Definitions
- the invention relates to methods and apparatus for determining the bobbin circumference of cross-wound bobbins on a textile machine producing cross-wound bobbins and for evaluating the result, in which measured values which are produced by the growth of the cross-wound bobbin and which are evaluated appropriately are used to determine the extent of the cross-wound bobbin or the length of thread wound on the package is closed.
- a “diameter adjustment” is known on automatic winding machines, which enables the user to produce bobbins with certain final diameters.
- the requirements for this facility are: - Exact measuring method of the bobbin diameter at the respective winding point, - measurement method independent of winding parameters, - Good reproducibility of the diameter setting.
- a simple way to measure the diameter of a package is to measure the frame angle.
- the coil diameter can then be calculated using the cosine theorem, since the frame geometry remains the same.
- This measuring method also has the advantage of being independent of winding parameters.
- Another possibility for determining the coil diameter is to measure the period duration ratio of a coil revolution to a drive drum revolution. With the additional condition that the circumferential speeds of drum and spool are the same, this ratio multiplied by the drum diameter gives the current spool diameter.
- the procedure is inaccurate and it is dependent on the set winding parameters, e.g. B. thread tension, weight, drum type, etc., depending.
- the invention has for its object to improve the quality of the package production.
- this object is achieved in that the measured values representing the growth of the package are continuously recorded and in at least one computer for further The evaluation is processed and, if necessary, saved so that when further evaluation is carried out for each winding position, based on their measurement data, a mathematical link symbolizing the current winding circumference, which has been cleared of the randomness of the current measured value recording, is repeated again and again at very short time intervals, so that the current winding circumference or winding radius is derived from this link or bobbin diameter is calculated and that the linking result is used with the least possible delay for the purpose of displaying, influencing the winding process, determining the thread length and / or for ending the winding process.
- the invention is based on the following findings:
- a cylindrical drive drum drives a conical coil by friction
- the friction ratio between the drum and the coil results in a speed ratio which relates to the driven diameter of the conical coil.
- the circumferential speed of the coil is smaller towards the small diameter and greater than the circumferential speed of the drum towards the larger coil diameter.
- V Tr Peripheral speed drum
- V Sp Peripheral speed coil
- r Sp Coil radius (neutral zone)
- r Tr Drum radius
- ⁇ Sp Coil angular velocity
- Tr Drum angular velocity
- T Sp Spool period
- Tr Drum period
- the driven diameter of the package can be determined.
- the driven diameter depends on the thread tension, i.e. on the bobbin running time (seasonal fluctuations), on the spool taper and on the weight of the spool.
- the position of the driven diameter on the coil is relatively constant during the entire coil running time.
- the first phenomenon depends on the taper of the coil. It is therefore less important for the repeatability of the measurement method.
- the second phenomenon is responsible for the repeatability of the measurement method. What is striking is the wide range with a low spool force. Thread tension fluctuations during a cop run time have a strong impact. This bandwidth reduces the repeatability of the process.
- the coil diameter can be calculated using both mathematical equations.
- the parameters to be determined for the respective coil are identical in both formulas, namely d0 and ⁇ .
- a mathematical compensation method is required, which sets d0 and ⁇ so that the sum of the error squares of the measured diameter value is minimal compared to the pre-calculated diameter value. This can be done with the help of a mathematical filter, for example a Kalman filter.
- the filters are used to determine the values of the two parameters d OK and ⁇ K , which parameterize the theoretical coil diameter profile. With the values of these parameters, however, no winding process control, for example a diameter adjustment, is possible.
- the spool period T Sp of the cross-wound bobbin and the drum period T Tr of the drive drum are measured continuously.
- the diameter d Sp of the cross-wound bobbin is determined at precisely defined intervals according to Formula 1, A. Since the number of revolutions of the coil, B, or the coil running time, C, are known from the measurement of the coil period, each can be calculated using the mathematical method Compensation method determine the values of the parameters d OK and ⁇ K.
- the mathematical equalization methods require the mathematical filters that can be developed from Formula 2, D, and Formula 3, E.
- the diameter can be calculated using formulas 2 and 3, so that a new diameter value d m is present after each measurement. The increase in the coil diameter during the coil travel can thus be measured.
- the coil circumference can only be determined fuzzy within a more or less wide range.
- the influence on the winding process, the display, the determination of the thread length or the detection of the bobbin diameter which is decisive for ending the winding process or the thread length which is decisive for ending the winding process is correspondingly imprecise.
- the invention now ensures that a bobbin circumference cleaned from the coincidences of the winding process can be determined with a significantly smaller inaccuracy bandwidth, so that the influence on the winding process can be made with much greater accuracy and with more precise reproducibility, so that a total Quality increase of the package production can be achieved.
- the measured values representing the growth of the package are continuously recorded and processed in at least one winding unit computer assigned to the individual winding units of the textile machine for further evaluation, that the further evaluation may be carried out in a higher-level computer connected to the winding unit computer or units is that, if necessary, in the higher-level computer for each winding station, based on their measurement data, a new mathematical link symbolizing the current bobbin circumference, which has been cleared of randomness of the current measured value recording, is carried out again and again at very short time intervals, that the current bobbin circumference or bobbin radius or bobbin diameter is calculated from this linkage and that the linking result, if necessary, again to the winding station computer for the purpose of displaying, influencing the winding process, determining tion of the thread length and / or for the purpose of ending the winding process is transmitted with as little delay as possible.
- the measured values of a sensor detecting the angle of rotation of the drive drum are advantageously linked to the measured values of a sensor detecting the angle of rotation of the cross-wound bobbin, in order to infer the result of the linking of the circumference of the cross-wound bobbin, in the computer or in Superordinate computer from these continuously new connection results again and again the mathematical connection effecting the elimination of the randomness of the current measured value recording is formed or the compensation function is calculated.
- selected measured values of the winding travel or their linking results are used to calculate the compensation function.
- Those measured values or their linking results which are obtained from a selectable point in time of the winding travel are advantageously used for calculating the compensation function.
- a specific period of time can also be selected and this period of time can extend, for example, to a period of time which, calculated from the respective measurement point in time, always points to the past at the same time interval.
- the compensation function is calculated using mathematical filters.
- a filter of the Kalman filter type is advantageously used as the mathematical filter.
- the compensation function is represented as a polynomial.
- the angular velocities of the drive drum and the cheese are measured and linked and stored in one of the computers before the compensation function is calculated from the link results.
- a higher-level computer takes over the calculation of the compensation function and the compensation function in turn symbolizes the measurement result that has been cleaned of randomness.
- the signals, possibly transmitted back from the higher-level computer, representing the current bobbin circumference or bobbin radius or bobbin diameter are combined in the computer or in the bobbin station computer with the signals representing the angle of rotation of the cross-wound bobbin and the angle of rotation of the drive drum in order to derive the current wound thread length and / or calculate the current winding density, display it if necessary and compare it with setpoints, intervening in the winding process if necessary on the basis of the comparison result.
- the course of a winding trip can be saved as a setpoint.
- the winding density of the package can be influenced, for example, by varying the thread tension and the package can be adjusted, for example, either to a constant winding density or to a winding density that changes continuously in the course of the winding phase. If tolerances are exceeded, the winding process can be interrupted because the cheese no longer meets the quality requirements.
- the method is provided in a further development of the invention that the sensors are connected to at least one computer that prepares the measured values for further evaluation, that a link program for a mathematical linkage of the prepared measured values symbolized by the randomness of the current measured value recording and symbolizing the current coil size is entered into the computer, and that the computer has devices for displaying the linking result and / or devices for influencing the winding process in accordance with the linking result and / or devices for determining the thread length in accordance with the linking result and / or Has facilities for ending the winding process in accordance with the linking result.
- the link result can be shown on a display, for example.
- the winding process can be ended, for example, when the desired thread length is reached or when the desired current bobbin circumference is reached. With conical The current coil size is in the so-called neutral zone.
- the sensors are connected to at least one winding station computer that prepares the measured values for further evaluation, that the winding station computer is connected via a first operative connection to a higher-level computer to which a link program for a mathematical link that cleans the randomness of the current measured value recording and symbolizes the current bobbin size the measured values prepared by the winding station computer are input that the higher-level computer has a second operative connection for transmitting the linking result to the winding station computer d that the winding unit computer has devices for displaying the linking result and / or devices for influencing the winding process in accordance with the linking result and / or devices for determining the thread length in accordance with the linking result and
- the linking program is set up for calculating a mathematical compensation function symbolizing the current coil size, which has been cleaned of randomnesses of the current measured value recording, over the winding time.
