is inserted.

In the above alignment device, before starting work, Fig. 6a
As shown in FIG. 2, the second cylinder 24 is in the retracted state, and the rotary lever 19 is in contact with the stopper surface 22a of the stopper 20. In this state, stud 2
drop groove 9 of the shuttle plate 7 when is in the retracted position
When the shuttle plate 7 reaches the forward position, the stud 2 is located in the guide path 14 in the rotary plate 12, as shown in FIG. 6b. When the stud 2 is located in the drop groove 9, the photoelectric detection device 16 is activated, and when the stud 2 is detected, the sixth
Proximity switch 17 is advanced as shown in Figure c. At this time, when the proximity switch 17 detects the unthreaded portion of the stud 2, the second cylinder 24 is advanced to move the stopper 20 as shown in FIG. 6d. For this reason, the rotary lever 19, which was biased in the rotational direction by the rotary actuator 18,
The central shaft 13 and the rotating plate 12 are rotated 90 degrees,
As shown in FIG. 6e, the unthreaded portion of the stud 2 is positioned on the backward side, and the stud 2 is positioned in line with the extraction pipe 27. At the same time, air is supplied, and the stud 2 in the guideway 14 is discharged from the rotary plate 12 and is supplied to a desired position.

Thereafter, the rotary actuator 18 returns, but the rotary lever 19 comes into contact with the stopper surface 22b of the stopper 20 and stops at that position, and the guide path 14 of the rotary plate 12 and the communication pipe 6 communicate with each other and stop. do.

Next, when another stud 2 is fed into the guideway 14 in the opposite direction to that in the previous case, this is detected by the proximity switch 17. As a result, the rotary actuator 18 is driven again from the backward movement, and the rotary plate 12 is rotated in the opposite direction to that in the above case. As a result, the unthreaded portion of the stud 2 is similarly positioned on the retreating side, and the stud 2 is supplied to a predetermined position. Thereafter, the rotary actuator 18 moves back again and the rotary lever 19 comes into contact with the stopper 20 in preparation for the next operation.

As explained above, since the present invention is configured to stop the rotation of the rotary actuator at an intermediate position, it is possible to align and supply studs by simply rotating the rotary plate 90 degrees. It has the advantage of being able to handle extremely high-speed work. Further, the rotation direction of the rotating plate only needs to be controlled by controlling the drive of one cylinder or one rotary actuator.
There are also advantages such as an extremely simple control mechanism and the ability to provide a device equipped with an inexpensive control device.
