Description

Technical Field

[0001] The present invention relates to the technical field of stereoscopic storage, and in particular to a stereoscopic storage for wheels and brake discs. Background Art

[0002] During the manufacturing process of wheelsets (consisting of key components such as wheels, axles, and brake discs) for railway vehicles (especially high-speed trains and EMUs), brake discs and wheels are usually stored in a stereoscopic warehouse in a matching manner using jigs (such as pallets, cargo frames, etc.), and the stereoscopic warehouse serves as a transfer station.

[0003] Currently, wheel and brake disc warehouses are typically equipped with automated conveyor lines and automated stackers. When a new production order arrives, the automated stacker moves the wheels to the target warehouse location, retrieves the desired wheels and brake discs, and then moves them to the automated conveyor line, where they are delivered to the wheelset assembly line. When new wheels and brake discs arrive, the automated conveyor line transports them to the warehouse entrance, where the automated stacker then moves them to a warehouse location for storage.

[0004] Currently, stackers typically consist of a floor rail, a travel mechanism, a lifting mechanism, a telescopic fork, and a control system. For heavy cargo like wheels and brake discs, the telescopic forks used generally require high load capacity. Forks currently used in high-load scenarios are generally large in size. While heavy, cargo like wheels and brake discs are flat and regular in shape, requiring relatively compact storage locations. Therefore, the larger forks typically used in high-load scenarios cannot be directly used.

[0005] To this end, the present application proposes a three-dimensional storage warehouse for wheels and brake discs with a fork that has both high load capacity and compactness. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a three-dimensional storage warehouse for wheels and brake discs. The warehouse has the characteristics of thin thickness and high load, which is particularly suitable for the storage and retrieval needs of wheels and brake discs that are heavy but have low storage height. At the same time, it can support two-way picking functions with a single Y-axis power, and can also meet high-speed picking requirements. The structure is more reliable, not easy to damage and easy to maintain.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: A three-dimensional storage warehouse for wheels and brake discs, comprising a three-dimensional warehouse and a stacker, wherein the stacker is arranged between two rows of three-dimensional warehouses, the three-dimensional warehouse comprises multi-layer shelves, the shelves comprise multiple storage locations, and the storage locations are used to store cargo frames with wheels and brake discs, the stacker comprises a walking mechanism, a lifting mechanism, and a telescopic fork connected in sequence, and the telescopic fork comprises: a frame, provided on the lifting mechanism, the frame matching the shape of the cargo frame; A telescopic plate is slidably connected to the bottom of the frame, and a pallet is slidably connected to the top of the telescopic plate, and a carrying space for the telescopic fork is formed between the top of the pallet and the frame; The telescopic plate includes a plurality of split plates stacked in sequence on a horizontal plane and slidably connected, each split plate being rotatably connected to a transmission belt, the portion of the transmission belt located above the split plate being fixed to the upper split plate, and the portion of the transmission belt located below the split plate being fixed to the lower split plate; It also includes a driving mechanism arranged at the bottom of the frame, wherein the output end of the driving mechanism is connected to the telescopic plate, and when the driving mechanism is running, the telescopic plate extends into or out of the storage position.

[0008] With this implementation, the telescopic plate can enter the storage location from below or directly into the storage location, and cooperate with the lifting mechanism to complete the storage and retrieval actions. The structure has the characteristics of thin thickness and high load, which is particularly suitable for the storage and retrieval needs of heavy wheels and brake discs but low storage height.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: See also Figure 1-13The 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 2. The stacker 2 is arranged between two rows of three-dimensional warehouses 1. The three-dimensional warehouse 1 includes multi-layer shelves 11. The shelves 11 include multiple storage locations 12. The storage locations 12 are used to store cargo boxes K with wheels and brake discs. The stacker 2 includes a walking mechanism 3, a lifting mechanism 4, and a telescopic fork 5 connected in sequence. The telescopic fork 5 includes: Frame 51, provided on the lifting mechanism 4, frame 51 matches the shape of the cargo box K; The telescopic plate 52 is slidably connected to the bottom of the frame 51. The top of the telescopic plate 52 is slidably connected to the pallet 55. The carrying space 50 of the telescopic fork 5 is formed between the top of the pallet 55 and the frame 51. The telescopic plate 52 includes a plurality of sub-plates 521 stacked in sequence on a horizontal plane and slidably connected. A transmission belt 522 is rotatably connected to each sub-plate 521. The portion of the transmission belt 522 located above the sub-plate 521 is fixed to the upper sub-plate 521, and the portion of the transmission belt 522 located below the sub-plate 521 is fixed to the lower sub-plate 521. The frame 51 further includes a driving mechanism 56 disposed at the bottom thereof. An output end of the driving mechanism 56 is connected to the telescopic plate 52 . When the driving mechanism 56 is in operation, the telescopic plate 52 extends into or out of the storage location 12 .

[0027] Conventional methods typically employ multiple chains or belts that wrap around the front or rear ends of the intermediate panels to achieve multi-stage retraction (e.g., Chinese invention patent publication number CN114314435A, which generally implements three-stage retraction). However, this approach not only limits the retractable panel 52 to one-way retraction, preventing access to the cargo racks K on both sides of the three-dimensional warehouse 1. Furthermore, the single-chain approach relies on chain tension to synchronously pull all panels, creating a series load-bearing model. This results in significant cumulative elastic tensile deformation during use, especially when multiple levels are stacked. The deformation at the end is more likely to exceed the material's yield point, leading to slack and damage, and the required accuracy is insufficient. In a confined space like a three-dimensional warehouse 1, failure to fully retract creates the risk of collision with the edge of the shelf 11. Furthermore, damage requires disassembly of each panel level, making repair difficult.

[0028] As an optional implementation of the present invention, when entering the warehouse, the walking mechanism 3 moves to the entrances and exits on both sides of the three-dimensional warehouse 1, and the lifting mechanism 4 drives the telescopic forks 5 to the automatic conveyor line aligned with the entrance and exit. The telescopic forks 5 are extended, and the automatic conveyor line conveys the cargo box K to the telescopic forks 5. After the telescopic forks 5 are retracted, the lifting mechanism 4 and the walking mechanism 3 move the telescopic forks 5 to the target storage location 12, and then the telescopic forks 5 are extended into the storage location 12 to place the cargo box K in the storage location 12, thereby completing the storage (the acquisition of the target storage location 12 is achieved by RFID radio frequency technology or an equivalent existing technology that can identify the product information in the cargo box K. After identification, the cargo box K is automatically allocated to the appropriate storage location 12 in the three-dimensional warehouse 1. This existing technology is not discussed in this technical solution); When leaving the warehouse, the walking mechanism 3 and the lifting mechanism 4 are linked to drive the telescopic fork 5 to move to the target storage location 12, and the telescopic fork 5 extends into the storage location 12. The lifting mechanism 4 rises and lifts the cargo frame K and then retracts to take the cargo frame K out of the storage location 12. Then the lifting mechanism 4 and the walking mechanism 3 are linked to drive the cargo frame K to the entrance and exit of the three-dimensional warehouse 1, and place the cargo frame K on the automatic conveyor line (the target storage location 12 is matched to the target storage location 12 by the control system receiving the production signal and matching the inventory information of the three-dimensional warehouse 1 according to the order content. This is the existing technology and will not be discussed in detail).

[0029] In this implementation, for the process of the telescopic shelf 11 performing storage and retrieval tasks in the three-dimensional warehouse 1, the telescopic plate 52 first extends from the bottom of the frame 51, driving the pallet 55 to enter the bottom of the target storage location 12 or directly enter the target storage location 12 (when storing goods, the pallet 55 directly enters the target storage location 12; when picking up goods, it enters from under the target storage location 12, which can also be understood as the telescopic plate 52 driving the pallet 55 to extend under the target storage location 12 and align with the bottom of the cargo frame K), and then the lifting mechanism 4 rises or falls to complete the lifting or lowering of the cargo frame K on the storage location 12, and then the telescopic plate 52 retracts and returns to the frame 51 to complete the picking or storing action of the plastic frame.

[0030] The telescopic plate 52 is specifically implemented using multiple sub-plates 521, each of which is rotatably mounted with a transmission belt 522. The upper and lower sides of the transmission belt 522 are fixedly connected to the adjacent plates. This ensures that whenever a sub-plate 521 is displaced, the two adjacent sub-plates 521 above and below it will also experience relative displacement in opposite directions. This is due to the opposite displacement directions of the upper and lower sides of the transmission belt 522 when it rotates. Therefore, simply applying power to any sub-plate 521 or the tray 55 can cause each stage of the telescopic plate 52 to extend or contract simultaneously, without the need to apply power to each stage individually.

[0031] The drive mechanism 56 can be a combination of a gear motor 562 and a rack 561, described later, or any other mechanism capable of driving the telescopic plate 52 (particularly the lowermost plate B1) to move bidirectionally in the Y-axis direction. This technical solution does not impose any further limitations on this mechanism. The lifting mechanism 4 and the travel mechanism 3 can be implemented using conventional methods.

[0032] Of course, we directly drive the telescopic plate 52 to move on the frame 51 through the driving mechanism 56 at the bottom of the frame 51, that is, the driving mechanism 56 directly drives the lowermost plate B1 to move on the frame 51, so that the telescopic plate 52 as a whole can be extended and retracted in the power direction of the driving mechanism 56.

[0033] For example, Figure 8 As shown, when the lowermost panel B1 slides to one side (in the positive direction of the Y-axis) on the frame 51, the primary transmission belt D1 on the lowermost panel B1 moves along with the lowermost panel 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 panel B2 adjacent to the lowermost panel B1, due to its fixation with the primary transmission belt D1, causes the intermediate panel B2 to also slide on the lowermost panel B1 in the positive direction of the Y-axis. The extension and retraction of the remaining panels 521 are similar.

[0034] With this implementation, the core component of the telescopic fork 5—the telescopic plate 52—is thin and therefore not very thick. Furthermore, during operation, a single power component drives the multi-stage telescopic movement of the telescopic fork 5, eliminating the need for a separate power component for each stage. Furthermore, the power component—the power drive mechanism 56—is located below the frame 51. During storage and retrieval, the frame 51 does not enter the storage location 12; only the telescopic plate 52 and pallet 55 drive the cargo frame K in and out. This makes it easily applicable to cargo frames K, storage locations 12, and the three-dimensional warehouse 1, which are specifically designed for flat products such as wheels and brake discs.

[0035] In addition, this storage warehouse also discloses a special storage location 12 and a method of storing and retrieving goods. As mentioned above, the storage location 12 is entered from below or directly into the telescopic plate 52 in the storage location 12, and the lifting mechanism 4 is lifted and lowered to realize storage and retrieval. Therefore, the storage location 12 is located at the warehouse door and the bottom of the storage location 12 should be hollow and unobstructed. That is, when the telescopic plate 52 enters the storage location 12, the elevator will not collide with the shelf 11 when it is lifted and lowered synchronously. Therefore, the storage location 12 of this scheme is obviously different from the traditional three-dimensional warehouse 1.

[0036] The advantage of the storage location 12 and the corresponding storage and retrieval method defined in this solution is that it can be completed with only a set of telescopic plates 52 on the horizontal plane. There is no need for two vertical plates on the side to clamp the cargo box K, nor is there any need to hook the cargo box K from the back of the cargo box K. There is no need to design a lifting device in each storage location 12, and there is no need to lift the cargo box K before the telescopic plates 52 can extend into the bottom of the cargo box K to support the cargo box K.

[0037] In addition, since the telescopic plate 52 is fixed in the positive and negative directions of the Y-axis, at the functional level, the telescopic fork 5 can store and retrieve cargo frames K in the positive direction of the Y-axis, as well as in the negative direction of the Y-axis. It is also equipped with a frame 51 to prevent the cargo frames K from falling due to inertial deviation in the Z-axis and X-axis directions during the movement of the stacker 2, so that the stacker 2 can operate at a higher speed for storing and retrieving goods, thereby improving the efficiency of warehousing and outbound storage.

[0038] Regarding the load-carrying capacity of the telescopic fork 5 of this solution, since each level is equipped with a transmission belt 522, each transmission belt 522 evenly distributes the total load. This reduces the elasticity of each transmission belt 522, making it less susceptible to damage. This not only improves load-carrying capacity but also makes it easier to withstand the impact of a loss of load. This provides greater safety and reliability for wheel and brake disc storage systems that require high-load and high-speed storage and retrieval. It also makes it easier to ensure the proper placement of pallets 55 during storage and retrieval, preventing the center of gravity from shifting or being misplaced. Furthermore, even if damaged, only the damaged level needs to be disassembled, making maintenance easier.

[0039] Through the above structure, the telescopic plate 52 can enter the storage location 12 from below or directly into the storage location 12, and cooperate with the lifting mechanism 4 to complete the storage and retrieval actions. The structure has the characteristics of thin thickness and high load, which is especially suitable for the storage and retrieval needs of wheels and brake discs that are heavier but have a lower height in the storage location 12. At the same time, it can support two-way picking functions with a single Y-axis power, and can also perform high-speed picking requirements. The structure is more reliable, not easy to damage and easy to maintain.

[0040] Furthermore, for thin products such as wheels and brake discs that are flat in structure but have a large demand for use, this technical solution also improves the existing three-dimensional warehouse 1.

[0041] For example, Figure 1-4 As shown, the storage location 12 is a rectangular space, and support plates 121 are provided on both sides of the bottom of the storage location 12 for supporting both sides of the bottom of the cargo box K. The distance between the two support plates 121 in each storage location 12 is not less than the width of the pallet 55.

[0042] As an optional implementation of the present invention, wheels, also known as wheel cakes, are flat in shape, like brake discs. Currently, they are generally placed in a rectangular plastic frame (i.e., cargo frame K). Therefore, in order to increase the number of storage locations 12 in the three-dimensional warehouse 1 while maintaining the same volume, the storage locations 12 are designed to be relatively flat rectangular. In practice, each row of the three-dimensional warehouse 1 comprises a base frame consisting of multiple layers of horizontal crossbars 111 (X-axis) and multiple rows of vertical bars 112 (Z-axis, with two vertical bars 112 in each row). Each layer of crossbars 111 connects each row of vertical bars 112 on the exterior of the three-dimensional warehouse 1, thereby dividing the base frame into multiple layers of shelves 11. Two horizontally aligned vertical beams (Y-axis) connect the vertical bars 112 on one side of the warehouse with the connection between the vertical bars 112 and the crossbars 111 on the exterior of the warehouse, forming multiple grids to divide the storage locations 12. Support plates 121 are mounted on the vertical beams. These support plates 121 can be angled to enhance 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 in the vertical direction of the storage location 12 (in the case of no cargo frame K, it passes between the two support plates 121 when crossing the storage location 12). This ensures the aforementioned storage and retrieval method - the telescopic plate 52 directly enters the target storage location 12 or extends from under the target storage location 12, and then cooperates with the lifting and lowering of the lifting mechanism 4 to complete the storage and retrieval action of lifting the cargo frame K or lowering the cargo frame K.

[0043] The advantage of this implementation is that, within the same volume, more storage locations 12 can be designed. The height of each storage location 12 is approximately the thickness of the telescopic plate 52 + the height of the cargo frame K + the lifting margin of the lifting mechanism 4 (a margin of approximately 5 mm is sufficient). This maximizes the space utilization of the three-dimensional warehouse 1 while ensuring that the telescopic fork 5 can perform storage and retrieval functions. Of course, the specific structural strength of the three-dimensional warehouse 1 itself is related to the materials and specifications of the horizontal bars 111, vertical bars 113, and vertical bars 112 used. This can be calculated based on actual construction requirements and is not elaborated in detail in this technical solution.

[0044] Through the above structure, the utilization rate of the existing three-dimensional warehouse 1 is further optimized, and the thin telescopic fork 5 can be supported to perform the storage and retrieval tasks.

[0045] Furthermore, multi-stage telescopic technology has been shown in various fields to reduce load performance, accuracy, etc. when the number of stages reaches a certain level under the condition of the same elongation. Therefore, the number of stages of the telescopic plate 52 needs to be further limited.

[0046] For example, Figure 9-12As shown, the telescopic plate 52 includes two sub-plates 521 and two transmission belts 522. The two sub-plates 521 are respectively a primary plate 5211 and a secondary plate 5212. The two transmission belts 522 are respectively a primary transmission belt 5221 and a secondary transmission belt 5222. The telescopic plate 52 and the tray 55 form a three-stage telescopic plate 520. The primary plate 5211 is slidably connected to the bottom of the frame 51, and the primary transmission belt 5221 is rotatably connected to the primary plate 5211. The primary transmission belt 5221 is fixedly connected to the frame 51 at the lower portion of the primary plate 5211, and is fixedly connected to the secondary plate 5212 at the upper portion of the primary plate 5211. 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 secondary transmission belt 5222 is located below the secondary plate 5212 and is fixedly connected to the primary plate 5211. The secondary transmission belt 5222 is located above the secondary plate 5212 and is fixedly connected to the tray 55. The tray 55 is slidably connected to the secondary plate 5212 .

[0047] As an optional implementation of the present invention, considering that the actual storage and retrieval travel (Y-axis) in a stereoscopic warehouse 1 is not very large, and that existing multi-stage telescopic plates 52 with higher load performance requirements are generally three-stage telescopic plates 520, this technical solution also limits the entire telescopic fork 5 to a three-stage telescopic structure. In addition, to ensure accurate storage and retrieval of cargo frames K, the maximum width of the telescopic plates 52 and pallet 55 must be less than the spacing between the two support plates 121. When the telescopic plates 52 are in the retracted state, the geometric center and center of gravity of the pallet 55 must vertically coincide with the geometric center of the frame 51. Those skilled in the art may also incorporate anti-slip features on the top of the pallet 55, such as anti-slip scales and damping pads, to prevent the center of gravity from shifting during the transportation of cargo frames K, thereby preventing the inability to complete storage and retrieval tasks.

[0048] Furthermore, existing two-way storage and retrieval stacking solutions do not involve multi-stage telescopic technology. They generally use multiple power components (two), each of which is equipped with a fork, or use a two-way cylinder, or configure a reversing function for a single multi-stage telescopic plate 52. However, none of these implementation methods require the use of multiple power components, which either causes an increase in volume and is not suitable for the flat storage location 12, or increases the structural cost, or causes insufficient storage and retrieval efficiency due to the large number of execution steps.

[0049] For example, Figure 10-12 As shown, the primary transmission belt 5221 and the secondary transmission belt 5222 are at least one of a belt and a chain, and the primary plate 5211, the secondary plate 5212, and the tertiary plate are equal in length to the frame 51; When the telescopic fork 5 is in the retracted state, the primary transmission belt 5221 is fixed to the middle of the bottom of the frame 51 below the primary plate 5211, and the middle of the primary transmission belt 5221 is fixed to the middle of the secondary plate 5212 above the primary plate 5211. The secondary transmission belt 5222 is fixed to the middle of the primary plate 5211 at the middle below the secondary plate 5212 , and the secondary transmission belt 5222 is fixed to the middle of the tray 55 at the middle above the secondary plate 5212 .

[0050] As an optional implementation method of the present invention, after adopting the above-mentioned telescopic fork 5, it can be telescopic in both directions in the Y-axis direction, that is, the storage and retrieval tasks of the three-dimensional warehouses 1 on both sides of the stacker 2 can be met by a multi-stage telescopic plate 52, without the need for steering or adding additional power components. The power components and the fixing points of each transmission belt 522 and the adjacent plates are designed in the middle position to ensure that the maximum extension stroke of the telescopic fork 5 to the three-dimensional warehouses 1 on both sides is consistent. At the same time, the relative displacement of the primary plate 5211 relative to the base plate 511, the relative displacement of the secondary plate 5212 relative to the primary plate 5211, and the relative displacement of the pallet 55 relative to the secondary plate 5212 are equally divided into 1 / 3 of the total extension length. Therefore, when the primary plate 5211 moves to 1 / 3 of the total extension length designed for the telescopic plate 52, the entire telescopic plate 52 is fully extended, and the pallet 55 is completely entered into the storage position 12.

[0051] In this implementation, it is actually revealed that the lengths of the frame 51, the pallet 55, and the various distribution boards 521 are roughly equivalent to the length of the cargo frame K, and under the requirement of a compact structure of the three-dimensional warehouse 1, the width of the three-dimensional warehouse 1 (i.e., the length of the vertical beam) and the distance between the two three-dimensional warehouses 1 are roughly equivalent.

[0052] Through the above structure, under the condition of meeting the maximum utilization rate of the three-dimensional warehouse 1, the storage and retrieval tasks of the three-dimensional warehouses 1 on both sides can be performed by the same telescopic fork 5, and only one power component is required when the telescopic plate 52 is extended and retracted, ensuring that it can be used in the flat storage position 12, while reducing the overall structural cost.

[0053] Furthermore, the multi-stage telescopic plate 52 in the horizontal plane supports the cargo frame K to perform the storage and retrieval task. When the telescopic fork 5 is at the maximum extension stroke, the pallet 55 needs to have sufficient load.

[0054] For example, Figure 10-12As shown, a base plate 511 is provided at the bottom of the frame 51, the primary plate 5211 is slidably connected to the base plate 511 through the first guide rail 531, the secondary plate 5212 is slidably connected to the primary plate 5211 through the second guide rail 532, and the tray 55 is slidably connected to the secondary plate 5212 through 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 guide grooves, and the axial sections of the base plate 511, the primary plate 5211, the secondary plate 5212 and the tray 55 are all U-shaped with the opening 5111 facing upward, and the two V-shaped guide grooves in each guide rail have openings 5111 facing each other.

[0055] As an optional implementation of the present invention, a V-shaped chute is a commonly used guide rail. By limiting each level of the partition plate 521 to a U-shaped structure, and each guide rail is located on the two side walls of the U-shape, with the openings 5111 facing each other, each level of the partition plate 521 and the tray 55 are limited in both the Z-axis and X-axis directions, ensuring that the three-level telescopic plate 520 composed of each level of the partition plate 521 and the tray 55 has strong structural stability and is unlikely to separate from each other, thereby having more reliable load-bearing performance. Of course, this solution also further reduces the overall thickness of the three-level telescopic plate 520, which is more conducive to performing storage and retrieval tasks in the flat storage location 12.

[0056] It is worth noting that the guide rail can also adopt U-shaped or H-shaped slide grooves. Their principles are the same as those of the V-shaped slide grooves and can be regarded as equivalent replacement solutions for the V-shaped slide grooves.

[0057] The above structure ensures the structural stability and load performance of the telescopic fork 5 , and further reduces the thickness of the telescopic plate 52 , which is beneficial for application in a flat storage location 12 .

[0058] Furthermore, an extension plate 52111 is provided on one side of the first plate 5211 in the width direction, and the first transmission belt 5221 is rotatably connected to the extension plate 52111. The portion of the first transmission belt 5221 located above the first plate 5211 is fixedly connected to the side wall of the second plate 5212.

[0059] As an optional implementation method of the present invention, the first-level transmission belt 5221 is installed through the extension plate 52111. Compared with the method of installing the transmission belt 522 in the U-shaped groove of the first-level plate 5211, it can well avoid the installation space of the second-level transmission belt 5222, and there is no need to increase the distance between the first-level plate 5211 and the second-level plate 5212, ensuring that the overall thickness of the telescopic plate 52 is at a lower parameter.

[0060] Further, such as Figure 9-12As shown, the base plate 511, the primary plate 5211, and the secondary plate 5212 are all detachably connected with a fixing block 54 for fixing the transmission belt 522, and the fixing block 54 includes at least one of a clamping plate 543, a screw, and a buckle.

[0061] As an optional implementation of the present invention, the detachable connection mode facilitates rapid maintenance and replacement of the transmission belt 522. For the transmission belt 522, both a belt and a chain can be used, and this technical solution does not limit this.

[0062] like Figure 12 As shown, the base plate 511 and the primary plate 5211 are both provided with an opening 5111 for installing 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 threadedly connected to the opening 5111, the clamping plate 543 is threadedly connected to the pad 542, and the pad 542 is threadedly connected to the U-shaped base 541; the opening 5111 on the base plate 511 is located on the extension plate 52111.

[0063] As an optional implementation method of the present invention, the splint 543, as the name implies, is two plates that can clamp the transmission belt 522. Of course, it can also be a plate that cooperates with the pad 542 to fix the transmission belt 522. This method does not damage the structure of the transmission belt 522 itself and ensures the tensile strength of the transmission belt 522 itself. In addition, the design of the U-shaped base 541 ensures that the overall thickness of the entire fixing block 54 is not too large. The threaded connection method can simultaneously meet the requirements of maintainability and connection strength. Of course, when the transmission belt 522 undergoes slight plastic deformation, the transmission belt 522 can be replaced directly instead of directly. Instead, the thickness of the pad 542 can be replaced with a smaller pad 542 so that the tension of the installed transmission belt 522 meets the requirements. This makes it unnecessary to completely remove the transmission belt 522. If a single transmission belt 522 is directly removed and replaced, the steps involve the disassembly of at least three plates. Therefore, replacing the pad 542 is more efficient for maintenance.

[0064] With the above structure, the maintenance efficiency of the telescopic plate 52 is improved.

[0065] like Figure 9-11 As shown, a rack 561 is fixedly connected to the bottom of the primary plate 5211, and the driving mechanism 56 is a gear motor 562; a rack 561 is fixedly connected to the bottom of the primary plate 5211, and the driving 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.

[0066] As an optional implementation of the present invention, the use of rack 561 and gear motor 562 has the advantage of being relatively compact, and the motor configuration facilitates servo or stepper control, improving precise control of the telescopic stroke. The advantage of designing three proximity switches 57 and evenly distributing them is that they facilitate simultaneous detection of the maximum displacement in the Y- and Y+ directions.

[0067] Specifically, when the primary plate 5211 moves along the Y+ direction, the proximity head 58 close to the Y- direction is aligned with the middle proximity switch 57, the proximity switch 57 is triggered, and sends an instruction to the control system to control the gear motor 562 to stop rotating and control the lifting mechanism 4 to operate.

[0068] Example 2: Furthermore, considering that the transmission belt 522 is in the form of a chain or a belt, they are subject to tensile deformation, which will lead to inaccurate standard displacement of adjacent level plates. In severe cases, the transmission belt 522 is too loose, resulting in the pallet 55 not being able to accurately reach the appropriate position at the bottom of the cargo frame K, causing the center of gravity to be further away from the telescopic fork 5 when storing and retrieving goods, aggravating the aging rate of the guide rail and the transmission belt 522; in extreme cases, there is a possibility that the pallet 55 fails to reach its position, causing the cargo frame K to tilt when it is lifted by the pallet 55, causing the wheels and brake discs in the warehouse to fall off, affecting the use of the entire storage warehouse, or the pallet 55 and / or cargo frame K cannot fully enter the carrying space of the frame 51, or the pallet 55 / cargo frame K part cannot completely escape from the storage position 12, or the pallet 55 cannot completely deliver the cargo frame K into the storage position 12. These situations are likely to cause collisions during the operation of the stacker 2. In addition, 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, and the wear of the guide rail will be aggravated, especially in scenarios where the load is heavier (a single one can reach several tons) such as wheels and brake discs. The wear is very obvious, especially the upper wall of the guide rail. In severe cases, it will cause the pallet 55 to tilt, resulting in the pallet 55 being unable to enter the storage location 12 with a lower margin (such as the aforementioned lifting margin of only 5 mm, the lifting margin is expressed as: when the cargo frame K is placed in the lower storage location 12, the distance between the top of the cargo frame K and the bottom of the upper cargo frame K), and thus unable to perform the task of storing and retrieving goods.

[0069] For example, Figure 11 As shown, cameras 6 for detecting the distance between the edge of the pallet 55 and the inner side of the cargo box K are further provided at both ends of the pallet 55 in the Y-axis direction.

[0070] As an optional implementation of the present invention: When the pallet 55 extends into the storage location 12, an image of the bottom of the cargo box K is obtained; After binarizing the bottom image of the cargo box K, the first standard distance image is called and compared with the processed bottom image of the cargo box K to calculate the vertical and horizontal distances from the edge of the current pallet 55 to the bottom edge of the cargo box K; The air transport tilt angle of the pallet 55 is further calculated based on the vertical distance and the horizontal distance; Determine whether the extension distance and tilt angle of the tray 55 reach a safety threshold and a maintenance threshold; When the maintenance threshold is reached, a maintenance alarm is triggered; when the safety threshold is reached, an alarm is immediately issued and the currently executing access task is stopped.

[0071] In this implementation, the first standard distance image is the calibration image, which is an image captured before the transmission belt 522 and the guide rail have performed any access tasks. It serves as a reference for calculating the distance from the edge of the cargo box K to the end of the pallet 55 and is stored in the system in advance. The camera 6 can be a common camera 6 used for image detection. Since there may be no light in this storage warehouse, a lamp 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 + battery or wired. Since image acquisition technology has been maturely used in the field of edge detection in industry, this technical solution does not elaborate on the specific image processing methods of these existing technologies. The safety threshold and maintenance threshold are set in advance. Of course, the specific threshold range is not limited in this technical solution.

[0072] Preferably, the maintenance threshold has an extension distance of 2-10 mm and an inclination angle of 0.1-0.5°, and the safety threshold has an extension distance greater than or equal to 10 mm and an inclination angle greater than or equal to 0.5°.

[0073] In this embodiment, after the pallet 55 enters the storage location 12, it receives an in-position signal from the proximity switch 57, then obtains an image of the bottom edge of the cargo frame K. This image is then compared with a standard image as a reference, thereby determining the inclination angle of the pallet 55 when it is in the empty transport state (i.e., when performing a pickup task) and the center of gravity of the cargo frame K when placed on the pallet 55. This further enables the determination of the degree of stretching of the transmission belt 522 and the degree of wear of the guide rails, thereby determining whether the current pickup task can continue. If it can, it will continue; if it cannot, it will determine whether maintenance is required, and if it cannot, it will directly stop the current task. This can avoid the problem of the inability to perform the storage and retrieval task due to increased wear of the guide rails or excessive looseness of the transmission belt 522. It can also prompt the operator to repair the telescopic fork 5 when a certain degree of wear or looseness is reached, thereby extending the service life of the telescopic fork 5.

[0074] Furthermore, there is a situation where the pallet 55 cannot enter the storage location 12 due to an excessively large tilt angle (especially when entering the storage). Therefore, the tilt angle of the pallet 55 also needs to be detected before the pallet 55 enters the storage location 12.

[0075] Exemplarily, before the pallet 55 enters the storage location 12, the following steps are also included: Obtain the image of location 12 and perform binarization processing on the image; Retrieve the second standard distance image and compare it with the processed image of storage location 12 to calculate the vertical and horizontal distances from the current pallet 55 to storage location 12; The load tilt angle of the pallet 55 is further calculated based on the vertical distance and the horizontal distance; Determine whether the tilt angle of the tray 55 exceeds a safety threshold and a maintenance threshold; When the maintenance threshold is reached, a maintenance alarm is triggered; when the safety threshold is reached, an alarm is immediately issued and the currently executing access task is stopped.

[0076] With this implementation, before pallet 55 enters storage location 12, it receives an arrival signal from lifting mechanism 4. It then captures an image of storage location 12 (which can be the vertical poles 112 and the ends of vertical poles 113 at the storage entrance, or the storage entrance defined by support plate 121, vertical poles 112, and vertical poles 113). Using a standard image as a reference for comparison, the tilt angle of pallet 55 under load (i.e., when performing a storage task) and the center of gravity of the cargo frame K when placed on pallet 55 can be determined. This allows the operator to determine the stretch level of drive belt 522 and the wear level of the guide rails, thereby determining whether pallet 55 can still enter storage location 12 and, consequently, whether the retrieval task can continue. If so, the task can continue. If not, maintenance is determined, and the task is aborted. This prevents storage and retrieval tasks from failing due to increased wear of the guide rails or excessive looseness of the drive belt 522. Furthermore, when a certain degree of wear or looseness is reached, the operator is prompted to repair the telescopic fork 5, thereby extending the service life of the telescopic fork 5.

[0077] Example 3: like Figure 13-14 As shown, based on Example 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. The frame 51 is slidably connected to the Z-axis guide column 43 through a guide frame 59. The guide frame 59 includes: A vertical plate 591, one side of which is fixedly connected to the frame 51; Back plates 592 , where the two back plates 592 are fixedly connected to the side of the vertical plate 591 away from the frame 51 ; The Y-axis guide wheel 593 is rotatably connected to the back plate 592, and the Y-axis guide wheel 593 clamps the Z-axis guide column 43 from both sides of the X direction of the Z-axis guide column 43; The X-axis guide wheel 594 is rotatably connected to the back plate 592. The X-axis guide wheel 594 is distributed on the two back plates 592 respectively. The two back plates 592 clamp the two Z-axis guide columns 43 from both sides of the column 41 in the Y-axis direction. Each back plate 592 is provided with two vertically aligned X-axis guide wheels 594.

[0078] As an optional implementation of the present invention, when the telescopic plate 52 extends into the storage location 12 during the storage and retrieval process, the center of gravity of the entire telescopic fork 5 shifts, causing a pulling force on the lifting mechanism 4. Especially when the storage and retrieval task is performed at a higher storage location 12, the force acting on the lifting mechanism 4 is more obvious. 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 walking mechanism 3 moves in the three-dimensional warehouse 1, the Y-axis guide wheel 593 enables the telescopic fork 5 to better resist the instantaneous impact force in the X-axis direction, and also improves the connection stability between the telescopic fork 5 and the lifting mechanism 4.

[0079] The working principle and usage process of the present invention are as follows: when entering the warehouse, the walking mechanism 3 moves to the entrances and exits on both sides of the three-dimensional warehouse 1, and the lifting mechanism 4 drives the telescopic fork 5 to the automatic conveyor line aligned with the entrance and exit, the telescopic fork 5 is extended, and the automatic conveyor line conveys the cargo frame K to the telescopic fork 5. After the telescopic fork 5 is retracted, the lifting mechanism 4 and the walking mechanism 3 move the telescopic fork 5 to the target storage location 12, and then the telescopic fork 5 is extended into the storage location 12 to place the cargo frame K in the storage location 12, thereby completing the warehousing; when leaving the warehouse, the walking mechanism 3 and the lifting mechanism 4 are linked to drive the telescopic fork 5 to move to the target storage location 12, the telescopic fork 5 is extended into the storage location 12, the lifting mechanism 4 rises and lifts the cargo frame K and then retracts, so that the cargo frame K is taken out from the storage location 12, and then the lifting mechanism 4 and the walking mechanism 3 are linked to drive the cargo frame K to the entrance and exit of the three-dimensional warehouse 1, and place the cargo frame K on the automatic conveyor line.

[0080] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
