Definitions

  • the invention relates to a device for shredding value documents, e.g. Banknotes, checks, tickets, vouchers etc.
  • Value documents that are no longer fit for circulation are known to be sorted out and destroyed.
  • used banknotes z. B. by commercial banks, transport companies, etc., checked by means of banknote processing machines and sorted by their fitness for circulation. Notes that are so heavily soiled or damaged that they should not be re-circulated are destroyed, e.g. shredded. Also, in the quality inspection of new banknotes immediately after their production faulty banknotes are sorted out and shredded.
  • the shredding of banknotes is eg from the EP0565112 B1 known.
  • Known shredding devices have two rotatably mounted cutting devices, which rotate in opposite directions, and engage with their cutting edges.
  • the banknotes to be shredded are successively drawn one after the other between the two cutting devices and thereby cut by the cutting edges into small chips, which are torn along. These chips are removed by a scraper from the cutting edges and fall down or are sucked.
  • Another shredding device comprising scraper is off WO2004014559 known.
  • the shredding device is designed for shredding documents of value and has at least two counter-rotatable cylindrical cutting devices, which lie opposite one another with respect to a transport path of the value documents to be shredded.
  • the value documents to be shredded are transported one after the other along their transport path between the two cutting devices in order to shred them.
  • the two cutting devices each have a plurality of cutting edges, which mutually interlock at the facing front sides of the two cutting devices to cut the transported along the transport path value documents using the cutting edges in a variety of Werturgischnipsel.
  • the cutting device has, for example, a multiplicity of cutting disks, which have a circular outer contour have, wherein the cutting edges of the cutting device lie on the outside of the cutting discs and extend along the circumference.
  • the cutting devices are each assigned a scraper having a plurality of mutually parallel scraper elements, which are arranged so that the stripping between the cutting edges of the respective cutting device to remove the Werturgischnipsel of the cutting edges, in particular located between the cutting edges Werturgischnipsel.
  • the shape of the stripping elements is selected such that the stripping elements do not engage between the cutting edges of the respective cutting device at the front side of the respective cutting device facing the transport path of the value documents, but in particular not at the rear side of the respective cutting device facing away from the transport path of the value documents between the cutting edges of the respective cutting device to grab. This ensures that - viewed in the direction of rotation - after the scraper enough space for non-stripped Wert collectionschnipsel is created, which are pulled between the scraper and the cutter.
  • the side of the roller-shaped cutting device which faces the transport path of the value documents is designated as the front side of the respective cylindrical cutting device.
  • the rear side of the roller-shaped cutting device is correspondingly that side of the cylindrical cutting device which is remote from the transport path of the value documents.
  • the underside of the cutting device is the side of the cutting device at which the Wertzanipsel leave the cutter.
  • the scraper surrounds the respective cutting device preferably only at the front and bottom of the cutting device, but not at the back of the cutting device.
  • the lowest angular position of the respective cutting device is that azimuthal angular position of the cutting device (ie with respect to the axis of rotation of the cutting device), which, viewed along the direction of rotation of the cutting device, is 90 ° to the connecting line of the axes of the two cutting devices (ie the center of the underside of the cutter).
  • the stripping elements are stationary, i. they are not moved relative to the cutter.
  • the stripping elements are not mounted on the axis of the cutting device, but in an existing outside the cutter recording.
  • the attachment in an existing outside of the cutting device recording is advantageous because the shredder device is thereby easier to disassemble into its components scraper and cutter, e.g. to remove stuck value document snippets.
  • the stripping elements protrude from the outside between the cutting edges of the respective cutting device.
  • the wiping elements overlap the outer contour in a (circular arc) section which extends over an azimuthal angle section of the cutting device.
  • the overlapping angle section in which the stripping elements overlap with the outer contour of the respective cutting device, does not reach the document shredded documents until after the cutting process.
  • the shape of the stripping elements is selected such that the overlapping angle section in which the stripping elements and the outer contour of the cutting device overlap extends over at most 50 °, preferably at most 40 °, particularly preferably at most 25 °.
  • the arc length of the overlap area along the outer contour of the cutting device is preferably at most 40 mm, more preferably at most 20 mm.
  • the fact that the overlapping angle section is so short is achieved that as little as possible Werturgischnipsel hang in the space between the stripping and the cutting device.
  • the azimuthal position of the overlapping angle section (azimuthally, ie with respect to the axis of rotation of the cutting device), in which the stripping elements overlap with the outer contour of the respective cutting device, is in an angular range between 20 ° and 100 °, viewed along the direction of rotation of the cutting device. in particular between 20 ° and 80 °, after the line connecting the two cylindrical cutting devices.
  • the radial distance of the wiper elements from the surface of the cutter is at least 10 mm. This ensures that there is free space on the underside of the respective cutting device, between the cutting device and the wiper, in which unstripped Wert collectionschnipsel that have been pulled through between the wiper and the cutter, find space. This Wert collectionschnipsel can be transported away from the free space down, in particular be sucked.
  • the shape of the scraper elements is selected so that the distance between the scraper elements and the surface of the cutting device increases continuously from the overlapping angle section along the direction of rotation of the cutting device. Since the available space for unstripped Wert collectionschnipsel continues to increase after the scraper, a congestion of Wert collectionschnipsel is prevented and so facilitates the removal / suction of unstripped Wert collectionschnipsel.
  • the stripping elements essentially have the shape of two angle legs which enclose an internal angle which is between 110 ° and 160 °.
  • two mutually adjacent stripping elements of the cutting device are separated from each other by a spacer, which rests flat against the two adjacent stripping and (at least where it is located) fills the space between the two stripping.
  • the spacer elements are arranged outside the respective cutting device.
  • the side of the spacer elements facing the respective cutting device runs parallel to the outer contour of the cutting device.
  • the spacer elements have on their side facing the respective cutting device the smallest possible distance from the surface of the cutting device.
  • the radial distance of the stripping of the outer contour of the respective cutting device is at most 1 mm. This small distance avoids that Wert collectionschnipsel be pulled between the scraper and the cutter.
  • the shape and attachment of the stripping elements is designed so that there is a free space on the rear side of the respective cutting device in the radial direction of the cylindrical cutting device.
  • the free space is preferably in the lower region of the rear side of the respective cutting device.
  • the clearance is, for example, in an (azimuthal) angular range between 90 ° and 180 ° to the line connecting the two cylindrical cutting devices.
