Inspecting for Missing Chocolates on a Packaging Line

In the packaging process, it's important that the correct number of chocolates are present in every box in order to meet quality inspections. While this inspection can be done using a traditional vision system, it can also be accomplished with traditional photoelectrics.


Banner sensors are positioned above a conveyor inspecting each passing box for missing chocolates. When a passing box breaks the trigger beam created by a pair of Q12 opposed-mode sensors, an array of QS18AF sensors mounted above the box inspect each location for missing chocolates.

When a box containing the wrong amount of chocolates is detected, an output signal is relayed to a main controller at the packaging line warning of the failed condition.
