Description

Technical Field

[0001] The invention relates to the technical field of fresh fruit packaging equipment, and in particular to a fresh fruit net bag packaging machine and a packaging method. Background Art

[0002] The loss of fresh fruits mainly occurs in the process of picking, packaging, and transportation. Among them, the transportation process is the main cause of fresh fruit loss. As a result, how to reduce the loss of fresh fruits in the transportation process has become a problem that the fruit industry needs to solve urgently. For example, after fresh fruits such as prunes or apricots are sorted, plastic foam nets are usually used to wrap the fruit bodies in order to reduce losses during transportation. The use of plastic foam nets to package fresh fruits can greatly improve the quality and appearance of fresh fruits, reduce the loss rate in the transportation process, and enhance the commodity and market competitiveness of fruits.

[0003] According to the investigation, processing enterprises and farmers' cooperatives purchase Saimati apricots from farmers through orders, usually at 10 yuan / kg. After sorting and net bagging, they can be sold for 35-40 yuan / kg. The common price of prunes is about 10-20 yuan / kg. After sorting and net bagging, they can be sold for 30-40 yuan / kg. It can be seen that sorting and net bagging have significantly improved the economic benefits of fresh fruit commodities such as apricots and prunes.

[0004] However, the current net bagging and packaging of fresh fruits mostly relies on manual labor. The efficiency of manual net bagging and sorting of apricots is about 15-20 kg / hour; the efficiency of manual net bagging and sorting of prunes is about 4-6 kg / hour. During the peak season of fresh fruit harvest, the efficiency of manual bagging operations can easily restrict production and shipment, delaying the time for fruit to be put on the market.

[0005] In order to improve the efficiency of bagging, those skilled in the art have developed some semi-automatic fresh fruit packaging equipment or auxiliary tools, such as a fruit packaging conveyor assembly and a fruit packaging device disclosed in Chinese patent document CN116135709A. The fruit packaging device uses a fruit packaging conveyor assembly to keep the fruit stationary relative to the ground when bagging the fruit, so that the stretching assembly does not need to be stretched while bagging and moving synchronously with the conveyor belt, which can improve the accuracy of the stretching assembly when bagging the fruit, and facilitate long-distance transportation of the bagged fruit.

[0006] However, the above-mentioned fruit packaging device adopts intermittent packaging, elastic component positioning, and single-station work, with a long pause time, which leads to a prolonged beat, and puts forward high requirements on the power source and movement stability of the bag-holding mechanism. The tolerance for the size of the packaged fruit is also very low. During operation, the production beat is easily disrupted or even stopped, and the efficiency may even be lower than manual bagging. Summary of the invention

DETAILED DESCRIPTION

[0052] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] At present, the level of subsequent processing of fresh fruits after picking is relatively low. For example, the sorting and net bagging of fresh fruits basically rely entirely on manual work, which is labor-intensive, inefficient and has high production costs. A small part of fresh fruit sorting is carried out by traditional mechanical sorting, and the packaging operation is carried out by semi-automatic packaging equipment. In this way, due to the instability of the operation accuracy and the equipment itself, it is easy to damage the fruit. In order to accelerate the transformation of forestry and fruit production methods and improve the quality and efficiency of the industry, mechanization is urgently needed to support large-scale efficiency and promote standardized and high-quality development. Especially in the field of fresh fruit packaging, there is an urgent need to promote and apply intelligent technology and equipment to improve the efficiency of fruit net bagging while improving the commerciality of fruits and realizing processing value-added.

[0054] like Figure 1-8 As shown, a fresh fruit net bagging machine is proposed in the embodiment of the present invention, which aims to realize the automated net bagging operation of fresh fruit, solve the current technical problems of high labor intensity and high production cost of manual net bagging of fresh fruit, and improve the net bagging efficiency.

[0055] A fresh fruit mesh bag encapsulation machine proposed in an embodiment of the present invention uses a mesh bag clamping unit to convey a foaming mesh bag to an encapsulation station. The bag-supporting assembly in the bag-supporting unit supports the bag opening of the foaming mesh bag, and when the telescopic assembly drives the bag-supporting assembly to move from a first position to a second position, the foaming mesh bag is pulled and stretched into the encapsulation station, and the lifting assembly continues to deliver the fresh fruit into the foaming mesh bag, completing a encapsulation process. The fresh fruit mesh bag encapsulation machine realizes the automated operation of encapsulating fresh fruit with mesh bags, solves the current technical problems of high labor intensity and high production cost of manually encapsulating fresh fruit with mesh bags, and improves the efficiency of encapsulating fresh fruit with mesh bags.

[0056] Fresh fruit net bag packing machine]

[0057] like Figure 1 As shown, a fresh fruit net bag packaging machine includes a conveying unit 1, a lifting component 2, a net bag clamping unit 3, a bag supporting unit 4 and a cutting component 5.

[0058] like Figure 1 Combination Figure 2 As shown, the conveying unit 1 is used to convey fresh fruits. The conveying unit 1 defines a conveying plane 6. The fresh fruits are arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. A placement cavity 7 for supporting the fresh fruits is provided on the conveying plane 6. Figure 3 As shown, a mounting station 8 is arranged above the conveying plane 6 .

[0059] For example, the conveying unit 1 uses a conveyor chain device. The conveyor chain device is provided with a roller assembly for supporting fresh fruits. The conveyor chain device drives the roller assembly to rotate, and continuously transports the fresh fruits in the loading area to the bottom of the set station 8. A placement cavity 7 for supporting fresh fruits is formed between adjacent roller assemblies.

[0060] like Figure 1 As shown, the lifting component 2 is used to lift the fresh fruit in the placement cavity 7 out of the conveying plane 6. The lifting component 2 defines a lifting direction. For example, the conveying unit 1 conveys the fresh fruit in a horizontal plane, and the lifting direction of the lifting component 2 is arranged 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, so as to smoothly lift the fresh fruit out of the conveying plane 6 and prevent the fresh fruit from falling when the fresh fruit enters the set station 8.

[0061] like Figure 3As shown, the net bag clamping and conveying unit 3 is used to convey the foaming net bag to the suiting station 8, and make the bag mouth of the foaming net bag face the conveying plane 6. For example, the net bag clamping and conveying unit 3 is located above the suiting station 8. The net bag clamping and conveying unit 3 includes a storage rack 31 for storing the foaming net bag, and a feeding channel 415 is formed between the storage rack 31 and the suiting station 8. The feeding channel 415 is provided with a first clamping plate assembly 32, a second clamping plate assembly 33 and a clamping and conveying roller assembly 34. The clamping and conveying roller assembly 34 is located between the first clamping plate assembly 32 and the second clamping plate assembly. The clamping and conveying roller assembly 34 is used to form a conveying traction for the foaming net bag. The first clamping plate assembly 32 is located between the storage rack 31 and the clamping and conveying roller assembly 34.

[0062] During the process of conveying the foaming net bag by the net bag clamping and conveying unit 3, the first clamping plate assembly 32 and the second clamping plate assembly 33 both play the role of clamping or releasing the foaming net bag. When the net bag clamping and conveying unit 3 is in use, the second clamping plate assembly 33 clamps the foaming net bag, the first clamping plate assembly 32 releases the foaming net bag, and the clamping roller assembly 34 rotates to drive the foaming net bag to move in the direction of the second clamping plate assembly 33. Some of the foaming net bags in the storage rack 31 are conveyed out, and the foaming net bags are compressed between the second clamping plate assembly 33 and the clamping roller assembly 34. The length of the compressed foaming net bag is sufficient for packaging a single fresh fruit. Subsequently, the first clamping plate assembly 32 clamps the foaming net bag, and the second clamping plate assembly 33 releases the foaming net bag, so that the bag mouth of the foaming net bag faces the assembly station 8, which is convenient for the subsequent bag-holding and assembly operation.

[0063] like Figure 1 Combination Figure 3 As shown, the cutting assembly 5 is located between the set station 8 and the net bag clamping and conveying unit 3. The cutting assembly 5 is used to cut the foaming net bag.

[0064] like Figure 3 As shown, the bag-supporting unit 4 includes a bag-supporting assembly 41 for supporting the bag opening of the foaming net 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 is used to drive the bag-supporting assembly 41 to reciprocate between the first position and the second position.

[0065] The first position is located at the discharge port of the net bag clamping and conveying unit 3, and the second position is located between the set station 8 and the conveying plane 6. In the first position, the bag support component 41 supports the bag opening of the foaming net bag; when the telescopic component 42 drives the bag support component 41 to move from the first position to the second position, the foaming net bag is pulled and stretched into the set station 8, and the lifting component 2 lifts the fresh fruit out of the conveying plane 6 and delivers the fresh fruit into the foaming net bag; in the second position, the cutting component 5 cuts the foaming net bag along the radial direction of the foaming net bag.

[0066] When the fresh fruit net bag packaging machine proposed in the embodiment of the present invention is used, it is combined with Figure 5 As shown, the following steps are included:

[0067] Fresh fruits are transported, and batches of fresh fruits enter the placement cavity 7 in the conveying unit 1 one by one. The fresh fruits are arranged in a line in the conveying plane 6 along the conveying direction of the conveying unit 1. The conveying unit 1 implements step-by-step conveying of the fresh fruits, so that the fresh fruits stay under the packaging station 8. When the fresh fruits arrive under the packaging station 8, the conveying unit 1 suspends conveying and waits for the fresh fruits to be packaged.

[0068] The foaming mesh bag is transported. The mesh bag clamping and conveying unit 3 transports the foaming mesh bag to the assembly station 8 , and makes the bag opening of the foaming mesh bag face the conveying plane 6 .

[0069] To lift the fresh fruit, the conveying unit 1 stops conveying, and the lifting component 2 lifts the fresh fruit in the placement cavity 7 out of the conveying plane 6 and delivers the fresh fruit to the packaging station 8.

[0070] In bag-supporting packaging, the bag-supporting assembly 41 supports the bag opening of the foaming net bag. When the telescopic assembly 42 drives the bag-supporting assembly 41 to move from the first position to the second position, the foaming net bag is pulled and stretched into the set station 8, and the lifting assembly 2 continues to deliver the fresh fruit into the foaming net bag.

[0071] Cutting off the foaming net bag, when the telescopic component 42 drives the bag-holding component 41 to reach the second position, the bag-holding component 41 releases the bag opening of the foaming net bag, and the cutting component 5 cuts off the foaming net bag along the radial direction of the foaming net bag to complete the set of fresh fruits.

[0072] The lifting assembly 2 retracts to below the conveying plane 6 , and the conveying unit 1 continues to start to convey the next fresh fruit to below the packaging station 8 .

[0073] A fresh fruit net bag packaging machine proposed in the embodiment of the present invention utilizes the cooperation of the lifting component 2 and the conveying unit 1. The conveying unit 1 continuously transports the fresh fruit to the bottom of the packaging station 8, and the lifting component 2 delivers the fresh fruit arranged in a line along the conveying direction of the conveying unit 1 to the packaging station 8 one by one. The packaging line of the fresh fruit and the conveying direction of the conveying unit 1 only intersect once in the placement cavity 7, which greatly reduces the risk of interference between the packaging station and the conveying unit 1, is conducive to further improving the safety and stability of the equipment operation, optimizes the existing fresh fruit semi-automatic packaging equipment, avoids confusion in the packaging rhythm during the fresh fruit packaging process, and improves the packaging efficiency of the effect.

[0074] In order to further improve the collection efficiency of packaged fresh fruits, a collection box for collecting packaged fresh fruits is provided on one side of the conveying unit 1 , and the collection box corresponds to the assembly station 8 one by one.

[0075] Conveying unit]

[0076] like Fig.10 As shown, the conveying unit 1 uses a conveyor chain device. The conveyor chain device is provided with a roller assembly for supporting fresh fruits. The conveyor chain device drives the roller assembly to rotate, and continuously transports the fresh fruits in the loading area to the bottom of the set station 8. A support plate for placing fresh fruits is provided between adjacent roller assemblies.

[0077] like Fig.10 As shown, fresh fruit takes apple as an example. Under normal circumstances, the ends of the apples are in contact with the support plate, and the fruit body axis passing through the two ends of the apples points to the bag opening of the foam mesh bag. In this way, after the apples are packaged in the above posture, the foam mesh bag completes the packaging of the apples along the direction of the above fruit body axis. Since the ends of the foam mesh bag are all open, the ends of the apples are only contracted by the shrinkage elastic force of the foam mesh bag itself, and there is a lack of protection for the ends of the apples.

[0078] In order to further improve the protective effect of the foam mesh bag on fresh fruits, especially the packaging and protective effect of fresh fruits with fruit structures similar to apricots and prunes. Fig.11 As shown, when the conveying unit 1 continuously transports the fresh fruits located in the loading area to the bottom of the set station 8, the fresh fruits are arranged in a line in the conveying plane 6 along the conveying direction of the conveying unit 1. Under the action of gravity and friction, the fresh fruits will adaptively adjust their posture, so that the fruit body of the fresh fruit is in a lying state in the placement cavity, that is, the fruit body axis passing through the two ends of the fruit body points to the end of the roller assembly.

[0079] In this way, if Fig.11 As shown, taking prunes as an example, when the prunes are transported from the loading area to the bottom of the packaging station 8, the posture of the fruit body is adjusted to be in a flat state in the placement cavity. After the foaming mesh bag completes the packaging of the prunes, the side walls of the foaming mesh bag form effective protection for the ends of the prunes.

[0080] like Fig.12 As shown, the roller assembly is arranged linearly along the conveying direction of the conveying unit 1. The roller assembly includes a first tapered roller and a second tapered roller. The first tapered roller and the second tapered roller are arranged coaxially, and the tip of the first tapered roller and the tip of the second tapered roller are arranged facing each other, so that the linear support contour of the side walls of the first tapered roller and the second tapered roller for the fruit body is in the shape of an angle bracket. In this way, a diamond-shaped placement cavity structure is formed between adjacent roller assemblies, which facilitates the natural adjustment of the posture of the fruit body to a flat state during the conveying process, thereby facilitating the protection effect of the foaming mesh bag on the end of the fruit body after packaging.

[0081] Lifting Components]

[0082] like Figure 5 Combination Figure 6As 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 passing through the placement cavity 7 to lift the fresh fruit. The lifting cylinder 22 is arranged perpendicular to the conveying plane 6. The cylinder body of the lifting cylinder 22 is installed 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 dotted arrow shown in is the lifting direction of the lifting assembly 2.

[0083] When the lifting assembly 2 is in use, it cooperates with the conveying unit 1. When the conveying unit 1 conveys the fresh fruit to the bottom of the packaging station 8, the conveying unit 1 stops conveying, and the lifting cylinder 22 is actuated to drive the tray 23 to rise, lift the fresh fruit in the placement cavity 7 out of the conveying plane 6, and deliver the fresh fruit to the packaging station 8. After the fresh fruit is packaged in the packaging station 8, the lifting cylinder 22 is actuated to drive the tray 23 to retract to the bottom of the conveying plane 6, and the conveying unit 1 continues to start and deliver the next fresh fruit to the bottom of the packaging station 8.

[0084] Bag support assembly]

[0085] like Figure 7 As shown, the bag support assembly 41 includes a connecting frame 411, a parallel clamping cylinder 412 and a limit plate 414. The connecting frame 411 is provided with a connecting portion for connecting the telescopic assembly 42. A channel 415 for fresh fruit to pass through is provided on one side of the connecting frame 411. The cylinder body of the parallel clamping cylinder 412 is installed on the connecting frame 411. The clamp 413 of the parallel clamping cylinder 412 is located in the channel 415, and a pair of clamps 413 are opened in the channel 415 to expand the bag mouth of the foaming net bag. The limit plate 414 is arranged parallel to the clamp 413 and is located on the outside of the pair of clamps 413.

[0086] 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 portion of the connecting frame 411. The piston rod of the power cylinder 421 is connected to the mounting plate 424.

[0087] Cut off components]

[0088] like Figure 8As shown, the cutting assembly 5 includes a frame 51, a cutting wire 52 for electrically heating, and a cutting cylinder 53. The cutting cylinder 53 is arranged perpendicular to the lifting direction. The cutting cylinder 53 is used to drive the frame 51 to reciprocate along the radial direction of the foaming mesh bag. The frame 51 is connected to the piston rod of the cutting cylinder 53. The cutting wire 52 is installed on the frame 51.

[0089] In order to facilitate the packaged fresh fruits to leave the packaging station 8, a fruit pushing assembly for pushing the packaged fresh fruits out of the packaging station 8 is provided on the inner side of the frame 51. 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 installed on the frame 51. The push plate 54 is connected to the piston rod of the fruit pushing cylinder. For example, after the fresh fruits are packaged, a collection step is also included.

[0092] Step-by-step three-station collaborative packaging method]

[0093] When a fresh fruit net bagging machine proposed in the embodiment of the present invention is used, taking fresh prunes as an example, a step-by-step conveying three-station packaging method is used for bagging. Fig. 9 As shown, batches of fresh fruits enter the placement chamber 7 in the conveying unit 1 one by one, and the fresh fruits are arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. The conveying unit 1 implements step-by-step conveying of the fresh fruits, so that the fresh fruits stay below the packaging station 8. When the fresh fruits reach the bottom of the packaging station 8, the conveying unit 1 stops conveying and waits for the fresh fruits to be packaged.

[0094] like Fig. 9As shown, when the three-station fresh fruit net bag packaging machine is initially operated, the fresh fruit cannot be fully distributed in each placement cavity 7 on the conveying plane 6. When the first station is first performing the packaging operation, the other two subsequent stations are in an idle state. In order to quickly enter the state of three stations working together, the conveying unit 1 takes the first station as the reference when performing step-by-step conveying. When the first station completes the first fresh fruit packaging, the conveying unit 1 conveys three placement cavities 7 step by step and then pauses to ensure that the fresh fruit that has been released can quickly reach the subsequent second and third stations, so that the equipment quickly enters the state of three stations working together.

[0095] A fresh fruit net bag packing machine proposed in an embodiment of the present invention can realize operations such as feeding fresh fruits one by one, putting fresh fruits into net bags, and cutting net bags, and the operating speed can reach 40-50 pieces / minute. Taking fresh prunes as an example, the production efficiency technical indicators of the fresh fruit net bag packing machine are: 2000-3000 pieces / hour, and the supporting power is 1.5kw. The fresh fruits are sorted in sequence during the transportation of the conveying system and transported to the fruit receiving system. The net bag packing system, driven by the mobile cylinder, completes the clamping, supporting and conveying of the net bag to realize the operation of putting fresh fruits into net bags. Finally, the net bag is cut off by the net cutting system to achieve the purpose of accurate, efficient, lossless and intelligent bagging operation. The control system adopts PLC control, and detects the operating status of the conveying system and the net packing status through sensor detection technology, so as to monitor and control in real time through PLC to ensure the stable operation of the system. The project improves the imported technology and equipment to adapt to the intelligent net bagging operation of fresh fruits such as apricots and prunes, solves the current technical problems of high labor intensity and high production cost of manual net bagging of fresh fruits, and realizes precise, efficient and intelligent bagging operations.
