Five characteristics of the development trend of German packaging machinery design

with the development of science and technology and the intensification of market competition, customers have higher and higher requirements for mechanical performance, mainly in the following aspects: high productivity to meet the requirements of delivery time and reduce the needs of technological circulation costs; For some products, packaging machinery and production machinery are also required to be connected; To meet the needs of product renewal, packaging machinery should have high flexibility and flexibility; There are few equipment failures, and remote diagnosis service can be carried out in case of failure; Less environmental pollution, including noise, dust and waste pollution; The investment in purchasing equipment should be as little as possible, and the price should be as low as possible. In recent years, German packaging machinery manufacturers and design departments have taken the following measures to meet these requirements of customers:

improve process automation

adopt computer-controlled design. A few years ago, automation technology accounted for only 30% of packaging machinery design, and now it accounts for more than 50%. A large number of Microcomputer Design and electromechanical integrated control are used. The automatic design of packaging machinery has the following two main features:

first, each manipulator is controlled by a separate computer. In order to complete complex packaging actions, a packaging machinery needs to be completed by multiple manipulators. When completing the packaging action, under the information and monitoring of the computer-controlled camera, the manipulator completes the specified action according to the instructions of the computer program to ensure the quality of the packaging

second, it has high resolution of material and thickness. In the packaging process, the thickness and material changes of packaging materials are not easy to be recognized by human eyes, so in the design of packaging machinery, computer-controlled cameras and detectors are often used to distinguish the thickness and material changes of packaging materials ldquo; We are following the guidance of nature rdquo; Joshua Martin, a doctoral student, explained that it was humanization. The camera has been developed to check and identify the captured pictures by itself and display them on the display screen. At present, the rotating speed of the machine cannot be changed during processing; In the future, the rotation speed should be changed after identification according to the change of materials, so as to control the work in the optimal state, complete the packaging process in the shortest time, and realize automatic cleaning, automatic disinfection and automatic cleaning

seek ways to improve productivity and reduce process costs

German packaging machinery, especially beverage, beer filling machinery and food packaging machinery, has the characteristics of high speed, complete set, high degree of automation and good reliability. Its beverage filling speed is as high as 1200 bottles/hour, and cigarette packaging is 12000 pieces/minute. Increasing the speed of the machine is a complex problem. The faster the speed is, the lower the production cost of a single piece is, but the use area of the plant will increase. In addition, the speed of the motor is also limited, so you can't go as fast as you want. Generally speaking, increasing the speed by 15% - 20% will bring a series of complex problems

to improve productivity, in addition to increasing the speed, we can also try to solve it from other channels:

first, we should adopt continuous work or multi head work mode. There are intermittent and continuous working modes of packaging machinery. When designing, we should strive to design it to work continuously, which will improve productivity; There can also be multiple production lines in one equipment to produce the same product or several different products, but the reliability must be improved

second, reduce the scrap rate and provide a fault analysis system. Waste products cause huge losses to production, not only product losses, but also material losses. Therefore, the scrap rate should be reduced as much as possible; When selling packaging machinery, it should also provide fault analysis system for maintenance services, 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 should be further intelligent, that is, the equipment should find and solve the faults by itself, so as to reduce the scrap rate and failure rate, and improve the normal productivity. 4. Hardness test

third, integrate product production machinery and packaging machinery. Many products are packaged after production, which is also conducive to improving product productivity. For example, the chocolate production equipment and packaging equipment produced in Germany are controlled by a system. The key to the integration of the two is to solve the problem of matching each other in productivity, in which packaging machinery often becomes the "bottleneck" of production, so it is necessary to provide equipment with different productivity

adapt to the changes in the packaging market and pay attention to the flexibility of equipment

in order to adapt to the fierce competition in the market, many packaging products have shorter and shorter replacement cycles. For example, the production of cosmetics changes every three years, or even every quarter, and the production volume is large. Therefore, it is required that the packaging machinery has good flexibility and flexibility, so that the life of the packaging machinery is much longer than the life cycle of the product, so as to meet the requirements of economy

in order to make the packaging machinery have good flexibility and flexibility and improve the degree of automation, microcomputer technology, module technology and unit combination must be widely used. In order to adapt to the changes of packaging product varieties and packaging types, the flexibility and flexibility of packaging machinery and equipment are often shown in the following three aspects:

flexibility of quantity. It can not only package a single product, but also adapt to the packaging of different batches of products

flexibility of construction. The whole equipment is composed of units, and one or several units can adapt to the changes of products

flexibility of supply. Unit combination is adopted, and all units are combined together for supply. For example, candy packaging machine combines different units, three feeding ports and four different folding packaging forms on a common basis, so that a machine can package 8 ~ 10 different kinds of candy at the same time. It is operated by multiple robots, and under the monitoring of a camera, it commands its action, and packages different kinds of candy in different ways according to instructions. If the product changes, just change the program in the camera, so that the equipment has good flexibility and flexibility

provide complete sets of equipment on the premise of user needs

German packaging machinery design, on the premise of user needs, provide structural and economic complete system solutions for production enterprises, demonstrate the operation to users with computer simulation technology, and modify it after consulting users' opinions. When providing users with automatic production lines or production line equipment, we pay special attention to the integrity of complete sets of equipment. Whether it is high-tech, high value-added equipment, or relatively simple equipment, they are provided according to the matching requirements

German packaging machinery manufacturers will also provide complete sets of equipment as their goal. For example, a beverage filling line has more than 200 microcomputer components, many pipelines and display screens, and more than 100 software programs that control various packaging actions. In order to meet the productivity of 1200 bottles/hour, two lines must work together. Therefore, the production of the whole beverage filling line needs to occupy half the area of the football field, and all equipment is required to be in one manufacturer. Thinking of China, a major weakness of current packaging machinery production is that there are more single machines and less complete assembly lines; There are many main machines, few auxiliary machines and poor compatibility. This practice of Germany is worth learning from

use computer simulation technology to shorten the cycle of machine development and design

with the accelerating speed of new product development, you can know whether there is a problem with the amplifier unit. Computer simulation technology is widely used in packaging machinery design in China, that is, various machine elements are stored in the computer in the form of database, and the drawings are digitized and input into the computer, and the computer can automatically synthesize them into three-dimensional models. Then input the actual production data and indicators, and input all kinds of possible faults. The computer three-dimensional model can operate in imitation of the real working situation, and demonstrate the productivity that can be achieved, the number of waste products, whether each link of the production line can match the production, and where the "bottleneck" is, so that customers can see at a glance according to the curve displayed on the display screen, and modify the model according to customers' opinions. The computer synthesis speed is very fast, so the modification work is fast and convenient until the customer or designer is satisfied. Computer simulation design technology has greatly shortened the development and design cycle of packaging machinery

the design of packaging machinery should not only pay attention to its function and efficiency, but also pay attention to its economy. However, the measurement object of economic extension is not entirely the cost of mechanical equipment itself, but more importantly, the operating cost, because the depreciation of equipment accounts for only 6% - 8% of the cost, and the other is the operating cost
