BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail according to the embodiments of the invention shown in the drawings.

The component 1 is a shaft-shaped component having a circular cross section, is composed of a small-diameter portion 2 and a large-diameter portion 3, and has a holding recess 5 of a holding member 4.
It is supposed to be retained inside. This holding member 4
Is attached to a base plate 6 which is a stationary member, and an opening / closing member 7 which is a locking means is arranged in order to securely hold the shaft-shaped component 1 in the holding recess 5. The holding recess 5 is a vertically penetrating space having an arcuate portion 8 that matches the large-diameter portion 3, and a component outlet 9 thereof is opened and closed by a plate-like opening / closing member 7. This opening / closing member 7 is for moving back and forth,
Piston rod 1 of air cylinder 10 mounted on substrate 6
1 is connected to the opening / closing member 7. The lower end of each of the shaft-shaped components 1 in the holding recess 5 is received by the substrate 6.

A supply rod 12 is provided for receiving the shaft-shaped component 1 from the holding member 4 and supplying the shaft-shaped component 1 to a destination. A holding portion 13 is formed at the tip of the supply rod 12 so as to face the holding recess 5. The holding portion 13 is formed with an arcuate surface that matches the large diameter portion 3 of the shaft-shaped component 1, and this is the holding surface 14. An axis of the shaft-shaped component 1 when the shaft-shaped component 1 is held in the holding recess 5,
The arc portion 8 and the holding surface 1 are arranged so that the axis of the shaft-shaped component 1 when the shaft-shaped component 1 is held by the holding portion 13 becomes parallel.
4 relative positions are set.

The supply rod 12 is supported in a guide cylinder 15 so as to be movable back and forth, and is moved forward and backward by an air cylinder 16 connected to the guide cylinder 15. The substrate 6 is welded to the guide cylinder 16. Driving means 17 for moving the supply rod 12 in parallel is connected to the guide cylinder 15. The drive means 17 is an air cylinder fixed to the stationary member 18, and its advancing / retracting direction is the same as the axial direction of the shaft-shaped component 1 held by the holding portion 13.
Further, the advancing / retreating direction of the supply rod 12 is a direction orthogonal to the axis of the shaft-shaped component 1.

In order to firmly position the shaft-shaped component 1 on the holding portion 13, a suction means 19 is provided, and a magnet (permanent magnet) 19 is arranged behind the holding surface 14 as its specific structure. I am doing it. Instead of the permanent magnet, an electromagnet 20 as shown by a two-dot chain line may be used. In order to make the attraction force of the magnet 19 act on the shaft-shaped component 1 as strongly as possible, the supply rod 12 is made of a non-magnetic material such as aluminum or stainless steel. In addition, X in FIG.
-X is the axis of the shaft-shaped component 1.

A component supply pipe 21 extending from the parts feeder 21 is connected to the holding member 4. When the supply rod 12 advances to the target location, the shaft-shaped component 1 is supplied to the target location. There are various objects as the target location, and there are various cases such as a chuck hole at the center of a lathe and a receiving hole for parts. Here, the counterpart component 23 is fixed on the stationary member 18, and a receiving hole 24 is opened in the center thereof. In the state shown in FIG. 2, the supply rod 12 is advanced and the axis of the shaft-shaped component 1 is aligned with the axis of the receiving hole 24. Here, the air cylinder 17 operates to move the guide cylinder 15 downward. When pulled down, the supply rod 12 is translated in the axial direction of the shaft-shaped component 1, and the small diameter portion 2 is inserted into the receiving hole 24.
When the supply rod 12 is retracted from this inserted state, the attraction force of the magnet 19 acts on the shaft-shaped component 1, but only the shaft-shaped component 1 remains in the receiving hole 24, and the component supply is completed.

With the above structure, the shaft-shaped component 1 is firmly positioned in the holding recess 5 installed on the substrate 6,
In addition, the shaft-shaped component 1 held in the holding recess 5 is attached to the opening / closing member 7
Since the shaft-shaped component 1 is locked by the holding recess 5, the shaft-shaped component 1 is in a stable standby state. After that, when the locking function of the opening / closing member 7 is released, the holding portion 13 of the supply rod 12 moves into the holding recess 5
The shaft-shaped component 1 is reliably moved from the holding recess 5 to the holding portion 13 of the supply rod 12 because the shaft-shaped component 1 is opposed to the holding portion 13. The moving force of the shaft-shaped component 1 necessary for this transition is secured by the magnet 19 of the shaft-shaped component 1, and the shaft-shaped component 1 transferred to the holding portion 13 is firmly held by the supply rod 12 by this magnet 19. Therefore, the shaft-shaped component 1 surely moves from the holding member 4 installed on the stationary member to the holding portion 13 of the supply rod 12, and the holding portion 13 is firmly held by the supply rod 12 by the magnet 19. Then, the supply rod 12 advances and the shaft-shaped component 1 is supplied to the receiving hole 24 of the counterpart component 23. In this way, the shaft-shaped component 1 is accurately transferred to the holding portion 13 of the supply rod 12, and a highly reliable component supply function can be obtained.

Further, the axis line when the shaft-shaped component 1 is held in the holding recess 5 and the axis line when the shaft-shaped component 1 is held by the holding surface 14 are parallel to each other. 1 is a holding surface 1 of the supply rod 12 only by moving in parallel.
4, the axis line is not intentionally inclined during the transitional transition period of the shaft-shaped component 1, and the transitional behavior of the shaft-shaped component 1 is the simplest, and accurate component movement is executed. It

Next, the movement of the shaft-shaped component 1 shown in FIG. 5 will be described. This is different from the above-mentioned locking means 7 in the form of an opening / closing member, but here, the movement of the shaft-shaped component 1 is performed by a combination of the suction pressure and the ejection pressure of air. In the same figure (A), the vacuum of air is made to act on the shaft-shaped component 1 as shown by the arrow, and the shaft-shaped component 1 is held by the holding member 4. Therefore, the pressure space 25 is formed on the inner surface of the holding recess 5, and the air passage 26 is opened therein. From this state, when compressed air is sent to the pressure space 25 as shown by the arrow in FIG.
It is pushed out from and moved to the holding portion 13. During this transition, the air suction force acts on the pressure space 27 formed in the holding surface 14 as indicated by the arrow, so that a vacuum pressure acts on the shaft-shaped component 1 and is attracted to the holding surface 14.
