Definitions

  • the invention relates to a method and a device for operating a Temperature control device in the inking unit or dampening unit of an offset printing machine.
  • Offset rotary printing machines for wet and dry offset printing are configured in the configuration of sheet and web printing machines.
  • inking units are provided for the application of printing ink.
  • these inking units are provided with a so-called inking unit temperature control.
  • the inking unit temperature control allows the printing ink processed in the inking unit to be heated or cooled as required during the printing process.
  • Temperature control devices for coating circulation systems or coating unit temperature control in coating devices of finishing machines or for the so-called inline coating in connection with offset and flexographic printing machines are also known.
  • the printing machines can be designed in the form of sheet-fed or web-fed printing machines. Temperature control devices have also become known for dampening units on offset printing machines.
  • the temperature control devices are often based on the heat exchanger principle executed. It is preferably through the interior of one of the rollers Inking unit or the coating device a so-called Temperature control medium.
  • a liquid medium is used as the temperature control medium used in an open or closed temperature control circuit.
  • the Temperature control medium can be used for heating or cooling or for heating and be used cool.
  • the temperature control medium is via a cooling unit cooled, for example by means of a heat exchanger or via a Heated element or a heat exchanger.
  • the temperature control and Temperature sensors in the respective printing press or in the Coating is done by adjusting the temperature of the medium or the amount of flow.
  • the temperature control medium consists of a mixture of water and additives to protect the temperature control system in the printing press.
  • the additives serve especially the rust protection. But there are also other types of additives used.
  • the temperature control medium is usually replaced by the Specification of fixed change intervals, i.e. depending on the operating time, replaced.
  • the object of the invention is therefore a device and a method create damage in printing machines with temperature control devices escaping tempering medium reliably prevented.
  • the machine side and / or the unit side Detector or sensor for example a pH value probe and / or a Conductivity probe used depending on the temperature control medium used.
  • the detector or sensor detects the composition of the Tempering medium and takes into account its content components. This affects all substances in the form of protective agents, e.g. Anticorrosive, and also water as part of their respective certain mixing ratios.
  • the sensor continuously or cyclically measures the actual value in the temperature control medium and compares the required setpoint entered via a controller.
  • the setpoint can be saved in the machine control and can be from Manufacturer's side.
  • the setpoint can also be operational specified and entered and saved by the operating personnel, e.g. depending on the local water quality. If the value falls below the setpoint a corresponding error message.
  • the required control can e.g. B. in Machine control center or installed in the temperature control unit.
  • a The error message can also be displayed acoustically or optically. At the same time the value is logged or via data exchange to the Service center or passed on to the machine manufacturer.
  • the temperature control medium can then be replaced during the next cyclical maintenance or refreshed by adding protective agent.
  • the temperature control system can also be checked for leaks or fill level via a pressure sensor, for example a pressure switch, and the temperature control system can thus be monitored for leaks in the temperature control medium circuit. In this way, above all, an uncontrolled escape of temperature control medium within the printing press is recognized. In this way, the quality of the temperature control medium, particularly with regard to the quality of protection against rust, bacteria, lime, etc., can be actively monitored.
  • the temperature control medium becomes active with regard to the still existing Corrosion protection effect and accumulated operational pollution supervised. Fixed change intervals are not ecologically sensible, because not the actual condition of use of the temperature control medium is recorded.
  • the advantage of the invention is that maintenance is tailored to the needs Remote diagnosis or data transfer is possible.
  • the state of the Temperature control systems can be monitored at any time by display on the control center become. Documentation of the actual condition of the temperature control agent, also in With regard to the required maintenance of the printing press, the analysis of Damage cases and assessment of warranty claims can be used. Preventive maintenance is required to maintain the machine condition possible.
  • Manual control work is no longer necessary.
  • the refreshment of the protective agent or one or more of the necessary additives can also be automated.
  • the output of warning messages in the event of a deviation from the limit values to be observed for the composition of the temperature control medium helps to avoid or significantly reduce consequential damage. This also includes simpler cases such as a machine lock, which can only be unlocked by service.
  • the availability of the printing press is increased because reliable system monitoring was created in the manner described.
