Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting bag for transportation and a method for unpacking the same, and in particular, is constructed by knitting a string-shaped member such as polypropylene (PP) or other synthetic resin material to transport and produce agricultural products. The present invention relates to a transportable knitted bag that can be stored and a method of unpacking the knitted bag.

[0002]

2. Description of the Related Art Conventionally, various agricultural products such as rice,
Granular products such as wheat, beans, corn, coffee, etc., flour, crushed corn core (corn cob meal) and other powdery products, or specially shaped agricultural products such as soybean hulls and hay cubes, and livestock feed, Various transport bags are used for transporting granular materials such as plastic pellets and other various materials. As described below, as described below, a knitting bag for transport, which is formed by knitting a flat and elongated cord-like member due to demands of not only toughness and strength but also transportability or workability, as well as air permeability, is generally used. It is a target.

[0003] A conventional knitting bag 1 for transportation will be outlined with reference to Figs. FIG. 8 is a plan view of the knitting bag 1 for transportation. The knitting bag 1 for transportation is formed by knitting a thin, flat and elongated cord-like member 2 into, for example, vertical and horizontal stitches to form a bag main body 3, and one end thereof. Is closed by a bottom string material 4 to form a bottom end 5, and the other open end is provided as a storage opening 6. The string-shaped member 2 is made of a synthetic resin material such as polypropylene (PP). Agricultural products (for example, corn cob meal 7) are received from the storage opening 6, closed with a closing cord 8 (indicated by a virtual line in the figure), and transported to a predetermined destination. Alternatively, it is temporarily stored in a warehouse or the like as needed.

[0004] By the way, especially for imported agricultural products,
Since the plants must be inspected at the port in Japan, the knitting bags for transportation are stored at overseas loading sites, either during storage in a warehouse or in a container loaded with the knitting bags for transportation 1 using a fumigant. Insects and pests are killed by fumigation with vaporized gas. In such fumigation treatment, a packaging form that conforms to imported plant quarantine standards is required in order to obtain an appropriate fumigation effect specified by law. That is, as described above, the knitting bag 1 for transportation has a thickness of several tens to several hundreds of microns, and is formed by ventilating a very thin (for example, about 2 to 5 mm in width), for example, a flat polypropylene thread or string-like member. In order to ensure that the fumigation gas permeates the necessary and sufficient internal agricultural products, the ventilation standard is secured.

[0005] In addition, the worker stabs and lifts the knitting bag 1 for transport with his / her hand hook, and handles it. There is also an advantage that the hole once opened by the hook is naturally repaired, and the stored contents do not leak.

FIG. 9 is a schematic perspective view of a portion of a bag opening device 10 for supplying corn cob meal 7 contained in a knitting bag 1 for transportation to a material input port 9 in a factory or the like. With the transported knitting bag 1 fixed from the left and right by the sharp fixing rod member 12, the unpacking blade 13 rotating at the center thereof
, And one surface (bottom surface) of the knitting bag 1 for transportation is cut open by the unpacking blade 13 and the corn cob meal 7 is dropped to the raw material inlet 9 by gravity.

However, when the knitting bag 1 for transport is cut by the unpacking blade 13, the flat and thin cord-like member 2 is cut and separated from the bag main body 3, and the long and thin pieces 2 A are put into the raw material inlet 9 together with the corn cob meal 7. It may be done. That is, the pieces 2A of the string-shaped member 2 are supplied to various production facilities together with the raw materials. The transport knitting bag 1 packed with the corn cob meal 7 is not completely fixed and is not a completely rigid body. Since the impact from the meal 7 is also applied, the elongated piece 2A of the string-shaped member 2 is easily generated.

As a matter of course, without using the bag opening apparatus 10, the transport knitting bag 1 is cut by hand with a knife or a cutter, for example, along the side surface, the bottom end 5 or the vicinity of the accommodation opening 6 in the vicinity thereof. It is difficult to prevent the generation of the piece 2A even when the bag is opened in a short time or in a straight line. In addition, since the worker's body may be injured accidentally during the cutting operation, the above-described bag opening device 10 or the like may be used in terms of work efficiency and safety. There is no change in that it is difficult to prevent the generation of the section 2A. In addition, the knitting bag 1 for transportation is formed by knitting the string-like members 2 vertically and horizontally according to the shape of the bag main body 3 in view of cost, easiness or rationality in manufacturing the product, and stability when the contents are contained. When the bag is cut and opened along the central portion, the side surface, the bottom end portion 5 or the housing opening 6 as described above, the elongated piece 2A tends to come out as described above. Even if the cord-like member 2 has a knitting form in which the cord-like member 2 is obliquely knitted, it is difficult to prevent the generation of the piece 2A depending on the cutting mode. In addition, there is also a method of opening the storage opening 6 by unwinding the closing cord material 8 and opening the bag, but from the viewpoint of workability, the above-described machine or manual cutting and opening operation is performed. There are many.

More specifically, for example, as shown in FIG. 10, corn cob meal 7 is filled in a cultivation container 14 as a raw material for mushroom cultivation, and is used as a medium for mushrooms 15 and the like. However, as shown in FIG. 9, it is inevitable that a large number of pieces 2A of the string member 2 made of synthetic resin such as polypropylene are mixed during the unpacking operation of the knitting bag 1 for transport. Since the section 2A does not spontaneously decompose, there are the following problems.

[0010] As shown in FIG. 10, the fact that the cut pieces 2A of the string-shaped member 2 are mixed in the culture medium such as the mushroom 15 is not so problematic for the cultivation of the mushroom 15 itself.
If the piece 2A may enter the mushroom 15 itself with the growth of the product (of course, the presence or absence of these pieces 2A is inspected at the time of product shipment), the value of the product as well as the labor of the inspection and its response is increased. Not only lowers food safety.

Further, after cultivation and harvesting of the mushroom 15, it is necessary to reuse the medium such as corn cob meal 7 as a material for soil compost, or to mechanically dry and reuse it as feed for cattle and other livestock. Proposed. That is, in addition to the recent environmental protection problem, there is a problem that if the pieces 2A that are not reduced to the soil and are mixed into the compost due to the regulation by the Waste Recycling Law become obstacles to reuse. Further, when a medium such as corn cob meal 7 is supplied as feed for livestock or the like, fine slices 2
There is a problem that A may adversely affect the health of the fed livestock. Needless to say, if a removing device (not shown) for removing the pieces 2A from the corn cob meal 7 is provided, the above-mentioned problems can be solved. However, when the removing device is expensive, the cost increases. There's a problem.

The influence of the mixing of the cut pieces 2A into the material on the product itself and various problems in the subsequent reuse are not limited to the corn cob meal 7, but may be in the form of powder, granules, or solids having a predetermined size. Nevertheless, other agricultural products and various supplies are also likely to be generated, and some solution was requested.

[0013]

The second invention is a method for unpacking a knitting bag for transportation capable of forming a bag body by knitting an elongated cord-like member and accommodating materials such as agricultural products inside the bag body. ,
In a part of the surface of the bag body, a covering material is provided so as to be integral with the string-shaped member at a portion over a predetermined area to form a cutting region for unpacking, and the string-like member and A method for unpacking a knitting bag for transport, characterized in that the bag body can be unpacked by cutting the covering material.

The string-like member is made of a synthetic resin material such as polypropylene, and the coating material can be laminated and coated on the string-like member made of the synthetic resin material.

As the covering material, the same kind of material (for example, polypropylene) as the material of the cord-like member can be used. That is, the integration of the covering material and the cord-like member can be reliably ensured.

As the covering material, a material different from the material of the cord-like member (for example, polyethylene for the polypropylene of the cord-like member) can be used. That is, by adopting different types of materials, it is possible to make a knitting bag for transportation utilizing characteristics of each material in accordance with agricultural products or the like, a bag opening device and other various conditions.

The cutting area for unpacking can have a different color from the color of the bag body. That is, the bag body is generally white, which is the color of the string-shaped member, but the covering material for the cutting region for unpacking can be specified as, for example, blue, red, or the like, to clearly indicate the region for unpacking.

The cutting region for unpacking can be formed on one of the surfaces of the bag body.

[0030]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a knitting bag 20 for transportation and a method for unpacking the same according to an embodiment of the present invention will be described with reference to FIGS.
It will be explained based on the following. However, the same parts as those in FIGS. 8 to 10 are denoted by the same reference numerals, and detailed description thereof will be omitted. FIG. 1 is a plan view of a transport knitting bag 20, and FIG.
FIG. 2 is a cross-sectional view taken along the line II-II of FIG.
The bag body 3 formed by the string-like member 2 and a cutting area 21 for unpacking formed at a predetermined width and the same length as the bag body 3 at a part of one surface of the bag body 3, for example, at the center thereof.
And

The cutting area 21 for unpacking is made of a covering material made of a synthetic resin material such as polypropylene, which is the same as the material of the cord-like member 2, and a part of the surface of the cord-like member 2 over a predetermined area. A coating material is laminated and coated with a predetermined thickness that can be integrated with the cord-like member 2. The cutting area 21 for unpacking secures the ventilation area as the bag body 3 in addition to the cutting area 21 for unpacking, and the string-shaped member 2
And the covering material of the cutting area 21 for unpacking together (simultaneously)
The bag body 3 can be opened by cutting.

In the illustrated example, the length and width of the elongate rectangular opening / closing cutting area 21 can be arbitrarily designed. It is desirable to form the bag body 3 wide so that the cutting range can be formed in the width direction with a margin, and narrower to maintain the air permeability better. About 10 to 70% of the width, generally about 20 to 60%, preferably 30 to 5
0%.

The place where the cutting area 21 for unpacking is formed is arbitrary depending on the configuration of the unpacking apparatus 10 and the like, but it is sufficient if this is formed on a part of one surface of the bag body 3. .

When the bag cutting area 21 is to be manually dismantled, it can be formed in any direction along the side surface, the bottom end, the housing opening, or any other direction. Generally, it is desirable that the knitting bag 20 is formed along the cutting direction or the conveying direction (for example, the longitudinal direction) of the transporting knitted bag 20 in the bag opening device 10 or the like (FIG. 9).

The color of the bag-cutting area 21 is, for example, blue, and is different from the color of the bag body 3 (usually white), so that the cut portion can be identified. Of course, the type of agricultural product or material to be stored may be distinguishable by this color.

FIG. 3 is a perspective view showing a state in which the corn cob meal 7 is accommodated in the knitting bag 20 for transportation. The storage opening 6 is closed to enable handling, transportation and storage.

FIGS. 4 and 5 show the knitting bag 20 for transportation.
FIG. 4 is a schematic side view of a laminating coating process, and FIG. 5 is a diagram illustrating sewing of a bottom string material 4 and separation and cutting of a bottom end portion 5 and a housing opening 6. FIG. 4 is a perspective explanatory view of the process. First, as shown in FIG. 4, a coating material 24 made of polypropylene or the like melted from a hopper 23 is applied to a cylindrical bag material 22 formed by knitting an elongated cord-like member 2 to a predetermined width. , And if necessary, it is spread by a roller 25 and cooled to a predetermined thickness. In this manner, lamination coating is performed to form a cutting area 21 for unpacking, and the knitted bag material 26 is wound into a roll. As shown in FIG. 5, the roll-shaped knitting bag material 26 is pulled out, the bottom cord material 4 is sewn with the portion having a predetermined length as the bottom end portion 5, and cut and separated to form the knitting bag 20 for transportation. .

The coating material 2 which is the material of the cutting area 21 for unpacking
As the four types, any combination can be adopted according to materials such as agricultural products, the bag opening device 10 and other various conditions, the material of the string-shaped member 2, and the like. By using the same type of material as the material of the cord-like member 2, for example, polypropylene, as the covering material 24, it is ensured that the covering material 24 and the cord-like member 2 are integrated, and it is completely integrated with the cord-like member 2. The cutting region 21 for unpacking can be formed as a sheet-like member. In general, in consideration of various treatments or recycling by processing or recycling of the transporting knitted bag 20 after unpacking, it is desirable that the material is the same as that of the string-shaped member 2.
In order to obtain the required characteristics, the cutting area 21 for unpacking (covering material 2
4) It is possible to arbitrarily select the material of the string-shaped member 2. For example, if the covering material 24 is made of a material different from the material of the cord-like member 2, such as polyethylene having excellent impact resistance, the impact-resistance of the cord-like member 2 in the cutting area 21 for unpacking at the time of cutting is reduced. Can be improved.

In order to accommodate the corn cob meal 7 in the knitting bag 20 for transport having such a configuration, transport the corn cob meal 7 to the factory, and unpack the corn cob meal 7, a cutting opening area 21 may be opened. FIG. 6 is a cross-sectional view of a main part of the unpacking apparatus 10 (FIG. 9), and FIG. 7 is a cross-sectional view of the main part from the cutting direction, as shown in FIG. The knitting bag 20 for transport is placed on the carrier 11 so that it faces upward on the carrier 11, and the portion of the cutting area 21 for unpacking is cut by the rotating bag-blading blade 13 to open the bag. In addition, since the cutting area 21 for unpacking is different from the white bag main body 3 and is, for example, blue, the operator identifies the cutting site and sets the cutting area 21 for blue unpacking on the lower side of the transfer table 11. A transport knitting bag 20 can be placed thereon. In addition, if the unpacking cutting regions 21 are formed on both sides of the bag body 3, the unpacking cutting regions 21 on either one of the surfaces may be cut, and the transport knitting bag 20 is placed on the carrier 11. The workability at the time of placing can be improved.

As shown in FIG. 7, by opening the cutting area 21 for opening the bag, the cutting area 21 for opening the bag is separated to the left and right, and an opening 27 is formed in the bag body 3 so that the corn cob meal 7 can be cut. It falls to the raw material inlet 9 by its own weight. Thus, the string-shaped member 2
Is integrated with the covering member 24 in a sheet shape, so that the string-shaped member 2 can form the necessary opening 27 without generating the elongated piece 2A even by the cutting operation by the bag-opening blade 13. Therefore, it is possible to prevent the pieces 2A from being mixed into the corn cob meal 7 with the unpacking operation of the knitting bag 20 for transport, and not only to the various food manufacturing processes but also to the reuse process as compost or livestock feed. The above-mentioned problems caused by the piece 2A in the processing step (1) can be avoided.

[0041]

As described above, according to the present invention, a cutting area for unpacking is formed in a part of a bag body knitted with a string member, and the cutting area for unsealing with the string member is formed. Since the parts were cut and opened, the mixing of the pieces of the string-like member accompanying the opening of the bags was prevented, and in the processing and reuse of corn cob meal and other agricultural products,
It is possible to solve various problems such as the incorporation of non-reducible synthetic resin materials into food and other products, compost and feed for livestock.
