When the yarn Y is cut by a certain spinning unit 2 or the yarn Y is cut for some reason, the yarn joining cart 3 performs a yarn joining operation with the spinning unit 2. The doffing cart doffs the package P and supplies a new bobbin B to the spinning unit 2 when the package P is full in a spinning unit 2.

  The first end frame 4 accommodates a collection device for collecting fiber waste and yarn waste generated in the spinning unit 2. The second end frame 5 is configured to adjust the air pressure of the compressed air (air) supplied to the spinning machine 1 to supply air to each part of the spinning machine 1 and to supply power to each part of the spinning unit 2. A drive motor or the like is stored. The second end frame 5 is provided with a machine control device 41, a display screen 42, and input keys 43.

An apron belt 18 a is provided for the bottom roller of the middle roller pair 16. An apron belt 18 b is provided for the top roller of the middle roller pair 16.

  The air spinning device 7 generates a yarn Y by twisting the fiber bundle F drafted by the draft device 6 by a swirling air flow. More specifically (however, illustration is omitted), the pneumatic spinning device 7 includes a spinning chamber, a fiber guide portion, a swirling air flow generation nozzle, and a hollow guide shaft body. The fiber guide unit guides the fiber bundle F supplied from the upstream draft device 6 into the spinning chamber. The swirling air flow generating nozzle is disposed around the path along which the fiber bundle F travels, and generates a swirling air flow in the spinning chamber. By this swirling air flow, the fiber ends of the plurality of fibers constituting the fiber bundle F are reversed and swirled. The hollow guide shaft body guides the yarn Y from the spinning chamber to the outside of the pneumatic spinning device 7.

  The yarn monitoring device 50 monitors information on the traveling yarn Y between the pneumatic spinning device 7 and the yarn storage device 11, and detects the presence or absence of a yarn defect based on the monitored information. When the yarn monitoring device 50 detects a yarn defect, the yarn monitoring device 50 transmits a yarn defect detection signal to the unit controller 10.

When the unit controller 10 determines that there is an abnormality based on the detection result of the yarn monitoring device 50 and / or the tension sensor 9, the yarn Y is cut in the spinning unit 2. Specifically, the supply of air to the pneumatic spinning device 7 is stopped and the generation of the yarn Y is interrupted, whereby the yarn Y is cut. Alternatively, the yarn Y may be cut by a cutter provided separately.
