3.1 Applied range
It's a cone-to-cone winding machine can be used of various yarns such as cotton,wool,nylon,chemical filament, rayon, spandex and so on. Also according to the requirement , it can be used to combining two ply or three ply into cheese packages.
3.2 Yarn winding process
Put the raw yarn in the yarn seat under machine, the yarn through the yarn guide ring and yarn guide ceramic part of panel into tensioner, then through yarn detector and enter overfeed yarn device or constant tension device, at last via the yarn guide move back and forth to winding on the take up bobbin. According to different demands, some winder need through overfeed pulley, lubrication system, air jet when traverse.
3.3 Machine basic structure
Machine compose of three function part
·Motive power parts
Contain frequency converter( or brushless motor drive),sensor, electrical control box, operation element/executive component
·Winding structure part
Machine is single side working structure, adopt metal plate structure , each section is compose of four combine structure units
·Driving parts
Machine is single spindle individual drive, motor drive overfeed directly and take-up active winding cheese axis.
3.4 Winding unit structure
3.4-1 Yarn tension device
One tension method is weighted gate tension device, based on the different yarn, increase and reduce pressure to adjust the yarn tension, to get the good package from the stable tension.
Another tension method is constant tension controller, ensure the yarn tension precision, can make stretch yarn such as difficult to good forming to good forming shape.
Third tension method is automatically control tension of stepper motor, according to the tension requirement of pressure sensor to provide tension data as needed.
3.4-2 Yarn break automatic detection system
Adopt photoelectric or level type yarn sensor, send the signal to controller when yarn brake, also turn off the motor running automatically; At the same time, the signal lamp shining to prompt the machine have already stop.
3.4-3Overfeed device
Overfeed device use independent motor for synchronous operation. According to different yarn, overfeed ratio 100%-200% can be arbitrarily set, to make sure the winding forming beautiful.
3.4-4 Constant tension device
When adopt constant tension device, install a pressure sensor at top of constant tension. Constant tension device adopt a overfeed pulley which driven by a sensitive, independent drive motor. Yarn wind this overfeed pulley through pressure sensor and reach take up bobbin, after set the pressure, through sensor's signal to control. When over pressure, overfeed increase the speed to feed yarn; When pressure are smaller, overfeed decrease the speed to feed yarn, to reach the yarn tension consistent and the good yarn forming.
3.5 Electronic yarn guide forming device
Via positive inversion of stepper motor, adopt wire rope to drive and take fixed yarn guide head, in the running of the motor, making yarn guide head do back and forth at high speed winding and forming.
We have research and development the control system of yarn guide winding forming of stepper motor, realize yarn guide forming automation:
With the help of Wuhan Textile University, we have research and development the control automation system of yarn guide forming of stepper motor; This system can make precise control the positive inversion distance of the stepper motor, the running can reach 1200 rounds per minute, we can change path freely in the movement path at the same time. So that the winding forming can according to the need density, soft side, different retract side angle, forming length etc.. To realize the forming electrical automation.
