Air is supplied by the operation of the supply hose 25, and the set screw 1 that has fallen into the supply hose 25 is supplied to a working unit (not shown).

The direction imparting means has a driving section, and this driving section has a shaft section 21f of the rotating annular member 21, as shown in FIGS. 2 to 4. This shaft portion 21f is rotatably held by the base plate 3, and a pinion 32 is fixed to one end of this shaft portion 21f. This pinion 32 is engaged with a rack 33 that is connected to and moves with the piston rod 30a of the second air cylinder 30, and this rack 33 directly reciprocates along a rack guide 34, moving the pinion 32 forward and backward every half turn. It is configured to rotate. This rack 33
A lever 42 is fixed to protrude downward, and this lever 42 is configured to pass through the side of a disc 37, which will be described later. The lever 42
When the rack 33 is at its most advanced position, the forward end of the lever 42 stops directly above the axis of the cylindrical reversing member 22, and the lever 42 contacts a pin 38, which will be described later, to move the cylindrical reversing member 22 to the rack 33. The pinion 32 is configured to rotate the motor by a rotation angle or more. Further, an arm 35 is fixed to the shaft portion 21f, and this arm 35
is configured so that the rotation angle of the rotating annular member 21 is regulated by contacting the reversing positioning members 36a and 36b fixed to the base plate 3.

On the other hand, the cylindrical reversing member 22 has a shaft portion 22b, and is configured to protrude rearward from the shaft portion 21f. A disc 37 is fixed to this shaft portion 22b, and recesses 37a, 37a are formed on the outer periphery of the disc 37 on a straight line, and the disc 37 is guided into the recesses 37a, 37a. Compression springs 41, 41 are attached to the guide plate 39.
The ball 4 is elastically biased and arranged by

a, 39a, and is configured to be retractable when the disc 37 rotates. Further, pins 38, 38 are implanted in the disk 37 so as to be located on the diameter thereof and protrude forward, and these pins 38, 38 are connected to the determination portion 21b by the desired set screw 1.
When the pinion 32 is fitted into the rotary annular member 21 and the cylindrical reversing member 22, the pinion 32 rotates by half a rotation. Further, the pin 38,
When 38 rotates half a turn, it reaches the movement path of the lever 42 and comes into contact with the pin 38 just before the lever 42 reaches the most forward position, and when the lever 42 reaches the position, the rack 33 moves linearly. Since the distance is longer than the parallel movement distance of the circularly moving pin 38, the lever 42 presses the pin 38, and together with the disk 37, the cylindrical reversing member 22 is rotated slightly ahead of the rotating annular member 21. It is configured.

In the rod-shaped component orientation device, as shown in FIGS. 5 and 6, the set screws 1 are separated one by one through the passage 20a of the outer ring main body 20 and the guide path 21a of the rotating annular member 21. It is supplied to the guide path 22a of the cylindrical reversing member 22. At this time, if the set screw 1 has its recess facing upward, only the rotating annular member 21 rotates as shown in FIG. Then, the set screw 1 falls to the supply hose 25 with the recess facing upward. Thereafter, air is supplied from the air hole 23c, and the set screw 1 is supplied to the working unit.

When the set screw 1 is positioned with its recess facing downward as shown in FIG. 9, the determining portion 21b of the rotating annular member 21 fits into the recess. In this state, when the rotating annular member 21 rotates, the set screw 1
Since the cylindrical reversing member 22 rotates together, the cylindrical reversing member 22 also rotates. When the rotating annular member 21 rotates by a predetermined angle,
The guide path 21a communicates with the drop hole 23a. At this time, the set screw 1 is caught in the edge of the rotating annular member 21 and the edge of the cylindrical reversing member 22 and does not fall, but the lever 42 that moves together with the rack 33 that rotates the rotating annular member 21 is rotated. It engages with a pin 38 implanted in the plate 37. Therefore, the disk 37 rotates slightly against the elastically biased ball 40. Therefore, only the cylindrical reversing member 22 rotates, the locking of the set screw 1 is completely released, and the set screw 1 falls to the supply hose 25. after that,
Air is supplied and the rod-shaped part is supplied to a predetermined position.

In addition, although the embodiment describes only a rod-shaped component having a recess, it is possible to correspond to a rod-shaped component having a protrusion as shown in FIG. 10 by configuring the determining section 21b to have a recess as shown in FIG. 11. It is something that can be done.

As explained above, the present invention provides a recess or protrusion determining section on the rotating annular member that rotates around the outer periphery of the cylindrical reversing member, and also attaches a pinion integrally to the rotating annular member, and reciprocates the rotating annular member so as to mesh with the pinion. A flexible rack is arranged, a lever is attached to this rack, and a disk that rotates together with the rack is attached to the cylindrical reversing member, and a pin is installed in this disk to slightly rotate the disk. Therefore, by providing a protrusion or a recess in the determination section, it is possible to provide a device that can easily handle both rod-shaped parts having a recess and rod-shaped parts having a projection. When the rod-shaped part fits into the determination part and the rotating annular member and the cylindrical reversing member rotate together, the jamming between the rod-shaped part and the rotating annular member and the cylindrical reversing member is completely released and the rod-shaped part is reliably formed. There are advantages such as being able to supply parts to predetermined positions.
