Interpretation of the four key words of packaging machinery automation
[Guide: safety detection technology, motion control technology, flexible production and manufacturing execution system (MES) have become several key words of concern to domestic packaging machinery manufacturers. Then behind the keywords, where is the way out for domestic packaging machinery enterprises? Where are the opportunities for supporting automation products? Let's interpret these four key words one by one.]
20 years ago, PLC, which was first applied to packaging machinery products, opened the era of packaging machinery automation technology. After that, with the intervention of control and drive technology, servo technology and digital concept, the packaging machinery market has experienced several rounds of changes. At present, China has become the world's largest commodity production and export country. At the same time, global attention is also focused on the fastest-growing, largest and most potential Chinese packaging market
although the domestic packaging machinery market has a broad prospect, problems such as single machine automation, poor stability and reliability, unsightly appearance, short service life and so on have also made domestic packaging machinery products widely criticized. Professor lizhenliang, School of mechanical engineering, Tianjin University of science and technology, is deeply impressed by this: China's packaging industry has weak self-development ability, and there is a lack of pilot bases for scientific research and production. At the same time, there are few leading enterprises with large production scale in China. In fact, compared with the packaging machinery products of Germany, Italy and other countries, the gap is the room for domestic machinery manufacturers to rise
in helping domestic packaging machinery enterprises complete scientific research projects, Professor Li also summarized some technical routes suitable for the development of domestic packaging machinery enterprises. He stressed that safety detection technology, motion control technology, flexible production and manufacturing execution system (MES) have become several key words of concern to domestic packaging machinery manufacturers. So behind the keywords, where is the way out for domestic packaging machinery enterprises? What are the opportunities for supporting automation products? Let's interpret these four keywords one by one
safety detection technology the detection field is gradually expanding
safety is the first keyword in any industry, especially in the packaging industry. In the food industry, safety detection technology has developed rapidly in recent years. Professor Li first introduced the specific development of safety detection technology to us by taking the detection project that he previously helped a company in Tianjin as an example. He said: specifically, our project is to help the company's mechanical products complete the accuracy of batching. Whoever operates the equipment must achieve the high accuracy of batching. At the same time, it is also necessary to be able to trace the operator, batching variety, production time, equipment number and other information. However, he stressed that this project mainly applies weighing, temperature and humidity sensors and other products, and has not yet involved the scope of chemical detection. Moreover, the inspection of the packaging industry is more complex
at present, the embodiment of food safety in packaging machinery is not limited to simple physical parameters, but also pay attention to food color, raw materials and other factors. For example, Professor Li said: the application scope of packaging machinery is expanding, which constantly puts forward new requirements for machinery manufacturers and automation product suppliers. For example, in food packaging, we should be able to monitor the bacterial content of the product itself and packaging materials. Therefore, in the field of automation products, machine vision and other technologies have great potential for development
motion control technology is the key to the upgrading of domestic packaging machinery
motion control technology is developing very rapidly in China, but the development momentum in the packaging machinery industry is weak. The function of motion control products and technology in packaging machinery is to achieve accurate position control and strict speed synchronization requirements, which are mainly used in loading and unloading, transportation, marking, stacking, destacking and other processes. Professor Li believes that motion control technology is one of the key factors to distinguish high, medium and low-end packaging machinery, and it is also the technical support for the upgrading of packaging machinery in China
because the whole mechanical assembly line in the packaging industry is continuous, there are high requirements for speed, torque, accuracy and dynamic performance, which also fits the characteristics of servo products. Professor Li introduced that the bus type motion controller introduced by major automation companies has a broad application prospect in the packaging machinery industry. Through the high-speed bus communication mode, the high-end functions such as accurate and high-speed tracking, the conversion of multiple position control modes and the exchange of information and data at multiple communication ports are realized. As the domestic packaging machinery companies are facing the situation of labor-intensive transformation, the management of the company also realizes that while the level of motion control technology is improved, the production cost is also reduced correspondingly
flexible production makes product packaging more flexible
at present, in order to adapt to the fierce competition in the market, the cycle of product renewal and replacement of sample type can be the generation of full section material is getting shorter and shorter. It is understood that the production of cosmetics can generally change every three years, or even every quarter, and the production volume is relatively large, so there are high requirements for the flexibility and flexibility of packaging machinery: that is, the life of packaging machinery is far greater than the life cycle of products. Because only in this way can we meet the requirements of product production economy
Professor Li believes that the concept of flexibility should be considered from three aspects: quantity flexibility, structure flexibility and supply flexibility. Specifically, to make the packaging machinery have good flexibility and flexibility, and improve the degree of automation, we need to use microcomputer technology, module technology and so on. For example, in a food packaging machine, different units are combined on the basis of one machine, and different types of products can be packaged at the same time by using multiple feeding ports and different folding packaging forms. Multiple manipulators operate under the monitoring of a camera and pack different kinds of food in different ways according to instructions. If there is a requirement for product change, just change the program in the camera, so that the equipment can carry out good flexible productionmanufacturing execution system packaging machinery application needs to break through the bottleneck
in recent years, integrated technology has developed rapidly in the packaging industry. There are many kinds 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 enterprises turn to manufacturing execution system (MES) for solutions. However, according to the annual output range of high-end regenerative medicine products of 5billion yuan, the application of MES in the packaging industry is not as good as expected
before, many packaging enterprises introduced ERP. They hope that with this platform, the management can easily access and analyze the operation data, understand the actual and immediate situation of production, and monitor the operation of the workshop. However, because it can not solve the complex management problems of enterprises, although it was raised more in previous years, it has not developed. Accordingly, the development of MES, which is integrated with ERP, is not satisfactory. Professor Li explained when talking about the development of ES in cooperation with Yucheng pesticide factory in the biological agent project of M green insecticidal sterilization and nitrogen fixation
Professor Li introduced that when customers apply MES, especially in the implementation process, they will always encounter various problems in building a high-level talent team. For example, a packaging enterprise has raised many problems in how to optimize the whole workshop manufacturing process, and there are also questions about whether the optimized process is reasonable. At the same time, users attach great importance to specific information, such as tracing the production process of the product according to the bar code, the links that make mistakes, and how to make mistakes. Therefore, there are still many details about the development of MES in the packaging industry
