Definitions

• the invention relates to an output device for sheet material according to the preamble of claim 1_
• an output device for sheet material in particular bank notes, comprising a storage container for a sheet stack and a deduction and separating device assigned to the storage container with at least two intended for contact with the sheet of the sheet stack to be removed take-off rollers arranged at an axial distance from one another.
• the take-off rollers are rigidly connected to a take-off shaft arranged in fixed bearings, which can be driven via a clutch.
• the sheets are pressed against the take-off rollers by a pressure slide in the storage container.
• stacks of banknotes are not of the same thickness over the entire stacking area.
• a trigger device of the type specified in the preamble of claim 1 is known from DE-AS-18 08 272.
• the arrangement of the take-off rollers on the hollow shaft, which is movable in all directions, is intended to achieve a uniform transmission of the pull-off forces to the first sheet of the stack to be removed.
• the fact that the end face of the stack does the reasons mentioned above is not always exactly flat, so that one of the pull-off rollers comes into contact with the stack before the other and a braking torque is exerted on this roller.
• the hollow shaft is not only adjusted parallel to the stack surface. Rather, it is also set obliquely with respect to the top edge of the sheet. As a result, a skewing moment is exerted on the sheet to be removed.
• lateral sheet guides are therefore provided in the take-off device according to DE-AS-18 08 272.
• the invention is based on the object of designing an output device of the type specified in the preamble of claim 1 in such a way that a straight take-off of the individual sheets ensures the same even without lateral guides.
• FIG. 1 shows a schematic partial side view of a storage container for banknotes and the essential elements of a deduction and separating device
• FIG. 2 shows a section through the pendulum shaft with the drive shaft containing the axis in a side view
• FIG. 4 shows a schematic plan view of a groove of the bearing ball of the universal joint and of a web on the pendulum shaft which plunges into it.
• FIG. 1 shows a part of 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 is opened so that take-off rollers 18 of a take-off device of the separating module 10 rest against the foremost sheet of the stack 12 contained in the cassette.
• the stack 12 is pretensioned in the direction of the take-off rollers 18 by a pressure device, not shown, so that the sheets of the stack 12 are always with it a certain pre-tension on the take-off rollers 18.
• the take-off rollers 18 are arranged in a manner which will be explained in more detail later on a drive shaft 20 which is rotatably mounted in bearings 21 fixed to the frame and which is connected to the driven side of a magnetic coupling (not shown) and can be driven in the direction of arrow B.
• the take-off rollers convey the sheet 22 of the stack 12 lying against them or, if appropriate, also a plurality of sheets 22, 24 adhering to one another in the direction of a nip between transport rollers 26 and counter-rollers 28, which run on shafts 30 parallel to the drive shaft 20. 32 are arranged and can be driven in the same direction with the take-off rollers 18 in the direction of arrow B.
• the shaft 30 is connected to a pulley 34 and connected to the drive side of the magnetic coupling via a belt 36, so that the transport rollers 26 are driven permanently.
• the transport rollers 26 have the task of conveying the sheet 22 lying against them upwards through the nip, while the counter-rollers 28 are intended to prevent more than one sheet from passing through the nip between the transport rollers 26 and the counter-rollers 28.
• the pendulum shaft 42 is mounted on the drive shaft 20 by means of a universal joint, generally designated 48.
• the universal joint comprises a bearing ball 50 which is fixedly connected to the drive shaft 20 and has ring-shaped bearing surfaces 52.
• four axially parallel grooves 54 are formed on the surface of the bearing ball 50 (see also FIG. 3), which have a constant depth over their length.
• spherical-shell-shaped bearing surfaces 56 are formed in the pendulum shaft. Bores 58 extend from the bearing surfaces 56 to both ends of the pendulum shaft 42, the diameter of which widens conically towards the free ends of the pendulum shaft 42, so that the pendulum shaft 42 moves out of its central position parallel to the axis 60 of the drive shaft 20 after each any side can be pivoted by the angle ⁇ ⁇ / 2.
• a torque transmission from the drive shaft 20 to the rocking shaft 42 to pivot while maintaining the encryption to enable the same, are in the 'Be ⁇ area of the central drawing roller at the inner side of the rocking shaft 42 bridges 62 are provided, which engage in the grooves 54 in the bearing ball 50 , as shown in Figure 3. It also follows that, despite the torque transmission about the axis 60, the pendulum shaft 42 can pivot about an axis 64 perpendicular to the plane of the drawing.
• the webs 62 - viewed in a plan view of the grooves 54 (FIG. 4) - are designed in the form of a biconvex lens, so that they can each perform a pivoting movement about an axis 66 directed perpendicular to the plane of the drawing in FIG .
• the axes 60, 64 and 66 are mutually perpendicular to one another and thus form the axis system of the universal joint 48.
• the pendulum shaft 42 Since for a uniform distribution of the pull-off forces only a pivoting movement of the pendulum shaft 42 perpendicular to the plane of the sheet 22 to be pulled, i.e. perpendicular to the end face of the stack, the pendulum shaft 42 has at its right end in FIG. 2 a guide shoulder 68 which engages between the two legs 70 of a guide fork 72 (FIG. 1) which causes the pendulum shaft 42 to tilt is prevented about an axis perpendicular to the end face of the stack and only allows the pendulum shaft 42 to oscillate about an axis parallel to the end face of the stack.
• the guide fork 72 is fastened to a support 74 which is rigidly connected to the frame of the separating module 10 and which is indicated schematically in FIG.
