Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an inner edge packing material feeding device for a steel plate coil,

The present invention relates to a steel sheet coil inner edge packaging material feeding device, and more particularly, to a steel sheet coil inner corner wrapping material feeding device for feeding a wrapping material to a steel plate coil and allowing the wrapping material to adhere to an inner edge of the steel plate coil.

The steelmaking process consists of a steelmaking process to produce various materials such as iron ore using raw materials, a steelmaking process to remove molten steel from impurities, a casting process to convert the molten steel into a solid state, And the like.

In the casting process, molten steel in a liquid state is injected into a mold, which is then passed through a continuous casting machine and cooled and solidified to form an intermediate material such as a continuous slab, bloom, or billet. The slab is produced as a product in the form of a thin steel plate while passing between a plurality of rolls rotating in the rolling process. The steel sheet produced in this way is wound in the form of a steel sheet coil for convenience of distribution.

The steel plate coil wound in the shape of a steel plate coil is provided with an anti-rust paper wound around the inner and outer circumferences of the steel coil for moisture proofing, an outer circumferential protection plate for protecting the outer circumferential surface of the steel coil, an inner circumferential protection plate for protecting the inner circumferential surface of the steel coil, A side surface side plate, an inner ring for fixing the inner circumferential protection plate to the inner circumferential surface of the steel plate coil and protecting the inner edge of the steel plate coil, and an outer circumferential ring for securing the outer circumferential protection plate to the outer circumferential surface of the steel plate coil while protecting the outer edge of the steel plate coil. The inner and outer circumferential surfaces of the steel coil are packed.

After packaging the inner and outer surfaces of the steel coil with these packing materials, a binding process is performed to wrap the inner and outer circumferential surfaces of the steel coil with bands to prevent unwinding of the steel coil and binding of the packing materials.

An apparatus for carrying out such a series of steel sheet coil packaging processes has already been disclosed in Korean Patent Registration No. 0946339, etc. However, the process of supplying the inner ring is still a manual process. Therefore, an automatic apparatus for supplying the inner ring to the steel plate coil is required.
