[0059] A connecting and conveying unit 50, wherein the connecting and conveying unit 50 is connected to the output end of the first sorting unit 40 and the connecting and conveying unit 50, and the connecting and conveying unit 50 is used to receive and convey the fruits and vegetables on the first sorting unit 40; wherein, when the weight in the first sorting unit 40 reaches a preset single portion weight, the connecting and conveying unit 50 transports the received fruits and vegetables;

[0060] A grid conveying unit 60, wherein the grid conveying unit 60 is connected to the connecting conveying unit 50, and the grid conveying unit 60 is used to receive fruits and vegetables conveyed by the connecting conveying unit 50;

[0061] The packaging unit 70 is connected to the grid conveying unit 60, and the packaging unit 70 is used for packaging fruits and vegetables.

[0062] The conveying assembly 10 is used to convey and clean 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 material guide is provided at the connection between the two, and the input end of the material guide is adapted to the output end of the conveying assembly 10 to receive multiple fruits and vegetables at the same time; the output end of the material guide is adapted to the input end of the single fruit conveying unit 20 to output a single fruit or vegetable to the single fruit conveying unit 20. Furthermore, the material guide rotates around the funnel.

[0063] The cross section of the single fruit conveying unit 20 is "V" shaped, and the single fruit conveying unit 20 supports the bottom of fruits and vegetables. Specifically:

[0064] First, the single fruit conveying unit 20 comprises two symmetrically arranged first conveying belts, which are arranged at an angle to clamp the fruits and vegetables. The two first conveying belts run at the same speed to prevent the fruits and vegetables from being worn or rolled.

[0065] Secondly, the single fruit conveying unit 20 includes two symmetrically arranged limit plates and a second conveying belt, the limit plates are arranged obliquely, the second conveying belt is placed between the limit plates, and the fruits and vegetables are placed on the second conveying belt. The limit plates are used to prevent the fruits and vegetables from falling, and the second conveying belt is used to move the fruits and vegetables.

[0066] Of course, in some implementations, the single fruit conveying unit 20 includes: a guide roller group and a chain plate; there are multiple guide roller groups, and the multiple guide roller groups are arranged along the chain plate array; the guide roller group includes: two symmetrically arranged rollers, the chain plate is placed between the two rollers, and the surface of the roller is inclined toward the chain plate. The fruits and vegetables are stably placed on the chain plate through the guide roller group.

[0067] The weighing unit 30 is placed on the single fruit conveying unit 20, and is used to weigh each fruit and vegetable passing through; specifically, the weighing unit 30 is placed below the single fruit conveying unit 20, and when the fruits and vegetables are driven by the single fruit conveying unit 20 to move above the weighing unit 30, the weighing unit 30 then weighs the individual fruits and vegetables and uploads the records.

[0068] The weighing unit 30 is an electronic weighing module. All fruits and vegetables passing through the electronic weighing module will exert pressure on the electronic weighing module, that is, the weight of the fruits and vegetables. At this time, the electronic weighing module will record this weight or send the value to the processor.

[0069] There are a plurality of the first sorting units 40, and the plurality of the first sorting units 40 are arranged in an array along the direction of the single fruit conveying unit 20, and the plurality of the first sorting units 40 are placed on one side of the single fruit conveying unit 20.

[0070] Each first sorting unit 40 corresponds to a preset single fruit weight and a preset single portion weight; the preset single fruit weight is the weight of a single fruit or vegetable, and the preset single portion weight is the weight of a plurality of fruits and vegetables packaged together.

[0071] Specifically, taking a first sorting unit 40 as an example, the preset single fruit weight corresponding to the first sorting unit 40 is 90-130g, and the corresponding preset single portion weight is 500-600g. When the weighing unit 30 detects that the single fruit weight reaches 90 to 130g, the single fruit is controlled to fall to 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.

[0072] It should also be noted that it also includes: a picking unit, and there are multiple picking units, and the multiple picking units correspond one to one with the multiple 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 individual fruits and vegetables; specifically, after the fruits and vegetables are weighed and the weight of the single fruit is obtained, when the single fruit is moved to the corresponding first sorting unit 40, the picking unit picks the fruits and vegetables.

[0073] Furthermore, after obtaining the weight of a single fruit, the single fruit can be accurately placed in the corresponding first sorting unit 40 according to the moving speed or the number of detected single fruits; specifically, after obtaining the weight of a single fruit, the single fruit is marked, and according to the moving speed of the single fruit conveying unit 20, it is calculated how long it takes for the single fruit to move to the side of the corresponding first sorting unit 40, and at the same time, the picking unit picks the single fruit.

[0074] See also Figure 6 to Figure 7The 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; fruits and vegetables enter into the containing frame 43 from the upper opening, and fruits and vegetables move out of the containing frame 43 from the lower opening.

[0075] The connecting conveying unit 50 receives the fruits and vegetables output by the lower opening. Further, when the total weight of the fruits and vegetables in the first sorting unit 40 reaches a preset single weight, the lower opening is opened and the fruits and vegetables fall into the connecting conveying unit 50. At the same time, the connecting conveying unit 50 starts and moves the fruits and vegetables to the grid conveying unit 60 mentioned below. At the same time, the upper cover body 41 closes the upper opening to prevent other fruits and vegetables from entering the accommodating frame 43.

[0076] In some embodiments, the upper cover 41 is placed in the accommodating cavity, and the accommodating cavity is divided 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 42 is opened, the upper cover 41 is closed, and the first cavity can immediately receive fruits and vegetables to improve the sorting efficiency of the first sorting unit 40.

[0077] It should be noted that the starting condition of the lower cover 42 and the connecting conveying unit 50 is that the total weight of the fruits and vegetables in the first sorting unit 40 reaches a preset single portion weight.

[0078] The grid conveying unit 60 is connected to the connecting conveying unit 50, and the grid conveying unit 60 is used to receive the fruits and vegetables conveyed by the connecting conveying unit 50; specifically, when the connecting conveying unit 50 moves a single portion of fruits and vegetables to the grid conveying unit 60, the grid conveying unit 60 has a plurality of grids (i.e., the partition frames 61 mentioned below), each grid accommodating a portion of fruits and vegetables.

[0079] Similarly, when the total weight of the fruits and vegetables in the first sorting unit 40 reaches the preset single portion weight, the grid conveying unit 60 is activated after a preset time to convey the classified fruits and vegetables to the packaging unit 70. Then the packaging unit 70 packages the fruits and vegetables.

[0080] Different from the prior art, in the above technical solution, the single fruit conveying unit 20 is connected to the output end of the conveying component 10, and is used to separate and transport the multiple fruits and vegetables output by the conveying component 10 one by one. The V-shaped single fruit conveying unit 20 ensures the one-by-one and stable conveying of fruits and vegetables, provides a precise control basis for the 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 fruits and vegetables that meet the preset single fruit weight, the fruits and vegetables will be transported to the corresponding first sorting unit 40. The first sorting unit 40 classifies and collects the fruits and vegetables according to their weight, ensuring that fruits and vegetables of the same weight are classified together, which provides convenience for subsequent packaging, and also improves the quality and consistency of the products. Thereby improving the packaging and detection efficiency of the assembly line.

[0081] According to some embodiments of the present application, referring to Figures 1 to 3 Each of the connecting conveying units 50 receives the fruits and vegetables conveyed by two of the first sorting units 40;

[0082] Each of the grid conveying units 60 receives the fruits and vegetables conveyed by the two connecting conveying units 50 .

[0083] In this embodiment, four first sorting units 40 are taken as an example for description, there are four first sorting units 40, and the four first sorting units 40 are arranged side by side; there are two connecting conveying units 50, and the output ends of the two connecting conveying units 50 are arranged opposite to each other; there is one grid conveying unit 60, and the grid conveying unit 60 is placed between the two connecting conveying units 50.

[0084] The four first sorting units 40 arranged side by side are numbered CHU02, CHU03, CHU04 and CHU05 from left to right, and the two connecting conveying units 50 are numbered DB1-01 and DB1-02 from left to right; the connecting conveying unit 50 numbered DB1-01 takes over the first sorting units 40 numbered CHU02 and CHU03, and the connecting conveying unit 50 numbered DB1-02 takes over the first sorting units 40 numbered CHU04 and CHU05.

[0085] In actual operation, when the weight of fruits and vegetables in the first sorting unit 40 reaches the preset single portion weight, the sorting unit will stop conveying fruits and vegetables to the corresponding single fruit conveying unit 20, and trigger the connecting conveying unit 50 to start working. At this time, the connecting conveying unit 50 will take over the fruits and vegetables from the sorting unit and convey them to the next link.

[0086] Since each connecting and conveying unit 50 can receive the first sorting units 40 from two alternately releasing fruits and vegetables, the fruits and vegetables can be processed and conveyed in parallel, which improves the processing capacity and efficiency of the assembly line.

[0087] Similarly, the two interconnected conveying units 50 convey the classified fruits and vegetables to the grid conveying unit 60 alternately. The grid conveying unit 60 receives the classified fruits and vegetables and conveys them to the packaging unit 70 for packaging.

[0088] In actual use, for example, at 0s, the first sorting unit 40 numbered CHU02 is full of packages, triggering the lower cover 42 of the first sorting unit 40 numbered CHU02 to open and release the goods, and at the same time triggering the connection conveying unit 50 numbered DB1-01 to run, setting the first sorting unit 40 numbered CHU02 to release the goods time is 0.5s, and setting the running time of the connection conveying unit 50 numbered DB1-01 to 1.5s, which is equivalent to that within 1s, all the goods on the first sorting unit 40 numbered CHU02 need to be transported to the grid conveying unit 60 (the length of the connection conveying unit 50 is 1m, and the speed is 1m / s). At 1.5s, the grid conveying unit 60 runs and conveys forward for 0.5s (transporting the next grid to the waiting place, the grid length is 0.3m, and the speed of the grid conveying unit 60 is 0.6m / s). At 2s, the first sorting unit 40 numbered CHU02 is opened and released. 04 is full of packages, triggering the lower cover 42 of the first sorting unit 40 numbered CHU04 to open and release the goods, and at the same time 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 is equivalent to conveying all the goods on the first sorting unit 40 numbered CHU04 to the grid conveying unit 60 within 1s (the length of the connection conveying unit 50 is 1m, and the speed is 1m / s), at 3.5s, the grid conveying unit 60 runs and conveys forward for 0.5s (conveys the next grid to the waiting place, the grid length is 0.3m, and the grid conveyor speed is 0.6m / s), at 4s, the first sorting unit 40 numbered CHU03 is full of packages... and so on.

[0089] According to some embodiments of the present application, referring to Figure 3 The grid conveying unit 60 includes: a partition frame 61 and a driving member 62, wherein the driving member 62 is transmission-connected with a plurality of the partition frames 61, and the partition frames 61 are used to receive and transport the fruits and vegetables output by the connection conveying unit 50;

[0090] When a connecting conveying unit 50 is transporting fruits and vegetables, a partition frame 61 is placed on the output end side of the connecting conveying unit 50 that transports fruits and vegetables to receive the fruits and vegetables.

[0091] The driving member 62 includes a roller and a belt. There are two rollers, which are arranged at an interval, 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.

[0092] According to some embodiments of the present application, referring to Figure 1 , the conveying assembly 10 comprises:

[0093] Multiple quality inspection stations 11;

[0094] A first conveying unit 12, wherein the plurality of quality inspection tables 11 are placed on both sides of the first conveying unit 12, and the first conveying unit 12 is used to receive fruits and vegetables after quality inspection;

[0095] The second conveying unit 13 is disposed at one side of the output end of the first conveying unit 12 , and is used for receiving fruits and vegetables on the first conveying unit 12 .

[0096] The second conveying unit 13 is arranged obliquely, and is used to filter impurities mixed in fruits and vegetables;

[0097] 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 quality inspection tables 11 are placed at the beginning of the assembly line to perform preliminary quality inspection on the fruits and vegetables entering the assembly line. Quality inspectors can select, classify and mark the fruits and vegetables on these quality inspection tables 11 to ensure that only fruits and vegetables that meet the quality standards can enter the subsequent conveying and processing links.

[0098] The first conveying unit 12 is used to receive the fruits and vegetables after quality inspection. This conveying unit can be a belt conveyor, a roller conveyor or other suitable conveying equipment to convey the fruits and vegetables to the next link at a stable speed.

[0099] The second conveying unit 13 is located at the output end of the first conveying unit 12, and is used to further receive and convey fruits and vegetables. Different from 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 and soil mixed therein during the conveying process.

[0100] The specific structure of the second conveying unit 13 includes a plurality of rollers 131 arranged in an array along the transport direction. The spacing between the rollers 131 can be adjusted according to the type and size of the fruits and vegetables to ensure the best conveying effect and impurity filtering effect, that is, the impurities fall from the gaps between the rollers 131.

[0101] In actual use, fruits and vegetables are first placed on the quality inspection table 11, and the quality inspectors conduct a preliminary quality inspection. After being selected, classified and marked, qualified fruits and vegetables are placed on the first conveying unit 12. The first conveying unit 12 conveys the fruits and vegetables to the second conveying unit 13 at a stable speed. In this process, the fruits and vegetables are smoothly conveyed to the next link, while avoiding damage and confusion during the conveying process.

[0102] When the fruits and vegetables enter the second conveying unit 13, due to the inclined setting of the second conveying unit 13, the fruits and vegetables will slide down along the inclined surface of the roller 131 under the action of gravity. In this process, impurities such as leaves and soil mixed in the fruits and vegetables fall from the gaps between the rollers 131 and remain at the bottom of the second conveying unit 13. Further, in some embodiments, the surface of the roller 131 is a concave-convex surface.

[0103] The conveying assembly 10 can more effectively convey and process fruits and vegetables, thereby improving production efficiency and product quality.

[0104] According to some embodiments of the present application, referring to Figure 2 , also includes:

[0105] The cache unit 80 is connected to the packaging unit 70, and the cache unit 80 is used to receive the packaged fruits and vegetables.

[0106] The specific implementation of the cache unit 80 can be one or more storage areas, which can be fixed shelves, mobile pallet trucks, or automated storage systems. The size and number of the cache units 80 can be flexibly configured according to the type and quantity of fruits and vegetables and the processing capacity of the assembly line.

[0107] Specifically, the packaged fruits and vegetables need to be manually transferred to the finished product area. To avoid the accumulation of the packaged fruits and vegetables, the fruits and vegetables that cannot be transferred in time will be placed in the buffer unit 80; preferably, the buffer unit 80 is a slowly rotating disc.

[0108] In actual operation, first, 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 grid conveying unit 60 on the assembly line, and finally arrive at the packaging unit 70. In the packaging unit 70, the fruits and vegetables are packaged according to the predetermined specifications and quantity. The packaged fruits and vegetables are transported to the buffer unit 80. In this process, the staff or the automated system of the buffer unit 80 will place the fruits and vegetables in the appropriate storage area according to the type, quantity and storage requirements of the fruits and vegetables.

[0109] According to some embodiments of the present application, referring to Figures 4 to 5 , and also includes: a visual inspection unit 90, the visual inspection unit 90 has a built-in inspection channel for the single fruit conveying unit 20 to pass through, the single fruit conveying unit 20 is placed in the inspection channel, and the visual inspection unit 90 is used to detect fruits and vegetables on the single fruit conveying unit 20.

[0110] The visual inspection unit 90 has a built-in inspection channel, and the single fruit conveying unit 20 is completely placed in this inspection channel.

[0111] The core components of the visual inspection unit 90 generally include a high-precision camera, an image processor, and corresponding control software. The camera is responsible for capturing the image of each fruit or vegetable on the single fruit conveying unit 20, while the image processor analyzes and processes these images quickly and accurately. The control software is responsible for coordinating the entire visual inspection process to ensure the accuracy and efficiency of the inspection.

[0112] The design of the inspection channel fully considers the characteristics and inspection requirements of fruits and vegetables, and has appropriate width and height to ensure that fruits and vegetables can pass smoothly without any obstruction. At the same time, the interior of the inspection channel is also equipped with appropriate lighting equipment to ensure that the camera can capture clear and bright images.

[0113] During the operation, first, fruits and vegetables are conveyed to the single fruit conveying unit 20 through the conveying assembly 10. Driven by the single fruit conveying unit 20, the fruits and vegetables pass through the detection channel of the visual inspection unit 90 in sequence at a certain speed and spacing. When the fruits and vegetables enter the detection channel, the camera will immediately capture their images. Since the camera has high precision and high resolution, it can capture the subtle features and defects on the surface of fruits and vegetables. The captured image is transmitted to the image processor for further analysis and processing. The image processor uses advanced algorithms and technologies to identify, classify and judge the image. It can identify information such as the type, size, shape, and surface flaws and defects of fruits and vegetables. After analysis and processing, the image processor will feed back the results to the control system of the assembly line. The control system further sorts, processes or marks the fruits and vegetables based on this information. If the visual inspection 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, qualified fruits and vegetables will continue to be weighed, sorted, transported in connections, transported by grids and packaged along the assembly line.

[0114] By adding the visual inspection unit 90, comprehensive, rapid and accurate inspection of fruits and vegetables can be achieved. This can not only improve the quality and safety of fruits and vegetables, but also reduce manual intervention and production costs. At the same time, this design also makes the production line more intelligent and automated, and can adapt to the inspection needs of fruits and vegetables of different types and specifications.

[0115] According to some embodiments of the present application, referring to Figure 5 , and also includes: 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 inspection 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.

[0116] The second sorting unit 100 is used to receive and process damaged fruits and vegetables dropped from the single fruit conveying unit 20 .

[0117] The second sorting unit 100 is a sorting mechanism with a receiving port, which 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 dropped from the single fruit conveying unit 20 .

[0118] In order to ensure that the second sorting unit 100 can accurately receive and process damaged fruits and vegetables, the control system of the assembly line needs to work closely with the visual inspection unit 90. When the visual inspection 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 immediately trigger the single fruit conveying unit 20 to convey the damaged fruits and vegetables to the receiving port of the second sorting unit 100.

[0119] Specifically, fruits and vegetables pass through the single fruit conveying unit 20. Driven by the single fruit conveying unit 20, the fruits and vegetables pass through the additional visual inspection unit 90 on the assembly line in turn. In this process, the visual inspection unit 90 will perform a detailed inspection on each fruit and vegetable to identify whether there is damage or defect. When the visual inspection unit 90 detects damaged fruits and vegetables, it will immediately send a signal to the control system of the assembly line. This signal contains information such as the location, type and degree of damage of the damaged fruits and vegetables.

[0120] After receiving the signal from the visual inspection unit 90, the control system will immediately adjust the single fruit conveying unit 20. Specifically, the control system will control the conveying speed, direction, stop position and other parameters of the single fruit conveying unit 20 to ensure that the damaged fruits and vegetables can be accurately conveyed to the receiving port of the second sorting unit 100.

[0121] According to some embodiments of the present application, referring to Figure 3 , further comprising: a reflux unit 110;

[0123] The return unit 110 is used to process the fruits and vegetables that have not been successfully sorted by the first sorting unit 40 and the second sorting unit 100, to ensure that they can re-enter the assembly line for further processing or sorting.

[0124] The input end of the return unit 110 is connected to the output end of the single fruit conveying unit 20, and is used to receive fruits and vegetables that have not been accepted by the first sorting unit 40 and the second sorting unit 100. The output end is connected to the input end of the conveying assembly 10 to ensure that these fruits and vegetables can re-enter the assembly line.

[0125] The reflux unit 110 is internally equipped with a conveyor belt or a roller to ensure that the fruits and vegetables can be smoothly and quickly transported from the input end to the output end.

[0126] In actual use, first, fruits and vegetables are conveyed to the single fruit conveying unit 20 through the conveying assembly 10. Driven by the single fruit conveying unit 20, the fruits and vegetables are weighed by the weighing unit 30 in turn, 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 certain fruit or vegetable passes by when the first sorting unit 40 is closed, the fruit or vegetable will not be pushed in, and it will continue to move forward along the single fruit conveying unit 20 and finally be conveyed to the input end of the reflux unit 110.

[0127] The fruits and vegetables entering the return unit 110 will be transported to the output end and re-enter the conveying assembly 10. At this time, they will pass through the entire assembly line again for weighing, sorting and other processing processes.

[0128] By adding the return unit 110, the automatic return processing of unsorted fruits and vegetables can be realized, which can not only improve the processing efficiency and accuracy of the assembly line, but also reduce manual intervention and reduce production costs.
