Description

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

The vibrating parts feeding device is generally also called a parts feeder.
According to a spiral type parts feeder, a screw vibration force is applied to a ball forming a spiral track, and the parts ascend on the track and are fed one by one to the next process from the discharge end of the track. 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. In other words, parts must 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 inward by the wiper, and the parts in multiple rows fall into the inside of the ball at the track section where the width is reduced by /J'%. It was straightened into a single row. 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. Changing the mounting position of the wiper is easy, but changing the width of the track part is troublesome because it requires reworking the track and replacing it with another ball.

2) The screw vibration drive unit that gives the known screw vibration is composed of the movable core (3), the plate spring (4), and the electromagnet (6) as described above.
) coils (7), which are covered by a cylindrical cover (8). The entire parts feeder (1) is supported on the foundation by anti-vibration rubber (9).

As shown in FIGS. 2 and 3, a spiral component transfer track aO is formed on the inner peripheral wall surface of the ball (2). This track 0 (many is floor part '11% T', '14
The width of the side wall part αη is constant, but the width of the floor part T,...
The widths of T, , T, . . . gradually increase toward the bottom. That is, when viewed from the same cross section as shown in Fig. 3, if the width of the top floor T1 is shifted from a, the width of the second floor T1 is a+b, and the width of the third floor T1 is a+b. The width of the floor portion T gradually increases as follows.

Regarding the ball (2) forming such a spiral gorge track Oq, the present applicant previously filed a patent application filed in 1983-
Since it is disclosed in No. 200597, detailed explanation of the bond will be omitted.

A large amount of rectangular chip resistor m inserted into the center bottom of the ball (2) receives the vibration force of the screw 9 and moves upwards on track 0 (body), but as shown in Fig. 3, most of it is on the surface or The chip resistor m is transferred with its back side in contact with the side wall Qυ.At the top floor T, the chip resistor m that has been transferred with its front side or back side in contact with the floor falls to the lower floor. .

As shown in Figure 2, a component flow adjustment device # (6) whose structure is clearly shown in Figures 11 to 14 is attached to the side wall of the pole at the top of the track OO of the ball (2). Furthermore, a component single-layer/single-row discharge device #0 whose structure is clearly shown in FIGS. 4 to 8 is attached to the discharge end of the truck OQ. As will be described later, the parts flow rate adjustment device (b) passes through this side blade. The flow rate of the component m is adjusted, and the component single layer/single row discharge device (to) reliably supplies the component m to one piece.

The details of the component single-layer/single-row discharging device (2) will now be described with reference to FIGS. 4 to 1O.

In this device (C), a pair of through holes (C) are formed in the mounting block α4 for attaching various parts, and a pair of screws (2) are inserted into the holes to connect to the discharge end of the track 01 of the ball (2). Fixed. A notch (14a) is formed on the lower surface of the mounting block α, into which the T-shaped floor forming member 0I is fitted, and the mounting block α is fitted with a ball (14a).
It is fixed to the discharge end of the track tJ1 in 2) with a pair of screws (A). As shown in FIG. 4, a cut 9 force is formed at the upper end of the side wall of the ball (2) located below the floor surface forming member α, and an O ring (T) is attached to this. Thereby, the floor surface forming member 4 can be smoothly slid in the direction shown by the arrow B.

As shown in FIG. 4, the surface σl on the inner side of the ball (2) of the mounting block α→ forms the side surface of the component transfer path S, and the transfer path height adjustment block is in sliding contact with this surface ff1). A fence is attached to the mounting block α4 so as to be vertically movable. In other words, the block (E) has an L-shaped cross section, and its vertical part (20a) is in sliding contact with the mounting block α, and its horizontal part (20b) has a pair of through holes as shown in FIG. A hole CD is formed, into which a pair of guide bins (2z) implanted in the mounting block (b) are inserted.Also, an adjustment screw through hole @ is formed in the center of the pair of through holes Qυ.
Insert the shaft part (2) of the height adjustment screw (E) into this, and then insert the coil spring 41 into the mounting block α.
Screw it into the screw hole (c) of the screw.

A coil spring (241) is compressed between the mounting block (α) and the transfer path height adjustment block (1), and urges the block (1) upward along the guide pin (2).

As a result, the horizontal part (20b) of the block (E) is screwed (
(to) is pressed against the diameter-increasing shaft part. Therefore, a constant transfer path height a is maintained. In addition, as shown in FIGS. 7, 9, and 10, the vertical surface portion (
A taper (21) is formed on the transfer path entrance side of 20a).

The mounting block a4 is further formed with a through hole (2), into which is inserted the bottle part c3° of the floor surface adjustment device 1 (3I) for adjusting the sliding position & of the floor surface forming member 4. Oυ
At the upper end, an operating bottle (3) extends to the side blade and is integrally formed, and a pair of grooves (G) are formed in the middle part.The grooves (C) have an O-ring (B) is attached, thereby stabilizing the rotation within the through hole ■ of the shim part 0υ.Six eccentric engaging parts are formed eccentrically at the lower end of the bin part OI), which are connected to the floor surface. Legs (19a) of forming member 09
It is engaged with a long hole (37) formed in. Therefore, by rotating the actuating bin I33 around the periphery of the through hole, the floor forming member α moves back and forth with its legs (19a) being guided by the notch grooves (14a) of the mounting block αa. That is, the floor forming member 4 moves in the direction of the arrow as shown in FIGS. 4 and 8, thereby adjusting the floor surface of the transfer path S. The floor surface is formed by the arm portion (19c) of the floor forming member α group, and the edge portion of the arm portion (19c) on the transfer path entrance side is tapered (19b) over a predetermined distance. This makes it easier for parts to be removed to fall. B of floor forming member α
After the sliding position in the direction is adjusted, set screw 06)
Screw holes (c) formed on the side of the mounting block (b)
By screwing and tightening, the rotational position of the bin part (3I) of the p-floor intermediate adjustment device (to) can be fixed.

Next, component single-layer/single-row discharging device C configured as above
Details MBK of the component flow rate adjusting device (2) provided on the upstream side of L1 will be explained with reference to FIGS. 1I to 15.

The parts flow rate adjustment device (b) consists of 6 adjustment screws and a flow rate adjustment block (4G), this block (401 is a ball (
2) with an arc-shaped notch (42a) formed on the side wall (4).
), and after adjusting the rotation position, it is identified to the ball (2) by tightening the adjusting screw (31).The block (41 has a cylindrical shape as a whole, but its circumference Three inclined surfaces (41a) (41b) on the sides
) (41c) are formed. These inclined surfaces (41a
)(41b) and (41c) are at the same angle as the inclination of the side wall portion aυ of the track 00 as shown in FIGS. 12 to 14, but their lengths are different from each other as shown. That is, the boundary lines between the vertical surfaces (61a), (61b), and (61) connected to the inclined surfaces (41aX41b bars 41C) form a chord as shown in FIG. 11, and the lengths thereof are different from each other.

In the co-movement position shown in Figs. 11 and 12, the inclined surface (41
a) and the side wall portion Qυ of the truck 00 are aligned 8, and the distance C from the boundary line between the inclined surface (41a) and the vertical surface portion (61a) to the floor portion T of the truck 00 is the side wall portion of the truck 00. The width of C1η is equal to 1] of the adjusted transfer path.
is the maximum. From this rotational position, if the block (41) is rotated clockwise in FIG.
a) (The peripheral surface part (60a) between 4 and 10 protrudes toward the side wall part 0 of the trunk OQ as shown in FIG. 15, thereby reducing the width of the transfer path. In the counterclockwise direction When rotated, the peripheral surface (60b) between the inclined surfaces (41a and 41b) protrudes toward the side wall of the track α0, and the width of the transfer path is similarly reduced.Other inclined surfaces (41b) (41c) is also the 13th
As shown in the figure and FIG. 14, by rotating the block +40, it is possible to take a position FKk that is aligned with the side wall portion 0υ of the track 01, and the amount of rotation from this rotation position 1 lock is as follows:
Peripheral part (60C) and (60aX60b) between these
The amount of protrusion toward the side wall αη side is changed, and the width of the transfer path is similarly adjusted.
(41c) can be selected as appropriate depending on the size and shape of the part to be processed.

The embodiment of the present invention is constructed as described above, and its operation will be explained next.

Rectangular chip resistor ml: When a large amount of chip resistor ml is put into the center bottom of the ball (2) and power is supplied to the drive part, the ball (2) will vibrate by 9 screws and each part m will rise on the track OQ. .

The component applied to this embodiment is a chip resistor, which has a long sword-shaped plate shape, and at the top of the track αQ, the long side touches the floor T1 as shown in FIGS. 3 and 11. When the front or back surface is leaning against the side wall 0υ, the front or back surface overlaps the other chip resistor m in the width direction.
Head toward the discharge end of truck 00 while leaning against wall CIIJ. Therefore, the height a and width of the component transfer path S in the component single-layer/single-row discharge device (2) 8 are slightly larger than the width and thickness p of the chip resistor m, as shown in FIG. It is adjusted so that That is, when starting to use this device, loosen the setscrew (3) and rotate the working bin 0 of the vertical floor width adjustment example clockwise or counterclockwise as shown in FIG. 6. The working bin history is indicated by the solid line in Figure 6.
When the floor forming member 01 is rotated to JI, the floor forming member 01 slides to OK as indicated by the solid line in Fig. 8 when it is α, and when it is rotated at mt as indicated by the dashed line in Fig. N6, the floor forming member 01 is The width b1 of the three-component transfer path S, which slides up to the position t indicated by the dashed line in FIG. At this rotational position, tighten the setscrew t313) to hold the floor insert. In addition, in FIGS. 6 and 8, the two-dot chain line indicates the intermediate position. Next, move the height adjustment screw (28I clockwise or counterclockwise in FIG. 6 to adjust the height iIA block) to the vertically movable parts transfer path S.
The height a of is adjusted. The adjusted position is held by a spring (2).

On the other hand, it is assumed that the block (1[) of the component flow rate adjustment device (2) is in the rotational position shown in FIG. 11. In other words, it is located at a position where the maximum flow rate is allowed to flow through the chip resistor m. In addition, in FIGS. 11 and 12, C in the flow path at this time is approximately twice the width of the chip resistor m, but as shown in the figure, the width of the same component m is limited to a maximum of two overlapping parts m. However, there are cases where three overlapping lines are allowed to pass. If the block +41 is rotated by a certain angle δ in the clockwise direction from VC in FIG. 11, it will take the rotational position shown in FIG. At the rotational position up to the rotational position, the flow rate of the component layer remains unchanged, but in reality, the chip resistance m undergoes a jumping movement, although it is very small.
Since there is also an acting force from the block (410), it is possible to continuously change the flow rate (number of parts/unit time) of parts passing through this side by rotating the block (410).

In the illustrated example, C is the width of the part m x 2, but it is of course possible to set q>the width of the part m x 2. However, in any case, due to the rotation of the block (4cJ), the peripheral surface (60a) of this block (41) acts to obstruct the flow of the parts m, as shown in FIG. 15.

The degree of this inhibition is maximum at the rotational position shown in FIG.

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 (6) reaches the component single-row/single-layer discharge device fjIta3, but after passing through the component flow rate adjustment device (6), the chip resistance m overlaps again. When a large number of chip resistors m' are loaded into the ball (2), the chip resistors m distributed on the downstream side of the component flow control device (2) are overlapped to form a component single-row/single-layer discharge device (toward). The chip resistance m′
is the height adjustment block (as shown in Figures 9 and 10).
7) Inclined surface c! The ball (2) falls smoothly into the interior of the ball (2) under the guiding action of (2).

Heavy! The chip resistors m from which 5'i' have been removed continue to advance and are sequentially supplied to the next process from this transfer path S. The chip resistors m that have reached the component single-row/single-layer discharge device (2) without overlapping, that is, in a single layer state, of course proceed as they are through the transfer path S, and are supplied to the first-order one-by-one process. 3 According to this embodiment, the next step is a counter, which counts the chip resistors m that are sequentially discharged.

In order to increase the counting speed and noise, it is necessary to increase the component ejection speed of the component single-row/single-layer ejection device (to), but this embodiment can further improve this. In other words, if the component supply speed to the single-row/single-layer component discharging device filiQ3 is too high, interference between overlapping parts m, interference between consecutive parts m, or interference between part m and the single-row/single-layer component may occur. Due to interference at the entrance to the ejection device (c), the speed at which parts are ejected from the ejection device 101 is rather reduced.

Of course, even if the component supply speed to the ejection device 03 is too low, the component ejection speed will be reduced. According to the present invention, this can be optimized by adjusting the component flow rate using the component flow rate adjustment device*(2). In other words, a component single row/single layer ejection device (l
The flow rate of the parts that pass through this side is adjusted by the parts flow rate adjustment device (6) so that the counting speed of the counter that counts the parts from the side is maximized.

If a chip resistor n with a smaller width is processed, the first
As shown in Fig. 3, the slope (41b) is used in the component flow rate regulating device 1r (2), so that the maximum flow rate in the transfer path is regulated. . Again, in this case, p optimization is performed by rotating the block (4 (I). If a chip resistance 0 with a smaller width is to be processed, the component flow rate adjustment device (2) as shown in FIG.
By using the inclined surface (410),
In this case, the maximum flow rate is regulated, and optimization is performed on the rotation of block +4 (l. In this example, the maximum flow rate is q!
Which inclined surface (41
Although it is possible to adjust the flow rate using the aX41bX41 ratio, it is also possible to finely adjust the flow rate by using the corresponding inclined surfaces (41b) (41C) as shown in FIGS. 13 and 14. In addition, for a constant chip resistance, one of the inclined surfaces (41a) (41b) (41) is placed on the track (II (71) 0111
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 above embodiments, the present invention was applied to the ball (2) developed by the present applicant, but it can also be applied to balls that have been widely used in the past. For example, FIG. 16 is a partial cross-sectional view of a ball 6Q having a constant track width (inside the floor). (2)
may be provided. Also, in this ball 601, the parts -
Even if the same part P is transferred lying on the floor, or if the same part P is transferred next to the side wall (511), the single-layer/single-row part discharging device (passing through Ll) In other words, even if the width and height of the transfer path are adjusted as shown in FIG. Due to the action of the taper (on the adjustment block), as it advances, it falls sideways as shown by the arrow, and is ejected from the vertical weight ω, taking the position shown as P'.This increases the multi-component supply speed. will improve.

In addition, in the above embodiment, three inclined surfaces (41a) (41b) (41) were formed on the block t41 of the component flow rate adjustment device @, but only one inclined surface was The above sloped surfaces may be formed.Also, in the above embodiment, the sloped surfaces (41a) (41b) (41c) can be aligned so as to be flush with the side wall cIυ of the track 01. Slanted surface instead of flush (41aX41b) (41C)
The level may be set to be much higher.

In the above embodiments, this device is used to count the number of chip resistors m, but depending on the shape of the components, it can also be used to align and supply components.

In addition, in the above embodiment, the component flow rate adjusting device Ii (b) was provided at one location on the ball (2), but it is possible to install it at multiple locations to optimize the multi-component supply speed by mutually adjusting the flow rate. You can also do this.

As described above, according to the vibrating component supply device of the present invention,
The speed at which parts are fed one by one for a given swing width of the ball can be significantly improved compared to the conventional system, and the device i'' can be applied to various parts.
