The sixth block 85 has a cross-sectional shape as a whole as shown in FIG. 23, but has a notch 85a on its downstream side which is inclined downward toward the vibrating parts feeder 33 as clearly shown in FIGS.

I have. By removing one of the spacers 86 and 87 or changing it to another spacer, the size of the gap s as the above-described air ejection port is adjusted. As shown in FIG. 3, two component front and back posture detecting devices 88 are arranged in parallel.

Next, the component posture holding unit 102 located at the most downstream part of the linear vibration feeder 34 will be described with reference to FIGS.
This will be described with reference to FIG. In the figure, a seventh block 97 and an eighth block 96 are fixed to the common mounting block 41 by screws 95 and 95 '. Further, the seventh block 97 has an L-shaped notch.
The tunnel-like track T is formed by combining the eighth blocks 96 via the zeros as shown. As shown in FIG. 1, this is a track for transferring all the minute components C face up and moving the longitudinal direction in the transfer direction. Although the cross section of such a track T is very small, each of the blocks 96 and 97 can easily perform precision processing for precisely forming the track T, and by combining them, a minute component C can be formed. A track T that passes through the track T without stagnation. The spacer 100 is provided to finely adjust the height of the track T.
In addition, the positioning plate 101 is fixed to the block 97 by a screw n. With this, the positioning of the block 97 with respect to the common mounting block 41 is performed in the longitudinal direction.

As shown in FIG. 26, the width of the common mounting block 41 is enlarged at the right end in FIG. 2. The leaf spring mounting block to which the upper ends of the pair of front and rear leaf springs are fixed as described above. 42 is fixed. The light emitting device 104a and the light receiving device 104b are mounted via the mounting blocks 106a and 106b. These are vertically opposed to each other in accordance with the notches 96a and 97a as the light transmitting holes formed in the eighth block 96 and the ninth block 97, and detect the presence or absence of the component C of the track T. Thereby, the overflow state and the closed state of the component C in the track T are monitored.

The configuration of the embodiment of the present invention has been described above. Next, this operation will be described.

In FIG. 2, when a drive current of a higher frequency is supplied from the inverter to the electromagnet 36, a magnetic attraction force is generated, and the bowl 39 performs torsional vibration as is well known. In the bowl 39, a large amount of the micro component C shown in FIG. 1 is stored. It is sequentially raised along a spiral track 40 and transported counterclockwise in FIG. An arc-shaped ejection track 59 is formed at the ejection end, and reaches an ejection track block (U block) 60 through this. Although this part is clearly shown in FIG. 4, since the track is U-shaped, all parts C are supplied to the upstream end of the linear vibrating feeder 34 with the longitudinal direction facing the transport direction. The discharge track block 60 is a linear vibration feeder 3
Since it is disposed just above the upstream end of 4, it is reliably supplied to the linear vibration feeder 34. Conventionally, this part is transferred between the discharge end of the vibrating parts feeder 33 and the upstream end of the trough of the linear vibrating feeder with a smaller gap than this part. Since such a small gap is not required, the component C is stably supplied on this track despite the minuteness.

A similar high-frequency drive current is applied to the electromagnet 45 of the linear vibration feeder 34, and the component C supplied to the upstream end thereof is transferred to the right in FIGS. 2 and 3. The part C which overflows also on the flat portion 61a of the first trough block 61 shown in FIG. 6 is transferred, and is moved to the left in FIG. 5 by vibration. Part C introduced into the first U track 61b and the second U track 61c
Is a single row with the longitudinal direction facing the transport direction and stably to the right (Fig. 2
5), but as shown in FIG. 5, a second U-track 61c having a downstream starting point.
The part C overflowed with the flat portion 61a is also introduced here and is similarly transferred by vibration. At the downstream portion in the second U-track portion 61c, they are merged and transported at a high density, and are introduced into the U-shaped groove 70a in the second trough block 70. This is transferred by vibration. As shown in FIG. 10, the starting point of the U-shaped groove 70 a starts from the upstream end and gradually deepens in the transfer direction, and the valley bottom line 70 abe becomes U-shaped. It is introduced into the V-groove 70ab formed so as to be directed toward the center line c of the groove 70a, but as shown in FIG.
0abc and a long side wall 70abd, where the part C is a valley bottom line 70ab of the U-shaped groove 70a.
e along the short side wall 70ab
and slides down along the short side c and is transferred to the short side wall 70abc by vibration. As described above, the V-groove 70ab is cut so as to go toward the center line c, so that the short side wall 70abc gradually becomes longer toward the center line c toward the downstream side as shown in FIG. As a result, as shown in FIG. 12, the bottom line 70ab of the V-groove 70ab is finally aligned with the center line c of the downstream next block. That is, as shown by an alternate long and short dash line in FIG. 12, the posture is sequentially changed by changing the length of the short side wall 70abc, and the discharge end is formed by the downstream block 72, the passage forming plate 73, the detection passage forming block 74, and the like. Into the second V-shaped groove. The upstream end has an open angle of 90 ° as clearly shown in FIGS. 10 and 12, but is guided stably to the downstream V-groove with a step.

As shown in FIG. 17, the V-groove 80a has an opening angle of 90 °, but the part C is transferred along the left side wall. Eventually, when reaching the intermediate portion of the passage forming block 74, as shown in FIG. 18, the upper surface of the block 74 is a narrow path 80b for transferring the parts. The component C is dropped on the track portion of the vibrating parts feeder 33 through the notch 74c.
Further, the components introduced here overlapped with each other are air ejection holes 73b.
Since the air is always blown out from the, the overlapping parts are also dropped into the notch 74c. Therefore, on the downstream side, the single-row, single-layer track 80c is supplied to the obtuse angle V track. Here, the movement of the component C ejected from each position of the air ejection hole, which is subjected to the operation according to the present invention, will be described with reference to FIGS.

As shown in FIG. 27, the air ejection holes 73a (7
If 3b) is in the direction toward the center of gravity G of the component C, the component C facing the back will fly along the parabola A and land on the other side wall 74 as shown in the b position, where the coefficient of friction is small. It is considered that the movement is different from that in the case of a great situation. In other words, when the coefficient of friction is small, the vehicle slides upward (to the right) from the state of the b position in the same position, and the kinetic energy of the component C decreases due to the sliding, so that the contact point P as shown in the c position. , And remains face-down. However, when the jetting power of the air is sufficiently large and the friction coefficient of the other side wall 74 is large, the part C is rotated clockwise around the contact point P from the state of landing in the b-position to the other ridge line adjacent thereto. Is further rotated with the contact point as a contact point, and the table (carbon film R) is oriented upward. Next, the other side wall can be slid downward (to the left) in FIG. 27 to have a desired front side. That is, in this case, the air jet output from the air jet small holes 73a (73b) is sufficiently large, and the frictional force between the other side wall surface and the component C is sufficiently small. In such a case, the length of the other side wall must be sufficiently long, unlike the conventional case.

Next, as shown in FIG. 28, when air is ejected from the air ejection holes 73a (73b) upward from the center of gravity G of the component C, the rotation around the center of gravity G and the translational movement The movement indicated by the flight line A is performed, and in this case, the center of gravity G
, And further lands at the contact point P, and then rotates around the contact point to take a posture shown by c. That is,
The other side is transferred with the face up.

Next, as shown in FIG. 29, when air is blown downward by the center of gravity G of the part C, the rotation and the translational movement around the center of gravity G are also performed. The part lands on the side wall surface to which the part has been transferred in the posture shown by. As a result, it can be turned face up on the same side wall and supplied to the next process, but it is not preferable because it may overlap with a subsequent component. The above description is for the case where the opening angle of the V-groove is an obtuse angle.
° is often used. In such a case, the movement of the part C as in the present embodiment will be described.

First, if an air jet output is applied so as to form the center of gravity G, the component C slides along the other side wall surface as indicated by the arrow B, and then slides in the opposite direction D. Therefore, the front and back of the component C cannot be changed.

Next, as shown in FIG. 31, when the air jetting power is given above the center of gravity G, it is also rotated around the center of gravity G. Upon contact with the side wall, receiving this drag, the amount of rotation is small and lands in the position shown by b, slides along the other side wall in the position shown below by c, and comes into contact with one side wall again. . Therefore, the front and back cannot be changed. As shown in FIG. 32, when air is ejected so as to be below the center of gravity G, this turning power also acts as a moment, but it flies along the trajectory A and becomes a state shown by b, and then the one side wall It makes contact and turns around this contact point as a fulcrum to take a posture indicated by c. That is, it is turned face up. However, it is not preferable because it may overlap with a component described later. As described above, when the opening angle is 90 °, it is difficult to reverse the angle.

The principle operation of the component reversing mechanism of the present invention has been described with reference to FIGS. 27 to 32. However, in an actual apparatus, the conditions are as shown in FIGS. That is,
In FIG. 33, a part of the block 74 and a part of the block 73 are shown in an enlarged manner, respectively, but the part C has a relation as shown in the drawing. At the lower end of the block 74 is a very small, in this embodiment 0.03 mm, vertical wall j. The component C is in contact with this by the action of gravity, and in FIG. 33, the component C is not hooked on the air ejection hole 73a. That is, the air ejection holes 73a
Even if air is blown from the part C, the part C is transferred to the downstream side by vibration without receiving this spray output. It must be inverted to the other side wall. In this case, air is ejected from the air ejection hole 73a, and the ejection power is directed above the center of gravity G in the component C as described above in principle with reference to FIGS.

That is, in FIG. 33, the block 74 can be slid rightward along one of the side walls of the block 73 by loosening the screws as described above. However, as shown in FIG. The block 74 is slid so as to partially overlap the air ejection hole 73a. In this case, the air ejection port is directed above or to the left of the center of gravity G. At first, it was detected that the posture was a face-down, and it flies along the parabola A by the air jet power, and lands on the other side M of the block 74 by the clockwise rotation and the translational movement around the center of gravity G. The center of gravity G rotates clockwise around the contact point P to take a posture c. That is, it is turned to the other side wall M. Next, as shown in FIG. 35A, the diameter of the air ejection hole 73a is 0.3 mm.
Since the width of the part C is 0.3 mm, the shape almost coincides (it is 0.6 mm in the longitudinal direction, so it does not fit into the air ejection hole 73a). Air is ejected from the hole 73a. The part C flies vigorously along the parabola A and lands on the other side wall M in the posture of b. When the friction coefficient of the other side wall M is small, it slides to the right like the posture of c (at this time, the kinetic energy decreases due to the sliding, and the center of gravity G rotates counterclockwise around the contact point P). 35d. If the friction of the other side wall M is large, as shown in FIG. 35B, the aircraft flies from the position of a and lands in the position of b. Without contact, the center of gravity G is the contact point P
And then rotate to take the position of d with the kinetic energy of rotation, and then slide the other side wall M to the other side as shown by e to face up, and the part C along the other side wall M Is transported. From this fact, if the distance from the boundary (valley bottom line) between the other side wall M and one side wall L to the center axis of the air ejection hole 73a is between FIG. 34 and FIG. Can be. Further, according to the present embodiment, as shown in FIGS. 33 to 35, the size of the air ejection hole 73a is formed to be approximately equal to the diameter of the small component C of 0.3 mm in width, so that Processing can be facilitated. Conventionally, of course, the diameter of the air ejection hole is much smaller than the width of the component. As shown in FIGS. 33 to 35, a very small vertical portion of 0.03 mm is provided at the lower end of the other side wall M. However, this is provided because sharp edges are dangerous to handle. In fact, it is clear that a similar effect can be obtained even with a sharp edge without a minute vertical wall portion j as shown in FIG.
