Definitions

  • the invention relates to a device for controlling remote actuators a printing press according to the preamble of claim 1.
  • the sheet brakes have servomotors and position sensors and are connected to a controller via a bus system.
  • a Such a device is known from DE 197 17 297 A1.
  • the single ones Actuators (sheet brakes) are additionally provided with sensors, by which an approximation of a sheet brake compared to an adjacent sheet brake lockable and the corresponding actuator can be stopped. Thereby Avoid collisions.
  • a control computer is known from DE 43 42 052 A1, which is connected to a plurality of peripheral units via an address bus.
  • the address recognition circuits of the individual peripheral units each have an E 2 PROM, which can be actuated by a trigger circuit that can be activated by an operator.
  • addresses assigned by the control computer are permanently stored in the E 2 PROM of the peripheral unit.
  • From DE-A-3 413 179 is a control and regulating device of a sheet delivery for Sheet processing machines, especially known for sheet printing machines.
  • the Boom suction wheels can be adjusted remotely.
  • the suction wheels each contain a geared motor, the pinion with a transverse Rack is engaged.
  • the object of the present invention is therefore a device for control remotely adjustable actuators of a printing press according to the preamble of Claim 1 to develop in such a way so that without great engineering effort a simple, easy-to-use controllability that has to be changed frequently Actuators is possible.
  • an absolute position detection system is assigned to the actuators mounted on the common traverse and movable along this traverse, by means of which each individual remotely adjustable actuator can detect the current position.
  • the actuators connected to the controller via a common bus are provided with an address to be used for the further control processes, for example after an actuator has been installed or uninstalled on the crossbeam or generally every time it is switched on, in an address assignment mode.
  • the controller sends a signal corresponding to a specific position range via the common bus, which signal can be identified by a position detection circuit within the actuator which lies in this position range.
  • the actuator that is in the respective position range then takes over the address previously, simultaneously or subsequently sent via the bus and stores this value (address) in a non-volatile, rewritable memory (eg E 2 PROM).
  • a non-volatile, rewritable memory eg E 2 PROM
  • a RAM can also be provided as the address memory, if the address assignment according to the invention takes place in principle with each switch-on process. Saving of the assigned address is acknowledged by the control element opposite the controller.
  • the overall length of the traverse or the Traverse associated absolute position measuring device scanned so that thereby each on the traverse and with the position detection device connected actuator recognized and in the manner described with an address can be provided.
  • the control system delivers and Position ranges corresponding signals such that the width of each activated position range is smaller than the width of the narrowest actuator.
  • the absolute measuring system for the position of the actuators on the crossbar can be an analog or digital potentiometer.
  • the absolute measuring system can also be an optical, act magnetic or inductive measuring system. So it is possible that parallel to the cross-beam receiving the individual actuators scanning bar is arranged which is arranged by a connected to the actuator is scanned. Depending on the position the traverse on which the actuator is located is by the sensor and a downstream evaluation unit generates a signal which is a measure of the Position of the actuator is. This signal is then described in the above Way for the address allocation provided by the invention the control used.
  • the address assigned in this way remains for the Actuator valid, i.e. Every actuation process of this actuator takes place via this Address, whereupon the intended address after addressing via the bus system Position command (specification of the target value to be approached) is sent.
  • the one in Actuator is then arranged in the predetermined direction controlled until the actual value (actual position value) delivered via the absolute measuring system matches the sent setpoint.
  • the common bus system via connectors with the Actuators and the controller connected.
  • the controller has one Number of connectors, this being the maximum number of on the Cross member to be installed corresponds to actuators.
  • an additional actuator must be installed, so an operator only make a plug connection between the control and the actuator.
  • the individual actuators in the manner of struck plug connections on one common bus cables are connected, the distance of the common Bus cable arranged connectors the greatest possible distance corresponds to two actuators on the crossbar.
  • the bus cable folds accordingly the positioning of the actuators on the crossbar. Becomes a installed new actuator on the crossbar, the operator only has the free connector on the bus cable with a corresponding slot on the Connect actuator.
  • a contactless bus system can be provided.
  • address and Control data for example, transmitted by radio.
  • acknowledgment signals between the actuators and control are identical to acknowledgment signals between the actuators and control.
  • Fig. 1 shows a common traverse 3, on which as suction belts, suction rings or other devices trained actuators 1 arranged movable are.
  • the absolute extends parallel to the traverse 3 in the form of a rail Measuring system 2, which is designed for example as a potentiometer.
  • the Individual actuators 1 are connected to a controller 4 via a bus system 5.
  • the line system of the bus system 5 between the controller 4 and the individual actuators 1 has plug connections, not shown, so that an actuator 1 to be removed from the crossbar 3 is separated from the control 4 or an additional actuator 1 to be installed on the crossbar 3 with the Control 4 can be connected.
  • Fig. 2 shows the components assigned to an actuator for assigning addresses.
  • the actuator 1 connected to the common bus system 5 has one Controller 10, which is in signal connection with an actuator 11.
  • the Controller 10 receives the corresponding control commands via bus system 5 and is connected to this via a switch 8. In normal operating mode 8 control commands are supplied to the controller 10 via the changeover switch in order to the actuator 11 to move the actuator 1 along the cross member 3.
  • To the controller 10 is in signal connection with an encoder 6 which is connected to the Rail of the absolute measuring system 2 interacts and its signals Measure for the position of the actuator 1 on the cross member 3.
  • the switch 8 is followed by a comparator 7, to which the signals of the encoder 6 are also fed.
  • the comparator 7 is still in signal connection with an address memory 9 (E 2 PROM).
  • the address memory 9 is also connected to the controller 10, so that during the normal operating mode, the actuator 1 can be addressed by an address recognition circuit arranged in the controller 10 and can be moved in the desired manner by sending corresponding position commands.
  • the switch 8 is activated and the sent over the bus system 5 and a predetermined position range corresponding signals switched directly to the comparator 7.
  • the Position signals supplied by the encoder 6 are not within the range via the bus system 5 signals sent and corresponding to a position range, that is Actuator 1 not addressed and no address is assigned to it Actuator 1.
  • the comparator 7 recognizes the position signal supplied by the encoder 6 than within the position range, then the is subsequently on the Bus system 5 sent address stored in address memory 9 and is thus available for the further positioning processes.
