Description

La présente invention concerne un dispositif de support d'une pièce destinée à être peinte, du type comprenant une pièce destinée à être peinte, comprenant au moins un masque de protection destiné à couvrir une zone de la pièce, le masque de protection comprenant une face de contact destinée à être appliquée contre la zone de la pièce devant être laissée vierge.The present invention relates to a device for supporting a part intended to be painted, of the type comprising a part intended to be painted, comprising at least one protective mask intended to cover an area of the part, the protective mask comprising a face contact intended to be applied against the area of the part to be left blank.

Un tel dispositif sert par exemple pour le support de becquets, de peaux de pare-chocs de véhicule automobile, ou d'autres pièces de carrosseries devant être peintes sur une ligne de production.Such a device serves for example for the support of spoilers, bumper skins of a motor vehicle, or other parts of bodies to be painted on a production line.

Afin d'assurer une bonne fixation du pare-chocs sur un véhicule automobile ou de permettre la fixation d'éléments rapportés, il convient de laisser les zones de fixation de la pièce de carrosserie non peinte, car la peinture empêche le maintien de l'adhésif de type ruban ou le bon collage par dépôt de colle utilisé sur la pièce.In order to ensure a good fixation of the bumper on a motor vehicle or to allow the attachment of inserts, it is advisable to leave the fixing areas of the body part unpainted, because the paint prevents the maintenance of the ribbon type adhesive or the good glue adhesive bonding used on the piece.

L'invention concerne également une structure métallique (mécanique ou moulée) comprenant un tel dispositif de support, une installation comprenant une pièce à peindre accostée sur une telle structure et le procédé relatif à l'invention.The invention also relates to a metal structure (mechanical or molded) comprising such a support device, an installation comprising a piece to be painted abutted on such a structure and the method relating to the invention.

Des dispositifs de support du type précité sont connus, par exemple du document US6387183 . Cependant, la partie du dispositif de support visant à protéger la zone destinée à rester vierge de peinture de la pièce à peindre est située à distance de la pièce. Il est donc possible d'avoir des projections, non voulues sur la zone de la pièce destinée à rester vierge, ce qui entraîne ensuite des problèmes d'adhésion des pièces rapportées collées sur la zone non peinte.Support devices of the aforementioned type are known, for example from the document US6387183 . However, the part of the support device to protect the area to remain virgin paint of the room to be painted is located away from the room. It is therefore possible to have projections, unwanted on the area of the room to remain virgin, which then causes problems adhesion of inserts glued to the unpainted area.

De plus, l'application de peinture doit être faite par un appareil positionné très exactement. Si celui-ci est décalé, la variation d'angle entre le bord du masque de protection et la pièce entraîne un décalage de la zone qui est protégée par le masque de protection, et donc un mauvais positionnement des pièces rapportées sur la pièce peinte.In addition, the application of paint must be made by a device positioned exactly. If it is shifted, the angle variation between the edge of the protective mask and the part causes a shift of the area which is protected by the protective mask, and thus a bad positioning of the inserts on the painted part.

Un but de l'invention est donc d'améliorer l'efficacité du masque de peinture.An object of the invention is therefore to improve the efficiency of the paint mask.

A cet effet, l'invention a pour objet un dispositif de support, dans lequel le masque de protection comprend un logement rempli d'un matériau de protection, le matériau formant la face de contact du masque de protection.For this purpose, the subject of the invention is a support device, in which the protective mask comprises a housing filled with a protective material, the material forming the contact face of the protective mask.

  • berthing of the area of the part intended to remain blank of paint on the protective mask;
  • painting application on the piece; and
  • removing the piece from the support device.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, dans lesquels :

  • la figure 1 est une vue de côté d'une installation de peinture, comprenant un dispositif de support selon l'invention ;
  • les figures 2 et 3 sont des vues de côté de différents modes de réalisation d'un dispositif de support selon l'invention.
Other features and advantages of the invention will appear on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
  • the figure 1 is a side view of a paint installation, comprising a support device according to the invention;
  • the Figures 2 and 3 are side views of different embodiments of a support device according to the invention.

La figure 1 illustre une installation de peinture 10 d'une pièce 12, par exemple de carrosserie automobile, devant être peinte.The figure 1 illustrates a painting installation 10 of a part 12, for example of automobile body, to be painted.

Une telle pièce 12 de carrosserie comprend, de façon classique, une face externe 14 destinée à former une surface extérieure d'un véhicule automobile et une face interne 16, opposée à la face externe 14, et formant l'interface de montage de la pièce 12 de carrosserie sur le véhicule automobile (non représenté). La face externe 14 formant une partie visible du véhicule, il convient que celle-ci ait une apparence satisfaisante. A cet effet, la face externe 14 de la pièce 12 de carrosserie est peinte. Au contraire, afin d'assurer une bonne fixation de la pièce 12 sur un véhicule automobile ou de permettre la fixation d'éléments rapportés sur la face interne 16, il convient de laisser des zones 18 de la face interne 16 de la pièce 12 de carrosserie non peinte.Such a body part 12 comprises, in a conventional manner, an outer face 14 intended to form an outer surface of a motor vehicle and an inner face 16, opposite to the outer face 14, and forming the mounting interface of the part 12 of bodywork on the motor vehicle (not shown). The outer face 14 forming a visible part of the vehicle, it should be that it has a satisfactory appearance. For this purpose, the outer face 14 of the body part 12 is painted. On the contrary, in order to ensure good attachment of the part 12 to a motor vehicle or to allow the attachment of inserts on the inner face 16, it is appropriate to leave areas 18 of the inner face 16 of the part 12 of unpainted bodywork.

L'installation de peinture 10 comporte au moins la pièce 12 destinée à être peinte et une structure métallique 20.The paint installation 10 comprises at least the part 12 intended to be painted and a metal structure 20.

La structure métallique 20 est par exemple une balancelle.The metal structure 20 is for example a swing.

La structure métallique 20 comprend une ossature 22 et au moins un dispositif de support 24.The metal structure 20 comprises a framework 22 and at least one support device 24.

L'ossature 22 est par exemple un mât 26, avantageusement d'une hauteur comprise entre 1 m et 2m, et s'étendant à partir d'un pied 28 disposé sur le sol.The frame 22 is for example a mast 26, preferably a height between 1 m and 2m, and extending from a foot 28 disposed on the ground.

Le mât 26 comporte par exemple une pluralité d'éléments 30 de réceptions servant à soutenir la pièce 12 par l'intermédiaire du dispositif de support 24, et permettant un réglage en hauteur de la pièce 12.The mast 26 comprises for example a plurality of reception elements 30 for supporting the workpiece 12 via the support device 24, and allowing a height adjustment of the workpiece 12.

Les éléments de réception 30 sont disposés à intervalles de longueur réguliers sur le mât 26, depuis son extrémité supérieure jusqu'à une distance adéquate du sol, afin d'éviter que la pièce 12 ne touche le sol lorsqu'elle est maintenue par l'élément de réception 30 le plus proche du sol.The receiving elements 30 are arranged at regular length intervals on the mast 26, from its upper end to a suitable distance from the ground, to prevent the piece 12 from touching the ground when it is held by the receiving element 30 closest to the ground.

Les éléments de réception 30 du mât 26 sont de plus disposés en regard d'au moins une buse pulvérisatrice 32 de peinture.The receiving elements 30 of the mast 26 are further arranged facing at least one spray nozzle 32 of paint.

La pluralité d'éléments de réception 30 permet de disposer plusieurs pièces 12 sur le mât 26 afin de les peindre simultanément.The plurality of receiving elements 30 makes it possible to have several pieces 12 on the mast 26 in order to paint them simultaneously.

Le dispositif de support 24 comprend par exemple un ou plusieurs bras 34 fixés de façon amovible sur un élément de réception 30 et agencés pour maintenir une pièce 12 selon l'orientation souhaitée. Le dispositif de support 24 permet ainsi de raccorder une pièce 12 à un élément quelconque de réception 30.The support device 24 comprises for example one or more arms 34 removably attached to a receiving member 30 and arranged to hold a workpiece 12 in the desired orientation. The support device 24 thus makes it possible to connect a part 12 to any receiving element 30.

Pour déplacer en hauteur une pièce 12, le dispositif de support 24 peut être désolidarisé de l'élément de réception 30 sur lequel il a été fixé et être solidarisé à un autre élément de réception 30 à une hauteur différente.To move a workpiece 12 upwards, the support device 24 can be detached from the receiving element 30 on which it has been fixed and be secured to another receiving element 30 at a different height.

Le dispositif de support 24 est agencé de telle sorte qu'une zone à peindre 36 de la pièce 12 soit disposée en regard de la buse 32 de peinture lorsque ladite pièce 12 est fixée sur le dispositif de support 24.The support device 24 is arranged such that an area to be painted 36 of the part 12 is arranged facing the paint nozzle 32 when said part 12 is fixed on the support device 24.

En référence aux figures 2 et 3, la pièce 12 comprend au moins une zone destinée à recevoir la peinture 36, et au moins une zone de ladite pièce devant rester non peinte 18. Comme décrit précédemment, la zone à peindre 36 est par exemple formée par tout ou partie de la face externe 14 d'une pièce 12 de carrosserie et la zone à protéger 18 est formée par tout ou partie de la face interne 16 de la pièce 12 de carrosserie.With reference to Figures 2 and 3 the part 12 comprises at least one zone intended to receive the paint 36, and at least one zone of said part to remain unpainted 18. As described above, the zone to be painted 36 is for example formed by all or part of the face external 14 of a body part 12 and the area to be protected 18 is formed by all or part of the inner face 16 of the body part 12.

Le dispositif de support 24 comprend également, à cet effet, au moins un masque de protection 38. Le masque 38 est solidaire d'un bras du dispositif de support 24 d'une part, et d'autre part est destiné à être appliquée contre et à couvrir la zone à protéger 18, afin que celle-ci ne soit pas exposée au nuage de peinture issu de la buse 32. Le masque 38 comprend donc une face de contact 40 destinée à être placée contre la zone à protéger 18. Le contact entre le maque de protection 38 et la pièce 12 est un contact étanche. Ainsi, le masque 38 forme une barrière entre la zone à protéger 18 et le nuage de peinture, ce qui permet de peindre la pièce 12 sans avoir à éviter précisément la zone à protéger 18 tout en laissant cette zone à protéger 18 non peinte à l'issu du cycle de peinture.The support device 24 also comprises, for this purpose, at least one protective mask 38. The mask 38 is integral with an arm of the support device 24 on the one hand, and on the other hand is intended to be applied against and to cover the area to be protected 18 so that it is not exposed to the cloud of paint coming from the nozzle 32. The mask 38 thus comprises a contact face 40 intended to be placed against the zone to be protected. contact between the protective mask 38 and the part 12 is a sealed contact. Thus, the mask 38 forms a barrier between the zone to be protected 18 and the cloud of paint, which makes it possible to paint the part 12 without having to precisely avoid the zone to be protected 18 while leaving this area to be protected 18 unpainted at the same time. 'from the painting cycle.

Le masque 38 comprend un logement 42 rempli d'un matériau de protection 43.The mask 38 comprises a housing 42 filled with a protective material 43.

Le logement est par exemple formé par une goulotte 44 présentant une cavité 46 tournée vers la zone de la pièce devant être laissée vierge 18, sensiblement à l'opposé du bras du dispositif de support 24. La goulotte 44 peut être en fil d'acier ou inox (voir figure 2) ou en feuille de tôle (voir figure 3).The housing is for example formed by a chute 44 having a cavity 46 facing the zone of the part to be left blank 18, substantially opposite the arm of the support device 24. The chute 44 may be made of steel wire or stainless steel (see figure 2 ) or sheet metal (see figure 3 ).

La goulotte 44 peut être formée par un ensemble de pièces profilées laser ou un assemblage de pièces profilées par cintrage numérique. Ainsi la goulotte 44 est très précisément de la forme et de la taille de la zone à ne pas peindre 18, qui est par exemple une zone de fixation, ce qui permet de définir précisément la forme et l'emplacement de la zone de fixation et par la suite de bien positionner une pièce à coller.The trough 44 may be formed by a set of laser profiled parts or an assembly of parts profiled by digital bending. Thus the chute 44 is very precisely the shape and size of the area to be painted 18, which is for example a fixing area, which allows to precisely define the shape and location of the fixing area and subsequently position a piece to stick.

Le matériau de protection 43 est par exemple une résine ou un joint. Le matériau de protection 43 est par exemple ignifugé et/ou résistant à une température supérieure à 80°C. Le matériau de protection 43 dépasse de la cavité 46 de la goulotte 44 vers la pièce à peindre 12 et forme la face de contact 40 du matériau.The protective material 43 is for example a resin or a seal. The protective material 43 is for example fireproof and / or resistant to a temperature above 80 ° C. The protective material 43 protrudes from the cavity 46 of the trough 44 towards the workpiece 12 and forms the contact face 40 of the material.

Dans un mode de réalisation de l'invention, le matériau de protection 43 est amovible par rapport à la goulotte 44.In one embodiment of the invention, the protective material 43 is removable with respect to the chute 44.

Le masque 38 n'est pas nécessairement continu et peut comprendre une ou plusieurs ouvertures (non représentées) permettant d'exposer à la peinture une ou plusieurs parties dans la zone à protéger 18. En variante, le masque 38 peut être réalisé en plusieurs parties, chaque partie étant appliquée contre une zone à protéger 18.The mask 38 is not necessarily continuous and may include one or more openings (not shown) for exposing one or Several parts in the zone to be protected 18. In a variant, the mask 38 may be made in several parts, each part being applied against an area to be protected 18.

Un procédé de peinture d'une pièce 12 au moyen de l'installation de peinture 10 selon l'invention décrite ci-dessus va maintenant être décrit.A method of painting a workpiece 12 by means of the paint installation 10 according to the invention described above will now be described.

Initialement, on dispose d'une ossature métallique 20 pourvue d'une pluralité d'éléments de réception 30.Initially, there is a metal frame 20 provided with a plurality of receiving elements 30.

Le masque 38 est fixé sur l'ossature métallique 20 par l'intermédiaire du dispositif de support 24. Le dispositif de support 24 se fixe par l'une de ses extrémités dans un élément de réception 30.The mask 38 is fixed on the metal framework 20 via the support device 24. The support device 24 is fixed at one of its ends in a receiving element 30.

On accroche la pièce 12 sur le dispositif de support 24, ce qui vient mettre en contact le masque 38 sur la zone à protéger 18, par un contact étanche. Les dimensions du dispositif de support 24 sont agencées pour que lorsque la pièce 12 est accrochée sur le dispositif de support 24, le masque 38 se place automatiquement et précisément sur la zone à protéger 18.The part 12 is attached to the support device 24, which comes into contact with the mask 38 on the zone to be protected 18, by a sealed contact. The dimensions of the support device 24 are arranged so that when the piece 12 is hooked on the support device 24, the mask 38 is placed automatically and precisely on the area to be protected 18.

L'opération de peinture est effectuée par l'intermédiaire de la buse 32.The painting operation is carried out via the nozzle 32.

Entre chaque opération de peinture, la pièce 12 venant d'être peinte est retirée du dispositif de support 24, puis remplacée par une nouvelle pièce 12 destinée à être peinte selon le même procédé. Comme indiqué précédemment, plusieurs pièces 12 peuvent être peintes simultanément en les fixant à différents éléments de réception 30 de la structure métallique 20. Dans ce cas, il est entendu qu'autant de dispositifs de support 24 sont également fixés à ces éléments de réception 30.Between each painting operation, the newly painted part 12 is removed from the support device 24 and then replaced by a new part 12 intended to be painted according to the same method. As previously indicated, several pieces 12 can be painted simultaneously by attaching them to different receiving elements 30 of the metal structure 20. In this case, it is understood that as many support devices 24 are also attached to these receiving elements 30 .

Au bout d'un nombre prédéterminé de cycles de peinture comme décrits ci-dessus, le matériau de protection 43 est retiré du masque 38. Le matériau de protection 43 est par exemple retiré du masque 38 au bout d'une centaine de cycles de peinture.After a predetermined number of paint cycles as described above, the protective material 43 is removed from the mask 38. The protective material 43 is for example removed from the mask 38 after a hundred paint cycles .

Par la suite, la structure métallique 20 est nettoyée à haute pression pour retirer la peinture accumulée. On remet par la suite le matériau de protection 43, qui aurait été dégradé par cette étape de nettoyage à haute pression.Subsequently, the metal structure 20 is cleaned at high pressure to remove the accumulated paint. Subsequently, the protective material 43, which has been degraded by this high-pressure cleaning step, is returned.

En variante, le dispositif de support 24 pourrait être retiré de l'ossature 26 lors de l'étape de nettoyage de la structure métallique 20.Alternatively, the support device 24 could be removed from the frame 26 during the step of cleaning the metal structure 20.
