PLC Operated Colour Based Product Sorting machine

Manual sorting requires excessive effort and takes time, while automated sorting makes it possible to sort items quickly and efficiently. Production and packaging systems widely use the sorting method of product lines as a bridge. Industries have been sorting processes to arrange the materials of their items according to the requirements to decrease labour and increase overall accuracy. We have developed a S71200 PLC-based sorting system to demonstrate this sorting system, where we use electro-magnetic actuators with TCS2300 colour sensor to automate the whole system. The system consists of a conveyor belt to carry items and a colour sensor to sense the product’s colour form, and the system will then use 2 electromagnetic actuators to actuate and drive the product at its respective collection station. To identify the colour of the object moving on the conveyor belt, a colour sensor was used. The colour sensor transmits a particular signal to the PLC as soon as the appropriate colour is detected, which, in turn, operates the corresponding electromagnetic actuator to force the product out of the respective station. We can completely automate the sorting system in this way. In parallel processing industries, the sorting of these goods is very difficult. A consistency issue is created by continuous manual sorting. For controlling the overall operation, PLC is used as a master controller and Arduino as a slave controller. The colour identification method is based on the frequency analysis of the colour sensor’s output. This will fulfil the requirements of higher output and accurate performance in the field of automation.
