Definitions

  • the invention relates to an arrangement for prevention of printing unit damage to web-fed rotary printing presses according to the preamble of claim 1.
  • a rotary motor is a hydraulic accumulator assigned to a cylinder in a print stop too bring.
  • the invention has for its object a Arrangement to prevent damage to the printing unit To create a power failure.
  • the invention has the following advantages in particular: As a result of the arrangement of an energy store which, in the event of a failure of the electrical supply, briefly releases energy for actuating a control unit, which in turn causes at least one blanket cylinder to pivot for each printing unit in operation, winders have become harmless when the paper web is torn.
  • the blanket cylinders 2 to 5 are pivoted for example, in that each journal 17 one each blanket cylinder 2 to 5 each in one Side frame 22 rotatably arranged eccentric bush 18 is mounted, with each eccentric bushing 18 an eccentric bush fixed flange 19 by means of a Coupling 21 and a side frame fixed Angle lever 23 with the end remote from the piston Piston rod 24 of the working cylinder 16 is connected.
  • the working cylinder 16 is on its piston rod remote End fixed on the side frame.
  • Parts 16 to 19 and 21 to 24 are duplicate and are - besides that Side frame 22 - referred to as adjusting means 26.
  • the Directional control valve 29 has one in its central position Lock position on.
  • a supply and return line 33, 34 of the Directional control valve 29 is with a known compressed air reservoir 35 with connection 40 to a known generating plant connected.
  • the first solenoid actuator 31 of the directional valve 29 is with break contacts 36, 37 of a first limit switch 38 in connection, which is fixed to the side frame in the Near the journal 17 of each blanket cylinder 2 to 5 is attached and its contact operating lever with an eccentric bush fixed cam 58 in non-positive connection.
  • NO 41, 42 in a second limit switch 43 are also fixed on the side frame near the axle journal 17, however at another point on the circumference of the eccentric sleeve 18 arranged.
  • the contact operating lever of the Limit switch 43 is depending on the location of the blanket cylinder with the surface of the cylinder liner 18 or with a cylinder liner-fixed cams 59 in non-positive Connection.
  • Both the opener 36 of the first limit switch 38 and also the closer 41 of the second limit switch 43 stands with a first connection of an opener 44 Relay 46 in connection. Parts 29, 31, 32, 38, 43, 46 are designated as control means 47.
  • An opener 37 of the limit switch 38 and a closer 42 of the limit switch 43 are on the one hand on the Operating voltage UB, e.g. B. 24 volts DC, on and on the other hand are one with inputs E1, E2 programmable logic controller 45 (PLC) connected. Outputs of the PLC 45 are via a current return preventing diodes 48, 49 in parallel with the contacts 36, 41 of the two limit switches 38, 43 switched to a switch position indicator of the limit switches 38, 43 for the case of restart after a failure of the to signal electrical supply.
  • PLC programmable logic controller 45
  • the control means 47 are with a Electrical energy storage 51 connected, which consists of a capacitor 54 connected to ground 53 UB, which is preceded by a diode 52.
  • the diode 52 is a resistor 55 for current limitation upstream.
  • a Protective resistor 61 e.g. B. of a kiloohm be.
  • the capacitance of the capacitor 54 can be 2 times 10 nanofarads at 40 volts. That of the diode 52 upstream resistor 55 can be 1 ohm.
  • the arrangement works as follows: During the operating state, in addition to the Motor drives for the printing press, not shown, also the blanket cylinders 2 to 5 of the satellite printing unit 12 in operation, so that the blanket cylinder 2 and 3 against each other and the blanket cylinders 4 and 5 work against the impression cylinder 1.
  • the against Ground 53 lying capacitor 54 is during the Operation by the concern of the operating voltage UB charged. That parallel to the energy storage 51 switched relay 46 has during operation tightened so that the opener 44 is open. Consequently have not addressed the control means 47.
  • the normally closed 44 of the relay 46 closes the normally closed 36, 37 of the limit switch 38 are open and the Normally open contacts 41, 42 of the limit switch 43 are closed.
  • the contact operating lever of the limit switch 43 is in connection with cam 59 remote from the eccentric sleeve when the piston 57 of the working cylinder 16 is actuated from the right working position D to the print stop C.
  • the limit switch 43 switches from, so that the closer 41, 42 open and the Print stop C of the blanket cylinder 5 reached is (dashed line in Fig. 2), so that Paper winder can be avoided.
