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.
