Definitions

  • the invention relates to a device for controlling a printing press, in particular a sheetfed offset printing machine, in which a control unit depending on an actual position of an actuator Control signal to achieve a predetermined position.
  • a device for positioning adjustable actuators Printing machine is known from DE 197 17 297 A1.
  • At this facility are as sheet brakes, suction rings or sheet guiding devices trained actuators movable on a common support arranged, each actuator having a drive motor which with is connected to a controller.
  • the disadvantage here is that the actuator is no longer effective in the printing process by switching off the drive motor. This leads to an increased error rate when processing the sheets to be printed, since, for example, incorrect sheets are fed into the printing units or the sheets are incorrectly deposited in the delivery, or the sheets are not properly printed or are damaged in the printing process. It can even go so far that the printing process must be completely interrupted by the status of the entire system in order to check or replace a defective actuator.
  • a ink metering element for a printing press is known from US Pat. No. 5,287,808, which is remotely adjustable via an actuator. To determine a Zero position, in which the tip of the dosing element is in contact with an inking roller, it has an acoustic sensor whose signals are controlled by a controller be evaluated.
  • the invention is therefore based on the object of a device for control to specify a printing press in which, despite the failure of one or more Actuators the printing process can be continued.
  • the object is achieved in that after detection an error of the actuator by the control unit setting the actual position of the actuator by manual positioning takes place, the manually set position for further printing of the actuator of the position specified by the control unit is equated.
  • the advantage of the invention is that the actuator does not fail brings the entire printing press to a standstill. Especially at Automated processes can fail one or more Actuators are bridged, so that from the point of view of the control unit none There is an error. This facility works regardless of the structure of the Actuator.
  • control unit is equipped with one that displays the error Display device connected, when actuating an operating element an operating unit, the control unit can be put into an emergency operation routine and the display device receives a request after setting the emergency running routine for positioning the actuator.
  • Control unit sets thus the actual value of the position of the actuator with the other processes whose setpoint is the same, no further control of the actuator is required.
  • control unit is via a central control device the printing press with the display device for displaying the current one Operating state of the printing press and the control unit for entering Commands and commands connected. Display device and control unit can thus be used for all stations of the printing press.
  • the printing press advantageously consists of several Functional units, each functional unit one, the functional sequences is assigned to this functional unit controlling control unit, which with the central control unit of the printing press via a data bus data change. All of these control units are managed by the central Control device monitors which, if necessary, an emergency program for can initiate every single control unit.
  • a sheetfed offset printing press has various, not shown Functional units.
  • This includes a feeder for receiving the sheet and its feed to the first printing unit, several independent Printing units and an extension arm, in which the printed sheets are recorded and be filed in an orderly manner.
  • each of these Functional units controlled by a functional unit control device, which independently switch functions in the assigned functional unit performs.
  • Bow guide elements are arranged in each functional unit, which must be set according to the current process conditions. At the Example of the boom 1 functional unit shown in FIG. 1 is intended to do this are explained.
  • the printed sheet 2 coming from the printing units of the printing press is gripped on the boom 1 by grippers 3 and guided by suction wheels 4. After reaching the arch stop 5, the arch 2 is on a Sheet stack 6 filed. Above that falling onto the sheet stack 6 Arches 2 are a variety of fans, of which for the sake of clarity only three fans 71, 72, 73 are shown, distributed so that approximately the entire surface of the sheet 2 sliding on the sheet stack 6 through the Fan can be influenced specifically. In the example shown in Figure 1 only the fan 71 generates upper air, whereby the storage of the sheet 2 is targeted being affected. The sheet 2 is thereby properly and without Damage deposited on the sheet stack 6.
  • Grippers 3, suction wheels 4 and fans 71, 72, 73 provide the mentioned Sheet guiding elements, which are used for process optimization of actuators the desired state or the required position have to.
  • control elements are controlled via a control device, as shown in Figure 2.
  • the boom control 8 is with a central control unit 19 Printing machine connected, which has a computing unit 20.
  • the Boom control 8 and the central control unit 19 of the printing press exchange data with one another via a data line.
  • the data line 21 extends between a first interface 22 of the boom control 8 and a first interface 23 of the central control unit 19, the first interface 23 of the control unit 19 with the computing unit 20 of the Control unit 19 is connected.
  • the data line 21 is of simplicity for the sake of the data bus of the printing press, preferably a CAN bus, realized.
  • the computing unit 20 of the central control device 19 of the printing press is also connected to the function control units 28, 29 of the various printing units and the function control unit 27 of the investor, which likewise control actuators for their functional area, which are monitored by corresponding sensors.
  • Sensor 30 and actuator 33 are assigned to feeder control unit 27, while sensor 31 monitors actuator 34 of the first printing unit and transmits the measured values to function control unit 28 of the first printing unit.
  • the actuator 35 of the second printing unit is controlled by the function control unit 29 of the second printing unit and monitored by the sensor 32.
  • the number of actuators and sensors is not limited. Any number of control elements can be assigned to each printing unit and feeder.
  • the computing unit 20 of the central control unit 19 has one Control unit 25 for entering commands and commands and one Display unit 24 connected, on which the operator of the state of individual functional units of the printing press is displayed.
  • the central one Control unit 19 is part of a control center of the printing press, which is a central operating and monitoring unit of the entire Represents printing press.
  • This boom control 8 is connected to the servomotors 91, 92, 93 via a first interface 11. Each servomotor 91, 92, 93 controls a fan 71, 72, 73 designed as a fan.
  • the boom control 8 is connected via the same interface 11 to a servomotor 13 for the suction wheel 4 and a further actuator for the gripper 3 in the form of a linear motor 12.
  • the boom control 8 has a computing unit 10 which is connected to a plurality of sensors 14-18 via an internal, bidirectional data line and via the interface 11, each sensor 14, 15, 16 being a servomotor 91, 92, 93, the sensor 18 the Actuator 13 for the suction wheel 4 and the sensor 17 is assigned to the linear motor 12 for the gripper 3 for monitoring the position.
  • the monitored position of the respective actuator is reported back to the boom control 8.
  • the sensors 14-18 can be designed, for example, as a potentiometer.
  • the boom control 8 evaluates those supplied by the sensors 14-18 Signals about the actual position of the servomotors 12, 13, 91, 92, 93 and generates control signals as a setpoint for each servomotor 12, 13, 91, 92, 93.
  • the displayed error message is deleted and it is done via the Display device 24 prompts the operator to identify the defective one Bring servomotor 12, 13, 91, 92, 93 into a desired position by hand. After doing this, the operator presses the button 26 one more time, whereby the central control unit 19 the completion of the made manual setting is communicated. From this point on, the Position sensor of the servomotor 12, 13, 91, 92, 93 the manually set Setpoint as actual value and the boom control 8 works in the further course only with this value.
  • the defective actuator is quasi by the Operator simulated.
  • Such a simulation is independent of the actuator and can be used for position or linear motors are used in exactly the same way as for pneumatic cylinders, so that with automated processes like those in today Sheetfed offset presses occur on one or more actuators can easily be bridged manually and a failure of the entire system can be avoided.
