Talking about Automatic stereo library Shopping guide for
automation Stereoscopic library Because it has many advantages, such as saving land, improving storage efficiency, improving the timeliness and accuracy of warehouse management, it has been widely used. Due to space constraints, this article will not repeat the form and classification of the automated stereoscopic warehouse, but mainly introduce the planning and purchase of automated stereoscopic warehouse.
1、 Main design principles
A good automated warehouse system generally follows the following principles:
1. High performance and low cost of the system (high cost performance ratio);
2. Try to use simple and suitable equipment, use less equipment Z, and simplify the entire logistics system;
3. Less article handling times Z, high overall operation efficiency Z;
4. Fully consider the safety of personnel and system;
5. High degree of unmanned, try to reduce manual intervention;
6. Meet relevant national and industrial standards, and try to use standard parts and systems;
7. Simple and convenient operation and maintenance;
8. Reduce use and maintenance costs;
9. High service quality of system integrator;
10. High flexibility, easy to improve, expand and upgrade the system;
In addition, there are requirements for reducing energy consumption and environmental protection.
In specific situations, some of the above principles may affect or even restrict each other. In order to make a good design, the designers must have a solid theoretical basis, rich practical experience and in-depth understanding of the requirements of the buyer, and make trade-offs to revise and supplement the relevant principles.
2、 Main performance parameters
1. Inventory capacity: the capacity of the three-dimensional warehouse, including the total amount of all items to be stored and temporarily stored in the three-dimensional warehouse;
2. System working ability: the ability of warehouse logistics system to issue, receive and operate;
3. Information processing: the information processing capability of the stereoscopic warehouse, including information collection, information processing, information query, information communication, and even business information processing capabilities;
4. Peripheral logistics processing: how to unload, inspect, assemble and transport the goods to the lane crossing of the high-rise shelf, and how to disassemble, merge, pick, transport and load the goods after taking them out of the high-rise shelf;
5. Human machine connection ability: the connection between the operator and the system, human-machine interface, information entry, handling of nonconforming products, entering the automatic handling line, etc;
3、 Planning and design steps
In order to complete the design of an automated stereo library, relevant experienced technicians should be organized to carry out the following work:
1. Demand analysis: summarize, analyze and sort out the requirements and data proposed by the Buyer, determine the design objectives and standards, and carefully study the feasibility, schedule, organizational measures and other factors affecting the design;
2. Determine the form and specification of cargo unit: determine the reasonable form and specification of the unit according to the survey and statistical results and comprehensive consideration of various factors. This step is very important because it is the basis for the design and implementation of the following steps;
3. Determine the form, operation mode and mechanical equipment parameters of automated warehouse: there are many forms of three-dimensional warehouse, and generally the form of unit goods is used. Determine the operation mode according to the process requirements, select or design appropriate logistics handling equipment, and determine their parameters;
4. Establish a model: determine the number, size, location, operating range and other layout of logistics equipment in the warehouse, as well as the connection between them;
5. Determine the process flow and simulate the working capacity of the warehouse system: determine the warehouse access mode and process flow. Through logistics simulation software and calculation, the data of operation cycle and capacity of logistics system are obtained;
According to the results of simulation calculation, adjust all relevant parameters and configurations (repeat steps ②~⑤) until the requirements are met.
6. Determine the control mode and warehouse management mode: there are many control modes, mainly based on the above equipment to select a reasonable mode and meet the needs of the buyer. Generally, warehouse management is carried out through the computer information system to determine which business departments, computer networks, data processing methods, interfaces and operations between them are involved;
7. Determine the technical parameters and configuration of the automation system: determine the configuration and technical parameters of the automation equipment according to the design, for example, what kind of computer and controller to choose;
8. Determine boundary conditions: define the scope of work of all parties concerned, the working interface and the connection between interfaces;
9. Put forward requirements for civil engineering and public works: put forward requirements for foundation bearing, power supply, lighting, ventilation and heating, water supply and drainage, alarm, temperature and humidity, cleanliness, etc;
10. Form a complete technical scheme of the system: consider other relevant factors, discuss with the Buyer, make comprehensive adjustment scheme, and form a feasible preliminary technical scheme after Z;
4、 Procurement requirements
The purchaser shall specify the specific requirements for the equipment in advance, as listed in Section II.
1. Functional requirements: warehousing, outbound, transportation, information processing, personnel operation and maintenance, etc;
2. Requirements for degree of automation: manual, semi-automatic, full-automatic, etc;
3. Auxiliary requirements: video monitoring, temperature and humidity measurement and control, access control, manual vehicle handling, etc;
4. Scope of work and procurement of the system: In order to complete the procurement of the stereoscopic warehouse, the buyer and the seller must sign a contract, so the scope of work of both parties must be clear, and the scope of supply of the seller must be clear;
5. Boundary conditions: site conditions (length, width, height), power supply, ground foundation, etc;
6. Requirements for construction period: The shorter the construction period is, the better from the perspective of the purchaser. However, there is always a process. Moreover, it is a multi-disciplinary warehouse with multiple disciplines, multiple types of work and a certain scale. After signing the contract, it will go through many links such as design, procurement, manufacturing, processing, assembly, control and management of software development, inspection, packaging, transportation, on-site installation, commissioning, acceptance and training, which is too short to ensure high quality;
7. Service requirements: pre-sales, in sales, after-sales, training, warranty, system upgrade problems, service response time, etc;
5、 Several problems needing attention
1. Do not excessively pursue the high performance of a single device (type) while ignoring the performance of the overall system;
2. Various requirements should be appropriate, the key is to meet their own use requirements. Too low requirements can not meet the use needs, and too high requirements may lead to high system cost, low reliability, difficult implementation, inconvenient maintenance or poor flexibility;
3. The determination of construction period shall be practical and realistic. Too short construction period may cause the decline of system quality, or it is impossible to deliver on time;
4. The routine maintenance of the system is very important. Just like the way we maintain cars, the system should be maintained frequently to keep the system in good working condition, extend the service life of the system, and find out the hidden trouble in time;
5. In order to use the automated stereoscopic warehouse well, high-quality management and maintenance personnel are required, and corresponding supporting measures are required;
