Description

First, to measure the direction and the inclination of the rotation axis of the roll at the same time to be able to match the parallel and inclination between the rolls more quickly.

Secondly, the use of the measuring device is to determine whether the measuring device is accurately seated on the outer surface of the roll to enable more accurate adjustment of the parallel and inclination between the rolls.

Third, when the parallelism and the inclination between the reference roll and the other roll do not coincide with each other, a signal is generated to enable more convenient adjustment of the parallelism and the inclination between the rolls.

Fourth, it is intended to be able to mount the measuring device in the correct position on the roll by using various auxiliary jig according to the size of the roll.

Roll alignment measurement method (hereinafter referred to as "roll alignment measurement method") using a precision measuring device of an embodiment of the present invention is a plurality of roll alignment measurement method as shown in Figure 5 according to an embodiment of the present invention S1 step of measuring the rotation axis direction of one of the rolls, S2 step of measuring the rotation axis direction of the other roll of the plurality of rolls, and the rotation axis direction of one roll measured in step S1 and the other rolls measured in step S2 When the rotation axis direction of one roll measured in the step S1 and the rotation axis direction of the other roll measured in the step S2 do not coincide with each other by comparing the direction of the rotation axis, it is preferable that the step S3 is performed to generate an event in the display 110. .

Step S1 is a reference roll rotation axis direction measurement step to set the reference roll to adjust the parallel and horizontal between the rolls, and by placing a precision measuring device on the reference roll to measure the direction value of the rotation axis of the reference roll.

When the direction value of the reference roll is measured, a precision measuring device is placed on the reference roll and the roll adjacent to the reference roll to measure the direction value, and until the direction value of the reference roll matches the direction value of the adjacent roll, Adjust the axis of rotation.

In this case, the roll alignment device displays an event that the direction of the roll does not match on the display device when the direction value of the roll adjacent to the reference roll does not match to induce parallelism between the adjacent roll and the reference roll.

In addition, when the pressure measuring sensor is provided in the precision measuring device according to an embodiment of the present invention, in step S1, the position of the reference roll detected by the pressure sensor 123 is symmetric with respect to the seating upper line 121. If not, further comprising the step S1a for generating an event in the display 110, in step S2 the position of the roll adjacent to the reference roll detected by the pressure sensor 123 is based on the seating upper line 121 If it is not symmetrical may further include the step S2a for generating an event in the display 110.
