1. A tray-handling station for manually unloading piece goods by an order-picking person from a tray onto a pallet in a packing station, wherein the tray-handling station is coupled to the packing station, the tray-handling station comprising: a tray-conveyor system comprising a handling position for buffering at least one tray, which is to be handled and carries the piece goods;a working area including, at least partially, the handling position, and the packing station; anda sliding-surface unit having a substantially horizontal surface that is arranged adjacent to the tray-conveyor system, and adjacent to the packing station;wherein the to-be-handled tray has a top surface for supporting at least one of the piece goods during the unloading of the at least one piece good form the to-be-handled tray located at the handling position, the top surface of the to-be-handled tray being no lower than the sliding surface of the sliding surface unit; andwherein the working area is dimensioned so that, during unloading of the at least one piece good from the to-be-handled tray located at the handling position, the order-picking person moves the to-be-removed piece good from the to-be-handled tray over the sliding surface to a discharging area, which is located within the working area and which, at least partially, overlaps the packing station, such that, during the unloading, the order-picking person moves the piece good from the to-be-handled tray to the discharging area by pulling or pushing only, and only by moving his/her upper body without lifting. 2. The tray-handling station of claim 1, further comprising a tilting device configured to tilt the to-be-handled tray, or the to-be-removed piece good, relative to a substantially horizontally orientated main-conveying plane, which is defined by the tray conveyor system, so that the order-picking person pushes and pulls the to-be-removed piece good over the sliding surface of the sliding-surface unit in a substantially stepless manner from the to-be-handled tray to the discharging area. 3. The tray-handling station of claim 2, wherein the tilting device comprises a tilting-forward device and a tilting-back device, which are integrated into the tray-conveyor system so that they are arranged upstream and downstream relative to the handling position. 4. The tray-handling station of claim 3, wherein a bottom of the to-be-handled tray is tilted relative to the main-conveying plane so that the piece goods slip towards the order-picking person. 5. The tray-handling station of claim 4, wherein the tilting device further comprises a ramp, which is configured to be lifted and lowered, to reach through the to-be-handled tray and to be tilted oppositely to the bottom of the tray. 6. The tray-handling device of claim 2, wherein the tilting device comprises an array of rollers, which defines a transport plane and which reaches through a bottom of the to-be-handled tray such that the transport plane is tilted relative to the main-conveying plane. 7. The tray-handling station of claim 1, wherein the sliding-surface unit is flush-coupled to the tray-conveyor system and to the packing station. 8. The tray-handling system of claim 1, wherein the sliding-surface unit includes first and second legs forming the sliding surface, the first leg extending in a longitudinal direction along and adjacent to the tray-conveyor system, the second leg extending transversely to the first leg and adjacent the packing station, and the legs defining therebetween a region in which the order-picking person can be positioned. 9. The tray-handling device of claim 1, wherein the sliding-surface unit comprises a skirt, which is substantially orientated vertically and ends with an edge of the sliding surface in a flush manner, the edge facing the order-picking person. 10. The tray-handling station of claim 1, wherein the sliding surface decreases from the tray-conveyor system towards the packing station. 11. The tray-handling station of claim 1, wherein the tray-conveyor system is configured to be moved in a clocked manner, at least within the working area, and wherein the handling position is defined by a section of the tray-conveyor system, where the to-be-handled tray rests during removal or delivery of one of the piece goods. 12. The tray-handling station of claim 1, wherein each of the trays has a circumferential rim so that the piece goods cannot slip-off laterally from a transport area of the tray. 13. The tray-handling station of claim 1, wherein each of the trays is adapted to receive one pallet layer, or pallet row, of the piece goods. 14. The tray-handling station of claim 8, wherein the first and second legs of the sliding surface unit enclose an angle of about 10 to 170 degree. 15. A storage and order-picking system having a tray warehouse and a tray-handling station for manually unloading piece goods by an order-picking person from a tray onto a pallet in a packing station, the tray-handling station comprising: a tray-conveyor system comprising a handling position for buffering at least one tray, which is to be handled and carries the piece goods;a working area including, at least partially, the handling position, and the packing station; anda sliding-surface unit having a substantially horizontal sliding surface that is arranged adjacent to the tray-conveyor system, and adjacent to the packing station;wherein the to-be-handled tray has a top surface for supporting at least one of the piece goods during the unloading of the at least one piece good from the to-be-handled tray located at the handling position, the top surface of the to-be-handled tray being no lower than the sliding surface of the sliding surface unit; andwherein the working area is dimensioned so that, during unloading of the at least one piece good from the to-be-handled tray located at the handling position, the order-picking person moves, the to-be-removed piece good from the to-be-handled tray over the sliding surface to a discharging area, which is located within the working area and which, at least partially, overlaps the packing station, such that, during the unloading, the order-picking person moves the piece good from the to-be-handled tray to the discharging area by pulling or pushing one, and only by moving his/her upper body without lifting. 16. A method for loading or unloading piece goods in a storage and order-picking system having a tray-handling station for manually unloading the piece goods by an order-picking person from a tray onto a pallet in a packing station, wherein the tray-handling station is coupled to the packing station, the tray-handling station comprising: a tray-conveyor system comprising a handling position for buffering at least one tray, which is to be handled and carries the piece goods; a working area including, at least partially, the handling position, and the packing station; and a sliding-surface unit having a substantially horizontal sliding surface that is arranged adjacent to the tray-conveyor system, and adjacent to the packing station; wherein the to-be-handled tray has a top surface for supporting at least one of the piece goods during the unloading of the at least one piece good from the to-be-handled tray located at the handling position, the top surface of the to-be-handled tray being no lower than the sliding surface of the sliding surface unit; and wherein the working area is dimensioned so that, during unloading of the at least one piece good from the to-be-handled tray located at the handling position, the order-picking person moves the to-be-removed piece good from the to-be-handled tray over the sliding surface to a discharging area, which is located within the working area and which, at least partially, overlaps the packing station, such that, during the unloading, the order-picking person moves the piece good from the to-be-handled tray to the discharging area by pulling or pushing only, and only by moving his/her upper body without lifting, the method comprising the steps of: conveying the to-be-handled tray to the handling position of the tray-conveyor system;providing the to-be-handled piece good within the working area of the order-picking person so that the order-picking person can transfer the piece good only by moving his/her upper body without lifting; andpulling or pushing the piece good from the to-be-handled tray over the sliding surface of the sliding-surface unit to the discharging area located within the working area.
