Description

Cette invention concerne une cabine de peinture pour réaliser la peinture de divers matériels, tels que, notamment, des véhicules ou autres.This invention relates to a paint booth for painting various materials, such as, in particular, vehicles or the like.

Le brevet européen n° 79 101 366.7, publié sous le n° 0 006 120, décrit une cabine de peinture comportant un dispositif qui assure un réglage prédéterminé de la vitesse de l'air admis dans l'enceinte de la cabine, qui est pourvue d'au moins une introduction d'air chaud ou froid. Selon ce brevet antérieur, les moyens assurant le contrôle de la vitesse de l'air admis dans l'enceinte sont positionnés dans le circuit de passage de l'air.European patent n ° 79 101 366.7, published under n ° 0 006 120, describes a paint booth comprising a device which provides a predetermined adjustment of the speed of the air admitted into the enclosure of the booth, which is provided at least one introduction of hot or cold air. According to this prior patent, the means ensuring the control of the speed of the air admitted into the enclosure are positioned in the air passage circuit.

Conformément à la présente invention, lesdits moyens positionnés dans le circuit de passage de l'air sont agencés et commandés de façon à garder une vitesse d'air constante,quelle que soit la surface au sol de la pièce à peindre.According to the present invention, said means positioned in the air passage circuit are arranged and controlled so as to keep a constant air speed, whatever the floor area of the part to be painted.

Suivant une forme de réalisation de l'invention, ces moyens consistent en des organes créant une perte de charge dans le circuit de passage de l'air, et sur lesquels on agit pour faire varier le débit d'air admis dans l'enceinte, et/ou le débit de cet air extrait de l'enceinte.According to one embodiment of the invention, these means consist of members creating a pressure drop in the air passage circuit, and on which one acts to vary the flow of air admitted into the enclosure, and / or the flow of this air extracted from the enclosure.

Dans une forme préférée de réalisation de l'invention, ces organes consistent en des volets inclinables, dont les positions sont déterminées en fonction du matériel se trouvant dans la cabine de peinture.In a preferred embodiment of the invention, these members consist of tilting flaps, the positions of which are determined according to the material in the paint booth.

Les divers caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'une de ses formes possibles de réalisation. Il est bien précisé qu'il s'agit uniquement d'un exemple, et que toutes autres formes, proportions et dispositions pourraient être adoptées sans sortir du cadre de l'invention.The various characteristics and advantages of the invention will emerge from the description which follows of one of its possible embodiments. It is clearly stated that this is only an example, and that all other forms, proportions and arrangements could be adopted without departing from the scope of the invention.

Au cours de cette description, on se réfère aux dessins ci-joints, qui montrent :

  • - Figures 1 à 3, des vues schématiques d'une cabine de peinture munie d'un dispositif suivant l'invention, sous différentes densités d'occupation
  • - Figure 4, une vue schématique de la commande des vérins d'actionnement des volets d'obturation.
During this description, reference is made to the attached drawings, which show:
  • - Figures 1 to 3, schematic views of a paint booth fitted with a device according to the invention, under different occupancy densities
  • - Figure 4, a schematic view of the control of the actuating cylinders of the shutters.

De même que dans le brevet antérieur cité plus haut, la cabine se présente sous la forme d'une enceinte close 1, dans laquelle est introduit le matériel à peindre. Le toit de la cabine est muni d'un caisson 2 ouvert sur l'enceinte, et dans lequel est envoyé, par une gaine 2a, de l'air chaud ou froid, par un moyen bien connu en lui-même, tel qu'un ventilateur, et non représenté.As in the earlier patent cited above, the booth is in the form of a closed enclosure 1, into which the material to be painted is introduced. The roof of the cabin is provided with a box 2 open on the enclosure, and into which is sent, by a sheath 2a, hot or cold air, by a means well known in itself, such as a fan, and not shown.

A la sortie de la cabine, l'air vicié introduit dans la canalisation 14 est repris par l'intermédiaire de l'extracteur 10, disposé dans une gaine d'extraction ou cheminée 9.At the exit of the cabin, the stale air introduced into the pipe 14 is taken up via the extractor 10, disposed in an extraction duct or chimney 9.

Conformément à l'invention, des volets 15, 16 sont prévus, respectivement sur la gaine 2a d'amenée d'air à la cabine, et 9 d'extraction de cet air.According to the invention, flaps 15, 16 are provided, respectively on the duct 2a for supplying air to the cabin, and 9 for extracting this air.

Ces volets sont inclinables ; et la modification de leur inclinaiton, en créant une perte de charge plus ou moins importante sur les canalisations dans lesquelles ils sont placés, va permettre de faire varier les débits d'air amenés à l'enceinte (débit de soufflage) et d'extraction de cet air à la sortie de l'enceinte, de façon à conserver une vitesse d'écoulement de l'air dans l'enceinte constante, quelle que soit la surface au sol du matériel à peindre.These shutters are tiltable; and the modification of their inclination, by creating a more or less significant pressure drop on the pipes in which they are placed, will make it possible to vary the air flow rates brought to the enclosure (blowing flow rate) and extraction of this air at the outlet of the enclosure, so as to maintain a constant speed of flow of the air in the enclosure, regardless of the surface area of the material to be painted.

Cette constance dans la vitesse d'écoulement de l'air est particulièrement intéressante.This constancy in the air flow speed is particularly interesting.

En effet, actuellement, les normes de sécurité imposent, pour l'écoulement de l'air, une vitesse de 0,5 m/s, la cabine de peinture étant vide.Indeed, currently, safety standards impose, for air flow, a speed of 0.5 m / s, the paint booth being empty.

Si, dans cette cabine vide, on introduit un matériel de volume important, l'espace laissé libre est parcouru par de l'air sous une vitesse importante, étant donné que les volumes d'air amené à l'enceinte et extrait de cette dernière sont constants.If, in this empty cabin, a material of large volume is introduced, the space left free is traversed by air at a high speed, since the volumes of air brought to the enclosure and extracted from the latter are constant.

Or, cette vitesse d'écoulement considérable est indésirable, car elle est gênante pour l'opérateur et elle compromet l'opération de peinture, du fait que la peinture est entraînée à l'extraction, et le séchage trop rapide, avec les inconvénients que cela entraîne.However, this considerable flow speed is undesirable, because it is inconvenient for the operator and it compromises the painting operation, because the paint is entrained in extraction, and drying too fast, with the disadvantages that this implies.

Ces inconvénients sont évités grâce à l'invention, en prenant comme base de la vitesse de l'air celle fixée par les normes pour la cabine vide, et en agissant sur les débits d'amenée d'air et d'extraction de ce dernier, comme le montrent les Figures 2 et 3, en fonction de la dimension au sol du matériel à traiter, lequel matériel peut être constitué par des éléments dont la grandeur peut aller des pièces détachées au fourgon b de la Figure 3, en passant par un véhicule a de faibles dimensions.These drawbacks are avoided thanks to the invention, by taking as a basis for the air speed that fixed by the standards for the empty cabin, and by acting on the air supply and extraction flow rates of the latter, as shown in Figures 2 and 3, depending on the dimension on the ground of the material to be treated, which material can consist of elements whose size can range from spare parts to the van b of Figure 3, passing by a vehicle with small dimensions.

Si, avec une vitesse v = 0,5 m/s, le débit est Ql, pour une cabine vide ou très peu occupée, pour le véhicule a, il sera : Q2 < QI, et, pour le véhicule b : Q3 < Q2, ces différents débits étant obtenus par une modification de l'inclinaison sur leur axe des volets 15 et 16, entraînant une perte de charge plus ou moins grande dans les canalisations dans lesquelles ils sont disposés.If, with a speed v = 0.5 m / s, the flow rate is Ql, for an empty or very little occupied cabin, for vehicle a, it will be: Q2 <QI, and, for vehicle b: Q3 <Q2 , these different flows being obtained by a modification of the inclination on their axis of the flaps 15 and 16, resulting in a greater or lesser pressure drop in the pipes in which they are arranged.

Les volets sont manoeuvrés et commandés de la façon suivante : Les volets 15 et 16, disposés respectivement sur les canalisations de soufflage et d'extraction, sont commandés chacun par un vérin électrique 17. Chaque volet comporte un secteur 18 qui agit sur l'un des interrupteurs de position 19, qui sont destinés à positionner les volets suivant le type de véhicule à peindre, et qui sont reliés à une armoire de commande 20. L'opérateur dispose, sur l'armoire de commande, de poussoirs 21 en nombre correspondant au type de matériel à peindre. Chacun de ces poussoirs commande, par l'intermédiaire du vérin, la rotation des volets jusqu'à la position déterminée par l'interrupteur de position correspondant.The flaps are operated and controlled in the following manner: The flaps 15 and 16, disposed respectively on the blowing and extraction pipes, are each controlled by an electric actuator 17. Each flap has a sector 18 which acts on one position switches 19, which are intended to position the flaps according to the type of vehicle to be painted, and which are connected to a control cabinet 20. The operator has, on the control cabinet, pushers 21 in corresponding number the type of material to be painted. Each of these pushers controls, by means of the jack, the rotation of the flaps to the position determined by the corresponding position switch.

Chaque fin de course est réglée de façon à avoir une vitesse d'air de 0, 50 m/s.Each limit switch is adjusted so as to have an air speed of 0.50 m / s.

Il faut obligatoirement un interrupteur de position par type de pièce et par type de véhicule.A position switch is required per type of room and per type of vehicle.

Bien entendu, la commande de l'inclinaison des volets pourrait être basée sur la mesure de la vitesse de l'air dans la cabine, au moyen d'un anémomètre. L'information donnée par cet appareil permettrait de faire jouer en parallèle la quantité d'air introduite et la quantité d'air extraite pour que la pression et la vitesse restent constantes.Of course, the control of the inclination of the flaps could be based on the measurement of the air speed in the cabin, using an anemometer. The information given by this device would allow the amount of air introduced and the amount of air extracted to play in parallel so that the pressure and speed remain constant.

Il serait alors possible de moduler en automatique en reliant le traitement de l'information donnée par l'anémomètre à un asservissement aux veines d'air ou aux entraînements, soit diaphragme, soit moto-variateur, etc.It would then be possible to modulate automatically by linking the processing of the information given by the anemometer to a slaving to the air streams or to the drives, either diaphragm, or motor-variator, etc.
