Definitions

  • the invention relates to a device for optimizing the regulatory settings a spinning machine with a regulated drafting system, in particular a regulating path, a card or a comber.
  • the invention also relates to a corresponding method and a Spinning machine.
  • a spinning machine with a regulated drafting system is for example the regulating section RSB-D 30 from Rieter, where the thickness fluctuations at the entrance of the incoming slivers by means of a mechanical Scanning (grooved roller / tracer roller) measured continuously and in electrical Signals is converted.
  • the measured values are an electronic Memory supplied with variable delay.
  • the corresponding measured value is determined by the electronic memory Approved. This distance between the measuring location of the pair of sensing rollers and The place of delay is called the regular point of use. When the standard point of use is reached, depending on the measured value, an adjustment action of the control motor takes place.
  • the tape test is randomly and manually determined the correct adjustment of fluctuations in thickness of the or of the slivers performed. This is the normal number submitted slivers (e.g. six slivers) stretched and at the same time regulates their fluctuations. After that, one of the submission tapes removed and the remaining tapes adjusted so that the required tape fineness (in the unit "ktex"; becomes colloquial also the term tape weight used) of the normal number of original tapes is achieved. In a further step the original becomes Number of slivers presented (in the example previously 6 ribbons) additional tape added.
  • the bands are in turn adjusted so that the tape fineness of the original number of tapes was also observed becomes.
  • the procedure and the The calculation basis is for the RSB-D 30 route from Rieter in the brief instructions under point 2.31, section 3C / 100 to 3C-102.
  • DE 42 15 682 A1 is a solution for one automatic band test described in which a transient signal such as a thick spot for carrying out a tape test online is presented.
  • this method has the particular disadvantage that in a constant control movement, the regulation parameters, in particular the control starting point and the regulation intensity, based on the measured values be influenced at the exit of the drafting system and thus also an uninterrupted and therefore not necessarily the desired control movement takes place, which causes restlessness.
  • DE 42 15 682 becomes the transient signal by temporarily supplying a reserve band generated, this method is correspondingly expensive.
  • a further complex adjustment of the regulatory parameters is necessary if the measured values of the strip mass sensor or strip thickness sensor at the drafting system inlet with a defined slow speed opposite the machine normal delivery speed (in the range of today 800-1000 m / min) in Depending on the material properties must be corrected.
  • a defined slow speed opposite the machine normal delivery speed in the range of today 800-1000 m / min
  • the deflection of the sensing roller depends on the speed is different.
  • the depth of penetration the feeler roller depends on the type of fiber, even if it has the same fineness exhibit.
  • the Rieter machine mentioned so far has been the So-called "adjustment of fiber type" carried out (see brief instructions for the above Line RSB-D 30 from Rieter under point 2.30, section 3C / 99), in which the actual belt fineness at the drafting device outlet (also outlet belt fineness called) in the slow running of the machine with the actual belt fineness is compared at normal delivery speed.
  • This will have an impact on the sliver leaving the drafting system using gravimetric Sorting checked, i.e. there will be a band rehearsal of e.g. 10 m length at normal delivery speed and afterwards Slow speed (e.g. at 1/6 of the normal delivery speed) produced.
  • the invention offers the advantage that the parameters can be optimized more quickly for regulation - especially regulation intensity - and the dynamic behavior of the regulating sections, especially when changing lots and material change is made possible. It is also possible incorrect measured values when starting the machine due to calculation quickly recognized and corrected by means of the control and / or regulating unit.
  • the necessary computing unit or the necessary microprocessor can form a separate unit or in another, for example a central processing unit in or also the sensor arrangement be integrated.
  • the normal operation of the Drafting system used.
  • non-normal operation can be extrapolated, such as large material inherent and / or machine internal Influences on regulation. If more precise corrections are desired third and fourth, etc. drafting systems can also be included in the evaluation be taken up, the operation of these operations also corresponds to a non-normal operation (the corresponding one Measuring point for normal operation was obtained in the first drafting system operation).
  • the device according to the invention and the method can be used with advantage especially when the at least one sensor is at the outlet of the drafting system delivers very high measuring accuracy.
  • Is most suitable here is an almost ideally measuring sensor that measures the strip thickness or its Measures fluctuations in the drafting system outlet with little error, for example with an error of not greater than 0.9%.
  • the regulation parameters can then be measured at the drafting system outlet for the drafting system.
  • a microwave sensor see e.g. WO 00/12974
  • a microwave sensor is called measuring the tape mass, instead of the tape thickness. Therefore, when in the context of this invention "Strip thickness" is mentioned here in the case of a microwave sensor also the term "tape mass”.
  • the Add or remove a single reference tape or one basically simulates any portion of one or more reference tapes.
  • the active (Real) adding or removing a single reference volume to the normally presented slivers can be omitted.
  • Language usage of the invention - as at least a second drafting system the presentation of one or more slivers or non-integer Sliver shares in addition to or less than the real submitted Fibers simulated.
  • the above-mentioned simulation of the tape test has the advantage that - in contrast for example to DE 42 15 682 A1 mentioned above - the actual one Band characteristic is not important. So it doesn't have to be a transient Signal used in the submission tapes or a reserve tape to perform the tape test. Instead, one is enough for everyone simulation to be carried out at any time.
  • Such a simulation advantageously involves the control drive of the drafting device are given control signals which indicate the electrical voltage the actual strip thickness fluctuations - determined from the signals of the at least one sensor arranged at the inlet - by the amount of voltage according to the simulated, added or removed Increase or decrease sliver content.
  • control signals which indicate the electrical voltage the actual strip thickness fluctuations - determined from the signals of the at least one sensor arranged at the inlet - by the amount of voltage according to the simulated, added or removed Increase or decrease sliver content.

  • the measured Actual band finenesses are now preferred with the target band finenesses iterative adjustment of the regulation intensity adjusted until the actual band fineness essentially correspond to the target tape fineness. This means that the actual tape fineness deviation is very small; how to continue is below, the actual tape fineness deviation is used as the calculation quantity used.
  • the simulated one can Band tests should be repeated accordingly until a sufficiently accurate one Agreement of actual and target values for the outlet belt fineness is present. For example, Limit values or accuracy values specified no further simulations will be carried out if the values are undershot become.
  • the characteristic of the control drive can be corrected, especially its Tilt. It should be noted that the characteristic curve also varies depending on the machine set delivery speed changed and advantageously is calculated or saved for the respective delivery speed.
  • the procedure of the simulation of the tape test should be based on an example be made more explicit.
  • the sliver thickness fluctuations m i measured by a sensor at the drafting system inlet which consist of the average sliver mass m doubling and its fluctuations ⁇ m i , are determined and converted into electrical measurement signals U i (composed of U doubling and ⁇ U i ) converted.

  • the measurement signal of the average tape mass m doubling corresponds to the so-called 0% adjustment (operating point).
  • the electrical voltage U doubling which corresponds to the average tape mass, is increased, for example, by the DC voltage amount ⁇ U + 1band , which corresponds to the addition by a sliver.
  • this increase for example, to only the maximum band thickness fluctuations that occur, for example + 10%. If six tapes were presented, the addition of one tape would mean a corresponding tape thickness fluctuation of 16.7%. With a restriction to the 10% mentioned, the presentation of a complete sliver is not simulated, but only about 10 / 16.7 of a sliver. For the sake of simplicity, however, the simulation of the addition (and removal) of an entire volume is assumed below.
  • control drive receives control signals which correspond to the voltage ⁇ U i of the actual strip thickness fluctuations plus the simulated additional DC voltage amount of ⁇ U + 1band . This results in a real dilution of the drawn fiber sliver compared to the nominal sliver fineness by a proportional amount ⁇ U + 1 sliver to the DC voltage amount.

  • the actual value of the associated A% value can then be calculated using equation (2). If this actual value is above a limit value, the regulation intensity is preferably changed and the simulated band test is preferably carried out again.
  • one or more other tape templates can be simulated, for example the removal of a tape to calculate the associated A% actual value. In principle, however, it is possible to carry out the simulation only for one situation or only for a second drafting system operation (adding or removing a sliver or sliver portion) and preferably comparing the result with that for the sliver actually presented.
  • the measurements are carried out iteratively by calculating the A actual % value for the at least two drafting systems and, if necessary, then changing the regulation intensity in order to achieve the corresponding A actual % under these new conditions. -Calculate value until it has fallen below a predetermined limit value and the corrected regulation intensity, ie the optimal setting, has been found.

  • the calculations of the actual A% values are expediently carried out in accordance with equation (2) or (4), the corresponding band finenesses, advantageously averaged over several measurements, having to be taken into account.
  • the sliver fineness is measured when simulating an additional sliver (second drafting system) and the sliver fineness is simulated when a sliver is removed (third drafting mode) and in normal operation (first drafting mode).
