AI Technical Summary
[0003]专利公布号为CN104787534A的发明申请文件中公开了一种顶升式自动长杆物料存取方法及其装置，该发明申请文件主要用于储存长杆物料，然而该装置存在以下技术缺点：1、该装置的升降车利用四根升降链条构成了升降系统进行上下升降运动，但是这种升降系统容易发生晃动；这样导致升降车升降运输物料时不安全，准确度也不高；2、该装置的升降车利用托板和料斗上的支撑立板相互配合接触提升物料，因此立库上需要使用料斗，由于立库的库位比较多，每个库位均需要一个料斗，因此，立库上需要额外承受多个立库的重量，而同时，由于托板支撑的料斗的两端，整个料斗的中部为悬空状态，所以料斗上的支撑立板承重非常大，因此，若料斗中的物料重量比较重时，对支撑立板与料斗之间的连接部位的牢固程度要求非常高；3、该装置的升降车在取料时，利用横移系统将托板移动到支撑立板的下方，而然后升降车上升支撑料斗，然而由托板横向平移到料斗下方后，此时提起料斗后升降车整体的重心会发生偏移，从而可能导致升降车倾斜，存在安全隐患；4、该装置只能适合长杆物料的存取，若是短物料，巷道两侧就会有由多个库位排列的一排库位，此时该装置就难以从一排库位中存取物料
[0015]采用了上述技术方案后，本实用新型的效果是：由于每个巷道的至少一端设置有竖直设置的库内导向柱，所述存取载台上设置有与库内导向柱的侧壁限位配合的升降限位结构，所述存取载台处于上极限工位时升降限位结构与库内导向柱分离，所述天车上还固定有与库内导向柱位上端竖直对应的车内导向柱，所述存取载台处于上极限工位时升降限位结构与车内导向柱限位配合，所述存取载台上设置有将物料存放至巷道两侧的库位上或者将物料从库位中取出的存取机构，所述存取载台和天车之间还设置有用于检测存取载台高度的高度检测装置，因此，该存取载台在升降的过程中会被库内导向柱和车内导向柱进行导向限位，从而存取载台的升降运行非常平稳，不会出现晃动的情况，而同时，由于车内导向柱是固定在天车上，因此会随着天车移动，这样也能保证存取载台在随天车移动的时候不晃动，库内导向柱和车内导向柱相互衔接对接，方便存取载台与库内导向柱脱开，这样不妨碍天车的移动。而高度检测装置可以用来检测存取载台的升降高度，使其与对应高度的库位准确对应。而存取载台上的存取机构则可以方便将物料从库位中取出或者存入库位中。该存取进出库系统在存取物料时更加的稳定，确保存取动作的顺畅可靠。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent automated storage and retrieval technology, and in particular to an intelligent automated storage and retrieval system for inbound and outbound operations. Background Technology
[0002] Intelligent automated warehouses, also known as intelligent three-dimensional warehouses, utilize the collaboration of automated storage equipment and computer management systems to achieve a high degree of rationalization, automated storage and retrieval, and simplified operation of automated warehouses.
[0003] Patent application CN104787534A discloses a lifting-type automatic long-pole material storage and retrieval method and device. This invention is mainly used for storing long-pole materials. However, the device has the following technical drawbacks: 1. The lifting vehicle of this device uses four lifting chains to form a lifting system for vertical movement, but this lifting system is prone to swaying; this makes the lifting vehicle unsafe and inaccurate when transporting materials; 2. The lifting vehicle of this device uses the cooperation of the pallet and the support plate on the hopper to lift the material, therefore, the vertical storage unit needs to use a hopper. Since the vertical storage unit has many storage locations, each location requires a hopper, thus the vertical storage unit needs to bear the weight of multiple storage units. Furthermore, due to… The hopper is supported by pallets at both ends, with the middle of the hopper suspended in the air. Therefore, the supporting plates on the hopper bear a very heavy load. Thus, if the material in the hopper is heavy, the connection between the supporting plates and the hopper must be very secure. 3. When the lifting vehicle of this device retrieves material, it uses a lateral movement system to move the pallet under the supporting plates. Then, the lifting vehicle rises to support the hopper. However, after the pallet is moved laterally under the hopper, the center of gravity of the lifting vehicle will shift after the hopper is lifted, which may cause the lifting vehicle to tilt, posing a safety hazard. 4. This device is only suitable for storing and retrieving long materials. If the material is short, there will be a row of storage locations arranged in multiple positions on both sides of the aisle. In this case, it is difficult for this device to store and retrieve materials from a row of storage locations. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an intelligent vertical storage and retrieval system, which limits and guides the storage and retrieval platform when storing and retrieving materials, so as to make the storage and retrieval operation more stable.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an intelligent vertical storage and retrieval system, including a frame, a ceiling track is provided on the frame above the intelligent vertical storage, a movable trolley is horizontally slidably mounted on the ceiling track along the X direction, and a storage and retrieval platform that can be raised and lowered along the Z direction is installed below the trolley via a suspension and traction mechanism. The storage and retrieval platform is driven by a lifting power device mounted on the trolley to rise and fall between the upper limit position and the lower limit position. The intelligent vertical storage is provided with a plurality of aisles to accommodate the storage and retrieval platform, and at least one end of each aisle is provided with a vertically arranged storage compartment. The storage and retrieval platform is equipped with a lifting and limiting structure that cooperates with the side wall limit of the guide column inside the warehouse. When the storage and retrieval platform is in the upper limit position, the lifting and limiting structure is separated from the guide column inside the warehouse. The overhead crane is also fixed with an internal guide column that is vertically corresponding to the upper end of the guide column inside the warehouse. When the storage and retrieval platform is in the upper limit position, the lifting and limiting structure cooperates with the internal guide column. The storage and retrieval platform is equipped with a storage and retrieval mechanism for storing materials in the warehouse positions on both sides of the aisle or retrieving materials from the warehouse positions. A height detection device for detecting the height of the storage and retrieval platform is also provided between the storage and retrieval platform and the overhead crane.
[0006] As a preferred embodiment, the lifting and limiting structure includes at least four side limiting wheels rotatably mounted on both ends of the storage and retrieval platform. The rotation center of the side limiting wheels extends in the Y direction. The side limiting wheels form a vertical limiting channel that facilitates the passage of the guide pillars inside the storage area and the guide pillars inside the vehicle. The side limiting wheels roll in cooperation with the opposite side walls of the guide pillars inside the storage area and the guide pillars inside the vehicle.
[0007] As a preferred embodiment, the lifting and limiting structure further includes at least one intermediate limiting wheel rotatably mounted at both ends of the storage and retrieval platform. The extension direction of the rotation center of the intermediate limiting wheel is parallel to the X direction. The intermediate limiting wheel is located in the vertical limiting channel and rolls with the inner surface of the guide column inside the warehouse and the guide column inside the vehicle.
[0008] As a preferred embodiment, the storage and retrieval platform includes a platform body extending along the Y direction. Both ends of the platform body are fixed with end plates. Each end plate is provided with two suspension points. The suspension points are connected to the suspension and traction mechanism. The storage and retrieval mechanism is disposed on the platform body. The center of gravity of the materials in the storage locations on both sides of the aisle is located between the two suspension points on the same end plate.
[0009] As a preferred embodiment, the access mechanism is a telescopic fork, which is fixed in the middle of the platform body.
[0010] As a preferred embodiment, the storage and retrieval mechanism is a push-pull type, which includes a base, on which a storage and retrieval slide is slidably mounted along the X direction. A storage and retrieval power device for driving the storage and retrieval slide is mounted on the base. At least two parallel, cyclically running push-pull chains are mounted on the storage and retrieval slide. The push-pull chains are driven by the push-pull power device to run in both forward and reverse cycles. Each push-pull chain has two push-pull blocks spaced apart. Correspondingly, a material frame is placed in the storage location. The material frame has spaced-apart open slots that engage with the corresponding push-pull blocks. When the push-pull blocks on the push-pull chains run in cycles, they engage with the open slots.
[0011] As a preferred embodiment, the platform body is provided with a Y-guide rail extending along the Y direction, and the storage and retrieval mechanism is slidably mounted on the Y-guide rail along the Y direction and driven by a Y-sliding power device. Correspondingly, the number of storage locations on the same side and at the same height in the same alley is at least two and arranged along the Y direction.
[0012] As a preferred embodiment, the lower end of the in-vehicle guide column is provided with a downwardly tapering lower guide section, and the upper end of the corresponding in-garage guide column is provided with an upwardly tapering upper guide section, with the lower guide section and the upper guide section directly opposite each other.
[0013] As a preferred option, the suspension traction mechanism is a wire rope traction mechanism or a chain traction mechanism.
[0014] As a preferred embodiment, the lowest part of the intelligent automated storage and retrieval system is provided with a storage and retrieval connection area, in which an RGV trolley is installed. The RGV trolley connects with the storage and retrieval platform to deliver materials out or into the system.
[0015] After adopting the above technical solution, the effect of this utility model is as follows: Since each tunnel has at least one vertically installed in-warehouse guide post, and the storage / retrieval platform is equipped with a lifting and limiting structure that cooperates with the side wall limiting of the in-warehouse guide post, the lifting and limiting structure separates from the in-warehouse guide post when the storage / retrieval platform is at its upper limit position. The overhead crane also has an in-vehicle guide post vertically corresponding to the upper end of the in-warehouse guide post. When the storage / retrieval platform is at its upper limit position, the lifting and limiting structure cooperates with the in-vehicle guide post. The storage / retrieval platform is equipped with storage positions on both sides of the tunnel or for moving materials from the storage positions. The storage and retrieval mechanism is equipped with a height detection device between the storage and retrieval platform and the overhead crane. Therefore, during the lifting and lowering process, the platform is guided and limited by the guide columns inside the storage unit and the crane, ensuring smooth lifting and lowering without swaying. Simultaneously, since the guide columns inside the crane are fixed to the crane, they move with the crane, further preventing swaying of the platform. The guide columns inside the storage unit and the crane are interconnected, facilitating the separation of the platform from the guide columns without obstructing the crane's movement. The height detection device monitors the lifting height of the platform, ensuring accurate alignment with the corresponding storage location. The storage and retrieval mechanism on the platform allows for convenient removal or storage of materials from or into storage locations. This storage and retrieval system provides greater stability during material handling, ensuring smooth and reliable operations.
[0016] Furthermore, since the lifting and limiting structure includes at least four side limiting wheels rotatably mounted at both ends of the storage and retrieval platform, and the rotation center of the side limiting wheels extends in the Y direction, the side limiting wheels form a vertical limiting channel that facilitates the passage of the guide pillars inside the storage area and the guide pillars inside the vehicle. The side limiting wheels roll in cooperation with the opposite side walls of the guide pillars inside the storage area and the guide pillars inside the vehicle. Therefore, the lifting and limiting structure utilizes the four side limiting wheels to roll in cooperation with the sides of the guide pillars inside the storage area and the guide pillars inside the vehicle, thus achieving the limiting function. At the same time, the rolling cooperation also ensures smooth lifting and lowering of the storage and retrieval platform.
[0017] Furthermore, since the lifting and limiting structure also includes at least one intermediate limiting wheel rotatably installed at both ends of the storage and retrieval platform, the extension direction of the rotation center of the intermediate limiting wheel is parallel to the X direction, the intermediate limiting wheel is located in the vertical limiting channel, and the intermediate limiting wheel rolls with the inner side of the guide column in the warehouse and the guide column in the vehicle. Therefore, the intermediate limiting wheel rolls with the guide column in the warehouse and the guide column in the vehicle to perform a step of limiting and guiding in the Y direction.
[0018] Furthermore, since the storage and retrieval platform includes a platform body extending along the Y direction, and both ends of the platform body are fixed with end plates, each end plate is provided with two suspension points. The suspension points are connected to the suspension and traction mechanism. The storage and retrieval mechanism is set on the platform body. The center of gravity of the materials in the storage locations on both sides of the aisle is located between the two suspension points on the same end plate. In this way, when the storage and retrieval mechanism performs storage and retrieval operations on the platform body, since the suspension points are located outside the center of the materials in the storage location, the center of gravity of the materials is kept within the range of the storage and retrieval platform during the entire storage and retrieval process, avoiding the phenomenon of the storage and retrieval platform tilting during the storage and retrieval process. Then, in conjunction with the lifting and limiting structure, the tilting of the storage and retrieval platform is further avoided.
[0019] Furthermore, since the storage and retrieval mechanism is a telescopic fork, which is fixed in the middle of the platform body, the telescopic fork can be directly inserted from the bottom under the material. Then, the storage and retrieval platform rises to lift the material, and the fork retracts to remove the material. Similarly, when storing materials, only the reverse action is required. This storage and retrieval mechanism, in conjunction with the action of the storage and retrieval platform, can complete the storage and retrieval of materials. The entire process does not require additional material baskets, and materials can be stored and retrieved in bundles, thereby saving the space and weight occupied by material baskets.
[0020] Furthermore, since the storage and retrieval mechanism is a push-pull type, the push-pull type storage and retrieval mechanism includes a base, on which a storage and retrieval slide is slidably mounted along the X direction. A storage and retrieval power device is mounted on the base to drive the storage and retrieval slide to slide. At least two parallel, cyclically running push-pull chains are mounted on the storage and retrieval slide. The push-pull chains are driven by the push-pull power device to run in both forward and reverse cycles. Each push-pull chain has two push-pull blocks spaced apart. Correspondingly, a material frame is placed in the storage location. The material frame has spaced-apart open slots that engage with the corresponding push-pull blocks. When the push-pull blocks on the push-pull chains run in cycles, they engage with the open slots. The storage and retrieval of the material frame can also be realized through the push-pull storage and retrieval mechanism.
[0021] Furthermore, since the platform body is equipped with a Y-guide rail extending along the Y direction, and the storage and retrieval mechanism is slidably mounted on the Y-guide rail along the Y direction and driven by a Y-sliding power device, the number of storage locations on the same side and at the same height in the same aisle is at least two and arranged along the Y direction. In this way, the storage and retrieval system can be suitable for storing and retrieving short materials in multiple storage locations. When it is necessary to store or retrieve materials in a certain storage location on one side of the aisle, the platform body only needs to be lowered to the corresponding height, and then the storage and retrieval mechanism moves along the Y direction, so that materials in any storage location at that height can be stored or retrieved, adapting to the storage and retrieval of short materials in multiple storage locations.
[0022] Furthermore, since the lower end of the vehicle guide column is provided with a downwardly tapering lower guide opening, and the upper end of the corresponding warehouse guide column is provided with an upwardly tapering upper guide opening, and the lower guide opening and the upper guide opening are directly connected to each other, the lifting and limiting structure can easily enter and exit the vehicle guide column and the warehouse guide column through the lower guide opening and the upper guide opening.
[0023] Furthermore, since the lowest part of the intelligent automated storage and retrieval system is equipped with a storage and retrieval connection area, and an RGV trolley is installed in the storage and retrieval connection area, the RGV trolley connects with the storage and retrieval platform to deliver or receive materials. Therefore, the storage and retrieval platform can deliver materials to the RGV trolley or remove materials from the RGV trolley. This makes the storage and retrieval cycle of the RGV trolley and the storage and retrieval platform more compact and saves storage and retrieval time. Attached Figure Description

[0034] The present invention will be further described in detail below through specific embodiments.
[0035] Example 1
[0036] like Figures 1 to 4 As shown, an intelligent automated storage and retrieval system (AS / RS) 1 includes a frame. A ceiling track 9 is mounted on the frame above the AS / RS 1, and a movable overhead crane 2 is horizontally slidably mounted on the ceiling track 9 along the X-direction. In this embodiment, the frame can be a separate unit independent of the AS / RS 1, in which case the entire AS / RS 1 is positioned below the frame. Alternatively, the entire AS / RS 1 can be used as a supporting frame, with the ceiling track 9 mounted on the top frame of the AS / RS 1.
[0037] Below the overhead crane 2, a storage and retrieval platform 3 that can be raised and lowered along the Z direction is installed via a suspension and traction mechanism. The storage and retrieval platform 3 is driven by a lifting power device installed on the overhead crane 2 to rise and fall between the upper limit position and the lower limit position.
[0038] In this embodiment, the overhead crane 2 includes a crane frame 21, on which a platform window 23 is provided for accommodating the lifting and lowering of the access platform 3. A track extending in the X direction is provided on the frame, and a traveling mechanism 22 that travels along the track extending in the X direction is provided on the crane frame 21. The intelligent automated storage and retrieval system 1 has several aisles 5 for accommodating the access platform 3. When the access platform 3 is within the platform window 23 and higher than the intelligent automated storage and retrieval system 1, the access platform 3 leaves the area of the intelligent automated storage and retrieval system 1 and moves with the overhead crane 2 into any aisle 5. The traveling mechanism 22 on the overhead crane 2 is a conventional structure and will not be described in detail here.
[0039] The suspension and traction mechanism is either a wire rope traction mechanism or a chain traction mechanism. In this embodiment, a wire rope traction mechanism is preferred. Correspondingly, a winding power device 24 for winding the wire rope is provided on the overhead crane frame 21. This winding power device 24 is a lifting power device. Four hanging rings 36 arranged in a rectangle are provided on the storage and retrieval platform 3. The hanging rings 36 are connected to the wire rope. The overhead crane 2 is also provided with wire guide wheels 25 to facilitate the winding and unwinding of the wire.
[0040] In this embodiment, the storage and retrieval platform 3 includes a platform body 31 extending along the Y direction. Both ends of the platform body 31 are fixed with end plates 32. Each end plate 32 is provided with two suspension points. Hanging rings 36 are provided on the suspension points and are connected to the suspension traction mechanism by means of the hanging rings 36. The storage and retrieval mechanism 33 is provided on the platform body 31. The center of gravity of the material 8 on the storage position A on both sides of the aisle 5 is located between the two suspension points on the same end plate 32.
[0041] In this embodiment, the storage and retrieval mechanism 33 is a telescopic fork 332, which is fixed to the middle of the platform body 31. The telescopic fork 332 is a conventional structure in palletizing machines and is a common structure on the market. For example, a smoothly guided telescopic fork is disclosed in patent application CN222715040U. In this embodiment, there is one storage location A at the same height on both sides of the same aisle 5, for example, some long pipes, bars, or profiles. At this time, the telescopic fork 332 can slide in both directions. The telescopic fork 332 is set in the middle position, and the distance between the support arms of the forks is relatively wide, so as to stably support the material 8.
[0042] Meanwhile, the center of gravity of material 8 in storage location A is located between two suspension points on the same end plate 32. Thus, when the telescopic fork 332 is inserted under material 8, the storage platform 3 rises to lift material 8. Since the center of gravity of material 8 is still between the suspension points when lifting material 8, the storage platform 3 is more stable when storing and retrieving material 8.
[0043] like Figure 3 and Figure 4As shown, each lane 5 has at least one vertically arranged in-warehouse guide post 6 at one end. The storage and retrieval platform 3 is provided with a lifting and limiting structure that cooperates with the side wall limiting of the in-warehouse guide post 6. When the storage and retrieval platform 3 is in the upper limit position, the lifting and limiting structure is separated from the in-warehouse guide post 6. The overhead crane 2 is also fixed with an in-vehicle guide post 7 that is vertically corresponding to the upper end of the in-warehouse guide post 6. When the storage and retrieval platform 3 is in the upper limit position, the lifting and limiting structure cooperates with the in-vehicle guide post 7. The storage and retrieval platform 3 is provided with a storage and retrieval mechanism 33 for storing materials 8 in the warehouse positions A on both sides of the lane 5 or for retrieving materials 8 from the warehouse positions A. A height detection device for detecting the height of the storage and retrieval platform 3 is also provided between the storage and retrieval platform 3 and the overhead crane 2.
[0044] In this embodiment, the height detection device uses a laser rangefinder sensor for detection. The laser rangefinder sensor body can be installed on the access platform 3 or the overhead crane 2, and a reference plate is installed on the overhead crane 2 or the access platform 3, so as to determine the height of the access platform 3 by laser rangefinder.
[0045] In this embodiment, the lifting and limiting structure includes at least four side limiting wheels 34 rotatably mounted on the end plate 32 of the storage and retrieval platform 3. The rotation center of each side limiting wheel 34 extends in the Y direction. The side limiting wheels form a vertical limiting channel that facilitates the passage of the guide pillars 6 and 7 inside the storage compartment. The limiting wheels roll in cooperation with the opposite side walls of the guide pillars 6 and 7 inside the storage compartment. In this embodiment, guide pillars 6 inside the storage compartment are provided at both ends of the aisle 5. Therefore, side limiting wheels 34 are also provided on the end plates 32 at both ends of the storage and retrieval platform 3.
[0046] The lifting and limiting structure also includes at least one intermediate limiting wheel 35 rotatably mounted at both ends of the storage and retrieval platform 3. The extension direction of the rotation center of the intermediate limiting wheel 35 is parallel to the X direction. The intermediate limiting wheel 35 is located in a vertical limiting channel and rolls with the inner surfaces of the guide pillars 6 and 7 inside the storage compartment. Therefore, through the guiding cooperation between the side limiting wheels 34 and the intermediate limiting wheels 35 and the guide pillars 6 and 7 inside the storage compartment, the lifting and lowering of the storage and retrieval platform 3 is ensured to be stable and smooth.
[0047] The lower end of the in-vehicle guide column 7 is provided with a downwardly tapering lower guide opening 71, and the upper end of the corresponding in-vehicle guide column 6 is provided with an upwardly tapering upper guide opening 61. The lower guide opening 71 and the upper guide opening 61 are directly opposite each other. Of course, in this embodiment, a proximity switch is provided on the in-vehicle guide column 7, so as to control the uppermost limit position of the storage platform 3.
[0048] In this embodiment, a storage and retrieval connection area B is provided at the bottom of the intelligent automated storage and retrieval system 1. An RGV trolley 4 is installed in the storage and retrieval connection area B, and the RGV trolley 4 connects with the storage and retrieval platform 3 to deliver or receive materials 8. Figure 2 As shown, the bottom layer of the intelligent automated warehouse 1 is the storage and retrieval connection area B. Correspondingly, the RGV trolley 4 can move along the track within the storage and retrieval connection area B. The direction of movement of the RGV trolley 4 can be set according to the actual layout of the intelligent automated warehouse 1. For example, it can move along the Y direction or / and the X direction, so that it can enter and exit the warehouse from different positions, making it more adaptable.
[0049] While the RGV trolley 4 is moving out or being delivered, the storage and retrieval platform 3 can simultaneously perform other inbound and outbound operations, making the entire storage and retrieval cycle more compact and efficient.
[0050] Example 2
[0051] like Figure 5 As shown, the structure in this embodiment is basically the same as that in Embodiment 1. Figure 5 In this configuration, the platform body 31 is provided with a Y-guide rail 39 extending along the Y direction. The storage and retrieval mechanism 33 is slidably mounted on the Y-guide rail 39 along the Y direction and driven by a Y-sliding power device 37. Correspondingly, there are at least two storage locations A on the same side and at the same height in the same aisle 5, arranged along the Y direction, which allows for the storage of shorter materials 8. Therefore, the telescopic fork 332 is slidably mounted on the storage and retrieval platform 3 along the Y direction and driven by the Y-sliding power device 37, so the telescopic fork 332 can correspond to storage locations A at different positions on the same height in the same aisle 5.
[0052] In this embodiment, the telescopic fork 332 can be used to store or retrieve materials, or the material frame 10 can be used without the material frame 10, for example, directly placing the bundled materials 8.
[0053] The Y-sliding power unit 37 uses a servo motor and can be driven by the traction chain 38 to move the entire telescopic fork 332 along the Y direction.
[0054] Example 3
[0055] like Figures 6 to 8As shown, the structure in this embodiment is basically the same as that in embodiment 1, except that the access mechanism 33 adopts a push-pull access mechanism 33. The push-pull access mechanism 33 includes a base 331, on which an access slide 333 is slidably mounted along the X direction. An access power device for driving the access slide 333 to slide is mounted on the base 331. In this embodiment, the access power device is a motor. The base 331 can slide in the X direction through a gear 334 and rack 335 mechanism. The gear 334 is rotatably mounted on the access slide 333 through a transmission shaft, while the rack 335 is fixed on the base 331. A synchronous pulley is also mounted on the transmission shaft. The motor drives the synchronous pulley to rotate using a synchronous belt, which in turn drives the gear 334 to rotate, thereby realizing the sliding of the access slide 333.
[0056] At least two parallel, cyclically running push-pull chains 336 are installed on the access slide 333. These chains are driven in both directions by a push-pull power device 337, which is a motor driven by a synchronous belt. A synchronous pulley is fixed to the chain shaft 338 of each push-pull chain 336, and the chain drives the push-pull power device 337 via the synchronous belt. Each push-pull chain 336 has two spaced push-pull blocks 3361. Correspondingly, a material frame 10 is placed in storage location A. The material frame 10 has spaced-apart open slots 101 that engage with the corresponding push-pull blocks 3361. Figure 8 As shown, when the material frame 10 is located in storage location A, the storage platform 3 descends to align the push-pull chain 336 with the bottom of the material frame 10 in storage location A. Then, the storage power unit drives the storage slide 333 to move closer to the material frame 10. The push-pull chain 336 is then driven to cycle. During this cycle, the push-pull block 3361 moves upward and enters the outermost open slot 101 of the material frame 10. At this point, the push-pull block 3361 drags the material frame 10 onto the storage slide 333. After dragging a certain distance, another push-pull block 3361 engages with the other open slot 101 in the same manner, thus completely pulling the material frame 10 on storage location A onto the storage slide 333. When storage is required, the reverse action is used.
[0057] Then, the storage and retrieval platform 3 lifts and moves the material frame 10 onto the RGV trolley 4, and then the RGV trolley 4 moves the material frame 10 away, and the storage and retrieval platform 3 performs the next round of storage and retrieval operations.
[0058] Of course, when the RGV trolley 4 is not used for connection, the storage and retrieval platform 3 rises directly to its uppermost limit position. At this time, the storage and retrieval platform 3 is separated from the guide column 6 inside the warehouse, and then the storage and retrieval platform 3 will move with the overhead crane 2. When the overhead crane 2 moves to the exit aisle 5, the storage and retrieval platform 3 descends, and the material frame 10 can be moved out.
[0059] Compared with conventional warehousing systems, this intelligent vertical storage retrieval system has at least the following advantages: 1. The system utilizes the in-vehicle guide column 7 and the in-warehouse guide column 6 to achieve limiting guidance during the lifting and lowering of the storage platform 3, ensuring the stability of the storage platform 3; compared with existing warehousing systems, it has higher stability; and in this embodiment, the storage mechanism 33 is located in the middle of the storage platform, directly acting on the bottom of the material for lifting, so there is no need to customize a material frame, and the force on the lifted material is more reasonable, without the situation of the middle part being suspended and sagging, thus adapting to the storage and retrieval of heavier materials; 2. The suspension point of the storage platform 3 is located outside the center of gravity of the material 8 in storage location A, so the storage platform 3 is not easy to tilt when storing and retrieving material 8, and the stability is higher; 3. The storage mechanism 33 on the storage platform 3 can slide to any position in the Y direction, thus satisfying the storage and retrieval of short materials 8 in multiple storage locations on the same floor of the same aisle.
[0060] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
