Abstract (en)
The present invention aims to provide a winding unit having a configuration in which a yarn feeding bobbin is replaced while suppressing rise in manufacturing cost and lowering in quality of a package. As means for achieving such an object, a winder unit (4) of the present invention includes a bobbin holding portion (110), a bobbin supply device (60), a winding section (16), a yarn splicing device (14), a chase portion detection sensor (74), and a determination section (51) . The bobbin holding portion (110) holds a yarn feeding bobbin. The bobbin supply device (60) performs a supplying operation of the yarn feeding bobbin to the bobbin holding portion (110). The winding section (16) performs a winding operation of winding a yarn of the yarn feeding bobbin held by the bobbin holding portion (110) to form a package. The yarn splicing device (14) performs a yarn splicing operation of splicing a yarn end of the package and a yarn end of the yarn feeding bobbin when the yarn is cut. The chase portion detection sensor (74) detects presence/absence of the yarn feeding bobbin at the bobbin holding portion (110). The determination section (51) determines whether or not supply of the yarn feeding bobbin is successful based on a detection result of the chase portion detection sensor (74) after the bobbin supply device (60) performs the supplying operation of the yarn feeding bobbin and until the yarn splicing device (14) starts the yarn splicing operation.
