Free conveying type fruit and vegetable sorting device and sorting method thereof

Abstract

The invention discloses a free conveying type fruit and vegetable sorting device and a sorting method thereof. The free conveying type fruit and vegetable sorting device comprises a conveyor and a tray. The tray is located on the conveyor. The free conveying type fruit and vegetable sorting device further comprises a recognizer, a distance measuring assembly, a controller, an upper computer, a sorting assembly and a discharging roller way. The recognizer and the distance measuring assembly are arranged on the upstream of the conveyor. The tray is provided with an identification tag. The sorting assembly and the discharging roller way are arranged on the downstream of the conveyor. The sorting method comprises the following steps that firstly, the conveyor conveys the tray; secondly, the upper computer inputs fruit and vegetable ranked data to the controller; thirdly, an initial position of the tray is acquired through a proximity switch, and the recognizer sends the identification information to the controller; fourthly, the controller matches the fruit and vegetable ranked data with the identification information, and the sorting position of the tray is determined; fifthly, an encoder inputs conveying distance into the controller in real time; sixthly, when the tray arrives at a sorting position, the controller controls the sorting assembly (8) to work, and fruit and vegetablesorting is completed. By means of the free conveying type fruit and vegetable sorting device and the sorting method thereof, the fruit and vegetable sorting efficiency is improved, and secondary manual sorting at the later period is avoided.

Description

technical field [0001] The invention relates to a fruit and vegetable sorting device, in particular to a free conveying type fruit and vegetable sorting device and a sorting method thereof. Background technique [0002] The fruit tastes sweet and sour and is rich in nutrition. It is deeply loved by the public. Vegetables are an indispensable food in the daily diet of our people. Due to the limitation of the growth environment and the supply of nutrients, the size of the fruit and vegetable products is uneven, and the taste and quality are different. Therefore, grading and selling harvested fruits and vegetables can significantly increase the economic value of fruit and vegetable products while meeting the needs of different consumers. At present, the foreign fruit and vegetable sorting technology is relatively advanced, which can realize the rating and sorting of a series of indicators such as size, weight, internal quality and external quality according to the type of fruit...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at conveying by rollers or conveyor belts in the existing fruit and vegetable sorting technology, which is easy to cause skin damage to fruits and vegetables and affects the quality of fruits and vegetables. The single sorting equipment makes the identification device unable to accurately identify the grading information of fruits and vegetables, resulting in normal and accurate grading. However, due to the defects of wrong selection and missed selection, large manual labor is required for sorting, high production cost and low efficiency, a new free conveying fruit and vegetable sorting device and its sorting method are provided.
