Definitions
- the invention relates to a method and a device for operating a winding device of a cross-wound textile machine according to the preamble of claim 1.
- Such thread laying devices with a traversable thread guide are known in numerous embodiments and, for example in the DE 37 25 812 A1 , of the DE 199 60 024 A1 , of the EP 0 453 622 B1 or the U.S. Patent 4,771,960 described in detail.
- the thread deposited on the lateral surface of the cross-wound bobbin in each case describes a radius in the region of the coil flanks, which leads to the construction of elevated coil flanks. That is, in the areas of the coil flanks of the cheese, in which the direction of movement of the thread guide is reversed (reversal distance), significantly more yarn is deposited than in the Areas where the thread guide moves at a constant speed. It comes therefore, if no special measures are taken, in the region of the coil flanks of the cheese to material accumulations.
- the changes of the traverse stroke take place in a range which is determined by a maximum traverse stroke and a minimum traverse stroke.
- the successive traverse strokes are changed such that after a shortened traverse stroke an extended traverse stroke and after a prolonged traverse stroke again a shortened traverse stroke. In this way, a stable coil structure without saddle formation in the region of the coil edges is achieved.
- the radius which the deposited thread describes on the lateral surface of the cross-wound bobbin in the region of the coil flanks is responsible for the structure of the coil flanks.
- This so-called reversal radius is determined by the acceleration of the thread guide, the peripheral speed of the coil and the distance between thread guide and storage point of the thread on the spool and not only affects the mass distribution in the cheese, but is also a major factor in the formation of so-called tees the coil edges.
- Such deductions hinder the proper course of the thread from the cross-wound bobbin and thus represent an unacceptable quality defect of the cheese.
- the radius of inversion of the thread especially in the field of Spool flanks of the cheese to keep below a limit, which in turn depends on other textile parameters. For example, since the distance between yarn guide and storage point of the thread are set on the spool, the only way to reduce the radius of inversion is to increase the acceleration of the yarn guide.
- the known methods are based on the well-known fact that in the manufacture of cheeses on high-speed winder the traversing of the thread in each case essentially from a short acceleration phase after the one reversal point, a movement at a constant speed in the middle of the coil and a short delay phase before the other reversal point.
- the acceleration and deceleration values of the thread are very high at reversal points, since the thread laying, depending on the process control, with frequencies of up to 30 Hz.
- the EP 0 453 622 B1 a method or a device is known, which / allows a high acceleration of the thread guide at the reversal points and at the same time is very flexible with respect to the structure of the winding of the cheese.
- the drive of the thread guide is, while the thread guide is near a reversal point, acted upon by a motor current which is above the rated current and supplies in the remaining area with a motor current which is below the rated current.
- the applied by an electric motor drive such as a DC motor
- the acceleration of the thread guide behaves proportional to the supplied motor current.
- the power loss of such an engine which is released primarily in the form of heat, is proportional to the square of the motor current.
- the power loss occurring in the acceleration phases of the yarn guide is responsible for a large part for the thermal load of the drive. Since such electromotive drives must be dimensioned according to their thermal capacity, thus determines the reversal acceleration of the yarn guide essentially the size and thus the manufacturing cost of the motor to be used.
- this statement does not apply to every single acceleration phase, but because of the large time constant in the heating of the motor for the average of the power losses resulting in the acceleration phases.
- the present invention seeks to provide a method and an apparatus that allows a cost-effective dimensioning of an electric motor thread guide drive a winder, without affecting the quality of the cheese to be produced is adversely affected.
- the inventive method has the particular advantage that the average thermal load of the thread guide drive can be significantly reduced by the special control technology link the width of the traverse strokes with the acceleration of the thread guide. That is, with the method according to the invention, it is possible with a relatively small drive there to realize relatively high acceleration values of the thread guide, where these acceleration values are required, but at the same time to ensure that despite the use of a small and therefore cost-effective drive, this thread guide drive in the Continuous operation is not thermally overloaded.
- the drive of the yarn guide is briefly applied to traverse strokes whose reversal points in the coil flanks of the cheese to achieve maximum acceleration with a motor current of 3 to 6 times, preferably 4 times, the thermally for a permanent operation of the drive permissible motor current.
- the motor current supplied to the thread guide drive is approximately 1.5 to 2.5 times, preferably 2 times, the motor current permissible for permanent operation of the drive. Since a large number of the traverse strokes to be executed during a spool travel are shortened traverse strokes with reduced acceleration of the thread guide and correspondingly reduced power loss of the thread guide drive, the mean value of the power losses governing the thermal loading of the electromotive drive remains within technically controllable limits.
- two acceleration values for the yarn guide can be set via the control device. That is, a first maximum acceleration value, when a full traverse stroke is traveled, the reversal points are in the range of the coil edges of the cheese, and a second, reduced acceleration value at shorter traversing strokes.
- a first maximum acceleration value when a full traverse stroke is traveled, the reversal points are in the range of the coil edges of the cheese, and a second, reduced acceleration value at shorter traversing strokes.
- control device becomes somewhat more complicated if, as described in claim 3, except with a maximum acceleration value for full traverse strokes, with a
- An optimization of the coil structure can be achieved if a continuous adjustment of the acceleration values of the thread guide takes place by the control device (claim 4). That is, if in each case depending on the width of the Changierhubes the thread guide a continuous adjustment of the acceleration value of the thread guide takes place.
- the device described in claim 5 for carrying out the method according to the invention comprises a coil frame for rotatably supporting a coil, an electric motor acted upon thread guide and a control device for the defined driving the thread guide drive.
- the control device is designed so that the yarn guide drive, only when a full traverse stroke is to be executed, maximally accelerated. This means that the drive is then briefly subjected to a motor current which is 3 to 6 times, preferably 4 times, the motor current permissible for a permanent operation of the drive.
- control device ensures that the supplied motor current is reduced by about half, which immediately has a significant effect on the power loss of the drive.
- the drive is briefly acted upon by a motor current which is 1.5 to 2.5 times, preferably 2 times, the thermally permissible for a permanent operation of the drive motor current, whereby the thermal load of the thread guide drive immediately decreases significantly.
- the thread guide is formed in an advantageous embodiment as a finger thread guide and pivotally mounted about an axis which is substantially perpendicular to the axis of rotation of the cheese.
- the thread guide drive is preferably designed as an electric motor single drive.
- Such finger thread guides are characterized in particular by a relatively low weight, which is very important in view of the fact that such thread guides are oscillated by the electromotive single drive with a frequency of about 30 Hz.
- the winding device indicated overall by the reference numeral 1 has a coil frame 2 for rotatably supporting a cross-wound bobbin 3. That is, between the coil frame arms of the creel 2, as usual, a cross-wound bobbin 3 rotatably mounted, which rests with its surface on a drive roller 5 and is driven by this drive roller 5 via frictional engagement.
- the drive roller 5 is connected for this purpose to a single electric motor drive 6, which in turn is connected via a control line 21 to a control device 10.
- the cheese 3 frictionally driving drive roller 5 of course, also another drive type is conceivable for rotating the cheese 3.
- a spindle drive is then preferably arranged at the height of the axis of rotation 4 of the cross-wound bobbin 3 on the creel 2.
- a special thread laying device For traversing the running on the cheese 3 thread 9, which is unwound from a supply spool, preferably from a spinning cop, not shown, a special thread laying device is provided.
- the yarn laying device has a changeable yarn guide, for example, a finger yarn guide 7, which is mounted rotatably limited about a pivot axis 20 and by means of an electric motor drive 8, preferably a DC motor, defined pivot.
- the electric motor drive 8 is connected for this purpose via a control line 11 to the control device 10.
- an angle sensor 23 is also attached, which is also connected via a signal line 24 to the controller 10.
- the maximum pivoting paths of the yarn guide 7 during a double stroke are in the Fig. 1 indicated by R and L, respectively.
- FIGS. 2 and 3 schematically a thread tray on the surface of a cheese 3 is indicated.
- the cheese 3 is shown in each case in the upper part of the drawings.
- the Fig. 2 shows the situation with a so-called "full” traverse stroke. That is, in a traverse stroke whose reversal points 14 each lie directly in the region of the coil edges 15 of the cheese 3. In such a “full” traverse stroke of the yarn guide 7 is accelerated from its reversal point 14 each maximum.
- Such "full" traversing strokes therefore indicate, as in Fig. 2 indicated, each having a relatively short acceleration region 12. At this acceleration region 12 is followed by a much longer center region 13, in which the speed of the yarn guide 7 is largely constant.
- the acceleration of the yarn guide 7 at a shortened traverse stroke is significantly lower, which has an extremely positive effect on the thermal load of the drive 8. That is, in a traverse stroke, the reversal points 14 are spaced from the coil edges 15 of the cheese 3, there are acceleration regions 12 and deceleration regions 22, which are slightly longer than at maximum acceleration and thus to larger reversing radii of the running on the cheese 3 thread 9 lead at the However, such a reduced acceleration occurring power loss of the drive 8 is significantly smaller.
