Abstract

PURPOSE:To line up screws, pins and the like in a short time by forming a lining-up plate with numbers of part lining-up holes so that it can be fixed stationarily in a vibrating device which can be tilted by a tilting device. CONSTITUTION:A vibrating body 13 is tilted to the left for example, by cylinders 22 and 23 around a tilting shaft 21 so as to let parts such as screws and the like be housed in a part lining-up plate 30. Under this situation, the vibrating body 13 is vibrated in the longitudinal direction. And the rod of the left cylinder 22 is gradually extended simultaneously, and the rod of the right cylinder 23 is gradually contracted. This permits the vibrating body 13 to be gradually shifted from left tilting to right tilting. During the process, screws in the part lining-up plate 30 are vibrated, and are moved from the left side to the right side within the plate so as to get into the lining-up holes 31 of the plate 30. The longitudinal vibration and the shift in the tilting direction is repeated so that all the parts are lined up so as to be in the lining-up holes. By this constitution, the parts can be lined up efficiently in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention is a vibrating parts aligning device, more specifically, a device for aligning a large number of parts in aligning holes of a parts aligning plate by using longitudinal vibration and reciprocating tilting motion. The present invention relates to a vibrating component alignment device.

[Prior Art] Conventionally, various types of vibration generators have been provided.

Many such vibration generators have been used to generate vibrations in the linear direction by reversing reciprocating pressure in the -axial direction.

Specifically, we use a vibration generating device that converts eccentric interlocking by an eccentric cam fixed to the output shaft of a motor into repetitive linear motion, or a repetitive linear interlocking that utilizes the movement of a cylinder back and forth by excitation and demagnetization of an electromagnetic solenoid. Vibration generators, etc., were provided.

Also, what are the uses of such a vibration generator?

In addition to so-called vibrating sieves, they were widely used for transferring materials or for sieving parts in parts feeders and the like.

[Problems to be Solved by the Invention] However, with such conventional vibration generators, although it is possible to simply generate vibrations, it is difficult to determine the direction of the vibrations.
・Because it was in the axial direction, there were technical fields that were difficult to apply.

Particularly in recent years, as parts have become smaller, automated lines have come into use in which small parts are assembled onto workpieces by robots attached to the assembly line.

In such a line, small parts are always fed to a fixed position so that the Roponto manipulator can easily take them out, or the parts are arranged in a parts alignment tray formed in a fixed shape, and the Roponto manipulator is able to easily take out the small parts. (7) It has become necessary for the manipulator to assemble the parts while taking them out one by one from the parts alignment tray.

However, it is difficult to feed small parts, such as screws with small diameters, or long and directional parts such as pins, to a certain position using a parts feeder. It was also difficult to arrange the parts on a single-part arrangement tray.

There it was unreleased [! 1 applies vertical vibration to the component alignment plate, makes it possible to tilt the vibrating device itself that performs the vertical vibration, and has an alignment hole for aligning the components in the vibrating device. A large number of sunken parts alignment plates are fixed, and vertically long parts such as screws 1 with small diameters or pins with different directionality are aligned with the alignment holes of the parts alignment plate by vertical vibration. It is an object of the present invention to provide a vibrating component alignment device that can efficiently align components in an extremely short time. - [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention includes a vibration generator that generates vertical vibrations and a tilting device that tilts the vibration generator. It is assumed that the #+j feature is that the generator is provided with a component alignment tray with a large number of alignment holes for aligning components in a fixed iTf capacity.

[Operation] According to the present invention, by simultaneously operating the tilt device and the vibration generator, the vibrating body vibrates in the vertical direction while tilting.

Therefore, when a large number of objects to be vibrated are placed on a component alignment tray fixed to the vibrating body, the objects to be vibrated move along the inclination of the vibrating body and are subjected to longitudinal vibrations caused by the vibrating device.

When subjected to such vertical vibration, the vibrated object in the part-aligned blood vibrates in the vertical direction, resulting in a so-called undulating state.

When the object to be vibrated vibrates in the vertical direction and enters the idling state in this way, the object to be vibrated enters the alignment hole of the component alignment pan. The Rukoto.

Further, since the unreleased part II tilts while vibrating, the objects to be vibrated are evenly positioned in the alignment holes of the component alignment plate.

The present invention is particularly effective for aligning screws with small diameters or vertically long and directional parts such as pins, because the objects to be vibrated are aligned in a so-called Odor shape 7g due to vibration. .

[Example] Embodiments of the present invention will be described below with reference to illustrated examples.

FIG. 1 is a front view showing an embodiment of the vibrating component alignment device, and FIG. 2 is a detailed sectional view of the vibration generator 10 used in the vibrating component alignment device shown in FIG. 3 is a perspective view of the component alignment plate 30, FIGS. 4 and 5 are different cross-sectional views showing the relationship between the alignment hole 31 and the vibrated object 40, and FIG. FIGS. 7 and 8 are front views showing other embodiments of the vibrating component alignment device shown in the figure, and FIGS. 7 and 8 show the flow of the vibrated object 40 when the vibrating component alignment device shown in FIG. FIG.

The present invention includes a tilting device 20 fixed to a base frame 50, and a vibration generator l pivotally supported on the base frame 50 via a tilting shaft 21.
0 and a component alignment plate 30 fixed to the vibration generator 10.

The tilting device 20 is attached to the base frame 50! 2 across the oblique shaft 21
It is formed by the sunken shillings 27 and 23.

Furthermore, when the cylinder rod of one cylinder 22 protrudes, the cylinder loft of the other cylinder 23 does not protrude, and conversely, when the cylinder rod of the other cylinder 23 protrudes, the cylinder loft of the other cylinder 23 protrudes. is formed so that the cylinder rod of one cylinder 22 does not protrude, and vibration is generated by the protrusion of the intersection W of both cylinders 22 and 23. It has become.

Further, the vibration generator 10 has a base frame 50 by the tilting shaft 21.
A stationary frame 11 pivotally supported by a stationary frame 11, and a vibrating body 1 connected to the stationary frame 11 by a connecting body 12 having an opening.
3, a motor 14 fixed to this vibrating body 13, and an eccentric body 16 fixed to an output shaft 15 of this motor 14.

Further, the connecting body 12 is made of a flexible material such as a spring, vibration-proof rubber, or the like.

Further, the motor 14 is provided so that the output shaft 15 is parallel to the surface of the vibrating body 13. Therefore, the rotation of the eccentric body 16 due to the rotation of the motor 14 causes the vibration body I3 to vibrate in the vertical direction.

Further, a one-component alignment plate 30 is fixed to the vibrating body 13.

This component alignment dish 30 has a large number of alignment holes 31 recessed as shown in FIG. 40
If this is a screw 41, it is formed to have a slightly larger diameter than the screw 41 to be aligned.

Next, the operation of this vibrating component alignment device will be explained.

First, to explain the state before the start of operation, the vibrating body 1
3 for the illustrated example shown in FIG.

It is tilted in either direction with the tilt axis 21 as the center.

The following description will be made assuming that this direction of inclination is, for example, to the left in FIG.

Further, it is assumed that a large number of screws 41 are contained as objects 40 to be vibrated in the component alignment tray 30 fixed to the vibrating body 13 of the vibrating device.

In this state, the cylinder rod of the right cylinder 23 protrudes in the opposite direction, and the cylinder rod of the left cylinder 22 is retracted.

When the motor 14 is rotated in this state, this motor 14
The eccentric body 16 fixed to the output shaft 15 rotates, and due to the eccentric rotation of this eccentric body 16.

A load is applied to the motor 14 itself to cause it to perform circular motion.

However, at this time, since the motor 14 is fixed to the vibrating body 13, and this vibrating body 13 is fixed to the stationary frame 11 by the connecting body 12 having 0.0 flexibility, the stationary frame 11 is considered to be a stationary axis. At that time, 7-14 yen! I! Due to the load in the opposite direction, the vibrating body 13 becomes 1. due to the nf flexibility of the connecting body 12. It begins to repeat circular motion in the vertical direction.

This minute circular motion in the vertical direction acts on the vibrating body 13 as so-called vertical vibration in the circular direction.

Further, at the same time as the motor 14 is rotated, the cylinder rod of the left cylinder 22 is gradually protruded, and the cylinder rod of the right cylinder 23 is gradually retreated, so that the vibration generator 10 itself is rotated. The left slope gradually shifts to the right #i slope.

Further, even when changing the tilt direction around the tilt axis 21 by alternating the tilt directions, the motor 14 continues to rotate in the vertical direction, so the vibrating body 13
is one that repeats fine longitudinal vibrations.

In this way, the cylinder rod of the cylinder 22 on the left side of Figure 5 protrudes, and eventually the vibrating body 1
3 itself will be tilted to the right about the tilt axis 21.

When longitudinal vibration occurs in the vibrating body 13 in this way, since the component alignment plate 30 is fixed to the vibrating body 13, fine longitudinal vibration also occurs in the component alignment plate 30.

Due to such minute longitudinal vibrations of the component alignment plate 30, the screws as the vibrated objects 40 in the component alignment surface 30 are also vibrated, and the screws 41 become ten dollar state in one component alignment@30.

Then, some of the screws 41 have threaded portions that fit into the alignment holes 31.

In order to prevent the screws 41 whose threaded portions have entered the alignment holes 31 in this way from popping out of the alignment holes 31 due to subsequent vertical vibration, the screws 41 are kept in all the alignment holes 31 by repeating vertical vibration and tilting. This allows the screws 41 to be aligned.

Further, FIG. 5 shows a case in which it is used to align bins 42 formed in a crank shape.

Generally, such a bin 42 has a long axis 43, a crank part 44, and a short axis 45. When aligning, the short axis 4
In many cases, the alignment hole 31 is arranged with the long axis 43 facing upward, as shown in FIG.
Alignment is performed by providing a groove portion continuous with the alignment hole 31 into which the crank portion 44 is inserted in the component alignment plate 30 and applying longitudinal vibration.

If the long sleeve 43 enters the alignment hole 31 during such vibrations, it will not jump out of the alignment hole 31 due to subsequent vibrations, but if the short shaft 45 enters the alignment hole 31,
The subsequent vibration causes the bottles 42 to pop out of the alignment holes 31, so that they can all be aligned in a predetermined shape in the end.

That is, when the bottles 42 are arranged in a predetermined shape in this way, the size is such that when the short axis 45 enters the alignment hole 31, it pops out, but when the long axis 43 enters, it does not pop out. It is necessary to achieve longitudinal vibration of

In the embodiment shown in FIG. 6, the shaft sleeve 15 of the motor 14 is
This figure shows the case where it is tilted with respect to the diaphragm.

With this configuration, the eccentric rotation of the motor 14 causes the diaphragm to vibrate in a mixture of longitudinal and transverse vibrations.

When such vibration occurs, the object 40 to be vibrated is aligned with the alignment hole 31 due to the longitudinal vibration, and the lateral vibration becomes circular vibration, so the object 40 to be vibrated is subjected to fine circular vibrations. , it will gradually move in the left and right direction by the tilting device 20.

If such a movement is to the right, the seventh
As shown in the figure, the objects 40 to be vibrated, which were all gathered to the left of the vibrating body 13 before the movement started, gradually move to the right as the objects 40 are tilted to the right and vibrated. If the lateral vibration of the vibrating body 13 itself is, for example, clockwise rotation as shown in FIG. shall be.

Therefore, at this time, the vibrated object 40 is the seventh
In the figure, it moves in the L direction and also in the right direction.

After moving 17 to the right in this way, the vibrated objects 40 on the vibrating body 13 are gathered to the right of the vibrating body 13, but now they are moving in the opposite direction, that is, to the left. Due to the inclination, as shown in FIG. 8, the vibration body 13 moves to the left side of the vibrating body 13 while gathering toward the front side in the drawing -Lf.

Therefore, according to the embodiment shown in FIG. 6, the vibrated object 40 in the component alignment surface 30 fixed to the vibrating body 13 of the vibrating tilting device 20 is subjected to longitudinal vibration and circular direction vibration due to the rotation of the motor 14. Due to the lateral vibration and the tilting by the tilting device 20, the vibrating body 13F is moved in different directions on the way back and forth in the tilting direction.

Therefore, by repeating rightward inclination and left lv1 inclination by the inclination device 20 while causing the vibrating body 13 to perform horizontal circular vibration, the vibrated object 40 is moved toward the component alignment surface 30.
The particles move in an almost uniform distribution.

Therefore, the one-component alignment plate 30F is moved in an extremely uniform manner, and all the alignment holes 31 are aligned.

Furthermore, in the above theory IJ11, cylinder 22゜23
It will be easier to use if it is equipped with a speed controller and is configured to move forward and backward gradually. Furthermore, it is also possible to attach and retract the cylinder by Ih and repeat the inclination by moving the cylinder forward and backward.

Furthermore, although the tilting device 20 has been described using a cylinder as an example, other methods may be used to form the tilting device 20, such as the tilting device 20 using an eccentric cam.

Furthermore, in the embodiment described above, circular vibration using eccentric rotation of the motor 14 as the vibration generator 10 was explained as an example, but other stages, for example, eccentric rotation by an eccentric cam fixed to the output shaft of the motor, were explained. It is also possible to use a vibration generator 101 that repeatedly converts interlocking into linear interlocking, or a vibration generator 10 that uses repeated linear motion using the retraction of cylinder a due to excitation and demagnetization of a magnet-lenoid.

[Effects of the Invention] As explained above, in the unexploded 1F 1, it is possible to apply vertical vibration to the component alignment mold and to tilt the vibration device itself that performs this vertical vibration. (Finally, a parts alignment mold with many alignment holes for aligning parts is fixed to the vibrating device, and the vibration in the vertical direction produces a screw with a thin diameter or a vertically long and directional part such as a bottle. By forming the parts so as to be aligned with the alignment holes of the parts arrangement tray, the parts can be arranged efficiently in an extremely short time.
