    Design and fabrication of PLC based machine for metal detection and separation in packed food items
    (UMT Lahore, 2021-09) Roshan Jahanzaib; Syed Muhammad Hassan Shah; Adnan Saeed
    Food processing is one of the most widely recognized industry in the whole world. The safety of the consumers is the most prior one. This project is based on the metal containment or parts goes in the food due to wear and tear of the machine or any other issues related to the production. This project works on the removal of the parts that are present and can’t be detected by the human eyes. So, it’s a scanner that scan the food and separate the food that has metal parts in it. This technology is not being introduced nowadays in Pakistan but in the future, there will be such machines or technology that will work for welfare of the humankind. The focus of the project is to design a system and eliminate the metal parts. PLC was used in this project for controlling every action related to our requirements. Programmable Logic Controller (PLC) is costly, but it has the tendency of thousands of electromechanical relays. So, the function is to first detect the object present in front of proximity sensor and it passes the signals to the PLC and it will operate the conveyor with a DC motor then there is metal detector which will detect the presence of any metal and then one more proximity sensor that detects and give signals to the swiper and it swipes the faulty sample and if not, it passes the swiper and goes to final destination.
