Abstract
Heights of components or parts thereof are measured within a printing machine by measuring their relative rather than absolute heights. A virtual surface may be constructed from the measured heights, with a tolerance level employed based on the virtual surface. The invention is particularly suited to measurement of tooling components within a printing machine, such as tooling pins.
Claims20
A component height sensing system for a printing machine, comprising:
- a height sensor operative to measure the relative heights of at least three component locations relative to the height sensor and output measured relative height information, and
- a control means for receiving the measured relative height information from the height sensor and determining, from the received relative height information, the heights of each of the at least three component locations relative to the others of the at least three component locations.
A method of determining height deviations of component locations within a machine, comprising the steps of:
- i) using a height sensor to measure the relative heights of at least three component locations relative to the height sensor,
- ii) determining, from the measured relative heights, the heights of each of the at least three component locations relative to the others of the at least three component locations, and
- iii) identifying height deviations of any component locations by analysing the heights of each of the at least three component locations relative to the others of the at least three component locations determined in step ii).
