Analyze the new trend of packaging machinery automation

China Packaging Machinery Industry Status

Packaging machinery refers to machinery that can complete all or part of the product and product packaging process. The packaging process includes major processes such as filling, wrapping, and sealing, as well as related processes such as cleaning, stacking, and disassembling. In addition, it also includes the steps of measuring or stamping the package.

After more than 20 years of development, China's packaging machinery has become one of the ten industries in the machinery industry, providing effective protection for the rapid development of China's packaging industry. However, at present, the export value of packaging machinery in China is less than 5% of the total output value, but the import amount is roughly equivalent to the total output value, which is far from the developed countries. The packaging machinery industry lacks leading enterprises. There are not many enterprises with large production scale and high product quality. According to statistics from the Food and Packaging Machinery Industry Association, there are currently more than 3,600 packaging machinery manufacturers in China, but only 20 of them currently have output value and sales exceeding RMB 100 million.

China still stays at the test imitation stage, has weak self-development capabilities, and lacks a pilot base for scientific research and production. Statistics show that there are only 1,300 kinds of packaging machinery in China, and the number of supporting machinery is small. There is a lack of high-precision and large-scale chemical products that cannot meet market demands. The gap in product quality is manifested in low product performance, poor stability and reliability, and unsightly appearance. Rough surface treatment, poor quality of many components, short life, and low reliability affect the overall product quality.

New trends in the development of packaging machinery

With the continuous development of science and technology, the emergence of a variety of food processing products, put forward new requirements for packaging technology and packaging equipment, packaging machinery in the circulation field is playing an increasingly larger role. At present, the competition for packaging machinery is becoming increasingly fierce, and highly automated, intelligent, multi-functional, high-efficiency, and low-consumption packaging equipment are increasingly favored by the industry.

Since the beginning of the 21st century, compared with traditional packaging machinery, new packaging machinery has been characterized by simplification, high productivity, better matching and automation. The future packaging machinery will cooperate with the trend of industrial automation and promote the overall level of packaging equipment. For example, high-intelligence digital control systems, encoders and digital control components, and power load control devices have been commonly used in packaging machinery and equipment to make equipment users more independent, flexible, accurate, and high in operation. Efficiency and compatibility.

It is understood that the countries with high levels of foreign packaging and food machinery are mainly the United States, Germany, Japan, Italy and the United Kingdom. Germany's packaging machinery is leading in design, manufacturing and technical performance. In recent years, there has been a new trend in the development of packaging and food machinery equipment in these countries.

Process automation is getting higher and higher. At present, automation technology has accounted for more than 50% of the packaging production lines. A large number of computer designs and electromechanical integration controls are used to increase productivity, flexibility and flexibility of the equipment, and robots are added to complete complex packaging actions. Each robot is controlled by a separate computer. The camera monitors the packaging action and feeds the information back to the computer to adjust the range of motion to ensure the quality of the package.

Achieve packaging machinery automation technology <br> <br> packaging machinery mechanical, electrical, optical, acoustic, magnetic, chemical, biological and beauty as one of the high-tech, highly intelligent, highly competitive products. It is a major feature of its rapid development and fast update speed. All high-tech products in the world can be applied. The automation products used in packaging machinery mainly include control systems, transmission control, motion control, machine vision, human-machine interface and sensors, including: control systems (embedded products, PLC, IPC, fieldbus), and transmission control. (inverter, DC speed control), motion control (servo, stepper motor, motion controller), man-machine interface (text display, touch screen, tablet computer), electrical components and sensors (temperature sensor, pressure sensor, photoelectric switch, Travel switches, RFID, etc.) and machine vision (remote monitoring, industrial cameras). Specifically, it mainly involves the following kinds of automation technologies:

(1) Fieldbus technology . The use of fieldbus technology first "liberated" most of the hardware, making the tedious installation process easier; in the actual process of production applications, the convenience and flexibility are more obvious; the fieldbus technology can be integrated with the ERP system, so management The layer can easily access and analyze operational data through the ERP system to understand actual and immediate production conditions and monitor the operation of the plant. Fieldbus technology is widely used in large-scale food processing companies in China, which facilitates the seamless integration of the unmanned operation of the entire production line, as well as the transmission and detection processes.

(2) Sensor technology. In the food processing and packaging machinery industry, sensors have a wide range of applications. Sensors are used in the monitoring, filling, mixing and processing of food and beverage storage tanks, cooling and heating, cleaning, and packaging. The gap in the technology application market has become a must for many automation vendors.

(3) Transmission control technology. The use of transmission products on packaging machinery is mainly to adjust the main process speed and to control the periodic changes in motor speed during production. However, for most packaging machines, the inverter is not necessarily an electrical product. The use of frequency converters in the industry is low, and there is ample room for development in large-scale standard machines and packaging production lines.

(4) Motion Control Technology . The application of motion control products on the packaging machine is mainly to achieve precise position control and strict speed synchronization, for loading and unloading, conveying, marking, palletizing, depalletizing and other processes. Due to the rapid development of China's packaging industry, China will need more high-end packaging machinery, and motion control products will gain greater room for development in the industry.

(5) Human-machine interface technology. The HMI of a packaging machine is usually used in conjunction with a PLC or a microcontroller to set production process parameters, monitor equipment operating status, and record equipment production history. A few high-end machines use touch screens.

(6) Logistics Automation Technology. With the further development of logistics automation, the entire food processing and packaging production line has been perfected, and a complete food processing chain has been formed. The most direct manifestation of logistics automation technology is to enable manpower to save. Although China's labor force is more abundant, the development of logistics is the general trend.

(7) Automatic identification technology. Automatically identify the thickness, hardness, rebound force, etc. of the packaging materials, and feedback the robot to adjust the movement range to ensure that there is no rebound; at the same time, ensure that all kinds of different products are packed in the same box, and the arrangement is regular. Since the products delivered by the production line are disordered, then the probe scan is needed to determine the position of the different shapes of the material and then fed back to the different robots so that it will accurately place the articles in the tray in the correct position and orientation.

(8) Safety inspection technology. The detection technology in the food processing and packaging process is not limited to the detection of impurities in the production line. With the increasing emphasis on food inspection, the application of detection technology has been further expanded. In machine vision products, color machine vision products are more prominent in food detection applications.

In summary, the packaging industry is a supporting industry, involving many areas of the national economy, especially the food industry and beverage industry, but also depends on the technological progress and supporting services of the packaging industry. Therefore, we cannot ignore the backwardness of packaging machinery. Efforts to actively promote the packaging industry to embark on the automated path of rapid and healthy development.
