Automatic inspection system for coding and marking
A collaboration between SICK and AutoCoding Systems has resulted in the launch of a fully-automatic smart vision inspection system for printed coding and marking on food and beverage packaging.
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. There is no need for a lineside PC, as the 4Sight software simultaneously checks whether the printed code is correct, present and legible.
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.
One of the first to be developed using SICK’s AppSpace software platform, the application delivers an error-proof, high-speed inspection system for printed codes such as dates, batch and line numbers. Set-up and downtimes are reduced, thus providing cost savings to producers.
The 4Sight Automatic Print Inspection System can be set up as a stand-alone system using all main printer brands, as well integrating with proprietary code deployment systems. It can be configured to connect with other devices, for example an encoder, and can be integrated with other systems e.g. to control a rejection system.
The 4Sight system can be set up to provide full diagnostic reports and event logging and will store and forward inspected images to the customer’s network location of choice. Feasibility studies, installation, integration, training and ongoing support are available through AutoCoding Systems.
“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,” said 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,” concluded Hughes.
Neil Sandhu, SICK’s UK product manager, imaging, measurement, ranging & systems added: “All too often we are called in to help production teams who have ended up disabling their vision systems altogether because of the nuisance caused by frequent, unnecessary line stops as a result of an overly-sensitive system.
“The problem is too complex for the operators to fix, so the vision system simply becomes a white elephant. As a result, the manufacturer remains at risk of receiving penalties and damaging their customer relationships if code inspections on delivery result in products being returned.
“That’s why the 4Sight system is such an important breakthrough, because it offers a high-performance, dependable solution that’s easy to set up and use.”
