METHOD FOR AT-FACTORY PRE-ASSEMBLY OF A TRANSPORTATION SYSTEM, AND ASSEMBLY PLANT FOR MANUFACTURING A TRANSPORTATION SYSTEM

摘要

Assembly plant (20) for at-factory pre-assembly of transportation systems (10.1 - 10.17) with several assembly stations (20.1 - 20.13). In every assembly station (20.1 - 20.13), part of a respective transportation system (10.1 - 10.17) is pre-assembled. The assembly stations (20.1 - 20.13) are arranged in the sequence of the assembly steps that are to be executed and have assembly-step-specific tool devices as well as devices for making ready an inventory of assembly--step-specific assembly components. A production control system (30) is provided for the purpose of controlling, or triggering, execution of the assembly steps and individual movement of the transportation systems (10.1 - 10.17) from one assembly station (20.1 - 20.13) to a next following assembly station (20.1 - 20.13) in the assembly plant (20) in such manner that each transportation system (10.1 - 10.17) is alternately moved and subjected to assembly steps. The assembly steps proceed in a rhythm (.tau.) that is defined by a pre-specified fixed standard assembly-time window T.
