PURPOSE:To feed rod parts having different cross-sections at the opposite ends while arranging by sequentially feeding the rod parts into the grooves under horizontal condition in plural radial grooves made in a rotary disc then contacting one end of the part against the discharging member through rotation of disc and discharging to the outside. CONSTITUTION:Upon bringing some groove 5 in radial direction into the rotary phase to be aligned with the discharge port of a zigazg shoot 11 through rotation of a rotary disc 12, single bolt 1 is fed into the groove 15 to fit the semispherical end 1b of the bolt in a hole 15a at the groove bottom section and lowers without projecting the upper end section from the outercircumferential edge section of the disc 12 nor contacting against the discharge gate 16 when passing through the top section and discharged to the supply shoot 18. When feeding while directing said section 1b toward the outercircumferential section of the disc 12 and arriving to the top section without fitting in the hole 15a, it will contact against the discharge gate 16 and pulled out of the groove 15 to be fallen onto a discharge shoot 17 and to return into the parts feeder 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parts handling device for feeding rod parts, such as stud bolts, whose ends have different cross-sectional shapes, in a predetermined posture.

[Conventional technology and problems]

FIG. 1 shows an example of a stud bolt. In this stud bolt (1), both non-threaded portions (1a) have different cross-sectional shapes.

In some cases, it may be necessary to feed the material to a certain process with the help of its flat end surface. Conventionally, so-called vibrating parts feeders have been used in many cases to sort and feed parts one by one to the next process, and various types of parts are fed to the spiral track depending on the shape and properties of the parts. A sorting means is provided. However, a satisfactory feeding means has not yet been developed for parts with a shape like the one shown in Figure 1 (studpol) (17).As a feeding means, there is a method that takes advantage of the difference in the relative relationship with the center of gravity of the part. However, since the distance from the center of the axial length to the center of gravity of the stud bolt (υ in FIG. 1) is very small, it is difficult to sort it using the above-mentioned sorting means.

[Object and structure of the invention]

Expansion of the present invention In view of the above-mentioned points, an object of the present invention is to provide a parts sorting device that can reliably feed bar-shaped parts as shown in FIG. According to the invention, this object is achieved by providing a rotating disk having a plurality of grooves extending radially to the outer circumferential edge and having a hole formed at the bottom of each of these grooves; and a removal member extending obliquely to the outer peripheral edge of the rotating disk, and the rod-shaped parts having opposite ends having different cross-sectional shapes are sequentially inserted into most of the plurality of grooves of the rotating disk. The part is supplied to a groove in a horizontal state and raised to the top as the rotating disk rotates, and one end of the smaller cross-sectional shape is engaged with the hole of the groove. passing through and descending with the rotation of the rotating disk so that it is guided from the groove to the supply chute by gravity, with the other end of the larger cross-sectional shape facing the hole,
This is achieved by a parts sorting device characterized in that the one end protrudes from the outer peripheral edge of the rotating disk, and then the parts are removed to the outside by contact with the removing member.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 2 to 9.

FIGS. 2 and 3 are a side view and a plan view of a vibrating parts feeder equipped with a parts sorting device according to an embodiment of the present invention. There is a hopper (3) in the center of (6).
(In other words, the stud bolt (1) shown in Fig. 1 is applied to this embodiment.The parts feeding device as a whole is shown as (5), and the parts feeder (4) to stud bolt (1)
is supplied one by one in the manner described below.

In the parts feeder (4), the balls (6) are given a screw vibration force in a known manner by a vibration drive unit built into the casing (7). The entire parts feeder (4) is supported on a foundation made of anti-vibration rubber (8). ball(
A track (9) is formed in a spiral shape on the inner circumferential wall of 6), and a stud pole is formed along this track (9).
(The IJ is transferred under the vibration force of the screw. Note that the track (9) is slightly inclined downward in the radial direction of the ball (6), so it is a stud pole.) (The IJ is biased toward the side wall. Moreover, most of the stud bolts are transported in a stable posture, with their longitudinal direction being turned back and forth. (1) may be caused to fall to the lower track (9) part by the action of gravity.

Discharge end 0Q of track (9) of parts feeder (4)
A zigzag chute Op is connected to. This zigzag chute σ]] is the ball (
6), but in this embodiment it is assumed that it is supported on the foundation by a support even though it is not shown in the drawings.

(zigzag shoe) (as shown in Fig. 4, a staircase (lla) is formed on lυ, and a stud pole (IJ Transferred and fell to the parts sorting device (5).

Also, the stud bolts (slightly larger than the length of υ, stud bolts) 111 of the stairway (Ila) of the zigzag chute συ are regulated to roll with their longitudinal directions turned laterally.

The parts sorting device (5) mainly consists of a rotating disk (6), an auxiliary disk (2), and an exclusion gate (A). ) is rotatably supported on the foundation by a support member (not shown). In addition, in order to stably accommodate the stud bolt (1), the rotating disk @ may be arranged slightly tilted clockwise in FIG. 4. In this embodiment, the auxiliary disk (to) has the same diameter as the rotating disk (2), but the diameter may be slightly smaller than that shown in the drawing.

A plurality of grooves (119) are formed in the rotating disk (2) at equal angular intervals in the radial direction, and these extend to the outer peripheral edge 9, and the bottom of each groove (to) has grooves (119) formed in the radial direction at equal angular intervals. As clearly shown in Fig. 9, a cylindrical hole (15a) is formed.The rotating disk @ is driven to rotate clockwise in Fig. 2, and the groove (15a) of the rotation phase is in a horizontal state. Stud pole) (11) is supplied from the zigzag sheet aη to the groove (g) in the ascending stroke as shown in Fig. @
This is arranged so that it is aligned with the groove (to) of the rotational phase in the horizontal state, which is in the ascending stroke, but after feeding the stud bolt (11e II (g)), the next groove(
(The next stud bolt (1) is in contact with the rotating disc @ until IJ is supplied. This does not prevent the rotation of the rotating disc (6) in any way, but this The stud bolt (1) can be pooled into a zigzag chute circulation. Therefore,
Stud bolts (υ
is supplied.

The removal gate (A) is close to the top of the rotating disk (B) and extends obliquely to the outer peripheral edge of the rotating disk (B). In this embodiment, there is a pair of chutes for removing parts. It is formed as follows. The component removal chute α force is supported on the foundation by a supporting member (not shown), and the ejecting tip is inserted into the opening (6) formed in the side wall of the ball (6) as shown in FIG.
6a). Note that due to the dimensional relationship between the parts sorting device (5) and the parts feeder (4), the discharge end of the chute a7) was set below the upper edge of the ball (6); It is also good to have it facing directly above 6).

As the rotating disk (2) rotates, it starts an upward stroke from the rotational phase aligned with the discharge port of the groove (g) (zigzag shoe) (lη), passes the top, and takes a downward stroke, but this downward movement If the stud bolt (1) is accommodated in the groove 06 during the stroke, the stud bolt (1) is
As shown in FIGS. 2, 3, and 9, the supply chute (to) is arranged to be inclined in accordance with the rotational phase immediately before the material 1 slides down from the groove QI. This supply chute (g)
is supported on the foundation by a support post α9, the lower end of which is connected to the next step (not shown).

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

The rotating disk (6) is rotating at a predetermined speed in the direction indicated by the arrow in each figure, but when a certain groove (G) reaches a rotational phase in which it is aligned with the zigzag chute (1η discharge port), one stud pole ), (II) are supplied to this groove (G) and are stably accommodated as shown in FIGS. 5 and 6.

In this case, the stud pole is supplied with the hemispherical end (1b) facing the bottom of the groove (G) (IJ is the rotating disk (2)
As it rotates, its hemispherical end (lb) engages or fits into the hole (15a) as shown in FIG. 7, and when the groove (2) reaches the top of the rotating disk (2), (The upper end of the IJ is on the same level as the outer peripheral edge of the rotating disk (2), or is below this. Therefore, when passing the top, the stud bolt (1)
) directly enters the downward stroke without contacting the exclusion gate (a), and is discharged onto the supply sheet (to) in the attitude shown in FIG. The stud bolt (υ) is regulated by both side walls of the chute, slides down the seat in its i-position, and is supplied to the next process.

On the other hand, the valve guide (1) is fed into the groove (G) from the zigzag shoe (1υ) with the hemispherical end (lb) facing the outer periphery of the rotating disk as shown in Figure 8. The lower end reaches the top without fitting into the hole (15a) of the groove (G). Therefore, as shown in Figure 5, the protruding hemispherical end (1h) comes into contact with the exclusion gate (g). As the rotating disk rotates, the stud bolt (1) receives a pushing force from the exclusion gate (T) at its hemispherical end (lb), is pulled out from the groove (T), and falls onto the exclusion sheet αη. This stud pole) (IIH) is returned to the parts feeder (4) again.

Since the embodiment of the present invention has the above-described structure and function, the stud bolt (1) shown in FIG. 1 is reliably fed in the direction shown by the arrow.

Although the embodiments of the present invention have been described above, the present invention is, of course, not limited to these and can be modified in various ways based on the technical idea of the present invention.

For example, in the above embodiment, the stud bolts (υ) were supplied to the parts sorting device (5) by the parts feeder, but the stud bolts (υ) are not limited to the parts feeder, and may be supplied by other supply means.

In addition, in the above embodiment, the stud bolt (1) in the opposite direction is removed by the exclusion gate (2) using the exclusion shoe (Q7), but the width of the exclusion chute αη is further reduced.
If the inclination angle of the elimination game) aet is selected appropriately, it is also possible to use this different direction stud pole) (17) as the desired direction.

Further, the present invention is not limited to the stud bolt (1) shown in FIG. 1, but can be applied to any bar-shaped part having different cross-sectional shapes at both ends.

For example, the present invention can be applied to parts such as a stud bolt (1) whose cross section is not circular but polygonal.

Furthermore, it is also applicable to parts in which one end is machined into a conical shape instead of a hemispherical shape as in this embodiment.

The present invention is also applicable to a stud bolt (9) as shown in FIG. That is, this stud bolt (2) also has threads formed on both sides of the non-threaded portion (100a), but one end portion (100b) has a reduced diameter.

Such stud bolts U (to) can be supplied in the direction shown by the arrow.

In addition, in the above embodiment, the hole (
Although the shape of 15a) is assumed to be cylindrical, the shape is not limited to this, and the shape may correspond to the shape of the end of the component as long as it can be easily engaged or fitted.

Further, in the above embodiments, the rotating disk (b) (4) and the auxiliary disk (2) were formed separately, but they may be formed integrally. Furthermore, depending on the case, the auxiliary disk side may be omitted and some means may be provided to prevent the components accommodated in the grooves from falling off during the journey to the top of the rotating disk.

[Purpose of the invention]

As described above, according to the component sorting device of the present invention, rod-shaped components having different cross-sectional shapes at both ends can be reliably sorted in a desired posture.
