　　Basic introduction

　　Automated warehouse

　　Emergence and development of the warehouse is the result after World War II production and technology development. In the early 1950s, the United States emerged using stacking crane bridge warehouse; the late 1950s early 1960s there has been a driver-operated stacker crane warehouse roadway; in 1963 the United States took the lead in the use of computer-controlled high-bay warehouse technology, the establishment of the first computer-controlled warehouse. Since then, the rapid development of automated warehouse in the United States and Europe, and the formation of a specialized discipline. The mid-1960s, Japan began to build warehouse, and the development of faster and faster, becoming one of the largest countries in the world today warehouse with automated.

　　For the development of warehouse and material handling equipment start not later, in 1963 developed into the first bridge stacker cranes (Machinery Department Beijing Materials Handling Research Institute), in 1973 started to develop China's first computer-controlled The automated warehouse (15 meters high, which is responsible for lifting the Department of Mechanical), the library and put into operation in 1980. By 2003, the number of automated warehouse, China has more than 200. Due to the high warehouse space utilization, a strong ability to enter the library, using computer control and management and is conducive to the implementation of modern enterprise management, and other features, has become the logistics and production management indispensable storage technology, more and more corporate attention.

　　Automated warehouse (AS / RS) is a three-dimensional shelf, rail stacker, a storage tray conveyor systems, bar code reading size detection systems, communication systems, automatic control systems, computer monitoring systems, computer management systems, and others such as wire and cable bridge distribution cabinets, trays, adjustable platform, steel platform and other auxiliary equipment consisting of complex automation systems. Use first-class integrated logistics concept, the use of advanced control, bus, communications and information technology, through the coordination of actions carried out over the equipment out of storage operations.

　　Introduction

　　Automated warehouse is an important part of the rapid development of modern logistics system, it has to save space, reduce labor intensity, eliminate errors, improve warehouse automation level and management level, improve the quality of management and operations personnel, reduce outages, effectively reduce the backlog of liquidity, improve logistics efficiency and many other advantages. And plant-level computer management information systems and networking, and automated warehouse is more closely linked to the production line today CIMS (Computer Integrated Manufacturing System) and FMS (flexible manufacturing system) essential key.

　　Beijing Institute of Machinery Industry Automation automated warehousing systems around the development of a variety of automation systems hardware and software products, such as: different types of inventory management software, system simulation software, graphical monitoring and scheduling software, stacker conveyor control software, bar code identification and tracking system, handling robots, palletizing robot, automatically run the car, cargo sorting system, stacker recognition site detection systems, stacker control system, cargo space probe, height detector, conveyor systems, palletizing systems , automatic transmission cars and other products.

　　As one of the costs of saving means of automated warehouse more and more enterprises of all ages, such as Chint Group, Mengniu Dairy and Haier Group and other companies have long used the automated warehouse to improve operational efficiency and achieve economic benefits. As the name suggests, automated warehouse has two main features, the first automated warehouse, this mainly refers to its use of first-class integrated logistics concept, the use of advanced control, bus, communications and information technology, through coordinated action of the device, automatically according to the user's need to complete an orderly designated goods, fast and accurate, and efficient storage of library operations; followed its three-dimensional nature, this mainly refers to the use of this type of storage layers, a dozen or even dozens of layers storey shelf storage unit cargo, cargo inbound and outbound operations with the appropriate material handling equipment, full use of the space to store goods.

　　Automated warehouse is an important part of the rapid development of modern logistics system in land prices, rising raw material and labor costs of the current development of automated warehouse promising. RS's market value has more than 17 billion yuan, according to the China Logistics Information Center, Research and Technology Association, the next few years, automated warehousing market demand will grow 17 percent per year, 2015, the market size of warehouse automation of The more than 32 billion yuan.

　　Automated warehouse classification

　　According to the building in the form of classification fold

　　By architectural forms can be divided into two kinds of integral and separate.

　　(1) monolithic: refers to store shelves in addition to goods, but also as a support structure of the building, forms part of the building that houses the shelf integrated structure, general integral height of 12 meters or more. This warehouse light weight structure, good integrity, seismic good.

　　(2) Separate: Separate the goods stored inside the building shelves independent existence. Separate height of 12 meters or less, but there are 15-20 m in. Applicable to the use of existing buildings as warehouses, factories and warehouses or within a single place to build a high shelf.

　　Classification of the goods in the form of access

　　Access into the form of the goods shelf unit, mobile shelves style and picking shelves style.

　　(1) Shelf unit type: shelf unit type is a common form of the warehouse. First placed in the cargo tray or container, and then into the cargo space on the shelf unit.

　　(2) Mobile shelves formula: mobile electric shelf by shelf type composition, the shelf can be running on the track, the control means controls the shelves by the closure and separation. When the job shelves separate operations can be carried out in the roadway; shelf when not in operation can be closed, leaving only one job roadway to improve space utilization.

　　(3) pick shelf type: picking shelves where sorting mechanism is the core part of the divided roadway within the roadway outside sorting and sorting in two ways. "People arrive before picking" is the former pickers picking stacker multiply arrival grid, grid picking goods from goods required number of the library. "Goods to the people at the election," is there the goods required by the pallet or container stackers to picking area, picking personnel according to the requirements of the bill of lading required goods picked up, and then the rest of the goods back to the place.

　　According to the shelf structure in the form of classification

　　Can be divided into units of goods format, through type, horizontal and vertical rotary rotary.

　　(1) unit of goods warehouse format: similar shelf unit type, roadway takes up an area of ??about one-third.

　　(2) through the formula: In order to improve storage utilization, you can cancel located between the rows of shelves of roadway, the individual shelves merge together to make each layer, the goods through each other in the same column, the formation can be stored more than once cargo unit channel, while at the other end by the library to pick up the crane, become-through warehouse. According to the cargo unit moves within the channel, through the warehouse is divided into gravity-shelf warehouse and warehouse shelves shuttle car. Flow_DST warehouse inventory each channel can only store the same kind of goods, it does not apply to goods in too much quantity is relatively large warehouse. By crane trolley shuttle can carry from one channel to another channel inventory.

　　(3) horizontal rotary warehouse shelves: These warehouses along the ring road itself can run back and forth in the horizontal plane. Each group consists of several separate container shelf composition, using a chain conveyor to link up these containers. There are support rollers underneath each container, the upper part of the guide rollers. When the conveyor operation, the container has a corresponding movement. When the need to extract certain goods, just to give a library instruction at the operating table. When equipped with the necessary container cargo shipments to ports, the shelf is stopped. This shelf for order picking is very suitable for small items. It is simple and practical, full use of space, suitable for operating frequency of less demanding applications.

　　(4) vertical carousel-style warehouse: horizontal carousel-style warehouse similar, but the rotation in the horizontal plane to the vertical plane of rotation. This shelf is particularly suitable for storage of the scroll-like goods, such as carpet, vinyl flooring, film reel, cable reel, etc.

　　Automated warehouse design

　　Each automated warehouse designs are divided into several main stages, each stage has its own goals to be achieved.

　　(A) preparation of the design before

　　Needs analysis (preparation stage) is the first stage in this phase have a question, determine the design goals, and determine the design criteria. Through research designed to collect data, identify various constraints, and its detailed analysis. The main aspects of the design include:

　　1. To understand the construction of the library's on-site conditions, including weather, terrain, geological conditions, ground bearing capacity, wind snow loads, as well as earthquakes and other environmental impact.

　　2. In the automated warehouse of the overall design, mechanical, structural, electrical, civil engineering and other professional intersect, mutual restraint, which requires third-party logistics enterprises must take into account the needs of the professional during the design. For example, the movement precision mechanical structure made according to accuracy and precision of the civil settlement being selected.

　　3. To develop a third-party logistics business investment in storage systems, staffing and other programs in order to determine the scale and mechanized warehouse systems, the degree of automation.

　　4. To condition the TPL warehousing systems related to other aspects of the investigation, for example, the source of the goods, the traffic link library field, goods packaging, cargo handling methods, the final destination of the goods and means of transport, etc. .

　　(B) the selection and planning of the library field

　　Library field selection and arrangement of storage systems for investment in infrastructure, logistics costs, labor conditions have important significance. Taking into account the urban planning, the overall operation of the third-party logistics companies, preferably in automated warehouse near the port, dock, freight stations and other transportation hubs, or close to production or origin of raw materials, or close to the main sales markets, which can greatly reduce the cost of third-party logistics companies. Address whether the library field also has some reasonable impact on environmental protection, urban planning. For example, choose to build traffic restrictions in the business district of automated warehouse, on the one hand and the bustling commercial environment uncoordinated, on the other hand it takes to buy expensive land. Most importantly, due to the traffic restrictions, only a day at midnight to transport goods, which is obviously unreasonable.

　　(C) to determine the form of the warehouse, practices and mechanical equipment parameters

　　Form is determined on the basis of warehouse storage of goods in the investigation. Format is generally used unit cargo warehouses, storage of goods if a single species or small, and large quantities of goods, you can use gravity-shelf or other forms-through warehouse. According to the warehousing process requirements (whole unit or scattered out of storage) to determine the need for stacking order picking, order picking, if needed, and then determine how the job of picking.

　　In order to improve the efficiency of storage handling, should minimize the single mode of operation (ie a single person or a single library library), to maximize the use of composite mode of operation (ie, indirect or return also handling operations). Or the use of a cell carrying two practices goods, which would be: two pairs of forks set the stage stacker, they can stretch respectively, can also stretch the same time, in order to access the goods two cells. Another way is to increase the depth of the shelf, designed as two cargo unit size, but also take appropriate stacker dock widened to double forks to be doubled, so you want to take a fork cargo units when stretched out half as long as the forks can be, while at the same time if you want to take two forks cargo units, as long as the forks fully extended it. In the automated warehouse There is also a frequently used mode of operation, which is called the "free cargo space" approach, which can be close to the storage of goods, especially for the storage of frequent and long, overweight cargo, should try to Cargo and shipping location near work, so do not only shorten the storage time, but also saves transportation costs.

　　Machinery and equipment used in automated warehouse there are many, generally including stacker, continuous conveyor, high top shelf, degree of automation and automatic guided vehicles. During the overall design of the warehouse, according to the size of breed warehouse, cargo warehousing and frequency selection of the most suitable machinery and equipment, and to determine the main parameters of these devices.

　　(D) determine the unit in the form of goods and specifications

　　Because the premise automated warehouse is a unit of handling, so make sure the cargo unit of form, size and weight is a very important issue. It will affect the third party logistics warehouse investment, and will affect the entire storage system equipment, facilities and other issues. Therefore, in order to reasonably determine the form, size and weight of the cargo unit should be based on the results of surveys and statistics, listing all the possible forms of cargo units and specifications, and to make a reasonable choice. For those special shape and size or heavy cargo, can be dealt with separately.

　　After the cargo unit forms and specifications are determined, but also to determine the size of the cargo grid, grid size depend on the size of the cargo of goods around the unit to stay out of the net size and shelf components. Generally these dimensions are based on the actual situation of the net and relevant experience data to determine.

　　(E) to determine the storage capacity (including the buffer zone)

　　Storage capacity is the number of cargo warehouse at the same time accommodate the unit, which is a very important parameter for automated warehouse. Since the inventory cycle is expected to be affected by many outside factors, so inventory wave peaks sometimes dramatically beyond the actual storage capacity of the automated warehouse. In addition, some automated warehouse shelves only consider the capacity of the area, while ignoring the area of ??the buffer zone, resulting in a shortage area buffer zone, so get out of the cargo shelf area, cargo warehouse outside the entrance .

　　Distribution (six) Treasury area and other areas

　　Since the total area is certain, and many third-party logistics companies in the construction of automated warehouse only concerned office, laboratory (including R & D) in the area, but they ignore the warehouse area, thus creating a situation that, in order to meet the storage capacity of needs, had achieved through the development of the space requirements. But the shelves higher procurement costs and operating costs of machinery and equipment is higher. In addition, because the best in the automated warehouse logistics is a straight line, but in the warehouse design often restricted area of ??the plane, causing their logistics circuitous route (s tend to be shaped, and even mesh) This investment will increase the number of unnecessary and cumbersome.

　　Match (seven) personnel and equipment

　　Regardless of the degree of automation automated warehouse of how high, still needs some manual labor during the actual operation, the number of staff to be appropriate. Lack of staff will reduce the efficiency of the warehouse, would cause too much waste. Automated warehouse with a lot of advanced equipment, and therefore require a relatively high quality of personnel, quality of personnel can not keep up, it will also reduce the throughput capacity of the warehouse. Third-party logistics companies need to recruit specialized personnel, and its specialized training.

　　Transmission (eight) system data

　　Since the data transmission path is not smooth or data redundancy and other reasons, can cause slow data transmission system, the phenomenon can not even transfer, the transmission of information to consider the issue of automated warehouse internally and with third-party logistics enterprise management system between the lower .

　　(Ix) the overall operational capability

　　Upstream coordination automated warehouse, the downstream and within each subsystem, there are problems of a barrel effect, ie the shortest piece of wood determines the barrel capacity. Some warehouse with a lot of high-tech products, all kinds of facilities are very complete, but because of the coordination between the various subsystems, compatibility is not good, resulting in overall operational capability much worse than expected.

　　Technical performance folding edit this section

　　Control Systems

　　Advanced technology, the use of field control bus direct means of communication, truly computer monitor is not only control all the decisions, job scheduling and on-site information, such as by stackers, conveyors and other site out of storage devices to communicate with each other coordination is completed.

　　● Each cargo pallet numbers are recorded in a database and computer stacker, the administrator can use comparison functions to compare computer records and stackers in the record, and make changes, modifications can be done automatically and manually .

　　● system software and hardware fully functional, clear user interface, easy operation and maintenance.

　　● Stacker automatic recall the origin function, that regardless of any circumstances, as long as the forks centered and level of functioning properly, in accordance with an order issued by the automatic return to the origin. This means that operators and maintenance personnel can not enter the roadway as possible.

　　● intelligent control system, can achieve real automatic stocktaking function, to avoid a cumbersome manual stocktaking previous work, reducing the work intensity warehouse management staff to ensure that the error rate of the library while the job is zero.

　　Monitoring and management system

　　Monitoring and management systems, including data management, storage management, database management, queries, reports, documents and the library, police, and other monitoring and animation module

　　Superior performance

　　Automated warehouse its advantages are many, for the enterprise, may be reflected in the following aspects:

　　1, improve space utilization

　　Early warehouse conception, the basic starting point is to improve space utilization, saving limited and full of valuable land. In some Western countries, improve space utilization point of view has been more widespread and profound meaning, conservation of land, has been with the energy conservation, environmental protection and other areas more linked. Some even utilization of space systems as an important indicator of a reasonable assessment and advanced to treat.

　　Three-dimensional database space utilization and its planning are closely linked. In general, automated high-bay warehouse space utilization for its 2-5 times the normal level of the library. This is quite impressive.

　　2, to facilitate the formation of advanced logistics system, improve production management level

　　Traditional cargo storage warehouse just a place to save the cargo is its only function is a "static storage." The use of advanced automated warehouse material handling automation equipment, not only make the goods as required automatic access in the warehouse, and can be connected to the warehouse beyond organic production processes, and through the computer management system and automated material handling equipment to make the warehouse to become Production Logistics is an important part. Enterprise purchased parts and production parts made into the automated warehouse storage is a part of the whole production, short-term storage at a specified time in order to automatically output to the next step of production, thus forming an automated logistics system, which is a kind of " Dynamic Storage ", is a clear trend of automated warehouse technology development.

　　Logistics system described above is the entire large enterprise production management systems (from ordering the necessary design and planning, programming and production arrangements, manufacture, assembly, testing, shipping, etc.) of a subsystem, the establishment of logistics systems and large enterprises real-time connectivity between systems is another significant technology trends automated high-bay warehouse development.

　　Our automated warehouse in fewer reasons:

　　1980, since China's first self-developed automated warehouse began production applications in the automotive, chemical, electronics, tobacco and other industries increased year by year. Among them, the most typical is the leading enterprises in China's home appliance warehouse Haier Group International Logistics Center, the warehouse 22 meters high, with 18,056 standard pallet positions, including raw materials and finished two automated logistics system, all to achieve a modern logistics automation and intelligent.

　　Development Status

　　In today's high level of human capital, reduce the costs, automate management has become an important strategic issue corporate research. For the manufacturing industry, logistics costs in its cost share is quite large, the statistics show that logistics costs typically account for more than 50% of the proportion of manufacturing costs, therefore, materials and warehouse management and cost control has become the impact of product market competition The key, and the efficiency of enterprises are inseparable.

　　Because automated warehouse operating efficiency and automation level of technology can make significantly improve the efficiency of enterprise logistics, basic three-dimensional database technology has become more sophisticated, so more and more companies began to use automated warehouse. Many companies not only the construction of large-scale three-dimensional database, also based on the need to build a lot of small and medium-dimensional library automation.

　　According to the "2013-2017 China automation needs and prospects warehouse industry investment analysis report" shows that 2012 is the Chinese year of automated three-dimensional library to get rapid development. In early 2012, due to have started many projects logistics systems, automated library project construction market boomed, according to incomplete statistics, in 2012 the construction of a warehouse with a large-scale construction projects in more than 130 seats, as of 2012 12 months, the national automated three-dimensional library holdings over 1200.

　　Prospective network that, with the continued rapid growth of the national economy continues to improve and the high demand for warehouse automation tobacco, pharmaceuticals, machinery and other industries, the future automated warehouse facing greater market demand. The number of firms in the pharmaceutical industry, for example, according to the National Bureau of Statistics data show that as of 2012, China's industrial output value of more than 20 million in 6075, with 10% of the demand for computing, pharmaceutical industry demand for automated warehouse on There are 607 units, while the current holdings of less than 200 units, the market promising.

　　Warehouse Design

　　With the pace of economic globalization accelerated, the huge potential hidden in the logistics supply chain has attracted people's attention. The logistics center is one of the important supply chain logistics hub. It is accepted and processed downstream users ordering information for large quantities of goods upstream suppliers were centralized storage, processing and other operations, and to carry out the bulk transport downstream facilities and institutions. Directly implementing agencies to implement these functions include:

　　(1) Automatic Storage Equipment (RS)

　　(2) Other shelves (flat pallet flow racks and shelves, etc.)

　　(3) a variety of conveyors (roller conveyors, chain conveyors, belt conveyors, transfer lift, hoist, etc.)

　　(4) all kinds of sorting equipment

　　(5) No trolley (AGV, RGV, LGV)

　　(6) various other auxiliary equipment

　　As an important part of the logistics center, warehouse automation (Automatic Storage & Retrieval System) directly affects the strategies and plans to develop business leaders, command and adjust business operations. Here, briefly talk about its design steps, generally divided into the following steps:

　　First, collect, study the user's original data, clear targets to be achieved by the user, these raw materials include:

　　A clear automated warehouse with upstream and downstream convergence process,

　　2, the logistics requirements: Upstream into the largest member of warehouse storage, the maximum amount of the library to the downstream transport and storage capacity required;

　　3, material specifications: Number of species, material packaging, packaging size, weight, and other ways to save the material properties of other materials;

　　4, warehouse site conditions and environmental requirements;

　　5, the user functional warehouse management system requirements;

　　6, other relevant information and special requirements.

　　Second, determine the main form of automated warehouse and related parameters

　　After all the raw data collected, can be calculated based on these first-hand information of the parameters required for the design, including: ① the entire reservoir area of ??the total storage requirements, namely the warehouse flow requirements: ② cargo units appearance size and weight; ⑤ warehouse storage area (shelf area) the number of positions: ④ combination of these three points to determine the storage area (shelf plant) Rows shelf, number of columns and the number of other relevant technical parameters of the roadway.

　　Third, the rational arrangement of the overall layout of the automated warehouse and logistics map

　　In general, automated warehouse include: storage staging area, inspection area, stacking area, storage area, a library temporary storage area, pallet staging areas, staging areas and debris nonconforming area. When planning, within the warehouse is not necessarily want every one of the above areas are planning to go, according to the user's technical characteristics and requirements of a reasonable division of the regions and changes in the region. At the same time, but also consider the flow of materials and reasonable, so that smooth flow of materials, which will directly affect the ability and efficiency of automated warehouse.

　　Fourth, select the type of machinery and equipment and related parameters

　　Shelf

　　Shelf design is an important part of the design of the warehouse, which directly affects the utilization of warehouse space and space.

　　① shelf forms: There are many forms of the shelf, but with the automated warehouse shelves are generally: the bar shelves, corbels shelves, mobile shelves and so on. Design, can be selected according to the cargo unit of reasonable size, weight, and other relevant factors.

　　② goods grid size: Cargo grid size depends on cargo units and shelves columns, beams gap size (bracket) between the same right, to a certain extent also affected by structural type shelves and other factors.

　　Stacker Folding

　　Stacker is the core of the entire warehouse automation equipment, manual, semi-automatic or fully automatic operation of the cargo handling operation implementation from one place to another. It consists of a rack (on the beam, under beams, columns), the level of travel agencies, promotion agencies, cargo units, forks and electrical control system structure.

　　① stacker forms to determine: stacker variety of forms, including single-track tunnel stacker, stacker-track tunnel, turn roadway heap strains, single column type stacker, double column type stacking machines and more.

　　② stacker speed is determined: according to the traffic requirements of the warehouse, calculate the horizontal speed stacker, improve speed and fork speed.

　　③ other parameters and configuration: data warehouse site conditions and user requirements stacker positioning, communication and other selected. Configuring stacker can be high or low, depending on the specific circumstances.

　　Delivery system

　　According to logistic map, selecting the type of conveyor, including: roller conveyors, chain conveyors, belt conveyors, transfer lift, hoist, etc. At the same time, but also to reasonably determine the speed of delivery systems based on the instantaneous flow of the warehouse.

　　Other equipment

　　According to the warehouse process and some of the special requirements of the user, may be appropriate to increase the number of auxiliary equipment, including: handheld terminals, forklifts, cranes and other balance.

　　Fifth, the preliminary design of the control system and the Warehouse Management System (WMS) for each functional module

　　According to the warehouse process and user requirements, design reasonable control system and warehouse management system (WMS). Control systems and warehouse management systems generally use a modular design for easy upgrades and maintenance.

　　Six simulation of the entire system

　　In the case of conditions, simulation of the entire system can be made more intuitive description of the storage warehouse work and found some problems and deficiencies, and make the appropriate corrections to optimize the entire AS / RS system.

　　Seven, the detailed design of equipment and control management system

　　The general procedure described above is designed for automated warehouse, in the specific design, can be combined with the specific circumstances of flexibility.

　　System Benefits

　　First, save the warehouse area, so that warehouse space to achieve a fully utilized. Due to the use of large-scale automated warehouse storage shelves assembled, coupled with automated management technology makes it easier to find the goods, so the construction of automated warehouse on the smaller footprint than traditional warehouse, but a large space utilization. In developed countries, improve space utilization has been used as a systematic and rational and advanced an important assessment indicators. Today in promoting energy saving, automated warehouse in the area of ??resource conservation has a good effect, but also will make a major trend in the future development of warehousing.

　　Second, automated management to improve the management level of the warehouse. Automated warehouse for goods using computer information accurate information management, reducing errors in the storage of goods may appear to improve the work efficiency. At the same time, three-dimensional automated warehouse implemented in a library storage of goods in transit motorized, safe and reliable transportation, reducing breakage rate of goods, but also to make some special requirements for environmental goods through a specially designed to have a very good save environment, such as toxic, explosive goods, but also reduces the handling of goods at the time might be hurt.

　　Third, the automated warehouse can be formed advanced production chain, promoting the progress of productivity.
