Abstract
- Sting paper into compatible grades is a necessary step before recycling. Current methods of manually sorting are tedious, slow, andexpensive. High-speed automation of the sorting process will improve the cost efficiency and increase the amount of paperrecycled significantly. Correct identification of the sample in real-time before the sample reaches the actuation stations till remains a challenge because different types of paper and board samples are mixed in a waste stream, and have a lot of variation in terms of color, chemical composition, coating, and printing in black and white and color to different degrees. This primarily is because of a lack of satisfactory sensors and sensor fusion algorithms for sample identification in real-time. In this paper, we identify key parameters that must be measured, discuss a sensor system design, and describe integration of the output from sensors to interpret the type of sample using a fuzzy inference algorithm. Results show that the sensor system proposed is capable of identifying the samples at 90% accuracy compared to manual identification. The sensor system can be integrated onto a conveyor and a ctuation system for automated sorting. [ABSTRACT FROM AUTHOR]
