摘要
针对4边封包装机由于送膜轴和切刀轴的运动分离控制导致薄膜进给与切刀旋转不同步而影响了加工质量的问题,课题组基于EtherCAT技术原理搭建控制系统整体框架。设计一种电子凸轮曲线,实现追剪过程中执行机构间的速度与位置匹配;以EtherCAT为通信手段,满足执行机构间响应同步需求;另外对机械零位进行周期性补偿,弥补机械误差引起的加工误差。基于该系统实际加工袋长为200 mm的塑料薄膜,误差小于1 mm,且产品没有出现损坏情况。该控制方法能够满足4边封包装机的加工需求。
Aiming at the problem that the machining quality of four-side sealing packing was affected by the non-synchronous rotation of filming feeding and cutter due to the motion separation control of the film feeding shaft and the cutter shaft,the overall control system framework was built based on EtherCAT technology principle.An electronic cam curve was designed to match the speed and position of the actuator during chasing shear process.EtherCAT was used as the communication means to meet the needs of synchronization between the actuators.In addition,the mechanical zero position was periodically compensated to make up for the machining error caused by mechanical error.Based this system,the plastic film with a bag length of 200 mm was actually processed with an error of less than 1 mm and no damage.The proposed control method can meet the needs of the four-side sealing packaging machine processing.
