Definitions
- the invention relates to a method for spinning staple fibers, in particular short staple fibers on ring spinning machines, wherein a staple fiber warping in a drafting and twisted together on exit from the drafting to a thread and wound up by means of a ring / rotor device, wherein the emerging from the drafting fiber structure then passes through a thread guide, which has a equipped with a braking device twisting device, which drives synchronously driven with the spindle speed the fiber strand rotation, and an apparatus for performing the method.
- crowns to put on the ring spindle to make the outgoing from the circulating on the ring rotor spin direction towards the spinning triangle out more effective and in the critical area to achieve a better solidification of emerging from the drafting fuse (DE 1 116 584).
- the thread lies in the teeth of the crown and is taken through them, but the yarn on the Krone make the same backward movement as the rotor on the spinning ring, which remains behind the peripheral speed of the spindle according to the winding and the winding speed.
- the thread is held back in the crown of the crown until the tension is so great that the thread jumps into the next point.
- a rotating yarn guide is known, which is arranged as a swirl device between the usual yarn guide on the spindle and the ring rotor directly above the ring spindle, wherein a rotary body is entrained by means of a magnetic coupling of the spindle.
- the fiber structure is introduced centrally and led out laterally from the rotary body, from where the fiber structure extends in a balloon to the ring traveler.
- the rotary body should have a helical channel and be driven independently of the spindle slower or faster than the spindle. This should be the fiber structure temporarily superimposed a small false twisted wire.
- a thread guide device with a swirl element at a distance above the upper end of the ring spindle and to couple this swirl element to the ring spindle via a magnetic force field.
- the swirl element has a thread brake device, which consists of a coaxially extending to the axis of rotation core around which the yarn guide passing yarn is herumschlingbar and a arranged on the core driving edge.
- the spinning speeds could be increased considerably.
- the balloon diameter is reduced so that balloon constriction rings are largely unnecessary, now allow higher spin speeds an increased energy demand.
- Object of the present invention is to reduce energy consumption in a thread guide device of this known type and thus to enable the higher production rates and economic. This object is solved by the features of claims 1 and 6.
- the braking of the thread in the twisting device prevents impacts coming from the grooves of the spindle attachment from propagating into the twisting zone.
- This braking device makes it possible to keep the total thread tension low, and to let the rotation produced by the swirl element fully effective up to the spinning triangle.
- the thread friction generated by the attachment is negligible, so that an excellent thread quality is produced despite very high spindle speeds.
- the swirl element nachge- switched attachment is the twist distribution and the balloon suppression separated.
- Each of the two elements can be designed and optimized according to its task. Surprisingly, it has been shown that considerable energy savings can be achieved by the downstream connection of a spindle attachment according to the swirl element, without impairing the yarn quality achieved by the swirl element of the thread guiding device, so that only through this combination can the advantages of this thread guiding device with swirl element be fully exploited, namely high productivity and quality with simultaneous energy savings.
- the attachment For entrainment of the swirl element by the spindle, the attachment has a spaced-apart from the swirl element end face containing a permanent magnet which forms a magnetic force field for entrainment of the swirl element with a gegenpoligen magnet on the swirl element.
- the article itself expediently has a cylindrical lateral surface, in which extending into the end face of the essay extending grooves are provided so that they can easily detect the emerging from the swirl element thread.
- the diameter of the attachment resembles the spindle diameter adjoining the attachment, so that the thread entrained by the attachment winds easily and inevitably around the spindle and thus no balloon is formed.
- the diameter of the attachment may extend beyond the subsequent spindle diameter by the groove depth. But it is also useful and gentle for the thread when the grooves expire with their groove bottom on the adjoining spindle diameter. Due to the separation of twist distribution and balloon suppression, there is the advantage that only the gentle entrainment of the thread is to be considered in the design of the spindle attachment.
- the grooves Due to the exact predetermined geometry of the yarn path, it is not necessary that the grooves extend over the full length of the lateral surface of the essay. It has proven to be advantageous and expedient to equip the article at its end facing the yarn guide element 1 end with a shank which projects beyond the shank diameter of the attachment 33 and which is provided with grooves.
- the grooves are adapted in their orientation and length of the geometry of the yarn path. It is sufficient for a good entrainment that the grooves cut through the edge of the rim formed by the end face and the lateral surface at an angle ⁇ .
- the number of grooves should be as large as possible. It has proven to be useful to adjust the width of the grooves about twice the yarn diameter.
- the depth of the grooves is suitably about half a groove width. As a result, a slight catching of the thread, but also a good release of the thread is ensured in the next groove, without excessive voltages and surges occur. The quality of the thread is not affected in this way.
- Figure 1 shows the swirl element with the downstream spindle attachment.
- Figure 2 shows an overall arrangement of the spindle with spindle attachment and swirl element.
- FIG. 5 Comparison of the power consumption with and without spindle attachment;
- Fig. 6 shows another embodiment of the spindle attachment.
- the thread guiding device consists of a thread guiding device 1 arranged above the spindle, which has a swirl element 10 which contains a combustion device.
- This braking device consists of a driver 13, which has a coaxially to the axis of rotation extending core 13 ', around which one of the spindle 3 to the drafting equipment outlet extending thread F is herumschlingbar, which is still unfinished in its upper part F'.
- an upper edge 15 and a lower edge 15' is provided, on which the thread guide 1 continuous thread F is applied and taken on rotation of the swirl element 10.
- the spindle 3 facing part of the swirl element 10 is formed as a magnet and forms with the attachment 33 of the spindle 3, which is also equipped with permanent magnets 31, a magnetic coupling, so that the swirl element 10 rotates at the same speed as the spindle 3.
- the distance of the spindle attachment 33 from the swirl element 10 is determined in a known manner by the magnetic field, which is necessary to ensure entrainment of the swirl element 10 by the spindle 3. As a rule, this distance is about 5 to 10 mm.
- the thread guide device 1 with the swirl element 10 is an attached to the spindle 3 essay 33 downstream.
- This attachment 33 expediently has a cylindrical shell shape, in which grooves 32 are provided, which extend into the end face 34 of the attachment 33.
- the grooves can be designed differently. It is important that the thread F is protected in its entrainment by the grooves.
- the diameter of the attachment 33 can project beyond the subsequent spindle diameter around the groove depth (FIGS. 3 and 4). However, it is also expedient and gentle for the thread F, if the grooves 33 with their groove bottom to the subsequent spindle diameter (Fig. 1 and 2) or attachment diameter (Fig. 4) expire.
- the thread guiding device 1 is arranged over the end face 34 of the attachment 33 in such a way that the thread F exiting from the twist element 10 emerges centrically with respect to the end face 34.
- an exact geometry of the thread F is independent of the rotation of the spindle 3 given the transition into the grooves 32 of the attachment 33.
- the thread F is detected easily and safely and taken so long until the tension in the thread F is so great that it jumps out of the groove 32 in the next adjacent groove 32 by the remaining rotor 63.
- the tension in the thread F is increased so that no balloon is formed, but the thread F spirally wraps around the attachment 33 and the spindle 3.
- the grooves 32 need not even be very pronounced and sharp-edged to catch the thread F and hold it. This protects the thread and prevents roughening. It has proven expedient to dimension the depth of the grooves 32 to be approximately half the width of the grooves 32. This makes it possible to lift the thread F out of this groove 32 with only a slight pull. The surges are low and the friction on the thread F also, so that the quality of the thread is not affected. To avoid large jumps, it is expedient to arrange as many grooves 32 on the circumference of the attachment 33. Thus, the differences in length and the jumps of the thread F are small.
- FIG. 6 shows another embodiment in which the spindle attachment 33 has, at its end facing the yarn guide element 1, a collar 36 projecting beyond the shank diameter of the attachment 33 and provided with grooves 35.
- These grooves are in their orientation and length of geometry adapted to the yarn path. They run inclined to the axis of rotation of the attachment 33 and cut through the edge of the rim 36 formed by the end face 34 and the lateral surface at an angle ⁇ . This angle ⁇ is determined by the central exit from the yarn guide element 1 and the yarn path, under which the yarn F reaches the edge 35 of the rim 36 provided with the grooves 35.
- These grooves 35 are rectangular in cross-section, but in their longitudinal section they form a triangle.
- the twisting device 10 is further provided with a braking device.
- This braking device surges are attenuated and compensated, so that this on the Spinning line between drafting system exit and swirl element can not affect.
- the given rotation propagates unhindered and completely to the drafting system exit.
- the swirl element 10 is immediately followed by the attachment 33 provided with grooves 32, 35. The balloon suppression is independent of the rotation process.
- the swirl element 10 is aligned exclusively to the swirling, while the spindle attachment 33 detects a finished twisted thread F, which is largely insensitive to the entrainment by the grooves 32, 35 detecting it.
- the spindle attachment 33 and the grooves 32, 35 are designed exclusively for balloon suppression, wherein the braking device provided in the swirl device almost completely compensates for the shocks resulting from jumping from one groove 32, 35 into the other.
- the rotation process takes place continuously without disturbances and takes place exclusively in the area between the drafting system exit and the swirl element.
- the deceleration of the thread F in the twisting device 10 plays a decisive role here.
- the thread tension can be regulated and kept low overall.
- the frictional stress of the thread F through the grooves 32, 35 of the spindle attachment 33 is therefore small.
- the thread quality is not affected.
- the wrap angle By changing the wrap angle, the braking effect can be regulated.
- a half or a wrap has proven to be optimal for the braking of the thread F with simultaneous balloon suppression. Further details are described in the earlier application of the same inventor (WO 2004/072339 A1).
- the thread is therefore already largely insensitive, because the swirl element 10 leaves a finished twisted thread F.
- Investigations have shown that, compared to a conventional yarn guide, with which only about 93% of the rotation of the finished yarn is achieved, with the swirl element 10 more than 100% rotation in the rich of the spinning triangle can be achieved. If the spindle attachment 33 is used without swirl element 10, the friction on the shaft of the spindle 3 and the spindle attachment 33 results in a rotation jam, wherein even only 85% of the rotation is present in the region of the spinning triangle. This has in the past led to unacceptable quality losses in the thread, especially when spinning short staple fibers, as well as frequent thread breaks.
- swirl element with thread brake without balloon constriction ring a) swirl element with thread brake without balloon constriction ring; b) the swirl element with thread brake and downstream spindle attachment (suppressed thread balloon).
