Definitions

  • the invention relates to a device for cutting a bundle provided with a band according to the preamble of claim 1.
  • a device of the type mentioned above is known for example from EP 0 100 990 B1.
  • This device comprises a cutting device which is arranged parallel to the plane of the leaves of a bundle.
  • the knife of the cutting device is partially immersed in the bundle between two sheets, whereby it comes into contact with the banderole due to a relative movement between the cutting device and the bundle.
  • the band is cut by the knife. Since the knife rotates through the bundle between two blades, there is basically a risk that blades with kinks, folds or corrugations can be damaged by the knife.
  • the rotary knife is mounted axially displaceable, so that it can possibly avoid the bumps present in the bundle.
  • the invention has for its object to provide a device for cutting a bundle of sheets, which allows cutting the banderole without damaging the sheets with a trouble-free process.
  • the basic idea of the invention is to propose a device for severing a bundle, which, in addition to the cutting means provided for severing the bundle of the bundle, has an element for spreading the bundle, which, like the cutting means, has on an abutting edge of the bundle between two sheets of the bundle at least partially immersed therein, the sheets being guided past the cutting means during a relative movement caused between the device and the bundle by the expansion element.
  • the spreading element ensures that the blades are guided past the cutting means despite any bumps that may be present in the bundle, without causing cuts, i.e. Damage to the blades or jamming of the knife.
  • the bundle is preferably transported and guided past the correspondingly positioned device, but the device can also be moved along a correspondingly positioned bundle.
  • the cutting means can be designed, for example, in the form of a rotating rotary knife which is arranged axially on an axis driven by a motor at the same height as the spreading element.
  • the spreading element can, for example, be a finger-shaped sheet which is arranged, for example, on the housing or axially on a motor axis of the device. The expanding knife relieves the rotating knife in the axial direction when it is immersed in the bundle.
  • the motor output does not have any appreciable frictional work reduced between the sheets and the knife, but is only available in the device according to the invention for severing the banderole. Due to the lower load, the service life can also be increased.
  • the device according to the invention can preferably be used for debandering bundles of freshly printed banknotes or also used banknotes.
  • Fig. 1 shows a first embodiment of the device for cutting a bundle in a plan.
  • the bundle 1 comprises several, for example 100, substantially flat sheets, for example banknotes, around which one closed band 2 is guided.
  • a device is provided which comprises a cutting means 10 and an element 20 for spreading the bundle 1.
  • the cutting means 10 can be designed, for example, in the form of a rotary knife, which is arranged axially on an axis 18 which is driven by a motor, so that the rotary knife rotates.
  • a rotary knife is described in detail in EP 0 100 990 B1, for example, so that it is not dealt with in more detail here.
  • the element 20 for spreading the bundle 1 can, for example, in the form of a finger-shaped sheet, which e.g. has a thickness of approximately 1 mm to 3 mm, be carried out and is referred to below as "spreading finger".
  • the spreading finger 20 has e.g. a tip 21 projecting beyond the cutting point 15 of the cutting means 10 into the area of the band 2 into the bundle 1.
  • the tip 21 is designed so that it is made as thin as possible, but not too pointed, in order to prevent the leaves from piercing through the tip 21 when the spreading finger 20 is immersed between two sheets of the bundle 1.
  • the spreading finger 20 is arranged on the side 24 facing the cutting means 10 at a distance d from the cutting edge 11 of the cutting means at the same height as this.
  • the distance d forms a gap for the inlet of the band 2 to be cut.
  • Means 13 and 14 are provided for guiding the bundle, which ensure that the band is guided into the gap d provided for the inlet, the band then passing through a relative movement effected at the cutting point 15 between the device and the bundle comes into contact with the cutting edge 11 of the cutting means 10.
  • the spreading element performs the same movement as the cutting means 10 with respect to the bundle, the bundle is spread out by the spreading element so that the sheets are guided past the cutting means at a distance predetermined by the thickness of the spreading element, so that the cutting edge 11 of the cutting means only comes into contact with the band 2 running on the abutting edge 3 of the bundle 1 . As the movement progresses, it is then severed without the blades being able to come into contact with the cutting edge of the cutting means.
  • the dimensions of the spreading element 20 are chosen in such a way that this spreads the bundle 1 in the immediate vicinity of the cutting point 15 at the spreading point 25.
  • the gap d provided for the entry of the band is determined by the distance between the guide means 13 and 14, d. H. by the distance of the cutting point 15 from the spreading point 25.
  • the immersion depth 12 of the cutting means 10 as well as that of the expansion element 20 in the bundle is determined by the distance of the guide means 13 and 14 from the axis 18 and can be selected accordingly for the expansion element and the cutting means depending on the desired immersion depth.
  • the immersion depth 12 is preferably such that the expansion element 20 is almost completely immersed in the bundle, but the cutting means 10 is only partially, e.g. 2 to 6 mm deep, immersed.
  • the area of action of the cutting means between the sheets in the bundle is thus only kept as large as is necessary for cutting through the banderole.
  • the knife can rotate opposite to the direction of movement or in the direction of movement.
  • Fig. 2 shows the device shown in Fig. 1 in a front view without bundles.
  • the device comprises, for example, a housing 16 which is provided with an opening in which a motor 17 with an axis 18 is arranged.
  • a carrier 19 is provided for receiving the cutting means 10.
  • the cutting means is arranged at the same height as the expansion element 20 and is therefore covered by the expansion element 20 in the front view.
  • the expansion element 20 is fastened to the guide means 13.
  • the guide means 13 and the guide means 14 are in turn attached to the housing 16.
  • FIGS. 3 and 4 each show a top view of further exemplary embodiments of a device for cutting a bundle, which differ from the embodiment shown in FIGS. 1 and 2 only with regard to the design of the element 20 for spreading.
  • the bundle cannot be guided along the guide means 13 and 14 so precisely, e.g. due to poorly sliding sheets, it is advantageous to slightly increase the gap d provided for the entry of the band, as shown in FIG. 3. This prevents the banderole 2 from getting caught on the spreading finger 20 before the cutting point 15.
  • the tip 21 of the spreading finger 20 protrudes further beyond the cutting point 15, the area 22 after the tip 21 being made thinner up to the cutting point 15. This serves to avoid jamming of the expansion element in the bundle during the relative movement in cases in which the banderole lies very tightly around the bundle.
  • the thickness of the spreading element to be selected is therefore primarily dependent on the tightness of the adjacent banderole, but the general aim is to make the spreading element as thick and thus stable as possible, the maximum thickness of the spreading element depending according to the circumstances can be between 1 mm and 3 mm.
  • FIGS. 5 and 6 show a second embodiment of a device for spreading a bundle, which differs from the exemplary embodiments shown in FIGS. 1 to 4 essentially only with regard to the arrangement and the fixing of the spreading element.
  • the spreading element 20 is arranged together with the cutting means 10 on a carrier 19.
  • the expansion element is in this case axially ball-bearing on the axis 18 and arranged at the same height as the cutting means 10.
  • a corresponding fastening 23 is provided, by means of which the spreading element is held in the correct spreading position.
  • the means for guiding the bundle are not shown here.
  • such guide means are also to be provided in this embodiment, so that the bundle can be guided exactly past the device or the device can be guided exactly along the bundle.
  • FIG. 6 shows a top view of the device shown in FIG. 5, the spreading element 20 being in the spreading position and thus in the working position.
  • the fastening 23 prevents the spreading finger 20 from rotating with the axis 18, so that permanent fixing of the spreading finger 20 in the spreading position is ensured.
  • This embodiment has the advantage over the first embodiment that the cutting means 10 and the expansion element 20 are arranged from the outset on a common support 19 at the same height can be, in which case the carrier 19 only has to be fixed accordingly on the axis 18. Subsequent adjustment of the cutting means in relation to the expansion element can be omitted, as may be necessary in the first embodiment if the cutting means is not exactly at the same height as the expansion element attached to the housing. However, this is an important prerequisite to ensure trouble-free operation.
