【摘要】：目的受色标印刷偏差、张紧力失衡、机械振动等因素影响,很难保证色标定位的准确性,为了提高枕式包装机色标定位精度,提出一种色标自动定位方法,并基于PLC设计相应控制系统。方法通过分析包装机械运行规律,详细阐述色标补偿原理。利用色标、刀位检测信号判断横封和纵封是否同步,并计算偏差数值。以横封位置为基准,通过调整纵封电机的脉冲频率和脉冲个数进行定位补偿。同时基于PLC搭建枕式包装机的控制系统,并介绍控制系统的硬件结构和软件设计思想。最后进行实验研究。结果切点位置均在色标点上,可以实现色标定位。结论该控制系统和方法能够满足包装机械对定位精度的要求,提高了包装机械的包装精度、效率,降低了次品率。
[Abstract]:In order to improve the accuracy of color standard positioning of pillow packing machine, an automatic localization method of color standard is put forward in order to improve the accuracy of color standard positioning, because of the influence of printing deviation, tension imbalance, mechanical vibration and other factors. Based on PLC, the corresponding control system is designed. Methods by analyzing the running rule of packaging machinery, the principle of color standard compensation is expounded in detail. The deviation value is calculated. Based on the transverse seal position, the positioning compensation is carried out by adjusting the pulse frequency and the number of pulses of the longitudinal seal motor. At the same time, the control system of the pillow packing machine is built based on PLC. The hardware structure and software design idea of the control system are introduced. Finally, the experimental research is carried out. Conclusion the control system and method can meet the requirements of positioning accuracy of packaging machinery, improve the packaging accuracy and efficiency of packaging machinery, and reduce the rate of defective products.
