Description

[Detailed explanation of the idea] This invention relates to a device for adjusting the internal volume of a powder storage bag.

Conventionally, containers 1 and 6 were used for transporting and storing rice and wheat.
0 kg jute bags and the like were used for transportation and storage in small capacity units.

In recent years, as part of agricultural modernization, intensive production and bulk processing of large quantities have been attempted, and bulk storage in silos has been successfully implemented in some areas, but it requires expensive preparation 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, bags have been constructed using materials with excellent resistance to various types of materials, such as those using so-called cloth containers (flexible containers) and large, stackable bags that are squeezed in the center of the bag. However, the above-mentioned tangible containers are unstable and prone to collapse when directly loaded, so many storage stands are required to securely hold each tangible container, which poses problems in storage space and equipment costs. .

Further, although the above-mentioned stacking type is intended to effectively utilize floor space, the shape is complicated and unstable, so the mold part tends to come loose, resulting in problems in workability, safety, etc.

Furthermore, recently some large-capacity bags formed into flat rectangular shapes are stacked in multiple tiers to make effective use of storage space, but after the contents are filled, the center part bulges out, making it unsuitable for stacking. It is difficult to accurately maintain the flat square shape, and furthermore, it is easily deformed due to movement of the contents.

In addition, the dimensions of a normal bag can be selected depending on conditions such as the truck bed size, the size of the storage area, the content capacity, and workability, but the dimensional weight (g
/l) was different, so it could not be an optimal bag.

For example, the quality of the contents of grains, etc. varies depending on the grain, variety, brand, etc., and is graded according to the classification.For ordinary wheat, the first grade is 770 g/l, the non-grade is 650 g/l,
For paddy rice brown rice, the first grade is 810g/l, and the non-grade rice is 77g/l.
There is a big difference between 0g/l and 0g/l.

In this way, the volumetric weight (g/l) differs depending on the grade, so in order to set and prepare the bag dimensions for each volume type,
This is currently not possible as it would require a very large number of individual loads and would be uneconomical.

In order to eliminate such drawbacks, this invention has a bag function with variable internal volume suitable for each class with different volumetric weight, and has a bag function that can be moved,
We would like to propose a device for adjusting the internal volume of powder storage bags, which is highly effective in stacking operations, transportation, etc.

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

As shown in Fig. 1, a flat square shape is made using a flexible bag material 4a such as hemp, a hanging ring 1 is attached to the ridgeline around the flat square shape, and a hanging ring 1 is attached to the central part of the front face 2. In a powder storage bag 4 having an entrance/exit 3, one end of a rope 5 is fixed to a lower surface 6 of the bag, and the other end is tightened externally through a bag base 4a on an opposing upper surface 7 so that the length of the rope can be adjusted freely. Load adjusters 8 are provided at regular intervals in the longitudinal direction of the bag.

The internal volume adjuster 8 is intended to adjust the capacity inside the bag and maintain the flat rectangular shape. is suitable for strength.

The tightening part on the top surface 7 may be anything that can temporarily fix the rope 5. For example, as shown in FIGS. , an elliptical plate 13 having a rope support hole 11 and a fixing hole 12
is provided, and the studs 14 are passed through the fixing holes 12 of this elliptical plate 13,
The lower end is caulked and riveted to the top surface 7 of the bag, and the free end of the rope 5 is passed through this elliptical plate 13 and tightened, and the length of the rope interposed in the bag is adjusted by tightening and loosening this part. The free □ end of the rope 5 is taken out to the outside of the bag via a retaining ring 15 which is fixed to the base material 4a and the reinforcing band 9.
The rope is passed through the rope center hole 10 of the oval plate, then passed through the rope support hole 11, and then passed through the rope center hole 10 again to be tightened.

,. In addition, the rope fixing part on the bottom surface of the bag may be one that is not bulky so that the contents inside the bag do not leak to the outside and does not hinder the internal movement of the contents. Same retaining ring 1
Fix two ropes 5 parallel to each other, take out one end of the rope 5 to the outside through one of the retaining rings 1.5, and then fix the two ropes aligned inside through the other retaining ring 15. The metal fittings 16 are used to firmly slide on and off.

Also, it is natural to provide the necessary number of internal volume adjusting devices 8 depending on the size of the bag, but if the contents are about 1 ton, it is appropriate to arrange them in parallel at two locations in the longitudinal direction of the bag. There is.

Now, if a bag equipped with the internal volume adjusting device of this invention is used, the bag material will swell and the center of the upper and lower surfaces will bulge out after filling the contents.1. However, the upper and lower surfaces 7, 6 are adjusted by means of inner volume adjusting tools 8 arranged at regular intervals in this central part.
Since the gaps are connected to a certain length so that the inner volume is set in advance, the bags are suitable for the contents even though they have the same size.

For example, when it comes to grains, you can determine in advance the opening and rope length that will be the appropriate bag size for each type of tree or wheat, and if you later want to store grains of different dimensional weights, you can use the pre-determined rope length settings. If the adjustment is made based on the above, the flat square shape having a predetermined internal volume can be maintained at all times without changing the shape of the ridgeline portion of the bag by simply increasing or decreasing the distance between the upper and lower surfaces 7 and 6 of the bag.

In this way, by appropriately adjusting the length of the rope 5 of the internal volume adjuster 8, it is possible to change the internal volume, so that the contents are uniformly dispersed in the bag and deformed. The flat square shape can be held accurately without fear.

Therefore, it has an ideal shape for stacking, making stacking operations easy, and after stacking, the contact area between the top and bottom surfaces is wide and stable, making it not only ideal for multi-level stacking, but also
No more wasted storage space.

The filling operation of rice, wheat, etc. can be carried out by suspending the hanging ring on the front side 2 and injecting from the pouring inlet 3 located at the upper end, and the discharging operation can be carried out by suspending the hanging ring on the back side 17 and pouring from the pouring inlet 3 located at the upper end. The liquid can be discharged by opening the spouting port 3 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] 4. On the bag base,
Using gunny cloth as the base fabric, dimension 2000 mm
, x 1000 m4
Form a cylindrical pouring inlet of 0 mmφ x 500 mm,
In addition, reinforcing bands are sewn at regular intervals along each ridgeline and the periphery of the flat square bag, hanging rings are placed around the periphery, and an inner volume adjusting device with a 5 mm diameter nylon rope is attached to the center of the top and bottom sides of the bag. A storage bag for storing rice and wheat with good ventilation was made by arranging two leather rows in the longitudinal direction.

The length of the rope is 460m depending on the contents to be filled.
It was set to m.

, and the shellfish? 1050k of 3rd grade wheat in storage bag
When filled with 1.5 g (volumetric weight: 690 g/l), the ridgeline part was sufficiently tensed and a flat square shape most suitable for multi-level stacking was obtained. Not only was this possible, but an extremely stable loading condition was achieved with no room for the cargo to collapse, confirming safe stacking.

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

From Table 1 above, this invention can greatly save labor,
Furthermore, it can be seen that work efficiency can be significantly improved.
