At the end of the manufacturing line of insulating glass units (IGU), TECAUMA’s the robotic cell does the palletizing of finished glasses on trolleys or racks. First, a 6 axis poly-articulated robot, put cork pads on each glass: "smart" cork pad setting, according to the size of the following glass unit on the line. At the end of the line, the glazing is handled by a second robot, equipped with a vacuum gripper. Automatically, the robot turns on itself and unload the glazing on its conditioning apparatus, in a preprogrammed position. The operations are repeated successively until complete palletization of the apparatus. The robot switches automatically to a second apparatus, thus ensuring flow continuity. A security doors system allows the change of apparatus without interruption of the production.
