Description


  The present invention relates to a method for winding a thread on a bobbin tube to a cross-wound bobbin, wherein the mounted in a creel cheese is driven by a single motor driven device and the thread is laid on the cross-wound bobbin by means of a motor driven individually traversing.

  

From the patent application DE 3 533 112 A1 it is known that it is complicated when transporting finished, cylindrical cheeses on a double-sided, cross-wound textile machine, to take into account the different winding directions of the produced on different sides of the machine cheeses to difficulties when pulling the thread over the head of the cheeses to avoid. The cylindrical cheeses can not be viewed purely externally the winding direction. Thus, in ignorance of the winding direction, a cross-wound can be deducted on the foot side during further processing instead of overhead.

   By the opposite deduction direction of the thread rotates in different directions, namely clockwise, so the so-called P-direction respectively P-turn or counterclockwise, the so-called Q-direction or Q-turn.

  

The threads themselves have a twisting direction, which was impressed upon them during spinning, namely Z-wire or S-wire. During unwinding, it has been found that Z-twisted yarns perform better when running downwind in P-turn, while S-twisted yarns run better when running downwind in Q-turn. In the opposite direction of removal, the threads continue to rotate, causing protruding fibers of the adjacent or underlying thread layers are screwed in and cause a kind of velcro effect. Therefore, it is important in cylindrical coils to distinguish the head side of the foot side, so that not by peeling over the foot end of the thread breakage number is increased.

   Therefore, the production speed has been reduced even when S-twisted yarns have been removed, thereby reducing thread breakage. Now it would also be possible, although not known from the prior art, to unwind cylindrical cheeses which are spooled with a yarn having S-wire, deliberately from the foot side. For this purpose, it would be necessary to exclude confusion, which should be difficult for cylindrical coils due to their symmetrical structure. A wrong unwinding direction would lead to frequent yarn breaks in the case of the high unwinding speeds due to the assumed unwinding direction.

  

In principle, the flow behavior of conical cheeses is particularly suitable for high take-off speeds, the thread must be deducted after the end of the smaller diameter in order to avoid as possible the touch of the coil edge. Since in the prior art, the taper is produced only in one direction, which is optimal for Z-twisted yarns, a reduction in the take-off speed is always necessary for S-twisted yarns.

  

From the generic patent application EP 1 702 876 Al a method is known in which for winding a yarn to a cheese on a bobbin, a held in a creel spool bobbin is frictionally driven by a single motor driven roller, while the thread to the coil structure is moved on the bobbin tube by means of a single motor driven drifting device. The creel is movably mounted about a pivot axis, so that the creel frame can change its position with increasing diameter of a cylindrical cheese in the vertical direction.

   In addition, for producing conical cheeses, the coil frame has another pivot axis arranged orthogonally to the pivot axis in order to adapt the position of the frame to the conical shape of the cross-wound bobbin with the increasing diameter of the conical cross-wound bobbin.

  

The object of the present invention is to provide a method for winding a yarn to a cross-wound bobbin on a bobbin by which the optimal for unwinding deduction direction in response to the Garndrehungsrichtung is made possible in a simple manner and a suitable for performing the method winding device propose.

  

This is achieved according to the invention in terms of the method in that for controlling the single-motor drive of the traversing device, a so-called Konizitätsfaktor is used, which reproduces the ratio of the yarn laying speeds at the end faces of the cheese, wherein on the cylindrical bobbin depending on the Garndrehungsrichtung the Konizitätsfaktor is raised or lowered starting from the value 1 during the spool travel of the cross-wound bobbin, wherein on the creel is adjusted with the by changing the Konizitätsfaktors asymmetric yarn order at least in their direction matching Zusatzkonizität by which the creel is inclined to the horizontal to the conical Structure of the cheese to follow.

   The inventive method allows the construction of conical cheeses, which are deducted according to their Garndrehungsrichtung generally on the side of the smaller cheese diameter, so that both S-wire and Z-wire wound packages can be further processed with the highest possible take-off speed. The change of the conicity factor during the winding of S-wire to a cheese causes a conical cheese to be formed on the cylindrical bobbin, in which the head side is formed as the side with the larger bobbin diameter and the foot side as the side with the smaller bobbin diameter ,

   The cross wound bobbin wound up in accordance with the invention is forcibly removed on the foot side in the subsequent process of further use, since the cross bobbin is pushed onto a gate or the like in accordance with its shape with the head side first. In this way, the unwinding is effected on the foot side, which leads to the avoidance of thread breaks, which, as known from the prior art, would result in ignorance of the winding position of the thread at high take-off speeds. Conversely, the change in the Konizitätsfaktors during the winding of Z-wire to a cross-wound bobbin, that the process according to the wound on a cylindrical bobbin cheese cross is always deducted overhead, since this side is the one with the smaller bobbin diameter.

  

In particular, by the Konizitätsfaktor and the Zusatzkonizität the cheese are formed so that the side with the smaller diameter over which the cheese to be unwound, has such a position that the yarn is twisted when unwinding in the direction of turning in itself , The tendency of the withdrawn yarn to pinch off trailing fibers of adjacent or underlying thread layers when pulled in the winding direction where the thread continues to be twisted, is reduced.

  

Preferably, the Konizitätsfaktor from the beginning of the coil travel can be changed. As a result, density differences in the coil structure are avoided, which are due to punctual changes in the contact pressure with the increase of the diameter during the coil travel.

  

In particular, the Konizitätsfaktor can be changed in dependence on the angular position of the coil frame. Since the continuous change of the angular position of the bobbin frame over the increase of the diameter of the cross-bobbin influences the bobbin construction with respect to the density distribution in the cross-wound bobbin, the conic factor is accordingly lowered over the bobbin winding in order to achieve a balanced material application on the cross-wound bobbin, which is necessary for a uniform bobbin construction is.

  

Preferably, the change in the Konizitätsfaktors during the coil travel can be carried out continuously, so that a sliding decrease of the Konizitätsfaktor is effected. However, the calculation of the ideal curve of the change in the conicity factor is computationally intensive.

  

Alternatively, the Konizitätsfaktor can be changed in discrete steps, whereby the computational effort during the spool trip is reduced.

  

In particular, the number and length of an interval between the discrete changes in the Konizitätsfaktors depending on the desired overall diameter of the cheese to be produced can be determined. Since the overall diameter of cheeses to be produced may vary from lot to lot, it makes sense to individually adjust the respective number of and the length of an interval between the discrete changes in the conicity factor to the respective desired total diameter of the cheese to uniform coil construction for each cross-wound bobbin guarantee.

  

For this purpose, the Konizitätsfaktor depending on the desired taper of the cheese can be lowered to a value up to 0.5. The conicity of the cheese to be produced can be specified at a central control unit in order to lower the Konizitätsfaktor during the Spulenreise starting from the initial value of 1 depending on the predetermined conicity. For example, with a preset taper of 4 [deg.] 20, the conicity factor is lowered in the course of the coil travel to a value of about 0.8 to 0.85. For example, in a cross-wound bobbin having a taper of 5 [deg.] 57, the conicity factor is lowered to a value of about 0.7 to 0.75.

  

Preferably, at least one curve of the change in the Konizitätsfaktors be deposited in a central control unit, which is retrievable for the production of cheeses of a certain conicity. This achieves a further simplification by selecting at the central control unit from a plurality of selectable curves the change in the conicity factor which is adapted to the parameters and shape of the conical cheese to be produced.

  

To carry out the method, a winding device is proposed, which has a traversing device, which is driven by a motor single motor, and a bobbin drive roller for frictionally driving a content Erten in a pivotally mounted coil frame cross wound coil, wherein for controlling the respective single-motor drive of the work stations Konizitätsfaktor the Spulstellenrechner is specified, and on the creel an adjusting device is arranged, by the tilting of the creel to the left or right with its conditional by the growth of the cheese spool can be specified and an inclination angle is adjustable to the creel during the winding process to the horizontal is inclined.

   By means of the adjustment device, the required conicity of the finished cross-wound bobbin can be predetermined for producing conical cheeses, by corresponding to the desired conicity of the finished cross-wound bobbin on the device, starting from a center position corresponding to 0 [deg.] And can be spooled in the cylindrical cheeses Angle is adjustable. In addition, the adjustment device alternatively allows tilting of the creel to the left or right to wind a left-handed or right-handed thread on cylindrical bobbins to conical cheeses.

  

The invention is explained in more detail with reference to an exemplary embodiment shown in the drawings.

In Fig. 1 is a side view schematically a job 2 of a cheese-producing textile machine, in the embodiment, a so-called cheese package 1, shown. On the workstations 2 of such automatic packages 1 spin rolls produced on ring spinning machines, relatively little filament material having 3 rewound to large-volume cheeses 5. The cheeses 5 are transferred after their completion by means of a not shown, automatically operating service unit on a machine-length cross-bobbin transport device 7 and transported to a machine end side Spulenverladestation or the like.

  

Such automatic packages 1 also generally have a logistics device in the form of a cop and tube transport system 6. In this cop and sleeve transport system 6, the spinning cops 3 or empty tubes run on transport plates 11. From the cop and sleeve transport system 6 in FIG. 1, only the Kopfzuführstrecke 24, the reversibly driven storage section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 27 are shown.

  

Each workstation 2 of the automatic winder 1 has a control device, a so-called winding station computer 28, which, inter alia, via a bus connection 29 to a central control unit 30 of the automatic winder 1 and via control lines 15, 35 to the individual drives 14, 33 of a winding device connected.

  

The winding device 4 has inter alia a coil frame 8, which, as indicated in Fig. 1, at least about a pivot axis 12 which is parallel to the axis of rotation of the cheese 5, is movably mounted. The coil frame 8 can also, what is basically known and therefore not shown for reasons of clarity, to a further pivot axis which is orthogonal to the pivot axis 12, limited to be rotatably mounted. The creel 8 is designed so that either cylindrical or conical cheeses can be wound on it.

  

As further indicated in Fig. 1, the freely rotatable held in the creel frame 8 cheese 5 during the winding operation with its surface on a bobbin drive roller 9, which is acted upon by an electric motor 33 single motor. The electric motor 33 is connected via the control line 35 to the workstation computer 28.

  

Furthermore, a traversing device 10 is provided for traversing a thread 16 during the winding process. Such, in Fig. 1lediglich schematically indicated traversing device 10 preferably has a finger thread guide 13 which acted upon by a reversible single drive 14, traversing the thread 16 running on the cheese 5 at high speed between the end faces of the cheese 5. The yarn guide drive 14 is also on the control line 15 to the workstation computer 28 in connection.

  

Fig. 2 shows schematically the winding device 4 a job 2 in a perspective front view. As indicated, each of these jobs 2 has a winding station housing 31 equipped with an input device 32, which accommodates, among other things, the winding station computer 28. At the winding unit housing 31, the winding device 4 is also set, which consists essentially of the creel 8 for holding a cylindrical sleeve 18, the bobbin drive roller 9 for rotating the sleeve 18 and the forming thereon cheese 5 and the traversing device 10 for traversing the cross-wound bobbin running thread 16 is.

  

The traversing device 10 has a finger thread guide 13, the single drive 14 is connected via the control line 15 to the winding station computer 28. The finger thread guide 13 can be controlled via the winding station computer 28 so that inter alia the thread laying speed can be set exactly.

  

The bobbin drive roller 9 also has a single drive 33, which in turn is connected via the control line 35 to the winding station computer 28 in connection to drive the single drive 33 defined. The coil frame 8, which is mounted rotatably limited to at least one pivot axis 12, has two coil frame arms 20, 21, which in turn are each equipped with a rotatably mounted sleeve receiving plate.

  

In Fig. 3, the coil frame 8 and the adjusting device 36 arranged thereon for adjusting the Zusatzkonizität is shown. The additional conicity is set before the start of the coil travel in order to achieve the desired conicity at the end of the coil travel with the achievement of the nominal diameter of the cross-wound bobbin 5 to be produced. The additional conicity set on the setting device 36 causes the coil frame 8 to be forcedly guided. The setting device 36 comprises a carrier 37 by means of which the setting device 36 is fastened to the housing of the workstation 2. Furthermore, a lever arrangement 40 is provided which is articulated on the coil frame 8 and on the carrier 37. One arm of the lever assembly 40 is slidably disposed in an arcuate slot 38 while another arm is hinged to the creel 8.

   To set the required additional conicity, a scale 39 is provided on the carrier 37 above the slot 38 in order to be able to set an angle corresponding to the desired conicity of the cross-wound bobbin. The additional conicity is adjusted and fixed along the slot 38 by the displacement of an adjustment aid 41, which is connected to the lever arrangement 40. For this purpose, the setting aid 41 is moved in the slot 38 to the left or to the right before starting the winding, starting from a center position which corresponds to an additional conicity of 0 [deg.], And then fixed in this position.

  

In the middle position of the adjusting device 36, the coil frame 8 is pivoted only parallel to the coil drive roller 9, so that cylindrical cheeses are produced. The setting of a Zusatzkonizität on the adjuster 36 left of the center position, as shown in Figure 3, causes the lever assembly 40 raises the coil frame 8 in the course of the coil travel and tilted to the right, while at a set Zusatzkonizität right of the center position of the coil frame 8 through the lever assembly 40 is tilted to the left.

   The adjustability of Zusatzkonizität carried out on the adjusting device 36 by means of the scale 39 in discrete steps, starting from the center position for the production of cylindrical cheeses, to an adjustment to the left for winding right-handed thread or to the right for winding from left-handed thread to conical cheeses.

  

For winding of rechtsgedrehtem thread to a conical cheese 5 on the cylindrical sleeve 18, a curve of the Konizitätsfaktor K is determined by the winding station computer 28 or predetermined by this, which reproduces the ratio of the yarn laying speeds at the end faces of the cheese. For the construction of the conical cross-wound bobbin 5 on the cylindrical sleeve 18, a Konizitätsfaktor equal to 1 is given as the initial value, in which the ratio of the thread laying speed at the end faces is constant, which corresponds to the Konizitätsfaktor for the construction of a cylindrical cheese.

   According to the invention, however, from the beginning of the spool travel on the Konizitätsfaktor K is lowered continuously until the Konizitätsfaktor K has been lowered to a final value, so that the structure of the cheese 5 at the end of the spool travel of the desired taper corresponds. The change in the Konizitätsfaktorors K ideally has a linear curve, which is dependent on the diameter increase on the cheese 5 and thus the angular position of the coil frame 8, as shown in Fig. 4 exemplified.

  

A second curve of the Konizitätsfaktorors K, as exemplified in Fig. 5, is substantially stepped, which is due to the changes in the Konizitätsfaktorors K in discrete steps. The coil frame 8 must be inclined in the course of the coil travel at an angle to the horizontal in order to follow the conical structure of the cheese 5 can. The change in the angular position of the coil frame 8, as already described, slidingly forcibly guided by the adjusting frame 36 arranged on the coil frame 8 for generating the Zusatzkonizität.

  

The change in the Konizitätsfaktorors K takes place according to the method in dependence on the change in the angular position of the coil frame 8. For this purpose, a continuous reduction of the Konizitätsfaktor K be provided, as indicated by the linear curve in Fig. 4. Alternatively, the lowering of the conicity factor K is stepwise as shown in Fig. 5. The gradual reduction can be achieved with less computation than the continuous reduction of the conic factor. K. In addition, it is possible in the central control unit 30 to deposit a multiplicity of gradients of the change in the conicity factor K, which have been predetermined for the respective desired conicity of a cross-wound bobbin and which can be selected by an operator.

   The shift of the Konizitätsfaktorors K occurs, for example, for a cheese with the taper 4 [deg.] 20, starting from the value 1 to a final value of about 0.8 to 0.85. In the case of a cheese of conicity 5 [deg.] 57, the value is lowered to about 0.7 to 0.75, with a larger angle of the additional conicity preset by means of the adjusting device 36 relative to the cheese with the taper 4 [deg.] becomes. The inventive method is suitable in a corresponding manner for winding of left-handed thread on a cylindrical sleeve 18 to a conical cheese 5.
