- the stochastic Faults are caused by the deduction of the thread disturbances and the periodic Disturbances that are much larger than the stochastic ones are caused by the laying of the thread conditional disturbances. Since the latter are geometrically conditioned, they can be calculated.
- the invention should now this known method for controlling the thread tension On a textile machine can be improved so that the quality of the compensation of periodic thread tension fluctuations further improved and thereby the tolerance bandwidth the yarn tension in the product produced becomes narrower.
- a first preferred embodiment of the method according to the invention is characterized characterized in that the measurement of the thread tension at fixed positions n times over a Hub of the thread guide takes place, and that the measured values for each position over m laying cycles be determined and averaged.
- the position-dependent determination of the thread tension and the associated synchronization of the The delivery speed of the thread is independent of the stroke and the speed of the thread Yarn guide. This independence allows the compensation of periodic fluctuations the thread tension also at start and stop ramps as well as at low production speeds.
- a second preferred embodiment of the method according to the invention is characterized characterized in that disturbances of the thread tension due to the deviation of the current position-dependent measured value from the value averaged over m cycles.
- a third preferred embodiment of the inventive method is the position-dependent measured value of the thread tension is used as basic controlled variable, which at the reversal points of the thread guide a correction value for a short-term Abbremsung the delivery plant is superimposed.
- a fourth preferred embodiment is characterized in that based on the position-dependent measured value of the thread tension an adaptive adjustment of the delivery speed takes place, in which, depending on the respective position of the yarn guide the delivery speed is increased or reduced.
- the invention further relates to a device for controlling the thread tension on a textile machine, with a motor-driven delivery mechanism for the thread and a thread laying with a yarn guide for winding the yarn on a yarn carrier, wherein the Drive of the delivery mechanism is regulated so that a balance of the thread laying conditional disturbances of the thread tension occurs.
- the inventive device is characterized by a sensor for measuring the thread tension and by an evaluation stage for the sensor signals, in which an assignment of the measured values of the sensor to respective position of the thread guide, and by means for an ongoing synchronization between the position of the thread guide and the control of the thread delivery.
- a first preferred embodiment of the device according to the invention is characterized characterized in that an averaging of the measured values of the thread tension for the individual Positions over a number of laying cycles takes place.
- a second preferred embodiment of the device according to the invention is characterized in that that the determination of the named controlled variable takes into account the current thread speed occurs.
- a third preferred embodiment of the device according to the invention is characterized in that that a first control stage for the drive of the yarn carrier and the thread laying and provided with this second control stage for the drive of the delivery mechanism of which one contains the mentioned evaluation stage, and that between the both control stages an ongoing transmission and synchronization of the position of the thread guide he follows.
- a further preferred embodiment of the device according to the invention is characterized characterized in that the thread guide performs a reciprocating traversing movement, and that the drive of the delivery mechanism is regulated so that at the reversal positions of the Yarn guide a serving to compensate for the downtime of the yarn guide reduction the yarn delivery speed takes place.
- the invention further relates to an application of said method to winding machines, Aircovering machines or texturing machines.
- the winding station shown in Fig. 1 consists of a Aufsteckung 1 for receiving a feed bobbin 2 with a thread F, a thread insulation 3, one of a motor 4 driven Delivery mechanism 5, a sensor 6 for measuring the tension of the thread F and a Winding unit 7.
- the latter consists of a by a motor (not shown) drivable Spindle 8 for receiving and holding a bobbin tube 9, on which a coil 10th is wound, and from a thread laying 11.
- the drive of the coil 10th take place via a motor-driven friction roller on which the coil 10 rests (see EP-A-1 125 878).
- the thread laying 11 contains a thread guide as the most essential element 12, which performs an oscillating traversing movement along the axis of the spool 10.
- a oscillating traversing motion yarn guide 12 can also be a so-called Wing-thread laying of the type described in EP-A-0 997 422 may be provided.
- a such wing thread laying has two counter-rotatable, superimposed Thread guide wing and a bow disc on. The thread guide wings emerge from the contour of the Arch disc out and dive back into this, where at the immersion points of the Thread guide wings in each case the transfer of the thread takes place.
- the yarn guide 12 is movable to and fro in a rail or groove-like guide Glide element 13 attached to which a traversing element 14 attacks.
- This is as flexible and stiff in traversing direction organ for transmitting tensile forces formed and for example by a string, a wire, a metal cable, a flat, toothed or V-belt, a metal band, a chain or the like. Formed.
- the traversing element 14 passes over two Rollers 15 and 16, one of which, according to the role of the roller 16, as a drive wheel for the Drive of the traversing element 14 is used.
- the drive wheel 16 is by a servo motor (not shown), preferably a stepper motor, driven.
- the drive wheel 16 is mounted directly on the motor shaft.
- the engine is a sensor (not shown) for detecting the rotational position of the drive wheel 16 and thus associated with the traversing position of the thread guide 12. Regarding this sensor is on the EP-A-0 829 444 and corresponding US-A-5,918,829.
- the sensor is a consisting of a transmitting and a receiving diode photoelectric sensor, the Movement of the drive wheel 16 or scanned with this rigidly connected disc.
- the Driving wheel 16 or the disc is for this purpose with suitable optically scannable markings, for example, with holes or slots arranged along a circle.
- the drive motors of the spindle 8 and the drive wheel 16, the sensor for the traversing position the thread guide 12 and any other sensors, for example, for the speed of Coil 10, are connected to a spindle control 17, which uses the aforementioned motors programmed winding parameters and winding laws as well as those of the sensors controls supplied data.
- the spindle control 17 is also provided with a delivery control 18 connected, which in turn with the yarn tension sensor 6 and the drive motor. 4 of the delivery plant 5 is connected.
- the thread tension sensor 6 measures the variations in the thread tension at fixed Positions n times over a hub. These measured values are determined over m laying cycles and averaged. The values obtained thus show an image of the thread shortening or thread extension before the thread laying 11 and form the pilot value for the controlled variable of Thread delivery.
- Important for the position-dependent determination of the thread tension is the Information on which position the yarn guide 12 is at a certain time. This information is continuously high priority between the spindle control 17 and the Delivery control 18 exchanged and there is a synchronization of the time base.
- Periodic thread fluctuations are disturbances caused by the thread laying 11 are.
- a look at the geometry of the thread laying shows that because of the linear Movement of the thread guide 12, the length of the thread F between this and the thread tension sensor 6 at the reversal points of the traversing movement is greater than in the middle.
- the geometry of the thread laying 11, which is well known, is used to thread delivery 5 to decelerate briefly at the reversal points of the yarn guide 12. At these reversal points There is a significant, but dependent on the Bewicklungsin throttling the Motor 4 to compensate for the downtime of the yarn guide 12 at the reversal points.
- the diagram of Fig. 2 shows the control loop for the described control of the thread tension: At the top left you can see the parameters of the spindle control 17 specifiable 19, this is the laying geometry and the winding geometry, including that of the delivery control 18 predefinable setpoint 20 of the thread tension. The latter is via an adder 21 and a transfer function 22 associated with the parameters 19.
- the adder 21 is also the actual value of the thread tension measured and processed by the thread tension sensor 6 fed.
- transfer function 22 the mathematical relationship between input and output signal in consideration of a time delay. With In other words, responding to a change in the input of the transfer function 22 their output in a characteristic way with a new value.
- the link of the Output of the transfer function 22 with the parameters 19 reaches the controlled system 23, this is the element to be influenced or the part of the control loop to be controlled.
- these are the thread F and the Properties of the elements which the thread F touches on its way.
- Such properties are, for example, the surface of the drive roller (delivery mechanism 5) and the surfaces all deflection points.
- the material parameters 24 of the thread F are essential for the scheme. They are listed as a separate box because it depends on the Material other rule settings can be used.
- the output signal of Level 24 is the actual value of the thread tension / thread tension.
- the thread tension will be n times fixed positions (angle synchronous) and measured by the controller in a step 25 over m Averaged samples.
- the thread tension thus sets the position-dependent actual value to regulating variable 26 is the control algorithm 26, for example, a PD controller, PID controller or 3-point controller. Disturbances of the thread tension are recognized as such, because their current Value deviates from the value averaged over m periods.
