And then, when making part objective table 30 planes move and tilt, air gun 22 is also moved on the plane, and the direction of change jet 22b, thereby when becoming the state of Fig. 8 (c), air W1 just can blow in the recess 50Bd.
Like this, air gun 22, even if for having darker recess 50Bd, the part that bottom surface sections 50Bc side diminishes also can be to all part blow air W1 except its bottom surface sections 50Bc.
The control device 11 of Fig. 1 can be to move the plane of air gun 22 and the change of the direction of jet 22b, moves with the plane that keeps platform 30 and the mode of carrying out synchronously that tilts is controlled.
In addition, control device 11 after the blowing of the air W1 of part 50 grades (below, be also referred to as " dedusting ") finished, in the stipulated time of predesignating, for example in 10 seconds (s), continues the action of suction device 18.
Thus, can prevent that the dust removed from part 50 grades is once more attached on the part 50.
As mentioned above, as shown in Figure 1, the sidewall 12a of dirt pocket 12 etc. are connected with supply unit 20, can be charged.
And, control device 11, during to blow air W1 such as parts 50 (during dedusting), the logical electric current of going up such as oppose side wall 12a makes it charged.
Therefore, can with remove from part 50 grades, and charged dust, be adsorbed on the sidewall 12a etc.
Thus, can prevent reliably further that the dust removed from part 50 grades is once more attached on the part 50.
As mentioned above, keep platform 30 to move on the plane.
In addition, owing to keep the part objective table 30a of platform 30 tiltably to be constituted, therefore when part 50 grades during for three-dimensional shape, be when having the shape of concavo-convex complexity, for part 50 grades except with contacted of part objective table 30a all faces, can blow air.
Thus, according to dust arrester 10, can remove shape fully, have the foreign matter on the part of shape of concavo-convex complexity attached to solid.
In addition, the injection direction of air is moved and changes on the plane of synchronously carrying out air gun 22 owing to can move with the plane that keeps platform 30 and tilt, even if therefore for example have under the situation of darker recess in part 50 grades, also can adjust the position and the injection direction that keep platform 30 and air gun 22, so that can be to the inside of this recess blow air.
In addition, because air gun 22 discontinuous injection airs, therefore the air that blows on part 50 grades becomes shock wave.
Therefore, can remove effectively attached to the dust on part 50 grades.
In addition, because suction device 18 is constituted as after dedusting finishes, continue action in the stipulated time of predesignating, therefore the dust that can will swim in dirt pocket 12 after dedusting finishes is discharged from dirt pocket 12.
Thus, can prevent reliably that the dust removed from part 50 grades is once more attached on the part.
And then, owing to become charged formations such as when dedusting, making sidewall 12a, charged dust is adsorbed on the sidewall 12a etc.
Thus, can prevent reliably further that the dust removed from part 50 grades is once more attached on the part.
