DETAILED DESCRIPTION

[0035] FIG. 1 is an exploded view of a system 10 for transporting goods. System 10 includes a transport container 20 for holding goods, a driverless transport vehicle 30 for transporting transport container 20, and a transfer station 40, on which transport container 20 may be positioned. System 10 is used for delivering goods to a private recipient. To that end, transfer station 40 is situated, for example, in front of a residential building, in which the private recipient lives.

[0036] Transfer station 40 is formed approximately in the shape of a U-profile and has a first side 43, a second side 44, and a third side 45, which connects first side 43 and second side 44. Third side 45 is approximately planar and extends perpendicularly to a vertical direction Z. Sides 43, 44 are each approximately planar and extend perpendicularly to a transverse direction Y.

[0037] In this context, vertical direction Z extends perpendicularly to the ground. Transverse direction Y extends perpendicularly to vertical direction Z. A longitudinal direction X extends perpendicularly to transverse direction Y and perpendicularly to vertical direction Z. Therefore, longitudinal direction X and transverse direction Y extend horizontally and perpendicularly to the ground.

[0038] Third side 45 is anchored securely in the ground. Consequently, transfer station 40 is protected against theft. First side 43 and second side 44 are set apart from each other in transverse direction Y. Therefore, a through-region, which extends in longitudinal direction X, is formed between sides 43, 44. A dimension of the through-region in transverse direction Y is selected such that it is possible for driverless transport vehicle 30 to pull into the through-region. In this context, it is possible for driverless transport vehicle 30 to pull into the through-region and to pull out of the through-region from both sides.

[0039] A support bar 42 is attached to both first side 43 and second side 44. For example, support bars 42 are positioned in a region of sides 43, 44 opposite to third side 45 and extend into the through-region. Support bars 42 form a second locking unit of transfer station 40.

[0040] Driverless transport vehicle 30 includes a chassis 33, as well as a plurality of wheels 34. The driverless transport vehicle includes six wheels 34. At least a portion of wheels 34 may be driven by a motor. Driverless transport vehicle 30 also includes an electrical energy store for powering the motor. At least a portion of wheels 34 are steerable. Alternatively, driverless transport vehicle 30 has differential steering. For example, wheels 34 are not steerable, but driverless transport vehicle 30 may be steered, using different speeds of the wheels 34 on the two sides, in a manner similar to a chain drive of a tank or an excavator. For example, driverless transport vehicle 30 moves in longitudinal direction X.

[0041] Driverless transport vehicle 30 further includes a lifting unit, with the aid of which a transport container 20 situated on transport vehicle 30 may be moved in the vertical direction Z relative to chassis 33. To that end, the lifting unit includes, for example, a lifting platform.

[0042] Driverless transport vehicle 30 also includes two grooves 32, which are set apart from each other. For example, grooves 32 are set apart from each other in transverse direction Y. In this context, grooves 32 form a first locking unit of driverless transport vehicle 30.

[0043] Transport container 20 includes a basic housing 23 and a cover 24. For example, basic housing 23 is closed with the aid of cover 24. Basic housing 23 and cover 24 surround a hollow space 25, into which goods to be transported may be placed. Transport container 20 also includes a locking module, with the aid of which cover 24 may be locked to basic housing 23. When cover 24 is locked to basic housing 23, goods situated in hollow space 25 are protected from unauthorized access.

[0044] Transport container 20 also includes a locking device. The locking device includes a plurality of movable latches 22, which interact with grooves 32 of driverless transport vehicle 30, as well as with support bars 42 of transfer station 40.

[0045] The locking device of transport container 20 may be locked to the first locking unit of driverless transport vehicle 30. In order to lock, latches 22 of the locking device engage with grooves 32, which form the first locking unit of driverless transport vehicle 30.

[0046] The locking device of transport container 20 may also be locked to the second locking unit of transfer station 40. In order to lock, latches 22 of the locking device engage with support bars 42, which form the second locking unit of transfer station 40.

[0047] In the following, the method for transporting goods with the aid of the system 10 for transporting goods is explained in light of an example. The goods, which are to be transported to transfer station 40, are initially placed into hollow space 25 of transport container 20. Cover 23 of transport container 20 is subsequently closed and locked to basic housing 23 by the locking module.

[0048] The locking device of transport container 20 is locked to the first locking unit of driverless transport vehicle 30. Transport container 20 is then transported by driverless transport vehicle 30 to transfer station 40.

[0049] FIG. 2 shows the system 10 illustrated in FIG. 1 during the transport of transport container 20 on driverless transport vehicle 30 to transfer station 40. Driverless transport vehicle 30 moves, for example, towards transfer station 40 in longitudinal direction X.

[0050] During the transport, the locking device of transport container 20 is locked to the first locking unit of driverless transport vehicle 30. For example, the latches 22 of the locking device engage with grooves 32, which form the first locking unit of driverless transport vehicle 30. For example, transport container 20 is situated above driverless transport vehicle 30 in vertical direction Z.

[0051] FIG. 3 shows the system illustrated in FIG. 1, including a raised transport container 20, in the immediate vicinity of transfer station 40. The locking device of transport container is unlocked from the first locking unit of driverless transport vehicle 30, and transport container 20 is raised by the lifting unit of driverless transport vehicle 30, e.g., moved upwards in vertical direction Z.

[0052] Driverless transport vehicle 30 includes a control unit, in order to unlock the locking device from the first locking unit. With the aid of the control unit, the locking device may also be unlocked from the second locking unit.

[0053] Subsequently, driverless transport vehicle 30 moves further in longitudinal direction X and travels into transfer station 40.

[0054] FIG. 4 shows the system 10 illustrated in FIG. 1, including a driverless transport vehicle 30 situated in transfer station 40. For example, transport container 20 is positioned above transfer station 40 in vertical direction Z.

[0055] Transport container 20 is subsequently lowered by the lifting unit of driverless transport vehicle 30, e.g., moved downwards in vertical direction Z, and set down on transfer station 40. FIG. 5 shows the system 10 illustrated in FIG. 1, including a transport container 20 set down on transfer station 40. For example, the locking device of transport container 20 is also locked to the second locking unit of transfer station 40.

[0056] Driverless transport vehicle 30 moves away from transfer station 40 and from transport container 20. FIG. 6 shows the system 10 illustrated FIG. 1, including a driverless transport vehicle 30 moving away. The locking device of transport container 20 is locked to the second locking unit of transfer station 40. For example, latches 22 of the locking device engage with support bars 42, which form the second locking unit of transfer station 40.

[0057] FIG. 7 shows the system 10 illustrated in FIG. 1, including an open transport container 20. The recipient of the goods, e.g., a person authorized to open transport container 20, initially ends the locking of cover 24 to basic housing 23 caused by the locking module. Cover 24 is opened. The recipient removes the goods from hollow space 25 of transport container 20.

[0058] As an option, goods, which are to be transported away from transfer station 40, are placed into hollow space 25 of transport container 20. Cover 23 of transport container 20 is subsequently closed and locked to basic housing 24 by the locking module. For example, the locking device of transport container 20 is still locked to the second locking unit of transfer station 40.

[0059] Driverless transport vehicle 30 pulls into transfer station 40. With the aid of the control unit of driverless transport vehicle 30, the locking device of transport container 20 is unlocked from the second locking unit of transfer station 40. With the aid of the lifting unit of driverless transport vehicle 30, transport container 20 is raised, e.g., moved upwards in vertical direction Z.

[0060] Driverless transport vehicle 30 moves with transport container out of transfer station 40, and transport container 20 is lowered by the lifting unit of driverless transport vehicle 30, e.g., moved downwards in vertical direction Z. The locking device of transport container 20 is locked to the first locking unit of driverless transport vehicle 30. Transport container 20 is subsequently transported away from transfer station 40 by driverless transport vehicle 30.
