Although the domestic packaging machinery market has broad prospects, many problems such as weak automation, unattractive appearance, short life, poor stability and reliability also make domestic packaging machinery products lack competitiveness. my country's packaging industry has weak self-development capabilities and lacks scientific research and production bases. At the same time, there are few leading domestic companies with large production scales. Compared with the packaging machinery products of Germany, Italy and other countries, the gap is the room for improvement of domestic packaging machinery manufacturers, especially in the packaging machinery with metal belts such as automatic steel belt balers.
With the intervention of control and driving technology and the concept of digital-to-analog transformation, the packaging machinery market has undergone many revolutions. At present, my country has become the world's largest producer and exporter of commodities. At the same time, the eyes of the world are also focused on the fastest growing, largest and most potential Chinese packaging market. Flexible production—making product packaging more sensitive Now, in order to adapt to the fierce competition in the market, major companies have shorter and shorter product replacement cycles.
For example, the production of cosmetics can generally be changed every three years, or even every quarter, and the demand is relatively large at the same time (such as wooden boxes used for packaging and installation of goods), so the flexibility and sensitivity of packaging machinery are highly proposed. Requirements: that is, the life of the packaging machinery is much greater than the life cycle of the product. The concept of flexibility can be considered mainly from these three aspects: the sensitivity of quantity, the sensitivity of structure and the sensitivity of supply. Specifically, in order to make the packaging machinery have good flexibility and sensitivity, and improve the degree of automation, it is necessary to use microcomputer technology, functional module technology, etc.
For example, on a food packaging machine, different units can be combined on the basis of one machine, and different types of products can be packaged together by using multiple feeding ports and multiple different folding packaging methods. Multiple manipulators operate under the supervision of a host, and pack different types of food in different ways according to instructions. If there is a requirement for product changes, it is only necessary to change the calling program in the host.
The field of safety inspection gradually expands Safety is the first keyword in any profession, especially in the packaging machinery profession. In the food industry, safety testing technology has developed rapidly in recent years. Specifically, 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 and store information such as the operator, ingredient type, production time, and equipment number. We can achieve our goals through functional components such as weighing and temperature and humidity sensors. Motion control technology The development of motion control technology in China is very rapid, but the development momentum in the packaging machinery industry seems to be lacking.
The function of motion control products and technologies on packaging machinery is mainly to meet the requirements of precise position control and strict speed synchronization, and is mainly used for loading and unloading, conveying, marking, packaging and other processes. Professor Li believes that motion control technology is one of the key factors to distinguish high-end, medium-end and low-end packaging machinery, and it is also the technical support for the upgrading of packaging machinery in my country. Because the whole machine in the packaging industry is continuous, it has extremely high requirements for indicators such as speed, precision and dynamic functions, which also fits the characteristics of servo products.
The application of the manufacturing execution system needs to break through the bottleneck. In recent years, integration technology has developed rapidly in the packaging machinery industry. There are many varieties of packaging machinery and equipment, which makes the product interface docking of different manufacturers, the transmission mode between equipment and industrial computer, information and equipment encounter great difficulties. In this case, packaging companies turn to manufacturing execution systems (MES) for solutions.
But it is understood that the application of MES in the packaging industry is not as good as people expected.
