Method for operating a spinning station of a spinning machine, and spinning machine

Abstract

A method for operating a spinning station of a spinning machine includes, during a downtime of the spinning station, performing one or both of: driving and stopping the opening roller at least one time by means of an individual drive configured with the opening roller, or driving the opening roller at a minimum rotation speed by means of the individual drive.

         11 . A method for operating a spinning station of a spinning machine, wherein the spinning machine includes:
 an opening unit that opens a fiber material into individual fibers that are spun into a yarn by means a spinning device;   the opening unit including an opening roller rotatably mounted in an opening housing and drivable by an individual drive,   the spinning device connected to a negative pressure channel of the spinning machine and acted upon by negative pressure,   the opening housing connected to the spinning device via a feed duct;   the method comprising:   during a downtime of the spinning station, performing one or both of: driving and stopping the opening roller at least one time by means of the individual drive, or driving the opening roller at a minimum rotation speed by means of the individual drive.   
     
     
         12 . The method according to  claim 11 , wherein the opening roller is driven counter to an operational direction of rotation during the downtime of the spinning station. 
     
     
         13 . The method according to  claim 11 , wherein the opening roller ( 15 ) is repeatedly driven and stopped at predetermined time intervals during the downtime of the spinning station. 
     
     
         14 . The method according to  claim 13 , wherein the time intervals are set in a control unit of the spinning station or a control unit of the spinning machine. 
     
     
         15 . The method according to  claim 13 , wherein the time intervals are set in an application-specific manner depending on the fiber material being spun at the spinning station. 
     
     
         16 . The method according to  claim 11 , further comprising additionally cleaning the opening roller with a bast air stream from a spinning station-specific blowing nozzle. 
     
     
         17 . A spinning machine, comprising:
 a plurality of adjacently arranged spinning stations, wherein each of the spinning stations comprises:
 an opening unit that opens a fiber material into individual fibers that are spun into a yarn by a spinning device; 
 the opening unit including an opening roller rotatably mounted in an opening housing and drivable by an individual drive; 
 the spinning device connected to a negative pressure channel of the spinning machine and acted upon by negative pressure; 
 the opening housing connected to the spinning device via a feed duct; 
   the spinning machine or each spinning station further comprising a control unit configured to control the spinning stations to perform one or both of the following during a downtime of the spinning station: driving and stopping the opening roller at least one time by means of the individual drive, or driving the opening roller at a minimum rotation speed by means of the individual drive.   
     
     
         18 . The spinning machine according to  claim 17 , wherein the opening roller is drivable at predetermined time intervals set by the control unit. 
     
     
         19 . The spinning machine according to  claim 18 , characterized in that the time intervals are stored in the control unit and are application-specific depending on the fiber material being spun at the spinning station. 
     
     
         20 . The spinning machine according to  claim 18 , wherein each spinning station further comprises a station-specific blowing nozzle for additional cleaning the opening roller.
