Description

TECHNICAL FIELD

In step 1, peanuts are put into the peanut vibration feeding tray 1.

In step 2, the controller controls the vibration of the peanut vibrating feed tray 1 and sends the peanuts from the circular track of the peanut vibrating feed tray 1 to the discharge port of the peanut vibrating feed tray 1 sequentially.

In step 3, the controller controls the cut-off cylinder 51. When the telescopic shaft of the cut-off cylinder 51 retracts, the discharge port of the peanut vibrating feeding tray 1 is no longer blocked, and the peanuts enter the first conveyor belt 29.

In step 4, the first camera sensor 48 detects the sizes, shapes and positions of the peanuts on the first conveyor belt 29 and transmits the data to the controller, and the controller controls subsequent components to perform corresponding actions.

In step 5, the controller determines whether the peanuts are suitable to be used as seeds, when the detected peanuts are suitable to be used as seeds and the heads of the peanuts are towards a moving direction of the first conveyor belt 29, then the controller controls the first horizontal single-arm robot, the first longitudinal single-arm robot 5 and the first pneumatic finger 6 of the first bracket assembly 4 to grab peanuts onto the second conveyor belt 35.

In step 6, the second camera sensor 49 detects the positions and states of the peanuts on the second conveyor belt 35 which move in an opposite direction to the first conveyor belt 29.

In step 7, the data is transmitted to the controller after the peanuts on the second conveyor belt 35 have reached the predetermined position which is detected by the second camera sensor 49. The peanuts follow the second conveyor belt 35 to move to the end thereof and fall longitudinally into the groove of the first direction conversion disc 45. The first direction conversion motor 44 drives the first direction conversion disc 45 to rotate, so that the peanuts are changed from a horizontal state to a vertical state, and then the first direction conversion motor 44 is stopped.

In step 8, the third horizontal single-arm robot 11 and the third longitudinal single-arm robot 12 drive the third pneumatic finger 13 to move to the position corresponding to the vertical peanuts. The third pneumatic finger 13 grabs the peanuts and applies a clamping force to the peanuts to form small openings thereon.

Each of the fourth pneumatic finger 15 and the fifth pneumatic finger 17 grabs a corresponding side of a peanut, and moves in an opposite direction to divide the peanut shell into two parts.

In step 9, the divided peanut seeds and the peanut shells fall into the screening mechanism through the first inclined discharge outlet 53, the peanut seeds and the peanut shells are separated by the movement of the screening plate 55, and the peanut seeds are collected to achieve the desired effect.

In step 10, when the detected peanuts are suitable to be used as seeds and heads of the peanuts are towards a moving direction which is opposite to the moving direction of the first conveyor belt 29. The second single-arm robot 7, the second miniature single-arm robot 8 and the second pneumatic finger 9 of the first bracket assembly are controlled to grab the peanuts onto the third conveyor belt 41, and the unqualified peanuts follow the movement of the first conveyor belt 29 and fall off.

In step 11, the third camera sensor 50 detects the positions and states of the peanuts on the third conveyor belt 41 which move in the same direction as the first conveyor belt 29.

After the second camera sensor 49 detects that the peanuts on the second conveyor belt 35 have reached the predetermined position, the data is transmitted to the controller to control the first direction conversion motor 44, so as to drive the first direction conversion disc 45 to move. The peanuts may fall longitudinally into the groove of the first direction conversion disc 45, and the first direction conversion motor 44 drives the first direction conversion disc 45 to rotate, so that the peanuts may move to be the vertical state along with the rotation of the first direction conversion disc 45. The third horizontal single-arm robot 11 drives the third longitudinal single-arm robot 12 to move in the horizontal direction, and the third longitudinal single-arm robot 12 drives the third pneumatic finger 13 to move in the vertical direction, so that the third pneumatic finger 13 is enabled to move horizontally and vertically.

When the first camera sensor 48 detects that the peanuts are suitable to be used as seeds and the heads of the peanuts are towards the moving direction which is opposite to the moving direction of the direction of the first conveyor belt 29, the second pneumatic finger 9 grabs the peanuts onto the third conveyor belt 41. The third camera sensor 50 detects the positions and states of the peanuts on the third conveyor belt 41 which move in the same direction as the first conveyor belt 29. After the third camera sensor 50 detects that the peanuts on the third conveyor belt 41 have reached the predetermined position, the data is transmitted to the controller. The peanuts may fall longitudinally into the groove of the second direction conversion disc 47, and the second direction conversion motor 46 is controlled to drive the second direction conversion disc 47 to rotate, so that the peanuts may move to be the vertical state. The fourth horizontal single-arm robot 19 drives the sixth vertical single-arm robot 20 to move in the horizontal direction, and the sixth longitudinal single-arm robot 20 drives the sixth pneumatic finger 21 to move in the vertical direction, so that the sixth pneumatic finger 21 is enabled to move horizontally and vertically.
