The cap inspection system (CIS) is designed to detect defects in the polymer seal of metal caps. The seal ensures tight closure of metal containers.
Common defects of a polymer seal: foreign particles, tears, jams, etc.).
The detectable defect size is 1.0 mm or more.
Inspection speed is 1 cap per second.
When a defect is detected, the CIS generates a digital signal to reject the cap with a defective seal.
The sensitivity limits of the CIS rejection criteria may be configured and adjusted.
To ensure a contrast and glare-free image, a special dome light was developed and made for CIS to fit the sealed cap size.
