1. Device for automatic stacking of packages on a support in a predetermined spatial arrangement for formation of a stack in which layers of the stack comprise a plurality of packages and the stack includes packages of varying dimensions, said device comprising: at least one supply conveyor which provides the separated packages in a predetermined succession; a lifting and lowering unit for lifting and lowering a support disposed in a stacking site in a vertical Y direction; and a displacement device which adjoins an output end of the supply conveyor and which receives packages from the supply conveyor and transports the packages to predetermined positions in the stack in which each predetermined position in a layer for a plurality of packages comprises a different position with respect to an X and Z direction, with the X direction and Z direction being orthogonal with respect to each other and to the vertical Y direction, and wherein packages of varying dimensions within rows of a layer are accommodated by the displacement device by separately transporting such packages to the corresponding predetermined position for the packages; wherein the displacement device comprises: wherein the at least one pushing plate is formed as a flat strip-like plate, formed to be able to move horizontally and along the side of the stacking site and transverse thereto, in order to receive the packages as the packages are being pushed by the pusher off the positioning conveyor at the X direction position and to lay the packages in the Z direction on the support or in the stack in the predetermined position for each package; wherein the pusher is formed as an arrangement of a plurality of individual pushers disposed horizontally and along the side of the stacking site that push the packages off the positioning conveyor in the direction of the stack, wherein the individual pushers can each move independently of the at least one pushing plate in the Z direction in order to retain the package when the pushing plate is being withdrawn.
