ABSTRACT:
Apparatus for driving an automatic workpiece conveyor in a press train which includes a plurality of linkage members articulated to one another to drivingly interconnect a drive element of a press with a workpiece conveyor. The linkage members are interconnected and configured so as to assure movement of the workpiece conveyor between two end positions, with a predetermined stopping interval at the end position, with a continuously moving press drive element. These linkage members include a coupling point interconnecting two of the members which is constrained to move in a predetermined path including two arcuate sections spaced from one another and having the same radius of curvature, which arcuate sections correspond to the end positions of the conveyor. A secondary linkage system is provided for operating a turning device for turning the workpieces when in the end positions. This secondary system includes a two-arm lever having an adjusting motor for threadably moving two parts with respect to one another to effect turning operations. This two-armed lever is pivotally mounted at a rocker arm of the driving linkage for the conveyor.
