[0053] like Figure 1 As shown, an embodiment of the utility model 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 cargo. 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 take the cargo 600 thereon, and deliver the cargo to a temporary storage location or a transfer vehicle, or can deliver the cargo to a designated storage location of the shelf 100 and place the cargo thereon; the transfer vehicle 300 is used to operate on the site of the warehousing and logistics system to transport cargo, and can be navigated by a QR code, a magnetic stripe, an RFID, or a SLAM, and is used to deliver the cargo to a temporary storage location or to the cargo storage and retrieval mechanism 200. In this application, cargo 600 refers to an integral unit that can be transported or carried, and can be a material box filled with cargo, an empty material box, or original packaged cargo stored separately, and the like.

[0054] In some embodiments, Figure 2 and 3 As shown, the shelf 100 is composed of vertical beams and horizontal beams, and can be arranged in a single layer or multiple layers, and each layer of the shelf 100 can be provided with one or more storage locations for storing goods 600. The multiple storage locations of each layer can be separated from each other or can be interconnected.

[0055] In some embodiments, Figure 2 and 3 As shown, the storage and logistics system further includes a cargo temporary storage mechanism 400, which can be arranged below the lowest storage position of the shelf 100 and is provided with a temporary storage position, which is used to temporarily store the cargo 600 from the transfer vehicle 300 and the cargo storage and retrieval mechanism 200, and a low-level passage is formed below the cargo temporary storage mechanism 400, that is, the low-level passage is located between the cargo temporary storage mechanism 400 and the ground of the storage and logistics system, and the height of the low-level passage is higher than the height of the transfer vehicle 300 in the cargo-loaded state, and the transfer vehicle 300 in the cargo-loaded state means that the transfer vehicle carries the cargo 600 but does not lift the cargo 600. A high-level passage is provided below the lowest storage position and adjacent to the low-level passage, and the high-level passage is located between the lowest storage position and the ground of the storage and logistics system, and the height of the high-level passage is higher than the height of the transfer vehicle 300 in the cargo-lifting state, and the transfer vehicle 300 in the cargo-lifting state means that the transfer vehicle lifts the cargo.

[0056] In some embodiments, Figure 2 and 3 As shown, the cargo storage and retrieval mechanism 200 is arranged in a suspended manner 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. The transfer vehicle 300 in an empty state can 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 in the lane at the same time without interfering with each other, thereby improving the operation efficiency.

[0057] The understanding of the alley 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 alley and the space perpendicular to the direction of the alley. That is, when the transfer vehicle 300 travels along the extension direction of the alley, it can be considered to be passing through the alley passage, and when the transfer vehicle 300 crosses the alley perpendicular to the extension direction of the alley, it is also considered to be passing through the alley passage.

[0058] In some embodiments, it should be noted that the lowest height of the tunnel passage should be understood as the lowest height that may be in hardware or the lowest height that can be controlled under normal operating conditions.

[0059] The cargo storage and retrieval 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 running on the ground of the site, and then deliver the cargo 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 the transfer vehicle 300 running on the site; the transfer vehicle 300 can deliver the cargo 600 it transports to the temporary storage position, or take the cargo 600 from the temporary storage position of the shelf 100 and transport it away. Optionally, the cargo storage and retrieval mechanism 200 can be set on one of the shelves 100, or on other structures outside the shelf 100, for example, the cargo storage and retrieval mechanism 200 is arranged on a support frame connected to the ceiling or the ground of the storage logistics system, as long as the cargo storage and retrieval 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.

[0060] In some embodiments, Figure 3As shown, 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 the entire site of the warehousing logistics system at any time without being blocked.

[0061] In some embodiments, Figure 2 and 3 As shown, the warehouse logistics system may include a single shelf 100 or Figure 2 The plurality of shelves 100 shown in the figure can be arranged at intervals, and an operating space for a cargo storage and retrieval mechanism can be formed between adjacent shelves 100. One or more cargo storage and retrieval mechanisms 200 can be set between adjacent shelves 100. The plurality of cargo storage and retrieval mechanisms can be set on one side of the adjacent shelves 100, or can be set on all adjacent shelves 100.

[0062] In some embodiments, Figure 2 As shown, the shelves include single-row shelves and double-row shelves. Single-row shelves refer to shelves with two storage locations side by side in a direction perpendicular to the lane, and single-row shelves refer to shelves with a single storage location in this direction. In the shelf area formed by the shelves arranged at intervals, one or more intervals in the single-row shelves and the double-row shelves can be used to form a shelf area, such as Figure 3 As shown, there are single-row shelves at both ends of the shelf area, and double-row shelves between the single-row shelves at both ends.

[0063] In some embodiments, among the shelves arranged at intervals to form a shelf area, some shelves may have a cargo temporary storage mechanism 400 disposed 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 may have both a low-level channel and a high-level channel.

[0064] In some embodiments, the cargo temporary storage mechanism 400 includes a plurality of support members 82 arranged at intervals, and the cargo 600 can be placed on the storage positions formed on two adjacent support members.

[0065] In some embodiments, Figure 4 and 6 As shown, the first ends of the plurality of support members 82 are connected to the support beam 81, the second ends of the plurality of support members 82 are free ends, a one-way channel 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 plurality of support members 82 are adjacent to the lane. Figure 7a-7c As shown, the transfer vehicle 300 moves to the high-level channel and lifts the cargo 600, and places the cargo 600 on a temporary storage position formed by two support members 82 through the opening at the second end.

[0066] In some embodiments, Figure 8aAs shown, the first ends of the plurality of support members 82 are connected to the support beam 81, the second ends of the plurality of support members 82 are free ends, and a one-way passage is formed between two adjacent support members 82. The second ends of the plurality of support members 82 are adjacent to the lane, and the transfer vehicle 300 can move to the lane and 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.

[0067] In some embodiments, Figure 8b As shown, a plurality of support members 82 are suspended between the two ends on the lowest storage position of the shelf or supported between the two ends on the ground of the site, so that both ends of the plurality of support members 82 are free ends, and a two-way passage is formed between two adjacent support members 82. The transfer vehicle 300 can move to any one of the high-level passage and the lane and lift the goods, and place the goods 600 on at least two support members 82 through one of the openings at the two ends of the two support members 82.

[0068] In some embodiments, Figure 4 and 5 As shown, 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 being installed 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 be moved relative to the shelf 100 and take and place goods from designated storage locations thereon.

[0069] In some embodiments, Figure 3-5 As shown, the cargo access mechanism 200 may include a first rail TR1 extending horizontally and a second rail TR2 extending vertically. The two first rails TR1 are arranged at intervals in the vertical direction. The first rail TR1 may be installed on the frame of the shelf 100, or may be formed by a horizontal beam of the shelf 100. Optionally, when the number of the second rails TR2 is two, the two second rails TR2 are arranged at intervals in the transverse direction, and the fork mechanism 201 may have ends respectively connected to the two rails TR2 for movement, and is located on a side of the running plane formed by the two second rails TR2 away from the shelf 100. Moreover, the fork mechanism 201 may be located between the two second rails TR2 so that the cargo 600 passes through the gap between the two second rails TR2.

[0070] In some embodiments, Figure 3-5As shown, the bottom end of the vertically extended 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.

[0071] In some embodiments, Figure 4 and 5 As shown, the cargo access mechanism 200 may include a first track TR1 extending horizontally and a second track TR2 extending vertically. The two first tracks TR1 are arranged at intervals in the vertical direction. The first track TR1 may be installed on the frame of the shelf 100, or may be formed by a horizontal beam of the shelf 100. When the number of the second tracks TR2 is two, the two second tracks TR2 are arranged at intervals in the transverse direction, and the fork mechanism 201 may have ends respectively connected to the two tracks TR2 for movement, and is located on a side of the running plane formed by the two second tracks TR away from the shelf 100.

It should be noted here that when the fork mechanism 201 docks with the temporary storage position, it may be 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, it is also possible to leave a certain amount of remaining 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, and in special circumstances, such as maintenance or loading and unloading, the fork mechanism 201 will be lowered to a position lower than the temporary storage position.

At least one of the two rollers 2021 is a driving wheel, and the driving wheel 2021 is connected to the motor 203 for rotational driving, and the driving wheel 2021 can move horizontally along the top surface of the horizontal beam with the two vertical rail TR2 power supply devices. Optionally, both rollers 2021 are driving wheels, or are a driving wheel and a driven wheel.

[0075] In some embodiments, Fig. 9 As shown, the walking mechanism 202 includes a guide device 2022 connected to at least one vertical track TR2, which is used to guide the two vertical tracks TR2 to move horizontally along the horizontal beam. Optionally, the guide device 2022 includes a guide wheel 2023, which can roll along at least one side of the horizontal beam, and the side of the horizontal beam intersects with the top surface.

[0076] In some embodiments, Fig. 9 As shown, the cargo storage and retrieval mechanism 200 includes a power supply device 204, which may be a battery for supplying power to the motor.

[0077] In some embodiments, Fig. 9 As shown, the fork mechanism 201 includes a bracket 60 located at the bottom, and the bracket 60 is provided with a storage and retrieval assembly 50, which is used to transfer goods between one of the storage position and the temporary storage position and the fork mechanism, and the fork mechanism 201 can make the transmission surface of the storage and retrieval assembly 50 substantially flush with each storage position and the temporary storage position. The bracket 60 includes a bending portion, and the bending portion includes a connected vertical portion and a horizontal portion, the vertical portion is movably connected to the vertical track, and the horizontal portion is lower than the vertical portion.

[0078] The storage and retrieval component 50 is a mechanism for directly placing and retrieving 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.

[0079] In addition, in some embodiments, Figure 2As shown, cargo storage and retrieval mechanisms 200 can be simultaneously arranged 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 positions of the two fork mechanisms 201 in the same aisle can be adjusted during the horizontal movement to avoid vehicles, and 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 and improve the stability of storage and retrieval.

[0080] In some embodiments, Fig.10 As shown, the cargo storage and retrieval mechanism 200 includes a current collector 205, a busbar 206 is arranged in the horizontal beam, and the busbar 206 is electrically connected to the power supply. When the current collector 205 is electrically connected to the busbar 206 by sliding, the battery 204 is charged. Optionally, a busbar 206 is partially provided in the U-shaped groove of the horizontal beam. Optionally, the cross section of the horizontal beam is an inverted U-shaped groove, and a busbar 206 is provided in a local area of ​​the inverted U-shaped groove, and the contact end of the busbar 206 is downward and can be docked with the terminal of the current collector 205 upward.

[0081] In some embodiments, Fig.11 As shown, the bottom end of the vertical track TR2 is higher than the transfer vehicle 300 in the loading state. By adjusting the height of the fork mechanism 201 not lower than the height of the transfer vehicle 300 in the loading state, the transfer vehicle 300 in the loading state can travel on the substantially entire ground range of the storage logistics system. The fork mechanism 201 is configured to have a sinking 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. On the one hand, it ensures that the goods on the bottom end of the fork mechanism 201 are substantially flush with the plane of the temporary storage position, and on the other hand, it ensures that the bottom end of the vertical track TR2 is higher than the bottom end of the fork mechanism 201. At the same time, since the fork mechanism 201 is configured to have a sinking structure, in order to ensure that the goods on the bottom end of the fork mechanism 201 are substantially flush with the uppermost storage position, the top end of the vertical track TR2 is higher than the uppermost storage position. In addition, the fork mechanism 201 can make the goods on the bottom end of the fork mechanism 201 substantially flush with each storage position and temporary storage position, so as to facilitate the transportation of goods between the fork mechanism 201 and the storage position and temporary storage position.

[0082] In some embodiments, the fork mechanism 201 docks with the temporary storage position provided below the shelf 200 to transfer goods. At this time, the fork mechanism 201 is in the lowest position in the working state. There may be space to continue to move downward, but under the normal operation of the system, the fork mechanism 201 can theoretically only operate at this position and above. At this time, the bottom of the fork mechanism 201 is higher than the transfer vehicle 300 in the empty state. At the same time, the height of the temporary storage position is higher than the transfer vehicle 300 in the loaded state. In order to ensure that the transfer vehicle 300 is not interfered with by the vertical track TR2, the bottom end height of the vertical track TR2 in this embodiment is not lower than the height of the temporary storage position. Figure 4 and Fig.11 As shown, its bottom height can be set to be flush with the lower plane of the temporary storage mechanism, so that when the height of the temporary storage position is higher than the transfer vehicle 300 in the loaded state, it can be stably ensured that the bottom height of the vertical track TR2 will not block the transfer vehicle 300, that is, the transfer vehicle 300 will not be hindered whether it is moving horizontally or along the extension direction of the shelf in the loaded state or the unloaded state.

[0083] In some embodiments, Figure 1 As shown, the warehousing logistics system also includes a workstation 500, which is a station for sorting goods. An operator or a mechanical arm can wait at the station for the transfer vehicle 300 to sort the goods on it. The transfer vehicle 300 is used to transport the goods to the workstation 500 or to transport the goods from the workstation 500.
