Definitions

  • the invention relates to a device designed as a magazine for removing (removing) printing plates from a printing plate cylinder of a printing press, in particular for an automatic or semi-automatic printing plate change / with a plate removal device which has activatable (first) holding means for the respective printing plate.
  • a device of the type mentioned is known from European patent application 0 435 410. It serves to automate a printing plate change.
  • the magazine records old, used records.
  • the printing plate used is unclamped at one end on the printing plate cylinder and then - by appropriate rotation of the printing plate cylinder - partially inserted into the magazine. The other end of the pressure plate is then removed from the clamping device
  • Printing plate cylinder released and the entire printing plate with the plate discharge device inserted into the magazine. Then a new printing plate to be used is then removed from the magazine by means of the plate feed device. First, one end of the printing plate is inserted into the corresponding clamping device of the printing plate cylinder and clamped there and then - by rotating the printing plate cylinder - the printing plate is completely pulled out of the magazine and around the outer surface of the printing plate cylinder. Then the other end of the pressure plate is clamped and there is a clamping in the circumferential direction.
  • the lattenabriosreinri device of the known device has movable suction cups by means of piston / cylinder unit. Since the cylinder of the piston / cylinder unit has a length corresponding to the piston rod and its If the length of the magazine adjoins the path of movement, a correspondingly long design of the magazine is required.
  • the invention has for its object to provide a device of the type mentioned, which allows the removal of printing plates with a simple structure and safe operation and small designs.
  • the (first) holding means are arranged on a first carriage which can be moved along a first guide approximately over the entire length of the device in the interior of the magazine. Because the first carriage can be moved approximately over the entire length of the device inside the magazine, old, used printing plates can be completely retracted into the magazine cassette in one operation. This would not be possible using a conventional piston / cylinder unit, since the latter itself has a certain length that is not available for the adjustment path.
  • the first holding means are preferably designed as activatable first suction elements.
  • the first carriage can be moved by means of a drive device having a magnetic coupling.
  • the magnetic coupling is not a rigid but a flexible coupling and it is also possible to move the first carriage over the entire length of the device.
  • the Antriebseinr device has a non-ferromagnetic tube that extends along the path of movement of the first carriage and that of a ferromagnetic component attached to the carriage, in particular Steel ring, is longitudinally enclosed and is arranged in the tube with a longitudinally movable magnetic piston from a pressure medium, which forms the magnetic coupling with the ferromagnetic component. So if the magnetic piston is moved in the desired manner in the tube by the pressure medium, the erromagneti see component and thus the first carriage is taken along its guide.
  • the guide preferably consists of two spaced-apart guide parts, in particular guide rods. These preferably run parallel to one another.
  • the two guides are arranged in the side areas of the magazine.
  • the drive device is preferably located between the two guide parts.
  • one of the guide parts can be formed by the drive device. Accordingly, there is a corresponding guide rod on one side of the magazine and on the other side the tube provided with a magnetic piston, the ferromagnetic component, in particular the steel ring, being mounted on the tube longitudinally and thus a guide is also formed.
  • the first holding means can be activated (this also applies to the second holding means mentioned later), that is, their function of holding or not holding the printing plates can be switched on and off. Furthermore, the activation also includes the possibility that the holding means can be displaced transversely to the plane of the printing plates in order to be able to step against the surface of the corresponding printing plate.
  • the holding means are preferably designed as suction members, that is to say they have suction cups which operate by means of a vacuum which can be switched on.
  • at least one of the first holding means itself is also movably mounted on the first carriage transversely to the plane of the pressure plates.
  • the first holding means can not only be lengthened or shortened in the longitudinal direction in the direction of the adjacent pressure plate, but can also be shifted overall in this direction. This is done in an upper position of the carriage by means of a positive control such that the preferably angled printing plate trailing edge of the printing plate used passes under a holding edge of the cassette when it is inserted into the cassette. As soon as the back edge of a used printing plate is removed from the
  • the trailing edge clamping device of the printing plate cylinder has been released and the printing plates have been partially pushed into the interior of the magazine by rotating the printing plate cylinder backwards, the end of the printing plate is gripped by the first holding means.
  • the car is in a lower position.
  • the carriage is then moved into the above-mentioned position, the printing plate cylinder simultaneously making a reverse rotation and thus "unwinding" the printing plate from the outer surface of the printing plate cylinder.
  • the positive control When the carriage is moved into the upper position, the positive control then comes into operation, which shifts the mentioned first holding means and thus the rear edge region of the printing plate in the direction of the cassette receiving the printing plate used, so that the printing plate with the angled trailing edge under the mentioned holding edge of the cassette.
  • the positive control is preferably formed by a run-up slope on which a scanning element for moving, in particular Swiveling, the movably mounted first holding means runs on.
  • the front of the printing plate is acted upon by at least one hold-down device arranged in the lower region of the magazine and is thereby also pressed into the cassette.
  • the hold-down device remains in this position, while the holding means push the printing plate down a little, so that the printing plate leading edge also comes under a holding edge of the cassette.
  • the pressure plate to be removed is thus completely and securely accommodated in the cassette.
  • At least one guide roller for inserting the printing plate used into the cassette is arranged in the lower end of the magazine. This guide roller facilitates the feeding of the old, used printing plates into the magazine cassette.
  • 1 is a printing unit of a printing press in a schematic representation with a magazine located in the starting position
  • Feeding a new printing plate to be used to the printing plate cylinder of the printing press, 4 shows a representation according to FIG. 3, but the printing plate is already clamped on the printing plate cylinder;

  • the magazine 4 is in its starting position (vertical position). In this idle state, the magazine 4 is secured against tipping (locking). Normal machine operation (printing operation) is only possible in this lower, vertical position of magazine 4.
  • the magazine 4 has two receiving shafts 5 and 6, into each of which a cassette 7 or 8 can be inserted from above (FIG. 1).
  • the cassette 7 is used to hold old printing plates already used in the printing press 3.
  • the cassette 7 is designed such that it can accommodate several, for example five, used printing plates. These printing plates form a stack of printing plates in the interior of the cassette 7, that is to say the individual printing plates lie flat on one another.
  • the cassette 8 is used to hold new printing plates that are still to be used. It can also have several, in particular five printing plates at the same time record, whereby these pressure plates are also assigned to each other *. To remove the printing plates used, it is therefore only required to pull the cassette 7 out of the receptacle 5.
  • the cassette 8 can be equipped with new printing plates that are still to be used. If this has taken place, the cassette 8 is inserted into the receiving shaft 6 of the magazine 4, so that it is available for feeding to the printing plate cylinder 1 of the corresponding printing unit 2.
  • the individual positions of the magazine 4 which are assumed for removing and / or feeding printing plates are explained below. If a printing plate 9 to be used is to be fed to the printing plate cylinder 1, the magazine 4 moves - according to FIG. 2 - vertically upwards into a central position and then swivels - according to FIG. 3 - into an inclined position (for example about 45 °). By means of a plate feeder of the magazine 4 to be explained in more detail, the printing plate 9 to be used is then fed to the printing plate cylinder 1 and clamped thereon (FIG. 4).
