Chaque mélange est déterminé à partir d’une formule définie par le fabricant de peintures, cette formule donnant la masse de chaque teinte de base à incorporer pour une quantité donnée de mélange à obtenir. Cette préparation implique couramment le mélange de cinq à six teintes de base pour obtenir la nuance particulière prescrite par le fabricant de peintures. Pour réaliser ces opérations, un dispositif rotatif de distribution de produits liquides comprenant une pluralité de conteneurs stockant différentes teintes de base respectives est connu comme l’illustrent par exemple les brevets FR 2 983 089 ou EP 2 651 574. Un conteneur comprend par exemple, une alvéole définissant un volume intérieur clos logeant de manière étanche une poche déformable contenant l’une des teintes de base. Chaque poche est munie d’une valve de dosage permettant l’expulsion de la teinte de base correspondante vers un récipient collecteur d’un poste de dosage du dispositif lorsque le volume intérieur de l’alvéole est mis sous pression et la valve ouverte. In this area, bodybuilders develop the amounts of paint needed to repair a body by mixing a number of base colors. Each mixture is determined from a formula defined by the paint manufacturer, this formula giving the mass of each base color to be incorporated for a given quantity of mixture to be obtained. This preparation commonly involves mixing five to six basic shades to obtain the particular shade prescribed by the paint manufacturer. To carry out these operations, a rotary device for dispensing liquid products comprising a plurality of containers storing different respective basic colors is known, for example as illustrated by the patents FR 2 983 089 or EP 2 651 574. A container comprises, for example, a cell defining an enclosed interior volume sealingly accommodating a deformable pocket containing one of the basic colors. Each pocket is equipped with a metering valve allowing the expulsion of the corresponding basic shade towards a collecting container of a metering station of the device when the interior volume of the cell is pressurized and the valve open.
Les conteneurs sont fixés, selon une configuration circonférentielle, sur un carrousel à axe de rotation horizontal. Le carrousel est indexé en rotation de sorte que la valve de dosage d’un conteneur sélectionné soit amenée dans une position de prélèvement, en regard du récipient collecteur. Des moyens de dosage commandent alors l’expulsion d’une dose prédéterminée de teinte dans le récipient collecteur. Les valves de dosage sont disposées le long du carrousel selon une ou plusieurs rangées circonférentielles parallèles, les valves de chaque rangée décrivant un trajet circulaire lorsque le carrousel du dispositif de distribution est mis en rotation. Une valve de dosage comprend un conduit terminé par un bout, généralement de forme sphérique, percé d’un trou de passage communiquant avec l’intérieur de la poche déformable de manière à permettre l’expulsion vers le récipient collecteur de la teinte de base contenue dans la poche. Le trou de passage peut être ouvert ou fermé à volonté au moyen d’un obturateur couplé à une bobine électromagnétique placée autour du conduit de valve et apte à entraîner l’obturateur dans un mouvement de translation parallèle au conduit sous l’action des moyens de dosage précités. En pratique, on constate qu’après prélèvement il peut rester des traces de peinture sur le bout sphérique de la valve au niveau du trou de passage et de l’obturateur. En séchant, ces salissures risquent de boucher le trou de passage et donc de provoquer des problèmes de dosage liés à une valve dont le trou de passage serait partiellement ou complètement bouché. A cela s’ajoutent les projections de peinture provenant d'éclaboussures au moment de l'éjection de la dose de peinture dans le récipient collecteur, qui peuvent venir souiller la valve. En particulier, de telles projections sont susceptibles de poser des problèmes de fonctionnement du dispositif par encrassement du conduit de valve au niveau de la bobine, pouvant causer des collages, voire même des arrachements de valve. The containers are fixed, in a circumferential configuration, on a carousel with horizontal axis of rotation. The carousel is indexed in rotation so that the metering valve of a selected container is brought into a sampling position, facing the collecting container. Metering means then control the expulsion of a predetermined dose of shade in the collecting container. The metering valves are arranged along the carousel in one or more parallel circumferential rows, the valves of each row describing a circular path when the carousel of the dispensing device is rotated. A metering valve comprises a conduit terminated by a tip, generally of spherical shape, pierced with a through hole communicating with the interior of the deformable bag so as to allow expulsion towards the collecting container of the basic shade contained in the pocket. The through hole can be opened or closed at will by means of a shutter coupled to an electromagnetic coil placed around the valve duct and capable of driving the shutter in a translational movement parallel to the duct under the action of the means of aforementioned dosage. In practice, we find that after sampling there may be traces of paint on the spherical end of the valve at the passage hole and the shutter. When drying, this dirt risks blocking the passage hole and therefore causing metering problems linked to a valve whose passage hole is partially or completely blocked. To this are added the splashes of paint coming from splashes when the dose of paint is ejected into the collecting container, which can contaminate the valve. In particular, such projections are likely to pose operating problems of the device by fouling of the valve duct at the level of the coil, which can cause sticking, or even valve tearing.
Pour remédier à ces difficultés, les dispositifs rotatifs de distribution de produits liquides sont généralement munis de moyens de nettoyage. Ces moyens de nettoyage peuvent être formés par une simple brosse apte à être en contact de friction avec le bout de chaque valve au cours de l’entraînement en rotation du carrousel comme l’illustre le brevet EP 2 651 574. Le nettoyage est dans ce cas un nettoyage dit « à sec ». Toutefois, un tel nettoyage n’est pas toujours efficace. Une solution plus efficace consiste à pratiquer un nettoyage dit "humide". Ce nettoyage humide consiste à laver les conduits et les bouts sphériques de valve au moyen de brosses ou d’éponges mobiles, généralement rotatives, disposant d’un système d’humidification avec une solution de nettoyage, qui peut être à base d'eau, dans le cas de peinture hydrosoluble ou un solvant en particulier à base d'acétone, dans le cas de peinture solvantée. Dans ce cas, l’enceinte de nettoyage est stationnaire et disposée sur la trajectoire suivie par les valves. Cette enceinte de nettoyage est le plus souvent constamment ouverte, ce qui entraîne un risque de pollution de l’atmosphère autour de l’enceinte et/ou du contenu de l’enceinte. La solution de nettoyage humide ne donne donc pas, dans sa conception actuelle, satisfaction. Un but de l’invention est de proposer un dispositif de stockage et de distribution de produits liquides du type précité dont la conception permet un nettoyage dit humide dans des conditions améliorées. To overcome these difficulties, rotary devices for dispensing liquid products are generally provided with cleaning means. These cleaning means can be formed by a simple brush capable of being in friction contact with the end of each valve during the rotational drive of the carousel as illustrated in patent EP 2 651 574. The cleaning is in this in case of a so-called “dry” cleaning. However, such cleaning is not always effective. A more effective solution is to practice so-called "wet" cleaning. This wet cleaning consists in washing the conduits and the spherical ends of the valve by means of brushes or mobile sponges, generally rotary, having a humidification system with a cleaning solution, which can be water-based, in the case of water-soluble paint or a solvent in particular based on acetone, in the case of solvent-based paint. In this case, the cleaning chamber is stationary and arranged on the path followed by the valves. This cleaning enclosure is most often constantly open, which leads to a risk of pollution of the atmosphere around the enclosure and / or of the contents of the enclosure. The wet cleaning solution is therefore not satisfactory in its current design. An object of the invention is to provide a device for storing and distributing liquid products of the aforementioned type, the design of which allows so-called wet cleaning under improved conditions.
A cet effet, l’invention a pour objet un dispositif de stockage et de distribution de produits liquides stockés dans des conteneurs équipés de valves de dosage, ledit dispositif comprenant : To this end, the subject of the invention is a device for the storage and distribution of liquid products stored in containers equipped with metering valves, said device comprising:
- un support mobile porte-valves,  - a mobile valve holder support,

caractérisé en ce que l'enceinte est munie d'une ouverture à travers laquelle une valve est apte à faire saillie à l'intérieur de l'enceinte, en ce que l'ouverture de l'enceinte est une ouverture obturable équipée d'un organe de fermeture monté mobile entre une position fermée et une position ouverte de l'ouverture, en ce que le dispositif comprend des moyens d’entraînement en déplacement de l’enceinte entre une position écartée et une position rapprochée du support porte-valves pour permettre, au cours du déplacement, l'entrée ou la sortie de l'une des valves de ladite enceinte, et en ce que l'organe de fermeture de l'ouverture de l'enceinte est configuré pour passer de la position fermée à la position ouverte de l'ouverture de l'enceinte lors du passage de l'enceinte de la position écartée du support porte-valves à la position rapprochée dudit support porte-valves. La présence d’un organe de fermeture de l’enceinte permet l’utilisation de tout type de solution de nettoyage y compris solvantée sans nuire à l’environnement. La réalisation d’une enceinte mobile permet d’utiliser le mouvement de l’enceinte pour assurer de manière fiable le passage de l’organe de fermeture de l’ouverture de l’enceinte de la position fermée à la position ouverte. L'enceinte fait ainsi fonction d'actionneur de l'organe de fermeture de l'ouverture de l'enceinte. L'organe de fermeture est configuré pour passer de la position fermée à la position ouverte de l'ouverture de l'enceinte sous l'action de l'enceinte. Le dispositif comprend des moyens d'entraînement en déplacement de l'enceinte et des moyens d'entraînement en déplacement de l'organe de nettoyage distincts des moyens d'entraînement en déplacement de l'enceinte.

The presence of a closure member of the enclosure allows the use of any type of cleaning solution including solvent without harming the environment. The realization of a movable enclosure allows the movement of the enclosure to be used to reliably ensure the passage of the closing member of the opening of the enclosure from the closed position to the open position. The enclosure thus acts as an actuator for the member for closing the opening of the enclosure. The closure member is configured to pass from the closed position to the open position of the opening of the enclosure under the action of the enclosure. The device comprises means for driving the movement of the enclosure and means for driving the movement of the cleaning member separate from the means for driving the movement of the enclosure. The cleaning member can therefore be moved in stationary position of the enclosure.

Selon un mode de réalisation de l’invention, le support porte-valves est un support rotatif sur lequel les valves, organisées en au moins une rangée, sont disposées selon au moins une rangée circonférentielle et le système de nettoyage est disposé à côté d’un poste de dosage et est positionnable à l’intérieur de ladite au moins une rangée de valves. According to one embodiment of the invention, the valve holder support is a rotary support on which the valves, organized in at least one row, are arranged in at least one circumferential row and the cleaning system is arranged next to a dosing station and is positionable inside said at least one row of valves.
Selon un mode de réalisation de l’invention, le support porte-valves est monté mobile en va-et-vient et les valves, organisées en au moins une rangée, sont disposées en une ou plusieurs rangées rectilignes sur ledit support porte-valves. According to one embodiment of the invention, the valve holder support is mounted to move back and forth and the valves, organized in at least one row, are arranged in one or more rectilinear rows on said valve holder support.
Selon un mode de réalisation de l’invention, le dispositif comprend des moyens d’entraînement en déplacement du support porte-valves et une unité de pilotage des moyens d’entraînement en déplacement du support porte-valves. Selon un mode de réalisation de l’invention, le dispositif comprend un capteur de détection de la position de l’enceinte de nettoyage et l’unité de pilotage des moyens d’entraînement en déplacement du support porte- valves est configurée pour empêcher le déplacement du support porte- valves à l’état rapproché de l’enceinte du support porte-valves. According to one embodiment of the invention, the device comprises means for driving the displacement of the valve holder support and a unit for controlling the means for driving the movement of the valve holder support. According to one embodiment of the invention, the device comprises a sensor for detecting the position of the cleaning chamber and the control unit for the means for driving the displacement of the valve support support is configured to prevent displacement of the valve holder support in the close state of the valve holder support enclosure.
Selon un mode de réalisation de l’invention, le dispositif comprend un mécanisme de commande en ouverture/fermeture d’une valve et l’unité de pilotage des moyens d’entraînement en déplacement du support porte- valves est configurée pour, après chaque ouverture d’une valve à l’aide du mécanisme de commande en ouverture/fermeture d’une valve, commander le déplacement du support porte-valves en direction du système de nettoyage pour un nettoyage de la valve venant d’être ouverte. According to one embodiment of the invention, the device comprises a mechanism for controlling the opening / closing of a valve and the unit for controlling the means for driving the displacement of the valve holder support is configured for, after each opening a valve using the valve opening / closing control mechanism, control the movement of the valve holder support towards the cleaning system for cleaning the valve that has just been opened.
L’invention a encore pour objet un procédé de nettoyage des valves de dosage de conteneurs équipant un dispositif de stockage et de distribution de produits liquides stockés dans lesdits conteneurs, caractérisé en ce que le dispositif de stockage et de distribution de produits liquides étant du type précité, le procédé comprend une étape d’ouverture de l’organe de fermeture de l’ouverture de l’enceinte par déplacement de l’enceinte dans le sens d’un rapprochement du support porte-valves. L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels : The invention also relates to a method for cleaning the metering valves of containers fitted with a device for storing and distributing liquid products stored in said containers, characterized in that the device for storing and distributing liquid products being of the type aforementioned, the method comprises a step of opening the member for closing the opening of the enclosure by displacement of the enclosure in the direction of a bringing together of the valve support support. The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
La figure 1 représente une vue de face d’un dispositif de stockage et de distribution de produits liquides conforme à l’invention dans lequel les valves sont disposées en rangée circonférentielle ; La figure 2 représente une vue arrière d’un dispositif de stockage et de distribution de produits liquides conforme à l’invention ; Les figures 3 à 5 représentent, sous forme de vues partielles de détail de la figure 1 , le déplacement de l’enceinte du dispositif de stockage et de distribution de produits liquides de la figure 1 pour le passage de la position fermée à la position ouverte de l’organe de fermeture de l’ouverture de ladite enceinte ; FIG. 1 represents a front view of a device for storing and distributing liquid products according to the invention in which the valves are arranged in a circumferential row; FIG. 2 represents a rear view of a device for storing and distributing liquid products according to the invention; Figures 3 to 5 show, in the form of partial detail views of Figure 1, the displacement of the enclosure of the device for storage and distribution of liquid products of Figure 1 for the transition from the closed position to the open position of the member for closing the opening of said enclosure;

La figure 9 représente une vue de face d’un dispositif de stockage et de distribution de produits liquides conforme à l’invention dans lequel les valves sont disposées en une rangée rectiligne. FIG. 9 represents a front view of a device for storing and distributing liquid products according to the invention in which the valves are arranged in a rectilinear row.
Comme mentionné ci-dessus, le dispositif 1 , objet de l'invention, est plus particulièrement destiné à permettre le stockage et la distribution de produits liquides, tels que des teintes de base pour des peintures, stockés dans des conteneurs 30 équipés de valves 31 de dosage. Ces conteneurs 30 peuvent affecter un grand nombre de formes. Des exemples sont fournis dans les brevets EP 2.135.668, EP 2.651.574 et FR 2.983.089. As mentioned above, the device 1, object of the invention, is more particularly intended to allow the storage and distribution of liquid products, such as base colors for paints, stored in containers 30 fitted with valves 31 dosing. These containers 30 can have a large number of shapes. Examples are provided in patents EP 2,135,668, EP 2,651,574 and FR 2,983,089.
En pratique, ces conteneurs 30 comprennent au moins une poche souple équipée d'une valve 31 de dosage. Cette poche souple peut être associée à un suremballage ou logée dans une alvéole, faisant office de suremballage, du dispositif 1 de stockage et de distribution. La vidange de la poche s'opère par compression de la poche comme cela est décrit dans les documents précités à l'aide d'un système d'alimentation en fluide sous pression équipant le dispositif 1 de stockage et de distribution. In practice, these containers 30 include at least one flexible pocket fitted with a metering valve 31. This flexible bag can be associated with an overwrap or housed in a cell, acting as an overwrap, of the storage and distribution device 1. The bag is emptied by compression of the bag as described in the above documents using a pressurized fluid supply system fitted to the storage and distribution device 1.
Le dispositif 1 de stockage et de distribution de produits liquides comprend donc, pour la réception des conteneurs 30, un support 2 mobile porte- valves. Ce support 2 porte-valves peut affecter un grand nombre de formes. The device 1 for storage and distribution of liquid products therefore comprises, for the reception of the containers 30, a mobile support 2 for valve carriers. This support 2 valve holders can affect a large number of forms.
Indépendamment de la conception du support 2 porte-valves, les valves 31 de dosage sont organisées sur le support 2 porte-valves en au moins une rangée de valves. Ainsi, dans l'exemple représenté à la figure 1 , le support 2 porte-valves affecte la forme d'une roue sur laquelle les valves 31 sont disposées selon au moins une rangée circonférentielle, chaque valve étant disposée sur un rayon de la roue. Dans l'exemple représenté à la figure 9, les valves 31 sont disposées en au moins une rangée rectiligne sur le support 2 porte-valves. Regardless of the design of the support 2 valve holders, the metering valves 31 are organized on the support 2 valve holders in at least one row of valves. Thus, in the example shown in FIG. 1, the support 2 valve holder assumes the shape of a wheel on which the valves 31 are arranged in at least one circumferential row, each valve being arranged on a radius of the wheel. In the example shown in Figure 9, the valves 31 are arranged in at least one straight row on the support 2 valve holders.
Le dispositif 1 comprend des moyens 15 d'entraînement en déplacement du support 2 porte-valves et une unité 18 de pilotage des moyens 15 d'entraînement en déplacement du support 2 porte-valves. Dans l'exemple représenté à la figure 1 , le support 2 porte-valves est un support rotatif. Les moyens 15 d'entraînement en rotation du support 2 porte-valves peuvent comprendre un moteur d'entraînement en rotation de pignons venant en prise avec le contour externe de la roue constitutive du support 2 porte-valves comme décrit dans le brevet FR 2.983.089. The device 1 comprises means 15 for driving the displacement of the support 2 valve holders and a unit 18 for controlling the means 15 for driving the displacement of the support 2 valve holders. In the example shown in Figure 1, the support 2 valve holder is a rotary support. The means 15 for rotating the support 2 valve holder may comprise a motor for driving the rotation of pinions engaging with the external contour of the wheel constituting the support 2 valve holder as described in patent FR 2 983. 089.
L'unité 18 de pilotage se présente, quant à elle, sous la forme d’un système électronique et/ou informatique qui comprend par exemple un microprocesseur et une mémoire de travail. Selon un aspect particulier, l’unité de pilotage peut se présenter sous la forme d’un automate programmable. The piloting unit 18 is in the form of a electronic and / or computer system which includes for example a microprocessor and a working memory. According to a particular aspect, the control unit can be in the form of a programmable controller.
Autrement dit, les fonctions et étapes décrites peuvent être mises en œuvre sous forme de programme informatique ou via des composants matériels (p. ex. des réseaux de portes programmables). En particulier, les fonctions et étapes opérées par l’unité de pilotage ou ses modules peuvent être réalisées par des jeux d’instructions ou modules informatiques implémentés dans un processeur ou contrôleur ou être réalisées par des composants électroniques dédiés ou des composants de type FPGA ou ASIC. Il est aussi possible de combiner des parties informatiques et des parties électroniques. In other words, the functions and steps described can be implemented in the form of a computer program or via hardware components (eg networks of programmable doors). In particular, the functions and steps operated by the control unit or its modules can be performed by sets of instructions or computer modules implemented in a processor or controller or be performed by dedicated electronic components or components of the FPGA type or ASIC. It is also possible to combine computer parts and electronic parts.
Lorsqu’il est précisé que l’unité ou des moyens ou modules de ladite unité sont configurés pour réaliser une opération donnée, cela signifie que l’unité comprend des instructions informatiques et les moyens d’exécution correspondants qui permettent de réaliser ladite opération et/ou que l’unité comprend des composants électroniques correspondants. When it is specified that the unit or the means or modules of said unit are configured to perform a given operation, this means that the unit includes computer instructions and the corresponding execution means which make it possible to carry out said operation and / or that the unit includes corresponding electronic components.
L'unité 18 de pilotage est donc configurée pour amener la valve 31 de dosage de chaque conteneur 30 nécessaire à la réalisation du produit final en regard d'un poste 14 de dosage logé à l'intérieur de la roue constitutive du support 2 porte-valves. The control unit 18 is therefore configured to bring the metering valve 31 of each container 30 necessary for the production of the final product opposite a metering station 14 housed inside the wheel constituting the support 2 holder valves.
Ce poste 14 de dosage, qui comprend un récipient collecteur et des moyens de pesée du contenu du récipient collecteur, est bien connu à ceux versés dans cet art et ne sera donc pas décrit en détail. Ce poste 14 de dosage est animé d'un mouvement de monte et baisse pour venir coiffer la valve 31 par un mécanisme 17 de commande en ouverture de valve équipant le poste 14 de dosage. This dosing station 14, which comprises a collecting container and means for weighing the content of the collecting container, is well known to those versed in this art and will therefore not be described in detail. This dosing station 14 is moved up and down to come cover the valve 31 by a mechanism 17 for controlling the valve opening fitted to the dosing station 14.
En effet, le poste 14 de dosage est généralement équipé d'un mécanisme 17 de commande en ouverture/fermeture de valves également bien connu et décrit, par exemple, dans le brevet EP 1.975.486. Ce mécanisme de commande en ouverture/fermeture de valves peut être formé par une bobine électrique cylindrique, telle qu'un solénoïde, apte à entourer la valve et capable d'induire un champ magnétique au niveau de la valve équipée d'un obturateur chargé par ressort et sensible audit champ magnétique. In fact, the dosing station 14 is generally equipped with a mechanism 17 for controlling the opening / closing of valves which is also well known and described, for example, in patent EP 1,975,486. This valve opening / closing control mechanism can be formed by a cylindrical electric coil, such as a solenoid, capable of surrounding the valve and capable of inducing a magnetic field at the level of the valve equipped with a shutter charged by spring and sensitive to said magnetic field.
Dans l'exemple représenté à la figure 9 où les valves sont disposées en au moins une rangée rectiligne, les moyens 15 d'entraînement en déplacement du support 2 porte-valves sont des moyens d'entraînement en déplacement en va-et-vient du support 2 porte-valves. Ces moyens 15 d'entraînement en déplacement du support 2 porte-valves peuvent, dans ce cas, être formés par un vérin double effet disposé entre le support 2 porte-valves et un châssis stationnaire. A nouveau, l'unité de pilotage du vérin double effet peut se présenter sous la forme d'un système électronique et/ou informatique comme décrit ci-dessus et peut être du même type que celle décrite dans le cadre d'un support 2 porte-valves rotatif. De même, le poste 14 de dosage qui est généralement situé sous le support 2 porte-valves peut être du même type que celui décrit ci- dessus pour un support porte-valves rotatif. In the example shown in FIG. 9 where the valves are arranged in at least one rectilinear row, the means 15 for driving the displacement of the support 2 valve holder are means for driving the reciprocating movement of the support 2 valve holders. These means 15 for moving the support 2 valve holder in displacement can, in this case, be formed by a double-acting cylinder arranged between the support 2 valve holder and a stationary frame. Again, the control unit of the double-acting cylinder can be in the form of an electronic and / or computer system as described above and can be of the same type as that described in the context of a 2-door support. - rotary valves. Similarly, the metering station 14 which is generally located under the support 2 valve holder can be of the same type as that described above for a rotary valve holder support.
Le dispositif 1 de stockage et de distribution de produits liquides comprend encore un système 3 de nettoyage des valves 31. The device 1 for storing and distributing liquid products also comprises a system 3 for cleaning the valves 31.
L'unité 18 de pilotage des moyens 15 d'entraînement en déplacement du support 2 porte-valves est configurée pour, après chaque ouverture d'une valve 31 à l'aide du mécanisme 17 de commande en ouverture/fermeture d'une valve, commander le déplacement du support 2 porte-valves en direction du système 3 de nettoyage pour un nettoyage de la valve 31 venant d'être ouverte. The unit 18 for controlling the means 15 for driving the displacement of the support 2 valve holder is configured for, after each opening of a valve 31 using the mechanism 17 for opening / closing a valve, controlling the movement of the support 2 valve holders in the direction of the cleaning system 3 for cleaning the valve 31 which has just been opened.
Dans les exemples représentés, le système 3 de nettoyage est disposé à côté du poste 14 de dosage et est positionnable à l'intérieur de la rangée de valves dans le cas d'une rangée de valves en disposition circonférentielle ou sous la rangée de valves dans le cas d'une rangée de valves rectiligne. In the examples shown, the cleaning system 3 is arranged next to the metering station 14 and can be positioned inside the row of valves in the case of a row of valves in circumferential arrangement or under the row of valves in the case of a straight row of valves.
Le système 3 de nettoyage des valves est couplé à une structure 4 support formée ici par une partie du bâti du poste 14 de dosage. Ainsi, dans certaines installations, comme celle représentée, le poste 14 de dosage peut être amené à se déplacer. Le système 3 de nettoyage suit ce déplacement. En variante, la structure 4 support du système 3 de nettoyage peut être indépendante du poste 14 de dosage. The valve cleaning system 3 is coupled to a support structure 4 formed here by a part of the frame of the dosing station 14. Thus, in certain installations, such as that shown, the dosing station 14 may have to move. The cleaning system 3 follows this movement. As a variant, the support structure 4 of the cleaning system 3 can be independent of the dosing station 14.
Indépendamment de la conception de la structure 4 support, le système 3 de nettoyage comprend une enceinte 5 et un organe 6 de nettoyage logé à l'intérieur de l'enceinte 5 et des moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage à l'intérieur de ladite enceinte 5. Regardless of the design of the support structure 4, the cleaning system 3 comprises an enclosure 5 and a cleaning member 6 housed inside the enclosure 5 and means 7 for driving the member 6 to move. cleaning inside said enclosure 5.
L'enceinte 5 se présente ici sous forme d'une enceinte de forme générale parallélépipédique. L'organe 6 de nettoyage logé dans l'enceinte est ici un organe 6 rotatif formé par une brosse à poils radiaux rotative. Cet organe 6 rotatif est monté solidaire en rotation d'un axe 13 support qui fait saillie de l'enceinte et dont le rôle sera décrit ci-après. The enclosure 5 is presented here in the form of an enclosure of generally parallelepiped shape. The cleaning member 6 housed in the enclosure is here a rotary member 6 formed by a rotating radial bristle brush. This rotary member 6 is mounted integral in rotation with a support pin 13 which projects from the enclosure and whose role will be described below.
L'enceinte 5 est remplie d'une solution 32 de nettoyage des valves. Cette solution 32 de nettoyage peut comprendre des composés organiques volatils. Ainsi, l'organe 6 de nettoyage est immergé au moins partiellement dans ladite solution de nettoyage. The enclosure 5 is filled with a solution 32 for cleaning the valves. This cleaning solution 32 may include organic compounds volatile. Thus, the cleaning member 6 is at least partially immersed in said cleaning solution.
L'enceinte 5 est munie d'une ouverture 8 à travers laquelle une valve 31 est apte à faire saillie à l'intérieur de l'enceinte. A cet effet, le dispositif 1 comprend des moyens 10 d'entraînement en déplacement de l'enceinte 5 entre une position écartée et une position rapprochée du support 2 porte- valves pour permettre au cours du déplacement l'entrée ou la sortie de l'une des valves 31 de ladite enceinte. The enclosure 5 is provided with an opening 8 through which a valve 31 is capable of projecting inside the enclosure. To this end, the device 1 comprises means 10 for driving the enclosure 5 in displacement between a spaced-apart position and a position brought closer to the support 2 valve holders to allow during movement the entry or exit of the one of the valves 31 of said enclosure.
Ces moyens 10 d'entraînement en déplacement de l'enceinte 5 entre une position écartée et une position rapprochée du support 2 porte-valves comprennent au moins un actionneur 100, tel qu'un vérin disposé entre l'enceinte 5 et la structure 4 support du système 3 de nettoyage. These means 10 for driving the movement of the enclosure 5 between a separated position and a position close to the support 2 valve holders comprise at least one actuator 100, such as a jack disposed between the enclosure 5 and the support structure 4 of the cleaning system 3.
Dans l'exemple représenté, le corps du vérin 100 est couplé à la structure 4 support du système 3 de nettoyage et la tige du vérin 100 est couplée à l'enceinte 5. Ainsi la rentrée de la tige du vérin provoque l'écartement de l'enceinte 5 d'une valve 31 positionnée en regard de l'enceinte, tandis que la sortie de la tige du vérin permet un rapprochement de l'enceinte d'une valve 31 du support 2 porte-valves jusqu'à une position dans laquelle la valve 31 s'étend partiellement à l'intérieur de l'enceinte 5 comme illustré à la figure 5. In the example shown, the cylinder body 100 is coupled to the support structure 4 of the cleaning system 3 and the cylinder rod 100 is coupled to the enclosure 5. Thus the retraction of the cylinder rod causes the spacing of the enclosure 5 of a valve 31 positioned opposite the enclosure, while the outlet of the actuator rod allows the enclosure of a valve 31 to be brought closer to the support 2 valve holders to a position in which the valve 31 partially extends inside the enclosure 5 as illustrated in FIG. 5.
L'ouverture 8 de l'enceinte à travers laquelle une valve 31 est apte à faire saillie à l'intérieur de l'enceinte est une ouverture 8 obturable équipée d'un organe 9 de fermeture. L'organe 9 de fermeture est monté mobile entre une position fermée et une position ouverte de l'ouverture 8 de l'enceinte 5. De préférence, l'enceinte 5 est étanche à l'état fermé de l'organe 9 de fermeture de l'ouverture 8 de l'enceinte 5. De manière caractéristique à l'invention, l'organe 9 de fermeture de l'ouverture de l'enceinte 5 est configuré pour passer de la position fermée à la position ouverte de l'ouverture 8 de l'enceinte 5 lors du passage de l'enceinte 5 de la position écartée du support 2 porte-valves à la position rapprochée du support 2 porte-valves. Ladite enceinte 5 fait office de pousseur sur l'organe 9 de fermeture de l'ouverture de l'enceinte 5. The opening 8 of the enclosure through which a valve 31 is able to project inside the enclosure is a closable opening 8 fitted with a closure member 9. The closure member 9 is mounted movable between a closed position and an open position of the opening 8 of the enclosure 5. Preferably, the enclosure 5 is sealed in the closed state of the member 9 for closing the opening 8 of the enclosure 5. Typically in the invention, the member 9 for closing the opening of the enclosure 5 is configured to pass from the closed position to the open position of the opening 8 of the enclosure 5 when the enclosure 5 passes from the position separated from the support 2 valve holders to the position close to the support 2 valve holders. Said enclosure 5 acts as a pusher on the member 9 for closing the opening of the enclosure 5.
Cet organe 9 de fermeture se présente sous forme d'un simple bouchon plat muni d'un joint venant en position fermée à recouvrement de l'ouverture 8 de l'enceinte 5. Cet organe 9 de fermeture de l'ouverture 8 de l'enceinte 5 est couplé à la structure support 4 par une liaison 11 comprenant une liaison 110 pivot chargée par ressort. This closure member 9 is in the form of a simple flat plug provided with a seal coming in the closed position covering the opening 8 of the enclosure 5. This closure member 9 for closing the opening 8 of the enclosure 5 is coupled to the support structure 4 by a link 11 comprising a pivot link 110 loaded by spring.
Dans l'exemple représenté, la liaison 11 comprend un bras 1101 équipé à une extrémité de l'organe 9 de fermeture de l'ouverture 8 de l'enceinte et relié à son extrémité opposée à la structure 4 support. Ce bras 1101 intègre une charnière 1100 formant la liaison 110 pivot de ladite liaison 11. Cette charnière 1100 est une charnière de type piano. Cette charnière est, au niveau de son axe pivot, équipée du ressort 12. In the example shown, the link 11 comprises an arm 1101 fitted at one end of the member 9 for closing the opening 8 of the enclosure and connected at its end opposite to the support structure 4. This arm 1101 incorporates a hinge 1100 forming the pivot connection 110 of said connection 11. This hinge 1100 is a piano-type hinge. This hinge is, at its pivot axis, fitted with spring 12.
Ce ressort 12 est un ressort hélicoïdal en épingle à cheveux s'enroulant autour de la broche de liaison des lames de la charnière et prenant appui par chacune de ses extrémités sur une lame de la charnière, lesdites lames de la charnière étant reliées entre elles par la broche de la charnière. Le ressort 12 est ainsi configuré pour rappeler l'organe 9 de fermeture en position fermée. This spring 12 is a helical spring in a hairpin winding around the connecting pin of the hinge blades and bearing at each of its ends on a hinge blade, said hinge blades being connected together by the hinge pin. The spring 12 is thus configured to recall the closing member 9 in the closed position.
L'enceinte 5 exerce, quant à elle, la fonction de pousseur et est configurée pour, à l'état entraîné en déplacement dans le sens d'un rapprochement du support 2 porte-valves, exercer une poussée sur l'organe 9 de fermeture à l'encontre de l'action du ressort 12 qui tend à plaquer l'organe 9 de fermeture sur l'ouverture 8 de l'enceinte 5. The enclosure 5, in turn, performs the pusher function and is configured for, in the state driven in displacement in the direction of approximation of the support 2 valve holders, exert a push on the closing member 9 against the action of the spring 12 which tends to press the closing member 9 on the opening 8 of the enclosure 5.
La poussée exercée par l'enceinte 5 sur l'organe 9 de fermeture au cours du déplacement de l'enceinte 5 vers le support 2 porte-valves entraîne, par cassure du bras au niveau de la liaison 110 pivot, le passage de l'organe 9 de fermeture de la position fermée à la position ouverte. Dans la position rapprochée de l'enceinte 5 du support 2 porte-valves, une valve 31 du support 2 porte-valves fait partiellement saillie à l'intérieur de l'enceinte 5 pour y être nettoyée. The thrust exerted by the enclosure 5 on the closure member 9 during the movement of the enclosure 5 towards the support 2 valve holder causes, by breaking the arm at the pivot 110 connection, the passage of the member 9 for closing from the closed position to the open position. In the close position of the enclosure 5 of the support 2 valve holder, a valve 31 of the support 2 valve holder projects partially inside the enclosure 5 to be cleaned there.
A cet effet, le dispositif 1 comprend des moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage. Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage sont configurés pour entraîner en déplacement l'organe 6 de nettoyage à l'intérieur de l'enceinte 5. Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage sont configurés pour entraîner en déplacement l'organe 6 de nettoyage au moins à l'état ouvert de l'organe 9 de fermeture de l'ouverture 8 de l'enceinte 5. Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage sont configurés pour entraîner en déplacement l'organe 6 de nettoyage au moins à l'état stationnaire de l'enceinte 5. L'organe 6 de nettoyage est donc déplaçable indépendamment de l'enceinte 5. To this end, the device 1 comprises means 7 for driving the cleaning member 6 in displacement. These means 7 for driving the cleaning member 6 in displacement are configured to drive the cleaning member 6 for movement inside the enclosure 5. These means 7 for moving the member 6 in movement cleaning means are configured to drive the cleaning member 6 at least in the open state of the member 9 for closing the opening 8 of the enclosure 5. These means 7 for driving the displacement of the the cleaning member 6 are configured to drive the cleaning member 6 in displacement at least in the stationary state of the enclosure 5. The cleaning member 6 can therefore be moved independently of the enclosure 5.
Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage sont embarqués sur une monture comprenant l'enceinte 5. Le déplacement de l'enceinte 5 entraîne donc un déplacement des moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage. Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage suivent donc le déplacement de l'enceinte 5. Ces moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage comprennent au moins un actionneur 72, tel qu'un vérin, configuré pour fonctionner de manière séquencée avec l'actionneur 100 des moyens 10 d'entraînement en déplacement de l'enceinte 5. These means 7 for driving the movement of the cleaning member 6 are carried on a mount comprising the enclosure 5. The movement of the enclosure 5 therefore results in a displacement of the means 7 for driving the movement of the member 6 of cleaning. These means 7 for driving the cleaning member 6 in displacement therefore follow the movement of the enclosure 5. These means 7 for moving the cleaning member 6 in movement comprise at least one actuator 72, such as a jack, configured to operate in sequence with the actuator 100 of the means 10 for driving the displacement of the pregnant 5.
En particulier, l'actionneur 72 des moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage est configuré pour entraîner en déplacement l'organe 6 de nettoyage en position rapprochée de l'enceinte 5 du support 2 porte-valves correspondant à la position de sortie de la tige du vérin constitutif de l'actionneur 100 des moyens 10 d'entraînement en déplacement de l'enceinte 5. In particular, the actuator 72 of the means 7 for driving the cleaning member 6 in displacement is configured to drive the cleaning member 6 for moving in the position close to the enclosure 5 of the support 2 valve holder corresponding to the output position of the rod of the actuator constituting the actuator 100 of the means 10 for driving the enclosure 5 in displacement.
Dans les exemples représentés, l'organe 6 de nettoyage est un organe rotatif monté sur un axe 13 support de manière solidaire en rotation avec ledit axe. En particulier, l'organe 6 de nettoyage affecte la forme d'une brosse à poils radiaux, l'axe 13 support formant le centre de la brosse autour duquel les poils sont à disposition rayonnante. In the examples shown, the cleaning member 6 is a rotary member mounted on a support axis 13 in rotation with said axis. In particular, the cleaning member 6 assumes the shape of a brush with radial bristles, the support axis 13 forming the center of the brush around which the bristles are radiating.
Cet axe 13 support fait saillie à l'extérieur de l'enceinte 5 et est équipé, au niveau de sa partie extérieure à l'enceinte 5, d'un pignon 73 coaxial à l'axe 13 support. Ce pignon 73 est susceptible de venir en prise par engrènement avec une crémaillère 71 couplée à la tige du vérin constitutif de l'actionneur 72 des moyens 7 d'entraînement en déplacement en rotation de l'organe 6 de nettoyage. This support axis 13 protrudes outside the enclosure 5 and is equipped, at its level outside of the enclosure 5, with a pinion 73 coaxial with the support axis 13. This pinion 73 is capable of engaging by meshing with a rack 71 coupled to the rod of the jack constituting the actuator 72 of the means 7 for driving in rotation movement of the cleaning member 6.
Le corps du vérin constitutif de l'actionneur 72 est couplé à l'enceinte 5 ou à une pièce solidaire en déplacement de l'enceinte 5. Ainsi, la rentrée et la sortie de la tige du vérin constitutif de l'actionneur 72 des moyens 7 d'entraînement en déplacement en rotation de l'organe 6 de nettoyage entraînent en va-et-vient la crémaillère 71 qui elle-même entraîne en rotation le pignon 73, et par suite l'organe 6 de nettoyage. Pour parfaire l'ensemble, le dispositif 1 comprend un capteur 16 de détection de la position de l’enceinte 5 de nettoyage et l’unité 18 de pilotage des moyens 15 d’entraînement en déplacement du support 2 porte-valves est configurée pour empêcher le déplacement du support 2 porte-valves à l’état rapproché de l’enceinte 5 du support 2 porte-valves. On évite ainsi un arrachement d'une valve qui s'étendrait en saillie à l'intérieur de l'enceinte 5. Le capteur 16 de détection de la position de l'enceinte 5 de nettoyage peut être un capteur de présence ou de proximité. The body of the actuator constituting the actuator 72 is coupled to the enclosure 5 or to an integral part in displacement of the enclosure 5. Thus, the return and exit of the rod of the actuator constituting the actuator 72 means 7 driving in rotation of the cleaning member 6 drive back and forth the rack 71 which itself rotates the pinion 73, and therefore the cleaning member 6. To complete the assembly, the device 1 comprises a sensor 16 for detecting the position of the cleaning enclosure 5 and the unit 18 for controlling the means 15 for driving the movement of the support 2 valve holder is configured to prevent the displacement of the support 2 valve holder in the close state of the enclosure 5 of the support 2 valve holder. This avoids a tearing of a valve which would protrude inside the enclosure 5. The sensor 16 for detecting the position of the cleaning enclosure 5 can be a presence or proximity sensor.
Le nettoyage d'une valve à l'aide d'un tel dispositif 1 s'opère donc comme suit : The cleaning of a valve using such a device 1 therefore takes place as follows:
Une valve 31 est, par entraînement en déplacement du support 2 porte- valves positionnée en regard du poste 2 de dosage, et ouverte par le mécanisme 17 de commande en ouverture/fermeture de valves pour déverser une partie du conteneur 30 fermé par la valve dans un récipient collecteur équipant le poste 14 de dosage. Ce poste 14 de dosage équipé du mécanisme 17 de commande en ouverture/fermeture de valves est monté mobile en monte et baisse pour venir en position haute coiffer, à l'aide du mécanisme de commande d'ouverture/fermeture de valves, une valve et permettre son ouverture. A valve 31 is, by driving the displacement of the support 2 valve holder positioned opposite the dosing station 2, and opened by the mechanism 17 for controlling the opening / closing of valves for discharging part of the container 30 closed by the valve in a collecting container equipping the dosing station 14. This dosing station 14 equipped with the mechanism 17 for opening / closing the valves is mounted movable up and down to come in the top position, using the valve opening / closing control mechanism, a valve and allow its opening.
Une fois la valve fermée et le poste 14 de dosage abaissé, le support 2 porte-valves est alors à nouveau déplacé pour amener la valve 31 venant d'être ouverte en regard de l'enceinte 5 du système 3 de nettoyage. Dans cette position de la valve 31 , l'enceinte 5 de nettoyage est entraînée en déplacement par le vérin 100 dans le sens d'un rapprochement du support 2 porte-valves jusqu'à une position dans laquelle la valve 31 fait saillie à l'intérieur de l'enceinte 5. Once the valve closed and the metering station 14 lowered, the support 2 valve holder is then moved again to bring the valve 31 just opened opposite the enclosure 5 of the cleaning system 3. In this position of the valve 31, the cleaning enclosure 5 is driven in displacement by the jack 100 in the direction of bringing the support closer together. 2 valve holders to a position in which the valve 31 projects inside the enclosure 5.
Dans cette position rapprochée de l'enceinte 5 du support 2 porte-valves, l'organe 6 de nettoyage est entraîné en déplacement par actionnement de l'actionneur 72 des moyens 7 d'entraînement en déplacement de l'organe 6 de nettoyage. In this position close to the enclosure 5 of the support 2 valve holder, the cleaning member 6 is driven in displacement by actuation of the actuator 72 of the means 7 for driving the cleaning member 6 in displacement.
Une fois le nettoyage achevé, l'enceinte 5 est écartée du support 2 porte- valves, et un nouveau dosage peut être effectué. Once the cleaning is complete, the enclosure 5 is moved away from the support 2 valve holders, and a new assay can be carried out.
Ainsi, il est possible après chaque ouverture d'une valve de procéder au nettoyage de cette dernière. Thus, it is possible after each opening of a valve to proceed to cleaning the latter.
