Description

[Detailed Description of the Invention] The present invention relates to a component removal device in a vibrating component feeder.

FIG. 1 shows a conventional example of a vibrating parts feeder. In the figure, this vibrating parts feeder is indicated as a whole by 1, and is also called a parts feeder, but it has a nearly bowl-shaped parts receiver 2. (hereinafter referred to as a ball), and a track 3 is formed in a spiral shape inside the ball. A torsional vibration drive unit is coupled to the lower part of the ball 2, thereby causing the ball 2 to perform torsional vibration. Due to this vibration, the part m on the track 3 is transported along the track 3 and biased towards the side wall. The track 3 is inclined downward in the radially outward direction of the ball 2. The track 3 is provided with arcuate and stepped notches 4a and 4b for aligning the parts m in a line and for dropping the parts m lying sideways. Further, a notch is formed in a part of the side wall portion 2a of the uppermost portion of the track 3, and the wiper block 5 is fixed with a screw 6 by fitting into the notch. Although the wiper block 5 is not shown, the lower surface of the portion protruding toward the track 3 side and the track 3
A space slightly larger than the thickness of the part m is formed between the parts transfer surface and the overlapping part m, and the overlapping part m is removed here. At this time, the overlapping parts m are guided by the slope 5a, and the overlap is smoothly removed. Furthermore, on the downstream side, a component-overturning block device 7, clearly shown in FIG. 2, is fitted into a notch in the side wall portion 2a.
The parts m are supplied to the outside from the track discharge end 8 one by one in a desired posture.

In FIG. 2, the component overturning block device 7 consists of a substantially semi-cylindrical block 9, and a ball 2
It fits into the notch 2b of the side wall portion 2a. Insert the screw 12 into the through hole 11 of the block 9, and insert the screw 12 into the notch 2b.
The block 9 is fixed to the ball 2 by screwing it into a screw hole 2c formed on the bottom surface of the ball 2.
An arcuate notch 10 is formed in a portion of the block 9 that projects inward from the notch 2b of the ball 2, and the component m, which is in a standing position, is now tipped over to take a lying position. The bottom of the notch 10 is the track 3
is higher than the transfer surface of m, and this step is smaller than the thickness of part m. The lying part m thus advances along the step without entering the notch 10.

The conventional vibrating parts feeder 1 has the above-mentioned configuration and functions, but before use, the ball 2
A large number of parts m are put into the container. It should be noted that the parts m are shown scattered in order to make the diagram easier to understand.
Part m is delivered from the track discharge end 8 in the desired posture.
Although parts are supplied individually, there are cases where it is desired to change the type of parts to be supplied. In such a case, if a large number of parts m remain in the ball 2, it will take a long time to wait for all of them to be discharged from the track discharge end 8. Furthermore, since various devices (not shown) are actually connected to the truck discharge end 8, it would take too much time to wait for all of these devices to be discharged from the most downstream side. In order to deal with this, conventionally, for example, the block 9 of the block device 7 for overturning parts is removed. The part m is expelled to the outside through the notch 2b in the side wall 2a of the ball 2.
There is a screw hole 2c on the bottom of the notch 2b, and the supply part m is very small (for example, a chip resistor).
Therefore, the part m often gets stuck in the screw hole 2c. This not only prevents removal of subsequent parts m, but the deeper the screw hole 2c, the more parts will fit into it, so when reinstalling the block 9, all the parts in the screw hole 2c must be removed. This requires very tedious work. The parts are small,
Since the diameter of the screw hole 2c is also small, it is impossible to pick it out with your fingers.

Further, the removed block 9 and screw 12 are placed somewhere outside the ball 2, but it is conceivable that the user may forget where they are placed or lose them.

The present invention has been developed in view of the above-mentioned problems, and provides vibrating components that can be quickly removed from the ball without the components clogging the screw holes, and eliminate the need to lose components for this purpose as in the past. The purpose of this invention is to provide a parts removal device for machines. According to the present invention, this purpose is to provide a vibrating parts feeder that uses vibrations to transfer parts along a predetermined transfer path and biased toward the side wall of the transfer path. A cutout is formed in the bottom wall surface having no hole at the same level as or lower than the transfer path, and a block that fits into the side wall surface of the cutout is attached to one end of the lever. A screw member through which the other end of the lever is inserted is screwed into a screw hole formed in the side wall and tightened to be fixed to the side wall, and the opening of the notch on the transfer path side is connected to the block. When removing the parts, the screw member is loosened and the lever is rotated around the axis of the screw member to close the notch and form a part of the side wall of the transfer path. The block is moved outward from the opening on the transfer path side, the screw member is tightened into the screw hole to fix the block in the open position, and the block is moved through the bottom wall surface from the opening on the transfer path side of the notch. This is achieved by a parts ejecting device characterized in that the parts are ejected to the outside.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 13.

3 to 9 show a first embodiment of the present invention. In the figures, the vibrating component feeder is indicated as a whole by 20, and its ball 21 is approximately round shaped, and a movable core 22 is attached to the bottom of the vibrating component feeder. is fixed, and is coupled to the base 23 by a plurality of leaf springs 26 arranged at equal angular intervals. An electromagnet 25 having a coil 24 wrapped around it is fixed on the base 23. The movable core 22, the leaf spring 26, and the electromagnet 25 constitute a torsional vibration drive section, which is covered with a cylindrical cover 27. Further, the entire vibrating component feeder 20 is supported on the foundation by vibration isolating rubber 28.

As shown in FIG. 4, a spiral track 29 is formed inside the ball 21, and in the uppermost part of the track 29, a parts removal device 30 according to the present invention, a notch 31 for single-row alignment, and a wiper are installed in order from the upstream side. A blocking device 32, a notch 33 for laying down parts, and a notch 34 for second single-row alignment are provided, and the track discharge end 3
Parts m from 5 are supplied to the outside in a desired posture one by one.

The parts removing device 30 mainly consists of a block 37, a lever 38 and a screw member 39. Block 3
7 has a shape like a part of a cylinder cut out in the axial direction, and a part of the side wall part 21a of the ball 21, that is, a part of the side wall part of the uppermost part of the track 29, has a notch so that this part can be fitted. 36 are formed.
Further, the bottom surface 44 of the notch 36 is located at a position slightly lower than the component transfer surface of the track 29.

Further, a screw hole 37a is formed on the upper surface side of the block 37, as shown clearly in FIG. be screwed on. That is, the block 37 is integrally fixed to one end of the lever 38.

Further, a screw hole 43 is formed on the upper surface of the side wall portion 21a of the ball 21, as clearly shown in FIG.
A through hole 3 formed at the other end of the lever 38
A screw member 39 inserted through 8a is screwed with a washer 41 interposed. Although some kind of tool is required to tighten the screw 40 mentioned above into the screw hole 37a of the block 37, the screw member 39 can be tightened into the screw hole 43 by operating the disc-shaped knob 39a with your fingers. . The same applies when loosening.

When the screw member 39 is loosened slightly, the lever 38 can be rotated around the axis of the screw member 39.
As shown in FIG.
7b is the opening 36a of the notch 36 on the track 29 side.
The screw member 39 is tightened at the position where it is closed. Further, a notch 45 is formed in the side wall portion 21a of the ball 21 so as to face substantially the center of the lever 38. This reduces the sliding surface between the lever 28 and the side wall 21a of the ball 21, making it easier to swing the lever 28.

As clearly shown in FIG. 8, the single-row alignment notch 31 consists of arcuate and step-like notches 46a and 46b formed in the side wall of the lower track 29, and an upper notch. Track 2 by 46a
9 is partially made into a narrow path 29a. This narrow road 29
The width of a is slightly smaller than the width of component m. Among the parts m that arrived here in multiple rows, all the parts m in the row on the inside of the ball 20 have the notches 46a and 46b.
Through the
Only the parts m in the outermost row of balls proceed further downstream. Note that the second single-row alignment notch 34 located further downstream is similarly configured.

The wiper block device 32 mainly consists of a block 47, as shown in FIG.
is fitted. It is fixed to the ball 21 with a countersunk screw 49. There is a gap between the lower surface of the part of the block 47 protruding toward the track 29 side and the part transfer surface of the track 29, and this height h is greater than the thickness of the part m, but is more than twice this thickness. small. In addition, a linear slope 50 is provided on the peripheral side of the block 47.
is formed, thereby allowing the overlapping parts m to be smoothly removed.

Next, with reference to FIG.
I will explain about it.

This notch 33 is formed in an arc shape along the vertical direction of the side wall portion 21a of the ball 21, and its bottom surface is slightly higher than the component transfer surface of the track 29. That is, a step 33a is formed. The lying part m continues along the step 33a, but the part m' standing vertically and the part m'' standing horizontally reach the notch 3.
3 and is transported along the arcuate wall of the notch 33 in a lying position, and guided into the track 29.

Note that the track 29 is connected to the ball 21 as before.
(9th
(see figure).

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

First, there is a large amount of parts m in the center of the ball 21.
(for example, a very small chip resistor) is introduced. When the torsional vibration driving section is driven, the ball 21 undergoes torsional vibration, and the component m is transferred along the track 29 and biased toward the side wall. When the block 37 reaches the position of the parts removing device 30, as shown in FIG. 6, since the block 37 has closed the opening of the notch 36, it continues to advance along the circumferential surface 37b of the block 37. When reaching the single-row alignment notch 31, the plurality of rows of parts m are arranged in a single row, and the parts m further advance toward the wiper block device 32.

In the wiper block device 32, the overlapping parts m are guided by the slope 50 of the block 47 and dropped to the side. Therefore, on the downstream side of the block 47, the component m continues to advance on the track 29 in a single layer until it reaches the notch 33 for laying down the component. As shown in FIG. 5, the part m' that stands vertically and the part m'' that stands horizontally fall sideways into the notch 33 that is concave in an arc shape, and take a lying position. It advances along the wall surface and is guided onto the track 29. Furthermore, the parts m lying sideways in the single-row alignment notches 31 and 34 are also dropped onto the lower track 29. From the discharge end 35, the parts m are supplied to the outside in a lying position with the longitudinal direction facing the transfer direction.

The parts m in the ball 21 are arranged as described above and supplied to the outside, but there may be cases where it is desired to change the type of parts to be supplied when a large number of parts m remain in the ball 21. be. In such a case, rotate the knob 39a of the screw member 39 of the component removal device 30 with your fingers in the direction of the arrow to loosen the screw slightly. Next, the lever 38 is rotated in the direction of the arrow A shown in FIG. 6 to place the block 37 in a position outside the ball 21. Thus, as shown in FIG. 7, the notch 36 formed in the side wall portion 21a of the ball 21 is placed in an open state. Since the component m advances toward the side wall portion 21a, it is guided into the notch 36 and is discharged to the outside through the bottom surface 44 of the notch 36. Note that a chute may be connected to the outside of the notch 36, and the component may be accommodated in some kind of container through this chute.

As described above, the component m remaining in the ball 21 is quickly removed to the outside, but since there is no screw hole in the bottom surface 44 of the notch 36 as in the conventional case, Therefore, the part m is smoothly removed from the outside without becoming clogged or having its flow obstructed.

In addition, the component removing device 30 does not remove the block 37 from the ball 21, but instead positions the block 37 outward from the notch 36 and attaches it to the ball 21.
7, this can be done immediately and all that is required is to operate the knob 39a of the screw member 39 with your fingers and tighten it, so that parts removal work and notch closing work can be done quickly. I can do it. Furthermore, there is no possibility that the parts removal device 30 will be lost.

10 and 11 show a component ejecting device for a vibrating component feeder according to a second embodiment of the present invention. Note that the same reference numerals are given to parts corresponding to those in the first embodiment, and detailed explanation thereof will be omitted.

In the component removal device 51 of this embodiment, as clearly shown in FIG. 11, an arc-shaped notch 53 is formed in the portion of the block 52 that projects into the ball 21. Its bottom surface is slightly higher than the transport surface of the track 29, forming a step 53a. That is,
This block 52 performs the same function as the component horizontal notch 33 in the first embodiment. Therefore, in the case of this embodiment, the notch 33 formed in the side wall of the ball 21 for laying down the component sideways can be omitted. It is easier to form such a notch 33 in the block 52 than in the ball 21. The parts removal work and the notch 36 closing work are the same as in the first embodiment.

12 and 13 show a component ejecting device for a vibrating component feeder according to a third embodiment of the present invention. Note that parts corresponding to those in the first embodiment are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In the component removal device 54 of this embodiment, as clearly shown in FIG. The upper part 55b is slightly protruded into the ball 21. A space corresponding to h in FIG. 9 is formed between the lower surface of the upper portion 55b and the transport surface of the track 29. That is, when the block 55 closes the notch 36, the parts removing device 54 is in the ninth position.
It performs the same function as the wiper block device 32 shown in the figure. Therefore, in this embodiment, such a wiper block device 32 can be omitted. Regarding parts removal work and notch 36 closing work, please refer to Part 1.
This is similar to the example.

Each embodiment of the present invention has been described above, but
Of course, the present invention is not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, a so-called helical parts feeder having a spiral track has been described, but the present invention is also applicable to a so-called linear parts feeder having a straight track.

Furthermore, in the above embodiment, the parts removal devices 30, 5
Although only one ball 21 of the vibrating component feeder 20 is provided with numerals 1 and 54, two or more may be provided.

Further, in the above embodiments, the blocks 52 and 55 are provided with a wiper function or a component sideways function, but they may be formed to perform other sorting functions.

As described above, according to the component removal device of the vibrating component feeder of the present invention, the screw holes are not clogged with components, and the remaining components can be promptly removed to the outside. Since there is no need to remove stuck parts, the equipment can be operated quickly.
There is no chance of losing device components.
