ABSTRACT:
A method and apparatus are disclosed for detecting and ejecting articles of different weights in a product and article stream, by varying the dwell and delay time in accordance with the color classification of the products and articles being sorted. The ejector dwell and delay times are determined by the weight of the products and articles, which can be identified by the percentage reflectivity of color wavelengths of interest.
