Definitions

  • the purpose of the ink rail 400 is to supply a predetermined amount of ink to the distribution ink drum 402.
  • the ink rail 400 is located in the aisle side of the unit and extends across the full width of the unit.
  • the rail is hinged so it can be pivoted for cleaning and maintenance.
  • the eight counters 80 are incremented by 2 kHz clock pulses until they reach the all ones condition. At this point the output of the counter 80 goes to a logic low voltage and it resets the R/5 flip-flop 81 or 82 to which it connects.
  • the output of each R/S flip-flop 81 or 82 control the operation of one of the solenoid valves 31 through power drivers 90 and 91 and, thus, each valve 31 is turned on when the flip-flops 81 and 82 are set, and they are each turned off as their associated counter 80 overflows and resets its R/S flip-flop.
  • the speed interface circuit 64 couples the digital incremented speed feedback signal received from the speed sensor 36 to the PIT 60.
  • the speed sensor 36 produces a logic high voltage pulse for each incremental movement of the web through the printing unit.
  • a magnetic sensor model 1-0001 available from Airpax Corporation is employed for this purpose, although any number of position feedback devices will suffice.
  • the speed sensor's signal is applied to a line receiver 95 which produces a clean logic level signal that is applied to the input of a 4-bit binary counter 96.
  • the counter 96 produces an output pulse each time sixteen feedback pulses are produced by the speed sensor 36.
  • the data structures which are employed by the preferred embodiment of the present invention to control the spray bars 26 are stored in the RAM 50.
  • An equivalent data structure is provided for the ink injector system and only the data structure for the spray bars will be described in detail.
  • these data structures are collectively referred to as the switch database 51 and the control database 52.
  • the structure of these two databases 51 and 52 are illustrated in FIG. 8 for one printing couple. Similar data is stored in the databases 51 and 53 for the other printing couple in the unit 10.
