Definitions

  • the invention relates to a control for a printing press, in particular Sheetfed offset printing machine according to the preamble of claim 1.
  • Sheetfed offset printing presses of the type widely used today generally have so-called central controls, which in particular in the form of a PLC or. PC board control are built. It is also known to control the Functional division of the printing press. So a computer can be provided that permanent the switching states or signals of actuators, control buttons or sensors reads and a second computer in particular the main drive and the on the angle of rotation controls switching operations of the printing press related to moving machine parts.
  • switching functions dependent on the angle of rotation are examples here Print on / print off the switching on and off of ink and dampening rollers, blocking the sheet inlet, switching the feeder and switching certain ones Functions called in the boom. These switching operations are time-critical, i.e. especially the positioning of the colored rubber blanket cylinder on the sheet-bearing Counter pressure cylinders may only follow the cylinders during channel correspondence if the first sheet to be printed is already on the impression cylinder.
  • a disadvantage in such a centrally constructed and implementing a sequential circuit Control is that the program structure in the computer of the control exactly on the Configuration of the machine must be switched off.
  • a sheetfed press with one different number of printing units therefore requires a different number Programming the corresponding control. This is complicated significant, which is a clear trend towards the so-called In-line finishing or further processing exists.
  • In sheetfed offset presses are often one or more after the last printing unit and before the delivery Painting facilities or other coating plants interposed. Since also in these devices must perform switching operations dependent on the angle of rotation position this function is also taken over by the central control.
  • a central control of the type briefly outlined above is known from DE 3 815 534 A1, which has a system for detecting the position of moving machine parts. For this purpose, the signals of a single-rotating shaft of the machine attached incremental encoder evaluated. This system evaluates not only the square-wave signals of the incremental encoder, which are phase-shifted by 90 ° but also the so-called zero impulses, which occur at each full, single-turn machine rotation.
  • a central control with one such a system has the aforementioned disadvantages.
  • a so-called absolute angle encoder can be used. However, this does not change anything Complexity of control that arises when a printing press is customized with a different number of units is equipped.
  • a control for rotary printing presses is known from EP 0 543 281 A1 which is assigned to each system part a computer representing the control and this Computer in the individual system parts for the purpose of signal exchange via a network designated bus system are interconnected.
  • ARCNET is proposed using a coax cable. How in this document, however, individual rotation-dependent switching operations are to be carried out not described.
  • DE 42 14 394 A1 describes a multi-motor drive for a rotary printing press known in which a number of cylinders and at least one folder each have a separate drive.
  • the individual drives of the cylinders and their Drive controllers are grouped into pressure point groups, these pressure point groups are assigned to one of the folders and their position reference get from this folder.
  • the administration of the pressure point groups takes place through a superordinate control system.
  • the angular position values transmitted via the bus systems are used to generate synchronism, for example between two separately driven cylinders, but not triggering at certain angular positions switching operations.
  • the object of the present invention is therefore a controller according to the preamble of claim 1 to expand in such a way that the disadvantages described above can be avoided and a high flexibility with regard to the equipment of the Machine is achievable.
  • Another bus is provided, via which the signals of the angular position of a Angle sensors are transferable, this angle sensor on a single-speed rotating Machine part of the printing press is attached.
  • this angular position values transmitting bus system each individual station receives information about the current present angular value.
  • the individual stations are corresponding to those on the bus transmissible events stored target angular position values so that the individual Stations trigger the intended switching processes in the assigned units can.
  • the Printing machine on a single-speed rotating machine part a so-called Incremental angle encoder is arranged.
  • the bus system provided according to the invention comprises a number of lines over which the individual against each other phase-shifted incremental signals are sent.
  • the invention Bus system also has a further line, via which after each full Machine revolution a so-called zero pulse is sent.
  • the bus system the individual stations in the units the angle values of a rotating on a single-speed Machine component attached angle encoder fed.
  • the machine component of the printing press is in particular the plate cylinder Blanket cylinder, the simply large impression cylinder or for example one to understand the single-drum feed drum.
  • the Bus system in addition to the Bus system as an event-driven, message-oriented communication system, i.e. as a bus system with one message-oriented protocol is formed.
  • the CAN bus is preferred here (Controller - Area - Network) use. It is through such a trained bus possible that a station, which by sensors or other control means certain event detects a message of this event via this CAN bus transmitted and the stations then in the assigned units the intended Trigger angle-dependent switching processes.
  • Target angular position values now solve the respective switching processes in which in the assigned units (e.g. consistent print-Ab in the first printing unit downstream printing units and disengaging the feeder).
  • the station 5 takes over the boom of the Sheet printing unit 5 all relevant for the delivery Switching processes such as, in particular, the one coordinated with the sheet travel, i.e. so too a certain angular position switching means for an automated Stack change or a sample sheet removal.
  • the station 2 'in the first printing unit performing unit 2 is also with sensors for the sheet arrival at the System in connection - only one sheet control 9 is shown here.
  • the individual Stations 1 'to 5' are connected to one another for signal exchange via a bus 6, this bus 6 as a message bus (CAN bus / controller area - network) is trained. Via the bus 6, the individual stations 1 '- 5' are also included a control center computer, not shown, and the main drive of the machine connected so that data for presets u. Like. To the individual computers and Running commands can be forwarded to the drive.
  • the station 2 'of the unit 2 which represents the first printing unit Sheetfed offset press has one attached to a single-speed shaft Angle encoder 7, which is connected on the one hand directly to the station 2 'and on the other about a further explained below and the angular values of this encoder transferred bus 8 to the other stations 1 ', 3', 4 'and 5' is connected.
  • Each of the Stations 1 'to 5' have corresponding devices designed as an interface, by means of which the signals of the angle encoder 7 are continuously detected and read can.
  • a missing sheet understood a lack of a sheet on the system with the machine running. At a It is therefore absolutely necessary for such a missing sheet that the Blanket cylinders can be turned off by the impression cylinders to color the To prevent impression cylinders. Also the cylinder in the The coating unit (unit 4) must be switched off. Have the shutdowns described to be carried out in a logical manner in accordance with the sheet travel, so that they are still correctly in the Machine incoming sheets can be printed out.
  • the station 2 'of the unit 2 representing the first printing unit is located with a Bow control 9 in connection and evaluates the signal of this bow control 9 permanently out. At a certain point in time, station 2 'prevents the sheet from missing, so a missed sheet was found.
  • a memory of the station 2 'designed as a computer are stored angle values which correspond to those values for which the parking the printing unit cylinder has to take place in unit 2.
  • the station 2 'now causes the locking of the system, the pre-gripper, in accordance with the predetermined angle values and then the parking of the blanket cylinder from the impression cylinder and that Parking opposite the plate cylinder in the first printing unit.
  • stations 1 ', 3', 4 'and 5' Also stored are angular values at which 1, 3, 4, 5 in these units switching measures to be carried out.
  • station 1 on the bus 6 has received the "Missing sheet in the first printing unit” event, is transmitted by station 1 ' the investor switched off.
  • station 1 ' After a number of Revolutions is also caused by the message "Missing sheet in the first printing unit” received stations 3 ', 4', 5 'for the intended, stored angular values Pressure shutdown initiated.
  • stations 1 'to 5' evaluate both the angle signals within one revolution as well as the total number of revolutions.
  • the other switching operations in the individual units 1 to 5 are also initiated. It is essential that the individual stations 1 'to 5' permanently Read in the angle setting values of the angle transmitter 7 and one of them via the message bus Event according to message from one of the stations 1 'to 5' to the other stations 1 'to 5' is sent and each of the stations 1 'to 5' the required Switching operations in the associated units 1 to 5 by comparing the detected executes current with the correspondingly saved angle values independently.
  • a Another advantage of the permanent detection and evaluation of the angular position signals in the individual stations 1 'to 5' is also that the individual stations 1 'to 5' also regardless of the presence or receipt of a message / event can perform angle-dependent switching functions in the associated units.
  • a decentralized control constructed in this way according to the invention is very advantageous for so-called time-critical functions.
  • Fig. 2 shows an embodiment of the invention, here the angle encoder 7 as a so-called incremental encoder is formed.
  • the angle encoder 7 first printing unit of the unit 2 representing sheetfed offset printing press appropriate.
  • the station 2 'of the unit 2 each Incremental signals of tracks A and B and a phase-shifted from one another by 90 ° so-called zero pulse on the N track.
