Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring a coil after winding in a rolling mill and an apparatus therefor.

[0002]

2. Description of the Related Art Winding by a coiler in a rolling mill,
For the method of transporting the coil after extraction, the winding shaft hole of the coil
(Hereinafter abbreviated as hole) up-end conveyance to send vertically,
There are two methods of down-end transportation, where the coil holes are sent horizontally. Conventionally, both the up-end transport and the down-end transport have been transferred to the transport conveyor by a dedicated up-ender or a transporter, respectively. FIG. 6 to FIG. 8 show such a situation, and FIG. 6 is a plan view showing the arrangement of an up-ender 6 for transferring the coil 4 from the down coiler 1 of the hot rolling line 3 to the up-end conveyor 2. FIG. 7 is an enlarged view as viewed from the direction indicated by the arrow A in FIG. Coil 4 wound by downcoiler 1
Shows a state in which the coil is disengaged from the winding shaft by the coiler 5 and transferred to the up ender 6, and is turned over by the up ender 6 (falling device) to change the state from the down end to the up end. In order to convey in the state of the down end, the coil 4 wound by the down coiler 1 is detached from the winding shaft by the coil cap 5 as shown in FIG.
The coil 4 on the coiler 5 is gripped by the trumpo 7 and placed on the up-end conveyor.

[0003] Both up-end conveyance and down-end conveyance have advantages and disadvantages, and there is a problem in that when the coil is conveyed in the up-end state, flaws are easily formed. The main factor is that if the edges of the steel sheet are not aligned during coil winding, the plate in the uneven part will be broken (ear breakage) at the time of up-end, making the product unsuitable. This is more likely to occur as the plate thickness is smaller. When the coil is wound up and the above-mentioned irregularity and the loosened portion are in the up end, the plate is rubbed, scratched, and becomes unsuitable as a product. This is likely to occur in the inner and outer windings of the coil. Conversely, when the coil is transported in a down-end state, there is a problem that the coil wound at a high temperature is crushed by weight and deformed.

[0004]

From the above situation, there are cases where it is better to convey in an up-end state by a coil and cases in which it is better to convey in a down-end state. Two types of equipment are required: upenda and trumpo. In the present invention, this waste is eliminated, and a transport system suitable for up-end transport and down-end transport is arbitrarily selected to enable both types of transport with one apparatus.

[0005]

As a result of examining the above-mentioned problems, regarding the coil conveyance after winding of a steel sheet manufactured by hot rolling, the coil wound by a down coiler is removed by a coiler or the like, and then transferred to a conveyor. When posting
A coil suitable for transporting the coil conveyor at the up-end by the same overturning device is turned over with the direction of the hole of the coil perpendicular to the transport surface of the coil conveyor, and the coil conveyor at the down-end. After the coil suitable for transport is turned 90 °, the coil hole is turned over horizontally with respect to the transport surface of the coil transport conveyor, and both up-end and down-end transfer are performed. And a coil transfer method characterized by mounting.

In addition, a coil cap and a tipping device are arranged between the down coiler and the coil conveyor, and the coil cap is provided with a running wheel at a lower portion of the main body and a coil loading portion at an upper portion so that the coil can be loaded and traveled. In a coil transfer device in which a main body having a coil support portion at the upper portion for receiving a coil is supported at a lower portion and is capable of being turned over, the coil is turned in a horizontal plane to a coiling cap, a fixed skid between the downcoiler and the overturning device, or a overturning device A coil transfer device provided with a turning means and capable of transferring both up-end and down-end types. Here, the fixed skid is a temporary mounting table for changing the direction of the coil.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The arrangement of a coil coiler and a tipping device between a downcoiler and a coil conveyor is substantially the same as the example shown in FIG. 6, so that the illustration is omitted. In the present invention, by a special fall device,
As shown in FIGS. 1 and 2, a single unit enables both up-end and down-end transport systems. As shown in FIG. 1, the overturning device 11 has a main body 13 supported by a shaft 12 rotatable by 90 ° and a coil holding unit 15 that receives the coil 14 from a coil cap when standing up (left side in the drawing).
