Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for mechanically stirring a developer for penetrant testing in an aerosol can used for non-destructive testing, for example.

Conventionally, aerosol cans of this type that require stirring have been manually stirred by workers on site each time they are used, but stirring must be continued for a certain period of time in order to achieve uniform stirring.

Therefore, during agitation, workers are tied up, which reduces work efficiency, and the degree of agitation may vary depending on individual differences among workers. In the case of a developer for penetrant flaw detection, it was not possible to spray a homogeneous developer, which adversely affected the inspection results.

The present invention has been made based on the above-mentioned circumstances, and an object thereof is to provide an agitator for aerosol cans that can stir the aerosol cans without the need for manual labor before use, and that can stir the aerosol cans uniformly.

The present invention will be described below based on an illustrated embodiment.

In the figure, reference numeral 1 denotes the main body of the stirring device, and the main body 1 is provided with a rotational drive mechanism 2, and the rotational drive mechanism 2 is constructed as follows.

That is, 3 is a motor whose rotation speed can be adjusted, and a drive gear 4 is attached to the output shaft of this motor 3, and this drive gear 4 is meshed with a driven gear 6 fixed to a rotating shaft 5. .

The rotary shaft 5 is supported in the main body 1 via bearings 7.8.

A sun gear 10 of a planetary gear mechanism 9 is attached to the rotating shaft 5.
is attached.

The planetary gear mechanism 9 includes the sun gear 10, a plurality of planetary gears 11, for example, 2 to 8 planetary gears 11, which rotate around the sun gear 10 in a vertical plane, and each planetary gear 1.
1, and an annular internal gear 12 that meshes with the main body 1. This internal gear 12 is fixed to the main body 1.

Further, each of the planetary gears 11 is rotatably mounted on a planetary gear mounting base 13 that can freely rotate with respect to the rotating shaft 5.

14 is a rotation bearing of the planetary gear mounting base 13.

A holder 15 for detachably holding an aerosol can A is attached to each planetary gear 11.

Each holder 15 is attached obliquely to the rotating shaft 5 at an angle of, for example, 30° to 50° in a direction perpendicular to the rotating shaft 5 .

Further, as shown in FIG. 3, an elastic holding member 16 made of an elastic material such as rubber is attached to the inner surface of each can holder 15.
By inserting the elastic holding member 16, the aerosol can A is easily and reliably held by the elastic force of the elastic holding member 16.

Note that the aerosol can A that requires such stirring generally contains a pole for promoting stirring.

The agitating device for an aerosol can configured as described above is used, for example, when agitating developer material contained in an aerosol can in non-destructive testing by penetrant testing.

The operation of this stirring device will be explained below.

First, the can holder 15 is made to hold the aerosol can A containing the penetrant developing material.

Then, turn on the power, rotate the motor 3, and drive the drive gear 4.
When the rotating shaft 5 is rotated via the driven gear 6, the sun gear 10 rotates together with the rotating shaft 5.

Then, the planetary gears 11... rotate on their own axis following the sun gear 10, but since these planetary gears 11... mesh with the internal gear 12, each planetary gear 11... rotates on its own axis and rotates on its own axis. revolves around.

That is, since the aerosol can A is held obliquely with respect to the planetary gear 11, it performs a so-called conical swinging motion and rotates on its own axis, while revolving around the sun gear 10 in a vertical plane. .

Therefore, the attitude of the can A changes one after another, and the developer inside the can moves violently from side to side, up and down, and is stirred.

In this way, according to the device of this embodiment, the developer in the aerosol can A moves violently within the can and is sufficiently agitated, and the agitation promoting pole in the aerosol can A moves due to its own weight. Since it moves to every corner inside the can, it can effectively stir the inside of the can.

Since the aerosol can A can be stirred without manual intervention, the worker is not restricted to stirring the aerosol can A during non-destructive testing and can perform other tasks.

Therefore, inspection work can be carried out efficiently, and
Stirring can be performed uniformly regardless of individual differences among workers.

Therefore, since homogeneous developer can be sprayed, the reliability of inspection is improved.

Moreover, since a large number of aerosol cans can be stirred at the same time depending on the number of can holders 15..., when a large number of aerosol cans A are required, they can be mixed efficiently and inspection work can be carried out quickly. be able to.

Note that if it is necessary to adjust the stirring rotational speed due to differences in the viscosity or other physical properties of the developer in can A, the motor 3
The rotation speed may be adjusted as appropriate.

Although the present embodiment is constructed as described above, various modifications can be made in carrying out the present invention as long as they do not go against the gist of the present invention.

Further, the vertical plane on which the aerosol can rotates does not necessarily have to be exactly vertical, but may be inclined to an extent that does not impair the stirring action.

Furthermore, the present invention is applicable not only to developers but also to paints and other aerosol cans that require stirring.

As explained above, according to the present invention, an aerosol can is held in a direction perpendicular to the rotation axis direction of the planetary gears by a plurality of planetary gears that revolve around the sun gear and rotate on its own axis as the sun gear rotates. Since the can holder is designed to rotate in a substantially vertical plane to automatically stir the contents of the aerosol can, the aerosol can can be sufficiently and uniformly stirred without manual intervention prior to use. .

Therefore, since a homogeneous content can be sprayed, for example, when used for stirring a developer in a non-destructive test using penetrant testing, a homogeneous developer can be sprayed and the reliability of the test results is improved.
