APEX Automation and Robotics created a turnkey 3D vision system for a leading food manufacturer to automatically inspect the lids on sauce jars and bottles.
A popped lid in a food jar indicates that the seal is broken and vacuum inside the jar has been breached, resulting in spoilage of the product. It is critical in any food manufacturing facility to ensure that these jars are detected before they leave production and make their way to the supermarket shelf.
Manual inspection by an operator is not a reliable technique to check the lid on every jar since it is not always easy to distinguish between a popped lid and a good one especially when the production rate is high.
APEX Automation and Robotics used 3D vision technology to design a system that automatically inspected the lids on sauce jars and bottles. As each jar moves on a conveyor under the 3D camera, the profile of the lid is scanned, and algorithms are used to measure and detect popped lids.
Key features of the 3D vision inspection system:
- Can handle a wide range of jars and bottles of different heights without any mechanical adjustments
- Using a laser line ensures a robust solution eliminating sensitivity to ambient light or lid colour
- Inspects every single jar at a rate exceeding 100 jars/min
- Faulty jars are tracked down and rejected off the line
