Three AGVs with magnetic tape navigation transport glass from logistics zone to the production line. As soon as the AGV receives a signal that the forklift driver has inserted a cage with glasses into one of the four cubicles, the AGV will drive up to this cage and use the lifting mechanism to lift it and transport it to the production line. Here it places the cage fitted with wheels on the floor and slowly slides it into the production line. Empty cages are loaded from the other side of the line in the same way back to logistics zone to a free position in the cubicle, where the forklift driver is instructed by light signal, where to put the cages filled with glass and from where to load by same way empty cages back to the semi-trailer.
