are installed consecutively.

The return trough I2D and the supply trough are each connected to a common leaf spring support portion by a pair of front and rear driving leaf springs tt:ac3υ. The leaf spring 6υc37J is arranged to be inclined in opposite directions, and both ends are connected to the trough n (
2υ and is fixed at the leaf spring support part.

A movable core C/υ is fixed with a bolt to one trough, and a movable core C/υ is similarly fixed to the other trough (211) with a bolt.
An electromagnetic core (A) is located between 3 and 3 and fixed to the opening of the leaf spring support portion. Electromagnet core □□□ both 1111

Therefore, the movable core diagram (the directions of the AC attraction force to the candle are in opposite directions).
The vibrating part and the round plate spring G11 (32) disposed as shown in the figure connect both troughs I2.
3 (211) are in opposite phases and tilt in directions opposite to each other as shown by arrows A and B.

In this embodiment, the return trough side movable part including the parts discharge part I241 and the supply trough machine side movable part have the same mass, and the mass of the spring support part (to) is equal to the sum of these parts. It is configured. Therefore, the return trough circle and the supply trough ■ are respectively moved in the directions of arrows B and A with the same trough, and the parts in the supply trough are transferred in the direction shown by the arrows.
It slopes and then ascends the transfer surface (221) to reach the flat surface. At this point, the return trough 12 is guided by the guide section (■).
Move to the 11th side.

Each transfer surface 1261□□□ of the return trough Cυ is horizontal but has a step, and one transfer surface (29) is low and at the same level as the left end of the transfer surface t23 of the supply trough.

The other transfer surface is outwardly and slightly downwardly inclined, and the parts are transferred biased toward the side wall (23a). t'fc
, above the transfer surface ω, there is provided a parts sorting section ( ), but this is not particularly relevant to the present invention, so it is shown in a simplified manner.

It falls onto the top and circulates through the return trough (211) and the supply trough. ■ is a bulkhead fixed to the top Qυ.

In addition, the above-mentioned spring support part cost is arranged below nine bases (40, vibration isolating leaf springs (43a) (43h) (44a
) (44h). Leaf spring (43a) (4
3b) (44a) (44h) are fixed to the spring support part q and the base (4) with bolts t4s 14.61 t4η4 at both ends, respectively.The base (4Q is fixed to the installation base with bolts) . Anti-vibration leaf spring (43a) and (4
3h), and spacer +4 between (44a) and (44b)! J51 and 511 (53) are interposed, thereby maintaining a predetermined distance fc between these upper and lower leaf springs. By arranging the leaf springs in this manner, the leaf springs (43a
) (43b), (44a), and (44h) can have sufficiently large bending rigidity in the lateral direction with respect to the longitudinal direction (horizontal direction in the figure). Base (40 through holes +4 on both ends)

When the electromagnetic coil Gη■ is excited, the supply trough T2z and the return trough Qυ are moved as described above, and their reaction force is applied to the spring support portion via the driving leaf spring 61C32. However, the amplitudes of the supply trough and the return trough (211) are the same, but since the imaging is in opposite phases, the horizontal components cancel each other out, and the vertical components are phase-added. 44h)
Due to this vertical ash reaction force, the bolt is 61t4η
The fixed end is used as a fulcrum for bending motion, thereby providing vibration isolation to the installation base.

Next, the component transfer path height adjusting device (a) provided in the component discharge section C241 will be explained.

The parts discharge section (24 is composed of a transfer path forming block field integrally fixed to the return trough (2υ), and as shown in FIGS. 3 to 5, there is a linear groove-shaped transfer path 67. ) is formed.A part transfer path height adjustment device (67) is provided above the transfer path (67).

It is configured so that The transfer path (six road surfaces or bottom surfaces and the component mounting surface (63a) of the block field are parallel to each other. The same applies to the other height adjustment section.

Installation push field 61. The integrated assembly consisting of the height-limiting frame is fixed to the block by means of mounting screws 6 to 9. That is, as shown in FIGS. The other mounting screws (same for 641&"j) are inserted through the elongated hole (62h) of the height regulating plate (67J) and the hole (75a) of the spacer 17E9, and are screwed into the screw hole (70a) of the fixed block q■. It is fixed to the fixed block (7α is the pusher fR3 with the bolt συ).As shown in Figure 3, the mounting block (61 is formed integrally with the block 1 mark and the next side wall part (7 It comes into contact with a vertical surface, but it does not necessarily have to come into contact with it.

The first embodiment of the present invention is configured as described above, and its operation, effects, etc. will be explained next.

First, when using this feeder 4, the parts to be fed 1
The same part m' is the mounting block + of the height adjustment part I6υ
6Fj and a block 16 for forming a transfer path. That is, the mounting screw G4 tta is loosened,
The height regulating plate (621) is movable up and down.The mounting plate A7+6811 which is integral with this plate is also movable up and down.

A part m' that is the same as the part m to be supplied is a block (63)
is placed on the component mounting surface (63a) of. Place the lower surface (68b) of the mounting block on this part m', and in this state, tighten the mounting screw fH+65716Gl onto the fixing block Oy.
When tightened against fcl, a predetermined gap S is formed between the lower surface of the height regulating plate +b7J and the upper part m at the transfer path (6).

Note that by providing two height adjustment portions t616υ, more uniform formation of the gap S is ensured.

Although not shown, a large number of parts m are put into the trough (211+23).When the electric stone coil 13η is excited, the trough f211 (23 vibrates in the directions of arrows B and A, and the part m is shown in FIG. In the component sorting section (c), for example, the overlap of components m is removed, and the horizontal component rrL (for example, a rectangular plate-shaped chip resistor) is turned into a valley bottom. The part m on the transfer surface is guided again to the supply trough.The sorted part layer is guided to the six transfer paths of the part discharge section +241. rrL is height regulation plate +6
'lIK is prevented from jumping significantly upwards, and rotation in the horizontal plane is also prevented by the side walls of the transfer path (6η).In other words, while maintaining a predetermined posture, the transfer path "167 ] will be transferred over the top.m2
The height regulating plate 162 prevents the parts m from overlapping each other during transport.E, the parts m are supplied one by one to the next machine in a predetermined posture from the end of the part discharge section.

When the type of parts to be supplied changes, VCil''11.
The mounting screws are loosened, component m' is removed, and the next component is placed on the component mounting surface (6) of block S3 instead.
3a) Place on top. Incidentally, when supplying the above-mentioned part m, the part m' may be extracted after the height is adjusted.

If the following parts are interposed and the mounting screws 1641 to 1661 are tightened, a predetermined gap S will be formed between the transfer path (6 parts above) and the height regulating plate &3. When supplying parts, it is assumed that the previous 111 parts m are completely removed from the main feeder (4).

As mentioned above, according to this embodiment, even if the type of parts changes, the height of the transfer path can be adjusted very easily to obtain a predetermined gap S.

It is sufficient to simply clamp the parts to be supplied between the mounting blocks. Furthermore, even if the type of component m changes, the gap S can be kept constant.

6 and 7 show a second embodiment of the invention.

In the above embodiments, a so-called linear parts feeder will be explained, and in this embodiment, a spiral parts feeder or simply a wiper in a parts feeder will be explained.

In FIG. 6, a spiral track (8υ) is formed within the ball (801). The wiper member z is fixed to a part unit integral with the pole field by Gerd (Incorporated).

The component mounting surface (83a) of the body part and the road surface of the truck are parallel, but the component mounting surface (83a) is higher by a size of 8. The same part m' as the part m to be supplied
By holding the wiper (83) between the pole and the part and tightening the screw, a predetermined gap S is formed between the wiper i82 and the part m on the track 8υ.The part m is the pole It is transferred in the direction of the arrow under the torsional vibration of 8α, and if there is an overlapping component m, it is removed by the wiper t&5.In other words, the component rrL is brought into a single layer state by the wiper z.

Even in this embodiment, when the type of parts changes, it is sufficient to simply replace the parts to be clamped, and no troublesome adjustment work is required.

Although each embodiment of the present invention has 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 embodiment, the upper wall forming member is composed of the height regulating plate 63 and the mounting block (enclosure), but these may be formed into one piece.

The upper wall forming member may also have a cross-sectional shape (member 6316110 (combined 61)) as shown in FIG. In this case, the component m' is held between the horizontal arm portion and the mounting surface (63a) of the block (63I).This horizontal arm portion extends above the multi-feed path 1671. The tip of the transfer path tli7 may be bent toward the road surface of the transfer path tli7. Alternatively, a configuration as shown in FIGS. 6 and 7 may be simply applied.

〔Effect of the invention〕

As described above, according to the component transfer path height adjusting device in the vibrating component feeder of the present invention, even if the types of components handled change, the posture of the components can be maintained according to the component.
Alternatively, the height of the conveying path for single-layer conveying can be adjusted very easily. This effect is particularly noticeable when the component is small, such as an electronic component.
