Definitions

  • the invention relates to a security system for a printing press, which is provided with at least one drive and brake device and with an electronic control device.
  • the various drives of a printing press are provided with brakes, in which the braking force is exerted by springs and a corresponding voltage is applied to electromagnets to release or release the brakes.
  • the brakes are used both as service brakes and for emergencies. This leads to undesirable wear on the brakes.
  • emergency stop switches are provided at various points on the printing press and possibly also in the vicinity thereof, with the aid of which the printing press can be stopped. So that the motors can be stopped and the brakes can be applied without electrical auxiliary energy, the known stop devices in known safety devices are each provided with a normally closed contact and connected in series.
  • the safety system according to the invention is characterized in that the electronic control device comprises power levels which allow the drive device to be braked electronically, that the electronic control device further comprises a monitoring circuit which sets and actual values of the speed of the drive device can be fed and which actuates the brake device when one there is an impermissibly high deviation between the setpoint and actual value, and that the accelerations and decelerations required during operation of the printing press are achieved by appropriate control of the drive device.
  • the measures according to the invention ensure that the motion sequence of the printing press is controlled purely electrically, so that predetermined delays are also possible.
  • the brakes are only required if errors occur in the electronic control device.
  • the braking device is actuated by an electromag releasing the brake against a spring force net is switched off.
  • the braking device is designed in accordance with another development such that the printing press also comes to a standstill can be brought when the drive device applies the highest possible torque.
  • the monitoring circuit emits control signals for stopping the printing press to the power stages before the actuation and checks again the deviation between the setpoint and actual value of the speed.
  • the braking device is checked by actuating the braking device, controlling the driving device for the highest possible torque and evaluating the actual speed value. The check is preferably carried out after the electronic control device is switched on.
  • Another development of the security system according to the invention is characterized in that several emergency switches each have first and second contact pairs which can be operated in parallel, that the first contact pairs are connected in series and form a safety circuit, and that the second contact pairs are individually connected to inputs of the electronic control device.
  • a special embodiment of this development consists in that the safety circuit is supplied with AC line voltage and that the primary winding of a transformer is connected in series with the first contact pairs, the secondary winding of which is connected via a rectifier to the power stages of the monitoring circuit and the computer or computers.
  • This configuration makes it possible to adapt the safety circuit to semiconductor circuits without the voltage supplying the safety circuit being so low that a safe current flow is called into question by the series connection of many contacts.
  • the additional information obtained through the additional contact pairs can be evaluated in various ways.
  • the emergency stop switches are used to bring the entire machine to a standstill as quickly as possible in the event of a danger. However, malfunctions are possible which only require the machine to be stopped in successive steps.
  • a main drive 61 and various auxiliary drives, of which only two auxiliary drives 71, 72 are shown, are controlled by two computers 52, 53.
  • the computers 52, 53 are connected to one another and to control electronics 56 with the aid of a bus system 55.
  • a main drive electronics 6 and an auxiliary drive electronics 7 each comprise, in addition to power stages, also associated control stages which, in a system according to the invention, are equipped with microprocessors, among other things.
  • Control electronics 56 has a variety of functions and includes various components. To understand the present invention, however, only the explanation of a monitoring circuit, which is part of the control electronics 56, is required.
  • the monitoring circuit is supplied by a tachometer 9 with the actual value of the machine speed or the speed of the main drive.
  • a setpoint is supplied via the bus system 55.
  • the control electronics supply two contactors (not shown in FIG. 1) with current, so that the main drive brake is released.
  • the monitoring circuit in the control electronics 56 sends signals to the main drive electronics 6 when a permissible deviation between the setpoint and actual value is exceeded in order to shut down the main drive 61.
  • the machine speed will drop rapidly as a result of the electrical braking when a signal is issued by the monitoring circuit for stopping the main drive, so that further measures are not necessary.
  • the printing press can be stopped by actuating the main drive brake 60.
  • the monitoring circuit sends a signal to the ignition pulse lock to the main drive electronics 6 in order to avoid that the main drive 61 continues to be supplied with current. if the defect in the main drive electronics 6 allows this.
  • the monitoring circuit also monitors the function of the computers 52, 53 and can, if one computer fails, transfer security-related functions to the other computer.
  • the monitoring circuit monitors the auxiliary drive electronics 7, the auxiliary drives 71, 72 and a braking device 70 assigned to the auxiliary drive 71.
  • an emergency stop signal is triggered by a corresponding device 57, it is sent to the computers 52, 53, to the main drive electronics 6, to the auxiliary drive electronics 7 and to the control electronics 56. If there is no defect in the electronic control device, the printing press is stopped as described above without using the brakes. Only when there is a defect that prevents this, the printing machine is stopped using the brakes.
  • Fig. 2 shows emergency stop switches 11 to 1n, which are connected to an electronic control system for a printing press.
  • the latter consists of an input / output unit 4, a computing unit 5 and power units 6, 7, which are assigned to motors 61, 71.
  • the power units essentially correspond to the main drive electronics 6 and the auxiliary drive electronics 7 (FIG. 1).
  • FIG. 1 For the sake of clarity, only two motors, namely the motor 61 of the main drive and a motor 71 of an auxiliary drive, have been shown, although pressure measure machines can have significantly more motors.
  • the design of the electronic control system in detail is possible in a variety of ways without departing from the scope of the invention.
  • the input / output unit 4 comprises two input / output cards 41, 42, each of which has a multiplicity of inputs and outputs 43, 44.
  • the input / output cards 41, 42 are connected to one another and to the input / output control card 51, which contains the monitoring circuit, among other things, of the computing unit via a bus system 45.
  • the computer unit 5 also includes a memory card 54 for storing data, for example data from the printing press and data from the jobs to be processed.
  • a memory card 54 for storing data, for example data from the printing press and data from the jobs to be processed.
  • non-volatile memories are provided on the memory card 54.
  • the programs themselves were stored in read-only memories which are arranged on the cards of the computers 52 and 53.
  • a bus system 55 connects the input / output controller 51, the computers 52, 53 and the memory card 54.
  • the input / output unit 4 is provided for binary signals (for example, switch closed, switch open; relays attract, relays drop out), digital signals are output which are used to control the power units 6, 7 and thus of the motors 61, 71 are used via the input / output control 51.
  • the input / output control 51 is also supplied with a signal corresponding to the machine speed by a tachometer 9.
  • An electromagnet 63 for releasing the brake is supplied with operating voltage supplied at 66 via two contacts 64, 65 of two contactors 67, 68.
  • the contacts 64, 65 are designed as working contacts, so that the brake is only released when both contacts 64, 65 are closed, which in turn is only the case when both contactors 67, 68 from the input / output unit 4 with Voltage are supplied.
  • the emergency switches of which only the emergency switches 11, 12, 13 and 1n are shown for the sake of clarity, can be provided with mushroom push buttons. However, other actuating devices, such as levers, tread strips and switches, which are actuated when protective guards are opened, can also be provided.
  • Each of the emergency switches 11 to 1n has two contact pairs 21 to 2n, 31 to 3n working as a normally closed contact.
  • the respective first contact pairs 21 to 2n are connected in series and connect a connection 1 provided with mains voltage to the primary winding 81 Transformer.
  • a rectifier 83 is connected to the secondary winding 82 of the transformer. There is thus a galvanic separation between the safety circuit formed by the series connection of the respective first contact pairs and the primary winding 81 and the subsequent circuits. In addition, the switching voltage is reduced to a value suitable for controlling semiconductor circuits, while the voltage supplying the safety circuit has a sufficiently large value to ensure safe current flow despite the series connection of many contact pairs.
  • Corresponding inputs of the power units 6, 7, the computers 52, 53 and the input / output controller 51 are connected to the safety circuit via a contactor 84.
  • the respective second contact pairs 31 to 3n of the emergency switches 11 to 1n are connected to inputs of the input / output unit 4 of the electronic control system.
  • the printing press is nevertheless operated via the stopped by the respective first contacts 11 to 1n, the transformer 81, 82, the rectifier 83 and the protection 84 safety circuit.
  • the braking device 60 Only when the electronic control device is unable to stop the printing press by means of electrical braking, is the braking device 60 actuated, as described in connection with FIG. 1.
  • the contactors 67, 68 are de-energized, whereby the magnetic coil 63 is separated from the operating voltage supplied at 66 with the aid of the contacts 64, 65. 2, the control of the contactors 67, 68 takes place via the input / output unit 4, but two separate output circuits are provided for the contactors 67, 68 to ensure a high level of security.
  • switches 85, 86 can be connected to inputs of the input / output unit 4. These switches can be used to call up programs which result in a targeted shutdown of the printing press in accordance with the respective situation.
