A roller-type fruit conveying mechanism that turns fruits of different sizes at the same angular velocity

Abstract

The utility model relates to a roller type fruit conveying mechanism which turns over fruits of different sizes at the same angular velocity. The roller adopts an integral double-cone concave structure, the generatrix equation of the rolling body is (C is a constant, r0 is the minimum rolling body radius), and the horizontal roller shafts extending perpendicular to the conveyor chain are installed parallel to each other at a certain distance. On the chain, the rollers are fitted on the roller shafts, and the fruit is supported between two adjacent rollers. When the conveyor chain rotates, the rollers move forward together with the roller shafts, and the rollers in the image acquisition area rotate around the roller shafts due to the friction of the friction surface below them, and drive the rollers on them. Fruit flips and rolls. As long as the radius R≥r0 / C of the fruit, the fruit whose size differs nearly twice can be reliably transported by the mechanism and turned over on the roller at the same angular velocity. After proper optimization of design parameters, the invention can be widely used in the transportation and machine vision sorting of quasi-spherical fruits such as apples, citrus, peaches, tomatoes, big cherries and winter jujubes.

Description

Technical field [0001] The invention relates to a roller-type fruit conveying mechanism used in a fruit machine vision automatic sorting machine, especially a kind of quasi-spherical fruit that can transport nearly double the size of the fruit, and makes the fruits of different sizes be transported according to the same time. A roller type fruit conveying mechanism that turns over on rollers at the same angular velocity. Background technique [0002] In recent years, in order to improve the commodity value of fruits and meet the increasing consumption demand of consumers, fruit production and distribution enterprises have adopted various methods to grade fruits. Among them, the fruit machine vision automatic sorting machine, which uses computer vision technology to classify according to the appearance quality of fruit size, color, fruit shape and surface defects, has been extensively studied, and has gradually entered the market, showing good application prospects. The frui...

However, this conclusion has little guiding significance for practical applications. In practical applications, the size of fruits to be sorted often changes within a large range. However, due to the limitation of image processing speed and the requirements of sorting machine sorting speed, It is impossible to collect too many images for each fruit, and the grading error caused by the corner error is difficult to overcome
