Definitions

  • the invention relates to a protective device on printing presses, which are supported by swivel arms on both sides on shaft journals and can be raised from a closed to an open position, the pivoting being supported by a spring element.
  • Such protective devices are used in printing machines, for example, to secure printing units in order to prevent injury to the operator while the machine is running.
  • a protective device is e.g. B. provided in the area of the plate and blanket cylinder.
  • Protective devices of this type are opened or closed by hand, with the machine preventing the machine from running in the open position via a circuit breaker.
  • the operator has to climb onto a running board on the machine in order to open the protective device in order to open the protective device completely.
  • this is also necessary when closing the protective device, so that, for. B. when washing the blanket or the printing plate by hand, an unnecessary effort is required, because it would suffice if the protective device was only raised something that would normally be possible without climbing.
  • a complete opening is only necessary if the printer is also working on the inking and dampening rollers.
  • the protective device is in a half-open intermediate position can be raised in which it rests on a lever supported by the spring element with a first stop on a shaft journal.
  • the printer can e.g. B. change the rubber blanket without having to climb on the machine to move the protective device into a stable open position. This makes the printer's work easier and he can carry out all the necessary operations from a single level.
  • a spring element By using a spring element, he can move the protective device back into the closed position after the work is done.
  • An advantageous embodiment of the invention is characterized in that a shaft journal firmly connected to a swivel arm carries a disk with end-side first and second stops, that a lever is pivotally mounted on the shaft journal, at the outer end of which the spring element is supported by a journal that the spring element and the lever are in an over-center position in the closed position of the protective device and bear against a stop such that when the protective device is pivoted from the closed position, the disk pivots the lever with the spring element from the over-center position into a position with a second stop, in which the spring element is stretched and that, in this position of the spring element, the protective device lies against the lever in the intermediate position via the first stop on the disk.
  • the protective device can be raised from the intermediate position into the open position and in this position rests against a stop fixed to the frame.
  • the angular distance between the first and second stops on the disc is a few degrees less than the pivoting range of the lever, so that the lever with the spring element when pivoting the protective device into the Intermediate position is moved from the dead center position.
  • the spring element is designed as a gas pressure spring.
  • a printing unit 1 of a printing machine which has a plate cylinder 2, a blanket cylinder 3 and rollers 4 of an inking unit.
  • a protective device 5 is provided on the side of the printing unit, which is mounted on swivel arms 6 on both sides on shaft journals 7, 12.
  • the protective device itself is pivotally attached to the pivot arms 6 via pins 8 and has handles 9 for pivoting the same.
  • the protective device 5 can be pivoted via the handles 9 into a half-open intermediate position b or into an open position c.
  • the shaft journal 7 is rotatably mounted in a side frame 10 of the printing press.
  • a shaft journal 12 is also mounted in a side frame 11, to which the opposite pivot arm 6 is fastened.
  • a circuit breaker 13 is arranged on the shaft journal 12, which prevents the printing machine from starting up when the protective device 5 is raised.
  • the shaft journal 7 is shown, on which a swivel arm 6 is secured against rotation within the side frame 10.
  • the shaft journal 7 is rotatably mounted in the side frame 10 via bearing bushes 14.
  • the shaft journal 7 is mounted in a bearing plate 15 which is fastened to the side frame 10 by means of stud bolts 16.
  • the shaft journal 7 carries a disk 17 which is connected to the shaft journal 7 in a rotationally fixed manner.
  • a bearing journal 18 is provided on the shaft journal 7, on which a lever 19 is pivotably mounted.
  • a pin 20 is provided, on which a spring element 21 is supported with its spring rod 22.
  • the spring element 21 is mounted on a support pin 23 which is fastened in the end shield 15.
  • the swivel arm 6 of the protective device 5 is shown in a position in which the protective device is closed according to a.
  • the spring element 21 and the lever 19 are in a dead center position and are supported on a stop 24, which is attached to the bearing plate 15.
  • the disk 17 rotates until a second stop 25 hits the lever 19 and takes it along until the dead center position has been overcome and the spring element 21 continues to pivot the lever 19, until the spring element 21 assumes an extended position (FIG. 5).
  • the protective device 5 is in position b and the spring rod 22 is fully extended.
  • a first stop 26, which is fastened to the disk 17, lies against the lever 19 and thus supports the protective device 5 in this position.
  • the swivel arm 6 assumes the position shown in FIG. 6.
  • the disc 17 has rotated so far that the second stop 25 and the first stop 26 no longer come into contact with the lever 19.
  • the swivel arms 6 lie against a stop 27 fixed to the frame (FIG. 1).
  • the spring rod 22 and the lever 19 do not change their position compared to the position shown in FIG. 5.
