Description

"Dispositif d'application d'un produit liquide". "Device for applying a liquid product".
L'invention concerne un dispositif d'appli¬ cation d'un produit liquide, en particulier de la peinture, comprenant un applicateur pourvu d'au moins un rouleau agencé pour appliquer le produit sur une surface et une unité d'alimentation pourvue d'une pompe et d'une conduite au moins en partie flexible reliant la pompe à 1 'applicateur, ladite pompe étant reliée à une unité de commande agencée pour régler le débit du liquide à fournir.The invention relates to a device for applying a liquid product, in particular paint, comprising an applicator provided with at least one roller arranged to apply the product to a surface and a supply unit provided with a pump and an at least partly flexible pipe connecting the pump to the applicator, said pump being connected to a control unit arranged to regulate the flow rate of the liquid to be supplied.
Un tel dispositif est connu du brevet US 4.424.011. Suivant le dispositif connu, de la peinture est amenée à partir d'un réservoir et via la conduite vers le rouleau afin de l'appliquer sur la surface. La pompe utilisée pour amener le liquide vers le rouleau est une pompe péristaltique dont le débit est réglable grâce à l'unité de commande. Avant d'utiliser le dispo¬ sitif, l'utilisateur ajuste le débit voulu en actionnant l'unité de commande, formée par un bouton de réglage. La pompe fonctionnera alors pour fournir le débit de peinture prédéterminé.Such a device is known from US patent 4,424,011. According to the known device, paint is brought from a reservoir and via the line to the roller in order to apply it to the surface. The pump used to bring the liquid to the roller is a peristaltic pump, the flow rate of which can be adjusted using the control unit. Before using the device, the user adjusts the desired flow rate by actuating the control unit, formed by an adjustment button. The pump will then operate to provide the predetermined paint flow.
Un inconvénient du dispositif connu est que le débit de produit liquide est pratiquement constant et ne tient pas compte de la vitesse à laquelle le rouleau circule sur la surface. La seule façon de modifier ce débit est de tourner un bouton de réglage qui se trouve sur le dispositif, ce qui est peu commode car cela nécessite le déplacement vers l'unité de commande et le cas échéant l'interruption des travaux de peinture. Le fait de ne pas tenir compte de la vitesse du rouleau entraîne que la couche de peinture appliquée sera soit insuffisante lors d'un mouvement trop rapide, soit sursaturée lors d'un mouvement trop lent. L'utilisateur doit donc fréquemment actionner le bouton marche/arrêt de la pompe ou suivre le rythme imposé par le débit prédéterminé. De plus lors d'un arrêt du travail ou d'un rythme inadapté un risque de débordement de l'applica¬ teur n'est pas à exclure.A drawback of the known device is that the flow rate of liquid product is practically constant and does not take into account the speed at which the roller circulates on the surface. The only way to modify this flow rate is to turn an adjustment knob located on the device, which is inconvenient because it requires moving to the control unit and, if necessary, interrupting the painting work. Ignoring the roller speed causes the layer of paint applied to be either insufficient during too rapid movement, or oversaturated during too slow movement. The user must therefore frequently press the pump on / off button or follow the rhythm imposed by the predetermined flow. In addition, during a work stoppage or at an unsuitable pace, the risk of the applicator overflowing cannot be excluded.
L'invention a pour but de remédier à ces inconvénients.The invention aims to remedy these drawbacks.
A cette fin un dispositif suivant l'inven¬ tion est caractérisé en ce que le dispositif comporte un détecteur de vitesse du mouvement du rouleau sur la surface, ledit détecteur étant agencé pour fournir un signal de contrôle correspondant à ladite vitesse, ledit détecteur étant relié à l'unité de commande agencée pour régler le débit de produit liquide fourni par la pompe sous contrôle dudit signal de contrôle.To this end, a device according to the invention is characterized in that the device comprises a detector for the speed of movement of the roller on the surface, said detector being arranged to supply a control signal corresponding to said speed, said detector being connected to the control unit arranged to adjust the flow rate of liquid product supplied by the pump under control of said control signal.
En déterminant la vitesse de mouvement du rouleau à l'aide du détecteur, cette vitesse peut être prise en considération pour déterminer le débit de liquide que la pompe doit fournir. L'unité de commande déterminera alors ce débit en fonction du signal de contrôle correspondant à la vitesse et ajustera le débit de la pompe suivant cette vitesse. L'utilisateur ne doit donc plus se soucier de la vitesse à laquelle il fait avancer le rouleau pour obtenir une couche de peinture dont l'épaisseur est sensiblement constante sur tout le trajet, puisque le dispositif ajuste le débit en fonc- tion de cette vitesse. Il ne doit plus interrompre son travail car il ne doit plus ajuster lui-même le débit en fonction de la vitesse du mouvement du rouleau. C'est donc le dispositif même qui suit le rythme de l'utilisa¬ teur. II faut noter que la demande de brevet GB-A-By determining the speed of movement of the roller using the detector, this speed can be taken into account to determine the flow of liquid that the pump must supply. The control unit will then determine this flow rate according to the control signal corresponding to the speed and adjust the pump flow rate according to this speed. The user therefore no longer has to worry about the speed at which he advances the roller in order to obtain a layer of paint whose thickness is substantially constant over the entire path, since the device adjusts the flow rate as a function of this speed. . He must no longer interrupt his work because he must no longer adjust the flow himself according to the speed of movement of the roller. It is therefore the device itself which follows the rhythm of the user. It should be noted that the GB-A- patent application
2.263.508 décrit un dispositif où l'apport de liquide est déterminé en fonction de la vitesse du mouvement. Toutefois le rouleau qui mesure cette vitesse n'est pas celui qui applique le liquide. Le seul rôle de ce rouleau est de mesurer cette vitesse. Le liquide est lui appliqué à l'aide d'un éjecteur. De plus, ce dispositif ne dispose pas d'une unité de commande qui permet d'ajuster le rapport entre le débit et la vitesse du rouleau. Dans ce dispositif la pompe est entraînée par le mouvement du rouleau ce qui n'est compatible qu'avec des liquides très fluides qui sont sucés et non poussés vers 1 'applicateur.2.263.508 describes a device where the supply of liquid is determined based on the speed of movement. However, the roller which measures this speed is not the one which applies the liquid. The only role of this roller is to measure this speed. The liquid is applied to it using an ejector. In addition, this device does not have a control unit which makes it possible to adjust the ratio between the flow rate and the speed of the roller. In this device, the pump is driven by the movement of the roller, which is only compatible with very fluid liquids which are sucked and not pushed towards the applicator.
Une première forme de réalisation préféren¬ tielle d'un dispositif suivant l'invention est caracté¬ risée en ce que ladite unité de commande est agencée pour démarrer le rappel de liquide lorsque le signal de contrôle indique une valeur correspondante à un arrêt du mouvement. Ce qui permet d'arrêter 1 'apport de produit liquide lors d'un arrêt du rouleau et d'empêcher ainsi soit de sursaturer un endroit de la surface où le rouleau est arrêté soit d'éviter que le produit liquide déborde de 1 'applicateur. En effet, il est nécessaire de décomprimer la colonne de peinture qui s'est établie entre la pompe et le rouleau pour arrêter complètement l'apport de produit fourni au rouleau. De préférence l'unité de commande est agencée pour arrêter ledit rappel de liquide après l'écoulement d'une période de temps prédéterminée compté à partir dudit démarrage. Lorsque le rappel devrait se prolonger trop longtemps la conduite se viderait et il faudrait réamorcer l'apport de produit lorsque les travaux recommencent, causant ainsi une perte de temps. En arrêtant ainsi le rappel on garde du produit dans la conduite et l'utilisateur peut directement recommencer après une interruption même plus longue que la période prédéterminée. Une deuxième forme de réalisation préféren¬ tielle d'un dispositif suivant l'invention est caracté¬ risée en ce que l'unité de commande est pourvue d'un régulateur permettant de modifier le rapport entre ledit débit du liquide et ladite vitesse du mouvement du rouleau sur la surface. Le rapport entre le débit et la vitesse du rouleau définit l'épaisseur de peinture. Le régulateur permet de modifier ce rapport et donc de modifier l'épaisseur de la couche de peinture. Après que le régulateur a été positionné à la valeur choisie, le rapport sera maintenu constant à cette valeur suivant la droite d'asservissement du débit. L'épaisseur choisie de la couche appliquée sur la surface est ainsi obtenue, quelle que soit la vitesse à laquelle l'utilisateur fait avancer le rouleau.A first preferred embodiment of a device according to the invention is characterized in that said control unit is arranged to start the liquid booster when the control signal indicates a value corresponding to a stop of the movement. This makes it possible to stop the supply of liquid product when the roller stops and thus to prevent either oversaturating a place on the surface where the roller is stopped or preventing the liquid product from overflowing from the applicator . Indeed, it is necessary to decompress the column of paint which has been established between the pump and the roller to completely stop the supply of product supplied to the roller. Preferably the control unit is arranged to stop said liquid booster after the expiration of a predetermined period of time counted from said start. When the recall should be prolonged too long, the pipe would empty and the supply of product would have to be restarted when work started again, thus causing a loss of time. By thus stopping the recall, the product is kept in the pipeline and the user can directly start again after an interruption even longer than the predetermined period. A second preferred embodiment of a device according to the invention is characterized in that the control unit is provided with a regulator making it possible to modify the ratio between said flow of the liquid and said speed of movement of the roller on the surface. The ratio of the flow rate to the speed of the roller defines the thickness of the paint. The regulator makes it possible to modify this ratio and therefore to modify the thickness of the paint layer. After the regulator has been positioned at the selected value, the ratio will be kept constant at this value along the flow control line. The chosen thickness of the layer applied to the surface is thus obtained, regardless of the speed at which the user advances the roller.
Une troisième forme de réalisation préféren¬ tielle d'un dispositif suivant l'invention est caracté¬ risée en ce que 1 'applicateur comporte deux rouleaux disposés parallèlement, ladite conduite étant reliée à une cavité interne d'un des rouleaux. Ceci offre l'avan¬ tage qu'un rouleau apporte le liquide et l'autre l'éta¬ lé. Le rouleau qui n'est pas alimenté ne se sature ainsi pas de produit liquide ce qui permet de l'utiliser pleinement pour étaler le liquide et obtenir ainsi une application uniforme du produit liquide.A third preferred embodiment of a device according to the invention is characterized in that the applicator comprises two rollers arranged in parallel, said pipe being connected to an internal cavity of one of the rollers. This offers the advantage that one roller provides the liquid and the other the spread. The roller which is not fed thus does not saturate with liquid product which allows it to be used fully to spread the liquid and thus obtain a uniform application of the liquid product.
Une quatrième unité forme de réalisation préférentielle d'un dispositif suivant l'invention est caractérisée en ce que l'unité d'alimentation comporte au moins deux pompes agencées pour alimenter en produits liquides différents le même applicateur, et ladite unité de commande étant agencée pour régler le débit de chaque pompe individuellement. Ceci permet de mélanger deux produits et de doser l'apport de chaque produit indivi¬ duellement. De préférence ladite pompe est une pompe péristaltique entraînée par un moteur à vitesse régla- ble. Une pompe peristaltique permet de facilement régler le débit, car ce type de pompe volu étrique a un débit proportionnel à la vitesse de rotation du moteur qui 1 'entraîne. Une cinquième forme de réalisation préféren¬ tielle d'un dispositif suivant l'invention est caracté¬ risé en ce que ledit applicateur comporte des écrans de protection montés en parallèle à l'axe du rouleau. Ceci permet de buter contre des plafonds, plinthes ou autres bords contigus sans que le rouleau touche ces bords, ce qui permet d'accroître la vitesse de travail.A fourth unit, a preferred embodiment of a device according to the invention, is characterized in that the supply unit comprises at least two pumps arranged to supply different liquid products to the same applicator, and said control unit being arranged to adjust the flow rate of each pump individually. This makes it possible to mix two products and to dose the contribution of each product individually. Preferably said pump is a peristaltic pump driven by a speed-regulated motor. corn. A peristaltic pump makes it possible to easily regulate the flow rate, because this type of voluetric pump has a flow rate proportional to the speed of rotation of the motor which drives it. A fifth preferred embodiment of a device according to the invention is characterized in that said applicator comprises protective screens mounted in parallel with the axis of the roller. This makes it possible to abut against ceilings, plinths or other contiguous edges without the roller touching these edges, which makes it possible to increase the speed of work.

Dans les dessins une même référence a été attribuée à un même élément ou à un élément analogue. Dans la description qui suit référence est faite à un dispositif destiné à appliquer de la peinture sur une surface. Toutefois, le dispositif suivant l'invention n'est pas limité à l'application de peinture et d'autres produits liquides, comme par exemple de la colle, un décapant, des coatings à base de bitume, peuvent égale¬ ment être appliqués par ce dispositif.In the drawings, the same reference has been assigned to the same element or to an analogous element. In the following description reference is made to a device intended for applying paint to a surface. However, the device according to the invention is not limited to the application of paint and other liquid products, such as glue, a stripper, bitumen-based coatings, can also be applied by this device.
Les figures 1 et 2 représentent un exemple d'un applicateur faisant partie du dispositif selon l'invention. L'applicateur comporte deux rouleaux 2 et 3 disposés parallèlement dont tous deux débordent un peu de l'ouverture du boîtier 1. Le premier rouleau 2, représenté en détail à la figure 3 , comporte une cavité intérieure 21 qui est alimentée en peinture via une conduite d'alimentation 8. La conduite est au moins sur une partie de sa longueur flexible. La peinture est distribuée uniformément sur la périphérie extérieure du rouleau et passe au travers du cylindre perméable 22 qui supporte la peau extérieure 23 du rouleau. La cavité peut être partiellement remplie d'une mousse légère non saturable 24. Le deuxième rouleau 3 étale la peinture déposée par le premier. Le boîtier 1 est guidé par le déplacement des deux rouleaux 2 et 3 de sorte qu'il soit maintenu parallèle à la surface à peindre; il récolte ainsi toutes les éclaboussures de peinture.Figures 1 and 2 show an example of an applicator forming part of the device according to the invention. The applicator comprises two rollers 2 and 3 arranged in parallel, both of which protrude slightly from the opening of the housing 1. The first roller 2, shown in detail in FIG. 3, has an internal cavity 21 which is supplied with paint via a supply line 8. The pipe is at least part of its flexible length. The paint is distributed uniformly over the outer periphery of the roller and passes through the permeable cylinder 22 which supports the outer skin 23 of the roller. The cavity can be partially filled with a light non-saturable foam 24. The second roller 3 spreads the paint deposited by the first. The housing 1 is guided by the movement of the two rollers 2 and 3 so that it is kept parallel to the surface to be painted; he collects all the paint splashes.
Dans l'exemple repris dans les figures 1-3 le dispositif comporte deux rouleaux. Toutefois un dispositif avec un seul rouleau peut également être envisagé. Le dispositif comporterait alors uniquement le rouleau 2. La conduite d'alimentation peut être en partie formée par le manche sur lequel l'applicateur est monté.In the example shown in Figures 1-3 the device comprises two rollers. However, a device with a single roller can also be envisaged. The device would then comprise only the roller 2. The supply line may be partly formed by the handle on which the applicator is mounted.
Le boîtier est pourvu d'écrans de protection 11 montés en parallèle à l'axe 12 du rouleau. Ces écrans permettent d'une part de bien envelopper les rouleaux et d'autre part de buter contre le plafond, des plinthes ou des châssis de portes et de fenêtres ou tout autre bords contigus, sans que les rouleaux touchent ces bords. La vitesse de travail peut ainsi être accrue car l'utilisa- teur devra moins faire attention et ne devra pas masquer ces bords.The housing is provided with protective screens 11 mounted in parallel with the axis 12 of the roller. These screens allow on the one hand to properly wrap the rollers and on the other hand to abut against the ceiling, plinths or window and door frames or any other contiguous edges, without the rollers touching these edges. The working speed can thus be increased because the use the guard should be less careful and should not mask these edges.
L'ensemble 1, 2 et 3 est libre en rotation autour de l'axe 5 faisant partie du manche de l'applica- teur 6. Une ou plusieurs roulettes 4 sont le cas échéant disp tées sur un des côtés du boîtier 1 ce qui permet de peindie plus près des coins et des bords sans trop de précautions. L'axe 5 du manche est disposé au-dessus du centre de gravité de l'ensemble 1,2 et 3 lorsque le bcitier 1 est disposé face ouverte vers le haut. La face ouverte du boîtier vers le haut est donc une position d'équilibre. Ceci veille à ce qu'il n'y ait aucun débordement de peinture lors des diverses manutentions.The assembly 1, 2 and 3 is free to rotate about the axis 5 forming part of the handle of the applicator 6. One or more rollers 4 are optionally provided on one of the sides of the housing 1 which allows painting closer to corners and edges without too much care. The axis 5 of the handle is disposed above the center of gravity of the assembly 1, 2 and 3 when the housing 1 is placed with the face open upwards. The open face of the housing upwards is therefore a position of equilibrium. This ensures that there is no overflow of paint during the various handling operations.
Une commande électrique 7 adaptée au manche 6 permet la mise en marche et l'arrêt de l'unité d'ali¬ mentation de peinture. Un détecteur 9, 10 de vitesse du mouvement du rouleau sur la surface, mesure la vitesse de rotation du premier rouleau 2. Le détecteur comporte par exemple un premier aimant permanent 9 fixé sur le premier rouleau 2 et un deuxième aimant fixé sur le boîtier 1. Chaque fois que le premier aimant passe devant le deuxième, une impulsion est produite. La succession des impulsions ainsi produites forme alors un signal de contrôle correspondant à la vitesse du rouleau sur la surface. La fréquence des impulsions est par exemple transformé en une tension dont le voltage est proportionnel à la fréquence et donc à la vitesse du rouleau. Le débit est asservi à cette mesure de vitesse par l'intermédiaire d'une unité de commande. L'alimentation en peinture du rouleau 2 est assurée par une pompe 38 placée entre la conduite 8 et un réservoir 37 de peinture ou autre produit liquide, comme illustré à la figure 4. La pompe est de préférence une pompe peristaltique car elle permet un contrôle fiable du débit de peinture souhaité par l'utilisateur. En effet, ce type de pompe volumétrique a un débit proportionnel à la vitesse de rotation du moteur 31 qui 1 'entraîne.An electric control 7 adapted to the handle 6 allows the starting and stopping of the paint supply unit. A detector 9, 10 of the speed of movement of the roller on the surface, measures the speed of rotation of the first roller 2. The detector comprises for example a first permanent magnet 9 fixed to the first roller 2 and a second magnet fixed to the housing 1 Each time the first magnet passes in front of the second, an impulse is produced. The succession of pulses thus produced then forms a control signal corresponding to the speed of the roller on the surface. The frequency of the pulses is for example transformed into a voltage whose voltage is proportional to the frequency and therefore to the speed of the roller. The flow rate is controlled by this speed measurement via a control unit. The paint supply to the roller 2 is provided by a pump 38 placed between the line 8 and a reservoir 37 of paint or other liquid product, as illustrated in FIG. 4. The pump is preferably a peristaltic pump because it allows control reliable paint flow rate desired by the user. Indeed, this type of positive displacement pump has a flow proportional to the speed of rotation of the motor 31 which drives it.
Le moteur électrique 31 entraîne, via un réducteur 32, l'axe de la pompe sur lequel sont fixées deux roulettes 36. L'espace réduit entre les roulettes 36 et la gorge du corps de pompe 34 provoque l'écrase¬ ment du tube 35 tel que le tube soit rendu étanche. Le déplacement des roulettes le long du tube 35 provoque le pompage et l'alimentation de la peinture du récipient 37 vers un applicateur via la conduite 8. Le débit de peinture dépend donc uniquement de la vitesse du moteur 31 contrôlée par l'unité de commande 33.The electric motor 31 drives, via a reduction gear 32, the axis of the pump on which two rollers 36 are fixed. The reduced space between the rollers 36 and the groove of the pump body 34 causes the tube 35 to be crushed such that the tube is sealed. The movement of the rollers along the tube 35 causes the paint to be pumped and fed from the container 37 to an applicator via the pipe 8. The paint flow rate therefore depends only on the speed of the motor 31 controlled by the control unit 33.
Comme illustré à la' figure 5 l'unité de commande 33 reçoit le signal de contrôle fourni par le détecteur. Le signal de contrôle est fourni à une résistance variable 41 dont une sortie est reliée à une première entrée d'un circuit comparateur 39. Une seconde entrée du circuit comparateur 39 est reliée au moteur 31 et reçoit un signal indiquant la vitesse du moteur. La résistance variable 41 est commandée à l'aide d'un régulateur 40, qui permet de modifier le rapport entre le débit du liquide et la vitesse du mouvement du rouleau sur la surface. La figure 6 montre un graphique indiquant la relation entre la vitesse de rotation Vr du rouleau et la vitesse de rotation V de la pompe qui est proportionnel au débit du liquide fourni. Le régulateur 40 permet de sélectionner un rapport Vr/V suivant une pente αa, b ou c. Les droites d'asservissement a, b, c indiquent des rapports différents. Avant de commencer ses travaux de peinture, l'utilisateur choisira donc à l'aide du régulateur 40 un rapport Vr/V en fonction de l'épaisseur de la couche à appliquer. Le rapport ainsi indiqué positionnera la résistance variable 41 à une valeur correspondant à ce rapport. Le signal de contrôle fourni par le détecteur de vitesse et le signal indiquant la vitesse du moteur, pondéré par la résistance 41 seront en permanence comparés par le circuit comparateur 39 qui fournit alors à sa sortie un signal de contrôle pour le moteur 31. Lorsque la vitesse du rouleau augmente respectivement diminue, le circuit comparateur 39 constatera une différence entre les signaux fournis à ces entrées et modifiera la vitesse du moteur afin d'égaliser cette différence. Le débit du liquide fourni par la pompe est ainsi contrôlé par le signal de contrôle indiquant la vitesse du rouleau. Puisque le rapport entre le débit et la vitesse du rouleau définit l'épaisseur de peinture et que ce rapport est maintenu constant suivant la droite d'asservissement choisie, l'épaisseur est donc maintenue constante quelle que soit la vitesse à laquelle l'utili- sateur fait avancer le rouleau.As illustrated in FIG. 5, the control unit 33 receives the control signal supplied by the detector. The control signal is supplied to a variable resistor 41, an output of which is connected to a first input of a comparator circuit 39. A second input of the comparator circuit 39 is connected to the motor 31 and receives a signal indicating the speed of the motor. The variable resistor 41 is controlled using a regulator 40, which makes it possible to modify the ratio between the flow rate of the liquid and the speed of movement of the roller on the surface. FIG. 6 shows a graph indicating the relationship between the rotation speed V r of the roller and the rotation speed V of the pump which is proportional to the flow rate of the liquid supplied. The regulator 40 makes it possible to select a ratio V r / V according to a slope αa, b or c. The control lines a, b, c indicate different relationships. Before starting his painting work, the user will therefore choose, with the aid of the regulator 40, a V r / V ratio as a function of the thickness of the layer to be applied. The ratio thus indicated will position the variable resistor 41 at a value corresponding to this ratio. The control signal supplied by the speed sensor and the signal indicating the speed of the motor, weighted by the resistor 41 will be constantly compared by the comparator circuit 39 which then provides at its output a control signal for the motor 31. When the speed of the roller increases respectively decreases, the comparator circuit 39 will notice a difference between the signals supplied to these inputs and will modify the motor speed to equalize this difference. The flow of liquid supplied by the pump is thus controlled by the control signal indicating the speed of the roller. Since the ratio between the flow rate and the speed of the roller defines the thickness of the paint and this ratio is kept constant along the selected servo line, the thickness is therefore kept constant regardless of the speed at which the user sator advances the roller.
L'unité de commande 33 est également agencée pour constater un arrêt momentané du mouvement du rouleau et pour démarrer un rappel du liquide en cas d'arrêt. Lorsque le signal de contrôle fournit à la première entrée du circuit comparateur 39 indique une valeur Vr=0 indiquant l'arrêt du rouleau, le circuit comparateur va produire une impulsion de commande provoquant une rotation en sens inverse du moteur 31. Le moteur va pomper le liquide dans la conduite 8 et le rappeler vers le réservoir 37. Ceci permet de vider le rouleau 2 et d'éviter ainsi un débordement du rouleau suite à des résidus de pression de la pompe ou dans la conduite, ou suite à un rouleau sursaturé mis au repos. Afin d'éviter que ce rappel de produit liquide vienne complètement vider la conduite et néces¬ siterait ainsi une réamorce du dispositif en cas de reprise du travail, le rappel est limité à une période de temps prédéterminée comptée à partir du moment où le sens de rotation du moteur a été inversé. A cette fin, l'unité de commande comporte par exemple un circuit RC calé sur cette période de temps. Au cas où deux ou plusieurs produits liqui¬ des différents doivent être mélangés, le dispositif suivant l'invention peut être équipé de plusieurs pompes, chacune pourvue de leur, propre unité de commande où partagent une unité de commande avec une autre pompe. ,. ' Grâce au dispositif suivant l'invention, aucun contrôle de la viscosité de la peinture n'est requis et celle-ci peut comporter des particules solides sans affecter le fonctionnement de la pompe. De plus, la vidange de la pompe peristaltique et de l'applicateur est simp ifié car le débit de peinture peut être inversé par la marche arrière du moteur et vider ainsi l'appa¬ reillage. Le nettoyage est facilité par un raccord rapide prévu dans la conduite 8 et adaptable à une alimentation d'eau courante. Le changement du tuyau de la pompe peristaltique par un autre facilite un change¬ ment rapide de couleur ou de peinture.The control unit 33 is also arranged to note a temporary stop in the movement of the roller and to start a recall of the liquid in the event of a stop. When the control signal supplied to the first input of the comparator circuit 39 indicates a value V r = 0 indicating the stopping of the roller, the comparator circuit will produce a control pulse causing an opposite rotation of the motor 31. The motor will pump the liquid in line 8 and return it to the reservoir 37. This allows the roller 2 to be emptied and thus prevent the roller from overflowing due to pressure residues from the pump or in the line, or following a roller supersaturated put to rest. In order to prevent this recall of liquid product from completely emptying the pipe and thus necessitating a reboot of the device in the event of resumption of work, the recall is limited to a predetermined period of time counted from the moment when the direction of engine rotation has been reversed. To this end, the control unit comprises for example an RC circuit calibrated on this period of time. If two or more different liqui¬ products must be mixed, the device according to the invention can be equipped with several pumps, each provided with their own control unit where a control unit shares with another pump. ,. ' Thanks to the device according to the invention, no control of the viscosity of the paint is required and it can contain solid particles without affecting the operation of the pump. In addition, the emptying of the peristaltic pump and the applicator is simplified because the paint flow rate can be reversed by reversing the engine and thus emptying the apparatus. Cleaning is facilitated by a quick connector provided in line 8 and adaptable to a running water supply. Changing the hose of the peristaltic pump with a different one facilitates a rapid change of color or paint.
Le boîtier de l'applicateur contenant les deux rouleaux supprime les problèmes d'éclaboussures et les masquages ne sont plus nécessaires. L'applicateur réalise en une opération alimentation et étalement de la peinture grâce au double rouleau. Dés lors, l'applica¬ tion de la peinture sur un mur peut se réaliser par des mouvements de va et vient de 1 'extrémité supérieure du mur à son extrémité inférieure. Un manche télescopique est préférentiellement utilisé car il permet l'utilisa¬ tion des deux mains de l'opérateur. Pour peindre les plafonds, le manche extensible est adaptable en position verticale à un support roulant. Il n'est plus nécessaire de croiser la peinture car l'étalement est uniforme dès le premier passage. Une couche de peinture suffit parfois car l'apport de peinture peut être réglé de façon à ce qu' il soit nettement plus important qu'avec un rouleau classique sans affecter le résultat final. Le rendement et le confort du peintre sont donc nettement améliorés et la qualité du travail supérieure. Un type particulier de rouleau tel que présenté à la figure 7 est de préférence de forme conique tronquée dont les bases circulaires 50, 51 sont imperméables au produit liquide utilisé. Ce type de rouleau permet de réaliser les découpes rapides et avec la même pompe. Le rouleau standard cylindrique réalise les surfaces à l'exception des découpes. Le. connecteur rapide sur la conduite 8 permet de connecter le rouleau conique en lieu et place du rouleau standard. The applicator housing containing the two rollers eliminates splashing problems and masking is no longer necessary. The applicator performs in one operation feeding and spreading the paint thanks to the double roller. Therefore, the applica¬ tion of paint on a wall can be achieved by back and forth movements from one upper end of the wall to its lower end. A telescopic handle is preferably used because it allows the use with both hands of the operator. To paint ceilings, the extendable handle is adaptable in a vertical position to a rolling support. It is no longer necessary to cross the paint because the spread is uniform from the first pass. A coat of paint is sometimes enough because the supply of paint can be adjusted so that it is significantly larger than with a conventional roller without affecting the final result. The performance and comfort of the painter are therefore significantly improved and the quality of work superior. A particular type of roller as shown in FIG. 7 is preferably of truncated conical shape, the circular bases 50, 51 of which are impermeable to the liquid product used. This type of roller enables quick cuts to be made with the same pump. The standard cylindrical roller realizes the surfaces with the exception of the cuts. The. quick connector on line 8 allows the tapered roller to be connected in place of the standard roller.
