Definitions

  • the invention relates to a method and an arrangement for Control of a printing press according to the preamble of Claim 1 or of claim 13.
  • the press to be controlled has appropriate control means for adjustment different operating states, especially different ones Print speeds.
  • Such operating conditions can e.g. Creep speed, tap forward, tap backward, moving to certain angular positions (for the purpose of Printing plate change) or the like - depending on the type of controlling printing machine - be. It is important that depending on Different types of fabric to be printed Print speeds are adjustable since not everyone Printed with the same high printing speed can be. This can be the case with very thin paper, for example more easily to speed-related disturbances, e.g. in the Sheet run, come as with thicker and firmer paper or thin cardboard.
  • the object of the invention is a method and an arrangement for controlling a printing press of the type mentioned above, which the Avoid mentioned disadvantages and especially the automatic Determination of a given or by the user selectable criteria allow optimal printing speed.
  • This task is solved by a control method a printing press, in which an evaluation and Monitoring unit between two definable times the operational and fault-related downtimes of Printing press as well as at least one for the type of one between the predeterminable times by means of the printing press printed material characteristic parameters are detected, the recorded times and parameters according to given or selectable first criteria in relation to each other set and at least partially saved and from the data thus obtained from the evaluation and Monitoring unit depending on the type of each to be printed on a given or selectable second criteria optimally adapted printing speed is determined.
  • the method according to the invention leads to relief of the printer, because it - quasi as a self-learning system - automatically evaluates information obtained during operation and optimally adapted to the wishes of the user Print speeds determined. This will result in incorrect operation avoided and the availability of each Printing press increased. It can also be simple and used inexpensively with existing printing machines become.
  • Procedure is in addition to the fault-related Downtimes characterizing the reason for the fault Parameters recorded.
  • the method can the data obtained depending on the type of one an average printing speed and a previously highest printing speed determined and displayed. They are preferred from the average printing speed and the previous one highest printing speed three speed ranges determined and displayed to the operator.
  • controllable variables by the operator e.g. Pressure, tension, speed or the like
  • the three areas mentioned e.g.
  • the evaluation and monitoring unit obtained data according to predetermined or selectable third Criteria one for a certain type of one to be printed
  • the maximum permissible printing speed is determined and as a preferably not exceedable target speed the tax resources. That way it is possible, incorrect operation when setting the printing speed completely excluded, since the operator no speed, the determined target speed exceeds, can choose.
  • the evaluation and monitoring unit At the two definable times between which the operational and fault-related downtimes of Printing machine and at least one for the type of printed substance characteristic parameters are detected by the evaluation and monitoring unit, it is preferably the start and end of a print job, being under the term "print job" certain order to be executed with the machine understood where the same type of fabric with one and the same pressure should be applied.
  • the process can be further automated in that the operating times and / or the malfunction-related downtimes the printing machine from the evaluation and monitoring unit be recorded automatically. It is the same possible that the evaluation and monitoring unit at least one for the kind of one between the prescribable Points in time printed on the printing machine characteristic parameters automatically recorded. To this Way is avoided that e.g. an operator this Data must enter whatever the risk of incorrect entries conditionally.
  • the stated task is based on an arrangement for Control of a printing press in the preamble of Claim 13 mentioned type further solved in that the Evaluation and monitoring unit for recording the Operating and fault-related downtimes of Printing machine between two predetermined times, for Capture at least one for the type of one between the predeterminable times printed by means of the printing press Material characteristic parameter, for evaluation and at least partial storage of the recorded times and parameters according to predefined or selectable first criteria and to determine a depending on Art of the respective fabric to be printed on at predetermined or selectable second criteria optimally adapted printing speed is formed from the data obtained.
  • the evaluation and monitoring unit for detecting a Characterizing due to a malfunction-related downtime Parameters trained. This enables one particularly precise evaluation of the evaluation and Monitoring unit recorded data and thus a special one effective control of the machine.
  • the evaluation and monitoring unit has an arrangement about means of differentiating those based on a disorder one for the type of fabric to be printed on downtimes based on high printing speed of other downtimes. This allows interference based on a for the respective type of to be printed To determine the material at high printing speed and the adjust the optimal printing speed accordingly.
  • Prefers is the display device for displaying several, formed in particular by three speed ranges. The display device can expediently at the same time the current printing speed of the printing press Show.
  • a further automation and thus simplification of the Control can be achieved with an arrangement in which the evaluation and monitoring unit directly with the Means for controlling the printing press is coupled. It is both possible, only operating and control signals from the means for controlling the printing press to Transfer evaluation and monitoring unit so that no special sensors to detect the operator set operating conditions are necessary as well Control signals in particular permissible maximum speeds from the evaluation and monitoring unit to the means to control the printing press so that the Evaluation and monitoring unit in the event of incorrect operation actively intervenes in the control of the printing press.
  • Another automation and simplification of operation can be achieved in that a sensor coupled to the evaluation and monitoring unit Detection of at least one for the type of substrate characteristic parameter is provided. This automatic Recording the type of substrate makes a corresponding one No need for operator input.
  • Terminal 12 and control computer 14 form the control means for setting various operating states, in particular different printing speeds.
  • the of the Operator commands entered at Terminal 12 are via a line 16 for signal transmission to the control computer 14 forwarded the corresponding control commands Converts control signals and via a line 18 for signal transmission to the printing press 10.
  • the printing press 10 is monitored by various monitoring sensors is monitored, especially in this embodiment a sensor 20 for monitoring the actual Print speed, a sensor 22 for detecting the Type of substrate and a sensor 24 for detection printing speed-related disturbances and resulting Downtimes are planned.
  • a Evaluation and monitoring unit 32 forwarded.
  • signal transmission means 34 between the control computer 14 and the evaluation and Monitoring unit 32 is provided, via which information e.g. via that from the operator to the terminal 12 predetermined operating parameters, from the control computer 14 forwarded to the evaluation and monitoring unit 32 become.
  • the evaluation and monitoring unit 32 now evaluates the recorded information and in particular determines one optimally adapted to specified or selectable criteria Print speed, which is via signal transmission means 36 forwarded to a display device 38 and displayed there become. It should be emphasized at this point that the in The schematic sketch shows the spatial separation from the control computer 14 and evaluation and monitoring unit 32 pure is to be understood functionally. In fact, it can be useful be the evaluation and monitoring unit 32 in the control computer 14 to integrate.
  • the terminal 12 and the evaluation and monitoring unit 32 can optionally signal transmission means 42 between the terminal 12 and the evaluation and monitoring unit 32 which enable the operator to directly with the evaluation and monitoring unit 32 to communicate and in particular to provide her with certain data. That's the way it is e.g. possible that the operator in addition or instead of the sensor 22 detecting the type of printing material about the substrate type of the evaluation and monitoring unit 32 transmitted or corresponding information about this type of fabric, especially the one to be chosen Print speed queries, which is then by means of Display device 38 are displayed. It is also on in this way possible that the operator determined by the evaluation and monitoring unit 32 stored Deletes or corrects information, e.g. if a disturbance erroneously than on too high a printing speed based on the evaluation and monitoring unit 32 and the permissible for a certain type of substance Maximum printing speed erroneously lowered and a too low optimal printing speed is determined has been.
  • an arrangement according to the invention are also signal transmission means 40 between the Evaluation and monitoring unit 32 and the control computer 14 provided, via which higher priority control signals from the evaluation and monitoring unit 32 to the control computer 14 can be specified.
  • "Priority higher” are from control signals generated by the evaluation and monitoring unit, which takes precedence over that of an operator of the terminal 12 have generated control signals. Poses So an operator mistakenly one for a particular one Operating status or a certain type of substance too high printing speed the evaluation and monitoring unit intervenes corrective here and lowers automatically the set printing speed.
  • FIG. 2 shows a possible form of the display of the evaluation and monitoring unit determined information shown.
  • the one designated in its entirety with 38 Display device is not necessary as a conventional one Display instrument, e.g. in the form of a round instrument such as. to understand a tachometer; it can happen rather also a display device in the form of a Screen (possibly as an integral part of the terminal 12 act according to FIG. 1), which is why also in FIGS. 2 and 3 the known physical characteristics of the Display device 38 and 38 'have been omitted and the display on the information display of interest to the user has been restricted.
  • a "Pointer” 50 which for example is only virtual, i.e. in shape of pixels existing on a screen shows the actual current printing speed.
  • the areas 44, 46, 48 - in reality preferably by colors, especially differentiate between green, yellow and red - symbolize different speed ranges, namely a non-critical area 44, a critical area 46 and a supercritical area 48, each through an increasing likelihood of speed-related Disturbances, e.g. Characterized disturbances in the arcing are.
  • the operator thus receives an easily readable and above all easy to understand information about in which speed range the printing press is driven and should be driven.
  • FIG. 3 Another type of display is shown in FIG. 3, in the display area is again in three different, through here different hatches, in reality preferably areas 44 'identified by different colors, 46 'and 48' divided.
  • a pointer 50 ' shows the current one actual print speed.
  • a scale graduation 52 ' is provided, on which the Absolute value of the print speed is easy to read. It should be noted at this point that of course also provided with numbers in the display according to FIG. 2 Scale lines can be provided, which allow read the absolute value of the printing speed immediately.
  • the operator passes through the terminal 12 Control commands, which are then processed by the control computer 14 and be converted into corresponding control signals.
  • the operator can do this beforehand or during during operation ask which print speed criteria that can be selected by her or certain, predefined criteria is optimally adapted. This speed can but can also be displayed permanently.
  • print speed criteria e.g. be: minimizing the interference-related, in particular of malfunctions due to high printing speed based downtime, minimization reject production due to excessive printing speed or maximizing print speed.
  • these criteria can be predetermined, preferably however, they can be selected by the operator since the criteria vary depending on the type of substrate could be. So it is e.g.
  • the property of the arrangement is its permanent capacity to "learn" yourself, i.e. the ability to operate automatically implement information obtained from the printing press and to control the machine directly, namely by acting on the control computer, or indirectly, namely by displaying the information to the operator, to provide.
