Description

L'invention a trait à un dispositif et à un procédé d'alimentation en produits de revêtement des projecteurs d'une installation de projection de produits de revêtement.The invention relates to a device and a method for supplying coating products for the projectors of a coating product projection installation.

Il est connu d'alimenter les projecteurs d'une installation de projection de produits de revêtement au moyen de conduits de circulation de produits, parfois dénommés "circulatings", à partir de réservoirs de grande quantité de produits dont la capacité peut atteindre plusieurs milliers de litres. Ces réservoirs sont généralement situés à distance des installations de projection dans un local communément dénommé "broirie". Compte tenu de la distance usuelle entre la broirie et l'installation de projection, les en-cours de produits présents dans les circulatings sont de l'ordre de plusieurs centaines de litres, ce qui rend économiquement impossible tout changement de produits dans de tels circulatings, les quantités de produits perdues à cette occasion étant rédhibitoires. Il convient donc de prévoir un circulating par teinte utilisée.It is known to supply the projectors of a coating product spraying installation by means of product circulation conduits, sometimes called "circulatings", from tanks of large quantity of products whose capacity can reach several thousands of products. liters. These tanks are generally located away from the projection facilities in a room commonly referred to as "burrow". Given the usual distance between the brewery and the projection plant, the work in progress of products in the circulatings are of the order of several hundred liters, which makes it economically impossible to change products in such circulatings , the quantities of products lost on this occasion being unacceptable. It is therefore necessary to provide a circulating per shade used.

Or, le nombre de teintes utilisées dans une installation de projection de produits de revêtement a tendance à augmenter, ce qui induit une augmentation du nombre de lignes de circulating et renchérit d'autant l'installation, alors que des problèmes d'encombrement se posent, notamment au niveau des traversées de cloisons.However, the number of shades used in a coating product projection installation tends to increase, which leads to an increase in the number of lines circulating and increases the installation of the same, while congestion problems arise. , especially at the level of the crossings of partitions.

L'utilisation de réservoirs embarqués sur le bras d'un robot multi-axes ne permet pas nécessairement de résoudre ce problème. En effet, dans le système connu de EP-A-0 274 322 , des circulatings de produits de revêtement sont prévus jusque dans la zone d'activité du robot. Dans d'autres systèmes, tels que connus par exemple de EP-A-0 796 665 , un carrousel est prévu pour le remplissage de cartouches de produits de revêtement mais des circulatings d'alimentation en produits de revêtement sont prévus jusqu'au voisinage de ce carrousel pour le remplissage des cartouches.The use of tanks on the arm of a multi-axis robot does not necessarily solve this problem. Indeed, in the known system of EP-A-0 274 322 Circulation of coating products are provided up to the area of activity of the robot. In other systems, as known for example from EP-A-0 796 665 a carousel is provided for the filling of coating product cartridges but coating material feed circulatings are provided up to the vicinity of this carousel for filling the cartridges.

Dans tous les cas, le brassage permanent des produits de revêtement dans les circulatings conduit à une dégradation de leurs propriétés physico-chimiques du fait des contraintes mécaniques auxquelles ils sont soumis, notamment du cisaillement subi au niveau des changements de direction, des pompes ou des régulateurs de pression.In all cases, the permanent mixing of the coating products in the circulatings leads to a degradation of their physicochemical properties because of the mechanical stresses to which they are subjected, in particular the shearing undergone at the level of the changes of direction, the pumps or the pressure regulators.

Une autre solution connue de DE-A-197 04 573 consiste à utiliser des cartouches prê-remplies, par exemple jetables, mais ceci conduit à des manipulations complexes d'un grand nombre de cartouches, ce qui n'est pas économiquement satisfaisant et complexifie grandement le système de gestion d'une telle installation.Another known solution of DE-A-197 04 573 is to use pre-filled cartridges, for example disposable, but this leads to complex handling of a large number of cartridges, which is not economically satisfactory and greatly complicates the management system of such an installation.

FR-A-2 777 482 enseigne de déplacer, sur une course limitée, un réservoir de produit utilisé rarement vers une unité de changement de produit de revêtement destinée à alimenter un unique réservoir porté par un robot. L'installation ainsi mise en oeuvre nécessite l'utilisation d'un carrousel à proximité de chaque robot et l'alimentation de chaque carrousel en réservoirs est une opération fastidieuse et longue. FR-A-2,777,482 teaches to move, on a limited stroke, a product tank rarely used to a coating product change unit for feeding a single tank carried by a robot. The installation thus implemented requires the use of a carousel near each robot and feeding each carousel tanks is a tedious and time consuming operation.

C'est à ces problèmes qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif d'alimentation de projecteur qui ne nécessite pas la construction d'un circulating jusqu'à proximité d'une installation et évite la manipulation d'un trop grand nombre de cartouches.It is these problems that the invention intends to remedy more particularly by proposing a new projector supply device which does not require the construction of a circulating device until close to an installation and avoids the manipulation of a too many cartridges.

Dans cet esprit, l'invention concerne un dispositif d'alimentation en produits de revêtement des projecteurs d'une installation sur des objets déplacés par un convoyeur, ce dispositif comprenant au moins un réservoir principal apte à alimenter successivement plusieurs réservoirs secondaires dédiés chacun à un projecteur et des moyens aptes à déplacer ce réservoir principal successivement jusqu'au voisinage, des réservoirs secondaires précités.With this in mind, the invention relates to a device for supplying products for coating the headlamps of an installation on objects moved by a conveyor, this device comprising at least one main reservoir capable of supplying successively several secondary reservoirs each dedicated to a projector and means adapted to move the main tank successively to the vicinity of the aforementioned secondary tanks.

Le ou les réservoirs principaux permettent d'alimenter différents réservoirs secondaires de l'installation en étant déplacés jusqu'à ces réservoirs. Les réservoirs principaux peuvent être conditionnés à l'extérieur de l'usine dans laquelle est mise en oeuvre l'installation et, notamment, dans les locaux du fabricant du produit de revêtement, les réservoirs principaux correspondant alors à un conditionnement particulier du produit. Il suffit alors de transporter différents réservoirs principaux jusqu'au voisinage de l'installation puis, en fonction du produit de revêtement à projeter, de déplacer un réservoir principal jusqu'aux différents réservoirs secondaires, afin de les alimenter en produits de revêtement. Aucune dégradation du produit de revêtement par cisaillement n'a lieu dans le ou les réservoirs principaux. Les réservoirs secondaires demeurent dans l'installation et il n'est pas nécessaire de gérer un grand nombre de cartouches jetables ou à re-remplir.The main tank (s) make it possible to feed various secondary tanks of the installation by being moved to these tanks. The main tanks may be conditioned outside the plant in which the installation is installed and, in particular, in the premises of the manufacturer of the coating product, the main tanks then corresponding to a particular packaging of the product. It then suffices to transport different main tanks to the vicinity of the installation and, depending on the coating product to be sprayed, to move a main tank to the various secondary tanks, to feed them coating products. No degradation of the product of shear coating takes place in the main reservoir (s). The secondary tanks remain in the facility and there is no need to manage a large number of disposable cartridges or refill.

Selon des aspects avantageux de l'invention, le dispositif incorpore une ou plusieurs des caractéristiques suivantes :

  • Le ou chaque réservoir principal est apte à contenir une quantité de produit de revêtement suffisante pour alimenter les réservoirs secondaires dédiés aux projecteurs de l'installation pour le revêtement complet d'un objet ou d'un côté d'objet. Ainsi, un réservoir principal peut, par exemple, permettre d'alimenter tous les projecteurs situés sur un côté de l'installation, avec une quantité de peinture adaptée et sans gaspillage. En variante, la quantité de produits présente dans le réservoir principal correspond au revêtement complet d'un objet.
  • Les moyens de déplacement précités comprennent au moins un convoyeur apte à déplacer les réservoirs principaux parallèlement à la direction d'avance d'un convoyeur de déplacement des objets.
  • Les moyens de déplacement des réservoirs principaux sont constitués par le convoyeur de déplacement des objets à revêtir.
According to advantageous aspects of the invention, the device incorporates one or more of the following features:
  • The or each main tank is capable of containing a quantity of coating material sufficient to supply the secondary tanks dedicated to the projectors of the installation for the complete coating of an object or an object side. Thus, for example, a main tank can be used to power all the projectors on one side of the installation, with a suitable amount of paint and without waste. Alternatively, the amount of products present in the main tank corresponds to the complete coating of an object.
  • The aforementioned displacement means comprise at least one conveyor capable of moving the main tanks parallel to the direction of advance of an object moving conveyor.
  • The means for moving the main tanks are constituted by the conveyor for moving the objects to be coated.

Selon un premier mode de réalisation avantageux de l'invention, les réservoirs principaux peuvent être raccordés à au moins un réservoir secondaire porté par un robot et associé à un projecteur.According to a first advantageous embodiment of the invention, the main tanks can be connected to at least one secondary tank carried by a robot and associated with a projector.

Selon un autre mode de réalisation de l'invention, le dispositif comprend au moins une station de stockage temporaire d'au moins un réservoir secondaire et des moyens de raccordement temporaire d'un réservoir principal avec au moins un réservoir secondaire en place dans cette station. Dans ce cas, les réservoirs secondaires peuvent être remplis en temps masqué dans la station de stockage temporaire.According to another embodiment of the invention, the device comprises at least one temporary storage station of at least one secondary tank and means for temporary connection of a main tank with at least one secondary tank in place in this station . In this case, the secondary tanks can be filled in masked time in the temporary storage station.

L'invention a également trait à un procédé qui peut être mis en oeuvre avec le dispositif précédemment décrit et, plus spécifiquement, à un procédé qui comprend des étapes consistant à :

  • acheminer au moins un réservoir principal contenant un produit de revêtement successivement jusqu'au voisinage du réservoir secondaire respectif des projecteurs ;
  • transvaser du produit de revêtement du réservoir principal vers le réservoir secondaire respectif et
  • alimenter au moins un des projecteurs en produits de revêtement à partir de son réservoir secondaire.
The invention also relates to a method which can be implemented with the previously described device and, more specifically, to a method which comprises steps of at :
  • conveying at least one main reservoir containing a coating product successively to the vicinity of the respective secondary reservoir of the projectors;
  • transferring coating material from the main tank to the respective secondary tank and
  • supplying at least one of the projectors with coating products from its secondary reservoir.

Selon un premier mode de réalisation avantageux de l'invention, le procédé comprend plus particulièrement des étapes consistant à :

  • acheminer le réservoir principal jusque dans la zone d'activité d'un robot de positionnement du projecteur et d'un réservoir secondaire dédié à ce projecteur ;
  • déplacer le réservoir secondaire au moyen du robot jusqu'au voisinage immédiat du réservoir principal avant de transvaser le produit du réservoir principal vers le réservoir secondaire et
  • après le transvasement, déplacer le réservoir secondaire vers une position dans laquelle le projecteur est apte à revêtir les objets précités.
According to a first advantageous embodiment of the invention, the method more particularly comprises the steps of:
  • route the main tank into the area of activity of a projector positioning robot and a secondary tank dedicated to this projector;
  • move the secondary tank by means of the robot to the immediate vicinity of the main tank before transferring the product from the main tank to the secondary tank and
  • after the transfer, move the secondary reservoir to a position in which the projector is able to coat the aforementioned objects.

Selon un autre mode de réalisation avantageux de l'invention, le procédé comprend des étapes consistant à :

  • acheminer le réservoir principal jusqu'au voisinage d'une station de stockage temporaire d'au moins un réservoir secondaire ;
  • transvaser du produit du réservoir principal vers au moins un réservoir secondaire en place dans la station et
  • monter au moins un réservoir secondaire rempli à partir dudit réservoir principal sur un robot d'application de peinture.
According to another advantageous embodiment of the invention, the method comprises the steps of:
  • conveying the main reservoir to the vicinity of a temporary storage station of at least one secondary reservoir;
  • transferring product from the main reservoir to at least one secondary reservoir in place in the station and
  • mounting at least one secondary reservoir filled from said main tank on a paint application robot.

Dans ce cas, l'on peut prévoir que chaque réservoir secondaire forme un sous-ensemble avec un projecteur auquel il est dédié et qu'on monte un tel sous-ensemble sur le robot après remplissage du réservoir secondaire dans l'unité de stockage temporaire.In this case, it can be provided that each secondary tank forms a subset with a projector to which it is dedicated and that such a subset is mounted on the robot after filling the secondary tank in the temporary storage unit .

Quel que soit le mode de réalisation considéré, le procédé consiste avantageusement à remplir le réservoir principal d'une quantité suffisante pour le revêtement d'un même objet ou d'un côté d'un même objet par différents projecteurs et à alimenter les projecteurs aux moyens de réservoirs secondaires remplis par transvasement à partir de ce réservoir principal.Whatever the embodiment considered, the method advantageously consists in filling the reservoir main amount of a sufficient amount for coating the same object or side of the same object by different projectors and to supply the projectors by means of secondary tanks filled by transferring from the main tank.

L'invention concerne enfin une installation de projection de produits de revêtement comprenant un dispositif tel que précédemment décrit, éventuellement mis en oeuvre grâce au procédé tel que précédemment décrit. Une telle installation est d'un prix de revient sensiblement inférieur aux installations connues devant être alimentées avec des circulatings et beaucoup plus simple à utiliser qu'une installation alimentée uniquement avec des cartouches dédiées chacune à un projecteur.Finally, the invention relates to a coating product projection installation comprising a device as previously described, optionally implemented by the method as previously described. Such an installation is a cost substantially lower than known installations to be powered with circulatings and much easier to use a facility powered only with cartridges each dedicated to a projector.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre de deux modes de réalisation d'une installation conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une représentation schématique de principe, en vue de dessus, d'une installation conforme à un premier mode de réalisation de l'invention, les projecteurs étant tous en cours d'application ;
  • la figure 2 est une coupe partielle, à plus grande échelle et selon la ligne II-II à la figure 1, d'une partie de l'installation de la figure 1 au cours du nettoyage/remplissage d'un réservoir d'un robot de cette installation ;
  • la figure 3 est une vue analogue à la figure 1 pour une installation conforme à un second mode de réalisation de l'invention et
  • la figure 4 est une coupe de principe selon la ligne IV-IV à la figure 3.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of two embodiments of an installation in accordance with its principle, given solely as an example and made with reference to the accompanying drawings in which:
  • the figure 1 is a schematic representation of principle, in top view, of an installation according to a first embodiment of the invention, the projectors are all being applied;
  • the figure 2 is a partial section, on a larger scale and along the line II-II to the figure 1 , part of the installation of the figure 1 during the cleaning / filling of a tank of a robot of this installation;
  • the figure 3 is a view similar to the figure 1 for an installation according to a second embodiment of the invention and
  • the figure 4 is a basic section along line IV-IV at figure 3 .

L'installation représentée à la figure 1 est prévue pour le revêtement en peinture liquide de carrosseries 1 de véhicule automobile déplacées par un convoyeur 2 selon une direction globalement rectiligne X-X'. Les carrosseries 1 sont chacune supportées par un chariot ou luge 3 entraîné par le convoyeur 2.The installation represented at figure 1 is provided for the liquid paint coating of motor vehicle bodies 1 moved by a conveyor 2 in a generally rectilinear direction X-X '. The bodies 1 are each supported by a trolley or sled 3 driven by the conveyor 2.

Des robots multi-axes 10 à 17 sont répartis, de part et d'autre du convoyeur 2 et des luges 3, et sont équipés chacun d'un projecteur 20 à 27 et d'un réservoir associé 30 à 37. Les réservoirs 30 à 37 sont montés à demeure à proximité du poignet de chaque robot. La contenance de chaque réservoir 30 à 37 est suffisante pour permettre l'application souhaitée de produits de revêtement sur une carrosserie 1.Multi-axis robots 10 to 17 are distributed, on either side of the conveyor 2 and the sleds 3, and are each equipped with a projector 20 to 27 and an associated reservoir 30 to 37. The tanks 30 to 37 are mounted permanently near the wrist of each robot. The capacity of each reservoir 30 to 37 is sufficient to allow the desired application of coating products on a bodywork 1.

On peut prévoir que les robots 10 à 13 sont dédiés à l'application d'une première couche de revêtement à l'intérieur d'une carrosserie alors que les robots 14 à 17 sont dédiés à l'application d'une seconde couche à l'intérieur de ces carrosseries. Selon une variante non représentée de l'invention, l'installation peut également comprendre d'autres robots dédiés respectivement à l'application d'une première couche et d'une seconde couche à l'extérieur de la carrosserie, un poste de retouches manuel étant éventuellement prévu dans la partie aval de la cabine de l'installation.It can be provided that the robots 10 to 13 are dedicated to the application of a first coating layer inside a body while the robots 14 to 17 are dedicated to the application of a second layer to the body. interior of these bodies. According to a variant not shown of the invention, the installation may also comprise other robots dedicated respectively to the application of a first layer and a second layer outside the body, a manual retouching station possibly being provided in the downstream part of the cabin of the installation.

Au terme du revêtement d'une carrosserie, chaque réservoir 30 à 37 doit être nettoyé et rempli avec un nouveau produit de revêtement, le plus souvent différent de celui utilisé précédemment car les véhicules automobiles sont peints en fonction des commandes des clients.At the end of the coating of a body, each tank 30 to 37 must be cleaned and filled with a new coating product, most often different from that used previously because motor vehicles are painted according to customer orders.

Pour ce faire, il est prévu, à proximité de chaque robot 10 à 17, des postes 40 à 47 de nettoyage des réservoirs. Le poste 40 est alimenté en air grâce à un conduit 40A, et en solvant grâce à un conduit 40S, alors qu'un conduit de purge 40P permet de collecter les résidus de peinture et de solvant résultant d'une opération de nettoyage. Les autres postes sont raccordés de la même façon à leur environnement.To do this, there is provided, near each robot 10 to 17, stations 40 to 47 for cleaning the tanks. The station 40 is supplied with air through a conduit 40A, and solvent through a conduit 40S, while a 40P bleed conduit to collect the paint and solvent residues resulting from a cleaning operation. The other stations are connected in the same way to their environment.

Au terme de l'utilisation du produit contenu dans le réservoir 30, le robot 10 approche le réservoir 30 et le projecteur 20 du poste 40, comme représenté par la flèche F1 à la figure 2. Une platine 40f du poste 40 est alors plaquée sur le pulvérisateur 20, cette platine étant pourvue de moyens de connexion 40e aptes à coopérer avec des moyens de connexion correspondants 20e prévus sur le projecteur 20. A l'intérieur du robot 10 sont prévus des conduits non représentés reliant le projecteur 20 au réservoir 30 et permettant d'alimenter, à partir des moyens 20e, le réservoir 30 en air et en solvant et d'en collecter les résidus.At the end of the use of the product contained in the reservoir 30, the robot 10 approaches the reservoir 30 and the projector 20 of the station 40, as represented by the arrow F 1 at the figure 2 . A plate 40 f of the station 40 is then pressed onto the sprayer 20, this plate being provided with connection means 40 e able to cooperate with corresponding connection means 20 e provided on the projector 20. Inside the robot 10 are planned unrepresented conduits connecting the projector 20 to the tank 30 and for supplying, from the means 20 e , the tank 30 with air and solvent and to collect the residues.

Ainsi, le poste 40 permet de nettoyer le projecteur 20 et le réservoir 30 avant une nouvelle utilisation.Thus, the station 40 makes it possible to clean the projector 20 and the tank 30 before a new use.

La situation est analogue pour les postes 41 à 47 et les autres projecteurs et réservoirs.The situation is similar for stations 41 to 47 and the other projectors and tanks.

Pour le remplissage des réservoirs 30, 32, 34 et 36, il est prévu de faire circuler des réservoirs principaux 50 sur un convoyeur 52 partant d'une zone de chargement 53 et arrivant à une zone de déchargement 54. Le convoyeur 52 comprend une branche 52a et une branche 52b globalement parallèles à la direction X-X', la circulation s'effectuant dans le sens d'avance du convoyeur sur la branche 52a et en sens inverse sur la branche 52b.For the filling of the tanks 30, 32, 34 and 36, it is intended to circulate the main tanks 50 on a conveyor 52 from a loading area 53 and arriving at an unloading area 54. The conveyor 52 comprises a branch 52 a and a branch 52 b generally parallel to the X-X 'direction, the traffic being effected in the forward direction of the conveyor on the branch 52 a and in the opposite direction on the branch 52 b .

Chaque réservoir principal 50 a une contenance égale à la somme des contenances des réservoirs 30, 32, 34 et 36 et est pourvu de moyens de connexion 50a prévus pour coopérer avec des moyens de connexion 30a disposés sur ou à proximité du réservoir 30.Each main tank 50 has a capacity equal to the sum of the capacities of the tanks 30, 32, 34 and 36 and is provided with 50 connecting means is provided to cooperate with the connection means 30 has disposed on or near the reservoir 30.

Les réservoirs 32, 34 et 36 sont également pourvus de tels moyens de connexion 32a, 34a et 36a.The tanks 32, 34 and 36 are also provided with such connecting means 32, 34a and 36 a.

Le fonctionnement est le suivant: Selon la teinte prévue pour une carrosserie pénétrant dans l'installation, un réservoir 50 est sélectionné et disposé, par un robot manipulateur non représenté, sur la zone de chargement à partir de laquelle il est acheminé par le convoyeur 52 jusqu'au niveau du robot 10. Au terme du revêtement de la carrosserie précédente, le robot 10 pivote pour venir accoster le poste de nettoyage 40 comme indiqué ci-dessus. La position du réservoir 50 est alors telle que le mouvement F1 du robot induit un accouplement des moyens 30a et 50a, ce qui permet de prélever dans le réservoir 50 la quantité prévue pour être stockée dans le réservoir 30 et appliquée par le projecteur 20 sur cette carrosserie.The operation is as follows: According to the hue provided for a body penetrating into the installation, a tank 50 is selected and arranged, by a manipulator robot not shown, on the loading area from which it is conveyed by the conveyor 52 to the level of the robot 10. At the end of the coating of the previous body, the robot 10 pivots to dock the cleaning station 40 as indicated above. The position of the container 50 is then such that movement F 1 of the robot induces a coupling means 30 a and 50 a, which allows to collect in the tank 50 the amount intended to be stored in the reservoir 30 and applied by the headlamp 20 on this body.

Au vu de ce qui précède, le nettoyage du projecteur 20 et du réservoir 30 et le remplissage du réservoir 30 ont lieu grâce à un unique mouvement du robot 10. En d'autres termes, la position de nettoyage du projecteur et du réservoir est la même que la position de remplissage du réservoir.In view of the foregoing, the cleaning of the projector 20 and the tank 30 and the filling of the tank 30 take place by a single movement of the robot 10. In other words, the cleaning position of the projector and tank is the same as the filling position of the tank.

Comme le robot 10 est accosté sur la station 40 lors du remplissage du réservoir 30 à partir du réservoir 50, il est possible d'alimenter le réservoir 50 en air de pressurisation à partir du poste 40 et à travers le robot 10. Ainsi, le transvasement de produits du réservoir 50 vers le réservoir 30 peut avoir lieu sous pression, ce qui permet de diminuer le temps de cycle.As the robot 10 is docked on the station 40 during the filling of the tank 30 from the tank 50, it is possible to supply the tank 50 with pressurizing air from the station 40 and through the robot 10. Thus, the transferring of products from the tank 50 to the tank 30 can take place under pressure, which makes it possible to reduce the cycle time.

L'alimentation en air 40A du poste 40 peut également être utilisée pour actionner des moyens d'agitation prévus dans le réservoir 50, afin d'homogénéiser le produit avant son transfert vers le réservoir 30.The air supply 40A of the station 40 can also be used to actuate the stirring means provided in the tank 50, in order to homogenize the product before it is transferred to the tank 30.

Pendant ce nettoyage et ce remplissage, la carrosserie 1 en question progresse en direction du robot 10 et, au terme de l'opération de remplissage du réservoir 30, l'application avec le projecteur 20 peut débuter.During this cleaning and filling, the body 1 in question progresses towards the robot 10 and, at the end of the filling operation of the reservoir 30, the application with the projector 20 can begin.

Le convoyeur 52 déplace alors le réservoir principal 50 en direction du robot 12 au niveau duquel le réservoir 32 est nettoyé et rempli comme le réservoir 30 en vue de l'application du même produit sur la même carrosserie.The conveyor 52 then moves the main tank 50 towards the robot 12 at which the tank 32 is cleaned and filled as the tank 30 for the application of the same product on the same body.

Le réservoir 50 poursuit alors sa progression en direction des robots 14 et 16 en vue du nettoyage et du remplissage successifs des réservoirs 34 et 36.The tank 50 then continues its progress towards the robots 14 and 16 for the successive cleaning and filling tanks 34 and 36.

Après le dernier robot, le réservoir 50 est acheminé en direction de la zone de déchargement 54 par un retour le long de la branche 52b du convoyeur 52.After the last robot, the tank 50 is conveyed towards the discharge zone 54 by a return along branch 52 b of the conveyor 52.

La situation est analogue en ce qui concerne le côté opposé des carrosseries 1 où un convoyeur 52' est prévu, entre une zone de chargement 53' et une zone de déchargement 54', pour l'acheminement de réservoirs principaux 50' jusqu'au niveau des robots 11, 13, 15 et 17 en vue du remplissage des réservoirs 31, 33, 35 et 37.The situation is similar with regard to the opposite side of the bodies 1 where a conveyor 52 'is provided, between a loading zone 53' and an unloading zone 54 ', for conveying main tanks 50' up to the level robots 11, 13, 15 and 17 for filling reservoirs 31, 33, 35 and 37.

Si d'autres robots sont prévus en aval des robots 16 et 17, la capacité des réservoirs 50 et 50' est augmentée. Dans tous les cas, les réservoirs 50 et 50' transportent une quantité de peinture suffisante pour le revêtement complet d'un côté d'une carrosserie 1. En pratique, on peut envisager de remplir les réservoirs 50 et 50' d'une quantité légèrement supérieure aux besoins théoriques pour disposer d'une réserve, par exemple en vue d'une application manuelle.If other robots are provided downstream of the robots 16 and 17, the capacity of the tanks 50 and 50 'is increased. In any case, the tanks 50 and 50 'carry a sufficient quantity of paint for the complete coating on one side of a bodywork 1. In practice, it is possible to envisage fill the tanks 50 and 50 'with a quantity slightly greater than the theoretical requirements to have a reserve, for example for manual application.

Dans le cas où un poste d'application manuelle est prévu, les réservoirs 50 et 50' sont acheminés jusqu'à ce poste. Les pistolets des peintres sont équipés de réservoirs embarqués qui peuvent être remplis à partir des réservoirs principaux. Selon une variante avantageuse, les pistolets manuels peuvent être dépourvus de réservoirs embarqués, les pistolets étant directement alimentés par les réservoirs principaux 50 et 50' au moyen de tuyaux souples. Dans ce cas, un moyen de pressurisation du volume intérieur des réservoirs principaux peut être prévu.In the case where a manual application station is provided, the tanks 50 and 50 'are conveyed to this station. Painters' guns are equipped with on-board tanks that can be filled from the main tanks. According to an advantageous variant, the manual guns may be devoid of on-board tanks, the guns being directly supplied by the main tanks 50 and 50 'by means of flexible hoses. In this case, a means of pressurizing the interior volume of the main tanks can be provided.

Des râteliers 55 et 55' sont disposés à proximité des zones de chargement 53 et 53' pour l'approvisionnement des convoyeurs 52 et 52' en réservoirs principaux 50 et 50', en fonction des teintes sélectionnées pour les carrosseries 1. Ces râteliers peuvent être préparés à l'extérieur de l'atelier de projection de peinture, la répartition des teintes dans les différents réservoirs 50 et 50' étant prédéterminée en fonction de l'utilisation prévue de l'installation.Racks 55 and 55 'are arranged near the loading areas 53 and 53' for the supply of the conveyors 52 and 52 'in the main tanks 50 and 50', depending on the colors selected for the bodies 1. These racks can be prepared outside the paint spraying workshop, the distribution of colors in the different tanks 50 and 50 'being predetermined depending on the intended use of the installation.

Dans le cas de produits de revêtement bi-composant, on peut prévoir que la base des produits est transportée grâce aux réservoirs principaux 50 et 50' alors que le catalyseur, qui est identique quelle que soit la base considérée, est amené par un conduit 40K, représenté uniquement à la figure 2, au niveau du poste 40. Ainsi, lors du remplissage du réservoir 30 en base à partir du réservoir 50, un remplissage en catalyseur peut avoir lieu à partir du poste 40.In the case of two-component coating products, it is expected that the product base is transported through the main tanks 50 and 50 'while the catalyst, which is identical regardless of the base considered, is brought by a 40K conduit , represented only in figure 2 at the station 40. Thus, when the base tank 30 is filled from the tank 50, a catalyst filling can take place from the station 40.

En variante, le conduit 40K d'alimentation en catalyseur peut être disposé dans le bras de chaque robot, comme représenté en traits mixtes pour le robot 10 à la figure 2.Alternatively, the catalyst supply conduit 40K may be disposed in the arm of each robot, as shown in phantom for robot 10 at the figure 2 .

Dans tous les cas, le mélange entre la base et le catalyseur a lieu juste avant l'utilisation du produit contenu dans le réservoir 30.In all cases, the mixture between the base and the catalyst takes place just before the use of the product contained in the tank 30.

Dans le second mode de réalisation de l'invention représenté aux figures 2 et 3, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 100. Dans ce mode de réalisation, des carrosseries 101 sont transportées par des luges 103 déplacées par un convoyeur 102. Des robots 110 à 117 sont disposés de part et d'autre de ce convoyeur et sont équipés de sous-ensembles 160 à 167 comprenant chacun un projecteur 120 à 127 et un réservoir 130 à 137, chaque sous-ensemble étant monté de façon amovible à l'extrémité du bras d'un robot. Comme précédemment, des réservoirs principaux 150 et 150' sont acheminés par des convoyeurs 152 et 152' le long du convoyeur 102.In the second embodiment of the invention shown in figures 2 and 3 elements similar to those of the first embodiment bear references In this embodiment, bodies 101 are transported by sleds 103 moved by a conveyor 102. Robots 110 to 117 are disposed on either side of this conveyor and are equipped with subassemblies 160. to 167 each comprising a projector 120 to 127 and a reservoir 130 to 137, each subassembly being removably mounted at the end of the arm of a robot. As before, main tanks 150 and 150 'are conveyed by conveyors 152 and 152' along the conveyor 102.

Entre les robots 110 et 112 est installée une station 140 de stockage temporaire de sous-ensembles 160 et équivalents, cette station 140 étant destinée à la préparation de sous-ensembles prévus pour être montés sur les robots 110 et 112.Between the robots 110 and 112 is installed a station 140 for temporary storage of subsets 160 and the like, this station 140 being intended for the preparation of subassemblies intended to be mounted on the robots 110 and 112.

Comme il ressort plus particulièrement de la figure 4, la station 140 délimite quatre logements 140a, 140b, 140c et 140d de réception de sous-ensembles 160 et 162. Plus précisément, les logements 140a et 140b sont dédiés à la réception de sous-ensembles à monter sur le robot 110 alors que les logements 140c et 140d sont dédiés aux sous-ensembles à monter sur le robot 112. Le logement 140a contient effectivement un sous-ensemble 160' alors que le logement 140b est prêt à recevoir le sous-ensemble 160 monté à l'extrémité du robot 110. De la même façon, le logement 140c contient un sous-ensemble 162' destiné à être monté sur le robot 112 alors que le logement 140d est vide et prêt à recevoir le sous-ensemble 162 monté sur le robot 112. Les sous-ensembles 160' et 162' comprennent respectivement des projecteurs 120' et 122' et des réservoirs 130' et 132' analogues à ceux des sous-ensembles 160 et 162.As is clear from the figure 4 , The station 140 defines four slots 140 a, 140 b, 140 c and 140d receiving subassemblies 160 and 162. Specifically, housing 140 a and 140 b are dedicated to the reception of subassemblies to be mounted on the robot 110 while the housing 140 c and 140 d are dedicated to the subassemblies to be mounted on the robot 112. the housing 140 actually contains a subset 160 'while the housing 140 b is ready for the subset 160 mounted at the end of the robot 110. Similarly, housing 140 c contains a subset 162 'intended to be mounted on the robot 112 while the housing 140d is empty and ready to receive the subset 162 mounted on the robot 112. The subassemblies 160 'and 162' respectively comprise projectors 120 'and 122' and reservoirs 130 'and 132' similar to those of the subassemblies 160 and 162.

La station 140 est équipée d'un conduit 140A d'alimentation en air, d'un conduit 140S d'alimentation en solvant et d'un conduit de purge 140p.The station 140 is equipped with an air supply duct 140A, a solvent supply duct 140S and a 140 p drain duct.

Au vu de ce qui précède, on comprend que les robots 110 et 112 prennent alternativement l'un des sous-ensembles 160 ou 162 disponible dans la station 140, le remplissage d'un sous-ensemble pouvant avoir lieu pendant que l'autre sous-ensemble est en cours d'utilisation sur l'un des robots.In view of the above, it is understood that the robots 110 and 112 take alternately one of the subsets 160 or 162 available in the station 140, the filling of a subset can take place while the other under -All is in use on one of the robots.

Ce remplissage a lieu grâce au réservoir 150 qui est amené par le convoyeur 152 jusqu'au niveau de la station 140, le réservoir 150 étant pourvu d'un moyen 150a de connexion rapide avec des moyens de connexion 140e portés par une platine 140f susceptible de mouvements de translation, représentés par la double flèche F2 à la figure 4, en étant commandée par un vérin 140g qui peut être hydraulique, pneumatique ou électrique.This filling takes place through the reservoir 150 which is brought by the conveyor 152 up to the level of the station 140, the reservoir 150 being provided with a means 150 has rapid connection means for connecting 140th carried by a plate 140 f capable of translational movements, represented by the double arrow F 2 at the figure 4 , being controlled by a cylinder 140g which can be hydraulic, pneumatic or electric.

Les moyens de connexion 140e sont reliés par des tuyaux souples non représentés aux sous-ensembles 160 et 162 présents dans les logements 140a à 140d.The 140th connection means are connected by flexible pipes not shown in the subsets 160 and 162 present in housing 140 a to 140 d.

Il est possible de remplir les réservoirs 130 et 132 des sous-ensembles 160 et 162 lorsque ils sont en place dans la station 140 et avant que les robots 110 et 112 ne viennent prendre en charge ces sous-ensembles en vue de la projection des produits de revêtement sur les carrosseries 101.It is possible to fill the tanks 130 and 132 of the subassemblies 160 and 162 when they are in place in the station 140 and before the robots 110 and 112 come to take charge of these subassemblies for the projection of the products. coating on the bodies 101.

Le réservoir 150 peut être alimenté en air de pressurisation ou en air d'actionnement d'un agitateur à partir du conduit 140A du poste 140 lorsque la platine 140f est au contact du réservoir 150, des moyens de raccordement appropriés étant alors prévus.The reservoir 150 can be supplied with pressurizing air or with air for actuating an agitator from the conduit 140A of the station 140 when the plate 140 f is in contact with the reservoir 150, appropriate connection means being then provided.

Une autre station 141, analogue à la station 140, est prévue entre les robots 114 et 116 pour la préparation des sous-ensembles 164 et 166, tout particulièrement pour le nettoyage des projecteurs 124 et 136 et le nettoyage/remplissage des réservoirs 134 et 136.

Selon un aspect avantageux de l'invention, les stations 140, 140', 141 et 141' sont prévues à l'intérieur d'une cabine de projection, alors que les convoyeurs 152 et 152' sont disposés à l'extérieur de cette cabine, par exemple à un étage différent. Dans ce cas, le remplissage des réservoirs 130 à 137 a lieu par une traversée de cloison de cette cabine. Selon une variante, les stations 140, 140', 141 et 141' peuvent être disposées à l'extérieur de la cabine où elles sont alimentées en produits de revêtement, ces stations étant, en partie au moins, mobiles pour amener les sous-ensembles 120 à 127 à l'intérieur de la cabine en traversant une cloison de celle-ci, afin que les robots 110 à 117 puissent accéder aux logements 140a à 140d et équivalents.According to an advantageous aspect of the invention, the stations 140, 140 ', 141 and 141' are provided inside a projection booth, while the conveyors 152 and 152 'are arranged outside this booth , for example on a different floor. In this case, the filling of the tanks 130 to 137 takes place by a partition passage of this cabin. According to one variant, the stations 140, 140 ', 141 and 141' can be arranged outside the cabin where they are fed with coating products, these stations being, at least in part, movable to bring the sub-assemblies together. 120 to 127 inside the cabin through a wall thereof, so that the crawler 110 to 117 have access to the housing 140 a to 140 d and the like.

Selon une variante non représentée de l'invention, une station de stockage temporaire de réservoir peut être associée à chaque robot 110 à 117, chaque station comprenant deux logements de réception de deux sous-ensembles montés alternativement sur chaque robot. Le mode de réalisation représente le regroupement des stations pour deux robots, avec quatre emplacements de réception de sous-ensembles, permet un gain de place et un prix de revient plus attractif. Quel que soit le mode de réalisation considéré, des moyens de contrôle de la température du produit dans les réservoirs principaux peuvent être prévus, ces moyens pouvant être activés en permanence ou juste avant le transvasement vers les réservoirs secondaires. De même, des moyens d'agitation peuvent être activés en permanence ou juste avant le transvasement.According to a variant not shown of the invention, a temporary tank storage station may be associated with each robot 110 to 117, each station comprising two receiving housing of two subassemblies mounted alternately on each robot. The embodiment represents the grouping of the stations for two robots, with four subassembly receiving locations, allows space saving and a more attractive cost price. Whatever the embodiment considered, means for controlling the temperature of the product in the main tanks can be provided, these means can be activated permanently or just before the transfer to the secondary tanks. Similarly, stirring means can be activated permanently or just before the transfer.

Selon une variante non représentée de l'invention applicable aux deux modes de réalisation décrits, les convoyeurs de déplacement des réservoirs principaux peuvent être constitués par le convoyeur 2 ou 102, dans la mesure où les réservoirs principaux peuvent être supportés par les luges 3 ou 103, le mouvement de connexion des robots ou des parties des stations de stockage temporaire étant adapté en conséquence.According to a not shown variant of the invention applicable to the two embodiments described, the displacement conveyors of the main tanks may be constituted by the conveyor 2 or 102, insofar as the main tanks may be supported by the sleds 3 or 103, the connection movement of the robots or parts of the temporary storage stations being adapted in result.

L'invention a été décrite avec une installation de projection de produits de revêtement liquide. Elle est applicable à la projection de tous types de produits liquides solvantés, hydrosolubles ou bi-composant et à la projection de produits de revêtement pulvérulents.The invention has been described with a projection installation of liquid coating products. It is applicable to the projection of all types of solvent-based, water-soluble or two-component liquid products and to the projection of powder coating products.

L'invention a été représentée dans le cas d'une installation de revêtement de carrosseries de véhicules automobiles. Elle est cependant applicable au revêtement de tous types d'objets, notamment de pièces détachées, au moyen de projecteurs de tous types, électrostatiques ou non, rotatifs ou pneumatiques.The invention has been shown in the case of a coating plant for motor vehicle bodies. However, it is applicable to the coating of all types of objects, including spare parts, by means of projectors of all types, electrostatic or not, rotary or pneumatic.

L'invention a été représentée avec des robots multi-axes. Elle est applicable avec tout type de robot apte à déplacer au moins un pulvérisateur en regard d'objets à revêtir, notamment avec les machines de type "réciprocateur" ou du type connu de EP 0 720 515 . L'invention pourrait également être mise en oeuvre avec une installation comprenant une succession de postes de revêtement manuels.The invention has been represented with multi-axis robots. It is applicable with any type of robot capable of moving at least one sprayer facing objects to be coated, especially with the type of "reciprocating" machines or the known type of EP 0 720 515 . The invention could also be implemented with an installation comprising a succession of manual coating stations.

Dans le cas d'une installation existante comprenant déjà des circulatings ou dans le cas d'une installation prévue pour la projection de produits dits "courants" et de produits dits "rares" utilisés moins souvent, des circulatings peuvent être employés pour alimenter les projecteurs avec les produits les plus souvent employés alors que le dispositif avec réservoirs principaux est utilisé pour les produits les moins souvent employés.In the case of an existing installation already comprising circulatings or in the case of an installation intended for the projection of products known as "current" and of so-called "rare" products used less often, circulatings can be used to supply the projectors with the most frequently used products while the device with main tanks is used for the least frequently used products.

Quelle que soit la variante considérée, un ou plusieurs projecteurs montés sur un robot ou une machine peuvent être alimentés à partir d'un même réservoir secondaire.Whatever the variant considered, one or more projectors mounted on a robot or a machine can be powered from the same secondary tank.

Selon une variante non représentée de l'invention, les zones 53 et 54 de chargement/déchargement des réservoirs principaux peuvent être prévues à deux extrémités opposées de la cabine, ce qui évite d'avoir recours à un convoyeur 52 en boucle. Ceci vaut également pour le second mode de réalisation. According to a not shown variant of the invention, the zones 53 and 54 for loading / unloading the main tanks can be provided at two opposite ends of the the cabin, which avoids using a conveyor 52 loop. This also applies to the second embodiment.
