[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] The following describes in detail a fruit and vegetable box packing device 100 provided in an embodiment of the present application through a specific embodiment in conjunction with all the drawings in the specification.

[0040] Please refer to Figure 1 and Figure 2In one embodiment of the present invention, a fruit and vegetable boxing device 100 is disclosed, including a first guide rail 10, a first position variable distance module 20, a first drive assembly 30, and a gripping assembly 40. The first position variable distance module 20 includes a plurality of first variable distance units 22 sequentially arranged on the same first guide rail 10. The first variable distance units 22 include a first limiting member 24 and a second limiting member 26. The first limiting member 24 includes a first limiting end 242 and a second limiting end 244 sequentially arranged along the first guide rail 10. Of two adjacent first variable distance units 22 on the same first guide rail 10, the first limiting member 24 of one first variable distance unit 22 cooperates with the second limiting member 26 of the other first variable distance unit 22, and the second limiting member 26 is movable between the first limiting end 242 and the second limiting end 244 of the cooperating first limiting member 24.

[0041] The first drive assembly 30 is connected to the first guide rail 10. The first drive assembly 30 can drive the first distance variable unit 22 located on one side of the first position distance variable module 20 to move along the first guide rail 10; so that all the second limit members 26 on the same first guide rail 10 move to the corresponding first limit end 242, or so that all the second limit members 26 on the same first guide rail 10 move to the corresponding second limit end 244; the grabbing assembly 40 is connected to the first distance variable unit 22, and the grabbing assembly 40 is used to grab fruits and vegetables.

[0042] In some cases, the device for conveying fruits and vegetables includes multiple parallel bamboo sticks with inner grooves formed on the bamboo sticks. The inner grooves are used to partially insert the fruits and vegetables, so that the fruits and vegetables can be arranged in an array on the device for conveying fruits and vegetables. When the fruits and vegetables are conveyed to the fruit and vegetable boxing device 100, the fruits and vegetables are arranged in a regular pattern, that is, the spacing between adjacent fruits and vegetables is equal. However, fruits and vegetables also need to be arranged in an array in a packaging box, and the spacing between adjacent fruits and vegetables in the packaging box is different from the spacing between adjacent fruits and vegetables on the device for conveying fruits and vegetables.

[0043] Using the above structure, when fruits and vegetables are grabbed from a device for conveying fruits and vegetables and placed in a packaging box, the fruit and vegetable boxing device 100 first moves above the device for conveying fruits and vegetables. Subsequently, the first drive assembly 30 drives the first variable distance unit 22 located on one side of the first position variable distance module 20 to move along the first guide rail 10, causing all second stop members 26 on the same first guide rail 10 to move to the corresponding first stop end 242, thereby aligning the grabbing assembly 40 on each first variable distance unit 22 with the corresponding fruit and vegetable. The grabbing assembly 40 then grabs the corresponding fruit and vegetable.

[0044] Next, the fruit and vegetable packing device 100 moves to the packaging box. Then, the first drive assembly 30 drives the first variable distance unit 22 located on one side of the first position variable distance module 20 to move along the first guide rail 10, causing all second limit members 26 on the same first guide rail 10 to move to the corresponding second limit ends 244, thereby changing the spacing between two adjacent first variable distance units 22. This changes the spacing between two adjacent grabbing assemblies 40 to adapt to the spacing between two adjacent fruits and vegetables in the packaging box. Finally, the grabbing assembly 40 places the fruits and vegetables in the packaging box. Furthermore, the fruit and vegetable packing device 100 of the present invention can simultaneously grab multiple fruits and vegetables and place them in the packaging box, thereby improving the efficiency of fruit and vegetable packing.

[0045] Specifically, in this embodiment, the fruit and vegetable packing device 100 includes multiple first guide rails 10, each of which corresponds to a first position variable distance module 20; the first guide rail 10 is a bar-shaped structure, and the first variable distance unit 22 is connected to the first guide rail 10 through a clamping block, so that the first variable distance unit 22 can move on the first guide rail 10.

[0046] The first variable distance unit 22 is a rectangular block of metal, and the first limiter 24 and the second limiter 26 are both arranged on the same side of the first variable distance unit 22, and the first limiter 24 and the second limiter 26 are respectively located at the two ends of the first variable distance unit 22. The first limiter 24 can be a waist-shaped limiter groove, and the second limiter 26 is a protruding cylindrical limiter block; the length of the first limiter 24 is set to L1, the gap between two adjacent fruits and vegetables in the packaging box is L2, and the gap between two adjacent fruits and vegetables on the device for conveying fruits and vegetables is L3, so as to satisfy L3-L2=L1; so that on the fruit and vegetable boxing device 100, the gap between two adjacent fruits and vegetables can be adjusted from L3 to L2.

[0047] The first driving assembly 30 can be a cylinder, and the stroke of the cylinder is an integer multiple of the length of the first limit member 24, so that when the cylinder is extended, all the second limit members 26 on the same first guide rail 10 move to the corresponding first limit end 242; when the cylinder is retracted, all the second limit members 26 on the same first guide rail 10 move to the corresponding second limit end 244.

[0048] The grabbing assembly 40 is a suction cup, and the grabbing assembly 40 is connected to the corresponding first variable distance unit 22 through a cylinder, so that the grabbing assembly 40 can move vertically relative to the first variable distance unit 22.

[0049] In other embodiments, the first guide rail 10 can also be formed by two parallel sheet metal strips, and the first variable distance unit 22 is located between the two sheet metal strips, so that the first variable distance unit 22 can move on the first guide rail 10; the first variable distance unit 22 can also be other structures, such as a cylinder; the first limit member 24 and the second limit member 26 can also be other structures, such as a blind groove and a guide rod; the first drive assembly 30 can also be other structures, such as a stepper motor; the grasping assembly 40 can also be other structures, such as a robotic arm for grasping fruits and vegetables.

[0050] In some embodiments, the first limiting member 24 is a strip-shaped limiting groove, the second limiting member 26 is a limiting block, and the second limiting member 26 is placed inside the first limiting member 24 .

[0051] Through the above structure, the first limiting member 24 can guide the second limiting member 26 so that the second limiting member 26 can slide in the first limiting member 24; and the first limiting member 24 and the second limiting member 26 have simple structures and are easier to manufacture.

[0052] Specifically, in this embodiment, the first stopper 24 is linear, and the central axis of the first stopper 24 is parallel to the horizontal plane. The first stopper 24 is a through slot, and the second stopper 26 is disposed within the first stopper 24. In other embodiments, the first stopper 24 may also be a blind slot.

[0053] In some embodiments, the first limiting member 24 is a waist-shaped through groove, and the second limiting member 26 is a cylinder.

[0054] Through the above structure, the first limiting member 24 is a waist-shaped through groove, so that the first limiting end 242 and the second limiting end 244 can both adapt to the shape of the side surface of the second limiting member 26, and then when the second limiting member 26 is located at the first limiting end 242 or the second limiting end 244, the second limiting member 26 can be more stable.

[0055] Specifically, in this embodiment, each first position variable distance module 20 includes five first variable distance units 22, and the stroke of the first drive assembly 30 is equal to four times the length of the first limiter 24. In other embodiments, each first position variable distance module 20 may also include another number of first variable distance units 22, such as three or four.

[0056] In some embodiments, the first position distance changing module 20 also includes a fixed connection block 28, which is fixedly connected to the first guide rail 10; on the same first guide rail 10, the fixed connection block 28 is limitedly cooperated with the first limiting member 24 of the first distance changing unit 22 which is farthest from the first drive assembly 30.

[0057] Through the above structure, the fixed connection block 28 is fixedly connected to the first guide rail 10, so that when the driving component drives the first variable distance unit 22 to move, the fixed connection block 28 will not shake, and the entire first position variable distance module 20 can be more stable.

[0058] Specifically, in this embodiment, the fixed connection block 28 is fixedly connected to the first guide rail 10 by screws. In other embodiments, the fixed connection block 28 can also be fixedly connected to the first guide rail 10 by other means, such as welding or clamping.

[0059] It is understood that in the above-described embodiments, the structures of the first variable-pitch units 22 may be the same or different. Alternatively, the fixed connection block 28 may not be provided with the first stopper 24. In other words, the fixed connection block 28 may be provided with only the second stopper 26, which slidably engages with the adjacent first stopper 24.

[0060] Please refer to Figure 3 、 Figure 4 and Figure 5 In some embodiments, the fruit and vegetable packing device 100 further includes a second guide rail 50 , a second position variable distance module 60 and a second drive assembly 70 .

[0061] The second guide rail 50 is arranged in parallel with the first guide rail 10 , and the second driving assembly 70 is connected to one end of the second guide rail 50 .

[0062] The second position distance changing module 60 includes a plurality of second distance changing units 62 arranged in sequence on the same second guide rail 50, the second distance changing unit 62 includes a third limit member 64 and a fourth limit member 66, the third limit member 64 includes a third limit end 642 and a fourth limit end 644 arranged in sequence along the second guide rail 50; in two adjacent second distance changing units 62 on the same second guide rail 50, the third limit member 64 of one second distance changing unit 62 cooperates with the fourth limit member 66 of the other second distance changing unit 62, and the fourth limit member 66 can move between the third limit end 642 and the fourth limit end 644 of the cooperating third limit member 64.

[0063] The second guide rail 50 includes a fifth limit member 52, which cooperates with the third limit member 64 of the second variable distance unit 62 on the same second guide rail 50 that is away from the second drive assembly 70. The fifth limit member 52 can move between the third limit end 642 and the fourth limit end 644 of the cooperating third limit member 64.

[0064] The second drive assembly 70 can drive the second distance variable unit 62 located on one side of the second position distance variable module 60 to move along the second guide rail 50; so that the fifth limit member 52 and all the fourth limit members 66 on the same second guide rail 50 move to the corresponding third limit end 642, and the first distance variable unit 22 on the first guide rail 10 is aligned with the second distance variable unit 62 on the adjacent second guide rail 50; or so that the fifth limit member 52 and all the fourth limit members 66 on the same second guide rail 50 move to the corresponding fourth limit end 644, and the first distance variable unit 22 on the first guide rail 10 is staggered with the second distance variable unit 62 on the adjacent second guide rail 50.

[0065] Each second variable distance unit 62 is connected to a grab assembly 40 .

[0066] In some cases, fruits and vegetables are arranged in several rows within the packaging box, with adjacent rows of fruits and vegetables staggered; however, the fruits and vegetables are arranged in an array on the fruit and vegetable conveyor. With the above structure, the second guide rail 50 is arranged in parallel with the first guide rail 10; the fifth limiting member 52 and all fourth limiting members 66 on the same second guide rail 50 move to the corresponding third limiting end 642, and all second limiting members 26 on the same first guide rail 10 move to the corresponding first limiting end 242. The first variable distance unit 22 on the first guide rail 10 is aligned with the second variable distance unit 62 on the adjacent second guide rail 50, thereby enabling the fruit and vegetable boxing device 100 to grasp fruits and vegetables arranged in an array on the fruit and vegetable conveyor.

[0067] In addition, the fifth limit member 52 and all the fourth limit members 66 on the same second guide rail 50 move to the corresponding fourth limit end 644, and all the second limit members 26 on the same first guide rail 10 move to the corresponding second limit end 244, so that the first variable distance unit 22 on the first guide rail 10 is staggered with the second variable distance unit 62 on the adjacent second guide rail 50, and thus the fruit and vegetable boxing device 100 can place fruits and vegetables in the packaging box so that the fruits and vegetables are arranged in two staggered rows in the packaging box.

[0068] Specifically, in this embodiment, the structure of the second guide rail 50 is the same as that of the first guide rail 10, and the number of the first guide rails 10 and the second guide rails 50 are both multiple, all the first guide rails 10 and all the second guide rails 50 are parallel to each other, and a second guide rail 50 is provided between every two adjacent first guide rails 10.

[0069] The structure of the second variable distance unit 62 is the same as that of the first variable distance unit 22. The third limiting member 64 is a waist-shaped limiting groove. The fourth limiting member 66 and the fifth limiting member 52 are both limiting blocks embedded in the third limiting member 64. The length of the third limiting member 64 matched with the fourth limiting member 66 is equal to the length of the first limiting member 24. The length of the third limiting member 64 matched with the fifth limiting member 52 is equal to half the distance between two adjacent fruits and vegetables.

[0070] The second driving assembly 70 is a cylinder, and the stroke of the second driving assembly 70 is greater than the stroke of the first driving assembly 30 .

[0071] In other embodiments, the structure of the second guide rail 50 may be different from that of the first guide rail 10 ; the second driving assembly 70 may also be other structures, such as a stepping motor.

[0072] In some embodiments, the fruit and vegetable boxing device 100 further includes a mounting frame 80 , and the number of first guide rails 10 and second guide rails 50 are both multiple. The first guide rails 10 are connected to the mounting frame 80 , and the first guide rails 10 and the second guide rails 50 are arranged in parallel and alternately. Each first guide rail 10 corresponds to a first position variable distance module 20 and a first drive assembly 30 , and each second guide rail 50 corresponds to a second position variable distance module 60 and a second drive assembly 70 .

[0073] Through the above structure, the mounting frame 80 is used for installing the first guide rail 10 and the second guide rail 50, and the mounting frame 80 plays a positioning role for the first guide rail 10 and the second guide rail 50, so that the distance between the first guide rail 10 and the second guide rail 50 is adapted to the preset distance between two adjacent fruits and vegetables.

[0074] Specifically, in this embodiment, the mounting frame 80 is a hollow rectangular frame structure. In other embodiments, the mounting frame 80 can also be other structures, such as a block structure.

[0075] In some embodiments, the second guide rail 50 also includes a fixed mounting block 54, which is fixed relative to the second drive assembly 70, the second variable distance unit 62 is located between the second drive assembly 70 and the fixed mounting block 54, and the fifth limit member 52 is connected to the fixed mounting block 54.

[0076] With the above structure, when the second guide rail 50 and the first guide rail 10 have identical structures, the distance between the fixed mounting block 54 and the second drive assembly 70 is set to a constant value, so that when the piston rod of the second drive assembly 70 is extended, the fifth limit member 52 can move to the corresponding fourth limit end 644. Consequently, the second guide rail 50 and the first guide rail 10 can be produced simultaneously, simplifying the component types of the fruit and vegetable boxing device 100.

[0077] Specifically, in this embodiment, the fixed mounting block 54 is a block structure similar to a rectangular parallelepiped, and the fixed mounting block 54 is fixedly connected to the second guide rail 50 by screws. In other embodiments, the fixed mounting block 54 can also be other structures, such as a cylinder.

[0078] In some embodiments, the first drive assembly 30 and the second drive assembly 70 are both cylinders, and the stroke of the second drive assembly 70 is greater than the stroke of the first drive assembly 30 .

[0079] With the above structure, both the first drive assembly 30 and the second drive assembly 70 are cylinders, so the first drive assembly 30 can quickly drive the first variable pitch unit 22 to move, and the second drive assembly 70 can also quickly drive the second variable pitch unit 62 to move. In addition, the cost of the cylinder is lower.

[0080] Specifically, in this embodiment, the second drive assembly 70 is a composite cylinder, and one of the strokes of the second drive assembly 70 is the same as the stroke of the first drive assembly 30. In other embodiments, the second drive assembly 70 can also be a cylinder with a stroke greater than the stroke of the first drive assembly 30.

[0081] Please refer to Figure 6 In some embodiments, the gripping component 40 is a suction cup.

[0082] Through the above structure, when the grabbing assembly 40 moves vertically, the grabbing assembly 40 can absorb the surface of fruits and vegetables and grab the fruits and vegetables.

[0083] Specifically, the grabbing assembly 40 includes a plurality of flexible adsorption rings 42 , which are arranged in sequence from top to bottom to improve the adsorption force of the suction cup on the fruits and vegetables when the suction cup contacts the surface of the fruits and vegetables.

[0084] In some embodiments, there are multiple first guide rails 10 , all of which are arranged in parallel, and each first guide rail 10 corresponds to a first position variable distance module 20 and a first driving assembly 30 .

[0085] Through the above structure, multiple first drive assemblies 30 and multiple first position variable distance modules 20 work simultaneously, so that the fruit and vegetable packing device 100 can grab a larger number of fruits and vegetables at the same time, and can grab the fruits and vegetables layer by layer into the packaging box, further improving the packing efficiency of fruits and vegetables.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
