[0053] Please refer to Figures 1 to 8 The present embodiment provides a fruit and vegetable detection pipeline, comprising:

[0054] A conveying assembly 10 is used to convey fruits and vegetables;

[0055] A single fruit conveying unit 20 is connected with the output end of the conveying assembly 10, and the single fruit conveying unit 20 is used to sequentially convey the fruits and vegetables conveyed and output by the conveying assembly 10;

[0056] A weighing unit 30 is placed on the single fruit conveying unit 20, and the weighing unit 30 is used to weigh each fruit and vegetable and obtain a preset single fruit weight;

[0057] A first sorting unit 40 is provided, and a plurality of first sorting units 40 are placed on the side of the single fruit conveying unit 20. The first sorting unit 40 is used to receive the fruits and vegetables falling from the single fruit conveying unit 20. The plurality of first sorting units 40 correspond to a plurality of preset single fruit weights and a preset single portion weight, respectively. When the weight in the first sorting unit 40 reaches the preset single portion weight, the single fruit conveying unit 20 will stop conveying fruits and vegetables to the corresponding first sorting unit 40;

[0058] A link conveying unit 50 is connected with the output end of the first sorting unit 40 and the link conveying unit 50. The link conveying unit 50 is used to receive and convey the fruits and vegetables on the first sorting unit 40. When the weight in the first sorting unit 40 reaches the preset single portion weight, the link conveying unit 50 conveys and receives the fruits and vegetables;

[0059] A grid conveying unit 60 is connected with the link conveying unit 50, and the grid conveying unit 60 is used to receive the fruits and vegetables conveyed by the link conveying unit 50;

[0060] A packing unit 70 is connected with the grid conveying unit 60, and the packing unit 70 is used to pack fruits and vegetables.

[0061] The conveying assembly 10 is used for conveying and cleaning fruits and vegetables. The input end of the single fruit conveying unit 20 is connected to the output end of the conveying assembly 10. Specifically, a trapezoidal guide member is arranged at the connection between the two, the input end of the guide member is matched with the output end of the conveying assembly 10 to simultaneously receive multiple fruits and vegetables, and the output end of the guide member is matched with the input end of the single fruit conveying unit 20 to output single fruits and vegetables to the single fruit conveying unit 20. Further, the guide member is arranged around the funnel.

[0062] The single fruit conveying unit 20 is in a "v" shape in cross section, and the single fruit conveying unit 20 supports the bottom of the fruits and vegetables. Specifically,

[0063] Firstly, the single fruit conveying unit 20 includes two symmetrically arranged first conveying belts, which are arranged obliquely to clamp the fruits and vegetables. The running rates of the two first conveying belts are equal to avoid abrasion or rolling of the fruits and vegetables.

[0064] Secondly, the single fruit conveying unit 20 includes two symmetrically arranged limiting plates and a second conveying belt, the limiting plates are arranged obliquely, the second conveying belt is arranged between the limiting plates, and the fruits and vegetables are arranged on the second conveying belt. The limiting plates are used to prevent the fruits and vegetables from falling, and the second conveying belt is used to move the fruits and vegetables.

[0065] Of course, in some embodiments, the single fruit conveying unit 20 includes a guide roller set and a chain plate, a plurality of guide roller sets are arranged along the chain plate array, each guide roller set includes two symmetrically arranged rollers, the chain plate is arranged between the two rollers, and the surface of the roller is inclined to the chain plate. The fruits and vegetables are stably arranged on the chain plate by the guide roller set.

[0066] The weighing unit 30 is arranged on the single fruit conveying unit 20, and the weighing unit 30 is used to weigh each passing fruit and vegetable. Specifically, the weighing unit 30 is arranged below the single fruit conveying unit 20, when the fruits and vegetables are moved to above the weighing unit 30 under the drive of the single fruit conveying unit 20, the weighing unit 30 weighs the single fruit and vegetable and uploads the record.

[0067] The weighing unit 30 is an electronic weighing module, and any fruit and vegetable passing through the electronic weighing module will exert pressure on the electronic weighing module, i.e. the weight of the fruit and vegetable. At this time, the electronic weighing module will record this weight or send the value to the processor.

[0068] The first sorting unit 40 is arranged along the direction of the single fruit conveying unit 20, and the first sorting unit 40 is arranged on one side of the single fruit conveying unit 20.

[0069] Each first sorting unit 40 corresponds to a preset single fruit weight and a preset single serving weight; the preset single fruit weight is the weight of a single fruit, and the preset single serving weight is the weight of a plurality of fruits and vegetables packed together.

[0070] Specifically, taking one first sorting unit 40 as an example, the preset single fruit weight corresponding to the first sorting unit 40 is 90-130g, and the preset single serving weight is 500-600g. When the weighing unit 30 detects that the single fruit weight reaches 90-130g, the single fruit is controlled to fall into the corresponding first sorting unit 40; when the weight in the first sorting unit 40 reaches 500-600g, the single fruit conveying unit 20 will stop transporting fruits and vegetables to the corresponding first sorting unit 40.

[0071] It should be further noted that the picking unit is also included, and the picking unit is a plurality of units, which one-to-one corresponds to a plurality of first sorting units 40. The picking unit is placed on the side of the single fruit conveying unit 20 away from the first sorting unit 40 to pick up single fruits; specifically, when the fruits and vegetables are weighed and the single fruit weight is obtained, the picking unit picks up the fruits and vegetables when the single fruit moves to the corresponding first sorting unit 40.

[0072] Further, after obtaining the single fruit weight, the single fruit can be accurately dropped into the corresponding first sorting unit 40 according to the moving speed or according to the detected number of single fruits; specifically, after obtaining the single fruit weight, the single fruit is marked, and the moving time of the single fruit to the side of the corresponding first sorting unit 40 is calculated according to the moving speed of the single fruit conveying unit 20, and the picking unit picks up the single fruit.

[0073] Please refer to Figures 6 to 7 , the first sorting unit 40 includes an upper cover body 41, a lower cover body 42, and a containing frame 43, the containing frame 43 is provided with an upper opening and a lower opening, the upper cover body 41 is covered on the upper opening, and the lower cover body 42 is covered on the lower opening; the fruits and vegetables enter the containing frame 43 from the upper opening, and the fruits and vegetables move out of the containing frame 43 from the lower opening.

[0074] In some embodiments, the upper cover body 41 is placed in the containing cavity and divides the containing cavity into a first cavity and a second cavity. The first cavity is close to the single fruit conveying unit 20; in actual use, when the lower cover body 42 is opened, the upper cover body 41 is closed, at this time the first cavity can immediately receive fruits and vegetables to improve the sorting efficiency of the first sorting unit 40.

[0075] The connection conveying unit 50 receives the fruits and vegetables output from the lower opening. When the total weight of the fruits and vegetables in the first sorting unit 40 reaches the preset single serving weight, the lower opening opens and the fruits and vegetables fall into the connection conveying unit 50. At the same time, the connection conveying unit 50 starts and moves the fruits and vegetables to the grid conveying unit 60 mentioned below. Meanwhile, the upper cover body 41 closes the upper opening to prevent other fruits and vegetables from entering the containing frame 43.

[0076] It should be noted that the starting condition of the lower cover body 42 and the connection conveying unit 50 is that the total weight of the fruits and vegetables in the first sorting unit 40 reaches the preset single serving weight.

[0077] The grid conveying unit 60 is connected with the connection conveying unit 50, and the grid conveying unit 60 is used to receive the fruits and vegetables conveyed by the connection conveying unit 50. Specifically, when the connection conveying unit 50 moves the single serving of fruits and vegetables to the grid conveying unit 60, the grid conveying unit 60 has a plurality of grids (i.e., the separation frame 61 mentioned below), and each grid contains a serving of fruits and vegetables.

[0078] Similarly, when the total weight of the fruits and vegetables in the first sorting unit 40 reaches the preset single serving weight, the grid conveying unit 60 starts after a preset time to convey the classified serving of fruits and vegetables to the packaging unit 70. Then the packaging unit 70 packs the fruits and vegetables.

[0079] Unlike the prior art, in the above technical solution, the single fruit conveying unit 20 is connected with the output end of the conveying assembly 10, and is used to separate and transport each of the plurality of fruits and vegetables output by the conveying assembly 10. The V-shaped single fruit conveying unit 20 ensures the stable conveying of each fruit and vegetable, provides an accurate control basis for subsequent weighing and sorting steps, and improves the accuracy and efficiency of sorting. The weighing unit 30 is used to weigh each passing fruit and vegetable and record the weight of each fruit and vegetable. The weighing unit 30 can accurately obtain the weight information of each fruit and vegetable, provide data support for sorting single fruits, and ensure the quality control and accuracy of the product. When the weighing unit 30 detects a fruit and vegetable that meets the preset single fruit weight, the fruit and vegetable is conveyed to the corresponding first sorting unit 40. The first sorting unit 40 classifies and collects the fruits and vegetables according to their weights, ensures that fruits and vegetables of the same weight are classified together, provides convenience for subsequent packaging, and also improves the quality and consistency of the product. In turn, it improves the efficiency of the packaging and detection of the assembly line.

[0080] According to some embodiments of the present application, with reference to Figures 1 to 3 Each of the connection conveying units 50 receives two fruits and vegetables conveyed by the first sorting unit 40;

[0081] Each of the grid conveying units 60 receives the fruits and vegetables conveyed by two of the connection conveying units 50.

[0082] In the present embodiment, four of the first sorting units 40 are taken as an example for illustration, and the four first sorting units 40 are arranged side by side. Two of the connection conveying units 50 are arranged opposite to each other at the output ends. One of the grid conveying units 60 is arranged between the two connection conveying units 50.

[0083] The four first sorting units 40 arranged side by side are labeled as CHU02, CHU03, CHU04 and CHU05 from left to right. The two connection conveying units 50 are labeled as DB1-01 and DB1-02 from left to right. The connection conveying unit 50 labeled as DB1-01 receives the first sorting units 40 labeled as CHU02 and CHU03. The connection conveying unit 50 labeled as DB1-02 receives the first sorting units 40 labeled as CHU04 and CHU05.

[0084] In actual operation, when the weight of the fruits and vegetables in the first sorting unit 40 reaches the preset single serving weight, the first sorting unit 40 stops conveying the fruits and vegetables to the corresponding single fruit conveying unit 20, and triggers the connection conveying unit 50 to start working. At this time, the connection conveying unit 50 receives the fruits and vegetables from the first sorting unit 40 and conveys them to the next link.

[0085] Since each of the connection conveying units 50 can receive the fruits and vegetables from two first sorting units 40 that release the fruits and vegetables alternately, parallel processing and conveying of the fruits and vegetables can be achieved. This improves the processing capacity and efficiency of the flow line.

[0086] Similarly, the two connection conveying units 50 alternately convey the ingredients of fruits and vegetables to the grid conveying unit 60. The grid conveying unit 60 receives the classified ingredients of fruits and vegetables and conveys them to the packing unit 70 for packing.

[0087] In actual use, at 0s, the first sorting unit 40 numbered CHU02 is full, triggering the lower cover body 42 of the first sorting unit 40 numbered CHU02 to open and release the goods, while triggering the connection conveying unit 50 numbered DB1-01 to run, setting the release time of the first sorting unit 40 numbered CHU02 to 0.5s, and setting the running time of the connection conveying unit 50 numbered DB1-01 to 1.5s, which means that the goods on the first sorting unit 40 numbered CHU02 need to be conveyed to the compartment conveying unit 60 (the length of the connection conveying unit 50 is 1m, and the speed is 1m / s) within 1s. At 1.5s, the compartment conveying unit 60 runs and conveys forward for 0.5s (conveying the next compartment to the waiting position, the length of the compartment is 0.3m, and the speed of the compartment conveying unit 60 is 0.6m / s). At 2s, the first sorting unit 40 numbered CHU04 is full, triggering the lower cover body 42 of the first sorting unit 40 numbered CHU04 to open and release the goods, while triggering the connection conveying unit 50 numbered DB1-02 to run, setting the release time of the first sorting unit 40 numbered CHU04 to 0.5s, and setting the running time of the connection conveying unit 50 numbered DB1-02 to 1.5s, which means that the goods on the first sorting unit 40 numbered CHU04 need to be conveyed to the compartment conveying unit 60 (the length of the connection conveying unit 50 is 1m, and the speed is 1m / s) within 1s. At 3.5s, the compartment conveying unit 60 runs and conveys forward for 0.5s (conveying the next compartment to the waiting position, the length of the compartment is 0.3m, and the speed of the compartment conveying unit 60 is 0.6m / s). At 4s, the first sorting unit 40 numbered CHU03 is full, and so on.

[0088] According to some embodiments of the present application, with reference to Figure 3 , the compartment conveying unit 60 comprises a partition frame 61 and a driving member 62, the driving member 62 is in transmission connection with a plurality of partition frames 61, and the partition frame 61 is used to receive and transport the fruits and vegetables output by the connection conveying unit 50;

[0089] When one connection conveying unit 50 transports fruits and vegetables, one partition frame 61 is placed on one side of the output end of the connection conveying unit 50 conveying the fruits and vegetables to receive the fruits and vegetables.

[0090] The driving member 62 comprises a roller and a belt, the roller is two, the two rollers are arranged at intervals, and the belt is sleeved on the two rollers; a plurality of partition frames 61 are arranged in an array on the belt, and each partition frame 61 receives a portion of fruits and vegetables.

[0091] According to some embodiments of the present application, with reference to Figure 1 , the conveying assembly 10 comprises:

[0092] a plurality of inspection tables 11;

[0093] a first conveying unit 12, the plurality of inspection tables 11 are placed on both sides of the first conveying unit 12, and the first conveying unit 12 is used to receive the fruits and vegetables after inspection;

[0094] a second conveying unit 13, the second conveying unit 13 is placed on one side of the output end of the first conveying unit 12, and the second conveying unit 13 is used to receive the fruits and vegetables on the first conveying unit 12.

[0095] The second conveying unit 13 is inclined, and the second conveying unit 13 is used to filter the impurities mixed in the fruits and vegetables;

[0096] The second conveying unit 13 includes a plurality of rollers 131, and the plurality of rollers 131 are arranged in an inclined array along the conveying direction. A plurality of inspection tables 11 are placed at the beginning of the assembly line for preliminary quality inspection of fruits and vegetables entering the assembly line. The quality inspectors can select, classify and mark the fruits and vegetables on these inspection tables 11 to ensure that only fruits and vegetables meeting the quality standards can enter the subsequent conveying and processing links.

[0097] The first conveying unit 12 is used to receive the fruits and vegetables after inspection. This conveying unit can adopt a belt conveyor, a roller conveyor or other suitable conveying equipment to stably convey the fruits and vegetables to the next link.

[0098] The second conveying unit 13 is located on one side of the output end of the first conveying unit 12, and is used to further receive and convey the fruits and vegetables. Unlike the first conveying unit 12, the second conveying unit 13 is designed to be inclined, so that the gravity of the fruits and vegetables themselves can be used to filter out impurities such as leaves, soil, etc. during conveying.

[0099] The specific structure of the second conveying unit 13 includes a plurality of rollers 131, and the plurality of rollers 131 are arranged in an array along the conveying direction. The spacing of the rollers 131 can be adjusted according to the type and size of the fruits and vegetables to ensure the best conveying and impurity filtering effect, i.e. impurities falling from the gap between the rollers 131.

[0100] In actual use, the fruits and vegetables are first placed on the inspection tables 11 and subjected to preliminary quality inspection by the quality inspectors. After selection, classification and marking, the qualified fruits and vegetables are placed on the first conveying unit 12. The first conveying unit 12 stably conveys the fruits and vegetables to the second conveying unit 13. In this process, the fruits and vegetables are smoothly conveyed to the next link, while avoiding damage and confusion during conveying.

[0101] When the fruits and vegetables enter the second conveying unit 13, due to the inclined arrangement of the second conveying unit 13, the fruits and vegetables will slide down along the inclined surface of the rollers 131 under the action of gravity. In this process, impurities such as leaves and soil mixed in the fruits and vegetables fall from the gap between the rollers 131 and remain at the bottom of the second conveying unit 13. Further, in some embodiments, the surface of the rollers 131 is a concave-convex surface.

[0102] The conveying assembly 10 can more effectively convey and process fruits and vegetables, improving production efficiency and product quality.

[0103] According to some embodiments of the present application, with reference to Figure 2 , further comprising:

[0104] The buffer unit 80 is connected with the packaging unit 70, and the buffer unit 80 is used to receive the packaged fruits and vegetables.

[0105] The specific implementation of the buffer unit 80 can be one or more storage areas, which can be fixed shelves, mobile pallet cars, or automated warehouse systems. The size and number of the buffer unit 80 can be flexibly configured according to the types and quantities of fruits and vegetables and the processing capacity of the assembly line.

[0106] Specifically, the packaged fruits and vegetables need to be manually transferred to the finished product area. In order to avoid the accumulation of fruits and vegetables after packaging, the fruits and vegetables that have not been transferred in time will be placed in the buffer unit 80; preferably, the buffer unit 80 is a slowly rotating disc.

[0107] In actual operation, first, the fruits and vegetables pass through the conveying assembly 10, the single fruit conveying unit 20, the weighing unit 30, the first sorting unit 40, the connecting conveying unit 50, and the compartment conveying unit 60 on the assembly line, and finally reach the packaging unit 70. In the packaging unit 70, the fruits and vegetables are packaged according to the predetermined specifications and quantities. The packaged fruits and vegetables are conveyed to the buffer unit 80. In this process, the workers or automated systems of the buffer unit 80 will place the fruits and vegetables in the appropriate storage area according to the types, quantities, and storage requirements of the fruits and vegetables.

[0108] According to some embodiments of the present application, with reference to Figures 4 to 5 , further comprising: a visual detection unit 90, the visual detection unit 90 is built-in detection channel for the single fruit conveying unit 20 to pass through, the single fruit conveying unit 20 is placed in the detection channel, and the visual detection unit 90 is used to detect the fruits and vegetables on the single fruit conveying unit 20.

[0109] The detection channel built-in the visual detection unit 90, and the single fruit conveying unit 20 is completely placed in this detection channel.

[0110] The core components of the visual detection unit 90 typically include high-precision cameras, image processors, and corresponding control software. The cameras are responsible for capturing images of each fruit or vegetable on the single-fruit conveying unit 20, while the image processors are responsible for rapid and accurate analysis and processing of these images. The control software is responsible for coordinating the entire visual detection process to ensure accuracy and efficiency of detection.

[0111] The design of the detection channel takes into full consideration the characteristics of fruits and vegetables and the detection requirements, with appropriate width and height to ensure that fruits and vegetables can pass through smoothly without any obstruction. At the same time, the inside of the detection channel is equipped with appropriate lighting equipment to ensure that the cameras can capture clear and bright images.

[0112] In operation, first, fruits and vegetables are conveyed onto the single-fruit conveying unit 20 by the conveying assembly 10. Under the drive of the single-fruit conveying unit 20, the fruits and vegetables pass through the detection channel of the visual detection unit 90 one by one at a certain speed and spacing. When the fruits and vegetables enter the detection channel, the cameras immediately capture their images. Due to the high precision and high resolution of the cameras, they can capture the subtle features and defects on the surface of the fruits and vegetables. The captured images are transmitted to the image processor for further analysis and processing. The image processor uses advanced algorithms and techniques to identify, classify, and judge the images. It can identify the type, size, shape, and surface flaws and defects of the fruits and vegetables. After analysis and processing, the image processor feeds back the results to the control system of the assembly line. The control system performs further sorting, processing, or marking operations on the fruits and vegetables based on these information. If the visual detection unit 90 finds that the fruits and vegetables have flaws or defects, the control system will immediately trigger the corresponding sorting mechanism (such as the second sorting unit 100) to remove them from the assembly line. At the same time, for qualified fruits and vegetables, subsequent weighing, sorting, interfacing conveying, bin conveying, and packaging processes are carried out along the assembly line.

[0113] The addition of the visual detection unit 90 enables comprehensive, rapid, and accurate detection of fruits and vegetables. This not only improves the quality and safety of fruits and vegetables, but also reduces manual intervention and production costs. At the same time, this design also makes the assembly line more intelligent and automated, and can adapt to the detection needs of different types and specifications of fruits and vegetables.

[0114] According to some embodiments of the present application, with reference to Figure 5 , further comprising: a second sorting unit 100; the second sorting unit 100 is placed on the side of the single-fruit conveying unit 20, and the second sorting unit 100 is used to receive the damaged fruits and vegetables falling from the single-fruit conveying unit 20; wherein when the visual detection unit 90 detects damaged fruits and vegetables, the single-fruit conveying unit 20 will transport the damaged fruits and vegetables to the second sorting unit 100.

[0115] The second sorting unit 100 is used to receive and process the damaged fruits and vegetables that fall off the single fruit conveying unit 20.

[0116] The second sorting unit 100 is a sorting mechanism with a receiving port. The receiving port is designed to correspond to the output end of the single fruit conveying unit 20, so as to accurately receive the damaged fruits and vegetables that fall off the single fruit conveying unit 20.

[0117] In order to ensure that the second sorting unit 100 can accurately receive and process the damaged fruits and vegetables, the control system of the flow line needs to closely cooperate with the visual detection unit 90. When the visual detection unit 90 detects damaged fruits and vegetables, it will immediately send a signal to the control system. After receiving this signal, the control system will trigger the single fruit conveying unit 20 to convey the damaged fruits and vegetables to the receiving port of the second sorting unit 100.

[0118] Specifically, the fruits and vegetables pass through the single fruit conveying unit 20. Under the drive of the single fruit conveying unit 20, the fruits and vegetables pass through the flow line in sequence. In this process, the visual detection unit 90 will conduct detailed detection on each fruit and vegetable to identify whether there is damage or defect. When the visual detection unit 90 detects damaged fruits and vegetables, it will immediately send a signal to the control system of the flow line. This signal contains information such as the position, type and damage degree of the damaged fruits and vegetables.

[0119] After receiving the signal from the visual detection unit 90, the control system will immediately regulate the single fruit conveying unit 20. Specifically, the control system will control the conveying speed, direction and stopping position of the single fruit conveying unit 20, etc. to ensure that the damaged fruits and vegetables can be accurately conveyed to the receiving port of the second sorting unit 100.

[0120] According to some embodiments of the present application, with reference to Figure 3 Further comprising: a backflow unit 110;

[0121] The input end of the backflow unit 110 is connected with the output end of the single fruit conveying unit 20, and the output end of the backflow unit 110 is connected with the input end of the conveying assembly 10. The backflow unit 110 is used to receive the unsorted fruits and vegetables.

[0122] The backflow unit 110 is used to process those fruits and vegetables that have not been successfully sorted by the first sorting unit 40 and the second sorting unit 100, so as to ensure that they can re-enter the flow line for reprocessing or sorting.

[0123] The input end of the backflow unit 110 is connected with the output end of the single fruit conveying unit 20, used for receiving those fruits and vegetables which are not accepted by the first sorting unit 40 and the second sorting unit 100. The output end is connected with the input end of the conveying assembly 10, ensuring that these fruits and vegetables can re-enter the assembly line.

[0124] The backflow unit 110 is equipped with a conveying belt or rollers inside, to ensure that the fruits and vegetables can be smoothly and quickly conveyed from the input end to the output end.

[0125] In actual use, first, the fruits and vegetables are conveyed to the single fruit conveying unit 20 by the conveying assembly 10. Under the drive of the single fruit conveying unit 20, the fruits and vegetables are weighed in turn by the weighing unit 30, and are conveyed to the corresponding first sorting unit 40 for sorting according to the preset single fruit weight. During the sorting process, if a fruit and vegetable passes by when the first sorting unit 40 is closed, it will not be pushed in, it will continue to move forward along the single fruit conveying unit 20, and finally be conveyed to the input end of the backflow unit 110.

[0126] The fruits and vegetables entering the backflow unit 110 will be conveyed to the output end and re-enter the conveying assembly 10. At this time, they will pass through the entire assembly line again, and go through the weighing, sorting and other processing procedures.

[0127] By adding the backflow unit 110, automatic backflow processing of unsorted fruits and vegetables is realized. This not only can improve the processing efficiency and accuracy of the assembly line, but also can reduce manual intervention and reduce production cost.
