Description

La présente invention concerne un dispositif de nettoyage d'objet, en particulier de pistolet à peinture, équipé d'un circuit de circulation de fluide, ainsi qu'une installation de nettoyage intégrant au moins un tel dispositif de nettoyage.The present invention relates to an object cleaning device, in particular a spray gun, equipped with a fluid circulation circuit, and a cleaning installation incorporating at least one such cleaning device.

L'invention concerne, plus particulièrement, un dispositif de nettoyage comportant au moins une buse de lavage présentant, côté corps, un orifice d'alimentation en fluide de nettoyage et, côté tête, un embout de raccordement au circuit de circulation de fluide de l'objet à nettoyer, cet embout de raccordement étant muni d'un orifice d'évacuation de fluide de nettoyage de ladite buse.The invention relates, more particularly, to a cleaning device comprising at least one washing nozzle having, on the body side, a cleaning fluid supply orifice and, on the head side, a connecting piece to the fluid circulation circuit of the fluid. object to be cleaned, this connection piece being provided with a cleaning fluid discharge orifice of said nozzle.

Un tel dispositif de nettoyage est notamment décrit dans les brevetsSuch a cleaning device is in particular described in the patents GB-2.182.266GB-2,182,266 ,, EP-1.602.412EP-1602412 etand EP-1.386.671EP-1386671 ..

Certains objets, tels que les pistolets à peinture, nécessitent, après utilisation, du fait de la présence d'un circuit de circulation de fluide interne audit objet, tel qu'un circuit de circulation de peinture, un nettoyage à la fois interne et externe. En effet, il est nécessaire de procéder, généralement par brossage, au nettoyage de la surface extérieure de l'objet, susceptible d'avoir été souillée par les manipulations ou les projections. Il est également nécessaire de procéder au nettoyage du circuit intérieur de l'objet en faisant circuler à l'intérieur dudit circuit un fluide de nettoyage sous pression.Some objects, such as spray guns, require, after use, because of the presence of a fluid circulation circuit internal to said object, such as a paint circulation circuit, cleaning both internally and externally. . Indeed, it is necessary to proceed, usually by brushing, the cleaning of the outer surface of the object, may have been soiled by manipulation or projections. It is also necessary to clean the internal circuit of the object by circulating within said circuit a pressure cleaning fluid.

Jusqu'à présent, chaque opération de nettoyage est effectuée à l'aide d'un dispositif de nettoyage qui lui est propre. Il est donc nécessaire de disposer d'une part, d'une brosse raccordable à un circuit de fluide de nettoyage sous pression, d'autre part, d'une buse raccordable à un circuit de fluide de nettoyage sous pression, le raccordement de la brosse nécessitant, soit le débranchement de la buse et vice-versa, soit l'ajout sur l'installation de nettoyage d'un circuit d'alimentation séparé pour la brosse et pour la buse. Il en résulte de nombreuses manipulations, source de perte de temps, d'erreurs de branchement et de gaspillage en fluide de nettoyage, du fluide de nettoyage s'échappant à chaque changement d'accessoire de nettoyage ou encore un surcoût pour l'installation de lavage.Until now, each cleaning operation is carried out using a cleaning device of its own. It is therefore necessary to have, on the one hand, a brush connectable to a pressurized cleaning fluid circuit, on the other hand, a nozzle that can be connected to a pressurized cleaning fluid circuit, the connection of the brush requiring either the disconnection of the nozzle and vice-versa, or the addition to the cleaning installation of a separate supply circuit for the brush and the nozzle. It results from many manipulations, a source of loss of time, errors of connection and waste of cleaning fluid, cleaning fluid escaping with each change of cleaning accessory or an additional cost for the washing installation.

Un but de la présente invention est donc de proposer un dispositif de nettoyage d'objets du type précité dont la conception permet de nettoyer à la fois l'intérieur et l'extérieur d'un objet équipé d'un circuit de circulation de fluide, sans avoir à déconnecter le dispositif de sa source d'alimentation en fluide de nettoyage.An object of the present invention is therefore to provide an object cleaning device of the aforementioned type whose design makes it possible to clean both the inside and the outside of an object equipped with a fluid circulation circuit, without having to disconnect the device from its cleaning fluid supply source.

Un autre but de la présente invention est de proposer un dispositif de nettoyage dont la conception permet de réduire les risques de projection de fluide de nettoyage sur l'opérateur pendant l'opération de lavage du circuit de circulation de fluide de l'objet à nettoyer.Another object of the present invention is to propose a cleaning device whose design makes it possible to reduce the risks of projection of cleaning fluid on the operator during the washing operation of the fluid circulation circuit of the object to be cleaned. .

Un autre but de la présente invention est de proposer un dispositif de nettoyage dont la conception permet de réduire le nombre de composants nécessaires au nettoyage de l'intérieur et de l'extérieur de l'objet.Another object of the present invention is to provide a cleaning device whose design reduces the number of components needed for cleaning the inside and outside of the object.

Un autre but de la présente invention est de proposer une installation de nettoyage dont la conception du dispositif de nettoyage permet de réduire le coût de l'ensemble.Another object of the present invention is to provide a cleaning installation whose design of the cleaning device reduces the cost of the assembly.

A cet effet, l'invention a pour objet un dispositif de nettoyage d'objet, en particulier de pistolet à peinture, équipé d'un circuit de circulation de fluide, ce dispositif de nettoyage comportant, au moins une buse de lavage présentant côté corps, un orifice d'alimentation en fluide de nettoyage, et, côté tête, un embout de raccordement au circuit de circulation de fluide de l'objet à nettoyer, cet embout de raccordement étant muni d'un orifice d'évacuation de fluide de nettoyage de ladite buse, caractérisé en ce que le dispositif comporte en outre, une brosse formée d'une monture portant des poils aptes à entourer la tête de buse en délimitant un logement tubulaire de réception de ladite tête, brosse et buse étant animées d'un déplacement relatif axial pour passer d'une position dite de nettoyage de l'intérieur de l'objet à nettoyer, dans laquelle l'embout de raccordement de la buse fait, au moins partiellement, saillie du logement de poils pour être raccordé à l'entrée du circuit d'alimentation de l'objet à nettoyer, à une position dite de nettoyage de l'extérieur de l'objet, dans laquelle la buse s'escamote à l'intérieur dudit logement formé par les poils aptes à venir en contact direct de la surface de l'objet à nettoyer.For this purpose, the subject of the invention is an object cleaning device, in particular a spray gun, equipped with a fluid circulation circuit, this cleaning device comprising at least one washing nozzle having a body side , a cleaning fluid supply orifice, and, on the head side, a connection piece to the fluid circulation circuit of the object to be cleaned, this connection piece being provided with a cleaning fluid discharge orifice. of said nozzle, characterized in that the device further comprises a brush formed of a frame carrying bristles adapted to surround the nozzle head delimiting a tubular receiving housing of said head, brush and nozzle being moved relative axial to move from a so-called cleaning position of the interior of the object to be cleaned, wherein the nozzle connecting tip is at least partially protruding from the housing of hair to be connected to the inlet of the supply circuit of the object to be cleaned, to a so-called cleaning position of the outside of the object, in which the nozzle retracts inside said housing formed by the bristles adapted to come into direct contact with the surface of the object to be cleaned.

Le déplacement relatif axial entre brosse et buse permet, de manière aisée, sans avoir à déconnecter le dispositif de nettoyage de sa source d'alimentation en fluide de nettoyage, de passer d'une phase de nettoyage de l'intérieur de l'objet à une phase de nettoyage de l'extérieur de l'objet par brossage et inversement.The relative axial displacement between the brush and the nozzle makes it possible, in an easy manner, without having to disconnect the cleaning device from its cleaning fluid supply source, to go from a cleaning phase of the interior of the object to a cleaning phase of the outside of the object by brushing and vice versa.

De préférence, en position de nettoyage de l'intérieur de l'objet à nettoyer, dans laquelle l'embout de raccordement de la buse fait, au moins partiellement, saillie du logement de poils pour être raccordé à l'entrée du circuit d'alimentation de l'objet à nettoyer, lesdits poils forment, dans ladite position, un écran aux projections issues de la zone de raccordement entre buse et objet à nettoyer.Preferably, in the cleaning position of the interior of the object to be cleaned, in which the nozzle connecting piece makes, at least partially, protruding from the pile housing to be connected to the inlet of the circuit supplying the object to be cleaned, said bristles form, in said position, a projection screen from the connection zone between the nozzle and the object to be cleaned.

Grâce à la présence des poils de la brosse, formant une haie ou rideau de poils autour de l'embout de raccordement de la buse, à l'état raccordé de ladite buse au circuit de circulation de fluide interne de l'objet à nettoyer, les risques de projection de fluide de nettoyage en direction de l'opérateur au niveau de cette zone de raccordement généralement non parfaitement étanche, sont réduits.Thanks to the presence of the bristles of the brush, forming a hedge or curtain of bristles around the tip of the nozzle connection, in the connected state of said nozzle to the internal fluid circulation circuit of the object to be cleaned, the risks of spraying cleaning fluid towards the operator at this connection zone, which is generally not perfectly tight, are reduced.

L'invention a encore pour objet une installation de nettoyage d'objet équipé d'un circuit de circulation de fluide, ladite installation comportant au moins une cuve de traitement de fluide de nettoyage équipée d'au moins un orifice de sortie de fluide traité sous pression, et un dispositif de nettoyage interposable entre la cuve de traitement de fluide et l'objet à nettoyer, ce dispositif de nettoyage étant raccordé, en entrée, à l'orifice de sortie de la cuve de traitement, et raccordable en sortie, à l'entrée du circuit de circulation de fluide de l'objet à nettoyer, ladite cuve de traitement comportant en outre, au moins un orifice d'entrée de fluide apte à recueillir le fluide sortant de l'orifice de sortie du circuit de fluide de l'objet à nettoyer caractérisée en ce que le dispositif de nettoyage est du type précité.The subject of the invention is also an object cleaning installation equipped with a fluid circulation circuit, said installation comprising at least one cleaning fluid treatment tank equipped with at least one fluid outlet orifice treated under pressure, and an interposable cleaning device between the fluid treatment tank and the object to be cleaned, this cleaning device being connected, at the inlet, to the outlet of the treatment vessel, and connectable at the outlet, at the inlet of the fluid circulation circuit of the object to be cleaned, said treatment tank further comprising at least one fluid inlet orifice capable of collecting the fluid leaving the outlet orifice of the fluid circuit of the object to be cleaned, characterized in that the cleaning device is of the aforementioned type.

L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :

  • La figure 1 représente une vue en coupe d'un dispositif de nettoyage conforme à l'invention dans la position de nettoyage de l'extérieur de l'objet par brossage;
  • La figure 2 représente une vue en coupe d'un dispositif de nettoyage conforme à l'invention en position de nettoyage de l'intérieur de l'objet à nettoyer ;
  • La figure 3 représente une vue en perspective d'un dispositif de nettoyage conforme à l'invention et
  • La figure 4 représente une vue en perspective d'une installation de nettoyage d'un pistolet à peinture à l'état non raccordé de la buse au pistolet.
The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
  • The figure 1 is a sectional view of a cleaning device according to the invention in the cleaning position of the outside of the object by brushing;
  • The figure 2 is a sectional view of a cleaning device according to the invention in the cleaning position of the interior of the object to be cleaned;
  • The figure 3 represents a perspective view of a cleaning device according to the invention and
  • The figure 4 is a perspective view of a cleaning installation of a paint sprayer in the non-connected state of the nozzle to the gun.

Comme mentionné ci-dessus, le dispositif de nettoyage, objet de l'invention, est plus particulièrement destiné au nettoyage d'objets équipés d'un circuit intérieur de circulation de fluide.As mentioned above, the cleaning device, which is the subject of the invention, is more particularly intended for cleaning objects equipped with an internal circuit for circulating fluid.

L'invention sera plus particulièrement décrite ci-après dans le cas d'une application au nettoyage de pistolet à peinture à actionnement pneumatique, de tels pistolets comportant d'une part une entrée d'air représenté en 21 aux figures, d'autre part un circuit de circulation de peinture. La peinture entraînée pneumatiquement est expulsée dudit pistolet à travers un orifice représenté en 22 aux figures. Cet orifice correspond également à la sortie du fluide de nettoyage, ce fluide de nettoyage étant introduit dans le pistolet par l'intermédiaire d'un orifice représenté en 24 aux figures. La peinture, de même que le fluide de nettoyage, circulent donc à l'intérieur du pistolet entre les orifices 24 et 22.The invention will be more particularly described below in the case of an application to the cleaning of spray gun with pneumatic actuation, such guns having on the one hand an air inlet shown in 21 in the figures, on the other hand a paint circulation circuit. The pneumatically driven paint is expelled from said gun through an orifice shown in FIG. 22 in the figures. This orifice also corresponds to the outlet of the cleaning fluid, this cleaning fluid being introduced into the gun through an orifice shown at 24 in FIGS. The paint, as well as the cleaning fluid, therefore circulate inside the gun between the orifices 24 and 22.

Le dispositif 1 de nettoyage comporte, pour le lavage d'un tel pistolet 20, au moins une buse 2 de lavage présentant, côté corps 3, un orifice 4 d'alimentation en fluide de nettoyage raccordable à une source d'alimentation en fluide de nettoyage, et côté tête 5, un embout 6 de raccordement au circuit de circulation de fluide de l'objet à nettoyer. Cet embout 6 de raccordement est muni d'un orifice 7 d'évacuation de fluide de nettoyage de ladite buse 2.The cleaning device 1 comprises, for washing such a gun 20, at least one washing nozzle 2 having, on the body side 3, a cleaning fluid supply port 4 connectable to a fluid supply source. cleaning, and head 5, a nozzle 6 for connection to the fluid circulation circuit of the object to be cleaned. This connection piece 6 is provided with a cleaning fluid discharge orifice 7 for the said nozzle 2.

Dans les exemples représentés, cet embout 6 de raccordement affecte une forme générale conique, l'orifice 7 d'évacuation du fluide de nettoyage étant positionné au sommet dudit cône. Cet embout 6 de raccordement conique vient se loger par emboîtement à l'intérieur de l'orifice 24 d'entrée de circulation du fluide de l'objet 20, en l'occurrence du pistolet 20, à nettoyer.In the examples shown, this connecting piece 6 has a generally conical shape, the discharge orifice 7 of the cleaning fluid being positioned at the top of said cone. This tip 6 conical connection is housed by interlocking inside the orifice 24 of the fluid circulation inlet of the object 20, in this case the gun 20, to clean.

La forme conique de l'embout 6 de raccordement permet à ce dernier de s'adapter à différents diamètres d'entrée du circuit de circulation de fluide d'objets à nettoyer.The conical shape of the connecting piece 6 allows the latter to adapt to different inlet diameters of the fluid circulation circuit of objects to be cleaned.

Du fait d'un montage à emboîtement conique de l'embout 6 de raccordement dans l'orifice de l'objet 20 à nettoyer, l'étanchéité n'est pas parfaite au niveau de ladite zone de raccordement.Because of a tapered fitting of the connection piece 6 in the orifice of the object 20 to be cleaned, the seal is not perfect at said connection area.

Pour résoudre ce problème, le dispositif 1 comporte, en outre, une brosse 8 formée d'une monture 9 portant des poils 10 apte à entourer la tête 5 de buse en délimitant un logement 11 tubulaire de réception de ladite tête 5. Brosse 8 et buse 2 sont ainsi animées d'un déplacement relatif axial pour passer d'une position dite de nettoyage de l'intérieur de l'objet 20 à nettoyer, dans laquelle l'embout de raccordement de la buse fait au moins partiellement saillie du logement 11 de poils pour être raccordé à l'entrée du circuit d'alimentation de l'objet 20 à nettoyer, lesdits poils 10 formant dans ladite position un écran aux projections éventuelles issues de la zone de raccordement entre buse 2 et objet 20 à nettoyer, à une position dite de nettoyage de l'extérieur de l'objet 20 dans laquelle la buse 2 s'escamote à l'intérieur dudit logement 11 formé par les poils 10, ces poils 10 étant alors aptes à venir en contact direct de la surface de l'objet 20 à nettoyer pour réaliser un nettoyage par brossage de ladite surface.To solve this problem, the device 1 further comprises a brush 8 formed of a frame 9 carrying bristles 10 capable of surrounding the nozzle head 5 delimiting a tubular receiving housing 11 of said head 5. Brush 8 and nozzle 2 are thus animated with a relative axial displacement to move from a so-called cleaning position of the interior of the object 20 to be cleaned, in which the connection end of the nozzle is at least partially projecting from the housing 11 bristles to be connected to the inlet of the supply circuit of the object 20 to be cleaned, said bristles 10 forming in said position a screen for any projections from the connection area between nozzle 2 and object 20 to be cleaned at a position called cleaning the outside of the object 20 in which the nozzle 2 retracts inside said housing 11 formed by the bristles 10, these bristles 10 then being able to come into direct contact with the surface of the object 20 to be cleaned for cleaning by brushing said surface.

La position dite de nettoyage de l'intérieur de l'objet à nettoyer correspond à la figure 2, tandis que la position de nettoyage de l'extérieur de l'objet à nettoyer correspond à la figure 1. Dans la position dite de nettoyage représentée à la figure 2, les poils sont de longueur suffisante pour que leurs extrémités s'étendent au droit de l'emboîture ou zone de raccordement entre embout 7 et circuit d'alimentation en fluide de l'objet 20 à nettoyer.The so-called cleaning position of the interior of the object to be cleaned corresponds to the figure 2 , while the cleaning position of the outside of the object to be cleaned corresponds to the figure 1 . In the so-called cleaning position represented in figure 2 , the bristles are of sufficient length so that their ends extend to the right of the socket or connection area between the nozzle 7 and the fluid supply circuit of the object 20 to be cleaned.

Dans la position de nettoyage de l'extérieur de l'objet correspondant à la figure 1, dans laquelle la buse 2 est escamotée à l'intérieur du logement 11 formé par les poils 10 de la brosse 8, la tête 5 de buse 2 s'étend à l'intérieur ou en retrait du logement 11 formé par les poils 10 de la brosse 8.In the cleaning position of the outside of the object corresponding to the figure 1 , in which the nozzle 2 is retracted inside the housing 11 formed by the bristles 10 of the brush 8, the nozzle head 2 extends inside or behind the housing 11 formed by the bristles 10 of the brush 8.

Pour permettre le passage d'une position de nettoyage à une autre, la buse 2 et la brosse 8 sont montées à emboîtement axial coulissant, la monture 9 de la brosse 8 entourant la buse 2 sur une partie de sa longueur.To allow the passage from one cleaning position to another, the nozzle 2 and the brush 8 are mounted to sliding axial engagement, the frame 9 of the brush 8 surrounding the nozzle 2 over part of its length.

Dans les exemples représentés, la buse 2 est équipée d'une poignée 12 de saisie qui peut être rapportée ou réalisée d'une seule pièce avec le corps 3 de buse 2, la brosse 8 étant montée à coulissement le long de ladite buse 2.In the examples shown, the nozzle 2 is equipped with a gripping handle 12 which can be attached or made in one piece with the nozzle body 2, the brush 8 being slidably mounted along said nozzle 2.

Dans les exemples représentés, le corps 3 de la buse 2 affecte la forme générale d'un corps de pistolet, la partie 12 dudit corps formant poignée de saisie étant intégrée audit corps. Il doit être noté que ce corps de buse peut également être équipé d'un organe, tel qu'une gâchette, d'obturation du conduit de circulation de fluide entre les orifices 4 et 7 de la buse. Cet organe d'obturation n'a pas été représenté.In the examples shown, the body 3 of the nozzle 2 has the general shape of a gun body, the portion 12 of said grip body being integral with said body. It should be noted that this nozzle body may also be equipped with a member, such as a trigger, for closing the fluid circulation duct between the orifices 4 and 7 of the nozzle. This body shutter has not been shown.

La monture 9 de la brosse 8 est, quant à elle, montée à coulissement axial le long de la partie de la buse formant le canon dudit pistolet.The frame 9 of the brush 8 is, in turn, mounted to slide axially along the portion of the nozzle forming the barrel of said gun.

Dans ce mode de réalisation, la monture 9 de la brosse 8 est, pour un montage à emboîtement coulissant, équipée d'un conduit 13 axial, généralement traversant, disposé dans le prolongement du logement 11 délimité par les poils 10 de la brosse 8. Ce logement 11 délimité par les poils 10 de la brosse 8 est ici réalisé sous forme d'un logement circulaire, les poils 10 de la brosse étant implantés sur la monture 9 de la brosse suivant une disposition parallèle en suivant un tracé formant une ligne circulaire fermée sur ladite monture. Le logement 11 obtenu est donc un logement tubulaire cylindrique.In this embodiment, the mounting 9 of the brush 8 is, for a sliding fitting assembly, equipped with an axial duct 13, generally through, disposed in the extension of the housing 11 delimited by the bristles 10 of the brush 8. This housing 11 delimited by the bristles 10 of the brush 8 is here produced in the form of a circular housing, the bristles 10 of the brush being implanted on the frame 9 of the brush in a parallel arrangement along a path forming a circular line. closed on said mount. The housing 11 obtained is therefore a cylindrical tubular housing.

Il doit être noté qu'une solution équivalente aurait pu consister à équiper la brosse d'une poignée de saisie, la buse étant alors montée à coulissement à l'intérieur de la monture de ladite brosse.It should be noted that an equivalent solution could have been to equip the brush with a gripping handle, the nozzle then being slidably mounted inside the frame of said brush.

Le conduit 13 axial de la monture 9 de la brosse 8 est équipé, côté tête 5 de la buse 2, d'un élargissement formant un logement 14 épaulé de réception de la tête 5 de buse en position escamotée de ladite tête. Dans cette position extrême d'escamotage, épaulement et extrémité proximale de la tête 5 de buse sont en contact d'appui l'un contre l'autre.The axial duct 13 of the frame 9 of the brush 8 is equipped, on the head side 5 of the nozzle 2, with a widening forming a receiving housing 14 for receiving the nozzle head 5 in the retracted position of said head. In this extreme retraction position, shoulder and proximal end of the nozzle head 5 are in abutting contact with each other.

Le logement 14 épaulé du conduit axial de la monture 9 est muni d'une gorge 15 périphérique interne logeant un joint 16 annulaire formant moyen de retenue de la tête 5 de buse dans ledit logement 14. Ce moyen de retenue est bien évidemment un moyen temporaire de retenue, inefficace lorsque l'effort axial exercé sur la brosse est supérieur à cet effort de retenue pour permettre un déplacement relatif entre buse et monture 9. Dans les exemples représentés, le logement 14 épaulé est représenté conique.The housing 14 shoulder of the axial duct of the frame 9 is provided with an internal peripheral groove 15 housing an annular seal 16 forming means for retaining the nozzle head 5 in said housing 14. This retaining means is obviously a temporary means retaining, ineffective when the axial force exerted on the brush is greater than this retaining force to allow a relative displacement between nozzle and mount 9. In the examples shown, the housing 14 shouldered is shown conical.

Le conduit 13 axial de la monture 9 de la brosse est encore équipé, côté corps 3 de buse, d'un élargissement formant un logement 17 épaulé de réception d'un renflement ou élargissement du corps 3 de buse en position saillante de la buse 2. Dans cette position extrême, épaulement et renflement ou élargissement du corps 3 de buse sont en contact d'appui l'un avec l'autre.The axial duct 13 of the frame 9 of the brush is still equipped, body side 3 nozzle nozzle, a widening forming a housing 17 shouldered to receive a bulge or enlargement of the nozzle body 3 in the projecting position of the nozzle 2. In this extreme position, shoulder and enlargement or enlargement of the nozzle body 3 are in supporting contact with each other.

Dans cette position, c'est la force de friction s'exerçant entre corps de buse et logement 17 épaulé de la monture 9 de la brosse 8 qui assure la retenue du corps de buse et de la brosse dans ladite position.In this position, it is the friction force exerted between the nozzle body and housing 17 shouldered of the frame 9 of the brush 8 which ensures the retention of the nozzle body and the brush in said position.

Le dispositif comporte donc dans chacune de ses positions de nettoyage relatives extrêmes des moyens 16, 17 de limitation de déplacement et de retenue de la buse 2 et de la brosse 8.The device therefore comprises, in each of its extreme relative cleaning positions, means 16, 17 for limiting the displacement and retaining the nozzle 2 and the brush 8.

On note que les moyens 16 de retenue de la buse 2 en position escamotée de nettoyage de l'extérieur de l'objet 20 à nettoyer, exercent un effort de retenue supérieur aux moyens 17 de retenue de la buse 2 en position saillante de nettoyage de l'intérieur de l'objet 20 à nettoyer.It should be noted that the means 16 for retaining the nozzle 2 in the retracted position for cleaning the outside of the object 20 to be cleaned, exert a greater retaining force than the means 17 for retaining the nozzle 2 in the projecting cleaning position. inside the object 20 to clean.

En effet, il est nécessaire, lorsque les poils 10 de la brosse font saillie de l'embout 6 de raccordement pour venir en contact direct avec la surface de l'objet 20 à nettoyer, que le déplacement à coulissement de la monture 9 de la brosse le long de la buse soit empêché de manière efficace. C'est pourquoi, dans cette position, les moyens de retenue de la brosse en appui contre la tête de buse sont formés par le joint 16 annulaire tel que décrit ci-dessus.Indeed, it is necessary, when the bristles 10 of the brush protrude from the connection piece 6 to come into direct contact with the surface of the object 20 to be cleaned, that the sliding displacement of the frame 9 of the brush along the nozzle is effectively prevented. Therefore, in this position, the retaining means of the brush resting against the nozzle head are formed by the annular seal 16 as described above.

A l'inverse, lorsque la buse 2 est en position en saillie du logement 11 des poils, la monture 9 de la brosse 8 est retenue dans sa position par simple contact de friction entre parois de la monture et parois correspondantes du corps de buse.Conversely, when the nozzle 2 is in a projecting position of the housing 11 of the bristles, the frame 9 of the brush 8 is retained in its position by simple frictional contact between the walls of the frame and the corresponding walls of the nozzle body.

Dans les exemples représentés, la buse, qui affecte la forme générale d'un pistolet, comporte un corps 3 de buse présentant deux tronçons, l'un élargi délimitant la poignée 12 de saisie du dispositif et portant l'orifice 4 d'entrée de ladite buse raccordable à une source d'alimentation en fluide de nettoyage, l'autre de plus faible section formant une zone rectiligne servant au déplacement axial de ladite monture 9 de brosse 8 le long dudit corps de buse.In the examples shown, the nozzle, which affects the general shape of a gun, comprises a nozzle body 3 having two sections, one enlarged delimiting the grip 12 of the device and carrying the inlet port 4 of the nozzle. said nozzle connectable to a cleaning fluid supply source, the other of smaller section forming a rectilinear zone for axial displacement of said brush mount 8 along said nozzle body.

Ce tronçon de corps de buse de plus faible section se prolonge par la tête 5 de buse équipée d'un embout 6 de raccordement à l'orifice d'entrée du circuit de circulation de fluide de l'objet 20 à nettoyer.This section of nozzle body of smaller section is extended by the nozzle head 5 equipped with a nozzle 6 for connection to the inlet of the fluid circulation circuit of the object 20 to be cleaned.

Le fonctionnement du dispositif 1 de nettoyage, tel que représenté aux figures, est le suivant :

  • dans l'exemple représenté à la figure 4, le dispositif 1 de nettoyage est raccordé en entrée, à une cuve de traitement de fluide de nettoyage. La cuve 23 comporte ainsi une sortie 25 de fluide de nettoyage, neuf ou traité, raccordée à l'orifice 4 d'alimentation en fluide de nettoyage du dispositif 1. La buse 2 est, quant à elle, dans une position dans laquelle elle est prête à être raccordée par son embout 6 de raccordement à l'entrée 24 du pistolet 20 à nettoyer, tandis que le fluide de lavage évacué de la sortie 22 du circuit de circulation de fluide du pistolet 20 à nettoyer est collecté à l'entrée 26 de fluide à traiter de la cuve 23 de traitement de fluide.
Le fluide pourra ainsi circuler en circuit fermé pendant cette opération de nettoyage de l'intérieur de l'objet à nettoyer.The operation of the cleaning device 1, as shown in the figures, is as follows:
  • in the example shown in figure 4 the cleaning device 1 is connected at the inlet to a cleaning fluid treatment tank. The tank 23 thus comprises a new or treated cleaning fluid outlet 25 connected to the cleaning fluid supply port 4 of the device 1. The nozzle 2 is, in turn, in a position in which it is ready to be connected by its connection tip 6 to the inlet 24 of the gun 20 to be cleaned, while the washing fluid discharged from the outlet 22 of the fluid circulation circuit of the gun 20 to be cleaned is collected at the inlet 26 fluid to be treated of the fluid treatment tank 23.
The fluid can circulate in closed circuit during this cleaning operation of the interior of the object to be cleaned.

Lorsque cette phase de nettoyage est achevée, la monture 9 de la brosse 8 est déplacée axialement le long du corps de buse pour permettre à l'extrémité libre des poils 10 de la brosse de s'étendre au-delà de l'orifice 7 d'évacuation de fluide de l'embout 6 de raccordement.When this cleaning phase is completed, the mount 9 of the brush 8 is moved axially along the nozzle body to allow the free end of the bristles 10 of the brush to extend beyond the orifice 7 of the brush. fluid evacuation of the connection piece 6.

Les poils 10 de la brosse peuvent alors venir directement en contact du pistolet 20 à nettoyer, ladite brosse étant alimentée en fluide de nettoyage centralement par l'intermédiaire de la buse. Le fluide de nettoyage est, dans ce cas, collecté à l'entrée 26 de fluide à traiter de la cuve 23 de traitement ou dans un autre récipient de collecte.The bristles 10 of the brush can then come into direct contact with the gun 20 to be cleaned, said brush being supplied with cleaning fluid centrally via the nozzle. In this case, the cleaning fluid is collected at the inlet 26 of fluid to be treated from the treatment tank 23 or in another collection container.

Dans un autre exemple de fonctionnement non représenté, le fluide de nettoyage est neuf et collecté après utilisation dans l'installation de nettoyage pour stockage et traitement ultérieur à l'extérieur de l'installation de nettoyage.In another example of operation not shown, the cleaning fluid is new and collected after use in the cleaning facility for storage and subsequent treatment outside the cleaning installation.

A nouveau, lorsque cette opération de nettoyage de l'extérieur de l'objet est achevée, la monture 9 de la brosse peut être redéplacée à coulissement le long du corps de buse pour laisser la tête de buse faire saillie du logement 11 tubulaire ménagé par les poils 10 de la brosse.Again, when this cleaning operation of the exterior of the object is completed, the mount 9 of the brush may be slidably redeployed along the nozzle body to allow the nozzle head to project from the tubular housing 11 formed by the bristles 10 of the brush.

En conséquence, le passage d'une position de nettoyage à une autre du dispositif s'opère ici par simple déplacement à coulissement de la monture 9 de la brosse 8 le long de la buse.As a result, the passage from one cleaning position to another of the device is effected here by simple sliding movement of the frame 9 of the brush 8 along the nozzle.
