1. An assembly line comprising:
- a plurality of work stations positioned along a direction of conveyance of the assembly line, and each work station having a work area;
a drive conveyor for conveying parts to be assembled from one work station to the next in a successive manner along the direction of conveyance;
each work station including a production part tray for holding the parts being assembled within the work area of the work station; and
one of the work stations also including a pilot part tray for handling a combination of pilot parts to be assembled in preparation for future production, the one work station also including a maintenance station located outside of the work area of the one work station, an indexer for indexing the production and pilot part trays of the one work station in a direction transverse to the direction of conveyance so as to permit one of the these part trays to be used in the assembly of its associated combination of parts in the work area, and the indexer including a detachable coupling for attaching to the pilot part tray for the indexing and being detachable therefrom so the pilot part tray can be moved to the maintenance station externally of the work area thereof in preparation for the future production.

Abstract
An assembly line (14) having particular utility for use in assembling sheet metal parts includes a work station (18) having one or more production part trays (32, 34), a pilot part tray (36) and an indexer (38) that indexes these part trays in a transverse direction to a direction of conveyance (C) of the assembly line to permit one of the two production part trays (32, 34) to be used for production or the pilot part tray (36) to be used for a future pilot test. Detachable couplings (56) allow the production and pilot part trays to be moved to a maintenance station (42, 44) that is outside of the assembly line work area (25).

5. A system including an assembly line for securing sheet metal parts to each other, comprising:
-
a plurality of work stations positioned along a direction of conveyance of the assembly line;
a drive conveyor for conveying sheet metal parts to be assembled from one work station to the next in a successive manner along the direction of conveyance;
each work station also including a robot for securing sheet metal parts to each other;
each work station including a part tray for holding the parts being assembled; and
one of the work stations including first and second production part trays for selectively handling two different combinations of production parts to be assembled, said one work station also including a pilot part tray for handling another combination of pilot parts to be assembled in preparation for future production, the one work station including a maintenance station, and an indexer including detachable couplings for selectively attaching to the production and pilot part trays for indexing thereof in a direction transverse to the direction of conveyance so as to permit one of the three part trays to be used in the assembly of its associated combination of parts, and the detachable couplings selectively being detachable from either of the production part trays and the pilot part tray to permit movement thereof to the maintenance station for work in connection with the future production.
