Description

Technical Field

[0002] With the improvement of living standards, consumers have higher and higher requirements for the quality of fruits; after sorting, fruits can be priced according to grades and sold to different groups of people. With the development of science and technology, mechanical sorting has gradually developed from manual sorting, such as size and weight sorting, but the appearance quality still needs to rely on manual sorting. However, relying on human experience is easily affected by human emotions and state, and there is a great deal of uncontrollability, which can easily cause the outflow of poor appearance quality. At this stage, computer vision technology is mature and widely used, and computer vision is beginning to be used to replace manual detection and sorting of appearance defects and colors, solving labor problems and improving efficiency and sorting quality.

[0003] For spherical fruits like tomatoes, passion fruit, and citrus, when using computer vision for non-destructive appearance sorting on the assembly line, it is necessary to conduct a full-scale inspection of the surface of the cones to prevent appearance defects such as spots and insect bites. In the case of single computer vision and fixed position, the cones need to be transported while rotating. The existing rotation while transporting basically relies on friction to drive the cones to rotate and transport. There are defects such as rotation in only one direction and inability to conduct full-scale inspection, and the cones sometimes rotate and sometimes do not rotate due to poor friction contact. It is easy to miss the detection of poor external quality, and the sorting accuracy is not high enough. Utility Model Content

[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] Please refer to Figures 1 to 4 , a cone sorting conveying system, characterized in that: it comprises a first conveying component, a second conveying component 2 and a sorting component 3;

[0021] The first conveying assembly comprises a conveying chain 1;

[0022] The sorting assembly 3 includes a fruit bracket 31 and a driving wheel 32. The fruit brackets 31 are arranged on the first conveying assembly in sequence according to a preset distance. Each of the fruit brackets 31 is symmetrically provided with two driving wheels 32. The driving wheels 32 are rotatably connected to the fruit brackets 31.

[0023] The moving direction of the second conveying component 2 is parallel to the moving direction of the first conveying component. There are two second conveying components 2. Each second conveying component 2 is transmission-connected to one of the driving wheels 32 on each of the fruit brackets 31. Each second conveying component 2 is provided with a driving motor 33 independent of each other. The two second conveying components are symmetrically arranged on both sides of the conveying chain.

[0024] From the above description, it can be seen that the beneficial effect of the utility model is that: by setting two kinds of conveyor belts, they are responsible for the transportation of cones 4 and the rotation of cones 4 respectively. The principle is that two driving wheels 32 are symmetrically arranged on the fruit bracket 31, wherein the fruit bracket 31 is arranged on the conveying chain 1 of the first conveying component and moves with the first conveying component, that is, the cones 4 placed on the fruit bracket 31 move with the first conveying component; at the same time, the driving wheel 32 rotatably connected to the fruit bracket 31 is transmission-connected with the second conveying component 2, the rotation speed and regularity of the driving wheel 32 are controlled by the second conveying component 2, and the two second conveying components 2 are respectively controlled by two driving motors 33, that is, the rotation speed and direction of the two driving wheels 32 on each fruit bracket 31 are independent of each other, and the driving wheel 32 or other accessories on the driving wheel 32 are used to apply friction to the cones 4, thereby prompting the cones 4 to achieve the expected rotation effect (forward, reverse and flipping, etc.), and then be captured by machine vision, and a stable rotation effect is achieved when the cones 4 are transported, and then the cones 4 are sorted to improve the sorting accuracy.

[0025] Specifically, the two second conveying components 2 are symmetrically arranged to ensure that the two driving wheels 32 on the fruit bracket 31 are also symmetrical to the first conveying component, so that they can serve as a reference to each other when controlling the operation of the second conveying components 2, thereby reducing the control difficulty and improving the convenience of using the device.

[0026] In an embodiment of the utility model, the sorting component 3 also includes a rotating shaft 34, each of the fruit trays 31 is provided with two rotating shafts 34, the two rotating shafts 34 are perpendicular to the travel direction of the first conveying component and are symmetrically arranged at both ends of the fruit tray 31, and each of the driving wheels 32 is assembled and connected with the corresponding rotating shaft 34.

[0027] As can be seen from the above description, the rotating shaft 34 rotatably connected to the fruit bracket 31 is assembled and connected with the driving wheel 32, so that the fruit bracket 31 and the driving wheel 32 are rotatably connected. At the same time, the rotating shaft 34 is used to control the installation position of the driving wheel 32. The position of the rotating shaft 34 can be adjusted according to actual needs and the setting angle of the second transmission component 2, and then the setting position of the driving wheel 32 can be adjusted to improve the versatility of the device. Preferably, at least two rotating shaft 34 installation holes of different heights are set on the fruit bracket 31.

[0028] In an embodiment of the utility model, the sorting component 3 further includes a fruit supporting wheel 35 , and two fruit supporting wheels 35 are symmetrically provided on each fruit support 31 . The fruit supporting wheels 35 are assembled and connected to the rotating shaft 34 , and the two fruit supporting wheels 35 are located between the two driving wheels 32 .

[0029] As can be seen from the above description, a fruit support wheel 35 is arranged on the rotating shaft 34, and the fruit support wheel 35 is in direct contact with the cone 4 to prevent the cone 4 from contacting with the driving wheel 32. The principle is that since the driving wheel 32 is connected to the second transmission assembly 2 by transmission, it is inevitable to arrange a transmission structure on the driving wheel 32. When the transmission structure contacts the cone 4, it will damage the surface of the cone 4, causing the quality of the cone 4 to decrease. In addition, it is found through experiments that if the driving wheel 32 is in direct contact with the cone 4, debris will accumulate on the surface of the driving wheel 32. Long-term operation will cause the transmission between the driving wheel 32 and the second transmission assembly 2 to be blocked, resulting in the inability to achieve the rotation effect, and in serious cases, the machine will be damaged. In order to solve this problem, a fruit support wheel 35 is arranged to contact with the cone 4, that is, the transmission and rotation are realized by the driving wheel 32 and the fruit support wheel 35 respectively.

[0030] It can be understood that the driving wheel 32 and the fruit supporting wheel 35 can be two components independent of each other, or can be two areas on one component that realize different functions.

[0031] In the embodiment of the present utility model, the outer diameter of the fruit supporting wheel 35 is smaller than the outer diameter of the driving wheel 32 .

[0033] In the embodiment of the present utility model, a buffer layer is provided on the circumference of the fruit supporting wheel 35 .

[0034] From the above description, it can be seen that a buffer layer is provided on the surface of the fruit support wheel 35 to prevent the rigid material on the surface of the fruit support wheel 35 from directly interacting with the cones 4, thereby damaging the cones 4 and reducing the loss rate of the cones 4. Preferably, the buffer layer is made of a material that can provide a buffering effect and has sufficient friction, such as rubber, silicone, etc.

[0035] In the embodiment of the utility model, the driving wheel 32 is circumferentially provided with first transmission teeth, and the driving wheel 32 is transmission-connected to the second transmission assembly 2 via the transmission teeth.

[0036] Furthermore, the second transmission component 2 includes a transmission belt 21, and the transmission belt 21 is provided with a rack matched with the first transmission tooth.

[0037] From the above description, it can be seen that a first transmission tooth is arranged on the circumference of the driving wheel 32 to cooperate with the rack on the second conveying component 2, so as to realize the controllability of the rotation of the driving wheel 32, that is, by controlling the speed and direction of the second conveying component 2, the rotation directions of the two driving wheels 32 can be adjusted respectively, so that under the machine vision, the rotation mode of the cones 4 can be adjusted in real time to ensure that the cones 4 can be fully captured by the machine vision, thereby completing the sorting.

[0038] In an embodiment of the utility model, the first transmission assembly further comprises a main sprocket, a slave sprocket and a bracket; the transmission chain is drivingly connected to the main sprocket and the slave sprocket, and the main sprocket and the slave sprocket are assembled and connected to the bracket.

[0039] From the above description, it can be seen that the ring conveyor chain is composed of a transmission chain arranged around the main sprocket and the slave sprocket. Specifically, the first conveying component is also provided with a motor with a reducer, which drives the main sprocket to rotate through the output of the reducer, thereby driving the conveying chain to rotate, thereby realizing smooth transportation of the cones and avoiding jitter caused by sudden changes in travel speed during transportation.

[0040] In the embodiment of the present utility model, the fruit support 31 comprises a receiving plate 36, and the angle between the receiving plate 36 and the horizontal plane is an acute angle.

[0041] From the above description, it can be seen that the fruit tray 31 is provided with a receiving plate 36 which forms an acute angle with the horizontal plane, so that the gravity of the fruit on the fruit tray 31 is respectively shared on the receiving plate 36 and the driving wheel 32 and its components, thereby ensuring the friction between the cones 4 and the driving wheel 32 and its components, and ensuring the effectiveness of the rotation control.

[0042] In an embodiment of the present invention, a control center is further included, and the control center is used to control the operation of the first conveying component and the second conveying component 2.

[0043] From the above description, it can be seen that a control center is set to control the operation of the first conveying component and the second conveying component 2 respectively, without manual participation in the control, and the control center is used to formulate control logic to achieve automation of sorting.
