Definitions

  • the invention relates to a thread tension regulating device for a thread guided by a thread spool via thread guiding elements, thread tensioners and thread breakage detectors to the processing area of a knitting machine, with a thread tension meter and a thread brake that is automatically adjustable depending on the display of the thread tension meter.
  • a regulating device of the type mentioned is known for example from US-PS 45 23 440.
  • a thread brake is adjusted in its braking effect by means of an electric motor, the motor being operated depending on the display of a thread tension meter either in one direction of rotation to increase the braking effect or in the other direction of rotation to reduce the braking effect.
  • This braking effect control is intended to achieve the same knitted fabric Pieces always the same thread lengths are processed, so that the same knitted dimensions can be guaranteed.
  • it has been found in these thread tension regulating devices that strong thread tension fluctuations occur due to the many thread guiding devices and thread monitoring devices, via which a thread must be passed from a thread spool to the working area of a knitting machine.
  • the invention has for its object to provide a thread tension regulating device of the type mentioned in such a way that it ensures a safer and more accurate readjustment of the braking force of the adjustable thread brake.
  • a thread conveying device which removes the tension imposed on the thread on its way from the thread spool to the thread brake is arranged in the thread passage direction immediately before the automatically adjustable thread brake and that between the thread brake and the in A thread tensioner known per se is arranged downstream of the thread flow direction.
  • a thread storage feeder which is also known per se can be provided as the thread conveying device.
  • the automatically adjustable brake can at the same time form the thread brake, which the thread tensioner upstream of the thread tension meter must have anyway, so that only thread is actually caught and not thread is pulled from the thread store during the thread winding process.
  • the thread tension regulating device is particularly suitable for use on flat knitting machines, the automatically adjustable thread brake being assigned to the lateral thread take-up tensioner arranged in the area of a needle bed end.
  • All essential to the invention Lichen parts of the thread tension regulating device, namely the thread conveying device, the thread tension meter and the automatically adjustable thread brake associated with the known thread take-up tensioner can be arranged on a common attachment, with which older flat knitting machines can also be retrofitted.
  • the response sensitivity of the regulating device can be increased significantly, even if the friction of the thread during the passage of the thread tension meter is greatly reduced, in that it is guided in the area of the thread tension meter via stationary and movably mounted thread guide rollers, which in any position Moving parts of the thread tension meter keep the thread tension experienced by the thread in the thread tension meter practically constant.
  • the thread tension regulating device shown in the drawing has a common carrier 10 which can be fastened to the machine frame 11 of a flat knitting machine in the region of the end of one of the needle beds 12.
  • a thread storage feeder 13 is fastened to the carrier 10 and has, for example, a thread storage drum 14 that can be driven by an electric motor, on which a certain thread length is kept in stock in individual turns, which - continuously or at intervals - via different thread guide members 15 and at least one thread monitoring device 16 from one a spool table 17 of the flat knitting machine arranged bobbin 18 has been withdrawn.
  • the stored thread can be pulled down practically without resistance via a direction-controlling thread guide eyelet 19, where it arrives in a thread brake 20 of a thread take-up tensioner provided in a known manner with a swivel arm 21.
  • the braking effect of the thread brake 20 can be changed by means of an electric motor 22 which can be operated in both directions of rotation.
  • the thread 25 passes through a thread tension meter 24 of a suitable type on its way to a thread guide 23 and further to the unspecified work station of the flat knitting machine.
  • the thread 25 is guided over stationary thread guide rollers 26 and over at least one thread guide roller 27 which is movable under the thread tension.
  • the thread tension meter 24 supplies control signals dependent on the measured tension of the thread 25, with which the electric motor 22 of the automatically adjustable thread brake 20 is actuated either in one direction to increase the braking effect or in the other direction to reduce the braking effect.
