Description
La présente invention concerne un dispositif particulier pour le soudage, par contact, d'une pièce additionnelle sur une surface plane d'un article moulé, la pièce additionnelle et l'article moulé étant réalisés en des matières thermoplastiques thermosoudables entre elles. The present invention relates to a particular device for welding, by contact, an additional part on a flat surface of a molded article, the additional part and the molded article being made of thermoplastic materials which can be heat-welded together.
Pour assurer le soudage de pièces additionnelles telles que des rondelles, des éléments de fixation, des goulots, etc. sur une surface plane d'un article moulé tel que, par exemple, un réservoir pour carburant moulé par soufflage, on utilise généralement la technique de soudage par contact appelée également technique de soudage par miroir ou par outil chauffant. To weld additional parts such as washers, fasteners, necks, etc. on a flat surface of a molded article such as, for example, a blast-molded fuel tank, the contact welding technique is also generally used, also called mirror or heating tool welding technique.
Selon cette technique, on amène un outil chauffant contre la surface plane de l'article moulé devant recevoir la pièce additionnelle de façon à porter cette surface à la température requise pour le soudage. Lorsque cette température est atteinte, on retire l'outil chauffant et on applique sous pression la pièce additionnelle contre cette surface, la pièce additionnelle étant également #préchauffée à la température requise en vue de son soudage. En général, le chauffage de la surface plane de l'article moulé et de la pièce additionnelle est assuré de façon simultanée par un seul outil chauffant qui est interposé entre et en contact avec cette surface .et la pièce additionnelle. According to this technique, a heating tool is brought against the flat surface of the molded article which is to receive the additional part so as to bring this surface to the temperature required for welding. When this temperature is reached, the heating tool is removed and the additional part is pressed against this surface, the additional part also being # preheated to the temperature required for welding. In general, the heating of the flat surface of the molded article and of the additional part is provided simultaneously by a single heating tool which is interposed between and in contact with this surface and the additional part.
Dans les dispositifs exploitant cette technique, l'outil chauffant est généralement amené contre la surface plane de l'article moulé maintenu fixe selon une trajectoire qui est perpendiculaire à la surface de l'article moulé. En conséquence, pour assurer une fusion superficielle régulière et homogène de la surface de l'article moulé et partant une soudure de qualité, il importe d'imposer un parallélisme parfait entre la surface de l'article moulé et la surface utile de l'outil chauffant durant et après le déplacement de l'outil chauffant. In devices exploiting this technique, the heating tool is generally brought against the flat surface of the molded article kept fixed along a path which is perpendicular to the surface of the molded article. Consequently, to ensure a regular and homogeneous surface fusion of the surface of the molded article and hence a quality weld, it is important to impose a perfect parallelism between the surface of the molded article and the useful surface of the tool. heating during and after moving the heating tool.
Or, dans de nombreux cas d'application ce parallélisme ne peut être assuré de façon certaine. Ainsi, par exemple, dans le cas du soudage d'une pièce additionnelle sur des articles moulés par extrusion-soufflage, il n'est pas possible de garantir une constance absolue de forme et de dimensions des articles successifs moulés et, en conséquence, la position réelle de la surface appelée à recevoir la pièce additionnelle peut s'écarter dans une certaine mesure du plan de référence choisi pour l'outil chauffant. However, in many cases of application, this parallelism cannot be guaranteed with certainty. Thus, for example, in the case of the welding of an additional part on articles molded by extrusion blow molding, it is not possible to guarantee an absolute constancy of shape and dimensions of the successive molded articles and, consequently, the actual position of the surface required to receive the additional part may deviate to a certain extent from the reference plane chosen for the heating tool.
Il a maintenant été réalisé un dispositif de soudage par contact dans lequel il n'est plus nécessaire d'assurer initialement un parallélisme strict entre la surface plane de l'article moulé devant recevoir la pièce additionnelle et la surface utile de l'outil chauffant pour obtenir une soudure de qualité. A contact welding device has now been produced in which it is no longer necessary to initially ensure strict parallelism between the flat surface of the molded article which is to receive the additional part and the useful surface of the heating tool for get a quality weld.
La présente invention concerne, dès lors, un dispositif pour le soudage, par contact, d'une pièce additionnelle sur une surface plane d'un article moulé, la pièce additionnelle et l'article moulé étant réalisés en des matières thermoplastiques thermosoudables entre elles, comportant un outil chauffant déplaçable au moyen d'un organe de commande et équipé d'au moins un élément de chauffage plan, ledit élément de chauffage plan pouvant être amené temporairement en contact avec la surface plane de l'article moulé de façon à porter cette surface à la température requise pour le soudage de la pièce additionnelle et un moyen pour appliquer, sous pression, la pièce additionnelle, préchauffée à la température requise pour son soudage, sur la surface plane de l'article moulé après retrait de l'élément chauffant plan de cette surface caractérisé en ce que l'élément chauffant plan est monté sur l'outil chauffant par l'intermédiaire d'une liaison permettant librement une orientation multiplanaire de cet élément lors de son contact avec la surface plane de l'article moulé devant recevoir la pièce additionnelle. The present invention therefore relates to a device for welding, by contact, an additional part on a flat surface of a molded article, the additional part and the molded article being made of heat-sealable thermoplastic materials, comprising a heating tool movable by means of a control member and equipped with at least one planar heating element, said planar heating element being able to be brought temporarily into contact with the planar surface of the molded article so as to carry this surface at the temperature required for welding the additional part and a means for applying, under pressure, the additional part, preheated to the temperature required for its welding, on the flat surface of the molded article after removal of the heating element plane of this surface characterized in that the planar heating element is mounted on the heating tool by means of a connection allowing freely a multiplanar orientation of this element during its contact with the flat surface of the molded article to receive the additional part.
La liaison entre l'élément chauffant plan et l'outil chauffant peut être quelconque pour autant que celle-ci autorise une orientation multiplanaire de cet élément dès son contact avec la surface plane de l'article moulé. Ainsi, par exemple, cette liaison peut être assurée par une pluralité de ressorts de compression équilibrés. The connection between the planar heating element and the heating tool can be arbitrary, provided that this authorizes a multiplanar orientation of this element as soon as it comes into contact with the planar surface of the molded article. Thus, for example, this connection can be ensured by a plurality of balanced compression springs.
Selon un mode de réalisation qui est préféré, ltélément chauffant plan est monté sur l'outil chauffant par l'intermédiaire d'une articulation à rotule sphérique. A cet effet, par exemple, l'outil chauffant peut être équipé d'une tige terminée par une tête sphérique qui est logée dans un logement sphérique correspondant prévu dans la partie arrière de l'élément chauffant plan. Il convient évidemment de prévoir un jeu adéquat entre la tête sphérique et le logement sphérique de façon telle que l'élément chauffant plan puisse pivoter librement sur la tête sphérique nonobstant les dilatations thermiques. According to an embodiment which is preferred, the flat heating element is mounted on the heating tool by means of a spherical ball joint. For this purpose, for example, the heating tool can be equipped with a rod terminated by a spherical head which is housed in a corresponding spherical housing provided in the rear part of the planar heating element. It is obviously necessary to provide an adequate clearance between the spherical head and the spherical housing so that the planar heating element can pivot freely on the spherical head notwithstanding the thermal expansions.
La position du logement sphérique dans l'élément chauffant plan est, de préférence, choisie, en fonction du centre de gravité de l'élément chauffant plan, de façon telle qu'en position de repos, la surface utile de l'élément chauffant plan soit substantiellement perpendiculaire à l'axe longitudinal de la tige équipée de la tête sphérique. The position of the spherical housing in the planar heating element is preferably chosen as a function of the center of gravity of the planar heating element, so that in the rest position, the useful surface of the planar heating element is substantially perpendicular to the longitudinal axis of the rod equipped with the spherical head.
Selon un mode de réalisation du dispositif selon l'invention qui est également préféré, l'outil chauffant présente une surface de chauffage appropriée qui est opposée à l'élément chauffant plan, cette surface de chauffage étant exploitée pour amener, à la température requise pour son soudage, la surface de la pièce additionnelle devant être soudée sur l'article moulé tandis que l'élément chauffant plan est amené simultanément en contact avec la surface plane de l'article moulé devant recevoir la pièce additionnelle. Cette surface de chauffage peut si on le souhaite être également constituée par un élément chauffant plan qui est monté sur l'outil chauffant de la même façon que celui utilisé pour porter à température requise la surface de l'article moulé devant recevoir la pièce additionnelle. According to an embodiment of the device according to the invention which is also preferred, the heating tool has a suitable heating surface which is opposite to the planar heating element, this heating surface being used to bring the temperature required for its welding, the surface of the additional part to be welded to the molded article while the planar heating element is brought simultaneously into contact with the planar surface of the molded article to receive the additional part. This heating surface can, if desired, also consist of a planar heating element which is mounted on the heating tool in the same way as that used to bring the surface of the molded article to receive the additional part to the required temperature.
Selon une autre variante de réalisation qui peut également se révéler avantageuse, le moyen pour appliquer, sous pression, la pièce additionnelle préchauffée contre la surface plane de l'article moulé est également équipé d'une liaison permettant librement une orientation multiplanaire de la pièce additionnelle préchauffée lors de son contact avec la surface plane de l'article moulé devant recevoir cette pièce additionnelle. Cette liaison peut notamment être également assurée par l'intermédiaire d'une articulation à rotule sphérique. According to another alternative embodiment which may also prove to be advantageous, the means for applying, under pressure, the additional preheated part against the flat surface of the molded article is also equipped with a connection allowing free multiplanar orientation of the additional part preheated upon contact with the flat surface of the molded article to receive this additional part. This connection can in particular be also ensured by means of a spherical ball joint.
Dans le dispositif conforme à l'invention, l'outil chauffant et l'élément chauffant plan sont réalisés en des matériaux conducteurs de la chaleur et, en particulier, en métal et sont, en outre, équipés de moyens internes de chauffage tels que des résistances de chauffage électrique et de moyens de régulation tels que des sondes thermiques contrôlant l'alimentation des moyens de chauffage. In the device according to the invention, the heating tool and the planar heating element are made of heat-conducting materials and, in particular, of metal and are also equipped with internal heating means such as electric heating resistors and regulating means such as thermal probes controlling the supply of the heating means.
Le dispositif de soudage par contact conforme à l'invention comporte évidemment un châssis, des moyens de fixation temporaire de l'article moulé devant recevoir la pièce additionnelle et des moyens de commande et de contrôle des déplacements de l'outil chauffant et du moyen pour appliquer la pièce additionnelle sous pression contre l'article moulé, tous ces éléments étant réalisés de façon classique connue en soi. The contact welding device according to the invention obviously comprises a chassis, means for temporarily fixing the molded article to receive the additional part and means for controlling and controlling the movements of the heating tool and the means for applying the additional piece under pressure against the molded article, all these elements being produced in a conventional manner known per se.
Le dispositif de soudage par contact conforme à l'invention et son fonctionnement sont, par ailleurs, explicités plus en détail dans la description qui va suivre d'un mode particulier de réalisation. Dans cette description, on se réfèrera aux figures des dessins annexés dans lesquels - la fig. l est une vue en coupe de l'outil chauffant en position
de repos.The contact welding device according to the invention and its operation are, moreover, explained in more detail in the description which follows of a particular embodiment. In this description, reference will be made to the figures of the appended drawings in which - FIG. l is a sectional view of the heating tool in position
rest.
- la fig. 2 est une vue en coupe du même outil en position de
travail.- fig. 2 is a sectional view of the same tool in the position of
job.
Par souci de clarté, dans les figures, on n'a représenté que l'outil chauffant équipant le dispositif de soudage, les autres éléments constitutifs du dispositif étant classiques et ne nécessitant dès lors ni une représentation, ni une description particulière pour la bonne compréhension de la présente invention. For the sake of clarity, in the figures, only the heating tool fitted to the welding device has been shown, the other constituent elements of the device being conventional and therefore requiring neither a representation nor a particular description for good understanding. of the present invention.
Ainsi qu'il apparaît sur les figures, l'outil chauffant l est constitué d'un corps métallique 2 et d'un élément de chauffage plan 3 également métallique. Le corps métallique 2 de forme générale cylindrique, comporte à sa base une surface plane de chauffage 4 et est, en outre, équipé dans sa partie centrale supérieure d'une tige métallique 5 débordante pourvue à son extrémité d'une tête sphérique 6. As it can be seen in the figures, the heating tool 1 consists of a metallic body 2 and a planar heating element 3 also metallic. The metallic body 2 of generally cylindrical shape, has at its base a flat heating surface 4 and is, in addition, equipped in its upper central part with a projecting metal rod 5 provided at its end with a spherical head 6.
Le corps métallique 2 contient également des résistances électriques de chauffage 7 et une ou plusieurs sondes thermiques, non représentées. The metal body 2 also contains electrical heating resistors 7 and one or more thermal probes, not shown.
Le corps métallique 2 est enfin équipé latéralement d'une gaine en matériau thermoisolant 8 qui est elle-même entourée d'un support métallique, non représenté, qui le relie au mécanisme de commande des déplacements de l'outil chauffant 1. The metal body 2 is finally fitted laterally with a sheath made of heat-insulating material 8 which is itself surrounded by a metal support, not shown, which connects it to the mechanism for controlling the movements of the heating tool 1.
L'élément de chauffage plan 3 comporte à sa partie supérieure une surface utile de chauffe plane 9 équipée en sa partie centrale d'un téton de centrage 10. The planar heating element 3 has at its upper part a useful planar heating surface 9 equipped in its central part with a centering stud 10.
L'élément de chauffage plan 3 comporte à sa partie arrière un logement sphérique il pour la tête sphérique 6, la tête sphérique 6 étant retenue contre ce logement par une bague à siège sphérique 12 maintenue en place par une rondelle de blocage 13. La tête sphérique 6 et le logement sphérique il sont dimensionnés de façon telle que l'élément de chauffage plan 3 puisse pivoter librement en tout sens autour de la tête sphérique 6. The planar heating element 3 has at its rear part a spherical housing il for the spherical head 6, the spherical head 6 being retained against this housing by a spherical seat ring 12 held in place by a locking washer 13. The head spherical 6 and the spherical housing they are dimensioned in such a way that the planar heating element 3 can pivot freely in any direction around the spherical head 6.
En outre, l'élément de chauffage plan 3 et le logement sphérique li sont réalisés de façon telle que le centre de gravité de l'élément de chauffage plan 3 soit situé nettement en dessous du centre de la tête sphérique 6 et, dès lors, en position de repos (fig. 1), l'élément de chauffage plan 3 est disposé en équilibre sous la tige métallique 5 de-façon telle que sa surface utile de chauffage 9 est sensiblement perp#endiculaire à l'axe longitudinal de la tige métallique 5. In addition, the planar heating element 3 and the spherical housing li are produced in such a way that the center of gravity of the planar heating element 3 is located clearly below the center of the spherical head 6 and, consequently, in the rest position (fig. 1), the flat heating element 3 is placed in equilibrium under the metal rod 5 so that its useful heating surface 9 is substantially perp # endicular to the longitudinal axis of the rod metallic 5.
L'élément chauffant plan 3 comporte encore des résistances électriques de chauffage 14 et une ou plusieurs sondes thermiques non représentées. The planar heating element 3 also includes electrical heating resistors 14 and one or more thermal probes, not shown.
Le fonctionnement du dispositif ainsi décrit est le suivant. The operation of the device thus described is as follows.
En position de repos, l'outil chauffant se trouve dans la position équilibrée représentée à la fig. l et un article moulé 15 à pourvoir d'une pièce additionnelle est amené dans un cadre de serrage non representé et maintenu dans une position telle que par exemple la paroi de l'article moulé 15 n'est pas parallèle à la surface utile de chauffe plane 9 de l'élément de chauffage plan 3. In the rest position, the heating tool is in the balanced position shown in fig. l and a molded article 15 to be provided with an additional part is brought into a clamping frame not shown and kept in a position such that for example the wall of the molded article 15 is not parallel to the useful heating surface plane 9 of the heating element plane 3.
En vue de réaliser la soudure de la pièce additionnelle sur l'article moulé 15 l'outil chauffant 1 est d'abord amené par l'intermédiaire de son mécanisme de commande en direction de la paroi de l'article moulé. In order to weld the additional piece on the molded article, the heating tool 1 is first brought through its control mechanism towards the wall of the molded article.
Lors de ce déplacement qui est orthogonal à la paroi de l'article moulé une partie de la surface utile de chauffe plane 9 entre en contact avec la paroi de l'article moulé 15 et dès cet instant l'élément de chauffage plan 3 pivote progressivement autour de la tête sphérique 6 de façon telle que la surface utile de chauffe plane 9 se dispose finalement parfaitement et entièrement contre la paroi de l'article moulé 15 et peut ainsi assurer un chauffage superficiel homogène de cette paroi en vue du soudage désiré. During this movement which is orthogonal to the wall of the molded article, part of the useful flat heating surface 9 comes into contact with the wall of the molded article 15 and from this instant the planar heating element 3 gradually pivots around the spherical head 6 so that the useful planar heating surface 9 finally settles perfectly and entirely against the wall of the molded article 15 and can thus ensure a uniform surface heating of this wall for the desired welding.
Tandis que la surface utile de chauffe plane 9 effectue son travail, un moyen, non représenté, amène la pièce additionnelle, également non représentée, contre la surface plane de chauffage 4 équipant le corps métallique 2 de l'outil chauffant 1 et cette pièce additionnelle est, dès lors, portée simultanément à la température de soudage requise. While the useful flat heating surface 9 performs its work, a means, not shown, brings the additional part, also not shown, against the flat heating surface 4 fitted to the metal body 2 of the heating tool 1 and this additional part. is therefore brought simultaneously to the required welding temperature.
Dès que la paroi de l'article moulé 15 et la pièce additionnelle ont atteint la température requise, l'outil chauffant 1 est écarté de l'article moulé et de la pièce addditionnelle et le moyen d'amenée de la pièce additionnelle applique celle-ci sous pression contre la paroi de l'article moulé durant un temps suffisant pour assurer le soudage souhaité. As soon as the wall of the molded article 15 and the additional part have reached the required temperature, the heating tool 1 is moved away from the molded article and from the additional part and the means of supplying the additional part applies this. ci under pressure against the wall of the molded article for a sufficient time to ensure the desired welding.
Dans le mode de réalisation illustré l'article moulé 15 présente une perforation 16 (fig. 1) souhaitée et venue de moulage et cette perforation 16 est exploitée via le téton de centrage 10 pour assurer en outre un centrage idéal de l'élément de chauffage plan 3 lors de son amenée en contact avec la paroi de l'article moulé 15. In the illustrated embodiment, the molded article 15 has a desired perforation 16 (fig. 1) which has been molded and this perforation 16 is used via the centering pin 10 to further ensure ideal centering of the heating element. plane 3 when brought into contact with the wall of the molded article 15.
