Description

Technical Field

[0001] The present invention discloses a dynamic flow guiding and conveying structure for a fruit and vegetable logistics sorting line and a fruit and vegetable logistics sorting line, which relate to a flow guiding and conveying structure installed on the fruit and vegetable logistics sorting line, and belong to the field of intelligent logistics technology, and particularly to a flow guiding and conveying structure in which an L-shaped connecting plate is driven to rotate by a fourth rotating motor to block fruits and vegetables with no surface damage, and prevent the fruits and vegetables from sliding away due to gravity or inertia during transportation, thereby ensuring stable transmission of the fruits and vegetables, and a third rotating motor is used to drive an active rotating shaft to rotate, thereby driving a second rotating belt, a driven rotating shaft and a first transmission belt to rotate, so that the fruits and vegetables with no damage are conveyed to a secondary conveyor belt along a rotating roller in the direction of a diversion trough, thereby reducing the risk of the fruits and vegetables being scratched or damaged and improving the accuracy of sorting. 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 breakage 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. Summary of the invention

[0005] In order to improve the above situation, the present invention provides a dynamic diversion and transmission structure of a fruit and vegetable logistics sorting line and a fruit and vegetable logistics sorting line. A fourth rotating motor is used to drive an L-shaped connecting plate to rotate, so as to block fruits and vegetables with no damage on the surface and prevent the fruits and vegetables from sliding away due to gravity or inertia during transportation, thereby ensuring stable transmission of the fruits and vegetables. The third rotating motor is used to drive the active rotating shaft to rotate, thereby driving the second rotating belt, the driven rotating shaft and the first transmission belt to rotate, so that the undamaged fruits and vegetables are transported to the auxiliary conveyor belt along the rotating roller in the direction of the diverter trough, thereby reducing the risk of scratches or damage to the fruits and vegetables.

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.

A color threshold is set based on the color histogram of normal fruits. 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. The image is then preprocessed by graying, denoising, and contrast enhancement, 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 and smoothness. A texture threshold is set based on the texture features of normal fruits. 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

The control backend controls the third rotating motor (53) to start, the third rotating motor (53) drives the driving shaft (52) to rotate, the driving shaft (52) drives the second rotating belt (51) to rotate, the second rotating belt (51) drives one of the driven shafts (49) close to the L-shaped connecting plate (55) to rotate, one of the driven shafts (49) drives the first rotating belt to rotate, the first rotating belt drives the remaining driven shafts (49) to rotate, the good quality fruits are transported along the main conveyor belt (13) to one side of the fixed frame (47), and then transported along the rotating roller (50) to the auxiliary conveyor belt (10) for subsequent processing, which can prevent the fruits from sliding away due to gravity or inertia during the transportation process, thereby ensuring the stable transmission of the fruits, avoiding direct contact and friction between the fruits and the conveyor belt, reducing the risk of the fruits being scratched or damaged, and ensuring the quality and appearance of the fruits.

[0013] Example 2 The difference between this embodiment and embodiment 1 is that: the height of the fixed frame (47) is less than the height of the L-shaped connecting plate (55), the top of the fixed frame (47) is flush with the top of the L-shaped connecting plate (55), the top of the brush (58) is connected to the bottom of the fixed frame (47), the bottom of the brush (58) hangs down to the main conveyor belt (13), there are multiple brushes (58), the multiple brushes (58) include hard brushes (58) and soft brushes (58), the hard brushes (58) and the soft brushes (58) are staggered along the bottom of the fixed frame (47).

The oblique bristles can more effectively remove stains on the conveyor belt, and its curled shape can increase the contact area with the conveyor belt, thereby improving the cleaning efficiency.

[0014] Example 3 The difference between this embodiment and the first embodiment is that: the shock absorbing sleeve (59) is sleeved on the rotating roller (50), the shock absorbing sleeve (59) is made of food-grade silicone material, and has an anti-skid texture on its surface. The height of the shock absorbing sleeve (59) is equal to the height of the rotating roller (50). When in use, the direct collision and impact of the fruit with the rotating roller (50) during the transmission process can be significantly reduced, thereby reducing the breakage rate of the fruit. The food-grade material ensures that no harmful substances are released when the shock absorbing sleeve (59) contacts the fruit, thereby ensuring the edible safety of the fruit. The anti-skid texture design increases the friction between the shock absorbing sleeve (59) and the fruit, thereby facilitating a more stable transmission of the fruit on the rotating roller (50), reducing sliding and rolling, and further reducing the risk of breakage. The design in which one end of the reinforcing rib is connected to the bottom of the receiving plate (54) and the other end of the reinforcing rib is connected to the right angle of the middle part of the L-shaped connecting plate (55) can effectively improve the connection strength between the receiving plate (54) and the L-shaped connecting plate (55), thereby enhancing the stability of the entire structure, enabling the entire structure to withstand greater loads and impact forces, and improving its durability and reliability; The distance between adjacent driven rotating shafts (49) is slightly larger than the diameter of the rotating roller (50), and the distance between two adjacent rotating rollers (50) is less than 5 mm, which can ensure that the fruits move stably along the rotating rollers (50) during the transmission process, thereby reducing the sliding or rolling instability of the fruits during the transmission process; The design of the side of the rotating roller (50) protruding from the fixed frame (47) can prevent the fruit from contacting the edge of the fixed frame (47), thereby reducing damage caused by collision or squeezing, and helps to support the fruit and prevent it from sliding due to speed changes during the transfer process; A buffer layer is disposed on the side of the rotating roller (50). The buffer is a double-layer structure, and is designed to be a sponge layer and a fiber layer from the inside to the outside. It can absorb the impact force generated by speed changes or contact of the fruits during the transmission process, reduce damage to the fruits, reduce scratches or crushing caused by contact with hard objects, and protect the fruit skin from damage. At the same time, the fiber layer can provide additional friction to prevent the fruits from sliding or turning over during the transmission process, thereby ensuring the stability of the transmission; The bottom surface of the fixed frame (47) is in contact with the main conveyor belt (13). The smooth design of the bottom surface of the fixed frame (47) can significantly reduce the friction between the fixed frame (47) and the main conveyor belt (13), thereby extending the service life of the conveyor belt and the fixed frame (47), significantly saving energy, and improving the operating efficiency of the sorting line; The L-shaped connecting plate (55), the fixing frame (47) and the fourth rotating motor (57) are designed to cooperate with each other, so that the fixing frame (47) can quickly adjust its position, thereby achieving efficient transportation and sorting of fruits and vegetables, reducing the risk of fruits and vegetables sliding away due to gravity or inertia, and thus reducing the possibility of fruits and vegetables being damaged; The fourth rotating motor (57) drives the L-shaped connecting plate (55) to rotate, thereby blocking fruits with intact surfaces and preventing the fruits from sliding away due to gravity or inertia during transportation, thereby ensuring stable transportation of the fruits. The third rotating motor (53) drives the active rotating shaft (52) to rotate, thereby driving the second rotating belt (51), the driven rotating shaft (49) and the first transmission belt (48) to rotate, so that the intact fruits are transported to the auxiliary conveyor belt (10) along the rotating roller (50) in the direction of the diverter trough (25), thereby reducing the risk of the fruits being scratched or damaged.

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 image is segmented from the target and background, and the color features in the image are captured through the color histogram, which is then normalized to reflect the color information of the fruits in the image. A color threshold is set based on the color histogram of normal fruits. 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. The image is then preprocessed by graying, denoising, and contrast enhancement, 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 and smoothness. A texture threshold is set based on the texture features of normal fruits. 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 above-mentioned 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 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 (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 the fruits and vegetables on the weight detector (41) are shifted 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 according to the weight data and the preset weight grade standard, thereby improving the efficiency of the entire processing flow and reducing the influence 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 volume of the clean water is designed to be half of the volume of the collection basket (3). The bubble column cushion (46) can effectively absorb and buffer external impact force, and the clean water can provide a certain buoyancy, thereby reducing direct contact between fruits and vegetables, and further reducing the risk of extrusion damage; The damper (34), the telescopic rod (38) and the spring (35) are designed to cooperate with each other. 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. The purpose is to be able to continuously and quickly transport fruits and vegetables through the main transport structure and the auxiliary transport structure, to sort out fruits and vegetables with intact skins through the detection and sorting structure, and to classify fruits and vegetables of different weights into multiple grades through the weight sorting structure and sort them into different collection baskets (3).

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. In the process of sorting fruits and vegetables, the fruits and vegetables are transported to the main conveyor belt at intervals, the controller controls the first drive motor and the second drive motor to start, the first drive motor drives the first main roller to rotate, and the first main roller drives the first main roller to rotate. The first slave roller is driven to rotate, so that the fruits and vegetables are wrapped on the main conveyor belt for transportation. The second drive motor drives the second main roller to rotate, and the second main roller drives the second slave roller to rotate, so that the secondary conveyor belt can run smoothly. The detection probe collects image data of the fruits and vegetables on the main conveyor belt, 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, firstly segments the image from the target and background, captures the color features in the image through the color histogram, and only normalizes it to reflect the color information of the fruits in the image. According to the color histogram of normal fruits Figure, set the color threshold, if the color histogram of a certain area in the image and the color histogram of normal fruits differ by more than the threshold, there may be defects, then the image is preprocessed by grayscale, 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 characteristics of normal fruits, a texture threshold is set. If the texture characteristics of a certain area in the image and the texture characteristics of normal fruits differ 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 defective, and the information is output to the controller. When the fruit is defective, the fruit continues to be transported forward along the main conveyor belt to the end of the main conveyor belt and falls to the defective part. The fruits and vegetables are then put into the collection box for subsequent processing. When the fruits and vegetables are good products, an execution instruction is sent to the control background. The control background controls the cylinder to start, and the cylinder drives the push rod to extend. The push rod drives the buffer plate to push the fruits and vegetables onto the auxiliary conveyor belt, and the fruits and vegetables are transported along the auxiliary conveyor belt. After passing the limit plate, they fall onto the weight detector on the turntable. The weight detector 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 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 rotary motor drives the pick plate to rotate, and the fruits and vegetables on the weight detector are picked up and put into the corresponding collection basket, which effectively improves the efficiency and accuracy of sorting.
