[China Packaging News] the increasing market requirements have prompted the packaging machinery industry to constantly seek new ways of development. In recent years, in order to reduce production costs, packaging enterprises have considered building flexible production lines to complete the flexible manufacturing of enterprises, which is supported by efficient servo control systems. It can be seen that control and integrated product technology are playing an increasingly important role in the development of packaging production lines

in order to achieve the production goal of higher speed and more flexibility, the functions traditionally realized by mechanical components are now more completed by servo systems. For example, electronic cams and gears replace mechanical cams and gears, and there is no need for high-precision synchronization between multiple shafts with hard/mechanical connections. Therefore, the packaging production line not only needs interlocking control, but also needs fast and high-precision servo control. The integrated controller/system that can meet the above functions at the same time will bring more and more benefits to users in terms of programming, debugging and maintenance than the control scheme of independent PLC independent servo controller

in order to complete flexible production, the equipment in each process section of the packaging production line is required to be closely coupled with each other, and the packaging production line is required to be interconnected with other production lines. Because different controllers control different process sections or production lines, this brings the problem of coordination between different controllers. Therefore, the International Packaging Association user organization (omac/pacml) has stated the structured and standardized machine state management function of object encapsulation. Accordingly, the control system integrating this function can ensure that users can complete the coordination of the whole line and even the whole factory production in less time and cost

the completion of flexible production also means that the real-time data of the control system should be integrated with the two-way communication ability of the relational database of the factory production information management system. In other words, the production control instructions used in the single pool generation and production scheduling management software in the automotive field should be timely transmitted to the packaging production line control system; Moreover, the control system of packaging production line should send the running state and production state back to the production information management system in time

in order to achieve greater continuous production and less system recovery time, more users also realize the value and benefits of the packaging production line control system after 108 years of centralized maintenance and management, which can support hot plug of modules and rapid acquisition of diagnostic information

in terms of total T-scan time, flexible production has not only changed our production mode, made product packaging more flexible, but also opened up our development ideas, led to multiple rounds of changes in the packaging machinery market, accelerated the commercialization of innovative thinking, better played the potential of packaging machinery, reached a new level, and laid a solid foundation for China to become a big country of creation

this makes the packaging machinery industry start to investigate the connotation of flexibility as a whole, that is, the flexibility of quantity, structure and supply. To make the packaging machinery have good flexibility and flexibility, and improve the degree of automation
