DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process of transporting a steel strip coil by a transport facility, wherein an axial direction of the steel strip coil is kept horizontal, and dirt such as oil adhering to a coil receiving surface of the transport facility on the outer peripheral surface of the steel strip coil. The present invention relates to an apparatus for pasting a sheet of paper to a steel strip coil, which prevents adhesion of a sheet.

[0002]

2. Description of the Related Art In a steel strip surface treatment line such as galvanizing, a rust preventive treatment is applied to the steel strip surface by applying a rust preventive oil or a chemical conversion treatment for the purpose of preventing rust of the steel strip after the surface treatment. Is performed. Usually, these rust prevention treatments are continuously performed on a production line, and the treated coils are wound into a coil shape by a winder, bound in a band, and then conveyed to the next step by a coil conveyance facility.

[0003] Here, the steel strip coil coated with the rust-preventive oil naturally has the rust-preventive oil adhered also to the outer peripheral portion of the coil. Therefore, the side of the transport equipment for transporting the coil (particularly, the coil receiving seat portion). The rust preventive oil is also transferred. In the transfer equipment, there is no particular problem as long as all the coils to be transferred are coils coated with rust-preventive oil. Coil (hereinafter referred to as an oilless coil. In this case,
Since oil is not transported, the oil deposited on the transport equipment side is transferred to the coil, which is a problem.

Conventionally, when a non-oil-coated coil treated on a surface treatment line is transported, as shown in FIGS. 6 and 7, a coil placed near the entrance of the transport facility before the coil is placed on the transport facility. Place on seat 7. Then, the coil 6 is lifted using the coil tongue 5 in which the coil 6 on the receiving seat 7 is hung on the hook 12 of the overhead crane. It was carried on a possible coil receiver.

[0005] In this case, the work requires not only a long stop of the transport equipment but also work under the lifted coil, which is extremely dangerous. By the way, conventionally, the width of the sheet 4 is shown in FIG.
As shown in FIG. 5 (b), after cutting the covering paper 4 drawn from the covering coil 1 having a width W substantially equivalent to the width of the steel strip coil 6 to be affixed to an appropriate length L, FIG. As shown in the figure, the steel strip coil 6 is fed from the circumferential direction according to the width,
It was applied to the bottom surface of the steel strip coil 6 and attached using an adhesive tape 13.

[0006] As disclosed in Japanese Patent Publication No. 2-10009, a wrapping paper supply device is provided on a steel strip coil on a cradle roller on which a coil is placed and rolls, and the wrapping paper is used to wrap the coil. Means for wrapping the entirety and wrapping the edges of the wrapping paper with an adhesive tape are also known.

[0007]

As described above with reference to FIG. 5, a method of applying the width of the wrapping paper 4 drawn from the wrapping paper coil 1 to the width of the steel strip 6 using the adhesive tape 13 is used. It is necessary to replace the laying sheet coil 1 every time the width of the steel strip coil 6 changes, and to adjust the width. For this reason, it is necessary to prepare a sheet coil 1 having various widths.
Not only does the cost increase, but also the sheet coil 1 needs to be replaced each time, which complicates the operation. After the sheet 4 is applied to the lower surface of the steel strip coil 6, the adhesive tape is further applied.
A complicated mechanism for mounting using 13 was required, and work efficiency was not good.

[0008] The means for packaging the entire steel strip coil on the cradle roller is not suitable for attaching a sheet of paper in the course of processing the steel strip. When the unoiled coil is transported by the transport equipment, if the oil adhering to the coil seat of the transport equipment is cleaned using a cleaning agent, it is possible to eliminate the necessity of attaching a sheet of paper to the steel strip coil. . However, if there is a large number of coil seats from the coil processing line, such as the plating line and recoil line, to the coil packing line via coil transfer equipment and coil storage, etc., all of these seats should be completely cleaned. This requires a large-scale facility and is expensive because a large amount of expensive cleaning agent is used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and when an uncoated oil coil manufactured in a coil processing line is transported to the next process by a transport facility, it adheres to a coil seat of the coil transport facility. It is an object of the present invention to provide a method of attaching a sheet of paper to a steel strip coil which can prevent the oil being applied from adhering to an uncoated oil coil.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is to lift a steel strip coil in a state where the axial direction is horizontal, and to attach a sheet of paper to the outer periphery of the lower surface thereof while rewinding the sheet of paper coil. After applying glue to both edges or pulling out a sheet of paper having a glue application part with glue applied in advance,
This sheet of paper is cut at right angles to the drawing direction in accordance with the width of the steel strip coil, and the cut sheet of paper is disposed inside each of the glue application sections at both end edges so as to correspond to each pair. While being fed and pinched between the pinch rolls, it is fed from the end face side of the steel strip coil lifted in the down-end state and positioned below the steel strip coil. Affixing the wrapping paper to the steel strip coil, wherein the cloth part is applied to the steel strip coil while turning both pinch rolls upward along the outer circumference of the coil so that the cloth portion is oriented in the width direction of the outer circumference of the lower surface of the steel strip coil. It is a method of attaching.

[0011]

According to the present invention, after a sheet of paper having glue-applied portions at both edges is drawn out, the sheet is cut to a length corresponding to the width of the target steel strip coil. Then, the pinch rolls are sandwiched between the rolls, and the paste is applied so that the glue coating at both edges is directed in the width direction of the outer periphery of the lower surface of the steel strip coil. Paste. For this reason, if there is only one kind of width for the sheet coil, the sheet can be cut into a required length corresponding to the width of the various types of steel strip coil, and then the sheet paper can be pasted.
