Definitions

  • the invention relates to a method for producing Cross wound in a wild winding by means of a winding device, the means for adjusting the thread tension with which the thread is wound on the package, and / or means to adjust the contact force with which the cheese on a friction roller rests, contains, and a device to perform the procedure.
  • winding density An important property of high quality packages is the winding density. Large fluctuations in the winding density result in problems with further processing, for example when dyeing and especially when unwinding. Modern winding devices, especially of automatic winding machines, possess facilities to keep the winding density in the wild To keep winding wound cheese as constant as possible. It is known the tracking force with which the package rests on a friction roller driving it compensate. It is also known to use the thread tension which thread is wound on the package, constant to keep. Especially when adjusting the thread tension a constant value will give relatively good results achieved with respect to the winding density of a cheese.
  • EP 0 399 243 A discloses an image interference method in which the Avoiding images based on the friction drum designed as a grooved drum a basic speed in such a way braked by means of a drive motor in short intervals and accelerating again that both during acceleration and during of braking between the cheese and the grooved drum slip occurs.
  • the critical image zones have been successfully managed crucial to defuse and create packages that are almost constant Have winding density.
  • the known image interference method cannot be used entirely avoid that the winding density in the area of the image zones deviates somewhat from the winding density in the "normal" coil areas.
  • EP 0 291 712 A which corresponds to the preamble of claims 1 and 8, describes a method in which Setpoint / actual value comparison of the spooled yarn length with the resulting one Cross-bobbin diameter can be seen whether the bobbin in production is a Quality bobbin results or whether the cheese already produced one Represents quality spool.
  • the present invention is based on the aforementioned prior art based on the task of winding density a bobbin and improve a change, in particular, an increase in the winding density largely avoid.
  • This object is achieved in that at least in the area an image zone, the thread tension and / or the contact force can be manipulated in this area the winding density the package to the winding density in the area outside to align an image zone.
  • the invention is based on the knowledge that despite one Thread tension control or compensation of the contact force Areas with increased winding density arise, in particular in areas of so-called image zones. It is known that even when performing image disturbance procedures, for example switching on and off at intervals of the drive motor of the friction roller, in which acceleration phases with slip between the friction roller and Cross-wound bobbin and run-out phases without slippage between the friction roller and package occur, increases in winding density occur. These increases in winding density occur during regulation the thread tension and also with compensation of the contact force on. To avoid these increases in winding density, the thread tension and / or the contact force in the area reduced at least one period in which a Image zone occurs. The thread tension is reduced that a thread tensioner relieves and / or the winding speed is reduced.
  • At least the area of an image zone in a control and / or control device of the winding device is stored is.
  • the area of an image zone can be calculated in advance, and store it accordingly in the control and / or regulating device.
  • the area of an image zone can be reached however, also record during the winding trip, for example taking the difference angle between friction roller and cheese, as is known from DE 42 39 579 A1.
  • the winding density is detected during the manufacture of the package and that by reducing the thread tension and / or the contact force the winding density to a predetermined Setpoint is regulated. This allows a cheese to be wound produce a special in terms of winding density high quality.
  • the object is solved a device in that the winding device a Control and / or regulating device, which for matching the winding density at least in the area of an image zone to the winding density outside the image zone to the middle to adjust the thread tension and / or to the means for Setting the tracking force is connected.
  • the string (10) runs via an adjustable and / or adjustable thread tensioner (16) to a thread guide eyelet (17) and then to Reverse thread (15) of the friction roller (14).
  • the cheese (13) is held by means of bobbins (18), which engage in the coil sleeve (12) and with the coil sleeve (12) and thus rotate with the cheese (13).
  • the coil plate (18) are rotatable in a coil frame (19) stored that the cheese (13) with a predetermined bearing force rests on the friction roller (14).
  • a control and / or regulating device belongs to the winding device (20).
  • the control and / or regulating device (20) gives the speed of a drive motor (21) of the friction roller (14) before. This happens, for example, via a Inverter (22) on the trained as an asynchronous motor Drive motor (21) is connected.
  • the tax- and / or control device (20) also acts only schematically illustrated, adjustable thread tensioner (16), so that the thread tension is adjusted and in particular to a constant Value is adjusted with which the thread (10) the cheese (13) is wound up.
  • the coil frame (19) is shown only schematically Device (23) provided with the tracking force is adjustable with which the cheese (13) on the friction roller (14) rests.
  • the device (23) can work autonomously, i.e. automatically over the coil diameter for one ensure at least approximately constant tracking force.
  • the device (23) of the control and / or Control device (20) is set, for example a constant tracking force is set.
  • a bobbin (18) and the shaft (26) of the friction roller (14) are assigned to angle encoders (24, 25) which are connected to the Control and / or regulating device (20) are connected.
  • At least something about this increase in winding density to mitigate is in the area of this image zone in the winding process intervened.
  • the procedure is usually sufficient on the area of image zones with larger diameters to limit the package (13) because on the one hand the image zones run through faster with smaller coil diameters and on the other hand not increasing the winding density is comparably high.
  • the intervention in the winding process takes place in such a way that an approximation also in the area of the image zone constant yarn application takes place.
  • This manipulation the winding process can be done by reducing the thread tension and / or by reducing the contact force of the cheese (13) on the friction roller (14).
  • the thread tension can be reduced by the thread tensioner (17) something is opened and / or the speed of the drive motor (21) and thus the winding speed is reduced become.
  • the reduction in thread tension and / or the reduction of the circulation in the form of a program stored in the control and / or regulating device (20) are, so this program the course and the height the change in thread tension and / or the change in contact force pretends.
  • the area of an image zone that is predictable is can also in the control and / or regulating device (20) must be filed, so that this depends, for example, on the duration of a winding trip (start of winding with a empty bobbin tube (12) until a full one is completed Cross-wound bobbin (13)) called at a predeterminable time becomes.
  • a winding trip start of winding with a empty bobbin tube (12) until a full one is completed Cross-wound bobbin (13)
  • it is provided that that the area of an image zone during the winding process is detected. This is done, for example, by evaluation the signals of the rotary encoder (24, 25) in the control and / or control device (20) in the manner in which it is made DE 42 39
  • FIG. 3 An evaluation device for determining the current yarn application ( ⁇ ) is shown in FIG. 3. Since the method and device according to the invention can also be used for conical cross-wound bobbins, a conical cross-wound bobbin (13 ') is shown in FIG. 3 together with a friction roller (14). The angular velocities ( ⁇ sp ) and ( ⁇ FW ) are evaluated in a device (27) according to equation (2). Since the diameter (d FW ) of the friction roller (14) is constant, the multiplication by this diameter can also be dispensed with. The angular velocity ( ⁇ sp ) of the cheese (13) is also fed to a revolution counter (28). The two values of the device (27) and the revolution counter (28) are fed to a mathematical filter (29) which is developed from equation (1). This filter then outputs the current thread application ( ⁇ i ).
  • the winding process is interfered with, i.e. the thread tension and / or the tension force is reduced, if at the same time by the control and / or regulating device (20), for example on the basis of the measured angular velocities ( ⁇ sp and ⁇ FW ), has recognized that the area of an image zone is reached.
  • the target value for the yarn application ( ⁇ ) is preferably determined from the values of the yarn application ( ⁇ ) previously measured in an image-free zone.
  • the yarn application is regulated to an approximately constant value of the yarn application ( ⁇ ) by intervening in the thread tension and / or the application force.
