It is constantly urged to the device 6 side.

Next, the operation of the clip guide device 6 according to the present invention will be described.

First, a method for loading the clip 7 into the clip supply device 8 will be described with reference to FIGS. 7 (a), (b), and (c). In a state where the clip 7 is not even loaded on the guide rail 16, The member 17 is located near the guide device, and the pusher member 17 is still attached to the guide rail 16 as shown in FIG.
As shown in (a), the clip 7 is sequentially dropped from the supply port 21 opening to the metal fitting 20. The dropped clip 7 is temporarily stopped at the stopper 22, but if the clip 7 is forcibly pushed down by hand, the clip 7 will open the stopper 22 and pass through it, and the vertical direction of the guide rail 16 will pass. It falls along the rail member 16a, contacts the both pins 30, 30 of the pusher member 17 and stops as shown in FIG. 7 (b). Thus, when a plurality of clips 7 ... Are loaded above the pusher member 17 and the pusher member 17 is pushed up with its pull-back pins 27, 27 as shown in FIG. 7 (c), the clips 7 ... It is moved upward by 30, 30, but the last clip is the stopper 22.
It comes into contact with and is prevented from coming off upward. Then, when the pusher member 17 is pulled up with an even stronger force, the pins 30, 30 of the pusher member 17 spread out against the leaf springs 29, 29, and the clips 7 ... At this time, the pins 30 and 3
Since the inclined surfaces 30a and 30a are formed on the pin 0 as described above, the clips 7 of the pins 30 and 30 can be easily loaded. In this way, after the pins 30, 30 have loaded all the clips 7 ..., When the pusher member 17 is released, the pusher member 17 is moved by the spring force of the constant output spring 31 so that the pin 30 has the rear end of the clip. Engages the edge and urges the clips 7 ... To the clip guide device 6 side.

Thus, the clips 7 ... Can be loaded into the clip supply device 8 very easily without removing the pusher member 17 from the guide rail 16. Further, the pusher member 17 is surely guided along the curved portion of the guide rail 16 via the rotatable rail guide pins 26 that are fitted to both end edges of the horizontal rail member 16b of the guide rail 16, and the constant output spring 31 is provided. Horizontal rail member 16b of the guide rail 16
Since it is arranged on the outer peripheral surface of the curved portion, the pusher member 17 can be moved smoothly. Further, since the guide rail 16 constituting the clip supply device 8 is bent in an L-shape and attached compactly, it does not hinder the work in a narrow place.

Then, the clip 7 loaded in the clip supply device 8 ...
Is a pusher member 1 biased by a constant output spring 31.
By the action of 7, the clip guide device 6 as shown in FIG.
One by one is sent from the passage 10 into the ejection passage 9. Then, the clip 7 sent into the launch passage 9 is biased in one direction (counterclockwise) by the presser spring 13 so that the edge of the inclined guide surface 11a of the clip guide piece 11 projects between both leg pieces of the clip. By doing so, the clip 7 is held at the illustrated position (striking position), so that the clip 7 does not drop before being driven by the driver. At this time, since the inclined guide surface 11a of the clip guide piece 11 projects between both leg pieces on the one end side of the clip 7, the position and posture of the clip 7 in the drive passage 9 are stable, and the clip guide piece 11 is inclined. It does not hinder the driving work.

Thus, the top of the clip 7 supplied and held at the striking position within the launch passage 9 is pressed by the driver 3 which is moved downward by the compressed air, and the clip 7 is moved downward while expanding the clip guide piece. It is attached to a predetermined part. Then, after the clip 7 has been hammered out of the hammering passage 9, the driver 3 moves up and the next clip 7 waiting in the hammer passage 10 is supplied and held at the striking position in the hammering passage 9 by the pusher member 17, The same action is repeated.

(Effect of the Invention) As is apparent from the above description, according to the present invention, the pusher member is mounted via the rail guide pins fitted to both end edges of the horizontal rail member of the guide rail, and the pusher member is attached to the elastic member. A pulling means having a urging and biasing clip engaging member and one end fixed to the pusher member is arranged such that the middle part thereof is along the outer periphery of the curved portion of the horizontal rail member of the guide rail, and the vertical direction of the guide rail. Since the rail member is provided with a stopper to prevent the clip loaded in the rail member from being pulled out, the clip can be loaded without pulling out the pusher member from the guide rail, and it is easy to load the clip and ensure the movement of the pusher member. In addition, it is possible to achieve smoothness, and it is possible to obtain an effect that a clip mounting operation can be performed in a narrow place.
