Patent ID: 8424359

Claim:
Production device for the bending deformation of boards or workpieces, comprising a bending press, a fixed table beam and a press beam adjustable by means of a drive arrangement relative to the table beam in guides on a machine frame and comprising bending tools arranged on facing end faces of the table beam and the press beam and a manipulator which can be driven in a track parallel to a longitudinal extension of the table and bending beams for the transfer of a workpiece between a feeding or stacking device for the boards or workpieces and a shaping area between the bending tools and with at least one control and monitoring device and the manipulator, a bending arm arrangement with three arms pivotable via pivot bearing arrangements about pivot axes aligned parallel to the running track and on a distal end of the bending arm arrangement a rotational unit is arranged, with a rotational axis running perpendicular to the pivot axes and the rotational unit is fitted with a gripping device and the latter comprises at least one detecting device connected by communication to the control and monitoring device, characterised in that the detecting device with several measuring elements arranged in a measurement plane forms a measuring device for a physical value causing a change in state of an arm of the bending arm arrangement upon loading and the measurement plane runs between the distal end of the bending arm arrangement and the rotational unit.
