Description

L'invention concerne généralement une cabine de peinture au pistolet ou par micro-pulvérisation, de véhicules automobiles et autres articles ou objets divers.The invention generally relates to a spray painting or micro-spray painting booth of motor vehicles and other articles or various objects.

Les cabines de peinture de ce type comprennent en général une enceinte fermée, dans laquelle est disposé l'objet à peindre, et qui est associée à un circuit de ventilation produisant une circulation d'air dans l'enceinte, et à des moyens de nettoyage de l'air de ventilation qui sort de l'enceinte chargé d'un brouillard de peinture et qui doit être recyclé ou rejeté à l'atmosphère.Paint booths of this type generally include a closed enclosure, in which the object to be painted is placed, and which is associated with a ventilation circuit producing an air circulation in the enclosure, and with cleaning means. ventilation air which leaves the enclosure charged with a mist of paint and which must be recycled or discharged into the atmosphere.

Ces cabines connues de l'art antérieur comprennent également en général des ventilateurs d'extraction de l'air de la cabine, qui sont en général destinés à assurer un écoulement régulier de l'air de ventilation à travers la cabine pour l'élimination du brouillard formé par la peinture en excès. Il arrive cependant que les filtres d'alimentation de la cabine en air de ventilation se bouchent, de sorte que la cabine est alors mise en dépression par l'action des ventilateurs d'extraction, ce qui représente un inconvénient sérieux venant alors notamment se déposer sur l'objet peint ou à peindre.These cabins known from the prior art also generally comprise fans for extracting air from the cabin, which are generally intended to ensure a regular flow of ventilation air through the cabin for the elimination of fog formed by excess paint. However, it happens that the filters supplying the cabin with ventilation air become blocked, so that the cabin is then placed under vacuum by the action of the exhaust fans, which represents a serious drawback which then comes in particular to deposit on the object painted or to paint.

De plus, le peintre se trouvant à l'intérieur de la cabine est souvent plus ou moins bien protégé du brouillard formé par la peinture en excès en suspension dans l'air.In addition, the painter inside the cabin is often more or less well protected from the fog formed by the excess paint suspended in the air.

L'invention a précisément-pour but d'éviter ces incon- venients de la technique antérieure, et d'améliorer et de régulariser le fonctionnement des cabines de peinture de véhicules automobiles ou d'objets divers tout en permettant de respecter une vitesse minima de circulation d'air à l'intérieur de la cabine imposée par certaines réglementations.The object of the invention is precisely to avoid these drawbacks of the prior art, and to improve and regularize the operation of paint booths for motor vehicles or various objects while allowing a minimum speed of air circulation inside the cabin imposed by certain regulations.

L'invention propose donc une cabine de peinture, pour véhicules automobiles et autres articles ou objets, du type comprenant une enceinte fermée dans laquelle est placé l'objet à peindre, un circuit de ventilation créant une circulation d'air dans ladite enceinte et des moyens de nettoyage de l'air de ventilation sortant de l'enceinte, caractérisée en ce qu'elle comprend des moyens pour aménager, autour de l'objet à peindre, une zone enveloppante d'air ayant un sens prédéterminé de circulation préférentielle, tel que la peinture en excès, projetée au pistolet ou par micro-pulvérisation sur l'objet, se rassemble uniquement dans cette zone et s'écoule avec l'air de ventilation vers les moyens de nettoyage précités et;en ce qu'elle comprend également des moyens pour aspirer l'air circulant dans la cabine sensiblement de haut en bas autour de l'objet à peindre, afin d'établir autour de cet objet des vitesses de circulation d'air supérieures à une valeur minimum prédéterminée.The invention therefore provides a paint booth, for motor vehicles and other articles or objects, of the type comprising a closed enclosure in which the object to be painted is placed, a ventilation circuit creating an air circulation in said enclosure and means for cleaning the ventilation air leaving the enclosure, characterized in that it comprises means for providing, around the object to be painted, an enveloping zone of air having a predetermined direction of preferential circulation, such as that the excess paint, sprayed with a spray gun or by micro-spraying on the object, collects only in this zone and flows with the ventilation air towards the abovementioned cleaning means and; in that it also includes means for sucking the air circulating in the cabin substantially from top to bottom around the object to be painted, in order to establish around this object air circulation speeds greater than a predetermined minimum value.

Selon une autre caractéristique de l'invention, ces moyens d'aspiration comprennent un ventilateur d'aspiration situé à l'extrémité extérieure d'un passage d'extraction d'air reliant l'intérieur de la cabine à l'atmosphère extérieure ou à des moyens de nettoyage ou d'épuration d'air.According to another characteristic of the invention, these suction means comprise a suction fan located at the outer end of an air extraction passage connecting the interior of the cabin to the outside atmosphere or to means for cleaning or purifying air.

Selon encore une autre caractéristique de l'invention, ce passage d'extraction d'air communique avec l'atmosphère extérieure à son extrémité opposée au ventilateur d'aspiration, et communique avec l'intérieur de la cabine par une série d'orifices à section efficace réglable, le ventilateur établissant une forte dépression dans ce passage par aspiration de l'air extérieur, et aspirant par entraînement l'air intérieur de la cabine.According to yet another characteristic of the invention, this air extraction passage communicates with the external atmosphere at its end opposite to the suction fan, and communicates with the interior of the cabin through a series of orifices at adjustable cross-section, the fan establishing a strong vacuum in this passage by suction of the outside air, and drawing in the air inside the cabin by driving.

Ainsi, cette zone enveloppante d'air selon l'invention, qui est formée autour du véhicule ou de l'objet à peindre, permet de rassembler toute la peinture en excès en suspension dans l'air et de la diriger vers les moyens de nettoyage d'air prévus à la sortie de l'enceinte à des vitesses de circulation relativement importantes sans augmenter le débit de soufflage dans la cabine.Thus, this air-enveloping zone according to the invention, which is formed around the vehicle or the object to be painted, makes it possible to collect all the excess paint suspended in the air and to direct it towards the cleaning means. air provided at the outlet of the enclosure at relatively high circulation speeds without increasing the blowing rate in the cabin.

Selon une autre caractéristique de l'invention, les moyens précités d'aménagement de la zone enveloppante d'air comprennent un caisson de soufflage et de détente d'air pulsé, alimenté en air extérieur et débouchant dans ladite enceinte au-dessus de l'objet à peindre, pour alimenter cette enceinte par un écoulement laminaire d'air, et une fosse de sortie d'air, située sous l'objet à peindre et reliée à un caisson ou à un bac de nettoyage d'air, ce qui permet de parfaitement protéger le peintre.According to another characteristic of the invention, the aforementioned means for arranging the air enveloping zone comprise a blowing and expansion box for forced air, supplied with outside air and opening into said enclosure above the object to be painted, to feed this enclosure by a laminar flow of air, and an air outlet pit, located under the object to be painted and connected to a box or to an air cleaning tank, which allows to protect the painter perfectly.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant divers modes de réalisation de l'invention et dans lesquels :

  • La figure 1 est une vue schématique en coupe transversale d'une cabine de peinture selon l'invention; la figure 2 est une vue schématique en coupe longitudinale de la cabine représentée en figure 1; la figure 3 est une vue en coupe avec arrachement partiel selon la ligne III-III de la figure 2; la figure 4 représente schématiquement une coupe transversale d'une variante de réalisation d'une cabine selon l'invention; la figure 5 représente schématiquement une coupe transversale d'une autre variante de réalisation d'une cabine selon l'invention; et la figure 6 est une vue schématique en coupe longitudinale de la cabine représentée sur la figure 5.
The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating various embodiments of the invention and in which:
  • Figure 1 is a schematic cross-sectional view of a paint booth according to the invention; Figure 2 is a schematic view in longitudinal section of the cabin shown in Figure 1; Figure 3 is a sectional view with partial cutaway along line III-III of Figure 2; Figure 4 schematically shows a cross section of an alternative embodiment of a cabin according to the invention; Figure 5 schematically shows a cross section of another alternative embodiment of a cabin according to the invention; and FIG. 6 is a schematic view in longitudinal section of the cabin shown in FIG. 5.

Dans les figures 1, 2 et 3, on a représenté schématiquement un premier mode de réalisation d'une cabine de peinture selon l'invention.In Figures 1, 2 and 3, there is shown schematically a first embodiment of a paint booth according to the invention.

Chaque cabine de peinture comprénd essentiellement une enceinte fermée 50 dans laquelle est placé l'objet à peindre, ici, une carrosserie 51 de véhicule automobile par exemple, et qui est associée à un système d'alimentation 52 qui comprend, comme on le voit en figure 1, un bâti 14 comprenant des moyens de génération'd'air pulsé, tels par exemple qu'un compresseur, une soufflante, ou analogue, qui sont alimentés en air extérieur par l'intermédiaire d'un caisson de filtrage 15 et qui envoient l'air pulsé sous pression dans un conduit coudé 16 permettant une pré-détente de l'air. La sortie du conduit coudé 16 est reliée à l'entrée d'un autre conduit 17 formant un passage divergent, à l'intérieur duquel sont disposées des cloisons ou des volets de guidage et de répartition d'air, et qui alimentent un caisson 19 filtrant de soufflage et de détente d'air, qui repose et est fixé par sa face horizontale inférieure sur la paroi supérieure horizontale 20 de la cabine 50. Au niveau du caisson 19 cette paroi 20 est naturellement percée d'une multitude de trous, pour assurer le passage de l'air depuis le caisson 19 à l'intérieur de la cabine 50, comme indiqué par les flèches dans les figures 1 et 2.Each paint booth essentially comprises a closed enclosure 50 in which the object to be painted is placed, here, a bodywork 51 of a motor vehicle for example, and which is associated with a supply system 52 which comprises, as seen in 1, a frame 14 comprising generating means' pulsating air, such as for example a compressor, a blower, or the like, which are supplied with outside air via a filter box 15 and which send the pulsed air under pressure into a bent duct 16 allowing pre-expansion of the air. The outlet of the bent duct 16 is connected to the inlet of another duct 17 forming a divergent passage, inside which are disposed partitions or flaps for guiding and distributing air, and which supply a box 19 blowing and air expansion filter, which rests and is fixed by its lower horizontal face on the horizontal upper wall 20 of the cabin 50. At the level of the box 19 this wall 20 is naturally pierced with a multitude of holes, for ensure the passage of air from the box 19 inside the cabin 50, as indicated by the arrows in Figures 1 and 2.

On remarquera que le caisson 19.a une forme générale en biseau, s'amincissant, et que sa section transversale diminue progressivement depuis l'extrémité du caisson reliée au passage divergent 17 jusqu'à l'extrémité opposée. Ainsi, l'air sortant du passage divergent 17 et pénétrant dans le caisson 19 est réparti de façon uniforme sur l'ensemble de la surface filtrante de ce caisson, sans vibration et sans effet de trémie qui auraient l'inconvénient de saupoudrer de poussière la carrosserie 51 du véhicule se trouvant directement sous la sortie du caisson 19, comme on peut le voir dans les figures 1 et 2. Par ailleurs, le passage divergent 17 transforme l'écoulement tourbillonnaire produit par un compresseur, une soufflante ou analogue, en écoulement laminaire.It will be noted that the box 19 has a general bevel shape, thinner, and that its cross section gradually decreases from the end of the box connected to the divergent passage 17 to the opposite end. Thus, the air leaving the diverging passage 17 and entering the box 19 is distributed uniformly over the entire filtering surface of this box, without vibration and without hopper effect which would have the disadvantage of dusting the dust body 51 of the vehicle located directly under the outlet of the box 19, as can be seen in FIGS. 1 and 2. Furthermore, the divergent passage 17 transforms the swirl flow produced by a compressor, a blower or the like, into flow laminar.

L'objet à peindre 51 repose sur un faux plancher 53 formera l'intérieur de la cabine, à une faible hauteur au-dessus du sol, et définissant un passage central longitudinal 54 s'étendant d'un bout à l'autre de la cabine comme représenté dans les figures 2 et 3. La paroi supérieure horizontale de ce passage 54 comprend des séries d'orifices 55 permettant de faire communiquer l'intérieur de ce passage 54 avec l'intérieur de la cabine 50. Ces orifices 55 constituent par exemple deux rangées parallèles s'étendant longitudinalement à l'intérieur de la cabine. On remarquera que l'objet à peindre 51 est disposé juste au-dessus du passage 54, et que les orifices 55 se trouvent sous l'objet 51, le passage 54 pouvant avoir selon les cas, soit une largeur supérieure à celle de l'objet, soit une largeur inférieure.The object to be painted 51 rests on a raised floor 53 will form the interior of the cabin, at a low height above the ground, and defining a longitudinal central passage 54 extending from one end to the other of the cabin as shown in Figures 2 and 3. The horizontal upper wall of this passage 54 comprises series of orifices 55 making it possible to communicate the interior of this passage 54 with the interior of the cabin 50. These orifices 55 constitute, for example, two parallel rows extending longitudinally to the cabin interior. It will be noted that the object to be painted 51 is placed just above the passage 54, and that the orifices 55 are located under the object 51, the passage 54 possibly having, as the case may be, a width greater than that of the object, or a smaller width.

Ce passage 54 est équipé de volets de régulation et de répartition 56, qui sont réglables de façon à permettre une répartition uniforme de l'air de ventilation autour de la carrosserie 51 et d'obtenir ainsi une ventilation équilibrée et égale sur l'ensemble de la carrosserie. Les inclinaisons de ces volets sont réglées par mesure à l'anénomètre en fonction des normes, du volume à traiter; et des débits imposés par la législation. Par une extrémité, le passage 54 débouche à l'extérieur de la cabine 50, dans un caisson d'extraction d'air 57 équipé d'un ventilateur d'aspiration 58, et qui peut former cheminée de rejet à l'atmosphère, ou bien être associé à des moyens de nettoyage et d'épuration d'air, comme cela est décrit dans ce qui suit.This passage 54 is equipped with regulation and distribution flaps 56, which are adjustable so as to allow a uniform distribution of the ventilation air around the bodywork 51 and thus to obtain a balanced and equal ventilation over all of the body. The inclinations of these flaps are adjusted by measurement at the anenometer according to standards, the volume to be treated; and debits imposed by law. At one end, the passage 54 opens outside the cabin 50, into an air extraction box 57 fitted with a suction fan 58, and which can form a chimney for rejecting the atmosphere, or well be associated with air cleaning and cleaning means, as described in the following.

A son extrémité opposée, le passage 54 se termine par une rampe inclinée 60 permettant d'amener l'objet à peindre, quand il s'agit d'un véhicule automobile, à l'endroit voulu dans la cabine au-dessus du passage 54. On notera que, comme la hauteur du faux plancher 53 au-dessus du sol de la cabine 50 est relativement très faible, la longueur de cette rampe inclinée 60 est faible, et sa pente est également faible.At its opposite end, the passage 54 ends in an inclined ramp 60 making it possible to bring the object to be painted, when it is a motor vehicle, to the desired location in the cabin above the passage 54 It will be noted that, since the height of the raised floor 53 above the floor of the cabin 50 is relatively very small, the length of this inclined ramp 60 is small, and its slope is also small.

Au voisinage de cette rampe inclinée; le passage 54 communique également avec l'atmosphère extérieure par exemple par deux conduits transversaux 61, formés sous le faux plancher 53. Ces conduits 61 permettent un débit d'air relativement important.In the vicinity of this inclined ramp; the passage 54 also communicates with the external atmosphere for example by two transverse conduits 61, formed under the raised floor 53. These conduits 61 allow a relatively large air flow.

Cette cabine de peinture est utilisée de la façon suivante.This paint booth is used in the following manner.

L'objet à peindre 51 est amené, en roulant sur la rampe inclinée 60, à l'intérieur de la cabine 50 dans la position représentée en figure 2. Le générateur 52 d'air, éventuellement d'air chaud, est mis en route, et l'air est introduit à l'intérieur de la cabine de la façon représentée par les flèches. La cabine 50 étant fermée, le passage 54 constitue pour l'air amené dans la cabine la seule voie de sortie. En raison de la forme particulière en biseau du caisson 19, la répartition d'air est uniforme et laminaire sur toute la surface filtrante du caisson 19 et pénètre donc dans la cabine sans turbulence. Cet air forme autour de la carrosserie 51 une zone enveloppante d'air 62, qui comprend un matelas d'air extérieur représenté en pointillés, et ayant une épaisseur relativement constante et limitée, et un coussin d'air 63 formé par un film mince d'air directement sur la carrosserie 51.The object to be painted 51 is brought, while rolling on the inclined ramp 60, inside the cabin 50 in the position shown in FIG. 2. The generator 52 of air, possibly hot air, is started up , and air is introduced inside the cabin as shown by the arrows. The cabin 50 being closed, the passage 54 constitutes for the air brought into the cabin the only exit way. Due to the particular bevel shape of the box 19, the air distribution is uniform and laminar over the entire filtering surface of the box 19 and therefore enters the cabin without turbulence. This air forms around the bodywork 51 an air enveloping zone 62, which comprises an outside air mattress shown in dotted lines, and having a relatively constant and limited thickness, and an air cushion 63 formed by a thin film d air directly on the bodywork 51.

De la sorte, les poussières et brouillards résiduels se trouvant dans la cabine ne peuvent adhérer sur la carrosserie 51.In this way, the residual dust and mist found in the cabin cannot adhere to the bodywork 51.

Le ventilateur d'extraction 58 est mis en marche en même temps que le générateur 52, ou bien un peu avant le début de la peinture, et il produit dans le passage 54 une forte dépression provoquant une aspiration d'air extérieur importante par les conduits 61, et donc un débit d'air important dans le passage 54, dans le sens indiqué par les flèches en pointillé en figure 3. Ce débit important dans le passage 54 provoque, par les orifices 55,-une aspiration de l'air se trouvant à l'intérieur de la cabine, cette aspiration se faisant par entraînement (principe de la trompe à eau). Les volets de régulation et de répartition 56 sont réglés individuellement de telle sorte que le débit de l'air passant par les orifices 55 est constant et uniforme d'un bout à l'autre du passage 54, bien que le ventilateur d'extraction 58 se trouve relié à une extrémité de ce passage. On notera que les séries d'orifices 55 peuvent être constituées par des grilles, des caillebotis, etc...The exhaust fan 58 is started at the same time as the generator 52, or a little before the start of painting, and it produces in the passage 54 a strong vacuum causing suction significant outside air flow through the conduits 61, and therefore a significant flow of air in the passage 54, in the direction indicated by the dotted arrows in FIG. 3. This significant flow in the passage 54 causes, through the orifices 55, -an aspiration of the air located inside the cabin, this aspiration being done by entrainment (principle of the water pump). The regulation and distribution flaps 56 are individually adjusted so that the air flow rate passing through the orifices 55 is constant and uniform from one end of the passage 54 to the other, although the exhaust fan 58 is connected to one end of this passage. It should be noted that the series of orifices 55 can be constituted by grids, gratings, etc.

Cette aspiration d'air au travers des orifices 55 se traduit par une augmentation importante de la vitesse de circulation d'air dans la cabine 50 autour de l'objet à peindre 51, sans qu'il soit nécessaire d'augmenter le débit d'air fourni par le générateur 52.This suction of air through the orifices 55 results in a significant increase in the speed of air circulation in the cabin 50 around the object to be painted 51, without it being necessary to increase the flow of air supplied by the generator 52.

A titre d'exemple, on indiquera que l'on obtient ainsi facilement des vitesses d'air supérieures ou égales à 0,5 mètre par seconde dans la cabine, de sorte que le peintre ou l'ouvrier se trouvant dans cette cabine est parfaitement protégé contre les brouillards de peinture en suspension dans l'air. A titre d'exemple, on indiquera également qu'il suffit d'utiliser, dans une cabine selon l'invention, un générateur de chaleur de 80 à 150.000 calories par heure, alors qu'il faudrait disposer d'un générateur de 250.000 calories par heure pour obtenir le même résultat, si le ventilateur d'extraction 58 n'était pas prévu. Il en résulte bien évidemment un gain important sur le prix d'achat de ce générateur, et une économie de fonctionnement également très importante.By way of example, it will be indicated that it is thus easy to obtain air speeds greater than or equal to 0.5 meters per second in the cabin, so that the painter or the worker in this cabin is perfectly protected against spraying of airborne paint. By way of example, it will also be indicated that it suffices to use, in a cabin according to the invention, a heat generator of 80 to 150,000 calories per hour, whereas it would be necessary to have a generator of 250,000 calories per hour to obtain the same result, if the exhaust fan 58 was not provided. This obviously results in a significant gain on the purchase price of this generator, and an economy of function also very important.

On remarquera que, bien qu'un ventilateur d'extraction 58'soit relié au passage 54, l'air se trouvant dans la cabine est cependant toujours en légère surpression par rapport à la pression atmosphérique extérieure.It will be noted that, although an exhaust fan 58 'is connected to the passage 54, the air in the cabin is however still under slight overpressure relative to the external atmospheric pressure.

En figure 4, on a représenté une variante de réalisation de la cabine selon l'invention.In Figure 4, there is shown an alternative embodiment of the cabin according to the invention.

Cette cabine 65 diffère de celle représentée dans les figures 1 à 3, en ce que le faux plancher 53 est remplacé par un caisson creux 66 formant un passage longitudinal 67 s'étendant sur sensiblement toute la longueur de la cabine 65. Le caisson 66 a à peu près la même hauteur que le faux plancher 53, et une largeur supérieure à celle du passage 54, mais inférieure à celle de la cabine 65. Le véhicule dont la carrosserie est à repeindre peut donc être placé sur la face supérieure du caisson creux 66. Cette face supérieure comprend, comme le passage 54, des séries d'orifices 68 et est équipée de volets de répartition et de régulation 69.This cabin 65 differs from that shown in Figures 1 to 3, in that the raised floor 53 is replaced by a hollow box 66 forming a longitudinal passage 67 extending over substantially the entire length of the cabin 65. The box 66 has roughly the same height as the raised floor 53, and a width greater than that of the passage 54, but less than that of the cabin 65. The vehicle whose bodywork is to be repainted can therefore be placed on the upper face of the hollow box 66. This upper face comprises, like the passage 54, series of orifices 68 and is equipped with distribution and regulation flaps 69.

On comprend que dans ce cas le peintre ou l'ouvrier se tient debout à c8té du caisson 66, lorsqu'il travaille sur la carrosserie à peindre.It is understood that in this case the painter or the worker is standing next to the box 66, when working on the body to be painted.

On a représenté encore une autre variante de l'invention dans les figures 5 et 6. Dans ce cas, le véhicule dont la carrosserie est à repeindre repose directement sur le sol de la cabine 70, et le passage 54 du premier mode de réalisation ou le caisson creux 66 du second mode de réalisation est remplacé par deux caissons creux latéraux 71, qui s'étendent longitudinalement et parallèlement l'un à l'autre d'un bout à l'autre de la cabine 70, et qui sont écartés entre eux de façon à former un espace libre 73 dans lequel le véhicule peut être disposé. Le côté vértical longitudinal des deux caissons 71 définissant l'espace libre 73 forme une série d'orifices 74, analogues aux orifices 55 du premier mode de réalisation ou aux orifices 68 du second mode de réalisation. Chaque caisson creux 71 est encore équipé de volets de régulation et de répartition 75 jouant le même rôle que les volets 56 ou 69 précités.Yet another variant of the invention is shown in Figures 5 and 6. In this case, the vehicle whose body is to be repainted rests directly on the floor of the cabin 70, and the passage 54 of the first embodiment or the hollow box 66 of the second embodiment is replaced by two lateral hollow boxes 71, which extend longitudinally ment and parallel to one another from one end to the other of the cabin 70, and which are spaced apart so as to form a free space 73 in which the vehicle can be arranged. The longitudinal vertical side of the two boxes 71 defining the free space 73 forms a series of orifices 74, similar to the orifices 55 of the first embodiment or to the orifices 68 of the second embodiment. Each hollow box 71 is also equipped with regulation and distribution flaps 75 playing the same role as the aforementioned flaps 56 or 69.

Ces deux caissons 71 débouchent à l'extérieur à une de leurs extrémités, dans un caisson d'extraction 57 pourvu d'un ventilateur d'aspiration 58. A leurs extrémités opposées, les deux caissons 71 débouchent également à l'extérieur, par un orifice 76, comme in- diqué en figure 6. These two boxes 71 open to the outside at one of their ends, in an extraction box 57 provided with a suction fan 58. At their opposite ends, the two boxes 71 also open to the outside, by a orifice 76 as in- d ic in FIG 6.

Ce troisième mode de réalisation présente l'avantage que le véhicule à repeindre repose directement sur le sol de la cabine, ce qui permet de diminuer la hauteur de la cabine, de ne pas avoir de rampe d'accès et d'installer des cabines de peinture en des endroits où la hauteur est limitée.This third embodiment has the advantage that the vehicle to be repainted rests directly on the floor of the cabin, which makes it possible to reduce the height of the cabin, to have no access ramp and to install painting in places where height is limited.

On comprend bien entendu que le passage d'extraction d'air, qui a été représenté dans les figures 1 à 6 comme formé au-dessus du sol de la cabine, peut être formé également par une fosse creusée dans le sol de la cabine, lorsqu'on le souhaite.It is understood of course that the air extraction passage, which has been shown in FIGS. 1 to 6 as formed above the floor of the cabin, can also be formed by a pit dug in the floor of the cabin, when desired.

L'air ainsi extrait de la cabine, au moyen du caisson 57 et du ventilateur 58, peut être soit rejeté directement à l'atmosphère, soit épuré et nettoyé avant d'être rejeté à. l'atmosphère.The air thus extracted from the cabin, by means of the box 57 and the fan 58, can either be discharged directly into the atmosphere, or purified and cleaned before being discharged. the atmosphere.

Pour cela, l'invention prévoit de faire passer l'air extrait dans la cabine de peinture dans un circuit comprenant en série : une fosse ou un canal rempli d'eau ou de liquide approprié, des buses de pulvérisation, des filtres à choc.For this, the invention provides to pass the air extracted in the paint booth in a circuit comprising in series: a pit or a channel filled with water or suitable liquid, spray nozzles, impact filters.

Un tel circuit de nettoyage peut également servir pour une aire de ponçage, de lustrage, etc.., et comprend une fosse du type précité, munie de volets de régulation, et associée à des moyens d'aspiration : ainsi l'air chargé de poussière est aspiré uniformément sur toute la longueur de la fosse, quel que soit l'emplacement des moyens d'aspiration.Such a cleaning circuit can also be used for a sanding, buffing, etc. area, and includes a pit of the aforementioned type, provided with regulating flaps, and associated with suction means: thus the air charged with dust is sucked evenly along the entire length of the pit, regardless of the location of the suction means.

Selon une variante, ce circuit de nettoyage peut comprendre par exemple des séries de couches superposées de charbon actif, une cuve ou une fosse remplie d'un liquide gras approprié, à fort pouvoir de rétention, des buses de pulvérisation de ce liquide, des filtres à choc, et éventuellement encore d'autres couches superposées de charbon actif.According to a variant, this cleaning circuit can comprise, for example, series of superimposed layers of activated carbon, a tank or a pit filled with an appropriate fatty liquid, with high retention power, spray nozzles for this liquid, filters impact, and possibly other superimposed layers of activated carbon.

Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et représentés qui n'ont été donnés qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cas des revendications qui suivent.Of course, the invention is in no way limited to the embodiments described and shown which have been given only by way of example. In particular, it includes all the means constituting technical equivalents of the means described, as well as their combinations if these are carried out according to the spirit and implemented in the case of the claims which follow.
