Definitions
- the invention relates to the formation of bobbins, or, a method for operating a thread-winding machine and a winding device according to the preamble of claims 1 and 11
- one forms, for example, a step precision winding
- one starts per stage with a predetermined crossing angle, which decreases in the course of the step, that is with increasing diameter of the coil, and thereby decreasing speed of the coil and thus decreasing speed of the yarn guide.
- the speed of the thread guide is higher at the beginning of the step than at the end of the step, so that the following error is greater at the beginning of the step than at the end of the step and, accordingly, the spool width at the end of the step is greater than at the beginning of the step.
- a coil is formed with several stages, arises at the End faces of the coil, seen in cross section, an end face with SAgeierequerites.
- This sawtooth cross-section has the disadvantage that the thread layers have the tendency to slip over the end face against the bobbin tube, so that a so-called tension thread is formed, which leads to problems during further processing of the coil and is therefore undesirable.
- the invention solves the problem in that procedurally the following error, especially also jumps of the following error are corrected so that the end faces of the coil form a plane substantially.
- the method and the device is not dependent on the type of traversing method, that is, the method or the device can be carried out or executed each with a traversing device with a grooved drum or with wings or with a belt or with a traversing pointer.
- a Nutentrommelchangtechnik for example, in DE 26 27 643, viagelchang réelle in EP 0622 3-24 A.1 and Zeigerchangtechnik in DE 198 46 138.0 and in EP 0838 4-22 A.1 shown and described.
- Another traversing device by means of which the transfer point of the thread to the taching roller is variable, similar to that which is possible in the pointer shake, is shown and described in WO 00/17082.
- two counter-rotating discs are provided, on each of which three radially forward and backward sliding thread guides are arranged, which are arranged radially movable on the rotating disks and in each case in the corresponding Moment when taking over the thread before and on delivery of the thread are shifted back.
- FIG. 1 The figures 1, 2, 4, 8, 9 always the same, but provided with variations traversing device, wherein a figure number with an additional label "a” schematically the yarn path of a central yarn guide, to a traversing yarn guide in different positions and a pickup roller on a spool and a figure number with the mark "b" show the portions of the tacho roll and the bobbin surface contacted by the thread in the development. All figures 1, 2, 4, 9 and 10 show a semi-schematic representation of the traversing device and the differences between the figures are based on differences in the thread guide.
- FIG. 1 shows, with FIG. 1 a, a bobbin tube 1 on which a bobbin 2 with a thread F is formed.
- the thread F passes from any source (spinner or spool) through a central thread guide D and through a thread guide 4, which is shown here in the positions C.0 to C.3, to illustrate how the course of the thread from the central thread guide D takes place until the coil 2.
- the yarn guide stroke Hch extends from one end position C.0 to the other end position C.3.
- the thread can be dragged by the thread guide in the corresponding stroke direction, which means that the distance Hp between two reversal points (see also Fig. 2a) of the thread on a tachometer roller 3 is smaller than the yarn guide Hch.
- the so-called drag length between the thread guide and a thread take-up line 6 on the tachometer roller 3 is identified as a towing length 5.
- this length is indicated in the direction shown, although the exact length is basically greater due to the skew of the thread as shown in Figs. 1a and 1b.
- FIGS. 1a and 1b are semi-schematic representations, accordingly the point of emergence of the thread on the Coil in the figure 1b as a projection, while this is shown in the figure 1a as a development.
- FIG. 2 shows the position of the thread F in the two reversal regions of the traversing yarn guide 4, ie in position C.0 and C.3, ie in end positions with the corresponding following errors S, in position C4, ie in the neutral position without trailing error S and in the drag levels C.5 and C.6 in the reverse traversing direction. Further, in this figure 2a, the whole crossing angle ⁇ is shown, and also shown with the thread layers F.1 and F.2 in the front region of the spool 2, in which way the thread at the end of the traverse stroke, at least theoretically, placed on the coil becomes.
- FIG. 3 shows that with a larger crossing angle ( ⁇ 2 instead of 1), the following error S is also greater.
- FIG. 5a shows the velocity course Vch as a function of the time t of a thread guide 4 during the reciprocating stroke, but completely theoretically, since the change in the end points W takes place only with a finite delay or acceleration.
- the indicator 2Abw represents the development of the coil.
- FIG. 6 shows in the upper part the course of the crossing angle ⁇ with increasing coil radius R, that is to say a course between the crossing angles ⁇ 2 and ⁇ 1, during the construction of a step precision winding.
- the lower part of Figure 6 shows the in the course of de crossing angle ⁇ ( ⁇ 2 - ⁇ 1) resulting course of the drag error S, which means that with decreasing crossing angle also decreases the contouring error, which on the other hand, means that the coil width Hp at the same traverse stroke Hch thereby increases and thereby assumes the sawtooth shown in Figure 7.
- the stroke width Hch of the thread guide or the transfer points of the thread through the radially displaceable yarn guide at the stroke ends such adapt that the coil width Hp remain constant despite tracking errors and jumps in the following error, so that the aforementioned sawtooth profile shown with the figures 6 and 7 can be avoided.
- Figures 8 and 9 each show a variant to avoid said sawtooth structure.
- Figure 10 shows schematically a control for carrying out the invention by means of traversing devices, as mentioned above.
- the box 8 shows an operating data input, that is, an input 10 for the crossing angle ⁇ and an input 11 for the stroke width Hp in a correction computer 9 with a target hub computer 13, an interpolation computer 14 and a following error table 15th
- the input 10 in the interpolation computer 14 and the input 11 in the target hub computer 13 In addition to the interpolation computer 14 is the following error table 15, and the interpolation computer 14 outputs its signal 12 as a following error input to the target hub computer thirteenth This adds the values "11" and "12" and calculates the signal 16 as yarn guide stroke width Hch and outputs this width in a traversing system 17, which corresponds to one of the aforementioned traversing systems.
- the correction calculator receives the value for the desired stroke width Hp (width or length of the spool). To do this, it adds the calculated following error and thus forms the setpoint "stroke width Ch" for the traversing system.
- the traversing system must now be able to actually comply with the "stroke width Ch" setpoint. This happens depending on whether the reversing point of the thread guide, the location of the thread transfer or the drag length is changed with the traversing system and that depending on a suitable aforementioned traversing system.
- the resulting coil has a constant stroke width Hp with this method even with changing crossing angle and thus no sawtooth structure as shown in FIGS. 7 and 8.
- This method is able to determine the associated following error without delay in the case of jumps in the crossing angle (as required for step precision winding, for example).
- the traversing system then receives a setpoint jump for the stroke width Hch. If the traversing system can now follow this setpoint step without delay, coils with flat faces (no sawtooth structure) are formed.
