Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal coil packing member having a condensation discharging function, and a packing member having a preferable condensation preventing function at the time of storing or shipping the metal coil, or a packing formed by using the packing member. It relates to parts or packaging methods.

[0002]

2. Description of the Related Art Metal materials are commercialized in the form of coils and are used for cargo handling.
Generally, it is stored, and the usual method conventionally used for packing this metal coil, particularly an iron-based metal coil, is as follows. As shown in FIGS. 12 and 13 are attached, that is, the inclusion sheet 13 is attached to the bottom surface and the peripheral surface, and the lid sheet 12 is applied to the top surface. On metal ring 1
It is usual to attach 8 and 19 and fix these members 12 to 14 and 18 and 19 with a hoop 15 to protect the product or prevent rusting as shown in FIG. is there.

In Japanese Utility Model Laid-Open No. 62-122083, it is announced that the metal sheets on the inner, outer and side surfaces are sealed with an adhesive tape to prevent the infiltration of dew and improve the prevention of rusting.

[0004]

However, the conventional technique described above is still insufficient, and the technique shown in FIG. 4 requires the coil 1 as shown in FIG.
Moisture easily accumulates on the inner surface plate 16 which is a metal plate attached to the inner surface of No. 1 to cause dew condensation, and this dew condensation water (W) is guided as shown by an arrow (WR) and is a rust preventive sheet.
3 is likely to reach inside and outside, and in any case coil 1
No. 1 shows rusting.

In the above-mentioned Japanese Utility Model Laid-Open No. 62-122083, it is not easy to properly attach the adhesive tape along the inner circular arc of the coil when the adhesive tape is attached to the inner peripheral side of the coil. , This workload will be very high. Moreover, since the double-sided pressure-sensitive adhesive tape stuck on the metal plate and the metal plate must be separated for the work of unpacking such packaging, the work load of the unpacking work by the user is larger than usual and it is not dangerous. I have no choice.

DISCLOSURE OF THE INVENTION The present invention has been studied to solve the problems in the prior art as described above, and accumulated on the inner peripheral side of the coil by using a special donut plate and a partial metal ring. The dew condensation water is properly prevented from entering, avoiding rusting and increasing the work load on packing and unpacking, and is as follows.

[0007] In the metal coil packing part, wherein the coil part is covered with rustproof paper, and the end face donut plate, inner and outer peripheral metal sheets and inner and outer peripheral cornering are attached to bind the coil part, The ring part body that partially covers the inner circumference side and the end face of the coil part body between the plate and the inner peripheral surface metal sheet is additionally provided at least below the inner circumference of the coil part body. A metal coil packing unit with a dew condensation discharging function.

[0008]

In the metal coil packing body, the coil body is covered with rustproof paper, and the end face donut plate, the inner and outer peripheral metal sheets, and the inner and outer peripheral cornering are attached to bind the coil body. The ring part body that partially covers the inner circumference side and the end face of the coil part body between the plate and the inner peripheral surface metal sheet is additionally provided at least below the inner circumference of the coil part body. As a result, the dew condensation due to the moisture that has penetrated into the inner circumference of the coil body is dripped from the inner circumferential metal sheet to the outside of the end face donut plate that holds the outer surface of the semicircular ring body.

The ring portion can be prevented from invading into the coil portion body of the dew condensation water which flows down or drops by being additionally provided at the lower part of the inner circumference of the coil portion body, but generally has a cylindrical shape. It is difficult to confirm the lower position due to the rolling of the coil body.Also, even if it is possible to confirm the lower position by adding a mark etc., the lower position is always positioned downward and is left stationary. In such a case where it is complicated, the object of the present invention can be achieved by using a circular ring portion that is continuous in the entire circumferential direction regardless of the direction. Further, the ring part is prevented from being damaged by lifting by a crane or wire hanging, fixing on the ship by wires or hoops, or binding the coil package.

As described above, the circular ring member which is continuous in the entire circumferential direction may be an integrally formed member, but it is formed by combining two or more semi-circular members. be able to.

EXAMPLE A concrete embodiment of the above-mentioned present invention will be described. A wound coil body 1
The resin-coated rustproof papers 2 and 3 are attached to the inner and outer peripheral surfaces of the package and wrapped, and the metal donut plate 4 is attached to the end surface of such a packaging coil, and the end surface and the inner peripheral surface are partially cleaved. A semi-circular metal ring 5 as shown in FIG. 2, which is bent and formed to have an L-shaped cross section, is attached to both ends of the lower inner circumference of the coil.

Further, an inner surface plate 6 and an outer surface plate 7 are attached respectively to the inner and outer peripheral surfaces of the coil 1 as described above, and an inner peripheral side corner ring 8 and an outer peripheral side corner ring 9 are attached, which are shown in FIG. Similarly to the above, fastening and fixing with the hoop 10 is the same as the conventional one.

The metal donut plate 4 described above is the coil body 1.
Of the semicircular metal ring 5 is attached to the lower part of the inner circumference of the coil as shown in the drawing, but the upper part of the inner circumference of the coil is a full-circle type. As described above, the ring 5 may be partially encased, but the ring 5 is mainly intended to discharge dew condensation, and is thin and lightweight in terms of workability, cost, and work. Is preferable, plate thickness is around 0.4 mm, TS = 40 kg /
It is preferable that the diameter is around mm ² from the viewpoint of handling and attachment.

A concrete example of the present invention and a comparative example thereof will be described. The coil packing part according to the present invention as shown in FIG. 1 and FIG. 2 and the outer part not using the semi-circular metal ring 5 are described. As a comparative example, a coil part having a width of 1219 mm and a diameter of 1450 mm and a weight of about 10 tons, which were all packed with the same material according to the conventional method, was prepared as a comparative example.

That is, 5 packaging packages of the present invention and 5 packaging packages for comparison were prepared respectively, and 2 liters of colored water were sprayed on the front surfaces of these coil packaging bodies, respectively, and left for 10 days before unpacking. When the rusting state in the coil was examined, no rusting in the coil could be recognized in any of the examples of the present invention, whereas in the comparative example, all the coils were attached to the inner peripheral surface packaging metal sheet part. Colored water infiltrated and accumulated, and in the two coils among them, water was infiltrated up to the rust-preventive paper on the inner peripheral surface, and dot-like rusting was also confirmed on the inner surface of the coil itself.

The packaging according to the present invention is
The operation of loading and unloading the inner peripheral cornering 5 for discharging the dew condensation is very easy, and in particular, a semi-circular shaped and prepared one may be simply attached, and the I / E value of the loading / unloading work is about 18DM. Yes, the ease of packing work was confirmed.

[0017]

As described above, according to the present invention, it is possible to effectively prevent dew condensation in the metal coil package, properly prevent rusting, and increase the work load in packing and unpacking work. In any case, since it is possible to provide an advantageous packaging part, it is an invention that is industrially highly effective.
