Definitions

  • the invention relates to a method for operating a ring spinning machine and a ring spinning machine, the drafting systems of which are pneumatic Compression devices are equipped.
  • the invention has for its object to a ring spinning machine operate that the possible performance can be used optimally.
  • the ring spinning machine By specifying a limit for the hairiness of the spun Yarn it is possible to find a compromise between substance use the fiber material on the one hand and the wear on the rotor and / or ring on the other hand to find the ring spinning machine with the highest possible Power can be operated.
  • the one for a certain fiber material suitable limit can be taken into account the parameters mentioned empirically determined in particular at the manufacturer of the ring spinning machine and then be given to the users of the ring spinning machine.
  • the Hairiness of the yarn to be spun is adjusted to the limit.
  • a regulation ensures that the entire cop trip uniform conditions exist.
  • a ring spinning machine In a ring spinning machine, the object is achieved in that means for Maintaining a specified hairiness of the yarn to be spun are provided. These funds can be with a controller or with a Regulation can be realized. They also contain means for varying the Compaction effect of the pneumatic compression device by the Control or regulation to achieve or maintain the limit value the hairiness of the yarn to be spun.
  • the drawings 1 and 2 each show a schematic representation Spinning station of a ring spinning machine, the drafting system of which pneumatic compression device is equipped, the Compaction effect is adjustable.
  • the drawing 3 shows a module of a Saug direes.
  • a modern ring spinning machine has a large number on both machine sides of spinning positions, for example on each machine side 500, of which is shown in the drawings.
  • Each of these spinning positions contains a drafting system 13 with a compression device, on the one Ring spinning device 14 with a ring 26 follows, on which a rotor 27 is led.
  • the fiber material 11 to be spun is drawn off from a roving bobbin 10 and runs into the drafting arrangement 13 via a deflecting rod or deflecting roller 12 on.
  • the drafting system 13 has an input roller pair made of an in Machine longitudinal direction continuous, driven lower cylinder 15 and a pressure roller 16. Furthermore, it has a pair of central rollers from an in Machine longitudinal direction continuous, driven lower cylinder 17 and a pressure roller 18. These form a double apron unit with a Lower straps and an upper strap. Then follows Output roller pair of a driven perforated roller 19 and one Printing roller 20.
  • the perforated roller 19 is a further printing roller 24 assigned.
  • the stretched when it reached the pressure roller pair 19, 20 The fiber structure runs between the perforated roller after leaving the clamping line 19 and pressure roller 24 through a thread guide 28 to the rotor 27, at which the fiber structure is redirected and led to cop 30, which on a spindle, not shown, is arranged in the circumferential direction is driven.
  • a suction insert 21 is arranged inside the perforated roller 19 and is connected to a vacuum source, for example a blower 22, is connected.
  • the Suction insert 21 has one on the area between the two Pressure rollers 20, 24 of the perforated roller 19 directed suction slot, the straight in the transport direction of the fiber material 11 or at an angle to it runs.
  • Suction insert and suction slit each have a special effect on the Thickening and thus on hairiness.
  • different slot shapes and suction inserts are hereby again our previous applications, e.g. DE 100 32 503.3 for a special one Slit shape and DE 199 09 499.3 and DE 199 46 089.2 for suction inserts directed.
  • the distance of the Determine the suction slit from the sliver influences in to a large extent the hairiness of the yarn, so it is beneficial in every Execution of the machine described are taken into account. So is conceivable that the spinner for each yarn count, especially suitable suction inserts can be given with which he can adjust the hairiness as required, the rule of thumb being: each the finer the yarn, the smaller the distance between the insert and the sliver, the lower the web height. Preferably the dimension will change move approximately from 0 mm for Ne 100 to approximately 1 mm for Ne 10.
  • suction pads with webs of different on the same machine Height can, due to the described effect, that of the usual today large ring spinning machines with many spinning positions appearing Problem of falling from the fan to the last spinning position Negative pressure can be prevented.
  • the suction inserts are preferably how So far, made of a suitable plastic and can be used in one Yarn changes can be changed quickly.
  • the so-called compression zone is located on the outside of the perforated roller 19 a cover 25 opposite through which the pneumatic Compaction effect can be influenced in the compression zone.
  • Pneumatic compression improves substance utilization of the processed fiber material, because more fibers due to the Spinning twist can be incorporated into the yarn. That way Spun yarn has a hairiness that is distinct compared to the hairiness of a conventionally spun yarn is lower.
  • the invention therefore provides that the hairiness of the yarn to be spun is not to the maximum possible minimal hairiness is reduced, but to a limit of hairiness, who found by means of a compromise between different parameters can be. These parameters are the performance of the ring spinning machine (Spindle speed), the improved substance utilization and the wear of Ring 26 and / or runner 27.
  • a control 30 is also provided in the example of drawing 2, with which, however, controls the blower 22 via a frequency converter 35, to vary the vacuum in this way.
  • the regulation 30 receives information about hairiness by the fact that the Hairiness of the spun yarn is recorded indirectly.
  • This indirect Detection takes place in that the temperature of the ring 26 and / or the Runner 27 is detected.
  • the temperature of the ring 26 and the rotor 27 is representative of the frictional action between rotor 27 and ring 26 and thus indirectly also representative of the hairiness of the spun yarn, because the hairiness of the spun yarn is decisive for the friction.
  • the Temperature detection takes place by means of a temperature sensor 33, in particular an infrared sensor.
  • means can also be provided by means of which the hairiness of the spun yarn is recorded directly. This means then expediently between the pressure roller 24 and the thread guide 28 arranged.
  • Actuators 31 and 32, that are adjusted by the control 30 are then designed such that a Group or possibly all covers of the drafting systems on one machine side can be adjusted at the same time.
  • a simple solution provides for an operator to be present the hairiness of one or more spinning positions by means of a measuring device Spun yarns checked and even compared whether the existing ones Settings still result in the required hairiness and this, if Deviations from the limit of hairiness occur, changed manually.
  • the setting of the compression effect is not here either limited to adjusting a cover 25. It also offers at least the options described above.
  • more options for setting the Compaction effect and thus the setting of a value of hairiness disclosed can of course be combined with the present invention individually or in combination with one another be used.
  • the compacting device shown with the perforated roller 19 is also just as an example of a pneumatic compactor too understand. Of course, all other known pneumatic Compression devices can also be used.
