     TECHNICAL FIELD 
     The present disclosure relates to a transfer station configured to handle cargo and a cargo receptacle sorting method. 
     BACKGROUND 
     Commerce has experienced considerable growth and improvement with respect to processes, technology, reliability and speed. Expectations continue to grow that cargo delivery times can be reduced. As the speed of cargo transportation such as trucks, ships and aircraft is not forecast to improve greatly for the foreseeable future due to increasing congestion, technological limitations and regulations, there is some hope that an improvement in cargo delivery times might be found by optimizing other segments of the logistics chain, such as packaging, sorting, storage and/or drone-based delivery. In particular, it was found that the sorting of various cargo items to different storage facilities and destinations requires heavy investment in large sorting centers that are capital intensive. 
     An object underlying the present disclosure is to provide an efficient way for cargo to be handled.

     Because the sorting of cargo is done directly from a cargo storage unit to another by means of transfer stations, no separate conveyor or sorter-grid based sorting equipment is required. Cargo can remain in cargo storage units, in particular in cargo receptacle carts, from packing of cargo into a cargo receptacle to delivery of the cargo to an ordering recipient, and can thus be handled with maximum care and minimal disturbance. 
     In a variation, the cargo logistics system comprises an electronic tracking system including an electronic circuit, the electronic tracking system being configured to track the cargo receptacle, the cargo storage unit and/or the transfer station, for example based on detecting identification tags and/or optical indicators if provided. 
     The electronic circuit of the electronic tracking system may comprise at least one of the following elements: data memory, a processor, a communications interface for communication with cargo receptacles, cargo storage units and/or transfer stations, preferably a wireless communications interface, a user interface for use by an operator, a network element, a communications network linking one or more of these elements. The electronic circuit of the tracking system may also comprise sensors or detectors for detecting position, size and/or status information of the cargo receptacle, the cargo storage unit and/or the transfer station. A respective sensor or detector may be arranged on a transfer station and/or on a cargo storage unit or at certain fixed positions in a warehouse. In a variation, the electronic tracking system includes any optical indicators and/or tags, in particular electronic tags such as active or passive electronic tags including RFID tags, and/or codes, in particular bar-codes, where provided on a cargo receptacle, cargo storage unit and/or a transfer station, the indicators and/or tags being configured to communicate with the electronic circuit of the tracking system. The electronic tracking system may also include handheld devices for reading the optical indicators and/or tags, such as a handheld bar-code reader. 
     The electronic tracking system of the cargo logistics system may be configured to maintain an inventory and localize cargo receptacles, cargo storage units and/or transfer stations based on RFID, BLE (Bluetooth Low Energy), NFC, mobile tracking technology or other localization technique. Identification of cargo receptacles and/or cargo content thereof, cargo storage units and/or transfer stations may be done based on information transmitted via the mentioned optical indicators and/or tags. The identification may also be done through a specific identification number logic detectable on the respective cargo receptacle, cargo storage unit or transfer station, for example via an identification tag or visual indicator or code. The identification number logic may include information such as the cargo item, size, and capacity of the cargo receptacle cart and it may be printed or hand-written. 
     In a variation, the electronic tracking system is configured to track the shipment status of each cargo receptacle, based on, for example, optical indicators such as differently colored lights. For example, ready for delivery cargo receptacles indicate this status with a green light, cargo receptacles intended for return are indicated with a red light, and cargo receptacles containing second deliveries are indicated with an orange light and cargo receptacles containing new cargo are indicated with a yellow light. The lights may be arranged on the respective cargo receptacle and include LEDs. In addition, or alternatively, the electronic tracking system is configured to track the shipment status of the cargo receptacle via computer screens or handheld devices. 
     In a variation, a computer program is mounted or installed on the electronic circuit for running the electronic tracking system, in particular controlling the cargo storage unit, for example the locking bar or door of a cargo receptacle cart as described below, and/or controlling the transfer station, in particular any component of the transfer station, and/or controlling an optical indicator or active electronic tag of a cargo receptacle, cargo storage unit and/or transfer station where provided. 
     The electronic tracking system is preferably installed in a warehouse, fulfillment center, sorting area, transfer area of a mail-order firm, logistics center and/or depot. 
     In a variation, the cargo logistics system comprises a packing station including an arrangement of at least one packing surface such as a table or system of track pairs for mounting a cargo receptacle, a plurality of cargo receptacles, at least one transfer station, and a plurality of cargo storage units. In a variation, the packing station comprises a lifting device for lifting and lowering the packing surfaces. Preferably, the packing station includes a picking machine, in particular a picking robot, although service personnel may be employed instead. At least one of the cargo storage units preferably carries an empty cargo receptacle. In a variation, the packing station includes at least one transfer station as described in this document, whereby the transfer station may be configured to retrieve a packed cargo receptacle from the packing surface. The picking robot, where provided, may be configured to pick cargo from a cargo storage nearby and place it in the cargo receptacle which, in a variation, the transfer station has extracted from a standby cargo storage unit and placed on the packing surface. As in the case of the transfer station, the packing station preferably comprises an electronic circuit including a communications interface for communicating with the tracking system of the cargo logistics system, in particular receiving operation instructions therefrom. The electronic circuit of the packing station preferably also includes sensors or detectors for detecting position, size and/or fill-status of cargo receptacles. As in the case of the transfer station, a computer program is preferably mounted or installed on the electronic circuit for operating or operating a part of the packing station such as the packing surfaces and the transfer station. At the packing station, two or more cargo storage units are preferably arranged within reach of the transfer station. One of the cargo storage units receives packed cargo receptacles, packed, for example, by the picking robot, while the at least one other cargo storage unit is on standby to provide the transfer station and packing robot with empty cargo receptacles where needed. The cargo logistics method as described in this document may include bringing a cargo storage unit to a packing station, for example by a transfer station, and providing an appropriately sized cargo receptacle at the packing station, in particular transferring, by the transfer station, an appropriately sized cargo receptacle to a packing station, in particular a packing surface of the packing station. 
     The cargo logistics system, in particular its electronic tracking system, may further be configured to allocate the appropriate cargo receptacle size to a shipment, in particular the appropriate height, depth and/or width. For packing, for example, the electronic tracking system may be configured to determine which cargo receptacle is best suited for the cargo to be packed and which cargo receptacles are already full, for example in the case of second deliveries or already packed new deliveries, and which cargo receptacles in a cargo storage unit are free for packing. In a variation, the cargo logistics system, in particular the electronic tracking system, is configured to determine an appropriately sized cargo receptacle for packing based on order data from an order fulfilment and/or ERP system. 
     The cargo logistics system, in particular its electronic tracking system, may further be configured to determine the appropriate height for the packing surface at the packing station. To help achieve adequate ergonomics for service personnel or the appropriate height for a picking robot, the cargo logistics system determines the optimal height of the adjustable packing surface. The height is defined based on the height of service personnel or a picking robot along with the expected cargo or cargo receptacle height, for example based on order management information stored in the tracking system, in particular its electronic circuit. 
     Further, the cargo logistics system, in particular its tracking system, may determine the appropriate storage position for a cargo receptacle in a cargo storage unit. The cargo logistics system may be configured to determine in which storage position or on which level of the cargo storage unit the new cargo receptacle can be placed to optimize use of space in the cargo storage unit, for example following a packing process. This determination may be done by the cargo logistics system based on measures of the cargo receptacle, whereby the tracking system may be configured to measure, by a measuring device interconnected to the packing surface, the size of the cargo receptacle. The measuring device may be an optical and/or laser measuring device, for example. The determination may also be derived from account inventory information on occupied/vacant storage positions in the cargo storage unit. 
     Further, the cargo logistics system, in particular its tracking system, may be configured to assign destinations to cargo storage units based on shipment data, for example expected volume or number of cargo receptacles per destination, and/or historical shipment data analyzed by Artificial Intelligence (AI). For example, the electronic tracking system may be configured to determine which cargo storage units are destined for what destination, such as a unique delivery address, a distribution or sorting center, or a depot. 
     Further, the tracking system of the cargo logistics system may be configured to manage the transfer of cargo receptacles to cargo storage units by means of the at least one transfer station. Based on the cargo receptacles stored in first cargo storage units, the tracking system may be configured to determine the transfer of each cargo receptacle to a second cargo storage unit and storage level therein. Based on this determination, the at least one transfer station receives instructions on routes and stops throughout the sorting or transfer area. For each stop, for example, the electronic tracking system may be configured to determine which cargo receptacle shall be moved by the at least one transfer station from a first cargo storage unit and where it shall be placed in a second cargo storage unit. Based on this determination, the at least one transfer station receives instructions on the routes to follow. For speed and simplification, the route of the at least one transfer station may alternatively be determined by other electronic devices and algorithms, for example by machine-vision-based navigation and swarm logic making use of sensors of the transfer station&#39;s electronic circuit, where provided. 
     The described cargo logistics system has the advantage in that it allows for dynamic transfer and sorting of cargo. On the fly, the cargo logistics system may assign cargo storage units to destinations and cargo receptacles to cargo storage units and may at any time change assignments and rearrange cargo receptacles. 
     Given the re-useability of the cargo receptacles and provided the availability of dynamic information on cargo, cargo storage units, sizes, loads and localization thereof, the cargo logistics system is also configured to consolidate and coordinate cargo logistics by selecting, moving and in particular bringing together cargo receptacles at predefined locations. 
     In a variation, the cargo logistics system comprises a transport management system configured to select shipment methods based on a dynamic database of available delivery routes, delivery route capacity, current and historical shipment data, each of which may be determined by AI or from external data sources. The transport management system may be a part of the electronic tracking system or it may be separate and interconnected to the electronic tracking system. Using the dynamic data, the transport management system is configured to determine an optimal shipping method for cargo, such as last mile delivery or indirect routing via additional sorting centers or city depots. Participating in the determined optimal shipping method, the at least one transfer station is for example configured to receive instructions from the electronic tracking system to move occupied cargo storage units ready for shipment to a loading area and load them onto appropriate transport vehicles, such as transport vehicles used in long haul FTL, short haul LTL, courier, express, and/or private transport, said transport vehicles including autonomous vehicles such as drones, trucks, bikes, e-bikes, cars, aircraft and ships. 
     In a variation, the cargo logistics system, in particular its electronic tracking system is configured to determine the timing and sequence of cargo deliveries, wherein exact shipment information and storage location of cargo receptacles and cargo storage units on the transport vehicles are available to the electronic tracking system, in particular the transport management system. Based thereon, the electronic tracking system is configured to determine what cargo shall be delivered, how, and when. Compared to today&#39;s last mile delivery systems, where drivers manually sort cargo into delivery trucks, considerable time and labor savings are achieved. Localizing cargo receptacles and cargo storage units, the cargo logistics system can automatically update shipment status of each shipment. 
     The cargo logistics system also has the advantage that it can be configured to perform last minute changes or transport optimizations. For example, in case of deviations between expected and real volumes per destination or last minute changes of customers, the cargo logistics system, in particular its electronic tracking system, may be configured to instruct the transfer station or stations to sort, pick, rearrange, and/or single out cargo receptacles from cargo storage units having a destination for direct or express shipment routed separately.

       FIG. 1  shows a vehicle  15  for moving a cargo receptacle cart  10  as described in this document. The vehicle comprises a base member  16  containing the drive of the vehicle  15 , a holder in the form of a lifting member  17  for raising and lowering a cargo receptacle cart  10 , a set of wheels  18 , and a wireless control interface  19  of an electronic circuit. Although a lifting member  17 , in particular a lifting platform or fork  17  is shown, any holder or holding device suitable for holding a cargo receptacle cart  10  may be used. The base member  16  contains an electronic circuit comprising an installed computer program for controlling the robot based on instructions received via the wireless interface  19  that is configured to receive control instructions from a tracking system of an electronic circuit of a cargo logistics system described in this document and to send drive status information and holder status information to the electronic circuit. In addition, the vehicle  15  may comprise a number of sensors in order for it to navigate between locations for picking up and leaving cargo receptacle carts  10 . The computer program may comprise artificial intelligence (AI) functions and modules, based on, at least in part, machine learning. Essentially, the vehicle  15  may be considered an autonomous or semi-autonomous robot with means to hold, transport, and release a cargo receptacle cart  10 . Further,  FIG. 1  shows the vehicle comprising a transfer device  20  comprising a lift and at least one lifting platform  21  suitable for removing a cargo receptacle  1  from a first cargo receptacle cart  10   a  (see  FIG. 2 ) on to the lifting platform  21  and then moving the cargo receptacle  1  into a second receptacle cart  10   b  (see  FIG. 2 ). The transfer device  20  is configured to lift and lower the at least one lifting platform  21  and to rotate the respective lifting platform  21 , in which case the lifting platform  21  may be considered a turntable (see also  FIGS. 3 to 8 ). The transfer device  20  may also comprise push-pull devices, for example pistons, forks or grasping/holding arms, for transferring cargo receptacles  1  from a first cargo receptacle cart  10   a  to a second cargo receptacle cart  10   b  via the respective lifting platform  21 . Although the vehicle  15  shows the transfer device  20  to be arranged approximately midway on a base body  16 , other arrangements are possible, such as those shown in the following figures. 
       FIG. 2  shows the operation of the vehicle  15 , as described with reference to  FIG. 1 . The vehicle  15  drives to pick up first cargo receptacle cart  10   a  from a pickup position by means of a holder such as a lifting platform or fork  17 . The lifting platform  17  shown in this drawing is at a distance from the base body  16  of the vehicle  15  to improve stability of the first cargo receptacle cart  10   a  while it is being picked up, transported and set down. The lifting platform or fork  17  is suitable to be inserted into a section of the first cargo receptacle cart  10   a  between pairs of tracks  12  on different levels of the cart  10   a . After pickup, the vehicle  15  drives to and stops at a transfer position next to a second cargo receptacle cart  10   b . At the transfer position, the transfer device  20  of the vehicle  15 , by means of suitable push-pull devices (see  FIGS. 3 to 8  for further detail on the push-pull devices), moves cargo receptacles  1  from the first cargo receptacle cart  10   a  and onto the lifting platform  21 . The lifting platforms, in particular turntables  21 , are raised and lowered to appropriate positions where the transfer device  20 , by means of suitable push-pull devices, moves the cargo receptacles  1  into the appropriate available slots of the second cargo receptacle cart  10   b . When this operation is completed, the vehicle  15  returns to a pickup position and the process is repeated according to a sorting plan. For example, the second cargo receptacle cart  10   b  is assigned a certain destination, such as an intermediate holding area, for example a local post office.
