Winders
are used heavily in textile manufacturing, especially in preparation to
weaving where the yarn is wound onto a bobbin and then used in a
shuttle. Ball winders are another type of winder that wind the yarn up
from skein form into balls. Ball winders are commonly used by knitters
and occasionally spinners.
Automation winders
Winders have a center roll (a bobbin, spool, reel, belt-winding
shell, etc.) on which the material is wound up. Often there are metal
bars that travel through the center of the roll, and are shaped
according to their intended purpose. A circular bar facilitates greater
speed, while a square bar provides a greater potential for torque. Edge
sensors are used to sense how full the center roll is. They are mounted
on adjustable slides to accommodate many different widths, as the width
increases as the center roll is filled. The sensitivity of the sensor
depends on the required speed of operation.
Main functions of AC Inverter Nietz for Winders:
1、broken yarn from the stop function Hall fault
detection function: When the Hall element failure, the inverter for 5
seconds can not receive the pulse signal, the inverter automatically
shut down and display the prompt message.
2、stepless speed control function, suitable for elastic
yarn, but also to prevent the impact of the yarn surface pull off.
3、with PI adjustment function, can achieve closed-loop constant linear speed control function.
4、at the
same time also has a full stop, full yarn instructions, power-down
memory function and the starting frequency, the termination frequency
setting function, allows you to more easily control the winding machine
precision operation.
5、Constant linear speed control, is based on the diameter
of the pressure roller PI control of the spinning speed of the roller to
constant speed, constant speed to achieve the purpose of the pulse Hall
sensor mounted on the roller.
6、Frequency
increasing speed needs two frequency converters, one inverter drives
the spinning motor at constant speed, another inverter uses speed
increasing speed control over feeding motor to feed yarn, which can
improve the spinning efficiency.
7、Three kinds of tension adjustment control: through the PI
for tension adjustment; voltage decreasing tension adjustment; external
control to adjust the tension. Tension control is mainly to control the
tension of the yarn, if the tension control is good, spun yarn can be
moderate elastic.
8、During
operation, the current spinning length can be displayed cyclically, and
the spinning length and current running frequency can be set. The use of
the products produced by the appearance of spindles, winding capacity,
suitable for the production of the drum-type and tight-cylinder.
