Unloading and stacking floor tile slabs onto a wooden pallet has been automated using a vision-guided robot.
In operation, the automated vision system captures an image of each slab and analyses the image to determine its size, colour and shade. It then compares this with the values from the previous slab. By doing so, the system can determine if a product change has taken place on the production line.
After the vision inspection has taken place, slabs are transferred to a second conveyor. At this point, an ABB robot picks the slabs from the conveyor and stacks them onto pallets. Once the vision system detects a product change, it instructs the robot to automatically switch the stacking to a new pallet.
