A pulling process takes place in an area which is through a pair of feed rollers and a pull roller is limited. The ratio of the peripheral speeds of the feed rolls to that of the pulling roller is referred to as the pulling ratio. In the known device, a twist is used carried out according to the ring twisting process, in which the Yarn over an upper öae and one guided by means of a ring Runner is wound onto a thread core for the purpose of forming a thread package. Between the upper eyelet and the In the runner, the yarn forms a "balloon". That completely up The method carried out on the draw-twisting machine to produce a yarn lap is hereinafter referred to as change. The further development of Zugzwirnnjaechinen is special :! aimed at increasing the drawing speed without deteriorating the quality of the yarn to be processed. If an increase in the train speed not only leads to the desired increase in production but also to a Would lead to deterioration in the quality of the yarn obtained, there would therefore be difficulties with a further one Processing of the product and / or a higher percentage of inferior quality material. According to the known Method is the speed of the winding spindle programmed, also at a relatively high train speed the balloon tension is kept on the permanently permissible word during the change and at the end of the week the LUufergeachwindigkelt still a permissible value having;. The word range of the spindle speed is indicated by o a Programiorunzaeinheit controlled, in which a

Programo carrier in the form of a program memory card is provided. The program carrier is deflected at a constant speed by a drive element and supplies the reference variable for an automatic control circuit in which the drive mechanism for the winding spindle is included as a component. In this control loop, the actual value speed of the winding spindle is compared with the guide variable, which represents the setpoint spindle speed. When a difference zwiechen the two speeds is present, a correction is obtained which .these differ- ence ™ reduced .. M

The known method has the advantage that it can only be used in an advantageous manner for a particular value of the train speed, which is expediently referred to below as the program train speed. When the train speed is different from that Programmzuggeschwindigkeit, it would dig primarily notwen _T to perform under the assumption of equality of other conditions, the g program in accordance with sooner or later, depending on whether the train speed higher odar lower than the Programmzuggeschwindigkeit is. It is true DNSS this problem by deflecting the Programarträgors old correspondingly higher or lower Geechwinäigkei · ^5; would be solvable, but this results in a second and even stronger negative part. If a different 'value is used for the train speed and the duration of the

BATH ORIGINAL 209808/0458

Program are simply lengthened or shortened accordingly, the range of values for the balloon tension is different from that of the Program train speed occurring value ranges. For example, if the balloon tension during the change if the program train speed is constant, this no longer applies to the changed train speed. this implies that if the pulling speed V is to be changed, the range of values of the balloon tension remains unchanged is held, a different program er-φ is required. This program must therefore pay particular attention to the φ setpoint pulling speed and the setpoint range of the balloon tension be adjusted.

The draw-twisting process is influenced not only by the drawing speed but also by other parameters, for example the twist, the linear density of the yarn, the length of the yarn to be taken up in the package, the shape of the yarn package and the type of yarn to be processed. Each of the quantitative parameters in this series must be able to take on a sufficient number of values, and it must also be possible to use a variety of winding formats and types of yarn. If the Zugzwirnvorrichtung such wide-span needs to meet these parameters with respect to a large number of Programniapeicherkarten should be at your disposal. It is assumed, for example, that in the known draw-twisting device one and the same type of yarn is to be processed in a yarn package and that for each of the parameters, namely the tensile speed

209808/0458

tenacity, twist, linear density and yarn length, it must be possible to select five different bu values. If it is further assumed that it must be possible to use these five parameters in any combination 2m, then the required number of program memory cards is 5 * * 625. If in the above example it is to be possible to make only a selection from five different train speeds , the required number of program memory cards increases from 5 * ¹² 5 to 5 * 625, as an increase of 500 program memory cards results. -

The disadvantage of a large number ron Prograiamspeicherkarten occurs not only when the balloon voltage to be obtained aufreoht during the change of a certain Werteberelch. This disadvantage also occurs in the following pail. If, in a draw-twisting device which works according to the bingewinder method, the rotor rings are arranged at an incline with respect to the winding spindles, the structure of the winding presents the same problem as in the case of winders Occurrence of mirror images in some yarn layers. Therefore, μ eusEtellch passed to the Hmupiquerbewegung the BlngeohienQ \ or Spindelbewegeretange a Unterquerhewegung on 'which dee from the inclined position the rotor ring arglbf.

If in a titanic moment during the change Let the number of layers attached to the yarn package per unit of time be an integral multiple of the Läufergeechwindigkelt at the specific moment, the yarn layers are on adjacent to the coil or at least very close together. In winding machines, this effect is the formation of a mirror pattern known. Since the speed of the main transverse movement is many times less than that of the sub-transverse movement, the main transverse movement has only a small influence on the mirror pattern formation. A mirror pattern will be also formed when the runner's speed is an integer Multiple of the number of yarn layers attached per unit of time 1st.

The formation of a mirror pattern can be prevented by suitable programming of the speed n_ of the winding spindle. For this purpose it is necessary that during the change the speed of the winding spindle runs through such a range of values that nowhere the quotient (n _g - n ^) / n ^ nor the reciprocal of this can be an integer.

When the above-mentioned known method is used for winding thread packages without a mirror pattern it is therefore necessary to use a different program card as soon as the train speed is changed, jDeispialswöise from one value V ^ to one value V ^. Thus, as a result of the Repentance of the Susg

There is also a possibility of mirror pattern formation in that all other combinations of the values n _{ß of} the yarn package diameter el. PUr a "certain value of η and two different values V _& and V ^ of the suction speed are the values of dL _f at which mirror pattern, If at the pulling speed V ^ the spindle speed n _Q as puncture of the winding diameter d runs through the same values as at the pulling speed V_, the possibility of the formation of mirror patterns is not completely eliminated Pail it is therefore not sufficient to just leave the train speed program on.

The purpose of the present invention is to modify the aforementioned known method in such a way that the required number of programs is reduced. This is achieved essentially by the fact that the program contains a quantity which runs as a puncture of the variable ν through a range of values, each of which is proportional to the speed η (v) of the winding spindle, which at ^ f is the corresponding value of the Variables and a particular feed speed V _Q öes to the winding device conveyed yarn is required that a size is formed which is proportional to the present feed speed V of the yarn, that the product V.η (v) / V _{Q is} formed and that of this product the value n (v) der

speed required at the feed rate V the Wloklungseplndel is derived.

The method according to the invention has the advantage that the speed at which the yarn is fed to the winding weighing device is no longer the program selection influenced. For example, this applies in the case of a A draw twisting device that, if the draw speed is changed, the programming unit does not have to be provided with a different program, as is the case according to the known procedure is required.

Any operation which leads to the product Vn _Q (v) / V _o can be used. _{The speed n Q} (v) can thus be included in the program, and the quotient V / V _Q can subsequently be generated, which is then tipped with the programmed n _Q (v) buI. Or the puncture η (ν) contained in the program can first be _{divided by V Q} and the resulting quotient multiplied by V.

The method according to the invention is preferably characterized in that the program contains a variable proportional to the quotient ⁿ ₀ (v) / V _Q if »·!;, Then a variable proportional to the applied feed rate V dee . the winding device conveyed yarn is formed, that the product Vn _o (v) / V _{o is} formed and that of this

The method according to the invention can be carried out in various ways. For example, the conveying speed of the yarn can be measured by guiding the yarn through a cord, a running wheel of low friction or the like by determining its angular speed. Purely sensitive yarns are, however, unfavorable when they come into contact with any element which induces continuous friction, and furthermore, a slack-free drive of the line impeller is unfavorable

Preferably let the device designed such that the Means comprise a pulse generator which emits a pulse, the frequency of which is proportional to the speed of travel of the yarn, and that a pulse divider is provided, which is fed to the coil, the frequency of the α the pulse emitted by the pulse generator is set under the control of the programming unit according to the program size "

With such a device, the influence of the yarn feed speed on the desired range of values the speed of the weighing spindle is eliminated from the programmability. The programming unit can be the Frequency of the pulse emitted by the pulse generator ™ Bring such a * value that the frequency represents the desired value-P in the range of the spindle speed at the set feedrate. If the 4-way drive of the winding spindle is controlled by the pulse, the speed can of the winding spindle can be set so that »the desired value range follows. The size proportional to the feed rate of the yarn is then determined by the Frequency of the Bilse is shown. The programmed size is in this case divided by the Beaiprok value of the

Frequency shown. The use of a pulse generator has the advantage that the relationship between the feed rate and the frequency can be brought relatively easily to the desired accuracy. For this purpose, it is sufficient to adapt the number of pulses emitted per unit length of the yarn that has passed to the desired accuracy. Also contributes to the accuracy that the relationship between the input variable se and the output of Pulegebers, in this Pall the relationship between the Vorechubgesehwindigkeit and pulse m frequency, independent of the influence of temperature "of aging and the like, what else could have a disruptive effect in the case of anal ogrogation .

The invention is explained in more detail with reference to the drawing which shows part of a device, is subjected to a yarn of a Zugbehanditrag at dor and following wound demand * Fora in a package.

Viokele wound up. The yarn is immediately twisted with the tension twisting machine. It is assumed in the following that the device shown in the drawing relates to a position of a tension twisting device, since the idea of ignition can be used as a special advantage for such a machine. Since you are familiar with the structure of a Zugwiromaschine ISt ₁ , the drawing shows only those components which have to be mentioned for an understanding of the invention.

According to the drawing, a pulling roller 1 forms part of a (not silted) pulling device. In the spindle motor 2 drives a (not inclined) tficklungsapinäel the Twisting device on. With the pulley 1 is a pulse generator 3 coupled, which emits a pulse whose frequency is proportional to the speed of the pulling roller. This pulse becomes white Pulse divider 4, 5 ugled, which one or more exit tapules for a certain number of at their entrance emit appearing impulses. The frequency of the rare the PulsteHer emitted pulse is therefore only a Part of the frequency emitted by the Pulegeberβ 3 Pulse. The frequency division of the pulley plates 4, 5 is adjustable. The pulse controller 4, the frequency division of which is adjustable by hand is, its pulse as a stepping motor 6 from, the shaft of which is coupled to a progression unit 7 is. The Prpgaalerungselnheit 7 represents the frequency division of the pulse divider 5 during a change so that the

209808 / 0A58 bad original

" ¹⁹ " 171006T

Frequency of the delivered pulse corresponding to a desired range of values is changed. In the pulse divider 5 the frequency of the pulse representing the yarn feed rate corresponds to one that is multiplied by a magnitude Value which corresponds to the reciprocal of the frequency division.

The programming unit 7 comprises a program carrier in the form of a program memory card, which is known per se and is provided with projections which interact with microswitches M. The program memory card is advanced step by step ^ by the stepping motor 6. When changing, the program memory card is deflected by a given number of steps. Since the setting of the pulse divider 4 is adjustable, the step frequency can be easily adapted to the intensity of the change at any time. If the yarn package is to have a weight G, the duration t results. the change from the equation t * 9000 G / VT ₁ where ν is the pulling speed and T is the linear density in denier. The pulse generator 3 takes into account the train speed V, so that when setting the pulse divider 4, the change in G / T is the only factor to be taken into account.

It follows from this that the duration of the change is not a fixed quantity but depends on the time required is to make the program memory card one complete ^ movement can perform. This time is determined by the frequency

209808/0468

of the pulse emitted by the pulse generator 3 is controlled. Before the change is finished, the pulling roller 1 must therefore have performed a fixed number of revolutions. For each change carried out using a specific program memory card, a:; r given pulling speed and a given setting of the pulse divider 4, the same length of yarn is wound into a roll. A display element in the form of a second pulse generator S is coupled to the spindle motor 2, which emits a pulse whose frequency is proportional to the speed of the spindle motor and thus the winding spindle. This pulse and the pulse emitted by the pulse divider 5 are fed to a comparison module which is part of an automatic controller 10. This comparison unit compares the frequency of the two pulses. A converter consisting of an actuator 38 and a correction element 39 is provided between the comparison unit and the spindle motor 2. If the comparison module detects a difference between the frequencies of the pulses on it, the module adjusts the speed of the spindle motor 2 via the converter 3% 39 in such a way and over a period of time that the two compared pulse frequencies become the same again. Accordingly follows ¹ during the change the speed of the Spindelmotor3 2 and thus of the winding spindle that of the unit through the programming "7 prescribed range of values.

The pulse emitted by the pulse divider 4 is not only sent to the stepping motor 6 but also to two pulse divider 11,

209808/0458

fed. The frequency division of these pulse dividers is also set by the programming unit 7. The pulses emitted by the pulse dividers 11, 12 are fed to stepping motors 13, H, which transmit a rotary movement to screw spindles 15 and 16, respectively. Sliders 17, 18 are provided on the screw spindles to which switches 19 and 20 are assigned. The positions of the sliders determine the lower and upper point of origin of the transverse movement carried out by the ring rail or the rod carrying the spindle during the formation of the roll. To DIE ™ sem end, a rod 21 is provided, which jump a pre% 22 carries the old co-operates the switches 19 »20th The rod 21 performs a movement which corresponds to the transverse movement. When the ring rail or the spindle support rod moves in the upward direction and the projection strikes against the actuator of the switch 19, the direction of the transverse movement is reversed. The next reversal of the transverse movement takes place when the projection 22 strikes against the actuating member of the switch 13. The top | and lower reversal points can provide independent adjustment of λ are "To this end, the two programs on Progrananierungeeinheit 7, according to which the frequency-dividing the pulse divider 11 is set 12th If the winding is to have a symmetrical design, it is sufficient to use a program for setting the pulley dividers 11, 12.

The range of values for the speed of the winding spindle can

209808/0458

be chosen according to different requirements. For example, the range of values can be selected so that During the change, the balloon tension or the rotor rotation is constant. The choice can also be made that during the change the balloon tension or a different size test innate. Values run through, for example 2U the purpose, which also influence the yarn properties.

In particular, a range of values for the Bellone tension can be selected such that differences in yarn contraction, which can occur after the unwinding of tensile twisted yarns, are counteracted. The range of values can also be selected in such a way that mirror patterns are prevented from occurring in the yarn package. Such mirrors Water can 1 »case of Sugswlrasaschlnen ml ^ t inclined runner rings forms ge, if the ratio of the difference between the Spindeldrehsahl and Ißuferdrensahl bu the rotor speed is quite" ahlig itself or when der'Reeiprokwert this Ver ~ hältnlsses ganseahllg let.

In the influx, the balloon tension is special Should have a range of values, the corresponding program can be planned in the following way. Yarn of the type and the The linear density to be used is applied to a thread tube of a given diameter of the desired twisting strength with a «thread wrap of the desired shape» and the desired Weight wound up. During the change, the speed of the winding spindle, at which the balloon tension is the has the desired value, a function of a variable,

209808/0458

for example the time, which represents the build-up of the lap, or it is preferably the diameter jl of the yarn lap used. Let the range of values obtained in this way for the spindle speed be represented as a function of the winding diameter d by n _Q (d). Further, if the train speed used is 7 _Q , then a factor proportional to the quotient n _o (d) /? _o programmed. This size as a function of the winding diameter (L runs through values, each of which corresponds to the quotient n _o (d) / V _o in Beeng to a particular m

Value for d corresponds to. For the winding byaeaser d, this is _ Large, for example, proportional to the quotient n _Q (a) / 7

It now follows that the frequency of the pulse emitted by the pulse divider 5 is proportional to Vn _o (d) / V _Q , where Y represents the draw ratio used. The winding spindle is then automatically driven by the spindle motor 2 at a speed which is a factor V / V _o greater than when the train speed used is Y _Q. In this way the balloon tension is made independent of the height i of the pulling speed. This is based on the fact that, in order to obtain a given range of values for the balloon tension during the change, irrespective of the speed V, only the relationship n ^ dVn ^ d ^) has to be taken into account, where n + (d) the speed of the rotor corresponding to the value d of the winding diameter and n ^ (d ^) represent the speed of the rotor at the beginning of the change at a value of the winding diameter of d ^.

209808/0 * 58

If, in the case of the proposed method, a change in the pulling speed V is a proportional change in the rotation ~ number of winding spindles results, the values are n ^ one subject to proportional change. The ratio n. (D) / n. (D ^) therefore remains unchanged. Although no change

in which the balloon tension is constant, results

a change in the magnitude of the balloon tension.

Thus, changing the pull rate during the change will only result in a change in the level of balloon tension. This change can, however, be compensated for by using a runner with a different weight.

Although the process according to the invention and the device are of particular importance for draw twisting machines an application is not limited to this. The invention can also be used for drill pull and pull twist methods, if the yarn, as in the above examples, is wound in a winding driven by a spindle. Under drive by a spindle is to be understood that the yarn package is driven through the winding spindle on which the package is attached, and not by a rotary member which is in contact with the circumferential surface of the roll. For example the speed of the winding spindle must be changed during the winding process in this way that the circumferential speed of the yarn package is equal to the pulling speed of the yarn. If a difference
