Abstract
An opposed pair of inwardly facing radiant energy detecting sensors (20, 22) is positioned to sight on freshly formed glass containers (C) being conveyed on a side by side pair of conveyors (12, 14) to determine if any of the containers is misoriented from its desired orientation. Each sensor has a sharply focused fiber and lens assembly (24) that is focused to sense radiant energy in a cone of view no greater than 1°. A baffle (32) is positioned between the conveyors and in alignment with the opposed sensors, to isolate the sensors from radiant energy emitted by containers on the away conveyor.
