Description

[Detailed description of the invention] The present invention relates to a vibrating component supply device.

A vibrating parts supply device is generally also called a parts feeder. According to a spiral parts feeder, a torsional vibration force is applied to a ball forming a spiral track, and the parts ascend on the track and exit from the discharge end of the track. One piece is supplied to the next process. However, in order to discharge the parts one by one, the parts must arrive at the discharge end of the truck in a single layer and in a single row. That is, parts should not overlap or arrive in multiple rows. Traditionally, wipers have been used for this purpose, or the width of the track has been made partially equal to or slightly less than the width of the part. The overlapping parts are removed by the wiper into the ball, and the parts in multiple rows are turned into a single row by the parts in the rows on the inside of the ball in the narrower track section falling into the ball. Corrected. However, when processing parts of different types or shapes, it is necessary to change the mounting position of the wiper or the width of the track portion for single-row correction.

In the figure, the parts feeder is indicated as a whole by 1 and is equipped with a substantially bowl-shaped ball 2. A movable core 3 is fixed to the bottom of the ball 2, which is inclined at a constant angle and connected to a base 5 by a plurality of leaf springs 4 arranged at equal angular intervals. base 5

The torsional vibration drive section that gives known torsional vibration to the ball 2 is composed of the movable core 3, leaf spring 4, electromagnet 6 coil 7, etc. as described above, but these are covered with a cylindrical cover 8. has been done. The entire parts feeder 1 is supported on a foundation by vibration-proof rubber 9.

As shown in FIGS. 2 and 3, a spiral component transfer track 10 is provided on the inner peripheral wall of the ball 2.
is formed. This truck 10 has floor parts T ₁ , T ₂ ,
The width of the side wall portion 11 is constant, but the floor portions T _{1 ,} T ₂ , T ₃
The width of ...... gradually increases toward the bottom. That is, when viewed in the same cross section as shown in Figure 3, if the width of the top floor T ₁ is a, then
The width of the second floor T ₂ is a+b, and the width of the third floor T ₃ is a+2b, and so on. The ball 2 forming such a spiral track 10 was previously disclosed by the present applicant in Japanese Patent Application No. 56-200597, so a detailed explanation thereof will be omitted.

A large amount of rectangular chip resistance m inserted into the center bottom of the ball 2 moves up the track 10 under the torsional vibration force, but as shown in FIG. The material is transported by contacting the material. At the uppermost floor _T1 , the chip resistor m that has been transferred with its front or back surface in contact with the floor falls to the lower floor.

As shown in FIG. 2, the ball side wall of the uppermost part of the track 10 of the ball 2 has markings shown in FIGS. 11 to 14.
A component flow regulating device 12 whose structure is clearly shown in the figure is attached, and a fourth
A component single-layer/single-row ejecting device 13 whose structure is clearly shown in FIGS. 8 to 8 is attached. As will be described later, the component flow rate adjustment device 12 passes through this side. The flow rate of the component m is adjusted, and the component single layer/single row discharge device 13 reliably supplies the component m to one piece.

First, with reference to Figures 4 to 10,
Details of the single-row discharge device 13 will be explained.

In this device 13, a pair of through holes 15 are formed in a mounting block 14 to which various parts are attached.
A pair of screws 16 are inserted through this and fixed to the discharge end of the track 10 of the ball 2. A notch 14a is formed on the lower surface of the mounting block 14, into which a T-shaped floor forming member 19 is fitted, and the mounting block 14 is attached to the discharge end of the track 10 of the ball 2 with a pair of screws 16. Fixed. Fourth
As shown in the figure, a notch 17 is formed at the upper end of the side wall of the ball 2 located below the floor surface forming member 19, and an O-ring 18 is attached to this notch 17. Thereby, the floor surface forming member 19 is allowed to slide smoothly in the direction shown by arrow B.

As shown in FIG. 4, a surface 70 of the mounting block 14 on the inner side of the ball 2 forms the side surface of the component transfer path S, and the transfer path height adjustment block 20 slides into contact with this surface 70 so that the mounting block 14 so that it can move up and down. That is, the block 20 has an L-shaped cross section, and its vertical part 20a is in sliding contact with the mounting block 14, and its horizontal part 20b has a fifth block.
As clearly shown in the figure, a pair of through holes 21 are formed, into which a pair of guide pins 22 implanted in the mounting block 14 are inserted. Also, a pair of through holes 2
An adjustment screw through hole 23 is formed in the center of 1,
Insert the shaft portion 27 of the height adjustment screw 26 into this,
Furthermore, the coil spring 24 is inserted and screwed into the screw hole 25 of the mounting block 14. Coil spring 24 is placed in compression between mounting block 14 and transfer channel height adjustment block 20, urging block 20 upwardly along guide pin 22. As a result, the horizontal portion 20b of the block 20 is pressed against the increased diameter shaft portion 28 of the screw 26. A constant transport path height a is thus maintained. Also, Figures 7 and 9
As shown in the drawings and FIG. 10, a taper 29 is formed on the vertical surface portion 20a of the transfer path height adjustment block 20 on the transfer path entrance side.

A through hole 80 is further formed in the mounting block 14, into which the pin portion 31 of the floor width adjusting device 30 for adjusting the sliding position of the floor surface forming member 19 is inserted. An operating pin 32 is provided at the upper end of the pin portion 31.
are formed integrally extending laterally, and a pair of grooves 33 are formed in the middle part. An O-ring 34 is attached to the groove 33, thereby stabilizing the rotation of the pin portion 31 within the through hole 80. An eccentric engagement part 35 is eccentrically formed at the lower end of the pin part 31, and engages with a long hole 37 formed in the floor surface forming member 19a. Therefore, by rotating the actuating pin 32 around the through hole 80, the floor forming member 19 moves back and forth with its legs 19a being guided by the notched grooves 14a of the mounting block 14. That is, the floor forming member 19 moves in the direction of arrow B as shown in FIGS. 4 and 8, thereby adjusting the floor width b of the transfer path S. The floor surface is formed by the arm portion 19c of the floor surface forming member 19, and the edge portion of the arm portion 19c on the transfer path entrance side is tapered over a predetermined distance 19b. This makes it easier for parts to be removed to fall. After the sliding position of the floor surface forming member 19 in direction B has been adjusted, the pin portion 31 of the floor width adjustment device 30 is tightened by screwing the setscrew 36 into the screw hole 38 formed on the side surface of the mounting block 14. The rotation position is fixed.

Next, details of the component flow rate adjusting device 12 provided upstream of the component single-layer/single-row discharge device 13 configured as described above will be explained with reference to FIGS. 11 to 15.

The component flow rate adjustment device 12 consists of an adjustment screw 39 and a flow rate adjustment block 40, and this block 40 has an arcuate notch 4 formed in the side wall portion 42 of the ball 2.
The ball 2a is rotatably fitted into the ball 2a, and after adjusting the rotational position, the adjustment screw 39 is tightened.
Fixed against. Although the block 40 has a cylindrical shape as a whole, three inclined surfaces 41a, 41b, and 41c are formed on its peripheral side. The slopes of these slopes 41a, 41b, 41c are 12th
As shown in Figures 1 to 14, the angle is the same as the slope of the side wall 11 of the track 10, but the lengths are different as shown. That is, the inclined surface 41
Vertical surface portion 61 connected to each of a, 41b, and 41c
The boundary lines between a, 61b, and 61c form a chord as shown in FIG. 11, and the lengths thereof are different from each other.

In the rotational position shown in FIGS. 11 and 12, the inclined surface 41a and the side wall portion 11 of the truck 10 are aligned, and from the boundary line between the inclined surface 41a and the vertical surface portion 61a to the floor portion _T1 of the track 10. The distance C is approximately equal to the width of the side wall 11 of the track 10, and the width of the adjusted transfer path is maximum. From this rotational position, if the block 40 is rotated clockwise in FIG.
0a protrudes toward the side wall portion 11 of the track 10, as shown in FIG. 15, thereby reducing the width of the transfer path. If it rotates counterclockwise, the inclined surface 41a,
41b protrudes toward the side wall 11 of the track 10, and the width of the transfer path is similarly reduced. As shown in FIGS. 13 and 14, the other inclined surfaces 41b and 41c can also take positions aligned with the side wall portion 11 of the track 10 by rotating the block 40, and the rotation from this rotating position Depending on the amount of movement, the peripheral surface portions 60c and 60a, 60 between these
The amount of protrusion of b toward the side wall portion 11 is changed, and the width of the transfer path is similarly adjusted.
a, 41b, 41c are the sizes of the parts to be processed,
It is selected appropriately depending on the shape.

Although the embodiment of the present invention is configured as described above,
Next, this effect will be explained.

If a large amount of rectangular chip resistor m is inserted into the center bottom of the ball 2 and power is supplied to the drive part, the ball 2 will torsionally vibrate and each part m will move to the track 1.
Rise above 0.

The component applied to this embodiment is a chip resistor, which is in the shape of a rectangular plate, and at the top of the track 10, the long side is in contact with the floor part _T1 as shown in FIGS. 3 and 11. the front or back side of the side wall 11
The tip leans toward the discharge end of the track 10 with its front or back surface leaning against the side wall 11, overlapping the other chip resistors m in the width direction. Therefore, the height a and width b of the component transfer path S in the component single-layer/single-row discharge device 13 are adjusted to be slightly larger than the width and thickness of the chip resistance m, as shown in FIG. Ru. That is, when starting to use this device, the set screw 36 is loosened and the operating pin 32 of the floor width adjusting device 30 is rotated clockwise or counterclockwise in FIG. 6. When the working pin 32 is rotated to the position shown by the solid line in FIG.
When the floor forming member 19 slides to the position shown by the solid line in FIG. 8 and rotates to the position shown by the dashed dot line in FIG. 6, the floor forming member 19 and the position shown by the dashed dot line in FIG. Sliding. The width b of the component transfer path S, ie, the floor width b, is obtained at a certain rotational position of the working pin 32 between the above-mentioned two rotational positions. At this rotational position, tighten the set screw 36 to maintain the floor width b. In addition, in Figures 6 and 8, 1
The dashed dotted line indicates the intermediate position. Next, height adjustment screw 2
6 in the clockwise or counterclockwise direction in FIG. 6, the height adjustment block 20 is moved up and down, and the height a of the component transfer path S is adjusted. The adjusted position is held by a spring 24.

On the other hand, it is assumed that the block 40 of the component flow rate adjusting device 12 is in the rotational position shown in FIG. In other words, it is located at a position where the maximum flow rate is allowed to flow through the chip resistance m. In addition, in FIG. 11 and FIG. 12, the flow path width C at this time is approximately twice the width of the chip resistor m, but as shown in the figure, there is no limit to the overlap of two pieces, and it is possible that the same component m. In some cases, three overlaps may be allowed to pass. When the block 40 is rotated by a certain angle clockwise in FIG. 11, it assumes the rotation position shown in FIG. 15, and statically viewed from the rotation position shown in FIG. 11 to the rotation position shown in FIG. 15. At the rotational position up to, the flow rate of part m remains unchanged, but in reality, the chip resistance m is making a jumping movement, although it is very small.
Since there is also an acting force from the front and rear chip resistances m, the flow rate (number of parts/unit time) of parts passing this side can be continuously changed by rotating the block 40. Note that in the illustrated example, C=width of component m×2, but of course C>width of component m×2
You can also use it as However, in any case, as the block 40 rotates, the peripheral surface 60a of the block 40 acts to obstruct the flow of the parts m, as shown in FIG. The degree of this inhibition is the first
It is almost at its maximum at the rotational position shown in Figure 5.

As described above, the chip resistance m of the flow rate corresponding to the component flow rate adjustment by the component flow rate adjustment device 12 reaches the component single-row/single-layer discharge device 13, but after passing through the component flow rate adjustment device 12, the chip resistance m that overlaps again m′,
Alternatively, when a large amount of chip resistance m is introduced into the ball 2, the chip resistance m distributed on the downstream side of the component flow rate adjustment device 12 overlaps the component single-row/single-layer discharge device 1.
When the chip resistance m' reaches 3, the height adjustment block 20 is adjusted as shown in FIGS.
The ball 2 falls smoothly into the interior of the ball 2 under the guide action of the inclined surface 29 . The chip resistor m from which the overlap has been removed continues to move forward along this transfer path S.
One by one, each piece is supplied to the next process. The chip resistors m that have reached the component single-row/single-layer discharge device 13 without overlapping, that is, in a single layer state, naturally proceed as they are along the transfer path S and are sequentially supplied to the process one by one. According to this embodiment, the next step is a counter, which counts the number of chip resistors m that are sequentially discharged.

In order to increase the counting speed, it is necessary to increase the component discharging speed of the component single-row/single-layer discharging device 13, but according to this embodiment, this can be further improved. In other words, if the component supply speed to the component single-row/single-layer discharge device 13 is too high, interference may occur between successive components m, or interference between component m and the entrance to the component single-row/single-layer discharge device 13. As a result, the speed at which parts are ejected from the ejection device 13 is reduced. Of course, if the component supply speed to the ejection device 13 is too low, the component ejection speed will also be reduced. According to the present invention, this is the component flow rate adjusting device 1.
Optimization can be achieved by adjusting the component flow rate in step 2. That is, the flow rate of the parts passing through this side is adjusted by the parts flow rate adjusting device 12 so that the counting speed of the counter for the parts from the single-row/single-layer parts discharging device 13 is maximized.

When a chip resistor n having a smaller width is to be processed, the component flow rate adjusting device 12 is used as shown in FIG.
By utilizing the inclined surface 41b, the transfer path width becomes the maximum d, and the maximum flow rate in this case is regulated. Again, in this case, block 4
Optimization is performed by rotation of 0. When a chip resistor O having a smaller width is to be processed, the slope 41c is used in the component flow regulating device 12 as shown in FIG. 14, so that the maximum flow rate in this case is regulated and Optimization is performed by rotation. In this embodiment, for various chip resistances m, n, and o, which slope surface 41a,
Although it is possible to adjust the flow rate using the slopes 41b and 41c, it is possible to adjust the flow rate more precisely by using the corresponding inclined surfaces 41b and 41c as shown in FIGS. 13 and 14. Also, for a constant chip resistance, the slopes 41a, 41b, 41
c on the side wall 11 of the track 10.
The parts flow rate may be adjusted in three stages by arranging the parts as shown in FIG. 1, FIG. 13, and FIG. 14.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited thereto, and various modifications can be made to the technical idea of the present invention.

For example, in the embodiments described above, the present invention was applied to the ball 2 that was previously developed by the applicant, but it is also applicable to balls that have been widely used in the past. For example, FIG. 16 is a partial cross-sectional view of a ball 50 having a constant track width (floor width). may be provided. Also, in this ball 50, the part P' is the floor part 5.
Even when the same part P is transferred while lying on the side wall 51, it can pass through the single-layer/single-row part discharging device 13 even when the same part P is transferred while leaning against the side wall part 51. That is, even if the width and height of the transfer path are adjusted as shown in FIG. As it progresses, it falls sideways as shown by the arrow,
It assumes the attitude shown at P' and is discharged from the device 13.
This improves the parts supply speed.

Further, in the above embodiment, the block 40 of the component flow rate adjusting device 12 has three inclined surfaces 41a, 41b, 4
Although 1c is formed, only one inclined surface or four or more inclined surfaces may be formed.
Further, in the above embodiment, the inclined surfaces 41a, 41b, 4
1c can be aligned so that it is flush with the side wall 11 of the truck 10, but the inclined surface 41 is not flush with the side wall 11 of the truck 10.
The levels of a, 41b, and 41c may be made higher.

Furthermore, in the above embodiments, this device was used to count the number of chip resistors m, but depending on the shape of the parts, it can also be used to align and supply parts.

Further, in the above embodiment, the component flow rate adjusting device 12 was provided at one location on the ball 2, but it may be provided at multiple locations to optimize the component supply speed by mutually adjusting the flow rate.

As described above, according to the vibrating parts feeding device of the present invention, the speed at which the ball feeds parts one by one with a constant swing width is increased compared to the conventional one, while making it easy to adjust parts into a single row or single layer. Moreover, this device can be applied to various parts.
