This article introduces the application of the Zhishan G2 series servo system in the underwear machine and illustrates the key parameter setting of the servo driver.
1. Introduction
The computerized knitted underwear
machine adopts an advanced full-computer control system, which can alarm the
faults, illegal operations, and unsafe factors in various knitting processes, making
the operator safer and the knitting smoother. Computer knitting underwear
machines can weave out any style of underwear with natural, synthetic,
artificial, and other fibers and yarn materials. With the improvement of living
standards, the demand for computer underwear machines is increasing, and the
requirements are relatively increasing, so a lot of servo is applied on the
underwear machine.
2. Brief introduction of underwear
machine principle
The general structure of the underwear
machine knitting machine is mainly composed of yarn feeding or yarn feeding
mechanism, knitting mechanism, traction winding mechanism, transmission
mechanism, electronic control mechanism, and auxiliary mechanism. Customers can
process any kind of plain cloth, jacquard, and tissue forming garments and
various underwear craft patterns through the computer to process special
instructions at all levels of the organization. These instructions control the
needle selector and servo drive on the knitting machine, which can be adjusted
and density arbitrarily Adjust and weave all kinds of machines you want to
produce. Computer knitted underwear machine is mainly composed of a control
program, transmission system, complete device, loop number, loop setting
device, etc. Control program: Control the output through the self-developed
integrated circuit, and accept the program and data through the USB interface.
Transmission system: Adopt a servo motor and drive through a synchronous belt.
Complete device: adopt stepper motor independent control, each channel can
quickly change the density. Tuck device: It is composed of 8 tuck triangles and
is controlled by cylinder.
The appearance of the underwear machine
is shown in Figure 1:

3. Control requirements and functions
1). Servo high positioning accuracy; (requires
that each positioning error does not exceed 4 pulses)
2). It has the functions of normal stop and
emergency stop; (that is, the machine can stop quickly and steadily by pressing
the stop button or the emergency stop button when the motor is running, and can
start quickly and smoothly when it is restarted.)
3). Origin return function;
4). High-speed and stable operation; (Able to
cooperate with the feeding speed of the front-end filling production line to
realize the rotation speed of the rotary positioning mechanism can be adjusted
arbitrarily from 1 to 1000r / min.)
5). It can intuitively display the working
status and fault information of the servo on the man-machine interface;
6). Prohibiting reversal function.

Conclusions
Zhishan G2 series servo on underwear machines
has the advantages of fast response, high precision, low noise, high stability,
flexible operation, and so on. After testing the knitted underwear, all
indicators meet the requirements. At present, it has been widely used in the
seamless underwear machine industry.
