Description

The invention relates to a method for determining the stock of banknotes of a reel memory for receiving banknotes. In the method, notes of value are stored in the roller storage in succession by a winding drum is rotated by means of a motor, so that the notes of value are arranged between film strips wound on the winding drum. Furthermore, the invention relates to a device for receiving notes of value, which comprises a roll storage for receiving notes, which has a winding drum and a motor for rotating the winding drum. Furthermore, the device comprises a memory element for storing data and a control unit for controlling the motor.

In roll storages, the notes of value to be stored on them are taken up between at least two film strips and wound up between the film strips on a winding drum. For this purpose, the winding drum is driven by means of a motor. The motor is controlled in particular by means of light barrier signals, via which the edges of the notes of value are detected, so that it can be determined accordingly when a note has been completely fed or completely removed.

Both in the delivery of notes of value and in the removal of notes of value, it can happen that Unintentionally overlapping notes of value, so that it can not be detected with the help of the light barriers whether one or more notes of value have been added or removed. In particular, with overlapping notes of value, it can not be determined how many notes of value overlap and have thus been removed or supplied. As a result, the current inventory of role repositories in banknotes is unknown. However, since this stock is essential for secure inventory management, it is common to completely physically empty the reel store after the occurrence of a picking or feeding error, thus reestablishing a secured inventory.

The problem with this is that the physical emptying of the roller storage is complicated and time-consuming. Furthermore, it may be necessary for the device in which the roller storage is arranged to be taken out of operation for this time.

From the documents DE 10 2009 026 253 A1 and DE 10 2007 022 558 A1 Roll storage are known in which the drive shaft of the motor is connected via a hysteresis to the film drum.

The document DE 299 23 960 U1 describes a roller storage, the storage and storage coils are driven by a stepper motor. Here, the drive shaft of the motor is connected via a slip clutch with the supply reel.

It is an object of the invention to provide a method for determining the inventory of a reel storage for receiving notes of value on notes of value and a device for holding notes, with the help of a simple way the stock of a reel of notes of value can be reliably determined.

This object is achieved by a method having the features of claim 1 and by a device having the features of the independent device claim. Advantageous developments are specified in the dependent claims.

According to the invention, the current engine position of the engine is determined at least in a part of the notes of value after winding up the note of value, wherein the determined motor position is stored uniquely assigned to the respective value note. To determine the stock of the reel memory on banknotes, the current motor position is determined, for example, in the occurrence of an irregularity when depositing or paying out notes of value. This current engine position is compared with the stored engine positions and, depending on the result of this comparison, the current inventory of the reel memory is determined on notes of value.

This ensures that the current stock can be determined at any time only on the basis of the motor position and the stored data. Thus, in the occurrence of errors, especially with overlapping notes of value during feeding or removal, no physical emptying of the role memory must be done. In particular, must no additional sensors are provided, since all necessary data can already be determined with electronics usually present in reel memories.

The rigid coupling of the drive shaft of the motor with the winding drum ensures that at the same engine position, the winding drum also each have the same position, so that each motor position is unique and immutable to a bill of exchange.

The stock comprises, in particular, that value certificate whose assigned, stored motor position corresponds to the currently determined motor position, as well as all banknotes arranged in the order in which they are registered in front of this value note. In the case of a roll memory, the storage takes place on the principle of first in last out, so that a clear recording order is specified. By comparing the current engine position with the stored engine positions, the value note can be determined which must be taken next, that is, the value note which is arranged immediately before the output of the reel memory. Thus, inevitably all notes of value, which are arranged in front of this note in the order of admission, recorded in the role memory, so that the stock is formed by these notes in total.

In an alternative embodiment of the invention can as inventory of role repository and that value certificate whose associated stored engine position has the smallest difference to the currently determined engine position, and all in the series before this banknote arranged notes of value can be determined. In this way, in comparison with the previously described method, in which the determined motor position has to correspond exactly to one of the stored motor positions, it is achieved that the method leads to the correct result even with minor insignificant deviations. In particular, a maximum value is preset which indicates the maximum permissible deviation between the determined and the stored engine positions. If this maximum difference is exceeded, an error message is output and no inventory is determined.

In a particularly preferred embodiment, the engine position of the engine is determined upon supplying each note of value to the reel memory and stored unambiguously assigned to the value note, if no error, in particular no overlapping of several notes of value to be supplied occurs during the feeding. Thus, it is achieved that the engine position is known from each value note and thus regardless of which note the error occurs, the inventory of the engine position can be determined. In an alternative embodiment, for example, the engine position can be determined and stored only every second value. In this case, it may be that to determine the engine position after an error first a bill of exchange must be removed before on the resulting engine position a corresponding bill of exchange and thus a corresponding inventory can be determined.

In particular, each time a number of steps of the engine is stored as a motor position, which he in relation to a predetermined zero position is adjusted in the respective engine position. Alternatively, a plurality of possible engine positions may be preset, wherein the notes of value are assigned to the respective engine position at which they are recorded.

The respective current engine position is determined in particular by means of an electronics for driving the motor, preferably starting from a motor drive signal. Alternatively, a separate sensor may be provided. The use of the electronics for driving the motor has the advantage that no additional components are necessary and a simple inexpensive construction is achieved.

Furthermore, it is advantageous if the recording sequence in which the notes of value are recorded in the reel store is stored. In particular, a list, a table or a database is provided, in which for each note a record is created, which contains at least the position of the note in the recording order and the corresponding motor position. In addition, additional data, such as its denomination, can be stored for each bank note.

If, when feeding in banknotes of several notes of value, they are overlapped with one another in the reel store, which can be determined, for example, via photoelectric barriers, notes of value are taken from the reel store until a note has been taken from which a motor position has been assigned and stored. As a stock, then in the recording order on this Value certificate determined following notes. In this way, when supplying overlapping notes of value without emptying the reel memory, it can be restored to its inventory in which all notes of value added in overlapping form are removed again. By taking a further note of value and determining the position of the motor after taking out this note of value, an unambiguous assignment can be made via the stored data so that it is again known at which position of the recording sequence one is located.

If an irregularity is detected during the removal of notes of value, for example if light barrier signals show that more than one note has been taken overlapping, so that the current inventory of the reel memory is not known, then banknotes will preferably be taken successively as long as the value of each item is removed determined and compared the determined engine position with the stored engine positions, until at a preset number consecutively removed notes of value, the determined motor position coincides with the stored motor position. In this case, the following value note, as well as all banknotes located further up in the order of admission, are then determined as stock. Thus, the comparison of the engine positions of the removed notes of value with the stored engine positions after the occurrence of overlaps again secure information about the stock can be achieved.

The predetermined number of banknotes is at least two, preferably three, notes of value. The higher the number, the safer it can be assumed that a secured stock has been determined again.

When feeding a note of value, the winding drum is rotated by the motor in particular until it has been determined by means of a sensor, preferably a light barrier, that the banknote is completely recorded. In particular, the trailing edges of the notes of value are detected with the aid of light barriers as an edge change. Subsequently, the winding drum is stopped and the motor position determined and stored associated with the value note. When feeding a plurality of notes of value, the determination of the position of the motor is carried out, in particular during operation, that is to say that the motor is not stopped for this purpose.

A further aspect of the invention relates to a device for receiving notes of value, which comprises a roll store for receiving notes of value, which has a winding drum and a motor for rotating the winding drum. Furthermore, a memory element for storing data and a control unit are provided. The control unit determines the current engine position of the engine at least in some of the notes of value after winding up the note of value. Further, the control unit stores the determined motor position the respective value certificate uniquely assigned in the memory element. To determine the inventory of role repository of notes of value, the control unit determines a current engine position and compares this determined current engine position with the stored Motor positions. Depending on the result of this comparison, the control unit then determines the current inventory. The control unit carries this out, in particular, if irregularities have occurred during the removal or the feeding of notes of value, in particular if it has been determined that notes of value were added or removed in an overlapping manner.

The motor is in particular a brushless DC motor. This DC motor can be designed in particular in the form of a stepper motor. Alternatively, a sensor-controlled brushless DC motor may be used, which includes position sensors, with the aid of the current position of the engine can be detected. Furthermore, sensorless, brushless DC motors can also be used as an alternative, which determine the current position of the motor with the aid of the counter-voltage method. Likewise, a DC motor with clock can be used.

In addition, other stepper motors, that is, stepper motors which are not a brushless DC motor, can be used. Furthermore, other DC motors, so not brushless DC motors can be used.

All of these motors described above have the advantage that their motor position can be determined very accurately.

The drive shaft of the motor is in particular rigidly coupled to the winding drum, so that each motor position clearly a rotational position of the winding drum and thus a bank note can be assigned.

The apparatus for receiving notes of value is in particular an ATM, an automatic cash register system and / or an automatic cash deposit. The roller storage can in this case be permanently installed in the respective device or alternatively be arranged in a removable cashbox. In the latter case, the control unit is, in particular, a control unit of the device and the storage element is a storage element of the cashbox so that the stored information remains even when the cashbox is removed. Alternatively or additionally, the storage can also take place on a storage element of the device.

Alternatively, the device for receiving banknotes may also be only a cashbox per se, which in this case must include its own control unit.

The device may be further developed with the features described in the independent method claim dependent claims or corresponding device features. In particular, the method steps described in the dependent method claims are executed by the control unit of the device by processing preset steps of a data program. Conversely, the method according to claim 1 with the in the dependent device claims mentioned features or corresponding method features are further developed.

Further features and advantages of the invention will become apparent from the following description, which illustrates the invention with reference to embodiments in conjunction with the accompanying figures.

In FIG. 1 a schematic representation of a device 10 for handling banknotes is shown. The device 10 may be, for example, an ATM, an automatic cash register system or an automatic cash deposit.

The device 10 comprises an input and output tray 12 for input and output of notes of value as well as four cash boxes 14 to 20 for receiving notes of value. At the in FIG. 1 In the embodiment shown, the cash box 14 comprises a roll storage 22, on which the notes of value to be received between film strips are wound up on a winding drum. The exact structure of such a reel memory is still in connection with FIG. 3 described in more detail.

The other three cash boxes 16 to 20 are designed such that in them the recorded notes of value are each received as a stack of notes on their edges standing in a receptacle 24. Of course, as an alternative, more money cassettes 14 with a roll storage 22 and fewer cash cassettes 16 to 20 with a receiving compartment 24 can be used. In addition, the device 10 may also include more or fewer than four cash boxes 14 to 20.

The device 10 further has a control unit 26 for controlling the device 10. In addition, the device 10 may also have an unillustrated storage element for storing data. Also, the cash boxes 14 to 20 may include storage elements for storing data with information about the notes of value received therein.

In FIG. 2 is a schematic representation of a device 30 for handling notes of value according to a second embodiment shown. Elements with the same structure or the same function have the same reference numerals.

The device 30 after FIG. 2 differs from the device 10 according to the first embodiment FIG. 1 in that instead of cash cassettes 14 to 20 it comprises four stationary roller storages 22, ie that these roller storages 22 are permanently arranged in the device 30 and are not removed for the purpose of transporting notes of value. Alternatively, the device 30 may also comprise both stationarily arranged roller storages 22 and devices in the form of money cassettes 14 to 20 for receiving notes of value.

The following in conjunction with the FIGS. 4 to 6 described method for determining the existence of a reel memory 22 of notes of value can be used for any type of roll memory 22, regardless of whether this is stationary in a device 10, 30 or in a cash box 14. The individual process steps are in this case in particular by the control unit 26 executed. The storage of the data can take place both in a memory element of the device 10, 30 and the cash boxes 14 or the reel memory 22.

In FIG. 3 a roller storage 22 is shown schematically. The roller storage 22 has a winding drum 40 and a motor 42 for rotating the winding drum 40 in the direction of the double arrow P1. The motor 42 is in particular a brushless DC motor, which is preferably designed in the form of a stepper motor. The motor 42 has a drive shaft, not shown, which is rigidly connected to the winding drum 40. Under the rigid connection is understood in particular that no relative rotation of the drive shaft and the winding drum 40 to each other is possible.

Furthermore, the roller storage 22 has two film supply rolls 44, 46 on which film strips 48, 50 are wound, which are guided over guide rollers 52, 54. A note of value to be received in the reel store 22 is supplied to it in the direction of the arrow P2 in such a way that it is received between the two film strips 48, 50. By turning the winding drum 40 by the motor 42 of the bill of exchange between the film strips 48, 50 recorded wound on the winding drum 40. Here, the individual recorded notes of value are taken in succession, so that a withdrawal of notes of value from the roll memory 22 only on the principle of last in first out is possible.

In FIG. 4 FIG. 3 is a flow chart of a method for receiving bills in the reel store 22. After the process in step S10 has been started, a bill of exchange is fed in step S12, wherein in the feed, in particular, the winding drum 40 is rotated by the motor 42 until the added bill is completely received. Subsequently, the current motor position of the motor 42 is determined in step S14. In particular, the current engine position is determined as a number of steps that the engine 42 must have rotated from a zero position to be located in the current engine position.

Subsequently, in step S12, the determined motor position is assigned to the last recorded value ticket and stored unambiguously assigned to the value ticket in a memory element, not shown. Subsequently, the process is ended in step S18. The individual motor positions are stored in particular in a memory element of the apparatus 10, 30 for handling bank notes, the cash box 14, in which the roller storage 22 is received, or a separate storage element of the reel memory 22. The determination of the position of the motor 42 takes place in particular Help the electronics of the motor 42, wherein the assignment and storage is controlled in particular by the control unit 26.

When feeding notes of value 24 to the roll memory 22, it may happen that banknotes overlap, so that not every note a motor position can be assigned and no scheduled payment of these overlapping notes of value is possible because no clear Lichtschrankensignale to control such a payment are possible , In particular, this also leads to that the inventory of reel memory 22 is not aware of a bank note.

Even when removing notes of value may lead to irregularities, so that even when removing the current inventory of the role memory 22 may be unclear. In both cases, those in the Figures 5 and 6 described method for determining the inventory of the reel memory 22 are executed on notes of value, whereby in a simple way, the current inventory of the reel memory 22 of the bank note after occurrence of an irregularity can be determined again. In particular, both methods have the advantage that no physical emptying of the roller storage 22 is necessary.

After that in FIG. 5 A method according to a first embodiment has been started in step S20, a value note is taken in step S22 and the current motor position of the motor 42 is determined after the removal of the note in step S24.

Subsequently, in step S26, a comparison is made of the current motor position determined in step S24 with the motor positions stored in the memory element. In the subsequent step S28 it is determined whether the current engine position coincides with one of the stored engine positions. If this is the case, the current stock can be determined in step S30 before the method is ended in step S32. Due to the correspondence between the current engine position with one of the stored engine positions, due to the rigid coupling between the motor 42 and the winding drum 40 and Thus, the unique, safe, unchanging relationship between a motor position and winding drum position are determined, which is the next recorded value notes in the recording sequence, which is located in front of the output of the roller storage 22 and thus must be removed next. It is also clear here that all other notes of value arranged in the order in which they are still in front of this banknote are likewise still arranged in the reel store 22, so that the stock can again be ascertained in a secure manner.

On the other hand, if it has been determined in step S28 that there is no match between the detected engine position and the stored engine positions, the inventory can not be determined and an error message is issued in step S34 before the process is terminated in step S32.

In determining the coincidence 28, a smaller tolerance difference may in particular be preset, so that due to environmental influences resulting small deviations between the stored engine position and the actual engine setting does not directly lead to the fact that no assignment is possible, but still a value associated with the engine position and value the stock of notes of value in the reel storage can be determined.

In FIG. 6 1 is a flowchart of a method for determining the inventory of a reel memory 22 on notes of value according to a second embodiment. This procedure differs from that Method according to FIG. 5 in that, if a match has not been determined in step S28, a further bill of exchange is taken from the roller store 22 in step S36 and in step S38 the current motor position of the motor 42 is determined after removal of this further bill of exchange. Subsequently, the method is continued in step S28 in that it is again determined that there is a match between the new current engine position now determined in step S38 and one of the stored engine positions. If this is the case, the inventory can be determined based on the engine position and the procedure can be terminated. If this is still not the case, then the method with steps S36 and S38 is continued again, that is, a further bill of exchange is taken and determines the new motor position after removal of this additional note, before again a comparison between the now new current engine position and the stored engine positions. This is particularly continued until it comes to a match between a determined and a stored engine position, so that the stock can be determined.

Alternatively, a maximum number of maximum value for the investigations may be preset value notes. If no agreement and therefore no stock could be determined even after the removal of the preset maximum number of notes, the method is terminated in particular and an error message is output, so that a manual intervention is unavoidable.

In a further preferred embodiment, the stock can only be assumed to be secure again be if there is a match between each currently determined engine position and the corresponding associated stored engine position for a predetermined number consecutively removed notes of value. This has the advantage that it can be concluded with an even higher security on a secured portfolio, since the random match is the less likely, the more consecutively removed notes each have the appropriate motor position.

The methods described above represent preferred embodiments. It is also possible to omit individual method steps, provided that the inventory of the reel memory 22 is generally determined according to the invention as value notes that a comparison of a current motor position with stored motor positions takes place.
