Definitions

  • Dishwasher for a thread running at a constant speed
  • the invention relates to a dishwasher, according to the preamble of claim 1.
  • This winding machine is known from DE-OS 39 33048 (Bag. 1659).
  • the sag of the dancer arm is regulated by adjusting the spindle speed with the aid of a PI controller, which is switched on after the thread is applied and the traversing device is switched on to the dancer arm. Due to the strong integral part of the controller, the spindle drive motor responds only with a delay
  • the object of the invention is to design the dishwasher with its control so that the control is able to correct all fluctuations in the position of the dancer arm without switching, including those fluctuations which are caused by the back and forth movements of the traversing device.
  • the controller is programmable and adjustable over a wide range, so that all operating states can be detected and converted into discrete manipulated values, and that the control system can be used Operating conditions can be adjusted sensitively, with the extreme conditions - such as. B. putting on and moving off - no switching required.
  • a precision cheese head is shown in perspective. 2 shows diagrams to illustrate the measuring and control method. Precision bobbins of this type are arranged side by side in a number of horizontal and vertical rows in a precision cheese winder.
  • the precision cheese head is arranged in a vertical stand plate 1.
  • the winding spindle 3, on which the bobbin with the winding tube is clamped, is cantilevered.
  • the traverse device 3 is assigned the traversing device for traversing the incoming thread 12.
  • the traversing device is parallel to the coil from the housing 11, in which a reversing thread shaft 10 is rotatably mounted, and the traversing thread guide 9, which is moved back and forth by the reversing thread shaft in a straight guide and which moves the thread 12 on the bobbin.
  • a support roller 28 is freely rotatably mounted on the housing 11 of the traversing device.
  • the traversing device with the reverse thread shaft is attached to a slide 13.
  • the slide 13 is mounted in a slide guide 14, which allows a linear movement - radial or secant to the coil.
  • a spring 15 acts on the carriage in such a way that the traversing device is supported with its support roller 28 against the surface of the spool during the entire winding travel, but can avoid the increasing diameter of the spool 2.
  • the fed thread 12 runs, before it is laid on the bobbin surface by the traversing thread guide 9, over two fixed rollers 5 and 6, between which a dancer arm 7 with a dancer roller 29 is pivotably arranged.
  • the dancer roll lies on the thread under the weight of the dancer arm. Due to the growth of the bobbin 2 and the shortening of the thread loop (sag) formed between the thread guides 5 and 6, the pivoting angle of the dancer arm is changed and, depending on this, the speed of the drive motor 4 for the bobbin spindle is adjusted electronically by a mechanical-electrical dancer arm control.
  • the drive motor 4 for driving the winding spindle 3 is fastened on the other side of the stand plate (at the front as seen by the viewer). Via a toothed belt pulley 31 and toothed belt 32, this drives a toothed belt pulley 33, which is arranged on the end of the winding spindle 3 and projects cantilevered, and thereby drives the winding spindle 3 centrally.
  • the winding spindle is connected to the reversing thread shaft 10 by gear Toothed belt pulley 16 and toothed belt 19 and toothed belt pulley 18 with a countershaft 30 and from there through a further toothed belt pulley 26 via toothed belts 20 and toothed belt pulley 17 with the reversing thread shaft 10.
  • the countershaft 30 is opposite the winding spindle 3 and opposite the reversing thread shaft 10 by a pivot lever 23 or 22 supported and rotatably supported in the free ends of these pivot levers.
  • the thread runs at a constant speed.
  • a sag is formed between the thread guides 5 and 6 due to the constant weight of the dancer arm 7 with the dancer roller 29 - possibly reinforced by a spring.
  • the size of this slack is determined on the one hand by the feed speed of the thread and on the other hand by the winding speed.
  • the size of this slack is adjusted to a constant value.
  • the fluctuations caused by the traversing movement must be allowed.
  • the axis of the dancer arm is connected to a control device 8.
  • the drive motor 4 is controlled by the control device 8.
  • the dancer arm 7 and the control device 8 are therefore 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 the following functions are carried out:
  • the drive motor 4 is switched by means of switch 34 on the dancer arm so that the motor 4 the winding head (bobbin 2) drives via a contact speed controller 37 at a constant predetermined drive speed.
  • the speed is selected so that the peripheral speed of the empty tube spanned on the winding spindle 3 is above the thread speed.
  • the thread is first passed over the thread guides 5 and 6 and looped around the dancer roll 29. The thread is then placed against the empty tube and caught by the rotating empty tube.
  • the dancer arm 7 lifts from its lower stop position and switches from the applied speed controller 37 to the dancer arm control 38 via the switch 34 on the dancer arm.
  • the dancer arm with the rotating roller 29 is connected to a rotation sensor 40.
  • the position and speed of the dancer arm is detected by the rotary sensor.
  • This can be a magnetoresistive sensor, for example.
  • This magneto-resistive sensor has a fixed ferro-magnetic layer which is enclosed in a circuit.
  • a magnet which can be rotated with the dancer arm, acts on this ferromagnetic layer.
  • the electrical resistance of the ferromagnetic layer also changes, so that the voltage drop across the ferromagnetic layer is a measure of the rotational position of the dancer arm.
  • the speed of the dancer arm is also measured, in terms of height and direction. For this purpose, the measurement is carried out at predetermined time intervals repeated and the speed determined from this. The continuously determined position measurement values and the speed measurement values are now given to the controller.
  • the controller has a memory with different memory areas.
  • Position quantity areas are stored in the position storage area. These position quantity ranges are shown in Fig. 2A.
  • the quantity ranges define a membership value with which a specific position measurement value belongs to the previously defined position quantity range. These membership values are on a scale from 0 to 1.
  • Each quantity area is divided into a main area and a transition area. In the main area, the membership value has the value 1. In the transition area, the membership value for the respectively adjacent quantity area drops from 1 to 0, although there are overlaps with the adjacent transition area.
  • FIG. 2A shows position quantity ranges I to III.
  • the horizontal line of the main area Ia denotes the position quantity area: "far below”.
  • the transition range Ib of the quantity range I covers all measured values, which can only be assigned to the quantity range "far below” with restrictions.
  • the quantity range I covers all measured values which are directed downwards and are "very high".
  • the quantity range II covers all measured values which are directed downwards and are "medium-high",
  • the quantity range III covers all measured values which are to be classified essentially as "equal to zero" or "low",
  • the quantity range IV covers all measured values which are directed upwards and are to be classified as "medium-high",
  • the quantity range V covers all measured values which are directed upwards and are "very high".
  • FIG. 2C shows that the scale of the control values occurring is divided into five quantity ranges.
  • the relevant manipulated values are assigned to the following quantity ranges: I: Reduce speed significantly
  • the memory also has a memory area in which, as a control algorithm, every occurring combination of position quantity ranges and speed quantity ranges is assigned to a specific manipulated variable quality range according to FIG. 2C.
  • the rule algorithm is, for example:
  • the membership value (fulfillment value) of the manipulated value for the selected quantity range II is obtained, for example, by multiplying the membership values for position and speed for their relevant quantity range. Prior to this multiplication or other superimposition, the membership values can also be weighted, which reflects the degree of trust in the membership.
  • 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, also with 0.8.
  • FIG. 2C shows that of the manipulated variable quantity range II "negative medium", the area below the 0.8 horizontal indicates the range from which the manipulated variable is selected.
  • the computer also contains a control algorithm for this.
  • This control algorithm can say, for example, that the manipulated value is the abscissa of the centroid of the area, which is cut off from the quantity range under consideration by the membership value.
  • 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 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 for the respective quantity range results from the membership values of the measured value for the assigned position or speed quantity ranges by superimposition as previously described.
  • the computer is in turn programmed so that it determines the centroid of the area which covers the selected quantity ranges limited by the respective membership values; ie: the overlapping area is only calculated once, the rest is the sum of the Quantity ranges formed, which are limited by the assigned membership values.

Abstract

Le fil est acheminé à vitesse constante jusqu'à la bobineuse. La régulation de la vitesse de bobinage est assurée par le fait que le fil est guidé par l'intermédiaire d'un bras danseur. Outre la valeur mesurée qui représente la position du bras danseur, la vitesse à laquelle ledit bras danseur modifie sa position est déterminée. Les deux valeurs mesurées sont superposées et servent à déterminer une valeur d'ajustement pour le moteur de la broche.
