PLC Based Automated Object Sorting System

In this advance era, automatic sorting is highly desirable in approximately every industry. Its main objective is to reduce human efforts and time which can ultimately raise its efficiency. However, perfect sorting machine is still in progress which should be flexible and compatible in design. In this work, the proposed sorting machine is able to corporate compatibility by using conveyer belt and proximity sensors to detect type of material i.e. wood, metal or plastic and also identifies size of material in three different ranges and finally sort the material separately in assigned basket by using pneumatic cylinder (controlled by Programmable Logic Controller (PLC)). The proposed multi sorting system is able to sort nine objects of nine different ranges are sorted with 100% accuracy within the time interval of 0.5 seconds. The proposed model could be implemented in any industry whose applications are mechatronics based engineering system. This model can also produce list of sorted objects through enabled sorting program commands.
