Definitions

  • the present invention relates to a method for correcting a characteristic dependent on the strip thickness of a sliver characteristic in the region of a textile fiber structure stretching the fiber structure, wherein the characteristic is determined continuously or at intervals during the stretching of the sliver. Furthermore, a textile machine with a device for stretching a sliver and a control and / or regulating unit will be described.
  • EP-A-0,574,693 A2 shows a known prior art.
  • band weight ie the mass per sliver length
  • the determined values are finally graphically displayed and / or serve as the basis for the regulation of the drafting system of the textile machine.
  • the textile machine In order to be able to detect the weight of the band, the textile machine generally has corresponding mechanical sensors (eg in the form of so-called pulleys whose distance from each other depends on the band thickness). The sensors in turn provide measured values which are detected by the control and / or regulating unit and further processed accordingly.
  • the object of the present invention is now to propose a method and a textile machine which permit an improved correction of a characteristic quantity representing the strip thickness of the fiber band in comparison with the prior art.
  • the method for the correction of a characteristic dependent on the strip thickness of a sliver characteristic in the range of a Fiber structure-stretching textile machine characterized in that the determined after a stoppage of the textile machine amounts of the characteristic are at least temporarily corrected depending on the deviation of the determined after standstill characteristic of a defined before standstill reference value.
  • the correction of the determined parameter does not occur as a function of corresponding temperature values. Rather, the actual measurement error that can be observed after a longer standstill is used as the basis for the correction of the parameter.
  • this measurement error is high, ie, the amount of the parameter determined after the standstill of the textile machine differs greatly from the reference value recorded before the standstill, this is a sign of a strong cooling of the sensor or sensors during the standstill period.
  • the determined after standstill amount of the parameter must be corrected accordingly strong.
  • only a relatively small correction is necessary if the parameter determined after the standstill deviates only slightly from the reference value, which represents the amount of the parameter which was determined before the standstill.
  • the invention is based on the following basic idea: During the operation of the textile machine, ie during the stretching of the sliver, a parameter is detected continuously or at predetermined time intervals which depends on the strip thickness of the drawn sliver.
  • This parameter is the measuring signal of the sensor measuring the strip thickness, the band weight calculated on the basis of these measuring signals, or else the absolute or relative deviation of corresponding values from a nominal value. If the textile machine comes to a standstill, it gradually cools down. This leads to incorrect measurements after a restart, since the elements involved in the measurement increase only slowly and at different speeds to their operating temperature. The amounts of the parameter will therefore deviate after the standstill from the amounts measured shortly before standstill, even if the room temperature and have not changed the sliver thickness during the standstill of the textile machine.
  • the amounts of the parameter measured after standstill are corrected by a value which is dependent on the standstill-related deviation of the measured after standstill characteristic of the measured before standstill amounts.
  • the amounts measured before the standstill are taken into account here by the reference value mentioned, which will be discussed in more detail in the course of the description.
  • the corrected amount of the monitored parameter (measurement signal, band weight, deviation of the band weight from a target value, etc.) corresponds to the true amount.
  • the reference value corresponds to the last determined before standstill amount of the parameter or the average value of a defined number of determined before standstill amounts of the parameter.
  • the last measured value measured or the amount of the monitored parameter calculated therefrom is stored in a corresponding memory of the textile machine. If there is a scheduled or malfunction-related shutdown of the textile machine, so there is always a value available, which can be used as a reference value after the resumption of drafting operation. This is based on the finding that the strip thickness remains unchanged during a standstill of the textile machine. When resuming the operation of the same, therefore, the amount of the monitored characteristic should agree with the amount measured before standstill. This value is therefore particularly suitable to serve as a reference value.
  • the amounts of the parameter determined after standstill are increased, at least for a defined period, if the amount of the parameter determined immediately after standstill is below the reference value, or if the amounts of the parameter determined after standstill are at least for one be reduced if the amount of the immediately after standstill parameter is above the reference value.
  • the amounts of the parameter determined after standstill in this case are corrected in such a way that they are as close as possible to the true value, ie. H. the value determined prior to standstill.
  • a correction of the value determined after standstill will take place downward.
  • the reason for this is the fact that the components of the thickness of the sliver monitoring sensor contract during the standstill due to temperature. The distances become larger, so that the sensor detects too high a sliver thickness. If the corresponding measured value or the characteristic derived therefrom is now corrected downwards after the standstill, the actual amount is again obtained with a correspondingly strong correction.
  • the invention provides that the amount by which the parameter is corrected after the textile machine is at a standstill, starting from an initial value continuously or stepwise, preferably in the form of an exponential function, is reduced.
  • This takes into account the fact that the individual components of the textile machine gradually warm up to their operating temperature after re-operation.
  • the temperature-related, or in other words standstill-related, measurement errors are therefore always lower with increasing operation, with the reduction can usually be represented by an exponential function.
  • the reduction can in this case continuously or else stepwise, the amount by which the parameter is corrected being always reduced in the last-mentioned case after a predetermined period of time.
  • the characteristic variable is always corrected by the same amount over a certain period, the amount being reduced from time to time until no correction is made at the end.
  • the time duration of the individual time periods is lengthened from time to time.
  • the initial value by which the parameter is corrected after the textile machine is at a standstill is the difference between the amount of the parameter determined immediately after standstill and the reference value or the difference between the average of several of the amounts determined immediately after standstill corresponds to the parameters and the reference value.
  • the corrected parameter immediately after standstill, the corrected parameter essentially assumes the amount which existed before standstill.
  • temperature or standstill measurement errors that can be observed for a certain period of time after a standstill, completely eliminated.
  • the parameter before standstill has an amount X which also serves as a reference value and an amount Y when restarting the stretching operation, this results in a corrected amount, which results when the difference between X and Y is subtracted from the amount Y becomes.
  • the correction of the parameter takes place only after a predetermined period of time after the textile machine has come to a standstill, the period preferably after each standstill and in particular as a function of the temperature in the region of one or more components of the textile machine (eg of the textile machine) Drafting system) is recalculated.
  • test series can be carried out from which it can be seen after which period a previously stopped textile machine or its sensor monitoring the strip thickness again has its operating temperature. If this time has elapsed after the resumption of the stretching operation, so the correction of the characteristic can be terminated, since it can now be assumed that no standstill measurement errors are present.
  • the stated period can be defined as an absolute value or recalculated depending on the actual downtime after each standstill. In this case, a short stoppage phase also entails only a relatively short correction phase.
  • the period during which the parameter is corrected is subdivided into a plurality of time windows, wherein the amount by which the parameter is corrected is constant within a time window and at the same time less than in the respective preceding time window.
  • the reduction of the correction amount is thus stepped (as already indicated above), wherein the individual time window can always be the same length or can also include a decreasing or increasing time duration.
  • the length of the period during which the parameter is corrected depends on the difference between the parameter determined immediately after standstill and the reference value. If the difference is relatively large, this means a large measuring error, which is due to a long standstill and thus cooling phase of the textile machine is due. In this case, a longer correction phase is necessary because the sensors require a corresponding amount of time to heat up to their operating temperature. On the other hand, if the difference is relatively small, this indicates a short downtime. The determined parameters must therefore be corrected due to the lower cooling of the relevant measuring elements only for a relatively short period of time.
  • the parameter is corrected by a continuous or stepwise reduced amount after stopping the textile machine until a previously defined sliver length or sliver mass has passed the textile machine.
  • the stated values are easy to monitor and allow a conclusion on the possible rewarming of the textile machine after a standstill.
  • a correction of the characteristic from a certain sliver length no longer makes sense, since it may have come in the meantime to fluctuations of the sliver thickness and therefore the parameter does not necessarily have to accept the reference value.
  • the parameter is corrected by the standstill of the textile machine as long as a continuously or gradually reduced amount until the temperature measured at a defined point of the textile machine the determined immediately before standstill amount having. At this point in time, it can finally be assumed that the monitored parameter is no longer subject to standstill-related incorrect measurements.
  • the parameter it is of course also conceivable to correct the parameter until the said temperature assumes a defined maximum value.
  • This maximum value can correspond, for example, to the maximum operating temperature of the textile machine.
  • the location of the temperature measurement should be selected such that the measured values are representative of the temperature of the sensor which monitors the sliver thickness.
  • a corresponding temperature sensor should therefore preferably be arranged in the region of the temperature-sensitive elements of the sensor system. With appropriate calibration, however, other parts of the textile machine are conceivable.
  • the characteristic quantity is corrected by a continuously or stepwise reduced amount after the textile machine has stopped until one or more parameters of the textile machine, for example the drafting ratio of a drafting system of the textile machine, are manually or with the aid of a control and / or Control unit to be changed. In this case, it will automatically come to a change in the monitored characteristic, since as a parameter preferably a size is used, which depends on the thickness of the sliver. The correction of the parameter depending on the reference value is finally no longer meaningful and is therefore aborted.
  • a correction takes place only when the downtime is at least 30 minutes.
  • the correction of the parameter takes place after a standstill of the textile machine only if the difference between the reference value and the absolute value of the parameter determined immediately after standstill or the mean value of several values of the parameter determined immediately after standstill Exceeds limit.
  • This development is based on the fact that, if the deviation is too small, it can not be ascertained with final certainty whether the difference is due to temperature fluctuations or to an actual fluctuation of the fiber sliver thickness.
  • the monitored parameter is the relative deviation (A%) of the band weight of the sliver from a nominal value. In this case, a correction only makes sense if the deviation (A%) after standstill differs by at least one to two percentage points from the deviation (A% ref.) Stored as the reference value.
  • the correction of the parameter takes place after a standstill of the textile machine only when the difference between the measured at a defined point of the textile machine before and after standstill temperature exceeds a defined limit (for example, 10 ° C).
  • a defined limit for example, 10 ° C.
  • the temperature directly indicates whether there has been any significant cooling during the standstill, which ultimately results in an influence on the sensor monitoring the strip thickness and thus in corresponding measurement errors.
  • the textile machine according to the invention is finally distinguished by the fact that its control and / or regulating unit is designed, one dependent on the strip thickness of a sliver and determined in the area of the textile machine Correct characteristic according to previous description.
  • control and / or regulating unit is designed, one dependent on the strip thickness of a sliver and determined in the area of the textile machine Correct characteristic according to previous description.
  • FIG. 1 schematically shows a Regulierumble as an example of a textile machine according to the invention in side view.
  • a sliver 2 is removed from each of a plurality of so-called supply cans 1 and fed to the respective drafting system 3 of the route.
  • the drafting system 3 is usually made of three or more pairs of rollers 4, each comprising a lower roller and a top roller and cause by different speeds a delay and thus a homogenization of the sliver 2.
  • the stretched sliver 2 is finally supplied with the aid of a Kalanderwalzenpases 5 a rotating storage tray 6 and stored by this looped into an empty pot 7.
  • a sensor In order to monitor said equalization during the stretching process, a sensor, not shown, is preferably arranged in the region of the drafting system or of the calender roller pair, which monitors the fiber sliver thickness.
  • sensors have scanning elements whose accuracy or their measured values depend on the temperature of the respective components.
  • a typical temperature profile show the FIGS. 2 to 4 , Wherein the course before the standstill with the reference numeral 11 and the course during the standstill is provided with the reference numeral 12.
  • the temperature (measured at a selected point of the textile machine, for example in the region of the sensor) until the beginning of the standstill (time t 1 ) is almost constant. If the movable components of the textile machine finally stand still, the temperature gradually decreases until the time t 4 , at which the drawing process is resumed (the temperature profile between the times t 2 and t 3 is not shown for reasons of clarity). From the time t 4 , finally, there is again an increase in the measured temperature (see the temperature characteristic indicated by the reference numeral 13), which finally reaches the value that it had before the standstill at time t 8 .
  • the figures given also show the time profile of the amount of the monitored parameter (in the example shown, the parameter is the percentage deviation of the band weight from a nominal value, but alternatively the sensor transmitted by the sensor could also be used Measured value, the resulting calculated tape thickness, tape mass or other depending on the distortion of the sliver 2 sizes monitored or graphed).
  • the sensor From the time the textile machine (t 4 ) is restarted, the sensor finally returns measured values which, due to the cooling of the textile machine and thus also of the sensor, are correspondingly faulty.
  • the deviation of the band weight calculated from the measured value from a desired value (A%) stored in the control and / or regulating unit at the time t 4 is significantly above the value determined before the standstill, although the strip thickness has not changed during the standstill (Finally, the sliver 2 was not transported during standstill).
  • a standstill or temperature-related measurement error is recorded, which is reflected in the difference between the amounts of the parameters at the times t 1 and t 4 .
  • either the absolute value of the characteristic quantity recorded immediately before the textile machine stops or else the mean value of a series of corresponding amounts can be defined as reference value 14.
  • the amount of the parameter determined immediately after standstill is compared with the reference value 14. If the last-mentioned amount is greater than the reference value 14 by an amount X, then this is a sign that the cooling of the individual components during the standstill at the time t 4 results in a measurement error that results in the value increased by the amount X. Characteristic results.
  • the invention now proposes subtracting from the value ascertained at time t 4 the measurement error-related amount, ie the difference between the characteristic variable and the reference value 14. Finally, at time t 4 , a corrected parameter is obtained whose magnitude corresponds to the reference value 14. Finally, the procedure is analogous with the amounts of the parameter determined after the time t 4 , whereby the amount by which the characteristic is corrected (reduced in the example shown) is continuously reduced (resulting in the value determined in FIG Figures 3 and 4 shown curve with the reference numeral 10). This reduction of the correction amount takes into account the fact that the measurement errors with increasing temperature increase of the textile machine or the sensor are always lower.
  • the amount by which the parameter is corrected can be based on this calculated from the amount determined at time t 4 . It thus makes sense to reduce the correction amount on the basis of an exponential function on the basis of the difference between the ascertained parameter and the reference value 14 at the time t 4 . As a result, one obtains a corrected course of the monitored parameter whose course is in principle the curve 10 provided with reference numeral 10 FIG. 3 corresponds (the fluctuations within the curve are not due to measurement errors, but due to the variation of the sliver thickness and require no further correction).
  • the time period over which the correction takes place can be determined experimentally.
  • the temperature can be determined at a representative point of the textile machine and the time can be measured until the measured temperature has increased again to the operating temperature after a complete cooling of the textile machine causing standstill. This time corresponds to the time in which a correction of the characteristic makes sense, since the measurement errors after this period are no longer due to the cooling of the textile machine during standstill.
  • FIG. 4 shows in that it is sufficient to detect the parameter or the temperature at specific time intervals, so that the step-shaped curve profiles result. It is also possible to gradually reduce the amount by which the characteristic is corrected.
  • the correction amount in the example is FIG. 4 within the individual time window (t 4 to t 5 , t 5 to t 6 , t 6 to t 7 , t 7 to t 8 ) are each constant, so that the sawtooth-like course of the corrected characteristic results (reference numeral 10).
  • FIG. 4 to take a further advantageous embodiment of the invention.
  • a correction of the characteristic usually makes sense only after a prolonged machine downtime, as it is after only a short downtime (eg shutdown phases with a length of less than 30 minutes), no significant and corresponding measurement errors ensue cooling of the relevant components. It can therefore be provided to make the correction according to the invention only when the downtime has exceeded a certain limit.
  • the method described is of course also applicable if it comes during the correction phase to a new standstill of the textile machine.
  • one or more of the above-mentioned parameters are used as a basis for deciding whether the correction should be continued, terminated or restarted.
  • advance correction value can be stored in the control and / or regulating unit.
  • This value can be calculated, for example, from the length of the downtime and serves as the basis for the correction of the parameter immediately after standstill. This can be of great advantage if the first determination of the parameter takes place only after a certain period of time after the restart of the textile machine. In this case, by the deposit of the advance correction value always an initial value available, so that immediately after restarting the textile machine with the correction of the characteristic can be started.
  • the control and / or regulating unit determining the preliminary correction value can be designed to be self-learning, whereby the actually determined or calculated correction values are stored as advance correction values for later standstills with comparable standstill times and used accordingly.
