Definitions

  • the subject of this invention is the image or mirror disturbance (hereinafter referred to as "mirror disturbance") when winding threads in a wild winding.
  • the double stroke is the sum of two successive strokes, that is to say a forward movement and a return movement, and the double stroke number is the number of double strokes per unit of time. Do the speed of the spindle per unit of time and the number of double strokes depend on each other e.g. due to a gear connection between spindle and traversing drive, a precision cross winding is created.
  • this invention deals with all types of winding in which the speed of the spindle is not constantly dependent on the double stroke rate (wild cross winding, wild winding), in particular those cross windings which are in accordance with DIN 61 801 by a constant ratio between the double stroke number and the Mark the circumferential speed of the coil. Wild cross windings in the narrower sense of DIN 61 801 are especially produced when winding up man-made fibers that are produced at a constant high speed after being created or processed.
  • the circumferential speed of the coil is obtained by tangential drive (drive by means of a drive roller which is driven at a constant speed and abuts the circumference of the coil) or by measuring and regulating the circumferential speed of the coil.
  • the traversing speed i.e. the double stroke rate is constant (DIN 61 801) or is changed slightly, but in any case without a fixed relationship to the speed of the spindle. This has the consequence that in the course of the bobbin build-up (winding travel) the winding factor, i.e. the ratio of spindle speed to traversing speed decreases hyperbolically as the coil diameter becomes thicker.
  • the winding factor i.e. the ratio of spindle speed to traversing speed decreases hyperbolically as the coil diameter becomes thicker.
  • mirrors In the area of these mirrors, the thread pieces of several successive layers of turns lie directly one above the other. In particular, this creates the danger that the pieces of thread lying on top of one another will slip laterally and thereby jam each other. Mirrors therefore impair the running properties of the bobbins, in that they lead to thread breaks or possibly make the bobbin unusable. However, mirrors also lead to the centric and axial asymmetry of the bobbins and thus to asymmetrically distributed bobbin hardness, bobbin density and mass distribution, when using drive rollers to asymmetrical contact pressure, to vibrations during the winding process and to damage to sensitive thread material.
  • a mirror is created in the areas of the winding travel in which the winding factor, i.e. the quotient of spindle speed and double stroke number is an integer.
  • Intermediate mirrors occur when the coil factor deviates from an integer coil factor by a fraction with a small denominator, in particular 1/2, 1/3.
  • Coil factors in which mirrors or intermediate mirrors occur are referred to in the following in the same way as mirror values or mirrors.
  • Higher order mirrors are those with a higher mirror value. It is known to cause a mirror disturbance in that the number of double strokes is changed periodically or aperiodically within predetermined narrow limits. Here, however, it is inevitable that when the winding factor approaches a mirror value, in particular an integer mirror value, this mirror value is run through several times and with a certain dwell time. This type of mirror disturbance therefore does not eliminate the passing through of the mirror values, but only eliminates or alleviates the symptoms of the respective mirror (cf. e.g. US-A 3235191 6 CH-A 416406).
  • JP-A 41 060 it is also known in such a method that a certain safety distance should always be maintained between the mirror value and the approaching winding factor, the safety distance resulting in particular from the thickness and the sliding properties of the thread.
  • the periodic or non-periodic change (wobble) of the traversing speed by an average value is known per se for the purpose of mirror disturbance (cf. CH-A 416406).
  • the wobbling of the initial value of the traversing speed makes it unnecessary for certain mirrors or intermediate mirrors with only minor mirror symptoms to switch over to the disturbance value of the traversing speed, or the switchover can take place with a reduced safety distance.
  • the disturbance value of the traversing speed is wobbled, mirror symptoms that occur in the intermediate mirror area of the disturbance value of the traversing speed can be avoided or defused.
  • the wobble can also take place in the area of integer mirrors, in particular in the area of integer mirrors of higher order. However, it is preferably applicable in the area of intermediate mirrors and in particular lower-order intermediate mirrors.
  • the combination of the mirror disturbance according to the invention by skipping mirror values and by changes in the initial value and / or changes in the starting value and / or the disturbance value of the traversing speed allows fault-free coils to be achieved for the first time, which can be determined, on the one hand, by their volume, on the other hand, by a large ratio of Diameter to stroke, due to faultless yarn quality, especially uniformity and uniform dyeability, excellent run-off properties even when the thread is pulled off the bobbin at high take-off speeds of e.g. More than 1000 m / min, mark thread take-off overhead without thread breakage and without thread tension fluctuations and also for threads with unfavorable winding properties such as Hosiery yarn or threads with a low single capillary titer are suitable.
  • the safety distance of the winding factor from the mirror values is measured from the mean value of the winding factor, which results from the mean wobbled traversing speed (initial value or disturbance value).
  • This safety distance is determined according to the regulations of this invention. It is preferably greater than the amplitude of the winding factor, which results from the wobble of the traversing speed. This means that even the extreme values of the winding factor, which result from the wobble of the traversing speed, should not get into a mirror or intermediate mirror. It is even provided and preferred that the extreme values of the winding factor also maintain a safety distance, which, however, can be specified relatively small, since the extreme values of this winding factor are only passed through for a short time.
  • This minimum safety distance is the smallest permissible difference between the winding factor and an adjacent mirror or intermediate mirror.
  • the minimum safety distance must be observed both from the winding factor, which results from the initial value of the traversing speed, and from the winding factor, which results from the disturbance value of the Traversing speed results. If the winding factor reaches or approaches this minimum safety distance from a mirror value, the traversing speed is switched over and thus the winding factor changes.
  • the minimum safety distance according to this invention is
  • the safety distance and the minimum safety distance are preferably defined as a certain fraction p of the mirror value to be avoided or the winding factor, which is the quotient of the current measurement of the spindle speed and the traversing speed (double stroke number).
  • the practical difference lies only in the structure of the electronic control required in each case, for which a person skilled in the art has suitable means available in both cases.
  • the resulting difference in the safety distance according to the calculation methods shown is very small and can be neglected in terms of textile technology.
  • the fraction p is preferably constant over several successive mirrors. However, it can also be varied if experience has shown that mirror symptoms, particularly in the case of low-order mirrors, can be expected relatively early before the mirror value is reached.
  • the order of magnitude p is less than 5% and generally more than 0.1%.
  • the fraction p is to be determined by experiments or - what is still to be discussed - from the textile data of the winding process.
  • the minimum safety distance is the safety distance, which must not be undercut, in particular if the winding factor approaches a mirror value or intermediate mirror value in the course of the winding travel. In this case the mirror risk is greater and the mirror symptoms are more serious than in the case in which the winding factor moves away from the mirror value or intermediate mirror value as the winding travel progresses.
  • the safety distance S and the minimum safety distance can - as already stated - be determined on the basis of experience.
  • the invention provides that the safety distance S is proportional to the mirror value and the smallest permitted thread spacing of adjacent threads of two successive turns, measured from thread center to thread center on the surface line of the bobbin, and inversely proportional to the double stroke (double stroke).
  • the mirror order but above all the thread quality is taken into account.
  • the thread deposited on the bobbin also spreads across its axis.
  • the double stroke rate is relatively large.
  • Low-order mirrors in particular, are therefore particularly harmful. Under certain circumstances, these mirrors distribute unevenly on the bobbin due to the short bobbin length, so that there is an axially and / or radially asymmetrical mass distribution of the thread on the bobbin and destruction of the bobbin at high thread speeds. This is avoided by the inversely proportional dependence of the safety distance on the coil length according to the invention. It can be seen that the factor p shown in connection with claim 1 corresponds to the size A / 2H explained here.
  • the thread spacing A can also be replaced by the width B of the thread deposited on the bobbin, measured on the surface line of the bobbin, that is to say taking the filing angle into account, so that the factor p is B / 2H. If the resulting minimum safety distance is undershot, there will be mirror symptoms in any case.
  • This dependency of the jump height on the safety distance and minimum safety distance is also largely responsible for avoiding mirror symptoms.
  • the traversing speed is switched so that there is a sudden change in the winding factor.
  • This change of The winding factor is so large that the changed winding factor is also outside the safety range.
  • the safety area is the area of those coil factors that does not maintain the minimum safety distance from a mirror value or an intermediate mirror value on the positive side or on the negative side. This means that the jump height of the winding factor is at least twice the minimum safety distance.
  • the method identified in this way is based on the finding that the risk of mirror symptoms also occurring is at a distance in front of and behind each mirror value and depends on the mirror order and on the jump height caused by the change in the traversing speed, ie the change in the jump height of the winding factor.
  • the specified safety distance is limited to the minimum safety distance. Rather, a larger safety distance can also be specified.
  • the jump height of the winding factor which is brought about by changing the traversing speed, should be equal to or greater than twice the specified safety distance.
  • S1 the safety distance of the winding factor when approaching a mirror value
  • S2 the safety distance of the winding factor after switching the traversing speed
  • the disturbance value of the traversing speed is only maintained for a certain time.
  • the change in the traversing speed from the disturbance value to the initial value and the change in the winding factor to be effected in this way occurs in any case when the spindle speed has dropped to such an extent that the safety distance between the avoided mirror value and the winding factor is again given, which is the quotient the spindle speed and the initial value of the traversing speed (output coil factor).
  • the traversing speed can be increased or decreased from its initial value NCA.
  • the NCS disturbance value of the traversing speed is therefore either greater or smaller than the initial value NCA.
  • the output value and disturbance value are preferably kept constant over the entire winding cycle, or at least over a substantial part of the winding cycle, in particular when a plurality of winding units have the traversing drive in common.
  • the traversing speed is lowered from the next mirror value when the winding factor enters the safety distance, the winding factor increases and the reaching of the mirror value is initially postponed. If the spindle speed has now dropped so far that the winding factor, which results from the disturbance value of the traversing speed (disturbance winding factor), has reached the specified safety distance, the traversing speed must be increased again to its initial value, which means that the winding factor must be lowered again and the mirror value must be run through . It is also important that this is done in the shortest possible time.
  • the switchover can also take place beforehand, at the earliest when the spindle speed has dropped so far that the output coil factor has the specified safety distance from it Mirror level reached. If the ratio Q is greater than two and a second or higher order deceleration is to be expected when the traversing speed is increased, the switchover must take place beforehand, when the spindle speed has dropped so far that the output spool factor has the specified minimum safety distance reached and exceeded the mirror value again.
  • the winding factor is reduced.
  • the mirror value is run through quickly. This is achieved in the following way: If the increase in the traversing speed occurs with a delay of the first order, the safety distance becomes as small as possible, i.e. is specified as the minimum safety distance, but the ratio Q is chosen to be greater than 2. This ensures that the safety area of the mirror is passed through with great acceleration.
  • the increased disturbance value of the traversing speed is maintained until the spindle speed has dropped so far that the output spool factor has again reached the safety distance from the mirror value. Because of the limited size of this delay of the traversing speed for technical reasons, the switchover can also be a little earlier, but it can also be done later.
  • Increasing the traversing speed for the purpose of the mirror disturbance has the advantage that an impairment of the coil structure is avoided or there is less fear.
  • By increasing the traversing speed the actual The filing stroke of the thread turns on the bobbin is reduced. This eliminates the risk of thread pieces slipping out of the end faces of the bobbin as a result of an excessively large stroke (stripper). This type of mirror disorder is therefore preferred.
  • the initial value NCA of the traversing speed is determined according to the desired coil structure, in particular according to the desired crossing angle.
  • the crossing angle when winding synthetic fiber smooth yarn in spinning or stretching machines in its order of magnitude at 5 to 12 °, preferably at 6 to 9 °.
  • the decisive factor here is the quality of the coil structure.
  • the traversing speed expressed as a double stroke number, then results from the specified thread speed and the specified bobbin length or stroke length.
  • the change DC of the traversing speed is then within the scope of this invention between 0.1 and 5%, preferably between 1 and 5%, of the initial value NCA of the previously determined traversing speed.
  • the change in the traversing speed is also limited in that the switching of the traversing speed to the fault value and the maintenance of the fault value over a period of time do not allow an adjacent mirror value or intermediate mirror value of harmful effects or their safety range to be reached.
  • the amplitude of the wobble is preferably matched to the minimum safety distance.
  • the safety distance according to this invention should therefore in any case be greater than the amplitude of the coil factor in the mirror region, this amplitude being calculated according to the formula Fx a / 1 + a or - which is approximately the same - FSPxa / 1 + a.
  • the extreme values of the wobble preferably maintain a minimum safety distance.
  • the safety distance is greater than the sum of the minimum safety distance FSPx Pmin plus the amplitude of the coil factor in the mirror area, the minimum distance of the extreme values of the coil factor from mirror values being designated as Z and preferably being equal to FSPxB / 2H.
  • the wobble may also offer Perceptible possibility to approach the mirror values even more with the extreme values of the winding factor.
  • the mean value of the traversing speed which is decisive for the determination of the switching times, is determined when the wobble is superimposed, preferably by measurement and also by integrating the continuously measured wobble values.
  • the relative amplitude is preferably identical for the initial value NCA and the disturbance value NCS of the traversing speed.
  • the breathing movement of the traversing device and the wobble movements can be coordinated with one another in a known manner with additionally superimposed breathing (stroke reduction) in such a way that the resulting thread speed remains essentially constant.
  • Embodiments of the invention in which a mirror disturbance due to a jump in the winding factor and wobbling of the traversing speed are superimposed, are described with reference to FIGS. 1 to 3.
  • a fourth-order mirror is created when the four-fold mean value of the initial value of the traversing speed is equal to the spindle speed.
  • the hyperbolic line describes the spindle speed NS as a function of the winding travel (time).
  • Mirror values are shown as the integer multiple of the initial value of the traversing speed NCA.
  • the switchover to the disturbance value of the traversing speed takes place, when the mean value of the output value NCA m reaches the safety distance S 'from the spindle speed.
  • S ' is so large that there is still a minimum safety distance Z' between the extreme values of four times the traversing speed and the spindle speed.
  • Z ' is therefore preferably equal to the minimum safety distance S' min in the sense of this invention.
  • the factor Q is greater than 2.
  • Q is the ratio of the step height of the winding factor / safety distance.
  • FIG. 1 shows that the disturbance value of the traversing speed is smaller than the initial value.
  • the factor Q 2.
  • the switchover time and wobble should be coordinated with one another in such a way that the direction of change in the traversing speed always coincides with the sweep direction, as is shown in FIGS. 1 and 2 .
  • the switchover also takes place in the phase of the wobble in which the traversing speed is increased. This applies in particular if the change in the traversing speed traverses a mirror area, as in the case of switching from the initial value to the fault value in FIG. 1 and when switching back from the fault value to the output value in FIG. 2.
