Definitions

  • the invention relates to a combing machine with a plurality of combing devices, a drafting device downstream of the combing devices, which feeds the combed belt to a can press, and to a method for producing a uniform combed belt.
  • the fiber fleece combed out by the combing tools is combined into a fiber sliver via a belt funnel, with a pair of draw-off rollers connected downstream of the belt funnel.
  • These fiber slivers, which are formed on the individual combing heads, are generally transferred parallel to one another via an outlet table to a drafting unit located on the combing machine.
  • the slivers fed are doubled and combined into a single sliver, which is then placed in a can via a can press.
  • the drafting system used in the combing machine has the task of mixing the individual bands or fibers by doubling.
  • the soldering points created by the combing process are compensated for during stretching.
  • the drafting device is provided with a control device for making the sliver belt even.
  • Regulated drafting systems are known for use on special lines, but are new for use in a drafting system on the comber.
  • the advantages achieved in this way are considerable, so that under certain circumstances a drafting system passage or section previously connected to the combing machine can be omitted and the combing belt delivered by the combing machine can be attached directly to a flyer or to an Oe spinning machine. This in turn necessitates increased profitability in the spinning mill area.
  • the combing heads can work continuously even with different mixtures of the feed rolls without readjustment. This, in turn, results in an increased quality of the sliver, since an interruption is no longer necessary and the resulting irregularities are eliminated.
  • the speed control is carried out on a delivery roller of a main drafting zone, no belt store or coordination between the intake roller of the drafting zone and the combing devices is necessary.
  • control impulses of the control device of the drafting device or of the drafting device are transmitted to a higher-level process control computer, which is also connected in connection with the other machines of the manufacturing process.
  • a method or a device is particularly advantageous, wherein a first drafting device is assigned to the individual fiber bands formed on the combing heads and a first draft is carried out.
  • Fig. 1 shows a combing machine 1, for example eight combing heads 2, of which only four are shown in the illustration.
  • a wadding roll 3 On each combing head 2 there is a wadding roll 3, the wadding 4 of which is fed to the combing devices 5 via a feed device (not shown).
  • the combing device 5 is not shown in more detail and, as is generally known, can consist of a pliers unit, a circular comb attached underneath it and a fixed comb with respect to the conveying direction, arranged behind the pliers unit, with subsequent tear-off rollers.
  • the combed nonwoven fabric released by the tear-off rollers passes via a draw-off table 6 into a draw-off funnel, not shown in any more detail.
  • the draw-off funnel the nonwoven fabric is combined into a sliver, or sliver.
  • This process is supported by a pair of draw-off rollers 7 which are arranged downstream of the respective draw-off hopper and which deliver the comb-pull belt to an outlet table 8.
  • sliver guides 9 are provided which are offset from one another in the horizontal direction.
  • the fiber slivers 10 guided parallel to one another arrive at a drafting system 11, a measuring device 12 being provided at the input of the drafting system 11, which measures the strength of the incoming fiber slivers.
  • the measuring device 12 can e.g. optically or mechanically.
  • the slivers After passing through the measuring device 12, the slivers pass between the input rollers 13 of a pre-draft zone 14 to a pair of center rollers 15, which are at the same time the feed rollers for a subsequent main draft zone 16.
  • the drawn strips 10 Via the delivery rollers 17 at the exit of the main drafting zone 16, the drawn strips 10 enter a strip hopper 18, which is shown schematically, and are combined there to form a combed strip 19 with the aid of the extraction rollers 20.
  • a pressure rod 21 is attached in the draft zone to guide the fibers. This pressure rod 21 could also be arranged in the main drafting zone 16.
  • the combed belt 19 delivered by the take-off rollers 20 arrives on a conveyor belt 22 and is transferred to a can press 23.
  • the combed belt 19 is placed in a can 26.
  • the drafting system 11 is provided with a control device 27.
  • the lower rollers of the roller pairs 13, 15 and 17 are driven by the main motor M, a planetary gear 28 being interposed for driving the lower roller 15 and the drive of the lower roller 13 being removed directly from the lower roller 15.
  • a control motor M1 is assigned to the planetary gear 28 and is controlled via a control unit 29.
  • the control device 29 receives pulses from a setpoint value stage 30, in which the measurement voltage initiated by the measuring device via a signal converter 31 and a timing element 32 is compared with the control voltage output by the master tachometer 33 of the main motor M and results in a target voltage for the control unit.
  • a sliver monitor Before entering the calender rolls 24, a sliver monitor can additionally be provided for monitoring the regulated combed belt.
  • the measuring device 12 determines a difference from the nominal value strip thickness, then in this case a time delay is applied via the control device 27 to the control motor M1, which engages in the planetary gear and causes a change in speed of the center roller 15 and thus also of the input roller 13, while the delivery roller 17 has an unchanged speed. That is, the delay is determined as a result of the changed speed difference between the center roller 15 and the delivery roller 17 Band thickness adjusted by the measuring device 12.
