Description

Technical Field

[0001] The present disclosure relates to the field of logistics, and particularly to a storage logistics system.

Background Art

[0002] In a storage logistics system, an article in-out system is an important technology for improving storage production efficiency and reducing logistics costs. Existing storage logistics systems include a shelf-to-person system and a shuttle stereoscopic storage system. In the in-out process of the shelf-to-person system, it is essential to take in and out the entire shelf, which is time-consuming and laborious. In the shuttle stereoscopic storage system, articles can be taken in and out, but the cost is high, and the height usually reaches 15 to 20 meters, so the requirements for the site are high. In recent years, several container in-out systems that are easy to access and have low costs have emerged, but they are not mature. The overall efficiency of the storage logistics system is low, and it is impossible to meet the requirements.

Summary of the Invention

Means for Solving the Problems

[0003] In order to improve the above technical defects, the present disclosure provides a storage logistics system including a shelf including a horizontal beam and a vertical beam and provided with a plurality of rows of storage positions for arranging articles, an article access mechanism movably arranged relative to the shelf for taking out an article from a designated storage position and placing the article on the designated storage position, and a transfer vehicle configured to transport articles on the site of the storage logistics system.

[0004] In some embodiments, the article access mechanism is movably arranged relative to the shelf in a bottom hanging manner.

[0005] In some embodiments, the article access mechanism is attached to the shelf.

[0006] In some embodiments, the storage and logistics system includes an article temporary storage mechanism where a temporary storage position is provided. The temporary storage position is configured to temporarily store articles from the transfer vehicle and the article access mechanism. The article temporary storage mechanism is disposed below the storage position located at the lowermost row, higher than the transfer vehicle in the article-loaded state. A low-ground high passage is formed between the article temporary storage mechanism and the ground of the storage and logistics system, and the low-ground high passage is higher than the transfer vehicle in the article-transporting state. Thus, the transfer vehicle carrying articles can pass under the article temporary storage mechanism.

[0007] In some embodiments, when the article access mechanism is docked at a designated position located below the lowermost storage position of the shelf, the lowest height of the bottom of the article access mechanism exceeds that of the transfer vehicle in the unloaded state. Thus, the article access mechanism is configured such that the transfer vehicle in the unloaded state can pass under the article access mechanism.

[0008] In some embodiments, the article access mechanism includes a vertical track. The vertical track can move horizontally with respect to the shelf, and the lower end of the vertical track is higher than the transfer vehicle in the article-loaded state. Thus, the transfer vehicle in the article-loaded state can pass under the lower end of the vertical track.

[0009] In some embodiments, the vertical track is vertically arranged on one side of the shelf. The article access mechanism includes a fork mechanism. The fork mechanism is arranged on the vertical track so as to be vertically movable to move to a designated storage position to take out and place articles.

[0010] In some embodiments, when the fork mechanism moves downward along the vertical track to the docking position, the lowest height from the bottom of the fork mechanism to the ground exceeds that of the transfer vehicle in the unloaded state. The bottom of the fork mechanism is configured such that the docking position is the position when the fork mechanism is docked at a designated position below the lowermost storage position of the shelf.

[0011] In some embodiments, the bottom of the fork mechanism is configured to be positioned at the lowest position of the bottom of the article access mechanism when the fork mechanism moves to the lower end of the vertical track.

[0015] In some embodiments, the operating mechanism includes a sliding contact line locally disposed in a groove of the horizontal beam and a motor that can be electrically connected to the sliding contact line through a current collector.

[0016] In some embodiments, the operating mechanism includes a driving wheel connected to the vertical track, the driving wheel is disposed on the upper surface of the horizontal beam, and is connected to the motor to drive.

[0017] In some embodiments, the operating mechanism includes a battery electrically connected to the sliding contact line.

[0018] In some embodiments, the storage logistics system includes a guide wheel connected to the vertical track, the guide wheel is disposed on at least one side surface of the horizontal beam, and the side surface intersects the upper surface of the horizontal beam.

[0019] In some embodiments, the storage and logistics system includes an article temporary storage mechanism where a temporary storage position is provided. The temporary storage position is configured to temporarily store articles from the transfer vehicle and the article access mechanism, and the article temporary storage mechanism is disposed below the storage position located at the lowermost row.

[0020] In some embodiments, the article temporary storage mechanism includes a plurality of support pieces arranged at intervals in the horizontal direction. The temporary storage position includes two adjacent support pieces, and the two adjacent support pieces form the temporary storage position. The two support pieces are configured in one of the following ways.

[0021] One ends of the two support pieces are connected to each other to form a closed port, and the other ends of the two support pieces are free ends so as to form an open port.

[0022] Both ends of the two support pieces are free ends, and open ports are formed at both ends.

[0023] In some embodiments, the two support pieces are configured in one of the following ways.

[0024] One end of each of the two support pieces is connected to a support beam, the support beam is fixed to the shelf, and the other ends of the two support pieces are free ends so as to form a single open passage between the two support pieces.

[0025] The space between both ends of the two support pieces is connected to or supported by the bottom layer of the storage position of the shelf in a floating manner and is connected to the ground of the storage and logistics system. Both ends of the two support pieces are free ends so as to form two open passages between the two support pieces.

[0026] In some embodiments, the storage and logistics system includes at least two rows of spaced-apart shelves. A lane is formed between two adjacent rows of the plurality of shelves. The article access mechanism moves in the lane, and a lane passage is formed between the bottom of the article access mechanism and the ground of the storage and logistics system. The minimum height of the lane passage exceeds that of the transfer vehicle in the unloaded state.

[0027] In some embodiments, the transfer vehicle has an article lifting function, and a high ground high passage is formed between the lowermost row of the storage positions and the ground of the storage logistics system, and the high ground high passage is higher than the transfer vehicle in the article lifting state.

[0028] In some embodiments, the fork mechanism includes an access assembly that transfers articles between one of the storage position and the temporary storage position and the fork mechanism, and the fork mechanism is configured to position the transmission surface of the access assembly and each of the storage position and the temporary storage position substantially on the same plane.

[0033] The article access mechanism is attached to one side of the shelf, has a high operating speed and is stable, and is easy to use for attachment, so that the entry and landing speeds of the entire system are increased.

[0034] The high passageway below the article temporary storage mechanism is higher than the transfer vehicle in the article-loaded state. The transfer vehicle in the article-loaded state is driven under the article temporary storage mechanism and is allowed to pass under the article temporary storage mechanism. By adjusting the fork mechanism to be higher than the transfer vehicle in the article-loaded state, the transfer vehicle in the article-loaded state can operate basically the entire grand range of the storage logistics system without any obstacles, thereby improving the operating efficiency of the entire storage logistics system.

[0035] A lane is formed under the article access mechanism within the lane, and the minimum height of the lane passage is higher than that of the transfer vehicle in the unloaded state. Thus, the transfer vehicle in the unloaded state can operate basically the entire grand range of the storage logistics system at any time without any obstacles, thereby improving the operating efficiency of the entire storage logistics system.

[0039] Hereinafter, various typical embodiments of the present invention will be described in detail with reference to the accompanying drawings. The description of the typical embodiments is merely illustrative and is not intended to limit the present disclosure, its application examples, or uses in any way. The present disclosure can be implemented in many different forms and is not limited to the embodiments described in the present disclosure. The embodiments are provided so that the present disclosure will be comprehensive and complete and the scope of the present disclosure will be fully conveyed to those skilled in the art. Unless otherwise specified, the relative arrangements of the components and steps shown in the embodiments, the composition of the materials, the mathematical formulas, and the numerical values are to be construed as merely illustrative and not as imposing limitations.

[0040] In the present disclosure, terms of the same kind such as "first", "second", etc. do not indicate any order, quantity, or importance, and are only used to distinguish different parts. Terms of the same kind such as "including" and "containing" mean that the element before this term covers the elements listed after this term without excluding the possibility of covering other elements. Terms such as "above", "below", "left", "right", etc. are only used to indicate relative positional relationships. After the absolute position of the object being described changes, the relative positional relationship may change accordingly.

[0041] In the present invention, when it is described that a specific device is positioned between a first device and a second device, there may or may not be a device intervening between the specific device and the first device or the second device. When it is described that a specific device is connected to another device, the specific device may be directly connected to the other device without using an intervening device, or the specific device may have an intervening device without being directly connected to the other device.

[0042] All terms used in the present disclosure (including technical terms and scientific terms) have the same meaning as understood by those skilled in the technical field to which the present disclosure pertains, unless otherwise specifically defined. For example, terms defined in a general dictionary are naturally construed as having a meaning that does not conflict with the meaning of the relevant technical term, and it is natural that they are not construed in an idealized meaning or an extremely formal meaning unless explicitly defined in the present disclosure.

[0043] As shown in FIG. 1, in an embodiment of the present disclosure, a storage logistics system including a shelf 100, an article access mechanism 200, and a transfer vehicle 300 is provided. The shelf 100 is provided with a plurality of rows of storage positions for placing articles. The article access mechanism 200 is arranged to be movable relative to the shelf, moves to a designated storage position of the shelf 100, takes out the article 600 at the storage position, and conveys the taken-out article to a temporary storage position or the transfer vehicle, or conveys the article to a designated storage position of the shelf 100 and places it at the storage position. The transfer vehicle 300 is configured to operate on the site of the storage logistics system to convey articles, and may be configured to convey articles to a temporary storage position or the article access mechanism 200 through a QR code (registered trademark), a magnetic stripe, RFID, or SLAM navigation. The article 600 in the present application refers to an essential unit that can be transported, i.e., carried, and may be a work bin containing articles, an empty work bin, or individually stored and original packaged articles.

[0044] In some embodiments, as shown in FIGS. 2 and 3, the shelf 100 includes a vertical beam and a horizontal beam, and may be arranged in a single layer or multiple layers. One or more storage positions for storing the article 600 may be provided on each layer of the shelf 100 for storing articles. Each layer of the plurality of storage positions may be separated from each other or may communicate with each other.

[0045] In some embodiments, as shown in FIGS. 2 and 3, the storage and logistics system further includes an article temporary storage mechanism 400. The article temporary storage mechanism 400 is disposed below the lowermost layer of the storage positions of the shelves 100. The article temporary storage mechanism 400 may be provided with temporary storage positions, and the temporary storage positions are configured to temporarily store articles 600 from the transfer vehicle 300 and the article access mechanism 200. A low-ground high passage is formed below the article temporary storage mechanism 400, that is, the low-ground high passage is located between the article temporary storage mechanism 400 and the ground of the storage and logistics system. The height of the low-ground high passage exceeds the height of the transfer vehicle 300 in the article-loaded state, and the transfer vehicle 300 in the article-loaded state means that the transfer vehicle transports the article 600 but does not lift the article 600. A high-ground high passage is formed below the lowermost layer of the storage positions and adjacent to the low-ground high passage. The high-ground high passage is located between the lowermost layer of the storage positions and the ground of the storage and logistics system. The height of the high-ground high passage exceeds the height of the transfer vehicle 300 in the article-lifted state, and the transfer vehicle 300 in the article-lifted state means that the transfer vehicle lifts the article.

[0046] In some embodiments, as shown in FIGS. 2 and 3, the article access mechanism 200 is disposed in a floating manner in the lane formed between two adjacent shelves 100. The article access mechanism 200 can run in the lane. A lane passage is formed below the bottom of the article access mechanism 200. The lane passage is located between the bottom of the article access mechanism 200 and the ground of the storage and logistics system. The minimum height of the lane passage exceeds the height of the transfer vehicle 300 in the unloaded state. The transfer vehicle 300 in the unloaded state means that no article 600 is loaded on the transfer vehicle 300 and the transfer vehicle 300 is not in the lifted state, so that the transfer vehicle 300 in the unloaded state can run through the entire ground of the lane without being blocked by the article temporary storage mechanism 400. Therefore, the article temporary storage mechanism 400 and the transfer vehicle 300 in the unloaded state can run in the lane simultaneously without interfering with each other, thereby improving the operation efficiency.

[0047] The lane passage is naturally understood as the space formed between the article access mechanism 200 and the ground, that is, the space including the space along the direction in which the lane extends and the space perpendicular to the lane direction. That is, it may be considered that the transfer vehicle 300 passes through the lane passage when traveling along the direction in which the lane extends, and it may also be considered that the transfer vehicle 300 passes through the lane passage when crossing the lane perpendicular to the direction in which the lane extends.

[0048] It should be noted that in some embodiments, the minimum height of the lane passage is the minimum height on the hardware, that is, the minimum height that can be adjusted in the normal operating state.

[0049] The article access mechanism can move relative to the shelf 100. For example, it can move from the temporary storage position or from the transfer vehicle 300 traveling on the ground of the site to a position adjacent to the shelf 100 to take out the article 600, and then convey the article to the designated storage position of the shelf and place the article at the storage position, or convey the article 600 taken out from the designated storage position of the shelf 100 to the temporary position or to the transfer vehicle 300 traveling on the site. The transfer vehicle 300 can convey the transported article 600 to the temporary storage position or remove the temporary storage position of the shelf 100 and transport it to a place away from the temporary storage position. Optionally, if the article access mechanism 200 can move relative to the shelf 100 and take out and place articles from each storage position of the shelf 100, the article access mechanism 200 may be arranged on one shelf 100 or on other structures other than the shelf 100. For example, the article access mechanism 200 is arranged on the suspended ceiling of the storage logistics system or on a support frame connected to the ground.

[0050] In some embodiments, as shown in FIG. 3, since the low-ground high passage and the high-ground high passage are higher than the unloaded transfer vehicle 300, the unloaded transfer vehicle 300 can operate at any time without basically being blocked by the entire ground of the site of the storage logistics system.

[0051] In some embodiments, as shown in FIGS. 2 and 3, the storage and logistics system may include a single shelf 100 or a plurality of shelves 100 as shown in FIG. 2. The plurality of shelves 100 may be arranged at intervals, and an operating space for the article access mechanism is formed between adjacent shelves 100. One or more article access mechanisms 200 may be arranged between adjacent shelves 100. The plurality of article access mechanisms may be arranged on one of the adjacent shelves 100 or on both of the adjacent shelves 100.

[0052] In some embodiments, as shown in FIG. 2, the shelf includes a single-row shelf and a double-row shelf. The single-row shelf has two storage positions arranged in parallel in a direction perpendicular to the lane, and the single-row shelf has separate storage positions in that direction. When a shelf area is formed by shelves arranged at intervals, as shown in FIG. 3, one or more of the single-row shelves and double-row shelves may be arranged at intervals to form a shelf area. Both ends of the shelf area are single-row shelves, and there is a double-row shelf between the single-row shelves at both ends.

[0053] In some embodiments, in the case of shelves arranged at intervals to form a shelf area, the article temporary storage mechanism 400 may be arranged under some of the shelves so that only a high passage on a low ground is formed without forming a high passage on a high ground. Under some of the shelves, the article temporary storage mechanism 400 is not arranged, and only a high passage on a high ground is provided, or a high passage on a low ground and a high passage on a high ground are provided.

[0054] In some embodiments, the temporary storage mechanism 400 includes a plurality of support pieces 82 arranged at intervals, and the article 600 may be placed at the storage position formed between two adjacent support pieces.

[0055] In some embodiments, as shown in FIGS. 4 and 6, the first ends of the plurality of support pieces 82 are connected to the support beam 81, the second ends of the plurality of support pieces 82 are free ends, a one-way passage is formed between two adjacent support pieces 82, the support beam 81 is connected to the vertical beam of the shelf 100, and the first ends of the plurality of support pieces 82 are adjacent to the lane. As shown in FIGS. 7a to 7c, the transfer vehicle 300 moves to the high passage on the high ground to lift the article 600, and places the article 600 through the opening at the second end at the temporary storage position formed by the two support pieces 82.

[0056] In some embodiments, as shown in FIG. 8a, the first ends of the plurality of support pieces 82 are connected to the support beam 81, the second ends of the plurality of support pieces 82 are free ends, and a one-way passage is formed between two adjacent support pieces 82. The second ends of the plurality of support pieces 82 are adjacent to the lane. The transfer vehicle 300 can move to the lane to lift the article and place the article on the two support pieces 82 through the opening at the second end of the support piece 82.

[0057] In some embodiments, as shown in FIG. 8b, since both ends of the plurality of support pieces 82 are hung or supported on the ground of the site in a floating manner at the lowermost layer of the storage position of the shelf, both ends of the plurality of support pieces 82 become free ends, and a two-way passage is formed between two adjacent support pieces 82. Therefore, the transfer vehicle 300 can move to either the high passage on the high ground or the lane to lift the article, and place the article 600 on at least two support pieces 82 through one of the two openings at both ends of the two support pieces 82.

[0058] In some embodiments, as shown in FIGS. 4 and 5, the article access mechanism 200 includes a fork mechanism 201. The article access mechanism may be arranged on the shelf 100 or on other devices other than the shelf 100 as long as the article access mechanism can move relative to the shelf 100 and take out and place articles from the designated storage positions on the shelf 100. For example, it may be attached to a support structure connected to the ceiling, side wall or floor of the storage logistics system.

[0059] In some embodiments, as shown in FIGS. 3 to 5, the article 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 attached to the frame of the shelf 100 or may be formed by the horizontal beams of the shelf 100. Optionally, when the number of the second tracks TR2 is two, the two second tracks TR2 are arranged at intervals in the lateral direction, and the fork mechanism 201 may have ends movably connected to the two tracks TR2 respectively, and is located on one side away from the shelf 100 of the operation plane formed by the two second tracks TR2. Further, the fork mechanism 201 may be located between the two second tracks TR2 so that the article 600 can pass through the gap between the two second tracks TR2.

[0060] In some embodiments, as shown in FIGS. 3 to 5, since the lower end of the vertically extending second track TR2 is higher than the transfer vehicle in the article-loaded state, the transfer vehicle in the article-loaded state is not blocked by the lower end of the second track TR2. Further, under the condition that the bottom of the fork mechanism 201 is adjusted to be higher than the transfer vehicle in the article-loaded state, the transfer vehicle in the article-loaded state can operate without being blocked by the entire site of the storage logistics system.

[0061] In some embodiments, as shown in FIGS. 4 and 5, the article access mechanism 200 may include a first track TR1 extending horizontally and a second track TR2 extending vertically. Two first tracks TR1 are arranged at intervals in the vertical direction. The first track TR1 may be attached to the frame of the shelf 100 or may be formed by the 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 lateral direction, and the fork mechanism 201 may have ends movably connected to the two tracks TR2 respectively, and is positioned on one side away from the shelf 100 of the operating plane formed by the two tracks TR2. Further, the fork mechanism 201 may be positioned between the two second tracks TR2 so that the article 600 can pass through the gap between the two second tracks TR2.

[0062] In some embodiments, as shown in FIG. 9, the fork mechanism 201 is attached between two vertical tracks TR2 and can move vertically along the two vertical tracks TR2. The article access mechanism 200 includes an operating mechanism 202, and the operating mechanism 202 is configured to drive the two vertical tracks TR2 to move horizontally. Optionally, one operating mechanism 202 is provided at each of the upper and lower parts of the two vertical tracks TR2.

[0063] In some embodiments, as shown in FIG. 4, when the fork mechanism 201 descends along the vertical track to the lower position and is docked with the corresponding temporary storage position, the minimum height from the lower part of the fork mechanism to the ground is higher than that of the unloaded transfer vehicle, that is, the unloaded transfer vehicle does not interfere with other components in the whole system during the operation process of the whole storage logistics system, and can freely move on the ground area (warehouse floor). Here, it should be noted that when the fork mechanism 201 is docked with the temporary storage position, the fork mechanism 201 may be at the lowest position of the vertical guide rail, that is, the docking position is at the end of the stroke of the fork mechanism 201 on the vertical guide rail. However, in practice, a certain amount of residual stroke may be ensured, that is, in the normal operation process, the fork mechanism 201 is instructed through system control to set the docking position of the temporary storage position to the lowest position, while in special situations such as maintenance and loading / unloading, the fork mechanism 201 can be lowered to a position lower than the temporary storage position.

[0064] In some embodiments, as shown in FIG. 9, the running mechanism 202 includes two rollers 2021 respectively attached to two vertical tracks TR2. The rollers 2021 are arranged at the intersection position of the vertical track TR2 and the horizontal beam, and can roll horizontally on the upper surface of the horizontal beam intersecting with the vertical track TR2. At least one of the two rollers 2021 is a driving wheel. The driving wheel 2021 is in a rotational driving connection state with the motor 203, and the driving wheel 2021 can drive the power supply device of the two vertical tracks TR2 to move horizontally along the upper surface of the horizontal beam. Optionally, the two rollers 2021 can be driving wheels or a combination of a driving wheel and a driven wheel.

[0065] In some embodiments, as shown in FIG. 9, the operating mechanism 202 includes a guiding device 2022 connected to at least one vertical track TR2 and configured to guide two vertical tracks TR2 to move horizontally along a horizontal beam. Optionally, the guiding device 2022 includes guiding wheels 2023 that can roll along at least one side surface of the horizontal beam, and the side surface of the horizontal beam intersects the upper surface.

[0066] In some embodiments, as shown in FIG. 9, the article access mechanism 200 includes a power supply device 204, and the power supply device 204 may be a battery that supplies power to a motor.

[0067] In some embodiments, as shown in FIG. 9, the fork mechanism 201 includes a bracket 60 located at the bottom, and an access assembly 50 is provided on the bracket 60. The access assembly 50 is configured to transfer an article between one of a storage position and a temporary storage position and the fork mechanism. The fork mechanism 201 can position the transfer surface of the access assembly 50 and each of the storage position and the temporary storage position substantially on the same plane. The bracket 60 includes a bent portion, and the bent 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.

[0068] The access assembly 50 is a mechanism for directly taking out and placing articles. The access assembly 50 may employ a hook-type pickup assembly, a fork clamp-type pickup assembly, a lifting-type pickup assembly, etc., and is not particularly limited in this patent.

[0069] Furthermore, in some embodiments, as shown in FIG. 2, the article access mechanism 200 may be disposed on the surfaces of the shelves on both sides of the same lane. At this time, the article access mechanism 200 is attached to the shelf, and the access assembly 50 is movably attached to the bracket 60. Thereby, the access assembly 50 can move in a direction perpendicular to the lane or the side surface of the shelf with respect to the bracket 60. Thus, on the one hand, the two fork mechanisms 201 within the same lane adjust the position of the access assembly 50 during horizontal movement, and on the other hand, the distance between the access assembly 50 during the access process and the storage position, the temporary storage position or the transfer vehicle can be adjusted to facilitate access. Thereby, the stability of the access is improved.

[0070] In some embodiments, as shown in FIG. 10, the article access mechanism 200 includes a current collector 205, a sliding contact line 206 is disposed on the horizontal beam, the sliding contact line 206 is electrically connected to the power supply unit, and the current collector 205 is slidably and electrically connected to the sliding contact line 206 to charge the battery 204. Optionally, the sliding contact line 206 is locally disposed in the U-shaped groove of the horizontal beam. Optionally, the cross-section of the horizontal beam is an inverted U-shaped groove, the sliding contact line 206 is disposed in a local area of the inverted U-shaped groove, the contact end of the sliding contact line 206 faces downward, and can be docked with the terminal of the upward current collector 205. When the current collector 205 is not in contact with the sliding contact line 206 in the horizontal beam, the battery 204 supplies power to the motor 203, and when the current collector 205 is in contact with the sliding contact line 206 in the horizontal beam, the battery 204 is charged by the current collector 205.

[0071] In some embodiments, as shown in FIG. 11, the lower end of the vertical track TR2 is higher than the transfer vehicle 300 in the article-loaded state, and the fork mechanism 201 is adjusted so as not to be lower than the transfer vehicle 300 in the article-loaded state, whereby the transfer vehicle 300 in the article-loaded state can basically operate throughout the entire grand 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 lower end of the vertical track TR2, the lower end of the fork mechanism 201 becomes lower than the lower end of the vertical track TR2. As a result, the article at the lower end of the fork mechanism 201 and the plane of the temporary storage position are surely positioned on basically the same plane, and the lower end of the vertical track TR2 is surely higher than the lower end of the fork mechanism 201. On the other hand, since the fork mechanism 201 is configured to have a sinking structure so that the article at the lower end of the fork mechanism 201 and the uppermost layer of the storage position are surely positioned on basically the same plane, the upper end of the vertical track TR2 is higher than the uppermost layer of the storage position. In addition, by using the fork mechanism 201, the article at the lower end of the fork mechanism 201 and each storage position and the temporary storage position can be basically positioned on the same plane, whereby the article can be conveyed between the fork mechanism 201 and the storage position and the temporary storage position.

[0072] In some embodiments, the fork mechanism 201 is docked at a temporary storage position located below the shelf 100 for transporting articles. At this time, although there may be a space for continuous downward movement at the lowest position in the working state of the fork mechanism 201, during the normal operation of the system, theoretically, the fork mechanism 201 can only operate at the above-mentioned position and area. At this time, the lower part of the fork mechanism 201 is higher than the unloaded transfer vehicle 300. On the other hand, the height of the temporary storage position exceeds the height of the transfer vehicle 300 in the article-loaded state. In order to ensure that the transfer vehicle 300 is not obstructed by the vertical track TR2, in this embodiment, the lower end of the vertical track TR2 is higher than the lower end of the temporary storage position, and as shown in FIGS. 4 and 11, the height of the lower end of the vertical track TR2 may be defined to be on the same plane as the plane below the temporary storage mechanism. Thereby, when the height of the temporary storage position is higher than the height of the transfer vehicle 300 in the article-loaded state, the height of the lower end of the vertical track TR2 does not block the transfer vehicle 300, that is, it is possible to stably ensure that the transfer vehicle 300 is not obstructed in both the article-loaded state and the article-unloaded state, regardless of whether the transfer vehicle crosses in a direction intersecting the direction in which the shelf extends or crosses in the direction in which the shelf extends.

[0073] In some embodiments, as shown in FIG. 1, the storage logistics system further includes a working area 500, which is a place for sorting articles. At this place, an operator or a robotic arm can wait until the transfer vehicle 300 sorts the articles on the transfer vehicle 300, and the transfer vehicle 300 is configured to transport articles to or from the working area 500.

Those skilled in the art will naturally understand that the above embodiments can be modified and some of the technical features can be equivalently replaced without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
