Intelligent stereo library , is a new concept in logistics warehousing. application Stereoscopic library Room equipment can end the rationalization of the warehouse high-rise, access automation, and simple operation; Intelligent stereoscopic library is the method with high skill level at that time.
The main body of the intelligent stereoscopic warehouse is composed of shelves, roadway stacking cranes, inbound (outbound) working platforms, and active inbound (outbound) and operational control systems. The rack is a building or structure of steel structure or reinforced concrete structure. The rack is a standard cargo space. The lane stacking crane runs through the lane between the racks to end the storage and picking up operations; WCS system is selected for handling.
Components of intelligent stereo library
1. Rack: steel structure used to store goods. There are mainly two basic methods: welded rack and combined rack;
2. Pallet (cargo box): tools used to carry goods, also known as station tools;
3. Roadway stacker: equipment used for active storage and retrieval of goods. According to the structural method, it can be divided into two types: single column and double column; According to the efficiency method, there are three basic methods: straight, curve and transfer vehicle;
1. Carrier system: the primary peripheral equipment of the stereo warehouse, which is used to transport goods to or from the stacker. There are many kinds of conveyors, such as roller conveyor, chain conveyor, lift table, distribution car, traveling machine, belt conveyor, etc;
2. AGV system: active guided trolley. According to its guiding method, it can be divided into induction guided car and laser guided car;
3. WCS active control system: the active control system that drives the equipment of the active stereo library system. The field bus method is the main control method;
4. WMS information processing system: it is the center of the fully automated stereoscopic database system and can be networked or integrated with other systems (such as ERP system).
Intelligent stereo library planning
The three-dimensional warehouse planning process is generally divided into the following steps:
1、 Collect and discuss the user's raw materials, and understand the policy of the user's arrival. These raw materials include:
1. Be clear about the technological process of the connection between the intelligent stereoscopic library and the upstream, cheap and cheap;
2. Logistics requirements: large Z warehouse keeper entering the warehouse upstream, large Z warehouse out volume transferring to the humble and the required warehouse capacity;
3. Standard parameters of materials: the number of material types, material packaging method, external packaging standard, quantity, storage method, and other characteristics of other materials;
4. Site conditions and environmental requirements of three-dimensional warehouse;
5. User's functional requirements for the warehouse processing system;
6. Other relevant materials and special requirements.
2、 The primary method and related parameters for determining intelligent stereo library
After all the raw materials are collected, relevant parameters required for planning can be calculated based on these first-hand materials, including:
1. Requirements for the total quantity of inbound and outbound of the entire reservoir area, that is, the flow requirements of the warehouse;
2. Appearance standard and weight of goods unit;
3. Number of positions in the warehouse storage area (shelf area);
4. Based on the above three points, it is concluded that the number of rows and rows of shelves in the storage area (shelf factory), the number of lanes and other relevant technical parameters.
3、 Reasonably organize the overall layout and logistics diagram of the intelligent stereoscopic warehouse
Generally speaking, the intelligent stereo library includes: warehousing temporary storage area, inspection area, stacking area, storage area, outbound temporary storage area, pallet temporary storage area, nonconforming product temporary storage area, sundries area, etc. When planning, it is not necessary to plan each of the above areas in the stereoscopic warehouse. You can reasonably differentiate each area and increase or decrease areas according to the user's process characteristics and requirements. At the same time, it is also necessary to reasonably consider the flow of materials, so that the activities of materials can extend in all directions, which will directly affect the talent and power of the intelligent stereo warehouse.
4、 Selection of mechanical equipment types and relevant parameters
goods shelves:
The shelf planning is an important part of the three-dimensional warehouse planning, which directly affects the area and space utilization rate of the three-dimensional warehouse.
Shelving methods: There are many methods for shelving, and the shelves used in the intelligent stereo warehouse generally include: Pallet Racks , bracket shelf, movable shelf, etc. In the planning, it can always be reasonably selected according to the appearance standard, weight and other relevant requirements of the goods unit.
Standard of cargo space: the standard of cargo space depends on the size of the space between the cargo unit and the rack column, crossbeam (bracket). The same pair, to a certain extent, is also affected by the rack structure and other elements.
Stacker:
The stacker is the central equipment of the entire intelligent stereo warehouse, which transfers goods from one place to another after manual operation, semi-active operation or full active operation. It consists of a rack (upper beam, lower beam, column), a horizontal travel organization, a travel organization, a cargo platform, a fork and an electrical control system.
Determination of stacker method: There are various stacker methods, including single track tunnel stacker, double track tunnel stacker, rotary tunnel stacker, single column stacker, double column stacker, etc.
Determination of stacker speed: calculate the horizontal speed, travel speed and fork speed of the stacker according to the flow requirements of the warehouse.
Other parameters and equipment: the positioning method and communication method of the stacker shall be selected according to the warehouse site conditions and user requirements. The stacker can be high or low, depending on the specific situation.
Transportation system:
According to the logistics diagram, reasonably select the type of conveyor, including roller conveyor, chain conveyor, belt conveyor, lifting transfer machine, traveling machine, etc. At the same time, the speed of the transportation system should be reasonably determined according to the instantaneous flow of the warehouse.
Other equipment:
According to the technological process of the warehouse and some special requirements of the user, some auxiliary equipment can be properly added, including handheld terminal, forklift, balance crane, etc.
5、 Plan the functional modules of WCS control system and WMS warehouse processing system
According to the technological process of the warehouse and the requirements of users, reasonably plan the control system and warehouse treatment system. The control system and warehouse handling system generally use modular planning for easy promotion and maintenance.
6、 Simulation and imitation of the whole system
If conditions permit, the whole system can be simulated and imitated, which can make a more intuitive description of the storage and transportation operations in the three-dimensional warehouse, find some problems and deficiencies, and make corresponding corrections to optimize the entire AS/RS system.
7、 Carry out specific planning of equipment and control treatment system
The above is the general process of intelligent stereo library planning. In specific planning, it can be flexibly used in combination with specific conditions.
Investment income of smart stereo library
The advantages of intelligent stereoscopic library are various. For enterprises, they can be reflected in the following aspects:
1. Utilization rate of travel space
The basic starting point of the desire for three-dimensional warehouse in the early stage is the utilization rate of travel space, which can fully save the limited and valuable land. In some western developed countries, the concept of the utilization rate of travel space has a broader and deeper meaning. Land saving has been linked with energy saving, environmental protection and other aspects. Some even regard the utilization rate of space as an important policy to check the rationality and advancement of the system.
The space utilization rate of stereoscopic warehouse is closely connected with its planning. Generally speaking, the space utilization rate of the active elevated warehouse is 2-5 times that of the general flat warehouse, which is quite considerable.
2. It is convenient to form an advanced logistics system and promote the production and processing level of enterprises
The traditional warehouse is only a place for storing goods, and the preservation of goods is its only function, which is a "static storage". The intelligent stereoscopic warehouse uses advanced automated material transfer equipment, which not only enables goods to be actively stored and stored in the warehouse according to demand, but also can be organically connected with production links outside the warehouse. Through the computer processing system and automated material transfer equipment, the warehouse becomes an important link in the production logistics of enterprises. The storage of purchased parts and self restrained parts in the automated warehouse is a link of the whole production. Short term storage is to actively output them to the next process for production at a specified time, and then form an automated logistics system. This is a "dynamic storage" and a significant skill trend in the opening of today's automated warehouse.
Automation is an inevitable trend for warehouse processing. The operation power of intelligent stereoscopic warehouse and the level of active skills can make the logistics power of enterprises move forward significantly. The fundamental skills of stereoscopic warehouse are getting older and older. Now more and more enterprises begin to choose intelligent stereoscopic warehouse. Enterprises can create medium and large stereoscopic libraries according to practical conditions, and also create small and medium-sized automated stereoscopic libraries according to needs.
