Description

Technical Field

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

[0002] The warehouse system's shelving is equipped with multiple storage locations for goods. Elevators capable of lifting and lowering items are installed around the shelving. This allows transport vehicles to use the elevators to move goods between the storage locations and the external transport lines, facilitating the inbound and outbound processes.

[0003] However, in related technologies, when transferring goods, the transfer vehicle needs to move back and forth between the storage location and the hoist, as well as between the hoist and the transport line. Furthermore, when multiple transfer vehicles work simultaneously, their movement paths conflict, reducing the efficiency of goods transfer. Utility Model Content

[0071] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0072] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0073] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In this application, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0074] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities at the point of connection are not connected through a transitional structure, but are simply linked together to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0075] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0076] Warehousing systems enable efficient storage of goods and meet rapid sorting needs, ensuring the smooth operation of the supply chain. Warehousing systems can include vehicles, transfer carts, and elevators.

[0077] In some examples, the carrier can be a rack with multiple storage levels, each level of which can include multiple storage locations. For example, the rack can be a four-way truck rack, densely arranged in a storage area.

[0078] In some examples, the vehicle is used to carry items. Items include, but are not limited to, cargo, original boxes or packages containing cargo, containers containing cargo or original boxes, etc., wherein containers may include, but are not limited to, bins, pallets, etc.

[0079] In some examples, the transfer vehicle can be a four-way transfer vehicle, which can operate within the storage area, such as moving items within shelves.

[0080] In some examples, the storage area can accommodate multiple shelves simultaneously. Aisles can be provided between the shelves, adjacent to each other. Transfer vehicles can travel through these aisles. For example, a transfer vehicle can travel through an aisle between a first and a second shelf, moving from the first shelf to the second, or vice versa, to transfer items between different shelves.

[0081] In some examples, the transfer vehicle can travel along the cargo channels set up in each reservoir. For instance, the transfer vehicle can travel along cargo channels in different directions within the reservoir, and it can also turn at the junctions of cargo channels in different directions.

[0082] In some examples, the hoist can move the transfer cart up and down along the height of the rack to allow the cart to be moved between different storage levels and the ground.

[0083] In some examples, after a transfer cart retrieves an item from a designated location on the shelf, it can travel along the aisle to a lift. The lift can carry the transfer cart with the items and move it up and down between different storage levels to transfer items between them.

[0084] In related technologies, warehousing and outbound operations require the transfer of goods between the inside and outside of the storage area. However, transfer vehicles operating inside the storage area cannot directly transfer goods from inside to outside. Therefore, transportation equipment, such as transport lines and conveyor belts, needs to be installed in the area where the hoist is located to enable the transfer of goods between the storage area and outside.

[0085] In some examples, the warehousing system also includes transport lines located outside the warehousing area to move goods between the warehousing area and the outside.

[0086] In some examples, when items are received, the picking party needs to place the items to be received, which are located outside the storage area, on a conveyor line. The conveyor line then transports the items to an elevator, which lifts the items to a designated storage layer on the shelf. Next, a transfer vehicle located on the storage layer transports the items out of the elevator and moves them to the storage location, where they are then placed to complete the receiving process.

[0087] In some examples, when goods are to be shipped out, a transfer vehicle located on the storage floor enters the storage location and retrieves the goods to be shipped out. The transfer vehicle can then transport the goods to the elevator, which can then transport the goods to the transport line. Finally, the transport line can transport the goods outside the storage area, completing the outbound shipment.

[0088] In some examples, buffer spaces can be set up between the inside and outside of the storage area. These buffer spaces can be located at the bottom of the shelves and are used to temporarily place items to alleviate the logistical pressure of transferring goods.

[0089] In some examples, during the inbound process, the picking party can place the item to be inbound in a buffer location. Then, a transfer vehicle located within the storage area can enter the buffer location to retrieve the item and transfer it from the buffer location to an elevator. Once the elevator carries the item to the designated storage level on the shelf, the transfer vehicle then transfers the item from the elevator to the storage location.

[0090] In some examples, during the outbound process, a transfer vehicle can enter a storage location, retrieve the items to be shipped, and then transfer the items from the storage location to a lift. Once the items on the lift have descended to the bottom of the shelf, the transfer vehicle then transfers the items from the lift to a buffer location.

[0091] In the aforementioned warehousing system, transfer vehicles can dock with elevators to move goods between the inside and outside of the storage area via the elevators and the conveyor lines arranged around them. However, when transferring goods, the transfer vehicles need to move back and forth between the storage location and the elevator, or between the elevator and the conveyor lines. Furthermore, when multiple transfer vehicles are working simultaneously, their movement paths may conflict, reducing the efficiency of goods transfer.

[0092] To address the problem of conflicting movement paths of transfer vehicles during the transportation of goods, resulting in low efficiency in goods transfer, some embodiments of this application provide a warehousing system.

[0093] Figure 1 This is a top view of a warehousing system provided in some embodiments of this application. Figure 2 A partial enlarged view of a warehousing system provided for some embodiments of this application.

[0094] See Figure 1 and Figure 2 The warehousing system includes: a vehicle 100, which is used to place items.

[0095] In some examples, the vehicle 100 has multiple storage layers 110 along its height. Each storage layer 110 may be configured with multiple storage locations 120 for placing items P. Each storage location 120 may hold one item P, or multiple items P of the same category or different categories may be placed depending on the space of the storage location 120 and the volume of the item P.

[0096] In some examples, multiple storage locations 120 may be arranged along at least one of the length, width and height directions of the vehicle 100, or in other ways, such as in a ring.

[0097] In some examples, multiple storage locations 120 can be arranged in layers within a single storage layer 110. For example, each storage layer 110 of the vehicle 100 may include multiple stacked storage locations, and multiple storage locations 120 can be arranged in each storage location layer to efficiently utilize the space between storage layers 110 and increase the storage capacity of the vehicle 100.

[0098] In some examples, each storage layer 110 may have a cargo aisle. The cargo aisle may be adjacent to the storage location 120, for example, the cargo aisle may be located between two rows of storage locations 120, that is, the storage locations 120 are located on both sides of the cargo aisle.

[0099] In some examples, the storage positions 120 may be arranged along the length or width of the reservoir 110, or in at least one horizontal direction of the plane in which the reservoir 110 is located.

[0100] In some examples, the arrangement direction of the storage positions 120 between different storage layers 110 can be the same. For example, the storage positions 120 in each storage layer 110 of the carrier 100 are arranged along the length direction of the storage layer 110. The arrangement direction of the storage positions 120 between different storage layers 110 can also be different. For example, the storage positions 120 in the first storage layer 110 of the carrier 100 are arranged along the length direction of the storage layer 110, while the storage positions 120 in the second storage layer 110 of the carrier 100 are arranged along the width direction of the storage layer 110. This application embodiment does not limit the arrangement direction of the storage positions.

[0101] In some examples, the aisles can be arranged in one or more directions, and aisles in different directions can be connected. For example, an aisle extending along the length direction can be connected to multiple aisles arranged along the width direction, and an aisle extending along the width direction can be connected to multiple aisles arranged along the length direction. At least one side of each storage location is connected to an aisle so that an item P taken from any storage location can be moved out from one of the aisles.

[0102] In some examples, the storage system may include multiple vehicles 100, and aisles may be provided between different vehicles 100. Depending on the arrangement direction and placement of the multiple vehicles 100, the aisles may be arranged in one or more directions. For example, aisles extending perpendicular to the arrangement direction may be arranged between adjacent vehicles 100 placed along the arrangement direction of the vehicles 100.

[0103] In some examples, the storage system may include a first lifting mechanism 200 and a second lifting mechanism 300, which may be located within an aisle and docked at different positions on the vehicle 100. The first lifting mechanism 200 and the second lifting mechanism 300 can lift and lower items P.

[0104] In some examples, the first lifting mechanism 200 may include a first lifting platform 210, which may be connected to the first channel 500 and may carry an item P, so as to realize the lifting of the first lifting platform 210 carrying the item P.

[0105] In some examples, the second lifting mechanism 300 may include a second lifting platform 310, which may be docked with the first channel 500 and may carry an item P, so as to realize the lifting of the second lifting platform 310 carrying the item P.

[0106] In some examples, the first lifting platform 210 and the second lifting platform 310 can dock with either storage layer 110 of the vehicle 100 via lifting to transfer items P between different storage layers 110.

[0107] In some examples, the first lifting platform 210 and the second lifting platform 310 can simultaneously lift item P and simultaneously lower item P.

[0108] In some examples, the first lifting platform 210 and the second lifting platform 310 can respectively carry the item P to rise and fall. For example, the first lifting platform 210 carries the item P to rise, while the second lifting platform 310 carries the item P to fall.

[0109] In some examples, the storage system may include a drive mechanism that can be connected to the first lifting platform 210 and the second lifting platform 310, respectively. The drive mechanism can move the first lifting platform 210 and / or the second lifting platform 310 up and down along the height direction of the carrier 100.

[0110] In some examples, the drive mechanism includes a drive motor and a lifting belt meshing with the drive motor. A first lifting platform 210 and a second lifting platform 310 can be connected to different positions on the lifting belt, respectively. The drive motor can adjust the steering to raise or lower the first lifting platform 210 and / or the second lifting platform 310.

[0111] In some examples, the drive motor rotates forward, which can cause the lifting belt to slide in a clockwise direction, thereby lifting the first lifting platform 210 and / or the second lifting platform 310.

[0112] In some examples, the drive motor reverses, which can cause the lifting belt to slide counterclockwise, thereby causing the first lifting platform 210 and / or the second lifting platform 310 to descend.

[0113] In some examples, there can be multiple drive mechanisms. Each drive mechanism can individually control the first lifting platform 210 to move up and down in the height direction, or each drive mechanism can individually control the second lifting platform 310 to move up and down in the height direction. Multiple drive mechanisms can also operate simultaneously to control both the first lifting platform 210 and the second lifting platform 310 to move up and down in the height direction at the same time.

[0114] In some examples, the warehousing system also includes a cache bit 400.

[0115] Buffer location 400 can temporarily hold item P. During the inbound and outbound processes of item P, item P can circulate within the area where buffer location 400 is located. For example, buffer location 400 can hold item P1, which is being transferred from outside the storage area to buffer location 400 for inbound processing, or buffer location 400 can hold item P2, which is being transferred from storage location 120 for outbound processing.

[0116] In some examples, cache bit 400 can be set inside or outside vehicle 100.

[0117] In some examples, where the cache bit 400 is located inside the vehicle 100, the cache bit 400 may be located at the bottom of the vehicle 100. Exemplarily, the bottom of the vehicle 100 may be the region corresponding to the lowest storage layer 110 (i.e., the first storage layer 110) of the vehicle 100. Exemplarily, the bottom of the vehicle 100 may be the region corresponding to multiple storage layers 110 starting from the lowest storage layer 110 of the vehicle 100; for example, the bottom of the vehicle 100 may be the region corresponding to the first, second, and third storage layers 110 of the vehicle 100.

[0118] In some examples, the bottom of the vehicle 100 may be equipped with both a storage location 120 and a buffer location 400, so that the item P to be stored can be placed in the storage location 120, or the item P1 to be stored or the item P2 to be shipped can be temporarily placed in the buffer location 400.

[0119] In some examples, the bottom of vehicle 100 can be entirely set as cache slots 400 to increase the number of items P1 to be temporarily placed or items P2 to be temporarily removed.

[0120] In some examples, cache bit 400 can also be set in other storage layers 110 outside the bottom of vehicle 100.

[0121] In some examples, where the buffer position 400 is located outside the vehicle 100, the buffer position 400 may be located on at least one side of the vehicle 100, for example, the buffer position 400 may be located on at least one side of the bottom of the vehicle 100. Exemplarily, the buffer position 400 may be located on at least one side of the bottom of the vehicle 100 near the outside of the storage area to facilitate the transfer of item P between the inside and outside of the storage area.

[0122] In some examples, when the buffer 400 is located outside the vehicle 100, the bottom of the vehicle 100 can be a location on the outside of the vehicle 100 close to the ground. Exemplarily, the bottom of the vehicle 100 can be an area on the outside of the vehicle 100 corresponding to the height of the lowest reservoir 110 (i.e., the first reservoir 110). Exemplarily, the bottom of the vehicle 100 can be an area on the outside of the vehicle 100 corresponding to the height of multiple reservoirs 110 starting from the lowest reservoir 110.

[0123] In some examples, the buffer position 400 may be at a certain height from the ground to allow other transport equipment to enter the buffer position 400 from the bottom and transfer items P between the buffer position 400 and the outside of the storage area.

[0124] In some examples, buffer 400 can be adjacent to vehicle 100 or separated from vehicle 100 by a certain distance.

[0125] In some examples, the storage system may include multiple cache positions 400, which may be arranged according to the shape of the vehicle 100. For example, when the vehicle 100 is a cuboid structure, the cache positions 400 may be arranged in a rectangle and arranged around the outside of the vehicle 100.

[0126] In some examples, the warehousing system also includes a first channel 500.

[0127] In some examples, the first channel 500 can sequentially connect with the first lifting mechanism 200, the buffer position 400, and the second lifting mechanism 300 along its extension direction. This forms a loop transport path between the first lifting mechanism 200 and the buffer position 400, or between the buffer position 400 and the second lifting mechanism 300, improving the transfer efficiency of item P between the first lifting mechanism 200, the buffer position 400, and the second lifting mechanism 300.

[0128] In some examples, the first lifting mechanism 200 can lift the first lifting platform 210 so that the first lifting platform 210 docks with the first channel 500.

[0129] In some examples, the second lifting mechanism 300 can lift the second lifting platform 310 so that the second lifting platform 310 docks with the first channel 500.

[0130] In some examples, the first channel 500 can be arranged according to the position of the buffer position 400. For example, if the buffer position 400 is located inside the vehicle 100, the first channel 500 can be located inside the vehicle 100 and dock with the buffer position 400. If the buffer position 400 is located outside the vehicle 100, the first channel 500 can extend from inside the vehicle 100 to outside the vehicle 100 and dock with the buffer position 400.

[0131] In some examples, Figure 2 The structure inside the dashed box is located at the bottom of vehicle 100. For example... Figure 2 As shown, when the buffer position 400 is located at the bottom of the vehicle 100, the first channel 500 can also be located at the bottom of the vehicle 100 so that the first channel 500 can be connected to the buffer position 400.

[0132] In some examples, the warehousing system also includes a transfer vehicle 600.

[0133] The transfer vehicle 600 can be a four-way transfer vehicle. The four-way transfer vehicle can travel within each reservoir 110, or at the bottom of the vehicle 100. The transfer vehicle 600 can travel in four directions: forward, backward, left, and right.

[0134] In some examples, the transfer vehicle 600 can also perform operations such as turning and U-turns.

[0135] In some examples, the width of the first channel 500 can be adapted to the width of the transfer vehicle 600. The first channel 500 can be provided with transport tracks 510 on both sides in the width direction, and the transfer vehicle 600 can travel along the transport tracks 510 within the first channel 500.

[0136] In some examples, the transport track 510 may include a raised structure, and the hub of the transfer vehicle 600 or a groove provided on the bottom of the transfer vehicle 600 may slide in conjunction with the raised structure to allow the transfer vehicle 600 to travel along the first channel 500 via the transport track 510.

[0137] In some examples, the transfer vehicle 600 can travel on the first channel 500 to transfer the item P2 to be shipped out from the first lifting platform 210 to the buffer position 400, or to transfer the item P1 to be shipped in from the buffer position 400 to the second lifting platform 310.

[0138] In some examples, the first lifting platform 210 and the second lifting platform 310 can lift and lower the item P, or lift and lower the transfer vehicle 600 carrying the item P or the empty transfer vehicle 600.

[0139] See also Figure 2 When the first lifting platform 210 and the second lifting platform 310 are lifting the item P, the transfer vehicle 600 can transfer the item P2 to be shipped out through the following process based on the warehousing system provided in some embodiments of this application.

[0140] In some examples, when the first lifting platform 210 is connected to the first channel 500, the transfer vehicle 600 can travel from the first channel 500 to the first lifting platform 210 to retrieve the item P2 to be shipped out, which is carried on the first lifting platform 210. Then, the transfer vehicle 600 can carry the item P2 from the first lifting platform 210 through the first channel 500 to the buffer position 400, placing the item P2 in the buffer position 400 to transfer it from the first lifting platform 210 to the buffer position 400. Next, after transferring the item P2 from the first lifting platform 210 to the buffer position 400, the transfer vehicle 600 can travel from the buffer position 400 to the first channel 500 and continue along the first channel 500 to enter another buffer position 400 containing the item P1 to be received, retrieving the item P1. Next, with the second lifting platform 310 connected to the first channel 500, the transfer vehicle 600 can carry the item P1 to be stored from the buffer position 400 through the first channel 500 to the second lifting platform 310, place the item P1 to be stored in the second lifting platform 310, and then move from the second lifting platform 310 to the first channel 500 to transfer the item P1 to be stored from the buffer position 400 to the second lifting platform 310.

[0141] The technical solution provided in this application embodiment uses a first lifting mechanism 200 and a second lifting mechanism 300, which are connected to different positions on the carrier 100, to lift and lower items P on both sides of the carrier 100. A first channel 500 sequentially connects to the first lifting mechanism 200, a buffer position 400, and the second lifting mechanism 300 along its extension direction, thereby forming a circular transport route on one side of the carrier 100. The transfer vehicle 600 can travel in the same direction along the circular transport route.

[0142] The technical solution provided in this application embodiment allows the transfer vehicle 600 to transfer items P2 to be shipped out from the first lifting mechanism 200 on one side of the carrier 100 to the buffer position 400, and then transfer items P1 to be received from the buffer position 400 to the second lifting mechanism 300 on the other side of the carrier 100, thereby realizing circular transportation of items P. Furthermore, this reduces the back-and-forth movement of the transfer vehicle 600, avoids conflicts in the movement paths of multiple transfer vehicles 600, and improves the efficiency of the transfer vehicle 600 in transferring items P.

[0143] Figure 3 This is a top view of a transfer vehicle moving items between a buffer position and a lifting mechanism in some embodiments of this application.

[0144] See Figure 3 When the first lifting platform 210 and the second lifting platform 310 lift the transfer vehicle 600 carrying the item P, the transfer vehicle 600 can transfer the item P2 to be shipped out through the following process based on the warehousing system provided in some embodiments of this application.

[0145] In some examples, Figure 3 The structure inside the dashed box is located at the bottom of vehicle 100.

[0146] In some examples, when the first lifting platform 210 is connected to the first channel 500, the transfer vehicle 600 can carry the item P2 to be shipped out from the first lifting platform 210 to the first channel 500, enter the buffer position 400, and place the item P2 in the buffer position 400 to transfer the item P2 from the first lifting platform 210 to the buffer position 400. Next, after transferring the item P2 from the first lifting platform 210 to the buffer position 400, the transfer vehicle 600 can travel from the buffer position 400 to the first channel 500 and continue along the first channel 500 to enter another buffer position 400 containing the item P1 to be received, and retrieve the item P1. Next, with the second lifting platform 310 connected to the first channel 500, the transfer vehicle 600 can carry the item P1 to be stored from the buffer position 400 through the first channel 500 to the second lifting platform 310, so as to transfer the item P1 to be stored from the buffer position 400 to the second lifting platform 310.

[0147] The technical solution provided in this application embodiment allows the transfer vehicle 600 to carry the item P2 to be shipped out from the first lifting mechanism 200 on one side of the carrier 100 to the buffer position 400, and then carry the item to be shipped in from the P1 buffer position 400 to the second lifting mechanism 300 on the other side of the carrier 100 to transfer the item P1 to be shipped in, thereby reducing the number of times the transfer vehicle 600 docks with each lifting mechanism and improving the efficiency of the transfer vehicle 600 in transferring the item P.

[0148] In some examples, multiple transfer vehicles 600 can travel simultaneously within the first channel 500, with a certain distance between them to reduce the risk of collisions. This also increases the number of items P that can be transferred in parallel within the warehousing system, thereby improving the transfer efficiency of items P.

[0149] It should be noted that in another example provided in this application, the transfer vehicle 600 can also transfer the item P2 to be shipped out from the second lifting platform 310 to the buffer position 400, or transfer the item P1 to be received from the buffer position 400 to the first lifting platform 210, so as to transfer the item P in the opposite direction between the second lifting platform 310, the buffer position 400 and the first lifting platform 210. The implementation method of the transfer vehicle 600 transferring the item P between the second lifting platform 310, the buffer position 400 and the first lifting platform 210 can be referred to the foregoing embodiments, and will not be repeated here.

[0150] Figure 4 This is a top view of a transfer vehicle moving items between a cargo space and a lifting mechanism in some embodiments of this application.

[0151] See Figure 4 In some examples, reservoir 110 is also provided with a second channel 130.

[0152] In some examples, the second channel 130 may dock with the first lifting mechanism 200 and the second lifting mechanism 300 to provide a travel path for the transfer vehicle 600 between the first lifting mechanism 200, the storage location 120 and the second lifting mechanism 300, thereby forming a loop transport path between the first lifting mechanism 200 and the buffer location 400, or between the buffer location 400 and the second lifting mechanism 300, improving the transfer efficiency of the item P between the first lifting mechanism 200, the storage location 120 and the second lifting mechanism 300.

[0153] In some examples, the first lifting mechanism 200 can lift the first lifting platform 210 so that the first lifting platform 210 docks with the second channel 130.

[0154] In some examples, the second lifting mechanism 300 can lift the second lifting platform 310 so that the second lifting platform 310 docks with the second channel 130.

[0155] In some examples, when the second lifting platform 310 is connected to the second channel 130, the transfer vehicle 600 can travel from the second channel 130 to the second lifting platform 310 to retrieve the item P1 to be received, which is carried on the second lifting platform 310. Then, the transfer vehicle 600 can carry the item P1 from the second lifting platform 310 through the second channel 130 to the storage location 120, place the item P1 in the storage location 120, and then travel from the storage location 120 to the second channel 130 to transfer the item P1 from the second lifting platform 310 to the storage location 120. Next, the transfer vehicle 600 can retrieve the item P2 to be shipped out from another storage location 120. Next, with the first lifting platform 210 connected to the second channel 130, the transfer vehicle 600 can carry the item P2 to be shipped from the storage location 120 through the second channel 130 to the first lifting platform 210, place the item P on the first lifting platform 210, and then move from the first lifting platform 210 to the second channel 130 to transfer the item P2 from the storage location 120 to the first lifting platform 210. The transfer vehicle 600 can then move from the first lifting platform 210 through the second channel 130 to the second lifting platform 310, repeating the above process.

[0156] In some examples, the width of the second channel 130 can be adapted to the width of the transfer vehicle 600. Guide rails 140 can be provided on both sides of the second channel 130 in the width direction. The transfer vehicle 600 can travel within the second channel 130 via the guide rails 140.

[0157] In some examples, the guide rail 140 may include a raised structure, and the hub of the transfer vehicle 600 or a groove provided at the bottom of the transfer vehicle 600 may slide in conjunction with the raised structure of the guide rail 140, so that the transfer vehicle 600 may travel along the second channel 130 via the guide rail 140.

[0158] The technical solution provided in this application embodiment involves the second channel 130 of the storage layer 110 of the carrier 100 docking with the first lifting mechanism 200 and the second lifting mechanism 300. When the transfer vehicle 600 performs inbound and outbound tasks in the storage layer 110 of the carrier 100, it can transfer the item P1 to be stored from the second lifting mechanism 300 located on one side of the carrier 100 to the storage location 120, and then transfer the item P2 to be unstored from the storage location 120 to the first lifting mechanism 200 located on the other side of the carrier 100, thereby forming a circular transportation route inside the carrier 100 and improving the efficiency of the transfer vehicle 600 in transferring the item P between the first lifting mechanism 200, the storage location 120, and the second lifting mechanism 300.

[0159] Figure 5 This is a top view of the transfer vehicle entering and exiting the first lifting mechanism in some embodiments of this application.

[0160] See Figure 5 In some examples, the second channel 130 may be connected to at least two sides of the first lifting mechanism 200 when the first lifting mechanism 200 lifts the first lifting platform 210 to the reservoir 110, the second channel 130 of the reservoir 110 is connected to at least two sides of the first lifting platform 210.

[0161] In some examples, taking the second channel 130 connected to both sides of the first lifting platform 210 as an example, the second channel 130 can be connected to both sides of the first lifting platform 210 in the same horizontal direction, for example, the front and back sides in the horizontal direction, or the left and right sides in the horizontal direction.

[0162] When the first lifting platform 210 carries the item P and lifts, based on the warehousing system provided in some embodiments of this application, the transfer vehicle 600 can transfer the item P2 to be shipped out from the storage location 120 to the first lifting platform 210 within the storage layer 110 through the following process.

[0163] In some examples, when the first lifting platform 210 is connected to the second channel 130, the transfer vehicle 600 can carry the item P2 to be shipped from the second channel 130 on one side of the first lifting platform 210 into the first lifting platform 210, and place the item P2 on the first lifting platform 210. Then, the empty transfer vehicle 600 continues to travel in the current direction to the second channel 130 on the other side of the first lifting platform 210 to leave the first lifting platform 210.

[0164] In some examples, the second channel 130 can also connect to three sides of the first lifting platform 210. For example, the second channel 130 can connect to the front and rear sides of the first lifting platform 210 in the horizontal direction, and also to the right side in the horizontal direction. In this way, when the transfer vehicle 600 travels in the front and rear directions of the first lifting platform 210, it can carry the item P2 to be shipped out from the second channel 130 on the front side of the first lifting platform 210 into the first lifting platform 210 while the first lifting platform 210 is connected to the second channel 130, so as to place the item P2 to be shipped out in the first lifting platform 210, and then continue to travel to the second channel 130 on the rear side of the first lifting platform 210 to leave the first lifting platform 210.

[0165] In some examples, when the first lifting platform 210 is docked with the second channel 130, the transfer vehicle 600 can also carry the item P2 to be retrieved into the first lifting platform 210 through the second channel 130 on either the front or rear side of the first lifting platform 210, so as to place the item P2 in the first lifting platform 210. Then, the transfer vehicle 600 can leave the first lifting platform 210 through the second channel 130 on the right side of the first lifting platform 210 by turning within the first lifting platform 210.

[0166] In some examples, the transfer vehicle 600 may also carry the item P2 to be shipped into the first lifting platform 210 via the second passage 130 on the right side of the first lifting platform 210, so as to place the item P2 in the first lifting platform 210. Then, the transfer vehicle 600 may leave the first lifting platform 210 within the first lifting platform 210 by turning and exiting via the second passage 130 on either the front or rear side of the first lifting platform 210.

[0167] In some examples, the second channel 130 can also be connected to the four sides of the first lifting platform 210. For example, the second channel 130 can be connected to the front and rear sides of the first lifting platform 210 in the horizontal direction, as well as the left and right sides in the horizontal direction.

[0168] In this way, the transfer vehicle 600 can enter the first lifting platform 210 through the second passage 130 on any one of the four sides, and then exit the first lifting platform 210 through the second passage 130 on any of the remaining three sides, so as to transfer the item P2 to be shipped from the storage location 120 to the second lifting mechanism 300. The implementation method of the transfer vehicle 600 entering and exiting between the second passage 130 and the first lifting platform 210 can be referred to the above example, and will not be repeated here.

[0169] The technical solution provided in this application embodiment allows the second channel 130 to connect to the first lifting mechanism 200 from multiple directions. The transfer vehicle 600 can enter the first lifting mechanism 200 from one side of the second channel 130, place the item P2 to be retrieved on the first lifting platform 210, and then leave the first lifting mechanism 200 from the other side of the second channel 130, achieving bidirectional entry and exit. This avoids obstructing subsequent entry of the transfer vehicle 600 into the first lifting mechanism 200, thereby improving the efficiency of the transfer vehicle 600 in transferring the item P2 to be retrieved.

[0170] Figure 6 This is a top view of the transfer vehicle entering and exiting the second lifting mechanism in some embodiments of this application.

[0171] See Figure 6In some examples, the second channel 130 may be connected to at least two sides of the second lifting mechanism 300. When the second lifting mechanism 300 lifts the second lifting platform 310 to the reservoir 110, the second channel 130 of the reservoir 110 is connected to at least two sides of the second lifting platform 310.

[0172] In some examples, taking the second channel 130 as an example of being connected to both sides of the second lifting platform 310, the second channel 130 can be connected to both sides of the second lifting platform 310 in the same horizontal direction, for example, the front and back sides in the horizontal direction, or the left and right sides in the horizontal direction.

[0173] When the second lifting platform 310 carries the item P, based on the warehousing system provided in some embodiments of this application, the transfer vehicle 600 can transfer the item P1 to be stored from the second lifting platform 310 to the storage location 120 within the storage layer 110 through the following process.

[0174] In some examples, when the second lifting platform 310 is connected to the second channel 130, the transfer vehicle 600 moves from the second channel 130 on one side of the second lifting platform 310 to enter the second lifting platform 310 to retrieve the item P1 to be stored on the second lifting platform 310. Then, the transfer vehicle 600 can carry the item P1 to the second channel 130 on the other side of the second lifting platform 310 to leave the second lifting platform 310 with the item P1 in it.

[0175] In some examples, the second channel 130 can also connect to three sides of the second lifting platform 310. For example, the second channel 130 can connect to the front and rear sides of the second lifting platform 310 in the horizontal direction, and also connect to the left side in the horizontal direction. In this way, when the transfer vehicle 600 travels along the front and rear sides of the second lifting platform 310, it can enter the second lifting platform 310 from the second channel 130 on the front side of the second lifting platform 310 while the second lifting platform 310 is connected to the second channel 130, to retrieve the item P1 to be stored on the second lifting platform 310, and then continue to the second channel 130 on the rear side of the second lifting platform 310 to leave the second lifting platform 310.

[0176] In some examples, when the second lifting platform 310 is docked with the second channel 130, the transfer vehicle 600 can also enter the second lifting platform 310 from the second channel 130 on the front or rear side to retrieve the item P1 to be stored on the second lifting platform 310. Then, the transfer vehicle 600 can exit the second lifting platform 310 from the second channel 130 on the left side by turning within the second lifting platform 310.

[0177] In some examples, the transfer vehicle 600 can also enter the second lifting platform 310 from the second passage 130 on the right side of the second lifting platform 310 to retrieve the item P1 to be stored on the second lifting platform 310. Then, the transfer vehicle 600 can carry the item P1 to be stored and exit the second lifting platform 310 from the second passage 130 on the front or rear side of the second lifting platform 310 by turning within the second lifting platform 310.

[0178] In some examples, the second channel 130 can also be connected to the four sides of the second lifting platform 310. For example, the second channel 130 can be connected to the front and rear sides of the second lifting platform 310 in the horizontal direction, as well as the left and right sides in the horizontal direction.

[0179] In this way, the transfer vehicle 600 can enter the second lifting platform 310 through the second passage 130 on any one of the four sides to retrieve the item P1 to be stored on the second lifting platform 310, and then exit the second lifting platform 310 through the second passage 130 on any of the remaining three sides to transfer the item P2 to be stored from the second lifting mechanism 300 to the storage location 120. The method by which the transfer vehicle 600 enters and exits between the second passage 130 and the second lifting platform 310 can be referred to the above example, and will not be repeated here.

[0180] The technical solution provided in this application embodiment allows the second channel 130 to connect to the second lifting mechanism 300 from multiple directions. The transfer vehicle 600 can enter the second lifting mechanism 300 from one side of the second channel 130 to retrieve the item P1 to be stored on the second lifting platform 310, and then exit from the second lifting mechanism 300 from the other side of the second channel 130, achieving bidirectional entry and exit. This avoids obstructing subsequent entry of the transfer vehicle 600 into the second lifting mechanism 300, thereby improving the efficiency of the transfer vehicle 600 in transferring the item P1 to be stored.

[0181] In some examples, after the transfer vehicle 600, carrying the item P1 to be received, leaves the second lifting platform 310 through the second channel 130, it can travel through the second channel 130 to the entry storage location 120 to place the item P1 in the storage location 120. At this time, the transfer vehicle 600 changes from a loaded state to an empty state. The empty transfer vehicle 600 can travel from the current storage location 120 through the cargo channel to the storage location 120 where the item P2 to be retrieved is placed, and then the transfer vehicle 600 can travel through the second channel 130 to the second lifting platform 310 to continue performing the outbound task. The implementation method of the transfer vehicle 600 performing the outbound task can be referred to the aforementioned examples, and will not be repeated here.

[0182] Figure 7This is a top view of a first embodiment of a transfer vehicle for circular transport of articles, as described in some embodiments of this application.

[0183] In some examples, Figure 7 The structure inside the dashed box is located at the bottom of vehicle 100.

[0184] See Figure 7 In some examples, cache bit 400 may include a first cache bit 410 and a second cache bit 420, wherein the first cache bit 410 is used to temporarily place the item P2 to be shipped out, and the second cache bit 420 is used to temporarily place the item P1 to be received, so as to classify and place different types of items P.

[0185] In some examples, the first buffer bit 410 and the second buffer bit 420 can be set at different positions on either side of the vehicle 100, or on any different side of the vehicle 100.

[0186] In some examples, the first channel 500 is sequentially connected to the first lifting mechanism 200, the first buffer position 410, the second buffer position 420, and the second lifting mechanism 300 along the extension direction to form a loop transportation path.

[0187] The technical solution provided in this application embodiment categorizes and places items P2 to be shipped out and items P1 to be received into the warehouse by setting different buffer positions 400. During the circular transportation of items P by the transfer vehicle 600, the transfer vehicle 600 can place items P2 to be shipped out in the first buffer position 410 and retrieve items P1 to be received into the warehouse from the second buffer position 420, so as to facilitate the setting of routes for items P to be received and shipped out, and improve the flexibility of setting the circular transportation route.

[0188] In some examples, when the first lifting platform 210 is docked with the first channel 500, the transfer vehicle 600 can move within the first channel 500 between the first lifting platform 210 and the first buffer position 410 to transfer the item P2 to be shipped out between the first lifting platform 210 and the first buffer position 410. Next, the transfer vehicle 600 can move from the first buffer position 410 through the first channel 500 to the second buffer position 420 to retrieve the item P1 to be received in the second buffer position 420. Then, when the second lifting platform 310 is docked with the first channel 500, the transfer vehicle 600 can also move within the first channel 500 between the second buffer position 420 and the second lifting platform 310 to transfer the item P1 to be received in between the second buffer position 420 and the second lifting platform 310.

[0189] It should be noted that when the transfer vehicle 600 travels along the first channel 500, it needs to first transfer the item P2 to be retrieved from the first lifting platform 210 to the first buffer position 410 to free up the carrying space of the transfer vehicle 600, so that it can continue to travel along the first channel 500 to the second buffer position 420 to retrieve the item P1 to be retrieved. Therefore, the position of the first buffer position 410 is related to the direction of travel of the transfer vehicle 600 in the first channel 500.

[0190] In some examples, when the transfer vehicle 600 travels along the first lifting platform 210 towards the second lifting platform 310 in the first channel 500, the first buffer position 410 can be positioned relative to the second buffer position 420 and closer to the first lifting platform 210. When the transfer vehicle 600 travels along the second lifting platform 310 towards the first lifting mechanism 200 in the first channel 500, the first buffer position 410 should be positioned relative to the second buffer position 420 and closer to the second lifting platform 310. In this way, when the transfer vehicle 600 travels in the first channel 500, it can reach the first buffer position 410 first to place the item P2 to be retrieved, thereby freeing up carrying space for the next item P1 to be retrieved.

[0191] The technical solution provided in this application embodiment allows the transfer vehicle 600 to transfer the item P2 to be shipped out between the first lifting mechanism 200 and the first buffer position 410, or to transfer the item P1 to be received between the second buffer position 420 and the second lifting mechanism 300. Thus, during the circular transfer of item P, the item P2 to be shipped out and the item P1 to be received are transferred sequentially, improving the efficiency of the transfer vehicle 600 in transferring the item P2 to be shipped out and the item P1 to be received.

[0192] See also Figure 7 When the first lifting platform 210 is lifting the item P, the transfer vehicle 600 can transfer the item P2 to be shipped out through the following process based on the warehousing system provided in some embodiments of this application.

[0193] When the first lifting platform 210 is connected to the second channel 130 of the storage layer 110, the transfer vehicle 600 located in the storage layer 110 can carry the item P2 to be shipped out through the second channel 130 to the first lifting platform 210, place the item P2 to be shipped out in the first lifting platform 210, and then move from the first lifting mechanism 600 to the second channel 130 to transfer the item P2 to be shipped out from the storage location 120 to the first lifting platform 210.

[0194] Next, the first lifting platform 210 can lift and lower the item P2 to be retrieved, so as to transfer the item P2 from any storage layer 110 of the vehicle 100 to the bottom of the vehicle 100. At this time, the first lifting platform 210 docks with the first channel 500.

[0195] Next, with the first lifting platform 210 connected to the first channel 500, the transfer vehicle 600 located within the first channel 500 can move from the first channel 500 to the first lifting platform 210 and retrieve the item P2 to be shipped from the first lifting platform 210. Then, the transfer vehicle 600 carries the item P2 from the first lifting platform 210 through the first channel 500 to the first buffer position 410, and places the item P2 in the first buffer position 410, thereby transferring the item P2 from the first lifting platform 210 to the first buffer position 410.

[0196] The technical solution provided in this application embodiment allows the first lifting platform 210 to lift and lower the item P2 to be shipped out. The transfer vehicle 600 does not need to move with the first lifting platform 210, so that the transfer vehicle 600 located in the storage layer 110 can transfer the item P2 to be shipped out between the storage location 120 and the first lifting platform 210, and the transfer vehicle 600 located in the first channel 500 can transfer the item P2 to be shipped out between the first lifting platform 210 and the first buffer location 410. This shortens the path length traveled by each transfer vehicle 600 when transferring the item P2 to be shipped out, and improves the transfer efficiency of the transfer vehicle 600 in transferring the item P2 to be shipped out.

[0197] After the item P2 to be shipped out is transferred to the first buffer position 410, and the second lifting platform 310 lifts and lowers the item P, the transfer vehicle 600 can transfer the item P1 to be received into the warehouse through the following process based on the warehousing system provided in some embodiments of this application.

[0198] The transfer vehicle 600 can travel from the first buffer position 410 through the first channel 500 to the second buffer position 420 to retrieve the item P1 to be stored in the second buffer position 420. When the second lifting platform 310 is connected to the first channel 500, the transfer vehicle 600 can travel from the second buffer position 420 through the first channel 500 to the second lifting platform 310 to transfer the item P1 to be stored from the second buffer position 420 to the second lifting platform 310.

[0199] Next, the second lifting platform 310 can lift the item P2 to be taken out, so as to transfer the item P1 to be taken in from the bottom of the vehicle 100 to any storage layer 110 of the vehicle 100. At this time, the second lifting platform 310 is connected to the second channel 130.

[0200] Next, with the second lifting platform 310 connected to the second channel 130, the transfer vehicle 600 located in the storage layer 110 can travel from the second channel 130 to enter the second lifting platform 310 and retrieve the item P1 to be stored on the second lifting platform 310. Then, the transfer vehicle 600 can transfer the item P1 from the second lifting platform 310 to the storage location 120 via the second channel 130 to complete the storage of the item P1.

[0201] The technical solution provided in this application embodiment allows the second lifting platform 310 to lift and lower the item P1 to be stored. The transfer vehicle 600 can move independently of the second lifting platform 310, enabling the transfer vehicle 600 located in the storage layer 110 to transfer the item P1 to be stored between the second lifting platform 310 and the storage location 120. It also enables the transfer vehicle 600 located in the first channel 500 to transfer the item P2 to be released between the second buffer location 420 and the second lifting platform 310. This shortens the path length traveled by each transfer vehicle 600 when transferring the item P1 to be stored, thereby improving the transfer efficiency of the transfer vehicle 600 in transferring the item P1 to be stored.

[0202] Figure 8 This is a top view of a second embodiment of a transfer vehicle looping to transfer items, as described in some embodiments of this application.

[0203] See Figure 8 When the first lifting platform 210 lifts and lowers the transfer vehicle 600 carrying the item P, the transfer vehicle 600 can transfer the item P2 to be shipped out through the following process based on the warehousing system provided in some embodiments of this application.

[0204] In some examples, Figure 8 The structure inside the dashed box is located at the bottom of vehicle 100.

[0205] When the first lifting platform 210 is connected to the second channel 130 of the storage layer 110, the transfer vehicle 600 located in the storage layer 110 can carry the item P2 to be taken out of the warehouse through the second channel 130 to the first lifting platform 210.

[0206] Next, the first lifting platform 210 can lift and lower the transfer vehicle 600 carrying the item P2 to be shipped out, so as to transfer the item P2 to be shipped out from any storage layer 110 of the vehicle 100 to the bottom of the vehicle 100. At this time, the first lifting platform 210 docks with the first channel 500.

[0207] Next, with the first lifting platform 210 and the first channel 500 connected, the transfer vehicle 600 located in the first lifting mechanism 500 can carry the item P2 to be shipped out through the first channel 500 from the first lifting platform 210 to the first buffer position 410, and place the item P2 to be shipped out in the first buffer position 410, so as to transfer the item P2 to be shipped out from the first lifting platform 210 to the first buffer position 410.

[0208] The technical solution provided in this application embodiment allows the transfer vehicle 600 to carry the item P2 to be shipped out, following the lifting platform 210 as it rises and falls. When the first lifting platform 210 docks with the first channel 500, the transfer vehicle 600 can directly carry the item P2 from the first lifting platform 210 to the first channel 500, thereby reducing the number of docking operations when multiple transfer vehicles 600 transfer the item P2 between the first lifting platform 210 and the first channel 500, and improving the efficiency of the transfer vehicle 600 in transferring the item P2.

[0209] See also Figure 8 After the transfer vehicle 600 transfers the item P2 to be shipped from the first lifting platform 210 to the first buffer position 410, based on the warehousing system provided in some embodiments of this application, the transfer vehicle 600 can transfer the item P1 to be received through the following process.

[0210] The transfer vehicle 600 can travel from the first channel 500 to the second buffer position 420 to retrieve the item P1 to be stored in the second buffer position 420. Then, with the second lifting platform 310 docked with the first channel 500, the transfer vehicle 600 can carry the item P1 to be stored from the second buffer position 420 to the second lifting platform 310 to transfer the item P1 from the second buffer position 420 to the second lifting platform 310.

[0211] Next, the second lifting platform 310 can lift the transfer vehicle 600 carrying the item P2 to be shipped out, so as to transfer the item P1 to be shipped in from the bottom of the vehicle 100 to any storage layer 110 of the vehicle 100. At this time, the second lifting platform 310 docks with the second channel 130.

[0212] Next, with the second lifting platform 310 connected to the second channel 130, the transfer vehicle 600 carrying the item P1 to be stored can travel from the second lifting platform 310 to the storage location 120 via the second channel 130 to transfer the item P1 to the storage location 120, thus completing the storage process.

[0213] The technical solution provided in this application embodiment allows the transfer vehicle 600 to carry the item P1 to be stored and follow the second lifting platform 310 up and down. When the second lifting platform 310 docks with the first channel 500, the transfer vehicle 600 can directly carry the item P1 from the first channel 500 to the second lifting platform 310, thereby reducing the number of docking operations when transferring the item P between the first channel 500 and the second lifting platform 310 and improving the efficiency of the transfer vehicle 600 in transferring the item P2 to be stored out.

[0214] In some examples, one of the lifting mechanisms of the first lifting platform 210 and the second lifting platform 310 carries the item P up and down, while the other lifting mechanism carries the transfer cart 600 carrying the item P up and down. For example, the first lifting platform 210 can carry the item P2 to be shipped out, and the second lifting platform 310 can carry the transfer cart 600 carrying the item P1 to be shipped in.

[0215] This application embodiment is only used as an example to illustrate the lifting and lowering of the first lifting platform 210 and the second lifting platform 310 carrying the item P. In another example, the first lifting platform 210 and the second lifting platform 310 can also carry the transfer vehicle 600 carrying the item P. The specific implementation method can be referred to the foregoing embodiment, and will not be repeated here.

[0216] See also Figure 7 and Figure 8 In some examples, the first lifting platform 210 is provided with a first platform track 220, which can dock with the guide track 140. When the first lifting platform 210 docks with the second channel 130 of the reservoir 110, the first platform track 220 docks with the guide track 140 within the second channel 130. In this way, the transfer vehicle 600 can travel from the second channel 130 to the first lifting platform 210, or leave the first lifting platform 210, via the docked guide track 140 and the first platform track 220.

[0217] In some examples, when the first lifting platform 210 is connected to the first channel 500, the first platform track 220 can also be connected to the transport track 510 within the first channel 500. In this way, the transfer vehicle 600 can travel from the first channel 500 to the first lifting platform 210, or leave the first lifting platform 210, via the connected transport track 510 and the first platform track 220.

[0218] In some examples, the second lifting platform 310 is provided with a second platform track 320, which can dock with the guide track 140. When the second lifting platform 310 docks with the second channel 130 of the reservoir 110, the second lifting platform 310 docks with the guide track 140 within the second channel 130. In this way, the transfer vehicle 600 can travel from the second channel 130 to the second lifting platform 310, or exit from the second lifting platform 310, via the docked guide track 140 and the second lifting platform 310.

[0219] In some examples, where the second lifting platform 310 is connected to the first channel 500, the second platform track 320 can also be connected to the transport track 510 within the first channel 500. In this way, the transfer vehicle 600 can travel from the first channel 500 to the second lifting platform 310, or exit from the second lifting platform 310, via the connected transport track 510 and the second platform track 320.

[0220] In some examples, platform track 220 may include a protrusion that matches guide track 140, and the hub of transfer vehicle 600 or a groove provided at the bottom of transfer vehicle 600 may slide into the protrusion of platform track 220 so that transfer vehicle 600 may enter or leave guide track 140 along platform track 220 when guide track 140 and platform track 220 are docked.

[0221] In some examples, platform track 220 may include a raised structure that matches transport track 510, and the hub of transfer vehicle 600 or a groove provided at the bottom of transfer vehicle 600 may slide into the raised structure of transport track 510 so that transfer vehicle 600 may enter or leave transport track 510 along platform track 220 when transport track 510 and platform track 220 are docked.

[0222] The first channel 500 and the second channel 130 can be located on different sides of the first lifting platform 210 and the second lifting platform 310, respectively. Therefore, the two ends of the first platform track 220 and the second platform track 320 can extend in different directions. Taking the first platform track 220 extending in different directions as an example, one side of the first platform track 220 can extend along the docking direction of the second channel 130, and the other side of the first platform track 220 can extend along the docking direction of the first channel 500. The extension method of the second platform track 320 can refer to the extension method of the first platform track 220, and will not be repeated here.

[0223] In some examples, the first platform track 220 and the second platform track 320 can also be arranged in a grid pattern. The guide track 140 or transport track 510 can dock with the grid-arranged first platform track 220 and / or second platform track 320 from four different directions to improve the flexibility of docking the guide track 140 with the first platform track 220 and / or second platform track 320.

[0224] In some examples, the hubs of the transfer vehicle 600 can be drive wheels independently controlled by dual motors, enabling the transfer vehicle 600 to move bidirectionally within the second channel 130 and the first channel 500. When the drive wheels output positive torque, the transfer vehicle 600 travels in one direction within the second channel 130 or the first channel 500. When the drive wheels output reverse torque, the transfer vehicle 600 travels in the other direction within the second channel 130 or the first channel 500.

[0225] Figure 9 This is a top view of the loop transfer path of the warehousing system in some embodiments of this application.

[0226] See Figure 9 In some examples, the first lifting mechanism 200 and the second lifting mechanism 300 may be respectively located in the tunnel between different vehicles 100 and at a certain distance from both ends of the tunnel. The first passage 500 located in the tunnel may extend along both ends of the tunnel and connect with at least two sides of the first lifting mechanism 200 and the second lifting mechanism 300.

[0227] In some examples, buffer positions 400 can be positioned opposite each other on both sides of the vehicle 100 and dock with the first channel 500 according to the extension direction of the passageway, enabling bidirectional or circumferential transfer of item P. Each buffer position 400 on each side of the vehicle 100 can include a first buffer position 410 and a second buffer position 420. One extension direction of the first channel 500 docks with the first buffer position 410, and the other extension direction of the first channel 500 docks with the second buffer position 420.

[0228] In some examples, the first lifting platform 210 can be accessed via a first channel 500 in an extending direction (e.g., Figure 9 The first channel 500 located below the first lifting platform 210 is connected to the first buffer position 410, and can also be connected through the first channel 500 in another extending direction (such as... Figure 9 The first channel 500 located above the first lifting platform 210 connects to the second buffer position 420. The second lifting platform 310 can be connected to the first channel 500 (e.g., in an extending direction) via an extension direction. Figure 9The first channel 500 located below the second lifting platform 310 connects to the second buffer position 420, and can also be connected via the first channel 500 in another extending direction (such as...). Figure 9 The first channel 500, located above the second lifting platform 310, is connected to the first buffer position 410.

[0229] Figure 10 This is a top view of a transfer vehicle moving items between a lifting mechanism and a buffer position in some embodiments of this application.

[0230] In some examples, Figure 10 The structure between the two dashed boxes is located at the bottom of vehicle 100.

[0231] See Figure 10 In some examples, the transfer vehicle 600 can carry the item P2 to be shipped from the first lifting platform 210 through the first passage 500 on one side of the first lifting platform 210 to the first buffer position 410 on the side of the vehicle 100 (e.g. Figure 10 The first buffer position 410 below the first lifting mechanism 200 shown is used to transfer the item P2 to be retrieved from the first lifting platform 210 to the first buffer position 410.

[0232] Then, the transfer vehicle 600 can travel from the first buffer position 410 on one side of the vehicle 100 through the first channel 500 to the second buffer position 420 on the other side of the vehicle 100 (e.g., Figure 10 The second buffer position 420 below the second lifting mechanism 300 is shown to retrieve the item P1 to be stored in the second buffer position 420. Next, the transfer vehicle 600 can carry the item P1 to be stored through the first passage 500 on one side of the second lifting platform 310 from the second buffer position 420 to the second lifting platform 310, and place the item P1 to be stored on the second lifting platform 310 to transfer the item P1 from the second buffer position 420 to the second lifting platform 310.

[0233] Next, the transfer vehicle 600 can retrieve the item P2 to be shipped out from the second lifting platform 310 and continue moving along it to travel from the first passage 500 on the other side of the second lifting platform 310 to the first buffer position 410 on the other side of the vehicle 100 (e.g., Figure 10 The first buffer position 410 above the second lifting mechanism 300 (shown) is used to transfer the item P2 to be retrieved from the second lifting platform 310 to the first buffer position 410.

[0234] Then, the transfer vehicle 600 can travel from the first buffer position 410 on the other side of the vehicle 100 through the first channel 500 to the second buffer position 420 on the other side of the vehicle (e.g., Figure 10The second buffer position 420 above the first lifting mechanism 200 is used to retrieve the item P1 to be stored in the second buffer position 420. Next, the transfer vehicle 600 can travel from the second buffer position 420 through the first passage 500 on the other side of the second lifting platform 310 to the first lifting platform 210 to transfer the item P2 to be stored from the second buffer position 420 to the first lifting platform 210, thereby transporting the item P in a loop.

[0235] It should be noted that this application uses the example of a transfer vehicle 600 transferring item P counterclockwise in a circular transport path as an example. In the circular transport path, the transfer vehicle 600 can also transfer item P clockwise, or it can transfer item P circumferentially within the first lifting platform 210, the buffer space 400 located on either side of the vehicle 100, the second lifting platform 310, and the vehicle 100, either counterclockwise or clockwise. The transfer vehicle 600 can use any one of the above-mentioned circular transfer methods or a combination of multiple circular transfer methods to transfer items P to be stored and items P to be shipped out.

[0236] The technical solution provided in this application embodiment involves a first lifting mechanism 200 and a second lifting mechanism 300 respectively positioned between different carriers 100 and at certain distances from both ends of the tunnel. A transfer vehicle 600 can move items P along the first channel 500 in two extending directions within the tunnel, between the first lifting mechanism 200, the second lifting mechanism 300, and buffer positions 400 at different locations, providing multiple paths for the transfer vehicle 600 to move items P. The transfer vehicle 600 can form a circumferential transfer between the first lifting mechanism 200 and the second lifting mechanism 300. During the circumferential transfer, the transfer vehicle 600 can move items P multiple times between buffer positions 400 at different locations and between different lifting mechanisms, improving the transfer efficiency of items P.

[0237] Figure 11 This is a diagram showing the internal structure of the cache bits in some embodiments of the storage system in this application. Figure 12 This is a structural diagram of a transfer vehicle carrying items into a buffer location in some embodiments of this application.

[0238] See Figure 11 In some implementations, the cache position 400 includes a post 430 and a clamping part 440 disposed on the post 430. Multiple posts 430 enclose a storage space for placing an item P.

[0239] In some examples, the clamping part 440 can be a plate-like structure or a rod-like structure, and the cross-section of the clamping part 440 matches the cross-section of the transport track 510 in the first channel 500.

[0240] In some examples, the transport track 510 may dock with the clamping part 440. When the transfer car 600 enters the buffer position 400 from the first channel 500, it travels to the buffer position 400 via the transport track 510 and the clamping part 440. Inside the buffer position 400, the clamping parts 440 provided on the columns 430 on both sides respectively support different positions of the transfer car 600, such as the left and right sides, or the front and rear ends, so as to clamp the transfer car 600 above the clamping part 440.

[0241] In some examples, in order to facilitate clamping the transfer cart 600 and carrying the item P, the clamping parts 440 of multiple columns 430 can all be located at the same height to horizontally support the transfer cart 600 and prevent the item P from falling.

[0242] The technical solution provided in this application embodiment allows the transfer cart 600 to be clamped by the clamping part 440 provided on the column 430, so as to support the transfer cart 600 in the buffer position 400, so that the transfer cart 600 can stably pick up or place the item P in the buffer position 400, thereby improving the stability of the transfer of the item P between the transfer cart 600 and the buffer position 400.

[0243] See in some examples Figure 12 The top of the transfer vehicle 600 is equipped with a first picking mechanism 610, which can be raised and lowered along the height of the transfer vehicle 600. When the transfer vehicle 600 is unloaded, the first picking mechanism 610 is folded and retracted inside the transfer vehicle 600. When the transfer vehicle 600 is carrying item P, the first picking mechanism 610 is raised.

[0244] In some examples, during the transfer of item P from the first lifting mechanism 200 to the buffer position 400, the transfer cart 600 can travel from the transport track 510 to the buffer position 400, while the first picking mechanism 610 remains raised. After the transfer cart 600 enters the buffer position 400, it can proceed as follows: Figure 12 The arrow indicates that the first picking mechanism 610 is retracted to place the item P from the first picking mechanism 610 above the clamping part 440.

[0245] In some examples, when the first picking mechanism 610 is fully retracted into the transfer vehicle 600, the top of the clamping part 440 is in direct contact with the bottom of the item P to fully support the item P.

[0246] In some examples, during the transfer of item P from buffer position 400 to the second lifting mechanism 300, the empty transfer cart 600 travels from transport track 510 to enter the buffer position 400 where item P is placed, while the first picking mechanism 610 remains folded. After the transfer cart 600 enters the buffer position 400, the first picking mechanism 610 can be raised to lift item P from the clamping part 440, allowing item P to be carried by the first picking mechanism 610 and transferred from the buffer position 400 to the transfer cart 600. The transfer cart 600 can maintain the first picking mechanism 610 in the raised state and travel from the buffer position 400 to transport track 510 to leave the buffer position 400.

[0247] In some examples, the clamping part 440 is provided with clamping protrusions 441 for better clamping of the transfer cart 600, see further. Figure 11 The clamping protrusions 441 are located on opposite sides of each clamping part 440. When the transfer carriage 600 enters the buffer position 400, the clamping protrusions 441 engage with the bottom edge of the transfer carriage 600, and the side of the clamping part 440 fits against the side of the transfer carriage 600.

[0248] The technical solution provided in this application embodiment improves the stability of the transfer cart 600 in the buffer position 400 by providing a clamping protrusion 441 on the clamping part 440 and using the clamping protrusion 441 to support the transfer cart 600. Simultaneously, the side of the clamping part 440 fits against the side of the transfer cart 600, so that the transfer cart 600 moves along the docking direction between the transport track 510 and the clamping part 440 when entering and exiting the buffer position 400, reducing the movement deviation of the transfer cart 600 and improving the movement accuracy of the transfer cart 600 when transferring the item P.

[0249] In some examples, the item P2 to be shipped from the buffer position 400 can be moved out of the storage area from the side of the buffer position 400 away from the storage area to complete the shipment. For this purpose, the storage system also includes a third channel 700 and a transport robot 800. The third channel 700 is located below the gripping part 440.

[0250] Figure 13 This is a structural diagram of a transport robot entering a buffer location containing items, as shown in some embodiments of this application.

[0251] See Figure 13 In some examples, transport robot 800 can dock with third channel 700 and carry item P in and out of buffer position 400 to transfer item P between buffer position 400 and transport robot 800.

[0252] In some examples, the transport robot 800 operates in a picking area located outside the storage area, which includes an inbound area and an outbound area.

[0253] In some examples, the receiving area is the area where the item P1 to be received is placed. The transport robot 800 can move between the receiving area and the buffer position 400 to transfer the item P1 to be received between the receiving area and the buffer position 400.

[0254] In some examples, the outbound area is the area where the item P2 to be outbound is placed. The transport robot 800 can move between the buffer position 400 and the outbound area to transfer the item P2 to be outbound between the buffer position 400 and the outbound area.

[0255] In some examples, transport robot 800 retrieves item P1 from the receiving area and carries it towards buffer position 400, thereby docking with the third channel 700 of buffer position 400. With transport robot 800 docked with the third channel 700, it can carry item P from the third channel 700 to buffer position 400 to place item P in buffer position 400, allowing it to be transferred between buffer position 400 and storage location 120 via transfer vehicle 600.

[0256] In some examples, when the transport robot 800 docks with the third channel 700, the transport robot 800 walks from the third channel 700 to the buffer position 400, picks up the item P placed in the buffer position 400, walks from the buffer position 400 back to the third channel 700 to return to the picking area, and transfers the item P to the outbound area.

[0257] Figure 14 This is a structural diagram of a transport robot retrieving items from a buffer location in some embodiments of this application.

[0258] See in some examples Figure 14 The transport robot 800 has a second picking mechanism 810 on its top for picking up and placing items P. The second picking mechanism 810 carries items P when it is in the raised state.

[0259] In some examples, the transport robot 800 can transfer item P inside and outside the storage area via the buffer position 400 and the transfer cart 600. After the transfer cart 600 places item P above the gripping part 440, the transfer cart 600 can move from the buffer position 400 to the first channel 500 to leave the buffer position 400. Then, the transport robot 800 can move from the third channel 700 to the buffer position 400, reaching directly below item P, and raise the second picking mechanism 810. The second picking mechanism 810 can rise from the gap between the gripping parts 440 and lift item P from below to retrieve item P, and then leave the buffer position 400 through the third channel 700 to transfer item P out of the buffer position 400.

[0260] In this embodiment, the transfer vehicle 600 and the transport robot 800 transfer the item P through the buffer position 400, enabling the item P to be transferred inside and outside the storage area without going through a transport line, thereby saving the equipment cost of setting up a transport line. Simultaneously, the transfer vehicle 600 enters and exits the buffer position 400 through the docking between the transport track 510 and the clamping part 440, while the transport robot 800 enters and exits the buffer position 400 through the third channel 700 located below the clamping part 440. The transfer vehicle 600 and the transport robot 800 can enter and exit the buffer position 400 at different heights without interfering with each other, thereby improving the stability of transferring the item P between the transfer vehicle 600, the buffer position 400, and the transport robot 800.

[0261] Based on the above-described warehousing system, some embodiments of this application also provide a carrier 100, including a multi-layer storage layer 110 arranged along the height direction. The storage layer 110 is provided with storage locations 120 and a second channel 130. The storage locations 120 can be distributed along both sides of the second channel 130 for placing items P. The second channel 130 can penetrate through the length or width of the storage layer 110, forming a path for a transfer vehicle 600 to move horizontally within the storage layer 110.

[0262] Storage layer 110 can connect to first lifting mechanism 200 via second channel 130, allowing transfer vehicle 600 to transfer item P2 to be retrieved between storage location 120 and first lifting mechanism 200 via second channel 130. For example, transfer vehicle 600 can travel from second channel 130 to storage location 120 to retrieve item P2. Then, transfer vehicle 600 carrying item P2 can travel from storage location 120 to first lifting mechanism 200 via second channel 130 and place item P2 in first lifting mechanism 200 to transfer item P2 from storage location 120 to first lifting mechanism 200.

[0263] Storage layer 110 can also connect to second lifting mechanism 300 via second channel 130, allowing transfer vehicle 600 to transfer item P1 to be stored between second lifting mechanism 300 and storage location 120 via second channel 130. For example, transfer vehicle 600 can travel from second channel 130 to enter second lifting mechanism 300 to retrieve item P1 to be stored carried by second lifting mechanism 300. Then, transfer vehicle 600 carrying item P1 to be stored can travel from second lifting mechanism 300 to storage location 120 via second channel 130 and place item P1 to be stored in storage location 120 to transfer item P1 from storage location 120 to second lifting mechanism 300.
