However, in such a conventional belt conveyor device, a large amount of power is required to convey a large amount of conveyed objects over a long distance, and various types of rollers are required. There were the following problems due to restrictions on rotational resistance and rotational speed. It was difficult to increase the speed due to the restriction of the belt conveyance speed. The work environment was degraded due to the noise generated by the rotation of the rollers. Labor was required to maintain a large number of rollers. There was vibration of the equipment due to the rotation of the rollers. Life is short due to wear due to belt rolling and sliding. Since the load side of the belt on the return side is on the lower side, some of the load attached to the load side may fall off during traveling on the return side and fall off, polluting the inside of the equipment and the surrounding environment. there were. In the carrier-type flat belt conveyor, a certain amount of tension must be applied to the belt on the carrier side in order to eliminate slack between two adjacent rollers in the belt running direction. Because it was close to the inside, the curvature was limited and it was not suitable for running. In addition, in carrier type flat belt conveyors,
Since the belt on the return side is flat and transported in a horizontal state, there is also a problem that it is difficult to provide a curvature. Further, in a belt conveyor device having a curved portion which is curved in a vertical direction along the belt traveling direction, in a curved portion where the side view of the curved portion is convex upward, the belt lower surface contacts the belt lower surface due to the driving tension of the belt. In other words, there is a problem that the belt lower surface is separated from the roller at a curved portion where the side view of the curved portion is concave upward and the running becomes unstable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a first aspect of the present invention, an endless belt and a plurality of compressed air injection holes for floating the belt on both the carrier side and the return side of the belt are provided in the belt running direction. With a belt bearing trough,
A belt conveyor device including an air-floating belt conveyor having at least one curved portion that is curved in a vertical direction along a belt traveling direction, the return immediately after being inverted by a driving pulley at an edge of the belt conveyor device. A belt reversing device for reversing the upper and lower surfaces of the side belt and the return belt immediately before reversing by a tail pulley at the edge of the belt conveyor device, wherein the belt support trough is a pair of upper and lower resin pipes or steel pipes, respectively. The carrier-side belt is supported on the lower inner surface of the upper cylinder (ie, the upper cylinder) of the pair of cylinders, and is formed on the return side. The belt is supported on a lower inner surface of a lower cylinder (that is, a lower cylindrical tube) of the pair of cylinders, and each of the cylinders is An air duct is provided below the injection hole formed in the lowermost portion along the belt running direction and communicates with a pressure air source to supply compressed air to the injection hole. A pipe is connected, and an exhaust port for discharging the compressed air after the belt levitation action is provided in the cylindrical body, and at the lowermost part of the belt support trough at a curved portion where the side view of the curved portion protrudes upward in the curved portion. The pitch in the belt running direction of the compressed air injection hole to be bored is smaller than the pitch in the belt running direction of the compressed air injection hole in the straight portion of the non-curved portion, and the injection holes are densely arranged, and the curved portion is viewed from the side. In the curved part where the upper part is concave upward, the pitch in the belt running direction of the compressed air injection hole formed in the lowermost part of the belt support trough is larger than the pitch in the belt running direction of the compressed air injection hole in the straight part of the non-curved part. Since placing the comb injection hole coarse, it can be provided with a Kyokuhashi portion having an arbitrary curvature in the range not interfering with the position required, and,
By moving the running belt while levitating the air, it is possible to convey the goods continuously at high speed in a closed structure. Also, in particular, a large amount of compressed air is supplied to a curved portion having a convex side view, and the supply of compressed air is reduced to a curved portion having a concave side view, so that the belt is smoothly transferred.

Further, since the belt whose section is bent in a U-shape on the carrier side in the upper cylindrical tube passes through the lower cylindrical tube while being bent in the U-shape also on the return side, the belt which is not inverted on the return side is also used. As compared with the above, the wear 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.

2 to 14E, a pair of upper and lower carrier-side belt support troughs 10 (upper cylindrical tube P) and a return-side belt support trough 12 (lower cylinder) connected by an air duct 22 as shown in FIGS. Since the pipe Q) is the main structure and is only supported on the ground by column bases 40 intermittently arranged in the belt running direction, a large number of pipes Q) are provided in the belt running direction as in the conventional belt conveyor device. A frame (also called a conveyor frame) for supporting the arranged carrier rollers becomes unnecessary, and the equipment cost is greatly reduced. That is, the pair of upper and lower cylindrical pipes P, Q themselves are relatively lightweight, but have rigidity and also function as a cross beam, so that the gantry as the cross beam of the conventional belt conveyor device is used. May be omitted. Therefore, in the case of a long distance span or an inclined conveyor, the effect of omitting the gantry becomes remarkable.
