Abstract
An attending device of a textile machine, in particular of a rotor spinning machine, is provided having pneumatic pressure means intended to attend a working place and being disengageably connected to an overpressure source, and having underpressure pneumatic means disengageably connected to an underpressure source. The underpressure source and the overpressure source are made as a pneumatic generator situated on the attending device, and a closed filter of impurities mounted on the attending device is inserted before the air inlet into the pneumatic generator.
Claims27
A textile machine attending assembly to be disposed proximate the textile machine to perform attending operations thereto, said assembly comprising:
- an attending unit configured to travel along the textile machine;
- a pneumatic pressure generator disposed on said attending unit, said pneumatic pressure generator having an outlet and an inlet and generating a negative pneumatic pressure at said inlet and a positive pneumatic pressure at said outlet;
- at least one positive pneumatic pressure cleaning mechanism and at least one yarn handling mechanism in communication with said pneumatic pressure generator outlet, said positive pneumatic pressure mechanisms performing one of a predetermined yarn handling operation and cleaning operation at the textile machine which requires a source of pressurized air;
- at least one negative pneumatic pressure cleaning mechanism and at least one yarn handling mechanism in communication with said pneumatic pressure generator inlet, said negative pneumatic pressure mechanisms performing one of a predetermined yarn handling operation and cleaning operation at the textile machine which requires a source of negative pressure air;
- a control device in communication with said positive pneumatic pressure mechanisms and said negative pneumatic pressure mechanisms to selectively operate said mechanisms for said yarn handling and cleaning operations;
- and
- an air filter mechanism disposed upstream from said pneumatic pressure generator inlet to filter air entering said inlet from said negative pneumatic pressure mechanisms, wherein-the filtered air is directed to said positive pneumatic pressure mechanisms.
