  • the second motor 88 drives the rotation of the pusher wheel to cause the empty bobbin 10 to be caught in the pre-intubation mechanism 86 to prevent the empty bobbin 10 from falling, and then to advance the photoelectricity on the trolley 7.
  • the intubation control system operates the electromagnetic hoser 87 when the centerline of the empty bobbin 10 is aligned with the centerline of the spindle 22.
  • the empty bobbin 10 is accurately inserted into the spindle 22, and after the insertion, the cannula control system issues a reset command to move the electromagnetic hoser 87 back to the position before the tube.
  • the ring spinning intelligent doffer of the invention can realize automatic drawing of the full bobbin on the ring spinning machine, and can also automatically discharge the empty bobbin and insert it into the empty spindle of the ring spinning machine, which greatly improves the
  • the production efficiency of the ring spinning machine reduces the damage to the equipment during the drawing and intubation process, and it can be modified on the basis of the existing old ring spinning machine, so it has great market prospect and strong Industrial applicability.

Abstract

L'invention porte sur un dispositif détacheur automatique pour un métier à filer à anneau pour remplacer les tubes (10) sur le métier à filer à anneau (2), lequel dispositif comprend un tasseau détacheur (1). Le tasseau détacheur est disposé d'un côté du métier à filer à anneau. Un robot tridimensionnel (4) est disposé sur le tasseau détacheur, et un mécanisme d'extraction de tube non simultanée (5) est installé de façon fixe sur le robot. Le mécanisme d'extraction de tube non simultanée comprend une entretoise (51), et deux dispositifs d'extraction de tube fixes (52) sont disposés sur l'entretoise. Chaque dispositif d'extraction de tube fixe (6) comprend un bloc de liaison (53) et un bras mécanique (54). Des dispositifs d'extraction de tube réglables (55) sont disposés entre les deux dispositifs d'extraction de tube fixes. Chaque dispositif d'extraction de tube réglable comprend une plaque de limite supérieure (56) et une plaque de limite inférieure (57), et un rail de coulissement longitudinal (58) est relié entre la plaque de limite supérieure et la plaque de limite inférieure. Un bloc de coulissement longitudinal (59) est disposé sur le rail de coulissement, et un ressort de rappel (60) est disposé entre le bloc de coulissement longitudinal et la plaque de limite inférieure. Un bras mécanique pour saisir et enlever un tube est monté à demeure sur le bloc de coulissement longitudinal. Ce dispositif détacheur automatique a un rendement élevé d'extraction de tube, et peut empêcher la machine d'être endommagée.
