ABSTRACT:
An inspection system for detecting excessive particulate matter in serially presented liquid filled vials. Vials are advanced by an in-feed star wheel, a rotating vial deck and an out-feed star wheel having the same number of vial locations and vial orbit speed. Along the vial deck orbit, each vial is successively clamped to a rotatable puck, spun momentarily to swirl the liquid therein, inspected for particulate content, and unclamped. Further rotating decks carry circumferentially arranged television cameras and light sources, respectively. Each camera looks radially inward, axially through an orbiting periscope and then radially outward to inspect a vial. Light from each light source passes radially inward and then axially to bottom light its vial. A separation unit enhances the camera video portion corresponding to swirling particles in the vial. A processor unit then detects particles in a window area overlying the swirling vial liquid by assessing the width along a scan line and occurrence in successive scan lines of a video disturbance and repetition of that disturbance in several successive scanning fields of the camera. A vial reject unit and a color CCTV monitor are provided. One or more separator-processor units and a monitor may be time shared by a plurality of cameras.
