Method for controlling traversing device in conical cross wound bobbin winding device in textile machine, involves approximating value of modified conicity factor to value of conicity factor determined before designing bobbin

摘要

#CMT# #/CMT# The method involves driving a conical cross wound bobbin (5) by a bobbin drive shaft (9). Conicity factor is determined based on the provided bobbin geometry so that a rate of thread running speed is reproduced in front side of the bobbin to adjust the bobbin design according to the geometry of a conical bush (18). Modified conicity factor is adjusted for controlling a drive (14) to start passage of the bobbin. Value of the modified conicity factor is approximated to a value of the conicity factor determined before designing the bobbin during running condition of the bobbin. #CMT# : #/CMT# An independent claim is also included for a textile machine for performing a method of controlling a traversing device. #CMT#USE : #/CMT# Method for controlling a traversing device in a winding device, which is utilized for winding a conical cross wound bobbin on a conical bush in a textile machine (all claimed). #CMT#ADVANTAGE : #/CMT# The modified conicity factor is adjusted for controlling the motor drive to start passage of the bobbin, where the value of modified conicity factor is approximated to the value of the conicity factor determined before designing the bobbin during running condition of the bobbin, thus reducing the occurrence of variation in positions of the driven diameter of the bobbin. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a textile machine. 5 : Conical cross wound bobbin 9 : Bobbin drive shaft 10 : Traversing device 14 : Motor drive 18 : Conical bush.
