Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without any creative effort, belong to the protection scope of the present invention.
In the following detailed description, reference is made to the accompanying drawings that form a part hereof and in which is shown by way of illustration specific embodiments of the application. In the drawings, like numerals describe substantially similar components throughout the different views. Various specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the present application. It is to be understood that other embodiments may be utilized and structural, logical or electrical changes may be made to the embodiments of the present application.
In the prior art, each link in a logistics chain has the following characteristics:
first, in the logistics chain, a warehouse for storing goods is an important link therein. Goods are basically placed on shelves in a traditional warehouse or a modern intelligent warehouse. A channel is reserved between the goods shelf and used for goods moving operation such as loading and unloading of goods. In some large warehouses, different cargo areas are also divided, such as entry and exit bays, sorting bays, and the like. In a conventional warehouse, the loading, unloading and moving of goods are basically realized by manual or manually-assisted carrying equipment (such as a forklift). In chinese patent application publication No. CN107577215A entitled "shelf and scheduling method and operational height method, center and system", a movable shelf is disclosed that can be moved in different areas within a warehouse, thereby improving the delivery efficiency of goods. Compared with the traditional warehouse, the intelligent warehouse has great improvement on the automation and the working efficiency of goods moving, however, no matter the traditional warehouse or the modern intelligent warehouse, enough space needs to be reserved in the warehouse to smoothly complete the moving of the goods, the storage space for storing the goods is less than half of the whole space of the warehouse, and the space utilization rate of the warehouse is not high.
Secondly, the handling of the goods by the logistics system, including the handling of the goods between the loading and unloading platforms and the warehouse and the inside of the warehouse, generally includes several ways, such as manual, semi-manual and fully-automatic equipment. Along with the development of science and technology, most logistics systems all adopt semi-manual work at present, and the staff utilizes equipment to carry the goods promptly. If the staff drives the fork truck, the goods are taken and stored by matching with the lifter. Most of the existing intelligent warehouses adopt agv (automated Guided vehicle) trolleys to carry goods. The AGV has various forms according to the size of a warehouse, the volume of goods and the size, for example, an AGV with a lifting frame is provided in a patent with an authorization publication number of CN203715182U and the name of the invention of "an AGV"; the patent application with the publication number of CN104317289A and the invention name of 'a novel forklift type AGV' provides a forklift type AGV which can rotate in situ and reduce the turning radius when turning. In addition, there are other types of AGVs, such as piggyback AGVs, traction AGVs, and the like.
The structures and the operation methods of the AGV are all suitable for the current logistics mode, and are mainly applied to various large warehouses, and the AGV runs in a channel between shelves or carries goods in different areas, such as a sorting area and a delivery area.
Again, during the movement of the goods from the place of origin to the place of consumption, the goods undergo various handling scenarios in various links of circulation. In order to avoid damage to the goods during transportation, different packaging means are required to package the goods according to the properties of the goods. For example, for some common small goods, they are packaged in cardboard boxes, plastic bags, tapes, hot melt adhesives, etc., and the cardboard boxes are filled with fillers to prevent the goods from shaking. Special packaging, such as custom-shaped foam boxes and the like, is also required to be added to fragile goods, such as glass products, ceramic products and the like. Thus, a small volume of goods is typically required, requiring a large amount of packaging material to enable the goods to be safely delivered to their destination. The excessive packaging mode not only occupies a large amount of storage and transportation space, but also wastes a large amount of packaging materials, and most of the packaging materials, such as plastic and foam, are non-recyclable materials, thereby bringing huge pressure and harm to the environment.
Again, sorting is another important link in the logistics chain. In order to improve the efficiency of transportation and distribution, a logistics system is usually provided with a multi-stage sorting center. For example, a piece of goods collected from a customer may be sorted through a sorting center, transported, sorted at a next level of the sorting center, transported … … until reaching a distribution station, and distributed from the distribution station to a destination. The sorting center comprises at least a warehouse for temporarily storing goods. The goods in storage are sorted by corresponding levels by manpower or equipment in the warehouse, then collected and transported to a designated area for storage, and are boxed when a transport vehicle arrives and transported from the sorting center to the next sorting center or distribution station.
With the development of science and technology, sorting technology is gradually improved. From original manual sorting to automatic sorting using various automated equipment. For example, a sorting device is disclosed in the publication No. CN102218404B entitled "logistics sorting system and method based on radio frequency, video and infrared identification and tracking", which includes a cargo delivery conveyor, a cargo conveying roller bed, a plurality of sorting port conveyors and a cargo identification device. The goods are thrown into the goods conveying roller way by the goods throwing conveyor and are conveyed into the corresponding sorting port conveyor after being identified by the goods identification equipment. For another example, patent application with publication number CN103949408B entitled "high-speed goods sorting vehicle and sorting system" provides a sorting scheme in which a pipelined sorting system is provided in a warehouse of a sorting center, a plurality of sorting ports are provided in a pipelined conveying path, and a sorting vehicle is used to load goods to be sorted. The sorting car discerns the goods at transfer passage removal in-process, pushes into the letter sorting mouth when the goods that will discern are through corresponding letter sorting mouth. There are also various other types of sorting equipment or sorting robots.
In the aforesaid various sorting techniques, need open up enough big region in the warehouse and place letter sorting equipment or letter sorting robot, wait to sort goods and the goods that sort to, after sorting, still need enough region to supply transportation equipment such as fork truck to collect the goods after the letter sorting, then transport the regional storage of goods through the transportation channel, wait for the shipment of leaving warehouse, therefore the warehouse need leave enough space for letter sorting, transportation. In addition, in the warehouse of the sorting center, the goods need to stay in the sorting center for a period of time from warehousing to ex-warehouse for sorting and waiting for ex-warehouse, and the stay time is closely related according to factors such as warehouse management technology, sorting technology, ex-warehouse transportation frequency and the like.
Finally, the goods taking and delivery at the end of the logistics still need to be completed manually, for example, express delivery personnel are required to drive a vehicle to a user for taking or delivering the goods. Although some express delivery robots have appeared, these express delivery robots need to cooperate with staff, put into and collect express delivery robot's goods by post house staff, and itself can not independently accomplish getting of goods and put.
The invention (including a plurality of patent applications related to the patent application) provides a revolutionary and novel logistics system, provides a plurality of breakthrough solutions different from the existing logistics system aiming at each link of a logistics chain, can reduce the retention time of goods, improve the transportation efficiency of the goods, reduce the use of fixed position warehouses, increase the space utilization rate of the warehouses, ensure the whole-course supervision of the goods and reduce the environmental pressure caused by excessive packaging.
According to one or more embodiments of the present invention, the logistics system of the present invention comprises: the system comprises a customer service system, a multi-stage midway delivery type logistics device and a plurality of logistics control modules, wherein in order to facilitate the description of the whole system, various logistics devices are named correspondingly in the following description so as to make the scheme easier to understand.
Fig. 1 is a schematic view of a multi-stage logistics apparatus transportation according to one embodiment of the present invention. In this embodiment, the terminal logistics devices include an express robot 8, a fixed-position warehouse (such as an express cabinet 10), a drone M1 (including small and large drones, shown as a drone), a mini-truck 9a, and the like. The chain line is an end logistics chain, and a user interacts with an end logistics device to enable goods to enter the logistics system from the user or come out of the logistics system to return to the user. The thin line is a secondary logistics chain, occurs between end logistics devices, and is used for goods transfer in a small area. The thick solid line is a three-level logistics chain, goods are transferred between the terminal logistics equipment and the three-level logistics equipment with the longer transportation distance, and the goods in a small range are transported by the three-level logistics equipment with the longer transportation distance in a long distance. The thick dotted line is a four-level logistics chain for transferring goods between the three groups of logistics equipment and intercity logistics equipment. In this level of logistics chain, goods are delivered by the tertiary logistics equipment to the inter-city logistics equipment, which transports goods from one city or country to another.
In some embodiments, the logistics devices include urban freight devices such as mini-trucks 9a and larger urban recycling trucks 9b, and international and inter-urban logistics devices, which may include cargo planes, inter-urban railways, long and short haul trucks, maritime cargo vessels, etc., depending on the distance.
In some embodiments, a courier robot is described as an example of an end logistics chain. It should be understood by those skilled in the art that the work of the courier robot may be replaced by a courier. This will not be described in detail in the following description herein.
In some embodiments, the logistics apparatus includes a fixed location warehouse and a movable cargo conveyance, each logistics apparatus has a unique identification, the movable cargo conveyance has a corresponding transportation distance range, and the entire cargo conveyance is divided into a plurality of levels according to the size of the transportation distance range, for example, three levels of international, intercity and city in general.
The city-level freight device can be divided into a plurality of different levels according to the size of a city and the transportation distance of the freight device. Fig. 2 is a schematic diagram showing the transportation distance of a city-level multi-level freight device. In this embodiment, the transportation distance S1 of the express delivery robot 8 at the end of the logistics is the shortest, so that the number of the express delivery robots is the largest, and the transportation range of the express delivery robot 8 can cover all user areas in the city as a whole. The mini-truck 9a is a second-level freight device, the transportation distance S2 of the mini-truck is greater than the transportation distance S1 of the express robot 8, the urban recycling truck is a third-level freight device, and the transportation distance S3 of the mini-truck is the largest urban transportation distance. The smaller the number required, the greater the transport distance. Of course, the number is also related to the amount of shipment. Under the condition of large object flow, the number of freight devices is large, and the more the freight devices are, the faster the flow of the cargos is. The logistics system has the advantages that the advantages are more obvious and the efficiency is higher when the material flow is larger.
In some embodiments, the transport area of each level of the freight device changes as it moves, and thus is more flexible in scheduling. When the goods are transferred, the butt joint position of the goods transport device and the butt joint goods transport device are determined by calculation only according to the logistics direction, the distribution of the goods transport device and the transportation direction of the goods transport device, so that the goods are transferred and butted more flexibly and quickly, the retention time of the goods is reduced, and the logistics efficiency is improved.
As will be appreciated by those skilled in the art, each level of shipping equipment includes a vehicle capable of accommodating the level of shipping. However, the present invention is not limited thereto. For example, a large freight transportation device, which is typically a secondary logistics chain, may also be used as an end logistics chain apparatus to pick up goods directly from a user. As another example, cargo may also be transferred directly to an aircraft, which is typically a three-level logistics chain cargo device, by a minivan as the end logistics chain, without passing through other levels of cargo devices.
In some embodiments, fixed-location warehouses may not be included in the logistics chain of the present invention. Goods are transferred between various levels of the physical chain without first being moved to a fixed location warehouse (or sorting center) and then removed from the fixed location warehouse by another shipping device. Therefore, the residence time of the goods can be greatly reduced, the logistics efficiency is improved, and the logistics cost is reduced. In some embodiments, fixed-location warehouses (including courier cabinets) may be added to the logistics chain of the present invention as an ancillary facility. For example, in the receiving and delivery links, if the user cannot temporally agree with the shipping device of the end logistics chain, the user experience may be reduced. The express delivery cabinet can compensate for the difference between the express delivery cabinet and the express delivery cabinet in time, and the satisfaction degree of a user can be improved. In some embodiments, fixed location warehouses (including suburban large warehouses) may be important components of the logistics chain, becoming an important ring in the logistics chain. Such fixed-location warehouses can serve as buffer warehouses for large quantities of goods entering and exiting the city to facilitate the dispatching of the freight devices. In some embodiments of the invention, the ratio of the number of items in the freight device to the number of items in the fixed-location warehouse is 50% or more, 80% or more, 90% or more, 95% or more, or 99% or more.
In some embodiments, the freight device comprises a stereoscopic warehouse, which can be used for both goods transportation and goods storage. In some embodiments, the freight device includes a stereoscopic warehouse, a storage device, a moving device, a sorting device, and a vehicle. The stereoscopic warehouse is carried by a vehicle. The specifications of the stereoscopic warehouse vary according to the type and carrying capacity of the vehicle. For example, when the vehicle is a small vehicle, an airplane, a ship, a smaller-scale stereoscopic warehouse is carried; when the transportation means is large-scale trucks, trains, cargo planes and marine cargo ships, the large-scale stereoscopic warehouse can be carried. Goods are arranged in the storage device in the stereoscopic warehouse. In some embodiments, the storage device comprises a child-mother tote. The goods are arranged in the subsidiary turnover boxes, and the main turnover box contains a plurality of subsidiary turnover boxes. The mother turnover box is accommodated in a storage space in a storage position unit of the stereoscopic warehouse. In some embodiments, the article moving device is, for example, a small and ultra-thin AGV, which is located in the article moving space of the storage location unit and is used for transporting the mother turnover box. In some embodiments, a different number of sorting devices are distributed in the stereoscopic warehouse, connected together with adjacent warehouse location units, and merged in the warehouse location units according to the size of the stereoscopic warehouse.
In some embodiments, the goods are placed in the child totes and the child totes are placed in the parent totes, which are stored in the bin position units in the stereoscopic warehouse. Therefore, the goods cannot be piled and pushed together. The sub-turnover boxes have various specifications and can be suitable for goods with various shapes and sizes; for some fragile goods, the structures such as anti-collision pieces are designed in the sub turnover box, so that the goods in the sub turnover box can be protected, and collision or damage in the transportation and carrying processes can be avoided. In some embodiments, when the goods are transported, for example, in the three-dimensional warehouse and the three-dimensional warehouse is in butt joint, the moving device provided by the invention, for example, the AGV, is used for transporting the mother turnover box, the operation is stable, and the violent transportation and the violent sorting in the existing logistics system are avoided. Therefore, the goods in the logistics system do not need various packaging tapes, packaging boxes, foam boxes, fillers and the like in the conventional logistics system, the problem of excessive packaging in the conventional logistics system can be avoided, and the logistics system is more environment-friendly.
In some embodiments, each cargo device is a stereoscopic warehouse with same-specification warehouse location units, and the main turnover box for storing the sub turnover boxes can be commonly used in each cargo device. When goods are handed over, the AGV can directly transport the sorted mother turnover boxes from the current freight device to another freight device. Links such as unloading and loading in the conventional logistics system are not needed, so that the time for loading and unloading goods can be saved. Moreover, each butt joint link does not need personnel intervention, so that the efficiency is high, and the contact between goods and people can be avoided.
In some embodiments, during transport, cargo is transferred from one shipping apparatus to another in a logistic direction. The different levels of freight devices form a plurality of logistic chain levels. The goods are delivered from the sending to the destination, pass through the plurality of freight devices with different transport distances, pass through or not pass through a warehouse at a fixed position, and finally reach a receiving user.
The present invention will be described in detail below with reference to specific examples.
In some embodiments, the stereoscopic warehouse has a high space utilization. Most of the space in the warehouse is used as a storage space for accommodating the storage device. The storage device is, for example, a storage box or a storage table. In one embodiment, the storage device comprises a child turnover box and a mother turnover box, the child turnover box is a closed device and is used for placing goods, and the child turnover box is placed in the mother turnover box. An object moving space for accommodating an object moving device, such as an ultrathin AGV, is arranged above or below the storage space. The storage device of the storage space is moved through the object moving device to complete the operations of goods entering, exiting, moving in the warehouse and the like. According to the specific structural design of the storage space and the article moving space, the volume ratio of the storage space to the article moving space can be greater than or equal to 4:1, or 5:1, or 6:1, or 7:1, or 8:1, or 9:1, or 10: 1. Therefore, the space utilization of the stereoscopic warehouse provided by the invention is far more than that of any traditional warehouse or modern intelligent warehouse in the prior art.
Embodiment of the library site Unit
In one embodiment, the present invention provides a standardized, modular storage unit that can be stacked together to form a space efficient stereoscopic warehouse.

In other embodiments, the support structure may be a fan-shaped structure connected to the upright and facing the storage space, wherein the arc of the fan-shaped structure is less than or equal to 90 degrees.
The bottom surface of the three-dimensional frame of the storage location unit is a whole bottom plate 113. In other embodiments, the bottom plate 113 may be hollowed or woven as required, thereby saving cost. In order to be able to determine the distribution of the goods in the three-dimensional space, each storage space unit is provided with an identity tag 14. As shown in fig. 3, the identity tag 14 may be an electronic tag located at a suitable position on the bottom plate 113, in which the identity information of the library location unit, such as a number in the library, is recorded.
The space inside the cube frame of the storage space unit 1, from the support block 12 to the top of the cube frame, comprises a storage space 101 for accommodating storage devices, such as the female turnover box 2 in this embodiment. Referring to fig. 4, a schematic diagram of a state where the parent container 2 is placed in the library unit 1 is shown. The purpose of providing the mother turnover box 2 is to be able to utilize the storage space of the storage location unit as much as possible. Since there are various possibilities for the stored goods in the specification, volume and shape, the goods of different specifications and different volumes can be orderly collected through the mother turnover box 2. The four supporting blocks 12 of the cubic frame support the bottom of the mother turnover box 2, so that the mother turnover box 2 can be stably stored in the storage space 101.
In one embodiment, the goods are placed in a sub-container (not shown). The child turnover box is placed in the parent turnover box 2. In some embodiments, the parent container 2 comprises a first body 20, the dimensions of which match the specifications of the storage space 101 of the storage location unit 1 in the present embodiment. As shown in fig. 5A, the height of the first body 20 of the main transfer container 2 matches the height of the storage space 101, and the top of the first body 20 is open for taking and placing the subsidiary transfer container from the top. In other embodiments, as shown in fig. 5B, the height of the first body 20 of the mother turnover box 2 is lower than the height of the storage space 101. In other embodiments, as shown in fig. 6A-6B, the first body 20 of the parent container 2 is in the shape of a storage table and comprises a rim 22 a. The positioning grooves 23a of various specifications are orderly arranged on the first body 20 and are used for accommodating goods of different specifications and different volumes.
In the foregoing three embodiments, the bottom of the first body 20 of the parent turnover box 2 has the conveying structure. As shown in the figure, the conveying structure may be a positioning structure 21 matched with a jacking mechanism of the article moving device, and the article moving device can jack the mother turnover box 2 from the bottom of the first body 20 of the mother turnover box 2. In some embodiments, each parent container 2 is provided with an identity tag 24, as shown in fig. 5C. In one embodiment, the identity tag is an electronic tag, in which the identity information of the parent turnover box 2, such as the number of the parent turnover box 2, is recorded.
In some embodiments, from the support block 12 to the bottom of the cube frame is a migration space 102. As a walking space of the object moving device. In one embodiment, the mover employs an AGV 3. The AGV3 moves within the transfer space 102. The floor 113 of the storage unit 1 is the running surface of the AGV3, and is a schematic diagram showing a state where the AGV3 is stopped in the storage unit 1 as shown in fig. 7A to 7B. In some embodiments, and with reference to FIG. 3, guide channel 1131 is orthogonally disposed on base plate 113. 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 engaging the guide slots 1131, as shown in fig. 7B, to prevent the AGV3 from deviating from the travel path during travel. In this embodiment, one set of orthogonal guide slots 1131 is provided on 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.
The guide slots and wheels are used to force the AGV to stay in the path without deviating from it during travel. According to similar thinking, can set up the sand grip on frame bottom surface 113, set up matched with recess on the AGV bottom surface, can play the effect of direction equally. The mechanical mode is low in cost, high in stability and easy to implement a control system.
In addition to these two mechanical configurations, other configurations may be used to guide AGV3, such as electromagnetic, laser, infrared, ultrasonic, UWB, or optical configurations. Any kind of guiding structure can be selected by those skilled in the art according to actual needs, and will not be described herein.
In some embodiments, to move the parent tote 2, a jack 32 is provided on the top of the AGV3, and the jack 32 is retracted within the top of the AGV3 when no load is being moved. When it is desired to move the load, the lift mechanism 32 extends from the top of the AGV3 and engages the locating structure 21 on the bottom of the parent container 2 to lift the parent container 2 from the support block as the lift mechanism 32 is raised.
In some embodiments, an electronic tag reader/writer (not shown) is provided on the outside of the lower surface of the base of AGV3 to read the identity tags of library level units 1; an electronic tag reader-writer (not shown in the figure) is arranged outside the upper surface of the base and used for reading the identity tag of the mother turnover box 2.
Fig. 8A-8B show a state in which one magazine unit 1 is loaded with mother turnover boxes 2 and stops one AGV 3. In order to move the mother turnover box 2, the AGV3 moves below the moving mother turnover box 2 and stops, the mother turnover box 2 is jacked up by the jacking mechanism 32 to separate the mother turnover box 2 from the supporting block 12, and then the AGV3 drives the mother turnover box 2 to move. In the magazine unit 1, a lifting space 103 is left for the parent container 2, so that the AGV3 can lift the parent container 2 from the supporting block 12, thereby separating from the supporting block 12 for easy movement. The height of the lifting space 103 is matched with the lifting distance of the jacking mechanism of the AGV3, and the mother turnover box 2 can be moved without hindrance after the jacking mechanism 32 of the AGV3 jacks up the mother turnover box, so that the lifting space 103 does not need to be too large, for example, the height of the lifting space 103 may be less than 5cm, or less than 3cm, or less than 1 cm.
In this embodiment, the thickness of the AGV3 used to move the load determines the size of the transfer space 102, and the thickness of the AGV3 is only a small portion of the height of the storage unit 1, so that the bulk of the storage space in the storage unit 1 is the storage space. According to the size and the load capacity of the mother turnover box 2, the space occupied by the inner components of the AGV3 and the load capacity of the inner components, the ratio of the thickness of the AGV to the height of the storage position unit 1 can be found in the range of 1/8-1/4 through calculation, namely, the space utilization rate of one storage position unit 1 can reach 75% -90%. When the object moving device adopts other modes, such as magnetic suspension and the like, the space utilization rate can reach 95%.

Library site unit embodiment III
FIG. 10 is a diagram illustrating a library site unit according to another embodiment of the present invention. In this embodiment, the storage unit 1c includes at least one cubic frame including four columns 111c, partitions 112c, and a bottom plate 113 c.

The volume of the article moving device 3c is not required to be large, so the height of the article moving space 102c is small relative to the height of the storage space 101c, and therefore the space in the storage unit 1c is mostly the storage space 101c, and the storage space 101c can reach over 75% of the whole space.
Corresponding to the storage location unit in the embodiment, the parent circulation box may also be configured as shown in fig. 11, wherein the first body 20c is provided with an openable and closable side door 201c at a side thereof, which can be freely set in two parts and respectively slide to the top and the bottom when opened, for taking and placing the child circulation box from the side. In this embodiment, the side door 201c is a roller door, and may be a slidable door made of other flexible materials. In the storage state, the side door 201c is closed, and when the sub-container is put in or taken out from the storage state, the side door 201c is opened. For example, at the time of receiving, delivering, and sorting, the side door 201c is opened.
The storage location unit provided by the invention is a modular and standardized storage unit, and a stereoscopic warehouse can be obtained when a plurality of units are stacked and connected together. In some embodiments, adjacent library site cells may share a pillar. That is, the vertical column of the stereoscopic warehouse can be shared by the warehouse location units adjacent to each other left and right or up and down. When a stereoscopic warehouse is manufactured, a plurality of storage units are also formed at the same time.

Because the extension length of the supporting structure for supporting the storage device is very small, the AGV cannot be prevented from moving. Thereby allowing the AGV to move freely across the entire transfer space in both the x-direction and the y-direction. For example, an AGV lifts up its storage device in one of the storage units and then moves to another storage unit; after positioning, the jacking mechanism is withdrawn, and the storage device is placed on the support structure of the new storage location unit, thereby completing the movement of the storage device.
Second embodiment of the stereoscopic warehouse structure

In this embodiment, a plurality of storage units are stacked and connected to form a two-layer stereoscopic warehouse. Of course, three or more layers may be used according to actual needs. In order to realize that the article moving device and the article storing device can move between different layers, the lifting system 4 is further included. The lifting system 4 comprises a support column 41 and a lifting platform 42. The lifting platform 42 is matched with the supporting upright 41, ascends or descends under the driving of the driving mechanism, and can be butted with a storage position unit at any height.

When it is necessary to transfer a parent container 2 on the lower layer, or a parent container 2 received from the outside, to a stock location unit on the upper layer. The AGV3 carries the storage device to the elevator platform 42 as shown in FIG. 16B. The elevating table 42 is driven by the driving mechanism to ascend, and when reaching the upper layer, the elevating table 42 stops ascending, and abuts against and is positioned with the storage unit of the upper layer. The AGV3 carries the parent container 2 toward the target library bit position. When the target library bit unit is reached, the jacking mechanism is withdrawn, and the mother turnover box 2 is placed on the supporting structure of the target library bit unit.

In this embodiment, the transmission mechanism includes a steering capstan 342 and a steering synchronizing wheel 344 located in the steering mechanism. In this embodiment, the steering driving wheel 342 uses a timing belt 343 to drive the steering timing wheel 344 to rotate. Since the direction of the output power of the steering motor 340 is radial, i.e. vertical to the bottom surface, and the steering mechanism requires horizontal power, a reversing mechanism is further included between the output shaft of the steering motor 340 and the steering driving wheel 342, as shown in fig. 26, the end of the wheel shaft of the steering driving wheel 342 is connected with a bevel gear 3451, and the end of the output shaft of the steering motor 340 is connected with a bevel gear 3452 matched with the bevel gear 3451, so as to change the axial power transmitted by the output shaft of the steering motor 340 into radial power, i.e. to change the transmission direction of the power from vertical to horizontal.
Fig. 27 is a schematic structural view of a steering mechanism according to an embodiment of the present invention. The steering synchronizing wheel 344 is connected to a bogie, which mainly comprises a bogie 3461 and a wheel carrier 3462.

The steering synchronizing wheel 344 is fixed to a boss of a fixed surface of the wheel frame 3462. The bottom of the bogie 3461 is fitted to the top of the wheel frame 3462 and is provided with coupling holes corresponding to the coupling holes of the fixed surface of the wheel frame 3462 to fix the bogie 3461 and the wheel frame 3462 together by a coupling member. The top of the bogie 3461 is fixed to the axle that drives the synchronizing wheel 334.
When the steering motor 340 rotates, its output shaft is configured to output axial power. Axial power is converted into radial power through the bevel gear, a steering driving wheel shaft coaxial with the bevel gear drives a steering driving wheel 342 to rotate, the steering driving wheel 342 drives a steering synchronous wheel 344 to rotate through a synchronous belt, the steering synchronous wheel 344 drives a bogie fixed with the steering synchronous wheel 344 to rotate, and the bogie 346 drives a roller wheel shaft, a roller synchronous mechanism connected with the roller wheel shaft, a reversing mechanism and a driving synchronous wheel 334 to rotate together, so that the rolling direction of a roller body 381 is changed, the in-situ rotation can be realized by matching the control of the driving mechanism, and the turning radius is 0. As shown in fig. 28, the view is rotated by 90 degrees with respect to fig. 25.
In the invention, the driving synchronizing wheel of the driving mechanism and the steering synchronizing wheel of the steering mechanism are coaxially fixed and are integrated with the roller assembly in the traveling mechanism through the bogie, thereby ensuring the miniaturization of the AGV, reducing the thickness of the AGV and reducing the occupation of space during transportation.
FIG. 29 is a schematic diagram of a jacking assembly structure according to one embodiment of the present invention. The jacking assembly 35 includes a jacking motor 350 for outputting jacking power. In order to transmit power to the jacking mechanism, a transmission mechanism is further included. In this embodiment, there are 4 push rods 32 and their associated structures, which are used as the transporting mechanism for the AGV to transport the goods and are uniformly distributed at the four corners of the base 30. In order to transmit the power of the jacking motor 350 to the 4 jacking rods 32 and the matched structure thereof synchronously, the invention comprises a jacking driving wheel 352 and 4 jacking synchronous wheels 354 positioned on the 4 jacking mechanisms, and the four jacking rods 32 are provided with guide wheels 321. Idler pulleys are respectively arranged on two sides of the lifting driving wheel 352 and the lifting synchronous wheel 354 for adjusting the direction of the synchronous belt 353.
FIG. 30 is a partial schematic view of a jacking assembly according to one embodiment of the present invention. In this embodiment, a reversing mechanism, such as a pair of engaged umbrella wheels, is provided at the end of the output shaft of the jacking motor 350 and the end of the axle of the jacking driving wheel 352 for changing the transmission direction of the jacking power.
Fig. 31-33 are schematic structural views of a jacking mechanism according to an embodiment of the present invention. In this embodiment, the jacking mechanism including the ram 32 further includes a gear 321, a transmission rack 322, a cross bar 323 at the side of the rack, and a locking solenoid valve 324. In order to transmit the power transmitted from the lift driver 352 to the gear 321, a reversing mechanism is further included. Such as a pair of bevel gears 3541 and 3542. Gear 321 is coaxial with bevel gear 3542 (the shaft is not shown).
When the jacking motor 350 rotates, the direction of the machine changing mechanism is changed, the jacking motor 350 drives the jacking driving wheel 352 to rotate, the jacking driving wheel 352 drives the jacking synchronous wheel 354 to rotate, the jacking synchronous wheel 354 drives the gear 321 to rotate through the reversing mechanism, and the transmission rack 322 meshed with the gear 321 rises or falls along with the rotating direction of the gear 321. As shown in fig. 31, the ram 32 is retracted. When the transmission rack 322 rises to a certain height, the cross bar 323 on the side of the rack props against the bottom end of the ejector rod 32, the cross bar 323 pushes the ejector rod 32 to rise along with the continuous rising of the transmission rack 322, the ejector rod 32 extends out of the upper surface of the base, and when the ejector rod 32 rises to a preset height, the jacking motor 350 stops rotating, and the transmission rack 322 stops rising. The lock solenoid 324 operates to lock the ram 32 from descending, as shown in fig. 33.
Although 4 jacking mechanisms are provided in the present embodiment, it should be understood by those skilled in the art that the number of the jacking mechanisms is not only 4, but also can be, for example, a plurality of jacking mechanisms, such as 8 jacking mechanisms. Or the lifting mechanism is adjusted, for example, the ejector rod is thickened or the structure of the top of the ejector rod is improved according to stress calculation, so that the area of the lifting mechanism is enlarged, and the number of the locking mechanisms with proper stress can be reduced to 3, 2 or 1.
In order to enable the AGV to accurately stop at a predetermined position in an unstable transport environment, the present invention further includes a positioning mechanism. Referring to fig. 33, in the present embodiment, the positioning mechanism is the positioning rod 39, and the mechanism for driving the positioning rod to ascend and descend adopts the structure for driving the push rod 32, so that not only the ascending and descending of the positioning rod 39 can be controlled, but also the space occupation can be reduced. In this embodiment, the top end of the positioning rod 39 is opposite to the cross bar 323, and when the cross bar 323 moves downward along with the transmission rack 322, the positioning rod 39 is pressed out from the bottom surface of the base. In this embodiment, the positioning rod 39 and the cross rod 323 can be integrally designed, that is, the movement of the positioning rod 39 moves along with the cross rod 323, and when the jacking motor 350 controls the cross rod 323 to ascend, the positioning rod 39 ascends synchronously to retract into the base. In another embodiment, a return structure, such as a return spring, may be designed for the positioning rod 39. The return spring is compressed while the cross bar 323 presses the positioning rod 39 down. When the cross rod 323 rises, the return spring drives the positioning rod 39 to return.
In the present embodiment, the driving motor 330, the steering motor 340, and the jacking motor 350 may be stepping motors or servo motors, so that the running distance may be precisely controlled. Because the lifting control distance of the jacking motor 350 is small and the moment is large, in order to achieve the control precision, a planetary reducer can be configured for the jacking motor.
In addition, whether to use the reversing mechanism can be determined according to the installation direction of the motor. In this embodiment, the output shafts of the various motors are parallel to the bottom surface, and thus a reversing mechanism is required. When the motor is rotated 90 degrees to make the output shaft vertical to the bottom surface, the reversing mechanism is not needed. In addition, the bevel gear is adopted for reversing in the embodiment, and other structures, such as a worm and gear structure, can be adopted according to the conditions of the inner space of the base and the like.
Fig. 34A-34B are schematic views of the construction of a guide wheel assembly in the guide mechanism. Referring to fig. 20B and 21A, the bottom of the housing of the base 30 is provided with an embedded guide channel 301, in which a guide wheel assembly is disposed. The guide wheel assembly includes a wheel frame 310, a guide wheel 31, a control lever 312, and a position sensor (not shown in the drawings). One end of the wheel frame 310 is fixed at one end of the guide groove 301 through a shaft 3100, the other end of the wheel frame 310 is fixed with the guide wheel 31, the middle position is connected with the tail end of the control rod 312 through a shaft 3120, the head end of the control rod 312 is fixed in the guide groove 301, the position sensor is arranged in the guide groove 301, and the position sensor is adjusted to trigger the guide wheel 31 to send a positioning signal after the guide wheel is put down and enters the guide groove of the driving surface. In one embodiment, as the guide wheel controller, according to the principle of an electromagnetic lock, the control lever 312 is configured as an electromagnetic lock, and the state shown in fig. 34A is a state when the control lever 312 is not energized, and at this time, the control lever 312 does not generate a suction force, and the guide wheel 31 is in a down state, and preferably, a structure such as a spring may be further provided inside or on the wheel carrier 312, and presses the wheel carrier 310 to prevent the guide wheel 31 from jumping upwards. Fig. 34B shows a state in which the lever 312 is energized, and the lever 312 generates suction force at this time, and the suction wheel holder 310 lifts the guide wheel 31. Referring to fig. 20B, in the present embodiment, there are two sets of guide wheel assemblies, two for each set, and two sets are vertically disposed. When the AGV moves in one direction, the two guide wheels 31 in that direction descend to engage with the guide grooves, as shown in fig. 34A, and the position sensor is triggered to send a signal; the other two guide wheels are lifted and retracted, and in the state shown in fig. 34B, the corresponding positioning sensors stop generating signals, so that the guide wheels and the guide grooves can be determined to be well matched, and the normal running of the AGV is ensured. When the AGV needs
FIG. 35 is an AGV stand-alone control apparatus according to one embodiment of the present invention, which is disposed inside the chassis 30, including: a task management module 305, a movement control module 302, and a conveyance control module 303. The task management module 305 communicates with the upper computer through the communication module 304, and is configured to receive the carrying task and send related information in the task completion process to the upper computer. The transport task at least includes an identification of the target cargo and a target position, and in this embodiment, the target position is a specific storage location unit. In one embodiment, the planned walking route, that is, the walking route from the current position to the transportation target position and then to the destination target position, may also be received from the upper computer. The task management module 305 transmits the target position or the planned walking route to the movement control module 302.
When only the target position exists, the mobile control module 302 calculates a walking route according to the current position and the position relation data stored in the mobile control module, and if the walking route is received, the driving motor and the steering motor are controlled to walk and/or steer according to the planned route according to the walking route. The walking route is composed of a plurality of straight line segments. When the AGV is applied to the stereoscopic warehouse, two adjacent straight line segments are 90 degrees, namely, the AGV travels in the vertical direction and the horizontal direction. In the straight line segment, the movement control module 302 determines the total number of turns of the driving motor 330 according to the distance of the straight line segment and the distance traveled by the roller assembly 38 per turn of the driving motor 330, and determines the required number of driving pulses according to the total number of turns, so that the traveling distance of the AGV can be accurately controlled. When the straight line segment is finished and the turning is needed to be 90 degrees, the movement control module determines the pulse number needed by the turning for 90 degrees according to the radius of the turning synchronizing wheel 344, controls the turning motor 340 to turn for 90 degrees, and meanwhile, the left guide wheel and the right guide wheel are placed down and the front guide wheel and the rear guide wheel are lifted. Since the synchronous wheel 334 is driven to rotate synchronously during steering, and the synchronous rotation of the synchronous wheel 334 drives the roller to move along, the corresponding pulse number is sent to the driving motor 330 at the same time when the pulse is sent to the steering control motor 340, so as to offset the corresponding difference when the synchronous wheel 334 rotates 90 degrees. Thus, the AGV wheels in this embodiment may be rotated in situ 90 degrees to ensure that the guide wheels 31 on the bottom of the base 30 still engage the bottom guide slots after steering.
When the AGV moves to a target position, such as a transport target position or a destination target position, the movement control module 302 sends a corresponding notification to the transport control module 303.
The conveyance control module 303 receives the identification of the conveyance target cargo and the target position transmitted from the task management module 305, and determines whether the current position is the conveyance target position or the destination target position based on the notification content when receiving the notification transmitted from the movement control module 302. And the electronic tag reader 3052 outside the lower surface of the base 30 reads the identity of the current position to determine whether the identity coincides with the target position in the handling task, and if not, sends a corresponding message to the task management module 305, and the task management module 305 communicates with an upper computer to determine the problem. If the electronic tags are consistent, the electronic tag reader-writer 3051 arranged outside the upper surface of the base 30 reads the electronic tags of the goods (such as the mother turnover box 2), and when the electronic tags are consistent with the target goods (such as the target mother turnover box) in the transportation task, the jacking motor 350 is controlled to work, and the jacking rods 32 are jacked up the goods. When the jack 32 is raised to a predetermined position, the goods are pushed away from the original placement position. When the AGV reaches the destination target position, the same identification and confirmation are performed, and then the jacking motor is controlled to work, and the jacking rod 32 is lowered to release the goods to the target position.
In one embodiment, a weight sensor (not shown) is also provided on the AGV, and when the lift pins 32 lift the load, the weight of the load can be sensed by the weight sensor, and the weight of the load is recorded by the task management module 305 and uploaded to the host computer.
In one embodiment, when the transportation environment is unstable, in order to accurately position the object when the object is stopped, the jacking motor 350 is controlled to control the positioning rod 39 to extend out from the bottom base 30, and after the accurate positioning, the jacking motor 350 is controlled to control the jacking rod 32 to ascend so as to transport the goods.
In one embodiment, the AGV also has various sensors for sensing distance and position, such as laser sensors, vision sensors, infrared sensors, etc.
In one embodiment, the AGV may also include a laser SLAM (synchronous positioning and mapping) or visual VSLAM system to assist the AGV in the tasks of path planning, autonomous exploration, navigation, etc. while transporting the cargo.
The AGV has various compact structures, for example, a part of the structure of the steering assembly, a part of the structure of the driving assembly and the rollers are integrated together, and the lifting structure of the ejector rods and the positioning rods is shared, so that the thickness of the AGV is greatly reduced, and the occupation of a three-dimensional space is reduced. The AGV has the advantages of small thickness, small occupied space, accurate operation and capability of being well suitable for novel stereoscopic warehouses. The device can also work normally in wagons, planes and ships which shake and bump, and can work in a linkage and cooperation manner in various mobile warehouses and fixed-position warehouses with the same specification.
Embodiments of a sorting apparatus
Each parent turnover box 2 in the stereoscopic warehouse comprises a plurality of child turnover boxes 7, and the destinations of goods in the child turnover boxes 7 may be the same or different. In order to improve the transportation efficiency, the invention sets a plurality of goods delivery processes in the goods flow process, thereby delivering a piece of goods from a delivery place to a destination. Therefore, during the distribution of goods, the target goods to be handed over need to be sorted out for each hand-over. Therefore, the invention provides a sorting robot and a sorting device, which are used for sorting the goods in the three-dimensional warehouse, and the AGV in the three-dimensional warehouse is matched with the sorting robot to sort the goods in the next warehouse according to the flow direction of the goods in the next warehouse.
It should be understood by those skilled in the art that although the sub-tote is shown as an example, the sub-tote may be replaced by an existing courier package. In other words, the parent turnaround box may also accommodate existing express parcels. Correspondingly, the sorting robot of the sorting device can be replaced by a mechanical arm for sorting the existing express packages.
Embodiment of the sorting apparatus
Fig. 36A-36B are schematic diagrams of a sorting apparatus applied to a stereoscopic warehouse according to an embodiment of the present invention. In the present embodiment, the sorting device 6 includes a support portion 61, a moving portion 62, and a sorting robot 5.
Fig. 36C-40C illustrate a sorting robot provided by an embodiment of the present invention. The sorting robot 5 provided by the present invention comprises a balance arm 50, a gripper module 51 and a motion driving part 52, wherein the balance arm 50 is used for keeping the moving process smooth. A gripper module 51 is attached to the end of the balance arm 50 for gripping goods. The motion driving unit 52 is connected to the balance arm 50, and drives the balance arm 50 to extend and retract.
Referring to fig. 37A, the balance arm 50 includes two or more arms 501 connected by a first joint 500. The one arm 501 includes at least an upper arm 503 and a lower arm 504 connected together by a second joint 502. For convenience of description, the ends of the upper arm 503 and the lower arm 504 connected by the second joint 502 are referred to as connecting ends, and the other ends are referred to as free ends, so that each arm has two free ends, and the second free end of the first arm is connected to the first free end of the second arm by the first joint 500.
Taking the upper arm 503 as an example, it includes four parallel connecting rods 5031, a connecting block 5032 is provided at the free end, and two shafts 5033 are provided thereon, and two ends of each shaft are respectively connected to one connecting rod 5031. In order to reduce the distance between the two parallel and parallel connecting rods and thus reduce the space occupied by the balance arm when the balance arm is contracted, one end of the two parallel and parallel connecting rods is designed to be arc-shaped, and the arc-shaped ends of the two connecting rods are respectively positioned at the free end and the connecting end, so that the two connecting rods 5031 can be arranged together when the balance arm 50 is contracted, and the upper arm 503 and the lower arm 504 are embedded together when the balance arm is contracted, thereby achieving the purpose of reducing the space occupied by the balance arm. As shown in fig. 37B, two arms 501 connected by a first joint 500 are juxtaposed and adjacent, and in the contracted state, an upper arm 503 and a lower arm 504 movably connected by a second joint 502 are fitted to each other in the contracted state.
As shown in fig. 37C, the second joint 502 includes two connecting plates 5021 and a set of tie rods 5022. The two connecting rods of the upper arm forming the upper plane are connected through a connecting plate, and a shaft seat 5023 is arranged on the connecting plate. Similarly, the lower arm also has the same shaft seat. A sliding rail 5024 is arranged on the connecting plate 5021. One end of the pull rod 5022 is fixed on the shaft seat 5023, and the other end is matched with the sliding rail 5024. When the lower arm 504 is opened downward under the control of the motion control unit, the upper arm 503 and the lower arm 504 move the pull rod 5022 in the sliding rail 5024, so as to contract or expand the upper arm 503 and the lower arm 504.
As shown in fig. 38A to 38C, the movement driving section 52 includes a driving case 520 in which a driving motor for controlling the support arm and a wire winding mechanism are provided. In this embodiment there are two arms in common, so there are two sets of motors and their wire winding mechanisms, i.e. the two arms are controlled by means of the wire ropes 521, 522 respectively. Referring to fig. 38A and 38B, the wire ropes 521 and 522 led out from the driving box 520 are mounted on the first free end connecting block 5032a of the first arm through guide wheels, and the end of the wire rope 521 is connected to the connecting block 5032B of the second free end of the first arm. To guide the wire rope 522 to the second arm, the wire rope 522 led out from the drive box 520 is connected to the connecting block 5032d at the second free end of the second arm via a guide wheel fixed to the connecting block 5032b at the second free end of the first arm and the connecting block 5032c at the first free end of the second arm.
Referring to fig. 37B, 38C and 38A, in the contracted state of the balance arm 50 as shown in fig. 37B, the internal motor of the driving box 520 drives the wire winding mechanism of the second arm to release the wire rope, resulting in the state shown in fig. 38C; at this time, the wire winding mechanism of the second arm stops releasing the wire rope, and the wire winding mechanism of the first arm is driven to release the wire rope, so that the state shown in fig. 38A is obtained. Since the balance arm 50 in this embodiment can control the single arm motion independently, it operates smoothly during extension and retraction. The design of the upper arm and the lower arm of the single arm can enable the height and the vertical stroke ratio to reach more than 1: 7.
Reference is now made to fig. 39A-39C, which are pictorial illustrations of a sorting robot gripper module in accordance with an embodiment of the present invention.

The opening and closing size of the grasping portion 511 can be adjusted by adjusting the position of the slider in the guide rail. In addition, the sliding of each gripping portion 511 may be individually controlled to accommodate the shape, size or position of different cargo gripping locations. The grasping portion 511 may grasp the goods in an adsorption mode and/or a mechanical mode. When the cargo is grabbed in the mechanical mode, the end structure of the grabbing portion 511 is correspondingly connected with the handle structure of the cargo. For example, in the present embodiment, the tip of the grasping portion 511 is provided in a concave structure. The handle on the sub-turnover box 7 is of a structure with a protruding outer edge and a concave middle part, which is called as a grabbing buckle 71, when the grabbing hand enters the concave part of the grabbing part of the sub-turnover box 7, the tail end of the grabbing part 511 is aligned with the grabbing buckle 71, the grabbing part 511 is controlled to move oppositely on the guide rail, so as to be buckled with the grabbing buckle 71, and when the balance arm 50 is contracted, the sub-turnover box 7 is grabbed.
The grasping unit may be of an adsorption type, for example, a vacuum adsorption type or an electromagnetic adsorption type. As to the specific structure of the suction type grasping portion, those skilled in the art can refer to the related art documents.
The recognition part 512 is provided on the gripper body 510 to recognize the sorted goods. According to the identification principle and the type of the identification tag of the sub-container 7, the identification part 512 can adopt technologies such as radio frequency identification, image identification, two-dimensional code identification and the like. In this embodiment, the identification unit 512 is an RFID reader/writer corresponding to the RFID identification tag of the sub transfer box 7. If the identification tag of the sub-container 7 is a two-dimensional code or a barcode, the identification unit 512 corresponds to a two-dimensional code/barcode reader/writer. In addition, the identification part 512 may also be an image identification unit, which includes a camera and an image identification subunit, where the camera collects an image of the goods or the goods identification tag, and the image identification subunit identifies the goods according to the collected image, or determines the distance from the current position to the goods.

In order to fit the space between the hand grip and the sorted goods well, in this embodiment, the hand grip includes a plurality of, for example, 4, shock-absorbing pressing plates 513, one end of each shock-absorbing pressing plate is connected to the hand grip body 510 through a shaft, and the shock-absorbing pressing plates 513 can rotate around the shaft, so that the shock-absorbing pressing plates 513 can be unfolded or folded to adapt to sub-containers 7 of different specifications and sizes. As shown in fig. 40A, when the contraction prevention pressing plate 513 is completely contracted, it is completely contracted at the lower portion of the grip body 510. Alternatively, as shown in fig. 40C, the cushioning press plate 513 is unfolded to accommodate the sub-containers 7 having a large area. In order to achieve sufficient rigidity and damping elasticity, the damping pressing plate 513 comprises an upper layer and a lower layer, the upper layer is a rigid plate, and the lower layer is a damping elastic plate, so that the requirements of rigidity and damping elasticity are met.
In addition, the sorting robot further comprises a control unit which is respectively in signal connection with the motion driving part and the gripper module and completes the sorting of the target sub-turnover box by cooperating with the gripper module and the motion driving part according to the received sorting tasks. For example, the operation of an internal motor of the driving box 520 is controlled, and the extension and contraction of the balance arm are controlled by the extension and contraction of the wire rope. For another example, the opening and closing size of the grasping portion 511 can be changed by controlling the retraction of a driver of the grasping portion 511, such as a motor or a wire rope, and controlling the sliding of the grasping portion 511 on the guide rail. As well as, for example, the control of a cushioned platen, etc.
The sorting robot further includes various sensors (not shown), such as one or more positioning sensors, collision avoidance sensors, laser SLAM (Simultaneous positioning and mapping) systems or visual VSLAM systems, for assisting the sorting robot in the tasks of planning, autonomous exploration, navigation, etc. when sorting goods.

The sorting operation flow of the sorting robot 5 is shown in fig. 42A to 42B. The sorting robot 5 is in a standby state, it is above the first sorting unit 60, wherein the first sorting unit 60 has the parent circulation box 2 placed therein, and the parent circulation box 2 has the child circulation box 7 placed therein (not shown in fig. 41A to 41C, see fig. 41E). As shown in fig. 41A, the sorting robot 5 is in a retracted, standby state.
A process of sorting the goods by the sorting device 6 is shown in fig. 42A-42B, and includes the following steps:
in step S6101, the balance arm is deployed, the gripper module 51 is lowered, and the lowering height is monitored. The motor inside the movement driving part 52 drives the wire winding mechanism to release the wire rope of the second arm, so that the lower arm of the second arm is extended downward, and the sorting robot 5 is in the state shown in fig. 41B (the wire rope is not shown, see fig. 38C or 36C). The motor inside the movement driving part 52 drives the wire winding mechanism to release the wire rope of the first arm, so that the lower arm of the first arm is extended downward, and the sorting robot 5 is in the state shown in fig. 41C (the wire rope is not shown, see fig. 38A). During the process of unfolding the balancing arm, the sorting robot 5 can also be rotated to adjust the correspondence relationship with the sub-containers 7, as shown in fig. 41D.
During the lowering of the balancing arm 50, the distance from the sub-containers 7 is monitored by an identification unit built into the sorting robot 5, such as a camera, a laser SLAM system or a visual VSLAM system.
Step S6102, confirming whether the gripper module 51 has reached a suitable height, for example, about 20 to 50mm from the top of the sub-turnaround box 7. If yes, step S6103 is executed, and if not, step S6101 is returned to.
Step S6103, the sorting robot 5 incorporates an RFID reader to read the RFID information of the target sub-container 7.
In step S6104, it is determined whether the target sub-container 7 is a designated target, and if so, in step S6105, the identity information of the sub-container is uploaded to the logistics control module system, and then step S6107 is executed. If not, step S6106 is executed.
Step S6106 is to adjust the height and position of the sorting robot 5, set the other sub-circulation box as a target, and return to step S6103.
Step S6107, opening the damping pressing plate 513 to a proper angle according to the size of the target sub-container 7, which is not larger than the size of the sub-container.
In step S6108, the balance arm continues to descend and fine-tune the horizontal coordinate until the sensor senses that the gripping portion 511 and the claws 71 of the target sub-container 7 are concentric and reach the gripping height.
In step S6109, the grasping portion 511 grasps the grasping portion 71. Here, when the grasping portion 511 and the clasps 71 of the target sub-circulation box 7 are concentric and reach the grasping height, the grasping portion 511 is contracted to grasp the clasps 71. As shown in fig. 41E.
Step S6110, the sorting robot 5 has an internal RFID reader to update the RFID information of the parent turnover box 2, that is, the identity binding relationship between the target child turnover box 7 and the parent turnover box 2 is released, and the information is uploaded to the logistics control module of the cloud system.
Step S6111, the balance arm of the sorting robot 5 lifts the target sub-turnover box 7 to a proper height, for example, 2-5cm higher than the top of the mother turnover box 2. As shown in fig. 41F.
In step S6112, the sorting robot 5 moves horizontally to the second sorting unit. Wherein the second sorting unit is adjacent to the current first sorting unit in the y-direction. The driver 622 synchronously drives the two side sliding rails 621 on the supporting portion to extend forward, and the cross beam 623 fixed with the sliding rails drives the sorting robot 5 to extend forward, as shown in fig. 41G, until the second sorting unit is horizontally moved, as shown in fig. 41H.
In step S6113, the sorting robot 5 determines that the current position is above the second parent turnover box through the sensor.
In step S6114, the balance arm 51 of the sorting robot 5 descends into the second parent turnover box, and fine-tunes the horizontal coordinate, while monitoring the current position of the target child turnover box 7. In one embodiment, the sorting robot 5 may establish a 3D coordinate system in its sorting area, and determine that the target sub-tote 7 reaches the designated position where it should be put by monitoring the 3D coordinates of the target sub-tote 7.
Step S6115, determining whether the target child turnover box 7 reaches the designated position, if so, in step S6116, the grabbing part 511 releases the grabbing buckle, places the target child turnover box 7 at the designated position in the second parent turnover box, binds the identity relationship between the target child turnover box 7 and the second parent turnover box, and uploads the identity relationship to the logistics control module. If the target sub-circulation box 7 has not reached the specified position, the process returns to step S6114.
In step S6117, the balance arm retracts to return to the standby state.

The balance arm is contracted to drive the sub turnover box 7 to move out of the main turnover box 2 a. The driving rail 621a is extended in the y direction to drive the sorting robot to move toward the second sorting unit. The sorting process is the same as the first embodiment, and is not described herein again.
Fig. 44 is a functional block diagram of a sorting apparatus control system according to one embodiment of the present invention. In this embodiment, the sorting apparatus 6 may further include a sorting subsystem 66 for performing sorting tasks. The sorting subsystem 66 includes, among other things, a communication module 661, an identification module 662, and an information modification module 663 and a motion control module 664. The communication module 661 is configured to receive a sorting task, where the sorting task at least includes a target child turnover box list, and the target child turnover box list at least includes target child turnover box identity information, originally bound first target parent turnover box identity information, and second target parent turnover box identity information for placing a target child turnover box; the identification module 662 corresponds to the identity tags of the parent turnover box and the child turnover box, and when the identity tags are RFID tags, the identification module is an RFID reader-writer. The first target parent turnover box and the target child turnover box are arranged in the sorting unit, and can be the same as the identification part of the sorting robot 5 and used for identifying whether the parent turnover box and the child turnover boxes in the sorting unit are the first target parent turnover box and the target child turnover box; when the target child turnover box is caught from the first target parent turnover box, the information modification module 663 releases the identity binding relationship between the target child turnover box and the first target parent turnover box; and when the target child turnover box is placed in the second target parent turnover box, establishing the identity binding relationship between the target child turnover box and the second target parent turnover box. The motion control module 664 is used for controlling the sorting robot 5 and the moving part 62 to complete the action flow required by one sorting task. One of the sorting processes is shown in fig. 41A-41H. And will not be described in detail herein.
The sorting robot provided by the invention is suitable for a stereoscopic warehouse, the occupied warehouse space is small, and the time and the place for sorting goods are not limited. The parallel arm structure of the sorting robot can keep the posture of the sub-turnover box stable during grabbing and carrying, and the deformable elastic damping pressing plates corresponding to the sub-turnover boxes of various models and sizes are further arranged, so that the sub-turnover box can be effectively prevented from shaking during carrying. The gripper module of the sorting robot can be designed into an adsorption type or a mechanical type, and can be matched with an intelligent identification part, such as a camera, an RFID (radio frequency identification device), a two-dimensional code card reader and other various sensors, so that the sub-turnover box can be accurately identified and grasped. The motion driving part in the sorting robot can rapidly and stably control the extension, contraction and movement of the robot, and the synchronous toothed belt adopted in the control can realize the functions of low torque, miniaturization and accurate positioning of a transmission device.
As shown in fig. 45, a three-dimensional warehouse structure with a storage device, a transfer device, and a sorting device built therein is shown. The structure of the stereoscopic warehouse is as shown in the aforementioned stereoscopic warehouse structure embodiment, and the description is not repeated here. Goods in the warehouse are arranged in the sub turnover boxes 7, and the sub turnover boxes 7 are arranged in the main turnover box 2. The mother turnover box 2 is placed in the storage space in the storage position unit of the stereoscopic warehouse. The library bit unit has unique identity information, for example, a number is taken as identity information, which represents the position of the library bit in the stereoscopic warehouse, for example, the number C0F11001 represents the first library bit in the first column of the layer, C0F22001 represents the first library bit in the second column of the second layer, C0F34002 represents the second library bit in the fourth column of the third layer, and the like, wherein the first three characters represent the identity of the logistics warehouse. In order to obtain the identity information of the storage location unit, an electronic tag RFID or a two-dimensional code is used as the identity tag of the storage location unit, wherein the number information of each storage location unit is recorded. In the following description, RFID is taken as an example. Similarly, the parent container 2 and the child container 7 each have unique identifiers, for example, numbers with letters, numbers, and the like. For example, the identity of the child container 7 is a300x180x180, and the identity of the parent container 2 is M500B700C 100. Therefore, the unique position information of a piece of goods in the whole logistics system can be determined by binding the identity relationship of the child turnover box, the parent turnover box and the specific storage location unit of the stereoscopic warehouse. Moreover, when any link is changed, such as the change of a mother turnover box, the change of a storage location unit, the change of a stereoscopic warehouse and the like, the binding relationship of the identities is changed in real time, so that the accurate real-time position information of the goods can be ensured. A small and ultrathin AGV3 in the stereoscopic warehouse is positioned in the article moving space of the warehouse location unit 1 and used for carrying the mother turnover box 2. According to the scale of the stereoscopic warehouse, sorting devices 6 with different numbers are dispersed in the stereoscopic warehouse, connected with adjacent warehouse location units and fused in the warehouse location units. The sorting device 6 comprises two sorting units 60 which are connected to other storage space units 1 in the stereoscopic warehouse. Sorting is accomplished in cooperation with sorting apparatus 6 by controlling the transport of parent containers 2 by a transfer apparatus, such as AGV3, within the warehouse.

In this embodiment, the transmission mechanism includes a steering capstan 851 and a steering synchronizing wheel 852 located in the steering mechanism. In this embodiment, the steering driving wheel 851 drives the steering synchronizing wheel 852 to rotate by using a synchronizing belt 853. Since the direction of the output power of the steering motor 850 is radial, i.e. vertical to the bottom surface, and the steering mechanism requires horizontal power, a reversing mechanism is further included between the output shaft of the steering motor 850 and the steering driving wheel 851, and the structure thereof is as shown in fig. 62, and a pair of bevel gears which are mutually matched are adopted to change the axial power transmitted by the output shaft of the steering motor 850 into radial power, i.e. to change the transmission direction of the power from vertical to horizontal.
The steering synchronizing wheel 852 is connected with a bogie, see fig. 65, which mainly comprises a bogie 8531 and a wheel carrier 8532. The wheel carrier 8532 is matched and fixed with a bracket 8451 outside a secondary reversing mechanism of the driving assembly. Or the wheel carrier 8532 and the bracket 8451 as one part. The top of the wheel frame 8532 is a fixed surface, the top is provided with a connecting hole, such as a screw hole, the periphery is provided with a boss, and the steering synchronizing wheel 852 is fixed on the boss of the fixed surface of the wheel frame 8532.

When steering motor 850 rotates, its output shaft is configured to output axial power. Axial power is converted into radial power through the bevel gear, a steering driving wheel shaft coaxial with the bevel gear drives a steering driving wheel 851 to rotate, the driving wheel 851 drives a steering synchronous wheel 852 to rotate through a synchronous belt, the steering synchronous wheel 852 drives a steering frame 8531 fixed with the steering synchronous wheel 852, the steering frame 8531 drives a wheel frame 8532, the wheel frame 8532 drives a support 8451, the support 8451 drives a roller wheel frame 822, the whole roller body 821 is further driven to rotate together, and therefore the rolling direction of the roller body 381 is changed. Fig. 69 is a schematic view of fig. 68 rotated at an angle.
Because each roller assembly is matched with one set of driving assembly and one set of steering assembly, various walking modes can be realized through the independent control and matching of each roller assembly. For example, when the roller bodies of the four roller assemblies rotate forwards or backwards simultaneously, the express delivery robot can move forwards towards the walking direction or move backwards. By controlling different rotating directions of the roller assembly, the body of the express robot can be fixed, if the express robot still faces the original walking direction, but the roller body under the base can rotate in situ. Rotate 45 degrees through control roller assembly in the time, can make express delivery robot's fuselage translation, still face original walking direction, but the direction of roller assembly and original walking direction are the direction slant of certain contained angle (like 45 degrees). For example, the body of the express robot can be fixed and still face the original walking direction by controlling the roller assembly and rotating 90 degrees at the same time, but the direction of the roller assembly and the original walking direction form a 90-degree included angle, namely, the express robot moves transversely at the moment.
The different walking modes are used for adapting to various conditions in the walking route. For example, when the original walking direction has an obstacle, the express delivery robot can change the forward straight line into the lateral movement towards the left or the right, and then return to the original route to travel when the express delivery robot bypasses the obstacle. In the whole walking process, the machine body does not need to be rotated, so that the shaking caused by rotating the machine body is reduced, and the walking stability of the express robot is ensured.
The interaction mechanism 83 is located above the cargo box 81, and its signal lines, power lines, etc. are connected to the electrical box of the base through the wiring channel in the column 812 provided at the rear side of the cargo box bottom plate 810.

For example, a top cover which is controlled independently is provided corresponding to a mother turnover box in the container, and the top cover corresponds to a mother turnover box for taking out goods and a mother turnover box for delivering goods. When taking the goods, only opening the top cover of the corresponding mother turnover box; when the goods are delivered, only the top cover of the corresponding delivery mother turnover box is opened, so that the safety of the goods can be ensured.
Fig. 70 is a functional block diagram of a control device of the courier robot according to one embodiment of the present invention. The control device 88 includes a communication module 880, a task management module 881, a walking control module 882, and an interaction control module 883. The communication module 880 is configured to communicate with the cloud management system, and transmit information, data, and the like to each other. The task management module 881 is configured to receive the pick/deliver task and the docking information through the communication module 880, and send the corresponding pick/deliver task information to the cloud management system. The cloud management system maintains logistics information of the goods, wherein the logistics information comprises identity information of sub-containers loaded with the goods in the logistics process, identity information of mother containers loaded with the sub-containers and change occurrence time of the mother containers, identity information of express robots or freight devices transporting the goods and change time of the express robots or the freight devices.
The picking task received by the task management module 881 includes partial information in the order, such as: the information of the delivery user comprises names, telephones, delivery addresses and the like, and also comprises cargo information, such as cargo names, sizes, sub-containers to be used and the like. And when the cloud management system sends the goods taking task, whether the current express robot has a proper sub-turnover box which meets the specification or not is also determined. If not, the position of the sub-turnover box, such as a surrounding post house, a stereoscopic warehouse inside an express cabinet or a nearby passing freight device, is obtained, and the box taking position and the goods taking task are sent to the express robot together. The task management module 881 also collects information during the pickup process and sends the information to the cloud management system. For example, the relationship between the identities of the goods and the child turnover box, the identities of the child turnover box and the parent turnover box, and the identities of the parent turnover box and the express robot, and the like. The delivery task received by the task management module 881 includes order information of the goods, such as recipient information, such as recipient address, recipient identity information, etc.
The walking control module 882 is configured to control the driving motor and the steering motor to walk and/or steer according to a planned route according to a walking route. The walking route can be received from the cloud management system, or the walking route can be automatically calculated according to the target position and road condition information monitored by the laser navigation SLAM or visual navigation VSLAM system. Thus, in one embodiment, the control system further includes a geographic location module 884 to obtain geographic information between the current geographic location and the target locations to provide geographic location information for calculating the travel route. Meanwhile, the real-time geographical position and road condition information is reported to the cloud management system through the communication module 880.
The walking route comprises sidewalks for pedestrians, such as urban roads and bridges. In order to sense surroundings such as pedestrians, vehicles, traffic lights at intersections, etc. during walking, the control device further includes various sensors, such as various visual sensors, sound sensors, distance sensors, etc., and their respective corresponding processing units. The walking control module 882 is internally provided with walking rules and corresponding control modes, and adopts the corresponding control modes according to information acquired by the sensors in the walking process. Such as stopping, decelerating, avoiding, accelerating, increasing power, changing routes, etc. The camera and its image processing unit in the interactive mechanism can also be used as a video sensor, or another independent visual sensor composed of a pattern sensor and a light projector. The vision sensor can acquire the whole image information of the front and the periphery of the vehicle, and can determine whether an obstacle exists in the front, whether a traffic light exists in the front or not after the image information is processed. The sound sensor can distinguish abnormal sound, and the abnormal condition can be judged by matching with the vision sensor. The distance sensor is, for example, a laser ranging sensor, a photoelectric sensor, an infrared sensor, or the like, and can measure a distance to a target object or an obstacle. For example, in the traveling road, the front road can be judged to be an uphill slope through the vision sensor, and at the moment, each roller assembly needs to be adjusted, so that the express robot can safely walk on the slope. If the front obstacle is judged to be in front through the vision sensor, the size of the obstacle can be judged, and an avoidance measure is determined. For example, if the obstacle is only a pedestrian, the distance that the pedestrian can pass is made in advance. After the pedestrian passes through, the pedestrian returns to the original route. If the front obstacle occupies the entire road, the route is changed one block ahead.
The sound sensor can collect surrounding sound and judge whether a response is needed. For example, when sharp ground friction sound is collected, it can be determined that a traffic accident may occur according to the tone, size, distance and direction of the sound, and the current accident can be determined by configuring the image collected by the visual sensor. And then the distance between the accident site and the accident site can be determined through a distance sensor, such as a laser range finder, and whether avoidance is needed or not is judged. The distance sensor, such as a laser distance measuring sensor, a photoelectric distance measuring sensor, etc., can detect objects far ahead or objects near.
For different road conditions, the walking control module 882 controls the output power of the driving motor or the steering motor to adapt to the frictional resistance of different roads. For example, when the electric vehicle runs on a road surface with large friction resistance, such as snow, uneven stone and the like, the output power of the motor is increased, and when the electric vehicle runs on a road surface with smooth ground, such as tiles, ice and the like, the output power of the motor is reduced, and the possibility of skidding with the center of gravity lost is reduced through the direction of the roller.
The interactive control module 883 is connected to the walking control module 882, the task management module 881 and the communication module 880, acquires the pickup/delivery task information and the docking task information from the task management module 881, and completes the docking of the pickup or delivery and the goods according to the pickup/delivery task docking task and the corresponding interactive scene.
Specifically, as shown in FIG. 71, a schematic block diagram of an interactive control module according to one embodiment of the present invention is shown. The interactive control module 883 includes an operator unit 8831 to open the cargo container as instructed, for example, in a pick/deliver scenario, to open the top cap 813 at the beginning, to close the top cap 813 at the end, and to lock the top cap 813 to secure the cargo. In the cargo docking scenario, the front cover 814 is opened at the beginning and the front cover 814 is closed at the end to secure the cargo. The operation indicator is used for indicating a target sub turnover box in the main turnover box by operating the laser indicator according to the indication of the user, or activating the indicator of the sub turnover box to emit light or sound to indicate the user that the user is the target sub turnover box.
The interactive control module 883 further includes a voice unit 8832, including a voice module, a speaker and a microphone, for interacting with the shipper or the consignee, guiding the shipper to perform the shipment process, and guiding the consignee to perform the consignee process. For example, checking the identity of the shipper or recipient, checking the goods, prompting the shipper or recipient to view a demonstration video, giving a reminder when the shipper or recipient has an error in operation, and the like.
The interactive control module 883 also includes a video unit 8833, including an image capture device (e.g., camera 831) and a video output device (e.g., display screen 832). The camera 831 collects video images all the way during delivery and receipt, and sends the video images to the cloud management system through the communication module 880. In addition, the condition in the mother turnover box can be collected through the camera 831 to monitor the operation of the delivery user or the receiving user. The video output device plays relevant videos, such as greeting videos interacted with a shipping user or a receiving user, operation demonstration videos, logistics process demonstration videos, and the like. Through the interaction with the user in the modes of voice and video, necessary information can be vividly output to the user and questions of the user can be answered.

In some embodiments, during the transportation process of the goods, the goods are transported by using multiple levels of freight devices within the respective corresponding transportation distance ranges, the goods are transferred from one freight device to another freight device according to the distribution positions and the logistics directions of the freight devices, and the transfer process is continuously repeated until the logistics destination is reached. Since the goods need to be transferred between different freight devices, the goods need to be sorted out of the original freight device before being transferred. The sorting of the invention takes place in the freight device in the course of the freight transport.
According to the flow direction of the goods, the goods are sent out from the delivery user to enter the logistics system, and the flow of the goods is ended according to the receiving of the end logistics equipment, the transferring of different freight devices in the middle and the dispatching of the end logistics equipment until the receiving user receives the goods.
The logistics process of the invention is described below starting from the end of the logistics system.
At the logistics end, according to different logistics devices at the end, a plurality of delivery and receiving modes are provided, for example, delivery and delivery are finished by an express robot and a delivery user in an interactive way; the delivery user utilizes the express cabinet and the unmanned aerial vehicle to finish delivery and receiving by self; and the express delivery personnel drive the mini-truck to finish delivery and delivery interactively with a delivery user. The following description is made for different scenarios:
scene one: the express robot gets the goods to the delivery user
Fig. 75 is a flowchart of an operation method of the express robot in picking up goods according to an embodiment of the present invention. The express delivery robot goods taking operation method provided by the invention comprises the following steps:
in step S81a, a mother container having a predetermined sub container built therein is loaded into the storage layer in the container. When the express delivery robot takes the goods and receives the goods taking task, the specification information of the sub turnover box required by the taken goods is also included. The cloud end can determine whether the express robot currently has a sub-container with a required specification, and if not, the cloud end sends an address for acquiring the sub-container to the express robot, such as a nearby fixed-position warehouse, an express cabinet, or other freight devices passing through the area. If the express robot currently has a sub container with the required specification, the step S82a is executed. If the sub-turnover box meeting the specification does not exist in the main turnover box in the express robot, the sub-turnover box needs to be acquired at the specified address. When the child turnover box is obtained, the express robot exchanges the parent turnover box in the container and the child turnover box in the container with the parent turnover box at the exchange place and the corresponding child turnover box meeting the specification. Further, the express delivery robot can get a plurality of goods to a plurality of goods of getting the goods place once, therefore, when starting, has placed the sub-turnover case that corresponds a plurality of goods in its packing box.

And checking whether the butt-joint person and the goods conform to the information in the goods taking task or not according to the goods taking task information. Such as shipping user name, phone, item name, characteristics, etc.
In step S832a, after the information is checked, the courier robot opens the top container cover, prompting the user to find and open the child container. And meanwhile, an operation demonstration video of opening the sub-turnover box and putting goods is played on the display screen. If when having a plurality of sub-turnover boxes in the box of mother turnover, express delivery robot can come the suggestion user through different modes and open corresponding sub-turnover box. For example, a luminous indicator is arranged on the sub-turnover box, the express robot activates the luminous indicator corresponding to the sub-turnover box to make the luminous indicator emit light and flash, or informs the receiving user of the number on the shell of the sub-turnover box through voice; or sending light spots to the corresponding sub-turnover boxes through a cursor indicator.
Step S833a, after the user correctly places the goods in the sub-container, closes, weighs, charges, and confirms delivery of the goods, the express robot locks the sub-container, establishes an identity binding relationship between the goods and the sub-container, and writes the binding relationship and the sub-container password in the electronic tag of the sub-container. And uploading the electronic tag information of the sub-turnover box and the confirmed delivery information to the cloud. And the cargo supervision module at the cloud records the information into the logistics information of the cargo.
And step S84a, the express delivery robot arrives at the docking point according to the planned route, and the goods are transferred to the next-level logistics chain. After the express robot uploads the information of the shipment determined by the user, the delivery information including the docking location, the identity information of the freight device docked with the express robot and the planned route is obtained through cloud computing, and the delivery information is sent to the express robot. And the express delivery robot arrives at the docking point according to the planned route. When the freight device arrives, the front cover of the container is opened by the express robot, the AGV in the freight device enters the container of the express robot, and the female turnover box is jacked up and transported back to the freight device. After the mother turnover box is carried away, the express robot removes the identity binding relationship between the express robot and the mother turnover box and uploads the identity binding relationship to the cloud, so that the goods taking task is completed, and the butt joint and delivery are completed. And the cloud end records the change information of the identity binding information into the logistics information of the goods.
And after the freight device receives the mother turnover box, establishing the identity binding relationship between the freight device and the mother turnover box.

The goods receiving user can interact with the express cabinet 10 through the client, after the identity is confirmed mutually, the sorting device in the express cabinet 10 sorts the child turnover box 7 containing the goods of the user into the cabinet mother turnover box 2, the child turnover box is carried to the user interaction storage location unit 1 by the AGV3, and the corresponding cabinet door 112 is opened. The user can know the password for opening the sub-turnover box 7 according to the information received by the mobile phone client, and open the sub-turnover box 7 to take away the goods at the prompt of the mobile phone client, such as video demonstration and the like. After the user returns the child container to the parent container for the cabinet and finishes taking the goods, the cabinet door 112 is closed.
When the user receives and delivers goods by self, the express cabinet is opened by a special cabinet door 112, of course, a cabinet door 111 when being butted with the express robot 8 or other goods delivery devices can be adopted, the main turnover box 2 is delivered out of the cabinet body through a lifting butt joint plate 122, if the user takes goods, the corresponding sub turnover box 7 with the goods is delivered out, and if the user delivers goods, the corresponding required sub turnover box 7 is delivered out.
Scene six: the user interacts with the unmanned aerial vehicle to take and deliver goods
The user may choose to pick up or receive goods from the drone when placing an order. When getting goods, unmanned aerial vehicle carries the sub-turnover case that corresponds the specification and reaches user's department, and the user puts the goods into sub-turnover case according to the instruction, like speech equipment in the unmanned aerial vehicle or demonstration video, the word explanation of customer service client side etc.. Unmanned aerial vehicle is provided with weighing transducer, and after the user finished packing, the charge of weighing, after the user paid, the flow of getting goods was ended, and this goods gets into logistics system. When the unmanned aerial vehicle dispatches goods, the interaction process is similar to that of the user and is not repeated here.
Scene seven: user interaction with a minivan
In this embodiment, the user may also interact with a pickup truck, driven or unmanned by the courier, to deliver or receive goods. When the mini-truck is unmanned, the mini-truck is provided with the interaction equipment, specifically, the interaction equipment of the express robot can be referred to, and the process is similar to the interaction process of the express robot and is not repeated.
When goods enter a logistics system through terminal logistics equipment such as an express robot, an unmanned aerial vehicle, an express cabinet or a mini-truck, the goods are transmitted in different freight devices. According to the types of the two freight devices during the transfer, the following docking scenarios are included:
A first docking scene: express delivery robot and express delivery cabinet butt joint
The express delivery robot can obtain the empty case with the purpose of express delivery cabinet butt joint, or will fail to deliver the goods of receiving goods user department and temporarily store in the express delivery cabinet, or take out the goods that need the delivery from the express delivery cabinet. Taking the empty box as an example, the docking process of the express robot and the express cabinet is described as follows:
when the express delivery robot 8 does not have a suitable sub-container at present, the express delivery robot can be obtained from a nearby express delivery cabinet, and the method specifically includes the following steps shown in fig. 77:
step S80b, the cloud system queries the express delivery cabinets and the traveling freight devices within the traveling range of the express delivery robot 8, and determines the positions where the express delivery robot 8 can acquire the required sub-transfer boxes according to the shortest acquisition time principle, in this embodiment, for example, the express delivery cabinet 10.
Step S81b, the cloud system sends a message for acquiring the child and parent transfer cases to the express robot 8 and the determined express cabinet 10, where the information received by the express robot 8 includes the position of the express cabinet 10 and may also include a planned travel route. The information received by the express delivery cabinet 10 includes the identity of the sub-containers and the identity of the express delivery robot, wherein one or more sub-containers are required according to the goods taking requirement.
Step S82b, the express delivery robot 8 moves to the location of the express delivery cabinet 10 according to the planned route, and meanwhile, according to the received message, the express delivery cabinet 10 sorts the required sub-containers into a parent container with the cooperation of the AGV3 by its internal sorting device, and establishes the identity binding relationship between the parent container and the sub-containers.
In step S83b, after the express delivery robot 8 arrives at the position of the express delivery cabinet 10, the identity of the express delivery robot and the express delivery cabinet 10 is mutually confirmed. As shown in fig. 78A.
In step S84b, after the two parties determine the identities, the express delivery cabinet 10 opens the cabinet door, puts down the docking plate 122, drives the slide rail 121 to lower the docking plate 122, and at the same time, the express delivery robot 8 opens the front cover of the container of the express delivery cabinet to prepare for docking. As shown in fig. 78B.
Step S85b, the express robot 8 moves forward to make the docking plate 122 enter the bottom of the base, and when the lift sensor is triggered, it indicates that the express robot 8 and the docking plate 122 are correctly docked, the slide rail 121 is driven to lift the express robot 8 together until the signal sent by the positioning sensor is received, which indicates that the driving surface of the moving space in the container of the express robot 8 is correctly docked with the driving surface on the lifting platform 42. As shown in fig. 78C. Wherein, the lifting sensor can be arranged at a proper position under the base of the express robot 8, and also can be arranged at a proper position of the butt plate 122. The positioning sensor may be provided at a suitable position of the docking plate 122 or the elevating platform 42.
In step S86b, the AGV3 inside the courier cabinet 10 transports the parent container with the child container already placed therein to the container of the courier robot 8, and returns the parent container to the courier cabinet 10. If there is a mother turnover case inside the express delivery robot 8, the AGV3 inside the express delivery cabinet 10 transports the mother turnover case inside the express delivery robot 8 to the express delivery cabinet 10, and then transports the child turnover cases required by the express delivery robot 8 together with the mother turnover case to the packing box of the express delivery robot 8.
In step S87b, the express delivery cabinet 10 drives the slide rail 121 to descend together with the express delivery robot 8.
In step S88b, the express delivery cabinet 10 is separated from the express delivery robot 8. After the express robot 8 lands, it retreats and leaves the docking plate 122, and then closes the front cover, and at the same time, the express cabinet 10 retracts the docking plate 122 and rises to a certain height, and the cabinet door 111 is closed.
At this time, the express robot 8 successfully obtains the required container from the express cabinet 10.
When the express delivery robot delivers goods and cannot deliver the goods to a goods receiving user, or the goods are stored in the express delivery cabinet. When the express robot stores the goods to be delivered together with the mother turnover box into the express cabinet, the binding change information of the mother turnover box is sent to the cloud management system, and the delivery task is completed. The cloud management system informs the receiver of goods taking in a telephone, a short message or a mail mode and the like. The process is similar to the process of emptying the box and is not described in detail herein. Similarly, the express delivery robot also can get the goods that need the delivery to the express delivery cabinet according to the instruction in high in the clouds, specifically with get the process of empty case similar, no longer give unnecessary details here.
A second docking scenario: express delivery robot and mini truck butt joint
Express delivery robot can transmit the goods of collecting from the user for minivan, also can receive the goods that need the delivery from minivan.
As shown in fig. 82A-82C, the docking of the mini-truck and the express delivery robot in this embodiment is schematically illustrated. When the mini-truck 9a is docked with the express robot 8, the door 94 is opened, and when the lifting support 962 of the lifting docking device is lowered to a preset position along the lifting rail 961, the docking plate 963 is opened. As shown in fig. 82A. The express robot 8 moves forwards, so that the butt joint plate 963 extends to the bottom of a container base of the express robot 8, after the position of the butt joint plate 963 is determined with the position of the container base, the lifting support 962 is controlled to ascend to a preset position along the lifting track 961, and the ascending is stopped after the running surface of the object moving space of the butt joint plate 963 of the container of the express robot 8 is in butt joint with the running surface of the bottom of the container position unit in the three-dimensional warehouse. At this time, the AGV3 inside the mini-truck 9a enters the container of the express robot 8 to transport the parent turnover box inside the mini-truck 9a to the mini-truck 9a, or transport the corresponding parent turnover box in the mini-truck 9a to the container of the express robot 8 as required.
A third docking scenario: express delivery robot and urban area circulation freight train butt joint
When conditions such as proper place and time conditions allow, the express delivery robot can also transfer goods taken and received by the user to the urban circulating truck and receive goods to be delivered from the urban circulating truck. This process is similar to docking of a mini-truck and will not be repeated here.
Similarly, the express delivery robot may also interface with an intercity freight device, such as a long or short haul truck, train, marine ship, etc. that is resting midway, as conditions such as appropriate location and time conditions permit.
As terminal logistics equipment, unmanned aerial vehicle can divide into large-scale unmanned aerial vehicle and unmanned aerial vehicle, and unmanned aerial vehicle only transports a sub-turnover case at every turn, a goods promptly. And large-scale unmanned aerial vehicle is inside to have a plurality of storehouse position units, can deposit a plurality of sub-turnover casees.
And C, docking a scene IV: unmanned aerial vehicle and express delivery cabinet butt joint
Unmanned aerial vehicle can deposit the goods of collecting from the user in the express delivery cabinet, or obtain the goods that need be dispatched from the express delivery cabinet.
Unmanned aerial vehicle is after collecting the goods from the user, according to high in the clouds calculation, can hand over the goods to other logistics equipment, like express delivery cabinet, minivan, urban area circulation freight train etc.. In this embodiment, the unmanned aerial vehicle deposits the goods to be delivered into the cabinet 10, or takes the goods to be taken out from the cabinet. When unmanned aerial vehicle reachd and pass the cabinet 10 sky soon, with express delivery cabinet 10 communication, after confirming the identity each other, apron 113 at the unmanned quick-witted kneck in top is opened to express delivery cabinet 10. If the user deposits goods, then the elevating platform of the in-cabinet elevating system takes the mother turnover box 2 to move upwards, and reaches the unmanned aerial vehicle interface. The unmanned aerial vehicle puts down the child turnover box 7 with the goods into the parent turnover box 2. When the unmanned aerial vehicle gets goods, the elevating platform takes the mother turnover box 2 with the built-in son turnover box 7 to move upwards and reach the unmanned aerial vehicle interface. Unmanned aerial vehicle snatchs sub-turnover case 7 from female turnover case 2. After finishing interacting with unmanned aerial vehicle, closing apron 113, the elevating platform takes female turnover case 2 to descend. Or, the cloud calculates that the unmanned aerial vehicle can send the goods in the express delivery cabinet to the goods receiving user, and the interaction process of the unmanned aerial vehicle and the express delivery cabinet is similar to the above process, and the description is not repeated here.
A fifth docking scene: butt joint of small unmanned aerial vehicle and fixed position warehouse

In this embodiment, the fixed-position warehouse (or referred to as a first stereoscopic warehouse) 100 is provided with an unmanned aerial vehicle interface 106 at the top thereof, in addition to the door 105, and the interface corresponds to one or more warehouse location units. When the small-sized unmanned aerial vehicle is to place the sub-containers 7 in the first stereoscopic warehouse 100, the first stereoscopic warehouse 100 opens the cover plate at the interface to expose the corresponding storage location unit thereunder. The drone may hover over the interface or rest on the interface by resting on the interface perimeter detents 107 via a stand. The fixed position is good, the small unmanned aerial vehicle puts the sub-turnover box into the storage position unit at the interface through the mechanical gripper and the like, and meanwhile, the identity binding relationship between the sub-turnover box and the unmanned aerial vehicle is removed. If the goods in the first stereoscopic warehouse 100 are to be transferred to the small unmanned aerial vehicle, the sub-turnover box needing to be carried by the small unmanned aerial vehicle is placed in the storage position unit at the interface, the sub-turnover box is identified by the small unmanned aerial vehicle through an RFID reader-writer and the like, the sub-turnover box is grabbed and taken away through a mechanical gripper and the like, meanwhile, the identity binding relationship between the sub-turnover box and the storage position unit is removed, and the identity binding relationship between the sub-turnover box and the unmanned aerial vehicle is established.
A docking scene six: docking of large unmanned aerial vehicle with fixed position warehouse
The large unmanned aerial vehicle is provided with a storage space similar to a stereoscopic warehouse, and the large unmanned aerial vehicle comprises a lift. Docking to the ground, or other stereoscopic warehouse, includes two ways.
First, docking is performed through the drone interface 106 in fig. 86. For example, a large drone may hover over the interface, or may be parked over the interface by a cradle resting on interface perimeter detents 107. After the position is determined, the large unmanned aerial vehicle puts down the elevator to be in butt joint with the interface, so that the goods are delivered and stored and exchanged.
Secondly, the large unmanned aerial vehicle hovers or falls on the ground on the side face of the stereoscopic warehouse, and is in butt joint with the stereoscopic warehouse through a butt joint plate or a butt joint pipeline, so that the goods are delivered and stored and exchanged.
A docking scene seven: unmanned aerial vehicle interacting with a freight device
Unmanned aerial vehicle also can be mutual with freight devices such as minivan, urban area circulation freight train, deposits or takes out the goods. Minivan, urban circulation freight train can set up the unmanned aerial vehicle interface, unmanned aerial vehicle interface in express delivery cabinet or the fixed position warehouse for example. Different with the interaction of express delivery cabinet, fixed position warehouse is that unmanned aerial vehicle when interactive with mobilizable logistics equipment such as minivan, urban area circulation freight train, mobilizable freight transportation device need not stop, when two keep the same speed, can deposit the sub-turnover case that unmanned aerial vehicle carried in the freight transportation device from the unmanned aerial vehicle interface, perhaps extract the goods from the freight transportation device.
And eighth butt joint scene: dock of mini-truck with fixed position warehouse
Figure 83 is a schematic illustration of a mini-van interfacing with a fixed location warehouse, in accordance with one embodiment of the present invention. When the mini-truck 9a is docked in a fixed position warehouse (e.g., a courier cabinet), the mini-truck 9a is moved into position with its doors facing each other and the door 94 and door 111 are opened. The fixed position warehouse door 105 is opened and the lifting bracket 962 of the lifting docking device of the mini-van 9a carries the docking plate 963 up to a preset position along the lifting rail 961, and the docking plate 963 is opened. The wagon 9a adjusts the position and the damping air bag, so that the butt plate 963 is accurately butted with the lifting platform 42 or the warehouse location unit of the fixed-position warehouse. At this time, the AGV3 inside the mini truck 9a enters the fixed-position warehouse to transfer the parent turnover box containing the child turnover box to be delivered inside the mini truck 9a to the mini truck 9a, or transfer the child turnover box and the parent turnover box that need to be received by the user in the mini truck 9a by themselves to the fixed-position warehouse as needed.
A docking scenario nine: the mini-truck is butted with the urban circulating truck
Figure 84 is a schematic illustration of a pickup truck docking with a city recycling truck, in accordance with one embodiment of the present invention. Since the mini-truck 9a is a small freight device and the height thereof is smaller than that of the urban circulating truck 9b, the stereoscopic warehouse inside the mini-truck cannot be directly butted with the stereoscopic warehouse in the urban circulating truck 9 b. After the doors of the two are opened, the lifting bracket in the butt joint device in the mini-truck 9a is lifted, and the butt joint plate is put down, so that the butt joint plate is completely butted with the running surface of the bottom surface of the storage position unit in the urban circulating truck 9 b.
Ten docking scenes: mini-truck and mini-truck butt joint
Because the transport distance of the mini-truck is short, when goods are transferred, the goods can be transferred to other mini-trucks when the goods cannot be transferred to the circulating freight train in the urban area in time.
Eleventh docking scene: the urban circulating truck is butted with the urban circulating truck
Fig. 85 is a schematic illustration of the docking of two urban recycle trucks 9 b.

A docking scene twelve: urban circulating truck and fixed position warehouse
As with the docking of a mini-truck to a fixed-location warehouse, the description is not repeated here.
A docking scenario thirteen: the urban circulating truck is butted with other freight devices
The three-dimensional warehouse is arranged on other freight devices, such as freight trains, freight airplanes and marine freight ships, when the urban circulating trucks are butted with the urban circulating trucks, a mode of butting two urban circulating trucks in the eleventh scene can be adopted according to the situation of the site, and the urban circulating trucks drive the X-Y driving platform to move out the three-dimensional warehouse and directly butt with the three-dimensional warehouse in other freight devices. Alternatively, these freight devices open their docking plate 300 and use a lifting mechanism to raise or lower it into position for accurate docking with the urban recycle wagon. In this embodiment, it is needless to say that the two stereoscopic warehouses may be butted by a pipeline having a bottom surface serving as a butt plate, so that the cargos are not affected by weather or climate when entering or leaving the warehouse.
Positioning sensors are arranged on the various logistics warehouses or the butt-joint plates, and whether the butt-joint is accurate or not is determined according to the positioning sensors.
When the two logistics devices are in butt joint, the goods are delivered out of the warehouse, put in the warehouse and exchanged. The warehouse structure shown in fig. 87 is taken as an example to explain the cargo delivery, storage, and exchange processes.
Embodiment one of cargo warehousing process
Fig. 87 is a schematic view of the docking of the stereoscopic warehouse with the shipping apparatus according to one embodiment of the present invention. Taking fig. 87 as an example, the cargo warehousing process will be described, where in fig. 87, the first stereoscopic warehouse 100 is a fixed-position warehouse, the second stereoscopic warehouse 200 is a stereoscopic warehouse in one cargo device, and a vehicle is not shown in fig. 87. As shown in fig. 88, the cargo warehousing process includes the following steps:
In step S9101, the cargo device travels to the side of the first stereoscopic warehouse 100, and both sides open the doors. The first stereoscopic warehouse 100 may be a fixed logistics warehouse.
Step S9102, the cargo device is docked with the first stereoscopic warehouse 100. As shown in fig. 87, the storage space unit 20 inside the small-sized second stereoscopic warehouse 200 in the cargo device has the same specification as the storage space unit 10 in the first stereoscopic warehouse 100. When the doors 105, 205 of both are open, the second stereoscopic warehouse 200 in the freight device can be directly docked door-to-door with the fixed first stereoscopic warehouse 100, as conditions permit. For example, by adjusting the angle of the freight device to be parallel and adjacent to the fixed first stereoscopic warehouse 100 and then adjusting the height and level of the second stereoscopic warehouse 200 in the freight device, in one embodiment, by adjusting the shock-absorbing air bags mounted on the vehicle, for example, adjusting the air pressure of each air bag, the level can be conveniently and quickly adjusted, so that the door 205 of the second stereoscopic warehouse 200 is completely butted with the door 105 of the fixed first stereoscopic warehouse 100. In addition, if the door 105 in the fixed first stereoscopic warehouse 100 is large, the door 205 of the second stereoscopic warehouse 200 is small, and the door 105 of the first stereoscopic warehouse 100 is large, it is possible to reveal multiple rows and multiple layers of bay units when it is opened. When the small-sized second stereoscopic warehouse 200 in the cargo device is butted, the second stereoscopic warehouse can be butted at any row and any layer.
And triggering the positioning sensors when the two stereoscopic warehouses are completely butted, indicating that the butting is completed after the local modules in the stereoscopic warehouses receive signals of the positioning sensors, and sending the information of completing the butting of the stereoscopic warehouses to the cloud logistics control module through the communication module. And the cloud logistics control module sends a transportation instruction to the AGV to carry the goods. And determining the number of the AGVs for conveying according to the number of the warehousing storage devices of the second stereoscopic warehouse 200 in the freight device, the number of the storage position units of the butt joint surfaces and the number of the currently available AGVs. In the present embodiment, it is assumed that only one parent container in the transport apparatus is stored in the first stereoscopic warehouse 100, and thus only one AGV is required. When the AGV is determined, an idle AGV is selected first, and when the AGV does not exist, the task of the AGV which is working is interrupted, so that the AGV carries the warehousing storage device.
Step S9103, determining whether there is an available AGV in the two warehouses, and if there is an available AGV230 in the second stereoscopic warehouse 200 or an available AGV130 in the first stereoscopic warehouse 100, in step S9104, the cloud logistics control module sends a transport instruction to the available AGV23 or the AGV 130. And then step S9108 is executed.
If there is no AGV in both warehouses, it is determined at step S9105 whether there is a spare AGV, such as one equipped inside the first stereoscopic warehouse 100 or in the freight device.
If there is a spare AGV, a transport instruction is sent to the spare AGV at step S9106, and then step S9018 is executed. If there is no spare AGV, the task of one AGV in the first stereoscopic warehouse 100 is interrupted and a transport instruction is sent thereto in step S9107.
In step S9108, the transporting AGV enters the storage unit 20 of the mother turnover box 220 to be transported. If the transporting AGV is the AGV130 in the first stereoscopic warehouse 100, since the floors of the bay units of the two warehouses are butted and communicated with each other after the two warehouse doors are butted against each other, the AGV130 can travel to the bay unit 20 in the second stereoscopic warehouse 200.
Step S9109, the AGV is carried to jack up the mother turnover box 220, the RFID information of the mother turnover box 220 is read, the bound storage location unit number is changed into a transportation state, and the RFID information of the mother turnover box 220 is sent to the cloud logistics control module.
In step S9110, the transporting AGV pushes the parent container 220 to enter one of the storage units in the first stereoscopic warehouse 100. Since only one parent turnover box is put in storage at this time, the parent turnover box is only carried into any one of the free storage space units in the first stereoscopic warehouse 100. If a plurality of mother turnover boxes are put in storage, the placement positions and the sequence of the mother turnover boxes need to be determined according to the number of the mother turnover boxes, for example, the mother turnover box needing to be carried firstly is put into a storage position unit far away from the bin gate 105, and the storage position unit near the bin gate 105 is reserved for the mother turnover boxes which are put in storage subsequently. If a plurality of transporting AGVs and a plurality of parent turnover boxes which are put in storage exist, the cloud can also calculate the walking route and the mutual matching mode when the AGVs are transported, the transporting scheme which consumes the shortest time for transporting is obtained, and a plurality of AGVs are controlled to complete the storage tasks of the parent turnover boxes according to the scheme.
Step S9111, the transport AGV reads the RFID information of the storage unit and acquires a serial number.
Step S9112, when the transport AGV releases the mother turnover box 220 to the stock position unit, the serial number of the stock position unit is written into the RFID information of the mother turnover box 220, the binding of the mother turnover box 220 and the stock position unit is completed, and the rewritten RFID information of the mother turnover box 220 is sent to the cloud logistics control module.
Step S9113, determine whether the transporting AGV is an AGV in the first stereoscopic warehouse 100, if so, wait to receive a new task in step S9114. If not, it is determined in step S9115 whether the transporting AGV is a standby AGV, and if so, it returns to the original position in step S9116. If not, it is explained that the transporting AGV is an AGV in the cargo conveyance device, the AGV returns to the cargo conveyance device in step S9117.
And S9118, closing the doors of the two warehouse parts to finish warehousing the goods. If the butt joint plate exists, the butt joint plate is withdrawn firstly, and then the bin door is closed.
According to the process, the AGV can be flexibly selected according to the current condition during warehousing, the final purpose is to finish warehousing of the goods as soon as possible, and the current other tasks are not interfered as much as possible when the purpose is achieved.
Second embodiment of cargo warehousing process
When a plurality of mother turnover boxes need to be put in storage, the method further comprises the step of determining the number of the transporting AGVs capable of being used for transporting. Namely, the cloud logistics control module determines the number of AGV capable of being used for carrying according to the current task amount of the two stereoscopic warehouses. When no goods are delivered to and stored in the three-dimensional AGV, the task of the three-dimensional AGV is to match the sorting device 6 to sort the goods in the three-dimensional warehouse in corresponding grades. Specifically, the cloud logistics control module controls the AGV and the sorting machine device 6 in the three-dimensional warehouse to sort the next goods out of the warehouse according to the flow direction of the next goods out of the warehouse. And the AGV carries the target parent turnover box to a sorting robot and sorts the target parent turnover box by the sorting robot. After the sorting is completed, the AGV transports the sorted mother turnover boxes which are discharged from the warehouse next time to the area near the warehouse door or the designated area. For the freight device, after the freight device is docked with the first stereoscopic warehouse 100 to transfer goods, the next place is needed to transfer the goods, and the AGV and the sorting robot inside the freight device need to sort the goods to be unloaded next time.
The cloud logistics control module determines available AGV data for the current transportation according to the time (such as the delivery time) required for next delivery of the goods in the first stereoscopic warehouse 100 and the sorting time required for delivery of the goods. Similarly, the cloud logistics control module determines the number of the AGV available for the transportation according to the transportation time of the freight device on the road when the freight device transfers the goods to the next butt joint place and the sorting time of the goods to be transferred in the sorting mode.
In addition, spare AGVs are usually reserved in the fixed warehouses to prevent the rapid delivery of the goods from being completed due to the excessive amount of tasks in each warehouse. Thus, the backup AGVs may also be included in the statistics of available AGVs, resulting in a total number of available AGVs.
After the number of the available AGVs is determined, the cloud logistics control module determines the single maximum conveying amount according to the current warehousing amount, the corresponding warehouse location unit number of the butt joint face after the warehouse door is opened, and the number of the available transporting AGVs so as to finish warehousing of the goods with the maximum efficiency. As shown in fig. 87, when the first stereoscopic warehouse 100 and the second stereoscopic warehouse 200 are butted by using the door-to-door method, the butting surface has two rows of storage location units, namely, two upper and lower layers and two left and right rows, so that 4 warehousing mother turnover boxes can be transported at a time according to the number of the storage location units of the butting surface. And then, combining the current total warehousing quantity and the number of available AGVs, for example, the current total warehousing quantity is 10, the first stereoscopic warehouse 100 has 4 AGVs, and the second stereoscopic warehouse 200 of the freight device has 2 AGVs, so that there are 6 available AGVs in total, and thus, the single maximum transportation quantity can be 4 warehousing mother turnover boxes.
Before the transportation starts, the cloud logistics control module sends a list of the warehousing mother turnover boxes in the second stereoscopic warehouse 200, which need to be transported into the first stereoscopic warehouse 100, to each available AGV. And the warehousing mother turnover box list records the identity information and the state of each warehousing mother turnover box. As shown in table 2 below:
Table 2: inventory of warehousing mother turnover box
Identity tag Status of state Total weight of goods
A-100-201-300001 N (non-transport) xxxg
A-100-201-300002 Moving (Moving) xxxxg
A-100-201-300003 Y (carried) xxxg
…… …… ……
And a warehousing mother turnover box list is stored in each transporting AGV. When the AGV enters the storage space, the warehousing mother turnover box to be moved out is identified according to the warehousing mother turnover box list, when the warehousing mother turnover box is carried, a message is sent to the cloud logistics control module, and the cloud logistics control module updates the warehousing mother turnover box list in each available AGV.
Fig. 89 is a schematic flow chart of the AGV transporting the parent turnover box according to an embodiment of the present invention;
and step S9210, the cloud logistics control module sends a warehousing mother turnover box list to the AGV.
And step S9200, the transporting AGV receives the warehousing mother turnover box list, stores the warehousing mother turnover box list locally, and updates and maintains the warehousing mother turnover box list according to the updating message sent by the cloud logistics control module.
And step S9201, the AGV is carried to enter a stereoscopic warehouse. The handling AGV is the AGV130 entering the first stereoscopic warehouse 100, and may also be the AGV230 in the second stereoscopic warehouse 200, or a backup AGV.
Step S9202, the transporting AGV reads the identity tag of one parent turnover box 220 that the transporting AGV encounters, and obtains the identity information of the parent turnover box 220 from the identity tag.
Step S9203, it is determined whether the parent container 220 is in the warehousing parent container list and whether the status is not transported, and if yes, step S9204 is executed. If not, returning to the step S9202 to read the identity label of another mother turnover box.
In step S9204, the parent container 220 is ejected, and the information of the location unit in the label information of the parent container 220 is rewritten to the moving state, that is, the binding relationship between the parent container 220 and the second location unit currently described above is released.
Step S9205, the transporting AGV sends the modified identity label information of the mother turnover box 220 back to the cloud logistics control module, namely sends the unbinding message to the cloud logistics control module.
And step S9211, the cloud logistics control module records the current state of the warehousing mother turnover box and updates the warehousing mother turnover box list.
And step S9212, the cloud logistics control module sends the updated warehousing mother turnover box list to all available AGV.
In step S9206, the transporting AGV pushes the parent turnover box 220 to return to the first stereoscopic warehouse 100, and places the first stereoscopic warehouse in a first warehouse location unit.
Step S9207, the transporting AGV writes the identity information of the first storage location unit into the identity label information of the mother turnover box 220, and binds the identity information of the mother turnover box 220 and the first storage location unit.
Step S9208, the transporting AGV sends the bound identity information of the mother turnover box 220 to a cloud logistics control module.
Step S9213, the cloud logistics control module records the new binding relationship of the parent turnover box 220, and updates the warehousing parent turnover box list.
And step S9214, the cloud logistics control module sends the updated warehousing mother turnover box list to all available AGV.
According to the process, in the warehousing process, a constantly-changing warehousing mother turnover box list for recording the state of the warehousing mother turnover box is maintained in all the transporting AGV, so that each transporting AGV can be ensured to find the correct warehousing mother turnover box.
Regarding the position of the second storage location unit for storing the warehousing mother turnover box in the first stereoscopic warehouse 100, generally, under the control of the cloud logistics control module, the first stereoscopic warehouse 100 is close to the warehouse door, and the area for receiving goods is kept in an idle state, so that the warehousing mother turnover box can be quickly received. In one embodiment, the transporting AGVs randomly place the warehoused mother totes at the innermost end of the free area to free the area at the outer end for the mother totes that are warehoused later. For example, after an AGV enters the first stereoscopic warehouse 100, it is queried whether there are spare warehouse location units around its current location, and when there is a parent container in the current warehouse location unit, it moves to the left or right, and places the parent container in the warehouse at the end of the current direction. And then returns to the second three-dimensional warehouse 200 of the freight device to carry the next warehousing mother turnover box. Each transport AGV can all place the female turnover case of warehouse entry according to same placing principle.
In another embodiment, the cloud logistics control module may divide a warehousing area for the warehousing operation according to the number of the warehousing mother containers, and the positions and the number of the idle warehousing bit units in the first stereoscopic warehouse 100. And the transporting AGV sequentially places the warehousing mother turnover boxes in the warehousing area.
Cargo delivery process embodiment
The invention also provides a process when goods are to be delivered out of the warehouse. As shown in fig. 90.
In step S9300, when the freight device arrives, the freight device travels to the side of the first stereoscopic warehouse 100, and both sides open the doors.
In step S9301, the cargo device is docked with the first stereoscopic warehouse 100. The butt joint is the same as the butt joint in the warehouse-in process, and can adopt door-to-door butt joint or one or more butt joint plates and butt joint pipelines for butt joint.
In step S9302, available AGVs are determined.
Step S9303, the transporting AGV transports the ex-warehouse parent turnover box 120, and releases the binding relationship between the ex-warehouse parent turnover box and the current first warehouse location unit 10. And sending the unbinding message to a cloud logistics control module.
In step S9304, the transporting AGV transports the outgoing parent turnover box to one second storage location unit 20 in the second stereoscopic warehouse 200 in the cargo transportation device.
Step S9305, establishing a binding relationship between the ex-warehouse parent transport container and the second warehouse location unit 20, and sending the binding relationship to the logistics control module at the cloud.
The ex-warehouse process and the related details are similar to the in-warehouse process, and the description thereof is not repeated.
When goods need to be exchanged between two stereoscopic warehouses, for example, a part of goods in the first stereoscopic warehouse needs to be transported to the second stereoscopic warehouse, and a part of goods in the second stereoscopic warehouse needs to be transported to the first stereoscopic warehouse at the same time, the warehousing and ex-warehouse processes are included, and the warehousing and ex-warehouse processes are performed at the same time. In this embodiment, the cloud logistics control module maintains two tables: warehousing lists and ex-warehouse lists. And after determining the available AGVs through calculation, sending the two tables to the available AGVs. And driving available AGVs in the two libraries to carry the ex-warehouse mother turnover box of the library to the opposite side, carrying the ex-warehouse mother turnover box from the opposite side back to the in-warehouse mother turnover box, and maintaining the two tables in real time by the cloud logistics control module in the carrying process.
In order to improve the goods exchange efficiency, the positions of the goods in the warehouse and the carrying routes of the AGV in the exchange process can be planned.
First embodiment of cargo handling process between stereoscopic warehouses
Fig. 91 is a flow chart of a parent container being transported to a designated stock location unit according to another embodiment of the present invention. In this embodiment, the cloud logistics control module determines, for each available AGV, the parent container taken by the AGV and the storage location unit to be placed in real time according to the current positions of the first and second parent containers and the first and second storage location units. Therefore, in this embodiment, the cloud logistics control module maintains the parent turnover box lists of the first and second warehouses and the exit and storage location lists in real time, and according to the exit and storage conditions of the two current warehouses, firstly, sends the identity information of the parent turnover box to be transported to each AGV, when the AGV transports the parent turnover box from the first stereoscopic warehouse to the second stereoscopic warehouse, the cloud logistics control module determines the storage location unit to be placed according to the current storage location unit of the first stereoscopic warehouse and the transport busy condition, and sends the identity information of the storage location unit to the AGV, and the AGV places the parent turnover box to the specified storage location unit according to the identity information of the specified storage location unit. In order to avoid redundant description, the steps of unbinding and binding the identity relationship between the parent container and the library location unit and updating the list are omitted in the following description. In this embodiment, the process of transporting a parent container to a designated storage location unit includes the following steps:
Step 9401, the cloud logistics control module sends identity information of a first parent turnover box to be carried to a first AGV in the first stereoscopic warehouse. Wherein, the first mother turnover box is a mother turnover box which is closest to the first AGV.
And step 9402, the first AGV transports the first mother turnover box to the second stereoscopic warehouse according to the received message.
And 9403, determining a placeable second storage location unit by the cloud logistics control module according to the state and the carrying condition of the current second storage location unit, and sending the information of the second storage location unit to the first AGV.
Step 9404, the first AGV places the first parent turnaround box into the designated second bay unit according to the received second bay unit information.
And repeating the steps until all the mother turnover boxes are transported.
Second embodiment of the process for exchanging goods among stereoscopic warehouses
Fig. 92 is a flowchart of the exchange of goods between warehouses according to one embodiment of the present invention. In this embodiment, two stereoscopic warehouse will be respectively warehouse door near region divide into the district of leaving warehouse and the district of warehousing, and the position list of leaving warehouse and the position list of entering warehouse that correspond are kept and maintained to high in the clouds logistics control module. In the present embodiment, the transport processes of AGVs in the first stereoscopic warehouse 100 and the second stereoscopic warehouse are the same, and here, a description will be given by taking one first AGV in one first stereoscopic warehouse 100 as an example, where the delivery parent turnaround box in the first stereoscopic warehouse 100 is referred to as a first parent turnaround box, and the delivery parent turnaround box in the second stereoscopic warehouse 200 is referred to as a second parent turnaround box.
And step S9500, the cloud logistics control module sends the first and second warehouse parent turnover box lists and the warehouse-out and warehouse-in position lists to all available AGVs.
In step S9501, each available AGV stores and maintains the plurality of manifests.
In step S9502, the first AGV transports one first parent turnover box in the first stereoscopic warehouse 100 to the second stereoscopic warehouse. Still including unbinding the relation of binding of first female turnover case and former first storehouse position unit to send it to high in the clouds logistics control module group, high in the clouds logistics control module group changes this first female turnover case state in first female turnover case manifest for the mobile state. And updating the first parent transfer box list in all the AGVs by adopting the updated information.
Step S9503, the first AGV identifies the second warehousing area of the second stereoscopic warehouse, for example, reads the identity tag of the free warehouse location unit in the warehouse, and compares the locally stored second warehousing location list of the second stereoscopic warehouse, thereby finding the second warehousing area.
And S9504, placing the first mother turnover box into a second storage location unit in a second storage area, binding the identity relationship between the first mother turnover box and the second storage location unit, and sending the identity relationship to the cloud logistics control module. And the cloud logistics control module updates the first mother turnover box list and the second warehousing location list according to the information, and updates the local lists of all the AGVs by adopting the updated information.
In step S9505, the first AGV determines whether or not there is a second parent container that has not been transported, and if so, performs step S9507, and if the second parent container has been transported, returns to the first stereoscopic warehouse in step S9506.
In step S9507, a second ex-warehouse area is identified.
Step S9508, the first AGV transports the second parent turnover box from the second delivery area to the first storage area of the first stereoscopic warehouse. When the second mother turnover box is moved away from the second storage position unit, the binding relationship between the second mother turnover box and the second storage position unit is unbound, and when the second mother turnover box is placed in the first storage position unit of the first storage area, the identity relationship between the second mother turnover box and the first storage position unit is bound. The cloud logistics control module updates the change information brought by the unbinding and binding relations and updates a plurality of lists in all the AGVs.
And step S9509, the first AGV judges whether the first mother turnover box is not conveyed completely, if so, the step S9502 is returned, and if the first mother turnover box is conveyed completely, the goods exchange process is ended.
In this embodiment, through dividing warehouse entry area and warehouse exit area, can make the AGV clear at the transport, when placing female turnover case target.
In the above embodiments, the cloud logistics control module is adopted, but it should be understood by those skilled in the art that a local management system may also be included, that is, each stereoscopic warehouse may include a local management system, and data, messages and the like may be exchanged through the communication module, so that the processes in the above embodiments may also be completed.
Sorting during the transport of goods
The logistics system provided by the invention does not need a sorting center in a fixed place, does not need to unload goods from the transportation process to the sorting center for sorting and then continuously transporting, and places the sorting device into a stereoscopic warehouse of the goods transportation device for sorting in the goods transportation process. In one embodiment, as shown in fig. 93A to 93D, the stereoscopic warehouse goods sorting method includes:
and S620, determining the current sorting address information according to the logistics transportation information. For example, the logistics place where goods need to be sorted out when the goods are next docked is determined according to the current position of the stereoscopic warehouse and the logistics direction of the freight device docked with the stereoscopic warehouse, and the logistics place can be geographical position information or an administrative area determined according to the geographical position information.
And step S621, analyzing the address information of each sub-turnover box in the stereoscopic warehouse and the mother turnover box where the sub-turnover box is located according to the sorting address information to determine a target mother turnover box and a target sub-turnover box. In this step, by analyzing the address information of the sub-containers and comparing the address information with the determined sorting address, a target sub-container to be sorted can be determined, and according to the binding relationship between the sub-container and the parent container, a target parent container (hereinafter referred to as a first target parent container) in which the target sub-container is located and a first storage location unit in which the target parent container is located can be determined, so that the distribution condition of the first target parent container in the warehouse is determined. And determining a second target parent turnover box for storing the sorted target child turnover boxes by inquiring the condition of the child turnover boxes built in the parent turnover box according to the specification information of the child turnover boxes. In one embodiment, some empty mother turnover boxes can be placed in the warehouse to be used as second target mother turnover boxes during sorting, so that the sorting efficiency can be improved. According to the binding relationship between the mother turnover box and the storage location unit, the position of the second storage location unit can be known after the second target mother turnover box is determined, so that the distribution condition of the second target mother turnover box in the warehouse is determined. In order to supervise the sorting process, the information is formed into a target sub-container for recording information related thereto, as shown in table 1.
Step S622, determining a corresponding sorting task for each sorting device and a corresponding carrying task for each transferring device according to the distribution information of the target parent turnover boxes in the warehouse, the distribution information of the sorting devices, and the number and position information of the transferring devices. In order to improve the sorting efficiency, a near principle is generally adopted, that is, a sorting device is used as a center, and a target parent turnover box nearby the sorting device is distributed to the sorting device. Or, considering that two target parent turnover boxes need to be transported corresponding to the sorting of one target child turnover box, calculating the time required for transporting the two target parent turnover boxes to each sorting device according to the positions of the two target parent turnover boxes and the positions of the sorting devices, and allocating the tasks of the sorted target child turnover boxes to the sorting device with the least required time. According to the method described above, each sorting device is assigned a respective sorting assignment. In one embodiment, each sorting device generates a sort list including the target child containers, the corresponding first target parent containers and the corresponding second target parent containers.
And after the first target mother turnover box, the second target mother turnover box and the corresponding sorting devices are determined, distributing corresponding carrying tasks for the object moving devices according to the distribution condition of the object moving devices. When the number of the transferring devices is small, the first target mother turnover box and the second target mother turnover box can be conveyed by one transferring device for two times. When the number of the article transferring devices is large, the first and second target parent transport containers may be transported by the two article transferring devices. After the first target mother turnover box and the second target mother turnover box are conveyed to the sorting units of the sorting device, the AGV can stop, wait for the sorting to be completed, and move the first target mother turnover box and the second target mother turnover box away from the sorting units, or move the first target mother turnover box and the second target mother turnover box to the sorting units of the sorting device to receive new conveying tasks. And when the first target parent turnover box and the second target parent turnover box are carried, the object moving device also executes establishment and release of the identity binding relationship between the parent turnover box and the storage location unit.
In step S623, the AGV transports the first and second target parent containers to the first and second sorting units of the sorting apparatus.
In step S624, the sorting device sorts the target sub-containers from the first target parent container to the second target parent container.
After the sorting is finished once, corresponding processing is carried out according to the conditions of the first target parent turnover box and the second target parent turnover box, for example, if the first target parent turnover box still has a target child turnover box, and the second target parent turnover box has a corresponding position, the sorting is continued. As shown in fig. 93B.
Step S625, determining whether there is any new target sub-container not sorted in the first target parent container, if yes, executing step S6251, and if not, executing step S626 in fig. 93C.
In step S6251, it is determined whether the second target parent turnover box has a position corresponding to the new target child turnover box, and if so, the process returns to step S624 to continue sorting in the two original first and second target parent turnover boxes. If not, step S6252 is performed.
In step S6252, it is determined whether or not the original second target parent container is already the target child container, and if so, in step S6253, the original second target parent container is transported to the delivery area, and then step S6254 is executed. If the original second target parent container is not all the target child containers, that is, if there are other non-target child containers, the second target parent container is updated in step S6254, that is, the original second target parent container is moved away, the new parent container having the new target child container position therein is moved as the second target parent container, and then step S624 is performed. And sorting between the original first target mother turnover box and the new second target mother turnover box.
If the first target parent turnover box is a new target child turnover box without unsorted objects, that is, the first target parent turnover box is sorted, in order to reduce the number of times of transportation and improve the sorting efficiency, the process shown in fig. 93C is further included.
In step S626, it is determined whether there is a new target child container in the original first target parent container, if not, step S627 is executed in fig. 93D, and if so, step S6261 is executed.
Step 6261, determining whether there is a corresponding new target child turnover box in the original second target parent turnover box, if yes, executing step 6265, if not, executing step 6262.
Step S6262, determining whether the original second target parent turnover box is the target child turnover box, if yes, in step S6263, transporting the original second target parent turnover box to the warehouse-out area, and then executing step S6264, if the original second target parent turnover box still has the non-target child turnover box, executing step S6264.
In step S6264, the second target parent container is updated, that is, the original second target parent container is removed, a new parent container having the new target child container therein is transported, and then step S6265 is performed.
Step S6265, the identities of the current first target parent turnover box and the new second target parent turnover box are changed, that is, the original outward sorted first target parent turnover box is converted into the second target parent turnover box for receiving the target child turnover box, the current parent turnover box with the target child turnover box is used as the first target parent turnover box for the outward sorted target child turnover box, and then step S624 is executed to sort.
In fig. 93D, the original first target parent container has neither the target child container nor the position for placing the target child container, and therefore, in step S627, it is determined whether there are any target child containers to be sorted, and if not, the sorting is completed, and the sorting process is ended. If yes, the situation of the current original second target parent container needs to be checked, that is, step S628 is executed.
In step S628, it is determined whether there is a new target sub-container in the original second target parent container, if yes, in step S6281, the first target parent container is updated, that is, the original sorted first target parent container is carried away, and then the parent container matched with the new target sub-container in the current second target parent container is carried away, and then step S624 is executed to sort. If the original second target parent turnover box has no position of the new target child turnover box, step S629 is executed.
Step S629 determines whether there is a new target child turnover box in the original second target parent turnover box, if not, step S6291 updates the current two first and second target parent turnover boxes, and then step S624 is executed for sorting. If the original second target parent turnover box has the new target child turnover box, step S630 is executed.
And step S630, replacing the original second target mother turnover box with the first target mother turnover box.
And step S631, transporting the original first target mother turnover box, transporting the new mother turnover box as a second target mother turnover box, and then executing step S624 to sort.
The sorting device is used for identifying whether the current primary turnover box of the first sorting unit is the first target primary turnover box to be sorted or not in the sorting process, and identifying and judging whether the current primary turnover box of the first sorting unit is the second target primary turnover box or not when the target secondary turnover box is placed into the current primary turnover box of the second sorting unit, so that the sorting error can be prevented.
The sorting device also needs to modify the binding relationship between the child turnover box and the parent turnover box in the sorting process, for example, when the target child turnover box is taken out from the first target parent turnover box, the binding relationship between the target child turnover box and the first target parent turnover box is removed, and when the target child turnover box is put into the second target parent turnover box, the binding relationship between the target child turnover box and the second target parent turnover box is established.
Before the second target parent turnover box filled with the target child turnover box is conveyed to the warehouse-out area, a storage unit list for storing the second target parent turnover box which is sorted is determined according to the distribution of the free warehouse position units in the warehouse. And preferentially determining the free warehouse bit units in the warehouse-out area as the storage warehouse bit units for storing the second target parent turnover boxes which are sorted. When the AGV carries a carrying task of a second target parent round having filled the target child round, the AGV carries the second target parent round to a designated storage unit. Since the goods are preferentially placed in the delivery area, the delivery of the goods can be quickly finished when the goods are in butt joint with other stereoscopic warehouses and freight devices.
The method of the present invention for mid-stream transfer type distribution is described in detail below with reference to specific examples.
Scene: beijing A women shengxian A shengxiang an china box of china, selected the special fast logistics level of aviation.Referring to fig. 94, the logistics flow path includes the following steps:
in step S1, a logistics order is generated. Comprising the steps shown in fig. 95:
step S11, the A lady generates a logistics order including the name, address and contact information of the receiver through a customer service client, such as APP or small program supported by a mobile phone; the name, address and contact of the shipper; logistics level (air express); size; and the customer service client generates a two-dimensional code according to the information such as the insurance price, the reserved delivery mode, the time and the like and sends the two-dimensional code to the server. This process took approximately 2 minutes.
And step S12, after receiving the two-dimensional code, the server analyzes the two-dimensional code to obtain order information, stores the order information into a database, and informs each logistics control module at the cloud.
And step S13, determining a related logistics control module according to the goods taking place.
Step S14, the logistics control module determines an express robot for picking up goods according to the location of picking up goods, the time for reserving picking up goods, the current traffic situation, the distribution and workload of the express robots in the area, for example, the number is R005569, determines the sub-containers according to the goods information in the order, that is, the identifiers of the sub-containers are determined, for example, a300x180x180, and generates a task of picking up goods to allocate to the determined express robot R005569.
And step S2, taking the goods. Comprising the steps shown in fig. 96:
in step S21, the express robot R005569 carries the specified sub-container according to the received information in the pick-up task, and arrives at the pick-up location L1 according to the specified route or the route calculated by its own geographic information system. Wherein, preferably, the express delivery robot R005569 informs A ladies 10 minutes before arrival and phone/short message after arrival.
Step S22, the shipper' S identity is verified and loaded. After the mobile phone and the identity of the lady A are verified, the top cover of the container is opened, the lady A is guided by voice or video to open the appointed sub container A300x180x, the porcelain which is simply wrapped is put in, and the container opening password is covered and set.
Step S23, weighing and charging. The express delivery robot R005569 calculates the cost according to the weighing information and informs the cost through voice and a display screen, and after the ladies A agree, the goods taking is completed through voice confirmation or clicking a confirmation key of the display screen. Express delivery robot R005569 will with A ms's interactive process whole journey video of getting goods upload to the high in the clouds, save in the database for fetch when the problem appears and look over. The express delivery robot R005569 takes about 3 minutes to take the goods in the whole course by interaction with the user. After the goods are taken, the goods enter the logistics system, and the goods delivery is started, namely 10 a.m.: 00.
At the moment, the child turnover box containing the A lady goods is located in a mother turnover box M500B700C100 in a container of an express robot R005569, the express robot R005569 establishes an identity binding relationship between the lady goods and the child turnover box A300x180x180, establishes an identity binding relationship between the child turnover box A300x180x180 and the mother turnover box M500B700C100, and associates an identity of the express robot R005569.
In the following cargo exchange process, after the child container a300x180x180 is separated from the parent container M500B700C100, the identity binding relationship between the child container a and the parent container is released, and the identity binding relationship between the child container a300x180x180 and the new parent container is established. When the freight device changes, the identity relationship between the parent turnover box and the freight device also needs to be bound again, and all the change messages are recorded in the identity tags of the child turnover boxes and are simultaneously uploaded to the cloud goods monitoring module. In the following process, changes to the relationship are not described again for the sake of simplifying the description.
And step S3, transporting goods. Specifically, the steps shown in FIGS. 97A-97B are included:
step S31, after the goods are taken, the cloud logistics control module determines the location L2 and the shipping device for the first time of goods docking according to the current location L1 of the express robot R005569 (which is the location of the goods issuing point, i.e., the location where the goods are taken in agreement with ladies a at this time), the logistics direction of the goods, the distribution of other shipping devices in the area, and the transportation direction. For example, it is determined that a minivan a0101 docks with a courier robot R005569. Because the user selects the air express, the logistics control module inquires the freight flight which is newly sent to the destination in the airport and determines the reasonable time for the arrival of the goods at the airport to board. In the subsequent determination of the cargo device, the airport direction and boarding time are used as determination information.
In step S32, the express delivery robot R005569 arrives at the docking designated location L2 according to a designated route or a self-calculated route, and merges with the minivan a 0101. For example, a distance of 0.5km, taking 10 minutes.
Step S33, the transfer device of the stereoscopic warehouse in the minivan A0101, such as an AGV, carries the mother turnover box in the express robot R005569 container to the stereoscopic warehouse of the minivan A0101. If the goods to be dispatched are in the mini-truck A0101, the parent turnover box to be dispatched is conveyed into the container of the express robot R005569. This process takes about 5 minutes. At this point, the pick-up task of the delivery robot R005569 is completed, and a new dispatch task is started. At this time, the express robot R005569 is an upper logistics chain and the minivan a0101 is a lower logistics chain in terms of the logistics direction.
Step S34, the cloud logistics control module determines the freight device (such as urban area circulating truck B011) and the docking location L3 (and the driving route) of the lower logistics chain docked with the mini truck A0101 according to the current position L2 of the mini truck A0101, the logistics direction and boarding time of the freight airport, the distribution conditions and the current transportation direction of other freight devices in the area, such as other mini trucks and urban area circulating trucks, and sends the information to the mini truck A0101 and the urban area circulating truck B011.
Step S35, the cloud sorting control module determines two vehicle sorting cargo lists according to cargo information and sorting addresses of stereoscopic warehouses inside the mini-truck A0101 and the urban circulating truck B011, and the two vehicle sorting cargo lists are respectively sent to the stereoscopic warehouse in the mini-truck A0101 and the stereoscopic warehouse in the urban circulating truck B011.
In step S36, the minivan a0101 and the urban area circulating van B011 travel to the docking point L3 according to the designated or self-calculated travel route, respectively. During the driving process, sorting devices in stereoscopic warehouses built in the minivan A0101 and the urban area circulating freight car B011 sort the sub-turnover boxes according to the received sorted goods list, so that goods needing to be exchanged are sorted out before meeting. For the goods just received for A lady, the sorting is primary sorting. Since there are other goods on the mini-truck a0101, depending on the direction of logistics, it may be necessary to transfer to the urban recycling truck B011 at the docking point L3, for which there is the possibility of primary sorting (e.g. goods transferred from other delivery robots) or secondary or tertiary sorting, e.g. goods transferred from other mini-trucks or more urban recycling trucks. For the micro-truck A0101, the distance of moving to the confluence point according to the cloud-end planned path is 2km, and the time is about 10 minutes.
In step S37, after the minivan a0101 and the urban area circulating van B011 dock at the docking point L3, they exchange their cargoes. It took about 5 minutes.
Step S38, the cloud logistics control module determines a driving route of the urban circulating truck B011 and goods needing to board at the airport according to the current position L3 of the urban circulating truck B011 and the airport position. In which, with reference to the cargo boarding time, it can be determined whether or not cargo can be exchanged with other cargo devices on the intermediate journey from the position L3 to the airport.
Step S39, the urban circulating truck B011 drives to the airport according to the planned route, and the sub-turnover boxes needing to be boarded are sorted in the driving process, which can be called zone-level sorting. If time is available, other cargo devices may be received on the road, such as cargo transported by a minivan or courier robot to an airport. The distance from location L3 and the airport was 40km, taking about 60 minutes.
Step S310, after the urban circulating truck B011 is in butt joint with the freight airplane, the mother turnover box is conveyed to the stereoscopic warehouse of the freight airplane by a moving device in the stereoscopic warehouse, such as an AGV, and the time is about 30 minutes.
Step S311, the freight airplane takes off from Beijing, and the sorting robot sorts the sub-turnover boxes in the market grade in the flying process, namely, sorts out the goods going to different cities, which is called market grade sorting.
Step S312, the cloud logistics control module determines a plurality of urban area circulating trucks to be docked according to the landing time of the airplane, the destination of the next takeoff of the airplane, and the direction of the goods transported in the airplane, wherein the urban area circulating trucks include urban area circulating truck B708 of the city to which the goods delivered by ladies a are going, plans routes for the urban area circulating trucks, and sends the routes to the corresponding urban area circulating trucks.
And step S313, the cargo airplane lands the Shenzhen airport for about 220 minutes (12: 00 takeoff → 15:40 landing), and is butted with a plurality of urban circulating trucks including an urban circulating truck B708 to exchange mother turnover boxes. It took about 30 minutes.
Step S314, the cloud customer service system informs Shenzhen A of the approximate receiving time through a telephone or a short message, and meanwhile, the cloud line planning module plans a delivery path. For example, according to the destination of the cargo, the distribution of the current urban cargo devices and the cargo flow direction thereof, the cargo device and the location L4, such as the mini-truck a5603, which are determined to be docked with the urban recycling truck B708 are determined.
In step S315, the urban circulating truck B708 performs zone-level sorting on the sub-turnaround boxes during the moving process. Meanwhile, the mini-truck A5603 performs zone-level sorting on the sub-turnover boxes in the moving process. Assuming location L4 is 40km from the airport, the time taken for urban recycle truck B708 to reach docking location L4 is 60 minutes.
In step S316, after the urban circulating truck B708 is docked with the mini truck a5603, the cargo exchange is performed. It took about 5 minutes.
In step S317, the cloud circuit planning module determines the express robot R110020 and the docking point L5 docked with the minivan a5603 according to the cargo destination and the distribution and operation conditions of the express robots in the region.
Step S318, the minivan a5603 moves to the docking location L5, and final sorting is performed during the movement, that is, the goods sent by ladies a are sorted out. The minivan a5603 reached the docking point L5, and traveled for 2km for 10 minutes.
Step S319, the mini-truck A5603 is converged with the express robot R110020, and the parent turnover box with the A lady goods placed therein is transferred to the express robot R110020. It took about 5 minutes. If the express robot R110020 also has goods to be transferred to the mini-truck A5603, the goods of the express robot R110020 are firstly carried to the mini-truck A5603, and then the main turnover box with the A lady goods is transferred to the express robot.
And step S4, dispatching. The cloud service system determines a delivery location of the goods according to the communication with mr. a, or the cloud service system determines a delivery location L6 according to the order address or the goods storage cabinet in the order address area. In this embodiment, the place designated by mr. a is taken as an example. Specifically, the steps shown in fig. 98 are included:
In step S41, the express delivery robot R110020 moves to the delivery location L6 according to the cloud plan or a route calculated by itself. For example, a distance of 1km, taking 30 minutes.
In step S42, the express robot R110020 calls/notifies mr a in the first 10 minutes and the last time of arrival. And when the customer arrives at the location L6, waiting for a preset time, if the preset time is exceeded, asking for the cloud customer service system, prolonging the waiting time or placing the customer service system in a nearby express cabinet (a small three-dimensional warehouse with the same specification) and uploading the change information to the customer service system. The customer service system informs the A of the delivery of the first-generation in the modes of telephone, short message or mail and the like.
And step S43, the Mr. A arrives within the longest waiting time, and the express robot R110020 automatically opens the cargo box cover after verifying the mobile phone and the identity of the Mr. A.
And step S44, the express robot R110020 voice guides Mr. A to open the sub-circulation box, take out the porcelain, cover the sub-circulation box after the porcelain is confirmed to be intact and click a confirmation key of a display screen, and the dispatching is finished. Express delivery robot R110020 is uploaded the cloud in the whole video with mr A's interactive process, and this process takes about 3 minutes.
Measured in the manner of this example, this logistics transportation spans over half of china, is about 2000 kilometers throughout, and takes only about 480 minutes (8 hours, excluding dispatch waiting time). If the shipment was at 10 am, it could be delivered at 18 pm. Compare in current logistics system, the transportation effect has promoted several times.
In this embodiment, the target cargo needs to move between two cities, and in this embodiment, a cargo airplane is selected, but railway transportation or long-distance truck transportation may also be selected. Because different freight devices have different time and cost, the system determines different logistics levels according to the freight devices, the time and the cost for the users to select. For example, the shortest time, but the highest cost, of the cargo plane can satisfy the users who have high time-consuming requirements, but not limited to the cost, and for most users, the time-consuming of the cargo is not important, so that the common level can be selected first, and the corresponding cargo device used in the logistics system may be rail transportation or long-distance truck transportation. Therefore, the invention can meet various user requirements.
In the above embodiment, during the transportation in step S3, the freight devices and docking points of each logistic chain level to be docked are calculated at the start of transportation, and then are continuously corrected during the real-time transportation to cope with the change caused by the emergency. For example, when the express robot finishes taking the goods, the route planning module in the cloud calculates various freight devices, transportation directions and current traffic conditions thereof from the location L1 where the express robot is located to the airport along the way according to the currently determined docking point-airport and the determined time of the target goods, so as to determine a plurality of docking locations and docking freight devices required from the location L1 where the express robot is located to the airport. After the docking is realized at one docking point, a plurality of docking points and docking freight devices required from the current point to the airport are calculated again, if the docking points and the docking freight devices are not consistent, the result of the last calculation is taken as the standard, namely the initial route scheme is corrected by the calculation.
The logistic chain in this example is briefly described as follows:
client → express robot → mini truck → urban area recycle truck → freight airplane → urban area recycle truck → mini truck → express robot → client.
In the above logistics chain, the docking condition of the multi-stage freight devices in the city is as follows: the first-level freight device express robot is in butt joint with the second-level freight device mini truck, and the second-level freight device mini truck is in butt joint with the third-level urban area circulating truck. However, this process is only an example, and the docking process may also be a process in which a first-level freight device and an express robot dock a third-level urban area circulating truck, and if an inter-city freight device such as a train or an automobile which needs to be parked in the middle is used in an inter-city, various freight devices in the city may also be directly docked with the inter-city freight device as long as the logistics directions of the two devices are consistent and the time and the place are matched. Therefore, the logistics system is more flexible in goods transportation and higher in efficiency.
Logistics system and cargo supervision method
As illustrated in the foregoing embodiments, the present invention provides a logistics system, as shown in fig. 99, which is a schematic block diagram of the system, and the logistics system includes a plurality of logistics apparatuses (e.g., a plurality of flow warehouses Q1 and a plurality of fixed-position warehouses Q4), an identification system Q2 and a database Q3, wherein at least some of the logistics apparatuses include a plurality of bay units, and the bay units are associated with the logistics apparatus where the logistics apparatuses are located. As in the foregoing embodiment, the number C0F11001 of the storage location unit of the stereoscopic warehouse, the first three characters represent the identification of the stereoscopic warehouse, in this embodiment, the stereoscopic warehouse may be a mobile warehouse, or a fixed location warehouse, the last five digits in the number represent the location number of the storage location unit in the stereoscopic warehouse, the storage location unit is associated with the logistics apparatus by setting the number for the storage location unit, and the storage location unit may be located in the logistics apparatus where the storage location unit is located by the number of the storage location unit.
The moving warehouse Q1 includes a stereoscopic warehouse and a transportation means, and in one embodiment, the moving warehouse Q1 includes a transportation device having a stereoscopic warehouse in each of the aforementioned embodiments, such as a mini-truck 9a, a local circulation truck 9b, a cargo airplane having a stereoscopic warehouse, a marine ship, a cargo train, and various long-distance and short-distance trucks, and the like. The fixed-position warehouse Q4, which is a complementary logistics device, such as the terminal express cabinet 10, includes a plurality of storage location units, each having a unique number, representing both the storage location unit itself and the express cabinet in which it is located.
The storage location unit houses a first turnaround box, such as the parent turnaround box 2 in the previous embodiment, and a plurality of second turnaround boxes, such as the child turnaround box 7, configured to house cargo. The specific structure is described with reference to the foregoing embodiments, and a description thereof will not be repeated. The first transfer box and the second transfer box have corresponding identity identifiers. When the goods enter the logistics system, the goods are positioned in the second transfer box, the association relationship between the goods and the second transfer box is established, the second transfer box is placed in the first transfer box, the association relationship between the second transfer box and the first transfer box is established, and the first transfer box is accommodated by the storage position unit no matter in the flow warehouse or the fixed position warehouse, so that the association relationship between the storage position unit and the first transfer box can be established, and the association relationship between the goods and the storage position unit can be obtained.
However, it should be noted that the aforementioned scheme of using the second transfer box is only an embodiment, and when the second transfer box is not used, the package of the second transfer box is marked with the identity of the goods as in the existing package, so that only the association relationship between the goods and the first transfer box and the association relationship between the first transfer box and the storage location unit where the first transfer box is located need to be established, and the association relationship between the goods and the storage location unit can also be obtained.
When goods in the invention move in one logistics device or are transferred among different logistics devices, the association relationship is changed. In one embodiment, the association is modified by the device that results in the change in the cargo location and sent to the database Q3 for storage. For example, in the foregoing embodiment, when an AGV in a stereoscopic warehouse carries a parent container, the identity binding relationship between the parent container and the storage location unit is changed. The sorting device can change the identity binding relationship between the sub turnover box and the mother turnover box when sorting the sub turnover box, and the AGV can modify the association relationship in real time and send a change message to the database Q3 for storage when carrying goods each time and when sorting the goods each time. The relationship between the goods and the stock space units recorded in the database Q3 is changed continuously throughout the logistics process until the goods are sent to the consignee, and the logistics process is ended.
The identification system Q2 can identify the goods entering the flow warehouse Q1 or the fixed position warehouse Q4 and the change of the goods through the association relationship between the goods and the warehouse position units, or the change of the goods among different flow warehouses Q1, flow warehouses Q1 and fixed position warehouses Q4.
In another embodiment, the logistics system further comprises a cargo oversight system Q5 configured to issue an alert in response to the location of the cargo not being in a scheduled bay unit. The cargo supervision system Q5 monitors the change of the association relationship between the cargo and the storage location unit of each cargo in the system, and when the association relationship between the cargo and the storage location unit of a cargo stops changing within a predetermined time, it can be determined that the position of the cargo is not in the scheduled storage location unit, that is, the cargo leaves the logistics system, because the cargo may be lost, illegal operation, accident, etc., at this time, an alarm will be issued. In one embodiment, when the alarm is issued, the logistics equipment, such as a certain mobile warehouse or a certain fixed position warehouse, where the goods leave the logistics system is located according to the latest association relationship between the goods and the warehouse location unit, so that the goods can be timely and specifically processed.
In another embodiment, the logistics system further comprises a location system Q6 configured to determine the location of the logistics apparatus, such as a geographic information location system, which can determine the location of each moving warehouse and each fixed location warehouse within the logistics system in real time. On the basis, the logistics system further comprises a scheduling system Q7 for scheduling the goods to be transferred among different logistics devices. With respect to logistics equipment, the dispatching of cargo includes receiving cargo and transferring the cargo outward. In one embodiment, the scheduling system Q7 determines whether a shipment needs to be scheduled based on the empty and occupied bin locations of the shipment in the logistics apparatus. For example, when a large portion of the bay units in a mobile or fixed-site warehouse are already occupied by goods, normal goods reception may be compromised if no more outward transfers are available. Therefore, the goods need to be dispatched outwards according to the number of occupied storage position units and free storage position units.
The scheduling system Q7 may schedule the cargo based on the direction of travel of the moving warehouse and the direction of logistics of the cargo when scheduling the cargo between different logistics devices. For example, when dispatching goods in a floating warehouse, the dispatching system Q7 determines the docking position of the goods transferred between the floating warehouses and the transferred goods based on the traveling direction of the floating warehouses and the logistics direction of the goods. When the mobile warehouse transfers goods at the butt joint position, the butt joint position providing equipment is not needed, and the mobile warehouse only needs to complete butt joint according to the self structure, such as the butt joint of the mini-truck and the urban circulating truck, or the butt joint of two urban circulating trucks and the like. The docking position can be flexibly selected because the docking does not need to depend on external assistance.
When dispatching goods from a moving warehouse, the dispatch system Q7 determines the goods to be transferred to and from the fixed-location warehouse based on the direction of travel of the moving warehouse and the direction of logistics of the goods and the location of the fixed-location warehouse. Goods are transferred between the express delivery cabinet and the mini-truck or between the express delivery robot/unmanned aerial vehicle and the express delivery cabinet as in the previous embodiment. In the cargo transportation process, when the cargo destination is changed or the time-dependent grade is changed, the dispatching system Q7 needs to reschedule the cargo, for example, re-determine the docked logistics equipment and the docking position.
In this embodiment, the adjusting system Q7, the location system Q6, the cargo supervision system Q5 and the database Q3 may be any one or more of the logistics control modules in fig. 72 or any one or more modules thereof.
The present invention also provides a method for supervising goods in a logistics system, as shown in fig. 100, which is a flow chart of the method for supervising goods according to an embodiment of the present invention, and the method includes:
step S1d, identifying the cargo entering the logistics apparatus. For example, the goods entering a logistics device can be determined according to the association relationship between the goods and the storage location unit. When the AGV carries goods into a warehouse, the RFID information of the parent turnover box is modified, the number of the bound warehouse location unit in the RFID information is modified into a transportation state, the goods currently in the warehouse can be identified according to the identity binding information of the parent turnover box and the child turnover box bound with the warehouse location unit and the binding information of the child turnover box and the goods, and the specific reference can be made to the process flow of the goods warehousing method.
And S2d, recording the association relationship between the goods in the logistics equipment and the storage location unit where the goods are located. After goods enter logistics equipment, when the AGV is carried to release the parent turnover box to the storage position unit, the serial number of the storage position unit is written into the RFID information of the parent turnover box, and the binding of the parent turnover box and the storage position unit is completed. Therefore, the association relationship between the goods and the storage location unit where the goods are located is determined, and the specific reference can be made to the storage process and the exchange process.
And step S3d, determining the change of the stock position unit of the goods in the logistics equipment. Since the logistics apparatuses need to sort goods during transportation or dock with other logistics apparatuses to receive or transfer goods to the outside, the positions of the goods in the logistics apparatuses need to be changed frequently. The position change includes changing a stock position unit occupied by the parent turnover box where the goods are located, changing the parent turnover box where the child turnover box where the goods are located, and the like. Each time the position of the goods changes, the device which changes the position of the goods, such as an AGV or a sorting device, changes the corresponding binding relationship, records the changed association relationship in a database, and can determine the position change of the goods through the change of the association relationship between the goods and the parent container, the storage location unit and the like.
Step S4d, identifying the change between the mobile warehouse and/or the mobile warehouse and the fixed position warehouse according to the association relationship between the goods and the warehouse location unit.
If the number of the stock location unit associated with the goods changes, whether the current change occurs between different logistics devices and which goods are transferred from each logistics device to which logistics device can be determined through the number of the stock location unit. For example, the stock location unit associated with the cargo is changed from C0F11001 to M3H34002, and since the first three digits represent the number of the logistics apparatus, the cargo is transferred from the logistics apparatus with the number of C0F to the logistics apparatus with the number of M3H, and is stored in the second stock location unit in the fourth column of the third layer of the logistics apparatus M3H. By inquiring the corresponding relation between the logistics equipment and the code, the specific logistics equipment can be determined. For example, the logistics equipment with code number C0F is a mini-van operating in xx province xx city, and the logistics equipment with code number M3H is a city recycle van in xx province xx city.
Step S5d, it is monitored whether the association relationship between the goods and the stock location unit changes within a predetermined time period. For example, the longest time period for the cargo to be transferred to the next logistics device in the current logistics device can be known according to the scheduling information of the cargo by the scheduling system, and the time period can be used as the predetermined time period. If the association of the goods with the stock location unit has not changed within the predetermined period of time, an alarm is issued at step S6 d. And positioning to specific logistics equipment according to the library position unit in the latest association relation. The alarm information may include cargo information, logistics information thereof, and the last logistics equipment.
By the supervision method, the phenomenon that the goods leave the logistics system due to goods loss, illegal operation, accidents and the like can be found in time, and specific logistics equipment with the phenomenon can be determined immediately, so that a solution can be provided in time.
Fig. 101 is a flowchart of a cargo scheduling method according to an embodiment of the present invention.
And S1e, acquiring the vacant storage unit rate of the target logistics equipment.
And step S2e, judging whether the vacant warehouse bit unit rate of the target logistics equipment is less than a preset value. If less than the predetermined value, the cargo received by the target logistics apparatus is reduced at step S3 e. If the vacant bay unit rate is greater than the predetermined value, the goods received by the target logistics apparatus are increased at step S4 e. Wherein, when the goods that the target logistics device should receive and the goods are transferred from the target logistics device, the logistics device which is in butt joint with the target logistics device needs to be determined. In one embodiment, the butt joint logistics equipment for goods transfer is determined through the running direction of the flow warehouse and the logistics direction of the goods, or the goods transferred between the flow warehouse and the fixed position warehouse are determined. For example, taking the target logistics device as an example, when the target logistics device is a flow warehouse, according to the running direction of the target flow warehouse and other flow warehouses and the logistics direction of the goods, a flow warehouse with the same logistics direction as the goods is determined as a docking flow warehouse, and the docking position of the two is determined according to the running route of the two. If there is no suitable mobile warehouse to dock with the target mobile warehouse, or the required time is too long, it can be determined by calculation that one fixed-location warehouse docks with the target mobile warehouse, and the target mobile warehouse transfers the goods to the fixed-location warehouse and then from the fixed-location warehouse to the other mobile warehouse.
In another embodiment, the shipment is also scheduled according to the age level. The aging grade is a logistics grade, such as express, ordinary and the like. When dispatching goods, the goods with high logistics level are dispatched preferentially, so that the goods with high logistics level can be delivered quickly and timely.
When the time-efficiency grade or the destination of the goods changes, the goods are rescheduled, namely the logistics equipment for transporting the goods and the butt joint between the logistics equipment are determined again.
The invention can monitor the whole process of the goods in the logistics system, can know the position of the goods in the logistics system in real time, and can find the goods leaving the system in the first time, thereby solving the accident in time. The invention can accurately and timely provide reasonable and appropriate logistics equipment for the dispatching of the goods according to the whole-course supervision information of the goods, thereby improving the logistics efficiency of the goods.
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.
