Warehousing logistics system

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application 202311836787.0, filed on December 28, 2023, entitled “Warehouse Logistics System,” and the entire contents of that disclosure are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of logistics, and in particular to a warehousing logistics system. Background Art

[0004] In warehousing and logistics systems, cargo access systems are crucial for improving warehouse productivity and reducing logistics costs. Existing warehousing and logistics systems include rack-to-person systems and shuttle-type vertical warehouse systems. Rack-to-person systems require the entire rack to be moved in and out during access, which is time-consuming and labor-intensive. Shuttle-type vertical warehouse systems can accommodate both access and outbound cargo, but they are costly and typically require high floor space, reaching heights of 15-20 meters. In recent years, some easy-to-access, low-cost container access systems have emerged, but these are immature, resulting in low overall efficiency for warehousing and logistics systems and failing to meet demand.

[0024] One ends of the two supporting members are connected to each other to form a closed port; the other ends of the two supporting members are free to form an open port; and

[0025] Both ends of the two supports are free, forming open ports at both ends.

[0026] In some embodiments, the two supports are configured as one of the following:

[0027] One end of each of the two supports is connected to a support beam that is fixed to the shelf, and the other ends of the two supports are free, forming a single open channel between the two supports; and

[0056] As shown in Figure 1, an embodiment of the present disclosure provides a warehousing and logistics system, including a shelf 100, a cargo storage and retrieval mechanism 200, and a transfer vehicle 300. The shelf 100 is provided with multiple rows of storage locations for placing goods. The cargo storage and retrieval mechanism 200 is movably arranged relative to the shelf, and can be moved to a designated storage location of the shelf 100 to pick up the goods 600 thereon, and deliver the goods to a temporary storage location or a transfer vehicle, or can deliver the goods to a designated storage location of the shelf 100 and place the goods thereon; the transfer vehicle 300 is used to operate on the site of the warehousing and logistics system to transport goods, and can be navigated by a QR code, magnetic stripe, RFID or SLAM, and is used to deliver the goods to a temporary storage location or the cargo storage and retrieval mechanism 200. In this application, the goods 600 refers to an integral unit that can be transported or carried, and can be a box filled with goods, an empty box, or separately stored original packaged goods, etc.

[0057] In some embodiments, as shown in Figures 2 and 3, the shelf 100 is composed of vertical beams and horizontal beams and can be arranged in a single layer or multiple layers. Each layer of the shelf 100 can be provided with one or more storage locations for storing goods 600. The multiple storage locations on each layer can be separated from each other or can be interconnected.

[0058] In some embodiments, as shown in Figures 2 and 3, the warehousing and logistics system further comprises a cargo temporary storage mechanism 400. The cargo temporary storage mechanism 400 may be disposed below the lowest storage location of the shelf 100 and provided with a temporary storage location for temporarily storing cargo 600 from the transfer vehicle 300 and the cargo access mechanism 200. A low-level passage is formed below the cargo temporary storage mechanism 400, i.e., the low-level passage is located between the cargo temporary storage mechanism 400 and the floor of the warehousing and logistics system. The height of the low-level passage is higher than the height of the transfer vehicle 300 in a loaded state. The loaded state of the transfer vehicle 300 means that the transfer vehicle is loaded with cargo 600 but is not lifting the cargo 600. A high-level passage is provided below the lowest storage location and adjacent to the low-level passage. The high-level passage is located between the lowest storage location and the floor of the warehousing and logistics system. The height of the high-level passage is higher than the height of the transfer vehicle 300 in a lifted cargo state. The lifted cargo state of the transfer vehicle 300 means that the transfer vehicle has lifted the cargo.

[0059] In some embodiments, as shown in Figures 2 and 3, the cargo storage and retrieval mechanism 200 is suspended in the lane formed between two adjacent shelves 100. The cargo storage and retrieval mechanism 200 can move in the lane, and a lane passage is formed below the bottom of the cargo storage and retrieval mechanism 200. The lane passage is located between the bottom of the cargo storage and retrieval mechanism 200 and the ground of the storage and logistics system. The lowest height of the lane passage is greater than the height of the transfer vehicle 300 in an empty state. The transfer vehicle 300 in an empty state means that the transfer vehicle 300 is not loaded with cargo 600 and is not lifted. This allows the transfer vehicle 300 in an empty state to move on the entire ground in the lane without being blocked by the cargo temporary storage mechanism 400. In this way, the cargo temporary storage mechanism 400 and the transfer vehicle 300 in an empty state can move simultaneously in the lane without interfering with each other, thereby improving operational efficiency.

[0060] The understanding of the tunnel passage should be understood as the operational space formed by the cargo storage and retrieval mechanism 200 and the ground, including both the space along the extension direction of the tunnel and the space perpendicular to the direction of the tunnel. That is, when the transfer vehicle 300 travels along the extension direction of the tunnel, it can be considered to be passing through the tunnel passage, and when the transfer vehicle 300 crosses the tunnel perpendicular to the extension direction of the tunnel, it is also considered to be passing through the tunnel passage.

[0061] In some embodiments, it should be noted that the lowest height of the tunnel should be understood as the lowest height in hardware or the lowest height that can be controlled under normal operating conditions.

[0062] The cargo access mechanism can move relative to the shelf 100, for example, to a position adjacent to the shelf 100, so as to take the cargo 600 from the temporary storage position or the transfer vehicle 300 operating on the ground of the site, and then deliver the cargo 600 to the designated storage position on the shelf and place the cargo thereon, or deliver the cargo 600 taken from the designated storage position of the shelf 100 to the temporary storage position or to the transfer vehicle 300 operating on the site; the transfer vehicle 300 can deliver the cargo 600 it transports to the temporary storage position, or remove the cargo 600 from the temporary storage position of the shelf 100 and transport it away. Optionally, the cargo access mechanism 200 can be set on one of the shelves 100, or on other structures outside the shelf 100, for example, the cargo access mechanism 200 is arranged on a support frame connected to the ceiling or the ground of the warehouse logistics system, as long as the cargo access mechanism 200 is movable relative to the shelf 100 so as to be able to take and place cargo from each storage position of the shelf 100.

[0063] In some embodiments, as shown in Figure 3, since the heights of the low-level channel and the high-level channel are higher than the transfer vehicle 300 in an empty state, the transfer vehicle 300 in an empty state can travel on the ground of basically the entire site of the warehousing logistics system at any time without being blocked.

[0064] In some embodiments, as shown in Figures 2 and 3, the warehouse logistics system may include a single shelf 100 or multiple shelves 100 as shown in Figure 2. Multiple shelves 100 may be arranged in intervals, with operating spaces for cargo storage and retrieval mechanisms formed between adjacent shelves 100. One or more cargo storage and retrieval mechanisms 200 may be installed between adjacent shelves 100. Multiple cargo storage and retrieval mechanisms may be installed on one side of adjacent shelves 100, or on all adjacent shelves 100.

[0065] In some embodiments, as shown in FIG2 , the racks include single-row racks and double-row racks. Single-row racks refer to racks having two storage locations side by side in a direction perpendicular to the aisle, while double-row racks refer to racks having a single storage location in that direction. Within the racking area formed by the staggered arrangement of the racks, one or more staggered racking areas can be formed by staggering the single-row racks and the double-row racks. As shown in FIG3 , the two ends of the racking area are single-row racks, and the area between the single-row racks at the two ends is double-row racks.

[0066] In some embodiments, among the shelves arranged at intervals to form a shelf area, some shelves may have a cargo temporary storage mechanism 400 installed underneath to form only a low-level channel without a high-level channel, some shelves may not have a cargo temporary storage mechanism 400 underneath and only have a high-level channel, or have both a low-level channel and a high-level channel.

[0067] In some embodiments, the cargo temporary storage mechanism 400 includes a plurality of support members 82 arranged at intervals, and cargo 600 can be placed on storage spaces formed on two adjacent support members.

[0068] In some embodiments, as shown in Figures 4 and 6 , the first ends of multiple support members 82 are connected to the support beam 81, and the second ends of the multiple support members 82 are free ends. A one-way passage is formed between two adjacent support members 82. The support beam 81 is connected to the vertical beam of the shelf 100, and the first ends of the multiple support members 82 are adjacent to the lane. As shown in Figures 7a-7c , the transfer vehicle 300 moves to the high-level passage and lifts the cargo 600, placing the cargo 600 through the opening at the second end into the temporary storage space formed by the two support members 82.

[0069] In some embodiments, as shown in FIG8a , the first ends of the plurality of support members 82 are connected to the support beam 81, and the second ends of the plurality of support members 82 are free ends, forming a one-way passage between two adjacent support members 82. The second ends of the plurality of support members 82 are adjacent to the laneway, and the transfer vehicle 300 can move to the laneway, lift the cargo, and place the cargo on the two support members 82 through the openings at the second ends of the support members 82.

[0070] In some embodiments, as shown in FIG8b , multiple supports 82 are suspended between their ends on the lowest storage level of a shelf or supported between their ends on the floor of a site, whereby both ends of the multiple supports 82 are free ends, forming a two-way passage between two adjacent supports 82. This allows the transfer vehicle 300 to move to either the high-level passage or the lane and lift the cargo, placing the cargo 600 on at least two supports 82 through one of the openings at both ends of the two supports 82.

[0071] In some embodiments, as shown in Figures 4 and 5, the cargo access mechanism 200 includes a fork mechanism 201. The cargo access mechanism can be set on the shelf 100, or on other devices outside the shelf 100, such as on a supporting structure connected to the ceiling, side wall or floor of the warehouse logistics system, as long as the cargo access mechanism can move relative to the shelf 100 and take and place goods from the designated storage location thereon.

[0072] In some embodiments, as shown in Figures 3-5, the cargo access mechanism 200 may include a horizontally extending first rail TR1 and a vertically extending second rail TR2. The two first rails TR1 are spaced apart in the vertical direction. The first rail TR1 can be installed on the frame of the shelf 100, or it can be formed by the horizontal beam of the shelf 100. Optionally, when there are two second rails TR2, the two second rails TR2 are spaced apart in the transverse direction, and the fork mechanism 201 may have ends that are movably connected to the two rails TR2, and are located on the side of the operating plane formed by the two second rails TR2 away from the shelf 100. In addition, the fork mechanism 201 can be located between the two second rails TR2 so that the cargo 600 can pass through the gap between the two second rails TR2.

[0073] In some embodiments, as shown in Figures 3-5, the bottom end of the vertically extending second rail TR2 is higher than the transfer vehicle in the loaded state, so that the transfer vehicle in the loaded state will not be blocked by the bottom end of the second rail TR2, and by adjusting the bottom of the fork mechanism 201 to be higher than the transfer vehicle in the loaded state, the transfer vehicle in the loaded state can travel on basically the entire site ground of the warehousing logistics system without being blocked.

[0074] In some embodiments, as shown in Figures 4 and 5, the cargo access mechanism 200 may include a horizontally extending first rail TR1 and a vertically extending second rail TR2. The two first rails TR1 are spaced apart in the vertical direction. The first rail TR1 can be installed on the frame of the shelf 100, or it can be formed by the horizontal beam of the shelf 100. When there are two second rails TR2, the two second rails TR2 are spaced apart in the transverse direction, and the fork mechanism 201 may have ends that are respectively movably connected to the two rails TR2 and are located on the side of the operating plane formed by the two second rails TR away from the shelf 100. In addition, the fork mechanism 201 can be located between the two second rails TR2 so that the cargo 600 can pass through the gap between the two second rails TR2.

[0075] In some embodiments, as shown in Figure 9 , a fork mechanism 201 is mounted between two vertical rails TR2 and can move vertically along the two vertical rails TR2. The cargo access mechanism 200 includes a running mechanism 202, which is used to drive the two vertical rails TR2 for horizontal movement. Optionally, a running mechanism 202 is provided on both the upper and lower portions of the two vertical rails TR2.

[0076] In some embodiments, as shown in FIG4 , the fork mechanism 201 is lowered along the vertical rail to a lower position. When docking with the corresponding temporary storage position, the lowest height between the bottom of the fork mechanism and the ground is higher than that of the unloaded transfer vehicle. That is, during the operation of the entire warehousing and logistics system, the unloaded transfer vehicle will not interfere with other components in the entire system and can move freely within the ground space (warehouse plane). It should be noted that when the fork mechanism 201 docks with the temporary storage position, it may be at the lowest position of the vertical guide rail, that is, the docking position is the end of the travel of the fork mechanism 201 on the vertical guide rail. However, in practice, there may be a certain amount of residual travel. That is, during normal operation, the fork mechanism 201 is designated by the system control to be the docking position with the temporary storage position as the lowest position. In special circumstances, such as maintenance or loading and unloading, the fork mechanism 201 will be lowered to a position below the temporary storage position.

[0077] In some embodiments, as shown in Figure 9, the running mechanism 202 includes two rollers 2021 mounted on two vertical rails TR2, respectively. The rollers 2021 are located at the intersection of the vertical rails TR2 and the horizontal beam and are capable of rolling horizontally on the top surface of the horizontal beam intersecting the vertical rails TR2. At least one of the two rollers 2021 is a drive wheel, which is rotationally connected to the motor 203 and can move horizontally along the top surface of the horizontal beam, carrying the power supply devices of the two vertical rails TR2. Optionally, both rollers 2021 are drive wheels, or the rollers 2021 can be a drive wheel and a driven wheel.

[0078] In some embodiments, as shown in FIG9 , the travel mechanism 202 includes a guide device 2022 connected to at least one vertical track TR2, configured to guide the two vertical tracks TR2 to move horizontally along the horizontal beam. Optionally, the guide device 2022 includes a guide wheel 2023 that can roll along at least one side surface of the horizontal beam, where the side surface intersects the top surface of the horizontal beam.

[0079] In some embodiments, as shown in FIG9 , the cargo access mechanism 200 includes a power supply device 204 , which may be a battery for supplying power to the motor.

[0080] In some embodiments, as shown in FIG9 , the fork mechanism 201 includes a bracket 60 at the bottom. The bracket 60 is equipped with a storage and retrieval assembly 50. The storage and retrieval assembly 50 is used to transfer cargo between one of the storage and temporary storage locations and the fork mechanism. The fork mechanism 201 is capable of ensuring that the transfer surface of the storage and retrieval assembly 50 is substantially flush with each storage and temporary storage location. The bracket 60 includes a bent portion, which includes a vertical portion and a horizontal portion connected to each other. The vertical portion is movably connected to the vertical track, and the horizontal portion is lower than the vertical portion.

[0081] The storage and retrieval component 50 is a mechanism for directly taking and placing goods. Its structure can adopt the common hook-type picking component, fork-clamping picking component or lifting picking component in the field, etc. This patent does not make specific limitations.

[0082] In addition, in some embodiments, as shown in Figure 2, cargo storage and retrieval mechanisms 200 can be simultaneously set on the shelf surfaces on both sides of the same aisle. At this time, the cargo storage and retrieval mechanism 200 is installed on the shelf, and the storage and retrieval component 50 is movably installed on the bracket 60, so that the storage and retrieval component 50 can move relative to the bracket 60 in a direction perpendicular to the aisle or the side of the shelf. In this way, on the one hand, the two fork mechanisms 201 in the same aisle can adjust the position of the storage and retrieval component 50 during the horizontal movement to pass the vehicle. On the other hand, the distance between the storage and retrieval component 50 and the storage position, temporary storage position or transfer vehicle can be adjusted during the storage and retrieval process to facilitate storage and retrieval of goods and improve the stability of storage and retrieval of goods.

[0083] In some embodiments, as shown in FIG10 , the cargo storage and retrieval mechanism 200 includes a current collector 205 and a busbar 206 disposed within the horizontal beam. The busbar 206 is electrically connected to a power source, and when the current collector 205 and the busbar 206 are in sliding electrical connection, the battery 204 is charged. Optionally, the busbar 206 is partially disposed within the U-shaped groove of the horizontal beam. Optionally, the cross-section of the horizontal beam is an inverted U-shaped groove, with the busbar 206 disposed in a localized area of ​​the inverted U-shaped groove. The contact end of the busbar 206 faces downward and can mate with the upward-facing terminal of the current collector 205. When the current collector 205 is not in contact with the busbar 206 within the horizontal beam, the battery 204 supplies power to the motor 203. When the current collector 205 is in contact with the busbar 206 within the horizontal beam, the current collector 205 charges the battery 204.

[0084] In some embodiments, as shown in FIG11 , the bottom end of the vertical track TR2 is higher than the transfer vehicle 300 in the loaded state. By adjusting the height of the fork mechanism 201 to not be lower than the height of the transfer vehicle 300 in the loaded state, the transfer vehicle 300 in the loaded state can travel across substantially the entire floor area of ​​the warehouse logistics system. The fork mechanism 201 is configured to have a sunken structure. When the fork mechanism 201 moves to the bottom end of the vertical track TR2, the bottom end of the fork mechanism 201 is lower than the bottom end of the vertical track TR2. This ensures that the cargo at the bottom end of the fork mechanism 201 is substantially flush with the plane of the temporary storage location, and also ensures that the bottom end of the vertical track TR2 is higher than the bottom end of the fork mechanism 201. Furthermore, since the fork mechanism 201 is configured to have a sunken structure, the top end of the vertical track TR2 is higher than the top storage location to ensure that the cargo at the bottom end of the fork mechanism 201 is substantially flush with the top storage location. In addition, the fork mechanism 201 can make the goods on the bottom end of the fork mechanism 201 substantially flush with each storage location and temporary storage location, so as to facilitate the transportation of goods between the fork mechanism 201 and the storage location and temporary storage location.

[0085] In some embodiments, the fork mechanism 201 docks with a temporary storage location located below the shelf 200 to transfer goods. This is the lowest position of the fork mechanism 201 in its operating state, and while there may be room for further downward movement, under normal system operation, the fork mechanism 201 can theoretically only operate at or above this position. At this point, the fork mechanism 201 is located below the level of the unloaded transfer vehicle 300. Furthermore, the temporary storage location is higher than the loaded transfer vehicle 300. To ensure that the transfer vehicle 300 is not interfered with by the vertical track TR2, the bottom end of the vertical track TR2 in this embodiment is not lower than the height of the temporary storage location. As shown in Figures 4 and 11, its bottom end can be set flush with the bottom plane of the temporary storage mechanism. This ensures that the bottom end of the vertical track TR2 does not obstruct the transfer vehicle 300 even when the temporary storage location is higher than the loaded transfer vehicle 300. This ensures that the transfer vehicle 300 is not obstructed, whether traveling laterally or along the shelf extension, in both loaded and unloaded states.

[0086] In some embodiments, as shown in Figure 1, the warehousing and logistics system also includes a workstation 500, which is a workstation for sorting goods. An operator or a robotic arm can wait at the workstation for the transfer vehicle 300 to sort the goods on it. The transfer vehicle 300 is used to transport goods to the workstation 500 or to transport goods out of the workstation 500. Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
