Complete reliability for baby food packaging

Complete reliability for baby food packaging Supplying packaging for a global baby food manufacturer cannot be taken lightly. Huhtamaki France was faced with potential technical and public relations issues when dealing with a seemingly straightforward challenge - one that could only be completely and safely satisfied using machine vision from Cognex. Each element for the packaging of a baby food container is produced individually by Huhtamaki to be sent back to the client for filling. The transparent lid of each container being produced at very high rates each day has a label affixed declaring the contents and flavour of the food. It is vital that each delivery to the client contains the right label. The company based its solution on Cognex InSight, equipping both lines on the conveyer with a camera and connecting the Huhtamaki interface simply by OPC on one PC. The use of Cognex advanced vision tools in the form of PatMax provided for a simple interface with the product images clearly displayed and played a decisive part in recognising the label and acquiring the image to be assessed. Using PatMax, the programme memorises and recognises an area of text and certain aspects of the label as well as its positioning on the lid. There is no need for any complex parameter configuration which ensures ease of use and long term flexibility. An item that does not correspond correctly to the image acquired is immediately rejected. The capacity of PatMax to acquire a sufficient amount of detailed information ensures not only zero defects but also a negligible rate of false rejects. The simplicity and reliability of the solution permits Huhtamaki to maintain a high level of production without compromising quality to the extent that the company is considering applying the technology to other areas of their production.
