A consumer product manufacturer was experiencing problems with inconsistent placement of bottle inserts.Standard photoelectric sensors checking for inserts would often pass units that were not fully seated, resulting in frequent line shutdowns to adjust sensors. Sensor re-positioning also hindered job changeovers.
A vision sensor was installed. The part finding sensor identifies a reference feature on each bottle. This feature is used to locate where the insert should be visible. The Vision sensor then uses a pattern sensor to inspect for the insert placement. Use of the part finding sensor to locate the inspection point provides consistent, reliable readings even when the bottle position varies.
Quality, yields and scrap costs were improved by reliably identifying missing inserts. Its part finding capability and ability to save settings for different jobs minimized setup and changeover times. Downtime was reduced by eliminating frequent sensor adjustment.
