BACKGROUND OF THE INVENTION
The present invention relates to a component attitude selection device.
[0002]
[Prior art]
FIG. 1 shows a minute electronic component m, which is a rectangular shape having a very small length of 0.6 mm, a short side of 0.3 mm, and a height of 0.25 mm. This a-plane requires a black print portion having a lower light reflectivity than the other surfaces. There is a case where such a small part is desired to be transferred in a direction indicated by an arrow A. For example, it is transferred by a vibration part feeder, but in the posture shown in FIG. 1B, the b-plane is upward and the a-plane is downward. That is, the surface with a low light reflectivity is set downward. Parts having such a posture are excluded from the vibration track, assuming that they are in a different posture. Next, the component shown in FIG. 1C, that is, the component with the black surface and the a-faced posture is also determined to be in a different posture and is excluded to the outside of the vibration track. Next, as shown in FIG. D, when the a-plane is on the left side in the transfer direction, it is determined that the posture is different. I would like to supply only the component shown by the posture in FIG. 1A to the next process as a correct posture, but detect whether such a minute component m is in a different posture or a normal posture and supply only the correct posture to the next step. It is also conceivable to eliminate the other parts in the postures B, C, and D, or correct them to the normal posture shown in FIG. 1A. However, it is very difficult to correct the posture of such a minute part m. Further, the supply efficiency of the components with the normal posture supplied to the next process is greatly reduced only by removing the components with different postures outward.
[0003]

The Downstream Due to the slope of the first transfer road surface The second part attitude detection device joins the parts being transported on the vibration track, and different attitudes The parts detected as Activating the second air blowing device The parts having different postures are blown off from the vibration track to the second transfer path surface on the second side wall portion side, and on the second transfer path surface on the second side wall portion side. The parts are transferred to the downstream side by vibration. And by the inclination of the second transfer path surface on the downstream side Transferred on the vibrating track ing The problem is solved by a component orientation selection device characterized in that it is merged with a component.
[0005]
Alternatively, a part is transferred in a predetermined direction along a vibrating track, and a part posture detection unit is provided on the track, and a part that is not in a predetermined posture is excluded outward by the air blowing unit by the part posture detection unit. In the component orientation sorting apparatus, the truck is moved with respect to the component transfer direction. One side direction Inclined downward to move the parts while abutting against the side wall of the track, The component attitude detecting means and the air ejecting means are each composed of at least a first and second component attitude detecting device and an air ejecting device along the track, respectively, and the track close to the first component attitude detecting device is A first transfer path surface having one side end portion with respect to the transfer direction of the component and inclined downward toward the side end portion side including the side end portion; and the first transfer path surface A first side wall provided to rise from the side of the first transfer path at a side end opposite to the one side end, and the second side on the downstream side of the first transfer path.

It is solved by the attitude sorting device.
[0006]
With the configuration as described above, even a minute part as shown in FIG. 1 can efficiently supply a normal part.
[0007]
Small parts, especially vertical, horizontal, and height parts of 1 mm or less are connected to a vibration feeder, for example, a connection between a vibration part feeder that twists and vibrates a ball and a linear feeder that linearly vibrates a linear trough, or vibration. Troubles (eg, gaps, stepping, etc. at gaps) between the feeder and some parts supply means often occur (for example, drops in the gaps, changes in posture, etc.). Become more. Therefore, the conventional method of detecting the normal posture and the different posture of the parts and removing all the different postures in the bowl and transferring only the normal posture parts to the downstream side as they are cannot make the transfer speed of the parts too high. Therefore, the supply efficiency of the next process becomes low. However, according to the present invention, even if the transfer speed is lowered to a level that does not cause a trouble at the connection to the next process, the supply efficiency of the components in the normal posture can be increased more greatly than in the past.
[0008]

In the figure, the first and second component attitude detection devices 3A and 3B and the first and second components are detected. 3C, a component attitude detection device 3C for returning 3D The bowl 2 provided with the base block 4 is coupled to the lower base block 4 by a laminated leaf spring 6 disposed at equiangular intervals, and an electromagnet 5 around which an electromagnetic coil is wound is attached on the base block 4. Yes The armature 8 is fixed to the bottom of the bowl 2 with a gap therebetween. The entire torsional vibration drive unit is covered with a cylindrical cover 7, and the entire vibration parts feeder 1 is supported on the ground by vibration-proof rubber 9.
[0009]
As shown in FIG. 3, it is assumed that a large amount of minute parts m as shown in FIG. A vibration track 10 that rises in a spiral shape from the center bottom 2a is formed, and a notch 11 having a three-month shape is formed in the middle. And led to the downstream side. Reference numeral 12 denotes a quick-release mechanism. When a part is desired to be replaced, the part is quickly removed outward by rotating the part. Further, a substantially U-shaped groove 13 is formed on the downstream side of the bowl 2, where the component is corrected by vibration so as to face the longitudinal direction thereof and guided to the downstream side.
[0010]
4 and 5 show the details of the above-mentioned quick-release mechanism 12, but a block 22 having a cross-sectional shape as shown in the figure is fixed to a part of the bowl 2, and a part 23a is notched as shown in FIG. Both the disk-shaped blocks 23 are fixed to the bowl 2. A shaft portion of a bolt 25 is inserted into the block 22, and the tip screw portion is screwed and fixed in a screw hole of the block 23, and is further securely fixed by a set screw 24. An operation rod 21 is attached to the knob portion 20, and a winding spring 26 is wound between the knob portion 20 and the block 22.
[0011]
FIG. 6 is an enlarged cross-sectional view in the [6]-[6] line direction in FIG. 3, but the blocks 31 and 32 are fixed to the bowl 2 continuously to the U-shaped groove 13 described above, and these inclined surfaces 31a. , 32a form a track T for guiding it into the first and second component orientation sorting devices 3A, 3B according to the present invention.
[0012]
7 is a cross-sectional view in the [7]-[7] line direction in FIG. 3, the block 32 described above is formed with an inclined surface 32 b (notch) that is inclined downward inward of the bowl 2. In addition, an air ejection block 31 is fixed to the block 32, and air is constantly ejected from a hole 34 formed in the block 31 through an air ejection pipe 33. The height of the hole 34 is larger than the height of the component m, and smaller than twice the height.
[0013]
FIG. 8 is an enlarged cross-sectional view in the [8]-[8] line direction in FIG. 3 and shows the entire first component posture detection device 3A. In the drawing, the downstream portion of the above-described block 32 is fixed to the bowl 2 as a transfer path forming block, and a posture detection block 42 is further fixed thereto, and an attachment for fixing the posture detection tube 47 is fixed thereto. The member 46 is fixed. The block 32 is formed with a transfer path surface 32a which is inclined leftward and downward in the figure, and the left end portion thereof forms a vibration track T. A through hole 49 is further formed in the block 32 in the vertical direction, and an air jet pipe 48 is screwed and fixed to a screw hole g formed in the peripheral wall portion of the bowl 2. A gap with a triangular cross section between the blocks 32 and 42 50 However, a small gap S is formed between the blocks 32 and 42 in the portion corresponding to the apex. This height is smaller than the height of the component m (see FIG. 9).
[0014]
According to the embodiment of the present invention, as shown in FIG. 9, the optical fiber for detecting the component posture includes one optical fiber 50 at the center and eight optical fibers 51 arranged around the optical fiber. These are bundled and stored in the metal tube 47. As is well known, a light emitting element is attached to the end of the light projecting fiber 50, and the eight optical fiber strands 51 are bundled and a light receiving element is attached to the end.
[0015]
The light projecting optical fiber in the center has a diameter of 0.25 mm, and the light receiving optical fiber disposed around the center has a diameter of 0.125 mm. And the diameter of the metal tube 47 which bundles and accommodates this is 0.8 mm. As shown in FIG. 9, the posture of the component m is detected when it passes the front, but if it is determined to be in a different posture, air is ejected from the gap S and removed laterally from the vibration track portion T. Like to do.
[0016]
As clearly shown in FIG. 10, the side wall 32c is formed on the radially inner side of the bowl 2 on the transfer path surface 32a. Arc-shaped notches 41a and 41b are formed on both sides of the side wall 32c. The transfer path surface 32a disappears, and only the vibration track T is formed, and a transfer path surface 32a that is inclined downward toward the vibration track T in a range including the side wall portion 32c is formed. Therefore, even if air is blown out from the gap S and the part m is blown off to the side, it is prevented from being blown into the bowl 2 by the side wall 32c.
[0017]
FIG. 11 is an enlarged cross-sectional view in the [11]-[11] line direction in FIG. 3. The block 32 and the block 31 are fixed to the bowl 2, but the inner surface of the block 31 is clearly shown in FIG. The part m, which is arcuate, is transferred by vibration in the direction of arrow B as clearly shown in FIG. 10 along this inner surface due to the downward inclination of the transfer path surface 32a toward the outer diameter of the bowl 2. Further, as shown in FIG. 10, there is a region where the side wall portion 32c does not exist. However, as shown in FIG. 12, the width of the transfer path surface 32a is narrowed by the notch 41b so as to be slightly larger than the width of the part. T. It passes through the narrow vibration track T shown in FIG. 12 and reaches the second component posture detection device 3B, but the configuration is completely the same as that of the first component posture detection device 3A on the upstream side, and the description thereof will be omitted.
[0018]
On the further downstream side of the vibration track T, a first component return detection device 3C and a second return device posture detection device 3D are provided. Since these are also the same as the first and second component attitude detection devices 3A and 3B, the description thereof will be omitted. However, in the vibration track portion T, the transfer road surface is inclined downward toward the vibration track portion T as described above. 32a does not exist and remains in a narrow path. Therefore, when air is ejected from the air ejection device, it is blown away inward of the bowl 2. Thus, from the tunnel-shaped outlet 14, only parts having a correct posture, that is, components having a posture as shown in FIG. 1A are supplied to the next process.
[0019]
Although the embodiment of the present invention has been described above, this operation will be described next.
[0020]
As shown in FIG. 2, when an alternating current is applied to the coil of the electromagnet 5, the armature 8 is attracted, and the bowl 2 is torsionally vibrated about its central axis by the torsional bending of the overlap spring 6 as is well known.
[0021]
Although not shown, a large amount of the component m is stored in the central bottom portion 2a of the bowl 2, but the component m is made into a single row along the track 10 and transferred downstream. When the component m is introduced into the U groove 13 on the downstream side, it is transferred in a substantially single row with the action of vibrations in the longitudinal direction in the transfer direction, and enters a sorting portion formed as an attachment from here as shown in FIG. . First, the groove 13 is introduced into a valley bottom formed by slopes 31 a and 32 a as vibration tracks formed by the blocks 31 and 32, and the track T formed in the V shape is used as a boundary line between the blocks 31 and 32. Along with the vibrations.
[0022]
As shown in FIG. 7, the transfer path 32 a is narrowed by a notch 32 b, and the narrow path portion constantly blows air from the air jet pipe 33, so that all the parts m overlapped here are of the bowl 2. Eliminated inward.
[0023]
Therefore, it is introduced into the first component attitude detection device 3A in a single layer. As shown in FIG. 9 mounted in the metal pipe 47, the optical fiber strand 50 projects light onto the currently facing surface of the component m, which now reflects light as shown in FIG. 1A. If the surface a is small, this is the correct posture, so that it is transferred to the downstream side by vibration without blowing air. Further, when the component m passing therethrough passes in the posture as shown in FIGS. 1B, 1C, 1D, the surface thereof has a high light reflectivity, so that it is connected to the end of the optical fiber 51. When the light receiving level of the light receiving element is increased, it is determined that this is a component with a different posture, and the component m is blown off to the side by air.
[0024]
As shown in FIG. 10, the parts m in different postures are blown off on the inclined transfer road surface 32a, and guided to the lower vibration trough part T while being transferred by vibrations. Interrupt. Although the posture settled on the transfer road surface 32a is still a different posture or a correct posture by blowing off by air jet, the proportion of the normal posture of the component m increases. Accordingly, in the downstream side of the vibration track portion T, the correct component m is increasing.
[0025]
As shown in FIG. 11, it passes through the region where the side wall 32c shown in FIG.
[0026]
As shown in FIG. 3, the row of components m is introduced into the second component orientation detection device 3B and is subjected to the same action as the first component orientation detection device 3A. Accordingly, in the row of components m guided downstream through the second component orientation detection device 3B, the proportion of the components m in the correct orientation is increased.
[0027]
Next, when the first return component posture detection device 3C is reached, the posture of the component is detected in the same manner as the first and second component posture detection devices 3A and 3B. If the posture is different, air from the gap s is detected. By the ejection, all is removed toward the center bottom 2a of the bowl 2. Similarly, the second return component posture detection device 3D performs the same operation, and as a result, only the component m having the correct posture is reliably supplied to the next process from the tunnel-shaped discharge port.
[0028]
According to the embodiment of the present invention, component posture detection is performed by the optical fiber strand 50 as shown in FIG. 9, and the correct posture is determined from the light receiving level of the light receiving element connected to the optical fiber strand 51. Whether the posture is incorrect or not is determined, but the optical fiber strands 50 and 51 are very thin as described above, and the diameter of the metal tube 46 into which these are fitted together is as small as 0.8 mm.
[0029]
Thereby, as described above, it is very small, that is, the long side, the short side, and the thickness can be as close as possible to the minute component m of 1 mm or less. According to the conventional optical fiber attitude detection, the diameter of the metal tube with a large number of fibers was so large that it could not be made very close, so even if the light reflection level was measured, the noise was large and accurate. Although there was a case where it was impossible to measure, the component attitude detection device of the present invention can detect the attitude of a very small component m as close as possible without noise.
[0030]
In addition, as described above, in combination with the second component posture detection device 3B, the proportion of components in the correct posture can be increased and led to the downstream side, so that the component m is supplied to the next process with higher supply efficiency than before. I can do it.
[0031]
When replacing the components in the bowl 2, the notch 23a of the disk block 23 is moved to the bowl by rotating the lever 21 clockwise or counterclockwise in the quick-release mechanism 12 shown in detail in FIGS. 2 so that all parts m flowing from the upstream side fall on the discharge plate 27 through the notches 23a and are connected to the discharge chute connected to the discharge chute (not shown). Lead. Therefore, the part in the bowl 2 can be quickly replaced with the next part. Further, according to the quick-release mechanism 12, it is possible to quickly advance parts by simply rotating the lever 21 with a finger without using any tools. In the above embodiment, the threaded portion G is formed in the metal tube 47 in which the optical fiber elements 50 and 51 are housed, and this is screwed to the block 46. The front end portion of the vibration track T can be adjusted in the front-rear direction by rotating clockwise or counterclockwise. Therefore, the posture can be adjusted according to the shape and size of the component to be detected. In addition, the most sensitive point can be selected by this adjustment.
[0032]
Further, in the above embodiment, a rectangular part is described as a minute part as shown in FIG. 1, but its c-plane is very close to 0.3 mm and 0.25 mm in length and width, that is, close to a square. . In addition, the longitudinal direction, ie, the long side of 0.6 mm is about twice as long as that. Therefore, such a component m is transported on the vibration track T described above, and is transported when the component m having a different posture is blown off on the inclined transport surface by the jet air. It is transferred by vibration along the surface, but the transfer surface is easy to roll with the roller on the way, so the probability of the normal posture is increased, and there are many parts that are in the normal posture on the downstream side. Increase the proportion of parts in the correct posture. Now, if the part is flat and the height is low, such a probability will be small.
[0033]
The embodiment of the present invention has been described above. Of course, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.
[0034]
For example, in the above-described embodiment, the vibration parts feeder 1 including the circular bowl 2 has been described as the vibration feeder. However, the present invention is not limited to this, and linear vibration is converted into a linear trough. You may apply to the linear vibration feeder which gives and transfers components. As shown in FIG. 13, one linear vibration feeder 70 is provided with devices 74A and 74B that are equivalent to the first and second component attitude detection devices 3A and 3B described above, and close to the vibration track 72 in a downward direction. Inclined transfer road surfaces 80A and 80B are provided to perform the same operation as described above. On the downstream side, devices 75A and 75B equivalent to the first and second component posture detection devices 3C and 3D for return described above are provided. Accordingly, the component m having a different posture is dropped onto the inner track portion 70b which is lowered to a lower level, and is moved to the left so that the trough of the other adjacent linear vibration feeder 71 Into the linear vibration feeder 70 described above. The present invention can also be applied to such a linear vibration feeder.
[0035]
In the above embodiment, the first and second component attitude detection devices 3A and 3B are provided. However, the number is further increased, and the same third, fourth,... May be. In addition, the proportion of parts in the correct posture can be increased. The same applies to the return component posture detection device on the downstream side.
[0036]
Further, in the embodiments of the invention described above, a rectangular part having a long side, a short side, and a height of 1 mm or less has been described. Of course, it is not necessary to use a part having such a dimension. It can also be applied to shaped parts. Further, in the above embodiment, as the different postures of the parts, the front and back are selected as the so-called postures of parts having a rectangular shape as shown in FIG. 1 and the light reflection intensity of one surface being smaller than the other surfaces. Of course, the front and back surfaces are not selected, and the reflection intensity is the same on both surfaces, but the reflection intensity varies depending on the posture of the component when passing through the component posture detection device. For example, a part with a part receives light partially and does not receive part of the light from the optical fiber element so that only such a part has a correct posture and is supplied to the downstream side. You may make it exclude to a side as a different attitude | position by all reflecting intensity becoming large.
[0037]
In addition, the above-mentioned minute parts have a rectangular shape, but of course, the shape is not limited to this shape. For example, the different postures of the cylindrical and rectangular tube parts are detected by the component posture detection device as described in the embodiment. All are applicable if possible. In the above embodiment, an optical fiber is used as the component posture detection device. However, instead of this, all conventionally known component posture detection devices can be applied. For example, a small through hole like a needle hole is provided for a micro component, and the posture is determined by whether or not this light is blocked by a light receiving element disposed opposite to the light beam from the light receiving element. May be. Further, in the above embodiment, the transfer road surface inclined downward toward the vibration track T is provided to be connected to the vibration track independently with respect to the first and second component attitude detection devices 3A and 3B. However, instead of this, they may be formed as one inclined road surface without being narrowed between them. The present invention includes both cases as the “transfer road surface”. In the above embodiment, the first and second return component posture detection devices 3C and 3D are provided, but these can be omitted. For example, it can be omitted if the transfer speed due to vibration of the component is low and depending on the shape of the component, the change of the component from the different posture to the normal posture can be reliably performed in two or three times.
[0038]
Moreover, in the above embodiment, the inclination angle of the inclined transfer path surface 32a is constant, but this angle may be adjustable. As a result, it is possible to optimize the proportion of the correct postures of the components introduced experimentally into the first and second component posture detection apparatuses.
[0039]
In the above embodiment, as shown in FIG. 8, the combination of the blocks 32 and 42 is used to form a slit-like air outlet s between them. May be formed. However, according to the present embodiment, the small holes s can be formed much more easily and accurately by the combination of the blocks 32 and 42. In addition, although the optical fiber elements 50 and 51 are arranged as shown in the figure as a posture detection member, a conventional detection member in which a multilayer fiber element is bundled can be applied depending on the size of the parts. It is. Further, as shown in FIG. 9, the number of light detecting members may not be eight for receiving light, but a light detecting member made up of one optical fiber element 50 and two light receiving fiber elements is also applicable depending on the shape of the component. Similar to the embodiment, it is possible to determine the posture accurately even though it is a minute component by bringing it closer to a minute component and reducing noise.
[0040]
【The invention's effect】
As described above, according to the component orientation selection apparatus of the present invention, even with a minute part having a long side, a short side, and a height of 1 mm or less, the component can be efficiently supplied to the next process in the correct posture. I can do it.
