基于PLC的三伺服枕式包装机控制系统设计

Design of Control System of Three Servo Pillow Type Packaging Machine Based on PLC

目的为了提高枕式包装机的自动化程度,提升其控制系统的通用性和可移植性。方法系统采用欧姆龙PLC CPU-CJ2M和运动控制模块CJ1W-NC414作为控制系统核心,配合伺服系统以及光电传感器等先进技术,实现包装机三轴的同步控制。温控部分采用CJ1W-TC001温度控制单元实现包装机横封和纵封的温度精确控制,并通过威纶TK6050IP触摸屏对整个控制系统进行实时监控、参数设置以及在线显示。结果该控制系统成功实现了枕式包装机的全自动控制,以及运行状态监控、包装参数设置。结论该系统成功应用于三伺服枕式包装机中,提高了包装机的包装精度、速度以及自动化程度。

The work aims to improve the automation of the pillow type packaging machine and enhance the univer- sality and portability of its control system. With Omron PLC CPU-CJ2M and motion control module CJ1W-NC414 as core of the control system, and in combination with such advanced techniques as servo system and photoelectric sensor, the synchronous control over the three axes of the packaging machine was achieved. As for the temperature control, CJ1W-TC001 temperature control unit was adopted to achieve the precise temperature control over the horizontal and vertical sealing of the packaging machine. Meanwhile, Weinview TK6050IP touch screen was used to monitor in real time, set the parameters of and online display the entire control system. The system successfully achieved the automatic control over the pillow type packaging machine as well as the monitoring of operating state and the setting of packaging parameters. The system has been successfully applied in the three servo pillow type packaging machine, with which the packaging precision, speed and automation of the packaging machine have been improved.
