US 6,233,501 B1 · System for engraving a plurality of gravure rolls

Abstract

A gravure engraving system that capable of successively engraving each of a plurality of gravure cylinders through no intermediary of a manual operation, includes a transport device for transporting a gravure cylinder. The transport device is disposed between an engraving machine for engraving the circumferential surface of a gravure cylinder and a stock device which stores a plurality of gravure cylinders. A predetermined gravure cylinder is selected out of the gravure cylinders stared in the stock device and transported to the engraving machine by the transport device. After the transported gravure cylinder has been automatically set on the engraving machine, the gravure cylinder is engraved. Thereafter, the transport device transports the engraved gravure cylinder to the stock device where the engraved gravure cylinder is stored.

Dependent claims

A gravure cylinder transport device comprising:

an arm for supporting a gravure cylinder from below and placed such that an axis thereof extends horizontally;
a drive device for moving said arm in an up-and-down direction in which the gravure cylinder is moved vertically, in a horizontal transport direction orthogonal to a gravure cylinder axial direction, and in the gravure cylinder axial direction;
a sensor disposed at said arm for detecting an end surface of the gravure cylinder;
a measurement control for controlling said drive device before the gravure cylinder is held by said arm, such that said arm is moved in the gravure cylinder axial direction and then stopped when said sensor has detected the end surface of the gravure cylinder;
and
a calculation for calculating a length of the gravure cylinder as a function of a behavior of said arm.
