Packaging machinery design trend research 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' requirements for mechanical performance are getting higher and higher, mainly in the following aspects:
1. High productivity to meet the requirements of delivery time and reduce the cost of process circulation; for some products, packaging machinery and production machinery are also required to be connected.
2. To meet the needs of product renewal, packaging machinery should have high flexibility and flexibility.
3, equipment failure, there is a fault to enable remote diagnosis services.
4. Less pollution to the environment, including noise, dust and waste pollution.
5, purchase equipment investment as little as possible, the price should be as low as possible.
German packaging machinery manufacturers and design departments have taken the following measures to meet the above customer requirements:
First, improve the automation of the process
A few years ago, automation technology only accounted for 30% of packaging machinery design, and now accounts for more than 50%, using a large number of microcomputer design and mechatronics control. The purpose of improving the automation degree of packaging machinery is to improve productivity; the second is to improve the flexibility and flexibility of the equipment; the third is to improve the ability of the packaging machinery to complete complex operations, that is, to complete the packaging process using a robot. Today's focus:
? Domestic iron ore price starts negotiations continue
China's abrasive products market prices are stable and frequent transactions
? New type of drill bit for cutting stainless steel
? Building materials prices continue to rise
For example, the packaging of chocolate candy has already realized the replacement of the original manual with a robot.
Packaging machinery automation design has two main features:
1. Each robot is controlled by a separate computer
A packaging machine needs to be completed by multiple robots in order to complete complex packaging operations. When the packaging operation is completed, under the information and monitoring of the camera controlled by the computer, the robot completes the specified actions according to the instructions of the computer program to ensure the quality of the packaging.
2, with high resolution of material and thickness
In the packaging process, the thickness and material changes of the packaging materials are not easily discernible to the human eye. Therefore, computer-controlled cameras and detectors are often used in the design of packaging machinery to distinguish the thickness of the packaging material and the material changes. The camera has now evolved to be able to self-check and discern the picture of the camera and display it on the display. At present, the speed of the machine can not be changed during processing. In the future, the speed should be changed according to the change of the material, so that the speed can be controlled in the optimized state, and the packaging process can be completed in a short time, and the automatic cleaning and automatic disinfection can be realized. And automatic cleaning.
Second, improve productivity, reduce process costs, Zui meets production requirements to a large extent
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 12,000 / minute. Increasing the speed of the machine is a complicated problem. The faster the speed, the lower the production cost per piece, but the floor space of the plant increases.
In addition, the motor speed is limited, so you can't think how fast. In general, a 15-20% increase in speed will introduce a series of complex problems.
In addition to increasing the speed of production, you can also try to solve it from another channel:
1, using continuous work or multi-head work
The working mode of packaging machinery is intermittent and continuous. When designing, it should strive to design continuous operation, which will increase productivity. There can also be multiple production lines in one equipment to produce the same product or several different products, but Reliability must be improved.
2, reduce the scrap rate, provide fault analysis system
The damage caused by waste products to production is enormous, not only product loss, but also material loss. Therefore, we should try our best to reduce the scrap rate; when the packaging machinery is sold, it should also provide a fault analysis system for the repair service, that is, perform modal analysis to find faults, or remotely diagnose through the Inter network, and Zui can meet the needs of customers to a large extent. In the future, the packaging machinery should be further intelligent, that is, the equipment itself should look for faults and solve the faults themselves to reduce the scrap rate and the failure 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 also helps to increase the productivity of the product. 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. The packaging machinery often becomes the bottleneck of production, so it is necessary to provide different kinds of productivity equipment.
Third, adapt to product changes, design equipment with good flexibility and flexibility
Many packaged products are becoming more and more competitive in the market, and the cycle of replacement is getting shorter and shorter. For example, the production of cosmetics has changed in three years, even in a quarter, and the production volume is very large. Therefore, packaging machinery is required to have 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 economy. Sexual requirements.
In order to make the packaging machinery have good flexibility and flexibility, and to improve the degree of automation, it is necessary to use a large number of microcomputer technology, module technology and unit combination. In order to adapt to changes in the variety of packaging products and packaging types, the flexibility and flexibility of packaging machinery and equipment often appear in the following three aspects:
1, the amount of flexibility
It can pack individual products as well as packaging for different batches.
2, the flexibility of construction
The whole equipment is made up of units, and one or several units can be used to adapt to changes in the product.
3. Supply flexibility
Using a combination of units, the units are combined and supplied together, such as a candy packaging machine, on a common basis, combining different units, three inlets, four different folding packages, so that one machine can simultaneously Pack 8-10 different sweets. It is operated by a plurality of robots, under the supervision of a camera, directing its actions, and packaging different types of candy in different ways according to the instructions. If the product changes, just change the program inside the camera, so that the device has good flexibility and flexibility.
Fourth, provide complete sets of equipment
Germany's packaging machinery design, based on the user's needs, provides a structural and economical complete system solution for the production enterprise, and uses the computer simulation technology to demonstrate the operation to the user, and solicits the user's opinion and then modifies it. When providing users with automatic production line or production line equipment, they pay special attention to the integrity of complete sets of equipment. Whether it is high-tech, high value-added equipment or simple equipment, it is provided according to the matching requirements.
German packaging machinery manufacturers will also provide complete sets of equipment as their goal. Such as a beverage filling line, there are more than 200 micro-computer parts, there are many pipelines, display screens, there are more than 100 software programs to control various packaging actions. In order to meet the productivity of 1200 bottles / hour, two lines must work together, so the production of the entire beverage filling line takes up half of the area of ​​the football field, and all equipment is required to be in one manufacturer. Lenovo has a big weakness in the production of packaging machinery in China, which is the production of more single machines, and fewer sets of assembly lines; more hosts, fewer auxiliary machines, and poor matching. This practice in Germany is worth learning from.
Fifth, the general use of computer simulation design technology
With the speed of new product development, the German packaging machinery design generally uses computer simulation technology, which means that various machine elements are stored in the database in the form of a database. After digitizing the drawings and inputting into the computer, the computer can be automatically synthesized into a three-dimensional model. Then input the data and indicators in actual production, and input all kinds of possible faults. The computer 3D model can be operated according to the real working conditions, demonstrating what the productivity can be achieved, how much waste is, and the production line is five. Whether a section can match production, where the bottleneck is, allows the customer to see the curve displayed on the display at a glance, and can modify the model according to the customer's opinion. Computer synthesis is fast, so modifications can be quick and easy until the customer or designer is satisfied. The use of computer simulation design technology has greatly shortened 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. But economics is not entirely the cost of mechanical equipment itself, but more importantly, operating costs, because equipment depreciation costs only account for 6-8% of the cost, the other is the operating costs.
