Not not. In particular, for a cylindrical part having a diameter of the bottom surface larger than the height of the side surface, when it is transferred by the torsional vibration part feeder, it takes an upright posture in which the bottom surface is in contact with the transfer surface and a horizontal posture in which the side surface is in contact with the transfer surface. There is a large proportion of people who take a stable upright posture because they are sometimes received. There is a case where it is desired to supply such a cylindrical part to the next process in an unstable horizontal posture, but a feeding device capable of meeting such a request has not yet been developed. However, in order to feed such a columnar component to the next process in a rolling posture, the strip-shaped member is twisted by 90-degree canning processing, and the cylindrical component in a stable posture is transferred along the side surface by torsional vibration. It is conceivable to change the posture to 90 degrees along with this while receiving the force. However, 90 of such strips
Twisting and canning is very difficult and cannot be done precisely, and it is necessary to attach such a member to the torsional vibration part feeder so as to obtain the desired action (whether this is welding or (Due to screw mounting) is very difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. For example, a cylindrical part having a bottom surface diameter larger than a side surface height and a stable upright posture is supplied to the next step in a horizontal upright posture. An object of the present invention is to provide an apparatus for feeding a cylindrical part to be obtained.

[0004]

[Means for Solving the Problems] The above object is to provide a block-like component in a recumbent posture and the same component in a standing posture on a track that vibrates in a torsional manner, though the height is smaller than the height of the component in the standing posture. The height selection part having a gap larger than the height of the parts in the laid posture is provided, the components in the recumbent posture are transported on the radially outer side, and the components in the standing posture are transported on the radially inner side,
Next, the component in the recumbent posture slides on the downward inclined surface, and the component in the standing posture is converted to the recumbent posture when the step is dropped, and these components are passed through the downward inclined surface and the step and are joined by the downstream merging truck. The parts are merged, a groove twisted by 90 degrees is formed along the axial direction on the outer peripheral surface of the substantially cylindrical block provided on the most downstream side, and the part in a recumbent position is introduced into the groove. This is achieved by a vibration adjusting device for parts, which is configured to change its attitude and to be supplied to the next process.

Further, the above object is to connect a track of a torsional vibration parts feeder for transferring a cylindrical part having a diameter of the bottom surface larger than the height of the side surface, and to bring the bottom surface into contact with the transfer surface of the track. A sorting track is provided which has a gap through which the columnar component in the upright position can pass but the side face contacting the transfer surface cannot pass through the columnar component, and the columnar component in the upright position is In the outer portion of the sorting truck, there is provided a sorting / separating portion for separating and transferring the columnar component in the horizontal posture to the inner portion, and a merging truck having a step from the downstream end of the sorting truck to the upright posture. Of the columnar component, the descending slope along the step is slid down in the same posture, and the columnar component in the horizontal posture is caused to fall down the step and converted into the upright posture, thereby the columnar component in the upright posture. It has a merging part to be merged and a rectangular tubular cross-sectional shape that can be transferred in a single row single layer while maintaining the posture of the columnar component in the upright posture that has been selected and separated, and is almost between the upstream end and the downstream end. A 90-degree twisted portion is formed to form a track twisted by 90 degrees, and the columnar component transferred in an upright posture at the upstream end is provided with a block-shaped 90-degree twisted portion that is laterally oriented at the downstream end. This is achieved by a vibration feeding device for parts, characterized in that the cylindrical parts are fed from a discharge end of a vibrating parts feeder in a horizontal position.

Is introduced into a groove formed on the outer peripheral surface of the columnar block provided in, and is transferred by receiving a torsional vibration force along the groove and is changed in 90 degree posture and supplied to the next process in a standing posture. . Since it is possible to easily form a groove twisted 90 degrees in a cylindrical block by cutting with an end mill, for example, the block-shaped part can be set up with high efficiency without significantly increasing the device cost. Can be supplied to the next process. According to the second aspect of the present invention, the cylindrical part having the diameter of the bottom surface larger than the height of the side surface, which is transferred through the track of the torsional vibration part feeder, contacts the bottom surface with the transfer surface by the gap provided in the sorting and separating unit. The columnar parts in the upright position are separated and transferred to the outer part of the sorting truck, and the columnar parts in the upright position that contact the side surface with the transfer surface are transferred to the inner part. In the vertical posture, the columnar component in the upright posture slides down the descending slope along the step while keeping the posture as it is. By joining the parts, the proportion of the upright posture in the cylindrical part is increased. Then, the cylindrical parts in the upright posture are sorted and separated, and the rectangular cylindrical track having a cross-sectional shape in which the posture is maintained and transferred in a single-row single layer and twisted by about 90 degrees between the upstream end and the downstream end. By being transferred,
The cylindrical parts are fed in a horizontal position from the discharge end of the torsional vibration parts feeder.

Referring to FIG. 9, a step 65 is provided at this connection point, and the upstream outer sorting track 53A is transferred. The part F in the upright posture, which has been performed, slides down the slope 66 following the step 65 in the same posture.
The component F in the horizontal posture, which has been transferred from the upstream inner sorting truck 53B, falls on the step 65, assisted by the fact that the posture is inclined by fitting into the U-shaped groove 58 at the downstream end of the truck 53B. When you do, you will be in an upright position. Then, it joins with the component F in the upright posture, which has slid down the slope 66. Therefore, the ratio of the upright posture of the part F on the merging / sorting truck 63 at the merging point is higher than that of the part F in the upstream sorting part 50.

Referring to FIGS. 4 and 9, the joined parts F are joined together.
Among them, only the part F in the upright posture is the protruding portion 6 of the separating member 67.
Although the part F in the horizontal position cannot enter the lower part of the overhanging part 67a, the part F in the horizontal position cannot move under the overhanging part 67a, and the parting / sorting track 63 is transferred in contact with the overhanging part 67a.
Then, the component F when the transfer amount is excessive at the downstream end portion of the merging / sorting truck 63 is removed from the removal notch 69 to the bowl 2

Since it acts, the ratio of the upright posture of the component F merged in the vicinity of the downstream end of the slope 76 is higher than that of the component F in the first merge selection unit 60.

Referring to FIGS. 4 and 11, of the joined parts F, only the part F in the upright posture enters below the overhanging portion 77a of the separating member 77, slides down the slope 74, and then, as shown in FIG. As shown, it is transferred to a horizontal tunnel-shaped introduction path 82 whose width is narrowed by the separation piece 81. On the other hand, the component F in the horizontal posture that cannot enter below the projecting portion 77a of the separating member 77 is transferred to the merging / sorting truck 73 together with the component F in the excessive vertical position, and the transfer amount is excessive with reference to FIG. In this case, it is returned to the bowl 21 through the exclusion notch 79. The component F in the upright posture, which is transported to the downstream end of the merge selection truck 73, is guided to the separation piece 81 and returned to the bowl 21 via the return path 83.

The upright posture part F guided to the tunnel-shaped introduction path 82 is formed by twisting 90 degrees from the upper side to the outer side of the side surface of the cylindrical block 91 in the posture changing portion 90 with reference to FIG. By transferring the posture changing track 93 formed by the rectangular groove and the cover member 95 thereof, the downstream end thereof is in a horizontal posture, and the discharge port 106 provided at the downstream end supplies the same to the next process. To be done.

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

For example, in the present embodiment, in forming the twisted rectangular tunnel-shaped posture changing track 93, the side surface of the cylindrical block 93 of SUS material is cut by an end mill to form the necessary square groove. However, the square groove can be formed by a method other than this.

Further, in this embodiment, as shown in FIG. 17, the sorting section 5 to be replaced according to the size of the component F.
Although 0, the first merging / sorting unit 60, the second merging / sorting unit 70, and the posture changing unit 90 are integrated by argon welding, they may be joined by bolts. In addition, if necessary, a part of these connections, for example, the posture changing unit 90 or the selecting unit 50 may be separately replaced without being integrated.

Further, in this embodiment, the first merging / sorting section 6
0, the unit of the second merging / sorting unit 70 has steps 65, 75
Is used as a boundary, and the first merging / sorting unit 60 is a unit that separates the component F by the overhanging portion 67a of the separating member 67 after merging the components F. For example, these may be connected as a unit in which the parts F are separated and then merged.

Further, in the present embodiment, the cylindrical ferrite molded product has been described as the object to be transferred, but other cylindrical parts such as roller bearing rolling elements, thick washers, and various other parts may be used. It can be transferred.

Further, in the above-mentioned embodiment, the cylindrical part is explained, and this is the part whose diameter is larger than the height. However, it is not limited to such a part, and FIG.
It may be a block-shaped part as shown in FIG. That is, as shown in (A), the cuboid-shaped component M has an unstable standing posture.
Although it is a stable posture, that is, a recumbent posture shown in FIG. 3, such a component M can be converted from the recumbent posture of (B) to the standing posture shown in (A) and supplied to the next process. The present invention is applicable. In short, the present invention can be applied to all block-shaped parts in which the lying posture is a stable posture, the height from the transfer surface is a standing posture, and the height from the transfer surface is larger. In addition,
In the above-mentioned embodiment, it is a cylindrical part, and it is possible to share three kinds of parts (however, some members are replaced), and each of them is 3.4 mmφ × 2.9 mm and 4.5 mmφ × 3.
It is 5 mm, 5.1 mmφ × 4.6 mm, and d is larger than h in any case, but d and h are very close to each other. Therefore, the cross-section formed in the cylindrical block 91 has a constant width for the rectangular cylindrical notch groove and can be twisted 90 degrees without any problem. However, in the case of a block-shaped part as shown in FIG. At the upstream end, the width is considerably larger than the thickness of the component in the recumbent posture, so that the notch groove becomes small depending on the twist angle as it goes from the upstream end to the downstream end. There is a need to. However, also with the end mill, numerical control machining can be easily performed. Of course, in the above embodiment, depending on the difference between d and h, the width or height may be made slightly larger or smaller toward the downstream end.

Further, in the above embodiment, the step slopes having the same structure as the step 65 and the slope 66 are provided at two places, 75 and 76, but they may be further increased. Alternatively, the step 65 and the slope 66 may be provided at one location. It is desirable to determine this in relation to the shape of the part and the position of its center of gravity. In any case, in the present invention, the action of torsional vibration is effectively utilized, and during the transfer on the track due to the torsional vibration,
For example, in the height selection section, a component with a height smaller than the gap is smoothly guided radially outward in the height selection unit because the centrifugal force is always applied outward. Parts having a large height are guided and transferred along the side surface, and further fall in the step 65 and the slope 66 while receiving the centrifugal force when the step 65 is dropped, which is an unstable posture. That is, since the height of the center of gravity is higher than that of the surface of the track, the posture is changed while tilting radially outward and contacting along the side surface of the slope 66 in this embodiment. In a truck, almost all of them can lie in a recumbent position efficiently.

As described above, according to the vibration feeder for parts of the present invention, for example, a circle having a block shape, a bottom surface diameter larger than the side surface height, and an upright posture standing on the bottom surface is stable. The columnar parts can be fed and fed in a single-row single layer as an unstable horizontal posture standing on the side surface, and the productivity of the next process that requires the columnar parts in the horizontal posture is remarkably increased.
