Abstract
Description
La présente invention concerne l'application de produits par pulvérisation, par l'intermédiaire d'équipements rotatifs porteurs de pistolets de projection, proposant un système d'alimentation des produits à l'équipement rotatif d'application, offrant des caractéristiques avantageuses pour cette fonction.The present invention relates to the application of products by spraying, by means of rotating equipment carrying spray guns, proposing a system for feeding the products to the rotary application equipment, offering advantageous characteristics for this function. .
Pour l'application de produits de recouvrement, comme les colles, peintures, vernis, etc., par pulvérisation sur les surfaces réceptrices correspondantes, des systèmes sont connus dans lesquels le procédé d'application est réalisé par l'intermédiaire d'équipements rotatifs qui utilisent un système d'alimentation basé sur un distributeur rotatif.For the application of covering products, such as glues, paints, varnishes, etc., by spraying on the corresponding receiving surfaces, systems are known in which the method of application is achieved by means of rotating equipment which use a feeding system based on a rotary distributor.
Le système d'alimentation par l'intermédiaire d'un distributeur rotatif comprend l'acheminement des produits devant être appliqués, au travers de tuyauteries, jusqu'au distributeur rotatif disposé dans l'axe de rotation de l'équipement, où les produits acquièrent la pression appropriée pour être amenés aux pistolets de projection par l'intermédiaire desquels l'application est réalisée.The feed system via a rotary distributor comprises conveying the products to be applied, through pipes, to the rotary distributor disposed in the axis of rotation of the equipment, where the products acquire the appropriate pressure to be fed to the spray guns through which the application is made.
Dans ledit système d'alimentation, les produits devant être appliqués arrivent au distributeur, depuis lequel ils sont distribués aux pistolets de projection intégrés dans un ensemble porteur rotatif, de telle sorte que le distributeur tourne en même temps que l'ensemble porteur des pistolets, de telle sorte que dans ces conditions de rotation, dû aux hautes pressions qu'il doit supporter et au caractère corrosif que les produits devant être appliqués ont habituellement, le distributeur souffre d'un dommage considérable, devant être fréquemment remplacé, avec la complication que cela génère, étant donné la multitude de connexions et d'accouplements des conduits d'entrée et de sortie de celui-ci, et parce que les hautes pressions que doivent supporter lesdits accouplements et connexions, rendent nécessaires des ajustements de précision pour que le montage reste dans les conditions appropriées de fonctionnement.In said supply system, the products to be applied arrive at the dispenser, from which they are distributed to the integrated spray guns in a rotatable carrier assembly, so that the dispenser rotates at the same time as the carrier assembly of the guns, so that under these conditions of rotation, due to the high pressures that it must withstand and the corrosive nature that the products to be applied have usually, the distributor suffers from considerable damage, to be frequently replaced, with the complication that this generates, because of the multitude of connections and couplings of the inlet and outlet ducts thereof, and because the high pressures that these couplings and connections have to support, make it necessary to make precise adjustments so that the assembly remains in the proper operating conditions.
Une solution à ce problème de dommage du distributeur rotatif, dans le brevet
L'invention concerne un système d'alimentation résolvant de façon avantageuse le problème du dommage affectant l'ensemble rotatif porteur des pistolets de projection des produits devant être appliqués, par l'intermédiaire d'une disposition n'utilisant pas le distributeur rotatif, lequel est fondamentalement endommagé dans les solutions traditionnelles.The invention relates to a feeding system which advantageously solves the problem of the damage affecting the rotary assembly carrying the spray guns of the products to be applied, by means of a disposition which does not use the rotary distributor, which is fundamentally damaged in traditional solutions.
Le système de l'invention consiste à disposer des réservoirs fixes auxquels les produits devant être appliqués sont amenés, par l'intermédiaire de pompes d'alimentation, depuis des réservoirs d'alimentation respectifs, en intégrant en liaison avec lesdits réservoirs fixes des pompes aspirantes à haute pression par l'intermédiaire desquelles les produits sont amenés jusqu'aux pistolets de projection, les pompes aspirantes étant intégrées dans l'ensemble rotatif porteur des pistolets, dans une disposition permettant la rotation des buses d'aspiration desdites pompes aspirantes dans les réservoirs fixes respectifs depuis lesquels produits sont prélevés.The system of the invention consists in arranging fixed tanks to which the products to be applied are fed, via feed pumps, from respective feed tanks, integrating in connection with said fixed tanks suction pumps. at high pressure through which the products are fed to the spray guns, the suction pumps being integrated in the rotary assembly carrying the guns, in a disposition allowing the rotation of the suction nozzles of said suction pumps in the tanks respective fixtures from which products are taken.
On obtient ainsi un système n'utilisant pas de distributeur mais des réservoirs fixes et des pompes aspirantes intégrées dans l'ensemble rotatif porteur des pistolets de projection, les pompes aspirantes fournissant la pression nécessaire aux produits tout en réalisant la propulsion de ceux-ci jusqu'aux pistolets de projection, évitant les problèmes de dommages dont souffrent les distributeurs dans les solutions traditionnelles d'alimentation aux équipements rotatifs d'application de produits par projection par l'intermédiaire de pistolets.A system that does not use a dispenser is thus obtained, but fixed reservoirs and suction pumps integrated into the rotating assembly carrying the spray guns, the suction pumps supplying the pressure necessary for the products while simultaneously propelling them to spray guns, avoiding the problems of damage suffered by distributors in traditional feeding solutions to rotary equipment for application of spray products through guns.
Selon le type de pulvérisation réalisé pour les produits devant être appliqués, en liaison avec les pistolets de projection, certains types de pompes d'aspiration sont installés, qui fournissent la pression nécessaire pour la pulvérisation des produits devant être appliqués. Lesdites pompes d'aspiration tournent avec l'ensemble porteur des pistolets, mais l'ensemble d'alimentation jusqu'aux pompes mentionnées reste statique.Depending on the type of spray performed for the products to be applied, in connection with the spray guns, certain types of suction pumps are installed, which provide the necessary pressure for spraying the products to be applied. Said suction pumps rotate with the carrier assembly of the guns, but the feed assembly to the mentioned pumps remains static.
Les réservoirs grâce auxquels les pompes d'aspiration sont alimentées sont prévus annulaires dans une disposition concentrique, de telle sorte que les produits arrivent auxdits réservoirs uniquement avec la pression de circulation et les pompes aspirantes fournissent la pression nécessaire pour l'application des produits, de telle sorte que les réservoirs d'aspiration ne soient pas soumis à des frottements ni ne doivent supporter des pressions élevées, ne subissant ainsi pas de dommage obligeant à les remplacer.The tanks through which the suction pumps are fed are provided ring-shaped in a concentric arrangement, so that the products arrive at said tanks only with the circulating pressure and the suction pumps provide the necessary pressure for the application of the products, so that the suction tanks are not subjected to friction nor must withstand high pressures, thus not suffering damage requiring replacement.
On obtient ainsi un système d'alimentation pour des équipements rotatifs d'application de produits, avec lequel on obtient des caractéristiques fonctionnelles très avantageuses, de manière que ce système d'alimentation accomplisse la fonction à laquelle il est destiné.A feed system is thus obtained for rotary product application equipment, with which very advantageous functional characteristics are obtained, so that this feed system accomplishes the function for which it is intended.

L'objet de l'invention concerne un système d'alimentation pour des équipements rotatifs d'application de produits de recouvrement, présentant une disposition permettant d'éviter les problèmes occasionnés par le distributeur des produits jusqu'aux pistolets de projection avec les systèmes traditionnels.The object of the invention relates to a feed system for rotary coating application equipment, having a provision to avoid the problems caused by the distributor of products to the spray guns with traditional systems. .
Les systèmes traditionnels d'alimentation pour équipements rotatifs d'application de produits de recouvrement disposent d'un distributeur (1) duquel sortent les différents conduits (2) de fourniture des produits jusqu'aux pistolets (3) de projection, de telle sorte que les produits arrivent au distributeur (1) par autant d'autres conduits (4), depuis les réservoirs de fourniture (5) respectifs, ainsi que cela est illustré sur la
Dans ces systèmes d'application, étant donné que pour la projection les produits devant être appliqués requièrent une pression élevée et que les produits sont généralement très corrosifs, un dommage rapide du distributeur (1) est produit, ce qui entraîne nécessairement son remplacement fréquent, avec les difficultés conséquentes que le démontage et le montage entraînent, étant donné que plusieurs conduits (2 et 4) sont raccordés au distributeur, ainsi que cela est illustré sur la
Selon le système d'alimentation faisant l'objet de la présente invention (
En liaison avec lesdits réservoirs intermédiaires (7) des pompes d'aspiration (8) à haute pression respectives sont installées, qui transfèrent les produits jusqu'aux pistolets (3) de projection, ces derniers étant intégrés dans un ensemble porteur (9) rotatif dans lequel les pompes d'aspiration (8) sont également montées.In connection with said intermediate tanks (7) respective high pressure suction pumps (8) are installed, which transfer the products to the spray guns (3), the latter being integrated into a rotating carrier assembly (9). wherein the suction pumps (8) are also mounted.
De façon particulière, les réservoirs intermédiaires (7) sont de forme circulaire, concentriques entre eux, de telle sorte que les buses d'aspiration des pompes (8) entrent respectivement dans lesdits réservoirs (7), et peuvent se déplacer circulairement dans ceux-ci en étant transportées dans le mouvement de rotation par l'ensemble porteur (9).In particular, the intermediate tanks (7) are circular in shape, concentric with each other, so that the suction nozzles of the pumps (8) respectively enter said tanks (7), and can move circularly in those by being transported in the rotational movement by the carrier assembly (9).
Avec ce système d'alimentation faisant l'objet de l'invention, pour amener les produits jusqu'aux pistolets de projection (3), on n'utilise pas de distributeur tournant avec l'ensemble porteur (9) rotatif et dans lequel la pression nécessaire est fournie aux produits pour la projection d'application, mais les produits sont aspirés dans des réservoirs statiques (7), par l'intermédiaire de pompes (8) fournissant la pression nécessaire pour la projection et intégrées dans le montage sur l'ensemble rotatif (9) porteur des pistolets de projection (3), évitant ainsi les dommages consécutifs à une combinaison de pression et de rotation dans les éléments d'alimentation des produits, ce qui a pour avantage de ne pas devoir réaliser fréquemment des remplacements coûteux des éléments endommagés.With this feed system which is the subject of the invention, in order to bring the products to the spray guns (3), no rotary distributor is used with the rotating carrier assembly (9) and in which the The required pressure is supplied to the products for the application projection, but the products are drawn into static tanks (7), by means of pumps (8) providing the necessary pressure for the projection and integrated in the mounting on the rotary assembly (9) carrying the spray guns (3), thus avoiding damage resulting from a combination of pressure and rotation in the feed elements of the products, which has the advantage of not having to frequently make expensive replacements of the damaged elements.
