1 automation technology
1.1 Fieldbus technology
The use of fieldbus technology first "liberated" most of the hardware, simplifying the cumbersome installation process. In the actual process of production application, convenience and flexibility are more obvious; fieldbus technology can be integrated with ERP system, so that the management can easily retrieve and analyze the operational data through the ERP system to understand the actual production and Monitor the operation of the shop floor in real time. Fieldbus technology is widely used in large food processing enterprises, which facilitates the unmanned operation of the entire production line and the seamless connection of transmission and inspection processes.
1.2 Sensor Technology
In the food processing and food machinery industry, there are many applications for sensors. Sensors are used in the monitoring, filling, packaging, mixing and processing, cooling and heating, cleaning, packaging and other processes of food and beverage storage tanks.
1.3 Transmission Control Technology
The use of transmission products in food machinery is mainly to adjust the process speed and control the cyclical changes of the motor speed in the production process. However, for most food machinery, the frequency converter is not a mandatory electrical product. The frequency converter has a low utilization rate in the industry, and there is a large room for development in the packaging production line of large standard specifications.
1.4 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, unloading, conveying, marking, palletizing, depalletizing and other processes.
1.5 human machine interface technology
The HMI of the food machine is usually used in conjunction with a PLC or a single-chip microcomputer to set production process parameters, monitor the operating status of the equipment, and record the data produced by the equipment. A few high-end machines use touch screens.
1.6 Logistics Automation Technology
The further development of logistics automation has improved the entire food processing and packaging production line, and a complete food processing chain has been formed. The most direct manifestation of logistics automation technology is to save manpower. Although China's labor force is relatively abundant, the development of logistics is the general trend.
1.7 automatic identification technology
Automatically identify the thickness, hardness, rebound force, etc. of the packaging material, and feedback to the robot to adjust the action amplitude through the computer to ensure no rebound; at the same time, ensure that various products are packed into the same box, and the arrangement is regular. Since the product delivered by the production line is disordered, probe scanning is required to determine the position of the material in different shapes and then fed back to different robots so that it can accurately and accurately place the item in the tray in the correct position and orientation.
1.8 safety detection technology
The detection technology in the food processing and packaging process is not limited to the detection of impurities on the production line. As the importance of food inspection is gradually increased, the automation technology will be further expanded in the application field of detection technology.
Second, summary
Driven by the continuous improvement of food processing technology, the automation level of food packaging has also shown a trend of rapid increase. Nowadays, the development and development of food machinery is advancing in the direction of diversified functions, intelligent control, and rapid development. The application range of microelectronics, intelligent, industrial robots, image sensing technology, and computers will become more and more important. Wide, and the pneumatic technology used in food machinery is bound to develop in a networked and intelligent direction.
