New development trend of American packaging machinery
The US packaging industry started in the early 20th century and has developed rapidly since World War II. It has gradually established and formed a complete and independent industrial system that includes packaging materials, packaging technology and packaging machinery. The total output value of its packaging industry accounts for 3% of the total output value of the national economy. According to the US industry survey analysis, the largest use of its packaging machinery industry is the food industry, followed by household cleaning supplies and cosmetics industry, medical supplies and tobacco industry.
The speed of innovation is always at the top
The food industry is the largest use of packaging machinery in the United States. Almost all models and models are used in the food industry. Among them, the annual demand for packaging machinery for soft drinks is the largest, accounting for 50% in 2005; the demand for packaging machinery in the food industry from 1994 to 2005 has an average annual growth rate of 7%. It is precisely because of the tens of thousands of annual launches by the US food industry This kind of new product accelerates the upgrading of packaging machinery, so the packaging machinery innovation speed required by the US food industry has always been in the first place.
Value brand
Brand is the soul of the company. From the perspective of packaging machinery market share, the top ten packaging machinery companies in the United States are: Barry-wehmillre, Beinis, SA-SIBSPA, AveryDeeeison, Bosch, CrownCork&ha, DougalsMachine , RAJoues Cohpany, Kliklk and Krones. Their success in operation mainly depends on three aspects: one is to strive to increase the visibility of the company's packaging machinery brand; the second is to pay attention to the sales performance of the company; the third is to attach great importance to the after-sales service of the company's products.
Automation, high efficiency and energy saving of packaging machinery
The current promising packaging machinery in the United States is: horizontal pillow-type microcomputer-controlled packaging machinery equipped with servo motors and power control devices with good film tension. In the future, microelectronics, computers, industrial robots, intelligent, image sensing technology and new materials It will be more and more widely used in packaging machinery, and packaging machinery is increasingly developing in the direction of automation, high efficiency and energy saving.
Automated operating procedures have been applied to more advanced packaging systems, such as the application of PLG equipment and data collection systems representing the trend of advanced packaging systems. In order to ensure a high level of productivity, automatic inspection systems and efficient automated systems are essential.
The packaging industry uses lighter materials to reduce shipping costs, uses specially designed components and systems to shorten production time, and works with suppliers and manufacturers to provide multiple packaging operations with the least amount of materials.
Application of new technology
Packaging automation procedures have been widely used. In order to cater to consumers, the US packaging industry tends to use information labeling systems extensively. Because the government requires packaging products to be marked with nutritional ingredients, instructions for use, and bar codes, the labeling system is being developed towards multi-functional information.
American scientists have developed a brand new integrated circuit detector, which can detect the deterioration time of a certain food or a certain beverage. This new food quality detection device is composed of a sensor and a scanner. Its energy comes from the radio waves emitted by the scanner. The main material of the sensor is lead. When packing food, put it in the food box together. When carrying out the inspection, the inspector only needs to point the scanner at the food to emit radio waves. The radio wave signal sent by the scanner will cause the food to vibrate, and at the same time emit the score wave. The score wave is reflected on the wall of the food box first, and then Conduction to the sensor, by using a standard database to calibrate the degree of vibration, the time of vibration transmission and the transmission speed of the music score, the time when the detected food deteriorates can be determined instantly, and the detection result is quite accurate.
Packaging tends to be diversified and multi-purpose
The packaging industry is changing rapidly to cater to changes in consumer demand, and production tends to diversify. Taking the food industry as an example, since the consumption demand of Americans for food has changed to multiple specifications, diversification and specialization, the food processing industry has invested in the development of packaging lines with more flexible and mobile functions. It took 2-3 years to develop a new packaging product in the past few years. Now it takes only half a year to get the new product to market. This fully shows that when the US packaging industry develops new varieties and new products, the speed and time are short.
Because the packaging industry is pursuing combined, simplified and mobile packaging equipment, packaging machinery manufacturers are increasingly focusing on the development of high-efficiency, multi-purpose, smaller, more flexible packaging equipment.
Provide more convenient and safe packaging
According to the forecast of the US Census Bureau, the United States will enter an aging society by 2025. The US packaging industry has fully considered the potential needs of elderly consumers for packaging products and began to develop packaging that adapts to the characteristics of the future aging society, such as with a zipper The packaging industry is committed to providing consumers with more convenient packaging.
Packaging design is trending towards international standards
American companies are committed to seeking favorable packaging that is unique to the global market in terms of packaging materials, equipment, and sales. In order to compete in the global market, manufacturers are working to develop a policy that allows them to conform to the international standards emphasized by designers.
As Mr. Charles Uska, President of the American Packaging Machinery Manufacturing Association said:'We are entering a new world of packaging with mechatronics, laser scanning, radio frequency emission, nanotechnology and simplified systems. '
German packaging machinery development trend
German packaging machinery design based on market research and market analysis, and strive to serve customers, especially large enterprises. With the development of science and technology and the intensification of market competition, customers have higher and higher requirements on mechanical performance, mainly in the following aspects: 1. Improve productivity to meet delivery time requirements and reduce process cost Needs; for some products, packaging machinery and production machinery are also required to be connected. 2. To meet the needs of product updates, packaging machinery must have higher flexibility and flexibility. 3. There are few equipment failures, and remote diagnosis service can be provided if something goes wrong. 4. Less environmental pollution, including less noise, dust and waste pollution. 5. The investment in equipment purchase should be as low as possible, and the price should be as low as possible.
German packaging machinery manufacturers and design departments have adopted the following measures to meet customer requirements:
Improve the degree of automation
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 designs and mechatronics control are used to improve the automation of packaging machinery. Its purpose is: first, to increase productivity; second, In order to improve the flexibility and flexibility of the equipment; the third is to improve the packaging machinery's ability to complete complex actions, that is, the use of robots to complete the packaging process.
Packaging machinery automation design has the following two main characteristics:
①Each manipulator is controlled by a separate computer
In order to complete complex packaging actions, a packaging machine needs to be completed by multiple manipulators. Under the information captured and monitored by the computer-controlled camera, the manipulator performs the prescribed actions according to the instructions of the computer program to ensure the quality of the packaging.
②With high resolution ability to material and thickness
During the packaging process, the thickness and material changes of the packaging materials are not easy to be discerned by the human eye, so when designing packaging machinery, computer-controlled cameras and detectors are often used to distinguish the packaging material thickness and material changes. The camera has now developed to be able to check and identify the pictures taken by the camera and display them on the display. At present, the speed of the machine cannot be changed during processing. In the future, the speed should be changed according to the change of the material, 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 clean.
Improve productivity, reduce costs, and meet production requirements to the maximum
German packaging machinery, especially food packaging machinery, has the characteristics of high-speed complete set, high degree of automation and good reliability. Increasing the speed of the machine is a complicated problem. The faster the speed, the lower the production cost of a single piece, but the area of ??the plant increases. In addition, the motor speed is also limited, so you can't think of it as fast as you can. Generally speaking, increasing the speed by 15%~20% will bring a series of complicated problems.
In addition to increasing the speed, increasing productivity can also be solved through other channels:
①Adopt continuous work or long work. There are intermittent and continuous working methods for packaging machinery. When designing, you should strive to design for continuous work, which will increase productivity. There can also be multiple production lines in a device to produce the same product or several different products, but Reliability must be improved.
②Reduce the scrap rate and provide a fault analysis system. The loss caused by waste products is huge, not only the loss of products, but also the loss of materials. Therefore, it is necessary to vigorously reduce the scrap rate; when the packaging machinery is sold, it should also provide a fault analysis system for maintenance services, that is, modal analysis to find faults, or remote diagnosis through the Internal network to maximize customer satisfaction. In the future, the packaging machinery will be further intelligentized, that is, the equipment will find faults by itself and solve the faults by itself, so as to reduce the scrap rate and the fault rate, so that the normal productivity can be improved.
③ Integrate product production machinery and packaging machinery. Many products are packaged at the end of 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 productivity with each other. Among them, packaging machinery often becomes the bottleneck of production, so it is necessary to provide equipment with different productivity.
Adapt to product changes, design equipment with good flexibility and flexibility
In order to make the packaging machinery have good flexibility and flexibility, and improve the degree of automation, a large number of microcomputer technology, module technology and unit combination must be used. In order to adapt to changes in packaging product varieties and packaging types, the flexibility and flexibility of packaging machinery and equipment are often manifested in the following three aspects:
①Flexibility of quantity. It can not only package a single product, but also adapt to the packaging of different batches of products
② Flexibility of construction. The whole equipment is composed of units, and one or several units can be used to adapt to product changes.
③Flexibility of supply.
Units are used to combine and supply the units. For example, candy packaging machines, on a common basis, combine different units, three feed ports, and four different folding packaging forms, so that one machine can be simultaneously Pack 8~10 different kinds of sweets. Operated by multiple manipulators, under the supervision of a camera, it directs its actions and packs different types of candies in different ways according to instructions. If the product changes, just change the program in the camera, so that the device has good flexibility and flexibility.
Provide complete equipment
German packaging machinery design, based on user needs, provides structural and economical complete system solutions for production enterprises, and uses computer simulation technology to demonstrate operations to users, and modify them after soliciting user opinions. When providing users with automatic production lines or production line equipment, special attention is paid to the integrity of the complete equipment. Whether it is high-tech, high-value-added equipment, or simpler equipment, they are provided according to the requirements of matching.
German packaging machinery manufacturers will also provide complete equipment as their own goal. For example, a beverage filling line has more than 200 microcomputer parts, many pipeline display screens, and more than 100 software programs that control various packaging actions. In order to meet the production rate of 1200 bottles/min, two lines must work together, so the production of the entire beverage filling line needs to occupy half the area of ??the football field, and all equipment can be installed in one factory. Think of a major weakness in my country's current packaging machinery production is the production of more single machines, and fewer complete assembly lines; more mainframes, fewer auxiliary machines, poor compatibility. This German approach is worthy of our reference.
Using computer simulation design technology
As the speed of new product development continues to accelerate, German packaging machinery design generally uses computer simulation technology, that is, various machine elements are stored in the computer in the form of a database, and the drawings are digitized into the computer, and the computer can be automatically synthesized into a three-dimensional model. Then enter the actual production data and indicators, enter various possible failures, the computer three-dimensional model can be modeled on the actual working conditions, and demonstrate how much productivity can be achieved, how many waste products, each link of the production line Whether it can match production, where is the bottleneck, the customer can see at a glance according to the curve displayed on the display, and can modify the model according to the customer's opinion. The computer synthesis is very fast, so the modification work is quick and convenient until the customer or designer is satisfied. Using computer simulation design technology greatly shortens the development and design cycle of packaging machinery.
Packaging machinery design must not only pay attention to its function and efficiency, but also pay attention to its economy. However, the economic efficiency is not entirely the cost of the mechanical equipment itself, and more importantly, the operating cost, because the depreciation of equipment only accounts for 6% to 8% of the cost, and the other is the operating cost.
