It consists of a second driving unit 370 that moves the moving plate 360 laterally.

Here, the magnet body 310 is provided to adsorb metal foreign substances through magnetic force. The magnet body 310 is placed in a state accommodated in the cover 320 to facilitate separation of the adsorbed metal foreign substances.

That is, when the cover 320 is moved into the movable housing 100 by driving the first driving unit 400 while accommodating the magnet body 310, the metal of the selection object falling on the movable housing 100 Foreign matter is adsorbed to the cover 320 by the magnetic force of the magnet body 310, and after a certain amount of the selection object has fallen, the first driving unit 400 is driven again to remove the magnet body 310 and the cover 320. Move to the magnet housing (200).

Then, when the second driving unit 370 is driven to separate the magnet body 310 from the cover 320, the metal foreign matter adsorbed on the cover 320 no longer generates magnetic force and moves to the lower side of the first magnet housing 210. It falls.

In addition, air is sprayed toward the cover 320 through the spray nozzle unit 212 formed on the upper inner wall or side inner wall of the first magnet housing 210 to remove metal foreign substances that have not yet fallen from the cover 320. Separate it and let it fall.

Accordingly, the cover 320 and the magnet body 310 can be moved laterally between the movable housing 100 and the first magnet housing 210 by the first driving unit 400.

Of course, a through hole must be formed on the wall of the movable housing 100 that is located between the movable housing 100 and the first magnet housing 210 to partition them, so that the cover 320 can move, and the through hole must be formed in the cover ( 320) should be formed in a size with a certain distance from the outer surface.

Meanwhile, the second driving unit 370 is installed on the fixing bracket 350 and connected to the third moving plate 360 to horizontally move the third moving plate 360 under the control of the control unit 500. It is provided to move, and the third moving plate 360 is located close to the first moving plate 330 when accommodated in the magnet body 310 and the cover 320, and the magnet body 310 is positioned close to the cover 320. In a state where it is separated from 320, it moves toward the second moving plate 340 by the second driving unit 370 and is positioned close to the second moving plate 340.

That is, the first moving plate 330 and the third moving plate 360 are connected to a fixing bracket 350 so that the positions of the first moving plate 330 and the third moving plate 360 are fixed to each other, and the second moving plate 340 is provided with a second driving unit so that the position can be moved between them. It is connected to 370 and is positioned close to the first moving plate 330 when adsorbing metal foreign matter, and is positioned close to the third moving plate 360 when separating metal foreign matter.

In addition, the cover 320 that selectively accommodates the magnet body 310 is preferably formed of a non-magnetic material to adsorb or release metal foreign substances depending on whether the magnet body 310 is accommodated. For example, in the present invention, The cover 320 was made of synthetic resin.

In this way, when the cover 320 is made of a non-magnetic material, no residual magnetic flux remains when separated from the magnet body 310, making it easier to separate metallic foreign matter. However, if it is made of a magnetic material, residual magnetic flux remains and the metallic foreign matter remains. Problems that make separation difficult may arise.

Meanwhile, the control unit 500 controls the first driving unit 400 and the second driving unit 370 to operate the cover 320 when the adsorption unit 300 adsorbs metal foreign substances in the mobile housing 100. With the magnet body 310 accommodated in the cover, metal foreign matter is adsorbed to the outer surface of the cover 320, and when the metal foreign matter is discharged from the first magnet housing 210, the magnet body 310 is moved to the cover ( It is provided to release metal foreign substances adsorbed on the outer surface of the cover 320 after leaving the cover 320.

In addition, the control unit 500 controls the operation of the spray nozzle unit 212. When the magnet body 310 is completely separated from the cover 320, the spray nozzle unit 212 is driven for a set time to cover ( Metal foreign substances attached to 320) are removed through air spray.

Hereinafter, the operation process of the above-described adsorption unit will be described in more detail.
