Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • This winding machine is known for DE-OS 39 33 048 (Bag. 1659).
  • US-A-3713009 is a winding machine known for winding a thread, in which the dancer arm connected to a potentiometer in this way is that a change in position of the dancer arm a directional voltage change on the potentiometer leads.
  • This potentiometer voltage is called Position measurement given up to an ID controller Generate signal to adjust the spindle speed. This ensures that sudden changes in position of the dancer arm are adjusted accordingly.
  • the disadvantage of this known winding machine is in that the regulation of sudden changes in position due to the oscillating movements to vibrations the spindle speed and thus to an uneven Lead coil build.
  • the object of the invention is the winding machine with their rules so that the Regulation is able to withstand all fluctuations in position to adjust the dancer arm without switching, and also those fluctuations which through the back and forth movements of the traversing device are caused.
  • the controller in wide ranges is programmable and adjustable so that all operating states recorded and converted into discrete control values can be and that the scheme the occurring Operating conditions can be adjusted sensitively can, whereby the extreme conditions - such. B. putting on and moving off - no switching required.
  • a precision cheese head shown in perspective.
  • Fig. 2 shows diagrams to illustrate the measurement and control process.
  • Such precision bobbins are in several horizontal and vertical rows side by side in one Precision cross winding machine arranged.
  • the precision cheese head is in one vertical stand plate 1 arranged.
  • the winding spindle 3 On the stand plate 1 is the winding spindle 3, on which the coil is spanned with the bobbin, cantilevered.
  • the winding spindle 3 is the traversing device for Traversing the incoming thread 12 assigned.
  • the traversing device parallel to the coil consists of the housing 11, in which a reverse thread shaft 10 is rotatably mounted, and that of the reverse thread shaft Traversing thread guide moved back and forth in a straight line 9, which runs the thread 12 on the spool.
  • a support roller 28 on the housing 11 the traversing device is freely rotatable.
  • the traversing device with the reverse thread shaft is attached to a slide 13.
  • the sled 13 is mounted in a slide guide 14, which is a straight line Movement - radial or secant to the coil allows.
  • a spring 15 acts on the carriage in this way a that the traversing device during the entire winding trip with their support roller 28 against the Coil surface supports, but the growing Diameter of the coil 2 can dodge.
  • the fed thread 12 runs before it from Traversing thread guide 9 laid on the bobbin surface is, between two fixed roles 5 and 6, between which a dancer arm 7 with a dancer roll 29 is pivotally arranged.
  • the dancer role is below the weight of the dancer arm on the thread
  • Sag the shortening the thread loop formed between the thread guides 5 and 6
  • the drive motor 4 attached for driving the winding spindle 3.
  • This drives via a toothed belt pulley 31 and toothed belt 32 one arranged on the upstanding side of the stand plate End of the winding spindle 3 rotatably arranged Toothed belt pulley 33 and herewith the winding spindle 3 centrally.
  • the winding spindle is with the reverse thread shaft 10 connected by gear, namely by toothed belt pulley 16 and toothed belt 19 and toothed belt pulley 18 with a countershaft 30 and from there out through a further toothed belt pulley 26 Timing belt 20 and pulley 17 with the Reverse thread shaft 10.
  • the countershaft 30 is opposite the winding spindle 3 and opposite the reverse thread shaft 10 supported by a pivot lever 23 and 22, respectively and in the free ends of these swivel levers rotatably mounted.
  • the thread runs at a constant speed to. 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 feather - a slack.
  • the size of this slack is determined on the one hand by the delivery speed of the thread and the other through the Winding speed. The size of this slack is adjusted to a constant value. there however, the fluctuations caused by the Traversing movement arise, are allowed.
  • the axis of the dancer arm with a control device 8 connected. Through the control device 8 the drive motor 4 is driven. If the Sag of the thread increases and consequently the dancer arm 7 pivots clockwise, the drive speed of the spindle motor 4 increased. Decreases the sag, the drive speed is 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.
  • the control of the drive motor is in detail 4 designed so that the following functions be carried out:
  • the drive motor 4 is used to thread the thread switched by switch 34 on the dancer arm so that the motor 4 the winding head (coil 2) via a speed controller 37 with a constant predetermined drive speed drives.
  • the speed is chosen so that the peripheral speed of the on the winding spindle 3 stretched empty tube over the Thread speed is.
  • the thread is first used for threading over the thread guides 5 and 6 and around the dancer roll 29 looped.
  • the thread is then attached to the Empty sleeve created and from the rotating empty sleeve captured.
  • the dancer arm 7 lifts out of its lower one Stop position and switches from the landing speed controller 37 via the switch 34 on the dancer arm to the dancer arm control 38 um.
  • the dancer arm with the rotating roller 29 is with one Rotary sensor 40 connected.
  • the rotation sensor By the rotation sensor the position and speed of the dancer arm detected.
  • This magnetoresistive Sensor has a fixed ferromagnetic Layer that is enclosed in a circuit. A magnet acts on this ferromagnetic layer one that is rotatable with the dancer arm. By change the rotational position of the magnetic field changes also 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 also the speed of the dancer arm, and measured according to height and direction. To do this the measurement is repeated at predetermined time intervals and determined the speed from it. 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.
  • the Quantity areas define a membership value, with which a certain position measurement value belongs to the position quantity range previously defined. These membership values are on a scale from 0 to 1.
  • Each quantity range is divided into one Main area and a transition area. By doing The main area has a membership value of 1. In the membership value falls in the transition area the respective adjacent quantity range of 1 drops to 0, although overlaps to the neighboring transition area.
  • the transition area Ib of the quantity range 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 every occurring as a control algorithm Combination of position quantity ranges and Speed-quantity ranges a certain Control value quality range according to Fig. 2C assigned is.
  • the rule algorithm is for example:
  • the result is the fulfillment value.
  • the weighting factor (Measure of trust) for both membership values 1. This results in the membership value (fulfillment value) for the manipulated variable for its selected quantity range with also 0.8.
  • the measured position value is 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 that it determines the centroid of the area, which the selected by the respective Membership values limited quantity ranges cover; d. h .: the overlapping area becomes calculated only once, otherwise the sum of the Quantity ranges formed by the assigned Membership values are limited.
