Definitions

  • the present invention relates to a device for producing fancy yarns on process machines through the targeted production of short thick spots in the yarn through short-term Yarn overfeed.
  • the HemaSlub device can be integrated into the air texturing process Delivery plant with electronically controlled pressure rollers and a fancy yarn generator. This delivery plant can be attached to various machines and is easy to use, but it is relatively complex and expensive and can only be used in a thread run with unheated godets become.
  • the system with the thread deflection lever is simple and inexpensive, it is but can only be used to a limited extent because only relatively small thread deflections are possible.
  • a device for lateral thread deflection which is a motor-driven, controlled thread guide with adjustable Stroke, wherein a movement of the thread guide in one direction is easy Underdelivery and in the other direction causes a strong overdelivery of the thread.
  • a first preferred embodiment of the device according to the invention is characterized in that that the thread guide on a flexible and stiff in the direction of stroke Organ, preferably formed by a wire rope, a string or a belt, traversing element attached and driven by this.
  • This preferred embodiment is of the type described in EP-A-0 453 622 and EP-A-0 829 444 described thread laying for winding a thread on a bobbin. Since this System has a very low mass, very steep flanks of the flames can be achieved become. In addition, high yarn speeds can be achieved due to the high dynamics. Since it is a regulated drive system, almost any one can Acceleration and speed profiles can be realized.
  • a second preferred embodiment of the device according to the invention is characterized in that that the thread guide is formed by an oscillating lever or is arranged on such.
  • Thread laying can be particularly suitable for short flames because of the stroke of the Lever is naturally smaller than that of the traversing element formed by a flexible organ.
  • a third preferred embodiment of the device according to the invention is characterized in that that the thread guide stores one of the desired lore appropriate thread length in the form of a loop.
  • a fourth preferred embodiment of the device according to the invention is characterized in that that the drive of the thread guide when the stored thread length is released controlled depending on the volume and the length of the thick point to be generated is.
  • a fifth preferred embodiment is characterized in that the thread guide after creating a thick spot when returning to the deflection position for the next delivery is driven as slowly as possible.
  • the invention further relates to the use of the device mentioned on a false-wire texturing machine.
  • the device for lateral use is preferably used in this case Thread deflection in the thread run immediately before the machine's heating element runs in arranged.
  • the invention also relates to the use of the device mentioned on an air texturing machine.
  • the device for lateral use is preferably used in this case Thread deflection arranged immediately in front of the air texturing nozzle.
  • Fig. 1 shows an inventive unit A for the production of fancy yarn, which in the Type of thread laying described in EP-A-0 453 622 and in EP-A-0 829 444 is.
  • the unit A consists essentially of a base plate 1, one on one Traversing element 2 attached thread guide 3 and its drive and guidance.
  • the thread guide 3 is driven to oscillate in the direction of arrow P by the traversing element 2.
  • the Traversing element 2 is a flexible and rigid organ for transmission in the traversing direction P. of tensile forces and, for example, by a string, a wire, a metal rope, a flat, toothed or V-belt, a metal band, a chain or the like is formed.
  • the Traversing element 2 runs over two deflection rollers 4 and 5 and mounted on the base plate 1 Via a drive wheel 7 driven by a servo motor 6, preferably a stepper motor. It wraps around the drive wheel 6 with several turns and is at both ends on this attached.
  • the motor 6 is an encoder 8 for detecting the rotational position of the drive wheel 7 and thus the Traversing position of the thread guide 3 assigned.
  • the encoder 8 is one of a transmit and a receiving diode existing photoelectric sensor that detects the movement of a Driving wheel 7 rigidly connected disc (not shown; see in this context the US-A-5 918 829). For this purpose, this disk can be scanned with suitable optics Markings, for example with holes or slots arranged along a circle, Mistake.
  • the sensor signal is fed to a controller 9, which checks whether the engine 6 runs at the speed provided for the respective position of the thread guide. In the event of deviations The controller sends a corresponding control signal between the actual and setpoint Engine 6 off. Another output M of the control 9 is connected to the machine control.
  • the unit A serves as a means for lateral deflection of a machine machine passing through it Thread F, in order to transmit the thread in the subsequent process stage cause.
  • the unit is arranged so that the traversing direction P is essentially approximately runs perpendicular to the thread running direction T. In terms of function, it has a certain similarity to a weft store for an air jet loom that has a certain length of thread saves in the form of a loop and then releases it in a controlled manner.
  • the take-off speed v 2 and thus the delivery speed to the next process stage is greater than v 1
  • the difference between v 2 and v 1 depends on the speed of the thread guide 3.
  • the time, duration and speed of the movement of the thread guide 3 are controlled by the controller 9 and synchronized with the delivery speed of the yarn F, the encoder 8 monitoring the parameters mentioned. Because of the controlled drive of the thread guide 3, almost any acceleration and speed profiles can be created. In addition, because of the low mass of the thread guide 3 and its drive, very steep flanks of the flames can be achieved.
  • the thread length deflected by the thread guide 3 determines that available for a flame standing tradition, so that for a shorter flame a smaller one and for a longer one Flame a larger deflection of the thread with appropriate positioning of the thread guide 3 is done. If there is a tradition in the embodiment of Fig. 1 and the thread guide 3 from the illustrated deflection position into the dashed line denoted by 3 ' Has been moved, it must then be in the position required for the next flame Deflection position can be moved. This is done by moving back very slowly the yarn section until the next flame. This return movement is with an underdelivery connected, which is not annoying because the yarn section to the next flame in the Usually by orders of magnitude longer than the flame itself. For example, the length of the flame is 70 mm and the length of the following piece of yarn without flame 5 m or more.
  • one of a flexible traversing element driven thread guide also an aggregate with an oscillating drivable swivel lever can be used.
  • This pivot lever can for example be of the type of thread laying lever described in EP-A-0 838 422, wherein on the energy storage to influence the deceleration or acceleration of the thread laying lever can be dispensed with in reversing its movement. Also one of those The pivot lever would be driven by a servo motor with an assigned encoder. Because naturally the stroke of the pivot lever is smaller than that of the thread guide 3 of the Unit A, would be the unit with the swivel lever in use on short flames limited.
  • FIG. 2 and 3 each show an example of the use of the unit A on a false wire or air texturing machine. According to FIG. 2, this also runs as friction texturing designated false wire texturing process the raw yarn drawn from a bobbin 10 F a first delivery mechanism 11, a radiator 12, a cooling rail 13, a friction unit 14 and a second delivery unit 15 and is finally fed to a winding unit 16.
  • the elongated radiator 12 shown can also be by a heating godet, that is a heated roller wrapped by several turns of the yarn F may be formed.
  • the unit A is arranged between the first delivery unit 11 and the heating element 12. at The false wire texturing twists the yarn and in the twisted state by heating and then cooling thermally fixed. After opening, the filaments form its fixed helix structure is a yarn of high volume and high elastic extensibility.
  • the rotation is preferably transmitted using a three-axis disc friction unit, whose axes are parallel to the thread running direction and the corner points of an equilateral Form a triangle.
  • the raw yarn F here designates core and fancy yarn, but only the fancy yarn is deflected by unit A.
  • the texturing zone and the stretching zone identical to it extend from the first to the second delivery unit 11 or 15, the swirl zone from the first delivery unit 11 to the friction unit 14 and heat-setting zone from the entrance of the radiator 12 to the exit of the cooling rail 13th
  • FIG 3 shows a view of the worktop 17 of an air texturing machine, on which, among other things, an air blowing texturing nozzle 18 and, in the thread running direction T, the unit A are arranged directly in front of it.
  • the supplied filament yarns F 1 and F 2 are integrated in the air-texturing nozzle 18, with F 1 denoting the so-called core yarn and F 2 the fancy yarn.
  • the core yarn F 1 runs via heating godets 19 and 20 to a thread brake 21 and then passes into the air blast texturing nozzle 18.
  • the fancy yarn F 2 runs via heating godets 22 and 23 to the unit A and from there to the air blast texturing nozzle 18.
  • the fancy yarn produced in this way passes from the air blowing texturing nozzle 18 via a take-up roll 24 to a take-up spool 25.
  • Fig. 3 clearly shows that the unit A because of its simple Construction and its small footprint easily in a standard thread run with Heating godets can be installed. Of course, installation in a thread run also offers no problems with a flat radiator.
