Abstract

The yarn (F) is drawn off a supply (2) by a yarn feed system (5) and delivered to a winding advance system (11) in a textile machine, wherein a controlled variable for the feed speed of the yarn (F) is obtained. The disturbances causing the fluctuations in the yarn tension are distinguished according to periodic and stochastic disturbances. The periodic disturbances are calculated and taken into account for the said controlled variable. The calculated periodic disturbances are taken as a basis for adapting the feed speed, which is increased or decreased in accordance with the respective position of the yarn guide (12) of the winding advance system (11). The yarn tension is measured by a sensor (6) arranged between the feed mechanism (3) and the winding advance system (11), and the stochastic disturbances which are measured in this respect are also taken into account for the said controlled variable.

Field of the Invention This invention relates to a method for adjusting the tension of a yarn in a textile machine, wherein the yarn is supplied by a yarn feeding system. Dragged and transported to a winding propulsion system, where it can be used for yarn feed speeds - controlled by several techniques in various processes such as the textile industry, such as winding processes, in order to make the process under discussion One of the prerequisites for the optimum and uniform quality of the manufactured product is a fixed yarn tension. However, the yarn tension will often vary greatly in the winding process depending on the quality of the supply bundle, such as the quality of the dyeing or the like, and the winding speed. It has been proposed that a fixed yarn tension may be obtained. The scheme of the various devices, m P = l is described in the patents DE-(38 24 034, >> EP-A-0 950 742, in the patent DE-C-38 24 034 In the case of a yarn consuming machine comprising one of a plurality of yarn processing stations and in particular a circular knitting machine, a corresponding amount of feeding device for the silk material is provided. A yarn tensioning device that cooperates with a material and that includes a pick-up and a circuit for measuring the yarn is provided at each of the feed stations. The yarn is controlled as described in the patent application No. EP-A-0 950 742. Delivered to a needle Or a device for a textile machine such as a winder, comprising a sensor for measuring the tension of the yarn, a device for measuring the feed speed of the yarn, and for accurately setting the two-parameters - The controller of the yarn 1251576 V. Description of the invention (2: ) The feed rate is preferably adjusted based on the yarn tension. The patent case of charer Sc hwe iter Me tt 1 er AG: EP- No. 0-875 479 describes a similar device in which the winding machine will cause a slight increase or decrease in the yarn tension due to the problem of yarn shortening or elongation due to the linear movement of the winding propulsion unit. The tension variation will be corrected by the time delay caused by the inertia of the sensor and the controller. SUMMARY OF THE INVENTION The present invention is improved for adjustment in a textile machine. The conventional method and apparatus for the tension of the thread makes it possible to significantly improve the winding process in the direction of quality and/or efficiency. The invention can be achieved according to the invention of the method mentioned at the beginning. The disturbance causing the variation of the yarn tension is based on the periodic and random disturbances Is calculated and the periodic disturbance is calculated and used to consider the controlled variable, based on the achievement of the invention, based on the knowledge The change in the thread tension does not only have a single cause, but is based on both the main cause of the disturbance caused by the pulling of the yarn out of the supply bundle and the disturbance caused by the winding propulsion system and which are caused by the dragging process. The disturbance system is random and the origin of the winding propulsion system can be determined by geometry and can be calculated 〇 and 5 It has been shown in the study that the periodic perturbation is substantially larger than the randomness, so that the periodic perturbation alone can be calculated in a computational manner to achieve a yarn tension of substantially the same amount of -4, and can be further 1251576. DESCRIPTION OF THE INVENTION (3) It is possible to obtain the yarn tension of substantially the same amount without providing a yarn tension sensor, which can greatly reduce the cost. A first preferred embodiment of the method according to the invention is characterized in that the yarn tension is measurable and the controlled variable is also taken into account in the random disturbance thus measured. This also corrects the random disturbance so that a substantially constant yarn tension 値 is obtained. A second preferred embodiment of the method according to the invention is characterized in that the calculated periodic disturbance system serves as a basis for adapting the feed rate and the feed speed is based on each of the yarn guides Increase or decrease by location. According to a third preferred embodiment, the adjustment adjustment causes the yarn tension to reach the same number at both the reversal point and the center of the yarn guide movement path. The invention also relates to a device for adjusting the tension of a yarn in a textile machine, comprising a motor-driven feed mechanism for the yarn, and a winding propulsion system provided with a yarn guide. And the winding propulsion system is used to wind the yarn onto a yarn carrier. Apparatus according to the present invention, characterized in that the drive means of the feed mechanism is adjusted to compensate for the periodic disturbance of the yarn tension caused by the winding propulsion system. According to a first preferred embodiment of the apparatus of the present invention, The sensor is characterized in that: a sensor for measuring the tension of the yarn is disposed between the feeding mechanism and the winding propulsion system, and the driving device of the feeding mechanism is adjusted to supplement 1251576. 5. Description of the invention (4) In addition to the periodic disturbance, the yarn tension random disturbance measured by the sensor is compensated. A second preferred embodiment of the apparatus according to the present invention is characterized in that, based on a calculation of the yarn tension for each position of the yarn guiding member, the driving device for adjusting the feeding mechanism is adapted to Compensates for periodic disturbances in yarn tension. This calculation is preferably related to the instantaneous yarn speed. The position of the yarn guide is determined by a sensor or predetermined by a control stage. A further preferred embodiment of the apparatus according to the invention is characterized in that a first control stage is provided for the yarn carrier and the drive of the winding propulsion system, and a second control stage is connected to The first one is used for the drive of the feed mechanism, and information about the instantaneous position of the yarn guide and the instantaneous yarn tension is transmitted to the second control stage. The invention also relates to an application of the method to a winder. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail based on a specific embodiment and a single drawing, which is a schematic diagram of a winding station of a winder. As shown in the figure, the winding station includes a bobbin 1 for holding a supply bundle 2 of a yarn F, a yarn inspection mechanism 3, a feeding mechanism 5 driven by a motor 4, A sensor 6 for measuring the tension of the yarn F, and a winding unit 7. The winding unit includes a mandrel 8 driven by a motor (not shown) for holding and mounting a bundle of tubes 9, and a winding propulsion system 1 1 in which a bundle of packages 1 is wound around the bundle On the tube. Another 1251576 V. INSTRUCTIONS (5) One option is to drive the bundled package 10 by a motor-driven friction roller on which the bundle 1 is placed (see, for example, the patent case) EP-A-1 1 25 878). The winding advancement system 1 1 includes a yarn guide member 1 2 as the most important member, and the yarn guide member performs a oscillating lateral movement along the axis of the bundle package 1 . A type of winding and propulsion system of this type is disclosed in, for example, Patent No. EP A- 0 829 444 (= US-A- 5 9 18 829), EP-A-1 1 25 878, EP -A- 1 209 1 1 4 and EP-A-1 219 559, and the entire disclosure of which is hereby incorporated by reference. The yarn guide 12 is fastened to a sliding member 13 which is movable back and forth in a track or grooved guide and a transverse member 14 is actuatable on the sliding member. The transverse element is composed of a flexible member that is rigid in the lateral direction and transmits tensile force, and is composed of, for example, a string, a metal wire, a metal rope, a flat, toothed or V-belt, a metal belt. , a chain or similar form. The transverse element 14 is operated on two rollers 15 and 16, and, for example, one of the rollers of the roller 16 in the drawings acts as a drive wheel for driving the transverse element 14. The drive wheel 16 is driven by a servo motor (not shown), and preferably a stepper motor. Drive wheel 16 is preferably fastened directly to the motor shaft. A sensor (not shown) is coupled to the motor to detect the rotational position of the drive wheel 16 and thus the lateral position of the yarn guide 12. Reference is made to the patent of the sensor No. ΕΡ-Α- 0 829 444 and the corresponding patent No. US-A-5 9 1 8 829. The sensor is a photo-electrical sensor comprising a transmitting and receiving diode and sensing the driving wheel 1251576. 5. The invention (6) 16 or the movement of one of the driving wheels is firmly connected. . For this drive wheel 16 or the belt wheel is provided with an optically sensed field mark, such as a hole or slot along a circle. The drive shaft of the mandrel 8 and the drive wheel 16 , the sensor for the yarn guide: 12 transverse position and any further sensors for bucking the rotational speed of 10 , are connected to a mandrel Controller 1 7 and the controller controls the motors based on stylized winding parameters and winding rules, as well as information provided by the sensors. The spindle controller 17 is additionally connected to the -* feed controller 1 8, which in turn is connected to the yarn tension sensor 6 and the drive motor 4 of the feed mechanism 5. The yarn tension sensor 6 measures the so-called random variation of the yarn tension and transmits the deviation signal to the feed controller 1 8, wherein the random variation is caused by pulling the yarn out of the supply bundle 2, and Disturbance caused by feed system 5. The feed controller 18 calculates the controlled variables necessary to correct the deviation, and transmits a corresponding control signal to the motor 4°. In addition to the random variation in the yarn tension, the winding propulsion system 11 also occurs. The cyclical changes caused. A general observation of the geometry of the winding propulsion system can be found - due to the linear movement of the yarn guide 12 - the transverse movement of the yarn F between the yarn guide and the yarn tension sensor 6 The point to the point is longer than the center. This case is indicated by the dashed arc B, and the difference in length between the two limits is indicated by the reference symbol i, which corresponds to the difference in yarn tension and the yarn at the reversal point. The thread tension is greater than the center. The yarn tension will therefore reach its 1251576 at a commutation -8-point, the invention (7) maximum enthalpy, and gradually decrease toward the center, at which the minimum enthalpy is reached, and then increases again until Until the reversal point. Since the geometry of the winding propulsion system 1 is known, the difference in yarn tension relative to a reference enthalpy can be calculated for each point of lateral motion, which will be implemented in the feed controller 18 and The feed controller 18 receives the detailed position of the yarn guide 12 from the spindle controller 17 for this purpose. The feed controller 18 calculates a controlled variable required to correct the periodic tension change and performs an adaptive adjustment to the yarn feed system based on the two controlled variables to compensate for the tension variation. For example, if the adjustment adjustment is implemented such that the yarn tension at the point of reversal is the same as the yarn tension at the center of the bale, the periodic disturbance will be substantially completely compensated by the winding propulsion system 11. Since the maximum amplitude of the periodic tension variation is a multiple of about three to five times the maximum amplitude of the random tension variation, the adaptive adjustment of the yarn feed system will compensate for most of the disturbances. Since the major part of these tension variations is periodic, it is also possible to dispense with the sensor 6 in certain applications, such as inexpensive structures, and to compensate for the tension disturbance only by the periodicizer.
