Definitions

  • the invention relates to methods for qualitative Evaluation of processed material according to the Preamble of claim 1.
  • DE-OS 23 38 849 describes a method for Finding defects in rolled steel surfaces. there those errors are identified that a certain Show periodicity.
  • DE 41 29 126 A1 discloses a method for Detection of defects in a textile web. The number of consecutive errors added. If a faultless product occurs the counter reading is reset to zero.
  • the invention has for its object a method for the qualitative assessment of processed material to accomplish.
  • a processing machine for example a rotary printing machine, is provided with a device for the qualitative assessment of processed material.
  • This material can be printed sheets or webs, for example.
  • sheets of paper are printed using the steel engraving process and then assessed qualitatively inline.
  • the rotary printing press can be, for example, a steel engraving printing press known from EP 04 06 157 B1.
  • picture elements of a sheet to be checked are compared with stored picture elements of so-called "master" sheets. If one or more measured values lie outside a predetermined tolerance of the corresponding measured values of the "master” sheets, an error is detected. This error can now be indicated optically or acoustically by means of a first warning signal.
  • the corresponding sheet with an error can also be marked or sorted out.
  • a counter is fed a signal for the defective sheet, whereby the counter reading of a counting unit, e.g. B. is increased by one. If one or more defective sheets follow directly on the defective sheet, the counter reading of the counter is increased by one for each defective sheet. The counter only adds the counter reading by one counter unit, e.g. B. one up. If an error-free sheet is detected after a defective sheet, a signal for the error-free sheet is fed to the counter. B. one is reduced. Now follow more error-free
  • the counter reading is reduced by one for each error-free sheet. If the counter reading has reached a lower limit, for example the value 0, no further downward counting takes place.
  • the counter reading is thus changed step by step according to the number of inspected, faulty and error-free sheets. This procedure takes place within a range of the counter reading from a lower limit, e.g. B. zero, up to a definable (selectable), upper limit of the counter reading. If this limit value is reached, a second warning signal is triggered and, for example, fed to the machine control. This signal can, for example, cause the speed of the rotary printing press to be reduced or the rotary printing press to be switched off.
  • This procedure is based on the total number of inspecting sheet applicable.
  • the sheets to be inspected are often processed in machines in which cyclical errors can occur. This is the case, for example, when the sheets to be inspected are printed using a rotary printing press known from EP 04 06 157 B1.
  • This rotary printing press has a plate cylinder which is provided with three printing plates, each having an identical printing form. The non-printing areas of these printing plates are cleaned by a common wiper device after inking.
  • This wiping device consists, among other things, of a wiping cylinder operated under pressure. If, for example, one of the three pressure plates is damaged or is partially a little lower, the wiper device does not completely clean this area. Therefore, every third sheet of all sheets produced would have a toning area. Toning areas can also only occur for a limited time, for example by slugs which are removed by the wiping device.
  • each printing plate is assigned its own counter. This counter is synchronized with the printing press and the inspection device in such a way that a signal of an error-free or defective sheet printed on a specific printing plate is fed to the counter assigned to this printing plate. Each counter assigned to a printing plate is therefore only supplied with signals from the sheets printed and inspected by means of this associated printing plate.
  • This particular counter can work according to the following simple principle: If a faulty sheet is detected, a signal is fed to the respective counter, whereby the counter reading is increased by one counting unit, e.g. B. one is increased. This is done for successive sheets up to a preselectable limit. However, by detecting a faultless sheet, the counter reading is reset to zero and only when the faulty sheet occurs again does the counting start. If this limit value is reached, a second warning signal is issued, which is forwarded, for example, to the machine control for triggering further processes.
  • one counting unit e.g. B. one is increased. This is done for successive sheets up to a preselectable limit.
  • the counter reading is reset to zero and only when the faulty sheet occurs again does the counting start. If this limit value is reached, a second warning signal is issued, which is forwarded, for example, to the machine control for triggering further processes.
  • the method described at the outset is also used for counting these cyclically occurring errors. Accordingly, the counting up and down is carried out step by step according to the number of faulty and faultless sheets.
  • This counting of cyclical errors is not just that described example of plate cylinders with several Printing plates limited, taking cyclical errors successive sheets or reports of the web can be detected. There are also other use cases possible. Relevant possible sources of error are that generate a cyclical error, at least one own counter assigned.
  • Step size not equal to one it is also possible to count in other counter units or step sizes (i.e. Step size not equal to one) and with other limit values perform.
