Description

Technical Field

[0001] This utility model generally relates to the field of logistics and transportation technology, and more specifically, to a track component, a shelf structure, and a shelf robot automated storage and retrieval system. Background Technology

[0002] Wall-mounted rack robots are automated material handling devices used in high-density warehousing systems. They are suitable for manufacturing raw material warehouses or cold chain material centers where large quantities of standardized materials are stored. Typically, the racks have rail structures on their sides, allowing the wall-mounted rack robots to move along these rails, transporting goods and reducing manual handling time.

[0003] The existing track structure includes a track, mounting components, and clamping components. The mounting components are installed on the shelf, and the clamping components press the track onto the mounting components. There are two main types of tracks: one is an aluminum alloy profile track, which is directly extruded from a mold according to usage requirements; the other is a sheet metal track, which is bent from sheet metal. Because the track structure has three parts—track, mounting components, and clamping components—the number of parts is relatively large, resulting in high production costs. Furthermore, the numerous connection points between the track, mounting components, and clamping components make them prone to failure during long-term use, affecting the reliability and safety of the wall-mounted shelf robot.

[0085] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0086] This embodiment provides a robotic automated warehouse system, suitable for applications in manufacturing raw material warehouses, cold chain logistics centers, and medium-sized warehouse renovations. Figure 1 As shown, the automated storage and retrieval system (AS / RS) includes a rack robot 400 and a rack structure. The rack structure includes a rack 200 and a track assembly 100. The track assembly 100 is mounted on the rack 200, and the rack robot 400 can slide relative to the track assembly 100.

[0087] Since the shelf 200 has a certain length and height, the track assembly 100 can make full use of the height and length space of the shelf 200. The shelf 200 provides an installation position for the track assembly 100, ensuring the installation stability of the track assembly 100.

[0088] The shelf robot 400 is a wall-mounted structure. It can slide relative to the track assembly 100 via wireless remote control or an automated system. The track assembly 100 provides guidance for the shelf robot 400 and can plan the movement path of the shelf robot 400, ensuring the smooth movement of the shelf robot 400.

[0089] In this way, the shelf robot 400 can move freely relative to the shelf 200 via the track component 100. The shelf robot 400 can correspond to goods at any position on the shelf 200, realizing automatic storage and retrieval of goods. It has high operating efficiency and saves space, making it suitable for scenarios with high storage density.

[0090] The number of shelves 200 can be selected to be multiple, and multiple shelves 200 are arranged in parallel and spaced apart. The shelf robot 400 can be located between two adjacent shelves 200, that is, the shelf robot 400 is located in the middle aisle formed between two adjacent shelves 200.

[0091] The shelf 200 has a rectangular frame structure and at least one reference plane, which is parallel to the horizontal plane. The length and width directions of the shelf 200 are perpendicular to each other within the reference plane. The length direction of the shelf 200 can also be called the horizontal direction, denoted by D1. The width direction of the shelf 200 is denoted by D2. The height direction of the shelf 200 is perpendicular to the reference plane and can also be called the vertical direction, denoted by D3. The length, width, and height directions of the shelf 200 are mutually perpendicular. Because the shelf 200 is relatively long, the track assembly 100 extends along the length direction of the shelf 200; that is, the extension direction of the track assembly 100 is the length direction of the shelf 200.

[0092] like Figure 2 As shown, the shelf robot 400 includes a lifting track 401 and wheels 402. The wheels 402 are rotatably connected to the side of the lifting track 401 facing the track assembly 100. The lifting track 401 can move horizontally relative to the track assembly 100 through the rolling engagement of the wheels 402 and the track assembly 100. With this configuration, the lifting track 401 can be suspended on the track assembly 100, and the rolling friction between the wheels 402 and the track assembly 100 is relatively small, improving the smoothness of the lifting track 401's reciprocating movement along the length of the shelf 200 on the track assembly 100.

[0093] The track assembly 100 can correspond to one traveling wheel 402, which is a single-wheel structure; alternatively, the track assembly 100 can correspond to multiple traveling wheels 402, for example, Figures 2-3 As shown, two traveling wheels 402 are respectively set on both sides of the lifting track 401. The traveling wheel 402 is a single wheel structure to ensure the stability of the lifting track 401 in the length direction of the support 201.

[0094] The lifting rail 401 is equipped with a storage and retrieval platform (not shown in the figure), which is used for retrieving goods. The storage and retrieval platform can move vertically up and down relative to the lifting rail 401. With this configuration, the storage and retrieval platform can retrieve goods from the shelf 200 in both the height direction and the length direction of the shelf 200, thereby increasing the retrieval range.

[0095] like Figure 2 As shown, there are multiple track components 100, which are distributed along the height of the shelf 200. For example, there are three track components 100, located at the upper, middle, and lower parts of the shelf 200, respectively. The shelf robot 400 and the three track components 100 slide together, so that the weight of the shelf robot 400 is distributed on the three track components 100, improving the stability of the shelf robot 400's movement.

[0096] like Figures 2-3 As shown, there are multiple traveling wheels 402, which are respectively arranged on both sides of the lifting rail 401 along the extension direction of the track assembly 100. For example, there are six traveling wheels 402, which are divided into three groups of traveling wheels. The three groups of traveling wheels are arranged corresponding to the three track assemblies 100. Each group of traveling wheels has two traveling wheels 402, which are respectively arranged on both sides of the lifting rail 401 along the extension direction of the track assembly 100, thereby improving the balance of the lifting rail 401 in the length and height directions of the support 201.

[0097] The lifting track 401 includes two vertical rods and multiple horizontal rods. The two vertical rods are arranged in parallel and spaced apart, and the multiple horizontal rods are arranged between the two vertical rods. The vertical rods extend along the height direction of the support 201, and the horizontal rods extend along the length direction of the support 201, so that the lifting track 401 forms a frame structure.

[0098] In one embodiment, such as Figures 4-5 As shown, the track assembly 100 is provided with a guide part 24, and the lifting track 401 is provided with a guide mating part corresponding to the guide part 24. The guide part 24 and the guide mating part slide together for guiding the lifting track 401.

[0099] The sliding engagement between the guide section 24 and the guide mating section provides a guiding path for the movement of the lifting track 401, preventing the lifting track 401 from deviating during movement and ensuring the smooth movement of the lifting track 401.

[0100] like Figures 4-5As shown, the guide engagement part includes a mounting base 403 and a plurality of guide wheels 404. The mounting base 403 is disposed on the side of the lifting rail 401 facing the rail assembly 100. The plurality of guide wheels 404 are spaced apart and are rotatably connected to the mounting base 403. For example, two guide wheels 404 are rotatably connected to the mounting base 403 via two rotating shafts, and the two guide wheels 404 can rotate relative to the mounting base 403 via the two rotating shafts. The guide part 24 is inserted between two adjacent guide wheels 404 and rolls with them.

[0101] With this configuration, the guide part 24 is sandwiched between two adjacent guide wheels 404, and the two sides of the guide part 24 abut against the two adjacent guide wheels 404 respectively. One guide wheel 404 is used to guide the two guide wheels 404, thereby improving the smoothness of the operation of the shelf robot 400.

[0102] In one embodiment, the guide portion 24 may be a guide rail, and the guide mating portion may be a guide groove. For example, the rail 2 is provided with a guide rail on the side away from the support member 1. The guide rail extends along the extension direction of the rail assembly 100. The lifting rail 401 is provided with a guide groove corresponding to the guide rail. The guide rail passes through the guide groove to provide a guiding force for the lifting rail 401.

[0103] This embodiment also provides a track assembly 100, such as Figures 6-7 As shown, the track assembly 100 includes a track 2 and a support member 1. The track 2 is provided with a track surface 20, which is used for sliding engagement with the shelf robot 400. The support member 1 is detachably connected to the shelf 200 and is used to support the track 2. The track 2 is connected to the support member 1. One of the support member 1 and the track 2 is provided with a snap-fit ​​part 11, and the other is provided with a snap-fit ​​engagement part 21, with the snap-fit ​​part 11 snapping into the snap-fit ​​engagement part 21.

[0104] In one embodiment, the track 2 is made of aluminum profile, which has the advantage of being lightweight. The track 2 is a one-piece molded structure, or it can be formed by extrusion molding followed by cutting and machining holes. The track 2 is extruded by a mold to ensure the uniformity of the track 2's shape. Along the height direction of the support 201, the top surface of the track 2 has a track surface 20, along which the wheels 402 of the shelf robot 400 can roll.

[0105] Among them, the load-bearing component 1 is installed on the shelf 200 and has good fixation. The load-bearing component 1 can support the track 2. The load-bearing component 1 can also be called the track hanger. The load-bearing component 1 provides a certain support force for the track 2.

[0106] The engaging part 11 can be a engaging protrusion, and the engaging mating part 21 can be a engaging groove. For example, the carrier 1 has an engaging protrusion, and the track 2 has an engaging groove. The engaging protrusion engages with the engaging groove, achieving positioning between the carrier 1 and the track 2 while also providing a fixing effect. Along the height direction of the bracket 201, the engaging part 11 can be located on the top of the carrier 1. The engaging position between the engaging part 11 and the engaging mating part 21 is the hooking position between the track 2 and the carrier 1. Under the mutual cooperation of the engaging part 11 and the engaging mating part 21, the track 2 hooks onto the carrier 1.

[0107] The track assembly 100 provided in this embodiment, during installation, first installs the carrier 1 onto the shelf 200, and then places the track 2 onto the carrier 1. Compared with the prior art track which requires three components, the track assembly 100 only has two components: the carrier 1 and the track 2, omitting a clamping component, reducing the number of parts, and lowering raw material and assembly costs. The track 2 is detachably connected to the carrier 1, and the snap-fit ​​part 11 snaps into the snap-fit ​​mating part 21. At this time, there are two connection positions between the track 2 and the carrier 1, which has a double fixing effect, reducing the risk of failure during long-term use, improving the connection stability between the track 2 and the carrier 1, and thus ensuring the reliability and safety of the shelf robot 400's movement.

[0108] In one embodiment, such as Figures 6-7 As shown, the carrier 1 includes a mounting part 12 for mounting the shelf 200. The mounting part 12 and the shelf 200 can be connected by welding, bolting, snap-fitting, or other methods. A snap-fitting part 11 or a snap-fit ​​mating part 21 is provided on the side of the mounting part 12 facing the track surface 20. With this arrangement, the connection position between the mounting part 12 and the shelf 200 will not interfere with the traveling wheels 402, ensuring the smooth movement of the shelf robot 400.

[0109] The support component 1 also includes a support part 13, which protrudes from the mounting part 12 on the side facing the track 2 and is used to support the track 2. With this arrangement, the connection between the support part 13 and the track 2 will not interfere with the walking wheel 402, ensuring the smooth movement of the shelf robot 400.

[0110] In one embodiment, such as Figure 6As shown, the track 2 includes a track body 22 and a fixing part 23. A track surface 20 is disposed on the track body 22, and the fixing part 23 is disposed on the side of the track body 22 away from the track surface 20. Specifically, along the height direction of the shelf 200, the track surface 20 is located on the top surface of the track body 22, and the fixing part 23 protrudes from the bottom surface of the track body 22. The fixing part 23 is disposed on and detachably connected to the support part 13. The support part 13 provides a certain supporting force to the fixing part 23, allowing the track body 22 to be suspended.

[0111] Among them, such as Figure 6 As shown, the track body 22 has a contact surface 221 on the side facing the mounting part 12, and the mounting part 12 has a support surface 121 corresponding to the contact surface 221, with the support surface 121 fitting snugly against the contact surface 221. This arrangement provides a certain supporting force to the track body 22 using the support surface 121 of the mounting part 12, and the close fit between the support surface 121 and the contact surface 221 improves the fixing effect between the track 2 and the load-bearing member 1.

[0112] In one embodiment, such as Figures 6-7 As shown, the track assembly 100 also includes a connecting component 3, through which the track 2 is detachably connected to the carrier 1. This arrangement facilitates the installation and disassembly of the track 2 and carrier 1 when wear occurs after long-term use, reducing maintenance costs. Furthermore, the track 2 and carrier 1 have both snap-fit ​​and locking connection positions, providing good fixation.

[0113] like Figures 6-7 As shown, the connecting component 3 includes a connector 32, which can be optionally bolted. The track 2 is provided with a fixing groove 231, and the bearing component 1 is provided with a connecting hole 131 corresponding to the fixing groove 231. The connector 32 passes through the connecting hole 131 and the fixing groove 231 to achieve fixation between the bearing component 1 and the track 2. At least one of the inner walls of the connecting hole 131 and the fixing groove 231 is provided with an internal thread, and the connector 32 is threadedly connected to the internal thread.

[0114] The fixing groove 231 is located on the side of the fixing part 23 away from the track surface 20. The connecting member 32 passes through the connecting hole 131 and the fixing groove 231 of the bearing part 13, realizing the locking and fixing between the fixing part 23 and the bearing part 13, which facilitates the installation and disassembly of the track 2 and improves maintenance convenience. At the same time, the locking positions between the track surface 20 and the bearing member 1 and the track 2 are located on both sides of the track 2, avoiding interference between the connecting member 3 and the traveling wheel 402, and ensuring the reliability of the movement of the traveling wheel 402.

[0115] In one embodiment, the connecting component 3 further includes a locking member 31, which may be a T-nut or a square nut. The locking member 303 is disposed in the fixing groove 231 and abuts against the groove wall of the fixing groove 231. The track 2 is a profile. After the fixing groove 231 is opened on the track 2, the area of ​​the track 2 around the fixing groove 231 has a certain elasticity. After the locking member 303 is placed in the fixing groove 231, the inner wall of the fixing groove 231 can clamp the locking member 303, and the locking member 303 is fixed in position relative to the track 2. Then, the connecting member 32 is passed through the bearing member 1 and the locking member 31. The locking member 303 will not rotate with the rotation of the connecting member 32. Through the cooperation between the connecting member 32 and the locking member 303, the track 2 is locked on the bearing member 1.

[0116] The number of connectors 32, connecting holes 131, fixing grooves 231 and locking members 303 can be multiple. For example, two connectors 32 are respectively inserted into two connecting holes 131, two fixing grooves 231 and two locking members 303 to ensure the connection stability between the track 2 and the bearing member 1.

[0117] Along the height direction of the shelf 200, the track surface 20 at the top of the track body 22 provides a guiding surface for the traveling wheels 402. Along the height direction of the shelf 200, a locking point is formed between the fixing part 23 at the bottom of the track body 22 and the bearing part 13 of the bearing member 1. A guide part 24 is also provided at the bottom of the track body 22, which rolls in cooperation with the guide wheels 404 of the shelf robot 400. Along the width direction of the shelf 200 and facing one side of the shelf 200, the track body 22 is provided with a snap-fit ​​part 21 and a contact surface 221, forming a hook-and-position point between the snap-fit ​​part 11 and the snap-fit ​​part 21. Along the width direction of the shelf 200 and away from the shelf 200, the track body 22 is provided with a contact surface 221, which forms a stable supporting cooperation with the support surface 121 of the bearing member 1. With this configuration, different surfaces of the track 2 have different functions, resulting in reasonable functional zoning and strong functionality.

[0118] Along the height direction of the shelf 200, the top of the support member 1 has a snap-fit ​​part 11, and a hook-and-lock positioning point is formed between the snap-fit ​​part 11 and the snap-fit ​​mating part 21. Along the width direction of the shelf 200, the side of the support member 1 facing the shelf 200 provides an installation position for the shelf 200, and the side of the support member 1 away from the shelf 200 is provided with a support part 13, which provides a support position for the track body 22. With this arrangement, different surfaces of the support member 1 have different functions, the functional zoning is reasonable, and the functionality is relatively strong.

[0119] In one embodiment, such as Figure 6As shown, at least one of the support member 1 and the track 2 is provided with a weight-reducing part 10. The weight-reducing part 10 can be a weight-reducing groove or a weight-reducing hole. The weight-reducing groove can be a rectangular groove, a circular groove, etc., and the weight-reducing hole can be a circular hole or a rectangular hole, etc. Due to limitations such as structural strength and self-weight, one or more weight-reducing parts 10 can be provided on the support member 1 and the track 2. For example, the track body 22 of the track 2 is provided with a weight-reducing hole. The weight-reducing hole can be a rectangular through hole. There are two weight-reducing holes, which are arranged vertically along the height direction of the bracket 201, and the two weight-reducing holes have different sizes. The mounting part 12 of the support member 1 is provided with a weight-reducing groove on the side facing the bracket 201. The weight-reducing groove is a rectangular groove.

[0120] The number of rails 2 can be selected as one, with one rail 2 extending along the length of the bracket 201. This integral and continuous structure reduces the number of parts assembly steps and lowers the production cost. Alternatively, there can be multiple rails 2, which are arranged along the extension direction of the rail assembly 100. This segmented structure facilitates the installation and maintenance of the rails 2.

[0121] The track assembly 100 also includes positioning elements (not shown in the figure). The track 2 is provided with positioning holes 222, and the positioning elements pass through the positioning holes 222 of two adjacent tracks 2. In this way, when multiple tracks 2 need to be spliced, the positioning elements are passed through the positioning holes 222 of two adjacent tracks 2 to achieve positioning between the two adjacent tracks 2 and ensure the alignment accuracy between the two adjacent tracks 2.

[0122] The system includes multiple positioning holes 222 and positioning elements, with the positioning elements corresponding to multiple positioning holes 222. For example, there are two positioning holes 222, located on both sides of the weight reduction part 10 corresponding to the track 2, to ensure the balance of two adjacent tracks 2 when docking.

[0123] like Figures 8-9 As shown, the shelving structure provided in this embodiment includes a shelving unit 200 and a track assembly 100, with the track assembly 100 installed on the shelving unit 200. The shelving unit 200 includes a support frame 201 and shelf assemblies 202. The shelf assemblies 202 are disposed on the support frame 201 and perpendicular to the height direction of the support frame 201. The support frame 201 provides support to the shelf assemblies 202, which are used to support goods. Multiple shelf assemblies 202 can be selected, arranged along the height direction of the support frame 201 to fully utilize vertical space and increase storage density.

[0124] like Figure 10As shown, the shelf assembly 202 includes two crossbeams 2021 and multiple support members 2022. The two crossbeams 2021 are arranged in parallel and spaced apart. The crossbeams 2021 can be of square tube structure to meet the requirements of lightweight design. The multiple support members 2022 are arranged in parallel and spaced apart between the two crossbeams 2021. The crossbeams 2021 extend along the length direction of the shelf 200, and the support members 2022 extend along the width direction of the shelf 200, so that the shelf assembly 202 forms a frame structure.

[0125] In one embodiment, the shelf assembly 202 further includes hanging ears 2023, which are disposed at the ends of the crossbeams 2021. The hanging ears 2023 may be L-shaped, and the crossbeams 2021 are fixed to the bracket 201 via the hanging ears 2023. There are four hanging ears 2023, with two hanging ears 2023 at each end of one crossbeam 2021 and two hanging ears 2023 at each end of the other crossbeam 2021. That is, the shelf assembly 202 is fixed to the four columns of the bracket 201 via the four hanging ears 2023.

[0126] Among them, such as Figures 10-12 As shown, the track assembly 100 is disposed on at least one of the two crossbeams 2021 on opposite sides. The track assembly 100 may be located on one side of the shelf assembly 202, for example, the track assembly 100 may be fixed to the side wall of one of the crossbeams 2021; the track assembly 100 may also be located on both sides of the shelf assembly 202 to improve conveying efficiency.

[0127] In one embodiment, such as Figure 13 As shown, the track assembly 100 is detachably connected to the shelf 200 via the mounting assembly 300. The load-bearing component 1 is detachably connected to the crossbeam 2021 via the mounting assembly 300, facilitating the installation and maintenance of the track assembly 100 and reducing subsequent maintenance costs.

[0128] The number of mounting components 300 can be selected to be multiple. Multiple mounting components 300 are arranged along the length of the bracket 201, so that the shelf 200 and the track assembly 100 are connected by multiple mounting components 300, thereby improving installation stability.

[0129] like Figures 14-19 As shown, the installation component 300 includes a limiting member 301. The support member 1 of the track component 100 is provided with a limiting groove 122 on the side facing the shelf 200. The limiting member 301 passes through the shelf 200 and abuts against the limiting groove 122, and the limiting groove 122 plays a limiting role.

[0130] During installation, the limiting component 301 passes through the crossbeam 2021 from the side away from the track assembly 100 and abuts against the limiting groove 122 and cooperates with each other to form a sub-positioning, ensuring the uniqueness and accuracy of the position of the bearing component 1 of the track assembly 100, and making the position of the track 2 hanging on the bearing component 1 accurate, thereby improving the stability of the shelf robot 400 when it runs and walks.

[0131] Among them, such as Figures 18-20 As shown, a limiting boss 3011 is provided on the side of the limiting member 301 away from the carrier member 1. The limiting boss 3011 abuts against the shelf 200 and serves as a limiting element to prevent insufficient or excessive insertion when the limiting member 301 is inserted into the crossbeam 2021. With this configuration, the limiting groove 122 and the limiting boss 3011 work together to limit both ends of the limiting member 301. In addition, since the limiting boss 3011 is located on the side of the limiting member 301 away from the carrier member 1, when the carrier member 1 pulls the limiting member 301 with a large weight of the track 2, the limiting member 301 will not detach from the crossbeam 2021 along with the carrier member 1, ensuring the installation reliability of the track assembly 100.

[0132] In one embodiment, the limiting boss 3011 has a welding surface 3012 on the side facing the shelf 200, and the limiting boss 3011 is connected to the shelf 200 through the welding surface 3012. By welding the welding surface 3012 to the crossbeam 2021 of the shelf 200, the limiting member 301 is fixed to the crossbeam 2021, preventing the limiting member 301 from shifting position. Simultaneously, after the limiting member 301 passes through the crossbeam 2021, it is welded on the side that does not cooperate with the support member 1. The welding surface 3012 will not interfere with the support member 1 and the mounting assembly 300, reducing installation difficulty. The limiting boss 3011 can either abut against the crossbeam 2021 or be welded to the crossbeam 2021, which can be adjusted according to actual production conditions.

[0133] like Figure 18 As shown, the mounting assembly 300 also includes a mounting member 302, wherein the mounting member 302 may be a screw or a bolt, and the mounting portion 12 of the carrier member 1 is provided with mounting holes 123 (e.g., ...). Figures 21-22 As shown), the mounting hole 123 can be a through hole, countersunk hole, etc., and the mounting member 302 passes through the mounting hole 123 and the limiting member 301 of the bearing member 1.

[0134] During installation, the limiting member 301 is first pre-inserted into the crossbeam 2021 from the side away from the track assembly 100 and abuts against the limiting groove 122. The limiting member 301 is equivalent to adding a reinforcing rib to the crossbeam 2021, improving its structural strength. Then, the mounting member 302 is sequentially inserted from the side of the crossbeam 2021 facing the track assembly 100 into the mounting part 12 of the bearing member 1 and the limiting member 301. The limiting member 301 significantly improves the firmness and reliability, resulting in a high locking strength between the mounting member 302 and the limiting member 301, reducing the risk of deformation of the crossbeam 2021 during locking. Without the limiting member 301, if the bearing member 1 and the crossbeam 2021 are directly fixed by the mounting member 302, the mounting member 302 would need to pass through the entire steel pipe structure of the crossbeam 2021, and the locking force would flatten the crossbeam 2021, affecting its structural strength.

[0135] like Figures 22-23 As shown, the mounting part 12 of the bearing member 1 is provided with a mounting hole 123, and the limiting member 301 is provided with a threaded hole 3013 corresponding to the mounting hole 123. The length of the mounting member 302 can be less than or equal to the length of the limiting member 301. The mounting member 302 passes through the mounting hole 123 and is threaded to the threaded hole 3013, so that the bearing member 1 of the track assembly 100 can be stably fixed on the crossbeam 2021 of the shelf 200, ensuring the stability and reliability of the installation.

[0136] like Figures 22-23 As shown, the mounting assembly 300 also includes a locking member 303, wherein the locking member 303 may be a locking nut. The bearing member 1 is provided with a mounting hole 123. The limiting member 301 is provided with a through hole 3014 corresponding to the mounting hole 123. The mounting member 302 passes through the mounting hole 123, the through hole 3014 and the locking member 303. The locking member 303 is located on the side of the limiting member 301 away from the bearing member 1 and abuts against the limiting member 301, so that the bearing member 1 of the track assembly 100 can be stably fixed on the crossbeam 2021 of the shelf 200, ensuring the stability and reliability of the installation.

[0137] Since the locking member 303 is located on the side of the limiting member 301 away from the bearing member 1, that is, the locking member 303 is fixed on one side of the crossbeam 2021, and the load-bearing capacity of the locking member 303 is limited, without the limiting member 301, the entire weight of the shelf robot 400 would be concentrated on one side of the crossbeam 2021, resulting in poor stress state of the crossbeam 2021, and the crossbeam 2021 would deform due to the tension of the track assembly 100. In this embodiment, after the limiting member 301 is inserted into the crossbeam 2021, the mounting member 302 is inserted into the limiting member 301, so that the weight of the shelf robot 400 is distributed on the crossbeam 2021 through the limiting member 301, improving the uniformity of stress on the crossbeam 2021, reducing the possibility of deformation and failure of the crossbeam 2021, extending the service life of the shelf 200, and improving the stability of the shelf robot 400's movement.

[0138] The limiting member 301 may be provided with a threaded hole 3013, or a through hole 3014. Alternatively, two limiting members 301 may be provided with a threaded hole 3013 and a through hole 3014 respectively. Alternatively, the number of limiting members 301 may not be limited to two, with one part having a threaded hole 3013 and the other part having a through hole 3014. The specific form of the limiting member 301 can be adjusted according to actual production needs. As long as the corresponding mounting member 302 and locking member 303 are matched, they are all within the protection scope of this embodiment.

[0139] like Figure 23 As shown, the mounting assembly 300 also includes a gasket 304. The gasket 304 is sleeved on the outside of the limiting member 301 and located between the limiting boss 3011 and the locking member 303. The gasket 304 isolates the limiting boss 3011 and the locking member 303, preventing the locking member 303 from exerting a large compressive force on the limiting boss 3011, which could cause wear on the limiting boss 3011.
