Intensive Storage: Planning of Automated Intensive Warehousing System with 4D Shuttle
With the rapid development of the logistics industry, the pallet 4D shuttle three-dimensional warehouse has the advantages of high-efficiency and intensive storage functions, operating costs and systematic and intelligent management in the circulation storage system. It has become one of the mainstream forms of warehousing logistics.
In the imported system, how to reasonably plan the 4D shuttle automated dense storage system is the most critical link, which has an important impact on the system to better empower the enterprise and achieve the important goal of reducing costs and increasing efficiency.
Planning of 4D Shuttle Automated Intensive Warehousing System
The planning of pallet 4D shuttle-type automated dense storage system, including the optimization of storage facility layout, shelf configuration or equipment quantity, and their impact on enterprise investment and construction, minimizes investment costs while ensuring system throughput, and at the same time The cost of later operation should be considered. At present, urban planning and design practitioners are mainly concerned with the division of storage space and the optimization of scheduling paths, while the research on system resource allocation is still blank.
The 4D intelligent dense warehouse is a solution that integrates the characteristics of high-density and multi-deep shuttle racks and intelligent access to automated three-dimensional warehouses. The scheme is more flexible, and the rate of inbound and outbound storage can be improved according to the development needs of users. It can be improved only by adding 4D vehicles and hoists, and a larger storage scheme can be provided according to the complexity of goods specifications to achieve single-deep and double-deep. position, and multi-deep combination mode, real-time information, real-time monitoring, WCS scheduling vehicle operations, real-time monitoring of vehicle coordinate position, speed, lighting and other states.
As the first batch of companies in China to research 4D intensive systems, Nanjing 4D Intelligent Storage Equipment Co., Ltd. has a complete system research and development process starting from 0 for five years. Guided by technological innovation, it has obtained two inventions of core technologies Patents, to provide customers with increasingly optimized high-intensity warehousing automation, information, and intelligent system solutions. The company"s core equipment, the 4D vehicle, adopts mechanical jacking, is thin in thickness, and has an intelligent program, and has realized a parameterized debugging mode. The main track and secondary track structure designed by Nanjing 4D shuttle has better force resistance, saves space and lower cost.
Design and planning of the steel structure of the pallet 4D shuttle three-dimensional warehouse shelf
The difficulty in the design and planning of the steel shelf structure of the pallet 4D shuttle three-dimensional warehouse lies in: the design and optimization of the pallet 4D shuttle steel shelf structure in the warehouse, and the pallet 4D shuttle three-dimensional warehouse is mostly based on existing buildings. And planning, on the basis of fully considering the planning of storage functional areas and meeting the requirements of functional configuration, complete the configuration, planning, design and verification of the pallet 4D shuttle three-dimensional warehouse.
In considering the planning and design of the pallet 4D shuttle three-dimensional warehouse, the types of goods to be stored and the unitized size series, the specifications and dimensions of the pallet 4D shuttle trolley, the height of the building floor in the warehouse area, and the load-bearing and Factors such as uneven ground settlement requirements, construction and operating costs, operating efficiency and reliability configuration of storage and handling equipment, etc., construct a structural model and force system analysis factors for a pallet 4D shuttle high-position steel shelf structure, and a pallet 4D shuttle steel shelf The structure adopts the limit state design method based on probability theory, and uses the partial coefficient design expression for design and calculation, in which the load-bearing members are designed according to the limit state of bearing capacity and the limit state of normal service; , structural form, stress state, connection method, steel material and thickness, working environment and other factors are considered comprehensively, and non-load-bearing components are mainly set according to the structural requirements of steel shelves.
Among them: the column of the pallet 4D shuttle type three-dimensional warehouse shelf is checked according to the two-way bending member, the influence factors of the holes on the front or side of the column need to be considered, and the calculation of the strength design value of the cold bending effect of the column cross-section pass pattern should also be verified. Methods, etc. The content of the checking calculation includes the calculation and checking of the strength, stiffness and stability of the shelf column and its components. The stability checking calculation includes the multi-element requirements such as local buckling, distortion buckling and overall bending-torsion buckling. This is also a point that many engineers and technicians Where it is easy to ignore or not verify, it is also easy to mistake the stability check for the overall stability check, which will bring certain safety hazards to specific engineering projects;
The design and planning of the pallet 4D shuttle steel shelf structure requires detailed analysis of basic data such as customer logistics process requirements, warehouse building structure and its form, and foundation bearing capacity, as well as research on the customer"s logistics operation mode and basic cost composition, and formulation of logistics unit standards. and verification, analysis and comparison of logistics efficiency, configuration of ancillary facilities such as fire protection and lighting, personnel composition, etc., to form a reasonable logistics solution, determine a basically reasonable layout plan or space simulation, and determine structural feature units based on specific project planning information With the structural model, the design and calculation information of the basic structure material selection, node design and optimization, component internal force and deformation control limit of the pallet 4D shuttle steel shelf structure was obtained by manual calculation, and then through finite element parametric modeling and analysis, further Analyze the stress and deformation of specific components, obtain the modal analysis results of the overall structural model, query the analysis results of stress and deformation of components under various working conditions, and perform design checks on the length and slenderness ratio of each component in the model to obtain effective Comparing the internal force and deformation simulation calculation of the basic components with the component information such as compression bending stress ratio and shear stress ratio, and then comparing with the manual calculation conditions, optimizing, checking or test verification, on the premise of ensuring that each component meets the requirements, then Comprehensive analysis and evaluation of the overall stability and load-bearing energy efficiency ratio of the pallet 4D shuttle three-dimensional warehouse to ensure that the steel shelf structure of the pallet 4D shuttle three-dimensional warehouse meets the design requirements.
