Description

Technical Field

[0001] This application relates to the field of warehousing equipment technology, and more specifically to a warehousing system. Background Technology

[0002] In the field of warehousing and logistics handling and picking, the shelf-to-person robotic picking system has changed the traditional human-to-goods logistics operation mode. Robots transport target shelves to the workstation, where workers or automated picking equipment can then pick the goods from the shelves. However, in this model, when warehousing and logistics companies pick goods according to orders, the lack of a pre-sorting process often results in only a few boxes being picked from each shelf, with the rest being unwanted by the order. This frequently leads to multiple shelves congregating at the workstation waiting to be picked. This requires a large number of handling robots to move the shelves, and a significant amount of time is wasted waiting for shelves to be moved to their designated locations at the workstation, greatly impacting the company's production efficiency.

[0003] Therefore, a warehousing system is needed to at least partially solve the above problems. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this application provides a warehousing system comprising:

[0006] Multiple movable vehicles, each including multiple placement positions for placing containers for storing goods;

[0007] A mobile vehicle docking area for docking the plurality of mobile vehicles;

[0008] At least one hub station for exchanging the containers between at least two of the mobile vehicles;

[0009] At least one workstation for picking the goods according to an order;

[0010] At least one automated handling device for moving the mobile vehicle between the mobile vehicle docking area, the hub station, and the workstation; and

[0011] A control device, coupled to the hub station, the workstation, and the automated transport equipment, for controlling the operation of the hub station, the workstation, and the automated transport equipment.

[0012] The warehousing system is configured to perform the following steps:

[0013] The container is selected based on the preset batch of orders received by the workstation;

[0014] The containers that are hit are marked as hit containers, and the containers that are not hit are marked as non-hit containers;

[0015] The movable vehicle containing the hit container is marked as a hit vehicle;

[0016] The hit vehicles parked in the mobile vehicle docking area are moved to at least one of the hub stations, wherein at least two of the hit vehicles are moved to the same hub station;

[0017] At the hub station, the non-hit container on at least one of the first hit vehicles is exchanged with the hit container on at least one other second hit vehicle;

[0018] The first hit vehicle, containing the hit container, which is docked at the hub station, is moved to the workstation.

[0019] According to the warehousing system of this application, based on the containers on the mobile carriers that are matched by orders, before the mobile carriers are moved to the workstations for picking, sorting is performed first, and the matched containers are organized into one or more mobile carriers. Then, picking is carried out on such mobile carriers, thereby improving the utilization rate of mobile carriers at the workstations, avoiding a large number of mobile carriers queuing at the workstations, and improving the picking efficiency of the workstations.

[0020] Optionally, the step of moving the first hit vehicle, which contains the hit container, from the hub station to the workstation includes:

[0021] When all the containers on the first hit vehicle at the hub station are hit containers, the first hit vehicle at the hub station is moved to the workstation; or

[0022] When a workstation becomes available, the first hit vehicle at the hub station will be moved to the available workstation; or

[0023] The warehousing system also includes a waiting area located closer to the workstation than the mobile vehicle docking area, for queuing the mobile vehicles for picking. The automated handling equipment is used to move the mobile vehicles between the mobile vehicle docking area, the hub station, the workstation, and the waiting area. The warehousing system is configured to predict the remaining working time for a workstation without a queue of mobile vehicles to complete picking of its currently selected mobile vehicle, and to predict the travel time for the selected vehicle to move from the hub station to the workstation without a queue of mobile vehicles. When the difference between the travel time and the remaining working time is less than a first preset value, the first selected vehicle at the hub station is moved to the workstation without a queue of mobile vehicles.

[0024] Alternatively, the warehousing system is configured to predict the remaining working time for a workstation without a queue of the mobile vehicle to complete the picking of the mobile vehicle currently being picked, and when the remaining working time is less than a second preset value, to move the first hit vehicle at the hub station that is closest to the workstation without a queue of the mobile vehicle to the workstation without a queue of the mobile vehicle.

[0025] According to this application, when the containers on the mobile vehicle are all hit containers, or the workstation is available, or the workstation is about to be available, the first hit vehicle at the hub station will be moved to the workstation.

[0026] Optionally, the warehousing system is configured to perform the following steps:

[0027] S110. Move the two hit vehicles parked in the mobile vehicle docking area to the same hub station, wherein the number of hit containers of the two hit vehicles are m and n respectively, and m<=n, and then execute step S120.

[0028] S120. The hit vehicles with n hit containers are designated as the first hit vehicles, and the hit vehicles with m hit containers are designated as the second hit vehicles. Then, step S130 is executed.

[0029] S130. Exchange the non-hit container on the first hit vehicle with the hit container on the second hit vehicle, and then execute step S140.

[0030] S140. Determine whether there are still any hit containers remaining on the second hit vehicle. If yes, proceed to step S150; otherwise, proceed to step S170.

[0031] S150. Determine whether there are still any non-hit containers remaining on the first hit vehicle. If yes, proceed to step S130; otherwise, proceed to step S160.

[0032] S160. Move the first hit vehicle to the workstation, and then execute step S200.

[0033] S170. Move the second hit vehicle back to the movable vehicle docking area, and then proceed to step S180.

[0034] S180. Determine whether there are still hit vehicles in the mobile vehicle docking area. If yes, proceed to step S190; otherwise, proceed to step S220.

[0035] S190. Move one of the hit vehicles from the mobile vehicle docking area to the same hub station and use it as the second hit vehicle, then execute step S130.

[0036] S200. Determine whether there are still hit vehicles in the mobile vehicle docking area. If yes, proceed to step S210; otherwise, proceed to step S220.

[0037] S210. Move one of the hit vehicles from the mobile vehicle docking area to the same hub station and use it as the first hit vehicle, then execute step S130.

[0038] S220. Determine whether there are still any hit containers remaining on the mobile vehicle at the same hub station. If yes, proceed to step S230; otherwise, proceed to step S240.

[0039] S230. The mobile vehicle located at the same hub station is moved to the workstation.

[0040] S240, The mobile vehicle at the same hub station is moved to the mobile vehicle docking area.

[0041] According to this application, when all containers on the mobile vehicles at the hub station are either hit containers or all are non-hit containers, the warehousing system moves new hit containers from the mobile vehicle docking area to the hub station, so that the cargo handling work can continue in an orderly manner.

[0042] Optionally, in step S110, the warehousing system is configured as follows:

[0043] Calculate the number of hit containers on each of the hit vehicles docked in the mobile vehicle docking area, determine the two hit vehicles based on the number of hit containers on each of the hit vehicles, and transport them to the same hub station.

[0044] Furthermore, in step S110,

[0045] The two hit containers with the fewest hit containers from the hit vehicles docked in the mobile vehicle docking area are moved to the same hub station; or

[0046] The two hit containers with the largest number of hit containers from the hit vehicles docked in the mobile vehicle docking area are moved to the same hub station; or

[0047] Two hit vehicles that are transported to the same hub station satisfy the condition that the sum of m and n is equal to the number of placement positions of the movable vehicle.

[0048] According to this application, the hit containers in the mobile vehicle docking area to be transported to the hub station can be flexibly selected. When the number of hit containers in two hit containers is minimal, the scattered hit containers can be quickly gathered together, thereby increasing the utilization rate of hit containers at the workstation. When the number of hit containers in two hit containers is maximum, the mobile vehicles can be filled with hit containers most quickly, thus replenishing the workstation most rapidly. When the sum of the number of hit containers in two hit containers equals the number of placement positions of the mobile vehicles, the two mobile vehicles complement each other, achieving the highest cargo handling efficiency.

[0049] Optionally, in step S190 and / or step S210,

[0050] The warehousing system is configured to move the vehicle with the smallest number of hit containers among the hit vehicles docked in the mobile vehicle docking area to the same hub station; or

[0051] The warehousing system is configured to move the vehicle with the largest number of hit containers among the hit vehicles docked in the mobile vehicle docking area to the same hub station; or

[0052] If the number of hit containers on the hit vehicles at the same hub station is x, the warehousing system is configured to move hit vehicles with a number of hit containers in the hit vehicles docked in the mobile vehicle docking area to the same hub station, wherein the sum of x and y is equal to the number of placement positions of the mobile vehicles.

[0053] According to this application, the hit vehicles to be supplied to the hub station in the mobile vehicle docking area can be flexibly selected. When the number of hit containers in the hit vehicles being supplied is minimal, the scattered hit containers can be quickly gathered together, thereby increasing the utilization rate of hit vehicles at the workstation. When the number of hit containers in the hit vehicles being supplied is maximum, the mobile vehicles can be filled with hit containers most quickly, thus supplying the workstation fastest. When the sum of the number of hit containers in the hit vehicles being supplied and the hit vehicles to be supplied equals the number of mobile vehicle placement positions, the two mobile vehicles complement each other, achieving the highest cargo handling efficiency.

[0054] Optionally, in step S110:

[0055] The control device first determines the two hit vehicles to be moved from the mobile vehicle docking area;

[0056] When multiple hub stations are available, the control device calculates the sum of the lengths of the movement paths of the two hit vehicles to be moved from the mobile vehicle docking area to each of the multiple available hub stations, and designates the hub station with the smallest sum of movement path lengths as the same hub station.

[0057] According to this application, during cargo handling, the warehousing system can first select the matched vehicle and then select the hub station. The hub station can be selected based on the principle of shortest path.

[0058] Optionally, in step S110:

[0059] The control device first identifies the same hub station;

[0060] When at least three of the hit vehicles are docked in the mobile vehicle docking area, the two hit vehicles with the shortest movement path to the same hub station are moved to the same hub station.

[0061] According to this application, when tallying cargo, a hub station can be selected first, followed by a selected vehicle. The selected vehicle can be chosen based on the shortest route principle.

[0062] Optionally, in step S130, the warehousing system is configured to determine the workstation associated with the first hit vehicle and preferentially exchange the hit container associated with the workstation associated with the first hit vehicle on the second hit vehicle to the first hit vehicle.

[0063] According to this application, during the picking process, not only are the picked containers placed together, but orders for picked containers are also processed at the same workstation as much as possible, thereby increasing the utilization rate of picked containers at the workstation and thus improving the picking efficiency of the workstation.

[0064] Optionally, in step S130, the warehousing system is configured to determine the order associated with the first hit vehicle and preferentially exchange the hit container associated with the order associated with the first hit vehicle on the second hit vehicle to the first hit vehicle.

[0065] According to this application, during the sorting process, not only are the picked containers placed centrally at the workstation, but efforts are also made to ensure that all picked containers are required for the same order, which can further improve the picking efficiency of the workstation.

[0066] Optionally, the warehousing system is configured to simultaneously move the hit vehicle from the mobile vehicle docking area to the hub station and the hit vehicle from the mobile vehicle docking area to the workstation.

[0067] According to this application, in order to make full use of the workstation, picking and sorting are carried out simultaneously, thereby ensuring the system's production efficiency.

[0068] Optionally, the hit vehicle with the largest number of hit containers among the hit vehicles parked in the mobile vehicle docking area is transported to the workstation.

[0069] According to this application, prioritizing the transport of vehicles with a large number of hit containers to the workstation for picking can ensure the utilization rate of mobile vehicles at the workstation, and also save more time for sorting work, thereby improving production efficiency.

[0070] Optionally, the warehousing system is configured such that when the capacity of the automated handling equipment cannot simultaneously meet the handling needs of the hub station and the workstation, the automated handling equipment prioritizes meeting the handling needs of the workstation.

[0071] The handling requirements of the hub station include: moving the hit vehicles in the mobile vehicle docking area to the hub station and moving mobile vehicles at the hub station that do not have the hit containers to the mobile vehicle docking area.

[0072] The handling requirements of the workstation include: moving the selected vehicles from the mobile vehicle docking area to the workstation; moving the selected vehicles from the hub station to the workstation; moving the selected vehicles from the waiting area to the workstation; and moving the mobile vehicles that have been picked at the workstation to the mobile vehicle docking area.

[0073] The waiting area is closer to the workstation than the mobile vehicle docking area, so that the hit vehicles can queue up for picking.

[0074] According to this application, when the capacity of automated handling equipment is insufficient, the needs of the workstations will be prioritized to ensure that production does not stop.

[0075] Optionally, the warehousing system is configured to configure the number of workstations according to one or more of the following parameters:

[0076] The total capacity of the warehousing system, the length and width of the site, the number of automated handling equipment, the number of transverse aisles in the mobile vehicle docking area, the number of longitudinal aisles in the mobile vehicle docking area, the total number of SKU types in the warehouse, the sales rate of the goods, the single-line ratio of the orders, the number of partitions in the picking wall, the picking time for a single item of the goods, and the maximum moving speed of the automated handling equipment.

[0077] According to this application, the number of workstations in the warehousing system is configured by comprehensively considering various factors in order to optimize the resource allocation of the warehousing system.

[0078] Optionally, the warehousing system is configured to configure the number of hub stations according to one or more of the following parameters:

[0079] The total capacity of the warehousing system, site length, site width, number of automated handling equipment, number of transverse aisles in the mobile vehicle docking area, number of longitudinal aisles in the mobile vehicle docking area, total SKU types in the warehouse, sales percentage of the goods, single-row ratio of the orders, number of partitions in the picking wall, picking time for a single item of the goods, maximum moving speed of the automated handling equipment, number of site zones, transfer time of the mobile vehicles, and target hit rate of the containers of the mobile vehicles for the orders.

[0080] According to this application, the number of hub stations in the warehousing system is configured by comprehensively considering various factors in order to optimize the resource allocation of the warehousing system.

[0081] Optionally, the warehousing system is configured to configure the number of automated handling equipment according to the number of workstations and / or the number of hub stations.

[0082] According to this application, the number of automated handling equipment is configured based on the number of workstations and / or hub stations in the warehousing system to optimize the resource allocation of the warehousing system.

[0083] Optionally, the warehousing system is configured to set the location of the hub station according to one or more of the following parameters:

[0084] The length of the site, the width of the site, and the number of the hub stations.

[0085] According to this application, the warehousing system comprehensively considers multiple factors to determine the location of the hub station in order to optimize the allocation of warehousing system resources.

[0086] Optionally, the warehousing system is configured to dispatch all received orders to the workstation in batches.

[0087] According to this application, orders are dispatched to workstations in batches, which facilitates the overall management of orders by batch and improves production efficiency.

[0088] Optionally, the hub station includes:

[0089] At least one cache bit is used to place the container; and

[0090] A container handling device, coupled to the control device, is used to move the container between the placement position and the buffer position.

[0091] Furthermore, the hub station also includes:

[0092] support frame; and

[0093] At least one guiding mechanism is disposed to the support frame, the guiding mechanism being movable laterally and vertically relative to the support frame.

[0094] The buffer position is located on the support frame or the guide mechanism, and the container picking and placing device is located on the guide mechanism.

[0095] Furthermore, the guiding mechanism includes:

[0100] According to this application, the hub station has a reasonable structure and can achieve the expected cargo handling function.

[0101] Optionally, the warehousing system is configured as follows:

[0102] First, move one of the first hit vehicle and the second hit vehicle to the same hub station, place the container on it that needs to be swapped to the other of the first hit vehicle and the second hit vehicle in the buffer position, and then move the first hit vehicle and the second hit vehicle back to the mobile vehicle docking area.

[0103] Then, the other of the first hit vehicle and the second hit vehicle is moved to the same hub station, and the container to be swapped thereto is placed on it from the cache position.

[0104] According to this application, when there are sufficient buffer slots, it is not necessary for the first hit vehicle and the second hit vehicle to be accepted for cargo handling at the hub station at the same time. This improves the flexibility of scheduling to a certain extent and can also save the area occupied by the hub station. Attached Figure Description

[0130] It should be noted that the terms “up,” “down,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this article are for illustrative purposes only and are not intended to be restrictive.

[0131] This application provides a warehousing system.

[0132] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0133] like Figure 1 As shown, in a preferred embodiment, the warehousing system 100 includes a plurality of mobile vehicles 10, a mobile vehicle docking area 20, at least one hub station 30, at least one automated handling equipment 40, at least one workstation 60, and a control device (not shown).

[0134] The movable vehicle 10 includes multiple placement positions 15 for placing containers 50 (e.g., ...). Figure 2 (As shown), container 50 is used to store goods. Mobile vehicle docking area 20 is used to dock multiple mobile vehicles 10. Hub station 30 is used to adjust the placement of multiple containers 50 on mobile vehicles 10, including adjusting the position of multiple containers 50 on the same mobile vehicle 10, and also including exchanging containers 50 between at least two mobile vehicles 10. Workstation 60 includes at least one picking station for processing containers 50 (e.g., removing items from containers 50 or placing items into containers 50). In other words, the workstation is at least used for picking goods according to orders. Automated handling equipment 40 is used to move mobile vehicles 10 between mobile vehicle docking area 20, hub station 30, and workstation 60. Automated handling equipment 40 is, for example, a handling robot that can move under mobile vehicles 10 and then lift mobile vehicles 10 off the ground, thereby moving mobile vehicles 10. Mobile vehicles 10 can be, for example, shelves. The control device is coupled to the hub station 30, workstation 60, and automated handling equipment 40 to control the operation of the hub station 30, workstation 60, and automated handling equipment 40. For example, the control device can control the movement of the automated handling equipment 40, control the operation of adjusting the container placement position at the hub station 30, and control the goods picking process at the workstation 60.

[0135] The warehousing system 100 also includes a waiting area 70 located closer to the workstation 60 than the mobile vehicle docking area 20, for queuing mobile vehicles 10 for picking. Preferably, each workstation 60 is equipped with a corresponding waiting area 70. The waiting area 70 can be considered as part of the workstation 60. Automated handling equipment 40 is used to move mobile vehicles 10 between the mobile vehicle docking area 20, the hub station 30, the workstation 60, and the waiting area 70.

[0136] Specifically, such as Figure 2 As shown, the hub station 30 includes a support frame 31, a guiding mechanism 32, a container pick-and-place device 33, and a buffer position (not shown, but may be provided to the support frame 31 or the guiding mechanism 32). The guiding mechanism 32 is provided to the support frame 31. The guiding mechanism 32 is movable laterally and vertically relative to the support frame 31. The container pick-and-place device 33 is provided to the guiding mechanism 32, thereby allowing the container pick-and-place device 33 to move laterally and vertically relative to the support frame 31. The container pick-and-place device 33 is coupled to a control device. When the automated handling equipment 40, under the control of the control device, transports the movable carrier 10 to a preset working position relative to the support frame 31, the container pick-and-place device 33 moves laterally and vertically to reach a position corresponding to the placement position 15, thereby allowing the container 50 to be picked up or placed at the placement position 15.

[0137] Specifically, the guiding mechanism 32 includes a lateral moving device 34, a moving rod 35, and a vertical moving device 36. The lateral moving device 34 is disposed to the support frame 31 and coupled to a control device. The lateral moving device 34 is configured to move laterally relative to the support frame 31. The moving rod 35 extends vertically and is disposed to the lateral moving device 34, allowing it to move laterally relative to the support frame 31. The vertical moving device 36 is disposed to the moving rod 35 and coupled to the control device. The vertical moving device 36 is configured to move vertically relative to the moving rod 35. A container picking / placing device 33 is disposed to the vertical moving device 36, allowing it to move vertically relative to the moving rod 35. Therefore, the container picking / placing device 33 can move both laterally and vertically on the support frame 31. A buffer position is also used to place the container 50. Therefore, the container handling device 33 can move the container 50 between different placement positions 15 or between placement position 15 and buffer position, thereby adjusting the placement position of the container 50 on the same movable carrier 10 or moving the container 50 between multiple movable carriers 10.

[0138] exist Figure 2 In the illustrated embodiment, the hub station 30 includes only one guiding mechanism 32. In other embodiments shown in this application, the support frame 31 is larger, allowing for the simultaneous installation of multiple guiding mechanisms 32, effectively combining multiple... Figure 2The hub station 30 shown is integrated, which allows more mobile vehicles 10 to be used for cargo handling at the same time.

[0139] To solve the problems in the background art, such as Figure 3 As shown, in a preferred embodiment, the warehousing system 100 is configured to perform the following steps:

[0140] S10. Hit container 50 according to the preset batch of orders received by workstation 60;

[0141] S20. Mark the hit container 50 as a hit container, and mark the unhit container 50 as an unhit container;

[0142] S30. Mark the movable vehicle 10 containing the hit container as a hit vehicle;

[0143] S40. Transport the hit vehicles parked in the movable vehicle docking area 20 to at least one hub station 30, wherein at least two hit vehicles are transported to the same hub station 30.

[0144] S50, at hub station 30, at least one of the non-hit containers on the first hit vehicle is exchanged with at least one hit container on the second hit vehicle.

[0145] S60, Move the first hit vehicle containing the hit container, which is parked at hub station 30, to work station 60.

[0146] As can be seen, in this application, a pure sorting workstation—hub station 30—is set up in the warehouse. Based on the container 50 matched by the order, a robot transports the corresponding container to the sorting workstation. Through this workstation, the containers 50 required for the order task are moved from the original movable carriers 10 (e.g., shelves) to a single movable carrier 10 (understandably, not limited to one). After assembly, the robot transports them to workstation 60 where manual (or equipment) order picking is completed. In this way, queuing time is shifted from workstation 60 (manual workstation) to hub station 30 (unmanned sorting workstation), effectively improving the efficiency of manual work and thus increasing production efficiency during peak periods.

[0147] The warehousing system 100 is configured to dispatch all received orders to workstation 60 in batches. In step S10, the control device selects container 50 based on the preset batches of orders received by workstation 60. The preset batches may be, for example, 1 batch, 2 batches, 3 batches, etc.

[0148] like Figure 4 As shown, preferably, steps S40 and S50 may further include the following steps.

[0149] S110. Move the two hit vehicles parked in the movable vehicle docking area 20 to the same hub station 30, wherein the number of hit containers of the two hit vehicles are m and n respectively, and m<=n, and then execute step S120.

[0150] Understandably, in this step, the control device must control the automated handling equipment 40 to move the two hit containers to the same hub station 30 in order to complete the expected cargo handling work, so that as many containers 50 on the mobile carrier 10 as possible become hit containers.

[0151] S120. Take the hit vehicles with n hit containers as the first hit vehicles, and the hit vehicles with m hit containers as the second hit vehicles, and then execute step S130.

[0152] S130, swap the non-hit container on the first hit vehicle with the hit container on the second hit vehicle, and then execute step S140.

[0153] In this application, the warehousing system 100 is configured to transfer all hit containers to a first hit carrier, and then send the first hit carrier to workstation 60 to perform picking tasks.

[0154] S140. Determine whether there are still any hit containers remaining on the second hit vehicle. If yes, proceed to step S150; otherwise, proceed to step S170.

[0155] S150. Determine whether there are any unhitted containers remaining on the first hit vehicle. If yes, proceed to step S130; otherwise, proceed to step S160.

[0156] S160. Move the first hit vehicle to workstation 60, and then execute step S200.

[0157] S170. Move the second hit vehicle back to the movable vehicle docking area 20, and then proceed to step S180.

[0158] S180. Determine whether there are any hit vehicles in the movable vehicle docking area 20. If yes, proceed to step S190; otherwise, proceed to step S220.

[0159] S190, Move a hit vehicle from the mobile vehicle docking area 20 to the same hub station 30 and use it as the second hit vehicle, then proceed to step S130.

[0160] S200. Determine whether there are any hit vehicles in the movable vehicle docking area 20. If yes, proceed to step S210; otherwise, proceed to step S220.

[0161] S210, Move a hit vehicle from the mobile vehicle docking area 20 to the same hub station 30 and use it as the first hit vehicle, then proceed to step S130.

[0162] In steps S140 to S210, if the first hit vehicle is fully loaded with hit containers, it is moved to workstation 60. Then, a new hit vehicle is moved from the mobile vehicle docking area 20 to hub station 30 and used as a new first hit vehicle. The hit containers that have not yet been transferred from the existing second hit vehicle are then transferred to this new first hit vehicle. If the second hit vehicle has no hit containers, it is moved back to the mobile vehicle docking area 20. Then, a new hit vehicle is moved from the mobile vehicle docking area 20 to hub station 30 and used as a new second hit vehicle. The hit containers on this new second hit vehicle are then transferred to the existing first hit vehicle.

[0163] S220. Determine whether there are still hit containers remaining on the mobile vehicle 10 at the same hub station 30. If yes, proceed to step S230; otherwise, proceed to step S240.

[0164] S230, The mobile vehicle 10 at the same hub station 30 is moved to the work station.

[0165] S240, Move the mobile vehicle 10 at the same hub station 30 to the mobile vehicle docking area 20.

[0166] In steps S220 to S240, when there are no more hit vehicles in the mobile vehicle docking area 20, it means that all hit vehicles have undergone the tallying process. At this time, if there are no more hit containers on the mobile vehicle 10 at the hub station 30, it means that all hit containers on the mobile vehicle 10 (e.g., the second hit vehicle) have been transferred, and the mobile vehicle 10 does not need to participate in picking. Therefore, it should be returned to the mobile vehicle docking area 20, and the tallying work ends. If there are hit containers on the mobile vehicle 10 at the hub station 30, it means that the mobile vehicle 10 (e.g., the first hit vehicle) has received hit containers, and the mobile vehicle 10 needs to participate in picking. Therefore, it should be sent to the workstation 60, and the tallying work ends.

[0167] Understandably, since hub station 30 is equipped with buffer slots, the first and second hit vehicles do not need to be processed simultaneously at the same hub station 30. Instead, one of them—for example, hit vehicle A—can be sent to hub station 30 first, and the container 50 on hit vehicle A that needs to be exchanged to the other of the first and second hit vehicles—for example, hit vehicle B—can be placed in the buffer slot. Then, hit vehicle A is moved back to the mobile vehicle docking area. Next, hit vehicle B is moved to the same hub station 30, and the container 50 that needs to be exchanged to hit vehicle B is moved from the buffer slot to hit vehicle B. When the number of buffer slots is sufficient relative to the number of containers 50 that need to be exchanged to mobile vehicles, this method can improve scheduling flexibility to a certain extent and also save the floor space of hub station 30.

[0168] The sorting process in steps S110 to S240 can consolidate the scattered hit containers, thereby improving the efficiency of workstation 60. In order to prioritize production and ensure that workstation 60 is fully utilized, the warehousing system 100 is also configured to simultaneously move hit containers from the mobile container docking area 20 to the hub station 30 and from the mobile container docking area to the workstation, so that picking and sorting can be carried out at the same time.

[0169] For example, while sorting goods, the vehicle with the largest number of hit containers among the hit vehicles parked in the movable vehicle docking area 20 is moved to workstation 60. In this way, the hit vehicle stays at workstation 60 for a longer period of time, which can save time for sorting goods.

[0170] For example, when the capacity of the automated handling equipment 40 cannot simultaneously meet the handling needs of both the hub station 30 and the workstation 60, the automated handling equipment 40 prioritizes meeting the handling needs of the workstation. The handling needs of the hub station 30 include: moving hit vehicles from the mobile vehicle docking area 20 to the hub station 30 and moving (returning) mobile vehicles 10 without hit containers from the hub station 30 to the mobile vehicle docking area 20. The handling needs of the workstation 60 include: moving hit vehicles from the mobile vehicle docking area 20 to the workstation 60, moving hit vehicles from the hub station 30 to the workstation 60, moving hit vehicles from the waiting area 70 to the workstation 60, and moving (returning) picked mobile vehicles 10 from the workstation 60 to the mobile vehicle docking area 20. In other words, when both hub station 30 and workstation 60 require automated handling equipment 40 to move or remove mobile vehicles 10 from them, the warehousing system 100 prioritizes the needs of workstation 60 to maximize the utilization of workstation 60.

[0171] During the sorting process in steps S110 to S240, the warehouse system 100 is configured to use various methods to improve the sorting efficiency so that the sorting work and picking work are better matched.

[0172] In step S110, preferably, the control device calculates the number of hit containers on each hit vehicle docked in the mobile vehicle docking area 20, determines two hit vehicles based on the number of hit containers on each hit vehicle, and transports them to the same hub station 30.

[0173] For example, in some implementations, in step S110, the number of hit containers in one of the two hit vehicles transported to the same hub station 30 is m, and the number of hit containers in the other is n. The sum of m and n is equal to the number of placement positions of the movable vehicle. In this way, the two hit vehicles complement each other, so that after sorting, one of the hit vehicles is filled with hit containers, thus maximizing sorting efficiency.

[0174] For example, in some embodiments, in step S110, the two hit containers with the fewest hit containers from the hit containers docked in the mobile vehicle docking area 20 are moved to the same hub station 30. It is understandable that when a hit container has few hit containers, the utilization rate of such a hit container at workstation 60 is low, which is a major reason why a large number of mobile vehicles 10 are queuing at workstation 60. Prioritizing the handling of hit containers from hit containers with fewer hit containers helps to quickly gather the scattered hit containers, thereby increasing the utilization rate of hit containers at workstation 60.

[0175] For example, in some embodiments, in step S110, the two hit containers with the largest number of hit containers from the hit vehicles docked in the movable vehicle docking area 20 are moved to the same hub station 30. In this way, at the hub station 30, all containers on one of the hit vehicles can be quickly made into hit containers, thereby quickly replenishing the work station 60 and ensuring the working efficiency of the work station 60.

[0176] In step S110, the control device may first determine the two hit vehicles to be moved from the mobile vehicle docking area 20, and then determine which hub station 30 to move these two hit vehicles to. Alternatively, the control device may first select a hub station 30, and then determine which two hit vehicles to move to that hub station 30.

[0177] For example, in step S110, when multiple hub stations 30 are available, the control device first determines the two selected vehicles to be moved from the mobile vehicle docking area 20. Then, the control device calculates the sum of the movement paths of the two selected vehicles to be moved from the mobile vehicle docking area 20 to each of the multiple available hub stations 30, and selects the hub station 30 with the smallest sum of movement path lengths as the same hub station 30 to which the two selected vehicles should be transported. In this way, the movement path is minimized, which can improve cargo handling efficiency.

[0178] For example, in step S110, when at least three hit vehicles are docked in the mobile vehicle docking area 20, the control device first determines the same hub station 30 to which two hit vehicles are to be transported. Then, the two hit vehicles with the shortest travel path to the same hub station 30 are moved to that hub station 30. In this way, the shortest travel path can improve cargo handling efficiency.

[0179] In step 130, preferably, the warehousing system 100 is configured to identify the workstation 60 associated with the first hit carrier and preferentially exchange the hit containers associated with the workstation 60 associated with the first hit carrier on the second hit carrier to the first hit carrier. In this way, the containers 50 on the first hit carrier are not only all hit containers, but also hit containers bound to the same workstation 60. When picking is performed at this workstation 60, the utilization rate of the first hit carrier is greatly improved, and the first hit carrier is picked at as few workstations 60 as possible, thus improving production efficiency to a certain extent.

[0180] In step S130, more preferably, the warehousing system 100 is configured to determine the order associated with the first hit carrier and prioritize exchanging the hit containers associated with the order associated with the first hit carrier on the second hit carrier to the first hit carrier. In this way, the containers 50 on the first hit carrier are not only all hit containers, but also hit containers bound to the same order. When picking is performed at workstation 60, the improved matching rate between the first hit carrier and the order allows orders to be fulfilled more quickly, further improving production efficiency. In steps S190 and / or S210, preferably, the warehousing system 100 is configured to move the hit carrier with the smallest number of hit containers from the hit carrier docking area 20 to the same hub station 30. This is understandably beneficial for quickly consolidating scattered hit containers, thereby increasing the utilization rate of hit carriers at workstation 60.

[0181] Alternatively, in steps S190 and / or S210, the storage system 100 is configured to move the hit vehicle with the largest number of hit containers from the hit vehicles docked in the mobile vehicle docking area 20 to the same hub station 30. Understandably, this facilitates quickly storing all hit containers in the first hit vehicle, thereby rapidly replenishing the workstation 60.

[0182] Alternatively, in steps S190 and / or S210, if the number of hit containers on the hit vehicles (first hit vehicle or second hit vehicle) at the same hub station 30 is x, the warehousing system 100 is configured to move hit vehicles with y hit containers from the hit vehicles docked in the mobile vehicle docking area 20 to the same hub station 30, where the sum of x and y equals the number of placement positions for the mobile vehicles. Understandably, this ensures that the number of hit containers on newly delivered hit vehicles to the hub station 30 is exactly complementary to the number of hit containers on previously delivered hit vehicles that have already participated in the sorting process. This allows for the sorting process to ensure that one of the hit vehicles is entirely filled with hit containers, maximizing sorting efficiency.

[0183] After the cargo handling is completed, in step S60, when all containers 50 on the first hit container at hub station 30 are hit containers, the first hit container at hub station 30 will be moved to work station 60.

[0184] Alternatively, in step S60, when a workstation 60 is idle, in order to improve the utilization rate of the workstation 60, regardless of whether the first hit vehicle is full of hit containers, the first hit vehicle in the hub station 30 will be moved to the idle workstation 60.

[0185] Alternatively, in step S60, the warehousing system 100 is configured to predict the remaining working time for a workstation 60 with no movable vehicles 10 in the queue to complete the picking of its currently selected movable vehicle 10, and to predict the travel time for a hit vehicle to move from the hub station 30 to the workstation 60 with no movable vehicles 10 in the queue. When the difference between the travel time and the remaining working time is less than a first preset value (e.g., 30 to 60 seconds), the first hit vehicle in the hub station 30 is moved to the workstation 60 with no movable vehicles 10 in the queue. That is, when the control device anticipates that a workstation 60 will soon be idle, it promptly moves a hit vehicle to that workstation 60, ensuring seamless connection of hit vehicles in the workstation 60 and making full use of the workstation 60.

[0186] Alternatively, in step S60, the warehousing system is configured to predict the remaining working time for the workstation 60 with no movable vehicles 10 queuing to complete the picking of its currently selected movable vehicle 10. When the remaining working time is less than a second preset value (e.g., 2 to 5 minutes), the first selected vehicle from the hub station 30 that is closest to the workstation 60 with no movable vehicles 10 queuing will be moved to the workstation 60 with no movable vehicles 10 queuing. That is, when the control device anticipates that a workstation 60 will soon be idle, it can dispatch the first selected vehicle nearby, which can also ensure the utilization rate of the workstation 60.

[0187] As can be seen from the above introduction, in the warehousing system 100, the number of workstations 60, hub stations 30, and automated handling equipment 40 must match the order volume (especially the order volume during peak periods), and the three must also match each other to achieve a balanced working state, that is, neither a certain link will be oversupplied nor a certain link will be severely lacking.

[0188] Preferably, the warehousing system 100 is configured to have a number of workstations 60 configured according to one or more of the following parameters: total capacity of the warehousing system 100, site length, site width, number of automated handling equipment 40, number of transverse aisles in the mobile vehicle docking area 20, number of longitudinal aisles in the mobile vehicle docking area 20, total number of SKU types in the warehouse, sales rate of goods, order line ratio, number of pick wall partitions, picking time for a single item, and maximum moving speed of the automated handling equipment 40.

[0189] Preferably, the warehousing system 100 is configured to configure the number of hub stations 30 according to one or more of the following parameters: total capacity of the warehousing system 100, site length, site width, number of automated handling equipment 40, number of transverse aisles of mobile vehicle docking area 20, number of longitudinal aisles of mobile vehicle docking area 20, total number of SKU types in the warehouse, sales rate of goods, order one-line ratio, number of pick wall partitions, picking time of a single item, maximum moving speed of automated handling equipment 40, number of site partitions, transfer time of mobile vehicle 10, and target hit rate of mobile vehicle 10 containers 50 to orders.

[0190] Preferably, the warehousing system 100 is configured to configure the number of automated handling equipment 40 according to the number of workstations 60 and / or the number of hub stations 30. Preferably, the warehousing system 100 is configured to determine the other two based on any one of the number of workstations 60, the number of hub stations 30, and the number of automated handling equipment 40.

[0191] Furthermore, the location of the hub station 30 is also important. A well-designed location for the hub station 30 can reduce the average travel distance of hit vehicles to a certain extent, thereby saving costs and improving production and sorting efficiency. Preferably, the warehousing system 100 is configured to set the location of the hub station 30 according to one or more of the following parameters: site length, site width, and the number of hub stations 30.

[0192] According to the warehousing system of this application, based on the containers on the mobile carriers that are matched by orders, before the mobile carriers are moved to the workstations for picking, sorting is performed first, and the matched containers are organized into one or more mobile carriers. Then, picking is carried out on such mobile carriers, thereby improving the utilization rate of mobile carriers at the workstations, avoiding a large number of mobile carriers queuing at the workstations, and improving the picking efficiency of the workstations.
