Definitions
- the invention relates to a cylindrical cheese and a Method of forming the winding body of a cylindrical Cross-wound bobbin with a thread guide according to the preamble of Claims 1 and 7.
- 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 "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.
- 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 cylindrical cross-wound bobbins improved cylindrical Cross-wound bobbin and a method for its manufacture Rotor spinning machines, especially when producing coarse ones Yarn to create.
- the object is achieved by a method according to claim 1 and cylindrical cheese according to claim 7 fulfilled.
- 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 cylindrical cheese.
- the thread flow is calmer, counteracts loop formation and yarn entanglement and thus allows higher thread take-off speeds.
- the Coil structure, especially on the end faces of the cylindrical cheese, is improved.
- the barrel length of the Yarns with the same bobbin diameter show up opposite a common cylindrical cheese of the same winding type clearly increased.
- the formation of the crossing angle ⁇ leads to an increase in the wound thread length, with excellent stability of the cylindrical bobbin can be maintained 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 spool contact pressure is known to consist of the Weight of the coil and the weight of the coil frame together as well as from the force that comes from, for example, one 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 cylindrical cheese according to the invention without additional construction effort and without changing Thread guide elements through the appropriate device or programming the controller on simple Run 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 cylindrical cheese has increased by approx. 15% to 25% Amount of yarn compared to a conventional cylindrical cheese same coil diameter is wound. this leads to a significant reduction in the number of packages one Partie. This not only reduces downtimes for changing bobbins at the spinning positions, but also the Transport effort and the transport volume during coil transport are reduced. The effort for handling the Cross-wound bobbins in subsequent yarn processing processes be lowered.
- 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 cylindrical Spinning unit producing a bobbin Rotor spinning machine.
- the winding device 1 has a roller 2 which, by means of friction, the cylindrical cheese 3 drives.
- the roller 2 rotates in the direction of arrow 4.
- Die Cross-wound bobbin 3 is pivoted through a bobbin frame 5 supported and lies on the roller 2.
- the roller 2 will applied with a contact pressure.
- the thread 6 is in Direction of arrow 7 by means of a pair of rollers cooperating take-off rollers 8, 9 from the spin box 10 of the Spinning station with constant thread speed and via a reciprocating thread guide 11 as cylindrical winding body 12 of the package 3 wound.
- the thread guide 11 is part of a traversing device 13 which connected via an operative connection 14 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 cylindrical cheese 3, depending from the position of the thread guide 11, during the respective Coil stroke is controllable.
- the cylindrical cross-wound bobbin 3 shown in FIG. 2 shows a winding body 12 wound according to the invention on the bobbin tube 19.
- the winding body 12 has a cross winding with the crossing angle ⁇ R in the edge zones 20, 21 and a cross winding with the crossing angle ⁇ M in the central zone 22 on.
- ⁇ R is 35 °
- ⁇ M is 25 °.
- the width of the zone 22 and the edge zones 20, 21 is marked by a dashed line.
- the cylindrical winding body 12 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 3 from the left bobbin edge 23 to the right bobbin edge 24 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 package 3 or the course of the thread on the lateral surfaces closer than the illustration in FIG. 2.
- FIG. 3 shows the as Curve 31 over the winding width B WG of the cross-wound bobbin 3 shows the course of the size of the crossing angle ⁇ , the values representing the stroke of the thread guide 11 in the representation of the cylindrical bobbin 3 of FIG. 2 from left to right (Stroke of the thread guide 11 during the forward movement) represent.
- 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 in more detail here by controlling the rotational speed of the cheese 3 and the speed of the traversing movement of the thread guide 11 during the stroke.
- the cylindrical cross-wound bobbin 3, which is designed with a crossing angle ⁇ of ⁇ R 35 ° in the edge zones 20, 21, has stable bobbin edges 23, 24, without impermissibly high pressing pressure being exerted. This prevents bulges on the end faces of the cheese 3.
- the running behavior of the cylindrical cheese 3 is improved by calmer thread running and the suppression of Loop formation and yarn entanglement.
- the thread guide can alternatively for example as a belt thread guide or as Grooved roll to be formed.
- the crossing angle ⁇ of the cylindrical cheese according to the invention can advantageously in a range of 30 ° to 40 ° in the peripheral zones 20, 21 and in the middle zone 22 in a range of 15 ° to 28 ° accept alternative values.
