Abstract

PURPOSE:To prevent the occurrence of a winding collapse flaw in the direction of the width of a coil during conveyance of a coil by a method wherein a vertical elevation type transfer conveyor is located between first and second conveyors and a difference in a level between the conveyors is eliminated through elevation operation of the vertical elevation type carrier conveyor. CONSTITUTION:A vertical elevation type carrier conveyor 4 is located between first and second conveyors 2 and 3. After through raising of the vertical elevation type transfer conveyor 4, the carrier conveyor is positioned flush with the first conveyor 2, a coil 1 is placed on the vertical elevation type transfer conveyor 4 through a caul 5 by rotationally driving the belt rotating body 6 of the first conveyor 2 with the aid of a motor 7. With this state, the vertical elevation type transfer conveyor 4 is lowered and kept flush with the level of the second conveyor 3 and the coil 1 is transferred to the second conveyor 3. This constitution prevents the occurrence of the scratch flaw of the coil 1 without winding collapse in the direction of width of the coil 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil transfer device for transferring a coil having an inclined portion.

[0002]

2. Description of the Related Art Conventionally, conveyor transfer is used to convey hot rolled coils and the like. Also, when changing the transfer course in the conveyor transfer of this coil, different conveyors are crossed, a transfer device is provided at the intersection, and once transferred to this transfer device, it is transferred again to the next conveyor. Is normal. That is, the first carrying coil
There is known a device that transfers a coil from a conveyor to a second conveyor by a transfer device. Furthermore, when transferring the coil to a storage place with an inclination by a conveyor,
As shown in FIG. 4, while the coil 1 is placed on the conveyor 2, the flat portion 11 passes through the inclined portion 12 and the flat portion 11,
Further, the coil is conveyed again in the state of the flat portion 11 through the sloped portion 12 of the uphill. That is, FIG. 4 is a diagram showing a conventional coil transport state to a place having a height difference.

[0003]

As described above, in transferring the coil to the conveyor, it is necessary to use the downhill and uphill conveyors as shown in FIG. 4 when transporting the coil to a place having a height difference. Therefore, the coil in the inclined portion having a vertical gradient is conveyed in a state with a gradient, so that the load variation in the coil occurs, which causes a winding deviation in the coil width direction. There is a problem that the winding deviation causes a flaw in the coil during conveyance.

[0004]

In order to solve these problems, the present invention employs a vertically elevating type transfer conveyor at a place where a height difference is generated to eliminate a slanted portion, so that the coil is conveyed during coil conveyance. (EN) A coil transfer device for the purpose of preventing winding deviations in the coil width direction. The gist of the invention is that in a coil transfer device for transferring a coil having an inclined portion, a vertical elevating transfer conveyor is disposed between a first conveyor and a second conveyor, and the vertical elevating transfer conveyor is There is provided a coil transfer device characterized in that a height difference between conveyors is eliminated by lifting and lowering operations to prevent winding slip flaws in the coil width direction during coil transfer.

[0005]

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a side view of a coil transfer device according to the present invention. 2 is a plan view of the coil transfer device according to the present invention. As shown in FIG. 1 and FIG. 2, when performing coil transfer with a height difference between the first conveyor 2 that conveys the coil 1 and the second conveyor 3, between the first conveyor 2 and the second conveyor 3 It is necessary to transfer the coil 1 from the first conveyor 2 to the vertical elevating transfer conveyor 4 by arranging the vertical elevating transfer conveyor 4 in the.

Therefore, when the coil 1 is transferred to the vertical elevating transfer conveyor 4, the vertical elevating transfer conveyor 4 is first raised to the position of the first conveyor 2 so that the position of the first conveyor 2 becomes horizontal. After the first conveyor 2
The first conveyor 2 when the coil 1 being conveyed reaches
After stopping the conveyance of the upper coil 1, and confirming that there is no deviation between the stopped coil 1, the center position and the vertical elevating transfer conveyor 4, the contact plate 5 is vertically elevating transferred to the first conveyor 2. After placing a floorboard between both conveyors 4, the first conveyor 2
The belt rotating body 6 is driven to rotate by the motor 7 and placed on the vertical elevating transfer conveyor 4 via the contact plate 5.

In this state, the vertical elevating transfer conveyor 4 is lowered and stopped at the position of the second conveyor 3 to maintain the position of the second conveyor 3 in a horizontal state. After laying a plate between the conveyors 3 in the same manner as described above, the belt rotating body 6 of the vertical elevating transfer conveyor 4 is driven by the motor 7. The movement amount of the conveyor at this time is measured by the pulse generator 8 and then operated. Then, the coil 1 is transferred to the second conveyor 3 placed at a low position. After transferring to the second conveyor 3, the second conveyor 3
The belt rotating body 6 of is driven to rotate by the motor 7,
Transfer in low position is performed.

FIG. 3 is a view showing an elevating mechanism of a vertical elevating type transfer conveyor according to the present invention. As shown in FIG. 3, the vertical elevating transfer conveyor 4 is provided in the lifting device body 9, and the lifting device 10 is installed in the lifting device body 9 by a hydraulic pressure or an electric motor so that the lifting device 10 lifts or lowers the lifting device 10. It is configured to be possible. Further, the vertical elevating transfer conveyor 4 is similar to the driving of the first conveyor 2 and the second conveyor 3 in that the position and the amount of movement of the coil 1 are determined by the pulse generator 8.
The control signal is sent to the motor 7 by the two-conveyor drive controller and is driven.

[0009]

As described above, by transferring by the vertical elevating type transfer conveyor according to the present invention, even when transferring to a place having a height difference, it is possible to transfer without a gradient in the coil transfer during the transfer, so that the conventional transfer can be performed. As compared with the coil transportation which had a gradient, there was no winding collapse in the coil width direction and there were no scratches on the coil, and it was possible to perform transportation of extremely excellent quality.
