Automatic stereo library Planning and design knowledge base
1、 Basic composition of automated warehouse
1. High rack: steel structure used to store goods. At present, there are mainly two basic forms of welded shelves and combined shelves.
2. Pallet (cargo box): an appliance used to carry goods, also called station appliance.
3. Lane stacker: equipment used to automatically access goods. According to the structural form, it can be divided into two basic forms: single column and double column; According to the service mode, it can be divided into three basic forms: straight road, curve road and transfer car.
4. Conveyor system: Stereoscopic library The main peripheral equipment of is responsible for transporting goods to or from the stacker. There are many kinds of conveyors, such as roller conveyor, chain conveyor, elevator, distribution car, elevator, belt conveyor, etc.
5. AGV system: automatic guided trolley. According to its guidance mode, it can be divided into induction guided car and laser guided car.
6. Automatic control system: the automatic control system that drives the equipment of the automatic stereo warehouse system. At present, the control mode is mainly field bus.
7. Inventory information management system: also called central computer management system. It is the core of the full-automatic stereo library system. At present, typical automated stereoscopic database systems use large database systems (such as ORACLE, SYBASE, etc.) to build typical client/server systems, which can be networked or integrated with other systems (such as ERP systems, etc.).
2、 The role of automated warehouse
1. It can greatly improve the utilization rate of the unit area of the warehouse
2. It can improve labor productivity and reduce labor intensity
3. It can reduce errors in goods processing and information processing
4. Can reasonably and effectively carry out inventory control
5. It can better meet the needs of special storage environment
6. It can improve the function quality and ensure the safe operation of goods in the whole warehousing process
7. Facilitate the overall optimization of the system
3、 Basic facilities of automated warehouse
1. Warehouse building and high shelf
2. Roadway stacking crane: rack, running mechanism, lifting mechanism, fork telescopic mechanism, electrical control equipment
3. Peripheral handling system
4. The key to the establishment of automated stereoscopic warehouse by control system The establishment of automated stereoscopic warehouse requires the integrated construction of the operation process, equipment supporting planning, computer management and monitoring of the entire logistics center, so the following contents must be considered:
Work flow of stereoscopic warehouse
1. Main facilities of stereoscopic warehouse
2. Computer management and monitoring dispatching system
Classification of automated warehouse design
1. Classified by building form: integral type, separated type
2. Classification by warehouse height: high level, middle level and low level
3. Classified by shelf form: unit goods shelf warehouse, through shelf warehouse, rotary shelf warehouse, mobile shelf warehouse
4. Classification by warehouse operation mode: cell warehouse, picking warehouse
5. Automatic warehouses can be divided into pallet automatic warehouses, carton automatic warehouses, and cell picking automatic warehouses according to the types of goods operated and the purpose of operation. ·Pallet automatic warehouse is a storage form in automated warehouse that uses Zduo. It is generally composed of high-rise pallet racks, roadway stacking cranes, conveyor systems, and computer control systems. It has the advantages of high storage density, fast inbound and outbound speed, and high degree of automation. The disadvantage lies in the large investment of the tray automatic warehouse, and it is not economical in the environment of small building storey height. ·Carton automatic library is also called carton automatic library, which is used to deal with product packaging units or other commodity units in the form of boxes. Carton automatic warehouse is suitable for automatic storage of cigarettes, medicine, small household appliances, standard parts and other products, and is suitable for frequent and small amount of inbound and outbound operations. Carton automatic warehouse has the advantages of high automation and is suitable for use in the environment of ordinary building floors. The disadvantages are low storage density and high investment. ·The automatic warehouse for unit picking can handle the picking operation of pallet unit and goods unit at the same time through a fork equipped with a telescopic mechanism and an elevating cab. The value of automated warehouse: efficient supply chain, sales chain collaboration and information transmission greatly reduce the material inventory cycle, improve the turnover speed of funds, and reduce logistics costs and management expenses. As a modern logistics facility, automated three-dimensional warehouse undoubtedly plays an important role in improving the level of logistics warehousing automation. Attachment: High density warehouse technology selection The common high-density warehouse technologies include gravity sliding shelves drive-in rack , drive in/drive out shelf, satellite car drive in shelf, etc. ·The gravity sliding shelf can guarantee 100% first in first out of goods, has good adaptability to the site, and is simple in technology and easy to master. The disadvantage is that the investment is high and the access can only be done in sequence. However, due to the slope and slide, a certain headroom will also be lost. ·The drive in shelf can achieve 90% of the storage capacity utilization rate, but because it does not meet the requirements of first in first out management, it is suitable for inventory scenarios with large quantities and few varieties and low requirements for first in first out. By comparison, the drive in/drive out shelf can meet the first in first out management requirements while retaining the advantages of the drive in shelf, Therefore, it can be applied to the scenarios where there are first in, first out management requirements for large quantities and few varieties, but there are higher specifications and quality requirements for pallets. The satellite car driving into the shelf also has the advantage of flexible use of the origin, which can meet the first in, first out goods management requirements, but the investment is large and the operation is relatively complex.
