(Operation of parts alignment device)
FIG. 7 is a diagram for explaining the operation of the component aligning apparatus 3 shown in FIG. 8A is an enlarged view of a Q portion in FIG. 7A, and FIG. 8B is an enlarged view of an R portion in FIG. 7B. FIG. 9 is an enlarged view for explaining the state of the S part in FIG. FIG. 10 is an enlarged view for explaining the state of the T portion in FIG.

  In the component aligning device 3, when a plurality of components 2 are supplied onto the disk 11 through the opening 12 b, the component 2 moves along the alignment groove 12 a by the frictional force between the upper surface of the disk 11 and the component 2. The disk 11 rotates eccentrically so as to move and align. Specifically, in order to prevent the part 2 from being caught in the alignment groove 12a, the motor 14 rotates forward and backward so that the disk 11 rotates eccentrically in the forward direction and the reverse direction.

  When the disk 11 rotates eccentrically in the forward direction (clockwise direction (clockwise direction in FIG. 7)), for example, as shown in FIG. 7 (A), the component 2 is moved from the base end side of the alignment groove 12a. Moving toward the front end side while repeatedly hitting the side surface of the alignment groove 12a, alignment is performed. The single component 2 that has moved to the tip of the alignment groove 12a enters the fourth groove portion 12s. Thereafter, when the disk 11 rotates eccentrically in the reverse direction (counterclockwise in FIG. 7), as shown in FIG. 7 (B), other than the one part 2 contained in the fourth groove 12s. The component 2 moves from the distal end side to the proximal end side of the alignment groove 12a.

  It should be noted that a force in a substantially lower left direction acts on the component 2 that is in contact with the side surface 12k when the disk 11 is eccentrically oscillated and rotated in the positive direction due to friction with the upper surface of the disk 11, and therefore the side surface 12k. The component 2 abutting on moves to the lower right direction along the side surface 12k and is guided to the alignment groove 12a.

  As shown in FIG. 8A, the component 2 that has entered the fourth groove portion 12s when the disk 11 rotates eccentrically in the forward direction contacts the rear side surface of the fourth groove portion 12s. Thereafter, when the disk 11 rotates eccentrically in the reverse direction, the component 2 in the fourth groove portion 12s contacts the front side surface and the right side surface of the fourth groove portion 12s as shown in FIG. 8B. That is, the component 2 is accurately positioned in the fourth groove portion 12s.
