Definitions

  • the invention relates to a method for rewinding yarns with a rewinding speed, comprising the steps of unwinding a yarn from a supply spool, and winding the yarn on a yarn carrier rotating with a wind-up speed, the yarn being guided over the yarn feed from the supply spool to the yarn carrier, and a yarn feed Device for carrying out the method (rewinding device).
  • rewinding device for carrying out the method (rewinding device).
  • Such rewinding devices are used in particular for producing reels with yarn windings adapted to a subsequent process.
  • the rewinding should be carried out with the highest possible winding speed (rewinding speed).
  • rewinding speed the highest possible winding speed
  • yarn tension of the yarn to be rewound during the rewinding process and yarn tension variations are more pronounced.
  • the latter leads to a deterioration in the quality of the winding on the coil created, since thread tension fluctuations during winding lead to Garn Whyschwankungen of the windings.
  • the latter can in turn worsen the unwinding of these coils in subsequent processes.
  • the thread tension variations can easily lead to thread breaks during rewinding.
  • the latter occurs especially in areas of integer Windungsgue, ie the ratio of coil rotation to Doppelhubiere, so-called mirror zones, the supply coils heaped up. In these areas, the thread layers are close to each other without being fixed by crossing points, which can lead to entrainment of adjacent threads and thus thread tension peaks or thread breaks in the overhead deduction. These thread tension peaks severely limit the rewinding speed.
  • the yarn tension of a yarn is measured in the yarn path after a conditioning shortly before its winding. It is attempted to keep the yarn tension in a predetermined yarn tension range constant by means of a yarn tension control module according to a control variable derived from the measured yarn tension.
  • the yarn tension control module in this case comprises a yarn brake and / or a controllable delivery mechanism, by means of which the yarn tension is regulated by braking and / or accelerating the yarn speed of the yarn.
  • the yarn is withdrawn from the supply spool by the rotating movement of a take-off roll (deduction feed).
  • the take-off roll typically includes a main engine-driven roller and a passive separation roller that determines the geometry of wraps of the yarn about the main roller.
  • a passive separation roller that determines the geometry of wraps of the yarn about the main roller.
  • the invention has for its object to provide a method and an apparatus for rewinding of yarns, which avoid the disadvantages of the prior art and in particular at a high rewinding speed enable the production of coils with windings high quality.
  • a rewinding speed control amount of the yarn from the supply reel preferably in the yarn course before a take-off supply setting a take-off speed, is determined or the rewinding speed control amount of the yarn becomes initial the yarn course is determined before a deduction delivery and / or a brake and / or a lubrication and the rewinding speed is controlled by a control module in response to the Umspul Oberskontrolliere.
  • the inventive method is based on the finding that the causes of most thread tension fluctuations of parameters of the supply spool, or parameters with which the yarn is unwound from the supply spool depend.
  • the rewinding speed control quantity is thus determined by the feed reel during the reeling operation in a case of several possibilities. If an increase in the thread tension of the yarn is detected or expected via the rewinding speed control variable, then the rewinding speed is temporarily lowered, for example by controlling the takeup speed. Alternatively, for example, the rewinding speed can also be regulated by controlling the take-off speed.
  • the thread tension in the Abspulregion is stabilized, so that a regular profile of the thread tension over time, regardless of, for example, the diameter of the supply spool is maintained. This ensures a consistent quality of the produced windings on the yarn carrier. Furthermore, it is possible to increase the production speed of the production process while maintaining quality, since thread tension peaks are avoided.
  • the stabilization of the withdrawal thread tension is dependent on the rewinding speed.
  • the rewinding speed is the manipulated variable for the take-off thread tension. The objective here is to maximize the rewinding speed based on the pull-off voltage as a controlled variable. Increasing production speed is the primary goal here. An equalization of the winding tension is a positive side effect.
  • the thread tension can be independent of the quality of the yarn, the diameter of the feed bobbin and the selected unwinding speed kept constant. In addition to being able to increase or decrease the thread tension during unwinding, if necessary, the thread tension can be permanently reduced, thereby enabling higher production speed and efficiency.
  • a withdrawal thread tension preferably by measurement by a thread tension sensor, is preferably determined as the rewinding speed control variable. This provides a simple and inexpensive way to determine the Umspul yorkskontrolle size.
  • the determination of the rewinding speed control variable can advantageously be carried out via desired rewinding speed values as a function of a current diameter of the supply reel and / or the current weight of the supply reel and / or the length of the yarn still remaining on the supply reel and / or optical monitoring data of a rewinding bobbin of the supply reel and / or optical monitoring data of mirror zones on the supply spool done.
  • the remaining length of the yarn still present on the supply bobbin can be determined from the already rewound length (running length) of the yarn with known total length. As a result, a thread tension fluctuation can be counteracted even before it occurs by reducing the take-up speed.
  • a threadline tension preferably a take-up thread tension
  • the take-off speed of the take-off feed mechanism is regulated as a function of the threadline tension and / or a yarn speed in the thread run is regulated as a function of the threadline tension by means of a thread brake module arranged in the thread run.
  • the winding tension is thereby separated from the take-off speed, which is advantageous in particular during rewinding processes with interposed yarn processing.
  • the rewinding device according to the invention is set up to carry out the method according to the invention and thus provides the advantages of the method according to the invention.
  • a take-off delivery unit is provided in the yarn path, set up to set a withdrawal speed of the yarn, wherein the control-size receiving means are adapted to determine the Umspul einskontrolle size in the yarn path before the deduction delivery.
  • This embodiment is particularly suitable for overhead removal of the supply spool.
  • the rewinding unit can be set up to drive the deduction delivery unit, wherein the control module is then set up to regulate the rewinding speed by controlling the withdrawal speed.
  • the rewinding device when the control size receiving means comprise a thread tension sensor, set up to determine a take-off thread tension by means of measurement as the rewinding speed control variable.
  • the rewinding device may comprise a threadline tension control module adapted to measure a threadline tension, preferably a take-up thread tension, by means of a thread tension sensor and to control the take-off speed of a take-off feed as a function of the threadline tension and / or a yarn speed in the threadline as a function of the threadline tension by means of a threadline disposed To control thread brake module.
  • a threadline tension control module adapted to measure a threadline tension, preferably a take-up thread tension, by means of a thread tension sensor and to control the take-off speed of a take-off feed as a function of the threadline tension and / or a yarn speed in the threadline as a function of the threadline tension by means of a threadline disposed To control thread brake module.
  • a yarn processing machine has at least one rewinding device according to the invention.
  • FIG. 1 shows a rewinding device according to the invention.
  • FIG. 2 shows the thread tension as a function of the spool travel in front of the take-off delivery unit of a rewinding device according to the prior art.
  • FIG. 1 shows a rewinding device 1 according to the invention for rewinding yarns.
  • the yarn is unwound from a supply spool 3, which is arranged in a feed bobbin receptacle 4 for overhead removal.
  • a yarn carrier 7, on which the yarn is wound, is arranged in a yarn carrier receptacle 8.
  • a not shown Umspulaggregat that is designed as a winding unit for driving the Garnchtfact 8, drives the Garnchtfact 8 such that it rotates at a take-up speed.
  • the rewinding unit is an electric motor which engages the yarn in such a way that it can at least influence the rewinding speed.
  • the Yarn is guided while wrapping in a yarn path 10 of the supply spool 3 to the yarn carrier 7.
  • the yarn path 10 forms a discharge balloon 11.
  • a thread guide not shown, which allows an orderly yarn winding on the yarn carrier 7, the yarn path 10 is widened funnel-shaped in front of the yarn carrier 7.
  • a thread tension sensor 15 in the yarn path 10 is provided as a control size receiving means in front of a take-off feed unit 17 which determines the take-off speed of the yarn by its rotational speed.
  • the yarn tension sensor 15 measures withdrawal tension values of the yarn take-up yarn tension from the supply bobbin 3 in the yarn path 10 before the take-off supply unit 17 continuously.
  • the rewinding device 1 further comprises a threadline tension control module 20.
  • This yarn thread tension control module 20 is set up to measure a yarn thread tension in the yarn path 10 shortly before the yarn carrier 7, that is to say a take-up yarn tension, by means of a further yarn tension sensor 22.
  • the take-off speed of the take-off delivery mechanism 17 is regulated by the thread-yarn tension control module 20 as a function of the threadline tension.
  • the yarn speed in the yarn path 10 can be regulated as a function of the yarn thread tension by means of a yarn braking module 25 arranged in the yarn path 10.
  • FIG. 2 shows the thread tension S in centinewtons [cN] as a function of the spool travel t in front of the take-off delivery unit of a rewinding device according to the prior art.
  • Under coil travel t is the time course of the entire Abspulvonreaes understood.
  • the thread tension S increases with increasing unwinding of the supply spool, with their fluctuations increasing sharply.
  • the increase in the yarn tension S has its main cause in the decreasing supply spool radius, which leads to higher speeds of the yarn at the same take-off speed.
  • the transition between different mirror zones of the supply bobbin results in a strong short-term increase in thread tension (thread tension peaks 33).
  • the method according to the invention makes it possible to avoid, as far as possible, thread tension fluctuations in particular also in mirror zones during the entire reel travel t.
