Definitions

  • the invention relates to an apparatus and a method for printing on objects, in particular cylindrical objects, in particular with a high-pressure process such as the flexographic printing process.
  • This printing method has the advantage that the print quality is relatively independent of small variations in the distance between the screen printing fabric and the object to be printed, since the ink is pressed with a doctor blade through the flexible screen printing fabric on the object to be printed.
  • the screen printing method also has disadvantages compared with other known printing techniques. For example, it is possible to print finer structures with high-pressure processes, such as the flexographic printing process, which is particularly advantageous when images are to be printed with high resolution-possibly even multicolored.
  • the print quality is sensitive to accurate alignment of the printing cylinder with respect to the item to be printed.
  • the distance between the printing cylinder and the object must be kept as constant as possible over the entire area to be printed.
  • Already deviations of 0.01 - 0.02 mm lead to the fact that the quality of the printed image decreases strongly.
  • the object is often completely or partially closed on one side, for example glasses, bottles made of plastic or glass or tubes for cosmetics, which are printed before filling and closing and therefore a substantially cylindrical shape to have.
  • Cylindrical objects For example, can be pushed onto a mandrel and held by this, for example, by a radial expansion of the mandrel.
  • a receiving or expanding mandrel is in the German utility model DE 20 2004 019 382 U1 described.
  • holding device of the object to be printed is held by the generation of negative pressure within the holding device on this. It is also often mechanical clamping devices are used, which are placed on the cylindrical object and so hold the object during the printing process.
  • the holding device is mounted on one side. A storage on the opposite side is not possible because there the recorded object is often (partially) closed.
  • holding devices can be converted in order to adapt them to the respective print job.
  • due to unavoidable manufacturing tolerances often can not be ensured that the position of the components of the holding device after the conversion exactly matches the position before the conversion.
  • print quality degradation may be a varying wall thickness of the articles to be printed, whereby the distance of the printing cylinder to the surface of the article either during printing of an object or between the printing operations on different objects varies.
  • the object to be printed is held on one side on a spindle. Again, an adjustment of the position of the printed image with respect to the circumferential direction of the article is possible.
  • An article printing apparatus comprises a printing unit having a printing unit mounted on a support unit.
  • the printing unit has at least one anilox roller for picking up the ink and a printing cylinder to which the ink is at least partially transferred from the anilox roller.

  • a printing plate or sleeve may be attached according to the printing method with which the device of the invention is to be used, for example a planographic printing plate (for example for offset printing) or a high-pressure plate (for example for flexographic printing).
  • a device further comprises a holding device, from which an object to be printed, such as a glass, a bottle or a tube can be received.
  • the holding device is a receiving mandrel having an outer diameter which is only slightly smaller than the inner diameter of the articles to be printed. An object to be printed can then be easily pushed onto the arbor.
  • One possible embodiment of the holding device provides that compressed air is conducted into the receiving mandrel, whereby elastic elements in the interior of the receiving mandrel expand and metal strips which form the surface of the receiving mandrel press outward. Characterized the object to be printed is held firmly on the mandrel and can be rotated by a rotation of the mandrel about its own longitudinal axis, so that the object are printed circumferentially with the pressure plate mounted on the printing plate.
  • holding device of the object to be printed is held by the generation of negative pressure within the holding device on this.
  • Another embodiment uses mechanical clamping device.
  • the holding device can also be adapted to the inner shape of the object to be printed.
  • a device according to the invention further comprises a measuring device with which the surface of an object received by the holding device can be measured.
  • a measuring device with which the surface of an object received by the holding device can be measured.
  • the surveying device is mounted in a known orientation to a main body of the device according to the invention and can be a measurement of the surface of a received by the holding device object or the surface of the holding device at one or more points either fixed holding device or during rotation of the holding device to a Perform axis.

  • rotary transfer machines are used in printing cylindrical objects when several steps are required during printing.
  • Work steps can be, for example, printing with one color in each case in order to obtain a multicolored imprint on the object as a result.
  • Another possible operation is, for example, pre-treating the surface of the article to be printed in order to improve the adhesion of the colors on the surface.
  • Such a process is known under the name UVitro and is described in the European patent EP 1 148 036 B1 described.
  • treating the article before or after printing with a varnish is possible.
  • the measurement of the surface of an object to be printed picked up by a holding device is now also provided as a working step on a rotary indexing machine.
  • the measuring device Since the measurement of the surface can not take place simultaneously at the point that is being printed, the measuring device must be arranged offset to the printing unit.
  • the measuring device can be arranged relative to the printing unit with respect to the holding device.
  • the measuring device is therefore advantageous to arrange the measuring device on an otherwise free workstation of the rotary transfer machine, so that an object to be printed or the holding device can be measured at this workstation with a full rotation of the holding device, while at the workstation with the first printing unit nor a previous object is printed.
