In the figure, 8 is a rail for the moving frame 2, and the rail 8 is laid on the floor.

  And an example of the ventilation path (blower means) of the air blower 3 and the top nozzle 5 is demonstrated. In this example, left and right pairs are connected to a flexible first pipe 10 (which is an air pipe or a duct, etc., which is the same) connected to the outlet 3a of the blower 3 in left and right pairs (an example). A left and right pair (an example) of a substantially L-shaped (an example) second pipe 11 mounted on a lifting / lowering rod 15 (an example) is connected. The second pipe 11 is connected to the left and right side surfaces 50 a of the casing 50 of the top nozzle 5. Further, the lower surface 50b of the top nozzle 5 has an outlet 16 for exhausting high-pressure air. The elevating rod 15 is provided on the leg 2a of the moving frame 2 so as to be movable up and down. In this example, the sprockets 18 and 18 provided on the moving frame 2 and a medium such as a chain suspended between the sprockets 18 and 18 are provided. 19 and a motor (not shown) for driving the sprocket 18 are moved (lifted and lowered). In the figure, reference numeral 22 denotes a guide rail, and 23 denotes a trochanter provided on the lifting rod 15.

The lift rod 15 is also at a high position. In this state, the second pipe 11 is at a high position, and the first pipe 10 is compressed. However, in this example, there is no restriction by the upper surface 50c of the top nozzle 5 and the lower surface of the moving frame 2 as in the prior art, so that the first pipe 10 is not overcompressed or noise generation due to expansion and contraction is avoided. It can be useful, and can be useful for energy loss. Although not shown, normally, when the moving frame 2 is moved and the sensor 24 is activated, the position of the top nozzle 5 is low (for example, at the rear side), which is substantially the same as the imaginary line state in FIG. As described above. In addition, although the 1st piping 10 expands and contracts because the top nozzle 5 is raised and lowered, this 1st piping 10 is the structure which can endure this, and has the function. In addition, it is intended to effectively withstand this expansion and contraction, to eliminate noise generated by the first pipe 10, and to reduce energy loss, etc., via a spring 30 (supporting means) as shown in FIG. It is a structure that is suspended and provided with a bending allowance 10a, and can be formed into a substantially inverted S shape when viewed from the front.

  The air blowing according to the present invention is the same as the conventional one, and the blower outlet 3a of the blower 3 → the first pipe 10 → the lift 15 (in some cases) → the second pipe 11 → the outlet 16 of the top nozzle 5 → the vehicle. Via route A. The wind flow is indicated by arrows.

  In the example of FIG. 4, the connecting rod 25 is omitted, a part of the fourth pipe 28 replacing the second pipe 11 is formed with rigidity, and the top nozzle 5 is mounted on the fourth pipe 28. It is. As a result, the number of parts and / or costs can be reduced, the weight can be reduced, and the running cost can be reduced. A cable 26 is provided in the fourth pipe 28. It is a requirement that a part of the fourth pipe 28 is at least between the top nozzle 5 and the lifting rod 15 and that the top nozzle 5 can be mounted.

  5-8 is each figure explaining the other structure of the top nozzle 5 and the 2nd piping 11, and each example which penetrates the 2nd piping 11 in the top nozzle 5 is shown, This example Then, the blower outlet 110 is opened on the upper surface 11a of the second pipe 11, the high-pressure air is blown out toward the upper side 50d of the top nozzle 5, and the air is blown along the substantially side surface of the inner surface 50d. The elimination and rectification effect can be expected. It is also effective for uniforming the wind speed distribution. The good wind flow in this figure is indicated by arrows. Other configurations of the second pipe 11 are in accordance with the above-described example. 7 and 8 are examples in which the air outlet 16 of the top nozzle 5 is changed, and is an example in which a change is given to the wind flow.
