Zusammenfassung: | An apparatus and a method for measuring the concentric and right/left balance of a roll are provided to measure the concentric and right/left balance of the roll with a laser displacement sensor and an angle encoder, thereby diagramming the concentric of the roll numerically and minutely. An angle encoder(232) measures the rotation angle of rolls(210,240). A laser displacement sensor(234) emits laser beam toward the center of the rolls and receives the laser beam reflected from the surface of the rolls. The laser displacement sensor obtains the surface distance data of the rolls. A controller(250) is connected to the angle encoder and the laser displacement sensor by wire or wireless. The controller computes the displacement which is the change of surface distance data according to the rotation angle of the measured rolls. |
