Definitions

  • the invention relates to a arranged between drafting equipment 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 via a magnetic force field with the ring spindle, so that the swirl element at the same speed as the ring spindle turns.
  • This rotating thread guide consists of a ball-bearing swirl element, which is suitably made of ceramic, which is mounted on the spindle upper part of the ring spindle regardless of this on the machine frame, and coupled in the spindle head and in the swirl element permanent magnets magnetically coupled to the ring spindle and taken with rotation of the same becomes.
  • the spindle speed is transmitted synchronously by this magnetic coupling to the swirl element.
  • This known device ( Textilpraxis International 1982, January, pages 19 and 20 ) gives the thread in the spinning zone a false rotation by the contacts of the thread when passing through the swirl element and the edge of the spindle top part.
  • a rotating yarn guide 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.
  • this known device has not been able to introduce in practice, since the external drive is too expensive and, moreover, no defined rotation distribution takes place.
  • the object of the invention is to avoid these disadvantages of the prior art and to provide a device which is able to ensure a better and defined rotation propagation to the spinning triangle.
  • the device should also be simple and easy to use at the same time.
  • the rotation imparted by the spindle is amplified between the thread guiding device and the drafting device outlet.
  • the rotation propagates until just before the drafting system exit and leads to a rapid solidification of the exiting roving.
  • the driver is designed as a helical coil, since the helical coil prescribes a defined looping the thread. Operating errors are prevented.
  • the braking effect can be reduced or increased.
  • the winding angle ⁇ of the helix is suitably between 360 ° and 720 °, preferably about 540 °, in order to achieve optimum damping.
  • the upper and the lower end of the helical coil 13 is formed as an edge which lies in a plane perpendicular to the axis of rotation of the helical coil and is suitably rounded.
  • the encapsulation of the swirl element not only the swirl element and the thread run is protected, but it will be avoided in thread breakage or knots of the thread.
  • this encapsulation allows automatic threading by means of suction, which leads to savings in service times during yarn breakage.
  • the eccentric arrangement of the thread inlet bore has surprisingly led to the formation of no balloons between thread guide and drafting.
  • the eccentricity expediently depends on the radius of the core of the driver.
  • the centric arrangement of Fadenauslassibohrung causes a vibration-free twist distribution.
  • it has proven to be expedient to arrange the thread guiding device centrally over the end of the ring spindle at a certain distance from the upper end of the sleeve mounted on the ring spindle. In this case, a distance of at least 25 millimeters has proven to be favorable. As a rule, a distance approximately in the size of the radius of the spinning ring has proven itself.
  • the pivoting of the thread guiding device from an operating position into an operating position not only allows a problem-free manual or mechanical withdrawal of the cops, but also serves to maintain and keep clean the thread guide.
  • the thread guide device can be coupled in the operating position with a suction device, which can operate the thread guide simultaneously by its movement into the operating position. In this way, the thread guide is cleaned of flight and threaded through the suction device of the thread for Wiederanspinnen in the thread guide.
  • a crank of the holder of the thread guide the use of rigidly mounted on the ring rail balloon constriction rings is made possible.
  • FIG. 1 an embodiment of a rotating thread guide device is shown in section. It consists of a housing 2 with an eccentrically arranged Garneinlrawö réelle 21, the rotatably mounted in a ball bearing 16 swirl element 11 with a centrally disposed Fadenauslrawö réelle 22.
  • a driver 13 is mounted and rotatably connected thereto, so that this driver 13th with the swirl element 11 rotates together.
  • the driver 13 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.
  • an upper edge 15 and a lower edge 15' is provided, on which the thread guide device 1 continuous thread is applied and is taken on rotation of the swirl element 11.
  • the swirl element 11 with the driver 13 is suitably encapsulated by a housing 2 for protecting the yarn path through the swirl element 11 and to avoid winding or knots in case of yarn breakage.
  • the housing 2 is placed stationarily 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. This allows the thread guide 1 in the dashed line operating position 1 'are pivoted so that the head of the spindle 3 is free and accessible for the withdrawal of the cops and reassembly of sleeves 4.
  • another suction device 5 is arranged in the form of a tube profile parallel to the usual, arranged under the drafting rollers Luntenabsaugung.
  • Each spinning station is assigned to this tube 5, a suction port 51 to which the thread inlet opening 21 of the thread guide 1 in the operating position 1 'applies, so that through the suction device 5 suction air is sucked through the thread guide 1.
  • This induced draft serves for keeping the thread guide 1 clean of flying and similar loose deposits.
  • On the other hand can be placed in front of the centric Fadenausladorö réelle 22 in this way, the high of the spindle 3 thread F, so that it is sucked into the thread guide device 1 and threaded it.
  • the thread guide 1 is folded down from its operating position 1 'in the operating position.
  • the extending from the thread inlet opening 21 into the suction opening 51 thread F is added for the start of the spinning process and applied to the drafting in a known manner.
  • the suction opening 51 can be opened and closed by the movement of the thread guiding device 1 in order to avoid unnecessary air consumption in the operating position. This can be done in a simple manner by the fact that at the thread inlet opening 21 of the thread guide 1, a cam is arranged, which presses the closure of the suction port 51 or operated in any other way, so that the suction device 5 is activated when the thread guide in the operating position. 1 ' to the Suction opening 51 applies, and the suction port 51 is closed again when the thread guide device 1 is pivoted back to its operating position.
  • the spindle 3 facing part of the swirl element 11 is formed as a magnet and forms with the head 31 of the spindle 3, which is also equipped with permanent magnets, a magnetic coupling, 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 a driving of the swirl element 11 through the spindle 3. As a rule, this distance is about 5 to 10 mm.
  • the driver 12 as FIG. 5 shows, formed as a cross or T and consists of the core 12 ', which is wrapped around the yarn guide 100 passing through the thread F, and an edge 14 which is attached as a crossbar the core 12'.
  • This edge 14 takes the entering through the yarn inlet opening 24 thread F and gives him rotation analogous to the spindle speed.
  • the swirl element 10 is rotatably mounted in a ball bearing 16 in the bearing ring 17 on the holder 18. The entrainment is effected by the above-described magnetic coupling between the spindle head 31 and the swirl element 10.
  • the thread is wound around the core 12 'of the carrier 12.
  • the looping takes place once or twice in order to obtain the desired damping.
  • the housing 20 must also be removable for this purpose.
  • only whole or half wraps are possible. A finer gradation would be given if another cross bar as the lower driving edge, for example, 90 ° offset from the edge 14 would be provided.
  • the driver 13 When running in FIG. 1 Therefore, the driver 13 is formed as a helix, as in FIG. 2 shown in detail.
  • the helical coil 13 has at its upper end an edge 15 as well as at its lower end an edge 15 ', over which the thread F in the helical coil 13 in or out of the helix runs out.
  • the two edges 15 and 15 'of the winding angle ⁇ of the helical coil 13 is exactly defined and the wrap around the core 13' automatically set.
  • the thread is, as described above, sucked, automatically lays down in the course of the helical coil 13, and the desired wrap is made.
  • the edges 15 and 15 ' are preferably formed as a rounded web.
  • the damping acts in the following manner: Although the friction of the thread due to the wrap on the driver 12 and 13 is a stronger Train demanded by the thread balloon, with the result that the balloon is smaller. Ballon constriction rings and their motion control are unnecessary. At most they are still necessary for the turn of Kopsansatzes. On the other hand, the tension in the spinning zone between the thread guide device and the drafting system is substantially reduced, since it is retained by the friction on the driver 12 or 13. In particular, stress peaks, which form through runners and balloon and very often led to thread breaks, are eliminated from the spinning zone.
  • the wrap on the driver inhibits the propagation of the rotation in the direction of the thread balloon / spinning ring. It arises in the thread part F '( Fig. 6 ) a rotation jam through which the fibers leaving the drafting system are given rotation and immediately solidified. It has been shown that it depends on the rotation propagation in the direction of drafting device output in which direction the wrapping of the core 12 'or 13' of the driver 12 or 13 takes place.
  • a wrap against the direction of rotation of the spindle 3 has promotional effect for the propagation of rotation in the direction of the drafting system output. It is therefore important for the operator to ensure that the looping takes place not only in a desired wrap angle ⁇ but also in the correct direction.
  • the driver 13 according to FIG. 2 is not only the desired wrap angle ⁇ , but also the correct direction automatically performed during threading by the helical coil training. Operating errors are excluded.
  • the functioning of the thread guiding device is as follows:
  • the thread F 'running out of the drafting device passes through the thread inlet opening 21 or 24 into the housing 2 of the thread guiding device 1 or the housing 20 of the thread guiding device 100 and leaves through the yarn outlet opening 22 and 23, the Fadehtagen issued.
  • the peripheral with the driver 13 edges 15 and 15 'or driver 12 with edge 14 detect the passing through the housing 2 or 20 extending thread F and grant this by entraining rotation corresponding to the spindle speed, since the spindle 3 via the magnetic coupling Twist element 10 or 11 drives.
  • the thread F leaving the swirl element 10 or 11 runs over the thread balloon in usually under the revolving on the spinning ring 62 runners 63 through to winding on the sleeve 4.
  • the compensation of the difference between the angular velocity of the spindle 3 and the angular velocity of the rotor 63 takes place after the thread F has left the swirl element 11 or 10 in the direction of the runner / spinning ring.
  • the thread F can move freely in the space between the spindle head 31 and the swirl element 10 and 11, so that this compensation is continuous, in contrast to the known from the prior art measures for rotation propagation.
  • the thread F should be able to move as freely as possible here, while 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 Auffraum.
  • FIG. 6 is the entire spinning unit including the spindle 3 with its storage 32, and the ring rail 6 and the spinning ring 62 shown schematically.
  • balloon constriction rings 61 are rigidly mounted on the ring rail 6. Since balloon constriction rings 61 are required as a result of the thread guiding device according to the invention at most when winding the Kopsansatzes can be dispensed with a separate motion control. When winding on the Kopsspitze, however, the balloon constriction 61 would be hindered by the holder of the thread guide 1 and 100 in its movement.
  • a cranked holder 181 is provided for the thread guide device 1 and 100, which passes through the balloon constriction ring 61 so that the distance for the magnetic coupling of the swirl element 10 and 11 is made possible, on the other hand but the balloon constriction ring 61 with the ring rail 6 can take the necessary for the winding upper position, the in FIG. 6 indicated by dashed lines.
  • FIG. 7 shows a further embodiment of a housing 200 of the thread guide 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 described embodiments, such as the driver 12 or 13.
  • Other embodiments of the driver for example, as an eye or in a similar manner, realize the inventive idea and the achieved function in the same way.
  • the invention is not limited to the described application in conventional ring spinning.
