DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(45) Example embodiments will now be described more fully with reference to the accompanying drawings.
(46) In
(47) Usually, banknotes which are to be paid in are deposited in the input and output compartment as a wad and separated in the upper part of the automated teller machine so that they are supplied one after the other along the transport path 18 via the transfer interface 20 to the safe 10. Further, the banknotes removed from the cassettes 12a to 12d are transported individually one after the other along the transport path 18 via the transfer interface 20 out of the safe 10 and are then stacked to a stack or, respectively, wad with the aid of a known stacking device which is, for example, designed as a stacker wheel. This wad is then output via the input and output compartment. Further, the automated teller machine has a suitable control station and further elements such as a card reader and possibly security devices for the authentication of an operator.
(48) Alternatively, the safe 10 illustrated in
(49) The banknotes are preferably transported along the transport path 18 at a transport speed of 1.2 m per second, preferably 1.4 m per second and removed from the cassettes 12a to 12d at a corresponding speed or, respectively, supplied to these cassettes 12a to 12d at a corresponding speed.
(50) In
(51) In addition to separating and feeding elements of the separating and stacking module 30 elements of the cassette 12a used for the stacking and separating functions are illustrated. As separating elements, the separating and stacking module 30 has three pull-off wheels 32 arranged next to one another, the wheels being spring-mounted on a pull-off wheel shaft 34 and connected to this shaft 34 in a rotationally fixed manner. In the side view shown in
(52) Further, a guiding element 48 is provided which partially encloses the drive wheels 44 and which guides the movement of the banknote 38 around the drive wheels 44. Further, a pressure roller 50 is provided with the aid of which the banknote 38 is pressed against the drive wheels 44 for transport. Further, two stripping rollers 52 are arranged on a shaft 53, which in the present embodiment have a freewheeling mechanism so that they likewise rotate when the drive wheels 44 rotate in the direction of the illustrated arrow P1 even without a rotation of the shaft 53. When the drive wheels 44 are driven in a direction opposite to the arrow P1 illustrated in
(53) In addition, the separating and stacking module 30 has as a feeding element several vane wheels 54 arranged on a drive shaft 62, each of which having two vanes 58, 60 tangentially projecting from a hub 56 of the vane wheel 54. The vanes 58, 60 are connected to the drive shaft 62 in a rotationally fixed manner so that the vane wheels 54 can be driven with the aid of a drive unit via this shaft 62 in the direction of rotation of the illustrated arrow P2. The ends of the vanes 58, 60 are curved opposite to the direction of rotation so that they contact the front side of the stack 36 with their curved outer face upon a rotation in the direction of the arrow P2. In the present embodiment the stack 36 comprises several banknotes having a relatively small first height, of which one banknote forms the front side of the stack 36, and several banknotes having a higher second height, of which one banknote forms the rear side of the stack 36.
(54) The vane wheel 54 is illustrated in
(55) The separating and stacking module 30 further comprises altogether four inclined deflectors 64 which in the present embodiment are pressed with their end facing the stack 36 against the front side of the stack 36 with the aid of a pre-stressed spring 65. By the inclined arrangement of the inclined deflectors 64, the upper area of the banknote 38 is moved towards the front side of the stack 36 upon a contact with the inclined deflector 64.
(56) On the shaft 62, five further upper vane wheels 54 are arranged and connected therewith in a rotationally fixed manner so that the shaft 62 serves as a drive shaft for these altogether six vane wheels 54. A lower vane wheel visible in
(57) The separating and stacking module 30 has a pressure device 45 which contacts a banknote 38 positioned in the feeding area 46 in front of the front side of the stack 36 and presses this banknote 38 against the front side of the stack 36 at least at the contact points. The pressure device 45 is formed such that it contacts the banknote 38 in its lower half when the banknote is positioned in front of the front side of the stack 36. The pressure device 45 can comprise at least one armature of a pull/push magnet designed as a pressure pin or a pressure pin coupled to the armature.
(58) Further, at the bottom of the banknote receiving area of the cassette 12a two cassette vane wheels 72 arranged on a drive shaft 71 are provided which together with belt pulleys for deflecting belts 70 arranged at the bottom of the banknote receiving area of the cassette 12a are connected to the drive shaft 71 in a rotationally fixed manner. Further, on this drive shaft 71 a gear wheel (not illustrated) is arranged which is connected to this drive shaft 71 in a rotationally fixed manner and via which the drive shaft 71 can be driven by a drive unit arranged separately from the cassette 12a when a further gear wheel coupled to the drive unit is engaged with this gear wheel arranged on the drive shaft 71. These gear wheels are engaged when the cassette 12a has been inserted in receptacles provided in the safe 10 and has assumed an operating position for feeding and removing banknotes.
(59) With the aid of the cassette vane wheels 72 and the belts 70 at least a part of the banknote stack 36 contained in the banknote receiving area of the cassette 12a is transported away from the feeding area 46 at least in the lower area of the banknotes of the stack 36 so that supplied banknotes 38 can be pushed into the banknote receiving area of the cassette 12a with the aid of the upper vane wheel 54, with the aid of the inclined deflectors 64 and/or with the aid of the note retracting shutter 68 during the closing operation. After feeding the banknote 38 into the feeding area 46, i.e. when its rear edge is no longer in the area between the drive wheel 44 and the pressure roller 50, the lower vane wheel 66 is rotated so that at least one vane 74, 76, 78 of the lower vane wheel 66 presses the rear edge and/or the lower area of the banknote 38 against the front side of the stack 36. This pressing of the lower area with the aid of the lower vane wheel 66 substantially takes place simultaneously with the movement of the banknote 38 towards the stack 36 caused by the inclined deflector 64.
(60) Further, the separating and stacking module 30 comprises a light barrier arrangement 39 which detects the front edge of a supplied banknote 38 in the area between the drive wheel 44 so that, starting out from the point in time of the arrival of the front edge of the supplied banknote 38 and a preset delay time, the drive of the vane wheel 54 is started via the drive shaft 62. The light barrier arrangement 39 comprises a prism arrangement for a double deflection of a light beam emitted by a light source, the light source and a light sensor for detecting the light beam emitted by the light source being arranged on the same side of the transport path for feeding and removing a banknote 38. The prism arrangement is arranged on the opposite side of the transport path. As a result thereof, in particular a reliable detection is obtained since the light beam intersects the transport path of the banknotes twice. Further, a simple, compact arrangement of the light source and of the light sensor on only one side of the transport path is possible.
(61) Further, the lower vane wheel 66 has been rotated further. Moreover, the separating and stacking module 30 comprises a stripping element 75 to strip off banknotes 38 which might adhere to the surface of the drive wheel 44 and to feed them into the feeding area 46. The stripping element 75 is preferably pressed against a stop by a spring force and is thus kept in the illustrated position.
(62) In
(63) In the feeding position shown in
(64) Further, the lower vane wheel 66 has been rotated further so that the vane 74 of the lower vane wheel 66 approaches the rear edge of the supplied banknote 38 and subsequently presses the rear edge or, respectively, the lower area of the supplied banknote 38 against the stack 36. The vanes 74, 76, 78 tangentially project from a hub of the lower vane wheel 66, preferably at 0, 90 and 180. The vanes 74, 76, 78 of the vane wheel 66 are made of an elastic material, preferably rubber and/or plastic material and are preferably curved in the direction of rotation of the lower vane wheel indicated by the arrow P4. As a result thereof, the vanes 74 to 78, upon a rotation of the lower vane wheel 66 in the direction of the arrow P4, press with a relatively high force against the lower area of the supplied banknote 38 and deform themselves thereafter in order to be pulled through between the front-side lower edge of the stack 36 and the hub of the lower vane wheel 66. The vanes 74 to 78 project from the hub of the vane wheel 66 such that, upon a rotation in the direction of the arrow P4, they have to be swiveled toward the hub only by a relatively small angle in order to rest against the circumferential surface of the hub at least in part.
(65) In
(66) In
(67) The note retracting shutter 68 has a number of openings through which the upper vane wheel 54, the inclined deflector 64 and the pull-off wheel 32 are passed and contact a banknote 38 dependent on the operating mode of the separating and stacking module 30. For the further pull-off wheels 32, the further upper vane wheels 54 and the further inclined deflectors 64 further openings are provided in the note retracting shutter 68 so that these, too, can contact the banknote 38 through the note retracting shutter 68 in the same manner as already described for the feeding and separating elements 32, 54, 64. In the open position of the note retracting shutter 68, a feeding and removal opening is provided at least over a width of the widest banknote 38 which can be supplied, which opening is characterized by the arrow P5. Via this feeding and removal opening, a banknote 38 to be supplied reaches the feeding area 46. In the same manner, a banknote 38 to be removed from the cassette 12a is transported through the feeding and removal opening to the drive wheels 44 and is transported with the aid of the drive wheels 44, which are then driven in the opposite direction of the arrow P1, further to the transport elements 16a.
(68) In
(69) With the aid of a displacement carriage 82 driven by an electric motor 80 the stack 36 is moved into a separating position towards the pull-off wheel 32 so that the front side of the stack 36 or, respectively, the banknote 38 forming the front side of the stack 36 is pressed against the circumferential surface of the pull-off wheel 32 as well as against the surface of the further pull-off wheels 32 arranged parallel to the pull-off wheel 32. By moving the stack 36 towards the pull-off wheel 32, the inclined deflector 64 is swiveled about the axis of rotation 63, as a result whereof the spring 65 generating the pressure force of the inclined deflector 64 is biased or is further biased. For the removal of the banknote 38 forming the front side of the stack 36 the pull-off wheel 32 is rotated with the aid of a drive unit in the direction of the arrow P7, which direction is opposite to the direction of rotation of the pull-off wheel 32 in
(70) For the removal or further transport of a banknote 38 moved downwards with the aid of the pull-off wheels 32, the drive wheels 44 are driven in the direction of the arrow P8. The lower vane wheel 66 is positioned in a basic separating position such that its vanes 74 to 78 do not project into the transport path for the removal and further transport of the banknote 38.
(71) The displacement carriage 82 has axles 84, 86 which each extend from the displacement carriage 82 up to the side walls of the cassette 12a laterally bounding the stack 36, guiding wheels 92, 93 which engage in guiding rails 88, 90 being provided at the end of the axles. The guiding rails 80, 90 are formed in or at the side walls.
(72) In
(73) A drive unit 96 displaces a sliding element 98 via gear stages 100, 102 in the direction of the arrow P10. The gear stages 100, 102 each time create a gear reduction. The driven gear wheel of the gear stage 102 engages with a gear rack 104 formed on the sliding element 98 for displacing the sliding element 98. The sliding element 98 further has oblong holes 106, 108 through which non-illustrated guiding bolts project, the displacement area of the sliding element 98 being restricted by these guiding bolts and the oblong holes 106, 108. The sliding element 98 further has an inclination 110. In
(74) In
(75) Moreover, in the arrangement shown in
(76) Further, a drive unit 128 as well as a gear stage 130 are shown for driving the drive shaft 42 on which the drive wheel 44 is arranged. In the present embodiment, the drive units 128, 96, 80 are formed as electric motors, preferably as stepper motors or as DC motors, wherein also a part of the drive units can be designed as stepper motors and another part as DC motors.
(77) In
(78) In
(79) Alternatively, the pivoting of the note retracting shutter 68 takes place upon movement of the cassette 12a in the direction of the arrow P12 automatically via the spring force of the spring 116 since also upon a movement of the cassette 12a in the direction of the arrow P12 the guiding roll 134 of the lever arm 120 is guided along the inclination 110 of the sliding element 98 so that the lever 114 is pivoted by the spring force of the spring 116 and the note retracting shutter 68 is closed. Further, the cassette 12a has several interconnected lamellae 138a to 138g for closing the front side 140 of the cassette 12a. The lamellae 138a to 138g are connected to the respective adjacent lamellae such or, respectively, are formed in the connecting area such that a relative pivoting of the lamellae 138a to 138g about the axes of rotation 142a to 142e is possible within a limited angular range so that the lamellae 138a to 138g which are guided laterally in guiding rails 144 are guided along a curved track defined by the guiding rails. The lamellae 138a to 138g are shifted into an area underneath the banknote receiving area of the cassette 12a when the inserted cassette 12a is in an operating position. In the operating position, the feeding and separating elements can contact a banknote 38 arranged at the front side of the stack 36 through the openings in the note retracting shutter 68. In the closed state, the lamellae 138a to 138g cover both the substantially vertical front side 140 of the cassette 12a as well as an area underneath the note retracting shutter starting out from the front side 140 so that the entire feeding and removal area is completely covered by the lamellae 138a to 138g when the cassette 12a is removed from the safe 10.
(80) The moving of the lamellae 138a to 138g into the closed position shown in
(81) By the at least one engagement element which projects into the engagement opening, the lamellae 138a to 138g are again moved into the closed position shown in
(82) In
(83) Only the shaft 71 and the elements 158, 160a, 160b, 72a to 72e arranged thereon form part of the cassette 12a. The other elements of the gear stages 148, 150, 152, 154 as well as the electric motor 146 are arranged separately from the cassette 12a. When the cassette 12a is in an operating or working position inserted in the safe 10, a gear wheel of the gear stage 154 engages with the gear wheel 158 arranged on the shaft 71 of the cassette 12a so that the shaft 71 is driven and rotated when the driven shaft of the motor 146 is rotated.
(84) In
(85) In
(86) A further gear wheel 186 is arranged on the end of the shaft 55 opposite to the gear wheel 172, which gear wheel 186 is connected to the shaft 55 via a freewheeling mechanism so that a rotary motion of the stripping rollers 52a, 52b is possible in the direction of the arrows P20, P22 when the shaft 55 is not driven via the gear wheel 186 in the direction of the arrows P20, P22. For preventing a double pull-off, i.e. for preventing the simultaneous removal of two banknotes from the container 12a, the stripping rollers 52a, 52b are likewise driven in the direction of rotation of the arrows P20, P22 via the shaft 55 and the gear wheel 186. In other embodiments, the gear wheel 186 can be connected to the shaft 55 in a rotationally fixed manner, as a result whereof the freewheeling mechanism can be dispensed with. Then, the stripping rollers 52a, 52b are to be driven by a drive unit via the gear wheel 186 and the shaft 55 in the direction of the arrows P20, P22 when a banknote 38 is fed into the feeding area 46.
(87) In
(88) The drive shaft 34 is driven via the magnetic coupling 188 and the gear wheel 189 arranged on one end of the shaft 34. The opposite end of the shaft 34 is pressed in the direction of the note stack 36 with the aid of a pressure device 195. The pressure device 195 further comprises a pressure sensor which detects at least a position of the end of the drive shaft 34 held in the pressure device 195. By the spring-mounting of the pull-off wheels 32a to 32c which are preferably arranged on a common sleeve 196, the sleeve 196 being spring-mounted on the drive shaft 34, the pull-off wheels 32a to 32c can be pressed against the front side of the stack 36 oriented in parallel and with a desired preset pressure force so that the banknotes 38 to be removed from the cassette 12a are not pulled off in an inclined manner. The pull-off wheels 32a to 32c are arranged on the sleeve 196 in a rotationally fixed manner, the sleeve 196 being connected to the drive shaft 134 in a rotationally fixed manner. By the spring-mounting of the sleeve 196 on the drive shaft 34, however, a common pivoting of the pull-off wheels 32a to 32c is possible so that these orient in parallel relative to the front side of the stack 36 when the pull-off wheels 32a to 32c are pressed against this front side and thus enable a parallel pull-off of the banknote 38 present at the front side of the stack 36.
(89) The drive shaft 42 is driven via the gear wheel 198 arranged at one end of the drive shaft 42 via drive elements of a central distribution module arranged in the safe 10, which module drives further transport elements 16a to 16d of the transport path 18. This gear wheel 198 is designed as a double gear wheel and drives the drive side of the magnetic coupling 188. As a result thereof, no separate drive for driving the drive wheels 44 and the pull-off wheels 32 in the separating and stacking module 30 is required.
(90) By the separating and stacking module 30 according to the first embodiment of the invention a module separation between the cassette 12a and the feeding and separating elements takes place. As a result thereof, a simply constructed, cost-efficient cassette 12a can be used, the feeding and separating elements being arranged in the safe 10 or, respectively, in the automated teller machine and remaining in the safe 10 or, respectively, the automated teller machine when the cassette 12a is removed. The cassette 12a can be used in a first automated teller machine for the deposit and withdrawal of banknotes (cash recycling), and in the case of a new configuration of the same automated teller machine or in the case of a use of this cassette 12a in another automated teller machine it can be used as a mere withdrawal cassette 12a. It is advantageous to arrange the cassette 12a such that the front side of a banknote stack 36 contained in the cassette 12a is arranged vertically, i.e. that the stacking direction or, respectively, the stacking depth runs horizontally. The separating and stacking module 30 and the cassette 12a can however also be arranged such that the stacking direction or, respectively, the stacking depth extends vertically, the front side of the stack 36 at which the banknotes can be pulled off from the stack 36 and further banknotes can be supplied to the stack 36, then being arranged horizontally at the upper side of the stack 36.
(91) The upper two-vaned vane wheels 54 with rigid vanes 58, 60 are formed and arranged such that the enveloping circle of the vanes 58, 60 ends at the top approximately with the highest allowable note height and, in the horizontal basic stacking position, also supports a stack 36 formed of the smallest allowable banknotes 38 or, respectively, pushes it further into the cassette 12a. During a feeding operation for feeding a banknote 38, one vane change-over each takes place, i.e. before feeding the banknote 38 the first vane 60 contacts the front side of the stack 36 and after feeding the banknote 38 the second vane 58 contacts the front side of the stack 36. In this process, a dynamic triggering of the vane change-over takes place dependent on the detection of the banknote front edge of the banknote 38 to be supplied by the light barrier arrangement 39, the vane change-over time being selected such that a just supplied banknote 38 is moved towards the stack 36 or, respectively, is hit and pushed by the outer curvature of the curved vane end towards the stack 36. The vane change-over time is preferably set dependent on the size of the supplied banknote 38, i.e. is varied size-dependent. The inclined deflectors 64 guide a supplied banknote 38 away from the center of the vane 60, or respectively, 58 of the vane wheel 54 and towards the front side of the stack 36. The vanes 74, 76, 78 of the lower vane wheel are tangentially connected to a hub of the vane wheel 66, the front area of the vanes 74, 76, 78 each having a curvature. The curvature is formed such that in the direction of rotation of the vane wheel 54 the vane tips are ahead of the remaining part of the vanes 58, 60 when a banknote 38 is supplied.
(92) The main drive shaft 42 with the drive wheels 44 is continuously driven via an electric motor for driving the transport elements of the transport path 18, wherein the drive shaft 34 with the pull-off wheels 32 arranged thereon can be selectively coupled or decoupled with the drive of the drive wheels 44 via the magnetic coupling 188. The continuous drive of the drive wheels 44 as well as the selective drive of the pull-off wheels 32 takes place via a central drive for the transport elements 16a to 16d arranged in the safe 10, which central drive has a high torque reserve so that banknotes which are difficult to separate, e.g. adhering banknotes which are hot of the press or notes with polymer foil, can likewise be separated with the aid of the pull-off wheels 32 and can be transported with the aid of the drive wheels 44. In this process, the pull-off wheels 32 are driven via the activated magnetic coupling 188 until the banknote has reached the detection area of the light barrier arrangement 75 arranged in the area of the drive wheels 44. This has the advantage that the entire operation for the pull-off and the further transport of the banknote 38 does not fall out of step in the case of delays in the pull-off or the further transport, for example as a consequence of adhering banknotes, as this might occur in the case of rigidly mechanically coupled separating drives. Rather, upon arrival of a sheet edge of the banknote 38 to be removed, the transport is simply continued so that the control for the transport of the banknote 38 takes place in an event-driven manner dependent on the event arrival of the sheet edge of the pulled-off banknote 38 in the detection area of the light barrier arrangement.
(93) For a trouble-free feeding of a banknote into the cassette 12a, at least in the first embodiment of the invention the following conditions are preferably met: 1. In front of the front side of the banknote stack 36 a free feeding area (free space) 46 for the banknote 38 to be supplied has to be created against the stack pressure of the stack 36 and should be kept free from the stack pressure of the stack 36. 2. The rear edge of a supplied banknote 38 should be supplied to the stack 36 as soon as it has left the contact area between drive wheel 44 and pressure roller 50 or, respectively, between drive wheel 44 and stripping roller 52.
(94) The stack pressure already mentioned is determined in particular by the stack thickness, the condition and the properties of the banknotes arranged in the stack 36, and the position of the displacement carriage 82. Almost over the entire time period during which the banknote 38 to be supplied is transported into the feeding area 46, the stack 36 is pushed out of the feeding area 46 with the aid of the upper vane wheels 54. For this, several vane wheels 54 are arranged on the drive shaft 62 so as to be distributed over the maximum allowable note width, which drive shaft is arranged horizontally in the first embodiment of the invention. The drive shaft 62 with the vane wheels 54 is preferably driven with the aid of a stepper motor, the drive shaft 62 being rotated by 180 every time a banknote 38 is supplied. As already mentioned, the vane wheels 54 are driven such that the front edge of a supplied banknote 38 does not contact the vane 58, 60 projecting into the feeding area 46 but that there is rather a minimum distance between the front edge of the supplied banknote 38 and the vane 58, 60 by means of a suitable control of the stepper motor for driving the drive shaft 62. The vanes 58, 60 have a relatively small width. In the present embodiment they have a width of 6 mm. In the breaks between the feeding of two banknotes, the vane wheels 54 are in the basic stacking position in which the vane 60 projecting into the feeding area 46 contacts the note stack 36 below the lowest allowable note height. Preferably, in the present embodiment the lowest allowable note height is 58 mm.
(95) Further, the pressure element 45 already described in connection with
(96) The circulation time of the upper vane wheel 54 given a rotation by 180 is preferably preset such that the supplied banknote 38 is pushed by the second vane 58 to the front side of the stack 36 and is pressed against this stack as soon as the supplied banknote 38 has left the contact area between the drive wheel 44 and the pressure roller 50. The inclined deflectors 64 in particular cause that relatively large banknotes which are arranged as a stack 36 in the cassette 12a do not bend above the vane 60 pressing against the front side of the stack 36 in the basic stacking position and project into the area above the vane 60 which is in the basic stacking position. Without these inclined deflectors 64 the banknote arranged at the front side or several banknotes of the stack 36 could be pulled upwards by the vane 60 when the vane wheel 54 rotates. When a banknote 38 is supplied, the lower vane wheel 66 is preferably rotated together with the drive wheels 44, wherein the lower vane wheels 66, as already described, can be driven or rotated independent of the counter-rotation shaft 55. When the banknote 38 is transported into the feeding area 46, the flexible vanes 74 to 78 of the lower vane wheels 66 are elastically deformed and wound around the hub of the respective vane wheel 66 so that the wound vanes 74 to 78 are arranged in a spiral-shaped manner. As soon as the rear edge of the banknote 38 leaves the contact area between the drive wheel 44 and the pressure roller 50 or, respectively, between the drive wheel 44 and the stripping rollers 52a, 52b, subsequently the first vane 74 to 78 engaging under the banknote rear edge hits against the lower area of the banknote 38 and presses this lower area upwards and against the stack 36.
(97) The lower vane wheels 66 are likewise driven by a separate stepper motor which, via a freewheeling mechanism, drives the shaft 55 with the stripping rollers 52a, 52b arranged thereon so that the stripping rollers 52a, 52b are likewise driven in feeding direction of the banknote 38 when a banknote 38 is supplied, and thus at least do not impede the feeding of the banknote 38. As already mentioned, the lower vane wheels 66 each have three vanes 74 to 78, the base points of which are not uniformly distributed about the circumference and in the present embodiment leave a gap of 180. For separating, i.e. removing, a banknote 38 from the cassette 12a, the lower vane wheel 66 is then oriented such that no vane 74 to 78 projects into the transport path for the transport of the pulled-off banknote 38. These positions of the vanes 74 to 78 of the lower vane wheel 66 are illustrated in
(98) The vanes 74 to 78 are, as explained, not arranged centrally on the hub of the lower vane wheel 66 but project tangentially in a lateral direction. As a result thereof, the vanes 74 to 78 can perform the described elastic deformation while the material is only subject to relatively low stress. In particular, the base zone of each of the vanes 74 to 78 connected to the hub of the vane wheel 66 is not angled as much as in the case of a central connection of the vanes 74 to 78 to the hub when the vanes 74 to 78 are placed against the hub upon rotation of the vane wheel 66.
(99) In its inactive position illustrated in
(100) With the aid of the drive of the note retracting shutter 68 already described in connection with
(101) In the following the procedure for feeding a banknote is to be briefly summarized once again. After insertion of the cassette 12a and after opening of the note retracting shutter 68, the displacement carriage 82 is displaced in the direction of the separating and stacking module 30 synchronously to the bottom belt 70. As a result thereof, the displacement carriage 82 presses the banknotes contained in the note receiving area of the cassette 12a in the form of a stack 36 against the pull-off wheels 32. The pull-off wheel shaft 34 is, as already explained, spring-mounted on one side, wherein with the aid of a sensor arrangement the deflection of the non-driven shaft end of the drive shaft 34 is detected analogously and/or digitally. With the aid of the detected deflection, a pressure optimization during separation i.e. during pull-off of the banknotes, can be performed.
(102) After the displacement carriage 82 has pressed the banknote stack 36 contained in the cassette 12a with a preset maximum pressure against the pull-off wheels 32, the direction of motion of the displacement carriage 82 is reversed and a preset retraction distance is covered. Owing to different note qualities, in particular in the case of the note stack 36 having relatively many banknotes the required stacking space varies so that given a constant retraction distance of the displacement carriage 82 a varying pressing force is exerted from the notes onto the feeding and separating elements of the separating and stacking module 30. In a first step, the displacement carriage 82 is moved away by a first distance from the separating and stacking module 30. Subsequently, an indirect stack pressure detection is performed, wherein the upper vane wheel 54 is to be rotated from the basic separating position into the basic stacking position. Parallel to this rotary motion of the upper vane wheel 54, the displacement carriage 82 is moved further away from the separating and stacking module 30, wherein at the same time the bottom belts 70 are driven such that they transport the banknotes standing on the belts 70 away from the separating and stacking module 30. This is continued until the vanes 58, 60 of the upper vane wheel 54 have reached the basic stacking position or, respectively, until the sensor arrangement 126 no longer detects a banknote in the detection area.
(103) During the described positioning operation of the displacement carriage 82, the upper vane wheel 54 is driven with the aid of the stepper motor at a reduced stepper motor current and a frequency which is reduced compared to the normal drive frequency. The allowable note pressure can thus be determined by the torque of the stepper motor. Indeed, stepper motors are basically unsuitable for torque regulations since a stepper motor skips steps when a threshold torque is exceeded, the torque becoming zero when steps are skipped. The torque is only build up again after four further steps. In order to prevent a backward movement, a freewheeling mechanism is arranged on the drive shaft 62. During the setting operation, a pulsating control signal for controlling the stepper motor is used which, with every pulse, rises up to the value valid for the chosen low frequency. This is repeated until the basic feeding position or, respectively, basic stacking position of the vane wheel 54 is reached, in which the non-curved area of the vanes 58, 60 is oriented substantially horizontally.
(104) Alternatively, a DC collector motor or a brushless DC motor can be used instead of the stepper motor. Owing to feasible torque regulations, such motors are better suitable for setting the stack pressure and thus are better suitable for positioning the displacement carriage 82. However, then a position detection and regulation for detecting the angular position of the drive shaft 62 or, respectively, of the upper vane wheel 54 are required. Such a position regulation is relatively complex.
(105) After setting the stack pressure of the note stack 36 at the vanes 58, 60 of the upper vane wheel 54, a positioning control is performed in the lower area of the banknotes arranged as a stack 36. For this, a sensor arrangement 126 designed as a transverse light barrier is provided which is arranged at the boundary of the maximum required feeding area 46 in the so-called stack base zone and thus monitors the area in front of the front side of the stack 36. In the case of continuously rotating lower vane wheels 66, the bottom belts 70 and the vane wheels 72 arranged in the cassette 12a are likewise driven for the transport of the note stack 36 from the feeding area 46 into the note receiving area of the cassette 12a until the light barrier arrangement 126 no longer detects a banknote in its detection area. The feeding of banknotes 38 then takes place with continuously rotating drive wheels 44 and continuously rotating lower vane wheels 66. The pull-off wheels 32 are also at least temporarily rotated via the magnetic coupling 188, in particular in order to prevent that the front edge of the supplied banknote 38 gets stuck on the circumferential surface of the pull-off wheels 32.
(106) During each transaction, up to 200 banknotes 38 can be supplied to the cassette 12a. Per supplied banknote 38, the displacement carriage 82 is moved synchronously with the bottom belts 70 by a preset retraction distance away from the separating and stacking module 30, i.e. moved backwards in the cassette 12a. If this preset retraction distance is insufficient, a banknote 38, after having been supplied, will remain at least in part in the detection area of the monitoring light barrier arrangement 126 and will be detected by it since this banknote 38 could not be pressed sufficiently far into the banknote receiving area. The preset retraction distance is in particular not sufficient when used banknotes 38 have a resulting greater note thickness in the stack due to their deformation. The preset retraction distance of the displacement carriage 82 is thus not sufficient in order to provide sufficient stacking space for the supplied banknotes. If the light barrier arrangement 126 detects a banknote in the detection area, the displacement carriage 82 is moved away from the separating and stacking module 30 by an additional retraction distance.
(107) Further, an intermediate compression is provided since in the case of a too long retraction movement of the displacement carriage 82 that has been preset or in the case of uneven banknotes a relatively poor filling level would be reached in the cassette 12a. For this, prior to a further transaction, an intermediate compression operation is provided when more than 150 banknotes, at maximum 200 banknotes, have been supplied. The operation corresponds to the already described operation for setting the stack pressure after feeding the cassette 12a or, respectively, prior to positioning the upper vane wheel 54 in the basic stacking position. By means of this intermediate compression, the air gaps created during the retraction of the displacement carriage 82 by a preset generous increment are at least partially removed from the stack 36 in that the entire stack 36 is compressed.
(108) After a separation in which the non-curved areas of the vanes 58, 60 of the upper vane wheel 54 are oriented substantially vertically, the vane wheel 54 is again rotated into a basic stacking position in which the non-curved areas of the vanes 58, 60 of the upper vane wheel 54 are oriented substantially horizontally. In this basic stacking position, all banknotes of the stack 36 are arranged in the cassette 12a so that the cassette 12a can be removed from the safe 10 as soon as the note retracting shutter 68 has been pivoted inward. As already mentioned, the note retracting shutter 68 is pivoted into the inactive position with the aid of the drive for the note retracting shutter 68 illustrated in
(109) In
(110) The endless transport belts 202 to 206 are guided over upper deflection rollers 212 to 216 which have lateral guides of the type of a belt pulley for the lateral guidance of the endless transport belts 202 to 206. The deflection rollers 212 to 216 are connected to a drive shaft 218 in a rotationally fixed manner, which shaft can be driven via an electric motor 220. The shaft 218 is driven via a belt drive 222. Further, for each transport belt 202 to 206 one lower deflection roller 224 to 228 each is provided, which are arranged on a drive shaft 230 for driving the pull-off wheels 208, 210 such that they rotate freely and are kept in their axial position on the drive shaft 230 via suitable axial stop elements. The endless transport belts 202 to 206 as well as the transport flaps 202a to 206a have a perforation with several holes equally spaced to one another along the circumference of the endless transport belt 202 to 206. The upper deflection rollers 212 to 216 have projecting sprockets which are complementary to the perforation of the transport belts 202 to 206, which sprockets engage with the perforation so that both a further lateral guidance as well as a slip-free drive of the transport belts 202 to 206 is provided.
(111) The transport belts 202 to 206 are driven in the direction of the arrow P50. With the aid of engagement elements which are each preferably designed as a one-vaned vane wheel 232 to 240, a gap can be created or increased between the circulating transport belt 202 to 206 and the downwardly open transport flaps 202a to 206a so that the transport belts 202 to 206 assume a basic feeding position.
(112) In the same manner as described in the first embodiment of the invention, the feeding of a banknote 38 takes place via the drive wheels 44. By opening the transport flaps 202a to 206a with the aid of the vanes 232 to 240, a feeding area between the circulating transport belt 202 to 206 and the banknote stack 36 resting against the outside of the transport flaps 202a to 206a is created. A banknote 38 to be supplied is transported into this feeding area. As a result thereof, an area of this banknote 38 each is inserted into the transport flaps 202a to 206a or, respectively, guided between the transport flaps 202a to 206a and the transport belts 202 to 206. After areas of the supplied banknote 38 are positioned in the transport flaps 202a to 206a, the transport belts 202 to 206 are driven in the direction of the arrow P50 substantially at the same circulation speed as the speed at which the supplied banknote 38 has been conveyed into the transport flaps 202a to 206a with the aid of the drive wheels 44. Further, non-illustrated stripping elements are provided which prevent the banknote which is arranged with areas thereof in the transport flaps 202a to 206a from a further circulation with the transport belts 202 to 206, and as a result thereof, pulls the banknote out of the transport flaps 202a to 206a when the transport belts 202 to 206 are driven further. These stripping elements are arranged such that the banknote 38 pulled out of the transport flaps 202a to 206a is positioned opposite to the front side of the stack 36 already contained in the cassette 12a. Further, pressure elements 242 to 248 are provided which, via a pull magnet, come out of the areas between the transport belts 202 to 206 and which, in this process, press the banknote 38 positioned opposite to the front side of the stack 36 already contained in the cassette 12a against the front side of the stack 36 so that the supplied banknote 38 forms the new front side of the stack 36.
(113) The lower area of a supplied banknote 38 is additionally pressed against the banknote stack 36 by the vane wheels 232 to 240. Further, in

(121) The transport belts 202 to 206 with the transport flaps 202a to 206a are also referred to as scaled belts since the transport flaps 202a to 206a rest like scales on the respective transport belt 202 to 206. Preferably, both the endless transport belts 202 to 206 as well as the transport flaps 202a to 206a are made of a polyester foil having a uniform thickness in the range between 0.1 to 0.75 mm, preferably in the range between 0.2 to 0.35 mm. A thickness of 0.25 mm has proven to be advantageous. The separating and stacking module 200 according to the second embodiment of the invention is also particularly suitable for a vertical cassette arrangement, i.e. an arrangement of the cassette in such a way that the front side of the stack 36 is arranged in a horizontal plane preferably at the top of the stack.
(122) A particular advantage of the separating and stacking module 200, 252 with the transport belts 202 to 206 is that a banknote 38 to be supplied is protected in the transport flaps 202a to 206a when it is transported in front of the front side of the stack 36. The banknote 38 is covered in the front note section by the relatively wide transport flaps 202a to 206a and has no direct contact with the front side of the stack 36 in the area of the transport flaps 202a to 206a. As a result thereof, the supplied banknote 38 cannot get caught in projecting areas of used banknotes. Compared to other embodiments, also lower demands on the stiffness of the banknotes to be supplied with respect to a bending are made. By means of the transport belts 202 to 206 a flat and low-mass design of the feeding elements is possible. Further, by means of the transport belt 202 deflected over two deflection rollers with the transport flaps 202a to 206a a linear guidance of the banknote is achieved. The endless transport belt 202 with the at least one transport flap 202a, preferably with two transport flaps each, can be made of two punched foils which are welded to one another at at least two connecting points, preferably by one welded joint each, to form the endless transport belt 202 with the transport flap 202a. As a welding process, in particular an ultrasonic welding process is suitable.

(125) In addition to the separating and stacking wheels 272 to 276 two additional stacking wheels 292, 294 are provided which have no pull-off elements and thus have no separating function. The separating and stacking wheels 272 to 276 each have two pull-off elements 272a, 272b, 274a, 274b, 276a, 276b which can be moved out of the circumferential surface of the separating and stacking wheels 272 to 276. The outer surfaces of these pull-off elements 272a to 276b are each profiled with transverse grooves and have a relatively high coefficient of friction so that banknotes can be moved or, respectively, pulled-off with the aid of the pull-off elements 272a to 276b already with a relatively small pressing force. For example, at least the surface of the pull-off elements 272a to 276b is made of a rubber material.
(126) Further, the stacking and separating wheel shaft 270 has control levers 296, 298 whose end remote from the stacking and separating wheel shaft 270 serves to control the movement of the retaining or, respectively, pressure elements 190. Further, via the control levers 296, 298 clamping elements arranged in the stacking and separating wheels 272 to 276 can be controlled via a cam disk arranged on the already mentioned parallel shaft and/or via cam disks arranged in the stacking and separating wheels. The belt drives 280 to 290 for driving the cam disks, of which the belt pulleys 280 to 284 arranged on the stacking and separating wheel shaft 270 and the toothed belts 286 to 290 are illustrated in

After the front edge of the banknote 38 has reached the front side of the chamber 272c or immediately thereafter, the clamping of the banknote 38 in the chamber 272c takes place in a manner controlled via the cam disk and controlled via the lever 320a. In this process, the lever 320a is pressed against the spring force of a spring 322a against the outer side of the chamber 272c.
