ABSTRACT:
In a workpiece transfer apparatus for a plurality of serially arranged machine tools, a horizontally extending transfer bar which forms a part of a parallel motion mechanism is provided alongside work tables of the machine tools and is vertically movable. A plurality of linear motion members is mounted on said transfer bar at the same interval as the machine tools and is connected to be bodily movable along the transfer bar. Each of the linear motion members carries a plurality of arm members each pivotable about a vertical axis for horizontal swing motion. A transfer jig for supporting a workpiece thereon is secured to each of the arm members. A feed cylinder device is provided to move the linear motion members along the transfer bar so as to transfer each workpiece from a position facing one machine tool to another position facing another machine tool successive thereto. A loading cylinder device is provided to horizontally swing all or a corresponding one of the arm members so as to load workpieces onto the work tables and unload the same therefrom. Further, an elevation cylinder device is provided to vertically move the transfer bar so as to seat the workpieces on the work tables and lift up the same therefrom.
