Abstract:
1. A manufacturing system for workpieces in the form of sheet metal bars shaped by folding, comprising: a folding press having two press beams adjustable in relation to each other and provided with folding dies; an automated manipulating device comprising a rotating unit and a gripping device and displaceable on a guiding arrangement in the direction of a longitudinal axis of the press beams; a positioning device for positioning workpieces between the folding dies; and a controlling and monitoring system, wherein the manipulating device comprises three hinged arms connected via swiveling devices to form a hinged-arm arrangement, wherein an end of a first hinged arm is pivot-mounted by a swiveling device mounted on a linearly displaceable chassis of the guiding arrangement such that the first hinged arm is pivotable about a swivel axle extending parallel to a guiding track of the guiding arrangement; a second and a third swivel axle of the swiveling devices supporting the hinged arms are arranged extending parallel to the swivel axle of the swiveling device on the chassis; the rotating unit, having a rotation axle extending perpendicularly to the swiveling axles, is arranged in another end area of the hinged-arm arrangement; an image acquisition system is arranged in the end area of the hinged-arm arrangement, said acquisition system comprising at least one image-acquiring means and at least one illumination system and one laser for identifying and recognizing the workpieces; and the positioning device is formed by a stop device with at least two stop fingers adjustably arranged on a backside of the folding dies facing away from the manipulating device in a plane disposed parallel to the folding plane and in the vertical direction in relation to said plane, the stop fingers having finger carriers and finger inserts adjustable in said finger carriers to a spacing in relation to sensors measuring said spacing.
