  • These device parts of all spinning stations are usually via a common drive or a small number of common drives and are for individual spinning positions (thread break, Can change) can be disconnected from this drive.
  • the spinning machine has refinement means, ie means for refinement Stretching such longitudinal structures or means for dissolving such longitudinal structures.

  • For driving the refiners Usually provided for or as a single central drive for yarn formation a small number of drives, each with a drive function of the refinement means take. But it is also known for every spinning station or even in every one Spinning station to use separate small drives for each drive function.
  • Means for refinement before yarn formation by stretching the feed Longitudinal fiber structures have, for example, three pairs of cylinders arranged in series, which are driven in the conveying direction with increasing peripheral speed. Such pairs of cylinders extend, for example, along a series of Spinning stations and are, for example, by appropriate gear from one single drive or there is one for each pair of cylinders (drive function) separate drive provided.

  • Such drafting devices obtain the longitudinal fiber structures from storage containers (cans) and lay the produced ones Longitudinal fiber structures also in storage containers from which the Longitudinal fiber structures finally a spinning machine or a spinning station be fed.
  • the management of these storage containers is very complex, especially if it is to be carried out fully automatically. Without automation or with only partial automation is the management of the storage containers labor intensive and prone to errors.
  • the object of the invention is to create a spinning machine, the yarns can produce high regularity with regard to fiber mass per unit length, even if the fiber material fed to the spinning positions is less high Has regularity than for known spinning machines for the same Yarn quality would have to be required.

To do this, a spinning station as a whole for driven an increase or decrease in their performance.

  • Another advantage of the spinning machine according to the invention is that for the Spinning (after thread break or can change) refining agents and if necessary, yarn forming agents can also go through a piecing cycle is completely independent of other spinning positions and in which the speeds of moving parts, for example, increase continuously. This is the piecing significantly easier than with state-of-the-art machines in which moving parts only when spinning onto one with constant speed running drive can be coupled, resulting in a stepped or leads to at least a very steep increase in the corresponding speeds.
  • sensor means of the spinning machine according to the invention detect each spinning position the fiber mass in the area of the entrance of the refining agent and the infeed speed becomes a refinement agent through appropriate Control of the refining agent varies accordingly.

  • Fluctuations in the fiber mass is essentially the delay in the spinning station Fiber mass varies, in that the speed of entry of the fiber mass into the Spinning station and / or the speed at which the yarn runs out of the spinning station is controlled or regulated accordingly.
  • the fiber longitudinal structures become the spinning positions advantageously supplied from cans or from coils, so that devices that the Longitudinal fiber structures deliver from fluctuations in the entry speed into the Spinning positions are not affected.
  • Ring spinning, open end and friction spinning processes are less suitable for the above outflow regulation described, since for these processes the yarn properties in only narrow areas are independent of the spinning speed. A wider one Area in which the yarn properties are independent of the spinning speed, still has the pot spinning process. However, this procedure is because of relatively large, rotating masses not very much for a discharge regulation suitable.

  • the spinning station has its own drafting device 1 (refining agent 1) as an internal spinning station with, for example, three cylinder pairs (inlet cylinder 2, middle cylinder 3 with straps 4 and outlet cylinder 5).
  • the spinning station has a yarn-forming means 6, which for example consists essentially of a nozzle arrangement 7 and a pair of draw-off cylinders 8 for an air spinning process, and a yarn winding device 9.

  • the speed of the engine M.1 is variable and is detected by a speed sensor Z.1.
  • the engine M.1 is by means of Control data from the control and monitoring unit 12 based on the measurement data of Sensors 10 and 11 are generated, controlled.
  • Outlet cylinder 5 of the drafting device 1 and take-off cylinder 8 of the yarn forming means 6 are operated by a further motor M.2 driven such that their peripheral speeds are one for the present Have a suitable yarn formation ratio (spinning delay).
  • the speed of this other motor M.2 is detected by the speed sensor Z.2 and with suitable means kept constant.

  • the control and monitoring unit 12 processes the measurement data of the in a manner known per se from regulating drafting systems Sensors 10 and 11 to control signals based on the speed of the first motor M.1 is regulated. This will cause a suitable delay due to the Sensor 10 compensated for irregularities in the fiber mass Variation of the inlet speed (inlet cylinder) and variation of the draft between center cylinders 3 and outlet cylinders 5 (variable draft 20). With This control can be used to correct short-wave irregularities in particular be evened out. Irregularities in fiber mass from downstream sensor 11 on the finished yarn are detected in processed in the same way, which is a regulation that can not even out short-wave irregularities.
  • the spinning station shown in FIG. 1 thus has a controlled in a known manner or regulated drafting system, the infeed speed being varied and the The outlet speed is constant, that is, the yarn formation with constant Delivery speed can be operated.
  • the outlet speed is constant, that is, the yarn formation with constant Delivery speed can be operated.
  • a spinning machine therefore has a large number (for example two hundred) spinning stations, all of which are equipped, such as those in the Figure 1 shown spinning station.

At least those are assigned to each spinning station individually Pairs of inlet cylinders 2 and middle cylinders 3 of the drafting system, the sensors 10 and 11 and the first motor M.1 or a stepless replacement for this motor controllable gear between a central drive and each spinning station.
  • the fiber longitudinal structures from the spinning positions Supply containers fed.
  • a direct and continuous feed for example from a card or from a draw frame is only possible if between the Spinning station and the upstream device a buffer with a sufficiently large Buffer capacity is arranged, with which buffer variations in the Infeed speed can be bridged into the drafting system without that too the upstream device must be controlled accordingly.
  • Such a Buffer can simply be designed as a free sag of the longitudinal fiber structure, which sag is monitored by sensors.
  • the spinning station When exceeding a lower or upper limit of the buffer capacity, the spinning station is stopped or a Upstream device (card, drafting system) controlled accordingly, so that Delivery speed to the fill level of the buffer and / or to the Infeed speed in the spinning unit internal drafting system is adjusted.

  • FIG. 3 shows a spinning station for a spinning machine according to the invention, in which spinning station the control / regulation according to FIGS. 1 and 2 are essentially combined. While the motors M.1 and M.2 have variable speeds and are controlled by the control and monitoring unit 12, only the middle cylinder pair 3 is operated by a third motor M.3 at a constant speed. This results in two places of variable delay 20 and 20 '. For such control / regulation of the spinning stations, limit values must be specified for the first variable warping, the second variable warping, the spinning speed, further spinning parameters and, if appropriate, for buffer capacities upstream of the drafting unit 1.
