Description

Unité de soufflage à buse inclinable pour portique de lavage automatique de véhicule. Blowing unit with tilting nozzle for automatic vehicle washing gantry.
La présente invention se rapporte à un ensemble de séchage par air soufflé à au moins deux unités identiques de soufflage pour un véhicule après une séquence de lavage par un portique de lavage automatique.The present invention relates to a blown air drying assembly with at least two identical blowing units for a vehicle after a washing sequence by an automatic washing gantry.
Plus particulièrement, l'ensemble de séchage se rapporte à une unité fonctionnelle formée de deux buses successives dont une est mobile en inclinaison.More particularly, the drying assembly relates to a functional unit formed by two successive nozzles, one of which is movable in inclination.
On a cherché par divers moyens à sécher mécaniquement le plus rapidement et le mieux possible des véhicules après lavage automatique dans les postes de lavage à jets et brosses.Attempts have been made, by various means, to mechanically dry vehicles as quickly and as best as possible after automatic washing in the jet and brush washing stations.
De façon classique, le séchage des véhicules après lavage automatique s'effectue par un flux d'air à température ambiante ou préchauffé soufflé par l'intermédiaire d'au moins une buse fixe ou mobile. L'air projeté sur la carrosserie ne doit pas provenir de trop loin pour éviter la dispersion et la diminution notable de 1'effet mécanique accompagnant. Il ne doit pas non plus être projeté trop près afin d'éviter les dégradations à la peinture ou à son revêtement protecteur et, éventuellement, à la carrosserie du véhicule par des chocs accidentels dus à des défauts de commande du mouvement de la ou des buse(s).Conventionally, the drying of vehicles after automatic washing is carried out by a flow of air at room temperature or preheated blown through at least one fixed or mobile nozzle. The air projected onto the bodywork must not come from too far away to avoid dispersion and the notable reduction of the accompanying mechanical effect. It must also not be projected too close in order to avoid damage to the paint or its protective coating and, possibly, to the vehicle body by accidental impacts due to faults in the control of the movement of the nozzle (s). (s).
On connaît un dispositif de soufflage performant décrit dans le brevet déposé par la société allemande VESUMAT.There is a known efficient blowing device described in the patent filed by the German company VESUMAT.
Les véhicules sont séchés par une buse rectiligne centrale disposée au-dessus de la carrosserie à faible distance. Cette buse est montée mobile en déplacements verticaux. Ces déplacements conjugués aux mouvements de translation du portique le long de la voiture permettent de suivre le profil du l véhicule d'une bouche de soufflage à une distance constante ou quasi constante de la carrosserie.The vehicles are dried by a central rectilinear nozzle placed above the bodywork at close range. This nozzle is mounted movable in vertical movements. These displacements combined with the translational movements of the gantry along the car allow to follow the profile of the l vehicle with a blowing outlet at a constant or almost constant distance from the body.
Les mouvements d'approche ou de retrait de cette buse centrale sont commandés par un ensemble approprié piloté à partir de plusieurs couples émetteur-capteur situés à des hauteurs différentes qui permettent de faire suivre à la buse les formes de la carrosserie pendant le déplacement du portique.The movements of approach or withdrawal of this central nozzle are controlled by an appropriate assembly controlled from several emitter-sensor couples located at different heights which allow the nozzle to follow the shapes of the bodywork during the movement of the gantry .
Cet automatisme permet d'obtenir un séchage uniforme et rapide. Toutefois, il n'est pas sans pré¬ senter quelques inconvénients.This automation allows uniform and rapid drying. However, it is not without presenting some drawbacks.
Tout d'abord, la gestion des différentes détections pour aboutir à une commande unique et les moyens mis en oeuvre en font un système coûteux, nécessitant un entretien fréquent et régulier.First of all, the management of the different detections to achieve a single command and the means used make it an expensive system, requiring frequent and regular maintenance.
Par ailleurs, sa mise en place et ses réglages d'origine apportent une plus-value supplémen¬ taire à 1'ensemble.In addition, its installation and its original settings provide additional added value to the whole.
Finalement, la qualité du séchage ne s'en trouve pas notablement amélioré et les usagers ne remarquent pas, pour la plupart, cette faible diffé¬ rence.Finally, the quality of drying is not significantly improved and the users do not notice, for the most part, this small difference.
La présente invention a pour but de remédier à ces divers inconvénients en proposant une unité de séchage par air soufflé d'une grande simplicité de montage et de fonctionnement apportant un séchage suffisant pour tous les véhicules.The object of the present invention is to remedy these various drawbacks by proposing a blown air drying unit which is very simple to assemble and operate, providing sufficient drying for all vehicles.
A cet effet, elle se rapporte à un ensemble de séchage formé de deux unités identiques de soufflage disposées symétriquement sur chaque montant d'un portique de lavage automatique de part et d'autre d'un véhicule, caractérisé en ce que chaque unité de soufflage se compose d'un fût vertical fixe présentant, dirigée vers le véhicule à sécher, une buse de soufflage fixe, d'un bras mobile supérieur habillé d'une carrosserie se terminant latéralement, en regard du véhicule à sécher, par une buse de soufflage supérieure mobile, le fût fixe et le bras mobile supérieur étant séparés par une articulation protégée par un soufflet.To this end, it relates to a drying assembly formed by two identical blowing units arranged symmetrically on each upright of an automatic washing gantry on either side of a vehicle, characterized in that each blowing unit consists of a fixed vertical barrel having, directed towards the vehicle to be dried, a fixed blowing nozzle, an upper movable arm covered with a body ending laterally, opposite the vehicle to be dried, by a blowing nozzle upper mobile, the fixed shaft and the upper mobile arm being separated by an articulation protected by a bellows.
Les caractéristiques techniques et d'autres avantages de l'invention sont consignés dans la description qui suit, effectuée à titre d'exemple non limitatif sur un mode d'exécution en référence aux dessins accompagnants dans lesquels :The technical characteristics and other advantages of the invention are set out in the description which follows, given by way of nonlimiting example on an embodiment with reference to the accompanying drawings in which:

L'invention se rapporte plus particulièrement à un ensemble de séchage 1 par air soufflé pour un portique 2 de lavage automatique d'un véhicule. L'ensemble de séchage se compose de deux unités de soufflage identiques 3 et 4 disposées symétriquement de part et d'autre de l'emplacement du véhicule défini par l'espace compris entre deux montants latéraux 5 et 6 et d'une structure supérieure transversale 7 équipée de divers organes mécaniques et de raccordement.The invention relates more particularly to a drying assembly 1 by blown air for a gantry 2 for automatic washing of a vehicle. The drying assembly consists of two identical blowing units 3 and 4 arranged symmetrically on either side of the location of the vehicle defined by the space between two lateral uprights 5 and 6 and of a transverse upper structure 7 equipped with various mechanical and connection components.
Le poste représenté à titre d'exemple sur la figure 1 comprend classiquement au moins deux brosses verticales 8 et 9 et une brosse horizontale 10 ainsi que deux dispositifs identiques de lavage des roues 11 et 12.The station shown by way of example in FIG. 1 conventionally comprises at least two vertical brushes 8 and 9 and a horizontal brush 10 as well as two identical devices for washing the wheels 11 and 12.
Bien entendu, un autre type de poste de lavage automatique convient également, en raison de la relative indépendance entre le lavage proprement dit et le séchage dans toute opération de ce type.Of course, another type of automatic washing station is also suitable, because of the relative independence between washing proper and drying in any operation of this type.
En effet, quelle que soit la nature du lavage ou la façon de le pratiquer, le séchage s'avère utile mais non indispensable et sa forme réelle ne dépend nullement du caractère particulier des opérations quiIndeed, whatever the nature of the washing or the manner of practicing it, drying is useful but not essential and its actual form does not depend in any way on the particular nature of the operations which
1'ont précédé.Preceded him.
Les deux unités de soufflage 3 et 4 s'avèrent parfaitement identiques dans leur constitution et dans leur fonctionnement. Ainsi peut-on se contenter de n'en décrire complètement qu'une seule, la deuxième s'en déduisant par simple symétrie.The two blowing units 3 and 4 prove to be perfectly identical in their constitution and in their operation. So we can be content to describe only one completely, the second deduced by simple symmetry.
De façon générale, l'unité de soufflage 3 ou 4 comprend les moyens généraux suivants. Un ensemble vertical de soufflage 13 à extrémité inclinable présente un fût vertical fixe 14 de forme générale cylindrique, une articulation 15 protégée par un soufflet 16 et un bras mobile supérieur 17 entre une position de séchage haute et une position de séchage dite basse proche de la carrosserie du véhicule à sécher. Le bras mobile 17 est habillé d'une carrosserie de forme générale cylindrique 18.In general, the blowing unit 3 or 4 comprises the following general means. A vertical blowing assembly 13 with tilting end has a fixed vertical barrel 14 of generally cylindrical shape, an articulation 15 protected by a bellows 16 and an upper movable arm 17 between a high drying position and a so-called low drying position close to the vehicle body to be dried. The movable arm 17 is covered with a body of generally cylindrical shape 18.
Cette carrosserie délimite un volume intérieur qui débouche sur le côté en regard du véhicule par une bouche linéaire longitudinale ou buse mobile 19, permettant de couvrir à l'état baissé la demi-zone longitudinale médiane de la surface à sécher du véhicule.This body delimits an interior volume which opens on the opposite side of the vehicle by a longitudinal linear mouth or movable nozzle 19, making it possible to cover in the lowered state the median longitudinal half-zone of the surface to be dried of the vehicle.
Le fût vertical fixe 14 présente également en regard du véhicule à sécher une bouche linéaire analogue ou buse fixe 20 sur pratiquement toute la hauteur du fût dont la forme, les dimensions et 1'emplacement permettent de sécher par soufflage toute la surface latérale du véhicule. Ces bouches linéaires de soufflage ou buses peuvent affecter différentes formes techniques particulières permettant d'obtenir des effets identiques ou analogues de séchage d'un véhicule.The fixed vertical barrel 14 also has, opposite the vehicle to be dried, a similar linear mouth or fixed nozzle 20 over practically the entire height of the barrel, the shape, dimensions and location of which allow the entire lateral surface of the vehicle to be blown dry. These linear air outlets or nozzles can affect different specific technical forms allowing effects to be obtained. identical or analogous to drying a vehicle.
L'effet recherché consiste en une conjonction efficace des effets mécaniques de 1'air soufflé et de l'effet thermique de la température ambiante. Selon la présente réalisation, nullement limitative, il s'agit d'ouvertures longitudinales de section rectangulaire flanquée le long de ses bords longitudinaux de deux déflecteurs parallèles 21 et 22, disposés légèrement en biais pour constituer un volume convergent vers l'extérieur permettant d'éjecter une masse d'air sous pression et distribuée en rampe linéaire.The desired effect consists in an effective conjunction of the mechanical effects of the blown air and the thermal effect of the ambient temperature. According to the present embodiment, in no way limiting, they are longitudinal openings of rectangular section flanked along its longitudinal edges by two parallel deflectors 21 and 22, arranged slightly at an angle to form a volume converging towards the outside allowing eject a mass of air under pressure and distributed in a linear ramp.
L'alimentation en air provient d'une source de compression de 1'air se composant par exemple d'un ventilateur 23 animé par un moteur 24 de forte capacité prélevant 1'air ambiant extérieur à partir d' ne prise d'air extérieur par exemple une bouche 25, la forçant dans un conduit aéraulique d'acheminement 26 traversant puis longeant le montant adjacent puis le fût jusqu'aux buses mobile 19 et fixe 20.The air supply comes from an air compression source consisting, for example, of a fan 23 driven by a high capacity motor 24 taking the outside ambient air from an outside air intake by example a mouth 25, forcing it into an aeraulic conveying duct 26 crossing then along the adjacent upright then the barrel to the movable and fixed nozzles 19.
Le circuit aéraulique 26 débouche dans le volume intérieur de l'unité de soufflage par deux ouvertures séparées 27 et 28 établissant deux circuits de distribution séparés, propres à chaque buse. La répartition du flux d'air s'effectue par exemple proportionnellement aux sections des buses.The air circuit 26 opens into the interior volume of the blowing unit by two separate openings 27 and 28 establishing two separate distribution circuits, specific to each nozzle. The air flow is distributed for example in proportion to the sections of the nozzles.
On décrira ci-après la constitution interne de chaque unité de soufflage et plus particulièrement le mécanisme d'actionnement du bras orientable portant la buse supérieure mobile en référence aux figures 4 et 5.The internal constitution of each blowing unit will be described below, and more particularly the actuation mechanism of the orientable arm carrying the movable upper nozzle with reference to FIGS. 4 and 5.
Un support mécanique vertical 29 prenant appui sur une base horizontale 30 maintient deux rou¬ lements ou paliers horizontaux inférieur 31 et supérieur 32 à distance l'un de l'autre dans un même alignement vertical.A vertical mechanical support 29 bearing on a horizontal base 30 keeps two lower bearings or horizontal bearings 31 and upper 32 apart from one another in the same vertical alignment.
Les roulements portent un axe vertical de pivotement 33 supportant le bras mobile 17 terminé en partie supérieure par une pièce d'articulation 34 sur laquelle est monté à pivotement un bras-support 35 à deux branches inférieure 36 et supérieure 37 constituant l'armature de la carrosserie de la buse mobile 19.The bearings have a vertical axis of pivot 33 supporting the mobile arm 17 terminated in the upper part by an articulation piece 34 on which is pivotally mounted a support arm 35 with two lower 36 and upper 37 branches constituting the frame of the body of the mobile nozzle 19.
Ce bras-support 35 pivote dans un plan vertical sous l'effet d'un vérin d'inclinaison 38 articulé d'une part par 1'une de ses extrémités sur la branche inférieure 36 du bras-support 35 et d'autre part, par son autre extrémité, sur un support annexe 39 de forme générale en potence solidaire d'une base fixe.This support arm 35 pivots in a vertical plane under the effect of a tilt cylinder 38 articulated on the one hand by one of its ends on the lower branch 36 of the support arm 35 and on the other hand, by its other end, on an annex support 39 of general shape in a bracket secured to a fixed base.
Le bras-support 35 est rappelé en position haute par un ressort 40 qui relie son extrémité arrière à un point inférieur 41 solidaire de l'axe vertical de pivotement 33.The support arm 35 is returned to the high position by a spring 40 which connects its rear end to a lower point 41 secured to the vertical pivot axis 33.
L'ensemble de ces éléments forment l'ar¬ ticulation 15 entre la buse mobile inclinable 19 et le fût vertical 14. Pour des raisons de protection et de continuité mécanique, chaque articulation 15 est protégée, comme indiqué, par un soufflet en caoutchouc 16.All of these elements form the articulation 15 between the tilting movable nozzle 19 and the vertical barrel 14. For reasons of protection and mechanical continuity, each articulation 15 is protected, as indicated, by a rubber bellows 16 .
La commande en inclinaison du bras-support 35 et ensuite celle de la buse inclinable 19 par rapport au fût s'effectuent par l'intermédiaire du vérin d'in¬ clinaison 38.The tilting control of the support arm 35 and then that of the tilting nozzle 19 relative to the barrel is effected by means of the tilt cylinder 38.
Les essais ont montré qu'il est nécessaire et suffisant de ne prévoir qu'une position haute pour les véhicules du type camionnette et une position basse pour les voitures particulières pour bénéficier d'un séchage correct.Tests have shown that it is necessary and sufficient to provide only a high position for vehicles of the van type and a low position for private cars to benefit from correct drying.
La détermination de 1'inclinaison s'effectue à partir d'un détecteur non représenté dont 1'unique fonction est de déterminer le gabarit général du véhicule, voiture particulière ou utilitaire. Ce détecteur peut être de différents types, occuper différents emplacements et fonctionner à partir de *r-> divers principes. Seule, la fonction générale s'avère importante.The inclination is determined from a sensor (not shown), the sole function of which is to determine the general size of the vehicle, private car or utility vehicle. This detector can be of different types, occupy different locations and operate from * r-> various principles. Only the general function is important.
On citera à titre d'exemple une indexation mécanique ou électronique à partir de la position la plus haute de travail de la brosse supérieure horizon¬ tale.By way of example, mention may be made of mechanical or electronic indexing from the highest working position of the horizontal horizon¬ tal brush.
On peut citer également une détection haute par détecteur lumineux.We can also cite a high detection by light detector.
Comme indiqué, le fût 14 est séparé du bras inclinable ou rabattable par l'articulation 15 permet¬ tant les mouvements.As indicated, the barrel 14 is separated from the tilting or folding arm by the articulation 15 allowing both movements.
Le maintien accidentel en inclinaison basse peut se révéler dangereux dans le cas d'un véhicule dit surélevé. A titre de sécurité, chaque unité de soufflage orientable commande un dispositif d'urgence permettant d'arrêter 1'avance automatique du portique lorsque le corps de la buse mobile touche la carrosserie du véhicule. Ceci permet d'éviter la percussion du bras par les structures hautes de la voiture lors d'un arrêt ou d'un blocage accidentel du bras en position basse ou si la commande en inclinaison basse résulte d'une absence de détection du véhicule. A cet effet, une partie de la buse est pourvue d'au moins un revêtement ou bourrelet 42 en matière amortissante, par exemple en caoucthouc ou en mousse, destiné à amortir un éventuel choc avec la carrosserie et rendre le contact aussi doux que possible pour éviter des marques, rayures ou détérioration de la carrosserie.Accidentally maintaining a low tilt can be dangerous in the case of a so-called raised vehicle. For safety, each adjustable blowing unit controls an emergency device making it possible to stop the automatic advance of the gantry when the body of the movable nozzle touches the body of the vehicle. This makes it possible to avoid percussion of the arm by the high structures of the car during an accidental stopping or blocking of the arm in the low position or if the command in low tilt results from a lack of detection of the vehicle. To this end, part of the nozzle is provided with at least one coating or bead 42 of damping material, for example of rubber or foam, intended to absorb any impact with the body and make the contact as soft as possible for avoid marks, scratches or deterioration of the bodywork.
On a représenté sur les figures 1 et 3 le bourrelet 42 sous la forme d'une bordure périphérique autour de la section de sortie de la buse. Comme représenté sur les figures 3 et 4, le mécanisme d'actionnement du bras-support 35 comporte un détecteur de proximité 43, par exemple magnétique, se composant d'un élément fixe 44, solidaire d'un support 45 lui-même solidaire d'un support fixe, et d'un élément mobile 46 porté par le support annexe 39 en potence solidaire de 1'axe de pivotement 33 du bras sur lequel est articulé le vérin 38 de manoeuvre en inclinaison du bras.FIGS. 1 and 3 show the bead 42 in the form of a peripheral border around the outlet section of the nozzle. As shown in FIGS. 3 and 4, the actuation mechanism of the support arm 35 includes a proximity detector 43, for example magnetic, is component of a fixed element 44, secured to a support 45 itself secured to a fixed support, and to a movable element 46 carried by the auxiliary support 39 in a bracket secured to the pivot axis 33 of the arm on which is articulated the actuator 38 for tilting the arm.
Le détecteur de proximité 43 est monté dans le circuit de commande en déplacement du portique ou dans un circuit supplémentaire pris en compte par la commande du moteur de translation du portique ou agissant sur celle-ci.The proximity detector 43 is mounted in the control circuit for moving the gantry or in an additional circuit taken into account by the control of the translation motor of the gantry or acting on it.
Ainsi, une sollicitation mécanique excep¬ tionnelle de poussée sur le bras provoquera le dépla¬ cement en pivotement de son axe 33 dans les paliers horizontaux qui le portent décalant angulairement l'un de 1'autre les deux éléments 38 et 39 du détecteur de proximité. Cette modification angulaire se traduira par la génération d'une impulsion détectée par un circuit approprié de détection qui agit sur la commande du moteur de translation du portique pour 1'arrêter immédiatement.Thus, an exceptional mechanical stress on the arm will cause the pivoting displacement of its axis 33 in the horizontal bearings which carry it angularly offset the two elements 38 and 39 of the proximity detector . This angular modification will result in the generation of a detected pulse by an appropriate detection circuit which acts on the control of the gantry translation motor to stop it immediately.
On dispose ainsi de deux sécurités princi¬ pales. Tout d'abord, le bras n'oppose aucune résistance car il pivote pour s'effacer. Ensuite, intervient ra- pidement l'arrêt du mouvement de translation du portique.There are thus two main safety features. First of all, the arm offers no resistance because it pivots to disappear. Then, the stop of the gantry translational movement comes quickly.
Il est bien entendu qu'au-delà des moyens décrits, diverses modifications évidentes et variantes simples entrent dans le cadre de la présente invention. It is understood that beyond the means described, various obvious modifications and simple variants fall within the scope of the present invention.
