〔Example〕

Hereinafter, a vibrating component feeding apparatus according to an embodiment of the present invention will be described with reference to the drawings.

1 and 2, the vibrating parts feeder is indicated by (1) as a whole, and a spiral track (3) is spirally formed in the ball (2). As clearly shown in FIG. 1, a movable core (4) is integrally fixed to the bottom portion of the ball (2), and a base ( 6) combined with. An electromagnet (8) around which a coil (7) is wound is fixed on the base (6) and faces the movable core (4) described above with a gap. The torsional vibration drive unit is configured as described above, and the whole is covered with the tubular cover (9). The entire vibration parts feeder (1) is supported on the floor by the vibration proof rubber (10).

As shown in FIG. 2, the track (3) is provided with a sloping surface (12) inclined downward in the radial direction and has a side wall (also shown in FIG. 1). 11) is provided, and the bend detecting section (14) according to the present invention is provided so as to be connected to the downstream side thereof. In the embodiments of the present specification, the truck (3) and the contact truck (11) are collectively defined as a spiral track in the claims. As shown in FIGS. 2 and 4, the connecting track (11) has its downstream end aligned with the extending direction of the bend detecting section (14). The legitimate parts that have passed through this position are supplied to the next process through the posture holding track (15).

The details of the bend detecting portion (14) are shown in FIGS. 3 and 5, but the bend detecting portion (14) is mainly located on the component receiving portion (13) integrally formed with the ball (2) and the upper portion thereof. It consists of a bend detection track (16) fixed to the ball (2), and the bend detection track (16) consists of a straight plate, which is fixed laterally from the ball (2). Mounting member (17) and bend detection track (16)
The bending detection track (16) is integrally fixed to the ball (2) by integrally mounting the attachment member (18) fixed to the ball (2) with the screw (19). As shown in FIG. 5, a V-shaped groove (16a) is formed at the upper end of the bend detection track (16). The width of this groove 16a is from the fourth
As clearly shown in FIG. 9 (particularly FIG. 5), the lead wires l ₁ and l _{2 that} are smaller than the diameter of the main body P of the component m and extend from the center of both ends of the main body P have an allowable bending size. The size is determined accordingly. Although not clearly shown in FIGS. 1 and 2, the components m are supplied to the connecting track (11) in a single line. For this reason, the ball (2) has a means for arranging in a single row, for example, a notch is provided in the track (3) to form a narrow path so that the parts that have reached multiple rows in this way are guided to the downstream side in a single row. It is assumed that

The embodiment of the present invention is configured as described above. Next, this operation will be described.

It is assumed that a large number of parts m are put in the ball (2). When alternating current is applied to the coil (7), an alternating attractive force is generated between the movable core (4) and the electromagnet (8), which causes the ball (2) to perform a known return vibration. As a result, the component m is transferred by vibration along the track (3), and when it reaches the connecting track (11), it is transferred to the downstream side while sliding down the inclined surface (12). At this time, it is transferred along the side wall portion constituting the connecting track (11) and is surely guided to the bend detecting portion (14). In the bend detecting section (14), the bend detecting track (16) extends linearly, and the component m has its axial direction in the transfer direction in the groove (16a) formed at the upper end of the bend detecting track (16). Will be introduced. That is, the fourth
As clearly shown in the figure, the discharge end of the communication track (11) is aligned with the groove (16a), so that the component m can be introduced with the axial direction of the transfer direction. A lead wire like the part m'shown on the leftmost side in FIG.
If l ₁ and l ₂ are straight, they are transferred through the groove (16a) by vibration as they are, then they are guided to the posture holding track (15) through this groove, and their axial direction is directed in the transfer direction. And is stably supplied to the next process.

However, the parts in which the lead wires l ₁ and l ₂ are bent in a certain amount or more in a certain direction, as shown in FIG.
Since the center of gravity of the entire component is located outside the both edges of the groove (16a), the component falls into the pocket (13). still,
Even if the center of gravity of the whole is located slightly inward from both edges of the groove (16a), it is transferred by vibration, but especially because it is subjected to torsional vibration, centrifugal force acts radially outward. Parts with bent lead wires more than a certain amount will surely fall into the pocket (13). Note that the lead wire l ₁ ,
The part where l ₂ is not bent passes through this part and is led to the next process as a good product.

FIG. 6 and FIG. 7 show the bending detecting section in the vibrating parts feeder according to the second embodiment of the present invention. In this embodiment, the contact plate (30) is located at the center of the bending detecting track (16). It is fixed to one side of the section as shown in FIG. Taper (30a) on the part introduction side of this contact plate (30)
Are formed. Even in such a bend detecting portion, similarly to the first embodiment, the component in which the lead wire is bent by a predetermined amount or more falls into the pocket (13), but in this embodiment, the taper portion (30a) is formed. By providing the contact plate (30), as shown in FIG. 6, when the lead wire l ₂ is bent by a predetermined amount or more, it comes into contact with the taper (30a) so that the pocket (13) can surely and quickly. Can be dropped into. Since it is transferred by vibration, it does not always approach the contact (30) in the posture shown in FIG. 6,
Even if the part m passes through the taper (30a), the center of gravity of the part m is deviated from the axis of the part m due to the bending of the lead wire. As is apparent from FIG. 7, the lead wire l ₂ bent to change is abutted against the contact plate (30) to receive a shock from the contact plate (30) and is removed to the left in FIG. It At this time, the length of the contact plate (30) is longer than the total length of the component m. Incidentally, as shown on the right side of FIG. 6, the component m'in which the lead wires l ₁ and l ₂ are straight passes through as it is.

FIG. 8 and FIG. 9 show a third embodiment of the present invention, but in this embodiment the contact plates are further provided on the upstream side and the downstream side. A taper (40a) is provided on the component introduction side of the upstream side contact plate (40).
It is similar to the embodiment. The second contact plate (41) is also provided on the downstream side.
Is provided, and a taper (41a) is also provided on the component introduction side, but this contact plate (41) is a side surface opposite to the side surface of the track (16) to which the contact plate (40) is fixed. Therefore, as shown in FIG. 8, the component m, which has the lead wire l ₂ bent to one side forward, passes through the side of the contact plate (40) while maintaining such a posture. Even if you do, the second
The contact plate (41) can be surely removed into the pocket (13). It is to be noted that the component m constantly changes its posture in the rotational direction about the axial direction in response to the vibration.
Like the first embodiment, the first contact plate (40) eliminates most of the parts whose lead wires are bent by a predetermined amount or more, although the contact plate is shorter than in the first embodiment. It can be more surely eliminated by the second contact plate (41).

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

For example, the length, the number, and the mounting interval of the contact plates are not limited to those shown in the drawings, and can be appropriately selected depending on the size and length of the portion. In the above embodiments, the capacitor was described as a component. The present invention is not limited to the above, and any component including a substantially cylindrical main body and a pair of legs extending in the axial direction from both ends thereof can be applied to the present invention.

〔The invention's effect〕

As described above, according to the component feeding apparatus of the present invention, in a component including a substantially cylindrical main body and legs extending in the axial direction from the centers of both ends of the main body, the pair of legs is provided with a predetermined amount. The bent parts are automatically eliminated, and all non-defective parts can be supplied in the next process. Therefore, it is not necessary to detect the bending of the leg portion in the next step, and the cost of the entire apparatus can be reduced.
