Description

Apparatus for transferring coil

The present invention relates to a coil transfer device.

The production process of wire rod is generally produced through a series of processes such as wire-making, steel-continuous casting, rolling-winding-cooling-transfer. Particularly, changes in the wire structure and physical properties during the wire rod production process greatly vary depending on the cooling rate of the cooling zone after winding.

Generally, in the case of the spring steel wire, the cooling rate is cooled at the slowest possible rate in order to prevent cold tissues such as martensite and bait knight from coming out. However, due to the characteristics of the wire coil, temperature fluctuation occurs even in the same coil, and due to the cooling control limit in the air-cooling band relatively, there is a case where the transformation is partially completed and the coolant is deviated from the cooling zone.

If the transformation is not completed within the cooling zone, it may be locally quenched by contact with the draft and coil transfer device during transfer, resulting in a cold structure. Therefore, there is a need for a transfer device capable of preventing quenching during transfer of the coil after leaving the cooling zone.

An object of an embodiment of the present invention is to provide a coil transfer device for preventing a coil from being cooled by an external environment in a process of transferring a coil.

According to an aspect of the present invention, there is provided a coil transfer apparatus including: a horizontal table for supporting a coil; An upper pedestal arranged to be spaced apart from the horizontal stand and equipped with a heat insulating member capable of covering the coil; A roller member provided on the upper pedestal for winding or uncoiling the heat insulating member; A driving unit for rotating the roller member; And a shaft member connected to the driving unit, wherein the roller member includes a first roller member and a second roller member rotatably provided in the same direction, and the shaft member is rotatably supported by the first roller member and the second roller member, The shaft member and the roller members are rotated in opposite directions to engage with the roller member, and the heat insulating member can be configured to be wound or unwound according to the conveying position of the coil.

The coil transfer device according to an embodiment of the present invention can prevent the coils from being cooled by the external environment in the process of transferring the coils.

Generally, a wire coil (hereinafter referred to as a coil) is produced through a series of processes such as wire-making, steel-continuous casting, rolling-winding-cooling-transfer,

The coil is cooled in the cooling zone after winding, in which the texture and physical properties of the coil are changed according to the cooling rate of the cooling zone.

It is preferable to slow down the cooling rate of the cooling bed as much as possible in order to prevent cold structure from occurring in the cooling process of the coil. However, when the temperature fluctuation occurs in the cooling process, .

In this case, during the transfer of the coil, the coil may be partially quenched by the external environment, resulting in a low-temperature structure.

A coil transfer apparatus 100 according to an embodiment of the present invention includes a horizontal support 110 supporting a coil 200, an upper support 120 spaced apart from the horizontal support 110, And a roller member 125 for winding and uncoiling the heat insulating member 140. The coil member 200 is wound around the coil 200 by an external environment during the transfer of the coil 200. [ 200 can be prevented from being cooled.

Referring to FIG. 1, a process of transferring a coil 200 using a coil transfer apparatus 100 according to an embodiment of the present invention will be schematically described (in order from the left side in FIG. 1).

After the coil is wound, the coil 200, which has escaped from the cooling stand, is inserted into the coil transfer device 100 and is suspended.

Thereafter, the coil 200 is covered and covered by the heat insulating member 140.

When the coil transfer device 100 arrives at the test panel for inspecting the coil 200, the insulating member 140 is rolled up so as not to interfere with the test by the tester.

When the test piece is removed, the heat insulating member 140 is lowered again to cover the coil 200.

When the coil 200 is completely conveyed and the coil 200 is removed from the coil transfer device 100, the heat insulating member 140 is re-heated.

The sensing unit 160 senses whether or not the coil 200 is engaged with the coil transfer device 100 of the present invention, Thereby controlling the operation of the microcomputer 140.

The coil transfer device 100 of the present invention is provided with a sensor 170. The sensor 170 recognizes whether or not the coil transfer device 100 has arrived at the test platform and controls the operation of the heat insulating member 140 .

FIG. 2 is a schematic perspective view of a coil transfer apparatus according to an embodiment of the present invention, FIG. 3 is a schematic front view of an upper pedestal of a coil transfer apparatus according to an embodiment of the present invention, Fig. 3 is a perspective view of a horizontal base of a coil transfer device according to the invention;

The structure of the coil transfer apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG.

The coil transfer apparatus 100 according to an embodiment of the present invention includes a horizontal support 110, an upper support 120 disposed to be spaced apart from the horizontal support 110, a horizontal support 110 coupled to the upper support 120, (Not shown).

For example, the coil transfer device 100 according to an embodiment of the present invention may be a C-Hook hanger device for carrying the coil 200 by hooking it.

The horizontal bar 110 may be provided in a long bar shape so as to allow the coil 200 to be transported. The horizontal base 110 is a member that is in direct contact with the coil 200, so that the horizontal base 110 can be surrounded by the heat insulating material 180 for insulation (see FIG. 4).

The upper pedestal 120 is equipped with a heat insulating member 140 configured to cover the coil 200 for heat insulation. The heat insulating member 140 may be provided in the form of a heat insulating cloth.

The heat insulating member 140 is configured to be wound or unwound according to the position of the coil transfer apparatus 100 of the present invention.

For example, the upper pedestal 120 is provided with a roller member 125 for winding or uncoiling the heat insulating member 140.

The roller member 125 is connected to a driving unit 150 that transmits driving force. For example, the driving unit 150 may be a motor.

The upper pedestal 120 is provided with a shaft member 121 connected to the driving unit 150 and the shaft member 121 and the roller member 125 are engaged to rotate in opposite directions.

The roller member 125 can be rotated by the driving unit 150. Therefore, the heat insulating member 140 can be wound or unwound by the rotation of the roller member 125. [

The roller member 125 may include a first roller member 123 and a second roller member 124 mounted on the upper pedestal 120 so as to be spaced apart from each other.

The first roller member 123 and the second roller member 124 are rotatably provided in the same direction.

The thermal insulating member 140 is wound as the first roller member 123 and the second roller member 124 rotate in the clockwise direction and the first roller member 123 and the second roller member 124 are rotated counterclockwise The first roller member 123 and the second roller member 124 are respectively mounted so as to be released when rotated by the first roller member 123 and the second roller member 124, respectively.

Meanwhile, the upper pedestal 120 is provided with a guide member 126 for guiding the heat insulating member 140. Therefore, when the heat insulating member 140 is wound or unwound by the roller member 125, the heat insulating member 140 can be guided by the guide member 126 to stably cover the coil 200. [

The guide member 126 may be inclined with respect to the gravity direction.

The coil transfer device 100 of the present invention includes a sensing part 160 for sensing whether the coil 200 is engaged or not, a sensor 170 for recognizing the position of the coil transfer device 100, And a control unit (not shown) for controlling the driving unit 150 according to a signal transmitted from the sensor 170.

For example, the sensing portion 160 may be a strain gage, and the sensor 170 may be a proximity sensor.

The sensing unit 160 is mounted on one of the horizontal base 110, the upper pedestal 120, and the connecting base 130.

When the coil 200 is caught by the horizontal stand 110, the coil transfer device 100 is detected by the weight of the coil 200 to detect whether the coil 200 is caught in the coil transfer device 100 do.

The sensor 170 measures the distance from the structure located near the testing station to the coil transporting device 100 (for example, ), It can be recognized that additional work is required. The sensor 170 is mounted on one of the horizontal table 110, the upper table 120, and the connecting table 130.

The control unit may apply a driving signal to the driving unit 150 in response to a signal transmitted from the sensing unit 160 and the sensor 170 to wind or unroll the heat insulating member 140.

That is, the heat insulating member 140 can be controlled by a control unit (not shown) so as to be wound or unwound according to the conveying position of the coil 200.

5 is a flowchart illustrating a process of transferring a coil using a coil transfer apparatus according to an embodiment of the present invention.

First, when the coil 200 is inserted into the coil transfer apparatus 100 of the present invention, the signal is transmitted to the control unit (not shown) by the sensing unit 160.

For example, when the coil 200 is inserted into the coil transfer device 100, the coil transfer device 100 is deformed due to the weight of the coil 200. When the sensor 160 is a strain gauge By detecting such deformation, it is possible to recognize whether the coil 200 is inserted into the coil transfer apparatus 100 or not.

Here, if the predetermined limit deformation is exceeded, it can be recognized that the coil 200 is suspended from the coil transfer apparatus 100. [

A control unit (not shown) applies a driving signal to the driving unit 150 to rotate the roller member 125. Thus, the heat insulating member 140 is rotated by the driving unit 150, So that the coil 200 can be covered.

A control unit (not shown) applies a driving signal to the driving unit 150 so that the roller 200 is driven by the driving unit 150. In this case, when the coil 200 is conveyed while being covered with the heat insulating member 140, The member 125 is rotated so that the heat insulating member 140 is rolled up so as not to interfere with the test by the tester.

Here, whether or not the coil transfer apparatus 100 has arrived at the test section is detected by the sensor 170, and a signal is transmitted to the controller (not shown).

If the coil transfer apparatus 100 is moved away from the test section (or a structure near the test section), the coil 170 is moved by the sensor 170 to the coil transfer apparatus 100, The position of the heat insulating member 100 is recognized and a signal is transmitted to the control unit (not shown) so that the heat insulating member 140 is again lowered to cover the coil 200. [

Next, when the coil 200 is removed from the coil transfer device 100 after the completion of the transfer of the coil 200, this state is recognized by the sensing unit 160 and the insulating member 140 is wound up again.

Whether or not the coil 200 is removed from the coil transfer device 100 can be detected through the deformation of the coil transfer device 100. That is, since the coil transfer apparatus 100 with the coil 200 removed does not exceed the predetermined limit deformation, it can be recognized that the coil 200 is removed from the coil transfer apparatus 100.

According to the above embodiment, the coil transfer device 100 according to the embodiment of the present invention can prevent the coil 200 from being cooled by the external environment in the process of transferring the coil 200.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
