In a system for coding a pallet on which a plurality of parts are assembled to form a workpiece in an assembly line, a drive for moving the pallet in a conveying path along the assembly line to successive work stations where the parts are processed or assembled, a plurality of signal carriers on the pallet for generating a signal indicating a defect in the workpiece on the pallet in a respective work station, signal read-out and encoding devices arranged along the conveying path for receiving the generated signals and emitting corresponding control signals, the drive being responsive to the emitted control signals whereby the defective workpiece may be excluded from work in work stations subsequent thereto, the signal carriers being arranged on the pallet in an array in adjacent rows extending in the conveying direction and spaced from each other in this direction, and respective signal carriers in rows spaced from each other in this direction and extending perpendicularly to the adjacent rows for enabling the signals in the perpendicular rows to be sensed simultaneously, one of the adjacent rows providing a respective signal carrier in each perpendicular row, and the signal read-out and encoding device having sensors associated with the signals carriers in the adjacent rows. |
