ABSTRACT:
A sheet workpiece manipulating apparatus for delivering, supporting, and removing large sheet workpieces to a sheet bending press includes a plurality of rotationally and linearly translatable support arms. A gripping device is disposed on each free end of each support arm. The sheet workpiece is captured and rigidly restrained by the paired gripping devices, such as opposing suction cups operationally connected to a vacuum source, which are detachably attached to the support arms in a magnetically cooperating arrangement. Large gripping forces are developed by the gripping devices, which are separately replacable with alternate gripping devices sized to accommodate workpieces of different sizes, shapes, and materials, as well as a particular manipulation procedure. Perforated as well as imperforated sheets may be manipulated by the apparatus due to the paired, opposing relationships of the suction cups.
