Abstract
A method and device of cleaning the rotor (6) of a rotor spinning machine are provided in which, after the opening of a spinning unit, there are sucked off from the rotor (6) fibres and impurities being released from the inner surface of the rotor by pressure air applied to said inner surface. The cleaning pressure air is led into the rotor (6) in at least two air streams producing in the rotor 6 a symmetrical streaming in one and the same direction and the supplied air, together with the released impurities, is sucked off through the center of the inlet aperture (63) of the rotor (6).
Claims17
A textile machine, said machine comprising:
- at least one rotor spinning machine including a rotor defining an inlet aperture to a spinning rotor interior;
- and
- a rotor cleaning assembly, said rotor cleaning assembly including
- a positive air pressure source;
- a negative air pressure source;
- a cleaning head configured to be positioned in an operating position proximate said spinning rotor inlet aperture;
- a suction tube configured in said cleaning head in communication with said negative pressure source, said suction tube having an inlet aperture proximate said spinning rotor inlet aperture when said cleaning heads is in the operating position such that air is drawn from said spinning rotor interior through said suction tube inlet aperture;
- and
- a plurality of air inlets disposed about the perimeter of said suction tube inlet aperture, each said air inlet in communication with said positive air pressure source and configured to introduce an air stream into said spinning rotor interior in a direction with respect to said spinning rotor such that the air streams of all of said plurality of air inlets create a resulting air stream circulating within said spinning rotor interior to loosen impurities therein, and
- wherein said negative pressure source and said suction tube are configured to draw air from said spinning rotor interior to withdraw impurities loosened the resulting circulating air stream.
