Description

Technical Field

[0001] This invention relates to the field of automated storage technology, and more particularly to an automated storage system for wheels and brake discs. Background Technology

[0002] In the manufacturing process of wheelsets (composed of key components such as wheels, axles, and brake discs) for railway vehicles (especially high-speed trains and bullet trains), brake discs and wheels are usually stored in automated warehouses with fixtures (such as pallets and cargo frames), which serve as transfer stations.

[0003] Currently, automated storage and retrieval systems (AS / RS) for wheels and brake discs are typically equipped with automated conveyor lines and automated stacker cranes. When a new production order arrives, the automated stacker crane moves the wheel and brake disc to the target storage location, retrieves the wheel and brake disc, and then moves it to the automated conveyor line for delivery to the wheelset assembly line. When new wheels and brake discs arrive, the automated conveyor line transports them to the AS / RS entrance, and then the automated stacker crane transports them to their designated storage location within the AS / RS for storage.

[0004] Currently, stacker cranes typically consist of ground rails, a traveling mechanism, a lifting mechanism, telescopic forks, and a control system. For heavy goods such as wheels and brake discs, the telescopic forks used generally need to have high load-bearing capacity. Forks currently used in high-load scenarios are generally quite large in size, while goods such as wheels and brake discs, although heavy, have a flat, regular shape and generally require more compact storage space. Therefore, traditionally large forks used in high-load scenarios cannot be directly applied.

[0005] Therefore, this application proposes a three-dimensional storage warehouse with wheels and brake discs that combine high load capacity and compact forks. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a three-dimensional storage warehouse for wheels and brake discs. Its structure is characterized by thinness and high load capacity, making it particularly suitable for the storage and retrieval needs of heavy items such as wheels and brake discs with low storage height. At the same time, it can support bidirectional retrieval function with a single Y-axis power and can also perform high-speed retrieval needs. The structure is more reliable, not easy to damage and easy to maintain.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A three-dimensional storage warehouse for wheels and brake discs includes a three-dimensional warehouse and a stacker crane. The stacker crane is located between two rows of three-dimensional warehouses. The three-dimensional warehouse includes multi-level racks, each rack including multiple storage locations. Each storage location is used to store a frame containing wheels and brake discs. The stacker crane includes a traveling mechanism, a lifting mechanism, and telescopic forks connected in sequence. The telescopic forks include:

[0009] A frame is mounted on the lifting mechanism, and the frame matches the shape of the cargo frame;

[0010] A telescopic plate is slidably connected to the bottom of the frame, and a tray is slidably connected to the top of the telescopic plate, forming a carrying space for telescopic forks between the top of the tray and the frame;

[0011] The telescopic plate includes multiple plates that are stacked and slidably connected in sequence on a horizontal plane. Each plate is rotatably connected to a transmission belt. The portion of the transmission belt above the plate is fixed to the plate above it, and the portion of the transmission belt below the plate is fixed to the plate below it.

[0012] It also includes a drive mechanism located at the bottom of the frame, the output end of which is connected to a telescopic plate. When the drive mechanism is running, the telescopic plate extends into or out of the storage position.

[0013] Using this implementation method, the telescopic plate can enter the storage location from below or directly into the storage location, and complete the storage and retrieval actions in conjunction with the lifting mechanism. The structure is characterized by thinness and high load capacity, making it particularly suitable for storage and retrieval needs of heavy items such as wheels and brake discs that are located in low storage locations. At the same time, it can support bidirectional retrieval functions with a single Y-axis power, and can also perform high-speed retrieval needs. The structure is more reliable, less prone to damage, and easy to maintain.

[0014] Preferably, the storage location is a rectangular space, and the bottom two sides of the storage location are provided with support plates for supporting the bottom two sides of the cargo frame. The distance between the two support plates in each storage location is not less than the width of the pallet.

[0015] This implementation method further optimizes the utilization of existing automated warehouses and supports the use of this thin telescopic fork to perform storage and retrieval tasks.

[0016] Preferably, the telescopic plate includes two sub-plates and two transmission belts, the two sub-plates being a primary plate and a secondary plate, the two transmission belts being a primary transmission belt and a secondary transmission belt, and the telescopic plate and the pallet forming a tertiary telescopic plate;

[0017] The first-stage plate is slidably connected to the bottom of the frame, the first-stage transmission belt is rotatably connected to the first-stage plate, the lower part of the first-stage transmission belt is fixedly connected to the frame, and the upper part of the first-stage transmission belt is fixedly connected to the second-stage plate.

[0018] The secondary plate is slidably connected to the primary plate, the secondary transmission belt is rotatably connected to the secondary plate, the lower part of the secondary transmission belt is fixedly connected to the primary plate, and the upper part of the secondary transmission belt is fixedly connected to the tray.

[0019] The tray is slidably connected to the secondary plate.

[0020] Preferably, the primary transmission belt and the secondary transmission belt are at least one of belts and chains, and the lengths of the primary plate, the secondary plate, and the tertiary plate are equal to those of the frame.

[0021] When the telescopic forks are in the retracted state, the primary drive belt is fixed to the middle of the frame bottom below the primary plate, and the middle of the primary drive belt is fixed to the middle of the secondary plate above the primary plate.

[0022] The secondary transmission belt is fixed to the middle of the primary plate below the secondary plate, and the secondary transmission belt is fixed to the middle of the tray above the secondary plate.

[0023] By adopting this implementation method, under the condition of maximizing the utilization rate of the automated storage and retrieval system, the storage and retrieval tasks of the two sides of the automated storage and retrieval system can be performed through the same telescopic fork, and only one power unit is needed when the telescopic plate is extended and retracted, ensuring its availability in flat storage locations, while reducing the overall structural cost.

[0024] Preferably, the bottom of the frame is provided with a base plate, the primary plate is slidably connected to the base plate via a first guide rail, the secondary plate is slidably connected to the primary plate via a second guide rail, and the tray is slidably connected to the secondary plate via a third guide rail. The first guide rail, the second guide rail, and the third guide rail are all two V-shaped grooves. The axial section of the base plate, the primary plate, the secondary plate, and the tray are all U-shaped with the opening facing upwards. The two V-shaped grooves in each guide rail have openings facing each other.

[0025] This implementation method ensures the structural stability and reliable load-bearing capacity of the telescopic forks, and further reduces the thickness of the telescopic plate, which is beneficial for its application in flat storage locations.

[0026] Preferably, an extension plate is provided on one side of the primary plate in the width direction, the primary transmission belt is rotatably connected to the extension plate, and the portion of the primary transmission belt above the primary plate is fixedly connected to the side wall of the secondary plate.

[0027] Preferably, the base plate, the primary plate, and the secondary plate are all detachably connected to a fixing block for fixing the transmission belt, and the fixing block includes at least one of a clamp, a screw, and a buckle.

[0028] Preferably, the portion of the substrate alignment extension plate is provided with an opening for mounting a fixing block. The fixing block located on the substrate includes a U-shaped base, a pad, and a clamping plate. The U-shaped base is threaded into the opening, the clamping plate is threaded into the pad, and the pad is threaded into the U-shaped base.

[0029] This implementation method improves the maintenance efficiency of the telescopic plate.

[0030] Preferably, a rack is fixedly connected to the bottom of the primary plate, and the driving mechanism is a gear motor; a rack is fixedly connected to the bottom of the primary plate, and the driving mechanism is a gear motor; three proximity switches are evenly distributed on the frame along the telescopic direction of the telescopic plate, and three proximity heads are correspondingly provided on the primary plate.

[0031] Preferably, the lifting mechanism includes a column, a lifting chain rotatably connected to the column, and Z-axis guide columns fixedly connected to both sides of the column. The frame is fixedly connected to the lifting chain, and the frame is slidably connected to the Z-axis guide columns via a guide bracket. The guide bracket includes:

[0032] An upright plate, one side of which is fixedly connected to the frame;

[0033] Back panel, two of the back panels are fixedly connected to the side of the upright panel away from the frame;

[0034] The Y-axis guide wheel is rotatably connected to the back plate, and the Y-axis guide wheel clamps the Z-axis guide post from both sides in the X direction of the Z-axis guide post;

[0035] The X-axis guide wheel is rotatably connected to the back plate. The X-axis guide wheel is distributed on two back plates. The two back plates clamp the two Z-axis guide columns from both sides of the column in the Y-axis direction.

[0036] Compared with the prior art, the beneficial effects of this invention are as follows: the telescopic plate can enter the storage space from below or directly into the storage space, and complete the storage and retrieval actions in conjunction with the lifting mechanism. The structure has the characteristics of thinness and high load, which is especially suitable for the storage and retrieval needs of heavy objects such as wheels and brake discs but with low storage space height. At the same time, it can support bidirectional retrieval function with a single Y-axis power, and can also perform high-speed retrieval needs. The structure is more reliable, not easy to be damaged and easy to maintain. Attached Figure Description

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Example 1:

[0060] Please see Figure 1-13 The present invention provides the following technical solution: a three-dimensional storage warehouse for wheels and brake discs, comprising a three-dimensional warehouse 1 and a stacker crane 2, wherein the stacker crane 2 is located between two rows of three-dimensional warehouses 1, the three-dimensional warehouse 1 includes multi-layer racks 11, the racks 11 include multiple storage positions 12, the storage positions 12 are used to store the cargo frames K with wheels and brake discs, the stacker crane 2 includes a traveling mechanism 3, a lifting mechanism 4 and a telescopic fork 5 connected in sequence, the telescopic fork 5 including:

[0061] Frame 51 is mounted on lifting mechanism 4, and the shape of frame 51 matches that of cargo frame K.

[0062] The telescopic plate 52 is slidably connected to the bottom of the frame 51, and the top of the telescopic plate 52 is slidably connected to the tray 55. The top of the tray 55 and the frame 51 form a carrying space 50 for the telescopic forks 5.

[0063] The telescopic plate 52 includes multiple plates 521 that are stacked and slidably connected in sequence on a horizontal plane. Each plate 521 is rotatably connected to a transmission belt 522. The portion of the transmission belt 522 above the plate 521 is fixed to the plate above it, and the portion of the transmission belt 522 below the plate 521 is fixed to the plate below it.

[0064] It also includes a drive mechanism 56 located at the bottom of the frame 51. The output end of the drive mechanism 56 is connected to the telescopic plate 52. When the drive mechanism 56 is running, the telescopic plate 52 extends into or out of the storage position 12.

[0065] Existing methods typically employ multiple chains or belts to bypass the front or rear of intermediate-level panels to achieve multi-stage telescopic movement (as described in Chinese invention patent CN114314435A, but generally only three stages of telescopic movement are used). However, this method not only limits the telescopic panel 52 to unidirectional telescopic movement, preventing storage and retrieval of the cargo frames K on both sides of the automated warehouse 1, but also results in significant cumulative elastic tensile deformation due to the reliance on chain tension to synchronously pull all panels, creating a series-force model. This leads to substantial deformation, especially with multiple layers, where the deformation at the ends is more likely to exceed the material's yield strength, causing loosening and damage. Furthermore, in the confined space of the automated warehouse 1, failure to fully retract the panel poses a risk of collision with the edge of the shelving 11. Moreover, once damaged, each stage of the panel needs to be disassembled, making repairs difficult.

[0066] As an optional implementation of the present invention, during warehousing, the walking mechanism 3 moves to the entrances and exits on both sides of the automated warehouse 1, and the lifting mechanism 4 drives the telescopic fork 5 to the automatic conveyor line aligned with the entrances and exits. The telescopic fork 5 extends, and the automatic conveyor line transports the cargo frame K into the telescopic fork 5. After the telescopic fork 5 retracts, the lifting mechanism 4 and the walking mechanism 3 move the telescopic fork 5 to the target storage location 12. Then, the telescopic fork 5 extends into the storage location 12 and places the cargo frame K in the storage location 12, thereby completing the warehousing (the target storage location 12 is obtained by RFID radio frequency technology or equivalent existing technology that can identify the product information in the cargo frame K. After identification, a suitable storage location 12 in the automated warehouse 1 is automatically assigned to the cargo frame K. This existing technology is not discussed in this technical solution).

[0067] When the goods are being taken out, the traveling mechanism 3 and the lifting mechanism 4 work together to move the telescopic fork 5 to the target storage location 12. The telescopic fork 5 extends into the storage location 12, and the lifting mechanism 4 rises and lifts the goods frame K before retracting it, thus removing the goods frame K from the storage location 12. Then, the lifting mechanism 4 and the traveling mechanism 3 work together to move the goods frame K to the entrance and exit of the automated warehouse 1 and place the goods frame K on the automatic conveyor line. (The target storage location 12 is determined by the control system receiving production signals and matching the inventory information of the automated warehouse 1 according to the order content. This is existing technology and will not be discussed further.)

[0068] In this implementation, for the process of the telescopic rack 11 performing storage and retrieval tasks in the automated warehouse 1, the telescopic plate 52 first extends from the bottom of the frame 51, driving the pallet 55 into the bottom of the target storage location 12 or directly into the target storage location 12 (when storing goods, the pallet 55 directly enters the target storage location 12; when retrieving goods, it enters from below the target storage location 12, which can also be understood as the telescopic plate 52 driving the pallet 55 to extend into the bottom of the target storage location 12 to align with the bottom of the goods frame K). Then, the lifting mechanism 4 rises or falls to complete the lifting or lowering of the goods frame K on the storage location 12. Subsequently, the telescopic plate 52 retracts and returns to the frame 51, completing the retrieval or storage action of the frame.

[0069] Specifically, the telescopic plate 52 is implemented by using multiple plates 521, with a drive belt 522 rotatably mounted on each plate 521. The upper and lower sides of the drive belt 522 are fixedly connected to the plates adjacent to it. This ensures that whenever any plate 521 is displaced, the two adjacent plates 521 will experience relative displacements in opposite directions. This is because the upper and lower sides of the drive belt 522 have opposite displacement directions when it rotates. Therefore, by applying power to any one plate 521 or to the pallet 55, each stage of the entire telescopic plate 52 can be simultaneously extended or shortened without requiring separate power to each stage.

[0070] For the drive mechanism 56, it can be a combination of gear motor 562 and rack 561 (described later), or it can be any other mechanism capable of driving the telescopic plate 52 (especially the lowermost plate B1) to move bidirectionally in the Y-axis direction. This technical solution does not impose further limitations on this. For the lifting mechanism 4 and the traveling mechanism 3, they can adopt the methods in the prior art.

[0071] Of course, by directly driving the telescopic plate 52 to move on the frame 51 through the drive mechanism 56 at the bottom of the frame 51, that is, by directly driving the lowest plate B1 to move on the frame 51 through the drive mechanism 56, the telescopic plate 52 can be extended and retracted in the direction of the drive mechanism 56.

[0072] For example, such as Figure 8 As shown, when the bottom plate B1 slides to one side (positive Y-axis direction) on the frame 51, the primary transmission belt D1 on the bottom plate B1 moves along with the bottom plate B1. Since the frame 51 is fixed to the primary transmission belt D1, it can cause the primary transmission belt D1 to rotate. Then, the intermediate plate B2 adjacent to the bottom plate B1, due to its fixation to the primary transmission belt D1, also slides on the bottom plate B1 along the positive Y-axis direction. The extension and retraction of the other plates 521 are similar.

[0073] With this implementation, the core component of the telescopic fork 5—the telescopic plate 52—is generally thin, resulting in a naturally thin structure and minimal thickness. Furthermore, during operation, only one power unit drives the multi-stage telescopic movement of the entire telescopic fork 5, eliminating the need for a separate power unit for each stage. The power unit—the power drive mechanism 56—is located at the lower part of the frame 51. During storage and retrieval, the frame 51 does not enter the storage location 12; only the telescopic plate 52 and the pallet 55 move the cargo frame K in and out. This design is easily applicable to cargo frames K, storage locations 12, and automated warehouses 1 specifically for flat products such as wheels and brake discs.

[0074] In addition, this storage facility also discloses a dedicated storage location 12 and a storage and retrieval method. As mentioned above, the telescopic plate 52 enters the storage location 12 from below or directly into the storage location 12, and the lifting mechanism 4 is used to lift and retrieve goods. Therefore, the storage location 12 at the warehouse door and the bottom of the storage location 12 should be open and unobstructed. That is, during the process of the telescopic plate 52 entering the storage location 12, the lifting mechanism will not collide with the shelf 11 when it lifts and lowers synchronously. Therefore, the storage location 12 of this solution is significantly different from the traditional automated warehouse 1.

[0075] The advantage of the storage location 12 and the corresponding storage and retrieval method defined in this solution is that it can be completed using only one set of telescopic plates 52 on the horizontal plane. It eliminates the need for two vertical plates on the side to clamp the goods, and it also eliminates the need to hook the goods frame K from the back. Furthermore, it eliminates the need to design a lifting device in each storage location 12, and it eliminates the need to lift the goods frame K first before the telescopic plates 52 can be inserted into the bottom of the goods frame K to support it.

[0076] In addition, since the telescopic plate 52 is fixed in the positive and negative directions of the Y-axis, functionally, this telescopic fork 5 can access both the positive and negative Y-axis cargo frames K. Furthermore, it is equipped with a frame 51 to prevent the cargo frames K from falling due to inertial offset in the Z and X-axis directions during the movement of the stacker crane 2. This allows the stacker crane 2 to operate at a higher speed when storing and retrieving goods, thereby improving the efficiency of inbound and outbound operations.

[0077] Regarding the load-bearing capacity of the telescopic forks 5 in this solution, since each level plate is equipped with its own drive belt 522, and each drive belt 522 evenly distributes the total load, the elastic tensile deformation of each drive belt 522 is reduced, making it less prone to damage. This not only improves load-bearing capacity but also makes it easier to withstand the impact of damaged loads. This provides better safety and reliability in the field of automated warehouses with wheels and brake discs that require high-load and high-speed storage and retrieval. It also makes it easier to ensure the correct placement distance of the pallet 55 during storage and retrieval, avoiding situations where the center of gravity shifts or the pallet is not placed correctly. Furthermore, even if damaged, maintenance is easy; only the damaged level needs to be disassembled.

[0078] With the above structure, the telescopic plate 52 can enter the storage location 12 from below or directly into the storage location 12, and complete the storage and retrieval actions in conjunction with the lifting mechanism 4. The structure has the characteristics of thinness and high load, which is especially suitable for the storage and retrieval needs of heavy objects such as wheels and brake discs but with low storage location 12 height. At the same time, it can support bidirectional retrieval function with a single Y-axis power, and can also perform high-speed retrieval needs. The structure has stronger reliability, is not easy to damage and is easy to maintain.

[0079] Furthermore, for thin products such as wheels and brake discs that are flat in structure but have high usage requirements, this technical solution also improves the existing automated storage and retrieval system 1.

[0080] For example, such as Figure 1-4 As shown, storage location 12 is a rectangular space. Support plates 121 for supporting the bottom sides of the cargo frame K are provided on both sides of the bottom of storage location 12. The distance between the two support plates 121 in each storage location 12 is not less than the width of the pallet 55.

[0081] As an optional implementation of this invention, the wheel, also known as a wheel disc, is flat like a brake disc. Currently, they are generally placed in a rectangular plastic frame (i.e., a cargo frame K). Therefore, in order to increase the number of storage locations 12 in the automated warehouse 1 within the same volume, the storage locations 12 are designed as relatively flat rectangular shapes. In fact, each row of automated warehouse 1 consists of multiple horizontal bars 111 (X-axis) and multiple columns of uprights 112 (Z-axis, with two uprights in each column of uprights 112) forming the basic support. Each layer of horizontal bars 111 connects to each column of uprights 112 on the exterior of the automated warehouse 1, thereby dividing the basic support into multiple layers of shelves 11. Then, two horizontally aligned vertical beams (Y-axis) connect the uprights 112 on one side of the warehouse to the connection points between the uprights 112 and the horizontal bars 111 on the warehouse surface, constructing multiple grids and thus dividing the storage locations 12. Support plates 121 are installed on the vertical beams. The support plates 121 can be corner plates to improve structural strength and load-bearing capacity. In this way, the front end of each storage location 12 is unobstructed. After the telescopic plate 52 enters any storage location 12, it can smoothly shuttle through each storage location 12 along the vertical direction of that storage location 12 (when there is no cargo frame K, it passes between the two support plates 121 when crossing storage locations 12). This ensures the aforementioned storage and retrieval method - the telescopic plate 52 directly enters the target storage location 12 or extends from below the target storage location 12, and then cooperates with the lifting mechanism 4 to complete the storage and retrieval action of raising or lowering the cargo frame K.

[0082] The advantage of this implementation method is that, within the same spatial volume, more storage locations 12 can be designed. The height of each storage location 12 is approximately the overall thickness of the telescopic plate 52 + the height of the cargo frame K + the lifting margin of the lifting mechanism 4 (approximately 5mm margin is sufficient), maximizing the space utilization of the automated warehouse 1 while ensuring that the telescopic forks 5 can perform storage and retrieval functions. Of course, ensuring the structural strength of the automated warehouse 1 itself depends on the materials and specifications of the horizontal bars 111, vertical bars 113, and uprights 112 used, which can be calculated based on actual construction requirements. This technical solution will not elaborate on this further.

[0083] The above structure further optimizes the utilization of the existing automated warehouse 1 and supports the thin telescopic forks 5 in performing storage and retrieval tasks.

[0084] Furthermore, multi-stage telescopic systems have demonstrated in various fields that, under the same elongation conditions, when the number of stages exceeds a certain limit, load-bearing capacity and accuracy will decrease. Therefore, it is necessary to further limit the number of stages of the telescopic plate 52.

[0085] For example, such as Figure 9-12 As shown, the telescopic plate 52 includes two sub-plates 521 and two transmission belts 522. The two sub-plates 521 are respectively a first-level plate 5211 and a second-level plate 5212, and the two transmission belts 522 are respectively a first-level transmission belt 5221 and a second-level transmission belt 5222. The telescopic plate 52 and the pallet 55 form a three-level telescopic plate 520.

[0086] The first-stage plate 5211 is slidably connected to the bottom of the frame 51, the first-stage transmission belt 5221 is rotatably connected to the first-stage plate 5211, the lower part of the first-stage transmission belt 5221 is fixedly connected to the frame 51, and the upper part of the first-stage transmission belt 5221 is fixedly connected to the second-stage plate 5212.

[0087] The secondary plate 5212 is slidably connected to the primary plate 5211, and the secondary transmission belt 5222 is rotatably connected to the secondary plate 5212. The lower part of the secondary transmission belt 5222 is fixedly connected to the primary plate 5211, and the upper part of the secondary transmission belt 5222 is fixedly connected to the tray 55.

[0088] The tray 55 is slidably connected to the secondary plate 5212.

[0089] As an optional implementation of the present invention, considering that the actual storage and retrieval (Y-axis) travel of the automated warehouse 1 is not too large, and that the existing multi-stage telescopic plate 52 with high load performance requirements is generally a three-stage telescopic plate 520, this technical solution also limits the entire telescopic fork 5 to a three-stage telescopic structure. In addition, to ensure the accurate entry and exit of the cargo frame K, the maximum width of the telescopic plate 52 and the pallet 55 is less than the distance between the two support plates 121, and when the telescopic plate 52 is in the retracted state, the geometric center and center of gravity of the pallet 55 should coincide with the geometric center of the frame 51 in the vertical direction. Those skilled in the art can also make anti-slip designs on the top of the pallet 55, such as anti-slip scales, damping pads, etc., to avoid the center of gravity shift during the transportation of the cargo frame K and thus the inability to complete the storage and retrieval task.

[0090] Furthermore, existing bidirectional storage and stacking solutions do not involve multi-level telescopic technology. They generally use multiple power units (two), each equipped with a separate fork, or bidirectional cylinders, or a reversing function for a single multi-level telescopic plate 52. However, all of these implementation methods require multiple power units, which either increases the volume and is not suitable for this flat storage location 12, or increases the structural cost, or results in insufficient storage and retrieval efficiency due to the multiple execution steps.

[0091] For example, such as Figure 10-12 As shown, the primary transmission belt 5221 and the secondary transmission belt 5222 are at least one of belts and chains, and the lengths of the primary plate 5211, the secondary plate 5212, the tertiary plate and the frame 51 are equal.

[0092] When the telescopic fork 5 is in the retracted state, the first-stage drive belt 5221 is fixed to the middle of the bottom of the frame 51 below the first-stage plate 5211, and the middle of the first-stage drive belt 5221 is fixed to the middle of the second-stage plate 5212 above the first-stage plate 5211.

[0093] The secondary drive belt 5222 is fixed to the middle of the primary plate 5211 below the secondary plate 5212, and the secondary drive belt 5222 is fixed to the middle of the pallet 55 above the secondary plate 5212.

[0094] As an optional implementation of the present invention, the telescopic fork 5 described above can extend and retract bidirectionally in the Y-axis direction. That is, the storage and retrieval tasks of the automated storage and retrieval system 1 on both sides of the stacker crane 2 can be met by a single multi-stage telescopic plate 52, without the need for steering or additional power components. The power components and the fixing points of each transmission belt 522 and adjacent plates are designed in the middle position to ensure that the maximum extension stroke of the telescopic fork 5 to the automated storage and retrieval system 1 on both sides is consistent. At the same time, the relative displacement of the first-stage plate 5211 relative to the base plate 511, the relative displacement of the second-stage plate 5212 relative to the first-stage plate 5211, and the relative displacement of the pallet 55 relative to the second-stage plate 5212 are each divided into 1 / 3 of the total extension length. Therefore, when the first-stage plate 5211 moves to 1 / 3 of the designed total extension length of the telescopic plate 52, the entire telescopic plate 52 is fully extended, and the pallet 55 is fully inserted into the storage position 12.

[0095] In this implementation, it is also revealed that the lengths of the frame 51, pallet 55, and each level of partition 521 are roughly equivalent to the length of the cargo frame K. Under the requirement of a compact structure for the automated warehouse 1, the width of the automated warehouse 1 (i.e., the length of the vertical beam) and the spacing between the two automated warehouses 1 are roughly equivalent.

[0096] With the above structure, under the condition of maximizing the utilization rate of the automated storage and retrieval system 1, the storage and retrieval tasks of the two sides of the automated storage and retrieval system 1 can be performed through the same telescopic fork 5, and only one power unit is needed when the telescopic plate 52 is extended and retracted, ensuring its availability in the flat storage space 12, while reducing the overall structural cost.

[0097] Furthermore, the storage and retrieval tasks are performed by the multi-stage telescopic plate 52 located in the horizontal plane supporting the cargo frame K. When the telescopic forks 5 are at their maximum extension stroke, the pallet 55 needs to have sufficient load.

[0098] For example, such as Figure 10-12 As shown, the bottom of the frame 51 is provided with a base plate 511. The first plate 5211 is slidably connected to the base plate 511 via the first guide rail 531. The second plate 5212 is slidably connected to the first plate 5211 via the second guide rail 532. The tray 55 is slidably connected to the second plate 5212 via the third guide rail 533. The first guide rail 531, the second guide rail 532 and the third guide rail 533 are all two V-shaped grooves. The axial section of the base plate 511, the first plate 5211, the second plate 5212 and the tray 55 are all U-shaped with the opening 5111 facing upward. The two V-shaped grooves in each guide rail have openings 5111 facing each other.

[0099] As an optional implementation of this invention, a V-shaped chute is a commonly used guide rail. By defining each stage plate 521 as a U-shaped structure, with each guide rail located on both side walls of the U-shape and the openings 5111 facing opposite directions, each stage plate 521 and the tray 55 are constrained in both the Z and X axes. This ensures that the three-stage telescopic plate 520, composed of each stage plate 521 and the tray 55, has strong structural stability and is unlikely to detach from each other, thus possessing reliable load-bearing capacity. Of course, this design also further reduces the overall thickness of the three-stage telescopic plate 520, making it more suitable for performing storage and retrieval tasks in the flat storage location 12.

[0100] It is worth noting that guide rails can also use U-shaped or H-shaped grooves. Their principle is the same as that of V-shaped grooves, and they can be regarded as equivalent replacements for V-shaped grooves.

[0101] The above structure ensures the structural stability and load-bearing capacity of the telescopic fork 5, and further reduces the thickness of the telescopic plate 52, which is beneficial for its application in the flat storage space 12.

[0102] Furthermore, an extension plate 52111 is provided on one side of the width direction of the primary plate 5211, and the primary transmission belt 5221 is rotatably connected to the extension plate 52111. The portion of the primary transmission belt 5221 located above the primary plate 5211 is fixedly connected to the side wall of the secondary plate 5212.

[0103] As an optional implementation of the present invention, the first-level transmission belt 5221 is installed by extending the plate 52111. Compared with the method of installing the transmission belt 522 in the U-shaped groove of the first-level plate 5211, this can effectively avoid the installation space of the second-level transmission belt 5222, without increasing the distance between the first-level plate 5211 and the second-level plate 5212, and ensure that the overall thickness of the telescopic plate 52 is at a low parameter.

[0104] Furthermore, such as Figure 9-12 As shown, the base plate 511, the primary plate 5211, and the secondary plate 5212 are all detachably connected with fixing blocks 54 for fixing the transmission belt 522. The fixing blocks 54 include at least one of the following: clamping plate 543, screw, and buckle.

[0105] As an optional implementation of the present invention, the detachable connection method facilitates quick maintenance and replacement of the transmission belt 522. The transmission belt 522 can be either a belt or a chain; this technical solution does not limit either option.

[0106] like Figure 12As shown, both the base plate 511 and the primary plate 5211 are provided with openings 5111 for mounting the fixing block 54. The fixing block 54 located on the base plate 511 includes a U-shaped base 541, a pad 542 and a clamping plate 543. The U-shaped base 541 is threaded into the opening 5111, the clamping plate 543 is threaded into the pad 542, and the pad 542 is threaded into the U-shaped base 541. The opening 5111 on the base plate 511 is located on the extension plate 52111.

[0107] As an optional implementation of this invention, the clamping plate 543, as the name suggests, consists of two plates that can clamp the transmission belt 522. Alternatively, a single plate can be used in conjunction with the pad 542 to fix the transmission belt 522. This method does not damage the structure of the transmission belt 522 itself, ensuring its tensile strength. Furthermore, the design of the U-shaped base 541 ensures that the overall thickness of the fixing block 54 is not too large. The threaded connection method satisfies both maintainability and connection strength. Of course, when the transmission belt 522 exhibits slight plastic deformation, it is not necessary to directly replace the transmission belt 522. Instead, by replacing the thinner pad 542, the tension of the installed transmission belt 522 can be achieved. This eliminates the need to completely remove the transmission belt 522. Replacing a single transmission belt 522 directly involves disassembling at least three plates. Therefore, replacing the pad 542 provides better maintenance efficiency.

[0108] The above structure improves the maintenance efficiency of the telescopic plate 52.

[0109] like Figure 9-11 As shown, a rack 561 is fixedly connected to the bottom of the primary plate 5211, and the drive mechanism 56 is a gear motor 562; a rack 561 is fixedly connected to the bottom of the primary plate 5211, and the drive mechanism 56 is a gear motor 562; three proximity switches 57 are evenly distributed on the frame 51 along the telescopic direction of the telescopic plate 52, and three proximity heads 58 are correspondingly provided on the primary plate 5211.

[0110] As an optional implementation of the present invention, the use of rack 561 and gear motor 562 has the advantage that their overall size is not large, and the motor configuration is conducive to servo or stepper control, improving the precise control of the extension stroke. The advantage of designing three proximity switches 57 and arranging them evenly is that it facilitates the simultaneous detection of the maximum displacement in the Y- and Y+ directions.

[0111] Specifically, when the first-stage plate 5211 moves along the Y+ direction, the proximity head 58 near the Y- direction aligns with the proximity switch 57 in the middle, which triggers the proximity switch 57 and sends a positioning command to the control system, controlling the gear motor 562 to stop rotating and controlling the lifting mechanism 4 to run.

[0112] Example 2:

[0113] Furthermore, considering that the drive belt 522, whether using a chain or a belt, is subject to tensile deformation, this will lead to inaccurate positioning displacement of adjacent plates. In severe cases, due to the excessive looseness of the drive belt 522, the pallet 55 may not accurately reach the appropriate position at the bottom of the cargo frame K, causing the center of gravity to move further away from the telescopic fork 5 during storage and retrieval, thus accelerating the aging rate of the guide rail and drive belt 522. In extreme cases, if the pallet 55 fails to reach the correct position, the cargo frame K may tilt when lifted by the pallet 55, causing the wheels and brake discs inside the warehouse to fall off, affecting the use of the entire storage warehouse. Alternatively, the pallet 55 and / or the cargo frame K may not be fully inserted into the carrying space of the frame 51, or the pallet 55 / cargo frame K may not be fully removed from the storage position 12, or the pallet 55 may not be able to fully deliver the cargo frame K into the storage position 12. All of these situations can easily lead to collisions during the operation of the stacker crane 2. Furthermore, after the transmission belt 522 is stretched and deformed, the center of gravity of the cargo frame K moves further away from the frame 51, which will exacerbate the wear of the guide rail. This is especially noticeable in scenarios where the load is heavy (some can weigh several tons) such as wheels and brake discs. In particular, the upper wall of the guide rail will be worn down. In severe cases, this will cause the pallet 55 to tilt, making it impossible for the pallet 55 to enter the storage space 12 with a low margin (such as the aforementioned lifting margin of only 5mm, which is expressed as the distance between the top of the cargo frame K and the bottom of the upper cargo frame K when the lower storage space 12 is filled with cargo frame K). As a result, the task of storing and retrieving goods cannot be performed.

[0114] For example, such as Figure 11 As shown, the pallet 55 is also equipped with cameras 6 at both ends of the Y-axis direction for detecting the distance between the edge of the pallet 55 and the inner side of the cargo frame K.

[0115] As an optional implementation of the present invention:

[0116] When pallet 55 is inserted into storage location 12, an image of the bottom of the cargo frame K is captured;

[0117] After binarizing the bottom image of the cargo frame K, the first standard distance image is called and compared with the processed bottom image of the cargo frame K to calculate the vertical and horizontal distances from the edge of the current pallet 55 to the bottom edge of the cargo frame K.

[0118] The air transport tilt angle of pallet 55 is further calculated based on the vertical and horizontal distances.

[0119] Determine whether the extension distance and tilt angle of pallet 55 meet the safety threshold and maintenance threshold;

[0120] When the maintenance threshold is reached, a maintenance alarm is triggered; when the safety threshold is reached, an alarm is triggered immediately and the currently executing access task is stopped.

[0121] In this implementation, the first standard distance image is the calibration image, which is an image acquired before the conveyor belt 522 and guide rail have performed any storage or retrieval tasks. It serves as a reference for calculating the distance from the edge of the cargo frame K to the end of the pallet 55 and is stored in the system beforehand. The camera 6 can be a common image detection camera. Since there may be no light in this storage area, a light fixture can be installed at the end of the pallet 55 to illuminate the camera 6. The communication method between the camera 6 and the control system can be wireless with battery or wired. Because image acquisition technology is already maturely used in edge detection in industry, this technical solution will not elaborate on the specific image processing methods of these existing technologies. Safety thresholds and maintenance thresholds are set in advance; however, the specific threshold range is not limited in this technical solution.

[0122] Preferably, the maintenance threshold has an extension distance of 2-10mm and a tilt angle of 0.1-0.5°, while the safety threshold has an extension distance of greater than or equal to 10mm and a tilt angle of greater than or equal to 0.5°.

[0123] In this embodiment, after pallet 55 enters storage location 12, it receives the arrival signal from proximity switch 57, and then acquires an image of the bottom edge of the cargo frame K. By comparing it with a standard image as a reference, it can determine the tilt angle of pallet 55 in its empty state (i.e., when performing a picking task) and the center of gravity position of cargo frame K when placed on pallet 55. This allows for further determination of the stretching degree of the transmission belt 522 and the wear degree of the guide rail, thus determining whether the current picking task can continue. If it can, it continues; if it cannot, it determines whether maintenance is needed. If maintenance is not possible, the current task is stopped directly. This avoids the problem of storage and retrieval tasks failing due to increased guide rail wear or excessive looseness of the transmission belt 522. It also prompts the operator to maintain the telescopic fork 5 when a certain degree of wear or looseness is reached, thereby extending the service life of the telescopic fork 5.

[0124] Furthermore, there are cases where pallet 55 cannot enter storage location 12 due to excessive tilt angle (especially during storage). Therefore, the tilt angle of pallet 55 also needs to be checked before it enters storage location 12.

[0125] For example, before pallet 55 enters storage location 12, the following steps are also included:

[0126] Obtain the image of storage location 12 and perform binarization on the image;

[0127] The second standard distance image is retrieved and compared with the processed image of storage location 12 to calculate the vertical and horizontal distances from the current pallet 55 to storage location 12.

[0128] The load tilt angle of pallet 55 is further calculated based on the vertical and horizontal distances.

[0129] Determine whether the tilt angle of pallet 55 exceeds the safety threshold and maintenance threshold;

[0130] When the maintenance threshold is reached, a maintenance alarm is triggered; when the safety threshold is reached, an alarm is triggered immediately and the currently executing access task is stopped.

[0131] Using this implementation, before pallet 55 enters storage location 12, it receives the arrival signal from lifting mechanism 4, and then acquires an image of storage location 12 (which can be the end of upright post 112 or vertical post 113 at the storage opening, or the storage opening formed by support plate 121, upright post 112, and the end of vertical post 113). By comparing with a standard image as a reference, it can determine the tilt angle of pallet 55 under load (i.e., when performing a storage task) and the center of gravity position of the cargo frame K when placed on pallet 55. This allows for further determination of the tension of the transmission belt 522 and the wear of the guide rail, thus determining whether pallet 55 can still enter storage location 12, and further determining whether the retrieval task can continue. If it can, it continues; if it cannot, it determines whether maintenance is needed; if maintenance is not needed, the current task is stopped directly. This avoids the problem of storage and retrieval tasks failing due to increased guide rail wear or excessive looseness of the transmission belt 522, and also prompts operators to maintain the telescopic forks 5 when a certain degree of wear or looseness is reached, thus extending the service life of the telescopic forks 5.

[0132] Example 3:

[0133] like Figure 13-14 As shown, based on Embodiment 1, the connection between the telescopic fork 5 and the lifting mechanism 4 is further defined: the lifting mechanism 4 includes a column 41, a lifting chain 42 rotatably connected to the column 41, and a Z-axis guide column 43 fixedly connected to both sides of the column 41. The frame 51 is fixedly connected to the lifting chain 42, and the frame 51 is slidably connected to the Z-axis guide column 43 through a guide frame 59. The guide frame 59 includes:

[0134] Upright plate 591, one side of which is fixedly connected to frame 51;

[0135] Back panel 592, two back panels 592 are fixedly connected to the side of the upright panel 591 away from the frame 51;

[0136] Y-axis guide wheel 593 is rotatably connected to back plate 592. Y-axis guide wheel 593 clamps Z-axis guide post 43 from both sides of Z-axis guide post 43 in the X direction.

[0137] X-axis guide wheel 594 is rotatably connected to back plate 592. X-axis guide wheels 594 are distributed on two back plates 592 respectively. The two back plates 592 clamp two Z-axis guide columns 43 from both sides of column 41 in the Y-axis direction. Each back plate 592 is provided with two vertically aligned X-axis guide wheels 594.

[0138] As an optional implementation of the present invention, during the storage and retrieval process, when the telescopic plate 52 extends into the storage position 12, the center of gravity of the entire telescopic fork 5 shifts, causing a pulling force on the lifting mechanism 4, especially when performing storage and retrieval tasks at higher storage positions 12, where the force on the lifting mechanism 4 is more pronounced. The cooperation between the X-axis guide wheel 594 and the column 41 not only makes the lifting and lowering movement of the telescopic fork 5 on the column 41 smoother but also strengthens the connection stability between the telescopic fork 5 and the lifting mechanism 4. When the traveling mechanism 3 moves within the automated warehouse 1, the Y-axis guide wheel 593 enables the telescopic fork 5 to better resist instantaneous impact forces in the X-axis direction, further improving the connection stability between the telescopic fork 5 and the lifting mechanism 4.

[0139] The working principle and usage process of this invention are as follows: During warehousing, the traveling mechanism 3 moves to the entrances / exits on both sides of the automated warehouse 1. The lifting mechanism 4 drives the telescopic fork 5 to the automatic conveyor line aligned with the entrance / exit. The telescopic fork 5 extends, and the automatic conveyor line transports the cargo frame K into the telescopic fork 5. After the telescopic fork 5 retracts, the lifting mechanism 4 and the traveling mechanism 3 move the telescopic fork 5 to the target storage location 12. Subsequently, the telescopic fork 5 extends into the storage location 12 and places the cargo frame K in the storage location 12, thus completing the warehousing process. During warehousing, the traveling mechanism 3 and the lifting mechanism 4 work together to move the telescopic fork 5 to the target storage location 12. The telescopic fork 5 extends into the storage location 12, and the lifting mechanism 4 rises to lift the cargo frame K and then retracts, thus removing the cargo frame K from the storage location 12. Subsequently, the lifting mechanism 4 and the traveling mechanism 3 work together to drive the cargo frame K to the entrance / exit of the automated warehouse 1 and place the cargo frame K on the automatic conveyor line.

[0140] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
