Abstract

PURPOSE:To remove a should-be-removed part without damaging it, by dividing a part of a part conveying track into a narrow path and an inclined path sloping down in the direction of vibrative conveyance of the part and communicating with the lower part of the track. CONSTITUTION:In a vibratory part feeder 2, a part conveying track 6 is vibrated to convey a part (m). A part of the track 6 is divided into a narrow path 6a and an inclined path 7 sloping down in the direction of the vibrative conveyance of the part (m) and communicating with the lower part of the track. The part (m) to be removed downward from the track 6 is guided to the lower part of the track through the inclined path 7. The element is thus protected from the shock of conventional dropping. Therefore, the part feeder 2 can be safely applied to easily breakable or damageable parts. The part (m) guided to the lower part of the track 6 is conveyed again on the track in the same direction.

Description

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

In general, a vibrating parts feeder is also called a parts feeder, and in a spiral parts feeder, a spiral track is formed inside a bowl-shaped container, and the parts on the track are transferred due to the torsional vibration force that the bowl-shaped container receives. However, the structure is normally such that it is subjected to an altering action by some sorting means during this transportation. For example, in order to transfer parts that have been transferred in multiple rows in a single row, a notch is provided in a part of the track to form a narrow path, and only the parts in the rows on the side wall side pass through this narrow path. However, all the parts in the other rows are made to fall into the lower track section at the notch.

Recently, however, small electronic components are increasingly being used in moving component feeders, but some of these components are easily broken or broken. Or there are some that are weak against shock. When such parts are sorted and transported, if they fall onto the lower track, they will be subjected to a considerable impact force, and there is a risk that they will be broken, the applied parts, or the characteristics changed.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a parts sorting device for a vibrating parts feeder that is capable of preventing parts from being bent or broken and preserving their characteristics. shall be. According to the present invention, this purpose is to provide a vibrating parts feeder that transports parts by vibrating a parts transporting track, in which a part of the parts transporting track is formed into a narrow path;
A ramp slopes downward along the direction of transport of parts due to vibrations and branches into a ramp leading to a lower track section, and parts to be removed downward from the parts transport track are passed through the ramp into the ramp. This is achieved by a parts sorting device characterized in that it guides the parts to the lower track section.

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

In this embodiment, the part m shown in FIG. 1 is handled.

This component m is a crystal oscillator and has a length of approximately 5 to 6 mm.
, width is approximately 1.2-1.5 mm, thickness is approximately 0.35-1.5 mm
0.45 mm, but in order to make the diagrams easier to understand, each part is not necessarily shown in the actual size ratio.
has not shown any signs of vomiting. This embodiment is applied to feed such a part m one by one in the direction of arrow A in the attitude shown in FIG. (2) is a so-called spiral parts feeder, and is equipped with a bowl-shaped ball (3) and a drive unit (4) that generates torsional vibrations, and the entire base is made of anti-vibration rubber (5). supported above. Ball (3
) A spiral track (6) is formed inside the ball (3), and the part m introduced into the center bottom of the ball (3) is transferred on this track (6) in the direction indicated by the arrow by receiving torsional vibration force. Ru. In this embodiment, branch paths according to the present invention are formed at three locations on this track (6). In other words, in this part, the track (6) branches into a narrow road (6a) and a ramp (7), as clearly shown in FIG. The width of the narrow path (6a) is equal to the width of the part m, and the ramp (7) is formed so as to be inclined downward in the transport direction of the part m, so that the width of the narrow path (6a) is equal to the width of the part m. They are installed consecutively. Place tracks (6) in 2 or 3 rows. Of the parts m that have reached this point, place the tracks (6) in
(as shown in Figs. 5 to 11, the part (slightly inclined downward toward the side wall) continues on the narrow path (6a), but other outer row parts m is guided along the ramp (7) into the lower part of the track (6). Ramp (7
) is also slightly inclined downward toward the side wall (7a). In recent NC machine tools, such a ramp (7) can be easily cut into the ball (3) together with the track (6).A fifth attachment is provided at the end of the track (6).
A component suspension start portion (8) clearly shown in FIGS. Component sideways part 00 clearly shown in Fig. 9, parts regulating part Qυ clearly shown in Fig. 10
and a component supply section (one is connected and fixed) clearly shown in FIG. 11, and the component m is supplied one by one to the next process in the predetermined attitude shown in FIG. 1 from the component supply section (b), even if not shown.

The component suspension start part (8) is constructed by inserting a thin plate negative Φ extending to the downstream end of the component horizontal part θ0 to form a block (13a) (
13b) with a screw (g), and this feeding block α1
is fixed to the ball (3) with a screw as shown in FIG. As shown in Figs. 5 to 7, the upper end (14a) of the thin plate α (4) is flush with the upper surface of the block (to) at the upstream end of the block 0, but as it moves toward the downstream side. Accordingly, it gradually protrudes from the top of the block.

The component suspension part (9) is made of a thin plate α4J, and in order to maintain the curved state, a part of the component suspension part (9) has a protrusion (G) formed as a side wall part of the ball (3) and a curved block (171).
It is held between. The component sideways part OO consists of blocks (188x18b) holding the thin plate H, and as shown in FIG.
At the upstream end of 18c), the inclined part (14b) of thin plate α4
is protruding, but from now on, the upper end of the thin plate α is the upper surface (18
c) below or at the same level as the top surface (18c). As shown in Fig. 10, the parts regulating part Qυ consists of a block 4 and a push plate (E), and a notch (19a) formed in the block α is configured so that the part m is regulated and advances upward. has been done. The component supply section (6) consists of a groove forming plate Cυ and a push plate (22), and the groove forming plate (211) is provided with grooves (21a) whose width and depth are slightly larger than the width and thickness of the component m, respectively. , and is formed horizontally, and is covered with a push plate (made in two parts, leaving a slight gap).

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

When using this parts tweeter' (2), first a large number of parts m are thrown into the ball (3), but in order to make the diagram easier to understand, the parts m are shown in a scattered manner.

Parts m move up on the track (6) under the torsional vibration force, but when they reach branching paths (6a) and (7) in the second or third row, the parts m in the row that is in contact with the side wall part Ma\Narrow Road (
6a) The parts m' in the other outer row are the fourth
As shown in the figure, it descends down the ramp (7) toward its side wall (7a) and is led to a track (6) 8 minutes below. In this way, the parts m that have been transferred in multiple rows are sorted into a single row, but the parts m' to be removed are not dropped by movement onto the lower track part as in the past, but are Since it slides quietly down the path (7) due to the transfer action of gravity and vibration, one part m is protected from damage caused by impact. Particularly, the component m is a crystal resonator whose characteristics tend to change due to impact and is easily damaged, so this embodiment is most suitable for such a component m. The part m guided to the lower part of the track (6) is again transported on the track (6) in the same direction. Note that the three branching paths (6a) and (7) are provided when the part m is placed in the middle of the truck (6), and after passing through the branching paths (6a) and (7), it is placed in two rows or again. This is because there may be three rows, but the parts m are reliably guided to a single row (the part m is guided to the part suspension start part (8)).

At the component suspension starting point (8), the upper surface of the block 04 is slightly inclined downward toward the side wall as shown in FIG. 5, so the block 04 advances toward the side wall as shown in FIG.
A thin plate α→ is located between the legs (1a) and (1b) of. Therefore, both the part m with the five legs (la) (lb) - facing forward, and the part m with the legs (1a) (1b) facing backward, the gap between the legs (la) (lb) as it progresses. The upper end (14a) of the thin plate H is held between the two parts, and as shown in Figs. 6 and 7, it gradually rises as it progresses, and when it reaches the parts suspension part (9), it is shown in Fig. 8. As shown, part m is in a suspended state. In this suspended state, it moves over the upper end of the thin plate α (under the transport force caused by vibration), and the 'N3 product sideways part Qq
As shown in FIG. 13, the leg (1a%lb) comes into contact with the end of the block (18b), and the part m receives rotational force in the direction shown by the arrow and falls sideways onto the transfer path (18c). While lying down, move toward the side wall. Note that when it is laid down, it assumes the position shown in Fig. 1. Part m is the parts regulation department. After passing through υ, the parts are supplied from the parts supply section (6) to the next process in a predetermined posture.

In addition, although the overlapping of parts m was not explained in the above embodiment, if the distribution density of parts m is not so high, even if they overlap and reach the parts hanging start part (8) in a row, the parts will be addressed to one piece. There is no problem since it will be suspended by the suspension part (9).

However, in some cases, or depending on the shape of the parts to be applied, a wiper plate may be provided at the entrance side of the branching path (6a) (7) as shown in FIGS. 14 and 15.
The overlapping parts may be guided towards the ramp (7), i.e. the wiper plate (7) has a bent shape;
Its one end is fixed to the side wall of the ball (3), and the distance between its lower edge (30a) and the surface of the trunk (6) is as wide as the height of the part, but less than twice the height of the part. . The tip of the wiper root is directed toward the end of the ramp (7).

Therefore, the overlapping parts are applied 24 forces to the ramp (7) while abutting against the wiper plate (30). In other words, in this case, the narrow path (6a), ramp (7), and wiper plate (row) constitute a component single-layer/single-row sorting section.

The exemplary embodiments of the present invention have been described above, but the present invention is of course not limited to these examples, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiments, spiral type Although a parts tweeter has been described, the present invention can also be applied to a recently developed linear parts feeder.Also, in the above embodiment, three branch paths were provided, but depending on the case, one branch path may be provided. The angle of inclination of the path (7) is not limited to that shown in the figure, but may be made larger or smaller.

Furthermore, in the above-mentioned embodiment, the width w5 (6a) is the width that allows the parts m to pass through in one row, but it may also be the width that allows the parts m to pass through two or three rows.

As described above, in the parts sorting device in the vibrating parts feeder of the present invention, a part of the track is sloped downward along the narrow path and the direction in which the parts are transferred due to vibration, and the lower part of the track is The parts to be removed are guided from the trunk to the lower track part through the ramp and into the lower track part, so that the parts are not dropped in the same manner as in the conventional case. It protects against mechanical shock and can be safely applied to fragile or easily damaged parts.
