STABLE DETECTION OF PACKAGING
WHEN LOT CHANGES
With increasing diversified product packages, there are cases where the packaging colors differs
from lot to lot. This may result in false detection. OMRON brings innovation to manufacturing sites
through automation with "integrated," "intelligent", and "interactive" concepts with our new color mark sensors.
Challenges Faced When Packaging
Color Varies From Lot To Lot
In cases where the colors of packaging materials vary from lot to lot,
false detection of color mark could occur if parameters are not adjusted. This could lead to
equipment stoppage.
In such cases, it can be difficult to determine the root cause, resulting in
decreased productivity and time lost from troubleshooting.

RGB Data Transmission Function
RGB information for color marks and backgrounds of each lot is transmitted to a host to be deciphered.
This information is then managed with a database, making it possible to set optimal thresholds and identify causes quickly if a problem arises.

This information is then managed with a database, making it possible to set optimal thresholds and identify causes quickly if a problem arises.
Previously, setting threshold during commissioning required the involvement of a technical expert.
With the data transmission function, optimal setting is achieved simply by registering the RGB
ratio of a packaging.
When the sensor makes a false detection, values can be easily checked to determine if the reading
error is due to the color variation in lot changes. This makes it easier to troubleshoot and
resolve such error.

Test Parameter Support Function
The test parameter support function allows users to determine whether accurate detection is
possible for packaging designs in the prototyping stage.
Package designers and production engineers are able to use quantified RGB digital data to discuss
the designs. This allows them to reach a quick decision on which design to use, shortening lead time
from design to production line commissioning.
