AI Technical Summary
Existing digital printing presses have difficulty effectively compensating for deviations in the diameter of the alignment rollers caused by manufacturing defects or wear during the printing process, which affects the accurate alignment of printed pages.
In the alignment station, a first sensor is used to detect the pages and align them with the alignment roller. A second sensor is used to detect the page position again in the printing station entrance area. The signal is input to the adjustment circuit to correct the alignment station. Precise alignment is achieved by asynchronously driving the alignment roller and slider to move laterally.
By using sensor detection and adjusting the circuit for correction, the diameter deviation of the alignment roller can be effectively compensated, ensuring accurate alignment of printed pages and improving printing quality.
