Abstract
A display system for a rotary printing press for displaying the inking profile on an LED matrix. The profile indication is provided by means of a time shared display with control circuit which scans the positions of all the ink control members, all having position sensors, and sequentially accesses an analog-to-digital converter with decoded outputs which are converted to a number of LED columns, each represented by a continuously lighted LED the coarse position of the ink control member. A fine position indication may be provided by simultaneously showing a fine indication by means of a flash LED in the corresponding column. A still finer indication may be provided by means of a second flashing LED in the corresponding column.
Claims18
Display system for indicating, at a central remote-control location, settings of ink feed for a printing press having a plurality of M ink zones, each ink zone having an adjustable ink zone control member coupled to an ink zone sensor for producing a sensor signal representing a setting value for said settings;
- the display system comprising a plurality of light indicators arranged as a matrix consisting of a plurality of N rows and a plurality of M columns, each column consisting of N consecutively numbered light indicators ranging from numbers 1 to N, wherein N and M represent positive integer numbers, each of said indicators disposed at a respective crosspoint between a row and a column;
- said plurality of columns corresponding to and being equal to the plurality of ink zones and the plurality of rows corresponding to and being equal to the plurality of settings;
- means for producing a coarse setting value signal and a fine setting value signal from said sensor signal for each respective ink zone, means for lighting one light indicator in each column to indicate by its number a respective one of N coarse setting values, and means for simultaneously contrastingly lighting in the same column another light indicator to indicate by its number a respective one of N fine setting values of said control member.
Method for displaying adjustment values for remote-controlled control members for adjusting at least one of a plurality of zones of ink and a plurality of zones of dampening fluid supply from a remote-control location of a rotary printing machine, having an electrical position signal returned from each control member, representing a position value for said control member;
- a plurality of consecutively numbered light-emitting diodes arranged as columns, each column representing a respective zone for receiving a respective position signal;
- each light-emitting diode within each column representing a respective position value, the method comprising the steps of:
- dividing said position signal into a coarse and a fine position signal;
- simultaneously displaying said coarse and said fine position signal for each control member on the respective column of light-emitting diodes as a coarse display and a fine display, wherein said one light-emitting diode within one column serves to display the coarse position value, and another light-emitting diode serves to display the fine position value;
- and a still finer position value is displayed by the light-emitting diode immediately above the diode displaying the coarse value and a not displayed value represented by the next higher light-emitting diode.
Display system for indicating, at a central remote control location, settings of dampening fluid feed for a printing press having a plurality of M dampening fluid zones, each dampening fluid zone having an adjustable dampening fluid zone control member coupled to a dampening fluid zone sensor for producing a sensor signal representing a setting value for said settings;
- the display system comprising a plurality of light indicators arranged as a matrix consisting of a plurality of N rows and a plurality of M columns each column consisting of sequentially numbered light indicators ranging from numbers 1 to N, wherein N and M represent positive integer numbers, each of said indicators disposed at a respective crosspoint between a row and a column;
- said plurality of columns corresponding to and being equal to the plurality of dampening fluid zones and the plurality of rows corresponding to and being equal to the plurality of settings;
- means for producing a coarse setting value signal and a fine setting value signal from said sensor signal for each respective dampening fluid zone, means for lighting one light indicator in each column to indicate by its number a respective coarse setting value, and means for simultaneously contrastingly lighting, in a manner contrasting with a lighting of said one indicator, in the same column another light indicator to indicate a respective fine setting value of said dampening fluid zone control member.
