Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fruit and vegetable sorting, and particularly relates to a turnover device and a sorting equipment. BACKGROUND

[0002] Fruits or spherical vegetables are usually sorted and graded by manual operation, and manual sorting is uneven in size and low in efficiency, so sorting equipment for fruits and vegetables is developed. In the sorting equipment, fruits and vegetables are generally conveyed by linear conveying, that is, the fruits are conveyed from an initial feeding belt conveyor to a middle one-way arrangement conveyor, and then conveyed to a rotating device of the sorting equipment through the one-way arrangement conveyor, so that the fruits are sequentially rotated and sorted.

[0003] The sorting equipment drives the fruits to move in a circle through the rotating device, so that the fruits sequentially pass through a visual shooting device located above the fruits, and the visual shooting device can shoot and collect quality information of each fruit for subsequent classification.

[0004] However, the fruits are pushed to move forward along the loading table by the pushing member, so that the visual shooting device can shoot the fruits, and there is a gap between the pushing rod and the loading table. During the process of pushing the fruits to move forward in a predetermined direction, the fruits are easily stuck between the pushing rod and the loading table. Once the fruit sticking phenomenon occurs, the sorting equipment needs to be stopped to take out the stuck fruits, thereby reducing the efficiency of fruit sorting. SUMMARY

[0005] The purpose of the embodiments of the present application is to provide a turnover device, which aims to solve the problem of how to improve the efficiency of fruit sorting.

[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is:

[0031] Please see Figures 1 to 3 This application provides a flipping device 100 for conveying a target object along a predetermined trajectory. The target object can be a fruit, vegetable, or other rotating object, wherein the fruit and vegetable are spherical or rotating. In this embodiment, the flipping device 100 is used to convey fruit 101. In other embodiments, the flipping device 100 can also be used to convey vegetables; there is no limitation here.

[0032] Please see Figures 1 to 3The turnover device 100 comprises a rotating structure 200 and a driving structure 300. The rotating structure 200 comprises pushing members 205, a loading table 220 for carrying fruits 101, and a pushing disc 206 arranged opposite to the loading table 220. The loading table 220 is provided with feeding grooves 221 for conveying the fruits 101. The pushing members 205 are arranged across the feeding grooves 221 and are spaced along the extension path of the feeding grooves 221. Any two adjacent pushing members 205 form a pushing interval 222 for positioning the target objects. One fruit 101 is arranged between any two adjacent pushing members 205. It can be understood that the loading table 220 supports the bottom of the fruit 101 from top to bottom. Two adjacent pushing members 205 are respectively located at two sides of the fruit 101. The minimum distance between the two pushing members 205 is greater than the maximum diameter of the fruit 101, so as to avoid the fruit 101 from being stuck between the two pushing members 205.

[0033] Please refer to Figures 4 to 5 The driving structure 300 comprises a first driver 301 and a second driver 302. The second driver 302 drives each pushing member to move along the extension path of the feeding groove 221, so as to move each target object located in the feeding groove 221 forward along the feeding groove 221. It can be understood that the fruit 101 is located between two adjacent pushing members 205. In the moving direction of each pushing member, the pushing member 205 located at the rear abuts against the side surface of the fruit 101. The first driver 301 is used for driving each pushing member 205 to rotate, i.e. each pushing member 205 rotates around the central axis thereof under the driving of the first driver 301. At the same time, the pushing member 205 drives the corresponding fruit 101 to roll forward along the extension path of the feeding groove 221. In this way, the fruit 101 can be prevented from being stuck between the pushing member 205 and the loading table 220, the smoothness of the fruit 101 is improved, and the efficiency of subsequent sorting is improved.

[0034] The turnover device 100 comprises a rotating structure 200 and a driving structure 300. The rotating structure 200 comprises a loading table 220 and pushing members 205.

The second driver 302 is used for driving each pushing member to move along the extension path of the feeding groove 221. Thus, the pushing member 205 applies a forward pushing force and an upward rolling force to the fruit 101. The fruit 101 is constantly moved forward and rolled relative to the pushing member 205. The fruit 101 can be prevented from being stuck between the loading table 220 and the pushing member 205, i.e. the phenomenon of stuck fruit is avoided. The smoothness of the fruit 101 is improved, and the sorting efficiency of the fruit 101 is improved.

One end of the pushing member 205 is rotationally connected to the edge of the material pushing disc 206, and the other end of the pushing member 205 extends outward to above the material loading table 220. A plurality of pushing members 205 are arranged along the circumference of the material pushing disc 206 in a spaced manner, and the plurality of pushing members 205 are arranged in a radial manner on the material pushing disc 206. The second driver is used to drive the material pushing disc 206 to rotate, so as to drive the pushing member to exert a forward pushing force on the fruit 101, so as to drive the fruit 101 to move along the feeding groove 221.

The pushing member 205 located at the rear also exerts a rolling force on the fruit 101, and the direction of the rolling force is substantially perpendicular to the surface of the material loading table 220 on which the feeding groove 221 is opened. The pushing member 205 located at the front does not directly exert a force on the fruit 101, so that the fruit 101 continuously moves forward and rolls, and the phenomenon of fruit jamming does not occur.
