Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a parts sorting device in a vibrating parts feeder.

[Conventional technology and its problems]

A vibrating parts feeder is generally called a parts feeder, and in most conventional parts feeders, torsional vibration is applied to a bowl-shaped container (ball) that has a spiral track inside.
The parts on the track are transferred, and one part is supplied to the next process from the end of the track.
In this case, it is usually required to be supplied in a constant posture. For this purpose, various sorting devices have been developed depending on the shape and properties of the parts to be supplied.
For the parts 1 shown in FIGS. 1 and 2, either no sorting action is performed or the sorting efficiency is very low. That is, the part 1 shown in FIGS. 1 and 2
is a mini-mold transistor, and a base electrode 1c is attached to one side, and an emitter electrode 1a and a collector electrode 1b are attached to the other side. These parts are extremely small parts, and a large amount of them are thrown into the bowl. It has been impossible or insufficient to feed these parts 1 along the transfer path 2 in the direction of the arrow in the orientation shown in FIG. 1 using conventional sorting devices.

Note that Japanese Patent Application Laid-Open No. 151420/1983 discloses a configuration for sorting the left and right side surfaces of small parts similar to those shown in Figs. The transmission efficiency is low, and bending of the electrodes may cause clogging of parts.

[Effect]

Processing is simple because it is only necessary to provide a transfer path for sorting as a mere plane with a predetermined width and an upper wall forming member at a predetermined distance from the transfer path, and to form cutouts of a predetermined width at predetermined pitches in this. One first protrusion on one long side of the dovetail rectangular body, and a plurality of second protrusions on the other side opposite to the one side.
It is possible to sort the left and right sides and the front and back of the parts provided by shifting the protruding part toward the upper surface of the body, and the other side of the sorting transfer path can be left as a free space, so that the first part of the parts can be sorted. 1. Even if the second protrusion is slightly bent, no clogging occurs, and the efficiency of sorting parts can be extremely high.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS A parts feeder equipped with a parts sorting device according to an embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, the parts feeder as a whole is indicated by 3, and a spiral track 4 is formed inside the ball 40, which is wound clockwise. A feeding device 5 is provided, to which a reversing chute 6 is connected. The reversing chute 6 is further connected to an electrode feeder 7 for feeding the parts 1 arranged in a desired posture to the next process one by one. This electrode feeder 7 has a transfer path 8 as shown in FIG. 8, is supplied to an electromagnet drive section 9 by a leaf spring 10 as shown in FIG. Component 1 is supplied to the next process. The entire electrode vibrating feeder 7 is supported on a foundation by a vibration isolating rubber 13.

The parts feeder 3 is also driven by an electromagnetic drive section built into the casing 11, and as is well known, a plurality of plate springs arranged at equal angular intervals in an inclined manner generate torsional vibration force, which is applied to the ball 40. The entire parts feeder 3 is supported on a foundation by a vibration isolating rubber 12.

Although not shown in FIG. 3, the component 1 is transferred along the spiral track 4 while being subjected to torsional vibration force, and reaches the component sorting device 5. In this introduction part, a notch 4a is formed in the track 4, so that the transfer path 21A in the parts sorting device 5 is connected to the track 4 as shown in FIG.
It is narrowed to about half the width of the This transfer path 21
An upper wall forming member 20 is fixed to the upper part of the side wall portion 21 forming A, and arcuate cutouts or grooves 22 having a width A are formed at equal intervals B in this upper wall forming member 20. There is. The width A of the groove 22 is part 1
The groove 2 is larger than the width a of the electrodes 1a, 1b, 1c.
2 interval B is larger than the distance b between emitter electrode 1a and collector electrode 1b of component 1. Also, the transfer path 21A
As shown in FIG.
The distance up to this point is configured to be slightly larger than the height of the component 1. On the transfer path 21A, the center of gravity G of the part 1
is slightly outward from the edge 21a of the transfer path 21A (in the direction of the center of the ball 40), and the depth of the groove 22 is the same as when the component 1 makes a reversal motion along the trajectory R with the edge 21a as a fulcrum. The size is such that it does not interfere with this.

As is clear from FIG. 5, the transfer path 21A is inclined downward to one side with respect to the direction of transfer of the component 1, but the center of gravity G of the entire component 1 is at the edge 21 on the other side.
This is a small-width sorting transfer path located outward from point a.

In the above-mentioned transfer path 8 of the electrode feeder 7, as shown in FIG.
31 is fixed by bolts 33 and 34,
With this, the configuration is such that the attitude of the component 1 is regulated. The reversing chute 6 is formed in an arc shape as shown in FIG.
It is equipped with a transfer path with a cross-sectional shape similar to that of .

The embodiment of the present invention is configured as described above,
Next, this effect will be explained. In each figure, the dimensional ratio of each part is drawn to be different from the actual size in order to make the figure easier to understand.

In FIG. 6, when the base electrode 1c reaches the groove 22 of the upper wall forming member 20, the component 1', which has been transferred with the base electrode 1c facing the side wall part 21, like the front component 1', Once fitted, the part 1' rotates in the direction indicated by the arrow using the edge 21a of the transfer path 21A as a fulcrum, and falls into the inside of the ball 40. In addition, since a plurality of grooves 22 are provided in the upper wall forming member 20, the state of transport of parts,
Groove 22 where base electrode 1c of component 1' is located due to some reason such as non-uniform vibration or interaction between components
Even if it does not fit into the next groove 22,
Or it fits into the groove 22 after this. However, when a large number of parts are loaded into the ball 40 and transferred under ideal conditions, only one groove 22 is used.
All you have to do is form the . It is clear that even if the electrodes 1a and 1c of the component 1' are bent to some extent, this does not affect the left/right orientation selection.

In FIG. 6, like the rear part 1, the part 1 that has been transferred with its emitter electrode 1a and collector electrode 1b side facing the side wall 21 has its emitter electrode 1
Even if the collector electrode 1b reaches the groove 22,
Since the other electrode 1b or 1a is supported by a portion of the upper wall forming member 20 other than the groove 22, the emitter electrode 1a or the collector electrode 1b does not fit into the groove 22, and the component 1 moves forward as it is. Even in this position of the component 1, as long as the electrodes 1a and 1b are not bent so as to fit into the grooves 22, the position selection will not be impaired in any way.

The above description has been about the parts 1 and 1' that have been transferred with the electrodes 1a, 1b, and 1c facing upward, but as shown in FIG.
The component 1'' that has been transferred with the side facing downward, that is, the component 1'' facing down, rotates counterclockwise about the edge 21a of the transfer path 21A as a fulcrum, and the electrodes 1a, 1
Since b and 1c are eccentrically provided on the upper surface side of the body, they pass below the upper wall forming member 20 and fall into the inside of the ball 40 without coming into contact with the upper wall forming member 20.
(In FIG. 7, the distance from the edge 21a to the tip of the electrode 1c is from the transfer path 21A to the upper wall forming member 20.
(as it is sufficiently small compared to the distance to). Further, the parts 1 that have been transferred with their longitudinal direction oriented laterally with respect to the transfer direction may fall inside the ball 40 before reaching the parts sorting device 5. Although the case where the component 1 is transported on the path 21A with its longitudinal direction facing the transport direction has been described, the case where the component 1 is transported in a direction perpendicular to the longitudinal direction, that is, with its width direction facing the transport direction, has been described. Even if a component is introduced into the transfer path 21A, the transfer path 21A is inclined downward in the radial direction as shown in FIG. It receives a correction action that directs it in the direction of transport. Thereby, the ability to supply parts in a predetermined posture can be improved.

That is, the center of gravity G of the component 1 is located outside the transfer path 21A, but since the longitudinal direction of the component 1 is generally inclined to either side with respect to the transfer direction, the center of gravity G of the component 1 is tilted toward the side wall with a small jump due to vibration. Part 2
A force acts to direct the paper toward the first side, thereby directing its longitudinal direction toward the transport direction. There are no elements that prevent this. Note that in the case of torsional vibration as in this embodiment, centrifugal force acts, so this effect is further strengthened.

The component 1 that has been transferred in a posture similar to the rear component 1 in FIG. 6 is reversed within the reversing chute 6 as it is transferred, and is supplied to the electrode feeder 7 in the state shown in FIG. In the electrode feeder 7, the component 1 is transferred while being regulated to a desired posture as shown in FIG.

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

For example, in the above embodiment, there is a base electrode 1 on one side.
c Emitter electrode 1a and collector electrode 1 on the other side
Although the mini-mold transistor 1 having the shape b has been described as a component, it generally has one first protrusion on one long side of the body having a substantially rectangular shape, and a plurality of first protrusions on the other side opposite to the one side. The present invention can be applied to a component having a second protrusion deviated toward the upper surface of the body.

Further, in the above embodiment, the arcuate groove 22 is formed in the upper wall forming member 20, but a slit-shaped notch may be formed instead. In other words, the upper wall forming member 20 may be formed with comb-tooth-shaped notches at equal intervals.

Further, in the above embodiments, a parts feeder having a spiral track has been described, but the present invention can also be applied to a so-called linear parts feeder having a straight track.

[Effect of idea]

As described above, in the parts sorting device for the vibrating parts feeder of the present invention, in which the parts on the transfer path are transferred by vibration, the parts to be sorted are A rectangular body has one first protrusion on one long-side side, and a plurality of second protrusions on the other side opposite to the one side, which are offset toward the upper surface of the body. a small-width sorting transport path that is inclined downwardly on one side with respect to the transport direction of the parts, and the entire center of gravity of the parts is located outward from the edge on the other side;
a side wall formed on the one side of the transfer path; an upper wall forming member that is spaced from the transfer path by a distance slightly greater than the height of the component and extends along the transfer path; The wall forming member has a width larger than the width of the first protrusion of the component, and the plurality of second protrusions are provided in the wall forming member.
It consists of a plurality of notches formed with pitches different from the pitch of the protruding part, and the parts that are facing upward and are transferred with the one side facing the one side of the sorting transfer path are Since the center of gravity of the whole is located outward from the other side edge of the sorting transfer path, the first protrusion passes through the notch due to the reversing action of the gravity at that edge, and the first protrusion passes through the notch. At least one of the plurality of second projections is removed from the transfer path downward, and the parts transferred with the other side facing the one side of the sorting transfer path have at least one of the plurality of second protrusions While being pressed against the wall-forming member by the force of the center of gravity at the edge of the sorting transfer path, the parts are passed through the transfer path, and the parts are turned face down with their longitudinal direction facing the transfer direction. Since the center of gravity of the entire body is located outward from the edge of the sorting transfer path, the first protrusion or the second protrusion is caused by the reversal action of the gravity at the edge of the upper wall forming member. Since it passes below and is removed from the sorting transfer path, it is possible to sort the front and back sides and left and right sides of the parts, and the above parts can be efficiently and reliably sorted and transported in the desired posture. . In addition, it requires fewer members, has a simple structure, and is easy to process, and even if the protruding parts of the parts are bent, parts that are not in a predetermined posture can be reliably and quickly sorted or removed. Furthermore, the ability to feed parts can also be improved by a straightening action that orients the longitudinal direction of the parts to the transport direction.
