Abstract
Description
La présente invention a pour objet des perfectionnements apportés aux installations de revêtement par pulvérisation.The present invention relates to improvements made to spray coating installations.
On utilise à l'heure actuelle des installations de revêtement et plus particulièrement des installations de revêtement par procédé électrostatique comportant des dispositifs de pulvérisation qui se présentent généralement sous la forme d'un disque circulaire ou bol assurant la distribution de la matière de revêtement amenée à sa surface, la pièce devant être pourvue du revêtement se déplaçant suivant une trajectoire déterminée, généralement en forme d'arc de cercle autour de la tête de pulvérisation et dans le plan de rotation de cette dernière.Coating installations and more particularly electrostatic coating installations are currently used comprising spraying devices which are generally in the form of a circular disc or bowl ensuring the distribution of the coating material brought to its surface, the part to be provided with the coating moving along a determined trajectory, generally in the form of an arc of a circle around the spray head and in the plane of rotation of the latter.
La mise en oeuvre de ces systèmes de pulvérisation présente un certain nombre de difficultés notamment lorsque l'on veut réaliser une pulvérisation sur toutes les faces de l'objet à revêtir.The implementation of these spraying systems presents a certain number of difficulties, in particular when it is desired to spray on all the faces of the object to be coated.
Généralement, dans de telles installations, les objets devant être munis du revêtement notamment par pulvérisation électro-statique à l'aide d'une tête de pulvérisation, se déplacent dans l'installation en étant transportés par un convoyeur, de façon à pouvoir être aménes successivement devant la tête de pulvérisation. Pour assurer une pulvérisation sur toute la surface de la pièce et en particulier sur les deux faces opposées de celle-ci quand elle se présente sous la forme d'un panneau plan, il est nécessaire de prévoir des trajectoires de convoyage plus ou moins compliquées.Generally, in such installations, the objects to be provided with the coating, in particular by electrostatic spraying using a spray head, move in the installation by being transported by a conveyor, so that they can be brought successively in front of the spray head. To ensure spraying over the entire surface of the part and in particular on the two opposite faces of the latter when it is in the form of a flat panel, it is necessary to provide more or less complicated conveying paths.
On a ainsi envisagé d'utiliser une trajectoire en forme de boucle, amenant successivement les deux faces de l'objet à revêtir devant une tête de pulvérisation unique. Cependant, dans ce cas, il faut prévoir un retournement de la pièce de manière à obtenir ce revêtement sur les deux faces, ce qui oblige à concevoir des systèmes de crochet rotatifs sur l'installation de convoyage.It has thus been envisaged to use a loop-shaped trajectory, successively bringing the two faces of the object to be coated in front of a single spray head. However, in this case, it is necessary to provide for a reversal of the part so as to obtain this coating on the two sides, which requires the design of rotating hook systems on the conveyor system.
Dans d'autres installations, on utilise deux têtes de pulvérisation et l'objet à revêtir est amené successivement devant chacune de ces têtes de pulvérisation, grâce à un transporteur qui présente une trajectoire à double boucle inversée, ce qui permet de traiter successivement les deux faces opposées de la pièce.In other installations, two spray heads are used and the object to be coated is brought successively in front of each of these spray heads, by means of a conveyor which has an inverted double loop trajectory, which makes it possible to successively treat the two opposite sides of the room.
Ainsi il résulte de l'état antérieur de la technique que pour traiter des pièces sur leurs deux faces et notamment des pièces planes, il est nécessaire :
- soit de prévoir au moins deux moyens de pulvérisation (par exemple deux têtes de pulvérisation électro-statiques devant lesquelles sont amenées successivement les deux faces opposées de la pièce à traiter ;
- soit de prévoir des crochets rotatifs auxquels sont suspendues les pièces à traiter, ces crochets se déplaçant sur les systèmes de convoyage.Thus it follows from the prior art that to treat parts on their two faces and in particular flat parts, it is necessary:
- Either to provide at least two spraying means (for example two electro-static spray heads in front of which are brought successively the two opposite faces of the part to be treated;
- Or to provide rotary hooks to which the parts to be treated are suspended, these hooks moving on the conveying systems.
Ces installations connues sont donc peu pratiques, coûteuses, entraînent un gaspillage d'espace et sont difficilement utilisables pour traiter des pièces de grandes dimensions devant être suspendues en au moins deux points sur les crochets des installations de convoyage.These known installations are therefore impractical, costly, cause a waste of space and are difficult to use for treating large parts which have to be suspended at at least two points on the hooks of the conveying installations.
En conséquence, la présente invention se propose d'apporter une installation ne présentant pas les inconvénients des installations selon la technique antérieure rappelée ci-dessus.Consequently, the present invention proposes to provide an installation which does not have the drawbacks of the installations according to the prior art recalled above.
Cette invention a donc pour objet des perfectionnements apportés aux dispositifs de revêtement par pulvérisation à l'aide d'un moyen de pulvérisation assurant la projection et la distribution de la matière de revêtement et devant lequel se déplacent les objets à traiter qui sont transportés par un système de convoyage, ces perfectionnements étant caractérisés en ce que le parcours des pièces à traiter le long dudit système de convoyage est conçu de manière qu'une tête de pulvérisation unique puisse traiter alternativement les deux faces opposées d'une pièce et en ce que ledit parcours comporte :
- une première partie amenant la première face de chaque pièce en regard du moyen de pulvérisation, sur l'un des côtés de ce dernier.
- une seconde partie ou détour le long de laquelle les pièces en déplacement subissent une rotatation de 360° et
- une troisième partie assurant la présentation des pièces au moyen de pulvérisation, celui-ci effectuant alors le dépôt de la matière de revêtement sur la deuxième face de ladite pièce.This invention therefore relates to improvements made to spray coating devices using a spray means ensuring the projection and distribution of the coating material and in front of which move the objects to be treated which are transported by a conveyor system, these improvements being characterized in that the path of the parts to be treated along of said conveying system is designed so that a single spray head can alternately treat the two opposite faces of a part and in that said path comprises:
- A first part bringing the first face of each part opposite the spraying means, on one of the sides of the latter.
- a second part or detour along which the moving parts undergo a 360 ° rotation and
- A third part ensuring the presentation of the parts by spraying, the latter then effecting the deposition of the coating material on the second face of said part.
Selon un exemple de réalisation de l'invention la seconde partie ou détour du parcours comprend :
- une première et une seconde courbes chacune de 90°, orientées dans le même sens, suivies d'une trajectoire sensiblement rectiligne et parallèle à ladite première partie cette trajectoire étant située à l'extérieur de l'installation de pulvérisation ;
- une troisième et une quatrième courbes, chacune de 90°, orientées dans le même sens et à l'extérieur de l'installation de pulvérisation.According to an exemplary embodiment of the invention, the second part or detour of the route comprises:
- a first and a second curve each of 90 °, oriented in the same direction, followed by a substantially rectilinear trajectory and parallel to said first part, this trajectory being located outside the spraying installation;
- a third and a fourth curve, each 90 °, oriented in the same direction and outside the spraying installation.
Selon un mode de réalisation préféré de la présente invention, les deux parties de la trajectoire du système de convoyage dans la zone de revêtement par pulvérisation peuvent être rectilignes ou présenter une légère courbure, en regard du moyen de pulvérisation, cette courbure étant centrée sur ce moyen.According to a preferred embodiment of the present invention, the two parts of the trajectory of the conveyor system in the spray coating zone may be straight or have a slight curvature, opposite the spraying means, this curvature being centered on this way.
Selon l'invention la présentation des pièces devant le moyen de pulvérisation peut s'effectuer soit en continue soit par arrêt cadencé de ces pièces c'est à dire selon un déplacement pas à pas.According to the invention, the presentation of the parts in front of the spraying means can be carried out either continuously or by timed stopping of these parts, that is to say according to a stepwise movement.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent un mode de réalisation donné à titre d'exemple, dépourvu de tout caractère limitatif. Sur les dessins :
- - La figure 1 représente une installation de revêtement électrostatique selon l'invention, en coupe axiale verticale et
- - La figure 2 est une vue en plan et coupe horizontale de la figure 1 sur laquelle on a représenté la trajectoire des pièces à traiter par l'installation selon l'invention.
- - Figure 1 shows an electrostatic coating installation according to the invention, in vertical axial section and
- - Figure 2 is a plan view and horizontal section of Figure 1 in which there is shown the path of the parts to be treated by the installation according to the invention.
En se référant au dessin, on voit qu'une installation selon la présente invention se présente sous la forme d'une enceinte 10 ou cabine, à l'intérieur de laquelle s'effectue le revêtement des pièces par pulvérisation. Dans cet exemple de réalisation non limitatif on utilise un système de pulvérisation électro-statique, qui comporte une tête du type disque ou bol circulaire, assurant la distribution de la matière du revêtement. Cette tête de pulvérisation 12 est de type bien connu et par conséquent elle ne sera pas décrite ici. Comme on le voit sur le dessin, la tête de pulvérisation est montée à l'extrémité d'un canon support 14 qui peut se déplacer axialement par l'intermédiaire d'un dispositif classique de chaîne sans fin 16 de façon à imprimer à la tête 12 un mouvement de balayage vertical alternatif à course réglable en fonction de la hauteur des pièces à traiter. Bien entendu un tel système peut être remplacé par tout moyen équivalent par exemple par un dispositif de verin.Referring to the drawing, it can be seen that an installation according to the present invention is in the form of an
Les pièces à traiter telles que 18 sont suspendues à l'aide de crochets 20, sur un transporteur ou convoyeur 22 qui assure leur défilement devant la tête de pulvérisation 12 qui en effectue leur revêtement.The parts to be treated such as 18 are suspended using
Ainsi qu'on l'a expliqué dans la description qui précède, l'invention se propose de traiter toutes les faces des pièces à traiter 18 à l'aide d'une tête de pulvérisation unique 12. A cet effet, le parcours suivi par les pièces, c'est à dire la configuration du transporteur ou convoyeur 20 présente une forme originale.As explained in the preceding description, the invention proposes to treat all the faces of the parts to be treated 18 using a
Comme on le voit dans cet exemple de réalisation non limitatif représenté en détail sur la figure 2, le parcours des pièces à traiter présente les parties suivantes :
- Une première partie 24 sensiblement rectiligne, située à l'intérieur de l'enceinte de pulvérisation 10 et qui amène successivement l'une des faces des pièces à traiter en regard de la tête de pulvérisation 12 sur l'un des côtés de cette dernière ;
- Une première courbe à 90° 26 suivie d'une seconde courbe également à 90° 28 et dans le même sens que la courbe 26, de manière à ramener les pièces à traiter sur une partie de trajectoire 30, rectiligne, parallèle à la partie de trajectoire 24 mais située à l'extérieur de l'enceinte de traitement 10 ;
- Une troisième courbe à 90° 32 suivie d'une quatrième courbe 34 également à 90° et dans le même sens que la courbe 32, afin de ramener les pièces à traiter sur une partie de trajectoire 36 sensiblement rectiligne et symétrique à la partie de trajectoire 24 et située comme cette dernière à l'intérieur de l'enceinte de pulvérisation 10. Sur cette partie de trajectoire 36, les pièces à traiter passent devant la tête de pulvérisation 12 qui projette la matière de revêtement sur la face des pièces qui n'a pas été traitée lors du passage de la pièce le long de la partie de trajectoire 24.As can be seen in this nonlimiting exemplary embodiment shown in detail in FIG. 2, the path of the parts to be treated has the following parts:
- A
- A first curve at 90 ° 26 followed by a second curve also at 90 ° 28 and in the same direction as
- A third curve at 90 ° 32 followed by a
Bien entendu et sans sortir du cadre de la présente invention, la partie de trajectoire dénommée détour qui est constituée par les courbes 26, 28, 32, 34 ainsi que par la partie 30 qui font subir au pièces une rotation de 360° peut présenter toute forme et longueur quelconque.Of course and without departing from the scope of the present invention, the part of the trajectory called a detour which is constituted by the
Comme on le voit sur le dessin, le système de convoyage comporte une partie de trajectoire d'alimentation 38 située à l'extérieur de l'enceinte de pulvérisation 10, qui peut être de forme quelconque, et qui se prolonge selon la première partie rectiligne 24. De même, le système de convoyage comporte une partie de trajectoire d'évacuation 40 qui peut être également de forme quelconque et qui prolonge la partie rectiligne de trajectoire 36 située dans l'enceinte de traitement 10.As can be seen in the drawing, the conveyor system comprises a part of the
Grâce aux perfecftionnements décrits ci-dessus, on peut traiter des pièces présentant toutes formes et dimensions, à l'aide d'une tête unique de pulvérisation 12, la forme de la trajectoire du système de convoyage auquel sont suspendues les pièces 18, permettant d'amener successivement chacune des faces de ladite pièce devant la tête de pulvérisation 12.Thanks to the improvements described above, it is possible to treat parts having all shapes and dimensions, using a
En outre, dans le système perfectionné selon la présente invention, il n'est pas nécessaire d'utiliser des crochets spéciaux pour la suspension des pièces et celles-ci peuvent être accrochées sur les chariots mobiles des systèmes de convoyage, par l'intérmédiaire d'un ou de plusieurs points d'accrochage en fonction des dimensions des pièces, ce qui permet d'effectuer des revêtements sur les deux faces d'une même pièce à l'aide d'un moyen de pulvérisation unique, sans retournement de la pièce sur son système d'accrochage et de suspension. Par ailleurs, le dispositif selon l'invention permet d'économiser de l'espace par rapport aux solutions antérieures rappelées ci-dessus étant donné que la trajectoire du système de convoyage des pièces à l'intérieur et à l'extérieur de l'enceinte de pulvérisation pour assurer le traitement de toutes les faces de ces pièces est particulièrement compact ainsi que le montre clairement la figure 2.In addition, in the improved system according to the present invention, it is not necessary to use special hooks for hanging the parts and these can be hung on the mobile carriages of the conveyor systems, by means of '' one or more attachment points depending on the dimensions of the parts, which allows coatings to be made on both sides of the same part using a single spraying means, without turning the part over on its attachment and suspension system. Furthermore, the device according to the invention saves space compared to the previous solutions mentioned above since the trajectory of the system for conveying the pieces inside and outside the enclosure spray to ensure the treatment of all the faces of these parts is particularly compact as clearly shown in Figure 2.
On remarquera en outre que le système objet de l'invention peut être appliqué à toute installation de pulvérisation comportant un moyen unique de pulvérisation par exemple une seule tête, étant donné qu'il suffit simplement de modifier le système transporteur qui assure le déplacement des pièces à l'intérieur de l'enceinte de traitement.It will also be noted that the system which is the subject of the invention can be applied to any spraying installation comprising a single spraying means, for example a single head, since it is sufficient to modify the conveyor system which ensures the movement of the parts inside the treatment enclosure.
Il demeure bien entendu que la présente invention n'est pas limitée aux divers exemples de réalisation décrits ci-dessus mais qu'elle en englobe toutes les variantes. C'est ainsi par exemple que les deux partie 24 36 de la trajectoire du système de convoyage à l'intérieur de la zone de revêtement par pulvérisation peuvent présenter des formes et longueurs différentes en regard de la tête de pulvérisation sans définition géométrique particulière. De même la tête ou le moyen de pulvérisation peut être fixe sans subir de mouvement de balayage et la face de pulvérisation du disque ou du bol, lorsqu'on utilise une tête de pulvérisation électrostatique, peut être situé soit dans un plan horizontal soit dans un plan incliné par rapport à l'horizontale. Enfin, dans la description qui précède on a donné comme exemple d'application une tête de pulvérisation électrostatique. Il ne s'agit là que d'un exemple, on peut en effet utiliser d'autres moyens pour la projection et la pulvérisation du produit de revêtement par exemple un pistolet à pulvérisation par air comprimé ou par haute pression avec ou sans projection additionnelle par champ électrostatique.It remains to be understood that the present invention is not limited to the various exemplary embodiments described above but that it encompasses all the variants thereof. For example, the two
