Machine-vision-based online grading and packaging production line for bananas

Abstract

The invention relates to a machine-vision-based online grading and packaging production line for bananas. The production line comprises a conveying device, a grading device, a cleaning and refreshing device and a packaging device, wherein the grading device and the cleaning and refreshing device are connected with the packaging device through the conveying device. According to the machine-vision-based online grading and packaging production line for the bananas, appearance qualities such as shapes, sizes, colors and defects of the cleaned and dried bananas can be detected by a computer vision system in the grading device; besides, the detections on conventional physical and chemical indicators such as textures, pH and soluble solids of the bananas can be realized by exchanging light sources in an illumination box (e.g., by adopting lasers, ultraviolet rays and the like); the grade, grade information and position information, acquired by a position sensor, of the bananas can be determined by an industrial personal computer (IPC) through synthesizing the appearances and the physical and chemical indicators and can be transmitted to a grading execution module; the bananas in different grades are sorted to corresponding fruit discharging chutes by the grading execution module and enter the packaging device to be contained into boxes; and the bananas can be subjected to postharvest batch detecting, grading and packaging, so that the industrial automation level of the bananas is improved.

Description

technical field [0001] The invention relates to an on-line grading and packaging line for bananas, in particular to an online real-time detection, grading and packaging of whole bananas. Background technique [0002] Banana is one of the four major fruits in the world, an important source of nutrition for more than 4 billion people in the tropics, and occupies a very important position in the international fresh fruit market. China is a major producer of bananas. In 2006, China's banana output was 6.8994 million tons, ranking third in the world, second only to India and Brazil. By 2010, my country's banana output reached 8.1 million tons. However, the automation level of China's banana industry is low, and the post-harvest processing operations are basically completed manually, which greatly hinders the development of China's banana industry. [0003] In the field of fruit grading, there are gap type grading devices (patent application numbers: 200910028948.7; 200520081227....

AI Technical Summary

Problems solved by technology

[0004] Due to the particularity of the banana shape and packaging form, many of the above-mentioned automatic packaging equipment for round or nearly round fruits cannot be applied to the packaging of bananas, although the foreign patent PCT / AU2010 / 001218 describes a Banana fruit refers to packaging equipment, but it is not suitable for packaging a handful of bananas
