Abstract

PURPOSE:To make brake the main body of a conveyor simply and securely when necessary, by furnishing an air circulation control device to convert air flow to direct supply, reverse supply, and cut off to and from an air passage in a main body, between the beginning of the air passage and an air supply source. CONSTITUTION:When power is supplied to the solenoid 8C of an air circulation control device 8, the air from an air supply source passes through a hose 6 and an air passage 2 inside a main body 1, on which cargoes 5 are loaded, and spouts from injection pipes 3, to float the main body 1. Therefore, the main body 1 can be carried easily to the desired direction by a small power such as a man power for example. On the other hand, if power supply is cut off to a solenoid 8C, a spring 8D acts to push a plug 8A to close the hose 6, the air 4 in the injection pipes 3 escapes to the lower back pressure direction, and the main body 1 is braked securely by the friction between a floor 7 and the ends of the air injection pipes.

することができる。Function> Since the air levitation transportation device of the present invention is configured as described above, when the air flow control means is switched to the feeding state, air is fed from the air supply source to the air passage in the main body, and air is ejected. High-pressure air is ejected from the tube to levitate the main body, and by applying a moving force, the main body can be easily transported with the load on it.

動するようになる。Additionally, when applying braking, if the air flow control means is switched to the air cutoff state, the air accumulated in the air nozzle escapes to a direction with lower back pressure, and the air no longer floats, and the main body is connected to the floor and the air nozzle. The brake is applied due to the frictional force on the end surface, resulting in braking.
