Abstract

Es wird ein Verfahren und eine Vorrichtung zum Aufwickeln eines kontinuierlich zulaufenden Fadens auf eine Spule einer Spulmaschine aufgezeigt, bei dem ein Drehteller, auf dem zwei antreibbare Spulspindeln drehbar gelagert sind, gegenüber einer Kontaktwalze kontinuierlich mit sich in der Regel ändernden Winkelgeschwindigkeiten unabhängig von einer Bewegung der Kontaktwalze gedreht wird. Der Faden wird mit einer Verlegeeinrichtung über die Kontaktwalze auf die Spule aufgewickelt. Der Abstand zwischen der Achse der Kontaktwalze und der Achse der in Betrieb befindlichen Spulspindel wird im Sinne einer Vergrößerung entsprechend dem wachsenden Durchmesser der Spule ohne Unterbrechung des Antriebes des Drehtellers verändert. Der jeweis aktuelle Durchmesser DS der Spule wird aus der ermittelten Drehzahl nS der Spulspindel und aus der ermittelten Drehzahl nK der Kontaktwalze oder der ermittelten Zuliefergeschwindigkeit des Fadens berechnet. An festgelegten Stützpunkten über die Spulreise wird der jeweils aktuelle Istdrehwinkel αist des Motors des Drehtellers ermittelt und unter Anwendung einer Formel betreffend die geometrischen Beziehungen der Spulmaschine oder durch Vergleich mit einer hinterlegten Wertetabelle der jeweils aktuelle Solldrehwinkel αsoll des Motors des Drehtellers, der zu dem jeweils aktuellen Durchmesser DS der Spule gehört, ermittelt. An den festgelegten Stützpunkten wird eine jeweils aktuelle Winkeldifferenz Δα zwischen dem jeweils aktuellen Solldrehwinkel αsoll und dem jeweils aktuellen Istdrehwinkel αist des Motors des Drehtellers gebildet. Der Motor des Drehtellers wird an den festgelegten Stützpunkten mit den den jeweils aktuellen Winkeldifferenzen Δα entsprechenden Signalen als Stellgrößen angesteuert.

Figure 00000001
A method and a device for winding up a continuously running thread on a bobbin of a winding machine are shown, in which a turntable, on which two drivable winding spindles are rotatably mounted, is continuously opposite the contact roller with a generally changing angular speed, regardless of a movement of the Contact roller is rotated. The thread is wound onto the bobbin with a laying device via the contact roller. The distance between the axis of the contact roller and the axis of the winding spindle in operation is changed in the sense of an increase in accordance with the growing diameter of the coil without interrupting the drive of the turntable. The current diameter D S of the bobbin is calculated from the determined speed n S of the winding spindle and from the determined speed n K of the contact roller or the determined feed speed of the thread. At fixed support points during the winding cycle of each current Istdrehwinkel is α of the motor of the turntable is determined and using a formula relating to α the geometrical relationships of the winding machine or by comparison with a stored table of values of the respective current target rotational angle of the motor of the turntable, which at the current diameter D S belongs to the coil, determined. A respective current angular difference Δα is intended α between the current target rotational angles on the fixed bases and the motor of the turntable is α the current Istdrehwinkel formed. The motor of the turntable is actuated at the defined support points with the signals corresponding to the respective current angle differences Δα as manipulated variables.
