[0028] To remove metal and non-metal debris from the material being transported by conveyor 1, refer to Figure 1 、 Figure 2 and Figure 4 The present application provides a foreign body removal device for a belt conveyor 1, comprising a first CCD camera 2 for photographing and detecting materials on the conveyor 1, an iron remover 3, a manipulator 4 for removing non-metallic foreign bodies on the conveyor 1, and a controller 5; the first CCD camera 2, the iron remover 3, and the manipulator 4 are arranged in sequence along the conveying direction of the conveyor 1, and the iron remover 3 is located above the conveyor 1; the first CCD camera 2 is connected to the signal input end of the controller 5, and the signal output end of the controller 5 is electrically connected to the iron remover 3 and the manipulator 4 respectively.

[0029] During operation, the belt conveyor 1 runs, conveying the material along the conveying direction, so that the material passes through the first CCD camera 2, the iron remover 3 and the manipulator 4 in sequence. The first CCD camera 2 continuously takes pictures of the passing material and uses its own image processing software to analyze the pictures, thereby analyzing and identifying the type, location and other information of the material conveyed by the conveyor 1, and transmitting the relevant information to the controller 5. The controller 5 receives the input instructions;

[0030] When the first CCD camera 2 detects the presence of metal foreign matter on the conveyor 1, the controller 5 controls the iron remover 3 to accelerate from the idle state to the working state (Note: in the idle state, the iron remover 3 runs at a slower speed to reduce the power consumption of the iron remover 3, thereby reducing its power consumption and reducing the cost of using the equipment. In some specific embodiments, when the first CCD camera 2 does not detect metal foreign matter, the iron remover 3 is in the closed state. When the first CCD camera 2 detects metal foreign matter, the controller 5 controls the iron remover 3 to work again).

[0031] When the first CCD camera 2 detects the presence of non-metallic foreign matter on the conveyor 1, the controller 5 controls the manipulator 4 to move, grab the foreign matter from the conveyor belt, and discard it outside the conveyor 1, thereby achieving the purpose of removing the non-metallic foreign matter.

[0032] In this embodiment, the iron remover 3 includes a frame 31, a running belt 32, a roller 33, a motor 34, and an electromagnet 35; the frame 31 is arranged perpendicular to the conveying direction of the conveyor 1, and the running belt 32 is installed on the frame 31 through the roller 33. There are two rollers 33, which are rotatably installed at both ends of the frame 31. One of the rollers 33 is driven to rotate by the motor 34 installed on the frame 31, so that the running belt 32 is driven to rotate by the motor 34; an electromagnet 35 is provided between the two rollers 33, and the bottom of the electromagnet 35 is in contact with the running belt 32. When working, the electromagnet 35 is energized to generate magnetism, which will adsorb the metal passing under it to the running belt 32, and then the metal debris adsorbed will be transported to the side of the conveyor 1 through the rotation of the running belt 32. It can be imagined that because the roller 33 itself does not have magnetism, when the adsorbed metal is transported to the roller 33, it automatically falls under the action of gravity.

[0033] In this embodiment, the electromagnet 35 and the motor 34 are respectively connected to the signal output end of the controller 5. In the idle state, the motor 34 is in a low-speed rotation state, and the electromagnet 35 is in a non-magnetic or low-magnetic state to reduce its energy consumption when idling.

[0034] In this embodiment, the running belt 32 is provided with shifting bars 36 at intervals, and the shifting bars 36 push the adsorbed metal debris to move, ensuring that the metal debris can be pushed to the side of the conveyor 1.

[0035] Optionally, the electromagnet 35 may also be a permanent magnet to reduce the power consumption of the iron remover 3 .

[0036] In this embodiment, the manipulator 4 includes a linear module 41, an electric telescopic rod 42, and an electric clamp 43; the linear module 41 is installed on the frame 31 of the iron remover 3 and is arranged perpendicular to the conveying direction of the conveyor 1. One end of the electric telescopic rod 42 is fixedly installed on the slider of the linear module 41, and the other end extends downward and is installed with the electric clamp 43.

[0037] During operation, the electric clamp 43 grabs the debris on the conveyor 1, and the electric telescopic rod 42 drives the electric clamp 43 to move up and down, thereby picking up the debris, and the linear module 41 drives the electric clamp 43 to move to the side of the conveyor 1, thereby removing the debris.

[0038] In some specific embodiments, a second CCD camera 6 is further provided between the iron remover 3 and the manipulator 4. The second CCD camera 6 has similar functions to the first CCD camera 2 and is used to take pictures and detect materials on the conveyor 1. When the material on the conveyor 1 passes through the iron remover 3, the second CCD camera 6 still detects the presence of metal foreign matter on the conveyor belt. The second CCD camera 6 transmits the relevant information to the controller 5. The controller 5 controls the manipulator 4 to directly remove the metal foreign matter based on the input signal.

[0039] In some embodiments, Figure 3 As shown, a debris guide plate 7 is provided on the frame 31 of the conveyor 1, and the debris guide plate 7 surrounds the side of the conveyor 1 to prevent fallen debris from falling onto the lower belt of the conveyor 1, thereby causing the problem of debris scratching the belt.

[0040] While various embodiments of the present invention have been described above, the above descriptions are illustrative and non-exhaustive, and are not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to existing technologies, or to enable others skilled in the art to understand the embodiments disclosed herein.
