Definitions

  • the invention relates to a thread tension sensor, in particular for supplying elastic threads to knitting machines Thread delivery device for knitting machines and a method for Adjusting a thread tension sensor.
  • Thread delivery device for elastic yarns known for Use on flat knitting machines.
  • the Thread delivery device is used to supply elastane threads and has a thread delivery wheel driven by an electric motor on.
  • the electric motor is controlled by a control loop controlled with the current thread tension a thread tension sensor detected.
  • This has one pin that can be deflected transversely to the thread running direction, over which the thread is guided at an obtuse angle. The deflection of the pin corresponds to the thread tension and is detected by a suitable displacement sensor.
  • DE 39 42 341 A1 describes a force sensor for Monitoring thread tension known in the case of a Sensor element is mounted on a spring parallelogram.
  • the deflection of the sensor element is based on a a flexible body provided with variable resistance transmitted so that the deflection of the sensor element and thus the thread tension is electrically detectable.
  • the constant tension is particularly important when supplying elastic threads for the production of elastic knitted fabrics of great importance. Even the slightest fluctuations and especially propose long-term changes itself in a changing or changing Quality. Therefore, the thread tension also applies over long periods, i.e. Hours, days and months to keep stable away.
  • Knitting machines and thread delivery devices are becoming common used in workshops in which, not least due to the heat loss of the knitting machines, the temperature throughout the day and according to the duration that changes machines. This also changes Temperatures of the thread tension sensors, what despite possibly existing temperature compensation influences whose output signal can have. They can also be long term Dirt deposits for a change in the sensor output signal cause, for example, deposits the total weight on a pin to record the thread tension of the pen and thus the zero point shift the signal.
  • Thread tension sensor to create a long-term stable Detection of the thread tension enables. Furthermore a thread delivery device is to be created that the Thread with a flat knitting machine, for example constant thread tension. After all it is Object of the invention, a method for operating a To create thread tension sensor when using it the sensor has a reliable long-term stable output signal delivers.
  • This task is done with a thread tension sensor with the features of claim 1, with a thread delivery device with the features of claim 17 and a method according to claim 22 solved.
  • the thread tension sensor according to the invention has except for its thread sensing element, which is used to measure thread tension is in contact with the thread, a thread take-up means on that is movably mounted. At least it points two different positions on each other differ in that the thread is in a calibration position is separated from the thread sensing element and in the Measuring position of the thread take-up means on the thread sensing element is present. It is therefore through targeted adjustment of the thread take-up means and / or the thread tension sensor possible, the thread arbitrarily from the thread sensing element take off so that it comes to its rest position. This is characterized by the fact that no force acts on the thread sensing element. The measuring device detects this position or state of the thread sensing element.
  • the thread tension sensor has drifted, can this when lifting the thread from the thread sensing element recognized and recorded. For example, that Lifting the thread from the thread sensing element for zero adjustment of the thread tension sensor can be used. On this way, long-term offsets can be avoided, otherwise the output signal of the thread tension sensor would overlay.
  • offset influences for example by temperature drift or by deposits on the Thread sensing element could be caused in the long run generates a sensor output signal that is the thread tension reproduces zero-point errors. This enables the construction of a thread delivery device with high Long-term constant thread tension.
  • Thread take-up means the thread to the thread sensing element; for calibrating it leaves the thread from the thread sensing element take off.
  • Thread take-up means remove the thread from the thread sensing element path; for measuring it leaves the thread on the thread sensing element issue.
  • the calibration or zero point adjustment process is preferably carried out when the thread delivery device provides no thread. During this period by zeroing induced or permitted thread tension fluctuations cannot interfere here of the knitwear produced. Alternatively it is possible to adjust the zero point with a short time Lifting the thread from the thread sensing element, if the thread moves slowly or his Movement speed currently does not change. In this Fall is the control device regulating the thread delivery briefly hidden, i.e. their output signal will be on the current value is clamped, the zero point adjustment carried out and after replacing the thread on the The thread loop sensor is activated again.
  • the calibration process is then carried out when it is allowed (released) and (as a second criterion) when requested.
  • This is usually regular Time intervals the case.
  • the time intervals can be shorter after switching on the machine (2 min.) and longer after running in (30 min.).
  • the thread tension sensor preferably has one Drive device assigned to thread take-up means, for example a pull magnet or another Drive (electric or pneumatic rotary, swivel or Linear drive) on by a calibration device can be activated and the thread take-up means drives such that this in its first thread of the thread-sensing element is transferred to the lifting position. Now the zero point adjustment can be carried out. Becomes If the drive device is deactivated, the thread take-up means arrives in its second position, in which the thread abuts the thread sensing element. Preferably that is Thread take-up means in this position from the thread separated, i.e. does not touch it. This will Measurement error due to friction of the thread on the thread take-up means eliminated.

In the simplest case, these are pens that to the preferably also pin-shaped Extend the thread sensing element in parallel. It can eyelets can also be used. Both the pin of the thread sensing element as well as the pins of the thread take-up means extend transversely to the thread running direction, preferably at right angles to this. This ensures that even with relatively wide pens all thread positions are equal on the pen, so that the thread does not saw in a preferred location.
  • the thread sensing element of the thread tension sensor is preferably mounted on a spring parallelogram.
  • the preferably pin-shaped thread sensing element is then in arranged at right angles to the spiral springs. Thereby one-sided clamping and storage of the Thread sensing element and it is a good measurement accuracy ensured.

Once this is done the calibration circuit deactivates the drive device, so that the thread is back on the thread sensing element is launched.
