Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component front / back aligning device in a vibrating component feeder for aligning and transporting a large number of components such as chip-shaped electronic components in a single-row single layer while vibrating them and supplying them to external equipment.

[0002]

2. Description of the Related Art For example, a vibrating component feeder (part feeder) for vibrating a large number of rectangular small electronic components such as small chip resistors and chip diodes to align and convey them in a single row and single layer.
Is very useful for automatically mounting electronic components on printed circuit boards. In some electronic components that are automatically mounted on a printed circuit board, the back surface directly mounted on the printed circuit board and the surface on the opposite side must be selected and supplied to the printed circuit board. A vibrating component feeder that supplies such electronic components to a printed circuit board has a function of discriminating between the front and the back of electronic components conveyed in a single-row single layer, and aligning the front and the rear.

Generally, a vibrating component feeder comprises a bowl-like bowl and a vibrating mechanism for supporting and vibrating the bowl.
A large number of parts randomly supplied into the bowl transfer to the alignment path from the lower end inlet of the alignment path formed in a spiral shape on the inner peripheral surface of the bowl by vibrating from the bowl. The parts transferred to the alignment path are conveyed toward the upper end exit of the alignment path while being subjected to vibration, the arrangement is corrected to a single-row single layer while being conveyed, and the front and back sides are aligned in the required direction. To be

A reflection type optical sensor is generally used as a front / back discriminating means for a component having front and rear surfaces. That is, in many of the rectangular chip-shaped parts such as electronic parts, the back surface is a specular surface with good light reflectivity mainly composed of resistors mounted on a printed circuit board, and the surface is a non-mirror surface with poor light reflectivity. Since it is a surface of the vibrating component, the light of the optical sensor is applied to the upper surface of the component aligned in a single row and a single layer in the alignment path of the vibrating component supplier, and the presence or amount of the reflected light is detected by the optical sensor. If you do
It is possible to determine whether the top surface or the back surface of the component conveyed on the alignment path is the front surface or the back surface.

After determining the front and back surfaces of such a part,
As the parts front and back side aligning means for aligning the top surface of the parts to either the front side or the back side, a means using a groove or a step provided in the width of the parts in the alignment path, or an alignment path having a V-shaped cross section is used. The means are known. In the former, the parts are conveyed by rolling them sideways (sideways) on a groove or step provided along the alignment path that conveys the parts with either the front side or the back side facing up, and based on the signal that distinguishes the front and back sides of this part. , The wiper or compressed air is blown, and the overturned parts are tilted in a desired direction to align the front and back of the parts on the alignment path.
The latter conveys the component along one of a pair of inclined surfaces facing the V-shape of the V-shaped cross-section alignment path, and the front and back of the component are in a desired orientation based on a signal that distinguishes the front and back of the component. If it is, the part is conveyed along one inclined surface as it is, and if the front and back of the part are in the opposite direction, blow compressed air to the part and reverse move to the other inclined surface. By doing so, the front and back of the parts are aligned.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The parts front and back aligning device utilizing the grooves and steps of the alignment path described above has a problem that parts are clogged between the alignment path and the wiper or in the grooves of the alignment path, and the alignment path structure is complicated. There was a problem that is difficult.

The above-mentioned component front and back aligning device utilizing the V-shaped cross section has a simple alignment path structure, and there is no concern that the parts will be clogged in the alignment path. However, the parts have a pair of inclined surfaces facing each other in the V shape. Since it is aligned on both sides, it is necessary to provide a special merging passage downstream of the arranging passage for merging the components conveyed from both inclined surfaces into a single row. Therefore, the device structure becomes complicated. Further, when the component is reversed and moved to the other inclined surface, the compressed air is momentarily ejected to press the component, so that the component strongly hits the other inclined surface and re-inverts to the one inclined surface. There are also concerns.

Further, in any of the above devices,
When changing the orientation of the front and back alignment of parts (for example, when changing from front alignment to back alignment), replace the block of the alignment path with another block having an optical reflectance,
A complicated operation such as switching the mode of the reflection type optical sensor is required.

Therefore, the object of the present invention is to
It is an object of the present invention to provide a parts front and back aligning device in which clogging of parts is unlikely to occur, front and back of the parts are surely aligned, the front and back directions of the parts can be easily changed, and the structure is relatively simple.

According to the first aspect of the invention, the parts front and back aligning device aligns the parts on the first inclined surface in a desired front and back direction. That is, a component is introduced along a first inclined surface of an alignment path having a V-shaped cross section composed of a first inclined surface and a second inclined surface facing each other in a V shape, and if the upper surface of this component is in a desired direction, for example, a back surface. ,
Pass the parts as they are along the first inclined surface,
If it is in the opposite direction, for example the surface, the pressing means is actuated to slide the component from the first inclined surface to the second inclined surface with the surface facing upward. Then, after that, the first reversing unit reversely moves the component, which has been slid on the second inclined surface, on the first inclined surface. The inverted component is on the first inclined surface and the top surface is the back surface. Therefore, all the parts that have been discriminated from the front and back are aligned front and back on the first inclined surface with the back side facing up.

According to another aspect of the present invention, there is provided a component front / back surface aligning device for aligning components on a second inclined surface in a desired front / back direction. That is, the component is introduced along the first inclined surface of the alignment path having the V-shaped cross section, which is formed by the first inclined surface and the second inclined surface facing each other in the V shape, and the upper surface of the component is in a desired orientation, for example, the surface. , The pressing means is operated to slide the component from the first inclined surface to the second inclined surface while keeping the surface upward. Parts that have been slid sideways are transported downstream as they are. If the upper surface of the component is in the opposite direction to the desired orientation, for example, the rear surface, the second reversing unit reversely moves the component on the first inclined surface onto the second inclined surface.

Embodiments of the present invention will be described below with reference to the drawings.

1A to 1C are a partial plan view and a sectional view of an alignment path 1 formed in a bowl of a vibrating component feeder, and the alignment path 1 has, for example, a rectangular chip-shaped component. 2 receives vibration and is conveyed. The alignment path 1 is a groove having a V-shaped cross section, and includes a first inclined surface 1a and a second inclined surface 1b facing each other in the V shape. First inclined surface 1a and second inclined surface 1b
Tilts at an angle of approximately 45 °. The component 2 is the first inclined surface 1
It is guided into the alignment path 1 in a state of falling to the a side.

The component 2 has a specified front surface m and back surface n. For example, the back surface m is shown by diagonal lines in the drawing, and this surface is mainly a resistor mounted on a printed circuit board or the like and has good light reflectivity. And the opposite surface n is a non-specular surface having poor light reflectivity. In the component 2, the rear surface m or the front surface n is in contact with the first inclined surface 1a of the alignment path 1 and the end surface of one side is in contact with the second inclined surface 1b.
It is conveyed in the direction of the arrow in (a).

In this embodiment (first embodiment), a reflective optical sensor 5 as front and back discriminating means and an air hole 3 as pressing means are provided at a first position P1 in the middle of the alignment path 1.
Also, the reversing prevention claw 6 is installed, and the air hole 4 as the first reversing means is installed at the second position P2 downstream of the first position P1. The first inclined surface 1a of the alignment path 1 is aligned in the direction (for example, the back surface m).

The optical sensor 5 at the first position P1 is installed at a fixed position facing the first inclined surface 1a at a predetermined interval, and the air hole 3 is formed at the lower end of the first inclined surface 1a.
The inversion prevention claw 6 is provided on the first inclined surface 1 from above the second inclined surface 1b.
It is extended and fixed at a fixed position in the sky above a. The air hole 4 at the second position P2 is provided on the side of the second inclined surface 1b.
It is formed in the middle of the width of the component 2 from the lower end of the inclined surface 1b.

The first inclined surface 1a is introduced into the alignment path 1.
When the component 2 conveyed along the line reaches the first position P1, the detection light is emitted from the optical sensor 5 toward the inclined upper surface of the component 2, and the optical sensor 5 detects the presence and amount of the reflected light. Then, it is determined whether the upper surface of the component 2 is the back surface m or the front surface n.

For example, as shown in FIG. 2, the upper surface of the component 2 which has reached the first position P1 is a back surface m having good light reflectivity.
Then, the compressed air in the air hole 3 is maintained in a non-operating state. In this case, the component 2 is continuously conveyed along the first inclined surface 1a, passes through the second position P2 as it is, and is conveyed downstream.

On the contrary, as shown in FIG. 3 (a), when the upper surface of the component 2 reaching the first position P1 is the surface n having poor light reflectivity, the optical sensor 5 detects this and the air is detected. The holes 3 are opened, and compressed air is ejected from the air holes 3 for a short time. Then, as shown in FIG. 3B, the compressed air ejected from the air hole 3 momentarily presses the inclined lower end portion of the component 2 at the first position P1 to move the component 2 upward from the upper surface (surface n). The second slanted surface 1b while sliding toward the side
Move to. At this time, the inversion prevention claw 6 acts so that the upper end of the component 2 of the first inclined surface 1a does not rotate and move to the second inclined surface 1b side, and prevents the front and back of the component 2 from being inverted. The side slide movement of the component 2 to the second inclined surface 1b is ensured. Further, the reversal prevention claw 6 prevents the vertical and horizontal postures of the component 2 from changing during lateral sliding movement. Therefore, even if the component 2 is slidably moved by a strong pressing force, it is unlikely that the component 2 is inverted or the posture is changed vertically and horizontally, and the certainty at the time of high speed operation is high. The inversion prevention claw 6 may be formed of a translucent material so as not to interfere with the front / back detection by the optical sensor 5, or may be provided with a hole for allowing the detection light to pass therethrough.

As shown in FIG. 3B, the first inclined surface 1a
The upper surface of the component 2 slidingly moved to the second inclined surface 1b from is still the surface n. When this part 2 is conveyed a little along the second inclined surface 1b and reaches the second position P2, the state shown in FIG.
As shown in (a), it is pressed by the compressed air constantly ejected from the air hole 4. Then, Figure 4
As shown in (b), the upper end portion of the component 2 lying on the second inclined surface 1b is pressed by the compressed air from the air hole 4, and the component 2 moves from the upper end portion side to the first inclined surface 1a. The reverse movement is performed and the front and back of the component 2 are reversed. Since the component 2 is reversed by the compressed air constantly ejected from the air hole 4, re-reversal of the component 2 and change of the vertical and horizontal postures are unlikely to occur, and the reliability during high-speed operation is high. The component 2 that has been turned over from the second inclined surface 1b to the first inclined surface 1a has its back surface m, and the second surface is directly moved along the first inclined surface 1a.
It is conveyed downstream from the position P2.

Therefore, the second position P of the alignment path 1
The upper surfaces of all the components 2 on the downstream side of 2 are aligned with the back surface m, and all of them are aligned in a single-row single layer along the first inclined surface 1a. As a result, the part 2 exiting the alignment path 1
Since it is already in a single row, it is not necessary to additionally provide a merging passage for joining two rows into a single row as in the conventional case.

Embodiment shown in FIGS. 5 to 7 (second embodiment)
Is provided with a reflection type optical sensor 5 as a front and back discriminating means, an air hole 3 as a pressing means, and an inversion prevention claw 6 at a first position P1 in the middle of the alignment path 1, and a first position P1 downstream from the first position P1. An air hole 8 serving as a second reversing means is installed at the 2 position P2, and the component 2 is aligned in the desired front-back direction (for example, the front surface n), as described below.
Are aligned with the second inclined surface 1b. At the second position P2, except that the air hole 8 as the second reversing means is installed on the first inclined surface 1b side, and the air hole 4 as the first reversing means is not installed, other The configuration is the same as that of the first embodiment described above. The air hole 8 at the second position P2 is formed in the middle of the width of the component 2 from the lower end of the first inclined surface 1b.

The first inclined surface 1a is introduced into the alignment path 1.
When the component 2 conveyed along the line reaches the first position P1, the detection light is emitted from the optical sensor 5 toward the inclined upper surface of the component 2, and the optical sensor 5 detects the presence and amount of the reflected light. Then, it is determined whether the upper surface of the component 2 is the back surface m or the front surface n.

For example, if the upper surface of the component 2 which has reached the first position P1 is the back surface m having good light reflectivity, the compressed air in the air hole 3 is maintained in a non-operating state. in this case,
The component 2 is conveyed to the second position P2 along the first inclined surface 1a with the back surface m facing upward. When the component 2 reaches the second position P2, it is pressed by the compressed air constantly ejected from the air hole 8 as shown in FIG. 7 (a). Then, as shown in FIG. 7 (b), the upper end of the component 2 lying on the first inclined surface 1 a is pressed by the compressed air from the air hole 8,
The component 2 reversely moves from the upper end side to the second inclined surface 1b,
The front and back of the part 2 are reversed. Then, the component 2, which has been moved upside down from the first inclined surface 1a to the second inclined surface 1b, has the upper surface thereof as the surface n, and is conveyed as it is from the second position P2 to the downstream side along the second inclined surface 1b. .

On the contrary, as shown in FIG. 6 (a), when the upper surface of the component 2 reaching the first position P1 is the surface n having poor light reflectivity, the optical sensor 5 detects this and the air is detected. The holes 3 are opened, and compressed air is ejected from the air holes 3 for a short time. Then, as shown in FIG. 6B, the compressed air ejected from the air hole 3 momentarily presses the inclined lower end portion of the component 2 at the first position P1 to move the component 2 upward from the upper surface (front surface n). The second slanted surface 1b while sliding toward the side
Move to. The upper surface of the component 2 which has slid from the first inclined surface 1a to the second inclined surface 1b is the surface n,
It passes through the second position P2 as it is and is transported downstream.

Therefore, the second position P of the alignment path 1
The upper surfaces of all the components 2 on the downstream side of 2 are aligned with the front surface n, and all of them are aligned in the single row and single layer along the second inclined surface 1b. As a result, the part 2 exiting the alignment path 1
Since it is already in a single row, it is not necessary to additionally provide a merging passage for joining two rows into a single row as in the conventional case.

As is clear from the above description, at the first position P1 of this embodiment, the optical sensor 5 detects the front and back of the component 2, and the component 2 passes through as it is, or
The operation of sliding to the second inclined surface 1b is exactly the same as the operation (FIG. 3) at the first position P1 of the first embodiment described above. Therefore, between this embodiment and the first embodiment, it is possible to use the blocks having the same reflectance as the blocks of the alignment path 1 and to set the reflection type optical sensor 5 to the same mode setting. In the embodiment, the mode of the optical sensor 5 is matched with the reflectance of the surface n.)
Can be

In the embodiment (third embodiment) shown in FIG. 8, a reflective optical sensor 5 as front and back discriminating means and an air hole 3 as pressing means are provided at a first position P1 in the middle of the alignment path 1.
Further, the reversing prevention claw 6 is installed, and the air hole 4 as the first reversing means and the air hole 8 as the second reversing means are installed at the second position P2 downstream of the first position P1 to connect the air hole 4 and the air. By selectively switching between normally open and normally closed holes 8, the component 2 is aligned with either the first inclined surface 1a or the second inclined surface 1b in the required front-back direction. In the second position P2, both the air hole 4 as the first reversing means and the air hole 8 as the second reversing means are provided, and other configurations are the same as those in the first embodiment and the second embodiment. It is exactly the same as the embodiment. Therefore, in the second position P2, when the air hole 4 is normally opened and the air hole 8 is normally closed, the configuration is the same as that of the first embodiment, and the air hole 4 is normally closed and the air hole 8 is normally opened. Then, the same configuration as that of the second embodiment is obtained. In other words, it is possible to switch between the configuration of the first embodiment and the configuration of the second embodiment only by controlling the opening / closing of the air holes 4 and 8. By this switching, it is possible to easily change the front-back alignment direction of the components 2.

For example, when the components 2 are aligned with the back surface m facing upward, the air holes 4 are always opened and the air holes 8 are normally closed, and the components 2 are arranged in the manner as shown in FIGS.
Can be aligned front and back on the first inclined surface 1a with the back surface m facing up. Conversely, when the components 2 are aligned with the surface n facing up, the air holes 4 are always closed and the air holes 8 are always mounted. When opened, the component 2 can be aligned front to back on the second inclined surface 1b with the surface n facing up in the manner shown in FIGS. 6 and 7.

As described above, the configuration of this embodiment is the second
Only by controlling the opening / closing of the air hole 4 and the air hole 8 at the position P2, it is possible to easily change the front-back alignment direction of the component 2, and replace the block of the alignment path 1 with another block having an optically different reflectance. In addition, no complicated operation such as switching the mode of the reflective optical sensor 5 is required. Moreover, the upper surfaces of all the components 2 on the downstream side of the second position P2 of the alignment path 1 are aligned with the back surface m or the front surface n, and all of them are the first inclined surface 1a or the second inclined surface 1a.
Since they are arranged in a single-row single layer along the inclined surface 1b, it is not necessary to additionally provide a merging channel for joining two rows into a single row as in the conventional case.

The component 2 is in the first position P1.
The pressing means for sliding sideways and the first inverting means and the second inverting means for inverting the front and back of the component 2 at the second position P2 are not limited to compressed air, but may be mechanical means such as piston pins. However, it is desirable that the compressed air moves the component 2 safely without fail and the mechanical operation is easy.
