Definitions

  • the present invention relates to a method for rewinding a thread and a device for performing this method.
  • the thread When rewinding a thread, for example from a spinning cop to a winding spool, the thread is laid by a thread laying unit on the surface of the spool.
  • the winding spool is driven by a drive motor.
  • Production output can be increased by increasing the wind-up speed without increasing the number of thread breaks. However, if the winding speed exceeds a certain limit, the number of thread breaks increases and this results in the upper limit of the production output. The higher the winding speed, the greater the tension in the thread. This explains the increase in thread breaks as the wind speed increases.
  • the winding speed is kept constant, it can be observed that the thread tension at the start of the winding of a template is small. Then the thread tension increases Slowly towards and towards the end of the rewinding process it rises steeply.
  • the winding speed is reduced during the entire rewinding process in such a way that during the final phase of the rewinding process, which is significantly shorter than the previous period of rewinding, there are as few yarn breaks as possible.
  • the pulling speed of the thread from the template should be high. Because of the structure characteristics of spinning cops, the running speed of the thread at the beginning of the bobbin (full bobbin) and thus the thread tension cannot be chosen too high, since otherwise entire layers (loops) of thread will be pulled off.
  • the winding speed should be able to be changed while the thread is being pulled off a template or spinning cop, so that the thread tension during the entire rewinding process is as close as possible but below a limit above which thread breaks frequently occur.
  • influencing variables are, for example, the thread speed and the thread tension.
  • the size of the thread tension can be controlled depending on the wind-up time by means of a corresponding program, on the diameter of the wind-up spool, on the original unwinding time or on a combination of these sizes.
  • Thread tension meter which Thread tension continuously measures.
  • the speed of the drive motor is adjusted so that this control deviation is reduced.
  • an electronically operable thread brake device can be controlled with the aid of an electronic control so that the control deviation is reduced.
  • the control signal used for this purpose can also be compared with a predetermined target value. If there are any deviations between the current control signal and the target value, the speed of the drive motor is adjusted with the aid of the electronic control so that this control deviation is reduced.
  • this known method does not yet enable the currently required increase in production output when specifying partly unwound templates.
  • the object of the present invention is to propose measures which make it possible to increase the production output beyond the previously usual limit.
  • the device shown for rewinding a thread contains a first bobbin 1, which is also referred to here as a template or spinning cop and from which the thread 2 is withdrawn.
  • the thread 2 then passes to a second spool 3, which is also referred to here as a winding spool.
  • This thread laying unit 4 can contain, for example, a grooved drum or a thread guide.
  • the thread laying unit 4 has a grooved drum 14.
  • the winding spool 3 is connected to a drive motor 5.
  • the shaft of the winding spool 3 can be connected to the motor 5.
  • the winding spool 3 can, however, also be driven on its circumference via a drive roller 6 or the grooved drum 14.
  • the speed of the engine is regulated by a speed controller 7, which is connected to an electronic control unit 8.
  • This can contain a microprocessor, which can control the processes in this facility according to the program.
  • a thread tension meter 9 On the path through which the thread 2 passes between the spinning cop 1 and the thread laying unit 4, there is a thread tension meter 9 and an electrically actuable thread braking device 10.
  • the knife 9 supplies the control unit 8 with information about the tension in the wound thread 2 and the brake 10 can be activated by the control unit 8 if necessary.
  • a thread length sensor 11 is provided for the continuous measurement of the length of the thread length unwound from the template 1. In order to control the speed of winding the thread, it is necessary to know as precisely as possible the length of the thread still on the spinning cop 1 at every moment of the winding operation.
  • the template 1, from which the thread 2 is withdrawn, is located in a first station 16 of the device, which is also called the main station here.
  • the spinning cop 1 shown in this main station 16 has a winding 19 which is on a sleeve 18 located. A certain length of thread 2 has already been drawn off from the winding 19 of this spinning cop 1.
  • This illustration of spinning cops 1 shows a possible state of the winding 19 during the operation of the present device.
  • This device is designed such that it also allows a spinning cop 1 to be introduced and processed in the main station 16, in which a section of the winding 19 has already been pulled off, in which the bobbin 19 has not been fully wound up, in which the Bobbin 19 has not been properly wound up or the like.
  • a further station 17 of the device which is also called a ballast station here, is connected upstream of the main station 16 mentioned.
  • This ballast station 17 is intended for the temporary reception of a further spinning cop 13. It is a spinning cop 13 which is exchanged for the empty tube 18 in the main station 16 after the thread 2 has been drawn off from the first spinning cop 1 in the main station 16.
  • this ballast station 17 there is a first load cell 12 on which the second template 13 rests. The output of this load cell 12 is connected to the control unit 8.
  • a further load cell 15 can be located in the main station 16, the first template 1 then resting on this second load cell 15.
  • the basic idea of this invention is to control the size of the rewinding speed in such a way that the thread tension remains as constant as possible while the thread is being pulled off a spinning cop, and that this thread tension is at the same time as close as possible to a limit above which thread breaks frequently occur.
  • the value of the thread tension which represents the mentioned tension limit, is an empirical value and is known for the respective thread type. It is also known that there is a direct between the thread speed and the thread tension there is a proportional ratio, ie the thread tension increases with increasing speed. In order to be able to achieve the object set in the present case, the control unit 8 must keep the thread speed, ie the take-off speed of the thread 2 in the range below the tension limit value and control it in such a way that the thread tension does not reach the tension limit value.
  • the diameter and the quality properties of the thread 2 to be rewound which are relevant in the present case, are known in advance or at least can be determined easily.
  • the weight of the sleeve 18 is also known in advance. From the weight of spinning cops 1 and 13, one can deduce the length of the thread to be wound. This weight is determined in the ballast station 17 by the load cell 12 and delivered to the control unit 8. This stores this weight until the start of the withdrawal of the thread 2 from the spinning cop 13.
  • the thread length meter 11 is set to zero at the beginning of the withdrawal of the thread 2 by a spinning cop 1, 13 and so on, and during the withdrawal of the thread, it continuously provides the information about the Length of the thread already drawn off.
  • the weight of the thread 2 located on the sleeve 18 is obtained. Since the quality characteristics of this thread 2 are known, the length of the thread can be deduced therefrom Winding 19 forming thread 2 are closed. The total length of the thread on a template 1 or 13 is calculated from the weight of the thread and a calculation factor length per thread weight. From the result of subtracting the length of the thread already drawn from the thread length meter 11 from the calculated total length of the thread on the winding 19, it is possible to deduce its remaining length. This remaining length is then for the control of the Rewinding speed by the control unit 8 is decisive because it indicates how far the rewinding has already progressed at the respective time and thus how great the thread tension may still be at the corresponding time.
  • the empty sleeve 18 is removed from the latter.
  • the next template 13 is brought from the upstream station 17 into the main station 16, the thread length sensor 11 is set to zero and the rewinding process can start based on the stored weight of the template 13.
  • the target thread tension can be program-controlled and changed depending on the remaining thread length still on the template 1.
  • the rewinding speed can be selected to be high during the first and longer phase of rewinding mentioned above and is only reduced towards the end of the rewinding process in order to prevent thread breaks from occurring in this phase. There is no increased number of thread breaks, even if the length of the thread 2 forming the winding 19 deviates significantly from the usual thread length in the winding 19.
  • the control unit 8 can also be designed in such a way that it enables the rewinding process to be optimized when a number of threads containing the same quality are spooled. This further possibility for increasing the production output is that the conditions of the rewinding process are optimized with an increasing number of rewound spinning bobbins. This can be achieved by detecting the length of the thread drawn from the first spinning cops and assigning it to the respective remaining length. Any thread breaks that occur are detected, for example by the thread length sensor 11, detected by the control unit 8 and assigned to that length or that length range the thread in which they occurred.
  • the speed with which the thread will be rewound in this length range during the treatment of the subsequent spinning heads is corrected. This correction is made against the lower yarn speeds if there were yarn breaks, and it is made upwards if there were no yarn breaks with this yarn length. With an increasing number of treated spinning cops, a better approximation to the mentioned limit tension in the thread can be achieved.
  • the total length of the thread can be divided into a number of partial lengths.
  • Each of these partial lengths is assigned a thread tension specification which resulted from the treatment of the preceding spinning cops. With this subdivision into partial lengths, the approximation to the tension limit in the thread is not optimal, but the expenditure on equipment in the rewinding device is less.
