Description

  The present invention relates to a metal band coil packing method and a metal band coil package used when a metal band coil such as a steel band wound in a coil shape by a winder is shipped as a product.

Generally, a steel strip wound in a coil shape by a winder is called a steel strip coil or a steel strip coil. And when this steel strip coil is transported on a carriage or conveyor by a crane or the like, it is disclosed in Patent Documents 1 to 4 in order to prevent the winding of the steel strip coil from being loosened during transport. The steel strip coil is transported after the outer peripheral surface of the steel strip coil is tightened by the metal binding band.
In addition, when shipping steel strip coils whose outer peripheral surface is tightened with a binding band as a product, the steel strip coils are encapsulated with rust-proof paper to prevent rust on the surface of the steel strip coils. (For example, refer to Patent Document 5).

The fastening band 16 has a thickness of about 0.7 mm and a width of about 32 mm, for example, and the coil protection plate 15 is fastened and fixed to the outer peripheral surface of the metal band coil 11 at a position where it does not overlap with the binding band 12. ing.

The fastening bands 21a to 21f are used to fasten and fix the coil protection rings 17a and 17b, the coil protection rings 19a and 19b, and the coil protection plates 20a and 20b to the side surface of the metal band coil 11, and are made of metal such as steel. Has been.
FIG. 12 shows a state in which the coil protection plate 15 is fastened to the outer peripheral surface of the metal band coil 11 at a position where the fastening band 16 overlaps with the binding band 12, and the coil at a position where the fastening band 16 does not overlap with the binding band 12. FIG. 13 shows a state in which the protective plate 15 is fastened to the outer peripheral surface of the metal band coil 11.

  In the state shown in FIG. 12, since the fastening band 16 overlaps with the binding band 12, when the heavy object 22 falls on the fastening band 16, the weight of the heavy object 22 is added to the surface of the binding band 12, and the binding band 12 is bound. Pushing tends to occur on the outer peripheral surface of the metal band coil 11 due to the weight of the heavy object 22 applied to the surface of the band 12. For example, assuming that the band width of the binding band 12 is W, the band width of the fastening band 16 is W, and the weight of the heavy object 22 is P, the stress expressed by σ1 = P / W on the surface of the fastening band 16 (Here, the weight per unit bandwidth is shown). Then, a stress represented by σ1 = P / W is applied to the surface of the binding band 12, and a push is generated on the outer peripheral surface of the metal band coil 11 by the stress σ1.

  On the other hand, in the state shown in FIG. 13, since the fastening band 16 does not overlap the binding band 12, the weight P of the heavy object 22 remains on the surface of the binding band 12 even if the heavy object 22 falls on the fastening band 16. Therefore, it is possible to prevent the pressing band due to the binding band 12 from being generated on the outer peripheral surface of the metal band coil 11. For example, if the band width of the binding band 12 is W, the weight of the heavy load 22 is P, and the contact width between the coil protection plate 15 and the heavy load 22 is S (> W), the surface of the coil protection plate 15 has σ2 = Stress expressed by P / S (here, the weight per unit contact width is shown) is applied. Then, a stress represented by σ2 = P / S is applied to the surface of the binding band 12, and the stress σ2 at this time is a value smaller than the stress σ1. Occurrence of the coil 11 on the outer peripheral surface can be prevented.

  As described above, a metal coil protection plate 15 is wound around the outer periphery of the metal strip coil 11 from above the packing paper 13, and the coil protection plate 15 is fastened to the outer periphery of the metal strip coil 11 with the fastening band 16. When fixed, the outer peripheral surface of the metal strip coil 11 can be protected from impact force by the coil protection plate 15. Therefore, it is possible to prevent damage that lowers product quality from occurring on the outer peripheral surface of the metal strip coil 11.

  Further, if the coil protection plate 15 is fastened and fixed to the outer peripheral surface of the metal band coil 11 at a position where the binding band 12 and the fastening band 16 do not overlap, the weight 22 will drop even if the heavy object 22 falls on the fastening band 16. Since the weight of the object 22 does not directly act on the surface of the binding band 12, it is possible to prevent the pressing by the binding band 12 from occurring on the outer peripheral surface of the metal band coil 11.

FIG. 14 shows the result of investigating the relationship between the value obtained by dividing the band interval between the binding band 12 and the fastening band 16 by the band width of the binding band 12 and the generation ratio of the pressing band 12.
The coil protection plate at a position where a value (δ / W) obtained by dividing the band interval δ (band interval between the binding band 12 and the fastening band 16) shown in FIG. 13 by the band width W of the binding band 12 is smaller than zero. It can be seen from the results of the investigation shown in FIG. 14 that when the fastening band 16 is fastened to the outer peripheral surface of the metal band coil 11 by the fastening band 16, the ratio of occurrence of pressing by the binding band 12 increases.
Further, the coil protection plate 15 is made of metal by the fastening band 16 at a position where a value (δ / W) obtained by dividing the band interval δ between the binding band 12 and the fastening band 16 by the band width W of the binding band 12 becomes zero or more. It can be seen from the investigation results shown in FIG. 14 that when the band coil 11 is tightened to the outer peripheral surface, the generation ratio of the pressing band due to the binding band 12 rapidly decreases.

  Therefore, the outer periphery of the metal band coil 11 is attached to the coil protection plate 15 by the fastening band 16 at a position where the value obtained by dividing the band interval δ between the binding band 12 and the fastening band 16 by the band width W of the binding band 12 becomes zero or more. By tightening to the surface, it is possible to prevent the pressing band due to the binding band 12 from being generated on the outer peripheral surface of the metal band coil 11. The coil protection plate 15 is attached to the outer peripheral surface of the metal band coil 11 by the tightening band 16 at a position where the value obtained by dividing the band interval between the binding band 12 and the tightening band 16 by the band width of the binding band 12 becomes zero or more. When tightening, the coil protection plate 15 is fastened to the outer peripheral surface of the metal band coil 11 by the tightening band 16 in a range where the position of the tightening band 16 does not deviate from both ends of the metal band coil 11.

In the above-described embodiment of the present invention, the outer peripheral surface and the side surface of the metal band coil 11 are covered from the top of the packing paper 13 with the buffer body 14, and then the metal coil protection plate 15 is provided on the outer peripheral surface of the metal band coil 11. The coil protection plate 15 may be directly wound around the outer periphery of the metal strip coil 11 from above the packing paper 13.
Moreover, in one Embodiment of this invention mentioned above, after coat | covering the outer peripheral surface of the metal strip coil 11 with the coil protection board 15, both sides | surfaces of the metal strip coil 11 are coil protection rings 17a and 17b and coil protection rings 19a and 19b. The coil protection plates 20a and 20b are covered with both sides of the metal band coil 11, but the metal bands are covered with the coil protection rings 17a and 17b, the coil protection rings 19a and 19b, and the coil protection plates 20a and 20b. A coil protection plate 15 may be wound around the outer peripheral surface of the coil 11.
