<p>Work is performed on workpieces, e.g., coating circuit boards, of different types in random order in assembly line fashion on a rotary table of an apparatus under programmed control. The table is rotated stepwise to move successive sections thereof from a load-unload station at which the respective workpieces are loaded and unloaded in random order, to a sensing station at which the type and orientation of the workpiece is sensed, next to a work station at which work is performed on the workpiece in dependence upon its type and orientation previously sensed at the sensing station, and in turn back to the load-unload station to complete a cycle. The workpiece is either changed in orientation on the table section for a repeat cycle to perform further work thereon or is replaced by another workpiece in random order.</p> |
