Definitions

  • the invention relates to a printing press with at least one forme cylinder with an interchangeable sleeve carrying a printing form.
  • a printing press is known from US Pat. No. 5,186,103 which is used in particular for printing on a paper web made of heavy or hard cardboard material and which has interchangeable cylinders. Since the images to be printed have different widths and lengths according to the different packaging materials to be printed, it is necessary to use and replace forme cylinders with different diameters. Either only the forme cylinder (for direct printing) or the forme cylinder together with the transfer cylinder (for offset printing) is arranged in an exchangeable cassette the respective printing tower of the printing press is removable.
  • a winch which is movably arranged on a rail, serves to remove it. It first pulls the cassette up and then transports it away to be exchanged for another cassette with a forme cylinder or a forme cylinder in connection with a transfer cylinder which has a different diameter.
  • printing machines with means for storing the forme cylinders in the correct circumferential and lateral register are known.
  • An offset printing machine is known from EP 0 453 973 A1, in which, when the format of the printing form is changed, both the forme cylinder and the transfer cylinder and the impression cylinder are each replaced by another forme cylinder, transfer cylinder or impression cylinder.
  • the cylinders are transported by a cart.
  • This machine is suitable for replacing a forme cylinder which carries a printing form in the form of a sleeve holding non-positively on its jacket and has the features of the preamble of claim 1.
  • a printing machine for direct printing is known from WO 92/07716, the printing form of which is formed by a thin film.
  • the printing film is imaged within the printing machine by means of an imaging device.
  • the printing form can also be changed by a robot.
  • a form cylinder that is covered with a renewable printing form is particularly suitable.
  • the printed printing form can be deleted by an erasing device and then re-imaged. This is done for example by an ink printing process or by a thermal transfer process with a film that covers the forme cylinder. Sufficient time is therefore available for the renewal of the surface of the forme cylinder.
  • the fact that the forme cylinder is unloaded from the printing press and is not imaged again in the printing press does not result in any space problems for the imaging unit.
  • the invention creates defined interfaces between the printing press, ie the mounting of the forme cylinder in the side walls of the printing press, and the forme cylinder itself.
  • bearing sleeves for the forme cylinder, forme cylinder tensioner and spur gears between the cylinder bearing and the forme cylinder are provided, for example, in the side walls in the direction of the longitudinal axis of the forme cylinder.
  • the storage magazine which is used to replace the forme cylinders, preferably has a drum store in which one or more forme cylinders are stored for replacement.
  • the gripping, rotating and lifting elements with which the forme cylinder is removed from the printing machine and exchanged for another forme cylinder are preferably designed in the manner of such devices as are used in machine tools, e.g. CNC machine tools, used.
  • the forme cylinder carries the printing form as an exchangeable sleeve.
  • the sleeve can be easily removed if the forme cylinder is first taken out of its storage by a removal arrangement, so that the sleeve can then preferably be pulled off vertically downward on one of its pins when the forme cylinder is suspended.
  • the weight of the sleeve contributes to the fact that it can be easily removed due to gravity.
  • the change of the sleeve can thus be carried out without having to provide holes in the side walls of the respective printing unit or having to arrange a bearing in one of the pins of the forme cylinder, about which this should be pivotable for changing the sleeve.
  • a sheet printing machine 1 (Fig. 1) comprises a sheet storage 2 with the sheets to be printed, a sheet feeder 3, which applies the sheets to a printing cylinder 4, on the circumferential surface of which they are transferred from a forme cylinder 5 via a transfer cylinder 6 Offset printing processes can be printed.
  • the printed sheets are transported from the printing cylinder 4 to a take-up drum 7. It transfers this to a printing cylinder, not shown here, of a further printing unit of the sheet-fed printing press 1.
  • the sheet-fed printing press 1 is equipped with an exchange unit for changing the forme cylinder 5, which in turn comprises a gripper 8, a lifting device 9 and a double gripper 10 which is mounted in its own frame 11.
  • the double gripper 10 already carries a forme cylinder 5 'which is to be exchanged for the forme cylinder 5 when its printing form is printed or when another print job is to be carried out. It acts as a cylinder changing device.
  • the gripper 8 is, for example, fastened pivotably in the directions of a double arrow A in the side walls 11 of the sheet-fed printing press 1.
  • the gripper 8 has two gripper arms 80, each of which is equipped at its ends with a leg 82 and a clamping device 81, which are inserted into a receiving means, e.g. a receiving groove 51 (FIG. 10) in a pin 520 of the forme cylinder 5 fit into the side of the end faces of the forme cylinder 5.
  • a receiving means e.g. a receiving groove 51 (FIG. 10) in a pin 520 of the forme cylinder 5 fit into the side of the end faces of the forme cylinder 5.
  • the inking unit rollers 130, 131, 132 of an inking unit 13 of the sheet-fed printing press 1, which are in the swivel range of the forme cylinder 5, are first pivoted away from the forme cylinder 5 with movement means (not shown) (arrow B). Then the leg 82 and the clamping device 81 on the gripping arms 80 of the gripper 8 engage in the respective lateral receiving groove 51 of the forme cylinder 5.
  • the clamping device 81 presses the pin 520 of the forme cylinder 5 against the leg 82, and the gripper 8 moves in the direction the lifting device 9, which supports the forme cylinder 5 in receiving grooves 52 (FIG. 7), also provided for this purpose, in its pin 520 with its two lateral legs.
  • the lifting device 9 has a threaded spindle 91 on the side wall 12 of the sheet-fed printing machine 1 or is movable in the direction of a double arrow C via a toothed rack or via a chain drive.
  • the gripper 8 After the gripper 8 has transferred the forme cylinder 5 to the lifting device 9, it carries the forme cylinder 5 upwards in order to transfer it to the double gripper 10 (FIG. 2). This is already pivoted towards the lifting device 9 for receiving the forme cylinder 5.
  • the double gripper 10 receives the forme cylinder 5 with its two legs in turn in receiving grooves 51 of the forme cylinder 5 on a lever arm 100.
  • the double gripper 10 has in each of its two lever arms 100, 101 a retractable and retractable holding means 102 for clamping the forme cylinder 5 or forme cylinder 5 ', which is to be exchanged for the forme cylinder 5.
  • the double gripper 10 (FIG. 4) then rotates through 180 ° in order to bring the forme cylinder 5 ′ into the receiving position for the lifting device 9.
  • the lifting device 9 is moved up again until it reaches the position in which it takes over the forme cylinder 5 'as soon as the holding means 102 of the double gripper 10 holding it is released.
  • the lifting device 9 is not necessary if the gripper 8 is provided with extendable telescopic arms with which it transfers the forme cylinder 5 directly to the double gripper 10.
  • the forme cylinder 5 While the forme cylinder 5 '(FIG. 5) is now brought into its printing position by the lifting device 9 and the gripper 8 in the same way as the forme cylinder 5 was previously removed from its position in the sheet-fed printing press 1, the inking unit rollers 130, 131 also being taken and 132 down again (double arrow B) be pivoted back, the forme cylinder 5, which is located within the frame 11 of the double gripper 10, is now prepared for a new printing process.
  • An imaging unit 14, such as is shown in FIG. 5, is used for this purpose.
  • the imaging unit 14 is arranged in a frame 140, which is integrated with the side walls 13 of the printing unit of the sheet-fed printing machine 1 and also comprises the frame 11 of the double gripper 10.
  • the imaging unit 14 comprises an erasing device 141.
  • the erasing device 141 is, for example, a plasma torch which is integrated in the axis of rotation of the double gripper 10.
  • the forme cylinder 5 is rotatably mounted in the lever arm 100 of the double gripper 10, which carries it, by a motor, which is not shown here.
  • the imaging unit 14 further comprises an imaging device 142 in order to rewrite the printing form on the outer surface of the forme cylinder 5, for example by means of inkjet or by laser ablation.
  • the imaging device 142 is arranged movably in the directions of a double arrow E on a holder 143, so that it can be pushed to the side during the pivoting movements of the double gripper 10, for example by means of a motor.
  • a fixing device 144 for example an IR radiator, for fixing the image generated by the imaging device 142, which can also be moved out of the swivel range of the double gripper 10.
  • another imaging unit (FIG. 6) can also be provided, which is likewise arranged in a frame 150 and comprises an extinguishing device 151, for example a plasma torch.
  • the imaging unit 15 has an embossing roller 152 with an integrated heater which, in accordance with an image to be produced on the printing form, imprints material from a film 153 onto the forme cylinder 5, the latter being in a position 5a.
  • the embossing film 153 is like a film unwound from a cassette 154, and the used embossing foil 153 is wound up again in a cassette 155. This imaging process takes place while the sheets are being printed with the image applied to the forme cylinder 5 '.
  • the printed image on the printing form is fixed by a fixing device 156.
