Technical Field

[0001] The utility model relates to the field of fruit and vegetable sorting equipment, in particular to a fruit cup return device and sorting equipment. Background Art

[0002] There are two types of devices for straightening the fruit cup and rotating the fruit cup wheel in the prior art: one is a separate structure, which first performs guidance through a return structure at the front end, and then adds a friction belt at the driving sprocket position to help the fruit cup wheel rotate; the other integrates the return structure and the rotating mechanism into one device to guide and assist the rotation of the fruit cup.

[0003] The inventors have found that the function of the separate structure device consists of two parts: the fruit cup rotating device and the fruit cup return device. First, the two parts need to be installed separately, and the two positions need to be adjusted separately after installation, which requires a large space to be installed on the machine. Secondly, after the fixed arc plate has been used for a long time to assist in cup turning, the surface will be obviously worn after a period of use; and the fixed arc plate has many fixed positions and a small disassembly and assembly area, so it is difficult, complicated and time-consuming to replace the worn parts of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] After the sorting of fruits and vegetables is completed, when the empty fruit cups are transported to the tail assembly frame 011 of the sorting equipment, the fruit cup rotating device and the fruit cup returning device arranged on the tail assembly frame respectively rotate and return the fruit cups. In the prior art, the fruit cup rotating device and the fruit cup returning device need to be installed separately, and the two positions need to be adjusted separately after installation, and installation on the machine requires a large space. Secondly, after the fixed arc plate has been used for a long time to assist in cup turning, the surface has obvious wear after a period of use; and the fixed arc plate has many fixed positions and a small disassembly and assembly area, and it is difficult, complicated and time-consuming to replace the worn parts of the device. Finally, the structure for straightening the fruit cup needs to have good symmetry during installation, otherwise it is easy to cause the fruit cup to tip over again after passing through, which requires a large workload.

[0040] The sorting device 010 proposed in this embodiment is used to sort fruits and vegetables, so as to classify the fruits and vegetables according to the set classification method, thereby completing the classification of different types of fruits and vegetables in the same batch; at the same time, it has the functions of cleaning, rotating and returning the fruit cup 100.

[0041] Please refer to Figure 1 The present embodiment provides a sorting device 010 including a tail assembly frame 011 and a fruit cup return device 012 ; the fruit cup return device 012 is disposed on the tail assembly frame 011 .

[0042] In this embodiment, the tail assembly frame 011 is arranged at the tail of the sorting equipment 010, a fixed assembly frame 200 is arranged on the tail assembly frame 011, and two fruit cup return devices 012 are arranged on the fixed assembly frame 200. The two fruit cup return devices 012 are used to return the fruit cup 100 and rotate and clean the fruit cup 100.

[0043] Please refer to Figure 6 The fruit cup return device 012 proposed in this embodiment includes a conveying structure 300, a return structure 400 and an arc plate structure 500; the conveying structure 300 is used to convey the fruit cup 100; the return structures 400 are arranged on both sides of the conveying structure 300, the return structures 400 rotate with the conveying structure 300 and are used to return the fruit cup 100 during the conveying process; the arc plate structure 500 is sandwiched between the conveying structure 300 and the return structures 400 on both sides, and a friction surface 510 is arranged on the arc plate structure 500, the friction surface 510 is lower than the outer edge of the return structure 400 and the friction surface 510 is arranged along the conveying direction 350 of the conveying structure 300, and the friction surface 510 is used to rotate the fruit cup 100 during the conveying process.

[0044] It can be understood that by providing the synchronously rotating conveying structure 300 and the return structure 400, when the fruit cup 100 is conveyed to the return structure 400, the return structure 400 can contact the fruit cup 100 and give an upward force to the fruit cup 100 to return the fruit cup 100. At the same time, when the fruit cup 100 contacts the return structure 400 and returns to the original position, a large area of ​​friction and scratching will not occur at the same position of the return structure 400, thereby reducing the wear of the return structure 400 and increasing the service life of the return structure 400. In addition, by providing the arc plate structure 500, the fruit cup 100 after returning to the original position contacts the return structure 400 and contacts the friction surface 510 of the arc plate structure 500 under the drive of the conveying structure 300, so that the fruit cup 100 can rotate, thereby avoiding the fruit cup 100 from being not cleaned properly in the subsequent process.

[0045] Please refer to Figure 2 In this embodiment, the fruit cup returning device 012 includes a fruit cup 100 .

[0046] Optionally, the fruit cup 100 includes a body 110 and a first supporting portion 111 and a second supporting portion 112 disposed on the body 110 .

[0047] Specifically, the main body 110 is fixed to the conveying structure 300; the main body 110 is provided with a symmetrically arranged first limit portion 120 and a second limit portion 130, and the first limit portion 120 and the second limit portion 130 are respectively supported by two guide surfaces 411; wherein the first limit portion 120 is rotatably connected to the first supporting portion 111, and the second limit portion 130 is rotatably connected to the second supporting portion 112.

[0048] When the conveying structure 300 is a sprocket shaft 330 set, the main body 110 is fixed to the chain 310 of the sprocket shaft 330 set; and a plurality of fruit cups 100 can be fixed on the chain 310 at the same time.

[0049] Specifically, the first supporting portion 111 and the second supporting portion 112 are symmetrically arranged; and the symmetrically arranged first limiting portion 120 and the second limiting portion 130 are both provided with an inwardly concave structure, which is used to support fruits and vegetables in cooperation. The first supporting portion 111 is rotatably connected to the first limiting portion 120, and the second supporting portion 112 is rotatably connected to the second limiting portion 130.

[0050] It is understandable that when the first supporting portion 111 and the second supporting portion 112 are in contact with the guide surfaces 411 of the return structures 400 on both sides, the first supporting portion 111 and the second supporting portion 112 are located on the same horizontal line, thereby achieving the return of the fruit cup 100.

[0051] In this embodiment, the fruit cup restoring device 012 includes a fixed assembly frame 200 .

[0052] The fixed assembly frame 200 is a combined bracket structure and is fixed on the tail assembly frame 011; the cleaning brush structure 600 and the conveying structure 300 are arranged on the fixed assembly frame 200; the arc plate structure 500 is detachably connected to the fixed assembly frame 200. The structure is simple, with fewer fixed positions and convenient disassembly; it is more convenient and quick to replace components, reducing the workload of replacing components.

[0053] Please refer to Figure 3 and Figure 6 In this embodiment, the fruit cup returning device 012 includes a conveying structure 300 , and the conveying structure 300 includes an input end and an output end arranged along a conveying direction 350 .

[0054] In this embodiment, the transmission structure 300 is a sprocket shaft 330 set, wherein the sprocket shaft 330 set includes a chain 310, a sprocket body 320, a sprocket shaft 330 and a bearing seat 340. At least two bearing seats 340 are disposed on the fixed assembly frame 200.

[0055] The sprocket body 320 is a wheel with cog-type sprocket teeth for meshing with the chain 310; the two sides of the sprocket body 320 are respectively fixedly connected to the return disk 410, so that the return disk 410 rotates together with the sprocket body 320. The sprocket shaft 330 penetrates the sprocket body 320 and is spline-connected to the sprocket body 320, and the two ends of the sprocket shaft 330 are sleeved with two bearing seats 340, and are respectively rotatably connected to at least two bearing seats 340 through bearings.

[0056] The chain 310 is sleeved on the sprocket body 320 and meshedly connected with the sprocket body 320 , and a plurality of fruit cups 100 are fixed on the chain 310 .

[0057] It can be understood that when the fruit cup 100 moves to the return disk 410 driven by the chain 310, the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 are in contact with the guide surfaces 411 of the return disk 410 on both sides respectively; during the synchronous rotation of the return disk 410 and the sprocket body 320 and the synchronous movement of the chain 310 and the sprocket body 320, the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 are given an upward force by the guide surface 411 of the return disk 410, so that the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 are located on the same horizontal line, that is, the fruit cup 100 is returned to the center.

[0058] Please refer to Figure 3 In this embodiment, both sides of the sprocket body 320 are transmission-connected with a return structure 400 .

[0059] Optionally, the return structure 400 includes a return disc 410; the return disc 410 is a circular disc structure, and the outer edge of the return disc 410 is a perfect circular arc surface; wherein, a guide surface 411 is provided on the outer edge of the return disc 410, and the guide surface 411 is used to support and return the guide surface 411 of the fruit cup 100.

[0060] In this embodiment, a limiting hole (not shown) is provided at the center of the return disk 410, and the two return disks 410 are fixed to the two sides of the sprocket body 320 through the limiting holes. Of course, in other embodiments, the two return disks 410 can also be fixed on the sprocket shaft 330 through the limiting holes and arranged on the two sides of the sprocket body 320.

[0061] It is understandable that, since the return disk 410 rotates together with the conveying structure 300, the fruit cup 100 will not have a large area of ​​friction and scratches at the same position of the return disk 410 when it contacts the return disk 410 and returns to the center, thereby reducing the wear of the return disk 410 and increasing the service life of the return disk 410.

[0062] It is worth mentioning that two groups of conveying structures 300, arc plate structures 500 and cleaning brush structures 600 are fixed on the fixed assembly frame 200 in this embodiment, and the two groups of fruit cups 100 conveying groups are respectively cleaned. Among them, the two groups of conveying structures 300 can share the same sprocket shaft 330 and two bearing seats 340.

[0063] Please refer to Figure 4-Figure 5 In this embodiment, the fruit cup restoring device 012 includes an arc plate structure 500 .

[0064] Optionally, the arc plate structure 500 is two special-shaped elliptical arc plates, and a hollow structure 520 is provided on the arc plate structure 500 for passing the sprocket shaft 330; the arc plate structure 500 is detachably connected to the fixed assembly frame 200. It can be understood that the arc plate structure 500 in this embodiment has a hollow structure 520 for passing the sprocket shaft 330, and the arc plate structure 500 can be disassembled separately without affecting other structures.

[0065] Please refer to Figure 6-Figure 7Specifically, a friction surface 510 is provided on the arc plate structure 500, and the friction surface 510 includes a first arc-shaped friction surface 511 and a second arc-shaped friction surface 512. The first arc-shaped friction surface 511 is located at the input end of the transmission structure 300, and the curvature of the first arc-shaped friction surface 511 is relatively gentle relative to the curvature of the second arc-shaped friction surface 512; the second arc-shaped friction surface 512 is located at the output end of the transmission structure 300, and the curvature of the second arc-shaped friction surface 512 is consistent with the curvature of the circular arc surface, and the curvature of the second arc-shaped friction surface 512 is consistent with the curvature of the guide surface 411 of the return disk 410. It is understandable that such an arrangement enables the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 to contact the first arcuate friction surface 511 or the second arcuate friction surface 512 when the fruit cup 100 is conveyed along the guide surfaces 411 on both sides, so that the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 can rotate synchronously in the clockwise direction.

[0066] It is worth mentioning that a patterned conveyor belt can be arranged on the arc plate structure 500, and the friction surface 510 is formed by the patterned surface on the patterned conveyor belt. In particular, due to the different transported materials and the different conveying angles, the pattern shape and height are required to be different; the pattern can be open or closed. In this embodiment, the patterned conveyor belt arranged on the arc plate structure 500 is a grass-shaped patterned conveyor belt.

[0067] In this embodiment, the fruit cup returning device 012 includes a cleaning brush structure 600 ; the cleaning brush structure 600 is disposed at the output end of the conveying structure 300 and is used to clean the fruit cup 100 .

[0068] Please refer to Figure 5-Figure 7 In this embodiment, the cleaning brush structure 600 includes a cleaning brush 610 and a telescopic adjustment mechanism 620. The telescopic adjustment mechanism 620 is connected to the fixed assembly frame 200; the cleaning brush 610 is connected to the telescopic adjustment mechanism 620, and the telescopic adjustment mechanism 620 is used to adjust the distance between the cleaning brush 610 and the fruit cup 100; the cleaning brush 610 is used to clean the fruit cup 100.

[0069] It is understandable that the distance between the cleaning brush 610 and the fruit cup 100 is adjusted by the telescopic adjustment mechanism 620 to ensure that the cleaning brush 610 effectively contacts the fruit cup 100, thereby efficiently completing the cleaning of the fruit cup 100. It is worth mentioning that for fruit cups 100 of different sizes, the position of the cleaning brush 610 can be adjusted by the telescopic adjustment mechanism 620 to adjust the distance between the cleaning brush 610 and the fruit cup 100, so that the cleaning brush 610 can effectively contact the fruit cup 100 to achieve effective cleaning, and at the same time, it can prevent the brush from being excessively squeezed by the fruit cup 100, resulting in damage to the cleaning brush 610.

[0070] In this embodiment, the rotation direction of the fruit cup 100 is clockwise, and the rotation direction of the cleaning brush structure 600 is opposite to the rotation direction of the fruit cup 100 .

[0071] It can be understood that when the cleaning brush 610 cleans and maintains the fruit cup 100, the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 rotating clockwise will not be affected by the movement of the cleaning brush 610 to cause relative movement, thereby avoiding inadequate cleaning of the fruit cup 100; at the same time, the counterclockwise rotating cleaning brush will clean the surfaces of the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 passing by and the surfaces of the first supporting portion 111 and the second supporting portion 112 of the body 110, thereby increasing the area of ​​the fruit cup 100 that can be cleaned and the cleaning effect.

[0072] Please refer to Figure 6-Figure 7 The working principle of the fruit cup return device 012 is:

[0073] The chain 310 drives the sprocket body 320 to move synchronously, and then the sprocket body 320 drives the return disk 410 to rotate synchronously. When the fruit cup 100 moves to the return disk 410 driven by the chain 310, the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 contact the guide surfaces 411 of the return disk 410 on both sides respectively, and the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 are given an upward force by the guide surfaces 411 of the return disk 410, so that the first supporting portion 111 and the second supporting portion 112 of the fruit cup 100 are located on the same horizontal line, that is, the fruit cup 100 is returned to the center.

[0074] When the fruit cup 100 is returned to its original position and transported along the guide surfaces 411 on both sides, the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 come into contact with the first arc-shaped friction surface 511 or the second arc-shaped friction surface 512, so that the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 rotate clockwise synchronously.

[0075] When the fruit cup 100 is transferred to the output end, the counterclockwise rotating cleaning brush cleans the surfaces of the first limiting portion 120 and the second limiting portion 130 of the fruit cup 100 and the surfaces of the first supporting portion 111 and the second supporting portion 112 of the body 110 .

[0076] In summary, the fruit cup return device 012 proposed in the utility model, by setting a synchronously rotating conveying structure 300 and a return structure 400, enables the fruit cup 100 to be conveyed to the return structure 400, and the return structure 400 can contact the fruit cup 100 and give an upward force to the fruit cup 100 to return the fruit cup 100. At the same time, the fruit cup 100 will not have a large area of ​​friction and scratches at the same position of the return structure 400 during the process of contacting the return structure 400 and returning to the original position, thereby reducing the wear of the return structure 400 and increasing the service life of the return structure 400; and by setting an arc plate structure 500, the fruit cup 100 after returning to the original position contacts the friction surface 510 of the arc plate structure 500 under the drive of the conveying structure 300, so that the fruit cup 100 can rotate, thereby avoiding the fruit cup 100 from being inadequately cleaned in the subsequent process.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
