Definitions

  • the invention relates to a spinning device with a spool attached to a rotating spindle, as specified in the preamble of claim 1 is.
  • the invention further relates to a control and a control device for such a spinning device.
  • Spinning devices of the type mentioned are known from DE-OS 41 03 369, which shows the closest state of the art.
  • the thread is guided inside the spinning or twisting ring is so that it doubles as a balloon restrictor serves.
  • the lower area Forehead provided an eyelet-like thread guide, the can be an inwardly projecting component.
  • the spinning or twisting ring moves to a larger axial Length of the coil extends and to stabilize it via two axially spaced magnetic bearings is kept floating, with both Magnetic bearings are radially active magnetic bearings.
  • DE-A-24 20 825 generally known magnetic bearings of rotors
  • the object of the invention also relates to a control device and a regulating device, that allow to take advantage of Optimal use of the spinning device according to the invention.
  • the radially active, axially passive magnetic bearing that rotationally symmetrical element on its lower part includes, for example, a magnetic bearing, the at least partially made of ferromagnetic material existing element in its axial direction by means of a axially magnetized permanent magnets surrounding it holds floating and in the radial direction by means of electromagnetic ring arranged around it Medium stabilized.
  • electromagnetic means can be excited by means of an electronic control device, which is connected to sensors, the radial deviations of the rotationally symmetrical element.
  • the radially stable, axially unstable magnetic bearing can on the other hand, from two ring-shaped, concentric to the axis the coil arranged permanent magnets consist of which one is attached to the collar and thus with rotates with the element and the other, opposite the first, is firmly attached from the outside.
  • the rotationally symmetrical element is thus axial Directionally suspended in the axially unstable magnetic bearing.
  • the interplay gives it its axial stability of the two magnetic bearings.
  • the sensors for detecting the axial deviations of the rotationally symmetrical element serve in connection with the downstream electronic device Measurement of thread tension.
  • the collar at the top of the rotationally symmetrical Element serves on the one hand to attach the upper one Magnetic bearing, but also leads to one Calming the air circulation inside the element, which has an energy-saving effect.
  • the energy saving effect is even more pronounced with one very advantageous embodiment of the spinning device, the one facing the incoming thread Front of the rotationally symmetrical element through the collar is closed except for the recess.
  • the centrally arranged thread guide through the central one Cutout formed and therefore rotates with the element With.
  • the friction of the thread on the thread guide such as it occurs with a fixed thread guide, and the not only negatively affect the rewinding process, but also on the process of spinning (it arises disruptive torque on the thread), does not apply this version of the element according to the invention. It remains only that from the longitudinal movement of the thread resulting friction.
  • the twist of the thread resulting from the winding now plants itself unadulterated in the spinning zone away. This results in a high yarn tenacity in the spinning zone with a low thread tension level, higher Yarn stretch, less hairiness and finally also lower thread break counts.
  • this is rotationally symmetrical element, tapering upwards, conical.
  • the aim is to To include the spindle with the smallest possible distance. Of the achieved smaller, mean diameter of the Element acts due to the lower moment of inertia energy saving.
  • a very advantageous embodiment of the spinning device is designed according to claim 4 such that the axial relative movement between rotationally symmetrical Element and spindle is made so that the spindle when winding the yarn into the rotationally symmetrical Element is inserted.
  • the winding process starts at the bottom Part of the coil, and element and coil move in such a way that the winding process continues upwards.
  • the growing coil is outside of the rotationally symmetrical element, which has the consequence that the aerodynamic losses increase with length and the diameter of the coil increases significantly.

  • the piecing phase occurs an additional, undesirable Traction on the thread.
  • An embodiment can be used to avoid this thread load serve, in which the most rotationally symmetrical Element arranged and leading the thread to the bobbin Thread guide as the circumferential on the inner circumference of the element Runner is trained.
  • This embodiment is particularly suitable for measuring the thread tension by means of the sensors and the downstream electronic device.
  • a relative movement between Runner and rotationally symmetrical element occurs with this version only during the piecing phase. Because of its low inertia, the runner becomes the Follow rotation of the driven part very quickly but at the same rotational speed two parts relative to the rotationally symmetrical element don't move anymore. The situation after the piecing phase is thus the same as that of a fixed element Thread guide, so that during spinning no difference to the embodiment of the element results with a fixed thread guide.
  • the longitudinal extent of the rotationally symmetrical element allows this with an electric motor Drive. Its sole use - and not also the drive of the spindle - is included to the extent that the spindle is advantageous because of its smaller scope and weight a lower moment of inertia has as the rotationally symmetrical element, so that the thread tension in the piecing phase is lower is than with the sole drive of the spindle.
  • the control program contains the sensors Measurement of the thread tension gained knowledge of the usual during piecing and during the spinning phase (Here, for example, due to the changing torque the bobbin) changing thread tension, the by changing the drive torque accordingly Spindle and / or rotationally symmetrical element low can be held.

This movement can be done either axially Move the foot bearing 7 with the pot 3 stationary or by moving the pot bench 11 axially stationary foot rest 7. Also an overlay of both Transport movements are possible.
