Description


  
 



  Appareil pour la fermeture, au moyen d'un soudage par ultra-sons,
 d'une extrémité de tubes en matière plastique
 La revendication du brevet principal décrit un appareil pour la fermeture, au moyen   d'un    soudage par ultrasons, d'une extrémité de tubes en matière plastique, comprenant une matrice génératrice d'ultra-sons et une enclume, ces pièces venant serrer entre elles ladite extrémité des tubes pour le soudage, caractérisé en ce que la matrice comprend des saillies et l'enclume présente des gorges en regard des saillies et de forme complémentaire à celles-ci, le profil des saillies et des gorges permettant de donner à ladite extrémité des tubes une section en V qui s'inscrit dans la circonférence extérieure des tubes quand la matrice vient appuyer contre les tubes pour le soudage,

   et en ce qu'il comprend un guide soutenant les tubes à distance de l'enclume et présentant des gorges alignées avec celles de l'enclume pour que les tubes se présentent correctement dans celle-ci, et un organe de pression élastique agencé pour venir presser les tubes sur le guide au moment du soudage afin que le guide absorbe la vibration ultrasonique et l'empêche de se propager le long des tubes au-delà du guide.



   La présente invention concerne une nouvelle forme d'exécution de cet appareil.



   L'appareil selon l'invention pour la fermeture, au moyen d'un soudage par ultra-sons, d'une extrémité de tubes en matière plastique, selon la revendication du brevet principal, est caractérisé en ce que le guide est constitué par au moins une bande transporteuse en matière élastique comportant des gorges transversales dans lesquelles sont placés les tubes, et en ce que l'organe de pression élastique absorbant la vibration ultrasonique est constitué par les nervures élastiques de la bande délimitant ces gorges.



   La figure unique du dessin annexé est une vue en perspective d'une forme d'exécution de l'appareil, donnée à titre d'exemple.



   L'appareil représenté comprend un bâti 1 portant une trémie inclinée 2, une station de remplissage 3 et une station d'aspiration 4 coopérant pour le remplissage de tubes 5. Le bâti porte également une matrice 6 génératrice d'ultra-sons, une enclume 6' et des cylindres 7 et 8 pouvant tourner sous l'action d'un moteur non représenté. Les cylindres 7 et 8 portent quatre bandes 9 en matière élastique, du caoutchouc par exemple, qui sont entraînées par les cylindres 7 et 8 dans le sens de la flèche 10. Les bandes 9 sont crénelées, comportant des gorges 11 et des nervures 12.



   L'appareil fonctionne comme suit. Quand les bandes 9 sont en mouvement, les tubes 5 placés sur la trémie 2 pénètrent successivement dans une gorge 11 de chacune des bandes 9, ces gorges étant exactement alignées dans les quatre bandes. L'alignement exact des gorges des quatre bandes est assuré par un tambour d'entraînement non représenté, cannelé et   d'une    seule pièce, chaque dent du tambour pénétrant en même temps dans les gorges des quatre bandes qui sont ainsi entraînées en synchronisme. Le tambour est animé d'un mouvement rotatif intermittent, transmettant aux bandes des mouvements d'avance alternés avec des périodes de repos. A l'endroit où les bandes 9 sont courbées sur le cylindre 7, les nervures 12 s'écartent les unes des autres par suite de cette courbure et sont séparées alors d'une distance légèrement supérieure au diamètre externe des tubes.



  Ceux-ci pénètrent ainsi facilement dans les gorges. Ils sont ensuite serrés par les nervures 12 dans la partie rectiligne des bandes 9 entre les cylindres 7 et 8.



   Le mouvement des bandes est interrompu automatiquement quand deux tubes 5 se trouvent en regard des stations 3 et 4. Des aiguilles 13 dans la section de remplissage 3 pénètrent dans une extrémité des tubes 5 pendant que des aiguilles 14 de la section d'aspiration 4 pénètrent dans l'autre extrémité des mêmes tubes. Une soupape s'ouvre alors dans chacune des stations 3 et 4, reliant respectivement les aiguilles 13 à une source du liquide destiné à remplir les tubes, et les aiguilles 14 à  une source de vide produisant une aspiration dans les tubes. Ceux-ci sont ainsi remplis du liquide et les aiguilles 13 et 14 se retirent des tubes.



   Quand deux tubes sont en regard des stations 3 et 4, deux autres tubes déjà remplis sont en regard de la matrice 6. Celle-ci s'abaisse sur les tubes en les pinçant entre elle et l'enclume 6' pour former la soudure à l'extrémité correspondante des tubes, cette enclume se soulevant quand la matrice descend. Les nervures 12 délimitant les gorges 11 des bandes constituent un organe de pression élastique qui presse les tubes afin d'absorber la vibration ultrasonique et de l'empêcher de se propager le long des tubes. Les tubes soudés sont entraînés ensuite par les bandes 9 et quand celles-ci passent sur le cylindre 8, les nervures s'écartent suffisamment pour laisser tomber les tubes remplis dans un récipient non représenté.



   Le mouvement des bandes 9 est donc intermittent. Le temps d'arrêt des tubes devant les stations 3 et 4 et audessous de la matrice 6 peut être de   571100e    de seconde, le mouvement d'avance des bandes entre ces arrêts pouvant se faire pendant   43/100e    de seconde.



   Notons que c'est pour la clarté du dessin que les tubes 5 n'ont été représentés qu'entre les stations 3 et 4 d'une part et la matrice 6 d'autre part.
