Each parent container 2 is provided with an identity tag 24, which is an electronic tag in one embodiment as shown in fig. 3C, wherein unique identity information of the parent container 2 in the logistics system, such as the number of the parent container 2, is recorded.

In this embodiment, the transport employs an AGV3, the AGV3 moving within the transfer space 102. The floor 113 of the storage unit 1 is a running surface of the AGV3, and is a schematic view showing a state where the AGV3 is stopped in the storage unit 1 as shown in fig. 5A to 5B. In this embodiment, and with reference to FIG. 1, the running surface of AGV3 is orthogonally provided with guide slots 1131. Because of the rectangular shape of floor 113, orthogonally disposed guide slots 1131 are parallel to respective bottom edges so that AGV3 can move unimpeded on floor 11 a. Two guide wheels 31 are provided at the bottom of the AGV3 for one guide slot 1131 to engage, as shown in fig. 5B, to prevent the AGV3 from deviating from the travel path during travel. In this embodiment, a set of orthogonal guide slots 1131 are provided in floor 113, or two or three sets may be provided, with corresponding guide wheels 31 also being provided at corresponding locations on the bottom of AGV 3.

For example, the plurality of sub turnover boxes can completely occupy the bottom area of the main turnover box through different arrangements, and can be safely stacked up and down in the main turnover box.

Logistics System embodiment

The invention provides a logistics system based on the sub-turnover box, which comprises: one or more mobile warehouses and/or fixed position warehouses and the primary and secondary turnover boxes; after the goods are received, the goods are placed in the sub turnover box, the sub turnover box is placed in the mother turnover box, and the mother turnover box is accommodated in a storage position unit, wherein the storage position unit, the mother turnover box, the sub turnover box and the goods are mutually related; the sub-containers with the goods inside are delivered to the consignee through a mobile warehouse or a vehicle.

The mobile warehouse and the fixed position warehouse are internally provided with the stereoscopic warehouse in the above description, and may comprise one or more warehouse location units according to the size. In the following description, a freight device having a large number of storage space units in the stereoscopic warehouse is referred to as a mobile warehouse, and the mobile warehouse may be a mini-truck as shown in fig. 22 or an urban circulation car as shown in fig. 23, or may be a device in which the stereoscopic warehouse is combined with other transportation devices. Such as a stereoscopic warehouse in combination with a ship, airplane, train, etc., may be referred to as a floating warehouse.

The logistics system of the present invention also includes a special end device, namely an express delivery robot as shown in fig. 20, which may have one or two storage location units inside the container. The logistics system also comprises a fixed-position warehouse, such as an express cabinet shown in fig. 21.

One or more storage position units are arranged in the packing box of the express robot and used for storing the primary and secondary turnover boxes. As shown in fig. 20, one parent container 2 is stored in the container, and one child container 7 is stored in the parent container 2. Wherein. When goods are taken, the express robot 8 carries the parent turnover box 7 comprising the child turnover box 7 corresponding to the goods specification to a goods taking position to take the goods, the goods taking position can be a goods delivery user, the goods are placed in the child turnover box by the goods delivery user and locked, the express robot 8 establishes the identity binding relationship between the goods and the child turnover box and the identity binding relationship between the child turnover box and the parent turnover box, namely the goods information is written into the identity label of the child turnover box, and the identity information of the current storage position unit is written into the identity label of the parent turnover box. If the goods taking place is an express cabinet, as shown in fig. 21, the express robot 8 opens the express cabinet to exchange a mother turnover box with the express cabinet. Then, the express robot 8 delivers the child and mother turnover boxes together to a mobile warehouse docked with the express robot at a designated docking location, such as a mini-truck shown in fig. 22, or a local circulating vehicle shown in fig. 23, or other cargo transportation devices with stereoscopic warehouse modules. When delivering goods, the express delivery robot 8 interacts with the goods receiving user, after the identity of the goods receiving user is confirmed, the lock of the sub-turnover box is started, the box cover is opened, and the goods are taken away by the goods receiving user. If the express delivery robot 8 can not be docked with the goods receiving user, the express delivery cabinet can be stored with the mother turnover box 2 loaded with the child turnover box 7 together, and the inside stereoscopic warehouse module with the same specification of the express delivery cabinet. When a goods receiving user takes goods, the main turnover box 2 with the sub turnover box 7 is sent out from the interior of the express cabinet, and after the goods receiving user opens the sub turnover box 7 to take the goods away, the main and sub turnover boxes 7 and the main turnover box 2 are recovered and prepared to be provided for an express robot or other mobile warehouses with demands.

As shown in fig. 22, a body warehouse module is integrated on the body of the mini-truck and the urban circulating vehicle shown in fig. 23, and a mobile warehouse is formed by the housing and the doors. The sorting device is further arranged inside the movable warehouse, the fixed position warehouse or the express delivery robot, and is used for sorting out goods to be transferred before the goods are in butt joint with the other movable warehouses, the fixed position warehouses or the express delivery robot. Similarly, as shown in fig. 21, the inside of the express cabinet is also provided with a sorting device, and when a user takes goods, the corresponding sub-turnover boxes are sorted out.

When the storage location unit where the parent turnover box 2 is located is changed, such as when the parent turnover box is transferred to one storage location unit in the mini truck 9a from the storage location unit of the express robot, or when the parent turnover box is transferred to another storage location unit from one storage location unit in a stereoscopic warehouse, the identity binding relationship between the identity label in the parent turnover box 2 and the storage location unit is changed. This operation can be operated by means of a device for changing the position of the parent container 2, such as an AGV. For example, when the AGV moves the parent turnover box 2 away from the storage location unit, the AGV releases the identity binding relationship between the parent turnover box 2 and the storage location unit, the position mark corresponding to the storage location unit in the identity label of the parent turnover box 2 is moved in the transportation process, and the identity binding relationship between the parent turnover box 2 and the new storage location unit is established when the parent turnover box 2 is placed in the new storage location unit.

And when the parent turnover box where the child turnover box 7 is located is changed, the identity binding relationship between the child turnover box 7 and the parent turnover box is changed. This operation can be performed by a device that causes the position of the tote 7 to change, for example, when the sorting device sorts the child tote, the sorting device changes the binding relationship between the sorting device and the parent tote, and the changing process is the same as the changing operation of the AGV, such as the processes of releasing, moving and establishing.

One procedure associated with logistics equipment for a cargo is as follows:

and step S1, placing the goods in the sub-turnover box, and at least recording goods information in the first identity label of the sub-turnover box. The goods information comprises information such as description of goods, receiving information, names, addresses, contact information and the like of shippers. Each sub-turnover box has a unique identity, when goods information is recorded in the identity label of one sub-turnover box, the corresponding association relationship between the goods and the sub-turnover box is established, and under a normal condition, the association relationship is not changed all the time from the time that the goods enter the logistics system to the time that the goods are transferred out of the logistics system.

And step S2, placing the child turnover box in the parent turnover box, and recording the identity binding information of the child turnover box and the parent turnover box on the first identity label of the child turnover box. Each mother turnover box is provided with a unique identity, the child turnover boxes are placed in the mother turnover box, and the first identity labels of the child turnover boxes record identity binding information of the child turnover boxes and the mother turnover boxes. If the parent turnover box for placing the child turnover box changes, the first identity label of the child turnover box records the change information, namely the identity binding information with the original parent turnover box is removed, and the identity binding information with the new parent turnover box is established.

And step S3, placing the parent turnover box in a position unit, and recording the identity binding information of the parent turnover box and the position unit on a second identity label of the parent turnover box. In the step, the position of the parent turnover box in the logistics system is determined by determining the association relationship between the parent turnover box and the storage location unit. The storage location units correspond to the logistics equipment where the storage location units are located one to one, for example, the identity information of the storage location units represents the identity of the stereoscopic warehouse where the storage location units are located and the number of the storage location units in the stereoscopic warehouse, and the identity of the stereoscopic warehouse is the identity of the moving warehouse or the fixed position warehouse. After the identity binding relationship between the parent turnover box and one storage location unit is determined, the logistics equipment where the parent turnover box is located and the specific position of the parent turnover box in the logistics equipment can be determined. When the storage position unit where the mother turnover box is located is changed, the identity binding relationship between the mother turnover box and the storage position unit is changed, namely the identity binding relationship between the mother turnover box and the original storage position unit is removed, and the identity binding relationship between the mother turnover box and the new storage position unit is established.

And step S4, associating the binding information of the library location unit, the parent turnover box and the child turnover box. For example, when the express robot receives a cargo and places the cargo into a child turnover box, the cargo information and the parent turnover box in which the child turnover box is located are written into the identity tag of the child turnover box, and the information is sent to the cargo management system, and the cargo management system records the cargo, the child turnover box, the parent turnover box, the storage location unit and the identity information of the express robot. When the express robot delivers the primary and secondary turnover box to the mini-truck together and stores one storage position unit in the mini-truck, the AGV carrying the primary turnover box in the mini-truck removes the identity binding relationship between the primary turnover box and the storage position unit in the express robot, establishes the identity binding relationship between the primary turnover box and the storage position unit in the mini-truck, and sends the change information to the cargo management system. And the cargo management system updates the logistics information in the current cargo, associates the cargo, the child turnover box and the parent turnover box with the new storage location unit and the mini-truck, and continuously updates the logistics information. The real-time position of each cargo in the logistics system can be determined through the associated information. The cargo management system can be located locally in a mobile warehouse or a fixed-position warehouse, and can also be located in a cloud.

The stereoscopic warehouse with different specifications is arranged in various logistics devices in the logistics system, goods are always in the sub-turnover box, the sub-turnover box circulates in different logistics devices along with the main turnover box, and changes of the main turnover box and the warehouse location unit in the circulation process are recorded in real time, so that the real-time position of the goods in the logistics system can be obtained, and data support is provided for supervision of the goods in the system. Because the mother turnover box is stored in the storage position unit in the stereoscopic warehouse, the goods cannot be overstocked and pushed together. The sub-turnover box has multiple specifications, can be suitable for goods of various shapes and sizes, and can protect the goods in the box from collision and damage in the transportation and carrying processes if structures such as anti-collision pieces are designed in the sub-turnover box for fragile goods according to requirements. When the goods are transported in the three-dimensional warehouse and are butted, the moving device provided by the invention, such as an AGV, is used for transporting the mother turnover box, the operation is stable, and the violent transportation and the violent sorting in the conventional logistics system are avoided. Therefore, the goods in the invention do not need various packaging tapes, packaging boxes, foam boxes, fillers and the like in the existing logistics system, and the primary turnover box and the secondary turnover box can be repeatedly used, so that the invention is more environment-friendly. Because the goods conveying devices are all stereoscopic warehouses with the same specification, the main turnover boxes for storing the sub turnover boxes can be commonly used in each goods conveying device, and therefore when goods are handed over, the AGV can directly convey the sorted main turnover boxes from the current goods conveying device to another goods conveying device. The unloading and loading in the existing logistics system are not needed any more, thereby greatly saving time. In addition, each butt joint link does not need personnel to intervene, so that contact between goods and people and contact between people and people are avoided.

The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention, and therefore, all equivalent technical solutions should fall within the scope of the present invention.
