Abstract

PURPOSE:To automatize packing by a method wherein a bundled and bound wire coil is wrapped up circumferentially with a packing material by operation of winding apparatuses arranged before and behind the bundled and bound wire coil with the end parts of the packing material tucked into the inside of the coil by a tucking apparatus and external binding is applied afterward to the packaged wire coil. CONSTITUTION:A coil carrying truck 2 is received to a placing stand 1 and a coil moving machine A is arranged in an area to which the coil carrying truck 2 can approach. A rebinding machine 3 that rebinds a bundled wire coil so that it may not collapse is provided in an area secured for the coil moving machine A. After rebinding the wire coil is guided to a drum binding machine 5 by operation of a coil transfer machine B through a handwork executing part 4. After binding material is wound round the drum of the coil, packing material 6 is supplied to a place near the wire coil. Then the wire coil is circumferentially wrapped with the packing material by operation of a winding apparatus 8 equipped with a pair of cradle rolls, and end parts of the packing material are tucked with a tucking apparatus 9 to wrap the end parts of the coil. After that, external binding is applied to the wrapped wire coil with an automatic external binding machine 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic wire coil packaging method and apparatus.

[0002]

2. Description of the Related Art Conventionally, a wire wound into a coil and bundled and bundled is temporarily stored in a warehouse or an inventory area after hot rolling, and then shipped to customers.
Wire rods that have been bound and weighed are susceptible to scratches and the like due to contact between the coils, so when transporting and stacking within the factory, or when shipping from the factory by sea, During land transportation by freight cars and automobiles, wire flaws during cargo handling, product flaws during product stacking, scratches, and the like may 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, as an apparatus, Japanese Patent Laid-Open No. 52-90
A device for wrapping a band-shaped packing material disclosed in Japanese Patent No. 382 in a gate winding shape, and a wrapping material 2-108.
As disclosed in Japanese Patent No. 807, there is known a device in which a packaging material folded into a predetermined shape is passed through an inner surface of a coil, and a bag opening machine opens and packages the bag.

[0004]

As described above, in the conventional packing work of the wire rod coil, preparation of materials, winding, folding, and external binding are complicated work and require heavy skill. Nevertheless, I was forced to rely on manual work. In addition, the packing work speed of the wire rod is slower than the working speed of binding the bundled wire rod, so that it is impossible to perform the binding work and the packing work continuously,
Therefore, each process had to be performed separately. As a result, there are problems such as an increase in packing work cost, surface defects due to an increase in the number of times of handling, deterioration of quality such as rust during the storage period before packing work, and inability to speed up packing. .. Further, in the method disclosed in Japanese Patent Publication No. 62-18427, since the wire rod coil is covered with the fastener and the cord or the rope, the work must be done manually, and the coating itself is strong. It is hard to say that it is not so good, and there was a problem that it was not possible to prevent the generation of rust because the inner peripheral surface of the wire rod coil could not be covered.

Further, in the method disclosed in Japanese Patent Laid-Open No. 52-90382, the band-shaped packing material serves as a buffer for the inner and outer surfaces of the wire coil and the end surface, but from the viewpoint of preventing moisture from entering rainwater during transportation and preventing rust. Therefore, there is a problem that the seal of the joint of the band-shaped packaging material cannot be perfect. Also,
In the device disclosed in Japanese Utility Model Laid-Open No. 2-108807, it is necessary to fold the packaging material one by one according to the wire coil dimensions into a predetermined shape before packaging, which is problematic in terms of workability and cost. Also, pass the packing material through the inner surface of the coil,
Since the material is opened by the bag opening machine and then the complicated work of folding it back to the outer surface of the coil is sequentially performed by the same device, there is a problem that the device becomes complicated and packing time is required. In addition, there is a problem that manual work remains because the method of stopping the material after packing binds the edge portion with a wire or a string.
