Abstract (en)

The present invention provides a bobbin replacing device, a rotor spinning machine using the same, and a bobbin replacing method thereof. The bobbin replacing device includes a bobbin holder for storing an empty bobbin and a driving mechanism capable of driving the bobbin holder to move to a predetermined position. In the spinning machining using the bobbin replacing device, when the bobbin does not need to be changed, the bobbin holder locates at a first position; when the bobbin needs to be changed, the bobbin holder is driven by the driving mechanism to move to a predetermined second position, and the bobbin on the bobbin holder arrives at a predetermined position; the driving mechanism drives the bobbin holder to return to an original position, thereby achieving an automatic bobbin replacement and reducing the worker's labor intensity.
