  • the present invention relates to a winding device for winding up a spinning thread and a method for winding up a spinning thread.
  • the thread can be guided back and forth at a constant distance from a spool surface by a thread guide means.
  • the distance between the thread guide means and the respective spool determines a so-called dragging of the thread and leads to a so-called drag curve.
  • Such entrainment represents the difference between the respective guiding position of the thread guide means and the point of contact of the thread on the bobbin surface. This entrainment results in a free thread length, which is also referred to as the drag length.
  • Knock-offs are thread sections that emerge from the end faces of the cylindrical spool and can lead to disruptions in the thread's flow in a further processing process.
  • the object of the present invention was to provide a winding device for winding up a spinning thread, with which spinning threads can be wound into bobbin packages which, even with varying laying angles, ensure the most uniform possible distribution of mass over a storage width or stroke width of a spinning thread on a thread storage surface Coil or the coil package.
  • the task was also to provide a method for winding a spinning thread, with which spinning threads can be wound into bobbin packs, which have the most uniform possible mass distribution over a storage width or stroke width of a spinning thread on a thread storage surface of the bobbin or the bobbin pack, even with varying laying angles.
  • a first aspect of the present invention relates to a winding device for winding a spinning thread, in particular a melt-spun thread made of a plurality of filaments.
  • a winding device for winding a spinning thread in particular a melt-spun thread made of a plurality of filaments, comprises a winding spindle through which at least one spinning thread can be wound onto a bobbin tube to form a bobbin package.
  • the winding device has at least one traversing device, through which a spinning thread can be guided back and forth along a traversing stroke and in a resulting stroke width can be wound on a rotating bobbin or a rotating bobbin package.
  • the winding device has at least two thread stops for changing the thread movement when the stroke of the traversing device is reversed.
  • thread stops for changing the thread movement when the stroke of the traversing device is reversed.
  • the winding device comprises a drive device for adjusting the position of the at least two thread stops in opposite directions.
  • the stroke width that occurs when a spinning thread is placed on a rotating bobbin or on a bobbin can be increased.
  • the stroke width can be reduced or reduced. Thread stops arranged or adjustable in this way enable a particularly uniform distribution of mass over a storage width or stroke width of a spinning thread on a thread storage surface of a spool.
  • the traversing device can preferably be designed as a so-called wing traversing or birotor traversing with two traversing wing arms.
  • the traversing stroke can be limited in one direction by a stroke reversal of the traversing device or in both traversing directions by a stroke reversal.
  • the stroke width can be changed, which results when the spinning thread is wound on a bobbin tube or on a bobbin package. For example, due to a change in the diameter of a spool, a change in a drag curve or the laying angle on the thread storage surface can result. Because an increase in the diameter of the spool also changes the drag curve and thus also the stroke width of the thread on the spool.
  • a constant stroke width can be ensured throughout the entire winding process of a bobbin, whereby the mass of the spinning thread on the bobbin can also be distributed evenly.
  • a change in the stroke width of the thread due to a changing drag curve or a varying laying angle can be compensated for in a suitable manner by adjusting the position of the thread stops in opposite directions.
  • the thread stops can be designed as reversing auxiliary devices and/or as a stroke width changing device.
  • a uniform distribution of mass over the stroke width of a spinning thread on a thread storage surface on a spool package or on a spool can be achieved in a particularly advantageous manner. It is also possible to avoid the occurrence of so-called knock-offs with further increased security.
  • the thread stops can be designed and/or arranged for contacting by a spinning thread when and/or before reaching a stroke reversal of the traversing device which forms one end of the traversing stroke. This means that a spinning thread can already contact a thread stop after a stroke reversal of the traversing device. This affects the thread movement in the area of a stroke reversal and thus also on the precision of the thread winding. In this way, a mass distribution can be suitably improved over the stroke width of a spinning thread on a thread storage surface.
  • the thread stops can each be designed and/or arranged to produce a quick reversal of a spinning thread in a stroke reversal of the traversing device. A quick reversal supports the traversing device in reversing the direction of the spinning thread, so that the direction can be changed more quickly. This makes it possible to influence the actual stroke width of the thread on the respective spool in a particularly preferred manner.
  • the thread stops can also be designed and/or arranged for contacting by a spinning thread in its running direction in front of and/or above the traversing device.

  • the at least two thread stops can be designed to change the thread movement in two opposite stroke reversal areas of the traversing device. In this way, a change in the stroke width of the spinning thread can advantageously be carried out symmetrically on the respective spool.

  • Such a linear movement can directly influence the stroke width of a spinning thread placed on the respective spool.
  • the drive device can be designed for the opposite position adjustment of more than two thread stops, in particular more than two pairs of thread stops.
  • several pairs of thread stops for changing the thread movement can be designed and / or arranged in two opposite stroke reversal areas of several traversing devices. Suitable adjustment measures can therefore be carried out by the respective thread stops at several winding points or at several spools to be wound in order to produce a change in the stroke width of the spinning thread to be wound.
  • the thread stops can each be designed as a thread contact pin and/or each have a thread contact pin.
  • An adjustable thread limiting pin can be used to provide a suitable contact surface for the respective spinning thread and thus, for example, to avoid the formation of knock-offs with a high degree of certainty and/or to achieve a change in the stroke width with a high degree of certainty. Thread limiting pins also require little structural effort and are inexpensive to produce.
  • the thread contact pin preferably has a replaceable ceramic sleeve on the section that comes into engagement and contact with the spinning thread.
  • the ceramic sleeve is attached to the thread contact pin, for example by means of a screw connection which extends in the longitudinal extent of the thread contact pin.
  • the winding device can have two stop supports, in particular two support plates, for the thread stops and/or thread contact pins.
