Method and apparatus for inspection of hot glass containers

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...

Beschreibung
Zusammenfassung:	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 DEG . 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.
