Application of automation technology in food packaging machinery

Application of automation technology in food packaging machinery


As we all know, the traditional food machinery automation technology only installs a programmable logic controller PLC on all-mechanical equipment, which is mainly used to control the mechanical power shaft and logic function of the drive, but the equipment Poor stability and flexibility. Due to the variety of products and the short life cycle of food, food packaging machinery and equipment must have strong stability and flexibility. The function of the second-generation automation equipment developed later was transferred from the mechanical power shaft to the electronic drive system, and the PLC system was used to control the logic function. Compared with the first generation of automation equipment, the second generation of automation equipment is significantly more advanced, and today's third generation of automation equipment uses fully electronic technology, the most critical technology among which is control and drive technology. The automated food machinery combines sound, life, machine, magnetism, beauty, electricity, technology and light. It is a highly intelligent and high-tech product. The automation products used in food machinery mainly cover several categories such as transmission control, machine vision, human-machine interface, control system, motion control, and sensors. 

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. Guangdong Kenwei combination scale and counting machine, in the remote system and visual automatic identification application, is quite representative in China. 

1.8 security 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. 

2.Automation technology application 

2.1 Open and flexible interface design      

An open system can be connected to various sensors, instrumentation, and security systems. This includes not only the interconnection between devices, but also the interconnection capabilities of the upper EIKP/MES, CIMS, etc., including open interfaces such as oPcServer. , connection to the database, etc. 

2.2 Flexible hardware design      

First of all, there must be a complete product line to meet the needs of various control systems. For example, B&R's GMC includes control for synchronous servo, asynchronous servo, DC, stepping, hydraulic, etc., and also includes the support capabilities of the robot. 

2.3 Flexible production     

Due to the enormous changing ability of food packaging objects, the flexibility of the production system poses a huge challenge. On the one hand, the process needs to be switched quickly, on the other hand, there is no need to design a new machine for a new production, which is reflected in the production system. Adaptation range, and the flexibility of the production system is not    It is only reflected in the optimization of the organization and process of the production plant. On the execution side, the automation system provides rapid process switching and the expansion of the production range. 

2.4 Security Technology     

As end users and the government pay attention to personal safety, the security of the system must be taken seriously. 

3.pneumatic technology application       

Most of the packaging work in food processing, especially the more complicated packaging process, is basically manual, which is very likely to cause pollution to the packaged product. This situation needs to be changed. At present, the state has stepped up efforts to implement the food quality and safety market access system, and food equipment is gradually being incorporated into the food quality and safety system. One of the basic components is pneumatic technology. Pneumatic technology, with high speed and efficiency, clean and safe, low cost, easy maintenance, etc., is playing an increasingly important role in food packaging and production process, beverage and beer filling machine, jelly filling and packaging machine, filling machine , meat packaging machines, etc. are used in large quantities, which can shorten the processing auxiliary time, reduce the labor intensity of workers, and give full play to the high efficiency of equipment. In food production, different production areas have different requirements for hygiene. The environment of food processing machinery is defined as three working areas, food area, splash area and non-food area. According to different areas, the pneumatic technology required and The products are not the same. In the food zone and splash zone, pneumatic technology is mainly used in distribution, bottling, forming, filling, dispensing, sealing, etc., because pneumatic components need to be directly or indirectly in contact with the main production materials, in order to prevent the production of the final product. The possibility of pollution shall be non-toxic, non-absorbent and corrosion-resistant stainless steel; if aluminum alloy is used, it shall have certain corrosion resistance, non-toxicity and non-absorption; rubber products used inside the components such as seals Parts and the like shall comply with the corresponding sanitary requirements. In the working environment, it shall have heat, acid, alkali and oil resistance. It shall be properly cleaned and disinfected, insoluble, non-toxic, non-absorbent, and shall not affect the smell of the product. The working air filter device shall ensure that no dust above 5 ixm is allowed to pass; the structure and surface shall be smooth, durable, easy to clean and achieve a good cleaning effect. Typical pneumatic products used in these two environments are stainless steel cylinders, clean cylinders, easy-to-clean valve islands, stainless steel air handling components, and the most representative of these are clean cylinders. Non-food area, in which pneumatic technology is mainly used in packaging, packaging, labeling, testing, capping, etc., although the pneumatic components in this area do not need to be in contact with the production materials, they still need to be standardized and easy to clean. , intelligent and environmentally friendly, compact structure and so on. 


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. In fact, most of the failures of pneumatic systems are derived from the air handling system, but due to the lack of feedback and monitoring of the state, there are a lot of shortages in the traditional sense of gas source treatment. For example, the pressure regulating valve is not normal, the filter Problems such as filter plugging, these problems have brought great problems to the normal turnover and operation of the entire pneumatic system. To this end, intelligent triplex has emerged as the times require, it can promptly inform whether to change the lubricating oil, filter element, record the use time and pressure status, minimize the repair and maintenance costs and the probability of failure, and enhance the production capacity of equipment and system. Normal operating time.
