Description

BOL DE PULVERISATION, DISPOSITIF DE PROJECTION SPRAY BOWL, PROJECTION DEVICE

INCORPORANT UN TEL BOL ET INSTALLATION DEINCORPORATING SUCH A BOWL AND INSTALLATION OF

PROJECTION INCORPORANT UN TEL DISPOSITIFPROJECTION INCORPORATING SUCH A DEVICE

L'invention a trait à un bol de pulvérisation pour un projecteur rotatif de produit de revêtement. L'invention a également trait à un dispositif de projection de produit de revêtement comprenant un tel bol, ainsi qu'à une installation de projection de produit de revêtement incorporant un tel dispositif.The invention relates to a spray bowl for a rotary coating product sprayer. The invention also relates to a coating product projection device comprising such a bowl, as well as to a coating product projection installation incorporating such a device.

Dans une installation de projection de produit de revêtement, il est connu de pulvériser le produit au moyen d'un élément rotatif dénommé bol ou coupelle, alimenté en produit et tournant à une vitesse comprise entre 2 000 et 100 000 tours/minute . Aux vitesses considérées, le bol doit être le plus léger possible et équilibré afin d'éviter, autant que faire se peut, les balourds, notamment si ses moyens d'entraînement comprennent une turbine à palier à air et/ou magnétique. II est connu, par exemple de WO-A-94/12 286, de relier un bol à un rotor au moyen d'une couronne d'emboîtement susceptible d'expansion radiale. Il est également connu, par exemple de WO-A-01/66 396 ou de US-A-4,473 , 188, d'utiliser des moyens de couplage magnétique entre un bol et le rotor d'une turbine. Dans ces dispositifs, l'effort à exercer pour désaccoupler le bol du rotor doit être intense. Dès que ces éléments sont séparés, l'effort de couplage magnétique décroît très fortement, de sorte que rien ne s'oppose au mouvement d'arrachement du bol. Il en résulte un risque pour un opérateur d'échapper un bol lors de son démontage, car l'effort résistant du couplage magnétique chute très rapidement dès que le bol est séparé du rotor. Or, la chute d'un tel bol conduit généralement à l' endommagement de son arête de pulvérisation, ce qui dégrade la qualité de la pulvérisation obtenue. En d'autres termes, lorsqu'un bol chute sur le sol, il n'est pas rare de devoir le remplacer, alors qu'un tel matériel est, de part le soin apporté à sa réalisation, coûteux. Les dispositifs connus comprennent un ou plusieurs aimants constituant ensemble un dispositif d'aimantation annulaire. Ceci impose à ce ou ces aimants d'être suffisamment volumineux pour générer un champ magnétique intense, ce qui nuit à la compacité du projecteur. En outre, le poids et l'inertie du bol sont relativement importants, tout particulièrement dans le cas où le bol porte le ou les aimants permanents. Enfin, les aimants doivent faire l'objet d'un montage mécanique particulier afin qu'ils ne risquent pas d'éclater sous l'effet des efforts centrifuges .In a coating product spraying installation, it is known to spray the product by means of a rotary element called a bowl or cup, supplied with product and rotating at a speed of between 2,000 and 100,000 revolutions / minute. At the speeds considered, the bowl must be as light as possible and balanced in order to avoid, as far as possible, unbalances, in particular if its drive means include an air bearing and / or magnetic turbine. It is known, for example from WO-A-94 / 12,286, to connect a bowl to a rotor by means of an interlocking crown capable of radial expansion. It is also known, for example from WO-A-01/66 396 or from US-A-4,473, 188, to use magnetic coupling means between a bowl and the rotor of a turbine. In these devices, the effort to be exerted to decouple the bowl from the rotor must be intense. As soon as these elements are separated, the magnetic coupling force decreases very strongly, so that nothing prevents the tearing movement of the bowl. This results in a risk for an operator to drop a bowl during disassembly, because the resistant force of the magnetic coupling drops very quickly as soon as the bowl is separated from the rotor. However, the fall of such a bowl generally leads to damage to its spraying edge, which degrades the quality of the spraying obtained. In other words, when a bowl falls on the ground, it is not uncommon to have to replace it, while such equipment is, due to the care taken in its realization, expensive. Known devices include one or more magnets together constituting an annular magnetization device. This requires this or these magnets to be large enough to generate an intense magnetic field, which affects the compactness of the projector. In addition, the weight and inertia of the bowl are relatively large, especially in the case where the bowl carries the permanent magnet (s). Finally, the magnets must be subject to a special mechanical assembly so that they do not risk bursting under the effect of centrifugal forces.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention, en proposant un bol de pulvérisation qui peut être aisément entraîné par un rotor prévu à cet effet, grâce à un couplage magnétique efficace, tout en permettant un montage et un démontage aisé du bol, en début et en fin de service.It is to these drawbacks that the invention more particularly intends to remedy, by proposing a spray bowl which can be easily driven by a rotor provided for this purpose, thanks to an effective magnetic coupling, while allowing assembly and disassembly. easy to bowl, at the start and end of service.

Dans cet esprit, l'invention concerne un bol de pulvérisation pour un projecteur rotatif de produit de revêtement, ce bol étant équipé de moyens de couplage magnétique avec un organe d'entraînement en rotation ou avec un boîtier entourant cet organe, caractérisé en ce que ces moyens de couplage magnétique sont aptes à coopérer avec des moyens complémentaires portés par l'organe d'entraînement ou par le boîtier, de telle manière que l'effort de couplage magnétique obtenu a une composante radiale par rapport à l'axe de rotation de ce bol. Grâce à l'invention, l'effort du couplage magnétique obtenu est efficace, alors que les moyens de couplage prévus sur le bol participent au couplage magnétique entre le bol et l'organe d'entraînement ou le boîtier, y compris lors des mouvements de mise en place ou de démontage du bol par rapport au projecteur, ce qui confère une progressivité satisfaisante à l'effort devant être vaincu ou accompagné par l'opérateur à cette occasion.In this spirit, the invention relates to a spray bowl for a rotary sprayer of coating product, this bowl being equipped with magnetic coupling means with a rotary drive member or with a housing surrounding this member, characterized in that these magnetic coupling means are able to cooperate with complementary means carried by the drive member or by the housing, in such a way that the magnetic coupling force obtained has a radial component relative to the axis of rotation of this bowl. Thanks to the invention, the effort of the magnetic coupling obtained is effective, while the coupling means provided on the bowl participate in the magnetic coupling between the bowl and the drive member or the housing, including during movements of installation or dismantling of the bowl relative to the projector, which gives satisfactory progressiveness to the effort to be overcome or accompanied by the operator on this occasion.

En outre, un bol de pulvérisation pour projecteur peut incorporer une ou plusieurs des caractéristiques de l'une des revendications 2 à 8.In addition, a projector spray bowl can incorporate one or more of the features of any of claims 2 to 8.

L'invention concerne également un dispositif de projection de produit de revêtement qui comprend un bol et un organe apte à entraîner ce bol , des moyens de couplage magnétique incluant au moins un aimant permanent étant prévus entre le bol et l'organe précité ou entre le bol et un boîtier entourant cet organe. Ce dispositif est caractérisé en ce que les moyens de couplage sont disposés de telle manière que l'effort de couplage magnétique a une composante radiale par rapport à l'axe de rotation du bol.The invention also relates to a device for spraying a coating product which comprises a bowl and a member capable of driving this bowl, magnetic coupling means including at least one permanent magnet being provided between the bowl and the aforementioned member or between the bowl and a housing surrounding this member. This device is characterized in that the coupling means are arranged in such a way that the magnetic coupling force has a radial component relative to the axis of rotation of the bowl.

De ' façon avantageuse, ces moyens de couplage magnétique comprennent, en outre, au moins un corps magnétique associé à l'aimant et monté sur l'un des deux éléments que sont le bol et l'organe d'entraînement ou le bol et le boîtier, alors que l'autre élément porte au moins une nervure formée dans un matériau magnétique. Dans un tel dispositif, les nervures constituent les pôles induits d'un dispositif de couplage magnétique dont les corps magnétiques associé aux aimants forment les pôles inducteurs.De 'Advantageously, the magnetic coupling means further comprise at least one magnetic body associated with the magnet and mounted on one of the two elements that are the bowl and the driving member or the bowl and housing, while the other element carries at least one rib formed in a magnetic material. In such a device, the ribs constitute the induced poles of a magnetic coupling device whose magnetic bodies associated with the magnets form the inducing poles.

Avantageusement, l'épaisseur de la ou des nervure (s) est sensiblement égale à l'épaisseur des corps magnétiques. De même, lorsque le dispositif comprend plusieurs corps magnétiques et plusieurs nervures, l'écartement relatif de ces nervures est avantageusement sensiblement égal à, ou correspond sensiblement à un multiple ou un sous-multiple de 1 ' écartement relatif d'effort magnétique. Le positionnement et la géométrie de ces nervures sont ainsi adaptés en fonction du positionnement et de la géométrie des masses polaires constituées par les corps magnétiques, pour optimiser l'effet de couplage recherché. Ces nervures permettent une concentration du champ électromagnétique à leur niveau, d'où une amélioration du couplage magnétique obtenu.Advantageously, the thickness of the rib (s) is substantially equal to the thickness of the magnetic bodies. Likewise, when the device comprises several magnetic bodies and several ribs, the relative spacing of these ribs are advantageously substantially equal to, or substantially correspond to a multiple or a sub-multiple of one relative spacing of magnetic force. The positioning and the geometry of these ribs are thus adapted as a function of the positioning and the geometry of the polar masses formed by the magnetic bodies, in order to optimize the desired coupling effect. These ribs allow a concentration of the electromagnetic field at their level, hence an improvement in the magnetic coupling obtained.

Par ailleurs, un dispositif de projection peut incorporer les caractéristiques de l'une des revendications 13 à 21.Furthermore, a projection device can incorporate the features of one of claims 13 to 21.

L'invention concerne enfin une installation de projection de produit de revêtement, qui comprend au moins un dispositif de projection tel que précédemment décrit.The invention finally relates to a coating product spraying installation, which comprises at least one spraying device as described above.

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 cinq modes de réalisation d'un dispositif de projection de produit de revêtement comprenant un bol conforme à l'invention, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels : la figure 1 est une coupe longitudinale de principe d'un projecteur de produit de revêtement conforme à un premier mode de réalisation de l'invention, incorporant un bol conforme à un premier mode de réalisation et faisant partie d'une installation conforme à l'invention ; - la figure 2 est une coupe longitudinale du rotor et une vue de côté du bol du dispositif de la figure 1 ; - la figure 3 est une vue en perspective avec arrachement partiel des éléments représentés à la figure 2 ;The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of five embodiments of a device for spraying a coating product comprising a bowl according to the invention , given solely by way of example and made with reference to the accompanying drawings in which: FIG. 1 is a longitudinal section in principle of a coating product sprayer in accordance with a first embodiment of the invention, incorporating a bowl in accordance with a first embodiment and forming part of an installation in accordance with the invention; - Figure 2 is a longitudinal section of the rotor and a side view of the bowl of the device of Figure 1; - Figure 3 is a perspective view with partial cutaway of the elements shown in Figure 2;

- la figure 8 est une coupe analogue à la figure 7 pour un cinquième mode de réalisation de l'invention. Le dispositif de projection ou projecteur P représenté aux figures 1 à 4 est destiné à être alimenté en produit de revêtement à partir d'une ou plusieurs sources S et déplacé, par exemple avec un mouvement essentiellement vertical représenté par la double flèche Fi, en regard d'objets O à revêtir au sein d'une installation I de revêtement de ces objets. Le projecteur P comprend une turbine dont seul est représenté la partie centrale 1 qui inclut un rotor 11 et qui est entourée par un capotage 2 de protection. Un bol 3 est destiné à être monté sur le rotor 11 et mis en rotation par celui-ci, autour d'un axe X-X', à une vitesse de plusieurs dizaines de milliers de tours par minute, par exemple 80 000 tours/minute, de telle sorte que le produit de revêtement provenant de la source S est pulvérisé en direction d'un objet 0, comme représenté par les flèches F2.- Figure 8 is a section similar to Figure 7 for a fifth embodiment of the invention. The projection device or projector P shown in FIGS. 1 to 4 is intended to be supplied with coating product from one or more sources S and moved, for example with an essentially vertical movement represented by the double arrow Fi, opposite of objects O to be coated within an installation I for coating these objects. The headlight P comprises a turbine of which only the central part 1 is shown which includes a rotor 11 and which is surrounded by a protective cover 2. A bowl 3 is intended to be mounted on the rotor 11 and rotated by the latter, around an axis XX ′, at a speed of several tens of thousands of revolutions per minute, for example 80,000 revolutions / minute, so that the coating material from source S is sprayed towards an object 0, as shown by the arrows F 2 .

Selon un aspect avantageux de l'invention qui n'est pas représenté, le projecteur P peut être de type électrostatique, c'est-à-dire comprendre des moyens de charge électrostatique du produit de revêtement avant ou après que celui-ci a été déchargé à partir de l'arête 31 du bol 3.According to an advantageous aspect of the invention which is not shown, the projector P can be of the electrostatic type, that is to say comprise means for electrostatic charging of the coating product before or after it has been discharged from the edge 31 of the bowl 3.

Le bol 3 est formé de deux pièces, à savoir un moyeu 32 et une partie 33 formant coupelle qui définit une surface 34 d'écoulement et de répartition du produit de revêtement en direction de l'arête 31. Le moyeu 32 est creux et définit un canal longitudinal 35 qui est centré sur un axe X3-X'3 qui est confondu avec l'axe X-X' lorsque le bol 3 est monté sur le rotor 1.The bowl 3 is formed of two parts, namely a hub 32 and a portion 33 forming a cup which defines a surface 34 for flow and distribution of the coating product in the direction of the edge 31. The hub 32 is hollow and defines a longitudinal channel 35 which is centered on an axis X 3 -X ' 3 which coincides with the axis XX' when the bowl 3 is mounted on the rotor 1.

Ce canal 35 communique par des ouvertures radiales 35a avec la surface 34.This channel 35 communicates through radial openings 35a with the surface 34.

Le moyeu 32 constitue une partie mâle du bol 3 qui est destinée à être introduite dans un logement 12 du rotor 11 centré sur l'axe X-X' et qui prolonge un canal 15 d'alimentation du bol 3 en produit de revêtement. Une pipette d'injection 4 peut être prévue dans le canal 15 comme représenté, en traits mixtes uniquement, à la figure 1. Le canal 15 communique avec le logement 12 à travers une zone 16 de diamètre réduit.The hub 32 constitutes a male part of the bowl 3 which is intended to be introduced into a housing 12 of the rotor 11 centered on the axis XX ′ and which extends a channel 15 for supplying the bowl 3 with coating product. An injection pipette 4 can be provided in the channel 15 as shown, in phantom only in Figure 1. The channel 15 communicates with the housing 12 through an area 16 of reduced diameter.

A l'intérieur du logement 12 est disposée une cartouche 5 comportant quatre aimants annulaires 51 à section parallélépipédique et cinq corps magnétiques 52 intercalés entre deux aimants 51 adjacents et disposés de part et d'autre des aimants extérieurs. Les corps 52 peuvent être réalisés dans tout matériau approprié, par exemple en acier. Les aimants 51 ont tous sensiblement la même largeur Isi prise selon une direction radiale par rapport à l'axe X- X' . En revanche, les corps magnétiques 52 ont une largeur .52# mesurée selon la même direction, qui va croissant depuis le côté 53 de la cartouche 5 tourné vers l'extérieur du rotor 1 vers le conduit 15.Inside the housing 12 is disposed a cartridge 5 comprising four annular magnets 51 with parallelepiped section and five magnetic bodies 52 interposed between two adjacent magnets 51 and arranged on either side of the exterior magnets. The bodies 52 can be made of any suitable material, for example steel. The magnets 51 all have substantially the same width Isi taken in a radial direction relative to the axis XX '. On the other hand, the magnetic bodies 52 have a width .52 # measured in the same direction, which increases from the side 53 of the cartridge 5 facing outwards from the rotor 1 towards the conduit 15.

Une cloison étanche et amagnétique 54 est disposée en appui sur les bords 52a des corps 52 faisant saillie par rapport aux aimants 51 en direction de l'axe X-X', cette cloison permettant de protéger, contre les agressions mécaniques et chimiques, les aimants 51.A sealed and non-magnetic partition 54 is disposed in abutment on the edges 52a of the bodies 52 projecting relative to the magnets 51 in the direction of the axis XX ′, this partition making it possible to protect the magnets against mechanical and chemical attack. 51.

La cloison 54 comprend une première partie 54ι cylindrique à base circulaire et centrée sur l'axe X-X' et une seconde partie 542 tronconique et divergente en direction du côté 53 de la cartouche 5, c'est-à-dire en direction du débouché 12a du logement 12 tourné vers l'extérieur du rotor 1.The partition 54 comprises a first cylindrical part 54ι with circular base and centered on the axis XX 'and a second part 54 2 frustoconical and divergent towards the side 53 of the cartridge 5, that is to say in the direction of the outlet 12a of the housing 12 facing the outside of the rotor 1.

La partie 542 de la cloison 54 est prolongée par la surface radiale interne 55x d'une cale 55, le demi angle d'ouverture 55 de la surface tronconique 55χ étant supérieur au demi angle d'ouverture α54 de la surface intérieure de la partie 542.The part 54 2 of the partition 54 is extended by the internal radial surface 55 x of a wedge 55, the half opening angle 55 of the frustoconical surface 55χ being greater than the half opening angle α 54 of the internal surface of part 54 2 .

Les bords 52a des corps 52 qui font saillie par rapport aux éléments 51 sont biseautés pour épouser la forme de la surface externe de la cloison 54.The edges 52a of the bodies 52 which project with respect to the elements 51 are bevelled to conform to the shape of the external surface of the partition 54.

Dans sa partie centrale, la cartouche 5 définit un volume V5 de réception du moyeu 32 du bol 3. Ce volume V5 est délimité, par la surface interne de la partie 542 qui correspond à une surface géométrique S5 tronconique et de demi-angle au sommet α5.In its central part, the cartridge 5 defines a volume V 5 for receiving the hub 32 of the bowl 3. This volume V 5 is delimited by the internal surface of the part 54 2 which corresponds to a geometrical surface S 5 frustoconical and half -angle at the top α 5 .

La surface radiale externe 32a du moyeu 32 est pourvue de quatre nervures 36 qui sont monoblocs avec le moyeu 32, lui même réalisé dans un matériau magnétique, tel que l'acier. Ces nervures forment des collerettes radiales externes par rapport au moyeu 32 et ont, à l'exception de la nervure 36 la plus proche de l'extrémité libre 32b du moyeu 32, leurs surfaces radiales externes respectives tronconiques et inscrites dans une surface géométrique S3 centrée sur l'axe longitudinal X3-X'3, convergente en direction de l'extrémité libre 32b de la partie 32 et de demi angle au sommet α3. La valeur du demi angle α3 est choisie égale à la valeur du demi angle α54. Ainsi, lors de la mise en place du bol 3 sur le rotor 1 et après alignement des axes X-X' et X3-X'3, il est possible de faire coïncider les surfaces S3 et S5, ce qui permet un appui surfacique des surfaces radiales externes 36a de la plupart des nervures ou collerettes 36 sur la cloison 54.The external radial surface 32a of the hub 32 is provided with four ribs 36 which are integral with the hub 32, itself made of a magnetic material, such as steel. These ribs form external radial flanges relative to the hub 32 and, with the exception of the rib 36 closest to the free end 32b of the hub 32, have their respective frustoconical external radial surfaces and inscribed in a geometric surface S 3 centered on the longitudinal axis X 3 -X ' 3 , converging in the direction of the free end 32b of the part 32 and of half angle at the apex α 3 . The value of the half angle α 3 is chosen to be equal to the value of the half angle α 54 . Thus, during the positioning of the bowl 3 on the rotor 1 and after alignment of the axes XX ′ and X 3 -X ′ 3 , it is possible to make the surfaces S 3 and S 5 coincide, which allows surface support external radial surfaces 36a of most of the ribs or flanges 36 on the partition 54.

On atteint alors la position des figures 1 et 4 où les lignes L de champ magnétique dues aux aimants 51 se referment à travers les éléments 52 et 36, en passant également dans les parties principales des éléments 51 et 32.We then reach the position of FIGS. 1 and 4 where the lines L of magnetic field due to the magnets 51 close through the elements 52 and 36, also passing through the main parts of the elements 51 and 32.

Dans cette configuration, l'effort E de couplage magnétique obtenu, lorsque le bol est monté sur le rotor 11 et prêt à tourner, a une composante Ex axiale, non nulle et parallèle à l'axe X-X' de rotation du bol 3 et une composante E2 radiale par rapport à cet axe et également non nulle. Cet effort s'exerce entre les éléments 52 et 36, à travers la cloison 54.In this configuration, the force E of magnetic coupling obtained, when the bowl is mounted on the rotor 11 and ready to turn, has an axial component E x , which is not zero and parallel to the axis XX 'of rotation of the bowl 3 and a component E 2 radial with respect to this axis and also non-zero. This effort is exerted between the elements 52 and 36, through the partition 54.

En pratique, la composante E2 a une intensité supérieure à celle de la composante Ei, ce qui est a rapprocher de la valeur du demi-angle α54 et de la position relative des éléments 52 et 36 en configuration montée du bol 3. Pour amplifier ce phénomène de bouclage magnétique, l'épaisseur e3S des nervures 36 prises parallèlement à l'axe X3-X'3 est sensiblement égale à l'épaisseur e52 des corps magnétiques 52, alors que l'espacement d entre les nervures 36 est sensiblement égal à l'espacement d' de deux corps 52, c'est-à-dire à l'épaisseur e51 d'un aimant 51 prise parallèlement à l'axe X-X' .In practice, the component E 2 has an intensity greater than that of the component Ei, which is to approximate the value of the half-angle α 54 and the relative position of the elements 52 and 36 in the mounted configuration of the bowl 3. To amplify this phenomenon of magnetic looping, the thickness e 3S of the ribs 36 taken parallel to the axis X 3 -X ' 3 is substantially equal to the thickness e 52 of the magnetic bodies 52, while the spacing d between the ribs 36 is substantially equal to the spacing of two bodies 52, that is to say the thickness e 51 of a magnet 51 taken parallel to the axis XX '.

Les aimants 51 sont identiques entre eux, alors que les corps 52 ont tous la même épaisseur, leur largeur prise perpendiculairement à l'axe X-X' étant variable comme expliqué ci-dessus.The magnets 51 are identical to each other, while the bodies 52 all have the same thickness, their width taken perpendicular to the axis XX ′ being variable as explained above.

Au vu de ce qui précède, les nervures ou collerettes circonférentielles 36 participent à la fermeture du champ magnétique créé par les aimants 51 et qui se propage par les corps magnétiques 52.In view of the above, the circumferential ribs or collars 36 participate in the closing of the magnetic field created by the magnets 51 and which is propagated by the magnetic bodies 52.

On note à la figure 4 un léger décalage Δ le long de l'axe X-X' entre les nervures 36 et les corps 52. Ce décalage a pour effet d'exercer sur le moyeu 2 un effort F4/ dû à la composante Ei de l'effort magnétique E dirigée vers l'amont du conduit 15, ce qui a pour effet de plaquer fermement le moyeu 32 à l'intérieur de la cartouche 5 et d' immobiliser ainsi le bol 3 par rapport au rotor 1.Note in FIG. 4 a slight offset Δ along the axis XX 'between the ribs 36 and the bodies 52. This offset has the effect of exerting on the hub 2 a force F 4 / due to the component Ei of the magnetic force E directed upstream of the conduit 15, which has the effect of firmly pressing the hub 32 inside the cartridge 5 and thus immobilizing the bowl 3 relative to the rotor 1.

Lorsqu'on démonte le bol 3 par rapport au reste du projecteur P, on augmente progressivement le décalage Δ et l'effort de couplage magnétique diminue progressivement, ce qui évite les mouvements brusques et les risques pour l'opérateur d'échapper le bol 3. Dans ce cas, les valeurs relatives des composantes Ei et E2 peuvent varier l'une par rapport à 1 ' autre . Dans l'exemple représenté, les nervures 36 sont réalisées par usinage superficiel de la surface 32a du moyeu 32. Selon une variante non représentée de l'invention, ces nervures ou collerettes pourraient être formées par des bagues rapportées sur le moyeu 32.When the bowl 3 is dismantled relative to the rest of the headlight P, the offset Δ is gradually increased and the magnetic coupling force decreases progressively, which avoids sudden movements and the risks for the operator of escaping the bowl 3 In this case, the relative values of the components Ei and E 2 may vary from one another. In the example shown, the ribs 36 are produced by surface machining of the surface 32a of the hub 32. According to a variant not shown of the invention, these ribs or collars could be formed by rings added to the hub 32.

Dans ce premier mode de réalisation, le bol est dépourvu d'aimants, ce qui le rend particulièrement attractif sur le plan économique.In this first embodiment, the bowl is devoid of magnets, which makes it particularly attractive economically.

Un joint torique 6 est monté dans la zone 16 de diamètre réduit et reçoit en appui la partie 54χ de la cloison 54, ce qui permet d'isoler encore plus parfaitement le compartiment de la cartouche 5 qui renferme les aimants par rapport au volume de passage des produits de revêtement et/ou de nettoyage.An O-ring 6 is mounted in the zone 16 of reduced diameter and receives in support the part 54χ of the partition 54, which makes it possible to isolate even more perfectly the compartment of the cartridge 5 which encloses the magnets with respect to the passage volume coating and / or cleaning products.

En variante, la cloison 54 peut ne pas se prolonger jusqu'au niveau de la zone 16, auquel cas le joint 6 vient en appui contre la partie d'extrémité du moyeu 32. On peut alors prévoir que la zone 16 soit légèrement conique afin de faciliter le montage.As a variant, the partition 54 may not extend to the level of the zone 16, in which case the seal 6 abuts against the end portion of the hub 32. It can then be provided that the zone 16 is slightly conical so as to to facilitate assembly.

Selon une variante non représentée de l'invention, des cannelures radiales, de type dents d'engrenage, peuvent être usinées ou rapportées sur la surface radiale interne de la cartouche 5 et sur le moyeu 32, ceci afin d'assurer la tenue du bol, et notamment de limiter le glissement radial et/ou tangentiel de celui-ci par rapport aux aimants, lors des régimes transitoires d'accélération ou de décélération. Dans ce cas, il est nécessaire de prévoir un jeu axial et radial pour le montage avec ces cannelures, de façon à conserver un centrage satisfaisant de la partie conique du bord par rapport aux aimants.According to a variant not shown of the invention, radial grooves, of the gear tooth type, can be machined or attached to the internal radial surface of the cartridge 5 and to the hub 32, this in order to ensure the holding of the bowl , and in particular to limit the radial and / or tangential sliding thereof with respect to the magnets, during transient acceleration or deceleration regimes. In this case, it is necessary to provide an axial and radial clearance for mounting with these grooves, so as to maintain satisfactory centering of the conical part of the edge relative to the magnets.

Dans le second mode de réalisation de l'invention représenté à la figure 5, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 100. Le rotor 111 de ce mode de réalisation forme également un canal 115 d'alimentation en produits de revêtement d'un bol 103 qui comprend un moyeu 132 et une partie 133 pourvue d'une arête 131 de pulvérisation. Des aimants 137 sont montés autour du moyeu 132 et sont séparés deux à deux par un corps magnétique 136 constitué par des nervures ou des bagues rapportées sur le moyeu 132. Une cartouche 105 est montée dans un logement 112 formé au débouché du canal 115 et comprend une bague magnétique pourvue de nervures ou collerettes internes 152 dont l'épaisseur et 1 ' écartement, pris parallèlement à la direction de l'axe X-X' de rotation du rotor 101, sont respectivement égaux à l'épaisseur et à l' écartement des corps 136, pris parallèlement à l'axe central Xιo3-X'ιo3 du bol 103.In the second embodiment of the invention shown in FIG. 5, elements similar to those of the first embodiment bear identical references increased by 100. The rotor 111 of this embodiment also forms a supply channel 115 in coating products of a bowl 103 which comprises a hub 132 and a portion 133 provided with an edge 131 of spray. Magnets 137 are mounted around the hub 132 and are separated in pairs by a magnetic body 136 constituted by ribs or rings attached to the hub 132. A cartridge 105 is mounted in a housing 112 formed at the outlet of the channel 115 and comprises a magnetic ring provided with internal ribs or collars 152 whose thickness and spacing, taken parallel to the direction of the axis XX 'of rotation of the rotor 101, are respectively equal to the thickness and the spacing of the bodies 136, taken parallel to the central axis Xιo3-X'ιo 3 of the bowl 103.

Ce mode de réalisation correspond en pratique au premier mode de réalisation auquel a été appliquée une inversion de structure entre la partie portant les aimants, ici le bol 103, et la partie équipée de nervures constituant les pôles induits de couplage magnétique, ici le rotor 111.This embodiment corresponds in practice to the first embodiment to which a structural inversion has been applied between the part carrying the magnets, here the bowl 103, and the part equipped with ribs constituting the induced poles of magnetic coupling, here the rotor 111 .

Comme précédemment, le volume Vι05 de réception du moyeu 132 dans le logement 112 est divergent en direction du débouché 112a de ce logement et la géométrie des surfaces définissant respectivement ce volume et l'enveloppe externe du moyeu est choisie pour permettre un appui surfacique du moyeu dans la cartouche.As before, the volume Vι 05 for receiving the hub 132 in the housing 112 diverges in the direction of the outlet 112a of this housing and the geometry of the surfaces respectively defining this volume and the external envelope of the hub is chosen to allow surface support of the hub in the cartridge.

Dans le troisième mode de réalisation de l'invention représenté à la figure 6, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 200. Le rotor 211 de ce mode de réalisation forme également un canal 215 d'alimentation en produit de revêtement d'un bol 203 qui comprend un moyeu 232 et une partie 233 pourvue d'une arête de pulvérisation 231. Le rotor 211 est équipé d'un arbre central creux 217 sur lequel sont montés des aimants 251 séparés par des corps magnétiques 252 et au centre duquel se prolonge le canal 215 sous la forme d'un canal 217b de diamètre réduit. Ce canal 217b permet d'alimenter le bol 203 en produits de revêtement et/ou de nettoyage.In the third embodiment of the invention shown in FIG. 6, elements similar to those of the first embodiment bear identical references increased by 200. The rotor 211 of this embodiment also forms a supply channel 215 in coating product of a bowl 203 which comprises a hub 232 and a part 233 provided with a spraying edge 231. The rotor 211 is equipped with a hollow central shaft 217 on which are mounted magnets 251 separated by bodies 252 magnetic and in the center of which extends the channel 215 in the form of a channel 217b of reduced diameter. This channel 217b makes it possible to supply the bowl 203 with coating and / or cleaning products.

Le moyeu 232 forme un logement 212 de réception de l'arbre 217 lorsque le bol 203 est monté sur le rotor 211. On note respectivement X2o3-X'2o3 de l'axe de symétrie du bol 203 et X-X' l'axe de rotation du rotor 211. Ces axes sont confondus lorsque le bol 203 est monté sur le rotor 211.The hub 232 forms a housing 212 for receiving the shaft 217 when the bowl 203 is mounted on the rotor 211. We denote respectively X 2 o3-X ' 2 o3 of the axis of symmetry of the bowl 203 and XX' l ' axis of rotation of rotor 211. These axes coincide when the bowl 203 is mounted on the rotor 211.

La surface interne du moyeu 232 est pourvu de nervures 236 qui s'étendent en direction de l'axe X2o3- '2o3 et sont destinées à être approximativement alignées avec les corps 252 pour constituer les pôles induits par les éléments 251 et 252 lorsqu'un couplage magnétique est obtenu entre les éléments 211 et 203. Comme précédemment, dans ce cas, l'effort de couplage magnétique obtenu a une composante radiale par rapport à l'axe X-X' .The internal surface of the hub 232 is provided with ribs 236 which extend in the direction of the axis X 2 o3- ' 2 o3 and are intended to be approximately aligned with the bodies 252 to constitute the poles induced by the elements 251 and 252 when a magnetic coupling is obtained between the elements 211 and 203. As previously, in this case, the magnetic coupling force obtained has a radial component with respect to the axis XX '.

Une cloison étanche et amagnétique 238 peut être montée en appui sur les nervures 236 et sa surface interne Se est divergente en direction du débouché 212a du logementA watertight and non-magnetic partition 238 can be mounted bearing on the ribs 236 and its internal surface S e is divergent in the direction of the opening 212a of the housing

212, alors que la surface externe des aimants 251 et des corps 252 est convergente en direction de l'extrémité libre 217a de l'arbre 217, ce qui facilite le centrage mécanique des éléments 203 et 207 l'un par rapport à l'autre. Comme précédemment, l'épaisseur des nervures 236 est choisie sensiblement égale à l'épaisseur des corps 252 prise parallèlement à l'axe X-X', leurs écartements relatifs étant également sensiblement égaux.212, while the outer surface of the magnets 251 and of the bodies 252 converge towards the free end 217a of the shaft 217, which facilitates the mechanical centering of the elements 203 and 207 relative to each other . As previously, the thickness of the ribs 236 is chosen to be substantially equal to the thickness of the bodies 252 taken parallel to the axis XX ′, their relative spacings also being substantially equal.

Dans le quatrième mode de réalisation de l'invention représenté à la figure 7, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 300. Le rotor 311 de ce mode de réalisation forme également un canal 315 d'alimentation d'un bol 303 qui comprend un moyeu 332 destiné à être introduit dans un logement 360 défini au centre d'une cartouche annulaire 305 fixée sur la face avant 301a d'un boîtier 301 dans lequel peut tourner le rotor 311 autour de son axe central X-X' . La cartouche 305 comprend trois aimants 351 ainsi que quatre corps ferro-magnétiques 352 en forme de rondelles, ces corps 352 étant destinés à être approximativement alignés avec des nervures radiales externes 336 ménagées sur la surface radiale externe du moyen 332. Les aimants 351 et les rondelles 352 sont circulaires et centrés sur l'axe X-X'. Les polarités Nord et Sud des aimants 351 sont opposées deux à deux, comme dans les modes de réalisation précédents.In the fourth embodiment of the invention shown in FIG. 7, elements similar to those of the first embodiment bear identical references increased by 300. The rotor 311 of this embodiment also forms a supply channel 315 of a bowl 303 which comprises a hub 332 intended to be introduced into a housing 360 defined in the center of an annular cartridge 305 fixed on the front face 301a of a housing 301 in which the rotor 311 can rotate around its central axis XX '. The cartridge 305 comprises three magnets 351 as well as four ferromagnetic bodies 352 in the form of washers, these bodies 352 being intended to be approximately aligned with external radial ribs 336 formed on the external radial surface of the means 332. The magnets 351 and the washers 352 are circular and centered on the axis XX '. The North and South polarities of the magnets 351 are opposite two by two, as in the previous embodiments.

Les nervures 336 pourraient également être rapportées sur le moyeu 332.The ribs 336 could also be attached to the hub 332.

Comme dans les modes de réalisation précédents, un effort magnétique est exercé entre les éléments 305 et 332, les lignes de champ ayant tendance à se refermer à travers les éléments 352 et 336. Cet effort à une composante radiale.As in the previous embodiments, a magnetic force is exerted between the elements 305 and 332, the field lines tending to close through the elements 352 and 336. This force has a radial component.

Par ailleurs, le moyeu 332 est creux et pourvu d'une surface radiale interne 338 qui est tronconique et contre laquelle vient en butée l'extrémité avant tronconique 311a du rotor 311, ce qui permet un emboîtement du bol 303 sur le rotor 311, à la façon d'un cône morse. Compte tenu de la géométrie des éléments 311a, 338 et 336 et du positionnement des éléments 311 et 305 l'un par rapport à l'autre, les éléments 336 et 352 ne sont pas tout à fait alignés en configuration montée du bol, telle que représenté à la figure 7, de sorte que l'effort de couplage magnétique engendré a également une composante dirigée vers la gauche à la figure 7, ce qui tend à plaquer fermement le bol 303 sur le rotor 311. Dans cette configuration, un entrefer cylindrique à base circulaire existe entre le jeu d'aimants 351 et les nervures 336.Furthermore, the hub 332 is hollow and provided with an internal radial surface 338 which is frustoconical and against which abuts the frustoconical front end 311a of the rotor 311, which allows the bowl 303 to be fitted onto the rotor 311, the way of a walrus cone. Given the geometry of the elements 311a, 338 and 336 and the positioning of the elements 311 and 305 relative to one another, the elements 336 and 352 are not completely aligned in the mounted configuration of the bowl, such as represented in FIG. 7, so that the magnetic coupling force generated also has a component directed towards the left in FIG. 7, which tends to press the bowl 303 firmly onto the rotor 311. In this configuration, a cylindrical air gap with a circular base exists between the set of magnets 351 and the ribs 336.

Il est aisé d'ajuster la valeur de l'effort de fixation du bol en fonction de sa taille, de son poids et de sa vitesse de rotation, en jouant sur le nombre d'aimants de la cartouche 305. Les avantages particuliers de ce mode de réalisation sont la faible masse des parties tournantes et la simplicité de réalisation. Dans le cinquième mode de réalisation de l'invention représenté à la figure 8, les éléments analogues à ceux du premier mode de réalisation porte des références identiques augmentées de 400. Les aimants 451 et les corps magnétiques 452 sont disposés avec une configuration tronconique, le bol 403 ayant, quant à lui, un moyeu 432 dont la surface externe est tronconique et convergente vers l'arrière du rotor 411, cette surface étant équipée de nervures 436 destinées à être, approximativement au moins, en alignement avec les corps 452. La coopération des éléments 451 et 452, d'une part, et des nervures 436, d'autre part, assure à la fois la fixation magnétique et le centrage mécanique du bol- dans l'extrémité avant 411a du rotor 411 qui est en forme d'arbre centré sur son axe de rotation X-X' .It is easy to adjust the value of the bowl fixing force as a function of its size, its weight and its speed of rotation, by varying the number of magnets of the cartridge 305. The particular advantages of this embodiment are the low mass of the rotating parts and the simplicity of implementation. In the fifth embodiment of the invention shown in FIG. 8, elements similar to those of the first embodiment bear identical references increased by 400. The magnets 451 and the magnetic bodies 452 are arranged in a frustoconical configuration, the bowl 403 having, meanwhile, a hub 432 whose outer surface is frustoconical and converging towards the rear of the rotor 411, this surface being equipped with ribs 436 intended to be, approximately at least, in alignment with the bodies 452. The cooperation of the elements 451 and 452, on the one hand, and ribs 436, on the other hand, ensures both the magnetic fixing and the mechanical centering of the bowl- in the front end 411a of the rotor 411 which is in the form of a 'shaft centered on its axis of rotation XX'.

Un avantage de ce mode de réalisation est qu'il permet d'obtenir un effort de fixation calibré en intensité en supprimant un éventuel effet de « crantage magnétique » qui peut déplaire à l'opérateur. La conicité des aimants 451 est choisie suffisante pour que les entrefers successifs soient supérieurs à la distance d'attraction, jusqu'à la position montée du bol 403, la qualité des aimants et la précision du montage permettant de définir cette conicité. Ce mode de réalisation présente également l'avantage d'une bonne compacité selon la direction de l'axe X-X' et d'une possibilité de pré-positionnement du bol 403 dans l'extrémité avant 411a du rotor 411 lors de son montage.An advantage of this embodiment is that it makes it possible to obtain a fixing force calibrated in intensity by eliminating a possible "magnetic catch" effect which may displease the operator. The taper of the magnets 451 is chosen to be sufficient for the successive air gaps to be greater than the attraction distance, up to the mounted position of the bowl 403, the quality of the magnets and the precision of the assembly making it possible to define this taper. This embodiment also has the advantage of good compactness in the direction of the axis XX 'and of a possibility of pre-positioning the bowl 403 in the front end 411a of the rotor 411 during assembly.

Selon une première variante non représentée de l'invention, l' écartement relatif des nervures 36 et équivalentes peut être choisi égal à un sous-multiple de la largeur l_sι des aimants 51, c'est-à-dire de l' écartement relatif des corps magnétiques 52 et équivalent. En effet, un alignement de certaines nervures 36 ou équivalentes avec les corps 52 et équivalents demeurent possible, certaines autres nervures se trouvant alors en regard des aimants 51. Ces autres nervures sont alors peu fonctionnelles pour le couplage magnétique recherché. Ceci est applicable à tous les modes de réalisation envisagés.According to a first variant not shown of the invention, the relative spacing of the ribs 36 and the like can be chosen equal to a submultiple of the width l_sι of the magnets 51, that is to say of the relative spacing of the magnetic bodies 52 and equivalent. Indeed, an alignment of certain ribs 36 or equivalent with the bodies 52 and the like remains possible, certain other ribs then being located opposite the magnets 51. These other ribs are then not very functional for the desired magnetic coupling. This is applicable to all the embodiments envisaged.

Selon une autre variante non représentée de l'invention, l' écartement d peut être égal à un multiple de l' écartement d' des corps 52. Dans ce cas, certains corps 52 sont en regard d'une zone intermédiaire entre deux nervures 36 ou équivalentes. Ceci peut également être appliqué à tous les modes de réalisation envisagés. L'invention a été représentée avec des bols 3, 103 ou 203 bipartites. Elle est également applicable avec un bol dont la partie de répartition du produit et le moyeu sont monoblocs. La représentation des bols 303 et 403 est très schématique. L'invention est applicable indépendamment de la nature exacte du produit , projeté, liquide ou pulvérulent, hydrosoluble ou non. L'invention fonctionne avec des projecteurs électrostatiques ou non. Les caractéristiques techniques des modes de réalisation décrits peuvent être combinées entre elles dans le cadre de la présente invention.According to another variant not shown of the invention, the spacing d can be equal to a multiple of the spacing of the bodies 52. In this case, certain bodies 52 are opposite an intermediate zone between two ribs 36 or equivalent. This can also be applied to all the embodiments envisaged. The invention has been shown with 3, 103 or 203 bipartite bowls. It is also applicable with a bowl, the product distribution part and the hub are one-piece. The representation of bowls 303 and 403 is very schematic. The invention is applicable regardless of the exact nature of the product, sprayed, liquid or pulverulent, water-soluble or not. The invention works with electrostatic headlights or not. The technical characteristics of the described embodiments can be combined with one another within the scope of the present invention.

Quel que soit le mode de réalisation considéré, les éléments magnétiques, qu'ils s'agissent des aimants ou des nervures associées, sont, une fois le bol monté sur le rotor, situés à l'intérieur des logements 12, 112, 212, 360 ou équivalents, ce qui induit trois avantages supplémentaires par rapport à une construction telle que connue de WO-A-01/162396, à savoir : - une bonne compacité axiale qui est importante car il convient de réduire le plus possible la dimension axiale d'un pulvérisateur pour atteindre correctement des zones d'un objet à revêtir dont le rayon de courbure faible, telles que les détourages de portes de carrosserie de véhicule automobile. Ceci permet d'améliorer la manœuvrabilité d'un robot et d'un pulvérisateur incorporant l'invention et de réduire le moment résistant sur le poignet .Whatever the embodiment considered, the magnetic elements, whether magnets or associated ribs, are, once the bowl is mounted on the rotor, located inside the housings 12, 112, 212, 360 or equivalent, which induces three additional advantages compared to a construction as known from WO-A-01/162396, namely: - good axial compactness which is important because it is necessary to reduce the axial dimension of a sprayer as much as possible in order to correctly reach areas of an object to be coated with a small radius of curvature, such as car door trim. This improves the maneuverability of a robot and a sprayer incorporating the invention and reduces the resistant moment on the wrist.

- des pertes de peinture minimisées du fait de la compacité axiale obtenue pour le projecteur. Ceci induit également une consommation moindre de produits de rinçage lors des changements des produits de revêtement.- minimized paint losses due to the axial compactness obtained for the projector. This also induces a lower consumption of rinse aid when changing the coating products.

- une protection améliorée des aimants contre les chocs, ces aimants étant fragiles par construction. L'invention est applicable indépendamment du nombre exact d'aimant (s) et de nervure (s) utilisées, le nombre de nervure (s) étant, en pratique, adapté au nombre d'aimant (s) . - Improved protection of the magnets against shocks, these magnets being fragile by construction. The invention is applicable regardless of the exact number of magnet (s) and rib (s) used, the number of rib (s) being, in practice, adapted to the number of magnet (s).
