Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire coil automatic packing device.

[0002]

2. Description of the Related Art Conventionally, a wire wound in a coil is
After hot rolling, it is stored as it is in a warehouse or stockroom and shipped from there to customers.However, wire rod coils that have been bound, weighed, etc. have scratches or the like due to contact between the coils. Since it is in an easy state, wire flaws at the time of loading and unloading, product contact at the time of stacking, at the time of transportation and stacking in the factory, at the time of shipping from the factory by sea, by sea, by freight car or by car Defects, scratches, etc. occur. Particularly in recent years, surface defects during transportation have come to be regarded as a problem along with the sophistication of products, and for that reason, packaging has been required.

However, as a conventional method of packing a wire rod coil, as disclosed in Japanese Patent Publication No. 62-18427, a rectangular synthetic fiber cloth is used with a fastener and a string or a rope. The outer circumference and end surface of the wire rod coil by fastening both ends of the packing cloth with fasteners and squeezing and binding the drawstrings or loops on both open end sides of the wire rod coil. It is a method of coating. Further, the method disclosed in Japanese Patent Laid-Open No. 52-90382 relates to an improvement of a packing device for performing a gate winding in which a strip-shaped packing material such as rust-proof paper is sequentially shifted and wound around a material to be packed such as a wire coil. Therefore, when there is no band-shaped packing material in use, or when different kinds of band-shaped packing materials have to be used, the packing apparatus is designed to be able to immediately perform the packing work following the conventional packing work.

[0004]

As described above, as a conventional wire rod coil protecting means, there is disclosed in Japanese Unexamined Patent Application Publication No. Sho 62-62.
As in the method disclosed in Japanese Patent No. 18427, a synthetic fiber must be prepared according to the size of each wire rod coil before packing, and this cloth can be attached to a fastener and a string or a rope. Since the outer peripheral surface of the coil is a method of covering the end surface, the work must be done manually, and
It is hard to say that the coating itself is strong, the coating of the inner peripheral surface of the wire rod coil cannot be done, and the packing work speed of the wire rod is slower than the binding work speed of the bundled wire rod. There is a problem that it is impossible to carry out work continuously. Further, although it has been automated by the packing by the gate winding method in which the band-shaped packing material disclosed in Japanese Patent Laid-Open No. 52-90382 is sequentially shifted and wound, the band-shaped shape serves as a buffer for the inner and outer surfaces and end surfaces of the wire coil. However, from the viewpoint of preventing moisture such as intrusion of rainwater during transportation and preventing rust, there is a problem that the seal at the joint of the band-shaped packaging material cannot be perfect.

[0005]

The present invention is to solve the above-mentioned problems of the prior art. As a result of the inventors' earnest efforts, the packing sheet has a rectangular minimum necessary area.
In addition, it does not require pre-processing and enables automatic packing as it is. The gist of the invention is to have a pair of cradle rolls and a driving device for the cradle rolls, and a wire rod coil and cylindrical sheet forming members on both sides of the coil are placed on the cradle rolls. The packing sheet front end portion is fixed to the sheet forming member by a holding member, and the wire coil and the sheet forming member are simultaneously rotated by the rotation of the cradle roll. It is located in the wire coil coil sheet automatic winding device.
