  • controller here z. B. the setpoint controller and the protocol controller
  • the protocol controller and the setpoint controller in a common processor are processed as command sequences.
  • setpoint signals are all Understand information directed by the processor to a specific color zone are to control the adjustment processes of a respective ink zone squeegee. These setpoint signals or color zone control signals are thus sent to the respective protocol controller Color zone transmitted as input.
  • each color zone in accordance with the present invention includes a protocol controller and is directly connected to the local area network (LAN), enables the present Invention the construction of a simple and reliable control device of color zones.
  • the number of cables can be reduced by the invention become.
  • a malfunction of a controller only leads to an incorrect setting of one single color zone and not mis-setting a large number of color zones.
  • Each color zone can also have an I / O driver to receive input from the Setpoint controller and include a motor controlled by the I / O driver.
  • each ink zone has a squeegee setting device driven by the motor comprises, by means of which to adjust the thickness of a Ink roller fed ink layer a squeegee is adjustable.
  • each color zone can also be connected to the motor connected potentiometer that provide feedback regarding the position of the Squeegee passes to the setpoint controller.
  • the feedback is preferably carried out via a voltage value that is sent to an A / D Converter is transmitted.
  • a can be used to monitor the motor position Counters are used.
  • the A / D converter can then send a digital value to the Output setpoint controller. This can provide this information in the correct protocol form route over the local network (LAN).
  • LAN local network
  • Each color zone may preferably include a housing in which the protocol controller and the setpoint controller, possibly also the I / O driver, the A / D converter as well the motor, the potentiometer and the doctor blade are arranged.
  • the LAN can be used as a commercially available LAN, e.g. B. be designed as a PROFIBUS, and preferably has a protocol for transmitting setpoint information to a certain color zone of the plurality of color zones.
  • B. be designed as a PROFIBUS
  • the protocol can provide information regarding the web, the web side and the Contain color for the specific color zone.
  • the protocol controller detects when a Message is directed to the color zone assigned to it, and filters the setpoint information out.
  • the setpoint can then be sent to the setpoint controller who reads the setpoint query and compares it with the current setting. Out this comparison can (if necessary) determine a necessary actuating movement, and the color zone is set to the desired setpoint using the I / O driver. there can feedback the motor via the potentiometer and the A / D converter be taken into account.
  • a control algorithm of the setpoint controller can ensure that the motor is set within a specified setpoint range.
  • the I / O Driver switches the motor on and off.
  • a change in voltage polarity on Motor changes the motor direction.
  • the feedback from the potentiometer is converted into a digital value by the A / D converter, so that the setpoint controller can compare the current position of the motor with the setpoint. Once the the specified setpoint range is reached, the I / O driver can switch off the motor.
  • the color zone electronics can be operated by low voltage, e.g. B. with 12 volts Direct current.
  • a protocol controller for receiving input from a local network, a setpoint controller to receive input from the protocol controller, one with the Setpoint controller connected I / O driver and one controlled by the I / O driver Motor is provided that the protocol controller, the setpoint controller, the I / O Driver and the motor are arranged in the housing.
  • the modular arrangement of the color zones enables easy replacement and one easy connection to the LAN.
  • the ink zones each having a setpoint controller which receive setpoint signals from a processor is provided that a desired setpoint for a color zone is determined, that the setpoint is over a local network transmitted to the color zone and to the color zone by means of a protocol controller is received and that the color zone depending on the target value is set.
  • the setpoint is sent in a LAN protocol by a protocol controller is received at the color zone.
  • Fig. 1 shows a programmable unit (Programmable Logic Controller, PLC) or a computer (PC) or processor 12, which is used to adjust the ink supply for a variety of ink zones in a printing press by an operator e.g. B. one through one serial connection or interface 9 from one connected to the PLC 12 Control console controller 10 is controlled.
  • the ink supply can alternatively also by an algorithm depending on the print quality of the output products to be controlled.
  • a processor that may be part of the PLC 12 receives data relating to the from the PLC 12 desired ink supply and calculates target values for the Ink zones of the printing machine.
  • the target values for the different color zones will be then by a communication driver 14 in the form of a communication protocol forwarded over a local area network (LAN) 2.
  • the communication protocol can vary depending on the type of LAN used; any color zone can for example, be represented as a certain number with which a setpoint for the color zone in question is sent.
  • the protocol can also be designed in such a way that a color zone is identified by first the web, then the web side, the Color and finally the color zone for the color in question is determined.
  • a color zone group comprising the color zones 50 and 60 62 may be assigned. This information can be used to identify the color zone together with the target value for this color zone.

  • Each of the color zones is advantageously designed as the color zone 20 shown in detail.
  • the LAN 2 is with a protocol controller 22 of the color zone 20 connected.
  • the protocol controller 22 receives signals from the LAN and filters them when it receives a signal for the color zone 20 Setpoint information and transmits it as digital data to a setpoint controller 24, which switches an engine 28 on and off via an I / O driver 26 controls.
  • the motor 28 moves a squeegee adjuster 30 which, as shown in FIG. 2 is, the distance between a doctor blade 8 and an ink fountain roller 6 controls. To this In this way, the thickness of the ink layer transferred from the ink fountain 4 to the roller 6 to be controlled.
  • the ink fountain roller 6 is a plurality of doctor blades 8 intended.
  • setpoint controller 24 receives input from an A / D Converter 32, via a potentiometer 34 information regarding the current position the doctor blade adjusting device 30 are supplied.
  • the potentiometer 34 sends one analog voltage signal to the A / D converter 32, which converts the signals into a digital value converts, which is then entered into the setpoint controller 24.
  • the desired setpoint for the color zone 20 is set by the setpoint controller 24 set the way described below.
  • the protocol controller 22 The setpoint received is determined by the potentiometer 34 via the A / D converter 32 received current setting compared. Should the position of the squeegee 8 changed the direction of the change in position is first determined, i. H. whether the squeegee adjuster 30 the squeegee 8 towards the ink fountain roller 6 or away from it should move.
