With the intervention of control and drive technology, servo technology and the concept of digital-to-analog conversion, the packaging machinery market has undergone several rounds of change. At present, China has become the world’s largest producer and exporter of commodities. At the same time, the global attention is also focused on the fastest growing, largest and most promising Chinese packaging market.
Flexibility in production - making product packaging more flexible Currently, major companies are adapting to fierce competition in the market, and the cycle of product replacement is getting shorter and shorter. Such as cosmetic production, generally can achieve a change in three years, even a change in a quarter, while the demand is relatively large (such as packaging equipment used in wooden packaging boxes), so the flexibility and flexibility of the packaging machinery is proposed very high The requirement is that the life of packaging machinery is much longer than the life cycle of the product. The concept of flexibility can be mainly considered from these three aspects: the flexibility of quantity, flexibility of construction, and flexibility of supply.
Specifically speaking, to make the packaging machinery have good flexibility and flexibility, and to improve the degree of automation, we need to use microcomputer technology, functional module technology. For example, in a food packaging machine, combining different units on the basis of one machine, using multiple feed ports and multiple different folding packaging forms, different types of products can be packaged at the same time. Multiple robots are operated under the supervision of a host computer, and different types of foods are packaged according to instructions in different ways. If there is a product change request, just change the calling program in the host.
The field of security testing gradually expands security. It is the first key word in any industry, and even more so in the packaging industry. In the food industry, safety inspection technology has developed rapidly in recent years. Specifically speaking, it is to improve the accuracy of the ingredients of mechanical products. At the same time, it is also necessary to be able to record information such as storage operators, ingredient types, production time, and equipment numbers. We can achieve our purpose through weighing, temperature and humidity sensors and other functional components.
Motion Control Technology Motion control technology has developed rapidly in China, but the momentum of development in the packaging machinery industry has shown a lack of momentum. The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements. It is mainly used in processes such as loading and unloading, conveyors, marking machines, palletizing machines and depallets. Professor Li believes that motion control technology is one of the key factors in distinguishing high, medium and low-end packaging machinery, and it is also a technical support for upgrading packaging machinery in China. Because the whole machinery in the packaging industry is continuous, it has extremely high requirements for speed, torque, precision, and dynamic performance. This is exactly the same as the characteristics of servo products.
The implementation of manufacturing execution system needs to break through the bottleneck In recent years, the integration technology has developed rapidly in the packaging industry. There are many types of packaging machinery and equipment, which makes it difficult for the interface between the manufacturers' product interfaces, equipment and industrial computers, and information and equipment. In this case, packaging companies turn to the Manufacturing Execution System (MES) for solutions. However, it is understood that the application of MES in the packaging industry is not as good as people expected.
China's packaging industry has weak self-development capabilities and lacks a base for scientific research and production. At the same time, there are few domestic leading enterprises with large production scale. In fact, compared with packaging machinery products from Germany, Italy and other countries, the gap is the rise of domestic machinery manufacturers. This is especially true for machines that use metal strips, such as fully automatic steel strapping machines.
