DETAILED DESCRIPTION OF THE INVENTION

[0047] In order to clarify the objectives, technical solutions, and advantages of the embodiments of the present disclosure, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Of course, the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. Generally, the assemblies of the embodiments of the present disclosure described and shown in the drawings can be arranged and configured in various configurations. Therefore, the detailed descriptions of the embodiments of the present disclosure provided in the drawings below are not intended to limit the scope of the claimed disclosure, but merely represent selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without requiring creative efforts fall within the scope of protection of the present disclosure.

[0048] In addition, the terms "first," "second," etc. in the specification, claims, and drawings of the embodiments of the present disclosure are not necessarily intended to describe a particular order or chronological order, but are intended to distinguish between similar objects. It should be understood that the data used in this manner may be interchanged where appropriate so that the embodiments described herein can be implemented in an order other than that shown or described herein.

[0049] As used herein, "plurality or some" refers to two or more than two. "And / or" is used to describe the relationship between related objects and means that there can be three types of relationship; for example, A and / or B can mean that A exists alone, A and B exist simultaneously, or B exists alone. The symbol " / " generally means that the related objects before and after it are in an "or" relationship.

[0050] Currently, when an existing warehouse storage system receives an order, it calls an automated transport device, which transfers a rack storing a container containing the goods in the order from the rack storage area to a picking workspace. A container unloading device transports the container from the rack to the picking workspace for picking, and after a worker completes the picking, the container unloading device returns the container to the rack, and finally the automated transport device returns the rack from the rack dock area to the rack storage area.

[0051] As can be seen from this, the existing warehouse storage system has to call the corresponding rack every time a picking order is received, which has the problem of a relatively large workload for the automated transport device. In particular, the current picking workstations have a small number of temporary storage locations, and when pickers perform picking operations at the workstations, if there are SKUs that are frequently released, such as popular products, best-selling products, or prizes, the racks need to be transported frequently. In addition, the current picking workstations have a large amount of empty space, resulting in low space utilization.

[0052] Therefore, the present invention provides a warehouse storage system including a workstation area, a rack docking area, a multi-function area, and a container loading / unloading device, wherein the workstation area includes a picking workspace, the rack docking area is arranged for use as a docking location for racks, the multi-function area includes at least one storage location configured for use as a storage location for storing containers transferred from the picking workspace or the racks, and the container unloading device is configured to transfer containers between the workstation area, the rack docking area, and the multi-function area.

[0053] It should be noted that the racks in the warehouse storage system of the present invention do not only include racks in the traditional sense, but also include trays, material storage shelves or other types of load storage devices. The racks can be moved between different areas of the warehouse by automated transport devices or other mobile devices, i.e., the racks are configured as mobile carriers that can be moved between different areas of the warehouse.

[0054] On the other hand, the automatic transport device for transporting racks in the present invention is not a traditional automatic transport device for transporting racks, but any device that can transport racks.

[0055] In addition, the containers in the present invention include packing boxes, trays, pallets, tray temporary storage shelves, etc., and here, packing boxes include boxes such as storage boxes used to store different types of cargo, and also include specialized boxes used to store specific cargo, such as shoe cases, and in terms of material, packing boxes may be cardboard boxes, plastic boxes, iron boxes, etc.

[0056] This warehouse storage system can temporarily store containers that meet specified conditions in a multi-function area in advance based on information such as the frequency of cargo demand during a specified time period, and when a picking order related to these specified conditions is received, there is no need to call an automatic transport device to transport a rack containing the corresponding container; the container loading and unloading device simply transfers the corresponding container from the multi-function area to the picking work space, and after picking is complete, the container unloading device simply returns the container to the multi-function area, thereby reducing the workload of the automatic transport device.

[0057] For easier understanding, the specific structure and operation principle of this warehouse storage system will be described in detail below with reference to specific embodiments with reference to Figures 1 to 10. It should be noted that ordinal numbers such as "first", "second", etc. will be used to distinguish between containers for clear description, and it should be understood that these ordinal numbers do not limit the scope of protection of the present invention. (Warehouse storage system example 1)

[0058] 1, in this embodiment, the warehouse storage system includes a workstation area, a rack area, a multi-function area, and a container loading / unloading device. For a clearer understanding of the specific structure of the warehouse storage system, please also refer to FIGS. 2 to 4.

[0059] Here, the workstation area includes at least one picking workspace, which is configured to be used to store a container so that a worker or a picking robot can pick a parcel from the container that matches an order requirement and then place the parcel on an automated transport device or conveyor belt.

[0060] The picking workspace includes a first support frame and a first guide mechanism provided on the first support frame, the first guide mechanism being configured to be used to assist the container loading / unloading device in loading and unloading the container.

[0061] Specifically, the first support frame includes a first bracket 10, a first left side standing board 11, and a first right side standing board 12, where the first left side standing board 11 and the first right side standing board 12 are mounted in parallel to each other and spaced apart from each other on the first bracket 10. The function of the first bracket 10 is to raise the first left side standing board 11 and the first right side standing board 12 to a predetermined height above the floor surface so that an operator or a picking robot can easily pick packages.

[0062] The first guide mechanism includes a plurality of first rollers 13 provided between a first left standing plate 11 and a first right standing plate 12 in parallel with each other and rotatably spaced apart from each other.

[0063] After the container loading / unloading device places the container in the picking workspace, if it is considered that it is difficult for a worker or a picking robot to perform a picking operation at the current location of the container, the rolling characteristics of the first guide mechanism may be used to push the container from its current location to a position where it is easier to operate with a small force.

[0064] The rack stay area is located near the picking work space, and can accommodate at least two racks 20, thereby enabling the warehouse storage system to quickly pick a greater variety or quantity of items per unit time.

[0065] Continuing to refer to FIG. 1, in this example, the present warehouse storage system includes a plurality of picking workspaces spaced apart in a horizontal direction.

[0066] More specifically, the multiple picking workspaces are spaced apart along the X-axis direction. This allows multiple workers or picking robots to simultaneously pick items in the warehouse storage system, and those skilled in the art can infinitely expand the scope of application to suit various use cases.

[0067] According to some other embodiments of the present application, the multiple picking workspaces of the present application may be spaced apart in sequence along the Z-axis direction, thereby creating different heights between each picking workspace and the floor, facilitating picking by workers of different heights, thereby improving the picking comfort of the workers and further improving the picking efficiency of the workers.

[0068] According to some other embodiments of the present application, the plurality of picking workspaces of the present application may be spaced apart sequentially along the Y axis in a horizontal plane, thereby allowing a plurality of workers to pick facing each other.

[0069] Continuing to refer to FIG. 1, in this embodiment, the multi-function area of ​​the present application includes a plurality of storage locations, each storage location including a second support frame and a second guide mechanism provided on the second support frame, the second guide mechanism configured to be used by a container loading / unloading device to assist in loading and unloading containers.

[0070] In detail, the second support frame includes a second bracket 30, a second left side upright plate 31, and a second right side upright plate 32, where the second left side upright plate 31 and the second right side upright plate 32 are mounted on the second bracket 30 in parallel with and spaced apart from each other.

[0071] The second guide mechanism includes a plurality of second rollers 33 provided between a second left standing plate 31 and a second right standing plate 32 in parallel with each other and rotatably spaced apart from each other.

[0072] The storage location can be fixed to the fixed wall of the warehouse by the second bracket 30, or fixed to the picking workspace by an auxiliary bracket, ensuring that the multi-function area is located above the picking workspace and making full use of the available space above the picking workspace in the warehouse.

[0073] According to some other embodiments of the present application, the multi-function area of ​​the present application may be provided below the picking workspace, and the second bracket 30 may be fixed to the floor of the warehouse by a fastener such as a chemical anchor.

[0074] According to some other embodiments of the present application, the multi-function area of ​​the present application is provided near the picking work space, i.e., the multi-function area is provided close to the picking work space. Similarly, the second bracket 30 may be fixed to the warehouse floor by a fastener such as a chemical anchor.

[0075] In this embodiment, each storage location is used to store at least one container. It should be further noted that the above structure is only one implementation of the storage location, and the storage location may adopt other structures as long as they can store containers.

[0076] To improve the storage capacity of the multi-functional area, and still referring to Figure 1, in this embodiment, the multi-functional area includes a plurality of storage locations, some of which are spaced apart vertically and some of which are spaced apart horizontally, i.e., in this embodiment, the plurality of storage locations are spaced apart in a mixed manner both vertically and horizontally.

[0077] It is understood that the specific number of storage locations depends on the size of the space above the picking workspace, and those skilled in the art can select the appropriate number and arrangement method according to the actual situation.

[0078] Of course, in some other embodiments of the present application, the storage locations of the present application may be arranged only at intervals along a height, or may be arranged only at intervals in the same horizontal plane.

[0079] 1 to 4, in this embodiment, the container unloading device includes a door frame and an unloading assembly that moves relative to the door frame along the X-, Y-, and Z-axes of a spatial coordinate system, where the vertical distance direction between the picking workspace and the rack is referred to as the Y-axis direction, the direction perpendicular to the Y-axis in a horizontal plane is referred to as the X-axis direction, and the direction perpendicular to the horizontal plane is referred to as the Z-axis direction. It may also be understood that the plane on which the X- and Y-axes are located is the horizontal plane, and the Z-axis is located within the vertical plane. Please refer to FIGS. 2 to 4 for further explanation to facilitate understanding of the relative positional relationships between the X-, Y-, and Z-axes.

[0080] Specifically, the door frame includes a base 40, a left support pillar 41, a right support pillar 42, and a cross beam 43, where the base 40 is fixedly installed within the operating plane where the workstation area and the rack stay area are located, the left support pillar 41 and the right support pillar 42 are parallel to each other, and the cross beam 43 is installed parallel to the base 40 and is fixedly connected to the left support pillar 41 and the right support pillar 42. In other words, these four members are connected in sequence to form a rectangular door frame structure.

[0081] The container loading / unloading device includes a movable support 44 located between the left support 41 and the right support 42 and movable relative to the base 40 and the cross beam 43 along the extension direction of the base 40 and the cross beam 43, i.e., the X-axis direction, and the loading / unloading assembly 45 is mounted on the movable support 44 and is controlled by a Z-axis drive mechanism to move along the extension direction of the movable support 44, thereby adjusting the displacement of the loading / unloading assembly 45 in the Z-axis direction relative to the rack.

[0082] The loading / unloading assembly 45 includes a base 450 that is attached to the movable support column 44 and moves along the Z-axis direction relative to the movable support column 44, and a loading / unloading member 451 that is controlled by a Y-axis drive mechanism and moves along the Y-axis direction relative to the base 450.

[0083] In some embodiments, the Y-axis drive mechanism may be a cylinder, the body of which is fixedly mounted on a base 450, and a loading / unloading member 451 is mounted on its piston rod. By controlling the flow direction of gas within the body of the cylinder, the piston rod can be driven to move the loading / unloading member 451 in a reciprocating manner along the Y-axis direction relative to the cylinder body.

[0084] When the warehouse storage system receives a picking order, the container unloading device determines the specific location (spatial coordinate location of the container) of the container containing the cargo included in this order on the rack 20 based on the database records of the warehouse storage system. It controls the unloading assembly 45 to move along the X-axis and Y-axis relative to the door frame until it is roughly aligned with the target container, and then controls the unloading member 451 of the unloading assembly 45 to move along the Y-axis relative to its base 450 until it grabs the target container.

[0085] More specifically, in this embodiment, the unloading member 451 is a chuck that communicates with a vacuum generator. When the vacuum generator is activated, the chuck generates a suction force to suck the material box and then return to the base.

[0086] When a loading / unloading assembly having such a structure is used, there is no need to leave a space between two adjacent material boxes on the rack 20 in advance for the insertion of a commonly used fork arm, and the material boxes can be arranged closely on the rack 20, making full use of the space in the rack 20 to accommodate the material boxes.

[0087] According to some other embodiments of the present application, the unloading assembly of the present application may include a push-pull unloading assembly, a knuckle unloading assembly, a fork unloading assembly, a robotic arm, and the like.

[0096] Additionally, in this embodiment, the warehouse storage system further includes an automated transport device configured to be used to transport racks to the rack docking area, the racks housing containers containing cargo.

[0097] It should be understood that the automated transport devices of the present application include load-bearing, lift-type, tow-type, and fork-type automated transport devices.

[0098] According to one embodiment of the present application, the present container unloading device includes a door frame and an unloading assembly that moves relative to the door frame along X and Y axes of a spatial coordinate system.

[0099] The unloading assembly moves along an X axis to select a target container and then moves along a Y axis to grab the target container.

[0100] It should be noted that for the mechanism for movement of the loading / unloading assembly relative to the door frame in the X and Y axes, please refer to the three-axis movement example described above.

[0101] According to one embodiment of the present application, the present container unloading device includes a door frame and an unloading assembly that moves relative to the door frame along Z and Y axes of a spatial coordinate system.

[0102] The unloading assembly moves along the Z axis to select a target container and then moves along the Y axis to grab the target container.

[0103] It should be noted that for the Z and Y axis movement mechanism of the loading / unloading assembly relative to the door frame, please refer to the three axis movement example described above.

[0104] According to some embodiments of the present application, the storage locations of the present multi-function area are configured to be used to store containers in which the demand frequency of cargo therein during a given time period exceeds a demand frequency threshold.

[0105] Here, the demand frequency within a specified time period is the number of times that this item is included in a picking order during a specified time period. In other words, if this item is included in both of two picking orders during a specified time period, this means that the demand frequency for this item during this specified time period is two times.

[0106] The demand frequency threshold is a predetermined reference value for determining whether the demand frequency of a particular item is high or low, and this reference value may be a specific numerical value or a numerical range. The demand frequency threshold depends on factors such as the weight of the item and the place of origin.

[0107] The predetermined time period may be a specific value or a range of values ​​that is preset, such as several hours in a day, a day, a week, a month, a season, or a year, etc. It is set by the warehouse storage system according to an actual use case, or set by an operator based on the actual picking workload.

[0108] For easier understanding, the working principle of the above warehouse storage system will be described in detail below based on two use cases. (Use Case 1)

[0109] The storage locations in the multi-function area are configured to be used to store containers for storing packages whose demand frequency within a predetermined time period is greater than a demand frequency threshold.

[0110] If the demand frequency of this item within a given time period is equal to the demand frequency threshold, it means that the demand frequency of this item is within a normal level. If the demand frequency of this item within a given time period is greater than the demand frequency threshold, it means that this item is a popular or best-selling item. Conversely, if the actual demand frequency of this item within a given time period is less than the demand frequency threshold, it means that this item is a leftover item.

[0111] When the warehouse storage system determines based on the demand frequency within a specified time period that the cargo stored in the container is a popular or best-selling item, i.e., the actual demand frequency of this cargo within a specified time period is greater than the demand frequency threshold, the container loading / unloading device of the warehouse storage system will grab this container from the rack in the rack docking area and transfer this container to the multi-function area for temporary storage.

[0112] Upon receiving a command (order) to pick the cargo in this container, the container unloading device transfers this container from the multi-function area to a picking workspace in the workstation area so that it can be picked by a worker or a picking robot.

[0113] After picking is completed, if there is still cargo remaining in the container, the container unloading device returns the container to the multi-function area and stores it temporarily, otherwise it returns the container directly to the empty container storage area.

[0114] In particular, the picking system can identify materials that are not currently needed but will be needed in a certain time. After the multi-function area is set up, the system can acquire more materials than are needed for the current sowing wall. That is, if the rack contains materials needed for the current sowing wall, as well as materials that will be used in a certain time, the container unloading device can remove the previously needed materials from the rack and temporarily store them in the multi-function area. When these materials are needed, the container unloading device can directly remove these materials or the containers containing these materials from the multi-function area and transport them to the picking position for picking, thereby accelerating the order completion speed and effectively reducing the number of rack transports by the automated transport device.

[0115] It should be noted that popular products may be stored directly in the multi-function area when they are received, or they may be removed from the warehouse storage area when they are picked and then stored directly in the multi-function area after the picking is complete. (Use Case 2)

[0116] The multi-function area is configured to be used to store a second container, and the second container is used to store packages having a next day demand frequency greater than a daily demand frequency threshold.

[0117] It should be noted that the daily demand frequency threshold is a specific value or a range of values ​​that is preset for the daily demand frequency of goods, and the daily demand frequency threshold depends on factors such as the type of goods and the season. For example, the daily demand frequency of ice cream in summer is higher than that in winter.

[0118] When the warehouse storage system determines in advance that the actual daily demand frequency of a cargo on the following day is greater than the daily demand frequency threshold value based on a reserved order or the actual daily demand frequency of the cargo, it calls an automatic transport device to transport the rack containing the container containing the cargo to the rack stay area, and a container loading / unloading device transfers the container from the rack to a multi-function area for temporary storage.

[0119] When the warehouse storage system receives a command to pick the goods in this container the next day, the container unloading device transfers this container from the multi-function area to a picking workspace for picking by a worker or a picking robot. After picking is complete, the container unloading device returns this container with any remaining goods to the multi-function area or returns the empty container directly to the empty container storage area.

[0120] According to some embodiments of the present application, the storage locations of the present multi-function areas are configured to be used to house containers storing items associated with designated cargo.

[0121] Here, the item related to the designated item may be a free gift for the designated item, which is an item given free of charge when purchasing the designated item. Of course, the item related to the designated item may also be a product that is discounted when ordered in the same order as the designated item.

[0122] The warehouse storage system calls the automatic transport device to transport the rack storing the prize to the rack docking area, and the container loading and unloading device transfers the container storing the prize from the rack in the rack docking area to the multi-function area for temporary storage. When the warehouse storage system receives a command to pick a designated item related to the prize, it calls the automatic transport device to transport the rack storing the designated item to the rack docking area, and the container unloading device transfers the container storing the designated item from the rack in the rack docking area to a picking work space in the workstation area, and then, or before this step, the container unloading device transfers the prize storage container from the multi-function area to the picking work space so that it can be picked by a worker or a picking robot.

[0123] After picking is completed, if the designated cargo still remains in the container, the container unloading device returns the container storing the designated cargo to the rack or returns the empty container directly to the empty container storage area, and if the prize still remains in the container, the container unloading device returns the container to the multi-function area or returns the empty container to the empty container storage area.

[0124] It should be noted that prizes may be stored directly in the multi-function area when they are received, or may be removed from the warehouse storage area when a popular product is being picked and then stored directly in the multi-function area after picking is complete.

[0125] According to one embodiment of the present application, the storage locations of the present multi-functional area are configured to be used to store a container, and the picking of the cargo in this container has already been completed and the container unloading device does not have time to transfer this container.

[0126] In detail, when a worker or a picking robot has already completed picking for one picking order and the container loading / unloading device is in operation and there is no time to transfer the picked container, the worker or the picking robot will transport the container to the multi-function area for temporary storage, and after the container loading / unloading device becomes idle, the worker or the picking robot will transfer the container to the rack, thereby preventing the picked container from being piled up in the picking work space and affecting the picking of subsequent picking orders, and ensuring that the picking work is carried out in an orderly and smooth manner.

[0127] According to one embodiment of the present application, the multi-function area of ​​the present application is configured to be used to store a container, and picking of the luggage in this container has already been completed, and the rack storing this container has not yet arrived at the rack docking area.

[0128] Specifically, for the sake of convenience, each container in a warehouse storage system is stored in a designated rack, and after a worker or a picking robot completes picking according to an order, the container generally needs to be returned to the designated rack.

[0129] However, due to reasons such as the automatic transport device being occupied during the actual picking work, the racks storing the picked containers have not yet reached the rack stay area, resulting in the problem of containers being piled up in the picking work space.

[0130] Based on this, in the warehouse storage system of the present application, when the rack storing the picked container has not yet arrived at the rack docking area, the worker, picking robot or container loading device will first temporarily store the container in the multi-function area, and after the rack for this container arrives, the container loading device will transfer the container to the rack, thereby preventing the picked containers from piling up in the picking work space and affecting the picking of subsequent picking orders, and ensuring that the picking work is carried out in an orderly and smooth manner.

[0131] According to one embodiment of the present application, the storage locations of the present application's multi-function area are configured to be used to store a container, and the picking of a package within this container has already been completed and this package has been hit in an order waiting to be picked.

[0132] In order to rationally arrange the workload of each picking work space in the warehouse storage system, the warehouse storage system periodically assigns picking orders to each picking work space, i.e., each picking work space is assigned multiple picking orders, which are lined up in order according to the assigned time and wait to be picked. Since a package in a picking order currently being picked in a picking work space may appear in a subsequent picking order, and this container stores packages that appear in multiple picking orders, the warehouse storage system needs to call the automated transport device multiple times.

[0133] Therefore, in the warehouse storage system of the present application, after picking is completed, it is checked whether the picked item matches any of the subsequent orders waiting to be picked.If the item matches, the worker, picking robot, or container loading device will first temporarily store the container in the multi-function area, and then, when the picking order that the item matches arrives, the container will be transported directly from the multi-function area.This eliminates the need to call the automatic transport device multiple times to transport the rack storing the container, reducing the number of times the automatic transport device needs to be called and improving picking efficiency.

[0134] According to one embodiment of the present application, the present container unloading device is configured to perform a loading and unloading operation.

[0135] For easier understanding, the cargo management principle of the above container loading / unloading device will be described in detail below based on two use cases. (Use Case 1)

[0136] When the container loading / unloading device is idle, the warehouse storage system calls an automatic transport device to transport the rack to the rack stay area, and based on the types of goods stored in the rack and the demand frequency of various goods in previous orders in a specified time period, the warehouse storage system adjusts the positions of different containers on the rack, for example, moving containers of goods with high demand frequency outside containers of goods with low demand frequency, thereby shortening the picking time and improving picking efficiency.

[0137] If the demand frequency of the cargo in the first container is greater than that of the cargo in the second container during a given time period, and the position of the second container on the rack is easier to access than that of the first container, The container unloading device unit is configured to move a second container from the rack to the multi-function area for temporary storage, transfer a first container from its current location to the original location of the second container, and transfer the second container from the multi-function area to the original location of the first container.

[0138] In detail, the warehouse storage system determines whether the demand frequency of the cargo in the rack is high or low during a given time period based on previous orders, and if the container of the cargo with a high demand frequency is located inside the container of the cargo with a low demand frequency, the container unloading device first transfers the container of the cargo with a low demand frequency from the rack to the multi-function area for temporary storage, then transfers the container of the cargo with a high demand frequency from the rack to the multi-function area for temporary storage, and then returns the container of the cargo with a low demand frequency from the multi-function area to the rack, and finally returns the container of the cargo with a high demand frequency from the multi-function area to the rack and positions it outside the container of the cargo with a low demand frequency, thereby making it easier to grab.

[0139] Alternatively, the container loading / unloading device adjusts containers of cargo with a high demand frequency to a lower position on the rack, and adjusts containers of cargo with a low demand frequency to a higher position on the rack.

[0140] Specifically, the warehouse storage system calls an automatic transport device to transport a rack to the rack docking area, and determines the demand frequency classes of various items on the rack based on previous orders. Based on this, the container loading / unloading device first transfers the containers of less frequently demanded items in the lower level of the rack to the multi-function area for temporary storage, then moves the containers of more frequently demanded items in the higher level of the rack to the lower level, and then returns the containers of less frequently demanded items temporarily stored in the multi-function area to the higher level of the rack, repeating this operation until all the more frequently demanded items on the rack are located below the containers of less frequently demanded items, thereby facilitating loading and unloading. (Use Case 2)

[0141] If the demand frequency of the cargo in the container during a given time period exceeds the demand frequency threshold, the container unloading device is configured to transfer the container from the current rack to a new rack dedicated to storing containers whose demand frequency during a given time period of the cargo exceeds the demand frequency threshold.

[0142] If the demand frequency of this package within a given time period is equal to the demand frequency threshold, it means that the demand frequency of this package is within a normal level. If the demand frequency of this package within a given time period is greater than the demand frequency threshold, it means that this package is a popular or best-selling product. Conversely, if the actual demand frequency of this package within a given time period is less than the demand frequency threshold, it means that this package is a leftover product.

[0143] When the warehouse storage system determines that the goods stored in the container are popular or best-selling goods based on the demand frequency within a predetermined time period, i.e., the actual demand frequency of the goods within a predetermined time period is greater than the demand frequency threshold, the container unloading device of the warehouse storage system will grab the container from the current rack and transfer the container to a new rack.

[0144] In this application, all containers of frequently requested items within a specified time period are stored in a new rack, and this rack is parked at a rack location. When a picking order requires picking of any of the items, the container is directly transferred from this rack to a picking work space, eliminating the need for the automated transport device to make multiple round trips between racks corresponding to each item, thereby reducing the number of transports by the automated transport device and improving picking efficiency.

[0145] After picking is completed, if there is still cargo remaining in the first container, the container unloading device returns the first container to the multi-function area for temporary storage, or conversely, returns the first container directly to the empty container storage area.

[0146] According to one embodiment of the present application, the present container unloading device is configured to be used to return empty containers to a multi-function area.

[0147] The empty containers are transferred from the container storage area to the multi-function area by a container loading / unloading device, or the warehouse storage system calls an automatic transport device to transfer a rack containing the empty containers to the rack docking area, and then the container loading / unloading device transfers the empty containers from the rack to the multi-function area for temporary storage.

[0148] When the warehouse storage system receives a command to load a full box or an external container supply shortage alert, the container unloading device transfers an empty container from the multi-function area to the picking workspace, so that a worker or picking robot can pick the load into the empty container.

[0149] It should be noted that loading the entire box means packing the container full of cargo and then storing it as a whole.

[0150] According to one embodiment of the present application, the present container unloading device is configured to be used to return empty containers to a rack for storing empty containers.

[0151] After the worker or picking robot has completed the picking, if the picked container is empty, the container unloading device returns the empty container to a rack for storing empty containers, and this rack may be staying in the rack staying area.

[0152] When the warehouse storage system receives a command to load a full box or an external container supply shortage alert, the container unloading device transfers an empty container from a rack storing the empty container to a picking workspace, whereby a worker or picking robot picks the load into the empty container.

[0153] The present invention further provides a method for controlling a warehouse storage system, which is specifically the warehouse storage system described above, and the method for controlling the warehouse storage system includes: The method includes the major step of a container unloading device transferring containers that meet the predetermined attributes between a workstation area, a rack dock area, and a multi-function area based on the predetermined attributes.

[0154] For easier understanding, the specific control logic of the control method of the present invention will be described in detail below with reference to four examples, with reference to FIGS. (Example 1 of control method)

[0155] Referring to FIG. 5, in this embodiment, the control method for the warehouse storage system includes the following steps S100, S200 and S300.

[0156] In S100, if the demand frequency of the container's cargo in a predetermined time period exceeds a demand frequency threshold, a container unloading device transfers the container from a rack in the rack stay area to a multi-function area.

[0157] Here, the demand frequency within a specified time period is the number of times that this item is included in a picking order during a specified time period. In other words, if this item is included in both of two picking orders during a specified time period, this means that the demand frequency for this item during this specified time period is two times.

[0158] The predetermined time period may be a specific value or a range of values ​​that is preset, such as several hours in a day, a day, a week, a month, a season, or a year, etc. It is set by the warehouse storage system according to an actual use case, or set by an operator based on the actual picking workload.

[0159] Upon receiving a command to pick the shipment, the container unloading device transfers the container from the multi-function area to the picking workspace.

[0160] If the demand frequency of this package within a given time period is equal to the demand frequency threshold, it means that the demand frequency of this package is within a normal level. If the demand frequency of this package within a given time period is greater than the demand frequency threshold, it means that this package is a popular or best-selling product. Conversely, if the actual demand frequency of this package within a given time period is less than the demand frequency threshold, it means that this package is a leftover product.

[0161] When the warehouse storage system determines based on the demand frequency within a specified time period that the cargo stored in the container is a popular or best-selling item, i.e., the actual demand frequency of this cargo within a specified time period is greater than the demand frequency threshold, the container loading / unloading device of the warehouse storage system will grab this container from the rack in the rack docking area and transfer this container to the multi-function area for temporary storage.

[0162] In S200, when a command to pick the cargo in this container is received, the container unloading device transfers this container from the multi-function area to a picking workspace in the workstation area for picking by a worker or picking robot.

[0163] Of course, in some other embodiments, the picker may not utilize a container unloading device and may transfer the container directly from the multi-function area to the picking workspace in the workstation area.

[0164] In S300, after picking is completed, the container unloading device returns the container with remaining cargo to the multi-function area for temporary storage, or directly returns the empty container to the empty material box storage area.

[0165] In particular, the picking system can identify materials that are not currently needed but will be needed in a certain time. After the multi-function area is set up, the system can acquire more materials than are needed for the current sowing wall. That is, if the rack contains materials needed for the current sowing wall, as well as materials that will be used in a certain time, the container unloading device can remove the previously needed materials from the rack and temporarily store them in the multi-function area. When these materials are needed, the container unloading device can directly remove these materials or the containers containing these materials from the multi-function area and transport them to the picking position for picking, thereby accelerating the order completion speed and effectively reducing the number of rack transports by the automated transport device.

[0166] It should be noted that popular products may be stored directly in the multi-function area when they are received, or they may be removed from the warehouse storage area when they are picked and then stored directly in the multi-function area after the picking is complete. (Control Method Example 2)

[0167] Referring to FIG. 6, in this embodiment, the control method for the warehouse storage system includes the following steps S101, S201 and S301.

[0168] In S101, if the daily demand frequency of the cargo in the container on the next day is greater than the daily demand frequency threshold, the container loading / unloading device transfers the container from the rack in the rack stay area to the multi-function area for temporary storage.

[0169] It should be noted that the daily demand frequency threshold is a specific value or a range of values ​​that is preset for the daily demand frequency of goods, and the daily demand frequency threshold depends on factors such as the type of goods and the season. For example, the daily demand frequency of ice cream in summer is higher than that in winter.

[0170] In detail, in one embodiment, when the warehouse storage system receives a reservation order for the next day, it compares the magnitude relationship between the daily demand frequency of the target cargo in the reservation order for the next day and the daily demand frequency threshold, and if the target cargo is contained in a container and the daily demand frequency of the target cargo in the reservation order for the next day is greater than the daily demand frequency threshold, the warehouse storage system calls an automatic transport device to transport the rack storing the container to the rack docking area, and the container loading and unloading device transfers the container from the rack in the rack docking area to the multi-function area for temporary storage.

[0171] In another embodiment, if the warehouse storage system determines in advance that the daily demand frequency of the target cargo stored in the container on the following day will be greater than the daily demand frequency threshold of the target cargo, based on the actual demand frequency of the target cargo within that day, the warehouse storage system calls an automatic transport device to transport the rack storing the container to the rack docking area, and a container loading / unloading device transfers the container from the rack in the rack docking area to a multi-function area for temporary storage.

[0172] For example, for cargo such as fruits and vegetables whose demand frequency is seasonal, the warehouse storage system finds that the daily demand frequency for heart-shaped apples on October 10th at the end of autumn far exceeded the preset daily demand frequency threshold for this cargo. Based on this, the warehouse storage system determines in advance that the daily demand frequency for heart-shaped apples the next day will also exceed the daily demand frequency threshold. The warehouse storage system calls an automatic transport device to transport the rack containing the heart-shaped apples to the rack docking area, and a container loading / unloading device transfers the container from the rack in the rack docking area to the multi-function area for temporary storage, and stores the target cargo, the heart-shaped apples, in this container.

[0173] In S201, when the warehouse storage system receives a command to pick the cargo in this container the next day, the container unloading device transfers this container from the multi-function area to a picking workspace in the workstation area for picking by a worker or a picking robot.

[0174] In S301, after picking is completed, the container unloading device returns the container with remaining cargo to the multi-function area for temporary storage, or directly returns the empty container to the empty material box storage area. (Control Method Example 3)

[0175] Referring to FIG. 7, in this embodiment, the control method for the warehouse storage system includes the following steps S102, S202, S203 and S302.

[0176] In S102, when the items related to the designated cargo are stored in the first container on the rack, the container loading / unloading device transfers the first container from the rack in the rack stay area to the multi-function area for temporary storage.

[0177] Here, the item related to the designated item may be a free gift for the designated item, which is an item given free of charge when purchasing the designated item. Of course, the item related to the designated item may also be a product that is discounted when ordered in the same order as the designated item.

[0178] Before step S102, this control method further includes the step of calling an automatic transport device to transport the rack storing the first container to the rack stay area.

[0179] At S202, when the warehouse storage system receives a command to pick the designated shipment, the container unloading device transfers the first container from the multi-function area to the picking workspace for picking by a worker or picking robot.

[0180] Before or after step S202, the control method further includes step S203, in which the warehouse storage system calls an automatic transport device to transport the rack storing the designated cargo to the rack stay area, and the container loading and unloading device transfers a second container storing the designated cargo on the rack from the rack in the rack stay area to a picking work space in the workstation area.

[0181] In S302, after picking is completed, the container unloading device returns the first container in which the items related to the designated cargo still remain to the multi-function area for temporary storage, or directly returns the empty first container to the empty material box storage area, and returns the second container in which the designated cargo still remains to the rack, or directly returns the empty second container to the empty material box storage area.

[0182] It should be noted that items related to designated cargo may be stored directly in the multi-function area when they are received, or when a popular product is to be picked, they may be removed from the warehouse storage area and stored directly in the multi-function area after picking is complete. (Control Method Example 4)

[0183] In this embodiment, the control method for the warehouse storage system includes: When the container unloading device is idle, performing a packing operation is included.

[0184] When the container loading / unloading device is idle, the warehouse storage system calls an automatic transport device to transport the rack to the rack stay area, and based on the types of goods stored in the rack and the demand frequency of various goods in previous orders, the warehouse storage system adjusts the positions of different containers on the rack, for example, moving containers containing goods with high demand frequencies outside containers containing goods with low demand frequencies, thereby shortening the picking time and improving picking efficiency.

[0185] In detail, the warehouse storage system determines whether the cargo in the rack has a high or low demand frequency based on previous orders, and if the container of the cargo with a high demand frequency is located inside the container of the cargo with a low demand frequency, the container loading / unloading device first transfers the container of the cargo with a low demand frequency from the rack to the multi-function area for temporary storage, then transfers the container of the cargo with a high demand frequency from the rack to the multi-function area for temporary storage, and then returns the container of the cargo with a low demand frequency from the multi-function area to the rack, and finally returns the container of the cargo with a high demand frequency from the multi-function area to the rack and positions it outside the container of the cargo with a low demand frequency, thereby making it easier to grab.

[0186] Alternatively, the container loading / unloading device adjusts containers of cargo with a high demand frequency to a lower position on the rack, and adjusts containers of cargo with a low demand frequency to a higher position on the rack.

[0187] Specifically, the warehouse storage system calls an automatic transport device to transport a rack to the rack docking area, and determines the demand frequency classes of various items on the rack based on previous orders. Based on this, the container loading / unloading device first transfers the containers of less frequently demanded items in the lower level of the rack to the multi-function area for temporary storage, then moves the containers of more frequently demanded items in the higher level of the rack to the lower level, and then returns the containers temporarily stored in the multi-function area to the higher level of the rack, repeating this operation until all the more frequently demanded items on the rack are located below the less frequently demanded items, thereby facilitating loading and unloading. (Control Method Example 5)

[0188] In this embodiment, the control method for a warehouse storage system includes the following steps.

[0189] Empty containers are stored in the multi-function area.

[0190] It is to be noted that empty containers may be stored in a rack in advance, the warehouse storage system may call an automated transport device to transport the rack to the rack docking area, and then a container loading / unloading device may transfer the empty container from the rack to a multi-function area for temporary storage.

[0191] When the warehouse storage system receives a command to load a full box or an external container supply shortage alert, the container unloading device transfers an empty container from the multi-function area to the picking workspace, so that a worker or picking robot can pick the load into the empty container.

[0192] It should be noted that loading a whole box means that the container must be fully packed and then sold as a whole. (Control Method Example 6)

[0193] In this embodiment, the control method for the warehouse storage system includes: After the picking of the packages in the container is completed, determining whether the package has been picked in the order waiting to be picked; When a package is found in the order waiting to be picked, the container unloading device transfers the container from the picking workspace to a multi-function area for temporary storage; and upon receiving a command to pick the order awaiting picking that has been hit with cargo, a container unloading device transfers the container from the multi-function area to a picking workspace.

[0194] It should be noted that if the demand frequency of the corresponding parcel waiting to be picked in the container does not reach the demand frequency threshold, but order picking is still required in the future, the container is directly stored in the multi-function area to avoid round-trip transportation and improve overall work efficiency. It can be understood that if the demand frequency of the picked parcel is not higher than the demand frequency threshold, the container unloading device will directly transfer the container of the parcel from the picking workspace to its original position on the original rack or another empty position. If the storage position of the container on the original rack needs to be adjusted or the storage rack needs to be changed, it can be temporarily stored in the multi-function area as needed, and then placed in a corresponding new storage position by the container unloading device. Alternatively, it can be directly placed in a new storage position by the container unloading device. (Warehouse Storage System Example 2)

[0195] In another embodiment of the present disclosure, a warehouse storage system of the present disclosure includes a workstation area, a rack docking area, a multi-function area, and a container loading / unloading device, wherein the workstation area includes a picking workspace, the rack docking area is arranged to be used for docking of racks, the multi-function area is located above the picking workspace and configured to be used for storing containers transferred from the picking workspace or the racks, and the container unloading device is configured to transfer containers between the workstation area, the rack docking area, and the multi-function area.

[0196] It is important to note that the racks in the warehouse storage system of the present invention do not only include racks in the traditional sense, but also include trays, material storage shelves, or other types of cargo storage devices that can be moved between different areas of the warehouse by automated transport devices or other mobile devices. On the other hand, the automated transport device for transporting racks in the present invention is not an automated transport device that transports traditional racks, but a robot that can transport goods placement devices such as racks, trays, or material storage shelves.

[0197] This warehouse storage system can temporarily store containers that meet predetermined conditions in a multi-function area in advance based on information such as the target delivery volume of the ordered cargo. When a picking order related to these predetermined conditions is received, there is no need to call an automated transport device to transport a rack storing the corresponding container. Instead, the container unloading device simply transfers the corresponding container from the multi-function area to a picking workspace, and after picking is complete, the container unloading device returns the container to the multi-function area, thereby reducing the workload of the automated transport device. Furthermore, because the multi-function area is located above the picking workspace, the container unloading device can quickly transfer the container, significantly improving picking efficiency.

[0198] For easier understanding, the specific structure and operation principle of this warehouse storage system will be described in detail below by taking one specific embodiment as an example with reference to Figures 1 to 4. It should be noted that ordinal numbers such as "first", "second", etc. will be used to distinguish between containers for clear description, and it should be understood that these ordinal numbers do not limit the scope of protection of the present invention.

[0199] 1, in this embodiment, the warehouse storage system includes a workstation area, a rack area, a multi-function area, and a container loading / unloading device. For a clearer understanding of the specific structure of the warehouse storage system, please also refer to FIGS. 2 to 4.

[0200] Here, the workstation area includes a picking workspace configured to be used to store a container so that a worker or picking robot can pick a parcel from the container that meets the order requirements and then place the parcel on an automated transport device or conveyor belt.

[0201] The picking workspace includes a first support frame and a first guide mechanism provided on the first support frame, the first guide mechanism being configured to be used to assist the container loading / unloading device in loading and unloading the container.

[0202] In detail, the first support frame includes a first bracket 10, a first left side upright plate 11, a first right side upright plate 12 and a first intermediate upright plate 13, wherein the first left side upright plate 11, the first right side upright plate 12 and the first intermediate upright plate 13 are sequentially mounted on the first bracket 10 in parallel and spaced apart relation.

[0203] The first guide mechanism includes a plurality of first rollers 14, some of which are rotatably arranged in parallel with each other at intervals between the first left upright plate 11 and the first intermediate upright plate 13, and other of which are rotatably arranged in parallel with each other at intervals between the first right upright plate 12 and the first intermediate upright plate 13. The function of the first bracket 10 is to raise the first left upright plate 11, the first right upright plate 12, and the first intermediate upright plate 13 to a predetermined height from the floor so that a worker or a picking robot can easily pick packages.

[0204] After the container loading / unloading device places the container in the picking workspace, if it is considered that it is difficult for a worker or a picking robot to perform a picking operation at the current location of the container, the rolling characteristics of the first guide mechanism may be used to push the container from its current location to a position where it is easier to operate with a small force.

[0205] The rack stay area is located near the picking work space, and can accommodate at least two racks 20, thereby enabling the warehouse storage system to quickly pick a greater variety or quantity of items per unit time.

[0206] The multi-function area includes a plurality of storage locations, each storage location including a second support frame and a second guide mechanism provided on the second support frame, the second guide mechanism configured to be used to assist a container loading / unloading device in loading and unloading containers.

[0207] In detail, the second support frame includes a second bracket 30, a second left side upright plate 31, and a second right side upright plate 32, where the second left side upright plate 31 and the second right side upright plate 32 are mounted on the second bracket 30 in parallel with and spaced apart from each other.

[0208] The second guide mechanism includes a plurality of second rollers 33 provided between a second left standing plate 31 and a second right standing plate 32 in parallel with each other and rotatably spaced apart from each other.

[0209] The storage locations may be fixed to the fixed wall of the warehouse by the second bracket 30 or to the picking workspace by the auxiliary bracket, ensuring that the multi-function area is located above the picking workspace and fully utilizing the available space above the picking workspace in the warehouse. Each storage location in this embodiment is used to store containers transferred by at least one container loading / unloading device. It should be further noted that the above structure is merely one implementation of the storage location, and that other structures may be adopted for the storage location as long as they can store containers, and each storage location may be configured to store only one shipping box.

[0210] In order to store more material boxes in the multi-function area, in this embodiment, referring to Figure 1, the multi-function area includes a plurality of storage locations, some of which are arranged vertically at intervals, and some of which are arranged horizontally at intervals. It should be understood that the specific number of storage locations depends on the size of the space above the picking workspace, and those skilled in the art can select the appropriate number and arrangement method according to the actual situation.

[0211] Of course, in some other embodiments, the storage locations are simply spaced apart vertically, or simply spaced apart horizontally.

[0212] The container unloading device includes a door frame and an unloading assembly that moves relative to the door frame along the X-, Y-, and Z-axes of a spatial coordinate system, where the vertical distance direction between the picking workspace and the rack is referred to as the Y-axis direction, the direction perpendicular to the Y-axis in a horizontal plane is referred to as the X-axis direction, and the direction perpendicular to the horizontal plane is referred to as the Z-axis direction. It may also be understood that the plane on which the X- and Y-axes are located is the horizontal plane, and the Z-axis is located in a vertical plane. Please refer to Figures 2 to 4 for a clearer understanding of the relative positional relationships between the X-, Y-, and Z-axes.

[0213] Specifically, the door frame includes a base 40, a left support pillar 41, a right support pillar 42, and a cross beam 43, where the base 40 is fixedly installed within the operating plane where the workstation area and the rack stay area are located, the left support pillar 41 and the right support pillar 42 are parallel to each other, and the cross beam 43 is installed parallel to the base 40 and is fixedly connected to the left support pillar 41 and the right support pillar 42. In other words, these four members are connected in sequence to form a rectangular door frame structure.

[0214] The container loading / unloading device includes a movable support 44 located between the left support 41 and the right support 42 and movable relative to the base 40 and the cross beam 43 along the extension direction of the base 40 and the cross beam 43, i.e., the X-axis direction, and the loading / unloading assembly 45 is mounted on the movable support 44 and is controlled by a Z-axis drive mechanism to move along the extension direction of the movable support 44, thereby adjusting the displacement of the loading / unloading assembly 45 in the Z-axis direction relative to the rack.

[0215] The loading / unloading assembly 45 includes a base 450 that is attached to the movable support column 44 and moves along the Z-axis direction relative to the movable support column 44, and a loading / unloading member 451 that is controlled by a Y-axis drive mechanism and moves along the Y-axis direction relative to the base 450.

[0216] In some embodiments, the Y-axis drive mechanism may be a cylinder, the body of which is fixedly mounted on a base 450, and a loading / unloading member 451 is mounted on its piston rod. By controlling the flow direction of gas within the body of the cylinder, the piston rod can be driven to move the loading / unloading member 451 in a reciprocating manner along the Y-axis direction relative to the cylinder body.

[0217] When the warehouse storage system receives a picking order, the container unloading device determines the specific location (spatial coordinate location of the material box) of the target container containing the cargo included in this order on the rack 20 based on the database record of the warehouse storage system, controls the unloading assembly 45 to move along the X-axis and Y-axis relative to the door frame until it is roughly aligned with the target container, and then controls the unloading member 451 of the unloading assembly 45 to move along the Y-axis relative to its base 450 until it grabs the target container.

[0218] More specifically, in this embodiment, the unloading member 451 is a chuck that communicates with a vacuum generator. When the vacuum generator is activated, the chuck generates a suction force to suck the material box and then return to the base.

[0219] When a loading / unloading assembly having such a structure is used, there is no need to leave a space between two adjacent material boxes on the rack 20 in advance for the insertion of a commonly used fork arm, and the material boxes can be arranged closely on the rack 20, making full use of the space in the rack 20 to accommodate the material boxes.

[0220] In addition, in some embodiments, the X-axis drive mechanism of the container unloading device may include an X-axis drive motor and an X-axis ball screw nut transmission mechanism, wherein the ball screw of the X-axis ball screw nut transmission mechanism is rotatably connected to the base 40 or the cross beam 43, and the nut block threaded thereto is fixedly connected to the movable support column 44, and the X-axis drive motor is used to drive the ball screw to rotate relative to the base 40 or the cross beam 43, so that the nut block can move the movable support column 44 along the X-axis in conjunction with the movable support column 44 to adjust the movement of the unloading assembly 45 along the X-axis direction relative to the door frame.

[0221] In some other embodiments, the X-axis drive mechanism of the container unloading device may include an X-axis drive motor and an X-axis rack-and-pinion transmission mechanism, wherein the pinion of the X-axis rack-and-pinion transmission mechanism is rotatably connected to the movable column 44, and the rack meshing therewith is fixedly connected to the base 40 or the cross beam 43 and extends along the X-axis direction, and the X-axis drive motor is used to drive the pinion to rotate relative to the movable column 44, so that the pinion can move the movable column 44 in conjunction with the movable column 44 along the extension direction of the rack, thereby adjusting the movement of the unloading assembly 45 along the X-axis direction relative to the door frame.

[0222] Furthermore, in this embodiment, the container loading / unloading device further includes an X-axis guide mechanism that is arranged to guide the movable support 44 to move along the X-axis direction relative to the door frame, ensuring the movement stability of the container loading / unloading device.

[0223] In detail, the X-axis guide mechanism includes an X-axis linear guide rail, which includes a linear rail extending along the X-axis and provided on the base 40 or cross beam 43 of the door frame, and a slider slidably connected to the linear rail, and the movable support 44 is provided on the slider and slides in the X-axis direction along the linear rail along with the slider.

[0224] In some embodiments, the Z-axis drive mechanism of the container unloading device may include a Z-axis drive motor and a Z-axis ball screw nut transmission mechanism, wherein the ball screw of the Z-axis ball screw nut transmission mechanism is rotatably connected to the movable support 44, and the nut block threaded thereto is fixedly connected to the base 450 of the unloading assembly 45, and the Z-axis drive motor is used to drive the Z-axis ball screw to rotate relative to the movable support 44, and thus the nut block can move the unloading assembly 45 along the Z-axis in conjunction with the unloading assembly 45 to adjust the movement of the unloading assembly 45 along the Z-axis direction relative to the door frame.

[0225] In some other embodiments, the Z-axis drive mechanism of the container unloading device may include a Z-axis drive motor and a Z-axis rack-and-pinion transmission mechanism, wherein the pinion of the Z-axis rack-and-pinion transmission mechanism is rotatably connected to the base 450 of the unloading assembly 45, the mating rack is fixedly connected to the movable support column 44 and extends along the Z-axis direction, and the Z-axis drive motor is used to drive the pinion to rotate relative to the movable support column 44, such that the pinion moves the unloading assembly 45 in conjunction with the extension direction of the rack to coordinate the movement of the unloading assembly 45 along the Z-axis direction relative to the door frame.

[0226] Similarly, in this embodiment, the container loading and unloading device further includes a Z-axis guide mechanism arranged to guide the loading and unloading assembly 45 for movement along the Z-axis direction relative to the movable support 44, ensuring movement stability of the container loading and unloading device.

[0227] In detail, the Z-axis guide mechanism includes a Z-axis linear guide rail, which includes a linear rail extending along the Z-axis and attached to the movable support 44, and a slider slidably connected to the linear rail, and the base 450 of the loading / unloading assembly 45 is attached to the slider and slides in the Z-axis direction along the linear rail along with the slider.

[0228] Additionally, in this embodiment, the warehouse storage system further includes an automated transport device configured to be used to transport racks to the rack docking area, the racks housing containers containing cargo.

[0229] For easier understanding, the working principle of the above warehouse storage system will be described in detail below based on several use cases. (Use Case 1)

[0230] The multi-functional area is configured to be used to store a first container, and the first container is used to store cargo having a first outgoing volume within a predetermined time period that is greater than a first outgoing volume threshold.

[0231] Here, the specified time period is longer than one day, i.e., the specified time period is one week, one month, one season, or one year, etc., and the first shipping volume threshold is a specific numerical value or numerical range that is preset based on one year shipping volume, one season shipping volume, one month shipping volume, one week shipping volume, etc.

[0232] If the actual first shipment volume of this package within a specified time period is equal to the first shipment volume threshold, it means that the first shipment volume of this package is within a normal level. If the actual first shipment volume of this package within a specified time period is greater than the first shipment volume threshold, it means that this package is a popular or best-selling product. Conversely, if the actual first shipment volume of this package within a specified time period is less than the first shipment volume threshold, it means that this package is a leftover product.

[0233] When the warehouse storage system determines based on the outgoing volume within a specified time period that the cargo stored in the first container is a popular or best-selling item, i.e., the actual first outgoing volume of this cargo within the specified time period is greater than the first outgoing volume threshold, the container loading / unloading device of the warehouse storage system grabs the first container from the rack in the rack stay area and transfers the first container to the multi-function area for temporary storage.

[0234] Upon receiving a command (order) to pick the cargo in the first container, the container unloading device transfers the first container from the multi-function area to a picking workspace in the workstation area for picking by a worker or picking robot.

[0235] After picking is completed, if there is still cargo remaining in the first container, the container unloading device returns the first container to the multi-function area for temporary storage, and otherwise returns the first container directly to the empty material box storage area.

[0236] In particular, the picking system can identify materials that are not currently needed but will be needed in a certain time. After the multi-function area is set up, the system can acquire more materials than are needed for the current sowing wall. That is, if the rack contains materials needed for the current sowing wall, as well as materials that will be used in a certain time, the container unloading device can remove the previously needed materials from the rack and temporarily store them in the multi-function area. When these materials are needed, the container unloading device can directly remove these materials or the containers containing these materials from the multi-function area and transport them to the picking position for picking, thereby accelerating the order completion speed and effectively reducing the number of rack transports by the automated transport device.

[0237] It should be noted that popular products may be stored directly in the multi-function area when they are received, or they may be removed from the warehouse storage area when they are picked and then stored directly in the multi-function area after the picking is complete.

[0238] In other words, popular and best-selling items have a higher hit probability, and when these items need to be used in the picking workspace, there is no need to call up the automatic transport device and rack. The container loading and unloading mechanism can directly unload the container in this multi-function area and place it in the picking workspace for picking, which greatly improves picking efficiency, accelerates the order completion speed, and effectively reduces the number of rack transports by the automatic transport device. (Use Case 2)

[0239] The multi-functional area is configured to be used to store a second container, and the second container is used to store parcels whose daily output volume for the next day is greater than a daily output volume threshold.

[0240] It should be noted that the daily shipping volume threshold is a specific value or a range of values ​​that is preset for the amount of cargo shipped in a day. The daily shipping volume threshold depends on factors such as the type of cargo and the season. For example, the daily shipping volume of ice cream in summer is higher than the daily shipping volume in winter.

[0241] When the warehouse storage system determines in advance that the actual daily shipping volume of the cargo on the following day is greater than the daily shipping volume threshold based on a reserved order or the actual daily shipping volume of the cargo on that day, it calls an automatic transport device to transport the rack containing the container containing the cargo to the rack stay area, and the container loading / unloading device transfers the container from the rack to a multi-function area for temporary storage.

[0242] When the warehouse storage system receives a command to pick the cargo in the second container the next day, the container unloading device transfers the second container from the multi-function area to the picking workspace so that it can be picked by a worker or a picking robot. After picking is complete, the container unloading device returns the second container that still has cargo remaining to the multi-function area, or returns the empty second container directly to the empty container storage area. (Use Case 3)

[0243] The multi-functional area is configured to be used to store a third container, and the third container is used to store items related to the designated cargo. Here, the items related to the designated cargo may be a gift for the designated cargo, which is an item given free of charge when purchasing the designated cargo. Of course, the items related to the designated cargo may also be a product that is discounted when ordered in the same order as the designated item.

[0244] The warehouse storage system calls the automatic transport device to transport the rack storing the prize to the rack docking area, and the container loading and unloading device transfers the third container storing the prize from the rack in the rack docking area to the multi-function area for temporary storage. When the warehouse storage system receives a command to pick a designated item related to the prize, it calls the automatic transport device to transport the rack storing the designated item to the rack docking area, and the container unloading device transfers the fourth container storing the designated item from the rack in the rack docking area to a picking workspace in the workstation area, and then, or before this step, the container unloading device transfers the third container storing the prize from the multi-function area to the picking workspace to be picked by a worker or a picking robot.

[0245] After picking is completed, if the designated cargo still remains in the fourth container, the container unloading device returns the fourth container storing the designated cargo to the rack or returns the empty fourth container directly to the empty container storage area, and if the prize still remains in the third container, the container unloading device returns the third container to the multi-function area or returns the empty third container to the empty container storage area.

[0246] It should be noted that prizes may be stored directly in the multi-function area when they are received, or may be removed from the warehouse storage area when a popular product is being picked and then stored directly in the multi-function area after picking is complete. (Use Case 4)

[0247] The container unloading device is configured to adjust the positions of different containers on the rack by means of a multi-function area at leisure.

[0248] When the container loading / unloading device is idle, the warehouse storage system calls an automatic transport device to transport the rack to the rack stay area, and based on the types of goods stored in the rack and the output volume of various goods in previous orders, the warehouse storage system adjusts the positions of different containers on the rack, for example, moving the fifth container, which stores goods with a high output volume, outside the sixth container, which stores goods with a low output volume, thereby shortening the picking time and improving picking efficiency.

[0249] In detail, the warehouse storage system determines whether the quantity of goods to be shipped on the rack is high or low based on previous orders. If the fifth container of the goods with a high quantity of goods to be shipped is located inside the sixth container of the goods with a low quantity of goods to be shipped, the container loading / unloading device will first transfer the sixth container of the goods with a low quantity of goods to the rack to the multi-functional area for temporary storage, then transfer the fifth container of the goods with a high quantity of goods to the rack to the multi-functional area for temporary storage, and then return the sixth container of the goods with a low quantity of goods to the rack from the multi-functional area, and finally return the sixth container of the goods with a high quantity of goods to the rack from the multi-functional area and position it outside the fifth container of the goods with a low quantity of goods to be shipped, thereby making it easier to grab.

[0250] Alternatively, the container loading / unloading device adjusts the fifth container of the cargo with a high outgoing volume on the rack to a low position on the rack, and adjusts the sixth container of the cargo with a low outgoing volume on the rack to a high position on the rack.

[0251] Specifically, the warehouse storage system calls an automatic transport device to transport a rack to the rack docking area, and determines the delivery volume classes of various items on this rack based on previous orders. Based on this, the container loading / unloading device first transfers the sixth container of the item with a low delivery volume in the low-level position of the rack to the multi-function area for temporary storage, then moves the fifth container of the item with a high delivery volume in the high-level position of the rack to the low-level position, and then returns the sixth container temporarily stored in the multi-function area to the high-level position on the rack, repeating this operation until all the items with a high delivery volume on the rack are located below the items with a low delivery volume, thereby facilitating loading and unloading.

[0252] Furthermore, when the container unloading device is idle, if the warehouse storage system can receive the order contents for the next day in advance, the system can send a command to control the automatic transport device to transport the containers related to the next day's orders from the storage area to the workstation, and the container unloading device can transfer the containers required for the next day's orders to one or more specific racks for storage. In the process of transferring the containers to one or more specific racks, the container unloading device can first temporarily store them in the multi-function area, and the one or more specific racks can be used to centrally store the containers related to the next day's orders. After collecting the containers on the one or more specific racks, the automatic transport device can correspondingly transport them to a storage area near the workstation area or close to the workstation, which can greatly improve the rack hit rate for the next day.

[0253] In other words, if the warehouse storage system can receive the next day's order content in advance or predict it based on the order, the container loading and unloading device can automatically complete the luggage sorting between racks during idle time, that is, containers that need to be shipped out the next day can be concentrated and stored in several racks, greatly improving the rack hit rate for the next day and thereby effectively reducing the number of transports required by the automatic transport device. Conventional means only support one pick-up and one load-up during automatic luggage sorting, which makes the luggage sorting speed slow. After the functional area is expanded, multiple pick-up and multiple load-up during luggage sorting becomes possible, greatly improving the efficiency of luggage sorting.

[0254] Furthermore, this warehouse storage system is configured to simultaneously utilize this multi-function area during the picking process to complete the arrangement of goods between racks.

[0255] In detail, when a manual picking operation is performed and the container loading / unloading device is idle at this time, the multi-function area can be used to complete the luggage arrangement between racks, that is, the previously hit containers can be concentrated and stored in some designated racks, thereby improving the rack hit rate of subsequent picking and reducing the number of transfers by the automatic transport device. (Use Case 5)

[0256] The multi-function area is configured to be used to store empty containers.

[0257] The empty containers are transferred from the container storage area to the multi-function area by a container loading / unloading device, or the warehouse storage system calls an automatic transport device to transfer the rack storing the empty containers to the rack docking area, and the container loading / unloading device then transfers the empty containers from the rack to the multi-function area for temporary storage.

[0258] When the warehouse storage system receives a command to load a full box or an external container supply shortage alert, the container unloading device transfers an empty container from the multi-function area to the picking workspace, so that a worker or picking robot can pick the load into the empty container.

[0259] It should be noted that loading a whole box means that the container must be fully packed and then sold as a whole. (Use Case 6)

[0260] The multi-function area is configured to open directly to a picking position.

[0261] Based on this, operators can directly pick up luggage from the multi-function area, thereby reducing the number of transports by the automated transport device, and in extreme cases, directly reducing the operation of the container loading / unloading device, thereby improving overall efficiency. (Use Case 7)

[0262] The multi-function area may be configured to be located above the picking workspace, or below the picking workspace, or may be configured as a movable rack that can be transported by an automated transport device, and this movable rack may be located behind the workstation and perform the above-mentioned temporary storage function. (Use Case 8)

[0263] The multifunctional area is configured as a special storage location.

[0264] In particular, the multi-function area can store special relatively tall containers, for example containers that cannot be loaded onto racks. (Use Case 9)

[0265] The multi-function area is configured to adjust the receiving sequence.

[0266] In detail, the warehouse storage system first places all or most of the incoming containers in a multi-function area, and then places these containers in the multi-function area in the target storage positions of the racks specified by the container loading / unloading device according to the order of the containers in the incoming order, thereby reducing the number of container transports by the automatic transport device and improving the efficiency of warehousing. (Use Case 10)

[0267] The multi-function area is configured to adjust the order of the bins.

[0268] In detail, the warehouse storage system first places all or most of the loading containers in a multi-function area, and then places these containers in the multi-function area in the target storage positions of the racks designated by the container loading / unloading device according to the order of the containers in the loading order, thereby reducing the number of container transports by the automatic transport device and improving loading efficiency.

[0269] The present invention further provides a method for controlling a warehouse storage system, which is specifically the above-mentioned warehouse storage system, and the method for controlling the warehouse storage system includes: The method includes the major step of a container unloading device transferring containers that meet the predetermined attributes between a workstation area, a rack dock area, and a multi-function area based on the predetermined attributes.

[0270] For easier understanding, the specific control logic of the control method of the present invention will be described in detail below with reference to four examples, with reference to FIGS. (Control Method Example 7)

[0271] Referring to FIG. 8, in this embodiment, the control method for a warehouse storage system includes the following steps S100, S200 and S300.

[0272] In S100, if the first outgoing quantity of cargo in the first container during the predetermined time period is greater than the first outgoing quantity threshold, the container loading / unloading device transfers the first container from the rack in the rack stay area to the multi-function area, and the predetermined time period is greater than one day.

[0273] Here, the specified time period is one week, one month, one season, or one year, etc., and the first shipping volume threshold is a specific numerical value or numerical range that is preset based on one year shipping volume, one season shipping volume, one month shipping volume, one week shipping volume, etc.

[0274] If the actual first shipment volume of this package within a specified time period is equal to the first shipment volume threshold, it means that the first shipment volume of this package is within a normal level. If the actual first shipment volume of this package within a specified time period is greater than the first shipment volume threshold, it means that this package is a popular or best-selling product. Conversely, if the actual first shipment volume of this package within a specified time period is less than the first shipment volume threshold, it means that this package is a leftover product.

[0275] When the warehouse storage system determines based on the first outgoing volume within a specified time period that the cargo stored in the first container is a popular or best-selling item, i.e., the actual first outgoing volume of this cargo within a specified time period is greater than the first outgoing volume threshold, the container loading / unloading device of the warehouse storage system grabs the first container from the rack in the rack stay area and transfers the first container to the multi-function area for temporary storage.

[0276] In S200, upon receiving a command to pick the cargo in the first container, the container unloading device transfers the first container from the multi-function area to a picking workspace in the workstation area for picking by a worker or picking robot.

[0277] Of course, in some other embodiments, the picker may not utilize a container unloading device and may directly transfer the first container from the multi-function area to the picking workspace in the workstation area.

[0278] In S300, after picking is completed, the container unloading device returns the first container that still has cargo remaining to the multi-function area for temporary storage, or directly returns the empty first container to the empty material box storage area.

[0279] In particular, the picking system can identify materials that are not currently needed but will be needed in a certain time. After the multi-function area is set up, the system can acquire more materials than are needed for the current sowing wall. That is, if the rack contains materials needed for the current sowing wall, as well as materials that will be used in a certain time, the container unloading device can remove the previously needed materials from the rack and temporarily store them in the multi-function area. When these materials are needed, the container unloading device can directly remove these materials or the containers containing these materials from the multi-function area and transport them to the picking position for picking, thereby accelerating the order completion speed and effectively reducing the number of rack transports by the automated transport device.

[0280] It should be noted that popular products may be stored directly in the multi-function area when they are received, or they may be removed from the warehouse storage area when they are picked and then stored directly in the multi-function area after the picking is complete. (Control Method Example 8)

[0281] Referring to FIG. 9, in this embodiment, the control method for the warehouse storage system includes the following steps S101, S201 and S301.

[0282] In S101, if the daily outgoing volume of the cargo in the second container on the next day is greater than the daily outgoing volume threshold, the container loading / unloading device transfers the second container from the rack in the rack stay area to the multi-function area for temporary storage.

[0283] It should be noted that the daily shipping volume threshold is a specific value or a range of values ​​that is preset for the amount of cargo shipped in a day. The daily shipping volume threshold depends on factors such as the type of cargo and the season. For example, the daily shipping volume of ice cream in summer is higher than the daily shipping volume in winter.

[0284] In detail, in one embodiment, when the warehouse storage system receives a reservation order for the next day, it compares the magnitude relationship between the daily output volume of the target cargo in the reservation order for the next day and the daily output volume threshold, and if the target cargo is stored in a second container and the daily output volume of the target cargo in the reservation order for the next day is greater than the daily output volume threshold, the warehouse storage system calls an automatic transport device to transport the rack storing the second container to the rack docking area, and the container loading and unloading device transfers the second container from the rack in the rack docking area to the multi-function area for temporary storage.

[0285] In another embodiment, when the warehouse storage system determines in advance that the actual outgoing volume of the target cargo stored in the second container on that day is greater than the daily outgoing volume threshold of the target cargo on the following day, it calls an automatic transport device to transport the rack storing the second container to the rack stay area, and the container loading and unloading device transfers the second container from the rack in the rack stay area to the multi-function area for temporary storage.

[0286] For example, for cargo such as fruits and vegetables whose shipping volume is seasonal, the warehouse storage system may discover that the daily shipping volume of heart-shaped apples on October 10th at the end of autumn far exceeded the preset daily shipping volume threshold for this cargo. Based on this, the warehouse storage system determines in advance that the daily shipping volume of heart-shaped apples the following day will also exceed the daily shipping volume threshold. The warehouse storage system calls the automatic transport device to transport the rack containing the second container to the rack docking area, and the container loading / unloading device transfers the second container from the rack in the rack docking area to the multi-function area for temporary storage, and stores the target cargo, the heart-shaped apples, in the second container.

[0287] In S201, when the warehouse storage system receives a command to pick the cargo in the second container the next day, the container unloading device transfers the second container from the multi-function area to a picking workspace in the workstation area for picking by a worker or a picking robot.

[0288] In S301, after picking is completed, the container unloading device returns the second container that still has cargo remaining to the multi-function area for temporary storage, or directly returns the empty second container to the empty material box storage area. (Control Method Example 9)

[0289] Referring to FIG. 10, in this embodiment, the control method for the warehouse storage system includes the following steps S102, S202, S203 and S302.

[0290] In S102, when an item related to the designated cargo is stored in the third container on the rack, the container loading / unloading device transfers the third container from the rack in the rack stay area to the multi-function area for temporary storage.

[0291] Here, the item related to the designated item may be a free gift for the designated item, which is an item given free of charge when purchasing the designated item. Of course, the item related to the designated item may also be a product that is discounted when ordered in the same order as the designated item.

[0292] Before step S102, this control method further includes the step of calling an automatic transport device to transport the rack storing the third container to the rack stay area.

[0293] At S202, when the warehouse storage system receives a command to pick the designated shipment, the container unloading device transfers the third container from the multi-function area to the picking workspace for picking by a worker or picking robot.

[0294] Before or after step S202, the control method further includes step S203 in which the warehouse storage system calls an automatic transport device to transport the rack storing the designated cargo to the rack stay area, and the container loading and unloading device transfers the fifth container storing the designated cargo on the rack from the rack in the rack stay area to the picking work space in the workstation area.

[0295] In S302, after picking is completed, the container unloading device returns the third container in which the items related to the designated cargo still remain to the multi-function area for temporary storage, or directly returns the empty third container to the empty material box storage area, and returns the fourth container in which the designated cargo still remains to the rack, or directly returns the empty fourth container to the empty material box storage area.

[0296] It should be noted that items related to designated cargo may be stored directly in the multi-function area when they are received, or when a popular product is to be picked, they may be removed from the warehouse storage area and stored directly in the multi-function area after picking is complete. (Control Method Example 10)

[0297] In this embodiment, the control method for the warehouse storage system includes: When the container unloading device is idle, the step of adjusting the positions of the different containers on the rack by the multi-function area is included.

[0298] When the container loading / unloading device is idle, the warehouse storage system calls an automatic transport device to transport the rack to the rack stay area, and based on the types of goods stored in the rack and the output volume of various goods in previous orders, the warehouse storage system adjusts the positions of different containers on the rack, for example, moving the fifth container, which stores goods with a high output volume, outside the sixth container, which stores goods with a low output volume, thereby shortening the picking time and improving picking efficiency.

[0299] In detail, the warehouse storage system determines whether the quantity of goods to be shipped on the rack is high or low based on previous orders. If the fifth container of the goods with a high quantity of goods to be shipped is located inside the sixth container of the goods with a low quantity of goods to be shipped, the container loading / unloading device will first transfer the sixth container of the goods with a low quantity of goods to the rack to the multi-functional area for temporary storage, then transfer the fifth container of the goods with a high quantity of goods to the multi-functional area for temporary storage, and then return the sixth container of the goods with a low quantity of goods to the rack from the multi-functional area, and finally return the fifth container of the goods with a high quantity of goods to the rack from the multi-functional area and position it outside the sixth container of the goods with a low quantity of goods to be shipped, thereby making it easier to grab.

[0300] Alternatively, the container loading / unloading device adjusts the fifth container of the cargo with a high outgoing volume on the rack to a low position on the rack, and adjusts the sixth container of the cargo with a low outgoing volume on the rack to a high position on the rack.

[0301] In detail, the warehouse storage system calls an automatic transport device to transport a rack to the rack docking area, and determines in advance the output volume classes of various cargoes on this rack based on previous orders. Based on this, the container loading and unloading device first transfers the sixth container of cargoes with low output volumes in the low-level position of the rack to the multi-function area for temporary storage, then moves the fifth container of cargoes with high output volumes located in the high-level position of the rack to the above-mentioned low-level position, and then returns the sixth container temporarily stored in the multi-function area to the high-level position of the rack, and repeats this operation until all the cargoes with high output volumes on the rack are located below the cargoes with low output volumes, thereby facilitating loading and unloading. (Control Method Example 11)

[0302] In this embodiment, the control method for a warehouse storage system includes the following steps.

[0303] Empty containers are stored in the multi-function area.

[0304] It is to be noted that empty containers may be stored in a rack in advance, the warehouse storage system may call an automated transport device to transport the rack to the rack docking area, and then a container loading / unloading device may transfer the empty container from the rack to a multi-function area for temporary storage.

[0305] When the warehouse storage system receives a command to load a full box or an external container supply shortage alert, the container unloading device transfers an empty container from the multi-function area to the picking workspace, so that a worker or picking robot can pick the load into the empty container.

[0306] It should be noted that loading a whole box means that the container must be fully packed and then sold as a whole.

[0307] Finally, the following should be stated: The above examples are merely specific embodiments of the present disclosure, and are intended to illustrate the technical means of the present disclosure but not to limit it, and the scope of protection of the present disclosure is not limited thereto.
