随着食品包装行业的飞速发展,对类似枕包机这样的机械提出的要求是提高包装速度与精度,全面包装品规格,操作趋于人性化以及售后维护成本降低。根据枕包机的工艺不难看出,其控制重点在于送料、送膜以及横封横切轴三轴的配合,因此从第一代枕包机发展至今,主要就是对这三轴的控制进行改进以满足行业不断提升的要求,从低端到高端、从机械控制为主到电气控制为主,枕包机控制的发展主要经历了以下几个阶段:
阶段一:单变频
使用一台变频器加一台交流电机来工作,为了成比例的同时带动横封刀(加输送机)跟包装膜,需要一台无极变速箱来根据不同的膜长调节膜轴的速度。从而实现了两路速度的输出,但是无极变速箱会随着使用时间的增长出现磨损影响使用精度,因此有他的局限性。横封刀的运行曲线是由机械凸轮来实现的,因此机械结构复杂,传动机构多。
阶段二:单变频+单伺服
使用一台变频驱动横封刀(加输送机),一台伺服驱动包装膜,取消了无极变速箱。各部分运行独立,由PLC控制器协调两部分速度。横封刀运动轨迹仍有机械凸轮实现。
阶段三:双伺服
原理同单伺服+单变频,但其控制精度进一步提高。
阶段四(目前最先进的控制方式,本文介绍重点):三伺服
三个伺服分别驱动横封刀、包装膜、供料输送机,横封刀的运行轨迹完全有伺服来实现,取消机械凸轮,简化了机械结构。三部分的运行速度需要有高性能的控制器来控制,因此对于控制器的要求比较高,经过试验固高的CPAC控制器能完成这项功能,并且能提高包装速度速度。
