Description

[Detailed Description of the Invention] This invention relates to a bag-shaped container suitable for transporting and storing large amounts of powder and grains such as grains.

Traditionally, for example, grains have been transported and stored in 60 kg jute bags, etc.
・There are no storage methods in place, and some bulk bulk processing methods and bulk storage in silos, etc., are used.
Due to equipment costs, etc., it was not suitable for the scale of farming in Japan, and there was a strong desire for a container that could be transported and stored in large capacity units by taking advantage of the economic efficiency of bags.

However, bags are easily deformed, have poor workability during transportation, and are unsuitable for stacking, etc., which has hindered their rational use.

Therefore, the purpose of this invention is to provide a large storage bag that has excellent workability when filling and discharging powder and granules into the bag, and is suitable for moving, transporting, and storing bags by stacking them. .

In other words, this device consists of a nearly cubic bag with openings for injection and drainage on at least one of the top and bottom sides, a reinforcing band is provided along the ridgeline of the bag, and a reinforcing band is also wrapped around the body. By providing at least a pair of cross-shaped body tightening ropes, which are provided in the vertical direction on the top or side of the body, and which tighten the reinforcing bands on two opposing sides of the body from within the bag, bulge of the bag during filling with powder and granules can be prevented. It also prevents deformation, adjusts the length of the trunk by changing the length of the trunk rope, allows storage in the same bag even if the amount of filling changes, and maintains the cuboid shape. It is characterized by easy transportation and stacked storage.

In addition, measures such as providing belts, hooks, slings, etc. on the top or side surfaces to suspend the bag during movement or transportation, and reinforcing the bottom by sewing a reinforcing band or separate fabric. It is obvious to use it.

This invention will be explained below based on examples.

The powder storage bag according to this invention consists of a substantially cubic bag body 1 made of a flexible material, with a substantially square opening with the same diagonal line on the top surface, and a cylindrical opening 2 made of cloth or the like.
is sewn along the opening to create an inlet 3 for the powder and granular material, a circular opening is provided in the center of the bottom surface, and a discharge port 5 is created by sewing the cylindrical opening 4 along the opening in the same way. be.

The injection port 3 is closed by tying its mouth with a string or the like.

The discharge port 5 is made by sewing a flap cloth 6 with a notch of approximately the same size as the diameter of the tube mouth 4 in the center on the bottom surface, and forming a chrysanthemum-shaped flap, that is, six flaps by making notches in six directions in the drawing. A flap reinforcing band 7 is sewn to each flap from the ridgeline of the bottom to its tip, the six tips are each sewn into a cylindrical shape, and a tightening string 8 is passed through the tube to form a hexagonal ring. The flap reinforcing band 7 is fastened toward the center of the opening, and the cylindrical opening 4 of the discharge port 5 is folded into the flap and the flap is tightened to close the discharge port 5.

As with the other reinforcing bands below, this flap reinforcing band 7 can be made of woven fabric or synthetic fiber tape having high tensile strength and low elongation properties, and may be used in an appropriate width.

- Next, reinforcing bands 9 having, for example, high tensile strength and low elongation properties are sewn to all ridgeline portions of the bag body 1.

Further, torso reinforcing bands 10 are sewn to the four sides of the bag 1 so as to go around the bag.

This trunk reinforcing band 10 is made into a pair with opposing sides, and the bag body 1
The trunk ropes 11 are strung together from the inside and their lengths are adjusted to change the amount of projection of the trunk and to prevent the trunk from bulging when filled with granular material.

It is preferable to provide one or more pairs of trunk ropes 11 constituting the pair of cross shapes depending on the length of the trunk.

Further, one or more pairs may be provided in the same trunk reinforcing band 10.

On the other hand, it is also advisable to provide a longitudinal reinforcing band or a synthetic resin plate on the trunk and attach a trunk rope to this.

Further, a band similar to the reinforcing band 9 is stretched from both ends of one side of the upper surface of the bag body 1 to both ends of the opposite side, and two pairs of hanging ring bands 12 are sewn to the reinforcing band 9 and parallel to each other.

The suspension ring 12 suspends the bag 1 by passing through the fork 17 of a forklift vehicle, as will be described later, and its length may be selected as appropriate.

Furthermore, various types of rings for hanging can be used, such as hook shapes.

In the drawing, the part near the sewn part of the hanging belt 12 is made to have a sturdy part by, for example, overlapping the belt or sewing and attaching other core material, so that the part of the hanging ring 12 can be made to stand upright. have

Next, the bottom reinforcing bands 14 are sewn diagonally from the four corners of the bottom to near the outlet 4, and the tip of each reinforcing band 14 is shaped like a tube in the width direction, and the tightening rope 15 is passed through the four The bottom reinforcing bands 14 are fastened together.

That is, here, each belt is continuously strung across the upper and lower surfaces of the bag body 1 by the hanging ring belt 1.2, the reinforcing belt 9 of the longitudinal ridge line, the bottom reinforcing belt 14, and the tightening rope 15. When the fork 17 mentioned above is passed through the hanging ring 12 and the bag 1 is suspended, the weight of the bag 1 is evenly distributed on the ring 12 suspended when filling with powder or granules, etc., and the movement of the bag 1 is prevented. becomes easier.

Furthermore, to explain the functions of each part, first, the discharge port 5 on the bottom is stored inside the flap and is closed by the flap, the flap reinforcing band 7, and the tightening string 8, and can be easily removed by untying the tightening string 8. It will be opened in

Furthermore, the bottom surface is reinforced by the flap reinforcing band 7 and its tightening cord 8, as well as the bottom reinforcing band 14 and its tightening rope 15, so that the weight can be supported during filling of powder and granules.

Further, since the injection port 3 on the upper surface has a square sewn portion on the cylinder opening 2, powder particles easily flow in the diagonal direction of the opening, and the corners of the bag body 1 are easily filled during injection.

In addition, ring-shaped hanging hooks 16 made of the same material as the reinforcing bands 9 are sewn at equal intervals to the four reinforcing bands 9 on the top surface, and a fork 17 is passed through the hanging rings 12 to support the bag body 1. If it is stretched, it becomes easier to inject the powder into the bag body 1.

Next, the functions of the trunk reinforcing band 10 and the trunk tightening rope 11 are as described above, but for example, if the unit weight of grains differs depending on the grade, the length of the trunk tightening rope 11 can be adjusted to reduce the overhang of the trunk. Since it is adjustable, bags of the same size can be filled with different grades.

With the configuration described above, even when the bag is filled with powder and granules, the body does not bulge and maintains an almost cubic shape due to the cooperation of each reinforcing band, thereby eliminating wasted space when arranging the bag. Stacking is possible without any problems.

Furthermore, when moving the bag, the suspension ring 12 has a rigid band portion,
By providing the band 13, the band 12 stands upright without bending down at the corner portion of the upper surface, and the fork 17 can be easily passed through this portion, resulting in good workability.

Furthermore, even when suspended, the bag body is less deformed and can be easily moved.

Next, to explain based on an example, Gunny cloth (warp density: 68 threads/10 cm, weft thread density: 32 threads/10 cm, weight per unit area: 660 g/m2) was used as the bag material, and the bag size was 930 mm x 930 mm. mm x 110
The bag had a size of 0 mm (H).

The injection port has a 5QQ mm square opening in the center of the top surface, and is made of Henshan cloth (435g/m2) with a height of 600m.
A 49Q mm diameter opening was provided at the center of the bottom of the discharge port, a 459 mm height tube mouth made of cotton canvas was sewn, and a chrysanthemum-shaped flap was provided for protection.

A nylon belt with a width of 59 mm was sewn to the reinforcing belt, and the same belt was used for the hanging ring.

In addition, a polypropylene belt with a width of 5Q mm was used as the reinforcing band around the torso, and it was sewn to the torso in two places, and a nylon rope (5Q mm) was used.
mmφ) was used for the trunk rope.

Furthermore, there are 8 hooks for hanging with a 20mm wide nylon belt.
We have set up several locations.

First grade rice (
810 g/l) was injected at 1020 kg.

The length of each trunk rope was adjusted to 900 mm.

Measured dimensions after filling: height 1050 mm, top surface 1
It was 150 mm x 1140 mm and maintained a roughly cubic shape, and when it was stacked in two or three tiers of so-called brickwork, stable storage was possible without deformation.

That is, by adopting the configuration of this invention, a large-sized powder storage bag suitable for storage by moving, transporting, and stacking the bag can be obtained.
