Abstract
Methods for welding motor vehicle body component subassemblies at a weld stations are disclosed. First and second pallets may be arranged for reciprocal movement between a load/unload station and the weld station and the pallets are alternately moved from a load/unload station to the weld station while the other pallet is moved from the weld station to a load/unload station. Each pallet may have a plurality of substations for receipt of component subassemblies and, while each pallet is at the load/unload station, the component subassembly at each substation is moved to the next successive substation and a further component is added to the moved component.
Claims12
A method of welding motor vehicle components at a weld station comprising:
- providing a pallet having a plurality of successive substations for receipt of component subassemblies;
- reciprocally moving the pallet back and forth between a load/unload station and the weld station;
- while the pallet is at the load/unload station, moving the component subassembly at each substation to the next successive substation and adding a further component to each moved component subassembly;
- and
- while the pallet is at the weld station, welding each component subassembly at each substation of the pallet.
A method of welding motor vehicle components at a weld station comprising:
- providing first and second pallets reciprocally movable between a load/unload station and the weld station and each having a plurality of successive substations for receipt of component subassemblies;
- alternately moving each pallet from its load/unload station to the weld station while moving the other pallet from the weld station to its load/unload station;
- and
- while each pallet is at its load/unload station, moving the subassembly of components at each substation to the next successive substation and adding a further component to each moved subassembly.
A method of welding motor vehicle components at a weld station comprising:
- providing a pallet having a plurality of successive substations for receipt of component subassemblies;
- reciprocally moving the pallet back and forth between a load/unload station and the weld station;
- while the pallet is at the load/unload station, moving the component subassembly at each substation to the next successive substation and adding a further component to each moved component subassembly;
- while the pallet is at the weld station, welding each component subassembly at each substation of the pallet;
- and
- repeating until a final welded subassembly is presented at the final substation with the pallet positioned at the load/unload station, whereafter the final welded subassembly is removed from the pallet for use in further motor vehicle assembly processes.
A method of welding motor vehicle components at a weld station comprising:
- providing a pallet having a plurality of successive first, second and third substations for receipt of component subassemblies;
- reciprocally moving the pallet back and forth between a load/unload station and the weld station;
- while the pallet is at the load/unload station:
- a subassembly consisting of components A/B/C/D is removed from the third substation;
- a subassembly consisting of components A/B/C is moved from the second substation to the third substation;
- a new component D is added to the subassembly A/B/C positioned at the third substation;
- a subassembly consisting of components A/B is moved from the first substation to the second substation;
- a new component C is added to the subassembly A/B positioned at the second substation;
- and
- new components A and B are loaded onto the first substation;
- and
- while the pallet is at the weld station, welding each component subassembly at each substation of the pallet.
