YARN WINDING MACHINE AND CONTROL METHOD FOR BOBBIN POSITION THEREOF
Document Type and Number:
Japanese Patent JP3211541
PURPOSE: To prevent a yarn layer from protruding in the width direction of this machine at the time of replacing a bobbin, by mounting a holding mechanism which holds a bobbin holder by moving plural bobbins as necessary independently respectively at a prescribed route when bobbin changing-over at the time of full package or yarn winding is carried out.
CONSTITUTION: A holder holding mechanism 23 is mounted, which moves two bobbins 24, 25 independently respectively by a circular orbit 51, to move the winding bobbin 24 downwards and inwards gradually from a winding start position P2 on the side and rotate the waiting bobbin 25 so as to be brought into no contact with the moving winding bobbin 24 and a lifting box 28. In the course of yarn winding start to doffing, it is possible to reduce an installation pitch without protruding a yarn layer 16 in the width direction from a machine body 25. That is, it is possible to attain reduction of an installation space in a yarn system.
