(57) An object of the present invention is to provide a technique for simplifying wiring
in a yarn winding unit 2. The yarn winding unit 2 includes a winding unit main body
6 and a unit controller 7. The winding unit main body 6 includes a plurality of components
to which at least a yarn supplying section 3, a yarn winding section 5, and a yarn
splicing section 8 correspond. The yarn supplying section 3 supplies a yarn 4. The
yarn winding section 5 winds the yarn 4 supplied from the yarn supplying section 3.
The yarn splicing section 8 is provided between the yarn supplying section 3 and the
yarn winding section 5 to splice the yarn 4. The unit controller 7 controls operation
of the winding unit main body 6. At least one (3, 11, 12) of the plurality of components
includes a motor (15, 36, 41). The winding unit includes a remote I/O board (3r, 11r,
12r). The remote I/O board (3r, 11r, 12r) is configured to be able to communicate
with the unit controller 7. The remote I/O board (3r, 11r, 12r) receives a control
signal from the unit controller 7 to control operation of the component (3, 11, 12)
including the motor (15, 36, 41) based on the received instruction (Fig.1).
