  • the ring spinning machine further comprises a guide device with a first and a second guide means for raising and lowering the ring rail.
  • the first guide means is fixedly arranged on the ring spinning machine and the second guide means is connected to the ring rail and moves when lifting and lowering the ring rail relative to the first guide means.
  • the present invention also relates to a method of operating the sensor.
  • the EP 1 052 314 A1 discloses a generic ring spinning machine.
  • the ring spinning machine has a ring rail, which is moved up and down during the spinning process.
  • a holder for guide rods is attached, which vertically movably guides the ring rail.
  • the movement of the ring rail allows the filament to be deposited on the spinning cop.

  • Each workstation or spindle is assigned a spinning ring.
  • Each spider ring is associated with a sensor for monitoring the thread of each job. Such sensors detect the movement of the thread along the spinning ring.
  • the movement of the thread itself is detected to monitor the thread.
  • the ring traveler is carried along by the thread and guides the thread along the spinning ring.
  • the movement of the thread or of the ring traveler can be detected, for example, by means of vibration sensors, optical sensors, acoustic sensors or magnetic sensors. If the sensors no longer detect movement, a thread break can be concluded. A corresponding signal from the sensor is forwarded to a higher-level control of the ring spinning machine. This then initiates an interruption of the Vorgarnzucht at the relevant job. It is also possible, To detect the speed of the ring traveler and thus close to the spindle speed.
  • the signals from the sensors are forwarded to a higher-level control or evaluation unit.
  • the sensors must be supplied with electrical energy.

  • the modulation of the alternating field can be done for example by field weakening.
  • the longer guide means may be formed as a rod and the shorter guide means as the sleeve surrounding the rod. It is possible to arrange the rod stationary on the ring spinning machine and to connect the sleeve with the ring rail. The sleeve is then moved along the bar as the ring rail is raised and lowered. Alternatively, it is possible to arrange the sleeve stationary on the ring spinning machine and to connect the rod with the ring rail. When lifting and lowering the ring rail then moves the rod in the sleeve.
  • the coil which is arranged on the rod, formed as a cylindrical coil and arranged concentrically about the axis of the rod.
  • the turns of the cylindrical coil can then be wound around the lateral surface of the rod.
