With the expansion of production and logistics scale and the improvement of logistics automation, logistics machinery and equipment are more and more widely used in modern production and logistics; Modern production and modern logistics put forward higher requirements for logistics machinery and equipment. With the improvement of modern mechanical equipment design ability and the rapid progress of science and technology, the technical content, knowledge content and cultural content of logistics mechanical equipment have increased sharply. Logistics mechanical equipment is undergoing a great change. In the new century, the technical performance of logistics machinery and equipment will enter a new development stage, and logistics machinery and equipment will achieve greater development
Looking at the development status of logistics machinery and equipment, it can be seen that in order to meet the needs of modern logistics, logistics machinery and equipment have the following development trends:
1. Large scale and high speed
Large scale refers to the increasing capacity, scale and capacity of equipment. High speed refers to the greatly accelerated operation speed, operation speed, identification speed and operation speed of equipment. With the rapid development of modern social economy, the scale of production and logistics is expanding. In order to improve operation efficiency and scale efficiency, the demand for large and high-speed logistics machinery is increasing. The lifting capacity, load capacity, productivity and operation capacity of logistics machinery and equipment are becoming larger and larger, and the working speed is becoming faster and faster.
2. Practicality and lightness
Logistics machinery and equipment is an important material and technical basis for modern and automatic logistics. Logistics machinery and equipment are required to be easy to use, easy to maintain and operate, with excellent durability, fault-free and good economy, as well as high safety and reliability. Therefore, in the future, we will pay more attention to the development of logistics machinery and equipment with good performance, low cost and high reliability. Some logistics machinery and equipment are used in general occasions, and the work is not heavy. This kind of equipment has large batch and wide use. Considering the comprehensive benefits, it can reduce the appearance height, simplify the structure, reduce the cost, and reduce the operation cost of the equipment. This lightweight equipment will have faster development in the future.
3. Specialization and generalization
Logistics is the product of social and economic development, which will inevitably show diversified characteristics with the development of social economy. The characteristics of diversification reflect the diversification of demand for logistics machinery and equipment, so that logistics machinery and equipment have a variety of varieties and Constantly updated. The systematicness and consistency of logistics activities and the speed and mobility of transportation and distribution require some equipment to develop in the direction of specialization, but also require some equipment to develop in the direction of generalization and standardization. Special equipment meets special needs with unique functions and can play a good role. For example, the functions of special cranes such as railway, ship and container will continue to increase, the performance will continue to improve and the adaptability will continue to strengthen; Container ships, bulk carriers, concrete transport vehicles, tank cars and other widely used, low cost. Some general-purpose equipment can also realize the rapid conversion of logistics operations and greatly improve the efficiency of logistics operations. For example, large container trailers can carry all sizes of containers for sea, air and railway transportation. In the future, general-purpose equipment will also be further developed.
4. Automation and intelligence
Combining mechanical technology with electronic technology, applying advanced microelectronics technology, power electronics technology, optical cable technology, hydraulic technology and fuzzy control technology to the mechanical drive and control system, and realizing the automation and intelligence of logistics machinery and equipment will be the development direction in the future. For example, the new generation electrical control device of large and efficient crane has developed into an all electronic digital control system, which is composed of all digital control driving device, programmable controller, fault diagnosis and data management system, digital manipulation given detection and other devices. The application of advanced technology makes the crane more flexible, which improves the comprehensive automation level of single machine. The operation of transportation equipment depends more on instruments, signals and auxiliary driving system, and the degree of intelligence is becoming higher and higher. The development and application of automatic driving system in ocean and air transportation, delivery and pickup trucks in automated warehouse, and intelligent transportation system (ITS) for highway transportation will attract extensive attention from various countries. In addition, with the help of satellite communication technology, the whole process tracking and control of transportation equipment can be carried out to quickly respond to market changes. At the end of 2000, northwest International Telecom Co., Ltd. established a freight vehicle dispatching management system for FAW storage and transportation company. It combines GPS, GIS, GSM and other technologies to realize the whole process tracking and monitoring of goods. The system can effectively avoid the no-load of the vehicle, reasonably and effectively arrange the receiving and shipping time, greatly improve the utilization rate of the vehicle, save the transportation cost, enable the enterprise or cargo owner to understand all the conditions of the goods in transportation, and greatly meet the needs of customers for vehicle safety service, management scheduling and information service. Since its establishment, the system has worked well, played a good effect, provided a foundation for the effective management of logistics, and will be more widely used in the future.
AHV (autonomous handling vehicle) will also be widely used. The shape of AHV is similar to the AGV currently used, but it is equipped with two general-purpose manipulators. When working, it relies on the industrial camera with visual function to judge the position and size of goods. Like people, it can freely carry goods weighing 200-300 kg with manipulators. AHV has the function of cooperative operation. When the transported goods are too long and heavy, more than two ARVs can carry them together, which will greatly reduce the specifications and models of ARV and facilitate management. The joint operation of several AHVs of the same specification can greatly improve their operation capacity.
5. Complete set and systematization
On the basis of single machine automation of logistics machinery and equipment, various logistics machinery and equipment are formed into a logistics machinery and equipment integration system through computer, which is coordinated with the logistics system through the control of the central control room. This kind of logistics mechanical equipment has a high degree of automation and has the function of information processing. It can store, calculate, logic judge and transform all kinds of information detected by the sensor, and then send control instructions to the actuator. This kind of logistics machinery equipment also has a good information input and output interface to realize the complete, accurate and reliable transmission of information in the whole logistics machinery integration system. Through system integration, logistics machinery and equipment can form a good matching and combination of different models, learn from each other's strengths and complement each other's weaknesses, and play a good role. In the future, we will focus on the development of factory production and handling automation system, cargo distribution and distribution system, container handling system, automatic sorting and handling system of goods, etc.
