The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
  • the Figure 1 is a partial perspective view of a paint spraying device according to the invention;
  • the Figure 2 is a sectional view of the device shown in FIG. Figure 1 ; and
  • the Figure 3 is a top view of the spray device shown in FIG. Figure 1 .

La Figure 1 représente une vue partielle d'un dispositif de pulvérisation de peinture 2.The Figure 1 is a partial view of a paint spraying device 2.

Le dispositif de pulvérisation 2 comporte un corps 4 formant support, dont la partie supérieure comprend une surface 6 sensiblement plane de forme circulaire. Le corps 4 formant support peut notamment être porté par un bras de robot, non représenté, adapté pour déplacer le corps 4.The spraying device 2 comprises a body 4 forming a support, whose upper part comprises a substantially planar surface 6 of circular shape. The body 4 forming a support may in particular be carried by a robot arm, not shown, adapted to move the body 4.

Selon l'invention, au moins deux buses permettant la pulvérisation de la peinture en vue de son application sur la ou les pièce(s) à peindre, non représentée(s), et munies à cet effet de moyens de pulvérisation 16 sont disposées sur la surface plane 6.According to the invention, at least two nozzles for spraying the paint for application to the part (s) to be painted, not shown, and provided for this purpose with spraying means 16 are arranged on the flat surface 6.

Selon l'exemple de réalisation représenté aux Figures 1 à 3, le dispositif de pulvérisation comporte trois buses référencées respectivement 8, 10, 12.According to the exemplary embodiment shown in Figures 1 to 3 , the spraying device comprises three nozzles referenced respectively 8, 10, 12.

De préférence, les buses 8, 10, 12 équipant le dispositif de pulvérisation 2 sont identiques et comportent chacune un corps 14 sensiblement cylindrique raccordé par des moyens d'alimentation en peinture à un réservoir de peinture afin d'alimenter les moyens de pulvérisation 16 de peinture.Preferably, the nozzles 8, 10, 12 fitted to the spraying device 2 are identical and each comprise a substantially cylindrical body 14 connected by paint supply means to a paint tank in order to supply the spraying means 16 of painting.

Chaque buse est montée sur le corps 4 formant support à l'aide d'une entretoise 18 comportant une première face plane 20 fixée sur la partie supérieure du corps 4 et une seconde face 22 supportant la buse. La seconde face 22 est inclinée par rapport à la première face 20, de sorte que la buse montée sur une entretoise 18 est inclinée par rapport à la surface 6.Each nozzle is mounted on the body 4 forming a support with a spacer 18 having a first planar face 20 fixed on the upper part of the body 4 and a second face 22 supporting the nozzle. The second face 22 is inclined relative to the first face 20, so that the nozzle mounted on a spacer 18 is inclined relative to the surface 6.

Les entretoises 18 sont de préférence identiques.The spacers 18 are preferably identical.

La première face plane 20 forme avec la seconde face 22 correspondante un angle α compris entre 20 et 40°. Plus particulièrement, la première face plane 20 et la seconde face 22 inclinée forment entre elles un angle α sensiblement égal à 30°.The first planar face 20 forms with the corresponding second face 22 an angle α of between 20 and 40 °. More particularly, the first plane face 20 and the second inclined face 22 form between them an angle α substantially equal to 30 °.

Afin d'assurer un bon positionnement des buses, chaque seconde face 22 comporte un évidement destiné à accueillir une partie du corps 14 cylindrique de la buse. L'évidemment présente une forme sensiblement complémentaire de celle d'une partie du corps 14 de la buse.To ensure proper positioning of the nozzles, each second face 22 has a recess for receiving a portion of the cylindrical body 14 of the nozzle. The recess has a shape substantially complementary to that of a portion of the body 14 of the nozzle.

Chaque corps de buse possède une première extrémité 24 reliée aux moyens d'alimentation en peinture et une seconde extrémité 26 supportant les moyens de pulvérisation de peinture 16.Each nozzle body has a first end 24 connected to the paint supply means and a second end 26 supporting the paint spraying means 16.

En variante, la première extrémité 24 du corps sensiblement cylindrique peut être libre, les moyens d'alimentation en peinture étant alors disposés dans le corps de l'entretoise 18 de manière à relier le réservoir de peinture aux moyens de pulvérisation 16 de peinture.Alternatively, the first end 24 of the substantially cylindrical body may be free, the paint supply means being then disposed in the body of the spacer 18 so as to connect the paint tank to the spray means 16 of paint.

De préférence, les buses 8, 10, 12 et les entretoises 18 supportant ces dernières sont réparties régulièrement sur la surface 6 supérieure circulaire du corps 4 formant support, de manière à former entre elles un angle de 120°.Preferably, the nozzles 8, 10, 12 and the spacers 18 supporting the latter are regularly distributed on the upper circular surface 6 of the body 4 forming a support, so as to form an angle of 120 ° between them.

Les buses 8, 10, 12 sont disposées sur la partie supérieure 6 du corps 4 de forme circulaire de manière à ce que leur première extrémité 24 soit chacune disposée à proximité du centre de cette partie supérieure. Les extrémités 24 se font ainsi face, tandis que les moyens de pulvérisations 16, supportés par les extrémités 26, sont orientés vers l'extérieur du support 4.The nozzles 8, 10, 12 are disposed on the upper part 6 of the body 4 of circular shape so that their first end 24 is each disposed near the center of this upper part. The ends 24 face each other, while that the spraying means 16, supported by the ends 26, are oriented towards the outside of the support 4.

Chaque buse est disposée de façon identique sur la partie supérieure 6 du corps 4. Chaque buse, fixée sur la face 22 d'une entretoise 18, est inclinée de façon à ce que l'extrémité 26 supportant les moyens de pulvérisations 16 soit surélevée par rapport à l'extrémité 24.Each nozzle is arranged identically on the upper part 6 of the body 4. Each nozzle, fixed on the face 22 of a spacer 18, is inclined so that the end 26 supporting the spraying means 16 is raised by report at the end 24.

Selon l'invention, chaque moyen de pulvérisation 16 est alimenté par un moyen d'alimentation indépendant, c'est-à-dire non relié aux autres moyens d'alimentation assurant l'alimentation en peinture des deux autres buses.According to the invention, each spraying means 16 is fed by an independent supply means, that is to say not connected to the other supply means ensuring the supply of paint to the other two nozzles.

Les moyens d'alimentation sont par exemple formés par un tuyau et une pompe aspirant la peinture du réservoir et l'amenant aux moyens de pulvérisation 16 agencés pour pulvériser la peinture à une pression prédéterminée.The supply means are for example formed by a pipe and a pump sucking the paint from the tank and leading to the spraying means 16 arranged to spray the paint at a predetermined pressure.

De même, chaque moyen de pulvérisation 16 est raccordé à un réservoir de peinture indépendant. Chaque réservoir peut ainsi comprendre parmi une liste non exhaustive les types de peinture suivants : un apprêt, une base ou un vernis.Similarly, each spraying means 16 is connected to an independent paint tank. Each tank can thus include among a non-exhaustive list the following types of paint: a primer, a base or a varnish.

Les peintures utilisées peuvent notamment être de type électrostatique. Ce type de peinture présente la particularité d'être ionisée, tandis que la pièce à peindre est mise à la masse.The paints used may in particular be of the electrostatic type. This type of paint has the distinction of being ionized, while the piece to be painted is grounded.

Les moyens de pulvérisation 16 de chaque buse peuvent être adaptés à la peinture à pulvériser, par exemple en modifiant la pression de pulvérisation ou la taille des orifices de sortie de peinture.The spraying means 16 of each nozzle may be adapted to the spray paint, for example by changing the spray pressure or the size of the paint outlets.

Ainsi, grâce à l'invention un seul bras de robot peut supporter plusieurs buses raccordées chacune à un réservoir de peinture indépendant. Chaque buse peut alors appliquée une couche de peinture différente.Thus, thanks to the invention a single robot arm can support several nozzles each connected to an independent paint tank. Each nozzle can then apply a different layer of paint.

Une telle installation permet de fortement diminuer les coûts d'investissement nécessaires à une installation de peinture.Such an installation makes it possible to greatly reduce the investment costs necessary for a painting installation.

Ainsi, dans le cas représenté aux Figures 1 à 3, où un robot unique comporte trois buses reliées chacune à un réservoir de peinture différent, les coûts sont pratiquement divisés par trois, si l'on compare une telle installation à une installation classique comportant trois robots dont chaque bras est muni d'une seule buse.Thus, in the case shown in Figures 1 to 3 , where a single robot has three nozzles each connected to a different paint tank, the costs are almost divided by three, if we compare such an installation to a conventional installation with three robots each arm has a single nozzle .

L'utilisation d'un robot unique permet alors également de diminuer la consommation énergétique de cette installation.The use of a single robot can also reduce the energy consumption of this installation.

De même, une telle installation permet de fortement réduire la surface nécessaire à son implantation.Similarly, such an installation can greatly reduce the area required for its implementation.

Une telle installation est particulièrement intéressante dans le cas d'installation servant décorer des pièces ou des ensembles de pièces, tel qu'une carrosserie de véhicule automobile, produits en petite série.Such an installation is particularly interesting in the case of installation for decorating parts or sets of parts, such as a body of a motor vehicle, produced in small series.
