Definitions

  • the invention relates to a conical cheese and a Process for forming the winding body of a conical Cross-wound bobbin with a thread guide according to the preamble of Claims 1 and 6.
  • Yarn made on rotor spinning machines differs compared to the ring spun yarn in the bobbin and in Flow behavior.
  • the rotor yarn is less hairy than that Ring spun yarn and can thus be more easily unwound (easier lifting), but has a greater tendency to curl than the ring spun yarn, so that the wound yarn in Edge area of the package from the overlying ones Yarn layers is pushed outwards.
  • This can result in a over the normal spool stroke of 150 mm, for example beyond, up to a width of 170 to 180 mm form fully-grown cheese. In such a case comes a desired coil structure with flat end faces is not more come about.
  • Such phenomena occur with yarns natural fibers such as cotton, especially for coarse ones Yarn on and are more pronounced, the coarser the yarn is.
  • the crossing angle limits the maximum allowed Diameter in the manufacture of precision coils Staple fiber yarns, especially for staple fiber yarns Avoidance of the defects occurring at the edges arbitrarily small crossing angles can be wound. Out for this reason, such as in the DE 100 15 933 A1 described in rotor spinning Crossing angles of less than 28 ° can be avoided. Thereby is precision winding, especially when winding Staple fiber yarns, of limited use.
  • the "step precision winding” becomes an approximation of the coil journey constant crossing angle aimed. Even with the Step precision winding are the ones described above Density problems or problems with the stability of the In practice, the coil edge is only slightly reduced, however not resolved.
  • the generic DE-AS 26 32 014 shows a conical Cross-wound bobbin by circumferential friction from a roller is driven.
  • This drive roller has one in the middle with a small friction zone protruding from its surface increased coefficient of friction.
  • the drive should only be in the predetermined Area of the friction zone or the friction zone of the Cheese. Nevertheless, the package can be wound with increasing coil diameter contact with the left and parts to the right of the predetermined friction zone the roller-shaped drive device. This will the spool no longer in the friction zone alone, but also driven in other places of the circumference.
  • conical Coils seen the coil circumferential length over the coil axis is different, the speed of the cheese fluctuating and uncontrollable.
  • New machine technologies especially in weaving, such as Air jet weaving machines, for example, place increased demands with regard to the running properties of the yarn.
  • the Requirements can be met with the known coil designs not or only insufficiently.
  • the invention is based on the object known conical packages improved conical Cross-wound bobbin and a method for its manufacture Rotor spinning machines, especially when producing coarse ones Yarn to create.
  • the invention is based on the knowledge that in opposite the crossing angle in the central part larger crossing angles in Edge area of the package the crossing angle in remaining wider middle section clearly compared to usual Crossing angles can be reduced without the one Reduction of the crossing angle over the entire Wrapping width known disadvantages in purchase to have to take. Lowering the crossing angle can thereby being pushed far without becoming one impermissible hardening of the cheese.
  • the invention leads to an improved flow of the thread from the package.
  • the thread flow is calmer, works Loops and yarn entanglement counter and allowed thus higher thread take-off speeds.
  • the coil structure, especially on the end faces of the cheese improved.
  • the length of the yarn at the same Coil diameter shows up compared to a conventional coil same winding type significantly increased.
  • the formation of the crossing angle ⁇ according to one of claims 2 and 3 and 7 and 8 leads to an increase in the wound thread length, with excellent stability of the conical winding body can be achieved at high density.
  • the crossing angle ⁇ advantageously increases continuously from the crossing angle ⁇ M of the central zone to the crossing angle ⁇ R of the peripheral zone.
  • the edge zones can be dimensioned such that they do not occupy more than 15% of the total winding width B WG .
  • the bobbin contact pressure is made up of weight the spool and the weight of the spool frame together as well the force resulting from that of, for example, a Torque sensor applied torque results.
  • the Spool contact pressure can be reduced so that not only the coil weight is compensated, but one above additional discharge occurs.
  • Thread guide for example a belt thread guide, for production the traversing movement, the speed of which is separate is controllable from the spool speed, that can be Process according to the invention for producing a cheese according to the invention without additional structural Effort and without changing thread guide elements the corresponding setup or programming the control in a simple way.
  • the invention also allows coarse yarns with relative at low crossing angles. For example, that is Processing of cotton yarn with Nm 20 at one Crossing angle ⁇ of 25 ° with the associated good Drainage properties and long barrel lengths are still possible. Improved drainage properties lead to a reduction in Downtimes by reducing the number of thread breaks the further processing of the bobbins. With the through the Reduction of the crossing angle increasing barrel length can be achieved that on an inventive conical bobbin an amount of yarn increased by approx. 15% to 25% compared to a conventional coil with the same coil diameter is wound up. This leads to a significant reduction the number of bobbins in a lot. This will decrease not only downtimes for changing bobbins on the Spinning and winding units, but also the transport effort and the transport volume during coil transport is reduced. The effort for handling the coils in subsequent Yarn processing processes can be reduced.
  • the invention improves productivity and enables Reduce costs and overall profitability of yarn production and processing.
  • Figure 1 shows a winding device 1 on a conical Spinning unit producing a bobbin Rotor spinning machine.
  • the winding device 1 has a roller 2 on, which drives the conical cheese 3 by means of friction.
  • the roller 2 rotates in the direction of the arrow 4.
  • the cheese 3 is held by a swiveling coil frame 5 and lies on roller 2.
  • the roller 2 is with a Contact pressure applied.
  • the thread 6 is in the direction of Arrow 7 by means of interacting as a pair of rollers Take-off rollers 8, 9 from the spinning box 10 of the spinning station subtracted constant thread speed and over a Thread 6 reciprocating thread guide 11 as Winding body 12 of the cheese 3 wound.
  • the Thread guide 11 is part of a traversing device 13 which an operative connection 14 connected to the motor 15 and from this is driven.
  • the roller 2 is on the shaft 16 of driven by a motor 17. Both the motor 15 and the Motor 17 are controlled by a microprocessor 18, wherein the crossing angle ⁇ of the conical cheese 3, depending on the position of the thread guide 11, during the respective Coil stroke is controllable.
  • the conical cross-wound bobbin 25 shown in FIG. 2 shows a winding body 27 wound on the bobbin tube 26 according to the invention.
  • the winding former 27 has a cross winding with the crossing angle ⁇ R in the edge zones 28, 29 and a cross winding with the crossing angle ⁇ in the central zone 30 M on.
  • ⁇ R is 35 °
  • ⁇ M is 25 °.
  • the width of the zone 30 and the edge zones 28, 29 is each marked by a dashed line.
  • the winding body 27 is shown in a simplified schematic diagram, the respective course of the thread 6 being laid out being only partially indicated, but showing differently large crossing angles ⁇ .
  • the width B WG of the cheese 25 from the left bobbin edge 33 to the right bobbin edge 34 is 150 mm in the exemplary embodiment.
  • the width B WG corresponds to a stroke of the thread guide 11.
  • FIG. 3 is the actual one Formation of the crossing angle ⁇ of the cheese 25 or the thread course on the lateral surfaces closer as the representation of Figure 2.
  • FIG. 3 shows the course of the size of the crossing angle ⁇ shown as curve 31 over the winding width B WG of the conical cross-wound bobbin 25, the values representing the stroke of the thread guide 11 in the representation of the cross-wound bobbin 25 from FIG. 2 from left to right (stroke of the thread guide 11 during the forward movement).
  • the width of the central zone 30, in which the crossing angle ⁇ lies at the value of ⁇ M 25 °, takes up more than 60% of the winding width B WG .
  • the course of the size of the crossing angle ⁇ during the stroke of the thread guide 11 in the return movement to the left is indicated by dashed lines in FIG. 3.
  • the setting of the crossing angle ⁇ is carried out in a manner known per se and therefore not explained here in more detail by controlling the rotational speed of the cheese 3, 25 and the speed of the traversing movement of the thread guide 11 during the stroke.
  • the advantageously low crossing angle ⁇ of ⁇ M 25 ° in the zone 30 lying between the edge zones 28, 29 enables a longer run length with a stable winding body with the same finished diameter of, for example, 300 mm of the package 25, which thereby 15% to 25% more yarn contains as usual coils of the same diameter.
  • the running behavior of the cheese 3, 25 is improved by quieter thread running and the suppression of loop formation and yarn entanglements.
  • the thread guide can alternatively for example as a belt thread guide or as Grooved roll to be formed.
  • the crossing angle ⁇ can advantageous in a range from 30 ° to 40 ° in the Edge zones 28, 29 and in the central zone 30 in one area from 15 ° to 28 ° accept alternative values.
