Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for removably packing the entire circumference of a coiled object while leaving a space around the inner periphery of the coiled object, and a cover for the packaging. .

In the present invention, a coiled object refers to an object having a space-like inner periphery with a doughnut-shaped cross-section after winding up the material, and the material thereof is, for example, metal, paper, resin, or the like. The shape may be, for example, linear, band-like, thread-like, or irregularly shaped, and is not particularly limited, but in the following, for convenience of explanation, the present invention will be described using a steel wire rod coil used in the iron and steel industry as a representative example.

In other words, the present invention aims to provide a packaging method that achieves at least one or more of the following in logistics processes such as transportation, handling, and storage of wire coils, and a cover used for the packaging. . (Non-ranking) ■Being able to suppress or prevent the occurrence of scratches, ■Being able to suppress or prevent deformation of the coil shape (package collapse), ■Being able to suppress or waterproof the ingress of rain and water into the coil, ■Being able to prevent the formation of dew condensation on the coil. ■It is possible to suppress or prevent the occurrence of rust, wetting, etc. on the coil, ■It is possible to handle and transport cargo even in rainy weather, ■It can be used as a simple storage, ■It has good packaging workability. (Simplicity, speed, reliability, etc.) ■The packaging cover must be lightweight and easy to handle; [Aspect] It must be able to be used repeatedly for packaging (durability); ■It must be inexpensive.

[Prior Art] There have been several proposals for packaging wire coils. For example, in Fig. 14, Utility Model Publication No. 57-5516li "Wire Rod Coil Packaging", the wire coil 28 is provided with quality information and a cushioning material 29, which is lower in hardness than the wire coil, is attached to only one side with a wire 30. It is. This is definitely &l shock material 2
9 is functional and has the practicality of preventing the occurrence of scratches during transportation, which is the intended purpose. However, since the wire coil 28 is exposed, for example, it cannot suppress or prevent water intrusion, it cannot suppress or prevent the occurrence of dew condensation (corrosion cannot be prevented), it cannot be used for cargo handling in rainy weather, and it cannot be used as a simple storage. There are problems such as not being able to do it.

Also, in Figure 15 (a) and (r1), there are
No. 7 "Wire rod coil packing method and packing cloth J is shown. In this, the wire rod coil is packed with 3 liters of packing cloth, but the space-shaped inner periphery 32 of the wire rod coil is not packed at all. Similar to No. 57-55166, there are problems such as inability to suppress or prevent water intrusion, inability to suppress or prevent the occurrence of dew condensation (cannot prevent rust), inability to handle cargo in rainy weather, and inability to use as a simple storage. JP-A No. 62-18427 specifies that the material of the packaging cloth is made of synthetic fiber cloth, so there is a limit to how much the used packaging cloth can be recovered and used repeatedly, and it lacks durability.
In the end, there is also the drawback of high costs.

Furthermore, in Utility Model Application Publication No. 61-161281, the 16th
As shown in the figure, a packing cloth 37 is disclosed which is inserted into the space-like inner periphery of a wire coil 36 and wraps the coil by folding back the excess portions on both sides. However, in this example, it is necessary to pack or unpack the coil in a suspended state, which poses problems in terms of workability and labor-saving.Furthermore, there is no consideration given to rain or water intrusion, so there is no need to prevent condensation or prevent it. It was also unsatisfactory in terms of rust resistance.

Therefore, the current methods of packaging wire rod coils are at the level of ideas or technology that suppress or prevent the occurrence of flaws on the outer periphery of wire rod coils during the distribution process, or improve packaging workability.

As seen in many publicly known examples, it is not clear why the inner circumferential space of the wire coil is not packaged, but the inventors have developed a new packing method and packing cover. I analyzed it as follows.

(Uneven ranking) a. Packaging poses a hindrance to cargo handling, costs, and more.

b. Quality control requirements for wire rod coils were not as strict as they are today.

C. The handling of wire rod coils is affected by rain (weather), but even if it were affected, until today, the logistics management from production to shipping to delivery was not strict.d. There is no quality control system in place that takes into account the management (storage) of wire coils in the customer's yard.

C. The space around the inner periphery of a wire rod coil is created when converging during the wire production process, but there are many opportunities to effectively utilize the space around the inner periphery during cargo handling later in the logistics process. The development of packaging methods related to space is
It seems like it has become a taboo among those skilled in the art.

f. When considering quality maintenance of wire rod coils during inventory management, even if the development of quality control technology for each warehouse is considered, quality maintenance technology for each wire rod coil unit, such as prevention of dew condensation, prevention of rust, etc. , I can't find any ideas to prevent contact with water during outdoor storage (commonly referred to as outdoor storage, storage at a customer's site, or storage in a garden).

g. In order to prevent (including suppress) the occurrence of rust, loading and unloading of wire rod coils will be suspended in the event of rain. As a solution to this
Although the idea of investing a large amount of money in cargo handling facilities that enable cargo handling in the rain is seen, the idea of rainy weather cargo handling measures for each wire coil unit is
Even though I am a person skilled in the art, I have never heard of such a case.

These a-g are made of special materials even if they are coil-shaped.
Or, items made of expensive materials are packed using oiled paper, cloth, wooden crates, or other materials, but there are no packaging methods or packaging covers that fully consider the labor-saving aspects of logistics and cargo handling. In other words, for example, at least one worker packs, handles,
There are no packaging covers that can be used repeatedly for packaging, such as disassembling the packaging, reducing the volume of the disassembled packaging cover, handling and transporting it, and using it again for the next packaging. There were many voices eagerly awaiting its provision and appearance.

[Problems to be Solved by the Invention] By the way, considering the mechanism by which rust occurs, rust on steel is generated based on the following equation due to the coexistence of water and oxygen in the atmosphere.

The wire coil has a mill scale layer on the surface of the wire [when looking at the mill scale in cross section, when the temperature is 575°C or higher, Fe203 on the outside and Fe30 in the middle. , exhibits a triple layer of FeO on the inside (the side in contact with the surface of the H material)], but this mill scale has a small elongation compared to the coefficient of linear expansion of Fe in the wire, so this difference in elongation is one of the important factors. The water becomes trapped and cracks occur, and the above water infiltrates through these cracks, destroying the Fe of the wire.
Rust occurs when it comes into contact with. This water means rainwater or moisture due to condensation. In this case, rusting is related to relative temperature, and rusting rapidly progresses from around 60 to 70 tons of relative temperature. (Refer to Figure 12, relationship between relative temperature and dispatch.) On the other hand, the above dew condensation occurs even when the wire coil is stored in a warehouse.
room temperature) and dew point temperature (see Figure 13).

1) Condensation on wire coil = wire coil temperature ≦ dew point temperature 2)
Warehouse ceiling dew condensation = attic temperature ≦ dew point temperature Therefore, in order to suppress or prevent rust formation, it is necessary to focus on rust formation and dew condensation and consider countermeasures from these perspectives.

1》Measures to suppress or prevent rust (1) Prevent wire coils from coming into contact with rain, water, and oxygen.

(2> Store at a relative temperature of 601 or below.

2) Concept of measures to suppress or prevent condensation (1) Suppress or prevent condensation on II material coil ■Always keep the temperature of the wire coil higher than the dew point.

■Dehumidification (lowering the dew point temperature by reducing the amount of water vapor) <<2> Suppression or prevention of condensation on the warehouse ceiling ■Always keep the attic temperature higher than the dew point.

■Dehumidification (lowering the dew point temperature by reducing the amount of water vapor) However, in order to thoroughly prevent condensation on warehouse ceilings as described above, not only would a huge amount of capital investment be required, but even if the investment were made, the physical conditions For example, it is difficult to maintain and manage temperature, humidity, pressure, etc., so even if it is possible to do so theoretically, it is difficult to realize it.

Therefore, the inventors of the present invention have taken measures that can be implemented easily, such as measures against rust and dew condensation in each wire coil, prevention of defects and deformation of the coil, packaging with good workability, disassembly, and other technical issues that will be listed later. We attempted to develop a packaging method and packaging cover that could achieve this goal.

In view of the current situation, the present invention was developed with a focus on packaging a wire coil in such a way that the entire circumference of the wire coil can be removed while leaving a space around the inner circumference of the wire coil, which has not been thought of in the past. Specifically, if the wire coil is packaged with a combination of an outer cover that wraps around the outer periphery and/or the vicinity of both ends, and an inner cover that wraps around both sides of the outer periphery from the inner periphery of the wire coil via both ends,
It has been discovered that it is possible to pack a wire coil without disturbing the inner circumferential space of the coil, and to dismantle the packaging easily, quickly, and reliably. Furthermore, it was discovered that the following technical issues (ranked differently) could be achieved.

a. It must be possible to prevent (including, suppress) water (including rain, water) from entering through the packaging cover, B. Water (including rainwater) must not be allowed to enter from the overlapping part of the packaging cover (waterproofness), and C. Atmospheric temperature. Prevents (including, suppresses) the occurrence of condensation due to differences in
What can be done (moisture-proofing) Prevents (including, suppresses) rust from forming on packed wire coils.
What you can do. Ability to handle and transport wire rod coils even in rainy weather. The packaging cover can be used as a simple storage area. Good workability in packing and unpacking (simplicity, speed, reliability, etc.) H. Packing and unpacking work can be carried out by at least one worker; e. The packaging can be used repeatedly (durable) c. It should be inexpensive (!! It should be reusable).
Being able to suppress or prevent the occurrence of defects in the coil; c. Being able to suppress or prevent coil deformation (package collapse); Quality information can be seen on the packaged coil [Means for solving the problem] In order to achieve the above technical problem, the present invention has the following configuration.

1. A part of the outer periphery and/or both side ends of the coiled object is surrounded by an outer cover and removably fixed with a mounting element, and an enclosing part that can be folded back is provided on the inner periphery of the space of the coiled object. While the inner cover is inserted through the inner cover, these surrounding parts are folded back in the direction of the outer periphery of the coiled object, and fixed with attachment elements in the direction of the outer periphery, so that the entire surface of the coiled object can be removed while leaving the inner periphery of the above-mentioned space. A method of packing a coiled object, characterized by packing it into a coiled object.

A cover for a coiled object according to any one of claims 3, 4, 5, 6, and 7, characterized in that a quality information mounting portion is provided on the exposed surface of the outer cover and/or the inner cover. Outer cover and/or inner cover! ! Claim 3, characterized in that it is composed of an 8T material and a waterproof material.
4, 5, 6, 7, and 8. Cover for coiled object 1G. The reason for configuring the present invention in this manner is that the outer cover and the inner cover are covered with a cushioning material and a waterproof material. The purpose of the present invention is, of course, as follows.

■A combination of an outer cover and an inner cover can be used to seal the entire circumference of the wire coil while leaving a space around the inner circumference of the wire coil, and the wire coil can be removed and packed freely. Regarding the construction of the cover: It is of course intended to suppress or prevent the occurrence of deformation of the wire rod coil, rust, and dew condensation, but also for the following reasons. In order to save labor and improve efficiency, we are considering handling wire coils with as few workers as possible. Therefore, as seen in the case of cargo handling of long steel products, cargo handling operations involving several people such as multiple sling workers, crane operators, etc. are rare. In many cases, cargo handling equipment, such as C
Loading hooks and rams (rod-shaped cargo handling equipment) (Kindai), loading and unloading onto the truck bed, managing the storage in storage, or loading the coils in an outdoor coil storage area (commonly known as
(Also called field stacking).

Therefore, when packing a wire coil, it is necessary to use a combination of an outer cover and an inner cover so that the space around the inner circumference of the wire coil can be utilized, and the entire circumference must be sealed so that it can be removed and packed at will, so the above structure is used. shall be.

■About attaching a dehumidifier and/or rust preventive agent to the contact surface of the outer cover and/or inner cover with the coiled object, or providing a storage section on the contact surface of the outer cover and/or inner cover with the coiled object. : The mechanism by which rust and condensation occur on wire coils is as described above. Therefore, in the packaging method and packaging cover of the present invention, it is necessary to install a dehumidifier and/or rust preventive agent in order to suppress or prevent the occurrence of dew condensation and/or rust even for each wire coil and maintain quality. This is a new method of packaging coils or packaging covers that cannot be found. As this dehumidifier, there are known ones, for example,
It is preferable to use Milbeat N (trade name, manufactured by Mizusawa Kagaku Kogyo ■). Also, as a rust preventive agent, it is also preferable to use a known one, for example, the product name Die-List (trade name, manufactured by Daido Kagaku ■).

On the other hand, the purpose of providing a storage section on the contact surface of the outer cover and/or inner cover with the wire coil is to attach a dehumidifier and a rust preventive agent to the outer cover and/or inner cover.
This storage section can be understood by imagining a pocket in clothing. However, it is not specified whether the storage section is provided in a fixed manner in advance on the outer cover or inner cover, or in a removable manner in which it is provided each time it is used.

■The inner cover is composed of a cylindrical part that matches the shape of the space-like inner peripheral cross section and length direction of the coiled object, and an enclosing part that can be folded back on both sides: The wire coil has a space-like shape. The inner periphery is inevitably generated during the focusing process, and this is effectively used for work and production in the process leading to the secondary processing machine. Therefore, when packing the wire coil, it is necessary to maintain this space-like inner periphery as it is, so the above-mentioned configuration is necessary.

This allows the inner cover and the outer cover to be easily distinguished and packed or dismantled. In addition, since there is a foldable enclosing part on both sides, both sides of the wire coil can be stacked with the outer cover for packaging, increasing durability and suppressing or preventing rain and water from entering from contact surfaces. Furthermore, since the entire circumference of the wire coil is surrounded, it is possible to suppress or prevent the occurrence of scratches, dew condensation, rust, etc., and it is also possible to suppress or prevent the intrusion of rain and water. This is necessary so that workers, such as truck drivers, can quickly, easily, and reliably carry out packing and dismantling operations.

■ Constructing the outer cover to be wider than the length of the coiled object in the winding axis direction and long enough to wrap around the outer periphery of the coiled object: flaws, dew condensation, etc. on the outer periphery of the wire coil and its vicinity; This is necessary to suppress or prevent the occurrence of rust, to suppress or prevent the intrusion of rainwater, to be able to handle cargo without being affected by the weather, and to achieve the other technical issues mentioned above.

■ Regarding the provision of attachment elements on the outer cover and inner cover: It is necessary that the packing and dismantling of wire coils can be carried out as easily, quickly and reliably as possible, and that the original packing state can be maintained for as long as necessary. be. Of course, it must be difficult for rain and water to enter through this mounting element, and the packing condition must be properly maintained during the cargo handling, storage, and packaging processes, and the occurrence of dew condensation, rust, etc. must be suppressed or prevented.

In order to meet these conditions, the attachment elements must be hook type, zipper type, one-way fastener type, string type, polymeric hook-and-loop fastener (trade name: Matsujiku Tape) type, belt type, gummed tape type, or a combination of these types. It is best to combine the outer cover and inner cover for packaging.This mounting element is large and made of hard material, and as it repeatedly comes into contact with other objects during cargo handling and transportation processes and storage, This is undesirable because it may cause damage to the packaging, it may become deformed and cannot be used repeatedly, or it may increase the cost of the packaging cover.

■Providing a quality information attachment part on the exposed part of the outer cover and/or inner cover: In the production of wire coils, various types of quality information sent to customers, such as JIS standard dimensions,
Weight, quality standards for consumers, and other information are displayed by attaching labels or gold tags. However, in the wood invention, the entire circumference of the wire coil is sealed by packaging while leaving a space-like inner circumference, so the quality information added during the production process becomes invisible. Therefore, it is necessary to provide a quality information attachment part on the exposed surface of the outer cover and/or the inner cover, and provide quality information thereon.

As this quality information attachment part, a transparent bag-like thing, matsujiku tape, etc. are suitable. For bag-shaped products, various quality information can be specified and displayed on the plate. In addition, when using Velcro tape, various quality information is specified and attached to a plate with an adhesive side on one side.

■For the outer cover and/or inner cover to be made of Ha-based material and waterproof material.In order to suppress or prevent the occurrence of dew condensation, rust, etc.
As shown in Figures and Figure 13, exhibiting an insulating effect to keep the temperature of the packed wire coil at a predetermined temperature, suppressing the intrusion of rain and water or preventing insects, suppressing or preventing the occurrence of scratches, packaging, Work such as dismantling can be done quickly and easily;
The cost of the packaging cover can be reduced by being repeatedly used for packaging, and in order to meet this requirement, it is necessary to use the above-mentioned impact-resistant material and waterproof material. in this case,
The buffering material not only buffers external forces on the wire coil, but also maintains the wire coil at a predetermined temperature, and together with the waterproof material, suppresses or prevents rain, water intrusion, and water permeation.

■For the outer cover and/or inner cover, the cushioning material is covered with a waterproof material (when viewed in cross section, the cushioning material is sandwiched with a waterproof material): The above configuration (■) is more preferable. For example, the waterproof material is polyethylene fiber cloth laminated with a polyethylene film of about 50 μm, and the Ha material is polyethylene foam (about 2 ms thick), which has a heat insulating effect. (trade name: Silver Mat, manufactured by Tohoku Jiko Co., Ltd.) is preferable.

The combination of cushioning material and waterproof material in ■ and ■ above is as follows:
To increase the durability of a packaging cover and enable repeated use. Regarding this durability, for example, the conventional
Compared to packing cloth No. 427 (made of synthetic fiber cloth), it exhibits durability that exceeds the expected range.

A storage section 6 is provided at an appropriate position on the surface of the outer cover 1 that contacts the outer periphery of the wire coil, so that a dehumidifier and/or a rust preventive agent can be stored therein. Since the storage section 6 shown in FIG. 2 is formed into a pocket shape, the dehumidifier and/or rust preventive agent can exert its dehumidifying and/or rust preventive effect simply by charging it, thereby achieving the intended purpose.

Note that if the storage portion 6 is provided with at least one hole 7 or made of a coarsely woven material, dehumidification and/or rust prevention can be better achieved.

The dimensions of the outer cover 1 are such that the longitudinal direction is longer than the outer circumference of the wire coil, and the width direction is wider than the width of the wire coil (in the winding axis direction of the wire rod), so that it can wrap at least the vicinity of both ends of the wire coil. It is preferable to have as much width as possible.

Alternatively, the cushioning material 33 is covered with a waterproof material 34, that is, the cushioning material 3 is sandwiched between the waterproof material 34 and the cushioning material 3 to form a triple-layered structure when viewed in cross section. The product name Silver Mat (Tohoku Jiko ■) is preferred.

FIG. 3 shows another embodiment of the outer cover 1. This is a mounting element that can be attached by hooking a C-hook-shaped hanger 9 onto a ring-shaped receiver 8, and the thing that attaches these receivers 8 and hanger 9 is an elastic body. If there is, tension is generated, so that the outer cover 1 can be normally attached to the outer periphery of the wire coil. Furthermore, if the elastic body is replaced by a hoop-shaped or string-shaped body having approximately the same length as the outer periphery of the coil, the receiver 8 and the hook 9 can be hooked and attached normally.
