Abstract

The invention provides a winding unit (4) capable of performing a satisfactory winding operation by accurately aligning a position of an unwinding side end of a yarn feeding bobbin (21) with respect to a target position regardless of a diameter and / or a shape of the yarn feeding bobbin (21). A winder unit (winding unit) (4) includes a bobbin holding portion (110), a chase portion detection sensor (the yarn feeding bobbin detection unit) (74), a drive portion (200), and a stepping motor controller (102). The bobbin holding portion (110) holds the yarn feeding bobbin (21). The chase portion detection sensor (74) detects an unwinding side end of the yarn feeding bobbin (21) held by the bobbin holding portion (110). The drive portion (200) drives the bobbin holding portion (110) to adjust the position of the unwinding side end of the yarn feeding bobbin (21). The stepping motor controller (102) controls the drive portion (200) to align the position of the unwinding side end of the yarn feeding bobbin (21) with the target position set in advance based on a detection result of the chase portion detection sensor (74).

Description

technical field [0001] The present invention relates to a take-up unit for unwinding yarn from a yarn supply bobbin and winding it onto a take-up bobbin. Background technique [0002] A yarn winding machine is known in which a plurality of winding units are arranged in parallel to wind a yarn unwound from a yarn supply bobbin onto a winding bobbin to form a package. In order for the winding unit to wind the yarn unwound from the yarn supply bobbin into a good winding package, it is preferable that the positional relationship between the yarn supply bobbin and the yarn guide disposed directly above the yarn supply bobbin be constant. As its yarn guide, an unwinding auxiliary device is known, which is formed on the unwinding position where the yarn of the yarn supplying bobbin is unwound by a cylindrical balloon limiter. to adjust the air circle. [0003] However, yarn supply bobbins of various shapes and inner diameters are supplied to the winding unit depending on the type...
