Automatic roll data acquisition system
First Claim
1. A system for acquiring data from a passive memory device for use in an automated roll grinding machine comprising:
- said passive memory device having data stored thereon associated with a roll to which said passive memory device is attached;
reading means for reading data from said passive memory device communicatively coupled with a controller for digitally controlling a roll grinding machine; and
positioning means for movement of said reading means from a retracted position to an extended position adjacent to said passive memory device, said controller being programmed to sense that a roll is positioned within said roll grinding machine, and to extend said positioning means into a position proximate said passive memory device;
and to return to a retracted position upon completion of the data reading function.

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.

18. A system for use in a computer-controlled roll grinding machine comprising:
-
a) providing a work roll with at least one passive memory storage device;
b) storing data on said passive memory storage device related to the work roll to which it is attached;
c) positioning said work roll within a support frame in the grinding machine for measurement and grinding;
d) rotating said work roll in said support frame;
d). verifying that the work roll is in the desired position for grinding;
e) advancing a reading means toward the memory storage device within a spacing sufficiently proximate to said memory storage means for communication to occur between said memory storage device and the reading means;
f) accessing said data from the memory storage means;
g) communicating said data to a computer associated with the grinding apparatus for controlling said grinding apparatus;
h) acknowledging receipt of said data to an operator associated with said grinding apparatus; and
i) retracting said reading means to a position away from the support means to provide clearance for removal and replacement of the workpiece.
