1. Device for automatically stacking packages on a support in a predetermined spatial arrangement to form a stack, comprising: at least one feeding conveyor which provides singulated packages in a predetermined sequence; a lifting and lowering unit for lifting and lowering a support, which is arranged in a stacking location, in the Y-direction; and a displacement device which adjoins an output end of the feeding conveyor and receives packages from the feeding conveyor and transports the packages to predetermined positions in the stack; wherein the displacement device comprises: wherein the positioning conveyor defines a travel path and is designed as a transfer cart and the transfer cart includes a transport surface upon which packages are disposed to position the packages in the X-direction, and wherein the at least one sliding plate is designed as a flat, strip plate which is movable horizontally and along the side of the stacking location and transversely thereto, in order to receive the packages from the positioning conveyor at the X-direction position when the packages are pushed by the pusher and to place the packages on the support or in the stack in the Z-direction, wherein a front of the at least one sliding plate is initially disposed on a side of the positioning conveyor opposite the stacking location, and wherein the front of the at least one sliding plate is then extended across the travel path of the positioning conveyor underneath the transport surface with a portion of the at least one sliding plate extending from underneath the transport surface beyond a perimeter of the transport surface to receive packages from the transfer cart when the packages are pushed off the transport surface by the pusher and onto the portion of the at least one sliding plate extending beyond the perimeter of the transport surface.
