DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the embodiment shown in FIGS. 1 to 5 will be described. The part 1 to be treated here is composed of a shaft portion 2, a flange 3 and a welding projection formed on the flange (not shown). The projection projection is made of iron. The reciprocating supply rod 4 holds the bolt 1 at the tip thereof and advances to eliminate the holding force of the component at the target location, complete the component supply, and return to the original position again. Various methods such as a chuck mechanism and an electromagnet method are conceivable as a method of holding the component at the tip of the supply rod 4, but here, a permanent magnet type is exemplified.

That is, the supply rod 4 has a double structure of a hollow shaft 5 and an inner shaft 6 slidably inserted therein, and the entire supply rod 4 is housed in an outer cylinder 7. The cylinder 7 is firmly fixed to a stationary member 9 via a bracket 8. An air cylinder 10 is connected to an upper end of the outer cylinder 7, and a piston rod 11 thereof is fixed to the supply rod 4. A regulating pin 13 is fixed to the inner shaft 6 and protrudes to the outside through an elongated hole 14 in the stroke direction opened in the hollow shaft 5. The elastic force of the coil spring 15 inserted into the hollow shaft 5 acts on the inner shaft 6, whereby the regulating pin 13 hits the lower end of the elongated hole 14. In this state, the front end surfaces of the hollow shaft 5 and the inner shaft 6 form one plane so that the flange 3 can be in close contact as shown. An air cylinder 16 is fixed to a side surface of the outer cylinder 7, and a locking piece 18 attached to the piston rod 17 is provided.
Project into the outer cylinder 7 through an elongated hole 19 formed in the axial direction of the outer cylinder 7. The relative positions of the restricting pin 13 and the locking piece 18 are such that the restricting pin 13 stops immediately before the locking piece 18 when the supply rod 4 makes a stroke of a predetermined length. A magnet (permanent magnet) 20 is embedded at the tip of the inner shaft 6 and is covered with a cover plate 21.

[0007] A guide rail 22 is welded to the lower end of the outer cylinder 7 in a direction perpendicular to the stroke direction of the supply rod 4. This rail has a cross section as shown in FIG.
A slit 23 is provided in order to make the head hanging.
The mounting member 24 has a shape as shown in FIGS.
That is, it is a substantially U-shaped member in which a passage groove 27 in which one is an open part 25 and the other is a stopper part 26 is formed in a plate material. The mounting member 24 moves forward and backward,
The direction is perpendicular to the supply rod 4 and along the direction line in which the part enters. Therefore, the slit 23 and the passage groove 27 are aligned in a straight line as shown in FIG. An air cylinder 28 is provided for moving the mounting member 24 in the above-described direction. This is the outer cylinder 7
The piston rod 33 is fixed to the mounting member 24. In addition, a magnet (permanent magnet)
30 are provided. This is one in which a cover plate 32 is attached so as to be embedded in a holding piece 31 welded to the lower end of the outer cylinder 7. In order to more strongly apply the attraction force of the magnets 20 and 30, the peripheral members, namely, the inner shaft 6, the hollow shaft 5, the cover plate 21, the outer cylinder 7, the guide rail 2
2. It is appropriate that the holding piece 31, the cover plate 32 and the like use stainless steel which is a non-magnetic material.

The operation of this embodiment will be described. When the bolt 1 slides on the guide rail 22 by any method such as tilting or pushing, and comes close to the left end of the guide rail, the flange 3 is attracted by the magnets 20 and 30.
Slides on the upper surface of the mounting member 24 while the shaft portion 2 is
7, the bolt 1 moves to the left. Then, the shaft portion 2 comes into contact with the stopper portion 26 and the bolt 1 stops, and at the same time, the flange 3 is held in close contact with the lower end surface of the supply rod 4 as shown in FIG. Next, after the mounting member 24 is retracted to the left by the operation of the air cylinder 28, the supply rod 4
Is advanced, and the advance stroke is stopped when the shaft portion 2 enters a target location, for example, the accommodation hole 35 of the fixed electrode 34 in FIG. In this state, the restricting pin 13 is stopped immediately before the locking piece 18, and the displacement of the restricting pin 13,
Since it is transmitted to the inner shaft 6 and the magnet 20 is separated from the flange 3 as shown in FIG. 5, the attraction force on the flange 3 has substantially disappeared, and the bolt 1 is separated from the supply rod 4 and in the accommodation hole 35. The supply of parts is completed. The supply rod 4 retreats in the state of FIG. 5, and each cylinder sequentially performs the reverse operation to the above, and returns to the state of FIG.

Next, the embodiment shown in FIGS. 6 to 8 will be described. The component 36 handled here is a projection nut. The distal end of the guide tube 37 having a rectangular cross section is bifurcated and provided with protruding pieces 38, 38 on which the outer cylinder 3
9 is welded, and a magnet (permanent magnet) 41 is fixed to the end faces 40, 40 of the protruding pieces 38, 38 in a state where the magnet 41 is pressed. The magnet 41 is fitted into the hole of the thick plate 42, and cover plates 43, 43 are attached from the left and right.
It is pressed and fixed by a bolt 45 penetrating a bracket 44 welded to the outer cylinder 39. An air cylinder 46 is fixed to the upper end of the outer cylinder 39, and its piston rod serves as a supply rod 47.
The small diameter portion 48 penetrating the screw hole of the large diameter portion 49 is provided.
The extruding surface 50 is provided at the boundary between the two.

Since the mounting member and the method of moving it forward and backward are exactly the same as in the previous embodiment, the same reference numerals are used and the detailed description is omitted. The short arm member 29 is welded to the lower surface of the guide tube 37. The mounting member 24 moves forward and backward along the direction in which the nut 36 enters, that is, the left and right direction in FIG. The placement member 24 is shown in a two-dot chain line in FIG. 8, and shows the positional relationship with the protruding pieces 38.

Referring to the operation of this embodiment, FIG. 6 shows that the nut 38 is on the mounting member 24 and the magnet 4
1 is a state where temporary locking is achieved. When the supply rod 47 advances, the small diameter portion 48 penetrates through the screw hole of the nut 36 and the passage groove 27, and at the same time, the mounting member 24 is retracted rightward. When the pushing surface 50 of the supply rod 47 comes into contact with the upper surface of the nut 36, the nut 36 slides on the cover plate 43 while receiving the attractive force of the magnet 41, and is supplied to the target location while being held by the supply rod 47. .
