Designing and assembling of PLC based laboratory trainer for automated production system (APS)
(UMT, Lahore, 2020) Muhammad Aanish Raza and Amir Iqbal
The sole objective of our proposed project is to design and assemble PLC-based laboratory trainer for automated production system. We design a laboratory trainer which replicates the basic processes of deep freezer foaming injection. A working prototype has been developed to demonstrate how an automated production line for applying PU insulation in “Deep Freezers” work. Applying PU insulation is performed under the employment of PU filling equipment and this operation is extensively used in many industries that produce refrigerators. Under the scope of this project, the process from start to end is controlled by using an electrical controller device called PLC. PLC is considered as the central command unit of the entire system. Dc gear motor has been carefully chosen for well performance for the conveyor system. Infrared and Bluetooth sensor are best utilized to detect the relative position of the jigs. Temperature control and water level sensors and load cells are used. Under the current project scope, we have used limited quantity of sensors to keep the overall cost under budget. Programming of the plc is done in ladder logic. Plc is combined with the Arduino to reduce cost of the PLC. PLC is used to send and receive signals to Arduinos which perform different operations at different sections.
