Definitions

  • the present invention relates to a numbering unit according to the preamble of claim 1. Accordingly, it is a numbering unit with type wheels for applying a character string to a document, wherein the type wheels are rotatably mounted about an axis of rotation, and wherein a type wheel is assigned a rear gripper to to prevent unwanted rotation of the daisy wheel.
  • the invention relates to a rear gripper for a numbering machine according to claim 26 and a numbering machine according to claim 27.

  • the numbering unit can also be referred to as a numbering printing unit or printing unit.
  • known numbering machines are used to apply serial numbers to security documents, in particular to banknotes.
  • a numbering machine is arranged reversibly, i.e. firmly but detachably again if desired, on a retaining ring of a numbering machine (printing press).
  • the numbering mechanism sits on the outside of the retaining ring, and the type wheels of the movement are arranged on the side facing away from the retaining ring.
  • the retaining ring is usually arranged on a numbering shaft of the numbering machine.
  • the numbering units are located on the outside of the retaining ring.
  • the sheet to be printed (in particular a sheet of paper with banknotes to be numbered) is then fed to the numbering machine.
  • the character string applied to the document corresponds to the character string which is predetermined by the types of one of the type wheels arranged next to each other at the moment on the upper side of the numbering unit.
  • a plurality of retaining rings per numbering shaft and a plurality of numbering units per retaining ring are provided, namely distributed over the circumference of the retaining ring. This is known per se and is not the subject of the present invention.
  • the numbering machine can be divided into two and have an upper and a lower part.
  • the lower part can be fixed firmly, but releasably, in particular by means of a clamp on the retaining ring.
  • the lower part of the numbering machine can remain on the retaining ring and only the upper part can be removed and replaced if necessary. This means that the position of the numbering box on the retaining ring remains unchanged and the clamp between the numbering box and the retaining ring does not have to be released.
  • a vertical numbering device applies a character string to the document which extends in the circumferential direction of the retaining ring.
  • a horizontal numbering unit applies a character string to the document, which extends perpendicularly to the circumferential direction of the retaining ring.
  • the numbering machine or the upper part of the numbering machine generally has the daisy wheels and the entire numbering mechanism, which is known per se. These parts must generally be designed so that they can be quickly removed from the retaining ring, in order to avoid misalignment if the numbering mechanism needs to be changed, for example in the event of defects. wear or a change in the print job, not to cause the numbering machine to stand still for too long.
  • numbering machines also have a mechanism that advances the set serial number by one unit at a desired position of the number after each printing process or with each revolution of the mechanism including the retaining ring, so that the next document has a free or empty number. following serial number can be printed.
  • the relevant daisy wheel of the numbering machine is usually rotated by one position. This is known in and of itself.
  • rear grippers are known. These are mounted such that they can be tilted relative to the type wheel and their respective ends engage in suitable recesses in the type wheel in order to prevent the type wheel from rotating.
  • Such a rear gripper generally prevents the type wheel from turning back (to a lower number) completely, due to the creation of a form fit. A certain holding force must be overcome on the other side for the - desired - further turning of the type wheel by the above-mentioned mechanism. If this is reached, the end of the rear gripper close to the type wheel swings away upwards and allows the type wheel to continue turning.
