In this advance era, 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)). Sorting can be done by using many ways like sorting of object according to their dimensions (height, length etc.), according to their colours, according to their weight, using machine vision (image processing), according to the material of an object etc. For example in Thermal Power Station electromagnetic sorting technique is used to sort ferromagnetic materials from coal. This project consists of two parts, first consisting of software that contains ladder logic programming which is used to program PLC that controls the whole process of the project step by step according to input data sequence. Second is the hardware part which consists of conveyors used to transport the objects, sensors used to sense the height (i.e. laser sensors) of the objects, electronic system used to sort the objects and motors to drive the conveyors. The use of sensors in the sorting process can ensure that the products are sorted accurately based on their height variation. The conveyor belt system can be used to pass the products before the sensors, and the PLC can make decisions based on the sorting logic.
