数字伺服和运动控制技术在纺织机械中的应用（Application of digital servo and motion control technology in textile machinery） Application of digital servo and motion control technology in textile machinery In recent years, with the enhancement of peoples aesthetic awareness and the improvement of living standards, high-grade yarn dyed fabrics have been more and more popular. Not only real silk, chemical fiber, artificial silk, cotton yarn and blended yarn can be used silk weaving, which prompted the bobbin dyeing process is widely used in yarn dyed industry. The general needs to be purchased before dyeing bobbin yarn winding into suitable for dyeing with pine cone for the next step, the loose type precision winder increasing demand. General domestic existing slack winding machine structure using single spindle centralized transmission mode, usually including winding, yarn and over feeding several movement by mechanical gear and cam mechanism, the winding process of all kinds of yarns of different equipment, difficult to adjust; the yarn guide mechanism is used in drum and rotating wing, easy to cause damage to some high-grade yarn; at the same time, due to the use of the mechanical transmission structure, winding speed is not high. At present this loose type winding machine has been completely adopts full digital winding structure of electronic gear and the electronic cam based on single spindle independent drive; winding, the transverse guide yarn, yarn superfeed, tension compensation adopts separate motor control, the relationship between movement of each motor can be set through the parameter description to yarn winding to deal with the various characteristics of the flexible process; the yarn guide traverse is the guide, commonly known as the rabbit head, the yarn winding damage is very small, especially suitable for high-grade yarn dyed yarn; also because the motor in the machine has no direct connection with the transmission, high speed and high precision motion control the software
