Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a steel lower frame into which a fork can be inserted, a steel upper frame engaged and mounted on the lower frame, and a steel upper frame engaged and mounted on the upper frame. The present invention relates to a powdery and granular material transport storage container comprising a storage section.

[0002]

2. Description of the Related Art Conventionally, powders and granules have been transported stored in bags or boxes. However, when the granular material is stored in the bag, the shape of the bag is not fixed, so that it is difficult to handle. For this reason, bags are stored and transported in boxes or frames.

However, when a bag is put in a box made of metal, plastic, or the like, the bag becomes similar to a tank made of metal, plastic, or the like, and the bag itself is unnecessary. Also, when entering the frame, the center of gravity is biased downward, and the bag protrudes from the frame, resulting in poor storage efficiency. Therefore,
If the girder of the frame is made dense to prevent it from protruding, the form becomes similar to a box and approaches the tank.

When a bag is placed in a frame, it is easy to fill the bag in the frame with the granular material, but unloading is performed by a pump or the bag is taken out, which is inconvenient. Also,
Reusing frames requires large space for storage and transportation, and requires labor during handling. In any case, the transportation and storage of the conventional granules have advantages and disadvantages.

For example, Japanese Unexamined Utility Model Publication No. 55-66989 discloses a technique in which a cut at the bottom of a container is closed by a cover plate, and the contents fall when the cover plate is opened. However, in such a known technique, the residue in the lower lid cannot be discharged unless the body is removed, which makes the operation troublesome and the content is not sufficiently retained.

[0007]

[Problem to be solved by the present invention]
An object of the present invention is to provide a granular material transporting storage container in which the unloading of the granular material is reliable and easy, the handling is easy, and the storage efficiency is good.

[0008]

According to the present invention, a steel lower frame (1) into which a fork can be inserted and a steel upper frame (7) mounted on the lower frame (1) are engaged. 10) and a storage unit (20), which is engaged with and mounted on the upper frame (10), in the four-part corner of the bottom plate (2) of the lower frame (1). A corner post (3) having a notch (3a) for engaging and mounting the frame (10) is erected, and four corners at the center of a grid-like frame (4) provided on the bottom plate (2). The pillar (5) with which the upper frame portion (10) is engaged is provided upright,
The four-peripheral frame (11) of the upper frame (10) is the notch (3a)
A frame (12) is provided inside the four-sided frame (11), and a frame (13) inscribed in the pillar (5) is provided on the lower surface of the frame (12). A downwardly directed quadrangular pyramid-shaped guide portion (14) is attached between the four-peripheral frame (11) and the center of the framework (12), and the storage portion 20 is mounted on the guide portion (14). A slit (14a) to be inserted is formed, and an opening (15) is formed at the center thereof, and a pair of rails (16) is provided at the lower part of the opposite side surface of the opening (15). An opening / closing lid (17) is slidably provided on the rails (16), and the storage section is configured to be foldable with corrugated paper.

Preferably, the storage section is formed of three-layer corrugated paper.

[0010]

In the container for transporting and storing a granular material configured as described above, the granular material is directly charged and stored in a space defined by the storage portion and the upper frame portion.

During unloading, when the opening / closing lid is opened, the granular material is guided by the tapered surface of the upper frame portion and falls from the opening.

When transporting an empty container, the container is disassembled into a lower frame portion, an upper frame portion, and a storage portion, the storage portion is folded, and transported together with the upper and lower frame portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the powdery and granular material transport storage container of the present invention is connected to a steel lower frame portion indicated by reference numeral 1 and is engaged with and mounted on the lower frame portion 1. It is generally constituted by a steel upper frame part indicated by reference numeral 10 and a corrugated paperboard storage part indicated by reference numeral 20 which is entirely engaged with and mounted on the upper frame part 10. However, the storage section 20 may be made of plastic.

3 to 5, at four corners of the bottom plate 2 of the lower frame portion 1, angle pillars 3 made of an angle are provided upright, and an upper frame portion 10 is engaged with the corner pillars 3. A notch 3a to be placed is formed. A grid-like frame 4 is mounted on the bottom plate 2, and the upper frame 1
A pillar 5 with which the engaging portion 0 engages is provided upright.

In FIGS. 6 to 8, the four peripheral frames 11 of the upper frame portion 10 are formed in a shape to be engaged with the four notches 3a of the lower frame portion 1. A lattice-like frame 12 is provided inside the four-peripheral frame 11, and a frame 13 inscribed in the four pillars 5 is provided on the lower surface at the center of the frame 12.
A downwardly directed pyramid-shaped guide portion 14 is attached between the four-peripheral frame 11 and the central portion of the framework 12, and an opening 15 is formed in the central portion. Further, an upward slit 14a is formed on the four circumferences of the guide portion 14. The upper frame 10 is engaged and mounted on the corner pillars 3 and the pillars 5 of the lower frame 1 via the four-peripheral frame 11 and the frame 13.

9 to 11, the opening 1
Angled U-shaped rails 16 and 16 are attached to the lower part of the opposing side surfaces of 5, and the ends are connected by rails 16a. An open / close lid 17 is slidably provided on these rails 16. The opening and closing lid 1
7 is formed in a container shape with one side orthogonal to the rails 16 and 16 missing, and a handle 18 protrudes from the other side. An angle stopper 19 is protruded from the rail 16a.

Returning to FIG. 1, the main body 21 of the storage section 20 is formed in a rectangular tube shape to be inserted into the slit 14a of the upper frame section 10 by three-layer corrugated paper. And this body 21
A reinforcing plate 2 having a bent portion 22a protruding in the middle thereof.
2 are joined. Therefore, the storage unit 20 can be folded into a flat plate by itself.

Next, the operation will be described.

When storing the granular material, the accommodating portion 20 is expanded into a rectangular tube shape, and the lower edge portion is inserted into the slit 14a of the upper frame portion 10, and is defined by the upper frame portion 10 and the guide portion 14. The granules are directly charged into the space to be made.

For transportation, a fork is inserted into the gap A (FIG. 1) between the lower frame 1 and the upper frame 10, lifted, for example, placed on a truck bed, transported, and similarly lowered.

When unloading the granular material, place an empty container or bag (not shown) at the bottom of the container, pull the handle 18 and open the opening / closing lid 17. Then, the granular material is guided by the tapered surface of the side portion 14, falls from the opening portion 15, and is unloaded to an empty container or bag.

When the empty container is transported, the storage section 20 is removed from the upper frame section 10 and folded into a flat plate to form the upper and lower frame sections 1 and 2.
Ship with 10.

[0024]

[Effects of the Invention] As described above, according to the present invention, the following excellent effects can be obtained. (A) The structure for unloading is ensured by the upper and lower frames made of steel, and the operation of the open / close lid is easy. Also, it is not damaged by the insertion of the fork. (B) Since the storage section is made of corrugated cardboard, handling such as folding is easy, and it can be easily assembled by inserting it into the slit of the guide section. (C) The unloading operation can be performed by the open / close lid, and the operation is easy. (D) Since the guide portion is directed downward, the angle of repose can be taken, and the discharge of the granular material is easy.
