Due to the restriction of rotation resistance and rotation speed, there were the following problems. It was difficult to increase the speed due to the restriction of the belt conveyance speed. The generation of noise associated with the rotation of the roller deteriorates the working environment. It took a lot of effort to maintain many rollers. There was vibration of the equipment due to the rotation of the roller. The belt has a short life due to wear caused by rolling and sliding.

The return-side belt is supported on the inner surface of the lower portion of the pipe, is supported on the inner surface of the lower portion of the lower cylindrical pipe of the pair of cylindrical pipes, and is attached to the lower portion of the injection hole formed at the lowest portion of each of the cylindrical pipes. Is connected to a compressed air pipe communicating with a compressed air source and supplying compressed air to the injection hole and extending along the belt running direction, and the cylindrical pipe is provided with an exhaust port for discharging the compressed air after the belt floating action. A belt reversing device for reversing the upper and lower surfaces before and after introducing the return-side belt after reversing at the edge of the belt conveyor device into the lower cylindrical pipe and after passing through the lower cylindrical pipe is provided in front of and behind the lower cylindrical pipe. As configuration, the belt running moves while air levitation. Then, the belt on the return side is reversed by the belt reversing device and introduced into the lower cylindrical tube, so that U on the carrier side in the upper cylindrical tube.
Since the belt whose cross section is bent like a letter passes through the lower cylindrical tube while being bent in a U shape on the return side as well,
As compared with a belt that does not turn over on the return side, the abrasion phenomenon due to the sliding operation on the inner surface of the cylindrical tube at the end of the belt is reduced, and the life of the belt is extended. Further, in the second invention, the belt reversing device is fixed in the axial direction by a pair of upper and lower horizontal scissor rollers at both ends and a pair of left and right vertical scissor rollers provided at an intermediate portion of the both horizontal scissor rollers or an inclined support. The belt can be easily and easily reversed because it is formed of a tilt roller that protrudes by sequentially changing the bulging angle at a plurality of positions spaced apart and abuts and rolls on the back surface of the belt. Further, in the third invention, the trough forming device is arranged between the belt reversing device and the lower cylindrical tube, respectively, and U is provided along the inner surface of the cylindrical tube for guiding the belt after the reversal in advance.
Since it is formed in a V-shaped cross section, it can be smoothly introduced into the cylindrical tube. Further, since the belt after exiting the lower cylindrical tube is guided to the belt reversing device while being held in the U-shaped cross section by the trough forming device in advance, the belt near the outlet of the lower cylindrical tube is flattened (U
(The phenomenon that the character-shaped cross section becomes flat due to the reversing operation of the belt reversing device) is prevented, and unnecessary wear phenomenon is prevented.

0A is another embodiment of the present invention (corresponding to the third invention)
The difference from the belt conveyor device 100 of FIGS. 1 and 2 is that a trough forming device 60 is provided between the belt reversing device 50 and the lower cylindrical tube Q. As shown in FIG. 8, the trough forming device 60 uses the flat belt 1 (actually, the return-side belt 1b),
The return-side belt 1b after being curved into a U-shaped section and smoothly introduced into the lower cylindrical tube Q, or after passing through the lower cylindrical tube Q
However, the return side belt 1 near the outlet of the lower cylindrical tube Q is affected by the reversing action of the belt reversing device 50.
It is installed for the purpose of holding the belt cross section in a U-shape in order to prevent the belt end from being rubbed strongly against the inner wall of the lower cylindrical tube and being worn due to b being flat. Specifically, the pair of upper and lower pressing rollers 6 in the central portion of the belt cross section

側の断面状況を示している。The operation of the belt conveyor device 100 shown in FIGS. 1 to 6 and the belt conveyor device 100A shown in FIGS. 7 to 8 configured as described above will be described. The transported article M is supplied from the inlet 4 on the tail pulley side onto the carrier side belt 1a on the carrier side trough 10, and is transported by the belt driving device (not shown) and the carrier side belt 1a driven by the head pulley 2, It is discharged from the chute 9 on the side. During operation of the belt conveyor device 100 or the belt conveyor device 100A, the carrier side belt 1a and the return side belt 1b.
Respectively move while slightly floating due to the boundary layer of compressed air formed between the carrier side trough 10 and the return side trough 12, and the abrasion with the troughs 10 and 12 is significantly larger than that of the conventional model. Power consumption is reduced. FIG. 2 shows cross-sectional states on the head pulley side and the tail pulley side, respectively.

It moves while floating slightly due to the floating effect of the compressed air introduced and injected into the. Then, after passing through the lower cylindrical tube 50, the belt is turned upside down again by the belt reversing device and returned to the original state, the tail pulley 3 is reversed, and the return side belt 1b becomes the carrier side belt 1a and reaches the input port 4.

な摩擦を防止する。In the belt conveyor device 100A, in the above operation, after the belt is reversed by the belt reversing device 50 after the head pulley 2, the belt 1b is passed through the trough forming device 60 and before entering the lower cylindrical pipe Q in advance. A U-shaped cross section is formed to facilitate the introduction into the lower cylindrical tube Q, and as described above, the belt cross section when exiting the lower cylindrical tube Q is U.
It is held in a character shape to prevent harmful friction between the inner surface of the lower cylindrical tube Q and the belt end.

ある。In the belt conveyor device 100 and the belt conveyor device 100A, the reason why the return side belt 1b entering the lower cylindrical tube Q is reversed by the belt reversing device 50 is that the carrier side belt 1a has an U-shaped cross section in the upper cylindrical tube P. Since the transported goods M are loaded while being transported and moved over a long distance, when the return-side belt 1b passes through the lower cylindrical tube Q as it is, the return-side belt 1b is not flat but rather a reverse U. This is to prevent the belt end portion from sliding on the inner side wall of the lower cylindrical tube Q and promoting friction and wear because the belt tends to have a V-shaped cross section (a V shape).

業環境が清潔良好で、輸送物の逸失もなく有利である。In the belt conveyor device of the present invention described above, a large amount of high-speed transfer can be performed over a long distance, and because of the closed structure, there is no generation of noise or pollution of the work environment due to falling mine, and the conventional problems are solved. As a result, the maintenance is facilitated and the maintainability is improved, and the running cost and initial cost can be significantly reduced by reducing the power consumption. In particular, in the present invention, the lower inner surface is used as a support trough for the carrier-side belt and the return-side belt by skillfully utilizing a horizontal cylindrical tube, and a belt reversing device and a trough forming device are provided on the return side, thereby reducing belt wear. Is significantly reduced, the maintainability is improved, and the operation can be performed safely and stably for a long period of time. Further, since the belt is passed through the cylindrical pipe, there is no drop of the transported material, so the working environment is good and the transported material is not lost, which is advantageous.
