Description

[Detailed explanation of the idea] This invention relates to an improvement of a powder storage bag.

Conventionally, 60 containers were used for transporting and storing rice and wheat.
9 Cannabis bags, etc. were used for transportation and storage in small capacity units.

By the way, in recent years, as part of agricultural modernization, intensive production and bulk processing have been attempted, and bulk storage in silos etc. has been implemented in some cases, but this requires expensive equipment costs and
This was difficult to implement given the scale of farming in Japan.

In addition, for mass transportation of rice, wheat, powder, etc.
Conventionally, various types of bags have been proposed, such as those using so-called flexible containers (flexible containers) whose bodies are made of materials with excellent resistance, and large, stackable bags that are squeezed in the center of the bag. However, the above-mentioned living containers are unstable and prone to grooves when directly loaded, so many storage stands are required to securely hold each living container, which poses problems in terms of storage space and equipment costs.

Further, although the above-mentioned stacking type is designed to effectively utilize floor space, it has a complicated and unstable shape, so it easily loses its shape and has problems with workability, safety, etc.

In order to eliminate such drawbacks, this invention proposes a powder storage bag that is highly effective in filling and discharging bags, moving the bags, transporting the bags, etc., and is also economical.

An embodiment of this invention will be described below with reference to the drawings.

As shown in Figure 1, a flat rectangular bag is made from a flexible material such as hemp, and highly durable reinforcing bands 1a such as nylon are sewn to the four ridges in the longitudinal direction. direction, each ridge line in the vertical direction, the flat square top and bottom surfaces 2, 3, and both side surfaces 4,
Ordinary reinforcing bands 1b made of polypropylene or the like are sewn at regular intervals in the vertical and horizontal directions of 4 and diagonally on the front 5 and back 6.

Furthermore, hanging rings 7 are attached to the four corners of this flat square upper surface 2 and the intersections of the reinforcing bands on both of their longitudinal ridge lines, and the reinforcing bands on the four corners of the front face 5 and back face 6 and on both of their longitudinal ridge lines are attached. A hanging ring 7 is attached to the intersection, and a cylindrical spout 8 is installed at the center of the front 5.
A powder storage bag 9 having a protruding structure is constructed.

In order to maintain the distance between the upper and lower surfaces 2 and 3 of the submale approximately equal to the thickness of the bag, a reinforcing band 1 is provided in the width direction of the upper and lower surfaces 2 and 3.
A plurality of connecting ropes 10 are tied between b and lb.

The reason why the powder storage bag 9 is made into a flat rectangular shape is because it is the most suitable shape for stacking in multiple stages after filling.

In addition, when the powder storage bag 9 is moved on a suspension support, the highly durable reinforcing band 1a is used only for the parts that are subjected to a particularly large load, and the normal reinforcing band 1b is used for the other parts. did.

This is because, in addition to the large number of reinforcing bands required per bag, the number of bags used in general during mass transportation and storage is large, so we use the cheapest ordinary reinforcing bands as much as possible. It was constructed using

If the powder storage bag of this invention is used, the flexible material will swell up after filling to form a flat square bag.When moving this bag to a predetermined position, the hanging rings 7 on both sides of the top surface should be directly attached to the forklift, etc. It can be easily transported by inserting a fork or by suspending it from a forklift using a rope connecting the hooks attached to the hanging rings on both sides.

In addition, after filling with rice, wheat, etc., it becomes a flat rectangular shape, which is an ideal shape for stacking, making stacking operations easy. Not only is it ideal for stacking, but it also eliminates wasted storage space.

In addition, the filling operation of rice, wheat, etc. can be carried out by suspending the hanging ring on the front side 5 and pouring from the spouting port 8 located at the upper end, and the discharging operation can be carried out by suspending the hanging ring on the back side 6 and pouring from the lower end. The liquid can be discharged by opening the spouting port 8 located at .

Furthermore, when not in use, it goes without saying that since the bag material is flexible, it can be folded to make it smaller.

〔Example〕

Gunny cloth warp density 68/10σ, weft density 32EE/10cm, mass per unit area 6601 on bag base
/rd as the base fabric, dimensions 2000mm x 10
Make a flat square bag measuring 00mm
It features 50 cylindrical spout openings, and highly durable reinforcing bands of nylon tape fabric 5o1rrrrL width are sewn on four sides of the longitudinal ridgeline, and other polypropylene tape knitted fabrics 53 mm wide are sewn. I sewed on an inexpensive reinforcing band.

In addition, there are 20 suspension rings in total, 8 on the top and 6 on the front and back, and in the center of the top and bottom, connecting ropes are placed in parallel in two locations in the longitudinal direction. I made a good storage bag for rice and wheat.

When this storage bag was filled with 1050 kg of 3rd grade wheat (volume weight 690 g/f), the ridgeline part became sufficiently tense and a flat rectangular shape most suitable for multi-tiered stacking was obtained, which was further stacked into 8 tiers. As a result, not only was it easy to stack, but an extremely stable loading condition was obtained with no room for groove wrinkles, and safe stacking was confirmed.

Next, Table 1 shows the results of comparing the work efficiency of this invention and the conventional 60 kg jute bag.

Table 1 (Throughput amount: 100 tons) From Table 1 above, this invention can significantly save labor.
Furthermore, it can be seen that work efficiency can be significantly improved.
