Looking at the packaging market in China, the packaging machinery industry has a very big development space, the enterprises continue to search for the gap, learn new technology, update technology into the traditional mechanical manufacturing technology, so that soft power and hard strength in depth, and ensure social development.
From the market competition of each enterprise, the renewal cycle of the product is getting shorter and shorter, which makes a high requirement for the flexibility and flexibility of the packaging machinery, that is, the life of the packaging machinery is far greater than the life cycle of the product. This is the only way to meet the requirements of production economy. This enables us to start a comprehensive survey of the connotation of flexibility concept, that is, quantity flexibility, structural flexibility and supply flexibility. The flexibility of supply also involves the motion control system of packaging machinery.
In the process of the industrialization of packaging industry, the manufacturing technology has completed the scale and diversification, and the demand for diversification and even individuation further aggravates the market competition. In order to reduce the production cost, the packaging enterprises have considered the construction of flexible production line in succession, and complete the flexible manufacturing of the enterprise to provide the efficient servo control system. Support。 In the development of packaging production line, control plays an increasingly important role in integrating product / technology.
The completion of flexible production means the ability to control the real-time data of the system to communicate in a two-way communication with the relational database of the factory production information management system. That is to say, the production control instructions from the order pool generation and production scheduling management software can be delivered to the packaging production line control system in time. Moreover, the packaging production line control system will be able to send the operation state and production state back to the production information management system in time.
In order to complete the flexible production, the equipment in the packaging production line is tightly coupled to each other, and the packaging production line is required to interact with other production lines. Because different controllers control different process sections or production lines separately, this brings different controllers' coordination problems. Therefore, the International Packaging Association user organization (OMAC/PACML) states the structured and standardized machine state management function of the object encapsulation. Accordingly, the control system integrated with this function can guarantee the user to complete the coordination of the whole line and even the whole factory in less time and cost.
Specifically, to make the packaging machinery have good automation and flexibility, and improve the degree of automation, we need to adopt microcomputer technology, function module technology, and monitor the work of multiple manipulator, so that the requirements of product change only need to be transferred.
With the continuous development and progress of science and technology, the future microelectronics, computers, industrial robots, image sensing technology and new materials will be more and more widely used in packaging machinery. Enterprises need to learn and introduce new technologies to produce high production efficiency, high automation, reliability, flexibility and technology. The high volume of packaging equipment marched. Build a new packaging machinery, leading packaging machinery to integrate, efficient, intelligent and other direction.
In recent years, domestic food packaging technology experts have made gratifying achievements in introducing cooperation and independent originality. Multi-function is an important trend in the development of new equipment, because the variety and update of the food variety, the manufacturer's requirements for the equipment are versatile and adaptable.
In addition, new technologies such as servo motors and electro-optical tracking are widely used in the newly launched devices, so that their automatic control capability is greatly improved. Such as the automatic line of chocolate compound products, the whole line is made up of nearly 20 units. Due to the difference of different kinds of technological requirements, not only the problem of the adjustment of each unit itself, but also the problem of speed coordination between the units in the process of operation, the unit uses a total frequency converter to control the speed control frequency converter of each unit.
In general, flexible production has not only changed our production mode, making the packaging more flexible, more development of our thinking, making the packaging machinery market multiple changes, speeding up the innovative thinking into a better commercialization, making the potential of packaging machinery better play out, reaching a new level. This makes the packaging machinery industry begin to inspect the connotation of flexibility concept, that is, the flexibility of quantity, the flexibility of structure and the flexibility of supply. Packaging machinery must have good flexibility and flexibility, and enhance automation.
