Abstract

Die Erfindung betrifft eine Arbeitsstelle (2) und ein Verfahren zum Betreiben der Arbeitsstelle einer Offenend-Rotorspinnmaschine (1) mit einem Spinnrotor (10) zum Spinnen eines Fadens (7), mit einem elektrischen Motor (24) zum Antreiben des Spinnrotors (10) und einem Netzteil (22) zur Bereitstellung einer Versorgungsspannung, wobei der elektrische Motor (24) bei Ausfall der Versorgungsspannung als Generator betreibbar ist und wobei die Arbeitsstelle (2) zumindest einen elektrischen Antrieb (11a) einer Wickelwalze (11) zum Antreiben einer Garnspule (8) und eine elektrische Steuereinrichtung (16a) einer Fadenabzugseinrichtung (16) aufweist. Erfindungsgemäß ist eine Schaltungsanordnung (60) dazu ausgebildet, bei Ausfall der Versorgungsspannung des Netzteils (22) die elektrische Energie des als Generator betriebenen elektrischen Motors (24) zum Antreiben des Spinnrotors (10) zumindest dem elektrischen Antrieb (11a) der Wickelwalze (11) und der elektrischen Steuereinrichtung (16a) der Fadenabzugseinrichtung (16) zuzuführen und andere nicht benötigte elektrische Verbraucher (21) der Arbeitsstelle (2) von der elektrischen Energiezufuhr zu entkoppeln.

The invention relates to a workstation (2) and a method for operating the workstation of an open-end rotor spinning machine (1) with a spinning rotor (10) for spinning a thread (7) with an electric motor (24) for driving the spinning rotor (10). and a power supply (22) for providing a supply voltage, wherein the electric motor (24) is operable as a generator in the event of a power failure and wherein the workstation (2) comprises at least one electric drive (11a) of a winding roller (11) for driving a yarn package (11). 8) and an electrical control device (16a) of a thread withdrawal device (16). According to the invention, a circuit arrangement (60) is designed, in the event of failure of the supply voltage of the power supply unit (22), the electrical energy of the electric motor (24) operated as a generator for driving the spinning rotor (10) at least the electric drive (11a) of the winding roller (11). and to supply the electrical control device (16a) to the thread withdrawal device (16) and to decouple other unneeded electrical consumers (21) from the electrical power supply to the workstation (2).
