伺服控制多梳经编机生产速度的影响因素分析

An analysis on the factors influencing the producing speed of the servo-controlled multi-bar warp knitting machine

阐述了交流伺服控制花梳横移系统的原理。分析了影响生产速度的主要因素,在经编机主轴横移角度一定的情况下,伺服控制多梳经编机生产速度主要由横移时间决定,横移时间的长短与伺服参数的优化程度、电机的响应性和一次横移的针距数密切相关。适当的伺服系统响应性是满足多梳经编机横移系统"停止→运动→停止"运动特性的关键,对多梳经编机生产速度的提高起着决定性的作用。花型组织一次横移最大针数决定横移该针距所需的脉冲数和横移时间,它的大小对伺服控制多梳经编机生产速度的提高有一定的影响。

This paper introduces the principle of the pattern guide bar's shogging movement controlled by the AC servo -motor,and analyzes the factors influencing the producing speed,i.e.,under the condition of the constant shogging angle of the machine's main shaft,the producing speed of the multi-bar warp knitting machine controlled by the AC servo-motor depends on the shogging time,which is closely related to the optimization of the servo-motor,motor's response and the number of pitches at one shogging. The appropriate response of the servo-motor is the key to realize the 'Stop-Move-Stop' task of the shogging system on the multi-bar warp knitting machine,which will determine the producing speed. The maximum number of pitches at one shogging will determine the required number of pulses and shogging time,and thus influences the machine's producing speed.
