Description

Technical Field

[0001] This utility model relates to the field of automated storage and retrieval systems (AS / RS) for storing materials, and more particularly to a distributed intelligent AS / RS. 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 storage and retrieval method uses a lifting vehicle to lift and transport materials to an inbound / outbound trolley, which then transports the materials out, resulting in a large overall footprint and low space utilization. 2. The lifting vehicle uses four lifting chains to form a lifting system for vertical movement, but this lifting system is prone to swaying. This makes the lifting and transporting of materials unsafe and inaccurate. 3. The lifting vehicle uses a pallet and a support plate on the hopper to cooperate in lifting the materials, therefore a hopper is required on the vertical storage unit. Since the vertical storage unit has many storage locations, each location... A hopper is required, therefore, the vertical storage unit needs to bear the weight of multiple vertical storage units. Simultaneously, because the hopper is supported by pallets at both ends, the middle of the hopper is suspended, making the supporting vertical plate bear a very heavy load. Therefore, if the material in the hopper is heavy, the connection between the supporting vertical plate and the hopper requires extremely high strength. 4. When the lifting vehicle retrieves material, it uses a lateral movement system to move the pallet under the supporting vertical plate, and then the lifting vehicle rises to support the hopper. However, after the pallet is moved laterally under the hopper, the lifting vehicle's center of gravity shifts after lifting the hopper, potentially causing the lifting vehicle to tilt, posing a safety hazard. 5. This device is only suitable for storing and retrieving long materials. For short materials, there will be a row of storage units arranged in multiple locations on both sides of the aisle, making it difficult for this device to retrieve materials from such a row. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a distributed intelligent automated storage and retrieval system (AS / RS) that directly uses overhead cranes and storage / retrieval platforms to deliver materials in storage locations to processing equipment, thus occupying less space and making material storage and retrieval more stable.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a distributed intelligent automated storage and retrieval system (AS / RS), comprising several intelligent AS / RS bodies, each AS / RS body having several aisles, and storage positions for materials on both sides of each aisle. The intelligent AS / RS bodies are arranged side-by-side at intervals, and the space between adjacent intelligent AS / RS bodies constitutes a processing area. The processing area is equipped with processing equipment and a gantry robot for delivering materials to the processing equipment. A ceiling track extending along the X-direction is installed on the top of each intelligent AS / RS body, and a crane is horizontally slidably mounted on the ceiling track. The ceiling track covers the processing area. Below the crane, a storage and retrieval platform that can be raised and lowered along the Z-direction is installed via a suspension and traction mechanism. The storage and retrieval platform is driven by a lifting power device mounted on the crane between the upper and lower limit positions. The overhead crane and the storage / retrieval platform are used to transfer materials from storage locations to the loading platform of the gantry robot. The aisle accommodates the storage / retrieval platform. At least one end of each aisle is provided with a vertically arranged internal guide column. The storage / retrieval platform is provided with a lifting and limiting structure that cooperates with the side wall limiting of the internal guide column. When the storage / retrieval platform is at its upper limit position, the lifting and limiting structure separates from the internal guide column. The overhead crane is also fixed with an internal guide column that is vertically corresponding to the upper end of the internal guide column. When the storage / retrieval platform is at its upper limit position, the lifting and limiting structure cooperates with the internal guide column. The storage / retrieval platform is provided with a storage and retrieval mechanism for storing materials in storage locations on both sides of the aisle or retrieving materials from storage locations. A height detection device for detecting the height of the storage / retrieval platform is also provided between the storage / retrieval platform and the overhead crane.

[0006] 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 provided on the platform body. The center of gravity of the materials in the storage positions on both sides of the aisle is located between the two suspension points on the same end plate. The lifting and limiting structure is provided on the end plate.

[0007] As a preferred embodiment, the lifting and limiting structure includes at least four side limiting wheels rotatably mounted on the end plate of the storage and retrieval platform. The rotation center of the side limiting wheels extends in the Y direction, and 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.

[0008] As a preferred embodiment, the lifting and limiting structure further includes at least one intermediate limiting wheel rotatably mounted on the end plate 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. The intermediate limiting wheel rolls in cooperation with the inner surface of the guide column inside the warehouse and the guide column inside the vehicle.

[0009] As a preferred embodiment, a base is slidably mounted on the platform body along the Y direction, and a Y-sliding power device is provided on the platform body to drive the base to slide along the Y direction. Correspondingly, there are at least two storage locations on the same side and at the same height in the same alleyway, arranged along the Y direction, and the storage and retrieval mechanism is fixed on the base.

[0010] As a preferred embodiment, the storage and retrieval mechanism is a telescopic fork or a push-pull storage and retrieval mechanism. The push-pull storage and retrieval mechanism includes a storage and retrieval slide mounted on a base 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.

[0011] 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.

[0012] As a preferred embodiment, the processing equipment is a cutting machine, and the material is a profile, bar, or pipe.

[0013] As a preferred embodiment, the suspension point on the end plate is a hanging ring or a movable pulley, and the suspension traction mechanism is a wire rope traction mechanism and a chain traction mechanism.

[0014] As a preferred embodiment, the intelligent automated warehouse body has an inlet at one end or an inlet on one side of one of the aisles, and an inlet railcar is connected to the inlet.

[0015] After adopting the above technical solution, the effect of this utility model is as follows: A distributed intelligent automated storage and retrieval system (AS / RS) includes several intelligent AS / RS bodies, each with several aisles. Each aisle has storage spaces on both sides for storing materials. The intelligent AS / RS bodies are arranged side-by-side at intervals, and the space between adjacent intelligent AS / RS bodies constitutes a processing area. The processing area is equipped with processing equipment and a gantry robot that delivers materials to the processing equipment. Each intelligent AS / RS body has a top rail extending along the X-direction, and a crane is horizontally slidably mounted on the top rail, covering the processing area. A storage and retrieval platform, movable in the Z-direction, is installed below the overhead crane via a suspension and traction mechanism. Driven by a lifting power unit mounted on the overhead crane, the platform moves between the upper and lower limit positions. The overhead crane and the storage and retrieval platform are used to transfer materials from the storage location to the loading platform of the gantry robot. The aisle accommodates the storage and retrieval platform, and each aisle has a vertically installed internal guide column at at least one end. The storage and retrieval platform is equipped with a lifting and limiting structure that cooperates with the side wall limiting of the internal guide column. When the storage and retrieval platform is at the upper limit position, the lifting and limiting structure separates from the internal guide column. The overhead crane is also fixed with internal guide columns that vertically correspond to the upper ends of the guide columns inside the warehouse. When the storage and retrieval platform is at its upper limit position, the lifting and limiting structure cooperates with the internal guide columns for limiting. 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 installed between the storage and retrieval platform and the overhead crane. Therefore, this intelligent vertical warehouse uses the overhead crane to drive the storage and retrieval platform to slide on the overhead rail, so the storage and retrieval platform can move between various aisles and processing areas. When loading is required, the overhead crane first moves the storage and retrieval platform... The platform moves above the corresponding aisle, and then the suspension traction mechanism lowers the storage / retrieval platform. A height detection device monitors the platform's descent position. Once the platform reaches the designated height, it aligns with the material in the corresponding storage location. During descent, the lifting limit structure engages with the guide columns inside the storage area to ensure stability and prevent swaying. After retrieving the material from the corresponding location, the platform rises and separates from the guide columns, continuing its guiding and limiting engagement with the guide columns inside the crane. This ensures stability and prevents swaying as the crane moves. Once the crane moves the platform above the corresponding processing area, it descends to place the material on the gantry robot's loading platform, and then rises again for subsequent storage / retrieval operations. The gantry robot can deliver materials from the loading platform to the processing equipment for processing. The entire intelligent automated warehouse makes full use of space, directly and accurately and smoothly delivering materials from the storage location to the loading platform of the gantry robot, eliminating the need for other transfer trolleys. The overall operation process is simpler and costs are reduced.

[0016] 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, and the storage and retrieval mechanism is set on the platform body, the center of gravity of the materials in the storage positions on both sides of the aisle is located between the two suspension points on the same end plate, and the lifting and limiting structure is set on the end plate, therefore, after the storage and retrieval platform is suspended, when the storage and retrieval mechanism retrieves the materials in the storage positions, the center of gravity of the materials is always between the suspension points, so the storage and retrieval platform is not easy to tilt, and the overall force distribution is more reasonable.

[0017] Furthermore, the lifting and limiting structure includes at least four side limiting wheels rotatably mounted on the end plate of the storage and retrieval platform. The rotation center of each side limiting wheel extends in the Y direction, and 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. The lifting and limiting structure also includes at least one intermediate limiting wheel rotatably mounted on the end plate of the storage and retrieval platform. The rotation center of each intermediate limiting wheel extends in the X direction, and the intermediate limiting wheel is located in the vertical limiting channel. The intermediate limiting wheel rolls in cooperation with the inner surfaces of the guide pillars inside the storage area and the guide pillars inside the vehicle. Therefore, by using the intermediate limiting wheel and the side limiting wheels to limit and guide the guide pillars inside the storage area and the guide pillars inside the vehicle, the storage and retrieval platform can be constrained while ensuring smooth lifting and lowering of the platform.

[0018] Furthermore, since a base is slidably mounted on the platform body along the Y direction, and a Y-sliding power device is provided on the platform body to drive the base to slide along the Y direction, correspondingly, there are at least two storage locations on the same side and at the same height in the same alleyway, arranged along the Y direction. The storage and retrieval mechanism is fixed on the base. Therefore, the base can be driven to slide along the Y direction by the Y-sliding power device. In this way, the storage and retrieval mechanism can change its position along the Y direction, thereby adapting to the storage and retrieval requirements of multiple storage locations at the same height. Therefore, it can be adapted to the storage and retrieval of materials of different lengths.

[0019] Furthermore, since the lower end of the vehicle guide column is provided with a downwardly tapering lower guide section, and the upper end of the corresponding warehouse guide column is provided with an upwardly tapering upper guide section, and the lower guide section and the upper guide section are directly connected to each other, the upper guide section and the lower guide section can be used to facilitate the side limit wheel and the middle limit wheel to transition better between the vehicle guide column and the warehouse guide column.

[0020] Furthermore, since the suspension points on the end plate are hanging rings or movable pulleys, and the suspension and traction mechanisms are wire rope traction mechanisms and chain traction mechanisms, the force on the platform body can be reduced when using movable pulleys.

[0021] Furthermore, since the intelligent automated storage and retrieval system has an inlet at one end or an inlet on one side of one of the aisles, and an inlet railcar is connected to the inlet, the inlet railcar can be used to conveniently deliver materials into the inlet. Then, the overhead crane can move the storage and retrieval platform into the inlet to connect with the inlet railcar to receive the materials and then deliver them to the designated storage location, thus facilitating the replenishment of materials into the intelligent automated storage and retrieval system.

[0035] The present invention will be further described in detail below through specific embodiments.

[0036] like Figures 1 to 3 As shown, a distributed intelligent automated warehouse includes several intelligent warehouse bodies 1, each intelligent warehouse body 1 is provided with several aisles 2, wherein the intelligent warehouse body 1 is formed by welding and fixing the profiles 101 together, and each aisle 2 on the intelligent warehouse has storage space 102 for storing materials 9 on both sides. The intelligent warehouse bodies 1 are arranged side by side at intervals, and the space between adjacent intelligent warehouse bodies 1 constitutes a processing area 11.

[0037] The processing area 11 is equipped with processing equipment and a gantry robot 6 that delivers materials 9 to the processing equipment. In this embodiment, the processing equipment is selected according to actual processing needs. For example, when the intelligent vertical storage contains pipes, bars, or profiles 101, the processing equipment can be a cutting machine, chamfering machine, drilling machine, etc. In this embodiment, a laser cutting machine 5 is selected. The gantry robot 6 is used to deliver materials 9 from the loading platform 7 to the laser cutting machine 5. One end of the laser cutting machine 5 is equipped with a unloading cart, and then the cut materials 9 are transferred and collected by a robotic arm.

[0038] Each intelligent automated storage and retrieval system (AS / RS) body 1 is equipped with a top rail 104 extending in the X direction. The top rail 104 can be directly fixed to the top of the frame of the intelligent AS / RS body 1, or it can be set up as a separate rack.

[0039] A crane 4 is horizontally slidably mounted on the overhead rail 104, which covers the processing area 11, so that the crane 4 can move above any processing area 11.

[0040] In this embodiment, as Figure 4 As shown, the overhead crane 4 in this embodiment includes a crane frame 41. The crane frame 41 is equipped with a platform window 42 for accommodating the lifting and lowering of the storage / retrieval platform 3. The crane frame 41 is also equipped with a traveling mechanism 45 for the overhead rail 104 to travel on. When the storage / retrieval platform 3 is within the platform window 42 and higher than the intelligent automated storage and retrieval system (AS / RS) body 1, the storage / retrieval platform 3 leaves the AS / RS body and can then move with the crane 4 into any aisle 2. The traveling mechanism 45 on the crane 4 is a conventional structure and will not be described in detail here.

[0041] Below the overhead crane 4, 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 4 to rise and fall between the upper limit position and the lower limit position. The overhead crane 4 and the storage and retrieval platform 3 are used to transfer the material 9 on the storage location 102 to the loading platform 7 of the gantry robot 6.

[0042] In this embodiment, the suspension and pulling mechanism is either a wire rope pulling mechanism or a chain pulling mechanism. Preferably, a wire rope pulling mechanism is used in this embodiment. Correspondingly, a winding power device 43 for winding the wire rope is provided on the overhead crane frame 41. This winding power device 43 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 4 is also equipped with wire guide wheels to facilitate the winding and unwinding of the wire rope. Of course, as... Figure 11 As shown, the hanging ring 36 at the suspension point can also be a movable pulley 310. The movable pulley 310 is embedded in the end plate 32 at both ends of the storage and retrieval platform 3 and can be rotated and installed. When pulled by the wire rope traction mechanism, the traction force during suspension can be saved.

[0043] The passageway 2 accommodates the storage and retrieval platform 3. Each passageway 2 has a vertically arranged in-warehouse guide column 103 at at least one end. In this preferred embodiment, both ends of the passageway 2 are provided with in-warehouse guide columns 103. The guide columns of the storage position 102 are welded to the intelligent vertical warehouse body 1 and are vertically arranged. 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 column 103. When the storage and retrieval platform 3 is in the upper limit position, the lifting and limiting structure separates from the in-warehouse guide column 103. The overhead crane 4 is also fixed with an in-vehicle guide column 44 that is vertically corresponding to the upper end of the guide column 103 in the warehouse. When the storage and retrieval platform 3 is in the upper limit position, the lifting limit structure cooperates with the in-vehicle guide column 44 for limiting. The storage and retrieval platform 3 is provided with a storage and retrieval mechanism 33 for storing materials 9 in the warehouse positions 102 on both sides of the aisle 2 or for retrieving materials 9 from the warehouse positions 102. 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 4.

[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 4, and a reference plate is installed on the overhead crane 4 or the access platform 3, so as to determine the height of the access platform 3 by laser rangefinder.

[0045] like Figure 6 As shown, 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. The suspension points are connected to the suspension traction mechanism. The storage and retrieval mechanism 33 is provided on the platform body 31. The center of gravity of the material 9 on the storage positions 102 on both sides of the aisle 2 is located between the two suspension points on the same end plate 32. The lifting and limiting structure is provided on the end plate 32. Figure 6 In this embodiment, the storage and retrieval mechanism 33 is a telescopic fork 332, which is fixed to 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 102 at the same height on both sides of the same aisle 2. For example, some long pipes, bars, or profiles 101 are directly stored in one storage location 102 of the aisle 2. At this time, the telescopic fork 332 can slide in both directions. The telescopic fork 332 is located in the middle position, and the distance between the support arms of the forks is relatively wide, so that the material 9 can be stably supported. At the same time, the center of gravity of the material 9 on the storage location 102 is between two suspension points on the same end plate 32. When the telescopic forks 332 are inserted under the material 9, the storage platform 3 rises to lift the material 98. Since the center of the material 9 is still between the suspension points when it is lifted, the storage platform 3 is more stable when storing and retrieving the material 9. By using the telescopic forks 332 for storage and retrieval, the material frame 10 can be used or not.

[0046] like Figure 6As shown, 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, and the side limiting wheels 34 form a vertical limiting channel that facilitates the passage of the guide pillar 103 in the storage area and the guide pillar 44 in the vehicle. The side limiting wheels 34 roll in cooperation with the opposite side walls of the guide pillar 103 in the storage area and the guide pillar 44 in the vehicle. The lifting and limiting structure also includes at least one intermediate limiting wheel 35 rotatably mounted on the end plate 32 of the storage and retrieval platform 3. The rotation center of each intermediate limiting wheel 35 extends parallel to the X direction, and the intermediate limiting wheel 35 is located in the vertical limiting channel. The intermediate limiting wheel 35 rolls in cooperation with the inner surfaces of the guide pillar 103 in the storage area and the guide pillar 44 in the vehicle.

[0047] In this way, when the platform body 31 is raised or lowered vertically, the four side limiting wheels 34 and the two middle limiting wheels 35 roll in cooperation with the side of the guide column 103 in the warehouse or the guide column 44 in the vehicle, thereby achieving the guiding and limiting of the platform body 31. The platform body 31 is less likely to shake when it is raised or lowered, thus improving its stability.

[0048] like Figure 7 As shown, a base 331 is slidably mounted on the platform body 31 along the Y direction. A Y-sliding power device 37 is provided on the platform body 31 to drive the base 331 to slide along the Y direction. Correspondingly, there are at least two storage locations 102 on the same side and at the same height in the same alleyway 2, arranged along the Y direction. The storage and retrieval mechanism 33 is fixed on the base 331. Figure 7 In this design, the platform body 31 is provided with a Y-guide rail 39 extending along the Y direction, and the base 331 is slidably mounted on the Y-guide rail 39 along the Y direction and driven by a Y-sliding power device 37. The Y-sliding power device 37 is a servo motor, and drives the base 331 to slide via a drive chain 38 or a synchronous belt extending along the Y direction. Since the base 331 can slide in the Y direction, it can drive the storage and retrieval mechanism 33 to slide in the Y direction. Therefore, when there are at least two storage locations 102 at the same height on the same side of the same aisle 2 and arranged along the Y direction, the storage and retrieval mechanism 33 can select any storage location 102 for material 9 storage and retrieval. Figure 7 The storage and retrieval mechanism 33 still uses telescopic forks 332, but compared to Figure 6 In the proposed design, the telescopic forks 332 can move in the Y direction.

[0049] like Figures 8 to 10As shown in the attached figure, the access mechanism 33 is a push-pull type access mechanism. The push-pull type access mechanism 33 includes an access slide 333 slidably mounted on a base 331 along the X direction. An access power device for driving the access slide 333 to slide is mounted on the base 331. The access power device also uses an access servo motor and drives the access slide 333 to slide along the X direction via a gear 334 and rack 335 mechanism. The gear 334 is rotatably mounted on the access slide 333 via a transmission shaft, while the rack 335 is fixed to the base 331.

[0050] At least two parallel, cyclically running push-pull chains 336 are installed on the storage slide 333. The push-pull chains 336 are driven by a push-pull power device 337 to run in both directions. Each push-pull chain 336 has two push-pull blocks 3361 spaced apart. Correspondingly, a material frame 10 is placed on the storage position 102. The material frame 10 has open slots 1001 spaced apart that engage with the corresponding push-pull blocks 3361. When the push-pull blocks 3361 on the push-pull chain 336 are running in cycles, they engage with the open slots 1001.

[0051] Similarly, the push-pull power device 337 is a motor, which also drives the push-pull chain 336 to run in both directions via a synchronous belt transmission mechanism. A synchronous pulley is fixed on the chain shaft 338 of the push-pull chain 336, and synchronous belt transmission is achieved between the chain and the push-pull power device 337. Each push-pull chain 336 has two push-pull blocks 3361 spaced apart. Correspondingly, a material frame 10 needs to be placed in the storage location 102. The material frame 10 is provided with spaced-apart open slots 1001 that engage with the corresponding push-pull blocks 3361. Figure 8 As shown, when the material frame 10 is located in storage position 102, the storage and retrieval platform 3 descends to align the push-pull chain 336 with the bottom of the material frame 10 on storage position 102. Then, the storage and retrieval power device drives the storage and retrieval 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 from bottom to top and enters the outermost open slot 1001 of the material frame 10. At this point, the push-pull block 3361 drags the material frame 10 onto the storage and retrieval slide 333. After dragging a certain distance, another push-pull block 3361 engages with the other open slot 1001 in the same manner, thus completely pulling the material frame 10 on storage position 102 onto the storage and retrieval slide 333. When storage is required, the reverse action is used.

[0052] like Figure 4As shown, the lower end of the in-vehicle guide column 44 is provided with a downwardly tapering lower guide section, and the upper end of the corresponding in-vehicle guide column 103 is provided with an upwardly tapering upper guide section 1031. The lower guide section and the upper guide section 1031 are directly opposite each other. In this way, the side limiting wheel 34 and the middle limiting wheel 35 can enter the in-vehicle guide column 103 and the in-vehicle guide column 44 more smoothly.

[0053] like Figure 1 and Figure 2 As shown, the intelligent automated storage and retrieval system 1 has an entry point at one end or on one side of one of the aisles 2, and an entry railcar 8 is connected to the entry point. The entry railcar 8 can enter the warehouse from the middle, for example... Figure 2 In the intelligent automated warehouse 1, one of the aisles 2 serves as the inlet, and materials 9 are put into storage from one side in the Y direction.

[0054] Of course, the storage can also be carried out at the end of the intelligent automated storage and retrieval system 1. For example, the storage can be carried out at the end of the intelligent automated storage and retrieval system 1 in the X direction. Similarly, the overhead crane 4 can be moved to the storage position 102 to connect the material 9 when it is stored.

[0055] The operation flow of this embodiment is as follows: 1. The material 9 is sent into the inlet of the intelligent automated storage and retrieval system 1 using the inlet railcar 8. The overhead crane 4 moves the storage and retrieval platform 3 to the inlet. The storage and retrieval mechanism 33 on the storage and retrieval platform 3 is activated. When the telescopic forks 332 are used, the forks only need to be extended under the material 9. Then the storage and retrieval platform 3 rises to support and lift the material 9. Then the forks retract to move the material 9 onto the storage and retrieval platform 3. When the push-pull storage and retrieval mechanism 33 is used, the push-pull storage and retrieval mechanism 33 descends under the material frame 10. The storage and retrieval slide 333 extends and pulls the material frame 10 into the storage and retrieval platform 10 through the push-pull chain 336. The slide 333 is placed on the slide block 333, and then the slide block 333 is reset. Then the storage and retrieval platform 3 is driven to rise and detach from the intelligent vertical warehouse body 1. The side limit wheel 34 and the middle limit wheel 35 of the storage and retrieval platform 3 are guided and limited by the guide column 103 inside the warehouse and the guide column 44 inside the vehicle. Then the overhead crane 4 drives the storage and retrieval platform 3 to move to the aisle 2 where the target warehouse location 102 is located. After the storage and retrieval platform 3 descends to the designated height, the storage and retrieval mechanism 33 moves the material 9 to the corresponding warehouse location 102. The above actions are repeated to store all the required materials 9 in the designated warehouse location 102 and record the type of materials 9 stored in the warehouse location 102.

[0056] 2. The overhead crane 4 moves above the corresponding aisle 2, the storage and retrieval platform 3 descends to retrieve the material 9 from the corresponding storage location 102, then the storage and retrieval platform 3 rises onto the overhead crane 4, and moves with the overhead crane 4 to the designated processing area 11. The storage and retrieval platform 3 then descends directly to the loading platform 7, and the storage and retrieval mechanism 33 places the material 9 on the loading platform 7. After that, the storage and retrieval platform 3 moves away to perform other storage and retrieval operations.

[0057] 3. The gantry robot delivers the material 9 from the loading platform 7 to the processing equipment for processing, such as using a laser cutting machine 5 for cutting. After the material 9 is cut, it is transferred by a robotic arm.

[0058] Compared with conventional automated storage and retrieval systems (AS / RS), this distributed intelligent AS / RS has at least the following advantages: 1. In this embodiment, the intelligent AS / RS has optimized its layout. By using the overhead crane 4 and the storage and retrieval platform 3, materials 9 on any storage location 102 on both sides of the aisle 2 can be directly stored and retrieved and then sent to the processing equipment. This simplifies the material feeding and conveying process. Compared with the conventional method of requiring an outbound material feeding trolley to feed materials between the intelligent AS / RS and the processing equipment, this embodiment omits the outbound material feeding trolley, reducing costs and simplifying the process. 2. This distributed intelligent automated storage and retrieval system utilizes the in-vehicle guide column 44 and the in-warehouse guide column 103 to achieve limiting guidance during the lifting and lowering of the storage and retrieval platform 3, ensuring the stability of the storage and retrieval platform 3. Compared with the existing structure, it has higher stability. Furthermore, in this embodiment, the storage and retrieval mechanism 33 is located in the middle of the storage and retrieval platform 3, directly acting on the bottom of the material 9 for lifting. After lifting, the material 9 has good stability and can also be used for storage and retrieval in the absence of a material frame 10. The force on the lifted material 9 is more reasonable, and there will be no situation where the middle part is suspended and drooping. Therefore, it can adapt to the storage and retrieval of heavier materials 9. 3. The suspension point of the storage and retrieval platform 3 is located outside the center of gravity of the material 9 in the storage position 102. In this way, the storage and retrieval platform 3 is not easy to tilt when storing and retrieving the material 9, and the stability is higher. 4. The storage and retrieval mechanism 33 on the storage and retrieval platform 3 can slide to any position in the Y direction. Therefore, it can meet the storage and retrieval needs of short materials 9 in multiple storage positions 102 on the same floor of the same lane 2.

[0059] 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.
