Definitions
- the invention relates to a winding machine according to the preamble of claim 1.
- This winding machine is known from DE-OS 39 33 048 (Bag. 1659).
- a winding machine for winding a thread is known from which the dancer arm is connected to a potentiometer so that a Change in position of the dancer arm to a direction-dependent change in tension on Potentiometer leads.
- This potentiometer voltage is used as a position measurement for an ID controller given to generate a signal to adjust the spindle speed.
- the disadvantage of this known winding machine is that the control the sudden changes in position due to the oscillating movements to vibrations the spindle speed and thus lead to an uneven coil build-up.
- the object of the invention is the winding machine with its To design the control system so that the control system is able to all fluctuations in the position of the dancer arm without switching to compensate for those fluctuations caused by the back and forth movements of the traversing device become.
- controller is programmable and adjustable over a wide range is, so that all operating states are recorded and in discrete Control values can be implemented and that the control the occurring operating conditions can be adjusted sensitively, the extreme conditions - such as B. creating and Starting off - no switching required.
- a precision cheese head is in perspective shown.
- Fig. 2 shows diagrams to illustrate the Measuring and control procedure.
- Such precision bobbins are in several horizontal and vertical rows side by side in arranged a precision cheese winder.
- the precision cheese head is in a vertical Stand plate 1 arranged.
- the Spool 3 On the stand plate 1 is the Spool 3 on which the spool with the winding tube is stretched, cantilevered.
- the winding spindle 3 is the Traversing device for traversing the incoming thread 12 assigned.
- the traversing device is parallel to the coil from the housing 11, in which a reversible thread shaft 10 is rotatable is stored, and that of the reverse thread shaft in one Straight guide back and forth traversing thread guide 9, the Thread 12 laid on the bobbin.
- a support roller 28 on the housing 11 of the Traversing device freely rotatable.
- the traversing device with the reverse thread shaft is on one Carriage 13 attached.
- the carriage 13 is in one Carriage guide 14 mounted, which is a linear movement - radial or secantial to the coil - allows.
- a spring 15 acts thereby on the carriage in such a way that the traversing device against each other with their support roller 28 during the entire winding cycle the coil surface supports, but the growing Diameter of the coil 2 can dodge.
- the fed thread 12 runs before it from the traversing thread guide 9 is laid on the coil surface, over two fixed Rollers 5 and 6, between which a dancer arm 7 with a Dancer roll 29 is pivotally arranged.
- the dancer role lies under the weight of the dancer arm on the thread.
- the drive motor 4 for driving the Spool spindle 3 attached.
- This drives over one Timing belt pulley 31 and timing belt 32 one on this side of the Stand plate cantilevered end of the winding spindle 3 non-rotatably arranged toothed belt pulley 33 and thus the Central winding spindle 3.
- the winding spindle is with the Reverse thread shaft 10 connected by gear Toothed belt pulley 16 and toothed belt 19 and toothed belt pulley 18 with a countershaft 30 and from there by another Toothed belt pulley 26 over toothed belt 20 and toothed belt pulley 17th with the reverse thread shaft 10.
- the countershaft 30 is opposite the winding spindle 3 and opposite the reversing thread shaft 10 by each a pivot lever 23 and 22 supported and in the free ends this pivot lever is rotatably mounted.
- the thread runs at a constant speed. This forms between the thread guides 5 and 6 due to the constant Weight of the dancer arm 7 with the dancer roll 29 - possibly reinforced by a spring - a sag.
- the size of this Sag is determined on the one hand by the Feed speed of the thread and the other through the Winding speed. The size of this slack will increase adjusted a constant value. However, the Fluctuations caused by the traversing movement be allowed.
- the axis of the dancer arm is with a Control device 8 connected. Through the control device 8 the drive motor 4 controlled. If the sag of the Fadens enlarged and consequently the dancer arm 7 clockwise pivots, the drive speed of the spindle motor 4 is increased. If the sag decreases, the drive speed increases reduced.
- the dancer arm 7 and the control device 8 are So included in a control loop through which the sag of the Thread loop between the thread guides 5 and 6 is corrected.
- control of the drive motor 4 is designed so that that the following functions are performed:
- the thread is first placed over the thread guide 5 and 6 led and wrapped around the dancer roll 29.
- the string is then placed on the empty tube and by the rotating Empty sleeve caught.
- the dancer arm 7 lifts off from its lower stop position and switches from the applied speed controller 37 to the Switch 34 on the dancer arm to the dancer arm control 38.
- the dancer arm with the rotating roller 29 is provided with a rotation sensor 40 connected.
- the position and the Speed of the dancer arm detected. It can become Example is a magneto-resistive sensor.
- This magneto-resistive sensor has a fixed ferromagnetic Layer that is enclosed in a circuit. On this ferromagnetic layer acts on a magnet, which with the Dancer arm is rotatable. By changing the rotational position of the Magnetic field also changes the electrical resistance of the ferromagnetic layer so that the voltage drop across the ferromagnetic layer a measure of the rotational position of the dancer arm is.
- the Speed of the dancer arm In addition to the position of the dancer arm, the Speed of the dancer arm, depending on height and direction, measured. For this purpose, the measurement is carried out at predetermined time intervals repeated and the speed determined from this. The ongoing determined measured position values and the measured speed values are now given to the controller.
- the controller has a memory with different Storage areas.
- position quantity areas saved in the position storage area. These position quantity ranges are shown in Fig. 2A.
- the quantity areas define a membership value with which a determined position measurement value for the previously defined position quantity range heard. These membership values are in on a scale from 0 to 1.
- Each quantity range is divided into a main area and a transition area. By doing The main area has a membership value of 1.
- the membership value falls to the respective neighboring quantity range drops from 1 to 0, whereby however overlaps to the neighboring transition area occurrence.
- the Transition area Ib of quantity area I covers all Measured values that are only limited to the quantity range can be assigned "far below".
- the memory also has a memory area in which as Control algorithm any occurring combination of position quantity ranges and speed quantity ranges a certain manipulated variable quality range according to FIG. 2C assigned.
- the membership value (fulfillment value) of the Control value for the selected quantity range II for example by multiplying the membership values for position and Speed to their respective candidate Quantity range. Before this multiplication or other superposition also a weighting of Affiliation values are made that reflect the level of trust of the Affiliation reflects.
- the result is the fulfillment value.
- the weighting factor (measure of trust) for both membership values 1. This results in the Affiliation value (fulfillment value) for the manipulated variable to his selected quantity range with also 0.8.
- FIG. 2C shows that this means that the manipulated variable quantity range II "negative medium" those below the 0.8 horizontal area indicates the area from which the Control value is selected.
- the computer also contains one for this Rule algorithm.
- This control algorithm can, for example state that the manipulated variable is the abscissa of the centroid is the area covered by that Quantity range cut off by membership value becomes. This area is hatched in Fig. 2C.
- the abscissa of the Center of gravity and thus the manipulated variable has the value -3. This Value is given to the motor to reduce the speed.
- the measured position value is in contrast 3 measuring units.
- the computer takes these control algorithms from the total of 15 control algorithms from the memory and accordingly assigns the manipulated variable quantity ranges II and III to the current measured value. This is shown in Fig. 2D.
- the membership value of the manipulated value to the respective quantity range results from the membership values of the measured value to the assigned position or speed quantity ranges by superimposition as previously described.
- the computer is now programmed so that it can Center of gravity of the area determined which the selected limited by the respective membership values Cover quantity ranges; d. h .: the overlapping Area is only calculated once, the rest is the sum of Quantity ranges formed by the assigned Membership values are limited.
