Claim:
A workpiece gripper arrangement for the automatization of presses, particularly for large component stage presses, comprising: a transfer arrangement ( 4 ) including a girder ( 6 ) moveably supported by a drive arrangement ( 16 ) for operating the transfer arrangement, gripper means ( 7 ) supported by the girder ( 6 ) for the controlled gripping and releasing the components, a coupling arrangement ( 31 ) including two coupling parts ( 36 , 37 ) of which one is connected with the girder ( 6 ) and the other with the gripper means ( 7 ), the coupling part ( 37 ) associated with the gripper means ( 7 ) includes an arresting structure ( 47 , 49 ) by way of which the gripper means ( 7 ) is engaged on a support frame ( 48 ), the arresting structure ( 47 , 49 ) is engageable by a linear relative movement between the gripper means ( 7 ) and the support frame ( 48 ) in a direction transverse to the longitudinal length of the girder ( 6 ), the drive arrangement ( 16 ) includes adjusting drive ( 17 ) in operative arrangement with the gripper means ( 7 ) for longitudinal movement of the gripper means ( 7 ) along the girder ( 6 ), the coupling arrangement ( 31 ) comprising a mechanical locking structure ( 40 ) including an operating pin section ( 45 ) which is operable in a direction transverse to the longitudinal length of the girder ( 6 ) by a linear relative movement of the coupling arrangement ( 31 ) with respect to a stop member ( 51 ) which transfers the locking structure ( 40 ) to a release position when activated by the stop member ( 51 ) operatively engaging pin section ( 45 ).
