Abstract

PURPOSE:To perform the front/rear selection reliably and smoothly by providing multiple lugs hooking small inner-diameter holes but not hooking large inner-diameter holes on a selection section so as to select the front and rear in a parts selector of ring-like parts having different-diameter holes on both sides. CONSTITUTION:A parts selector 31 is constituted of a main body 36 having a reversed L-shaped cross section and a pocket 41, and the main body 36 is provided with a side wall 37 and lugs 38. The width and length of the lug 38, a distance 39 between the lugs 38, and a distance 40 from the side wall 37 are set so that parts 1 with their small inner diamter holes facing downward can be hooked but those with their large inner-diameter holes facing downward can not be hooked. The parts 1 reaching the selector 31 are removed from both corner sections of the lugs 38 when their large diameters face downward and are dropped through a gap 40 and are separated to a passage 43. Accordingly, the front/rear selection of the ring-like parts having different inner diameters on both the front and rear faces can be performed reliably.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts sorting device in a vibrating parts feeder.

A helical vibrating chest parts feeder is generally called a parts feeder, and it transfers the parts on the part transfer track by applying screw vibration to a part receiver having a helical parts transfer track formed inside. I have to. A large number of parts are put into the parts receiver and delivered to the outside in a desired attitude. You have to sort out what is not. Type i sorting devices are used depending on the shape and properties of the parts, for example, Fig. 1A,
When it is desired to supply the ring-shaped part (1) as shown in Fig. 1B or the ring-shaped part (5) as shown in Figs. 2A and 2B with the front and back sides aligned, the lamps shown in Figs. 3 and 4A are used. figure,
A parts sorting device aη as shown in FIG. 4B is used.

A truncated cone-shaped hole (4) is formed in the link-like part (1) shown in FIGS. 1A and 18. Therefore, both end faces (
2) The inner diameter is different in (3). Also, Figure 2A,
A hole (8) having a truncated conical shape and a cylindrical shape is formed in the ring-shaped part (5) shown in FIG. 2B. Therefore, the inner diameters of both end surfaces (6) and (7) are different.

In FIG. 3, the entire parts feeder is indicated by (9),
A spiral component transfer track (2) is formed within the ball mill Q as a component receiver. The above-mentioned parts sorting device Qη is provided in a part of this.

This sorting device 0η is formed as an attachment to the ball αO, and has a side wall portion aligned with the side wall portion of the ball QQ and a transfer path forming member that slopes downward toward the outside of the ball Q1 as shown in FIG. 4A. It consists of α. A plurality of arch-shaped protrusions (c) as shown in FIG. 3 are formed on the transfer path forming member Q4.

These projecting pieces (c) extend inward of the ball o0. Moreover, a notch (G) corresponding to the shape of the protruding piece (2) is formed between each protruding piece (C).

When a large amount of the parts (1) shown in Figs. 1A and 1B are put into the pole 00 and torsional vibration is applied, the parts C1l are transferred along the track (B), and the sorting device Oη as described above is transferred.

However, if there is even a slight machining error in the inner diameter of the parts (IJ end faces (2) and (3)) or Loe error in the protrusion (c),
Since the part (1) is transferred with one side toward the side wall (2), even if the part tlJ is transferred with the end face (2) facing downward, the projecting piece (
There are cases where it is not possible to withdraw smoothly from c). Also, even if it passes through as it is, multiple protrusions (c) are formed, so although we are trying to make it detach at any one of the protrusions Q0, it may still pass through and become stuck. . Or a part stopped at one of the protrusions α→ (by υ, the part (
The smooth flow of step 1) may be obstructed.

The present invention has been made in view of the above-mentioned problems, and is shown in FIGS. 1A and 1B.
An object of the present invention is to provide a component sorting device for a vibrating component feeder that can reliably and smoothly sort the front and back of ring-shaped components (υ(5)) as shown in Figures 2A and 2B. According to the present invention, the object is to provide a vibrating parts feeder which transfers the parts on the parts transporting track by imparting vibration to a parts receiver having a parts transporting track formed therein. A part of the parts transfer track is provided with a transfer path that slopes downward toward the side wall, and the transfer path is formed with a protrusion extending toward the side wall, and the inner diameter is Among ring-shaped parts with different diameters, the part with the end face of the larger inner diameter facing upward is passed along the transfer path while contacting the side wall part, and the part with the end face of the smaller inner diameter facing upward is passed through the transfer path as is. Tsu □
This is achieved by a parts sorting device in a vibrating parts feeder, characterized in that the parts are separated from the pieces and are removed downward through a gap between the transfer path and the side wall.

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

In FIGS. 5 and 6, the entire spiral parts feeder of this embodiment is indicated by (1), and the bowl-shaped balls C11l
1, and a drive section (22) is disposed below this.

The entire drive section is covered by a cover.

In the drive unit (2z, the movable core c!61 is a ball (21
1, and is connected to the base group through a plurality of inclined plates. An electromagnet wound with a coil (c) is fixed on the base clJI, and the entire parts feeder is supported on the base by a vibration isolating rubber (c).

When an alternating current is applied to the coil @, a vibration force is generated in the screw 9, and the ball C1l performs an apparent screw vibration.

As shown in FIG. 6, a spiral component transfer track is formed inside the ball circle, and in this upper track portion, from the upstream side, a component single-row single-layer device 1 (7) according to the present invention is installed. A parts sorting device 6υ is provided, and three feed and discharge ends are provided in series.

As clearly shown in FIG. 7, in the component single-row, single-layer device (7), the wiper plates are fixed to the side wall of the ball circle so as to extend diagonally above the track 081, and from the lower end (33a) The distance to the transport surface of the truck is the part (
The thickness of υ is thicker, but it is smaller than twice this. Furthermore, a notch (b) is formed along the track from the track portion facing the fixed side wall portion of the wiper plate (g), thereby making the track blade a narrow path (g).

The parts sorting device 6υ consists of a sorting part body (to) with an inverted-shaped cross section and a pocket (4υ), and the sorting part body (to) is formed as an attachment, and is part of the track (to) of ball C!υ. is inserted into this part and is integrally fixed to the ball Qυ.The pocket (4υ is located outside the main body of the sorting part (to) and is integrally fixed to the ball circle).

Between the main body of the sorting section is an upright side wall section 6 and a ball c!, as shown in FIG. 9A. A plurality of rectangular protrusions are formed at equal intervals in the transfer path section (51) formed from the transfer path section 5D that slopes downwardly toward the outside of D.

The width and length of these protrusions, the gap I3I between each protrusion, and the side wall portion 6 from the protrusion? ) until 1! J(4
The size of part 1 is as follows: The part with the end face (3) facing downward (17 advances the transfer path part 6D as it is, but the part (1) with the end face (2) facing downward has both corners of the protrusion (to) It is selected so that it will detach from the section and fall downward.

The inside (43) of the bokeh (41) communicates with the gap (4), and communicates with the inside of the ball +211 via a passage formed in a part of the pole (211).

The embodiment of the present invention is constructed as described above, and its operation will be explained next.

A large number of parts (1) are thrown into the ball (211), but they are shown scattered in order to make the figure clearer.

When the coil (C) is energized, the ball 12D makes a screw vibration and the component (11) is transported along the track (C).

Up until now, parts have been transported in multiple rows as shown in Figure 7.
! Parts (11) on the inside of D fall at the notch (B). Also, all the parts (1) on the upper layer except for the parts on the lowest layer among the parts [υ] that are transferred in piles fall on the wiper plate (
), and the ball falls into the circle under the guidance of this guiding action. In this way, parts (1) are transported in a single row and in a single layer in the narrow track section (end).

The parts (1) that arrive at the parts sorting device 6υ with the end face (3) facing downward have a much smaller inner diameter on this end face (3) side, so they are simultaneously removed from both corners of the projection (7) as shown in Figure 9A. It does not come off and advances as it is while contacting the side wall portion Cη on the end of the protruding piece.

The part (1) that arrived at the parts sorting device OB with the other end face (2) facing downward has a larger inner diameter on this end face side.
As shown in Figure 9B, from both corners of the projecting piece (to) the end face (2
) side wall part 67) comes off, and the top of the transfer path part (g) is slightly removed.
In Figure 9B, it slides to the right, passes through the gap (40'e) and falls into the inside of the pocket (4υ (43), passage i43
The ball passes through the ball and hits the inside of the ball I211 for 3.

In addition, by forming a plurality of gaps between the protrusions, it is possible to transfer parts ζυ at high speed with high density, and in cases where the parts to be removed together (11) pass through the protrusions on the upstream side. Even if there is, it will be sorted by one of the protrusions on the downstream side.In other words, the reliability of sorting is improved.

As described above, each part (IJ) is supplied from the supply end country to the destination outside with the end face (2) facing upward.

In the above explanation, the part (11) shown in Figs. 1A and 1B has been explained, but the same applies to the part (5) shown in Figs. 2A@ and 2B.

FIG. 10 shows a second embodiment of the present invention, but the other parts of the part 2ida are the same as the first embodiment. The parts sorting device (foundation) of this embodiment also consists of a sorting section body (41) and a pocket (4υ) with an inverted-shaped cross section;
C) consists of an upright side wall portion 1461 and a transfer path portion 6z that slopes downward toward this side wall portion. Different from the example.

The protruding piece uD of this embodiment has an arc shape, and its radius r is smaller than the inner radius on the end face (2) side of the component (1), but the end face (
3) It is larger than the inner radius of the side. Also, the gap between each protrusion curve (
The size of c) is smaller than half the outer diameter of the part (1), but the width of the ring-shaped end surfaces (2) and (3) is larger.
The size of the gap between the protruding piece Uη and the side wall is determined by the size of the gap between the end surface (2
) is large, but smaller than the width of the end face (3).

Among the parts (1) that arrived at the sorting device (44) as described above, the parts (1'' with the end face (3) facing upwards have most of the lower end face (2) removed from the protruding piece 14'0. As a result, the part tilts greatly and falls through the gap into the inner ring of the pocket (4υ).On the other hand, the part with the end face (2) facing upward (
Since the inner diameter of the end face (3) on the lower side of 17 is smaller, the entire part (1r) is stably supported by the protrusion (4?), and the parts (1r as a whole are stably supported by the protrusion (4?), passing over the gap (48) and the protrusion (471) I'll go.

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

For example, in the above embodiments, a spiral vibrating parts feeder, a so-called parts feeder, has been described, but the present invention is not limited to this, and for example, the present invention can also be applied to a so-called linear parts feeder having a linear parts feeder track. Applicable.

Furthermore, in the above embodiments, the shape of the protruding piece ((81t471) is rectangular or arcuate, but the shape is not limited to this, and it is possible to make it take any shape depending on the shape of the inner hole of the ring-shaped part. There are also parts shown in Figure 1A, Figure 1B, and Figure 2A.
The present invention is not limited to the parts shown in FIGS. 2B and 2B.

As described above, according to the component sorting device for the vibrating component feeder of the present invention, ring-shaped components having different inner diameters on both end surfaces can be reliably and smoothly sorted.
