Abstract

A transferring apparatus for a transfer press machine which includes a plurality of working stations disposed in a work-transferring direction and provided with lower dies and upper dies cooperating to press workpieces, so that the workpieces are sequentially transferred between the working stations. A plurality of sets of pairs of left and right carriages are associated with one of the working stations. The spacings between adjacent twos of the sets of the carriages are adjusted in said transferring direction during operation. At least one cross bar is mounted to extend between the left and right carriages of each set and has suction cups mounted on an intermediate portion thereof for holding the workpiece. The cross bar is cyclically movable in the transferring direction and in a vertical direction. A pair of left and right guide bars vertically movably are mounted to extend along opposite sides of the working stations to provide the cyclic motion of the cross bar. A pair of left and right feed plates are supported on the guide bars for movement in the transferring direction. The structure for adjusting supports the carriages on said feed plates so that their positions can be adjusted. Alternatively, feed plates are supported for movement in the transferring direction on a pair of left and right guide bars which are fixedly mounted to extend along opposite sides of the working stations to provide the cyclic motion of the cross bar. The carriages are supported on the feed plates respectively so that their positions can be adjusted with the cross bar being vertically movably supported on said carriages.
