  • a generic device for winding a thread on a spool is known from DE 4 432 498 AI.
  • the device has several cross-wound bobbins which are rotatably mounted on an axis of rotation.
  • Each cross-wound bobbin is assigned a thread guide unit, which in turn is axially displaceable in a guide.
  • a winding of the thread on the package is achieved in that the package is rotated about its central axis and the thread guide device is moved back and forth in an axial movement.
  • the object of the invention is to provide an improved device for winding a thread on a bobbin.
  • An advantage of the device according to the invention is that a linear drive with an anti-displacement rod in the form of a hollow shaft motor is used as the drive means.

  • the control unit controls the frequency converter in the manner and- manner, 'that the drive rod moves the yarn guiding unit in the desired manner.
  • the thread guide unit is coupled to two spring elements in such a way that the spring elements ' absorb the kinetic energy of the thread guide unit before a reversal of movement and after the movement reversal give the stored kinetic energy back to the thread guide unit. In this way, on the one hand, a damping of the movement speed of the thread guide unit in the reversal area is achieved and, moreover, the kinetic energy absorbed can be fed in. This enables gentle and low-energy movement of the thread guide unit. At the same time, the spring elements enable a quick reversal of movement. '
  • the control unit preferably reduces the speed of the thread guide unit before the movement reversal and thus ensures a gentle change in movement of the thread guide unit. This enables a low-vibration and gentle movement of the thread guide unit.
  • the drive shaft is guided via a sealing element into a housing of the hollow shaft motor, the sealing element being designed as dust protection. In this way it is avoided that the interior of the hollow shaft motor gets too dusty. This ensures a long service life for the hollow shaft motor.
  • the sealing element is designed in the form of a sealing labyrinth. Training as a sealing labyrinth offers relatively good dust protection and is inexpensive.
  • the dust protector is designed in the form of an overpressure device which blows air out of the housing in the region of the sealing gap between the housing and the drive rod.
  • the sealing element is preferably designed in the form of a hollow ring with blowing openings which are arranged in a ring around the drive train on an outside of the housing. In this way, a concentration of the air flow is concentrated on the required area. This avoids the unnecessary generation of excess pressure. This enables the device to be operated with little energy.
  • the blowing openings are arranged in a blowing direction, which are arranged in the direction of the drive rod and are directed at least slightly away from the housing.
  • this cleans the drive rod itself of dust and also generates an air flow that blows the dust away from the housing.

Abstract

L'invention concerne un dispositif d'enroulement d'un fil sur une bobine, comportant une unité de guidage de fil destinée à guider le fil, pouvant se déplacer axialement. Ladite unité de guidage de fil est reliée à un moteur à arbre creux servant de moyen d'entraînement. Ledit moteur à arbre creux comporte une barre d'entraînement conférant à l'unité de guidage de fil un mouvement de va-et-vient, avec des points de retour, de vitesse souhaitée, en fonction de la commande du moteur à arbre creux. Ledit moteur à arbre creux est un mode de réalisation particulièrement simple de moyen d'entraînement de l'unité de guidage de fil. D'autres modes de réalisation avantageux concernent l'étanchéification de la barre d'entraînement par rapport au carter du moteur à arbre creux. Un courant d'air opposé au moteur à arbre creux, dirigé vers la barre d'entraînement, est de préférence créé afin d'éviter que des poussières ne pénètrent dans le moteur à arbre creux.
