Rotor spinning machine and method for renewing the spinning process on the workstation of a rotor spinning machine

摘要

The invention relates to a rotor spinning machine having a plurality of spinning units (1) for producing a yarn (2), wherein the spinning unit (1) has a feed device (11) for a sliver (21) which has a single drive (112) and which is provided with a control unit (6 ), wherein the spinning unit (1) comprises a spinning rotor (140) formed by a mutually open rotor having a single drive integrated in a magnetic bearing (146) common to the drive and the spinning rotor (140) in a hinged lid (14) of the spinning unit (1) is arranged, wherein the spinning rotor (140) is mounted in a vacuum chamber (16) which is coupled by a vacuum channel (161) with the vacuum source. A hinged lid (14) of the spinning unit (1) is provided with means (151) for its at least partially automatic opening for automatic suction of the end of a yarn (2) into the vacuum channel (161) outside the edge of the inlet opening (142) of the spinning rotor (140) and for automatically closing the lid (14) coupled, wherein the lid (14) in the fully open position for possible manual cleaning of the spinning rotor (140) or for its replacement is hinged.
