Description

La présente invention se rapporte à un dispositif de conditionnement d'un joint,The present invention relates to a device for packaging a seal,

En fonctionnement, un joint est intercalé entre deux éléments et permet d'assurer la continuité fluidique entre deux conduits chacun ménagé dans un des éléments. A cet effet, le joint comprend une ouverture correspondant aux conduits et une surface d'étanchéité susceptible d'être intercalée entre les éléments à étancher afin d'assurer l'étanchéité entre les deux éléments et entre les conduits et l'extérieur. Selon les variantes, le joint peut comprendre au niveau de la surface d'étanchéité des trous de passage pour des éléments de serrage prévus pour maintenir les deux éléments à étancher l'un contre l'autre.In operation, a seal is interposed between two elements and ensures fluidic continuity between two ducts each formed in one of the elements. For this purpose, the seal comprises an opening corresponding to the ducts and a sealing surface capable of being interposed between the elements to be sealed in order to ensure the seal between the two elements and between the ducts and the outside. According to the variants, the seal may comprise at the sealing surface passage holes for clamping elements provided to maintain the two elements to be sealed against each other.

L'invention se rapporte plus particulièrement aux joints métalliques tels que les joints métalliques assurant l'étanchéité entre les différents éléments constituants la ligne d'échappement qui s'étend depuis le bloc moteur jusqu'à la sortie des gaz d'échappement.The invention relates more particularly to metal seals such as metal seals sealing between the various elements constituting the exhaust line extending from the engine block to the outlet of the exhaust gas.

Ce type de joint comprend généralement une ou plusieurs feuilles métalliques avec ou non des formes adaptées permettant de renforcer l'étanchéité. Pour améliorer l'étanchéité, ce type de joint peut comprendre un revêtement, par exemple en élastomère, au niveau d'au moins une face formant la surface d'étanchéité. Pour conserver son efficacité, ce revêtement élastomère ne doit pas être endommagé jusqu'à ce que le joint soit intercalé entre les deux pièces à étancher.This type of seal generally comprises one or more metal sheets with or without suitable shapes to strengthen the seal. To improve the seal, this type of seal may comprise a coating, for example elastomer, at at least one face forming the sealing surface. To maintain its effectiveness, this elastomeric coating must not be damaged until the seal is inserted between the two parts to be sealed.

Généralement, ce type de joint est fabriqué et placé dans un conditionnement dit initial au niveau d'un premier site, puis est acheminé vers un autre site, par exemple un site de fabrication de collecteur, au niveau duquel le joint est sorti de son conditionnement initial pour être monté sur un sous ensemble, par exemple un collecteur, l'ensemble étant ensuite acheminé vers un troisième site au niveau duquel le sous ensemble est intégré dans un ensemble plus important, par exemple au niveau duquel le collecteur est fixé sur le moteur.Generally, this type of seal is manufactured and placed in a so-called initial packaging at a first site, then is conveyed to another site, for example a collector manufacturing site, at which the seal is released. from its initial conditioning to be mounted on a subassembly, for example a collector, the assembly then being conveyed to a third site at which the subset is integrated in a larger assembly, for example at which the collector is fixed on the engine.

Le conditionnement initial est généralement une feuille de carton sur lequel le joint est maintenu à l'aide d'un film plastique. Ce type de conditionnement permet de protéger correctement l'une des faces, celle orientée vers le carton. Toutefois, celle recouverte par le film plastique n'est pas correctement protégée, notamment si elle comprend un revêtement fragile en élastomère.The initial packaging is generally a sheet of cardboard on which the seal is held with a plastic film. This type of packaging makes it possible to correctly protect one of the faces, the one facing the carton. However, that covered by the plastic film is not properly protected, especially if it comprises a fragile elastomer coating.

Ensuite, au niveau du deuxième site, le joint est sorti de son conditionnement initial pour être placé sur un collecteur par exemple. Lors de cette manipulation le joint n'est pas protégé et peut être endommagé. Par ailleurs, ce type de conditionnement conduit à produire des déchets (carton, film plastique) au niveau du deuxième site qu'il convient de traiter.Then, at the second site, the seal is removed from its initial packaging to be placed on a collector for example. During this operation the seal is not protected and can be damaged. Furthermore, this type of packaging leads to produce waste (cardboard, plastic film) at the second site that should be treated.

Le joint placé sur le collecteur doit conserver sa position jusqu'à la mise en place du collecteur sur le moteur. Par ailleurs, on doit veiller à ce qu'aucun corps étranger ne pénètre à l'intérieur du collecteur, A cet effet, le collecteur et le joint sont enveloppés d'un film plastique. Ce mode de conditionnement n'est pas satisfaisant car d'une part le film plastique ne permet pas de protéger correctement le joint, et d'autre part, il n'assure pas un maintien en position efficace du joint sur le collecteur.The seal placed on the manifold must maintain its position until the collector is placed on the engine. Furthermore, it must be ensured that no foreign body enters the manifold. For this purpose, the collector and the seal are wrapped in a plastic film. This mode of packaging is unsatisfactory because on the one hand the plastic film does not properly protect the seal, and secondly, it does not ensure maintenance in effective position of the seal on the manifold.

Aussi, la présente invention vise à pallier les inconvénients mentionnés ci-dessus en proposant un dispositif de conditionnement d'un joint, de conception simple, procurant une protection satisfaisante du joint jusqu'à sa mise en place finale, et facilitant sa manipulation et sa mise en place.Also, the present invention aims to overcome the drawbacks mentioned above by proposing a device for packaging a seal, of simple design, providing satisfactory protection of the seal until its final installation, and facilitating its handling and its set up.

A cet effet, l'invention a pour objet un dispositif de conditionnement d'un joint caractérisé en ce qu'il comprend une surface de protection, adaptée à la forme du joint, avec sur l'une de ses faces au moins un élément en saillie au niveau duquel est susceptible de s'immobiliser par coincement ou par clipsage une partie du joint.For this purpose, the subject of the invention is a device for conditioning a seal, characterized in that it comprises a protective surface, adapted to the shape of the seal, with on one of its faces at least one element protrusion at the level which is likely to immobilize by wedging or clipping a portion of the seal.

Sur la figure 3, on a représenté en 10 un exemple de joint. Ce dernier comprend une surface d'étanchéité sensiblement plane au niveau de laquelle est ménagée au moins une ouverture 12 susceptible de coopérer avec les conduits ou les cavités des éléments à étancher. Selon l'exemple illustré, le joint 10 comprend au niveau de la surface d'étanchéité des trous 14 pour permettre le passage d'éléments de serrage.In Figure 3, there is shown at 10 an example of a seal. The latter comprises a substantially flat sealing surface at which is provided at least one opening 12 capable of cooperating with the conduits or cavities of the elements to be sealed. According to the illustrated example, the seal 10 comprises at the sealing surface of the holes 14 to allow the passage of clamping elements.

Selon l'exemple illustré, l'ouverture 12 est sensiblement circulaire et le pourtour de la surface d'étanchéité est sensiblement circulaire et concentrique à l'ouverture avec des oreilles 16 au droit des trous de passage 14. Le joint comprend une ou plusieurs feuilles, métalliques ou non, dont au moins une face peut être revêtue d'un revêtement, notamment en élastomère pour améliorer l'étanchéité.According to the illustrated example, the opening 12 is substantially circular and the periphery of the sealing surface is substantially circular and concentric to the opening with ears 16 to the right of the passage holes 14. The seal comprises one or more sheets , metal or not, at least one side may be coated with a coating, in particular elastomer to improve the seal.

Ce type de joint 10 peut être intercalé entre un bloc moteur et un collecteur.This type of seal 10 may be interposed between a motor unit and a collector.

Toutefois, pour d'autres variantes, le joint 10 peut ne comporter aucun trou de passage à savoir le joint peut se présenter sous la forme d'un anneau ou d'une rondelle. Dans d'autres cas, il peut comprendre d'autres orifices pour d'autres fonctions, par exemple des orifices pour les fluides de refroidissement dans le cas d'un joint de culasse. De même, le pourtour du joint peut être plus ou moins complexe. Pour assurer son maintien au niveau d'un sous ensemble, tel que par exemple un collecteur, le joint 10 comprend au niveau d'au moins un trou de passage 14 des moyens 18 de maintien sous forme d'ergots permettant de réduire légèrement le diamètre du trou de passage.However, for other variants, the seal 10 may have no through holes, ie the seal may be in the form of a ring or a washer. In other cases, it may comprise other orifices for other functions, for example orifices for cooling fluids in the case of a head gasket. Similarly, the periphery of the joint can be more or less complex. To ensure its maintenance at a subassembly, such as for example a manifold, the seal 10 comprises at least one through hole 14 holding means 18 in the form of pins to reduce slightly the diameter of the passage hole.

Sur les figures 1A à 1D, 2A, 2B, 4A, 4B, on a représenté en 20 un dispositif de conditionnement d'un joint 10 selon l'invention. Ce dispositif comprend une surface 22 de protection, adaptée à la forme du joint 10, avec sur l'une de ses faces au moins un élément en saillie 24 au niveau duquel est susceptible de s'immobiliser par coincement ou par clipsage le joint au niveau de l'ouverture 12 ou au moins une des ouvertures 12 du joint 10. En variante, l'élément en saillie 24 pourrait immobiliser par coincement ou par clipsage toute autre partie du joint, par exemple son bord extérieur.In FIGS. 1A to 1D, 2A, 2B, 4A, 4B, there is shown at 20 a device for packaging a seal 10 according to the invention. This device comprises a protective surface 22, adapted to the shape of the seal 10, with on one of its faces at least one projecting element 24 at the level of which is likely to immobilize by wedging or clipping the seal at the opening 12 or at least one of the openings 12 of the seal 10. Alternatively, the projecting element 24 could immobilize by wedging or clipping any other part of the seal, for example its outer edge.

Le fait de prévoir le maintien du joint par coincement ou par clipsage permet de ne pas détruire le dispositif de conditionnement pour libérer le joint et de pouvoir le réutiliser contrairement aux dispositifs existants.The fact of providing the maintenance of the seal by wedging or clipping allows not to destroy the packaging device to release the seal and to reuse it unlike existing devices.

Selon un mode de réalisation, la surface de protection 22 est sensiblement plane et ledit au moins un élément 24 en saillie se présente sous la forme d'une nervure ménagée au niveau de la surface de protection, ladite nervure ayant une section en forme de U. De préférence, la nervure 24, sensiblement circulaire, a un diamètre extérieur légèrement inférieur à celui de l'ouverture 12 du joint et comprend au moins une excroissance 26 en périphérie pour permettre de maintenir le joint par coincement au niveau de l'ouverture 12. Cette solution permet de limiter les zones de contact entre le joint et la nervure 24.According to one embodiment, the protective surface 22 is substantially flat and said at least one projecting element 24 is in the form of a rib formed at the level of the protective surface, said rib having a U-shaped section. Preferably, the rib 24, substantially circular, has an outside diameter slightly smaller than that of the opening 12 of the seal and comprises at least one protrusion 26 at the periphery to allow the seal to be held by jamming at the opening 12 This solution makes it possible to limit the areas of contact between the seal and the rib 24.

De préférence, la nervure 24 comprend au moins deux excroissances 26 diamétralement opposées, la distance D entre les extrémités des excroissances 26 étant légèrement supérieure au diamètre de l'ouverture 12 du joint 10. Pour un meilleur maintien, la nervure 24 comprend quatre excroissances 26, comme illustré sur la figure 2B.Preferably, the rib 24 comprises at least two excrescences 26 diametrically opposed, the distance D between the ends of the protuberances 26 being slightly greater than the diameter of the opening 12 of the seal 10. For a better maintenance, the rib 24 comprises four protuberances 26 as shown in Figure 2B.

Selon les variantes, la surface de protection 22 peut recouvrir la totalité de la surface du joint ou uniquement une partie du joint correspondant aux zones sensibles du joint à protéger.According to the variants, the protective surface 22 may cover the entire surface of the seal or only a portion of the seal corresponding to the sensitive areas of the seal to be protected.

Pour faciliter la manipulation du joint, le dispositif de protection 10 comprend des moyens 28 de préhension. Selon un mode de réalisation, les moyens 28 de préhension se présentent sous la forme d'un bossage ménagé au niveau d'une des faces de la surface 22 de protection, celle opposée à l'élément 24 en saittie.To facilitate handling of the seal, the protective device 10 comprises gripping means 28. According to one embodiment, the gripping means 28 are in the form of a boss formed at one of the faces of the protective surface 22, the opposite of the element 24 in known.

De préférence, le bossage 28 est creux et a une forme oblongue, les excroissances 26 prévues au niveau de la nervure étant prévues au droit des portions sensiblement rectilignes de la forme oblongue, de part et d'autre de la forme oblongue.Preferably, the boss 28 is hollow and has an oblong shape, the protuberances 26 provided at the rib being provided in line with substantially straight portions of the oblong shape, on either side of the oblong shape.

Les formes du bossage creux 28 et de l'élément en saillie 24 sont adaptées pour permettre à l'utilisateur en pressant le bossage creux de déformer légèrement l'élément 24 en saillie pour libérer le joint 10, comme illustré sur les figures 1D et 7.The shapes of the hollow boss 28 and the projecting element 24 are adapted to allow the user by pressing the hollow boss to slightly deform the element 24 protruding to release the seal 10, as shown in Figures 1D and 7 .

De préférence, le dispositif de conditionnement est en matière plastique et obtenu par thermoformage. Toutefois, d'autres matériaux et d'autres modes de réalisation pourraient être envisagés.Preferably, the packaging device is made of plastic material and obtained by thermoforming. However, other materials and other embodiments could be considered.

Selon une autre caractéristique de l'invention, le dispositif de conditionnement 20 comprend des moyens permettant de le solidariser de manière temporaire à un sous ensemble 30. par exemple un collecteur.According to another characteristic of the invention, the packaging device 20 comprises means for temporarily securing it to a subset 30, for example a collector.

Selon une première variante, l'élément 24 en saillie peut être utilisé pour assurer le maintien du dispositif de conditionnement par coincement ou par clipsage de l'élément en saillie à l'extrémité du conduit du sous ensemble 30 susceptible de coopérer avec l'ouverture 12 du joint.According to a first variant, the projecting element 24 may be used to maintain the packaging device by jamming or clipping the protruding element at the end of the duct of the subassembly 30 capable of cooperating with the opening 12 of the seal.

Selon une autre variante, des pattes 32 peuvent être prévues en périphérie de la surface de protection 22, de manière à recouvrir la surface périphérique 34 de la partie terminale du sous ensemble 30, l'écartement entre les pattes 32 diamétralement opposées étant inférieur à la dimension du sous ensemble 30. Selon un mode de réalisation, les pattes 32 s'étendent de manière sensiblement perpendiculaire à la surface de protection 22, dans la même direction que la nervure 24. Les pattes 32 sont déformables pour pincer de manière suffisante le sous ensemble 30 en position de repos et maintenir le dispositif de conditionnement sur le sous ensemble. Les pattes 32 déformables autorisent toutefois le retrait du dispositif de conditionnement du sous ensemble 30, comme illustré sur la figure 7.According to another variant, lugs 32 may be provided at the periphery of the protective surface 22, so as to cover the peripheral surface 34 of the terminal portion of the subassembly 30, the spacing between the diametrically opposite lugs 32 being less than the subassembly size 30. According to one embodiment, the tabs 32 extend substantially perpendicular to the protective surface 22, in the same direction as the rib 24. The tabs 32 are deformable to pinch sufficiently the sub together 30 in the rest position and maintain the packaging device on the subassembly. The deformable legs 32 allow however, the removal of the conditioning device from the subassembly 30, as illustrated in FIG. 7.

Selon une autre variante, un bord périphérique s'étend tout le long du pourtour de la surface de protection 22 de manière sensiblement perpendiculaire à ladite surface de manière à délimiter une cavité en forme de cloche à l'intérieur de laquelle est disposé le joint 10. De préférence, le bord périphérique comprend des découpes de manière à former des pattes 32 entre les découpes,According to another variant, a peripheral edge extends all along the perimeter of the protective surface 22 substantially perpendicularly to said surface so as to define a bell-shaped cavity inside which the gasket 10 is disposed. Preferably, the peripheral edge comprises cutouts so as to form tabs 32 between the cuts,

En complément, la surface 22 de protection dégage les trous 14 de passage. Ces dégagements 36 se prolongent au niveau du bord périphérique de manière à délimiter des pattes 32. Ainsi, l'ensemble constitué par le dispositif de conditionnement et le joint peut être rapporté au niveau de la surface à étancher d'un sous ensemble 30, par exemple un collecteur, comprenant déjà des éléments de fixation 38.In addition, the protective surface 22 disengages the through holes 14. These clearances 36 extend at the peripheral edge so as to delimit tabs 32. Thus, the assembly constituted by the packaging device and the seal can be attached to the level of the surface to be sealed of a subassembly 30, by for example a collector, already comprising fastening elements 38.

Selon une autre caractéristique de l'invention, la surface 22 de protection peut jouer la fonction d'obturateur d'orifices du sous ensemble 30 sur lequel le dispositif est rapporté. A cet effet, la surface de protection 22 a des dimensions et des formes adaptées pour former un obturateur pour au moins une ouverture ménagée au niveau du sous ensemble 30 lorsque le dispositif est placé sur ledit sous ensemble. Cet agencement permet d'éviter l'intrusion d'éléments étrangers dans le conduit du sous ensemble susceptible de coopérer avec l'ouverture du joint.According to another characteristic of the invention, the protective surface 22 may play the shutter function of the orifices of the subassembly 30 on which the device is attached. For this purpose, the protective surface 22 has dimensions and shapes adapted to form a shutter for at least one opening formed at the subassembly 30 when the device is placed on said subassembly. This arrangement makes it possible to prevent the intrusion of foreign elements into the duct of the subassembly capable of cooperating with the opening of the gasket.

Avantageusement, les moyens 18 de maintien susceptibles d'être prévus au niveau d'au moins un trou de passage permettent de renforcer le maintien du joint 10 sur le sous ensemble 30 et également du dispositif de conditionnement.Advantageously, the holding means 18 capable of being provided at at least one through hole make it possible to reinforce the maintenance of the seal 10 on the subassembly 30 and also of the packaging device.

Selon une autre caractéristique de l'invention, les pattes 32 ont une hauteur supérieure à celle de l'élément en saillie 24 de manière à permettre l'empilement des dispositifs de conditionnement avec chacun un joint, comme illustré sur la figure 5. Avantageusement, l'extrémité 40 libre du bord périphérique ou des pattes 32 du dispositif de conditionnement est courbée ou évasée pour favoriser l'empilent et assurer le maintien des dispositifs de conditionnement empilés.According to another characteristic of the invention, the tabs 32 have a height greater than that of the projecting element 24 so as to allow the stacking of the packaging devices with each a seal, as shown in FIG. 5. Advantageously, the free end 40 of the peripheral edge or tabs 32 of the packaging device is curved or flared to promote stacking and maintain the stacked conditioning devices.

L'utilisation du dispositif de conditionnement selon l'invention est relativement simple.The use of the packaging device according to the invention is relatively simple.

Après sa fabrication, un joint 10 est placé dans un dispositif de conditionnement 20, le joint 10 étant maintenu par coincement au niveau de l'élément en saillie 22. Le joint est parfaitement protégé par le dispositif de conditionnement.After its manufacture, a seal 10 is placed in a packaging device 20, the seal 10 being held by wedging at the level of the projecting element 22. The seal is perfectly protected by the packaging device.

Au niveau du site de production des joints 10 ou pendant le transport, les dispositifs de conditionnement avec chacun un joint sont empilés les uns sur les autres comme illustré sur la figure 5. Le bord libre 40 recourbé des pattes 32 favorise l'empilement. Par auleurs, lorsque les dispositifs sont empilés, chaque joint est protégé grâce au dispositif de conditionnement auquel il est relié et au dispositif de conditionnement placé juste dessous.At the site of production of the seals 10 or during transport, the packaging devices each with a seal are stacked on each other as shown in Figure 5. The free edge 40 curved lugs 32 promotes stacking. In addition, when the devices are stacked, each seal is protected by the conditioning device to which it is connected and the conditioning device placed just below.

Au niveau du site de pré-montage du joint sur un sous ensemble, l'opéruteur n'a pas besoin de sortir le joint 10 du dispositif de conditionnement. Il lui suffit de placer l'ensemble, constitué par le joint et son dispositif de conditionnement, à l'extrémité du sous ensemble comme illustré sur la figure 6. Lors de cette opération le joint seul n'est pas manipulé par l'opérateur. Il est toujours protégé par le dispositif de conditionnement. Les pattes 32 permettent de maintenir le joint et son dispositif de conditionnement sur le sous ensemble.At the site of pre-assembly of the seal on a subassembly, the operator does not need to remove the seal 10 of the packaging device. It suffices to place the assembly consisting of the seal and its packaging device at the end of the subassembly as shown in Figure 6. During this operation the joint alone is not handled by the operator. It is always protected by the packaging device. The tabs 32 maintain the seal and its packaging device on the subassembly.

On note que le dispositif de conditionnement facilite la mise en place du joint sur le sous ensemble car les formes des pattes 32 évasées ou recourbées favorisent le centrage du joint.Note that the packaging device facilitates the establishment of the seal on the subassembly because the shapes of the tabs 32 flared or bent favor the centering of the seal.

Par ailleurs, le dispositif de conditionnement permet d'obturer le conduit du sous ensemble 30 et empêche l'intrusion de corps étrangers.Furthermore, the conditioning device makes it possible to seal the duct of the subassembly 30 and prevents the intrusion of foreign bodies.

Enfin, ou niveau du site du montage final, l'opérateur retire aisément le dispositif de conditionnement à l'aide du bossage creux 28 comme illustré sur la figure 7. Ce retrait est favorisé grâce aux moyens 18 de maintien qui permettent de garder le joint 10 sur le sous ensemble 30.Finally, or at the level of the final assembly site, the operator easily removes the conditioning device using the hollow boss 28 as illustrated in FIG. This shrinkage is favored thanks to the holding means 18 which keep the seal 10 on the subassembly 30.

Grâce au dispositif de l'invention, le joint est protégé depuis sa fabrication jusqu'à sa mise en place entre les éléments à étancher. Il n'est jamais manipulé seul.Thanks to the device of the invention, the seal is protected from its manufacture until its establishment between the elements to be sealed. He is never manipulated alone.

De plus, le dispositif de conditionnement selon l'invention est réutilisable ce qui tend à réduire les déchets.In addition, the packaging device according to the invention is reusable which tends to reduce waste.

Bien entendu, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les formes, la nature et les dimensions du joint, qui peut par exemple être un joint de culasse. De même, le dispositif de conditionnement de l'invention peut avoir différentes formes, dimensions, peut être obtenus par différentes techniques et peut être réalisé à partir de différents matériaux.Of course, the invention is obviously not limited to the embodiment shown and described above, but covers all variants, particularly with regard to the shapes, nature and dimensions of the seal, which can for example be a cylinder head gasket. Similarly, the packaging device of the invention can have different shapes, dimensions, can be obtained by different techniques and can be made from different materials.
