Description

PORTIQUE DE LAVAGE A HAUTE PRESSION DE VEHICULES AUTOMOBILES HIGH PRESSURE WASHING GATE FOR MOTOR VEHICLES
La présente invention se rapporte à un portique de lavage à haute pression de véhicules automobiles.The present invention relates to a portal for high pressure washing of motor vehicles.
Parmi les portiques connus, on en distingue deux catégories principales, l'une utilisant des brosses rotatives et l'autre des rampes de lavage à jets d'eau à haute pression.Among the known gantry cranes, there are two main categories, one using rotary brushes and the other of high pressure water jet washing ramps.
Dans les systèmes à brosses, une brosse horizontale suit le contour du véhicule grâce à la mise en oeuvre de capteurs opto-électroniques (cellules photosensi¬ bles) qui, à chaque trajet de la brosse, détectent le profil du véhicule, ce qui permet de piloter le mouvement de montée/descente de la brosse de manière correspondante, au cours de 1 ' avance du portiq ue.In brush systems, a horizontal brush follows the outline of the vehicle thanks to the use of opto-electronic sensors (photosensitive cells) which, at each brush stroke, detect the profile of the vehicle, which makes it possible to control the up / down movement of the brush in a corresponding manner, during the advance of the gate.
Une telle détection est délicate, voire impossible, lorsqu'on met en oeuvre des jets d'eau à haute pression, le brouillard intense produit par les jets ne permettant pas une commande fiable des cellules.Such detection is delicate, even impossible, when high pressure water jets are used, the intense fog produced by the jets not allowing reliable control of the cells.
Ainsi, dans un premier temps, on a proposé des portiques de lavage à haute pression dont la rampe de lavage horizontale et transversale est fixe en hauteur. Ceci ne permet pas un lavage correct de l'ensemble de la carrosserie, notamment du capot avant et de la partie arrière, trop éloignés de la rampe. De plus, la rampe peut seulement basculer autour d' un axe horizontal transversal, entre deux positions extrêmes de manière à orienter le jet d'un côté ou de l'autre. Le basculement se fait lorsque le portique passe dans la partie centrale du véhicule. Il n'y a de positions intermédiaires d'orientation du jet L'angle d'incidence contre la carrosserie est donc plus ou moins favorable selon le contour du véhicule et la zone d'impactThus, initially, high pressure washing gantries were proposed, the horizontal and transverse washing ramp of which is fixed in height. This does not allow proper washing of the entire body, in particular the front cover and the rear part, which are too far from the ramp. In addition, the ramp can only tilt around a transverse horizontal axis, between two extreme positions so as to orient the jet on one side or the other. Tipping takes place when the gantry passes through the central part of the vehicle. There are no intermediate jet orientation positions.The angle of incidence against the bodywork is therefore more or less favorable depending on the contour of the vehicle and the impact zone
Un tel dispositif a été perfectionné.Such a device has been perfected.
On décrit, par exemple dans le document EP-A-0 507 757, un portique dont la rampe horizontale est mobile en direction verticale afin de suivre fidèlement - ou à peu près fidèlement - le contour du véhicule. Des cellules photo-électriques détectent la forme du véhicule au cours d'un premier déplacement du portique, lors d'une phase de travail qui ne perturbe pas leur détection.We describe, for example in document EP-A-0 507 757, a gantry whose horizontal ramp is movable in the vertical direction in order to follow faithfully - or almost faithfully - the outline of the vehicle. Photoelectric cells detect the shape of the vehicle during a first movement of the gantry, during a work phase which does not disturb their detection.
Les informations des capteurs sont enregistrées et mises en mémoire dans un automate programmable et sont ensuite utilisées lors des trajets subséquents pour le lavage à haute pression.The sensor information is recorded and stored in a programmable controller and is then used on subsequent trips for high pressure washing.
De plus, l'orientation de la rampe est modifiée en continu et par degré au fur et à mesure de l'avance du portique, de telle sorte que l'angle d'incidence du jet soit constamment optimal. Bien entendu, un lavage effectué avec un tel dispositif est bien meilleur car les jets sont proches du véhicule et disposés selon une inclinaison efficace, par rapport à la carrosserie du véhicule.In addition, the orientation of the ramp is changed continuously and by degree as the gantry advances, so that the angle of incidence of the jet is constantly optimal. Of course, washing with such a device is much better because the jets are close to the vehicle and arranged at an effective inclination, relative to the vehicle body.
Il se pose toutefois un problème é au fait que les jets d'eau à haute pression ont une forme généralement conique. Or l'efficacité de lavage est maximale face à l'orifice de sortie de la buse de projection, tandis qu'elle est largement diminuée en péπphéπe du jet (perte de charge). En conséquence, le lavage de la carrosserie n'est pas réalisé uniformément et il est possible qu'il subsiste sur le véhicule nettoyé des zones encore sales. Un objectif de l'invention est de pallier un tel inconvénient, c'est-à-dire de proposer un portique de lavage à haute pression de véhicules qui permette de réaliser un nettoyage efficace et uniforme de la carrosserie.There is however a problem with the fact that the high pressure water jets have a generally conical shape. However, the washing efficiency is maximum opposite the outlet orifice of the spray nozzle, while it is greatly reduced in terms of the jet (pressure drop). Consequently, the washing of the bodywork is not carried out uniformly and it is possible that there remain on the cleaned vehicle areas which are still dirty. An object of the invention is to alleviate such a drawback, that is to say to provide a portal for high pressure washing of vehicles which makes it possible to carry out efficient and uniform cleaning of the bodywork.
Un second objectif est de proposer un portique dont le fonctionnement s'opère sur une courte durée, sans perte de temps inutile. II s'agit d'un portique de concepuon simple et facile à utiliser.A second objective is to offer a gantry crane which operates for a short time, without unnecessary loss of time. It is a simple and easy to use design portal.
Ce portique de lavage à haute pression de véhicules automobiles est mobile longitudinalement le long d'une aire de lavage. Il comprend un montant horizontal transversal et deux montants verticaux parallèles, et est pourvu d'un châssis transversal - appelé châssis principal -, monté entre les montants verticaux, mobile \erticalement et équipé de buses de projection d'eau à haute pression, les buses pouvant pivoter par rapport à un axe horizontal transv ersal. Il est caractérisé en ce que les buses diffusent des jets monodirectionnels d'eau et en ce qu'elles sont portées par une série de rampes disposées transversalement et pourvues de moyens aptes à leur faire subir un mouvement oscillatoire autour d'un axe longitudinal. Ainsi, on va nettoyer efficacement le véhicule en projetant sur sa carrosserie des jets monodirectionnels d'eau sous pression c'est-à-dire dirigés essentielle¬ ment selon l'axe des buses, ces jets étant animés d'un mouvement oscillatoire. Ceci se traduit, en un instant donné, par le nettoyage du véhicule selon une ligne transversale, le déplacement longitudinal du portique permettant de laver l'ensemble de la surface de la carrosserie.This motor vehicle high pressure washing gantry is movable longitudinally along a washing area. It includes a horizontal transverse upright and two parallel vertical uprights, and is provided with a transverse frame - called main frame -, mounted between the vertical uprights, movable \ ertically and equipped with high pressure water spray nozzles, the nozzles can pivot relative to a horizontal transverse axis. It is characterized in that the nozzles diffuse monodirectional water jets and in that they are carried by a series of ramps arranged transversely and provided with means capable of subjecting them to an oscillatory movement about a longitudinal axis. Thus, the vehicle will be effectively cleaned by projecting onto its bodywork one-way jets of pressurized water, that is to say directed essentially along the axis of the nozzles, these jets being driven by an oscillatory movement. This results, in a given instant, in cleaning the vehicle along a transverse line, the longitudinal displacement of the gantry making it possible to wash the entire surface of the body.

Ces montants sont par exemple entraînés en translation au moyen de quatre galets motorisés via deux moto-réducteurs, ceux-ci étant pilotés par un variateur unique équipé de ram pes d' accélération.These amounts are for example driven in translation by means of four rollers motorized via two gearmotors, these are controlled by a single variator equipped with acceleration ram pes.

Between the guide rails 120 of the gantry are provided two guide rails 122 of the wheels of the vehicle to be cleaned. Between these rails is provided a ramp 121 in the shape of a "U" for cleaning the chassis of the vehicle.
A l'entrée de l'aire est prévu un monnayeur 13, tandis que sur le côté de celle-ci sont prévues trois piliers 123 qui reçoivent dans leur partie supérieure les flexibles 124 nécessaires au pilotage du portique.At the entrance to the area is provided a coin mechanism 13, while on the side thereof there are three pillars 123 which receive in their upper part the hoses 124 necessary for piloting the gantry.
Dans l ' ensemble de la présente description, les termes "longitudinal(ement)" et "transversal (ement)" seront employés en référence au déplace¬ ment du portique le long de l'aire de lavage. Ainsi, un élément longitudinal s'étend parallèlement à la direction de déplacement du portique le long de l'aire de lavage. Entre les montants verticaux 11 du portique est prévu un châssis métallique disposé transversalement 2 et qui sera ci-après dénommé châssis principal. Ce châssis affecte en vue de dessus (voir figure 3) la forme d'un rectangle allongé et il s'étend parallèlement au montant horizontal 10 du portique. Il est formé d'un assemblage de deux longerons longitudinaux 21 et de deux longerons transversaux 20. Selon l'axe médian transversal YY' de ce châssis sont prévues deux pièces de fixation 22 disposées à chaque extrémité de ce dernier. Chacune des pièces 22 est fixée à un chariot 23 formé de deux plaques parallèles entre lesquelles sont fixés, fous en rotation, trois galets 230. Leur axe de rotation est parallèle à l'axe YY'. Deux de ces galets sont disposés verticalement à l'aplomb l'un de l'autre tandis que le troisième est décalé latéralement et en hauteur par rapport aux deux autres de sorte que ces trois galets occupent les sommets d'un triangle équilatéral fictif.Throughout this description, the terms "longitudinal (ement)" and "transverse (ement)" will be used with reference to the displacement of the gantry along the washing area. Thus, a longitudinal element extends parallel to the direction of movement of the gantry along the washing area. Between the vertical uprights 11 of the gantry is provided a metal frame arranged transversely 2 and which will hereinafter be called the main frame. This frame assumes in top view (see Figure 3) the shape of an elongated rectangle and it extends parallel to the horizontal upright 10 of the gantry. It is formed by an assembly of two longitudinal beams 21 and two transverse beams 20. According to the transverse median axis YY 'of this chassis are provided two fixing pieces 22 arranged at each end of the latter. Each of the parts 22 is fixed to a carriage 23 formed of two parallel plates between which are fixed, idle in rotation, three rollers 230. Their axis of rotation is parallel to the axis YY '. Two of these rollers are arranged vertically in line with one another while the third is offset laterally and in height with respect to the other two so that these three rollers occupy the vertices of a fictitious equilateral triangle.
Les galets 230 sont adaptés pour coulisser le long d'un colonne verticale 112 solidaire du portique qui s'étend parallèlement à chacun des montants verticaux 11. On expliquera plus loin dans la description comment s'opère le guidage de ces galets. De plus, la face du chariot 23 opposée au châssis 2 comporte une pièce de fixation 24 d'une courroie crantée 240 qui s'étend verticalement. Le châssis 2 est par ailleurs équipé de deux bras parallèles et coudés vers le bas 200, 201, qui s'étendent dans un plan vertical et qui sont disposés longitudinale- ment, à petite distance des profilés d'extrémité 21. Ces bras s'étendent à la fois à l'arrière et à l'avant du châssis 2 et portent chacun une série de cellules photo-électriques 202, dont on expliquera plus loin la fonction.The rollers 230 are adapted to slide along a vertical column 112 integral with the gantry which extends parallel to each of the vertical uprights 11. We will explain later in the description how the guiding of these rollers operates. In addition, the face of the carriage 23 opposite the chassis 2 comprises a fixing part 24 of a toothed belt 240 which extends vertically. The chassis 2 is moreover equipped with two parallel arms bent downwards 200, 201, which extend in a vertical plane and which are arranged longitudinally, at a short distance from the end profiles 21. These arms are extend both to the rear and to the front of the chassis 2 and each carry a series of photocells 202, the function of which will be explained below.
Sur le châssis 2 est articulé un châssis 3 appelé châssis secondaire. Ce châssis, qui affecte également en vue de dessus la forme d'un rectangle allongé, occupe une partie de l'espace délimité par les profilés 20 et 21 du châssis 2.On chassis 2 is articulated a chassis 3 called secondary chassis. This chassis, which also has a top view in the form of an elongated rectangle, occupies part of the space delimited by the profiles 20 and 21 of the chassis 2.
Le châssis 3 est formé de deux profilés transversaux parallèles 30 et deux profilés longitudinaux parallèles 31. Ce châssis est articulé par rapport au châssis principal autour de l'axe YY', au moyen d'équipements adéquats de type connu, fixés sur des traverses 210 qui s'étendent parallèlement au profilé 21 du châssis 2. Un moto- réducteur électrique, monté sur l'un des profilés 21 permet, via un système de poulies et de courroie, d'entraîner en rotation le châssis 2 autour de l'axe YY' pour lui faire occuper une position angulaire particulière.The chassis 3 is formed by two parallel transverse profiles 30 and two parallel longitudinal profiles 31. This chassis is articulated relative to the main chassis around the axis YY ', by means of suitable equipment of known type, fixed on crosspieces 210 which extend parallel to the profile 21 of the chassis 2. An electric geared motor, mounted on one of the profiles 21 allows, via a system of pulleys and belt, to rotate the chassis 2 around the axis YY 'to make it occupy a particular angular position.
Aux figures 2 à 4, le châssis 3 occupe une position intermédiaire, dans le même plan que le châssis 2.In FIGS. 2 to 4, the chassis 3 occupies an intermediate position, in the same plane as the chassis 2.
Comme le montre plus particulièrement la figure 3, le châssis secondaire est équipé d'une série de trois petites tiges parallèles 41 disposés longitudinalement entre les profilés 30. Sur ces tiges 41 sont montées, avec possibilité d'articulation, trois rampes 4 qui s'étendent parallèlement à l'axe YY', c'est-à-dire transversalement par rapport à la direction d'avancement du portique. Dans un autre mode de réalisation, le nombre de rampes pourrait être différentAs shown more particularly in Figure 3, the secondary chassis is equipped with a series of three small parallel rods 41 arranged longitudinally between the profiles 30. On these rods 41 are mounted, with the possibility of articulation, three ramps 4 which extend parallel to the axis YY ′, that is to say transversely with respect to the direction of advance of the gantry. In another embodiment, the number of ramps could be different
Le châssis 3 comporte un moto-réducteur 32 ainsi qu'un système 33 à excentrique et biellettes (non représentés), qui permet d'imprimer à la série des trois rampes 4 un mouvement oscillatoire autour de l'axe XX' matérialisé par les tiges 41.The chassis 3 comprises a geared motor 32 as well as a system 33 with eccentric and rods (not shown), which makes it possible to impart to the series of three ramps 4 an oscillatory movement around the axis XX 'materialized by the rods 41.
Dans une variante de réalisation, chacune des rampes pourrait être équipée de ses propres moyens permettant de la faire osciller.In an alternative embodiment, each of the ramps could be equipped with its own means allowing it to oscillate.
Une position angulaire particulière des rampes 4 est représentée à la figure 2.A particular angular position of the ramps 4 is shown in FIG. 2.
De préférence, le débattement angulaire des rampes par rapport à une position médiane horizontale est inférieur ou égal à 20e.Preferably, the angular movement of the ramps relative to a horizontal median position is less than or equal to 20 e .
Comme le montre également cette figure, chacune des rampes 40 est équipée d'une série de buses 40 aptes à diffuser à travers elles un jet d'eau mono- directionnel, c'est-à-dire ayant un point d'impact de forme circulaire, de très petit diamètre, directement en regard de la sortie de la buse. Bien entendu, les rampes sont équipées de moyens non représentés qui permettent de les alimenter en eau sous haute pression.As this figure also shows, each of the ramps 40 is equipped with a series of nozzles 40 capable of diffusing through them a unidirectional water jet, that is to say having a point of shape impact circular, very small in diameter, directly opposite the outlet of the nozzle. Of course, the ramps are equipped with means not shown which make it possible to supply them with water under high pressure.
Le débattement angulaire des rampes est réglé de telle manière que les jets des buses les plus extérieures de la rampe centrale interfèrent avec la zone d'impact de la buse des deux autres rampes la plus proche du centre du portique.The angular travel of the ramps is adjusted so that the jets of the outermost nozzles of the central ramp interfere with the impact zone of the nozzle of the other two ramps closest to the center of the gantry.
Comme le montre plus particulièrement la figure 8, les deux courroies parallèles 240 qui sont fixées par l'une de leur extrémité aux deux côtés opposés du chariot 2 engrènent chacune avec une paire de roues crantées 111 disposées au niveau de chacun des montants verticaux 11 du portique et mobiles autour d'un axe horizontal et transversal. Pour chaque paire de roues 111, l'une d'entre elles est motrice, par exemple celle située à l'aplomb de l'extrémité de la courroie attachée au châssis 2. La seconde extrémité est fixée à un contrepoids 6 par une pièce de fixation 60.As shown more particularly in FIG. 8, the two parallel belts 240 which are fixed by one of their ends to the two opposite sides of the carriage 2 each mesh with a pair of notched wheels 111 disposed at each of the vertical uprights 11 of the gantry and movable around a horizontal and transverse axis. For each pair of wheels 111, one of them is driving, for example that located directly above the end of the belt attached to the chassis 2. The second end is fixed to a counterweight 6 by a piece of fixing 60.
Ce contrepoids est lui-même solidaire d'une plaque 50 d'un chariot 5, de même type que les chariots 23 précédemment décrits, dont les trois galets 51 coulissent le long de deux colonnes 113 et 114, de même type que la colonne 112.This counterweight is itself integral with a plate 50 of a carriage 5, of the same type as the carriages 23 previously described, the three rollers 51 of which slide along two columns 113 and 114, of the same type as the column 112 .
Un système de roues libres qui équipe les roues motrices 111 évoquées plus haut permet de faire remonter manuellement le châssis 2 le long des colonnes 112 puisque ce châssis est équilibré par le contrepoids 6. Ceci permet d'éviter les problèmes lorsque le châssis arrive pratiquement en contact avec la carrosserie du véhicule à nettoyer.A free wheel system which equips the driving wheels 111 mentioned above makes it possible to manually raise the chassis 2 along the columns 112 since this chassis is balanced by the counterweight 6. This makes it possible to avoid the problems when the chassis arrives practically in contact with the vehicle body to be cleaned.
Bien qu'ils n'aient pas été représentés, le portique de l'invention peut comporter des moyens distributeurs de shampoing ainsi que des rampes d'insufflation d'air chaud. De préférence, ces moyens sont portés par le châssis 2 et/ou par le portique. De plus, les montants verticaux du portique peuvent être équipés de rampes verticales, de même tvpe que les rampes 4 précitées et peuvent être pourvues de moyens adaptés pour leur donner un mouvement oscillant autour d' un axe vertical.Although they have not been shown, the gantry of the invention may include shampoo dispensing means as well as hot air blowing ramps. Preferably, these means are carried by the chassis 2 and / or by the gantry. In addition, the vertical uprights of the gantry can be equipped with vertical ramps, in the same way as the aforementioned ramps 4 and can be provided with means adapted to give them an oscillating movement around a vertical axis.
Nous allons ci-après expliquer le fonctionnement du portique de l'in¬ vention.We will explain below the operation of the portico of the invention.
Comme déjà mentionné, le portique est équipé d'un automate programma- ble qui va gérer l'actionnement des différents équipements du portique.As already mentioned, the gantry is equipped with a programmable automaton that will manage the actuation of the various gantry equipment.
Le véhicule étant en place sur l'aire 12 de lavage et le monnayeur 13 ayant été actionné, le portique est disposé dans la position de la figure 1, c'est-à-dire au niveau de l'avant du véhicule. L'automate avant été activé par le monnayeur 13, celui-ci pilote la descente vers le bas du châssis 2 jusqu'à des butées de fin de course qui équipent les colonnes 112. Ce mouvement est rendu possible par le fait que l'automate actionne la paire de roues crantées décrites plus hautThe vehicle being in place on the washing area 12 and the coin mechanism 13 having been actuated, the gantry is placed in the position of FIG. 1, that is to say at the front of the vehicle. The automaton before being activated by the coin mechanism 13, the latter controls the descent downwards of the chassis 2 to the end of travel stops which equip the columns 112. This movement is made possible by the fact that the automaton operates the pair of notched wheels described above
Durant cette descente la pompe d'alimentation en shampoing est activée. Lorsque le châssis 2 est arrivé en position basse, l'automate pilote la translation du portique dans le sens de la flèche g.During this descent the shampoo supply pump is activated. When the chassis 2 has reached the low position, the automaton controls the translation of the gantry in the direction of the arrow g.
Au moment où la cellule arrière 202 (disposée sur les bras 200) détecte l'avant du véhicule, la montée du châssis est demandée et l'endroit où se trouve le portique mémorisé dans l'automate.When the rear cell 202 (disposed on the arms 200) detects the front of the vehicle, the rise of the chassis is requested and the location of the gantry stored in the automaton.
Ainsi, de manière bien connue, on va progressivement, par avancée du portique et montée ou descente successives du châssis 2 liées à la lecture des cellules photo-électriques 202, détecter la forme du véhicule au cours d'un trajet préliminaire distinct de celui correspondant au lavage à haute pression. Avantageusement ce trajet est celui pendant lequel on arrose le véhicule d'un produit nettoyant tel que du shampoing, opération qui ne perturbe pas la détection du véhicule par les cellules photo-électriques.Thus, in a well known manner, we will gradually, by advancing the gantry and successive ascent or descent of the chassis 2 linked to the reading of the photocells 202, detect the shape of the vehicle during a preliminary journey distinct from that corresponding at high pressure washing. Advantageously, this path is that during which the vehicle is sprayed with a cleaning product such as shampoo, an operation which does not disturb the detection of the vehicle by the photoelectric cells.
Petit-à-petit les informations de ces capteurs sont enregistrées et mises en mémoire dans l'automate programmable et seront utilisées ensuite lors des trajets subséquents pour le lavage à haute pression proprement dit, et le cas échéant pour d'autres opérations telles que l'enduction de la carrosserie pour une substance protectrice ou le séchage.Little by little the information from these sensors is recorded and stored in the programmable controller and will then be used during subsequent journeys for the high pressure washing itself, and if necessary for other operations such as coating of the bodywork for a protective substance or drying.
Lorsque l'opération de détection du profil du véhicule est terminée simultanément à la dépose de shampoing, la translation à grande vitesse du portique 1 dans le sens opposé à la flèche g jusqu'à son point de départ est opérée. Ensuite, du fait des informations transmises à l'automate programmable par les capteurs, le pilotage du portique ne va plus se faire par les cellules mais par l'automate programmable.When the vehicle profile detection operation is completed simultaneously with the removal of shampoo, the high-speed translation of the gantry 1 in the direction opposite to the arrow g to its starting point is effected. Then, due to the information transmitted to the programmable logic controller by the sensors, the control of the gantry will no longer be done by the cells but by the programmable logic controller.
On peut alors procéder au lavage proprement dit de la voiture.We can then proceed to the actual washing of the car.
Pour ce faire, l'alimentation des rampes 4 en eau sous pression est commandée, ainsi que le mouvement oscillatoire de celles-ci autour de l'axe XX'.To do this, the supply of pressurized water to the ramps 4 is controlled, as well as the oscillatory movement of the latter around the axis XX '.
Les jets d'eau J monodirectionnels permettent d'obtenir un lavage efficace de la carrosserie au regard des buses 40. Le mouvement d'oscillation f (figure 5) des rampes 4 permet d'obtenir un lavage selon une ligne transversale, le même jet venant balayer la même surface plusieurs fois de suite. Au cours du déplacement du portique le long de Taire de lavage, l'automate programmable pilote le châssis 3 qui subit un mouvement de basculement autour de l'axe transversal YY' de manière à ce que les jets J diffusés par les buses 40 soient sensiblement perpendiculaires à la carrosserie du véhicule V. C'est ce qui est représenté schématiquement à la figure 9. Lorsqu'on arrive sensiblement au milieu du véhicule, le basculement du châssis 3 est inversé.The monodirectional water jets J make it possible to obtain an effective washing of the bodywork with respect to the nozzles 40. The oscillation movement f (FIG. 5) of the ramps 4 makes it possible to obtain washing along a transverse line, the same jet coming to sweep the same surface several times in a row. During the movement of the gantry along the washing area, the programmable controller controls the chassis 3 which undergoes a rocking movement around the transverse axis YY 'so that the jets J diffused by the nozzles 40 are substantially perpendicular to the vehicle body V. This is shown schematically in Figure 9. When one arrives substantially in the middle of the vehicle, the tilting of the chassis 3 is reversed.
Parallèlement, les rampes latérales qui équipent le portique procèdent au lavage des flancs du véhicule. De préférence, le lavage s'effectue pendant un aller et retour du portique le long du véhicule.At the same time, the side ramps that equip the gantry wash the sides of the vehicle. Preferably, washing takes place during a round trip of the gantry along the vehicle.
Dans la mesure où des opérations de dépôt de cire chaude ou froide et de séchage ont été programmées, celles-ci sont alors effectuées, toujours en tenant compte des informations collectées par l'automate programmable relatives au profil du véhicule.Insofar as hot or cold wax deposition and drying operations have been programmed, these are then carried out, always taking into account the information collected by the programmable controller relating to the profile of the vehicle.
D'autres opérations, telle que le dépôt d'eau adoucie ou osmosée peuvent également être envisagées.Other operations, such as the deposition of softened or reverse osmosis water can also be envisaged.
En fin de cycle, le portique retrouve sa position illustrée à la figure 1.At the end of the cycle, the gantry returns to its position illustrated in Figure 1.

- fréquence d'oscillation des rampes 4 ≈ 90 oscillations (aller/retour) par minute ; " - ramp oscillation frequency 4 ≈ 90 oscillations (round trip) per minute; "
