[0002] The present invention relates to the technical field of equipment for fruits and vegetables, and more particularly to a fruit and vegetable sorting and conveying device and a fruit and vegetable sorting equipment. [Background technology]

[0003] When fruits and vegetables reach maturity, they are generally harvested and sorted to separate fruits and vegetables of different qualities. In a fruit and vegetable sorting system, a conveyor for conveying the fruits and vegetables is typically clamped to a conveyor belt, and a series of sorting operations are performed while the fruits and vegetables are being transported by the conveyor.

[0004] In the fruit and vegetable conveying device according to the related art, the gap between the bar brushes is too large, so that fruit and vegetables tend to fall into the gap between the fruit and vegetable conveying device and the bar brushes, resulting in the loss of the fruit and vegetables. Summary of the Invention

[0005] The present invention provides a fruit and vegetable sorting and conveying device and a fruit and vegetable sorting facility that can achieve the technical effect of stably holding at least fruit and vegetables on a conveyor belt and smoothly carrying out the fruit and vegetable sorting process.

[0006] In one embodiment, the present invention provides a fruit and vegetable sorting and conveying apparatus which may include a roller assembly, a support frame, and a base; The roller assembly may be disposed on the support frame, the support frame being movably connected to the base and used to place fruit or vegetables together with the roller assembly, and the roller assembly may be further used to roll the fruit or vegetables, The support frame may include a support portion and two mounting arms connected to both ends of the support portion, the roller assembly may be disposed between the two mounting arms, and the mounting arms may be provided with an escape step for inserting a bar brush, thereby reducing the relative distance between the end of the bar brush and the axis of the roller assembly.

[0007] According to the above embodiment, the mounting arm is provided with an escape step for the bar brush to be inserted, which effectively reduces the distance between the end of the bar brush and the axis of the roller assembly. By doing so, when the dimensions of the fruit and vegetable sorting and conveying device are constant, the vertical height of the bar brush is effectively reduced, and the vertical distance between the bar brush and the roller assembly is reduced, thereby effectively preventing fruit and vegetable from getting caught in the gap between them. This further ensures that the fruit and vegetable sorting and conveying device can transport fruit and vegetable stably, prevents fruit and vegetable from being damaged by falling, and ensures that the sorting process is completed smoothly while transporting fruit and vegetable by the fruit and vegetable sorting and conveying device.

[0008] In an optional embodiment, the base may include a reinforcing portion and two opposing clamping portions, the reinforcing portion being connected to the tips of the two clamping portions, and the clamping portions may be used to clamp to a conveyor belt, and the reinforcing portion and the two clamping portions are integrally molded in a U-shape.

[0009] According to the above embodiment, the reinforcing portion is connected to the tips of the two clamps, thereby increasing the yield strength of the base and significantly improving the clamping force of the clamps against the conveyor belt, preventing the fruit and vegetable sorting and conveying device from rattling and even falling due to insufficient clamping force of the clamps while conveying fruit and vegetables. Furthermore, the two clamps and the reinforcing portion are integrally molded into a U-shape, further increasing the structural strength and yield strength of the base, ensuring that the clamps are stably clamped to the conveyor belt.

[0010] In an optional embodiment, the mounting arm may be movably connected to the base, and the mounting arm may be used to tip the support frame sideways away from the external force upon application of an external force.

[0017] According to the above embodiment, the connecting member is U-shaped and fits the shape of the support frame. The support frame is connected to the base via the connecting member, and the bottom of the support part can be engaged with or separated from the base. The connecting member can prevent the support frame from being completely detached from the base when the support part is separated from the base.

[0018] In an optional embodiment, a position limiting recess may be provided on each side of the top of the base, and a position limiting protrusion may be provided on each side of the bottom of the support, and the position limiting protrusion is fitted into the position limiting recess to engage the support frame with the base.

[0019] According to the above embodiment, by configuring the two position limiting convex portions to fit into the two position limiting concave portions, the support frame is stably attached to the base, and it is prevented that the support frame is subjected to uneven force and falls over, causing fresh produce to fall.

[0020] In an optional embodiment, the mounting arm may be provided with a protruding block, which is used to move the support frame, the roller assembly and the fruit or vegetable vertically upward relative to the base and release the support frame from engagement with the base by the supporting action of the weighing device in order to weigh the support frame, the roller assembly and the fruit or vegetable by the weighing device.

[0021] According to the above embodiment, the protruding block disengages the support frame from the base due to the supporting action of the weighing device, thereby allowing accurate weight information of the fruit or vegetable to be obtained.

[0022] In an optional embodiment, the roller assembly may include a rotating shaft rotatably connected to the support frame, and two first rollers and one second roller disposed on the rotating shaft, the second roller being positioned between the two first rollers and being used together with the two first rollers to support the fruit or vegetables and to roll the fruit or vegetables.

[0037] To provide a fruit and vegetable sorting equipment used to perform a sorting process on collected fruit and vegetable, which is particularly suitable for sorting fruits, has good sorting effect, and is highly efficient.

[0038] Referring to FIG. 1, the fruit and vegetable sorting equipment includes a plurality of fruit and vegetable sorting and conveying devices 10, a conveyor belt 20, roller rails 30, a detection device (not shown), a weighing device (not shown), and a fruit and vegetable removal device 40.

[0039] In this embodiment, all of the multiple fruit and vegetable sorting and conveying devices 10 are clamped to the conveyor belt 20, so that the fruit and vegetable sorting and conveying devices 10 with fruit and vegetable 50 placed on them follow the conveyor belt 20 to perform the sorting process. The roller rails 30, detection device, weighing device, and fruit and vegetable removal device 40 are all arranged around the conveyor belt 20. The detection device is used to detect the outer skin of the fruit and vegetable 50 placed on the fruit and vegetable sorting and conveying device 10. The weighing device is used to weigh the fruit and vegetable 50 placed on the fruit and vegetable sorting and conveying device 10. The fruit and vegetable removal device 40 is used to remove the fruit and vegetable 50 placed on the fruit and vegetable sorting and conveying device 10.

[0040] 2 to 5, a fruit and vegetable sorting and conveying device 10 according to the present invention includes a roller assembly 100, a support frame 200, a connecting member 300, and a base 400.

[0041] Of these, the roller assembly 100 is disposed on a support frame 200, which is movably connected to a base 400 via a connecting member 300 and is used to place fruit or vegetables 50 together with the roller assembly 100.

[0042] In this embodiment, the base 400 includes a reinforcing portion 420 and two opposing clamping portions 410, which clamp to the conveyor belt 20 and move the fruit and vegetable sorting and conveying device 10 along with the conveyor belt 20. The reinforcing portions 420 are connected to the ends of the two clamping portions 410, which increases the yield strength of the base 400 and significantly improves the clamping force of the clamping portions 410 against the conveyor belt 20. This prevents the fruit and vegetable sorting and conveying device 10 from rattling and even falling due to insufficient clamping force of the clamping portions 410 while the fruit and vegetable sorting and conveying device 10 is conveying the fruit and vegetable 50, preventing the fruit and vegetable 50 from being damaged by falling, and ensuring that the sorting process is completed smoothly while the fruit and vegetable sorting and conveying device 10 is conveying the fruit and vegetable 50.

[0043] Specifically, the reinforcing portion 420 and the two clamping portions 410 are integrally molded in a U-shape, which further increases the structural strength and yield strength of the base 400 and ensures that the clamping portions 410 are stably clamped to the conveying belt 20.

[0044] In actual application, the roller assembly 100 is also used to roll the fruit or vegetable 50. A roller rail 30 and a detection device are provided at the start of the conveyor belt 20, and when the base 400 is clamped to the conveyor belt 20, the roller assembly 100 is placed on the roller rail 30. In this state, the fruit or vegetable 50 is placed between the roller assemblies 100 of two adjacent fruit or vegetable sorting and conveying devices 10, and rotates following the two adjacent roller assemblies 100. While the fruit or vegetable 50 is rotating, the detection device performs full-periphery appearance detection on the outer skin of the fruit or vegetable 50 to collect image information of the outer skin of the fruit or vegetable 50.

[0045] Of course, in other embodiments, even if the fruits and vegetables 50 are placed on the support frame 200 and roller assembly 100 of the same fruit and vegetable sorting and conveying device 10, the roller assembly 100 can rotate while being guided by the roller rail 30, thereby allowing the fruits and vegetables 50 to roll.

[0046] The roller assembly 100 comprises a rotating shaft 110 rotatably connected to a support frame 200, and two first rollers 120 and one second roller 130 arranged on the rotating shaft 110, and the one second roller 130 is located between the two first rollers 120 and may be used to support the fruits and vegetables 50 together with the two first rollers 120 and to roll the fruits and vegetables 50.

[0047] In this embodiment, both ends of the rotation axis 110 are respectively connected to two mounting arms of the support frame 200, and the two first rollers 120 rotate while being guided by the roller rails 30, which can rotate the second rollers 130, thereby rolling the fruit or vegetable 50 and facilitating the collection of a full-circumference skin image of the fruit or vegetable 50.

[0048] The first roller 120 may have a larger diameter than the second roller 130 and may be used to roll the fruit or vegetable 50 while rotating while being guided by the roller rail 30 .

[0049] In this embodiment, the second roller 130 is formed to have a smaller diameter than the first roller 120 so as to fit the shape of the fruit or vegetable 50 and improve the rolling effect of the fruit or vegetable 50 .

[0050] The support frame 200 has a support portion 220 and two mounting arms 210 connected to both ends of the support portion 220, and the roller assembly 100 is arranged between the two mounting arms 210. The mounting arms 210 may be provided with an escape step 212 for the bar brush 60 to be inserted into, thereby reducing the relative distance between the end of the bar brush 60 and the axis of the roller assembly 100.

[0051] In this embodiment, the mounting arm 210 is provided with an escape step 212 for the bar brush 60 to insert, which effectively reduces the distance between the end of the bar brush 60 and the axis of the roller assembly 100, i.e., the distance between the rotation axis 110 of the first roller 120 and the end of the bar brush 60.Therefore, when the dimensions of the fruit and vegetable sorting and conveying device 10 are constant, the vertical height of the bar brush 60 is effectively reduced, and the vertical distance between the bar brush 60 and the roller assembly 100 is reduced.This effectively prevents the fruit and vegetable 50 from getting caught in the gap between the bar brush 60 and the roller assembly 100, and further ensures that the fruit and vegetable sorting and conveying device 10 can stably convey the fruit and vegetable 50, preventing the fruit and vegetable 50 from being damaged by falling, and ensuring that the sorting process is completed smoothly while the fruit and vegetable sorting and conveying device 10 is transporting the fruit and vegetable 50.

[0052] Specifically, the distance between the relief step 212 and the conveyor belt 20 clamped by the clamping portion 410 is 100 mm (shown in FIG. 7).

[0053] The mounting arm 210 may be movably connected to a base 400 via a connecting member 300 .

[0054] In this embodiment, the support portion 220 and the two mounting arms 210 are both formed in a U-shape, and the support portion 220 is placed on top of the base 400, and the mounting arms 210 are movably connected to the base 400 via the connecting member 300, so that the support frame 200 is movably connected to the base 400.

[0055] Furthermore, the roller assembly 100 is guided by the roller rail 30 and can rotate together with the support frame 200 relative to the base 400 via the connecting member 300, specifically by 35°.In this state, the escape step 212 can reduce the distance of the bar brush 60 from the conveying belt 20 by 10 mm, significantly reducing the possibility of the fruits and vegetables 50 becoming caught in the space between the bar brush 60 and two adjacent fruit and vegetable sorting and conveying devices 10 during operation.

[0056] The support portion 220 includes two spaced apart projections 211, and the two projections 221 may be used to place the fruit or vegetable 50 together with the roller assembly 100.

[0057] In this embodiment, the two protrusions 221 and the roller assembly 100 each come into contact with multiple points on the fruit or vegetable 50, thereby increasing the contact area between the support frame 200 and the fruit or vegetable 50, thereby improving the adhesion of the support frame 200 and the roller assembly 100 to the fruit or vegetable 50. In addition, the provision of the protrusions 221 reduces the probability of collision between the fruit or vegetable 50 and the support frame 200 while the fruit or vegetable sorting and conveying device 10 is conveying the fruit or vegetable 50, significantly reducing damage to the fruit or vegetable.

[0058] The base 400 further includes a connection portion 430 provided at the top of the reinforcing portion 420, and a movable chamber 431 is provided in the connection portion 430 so as to be open. The connection member 300 may be movably inserted into the movable chamber 431, with one end connected to one mounting arm 210 and the other end connected to the other mounting arm 210.

[0059] In this embodiment, the connecting member 300 is U-shaped and fits the shape of the support frame 200. The support frame 200 is connected to the base 400 via the connecting member 300, and the bottom of the support portion 220 can be engaged with or separated from the base 400. The connecting member 300 can prevent the support frame 200 from being completely detached from the base 400 when the support portion 220 is separated from the base 400.

[0060] Position limiting recesses 432 are provided on both sides of the top of the connecting portion 430, and position limiting protrusions 222 are provided on both sides of the bottom of the support portion 220, and the support frame 200 may be engaged with the base 400 by fitting the position limiting protrusions 222 into the position limiting recesses 432.

[0061] In this embodiment, the two position limiting protrusions 222 are fitted into the two position limiting recesses 432, respectively, so that the support frame 200 is stably attached to the base 400, and it is prevented that the support frame 200 is subjected to uneven force and falls over, causing the fruits and vegetables 50 to fall.

[0062] When fruit or vegetable 50 is placed on support frame 200, the weight of fruit or vegetable 50 acts on support frame 200 and further acts on position limiting recess 432 via position limiting protrusion 222 of support frame 200, thereby stably engaging support frame 200 with base 400 and preventing support frame 200 from tipping over and therefore coming off.

[0063] When it is necessary to remove the produce, as shown in Figure 6, the produce removal device 40 typically applies a vertical upward force F to the mounting arm 210 of the support frame 200, causing the position limiting protrusion 222 to separate from the position limiting recess 432.The mounting arm 210 then causes the support frame 200 to tip sideways against the base 400 toward the side away from the produce removal device 40, causing the produce 50 to fall from the support frame 200, thereby removing the produce 50.

[0064] It will be understood that since the support frame 200 is connected to the base 400 via the connecting member 300, the support frame 200 is prevented from completely detaching from the base 400 when the support frame 200 is in a sideways position.

[0065] The mounting arm 210 is provided with a protruding block 211, which may be used to move the support frame 200, roller assembly 100, and fruit and vegetable 50 vertically upward relative to the base 400 through the supporting action of the weighing device in order to weigh the support frame 200, roller assembly 100, and fruit and vegetable 50 using the weighing device, and to release the engagement between the support frame 200 and the base 400.

[0066] In this embodiment, the weighing devices are weighing plates provided on both sides of the mounting arm 210, and the weighing plates (not shown) are equipped with weight sensors (not shown). When the fruit and vegetable sorting and conveying device 10 is moved to the position of the weighing devices by the conveyor belt 20, the weighing devices come into contact only with the protruding blocks 211 of the mounting arm 210. In other words, the support frame 200, the roller assemblies 100, and the fruit and vegetable 50 are placed on the weighing devices via the protruding blocks 211 of the mounting arm 210. By increasing the height of the weighing plates, the roller assemblies 100, the support frame 200, and the fruit and vegetable 50 placed on the support frame 200 are released from the base 400, and the weight sensors obtain the weights of the support frame 200, the roller assemblies 100, and the fruit and vegetable 50. Accurate weight information of the fruit and vegetable 50 is obtained through a series of calculations.

[0067] As described above, the present invention provides a fruit and vegetable sorting and conveying device 10 and fruit and vegetable sorting equipment, in which the clamping units 410 clamp to the conveyor belt 20, allowing the fruit and vegetable sorting and conveying device 10 to move along with the conveyor belt 20. Reinforcing units 420 are connected to the ends of the two clamping units 410 to increase the yield strength of the base 400 and significantly improve the clamping force of the clamping units 410 on the conveyor belt 20. This prevents the fruit and vegetable sorting and conveying device 10 from rattling and even falling due to insufficient clamping force of the clamping units 410 while the fruit and vegetable sorting and conveying device 10 is conveying the fruit and vegetable 50, preventing the fruit and vegetable 50 from being damaged by falling, and ensuring that the sorting process is completed smoothly while the fruit and vegetable sorting and conveying device 10 is conveying the fruit and vegetable 50.

[0068] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art can make various modifications and variations to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
