Description

[Detailed description of the invention] The present invention relates to a vibrating multi-row component feeder.

Conventionally, so-called parts feeders have been widely used to sort and feed parts one by one. This parts feeder has a bowl-shaped container equipped with a spiral track, and by applying torsional vibration to this container, the parts inside the container are transferred upward on the track. During this transfer process, the parts are sorted by a sorting means provided on the truck or in the vicinity of the truck, and the parts that are not sorted are dropped to the center bottom of the container or to a lower track. The delivered parts will be sent to one person.
The parts are discharged from the container, but if there is only one track, the parts are only fed one by one from the parts feeder to the subsequent process, resulting in poor work efficiency. To deal with this, a parts feeder with multiple rows of tracks in a single bowl-shaped container has been developed, but this requires a lot of curved machining, resulting in problems such as poor machining efficiency. . In addition, the parts feeder applies well-known torsional vibration to the bowl-shaped container, but the tracks closer to the outer periphery have a larger amplitude and therefore the parts can be transferred at a faster speed. There is also the problem that an unbalance occurs in the speed, and the overall feeding speed cannot be improved much.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a vibrating multi-row component feeder that hardly requires curve processing and can feed parts from each row at approximately the same feeding speed. purpose. This purpose, according to the invention, consists of a supply trough which extends linearly and is subjected to vibrations so as to transport the parts in one direction; A parts sorting section consisting of a plurality of sorting tracks that are subjected to vibrations and each equipped with a sorting means and an opening for removing non-sorted parts; an integrally provided below this parts sorting section, each of the openings and the A parts receiving part communicating with the supply end of the supply trough; proximate to the supply trough and integrally fixed to the parts sorting part; a parts distribution section comprising a plurality of distribution tracks extending radially so as to be connected to the supply end of each of the shunting tracks; the parts discharged from the discharge end of the supply trough are connected to the plurality of distribution tracks; The parts are guided to the starting end of the track and distributed to a plurality of sorting trucks of the parts sorting section, and the parts that are not in a predetermined sorting state while being transferred by these sorting trucks fall through the opening and into the parts receiving section. The vibrating multi-row component is characterized in that the parts are guided to the supply end of the supply track and the parts sorted on each of the sorting tracks are discharged from the sorting track one by one. feeding machine,

Although not shown, the currents to the coils of the electromagnets 15 and 24 are controlled by separate controllers, and the supply trough 1 and the mutually integrated component distribution section 2, component transfer section 3, and component receiving section 4 are controlled by separate controllers. For example, it can be vibrated with a vibration stroke of about 0.5 mm.

An opening 27 communicating with the vibration receiver 4 is formed at the right end of the inner side wall 26 of the supply trough 1 in FIGS. 1 and 4, and this right end serves as a component supply end. The feed trough 1 has a transfer surface 28 inclined upwardly from the feed end at, for example, 3.5 degrees, which is articulated with a horizontal surface 29 at the left end. Transfer surface 2

The parts distribution section 2 has five rows of distribution tracks 31, 3.
2, 33, 34, and 35 are formed radially from the starting end 38 so as to be connected to each track of the parts sorting section 3, which will be described later.As shown in FIG. A downward slope (e.g. 8 degrees) to the left in terms of direction (to the right in Figure 5)
are doing. Therefore, the part m is connected to each track 32 to 3.
The parts are transferred toward the parts sorting section 3 so as to be biased towards the side walls 32a to 35a or the protruding wall part 36 of the parts. The distribution tracks 32-35 are also inclined slightly upward (eg, 2 degrees) in the direction of transport.

Five parallel rows of sorting tracks 4 are provided in the parts sorting section 3.
0, 41, 42, 43, and 44 are formed, and these transfer surfaces are inclined downwardly to the left (to the right in FIG. 6) with respect to the transfer direction of the part m, as shown in FIG. Therefore, part m is attached to each track 4.

It is transferred to the right side in FIG. As clearly shown in FIG. 1, the discharge end of each of the tracks 31 to 35 of the parts distributing section 2 is located on the right side (in FIG. are connected in a staggered manner (towards the bottom), which allows the large number of parts m to flow smoothly. Even if it is not shown in the figure, parts m are distributed on the distribution tracks 31 to 35 at high density.
When the parts m are transferred, the parts m are supplied from the distribution tracks 31 to 35 to each of the tracks 40 to 44 of the parts sorting section 3 in multiple rows and in an overlapping state. If this is not done, there is a risk that the pushing force between the parts m will become stronger due to the transfer force, and the parts m will no longer flow smoothly.

Near the feed end of each shunting track 40-44, an elongated stepped opening 46-50 is formed along its transfer surface and communicates with the component receiving portion 4, which will be described in more detail below. The stepped openings 46 to 50 are narrow openings 51
~ 55 and wide openings 56 to 60, which allow parts to be moved along the narrow openings 51 to 55 in the distribution tracks 40 to 44, but smaller than the length of the part m (3.2 mm in the example), but wider than the width. A large width track is formed as shown in FIGS. 7A and 7B, and a narrow track portion 40 is formed along the wide openings 56-60 as shown in FIGS. 8A and 8B.

Grooves 40c to 44c are formed from the right end portions 6 to 60 to the discharge ends of the transfer tracks 40 to 44, which are connected to the narrow track portions 40b to 44b. The width of these grooves 40c to 44c is sufficiently larger than the width of component m, for example, 1.9 mm. Also, the depth is part m

In FIG. 1, the left edge of the holding plate 62 is slightly inclined from the direction perpendicular to the transport direction of the part m, and as a result, the left edge of the holding plate 62 is slightly inclined from the direction perpendicular to the transport direction of the part m.
to facilitate the fall into the openings 46-50.

Next, the component receiving section 4 fixed to the lower part of the component sorting section 3 will be explained with reference to FIGS. 9A and 9B.

The component receiving portion 4 has mounting portions 63 and 65 whose upper surfaces are horizontal, and the screw holes or through holes provided in these portions are used to attach the component receiving portion 4 to the upper component sorting portion 3 and the lower first coupling plate 17. Fixed. A slope 64 that slopes downward toward the side wall 66 is formed between the attachment parts 63 and 65, and an opening 67 is formed between the side wall 66 and the attachment part 63. This opening 6
7 is aligned with the opening 27 of the supply trough 1 described above.

The vibrating component feeder according to the first embodiment of the present invention is constructed as described above, and its operation will be explained below.

First, a large number of components (for example, chip capacitors) m to be arranged and supplied are supplied onto the supply trough 1 or the component distribution section 2 and component sorting section 3. When power is applied to the drive parts 7 and 9, the supply trough 1 vibrates in the direction of arrow b as shown in FIG.
The component feeding section 3 and the component receiving section vibrate in the direction of arrow a. As a result, the part m in the supply trough 1 is
In the figure, it rises on the transfer surface 28 to the left and reaches the horizontal surface portion 29. Guide part 30 here
a toward the opening 37 side, and is also guided by a stopper member 39 fixed to a corner of the component distribution section 2 to the starting end 38 of the distribution tracks 31 to 35. From here, the distribution tracks 31 to 35 lead to the sorting tracks 40 to 44 of the parts sorting section 3.
Since the large amount of parts m supplied to the starting end 38, which corresponds to the corner of the fan, is distributed almost equally to each of the distribution tracks 31 to 35, each part m is Each distribution truck 31~
35 to the right in FIG. 1 at approximately the same density. As shown in FIG.
- 35 are biased toward the side walls 32a to 35a or the protruding wall 36, and are transferred to the supply ends of the sorting tracks 40 to 44 of the parts sorting section 3.

On each of the sorting tracks 40 to 44 of the parts sorting section 3, the part m is transferred to the track 41 as shown in FIG.
-44 side wall parts 41a-44a or protruding wall 4
It is transferred to the 5th side. Until reaching the openings 46 to 50, a large number of parts m are transferred in multiple rows and overlapping on each track 40 to 44.
At this point, the side walls 41a of the tracks 41 to 44
44a or the parts m in the row that is in contact with the protruding wall 45, that is, the leftmost row in the transport direction, are transported on the narrow transport surface (hereinafter referred to as the intermediate track section), and the parts m in the other rows are opened. 46-5
0 and falls into the component receiving section 4.

In this embodiment, the conveying state is defined as transporting the parts m in a single layer in a reclining position with the longitudinal direction of the parts facing the transport direction, but on the intermediate track, the longitudinal direction is perpendicular to the transport direction. There are parts m that are transferred in a posture facing the direction (see FIG. 7B), and there are also parts m that are overlapped although in a single row. However, the overlapping parts m on the middle tracks of the transfer tracks 42, 43, 44 are wiper 61 (No. 8B
), the transfer is obstructed and the opening 4
8, 49, and 50 and fall into the component receiving section 4.

Next, each part m reaches the narrow track portions 40b to 44b of the shuffling tracks 40 to 44, where it reaches the eighth part m.
As shown in Figure B, the component m in a posture with its longitudinal direction perpendicular to the transport direction falls into the wide openings 56 to 60 due to the action of gravity. Further, the parts m overlapping on the narrow width tracks 40b, 41b of the shuffling tracks 40, 41 are dropped into the wide width openings 56, 57 by the wiper 61.

As described above, the narrow track portions 40b to 44 are
The part m is sorted and transferred on the top b, but depending on the transfer speed of the part m and the pressing force between the parts m, the part m may be moved again by the time it reaches the edge 62a of the holding plate 62. It is possible that they overlap. However, even if the parts m overlap, they are guided by the edge 62a of the holding plate 62 and fall into the openings 46-50. Therefore, each part m is reliably transferred in a single layer in a single row under the holding plate 62 in a predetermined posture.
Eventually, they enter the grooves 40c to 44c, are transferred, and are discharged one by one from the discharge ends of the sorting trucks 40 to 44, leading to a subsequent process (not shown).

On the other hand, the parts m that have fallen into the part receiving part 4 through the openings 46 to 50 are transferred toward the side wall part 66 along the inclined surface 64 under the action of gravity and the vibration force, and some parts m directly fall into the opening. 67, and a certain part m receives vibrational force along the side wall part 66 and moves to No. 9A.
It is transferred to the right in the figure and reaches the opening 67.
The part m is guided through the opening 67 by the inclined surface 64 and the inclined surface of the mounting member 63, and the part m is guided into the supply trough 1.
through an opening 27 in the feed end. From now on, each part m will again be subjected to the same action as described above. The non-separated parts m are circulated in the order of supply trough 1 -> parts distribution part 2 -> openings 46 to 50 of parts sorting part 3 -> parts receiving part 4 -> supply trough 1.

As described above, in this embodiment, a large amount of parts m is almost equally distributed by the parts distributing section 2 to each of the sorting tracks 40 to 45 of the parts sorting section 3. From then on, the parts m are supplied to the subsequent process at a substantially uniform supply speed. Therefore, the amount of parts m remaining in the parts feeder can be extremely reduced at the time when parts m are no longer discharged from the discharge end of each of the tracks 40 to 49 at a substantially uniform supply speed. In other words, parts m are fed from each shunting truck 40 to 44 at a desired feeding speed until the amount of parts m remaining in the parts feeder becomes extremely small. This is extremely effective when managing parts m in lots.

This embodiment has a structure in which two component feeders having substantially the same configuration as the five-row component feeder according to the first embodiment are integrally coupled symmetrically with respect to the transfer direction. Therefore, since the details of each part are the same as those in the first embodiment, a description thereof will be omitted.

That is, in this embodiment, supply troughs 1A and 1B having the same configuration as in the first embodiment are provided symmetrically with respect to the transfer direction, and a sub base 10 is fixed on a base 105 supported on the foundation by a vibration isolating rubber 106.

That is, the press plate 71 is fixed so as to cover the ends of the wide openings 56A, 57A or a part thereof and the grooves 40Ac and 41Ac, and the press plate 72 is fixed so as to cover the ends of the wide openings 58A, 59A or a part thereof. and the grooves 42Ac and 43Ac. These presser plates 7
In FIG. 10 of 1,72, the left side edge is inclined to the right with respect to the transport direction and serves to guide the unadjusted parts m into the wide openings 56A, 57A, 58A, 59A.

Further, the holding plate 73 is fixed so as to cover part of the ends of the wide openings 60A and 60B and the grooves 44Ac and 44Bc, and its left side edge is inclined in a V-shape, so that it can be kept in the regular feeding state. There is no part m in the wide opening 60

It may be coated with Bc. However, using five presser plates 71 to 75 can reduce the overall weight, and as is clear from comparing Figures 1 and 10, the slope of the edges can be made larger. Therefore, the guiding effect into the wide openings 56A to 60A and 56B to 60B becomes stronger.

As shown in FIGS. 10 and 16, the stepped opening 4
Wiper plates 61A and 61B are provided above so as to diagonally cross 6A to 50A and 46B to 50B.

Although the vibration + row component feeder according to the second embodiment is constructed as described above, its operation is almost the same as that of the first embodiment, so a brief explanation will be given below.

Vibration drive parts 107A, 107B and 109A,
When power is applied to 109B, the supply troughs 1A and 1B vibrate in the direction of arrow b as shown in FIG. It vibrates in the a direction. Therefore, the parts m in the supply troughs 1A, 1B
(not shown in the second embodiment) is transferred to the left as shown by the arrow in FIG. Receives transport force. Parts m in the supply troughs 1A and 1B are guide parts 30Aa and 30
Ba and guided to the starting ends 38A, 38B of the component distribution sections 2A, 2B, where a large amount of components m
are each distribution track 31A-35A and 31B-3
5B, these tracks 31
A to 35A and 31B to 35B are transferred in the direction indicated by the arrow.

Distribution tracks 31A, 35A and 31B-35
B to parts sorting truck 5 of parts sorting sections 3A and 3B
The parts m transferred to parts 1A to 55A and 51B to 55B, respectively, are transferred to the parts sorting section 3A in a biased manner to the left side in the transfer direction, and are transferred to the parts sorting section 3B.
In this case, it is shifted to the right side. The overlap of parts m is removed by wiper plates 61A and 61B,
Width track part 40Ab~44Ab and 40Bb~
44Bb, the parts m facing sideways with respect to the transfer direction fall into the wide openings 56A to 60A and 56B to 60B, and each part m is placed in a single layer with the longitudinal direction facing the transfer direction and is placed on the edge of the holding plate 71 to 75. reach the position of the department.
Depending on the transfer speed and the pushing force between the parts m, or the transfer distance after passing through the wipers 61A and 61B (especially considering the narrow track portions 44Ab and 44Bb), after the parts become a single layer, Although it is possible that they will overlap again, the presser plates 71 to 7
The beveled edges of 5 allow these to be easily guided into the wide openings 56A-60A and 56B-60B, ensuring that each part m is in the groove 40 in a single layer and in the prescribed position.
Guided within Ac~44Ac and 40Bc~44Bc,
One piece is discharged outward from the discharge end.

On the other hand, the parts m that have fallen into the stepped openings 46A to 50A reach the slope 164A of the parts receiving part 104,
It is guided to the opening 167A under the effect of gravity and vibrational force. Further, the parts m that have fallen into the stepped openings 46B to 50B reach the slope 164B of the component receiving part 104, and are similarly guided to the other opening 167B. From the openings 167A and 167B, the mounting portion 16
Due to the guiding action of the sloping sides of the parts m, the parts m pass through the openings 27A, 27B of the feed tracks 1A, 1B to their feed ends. From here, it is transferred to the left side in FIG. 10 on the upwardly inclined transfer surfaces 28A, 28B of the supply trucks 1A, 1B, and passes through the discharge side openings 37A, 38B to the distribution tracks 31A to 3.
Starting ends 38A and 38B of 5A and 31B to 35B
leading to. Hereinafter, in the same manner as described above, the parts m that are not in the non-sorting state are from the parts distribution parts 2A, 2B to the parts sorting part 3.
A, 3B → Component receiving part 104 → Supply trough 1A, 1
It is circulated with B.

In this embodiment, similarly to the first embodiment, the starting end 38A,
Distribution tracks 31A~ extending radially from 38B
A large number of parts m by 35A and 31B~35B
Since the components m are almost uniformly distributed onto the respective tracks 40A to 44A and 40B to 44B of the component sorting sections 3A and 3B, the components m are discharged from these discharge ends at approximately the same supply speed. That is, the part m can be supplied to the subsequent process from all the trucks 40A to 44A and 40B to 44B at approximately the same supply speed until the remaining amount of the part m in the feeder becomes almost zero. As described in the first embodiment, this is extremely effective when lot management is performed using parts m.

As mentioned above, the structure of the second embodiment is almost the same as that of the first embodiment.
Although the structure of the embodiment is an integrated structure with a structure configured symmetrically with respect to the transfer direction, the feeder as a whole is configured symmetrically with respect to the center line C-C. In terms of vibration balance, the first
It can be said that it is easier to design than the example. Of course, in the first embodiment as well, the vibration balance can be easily adjusted by attaching balance weights at appropriate locations.

Furthermore, in both the first and second embodiments, most of the constituent parts are made of aluminum to reduce their weight, but handles are attached to both sides of the bases 5 and 105, although not shown. It has a structure that is convenient to carry. Also, the drive parts 7, 9
107A, 107B, 109A, and 109B, it is normal to have a cover fixed to the bases 5 and 105 so as to cover the components 107A, 107B, 109A, and 109B. The second embodiment can have a more compact configuration as a whole. Further, in the second embodiment, two drive units 10 are used to drive the component distribution units 2A, 2B, the component sorting units 3A, 3B, and the component receiving unit 104.
7A and 107B were used, but they may be driven by a single drive unit.

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

For example, in the above embodiments, the number of rows of distribution tracks and sorting tracks is 5 or 10, but of course the number is not limited to these.

Furthermore, in the above embodiments, the feeding means in the parts feeding section is a narrow track section or a wiper plate, and almost rectangular electronic components are to be fed, but the present invention is not limited to these, and can be applied to conventional parts feeders. Various sorting means can be applied to the present invention depending on the parts to be sorted.

Since the vibrating multi-row parts feeder of the present invention is configured as described above, it is not only easier to process than conventional multi-row parts feeders, but also parts are fed from each row at approximately the same feeding speed. can be done.
