Definitions

  • the invention relates to the method for winding threads, in particular freshly spun or drawn chemical threads into cylindrical cross-wound bobbins in step-precision winding.
  • step precision winding is known from Japanese Patent 50-65628. It is intended to determine the switching times so that the winding tension remains within certain limits. At the beginning of the winding cycle, however, the traversing speed drops very quickly in proportion to the spindle speed, since the diameter of the coil increases very quickly. The result of this is that the switching times at which the traversing speed has to be switched from the lower limit back to its upper limit follow each other very quickly.
  • the traversing frequency and the number of double strokes in this application denote the number of traversing cycles per unit of time, each traversing cycle consisting of a back and forth movement.
  • the object of the invention is to improve the winding process, in particular for chemical threads, in such a way that the circuit complexity, in particular the electronic complexity, is reduced and that a good bobbin structure is nevertheless ensured.
  • step precision winding which is known, for example, from US Pat. No. 4,049,211 and Japanese OS 50-65628, is suitable for avoiding the so-called mirror formation.
  • the solution is achieved in that the areas of the winding travel, in which particularly high accuracy requirements are required for the setting of the crossing ratios to be maintained due to the rapidly growing coil diameter, are wound in a wild winding and that a step-precision winding is only produced in the remaining areas.
  • This method takes into account the fact that the necessary changes in the traversing speed must be made so quickly, especially at the beginning of the winding travel, that the exact and abrupt setting of a changed crossing ratio by changing the traversing speed is possible only with disproportionately great effort, in particular because of inertia and vibration behavior is.
  • Japanese patent specification 47-49780 discloses a method in which a wild winding and then a precision winding are used at the start of the winding cycle. This is done in order to be able to lower the traversing speed at the beginning of the winding travel.
  • the traversing speed is reduced by Use of the step precision winding, while the use of the wild winding has the purpose of avoiding the switching of the traversing speed, which is necessary for a step precision winding, in the areas of the winding travel in which very frequent switchovers with high accuracy are required.
  • a wild winding is thus used at the beginning of the winding cycle, while a step-precision winding takes place in the rest of the winding cycle. This is particularly advantageous if the traversing speed is also to be increased at the start of the winding cycle.
  • the invention is based on the knowledge that the mirror problems that arise when winding a thread on spools with a relatively small diameter or with changing Chaniger speed can also be solved in a satisfactory manner with relatively little effort even in the method of wild winding . It is possible to keep the traversing speed constant at all during the region of the winding travel in which winding is carried out in the wild. This is always possible if the resulting mirrors are run through very quickly with a rapidly growing bobbin diameter (e.g. with thick thread titers and high thread speeds).
  • the thread is laid in a so-called stepped precision winding.
  • An upper limit of the traversing speed and a lower limit of the traversing speed are set. The difference between the two is about 4% of the upper limit.
  • the traversing speed is then first reduced proportionally with the spindle speed in such a way that a certain pre-calculated crossing ratio (winding ratio) is maintained.
  • the traversing speed is suddenly increased to a value which is close to or on the upper limit and which in turn results in a lower, predicted crossing ratio.
  • the step precision winding method is followed both in the areas with constant average traversing speed and in areas with decreasing, medium traversing speed.
  • the traversing speed can also be overlaid with a mirror disturbance caused by wobbling.
  • the traversing speed fluctuates around the mean value with an amplitude of approx. 2%.
  • Such mirror interference methods are e.g. described in DE-OS 28 55 616.
  • a method for avoiding mirrors can also be used, in which the traversing speed temporarily increases suddenly from its base value to a value up to 4% higher than the mirror when it approaches a mirror, and then suddenly drops back to its base value becomes.
  • Such a method is described in EP-OS 83102811.
  • the method according to the invention has the advantage that it allows the production of a step precision winding even if the average value of the traversing speed is to be increased very greatly over distances of the winding travel.
  • Striker pieces of thread that emerge from the front edge of the bobbin and span inner layers secantially
  • Fig. 1 shows the cross section
  • Fig. 2 shows the view of a winding machine (partially schematic) on which the invention can be carried out.
  • FIGS. 1 and 2 The thread 3 running continuously in direction 2 is guided over the godets 28 and 30, which are driven by the motors 29 and 31 at different speeds.
  • the energy determining the speed of the godets 28 and 30 is supplied by the frequency converters 32 and 33.
  • the thread is stretched between them and then first passed at a constant speed through the stationary thread guide 1 and then through the traversing device 4.
  • the winding spindle 5 is freely rotatable.
  • An empty tube 10 is slipped onto the winding spindle 5.
  • the thread 3, which runs at a constant speed, for example freshly spun and / or drawn man-made fibers, is wound on the empty tube 10 to form a cheese 6.
  • the empty tube 10 and then the coil 6 that is formed are driven at their circumference by a drive roller 21 (not visible in FIG. 2) at a constant circumferential speed.
  • the thread 3 becomes longitudinal due to the traversing 4, which is described further below each cheese spool moved back and forth.
  • the traversing mechanism 4 and the drive roller 21 are mounted together on a carriage 22 which can be moved up and down (arrow), so that the drive roller 21 can avoid the growing coil diameter of the coil 6.
  • the thread 3 runs from the traverse 4 with a drag length L1 onto the roller 11, loops around it and runs tangentially onto the spool with a drag length L2.
  • the drag lengths L1 and L2 have the effect that the depositing length H of the thread on the bobbin or sleeve (see FIG. 8) is shortened by increasing the traversing speed and, according to this invention, when the base layer is wound from HB to H (FIG. 8).
  • the traversing 4 consists of a wing traversing and a roller 11 arranged downstream of it in the thread run.
  • the traversing has its own drive, described later.
  • Wing traversing and roller 11 are connected by gears (not shown).
  • the roller can be connected to the drive roller 21 in a geared manner.
  • the particular advantage of the traversing shown is that the deposit angle of the thread on the spool can be changed - within limits - since the traversing speed can be set independently of the winding speed.
  • the wing traversing has the rotor 12 and the rotor 13. Both rotors can be mounted concentrically or eccentrically to one another. Both rotors are driven in opposite directions by a drive and transmission described later in the transmission housing 20.
  • the rotor 12 carries two or three or four driver arms 8, which rotate in the plane of rotation I (arrow 18).
  • the rotor 13 carries the same number of driver arms 7 which rotate in the closely adjacent plane of rotation II (arrow 17).
  • the driver arms guide the thread along the guide ruler 9. Each driver arm 8 transports the thread - in FIG. 2 - to the right and transfers it there at the guide end to a driver arm 7, which transports the thread in the opposite direction to the other guide end, where in turn one of the driver arms 8 takes over the return.
  • the traversing device 4 is driven by an asynchronous motor 14.
  • the drive roller 21 is driven by the synchronous motor 20 at a substantially constant peripheral speed. This will be discussed later.
  • the three-phase motors 14 and 20 receive their energy from frequency converters 15 and 16.
  • the synchronous motor 20, which serves as a coil drive, is connected to the frequency converter 16, which supplies the adjustable frequency f2.
  • the asynchronous motor 14 is operated by frequency converter 15, which is connected to a computer 23.
  • the output signal 24 of the computer 23 depends on the input.
  • the input is made by the program unit 19, in which the following can be programmed: On the one hand, the course of the traversing speed, ie the control frequency f3, is entered via the winding cycle.
  • the mean value of the traversing speed and additionally the frequency as well as the amplitude and shape of the periodic deviation from the predetermined mean value are entered.
  • winding conditions can also be entered in which mirrors are to be expected. Above all, it is about the so-called integer winding ratios (spindle speed / traversing frequency) or winding ratios with a small denominator (1/2, 1/3, 1/4 ). These critical winding ratios are then avoided in that the traversing speed is increased suddenly from its base value shortly before the critical winding ratios are reached, so that the critical winding ratio is jumped through.
  • the course of the peripheral speed of the coil or - as shown here - the speed of the godets 28 and 30 can be programmed. This is based on the fact that with increasing traversing speed an increase in the thread tension with which the thread is wound on the bobbin occurs. It can now happen that this thread tension affects the thread quality and / or the quality of the package.
  • the invention provides that the speed of at least the godet 30 is adapted to the change in the traversing speed.
  • the speed of the godet 28 can also be increased accordingly, so that the speed ratio between godets 30 and 28 remains constant, and thus the stretching of the thread that takes place between godets 30 and 28 remains unchanged.
  • the course of the speed of the godet 30 and possibly also the godet 28 can additionally be entered into the program unit 19 and used via the output signal 25 of the computer to control the frequency converter 33 and possibly also the frequency converter 32 such that the speed of the godet 30 or the godets 30 and 28 is raised to avoid increased thread tension.
  • the main task of the computer 23 is to carry out the target value determination of the traversing speed. Details are described in European patent application 86103045.
  • the computer first receives through the program memory or program generator 19 the predefined course of the traversing speed, the predefined course of the upper limit and the lower limit of the traversing speed as well as the predicted ideal winding conditions.
  • the computer calculates "ideal" spindle speeds from these ideal winding ratios and the initial value of the traversing speed. The values of the "ideal" spindle speeds are compared with the current spindle speeds determined by the sensor 38.
  • the process begins Step precision winding.
  • the computer specifies as output signal 24 the output value of the traversing speed, which is also predetermined by programmer 19, as the setpoint for frequency converter 13.
  • the computer reduces this setpoint proportionally to the constantly measured spindle speed, which decreases hyperbolically with increasing bobbin diameter at constant bobbin peripheral speed.
  • the predetermined "ideal" winding ratio thus remains constant during this stage of the precision winding.
  • Output signal 20 specifies the output value of the traversing speed as the setpoint.
  • the upper value of the traversing speed is a fixed variable in the course of the winding cycle. It is always set when this variable results in a pre-calculated, ideal winding ratio in relation to the current spindle speed.
  • the lower limit value of the traversing speed is only a mathematical quantity that indicates the largest permissible drop in the traversing speed, which, however, is rarely or never achieved in reality and only plays a role in the calculation of the upper limit value. It should be noted that the process can also be controlled in reverse.
  • the lower limit value of the traversing speed can be specified as a real limit value that is repeatedly approached.
  • the upper limit indicates the largest permissible jump in the traversing speed upwards. However, in reality it is only approached in exceptional situations if this upper limit value happens to have an ideally calculated value in relation to the current spindle speed.
  • this rewinder e.g. programmed the traversing law according to the diagram according to FIG. 3 or FIG. 4 or FIG. 5.
  • the coil layer thickness S is plotted on the abscissa - starting from the sleeve diameter of 100 mm.
  • the ratio of the traversing speed to the peripheral speed of the coil is plotted on the ordinate, it being assumed that the peripheral speed of the coil is essentially constant.
  • the ordinate shows the tangent of the storage angle, which also results from the above-mentioned DIN regulation.
  • the diagram according to FIG. 3 shows that at the start of the winding cycle, i.e. with a tube diameter of 100 mm, a certain constant traversing speed is first specified, the average crossing angle of which, e.g. is equal to 5 °.
  • a mirror disturbance can be superimposed on this traversing speed by known methods, so that only the mean value of the traversing speed is constant.
  • This constant traversing speed is maintained until a predetermined, first ideal winding ratio is reached.
  • the coil has reached a thickness at which the diameter no longer changes as much over time.
  • the traversing speed is reduced in proportion to the decreasing spindle speed until the traversing speed approximately reaches its lower limit value UGC.
  • the traversing speed is suddenly increased again to approximately its upper limit value OGC, so that the next programmed ideal winding ratio is now set. This next winding ratio is maintained because the traversing speed is now reduced proportionally to the spindle speed until it reaches the lower limit value UGC.
  • step precision winding is only started when the spindle speed only slowly decreases.
  • the traversing speed in the individual stages of the stage precision winding only decreases slowly, so that in each stage, ie between the upper limit value OGC and the lower limit value UGC, the traversing speed is available for a sufficiently long time for the winding machine and the electronic control can come into stable operation.
  • the traversing speed or the quotient plotted on the ordinate is set relatively low at the start of the winding cycle, that is to say with the tube diameter 100, so that an average crossing angle of approx. 5 ° results.
  • the traversing speed is then steadily increased within the relatively small base layer with the layer thickness SB until an at least 3 ° larger, average depositing angle is reached.
  • the traversing speed has reached the range between the upper limit OGC and the lower limit UGC of the traversing speed.
  • the switchover takes place when the computer determines that the increasing traversing speed during winding of the base layer has reached a winding ratio which represents the first programmed, ideal winding ratio of the step-precision winding.
  • the switchover to step precision winding takes place when the increasing traversing speed has reached the lower limit of the traversing speed UGC.
  • the traversing speed jumps to Range of the upper limit of the traversing speed increases as soon as the upper limit in relation to the spindle speed results in the first ideal winding ratio of the step precision winding.
  • the traversing speed is then reduced in proportion to the spindle speed, so that this first programmed winding ratio of the step-precision winding is driven.
  • FIG. 8 shows that when the base layer SB is wound, a mirror disturbance can also occur due to periodic (or also aperiodic) changes in the traversing speed.
  • the mean value MWC of the traversing speed increases steadily, as was previously described for the traversing speed when winding the base layer.
  • the actual value of the traversing speed fluctuates with an amplitude of ⁇ 1% around the mean value MWC. It is from the St.d.T. known that the symptoms of mirror formation can be avoided.
  • FIG. 9 shows another method for avoiding mirrors when winding the base layer SB.
  • the mirror values 12 and 11 are shown in the diagram according to FIG. 9.
  • the winding ratio of spindle speed to traversing frequency is an integer equal to 12 or 11, respectively.
  • the basic value of the traversing speed increases, as was described above for the traversing speed.
  • the traversing speed is increased suddenly.
  • the increased value is then maintained until a downshift is possible without the risk of mirror formation.
  • 9 shows the basic value of the traversing speed as a rising straight line over the winding layer SB of the basic winding with BC.
  • the area of the mirror 12 and 11 there is a temporary increase in the traversing speed and then a switch back to the meanwhile increased value of the basic traversing speed BC.
  • FIGS. 6 to 9 it should be mentioned that these figures also use the abscissa and ordinate of FIG. 4 on an enlarged scale.
  • the method corresponds to that according to FIG. 4.
  • the layer thickness SB is reached, the traversing speed is not increased any further. Rather, it remains constant until a total layer thickness of 50 mm is wound.
  • the wild winding comprises two phases, namely a phase in which the traversing speed is increased and a further phase in which the traversing speed remains constant. During the two phases, conventional mirror disturbance methods can be applied and superimposed. After reaching the total layer thickness of 50 mm, i.e.
  • the distance between the upper limit and the lower limit of the traversing speed is constant in the step precision winding.
  • An increased jump height has the advantage that the time interval between the switchovers increases. Therefore, an increased jump height, especially at the beginning of the winding trip, i.e. applied at the beginning of the stage precision winding phase. The jump height can then be reduced continuously or continuously, since the switching frequency also decreases. This will be explained with reference to FIG. 5.
  • the jump height decreases at the beginning of the precision winding, in that the upper limit value of the traversing speed is first set high and then reduced to a constant value.
  • the godet speed vG also contain a diagram of the godet speed vG, the godet speed being given as a percentage of the initial value. From the diagram it can be seen that the initial value of the peripheral speed is increased by approximately 1% in the course of the winding of the base layer, so that inadmissible changes in the thread tension are compensated for and, ideally, the winding speed remains constant.
  • the sleeve diameter is plotted on the ordinate
  • the base layer thickness SB is plotted on the abscissa. It follows that the base layer thickness is inversely proportional to the sleeve diameter. It was found that a good, stable and rack-free coil construction can be achieved.
  • the layer thickness SB of the base layer at which the maximum average value or the maximum limit values of the traversing speed should be reached, should be between 14 and 16 mm .
  • S A (100 -r) / 100, where r the sleeve radius, given in millimeters and A is a value between 24 and 34.
  • Factor A is the thread tension with which the thread is wound. Within this framework, A can be determined by experiment. The higher the winding tension, the lower the factor A.
  • the tipping tendency could be reduced in particular by choosing the mean values or limit values of the initial traversing speed to be very low in such a way that the deposit angle of the thread on the sleeve is not more than 5 °. On the other hand, the deposit angle at the highest traversing speed is no more than 10 °.
  • the difference between the maximum traversing speed and the minimum traversing speed or between the largest and the smallest placement angle is used to control the slope angle.
  • This invention provides that in order to achieve straight end edges, the difference between the largest and the smallest placement angle should be at least 3 °.
  • Fig. 12 shows the theoretical view of a cheese 6 according to this invention, which is formed on the sleeve 10 with the radius r and the diameter d and has the total layer thickness S.
  • the cheese is cylindrical and has practically essentially straight end edges which lie in a normal plane.
  • the coil theoretically has oblique front edges with a theoretical angle of repose alpha.
  • the intersecting thread turns on the outermost layers of the bobbin are indicated with the deposit angle that each piece of thread has relative to the tangent to the bobbin lying in a normal plane to the bobbin.
  • the base layer serves as a side support for the coil. This support prevents the end edges of the spool from bulging out laterally and causing strikers.
  • the theoretical cone angle alpha of the base layer is between 65 and 80 °. This is mainly achieved by gradually increasing the traversing speed - starting from the smallest deposit angle - during the winding of the base layer until the largest deposit angle is reached, the difference between the smallest deposit angle and the largest deposit angle - as mentioned - at least 3 ° is.
