Definitions

  • the invention relates to a blowing and / or suction air supply for a printing press according to the preamble of claim 1.
  • Blown and / or suction air is used on a variety of sheetfed offset presses Positions needed. Blown air is particularly useful for separating in the area of the feeder the top sheet of the feeder stack and for the trouble-free transport of the shed the sheet conveyed to the system.
  • Blown air By means of clocked suction air a top sheet is removed from the stack and over a transport roller fed to the conveyor table.
  • Blown air inside the printing machine is used for lubrication-free Sheet routing between the printing units. After printing one last sheet and, if necessary, inline finishing using coating units or the like. Then the sheets printed on one or both sides (fine and Back pressure) placed on a stack of cantilevers. Also in the area of the boom Accordingly, a variety of blowing and / or Suction air consumers use the to arrive in time with the printing speed Brake the sheet and place it on the delivery pile.
  • Valves are the individual blowing and / or suction air consumers individually adjustable, but this does not affect the power requirement and thus the Operating costs of such a system, since blown air is usually not required blown off via appropriate valves or one with maximum negative pressure provided suction air via appropriate valves with ambient air on the intended pressure is diluted.
  • the relatively high noise level in the operation of such a central air supply device a printing press to be regarded as disadvantageous. This has its cause in particular in that the blowing and / or Suction air consumers generate different noise levels that are addressed Valve devices, however, represent additional sources of noise. Further also ensures the blowing and / or suction air generating device operated at constant power (Pump / blower) for a consistently high noise level.
  • blowing devices which is a streamlined sheet held on a sheet-guiding printing cylinder a printing zone (gap between blanket cylinder and impression cylinder) should come in.
  • the setting of the optimal blowing air strength is particularly critical, because the tightening of stiff substrates, on the one hand requires high blowing air strength, but on the other hand should be avoided, that the excessively adjusted blowing air in the area of the leading edge of the sheet under the Bow (between cylinder surface and bow) is blown, which is a rolling out this air cushion through the pressure gap and thus to uncontrolled movements of the bow end and especially the corner of the bow.
  • DE 34 13 179 A1 is a control and regulating device of a sheet delivery known in the adjustable elements of the boom with remotely adjustable Drives and position indicators are provided.
  • Remotely controllable are described Valves for individually depending on the substrate and subject Ink application and printing speed adjusted setting of suction and / or Blown air consumers such as suction rolls and blow pipes in particular.
  • This Devices can be controlled via the remotely controlled valves Characteristic curves are operated, which can also be modified by setting setpoints are. Thanks to the remotely controllable valves, it is also possible to make the settings to save the suction and / or blown air consumer and to a later Time to recall and bring to the setting. With this previously known Device is constant suction or blowing air from an air generator (maximum) pressure specified.
  • EP 0 503 623 B1 describes a device for regulating the blown air requirement of the Separating nozzles in a sheet feeder of a sheet-fed rotary printing press known, in which a control device is provided, which is dependent the machine speed and characteristics is influenced.
  • a control device In the pipe system There is an adjustable between the blown air consumers and the blown air generator Pressure relief valve arranged, which is set in this way by the control device is that the air pressure in the pipe system always the intended Has value.
  • the above is accordingly blown off the existing air volume of the intended pressure in the pipe system, which means that the delivery rate of the blower is designed accordingly is.
  • a disadvantage of the last-mentioned blown air control device is that it is complex Valve and this valve associated adjustment device is to be provided. This causes corresponding costs especially with high blowing air capacities. Is with this known blown air control device, the pressure of the blown air to a predetermined Value adjustable, but this does not affect the power requirements of the Blower air generator and thus the energy consumption. Furthermore, this facility switchable from non-adjustable blowing air to adjustable suction air and vice versa.
  • the object of the present invention is therefore to provide a blowing and / or suction air supply for a printing machine according to the preamble of claim 1 such to improve, so that avoiding the disadvantages mentioned above an individual adaptability of a blowing and / or suction air supply to one Printing machine is possible and in particular an easy-to-use setting the large number of blowing and / or suction air consumers is guaranteed.

  • each blowing and / or suction air generator of a unit of the printing press has a control by which the delivery capacity of the particular designed as a blower (side channel compressor) Air flow conveyor is adjustable. This ensures that everyone and overall, all blowing and / or suction air generators only consume as much power as well as overall to provide the blowing and / or suction air on the Machine is needed.
  • each Air supply unit a controllable blower, i.e. a compressed air generator has, by whose air the blown air consumers in the assigned Unit of the printing press can be acted upon.

  • the device for providing at least a signal that changes with the pressure in the line as a current draw of the drive motor of the blowing and / or suction air generator Device is trained. This takes advantage of the fact that the current consumption the engine of the blowing and / or suction air generator in a more or less wide range of delivery capacity changes depending on the pressure in the system. It can be provided that the control and regulating device Current consumption of the drive motor of the blower and / or suction air generator via a current sensor takes place, or that the control device regulates the current consumption of the drive motor of the blowing and / or suction air generator in the form one provided by the converter / frequency converter of the drive motor Signal is supplied.

  • Training can, however, be provided that, for example, with a Control and regulating device connected potentiometer or via buttons of a Control panels, in particular via a corresponding control center menu Regulation specified pressure setpoint according to the pressure conditions can be changed. This sets the use of the current pressure value proportional signals delivering pressure transmitter ahead.
  • the current over the pressure value delivered to the pressure transmitter in the line system (blowing or suction operation) depending on the operating status of the machine and the pressure conditions representing signals / data is further processed. That's the way it is in particular possible to use the pressure setpoint to be used as the basis for the control Function of the machine speed (printing speed) according to a predetermined To change the characteristic. So then takes place through the tax and Control device the tracking of the pressure in the line system via a control of the asynchronous motor of the blower at higher printing speeds after a particularly higher pressure value than at low printing speeds. Furthermore, it is also possible to add further machine or printing parameters in the case of the variable and, in particular, characteristic-dependent modification of the target value to consider.
