An endless belt rotates between a tail pulley and a head pulley. The belt is floated on a tubular belt bracket by blowing air out of the air blowing holes of the belt bracket, and extends from the tail pulley to the head pulley. An ultra high molecular weight polyethylene layer is applied over the inner circumferential surface of the belt support, opposite the belt, thus ensuring smooth operation of the belt.
The present invention relates to an airborne belt conveyor device in which a belt is partially floated on a running belt holder by blowing air out of the air outlets of the belt holder. JP-A-7-206122 discloses a belt conveyor device with internal and external coaxial tubes, an arc path of an endless flexible belt that is wound between a pair of pulleys passing through an inner tube, Between The outer and inner tubes, the running resistance of the belt being reduced when the belt is floated by air which is blown out of the air outlets which are formed at regular intervals in the lower part of the tubes.
There is a conveyor device in which the tubular return and return belts are provided horizontally in parallel. However, the flow and pressure of the air being injected from the air outlet is not sufficient, so that the belt partially contacts the belt holder made of a steel tube, thereby significantly increasing the resistance to The running of the belt.
