必要となる。2. Description of the Related Art Conveyor belt itself is a cylinder device as a conveyor device capable of large-volume and high-speed transportation without spilling, not only linear transportation but also curved transportation up, down, left and right. A device that is molded into a shape and is conveyed is known. However, in this device, it is necessary to arrange support members at regular intervals to maintain the conveyor belt in a cylindrical shape, which makes the device expensive. In addition, when the conveyor belt is formed in a cylindrical shape, the joint portion of the conveyor belt is at the top, but the returning belt faces downward, and there is a drawback that the remainder of the conveyed material is spilled.
Also, a cover is required to prevent the belt itself from being exposed to the weather.

う利点がある。In order to improve these drawbacks, Japanese Patent Laid-Open No. 4-317911 discloses an outer pipe 21 and an inner pipe 22 arranged inside the outer pipe 21, as shown in FIG. , A flexible conveyor belt 23 running in a curved shape along the lower inner walls of the outer pipe 21 and the inner pipe 22, respectively.
24, air blow holes 25 and 26 are formed in the lower portion and side portions of the outer pipe 21 at regular intervals along the belt longitudinal direction, and air blow holes 27 are also provided in the lower portion of the inner pipe 22 in the belt longitudinal direction. There is disclosed a conveyor device which is provided at regular intervals along. According to this conveyor device, the outward conveyor belt 24 having a curved shape along the inner wall of the lower portion of the inner pipe 22
Is driven by the air blown from the air blowing hole 27, while the return conveyor belt 23 having a curved shape along the inner wall of the lower portion of the outer tube 21 is floated by the air blown from the air blowing hole 25. it can. That is, since the outward path belt and the return path belt are externally housed in a single pipe, it is possible to prevent the entry of wind and rain and the spillage of the conveyed product M, and the conveyor belt is the inner circumference of the inner and outer pipes. Since it moves along the surface, there is an advantage that there is no support member for the conveyor belt and maintenance is unnecessary.

The air filter 28 will be further described with reference to FIG.
The air pipes 30 and 31 are connected in parallel to the blower 29 having the air blower 29, and the damper 32 and the air nozzle 33 are connected to one air pipe 30.
, The air nozzle 33 communicates with the lower air blowing hole 25 through the air duct 34, and the other air pipe 31 has the damper 35 and the duct 36 through which the side air blowing hole 2 is connected.
It leads to 6. In the air blowing facility configured as described above, the flow rates of the air blown from the blower 29 into the air pipes 30 and 31 are adjusted by the dampers 32 and 35, respectively, and then the air blowing holes 25 are passed through the ducts 34 and 36. Two
6 is blown into the outer tube 21. Lower air blow hole 2
The air blown into the outer tube 21 from 5 pushes up the return conveyor belt 23 running along the lower portion of the inner wall of the outer tube 21. The air after pushing up the return conveyer belt 23 and the air blown into the outer tube 21 through the side air blowing holes 26 are provided in the lower portion of the inner tube 22 because both ends of the outer tube 21 have a sealed structure. The forward conveyor belt 24, which is blown into the inner pipe 22 through the air blowing hole 27 and runs along the lower portion of the inner wall of the inner pipe 22, is pushed up. In this way, it is possible to travel with both the forward conveyor belt 24 and the backward conveyor belt 23 floating.

If the amount is too large, the conveyor belt will float abnormally and come into contact with the upper structure, or the excessive amount of air will cause the conveyor belt to flap, vibrate or generate noise. That is, as shown in FIG. 6, when the amount of the conveyed product M is smaller than the amount of air blown from the duct 12 through the air blowing hole 2a, the conveyor belt 6a rises abnormally and comes into contact with the upper cover 1.

る。In the conveyor device constructed as described above, the conveyed product can be conveyed as follows.
In the conveyor apparatus having the configuration shown in FIG. 1, a conveyed product is put into the outward conveyor belt 6a from the input port 3 and the conveyor belt 6a is made to travel in the direction of the arrow by the drive side pulley 5.
Then, when the amount of conveyed goods is small and the motor load (current value) of the drive pulley 5 is small, the operation of the blower 8b is stopped according to an instruction from the control panel 7, and only the blower 8a is operated. Eventually, when the transport amount of the transported object increases and the motor load (current value) of the drive-side pulley 5 increases, both of the two blowers 8a and 8b are operated according to an instruction from the control panel 7. In this way, by controlling the operating number of blowers according to the motor load of the drive pulley 5, it is possible to feed an appropriate air volume according to the transport amount of the transported object, so as shown in FIG. The conveyor belt 6a is pushed up from the inner surface of the guide plate 2 by an appropriate amount,
It is possible to travel in a stable floating state. In addition,
If the number of blowers is appropriately increased according to the expected fluctuation of the transport amount, it becomes possible to finely adjust the blown air amount.

Alternatively, a method of adjusting the opening degree of the electric valve 18 may be used. This method is also similar to the case of controlling the operating number of a plurality of blowers in FIG. 1 by decreasing the valve opening degree when the conveyance amount is small and increasing the valve opening degree when the conveyance amount is large. Since it is possible to feed an appropriate amount of air according to the carry amount of the conveyor belt, as shown in FIG. 3, the conveyor belt 6a is pushed up by an appropriate amount from the inner surface of the guide plate 2 and can run in a stable floating state.
