The trend of packaging machinery market (Part 1)

the degree of automation continues to improve

improving the degree of automation is the most important trend in the development of packaging machinery. The United States, which ranks first in both variety and output in the world, attaches great importance to the close combination of packaging machinery and computers, realizes electromechanical integrated control, and applies more automatic operation procedures, data collection systems, and automatic detection systems to packaging machinery. Japan is good at microelectronics technology, which is used to control packaging machinery, effectively promoting the improvement of unmanned operation and automation. Germany, which is a world leader in measurement, manufacturing and technical performance, also attaches great importance to improving the degree of automation. A few years ago, in the design of German packaging machinery system, automation technology accounted for only 30% of the whole system operation and operation, and now it accounts for more than 50%. Its automation design has the following two main characteristics:

A. each manipulator is controlled by a separate computer. In order to complete complex packaging actions, a packaging machine needs to be completed by multiple manipulators. When completing the packaging action, under the information recorded and monitored by the computer-controlled camera, the manipulator completes the specified action according to the instructions issued by it to ensure the packaging quality

b. high resolution of material and thickness. In the process of packaging, the thickness and material changes of packaging materials are not easy to be recognized by the human eye, so the computer-controlled camera and detector are used in the packaging machinery to distinguish the thickness and material changes of packaging materials, which are displayed on the display screen. At the same time, the machine changes the performance test numbers and revolutions of the breaking strength, breaking elongation and maximum experimental power of the space cotton tensile machine according to the changes of the identified materials, The control works in the optimal state

high productivity and high reliability

Gome, Japan, Germany and Italy, the world's four largest packaging machinery powers, attach great importance to the needs of the market and users, and take improving machine revolutions and productivity as important indicators for design pursuit. At present, the filling speed of beverages in Germany can be as high as 1200 bottles/h, cigarette packaging 12000 pieces/min, and the world's fastest tea packaging machine, which integrates bag making, weighing, filling, vacuum pumping, sealing and other processes, can reach 350 bags/min

an important way to improve productivity is to increase the speed, but increasing the speed of the machine is a complex problem; The higher the speed, the lower the production cost of a single piece, the higher the usable area of the plant and the higher the failure rate, which will reduce the efficiency. Therefore, the optimal combination of the two should be sought; Increasing the speed of the machine will also have a related impact on the material, reliability, performance and life of other components. Generally speaking, improving the late protection will also cause a large cost. 15% - 20% of the speed will bring a series of complex problems, not to mention the limited speed of the motor, so you can't think as fast as you want

in addition to increasing the speed, improving productivity can also be solved through other channels

a. adopt continuous work or multi station and multi head work mode. There are two working modes of packaging machinery: intermittent and continuous. In the design, we should think about which high and low temperature impact testing machine can work continuously to improve productivity; Multiple stations or production lines can also be designed in one equipment to produce the same product or series products of different specifications, but the reliability must be improved. The Italian low-dose particle packaging machine adopts mechanical drum metering, continuous sealing and cutting, one machine with multiple stations, and the packaging speed can reach 120 Bags/min

b. reduce the scrap rate and provide a fault analysis system. Waste products cause the greatest loss to production, not only the loss of products, but also the loss of materials. Therefore, we should try our best to reduce the loss of waste products; The packaging machinery should also be equipped with a fault analysis system for maintenance service, that is, modal analysis to find faults, or remote diagnosis through inter, so as to meet the needs of customers to the greatest extent. In the future, the packaging machinery will be further intelligent, that is, the equipment will find and solve the fault by itself. Reducing the scrap rate and failure rate effectively ensures high productivity

c. integrate product machinery and packaging machinery. Many products can start from one production line and then be packaged, which is also conducive to improving product productivity. For example, the chocolate production equipment and packaging equipment produced in Germany are controlled by one system. The key to the integration of the two is to solve the problem of matching each other in productivity. It is often the packaging machinery that becomes the bottleneck of production. Therefore, it is necessary to provide two types of equipment that can match the productivity

the powerful country of packaging machinery also attaches great importance to improving the reliability and stability of packaging machinery. First, formulate product reliability standards and processing specifications, and strictly implement them in production; And pay close attention to the processing quality of machine, electricity, gas, liquid and other supporting basic parts. The reliability of packaging machinery is an important indicator of product quality and product life. The reliability and quality of basic components are an important guarantee for the reliability and quality of the whole machine. (to be continued)
