[0016]

The method of transporting the powder or granular material of the present invention will be described by using the filling device of the present application having the above-mentioned configuration. First, the device 1
The hopper 10 and the outlet 100 are arranged right below the outlet 100 such as a grain storage, and the flexible hose 101 is used.
Connect by Next, as shown in FIG. 2, the reversing belt 12 is set on the container mounting table 3, and then the container 50 is placed on the mounting table with the powder / granule inlet / outlet 55 facing upward, and thus the upper surface of the container is Down and the hangers 57
Is appropriately sandwiched between the upper surface 52 and the mounting table 3, and the powder / granule inlet / outlet 55 is fixed around the hopper using the pressing fixture 11.

Next, the air cylinder is operated to lower the container holding frame to the bottom dead center, and the container 50 is moved to the bottom end 57a, ...
After supporting the container, the container holding frame 9 is raised to an appropriate position so that the weight is not applied to the doorway 55 when the container is filled with the powder or granular material. Then, adjust the shape. In this state, the outlet 100 is opened to fill the container with a predetermined amount of grain or the like. Since the container is suspended and supported by the hook 9a, there is no fear that the container will be greatly deformed or fall due to the advancing pressure of the granular material. When the filling is completed, the door is closed, the container holding frame 9 is lowered again to an appropriate position, and the hooks 9a, ... Are removed.

Next, as shown in FIG. 6, the reversing belt 12
The ring 12a of 11 is raised along the side surface of the container 50 filled with the powder and granules, and the wire 16 of the electric winch 15 is connected by the hook 16a. At this point, the container holding frame 9 is raised to the position indicated by the chain double-dashed line in FIG. 6 so as not to disturb the rolling of the container 50. When the electric winch 15 is operated in this state, the wire 16 is wound up, and accordingly, the container 50 starts inverting.

When the container 50 reaches the position indicated by the chain double-dashed line in FIG. 6, that is, the position where the side surface is pressed against the fulcrum bar 13, the fulcrum bar 13 contacts a little below the center of the side surface of the container. Since the height is set, the weight balance causes a rotation moment to rotate rightward about the fulcrum bar 13, and the container is easily inverted, and is indicated by a dashed line in FIG. As shown
The bottom surface having the granular material entrance / exit 55 is at the bottom, and
Stand upright on the ground as a reference plane with the upside down.

In the hanging hands 57, 57 of this container 50,
Insert the fork of a forklift, lift it and load it onto the truck bed. By repeating this operation, the required amount of powder and granules is transported to the destination when loaded on the truck. At the destination, the cargo handling machine carries it to the storage, opens the powder / granular entrance, and drops and stores it. If you bring the empty container back, you can use it for the next transportation.

In the above embodiment, the belt-shaped belt is used as the flexible strip, but it may be a single cord.
Also, on the container mounting space, make a V shape,
It may be a string arranged. Further, the flexible strip and the tow rope may be used as one body without being separated, and in that case, after the container is inverted, the flexible strip is automatically returned to the original position. Resetting can also be easily performed, for example, by tying a return rope to a proper position of the flexible strip and providing a means for pulling back the rope.

When the container is suspended by the hook 9a, it is possible to provide a suspender dedicated to the hook on the bottom surface. The engagement between the slider and the guide pole may be any known configuration as long as the slider moves up and down smoothly. The slider driving means is not limited to the fluid pressure cylinder,
Any linear drive means can be used as long as it does not violate the gist of the present invention, such as drive by a cable and a pulley or drive by a rack and pinion. Further, in the embodiment, the moving base with casters is exemplified as the base, but this is
It goes without saying that a fixed base such as a concrete base cast on the ground with a predetermined thickness may be used. The container mounting space may be the height of the base, but if it is provided at a high position, there is an advantage that the force required for reversing is small and the strength of the frame is small.

[0023]

[Effect] According to the device of the present application and the transportation method using the device, the management of the container becomes extremely easy, and unlike the conventional case, it is possible to save the trouble of opening and tying the opening for each transportation.
Transport work can be done efficiently. In addition, the powdery- or granular-material filling device of the present application employs a flexible strip for reversal and a reversal assisting means, so that a heavy object that reaches 500 to 2000 kg,
It can be reversed with a comparatively small tensile force, and therefore the equipment of the device can be simple and can be supplied inexpensively as a whole. In addition, since the container has only one opening, the manufacturing cost is significantly reduced.
