  • the yarn Y can be fed from the winding side 230R of the yarn accumulating portion 230 toward the unwinding side 230F while holding the yarn. Therefore, the stored yarn layer is not entangled, the fluff and the fluff are entangled, and sluffing does not occur when the yarn is unwound. Further, when the winding unit 50 unwinds the yarn Y from the yarn storage unit 230, the yarn does not break.
  • the pull-out unit 150 pulls out the yarn end from the yarn storage unit 230, the stored yarn Y is not entangled. Therefore, when the yarn end wound around the yarn storage unit 230 is sucked and pulled out, the yarn There is no occurrence of a drawing failure due to Y entanglement.
  • the yarn winding device of the present invention is industrially useful because it can prevent the occurrence of drawing failure due to yarn entanglement when the yarn end wound on the yarn storage body is sucked and pulled out.

Abstract

La présente invention se rapporte à un dispositif d'enroulement de fil qui peut empêcher l'apparition d'affaissement. Une unité d'enroulement (10), pendant l'élimination des défauts de filetage d'une bobine d'alimentation en fil (B1) autour de laquelle est enroulé un fil (Y) qui est filé à l'aide d'une machine de filage fin, enroule un paquet (P). L'unité d'enroulement (10) comprend un dispositif de stockage de fil (100) qui enroule le fil (Y) depuis la bobine d'alimentation en fil (B1) et stocke le fil enroulé. Le dispositif de stockage de fil (100) comprend les éléments suivants : un élément de stockage de fil (130) qui stocke le fil (Y) ; et un élément d'enroulement (140) qui, lors de la rotation, enroule le fil (Y) autour de l'élément de stockage de fil (130). L'élément de stockage de fil (130) comprend les éléments suivants : un corps de stockage de fil (côté extérieur de courroie) (132F) autour duquel le fil (Y) est enroulé ; et une poulie d'entraînement (134) qui maintient un espace équidistant entre les fils (Y) à enrouler et achemine le fil (Y) qui est enroulé autour du côté extérieur de courroie (132F) depuis un côté enroulement (130R) vers un côté libération (130F).
