ABSTRACT:
A transfer arrangement includes a transfer unit constructed as a three-axle transfer unit. For two parallel, spaced gripper rails which are to be moved synchronously, stationarily disposed driving units are provided for the respective transport direction, the transverse direction and the stroke direction. The transverse driving unit acts by way of coupling devices upon the gripper rails to establish a driving connection between the transverse driving unit and the gripper rails only when these must be laterally adjusted. Otherwise, the transverse driving unit is separated from the gripper rails. Thereby, the masses, which are to be moved up and down with the gripper rails and the resulting acceleration forces are considerably reduced and shortened timing periods are permitted. The transverse driving unit 40 can be arranged below a plane defined by the gripper rails. For exchanging workpieces disposed on sliding tables, the gripper rails can move into a very lifted position without also having to lift the transverse driving unit, which otherwise would require a corresponding free space in the transfer arrangement.
