Design trend of packaging machinery in German market

Germany, the United States, Japan and Italy are all major countries of packaging machinery in the world. German packaging machinery is in a leading position in terms of design, manufacturing and technical performance. In 2002, the output value of German packaging machinery reached 3.4 billion euros, and 70% of European packaging machinery was produced in Germany. Germany exports 77% of its packaging machinery, accounting for 29% of the world's packaging machinery export market, ranking first. China is an important exporter of German packaging machinery, especially food processing and packaging machinery

the design of German packaging machinery is based on Market Research and market analysis, and the goal is to strive to serve customers, especially large enterprises. With the development of science and technology and the intensification of market competition, the demand of customers is also increasing. This demand is reflected in the following aspects: first, improve production efficiency to meet the needs of delivery time and reduce process circulation costs. For some products, it is also required that packaging machinery and production machinery should be connected; Second, in order to meet the needs of product renewal and change, packaging machinery should have high flexibility and flexibility; Third, when the equipment fails, remote diagnosis service is required; Fourth, environmental pollution, including less noise, dust and waste; Fifth, the investment in purchasing equipment should be as little as possible, and the price should be as low as possible

in order to meet customer requirements, German packaging machinery manufacturers and design departments have taken many measures

the degree of automation of process flow is getting higher and higher

a few years ago, automation technology accounted for only 30% of the design of packaging machinery, and now it accounts for more than 50%. Moreover, the speed control is inaccurate, and Microcomputer Design and electromechanical integration control are widely used. The degree of automation of packaging machinery continues to improve, first, to improve productivity, second, to improve the flexibility and flexibility of equipment, and third, because the actions that packaging machinery needs to complete are complex, they are mostly completed by robots. For example, chocolate candy uses a manipulator to replace the original manual action, so that the packaging maintains the original style

the automatic design of packaging machinery has the following two characteristics:

first, 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. During operation, under the information and monitoring of the computer-controlled camera, the manipulator completes the specified actions according to the computer instructions 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 computer-controlled cameras and detectors are often used in packaging machinery to distinguish. The camera has been developed to be able to check and distinguish 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 rotating speed should be changed according to the change of materials, and it should be controlled to work under the optimal state, so as to realize automatic cleaning, automatic disinfection and automatic cleaning

improve production efficiency, reduce process costs, and meet production requirements to the greatest extent.

German packaging machinery is good at beverage, beer filling machinery and food packaging machinery, and 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 per hour, and cigarette packaging is 12000 pieces per minute

increasing the speed of the machine is a complex problem. The higher the speed, the lower the production cost of a single piece. However, the use area of the plant will increase, and the failure rate will also increase, which will reduce the efficiency. Therefore, we should look for the junction of the two curves

in addition, the motor speed is also limited. Generally speaking, increasing the speed by 15%-20% will bring a series of complex problems

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

if continuous work or multi head work mode is adopted. The working modes of packaging machinery are intermittent and continuous, which can work continuously, which improves the production efficiency; 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

it can also reduce the scrap rate and provide a fault analysis system. The production loss caused by waste products is amazing, including product loss and material loss, so we should try to reduce the loss of waste products; When selling packaging machinery, it should also provide a fault analysis system for modal analysis to find faults, or remote diagnosis through Internet. In the future, production efficiency should be improved

it can also gasify the product machinery and packaging machinery. Many products require packaging after production to improve production efficiency. For example, qiaojinli 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 production capacity

to adapt to product changes, the design should have good flexibility and flexibility

due to the fierce competition in the market, the cycle of product upgrading has become shorter and shorter. For example, the production of cosmetics changes every three years, or even every quarter, and the production volume is large. Therefore, the packaging machinery is required to have good flexibility and flexibility, so that the life of the packaging machinery is far away. Lei Wen, director of the environmental protection department of the Department of energy conservation and comprehensive utilization of the Ministry of industry and information technology, also said that it is larger than the life cycle of the product, so as to meet the economic requirements

the flexibility and flexibility of packaging machinery and equipment are often shown in the following three aspects:

first, the flexibility of high quantity stability. It can pack not only single products, but also different batches of products

the second is the flexibility of structure. The whole equipment is composed of units, which can adapt to the changes of products by changing one or several units

the third is the flexibility of supply. Unit combination can be adopted, and each unit can be supplied together. For example, the candy packaging machine combines different units on a common basis, including three feeding ports and four different folding packaging forms. In this way, a machine can package different kinds of candy at the same time, which is operated by multiple manipulators. Under the monitoring of a camera, it commands its action, and which candy can be packaged. 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

the design of packaging machinery in Germany attaches particular importance to providing manufacturers with a complete system scheme that comprehensively considers the structure and economy according to the needs of users, demonstrating the operation to users with computer simulation technology, and modifying it after soliciting opinions. When providing users with automatic production lines or production line equipment, we pay special attention to the integrity of complete sets. Whether it is high-tech added value or relatively simple equipment, it is provided according to the requirements of matching

German packaging machinery manufacturers will also provide complete sets of equipment as their goal. For example, there are 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 production capacity of 1200 bottles per hour, two more lines are needed. Therefore, the production of the whole beverage filling line needs to occupy half the area of the football field. They require that all these equipment can be provided by one manufacturer. At present, a major weakness of packaging machinery production in China is that there are many single machines, few complete assembly lines, many main machines, few auxiliary machines, and poor compatibility. This practice of Germany is worth learning from

computer simulation design technology is widely used

with the accelerating development of new products, computer simulation technology is widely used in the design of packaging machinery in Germany, that is, various machine elements are stored in the computer as a database, 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 production capacity that can be achieved, the number of waste products, whether each link of the production line can match the production, where the bottleneck is, etc. the curve displayed on the display screen is clear at a glance, and the model can be modified according to the opinions of customers. The computer synthesis speed is very fast, so the modification work is fast and convenient until the customer or designer is satisfied. The 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. The so-called economy is not entirely the cost of mechanical equipment itself, but more importantly, the operating cost, because equipment Depreciation accounts for only 6%-8% of the cost, and the rest is the operating cost
