    PLC controlled colored pencil sorting mechanism
    (University of Management and Technology, 2013) Asif Javed; Muhammad Shaheer; Bilal Khan, Muhammad
    The purpose of the project is to provide a mechanism for color pencil sorting. Different techniques are used to sort different items in our daily life. With the advent of liberalization and globalization, it is necessary that industries explore methods of enhancing automation and productivity to acquire greater competitiveness. In this regard Low Cost Automation (LCA) is a technology that promises to be very useful for any kind of manufacturing organization. In this project, we have developed an automatic controlled system for sorting of pencils of different colors. Pencils that are moving on a conveyor mechanism have different colors. We have used image processing in MATLAB for taking image of pencil and finding color of pencil .After finding color of pencil special code of that color is sent to PIC microcontroller through serial communication .In PIC Microcontroller code is checked and signal is sent to PLC for timer controls. In PLC we have used timers, so that pencil whose color is checked comes in front of actuators, which are used for pushing pencil out from conveyor. It was also possible to complete this project without using PIC Microcontroller, but it was some extent costly because another module was required for PC to PLC serial communication.
