The present invention relates to a device for calibrating a telescope of a coil, and more particularly, by calibrating a telescope by allowing the inner and outer telescopes to be uniformly pressured by being moved up and down in accordance with the coil specification. The present invention relates to a telescope calibration apparatus of a coil that can be performed precisely.

In general, when the steel sheet is wound with a coil, the inner portion and the outer portion are protruded as compared to other portions, and so-called defect sites called telescopes are generated, and a conventional apparatus for correcting this telescope is shown in FIG. Schematically shown.

However, in the above-described conventional apparatus, the height of the cylinder 91 and the quartz plate 92 connected to the cylinder 91 is always maintained at a constant position, while the outer diameter of the coil C is variously formed. Due to the difference between the center of the 91 and the quartz plate 92 and the center of the coil C, the pressure exerted through the quartz plate 92 is unevenly formed, which uniformly corrects the telescope of the coil C. It is impossible to have a problem.

In addition, in the related art, the degree of occurrence of the telescope formed in the coil is directly measured and judged by the naked eye or at right angles, and thus, the operation is in close proximity to the facility, and thus the risk of safety accident is exposed. In addition, measurement and judgment differed depending on the skill of the work.

In addition, since the means for supporting the outer edge end of the coil (C) is not provided at all, the thickness of the steel sheet is thick, the outer portion telescope calibration itself is impossible, such as a large amount of unrolled outer portion during telescope calibration.

The components are configured to be controlled by a facility control computer (not shown), in which a predetermined program is input in advance so that each component can be controlled by signals provided from sensors.

The operation of the present invention having the above configuration will be described.

When the coil C arrives at the saddle S of the conveyor, the coil outer diameter sensor 18 installed at the center lower surface of the frame F measures the outer diameter of the coil C and transmits it to the facility control computer. By this data, the facility control computer drives the vertical cylinder 21 and raises the vertical movable table 22 connected thereto.

Along with the vertical movable table 22, the horizontal movable table 23 mounted thereon is also raised, and when the center of the reel 24 mounted on the horizontal movable table 23 and the coil C coincide with each other, As the cylinder 21 is stopped, the lift of the horizontal movable table 23 is stopped.

After the vertical cylinder 23 is stopped, the cylinder 22b of the vertical carrier 22 is moved forward to move the horizontal carrier 23 toward the coil C, whereby the horizontal carrier 23 The disk 25 fixedly mounted to the inner side of the coil corrects the telescope while pressing the side of the coil C.

Of course, the disc 25 is moved while calibrating the inner winding side telescope of the coil C, and then the sensing sensor 25b installed on the disc 25 is in contact with the side of the coil C and at the same time the cylinder 22b is stopped, and the movement of the horizontal platform 23 and the disk 25 provided thereon is stopped.

After the driving of the cylinder 22b is stopped, the cylinder 24a of the horizontal movable table 23 is driven forward to insert the reel 24 in the center of the coil C, and the reel 24 is a coil ( When fitted to the center of the C) to expand the outer diameter of the reel (24).

After the expansion of the reel 24 is completed, if the vertical cylinder 21 is further raised to a predetermined height, the coil C is also elevated to the saddle S by a predetermined height.

At this time, the disc 25 is moved away from the coil 24 by slightly retracting the cylinder 24a.

Further, the vertical cylinder 21 is further raised, and at the same time, the arm 17 is rotated by advancing the cylinder 17 installed in the movable body 12 of the frame F, and the arm 15 is rotated. As a result, the snubber roll 16 is rotated and lowered to press the outer surface of the coil C to prevent the outer edge end of the coil C from being loosened.

Subsequently, the cylinder 26a provided in the disc 25 is driven forward to move the rod 26 connected thereto in the radial direction of the disc 25.

Subsequently, when the cylinder 24a, which has been slightly reversed, is advanced again, the disc 25 connected to the cylinder 24a and the rod 26 radially moved to the disc 25 are directed toward the coil C. By approaching and pressurizing the coil C, the inner cylinder side telescope of the coil C is once again calibrated by the disc 25 and at the same time the outer telescope of the coil C is calibrated by the rod 26. .

In particular, when a telescope in which the outer peripheral end of the coil C is biased toward one side is generated, the movable body 12 supporting the snubber roll 16 is driven by the driving motor 11c. The outer winding end is moved in a direction opposite to the biased direction, and the snubber roll 16 is moved with the movement of the movable body 12 to return the outer winding end of the coil c to its normal position.

When the above-described inner and outer telescope calibration work of the coil C is finished, the facility control computer checks the telescope calibration of the coil C, and the discs 25 each of the coils C The width of the coil C is calculated by the sensor 37 provided in the telescope measuring unit 30 and the width of the coil C is calculated by calculation in a facility control computer. It is possible to determine whether or not the telescope of the coil C is calibrated normally by the difference between the width of the coil and the width of the set coil C.

As described above, according to the telescope calibration apparatus of the coil according to the present invention, the inner winding side telescope of the coil is calibrated by the disc moved toward the coil and the outer winding side of the coil by the rod moved in the radial direction of the disc. By calibrating the telescope, the inner and outer telescopes of the coil can be calibrated more effectively.
