[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air discharge nozzle for air blow drying of a work. More specifically, the air blow drying for drying the work after cleaning the work such as precision machine parts and electronic machine parts by ultrasonic cleaning or the like. The present invention relates to an air discharge nozzle of an apparatus.

[0002]

[Prior art]

 As is well known, workpieces such as precision machine parts and electronic machine parts are cleaned by ultrasonic cleaning and other cleaning methods after processing, and after cleaning, the surface and the inside of the workpiece are dried. By the way, one of the drying methods for drying the work is air blow drying. This is a method in which the air discharge nozzle is directed toward the work, and the air created by a compressor or the like is discharged from there to remove the water droplets on the work and dry it.

Looking at the prior art of the air discharge nozzle, there is a cylindrical air discharge nozzle connected to the compressor via an air tube, and air is directly sent from the compressor into the cylindrical air discharge nozzle. The air was directly discharged from the discharge port of the air discharge nozzle. Here, the air discharge nozzle does not blow air to the work in a fixed state, but blows air while moving along the work. Thus, the conventional cylindrical air discharge nozzle is of a single-layer type, and the discharge port can be set at a predetermined position and the air discharge direction can be set only in the predetermined direction.

[0004]

[Problems to be solved by the device]

 According to the above-mentioned conventional technique, since the air ejection nozzle ejects air while moving along the work, it is possible to perform drying along the work.

However, although the air discharge nozzle discharges air while moving along the work, the position of the discharge port of the air discharge nozzle is fixed, and the air discharge direction is fixed. Therefore, depending on the shape of the work. There was a problem that some of them were difficult to dry completely, and some of them could not be dried. Further, since the air ejection direction is constant, it may be necessary to change the surface of the work to which the air is sprayed while drying.

[0006]

[The purpose of the device]

 Therefore, the object of the present invention is to allow the air discharge nozzle to move along the workpiece and also to direct the discharge port of the air discharge nozzle in various directions, which makes it easy to handle workpieces of various shapes. However, it is to provide an air discharge nozzle that does not depend on the position where the work is placed.

[0007]

[Means for solving the problem]

 In order to achieve the above object, the present invention has the following technical means. That is, the present invention will be described with reference to the reference numerals in the accompanying drawings corresponding to the embodiments. According to the present invention, the air pressure generated by the compressor is introduced into the tubular nozzle to penetrate the tubular nozzle in and out. In the nozzle of the device that blows air from the discharge port onto the work to dry it, the cylindrical nozzle 2 is formed as an inner and outer double, and the air generated by the compressor is introduced into the inner pipe 5 The pipe 5 has an opening 6 formed therein, and the outlet pipe 4 is provided at an arbitrary position of the outer pipe 3 which is closed so as to wrap the inner pipe 5. The air flowing out from the opening 6 of the pipe 5 inside the discharge port 4 is discharged, and the outer pipe 3 is rotatable with respect to the inner pipe 5. Air discharge in air blow drying of work The nozzle 2.

[0008]

[Action]

 According to the above configuration, the outer pipe 3 is rotatable with respect to the inner pipe 5, and therefore the angle of air blow can be changed, so that the surface of the work 1 is inclined or complicated. The angle of the air blow can be changed according to the work 1 even if it is moved.

[0009]

【Example】

 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the air discharge nozzle 2 of this embodiment has a cylindrical nozzle to which an air tube 8 is connected.

As shown in FIG. 2, the air discharge nozzle 2 is formed in double inside and outside, and an air tube 8 connected to a compressor (not shown) is connected to both ends of a pipe 5 inside the air discharge nozzle 2. ing. An outer pipe 3 is installed so as to enclose the inner pipe 5, and a rotating means 7 is attached so that the outer pipe 3 rotates with respect to the inner pipe 5.

As shown in FIG. 3, the inner tube 5 is provided with a plurality of openings 6 along the longitudinal direction, and the outer tube 3 is provided with a discharge port 4 in the longitudinal direction at an arbitrary position. There are several along the line. In this embodiment, the inner pipe 5 is cylindrical and four openings 6 are provided at every 90 degrees, and the outer pipe 3 is square tubular and the discharge port 4 is provided at the corner. An example is shown.

Next, a method of drying the work 1 using the air discharge nozzle 2 will be described. First, air pressure is generated by the compressor, and the air is introduced into the pipe 5 inside the air discharge nozzle 2 via the air tube 8. This air is successively introduced into the inner pipe 5, so that the air flows from inside the inner pipe 5 through the opening 6 to between the inner pipe 5 and the outer pipe 3 and then to the outer pipe 3. It is discharged from the discharge port 4.

Further, while ejecting air from the air ejection nozzle 2, the entire air ejection nozzle 2 moves along the work 1 to dry the work, as shown by an arrow A in FIG. The position of the outer tube 3 is changed by the rotating means 7 according to the shape of the work 1 to change the air discharge direction. For example, when the work 1 cannot be placed below the air discharge nozzle 2, the work 1 is placed above the air discharge nozzle 2, the outer pipe 3 is rotated 180 degrees, and the discharge port 4 is directed upward. It can be dried in that state.

As described above, since the air discharge nozzle 2 is formed in the inner and outer double layers, and the outer pipe 3 is rotatable with respect to the inner pipe 5, the shape and arrangement state of the work 1 are determined. The direction of air ejection can be changed according to the above conditions, which makes it easier to dry.

Further, although the air sent from the compressor may be pulsating, it passes through the opening 6 of the inner pipe 5, is introduced into the outer pipe 3, and is then discharged, so that The pulsating air is rectified, and the air is uniformly discharged to allow uniform drying.

In the present embodiment, the outer tube 3 is assumed to have a square tubular shape and the discharge port 4 is provided at the corner, but the operability is good, and the surface of the work and the moisture inside are wiped out and dried. Various shapes of pipes are conceivable as long as the possible air can be discharged.

[0017]

[Effect of device]

 As described above in detail, according to the present invention, since the cylindrical air discharge nozzle is double inside and outside, and the outer pipe is rotatable with respect to the inner pipe, the shape and arrangement position of the workpiece can be improved. It has the advantage that it can be handled and it becomes easier to dry. Further, since the inner and outer layers are formed, there is an advantage that it is easy to prevent the pulsating flow of air and to easily eject the air uniformly, and thus it is easier to uniformly dry the work and further prevent the deterioration of quality.
