  • devices have proven to be very suitable for a fast and positionally precise thread switching whose parallel to the axis of rotation of the cheese displaceable yarn guide is connected via a traction means with a reversible single drive or facilities that work with a so-called finger thread guide or wiper, that is, yarn guide, which have a finger-like thread-laying lever which is pivotable about a substantially perpendicular to the cheese axis arranged axis over a certain angular range.
  • a workstation of a cheese-producing textile machine in which a rotatably held in a creel sleeve by a drive roller having a separate drive, can be rotated.
  • the job also has a traversing yarn guide, which is fixed to an endless belt and can be guided back and forth by a defined controllable single drive within a changeable in its length traverse stroke.
  • the single drive of the traversing yarn guide is coupled with an angle encoder, which detects the rotor position of the electric motor and reports to a controller.
  • the WO 00/24663 describes a Fadenchangier adopted with a finger thread guide, the drive to a sensor device, a so-called rotary encoder is connected, which monitors the movement of the finger thread guide. It is stated in this patent application that in order to check the system state and if necessary to correct the rotary encoder, it is occasionally returned to a reference point.
  • the Faden enteringarm can also be brought into contact with a mechanical stop, wherein the corresponding output signal of the encoder is evaluated to give a reference for the positioning.
  • the Fadenchangier worn is designed as a finger thread guide, which is acted upon by an electromagnetic drive.
  • the electromagnetic drive of the thread guide drive is controlled by a microprocessor, which controls the current strength and the current direction according to a predetermined program angle and time-dependent that results on the Traversierbreite the respectively desired laying angle of the thread or that set the traverse width or the traversing points targeted can be.
  • an infrared light barrier is used, which scans marks arranged coaxially to the oscillating axis.
  • such optical sensor devices are not entirely unproblematic due to the known in spinners and winders often heavily loaded with dust and fluff air. That is, such optical sensor devices require to work largely trouble-free, a relatively high cleaning costs.
  • the post-published DE 103 54 587 describes a job of a cheese-producing textile machine, which has a creel for holding a rotatable package and a finger thread guide for traversing a supplied thread has.
  • the electromotive single drive of the finger thread guide is equipped with an angle sensor which is connected to a workstation computer and has a pivotally mounted permanent magnet and a stationary Hall IC element.
  • Such an angle sensor has several advantages.
  • the relatively inexpensive analog Hall IC element which is influenced by the magnetic flux of a pivotally mounted permanent magnet, generates, for example, voltage values which are proportional to the angular position of the permanent magnets and thus to the angular position of the finger thread guide and which can be well processed by the workstation computer.
  • the winding head module in this case has a single-motor driven coil drive roller and also a single-motor driven Fadenchangier affection.
  • the Fadenchangier noticed equipped with a finger thread guide is equipped with an angle sensor, which is designed as a Hall effect sensor.
  • the Hall effect sensor which detects the passage of the finger thread guide through the center of the thread-passing area, is protected within a plastic housing.
  • the present invention seeks to develop a method and a device that allows the proper operation of a job of a cheese-producing textile machine over a longer period.
  • a measured value is generated by the sensor element in these defined positions.
  • the determined measured values are compared in the workstation computer and / or processed to calculate a correction characteristic of the sensor element.
  • the correction characteristic curve calculated by the workstation calculator characterizes the measured value curve of the electrical voltage that the sensor element generates at this time when the thread guide oscillates between its reversal points.
  • the workstation computer assigns during the winding process according to the correction characteristic of each voltage generated by the sensor element to the associated position of the thread guide, which is then used to control the thread guide.
  • the determined correction characteristic as set forth in claim 3, at least until the next adjustment use. This means that during the next adjustment, the correction characteristic curve is recalculated by the workstation computer based on the measured values then available and, if the calculation results, replaced by a new correction characteristic curve.
  • the apparatus for performing the method according to the invention in an advantageous embodiment, acted upon by a single drive Fadenchangier worn, equipped with a Hall IC element angle sensor and a workstation on.
  • the angle sensor supplies in each case a measured value proportional to the position of a thread guide.
  • means are provided which allow positioning of the thread guide in defined positions.
  • the workstation computer is designed so that it immediately associates each electrical voltage generated by the Hall IC element of the angle sensor with an associated position of the yarn guide. In this way, the workstation computer is able to optimally control the thread guide, in particular as regards its reversal points.
  • the thread guide as described in claim 6, designed as a finger thread guide
  • the thread-laying lever is positioned by applying two stops each in defined angular positions.
  • a measured value generated by the Hall IC element of the angle sensor is detected in these so-called adjustment positions and used in the workstation computer for calculating a correction characteristic curve of the angle sensor.

  • Such a generous dimensioning of the area which can be covered by calibration ensures that the installation tolerances occurring, for example, during assembly of the thread guide drive can be reliably compensated for.
  • the positioning of defined stops at + 39 ° and -39 ° also makes it possible in a simple way to balance the measured values provided by the angle sensor with known angular positions of the thread-laying lever of the thread guide.
  • the angle sensor has a resolution of 0.024 ° (claim 8). Such a high resolution of the angle sensor allows a precise approach of the thread reversal points in the thread switching and thus a homogeneous coil structure.
