Definitions

  • the invention relates to a method and a device for influencing the Thread braking force one between a yarn supply system and one Thread store of a weft brake arranged in a loom, according to the preamble of claim 1.
  • the weft thread is drawn off from a fixedly arranged yarn supply system which, for example, comprises one or more yarn supply bobbins. Due to the high take-off speed during the weft insertion in rapier and rifle shooter looms and due to the non-positive weft insertion in air and water jet looms, thread stores, also referred to as pre-winding devices, are used, the required thread length being deducted from a reserve thread which is located on a drum of the thread store , The thread length then results from the number of windings drawn off and the drum diameter. In the case of elastic yarns, the winding tension of the thread on the drum can influence the thread length to be entered in the shed more or less.
  • the running behavior of the yarn from a yarn supply spool is variable.
  • the thread tension at a given take-off speed is lower with a full bobbin than with a bobbin with a low thread supply.
  • unregulated thread brake systems are currently used, which are set to "brake" so strongly that the thread tension generated thereby is higher than the maximum natural thread tension that occurs when the thread is taken off the spool of thread.
  • Yarn weak points are created that lead to thread breaks when the weft is inserted. Many weavers try to work without a break-in brake. The weft yarn is treated more gently. However, the yarn length has fluctuations that increase the yarn length drop.
  • the object of the invention is that by the deduction of the yarn bobbin and mechanical use caused by thread braking systems Strain on the weft thread in the area between the yarn supply spool and to reduce the thread storage and the winding tension in Keep thread store essentially constant so that yarn waste is low to keep.
  • Thread tension can be regulated.
  • Spool overflow sensor changes from empty to full when the spool overflows Supply reel switched to adjustable infeed braking. Subsequently the control takes over its task for the fine adjustment of the braking force.
  • any type of thread brake that can vary in braking force can be used be used.
  • a leaf spring brake or a Wrapping brake used.
  • a weft thread 4 is made by one Yarn supply spool 2 of a yarn supply system withdrawn and over a Weft brake 5 and 16 guided to a thread store 11, on the Drum 12 wound up a thread length required for the weft insertion is before it through an entry member 13 in the loom of the loom is introduced.
  • the aim is to have the winding tension on the drum 12 to keep the thread store 11 as constant as possible in order to maintain a constant one Ensure the entry length of the weft thread 4.
  • this is achieved in that the thread tension of the Weft 4 in front of the thread store 11 with the help of a Thread tension sensor 10 is measured.
  • the measurement signals are electronically forwarded to a control device 14, which is preferably is part of the weaving machine control.
  • the control device the measured actual thread tension is compared with a target thread tension. If the actual thread tension deviates from the nominal thread tension, the Control device 14 outputs a signal which is used for regulation or Correction of the braking force of the weft brake 5 or 16 is used until the target thread tension is set.
  • Corresponding setpoint specifications and others, including the one used Yarn-dependent setting parameters can be made by the weaver via an input unit 15 are entered, which are part of a higher-level input unit of the Loom can be.
  • the weft brake is designed as a leaf spring brake 5 and comprises a fixed brake part 6 and one designed as a leaf spring movable brake part 7.
  • the weft 4 is between the stationary brake part 6 and the movable brake part 7 passed.
  • a motor 9 and an eccentric 8 the Contact force of the movable brake part 7 on the fixed brake part 6 can be set, whereby the braking force on the Weft 4 changed.
  • FIG. 2 shows a belt brake 16 Weft brake.
  • This comprises a disc-shaped, fixed one Brake part 17 and a disc-shaped, movable brake part 18, both are connected to each other via an axis.
  • the weft 4 is each passed through an eyelet on the edge of the disk-like parts 17, 18.
  • the movable disc part 18 can be compared to the fixed part 17 are rotated, whereby the weft 4 more or is less wrapped around the connecting axis, so that the Braking force on the weft 4 changed.
