Description

La présente invention concerne une unité d'alimentation d'une station de poudrage en produit de revêtement pulvérulent.The present invention relates to a unit for supplying a powder coating station with powder coating product.

Le domaine technique de l'invention est celui des stations ou installations de poudrage, dans lesquelles un ou plusieurs pulvérisateurs projettent un produit de revêtement en poudre sur des objets à revêtir. Ce ou ces pulvérisateurs peuvent être manuels ou automatiques, auquel cas ils sont avantageusement déplacés par un robot du type multiaxe ou réciprocateur.The technical field of the invention is that of powder coating stations or installations, in which one or more sprayers project a powder coating product onto objects to be coated. This or these sprayers can be manual or automatic, in which case they are advantageously moved by a robot of the multi-axis or reciprocating type.

Dans ce genre de station, il est connu de prévoir une unité ou centrale d'alimentation de la station de poudrage, plus particulièrement de son ou ses pulvérisateurs, avec un produit de revêtement pulvérulent. Une telle unité comprend généralement une carcasse ou enveloppe, installée au voisinage d'une cabine de revêtement et qui définit un volume interne dans lequel est disposé un réservoir de produit de revêtement fluidisé. Ce réservoir de produit de revêtement fluidisé est alimenté par une pompe qui aspire le produit de revêtement pulvérulent dans un contenant déposé sur un support, par exemple une table vibrante.In this type of station, it is known to provide a unit or central unit for supplying the powder coating station, more particularly its sprayer(s), with a powder coating product. Such a unit generally comprises a carcass or casing, installed in the vicinity of a coating booth and which defines an internal volume in which a reservoir of fluidized coating product is arranged. This reservoir of fluidized coating product is supplied by a pump which sucks the powder coating product into a container placed on a support, for example a vibrating table.

Des unités d'alimentation de l'art antérieur sont connues de US2019/314836A1 , US7074274B1 , US7325750B2 et US 2007/235558 A1 .Prior art power supply units are known from US2019/314836A1 , US7074274B1 , US7325750B2 And US 2007/235558 A1 .

Le produit de revêtement pulvérulent est souvent disponible en étant emballé dans un carton ou un sac dont la masse est de l'ordre de 20 kilogrammes (kg), voire plus. Au cours d'une journée de travail, plusieurs contenants pleins de poudre doivent être successivement chargés sur le support, dans un espace exigu, à proximité du réservoir de produit de revêtement fluidisé, dans le volume interne de la carcasse. Lorsqu'un contenant a été totalement ou partiellement vidé, il doit être déchargé du support et évacué hors de cet espace exigu, pour permettre la mise en place d'un autre contenant, par exemple en cas de changement de couleur du produit de revêtement à projeter. En fonction de la consommation de la station de poudrage en produit de revêtement, des opérations de chargement/déchargement de contenants de produit de revêtement sur le support peuvent avoir lieu jusqu'à dix fois sur un poste de huit heures. Ces opérations ont lieu dans un espace exigu, ce qui est de nature à entrainer une fatigue accrue et des troubles musculo-squelettiques pour un opérateur.The powder coating product is often available packaged in a cardboard box or bag weighing around 20 kilograms (kg) or more. During a working day, several full containers of powder must be successively loaded onto the support, in a confined space, near the fluidized coating product reservoir, in the internal volume of the carcass. When a container has been completely or partially emptied, it must be unloaded from the support and removed from this confined space, to allow the installation of another container, for example in the event of a change in the color of the coating product to be sprayed. Depending on the coating product consumption of the powder coating station, loading/unloading operations of coating product containers onto the support may take place up to ten times during an eight-hour shift. These operations take place in a confined space, which is likely to cause increased fatigue and musculoskeletal disorders for an operator.

C'est à ces problèmes qu'entend plus particulièrement remédier l'invention en proposant une nouvelle unité d'alimentation d'une station de poudrage dont le chargement en produit de revêtement pulvérulent est facilité.It is these problems that the invention more specifically intends to remedy by proposing a new supply unit for a powder coating station, the loading of which with powder coating product is facilitated.

À cet effet, l'invention concerne une unité d'alimentation d'une station de poudrage en produit de revêtement pulvérulent, cette unité d'alimentation comprenant un réservoir de produit de revêtement fluidisé, un support de réception d'un contenant de produit de revêtement, une pompe d'alimentation du réservoir de produit de revêtement fluidisé à partir du contenant porté par le support et une carcasse qui définit un volume interne de réception du réservoir de produit de revêtement fluidisé et qui est pourvue d'une ouverture d'accès à ce volume interne. Conformément à l'invention, le support est mobile en rotation ou en translation circulaire autour d'au moins un axe, dans les deux sens, au moins entre

  • une première position de chargement/déchargement, dans laquelle le support dépasse à l'extérieur du volume interne de la carcasse, à travers l'ouverture d'accès ; et
  • une deuxième position de transfert de produit de revêtement, dans laquelle le support et un contenant en place sur le support sont inclus dans le volume interne de la carcasse.
To this end, the invention relates to a unit for supplying a powder coating station with powder coating product, this supply unit comprising a reservoir of fluidized coating product, a support for receiving a container of coating product, a pump for supplying the reservoir of fluidized coating product from the container carried by the support and a carcass which defines an internal volume for receiving the reservoir of fluidized coating product and which is provided with an opening for access to this internal volume. According to the invention, the support is movable in rotation or in circular translation around at least one axis, in both directions, at least between
  • a first loading/unloading position, in which the support protrudes outside the internal volume of the carcass, through the access opening; and
  • a second coating product transfer position, in which the support and a container in place on the support are included in the internal volume of the carcass.

Grâce à l'invention, la mise en rotation ou la translation circulaire du support permet d'amener celui-ci dans sa première position, dans laquelle il est aisément accessible pour un opérateur puisqu'il dépasse à l'extérieur de la carcasse, ce qui facilite le chargement du support avec le contenant rempli en produit de revêtement pulvérulent. Ceci évite à l'opérateur de devoir porter le contenant de produit de revêtement jusqu'à l'intérieur de l'unité d'alimentation. Ceci permet de limiter fortement la fatigue et d'éviter les troubles musculo-squelettiques de l'opérateur. Les mêmes avantages sont induits lorsqu'il convient de décharger un contenant à partir du support, ce contenant pouvant être vide ou partiellement rempli de produit de revêtement pulvérulent, notamment en cas de changement de couleur. Dans la deuxième position, le support et le contenant en place sur ce support sont correctement disposés, dans le volume interne de la carcasse, pour que la pompe puisse aspirer le produit de revêtement dans le contenant. Comme le support et le contenant sont inclus dans le volume interne de la carcasse, ils ne gênent pas le passage des opérateurs ou de chariots de transport à proximité de l'unité d'alimentation, ce qui améliore la sécurité de la station de poudrage. La rotation ou la translation circulaire mise en oeuvre pour le déplacement du support entre ses deux positions présente l'avantage d'être un mouvement simple, bien maîtrisé, qui n'induit pas d'encombrement de l'espace à l'extérieur de la carcasse.By virtue of the invention, the rotation or circular translation of the support allows it to be brought into its first position, in which it is easily accessible for an operator since it protrudes outside the carcass, which facilitates the loading of the support with the container filled with powder coating product. This avoids the operator having to carry the container of coating product to the inside of the supply unit. This makes it possible to greatly limit fatigue and avoid musculoskeletal disorders for the operator. The same advantages are induced when it is necessary to unload a container from the support, this container being able to be empty or partially filled with powder coating product, in particular in the event of a change of color. In the second position, the support and the container in place on this support are correctly arranged, in the internal volume of the carcass, so that the pump can suck the coating product into the container. As the support and the container are included in the internal volume of the carcass, they do not hinder the passage of operators or transport trolleys near the supply unit, which improves the safety of the powder coating station. The rotation or circular translation implemented to move the support between its two positions has the advantage of being a simple, well-controlled movement, which does not cause any clutter in the space outside the carcass.

Selon des aspects avantageux mais non obligatoires de l'invention, une telle unité d'alimentation peut incorporer une ou plusieurs des caractéristiques suivantes prise(s) selon toute combinaison techniquement admissible :

  • L'axe de rotation est vertical et, de préférence, disposé, en partie, dans le volume interne de la carcasse.

Selon un deuxième aspect, l'invention concerne une station de poudrage qui comprend au moins un pulvérisateur de produit de revêtement pulvérulent installé dans une cabine de revêtement et alimenté en produit de revêtement par une unité d'alimentation telle que mentionnée ci-dessus.According to a second aspect, the invention relates to a powder coating station which comprises at least one powder coating product sprayer installed in a coating booth and supplied with coating product by a supply unit as mentioned above.

Une telle station de poudrage induit les mêmes avantages que ceux mentionnés ci-dessus au sujet de l'unité d'alimentation, en particulier en termes de diminution des troubles musculo-squelettiques pour l'opérateur et de sécurité.Such a powder coating station induces the same advantages as those mentioned above regarding the supply unit, in particular in terms of reduction of musculoskeletal disorders for the operator and safety.

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

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 a supply unit and a powdering station in accordance with its principle, given solely as an example and made with reference to the attached drawings in which:
  • [ Fig. 1 ] There figure 1 is a schematic perspective representation of a powder coating station and a supply unit according to a first embodiment of the invention;

  • [ Fig.8 ] There figure 8 is a view analogous to the figure 4 , for the second embodiment.

La figure 1 représente une station ou installation de poudrage 2 qui comprend une cabine de revêtement 4 dans laquelle des objets non représentés sont déplacés selon un axe de convoyage A4, par un convoyeur, également non représenté, dont les balancelles traversent une fente longitudinale 42 ménagée dans le plafond 44 de la cabine 4. La cabine 4 contient un ou plusieurs pulvérisateurs 6 dont un seul est représenté, de façon très schématique, à la figure 1 et qui est orienté vers les objets déplacés par le convoyeur, à l'intérieur de la cabine 4.There figure 1 represents a powder coating station or installation 2 which comprises a coating booth 4 in which objects, not shown, are moved along a conveyor axis A4, by a conveyor, also not shown, whose swings pass through a longitudinal slot 42 made in the ceiling 44 of the booth 4. The booth 4 contains one or more sprayers 6, only one of which is shown, very schematically, at the figure 1 and which is oriented towards the objects moved by the conveyor, inside cabin 4.

Dans l'exemple des figures, le pulvérisateur 6 est un pulvérisateur automatique déplacé par un robot multiaxe non représenté, selon les trois axes X, Y, Z d'un repère orthogonal XYZ, l'axe X étant parallèle à l'axe de convoyage A4. En variante, le robot est de type réciprocateur ou d'un autre type et le déplacement du pulvérisateur 6 a eu lieu selon certains ou tous les axes X, Y, Z. Selon une autre variante, le pulvérisateur 6 est un pulvérisateur manuel porté par un peintre qui se tient dans la cabine 4.In the example of the figures, the sprayer 6 is an automatic sprayer moved by a multi-axis robot not shown, along the three axes X, Y, Z of an orthogonal reference frame XYZ, the X axis being parallel to the conveying axis A4. Alternatively, the robot is of the reciprocating type or of another type and the movement of the sprayer 6 took place along some or all of the axes X, Y, Z. According to another alternative, the sprayer 6 is a manual sprayer carried by a painter who stands in the booth 4.

Le pulvérisateur 6 peut être de type électrostatique ou triboélectrique.The sprayer 6 can be of the electrostatic or triboelectric type.

Le nombre de pulvérisateur 6 de la cabine 4 est adapté à son volume et à la taille des pièces à revêtir.The number of sprayers 6 in cabin 4 is adapted to its volume and the size of the parts to be coated.

La station de poudrage 2 comprend également une unité d'alimentation 10 qui sert à fournir chaque pulvérisateur 6 avec un mélange d'air et de produit de revêtement pulvérulent, à partir d'un réservoir 102 disposé dans le volume interne V104 d'une carcasse 104 qui constitue l'enveloppe extérieure de l'unité d'alimentation 10 et qui, dans l'exemple des figures est parallélépipédique et accolée à la cabine de revêtement 4.The powder coating station 2 also comprises a supply unit 10 which serves to supply each sprayer 6 with a mixture of air and powder coating product, from a reservoir 102 arranged in the internal volume V104 of a carcass 104 which constitutes the outer casing of the supply unit 10 and which, in the example of the figures, is parallelepipedal and attached to the coating booth 4.

L'unité 10 peut également être dénommée centrale de poudrage.Unit 10 may also be referred to as the powder coating plant.

Une équerre 103 supporte le réservoir 102 dans le volume interne V104, dans une position fixe par rapport à la carcasse 104. Le réservoir 102 est ainsi relativement isolé de l'environnement extérieur de la station de poudrage 2 et protégé mécaniquement contre les chocs.A bracket 103 supports the tank 102 in the internal volume V104, in a fixed position relative to the carcass 104. The tank 102 is thus relatively isolated from the external environment of the powdering station 2 and mechanically protected against shocks.

La carcasse 104 a également pour fonction de limiter la diffusion de grains de poudre hors de la station d'alimentation 10.The carcass 104 also has the function of limiting the diffusion of powder grains out of the feeding station 10.

Un conduit d'alimentation 106 relie le réservoir 102 à chaque pulvérisateur 6.A supply conduit 106 connects the reservoir 102 to each sprayer 6.

Comme visible aux figures 2 à 4, une platine de connexion 108 est fixée sur une paroi de fond 110 de la carcasse 104 et une première partie 106A du conduit 106 s'étend entre le réservoir 102 et la platine 108, dans le volume interne V104, alors qu'une deuxième partie 106B de ce conduit s'étend entre la platine et le pulvérisateur 6, à l'extérieur du volume interne V104.As visible to the figures 2 to 4 , a connection plate 108 is fixed on a bottom wall 110 of the carcass 104 and a first part 106A of the conduit 106 extends between the reservoir 102 and the plate 108, in the internal volume V104, while a second part 106B of this conduit extends between the plate and the sprayer 6, outside the internal volume V104.

Le réservoir 102 est alimenté en produit de revêtement pulvérulent par une pompe 112 qui appartient également à l'unité d'alimentation 10 et qui est fixée sur l'extérieur d'une première paroi latérale 114 de la carcasse 104. Un deuxième conduit 116 relie la sortie 112B de la pompe 112 au réservoir 102 et comprend une première partie 116A qui s'étend à l'intérieur du volume interne V104, entre le réservoir 102 et la platine 108, et une deuxième partie 116B qui s'étend entre la platine 108 et la pompe 112, à l'extérieur du volume interne V104.The reservoir 102 is supplied with powder coating product by a pump 112 which also belongs to the supply unit 10 and which is fixed to the outside of a first side wall 114 of the carcass 104. A second conduit 116 connects the outlet 112B of the pump 112 to the reservoir 102 and comprises a first part 116A which extends inside the internal volume V104, between the reservoir 102 and the plate 108, and a second part 116B which extends between the plate 108 and the pump 112, outside the internal volume V104.

Le positionnement de la pompe 112 représenté sur les figures n'est pas limitatif. En variante, la pompe 112 peut être installée sur l'intérieur de la paroi latérale 114, sur le fond 110, notamment du côté de ce fond tourné vers l'extérieur de la carcasse 104, à l'opposé du volume V104, sur le plancher 111, sur le plafond 113 ou sur la deuxième paroi latérale 115 de la carcasse 104.The positioning of the pump 112 shown in the figures is not limiting. Alternatively, the pump 112 can be installed on the inside of the side wall 114, on the bottom 110, in particular on the side of this bottom facing the outside of the carcass 104, opposite the volume V104, on the floor 111, on the ceiling 113 or on the second side wall 115 of the carcass 104.

On définit une direction avant-arrière de l'unité d'alimentation 10 comme une direction parallèle à l'axe Y et orientée dans le même sens que cet axe. Une ouverture O104 d'accès au volume 104 est définie par les bords avant du plancher 111, du plafond 113 et des parois latérales 114 et 115, ces bords avant étant ceux visibles à la figure 1 et sur les inserts B) des figures 2 à 4.A front-rear direction of the power supply unit 10 is defined as a direction parallel to the Y axis and oriented in the same direction as this axis. An opening O104 for access to the volume 104 is defined by the front edges of the floor 111, the ceiling 113 and the side walls 114 and 115, these front edges being those visible at figure 1 and on inserts B) of the figures 2 to 4 .

L'entrée 112A de la pompe 112 est alimentée en produit de revêtement pulvérulent contenu dans un carton 118 disposé sur un support 120.The inlet 112A of the pump 112 is supplied with powdered coating product contained in a carton 118 placed on a support 120.

Dans la configuration de la figure 1, le produit de revêtement pulvérulent peut être acheminé jusqu'au pulvérisateur 6 sous forme fluidisé. Cette position est donc une position de transfert de produit de revêtement, du carton 118 vers le réservoir 102, puis du réservoir 102 vers le pulvérisateur 6. Dans cette position, le support 120 et le carton 118 sont totalement inclus dans le volume interne V104 de la carcasse 104. En d'autres termes, le carton 118 et le support 120 ne font pas saillie hors du volume V104, à travers l'ouverture O104. Le carton 118 et le support 120, qui ne dépassent pas à l'extérieur du volume V104, ne risquent pas de gêner des opérateurs ou des chariots de transport en mouvement au voisinage de la station de poudrage 2.In the configuration of the figure 1 , the powder coating product can be conveyed to the sprayer 6 in fluidized form. This position is therefore a position for transferring the coating product, from the carton 118 to the reservoir 102, then from the reservoir 102 to the sprayer 6. In this position, the support 120 and the carton 118 are completely included in the internal volume V104 of the carcass 104. In other words, the carton 118 and the support 120 do not protrude from the volume V104, through the opening O104. The carton 118 and the support 120, which do not protrude outside the volume V104, do not risk hindering operators or transport trolleys moving in the vicinity of the powder coating station 2.

Avantageusement, le support 120 est équipé d'une table vibrante 121 qui permet de secouer le carton 18 dans la configuration des figures 1 et 2, afin de faciliter le regroupement du produit de revêtement dans son coin inférieur. Une face supérieure de la table vibrante 121 est inclinée et permet de faire reposer le carton 118 avec une configuration inclinée facilitant la concentration du produit de revêtement dans un coin inférieur du carton 118.Advantageously, the support 120 is equipped with a vibrating table 121 which makes it possible to shake the cardboard 18 in the configuration of the figures 1 And 2 , in order to facilitate the grouping of the coating product in its lower corner. An upper face of the vibrating table 121 is inclined and allows the cardboard 118 to rest with an inclined configuration facilitating the concentration of the coating product in a lower corner of the cardboard 118.

Dans la configuration de l'unité d'alimentation 10 représentée aux figures 1 et 2, une canne d'aspiration 122 plonge dans le carton 118 en étant maintenue en place grâce à une équerre 124 fixée sur la deuxième paroi latérale 115 de la carcasse 104.In the configuration of the power supply unit 10 shown in figures 1 And 2 , a suction rod 122 plunges into the cardboard 118 while being held in place by means of a bracket 124 fixed to the second side wall 115 of the carcass 104.

Un troisième conduit 126 relie l'extrémité supérieure de la canne d'aspiration 122 à l'entrée 112A de la pompe 112. Une première partie du conduit 126 s'étend entre la canne d'aspiration 122 et une platine de connexion 128 fixée sur la paroi de fond 110, dans le volume interne V104, alors qu'une deuxième partie de ce conduit s'étend entre la platine 128 et l'entrée 112A de la pompe 112, à l'extérieur du volume interne V104.A third conduit 126 connects the upper end of the suction pipe 122 to the inlet 112A of the pump 112. A first part of the conduit 126 extends between the suction pipe 122 and a connection plate 128 fixed to the bottom wall 110, in the internal volume V104, while a second part of this conduit extends between the plate 128 and the inlet 112A of the pump 112, outside the internal volume V104.

Un fourreau 130 est disposé sur la face interne de la paroi 115 tournée vers le volume V104 et configuré pour recevoir la canne d'aspiration 122 lorsqu'elle n'est pas en place sur l'équerre 124 pour plonger dans le carton 118.A sheath 130 is arranged on the internal face of the wall 115 facing the volume V104 and configured to receive the suction rod 122 when it is not in place on the bracket 124 to plunge into the cardboard 118.

Pour la clarté du dessin, les conduits 106, 116 et 126 sont représentés comme reliant directement entre elles les parties 6, 102, 112 et 122 de la station de poudrage 2 à la figure 1. Les différentes parties de ces conduits sont visibles sur les inserts A) des figures 2 à 4 et ne sont pas représentées sur les inserts B) de ces figures.For clarity of the drawing, the conduits 106, 116 and 126 are shown as directly connecting the parts 6, 102, 112 and 122 of the powdering station 2 to the figure 1 . The different parts of these conduits are visible on the inserts A) of the figures 2 to 4 and are not shown in the inserts B) of these figures.

Le réservoir 102 est équipé de moyens connus en soi permettant de fluidiser le produit de revêtement provenant de la pompe 112, de façon à ce qu'il puisse être acheminé aisément et avec un débit contrôlé au, ou à chacun des, pulvérisateur(s) 6. Pour ce faire, le réservoir 102 peut comprendre une plaque poreuse non représentée au-dessus de laquelle est déversé le produit de revêtement en provenance de la pompe 112 et à travers laquelle s'étend un flux d'air dirigé vers le haut, ce qui a pour effet de mettre en suspension le produit de revêtement dans l'air.The reservoir 102 is equipped with means known per se for fluidizing the coating product coming from the pump 112, so that it can be conveyed easily and with a controlled flow rate to the, or to each, sprayer(s) 6. To do this, the reservoir 102 may comprise a porous plate not shown above into which the coating product is discharged from the pump 112 and through which an upwardly directed air flow extends, which has the effect of suspending the coating product in the air.

Dans la configuration de l'unité d'alimentation 10 représentée aux figures 1 et 2, le carton 118 en place sur le support 120 est disposé sur un côté du volume V104, en étant décalé, parallèlement à l'axe X, par rapport au réservoir 102 et en étant situé en dessous de ce réservoir, le long de l'axe Z. Dans cette configuration, le carton 118 est correctement positionné vis-à-vis de l'équerre 124, en étant situé complètement à l'intérieur du volume V104, pour que la canne d'aspiration 122 puisse plonger dans le volume intérieur de ce carton.In the configuration of the power supply unit 10 shown in Figures 1 and 2 , the cardboard 118 in place on the support 120 is arranged on one side of the volume V104, being offset, parallel to the X axis, relative to the reservoir 102 and being located below this reservoir, along the Z axis. In this configuration, the cardboard 118 is correctly positioned with respect to the bracket 124, being located completely inside the volume V104, so that the suction rod 122 can plunge into the interior volume of this cardboard.

Dans cette configuration, le carton 118 est relativement difficile d'accès. En particulier, si un opérateur devait installer le carton 118 sur le support dans la configuration des figures 1 et 2, il devrait se contorsionner et travailler en partie en porte-à-faux, sauf à pénétrer lui-même dans le volume V104, où il serait gêné par le réservoir 102 et par les équerres 103 et 124 contre lesquelles il pourrait se blesser. En répétant cette opération plusieurs fois par poste de travail, l'opérateur risquerait de se fatiguer prématurément et de souffrir de troubles musculo-squelettiques.In this configuration, the carton 118 is relatively difficult to access. In particular, if an operator were to install the carton 118 on the support in the configuration of the figures 1 And 2 , he would have to contort himself and work partly in a cantilever, unless he himself entered the volume V104, where he would be hindered by the tank 102 and by the brackets 103 and 124 against which he could injure himself. By repeating this operation several times per workstation, the operator would risk tiring prematurely and suffering from musculoskeletal disorders.

Pour pallier cette difficulté, le support 120 est mobile en rotation autour d'un axe Z120, qui est vertical et parallèle à l'axe Z dans l'exemple des figures. Une rotation est un mouvement simple, aisé à mettre en oeuvre avec des moyens connus, tels que des paliers.To overcome this difficulty, the support 120 is movable in rotation around an axis Z120, which is vertical and parallel to the Z axis in the example of the figures. A rotation is a simple movement, easy to implement with known means, such as bearings.

L'axe Z120 traverse le plancher 111, de telle sorte que sa portion située entre le plancher 111 et le plafond 113 est située dans le volume interne V104 de la carcasse 104. Ceci confère une bonne compacité à l'unité d'alimentation 10.The axis Z120 passes through the floor 111, such that its portion located between the floor 111 and the ceiling 113 is located in the internal volume V104 of the carcass 104. This gives good compactness to the power supply unit 10.

Le support 120 peut ainsi passer de la position représentée aux figures 1 et 2 à celle représentée à la figure 3, dans laquelle le support 120 dépasse à l'extérieur du volume V104, à travers l'ouverture O104, de telle sorte qu'un carton 118 est également disposé au moins en partie à l'extérieur du volume V104 en étant facilement accessible pour un opérateur, pour charger un carton sur le support 120 ou décharger un carton du support 120. Cette position est donc une position de chargement/déchargement du support 120 avec des contenants qui, dans ce mode de réalisation, sont des cartons 118.The support 120 can thus move from the position shown to the figures 1 And 2 to that represented in the figure 3 , in which the support 120 protrudes outside the volume V104, through the opening O104, such that a carton 118 is also arranged at least partly outside the volume V104 while being easily accessible for an operator, to load a carton onto the support 120 or unload a carton from the support 120. This position is therefore a position for loading/unloading the support 120 with containers which, in this embodiment, are cartons 118.

Le passage du support 120 de sa position de transfert des figures 1 et 2 à sa position de chargement/déchargement de la figure 3 est réversible. Il peut avoir lieu dans les deux sens.The passage of the support 120 from its transfer position of the figures 1 And 2 to its loading/unloading position of the figure 3 is reversible. It can take place in both directions.

Pour faciliter le travail de l'opérateur et la mise en rotation du support 120 autour de l'axe Z120, le support 120 est équipé de deux poignées 132 et 134 qui s'étendent vers le haut à partir du support, en particulier jusqu'au-dessus d'un carton en place sur le support. Compte tenu de leur géométrie, les poignées sont aisément accessibles, sans nécessité de se courber pour l'opérateur. Elles permettent d'exercer sur le support 120 un couple d'entrainement en rotation de ce support autour de l'axe Z120, sans devoir se pencher de façon importante. Ce couple peut être exercé dans le sens de la flèche R1 à la figure 3, pour passer de la position de chargement/déchargement la position de transfert, ou dans le sens de la flèche R2 à la figure 2, pour passer de la position de transfert à la position de chargement/déchargement.To facilitate the work of the operator and the rotation of the support 120 around the axis Z120, the support 120 is equipped with two handles 132 and 134 which extend upwards from the support, in particular up to above a cardboard in place on the support. Given their geometry, the handles are easily accessible, without the operator having to bend over. They allow a driving torque to be exerted on the support 120 to rotate this support around the axis Z120, without having to bend over significantly. This torque can be exerted in the direction of the arrow R1 at figure 3 , to move from the loading/unloading position to the transfer position, or in the direction of arrow R2 to the figure 2 , to move from the transfer position to the loading/unloading position.

Le support 120 prend donc, en fonction de son orientation autour de l'axe Z120, une première position de chargement/déchargement du carton 118 sur le support 120, qui est représentée à la figure 3, et une deuxième position de transfert du produit de revêtement, qui est représentée aux figures 1 et 2.The support 120 therefore takes, depending on its orientation around the axis Z120, a first position for loading/unloading the cardboard 118 onto the support 120, which is shown in figure 3 , and a second position for transferring the coating product, which is shown in figures 1 And 2 .

Le travail de l'opérateur s'en trouve facilité car l'accès au support 120 pour y déposer le carton 118 contenant le produit de revêtement pulvérulent est facilité dans la position de chargement/déchargement de la figure 3, alors que le carton 118 et le support 120 ne dépassent pas à l'extérieur du volume 104 dans la position de transfert du support 120, ce qui est avantageux en termes de sécurité et en termes de compacité de l'unité d'alimentation 10, donc de la station de poudrage 2.The operator's work is made easier because access to the support 120 to place the cardboard 118 containing the powder coating product there is facilitated in the loading/unloading position of the figure 3 , whereas the cardboard 118 and the support 120 do not protrude outside the volume 104 in the transfer position of the support 120, which is advantageous in terms of safety and in terms of compactness of the supply unit 10, therefore of the powdering station 2.

En pratique l'angle α de rotation du support 120, dans le sens anti-trigonométrique en vue de dessus représentée sur les inserts B) des figures 2 et 3, entre ses première et deuxième positions peut être compris entre 100 et 180°, de préférence entre 120° et 160°, de préférence encore de l'ordre de 135°. En variante, la rotation du support 120 entre ses première et deuxième positions peut être effectuée dans le sens trigonométrique en vue de dessus pour atteindre le même point. Dans ce cas, l'angle de rotation du support a une valeur égale à la différence entre 360° et la valeur de l'angle dans le cas d'une rotation dans le sens anti-trigonométrique.In practice the angle α of rotation of the support 120, in the anti-trigonometric direction in top view shown on the inserts B) of the figures 2 And 3 , between its first and second positions can be between 100 and 180°, preferably between 120° and 160°, more preferably of the order of 135°. Alternatively, the rotation of the support 120 between its first and second positions can be carried out in the trigonometric direction in top view to reach the same point. In this case, the angle of rotation of the support has a value equal to the difference between 360° and the value of the angle in the case of a rotation in the anti-trigonometric direction.

Avantageusement, une troisième position est prévue pour le support 120. Cette troisième position est représentée à la figure 4. Dans cette troisième position, le carton 118 est situé en dessous du réservoir 102, ce qui permet de purger le réservoir en laissant tomber le produit de revêtement pulvérulent qu'il contient par gravité dans le carton 118. Une vanne manchon de purge 105 est prévue en partie basse du réservoir 102 et permet de contrôler la décharge des reliquats de produit de revêtement présents dans le réservoir 102, à travers une ouverture contrôlée par la vanne manchon 105, vers le carton 118 en place sur le support 120 dans sa troisième position.Advantageously, a third position is provided for the support 120. This third position is shown in figure 4 . In this third position, the carton 118 is located below the reservoir 102, which makes it possible to purge the reservoir by letting the powdered coating product it contains fall by gravity into the carton 118. A purge sleeve valve 105 is provided in the lower part of the reservoir 102 and makes it possible to control the discharge of the residues of coating product present in the reservoir 102, through an opening controlled by the sleeve valve 105, towards the carton 118 in place on the support 120 in its third position.

Dans cette troisième position de purge du réservoir 102, le support 120 dépasse à l'extérieur de la carcasse 104, de façon moins marquée que dans la position de chargement/déchargement de la figure 3. Le carton 118 n'est pas réellement accessible mais cela n'est pas important puisque, dans cette configuration, il n'est pas question de charger ou décharger le carton 118 sur le support 120 mais de récupérer le produit de revêtement pulvérulent restant dans le réservoir 102 et s'écoulant à travers l'ouverture contrôlée par la vanne manchon 105.In this third purge position of the tank 102, the support 120 protrudes outside the carcass 104, in a less marked manner than in the loading/unloading position of the figure 3 Box 118 is not really accessible. but this is not important since, in this configuration, it is not a question of loading or unloading the cardboard 118 onto the support 120 but of recovering the powder coating product remaining in the tank 102 and flowing through the opening controlled by the sleeve valve 105.

Cette troisième position rend plus aisée et rapide la purge du réservoir 102 et la récupération du produit de revêtement restant dans ce réservoir, ce qui facilite une opération de changement de produit de revêtement. En effet, le produit de revêtement utilisé précédemment peut être récupéré dans son carton 118 d'origine, ce carton pouvant être stocké jusqu'à une prochaine opération de poudrage au cours de laquelle ce produit sera utilisé. Les changements de produit de revêtement, notamment les changements de couleur, sont donc facilités.This third position makes it easier and faster to drain the reservoir 102 and recover the coating product remaining in this reservoir, which facilitates a coating product change operation. Indeed, the coating product used previously can be recovered in its original carton 118, this carton being able to be stored until a next powder coating operation during which this product will be used. Changes of coating product, in particular color changes, are therefore facilitated.

La troisième position représentée à la figure 4 est une position intermédiaire entre la première position représentée à la figure 3 et la deuxième position représentée aux figures 1 et 2, en ce sens que, en passant de la première position à la deuxième position avec une rotation dans le sens trigonométrique, et vice versa de la deuxième position à la première position avec une rotation dans le sens anti-trigonométrique, le support 120 passe par la troisième position.The third position represented in the figure 4 is an intermediate position between the first position represented in figure 3 and the second position represented in figures 1 And 2 , in the sense that, when passing from the first position to the second position with a rotation in the trigonometric direction, and vice versa from the second position to the first position with a rotation in the anti-trigonometric direction, the support 120 passes through the third position.

Cette troisième position du support 120 peut être atteinte par le support 120, par une rotation dans le sens de la flèche R1 à partir de la première position de chargement/déchargement, d'amplitude moindre que celle correspondant au passage de la première position de chargement/déchargement à la deuxième position de transfert. Une rotation en sens inverse permet de faire passer le support 120 de sa troisième position de purge à sa première position de chargement/déchargement. Cette troisième position du support 120 peut également être atteinte par le support 120, par une rotation dans le sens de la flèche R2 à partir de la deuxième position de transfert, d'amplitude moindre que celle correspondant au passage de la deuxième position de transfert à la première position de chargement/déchargement. Une rotation en sens inverse permet de faire passer le support 120 de sa troisième position de purge à sa deuxième position de transfert.This third position of the support 120 can be reached by the support 120, by a rotation in the direction of the arrow R1 from the first loading/unloading position, of lesser amplitude than that corresponding to the passage from the first loading/unloading position to the second transfer position. A rotation in the opposite direction makes it possible to move the support 120 from its third purge position to its first loading/unloading position. This third position of the support 120 can also be reached by the support 120, by a rotation in the direction of the arrow R2 from the second transfer position, of lesser amplitude than that corresponding to the passage from the second transfer position to the first loading/unloading position. A rotation in the opposite direction makes it possible to move the support 120 from its third purge position to its second transfer position.

En pratique l'angle β de rotation du support 120, dans le sens trigonométrique en vue de dessus représentée sur les inserts B) des figures 2 et 4, entre ses première et troisième positions peut être compris entre 70 et 110°, de préférence entre 80° et 100°, de préférence encore de l'ordre de 90°. En variante, la rotation du support 120 entre ses première et troisième positions peut être effectuée dans le sens anti-trigonométrique en vue de dessus pour atteindre le même point.In practice the angle β of rotation of the support 120, in the trigonometric direction in top view shown on the inserts B) of the figures 2 And 4 , between its first and third positions can be between 70 and 110°, preferably between 80° and 100°, more preferably of the order of 90°. Alternatively, the rotation of the support 120 between its first and third positions can be carried out in the anti-trigonometric direction in top view to reach the same point.

Dans ce qui précède, lorsqu'un angle est défini comme de l'ordre d'une valeur, il est égal à cette valeur à 5° près.In the above, when an angle is defined as of the order of a value, it is equal to that value to within 5°.

Quelle que soit la position du support 120, l'une au moins des poignées 132 et 134 est accessible pour l'opérateur depuis l'extérieur de la carcasse 104, à travers l'ouverture O104, afin d'exercer un couple de rotation autour de l'axe Z120, dans le sens de la flèche R1 ou dans le sens de la flèche R2, selon le mouvement souhaité.Whatever the position of the support 120, at least one of the handles 132 and 134 is accessible to the operator from outside the carcass 104, through the opening O104, in order to exert a rotational torque around the axis Z120, in the direction of the arrow R1 or in the direction of the arrow R2, depending on the desired movement.

Dans le deuxième mode de réalisation représenté aux figures 5 et suivantes, les éléments analogues à ceux du premier mode de réalisation portent les mêmes références et ne sont pas décrits en détail. Dans ce qui suit, si une référence est mentionnée dans la description sans être portée sur une figure ou si elle est portée sur une figure sans être mentionnée dans la description, elle correspond au même élément que celui portant la même référence dans le premier mode de réalisation. Dans ce qui suit, on décrit principalement ce qui distingue le deuxième mode de réalisation du précédent.In the second embodiment shown in figures 5 and following, elements similar to those of the first embodiment bear the same references and are not described in detail. In the following, if a reference is mentioned in the description without being shown in a figure or if it is shown in a figure without being mentioned in the description, it corresponds to the same element as that bearing the same reference in the first embodiment. In the following, we mainly describe what distinguishes the second embodiment from the previous one.

Ce mode de réalisation diffère du précédent en ce qu'un bac rigide 119 est monté sur le support 120 afin de recevoir un sac de produit de revêtement, ce qui correspond à certaines configurations de conditionnement de produit de revêtement parfois dénommées « big bag ». Le bac 119 est, de préférence, réalisé polymère soudé, en acier laqué ou en acier inoxydable poli. Ce bac 119 est fermé par un couvercle 139 équipé d'un tube 141 qui forme une cheminée à travers laquelle une canne d'aspiration 122 plonge dans le bac 119, afin d'y prélever le produit de revêtement pulvérisé aspiré par la pompe 112 à travers le conduit 126, dans la configuration des figures 5 et 6 où le support 120 est dans une position de transfert définie comme dans le premier mode de réalisation.This embodiment differs from the previous one in that a rigid container 119 is mounted on the support 120 in order to receive a bag of coating product, which corresponds to certain coating product packaging configurations sometimes called "big bags". The container 119 is preferably made of welded polymer, lacquered steel or polished stainless steel. This container 119 is closed by a cover 139 equipped with a tube 141 which forms a chimney through which a suction rod 122 plunges into the container 119, in order to take therefrom the sprayed coating product sucked by the pump 112 through the conduit 126, in the configuration of figures 5 And 6 where the support 120 is in a transfer position defined as in the first embodiment.

Les parties 102 à 116 et 121 à 134 de la station de poudrage 2 sont identiques à celles du premier mode de réalisation.Parts 102 to 116 and 121 to 134 of the powdering station 2 are identical to those of the first embodiment.

En particulier, le support 120 est mobile en rotation, dans les deux sens représentés par les flèches R1 et R2 respectivement aux figures 7 et 6, entre une première position de chargement/déchargement d'un sac de produit de revêtement dans le bac 119 et une position de transfert de produit de revêtement du volume interne du bac 119 vers le pulvérisateur 6, en passant par le réservoir 102 de produit de revêtement fluidisé.In particular, the support 120 is movable in rotation, in the two directions represented by the arrows R1 and R2 respectively at figures 7 And 6 , between a first position for loading/unloading a bag of coating product into the tank 119 and a position for transferring coating product from the internal volume of the tank 119 to the sprayer 6, passing through the reservoir 102 of fluidized coating product.

Dans la première position de chargement/déchargement du support 120 représentée à la figure 7 et selon un aspect qui n'est pas représenté, le couvercle 139 est retiré avant évacuation d'un sac de produit de revêtement partiellement ou totalement consommé et avant mise en place d'un nouveau sac de produit de revêtement dans le bac 119. Après cette opération, le couvercle 139 est remis en place sur le bac 119, toujours dans cette position.In the first loading/unloading position of the support 120 shown in the figure 7 and according to an aspect which is not shown, the cover 139 is removed before evacuating a bag of partially or totally consumed coating product and before placing a new bag of coating product in the tank 119. After this operation, the cover 139 is replaced on the tank 119, still in this position.

Le couvercle 139 et le tube 141 permettent de confiner le volume intérieur du bac 119. Ceci évite que du produit de revêtement pulvérulent se dépose sur les parties internes de l'unité d'alimentation 10. Ceci limite les risques de pollution de ce produit de revêtement pulvérulent par des particules externes.The cover 139 and the tube 141 make it possible to confine the internal volume of the container 119. This prevents powdered coating product from being deposited on the internal parts. of the supply unit 10. This limits the risks of pollution of this powder coating product by external particles.

Le tube 141 est positionné sur le couvercle 139 de telle sorte qu'il est aligné avec la canne d'aspiration 122 dans la deuxième position de transfert représentée aux figures 5 et 6, ainsi qu'avec l'ouverture de sortie du réservoir 102 contrôlée par la vanne manchon 105, dans la troisième configuration représentée à la figure 8, qui est optionnelle comme dans le premier mode de réalisation.The tube 141 is positioned on the cover 139 such that it is aligned with the suction rod 122 in the second transfer position shown in figures 5 And 6 , as well as with the outlet opening of the tank 102 controlled by the sleeve valve 105, in the third configuration shown in figure 8 , which is optional as in the first embodiment.

Dans cette troisième position, le tube 141 assure le guidage du produit de revêtement vers le volume intérieur du bac 119 et limite les risques de pollution du volume V104.In this third position, the tube 141 ensures the guidance of the coating product towards the interior volume of the tank 119 and limits the risks of pollution of the volume V104.

Quel que soit le mode de réalisation, le nombre de poignées 132, 134 ou équivalentes équipant le support 120 pour y appliquer un couple de rotation entre ses positions mentionnées ci-dessus, peut être différent de deux, en particulier égal à un ou supérieur ou égal à trois. En outre, ces poignées peuvent avoir une géométrie différente de celle représentée sur les figures.Whatever the embodiment, the number of handles 132, 134 or equivalent equipping the support 120 to apply a rotational torque between its positions mentioned above, may be other than two, in particular equal to one or greater than or equal to three. In addition, these handles may have a geometry different from that shown in the figures.

En variante, la carcasse 104 peut avoir une géométrie différente de celle représentée sur les figures et son ouverture peut être orientée différemment.Alternatively, the carcass 104 may have a geometry different from that shown in the figures and its opening may be oriented differently.

En variante, le mouvement du support entre ses première et deuxième positions et, éventuellement entre ces positions et la troisième position, est un mouvement de translation circulaire, autour de deux axes de rotation. Dans ce cas, l'angle de rotation entre les différentes positions est limité à 180°.Alternatively, the movement of the support between its first and second positions and, possibly between these positions and the third position, is a circular translational movement, around two axes of rotation. In this case, the angle of rotation between the different positions is limited to 180°.

Que ce soit avec un mouvement de rotation ou de translation circulaire, le déplacement du support entre ses positions est bien maîtrisé et n'induit pas d'encombrement de l'espace à l'extérieur de la carcasse 104, ce qui serait le cas avec un mouvement de translation.Whether with a rotational or circular translational movement, the movement of the support between its positions is well controlled and does not cause any obstruction of the space outside the carcass 104, which would be the case with a translational movement.

Selon une autre variante non représentée, applicable un mouvement de rotation ou de translation circulaire, il est prévu des moyens d'indexation, c'est-à-dire d'arrêt, du support dans chacune de ses première et deuxième positions, et éventuellement dans sa troisième positon.According to another variant not shown, applicable to a rotational or circular translational movement, means are provided for indexing, that is to say stopping, the support in each of its first and second positions, and possibly in its third position.

Selon encore une autre variante non représentée, le support 120 est entrainé électriquement, par un moteur, ou pneumatiquement, par un vérin rotatif, entre ses positions. Dans ce cas, les poignées 132 et 134 peuvent être omises.According to yet another variant not shown, the support 120 is driven electrically, by a motor, or pneumatically, by a rotary cylinder, between its positions. In this case, the handles 132 and 134 can be omitted.

L'invention n'est pas limitée aux modes de réalisation décrit. En particulier, les modes de réalisation et variantes envisagées ci-dessus peuvent être combinés entre eux.The invention is not limited to the embodiments described. In particular, the embodiments and variants envisaged above can be combined with each other.
