In the above configuration, when the fastener component supply switching device of the present invention is operated to convey the upper hooks 2a, the following procedure is performed.

First, as shown in FIGS. 6 and 7, one of the two solenoids 34a and 34b is
ON state only. Accordingly, the left side of the connecting rod 35 is tilted so as to retract toward the rear, and the rotating lever 33a is rotated counterclockwise about the shaft support 32a. At this time, the lower stopper 30a is biased by the spring 31a and tries to move toward the back, but since the convex portion 25a of the upper hook conveying member 25 is located closest to the front side,
The buckle 30a to the lower step 1 contacts the convex portion 25a and does not move toward the back. Therefore, the tip of the lower stopper 30a is located within the first guide groove 23b, and the upper hook 2
a... will not slide down into the second guide groove 26a. On the other hand, since the upper stopper 29 is pressed by the upper stopper pressing member 38 fixed to the piston rod 39 and is located closest to the front side, the protruding portions 2 at both ends of the upper stopper 29
9a and 29a are not located in the first guide groove 23b, and the leading upper hook 2a can slide down until it comes into contact with the lower stoppers 30a and 30b.

Next, as shown in FIGS. 8 and 9, the piston rod 39 is moved slightly toward the rear. As a result, the upper stopper pressing member 38 and the upper stopper 29 are separated, and the upper stopper 29 is urged by the spring 37 and moves on the upper stopper guide member 48 in the direction of the back force while being guided by the elongated hole 29b. As a result, the protrusions 29a and 29a at both ends of the upper stopper 29 are located within the first guide grooves 23b and 24b. On the other hand, the lower stopper 30a spring 31
a, and moves toward the back side while contacting the convex portion 25a of the upper hook conveying member 25. However, the lower stopper 3
Since the tip of 0a is still in the first guide groove 23b,
The upper hooks 2a... do not slide down the first guide a23b.

On the other hand, the lower stopper 30b comes into contact with the tip of the rotary lever 33b after moving slightly toward the rear, and therefore does not move further toward the rear.

Next, as shown in FIGS. 10 and 11, the piston rod 39 is further moved toward the rear.

As a result, the upper stopper 29 does not move, but is urged by the lower stopper 30a and the spring 31a and moves in the rear direction until it comes into contact with the flange of the pin 36a. Therefore, the lower stopper 30a completely leaves the first guide groove 23b, and the ten hook 2a located at the top slides down until it comes into contact with the side surface of the upper hook conveying member 25 located in the second guide a26a. . However, the second upper hook 2
Since the tip of the upper stopper 29 is located within the first guide groove 23b, the upper stopper 29 will not slide down.

After this, as shown in FIGS. 12 and 13, screws 1 to
The front door 39 is further moved toward the rear.

As a result, the upper hook conveying member 25 retreats to the rearmost part, and the tip of the upper hook conveying member 25 retreats from the confluence of the first guide groove 23b and the second guide groove 26a, so that the upper hook 2a located at the front will slide down into the second guide a26a.

Thereafter, the screws 1 to 39 move toward the front again, resulting in the state shown in FIG. 6. As a result, the tip of the lower stopper 30a is located in the first guide groove 23b again, the tip of the upper stopper 29 exits the first guide groove 23b, and the upper hook 2a in the second guide groove 26a.
... is pushed out by the upper hook conveying member 25 and is transferred to the upper processing section 4
9. Next, the lower hook 3 is conveyed from inside the lower hook hopper 7 via the lower hook guide rail 12 and the lower hook guide groove 50a onto the lower processing section 51 and is pressed.

On the other hand, when switching the hook to be pressed from the upper hook 2a to the upper hook 2b, the solenoids 34 and 2 are turned off.
The lower stopper 30a is placed in the first guide groove 23b in the F state.
is constantly intruding. On the other hand, solenoid 34
By turning on b, the lower stopper 30b moves forward and backward into the first guide groove 24b in conjunction with the piston rod 39, so the upper hooks 2b slide down one by one into the second guide groove 26a. It turns out. Thereby, the upper hook 2b is conveyed into the upper processing section 49 and is pressed with the lower hook 3. Therefore, when attaching two types of upper pouches 2a and 2b having the same lower hook 3 to the same clothing, etc., there is no need to attach and detach the upper hook hoppers 5 and 6 and the upper hook guide rails 8 and 9. Clothes can be easily attached with hooks.

Further, since the above-mentioned fastener component supply device can be operated without using air, it can be installed at any location.

Further, since the fastener component supply switching device and the main body portion 1 can be attached and detached using the snap lock 40, the fastener component supply switching device can be easily attached and detached.
