Description

[Detailed Description of the Invention] The present invention relates to an improvement of a container for transporting powder and granules, and provides a container that can be easily handled by a forklift and can be transported efficiently.

In recent years, improvements have been made in marine transportation by ships, and so-called container ships have come to be used more frequently.

This involves loading containers filled with powders and granules such as cement, sugar, and industrial chemicals into a predetermined number of box-shaped sea containers, which are then loaded onto a predetermined number of sea container ships for transport. This is an attempt to streamline work.

Therefore, it is necessary to load each container onto a sea container in advance at a separate location.

Conventionally, containers for powder and granules have generally been made of flexible sheet-like materials made of woven fabric or laminated with sheets, and are transported by lifting them with a crane or forklift using a hanging rope attached to the body of the container. Was.

However, the marine containers mentioned above usually have a door on the side and cargo is loaded in and out from the side, so cranes cannot be used to load containers, and forklifts cannot be used to load containers. When lifting, it was impossible to load onto the upper level.

Furthermore, when lifting with a forklift, it was necessary to use a special attachment or cover the fork with battens or cloth to avoid damage to the hanging rope.

Therefore, when transporting a container filled with powder or granules to a sea container, the container is placed on a pallet made of wood or the like that has an insertion part for inserting the fork of a forklift.

However, since this pallet has the insertion portion as described above, it is usually about 120 mm in height, and when it is loaded into a sea container, it wastes space, resulting in a problem of poor transportation efficiency.

Furthermore, since it costs a lot of money to recover the pallets from the destination after transportation, even relatively expensive pallets often have to be disposed of.

The present invention has been made in view of the above.

The present invention will be explained according to the embodiments shown below.

In Fig. 1, reference numeral 1 denotes a container made of a flexible sheet-like material, and is formed into a sealed shape with a rectangular cross section by a bottom surface 3, four side surfaces 4.5.5 degrees, and a top surface 6. , the upper surface 6 has a filling lower and a locking hole 8 that can be opened and closed.

Furthermore, the center portion 3a of the bottom surface 3 has a width approximately corresponding to the distance between both forks of the forklift and slightly smaller than this.
Two opposing side edges 3 b , 3 on the bottom surface 3
A bulge is formed downward from b, and step portions of approximately equal dimensions are formed on both sides of the step portion, and the space formed by the step portions on both sides is used as the fork insertion portions 2, 2.

Such a container can be easily loaded into a sea container by inserting it into the fork insertion part 2 using a commonly used forklift, and since no pallet is required, there is no cost associated with collection or disposal. Since there is no need for this and there is less wasted space, transportation costs can be reduced.

Another embodiment of the invention is shown in FIG.

In the figure, a container 1 is formed similarly to the embodiment shown in FIG. 1, and includes a filling lower and a locking hole 8.

Further, the central portion 3a of the bottom surface 3 is formed to bulge downward from the side end portions 3b, 3b in the same manner as described above, and the fork insertion portions 2, 2 are formed by stepped portions on both sides. In this case, a guard 10 covering the open longitudinal side and lower part of the insertion portion 2 is provided from the side surface 4 to the center portion 3a of the bottom surface 3.

Incidentally, reference numeral 9 denotes a discharge port provided in the central portion 3a of the bottom surface 3, which can be opened and closed freely, and is provided as appropriate in consideration of convenience during use.

In the case of such a container, not only is it possible to facilitate cargo handling by a forklift and reduce transportation costs as in the above embodiment, but also it is possible to reduce the amount of powder filled in the container.・It also has the feature of making it easy to discharge granules.

That is, in the case of the embodiment shown in FIG. 1, when a discharge port is provided on the bottom surface 3 and a fork is inserted into the insertion part 2 using a forklift to perform the discharge operation, as the discharge progresses, Since the shape of the container collapses and the bottom surface 3 gradually curves downward, the container eventually falls between the forks, making it difficult to discharge the container.

On the other hand, in the case of the container shown in this embodiment, even if the shape of the container collapses and the bottom surface 3 gradually curves, the fork is held by the guard 10 and the bottom surface 3 is pulled by the two forks. It is efficient because the ejecting work can be carried out until the end without falling between the forks.

Further, as shown in FIG. 3, one end thereof is joined to one side surface 4 of the container shown in the above embodiment, and the other end is joined to another side surface 4 parallel to said side surface 4 through above the top surface 6. two bells forming a space 17.17)
15.15, the fork of a forklift can be inserted into this space 17.17, and even if the container is deformed when discharging powder/granules, this belt 15.15
Since the fork can be wrapped around the fork, it is convenient in the same way as the embodiment shown in FIG.

Note that this belt 15.15 is attached to the container shown in Figure 2.
It is also possible to provide

In the embodiments shown above, both the case where the locking hole 8 is provided and the case where it is not provided are illustrated, but this locking hole 8 is provided from the point of view of automatic container feeding and automation of filling operation, as will be described later. is preferred.

As a flexible sheet-like material for forming the container, a sheet laminated to a woven fabric is suitable for both strength and moisture resistance.As the woven fabric, a material made of polyethylene or polypropylene is suitable; Polyethylene, polypropylene, and kraft paper are suitable, but are not necessarily limited thereto.

Further, the guard 10 and the belt 15 can be made of the same materials as mentioned above, or may be made of other strong synthetic resins or the like.

It should be noted that the guards 10 do not necessarily need to be continuously provided with a length equal to the entire length of the side pieces of the container as shown in the figure, but guards 10 of a predetermined length can be provided at predetermined intervals taking into consideration the strength of the material.

In addition, bonding methods for forming containers include adhesive,
There are various methods such as heat fusion and suturing.

As described above, the container according to the present invention has a closed container with a rectangular cross section formed of a flexible sheet-like material, and has fork insertion portions 2 on both sides of the bottom surface.
2, the container can be directly lifted and transported by a forklift without using a bulky pallet.

In particular, in the present invention, the center portion 3a of the bottom surface 3 of the container 1 is arranged approximately corresponding to the distance between both forks of the forklift.
With a width slightly smaller than this, two opposing sides on the bottom surface 3
The two side end portions 3b, 3b are bulged downward to form step portions of approximately equal dimensions on both sides, and the space formed by the step portions on both sides is formed as the fork insertion portions 2, 2. Therefore, when the forks of the forklift are inserted into the insertion parts 2, 2, the downwardly bulging central part 3a fits between both forks, and this restricts the left-right movement of the container. In addition, since the left and right insertion portions 2.2 are symmetrical in size and shape, the center of gravity is
The book can be lifted in the center between the forks, and even though the container is made of flexible sheet-like material and contains powder or granules, the container can be directly balanced on a forklift. It can be easily lifted and transported.

Moreover, the powder and granules can be stored in the central part 3a that bulges downwards on the bottom surface 3 of the container 1, eliminating wasted space and increasing transport efficiency. Since this is due to the stepped portion, there is no problem in ejecting the powder/granules from the outlet provided in the central portion 3a.

Moreover, since it can be formed at a lower cost than pallets made of wood or the like, transportation costs can be reduced.

Furthermore, when the guard 10 is provided as shown in Fig. 2, it not only has the above features but also is extremely efficient because powder and granules can be discharged from the bottom discharge port while the container is being held by a forklift. good.

Furthermore, since the container has a rectangular cross-section, it has good ability to return to its original shape when filled with powder and granules, and can be folded regularly and flat, making it possible to stock a large number of containers in a small space. .

Therefore, it is possible to automate filling and automatically supply containers.

For example, the usage state of a container of the present invention provided with a locking hole 8 is shown in FIGS. 4 to 6, and in FIG.
is a regularly folded container with rails 23
A hook 24 slidably attached to the hook 24 is engaged with the locking hole 8 and suspended.

This folded container 1a is conveyed below the hopper, and the hopper outlet 22 is inserted into the opened filling lower to start filling with powder/granules.

The filled container 1 is transported in the direction of the arrow in the figure,
Filling is then performed by repeating these operations one after another.

In the evening, this series of operations can be performed automatically.

Further, FIG. 4 shows an example of a so-called rotary system in which the rail 23 is formed into an annular shape, and FIG. 6 shows an example in which a movable hanger 26 is used in place of the fixed rail 23.

As described above, the container according to the present invention is easy to transport, has low transportation cost, and is extremely useful because it can be automatically filled.
