BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a top guide which is provided on a pinch roll entrance side and which enables a metal strip passing through a line to be stably fed into a coiler via a pinch roll. A metal such as a steel strip obtained by joining a back and forth sheet bar on the entry side of a rolling mill and continuously hot rolling a plurality of sheet bars or hot rolling a long sheet bar. The present invention relates to an auxiliary guide for a top guide suitable for passing a strip in a continuous hot rolling line (hereinafter, also referred to as an endless rolling line) in which a band is cut by a shear arranged on the entrance side of a winder and wound by a plurality of coilers. .

[0004] The metal strip S passed through in the direction of the arrow in the figure is continuously rolled by the finishing mill 1 and cut by the shear 10 via the transfer table 13. Pinch rolls 9 and 11 are arranged before and after the shear 10. The cut metal strip S is supplied to an upstream winding facility 40 comprising a No. 1 coiler 14a and a pinch roll 2 and a downstream winding facility 41 comprising a No. 2 coiler 14b and a pinch roll 3 in a subsequent process. It is wound up alternately. In order to feed the metal band S to the pinch rolls 2 and 3 in front of the coiler, an introduction guide 6 and a top guide 5 are provided on the entry sides of the pinch rolls 2 and 3, respectively. In the drawing, reference numeral 4 denotes a scraper disposed on the exit side of the pinch roll. Here, in the case of FIG. 2, the second and subsequent endless rolling, that is, the state of passing the succeeding material after cutting the metal band S with the shear 10 is shown, and the top guide 5 is placed on the upper side. It is flipped up and is in an unused state. The top guide 5 will be further described later.

In order to stably feed the metal strip S to the introduction guide 6, a sheet passing device 7 is provided on the transport table 13 in front of the pinch rolls 2 and 3. In the endless rolling line, it is necessary to pass the metal strip at a high speed for reasons such as securing a winding temperature when the metal strip S is wound around the coiler, and the sheet passing speed reaches 1000 mpm or more. In order to realize such high-speed threading, the threading device 7 is indispensable equipment.

[0006] As shown in FIG.
20 makes it possible to move up and down, and narrows the gap between the pass line 12 (transport table line, the same applies hereinafter) shown by a two-dot chain line in FIG. Is to be sent stably. As in the case of the second and subsequent metal strips S cut by the shear, the gap between the lower surface of the sheet passing device 7 and the transfer table line at the time of steady metal strip passing is about 30 to 35 mm. The case where the first end portion of the endless rolling of the metal strip or the batch rolled material is passed will be described later.

Next, a description will be given of the metal strip floating plate. As shown in FIG. 4, a gas jet port for jetting a gas flow 23 obliquely from a substantially central portion of the metal strip S toward both ends in the width direction is provided in the pass-through guide member 7 b on the lower surface side of the pass-through device 7. 22 are drilled. Then, a high-pressure gas 21 such as compressed air is introduced into the chamber 7a of the plate passing device 7, and is injected from the gas injection port 22.

[0008] By forming the gas flow in this way, the central portion on the upper surface side of the metal band S in the passing plate becomes a negative pressure, and the metal band S is sucked toward the passing plate guide member 7b and floats while passing through the plate. Therefore, it is possible to stably pass the metal strip. On the other hand, the leading end of the metal strip to be continuously rolled, that is, the first end of the endless rolling, is a transfer table
Because it is transported while colliding with the 13 rolls, it is often greatly bent and warped. Therefore, if the sheet passing device 7 is lowered, the leading end of the metal strip is caught on the sheet passing device, and the sheet passing cannot be performed.

For this reason, as shown in FIG.
At the time of threading of the leading end Sa of the book, the threading device 7 is raised and retracted to the retracted position by using the elevating mechanism 20, and the top guide 5 is interposed between the introduction guide 6 and the threading device 7 to be greatly bent. The leading end of the metal band is guided and fed into the pinch roll 3. After feeding the first end of the metal strip in this way, the sheet passing device 7 is lowered to pass the sheet, thereby realizing the stable sheet passing as described above.

However, when passing the leading end of the first or batch rolled material in endless rolling, the leading end of the metal strip is particularly greatly bent as shown by a broken line in FIG. 5, for example. In such a case, the tip of the metal band may strike the corner of the top guide 5 and the tip may strike beyond the top guide, causing a trouble. A situation in which a coil having an unusual shape cannot be wound, that is, a so-called cold coil often occurs.

[0012] In particular, when a threading device is indispensable in order to stably pass a metal strip by floating it, a conventional top guide applied together with the vertically moving threading device has an interference with the elevating device. While avoiding the above problem, the metal strip is rotated and retracted in the direction in which the metal strip passes, so that the length of the guide portion cannot be sufficiently long, and the above-mentioned cold coil cannot be completely avoided.

The present invention is provided between a pinch roll disposed on the entrance side of a coiler and a threading device disposed immediately before the entrance side for threading a metal band. When feeding the leading end of the metal band into the coiler, the auxiliary guide for the top guide is provided along with the top guide that guides the leading end of the metal band and feeds it to the pinch roll in a state where the passing plate device is retracted to the retracted position. A guide portion inclined from the tip end of the top guide to the lower surface of the threading device at the retracted position, and a retracting means for retracting the guide portion in the width direction of the metal strip. The above-mentioned problem was solved by the auxiliary guide for the top guide which is a feature.

A preferred embodiment of an auxiliary guide for a top guide according to the present invention will be described with reference to FIG. FIG. 1A is a schematic side view, and FIG. 1B is a schematic front view. In FIG. 1B, the illustration is simplified by omitting the illustration of the pinch roll 3 and the introduction guide 5. The auxiliary guide 50 for the top guide of the present invention is arranged such that the guide portion 51 extends from the tip of the top guide 5 which is an existing facility to a position near the lower surface of the threading device 7 at the retracted position, and A retreating means 52 is provided on a beam 53 supporting the guide portion 51 so as to be able to move forward and backward.

Here, it is preferable to use a side shift cylinder such as an air cylinder or a hydraulic cylinder as the retracting means 52, but it is needless to say that other driving means such as a motor drive may be used. However, it is an essential requirement that after the first end of the metal strip is guided and fed into the coiler, the guide portion 51 is retracted to complete the evacuation before the threading apparatus starts descending to the pass line position. Here, as the passing device, a device that forms a gas flow from a gas injection port and floats a metal band as described above with reference to FIG. 4 is particularly preferable, but the passing device of the present invention is not limited thereto.
