Description

Tête de pulvérisation d'un produit tel que de la peinture.Spray head of a product such as paint.
La présente invention concerne les appareils de pulvérisation de produits tels que les peintures, les laques, les émaux, etc., et plus particulièrement les pistolets de pulvérisation.The present invention relates to apparatus for spraying products such as paints, lacquers, enamels, etc., and more particularly spray guns.
On sait que de tels pistolets, qu'ils soient automatiques ou ma- nuels, comportent une tête de pulvérisation, dans laquelle se fait l'amenée du produit à pulvériser et d'un gaz propulseur sous pression, le plus souvent de l'air comprimé. Une telle tête de pulvérisation est constituée par un ensemble de pièces participant à l'atomisation du produit et qui sont principalement : - une buse de pulvérisation de produit ;It is known that such guns, whether automatic or manual, include a spray head, into which the product to be sprayed and a pressurized propellant, most often air, is supplied. compressed. Such a spray head is constituted by a set of parts participating in the atomization of the product and which are mainly: - a product spray nozzle;
- un chapeau de soufflage de gaz ; et- a gas blowing cap; and
- une bague de répartition de gaz, généralement appelée bague déflec- trice, permettant d'alimenter le chapeau en gaz propulseur et éventuellement de répartir ce dernier de manière à obtenir un jet rond ou un jet plat pour le produit pulvérisé.a gas distribution ring, generally called a deflection ring, making it possible to supply the cap with propellant gas and possibly to distribute the latter so as to obtain a round jet or a flat jet for the sprayed product.
Dans les pistolets connus, la buse est généralement fixée sur le corps du pistolet, de sorte que son démontage est relativement complexe.In known guns, the nozzle is generally fixed on the body of the gun, so that its disassembly is relatively complex.
Or, par nature, la buse est une pièce sur laquelle l'opérateur doit intervenir assez fréquemment pour la nettoyer ou la remplacer. De plus, dans les pistolets connus de ce type, du fait même de la fixation de la buse sur le corps de pistolet, il en résulte que le trajet du produit à pulvériser ne peut être lisse, ce qui rend plus difficile le nettoyage.However, by nature, the nozzle is a part on which the operator must intervene frequently enough to clean or replace it. In addition, in known pistols of this type, by the very fact of the attachment of the nozzle on the gun body, it follows that the path of the product to be sprayed cannot be smooth, which makes cleaning more difficult.
Pour remédier à cet inconvénient, le brevet FR-2 788 231 décrit une tête de pulvérisation dans laquelle ladite buse est aisément démonta- ble, tout en assurant au produit à pulvériser un passage lisse au niveau de la buse. Cette dernière tête de pulvérisation comporte : • un corps comprenant un conduit d'alimentation en produit à pulvériser et une face plane annulaire entourant l'extrémité annulaire libre dudit conduit d'alimentation ;To remedy this drawback, patent FR-2 788 231 describes a spray head in which said nozzle is easily removable, while ensuring that the product to be sprayed passes smoothly at the nozzle. This last spray head comprises: • a body comprising a supply pipe for spraying product and an annular planar face surrounding the free annular end of said supply pipe;
• une buse de pulvérisation tubulaire, alimentée en produit à pulvériser à partir dudit conduit d'alimentation et pourvue, à l'une de ses extrémités, d'un orifice de pulvérisation, et, à son extrémité opposée, d'une face annulaire plane ;• a tubular spray nozzle, supplied with product to be sprayed from said supply duct and provided, at one of its ends, with a spray orifice, and, at its opposite end, with a flat annular face ;
" un joint apte à être disposé entre ladite face annulaire plane de ladite buse et ladite extrémité annulaire libre dudit conduit d'alimentation ; " un chapeau de soufflage de gaz ;"a seal capable of being disposed between said flat annular face of said nozzle and said free annular end of said supply duct;" a gas blowing cap;
• une bague de répartition de gaz, assemblée de façon amovible audit chapeau de soufflage de gaz et alimentée en gaz sous pression à partir d'au moins un conduit prévu dans ledit corps et permettant d'alimenter ledit chapeau en gaz de manière homogène et, éventuellement, de ré- partir ledit gaz de manière à faire varier la section du jet dudit produit à la sortie dudit orifice de pulvérisation ; β des moyens de vissage de ladite bague de répartition de gaz sur ledit corps permettant, simultanément :A gas distribution ring, removably assembled to said gas blowing cap and supplied with gas under pressure from at least one duct provided in said body and making it possible to supply said cap with gas in a homogeneous manner, and optionally, distributing said gas so as to vary the cross section of the jet of said product at the outlet of said spray orifice; β means for screwing said gas distribution ring onto said body allowing, simultaneously:
. de solidariser ladite buse de ladite bague de répartition de gaz et dudit corps, et. securing said nozzle to said gas distribution ring and said body, and
. de presser ledit joint entre ladite face annulaire plane de ladite buse et ladite extrémité annulaire libre dudit conduit d'alimentation ; et. pressing said seal between said planar annular face of said nozzle and said free annular end of said supply duct; and
" une bague de retenue, conformée en écrou, pour assembler de façon amovible ledit chapeau de soufflage de gaz et ladite bague de réparti- tion de gaz, ladite bague de retenue coopérant avec un filetage porté par la périphérie externe de ladite bague de répartition de gaz."a retaining ring, shaped as a nut, for removably assembling said gas blowing cap and said gas distribution ring, said retaining ring cooperating with a thread carried by the external periphery of said distribution ring gas.
Ainsi, dans la tête de pulvérisation conforme à ce document FR-2 788 231 , la buse est maintenue par pression entre la bague de répartition et le corps de la tête de pulvérisation et peut être facilement démontable en agissant sur lesdits moyens de serrage. Par ailleurs, le passage du produit entre le conduit de produit à pulvériser, le joint et la buse ne comporte aucune aspérité et peut être lisse.Thus, in the spray head according to this document FR-2 788 231, the nozzle is held by pressure between the distribution ring and the body of the spray head and can be easily removed. by acting on said clamping means. Furthermore, the passage of the product between the product spray pipe, the seal and the nozzle has no roughness and can be smooth.
L'objet de la présente invention est de perfectionner cette tête de pulvérisation pour la rendre encore plus facilement montable et démontable, afin notamment d'en faciliter le nettoyage et, de ce fait, de rendre ladite tête de pulvérisation particulièrement appropriée à la pulvérisation de produits très salissants et/ou visqueux, tels que par exemple les émaux pour carreaux de faïence.

La partie saillante 24A de la bague 4 est ajustée en forme à la chambre centrale 25, dans laquelle elle peut pénétrer. Le chapeau de soufflage 5 comporte de plus une face d'extrémité plane 31 , apte à s'appliquer contre ladite face plane annulaire 24 de la bague 4. A sa périphérie externe, la face 31 comporte un épaulement 32 permettant de retenir ledit chapeau 5 dans la bague de retenue 6 qui comporte à cet effet un épaulement complémentaire 33. Par ailleurs, la bague 6, à l'intérieur de laquelle peut être introduit le chapeau de soufflage 5, comporte un ensemble de rampes quart de tour 34 susceptible de coopérer avec un ensemble de rampes quart de tour complémentaire 35 porté par la couronne annulaire 1 5A.25 provided with a blowing orifice 25A and two symmetrical channels 26, 27 extended by inclined blowing channels 28, 29. The projecting part 24A of the ring 4 is adjusted in shape to the central chamber 25, into which it can penetrate . The blowing cap 5 further comprises a planar end face 31, capable of being applied against said annular planar face 24 of the ring 4. At its external periphery, the face 31 has a shoulder 32 making it possible to retain said cap 5 in the retaining ring 6 which for this purpose has a complementary shoulder 33. Furthermore, the ring 6, inside which the blowing cap 5 can be inserted, comprises a set of quarter-turn ramps 34 capable of cooperating with a set of complementary quarter-turn ramps 35 carried by the annular ring 1 5A.
De ce qui précède, on comprendra aisément que, par vissage d'un quart de tour de la bague de retenue 6 sur la couronne annulaire 15A du corps (grâce à la coopération des ensembles de rampes 34, 35 et à celle des épaulements 32, 33), il est possible, comme cela est montré sur la figure 1 , simultanément :From the above, it will be easily understood that, by screwing a quarter-turn of the retaining ring 6 onto the annular ring 15A of the body (thanks to the cooperation of the sets of ramps 34, 35 and to that of the shoulders 32, 33), it is possible, as shown in FIG. 1, simultaneously:
- de fixer la buse de pulvérisation 3 en prolongement de l'insert tubulaire 7, avec interposition du joint 2 entre les faces planes 13 et 20, ladite buse étant disposée dans l'orifice central 22 et pressée en direction du corps 1 par la coopération des épaulements 19 et 23 ;- to fix the spray nozzle 3 in extension of the tubular insert 7, with interposition of the seal 2 between the planar faces 13 and 20, said nozzle being disposed in the central orifice 22 and pressed towards the body 1 by cooperation shoulders 19 and 23;
- d'appliquer la face plane 21 de la bague 4 contre la face plane 19A de la buse 3 ; et - d'appliquer la face d'appui 31 du chapeau de soufflage 5 contre la face 24 de la bague 4.- Apply the flat face 21 of the ring 4 against the flat face 19A of the nozzle 3; and - applying the bearing face 31 of the blowing cap 5 against the face 24 of the ring 4.
Ainsi, par pression longitudinale, on assemble les éléments 2 à 5 entre eux et on les fixe sur le corps 1 par l'intermédiaire de la bague de retenue 6. En position de montage final (voir la figure 1 ), l'orifice de soufflage 25 est en communication avec le conduit interne 9, tandis que les canaux 26, 27, 28, 29 sont en communication avec le conduit interne 8.Thus, by longitudinal pressure, the elements 2 to 5 are assembled together and fixed to the body 1 by means of the retaining ring 6. In the final mounting position (see FIG. 1), the orifice blowing 25 is in communication with the internal duct 9, while the channels 26, 27, 28, 29 are in communication with the internal duct 8.
Ainsi, le gaz sous pression amené par le conduit 9 (flèche 36) peut propulser le produit à pulvériser amené par le conduit 7 et le gaz sous pression amené par le conduit 8 (flèche 37) peut façonner la section du jet de produit à la sortie de l'orifice 18.Thus, the pressurized gas supplied through line 9 (arrow 36) can propel the spray product supplied through line 7 and the pressurized gas brought through line 8 (arrow 37) can shape the section of the product jet at the outlet 18.
Ainsi, grâce à la présente invention, on obtient une tête de pulvérisation facile à monter et à démonter, ainsi qu'à nettoyer, le joint 2 assu- rant l'étanchéité entre les circuits de gaz sous pression et le circuit de produit à pulvériser. Thus, thanks to the present invention, a spray head is obtained which is easy to assemble and disassemble, as well as to clean, the seal 2 ensuring the seal between the pressurized gas circuits and the product spray circuit. .
