Definitions
- the invention relates to a arranged between Strec plant output and ring spindle thread guide device for ring spinning machines, which has a swirl element which is arranged at a distance above the upper end of the ring spindle and is coupled to the ring spindle via a magnetic force field, so that the swirl element with the same speed how the ring spindle rotates.
- This rotating thread guide consists of a ball-bearing swirl element, which is expediently made of ceramic, which is mounted above the upper spindle part of the ring spindle independently of it on the machine frame, and magnetically coupled to the ring spindle via permanent magnets arranged in the spindle head and in the swirl element and upon rotation the same is taken away.
- the spindle speed is transmitted synchronously to the swirl element through this magnetic coupling.
- This known device (Textilpraxis International 1982, January, pages 19 and 20) gives the thread in the spinning zone an incorrect rotation by touching the thread as it passes through the swirl element and the edge of the spindle upper part.
- a rotating thread guide is known, which is arranged as a twist device between the usual thread guide above the spindle and the ring traveler directly above the ring spindle, a rotating body being carried by the spindle by means of a magnetic coupling.
- the fiber structure is introduced centrally and laterally out of the rotating body, from where the fiber structure extends in a balloon to the ring traveler.
- the rotating body should have a helical channel and be driven slower or faster than the spindle regardless of the spindle. This is intended to temporarily overlay a small false wire on the fiber structure.
- This known device has also not been able to be introduced in practice, since the external drive is too complex and, moreover, there is no defined rotation.
- the object of the invention is to avoid these disadvantages of the prior art and to provide a device which is able to ensure better and defined propagation of rotation up to the spinning triangle.
- the device should be simple and easy to use at the same time.
- a defined entrainment of the thread by the swirl element takes place, so that the thread is given defined rotation in the critical area between the thread guide device and the drafting device.
- the upswing is continuous and effects bumpless.
- the inevitable entrainment of the thread eliminates slippage and unpredictability as in the case of entrainment of friction and thus also the influences of the entry angle into the thread guiding device.
- the wrapping around the core of the swirl element acts like a brake, so that voltage peaks starting from the rotor and the balloon are damped and cannot have an effect in the sensitive area between the thread guide device and the drafting system.
- the thread bale is reduced so that balloon constriction rings are not necessary.
- the rotation imparted by the spindle is increasingly generated between the thread guide device and the drafting system outlet.
- the rotation propagates until just before the drafting system exit and leads to a rapid solidification of the fiber sliver emerging.
- the driver is expediently designed as a helix, since the helix prescribes a defined wrap around the thread. Operator errors are prevented.
- the braking effect can be reduced or increased.
- the helix angle ⁇ of the helical coil is expediently between 360 ° and 720 °, preferably approximately 540 °, in order to achieve optimal damping.
- the upper and lower ends of the helical coil 13 are designed as an edge which lies in a plane perpendicular to the axis of rotation of the helical coil and is appropriately rounded.
- the encapsulation of the twist element not only protects the twist element and the thread path, but also prevents winding or knotting of the thread if the thread breaks.
- this encapsulation enables automatic threading using suction air, which leads to savings in operating times when removing threads.
- it can be be ßig to provide the encapsulation of the swirl element with ventilation openings.
- the eccentric arrangement of the thread inlet bore has surprisingly meant that there is no balloon formation between the thread guide device and the drafting system.
- the eccentricity suitably depends on the radius of the core of the driver.
- the central arrangement of the thread outlet bore ensures vibration-free twist distribution.
- the pivotability of the thread guide device from an operating position to an operating position not only enables the manual or mechanical removal of the cops without problems, but also serves to maintain and keep the thread guide device clean.
- the thread guide device can expediently be coupled to a suction device, which can simultaneously actuate the thread guide device by moving it into the operating position. In this way, the thread guiding device is cleaned of flight and threaded through the suction device of the thread for re-spinning into the thread guiding device.
- Figure 1 shows the thread guide arrangement according to the invention in connection with the ring spindle and a suction device;
- Figure 2 shows the driver designed as a helix according to Figure 1;
- Figure 3 is a plan view of the driver according to Figure 2;
- FIG. 4 shows a plan view of the housing according to FIG. 1;
- Figure 5 shows another embodiment of the thread guide device according to the invention.
- Figure 6 shows the spinning station of a ring spinning machine with a further embodiment of the thread guide device.
- Figure 7 shows an embodiment of the housing of the thread guide device with ventilation openings in section.
- FIG. 1 an embodiment of a rotating thread guide device is shown in section. It consists of a housing 2 with an eccentrically arranged yarn inlet opening 21, the swirl element 11 rotatably mounted in a ball bearing 16 with a centrally arranged thread outlet opening 22.
- a driver 13 is mounted and connected to it in a rotationally fixed manner, so that this driver 13 rotates together with the swirl element 11.
- the driver 13 has a core 13 'which extends coaxially to the axis of rotation and around which a thread F which extends from the spindle 3 to the drafting system outlet can be looped.
- the swirl element 11 with the driver 13 is expediently encapsulated by a housing 2 to protect the thread running through the swirl element 11 and to avoid winding or knots in the event of thread breakage: the housing 2 is placed stationary on the bearing ring 17, which serves to receive the ball bearing 16. The bearing ring 17 is received by a holder 18 which is pivotable about a hinge 19. As a result, the thread guiding device 1 can be pivoted up into the operating position 1 'shown in dashed lines, so that the head of the spindle 3 is free and accessible for the removal of the cops and reinserting sleeves 4.
- a further suction device 5 in the form of a tubular profile is arranged on the ring spinning machine parallel to the usual sliver suction arranged under the drafting rollers.
- Each spinning station is assigned a suction opening 51 on this tube 5, against which the thread inlet opening 21 of the thread guiding device 1 bears in the operating position 1 ', so that suction air 5 is sucked through the thread guiding device 1 by the suction device 5.
- This suction serves on the one hand to keep the thread guiding device 1 clean of flight and similar loose deposits.
- the thread F carried up by the spindle 3 can be placed in front of the central thread outlet opening 22 so that it is sucked into the thread guiding device 1 and thus threaded.
- the thread guide device 1 For re-spinning, the thread guide device 1 is folded down from its operating position 1 'into the operating position.
- the thread F extending from the thread inlet opening 21 into the suction opening 51 is taken up for the start of the spinning process and is applied to the drafting device in a known manner.
- the suction opening 51 is expediently visible and closable by the movement of the thread guide device 1 in order to avoid unnecessary air consumption in the operating position. This can be done in a simple manner in that a cam is arranged on the thread inlet opening 21 of the thread guide device 1, which presses on the closure of the suction opening 51 or actuates it in another way, so that the suction device 5 is activated when the thread guide device is in the operating position 1 " to the Mamming opening 51 creates, and the suction opening 51 is closed again when the thread guide device 1 is pivoted back into its operating position.
- the part of the swirl element 11 facing the spindle 3 is designed as a magnet and forms a magnetic coupling with the head 31 of the spindle 3, which is also equipped with permanent magnets, so that the swirl element 11 rotates at the same speed as the spindle 3.
- the distance of the spindle head 31 from the swirl element 11 is determined in a known manner by the magnetic field which is necessary to ensure that the swirl element 11 is carried along by the spindle 3. As a rule, this distance is about 5 to 10 mm.
- the driver 12 is designed as a cross or T and consists of the core 12 'around which the thread F passing through the thread guide device 100 is looped and an edge 14 which acts as a crossbar Core 12 'is attached.
- This edge 14 takes the thread F entering through the thread inlet opening 24 and gives it rotation analogous to the spindle speed.
- the thread leaves the thread guide device 100 via a thread outlet opening 23 in the twist element 10.
- the twist element 10 is rotatably mounted in a ball bearing 16 in the bearing ring 17 on the holder 18.
- the drive is carried out by the magnetic coupling described above between the spindle head 31 and the swirl element 10.
- the thread is looped around the core 12 ′ of the driver 12.
- the looping takes place once or twice in order to obtain the desired damping.
- such a wrap requires an increased amount of time for manual threading through the loading. service required.
- the housing 20 must also be removable for this purpose.
- only whole or half loops are possible. A finer gradation would be provided if a further crossbeam was provided as the lower driver edge, for example offset by 90 ° to the edge 14.
- the driver 13 is therefore designed as a helix, as shown in detail in FIG.
- the screw helix 13 has an edge 15 at its upper end and an edge 15 'at its lower end, via which the thread F runs into the screw helix 13 or out of the screw helix.
- the winding angle ⁇ of the helical coil 13 is precisely defined by the two edges 15 and 15 'and the wrap around the core 13' is automatically determined. As described above, the thread is sucked in, automatically engages in the course of the helical coil 13, and the desired wrap is produced.
- the edges 15 and 15 ' are preferably designed as a rounded web.
- the damping acts in the following way:
- the friction of the thread as a result of the wrap on the driver 12 or 13 makes it stronger Train from the thread balloon required, which has the consequence that the balloon is smaller. This eliminates the need for balloon constriction rings and their movement control. At most, they are still necessary for the winding of the cop attachment.
- the tension in the spinning zone between the thread guide device and the drafting system is significantly reduced, since this is retained by the friction on the driver 12 or 13. In particular, tension peaks, which are formed by runners and balloons and which have often led to thread breaks, are eliminated from the spinning zone.
- the functioning of the thread guide device is as follows: The from the
- the edges 15 and 15 'or the driver 12 with the edge 14 which surround the driver 13 capture the thread F which extends through the housing 2 or 20 and impart this to the driver by rotating the spindle speed, since the spindle 3 has the swirl element via the magnetic coupling 10 or 11 drives.
- the thread F leaving the twist element 10 or 11 runs over the thread balloon in usually under the rotor 63 rotating on the spinning ring 62 for winding onto the sleeve 4. Since the rotor 63 remains behind the angular velocity of the spindle 3 by the winding, it rotates this amount again reduces the real twist which the thread F 'has received in the spinning zone.
- the thread guide device according to the invention achieves 109% of the rotation in the critical area between the drafting device outlet and the thread guide device in the thread F 'at a wrap angle of 360 ° in front of the spinning triangle, and even 115% turn at a wrap angle of 720 ° to the target twist in the finished yarn.
- only 84% of the target rotation in front of the spinning triangle could be achieved with the conventional thread guide with balloon constriction ring. This means that the spinning triangle is reduced and the emerging fiber structure is immediately solidified in this critical area. Therefore, thread breaks hardly occur in this area.
- the difference between the angular velocity of the spindle 3 and the angular velocity of the rotor 63 is compensated for after the thread F has left the twist element 11 or 10 in the direction of the rotor / spinning ring.
- the thread F can move freely in the space between the spindle head 31 and the swirl element 10 or 11, so that this compensation takes place continuously, in contrast to the measures for propagating rotation known from the prior art.
- the thread F should be able to move as freely as possible, although it may touch the spindle head 31, but should not rub against it in such a way that a torque is exerted on the thread, in particular not in the untwisting direction.
- the magnetic coupling of the thread guiding device 1 or 100 causes the spindle head 31 at a short distance of about 5 to 10 millimeters in order to guarantee the entrainment of the swirl element 10 or 11. It is therefore necessary to extend the spindle beyond the end of the sleeve 4, for example by at least 25 mm.
- a central thread inlet bore 24 is shown, while in the embodiment in FIG. 1 the thread inlet bore 21 is arranged eccentrically.
- the eccentric thread inlet bore 21 is more advantageous than a central thread inlet bore 24 since it avoids ballooning between the thread guide device 1 or 100 and the drafting device outlet.
- the eccentricity e of this thread inlet bore 21 to the axis of rotation of the driver 13 should correspond approximately to the radius of the core 13 'of the helical coil 13 (FIG. 4).
- the thread inlet bore 24 would have to be arranged eccentrically to the axis of rotation of the driver 12 around the radius of the core 12.
- a central thread outlet opening as shown in FIG. 1, is more advantageous than an eccentric one 5, since vibrations and thus tension peaks due to vibrations are avoided by the central guidance of the thread balloon.
- the thread F wrapped around the core 13 ' is removed from the lower edge 15' of the screw spiral 13 in a free space 25 of the swirl element 11 is guided under the driver 13, through which the thread F enters the central thread outlet bore 22.
- FIG. 6 the entire spinning station including the spindle 3 with its bearing 32, as well as the ring bench 6 and the spinning ring 62 is shown schematically.
- balloon constriction rings 61 are rigidly attached to ring bank 6. Since, as a result of the thread guide device according to the invention, balloon constriction rings 61 are required at most when winding the cop attachment, a separate movement control can be dispensed with. When winding onto the tip of the head, however, the balloon constriction ring 61 would be prevented from moving by the holding of the thread guiding device 1 or 100.
- a cranked holder 181 is therefore provided for the thread guiding device 1 or 100, which extends through the balloon constriction ring 61 so that the distance for the magnetic coupling of the twist element 10 or 11 is made possible.
- the balloon constriction ring 61 with the ring bench 6 can assume the upper position necessary for the winding, which is indicated by dashed lines in FIG. 6.
- FIG. 7 shows a further embodiment of a housing 200 of the thread guiding device 1 or 100.
- ventilation openings 26 are provided.
- the thread guide device according to the invention has been described with reference to two embodiments.
- the invention is not limited to the embodiments described, for example the driver 12 or 13.
- Other designs of the driver for example also as an eyelet or in a similar manner, realize the inventive idea and the function achieved in the same way.
- the invention is also not limited to the application described in conventional ring spinning.
- the invention can also be used with considerable advantage in the so-called “Siro spinning", in which two warped fiber lunches which run out of the drafting device are spun into a twisted thread.
- Siro spinning in which two warped fiber lunches which run out of the drafting device are spun into a twisted thread.
- the triangle between the two converging fibers at the exit of the drafting system could be shortened by half.
