Abstract

A bobbin aligning device (6) changes the direction of a yarn feeding bobbin (3) in which a yarn is wound around a cylindrical winding core (4) having a bottom portion (4a) and an upper portion (4b) having a smaller diameter As the bottom portion (4a). The coil aligning means (6) includes two winding core guide paths (63) formed in an inclined manner. Each of the guide paths (63) has a bottom region (71) and an upper region (72). The receiving area (71) at the bottom of the area area passes through the upper area (4b) of the winding core (4) and receives the lower area (4a). The upper area-side receiving area (72) is located downstream of the receiving area (71) on the ground area side and receives the upper area (4b). The receiving area (71) on the base area side is designed in such a way that a receiving surface (84a) for receiving the end of the winding core (4) can be opened on the lower side.

Description

technical field [0001] The present invention mainly relates to a yarn supply bobbin direction changing device for changing the direction of the yarn supply bobbin. Background technique [0002] Conventionally, in a bobbin supply system for supplying yarn supply bobbins to each winder unit of an automatic winder, it is known that the base (side that can be mounted on the conveying tray) of the individualized yarn supply bobbins faces Bobbin direction changing device that makes it fall down. Japanese Patent Application Laid-Open No. 2014-25191 discloses such a bobbin direction changing device. [0003] Japanese Unexamined Patent Application Publication No. 2014-25191 discloses a device for changing the direction of a bobbin or bobbin. In this device, there are provided two accommodating sections including an intermediate chamber for accommodating one of both end portions of the bobbin (bobbin). The intermediate chambers are each set to a size such that the bobbin front end ...
