Inspection units

Two additional cameras inspect the bottle base from below. One camera station uses bright field imaging to inspect the bottle base with the help of a special , motor – adjustable lens.

To back it up, a dark field imaging inspections, which is particularly suited to detecting fragments of glass , is also carried out. Foreign matter floating in the beverage is detected by a camera directed at the body of the bottle illuminated by transmitted light.

This module corresponds to the sidewell inspection device installed in the empty bottle inspection machine Linatronic 712-M2.

Fill level and closure inspection

A camera and an auxiliary system of mirror lenses provide two views of the neck and closure sections. The telecentric lens allows an optimum angle for monitoring the filling volume and the closure of the bottle . Crowns can be inspected for slanted application , damage, and incorrect rolling on. The absolute camera resolution per pixel is 0.25 mm.

Verification of the closure design

A camera inspects the container closure from above. At least 20 different closures can be distinguished , and containers with wrong, damaged, or faulty-printed closures can be detected accurately.

LED lighting

All camera stations are illuminated by light-emitting diodes (LEDs) . They feature even light distribution, low space requirements , long service life, and reduced power consumption. As they create very little heat, fans are not required in the illumination units.
