INSPECTION APPARATUS FOR FINE AND TRANSPARENT PELLET

摘要

The present invention relates to a pellet inspection apparatus for detecting contamination and discoloration of pellets (P) which are fine and transparent or milky-white and white (hereinafter referred to collectively as transparent) with high precision and speed. According to the present invention, a rotary absorption drum (3) is disposed between a conveyance belt (4) and a discharge part (2) for the pellets (P). A plurality of absorption openings are disposed in a row in an axial or circumferential direction in the circumferential surface of the rotary absorption drum (3) on which partition walls (3A) are disposed to partition the axial or circumferential rows of the absorption openings, only one pellet (P) being attachable to each of the absorption openings. At least one of each pair of neighboring partition walls (3A) between which an absorption opening is disposed is provided with a surface sloped down to the circumferential surface of the rotary absorption drum (3).
