Description

[Detailed explanation of the invention] (Industrial application field) This invention can be used for rice, wheat, other grains, and granules.
This is related to flexible containers (commonly called flexible containers) that are packed in bulk weighing 500 kg and 1 ton, and is particularly useful for transporting large numbers of flexible containers filled with grains etc. within warehouses, loading them onto vehicles, etc. Or it relates to an auxiliary tool used when lowering the vehicle.

(Prior art and its problems) Flexible container A, which is generally used for storing rice, is a cube-shaped bag with a side of 1 m, and the upper opening can be tied.
Furthermore, in order to suspend this flexible container, two wide and strong bands B ₁ and B ₂ , each having a width equivalent to about half of one side of the container, are sewn in parallel at both ends to a pair of opposing sides. These two bands B ₁ and B ₂ are hooked onto the hook F of a crane and transported by hanging (see Figures 1 and 2).

However, the lengths of these bands B ₁ and B ₂ have to be widened to the left and right so as not to obstruct the opening of the flexible container A in order to take grains in and out of the flexible container A. When the flexible container A is full of grains, the two bands B ₁ ,
When this is hung using B ₂ , the grains in the upper part of the flexible container A are gathered to the center due to the weight of the grains inside, and the height H ₁ of the bands B ₁ and B ₂ and the bag part are The height _H2 of A becomes almost the same dimension, requiring a large hanging allowance when carrying out cargo handling with a crane, reducing the number of multi-tiered stacks of these flexible containers A, and reducing the effective utilization volume ratio in the warehouse. It's summery. Moreover, even if the bands B ₁ and B ₂ are lifted using a forklift,
Since the lifting height _H1 is large, when loading onto a boxcar, only one layer can be stacked, resulting in relatively high transportation costs.

(Problem to be Solved) This invention reduces the hanging dimension to less than half of the conventional size without any modification to the flexible container A, which is provided with a pair of wide hanging bands as described above. Preferably, it should be reduced to about one-third, so that the number of stacking stages of flexible containers in storage warehouses and freight cars can be increased;
The purpose is to enable easy installation and removal of flexible containers.

(b) Configuration (means for solving the problem) In order to achieve the above problem, a rectangular structure made of one type of rod, pipe material, or shape material with high strength and rigidity and having a size that roughly matches the planar contour shape of the flexible container. At least one crosspiece is fixed to the center of the shaped frame, and is a part of the crosspiece and is located at a diagonal intersection of the frames,
In addition, in the case where a hook hooking part for hanging the cargo handling machine is provided in a plane containing the frame or in a position very close to the plane, the rectangular frame further stands up slightly from one side and extends toward the center of the frame. This auxiliary tool for hanging a flexible container is characterized in that the arm is provided with an arm extending from the side, and the free end of the arm is provided with a second engaging part which can be engaged with a hook for hanging a cargo handling machine.

(Function) To use the auxiliary device of this invention configured as described above, fill the flexible container with grains, etc., close the container, and then insert the auxiliary device of this invention into one short Insert it under the pair of bands provided at the top of the container in the direction from the side to the long side.

When lifting a cargo handling machine using a crane, for example, insert the hook of the crane from above between the pair of bands, engage the hook F in the center of the frame, and lift it up. .

In this way, when the flexible container is suspended, the pair of bands engage the upper surface of the auxiliary device of this invention, bend and tension against the mold, and as the auxiliary device rises, the lower bag portion is lifted up. (See Figure 4).

On the other hand, when handling cargo using a forklift, after inserting the auxiliary device of this invention under the pair of belts in the same way as described above, insert the claw of the forklift under the auxiliary device of this invention, Pull up the claw and carry it. In this case too, the band is tensioned in shape (see Figure 5).

For cargo handling, the auxiliary device of this invention is pulled out to the side, separated from the flexible container A, and used for cargo handling of the next flexible container.

In addition, in this device, the second engaging portion of the free end of the arm extending from one side of the frame toward the center of the frame is engaged with the hanging hook of the cargo handling machine, and the entire frame is attached to a pair of belts. After inserting it from one side to the bottom, hang the flexible container by replacing the hanging hook of the cargo handling machine with the hook hooking part at the center of the frame.

When removing the frame of this invention, perform the procedure in the reverse order of insertion.

Of course, the second hooking section may not be used, and only the hook hooking section at the center of the frame may be used to hang the flexible container from the hook of a cargo handling machine to engage and release the hanging strap of the flexible container.

(Embodiment) A typical embodiment of this invention shown in FIGS. 3 to 6 will now be described.

In FIG. 3, reference numeral 10 denotes a frame with great strength and rigidity, such as an iron pipe, and the length of one side is approximately the same as the length of one side of the flexible container A. In the illustrated example, a pair of The sides have a planar rectangular shape slightly narrower than one side of the container A, and the four corners are rounded 11. A bar 13 is integrally provided near the center of the frame 10 in a direction parallel to the short side 10a of the frame 10, and in the example shown in FIG. 3, two bars 13 are provided close to each other in parallel. be.

Reference numeral 12 designates a hook engaging portion for hanging a cargo handling machine that connects the central portions of the two beams 13, and has a slightly chevron shape. As shown in FIG. 7, in the case where one crosspiece 13 connects the centers of a pair of long sides 10b of the frame, a hooking portion 12 is provided at the center.

In other illustrated examples, the frame 10
Attach this auxiliary tool to flexible container A,
A second hooking portion 15 is provided in a part thereof to be hooked to a hook for hanging the cargo handling machine for removal.

That is, the steel rod 16 is bent into a V-shape, both ends 17 and 18 of which are welded to the outside of the short side 10a of the frame 10, and this is bent above and inward to form the V-shape of the steel rod 16. The second engaging portion 1 is formed by the tip portion bent into a mold.
5 is formed, and the position of this second engaging portion 15 is formed to reach near the center position when the frame 10 is viewed from above.

In the illustration, the steel rods serving as the arms of the second hooking portion 15 are bent into two pieces to make them strong, but one rod is made to protrude and its tip is formed into a ring to provide the second hooking portion. However, the idea is the same (see Figure 7).

In the above example, the rectangular frame 10 is made of a pipe with high strength and rigidity, such as an iron pipe, but it may be made of other materials, and the cross-sectional shape does not have to be circular, but can be any shape such as U, T, or I. This idea is the same even if it uses a shaped material with a cross-sectional shape.

To use the auxiliary device of this embodiment configured as described above, fill the flexible container A with grains, etc., close the mouth of the container A, and then insert the auxiliary device of this invention into one side. It is inserted under the pair of bands B ₁ and B ₂ provided at the top of the container A from the short side 10a toward the long side 10b.

Therefore, when suspending a cargo handling machine using a crane, for example, a pair of straps should be attached from above.
A hook F of a crane is inserted between B ₁ and B ₂ , and the hook F is engaged with the hook engaging portion 12 at the center of the frame 10 to lift it up.

In this way, when the flexible container A is suspended, the pair of bands B ₁ and B ₂ engage with the upper surface of the auxiliary device of this invention and are bent and tensed into the shape, and as the auxiliary device rises, the lower part (See Figure 4).

On the other hand, when handling cargo using a forklift, use the aid of this invention with a pair of belts as described above.
After inserting it under B ₁ and B ₂ , insert the claw C of the forklift under the auxiliary tool of this invention, pull up the claw C and carry it. In this case as well, bands B ₁ and B ₂ are
I am nervous about the shape (see Figure 5).

After cargo handling, pull out the aid of this invention to the side.
It is separated from flexible container A and used for cargo handling of the next flexible container A.

C. Effect Since the device of this invention has the structure and function as described above, if the second hook is hooked to the hook of the cargo handling machine and suspended, the position of the second hook will be the same as the frame when viewed from above. Because it extends from the center,
The frame itself is supported almost horizontally, and in this state it can be passed through and removed from the pair of bands of the flexible container sequentially from one direction, and the flexible container can be suspended using the auxiliary device of this invention. When lowering it, all you have to do is rehang the cargo handling machine's hook on the hook hooking part in the center of the frame, making cargo handling setup work much more efficient.

Of course, when the frame is engaged with the pair of bands of the flexible container, it is also possible to engage the hook of the cargo handling machine with the hook engagement portion at the center of the frame.

In addition, by simply inserting the frame of this auxiliary device into the underside of a pair of flexible container bands,
The pair of bands will be bent to follow the frame, and most of the bands will be horizontal along the top surface of the frame, so the dimension from the hook hooking part to the top surface of the flexible container will become smaller, allowing cargo handling. The number of multi-level stacking of flexible containers by machine can be increased.

In addition, this invention can be used as is without any modification to the flexible container in the shape shown in Figure 1, which is widely used in distribution and storage operations, and when it is hung, it becomes a flexible container. Since the container is suspended while maintaining its almost cubic shape, even if there are grains, other granules, powder, etc. in a flexible container, the top surface of the granules will not be piled up in a mountain shape as in conventional containers. The container remains flat, eliminating the need to level the surface of the flexible container with the granules inside after cargo handling.

(Effects Unique to the Embodiment) In this embodiment constructed and operated as described above, it can be easily inserted and removed from the bottom of the bands B ₁ and B ₂ of the known flexible container A. Simply insert a pair of flexible bands
B ₁ and B ₂ are not bent in a Λ shape, but are bent in a shape following the auxiliary tool, and most of the length of the bands B ₁ and B ₂ is the width direction dimension along the top surface of the frame 10. , the vertical dimension is small, and the engaging part 1
2 is also provided at a position very close to the plane containing the frame 10, so that the hooking portion 1 can be connected from the top surface of the bag portion _A0 .
When a known flexible container is used, the hanging dimension up to 2 is less than half that of the conventional method, and in the example is less than one third.

Furthermore, even when hanging using the claws C of a forklift, the hanging dimensions of the bands B ₁ and B ₂ can be reduced to approximately one-half.

Therefore, even though it was previously possible to stack grains in flexible containers A in three levels in a warehouse using an overhead crane, it is now possible to stack them in four levels, allowing them to be stacked in two levels on a boxcar. You can also do that.

Furthermore, when the auxiliary device of the embodiment of this invention is used as described above, the sewn portion 14 between the bands B ₁ and B ₂ and the bag portion A ₀ becomes
When the flexible container A is suspended, it is pulled up vertically, so the shape of the flexible container A is maintained almost as a cube, and the top surface of the grains in the container A also remains flat. Therefore, it is not necessary to return the top surface of the grains to a flat shape from the outside of the flexible container A after each cargo handling operation.

Furthermore, since the structure is as described above, there is no risk of deformation or failure during hanging.

Furthermore, in this embodiment, frame 1
0 is provided with a second hooking part 15, so if you use this second hooking part 15 to hang only the auxiliary tool of this invention with the hook of the crane, even if the auxiliary tool is a little heavy, , as shown in Figure 6,
The auxiliary equipment can be attached to and removed from the flexible container while suspended, reducing work and safety.

The position of this second engaging part 15 is the center position of the frame 10, that is, a position that does not overlap with the engaging part 12,
That is, it is provided at a position where it does not get in the way when the flexible container A is suspended using the hooking part 12 of the auxiliary tool.

Since the beams 13 are provided in the direction in which the bands B ₁ and B ₂ are engaged and compressive stress is applied, there is no fear that the frame 10 will be deformed by the load during suspension.

In addition to the above-mentioned crane and forklift, the cargo handling machine used when this invention is used may be a hanging conveyor, a wire cable lift, a ship's derrick, or the like.
