CHECKING TILES WITH RELIABILITY
A tile manufacturer has find a solution in inspecting the tile quaility. After having been moulded and dried, the tiles need to be fired. They arrive haphazardly along a conveyer belt to be positioned precisely by robots on individual supports on another belt leading to the oven. The robots need to pick and place the tiles on the next conveyor belt without any breakage or false rejects. Even though these tiles are of similar shape, they are different colours and textures and are likely to have certain anomalies which are not necessarily a cause for rejection.

Inpsect the size and color of tile
The challenge at hand regrouped many of the classic difficulties of machine vision and many of those consulted were not capable of handling the task in real time or of taking on the risks inherent in such a project - with the exception of one. They found a new solution: installing a vision system positioned above the line to inspect the colored face of the tiles. The system in place is made up of 2 Fanuc robots and one vision system. Vision system is including a robust camera meeting IP67 standards. Armed with the powerful localisation software, this vision system is capable of confronting the most difficult applications.
Vision software also ensures that the exact position of each tile is captured and recorded. These details are communicated via Ethernet to the robots who use this information to find each tile, pick it up and place it on the next conveyer belt.
Vision system is also capable of "remembering" 80 different models which means there is no need for additional programming or production interruption for the different models passing through the conveyer belts.
