Definitions

  • the invention relates to a printing unit for offset printing, with a transfer cylinder between a plate cylinder and arranged an impression cylinder and with this means a gear is connected to a drive for turning of said cylinders, being between the transfer cylinder and a substrate can be printed on the impression cylinder.
  • Printing units of the type mentioned are known and are by the Muller Martini Druckmaschinen GmbH, DE-79689 Maulburg. With such printing units, for example, continuous products can be produced in web offset processes with high quality and Performance can be printed.
  • the transfer cylinder, the plate cylinder and the impression cylinder are in one drawer stored, which can be replaced by means of a rail system or pallet truck is.
  • the transfer cylinder is especially a blanket cylinder.
  • the rubber blanket is interchangeably attached to the cylinder in a known manner.
  • Between the transfer cylinder and the impression cylinder runs through an endless path, for example printed here. Usually there are several such printing units arranged one after the other. The endless products go through this Printing units and are each in a printing unit with a Color printed.
  • the invention has for its object a printing unit to create the type mentioned, with the changing print images, such as for example addresses or numbers inexpensively and without Plate changes can be printed.
  • the object is achieved in a generic printing unit in that the plate cylinder has a plurality of print images on its circumference and the transfer cylinder has a transfer segment that cooperates with only one of these print images on its circumference, and that the plate cylinder is connected to an adjustment drive with which it rotates relative to the transfer cylinder its axis is rotatable in such a way that the transmission segment works together with another of the several printed images.
  • the printing unit according to the invention several different pieces of information can thus be printed with a single printing plate.
  • the printed images on the plate cylinder are, for example, strip-shaped areas which are arranged one behind the other in the circumferential direction. Each printed image is provided with information, for example with an address, a number or a bar code.
  • the plate cylinder When printing, only one of these print images works together with the transfer segment of the transfer cylinder. If another piece of information is to be printed, the plate cylinder is rotated with the adjustment drive in such a way that the desired further printed image works together with the transfer segment. Such a rotation of the transfer cylinder is possible, for example, by means of a superposition drive (servo drive) or a separate drive while the plate cylinder is running. After turning the plate cylinder, only a few formats of waste are created.
  • a superposition drive servo drive
  • a separate drive while the plate cylinder is running.
  • the print image can be changed.
  • the print image is as mentioned, for example, an address, a number or a barcode.
  • other printed images are also conceivable here.
  • a preferred use of the printing unit is in particular here printing mailings, brochures and signatures, for example different depending on the customer Addresses are printed.
  • the printed images are preferably at a distance from each other on the circumference of the plate cylinder arranged.
  • These printed images are, for example, strip-shaped trained and between adjacent print images there is preferably a space.
  • the transmission segment can be realized particularly easily as a radially projecting area of a rubber blanket.
  • a multi-layer rubber blanket is preferably used here. With the exception of the transmission segment, everything is removed from the outermost layer.
  • the transmission segment thus forms a radially projecting area.
  • the transfer segment is preferably also strip-shaped and dimensioned such that it only works together with a printed image of the plate cylinder. It is also possible to glue only one segment of a rubber band onto the transfer cylinder. A partial underlay under a complete rubber blanket is also conceivable.
  • FIG. 1 shows a printing unit 1 which has an insert 2, which is used interchangeably in a machine frame 18 is.
  • the insertion 2 is exchanged in a known manner For example, by means of a rail system, not shown here.
  • Ink roller 16 On two opposite bearing plates 19, from at least one of which is shown in FIG. 1 an ink roller 16, a plate cylinder 3, a transfer cylinder 4 as well as an impression cylinder 5.
  • These cylinders are each supported with journals 8, 9 and 10 provided. These are known in a manner known per se Cylinders 3, 4 and 5 by means of a gear 12 with each other connected and driven by a motor 13.
  • the plate cylinder 3 has a plurality of strip-shaped on its circumference 3a Print images 7, each of which is an information for form a print image, for example for an address.
  • Print images 7 are arranged at a distance from one another and between adjacent print images a strip-shaped space 20.
  • the printed images 7 are arranged in a row next to each other in the circumferential direction, as Figure 2 clearly shows.
  • the width of the printed images 7 is 1 inch, for example.
  • the width of the spaces 20 is also 1 inch, for example.
  • On a plate cylinder 3 with a circumference of 24 inches can thus 12 such Print images 7 are arranged.
  • the plate cylinder 3 is the same via the gear 12 Speed like the transfer cylinder 4 and the impression cylinder 5 rotated. These cylinders are located here to each other. However, the plate cylinder 3 can additionally still be rotated relative to the transfer cylinder 4.
  • an adjustment drive 11 is provided.
  • the adjustment drive 11 may have a servo motor with which it is relative Rotary movement can be carried out controlled. Conceivable is also turning by means of a planetary gear, not shown here.
  • the plate cylinder 3 can thus run relative to the transfer cylinder 4 can be rotated. But it is also conceivable here an embodiment in which the plate cylinder 3 for turning is moved away from the transfer cylinder 4. After twisting the plate cylinder 3 is again shown in FIG Working position shifted.
  • the transfer cylinder 4 is preferably, for example, a blanket cylinder and has a preferably strip-shaped transfer segment 6 on its circumference. According to FIG. 5, this transmission segment 6 protrudes radially. It forms an area of a rubber blanket 17 which is applied in a known manner and preferably covers the entire outer surface of the transfer cylinder 4.
  • the rubber blanket 17 is preferably multilayered according to FIG. 5. With the exception of the transmission segment 6, the outermost layer has been removed.
  • the transmission segment 6 can also be implemented in another way. For example, it can be a piece of rubber blanket that is applied to the transfer cylinder 4. Such a segment 6 can, for example, be glued on or held magnetically.
  • An embodiment is also conceivable in which a corresponding area of a rubber blanket is displaced radially outward, for example with a plunger, not shown here. A partial pad between the cylinder and the rubber blanket is also conceivable.
  • the transmission segment 6 is dimensioned and arranged that it only works with one of the printed images 7.
  • the transmission segment works 6 together with the printed image 7a. While printing the information of the printed image 7a on the Transfer segment.
  • the other print images 7b, 7c and 7d never come into contact with the transfer segment during printing 6 and are therefore not effective.
  • the information of the printed image 7b is printed, so the plate cylinder 3 by means of servo drive 11th in Figure 3 rotated clockwise so that the printed image 7b 4 cooperates with the transmission segment 6.
  • the printed image 7b now comes with each revolution in contact with the transmission segment 6 and accordingly the information of the printed image 7b on a paper web 15 or other suitable substrate printed.
  • the paper web 15 runs according to Figure 1 in the direction of arrow 14 between the transfer cylinder 4 and the impression cylinder 5 therethrough.
  • Impression cylinders 5 are well known to the person skilled in the art.
  • impression cylinder 5 can also be a rubber cylinder.
  • the printed image 7b can be printed on the printed image 7c in the same way or be changed to the printed image 7d.
  • the plate cylinder accordingly 3 changed directly from printed image 7a to printed image 7d or 7c become.
  • twisting in reverse direction possible The twisting is preferably done then when the transmission segment 6 according to Figure 1 outside of the contact area. In this case it is a Moving possible without great friction.
  • Such one relative twisting is done in a simple manner by means of the Planetary gear possible. Suitable planetary gears are well known to the expert and therefore do not have to be here are explained in more detail.
