Abstract
A 'lift and carry' transfer apparatus is provided for transferring or 'indexing' a workpiece between successive work stations in a multi-operation process. The transfer apparatus includes a modular support structure from which a generally elongated shuttle assembly is horizontally supported. A first drive mechanism is provided for generating a predetermined amount of reciprocable rectilinear vertical movement of the shuttle assembly through a predetermined range of motion. The transfer apparatus further includes structure for selectively indexing the workpiece along a horizontal plane relative to the shuttle assembly. In particular, a second drive mechanism is provided for generating rectilinear horizontal motion of the workpiece. A programmable controller is provided for selectively controlling the actuation of the first and second drive mechanisms.
