Description

Technical Field

[0001] This invention relates to the field of fresh fruit packaging equipment technology, specifically to a three-station horizontal stepping packaging method for fresh fruit. Background Technology

[0002] Fruit spoilage mainly occurs during harvesting, packaging, and transportation. Transportation is the primary cause of spoilage. Therefore, reducing spoilage during transportation has become a pressing issue for the fruit industry. For example, after sorting, fresh fruits like plums or apricots are typically packaged with foamed plastic netting to minimize spoilage during transport. Using foamed plastic netting significantly improves the quality and appearance of the fruit, reduces spoilage during transportation, and enhances its marketability and competitiveness.

[0003] According to surveys, processing enterprises and farmers' cooperatives typically purchase Saimaiti apricots from farmers through order-based purchases at 10 yuan / kg. After sorting and processing with net bags, they can be sold for 35-40 yuan / kg. Prunes, on the other hand, are generally priced at 10-20 yuan / kg, but after sorting and processing with net bags, they can be sold for 30-40 yuan / kg. This demonstrates that sorting and processing with net bags significantly improves the economic benefits of fresh fruits such as apricots and prunes.

[0004] However, the current process of bagging fresh fruit largely relies on manual labor. The efficiency of manual sorting and bagging of apricots is approximately 15-20 kg / hour; for plums, it's about 4-6 kg / hour. During peak fruit harvest season, the efficiency of manual bagging can easily restrict production output and delay the market launch of the fruit.

[0005] To improve the efficiency of bagging operations, those skilled in the art have developed some semi-automated fresh fruit packaging equipment or auxiliary tools, such as the fruit packaging conveyor component and fruit packaging device disclosed in Chinese patent document CN116135709A. This fruit packaging device utilizes a fruit packaging conveyor component to keep the fruit stationary relative to the ground during bagging, thus eliminating the need to open the component while simultaneously moving synchronously with the conveyor belt. This improves the accuracy of bagging the fruit when the component is opened and facilitates long-distance transport of the bagged fruit.

[0006] However, the aforementioned fruit packaging equipment uses intermittent packaging, elastic component positioning, and single-station operation with long pause times, resulting in a prolonged cycle time. This places high demands on the power source and operational stability of the bag-supporting mechanism, and also has very low tolerance for the size of the fruit to be packaged. During operation, it is prone to production cycle disruptions or even shutdowns, and its efficiency may even be lower than manual bagging. Especially in multi-station collaborative packaging scenarios, existing packaging equipment struggles to achieve simultaneous packaging at multiple stations within the same conveying unit, making it difficult to break through the upper limit of packaging efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a packaging method for the process of fresh fruit packaging, so as to realize the automated multi-station collaborative net bagging operation of fresh fruit, solve the technical problems of high labor intensity and high production cost of manual net bagging of fresh fruit, and improve the efficiency of net bagging.

[0008] To achieve the above objectives, the present invention adopts the following solution:

[0009] A method for packaging fresh fruit in a three-station horizontal stepping manner includes the following steps:

[0010] Fresh fruit is transported in batches, one by one into the placement chamber of the conveying unit. The fresh fruit is arranged in a straight line in the conveying plane along the conveying direction of the conveying unit. The conveying unit performs step-by-step conveying of the fresh fruit, so that the fresh fruit stops below the packing station. The three packing stations are arranged linearly along the conveying direction of the conveying unit. When the fresh fruit reaches below the packing station, the conveying unit stops conveying and waits for the fresh fruit to be packed.

[0011] The foamed mesh bag is conveyed by the mesh bag clamping unit to the set station, so that the opening of the foamed mesh bag faces the conveying plane.

[0012] The fresh fruit is lifted up, the conveying unit stops conveying, and the lifting component located below the conveying unit lifts the fresh fruit in the placement cavity out of the conveying plane and sends the fresh fruit to the packaging station.

[0013] In the bag-supporting packaging, each set station is equipped with a bag-supporting unit. The bag-supporting component in the bag-supporting unit opens the bag opening of the foam net bag. When the telescopic component drives the bag-supporting component to move from the first position to the second position, the foam net bag is pulled and stretched into the set station. The lifting component continues to feed the fresh fruit into the foam net bag.

[0014] Cut the foamed mesh bag. When the telescopic component drives the bag-supporting component to the second position, the bag-supporting component releases the opening of the foamed mesh bag. The cutting component, located between the packing station and the mesh bag clamping unit, cuts the foamed mesh bag radially, completing the packing of fresh fruit.

[0015] The lifting component retracts below the conveying plane, and the conveying unit continues to start, conveying the next fresh fruit to below the packaging station.

[0016] Preferably, the first position is located at the discharge port of the mesh bag clamping unit, and the second position is located between the assembly station and the conveying plane.

[0017] Preferably, as the fresh fruit is arranged in a straight line along the conveying direction of the conveying unit in the conveying plane, the conveying unit is also used to adjust the posture of the fresh fruit so that the fresh fruit is lying flat in the placement cavity. When the fresh fruit is lying flat, the fruit axis passing through both ends of the fresh fruit points radially toward the foamed mesh bag.

[0018] As a preferred option, in the initial stage of conveying fresh fruit, when the first station is carrying out the packaging operation, the other two stations are idle. The conveying unit takes the first station as the reference. After the first station completes the packaging of the first fresh fruit, the conveying unit steps forward to convey three placement chambers and then pauses to ensure that the placed fresh fruit can quickly reach the subsequent second and third stations.

[0019] Preferably, after the fresh fruit is packaged, a collection step is also included. In the collection step, the fruit pushing component pushes the packaged fresh fruit into a collection box located on one side of the conveying unit.

[0020] The present invention provides a three-station lateral stepping packaging method for fresh fruit, which, compared with the prior art, has the following outstanding substantive features and significant progress: This method utilizes a mesh bag conveying unit to transport foamed mesh bags to the packing station. The bag-supporting component in the bag-supporting unit opens the opening of the foamed mesh bag. When the telescopic component drives the bag-supporting component to move from the first position to the second position, the foamed mesh bag is pulled and stretched into the packing station. The lifting component continues to feed the fresh fruit into the foamed mesh bag, completing one packing process. This fresh fruit mesh bag packing machine realizes automated fresh fruit mesh bag packing operations, solving the technical problems of high labor intensity and high production costs associated with manual mesh bag packing of fresh fruit. It facilitates the sequential arrangement of multiple packing stations along the conveying direction of the conveying unit, forming a structure of multiple packing stations cooperating in packaging, greatly improving the efficiency of fresh fruit mesh bag packing and breaking through the upper limit of fresh fruit packaging efficiency.

[0035] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Currently, the post-harvest processing level of fresh fruit is relatively low. For example, fruit sorting and bagging are almost entirely done manually, resulting in high labor intensity, low efficiency, and high production costs. Only a small portion of fruit sorting utilizes traditional mechanical sorting, and bagging is done using semi-automated packaging equipment. This, due to the instability of the equipment and the precision required, easily damages the fruit. To accelerate the transformation of fruit production methods and improve the quality and efficiency of the industry, mechanization is urgently needed to support large-scale efficiency and promote standardized high-quality development. Especially in the field of fresh fruit packaging, there is an urgent need for the promotion and application of intelligent technology and equipment to improve the efficiency of bagging fruit, enhance the marketability of the fruit, and achieve added value through processing.

[0037] like Figure 1-8 As shown in the figure, this invention proposes a fresh fruit net bagging machine, which aims to automate the net bagging operation of fresh fruit, solve the technical problems of high labor intensity and high production cost of manual net bagging of fresh fruit, and improve the efficiency of net bagging.

[0038] This invention discloses a fresh fruit net bag packing machine that utilizes a bag clamping unit to convey foamed net bags to a packing station. The bag-supporting component in the bag-supporting unit opens the opening of the foamed net bag. When the telescopic component drives the bag-supporting component to move from a first position to a second position, the foamed net bag is pulled and stretched into the packing station. The lifting component continues to feed the fresh fruit into the foamed net bag, completing one packing process. This fresh fruit net bag packing machine automates the net bag packing operation, solving the technical problems of high labor intensity and high production costs associated with manual net bag packing of fresh fruit, and improving the efficiency of fresh fruit net bag packing.

[0039] Fresh Fruit Mesh Bag Set Machine

[0040] like Figure 1 As shown, a fresh fruit net bag packing machine includes a conveying unit 1, a lifting assembly 2, a net bag clamping unit 3, a bag supporting unit 4, and a cutting assembly 5.

[0041] like Figure 1 Combination Figure 2 As shown, conveying unit 1 is used to convey fresh fruit. Conveying unit 1 defines a conveying plane 6. The fresh fruit is arranged in a straight line within the conveying plane 6 along the conveying direction of conveying unit 1. A placement cavity 7 for supporting the fresh fruit is provided on the conveying plane 6. Figure 3 As shown, a set-up station 8 is provided above the conveyor plane 6.

[0042] For example, conveyor unit 1 uses a conveyor chain device. The conveyor chain device is equipped with roller assemblies for supporting fresh fruit. The conveyor chain device drives the roller assemblies to rotate, continuously transporting the fresh fruit located in the feeding area to below the packaging station 8. A placement cavity 7 for supporting the fresh fruit is formed between adjacent roller assemblies.

[0043] like Figure 1 As shown, the lifting assembly 2 is used to lift the fresh fruit in the placement cavity 7 out of the conveying plane 6. The lifting assembly 2 defines the lifting direction. For example, the conveying unit 1 conveys the fresh fruit in a horizontal plane, and the lifting direction of the lifting assembly 2 is perpendicular to the horizontal plane. The lifting direction can also be appropriately adjusted according to the angle formed by the conveying plane 6 and the horizontal plane to smoothly lift the fresh fruit out of the conveying plane 6 and prevent the fresh fruit from falling during its entry into the packaging station 8.

[0044] like Figure 3 As shown, the mesh bag conveying unit 3 is used to convey foamed mesh bags to the set-up station 8, with the bag opening facing the conveying plane 6. For example, the mesh bag conveying unit 3 is located above the set-up station 8. The mesh bag conveying unit 3 includes a storage rack 31 for storing foamed mesh bags, forming a feeding channel 415 between the storage rack 31 and the set-up station 8. A first clamping plate assembly 32, a second clamping plate assembly 33, and a clamping roller assembly 34 are arranged within the feeding channel 415. The clamping roller assembly 34 is located between the first clamping plate assembly 32 and the second clamping plate assembly. The clamping roller assembly 34 is used to provide conveying traction for the foamed mesh bags. The first clamping plate assembly 32 is located between the storage rack 31 and the clamping roller assembly 34.

[0045] During the conveying of foamed mesh bags by the mesh bag clamping unit 3, both the first clamping plate assembly 32 and the second clamping plate assembly 33 clamp or release the foamed mesh bags. When the mesh bag clamping unit 3 is in use, the second clamping plate assembly 33 clamps the foamed mesh bag, the first clamping plate assembly 32 releases the foamed mesh bag, and the clamping roller assembly 34 rotates, thereby driving the foamed mesh bag to move towards the second clamping plate assembly 33. Some of the foamed mesh bags in the storage rack 31 are conveyed out, and the foamed mesh bags are compressed between the second clamping plate assembly 33 and the clamping roller assembly 34. The length of the compressed foamed mesh bag is sufficient for packaging a single fresh fruit. Subsequently, the first clamping plate assembly 32 clamps the foamed mesh bag, and the second clamping plate assembly 33 releases the foamed mesh bag, so that the opening of the foamed mesh bag faces the packaging station 8, which facilitates the subsequent bag-opening and packaging operation.

[0046] like Figure 1 Combination Figure 3 As shown, the cutting assembly 5 is located between the packing station 8 and the mesh bag feeding unit 3. The cutting assembly 5 is used to cut the foam mesh bag.

[0047] like Figure 3As shown, the bag-supporting unit 4 includes a bag-supporting assembly 41 for supporting the opening of the foam mesh bag, and a telescopic assembly 42 for driving the bag-supporting assembly 41 to reciprocate along the lifting direction. The bag-supporting assembly 41 has a first position and a second position in the lifting direction. The telescopic assembly 42 drives the bag-supporting assembly 41 to reciprocate between the first position and the second position.

[0048] The first position is located at the discharge port of the mesh bag clamping unit 3, and the second position is located between the assembly station 8 and the conveying plane 6. In the first position, the bag-supporting assembly 41 opens the opening of the foam mesh bag; when the telescopic assembly 42 drives the bag-supporting assembly 41 to move from the first position to the second position, the foam mesh bag is pulled and stretched into the assembly station 8, and the lifting assembly 2 lifts the fresh fruit out of the conveying plane 6 and feeds the fresh fruit into the foam mesh bag; in the second position, the cutting assembly 5 cuts the foam mesh bag radially.

[0049] When using the fresh fruit mesh bag packaging machine proposed in this embodiment of the invention, it is combined with... Figure 5 As shown, it includes the following steps:

[0050] Fresh fruit is transported in batches, one by one into the placement cavity 7 of the conveying unit 1. The fresh fruit is arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. The conveying unit 1 performs step-by-step conveying of the fresh fruit, so that the fresh fruit stops below the packaging station 8. When the fresh fruit reaches the bottom of the packaging station 8, the conveying unit 1 stops conveying and waits for the fresh fruit to be packaged.

[0051] The foamed mesh bag is conveyed by the mesh bag clamping unit 3 to the set station 8, so that the opening of the foamed mesh bag faces the conveying plane 6.

[0052] The fresh fruit is lifted, the conveying unit 1 stops conveying, the lifting component 2 lifts the fresh fruit in the placement cavity 7 out of the conveying plane 6, and sends the fresh fruit to the packaging station 8.

[0053] The bag is opened by the bag opening component 41. When the telescopic component 42 drives the bag opening component 41 to move from the first position to the second position, the foam net bag is pulled and stretched into the set station 8. The lifting component 2 continues to feed the fresh fruit into the foam net bag.

[0054] When the telescopic component 42 drives the bag-supporting component 41 to the second position, the bag-supporting component 41 releases the opening of the foam net bag, and the cutting component 5 cuts the foam net bag radially, thus completing the packaging of the fresh fruit.

[0055] The lifting component 2 retracts below the conveying plane 6, and the conveying unit 1 continues to start, conveying the next fresh fruit to below the set station 8.

[0056] The fresh fruit mesh bag packaging machine proposed in this embodiment utilizes the cooperation of a lifting component 2 and a conveying unit 1. The conveying unit 1 continuously transports fresh fruit to the area below the packaging station 8, while the lifting component 2 sequentially feeds the fresh fruit, arranged in a straight line along the conveying direction of the conveying unit 1, into the packaging station 8. The packaging path of the fresh fruit intersects with the conveying direction of the conveying unit 1 only once in the placement cavity 7, greatly reducing the risk of interference between the packaging station and the conveying unit 1. This is beneficial for further improving the safety and stability of equipment operation, optimizing existing semi-automatic fresh fruit packaging equipment, avoiding packaging rhythm disruptions during the fresh fruit packaging process, and improving packaging efficiency.

[0057] To further improve the collection efficiency of packaged fresh fruit, a collection box for collecting packaged fresh fruit is set on one side of the conveying unit 1, and the collection box corresponds one-to-one with the packaging station 8.

[0058] [Conveying Unit]

[0059] like Figure 10 As shown, conveyor unit 1 uses a conveyor chain device. The conveyor chain device is equipped with roller assemblies to support the fresh fruit. The conveyor chain device drives the roller assemblies to rotate, continuously transporting the fresh fruit located in the feeding area to below the packaging station 8. Pallets for placing the fresh fruit are provided between adjacent roller assemblies.

[0060] like Figure 10 As shown, taking apples as an example, typically, the apple's end contacts the tray, and the fruit's axis, passing through both ends, points towards the opening of the foam mesh bag. In this way, after the apple is packaged in this position, the foam mesh bag completes the packaging along the fruit's axis. Since the ends of the foam mesh bag are all open, it only utilizes the elasticity of the foam mesh bag itself to create a contraction at the apple's end, lacking protection for the apple's end.

[0061] To further enhance the protective effect of foam mesh bags on fresh fruit, especially for fruits with structures similar to apricots and plums. For example... Figure 11 As shown, when the conveying unit 1 continuously transports the fresh fruit located in the feeding area to the bottom of the set station 8, the fresh fruit is arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. Under the action of gravity and friction, the fresh fruit will make adaptive adjustments to its own posture, so that the fruit body is in a flat state in the placement cavity, that is, the fruit body axis passing through both ends of the fruit body points to the end of the roller assembly.

[0062] In this way, as Figure 11As shown, taking plums as an example, during the process of transporting plums from the feeding area to below the packaging station 8, the posture of the fruit is adjusted so that it lies flat in the placement cavity. After the foam net bag completes the packaging of the plums, the side wall of the foam net bag effectively protects the ends of the plums.

[0063] like Figure 12 As shown, the roller assembly is arranged linearly along the conveying direction of conveying unit 1. The roller assembly includes a first conical roller and a second conical roller. The first and second conical rollers are coaxially arranged, with the tips of the first and second conical rollers facing each other, so that the sidewalls of the first and second conical rollers form a bracket-shaped support contour for the fruit. This creates a rhomboid placement cavity structure between adjacent roller assemblies, facilitating the natural adjustment of the fruit's posture to a lying position during conveying, thereby improving the protective effect of the foamed mesh bag on the fruit's ends after packaging.

[0064] [Lifting Components]

[0065] like Figure 5 Combination Figure 6 As shown, the lifting assembly 2 is located below the conveying unit 1. The lifting assembly 2 includes a support frame 21, a lifting cylinder 22, and a tray 23 for lifting fresh fruit through the placement cavity 7. The lifting cylinder 22 is arranged perpendicular to the conveying plane 6. The cylinder body of the lifting cylinder 22 is mounted on the support frame 21. The piston rod of the lifting cylinder 22 is connected to the tray 23. Figure 6 The direction indicated by the dashed arrow shown is the lifting direction of the lifting component 2.

[0066] When in use, the lifting component 2 works in conjunction with the conveying unit 1. When the conveying unit 1 transports the fresh fruit to below the packaging station 8, the conveying unit 1 pauses transporting, and the lifting cylinder 22 actuates to lift the tray 23, lifting the fresh fruit in the placement cavity 7 out of the conveying plane 6 and sending the fresh fruit to the packaging station 8. After the fresh fruit is packaged in the packaging station 8, the lifting cylinder 22 actuates to retract the tray 23 to below the conveying plane 6, and the conveying unit 1 resumes operation, transporting the next fresh fruit to below the packaging station 8.

[0067] [Bag support components]

[0068] like Figure 7As shown, the bag-supporting assembly 41 includes a connecting frame 411, a parallel gripper cylinder 412, and a limiting plate 414. The connecting frame 411 has a connecting portion for connecting the telescopic assembly 42. A channel 415 for the passage of fresh fruit is provided on one side of the connecting frame 411. The cylinder body of the parallel gripper cylinder 412 is mounted on the connecting frame 411. The grippers 413 of the parallel gripper cylinder 412 are located within the channel 415, and the pair of grippers 413 open within the channel 415 to expand the opening of the foam mesh bag. The limiting plate 414 is arranged parallel to the grippers 413 and located outside the pair of grippers 413.

[0069] like Figure 4 Combination Figure 7 As shown, the telescopic assembly 42 includes a power cylinder 421, a guide rail 422, a slide 423, and a mounting plate 424. The axis of the power cylinder 421 is arranged parallel to the lifting direction. The guide rail 422 is arranged parallel to the power cylinder 421. The slide 423 is embedded in the guide rail 422. One end of the mounting plate 424 is connected to the slide 423, and the other end of the mounting plate 424 is connected to the connecting part of the connecting frame 411. The piston rod of the power cylinder 421 is connected to the mounting plate 424.

[0070] Cut-off component]

[0071] like Figure 8 As shown, the cutting assembly 5 includes a frame 51, a cutting wire 52 for electrically heated operation, and a cutting cylinder 53. The cutting cylinder 53 is arranged perpendicular to the lifting direction. The cutting cylinder 53 drives the frame 51 to reciprocate radially along the foamed mesh bag. The frame 51 is connected to the piston rod of the cutting cylinder 53. The cutting wire 52 is mounted on the frame 51.

[0072] To facilitate the removal of packaged fresh fruit from the packaging station 8, a fruit-pushing assembly is provided on the inner side of the frame 51 for pushing the packaged fresh fruit out of the packaging station 8. The fruit-pushing assembly includes a push plate 54 and a fruit-pushing cylinder. The fruit-pushing cylinder is arranged parallel to the cutting cylinder 53. The cylinder body of the fruit-pushing cylinder is mounted on the frame 51. The push plate 54 is connected to the piston rod of the fruit-pushing cylinder. For example, after the fresh fruit is packaged, a collection step is also included. In the collection step, the fruit-pushing assembly pushes the packaged fresh fruit into a collection box located on one side of the conveying unit 1.

[0073] Three-station fresh fruit mesh bag making machine

[0074] To further improve the packaging efficiency of fresh fruit, such as Figure 3As shown, above the conveying unit 1, the equipment can be configured with multiple packaging stations 8 according to the quantity of fresh fruit arriving in batches. Taking a three-station fresh fruit net bag packaging machine as an example, the three packaging stations 8 are arranged linearly along the conveying direction of the conveying unit 1, and the lifting components 2 correspond one-to-one with the packaging stations 8 below the conveying unit 1. During the step-like conveying process of the conveying unit 1, when the conveying unit 1 pauses conveying, the three packaging stations 8 can operate to complete the packaging of three fresh fruits.

[0075] [Step-by-step three-station collaborative packaging method]

[0076] In this embodiment of the invention, a fresh fruit mesh bagging machine, taking fresh plums as an example, employs a three-station step-conveying packaging method for bagging. Combined with... Figure 9 As shown, batches of fresh fruit enter the placement cavity 7 of the conveying unit 1 one by one, and the fresh fruit are arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. The conveying unit 1 performs step-by-step conveying of the fresh fruit, so that the fresh fruit stops below the packaging station 8. When the fresh fruit reaches the bottom of the packaging station 8, the conveying unit 1 stops conveying and waits for the fresh fruit to be packaged.

[0077] like Figure 13 As shown, a three-station horizontal stepping packaging method for fresh fruit includes the following steps:

[0078] Fresh fruit is transported in batches, one by one into the placement chamber of the conveying unit. The fresh fruit is arranged in a straight line on the conveying plane along the conveying direction of the conveying unit. The conveying unit performs step-by-step conveying of the fresh fruit, so that the fresh fruit stops below the packing station. The three packing stations are arranged linearly along the conveying direction of the conveying unit. When the fresh fruit reaches below the packing station, the conveying unit stops conveying and waits for the fresh fruit to be packed.

[0079] As the fresh fruit is arranged in a straight line along the conveying direction of the conveying unit in the conveying plane, the conveying unit is also used to adjust the posture of the fresh fruit so that the fruit is lying flat in the placement cavity. When the fresh fruit is lying flat, the fruit axis passing through both ends of the fruit points radially toward the foamed mesh bag.

[0080] In the initial stage of conveying fresh fruit, when the first station is packaging, the other two stations are idle. The conveying unit takes the first station as the reference. After the first station completes the packaging of the first fresh fruit, the conveying unit steps forward to convey three placement chambers and then pauses to ensure that the placed fresh fruit can quickly reach the subsequent second and third stations.

[0081] The foamed mesh bags are conveyed by the mesh bag clamping unit to the set station, with the bag opening facing the conveying plane.

[0082] The fresh fruit is lifted, the conveying unit stops conveying, and the lifting component located below the conveying unit lifts the fresh fruit in the placement cavity out of the conveying plane and sends the fresh fruit to the packaging station.

[0083] In the bagging process, each packing station is equipped with a bag-supporting unit. The bag-supporting component in the unit opens the opening of the foam mesh bag. When the telescopic component drives the bag-supporting component to move from the first position to the second position, the foam mesh bag is pulled and stretched into the packing station. The lifting component continues to feed the fresh fruit into the foam mesh bag. The first position is located at the discharge port of the mesh bag clamping unit, and the second position is located between the packing station and the conveyor plane.

[0084] When the telescopic component drives the bag-supporting component to the second position, the bag-supporting component releases the opening of the foam net bag. The cutting component, located between the packing station and the bag clamping unit, cuts the foam net bag radially, completing the packing of the fresh fruit.

[0085] The lifting component retracts below the conveying plane, and the conveying unit continues to start, conveying the next fresh fruit to below the packaging station.

[0086] After the fresh fruit is packaged, there is a collection step. In the collection step, the fruit pushing component pushes the packaged fresh fruit into the collection box located on one side of the conveying unit.

[0087] For example, such as Figure 9 As shown, when the three-station fresh fruit net bagging machine initially operates, the fresh fruit cannot completely fill every placement cavity 7 on the conveying plane 6. While the first station is packaging, the other two stations are idle. To quickly enter the state of three-station collaborative operation, the conveying unit 1, during step-by-step conveying, uses the first station as a reference. After the first station completes the packaging of the first fresh fruit, the conveying unit 1 steps through three placement cavities 7 and then pauses. This ensures that the placed fresh fruit can quickly reach the subsequent second and third stations, thereby enabling the equipment to quickly enter the state of three-station collaborative operation.

[0088] The fresh fruit net bagging machine proposed in this embodiment of the invention can realize operations such as feeding fresh fruit one by one, net bagging fresh fruit, and cutting net bags, with an operating speed of 40-50 pieces / minute. Taking plums as an example, the production efficiency technical indicators of the fresh fruit net bagging machine are 2000-3000 pieces / hour, with a matching power of 1.5kw. During the conveying process, the fresh fruit is sequentially sorted and conveyed to the receiving system. The net bagging system, driven by a moving cylinder, clamps, supports, and conveys the net bags, realizing the net bagging operation. Finally, the net bag is cut by the net cutting system, achieving the goal of precise, efficient, non-destructive, and intelligent bagging. The control system adopts PLC control, using sensor detection technology to detect the operating status of the conveying system and the net bagging status, thereby enabling real-time monitoring and control via the PLC to ensure stable system operation. The project improves the imported technology and equipment to adapt to the intelligent bagging operation of fresh fruits such as apricots and plums, solving the technical problems of high labor intensity and high production cost of manual bagging of fresh fruits, and realizing precise, efficient and intelligent bagging operation.
