Title:
SPINNING YARN WINDING MACHINE AND CHANGING OVER METHOD FOR YARN FOR WINDING MACHINE
Document Type and Number:
Japanese Patent JP3132416
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the success rate of a yarn delivery from a full bobbin to an empty bobbin and to prevent the damage of a yarn at the time of changeover motion by shortening a time required until the yarn delivery at the time of changeover motion for changing over the winding and standby positions of two bobbin holders in a turret type spinning yarn winding machine.
SOLUTION: A yarn winding machine has changeover motion for changing over two bobbin holders to a winding position and a standby position, and in the case of delivering a running yarn arrived at a full bobbin to a yarn catching means provided at the end of the empty bobbin with the changeover motion, a yarn changeover guide 50 for moving the running yarn to arrive at the full bobbin toward the yarn catching means at the end of the empty bobbin is provided, and temporary stopping means 60, 61 for temporarily stopping the yarn changeover guide 59 at a position where the running yarn is positioned at the end of the yarn layer of the full bobbin are provided, and the running yarn is moved to the yarn layer end of the full bobbin before the completion of the changeover motion.
