机械控制在现代纺织工业的应用外文文献翻译、中英文翻译、外文翻译
Machinery control applications in
the modern textile industry
Some years, as people more conscious of the aesthetic and living
standards, high-grade yarn-dyed products are increasingly popular. Not
real silk, chemical fiber, rayon, cotton yarn, also can be blended and
Silk weaving, dyeing bobbins which led the industry in the yarn is
widely available. General yarn before dyeing tube blanks need to be
purchased to suit the yarn package dyeing contact with the "pine-style
cheese" for the next procedure to use, so slack increasing demand for
precision winding
Existing domestic slack winding machine structure is generally
focused on single-spindle drive mode, usually including winding, yarn,
over-feed, such as several sports, the use of mechanical gears and
cam completion, for a variety of yarns of different winding process,
equipment is more difficult to adjust; yarn organizations to adopt a
grooved drum and rotary wing, for some high-end yarn is easy to
produce injury; the same time as the structure is used in mechanical
transmission, winding speed is not high. This pine-style winding
currently abroad has been completely based on electronic gear and all
digital electronic cam winding structure, namely, the independent single
spindle drive; winding, traversing yarn guide, yarn over-feed, tension
compensation are used separate motor control the movement of the
relationship between the motor can be described by parameter setting,
flexible response to various characteristics of the yarn winding process
needs; traversing yarn guide used the "yarn guide", commonly known
as "rabbit head" , damage to the yarn is very small, especially for high-
grade yarn-dyed yarn winding; In addition, as the motor drive there is
no direct mechanical connection, combined with high-speed precision
motion control software algorithms, can easily achieve high precision
cross-winding, winding speed of winding is much larger than
mechanical slack, greatly improving the efficiency of the winding
Beijing and Li Technology Co., Ltd. through the motor and domestic
well-known textile machinery group co slack for precision winding
process characteristics, in their many years of accumulation of the
servo and motion control technology, based on the successful
development of the country for the first time round with their own
Intellectual property rights of high-speed precision slack winding
electrical control program. The scheme has good performance and low
cost, greatly enhancing the domestic slack winder automation level, the
major technical indicators have reached the level of similar foreign
equipment.
System control program profiles
Single-spindle control, for example, a system control program
shown in Figure principle, traverse the motor shaft connected to a wire
wheel, wire wheel through the positive and negative spin-driven
fastening the wire yarn guide and move around, to achieve cross-yarn
Fixed cable movement; winding yarn tube direct-drive rotary motor, to
achieve the yarn winding movement, the horizontal motion and the
synthesis of the two movements after winding yarn showed the shape
of a spiral wire wound on bobbins surface back and forth . Tension
compensation and over-feed motor is mainly used to control the motor
in the process of yarn winding tension.
The yarn guide traverse the program uses a motor through the unique
design of the ultra-small inertia servo motor, motor winding, and over-
feed is also used in custom designed high-speed brushless DC motor,
the tension motor uses a common step motor. Figure in the "single-
spindle control driver" is and the benefits of the motor development in
its own all-digital AC servo drive, based on the embedded high-speed
electronic yarn winder precision motion control algorithms, winding
brushless motors speed control and special yarn tension control
strategy based motor drive control system. The whole system is simple,
functional and communication through the adjustment of the keyboard
or the "single-spindle control driver" parameter can be easily set up the
internal memory of yarn winding forming the geometric parameters (full
tube diameter, to close edge amplitude, etc.), winding the line speed ,
the winding ratio, traverse the length of yarn, hard-edged trim tube
differential amplitude, differential cycle, the cam curve of the differential
parameters, along with RS232, RS485, CAN bus communication
interface of three, can easily complete networked multi-spindle control,
the full realization of flexible digital winding. The main technical
parameters are listed below:
Than the control winding 2.000 ~ 12.000;
Traverse to the acceleration of the servo motor for up to 8000r/s2,
