Description

La présente invention concerne les appareils de pulvérisation de produits tels que les peintures, les laques, etc ..., et plus particulièrement les pistolets de pulvérisation.The present invention relates to apparatus for spraying products such as paints, lacquers, etc., and more particularly spray guns.

On sait que de tels pistolets, qu'ils soient automatiques ou manuels, 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 ;
  • une aiguille mobile en translation permettant d'assurer l'ouverture ou la fermeture de l'orifice de pulvérisation de la buse ;
  • un chapeau de soufflage de gaz ; et
  • une bague de répartition de gaz, généralement appelée bague déflectrice, 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.
It is known that such guns, whether automatic or manual, include a spray head, into which is supplied the product to be sprayed and a pressurized propellant, most often compressed air. Such a spray head consists of a set of parts participating in the atomization of the product and which are mainly:
  • a product spray nozzle;
  • a needle movable in translation to ensure the opening or closing of the spray orifice of the nozzle;
  • a gas blowing cap; and
  • a gas distribution ring, generally called a deflector 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 fixée sur le corps du pistolet, de sorte que son démontage est relativement complexe. 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 ces pistolets connus, 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.In known pistols, the nozzle is fixed to the body of the pistol, so its disassembly is relatively complex. Now, by nature, the nozzle is a part on which the operator must intervene enough frequently to clean or replace it. In addition, in these pistols known, by the very fact of the attachment of the nozzle on the gun body, it As a result, the path of the product to be sprayed cannot be smooth, which makes cleaning more difficult.

La présente invention a pour objet de remédier à cet inconvénient et elle concerne une tête de pulvérisation dans laquelle ladite buse est aisément démontable, tout en assurant au produit à pulvériser un passage lisse au niveau de la buse.The object of the present invention is to remedy this drawback and it relates to a spray head in which said nozzle is easily removable, while ensuring the product to spray a passage smooth at the nozzle.

A cette fin, selon l'invention, la tête de pulvérisation pour appareil destiné à pulvériser un produit, tel que peinture ou laque, comportant un corps auquel sont rapportés :

  • une buse de pulvérisation tubulaire, alimentée en produit à pulvériser à partir d'un conduit prévu dans ledit corps et pourvue à l'une de ses extrémités d'un orifice de pulvérisation, dont l'ouverture et la fermeture sont commandées par une aiguille mobile ;
  • un chapeau de soufflage de gaz ; et
  • une bague de répartition de gaz, alimentée en gaz sous pression à partir d'au moins un conduit prévu dans ledit corps et permettant d'alimenter ledit chapeau en gaz propulseur de manière homogène et, éventuellement, de répartir ledit gaz de manière à faire varier la section du jet dudit produit à la sortie dudit orifice de pulvérisation,
est remarquable en ce que :
  • ledit corps comporte une face plane, dans laquelle débouche ledit conduit d'alimentation en produit à pulvériser ;
  • ladite buse comporte, du côté opposé audit orifice de pulvérisation, une face annulaire plane ;
  • un joint est prévu pour pouvoir être disposé entre ladite face annulaire de la buse et l'extrémité libre dudit conduit d'alimentation en produit à pulvériser ;
  • ladite bague de répartition de gaz :
    • comporte une face d'extrémité plane ; et
    • est apte à guider et à maintenir ladite buse ; et
  • des moyens de serrage sont prévus pour, simultanément :
    • presser l'une contre l'autre la face d'extrémité plane de ladite bague de répartition et la face plane dudit corps ; et
    • presser ledit joint entre la face annulaire plane de la buse et l'extrémité libre dudit conduit d'alimentation en produit à pulvériser.
To this end, according to the invention, the spray head for an apparatus intended to spray a product, such as paint or lacquer, comprising a body to which are reported:
  • a tubular spray nozzle, supplied with product to be sprayed from a duct provided in said body and provided at one of its ends with a spray orifice, the opening and closing of which are controlled by a movable needle ;
  • a gas blowing cap; and
  • a gas distribution ring, supplied with pressurized gas from at least one conduit provided in said body and making it possible to supply said cap with propellant gas in a homogeneous manner and, optionally, distributing said gas so as to vary the section of the jet of said product at the outlet of said spray orifice,
is remarkable in that:
  • said body has a flat face, into which opens said supply pipe for spraying product;
  • said nozzle comprises, on the side opposite to said spray orifice, a planar annular face;
  • a seal is provided so that it can be disposed between said annular face of the nozzle and the free end of said supply pipe for spraying;
  • said gas distribution ring:
    • has a planar end face; and
    • is able to guide and maintain said nozzle; and
  • clamping means are provided for, simultaneously:
    • pressing one against the other the flat end face of said distribution ring and the flat face of said body; and
    • pressing said seal between the flat annular face of the nozzle and the free end of said supply pipe for spraying product.

Ainsi, dans la tête de pulvérisation conforme à la présente invention, 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. Enfin, du fait qu'il n'existe aucun joint intermédiaire entre la bague de répartition et ledit corps, le montage et le démontage de la tête de pulvérisation sont particulièrement simplifiés.Thus, in the spray head according to the present invention, the nozzle is held by pressure between the distribution ring and the body of the spray head and can be easily disassembled by acting on said clamping means. In addition, the passage of the product between the spray hose, the seal and the nozzle no roughness and can be smooth. Finally, because there is no joint intermediate between the distribution ring and said body, mounting and disassembly of the spray head are particularly simplified.

Dans un mode de réalisation avantageux, la tête de pulvérisation conforme à l'invention est telle que :

  • ladite face plane dudit corps est pourvue d'une saillie tubulaire, dans laquelle débouche ledit conduit d'alimentation en produit à pulvériser, l'extrémité annulaire libre de ladite saillie étant plane et parallèle à ladite face plane dudit corps et formant l'extrémité libre dudit conduit d'alimentation en produit à pulvériser ; et
  • ladite bague de répartition de gaz comporte un orifice central traversant, dans lequel peut être guidée et maintenue ladite buse et grâce auquel ladite bague de répartition peut être montée sur ladite saillie tubulaire.
In an advantageous embodiment, the spray head according to the invention is such that:
  • said flat face of said body is provided with a tubular projection, into which opens said duct for supplying spray product, the free annular end of said projection being planar and parallel to said flat face of said body and forming the free end said product supply pipe to be sprayed; and
  • said gas distribution ring has a central through hole, in which can be guided and held said nozzle and by which said distribution ring can be mounted on said tubular projection.

Ainsi, ladite saillie tubulaire sert au centrage de la bague de répartition par rapport au corps de la tête de pulvérisation.Thus, said tubular projection is used for centering the distribution ring relative to the body of the spray head.

De plus, dans un mode de réalisation particulier, lesdits moyens de serrage peuvent être réalisés de manière simple, grâce à des filetages coopérants, respectivement portés par la saillie tubulaire et par l'orifice central de la bague de répartition. In addition, in a particular embodiment, said means tightening can be done in a simple way, thanks to threads cooperating, respectively carried by the tubular projection and by the orifice center of the distribution ring.

Dans un tel mode de réalisation, pour assurer l'alimentation en produit à pulvériser et en gaz propulseur à partir dudit corps, on peut faire en sorte que :

  • ledit conduit d'alimentation en gaz débouche dans une gorge circulaire, pratiquée dans ladite face plane dudit corps, concentriquement à ladite saillie tubulaire ;
  • la face d'extrémité de ladite bague de répartition de gaz est pourvue d'une gorge circulaire, concentrique audit orifice central ; et
  • lesdites gorges circulaires dudit corps et de ladite bague de répartition communiquent l'une avec l'autre lorsque la face plane du corps et la face d'extrémité plane de la bague de répartition sont appliquées l'une contre l'autre.
In such an embodiment, to ensure the supply of spray product and propellant gas from said body, it is possible to ensure that:
  • said gas supply conduit opens into a circular groove, formed in said flat face of said body, concentric with said tubular projection;
  • the end face of said gas distribution ring is provided with a circular groove, concentric with said central orifice; and
  • said circular grooves of said body and of said distribution ring communicate with each other when the planar face of the body and the planar end face of the distribution ring are applied against one another.

Par ailleurs, on sait également que dans les pistolets connus, le chapeau d'air est généralement vissé sur la tête de pulvérisation. Or, le chapeau d'air est également, par nature, une pièce sur laquelle l'opérateur doit intervenir assez fréquemment, soit pour orienter le jet de peinture, soit pour le nettoyer, soit pour le remplacer. Par suite, le système de fixation du chapeau d'air sur le pistolet est vulnérable et sa destruction ou son altération entraíne inévitablement un remplacement pur et simple de la tête de pulvérisation ou de la totalité du corps, ce qui se traduit par une opération coûteuse.Furthermore, it is also known that in known pistols, the air cap is usually screwed onto the spray head. However, the air cap is also, by nature, a part on which the operator must intervene quite frequently, either to orient the spray of paint, either to clean it or to replace it. As a result, the system of fixing the air cap on the gun is vulnerable and its destruction or its alteration inevitably leads to an outright replacement of the spray head or the entire body, which results in an expensive operation.

Pour remédier à cet inconvénient, la présente invention prévoit de plus que ledit chapeau de soufflage de gaz est monté solidaire, de façon amovible, de ladite bague de répartition de gaz.To overcome this drawback, the present invention provides more than said gas blowing cap is mounted integral, so removable from said gas distribution ring.

Ainsi, dans la présente invention, ladite bague de répartition des gaz est utilisée simultanément pour la fixation de la buse et pour celle du chapeau de soufflage de gaz. Thus, in the present invention, said distribution ring of gas is used simultaneously for fixing the nozzle and for fixing the gas blowing cap.

De préférence, ledit chapeau de soufflage de gaz est monté sur ladite bague de répartition par l'intermédiaire d'un écrou coopérant avec un filetage porté par la périphérie externe de la bague.Preferably, said gas blowing cap is mounted on said distribution ring by means of a nut cooperating with a thread carried by the outer periphery of the ring.

La tête de pulvérisation conforme à la présente invention peut former une seule pièce monolithique avec ledit appareil de pulvérisation. En variante, elle peut être rapportée audit appareil.The spray head according to the present invention can forming a single monolithic part with said spraying apparatus. Alternatively, it can be added to said device.

Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. Sur ces figures, des références identiques désignent des éléments semblables.The figures in the accompanying drawing will make it clear how the invention can be realized. In these figures, identical references denote similar elements.

La tête de pulvérisation conforme à la présente invention et montrée sur les figures 1 et 2 comporte un corps 1, un joint 2, une buse de pulvérisation 3, une bague de répartition de gaz 4, un chapeau de soufflage de gaz 5 et un écrou 6.The spray head according to the present invention and shown in Figures 1 and 2 has a body 1, a seal 2, a nozzle spray 3, a gas distribution ring 4, a blowing cap gas 5 and a nut 6.

Le corps 1 de cette tête de pulvérisation comporte un conduit interne 7 d'alimentation en produit à pulvériser, ainsi que deux conduits internes 8 et 9 d'alimentation en air comprimé. Le corps 1 comporte une face plane 10 pourvue d'une saillie tubulaire 11, dont le conduit interne 12 est en communication avec le conduit d'alimentation en produit 7. La périphérie externe de la saillie tubulaire 11 porte un filetage 13. Les conduits 8 et 9 débouchent respectivement dans des gorges 14 et 15 circulaires, concentriques à la saillie tubulaire 11.The body 1 of this spray head has an internal duct 7 supply of spray product, as well as two conduits internal 8 and 9 compressed air supply. The body 1 has a flat face 10 provided with a tubular projection 11, the internal duct of which 12 is in communication with the product supply duct 7. The outer periphery of the tubular projection 11 carries a thread 13. The conduits 8 and 9 open respectively into circular grooves 14 and 15, concentric with the tubular projection 11.

Une aiguille 16, coaxiale à la saillie tubulaire 11, est montée coulissante en translation le long de son axe longitudinal, comme cela est illustré par une double flèche. A needle 16, coaxial with the tubular projection 11, is slidably mounted in translation along its longitudinal axis, as is illustrated by a double arrow.

L'extrémité annulaire libre 17 de la saillie 11 est plane et parallèle à la face plane 10 du corps 1. La buse 3 est de forme sensiblement tubulaire et elle est pourvue à l'une de ses extrémités d'un orifice de pulvérisation 18. A son extrémité opposée, elle comporte un épaulement 19 définissant une face annulaire plane 20.The free annular end 17 of the projection 11 is flat and parallel to the flat face 10 of the body 1. The nozzle 3 is of substantially tubular shape and it is provided at one of its ends with a spray orifice 18. At its opposite end, it has a shoulder 19 defining a flat annular face 20.

Le joint 2 est destiné à être interposé entre l'extrémité annulaire libre 17 de la saillie 11 et la face annulaire plane 20 de la buse 3.The seal 2 is intended to be interposed between the annular end free 17 of the projection 11 and the planar annular face 20 of the nozzle 3.

La bague de répartition de gaz 4 comporte une face d'extrémité plane 21 susceptible de s'appliquer contre la face plane 10 du corps 1. Cette bague comporte de plus un orifice central 22 pourvu d'un épaulement 23. La buse 3 peut être introduite à frottement doux dans l'orifice central 22, son épaulement 19 venant en butée contre l'épaulement 23 de ce dernier. La partie de l'orifice central 22, élargie par ledit épaulement 23, porte un filetage interne 24, apte à coopérer avec le filetage 13 de la saillie 11.The gas distribution ring 4 has an end face plane 21 capable of being applied against the flat face 10 of the body 1. This ring also has a central orifice 22 provided with a shoulder 23. The nozzle 3 can be introduced with gentle friction into the orifice central 22, its shoulder 19 abutting against the shoulder 23 of the last. The part of the central orifice 22, enlarged by said shoulder 23, has an internal thread 24, capable of cooperating with the thread 13 of the projection 11.

Dans la bague 4 sont prévues des gorges 25 et 26 débouchant dans ladite face plane 21 et respectivement reliées à des canaux 27 et 28. A la périphérie de la bague 4 est prévu un filetage 29. Du côté opposé à la face plane 21, la bague 4 comporte une face circulaire de butée 30 pour le chapeau de soufflage de gaz 5.In the ring 4 are provided grooves 25 and 26 opening in said planar face 21 and respectively connected to channels 27 and 28. At the periphery of the ring 4 is provided a thread 29. On the opposite side at the planar face 21, the ring 4 has a circular abutment face 30 for the gas blowing cap 5.

Celui-ci comporte une chambre centrale 31 pourvue d'un orifice de soufflage 31A et de deux canaux symétriques 32 prolongés de canaux inclinés de soufflage 33, ainsi qu'une face d'appui 34 susceptible de s'appliquer contre la face 30 de la bague 4.This comprises a central chamber 31 provided with an orifice supply 31A and two symmetrical channels 32 extended by channels inclined blowing 33, as well as a bearing face 34 capable of apply against the face 30 of the ring 4.

Le chapeau de soufflage 5 comporte, du côté opposé aux canaux 33, un épaulement 35 permettant de retenir ledit chapeau dans l'écrou 6 qui comporte à cet effet un épaulement complémentaire 36. Par ailleurs, l'écrou 6, à l'intérieur duquel peut être introduit la bague de répartition de gaz 5, comporte un filetage interne 37 susceptible de coopérer avec le filetage externe périphérique 29 de la bague de répartition de gaz 4.The blowing cap 5 has, on the side opposite the channels 33, a shoulder 35 for retaining said cap in the nut 6 which has for this purpose a complementary shoulder 36. Furthermore, the nut 6, inside which the distribution ring of the gas 5, has an internal thread 37 capable of cooperating with the peripheral external thread 29 of the gas distribution ring 4.

De ce qui précède, on comprendra aisément que, par vissage de la bague de répartition de gaz 4 sur la saillie tubulaire 11 (grâce à la coopération des filetages 13 et 24), il est possible, simultanément :

  • de fixer la buse de pulvérisation 3 en prolongement de la saillie tubulaire 11, avec interposition du joint 2 entre les faces planes 17 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 ;
  • d'appliquer la face d'extrémité plane 21 de la bague 4 contre la face plane 10 du corps 1, les gorges 14 et 15 étant alors respectivement en regard des gorges 25 et 26.
From the above, it will be easily understood that, by screwing the gas distribution ring 4 onto the tubular projection 11 (thanks to the cooperation of the threads 13 and 24), it is possible, simultaneously:
  • to fix the spray nozzle 3 as an extension of the tubular projection 11, with interposition of the seal 2 between the planar faces 17 and 20, said nozzle being disposed in the central orifice 22 and pressed towards the body 1 by the cooperation of the shoulders 19 and 23;
  • applying the flat end face 21 of the ring 4 against the flat face 10 of the body 1, the grooves 14 and 15 then being respectively opposite the grooves 25 and 26.

Par ailleurs, par vissage de l'écrou 6 sur la bague 4 (grâce à la coopération des filetages 29 et 37), on peut fixer le chapeau de soufflage 5 sur ladite bague 4, ledit chapeau étant entouré par ledit écrou et pressé par sa face d'appui 34 contre la face de butée 30 de ladite butée 4, grâce à la coopération des épaulements 35 et 36. En position de montage final, les canaux 27 sont en regard des canaux 32 et donc en communication avec les canaux de soufflage 33, tandis que les canaux 28 débouchent dans la chambre centrale 31, dont l'orifice de soufflage 31A entoure l'orifice de pulvérisation 18 de la buse 3.Furthermore, by screwing the nut 6 onto the ring 4 (thanks to the cooperation of threads 29 and 37), the blowing cap can be fixed 5 on said ring 4, said cap being surrounded by said nut and pressed by its bearing face 34 against the abutment face 30 of said abutment 4, thanks to the cooperation of the shoulders 35 and 36. In the final mounting position, channels 27 are opposite channels 32 and therefore in communication with the blowing channels 33, while the channels 28 open out in the central chamber 31, the blowing orifice 31A of which surrounds the orifice spraying nozzle 18.

Ainsi, le gaz sous pression amené par le conduit 9 peut propulser le produit à pulvériser amené par le conduit 7 et le gaz sous pression amené par le conduit 8 peut façonner la section du jet de produit à la sortie de l'orifice 18.Thus, the pressurized gas brought in through line 9 can propel the product to be sprayed brought by line 7 and the gas under pressure brought by the conduit 8 can shape the section of the product jet at the outlet orifice 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 assurant 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 easy to assemble and disassemble, as well as to clean, joint 2 ensuring the seal between the pressurized gas circuits and the product circuit to spray.
