Abstract
The present invention discloses a method, system and apparatus for use in a roll grinding machine. Data is read from an RFID tag automatically by providing an RF read/write sensor on a movable cylinder rod. The RF sensor is held away from the work roll area while the work roll is loaded or removed. When the work roll is placed in the position for grinding, a signal to rotate the roll is sent to the grinding machine, and also operates to advance the cylinder rod. An RFID tag embedded in the work roll and containing identification and other data related to the work roll, is read by a read/write sensor, and the data is then transferred from the sensor to a serial control interface, which converts the data and transmits the information to the grinding machine control desk and the computer control management data base. The work roll identification information is transmitted automatically to the grinding machine, eliminating errors in transposing information manually and avoiding potential injury to personnel from having to scan the RFID tag using handheld RF read/write modules.
