The existing smart sensor did not have the tools to determine if label placement was out of spec. Quality Department requested the ability to make sure that the Lot/Date code is present.
The line was moved from another facility to a local one, and no documentation could be found. The existing controls system was reverse engineered, and the vision camera was upgraded to a Cognex InSight that mimicked the old system. Retrofit required the removal of some of the existing material handling components, which were removed, modified, and installed over a long weekend. The system was successfully brought online for the start of production.
Inkjet printer applies a lot and date code on round vitamin bottles. Jams or other printing issues can make the lot or date code unreadable.
Smart Camera was added to the system downstream from the Inkjet printer. System was presented with multiple instances of character from 0 - 9 and trained. PLC pushed the current Lot/Date code to the camera and the Smart Camera verified that it was a match.
