Description

L'invention concerne les articles comprenant deux pièces collées l'une à l'autre, notamment les articles destinés à faire partie d'un véhicule automobile. The invention relates to articles comprising two pieces bonded to each other, including articles intended to be part of a motor vehicle.
Pour coller des pièces l'une à l'autre, en particulier des pièces en matière plastique, on utilise en général une ou plusieurs machines qui dosent, mélangent et déposent la colle. Ces machines peuvent comprendre des mélangeurs dynamiques qui ont pour inconvénient de devoir être nettoyés régulièrement. Elles peuvent alternativement comprendre des mélangeurs statiques qui eux doivent être remplacés à intervalles réguliers. Dans tous les cas, la consommation totale de colle et de solvant s'avère élevée. A chaque fois, il est préférable dans l'intérêt des machines que la période nécessaire pour le durcissement de la colle soit la plus longue possible, tandis que cette période doit être la plus courte possible pour maintenir une cadence de production élevée et abaisser le prix de revient. Ces inconvénients sont générés par l'emploi d'une colle à deux composants qui doivent être mélangés en vue du durcissement de la colle. L'invention vise plus généralement les articles réalisés au moyen d'une colle à un ou deux composants. In order to glue pieces together, in particular plastic parts, one or more machines are generally used which dose, mix and deposit the glue. These machines may include dynamic mixers which have the disadvantage of having to be cleaned regularly. They can alternatively include static mixers which must be replaced at regular intervals. In all cases, the total consumption of glue and solvent is high. Each time, it is preferable in the interest of the machines that the period necessary for the hardening of the glue is the longest possible, while this period must be as short as possible to maintain a high rate of production and lower the price of return. These disadvantages are generated by the use of a two-component glue which must be mixed in order to harden the glue. The invention more generally relates to articles made by means of a glue with one or two components.
Un but de l'invention est de faciliter l'encollage de deux pièces devant être fixées l'une à l'autre. An object of the invention is to facilitate the gluing of two parts to be fixed to one another.
A cet effet, on prévoit selon l'invention un procédé de collage de deux pièces comprenant les étapes consistant à : - introduire au moins un composant de colle entre les deux pièces à l'état assemblé ; et - mettre les pièces en mouvement relatif pour répartir le ou chaque composant entre les pièces. For this purpose, there is provided according to the invention a method of bonding two parts comprising the steps of: - introducing at least one adhesive component between the two parts in the assembled state; and - put the parts in relative motion to distribute the or each component between the parts.
Ainsi, lorsque la colle comprend un unique composant, sachant que la répartition de la colle est uniformisée par la mise en mouvement des pièces, l'introduction de la colle entre les deux pièces peut se faire de façon plus sommaire ou plus grossière, de façon à accroître la cadence de production. Lorsque la colle comprend deux composants, le procédé selon l'invention autorise l'introduction de ces deux composants séparément (par exemple à travers un orifice ou à travers deux orifices respectifs). La mise en mouvement des pièces non seulement répartit chaque composant entre les deux pièces mais en outre entraîne le mélange des deux composants l'un avec l'autre. Il n'est donc plus nécessaire de mélanger Thus, when the glue comprises a single component, knowing that the distribution of the glue is uniformized by the moving parts, the introduction of the glue between the two parts can be more basic or coarser, so to increase the rate of production. When the glue comprises two components, the method according to the invention allows the introduction of these two components separately (for example through an orifice or through two respective orifices). The movement of the parts not only distributes each component between the two parts but also causes the two components to mix with each other. It is no longer necessary to mix
<Desc/Clms Page number 2><Desc / Clms Page number 2>
étroitement les deux composants avant de les introduire entre les deux pièces. close the two components before inserting them between the two parts.
L'entretien de la machine d'introduction est donc simplifié et sa durée de vie prolongée. L'invention permettant un mélange des composants de la colle in situ, une polymérisation rapide peut commencer dès le début du mélange. L'invention conduit donc à un gain de productivité en permettant l'utilisation de colles à deux composants à prise très rapide. Maintenance of the introducer machine is thus simplified and its service life extended. The invention allows a mixture of glue components in situ, a rapid polymerization can begin from the beginning of the mixture. The invention therefore leads to a productivity gain by allowing the use of two-component glues very fast setting.
Avantageusement on met les pièces en mouvement en gardant les pièces à l'état assemblé. Advantageously, the parts are moved while keeping the parts in the assembled state.
Ainsi, aucune fuite ou débordement de colle n'est à craindre. Thus, no leakage or overflow of glue is to be feared.
Avantageusement la colle comprend deux composants, l'introduction étant menée en introduisant les composants séparément entre les pièces. Advantageously, the glue comprises two components, the introduction being conducted by introducing the components separately between the parts.
Avantageusement au moins l'une des deux pièces présente un orifice à travers lequel on introduit le composant ou l'un des composants. Advantageously, at least one of the two parts has an orifice through which the component or one of the components is introduced.

Avantageusement on introduit les deux composants à travers les deux orifices respectifs. Advantageously, the two components are introduced through the two respective orifices.
De préférence, au moins l'une des deux pièces présente des reliefs et/ou des cavités aptes à favoriser la répartition durant l'étape de mise en mouvement. Preferably, at least one of the two parts has reliefs and / or cavities able to promote distribution during the setting step.
Lors de l'utilisation d'une colle à deux composants, les cavités et reliefs favorisent également l'obtention d'un mélange de bonne qualité des deux composants entre les pièces. When using a two-component glue, the cavities and reliefs also help to obtain a good quality mixture of the two components between the pieces.
Avantageusement les reliefs et/ou les cavités sont discontinus suivant la direction du mouvement relatif. Advantageously, the reliefs and / or the cavities are discontinuous in the direction of the relative movement.
Avantageusement, les pièces sont aptes à constituer un assemblage mâlefemelle. Advantageously, the parts are able to constitute a male male assembly.
Avantageusement, la pièce femelle présente le ou les orifices.

On prévoit encore selon l'invention une installation d'encollage d'un article comprenant des moyens pour amener au moins un composant de colle entre deux pièces de l'article à l'état assemblé et des moyens pour mettre les deux pièces en mouvement relatif. According to the invention there is also provided a sizing installation for an article comprising means for bringing at least one glue component between two parts of the article in the assembled state and means for setting the two parts in relative motion. .
Avantageusement les moyens de mise en mouvement sont aptes à mettre les pièces en mouvement en les gardant à l'état assemblé. Advantageously, the moving means are able to put the parts in motion while keeping them in the assembled state.
Avantageusement les moyens d'amenée sont aptes à amener deux composants de colle séparément entre les deux pièces. Advantageously, the feed means are capable of bringing two glue components separately between the two parts.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode préféré de réalisation donné à titre d'exemple non limitatif. Aux dessins annexés : - la figure 1 est une vue schématique d'une installation pour la mise en oeuvre du procédé de l'invention, - la figure 2 est une vue en élévation d'un article fabriqué au moyen du procédé de l'invention, - la figure 3 est une vue d'une extrémité d'une pièce de l'article de la figure 2, et - les figures 4,5 et 6 sont des vues de détail de variantes de réalisation de l'article de la figure 3. Other features and advantages of the invention will become apparent in the following description of a preferred embodiment given by way of non-limiting example. In the accompanying drawings: - Figure 1 is a schematic view of an installation for carrying out the method of the invention; - Figure 2 is an elevational view of an article manufactured using the method of the invention; FIG. 3 is a view of one end of a part of the article of FIG. 2, and FIGS. 5 and 6 are detailed views of alternative embodiments of the article of FIG. 3.
La figure 1 présente un mode préféré de réalisation de l'installation pour la mise en oeuvre du procédé de l'invention. Cette installation 2 comprend deux réservoirs 4,6 destinés à recevoir deux composants 8,10 respectifs d'une même colle connue en soi. Cette colle est telle qu'aucun des deux composants 8,10 ne durcit pourvu qu'ils soient conservés séparément l'un de l'autre. Lorsque ces deux composants sont mélangés, ils entraînent à l'issue d'un délai prédéterminé le durcissement de la colle. La colle pourra être une colle polyuréthanne, une colle époxy ou une colle acrylique par exemple. FIG. 1 shows a preferred embodiment of the installation for implementing the method of the invention. This installation 2 comprises two reservoirs 4,6 intended to receive two respective components 8, 10 of the same adhesive known per se. This glue is such that none of the two components 8, 10 cures as long as they are kept separately from each other. When these two components are mixed, they cause after a predetermined time the hardening of the glue. The glue may be a polyurethane glue, an epoxy glue or an acrylic glue, for example.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
L'installation contient deux organes 12 pour le pompage et le dosage de chacun des composants 8 et 10, reliés par des conduits adaptés aux deux réservoirs respectifs. The installation contains two members 12 for pumping and dosing each of the components 8 and 10, connected by conduits adapted to the two respective tanks.
L'installation comprend également deux têtes d'injection 14 reliées de façon adaptée aux organes 12 respectifs en vue d'injecter les composants respectifs dans deux orifices d'une pièce. The installation also comprises two injection heads 14 suitably connected to the respective members 12 for injecting the respective components into two orifices in one piece.
L'installation comprend en outre un actionneur 16 apte à mettre en mouvement une pièce reçue dans l'installation. En l'espèce, cette mise en mouvement étant une mise en rotation, l'actionneur 16 pourra comprendre un moteur rotatif. The installation further comprises an actuator 16 adapted to set in motion a piece received in the installation. In this case, this setting in motion being a rotation, the actuator 16 may comprise a rotary motor.
Dans le présent mode de réalisation, le procédé de l'invention vise à fabriquer une biellette 20 telle que celle illustrée à la figure 2. Cette biellette est destinée à faire partie d'une suspension de véhicule automobile. Elle comprend une tige principale allongée rectiligne 22 à section droite circulaire. Elle comprend également deux embouts 24, 26 fixés aux extrémités respectives de la tige 22. Chacun des embouts est apte à être fixé par ailleurs à un autre élément respectif du véhicule, ces éléments n'ayant pas été représentés. Le collage dont il est ici question sert à fixer l'embout 26 à l'une des extrémités de la tige 22. Pour cela, l'embout 26 comprend un manchon 28 de forme générale cylindrique et présentant des faces externe 30 et interne 32 également cylindriques coaxiales d'axe 34. Une extrémité de la tige 22 est destinée à être reçue coaxialement dans le manchon. In the present embodiment, the method of the invention aims to manufacture a rod 20 such as that illustrated in Figure 2. This rod is intended to be part of a motor vehicle suspension. It comprises a rectilinear elongated main stem 22 with a circular cross section. It also comprises two end pieces 24, 26 attached to the respective ends of the rod 22. Each of the end pieces is adapted to be fixed elsewhere to another respective element of the vehicle, these elements not being shown. The bonding in question here serves to fix the tip 26 at one end of the rod 22. For this, the tip 26 comprises a sleeve 28 of generally cylindrical shape and having outer faces 30 and inner 32 also coaxial cylindrical axis 34. One end of the rod 22 is intended to be received coaxially in the sleeve.
A mi chemin de ses deux extrémités axiales, le manchon présente deux orifices 36 traversant la paroi du manchon et s'étendant radialement par référence à l'axe 34. Ces deux orifices sont coaxiaux l'un à l'autre et s'étendent de part et d'autre de l'axe 34. Halfway between its two axial ends, the sleeve has two orifices 36 passing through the wall of the sleeve and extending radially with reference to the axis 34. These two orifices are coaxial with each other and extend from one to the other. on both sides of axis 34.
L'extrémité précitée de la tige 22 présente des reliefs 38 s'étendant en saillie de sa face cylindrique en direction radiale par référence à l'axe 34. En l'espèce, ces reliefs ont une forme conique. Les reliefs 38 sont disposés en cercles et en quinconce sur la circonférence de la tige. Plusieurs rangées de reliefs se succèdent ainsi le long de la tige. Les reliefs sont discontinus et séparés les uns des autres en particulier suivant la direction circonférentielle. La tige avec ses reliefs est dimensionnée de sorte que, lorsqu'elle est reçue dans le manchon 28, la The aforementioned end of the rod 22 has reliefs 38 projecting from its cylindrical face radially with reference to the axis 34. In this case, these reliefs have a conical shape. The reliefs 38 are arranged in circles and staggered on the circumference of the rod. Several rows of reliefs succeed each other along the stem. The reliefs are discontinuous and separated from each other particularly in the circumferential direction. The stem with its reliefs is dimensioned so that when it is received in the sleeve 28, the
<Desc/Clms Page number 5><Desc / Clms Page number 5>
pointe des reliefs est voisine de la face interne 32 du manchon comme illustré à la figure 1. point of the reliefs is close to the inner face 32 of the sleeve as shown in Figure 1.
La tige et le manchon pourront être en matière composite thermodurcissable ou thermoplastique. Il pourra notamment s'agir de polypropylène ou de polyamide, l'un et l'autre pouvant être renforcé par des fibres de verre de façon connue en soi. The rod and the sleeve may be made of thermosetting or thermoplastic composite material. It may in particular be polypropylene or polyamide, one and the other being able to be reinforced by glass fibers in a manner known per se.
Le procédé selon l'invention est mise en oeuvre de la façon suivante. Tout d'abord, on assemble le manchon 28 éventuellement préalablement fixé à l'embout 26 avec la tige 22 en introduisant celle-ci dans le manchon. Le manchon et la tige réalisent ainsi un assemblage mâle-femelle illustré à la figure 1. The process according to the invention is carried out as follows. First, it assembles the sleeve 28 possibly previously attached to the tip 26 with the rod 22 by introducing it into the sleeve. The sleeve and the rod thus realize a male-female assembly illustrated in FIG.
La tige 22 est montée sur l'actionneur 16 afin de pouvoir être mise en rotation par celui-ci autour de son axe 34. Quant au manchon 28, il est maintenu rigidement par des moyens classiques non représentés. The rod 22 is mounted on the actuator 16 in order to be rotated by it around its axis 34. As for the sleeve 28, it is held rigidly by conventional means not shown.
On commande ensuite l'injection des deux composants de colle 8, 10 au moyen des injecteurs 14 pénétrant à travers les orifices 36 respectifs. L'injection peut être simultanée pour les deux composants. Toutefois, les composants sont introduits séparément à travers les orifices respectifs. Simultanément à l'injection ou peu après celle-ci, on met la tige en mouvement au moyen de l'actionneur 16 tandis que le manchon reste immobile. Grâce aux reliefs 38, ce mouvement répartit chacun des deux composants de colle dans l'espace délimité entre les deux pièces et de surcroît effectue le mélange de ces deux composants l'un avec l'autre pour constituer une couche de colle homogène 39. La mise en rotation relative des deux pièces s'effectue en gardant les pièces à l'état assemblé. The two glue components 8, 10 are then controlled by injectors 14 penetrating through the respective orifices 36. The injection can be simultaneous for both components. However, the components are introduced separately through the respective orifices. Simultaneously with the injection or shortly after it, the rod is moved by means of the actuator 16 while the sleeve remains stationary. Thanks to the reliefs 38, this movement distributes each of the two glue components in the space defined between the two parts and, in addition, mixes these two components together to form a homogeneous glue layer 39. Relative rotation of the two parts is carried out by keeping the parts in the assembled state.
Lorsque les deux composants sont convenablement répartis et mélangés dans l'espace délimité entre les deux pièces, on interrompt le mouvement de rotation. On laisse ensuite durcir le mélange jusqu'à immobilisation rigide de la tige
dans le manchon. Comme on le voit, dans le procédé de l'invention, c'est l'article lui-même qui sert de mélangeur pour les deux composants de la colle. When the two components are properly distributed and mixed in the space defined between the two parts, the rotational movement is interrupted. The mixture is then allowed to harden until the rod is rigidly immobilized.
in the sleeve. As seen, in the method of the invention, it is the article itself that serves as a mixer for the two components of the glue.
On pourra remplacer les reliefs par des cavités, ou encore utiliser conjointement des reliefs et des cavités. La pièce présentant les reliefs et/ou les cavités pourra être réalisée par moulage. Sachant que ni les reliefs ni les cavités We can replace the reliefs with cavities, or even use reliefs and cavities. The piece having the reliefs and / or the cavities may be made by molding. Knowing that neither reliefs nor cavities

n'ont besoin d'avoir une forme ou une qualité de surface très précise, ils pourront être démoulés à force c'est-à-dire sans prévoir de dépouille spécifique. need to have a shape or a very precise surface quality, they can be demolded by force that is to say without providing specific skin.
La mise en rotation relative des deux pièces peut également servir à déclencher la polymérisation en vue du durcissement de la colle. La possibilité d'effectuer le mélange in situ des deux composants de la colle dans l'article entraîne qu'aucun mélangeur n'est nécessaire sur l'installation et que les étapes de nettoyage et de maintenance de celle-ci sont simplifiées. The relative rotation of the two parts can also be used to trigger the polymerization for curing the glue. The possibility of mixing the two components of the adhesive in situ in the article means that no mixer is necessary on the installation and that the steps of cleaning and maintenance thereof are simplified.
On a illustré aux figures 4 à 6 des variantes de réalisation des reliefs. FIGS. 4 to 6 illustrate embodiments of the reliefs.
Ainsi sur la figure 4, le relief 38 a de profil une forme en triangle dont un angle est obtus, le triangle étant accolé à la tige 22 par l'un des côtés définissant cet angle. Ce relief a une allure générale en aileron de requin ou en épine de rose. Thus, in FIG. 4, the relief 38 has in profile a triangular shape whose angle is obtuse, the triangle being attached to the rod 22 by one of the sides defining this angle. This relief has a general look in shark fin or rose spine.
Sur la figure 5, le relief 38 a une forme générale de dôme arrondi à son sommet. In Figure 5, the relief 38 has a generally rounded dome at its apex.
Sur la figure 6, le relief a une forme de pavé. In Figure 6, the relief has a pavement shape.
Le procédé est applicable aux articles présentant une symétrie de révolution. Il est également applicable à d'autres formes d'article, notamment en déplaçant les pièces relativement à coulissement. The method is applicable to articles having a symmetry of revolution. It is also applicable to other forms of article, including moving parts relatively sliding.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications dans le cadre de celle-ci. Of course, many modifications can be made to the invention within the scope of this invention.
De nombreuses autres formes de relief sont envisageables. Many other forms of relief are possible.
Au moins l'un des orifices d'introduction d'un composant de colle pourra
être prévu sur la pièce mâle. At least one of the introduction orifices of a glue component may
be provided on the male part.
On pourra également prévoir d'autres dispositions des reliefs sur la tige. It will also be possible to provide other arrangements of the reliefs on the rod.
L'article fabriqué au moyen du procédé de l'invention pourra notamment faire partie d'un véhicule automobile ou d'un appareil électroménager.The article manufactured by means of the method of the invention may in particular be part of a motor vehicle or a household appliance.
