[0022] In this application, all the accompanying drawings are schematic drawings, used only to illustrate the principle of the present invention, and are not necessarily drawn to scale. Detailed Implementation

[0023] The present invention will now be described with reference to the accompanying drawings.

[0024] In the following description, some details of the present invention are provided to better understand the technical solution of the present invention. However, those skilled in the art will understand that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0025] According to one aspect of the present invention, a conveying device is provided. The conveying device can remove items from storage operation positions on storage racks and transport them to a target location, or place items into target storage operation positions on storage racks. The conveying device can be applied to any suitable equipment, including but not limited to warehousing systems. The conveying device of embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figures 2 to 4 as well as Figure 6 As shown, the conveying device can be installed on the side of the storage rack 900. The storage rack 900 has a plurality of storage operation positions 901 arranged in an array in a vertical plane, each of which can hold items. The storage rack 900 may have a first side and a second side opposite each other along a first horizontal direction YY, and an upper side and a lower side opposite each other along a longitudinal direction ZZ. The first horizontal direction YY may be perpendicular to the second horizontal direction XX and the longitudinal direction ZZ. The storage rack 900 may have a storage and retrieval operation surface 902 facing the conveying device 800. The storage and retrieval operation surface 902 may be parallel to the plane defined by the longitudinal beam 100 and the transverse beam 700 (i.e., the plane defined by the second horizontal direction XX and the longitudinal direction ZZ), therefore, the first horizontal direction YY may be perpendicular to the storage and retrieval operation surface 902 of the storage rack 900. The conveying device 800 may be installed on at least one of the first side and the second side.

[0027] In this embodiment, the conveying device 800 may include longitudinal beams 100. The longitudinal beams 100 may include at least one, for example, one, two, or more. Each longitudinal beam 100 may extend along the longitudinal direction ZZ. In embodiments with multiple longitudinal beams 100, the multiple longitudinal beams 100 may be arranged along a second horizontal direction XX. The second horizontal direction XX may be perpendicular to the longitudinal direction ZZ, and the plane containing both the second horizontal direction XX and the longitudinal direction ZZ is the operating surface of the storage rack. The longitudinal beams 100 may be made of any suitable material such as aluminum or steel.

[0028] Exemplarily, the transmission device 800 may further include a transverse beam 700. The transverse beam 700 may extend along a second horizontal direction XX. At least one longitudinal beam 100 may be movable along the transverse beam 700. In embodiments where there are multiple transverse beams 700, the multiple transverse beams 700 may be arranged in a longitudinal direction ZZ. At least one longitudinal beam 100 may be movable along the transverse beam 700. The transverse beam 700 may be made of any suitable material such as aluminum or steel.

[0029] The transfer device 800 may further include a task module 300 and an auxiliary transfer component 400. The task module 300 and the auxiliary transfer component 400 may be connected to at least one longitudinal beam 100. Exemplarily, the task module 300 and the auxiliary transfer component 400 may move along at least one longitudinal beam 100. In embodiments where the transfer device 800 includes a transverse beam 700, the task module 300 and the auxiliary transfer component 400 may move to any position within a plane defined by a second horizontal direction XX and a longitudinal direction ZZ, thereby enabling the handling of more items on storage operation positions 901 on the storage rack 900. Specifically, the auxiliary transfer component 400 may be configured to cooperate with the task module 300 of the transfer device to access items at storage operation positions 901 of the storage rack 900.

[0030] Items may include goods and / or cartons. Cargo cartons may include one or more of the following: bins that are sized to fit the storage operation position 901 of the storage rack 900, and the original packaging of the goods. Bins may include plastic boxes or cardboard boxes, etc. Original packaging may include one or more of the following: original packaging boxes and original packaging bags, etc. When storing goods by bins, typically only one or more bin sizes are placed on each storage rack 900. When goods in a carton need to be retrieved, the auxiliary transfer component 400 can move the carton from the storage operation position 901 of the storage rack 900 to the task module 300. The target goods can then be manually or by picking device from the cartons on the task module 300, and then the target goods are transported to the target location. Alternatively, the cartons on the task module 300, together with the goods inside, can be transported to the target location by moving the task module 300 along the longitudinal beam 100 and / or by moving the longitudinal beam 100 relative to the transverse beam 700. Optionally, empty boxes on storage operation positions 901 of the storage rack 900 can be moved to the task module 300 to place goods inside the empty boxes. Optionally, when goods are placed directly on storage operation positions 901 of the storage rack 900, the goods on storage operation positions 901 can be moved entirely to the task module 300, and then the task module 300 can transport the goods to the target location. Furthermore, when only goods are being retrieved without removing the boxes, only the boxes can be partially moved to the task module 300, as long as the goods inside can be retrieved. When the task module 300 needs to move the goods or boxes entirely to the target location, the goods or boxes can be completely moved to the task module 300 to avoid interference with the longitudinal beams 100 and / or transverse beams 700 when the task module 300 moves along them. In summary, the working principle of the auxiliary transfer component 400 is similar, whether it is moving empty containers or containers filled with goods to the task module 300, moving goods directly to the task module 300, or moving them from the task module 300 to the storage operation position 901 of the storage rack 900.

[0031] The storage rack 900 may have a storage and retrieval operation surface 902 facing the conveying device 800. The storage and retrieval operation surface 902 may be parallel to the plane defined by the longitudinal beam 100 and the transverse beam 700 (i.e., the plane defined by the second horizontal direction XX and the longitudinal direction ZZ). The auxiliary conveying assembly 400 may perform storage and retrieval actions, i.e., take out or store items, at the storage operation position 901 via the storage and retrieval operation surface 902.

[0032] At least one side of the task module 300 and the auxiliary transmission component 400, located opposite each other along the second horizontal direction XX, can be connected to the longitudinal beam 100. Exemplarily, when only one longitudinal beam 100 is included, one side of the task module 300 and the auxiliary transmission component 400, located opposite each other along the second horizontal direction XX, can be connected to the longitudinal beam 100. Exemplarily, when multiple longitudinal beams 100 are included, the multiple longitudinal beams 100 can be distributed on opposite sides of the task module 300 and the auxiliary transmission component 400 along the second horizontal direction XX. The task module 300 and the auxiliary transmission component 400, located opposite each other along the second horizontal direction XX, can each be connected to a longitudinal beam 100. Of course, when multiple longitudinal beams 100 are included, the multiple longitudinal beams 100 can also be arranged on one side of the task module 300 and the auxiliary transmission component 400. The method for driving the task module 300 and the auxiliary transmission component 400 to move along at least one longitudinal beam 100 can be arbitrary, for example, it can be a manual method, a motor-driven method, or a cylinder-driven method.

[0033] Task module 300 may include a space for placing items. An auxiliary transfer component 400 may be located above the space for placing items. The auxiliary transfer component 400 may be used to move items between the space for placing items and the storage operation position 901 on the storage rack 900. Task module 300 may have the function of supporting items. Task module 300 may also have the function of securing items by clamping or other means. Task module 300 may be a supporting component, an automated guided vehicle (AGV), or a storage robot. For example, task module 300 may include a supporting component. The supporting component may include a supporting position 301. The supporting position 301 may be used to support items. The auxiliary transfer component 400 may be used to move items between the supporting position 301 of the supporting component and the storage operation position 901 on the storage rack 900. The supporting position 301 may be located at any suitable position on the supporting component. Exemplarily, the top surface of the supporting component can be configured to support items, i.e., the supporting position 301 can include the space above the top surface of the supporting component; alternatively, the supporting component can be configured to have a storage compartment for placing items, and the supporting position 301 can include the space inside the storage compartment. Exemplarily, the supporting component can include a top wall, a bottom wall, and side walls that are interconnected to form a passage-like storage compartment. The entrance and exit of the passage can face the storage rack 900, allowing items to move between the storage operation position 901 and the supporting position 301 on the storage rack 900.

[0034] The auxiliary transmission component 400 and the task module 300 can be spaced apart. Exemplarily, the auxiliary transmission component 400 and the task module 300 can be completely spaced apart without any connecting parts between them. In this embodiment, the auxiliary transmission component 400 and the task module 300 can each be connected to at least one longitudinal beam 100. Exemplarily, a connector, such as a bracket or column, can be used to connect the spaced-apart auxiliary transmission component 400 and the task module 300 to separate them. In this embodiment, one of the auxiliary transmission component 400 and the task module 300 can be connected to the longitudinal beam 100. Along the longitudinal direction ZZ, the auxiliary transmission component 400 can be located above the task module 300. Thus, the auxiliary transmission component 400 no longer interferes with the task module 300. Although in the illustrated embodiment, the auxiliary transmission component 400 is located directly above the task module 300, in other embodiments not shown, the auxiliary transmission component 400 can be located diagonally above the task module 300, as long as the auxiliary transmission component 400 is above the task module 300. The auxiliary transfer component 400 can be used to move items between the task module 300 and the storage operation position 901 on the storage rack 900. The auxiliary transfer component 400 can engage with items in any suitable manner, such as through suction cups, clamps, hooks, or magnetic attraction, to achieve the purpose of moving items. Accordingly, the items can have an adapter structure that is compatible with the auxiliary transfer component 400. For example, when the auxiliary transfer component 400 uses a hook to engage the items, the items can be provided with a handle or groove, or other adapter structure, for engaging with the hook of the auxiliary transfer component 400. The auxiliary transfer component 400 can then engage with this adapter structure to move the items.

[0035] In embodiments where the auxiliary transmission component 400 and the task module 300 are completely separated and there is no connecting element between them, such as Figure 6 As shown, the task module 300 is configured to move along the operating surface of the storage rack 900 (i.e., the access operating surface 902 of the storage rack 900), and also to move away from the operating surface along the travel surface (i.e., the lower platform 1 where the storage rack 900 is located). The travel surface can be an aisle, a non-ground lower platform, or a plane between storage racks for the guide vehicle (task module 300) to travel on.

[0036] In an embodiment where the auxiliary transfer component 400 and the task module 300 are completely separated and there is no connecting element between them, the auxiliary transfer component 400 is configured to move along the operating surface of the storage rack 900 (i.e., the access operating surface 902 of the storage rack 900) and also to move away from the operating surface along the travel surface (i.e., the lower platform 1 where the storage rack 900 is located). The travel surface can be an aisle, a non-ground lower platform, or a plane between storage racks for the auxiliary transfer component 400 to travel on.

[0037] In another embodiment, the auxiliary transfer component 400 can be mounted on the AGV. For example, the auxiliary transfer component 400 and the task module 300 are fixedly connected by a connector.

[0038] Furthermore, a space is provided between the storage rack 900 and the lower platform 1 for the task module 300 to move. That is, the height between the bottom of the storage rack 900 and the lower platform 1 is greater than the height of the task module 300 that carries the boxes or goods, thereby allowing the task module 300 to pass through the space between the storage rack 900 and the lower platform 1 during its movement on the lower platform 1.

[0039] According to this utility model, in one embodiment, such as Figure 6 As shown, the task module 300 mainly includes a cargo robot body 51 and a climbing mechanism 52. The support position 301 of the support component is provided on the cargo robot body 51. The climbing mechanism 52 is provided on the side of the cargo robot body 51. The climbing mechanism 52 can dock with the longitudinal beam 100 and can move along the longitudinal beam 100, thereby enabling the entire task module 300 to move along the longitudinal beam 100.

[0040] Specifically, such as Figure 7 As shown, the climbing mechanism 52 is disposed on the side of the cargo robot body 51, and the climbing mechanism 52 is vertically movable on the cargo robot body 51. That is, the climbing mechanism 52 can move up and down relative to the cargo robot body 51, thereby adjusting the height of the climbing mechanism 52. The climbing mechanism 52 mainly includes a climbing driver (not shown in the figure) and a docking mechanism 522, and the climbing driver can drive the docking mechanism 522. When the task module 300 needs to move vertically along the longitudinal beam 100, the task module 300 first moves on the lower platform 1 to the vicinity of the longitudinal beam 100 until the climbing mechanism 52 is located below the longitudinal beam 100. Then, the climbing mechanism 52 moves upward relative to the cargo robot body 51 until the docking mechanism 522 docks with the longitudinal beam 100. In this embodiment, the docking mechanism 522 docks with the longitudinal beam 100 by meshing. Start the climbing drive, which drives the docking mechanism 522 to rotate. The docking mechanism 522 moves along the longitudinal beam 100 through meshing, thereby causing the task module 300 to move along the longitudinal beam 100.

[0041] In a specific embodiment, such as Figure 7 and Figure 8 As shown, the docking mechanism 522 mainly includes a support frame 525, a sprocket 523, and a guide block 521.

[0042] The support frame 525 is vertically movable on the cargo robot body 51. The support frame 525 is connected to the lifting drive (not shown in the figure), meaning that after the lifting drive is activated, it can drive the support frame 525 to move up and down relative to the cargo robot body 51. The structure of the support frame 525 being movable on the cargo robot body 51 and connected to the lifting drive is well known to those skilled in the art and will not be described in detail here.

[0043] The sprocket 523 is rotatably mounted on the upper end of the support frame 525. The rotation axis of the sprocket 523 is set in the horizontal direction, and the sprocket 523 is driven by the climbing driver, that is, the climbing driver can drive the sprocket 523 to rotate.

[0044] Guide blocks 521 are fixedly mounted on the upper end of the support frame 525, and two guide blocks 521 are symmetrically arranged on both sides of the sprocket 523. Guide blocks 521 can be movably connected to the longitudinal beam 100.

[0045] A chain 524 for engaging with a sprocket 523 is provided vertically on the longitudinal beam 100.

[0046] In this setup, when the task module 300, moving on the lower platform 1, needs to dock with the longitudinal beam 100, the task module 300 first moves to the vicinity of the longitudinal beam 100 until the guide block 521 is located below the longitudinal beam 100. Then, the lifting driver drives the support frame 525 to move upward relative to the cargo robot body 51, thereby causing the guide block 521 and the sprocket 523 to move upward relative to the cargo robot body 51. Finally, the guide block 521 and the longitudinal beam 100 are fitted together to form a sliding pair, and the sprocket 523 meshes with the chain 524. At this time, the climbing driver is activated, thereby driving the sprocket 523 to rotate. Under the meshing action of the sprocket 523 and the chain 524, the task module 300 moves up and down along the longitudinal beam 100.

[0047] Although the docking mechanism 522 in this embodiment docks with the longitudinal beam 100 by meshing the sprocket 523 and the chain 524, this is not intended to limit the scope of protection of this utility model. Other ways to achieve docking between the docking mechanism 522 and the longitudinal beam 100 should also be within the scope of protection of this utility model. For example, the sprocket 523 and the chain 524 in this embodiment can be replaced with meshing gears and racks, or with pulleys and belts that generate rolling friction.

[0048] In an embodiment where the auxiliary transmission component 400 is configured to be able to move along the operating surface of the storage rack 900 (i.e., the access operating surface 902 of the storage rack 900) and also to move away from the operating surface along the walking surface (i.e., the lower platform 1 where the storage rack 900 is located), the corresponding structure of the auxiliary transmission component 400 can refer to the structure of the aforementioned task module 300.

[0049] In embodiments where the auxiliary transfer component 400 is configured to move along the operating surface of the storage rack 900 (i.e., the access operating surface 902 of the storage rack 900), exemplarily, such as Figures 1 to 5 As shown, the transmission device 800 may further include a first drive assembly 500. The first drive assembly 500 may be disposed on at least one of the at least one longitudinal beam 100. That is, the first drive assembly 500 may be disposed on only one longitudinal beam 100, or the first drive assembly 500 may be disposed on multiple longitudinal beams 100. Specifically, the first drive assembly 500 may include a first driver 510 and a first flexible transmission mechanism. The first flexible transmission mechanism may be connected between the drive end of the first driver 510 and the auxiliary transmission assembly 400. Driven by the first driver 510, the auxiliary transmission assembly 400 may move along at least one longitudinal beam 100.

[0050] The first flexible transmission mechanism includes, but is not limited to, a belt drive mechanism or a chain drive mechanism. Specifically, the first flexible transmission mechanism may include a first wheel 520 and a first annular flexible member 530. The first driver 510 may be disposed on the longitudinal beam 100. The first wheel 520 may include multiple wheels. The first annular flexible member 530 may be tensioned on multiple first wheels 520. The first annular flexible member 530 may include a first longitudinal segment 531 extending ZZ in the longitudinal direction.

[0051] The auxiliary transmission component 400 can be connected to the first longitudinal segment 531. The drive end of the first driver 510 can be connected to at least one of the plurality of first wheels 520 to drive the first wheel 520 to rotate, thereby driving the first annular flexible member 530 to rotate, which in turn drives one of the connected task module 300 and auxiliary transmission component 400 to move in the longitudinal direction ZZ.

[0052] The first driver 510 can employ various types of drivers known in the art or that may emerge in the future, including but not limited to motors or rotary cylinders. The first wheel 520 and the first annular flexible member 530 can be adapted to each other; for example, the first wheel 520 may include a pulley, and the first annular flexible member 530 may include a belt; or, the first wheel 520 may include a sprocket, and the first annular flexible member 530 may include a chain.

[0053] The task module 300 and the auxiliary transfer component 400 can each move independently along at least one longitudinal beam 100. Thus, either the task module 300 or the auxiliary transfer component 400 can adjust their spacing along the longitudinal direction (ZZ) by movement. Furthermore, the task module 300 and the auxiliary transfer component 400 can operate completely independently, unlike in existing technologies where they must work together. For example, after the auxiliary transfer component 400 moves items from storage operation position 901 to the task module 300, the task module 300 can move independently to a transport trolley or manual transfer station without simultaneously moving the auxiliary transfer component 400, thereby reducing energy consumption. During this process, the auxiliary transfer component 400 can remain stationary or move in advance to the next storage operation position 901 to prepare for the next transport step, thereby improving work efficiency.

[0054] Task modules 300 and auxiliary transfer components 400 do not need to be configured in a one-to-one correspondence. Different task modules 300 and auxiliary transfer components 400 can be arbitrarily combined. For example, after auxiliary transfer component 400 moves items from storage operation position 901 to task module 300, auxiliary transfer component 400 can cooperate with other task modules 300 to move items. Similarly, after task module 300 completes the transfer of items, it can also cooperate with other auxiliary transfer components 400 to move items. Thus, the number of task modules 300 and auxiliary transfer components 400 can be different to adapt to different needs. For example, when the path from task module 300 to the handling cart or manual transfer station is long, more task modules 300 can be set up separately. In short, task modules 300 and auxiliary transfer components 400 can have multiple options to meet different logistics needs, thereby improving work efficiency in a targeted manner.

[0055] For example, such as Figures 1 to 5 As shown, the plurality of first wheels 520 may include a first upper wheel 521 and a first lower wheel 522. The first upper wheel 521 and the first lower wheel 522 may be arranged at a ZZ interval along the longitudinal direction. The first upper wheel 521 may be located at the upper end of the longitudinal beam 100 to which it is located. The first lower wheel 522 may be located at the lower end of the longitudinal beam 100 to which it is located. The upper end and the lower end of the first annular flexible member 530 may be respectively fitted onto the first upper wheel 521 and the first lower wheel 522.

[0056] For example, the drive end of the first driver 510 can be connected to a first upper wheel 521, which can be used as a driving wheel, while the other first upper wheels 521 and the first lower wheels 522 can be used as driven wheels.

[0057] A transmission channel 110 may be provided within the longitudinal beam 100. The transmission channel 110 may extend through the longitudinal beam 100 in the longitudinal direction ZZ. Each portion of the first annular flexible member 530 may pass through the transmission channel 110. The first longitudinal segment 531 may be located outside the transmission channel 110 to facilitate connection to the auxiliary transmission assembly 400.

[0058] Exemplarily, the first annular flexible member 530 may further include a third longitudinal segment 532 extending ZZ in the longitudinal direction. The third longitudinal segment 532 may be arranged parallel to and opposite to the first longitudinal segment 531. The first longitudinal segment 531 may be located on the side of the first annular flexible member 530 facing the auxiliary transmission assembly 400, and the third longitudinal segment 532 may be located on the side of the first annular flexible member 530 facing away from the auxiliary transmission assembly 400. The third longitudinal segment 532 may pass through the transmission channel 110.

[0059] For example, such as Figures 1 to 3 As shown, the auxiliary transfer assembly 400 may include a transport body 410, a transport drive mechanism, and a transport component 430. The transport body 410 may be connected to at least one longitudinal beam 100, thereby being movable along at least one longitudinal beam 100.

[0060] For example, along the second horizontal direction XX, both ends of the transport body 410 can be movably connected to the longitudinal beam 100. The transport body 410 includes, but is not limited to, any suitable structure such as a bracket or base. A transport drive mechanism can be mounted on the transport body 410. The drive end of the transport drive mechanism can be connected to the transport component 430 to drive the transport component 430 to transport items between the task module 300 and the storage operation position 901. The transport component 430 can be used as an adapter structure for connecting components to items. The transport drive mechanism includes, but is not limited to, a motor mechanism, a cylinder mechanism, and / or a hydraulic cylinder mechanism. With this configuration, the auxiliary transmission assembly 400 has a simpler structure and is easier to manufacture.

[0061] Exemplarily, the transport drive mechanism may include a movable arm subassembly, a movable arm driver, and a transport driver 423. One end of the movable arm subassembly may be connected to the transport body 410, and the transport driver 423 may be mounted on the other end of the movable arm subassembly, with its drive end connected to the transport member 430. The movable arm subassembly is movable under the drive of the movable arm driver, and the transport member 430 is movable under the drive of the transport driver 423. Under the drive of the movable arm driver, the movable arm subassembly may fold and / or extend, etc., thereby moving the position of the transport member 430 so that the transport member 430 can engage with the item and transport the item.

[0062] For example, such as Figures 1 to 3As shown, the movable arm actuator may include a first movable arm actuator 421 and a second movable arm actuator 422. The movable arm subassembly may include a first movable arm 424 and a second movable arm 425. One end of the first movable arm 424 may be rotatably connected to the conveying body 410. The drive end of the first movable arm actuator 421 may be connected to the first movable arm 424 for driving the first movable arm 424 to rotate about a first axis parallel to the second horizontal direction XX.

[0063] Optionally, one end of the first movable arm 424 can be directly connected to the drive end of the first movable arm driver 421, so that it can be driven to rotate by the first movable arm driver 421. The second movable arm driver 422 can be disposed on the first movable arm 424. The drive end of the second movable arm driver 422 can be connected to the second movable arm 425, so as to drive the second movable arm 425 to rotate about a second axis parallel to the second horizontal direction XX.

[0064] Optionally, the second movable arm 425 can be rotatably connected to the first movable arm 424, or it can be directly connected to the drive end of the second movable arm driver 422. A transport driver 423 can be mounted on the second movable arm 425. The drive end of the transport driver 423 can be connected to the transport member 430 to drive the transport member 430 to rotate about a third axis parallel to the second horizontal direction XX.

[0065] Optionally, the transport component 430 can be rotatably connected to the second movable arm 425, or directly connected to the drive end of the transport driver 423. With this configuration, the transport component 430 has a very high degree of freedom in a plane perpendicular to the second horizontal direction XX, allowing it to rotate to any desired position. This facilitates the adaptation structure between the component and the item for transporting the item. Furthermore, the transport drive mechanism can be configured to drive the transport component 430 to extend to both sides along the first horizontal direction YY outside the task module 300. Thus, the transport drive mechanism can drive the transport component 430 to access the first storage rack 910 and the second storage rack 920 to transport items on the first storage rack 910 and the second storage rack 920.

[0066] The first movable arm driver 421, the second movable arm driver 422, and the transport driver 423 may each include any suitable driver such as a motor or a rotary cylinder. In the illustrated embodiment, the movable arm subassembly includes two movable arms. In other embodiments not shown, the movable arm subassembly may include more or fewer movable arms. With only one movable arm, the length of the transport member 430 can be increased, thereby increasing the range of motion of the transport member 430. Furthermore, in the illustrated embodiment, the rotation axes of each movable arm in the movable arm subassembly and the transport member 430 are parallel to the second horizontal direction XX, but in other embodiments not shown, the rotation axes of each movable arm and the transport member 430 may extend in different directions.

[0067] For example, in an embodiment where the auxiliary transfer component 400 is positioned diagonally above the task module 300, the rotation axis of at least one of the movable arms and the transport component 430 can be substantially parallel to the first horizontal direction YY, enabling the transport of items between the storage operation position 901 of the storage rack 900 and the task module 300. Even if the auxiliary transfer component 400 is positioned directly above the task module 300, the rotation axis of at least one of the movable arms and the transport component 430 does not need to be parallel to the second horizontal direction XX, as long as its transport function is still possible.

[0068] For example, such as Figures 1 to 3 As shown, the transport member 430 may be provided with transport parts 431 for transporting items on both sides along its movement trajectory. The transport parts 431 may be arranged opposite to each other along the rotation direction of the transport member 430. The transport parts 431 may be used to engage with the adapter structure of the item. Thus, the transport part 431 on one side can transport items between the first storage operation position 911 of the first storage rack 910 and the task module 300, while the transport part 431 on the other side can transport items between the second storage operation position 921 of the second storage rack 920 and the task module 300. The transport parts 431 include, but are not limited to, suction cups, grippers, or hooks.

[0069] For example, such as Figures 1 to 3As shown, the handling drive mechanism may include a translation drive sub-mechanism disposed on the handling body 410. The movable arm sub-assembly is movable along a first horizontal direction YY under the drive of the translation drive sub-mechanism. Exemplarily, the translation drive sub-mechanism may include a translation driver 426. The drive end of the translation driver 426 may be connected to the handling member 430 for driving the handling member 430 to move along the first horizontal direction YY. In this way, the travel of the handling member 430 in the first horizontal direction YY can be increased to handle items at a deeper position in the storage rack 900. Furthermore, the handling member 430 can move between the first storage rack 910 and the second storage rack 920 to facilitate the handling of items on the first storage rack 910 and the second storage rack 920.

[0070] In an embodiment where the conveying drive mechanism includes a first movable arm driver 421, the drive end of the translation driver 426 can be connected to the first movable arm driver 421 to drive the first movable arm driver 421, the second movable arm driver 422, the conveying driver 423, the first movable arm 424, the second movable arm 425, and the conveying component 430 to move synchronously along a first horizontal direction YY. The translation driver 426 includes, but is not limited to, a motor or a cylinder.

[0071] For example, the conveying body 410 may be provided with a translation guide rail 411 extending along the first horizontal direction YY. The drive end of the translation driver 426 may be connected to the pulley of the belt drive mechanism 427 to drive the pulley to rotate. A slider 428 may be provided on the belt of the belt drive mechanism 427. The translation driver 426 may drive the belt of the belt drive mechanism 427 to rotate, thereby causing the slider 428 to slide along the translation guide rail 411. The first movable arm driver 421 and / or the first movable arm 424 may be provided on the slider 428. In this way, the movable arm sub-assembly and the movable arm driver, etc., can move along the first horizontal direction YY with the slider 428.

[0072] In the above embodiments, by providing more movable arms and / or a translation drive submechanism, the transport stroke of the transport component 430 can be increased, thereby enabling the transport of items at deeper locations within the storage rack 900. Consequently, more layers of items arranged along the first horizontal direction YY can be provided in one or more rows of the storage rack 900. This increases the storage capacity of the warehouse.

[0073] In another embodiment of the present invention, the auxiliary transfer component 400 includes a suction mechanism 490, which is capable of adsorbing or releasing items. While adsorbing items, the suction mechanism 490 can also move the items along a first horizontal direction YY, thereby moving the items from the storage shelf 900 to the task module 300, or vice versa.

[0074] For example, such as Figure 9 As shown, the suction mechanism 490 includes a main frame 495, a suction arm 491, a suction body 492, and a suction cup 493. The main frame 495 can be connected to at least one longitudinal beam 100, thereby being movable along at least one longitudinal beam 100. The suction arm 491 is movably mounted on the main frame 495 along a first horizontal direction YY. The suction arm 491 is provided at the lower end of the suction arm 491, and at least one suction cup 493 is provided on the suction body 492. A suction generator 494 is provided on the suction arm 491, and the suction generator 494 is connected to at least one suction cup 493 through a pipeline air passage. After the suction generator 494 is activated, it can generate a vacuum suction force, enabling the suction cup 493 to adsorb items.

[0075] When an item needs to be transferred between the task module 300 and the storage rack 900, the main frame 495 moves along the longitudinal beam 100 above the task module 300, corresponding to the side of the item to be transferred. Then, the suction arm 491 moves along the first horizontal direction YY, causing the suction body 492 and suction cup 493 to approach the side of the item. After the suction cup 493 contacts the side of the item, the vacuum suction generated by the suction generator 494 causes the item to adhere to the suction cup 493. Then, the suction arm 491 moves along the first horizontal direction YY, using the suction cup 493 to move the item, transferring it from the storage rack 900 to the task module 300, or vice versa. Finally, the suction generator 494 removes the vacuum suction applied to the suction cup 493, causing the suction cup 493 to separate from the item.
