Title: On-line quality inspection technology of filling line and its application

Introduction:

With the development of industrial automation, the automation of production lines is getting higher and higher. Filling line, as an important production line equipment, is used for the filling and packaging of liquid or solid materials. In the filling process, quality inspection is a crucial link. The traditional quality inspection method requires manual participation, which is not only time-consuming and laborious, but also has certain uncertainty. For the production line with larger scale, more varieties and higher output, how to improve the efficiency and accuracy of quality detection has become an urgent problem to be solved. This paper will discuss the on-line quality inspection technology and its application, analyze its advantages and limitations, and look forward to its development prospects.

First, the principle of filling line online quality detection technology

1. Sensor technology

The key of on-line quality inspection of filling line is real-time monitoring and measurement. Sensor technology can be monitored in real time by sensing the physical characteristics of the material being measured, such as weight, volume, pressure, etc. Commonly used sensors include load sensors, flow sensors, pressure sensors and so on. These sensors can transmit measurement data to intelligent control systems such as computers or PLC to realize online monitoring and discrimination of product quality.

2. Image recognition technology

Image recognition technology is another key technology in on-line quality inspection of filling line. Product images are obtained by cameras and other equipment, and feature extraction and analysis are carried out by image processing algorithms to realize product quality detection and discrimination. For example, image recognition technology can be used to detect key indicators such as packaging tightness, liquid level height, and bubble conditions, thereby avoiding the appearance of defective products.

3. Data analysis and discrimination technology

Online quality inspection not only needs real-time monitoring and measurement, but also needs to analyze and distinguish the data. Data analysis and discrimination technology can be used to process data through model building, feature extraction, statistical analysis, etc., so as to realize product quality discrimination and classification. For example, data collected by sensors can be trained by machine learning algorithms, quality detection models can be established, and online quality detection can be automated and intelligent.

Second, the application of filling line online quality detection technology

1. Monitoring of filling process

The on-line quality inspection technology of filling line can monitor and control key parameters such as liquid level height, flow rate and pressure in real time during the filling process to ensure product quality meets the standard. For example, during the beverage filling process, the flow of the beverage can be detected in real time through the flow sensor, and the operating state of the filling machine can be adjusted according to the preset filling speed and capacity to ensure that the filling amount of each bottle of beverage is uniform.

2. Quality identification and classification

The on-line quality inspection technology of filling line can distinguish and classify product quality through image recognition and data analysis. For example, in the food filling process, the integrity and tightness of the product packaging can be detected through image recognition, and damaged and leaky products can be eliminated; At the same time, the weight of the product is monitored by the weighing sensor, and the excess and insufficient products are identified to ensure that the product quality meets the requirements.

3. Anomaly detection and early warning

The on-line quality inspection technology of filling line can detect abnormal situation and give early warning in time through real-time monitoring and data analysis. For example, during the liquid filling process, if abnormal conditions such as the liquid level exceeding the preset range or bubbles are detected, the system can automatically stop and issue an alarm to prevent further expansion of product quality problems.

Third, the advantages and limitations of filling line online quality detection technology

Step 1: Advantages

The on-line quality inspection technology of filling line can realize real-time monitoring and automatic discrimination, which greatly improves the efficiency and accuracy of quality inspection. Through data analysis and early warning function, quality problems can be found in time to avoid the generation of defective products and waste products. At the same time, the filling line online quality inspection technology can achieve automated and intelligent production processes, reducing labor costs and the risk of human error.

2. Limitations

The successful application of on-line quality inspection technology in filling line requires comprehensive optimization of equipment and algorithm. On the one hand, the performance and stability of the sensor have an important impact on the quality detection results; On the other hand, the accuracy and real-time performance of image processing algorithms are also key factors. In addition, due to the different characteristics of liquids and solids, different types of products may require targeted online quality inspection solutions.

Fourth, prospects

With the continuous development of Industry 4.0 and artificial intelligence technology, the online quality inspection technology of filling line will be more widely used. In the future, through the connection with other intelligent devices and systems, the online quality inspection technology of the filling line can realize real-time data interaction with information systems such as ERP (enterprise resource planning) and MES (Manufacturing execution System) to achieve comprehensive monitoring and optimization of the production process. In addition, the online quality inspection platform based on cloud computing and big data technology will also gradually mature, providing greater convenience and feasibility for the online quality inspection of the filling line.

Conclusion:

Filling line on-line quality inspection technology is one of the important applications of industrial automation, its principle is mainly based on sensor technology, image recognition technology and data analysis and discrimination technology. Through real-time monitoring and measurement, the product quality can be detected and judged online. Through the analysis of its application, this paper points out the advantages and limitations of the on-line quality inspection technology of filling line, and looks forward to its future development prospects. With the continuous progress and innovation of technology, the online quality inspection technology of filling line will be further developed to provide more efficient and accurate quality control means for production enterprises.
