This section provides background information related to the present disclosure which is not necessarily prior art.
1. Technical Field
The invention relates to a device for handling notes of value which has a first, a second and a third transport path, wherein the notes of value can be transported along each transport path. Further, the device has a switch via which the three transport paths can be connected to each other and with the aid of which the notes of value can be rerouted from one of the transport paths to another of the transport paths according to the switch position. Further, the device comprises a first transport element with the aid of which the notes of value can be supplied from the switch to the first transport path and/or from the first transport path to the switch, a second transport element with the aid of which the notes of value can be supplied from the switch to the second transport path and/or from the second transport path to the switch and a third transport element with the aid of which the notes of value can be supplied from the switch to the third transport path and/or from the third transport path to the switch.
2. Discussion
The device is in particular an automated teller machine, an automatic cash register system and/or an automatic cash safe. When depositing and/or withdrawing notes of value they are transported along transport paths, wherein the notes of value can be rerouted with the aid of the switch between three transport paths. The switch is therefore also referred to as three-way-switch. In order to realize all possible transport directions between the three transport paths, i.e. in order to reroute the notes of value from each of the three transport paths in any other of the three transport paths with the aid of the switch, it is necessary that the direction of rotation of at least one of the transport elements can be reversed relative to the direction of rotation of the other transport elements.
In known three-way-switches this is realized by driving two of the transport elements via a central drive unit of the device, while the third transport element is driven via a separate drive unit such that the direction of rotation of the third transport element can be adjusted independently from the direction of rotation of the central drive unit and thus the direction of rotation of the first two transport elements. What is disadvantageous here is that by providing a separate drive unit for the third transport element installation space is required and costs incur.
From Document WO 2009/018879 A1 a three-way-switch, for redirecting sheet-shaped media is known
It is an object of the invention to specify a device for handling notes of value with the aid of which notes of value can be transported easily between various transport paths and which has a simple and compact design.
In the device according to the invention, the three transport elements are driven with the aid of the same drive unit, wherein the direction of rotation of at least one of the transport elements can be reversed relative to the direction of rotation of the other transport elements. In this way, it is achieved that now only one drive unit is required and still all transport directions between the three transport paths can be realized. Thus, the notes of value can be transported from each transport path in any other transport path without an additional separate drive unit being required. In this way, installation space is saved such that the device is constructed compact and cost-efficient. The drive unit is in particular a central drive unit of the device, in particular a central drive unit of an automated teller machine, an automatic cash register system and/or an automatic cash safe. By reversing the direction of rotation of one of the transport elements relative to the direction of rotation of the other transport elements is understood that the direction of rotation of said one transport element is reversed, while the direction of rotation of said other two transport elements is maintained or that the direction of rotation of said other two transport elements is reversed when the transport direction of said one transport element is maintained.
It is advantageous when in a first operating state, the first transport element has a first direction of rotation, the second transport element has a second direction of rotation and the third transport element has a third direction of rotation, and when in a second operating state, the first transport element has the first direction of rotation, the second transport element has the second direction of rotation and the third transport element has a fourth direction of rotation opposite to the third direction of rotation. Thus, in the second operating state relative to the first operating state, the directions of rotation of the first two transport elements are maintained, whereas the direction of rotation of the third transport element is reversed such that the direction of rotation of the third transport element is reversed relative to the direction of rotation of the first two transport elements. Thus, it is achieved that all possible transport directions can be realized, i.e. that the notes of value can be transported both from the first to the second, from the second to the first, from the second to the third, from the third to the second, from the first to the third and from the third to the first transport path.
Further, it is advantageous when in a third operating state, the first transport element is driven with a fifth direction of rotation opposite to the first direction of rotation, the second transport element is driven with a sixth direction of rotation opposite to the second direction of rotation and the third transport element is driven with the third direction of rotation. In this way, it is in turn achieved that by switching between the first and the third operating state all possible transport directions can be realized.
In a preferred embodiment of the invention, the first, the second and the third direction of rotation are identical such that in the first operating state, all transport elements are driven with the same direction of rotation. In this case, in the second operating state, the direction of rotation of the third transport element is reversed, while the direction of rotation of the first two transport elements is maintained. In contrast, when switching from the first in the third operating state the direction of rotation of the third transport element is maintained, while the direction of rotation of the first two transport elements is reversed.
In a preferred embodiment of the invention, notes of value can be transported from the first transport path to the second transport path and/or from the second transport path to the first transport path in a first switch position, notes of value can be transported from the first transport path to the third transport path and/or from the third transport path to the first transport path in a second switch position and notes of value can be transported from the second transport path to the third transport path and/or from the third transport path to the second transport path in a third switch position. In this way, it is achieved that according to the switch position all possible transport directions of the notes of value can be realized.
The switch comprises in particular a switch shaft on which at least one guiding finger, preferably a plurality of guiding fingers, for guiding the notes of value is arranged in a rotationally fixed manner. The switch shaft is engaged, in particular via a gear wheel assembly, with a cam disk, wherein the cam disk can be rotated with the aid of an adjustment unit in at least a first, a second and a third preset position, wherein the switch shaft is rotatable in one of the three switch positions according to the position of the cam disk. In this way, it is achieved that the three switch positions can be reliably adjusted via the cam disk in an easy manner. The switch shaft is connected to the cam disk in particular via a gear segment which is guided within a link of the cam disk via a pin. The link of the cam disk respectively includes a portion with a constant radius on the three preset positions such that the pin is also in case of low tolerances of the rotation of the cam disk arranged within this region with the same radius such that the switch shaft has the correct position.
In the first switch position and in the second switch position, the transport elements are preferably in the first operating state and in the third switch position, in the second operating state or in the third operating state. In order to realize all transport directions of the notes of value, the direction of rotation of the third transport element has to be changed relative to the direction of rotation of the other two transport elements only in case of one of the switch positions, whereas in case of the other two switch positions the direction of rotation of the transport elements can be maintained. It is advantageous when the direction of rotation is also only changed if necessary and unnecessary switching of the direction of rotation is prevented. In this way, wear of the respective component parts is reduced.
In an advantageous embodiment of the invention, the device comprises a reverse gear, which, in a first position of the third transport element, drives with the same direction of rotation with which the first transport element rotates and in a second position of the third transport element, drives with the direction of rotation opposite to the direction of rotation of the first transport element. In this way, it is easily achieved that all three transport elements can be driven via the drive unit and the direction of rotation of the third transport element can be reversed relative to the direction of rotation of the first and the second transport element independently from the direction of rotation of the first two transport elements. The reverse gear is in particular a tumbler gear.
The reverse gear comprises in particular a first gear wheel which in a first position meshes with a gear wheel connected to the third transport element in a rotationally fixed manner, which in a second position meshes with the gear wheel connected to the transport element in a rotationally fixed manner, wherein in the first position the second gear wheel does not contact the gear wheel connected to the third transport element in a rotationally fixed manner and in the second position the first gear wheel does not contact the gear wheel connected to the third transport element in a rotationally fixed manner and the first gear wheel and the second gear wheel are engaged with each other. In this way, it is achieved that by pivoting the reverse gear the gear wheel connected to the third transport element can be selectively engaged with the first and the second gear wheel. As the first and the second gear wheel mesh with each other, they have different directions of rotation. Depending on with which gear wheel the gear wheel firmly connected to the transport element meshes, thus also the direction of rotation of the third transport element is reversed. Here, the first gear wheel and the second gear wheel and thus in turn also the third transport element are driven via the drive unit. Here, the reverse gear is mainly driven via a central drive unit of the device.
It is advantageous when the reverse gear is connected to the switch such that in case of an adjustment of the switch positions the reverse gear is also pivoted from the first in the second position, when this is necessary for the desired transport direction. It is particularly advantageous when this pivoting of the gear takes place automatically according to the switch position. In this way, it is achieved that no improper adjustments of the reverse gear relative to the switch occur and thus notes of value jams are prevented.
It is in particular advantageous when the reverse gear is connected to the switch via a coupling element and when an adjustment unit is provided which adjusts the switch position of the switch. In the first switch position the reverse gear is arranged in the first position, in the second switch position the reverse gear is also arranged in the first position and only in the third switch position the reverse gear is arranged in the second position. In this way, it is achieved that the reverse gear is only adjusted during the adjustment from the first in the third or from the second in the third switch position or vice versa from the third in the first or from the third in the second switch position such that an unnecessary adjustment of the reverse gear and thus unnecessary wear is prevented. The adjustment unit pivots via the connection via the coupling element the reverse gear from the first position in the second position when the locking unit adjusts the switch from the first switch position in the third switch position or from the second switch position in the third switch position. Likewise, the adjustment unit pivots via the connection via the coupling element the reverse gear from the second position in the first position when the locking unit adjusts the switch from the third switch position in the first switch position or from the third switch position in the second switch position. By this purely mechanical coupling between the adjustment unit and the reverse gear it is achieved that no electronics is required for the control of the reverse gear and thus the complexity and the fault liability are reduced.
A pin stationarily connected to the coupling element can be guided within an oblong hole of a first guiding element connected to the reverse gear, wherein the pin is additionally guided within a groove of a stationary second guiding element. The second guiding element is in particular stationarily connected to a housing or a rack. The groove of the second guiding element comprises a first and a second leg, wherein the first leg and the second leg span an angle between 100° and 170°, in particular between 120° and 150°. By the double guidance of the pin within the oblong hole connected to the reverse gear and the stationarily arranged groove it is achieved that the reverse gear is only pivoted from the first position in the second position when the adjustment unit adjusts the switch from the first switch position in the third switch position or from the second switch position in the third switch position, and is only pivoted from the second position in the first position when the adjustment unit adjusts the switch from the third switch position in the first switch position or from the third switch position in the second switch position. In this way, in particular a simple mechanical arrangement is made possible by means of which the reverse gear is only pivoted automatically along during the adjustment of the switch, when this is necessary for the intended transport direction.
The transport elements can respectively comprise at least one roll, at least one belt and/or at least one roller. The transport elements comprise in particular respectively one pair of rolls which comprises preferably a drive roll driven by the drive unit and a non-driven pressure roll. The notes of value are transported through these rolls. In this way, a secure guidance of the notes of value is achieved and notes of value jams and damage of the notes of value are prevented.
The drive unit comprises in particular an electric motor, preferably a DC motor or a stepper motor.
The first transport element is in particular arranged on a first shaft in a rotationally fixed manner, the second transport element is arranged on a second shaft in a rotationally fixed manner and the third transport element is arranged on a third shaft in a rotationally fixed manner. The reversal of the direction of rotation of the individual transport elements relative to the direction of rotation of the other two transport elements is achieved by reversing the shaft on which said one transport element is arranged relative to the direction of rotation of the other two shafts.

The device 10 comprises three pairs of rolls 24a to 24c, which respectively comprise at least one driven drive roll 26 to 30. The drive rolls 26 to 30 can be driven via a central drive unit of the device 10. The first pair of rolls 24a in addition to the driven drive roll 26 has a further driven roll 32. Whereas the other two pairs of rolls 24b, 24c in addition to the drive rolls 28, 30 respectively have one pressure roll 34, 36 which is not driven itself. In an alternative embodiment of the invention, the roll 32 of the first pair of rolls 24a can also be a non-driven pressure roll. During the transport along the transport paths 12 to 16 the notes of value are transported through the rolls 26 to 36 of the respective transport paths 12 to 16. As indicated by the double arrow P1, the notes of value can be supplied from the first transport path 12 to the switch 18 and from the switch 18 to the first transport path 12 with the aid of the first pair of rolls 24a. As indicated by the double arrow P2, the notes of value can likewise be supplied from the second transport path 14 to the switch 18 and from the switch 18 to the second transport path 14 with the aid of the second pair of rolls 24b. Corresponding to the double arrow P3 the notes of value can be supplied from the third transport path 16 to the switch 18 and vice versa from the switch 18 to the third transport path 16 with the aid of the third pair of rolls 24c. The direction of rotation of the central drive unit can be reversed such that the directions of rotation of the drive rolls 26 to 30 can also be reversed. In this way, depending on the rotation, the notes of value can be supplied from the respective transport path 12 to 16 to the switch 18 and from the switch 18 to the respective transport path 12 to 16.
As already mentioned, the drive rolls 26 to 30 are driven by a central drive unit of the device 10, in particular an electric motor. For this, the drive rolls 26 to 30 are in particular connected via a shaft, a belt, a chain and/or a gear wheel arrangement to the drive unit and/or to each other. In a first operating state, the drive rolls 26 to 30 are all driven with the same first direction of rotation which is indicated by the arrows P4 to P6. When the direction of rotation of the central drive unit is reversed, the directions of rotation of the drive rolls 26 to 30 are reversed as well such that said drive rolls 26 to 30 are driven opposite to the arrows P4 to P6 but still all have the same direction of rotation. In this operating state, in which the three drive rolls 26 to 30 have the same direction of rotation, the notes of value can be supplied from the first transport path 12 to the second transport path 14, from the first transport path 12 to the third transport path 16, from the second transport path 14 to the first transport path 12 and from the third transport path 16 to the first transport path 12.
However, in order to supply the notes of value from the second transport path 14 to the third transport path 16 or from the third transport path 16 to the second transport path 14, the direction of rotation of the second drive roll 28 or the third drive roll 30 has to be reversed relative to the direction of rotation of the other two drive rolls 26 to 30. Therefore, in the present embodiment, the direction of rotation of the drive roll 30 is reversed relative to the direction of rotation of the other two drive rolls 26, 28 in order to transport the notes of value between the second transport path 14 and the third transport path 16. In this second operating state, the first and the second drive roll 26, 28 rotate in the direction of the arrows P5 and P6, whereas the third drive roll 30 is rotated opposite to the direction of rotation of the first and the second drive roll 26, 28 and thus opposite to the direction of the arrow P6. Vice versa, the first and the second drive roll 26, 28 can likewise rotate opposite to the arrows P4 and P5 and the third drive roll 30 can rotate in the direction of the arrow P6.
Alternatively, it is also possible that in a third operating state, the direction of rotation of the first drive roll 26, 28 is reversed relative to the direction of rotation of the third drive roll 30 to realize thus also all possible transport directions of the notes of value between the transport paths 12 and 16. Likewise it is possible that not the direction of rotation of the third drive roll 30 is reversed relative to the direction of rotation of the first and second drive roll 26, 28, but that the direction of rotation of the first drive roll 26 is reversed relative to the direction of rotation of the second and the third drive roll 28, 30 or that the direction of rotation of the second drive roll 28 is reversed relative to the direction of rotation of the first and third drive roll 26, 30. Crucial is only that the direction of rotation of one of the drive rolls 26 to 30 can be reversed relative to the direction of rotation of the other two drive rolls 26 to 30 regardless in which direction of rotation the other two drive rolls rotate. Only in this way it is possible that the notes of value can be transported in any direction between the transport paths 12 to 16 according to the switch position.
The precise mechanical arrangement which is used for reversing the direction of rotation of the third drive roll 30 relative to the direction of rotation of the first and the second drive roll 26, 28 will be described below in more detail in connection with

As can be seen very well in
In an alternative embodiment of the invention, also more than two pairs of rolls can be arranged on the respective shafts 38a to 38f. The more pairs of rolls 24a to 24c are arranged on the respective shafts 28a to 28f, the more securely the notes of value are guided during the transport along the transport paths 12 to 16 and the more securely banknote jams are prevented.
The shafts 38a to 38d are connected via a gear wheel arrangement to the central drive unit with the aid of which the shafts 28a to 28d and thus the pairs of rolls 24a to 24c can be driven. The central drive unit as well as the gear wheel arrangement, belt arrangement and/or shaft arrangement with the aid of which the individual shafts 38a to 38d are connected to each other, are not illustrated completely in

The reverse gear 48 comprises a base plate 50 and five gear wheels 52 to 60. The first gear wheel 52 is, like the base plate 50, rotatably mounted about an axis 62. The first gear wheel 52 engages a gear wheel 64 which is connected to the central drive unit of the device 10 via a shaft 66.
The gear wheels 54 to 60 of the reverse gear 48 are rotatably connected to the base plate 50, wherein the first gear wheel 52 meshes with the second gear wheel 54, the second gear wheel 54 meshes with the third gear wheel 56, the third gear wheel 56 meshes with the fourth gear wheel 58 and the fourth gear wheel 58 meshes with the fifth gear wheel 60. Thus, all gear wheels 52 to 60 are driven by the central drive unit via the gear wheel 64. As the fourth gear wheel 58 directly meshes with the fifth gear wheel 60, the two gear wheels 50, 60 have a different direction of rotation.
In the first position of the reverse gear 40, illustrated in
In the position illustrated in
In
For changing from the first position into the second position the reverse gear 48 is pivoted about the axis 62 in the direction of the arrow P7 until the gear wheel 68 is no longer engaged with the fifth gear wheel 60 and meshes with the fourth gear wheel 58. Vice versa, the reverse gear 48 is brought from the second position in the first position by pivoting it opposite to the direction of the arrow P7. Changing between the positions of the reverse gear 48 takes preferably place during the standstill of the drive unit and thus the gear wheels 52 to 60, 64, 68 or in case of low speed of the gear wheels 52 to 60, 64, 68. Alternatively, the adjustment of the reverse gear 48 can also take place while the gear wheels 52 to 60, 64, 68 rotate with the normal operating speed.

In the third switch position shown in
Further, the gear segment 81 is connected via a pin 88 to a coupling element 90, wherein the coupling element 90 is rotatably connected to the gear segment 81 by the pin 88. On the end of the coupling element 90 opposite to the end connected to the pin 88 with the gear segment 88 the coupling element 90 includes a hole in which a further pin 92 is arranged. A first end of the pin 92 is guided within an oblong hole 94 of a first guiding element 96. The first guiding element 96 is firmly connected to the base plate 50 of the reverse gear 48 and thus firmly connected to the reverse gear 48. The broad end of the pin 92 is guided within a groove 98 of a second guiding element 100. The second guiding element 100 is firmly connected to a stationary rack 102 (see
In the operating state shown in
In
By moving the gear segment 81 from the lower in the middle position, the coupling element 90 is also moved in the direction of the arrow P11 above. Here, the pin is moved within the groove 98 of the stationary second guiding element 100 such that the pin 92 is arranged on the position of the groove 98 on which the first leg 104 and the second leg 106 are connected to each other. Here, the leg 92 is still arranged on the lower end of the oblong hole 94 of the first guiding element 96. As the first guiding element 96 is firmly connected to the base plate 50 of the reverse gear 48, the whole reverse gear 48 is pivoted during a movement of the pin 92 within the groove 98 along the first leg 104 from the operating state shown in
In
By adjusting the gear segment 81 from the middle in the upper position, the coupling element 90 is also moved further in the direction of the arrow P11 upwards, whereby the pin 92 is also moved upwards. In this way, the first end of the pin 92 is moved upwards within the oblong hole 90 of the first guiding element 96. Likewise, the second end of the pin 92, guided within the second leg 106 of the groove 98 of the second guiding element 100, moves in the direction of the end of the second leg 106 which is not connected to the first leg 104. In this way, it is achieved that the reverse gear 48 still remains in the first position and thus the direction of rotation of the third drive roll 30, during the adjustment of the switch 18 from the first in the second switch position, is not reversed relative to the direction of rotation of the other two drive rolls 26, 28.
By the mechanism, described in
The method described in connection with
The cam disk 76 respectively includes a portion on said portions on which the pin 80 is arranged when the gear segment 81 is positioned in the lower, the middle or the upper portion, in which the link 78 has a constant radius and thus a constant distance to the center 86 of the cam disk 76. These portions are also referred to as rest zone. By this rest zone it is achieved that the correct switch position and the correct position of the reverse gear is even adjusted, when the cam disk 76 is rotated a little too far or not as far as intended, e.g. in case of defects of the stepper motor 70. In this way, the functional reliability of the device 10 is increased. As long as the pin is arranged within a rest zone, no adjustment of the gear segment 91 takes place. Thus, in particular fault tolerances of the stepper motor 70 are made up for.
By the guidance of the pin 92 within two links, namely the groove 98 and the oblong hole 94, it is achieved that the reverse gear 48 is only adjusted during adjustment from the first in the third switch position and from the third in the first switch position, but not during adjustment from the first in the second switch position and from the second in the first switch position. In this way, it is achieved that the reverse gear is only adjusted when this is also necessary to reverse the direction of rotation of the third drive roll 30. In this way, it is achieved that less switching operations of the reverse gear 48 are necessary and wear of the reverse gear 48 is reduced. Further, in this way it is achieved that fewer problems arise while the reverse gear 48 is coupled in. In an alternative embodiment of the invention, the switch 18 and the reverse gear 48 can also not be connected to each other, but can respectively be adjusted via separate adjustment units between the individual positions. In particular, the switch 18 and the reverse gear 48 can be respectively adjusted via a proper stepper motor between the individual positions.
Further, in an alternative embodiment of the invention, the reverse gear 48 can also comprise less than five gear wheels 52 to 60 or more than five gear wheels 52 to 60. In particular, the reverse gear 48 can also comprise three gear wheels.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the invention, and all such modifications are intended to be included within the scope of the invention.
