Under initial condition, the inside at control seat 17 is contract to expansion plate 18 and two 19 contractions of magnetic path, if food detects nonconforming, then electro-magnet 16 does not switch on, unqualified food continues clockwise moving along with putting thing seat 5, after putting thing seat 5 and removing to the bottom, start the outside removal of expansion plate 18, make two 19 of magnetic path outwards stretch out, two 19 of magnetic path outwards stretch out the back, with the bottom put the first 15 homopolar repulsion of magnetic path on the thing seat 5, it is rotatory to promote bottom plate 14, nonconforming food slides down the inside of containing box two 8 along the bottom plate 14 of slope, realized that the automation is carried out the function of collecting with the unqualified food that detects.

Put thing seat 5 and move and dial 20 contacts behind the bottom to it is rotatory to dial board 20, dials board 20 and drives slide 21 and wedge 22 after rotatory and move to the right, and wedge 22 moves to the right back, and expansion plate 18 stretches out outward, makes two 19 of magnetic path outwards stretch out and with the bottom put a magnetic path 15 on the thing seat 5 and align, promotes bottom plate 14 rotatory, has realized putting thing seat 5 after removing to the bottom, bottom plate 14 autogiration's function.

Through the design of the reset torsion spring and the support spring, after the shifting plate 20 is rotated and reset, the wedge-shaped plate 22 can drive the expansion plate 18 to contract inwards.

After the object placing seat 5 moves to the rightmost side, the first magnetic block 15 is blocked by the baffle plate 23, time is provided for the detection of the food by the detector 9, and after the detection is finished, the baffle plate 23 is retracted, so that the object placing seat 5 can continue to move.

In the initial state, the baffle 23 extends outwards; put thing seat 5 after moving to the rightmost, be magnetic block 15 and baffle 23 contact earlier to extrusion baffle 23 is inwards moved, makes the extension spring by tensile energy storage, and at this in-process, the extension spring plays the cushioning effect to magnetic block 15 and the removal of putting thing seat 5, puts thing seat 5 and keeps roughly stable, makes things convenient for detector 9 to detect work.

According to lenz's law, the magnetic field of the induced current always hinders the change of the magnetic flux causing the induced current, in short, "to reject to stay", when the aluminum rod 26 moves in the magnetic ring 27, the movement of the aluminum rod 26 is hindered to be slow, the moving speed of the object placing seat 5 when rotating to the rightmost side is further slowed down, and the detection work of the detector 9 is facilitated.

The front, the back, the left, the right, the upper and the lower are all based on figure 1 in the attached drawings of the specification, according to the standard of the observation angle of a person, the side of the device facing an observer is defined as the front, the left side of the observer is defined as the left, and the like.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
