Next, the operation of this configuration will be explained based on FIGS. 1 and 4 to 12. Parts with lead feet (hereinafter referred to as
It's called parts. ) moves toward the top of the bowl 1 along a spiral track provided inside the bowl 1 due to torsional vibrations applied to the bowl 1 by a vibrator (not shown). During this time, most of the parts are regulated by the width of the track, and most of the parts are regulated in the longitudinal direction with respect to the direction of movement as shown in the figure. reach. The adjustment fitting 7
1 and 4, which is a sectional view taken along line A-A' in FIG.
As shown in the figure, an adjustment fitting mounting plate 7 is attached to the notch 2a of the top track 2 through the ball side surface 1a and is attached to the ball 1 at the position shown in the figure so that it can be freely inserted and removed.
b and its own elongated hole 7c with a bolt 7a, so that the width of the track of the notch 2a of the track 2 can be adjusted. Using the adjustment fitting 7, the width of the track at the cutout portion of the track 2 is adjusted so that the number of rows of components becomes the desired number, and misaligned components are caused to fall onto the inner periphery of the track. As a result, downstream of the notch 2a of the track 2, the parts are arranged in the desired number of rows. The part advances further until it reaches the end of the track. The side surface 1a of the bowl at the terminal end is notched, and the conveying section 8 provided continuously with the notch 1b is inclined downwardly outward with respect to the bowl 1, and the parts are conveyed through the notch 1b. After that, the torsional vibration caused by the bowl 1 of the conveyance section 8 causes the conveyance section 8 to advance towards the outlet 8a. A reversing rod 9 is provided at a predetermined location near the notch 1b as an auxiliary means for aligning the components in a desired direction. Figures 5a and 5b show how the parts are aligned by the reversing rod 9, and the positional relationship when viewed in cross section in the vertical direction of the reversing rod 9 is shown in Figure 5.
It is shown in figure c, which is a sectional view taken along line B-B' in the figure. As shown in Fig. 5a, the component whose lead foot b is at the top gets caught on the reversing rod 9, rotates around the reversing rod 9, slides down the downward slope, and then twists. As it vibrates, it advances inside the conveying section 8 with the main body a at the beginning. On the other hand, as shown in FIG. 4b, the component with the lead leg b at the top slides down the downward slope without the main body a getting caught by the reversing rod 9.
Thereafter, it moves through the conveyance section 8 in the same posture as it is subjected to torsional vibration. As a result, many parts can proceed toward the outlet 8a of the conveyance section 8 with the main body a at the head, thereby assisting the alignment action of the ring bowl 4, which will be described later.

The parts then proceed from the outlet 8a to the ring bowl 4 for aligning the parts in the hanging direction. A ring 5 that receives the parts delivered from the delivery port 8a.
is rotatably provided in the ring bowl 4,
The ring bowl 4 rotates in the direction of arrow C shown in FIG. 1 in conjunction with torsional vibration of the ring bowl 4 by a not-shown vibrator. The parts sent out from the delivery port 8a of the transport section 8 are finally suspended in a desired direction by the bowl ring 4. This situation is shown in FIGS. 6 to 12. FIG. 6 shows the structure of the ring bowl 4. As shown in the top view of FIG. 6a, the ring 5
is supported by the ring receiver 5a and rotates. In addition, as shown in the side view of FIG. 6b, the ring 5 of the part
In order to fit into the notch on the outer periphery of the ring and to improve the holding condition of the parts, the upper surface of the ring receiver 5a is inclined downward toward the center, and accordingly, the lower surface of the ring 5 is also inclined toward the center. slopes downward. A ring holder 5a holds the ring 5 in a bowl of a ring bowl 4 (not shown). FIG. 7 shows how parts fit into the ring 5 with this structure. Many of the parts that have been advanced with main body a at the beginning fit into the notches on the outer periphery of ring 5 on ring receiver 5a that is tilted downward toward the center as shown in FIG. move with you. At this time, stable fitting can be achieved by utilizing the inclination, regardless of the material of the lead foot portion of the component or the position of the center of gravity of the component. Other parts fit into the notches during the rotation of the ring 5, or simply ride on the ring 5 and move with the rotation of the ring 5, and are finally returned by the spring plate 6. It is discharged to the receiving plate 3 for use. On the other hand, as shown in FIG. 7b, the parts sent out with the lead leg b at the top do not fit into the ring 5, but simply ride on the ring 5 and move as the ring 5 rotates. , Finally, all the return plates 6 are connected to the return receiving plate 3.
is released. The state at this time is shown in FIG. 9, which is viewed in cross section in the vertical direction. Return receiving plate 3 is bowl 1
The parts ejected to the return receiving plate 3 are returned into the bowl 1 through the notch 1c on the side of the bowl.

In this way, only the parts that fit into the ring 5 in the desired direction move as the ring 5 rotates and reach the notch 5d of the ring receiver 5a shown in FIG. 12. FIG. 12 is a top view of the notch of the ring receiver 5a with the ring 5 of the ring bowl 4 removed. As shown in FIG. 8a, the notch 5
An auxiliary plate 5b for aligning the hanging direction is fixed to the lower surface of d to maintain the hanging direction of the parts.
Further, above the outer edge of the auxiliary plate 5b for aligning the hanging direction, the distance D from the upper end of the L-shaped vertical portion of the auxiliary plate 5b shown in the figure is shorter than the radial length of the main body a of the component. An auxiliary member 5c for aligning the hanging direction (in FIG. 8 and the like, it is a rod-shaped member, but it may also be a plate-shaped member) is provided to prevent parts from falling. Here, FIG. 8 is a vertical cross-sectional view of the notch 5d of the ring receiver 5a. In addition, adjacent to the upstream end of the hanging direction alignment auxiliary member 5c in the rotational direction of the ring 5, there is a component introduction part (not shown) that is inclined downward in the downstream direction of the rotational direction of the ring 5. . The introduction part is an auxiliary means provided to guide the foot of the component held by the ring receiver 5a at the position of the auxiliary member 5c for aligning the hanging direction.

The function of aligning the components in the hanging direction at the notch 5d of the ring receiver 5a will be described for each component characteristic.

First, if the center of gravity is at the lead foot, as shown in FIG. 8, when the part advances to the notch 5d,
It falls to the upper end of the L-shaped vertical portion of the auxiliary plate 5b for aligning the hanging direction, and then rotates using the upper end as a fulcrum, and finally becomes the hanging direction. On this occasion,
The hanging direction alignment auxiliary member 5c prevents the parts from falling due to rotation of the ring 5 or the like. Further, the posture of the component in the hanging direction is maintained at the upper end of the L-shaped vertical portion of the hanging direction alignment auxiliary plate 5b.

Second, for a component that does not have a center of gravity in the lead leg b, which is the subject of this application, the hanging direction cannot be determined by the action of gravity alone, so as shown in FIG. An auxiliary plate 11 that is taller than the vertical part is attached to the L-shaped horizontal part of the auxiliary plate 5b for aligning the hanging direction, and the auxiliary plate 11, the auxiliary plate 5b for aligning the hanging direction, and the auxiliary member 5c for aligning the hanging direction direction. The auxiliary plate 11 is the first
As shown in FIG. 2, the distance between the auxiliary plate 5b and the L-shaped vertical portion becomes gradually narrower toward the parts discharge section. The effect of this configuration will be explained over time. First, it falls onto the auxiliary plate 11 as shown in FIG. Next, as shown in FIG. 11a, the parts slide toward the outer periphery of the auxiliary plate 5b for aligning the hanging direction, and are held by the auxiliary plate 11 and the auxiliary plate 5b for aligning the hanging direction. At this time, the parts are prevented from falling by the hanging direction alignment auxiliary member 5c. Further, as the rotation of the ring 5 progresses toward the discharge direction, the interval between the auxiliary plates 11 provided on the auxiliary plate 5d for aligning the hanging direction becomes gradually narrower.
As shown in FIG. b, the parts gradually approach the hanging direction while being prevented from falling by the hanging direction alignment auxiliary member 5c. Finally, by the time the rotation of the ring 5 reaches the component ejecting means, the component is completely suspended in the direction shown in FIG. This means can be applied to a component whose center of gravity is at the lead foot, and has the effect of increasing the stability of the component in the hanging direction.
When the component reaches the longitudinally concave component delivery aid 12 shown in FIG. 1 as the ring 5 rotates,
The part is held in a suspended state by the metal fitting, and the ring 5
withdraw from the rotational motion of. The parts are sent to the next process through a chute 10 provided in series with the metal fitting 12. The configuration of the chute 10 may be as shown in FIG. 13. As shown in FIG. 13a, the chute 10 has a sliding plate 13 and a side holding plate 14.
It has a structure with a. Particularly for parts that tend to fall over because their center of gravity is on the main body, a magnet 15 is installed at the bottom of the chute 10 as shown in Figure 13b.
It is possible to shoot in a stable suspended state.
Further, as shown in FIG. 13c, a chute may be provided between the sliding plate 13 and the side holding plate 14 with means for discharging parts that have fallen down.

[Effects] As described above, according to the present invention, parts with lead feet, whose center of gravity is on the main body, which was previously difficult to align while suspended, are reliably aligned in a certain direction and the next This has the remarkable effect of being able to be sent to the process.
