Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil transfer apparatus for transferring a coil to a coil conveyor after winding the coil by a down coiler in a rolling mill.

[0002]

2. Description of the Related Art In a rolling mill, a coil is taken up and taken out by a down-coiler, and an up-end conveyance in which a coil winding shaft hole (hereinafter abbreviated as a hole) is sent vertically is performed. Conventionally, in order to perform this up-end transfer, a coil is transferred to a transfer conveyor using a dedicated up-ender.

FIGS. 5 and 6 show such a situation. FIG. 5 is a plan view showing an arrangement of an upender 6 for transferring the coil 4 from the down coiler 1 of the hot rolling line 3 to the coil conveyor 2 in an upend state. FIG. 6 is a side view for explaining the operation of the upender. FIG. 6 shows a state where the coil 4 wound by the down coiler 1 is detached from the winding shaft by the coil car 5 and transferred to the up ender 6, and is turned over by the up ender 6 to change from the down end state to the up end state. ing.

[0004]

However, when the coil is transported in the up-end state, there is a problem that the coil is apt to be damaged. The main causes of flaws during transport in the up-end state are shown below. If the edges of the steel plate are not aligned during coil winding (Telescopic), the plate at the uneven portion is 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.

[0005] When the coil is wound up and the above-mentioned irregularity and the winding loosened portion are at the up end, the plate rubs,
Scratches make the product ineligible. This is likely to occur in the inner and outer windings of the coil. In order to avoid the generation of the flaws as described above, it is desirable to transport the coil in a down-end state in which the hole of the coil is sent horizontally.

However, in order to transport the coil in the down-end state, as shown in FIG. 7, the coil 4 wound by the down coiler 1 is removed from the winding shaft by the coil car 5 and the coil 4 on the coil car 5 is removed. And a transporter 7 for gripping and loading the coil on the coil conveyor 2 is required. However, the trampo running on the ceiling of such a line is a very large facility, and large-scale remodeling of the line is necessary to apply the trampo to the existing line assuming up-end transport. In some cases, the line layout needs to be changed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coil transfer device which can minimize the remodeling of an existing line, which has conventionally been used for up-end transport, and which can be remodeled with the same layout as the conventional one.

[0008]

According to the present invention, a coil car for receiving and conveying a coil from a down coiler and a coil transfer machine for receiving and transferring the coil from the coil car to a coil conveyor are arranged between the down coiler and the coil conveyor. The coil car is provided with a running wheel provided at a lower portion of the main body and a coil loading portion provided at an upper portion so that the coil can be loaded and run, and the coil transfer device is a coil transfer device having a coil support portion receiving a coil from the coil car at an upper portion, The coil transfer machine is provided with a turning means for turning the coil received by the coil supporter in a horizontal plane, and a lifting means for lifting and lowering the coil, so that the transfer can be performed in a down-end manner. The above problem was solved by the transfer device.

[0009] In order to carry out the transfer in the down-end state on the coil conveyor, the V
Although it is necessary to provide a coil receiving base called a slat, it is possible to easily cope with this with a minimum modification of the coil conveyor that performs the transfer in the existing up-end state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a coil transfer machine applied to a coil transfer device of the present invention will be described with reference to FIG.
As shown in FIGS. 2A and 2B, a coil transfer machine 10 applied to the coil transfer device of the present invention has a function of receiving and supporting the coil 4 by a coil supporter 11 from a coil car (not shown). .

As shown in FIG. 2 (c), the coil transfer machine 10 applied to the coil transfer device of the present invention has a turning means for freely turning in a horizontal plane. As shown in FIG. 2 (d), there is also provided an elevating means which moves up and down. Next, based on FIG.
The operation of the coil transfer device when the coil transfer device described above is applied to the coil transfer device of the present invention will be described.

The coil 4 transported by the coil car 5
Is fitted into the coil supporting portion 11 of the coil transfer machine 10 (FIG. 1A). Next, the coil loading section of the coil car 5 descends, and the coil 4 is deposited in the coil support section 11 (FIG. 1).
(B)). The coil transfer machine 10 in which the coil 4 is deposited in the coil supporter 11 first makes a 90 ° turn in a horizontal plane, and then descends to load the coil 4 on the coil transfer line 2 (FIG. 1 (c)). )).

Here, V slats are provided on the coil transfer line 2 at predetermined intervals in advance corresponding to the down-end transfer of the coil. Modification to install the coil transfer machine described above in place of the conventional up-ender and to install V slats on the coil transfer line,
Since the line can be modified minimally and can be dealt with by simple modification of the existing line, it can be implemented easily and simply.

FIG. 4 is a plan view of a line to which the coil transfer device of the present invention is applied. It should be noted that the same function as described above can be achieved by holding and transferring the lower portion of the coil with the coil receiving portion 12 as shown in FIG. 3 instead of carrying the coil on the coil supporting portion as described above. It goes without saying that it can be done.

[0015]

By applying the coil transfer device of the present invention, down-end transportation can be easily performed with minimal remodeling in a line that has conventionally performed up-end transportation. As a result, the coil was not flawed and became unsuitable as a product, and the product yield was greatly improved.
