Design of The Control System of The Automatic Medicine Packaging Machine Based on PLC
Abstract: Industrial automation is becoming more and more advanced, and developing gradually towards the intelligent direction. In order to make the medicine packaging machine can be achieved from packaging production to produce qualified packaging product, the design selected FX2N-48MR Programmable Logic Controller manufactured by Mitsubishi in Japanese, as the main controller of automatic medicine packaging machine. Hardware circuit of PLC and the motor drive circuit are designed, and the control procedures of pharmaceutical packaging machine is compiled through the simulation software of GX Developer. The automatic medicine packaging machine not only can realize the manual operation, but also can achieve single step, single cycle and continuous operation of automatic control. Finally the simulation experiments verify the feasibility of the design, and the automatic control for pharmaceutical packaging machine is realized.
