Hereinafter, the operation of the conveyance system of the present invention having the above configuration will be explained. First, the vehicle 3 is slidably engaged with the pneumatic pipe 1 by means of the wheels 22 . Permanent magnet of pneumatic head 2 141.14□
The magnetic flux emitted from the N pole of the yoke 15 enters the yoke 19 of the traveling vehicle, enters through the 5ffl of the permanent magnets 18□ and 18□ of the traveling vehicle, passes through their interiors, exits from the N pole, and is transferred to the yoke 20 and the pneumatic sender. It returns via the yoke 15 to the S pole of the permanent magnet 14.14.

That is, a closed magnetic path is formed by the permanent magnet and yoke of the air sender 2, and the permanent magnet and yoke of the traveling vehicle.

Therefore, the traveling vehicle 3 is always positioned below the air balloon 2.

Here, for example, open the electric valves 71 and 82, and open the electric valve 8□.
, 72 and start the compressor 9, the air pump 2
Air pressure from the compressor 9□ is applied to the pneumatic tube 1, and the pneumatic tube 2 is propelled toward the end where the electric valve 72.8□ is provided. The traveling vehicle 3 moves the pneumatic tube 2 along the pneumatic pipe 1.
Run with. Conversely, if the electric valves 7□ and 81 are opened and the electric valves 7□ and 8□ are closed, the vehicle 3 will travel in the opposite direction.

Therefore, the pneumatic pipe 1 has a plurality of magnetic sensors 101 to 10.
Tl is provided. These magnetic sensors detect the magnetism of the permanent magnet when the pneumatic sender 2 passes, and inform the position of the pneumatic sender 2. The output is input to the controller 11 and is used as data for controlling running and stopping of the traveling vehicle 3.

For example, from the terminal with compressor 9□ of pneumatic pipe 1,
To move the traveling vehicle 3 to the position where the magnetic sensor 101 is provided, the following procedure is performed.

First, the electric valve 81.7□ is closed and the electric valve 71.8□ is opened. Then, as described above, the pneumatic carrier 2 and the traveling vehicle 3 are propelled along the pneumatic pipe 1 in the direction of the magnetic sensor 101.

When the air balloon 2 and the traveling vehicle 3 reach the position of the magnetic sensor 10□, the magnetic sensor 10□ detects this and generates an output. When the above output is input, the controller 11 closes the electric valve 7□ and opens the electric valve 7□. As a result, air pressure from the compressor 9□ of the pneumatic sender 2 is applied, and a brake is applied to the pneumatic sender 2, causing the pneumatic sender 2 to decelerate and come to a stop. When the traveling vehicle 3 stops at the position of the magnetic sensor lO1, the electric valve 72 is closed.

As described above, in the conveyance system of the present invention, by inputting the number etc. of the magnetic sensor for which the traveling vehicle 3 is to be stopped into the controller 11 and starting the system, the traveling vehicle 3 automatically travels to that position. and will be stopped.
