Abstract


From the history of the modern spinning method, we can draw an important conclusion, namely the development of modern spinning technology, innovative methods of twisting and spinning textile science and technology to promote a new stage. The twisting method substantive reform is the core of the reform of modern spinning method. The twisting method has been traditional single twist to three or four times TWISTED. With the development of high power twisting method, based on high-powered twisting method twister follow. The new twister is the principle of high-powered twisting fiber yarn efficient twisting yarn processing equipment. Twisting by improving the situation by force of the fibers in the yarn of the yarn structure is changed, certain physical and mechanical properties, thereby improving the quality of the yarn. Twisting has a very important impact on the quality of the post-processing of yarn and fabric quality. Of twisting traditional machine equipment can not meet the demand. The twister of drive and control system is the core of the twisting device. Based on the survey results at home and abroad twister drive and control technologies, combined with the current trend of Electrical Transmission and computer local bus technology development, design the new twisting machine based on PCI bus drive and control system. Four motor drive system using multi-motor drive system. On the basis of the principle of high-powered twisting, the use of the analytical method for multi-motor drive system of the new twister motion analysis, to establish an appropriate mathematical model for multi-motor drive system, the integrated use of AC servo technology, frequency conversion technology and PCI local bus control technology and other advanced mechanical and electrical integration technology combined with the twisting process theory to design a reasonable control system, program-controlled spindle rotation rod reciprocating motion of the the cheese winding and yarn. Control system software part of the Visual Basic programming language to implement modular design, according to the technical requirements, friendly interface input yarn twist, twist to the winding angle and the main motor speed and other parameters, PCI board is called by the main program the dynamic link library card, the program calculates, converts a parameter to the control signal to drive the movement of the motor and the implementing agencies to complete twisting, winding, anti-stacked, anti-hard edges and twist transformation functions, are defined twist yarn . Precise twisting and winding process to complete the on-line monitoring and other functions of the yarn twisting and winding. The new twister transmission and control system advantages are: simple mechanical structure is conducive to safeguarding and maintenance; shorten the transmission line, reduced power consumption, low failure rate; easy to control, suitable for small batch production of many varieties; software system maintenance man-machine interface is easy to operate, program portability. Bus technology twisting machine control system to improve the technological content of the twister, added value and market competitiveness.
