Definitions

  • the invention relates to a control for a printing press according to the preamble of claim 1.
  • Sheetfed offset presses from widespread type usually have a central control in the form of a PLC or PC board control on. This control is on one with an angle encoder single-speed shaft in connection, so that the angular position values this Angle encoder within the control (a computer) with stored target angular position values compared for switching operations to be triggered accordingly can be.
  • Such central controls have the disadvantage that this according to the equipment of the machine (number of printing units, coating and other inline finishing facilities) must be designed.
  • a control for a printing press is known from DE 195 20 919 A1 which the printing press several units such as feeder, printing units, Painting equipment, boom and the like.
  • the individual units are assigned stations designed as computers, which via a particular connected to each other on a message-based protocol are.
  • An absolute or incremental angle encoder is arranged on one of the units (single-revolving shaft), whose angular position values over a separate bus system (angular bus) to the individual stations.
  • angular bus angular bus
  • On detected in a unit via sensors arranged in the respective station Event is communicated to the other units via the first bus system, whereupon the functions to be triggered according to the determined event the station computers in the other units depending on the angular position signals triggered on the angle bus. This is done in the respective Station a comparison of the angular position signals present on the angular bus (Actual angular position) with target angular position values stored in the respective station.
  • the angle bus is for transmission the angular position values as one of the incremental or absolute angular position values transmitting bus system.
  • the angle bus Becomes an absolute angle encoder and a parallel bus system for transferring the absolute angular position values used, such a training expensive because of the associated Wiring costs the bus system considerably.
  • the use of a fast serial bus system is cost-intensive Transmission of the absolute angular position signals of an absolute angle encoder With a high resolution rate of the absolute angle encoder, however, do not have to only the bus system but also the interfaces in individual units Reading the angular position values should be designed to be correspondingly powerful.
  • an incremental encoder as an angle encoder has the disadvantage that that an absolute angular position information in the form of a zero pulse only at Run of the machine can be obtained. Accordingly, after the start of the Machine does not depend on the angular position until the first receipt of a zero pulse switching operations to be triggered. On the other hand, it is advantageous the usability of an incremental bus for transmitting the signals of the incremental encoder because of the small number of lines and the lower Isolation effort.
  • the object of the present invention is therefore a control according to the Develop the preamble of claim 1 such that, while avoiding the Disadvantages mentioned above by reducing the construction effort an inexpensive design of a bus system transmitting angular position values is obtained.
  • an absolute angle encoder in one of the units of the printing press an absolute angle encoder is provided, the absolute angle position signals converted into incremental signals by a downstream evaluation electronics are, these incremental signals during machine operation over the as Incremental bus trained angle bus to the individual stations (computers) of the Units are supplied.
  • the evaluation electronics of the absolute angle encoder stands additionally with which the individual stations for the transmission of Switching commands connecting bus system in connection, so that at Machine standstill absolute angular position values at the other stations are transferable. This ensures that even when the machine is at a standstill each of the stations (computers) has information about the current one Angular position the machine is currently.
  • angular position Switching functions can be triggered. For example, by a sensor in the unit representing the first printing unit of the machine a missing sheet of the system, a corresponding command "Missing sheet system" is via the one based in particular on a message-oriented protocol Bus system forwarded to the other stations.
  • a sensor in the unit representing the first printing unit of the machine a missing sheet of the system
  • a corresponding command "Missing sheet system" is via the one based in particular on a message-oriented protocol Bus system forwarded to the other stations.
  • each of the individual Units (individual printing units) is then the according to the sheet run Blanket cylinder at the intended angular position of the impression cylinder and then turned off from the blanket cylinder.
  • each Station for example, arranged in the evaluation group and an offset angle value containing memory, the content of which is permanent from the initial value of the counter of the evaluation group providing the current actual angle value is subtracted.
  • This offset angle value is for the individual Stations of the units chosen in such a way that to be executed on a specific command Switching operations in each station with a uniform target angular position value can be triggered.
  • a sheet-fed printing machine that can be converted from perfecting to perfecting can, in addition to a first angle encoder (before the turn), a second one Angle encoder (after the turn) should be provided.
  • the signals from the angle encoder, attached to the part to be rotated when moving the machine are then used for format-dependent positioning.
  • the machine is running can use the signals from the two angle sensors for monitoring the coupling device the turn can be evaluated in a suitable manner.
  • a printing machine not shown, has a plurality of units 1.1, 1.2, 1.3 in the form of an investor, one or more printing units, painting equipment as well as a boom.
  • the individual units are 1.1- 1.3 each assigned to stations 2.1 - 2.3 comprising at least one computer, by which the switching operations to be carried out in the respective unit 1.1 - 1.3 as well as monitoring the sheet travel (sensors - not shown), etc. become.
  • An angular encoder is located on a single-speed shaft of the printing press, not shown 4 in the form of an absolute angle sensor, to which an electronic evaluation unit 5 is connected downstream. According to the invention it can be provided that the evaluation electronics 5 integrated in one of the stations 2.1 - 2.3 of the units 1.1 - 1.3 is.
