China has always been a large country of alcohol consumption, and Baijiu, beer, beverages, etc. account for a large proportion of residents' daily consumption. Therefore, there are many distilleries all over the country, making wine day and night to ensure residents' consumption demand. There are many famous liquors in the country, such as Maotai, Jinjiu, Luzhou Laojiao, Sichuan, etc.
Throughout the major wineries across the country, the vast majority still use the traditional brewing process many years ago, and the quality of the wine is very good, but the vast majority of wineries still use the manual feeding method in production: some winery workers use shovel to frequently sprinkle materials into the pot again and again, and the degree of automation is very low; Although some wineries realize machine feeding, the flatness cannot be guaranteed, and it needs to be adjusted manually.
These are mechanical repetitive labor. The labor intensity of workers is very high. Each distillery has many workshops and many pots to produce every day. The factory needs to hire many workers. Not only the labor cost is very high, but also the production efficiency cannot be guaranteed. Many distillery workshops have outdated equipment, and the wine steamer is erected on a high table. The space is narrow, the working environment is poor, and the operation is both troublesome and dangerous. Under the current situation that the consumption demand of Chinese people for alcohol is increasing and the requirements for wine quality are higher and higher, how to reduce production costs, labor costs, improve production environment, enhance automation and improve production efficiency has become an urgent problem for major wineries.
With the development of science and technology and the rapid development of economy, the traditional manual production has been far from meeting the consumer demand. The way of using robots to automatically load steamers has become the same choice for major distilleries. At present, the international trend is to adopt the detection system based on machine vision, use image processing, analysis and recognition technology to judge the temperature of the material surface in the feeding process, and then combined with the experience of manual production, use the visual guidance system of the steamer feeding robot to control the feeding position and discharge volume, so as to meet the requirements of steam volume and flatness in the feeding process, and the most important thing is to meet the requirements of production process, Ensure the quality and output of wine.
Infrared thermal imaging can image and measure temperature, which can assist the steamer loading robot to improve production efficiency.
The thermal imager is installed on the rotatable paving head, and the method of multi-point image acquisition and splicing is adopted to realize the collection of the surface temperature information of the material layer of the retort barrel; Through the two-level screening method of image region segmentation, threshold processing and feature point matching, the image mosaic method is optimized and improved, which improves the real-time and accuracy of image mosaic.
System architecture of steamer loading robot:
Schematic diagram of steamer loading robot system:
The temperature field acquisition and analysis system of the liquor making material layer detects the surface temperature of the liquor making layer based on the infrared thermal imaging thermometer, analyzes its gradient distribution and the central coordinates of each temperature gradient area, and transmits it to the control system. According to the instructions of the control system, the steamer loading robot works together with the fermented grain conveyor to send the liquor making material to the designated laying point to complete the laying of the liquor making material in the designated area.
Application cases: Jinjiu, Maotai, liuqixiang, Fenjiu, Gujing gongjiu, etc
Infrared thermal imager selection:
A steamer robot is installed at the distillation place, which can automatically add fermented grains according to the situation in the steamer; Real time monitoring of the temperature of the distiller's grains and alcohol steam in the barrel. Once steam is found in the area, it can be linked with the steamer loading robot at the first time to automatically fill the air leakage point with the distiller's grains; The infrared thermal imager is installed at the mechanical arm through the thermal imager to monitor the temperature of the distiller's grains and alcohol vapor in the steamer barrel in real time. Once the regional vapor is found to emerge, it can be linked with the steamer loading robot to automatically fill the air leakage point with the distiller's grains. Through the analysis of the temperature of the fermented grains in the steamer by the infrared thermal imager, it is predicted that the steam is about to emerge, the fermented grains are accurately measured, the temperature is properly controlled, and the distillation efficiency, liquor yield and liquor quality are greatly improved.
Different types of infrared thermal imagers can be selected according to actual needs: K23 series and k26 series online infrared thermal imaging thermometers are recommended.
