A collaboration between SICK and AutoCoding Systems has resulted in the launch of the first fully-automatic smart vision inspection system for printed coding and marking on food, pharmaceutical and other consumer goods packaging.
The 4Sight Automatic Print Inspection System achieves significant savings in day-to-day production stoppages for producers.
A breakthrough innovation achieved in the AutoCoding 4Sight software, operating on SICK’s Inspector P smart vision camera, enables direct closed-loop communication of the printed message from any brand of printer using standard inkjet, laser or thermal transfer technologies.
The application, one of the first to be developed using SICK’s AppSpace software platform, has delivered an error-proof, high-speed inspection system for printed codes such as dates, batch and line numbers.
The new direct communication concept cuts out costly ‘nuisance stops’ and the time-consuming set-up that conventional vision systems need to be taught thousands of images and fonts, as well as the context of the surrounding packaging design affecting the inspection.
“Working with SICK and using the power of the SICK AppSpace development environment, we were able to draw on the strengths of AutoCoding to think about print inspection systems in a completely new way,” explains Mike Hughes, Managing Director of AutoCoding Systems.
“The result is a directly networked connection between the printer and the smart camera, coupled with the 4Sight software’s unique ability to self-optimise the code inspection process.”
“As the artificial intelligence is already pre-trained in the application, the AutoCoding system knows exactly the printed message it is looking for. So, the system adjusts automatically when the printer changes to a new job.
“There’s also much more opportunity to finesse the vision inspection criteria and avoid unnecessary line stops, because there can be no false reads as a result of the packaging background, or due to natural variation in the location of the printed code.”
Powered by SICK AppSpace, onboard the high-resolution SICK Inspector P smart camera with no need for a lineside PC, the 4Sight software simultaneously checks whether the printed code is correct, present and legible.
Users have the flexibility to define what is classed as a ‘good read, bad read or no read’ on a per product basis.
However, there’s no need to teach fonts, configure features or regions of interest on the packaging, or for fixturing against an edge or logo. A simple, user-guided self-set up process configures the optimal camera settings.
Enabled by the high-resolution and processing power of SICK smart vision technology, the solution is capable of processing inspection images with extremely short cycle times.
It operates at increasing line speeds, including high-speed applications such as bottling and canning lines.
