Description

[Detailed Description of the Invention] The present invention is an alignment device for cylindrical parts having notched grooves, and more specifically, a cylindrical part having a notched groove on the outer peripheral surface or a cylindrical part having a notched groove in a certain direction. This invention relates to an alignment device that aligns the objects so that they are aligned.

Column-shaped parts having a simple circular cross-sectional shape can be easily aligned in the direction of their central axis so that they are aligned with the outer peripheral surface, and sent to the next process using a well-known pole feeder or the like.

However, for example, if a cylindrical part 1 having a notch groove 2 in the central axis direction on the outer peripheral surface as shown in FIG.
As shown in the figure, it is not easy to align the notch grooves 2 in a certain position and send them out in a uniform manner in the direction of the central axis.

In such cases, conventionally, the above-mentioned cylindrical part, which has been sent out with its outer circumferential surface aligned by a pole feeder, etc., is guided into a rotating device that forcibly rotates the part, and the part is rotated and installed in the same device. The cylindrical part is pressed against the outer circumferential surface of the cylindrical part, and when it faces the notch groove, the part is stopped from rotating and positioned by an engaging piece that is fitted into the notched groove. This was then picked up by a component transfer device in a separate unit and sent to the next process, an extremely cumbersome method.

However, this method requires a special rotation device and transfer device, resulting in a very complicated structure, and during the operation of forcibly rotating the cylindrical component, pressure is applied to the outer peripheral surface of the cylindrical component. The engaging pieces tend to damage the outer peripheral surfaces of the parts, and since each part requires one rotation, it takes a long time to complete the work.

In view of the above points, the purpose of the present invention is to provide a component delivery port of a pole feeder that feeds out a large number of cylindrical components having notched grooves in a row in the direction of their central axis, which fits into the notched grooves of the cylindrical components. Alignment pipes having protrusions are connected, vibrations are applied to the pipes in the tube axis direction and in a direction perpendicular to this, and these vibrations rotate the cylindrical parts fed into the alignment pipes. To provide an extremely convenient aligning device for cylindrical parts having notched grooves, which aligns and sends out the cylindrical parts so that the notched grooves of the parts are automatically aligned in a certain direction by advancing the parts. .

According to the present invention, the structure of the alignment device is extremely simple;
Since the parts are automatically sent out in alignment with their notch grooves aligned, the work time is greatly shortened, and the above-mentioned drawbacks such as the tendency for sun to form on the outer surface can be completely eliminated. .

Hereinafter, the present invention will be explained based on the illustrated embodiments.

FIG. 2 is a plan view of an alignment device for cylindrical parts having notched grooves showing an embodiment of the present invention, FIG. 3 is a side view thereof, and FIG. 4 is a line A--A in FIG. FIG. 3 is a cross-sectional view of main parts taken along line A.

The alignment device 3 of the present invention is a well-known pole feeder 4 that feeds out a large number of cylindrical parts 1 in a line in the direction of their central axis.
a parts alignment pipe 5 connected to the parts delivery port 4a;
A forward excitation device 7 that supports this pipe 5 and vibrates the same pipe 5 in a direction having a certain angle with the pipe axis direction of the pipe 5 is disposed close to the side surface of the pipe 5, and The main part thereof is a rotational excitation device 8 that applies vibration to the eccentric position of the pipe 5 from the side surface of the pipe 5.

The above-mentioned pole feeder 4 is of a well-known type, and when the cylindrical part 1 is fed through the upper opening formed in the shape of a hopper,
As shown in FIG. 2, these parts 1 are arranged in the direction of their central axes and sent out to the delivery port 4a.

The component alignment pipe 5 is formed of a cylindrical pipe, and its front end opening 5a is connected to the component delivery port 4a of the pole feeder 4.As shown in FIG. From the middle to the rear end opening 5b, there is provided a positioning protrusion 9 in the tube axis direction into which the cutout groove 2 of the cylindrical component 1 fits.

The rear end opening 5b serves as a component delivery port through which cylindrical components aligned with the notch grooves 2 aligned are delivered.

This component alignment pipe 5 is supported by a support stand 11, which is an excitation stand, via bearings 10a and 10b.

The support base 11, which is the excitation base, transmits vibrations from the forward excitation device 7 through the elastic plate 6, which is a vibration transmission plate, and the vibration is transmitted to the pipe 5 due to the pipe axis of the pipe. Vibration in the direction of arrow a having a certain angle is applied.

The support table 11, which is the excitation table, and the excitation device 7, which vibrates it via the elastic plate 6, are the same as those of the well-known linear feeder, and the driving source is an electromagnet, which is connected to a commercial frequency. A pulsating flow is applied to vibrate the elastic plate 6 obliquely back and forth.

As shown in FIG. 4, a rotational excitation device 8 that applies vibrations in the rotating direction to the pipe 5 is disposed close to the side of the pipe 5, and transmits vibrations generated by an electromagnet that is a vibration source. The tip of the vibration transmitting member 12 is configured to alternately push positions on both side surfaces of the outer peripheral surface of the pipe 5 that are eccentric with respect to the axis of the pipe.

Therefore, the vibrations generated by the rotational excitation device 8 are transmitted in the direction indicated by the arrow in the figure, so that the pipe 5 reciprocates about its central axis 9.

In addition to the electromagnetic force described above, the vibration sources of the excitation devices 7 and 8 include a motor and an eccentric cam plate, and the vibration period and amplitude can be adjusted as appropriate.

The forward action in which the cylindrical component 1 inside the pipe 5 moves forward in the pipe due to the vibration of the support base 11 by the forward excitation device 7 is similar to the operation of a linear feeder and is well known. , the explanation thereof will be omitted.

Next, in cooperation with the forward movement, the rotational excitation device 8
The operation of rotating the cylindrical part 1 while it is moving forward will be explained below.

As shown in FIG. 6A, the pipe 5 is connected to the forward excitation device 7.
When the part 1 is suspended in the air, the vibration transmitting member 12 of the rotational excitation device 8 is applied to the side of the pipe 5 by the arrow C.
When vibration is applied in this direction, only the pipe 5 rotates slightly clockwise, and the cylindrical part 1 does not rotate.

Next, as shown in FIG. 6B, when the component 1 descends due to its own weight and comes into contact with the inner peripheral surface of the pipe, the arrow C
Since the vibration in the direction is in the opposite direction of arrow d, the pipe 5 rotates counterclockwise.

Accordingly, due to the friction with the inner circumferential surface of the pipe 5, the component 1 also rotates in the direction of arrow e, that is, in the counterclockwise direction.

By repeating such operations, the component 1 inside the pipe 5 rotates continuously only in the direction of arrow e, that is, in one direction.

In this case, in order to rotate the cylindrical part 1 smoothly, it is necessary to appropriately adjust the period and amplitude of the vibrations applied to the pipe 5 by the two excitation devices 7.8.

Next, the effect of aligning the cylindrical parts 1 within the pipe 5 will be explained.

Since the vibration of the pipe 5 caused by the two excitation devices 7 and 8 is a small-period amplitude vibration, the advancement and rotation of the component 1 within the pipe 5 is extremely slow, so that it moves forward while rotating naturally. It is done smoothly.

Therefore, as shown in FIG. 5, the cylindrical component 1 fed from the component delivery port 4a of the pole feeder 4 to the front end opening 5a of the pipe 5 rotates smoothly inside the pipe 5 while passing through the rear end opening. Move forward towards 5b.

The part 1 extends from the middle of the pipe 5 to the rear end opening 5.
The part 1 comes into contact with the inner end of the positioning protrusion 9 provided over the part 1, and the forward movement is temporarily blocked, but since the part 1 is rotating, the notch groove 2 of the part 1 will soon be 6th
As shown in FIG. That is, it is sent out to the next process from the outlet of the rear end opening 5b with the cutout groove 2 facing in a certain direction.

In this way, the rotation of the cylindrical part 10 within the pipe 5 and the forward movement are performed smoothly as described above.

Therefore, according to the device of the present invention, the alignment work time is greatly reduced compared to the conventional means, and since the above-mentioned parts 1 can be rotated easily, there is no risk of damage caused by touching other parts or the pipe 5. There is no fear of doing so.

Furthermore, the cylindrical parts 1 sent out from the rear end opening 5b of the pipe 5 are sent out continuously with their notched grooves 2 aligned in a certain direction, so they can be sent as they are to the next process. This allows the work process to be significantly shortened.

As explained above, according to the present invention, the excitation devices 7 and 8
This cylindrical part with notched grooves has a simple structure in which vibration is applied to the pipe for aligning the parts, and it solves the drawbacks of the conventional alignment means mentioned above, and greatly improves work efficiency. An alignment device can be provided.

In the above embodiment, the cylindrical parts 1 are aligned while being advanced in the horizontal direction, but the parts 1 can also be sent in the vertical direction.

In this case, the cylindrical part will descend due to its own weight, so
The linear feeder mechanism including the forward excitation device 7 becomes unnecessary, and it is sufficient to stand the pipe 5 upright and use only the rotation excitation device 8.

Further, in this embodiment, a solid circular mound-shaped component is used as the columnar component, but it goes without saying that this may be a cylindrical component.
