Abstract:
1. An assembly plant for use in assembling mechanical parts on motor-vehicle bodies, comprising: an endless pallet conveyor line having: the plurality of vehicle mechanical parts supporting pallets each movable in said closed loop conveyor line wherein each pallet proceeds along said first lower line from the starting end to the final end in a first direction, said pallets being then transferred from the final end of said first lower line section to the starting end of said second upper line section at the first transfer station, said pallets then proceeding along said second upper line section in a second direction opposite the first direction until reaching the final end of said second upper line section, where they are moved again to the starting end of the first lower line section by the second transfer station; means provided along said first lower line section for loading the mechanical parts of motor-vehicles on said pallets while said pallets are proceeding along said first lower line section, each pallet adapted to receive the mechanical parts of a respective motor-vehicle; means for loading a respective motor-vehicle body on each pallet at a loading station located in proximity of said second upper line starting end, so that said motor-vehicle body is coupled with the mechanical parts which have been loaded on the pallet along the first lower line section; at least one bolting station positioned along said second upper line wherein said mechanical parts are bolted from below to said motor-vehicle body; a pair of programmable manipulating robots each for bolting said mechanical parts to said motor-vehicle body at said bolting station of said second upper line, said pair of robots being arranged on each opposing side of and transverse to said first lower line section to accommodate the passing of said pallets between the pair of robots while said pallets are proceeding along said first lower line section; and means for unloading the respective body with the connected mechanical parts in proximity of the final end of said second upper line section.
