Abstract

Beim Umspulen von Ablaufspulen auf Kreuzspulen an Spulvorrichtungen eines Spulautomaten können dann, wenn nur noch wenige Garnlagen auf der Hülse der Ablaufspule vorhanden sind, Schwierigkeiten beim Abziehen des Fadens auftreten, die sich in Fadenverhakungen und in deren Folge als Spannungsbrüche äußern. When rewinding from reels to cross-wound bobbins Winding devices of an automatic winder can then, if only there are few layers of yarn on the core of the payout spool, Difficulty pulling the thread occur, which can result in Thread hooks and as a result express them as tension breaks.

Zur Überwindung dieser Schwierigkeiten wird ein Verfahren zur Erkennung von Ablaufspulen vorgestellt, deren Ablaufeigenschaften einer vorgebbaren Güte nicht entsprechen. Dazu wird die Spulgeschwindigkeit gemessen und ein Fadenbruch in Relation zur Spulgeschwindigkeit zur Erkennung der Güte der Ablaufspule herangezogen und bei Unterschreiten der vorgegebenen Güte die entsprechende Ablaufspule ausgeworfen und mit einer neuen Ablaufspule der Spulvorgang fortgeführt. To overcome these difficulties, a method for Detection of payout coils presented, their payoff properties do not correspond to a specifiable quality. For this, the Spooling speed measured and a thread break in relation to Spooling speed to detect the quality of the payout spool used and if the specified quality falls below the appropriate spool ejected and with a new one The winding process continued.

Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens sieht eine Signalverarbeitungseinrichtung (11) vor, in der das Spulgeschwindigkeitssignal bis zu einer vorgebbaren Spulgeschwindigkeit und das Fadenbruchsignal eingebbar sind. Die Signalverarbeitungseinrichtung (11) erzeugt dann ein Signal und gibt es ab, wenn das Signal der Spulgeschwindigkeit unterhalb des vorgebbaren Spulensignals und das Fadenbruchsignal gleichzeitig anstehen. The inventive device for performing the method provides a signal processing device (11) in which the Winding speed signal up to a predeterminable Winding speed and the thread break signal can be entered. The Signal processing device (11) then generates a signal and emits when the signal of the winding speed below the Predeterminable bobbin signal and the thread break signal at the same time queue.
