Description

Technical Field

[0001] This utility model relates to the field of sand casting technology, and in particular to a three-dimensional storage warehouse for large materials. Background Technology

[0002] In the casting equipment industry, the storage and handling of large, heavy-duty workpieces has always been a critical link in the production line. Traditional solutions typically employ heavy-duty stacker crane systems, which achieve three-dimensional storage and retrieval of workpieces through rail-based or aisle-type structures. However, with the increasing size and tonnage of modern castings, traditional stacker cranes have revealed the following technical bottlenecks: Limited load-bearing capacity: When dealing with workpieces weighing more than 10t, the mechanical structure of traditional stacker cranes (such as columns and forks) requires a significant increase in the strength of the steel structure, resulting in bulky equipment, soaring energy consumption, and difficulty in guaranteeing dynamic stability and positioning accuracy. Insufficient flexibility: A single stacker can only serve a fixed aisle. When multiple processes need to be coordinated or urgent orders need to be placed, the system scheduling is rigid and it is difficult to achieve dynamic allocation across regions.

[0003] To address the aforementioned problems, this invention proposes a large-scale automated storage and retrieval system (AS / RS). The AS / RS is divided into two, three, or more layers, each connected by tie beams, enhancing structural stability and load-bearing capacity. It employs a collaborative operation system of "fixed automated lifting roller conveyors + mobile lifting transfer vehicles." The mobile lifting transfer vehicles shuttle between each storage layer and connect with the fixed automated lifting roller conveyors, enabling rapid storage and transfer of materials. This system is particularly suitable for AS / RS storage scenarios where individual items weigh 10-50 tons. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a large-scale automated storage and retrieval system (AS / RS) for large materials. The AS / RS has a single-station load capacity of up to 50 tons, enabling three-dimensional storage of large items and connecting various workstations on the large-item forming production line, effectively improving material handling efficiency. The technical solution adopted by this utility model is as follows: A large-item automated storage and retrieval system, characterized in that it includes: A steel-structured automated warehouse, comprising at least two warehouse layers, with transverse tie beams arranged between adjacent warehouse layers, and each warehouse layer having at least two sub-layers; At least two conveyor lines are laid horizontally within at least two of the storage layers; At least two lifting transfer vehicles move along at least two of the conveyor lines, and the transfer pallets on each of the lifting transfer vehicles are capable of moving up and down between at least two layers of the corresponding warehouse layer; The lifting roller conveyor is arranged vertically in the automated warehouse. The roller pallet on the lifting roller conveyor can be lifted vertically and corresponds to the transfer pallet on at least two lifting transfer vehicles. Several work units are connected to both sides of the automated warehouse.

[0005] Furthermore, lifting roller conveyors are respectively installed on both sides of the conveyor line.

[0006] Furthermore, the bottom of the automated warehouse is lowered to the ground.

[0007] Advantages of this utility model: 1. More stable structure and improved load-bearing capacity of automated storage and retrieval systems: The automated storage and retrieval system is divided into two, three or more layers, with each layer connected by steel tie beams, which enhances the structural stability of the automated storage and retrieval system and improves the load-bearing capacity, realizing the three-dimensional and drawer-style storage of large and heavy materials.

[0008] 2. Improve material transfer efficiency: The system adopts a collaborative operation system of "fixed lifting roller conveyor + mobile lifting transfer vehicle". The mobile lifting transfer vehicle shuttles between each warehouse level and is connected with the fixed three-dimensional lifting roller conveyor. The three-dimensional warehouse connects the various departments of the large-part shaping production line, effectively improving the material transfer efficiency.

[0009] 3. Save workshop space: Thanks to the more stable structure of the automated warehouse, the flow coating and drying equipment (surface drying oven) in the molding line can be arranged on the top floor of the automated warehouse, saving production line space. The multi-layer warehouse can match the various work sections on both sides of the automated warehouse, and the casting station can be flexibly arranged. The casting and cooling fumes are centrally collected and treated for dust removal.

[0010] 4. Can be expanded underground: Heavy-duty automated warehouses with civil engineering requirements can be expanded to two underground levels to store empty sand boxes. At the same time, dust collectors can also be placed on the top of the automated warehouse, so that the flue gas flows upward, which is conducive to the capture and collection of flue gas and saves energy.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] Please see the appendix Figure 1 - Appendix Figure 3 This application proposes a large-item material storage automated warehouse, comprising: a steel-structured automated warehouse 100, the automated warehouse including at least two storage layers 110, with tie beams 120 arranged laterally between adjacent storage layers 110, and each storage layer 110 having at least two sub-layers; at least two conveyor lines 200, respectively laid horizontally within the at least two storage layers 110; the automated warehouse 100 is frame-shaped, with several temporary storage locations arranged sequentially along the conveyor lines 200 in each sub-layer of each storage layer 110 for storing assembly sandboxes; and at least two lifting... A transfer vehicle 300 moves along at least two of the conveyor lines 200. The transfer pallet 310 on each of the lifting transfer vehicles 300 can move up and down between at least two layers of the corresponding storage layer 110. A lifting roller conveyor 400 is arranged vertically within the automated storage and retrieval system 100. The roller conveyor pallet 410 on the lifting roller conveyor 400 can move up and down vertically and corresponds to the transfer pallets 310 on at least two of the lifting transfer vehicles 300. Several work units 500 are respectively connected to both sides of the automated storage and retrieval system 100. Both the lifting transfer vehicle 300 and the lifting roller conveyor 400 are existing technology structures. The structure of the lifting transfer vehicle 300 is similar to that of a lifting platform, and the structure of the lifting roller conveyor 400 is similar to that of a hoist. Their structures will not be described in detail here.

[0017] It should be noted that the steel structure of the automated warehouse in this application is more stable and has a higher load-bearing capacity. The steel structure tie beams installed between adjacent warehouse layers not only enhance the stability of the automated warehouse structure and improve its load-bearing capacity, but also reserve space for the laying of the conveyor line 200, realizing the three-dimensional and drawer-style storage of large and heavy-duty materials with a single workstation load of ≥20t.

[0018] The automated storage and retrieval system 100 of this application can span the entire workshop. Materials enter the automated storage and retrieval system from the transfer pallet 310 on the conveyor line 200 aligned with the workshop floor. The transfer pallet 310 runs along the conveyor line 200 until it aligns with the lifting roller trolley 400. Then, the materials are transferred from the transfer pallet 310 to the roller pallet 410 of the lifting roller trolley 400. The materials are then lifted and lowered by the roller pallet 410 to the height of a certain storage layer 110, and then transferred to the transfer pallet 310 of the lifting transfer vehicle 300 in the corresponding storage layer 110. Finally, the lifting transfer vehicle 300 in the storage layer 110 is transported along the conveyor line 200 in the storage layer 110 to the corresponding position in the storage layer. The materials are lifted and lowered by the transfer pallet 310 to the corresponding layer, and the materials enter the storage location of the layer to complete the entire temporary storage process.

[0019] In one specific implementation method, as shown in the appendix Figure 2 As shown, the automated storage and retrieval system 100 includes three storage layers 110, each of which comprises two levels. In each storage layer 110, a transfer pallet 310 in a corresponding lifting transfer vehicle 300 moves up and down between the two levels. In each lifting roller conveyor 400, a roller conveyor pallet 410 moves up and down between the three storage layers. By utilizing the automated storage and retrieval system 100, the lifting transfer vehicles 300, and the lifting roller conveyors 400, a collaborative operation system of "fixed lifting roller conveyors + mobile lifting transfer vehicles" is achieved. The mobile lifting transfer vehicles shuttle through each storage layer 110 and connect with the fixed automated lifting roller conveyors 400. The automated storage and retrieval system 100 connects to various departments of the large-part shaping production line, effectively improving material handling efficiency.

[0020] See appendix Figure 2 Thanks to the more stable structure of the automated storage and retrieval system, equipment such as flow coating and drying equipment (surface drying ovens) in the molding line can be arranged on the top floor of the automated storage and retrieval system, saving production line space. The multi-layer storage system matches the various work sections on both sides of the automated storage and retrieval system. The casting station can be flexibly arranged. The casting and cooling fumes are centrally collected and treated for dust removal. The stored materials include, but are not limited to, molds, base plates, sand boxes, sand molds to be cast, and casting sand molds.

[0021] In one specific embodiment, the section 500 on the right side of the automated storage unit is configured as a casting section. This section stores the sand molds that have been cast and cooled. The top of this section is enclosed by an exhaust hood and a flue gas channel to centrally extract the cooling flue gas into a dust removal pipe. The casting sand molds are distributed in other layers, corresponding to other sections, facilitating rapid material preparation in other sections.

[0022] In one embodiment, please refer to the appendix. Figure 1 and attached Figure 3Lifting roller conveyors 400 are respectively installed on both sides of the conveyor line 200. By placing the conveyor line 200 in the middle of the automated warehouse 100, the automated warehouse 100 is divided into left and right sub-warehouses. The two lifting roller conveyors 400 are then used to lift and transfer sand boxes to the two sub-warehouses respectively, further improving the flow efficiency. Furthermore, the number of lifting roller conveyors 400 on each side can be configured to be two or more, used in conjunction with different work sections, to further improve the material flow efficiency.

[0023] In one embodiment, the bottom of the automated storage and retrieval system 100 is sunken to the ground. For heavy-duty automated storage and retrieval systems with specific civil engineering requirements, two underground levels can be extended to house empty sand boxes. Simultaneously, a dust collector can be placed on top of the automated storage and retrieval system, allowing flue gas to flow upwards, which is beneficial for flue gas capture and collection, thus saving energy.

[0024] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
