包装机械电子凸轮关键技术研究与应用

Research and Application of Electronic CAM Key Technology in Packaging Machine

重点分析了电子凸轮功能在枕式包装机控制系统中的实现方法,利用智能高速型PLC、伺服系统与人机界面技术,去除原有机械凸轮机构,改由电子凸轮功能控制横封切刀,实现了柔性变速运转。方案解决了传统机械凸轮安装困难、响应滞后、量测性差等问题,使横封切刀的运动曲线可以即时改变。同时提出了一种新型色标追踪方法,采用色标和光电传感器对切割长度值实时反馈,提高了包装精度,降低了系统的响应时间。

Focuses on the electronic CAM function implementation methods in pillow packaging machine control system,combines PLC,servo system and Human Machine Interface technology, remove the original mechanical CAM,and now control horizontal sealing and cutting knife in variable speed rotating through the electronic CAM. This plan solved the problem in traditional mechanical CAM such as dificuh installation , lags in response, and bad measurement per- formance, made horizontal sealing and cutting knife sport curve can be instantly change. Meanwhile this paper puts for- ward a new color code tracking method and using color and photoelectric sensor to detect the feedback of packaging length in real time , in order to improve the packaging precision and reduce the system response time.
