Description

[Detailed description of the invention] The present invention relates to a vibrating component feeder.

A vibrating parts feeder is generally also called a parts feeder, and it transfers parts on the track by torsionally vibrating a bowl-shaped container (ball) with a spiral parts transfer track formed on the inside surface.
Each piece is supplied to the next process. When supplying parts of the same type or different types to multiple processes, multiple parts feeders are required. In such a case, the installation area of all parts feeders increases accordingly, causing various inconveniences in factories with limited site areas.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vibrating component feeder that does not increase the site area even when a plurality of vibrating parts feeders are required.
According to the first aspect of the present invention, a plurality of bowl-shaped containers, each having a spiral component transfer track formed on its inner surface, are arranged concentrically with each other spaced apart in the vertical direction along the central axis. and fixed to each other so as to vibrate integrally, and supporting the lowest one of the plurality of bowl-shaped containers on a base via an elastic member so as to be able to torsionally vibrate; In a vibrating parts feeder in which each of the front bowl-shaped containers is integrally torsionally vibrated around the central axis by a common torsional vibration drive unit, as the outer diameter of the plurality of bowl-shaped containers is directed toward the lower stage. The mounting portion is enlarged and has at least one bolt insertion hole formed in the bottom of each bowl-shaped container, and a screw hole aligned with the insertion hole formed in the central bottom of the lower bowl-shaped container of each bowl-shaped container. A vibrating parts feeder, characterized in that the bowl-shaped containers are fixed to each other by inserting a bolt into the insertion hole, screwing it into the screw hole, and tightening it. will be achieved.

According to the second aspect of the present invention, the above object is achieved by:
A spiral component transfer track is formed on the inner surface of each of the outer peripheries of an upright cylindrical body that is supported torsionally vibrate on a base and torsionally vibrates around its central axis by a torsional vibration drive unit, and A plurality of bowl-shaped containers, each having a cylindrical portion having the same inner diameter and a vertical slit in at least part of the center portion and a pair of ears on both sides of the slit, are fitted together so as to be vertically connected to each other. This is achieved by a vibrating parts feeder, characterized in that the parts are slidably disposed at intervals and then fitted and fixed to the upright cylindrical body by tightening the ears of the cylindrical part with bolts. .

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention. In the figures, the parts feeder is indicated as a whole by 1, and includes an upper corrugated cardboard 2, a middle corrugated cardboard 3, and a lower corrugated cardboard 4, which are arranged along the central axis. They are arranged concentrically at intervals in the vertical direction. A common torsional vibration drive unit 5 is provided below. This has a known structure, in which an armature 6 is coupled to a base 7 by a plurality of inclined plate springs 8, and an electromagnet 9 having a coil 10 wound thereon is fixed on the base 7. The entire drive section 5 is covered with a cover 11, and the entire parts feeder 1 is supported on a base by a vibration isolating rubber 12.

A drive unit mounting frame 13 is integrally fixed to the bottom of the lower cardboard 4, and is fixed to the armature 6 of the drive unit 5 with bolts 14. A spiral component transfer track 15 is formed on the inner surface of the lower corrugated board 4, and a supply track 20 is integrally connected to the downstream end of the track 15. Further, a cylindrical frame 16 for attaching the middle corrugated board is fixed to the center of the lower corrugated board 4, and a mounting ring 16a having a plurality of screw holes is integrally fixed to this frame. A spacer ring 17 is arranged to overlap this attachment ring 16a. Spacer ring 17
The mounting ring 16a also has a plurality of screw holes.
are arranged so as to be aligned with each screw hole.

A mounting ring 18 for attaching the lower corrugated board 4 is fixed to the bottom of the middle corrugated board 3, and has a plurality of stepped holes. The middle corrugated cardboard 3 and the lower corrugated cardboard 4 are integrated by inserting bolts 19 into these stepped holes and screwing them into the screw holes of the spacer ring 17 and the mounting ring 16a. Incidentally, a plurality of holes are formed in the bottom of the middle corrugated board 3 to allow the bolts 19 to pass therethrough, but after the bolts 19 are inserted, the holes may be closed with a member such as a rubber cap (not shown). This prevents the inconvenience that the movement of the parts is obstructed by the holes when small parts are supplied.

A spiral track 21 is also formed on the inner surface of the middle corrugated board 3, and a supply track 30 is connected to the downstream end of the spiral track 21. Further, a mounting cylindrical part 22 for mounting the upper corrugated board 2 is integrally formed on the bottom part, and a plurality of positioning pins 26 are implanted in a disc 23 fixed to the upper end part and a spacer 24 superimposed on the disc 23. It is set up. Further, a screw hole block 25 is integrally fixed to the center of the disk 23, and aligned with this, the disk 23 and the spacer 2
A screw hole is also formed in 4.

A mounting block 28 for attaching the middle corrugated board 3 is integrally fixed to the center of the bottom of the upper corrugated board 2, and a bolt 29 is inserted through this central hole to connect the spacer 24, the disc 23, and the screw hole of the screw hole block 25. By screwing them together, the upper corrugated cardboard 2 and the middle corrugated cardboard 3 are integrated. Further, a positioning ring 27 is fixed to the bottom of the upper cardboard 2,
By engaging the positioning pin 26 on the middle corrugated board 3 side with the hole formed in this, the upper corrugated board 2 is positioned with respect to the middle corrugated board 3 in the same direction. A spiral track 31 is also formed on the inner surface of the upper corrugated board 2, and a supply track 32 is connected to the downstream end of the spiral track 31.

As above, upper cardboard 2, middle cardboard 3
and the lower corrugated balls 4 are integrated, but when alternating current is applied to the coil 10 of the electromagnet 9 of the torsional vibration drive unit 5, a torsional vibration force is generated, which causes each ball 2, 3, 4 to rotate around the central axis. Performs torsional vibration. It is assumed that parts are supplied to each of the balls 2, 3, and 4 from each hopper via an appropriate chute even though it is not shown in the drawings. Inside each ball 2, 3, 4, the parts move up along tracks 15, 21, 31, and one part is supplied to the next process (not shown) from supply tracks 32, 30, 20, respectively. Note that a known component alignment means may be provided in each of the balls 2, 3, and 4 to feed the components one by one in an aligned state. Further, the same type of parts may be supplied to each ball 2, 3, and 4, or different types of parts may be supplied to each ball 2, 3, and 4. When supplying parts of the same type, the parts can be supplied to each ball 2, 3, 4 from one hopper via each chute.

As described above, according to this embodiment, although parts are supplied from three balls 2, 3, and 4, the installation area of the parts feeder 1 is almost the same as that for one ball. be able to. Generally, the height of the parts feeder is not very large, so
Even the configuration of this embodiment is not very large and does not pose a problem in various factories.

Further, in this embodiment, since the three balls 2, 3, and 4 can be vibrated by one torsional vibration drive section 5, the cost of the drive section can be lowered than in the past. Of course, since the three balls 2, 3, and 4 are driven in common, the capacity of the drive section 5 becomes larger than when driving one ball, but the geometric size hardly changes.

In addition, the balls 2, 3, and 4 are arranged concentrically along the central axis and fixed to each other so that they vibrate as one, so the vibration as a whole is stable, and each ball The torsional amplitudes of balls 2, 3, and 4 are the same, making it easy to control each subsequent process connected to each ball 2, 3, and 4.

3 to 5 show a second embodiment of the present invention, in which the entire parts feeder is indicated by 40, and five balls 54, 55, 56, 57, 58
is fitted into the upright cylindrical body 53 and fixed thereto. Each of the balls 54-58 has the same construction and has a spiral track 59 formed on its inner surface. The downstream end of track 59 is connected to a linear feed track 60.

A cylindrical portion 61 is integrally formed in the center of each of the balls 54 to 58, the lower end of which protrudes from the bottom of the balls 54 to 58, and a reinforcing ring 62 is fixed thereto. Each ball 5 in the cylindrical part 61
4 to 58 are fitted into the upright cylindrical body 53. In other words, the upright cylindrical body 53 is inserted into each cylindrical portion 61 . As shown in FIGS. 3 and 5, the cylindrical portion 61 has a slit 61a formed in the vertical direction, and a pair of ears 63a and 63b that protrude outward in the radial direction are formed at the upper end of the slit 61a. ing. By inserting a pair of upper and lower bolts 64a, 64b into the holes of these ear parts 63a, 63b, and screwing and tightening nuts thereon, the cylindrical part 61 is elastically deformed to reduce its diameter.
is fixed to the upright cylindrical body 53.

The upright cylindrical body 53 is hollow, and a lid 65 is fixed to the upper end to prevent foreign matter from entering.
A hook 66 is also fixed to this. Using this hook 66, the entire parts feeder 40 can be transported by, for example, a crane.

Below the upright cylindrical body 53 is a torsional vibration drive unit 4.
1 is provided. In this drive unit 41 as well, the armature 42 and the base 43 are coupled by a plurality of inclined plate springs 44, as in the first embodiment.
An electromagnet 45 having a coil 46 wound thereon is fixed on the top of the electromagnet 3 . The entire drive section 41 is covered by a cover 47, and the entire parts feeder 40 is supported on a foundation by a vibration isolating rubber 48.

A mounting plate 49 is integrally fixed to the upper surface of the armature 42, and is fixed to a mounting plate 50 fixed to the lower end of the upright cylindrical body 53 by bolts 51. A reinforcing disk 52 is further fixed to the lower end of the upright cylindrical body 53. Although not shown, it is assumed that parts are supplied to each of the balls 54 to 58 from each hopper via an appropriate chute. When alternating current is applied to the coil 46 of the electromagnet 45 of the torsional vibration drive unit 41, a torsional vibration force is generated, which causes each ball 54 to 5 to
8 performs torsional vibration around the central axis of the upright cylindrical body 53. Inside each of the balls 54 to 58, the parts move up along a track 59, and one part is supplied from each supply track 60 to the next process (not shown). Note that a known component alignment means may be provided in each of the balls 54 to 58 to feed the components one by one in an aligned state. Also each ball 54
58 may be supplied with the same type of parts, or different types of parts may be supplied. When supplying parts of the same type, the parts can be supplied from one hopper to each ball 54-58 via each chute.

This embodiment also has the same effects as the first embodiment, but also has the following effects.

That is, the height of each of the balls 54 to 58 can be freely selected within the range of the height of the upright cylindrical body 53. Further, in the illustrated embodiment, the position of the supply track 60 in the circumferential direction is
4 to 58, but this position can also be freely selected. That is, bolt 64
After loosening a and 64b, the balls 54 to 58 can be easily set to a desired rotational position by rotating the balls 54 to 58 in the circumferential direction along the outer peripheral surface of the upright cylindrical body 53. This is useful, for example, in adjusting the connection position between each ball and the next process.

Further, each ball 54-58 is connected to a common upright cylinder 5.
3, making centering work easier. In addition, as long as the inner diameter of the cylindrical portion 61 is the same, it is possible to freely replace the ball with another ball, and other various effects are achieved. That is, in the illustrated example, the balls 54 to 58 have exactly the same configuration, but different types of balls may be fitted together.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the torsional vibration driving section is of an electromagnetic type, but instead of this, it may be of a type that uses a pair of vibrating motors as is known in the art.

Further, in the above embodiments, the torsional vibration driving section is disposed below the plurality of balls, but it may be disposed above the balls instead of this.

Further, in the embodiments shown in FIGS. 1 and 2, the diameters of the upper corrugated cardboard 2, middle corrugated cardboard 3, and lower corrugated cardboard 4 are increased in order from the top, but they may have the same diameter. Further, the number of stages is not limited to three, and may be two or four or more stages. The same applies to the embodiments shown in FIGS. 3 to 5, and balls having different diameters may be used.

As described above, according to the vibrating component feeder of the present invention, although it has a plurality of balls, the installation area is almost the same as the conventional case of one ball, and one torsional vibration drive unit Since these are commonly used as the drive section, the cost of the drive section can be reduced. Furthermore, since the torsional amplitude of each ball can be made the same, control of each subsequent process becomes easy. Furthermore, according to the second invention, the ball discharge port can be easily positioned at various heights and angles by tightening and loosening the bolts at the ears of the cylindrical portion, thereby increasing the degree of freedom in connection to each subsequent process. You can take it. Further, according to the first invention, it is possible to reduce the number of parts and increase the number of stages of balls,
Also, installation work to each lower stage is easy.
