To tackle the pain points of traditional color sorting systems, namely low efficiency, high misjudgment rates, and excessive dependence on manual operations, this research has developed an intelligent color sorting system with Inovance PLC as its central control hub.By optimizing hardware layout, refining the color recognition algorithm, and conducting software programming and debugging, the system enables fully automated operation throughout the entire process, from material loading, transfer, and precise color identification to sorting and warehousing. Ultimately, it achieves the core objectives of continuous multi-batch sorting, low error rates, and unmanned operation, offering technical support for industrial scenarios related to color sorting.
