Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is a bag for transporting heavy objects (hereinafter referred to as a bag for carrying heavy objects, which is suitable for carrying large amounts of metals, minerals, grains, and other various lumps, particles, and powders. Simply called a bag for heavy goods).

[0002]

2. Description of the Related Art Conventional heavy goods bags have been made of mere woven cloth, rubberized cloth, polypropylene fiber folded cloth, tape yarn, or the like, as one example of a container bag.

[0003]

The conventional container bag as described above can store only about 1 to 3 tons of contents. The strength must be increased, and as long as a normal knitted fabric is used as the material, an increase in the storage capacity cannot be expected so much. Therefore, in order to measure the increase in strength, rubberized cloth is used or a knitted fabric is used. Some polypropylene fibers are mixed or tape woven fabrics are used, but these increase the price and increase the weight of the items to be stored, but increase the weight of the container bag. Due to the drawbacks of large size and easy cracking of the constituent tape yarns, this device can be stored much more than the increase in the weight of the heavy bag. It is an object to increase the weight of providing container bag acceptable.

[0004]

In order to solve the above-mentioned problems, the present invention uses a belt-shaped or tape-shaped strip 1 made by weaving chemical fibers or synthetic fibers to make a heavy-weight bag body 2 into a basket shape. It is a heavy-duty bag for transporting heavy goods.

In the bag for heavy goods according to the present invention, a part of the strip 1 constituting the bag body for heavy goods 2 may project from the bag body for heavy goods 2 to form a lifting belt.

In the heavy-duty bag according to the present invention, the strip 1 on the upper portion of the heavy-duty bag body 2 is the same as or separate from the strip 1 constituting the heavy-duty bag body 2. The strip 1 may be inserted to form the lifting belt 3.

In the bag for heavy goods according to the present invention, it is preferable that a lid piece 4 such as a net or cloth is attached to the upper part of the main body 2 for heavy goods as required.

The heavy-duty bag body 2 of the heavy-duty bag according to the present invention has a bottom portion and four circumferential portions integrally formed by braiding a plurality of strip-shaped pieces in a basket shape. .

The shape of the strip 1 used in the present invention may be referred to as a belt or a tape, which is, for example, 3 to.
Those having a width of about 5 mm to 50 mm or about 100 mm are used.

The weight of the heavy-duty bag according to the present invention can be stored in the range of several tens of kilograms to 2 to 3 tons, which is not appropriate in view of the price of the heavy-duty bag, and it is considered that it is difficult to store it at present. 5 to 10 tons of goods can be stored.

[0011]

[Operation] In order to increase the weight of the goods stored in the bag for heavy goods, the strength of the bag for heavy goods must be increased. Therefore, in this invention, weaving chemical or synthetic fibers is used. By using a belt-shaped or tape-shaped strip, the strength as a material for a bag for heavy goods is dramatically increased, and a bag for heavy goods is formed by knitting a large number of these strips in a basket shape. Since the bottom part and the four-round part are formed continuously, the structural strength is remarkably increased.

[Examples] FIG. 1 is a side view of a heavy goods bag according to an embodiment of the present invention, FIG. 2 is a plan view of a heavy goods bag body, and FIG. 3 is a lifting belt attached to the heavy goods bag body. It is a side view of the important section of the bag body for heavy goods which shows an example. In the figure, reference numeral 1 denotes a strip-like piece, which is a belt-like or tape-like piece formed by weaving chemical fibers or synthetic fibers. The strip 1 is a belt or tape formed by knitting or weaving chemical fibers or synthetic fibers, and has a width of, for example, about 3 to 5 mm to 100.
The width is about mm or more, and the thickness is also arbitrary. With this strip 1, the bag body 2 for heavy goods
, But for that purpose, with a large number of strips 1,
Knitting is performed in the same manner as knitting a basket, which makes it possible to form a basket or a bag even though there is no clear boundary between the bottom of the heavy bag body 2 and the four circumferences. It is said that That is, in the conventional one, the bottom piece and the four-sided piece are joined by sewing or other means, but in the present invention, they are joined by means such as sewing. Absent. The bag body 2 for heavy objects is hoisted by the hoisting belt 3, and the hoisting belt 3 may be the same as the belt-shaped piece 1 or may be another one. In order to provide the lifting belt 3 on the heavy-weight bag main body 2, as shown in FIG. 1, a strip-shaped piece 1 which constitutes the heavy-weight bag main body 2 is particularly long and is longer than other strip-shaped pieces. The bag body 2 for knitting is knitted and then extended from the bag body 2 for heavy goods to form the lifting belt 3. In addition to this, as shown in FIG. 3, the upper end of the bag body 2 for heavy goods is knitted. The belt-shaped piece 1 mentioned above is slightly loosened, and the lifting belt 3 is inserted through the band-shaped piece 1. Reference numeral 4 is a lid piece, which is preferably covered with a net or cloth to cover the bag body 2 for heavy goods.

[0013]

The bag for heavy goods according to the present invention is made of a chemical fiber or a synthetic fiber, and is made of a belt-shaped or tape-shaped strip formed by weaving the synthetic fiber. Since the body of the heavy goods bag is woven into a basket, it has extremely high strength, and the weight of the heavy goods bag body is heavier than conventional container bags, but the storage capacity is dramatic. However, the present invention can store only 5 to 10 tons or more, while the conventional apparatus can store only 1 to 3 tons. This is because in addition to the strip made of chemical fiber or synthetic fiber, the bag body for heavy goods is knitted in a basket shape with a large number of these strips. This is because the heavy-duty bag body is made up of a single piece instead of the cloth pieces that are joined and integrated by sewing or other means, and thus the weak point for strength is eliminated.
