As shown in FIG. 3, a pair of air outlets 128 are provided on the side surface portion 32 of the cylindrical body 18 so as to be rotationally symmetric with respect to the center line of the rotation shaft 50. The air outlet 128 constitutes a pressurized air supply means together with a pressurized air supply source and piping (not shown).

  An appropriate shallow recess 78 is provided on the lower surface of the flange 72 of the rotary shaft 50, and an O-ring 80 is mounted. A cleaning nozzle member 84 that injects the cleaning liquid toward the center of the inner space 20 of the cylindrical body 18 is attached to the lower surface of the flange 72 with mounting bolts 86.

  The cleaning nozzle member 84 includes a mounting portion 88 attached to the flange 72, a cleaning arm 82 connected to an end portion of the mounting portion 88, and a central cleaning portion 104 provided below the central portion of the mounting portion 88. . Inside the attachment portion 88, cleaning liquid distribution pipes 90 are formed in four directions perpendicular to the introduction hole 54 of the rotating shaft 50. A cleaning arm 82 is connected to the ends of the pair of distribution pipes 90, and is connected to a hollow cleaning pipe 94 in the cleaning arm 82. The cleaning arm 82 is provided with an injection nozzle 92 that communicates with the cleaning pipe 94 toward the center of the cylindrical body 18. The spray nozzle 92 of the cleaning arm 82 is determined according to the length of the cleaning arm 82 and the state of the article 12 to be cleaned. The other pair of distribution pipes 90 of the attachment portion 88 are closed. Further, a lid 100 is attached to the end of the cleaning arm 82 with a mounting bolt 102 with a sealing material 98 interposed therebetween, and is closed.

  The central cleaning portion 104 provided on the extension of the rotation shaft 50 at the center of the attachment portion 88 is formed in a columnar shape, and is attached to the attachment portion 88 with an attachment bolt 108 by a flange 106 portion at one side end.

A lid 112 sandwiches the sealing material 114 at the end of the cleaning pipe 110. It is fitted with. An appropriate recess 116 is provided around the end of the cleaning pipe line 110 where the central cleaning part 104 abuts the attachment part 88, and an O-ring 118 is attached to connect the pipe line in a liquid-tight manner.

Next, operation | movement of this washing | cleaning apparatus 10 is demonstrated. First, the object 12 to be cleaned is fixed to the fixture 14 of the base part 16, and the cylindrical body 18 is put in close contact with the base part 16 so as to cover the object 12 to be cleaned by a device (not shown). Further, a rotary joint of a cleaning pipe (not shown) is attached in close contact with the connecting portion 60 of the cylindrical body 18 and the introduction hole 54 of the rotating shaft 50. Further, a pressurized air hose (not shown) is connected to the air outlet 128 of the side surface portion 32 of the cylindrical body 18, and pressurized air is sent from a supply pump (not shown). As a result, the pressurized air blown out from the outlet 128 efficiently hits the teeth 126 of the rotating body 120 through a narrow space surrounded by the inner surface of the cylindrical body 18 , and the rotating body 120 is approximately 60 to 120 rpm. Rotate in one direction. At this time, the cleaning nozzle member 84 attached to the rotating body 120 also rotates together. Then, the cleaning liquid is fed into the introduction hole 54 of the rotating shaft 50 from a cleaning pipe (not shown) by a supply pump (not shown). This cleaning liquid passes through the distribution pipe line 90 of the attachment portion 88, is guided to the cleaning pipe line 94 of the cleaning arm 82, and is also guided to the cleaning pipe line 110 of the central cleaning unit 104. The guided cleaning liquid is sprayed from the spray nozzles 92 provided in the cleaning arm 82 and the central cleaning unit 104 toward the object 12 to be cleaned. At this time, the cleaning liquid is also sprayed from the spray nozzle 92 provided in the attachment portion 88 toward the object to be cleaned 12 into the cylinder.

  Next, after spraying the cleaning liquid for a predetermined period, the cleaning liquid piping is switched to a supply source of drying air. Thereby, drying air is sent into the introduction hole 54 of the rotating shaft 50 from a cleaning pipe (not shown). The supplied air passes through the distribution pipe line 90 of the attachment portion 88 and is led 94 to the cleaning liquid pipe of the cleaning arm 82. As in the case of the cleaning liquid, the drying air is sprayed from the jet nozzle 92 provided in the cleaning arm 82 into the internal space 20 of the cylindrical body 18 so as to blow the air to be cleaned 12. At this time, the air for drying is also jetted from the jet nozzle 92 provided in the attachment portion 88 toward the article to be cleaned 12 in the internal space 20 of the cylindrical body 18 as in the case of the cleaning liquid. Further, in the cylinder 18, the cleaning liquid sprayed onto the article to be cleaned 12, the drying air, and the air blown onto the rotating body are discharged from the discharge hole 46 of the base portion 16.

According to the cleaning apparatus 10 of this embodiment, the cleaning of the article 12 to be cleaned is performed in the small cylinder 18 as much as possible within the range in which the cleaning nozzle member 84 can rotate. Less is. Further, since the cleaning nozzle member 84 performs cleaning while rotating around the object 12 to be cleaned, even the object 12 having a complicated shape can be cleaned evenly. Further, since compressed air is used for the rotational power of the cleaning nozzle member 84, it is not necessary to use a motor or the like, the structure is simple, the apparatus itself is miniaturized, and many objects to be cleaned 12 are saved without taking up space. It can be washed.

In addition, the rotary body of this invention should just be a gear shape in a side surface, and can be suitably set to the shape which can receive and rotate with compressed air. In addition, the cleaning nozzle of the cleaning device of the present invention is not limited to the above embodiment, and the central cleaning unit may be removed and used in accordance with the shape of the object to be cleaned. A member may be used. At this time, after removing the central cleaning section, the opening of the distribution pipe path of the cleaning nozzle connected to the cleaning liquid pipe of the central cleaning section is closed with a lid or the like.

  In the cleaning device of the present invention, the strength of the compressed air blown to the rotating body can be set as appropriate. The drive source sprayed on the rotating body may be a liquid such as water as well as compressed air, and can be selected as appropriate. Moreover, the number of blower outlets can be set suitably. Furthermore, in the cleaning apparatus of the present invention, the type of the object to be cleaned and the shape of the cylinder can be set as appropriate, and the cleaning liquid can be an appropriate one such as a detergent or an organic solvent.
