Mass mailing control

Mass mailings require letters to be sorted and then stacked and banded by destination (town/district, street). Output is managed and monitored via ECC200 datamatrix-codes printed into the address field. Image acquisition is triggered by a sensor signal. The image processing system scans the DM-code, identifying 6 control bit symbols as well as a consecutive 2-character index number from its character string. Based on these control bits, a digital signal is sent to the banding machine control unit to bind a stack of letters. Consecutively increasing index numbers are monitored. The image processing system identifies sequence errors, archives them and sends data to the control unit to remove these letters from the process. 8 letters per second are controlled and banded at a speed of 1m/s.
