Definitions

  • the invention relates to a winding unit of an automatic Winding machine, which is a splicing device for connecting the Has thread ends after a thread break, and at Liquid, especially water, in the splice connection is introduced.
  • Thread splicing device enriches, for example Injection device when splicing the splice air with water on. A small amount of liquid must be dosed very precisely, atomized and together with the dosed splice air be fed to the splice chamber.
  • a preferred application for splicing devices are for example winding units of winding machines, as in the DE 196 50 879 A1 are disclosed.
  • the level of general pollution also plays a role Winding point due to moisture released by the wet splice during of the winding process play an increasingly important role. It is therefore desirable to be able to keep the amount of splice water small.
  • the Amount of water can be controlled using facilities and procedures such as these for example in the already mentioned DE 33 37 895 C2 are described, applied in doses.
  • the security that the splice connection also decreases sufficient water for the required strength of the Wet splice and thus the yarn.
  • Used for dosing selected an amount of water that, as usual, is significantly higher than the required for sufficient strength of the yarn Amount of water is a hindrance when introducing the Water, for example due to contamination of the supply line, below the target amount of splice water cause. Even so, there will still be enough moisture in the splice connection introduced to the required To achieve strength of the yarn.
  • the object of the invention is to overcome the aforementioned disadvantages mitigate or eliminate and adequate moisture-dependent strength of splice connections too when reducing the amount of moisture to be applied to secure.
  • This task is performed by a winding unit with the characteristics of Claim 1 solved.
  • the invention overcomes both the prejudice that capacitive Sensors on threads with moistened splice connections should be avoided, as should the prejudice that the Striving for the smallest possible amount of water inevitably Losses in securing the yarn quality leads.
  • a capacitive sensor with which a change in the dielectric when passing the moistened splice connection is detectable.
  • the sensor is coupled to an evaluation unit that falls below a predefinable threshold value of the change a signal generated.
  • the generated signal preferably serves as Error signal.
  • a display means can advantageously Error message is displayed.
  • a cleaner is arranged in the thread path, and the generated Signal triggers a cleaner cut.
  • criteria for failure of the splicer to determine and saved. There are the generated signals with the criteria compared and if the criteria are met, a fault signal generated.
  • Means for cleaning components are advantageous Splicing device available, and if there is one Malfunction signal is a component cleaning and a subsequent repetition of the splice connection activated. With switching off the winding unit if there is a Interference signal, the generation of more faulty Splice connections avoided.
  • the dielectric is used for Pass the splice connection only in the area of the Splice connection detects and does not go into one continuous mass determination of the thread. In this way incorrect evaluations, especially regarding the Avoid mass of thread.
  • an optical sensor available in addition to capacitive sensor.
  • the capacitive sensor also takes advantage outside of the Area of the splice connections measurements on the thread.
  • an optical sensor in addition to capacitive sensor is the determination of the density of the thread and thus further yarn parameters can be carried out.
  • a sensor can carry out sole continuous thread check if the other Sensor is temporarily used for other purposes.
  • the number of measurable yarn parameters and the safety of the Measurements increased significantly.
  • Another backup of the Yarn quality advantageously serves as a means of recording statistical data on the overall coil quality as well as a Monitoring system for displaying the results.
  • the threshold is less than the target quantity. The difference between the target quantity and the threshold value must be at least that for sufficient strength of the splice connection correspond to the required amount of water.
  • the invention allows in a simple manner, which is characterized by a Reduction in the number of spliced joints Benefits of a low amount of moisture Amount of moisture or the reduction of disadvantages due to too much moisture in the To use splice connections without endangering safety, sufficient durability of the thread and a desired one To achieve yarn quality.
  • the running thread 1 first passes through one Balloon limiter 4 and a thread tensioning device 5.
  • the thread 1 then runs through a Thread cutting device 6, a splicing device 7, one Cleaner 8 and a guide eye 9.
  • the drive drum 10 drives the cheese 3 over during the winding process Friction on.
  • a motor 11 gives the drive drum 10 the Rotary motion.
  • the cleaner 8 has a capacitive sensor 13 and is connected to the evaluation device 12 via a line 14 connected.
  • the control device 15 is via line 16 with the motor 11, via line 17 with the evaluation device 12 and thus via the Evaluation device 12 with the cleaner 8, via the line 18 with the splicer 7, via line 19 with a Actuating device 20 and via line 21 with the Thread cutting device 6 connected.
  • Via line 22 is the control device with a data processing system 23 connected, the means of collecting statistical data on the overall package quality as well as a monitoring system Showing results.
  • the line 28 serves the Data transfer with other control devices, Data storage or evaluation and the control of other elements of the winding unit or Dishwasher.
  • a splice connection 24 generated by the splicing device 7 is with a precisely dosed small amount of liquid acted upon and then passes through the capacitive Sensor 13 of the cleaner 8.
  • the moisture in the Splice connection 24 generated measured value is despite the small Amount of liquid is still much larger than that by the mass of the thread 1 generated measured value.
  • Thread 1 By means of one in itself known length measurement of the wound on the package 3 Thread 1 is the time of passage of the Splice connection 24 predetermined by the sensor 13 and a targeted measurement of the dielectric in a die Splice connection 24 comprising predetermined section 29 of the Thread 1 performed.
  • the thread mass outside the splice 24 then the total mass of the Splice connection 24 itself and to the splice connection 24 subsequent thread mass measured capacitively.
  • the humidity in the feed connection 24 leads to a clear Rise and fall of the measured value.
  • FIG. 2 shows the measured values as a curve over a time axis.
  • the curve 35 runs at a low level, produced by the thread mass outside the splice connection 24, with the measured value D M 31.
  • the curve 35 exceeds the threshold value D SW 32 and has reached their maximum with the measured value D max 34, the amount of moisture represented by the measured value D max 34 being slightly above the desired value D set 33 for the amount of moisture to be introduced.
  • the measured value D max 34 can, for example, be 40 times the value D M 31.
  • curve 35 has fallen back to the measured value D M 31. This is the condition for a sufficient amount of moisture D SW ⁇ D Max Fulfills. No error signal is generated.
  • the evaluation can alternatively also be carried out in such a way that the area 40 enclosed by the curve 35 and the value D M 31 hatched in FIG. 2 is used as a measure of the change occurring due to the moisture content of the splice connection 24 and compared with a corresponding threshold value becomes. In this case too, a signal is triggered when the corresponding threshold value is undershot.
  • FIG. 3 shows a change caused by the amount of moisture in the splice connection 24, the value D T 37 of which does not reach the target value D target 33 and also falls below the predetermined threshold value D SW 32. So that is D SW > D T and the condition for a sufficient amount of moisture D SW ⁇ D T not fulfilled. If the threshold value D SW 32 is undershot, a signal is generated. The generated signal serves as an error signal and can be displayed as an error message via a display means, for example via the monitor of the data processing system 23.
  • Thread cutting device 6 controlled and a cleaner cut triggered. Then there is again between the thread ends a splice connection 24 is established, which also the Sensor 13 passes through and is checked. Kick two or several successive repetitions of the splicing process on, is reached from reaching a predetermined number of Repetitions on lack of functionality of the Splicer 7 closed.
  • FIG. 1 An exceeding of a further predetermined threshold value D SWO 38 by the measured value D Ü 39 of the change is shown in FIG.
  • the measured value D Ü 39 of the change exceeds both the threshold value D SW 32 and the target value D Soll 33 without triggering a signal.
  • Exceeding the threshold value D SWO 38 by the measured value D Ü 39 of the change generates a signal which serves as an error signal. So that is D Ü > D SWO and the condition that applies to the limitation of a permissible amount of moisture in the splice connection 24 in addition to the condition D SW ⁇ D T mentioned above D Ü ⁇ D SWO not fulfilled.
  • Inadequate splice connections 24 can be caused by various Errors or malfunctions. Will one Splice connection 24 recognized as faulty, the fault Example may be caused by a compressed air line in the splicer 7 is clogged. About the Control device 15 and line 19 is the Actuator 20 controlled and the metering valve 26 so set that via the compressed air line 26 from a Air source not shown with air compared to Operating pressure increased pressure of the splicer 7 supplied and blowing out with the aim of making any to loosen and remove existing dirt. Alternatively or additionally, cleaning the Water supply line carried out by means of increased pressure become. Generates the subsequent repetition of the Again a defective splice connection 24, it is concluded that there is an error that cannot be corrected automatically, the winding unit is stopped and an interference signal is generated and displayed.
  • the disorder can also be caused by this, for example caused that the water supply of the Splicer 7 is exhausted because the filling of the Water supply is disabled or interrupted.
  • the cleaner 8 has an optical sensor 27. This considerably increases the possibilities of the measurement and increases the reliability of the measurement results and the evaluations by comparing the measured values. If the cleaner 8 also takes measurements on the thread 1 outside the area of the splice connections 24, data about the entire bobbin travel can thus be recorded, statistically evaluated and the results can be displayed via a monitoring system. The value corresponding to the measured value D M 31 for the detected mass of the thread 1 outside the area of the splice connections 24 is shown in dashed lines in FIGS. 2 to 4 as the average value.
