BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a component aligning apparatus according to an embodiment of the present invention. It is assumed that a component applied to the embodiment of the present invention is a component m shown in FIG.

FIG. 1 shows an entire part aligning apparatus according to an embodiment of the present invention.
It comprises a linear vibration feeder 2 and a chute 3. Most of the linear vibration feeder 2 is constructed in a known manner, but the trough 4 is connected to the base 5 by a pair of front and rear inclined plate springs 6, 7, and the bottom wall of the trough 4 has a movable core. 8 is fixed, and an electromagnet 9 is fixed on the base 5 with a gap formed therefrom. The whole linear vibration feeder 2 is supported on the ground by a coil spring 10. In the trough 4 there is provided an alignment device 11 according to the invention, which is clearly shown in FIG.

A second component aligning device 15 is provided on the chute 3 connected to the trough 4 with a gap therebetween. The trough 2 has a U-shaped cross section as shown in FIG.
1 is arranged on the ground by columns 13 and 14 inclining downward as shown in the figure.

The component alignment device 11 provided in the trough 4 of the linear vibration feeder 2 will be described. As shown in FIG. 2, a pair of band-shaped members 1
6, 17 are mounted with a gap 18 therebetween. The gap 18 has a C-shaped cross section. The upper end is smaller than the diameter of the head h of the component m, and the head h that protrudes the lead wires a and b downward is a band-shaped member. It is supported by 16 and 17 and is in a suspended posture. As shown in FIG. 4, a rectangular permanent magnet 20 is disposed parallel to the trough 4 below one of the band-shaped members 16.
Is fixed on top. The upstream edge of the guide plate 19 is formed as a taper 19a, and the downstream edge of the guide plate 19 is linearly extended as a straight edge 19b in parallel with the transfer direction by vibration.

Next, the second component aligning device 15 disposed in the chute 3 will be described. Shoot 3
As shown in the figure, a U-shaped trough 21 is provided, and a pair of band-shaped members 22 and 23 are fixed inside the trough 21 with a gap 24 in the same manner as the upstream linear vibration feeder 2. Reference numeral 24 denotes a shape similar to that of the component aligning device 4 on the upstream side. The component 24 is discharged from the discharge port of the linear vibration feeder 2, and maintains the posture of the component m that is aligned left and right with respect to the lead wires a and b. And receive it at its upstream end,
It slides on the belt-like members 22 and 23 by the action of gravity. However, as in the case of the component aligning device 11 on the upstream side, it takes a suspended posture, and as shown in FIG. The regulating plate 25 extending along the transfer direction is fixed so as to be located between the lead wires a and b.

The embodiment of the present invention is configured as described above. Next, the operation thereof will be described with reference to the drawings.

A vibrating parts feeder, for example, is connected to the upstream side of the linear vibrating feeder 2. Parts m are supplied one by one from this discharge end, and the troughs 4 although vibrations being transferred by the lead wires a, direction b as shown in Figure 4 is not fixed, for example, component m ₁ is transported side by side leads a, b substantially transfer direction . When this reaches the area of the permanent magnet 20, both the lead wires a and b receive an attractive force,
The lead wire closer to the permanent magnet 20, for example, the shorter lead wire a, receives a stronger attraction force and turns in the direction shown by the arrow to take a position on the right side in the traveling direction. The longer lead wire b also receives the attractive force, but is prevented from moving toward the permanent magnet 19 by the edge 19 a of the guide plate 19. Therefore, the gap 24 between the pair of band members 16 and 17
And is transferred to the side of the permanent magnet 20. As shown in FIG. 2, the shorter lead wire a is connected to the permanent magnet 20 and the longer lead wire b is connected to the guide plate. It is transferred by vibration while abutting on the edge 19b of the 19 or the movement toward the permanent magnet 20 side is regulated.

From the linear vibration feeder 2, right and left, that is, the left and right of the lead wires a and b are aligned and the vibration is directly transferred to the chute 3 side by vibration. In shoot 3,
Similarly, the head h is suspended from the pair of belt-like members 22 and 23, and slides by the action of gravity. In this process, the restriction plate 25 prevents the lead wires a and b from shifting to the other side. Eventually, the chute 3 can supply the lead wires a and b one by one with the right and left positions adjusted.

Although the embodiment of the present invention has been described above, the present invention is, of course, not limited to this, and various modifications can be made based on the technical idea of the present invention.

[0015] For example, in the above embodiments, component alignment apparatus 11 is provided on the linear vibratory feeder 2, which is the inner peripheral wall portion, to form a et linear track, with a bowl-shaped container It may be provided in the vibrating parts feeder.

In the above embodiment, the component linear vibration feeder 2 and the chute 3 are used to supply the components to the next process in the posture shown in FIG. You may make it supply directly to a next process from a discharge end.

In the above embodiment, the head of the part m has a cylindrical shape. However, the present invention is not limited to this, and may be a rectangular tube or a disk. Lead wire a,
Although b is curved in the illustrated example, it may be straight.

In the above embodiment, the component aligning device 11
In FIG. 4, the guide plate 19 has a flat plate shape having a tapered portion 19a as shown in FIG. 4. However, the guide plate 19 may not be provided with the tapered portion 19a, but may be linear along the transfer direction, such as 19b from the start end. . Alternatively, instead of such a flat plate shape, a wire shape may be used. Of course, in this case, it is desirable to use a non-magnetic material. Similarly, in the chute 3, the regulating plate 25 is erected on the bottom wall of the trough 21, but instead of the regulating plate 25 , the wire is stretched to this level in accordance with the level of the upper end portion. Is also good.
