- the effective distance is preferably entered as a distance from an edge of a coil to be produced.
- a second preferred embodiment of the method according to the invention is characterized characterized in that the thread tension profile by entering one of several value pairs specified with the position of the thread guide and the thread tension existing curve which refers to the stroke length to be wound.
- the thread tension profile depending on the coil diameter and / or other Parameters can be specified.
- Such further parameters are, for example, by the stroke of Thread guide, the bevel of the coil to be produced or the compensation of Bulges formed.
- the invention further relates to a device for controlling the thread tension on a winding 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, 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, by means for an ongoing synchronization between the position of the thread guide and the control of the thread delivery and by means for specifying a thread tension profile.
- a first preferred embodiment of the device according to the invention is characterized in that a control of the thread tension profile corresponding to the Delivery plant takes place.
- a second preferred embodiment of the device according to the invention is characterized in that that the specification of the thread tension profile by entering an effective distance and a percentage reduction of the nominal yarn tension occurs.
- a third preferred embodiment of the device according to the invention is characterized characterized in that the specification of the thread tension profile by entering a several value pairs with the position of the thread guide and the associated thread tension Existing and related to the stroke length to be wound curve takes place.
- the invention further relates to an application of said method to influence the quality of the coil edges.
- the application according to the invention is characterized in that the position-dependent Control of the thread tension for softening or hardening of the edges of the manufactured Coils, for generating beveled coil edges, to compensate for bulges or used in asymmetric coil construction of cylindrical or conical coils becomes.
- 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.
- This difference in length corresponds to a difference in the thread tension, which at the Reversal points is greater than in the middle.
- the thread tension reaches at one Reversal point their maximum value, decreases towards the middle, reaches there their lowest value and then rises again until the reversal point.
- 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.
- Thread tension profile given to the quality of the coil 10 in total and in particular to improve on the coil edges.
- quality improvement measures include Targeted edge softening or edge hardening, as well as influencing the thread tension at chamfer of the coil edges, with compensation of bulges and at asymmetric coil construction.
- the thread tension profile is the diameter of the coil 10 and / or the stroke of the thread guide 12 dependent and it is by the thread laying 11 by a corresponding Control of the thread feed realized by the thread delivery 5.
- the thread tension becomes by entering an effective distance, that is, for example, the distance from an edge of the coil 10, and a percentage change in the target thread tension or by entering a given curve defined by several pairs of values, each of which depends on the complies with the stroke length. In most cases (edge softening) it will be at the Change the thread tension by a thread tension reduction act. In the mentioned Value pairs are the position of the thread guide 12 and the corresponding Thread tension. There may be different winding lengths and take-up speeds be taken into account, and the thread tension profile depends on other parameters, such as bevel or compensation adaptable and it is also on conical coils applicable, the thread tension change is reproducible and operate in all operating conditions.
- 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 and the predefinable thread tension profile. The latter are via an adder 21 and a transfer function 22 with the Parameters 19 linked. The adder 21 is also that of the yarn tension sensor 6 measured and processed actual value of the thread tension supplied. With transfer function 22 is the mathematical relationship between input and output signal under consideration termed a time delay. In other words, in a change at the input of the transfer function 22 whose output reacts in a characteristic manner with a new value.
- the linking of the output of the transfer function 22 with the Parameters 19 reaches the controlled system 23, which is the member to be influenced or to regulating part of the control loop.
- the controlled system 23 is the member to be influenced or to regulating part of the control loop.
- these are the thread F and the properties of the elements which the thread F on touched his way.
- Such properties are, for example, the surface of the drive roller (Delivery mechanism 5) and the surfaces of 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.
