SETT OCH ANORDNING FOR KODNING AV ARBETSSTYCKEBERARE I TILLVERKNINGSANLEGGNINGAR

摘要

Workpiece carriers (4) are fed to successive work stations (2) along conveyor tracks (13) at which stations (2) work operations are performed on individual parts (5) on the carrier (4) and in which a defect signal is allocated when appropriate. After a work operation has been performed a coding member (22) is left in a normal switching position corresponding to a defect coding or displaced into a switching position corresponding to an accept coding if the work operations performed were satisfactory. In a coding device displaceable coding elements (22) are supported by a workpiece carrier (4) and traverse a detector device (10) at the work processing station (2) and a switching element (10) for displacing the coding element (22) from a reject coding switch position to an accept coding switch position. An accept coding is consequently secured only by a deliberate action when satisfactory work processing has been completed and thus subsequent processing of defective parts is avoided simply and with great reliability.
