Winding machine for winding thin threads on spools, has positioning unit for adjusting position of changing devices in spool spindle axis direction depending on detected measuring value from sensor

摘要

#CMT# #/CMT# The machine has traversing devices (3) to change threads (1) to be spanned in a spool axis direction. A pressure roller (4) fits the changed threads at a spool (8). A sensor (17) e.g. triangulation sensor, directly or indirectly detects position or length of tubes (9). A positioning unit (20) adjusts position of the traversing devices in a spool spindle axis direction depending on a detected measuring value from the sensor. The traversing devices are formed of traversing wings that are rotated opposite to each other, where the traversing devices are attached to a common traversing plate (21). #CMT# : #/CMT# An independent claim is also included for a method for operating a winding machine for winding a set of thin threads to a set of spools. #CMT#USE : #/CMT# Winding machine for winding thin threads on spools. #CMT#ADVANTAGE : #/CMT# The sensor directly or indirectly detects the position or length of tubes, and the positioning unit adjusts position of the traversing devices in a spool spindle axis direction depending on a detected measuring value from the sensor, thus increasing reliability of thread catching on the tubes with certain length tolerance of the tubes in a cost-effective manner, while extending spectrum of the acceptable tube length tolerances. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a winding machine. 1 : Threads 3 : Traversing devices 4 : Pressure roller 8 : Spool 9 : Tubes 17 : Sensor 20 : Positioning unit 21 : Traversing plate.
