Definitions

  • the invention relates to a twisting machine according to the preamble of claim 1.
  • Such a twisting machine is e.g. known from DE 35 07 711-A1 (Bag. 1390). It is a cording or cabling machine in which an outer thread is guided in a balloon around the stationary spool of the inner thread and in which the two threads are then combined in the twisting point and twisted together.
  • the quality of such a thread depends on the fact that the thread geometry in the thread point is established in a certain way and remains as constant as possible during the whole process.
  • DE 36 28 654-A1 discloses a method for determining the twist structure of a thread, in which the thread is scanned in the longitudinal direction and the time course of the scanning signal is examined for periodic components. From this analysis, parameters are obtained through which e.g. the thread amplitude and thus the quality of the thread is determined.
  • This method is not suitable for bulky or other threads in which the structure achieved by twisting does not appear due to the bulk or softness of the thread. This method is therefore also not applicable to continuous filaments which consist of a very large number of very fine individual filaments, or to spun threads which are made from staple fibers.
  • the object of the invention is to design the twisting machine in such a way that an operationally reliable determination of the twisting result, which is independent of the type of thread, is possible during operation, with a low technical outlay being sought.
  • the possibility should be given to use the current measurement result to control or regulate the machine.
  • the twisting machine can be constructed in such a way that several pay-off spools sit on a common twisting spindle and circle around the twisting axis (US Pat. No. 4,754,599-A1) (AR 86/1).
  • the inner coil is floating, i.e. not rotatably supported on the twine axis.
  • the outer thread is guided in a balloon around the inner bobbin and then combined and twisted with the inner thread in the area of the twisted axis.
  • claims 7 and 8 show a solution for measuring the delivery speed of the inner thread.
  • the measured values continuously generated on the twisting machine can be continuously written down to characterize the twisting result and can be related to one another.
  • the difference of the quotient or quotas from the delivery speeds can be considered as such a relationship.
  • a quality statement can be generated by recording current records and evaluating these records.
  • the cord spindle 1 shows a cabling or cording device with the cord spindle 1 and the winding in the form of the take-up spool 15.
  • the outer thread 4 coming from the supply spool 27 runs centrally into the cord spindle 1 from below via an outer thread brake 14.
  • the cord spindle 1 is driven by the drive motor 3.
  • a bobbin holder 28 is floating so that it does not rotate with the cord spindle. He will e.g. held in place by a magnet, not shown.
  • the outer thread 4 inserted centrally into the cord spindle 1 from the bottom exits radially on a rotating storage disk 29, which is attached to the spindle, and runs with the formation of a thread balloon 5 up to the cord point 7, where it connects with the inner thread 6 to the cord thread or cable 12 united.
  • the cord 12 runs through the thread guide eyelet 16, which is arranged above the cord spindle 1 in its axis as a head thread guide, to the take-up spool 15.
  • the inner thread 6 is drawn off from the inner bobbin 17 indicated by dashed lines and meets the outer thread 4 at the cording point 7.
  • the inner coil 17 is placed on the floating coil holder 28.
  • the inner thread brake 8 which is operatively connected to an adjustment drive 9, by means of which its thread speed is adjusted to that of the outer thread 4 before it meets it at the cord point 7.
  • the adjustment drive 9 supplied with energy, for example, by a battery accommodated in the tip of the pot lid 11, can be switched on and off, as well as its amplification or reduction Braking force be reversible effective direction.
  • the receiver 10 of the remote control which is used to adjust and adjust the inner thread brake 8, is likewise arranged inside the thread balloon 5 near the inner thread brake 8, for example, as indicated in FIG. 1, in the tip of the pot lid 11 and supplied with power from the aforementioned battery.
  • the adjustment of the thread speeds by means of the remote control 10, 13 can be effected by influencing the braking effect of the inner thread brake 8 in such a way that the angles which the inner thread 6 on the one hand and the outer thread 4 on the other hand form in the cord point 7 with the cord thread 12 running out of the cord point 7, be harmonized as much as possible and remain constant. Due to the arrangement of the adjustment drive 9, which is connected to the inner thread brake 8 and can be actuated by the remote control, this adjustment can be carried out while the cord spindle is running.
  • Figures 2 and 3 show the inner thread brake 8 in side view and in front view.
  • the inner thread brake 8 is mounted on the top of the pot lid 11. It lies under an annular balloon deflector 23 placed on its housing 22, which prevents the ballooning outer thread 4 from touching the inner thread brake 8.
  • the inner thread brake 8 has two rotatably mounted clamping rollers 20 and 21 which are elastically superimposed on one another with their circumference and which clamp the thread between them in the event of partial wrap.
  • the thread running out of the inner bobbin 17 is pulled through a central thread guide 30 attached to the pot 2 and guided to the first pinch roller 21, then wraps it up to the pinch point with the pinch roller 20, then loops it partially (20) and becomes the balloon deflector to the thread roll 24, which is rotatably mounted essentially centrally above the balloon deflector 23, and from there to the cording point 7.
  • the thread roller 24 and the pinch roller 20 are freely rotatable.
  • the pinch roller 21 serves as a brake roller and can be braked, for example, by an adjustable hysteresis brake 31-33.
  • the brake roller 21 is connected to a rotating hysteresis disc 31 made of a ferromagnetic material.
  • the end face of the hysteresis disc 31 lies opposite a brake magnet 32.
  • the brake magnet 32 is a permanent magnet. It is mounted on a threaded nut 33 which is guided on a threaded spindle 26 and is in engagement with it.
  • the threaded spindle 26 is driven by the electric motor 18 via an intermediate gear 19 and the gear pair 47, 48. The distance between the magnet and the hysteresis disk 31 can thus be adjusted.
  • the electric motor 18 with the gear 19 attached is laterally attached to the housing 22 of the inner thread brake 8 on a mounting boss 25 provided on the housing 22. It is powered by the battery mentioned in the top of the pot lid. Switching the adjustment drive 9 on and off and reversing its direction of action are carried out by the transmitter 13, which is fixedly attached outside the thread balloon 5, and by the receiver 10. The receiver 10 connected to the adjustment drive 9 is arranged in the top of the pot lid and is taken from the battery fed.
  • the outer thread brake 14 is also designed as an overrun roller that can be braked. Braking can also be done by a hysteresis brake that can be adjusted by hand.
  • both the overflow roller 14 of the outer thread brake and the clamping roller 21 of the inner thread brake are provided with a tachometer.
  • An inductive or optical sensor 34 or 35 serves as a tachometer for both rollers 14 and 21.
  • the sensors 34, 35 scan the end faces of the rollers 14 and 21, respectively.
  • the output signal of the sensor 34 is fed to a gate 36 via a line.
  • the embodiments of Figures 4 and 5 differ essentially in that in Fig. 4 within the thread balloon 5, the signals from the sensor 35 are amplified in the amplifier 38 and are transmitted contactlessly from the transmitter 39 to the receiver 40, from where they are to a Line with the receiver 40 connected gate 37, while in the embodiment according to FIG. 5 the sensor 35 is provided outside the thread balloon 5 and is directly connected to the gate 37.
  • Transmitter and receiver 39 and 40 can function by means of light rays, electromagnetic waves, magnets.
  • a magnetic insert and an inductive sensor 35 can preferably be used in the end face of the roller 21 in FIG. 4, while a scanning by optical means or by electromagnetic waves is preferred in FIG. 5.
  • the pulse signals i a and i received by the gates 36, 37 are compared with time-constant frequency signals f of the timer 41.
  • the output signals of the gates accordingly represent on the one hand the round trip time t a of the overflow roller 14 of the outer thread brake and on the other hand the round trip time t ; represents the brake roller 21 of the inner thread brake.
  • These rotational speeds n a and n represent the Ge speeds with which the outer thread or the inner thread are drawn off from the bobbins 27, 17, respectively.
  • These signals are further differentiated and the quotient is formed in the evaluation circuit.
  • This output signal can be used on the one hand to produce a record 42 and / or to actuate an alarm transmitter 43.
  • a differentiation with a predefined setpoint value S can take place in a comparator.
  • the output signal R is then used via the transmitter 13 and the receiver 10 as well as an amplifier 46 to control the adjustable brake of the brake roller 21.
  • a shoe brake 44 is provided as the brake (unlike in FIG. 2), which acts on the shaft of the brake roller 21 and is pressed on by a magnet 45.
  • the hysteresis brake described with reference to FIG. 2 can of course also be used.
  • the feedback signal R serves to control the electric motor 18, which drives the threaded spindle, with which the distance of the permanent magnet 32 from the hysteresis disk 31 is set.
