Abstract: In the era of Industry 4.0, the application of automation in production has become an essential trend to increase productivity, reduce costs, and improve accuracy. This paper presents the design and implementation of a model for sealing caps using a Siemens S7-1200 PLC combined with pneumatics and stepper motors. The system includes a conveyor, a rotary table, a suction–sealing mechanism, and a control cabinet. The control algorithm is programmed in the PLC, and an SCADA interface is built for monitoring. Experimental results show that the model operates according to the principle and performs the sealing process, but the speed is still limited and the accuracy is not high. The study demonstrates the feasibility of automating the sealing process in packaging production lines.
Keywords: S7-1200; PLC controller; Cap sealing system; SCADA.
