動作が開始されるまで停止することになる。 Now, when the insertion into the predetermined position is completed, the movable table 2 returns to the origin position of the orthogonal coordinate system. The work guide section 8 of the stock section 5 and the chute 20 of the alignment and supply section are aligned vertically. At this time, the detection unit 2 located above the stock section 5
1, when it is detected that the stock number of the retaining rings has decreased by a certain amount, the chuck 18 of the aligning and feeding device 4 is closed and the chuck 19 is opened, and a certain amount of the retaining rings between them is reduced by a certain amount. 5. When the supply is complete, chuck 19 is closed and chuck 18 is opened. At the same time, the moving platform 2
It moves to the first insertion position and stops until the next insertion operation starts.
一方、ストツク数がある一定量減じていない場
合、止め輪の供給は、行なわないで、一番最初に
挿入を行なう位置へ移動する。 On the other hand, if the stock number has not been reduced by a certain amount, the retaining ring is not supplied and is moved to the position where it will be inserted first.

１図参照）。 Next, the operation of inserting the retaining ring 29 into the shaft 25 will be explained. When the drive unit 9 rotates, the first
The second and third cams 10, 11, and 12 rotate, and the first, second, and third levers 13, 14, and 15 move along the cam surfaces. By the movement of these first, second, and third levers 13, 14, and 15, the slider 30 of the escape section 6 and the protruding rod 2 of the head section 7 are moved.
4. The jig 29 moves as shown in FIGS. 9 to 18.
That is, the slider 30 moves forward in the direction of arrow u,
A retaining ring 29 is supplied to the jig 21. At this time, the protruding rod 24 descends very close to the slider 30 (see FIG. 11). Next, the jig 21 is raised a little and the retaining ring 29 is hooked onto the jig 21 and fixed (see FIG. 12). When the slider 30 retreats,
The protruding rod 24 descends, and the retaining ring 29 is pushed down along the tapered jig 21 whose area becomes larger as it goes downward, thereby enlarging the inner diameter (see FIGS. 13 and 14). In this state, the protruding rod 24 and jig 21 are
They descend as one to a predetermined height (see Figure 15). Next, only the jig 21 rises a little further,
The retaining ring 29 is removed from the jig 21 and the protruding rod 24
It is pressed down by the lower end of the holder, and is inserted and fixed at a predetermined height (see Fig. 16). Subsequently, the protruding rod 24 also rises, and the protruding rod 24 and jig 21
Return to the starting position (see Figures 17 and 18). At this time, the slider 30 moves forward and the retaining ring 2 is attached to the jig 21.
Supply 9. This position is the regular position (first
(See Figure 1).
