Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a sheet-like packing material for wrapping an object to be packed, such as a cylindrically rolled plate, and in particular, to a sheet-like packing material that can be securely fitted to the corner of an object to be packed. Concerning structured packaging materials.

[Prior art]

FIG. 6 is a perspective view showing a state in which plate materials such as iron plates wound into a cylindrical shape are packed. This type of packaging usually involves the following steps: First, as shown in FIG. 7, the sheet 2 is wound around the outer periphery of the cylindrically wound object 1 to be packaged. This sheet 2 is made of paper or a material made of paper and a resin film in close contact with each other. The sheet 2 is wound around the object to be packed 1 and fixed with tape or the like. Then, as shown in FIG. 6, a metal outer peripheral covering plate 3 is wrapped around the outer periphery of the sheet 2, and an end face covering plate 4 is attached to the end face of the object to be packed 1. And the corner A of the outer periphery
and cap materials 5 and 6 are attached to the inner corner B,
It is fixed by a band 7.

[Problems with conventional technology]

As shown in FIG. 7, when the sheet 2 is wound around the object 1 to be packed, a fold α is provided at the end of the sheet 2 to form an end surface covering portion 2a that covers the end surface of the object 1 to be packed. Become. However, the sheet 2 made of paper or the like can be deformed freely due to the nature of the material. Therefore, unless the folds α are sequentially formed while holding the end face covering portion 2a, the end face covering portion 2a will open as shown by the chain line in FIG. Furthermore, when folding the tip 2b of the end face covering portion 2a into the inner circumferential portion of the object to be packed 1, the work must be carried out while being held down in the same manner. Since the packing operation using the sheet 2 has such inconveniences, conventionally, the operation of winding the sheet 2 had to be performed manually.

However, recently, in order to improve the efficiency of packing operations, consideration has been given to adopting automatic packing operations using automatic machines. It is fully possible to perform the process of forming the fold α at the end of the sheet 2 and folding the end face covering portion 2a using an automatic machine. However, as described above, the end of the sheet 2 opens as shown by the chain line in FIG. 8, which poses a problem in automatic operation.

[Purpose of invention]

The present invention has been developed by focusing on the above-mentioned conventional problems, and it is possible to fold the sheet by ensuring that the sheet wrapping the object to be packed fits the corner of the object and preventing the edge of the sheet from opening. make your work easier,
The aim is to provide packaging materials that also enable automation of sheet wrapping work.

[Summary of the idea]

The packaging material according to the present invention is made up of a sheet that wraps the entire object to be packed, and reinforcing members made of thin metal plates such as iron or aluminum attached to the corners of the object to be packed. be.

In this invention, a reinforcing member made of a thin metal plate is attached to the sheet, and this reinforcing member is attached to the corner of the item to be packed, so the reinforcing member can be bent to fit the corner. This allows the sheet to fit completely around corners.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings of FIGS. 1 to 6.

Fig. 1 is a perspective view showing the state in which the packing material of the present invention is wrapped around an object to be packed, Fig. 2 is a sectional view showing the state in which the packing material is wrapped, and Figs. 3 and 4 show the structure of the packing material. It shows.

Reference numeral 1 indicates an item to be packed. This packaged item 1 is
A plate material such as a metal plate is rolled into a cylindrical shape. In the first step of the packing operation, the outer surface of the object to be packed 1 is wrapped with the packing material 10 according to the present invention.

As shown in FIG. 3, the packaging material 10 is composed of a main sheet 11 such as paper and an auxiliary sheet 12 such as resin film or resin cloth, which are in close contact with each other, and between both sheets 11 and 12, A reinforcing member 13 made of a thin plate of metal such as aluminum or iron is interposed.

As shown in FIG. 1, this reinforcing member 13 is provided at a position where it is attached to a corner A of the outer periphery of the object to be packed 1. As shown in FIG. This reinforcing member 13 is formed into a thin film shape of about 50 μm, and can be relatively freely deformed following the sheets 11 and 12, and is in a plastic state when bent and deformed. It has a rigidity that can be maintained at
The packaging material 10 is manufactured by, for example, adhering the reinforcing member 13 to the main sheet 11, and then adhering or thermocompressing the auxiliary sheet 12 to the inner surface of the main sheet 11.

When wrapping the object 1 with the packing material 10, as shown in FIG. Fold it to match A. Then, the folds α are sequentially formed to form the end face covering portion 10a. When the reinforcing member 13 attached to the corner A is bent at almost a right angle, the packaging material 10 will completely fit the corner A, and the end cover will open as shown by the chain line in FIG. Not at all. Therefore, when forming the end face covering portion 10a, there is no need to press the sheet portion, so that automatic folding work can be performed using an automatic machine. Further, the operation of folding the tip end 10b of the end face covering portion 10a into the inner diameter portion of the object to be packed 1 can be easily performed.

Further, the reinforcing member 13 is an auxiliary sheet 1 made of resin.
2, the reinforcing member 13 does not come into direct contact with the object 1 to be packed, but the auxiliary sheet 12 comes into contact with the object 1 to be packed. Therefore, the object to be packed 1 will not be damaged by the reinforcing member 13, and even if the reinforcing member 13 is made of iron, rust or the like will not adhere to the object to be packed 1.

In the next step of the packing operation, the packing material 10 wrapped around the object to be packed 1 is fixed with tape or the like. Then, as shown in FIG. 6, the outer periphery and end face covering plate 3 and end face covering plate 4 are attached to the outer periphery and end face of the packaging material 10, and the cap materials 5 and 6 are fitted, and the packaging material 10 is fixed with a belt 7 and packed. Complete the work.

Note that, as shown in FIG. 4, if the width l of the reinforcing member 13 is set to a large dimension in advance, even if the length L changes depending on the type of the object to be packed 1,
It becomes possible to always attach the reinforcing member 13 to the corner part A, and it becomes possible to provide versatility.

Moreover, the auxiliary sheet 12 is not provided in the packaging material 10,
The reinforcing member 13 may be exposed on the inner surface of the main sheet 11. In this case, if the reinforcing member 13 is made of a rust-resistant material such as aluminum, it is possible to prevent rust from adhering to the object to be packed 1 . Alternatively, the reinforcing member 13 may be attached to the outer surface of the main sheet 11 so that the reinforcing member 13 touches the corner A from the outside of the main sheet 11. In this case, even if the reinforcing member 13 is made of a material that easily rusts, such as iron, it will not affect the object 1 to be packed.

Furthermore, the reinforcing member 13 may be provided at a position where it can be attached not only to the corner A on the outer periphery of the object to be packaged 1 but also to the corner B on the inner periphery. In this case, the reinforcing members 13 attached to the corner A and the corner B may be provided separately, or a reinforcing member 13 with a large width may be provided, and one reinforcing member 13 may be attached to the corner A and the corner B. It may be configured to cover both corners B.

Furthermore, as shown in FIG. 5, a rectangular object to be packed can be wrapped with the packing material 10 according to the present invention. In this case as well, reinforcing members 13 are attached to the corners of the object to be packaged.

[Effect of idea]

As described above, according to the present invention, the reinforcing member attached to the corner of the object to be packed is provided, so that the packing material can be completely fitted to the shape of the corner of the object to be packed. . This prevents the packaging material from opening during the packing process, and the process can proceed reliably. Therefore, it becomes possible to automate the packing work using packing materials using an automatic machine.
