automobile bodies must undergo a phosphating treatment before being painted, in order to improve the adhesion of the paint. In this case, galvanized swings are used on which a pre-coat of paint is deposited before hanging the bodies. The whole then goes to the phosphating station, then into the painting cycle. When the painted body is removed, the swing can be recycled to directly receive a new body and go to the phosphating station. Indeed, the paint prelayer prevented the phosphating of the galvanized swing, which guarantees a weak adhesion of the thick layer of paint on the latter, and, consequently, an easy cryopainting, as in Example 1 and with the same benefits. A new pre-coat of paint is however required after each freeze-drying.
EXEMPLE 3 :EXAMPLE 3:
Des carrosseries d'automobile doivent subir successivement un traitement de galvanisation (anti-corrosion), un traitement de phosphatation (pour améliorer l'accrochage de la peinture) puis un cycle de peinture. Dans ce cas, comme dans l'exemple 2, on dépose sur les balancelles galvanisées une précouche de peinture, puis on y accroche les carrosseries et l'on procède à la galvanisation, à la phosphatation puis à la peinture des carrosseries. La précouche de peinture sert, comme dans l'exemple 2, à conserver l'effet anti-adhérent de la galvanisation des balancelles, et, là encore, une telle précouche doit être déposée sur les balancelles après chaque opération de cryodécapage.Automobile bodies must undergo successively a galvanizing treatment (anti-corrosion), a phosphating treatment (to improve the adhesion of the paint) and then a paint cycle. In this case, as in Example 2, we deposit on the galvanized swings a pre-coat of paint, then the bodies are hung there and galvanizing, phosphating and then painting the bodies. The paint pre-coat is used, as in Example 2, to maintain the non-stick effect of the galvanization of the swings, and, here again, such a pre-coat must be deposited on the swings after each cryopainting operation.
Il est à noter que, dans les exemples ci-dessus, la galvanisation des balancelles conserve leur conductibilité électrique, ce qui permet d'effectuer les opérations de peinture par voie électrostatique.It should be noted that, in the examples above, the galvanization of the swings retains their electrical conductivity, which makes it possible to carry out the painting operations by electrostatic means.
En variante, d'autres revêtements métalliques sur lesquels la peinture adhère peu peuvent remplacer le revêtement en zinc, notamment des revêtements en chrome, nickel ou cuivre, bien qu'ils soient plus coûteux. De plus, on peut avoir recours à d'autres revêtements ayant des propriétés analogues de conductibilité électrique et de tenue aux températures cryogéniques et aux hautes températures de séchage/cuisson des peintures, qui peuvent être de l'ordre de 120 à 190°C.Alternatively, other metallic coatings on which the paint does not adhere can replace the zinc coating, in particular chromium, nickel or copper coatings, although they are more expensive. In addition, it is possible to use other coatings having similar properties of electrical conductivity and resistance to cryogenic temperatures and to high drying / curing temperatures of the paints, which can be of the order of 120 to 190 ° C.
Dans certains cas, pour éviter tout risque de voir la peinture couler sur des pièces suspendues, par manque d'adhérence de la peinture sur leurs supports, on peut, lors du premier cycle de peinture suivant un décapage des supports, déposer une precouche de peinture sur le revêtement de ces supports, puis sécher ou cuire cette précouche, avant d'y accrocher les pièces à peindre. In certain cases, to avoid any risk of seeing the paint run on suspended parts, due to the lack of adhesion of the paint on their supports, it is possible, during the first paint cycle following a stripping of the supports, to deposit a prelayer of paint on the coating of these supports, then dry or bake this precoat, before hanging the parts to be painted.
