Abstract

Part (36) of the curved rear cabin wall (16), actuator-operated (43), swings aside on pivoted (38) support arms (40). One arm (60) of the carrousel (12), carrying the next workpiece on a turntable (62), enters the cabin as the hub (58) rotates on a vertical axis, just outside. Reclosing the rear, the operator sprays glazing enamel through a front opening (48), using a piston applicator and rotating the workpiece by engaging a belt drive within the arm (60). Further workpieces are meantime mounted on following turntables. Inclined air-curtains (50, 52) protect the operator. Air circulation (56) facilitates the deposition of excess fluid, which runs down the walls into a basin for re-use. Corner fitments (46) contain extraction vents and lighting.

Description

La présente invention a pour objet une cabine de traitement de pièces par pulvérisation, notamment d'émaillage de pièces céramiques.The present invention relates to a spraying parts treatment booth, in particular for glazing ceramic parts.

Dans l'industrie du sanitaire notamment, les pièces en céramique sont moulées puis elles sont recouvertes par pulvérisation d'une couche d'émail avant de subir une cuisson qui assure la transformation de la céramique en lui conférant des propriétés de résistance mécanique suffisantes pour leurs fonctions. De plus, cette cuisson provoque une fusion de l'émail avec un autolissage ainsi que l'apparition des couleurs générées par les pigments contenus dans ladite couche d'émail.In the sanitary industry in particular, the ceramic parts are molded and then they are covered by spraying with a layer of enamel before undergoing a firing which ensures the transformation of the ceramic by giving it properties of mechanical resistance sufficient for their functions. In addition, this firing causes a melting of the enamel with self-leveling as well as the appearance of the colors generated by the pigments contained in said layer of enamel.

Actuellement, la pièce est disposée dans une cabine de pulvérisation équipée en son centre d'une tournette, c'est-à-dire une platine montée à rotation autour de son axe vertical central, prévue pour recevoir la pièce. La cabine de pulvérisation comprend une ouverture frontale permettant le transfert avant/arrière des pièces. Un opérateur, extérieur à la cabine, manoeuvre un pistolet alimenté en émail sous forme de barbotine épaisse et projette cet émail en direction de la pièce qui est mise en rotation manuellement pour permettre l'accès à toutes les faces, ceci grâce à la tournette.Currently, the part is arranged in a spray booth equipped in its center with a spinner, that is to say a plate rotatably mounted about its central vertical axis, designed to receive the part. The spray booth includes a front opening for forward / backward transfer of parts. An operator, outside the cabin, maneuvers a gun supplied with enamel in the form of thick slip and projects this enamel towards the workpiece which is rotated manually to allow access to all sides, this thanks to the spinner.

L'émail est déposé en une couche aussi régulière que possible par l'opérateur en évitant surtout la présence de manques.The enamel is deposited in as even a layer as possible by the operator, above all avoiding the presence of gaps.

L'émail est dilué à l'eau si bien que celle-ci est absorbée par la céramique, quasi-instantanément, figeant alors la couche d'émail.The enamel is diluted with water so that it is absorbed by the ceramic, almost instantly, freezing the layer of enamel.

L'opérateur retire la pièce ainsi préparée de la tournette après l'avoir translatée vers lui et dispose cette pièce émaillée sur un chariot de transfert.The operator removes the part thus prepared from the spinner after having translated it towards him and places this enameled part on a transfer carriage.

Cette opération d'émaillage par pulvérisation qui apparaît comme simple, engendre en réalité de nombreux problèmes.This spray enameling operation, which appears to be simple, in reality causes many problems.

Une première difficulté réside dans le chargement-déchargement des pièces qui nécessite un déport de l'opérateur pour accéder à la tournette, même si un montage sur glissières permet d'améliorer ces chargements-déchargements, car les pièces sont lourdes pour la plupart.A first difficulty lies in the loading-unloading of the parts which requires an offset from the operator to access the spinner, even if mounting on runners makes it possible to improve these loading-unloading, since the parts are heavy for the most part.

De même, la rotation manuelle de la tournette, en plus des mouvements de l'opérateur pour accéder à toutes les surfaces à émailler, conduit à des problèmes physiques non négligeables.Similarly, manual rotation of the spinner, in addition to the operator's movements to access all the surfaces to be glazed, leads to significant physical problems.

Il faut savoir également que l'émail sous forme pulvérisée est nocif pour les opérateurs et qu'il est nécessaire de respecter des règlementations très strictes en la matière qui définissent des nombres de particules/unité de volume d'air.You should also know that enamel in spray form is harmful to operators and that it is necessary to comply with very strict regulations in this area which define the number of particles / unit of air volume.

Aussi les opérateurs sont, la plupart du temps, réduits au port d'un masque antipoussière, ce qui est toujours une contrainte fortement préjudiciable au confort.Also operators are, most of the time, reduced to wearing a dust mask, which is always a constraint strongly detrimental to comfort.

On comprend également que l'émail projeté et non déposé sur la pièce s'accumule sur la paroi interne de la cabine pour une grande part et que cet émail est récupéré par gravité, en vue de son recyclage, dans un bac amovible disposé dans le fond de la cabine.It is also understood that the enamel projected and not deposited on the part accumulates on the internal wall of the cabin for a large part and that this enamel is recovered by gravity, with a view to its recycling, in a removable tray placed in the bottom of the cabin.

La partie projetée comprenant les particules légères est aspirée par des groupes de forte puissance équipés de filtres. On constate que les volumes aspirés sont très importants et que la masse d'émail récupérée est non moins importante. Contrairement au bac, qui est un moyen simple et aisé de collecte, le nettoyage des filtres des groupes d'aspiration est plus long et plus complexe. L'investissement pour le traitement de l'environnement est très lourd et la maintenance des moyens reste importante.The projected part comprising the light particles is sucked up by high power groups equipped with filters. It can be seen that the volumes sucked in are very large and that the mass of enamel recovered is no less significant. Unlike the bin, which is a simple and easy means of collection, cleaning the filters of the suction groups is longer and more complex. The investment for the treatment of the environment is very heavy and the maintenance of the means remains important.

La présente invention a pour objet une cabine de traitement de pièces par pulvérisation qui évite toute sortie de particules du produit pulvérisé par l'ouverture frontale, au-delà des normes en vigueur, qui permet un chargement-déchargement plus aisé, qui laisse un temps de repos à la pièce qui vient d'être traitée, qui assure une mise en rotation commandée de la pièce, qui reste simple avec une maintenance réduite, qui favorise la récupération par gravité de l'émail et réduit d'autant la quantité de produit filtrée, et qui conserve la possibilité pour l'opérateur de mettre en oeuvre son savoir-faire dans des conditions d'ergonomie améliorées.The subject of the present invention is a spraying parts treatment booth which prevents any exit of particles of the sprayed product by the front opening, beyond the standards in force, which allows easier loading-unloading, which leaves the part that has just been treated to rest, which ensures controlled rotation of the part, which remains simple with maintenance reduced, which promotes gravity recovery of the enamel and therefore reduces the amount of product filtered, and which retains the possibility for the operator to use his know-how under improved ergonomic conditions.

A cet effet, la cabine de pulvérisation selon l'invention, d'un produit sur une pièce notamment d'une barbotine d'émail sur une pièce en céramique verte, comprenant une paroi frontale munie d'une ouverture prévue pour permettre l'accès à la pièce à l'aide d'un pistolet de pulvérisation tenu par un opérateur, une paroi arrière, deux parois latérales droite et gauche, une tournette supportant la pièce se caractérise en ce qu'elle comprend une paroi arrière courbe, des moyens d'émission d'un rideau d'air au droit de l'ouverture et des moyens d'aspiration latéraux disposés sensiblement à l'angle des parois latérales et de la paroi frontale.To this end, the spray booth according to the invention, of a product on a part in particular of an enamel slip on a green ceramic part, comprising a front wall provided with an opening provided to allow access to the workpiece using a spray gun held by an operator, a rear wall, two right and left side walls, a spinner supporting the workpiece is characterized in that it comprises a curved rear wall, means for 'emission of an air curtain to the right of the opening and lateral suction means arranged substantially at the angle of the side walls and the front wall.

Selon un mode de réalisation préférentiel, les moyens d'émission d'un rideau d'air sont disposés en partie haute et basse de l'ouverture.According to a preferred embodiment, the emission means of an air curtain are arranged in the upper and lower part of the opening.

Selon une autre caractéristique de l'invention, la cabine comprend une embase centrale avec une motorisation pour l'entraînement en rotation, comportant au moins deux bras dont les extrémités supportent chacune une tournette, l'embase centrale étant disposée à proximité immédiate de ladite cabine et la longueur des bras étant telle que la tournette passe sensiblement par le centre de la cabine, ainsi qu'une porte de passage des bras et des tournettes.According to another characteristic of the invention, the cabin comprises a central base with a motorization for the rotary drive, comprising at least two arms, the ends of which each support a spinner, the central base being arranged in the immediate vicinity of said cabin and the length of the arms being such that the spinner passes substantially through the center of the cabin, as well as a door for the passage of the arms and spinner.

Plus particulièrement, les moyens d'entraînement en rotation de la seule tournette en place dans la cabine sont intégrés à l'embase centrale.More particularly, the means for rotating the single spinner in place in the cabin are integrated into the central base.

Ces moyens d'entraînement en rotation comprennent un bras d'entraînement mobile en rotation par rapport à l'une de ses extrémités autour d'un axe, un moteur et un premier ensemble de poulies et d'une courroie, l'une des poulies étant entraînée en rotation par l'arbre du moteur, un galet cranté solidaire de la poulie et un second ensemble de poulies, l'une étant solidaire de l'arbre de la tournette et d'une courroie crantée sur l'extérieur et prévue pour coopérer avec le galet cranté dans une première position du bras d'entraînement et prévue pour laisser passer le bras dans une seconde position pendant les mouvements de rotation de l'embase centrale.These rotary drive means comprise a drive arm movable in rotation relative to one of its ends about an axis, a motor and a first set of pulleys and a belt, one of the pulleys being driven in rotation by the motor shaft, a roller notched integral with the pulley and a second set of pulleys, one being integral with the spindle shaft and a notched belt on the outside and designed to cooperate with the notched roller in a first position of the drive and provided to allow the arm to pass into a second position during the rotational movements of the central base.

Le bras d'entraînement comprend un vérin de manoeuvre.The drive arm includes an actuator.

Selon un perfectionnement destiné à améliorer l'ergonomie, il est prévu des moyens de réglage en translation de la position de l'embase centrale par rapport à l'opérateur.According to an improvement intended to improve ergonomics, means are provided for translational adjustment of the position of the central base relative to the operator.

Selon un perfectionnement de l'invention, un tablier escamotable sur la face frontale est prévu pour diminuer les dimensions de l'ouverture en position de travail et pour laisser passer le bras et la tournette lors des mouvements de l'embase centrale.According to an improvement of the invention, a retractable apron on the front face is provided to reduce the dimensions of the opening in the working position and to allow the arm and the spinner to pass during the movements of the central base.

Afin d'améliorer l'ergonomie, la hauteur de l'arbre d'entraînement de chaque tournette est adaptée en fonction de la taille de l'utilisateur.In order to improve ergonomics, the height of the drive shaft of each spinner is adapted according to the size of the user.

En partie inférieure, les parois frontale, latérales et arrière se conjuguent pour former une trémie 26 dont l'ouverture débouche dans un bac de récupération 28, amovible.In the lower part, the front, side and rear walls combine to form a hopper 26, the opening of which opens into a removable collecting tank 28.

L'ensemble de la cabine repose sur des pieds 30 formant châssis.The entire cabin rests on feet 30 forming a chassis.

La paroi latérale droite 18 comprend une armoire de commande 32.The right side wall 18 includes a control cabinet 32.

La paroi latérale gauche 20 comprend des moyens de réglage 34 en translation des moyens de transfert 12 des pièces, avec un volant de réglage 35 qui permet d'éloigner ou de rapprocher de l'opérateur ces moyens de transfert et notamment la pièce qu'ils portent. Sur la figure 1, la double flèche indique la direction de ce mouvement de translation avant/arrière par rapport à l'opérateur.The left side wall 20 comprises adjustment means 34 in translation of the transfer means 12 for the parts, with an adjustment wheel 35 which makes it possible to move these transfer means, and in particular the part they carry. In FIG. 1, the double arrow indicates the direction of this forward / backward translational movement relative to the operator.

La paroi arrière 16 est équipée d'une porte 36, montée pivotante autour d'un axe 38, vertical, passant par le centre de courbure de la paroi arrière.The rear wall 16 is equipped with a door 36, pivotally mounted about a vertical axis 38, passing through the center of curvature of the rear wall.

La porte est supportée par des bras rayonnants 40. Ces bras rayonnants sont disposés en parties haute et basse de la cabine.The door is supported by radiating arms 40. These radiating arms are arranged in the upper and lower parts of the cabin.

La porte pivote à l'intérieur de la paroi arrière courbe avec les jeux nécessaires, parallèlement à celle-ci.The door pivots inside the curved rear wall with the necessary clearances, parallel to it.

Deux poutres transversales haute 42 et basse 44 assurent la rigidité mécanique du montage, tandis qu'un vérin pneumatique 43 permet la manoeuvre de ladite porte.Two high 42 and low 44 transverse beams ensure the mechanical rigidity of the assembly, while a pneumatic cylinder 43 allows the operation of said door.

La paroi frontale 14 comprend latéralement des moyens d'éclairage 46.The front wall 14 laterally comprises lighting means 46.

Une ouverture 48 est ménagée sur cette paroi frontale et en parties haute et basse, cette ouverture est équipée de rampes 50 de soufflage d'air comprimé formant un rideau d'air avec une orientation vers l'intérieur de la cabine suivant un angle symbolisé par les flèches 52.An opening 48 is formed on this front wall and in the upper and lower parts, this opening is fitted with ramps 50 for blowing compressed air forming an air curtain with an orientation towards the interior of the cabin at an angle symbolized by the arrows 52.

De telles rampes sont vendues par exemple dans le commerce sous la dénomination "Transvector".Such ramps are sold, for example, commercially under the name "Transvector".

Latéralement, il est prévu des aspirations 54 reliées au piquage 24 des moyens de ventilation. Ces aspirations 54 sont disposées à proximité immédiate de la paroi frontale, juxtaposées aux moyens d'éclairages 46 disposés dans les angles.Laterally, there are provided aspirations 54 connected to the tap 24 of the ventilation means. These aspirations 54 are arranged in the immediate vicinity of the front wall, juxtaposed with the lighting means 46 arranged in the corners.

La circulation des flux d'air dans la cabine est symbolisée par la flèche 56, et l'intérêt de cette circulation apparaîtra plus spécifiquement au cours de la description du fonctionnement ci-après.The circulation of the air flows in the cabin is symbolized by the arrow 56, and the advantage of this circulation will appear more specifically during the description of the operation below.

Les moyens de transfert 12 des pièces sont représentés en détail sur les figures 4 et 5 et schématiquement sur la figure 1 notamment.The means 12 for transferring the parts are shown in detail in Figures 4 and 5 and schematically in Figure 1 in particular.

Ces moyens de transfert 12 comprennent une embase centrale 58 avec une motorisation intégrée, montée à rotation, supportant dans l'exemple représenté trois bras 60 disposés à 120°, de façon rayonnante.These transfer means 12 comprise a central base 58 with an integrated motorization, mounted for rotation, supporting in the example shown three arms 60 arranged at 120 °, radiantly.

L'embase centrale est disposée à proximité immédiate de la paroi latérale gauche et la longueur des bras est telle que leurs extrémités passent sensiblement au centre de la cabine. L'embase centrale 58 est reliée, ainsi qu'indiqué précédemment, aux moyens de réglage en translation 34.The central base is arranged in the immediate vicinity of the left side wall and the length of the arms is such that their ends pass substantially through the center of the cabin. The central base 58 is connected, as indicated above, to the translation adjustment means 34.

Chaque bras est équipé, à son extrémité, d'une tournette 62, c'est-à-dire d'une platine montée à rotation.Each arm is equipped, at its end, with a turner 62, that is to say a plate mounted for rotation.

Il est également prévu, en plus de la motorisation de l'embase centrale, des moyens d'entraînement en rotation 64 de la tournette sur elle-même.It is also provided, in addition to the motorization of the central base, means for driving in rotation 64 the spinner on itself.

Ces moyens d'entraînement en rotation 64 de la tournette comprennent un bâti fixe 66 par rapport à l'embase centrale et disposé à l'intérieur de cette embase, supportant un bras d'entraînement 68 mobile en rotation autour d'un axe 70, mouvement symbolisé par la double flèche 72.These rotational drive means 64 for the spinner include a fixed frame 66 relative to the central base and disposed inside this base, supporting a drive arm 68 movable in rotation about an axis 70, movement symbolized by the double arrow 72.

Une poulie crantée 74 est montée sur le bâti fixe 66.A toothed pulley 74 is mounted on the fixed frame 66.

Le bras d'entraînement 68 comprend une poulie crantée 76. Une courroie 78 est tendue entre les poulies crantées 74 et 76. La poulie 74 est solidaire de l'arbre d'entraînement 80 d'un moteur 82.The drive arm 68 comprises a toothed pulley 76. A belt 78 is stretched between the toothed pulleys 74 and 76. The pulley 74 is integral with the drive shaft 80 of a motor 82.

Un galet cranté 84 est monté solidaire et coaxial sur la poulie 76 par une vis de liaison 86.A notched roller 84 is mounted integral and coaxial with the pulley 76 by a connecting screw 86.

La manoeuvre du bras 68 est obtenue par un vérin 88 dont le piston 90 se déplace en translation dans un sens et dans l'autre suivant la flèche 92.The operation of the arm 68 is obtained by a jack 88 whose piston 90 moves in translation in one direction and in the other according to arrow 92.

Chaque bras comprend deux poulies 94, 96 dont une 94 est située à proximité immédiate du galet cranté 84, et l'autre 96 est solidaire de l'arbre d'entraînement 98 de la tournette portée par le bras. On notera que cet arbre d'entraînement 98 dispose d'un berceau adapté à la pièce et sa hauteur sera fonction de la taille de l'opérateur afin de proposer une bonne ergonomie.Each arm comprises two pulleys 94, 96, one of which 94 is located in the immediate vicinity of the notched roller 84, and the other 96 is integral with the drive shaft 98 of the spinner carried by the arm. Note that this drive shaft 98 has a cradle adapted to the room and its height will depend on the size of the operator in order to provide good ergonomics.

Une courroie crantée à l'extérieur 100 assure la liaison entre les deux poulies 94 et 96. La denture est prévue pour coopérer avec la denture du galet cranté 84.An external toothed belt 100 provides the connection between the two pulleys 94 and 96. The teeth are provided to cooperate with the teeth of the toothed roller 84.

L'ensemble des moyens d'entraînement 64 est positionné en sorte d'entraîner la tournette lorsque le bras est situé dans la cabine, en position de travail, chargée d'une pièce représentée en trait mixte sur la seule figure 2, afin de ne pas nuire à la clarté des autres figures, et référencée à des fins de repérage 102.All of the drive means 64 are positioned so as to drive the spinner when the arm is located in the cabin, in the working position, loaded with a part shown in phantom in FIG. 2 alone, so as not to not detract from the clarity of the other figures, and referenced for locating purposes 102.

Le fonctionnement d'une telle cabine est maintenant décrit. L'opérateur charge une pièce 102 en céramique, dite verte car elle n'a subi aucune cuisson, sur la tournette 62 en position A sur la figure 1.The operation of such a cabin is now described. The operator loads a ceramic piece 102, known as green because it has not undergone any firing, on the spinner 62 in position A in FIG. 1.

L'opérateur se déplace et actionne sur l'armoire de commande l'interrupteur de mise en rotation de l'embase centrale 58, ce qui fait passer la pièce de la position A à la position B, sans risque pour l'opérateur qui est en dehors du champ de rotation des bras 60. Parallèlement, le vérin 43 a ouvert la porte 36 pour laisser passer le bras 60 et la tournette 62, qui en est solidaire, l'ensemble se déplace de la position B à la position C.The operator moves and actuates on the control cabinet the rotation switch of the central base 58, which moves the part from position A to position B, without risk for the operator who is outside the field of rotation of the arms 60. At the same time, the jack 43 has opened the door 36 to let the arm 60 pass and the spinner 62, which is integral therewith, the assembly moves from position B to position C.

L'interrupteur général de l'installation assure, lors de la mise en service de la cabine, l'éclairage 46, la mise en route du groupe d'aspiration, et l'alimentation des rampes 50 de soufflage en air comprimé.The general switch of the installation ensures, when the cabin is put into service, the lighting 46, the start-up of the suction group, and the supply of the supply air ramps 50 with compressed air.

L'opérateur peut alors se placer devant la paroi frontale et, à l'aide d'un pistolet de pulvérisation de type connu, il dépose une couche de barbotine épaisse d'émail. Au fur et à mesure, il actionne, par exemple à l'aide d'un contacteur au pied, les moyens d'entraînement de la tournette. En effet, lorsque le bras est en place dans la cabine, le galet cranté 84 est amené au contact de la courroie 100 crantée à l'extérieur par la manoeuvre du vérin 88 dont le piston est mis en saillie. Le moteur 82 est mis en marche par ledit contacteur au pied, ce qui fait tourner la poulie 74 qui entraîne la courroie 78, met en rotation la poulie 76 et donc le galet cranté 84 qui en est solidaire.The operator can then stand in front of the front wall and, using a known type of spray gun, deposits a thick layer of enamel slip. At gradually, it actuates, for example using a foot switch, the drive means of the spinner. In fact, when the arm is in place in the cabin, the notched roller 84 is brought into contact with the belt 100 notched outside by the operation of the jack 88, the piston of which projects. The motor 82 is started by said foot switch, which rotates the pulley 74 which drives the belt 78, rotates the pulley 76 and therefore the notched roller 84 which is integral therewith.

La courroie 100 est à son tour mise en rotation, ce qui fait tourner la pièce supportée par la tournette.The belt 100 is in turn rotated, which rotates the part supported by the spinner.

L'opérateur agissant sur le volant de réglage 35 approche ou éloigne la pièce pour travailler avec une bonne position ergonomique. Ce réglage est généralement effectué une seule fois au début de la série de pièces identiques à traiter, en fonction des dimensions.The operator acting on the adjustment wheel 35 approaches or moves the workpiece away to work with a good ergonomic position. This adjustment is generally made only once at the start of the series of identical parts to be treated, depending on the dimensions.

On constate, durant toute la phase de pulvérisation, que les particules qui ne sont pas déposées sur la pièce, sont projetées vers le fond de la cabine et se déposent sur la paroi du fond pour les plus grosses.It is noted, throughout the spraying phase, that the particles which are not deposited on the part, are projected towards the bottom of the cabin and are deposited on the bottom wall for the larger ones.

Les particules plus fines se déposent aussi car le flux d'air généré par les rampes se trouve avoir une vitesse nulle le long de la paroi courbe, ce qui facilite le dépôt par gravité.The finer particles are also deposited because the air flow generated by the ramps is found to have a zero speed along the curved wall, which facilitates the deposition by gravity.

Le flux d'air reprend ensuite un peu de vitesse le long des parois latérales jusqu'aux aspirations 54, sous l'effet de la dépression.The air flow then picks up a little speed along the side walls until the aspirations 54, under the effect of the depression.

On peut remarquer que l'opérateur devant l'ouverture 48 est hors de la circulation des particules, si bien que la densité à laquelle il est soumis reste inférieure à celle de la norme fixant à 1 ppm le niveau maximal.It can be noted that the operator in front of the opening 48 is out of the circulation of the particles, so that the density to which it is subjected remains lower than that of the standard fixing at 1 ppm the maximum level.

Une fois la pièce terminée, l'opérateur charge un nouveau produit vert sur la tournette de la position A puis se présente devant le panneau de commande pour mettre en rotation l'embase centrale 58 de façon que la pièce finie passe de B à C et la nouvelle pièce à traiter de A à B.Once the part is finished, the operator loads a new green product onto the spinner in position A, then comes to the control panel to rotate the central base 58 so that the finished part goes from B to C and the new part to be treated from A to B.

En C, la pièce émaillée "sèche" dans le sens où la céramique poreuse absorbe l'eau de la barbotine de l'émail de la couche déposée.In C, the enamel piece "dries" in the sense that the porous ceramic absorbs the water from the slip of the enamel of the deposited layer.

L'opérateur traite alors la deuxième pièce de la même façon que précédemment. Une fois finie, l'opérateur fait à nouveau tourner l'embase centrale, après avoir chargé la tournette en A.The operator then treats the second part in the same way as before. Once finished, the operator turns the central base again, after having loaded the spinner at A.

Le cycle s'achève par le traitement de la troisième pièce.The cycle ends with the processing of the third part.

Lors des cycles suivants, il faudra que l'opérateur retire la pièce "séchée" avant de charger un produit vert. Le fonctionnement semi-continu est amorcé.During subsequent cycles, the operator will have to remove the "dried" part before loading a green product. Semi-continuous operation is initiated.

Afin de diminuer les dimensions de l'ouverture 48 et d'éviter tout retour de particules, il est possible, selon un perfectionnement de l'invention, de disposer un tablier escamotable en partie inférieure, qui est déplacé lors de chaque mouvement en rotation de l'embase centrale afin de laisser passer bras et tournette.In order to reduce the dimensions of the opening 48 and to avoid any return of particles, it is possible, according to an improvement of the invention, to have a retractable apron in the lower part, which is moved during each rotation movement of the central base in order to let the arm and spinner pass.

De plus, on constate que la majeure partie de l'émail est récupérée par le bac 28 en partie inférieure, grâce à la trémie 26.In addition, it can be seen that most of the enamel is recovered by the tray 28 in the lower part, thanks to the hopper 26.

L'agencement et la forme courbe de la paroi arrière y sont pour beaucoup. En effet, les grosses particules s'accumulent sur la paroi en une couche suffisamment épaisse pour qu'elle ne sèche pas et que l'adhérence soit minimale sur la paroi. Dans ce but, la porte devra coulisser devant la paroi arrière avec un jeu suffisant pour laisser subsister l'épaisseur d'émail nécessaire.The arrangement and the curved shape of the rear wall have a lot to do with it. Indeed, large particles accumulate on the wall in a sufficiently thick layer so that it does not dry and that the adhesion is minimal on the wall. For this purpose, the door must slide in front of the rear wall with sufficient play to allow the necessary thickness of enamel to remain.

Selon un autre perfectionnement de l'invention, les tournettes sont équipées de tout moyen adapté pour assurer un blocage en rotation de l'arbre 98, de l'une ou de l'autre des poulies 94 ou 96, ou encore de la courroie 100. Il convient en effet d'immobiliser la pièce pendant que l'embase centrale est en mouvement.According to another improvement of the invention, the spindles are equipped with any means suitable for ensuring a rotation blocking of the shaft 98, of one or the other of the pulleys 94 or 96, or also of the belt 100 It is indeed necessary to immobilize the part while the central base is in motion.

Selon un perfectionnement complémentaire, l'accélération et la décélération de la rotation de l'embase centrale seront rendues progressives par un pilotage adapté de la motorisation des moyens de transfert.According to a further improvement, the acceleration and deceleration of the rotation of the central base will be made progressive by a suitable control of the motorization of the transfer means.
