[0010] In each of the above-described coil spring alignment devices, the separated coil spring is returned to the bottom of the alignment bowl, so that the coil spring returned to the bottom of the bowl is placed in the coil placed in the bowl. There is a problem that the spring is entangled with the spring again, and there is a problem that the alignment supply efficiency is very poor. In addition, since the separation container is incorporated in the center of the aligning device, the shape of the device is complicated, the compatibility of the bowl is restricted, and the cost of the device is increased. Further, since the separation container is arranged in the bowl, there is a problem that the number of coil springs stored in the bowl is limited to a small number.

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple and compact vibration-type article supply apparatus that can efficiently align and supply articles that are easily entangled or overlapped.

[0012]

In order to solve the above-mentioned problems, a vibrating article supply apparatus according to the present invention comprises an upper vibrating body and a lower vibrating body, which are vertically opposed to each other, connected by a leaf spring. A parts feeder body in which the vibrating body is torsionally vibrated by vibration generating means, and attached to the upper vibrating body,
A bowl provided with a spiral track on the inner peripheral surface, means for discharging the entangled or overlapped composite articles to the outside of the bowl in the middle of the track, and separation for separating the discharged composite articles into single articles The separating device is disposed on the outer peripheral side of the bowl, and a means for returning the separated single article to the truck of the bowl is provided at an upper end portion of the separating device, and the returning means is provided at an upper end of the bowl. Therefore, a configuration that is arranged at approximately the same height was adopted.

That is, the composite articles that are entangled or overlapped in the middle of the truck are discharged to the outside of the bowl, and the discharged composite articles are separated into single articles by the separating device and returned to the truck in the bowl, whereby the bowl is restored. The single article is prevented from being recombined with the article stored in the bowl bottom, so that the article can be efficiently aligned and supplied by itself. Further, since the separating device is arranged on the outer peripheral side of the bowl, and the return means provided at the upper end of the separating device is arranged at substantially the same height as the upper end of the bowl, the separating device and the parts feeder main body and the bowl are separated. By eliminating interference, the design of the entire article supply device can be made simple and compact, and the capacity of the bowl can be effectively utilized.

As shown in FIG. 3, the outer wall 17 of the narrow portion 14 is formed at a height that is approximately half the diameter of the coil spring 8 and is low.
Is located at a height of approximately the diameter of the coil spring 8 and is disposed horizontally with its tip facing the outer wall 17. This narrow part 14
The entangled coil springs 8 passing through the outer wall 17 are vertically overlapped by centrifugal force caused by the torsional vibration of the bowl 6, and the center of gravity is higher than the upper end of the outer wall 17. Therefore, only the tangled coil spring 8 is connected to the outer wall 17 by the air nozzle 16.
And is discharged to the charging passage 10 outside.

As shown by an arrow in FIG. 4A, the entangled coil spring 8 discharged into the input passage 10 has a cylindrical input pipe 1 whose tip projects from the inner wall of the separation container 9.
8 and fall to the bottom of the separation vessel 9. This separation container 9
A rotary disk 20 driven by a motor 19 is provided at the bottom of the disk. The upper surface of the rotating disk 20 is formed in a concave shape, and a blade 21 is attached. A projection plate 22 is attached to the lower portion of the inner wall of the separation container 9.
The entangled coil spring 8 that has fallen into the separation container 9 is
The blade 21 is bounced off and stretched or bent, and the entanglement is removed.

The rotating disk 20 is rotating clockwise as indicated by the arrow in FIG. The projecting amount of the tip of the input pipe 18 from the inner wall of the separation container 9 is formed large on the side facing the rotation of the rotary disk 20, and the entangled coil spring 8 rebounded by the blade 21 returns into the input pipe 18. Is prevented. The protruding plate 22 is attached at a position 90 degrees counterclockwise away from the tip end of the input pipe 18 so as to be inclined upward toward the input pipe 18, and the entangled coil spring 8 to be bounced off is connected to the input pipe 18. To prevent it from hitting the tip.

Each of the coil springs 8 that have been entangled becomes lighter, and the spring elasticity restrained by the entanglement recovers. Track 1
Returned to 2.

As shown in FIGS. 1 and 2, a top plate 25 having a downward flange 24 at the upper end of the separation container 9 and projecting above the track 12 downstream of the narrow portion 14 is provided. Installed. A gap is provided between the overhang portion 26 of the top plate 25 and the upper end of the separation container 9 so that the coil spring 8 can protrude to the lower surface side of the overhang portion 26. The coil spring 8 protruding from the gap is returned onto the truck 12 from the downward discharge port 23 surrounded by the overhang portion 26 and the flange 24, and the single coil spring 8 has passed through the second narrow portion 14. At the same time, it is transported to the third narrow portion 15. Note that a shielding plate 27 is attached to a gap between the separation container 9 and the bowl 6 below the overhang portion 26 so that the coil spring 8 does not fall outside.

An air supply port 28 is provided below the rotating disk 20 of the separation container 9. When a coil spring having a small wire diameter and a small spring constant is separated, air is supplied from the air supply port 28, and the supplied air is blown into the separation container 9 from a gap on the outer periphery of the rotating disk 20 and separated. These coil springs are discharged from the discharge port 23.

The third narrow portion 15 is provided with an air nozzle 29 for sorting and returning the coil springs 8 to the bottom of the bowl 6 when they are conveyed. As shown in FIG. 5, a connecting track member 30 is attached to the narrow portion 15, and the air nozzle 29 is disposed in a groove 31 provided on the upper surface of the outer wall of the connecting track member 30, and is slightly smaller than the diameter of the coil spring 8. At a higher position toward the inner circumference. Therefore, as described above, the entangled coil spring 8 is vertically overlapped by the centrifugal force, and only the tall coil spring 8 is blown down to the bottom of the bowl 6 by the air nozzle 29.

The coil spring 8 having passed through the third narrow portion 15 is aligned and supplied from the outlet 32 of the truck 12 to a device in the next step.

FIG. 6 shows a second embodiment. This vibrating article supply apparatus also aligns and supplies the coil spring 8, and the configuration of the parts feeder main body and the separation apparatus is the same as that of the first embodiment, and only the shape of the alignment bowl 33 is partially different. The bowl 33 is provided with three narrow portions 35, 36, and 37 in the middle of a truck 34, and on the outer peripheral side thereof,
A branch track 38 is provided downstream of the second narrow portion 36 and merges with the track 34.

The top plate 25 of the separation container 8 is mounted so as to protrude above the branching track 38, is discharged to the charging passage 10 by the air nozzle 16, and is separated from the coil spring 8 by the separation container 9. It is returned on the branch track 38. Coil spring 8 returned on branch track 38
Joins with the coil spring 8 conveyed on the track 34, and, like the first embodiment, the air nozzle 29 arranged in the groove 31 of the connecting track member 30 attached to the third narrow portion 37. Screened, exit 39 of truck 34
