Design of Automatic Pharmaceutical Filling Control System Based on PLC
By using Huichuan PLC as the main controller,the automatic drug filling control system was designed and opti-mized to improve the speed and precision of the drug filling production line and ensure the high quality requirements of stable drug composition ratio.Based on the demand analysis of the filling process,the paper determines the PLC I/O distribution and con-trol flow,and improves the design by optimizing the PLC program and touch screen configuration.The operation practice results show that the improved and optimized control system can increase the production speed,increase the stability of the proportion of product components,reduce the failure rate,improve the filling quality,the system runs more smoothly,and the production effi-ciency is greatly improved.
