  • the tension produced in the bobbin material in this way has to be compensated by the engine of the drive of the winding spindle during the winding process.
  • the torque being transmitted to the winding spindle by the engine of the drive does not depend from the control tension of the motor and from the number of rotations corresponding to the motor diagram.
  • a torque control is used in the known machine.
  • the number of rotations of the winding spindle is independent from the velocity of the arriving bobbin material and from the diameter of the material being wound up on the winding spindle.

  • the dancer arm device is used to determine a signal which is proportional to the tension in the bobbin material.
  • the bobbin material has to contact and surround a plurality of deflection rollers at least at partially substantial surrounding angles. Consequently, the bobbin material is subjected to substantial bending loads and also to changing bending loads in combination with respective friction forces. Especially in case of sensitive bobbin material being used, the bobbin material may be harmed or even destroyed.
  • An apparatus for measuring the tension of moving yarn is known from German Patent No. 29 05 713 C2.
  • the known apparatus includes fixed yarn guiding devices which ensure a straight movement of the yarn.

  • the winding machine includes a winding spindle being designed and arranged to be rotated by a drive.
  • a unit serves to determine a signal which is approximately proportional to the tension of the bobbin material.
  • the unit includes an arm being designed and arranged to be movable to a limited extent and only one roller being arranged at the arm. The only one roller is designed and arranged to guide the bobbin material to contact the feeding apparatus and the roller without contacting other elements in between.
  • the present invention also relates to a winding machine for winding up bobbin material arriving from a plurality of feeding apparatuses.
  • the winding machine includes a plurality of winding spindles each being designed and arranged to be rotated by a drive.
  • a plurality of traversing apparatuses each are designed and arranged to cooperate with one of the winding spindles to wind up the bobbin material.
  • a plurality of units each serves to determine a signal which is approximately proportional to the tension of the bobbin material.
  • Each of the units includes an arm being designed and arranged to be movable to a limited extent and only one roller being arranged at the arm. The only one roller is designed and arranged to guide the bobbin material to contact the respective feeding apparatus and the respective roller without contacting other elements in between.
  • the novel winding machine or winding apparatus includes only one roller instead of three deflection rollers as known in the prior art.
  • this one single roller With this one single roller, the tension in the bobbin material is determined by the movement of the roller. In this way, a signal is produced which has an influence on the engine of the drive driving the winding spindle by the control unit.
  • This one single roller is supported on a movable arm or a bar. Especially, the arm is supported to be pivotable or bendable. The movement of the arm is limited to a small range which is substantially less than the one during the movement of a dancer arm as know in the prior art. The one single roller will still be surrounded by the bobbin material.
  • the two stationary deflection rollers known in the prior art are not needed in the novel winding machine. Their functions are fulfilled by different elements.
  • the one single roller is arranged adjacent to the end of the feeding apparatus and the traversing apparatus. This means that no further deflection rollers are located between these two aforementioned elements.
  • the tension in the bobbin material is produced between the two deflection rollers.
  • the tension in the bobbin material is produced between the one single roller and the winding spindle.
  • the tension in the bobbin material is no longer produced by a dancer arm, but by the drive of the winding spindle.
  • the engine or the motor of the drive of the winding spindle does not only compensate changes concerning the tension in the bobbin material, but it determines the tension in the bobbin material.
  • the bobbin material moves on from the one single roller directly into the traversing apparatus. In this way, the traversing triangle is advantageously increased.
  • the unit or the device for determining a signal which is approximately proportional to the tension in the bobbin material only needs to include a comparatively small number of components, it is compact and it may be produced at low costs. Without having to use additional mechanical components, as for example deflection rollers, it is possible to produce different characteristics of tension curves during a winding travel.
  • the reason for this effect is the fact that the tension of the yarn or of a different bobbin material is only produced by the motor of the drive of the winding spindle.
  • reducing, increasing or constant tension values may be used in the form of software tables. These values may be easily and reproducibly used.
  • the movement of the one single roller being arranged at the free end of the arm preferably has a value of less than approximately 1 mm. Preferably, the value may only be approximately a few ⁇ fraction (1/10) ⁇ mm. Consequently, the surrounding angle of the bobbin material at the one single roller does not substantially change, and the geometry of the arriving bobbin material remains substantially constant during the entire winding travel.
  • the arm may include a bending bar and the unit may include at least one sensor for sensing deflection of the bending bar.
  • the arm may also be directly designed as a bending bar in a way that the arm is only supported at one side and the bending forces are applied by the bobbin material moving over the one single roller.
  • the arm only functions as a lever arm and that it is operatively connected to a bending bar which is bent by the lever arm. In this way, it is possible to intentionally enlarge the lever arm in case of respective structural conditions.
  • the bending bar includes a sensor for sensing the deflection. The sensor may be directly arranged on the bending bar, or it may be operatively connected to the bending bar.
  • the senor may include extensometer strips. However, force sensors, way sensors and the like may also be used.
  • the respective sensor may include an electronic unit with which the deflection is transformed to an electric signal, especially to an electric potential. The combination of the sensor and the electronic unit for evaluation purposes allows for a small, compact design.
  • the arm may also be designed and arranged as a scale beam, and the unit may include at least one sensor for sensing the force of the bobbin material which subjects the one roller.
  • the scale beam may also be designed as a control lever. It has a substantially stiff design, and it is supported approximately in its middle portion or outside its middle portion to transmit the force being applied onto the one single roller by the bobbin material to the sensor.
  • the sensor may include extensometer strips, force sensors or the like.
  • the preferred embodiment of the arm is the one with a bending bar including extensometer strips. It is possible without problems to fix the bending bar at its one end at the supporting structure of the winding machine, to arrange the extensometer strips approximately in the middle portion of the arm and to arrange the one roller at the free end of the arm. It makes sense to arrange the extensometer strips on the bending bar in association with the bending plane of the bending bar.
  • the bending bar may have a nominal bending portion, and the extensometer strips may be arranged in the nominal bending portion.
  • a nominal or desired bending portion may be designed as a weakened portion of the bending bar to improve elastic bending deformation at the place where the extensometer strips are arranged.
