The present invention relates to a coil side calibrating device for calibrating a telescope, when a telescope is generated, from a side of a coil product, which is the final product produced in a steel mill, and more particularly, And more particularly to a coil side calibrating device capable of simultaneously calibrating a telescope.

Generally, it is often the case that normal coil products are not formed in the course of coiling strip products produced in steel mills. For example, a side surface of a coil does not form a plane, but a plurality of defects such as a cone-like shape are continuously protruded to form a cone-like defect. Since the shape of such a defect is similar to the overlapping shape of the telescope of a folding telescope, do.

Such a telescope is mainly generated at the beginning or end of the coil to be formed, so it is generated on the inner diameter side or the outer diameter side of the coil when the coiling of the strip is completed.

Conventionally, if defects of the telescope are generated on the side of the completed coil after completion of the coiling of the strip, calibration work by the force before the final packaging operation is performed. That is, when a telescope is generated on the side of the coil wound around the strip in a tension leveler (not shown) that winds the strip in the form of a coil, at least two workers are needed to calibrate the side shape of the coil.

The manual operation by the operator is performed by striking the telescope portion with a heavy hammer when the coil, which is moved by the lift, comes to the packaging operation position and stops at first. At this time, in order to prevent the side of the coil from being damaged by the striking operation, another worker installs and supports each part to be calibrated.

However, such a correction operation causes the following problems.

First, a worker who supports a tree when hitting by a heavy hammer is exposed to the risk of a safety accident.

Second, due to the impact generated when the hammer strikes, the coil can fall off from the lift hook and fall down.

Third, if the telescope generation is severe or the thickness of the strip is thick, the hammer blowing may not effectively correct the telescope portion.

Fourth, when the hammer strikes, the damaged part of the blade is introduced into the coil through the space formed on the side of the coil, thereby causing a quality defect of the coil product.

Therefore, there is a need for a coil side calibrating device capable of solving the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a calibrating device capable of calibrating a coil side where a telescope is generated simply and effectively in a safer state by an operator.

In order to achieve the above object, according to the present invention, a coil side calibrating apparatus having a workbench for calibrating a side surface of a coil where a telescope is generated is provided with a coil side calibrating device, which is installed on both sides of the workbench, A fixed frame having a plurality of guide bars coupled at one end thereof to the support frame and extending rearwardly of the support frame, and a plurality of guide rings into which the guide bars are slidably inserted; And a cylinder fixed to the stationary frame, the cylinder being connected to the rear of the support frame so that the support frame can move toward the work station, wherein the support frame is reciprocated in the direction toward the work station Guided by the guide bar to move, By the operation, it characterized in that the plate-like member to the side of the correction coil by pressure on the side of the coil.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The coil 22 having completed the winding operation of the strip is conveyed to the subsequent process along the working beam 1. [ At this time, when a telescope is generated on the inner diameter side and / or the outer diameter side of the coil 22 in which the winding work has been completed, the coil 22 is moved by the lift hook 17 to the work table 19 ).

According to the present invention, the coil side calibrating device includes a plate-shaped member 9 located on both sides of the work table 19. [ The plate-shaped member 9 is supported on the stationary frame 13 so as to be reciprocally movable toward the work table 19. One end of the guide bar 14, which is slidably inserted into the guide ring 20 mounted on the fixed frame 13, is fixed to the support frame 12 at the rear side of the plate- And is coupled to the frame 12.

The fixed frame 13 is provided with a cylinder 15 which is operated to expand and contract so that the plate-shaped member 9 can reciprocate toward the workbench 19. That is, the main body of the cylinder 15 is fixed to the fixed frame 13, and the end of the cylinder rod 16 is connected to the support frame 12. Thus, the cylinder rod 16 is advanced toward the work table 19, so that the plate member 9 approaches the work table 19.

The operation of the coil side calibrating device according to the present invention is made by the above-described configuration, and the operation is described below.

As shown in Fig. 5, the body frame 10 is provided on both sides with respect to the coil 22 wound on the body. That is, on the fixed plate 11 fixed to the ground, a main frame 10, to which the support frame 12 and the fixed frame 13 are assembled, is fixedly installed.

A guide ring 20 is fixed to the square corner portion of the fixed frame 13 and the guide bar 14 is slidably inserted into the guide ring 20. [ A support frame 12 is attached to the front surface of the guide bar 14 and the cylinder 15 is fixed to the upper side of the fixed frame 13 by the movement of the support frame 12.

Therefore, the rod 16 of the cylinder 15 is configured to be assembled to one side of the rear surface of the support frame 12. [

At this time, a structure, for example, a plate-shaped member 9 is provided on the outside of the support frame 12 so that the side surface of the wound strip coils 22 can be temporarily depressed. By the action of the cylinder 15, The frame 12 can reciprocate.

In order to efficiently transmit the force of the cylinder rod 16 to the support frame 12, it is preferable that a plurality of rigid reinforcing bars 24 are attached to the rear surface of the support frame 12.

A space 25 is formed on the upper side of the support frame 12 and the plate member 9 so that the lift hook 17 can be freely separated from the coil 22 mounted on the work table 19, As described below, an unlocking plate 23 is provided to protrude below the edges of the frame 12 and the plate member 9 to prevent the coils from being unwrapped during the calibration work on the side of the coil.

A rectangular shaped groove 32 for mounting the touch bar 27 described below is formed in the lower portion of the support frame 12 and the plate member 9 and the support frame 12 and the plate- 9 are formed with circular holes 31 for installing at least two proximity sensors 26a described below. That is, the first proximity sensor 26a is fixed to the circular hole 31 by the first bracket 33a provided in the rear of the circular hole 31, and the touch bar 27 is disposed in front of the plate- And is fixed to the support frame 12 so as to be reciprocally movable in a state of being elastically supported by a spring 29 in a state of passing through the rectangular groove 32 so as to protrude forward from the surface. A second proximity sensor 26b for detecting the operation of the touch bar 27 is fixed to the support frame 12 by the second bracket 33b.

Hereinafter, the operation and effect of the present invention will be described in detail.

The winding 22 is completed and the telescopic coil 22 is moved up on the work table 19 by the lift hook 17. On both sides of the coil 22 mounted on the worktable 19, a fixed frame 13 assembled to the body frame 10 is provided.

The support frame 12 assembled to the stationary frame 23 advances by the advance of the cylinder rod 16 by the operation of the cylinder 15 and approaches the coil 22 mounted on the work table 19 . The guide bar 14 having one end fixed to the support frame 12 is inserted into the guide ring 20 attached to the stationary frame 23 and can reciprocate left and right while supporting the support frame 12. [ .

Therefore, the cylinder rod 21 and the guide bar 14 reciprocate the support frame 12 integrally. In such a situation, the support frame 12 is gradually moved to both sides of the coil 22 mounted on the work table 19, so that the plate member 9 presses both sides of the coil 22.

On the other hand, the release preventing plate 23 covers the end portion of the coil 22 so that the coil 22 is released when the band 34 for maintaining the wound state of the coil 22 is broken during the coil side surface correcting operation Thereby preventing the peripheral equipment from being damaged by the uncoiled coil or from being injured by the operator.

The overall operation of the embodiment according to the present invention is configured to be performed by a sensor and automatic control installed in each part of the apparatus.

That is, when the operator operates the coil side calibrating device, the touch bar 27 protruded from the support frame 12 during the advance of the plate-like member 9 toward both sides of the coil 22 by the operation of the cylinder 15 When the touch bar 27 comes into contact with the telescope formed on one side of the coil, it pushes the spring 29 in. The operation of the touch bar 27 is detected by the second proximity sensor 26b and the operation of the cylinder 15 is stopped to stop the advancing operation of the plate-shaped member 9. [

Thereafter, only the support frame 12 on the side not yet in contact with the side surface of the coil is advanced. At this time, when the first proximity sensor 26a senses the side of the coil maintained in the steady state, the advance operation of the support frame 12 is stopped. Then, when the telescope detects the side of the coil, the support frame of the side on which the telescope is sensed is advanced, while gradually pushing the telescope until the second proximity sensor 26b detects the side of the coil, and when the proximity sensor 26b senses the side of the coil, The operation is stopped to stop the calibration operation on the coil side.

When the plate member 9 completes the calibration operation for the coil side due to the operation of the cylinder 15 as described above, the above operation is performed in the reverse order so that the plate member 9 returns to the initial position, Is moved to the working beam (1).
