Definitions

  • the present invention relates to a method for positioning a maintenance trolley of a ring spinning machine, a ring spinning machine and a computer program product according to the independent claims.
  • a device for the automatic repair of yarn breaks which comprises a driveable with several different speeds car.
  • a spinning machine with a treatment trolley having on each spindle a Garn adaptationswagen-detecting means which is actuated by at least three control means, which are arranged one behind the other on a side surface of the Garnbehand Vietnameseswagens opposite to a series of detection means formed on the frame to the current position and determine the direction of movement of the carriage, wherein the carriage is moved, delayed and stopped on the basis of position indicating signals of the detection means.
  • Object of the present invention is to improve the positioning of the maintenance trolley to remedy a yarn breakage of a ring spinning machine.
  • Object of the present invention is further to provide a method and an apparatus that allow a quick and accurate shutdown of the maintenance car to remedy a yarn breakage of a ring spinning machine.
  • the distance of the maintenance trolley to the spindle is advantageously measured with at least one inductive sensor with the spindle as a reference.
  • the service trolley can be positioned in a simple way centered at the smallest distance of the inductive sensor in a maintenance position to the spindle, wherein the smallest distance is determined as an absolute distance value or by deriving a distance from the inductive sensor distance curve. If the derivative is zero, the maintenance trolley is centered in front of the spindle. The central positioning is important for the correct alignment of the maintenance trolley.
  • the maintenance trolley For exact and centered positioning of the maintenance trolley, this is operated with at least two and preferably with three speeds, which follow one after the other in stages. There is a higher speed for coarse positioning of the maintenance trolley in front of a spindle. If the maintenance trolley knows the spinning position with the thread breakage, it will move to this position at this increased speed. In the section in front of the spindle, the service trolley is moved at a smaller pre-positioning speed for approaching a spindle. In the last section, the maintenance trolley is centered at a microposition speed in front of the spindle. In an alternative embodiment, the speed of the maintenance cart is continuously reduced from the higher speed to the coarse positioning of the maintenance cart in the form of a ramp to the microposition speed. In both ways, it is advantageously possible to position the maintenance trolley precisely centered in front of the spindle.
  • the maintenance trolley is equipped with an evaluation electronics for measuring the distance to the spindle, which evaluates signals from the sensors to determine the smallest distance absolute or by deriving a distance curve or calculate.
  • the evaluation electronics are also there to count the number of spindles and to determine the position of the maintenance trolley as the maintenance trolley moves by.
  • a ring spinning machine which is equipped with a corresponding maintenance trolley, wherein the service trolley is equipped with at least one inductive sensor for measuring the distance to the spindle, wherein the spindle serves as a reference.
  • a computer program product which can be loaded directly into an internal memory of a maintenance trolley and includes software code sections with which the method steps of the method according to the invention are carried out when the product is running on the maintenance trolley.
  • Fig. 1 schematically shows an inventive ring spinning machine 1, which has a plurality of juxtaposed spinning units 2.
  • the spinning units 2 are arranged in a longitudinal direction x of the ring spinning machine 1 between a head 3 1 and a foot 3 second Head 3 1 and foot 3 2 of the ring spinning machine 1 may include bearings, drives, control, etc., which are necessary for the operation of the machine.
  • each spinning station 2 consists of a roving bobbin 4, which is arranged above a drafting system 5, and on which a roving 6 is wound.
  • the roving 6 runs from the roving bobbin 4 via the drafting device 5, where it is stretched to then be guided to a Garn Strukturelement.
  • a circumferential ring winds the finished yarn on a Kops 7.
  • the cop 7 is placed on a spindle 8.
  • a maintenance carriage 9 moves, which moves in the event of a thread break to a corresponding spinning station 1 and automatically fixes the yarn breakage.
  • Fig. 2 shows the principle of positioning the maintenance trolley 9 in front of a spindle 8.
  • the direction of movement 13 of the maintenance trolley 1 along the ring spinning machine 1 is indicated by an arrow.
  • the maintenance cart 9 is equipped with a sensor 10.
  • the sensor 10 includes in the example shown in a common housing three inductive sensors 11. However, it is within the scope of the invention possible to operate the sensor 10 with two or a plurality of inductive sensors 11.
  • an evaluation unit 12 is provided for evaluation of the measurement signal.
  • the evaluation unit 12 can, as shown, be located in the maintenance carriage 9 or directly in the housing of the sensor 10 together with the inductive sensors 11 (not shown).
  • Each inductive sensor 11 has a coil which generates a magnetic field. The arrangement is chosen so that the magnetic fields overlap. This means that as soon as one of the outer sensors 11 detects a metallic object, this object can be positioned in the detection area of the central sensor 11.
  • the invention provides to measure the change in the distance to the spindle 8 with the inductive sensors 11.
  • the measuring signal reaches its peak, the maintenance trolley 9 is exactly in the center of the spindle 8. This is necessary to remedy the thread break, there is the maintenance position.
  • Fig. 3 shows the recorded by the sensor distance curve of an inductive sensor 11 to a spindle. 8
  • the maintenance trolley 9 can be operated with at least two and preferably three speeds, which follow each other stepwise. There is a higher speed for coarse positioning of the maintenance cart 9 in front of a spindle. If the service trolley 9 knows the spinning position with the thread breakage, it will move to this position at this increased speed. In the section in front of the spindle 8, the maintenance trolley 9 with a smaller Pre-positioning speed for approaching the spindle 8 moves. In the last section, the service trolley 9 is positioned centered at a microposition speed in front of the spindle. In an alternative embodiment, the speed of the service cart 9 is continuously reduced from the higher speed to the coarse positioning of the maintenance cart 9 in the form of a ramp to the microposition speed. In both ways, it is advantageously possible to position the maintenance trolley 9 precisely centered in front of the spindle 8.
  • the position of the service trolley 9 can be continuously detected.
  • the evaluation electronics 12 can determine the position on the ring spinning machine 1 by counting how many spindles 8 have already been passed.
  • the exact center of the spindle 8 can be found. This must be ensured before removing the thread breakage.
  • the invention also relates to a computer program product which can be loaded directly into an internal memory of a service trolley 9 and comprises software code sections with which the method steps of the method according to the invention are carried out when the product is running on the service trolley.
