The design and development of Programmable Logic Controller-Based Coffee Packager was conducted at Silang, Cavite. The study generally aimed to construct and evaluate a Programmable Logic Controller-Based Coffee Packager that would automatically pack ground coffee. The PLC-based coffee packager comprised of software and hardware.
The hardware of the system was consisted of programmable logic controller circuit, relays, power supply, terminal blocks, pcb board dot matrix, proximity sensor, gauge #18 stranded wires, DC motors, brass rollers, conveyor belt, toggle switch, push buttons, circuit breaker, royal cord and the coffee packager. The software used to control the operation of the machine was Ladder Diagram. It was programmed in the PLC using the MELSEC software program provided by its manufacturer, the Mitsubishi Electric Corporation.
The Programmable Logic Controller-based machine for Coffee Packager can packed the desired pre-selected weight of ground coffee beans, however, the accuracy is less than 100%. The average percent error of weight was 14 percent in the trials made for 50 grams, 150 grams and 250 grams.
