DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIGS. 1 to 5 show a first embodiment.
As shown in FIGS. 1 and 2, this vibrating article supply device includes a parts feeder body composed of an upper vibrating body 2 and a lower vibrating body 3 which are vertically connected by a leaf spring 1 via an anti-vibration rubber 4. A cylindrical alignment bowl 6 is attached to the base 5 at the center of the upper surface of the upper vibrating body 2 with bolts 7. This article supply apparatus is for arranging and supplying a coil spring 8, and a separation apparatus having a cylindrical separation container 9 is attached to a column 11 fixed to the base 5 on the outer peripheral side of the alignment bowl 6. I have.

Although not shown, the upper vibrating body 2 and the lower vibrating body 3 each incorporate a movable iron core and an electromagnet. By connecting an AC power source to the electromagnets, the bowl 6 is moved together with the upper vibrating body 2. Vibrates torsionally. Due to this torsional vibration, the coil spring 8 thrown into the bottom of the bowl 6 is transported along a spiral track 12 provided on the inner peripheral surface of the bowl 6.

In the middle of the track 12, three narrow portions 13, 14, 15 are provided at three places. The coil spring 8 conveyed on the track 12 by the torsional vibration is formed by the first narrow portion 13. It is arranged in substantially one line including the entangled coil spring 8 and is conveyed to the second narrow portion 14.

An air nozzle 16 is arranged on the inner peripheral side of the second narrow portion 14, and a charging passage 10 to the separation container 9 is arranged on the outer peripheral side thereof. 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 entangled coil spring 8 is selectively blown out beyond the outer wall 17 by the injection of the air nozzle 16 and is discharged to the charging passage 10.

As shown by the arrow in FIG. 4A, the entangled coil spring 8 discharged into the charging passage 10 has a cylindrical charging pipe 1 whose tip projects from the inner wall of the separation vessel 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. Therefore, the coil springs 8 jump up high as shown by arrows in FIG. 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 selecting the tangled coil springs 8 and returning them 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 and is selectively discharged to the charging passage 10 by the air nozzle 16 and separated by the separation container 9. Is returned on this branch track 38. The coil spring 8 returned on the branch track 38 is the coil spring 8 conveyed on the track 34.
And the third narrow portion 37 as in the first embodiment.
Are separated by an air nozzle 29 arranged in a groove 31 of a connection track member 30 attached to the apparatus, and are aligned and supplied to an apparatus of the next process from an outlet 39 of a track 34.

In the above-described embodiment, an air nozzle is used as a means for selecting an entangled coil spring conveyed on a truck. However, the difference in size, weight, and the like between the entangled coil spring and a single coil spring, such as the gate plate method described above, is used. Various methods for selecting these using can be adopted.

[0034]

As described above, the vibrating article supply apparatus of the present invention sorts composite articles entangled or overlapped in the middle of a bowl truck from single articles, and separates the selected composite articles by a separation apparatus. And returned to the bowl truck downstream of the sorting site,
The returned single article does not recombined with the article stored in the bottom of the bowl, and the article can be efficiently aligned and supplied alone. Further, since the second sorting means is provided in the middle of the bowl truck on the downstream side of the portion where the separated single article is returned, the article can be supplied to the next step without mixing the composite article at all. it can.
