Present invention discloses an improved grading machine for grading small sized irregular objects which provides distinguished elements like reverse roller pairs assembly, a rotating drum having multiple numbers of contoured holes enabling faster pick up and dropping of the objects synchronous to the convey or motion, multiple imaging systems having multi-vision system along with multi wavelength lighting system, multiple transparent cups, an energizer assembly and an embedded intelligence system which remembers the position of each object thereby directing controlled opening of each cup bearing objects. These elements function collaboratively with one another making the placed objects fall into different collecting chutes, thus categorizing them according to their same properties based on same size, color, shape and surface finish. Present invention also discloses a process for grading small sized irregular objects. The invention is aimed to increase the grading efficiency of the improved grading machine using the disclosed process of grading irregular or uneven objects according to their size, color and surface properties in a rapid, practical, accurate, and satisfactory manner using electronically controlled non-contact mechanism. |
