"Winding Unit And Yarn Winding Machine Equipped With Same"
Abstract: 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 of the present invention includes a bobbin holding portion, a bobbin supply device, a winding section, a yarn splicing device, a chase portion detection sensor, and a determination section. The bobbin holding portion holds a yarn feeding bobbin. The bobbin supply device performs a supplying operation of the yarn feeding bobbin to the bobbin holding portion. The winding section performs a winding operation of winding a yarn of the yarn feeding bobbin held by the bobbin holding portion to form a package. The yarn splicing device 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 detects presence/absence of the yarn feeding bobbin at the bobbin holding portion. The determination section determines whether or not supply of the yarn feeding bobbin is successful based on a detection result of the chase portion detection sensor after the bobbin supply device performs the supplying operation of the yarn feeding bobbin and until the yarn splicing device starts the yarn splicing operation.
