Definitions

  • the invention relates to a ring spinning machine with a ring rail, wherein on the ring rail spinning rings are arranged, on each of which a ring traveler is slidably mounted. There is a sensor for detecting the motion of a ring traveler. A separator is arranged between two adjacent spinning rings above the ring rail so that at a Ringbankhub the distance to the ring rail remains constant.
  • the EP 1 052 314 A1 discloses a sensor system for a ring spinning machine. On the ring bench spinning rings are attached. The ring traveler runs on the spinning rings. During spinning, the ring traveler is driven by the thread and set in rotation. A sensor detects the movement of the ring traveler. In this way, thread breaks can be detected. In the vicinity of the spindle, a display means is arranged, which indicates the thread breakage to the operator. The sensor is attached to the ring rail. Various sensors are described which operate according to different measuring principles. The most common method of non-contact scanning of the ring traveler motion is the use of a magnetic sensor. But it is also possible to use vibration sensors, optical sensors or acoustic sensors. Such a sensor for a ring spinning machine with acute sensors discloses the EP 0 442 327 A1 , the DE 19 66 963 A1 and the WO2004 / 015179 A1
  • inductive sensors for detecting the movement of the ring travelers are arranged separately from the ring rail via a respective holder on an axis parallel to the ring rail axis.
  • the axis can be the axis that also stores separators.
  • the separators are also referred to as balloon separators or disc separators. These are separating plates made of metal or plastic, which are arranged between two juxtaposed spindles above the ring rail. The separators prevent filament balloons of two adjacent spindles, which form during spinning, obstruct. The disturbance of the balloons by a broken at an adjacent spindle thread is avoided.
  • the DD 293 152 A5 discloses a sensor assembly with two inductive sensors for detecting the ring traveler movement of two adjacent spindles. So that the sensors can reach the respective ring rotors, the housing of the sensor assembly is arranged around the separator separating the spinning stations. This requires a corresponding complexity of the housing. The housing is fixed in a slot on the ring rail or on a machine-length cable duct.
  • the sensor is located close to the spinning ring.
  • the accessibility of the spinning ring is at least limited.
  • the accessibility of the spinning ring is required not only in an exchange of the weary spinning ring or the ring traveler, but also at each thread break. For re-spinning, the operator manually moves the ring traveler to a suitable position, for which he moves his finger along the spinning ring.
  • the object of the present invention to further improve the accessibility of the spinning ring and the ring traveler and the protection of the sensors.
  • the ring spinning machine according to the invention the features of claim 1. Due to the arrangement of the sensor on the separator, the sensor itself no longer hampers the accessibility of the spinning ring.
  • the separators are usually required to limit the thread balloon and thus anyway available. A separate holder for the sensor is eliminated.
  • the separators have a greater distance to the spinning rings than the usual inductive sensors. A certain distance of the separators is required so that a thread balloon can form.
  • the inductive sensors must be arranged close to the spinning ring due to measuring principle. In addition, the distance must be set very accurately.
  • the inductive sensors also have field-generating coils.
  • the invention is based on the finding that acoustic sensors are significantly lighter and can be arranged at a greater distance from the spinning ring.
  • the microphone does not burden the separator with its size or its weight.
  • the greater distance of the separators from the spinning rings is not a problem for acoustic sensors while providing protection to the sensor.
  • Acoustic sensors also have the advantage that they are less sensitive to variations in the distance.
  • the same arrangement can be used with spinning rings of different sizes.
  • non-magnetic ring travelers can be used.
  • the measuring arrangement according to the invention thus additionally increases the flexibility of the ring spinning machine.
  • the microphone is arranged on a board, which is embedded in a slot of the separator.
  • the board can be further equipped with evaluation for the microphone.
  • the separator When the microphone or board with the microphone is embedded in the separator, the separator also acts as a housing, protecting the sensor from contact. An arrangement of the microphone under the separator causes a contact protection.
  • a second microphone can be arranged, which detects the movement of the ring traveler of the adjacent spinning ring.
  • only every second separator has a circuit board.
  • the two microphones not only share the board, but can also transmit electronics, Use voltage supply etc. together.
  • a display means is arranged, indicating the elimination of the movement of the ring traveler. In this way, it is easy for the operator to recognize the spinning station with a thread interruption among the plurality of spinning stations of a ring spinning machine and perform the Wiederanspinnen.
  • a display means can indicate the elimination of the movement of one of the two ring travelers. That is, two spinning stations share a display means. In this way, the total number of display means of the ring spinning machine, which indicate a thread break, can be halved. For orientation for the operator, a display means for two spinning stations is absolutely sufficient. If the operator has reached the area of the display means, the workstation in need of service is easily recognizable.
  • the invention also relates to a separator for a ring spinning machine, in the lower region of which a microphone for detecting the movement of a ring traveler is arranged.
  • the microphone is held by the separator.
  • the Fig. 1 shows in a plan view a ring rail 1 of a ring spinning machine.
  • the ring rail 1 has spinning rings 2, on each of which a ring rotor 3 is rotatably mounted.
  • separators 6 are arranged above the ring rail 1 separators 6 are arranged.
  • the separators 6 are between two spinning rings 2 and between two spinning stations of the ring spinning machine arranged to limit the forming during ring spinning thread balloon and to avoid contact of the thread balloons adjacent spinning stations.
  • the separators 6 are moved in spinning operation together with the ring rail 1 up and down.
  • the separator 6 has, as in the FIGS. 1 and 2 to see a board 7 up.
  • the Fig. 2 shows the separator in side view.
  • the circuit board 7 is arranged in the lower region of the separator 6. That is, the circuit board 7 is located at the ring bank 1 facing the end of the separator 6.
  • the arrangement in the lower part of the separator 6 is due to the required proximity to the spinning ring 2.
  • the board 7 has two microphones 4 and 5, which are each arranged so that they point in the direction of a spinning ring.
  • the microphones 4, 5 detect the movement of the ring traveler 3. When the motion signal is absent, a thread break can be concluded. Since the movement of two adjacent ring rotors can be detected by means of the illustrated board, only every second separator 8 is equipped with a board 7 in the illustrated embodiment.
  • the circuit board 7 also has an evaluation unit, not shown.
  • the board 7 can be connected via terminals 10 to a power supply and to the central control unit of the ring spinning machine. Further, an LED 8 is arranged on the operator-facing side of the board, which serves as a display means.
  • the evaluation unit evaluates the signals of the two microphones 4 and 5. When the elimination of the movement of one of the two ring rotors is detected, the LED lights up and indicates a thread breakage to the operator. In the present embodiment, therefore, two spinning stations share an LED 8.
  • the board 7 is embedded in a slot of the separator 6.
  • the separator 6 thus serves at the same time as a housing for the circuit board 7 and thus protects the microphones 4 and 5.
  • a small opening is provided on the side surfaces of the separator 6 through which the sound can pass.
  • An opening for the LED 8 is provided on the front side of the separator facing the operator.
  • a transparent cover 9 is provided for the LED 8. At the opposite Side, ie on the rear side facing away from the operator, exit the terminals 10 of the board 7.
  • the inventive arrangement maintenance work on the spinning ring 2 are not hindered.
  • the ring traveler 3 can easily be exchanged or yarn breaks can be carried out without affecting the sensor 4, 5.
  • the sensor 4, 5 is protected by the separators 6.
