DETAILED DESCRIPTION

[0034] FIG. 1 is a schematic illustration of a device 10 for handling notes of value. The device 10 is in particular an automated teller safe, an automatic POS system and/or an automated teller machine, such as a deposit machine for depositing banknotes and checks.

[0035] The device 10 comprises a head module 12 and a safe 14. Four value note cassettes 16a to 16d are arranged in the safe 14, in which the notes of value can be accommodated. In particular, one of the value note cassettes 16a to 16d is provided for receiving checks and the other three value note cassettes 16a to 16d are provided for receiving banknotes. The banknotes are accommodated in particular by type, i.e. only banknotes of one denomination are accommodated in one value note cassette 16a to 16d. Alternatively, mixed storage is also possible, i.e. notes of value of different denominations are mixed in one value note cassette 16a to 16d. In an alternative embodiment, also more than four or less than four, in particular two, value note cassettes 16a to 16d can be provided in the safe 14. In particular, a so-called reject cassette can be provided, in which notes of value that are suspected of being counterfeit and/or show damage are held. In a preferred embodiment, two value note cassettes 16a to 16d are provided, namely one for holding checks and one for holding banknotes.

[0036] The notes of value can be stored in the value note cassettes 16a to 16d both in stacked form in a receiving area and wound up between two film strips on a roll storage device. Different types of value note cassettes may also be used within the safe 14.

[0037] In the present embodiment, the device 10 may be designed as a depositonly device in which notes of value may only be received. Alternatively, it may be designed as a recycling device in which both notes of value can be input and notes of value can be output.

[0038] The head module 12 has an input and output unit 36, via which the notes of value can be input in the form of a value note stack. Furthermore, this input and output unit 36 can also be used to output individual notes of value and/or value note stacks to the operator of the device 10. In particular, the input and output unit 36 has a so-called shutter 38, via which an opening for feeding and outputting the notes of value can be opened and closed.

[0039] The safe 14 has a transfer slot 18 through which the notes of value are fed from the head module 12 to the safe 14. From the transfer slot 18, the notes of value are transported to the value note cassettes 16a to 16d via a transport path identified by the reference sign 22. The transport path 22 is formed by several transport units 24 to 28.

[0040] The head module 12 further comprises a control unit for controlling the components of the device 10, in particular for controlling drive units of the transport units 24 to 28: Furthermore, the head module 12 comprises an output unit 32 connected to the control unit 30, which output unit serves in particular for displaying information, and an input unit 34, which serves in particular for inputting information. The input unit 34 and the output unit 32 serve as a human-machine interface.

[0041] FIG. 2 shows a side view of the transport unit 24 for transporting notes of value of the device 10 according to FIG. 1.

[0042] The transport unit 24 comprises a first driven idler pulley 40 and a second non-driven idler pulley 42 around which a circulating transport belt 44 is guided for transporting notes of value not shown. FIG. 2 schematically shows a drive unit 55 to drive the first driven idler pulley 40. The transport unit 24 further comprises a plurality of freely rotating guide rollers 46 to 56 which contact the inner side of the circulating belt 44, and freely rotating guide rollers 58 to 62 which contact the outer side of the endless belt 44 at least when no notes of value are being transported in the transport path 22 formed by the belt 44 and the guide rollers 58 to 62 and by guide elements 64, 66. The transport unit 24 has a frame comprising the guide elements 64, 66. Depending on the arrangement of the guide rollers 58 to 62 in the receiving openings 68 to 72 provided in the frame of the transport unit 24, the guide rollers 58 to 62 only contact the outer circumferential surface of the belt 44 or tension the belt 44 by corresponding deflection of the belt 44. In the arrangement of the guide rollers 58 to 62 shown in FIG. 2, the guide rollers 58 to 62 deflect the belt 44 towards the inner space enclosed by the belt 44 by contact of the guide rollers 58 to 62 on the outer surface of the belt 44, so that the belt 44 is tensioned. As a result of the deflection of the belt 44, the belt 44 is forced by the guide roller 58 into the region between the guide rollers 46 and 48, by the guide roller 60 into the region between the guide rollers 48 and 50 and by the guide roller 62 into the region between the guide rollers 54 and 56 so that the angle of wrap of the belt 44 is increased for both the inner guide rollers 46, 48, 50, 54, 56 and the outer guide rollers 58, 60, 62.

[0043] The transport unit 24 further comprises a first removal unit 74 for removing notes of value from the cassette 16d, and a removal unit 76 for removing notes of value from the cassette 16c.

[0044] If, in other embodiments, only notes of value are to be deposited with the aid of the device 10, the units 74, 76 are designed as feed units and, if the device 10 is designed as a recycling device for depositing notes of value and for dispensing these notes of value again, they are designed as feed and withdrawal units for feeding notes of value into the respective cassette 16c, 16d and for withdrawing notes of value from the respective cassette 16c, 16d.

[0045] FIG. 3 shows a first section of the transport unit 24 according to FIG. 2, in which the guide rollers 54, 56, 62 and the belt 44 are shown. The guide rollers 58 to 62 each have a roller element freely rotatable on an axle element, wherein an axle end of the axle element projecting laterally from the roller element serves as a connecting area. The roller elements are arranged in particular on the axle element so as not to be axially displaceable. The axle ends are designed such that they can be inserted into the receiving openings 68 to 72 of the frame of the transport unit 24 both in the position shown in FIGS. 2 and 3 and in a position rotated by 180° about an axis of rotation 78 of the roller 62. In a first position, the axis 78 is a first orthogonal distance to a plane 53 (referenced in FIG. 2) in which the axes of rotation of the idler pulleys 40 and 42 run. In the position rotated by 180°, a second position, the axis of rotation 78 is arranged further away from the belt 44, a second orthogonal distance from the plane 53, so that the circumferential surface of the guide roller 62 is also arranged further away from the axes of rotation 80, 82 of the guide rollers 54, 56. As a result, the guide roller 62 does not press the belt 44 into the area between the guide rollers 54, 56, as a result whereof the belt 44 is less tensioned.

[0046] FIG. 4 shows a second section of the transport unit according to FIG. 2, wherein the guide roller 62 is shown in a perspective view without the belt 44. In FIG. 4, it is clearly visible that the connecting areas of the guide roller 62 formed by the axle ends 84, 86 are arranged in the receiving areas 72, 88. The guide roller 62 can be removed from the receiving areas 72, 88. The connecting areas, i.e. the axle ends 84, 86, can then be rotated together by 180° and then reinserted in the receiving openings 72, 88, the guide roller 62 then being arranged deeper in the guide element 66, so that the circumferential surface of the guide roller 62 then only contacts the outer circumferential surface of the belt 44 and no longer tensions the belt 44. Each of the guide rollers 58 to 62 can be arranged either in the position shown in FIG. 2, in which the respective guide roller 58 to 62 tensions the belt 44, or in a position with the connecting areas rotated by 180, in which it merely contacts the belt 44. In this way, a total of four different belt tensions can be realized with the three guide rollers 58 to 62.

[0047] FIG. 5 shows a sectional view of the guide roller 62. The structure of the guide roller 62 corresponds to the structure of the guide rollers 58, 60. A roller element 96 is freely rotatably arranged on an axle element 98, the axle element 98 being composed of two axle element parts 89, 90. A shoulder 92, 94 is formed in each of the axle element parts 89, 90, by means of which axial displacement of the roller element 96 is prevented. To assemble the guide roller 62, the axle element parts 89, 90 are each inserted into the hollow roller element 96 from one side and preferably connected to one another. Alternatively, the axle element parts 89, 90 can also only be loosely inserted into one another and, after being received in the receiving openings 72, 88, held in these openings such that they cannot move out of the roller element 96 in the direction of the axis of rotation 78.

[0048] One axle end 84, 86 of each of the axle element parts 89, 90 protrudes laterally from the roller element 96. The axle ends 84, 86 each form a connecting area of the axle element 98.

[0049] The connecting areas 84, 86 are designed such that they can be inserted into the receiving openings 72, 88 both in the position shown in FIGS. 2 to 5 and in a position rotated by 180° about the axis of rotation 78 as shown in FIG. 6.

[0050] In FIG. 7, a side view of the transport unit 24 is shown, wherein guide rollers 100, 102, 104 known from the prior art are inserted into the receiving openings 68 to 72, which guide rollers can be removed from the receiving openings 68, 70, 72 in the direction of the arrows P1, P2 and P3 and replaced by the guide rollers 58, 60, 62 in order to increase the belt tension of the belt 44, as shown in FIG. 2.

[0051] FIG. 8 shows a schematic illustration of altogether four contact positions of guide rollers 62, 106, which can be inserted, for example, into the receiving openings 72, 88. In variant 4, the guide roller 62 is arranged in the position shown in FIG. 6, in which the guide roller 62 merely contacts the belt 44, and in variant 2, in the position shown in FIGS. 2, 3 and 5, in which it tensions the belt 44. The guide roller 62 can be exchanged for another guide roller 106 with a larger outer diameter, as shown in variants 1 and 3. In variant 3, the guide roller 106 tensions the belt 44 in contrast to variant 4, but not as strongly as in variant 2. If the position of the guide roller 106 is changed by rotating the connecting areas of the guide roller 106 by 180°, the belt 44 is tensioned more strongly than in variants 2 and 3. With the aid of the two guide rollers 62, 106, the position of which can be changed in each case, there are thus a total of four different height levels L1 to L4, so that four tensioning states of the belt 44 can be produced.

[0052] The position of the axis of rotation is shifted by the amount Δx in variants 3 and 4 compared to variants 1 and 2.

[0053] FIG. 9 shows the schematic arrangement of three guide rollers and a belt in a first position according to variant 3 as shown in FIG. 8. Guide rollers 54, 56 and 106 as well as the belt 44 have been selected as examples. In the position of the guide rollers 54, 56, 106 relative to each other shown in FIG. 9, the belt 44 has a contact area 110 with the guide roller 54, a contact area 112 with the guide roller 56 and a contact area 114 with the guide roller 106.

[0054] FIG. 10 shows a schematic illustration of the three rollers 54, 56, 106 and the belt 44 according to FIG. 9, in which the guide roller 106 is arranged in the variant 1 shown in FIG. 8, so that the belt 44 is further tensioned compared to FIG. 9. This also increases a contact area 110a to the guide roller 54 greater than contact area 110, a contact area 112a to the guide roller 56 greater than the contact area 112, and a contact area 114a to the guide roller 106 greater than the contact area 114, which also increases the wrap angles of the respective rollers 54, 56, 106.
