Final answer:
Digital controllers improve the flexibility, accuracy, and reliability of conveyor sorting systems, and closed-loop systems offer real-time feedback and adjustments for increased sorting accuracy.
Step-by-step explanation:
The advantages of using a digital controller for sorting in conveyor systems include enhanced flexibility, accuracy, and reliability. Digital controllers can quickly process complex sorting algorithms and adapt to different types of objects, leading to improved sorting efficiency. Additionally, they can easily integrate with other digital systems for real-time tracking and data analysis.
Using a closed-loop system is typically better for conveyor sorting processes because it allows for continuous feedback and adjustments. This means that the system can correct any errors in real-time, thereby reducing the likelihood of mis-sorted items and enhancing the overall accuracy and reliability of the sorting process.
