Description

       

      Dispositif    pour dévider en continu du fil à partir de fûts    L'utilisation de fûts pour     l'emmagasinage     de fil est connue. On connaît également déjà  des dispositifs permettant une réception en  continu du fil dans ces fûts.  



  Jusqu'à présent, par contre, il n'était pas       possible    de     dévider    plusieurs fûts successive  ment sans qu'il y ait lieu d'arrêter les machines  utilisant     ce    fil pour établir une soudure entre  les fils emmagasinés dans deux fûts successifs,  ce qui provoquait des     pertes    de temps et de  matériel par suite de formation de déchets, par  exemple dans le cas de la vulcanisation con  tinue.  



  La présente invention concerne un dispo  sitif palliant cet inconvénient.  



  Le dispositif selon l'invention pour dévider  en continu du fil à partir de fûts est caractérisé  en ce     qu'il        comporte    deux cônes de guidage,  tronqués en leur sommet et présentant chacun  une ouverture allant du sommet à la base, ces       ouvertures    étant reliées entre elles par deux       flasques    ménageant entre eux un passage, les  fûts d'alimentation étant placés chacun     coaxia-          lement    sous un cône.  



  Le dessin annexé représente, à titre d'exem  ple, une forme d'exécution du dispositif faisant  l'objet de l'invention.  



  La     fig.    1 en est une vue en perspective.  



  La     fig.    2 représente une vue en plan d'une  partie du dispositif.    La     fig.    3 représente un détail d'une partie  du     dispositif.     



  La     fig.    4 représente une vue de face d'un  fût muni d'un dispositif destiné à éviter la for  mation de boucles.    La     fig.    5 représente une section droite par  tielle du fût représenté à la     fig.    4.  



  Le dispositif comprend deux cônes de gui  dage 1 et 2     (fig.    1 et 2), tronqués en leurs som  mets 3, présentant chacun une ouverture 4 al  lant du sommet à la base. Deux flasques 5  reliant ces ouvertures ménagent entre eux un  passage permettant au fil dévidé de passer d'un  cône à l'autre. Deux fûts d'alimentation 6 et 7  se dévidant alternativement     (fig.    1) sont placés  chacun     coaxialement    sous un cône. Chaque fût  d'alimentation comporte une paroi extérieure  8 entourant un axe 9, le fil étant disposé entre  la paroi 8 et l'axe 9.     Eventuellement,    une ral  longe cylindrique 10 prolonge     l'axe    9.

   La ral  longe 10 porte un disque 11, mobile autour de  son axe et de diamètre supérieur à celui de  l'axe 9. On peut prolonger vers le haut la paroi  8 de chaque fût par un cylindre 12. Les deux  cônes sont surmontés par un rouleau 13 dis  posé de telle façon que le plan vertical passant  par le passage ménagé par les deux flasques 5  est tangent à ce rouleau. Une poulie 14, mon  tée mobile sur un bâti     sert    de renvoi pour le  fil.      Le fonctionnement du dispositif est le sui  vant : le fil emmagasiné dans le fût 6 est dé  vidé. Le disque 11 monté fou sur la rallonge  10 est entraîné en rotation par le frottement  tangentiel du fil en cas de tension accidentelle  de     celui-ci    et le dégage ensuite par son inertie.

    Il peut même être nécessaire, pour de très gran  des vitesses de dévidage du fil,     d'entrainer    en  rotation permanente le     disque    de telle façon  que sa vitesse tangentielle soit supérieure à la  vitesse du fil. Dans ce cas,     l'entraînement    du       disque    peut se faire au moyen d'un moteur  électrique placé à     l'intérieur    de la rallonge 10  ou, comme cela est représenté fi,-. 3, à l'aide  d'un jet d'air provenant d'une soufflerie 15  dirigé sur des pales 16 solidaires du disque.

   Le  cylindre 12 prolongeant la paroi extérieure 8  du fût est prévu pour éviter un ballonnement  du fil. -Le fil passant à l'intérieur du cône 1  passe autour du rouleau 13     mobile    sur son  axe, puis, renvoyé vers la poulie 14, va ensuite  vers la machine utilisatrice.  



  Pendant que le fût 6 se dévide, un fût plein  7 est mis en place sous le cône 2 et l'on relie  entre eux le bout inférieur du fût 6 et le bout  supérieur du fût 7 au moyen, par exemple,  d'une soudure 23. Lorsque la dernière spire  du fût 6 monte, le fil passe du cône 1 au cône  2 par le passage ménagé entre eux par les  flasques 5 et continue à se dévider à partir du  fût 7. Aucune intervention de l'opérateur n'est  nécessaire à ce moment et cette opération s'ef  fectue continuellement sans aucun ralentisse  ment du débit du dispositif d'alimentation.  



  Lorsque le fil que l'on dévide est un fil  souple composé de plusieurs brins, des bou  cles peuvent se former et provoquer dans les  stades ultérieurs de la fabrication des ruptures  qu'il faut éviter.  



       Afin    d'empêcher la formation de ces bou  cles,     il    faut, à tout moment, maintenir le fil  qui se dévide sous une certaine tension, faible       d'ailleurs.     



  Au cours du dévidage normal d'un fût, le  poids du fil et la présence dans le fût des spi  res du fil suffisent à lui appliquer     cette    tension,    mais, lorsque la dernière spire du fût est dé  vidée, le fil est alors parallèle au bout vertical  qui a été relié auparavant au bout supérieur du  fût suivant, et c'est à ce moment que le fil  peut. facilement se mettre en huit.  



  Pour supprimer cet     inconvénient,    -un four  reau 17 (fia. 4 et 5) destiné à     contenir    le bout  inférieur du fil enroulé dans un fût est assujetti  à l'intérieur de la paroi extérieure 8 de     ce    fût  au moyen de crochets à ressort 20 passant par  des trous 21 de la paroi 8. Ce     fourreau    est  muni, sur toute sa longueur, d'une fente laté  rale 18 fermée par une lame de ressort 19.     Il     comprend à sa base une goupille     amovible    22.

    Lors du     dévidage,    lorsque la dernière spire  monte, le fil remonte le long de la fente 18 du  fourreau 17 en étant retenu par la lame de res  sort 19 de telle sorte que le     fil    est maintenu  sous une tension suffisante pour éviter la for  mation de boucles.



      Device for continuously unwinding wire from drums The use of drums for storing yarn is known. Devices are also already known allowing continuous reception of the yarn in these drums.



  Until now, on the other hand, it was not possible to unwind several drums successively without having to stop the machines using this wire to establish a weld between the wires stored in two successive drums, which wastes time and material as a result of waste formation, for example in the case of continuous vulcanization.



  The present invention relates to a device overcoming this drawback.



  The device according to the invention for continuously unwinding wire from drums is characterized in that it comprises two guide cones, truncated at their top and each having an opening going from the top to the base, these openings being connected between they by two flanges leaving a passage between them, the feed drums each being placed coaxially under a cone.



  The appended drawing represents, by way of example, an embodiment of the device forming the subject of the invention.



  Fig. 1 is a perspective view.



  Fig. 2 shows a plan view of part of the device. Fig. 3 shows a detail of part of the device.



  Fig. 4 shows a front view of a barrel provided with a device intended to prevent the formation of loops. Fig. 5 shows a partial cross section of the barrel shown in FIG. 4.



  The device comprises two guiding cones 1 and 2 (Figs. 1 and 2), truncated at their summits 3, each having an opening 4 extending from the top to the base. Two flanges 5 connecting these openings provide a passage between them allowing the unwound wire to pass from one cone to another. Two feed drums 6 and 7 unwinding alternately (fig. 1) are each placed coaxially under a cone. Each supply barrel has an outer wall 8 surrounding an axis 9, the wire being disposed between the wall 8 and the axis 9. Optionally, a cylindrical extension 10 extends the axis 9.

   The extension 10 carries a disc 11, movable around its axis and of diameter greater than that of the axis 9. The wall 8 of each barrel can be extended upwards by a cylinder 12. The two cones are surmounted by a roller 13 arranged so that the vertical plane passing through the passage formed by the two flanges 5 is tangent to this roller. A pulley 14, my movable tee on a frame serves as a reference for the wire. The operation of the device is as follows: the wire stored in the drum 6 is emptied. The disc 11 mounted idle on the extension 10 is driven in rotation by the tangential friction of the wire in the event of accidental tension of the latter and then releases it by its inertia.

    It may even be necessary, for very high wire unwinding speeds, to drive the disc in permanent rotation so that its tangential speed is greater than the speed of the wire. In this case, the drive of the disc can be done by means of an electric motor placed inside the extension 10 or, as shown in fi, -. 3, using a jet of air from a blower 15 directed onto blades 16 integral with the disk.

   The cylinder 12 extending the outer wall 8 of the barrel is provided to prevent ballooning of the wire. -The wire passing inside the cone 1 passes around the roller 13 movable on its axis, then returned to the pulley 14, then goes to the user machine.



  While the barrel 6 unwinds, a full barrel 7 is placed under the cone 2 and the lower end of the barrel 6 and the upper end of the barrel 7 are connected between them by means, for example, of a weld 23. When the last turn of the barrel 6 rises, the wire passes from the cone 1 to the cone 2 through the passage formed between them by the flanges 5 and continues to unwind from the barrel 7. No operator intervention is required. necessary at this time and this operation is carried out continuously without any slowing down of the flow rate of the feed device.



  When the wire which is unwound is a flexible wire composed of several strands, slugs can form and cause in the later stages of the manufacture breaks which must be avoided.



       In order to prevent the formation of these loops, it is necessary, at all times, to maintain the thread which unwinds under a certain tension, which is also weak.



  During normal unwinding of a barrel, the weight of the wire and the presence in the barrel of the turns of the wire are sufficient to apply this tension to it, but, when the last turn of the barrel is unloaded, the wire is then parallel to the vertical end that was previously connected to the upper end of the next barrel, and that's when the wire can. easily go into eight.



  To overcome this drawback, a ring oven 17 (fig. 4 and 5) intended to contain the lower end of the wire wound in a barrel is secured inside the outer wall 8 of this barrel by means of spring hooks 20 passing through holes 21 in the wall 8. This sheath is provided, over its entire length, with a lateral slot 18 closed by a leaf spring 19. It comprises at its base a removable pin 22.

    During unwinding, when the last turn rises, the wire rises along the slot 18 of the sheath 17 while being retained by the spring blade 19 so that the wire is maintained under sufficient tension to prevent the formation of loops.
