Application Spotlight
Vial Cap Inspection
In other applications using a similar setup the Sharpshooter veries
other product attributes such as liquid ll level in the vials. The output
logic can then be used to determine which attribute failed and a
different output is activated for each failure. This way the control
system can direct the vial to separate reject stations, depending on
the failure.
During inspection, the Sharpshooter simultaneously veries that
the cap is present and is the correct cap. Live images taken during
inspection are compared to a known “good” image that is stored
in the memory of the sensor. The sensor compares the two images
and determines pass/fail of the vial currently being inspected. The
360° Pattern Match Tool is used to locate the vial within the region
of interest then moves the inspection tool to align with the vial’sposition. If the Brightness Tool detects the cap is present and is
correct, the vial passes on to packaging. If the Brightness tool does
not detect the cap, the vial is rejected.

They say, “timing is everything”. This catch-phrase has never been more true than for today’s production lines, where eliminating errors and processing
products at break-neck speed means more dollars for your company. Balluff’s UltraFrame™ self-contained thru-beam and Sharpshooter® vision families in
combination is one example of how sensors can work together to speed up the production line while improving product quality with automated error proong

In this application, a C-shaped UltraFrame thru-beam sensor and
a Sharpshooter vision sensor are used to inspect the medical vials
after the capping process. As the vials pass through the beam of
the UltraFrame, its output triggers the Sharpshooter upstream to
take a picture of the vial and initiate inspection. This is done by
using the built-in trigger input on the Sharpshooter. A backlight is
necessary in creating higher contrast for the image, which helps theSharpshooter inspect attributes with a higher degree of reliability.
