DETAILED DESCRIPTION

[0039] In the following description, some details of the present application are provided in order to better understand the technical scheme of the present application. However, it can be understood by those skilled in the art that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0040] According to one aspect of the present application, a transmission device is provided. The transmission device can take out an article on a storage operation position of a storage rack and carry it to a target position, or put the article into a target storage operation position of the storage rack. The transmission device can be applied to any suitable device, including but not limited to a storage system. Therefore, according to another aspect of the present application, a storage system is also provided. The transmission device and the storage system of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] In a storage environment, in order to improve efficiency, a cargo carrying system is currently provided on the market, such as Figure 1As shown in the figure, the goods handling system can include a plurality of lateral beams 10 extending along the X direction, a plurality of longitudinal beams 20 extending along the Z direction (i.e. the height direction of the storage rack), a support frame 30 and an access robot 40. The plurality of lateral beams 10 are installed on the side of the storage rack and arranged along the Z direction. The plurality of longitudinal beams 20 are movable along the plurality of lateral beams 10. The support frame 30 is installed on the plurality of longitudinal beams 20 and movable up and down along the longitudinal beams 20. The access robot 40 is installed on the support frame 30. Thus, the support frame 30 can drive the access robot 40 to move in the X-Y plane to reach any storage operation position of the storage rack. The access robot 40 can move along the Y direction to pull the goods on the storage rack to the support frame 30 or push the goods on the support frame 30 to the storage rack. Then, the support frame 30 can move in the X-Y plane to transfer the goods to a handling trolley or a manual transfer station.

[0042] During the process that the access robot 40 pulls the goods to the support frame 30, the access robot 40 will move along the Y direction together with the goods away from the storage rack, thus the access robot 40 will occupy the space on the support frame 30 in the Y direction. Moreover, the active arm 41 of the access robot 40 usually extends forwardly and flexibly towards the storage rack so that the pulling hook 42 at the front end of the active arm 41 can extend into the storage rack to hook the goods, thus the access robot 40 as a whole will occupy a larger space on the support frame 30 in the Y direction, resulting in a larger Y direction size of the support frame 30. In actual warehouse, a plurality of rows of storage racks are usually arranged at intervals along the Y direction, and the goods handling system is arranged in the aisle between the adjacent storage racks. The larger Y direction size of the support frame 30 means that the distance between the adjacent storage racks needs to be increased, resulting in a lower storage rate of the warehouse.

[0043] In order to reduce the space occupied by the access robot 40, an additional rotary motor can be arranged to drive the access robot 40 to rotate 90 degrees in the horizontal plane. After rotation, the pulling hook 42 faces the X direction, thus the space occupied by the access robot 40 in the Y direction can be reduced. However, a transmission belt 31 needs to be arranged on the support frame 30. After the access robot 40 pulls the goods to the limit position and rotates 90 degrees, there will be a gap between the goods and the base 43 of the access robot 40. The transmission belt 31 can continue to drive the goods to move so that the goods abut against the base 43 of the access robot 40. In order to avoid the access robot 40, the transmission belt 31 is arranged in two, respectively on the two sides of the access robot 40, thus a transmission motor 32 needs to be arranged for each transmission belt 31. The above scheme can improve the storage rate of the warehouse, but the structures of the support frame 30 and the access robot 40 become complex.

[0044] In the present application, as Figures 2 to 4 and Figure 10As shown, the transport apparatus 800 can include at least one longitudinal beam 100. The longitudinal beam 100 can be one, two, or more, for example. Each longitudinal beam 100 can extend along a longitudinal direction Z-Z. In embodiments where there are multiple longitudinal beams 100, the multiple longitudinal beams 100 can be arranged along a second horizontal direction X-X. The second horizontal direction X-X can be perpendicular to the longitudinal direction Z-Z. The longitudinal beam 100 can be made of any suitable material, such as aluminum or steel.

[0045] By way of example, the transport apparatus 800 can also include at least one lateral beam 700. The lateral beam 700 can extend along the second horizontal direction X-X. The at least one longitudinal beam 100 can be movable along the lateral beam 700. In embodiments where there are multiple lateral beams 700, the multiple lateral beams 700 can be arranged along the longitudinal direction Z-Z. The at least one longitudinal beam 100 can be movable along each lateral beam 700. The lateral beam 700 can be made of any suitable material, such as aluminum or steel.

[0046] The transport device 800 can further comprise a task module 300 and an auxiliary transport assembly 400. The task module 300 and the auxiliary transport assembly 400 can be connected to the at least one longitudinal beam 100. Exemplarily, the task module 300 and the auxiliary transport assembly 400 can move along the at least one longitudinal beam 100. In embodiments in which the transport device 800 comprises a transverse beam 700, the task module 300 and the auxiliary transport assembly 400 can move to any position within a plane defined by the second horizontal direction X-X and the longitudinal direction Z-Z, so as to be able to handle more items on the storage operation sites 901 of the storage racks 900. Specifically, the auxiliary transport assembly 400 can be configured to cooperate with the task module 300 of the transport system to access items at the storage operation sites 901 of the storage racks 900. The items can comprise goods and / or containers. The containers can comprise one or more of totes, which are adapted in size to the storage operation sites 901 of the storage racks 900, and original packages of the goods, etc. The totes can comprise plastic boxes or paper boxes, etc. The original packages can comprise one or more of original package boxes and original package bags, etc. When the goods are stored by means of totes, usually only one or a few sizes of totes are placed on each storage rack 900. When a container of goods needs to be picked, the auxiliary transport assembly 400 can move the container from the storage operation site 901 of the storage rack 900 to the task module 300. The target goods can then be picked from the container on the task module 300 manually or by means of a picking device, and subsequently be handled to a target location. Alternatively, the container on the task module 300 can be handled to the target location together with the goods therein by means of movement of the task module 300 along the longitudinal beam 100, and / or movement of the longitudinal beam 100 relative to the transverse beam 700. Alternatively, an empty container on the storage operation site 901 of the storage rack 900 can be moved to the task module 300 for the goods to be placed in the empty container. Alternatively, in cases where the goods are directly placed on the storage operation site 901 of the storage rack 900, the goods on the storage operation site 901 can be moved to the task module 300 as a whole, and then be handled to a target location by the task module 300 as a whole. Furthermore, in cases where only the goods are taken away without the container, the container can be only partially moved to the task module 300, as long as the goods therein can be picked out. In cases where the task module 300 needs to move the goods or the container to a target location as a whole, the goods or the container can be moved to the task module 300 completely, so as to avoid interference with the longitudinal beam 100 and / or the transverse beam 700 when the task module 300 moves along them. In summary, whether the empty containers, the containers filled with goods, or the goods are moved to the task module 300, or are moved from the task module 300 to the storage operation sites 901 of the storage racks 900, the working principle of the auxiliary transport assembly 400 is similar.

[0047] The storage rack 900 can have an access operation face 902 facing the transport device 800. The access operation face 902 can be parallel to the plane determined by the longitudinal beams 100 and the transverse beams 700 (i.e. the plane determined by the second horizontal direction X-X and the longitudinal direction Z-Z). The auxiliary transport assembly 400 can perform an access action, i.e. to take out an article or to store an article, at the storage operation site 901 via the access operation face 902.

[0048] At least one of the two sides opposite to each other along the second horizontal direction X-X of the task module 300 and the auxiliary transport assembly 400 can be connected to the longitudinal beam 100. Exemplarily, in the case of including one longitudinal beam 100, one of the two sides opposite to each other along the second horizontal direction X-X of the task module 300 and the auxiliary transport assembly 400 can be connected to the longitudinal beam 100. Exemplarily, in the case of including a plurality of longitudinal beams 100, the plurality of longitudinal beams 100 can be distributed at the two sides opposite to each other along the second horizontal direction X-X of the task module 300 and the auxiliary transport assembly 400. The two sides opposite to each other along the second horizontal direction X-X of the task module 300 and the auxiliary transport assembly 400 can be respectively connected to the longitudinal beams 100. Of course, in the case of including a plurality of longitudinal beams 100, the plurality of longitudinal beams 100 can also be arranged at one side of the task module 300 and the auxiliary transport assembly 400. The manner for driving the task module 300 and the auxiliary transport assembly 400 to move along the at least one longitudinal beam 100 can be arbitrary, for example, can be a manual manner, a motor-driven manner or a pneumatic cylinder-driven manner.

[0049] The task module 300 can include a space for placing an item. The auxiliary transport assembly 400 can be located above the space for placing an item. The auxiliary transport assembly 400 can be used to transport an item between the space for placing an item and the storage operation site 901 on the storage rack 900. The task module 300 can be capable of holding an item. The task module 300 can also be capable of holding an item by clamping or the like. The task module 300 can be a holding assembly, an automated guided vehicle (AGV), or an access robot. Exemplarily, the task module 300 can include a holding assembly. The holding assembly can include a holding site 301. The holding site 301 can be used to hold an item. The auxiliary transport assembly 400 can be used to transport an item between the holding site 301 of the holding assembly and the storage operation site 901 on the storage rack 900. The holding site 301 can be located at any suitable position of the holding assembly. Exemplarily, a top surface of the holding assembly can be configured to hold an item, i.e., the holding site 301 can include a space above the top surface of the holding assembly; or, the holding assembly can be configured to have a warehouse for placing an item, and the holding site 301 can include a space inside the warehouse. Exemplarily, the holding assembly can include a top wall, a bottom wall, and side walls, which are connected to each other to form a channel-like warehouse. An entrance and an exit of the channel can be directed towards the storage rack 900, so that an item can be moved between the storage operation site 901 on the storage rack 900 and the holding site 301.

[0050] The auxiliary transport assembly 400 can be spaced apart from the task module 300. For example, the auxiliary transport assembly 400 and the task module 300 can be completely spaced apart without any connecting member therebetween. In this embodiment, the auxiliary transport assembly 400 and the task module 300 can be connected to the at least one longitudinal beam 100 respectively. For example, a connecting member such as a bracket or a column can be connected between the spaced apart auxiliary transport assembly 400 and the task module 300 to space them apart by the connecting member. In this embodiment, one of the auxiliary transport assembly 400 and the task module 300 can be connected to the longitudinal beam 100. In the longitudinal direction Z-Z, the auxiliary transport assembly 400 can be located above the task module 300. In this way, the auxiliary transport assembly 400 can no longer interfere with the task module 300. Although in the illustrated embodiment, the auxiliary transport assembly 400 is located directly above the task module 300, in other embodiments not shown, the auxiliary transport assembly 400 can be located obliquely above the task module 300 as long as the auxiliary transport assembly 400 is located above the task module 300. The auxiliary transport assembly 400 can be used to transport items between the task module 300 and the storage operation site 901 on the storage rack 900. The auxiliary transport assembly 400 can engage with the items by any suitable means, such as by suction cups, clamps, hooks, magnets, etc., to achieve the purpose of transporting the items. Accordingly, the items can have an adaptive structure that is adapted to the auxiliary transport assembly 400. For example, in the case where the auxiliary transport assembly 400 engages the items by hooks, the items can be provided with an adaptive structure such as a handle or a groove for engaging with the hooks of the auxiliary transport assembly 400, and the auxiliary transport assembly 400 can engage with the adaptive structure to transport the items.

[0051] The storage system can include the storage rack 900 in addition to any of the transport devices 800 of the present application. The storage rack 900 can include a plurality of storage operation sites 901. Each storage operation site 901 can place an item. The storage rack 900 can have a first side and a second side opposite in a first horizontal direction Y-Y. The first horizontal direction Y-Y can be perpendicular to the second horizontal direction X-X and the longitudinal direction Z-Z. Therefore, the first horizontal direction Y-Y can be perpendicular to the access operation surface 902 of the storage rack 900. At least one of the first side and the second side can be provided with the transport device 800. Among them, the storage system can not only be applied to the warehouse to play the role of transferring items, but also can be applied to other scenes. For example, the storage system can be arranged on a production line, and the storage rack 900 can be located beside the production line, which can be used to store items required for production or store items produced. In this way, the storage system can serve as part of the production line to play the role of feeding or discharging items. In summary, the storage system can be applied to various scenes that require the transportation of items.

[0052] In summary, the transmission device 800 provided by this embodiment of the present invention, in addition to meeting the needs of handling items, also has the following advantages: First, the separately arranged task module 300 and auxiliary transmission component 400 no longer interfere with each other, thereby simplifying their structure and allowing for optimized design according to usage requirements. Based on this, the auxiliary transmission component 400 does not need to be located on the rear side of the task module 300 along the first horizontal direction YY (i.e., the side facing away from the storage rack 900), but can be spaced apart from the task module 300. Thus, the auxiliary transmission component 400 does not need to occupy space on the task module 300, reducing the restrictions on items on the task module 300. Therefore, the transmission device 800 can handle items of various specifications, especially non-standard items. In particular, since the auxiliary transmission component 400 no longer occupies space on the task module 300 along the first horizontal direction YY, the size of the task module 300 along the first horizontal direction YY can be reduced. Therefore, the spacing between adjacent storage racks 900 can be set smaller, thereby improving warehouse storage efficiency. Furthermore, the movement of items along the first horizontal direction YY is no longer restricted, allowing items to enter and exit the task module 300 unimpeded from both the front (facing the storage rack 900) and rear (facing away from the storage rack 900) sides, facilitating subsequent work. For example... Figure 11 As shown, the conveying device 800 can be positioned between two adjacent rows of storage racks 900 along the first horizontal direction YY. When items can enter and exit the task module 300 unobstructed from both sides, the auxiliary conveying component 400 can be configured to move items between the storage operation positions 901 on the two adjacent rows of storage racks 900 and the task module 300. For example, the auxiliary conveying component 400 can remove items from the rear of the task module 300 and move them to the storage operation position 901 on the storage rack 900 behind the task module 300; or, the picking device can remove items from the rear of the task module 300 and transfer them to a handling trolley or manual transfer station. This not only reduces the number of conveying devices 800 used in the warehouse but also makes the functions of the conveying devices 800 more rational, thereby improving work efficiency.

[0053] For example, such as Figure 11As shown, the storage rack 900 can include a first storage rack 910 and a second storage rack 920. The storage operation site 901 can include a first storage operation site 911 on the first storage rack 910 and a second storage operation site 921 on the second storage rack 920. The first storage rack 910 and the second storage rack 920 can be spaced apart along a first horizontal direction Y-Y to form a lane 930. The transport device 800 can be located within the lane 930. With the rapid development of the logistics industry, the density of the storage rack 900 is getting higher and higher, and thus the space of the lane 930 is more limited. The miniaturized transport device 800 can move within the narrower lane 930, so as to adapt to the development needs of the modern logistics industry. The auxiliary transport assembly 400 can be used to cooperate with the task module 300 to take and place the articles at the first storage operation site 911, and to cooperate with the task module 300 to take and place the articles at the second storage operation site 921. Specifically, the auxiliary transport assembly 400 can be used to carry the articles between the task module 300 and the first storage operation site 911, and to carry the articles between the task module 300 and the second storage operation site 921. In this way, the auxiliary transport assembly 400 can carry the articles directly between the two storage racks 900, so as to avoid the need to set a docking device between the two storage racks 900.

[0054] Exemplarily, as Figures 2 to 4As shown, the task module 300 and the auxiliary transport assembly 400 can be separated from each other and can be connected to the longitudinal beam 100 respectively. The task module 300 and the auxiliary transport assembly 400 can be movably connected to the longitudinal beam 100 at least on one side of the two opposite sides along the second horizontal direction X-X. The task module 300 and the auxiliary transport assembly 400 can be moved synchronously along the longitudinal beam 100 to ensure that the distance between them is constant. Exemplarily, the task module 300 and the auxiliary transport assembly 400 can be independently moved along the longitudinal beam 100 respectively, so that the distance between them along the longitudinal direction Z-Z is adjustable. For the embodiment in which the auxiliary transport assembly 400 and the task module 300 are separated from each other, when one of the task module 300 and the auxiliary transport assembly 400 moves, the other one is not affected, so that the distance can be adjusted. Moreover, the task module 300 can be completely free of restrictions, and the conveying device 800 can carry more types of articles. For the embodiment in which the auxiliary transport assembly 400 and the task module 300 are connected by a connecting member, one of the task module 300 and the auxiliary transport assembly 400 can be moved along the longitudinal beam 100, and the connecting member can include a telescopic support rod or a scissor support or any other suitable structure to ensure that the distance between the task module 300 and the auxiliary transport assembly 400 along the longitudinal direction Z-Z is adjustable. Exemplarily, the connecting member can include a lifting mechanism 810. The lifting mechanism 810 can be connected between the task module 300 and the auxiliary transport assembly 400 to adjust the movement of one of the task module 300 and the auxiliary transport assembly 400 along the longitudinal beam 100, so that the distance can be changed. The lifting mechanism 810 includes but is not limited to a motor mechanism or a pneumatic cylinder mechanism. Exemplarily, as shown in FIG. 8, the lifting mechanism 810 can include a motor 811, a screw rod 812 and a nut 813. The motor 811 can be arranged on the task module 300. The output shaft of the motor 811 can be connected to the screw rod 812 to drive the screw rod 812 to rotate. The nut 813 can be threadedly connected to the screw rod 812 and fixed to the auxiliary transport assembly 400. In this way, when the screw rod 812 rotates, the nut 813 can drive the auxiliary transport assembly 400 to move along the longitudinal beam 100. Figure 9

[0055] In actual application, the task module 300 usually needs to be moved to a position substantially flush with the storage operation site 901 of the storage rack 900, and then the auxiliary transport assembly 400 is engaged with the adaptive structure of the article to carry the article. Referring to Figure 1 ​For the existing access robot 40 arranged on the support frame 30, the spacing cannot be adjusted relative to the support frame 30, which results in that the access robot 40 can only engage to the fitting structure of the same height. For the article, the height of the fitting structure is fixed, so the existing access robot 40 can only carry the article with the fitting structure of the same height, and thus the applicability is poor. The auxiliary transmission assembly 400 of the present application is arranged apart from the task module 300, and the auxiliary transmission assembly 400 has the basis of adjusting the spacing with the task module 300. By adjusting the spacing of the task module 300 and the auxiliary transmission assembly 400 along the longitudinal direction Z-Z, when the task module 300 moves to the position substantially flush with the storage operation site 901 of the storage rack 900, the auxiliary transmission assembly 400 can engage the fitting structure of different heights. Therefore, the auxiliary transmission assembly 400 can carry articles of different specifications, and the applicability of the transmission device 800 is further enhanced.

[0056] Exemplarily, as shown in Figures 2 to 7 The transmission device 800 can further include a first driving assembly 500 and a second driving assembly 600. The first driving assembly 500 can be arranged on at least one of the at least one longitudinal beam 100. That is, the first driving assembly 500 can be arranged on only one longitudinal beam 100, or the first driving assembly 500 can be arranged on each of the plurality of longitudinal beams 100. The second driving assembly 600 can be arranged on at least one of the at least one longitudinal beam 100. That is, the second driving assembly 600 can be arranged on only one longitudinal beam 100, or the second driving assembly 600 can be arranged on each of the plurality of longitudinal beams 100.

[0057] Specifically, the first driving assembly 500 can include a first driver 510 and a first flexible transmission mechanism. The first flexible transmission mechanism can be connected between a driving end of the first driver 510 and one of the task module 300 and the auxiliary transport assembly 400. Under the driving of the first driver 510, the one of the task module 300 and the auxiliary transport assembly 400 can move along the at least one longitudinal beam 100. The first flexible transmission mechanism includes, but is not limited to, a belt transmission mechanism or a chain transmission mechanism. Specifically, the first flexible transmission mechanism can include a first wheel 520 and a first annular flexible member 530. The first driver 510 can be disposed on the longitudinal beam 100. The first wheel 520 can include a plurality of. The first annular flexible member 530 can be tensioned on the plurality of first wheels 520. The first annular flexible member 530 can include a first longitudinal segment 531 extending along the longitudinal direction Z-Z. The one of the task module 300 and the auxiliary transport assembly 400 can be connected to the first longitudinal segment 531. The driving 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, so that the first annular flexible member 530 can be driven to rotate, and in turn, the one of the task module 300 and the auxiliary transport assembly 400 connected thereto can be driven to move along the longitudinal direction Z-Z. The first driver 510 can adopt various types of drivers known in the art or possibly appearing in the future, including but not limited to a motor or a rotary air cylinder. The first wheel 520 and the first annular flexible member 530 can be adapted, for example, the first wheel 520 can include a belt wheel, and the first annular flexible member 530 can include a belt; or, the first wheel 520 can include a sprocket, and the first annular flexible member 530 can include a chain.

[0058] Similarly, the second driving assembly 600 can include a second driver 610 and a second flexible transmission mechanism. The second flexible transmission mechanism can be connected between a driving end of the second driver 610 and the other one of the task module 300 and the auxiliary transport assembly 400. Under the driving of the second driver 610, the other one of the task module 300 and the auxiliary transport assembly 400 can move along the at least one longitudinal beam 100. The second flexible transmission mechanism includes, but is not limited to, a belt transmission mechanism or a chain transmission mechanism. Specifically, the second flexible transmission mechanism can include a second wheel 620 and a second annular flexible member 630. The second driver 610 can be arranged on the longitudinal beam 100. The second wheel 620 can include a plurality of. The second annular flexible member 630 can be tensioned on the plurality of second wheels 620. The second annular flexible member 630 can include a second longitudinal section 631 extending along the longitudinal direction Z-Z. The other one of the task module 300 and the auxiliary transport assembly 400 can be connected to the second longitudinal section 631. The driving end of the second driver 610 can be connected to at least one of the plurality of second wheels 620 to drive the second wheel 620 to rotate, so as to drive the second annular flexible member 630 to rotate, and further drive the other one of the task module 300 and the auxiliary transport assembly 400 connected thereto to move along the longitudinal direction Z-Z. The second driver 610 can adopt various types of drivers known in the art or possibly appearing in the future, including but not limited to a motor or a rotary air cylinder. The second wheel 620 and the second annular flexible member 630 can be adapted, for example, the second wheel 620 can include a belt wheel, and the second annular flexible member 630 can include a belt; or, the second wheel 620 can include a sprocket, and the second annular flexible member 630 can include a chain. The first driving assembly 500 and the second driving assembly 600 thus arranged have a relatively low cost and are convenient to install and maintain in the later period. Especially for modern warehouse shelves 900, the height is getting higher and higher, so the task module 300 and the auxiliary transport assembly 400 need to move a longer path. In this case, the first driving assembly 500 and the second driving assembly 600 of the present embodiment have a relatively low cost.

[0059] By configuring the first drive component 500 and the second drive component 600, the task module 300 and the auxiliary transfer component 400 can move independently of each other 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. 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.

[0060] For example, such as Figure 7 As shown, the first annular flexible member 530 can surround the second annular flexible member 630. With this arrangement, the structures of the first drive assembly 500 and the second drive assembly 600 are more compact, thereby improving the space utilization of the transmission device 800 and facilitating miniaturization.

[0061] For example, such as Figures 2 to 7 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.

[0062] For example, such asFigures 2 to 7 As shown, the plurality of second wheels 620 can include a second upper end wheel 621 and a second lower end wheel 622. The second upper end wheel 621 and the second lower end wheel 622 can be disposed spaced apart along the longitudinal direction Z-Z. The second upper end wheel 621 can be located at the upper end of the longitudinal beam 100 where it is located. The second lower end wheel 622 can be located at the lower end of the longitudinal beam 100 where it is located. The upper end and the lower end of the second annular flexible member 630 can be sleeved on the second upper end wheel 621 and the second lower end wheel 622, respectively.

[0063] The first upper end wheel 521 can be located above the second upper end wheel 621. The number of the first upper end wheel 521 can be greater than the number of the second upper end wheel 621, for example, the first upper end wheel 521 can include two, and the second upper end wheel 621 can include one. Wherein: the diameter of the first upper end wheel 521 is not greater than the diameter of the second upper end wheel 621. In this way, a larger number of first upper end wheels 521 can protrude to both sides of the second upper end wheel 621 along the horizontal axial direction of the second upper end wheel 621, so as to make the first annular flexible member 530 located outside the second annular flexible member 630 at the upper end. Compared with using one large size first upper end wheel, a plurality of small size first upper end wheels 521 can reduce the weight and size, so as to make the transmission device 800 lightweight and small.

[0064] The first lower end wheel 522 can be located below the second lower end wheel 622. The number of the first lower end wheel 522 can be greater than the number of the second lower end wheel 622, for example, the first lower end wheel 522 can include two, and the second lower end wheel 622 can include one. Wherein: the diameter of the first lower end wheel 522 is not greater than the diameter of the second lower end wheel 622. In this way, a larger number of first lower end wheels 522 can protrude to both sides of the second lower end wheel 622 along the horizontal axial direction of the second lower end wheel 622, so as to make the first annular flexible member 530 located outside the second annular flexible member 630 at the lower end. Compared with using one large size first lower end wheel, a plurality of small size first lower end wheels 522 can reduce the weight and size, so as to make the transmission device 800 lightweight and small. In summary, the first annular flexible member 530 can surround the second annular flexible member 630.

[0065] Exemplarily, the driving end of the first driver 510 can be connected to one first upper end wheel 521, which can serve as a driving wheel, and the other first upper end wheels 521 and the first lower end wheels 522 can all serve as driven wheels. The driving end of the second driver 610 can be connected to one second upper end wheel 621, which can serve as a driving wheel, and the other second upper end wheels 621 and the second lower end wheels 622 can all serve as driven wheels.

[0066] Exemplarily, as shown in FIG. 6, the first annular flexible member 530 can be sleeved on the second annular flexible member 630. Figures 2 to 7As shown, the first driving assembly 500 and the second driving assembly 600 can be arranged on the same longitudinal beam 100. In the illustrated embodiment, there are two longitudinal beams 100, and each of the longitudinal beams 100 is arranged with the first driving assembly 500 and the second driving assembly 600. In other embodiments not shown, more or less longitudinal beams 100 can be arranged. Arranging the first driving assembly 500 and the second driving assembly 600 on the longitudinal beam 100 can reduce the number of longitudinal beams 100, and reduce the weight, size and manufacturing cost of the transport device 800. Especially for the embodiment in which the first annular flexible member 530 surrounds the second annular flexible member 630, it is more advantageous to be arranged on the same longitudinal beam 100 due to its small occupied space. The longitudinal beam 100 can be arranged with a transmission channel 110. The transmission channel 110 can extend through the longitudinal beam 100 along the longitudinal direction Z-Z. A portion of each of the first annular flexible member 530 and the second annular flexible member 630 can be arranged in the transmission channel 110. The first longitudinal section 531 and the second longitudinal section 631 can be located outside the transmission channel 110, so as to be connected to the task module 300 and the auxiliary transport assembly 400. Exemplarily, the first annular flexible member 530 can further include a third longitudinal section 532 extending along the longitudinal direction Z-Z. The third longitudinal section 532 can be arranged in parallel and opposite to the first longitudinal section 531. The first longitudinal section 531 can be located on a side of the first annular flexible member 530 facing the task module 300 and the auxiliary transport assembly 400, and the third longitudinal section 532 can be located on a side of the first annular flexible member 530 facing away from the task module 300 and the auxiliary transport assembly 400. The third longitudinal section 532 can be arranged in the transmission channel 110. The second annular flexible member 630 can further include a fourth longitudinal section 632 extending along the longitudinal direction Z-Z. The fourth longitudinal section 632 can be arranged in parallel and opposite to the second longitudinal section 631. The second longitudinal section 631 can be located on a side of the second annular flexible member 630 facing the task module 300 and the auxiliary transport assembly 400, and the fourth longitudinal section 632 can be located on a side of the second annular flexible member 630 facing away from the task module 300 and the auxiliary transport assembly 400. The fourth longitudinal section 632 can be arranged in the transmission channel 110.

[0067] Exemplarily, as Figure 8As shown, the first drive assembly 500 and the second drive assembly 600 can be mounted on different longitudinal beams 100. For example, two longitudinal beams 100 can be mounted on each side of the task module 300 and the auxiliary transmission assembly 400, and the two longitudinal beams 100 can include two arranged along a second horizontal direction XX. Optionally, the two longitudinal beams 100 can be attached to each other and connected. Optionally, a gap can also be provided between the two longitudinal beams 100. The first drive assembly 500 and the second drive assembly 600 can be mounted on the two longitudinal beams 100 respectively. With this configuration, the structure of the transmission device 800 is relatively simple, facilitating installation and subsequent maintenance.

[0068] For example, such as Figures 2 to 4 As shown, at least one side of the opposite sides of the task module 300 and the auxiliary transmission component 400 along the second horizontal direction XX can be connected to at least one longitudinal beam 100. Exemplarily, the opposite sides of the task module 300 and the auxiliary transmission component 400 along the second horizontal direction XX can each be connected to the longitudinal beam 100. Thus, the longitudinal beam 100 provides better guidance for the task module 300 and the auxiliary transmission component 400, and the stability of their movement is improved, thereby enhancing the safety of handling items. Each side of the opposite sides of the task module 300 and the auxiliary transmission component 400 along the second horizontal direction XX can be provided with a first drive component 500 and a second drive component 600. Therefore, when the first drive assembly 500 and the second drive assembly 600 are arranged on the same longitudinal beam 100, it means that within the same side, the first drive assembly 500 and the second drive assembly 600 are arranged on the same longitudinal beam 100 on the same side; when the first drive assembly 500 and the second drive assembly 600 are arranged on different longitudinal beams 100, it means that within the same side, the first drive assembly 500 and the second drive assembly 600 are arranged on different longitudinal beams 100 on the same side.

[0069] For example, such as Figures 2 to 4As shown, the auxiliary transport assembly 400 can include a transport body 410, a transport driving mechanism and a transport member 430. The transport body 410 can be connected to the at least one longitudinal beam 100 so as to be movable along the at least one longitudinal beam 100. For example, both ends of the transport body 410 can be movably connected to the longitudinal beam 100 along the second horizontal direction X-X. The transport body 410 can include any suitable structure such as a bracket, a base or the like. The transport driving mechanism can be arranged on the transport body 410. A driving end of the transport driving mechanism can be connected to the transport member 430 for driving the transport member 430 to transport the article between the task module 300 and the storage operation station 901. The transport member 430 can be configured to connect to the article. The transport driving mechanism can include a motor mechanism, a pneumatic cylinder mechanism and / or a hydraulic cylinder mechanism. In this way, the auxiliary transport assembly 400 has a simple structure and is easy to manufacture.

[0070] For example, the transport driving mechanism can include a movable arm subassembly, a movable arm driver and a transport driver 423. One end of the movable arm subassembly can be connected to the transport body 410, and the transport driver 423 can be mounted at the other end of the movable arm subassembly, and a driving end of the transport driver 423 can be connected to the transport member 430. The movable arm subassembly can be movable under the driving of the movable arm driver, and the transport member 430 can be movable under the driving of the transport driver 423. The movable arm subassembly can be folded and / or stretched and the like under the driving of the movable arm driver, so as to move the position of the transport member 430, so that the transport member 430 can engage with the article and transport the article.

[0071] For example, as shown, Figures 2 to 4 The movable arm driver can include a first movable arm driver 421 and a second movable arm driver 422. The movable arm subassembly can include a first movable arm 424 and a second movable arm 425.

[0072] One end of the first movable arm 424 can be rotatably connected to the carrying body 410. The driving end of the first movable arm driver 421 can be connected to the first movable arm 424 for driving the first movable arm 424 to rotate around a first axis parallel to the second horizontal direction X-X. Alternatively, one end of the first movable arm 424 can be directly connected to the driving end of the first movable arm driver 421 for being driven to rotate by the first movable arm driver 421. The second movable arm driver 422 can be arranged on the first movable arm 424. The driving end of the second movable arm driver 422 can be connected to the second movable arm 425 for driving the second movable arm 425 to rotate around a second axis parallel to the second horizontal direction X-X. Alternatively, the second movable arm 425 can be rotatably connected to the first movable arm 424 or directly connected to the driving end of the second movable arm driver 422. The carrying driver 423 can be arranged on the second movable arm 425. The driving end of the carrying driver 423 can be connected to the carrying member 430 for driving the carrying member 430 to rotate around a third axis parallel to the second horizontal direction X-X. Alternatively, the carrying member 430 can be rotatably connected to the second movable arm 425 or directly connected to the driving end of the carrying driver 423. In this way, the carrying member 430 has a very high degree of freedom in a plane perpendicular to the second horizontal direction X-X, so that it can be rotated to any desired position, thereby facilitating the connection of the adapter to the article for carrying the article. Moreover, the carrying driving mechanism can be configured to drive the carrying member 430 to extend to the outside of the task module 300 on both sides along the first horizontal direction Y-Y. In this way, the carrying driving mechanism can drive the carrying member 430 to access the first storage rack 910 and the second storage rack 920 to carry the articles on the first storage rack 910 and the second storage rack 920. The first movable arm driver 421, the second movable arm driver 422 and the carrying driver 423 can each include a motor or a rotary air cylinder or any other suitable driver.

[0073] In the illustrated embodiment, the movable arm subassembly includes two movable arms. In other embodiments not shown, the movable arm subassembly can include more or less movable arms. In the case of including only one movable arm, the length of the carrier 430 can be increased, thereby the movable range of the carrier 430 can be increased. In addition, in the illustrated embodiment, each movable arm in the movable arm subassembly and the rotation axis of the carrier 430 are parallel to the second horizontal direction X-X, but in other embodiments not shown, each movable arm and the rotation axis of the carrier 430 can extend in different directions. For example, in the embodiment where the auxiliary transport assembly 400 is disposed obliquely above the task module 300, the rotation axis of each movable arm and at least one of the carrier 430 can be substantially parallel to the first horizontal direction Y-Y, so as to be able to carry articles between the storage operation site 901 of the storage rack 900 and the task module 300. Even if the auxiliary transport assembly 400 is disposed directly above the task module 300, the rotation axis of each movable arm and at least one of the carrier 430 can not be parallel to the second horizontal direction X-X, as long as the carrying function is enabled.

[0074] Exemplarily, as shown in Figures 2 to 4 The carrier 430 can be provided with a carrying part 431 for carrying articles on both sides of its moving track. The carrying parts 431 can be oppositely arranged along the rotation direction of the carrier 430. The carrying parts 431 can be used to engage to the adaptation structure of the articles. In this way, the carrying part 431 on one side can carry articles between the first storage operation site 911 of the first storage rack 910 and the task module 300, and the carrying part 431 on the other side can carry articles between the second storage operation site 921 of the second storage rack 920 and the task module 300. The carrying part 431 includes but is not limited to a suction cup, a clamping jaw or a hook.

[0075] Exemplarily, as shown in Figures 2 to 4As shown, the carrying driving mechanism can include a translation driving sub-mechanism arranged on the carrying body 410. The movable arm sub-assembly is movable along the first horizontal direction Y-Y under the driving of the translation driving sub-mechanism. Exemplarily, the translation driving sub-mechanism can include a translation driver 426. The driving end of the translation driver 426 can be connected to the carrying member 430 for driving the carrying member 430 to move along the first horizontal direction Y-Y. In this way, the stroke of the carrying member 430 along the first horizontal direction Y-Y can be increased to carry the items at a deeper position of the storage rack 900. Moreover, the carrying member 430 can be moved between the first storage rack 910 and the second storage rack 920 to facilitate carrying the items on the first storage rack 910 and the second storage rack 920. In the embodiment in which the carrying driving mechanism includes the first movable arm driver 421, the driving 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 carrying driver 423, the first movable arm 424, the second movable arm 425 and the carrying member 430 to move synchronously along the first horizontal direction Y-Y. The translation driver 426 includes, but is not limited to, a motor or a pneumatic cylinder. Exemplarily, the carrying body 410 can be provided with a translation guide rail 411 extending along the first horizontal direction Y-Y. The driving end of the translation driver 426 can be connected to a pulley of a belt transmission mechanism 427 to drive the pulley to rotate. The belt of the belt transmission mechanism 427 can be provided with a sliding block 428. The translation driver 426 can drive the belt of the belt transmission mechanism 427 to rotate to drive the sliding block 428 to slide along the translation guide rail 411. The first movable arm driver 421 and / or the first movable arm 424 can be arranged on the sliding block 428. In this way, the movable arm sub-assembly, the movable arm driver and the like can move along the first horizontal direction Y-Y with the sliding block 428.

[0076] In the above embodiments, the carrying stroke of the carrying member 430 can be increased by arranging more movable arms and / or arranging the translation driving sub-mechanism, so that the items at a deeper position of the storage rack 900 can be carried. Thus, more layers of items arranged along the first horizontal direction Y-Y can be arranged for one row or multiple rows of the storage rack 900. In this way, the storage rate of the warehouse can be increased.

[0077] Exemplarily, as shown in FIG. 1, the movable arm sub-assembly can include a first movable arm 424 and a second movable arm 425. The first movable arm 424 and the second movable arm 425 can be arranged on the carrying member 430.

Figures 2 to 4As shown, task module 300 may include a support body 310. The support body 310 may be connected to at least one longitudinal beam 100, thereby being movable along at least one longitudinal beam 100. Exemplarily, both ends of the support body 310 may be movably connected to the longitudinal beam 100 along the second horizontal direction XX. The support body 310 includes, but is not limited to, any suitable structure such as a bracket or base. The support body 310 may include a conveying mechanism 311. The conveying mechanism 311 may be used to define a support position 301. The conveying mechanism 311 may move an item on the support position 301 along a first horizontal direction YY. The first horizontal direction YY is perpendicular to the second horizontal direction XX and the longitudinal direction ZZ, respectively. This configuration allows the conveying mechanism 311 to facilitate the conveying of an item along the first horizontal direction YY. Although in the illustrated embodiment, the conveying mechanism 311 includes a conveyor belt, in other embodiments not shown, the conveying mechanism 311 includes one or more of the following: a conveyor roller, a conveyor chain, etc.

[0078] For example, such as Figures 2 to 4 As shown, the supporting body 310 may have a supporting surface 312 defining the supporting position 301. The supporting surface 312 may be the top surface of the supporting body 310 or any other suitable surface. The supporting surface 312 may be configured to accommodate articles of various sizes along a second horizontal direction XX. For example, along a first horizontal direction YY, the supporting surface 312 may extend from one side of the supporting body 310 to the other. The width of the supporting surface 312 may be set to match the widest commonly used articles. In this way, regardless of the width of the article, it can be placed on the supporting surface 312. Figure 1 As shown, existing technologies use spaced-apart conveyor belts 31 on both sides of the access robot 40 to avoid obstructing its movement. This can prevent narrow-width items from being supported on the support body 310. In this application, the auxiliary transmission component 400 is positioned above the support position 301 of the task module 300, thus maintaining the integrity of the support surface 312 and allowing for the adaptation of narrow-width items. Optionally, the support surface 312 of this application can also include multiple sub-support surfaces spaced relatively close together along the second horizontal direction XX, as long as the spacing does not cause items to fall off the support body 310 or become stuck in the gaps between the sub-support surfaces.

[0079] For example, such as Figures 2 to 4 As shown, the support body 310 can be configured to allow items to enter and exit the support position 301 from both opposite sides along the first horizontal direction YY. In this way, the auxiliary transfer assembly 400 can facilitate the handling of items between the support position 301 and the first storage operation position 911 of the first storage rack 910, and between the support position 301 and the second storage operation position 921 of the second storage rack 920.
