Description

Description: TECHNICAL FIELD The present invention relates to a component receiver of a vibrating component feeder, which feeds a plate-shaped component in a standing posture by torsional vibration.

Various types of structures are known as this type of component receiver. Fig. 1 shows an example of this.
A cut groove (2) as a part transfer path (also referred to as a track) is formed in a spiral shape on the inner peripheral wall surface of (1) (also referred to as a ball) in a generally inverted conical shape. (3) represents the inner peripheral wall surface before forming the cut groove (2). The center bottom portion (4) of such a ball (1) has a middle height as shown, and a through hole (5) for fixing to a torsional vibration drive unit (not shown) with a bolt is formed in the center portion. ing.

FIG. 3 is a perspective view of the ball (1) in FIG. 1, but the bolt (12) is inserted into the through hole (5) and screwed into the screw hole of the movable core of the torsional vibration drive unit. By ball (1)
Is fixed to the torsional vibration drive. A ball like this
When a large number of disc-shaped parts m (for example, ceramic capacitors) are put on the central bottom part (4) of (1) and a torsional vibration drive unit (not shown) is actuated, the ball (1) vibrates torsionally. Receives a transfer force in the circumferential direction. However, the central bottom
Around the periphery of (4), a notch as a track on the central bottom (4)
In the recess (6) between the lowermost part of (2), the component m has a strong tendency to overlap in a scaly shape as shown in FIG. 3, and this tendency is particularly noticeable in thin plate-shaped components such as ceramic capacitors. Strongly, even in this state, even if it reaches the entrance of the lower end of the cut groove (2) as a spiral-shaped component transfer path, it is difficult to introduce it into the cut groove (2) individually or as a whole, However, the whole is often continuous and falls downward. In FIG. 3, it may be transferred in a standing posture by the side wall as shown by a part m'in the upper part of the cut groove (2), but due to the above-mentioned reason, there are some blank spaces. Occurs. That is, uneven transportation occurs. This is the discharge end
The supply capability of the component m supplied from (13) is reduced.

FIG. 2 shows another conventional example, but on the inner peripheral wall surface of the ball (7), a spiral track is gradually formed along the inner peripheral wall surface.
(8) is formed. The central bottom member (9) has a bolt insertion hole (1
It is integrated with the ball (7) by inserting a bolt into (0) and screwing it into a torsional vibration driving unit (not shown), but in this example as well, the lowermost part of the track (8) and the central bottom member ( In the peripheral concave part (11) between the part and the part (9), the parts m have a strong tendency to overlap in a scaly shape, and the same problem as the ball (1) in FIG. 1 occurs. Further, the same problem occurs in the rectangular plate-shaped part a as shown in FIG.

The present invention has been made in view of the above-mentioned problems, and is substantially perpendicular to the inner peripheral wall surface of the bowl-shaped container that receives a large number of plate-shaped parts and that has a substantially inverted conical shape. To form a spiral track consisting of a bottom wall having a width sufficiently smaller than half of the width of the component to be transferred and a side wall having a width substantially vertical and larger than the width of the component, and the bottom wall of the track is formed. In a component receiver of an oscillating component feeder in which a plate-shaped component is transferred in an upright position, a cut groove having a V-shaped cross section is formed on a bottom portion of the bowl-shaped container, and both side walls thereof are horizontal surfaces. To form a spiral so as to form the same angle in the opposite direction, one of the side wall portions on the inner diameter side of the bowl-shaped container is connected to the lower end of the bottom wall surface, and the diameter of the bowl-shaped container The other outer side is connected to the side wall portion of the track, and one of the cut grooves is The part that has tilted and abutted against the side wall portion of the bottom wall surface and has reached the lower end of the bottom wall surface falls downward because the center of gravity of the part is inside the edge portion of the bottom wall surface, and falls on the other side wall portion of the cut groove. A component receiver for a vibrating component feeder, characterized in that a component which is tilted and abutted to reach the side wall of the truck is transferred in a standing posture while being tilted and abutted to the side wall of the truck. Achieved by.

An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 5, the vibrating component feeder of this embodiment is shown as a whole.
A central portion (28) 'shown by (14) and having a middle height at the bottom portion (28) of the ball (15) is screwed and fixed to the movable core (17) of the torsional vibration drive unit by a bolt (16). The movable core (17) is composed of a plurality of leaf springs (21) that are inclined at equal angular intervals.
An electromagnet (20) around which a coil (19) is wound is fixed on the base (18) by being connected to the (18). The torsional vibration drive unit is composed of an electromagnet (20), a leaf spring (21), a movable core (17), etc., and the whole is covered by a cover (22). The entire vibrating component feeder (14) is supported on the foundation by a vibration-proof rubber (23).

A cut groove (24) is formed in a spiral shape on the circumferential wall surface (27) of the ball (15) having a substantially inverted conical shape as a part transfer track along the wall surface (27). The track (24) is formed so that the width of the transfer path gradually becomes smaller as it goes upward as clearly shown in FIG. That is, in FIG. 9, the transfer path width of the upper portion (24a) of the truck (24) is t.
If so, the transfer path width of the lower portion (24b) that is one turn downward is formed to be (t + α). Although FIG. 9 shows only two tracks, it is assumed that each track is formed so as to increase by α as it goes downward.

According to the present invention, a spiral cut groove (25) having a V-shaped cross section is formed around the central portion (28) 'of the bottom portion (28) of the ball (15) having a middle height. . This is connected to the lower end of the spiral track (24). As shown in FIGS. 7 and 9, the cut groove (25) is a pair of side wall portions.
(25a) (25b), one side wall (25a) is a ball (15)
Parallel to the inner wall surface (27) of the track (24) and the side wall surface (2
7) '(parallel to the inner wall surface (27)). The other side wall portion (25b) is the bottom wall surface (24) '(transfer path surface) of the truck (24).
Is parallel to and is connected to this. The angle between the bottom wall surface (24) 'of the track (24) and the side wall surface (27)' is 90 °.
Therefore, the angle formed by both side wall portions (25a) and (25b) of the cut groove (25) is also 90 °, and each is inclined at 45 ° with respect to the horizontal plane.

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

The same component (round ceramic capacitor) as the component m described in the conventional example is applied. A large number of parts m are thrown into the ball (15). Inner peripheral wall (27) and side wall surface (27) ′
All of the parts m that have dropped onto the track (24) and have not fallen on the track (24) drop toward the bottom (28) of the ball (15). The component m located on the central portion (28) 'of the bottom portion (28) of the ball (15) is subjected to the action of gravity and the centrifugal force due to the torsional vibration on the inclined surface of the convex surface having the middle height, and the bottom portion (2
Notch groove (25) formed around the central part (28) 'in 8)
Be guided inside. In the cut groove (25), as shown in FIGS. 6 to 9, the component m tilts to either one of the side wall portions (25a) and (25b). Moreover, it inclines to either side at a roughly equal rate. In FIG. 9, a component m inclined to one side wall portion (25a) is represented by a component m, and a component inclined to the other side wall portion (25b) is represented as m '. To be done. Since the cut groove (25) is continuously provided at the ascent of the spiral track (24), that is, at the lower end of the track lower part (24b) (see FIG. 7), the parts m and m ′ are smoothly tracked. (twenty four)
Will be introduced to. In the component m'inclined and introduced into the other side wall portion (25b) in the cut groove (25), the transfer path width of the track (24) becomes gradually smaller, and therefore, as shown by an arrow in FIG. The part m introduced by tilting to one side wall portion (25a) while falling on the side of the side wall portion (25a) when traveling along the track (24) is a track as a cut groove in that posture, that is, in a standing posture. Inclining to the side wall surface (27) 'of (24). Note that, among the components m traveling in a standing posture, the component m on the inner side of the ball is gradually reduced in width of the transfer path of the track (24). 27) Slide down onto the truck (24) directly below.
In this case, since the component m does not drop to the lowermost part, the feeding efficiency of the component can be improved. Thus, the component m can be efficiently supplied from the discharge port (26) in a standing posture. In the figure, the parts m in the balls (15) actually exist at a higher density, but they are shown scattered for the sake of clarity.

The center (2) of the bottom (28) of the ball (15) is
8) 'The parts m are smoothly introduced into the track (24) one after another without overlapping in a scale shape. In the past, the parts m which were introduced into the truck (24) in a scaly form were often continuously dropped and dropped downward. Therefore, a large gap was often generated between the parts in the track (24), but according to the present embodiment, a pair of side wall parts (25a) (25a) inclined at the same angle in the opposite direction with respect to the horizontal plane, that is, each 45 degrees. 25b)
Nihwah receives the same gravitational force and is evenly divided and introduced. Therefore, it is possible to avoid that almost all the parts m fall downward as a group by overlapping in a scale shape. The part m which is introduced by incliningly contacting the side wall portion (25a) is a spiral track on the upstream side which is almost continuous.
Since the parts are transferred in a posture of standing on the bottom wall surface (24 ') as the part transfer path of (24), the parts m can be supplied to the outside extremely efficiently without such a large interval.

Although the embodiments of the present invention have been described above, needless to say, 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, although the disk-shaped parts are applied as the parts in the above embodiments, the present invention is also applicable to the rectangular plate-shaped parts as shown in FIG. 4 and the other plate-shaped parts. Applicable.

Further, although the track (24) is formed as a cut groove along the peripheral wall surface of the ball (15) in the above embodiments, it is also possible to form the track (8) formed stepwise as shown in FIG. The present invention is applicable.

Further, in the above embodiment, the width of the transfer path of the track (24) is formed so as to become gradually smaller as it goes upward, but it may be formed uniformly. In this case, (24a) in Fig. 9
As shown by, the width of the transfer path is slightly smaller than the thickness of the component m (t in the embodiment). Further, the present invention may be applied to a truck (8) shown in FIG. 2 in which the transfer path width is gradually increased toward the upper side.

As described above, according to the component receiver of the vibrating component feeder of the present invention, the plate-shaped components overlap in a scaly shape around the central portion of the bottom of the ball, which reduces the efficiency of introduction into the truck. This can be avoided, and the parts can be supplied to the outside more efficiently than before.
