Since the upper end opening (1A) has a funnel shape as described above, the washer W is attached to the upper end opening (1A).
Guided to the approximate center of

[Bolt BT supply] The bolt BT slides down the bolt supply shooter (33) to form an annular ring of the bolt supporting means B.
It is supplied to the bolt support groove (8) of (6). The bolt support groove
(8) is provided with a notch (8A) on the opposite side in the direction of rotation of the ring (6) at the opening end as shown in FIG. Has been moved to. The bolt BT is suspended from the support groove (8) via a head.

[Washer Fitting] As described above, the washer W and the bolt BT are set in the washer assembling device C, and the washer W is assembled into the bolt BT. The process of assembling the washer will be described with reference to the developed view of FIG.
The bolt BT is supplied onto the upper end opening (1A) of (1), and when rotated 45 °, the bolt BT is supplied and suspended in the bolt supporting groove (8) of the ring (6) of the bolt supporting means B.

As shown in FIGS. 4 and 7, the bolt BT is supported by a positioning guide blade (34) which is a guide edge supported from the upper base (20) via a bracket (35) and a column (36). The ring cam (18) is pushed down to the innermost end of the support groove (8) of the ring (6) and rotated 90 °.
The outer cylinder (10) of the pressing means (9) of the bolt supporting means B
Is pushed down together with the piston (11), and the piston (11) presses the head of the bolt BT to fix the bolt BT. Further, the protruding cylinder (2) of the washer fitting device A is pushed up by the ring cam (19) together with the positioning rod (3), and FIG.
As shown at 0, the washer W on the upper end opening (1A) of the outer cylinder (1) is picked up by the tip (3A) of the positioning rod (3). At this time, the center of the washer W is made to coincide with the axis of the positioning rod (3) by the sharpened shape of the tip (3A), and the support groove (8) of the ring (6) of the bolt supporting means B is formed. It can be made to match the axis of the bolt BT pushed into the innermost end

In this way, the bolt BT and the washer W are accurately positioned, and the washer W of the washer fitting device A is projected while the washer W rotates to 165 °.
Is lifted further upward, and fitted to the bolt BT. The shaft of the bolt BT fits into the protruding cylinder (2), and the positioning rod (3) is pushed by the lower end of the bolt BT and protrudes into the protruding cylinder (2). . 1
At the 65 ° rotation position, the projecting cylinder (2) reaches the uppermost position, at which position one side of the washer W is supported by the inner rod (37A) of the washer holding fork (37) shown in FIG. 2) is lowered along the slope of the ring cam (19) by the urging force of the spring (4). If the bolt BT is not supplied to the support groove (8) of the ring (6) of the bolt support means B due to an operation error, at this time, the operation shown in FIG.
As shown in (1), only the washer W is discharged by the laundered washer discharge chute (38). The washer discharge chute (38) is biased by a spring toward the inner rod (37A) of the washer holding fork (37) via a handle.

In the normal state, when the protruding cylinder (2) is lowered, the washer W fitted into the bolt BT has one side as shown in FIG.
7A), and the other side has a discharge chute (3
Backed by 8). Then, at the 195 ° rotation position, the washer W is supported on both sides by the inner rod (37A) and the outer rod (37B) of the holding fork (37), and then by the bent shape of the inner rod (37A) and the outer rod (37B). Guided and thin part (7) of ring (6) of bolt support means B
Is moved outward together with the bolt BT so that the entire washer W enters the area indicated by the arrow B. Further, the washer W is lifted upward by the slopes of the inner rod (37A) and the outer rod (37B), and at a rotational position of 210 °. The washer W is fitted deeply into the bolt BT so as not to come off the bolt BT during discharge.

[Bolt Discharge] The bolt BT into which the washer W is incorporated as described above is transferred from the holding fork (37) to the bolt discharge shooter (39).
The discharge shooter (39) is suspended between the side edges (39A, 39A), which are the support edges, via the head and the washer W, and slides down. Side edges (39A, 39A) of the outlet shooter (39) width W ₁ between but is set to be larger than the diameter of the small shaft portion than the diameter of the head of the bolt BT, the end of the discharge shooter (39) width W ₂ between the both side edges (39B, 39B) in front bolt BT
Is larger than the diameter of the washer W, and if the washer W is not fitted into the bolt BT due to an operation error, the bolt BT in which the washer W was not fitted is sieved off at this point. , Discharge shooter
Only the bolt BT with the washer W installed reaches the end of (39).

[0016]

As described above, according to the present invention, when the washer is mounted on the bolt, the positioning is performed extremely accurately, and the washer can be easily and reliably mounted on the bolt.
