Definitions
- the invention relates to a method for winding continuously, preferably at a constant speed, a thread-like winding material fed to a winding device in a stepped precision cross winding, in which the speed of the bobbin detects with a first sensor and the speed of the drive of the traversing thread guide with a second sensor, the speeds with each other compared and depending on which the drive of the traversing thread guide is regulated.
- Thread-like winding material is understood in particular to mean yarns or tapes.
- the winding direction for carrying out the method is provided with a drive for the bobbin and a first assigned sensor, with a drive for the traversing thread guide and a second assigned sensor and with a first controller for processing the signals of the two sensors for regulating the drive of the traversing thread guide.
- the speed of the bobbin and the number of double strokes of the traversing thread guide form a fixed ratio, the so-called bobbin ratio.
- the crossing angles necessarily change.
- changing the crossing angle is only possible within certain limits in order not to endanger the stability of the coil. Therefore the achievable diameter ratio between a full and an empty spool is limited.
- Precision cross-wound coils can but can be optimally adapted to the special requirements of the ware or its use.
- the change in the winding ratio from one stage of the precision cross winding to the next is so small that the change in the winding speed of the yarn caused thereby or ribbon 3%, preferably 0.3%, the mean wind speed does not exceed. This limits the change in wind speed. Due to the constant peripheral speed of the bobbin during the winding cycle, the change in the winding speed cannot be eliminated. This requires a very narrow gradation, so that the number of winding phases with a constant winding ratio increases. By an abrupt change in the coil ratio during the coil build-up in several phases, however, the crossing angle can be kept within limits that are favorable for the coil build-up.
- EP-OS 195 325 also assumes a constant spool circumferential speed when winding threads into packages and reduces the speed of the traversing thread guide between a predetermined upper limit and a fixed lower limit proportional to the decreasing spindle speed. When the lower limit is reached, the speed of the traversing thread guide is increased again up to the upper limit. This creates a precision cross winding with winding ratios reduced in stages. To improve the bobbin build-up, the upper and lower limits of the traversing speed are reduced or increased in the same direction during the winding cycle.
- EP-OS 194 524 also shows a method for winding threads in a graduated precision cross winding.
- the bobbin ratios not only have to be precalculated with great accuracy, but also have to be observed exactly. Since the electrical and electronic measurement and control technology, which are limited for the measurement of the speeds and compliance with the proportionality between the spindle drive and the drive of the traversing thread guide, the modulation of the winding ratio is proposed in each winding phase to improve the winding structure.
- the modulation width should be less than 0.1%.
- DE-AS 26 49 780 describes a winding machine for textile yarns in which the bobbin is driven on its periphery by means of a speed-controlled drive roller and the reverse thread shaft in which the traversing thread guide is moved is also speed-controlled. Both speeds are controlled by electronic control circuits and computers, which take into account, among other things, the mathematical relationships between winding speed, peripheral speed of the bobbin or drive roller and thread laying speed, so that the difference between thread speed and winding speed can be specified. With this device, the production of precision cross-wound bobbins with constant feed speed and constant thread tension during winding is possible.
- preprogrammed jumps in the winding ratio can be carried out on the computer in order to avoid unfavorable areas of the crossing angles when the bobbin is full and empty.
- the technical effort for these computer-controlled speeds of the drive roller and the reverse thread shaft is correspondingly high. Changes in the wind-up speed are not completely eliminated because a positive drive always slips.
- the invention is based on the object, starting from a method and a winding device of the type described above, that is to say in a graduated precision cross winding, to avoid the disadvantages which are associated with a constant coil peripheral speed.
- the drive of the bobbin is regulated in such a way that the winding speed of the winding material on the bobbin corresponds to the speed of the continuously supplied winding material during the entire winding cycle.
- the winding speed therefore remains the same not only in the individual winding phases with a constant winding ratio, but also during the jumps between the individual winding phases, that is to say in the time in which one winding ratio is left and the other winding ratio is sought.
- the new method is thus ideally suited for winding up items to be delivered continuously at a preferably constant speed, as is the case in particular with spun threads. This does not adversely affect the material to be wound. It always remains under a defined thread tension, so that all advantages of a stepped precision cross winding are achieved.
- the drive of the bobbin can be regulated by a thread tension transducer, in particular a dancer, in such a way that in every winding phase with constant winding ratio the decreasing winding speed caused by decreasing crossing angle is compensated for by a continuous increase in the speed of the bobbin, and that with every jump between two winding phases with constant winding conditions, the increasing wind-up speed caused by the increase in the crossing angle is compensated for by a reduction in the speed of the coil. So are the conditions by changing the crossing angle addressed. In addition, of course, the conditions that result from the increase in the diameter of the coil must also be taken into account. This influence is greater than the influence of changing the crossing angle.
- Each updraft phase can be started with a matching starting crossing angle and ending with a matching ending crossing angle.
- the crossing angle passes through a fixed, constant area in the area of each winding phase, which is decisive for the quality of the coil construction and the further processing properties of the coil.
- a winding device suitable for carrying out the method is equipped with a drive for the bobbin and a first assigned sensor, with a drive for the traversing thread guide and a second assigned sensor and with a first controller for processing the signals of the two sensors for regulating the drive of the traversing thread guide .
- a second controller for regulating the drive of the spool is designed in the sense of the winding speed of the continuously supplied winding material and is connected to the drive of the spool.
- the second regulator is preceded by a thread tension transducer, preferably a dancer, which adjusts the rotational speed of the drive of the bobbin in the sense of the winding speed of the continuously supplied winding material via this second regulator.
- the drive of the winding spindle is adjusted so that the z. B. the tension of the thread measured by the dancer arm remains defined.
- the drive for the coil can preferably consist of an axle drive. But it is also possible for Drive the coil to provide a drive roller, as is known per se.
- the sensors are usually designed as tachometers
- the sensors are now designed as pulse generators, with the computer each having a counter for each pulse generator.
- the speeds of the drives can be recorded exactly, that is, much more precisely than with a tachometer.
- a motor that can be regulated in its speed can be provided, which is preceded by a control device. It is also possible to provide a motor with adjustable speed for driving the traversing thread guide, which is preceded by a control device. In this way it is possible to determine the speed of the traversing thread guide as a function of the speed of the drive of the bobbin in accordance with the desired winding ratio, and on the other hand to regulate the drive of the bobbin in the sense of the winding speed of the continuously fed winding material, even with changing crossing angles, to reach.
- a three-phase motor 1 is illustrated in FIG. 1, via which the spindle 2, which is only symbolically indicated, is driven. It can be a direct axle drive or a drive roller drive.
- a pulse generator 3 is assigned to the three-phase motor 1, with the aid of which the speed of the spindle 2 or the three-phase motor 1 can be determined exactly.
- a three-phase motor 4 is provided, via which the traversing thread guide 5, which is only indicated, is driven.
- a second pulse generator 5 is assigned to the traversing thread guide 5 or the three-phase motor 4, so that its speed or rotational speed can also be monitored very precisely.
- Electrical lines 7 and 8 lead to a computer 9, each having a counter 10 and 11, a comparator 12 and a first controller 13.
- a second controller 20 is provided, which can be designed as a PID controller. With the counter 11, the pulses of the pulse generator 3 are counted. The counter 10 counts the pulses from the pulse generator 6. The number of pulses is further processed in the comparator 12 and fed to the first controller 13.
- a dancer 14 with a roller 15, over which the thread of the ware is passed, is connected upstream of the second controller 20.
- a movement of the dancer 14 leads to a signal change which is fed to the second controller 20.
- a first electrical line 16 leads from the second regulator 20 to the three-phase motor 1 via a regulator 17 designed as a frequency converter.
- the second regulator 20 primarily regulates the three-phase motor 1 and thus the drive of the spindle 2 in the sense of the winding speed of the continuously at preferably constant speed supplied laundry.
- an electrical line 18 leads from the first controller 13 via a control device 19 designed as a frequency converter to the three-phase motor 4 of the drive of the traversing thread guide 5.
- FIG. 2 shows a diagram to illustrate the constant length of winding material per unit of time (winding speed) wound up during the winding cycle.
- winding speed the amount of the length of the reels per unit time L is always constant.
- the circumferential speeds v U as well as the traversing speeds v C change with a constant winding ratio in each winding phase and nevertheless the length of the material to be wound per unit time L remains constant.
