Definitions

  • the invention relates to a method for accurately feeding printing plates from a Plate magazine, in which the printing plate is provided in the plate magazine and for Purpose of printing plate change released by this, through funding between one a pair of clamping rails arranged in an axially parallel channel of the plate cylinder Spent clamping device and there the target position of the pressure plate by their contact with two test points is checked and, if the pressure plate is not in the desired position in the Clamping device reached, the funding then releases the pressure plate.
  • a solution is known from EP 0 581 212 A1 in which two are at a finite distance pins arranged in relation to one another and electrically insulated from the clamping rail are provided. If both pins lie on the front edge of the pressure plate, the Pressure plate closed a circuit between the pins and generated a signal. In order to the clamping rails can be closed. This clamps the pressure plate and can be clamped onto the plate cylinder by suitable devices.
  • DE 44 39 623 C2 describes a method for automatically feeding printing plates become known for the plate cylinder of a printing press, in which by are in contact with the pressure plate, the front edge of the pressure plate in a clamping rail the plate cylinder is inserted. There is the register-correct position of the pressure plate checked. This is done on two spaced apart in the axial direction of the plate cylinder Locations in the clamping rail. If this is given, that is, the pressure plate is on both Locations at a dowel pin arranged there for this purpose, the pressure plate in the clamping rail fixed. If this is not the case and the pressure plate is only due to a dowel pin for a predetermined time interval is a release of the printing plate by the funding triggered. The pressure plate now has the opportunity to relax and on To take a new direction due to their own weight. After that, the contact between the pressure plate and conveying means restored and the pressure plate back in Directed the dowel pins.
  • Another disadvantage is that not all conveyor systems are suitable, a brief release and to realize a subsequent repeated gripping of the pressure plate.
  • the object of the invention is to avoid the disadvantages mentioned above To develop a process by which a register position in the clamping rail is achieved and the pressure plate experiences a minimal mechanical load.
  • the advantage of the solution according to the invention is that now the automatic Feeding the printing plates can be done more interference-free.
  • the misalignment of the printing plate can be corrected without manual intervention by the operator
  • the device required to implement the inventive method is in the Figure 1 shown.
  • a plate magazine 2 Pressure plate 1 temporarily stored.
  • the plate magazine 2 is in its rest position firmly attached to the frame of the printing machine, not shown.
  • a plate cylinder 4 is also mounted in the frame Surface to receive the printing plates 1 fed from the plate magazine 2.
  • a plate cylinder channel 41 on its circumference in the axis-parallel direction arranged.
  • a clamping device 5 is located in the plate cylinder channel 41 from an upper clamping rail 52 and a lower clamping rail 51.
  • the upper clamping rail 52 is fixedly arranged on the plate cylinder channel 41.
  • the lower clamp rail 51 is against the upper clamping rail 52 for clamping the pressure plate 1.
  • the clamping device 5 are assigned in the area of the clamping rails 51, 52 dowel pins 54a, 54b. It can be seen from FIGS. 2 to 4 that the dowel pins 54a, 54b are in a finite, the distance between the pre-alignment pins 21a; 21b corresponding distance to each other are arranged.
  • a clamping and tensioning device 6 is mounted in the plate cylinder channel 41. In FIG. 1 is only hinted at. The clamping and tensioning device 6 serves to receive the end of the pressure plate 1.
  • the plate magazine 2 is equipped with a Pressure plate 1 loaded and from its rest position to the position for changing the pressure plate hazards.
  • the plate cylinder 4 is positioned so that a constellation is created which enables the insertion of a pressure plate 1 into the clamping device 5. This position is shown in Figure 1.
  • the pressure plate 1 is pre-positioned in the plate magazine 2 by the pre-alignment pin system.
  • a printing plate 1 is released from the plate magazine 2, by withdrawing the pre-alignment pins 21a, 21b.
  • funding agencies come into play in contact with the pressure plate 1.
  • suction devices are used as conveying devices 3 provided. However, transport rollers and other facilities are also possible. This capture the printing plate 1 and convey it from the plate magazine 2 in the direction of the open Clamping device 5. In this position, the lower clamping rail 51 is from the upper The clamping rail 52 is retracted and is located in the upper clamping rail 52 most distant position.
  • the pressure plate 1 with its punched-out portions 12a; 12b on dowel pins 54a; 54b driven. Is the pressure plate 1 in the register-correct target position (see Figure 2) is the contact between the electrically conductive pressure plate 1 the dowel pin 54a and the dowel pin 54b closed.
  • the contact points dowel pin 54a / punching 12a and dowel pin 54b / punching 12b independently queried. With this, a distinction can be made whether a system at both contact points, at one of the contact points or is not given at any of the contact points.
  • the pressure plate 1 is returned to the suction cup 3 Record magazine 2 funded.
  • the contact between the suction cup 3 and the pressure plate 1 is not interrupted in any phase, i.e. the vacuum cleaner 3 remains until this point in contact with the pressure plate 1.
  • the printing plate 1 is only placed in the plate magazine 2.
  • the storage is again carried out on the pre-alignment pins 21a, 21b.
  • the pressure plate 1 now has Opportunity to reposition yourself and can take a second if necessary can also be removed from the plate magazine 2 for further experiments.
  • the contact between the suction cup 3 and the pressure plate 1 is interrupted and the suction cup 3 moves back to its starting position without pressure plate 1.
  • External means of moving the printing plate 1 are associated with this and promote the printing plate 1 on the clamping device 5.
  • These external means can be rubberized, for example Rollers or conveyor belts that are brought into contact with the pressure plate 1 and promote this in the direction of the clamping device 5.
  • Another embodiment of the invention is by means known per se after loosening the suction cup 3, the pressure plate 1 or the clamping device 5 by suitable to vibrate electromagnetic or pneumatic means and after a appropriate position to check the position of the pressure plate 1 again.
  • multiple attempts may be required.
  • the measures described above are combined combined. So after releasing the suction cup 3, the pressure plate 1 can vibrate are and at the same time the clamping device 5 with or without the plate cylinder 4 several times be guided in the direction of the pressure plate 1.
  • the dowel pins 54a and 54b are the correct ones Target position of the pressure plate 1 is reached in the course of the further process the clamping device 5 closed.
  • the plate cylinder 4 begins to rotate, whereby a roller, not shown, is placed on its circumference. This roller ironed the Pressure plate 1 on the plate cylinder 4 and ensures their smooth support on the surface of the plate cylinder 4.
  • the pressure plate 1 is in the Clamping and tensioning device 6 pressed, detected there and clamped.
  • a not shown Mechanism exerts a tangentially directed force on the clamping rails of the tensioning device off, so that the pressure plate 1 is tensioned.
