Description

Technical Field

[0001] The present invention discloses a lossless sorting rod for a fruit and vegetable logistics sorting line and a fruit and vegetable logistics sorting line, which relates to a sorting rod installed on the fruit and vegetable logistics sorting line, and belongs to the field of intelligent logistics technology, and particularly relates to a sorting rod that drives an active gear plate to rotate through a third rotating motor, thereby driving a second telescopic rod to rotate, and the second telescopic rod drives an L-shaped connecting plate and a guide plate to rotate onto a main conveyor belt, intercepting fruits and vegetables with intact skins, and pulling fruits and vegetables with intact skins onto a secondary conveyor belt by inward contraction of the second telescopic rod, thereby reducing the risk of scratches or damage to the fruits and vegetables. Background Art

[0002] In the entire supply chain of fruits and vegetables from farmland to table, sorting is a key step to ensure the quality of fruits and vegetables. Through sorting, products that do not meet quality standards are removed, thereby ensuring that high-quality and healthy fruits and vegetables enter the market and meet the needs of consumers. Traditional fruit and vegetable sorting mainly relies on manual work, and the sorting efficiency is limited by the proficiency, physical fitness and emotional influence of the staff. It is also prone to problems such as misclassification and missed inspections of fruits and vegetables, which is time-consuming and labor-intensive. Against this background, intelligent sorting technology came into being. Most of the existing fruit sorting machines focus on the recognition and sorting of surface defects of fruits and vegetables, and identify and classify fruits and vegetables through image acquisition and processing systems; first, use a camera to capture images of fruits and vegetables, and then use image processing algorithms to extract the characteristics of fruits and vegetables. The sorting machine can accurately identify defects such as lesions, worm holes, and damage on the surface of fruits and vegetables by collecting characteristic information such as color, shape, and texture, and remove the fruits and vegetables with problems to ensure the external quality of fruits and vegetables. However, the existing fruit and vegetable sorting machines ignore the classification of fruit and vegetable weight, resulting in heavier fruits and vegetables being stacked on lighter fruits and vegetables, causing the lighter fruits and vegetables to be squeezed and damaged. In addition, heavier fruits and vegetables often mean more flesh and higher nutritional value, so the price will increase accordingly. If the sorting machine cannot accurately distinguish the weight of fruits and vegetables, it will limit the pricing strategy, making it difficult to reasonably price the fruits and vegetables according to their actual value, and failing to meet the individual needs of consumers, affecting consumer satisfaction, thereby causing waste of resources and increased costs.

[0003] Publication No. CN117259233A discloses a fruit sorting system and a sorting method, wherein the sorting system includes a conveyor belt for conveying fruits and a visual detection device, a frame is mounted on the conveyor belt, a mechanical arm for grabbing fruits is installed on the frame, and the visual detection device includes a first camera and a second camera, the first camera is located above the conveyor belt and is set downward, for obtaining a top view image of the fruit; the second camera is set on the side of the conveyor belt and is tilted upward toward the grabbing area of ​​the mechanical arm, for obtaining a top view image of the mechanical arm grabbing the fruit and leaving the conveyor belt; and also includes a sorting control system connected to the visual detection device and the mechanical arm, the sorting control system is used to control the mechanical arm to grab the fruit, and control the mechanical arm to classify and place the fruit according to the recognition result of the visual detection device. The above-mentioned sorting control system identifies whether there is a defect by taking a photo with the first camera, and then identifies whether there is a defect on the bottom surface of the fruit by taking a photo with the second camera, and performs calculations in combination with the above steps to control the mechanical arm to classify and place the fruit, thereby completing the sorting. However, the above-mentioned fruit sorting system ignores the weight of the fruit. Heavier fruits may be mistakenly placed above lighter fruits during the sorting process, causing the lighter fruits to be squeezed and damaged, affecting the quality of the fruits and increasing the difficulty and cost of subsequent processing. The actual value of the fruit cannot be determined by weighing, which may lead to underestimation or overestimation of the value, thus affecting the interests of producers and consumers.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Fruit Logistics Sorting Line", which uses a detection and sorting structure to sort out fruits with intact skins, and uses a weight sorting structure to classify fruits of different weights into multiple grades and sort them into different collection baskets. However, the device uses a cylinder to drive the push rod to extend and retract, and the push rod drives the buffer plate to push the fruits onto the secondary conveyor belt. When the push rod pushes the fruits, if the friction between the fruits and the buffer plate is insufficient, or the speed of the push rod is too fast, the fruits may slide or roll from the buffer plate, resulting in sorting errors, and may cause scratches, indentations and other damage to the skin of the fruits due to improper force, speed mismatch, etc., thereby affecting the appearance quality and market value of the fruits.

The data processor and the signal converter perform information exchange, When the fruit logistics sorting system is executed, the following steps are mainly implemented: Before sorting fruits and vegetables, the fruit logistics sorting system presets the grade of fruits and vegetables corresponding to each collection basket in advance. For example, collection basket No. 1 corresponds to apples with a net weight of less than 100 grams, collection basket No. 2 corresponds to apples with a net weight of more than 100 grams and less than 200 grams, collection basket No. 3 corresponds to apples with a net weight of more than 200 grams and less than 300 grams, and collection basket No. 4 corresponds to apples with a net weight of more than 300 grams.

According to the color histogram of normal fruits, a color threshold is set. If the color histogram of a certain area in the image differs from that of normal fruits by more than the threshold, there may be defects. Then, the image is preprocessed by grayscale conversion, denoising, contrast enhancement, etc., and a grayscale co-occurrence matrix is ​​constructed based on the grayscale image. The matrix reflects the texture information of the fruits in the image, such as roughness, smoothness, etc. According to the texture features of normal fruits, a texture threshold is set. If the texture features of a certain area in the image differ from those of normal fruits by more than the threshold, there may be defects. According to the results of the above defect detection, the fruit is classified as good or bad, and the information is output to the controller. When the fruit is bad, the fruit continues to be transported forward along the main conveyor belt to the end of the main conveyor belt and falls into the defective product collection box for subsequent processing. When the fruit is good, an execution instruction is sent to the control background, and the control background controls the cylinder to start, the cylinder drives the push rod to extend, and the push rod drives the buffer plate to push the fruit and vegetables onto the auxiliary conveyor belt, and the fruit and vegetables are transported along the auxiliary conveyor belt, pass the limit plate, and fall to the weight detector on the turntable. The weight detector weighs the fruit. The net weight of fruits and vegetables is detected and collected, and the collected weight data signal is sent to the signal converter. The signal converter converts the electrical signal of the received weight data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received weight data, compares the weight data with the preset grade of fruits and vegetables, and finds the collection basket corresponding to the fruits and vegetables. When the fruits and vegetables reach the corresponding collection basket, the first rotating motor drives the dial plate to rotate, and the fruits and vegetables on the weight detector are dialed into the corresponding collection basket, which effectively improves the efficiency and accuracy of sorting; Furthermore, an anti-skid pad is disposed on the buffer plate, the anti-skid pad is disposed on one side of the buffer plate, the anti-skid pad is made of rubber, and the edge of the anti-skid pad is connected to the edge of the buffer plate; Furthermore, the collection basket is built with a buffer pad, which is placed on the inner bottom surface of the collection basket. The buffer pad is made of rubber, and the edge of the buffer pad is connected to the edge of the inner bottom surface of the collection basket. Beneficial Effects

[0008] 1. The third rotary motor drives the second telescopic rod to rotate, and the L-shaped connecting plate and the guide plate are rotated to the main conveyor belt in a relatively gentle manner to intercept the fruits and avoid strong impact or vibration, which helps to protect the integrity and freshness of the fruits.

The controller can be implemented by one or at least two application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components for executing instructions of the data processing device. The data processor and the signal converter perform information exchange, When the fruit logistics sorting system is executed, the following steps are mainly implemented: Before sorting the fruits and vegetables, the fruit and vegetable logistics sorting system presets in advance the grade of the fruits and vegetables corresponding to each collection basket (3), for example, collection basket No. 1 (3) corresponds to apples with a net weight of less than 100 grams, collection basket No. 2 (3) corresponds to apples with a net weight of more than 100 grams and less than 200 grams, collection basket No. 3 (3) corresponds to apples with a net weight of more than 200 grams and less than 300 grams, and collection basket No. 4 (3) corresponds to apples with a net weight of more than 300 grams. In the process of sorting fruits and vegetables, the fruits and vegetables are transported to the main conveyor belt (13) at intervals. The controller controls the first drive motor (20) and the second drive motor (27) to start. The first drive motor (20) drives the first main roller to rotate. The first main roller drives the first slave roller to rotate, so that the fruits and vegetables are wrapped on the main conveyor belt (13) for transportation. The second drive motor (27) drives the second main roller to rotate. The second main roller drives the second slave roller to rotate, so that the secondary conveyor belt (10) can run smoothly. The detection probe (14) collects image data of the fruits and vegetables on the main conveyor belt (13), and sends the collected image data signal to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received image data. First, the target and background of the image are segmented, and the color features in the image are captured through the color histogram, and only normalized to reflect the color information of the fruits in the image. According to the color histogram of normal fruits, a color threshold is set. If the color histogram of a certain area in the image differs from that of normal fruits by more than the threshold, there may be defects. Then, the image is preprocessed by grayscale conversion, denoising, contrast enhancement, etc., and a grayscale co-occurrence matrix is ​​constructed based on the grayscale image. The matrix reflects the texture information of the fruits in the image, such as roughness, smoothness, etc. According to the texture features of normal fruits, a texture threshold is set. If the texture features of a certain area in the image differ from those of normal fruits by more than the threshold, there may be defects. According to the result of the defect detection, the fruit is classified as good or bad, and the information is output to the controller. When the fruit is bad, the fruit is continuously conveyed forward along the main conveyor belt (13) to the end of the main conveyor belt (13) and falls into a defective product collection box for subsequent processing. When the fruit is good, an execution instruction is sent to the control background, and the control background controls the cylinder (16) to start, the cylinder (16) drives the push rod (23) to extend, and the push rod (23) drives the buffer plate (24) to push the fruit and vegetable onto the auxiliary conveyor belt (10), and the fruit and vegetable are conveyed along the auxiliary conveyor belt, pass through the limit plate (6), and fall onto the weight detector (41) on the turntable (30). The weight detector (41) detects and collects the net weight of the fruits and vegetables, and sends the collected weight data signal to the signal converter. The signal converter converts the electrical signal of the received weight data signal into a digital signal and sends it to the data processor. The data processor processes the received digital signal of the weight data, compares the weight data with the preset grade of the fruits and vegetables, and finds the collection basket (3) corresponding to the fruits and vegetables. When the fruits and vegetables reach the corresponding collection basket (3), the first rotating motor (32) drives the shifting plate (31) to rotate, and shifts the fruits and vegetables on the weight detector (41) into the corresponding collection basket (3), thereby effectively improving the efficiency and accuracy of sorting.

The one-to-one correspondence between the weight detectors (41) and the separation areas enables rapid classification of the items according to their weight data and preset weight grade standards, thereby improving the efficiency of the entire processing flow and reducing the impact of human factors on the classification results. The length of the paddle plate (31) is less than the length of the partition plate (5), and the height of the paddle plate (31) is less than the height of the partition plate (5), so that the paddle plate (31) can accurately locate the fruits and vegetables when rotating, and accurately paddle them into the collection basket (3), and it helps to avoid excessive friction with the partition plate (5) during the paddle process, thereby maintaining the smoothness and accuracy of the paddle; One end of the arc-shaped baffle plate (4) is connected to one-half of the long side of the shifting plate (31), and the other end of the arc-shaped baffle plate (4) is close to the weight detector (41), which can reduce the impact force and make the fruits and vegetables slide more stably, thereby reducing the risk of rolling into the wrong partition; The inner side of the collection basket (3) is provided with a bubble column cushion (46), and the collection basket (3) is filled with clean water.

The spring (35) absorbs and stores impact energy through its elastic deformation, and the damper (34) reduces the vibration amplitude by consuming energy. This can more effectively reduce the impact and vibration of fruits and vegetables during the transportation process. By changing parameters such as the length of the telescopic rod (38), the stiffness of the spring (35) and the damping characteristics of the damper (34), it is possible to meet the shock absorption requirements of fruits and vegetables of different weights, shapes and sizes.
