Definitions

  • the invention relates to a dispensing device for sheet material, in particular a value dispenser, comprising a storage container for a stack of sheets and a removal and separating device assigned to the storage container with at least one removal roller intended for bearing against the sheet stack, a plurality of transport rollers arranged next to one another with axial spacing and associated with them Counter rollers, which are radially adjustable with respect to the transport rollers and axially offset such that they can each dip between two adjacent transport rollers, the rollers arranged on mutually parallel shafts being drivable in the same direction and the counter rollers and at least one transport roller being made of hard material, while the other transport rollers are made of an elastically resilient material.
  • a device of the type mentioned above is known for example from DE-PS 28 50 185.
  • dispensing devices of this type there is generally the problem of ensuring reliable separation of the sheets.
  • this presents no particular difficulties, provided that one is dealing with a predetermined, constant sheet quality.
  • this requirement is not met, for example, when separating banknotes in two ways.
  • the paper qualities used in the individual currencies differ considerably from one another, on the other hand, the quality of the banknotes changes with their use. New banknotes are generally relatively smooth and stiff, while with use they become rougher and flatter at the same time.
  • dispensers of the type mentioned at the outset should be suitable for all types of banknotes without changing roles.
  • An output device of the type mentioned is also known from GB-A-231 499.
  • the running surfaces of the transport rollers are each wrapped in a rubber band or provided with a rubber coating. Although this increases the grip of the rollers, a reliable separation of the leaves cannot be ensured.
  • a transport roller for transporting paper and office machines which consists of a hard material, and in its tread has an annular groove.
  • a ring made of elastic material is inserted into this ring groove, which protrudes radially beyond the running surface or peripheral surface of the roller.
  • the invention has for its object to further improve an output device of the type mentioned, so that a reliable separation of the sheets is guaranteed even with extremely different paper qualities.
  • the conveying of the sheets entering the nip is carried out primarily by the an elastic, resilient material existing transport rollers.
  • it is precisely these rolls which tend to avoid the counterpressure of the counter-rotating rolls required for the separation, so that sheets or banknotes of certain paper quality repeatedly result in a pack of several sheets simultaneously winding through the nip.
  • This possibility is eliminated by the solution according to the invention, since the soft material with a high coefficient of friction and thus a high entrainment effect is arranged directly in the surface of the hard transport rollers.
  • the height of the radial protrusion of the annular strip over the surface of the hard transport rollers is to a certain extent depend on the type of soft material used, however, a radial projection of approx. 0.1 to 0.2 mm has proven to be expedient.
  • the elastically deformable material of the annular strips should have a Shore hardness of approx. 75.
  • a suitable material is, for example, a polyurethane elastomer sold under the trademark Vulkollan.
  • the hard transport rollers can be made of metal and have a circumferential groove in which the annular strip is inserted.
  • FIG. 1 shows a separating module, generally designated 10, which consists of a cuboid frame into which a cassette 14 containing a sheet stack 12 is inserted.
  • a flap 16 of the cassette 14 is opened, so that pull-off rollers 18 of a pull-off device of the separating module 10 on the foremost sheet in the cassette 14 contained stack 12 abut.
  • the stack 12 is biased by a device, not shown, in the direction of the take-off rollers 18, so that the sheets of the stack 12 are constantly in contact with the take-off rollers 18 with a certain pretension.
  • the take-off rollers 18 are arranged on a shaft 20 which can be driven in the direction of arrow B via a drive device 10, not shown.
  • the take-off rollers 18 convey the sheet of the stack 12 resting against them or, if appropriate, also a plurality of sheets adhering to one another in the direction of a nip between transport rollers 22 and counter-running rollers 24, which are arranged on shafts 26 and 28 parallel to the shaft 20 and in the same direction as the Take-off rollers 18 can be driven counterclockwise.
  • the transport rollers 22 have the task of conveying the sheet lying against them upwards through the nip in FIG. 1, while the counter-rollers are intended to prevent more than one sheet from passing through the nip between the transport rollers 22 and the counter-rollers 24.
  • the counter-rollers 24 can be either in drive connection with the transport rollers or with the take-off rollers 18
  • the transport rollers 22 are combined in three groups, the transport rollers 22 of each group being connected to one another in one piece.
  • the counter-running rollers 24 are combined in three groups of rollers which are integrally connected to one another.
  • the counter-rollers 24 are axially offset relative to the transport rollers 22 in such a way that they lie opposite the gaps between the transport rollers 22.
  • the shaft of the counter rollers 24 is mounted in rockers 30 so that the counter-rollers 24 can dip into the spaces between the transport rollers 22, as indicated by the dash-dotted lines.
  • the fingers 32 of a guide plate 34 which is pivotably supported by a shaft 36 in the side walls 38 of the separating module 10, also engage in the spaces between the transport rollers 22.
  • the two outer groups of transport rollers 22 of the 3 roller groups shown in FIG. 2 each consist of metal, for example aluminum, and are provided with a circumferential annular groove 40 which is narrower than the respective peripheral surface 42 of the transport rollers 22 (FIG. 3).
  • This material with a Shore hardness of approximately 75 has a high coefficient of friction and thus ensures active transport of the sheets that enter the gap between the transport rollers 22 and the counter-rollers 24.
  • the middle group of transport rollers consists of an elastically resilient material, preferably having a cellular or porous surface, e.g. made of cellular polyurethane with a material density of 0.75 g / cm3.
  • each roller group are in one piece with one another, so that they form a transport roller with a comb-like profile.
  • each of these rollers could also consist of individual transport rollers with intermediate rings or of stepped ones individual transport rollers.
  • the distance between the transport rollers 22 and the counter-rollers 24, ie the width of the nip, is adjusted according to the thickness and quality of the sheets to be removed.
  • the setting is made by pivoting the shaft 28 of the counter roller 24 mounted in the rockers 30.
  • a suitable adjustment mechanism is described in DE-PS 28 50 185. The nip is adjusted so that only one sheet can pass at a time.
  • the hard transport rollers have a continuously hard, smooth circumferential surface, there is the possibility in this case that the simultaneous passage of several sheets through the nip is prevented, but that the frictional forces exerted by the transport rollers on the sheet facing them are also insufficient to overcome the static friction between the adjacent sheets and to convey this single sheet through the nip, since the driving forces exerted on the sheets by the transport rollers made of soft material are limited due to the flexibility of the material.
