Definitions

• bank notes For the separation of sheet material, in particular bank notes, arrangements have become known which have a mechanical separation device and a mechanical retention device.
• the arrangements are used, for example, in banknote processing machines to pull off a single banknote from a stack of banknotes in order to process them in the banknote processing machine, ie. H. to check, sort, etc. the bank note.
• the separating device detects one bank note each, whereas the retaining device holds back further bank notes of the stack, so that only a single bank note is separated in each case.
• the separating device and the retaining device are at a defined distance from one another.
• This distance is also called the separating gap and corresponds approximately to the thickness of the banknotes to be separated.
• an adjusting device is provided for setting the separating gap, with which the width of the separating gap can be changed.
• the known adjusting device has an eccentric shaft with which the distance between the retaining device and the separating device can be changed in order to adjust the width of the separating gap.
• the eccentric shaft is formed by a cylindrical shaft that is mounted eccentrically.
• the known arrangement for separating sheet material thus has the disadvantage that the setting of the separating gap to the sheet material to be separated in each case can be very difficult, since the adjustment of the adjusting device or the eccentric shaft by a certain angle does not correspond to a certain, constant one or intuitively predictable change in the width of the separating gap.
• the invention is based on the consideration that an arrangement for the separation of sheet material, in particular banknotes, with a mechanical separation device and a mechanical retention device and an adjustment device for setting a separation gap that results between the separation device and the retention device Fixed or intuitively ascertainable correlation when setting the singling gap results when the adjusting device has an adjusting means with a cam-shaped profile.
• the invention thus has in particular the advantage that the setting of the separating gap is particularly easy and can be carried out well, since, due to the cam-shaped setting means, there is a fixedly predetermined or intuitively ascertainable connection when setting the separating gap, so that the setting can be made regardless of the position of the adjusting device or the setting means.
• Figure 1 is a schematic representation of a basic structure of an arrangement for separating sheet material
• FIG. 2 shows a detailed view of a component of the arrangement for separating sheet material according to FIG. 1.
• FIG. 1 shows a schematic representation of a basic structure of an arrangement 20 for separating sheet material.
• the arrangement 20 is a mechanical separating device 40, for example a driven roller with circumferentially arranged sections of higher and lower friction, a retaining device 41, the z. B. can also be formed by a roller, and an adjusting device 30 to 36, for the adjustment of one between. Separating device 40 and retaining device 41 resulting in individual gap 42.
• a mechanical separating device 40 for example a driven roller with circumferentially arranged sections of higher and lower friction
• a retaining device 41, the z. B. can also be formed by a roller, and an adjusting device 30 to 36, for the adjustment of one between. Separating device 40 and retaining device 41 resulting in individual gap 42.
• the banknotes are stored in a stack on a tray 50.
• the lowest banknote in each case is detected by the separating device 40 and the stack of banknotes is moved into the area between the separating device 40 and the retaining device 41.
• a feed device 37 for example a guide plate, can additionally be provided for the secure guidance of the banknotes in the stack. If the section of the separating device 40 with higher friction reaches the area between the separating device 40 and the retaining device 41, the lowest bank note in contact with the separating device 40 is transported through the separating gap 42 and transferred to a transport system 51 which transports the bank note for further processing.
• the retaining device 41 is designed such that it exerts a force on the banknotes which is greater than the force of the separating device 40 in the lower friction section, but less than the force of the separating device 40 in the higher friction section. This can be achieved, for example, by selecting a material for the retaining device 41 with a friction that lies between the lower and the higher friction of the separating device 40.
• the desired restraining effect can also be achieved by a suitable geometric design.
• the retention device 41 can have a friction which corresponds to the higher friction of the separating device 40.
• the geometric design then provides a larger area in the section of the higher friction of the separating device 40 than with the retaining device 41, so that the separating device 40 exerts a greater force than the retaining device 41 with the same friction, as a result of which the contacting device 41 is in contact Banknote is isolated.
• the separating device 40 and the retaining device 41 are designed as rollers, each of which has alternating elevations and depressions, the separating device 40 and the retaining device 41 being arranged such that an increase in one device to one depression is provided the other facility. If the separating gap 42 between the separating device 40 and the retaining device 41 is set slightly smaller than the thickness of the bank notes to be separated, the bank note to be separated is deformed in a wave shape and the catenary of the adjoining increases of the separating device 40 and the retaining device 40 cause the separation or retention of the paper money.
• the adjusting device 30 to 36 has a lever 31 which is connected via a detent 32, 33 with an adjusting means 30.
• the setting means 30 can be designed in a wave shape and has a cam-shaped profile.
• the cam-shaped profile of the adjusting means 30 rests on a holder 35 which is rotatably mounted about an axis 36.
• the axis 35 is fastened, for example, in a housing accommodating the arrangement 20 for the separation of sheet material.
• the retaining device 41 is also mounted in the holder 35.
• a force 38 which is generated, for example, by a spring, which is also fastened in the housing, acts against the holder 35 and presses it against the adjusting means 30 or its cam-shaped profile.
• the width of the separating gap 42 can be adjusted, since the separating device 40 is fastened in the housing and is thus fixed in relation to the retaining device 41.
• the detent 32, 33 of the lever has fixed predetermined detents 34 which, for. B. can be 15 °.
• the catch 32, 33 serves to facilitate the setting, but in principle the catch 32, 33 can also be dispensed with.
• FIG. 2 shows a detailed view of the setting means 30 of the arrangement 20 for separating sheet material according to FIG. 1.
• FIG. 2 shows the cam-shaped profile of the setting means 30, as well as a profile of an eccentrically mounted shaft 60 for comparison, with a profile of a shaft 61 mounted centrally thereon.
• an adjustment range of 180 ° is shown as an example, which is the same in twelve large areas 1 to 12 is divided, which correspond to the detents 34 of the detent 32, 33 described above.
• the lever 31 By adjusting the lever 31, the setting range of 180 ° can be covered, whereby the desired setting position of the width of the separating gap 42, which should correspond approximately to the thickness of the banknotes to be separated, can be achieved.
• the choice of the cam-shaped profile of the setting means 30 ensures that there is a uniform change in the separating gap 42 over the entire setting range of 180 °, i. H. each detent 1 to 12 causes the same change in the width of the separating gap 42.
• the cam-shaped profile can also be set in such a way that the course of the change over the setting range is intuitively easy to understand.
• a progressive course can be provided, in which the amount of change increases, e.g. B. an exponential curve.
• a degressive course can be provided, in which the amount of change decreases, e.g. B. reversely exponential course.
• a suitable other shape can be chosen, e.g. B. a skid-shaped restraint. It is also possible, instead of the change in the width of the separating gap 42 described above, to adjust the position of the separating device 40 by adjusting the position of the retaining device 41. In addition, it can be provided that both the position of the retaining device 41 and the position of the separating device 40 are changed.
• the arrangement according to the invention for the separation of. Sheets are particularly suitable for use in banknote processing machines which are used for counting, checking, evaluating, sorting, destroying, etc. banknotes.
• the use of the arrangement according to the invention ensures that only individual bank notes are transferred to the transport system of the bank note processing machine, which improves the overall function of the bank note processing machine.
• the banknote processing machine can also be designed to automatically accept banknotes of a deposit.
