[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The purpose of this invention is to provide an integrated ripening and packaging device and method to solve the problems existing in the prior art. It can simultaneously ripen and package fruits on the same device, saving workload, improving work efficiency, and to a certain extent avoiding damage during transportation caused by excessive ripening of fruits before leaving the factory, thus optimizing the ripening and packaging effect.

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Example 1

[0052] like Figure 1-9 As shown, this embodiment provides an integrated ripening and packaging device 100, including a first ripening device 1, a first conveying device 2, a capping device 3, a second conveying device 4, and a second ripening device. The first ripening device 1 is disposed above the first conveying device 2, and the capping device 3 is disposed above the second conveying device 4. The first conveying device 2 is used to move the fruit 5 along a first conveying direction, and the second conveying device 4 is used to move the packaging box 6 along a second conveying direction. The height of the second conveying device 4 is lower than the height of the first conveying device 2, and the fruit 5 can fall from the first conveying device 2 into the packaging box 6 of the second conveying device 4. The first ripening device 1 is used to perform a first-stage ripening of the fruit 5 on the first conveying device 2, and the capping device 3 is used to cap the packaging box 6 containing the fruit 5 on the second conveying device 4. The second ripening device is used to fill the packaging box 6 with ripening gas.

[0053] By placing fruit 5 on the first conveyor device 2, the first conveyor device 2 moves fruit 5 along the first conveying direction; the first ripening device 1 ripens fruit 5 on the first conveyor belt; the packaging box 6 is placed on the second conveyor device 4, and the second conveyor device 4 moves packaging box 6 along the second conveying direction; the fruit 5, ripened by the first ripening device 1, falls from one end of the first conveyor device 2 into the packaging box 6 of the second conveyor device 4; the capping device 3 caps the packaging box 6 containing fruit 5 on the second conveyor device 4, and the second ripening device fills the packaging box 6 with ripening gas. The ripening and packaging integrated device 100 and ripening and packaging method provided in this embodiment can simultaneously ripen and package fruit 5 on the same device, saving workload and improving work efficiency; in addition to ripening before packaging, this invention also simultaneously ripens the fruit inside the packaging box 6 during transportation, organically unifying ripening, packaging, and transportation ripening, further improving work efficiency.

[0054] In a preferred embodiment, the end of the first conveying device 2 is positioned directly above the second conveying device 4, and the first conveying direction and the second conveying direction are parallel to each other. The length of the first conveying device 2 is less than the length of the second conveying device 4, and at least one end of the second conveying device 4 protrudes beyond the first conveying device 2. A cover device 3 is provided above the protruding end of the second conveying device 4.

[0055] In a more preferred embodiment, the first conveying device 2 is entirely positioned above the second conveying device 4, which helps to reduce the floor space occupied. The first conveying device 2 and the second conveying device 4 have the same conveying direction. In use, the fruit 5 is placed into the first conveying device 2 from the end away from the capping device 3 and moves along the first conveying direction. When it moves to the area below the first ripening device 1, the first ripening device 1 ripens the fruit 5. The packaging box 6 is placed into the second conveying device 4 from the end away from the capping device 3 and moves along the second conveying direction. By reasonably setting the placement time of the fruit 5 and the packaging box 6, and the conveying speed of the first conveying device 2 and the second conveying device 4, the fruit 5 falls from the end of the first conveying device 2 and lands exactly in the packaging box 6 on the second conveying device 4. When the packaging box 6 is filled with a certain amount of fruit 5, the packaging box 6 moves with the second conveying device 4 to the area below the capping device 3, where the capping device 3 installs the cap 8 on the packaging box 6, thus completing the ripening and packaging of the fruit 5.

[0056] The first ripening device 1 includes multiple ripening components. Each ripening component includes a first telescopic device 101, at least one light source 102, and at least one gas injection component 103. Each light source 102 and each gas injection component 103 is fixedly connected to each first telescopic device 101. Each first telescopic device 101 extends and retracts along a direction perpendicular to the length of the first conveying device 2, causing each light source 102 and each gas injection component 103 to rise and fall along the same direction perpendicular to the length of the first conveying device 2. The light source 102 can illuminate the fruit 5 on the first conveying device 2, and the gas injection component 103 can continuously spray a first concentration of ripening gas onto the fruit 5 on the first conveying device 2. Ripening is achieved through the combined action of the light source 102 and ripening gas, which is beneficial for improving the ripening effect and efficiency. The first telescopic device 101 can adjust the distance between the light source 102 and the gas injection component 103 and the fruit 5, making it flexible in application. It should be noted that the ripening component in this embodiment can not only use the light source 102 and ripening gas for ripening, but can also use other ripening methods such as spraying ripening agents onto the fruit 5 through a spraying device.

[0057] In a preferred embodiment, the first conveying device 2 includes a first conveying body 201 and a plurality of rolling components. Each rolling component includes at least one roller 202. Both ends of each roller 202 are rotatably connected to the first conveying body 201 around the center line of each roller 202. The center line of each roller 202 is perpendicular to the length direction of the first conveying body 201. The plurality of rollers 202 are distributed along the length direction of the first conveying body 201. Each roller 202 is used to connect to a first driving device, and the first driving device can drive each roller 202 to rotate along its own center line. The outer surface of the roller 202 is used to contact the outer surface of the fruit 5, and the roller 202 can drive the fruit 5 to move along the first conveying direction by rotating along its own center line. A first gap 203 is left between two adjacent rolling components. The roller 202 can drive the fruit 5 from each first gap 203 to the adjacent roller 202 by rotating along its own center line.

[0058] Each rolling assembly includes two rollers 202, with a second gap between the two rollers 202 of each rolling assembly. The first ripening device 1 also includes multiple ripening hoods, each ripening hood including a top plate 104 and two partitions 105. Each first telescopic device 101 is fixedly connected to the upper end of the top plate 104, and two partitions 105 are fixedly connected to both ends of each top plate 104. Each partition 105 extends away from the end of the first telescopic device 101. The length direction of the top plate 104 is parallel to the first conveying direction. The multiple partitions 105 are arranged along the length direction of the first telescopic device 101. The two first side baffles 2 of the first telescopic device 101... 04 protrudes upward from the rolling assembly. The first telescopic device 101 can drive each partition 105 to extend into each second gap. When each partition 105 extends into each second gap, two adjacent partitions 105 and two first side baffles 204 of the first conveying device 2 can form a ripening chamber 106. The ripening chamber 106 is a pressure-stabilizing space, and each partition 105 can restrict the movement of the fruit 5 along the first conveying direction. Each ripening chamber 106 is provided with at least one light source 102 and at least one gas injection assembly 103.

[0059] It should be noted that the small gaps between the two adjacent partitions 105 and the two first side baffles 204 of the first conveying device 2, and the leakage of ripening gas caused by these gaps, have a negligible impact on the ripening gas concentration during the ripening prediction process. Each light source 102 and each gas injection assembly 103 is fixedly connected to the lower end of the top plate 104 and / or the partitions 105.

[0060] In a more preferred embodiment, the size of the first gap 203 is larger than the size of the second gap. When the fruit 5 is placed into the first conveying device 2, it moves along the first conveying direction under the drive of the rollers 202. Since the gaps between the multiple rollers 202 of each rolling component are small, the fruit 5 will pass through the multiple rollers 202 of each rolling component relatively quickly. The first gap 203 allows the fruit 5 to stay for a certain period of time. Therefore, after being conveyed by the first conveyor belt, most or all of the fruit 5 will stay in the first gap 203, which facilitates the targeted setting of ripening components for regional ripening and improves the ripening effect. The first conveying body 201 includes a support member for the rolling component, and the rolling component is rotatably connected to the support member. The connection method between the first driving device and the rolling component is prior art and will not be described in detail here.

[0061] In a preferred embodiment, the side baffle of the first conveying device 2 is provided with multiple infrared sensors 9, and at least one infrared sensor 9 is provided at the corresponding position of each first gap 203 on the first conveying device 2. Each infrared sensor 9 is communicatively connected to the control device and is used to detect whether there is fruit 5 in each first gap 203. When the infrared sensor 9 detects that fruit 5 has entered the last first gap 203 on the first conveying device 2, the control device controls the first conveying device 2 to stop. At this time, there may be some first gaps 203 without fruit 5. The control device can know which first gaps 203 have fruit through the infrared sensors 9, and controls the first telescopic device 101 above these first gaps 203 to extend downward, so that the first ripening device 1 covers the fruit to be ripened, and controls the corresponding light source 102 to turn on and the corresponding gas injection component 103 to spray air. At the same time, the first conveying device 2 is turned on. Under the action of the friction between the fruit 5 and the corresponding roller 202 and the limiting action of the partition 105, the fruit 5 rotates on the first conveying device 2, thereby improving the uniformity of ripening.

[0062] The second ripening device includes an air inlet pipe 7, and a cover-fastening device 3 includes a cover-fastening assembly and a support device 301. The cover-fastening assembly includes a connecting plate, a second telescopic device 302, and a suction cup 303. The second telescopic device 302 is fixedly connected to the support device 301, and its output end is fixedly connected to the connecting plate. One end of the suction cup 303 is fixedly connected to the connecting plate, and the other end of the suction cup 303 extends away from the second telescopic device 302. The air inlet pipe 7 can extend from the connecting plate near the second telescopic device 301. One side of the 2 extends through the connecting plate to the other side, and the air outlet of the air inlet pipe 7 is located on the side of the connecting plate away from the second telescopic device 302. The second telescopic device 302 can drive the suction cup 303 to rise and fall along a direction perpendicular to the second conveying direction. The suction cup 303 can adsorb and release the cover 8. The cover 8 is provided with a one-way air inlet valve 801. When the suction cup 303 adsorbs the cover 8, the air outlet of the air inlet pipe 7 can be connected to the one-way air inlet valve 801 on the cover 8. The air inlet of the air inlet pipe 7 is used to connect with the air supply device. Specifically, when the plane of the suction cup 303 is parallel to the horizontal plane, the suction cup 303 can adsorb the cover 8 well, and at this time, the air inlet pipe 7 on the suction cup 303 can be exactly opposite to the air inlet of the one-way air inlet valve 801 on the cover 8, ensuring that while the suction cup 303 adsorbs one cover 8, the air inlet pipe 7 on the suction cup 303 can be connected to the one-way air inlet valve 801 on the cover 8. In use, a lid 8 is adsorbed by the suction cup 303, and the air inlet pipe 7 on the suction cup 303 is connected to the one-way air inlet valve 801 on the lid 8. When the packaging box 6 moves to below the second telescopic device 302, the second conveying device 4 is stopped, and the second telescopic device 302 drives the suction cup 303 to move downward, so that the lid 8 on the suction cup 303 is fastened to the opening of the packaging box 6. After the lid is fastened, ripening gas is introduced into the packaging box 6 through the air inlet pipe 7 to continue ripening the fruit 5 during transportation and storage. The suction cup 303 is released, and the second telescopic device 302 is controlled to move upward, and the second conveying device 4 is controlled to open, so that the packaging box 6 after the lid is fastened moves away from the fastening position, and the next packaging box 6 to be fastened moves to the fastening position. Meanwhile, by debugging the equipment and reasonably setting the conveying speed, start and stop times of the first conveying device 2 and the second conveying device 4, when the second conveying device 4 stops to close the lid, there is a packaging box 6 at the end of the first conveying device 2 to receive the fruit 5 falling from the end of the first conveying device 2; when the lid is closed and the second conveying device 4 is opened, the packaging box 6 can hold a specified amount of fruit 5, thus improving the automation level of fruit ripening and packaging.

[0063] In a preferred embodiment, the cover assembly further includes a rotating shaft and a cover body 8 storage device. There are multiple cover assemblies, and each rotating shaft is rotatably connected to the support device 301 around the axis of the rotating shaft. Each second telescopic device 302 is fixedly connected to the rotating shaft. The cover body 8 storage device is disposed above the second telescopic device 302. The cover body 8 storage device includes a storage rack and a limiting plate. The upper part of the support plate of the storage rack is used to stack the cover body 8. The support plate of the storage rack has a through hole, the size of which is larger than the size of the cover body 8. The through hole is disposed opposite to the second telescopic device 302. The limiting plate is connected to the lower part of the support plate. The limiting plate can extend and retract along the lower surface of the support plate to limit the cover body 8. When the suction cup 303 is not performing a cap removal operation, the limiting plate extends below the through hole and supports the cap 8 to prevent it from falling off. When the suction cup 303 performs a cap removal operation, the rotating shaft rotates, causing the suction cup 303 to face the through hole. The suction cup 303 then adsorbs one cap 8. At this time, the limiting plate retracts until it is no longer in contact with the cap 8. The suction cup 303 removes one cap 8 from the through hole. At the same time, the limiting plate extends to continue to limit and support other caps 8. After the suction cup 303 has adsorbed all the caps 8, the rotating shaft rotates, so that the suction cup 303 is aligned with the opening of the packaging box 6. The second telescopic device 302 extends downward to complete the cap closing.

The first limiting device 10 and the surface away from the second conveying direction are the limiting surfaces. The limiting surfaces can contact the outer wall of the packaging box 6 and restrict the movement of the packaging box 6 along the second conveying direction, so that the packaging box 6 stops below the second telescopic device 302 and does not continue to move along the second conveying direction. Each of the two second side baffles of the second conveying device 4 is provided with a second limiting device 11. One side of each second limiting device 11 is fixedly connected to one of the second side baffles of the second conveying device 4, and the other side of each second limiting device 11 extends towards the center of the width direction of the second conveying device 4. Each second limiting device 11 is located below the capping device 3. The two second limiting devices 11 on both sides of each conveyor belt body can respectively contact the two outer walls of the packaging box 6 on each conveyor belt body perpendicular to the second conveying direction, thereby restricting the movement of the packaging box 6 perpendicular to the second conveying direction, so as to achieve the guiding effect on the fruit 5. Through the limiting effect of the first limiting device 10 and the second limiting device 11, when the second telescopic device 302 drives the suction cup 303 to move downward to cap, the cap 8 on the suction cup 303 can correspond exactly to the opening of the packaging box 6, thereby realizing the capping operation.

The two third limiting devices 12 on both sides of each first conveying device 2 can respectively contact the two outer walls of the fruit 5 on each first conveying device 2 perpendicular to the first conveying direction to restrict the movement of the fruit 5 along the perpendicular to the first conveying direction, so as to achieve the guiding effect on the fruit 5.

[0069] In a preferred embodiment, the distance between the ends of the two third limiting devices 12 at the end of the first conveying device 2 is less than or equal to the size of the opening of the packaging box 6 along the width direction of the first conveying device 2, so as to better ensure that the fruit 5 will not fall outside the packaging box 6.

That is, the distance between the guide surface of the second limiting device 11 and the surface of the second side baffle near the center surface of the width direction of the second conveying device 4 gradually increases along the second conveying direction. The surface of each second limiting device 11 near the middle surface of the width direction of the second conveying device 4 is the limiting surface.

[0079] Example 2

[0080] like Figure 10 As shown, this embodiment provides a ripening and packaging method based on the integrated ripening and packaging device 100 in Embodiment 1, comprising the following steps:

[0081] Fruit 5 is placed on the first conveyor device 2, and the first conveyor device 2 moves the fruit 5 along the first conveying direction; the first ripening device 1 performs the first stage ripening of the fruit 5 on the first conveyor belt; the packaging box 6 is placed on the second conveyor device 4, and the second conveyor device 4 moves the packaging box 6 along the second conveying direction; the fruit 5, which has been ripened by the first ripening device 1, falls from one end of the first conveyor device 2 into the packaging box 6 of the second conveyor device 4; the capping device 3 caps the packaging box 6 containing the fruit 5 on the second conveyor device 4, and ripening gas is injected into the packaging box 6 to continue ripening the fruit during transportation.

[0082] In a preferred embodiment, the ripening and packaging integrated device 100 also includes a maturity detection device, which includes an optical characteristic-based maturity detection device 17, a color-based maturity detection device 18, and an odor-based maturity detection device 19. The optical characteristic-based maturity detection device 17, the color-based maturity detection device 18, and the odor-based maturity detection device 19 can all be connected to a control device, and all three devices can detect the maturity of the fruit 5.

[0083] Before ripening, the fruit 5 on the first conveying device 2 is detected by the ripeness detection device 17 based on optical characteristics and the first ripeness of the fruit 5 is obtained. The fruit 5 on the first conveying device 2 is detected by the ripeness detection device 18 based on color and the second ripeness of the fruit 5 is obtained. The fruit 5 on the first conveying device 2 is detected by the ripeness detection device 19 based on odor and the third ripeness of the fruit 5 is obtained. The control device receives the information of the first ripeness, the second ripeness and the third ripeness and obtains the overall ripeness of the fruit 5 through formulas (1)-(5).

[0084]

[0085]

[0086]

[0087] M = x1M l +x2M c +x3M S (4)

[0088] x1 + x2 + x3 = 1 (5)

[0089] Among them, M l denoted as the first degree of maturity of fruit 5, k represents the spectral wavelength maturity information of fruit 5 when soluble solids are used as the evaluation index, x represents the spectral wavelength maturity information of fruit 5 when chlorophyll is used as the evaluation index, n represents the number of spectral bands, and s represents the surface area of ​​fruit 5 receiving light.

[0090] M c For fruit at level 5, the second stage of ripeness, y p a is the area representing the ripe color within the image of fruit 5 acquired by the color-based ripeness detection device 18. p For y p In the proportion of the total mature area, s represents the surface area of ​​the fruit that receives light.

[0091] M SThe third ripeness of fruit 5 is represented by μ, where μ is the adjustment factor of the odor sensor in the odor-based ripeness detection device 19, and q is the third ripeness level. -w The odor-based maturity detection device 19 uses the current value fed back based on the mature odor, where w is the feedback current coefficient.

[0092] M represents the overall maturity of fruit 5, and x1, x2, and x3 represent the percentages of the first, second, and third maturity levels, respectively. Preferably, x1, x2, and x3 are 0.4, 0.4, and 0.2, respectively.

[0093] The ripeness of fruit 5 is detected by a combination of an optical ripeness detection device 17, a color-based ripeness detection device 18, and an odor-based ripeness detection device 19, and the data is processed by a control device, thus improving the accuracy of the ripeness detection of fruit 5. The initial ripeness of fruit 5 is obtained through the ripeness detection devices before artificial ripening, providing a basis for formulating a ripening plan for fruit 5.

[0094] In a preferred embodiment, the first ripening device 1 includes multiple ripening components. Each ripening component includes a first telescopic device 101, a light source 102, a gas injection component 103, and a ripening hood. Each ripening hood includes a top plate 104 and multiple partitions 105. Each first telescopic device 101 is fixedly connected to the upper end of the top plate 104. Each light source 102 and each gas injection component 103 are fixedly connected to the lower end of the top plate 104 and / or to the partitions 105. Each partition 105 is fixedly connected to the top plate 104 and extends away from the end of the first telescopic device 101. Extended, multiple partitions 105 are arranged along the length of the top plate 104. The length of the top plate 104 is parallel to the first conveying direction. When the first telescopic device 101 drives each partition 105 to descend between the two side baffles of the first conveying device, two adjacent partitions 105 and the two side baffles of the first conveying device 2 can form a ripening chamber 106. Each ripening chamber 106 is provided with at least one ripening component. The ripening chamber 106 is arranged opposite to the first gap 203. Each partition 105 can restrict the movement of the fruit 5 along the first conveying direction.

[0095] The ripening and packaging integrated device 100 also includes a control device. Each light source 102 and each gas injection component 103 are connected to the control device. The control device can adjust at least one of the following: the surface area of ​​the fruit 5 receiving the light source, the concentration of the first concentration ripening gas injected by the gas injection component 103, and the ripening time.

[0096] Before ripening, the surface area of ​​the fruit 5 receiving the light source, the concentration of the first concentration ripening gas sprayed by the gas spray component 103, or the ripening time required for different ripening levels during the first stage of ripening are obtained by using the control device and formula (6).

[0097]

[0098] Among them, R n1 R represents the initial maturity level. n Let n be the ripeness level of fruit 5 after the first stage of ripening, t be the ripening time, s be the surface area of ​​fruit 5 receiving light, T2 be the set ripening temperature, T1 be the initial temperature of ripening chamber 106, Q be the concentration index of the first concentration ripening gas injected by gas injection component 103, m be the mass of fruit 5, V be the volume of air in ripening chamber 106, and δ be the ripening adjustment coefficient, δ∈(-1,1).

[0099] In a preferred embodiment, the control device can control the surface area of ​​the fruit 5 receiving the light source by controlling the rotation angle of the roller 202. For example, if the roller 202 does not rotate during the ripening process, the surface area of ​​the fruit 5 receiving the light source is the portion facing the light source 102, i.e., the surface area receiving the light source is relatively small. If the roller 202 rotates and the rotation angle is less than 360°, the rotation angle of the fruit 5 is less than 360°. If the roller rotation angle is greater than 360° and it continues to rotate, the surface area of ​​the fruit 5 receiving the light source can be made close to the entire outer surface. It should be noted that the adjustment of the surface area of ​​the fruit 5 receiving the light source in this invention is a relatively coarse adjustment. In actual use, to ensure the uniformity of ripening, the roller 202 will continue to roll, and the area of ​​the entire outer surface of the fruit 5 is used as the surface area receiving the light source in the calculation.

[0100] In a preferred embodiment, the gas injection assembly 103 can be connected to multiple storage components storing different concentration levels, and each storage component is provided with a valve between itself and the gas injection assembly 103. Each valve is connected to a control device, and the control device switches the gas concentration by controlling the opening and closing of the valves.

[0101] As a preferred implementation method, a ripening plan is pre-defined based on the maturity requirements of the target order, delivery distance and time, and the initial maturity of the fruit before ripening. The ripening level after the first stage of ripening and the ripening grade after the first stage of ripening are determined in advance. The concentration level of the ripening gas and the temperature level during ripening are also pre-set. The entire outer surface area of ​​fruit 5 is used as the surface area receiving the light source, and the ripening time is calculated using Formula 1. By controlling the ripening time, the maturity level of fruit 5 after the first stage of ripening reaches the design requirements. This improves the ripening effect and achieves high-quality sales.

[0102] In a preferred embodiment, the second ripening device includes an air inlet pipe 7 and a cover 8 having a one-way air inlet valve 801. The one-way air inlet valve 801 of the air inlet pipe 7 is used to communicate with the air supply device, and the air outlet of the air inlet pipe 7 can communicate with the cover 8 and introduce a second concentration of ripening gas into the packaging box 6.

[0103] S3. The concentration of the second-concentration ripening gas required for different maturity levels during the second-stage ripening process is obtained by using the control device and formula (7); the second-concentration ripening gas is introduced into the packaging box 6 through the air inlet pipe 7 for the second-stage ripening.

[0104]

[0105] Among them, R N Let n be the ripeness level of fruit 5 after the second stage of ripening, t be the ripening time, Tp be the average temperature during the ripening process, T1 be the initial temperature inside the packaging box 6, Q be the concentration index of the second concentration ripening gas, m be the mass of fruit 5, V be the volume of air inside the packaging box 6, and δ be the ripening adjustment coefficient, where δ∈(-1,1).

[0106] Based on the ripening level required for the second stage of ripening, the concentration of the second-concentration ripening gas is further obtained by the control device through Formula 2, so as to achieve high-quality sales according to the ripening requirements of the order information.

[0107] As a preferred embodiment, the maturity detection device can continuously detect the maturity of fruit 5 and automatically feed the maturity information back to the control device, realizing closed-loop uniform ripening and predictive control under optical characteristics and fruit color error correction. When the maturity detected by the maturity detection device reaches the ripening level required for the first stage of ripening, the control device controls the first ripening device 1 to stop ripening.

[0108] The ripening and packaging method provided in this embodiment can freely adjust the ripeness and flesh texture according to the ripeness requirements such as sales time, distance, orders and consumer demand. The entire ripeness grading and packaging process is automatically controlled to accelerate ripening, which improves the level of intelligent ripening control, facilitates high-quality sales according to demand, and provides consumers with high-quality fruits with uniform appearance and color.

[0109] To illustrate the effects of the present invention, such as Figure 11 As shown, a batch of fruits at the same maturity level and with small individual differences underwent traditional unripened packaging, traditional ripened packaging, and the ripening packaging of this invention. The unripened packaging method involved manual packaging, while the traditional ripening packaging method involved ripening a large batch of fruits piled together and then manually packaging them. The same quantity of fruit was used in all three methods. The comparative analysis results of the three ripening packaging methods are as follows:

[0110] Ripening effect: After ripening for the same period of time using the ripening packaging methods of the present invention (without ripening packaging, traditional ripening packaging, and the ripening packaging of the present invention), the ripening uniformity of the fruit after ripening using the ripening packaging of the present invention is higher.

[0111] Ripening efficiency: Among the ripening methods of fruit without ripening packaging, traditional ripening packaging, and the ripening packaging of the present invention, the ripening packaging of the present invention requires the shortest time for all fruits to reach the set ripeness level. The next fastest method is the traditional ripening packaging method, while the ripening packaging without ripening packaging takes the longest. In other words, the ripening efficiency is the highest when using the ripening packaging of the present invention.

[0112] Predicted results: When fruits are ripened according to the set ripening plan using the ripening packaging method of this invention, most fruits can achieve the set ripening effect, that is, the predicted effect is the best. The predicted effect of ripening using the traditional ripening packaging method is poor, and the predicted effect of ripening without ripening packaging is the worst.

[0113] Production time: This includes ripening time and packaging time. The production time is shortest when using the ripening and packaging method of this invention, followed by the method without ripening packaging. The longest production time is when using the traditional ripening and packaging method.

[0114] To ensure the normal operation of the integrated ripening and packaging unit, a user-friendly remote operation method was designed to rehearse and dynamically demonstrate the ripening and packaging production process, allowing for intuitive pre-control and rehearsal of the integrated ripening and packaging unit. This primarily includes a multi-device collaborative manufacturing system, a device that utilizes advanced augmented reality (AR) and digital twin (DT) technologies for manual cyclical control. In this system, the integrated ripening and packaging unit is first mapped onto a virtual device and visualized through AR glasses. Simultaneously, a communication mechanism between the virtual and real devices was designed and implemented to synchronize their states. By controlling the interaction between the virtual and real devices, the normal operation of the integrated ripening and packaging unit is achieved.

[0115] The working methods or steps of a multi-device collaborative manufacturing system include:

[0116] 1) Create a three-dimensional digital model of the actual integrated ripening and packaging device and its working environment, and set it in a virtual environment to complete the construction of the equipment and scene.

[0117] 2) To meet the requirements for ripening and packaging, preliminary drills were conducted on virtual equipment, while the actual equipment operating status and ripening conditions (ripening gas release, temperature, etc.) could be adjusted.

[0118] 3) Establish a communication and linkage mechanism between virtual devices and real devices, so that real devices can be remotely controlled and monitored by adjusting virtual devices.

[0119] 4) After the virtual state test meets the requirements, the real device is then tested. At the same time, the virtual device runs synchronously while the real device is running.

[0120] In summary, this invention outperforms traditional batch ripening in terms of ripening effect, ripening efficiency, and predictive effect, meaning the ripening quality is superior to traditional batch ripening, and it overcomes the problem of inconsistent ripening speeds for individual fruits. It also integrates ripening and packaging processes and enables automated fruit packaging, resulting in shorter delivery times compared to unripened packaging and traditional ripening methods.

[0121] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
