变频技术在烟库摆动电机速度控制上的应用

Application of Frequency Conversion Technology on the Smoke Library Rotary Motor Speed Control

近年来,在烟草行业中为保证烟支质量,降低烟支空头率,卷烟机HCF部分烟库摆动轴的摆动速度的控制方式逐渐成为研究重点。文中应用先进的自动控制理念,成功地将变频调速技术应用到电机速度控制中,可实现两种速度控制方式:一种是烟库摆动电机的速度与主机速度跟随,即自适应匹配速度;另一种是根据生产工艺人为设定匹配速度。文中提出的匹配速度控制方法,可解决摆动驱动电机定速问题,成功实现了摆动速度随机性,有效降低烟支空头率与装盘中的掉烟、乱烟现象。

In recent years, the tobacco industry, cigarette in order to ensure quality, reduce cigarette short rate, cigarette smoke library HCF part of the swing speed shaft swing control approach is becoming a research focus. This application of advanced control concepts, successfully applied to the frequency control technology motor speed control, speed control can be achieved two ways： one is the smoke library swing motor speed and speed of the host to follow, that is adaptive matching speed; the other is the artificial production process according to the speed of matching. Propose a control method of match speed, to solve the problem constant speed drive motor swing, swing speed was achieved random, effectively reduce the short rate of plate filling empty cigarette out in the smoke, chaos cigarettes.
