Description

Description: TECHNICAL FIELD The present invention relates to a fiber belt with a built-in conductive wire for winding / conveying, which is used in a winding / conveying device for winding / conveying various articles.

[Prior Art] Conventionally, as a hoisting and conveying device using a belt, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Publication No. 3-258389,
The belt is directly hung from the reel for winding and unwinding the belt.

[Problems to be Solved by the Invention]

However, in the case of the conventional hoisting and conveying device, there is no description about what material the belt is made of. Further, there is a drawback that the position of the openable / closable hanger changes laterally when the belt winding amount of the belt winding and reeling-out reel changes.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a supporting device using a fiber belt with a built-in conductive wire for winding and carrying which can easily eliminate the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in a supporting device using a fiber belt with a built-in conductive wire for winding and conveying of the present invention, four winding and conveying fibers suspended from a drum of a hoisting machine are used. A belt 1 is arranged at intervals in the front-rear direction and the left-right direction, and a conductive wire 2 made of a braided copper wire is provided in the fiber belt 1.
However, the fiber belts 1 are woven and incorporated so as to extend in the longitudinal direction of the fiber belt, and the front and rear fiber belts 1 are wound around independent guide rollers 20 and hang down from the guide rollers 20.

[Action]

When the drum 3 in the hoisting machine is rotated in the normal direction, the fiber belt 4 with a built-in conductive wire is wound around the drum 3, and the fiber belt 4 with a built-in conductive wire winds up and conveys the load, and the drum 3 is rotated in the reverse direction. The fiber belt 4 with a built-in conductive wire is unwound from the drum 3, and the fiber belt 4 with a built-in conductive wire winds down and conveys the package. Further, an electric control signal of the power feeding or hoisting and conveying device is sent by the conductive wire 2 incorporated in the fiber belt 1 by being woven therein.

Horizontal running rail 5 fixed to the upper part of the building
Wheels 8 of a trolley 7 having a drive device 6 for traveling are placed on the lower flange of the electric motor 10 and the speed reducer 1 in a box-shaped frame 9 fixed to the lower part of the trolley 7.
The hoisting drive device 12 composed of 1 is fixed, and the intermediate portion of the drive shaft 13 extending in the left-right direction, that is, the direction perpendicular to the extension direction of the traveling rail 5, is penetrated by the speed reducer 11,
Both ends of the drive shaft 13 are supported by bearing members 14 fixed to the frame 9, and the drive shaft 13 is rotated by the electric motor 10 via the speed reducer 11.

The driven shaft 15 arranged in the frame 9 in parallel with the drive shaft 13 includes a plurality of bearing members 1 fixed to the frame 9.
6, a transmission chain 19 is wound around a drive sprocket 17 fixed to the drive shaft 13 and a driven sprocket 18 fixed to the driven shaft 15, and both sides of the drive shaft 13 in the longitudinal direction and Drums 3 of the same shape having a zigzag surface whose diameter gradually increases from the end to the center are fixed to both sides of the driven shaft 15 in the longitudinal direction, and the drive sprocket 17 and the driven sprocket 18 are provided. Have the same number of teeth, and the maximum diameter portion of each of the drums 3 is set to have the same diameter.

The same shape, with a scalloped surface, the diameter of which gradually increases from the end to the center at the front of each drum 3,
A belt lifting guide roller 20 of the same size is arranged,
Both ends of a horizontal shaft 21 on which the guide roller 20 is rotatably fitted are fitted on brackets 22 fixed to the frame 9, and the fiber belt 4 with a built-in conductive wire is wound around each drum 3, and One end of the fiber belt 4 with a built-in conductive wire is fixed to the drum 3, and the fiber belt 4 with a built-in conductive wire
Is wound around the guide roller 20 and hangs down from the guide roller 20, and the hanging lower end portion of each conductive wire built-in fiber belt 4 is connected to the elevating member 23. A left-hand screw on a double-threaded screw rod (not shown) that is provided with clamp members 25 that hold the storage bucket 24 so as to move toward and away from each other, and that is rotated by an electric motor provided inside the elevating member 23. The clamp members 25 on both sides are screwed into the right and left threaded portions, and the clamp members 25 on both sides are moved toward or away from each other by the normal rotation operation or the reverse rotation operation of the electric motor.

In the hoisting and conveying device configured as described above, when the hoisting drive device 12 and the hoisting drive device 12 in the hoisting machine including the four drums 3 are rotated in the forward direction, the respective drums 3 simultaneously move in the take-up direction. Since the fiber belts 4 with a built-in conductive wire are wound around the drum 3, the load such as a bucket supported by the clamp member 25 of the elevating member 23 is wound up and conveyed. Further, when the hoisting drive device 12 is driven in the reverse rotation, the drums 3 are simultaneously rotated in the rewinding direction, so that the fiber belts 4 with a built-in conductive wire are unwound from the drums 3 and the packages are unwound and conveyed. .

Further, the power supply to the electric motor for moving the clamp member in the winding and conveying device and the transmission of the control signal of the electric control circuit are performed by the conductive wire 2 in the fiber belt 1.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

Each fiber belt 1 has an independent guide roller 20.
Since it is wound around the guide roller 20 and hung down from the guide roller 20, the lifting member 23 for hanging the load does not move laterally even if the amount of fiber winding on the drum 3 changes, and the belt is a fiber belt. Therefore, it is softer than a steel belt, and therefore there is no risk of injury even if an operator touches the belt, and the fiber belt 1
Has less torsional rigidity than a steel belt, so the luggage can be easily swung while the luggage is suspended via a plurality of fiber belts, and the conductive wire 2 extending in the longitudinal direction of the fiber belt is Since the fiber belt 1 is woven and built in, even if an operator touches the belt, there is no risk of electric shock, and a plurality of conductive wires 2 can be woven and built in one fiber belt.

When the load is lifted by the fiber belt with a built-in conductive wire, the fiber belt 1 bears the load, but when the fiber belt 1 is worn and stretched due to long-term use, the conductive wire 2 is cut first. As the electric control circuit stops working or power is not supplied, it is possible to detect that the fiber belt has reached the limit of use and replace it with a new fiber belt with a built-in conductive wire. In addition, it is possible to prevent the fiber belt 1 from being suddenly cut and causing an accident.
