管２５内の切換弁２６が空気の圧力によって上昇する。When air is fed under pressure by an air pressure feeding device (not shown), the switching valve 26 in the branch pipe 25 is raised by the pressure of the air.

側２５ｂよシ回転方向にずれるものである。The communication hole 29 is aligned with the one side 25a. Therefore, air is forced into the air motor 2 through the vibro, rotates the rotary blades 2b, and rotates the rotary shaft 3. As the rotating shaft 3 rotates, the gear 4 fixed to the tip thereof and the gear 14 meshing therewith also rotate, and the cylindrical shaft 11 rotates. As the cylindrical shaft 11 rotates, a polishing hammer 20 is projected outward by centrifugal force and polishes the inner surface of the tube. The projecting length of the polishing hammer 20 needs to be changed appropriately depending on the diameter of the tube, and this adjustment is done by adjusting the amount of air to be pumped and adjusting the rotational force. When the polishing is completed and the air pumping is stopped, the polishing nozzle 20 is retracted to its original position by the action of the spiral spring 18, and at the same time, the switching valve 26 also expands the pressure of the coil spring 31. The affiliated forces will descend. At this time, the switching valve 26 rotates 1/4 turn. Then, when air is pumped again, the switching valve 26 rises again. At this time, it is further rotated by 1/4 so that the communication hole 29 coincides with the other side 25b. Therefore, air passes through the pipe 7 and blows out from its upper end, and the paint in the paint tank 35 is blown out from the tip of the nozzle 36. At the same time, turbo fan 2
2 also rotates, and the paint and air are blown out in the form of mist from between the rotating blades 24 through the air introduction pipe 21 and sprayed onto the painted surface. Note that during painting, only the air introduction pipe 21 rotates, and the cylindrical shaft 11 and gear 14 do not rotate. When the air pressure is stopped after the painting is completed, the rotation of the turbo fan 240 is also stopped, and at the same time, the switching valve 26 is also lowered. At this time, it rotates by 1/4 again, and the communication hole 29 is shifted from the other side 25b in the direction of rotation.
そして、管を交換した後再び空気を圧送すれば前記と同
手順によって順次管内面の研磨と塗装を行うことができ
るものである。Then, after replacing the tube, by pumping air again, the inner surface of the tube can be sequentially polished and painted by the same procedure as described above.
本発明は上記の如き構成作用であるから、一台の装置で
もって而も連続して自動的に管内面の研磨と塗装を行う
ことができるものである。また装置全体が小型であシ且
つ重量も左程ないから持ち運びにも便利であシ、加えて
操作も簡単である等実用上極めて便利なものである。Since the present invention has the above-described structure and operation, it is possible to continuously and automatically polish and paint the inner surface of a tube with a single device. In addition, the entire device is small and light in weight, making it convenient to carry, and in addition, it is easy to operate, making it very convenient in practice.
