Definitions

  • the present invention relates to a thread guide device for a textile machine for placing between a drafting device for supplying a thread and a rotatably driven spindle for winding the thread to a spool, wherein the thread between the drafting and the spindle receives a rotation.
  • the textile machine may be a staple fiber-processing textile machine, in particular a ring spinning machine, wherein it is provided that initially an elongated staple fiber strand, in particular a roving, is presented, which is then drawn by means of a drafting device, wherein the warped staple fiber strand, which in this document "thread" is called, rotated by means of a thread guiding device and wound by means of a spindle.
  • Roving yarns are relatively fine elongated fiber composites of staple fibers, which have a small rotation, namely a so-called protective rotation, which serves to stabilize the fine fiber structure so far that it is spinnable.
  • the fineness of a roving is between 0.9 Nm and 5 Nm, with greater fineness generally increasing, typically between 20 T / m and 75 T / m.
  • Such rovings are spun today practically exclusively with so-called ring spinning machines to a finished twisted thread.
  • a ring spinning machine the spinning process begins in a drafting system with the reduction of the number of fibers per unit length in the roving to the desired fineness of the yarn to be spun, which is typically between 25 Nm and 200 Nm.
  • the rotation is generated by a rotor rotating on a ring.
  • the yarn is wound onto a sleeve plugged onto a rotationally driven spindle as a coil in the form of a cop by the ring / rotor system.
  • the thread runs straight from the spinning zone located directly at the drafting system exit via a thread guide eyelet into a balloon zone.
  • the thread tension prevailing there maintains the dynamic balance with the other forces acting on the runner.
  • Each rotor revolution brings a twist in the yarn, which is introduced into the thread supplied continuously by the drafting system.
  • the final rotation produces the necessary strength in the thread, with the twist in the finish-wound thread usually being between 200 T / m and 2000 T / m.
  • spinning machines suitable for spinning rovings are bell, cap or hopper spinning machines in which a bell-shaped, cap-shaped or funnel-shaped guide element is slipped over the spindle.
  • thread guide is used to deflect the thread to the cop. Upstream of the thread guide is the thread on the inside guided the guide element, so that the problems caused by balloon formation are avoided.
  • the guide element must be driven actively due to its mass, wherein between the guide member and the cop a difference in peripheral speed must be met, which corresponds exactly to the winding.
  • a sufficiently accurate regulation of the speed of the drive of the guide element is hardly possible, especially at higher working speeds, so that disturbances in Kopsprayed and thread breaks arise. Therefore, such spinning machines have not enforced in practice.
  • the object of the present invention is to provide an improved thread guiding device for a textile machine.
  • a thread guiding device of the type mentioned above in that rotor device is provided, which is mounted on a reciprocating in an axial direction relative to the spindle support means by means of a bearing assembly, wherein the bearing assembly comprises at least three support rollers, each are rotatably mounted about a parallel to the axis of the spindle roller axis and which each have a contour at its periphery, which run on an externally formed on the rotor means corresponding counter-contour, so that the rotor device is rotatably mounted coaxially to the spindle, wherein the rotor means a Deflection device for deflecting the thread has, which is arranged so that the thread leaving the deflection device is pulled in the tangential direction to the coil and thereby set d in rotation.
  • a rotor device is understood to mean a rotatable thread-guiding and / or deflecting arrangement.
  • the rotor device can be designed and arranged so that at least one axial portion has an inner diameter such that it can engage over the spindle, a sleeve arranged thereon and a coil formed thereon from the thread.
  • the rotor device is mounted rotatably by means of a bearing arrangement coaxial with the spindle, wherein the bearing arrangement has at least three support rollers which are rotatably mounted about a parallel to the axis of the spindle roller axis and which each have at its periphery a contour which on an outside run on the rotor device formed corresponding mating contour, so that the rotor device is rotatably mounted coaxially with the spindle.
  • the bearings of the support rollers may have a much smaller average diameter, so that the support rollers and ultimately the rotor device can be operated at a much higher speed.
  • the reason for this is that the so-called limit speed of a bearing is approximately inversely proportional to its mean diameter.
  • the mean diameter is the diameter of a circle which runs in the middle between the outer ring and the inner ring of a bearing.
  • the rotor device would have to have an inner diameter of about 50 mm in order to produce a coiled wound coil with a diameter of 40 mm can.
  • this would mean that in the arrangement of the rotor device in the bore of a bearing this would have a mean diameter of about 60 mm would have.
  • the bearings of the support rollers for example, have a mean diameter of 10 mm. If now the support rollers and the rotor device have the same outer diameter, so can the limit speed for the rotor device be increased to six times. If the outer diameter of the support rollers, for reasons of space, only half the outer diameter of the rotor device may have, so the limit speed of the rotor device can still be increased to three times.
  • the bearing arrangement For safe storage of the rotor device are generally sufficient three running on the mating contour support rollers. Nevertheless, the stability of the bearing arrangement can be increased by a larger number of support rollers. As a rule, it is also sufficient if the bearing arrangement has exactly one counter contour and the support rollers running on it with its respective contour. However, it can also be provided that the bearing arrangement has a plurality of mating contours, on each of which run at least three support rollers.
  • the rotor device may in the simplest case of a ring on which the counter contour is formed, and a Umlenkeicardi, for example, an eyelet or a hook made of wire, exist.
  • the thread guide device according to the invention can have a significantly lower rotating mass than a thread guide device with a rotor device arranged in a bore of a bearing or as a thread guide device with a bell-shaped, cap-shaped or funnel-shaped guide element.

  • the drive of the rotor device Therefore, it can only be done via the thread pulled by the spindle. This creates a self-regulating drive of the rotor device, which compensates for changes in the spindle speed and / or the Aufwinde shedrs automatically. In this way yarn breaks and disturbances are avoided by the coil structure due to drive-related fluctuations in the yarn tension.
  • the thread guide device according to the invention can replace the conventional ring / traveler system, so that its wear problems and / or speed-limiting effects are avoided.
  • the circular path of the deflection device may have a larger radius than the circular path of the rotor of a ring spinning machine, which is limited at a given speed by the maximum speed of the rotor.
  • coil or cops can be produced with a larger diameter.
  • the thread guiding device is particularly suitable for spinning machines, which spin rovings with a fineness between 0.9 Nm and 5 Nm and a rotation between 20 T / m and 75 T / m and finished finished threads with a fineness between 25 Nm and 200 Nm and a Generate rotation between 200 T / m and 2000 T / m.

  • the support rollers are arranged distributed uniformly in the circumferential direction. This is understood to mean that the angles between the straight lines running through the roller axes and the axis of the spindle are the same. Thus, for example, if three support rollers are provided, then the angle between these straight lines is 120 ° in each case. In this way, a particularly stable mounting of the rotor device, which allows smooth running of the rotor device even at higher speeds results.
  • the contours of the support rollers and the mating contour on the rotor device cooperate so that the rotor device is mounted axially and radially.
  • the support rollers can take over both an axial and a radial guidance of the rotor device, so that further bearing elements are dispensable.
