The beads 49 completed in a spherical shape by a molding press or the like are charged into the reservoir 21 and the lower end of the reservoir, which is moved to the supply cylinder 24 through the curved pipe 25, is inclined so that the beads in the reservoir 21 may be inclined. 49 is naturally moved to the supply container 24 and the supply pipe 24 in the reservoir 21 by adjusting the size of the inlet of the curved tube 25 by adjusting the block 26 to open and close the opening of the curved tube 25 up and down. It is possible to freely adjust the amount of movement of the bead 49 is moved to).

Then, the bead 49 moved to the supply cylinder 24, as shown in Figs. 6-7, the cross head 31 through the spring 31 'connected to the lower center of the funnel shape by its own weight. The inner side of the cross head 31 is caught by the latching jaw 30 of the tip of the cross-head 31, the bead 49, at this time, the beads 49 in a row from the lower side of the supply cylinder 24 to the tip of the guide path 29 The cross head 31 is rotated forward and backward by a predetermined angle about the bending shaft 32 on one side, and is in contact with the circumference of the cam 39 arranged at the rear end of the first cam shaft 19. Rotating shaft 35, which is erected downwardly on one end, rotates at a constant period at a speed and rotation angle corresponding to rotation of cam 39 by the elasticity of spring 36 installed on the other end. A section intersected at one end of the connecting section 35 is reciprocated in conjunction with the rotation of the rotating section 35 while being reciprocated in the other section. The bending axis (33) cross head 31 is fixed by the top of the rotating shaft 33 which will be periodically normal and reverse rotation.

That is, when the sliding interval 38 is in contact with the center of the indentation portion 40 of the cam 39, the cross head 31 is rotated forward, the front head of the cross head 31 is rotated upward, the cross head 31 The bead 49 hanging on the tip of the guideway 29 of the guide plate 29 is positioned coaxially with the holes 44 'and 45' of the movable tables 44 and 45, and the sliding interval 38 is the cam. When contacting the normal circumference of (39), the cross head 31 is reversely reversed to the forward rotation so that the front end is inclined downward so that the bead 49 moves one step to its own weight to the next bead guide ( 29) is to be caught in the front end engaging jaw (30).

As described above, the pair of movable tables 44 and 45 are compressed and fixed to the bead 49 that is raised by the forward rotation of the cross head 31. The pair of movable tables 44 and 45 are eighth. As shown in FIGS. 10 to 10, the sliding interval 55 rotates about the axis by the rotation of the cam 54 arranged in front of the first cam shaft 19, and the lower end is flush with the sliding interval 55.

The lifting plate 43 as the lifting plate 43 fixed to the upper end of the vertical connection bar 50 is moved up and down while the vertical connection bar 50 connected to the lower end is rotated on one side of the horizontal connection bar 51 by vertical movement. The movable table 44, 45 in which the projections 48, 48 'are placed in the pair of inclined holes 47 and 47' formed in the c) is moved left and right.

That is, when the sliding interval 55 is in contact with the maximum radius of the cam 54, the lifting plate 43 rises to the maximum, and the projections of the movable tables 44 and 45 are driven by the inclined holes 47, 47 '. When the movable table 44 is extended to the lowest position and the movable table 44 reaches the maximum radius, and the sliding interval 55 is in contact with the minimum radius of the cam 54, the lifting plate 43 descends to the minimum and the movable table 44 is lowered. (45) projections are located at the top of the inclined holes (47) (47 ') so that the movable tables (44) and (45) are compressed to the minimum, so that the locking jaws at the tip of the front guideway (29) of the cross head (31) The beads hung in 30 are compressed between the holes 44 'and 45'.

In addition, the holes 44 'and 45' formed in the movable tables 44 and 45 have an inner circumference thereof as an inclined surface to widen the contact area with the beads, thereby preventing flow due to the rotation of the drill during drilling. It is.

As such, the bead 49 is fixed to the movable tables 44 and 45, and at the same time, the drill machine 57 on one side is advanced to start drilling the bead 49, as shown in FIG. 12B. Likewise, when the sliding interval 37 is in contact with the maximum radius of the cam 65 arranged at the tip of the second cam shaft 20, the drill machine 57 is advanced to the maximum and the drill is mounted on the drill machine 57 ( The tip of 95 is drilled to a position slightly below the center of the bead 49, and the drill machine 57 retracts to the maximum when the sliding interval 67 is in contact with the minimum radius of the cam 65. And the retraction of the drill machine 57 is naturally made by the elasticity of the spring 69 in the sliding interval (67).

In addition, after the drill machine 57 is moved forward, the drill machine 56 on the other side is advanced at a predetermined time interval to drill the remaining holes in the bead 49, thereby drilling a complete through hole. As shown in the figure, when the sliding interval 66 abuts against the maximum radius of the cam 64 arranged in front of the first camshaft 19, the drill machine 56 is advanced to the maximum and the drill machine 56 The tip of the mounted drill 94 is drilled to a position slightly past the center of the bead 49, and when the sliding interval 66 is in contact with the minimum radius of the cam 64, the drill machine 56 is The retraction to the maximum, the retraction of the drill machine 56 is naturally made by the elasticity of the spring 68 in the sliding section (66).
