Definitions

  • the invention relates to a printing machine lubrication system as such serves the supply and the return of lubricating oil and possibly grease to various lubrication points within a printing press. Furthermore, the invention also relates to a lubricant supply method which serves as such to ensure adequate system lubrication.
  • the aforementioned lubrication points of a printing machine lubrication system are, in particular, sliding and rolling bearing points, gear and chain drives, as well as joint, guide and control cam devices. Some of these lubrication points can only be hermetically sealed to a certain extent so that parts of the lubricating oil can escape during the operation of the printing press or can be contaminated by media to be penetrated, in particular dusts, paints and aqueous media.
  • the invention has for its object to provide solutions by which a safe and low-wear operation of a rotary printing machine can be ensured in an advantageous manner from a business and ecological point of view.

  • the sensor-determined lubricant wear condition can be combined with further information, in particular machine operating information be linked to accurately estimate the lubricity and the potential residual life of the lubricant.
  • the sensor device is designed such that by these mechanical properties such. the viscosity and density of the lubricant are recorded.
  • the sensor device can furthermore be designed in such a way that it also detects electrical properties (dielectricity, permittivity) of the lubricant.

  • reactive changes in the lubricant e.g., sulfation, nitration, oxidation
  • degradation of additives e.g., sulfation, nitration, oxidation
  • filling with unsuitable lubricants, pH, and water content can be detected.
  • Other sensor designs allow conclusions to be drawn about the acidification of the lubricant or, via reversible exchanges on surfaces and builders (for example zeolites), statements about changes in ingredients or the water content of the lubricant.
  • the temperature of bearings and the lubricant is optionally detected at different measuring points, respectively. If the temperature is exceeded, additional cooling systems can be activated.
  • the sensor device can have a plurality of sensors for detecting different material properties. These sensors can be combined to form a sensor module, or be mounted locally distributed in each case at those points of the printing press that allow a particularly advantageous collection of the measurement signal and function of the sensors.

On the basis of the concept according to the invention, it becomes possible to maximize the service life of the lubricant used and thereby achieve considerable savings. Where appropriate, limits on machine performance (e.g., sheet capacity (B / h), or allowable maximum speed) for avoidance of damage shall be limited as a precaution based on oil analysis.
  • the oil condition sensors provided for the lubricant management according to the invention can be arranged in particular in the oil circuit, for example in the oil sump or in the pipe system.
