Automation  
Press automation is based on the networking of multiple printing units. All machine functions for the complete press configuration can be accessed via Touch Screen on Central Console. Parallely the machine functions can also be controlled locally through MMI provided on the local station.
Hardware :
  • Siemens make DC Digital Drive for powering up the main DC motor.
  • Seimens make (S7-200) local PLCs control all machine functions locally.
  • Siemens make MMI is used for operation of all local machine functions.
  • Siemens make (S7-400) PLCs is used as master pocessor to process the centralized data for machine function controls as well as to carry our all fast synchronization and data transfer functions with local print units through local PLCs.
  • Siemens make color touch Screen is used on Central Console.
Controls :
  • Ink / water balance using three standard curves.
  • Changing the pagination by enabling / disabling the desired print units / towers.
  • Registration Control through Touch screen on the Central Console
  • Centralized Machine lubrication system control and monitoring
  • It also carry out overall machine status monitoring and alarm processing
Operation :
  • The fully automatic function (One Touch Printing) runs the machine just by one touch button. Complete press functions are switched on sequentially as per pre defined logic, after attaining the predefined press speed. This function is very useful for waste reduction and getting consistent print quality.
INK WATER BALANCE :
  • Ink water balance is achieved through Siemens S7-400 PLC. There are 3 standard curves which operator can program based on different inputs normally used in the press, like paper quality, Ink quality etc.
  • These three standard curves can be programmed through Touch screen on central console. Before the running of press, operator selects the curve based on his inputs.
  • At different machine speeds at all stations the Ink / water values are fed as preselected curve.
  • These can be modified either from the local station MMI or from the central console Touch Screen.
  • These changes are permanent for that particular station, however the changes can be reset by re-selecting the curve and will be repeated in future every time. These values are stored in permanent non volatile memory.
