Description

The present invention relates to technology for processing paper sheets such as banknotes and negotiable securities.

2. Description of the Related Art Conventionally, there is a banknote processing apparatus that identifies the denomination, authenticity, etc. of banknotes that are being transported along a transport path, and transports the banknotes to a transport destination according to the identification result. This type of banknote processing apparatus is used in various types of equipment for handling banknotes, such as automated teller machines (ATMs), ticket vending machines, and fare adjustment machines.

In addition, a configuration has been proposed in which banknote data that satisfies preset conditions is collected (see Patent Literature 1, etc.). This patent document 1 is configured to set, as conditions for collecting data related to banknotes, the identification result of authenticity (discrimination result) of the banknote, the identification result of fitness of the banknote, the denomination of the banknote, and the like.

JP-A-2017-45310

However, Patent Document 1 collects data related to bills for the purpose of improving bill identification performance. For this reason, in the configuration of Patent Document 1, it is not possible to properly collect data for suppressing a decrease in the operation rate of the banknote processing apparatus due to the occurrence of a banknote jam in the transport path.

SUMMARY OF THE INVENTION An object of the present invention is to provide a technique capable of properly collecting useful data for suppressing a decrease in operating rate due to jamming of paper sheets in a conveying path.

In order to achieve the above objects, the paper sheet processing apparatus of the present invention is constructed as follows.

The state acquisition unit acquires the state of the paper sheet that the transport unit is transporting along the transport path. The paper sheets referred to here are banknotes, securities, etc., and the state of the paper sheets includes wrinkles, folds, stains, and the like.

The determination unit determines whether or not the transport speed of the paper sheets in the transport path is appropriate. The output unit outputs the state of the paper sheet acquired by the state acquisition unit for the paper sheet for which the determination unit determines that the transport speed of the paper sheet on the transport path is not appropriate.

In this configuration, by collecting the states of the paper sheets output by the output unit, it is possible to collect the states of the paper sheets in which the conveying speed of the paper sheets in the conveying path was not appropriate. Wrinkles, folds, stains, etc. of paper sheets are the main causes of paper sheets jamming in the conveying path. In addition, the change in the transport speed of paper sheets in the transport path is caused by the frictional force generated on the contact surface between the transport members (transport rollers, transport belts, etc.) and the paper sheets. It is caused by changes due to tearing or the like. Therefore, by collecting the states of paper sheets in which the conveying speed of the paper sheets in the conveying path is not appropriate, it is possible to collect the states of the paper sheets in which the possibility of jamming in the conveying path is not low. That is, according to this configuration, it is possible to appropriately collect useful data for suppressing a decrease in the operating rate due to jamming of paper sheets in the conveying path.

Further, it is preferable that the output unit also outputs the state of the paper sheet that has been jammed in the conveying path, as obtained by the state acquisition unit. With this configuration, it is possible to collect the status of bills that are actually jammed in the transport path.

Further, the output unit may be configured to output the state of the paper sheet in association with the transport speed of the paper sheet in the transport path. With this configuration, the state of the collected paper sheets can be analyzed in more detail.

Further, the paper sheet processing apparatus includes a conveyance operation setting information storage unit that stores conveyance operation setting information in which conveyance operation settings of the paper sheet in the conveyance unit are associated with each state of the paper sheet; A conveying operation setting unit that refers to the conveying operation setting information and sets the conveying operation of the sheet based on the state of the sheet acquired by the state acquiring unit.

In this case, by storing the transport operation setting information in the transport operation setting information storage unit based on the collected analysis result of the state of the paper sheets, it is possible to prevent the paper sheets from jamming in the transport path. That is, it is possible to suppress a decrease in the operation rate of the paper sheet processing apparatus due to the paper sheets being jammed in the conveying path.

According to the present invention, it is possible to appropriately collect useful data for suppressing a decrease in operating rate due to jamming of paper sheets in the conveying path.

It is a block diagram which shows the structure of the principal part of the banknote processing apparatus concerning this example. It is a schematic diagram showing a banknote transport path of the banknote processing apparatus according to this example. It is a figure explaining the determination level with respect to the conveyance speed of a banknote. It is a flowchart which shows operation|movement of a banknote processing apparatus.

A banknote processing apparatus that is an embodiment of the present invention will be described below.

<1. Application example>
The banknote processing apparatus according to this example is applied to ticket vending machines, payment machines, etc., identifies the denomination and authenticity of inserted banknotes, and processes the banknotes according to the identification result. This banknote processing apparatus outputs the acquired banknote status for banknotes that have a relatively high possibility of causing a banknote jam in a transport path for transporting banknotes. In addition, this banknote handling apparatus also outputs the acquired banknote status for banknotes that have actually caused a jam (banknote jam) in the banknote transport path.

The state of each banknote output from the banknote processing device is collected by an analysis device (not shown). The analysis device uses the state of the collected banknotes to analyze factors that cause banknote jams in the banknote transport path, and to consider countermeasures for suppressing the occurrence of banknote jams. In other words, the banknote processing apparatus outputs information (statement of banknotes) that is useful for analyzing factors that cause banknote jams in the banknote transport path, and for considering countermeasures for suppressing the occurrence of banknote jams.

Further, the banknote processing apparatus controls the banknote transport operation based on the results of examination of countermeasures for suppressing the occurrence of banknote jams in the analyzer.

<2. Configuration example>
FIG. 1 is a block diagram showing the configuration of the main part of the banknote processing apparatus according to this example. FIG. 2 is a schematic diagram showing a banknote transport path of the banknote processing apparatus according to this example. The banknote processing apparatus 1 includes a control unit 2 , a banknote transport section 3 , a banknote identification section 4 and an upper input/output section 5 .

The control unit 2 controls the operation of each part of the banknote processing apparatus 1 main body. The control unit 2 also has a conveying speed determining section 2a, a conveying operation setting section 2b, a bill state storage section 2c, and a conveying operation setting information storage section 2d. The details of the transport speed determination unit 2a, the transport operation setting unit 2b, the banknote state storage unit 2c, and the transport operation setting information storage unit 2d will be described later.

The banknote transport unit 3 transports banknotes inserted in the banknote slot 3i along the banknote transport paths 11, 12, and 13. As shown in FIG. As shown in FIG. 2, the banknote transport path 11 connects the banknote insertion port 3i and the banknote return port 3o. The banknote insertion port 3i and the banknote return port 3o are located on the front side of the banknote processing apparatus 1 main body. The banknote transport path 11 is a transport path that makes a U-turn inside the body of the banknote processing apparatus 1 . The banknote transport path 12 is a transport path branched from the banknote transport path 11 at the branch point A shown in FIG. The banknote transport path 12 is used as a holding section for temporarily holding banknotes inserted in the banknote slot 3i. The number of banknotes held in the banknote transport path 12 is not always one. The banknote transport path 12 holds a plurality of banknotes in a piled state. The banknote transport path 13 is a transport path branched from the banknote transport path 12 at the branch point B shown in FIG. One end of the banknote transport path 13 (the end opposite to the branch point B) is connected to the banknote storage cassette 10 . That is, the banknote transport path 13 is a transport path for transporting banknotes stored in the banknote storage cassette 10 .

At the branch point A and the branch point B, a flapper (not shown) for switching the destination of the banknote is provided. The banknote transport unit 3 switches the destination of the banknote by controlling the flapper. Further, the bill transport directions in the bill transport paths 11, 12, and 13 are bidirectional. Specifically, the direction in which the banknotes are conveyed in the banknote transport path 11 can be switched between the direction from the banknote insertion port 3i to the banknote return port 3o and the direction from the banknote return port 3o to the banknote insertion port 3i. Similarly, the direction in which banknotes are conveyed in the banknote conveyance path 12 can be switched between the direction from the branch point A to the branch point B or the direction from the branch point B to the branch point A. Further, the transport direction of banknotes in the banknote transport path 13 can be switched between the direction from the branch point B to the banknote storage cassette 10 or the direction from the banknote storage cassette 10 to the branch point B.

The banknote transport unit 3 switches the transport direction of the banknotes in the banknote transport paths 11 , 12 , and 13 individually. Specifically, the banknote transport unit 3 switches the banknote transport direction in the banknote transport paths 11, 12, and 13 by controlling the rotation direction of a motor (not shown). The banknote transport paths 11, 12, and 13 have, for example, a configuration in which a pair of transport rollers for sandwiching and transporting banknotes are arranged in the transport direction. The bill conveying unit 3 drives the conveying rollers by drive control of a conveying motor (not shown). The banknote transport section 3 also controls the rotation speed of the transport motor.

Further, the banknote transport section 3 detects the presence or absence of banknotes at the detection positions of the photoelectric sensors 3a to 3g arranged at a plurality of positions of the banknote transport paths 11, 12, and 13, respectively. Further, the banknote transport unit 3 acquires the transport speed of the banknotes in the banknote transport paths 11, 12, and 13 using the detection signals of the photoelectric sensors 3a to 3g. Specifically, the time difference between the bill detection timings between the two photoelectric sensors 3a to 3g is measured, and the measured time difference and the distance between the two photoelectric sensors 3a to 3g (the distance on the bill transport path) are used. to obtain the paper money transport speed. Further, the banknote transport unit 3 can control the transport speed of the banknotes in the banknote transport paths 11, 12, and 13 by controlling the rotation speed of a transport motor (not shown). The banknote transport section 3 corresponds to the transport section referred to in the present invention.

Note that the detection of the transport speed of bills is performed by measuring the time from when the bills are detected to when the bills are no longer detected by one of the photoelectric sensors 3a to 3g. You may acquire the conveyance speed of a banknote using length. The length of the bill in the conveying direction is determined by the denomination of the bill.

The bill identification unit 4 identifies the authenticity and denomination of bills conveyed along the bill conveying path 11 . The banknote identification unit 4 has an image sensor 4a for acquiring the optical pattern (image) of the banknote, a magnetic sensor 4b for acquiring the magnetic pattern of the banknote, and the like. The banknote recognition unit 4 also includes a thickness sensor and the like for acquiring the thickness of the banknote (not shown). The banknote identification unit 4 identifies the authenticity, denomination, etc. of the banknote based on information acquired from the banknote by various sensors.

In addition, the banknote recognition unit 4 determines the state of the banknote for each item such as wrinkles, folds, stains, tears, etc. based on the optical pattern of the banknote acquired by the image sensor 4a, the magnetic pattern of the banknote acquired by the magnetic sensor 4b, and the like. to get The states of wrinkled, folded, soiled, torn bills, etc. correspond to the states of paper sheets referred to in the present invention. The banknote identification unit 4 corresponds to the state acquisition unit referred to in the present invention.

The host input/output unit 5 is an interface for inputting and outputting data with host devices such as ticket vending machines and payment machines to which the banknote processing apparatus 1 is applied. The upper input/output unit 5 corresponds to the output unit referred to in the present invention.

Next, the conveying speed determining section 2a, the conveying operation setting section 2b, the banknote state storing section 2c, and the conveying operation setting information storing section 2d which the control unit 2 has will be described. The transport speed determination unit 2a determines whether the transport speed of the banknotes in the banknote transport paths 11, 12, and 13 is appropriate. As described above, the banknote transport unit 3 acquires the transport speed of the banknotes in the banknote transport paths 11 , 12 , and 13 . The transport speed determination unit 2a determines to which range of determination levels L0 to L4 shown in FIG. 3 the transport speed of the banknote acquired by the banknote transport unit 3 belongs. At the determination level L0, the transport speed is in the range of va to vb, and is a level at which it is determined that the bill transport speed is appropriate. Determination level L1 is a speed higher than va, and is a level at which it is determined that the bill transport speed is not appropriate and is fast. Determination level L2 is a level at which the transport speed is in the range of vc to vb, and is determined to be inappropriate and somewhat slow. At the determination level L3, the conveying speed is in the range of vd to vc, and is a level at which it is determined that the bill conveying speed is not proper and is slow. Determination level L4 is a speed lower than vd, and is a level at which it is determined that the bill transport speed is not appropriate and is considerably slow. The conveying speed determination section 2a corresponds to the determination section according to the present invention.

The transport operation setting unit 2b sets the transport speed and transport route of the banknotes in the banknote transport paths 11, 12, and 13. FIG. The transport operation setting unit 2b sets the transport speed and the transport route of the banknote based on the transport operation setting information stored in the transport operation setting information storage unit 2d, which will be described later.

The banknote status storage unit 2c stores banknote-related data in which the date and time of insertion, the denomination, the determination level of the transport speed, the presence or absence of banknote jamming, the banknote image, the banknote status, etc., are associated with the banknotes inserted in the banknote slot 3i. memorize The state of bills includes wrinkles, creases, stains, tears, and the like. The banknote identification unit 4 acquires the denomination of the banknote, the banknote image, and the state of the banknote. The conveying speed determination unit 2a determines the determination level of the bill conveying speed. Further, whether or not a banknote jam has occurred is detected in the banknote conveying unit 3 .

The control unit 2 has a clock function for measuring the current date and time, and is configured to be able to detect the time when a banknote is inserted into the banknote slot 3i. Also, the bill-related data may be missing some of the items described above, or may be added with other items.

The transport operation setting information storage unit 2d stores transport operation setting information in which the rotational speed of the transport motor and the transport route are associated with each denomination and each bill state. For example, if there are four banknote states: wrinkles, creases, stains, and tears, and the states of each item are classified into three levels, the transport operation setting information is the sum of the banknotes of each denomination. 81 patterns are associated with the rotation speed of the transport motor and the transport route. This transport operation setting information is generated based on the results of examination of countermeasures for suppressing the occurrence of banknote jams in the analysis device described above.

Note that even if the rotational speeds of the transport motors are the same, the transport speed of the banknotes on the banknote transport path is not necessarily the same. That is, even if the rotation speed of the transport motor is the same, the frictional force generated on the contact surface between the transport roller and the banknote changes due to wrinkles, folds, stains, tears, etc. of the banknote. may not be the same.

The control unit 2 of the banknote handling machine 1 is composed of a hardware CPU, memory, and other electronic circuits. When the hardware CPU executes the sheet processing program according to the present invention, it operates as the conveying speed determining section 2a and the conveying operation setting section 2b. The memory also has an area for developing the paper sheet processing program according to the present invention and an area for temporarily storing data generated during execution of this program. This memory also has areas used as a bill state storage section 2c and a transport operation setting information storage section 2d. The banknote state storage unit 2c and the transport operation setting information storage unit 2d are configured by storage elements or storage media (nonvolatile memory, volatile memory, hard disk, solid state drive, etc.) connected to the control unit 2. good too. Also, the control unit 2 may be an LSI that integrates a hardware CPU, memory, and the like. Also, the hardware CPU is a computer that executes the paper sheet processing method according to the present invention.

<3. Operation example>
First, with reference to FIG. 2, a brief description will be given of the banknote transport path in the banknote processing apparatus 1 during normal operation. This banknote processing apparatus 1 conveys banknotes inserted into a banknote slot 3i along a banknote transport path 11, and a banknote identification unit 4 identifies the authenticity and denomination of the banknote. Bills whose authenticity or denomination cannot be identified by the bill identification unit 4 are conveyed along the bill conveying path 11 and discharged to the bill return port 3o. A banknote whose authenticity and denomination have been identified by the banknote identification unit 4 is conveyed along a banknote conveying path 11, sent to a banknote conveying path 12 at a branch point A, and temporarily held in the banknote conveying path 12. . As described above, the banknote transport path 12 may hold a plurality of banknotes in a piled state. When the end of the transaction is notified from the host device, the banknote processing apparatus 1 sends the banknotes held in the banknote transport path 12 to the banknote transport path 13 at the branch point B and stores them in the banknote storage cassette 10 .

Although the details will be described later, the banknote processing apparatus 1 may discharge banknotes whose authenticity and denomination have been identified by the banknote identification unit 4 to the banknote return port 3o. In addition, the banknote processing apparatus 1 allows banknotes, whose authenticity and denomination have been identified by the banknote identification unit 4, to be processed on the banknote transport path 12 even before the end of the transaction is notified from the host device. In some cases, the banknotes are stored in the banknote storage cassette 10 without being temporarily reserved.

Note that the banknote processing apparatus 1 according to this example is configured to store banknotes inserted into the banknote insertion slot 3i in the banknote storage cassette 10 as described above. It is configured so that it is not discharged to the banknote return port 3o (or the banknote insertion port 3i) as change or the like.

FIG. 4 is a flow chart showing the operation of the banknote processing apparatus according to this example. The banknote processing apparatus 1 waits for the start of transaction to be input from the host device to the host input/output unit 5 (s1). In the banknote processing apparatus 1, when the start of transaction is input from the host device to the host input/output unit 5, the banknote is inserted into the banknote slot 3i, or the end of the transaction is entered from the host device to the host input/output unit 5. waits for it to be done (s2, s3).

When the banknote processing apparatus 1 detects that a banknote has been inserted into the banknote slot 3i in s2, it starts transporting the currently inserted banknote (s4). The banknote identification unit 4 identifies the authenticity and denomination of the banknotes that have started to be transported in s4, and acquires the state of the banknotes. In addition, the banknote transport unit 3 acquires the transport speed of the banknote that has started transporting in s4.

The banknote processing apparatus 1 stores the banknote-related data based on the banknote status acquired by the banknote identification unit 4 in the banknote status storage unit 2c (s5). Further, the transport operation setting unit 2b determines the transport path of the banknote and the rotation speed of the transport motor based on the state of the banknote acquired by the banknote recognition unit 4 (s6). At s6, any one of the transport route for temporarily holding the banknotes in the banknote transport path 12, the transport route for storing the banknotes in the banknote storage cassette 10, or the transport route for discharging the banknotes to the banknote return port 3o is determined. At s6, the transport operation setting unit 2b selects the rotational speed of the transport motor corresponding to the state of the banknote acquired by the banknote recognition unit 4 from among the transport operation setting information stored in the transport operation setting information storage unit 2d. and the transport path of the banknote are read, and the rotation speed of the transport motor read here and the transport path are determined.

As described above, the transport operation setting information is generated based on the results of examination of countermeasures for suppressing banknote jams in the analyzer. A supplementary description of the transport operation setting information will be provided. The analyzer classifies, for example, the states of banknotes into the following four events (a) to (d).
(a) The possibility of bill jams occurring in the normal transport motor rotation speed and the normal transport path is low. (c) By lowering the rotation speed of the transport motor, the possibility of banknote jamming can be reduced. (d) Even if the rotational speed of the conveying motor is reduced, the possibility of banknote jamming cannot be reduced.
Associating the normal rotation speed of the transport motor and the normal transport path with the state of the banknotes classified in (a) above,
Associating the state of the banknotes classified in (b) above with the rotation speed of the transport motor, which is lower than the normal speed, and the normal transport route,
The state of the banknotes classified in (c) above is associated with the rotational speed of the transport motor that is lower than normal and the transport path for storing the banknotes in the banknote storage cassette 10 without temporarily holding them in the banknote transport path 12,
Corresponding to the states of the banknotes classified in (d) above, the rotation speed of the transport motor, which is lower than usual, and the transport path for discharging to the banknote return port 3o,
Then, the transport operation setting information is generated.

Note that the transport operation setting information may be created by other methods than the method described above. Moreover, in the above example, only the case of classifying the state of banknotes into four events is taken as an example, and the number of events to be classified may be any number.

The banknote processing apparatus 1 stores the transport operation setting information generated by the analysis device in the transport operation setting information storage unit 2d.

The banknote transport unit 3 transports the currently inserted banknote at the rotation speed of the transport motor and the banknote transport route determined in s6. The transport speed determination unit 2a determines whether the transport speed of the banknotes in the banknote transport paths 11, 12, and 13 is appropriate (s7). Further, the banknote processing apparatus 1 determines whether the banknote transport operation determined in s6 is normal transport (normal transport motor rotation speed and normal transport route) (s8). If it is determined in s7 that the bill transport speed is not appropriate, or if it is determined in s8 that the banknote transport operation is not normal transport, the bill processing apparatus 1 turns on the output flag (s9).

When the banknote transport unit 3 completes the transport of the banknotes, the banknote processing apparatus 1 stops the banknote transport operation (s10, s11) and returns to s2.

Further, when receiving an input from the host device to end the transaction, the banknote processing apparatus conveys and stores the banknotes temporarily held in the banknote transport path 12 to the banknote storage cassette 10 (s12). If the output flag is turned on, the banknote processing apparatus 1 outputs the banknote-related data stored in s5 to the host device (s13, s14), and deletes the banknote-related data stored in the banknote state storage unit 2c. (s15) and return to s1. If the output flag is not turned on, the banknote processing apparatus 1 deletes the banknote related data stored in the banknote state storage unit 2c in s15, and returns to s1. In s15, the output flag is also reset (turned off).

Also, although not particularly shown in FIG. 4, the banknote processing apparatus 1 executes the processing from s14 onward when a banknote jam occurs. That is, when a bill jam occurs, the bill processing apparatus 1 outputs the bill-related data stored in the bill state storage unit 2c to the host device at that time.

In this manner, the banknote processing apparatus 1 according to this example temporarily stores banknote-related data related to banknotes processed in the transaction in the banknote state storage unit 2c for each transaction. The banknote processing apparatus 1 does not output the banknote-related data temporarily stored in the banknote state storage unit 2c to the host device for transactions in which only banknotes with a low possibility of banknote jamming are processed. In other words, the banknote processing apparatus 1 outputs the banknote-related data temporarily stored in the banknote state storage unit 2c to the higher-level device for transactions in which banknotes that are not likely to cause banknote jams are processed. In other words, the banknote processing apparatus 1 outputs to the host device data that is useful for considering countermeasures for suppressing a decrease in operating rate due to banknote jamming in the transport path.

Note that the host device may be configured to transmit the banknote-related data acquired from the banknote processing device 1 at appropriate timing to the analysis device. The banknote-related data thus obtained may be copied to a storage medium (hard disk, SSD, USB memory, CD, etc.), and the banknote-related data copied to this storage medium may be read by the analyzer.

<4. Variation>
In the above description, the banknote handling apparatus 1 configured to insert banknotes one by one into the banknote slot 3i has been described as an example. It may be a configuration having.

Moreover, the banknote processing apparatus 1 may be configured to have a banknote storage cassette for deposit and a banknote storage cassette for withdrawal. In this case, the banknotes stored in the dispensing banknote storage cassette can be released as change or the like. Further, the banknote processing apparatus 1 may be configured such that banknote storage cassettes are provided for each denomination and deposited banknotes are used as dispensed banknotes.

In the above description, the banknote processing apparatus 1 for processing banknotes was described as an example, but the paper sheet processing apparatus may be configured to handle securities such as checks and bills.

Further, in the above example, in a transaction in which banknotes that are not likely to cause a banknote jam are processed, banknote-related data for all banknotes processed in this transaction is output to the host device. Only banknotes for which the possibility of jamming is not low may be configured such that banknote-related data relating to those banknotes is output to the host device. However, when a banknote jam occurs, it is preferable to output the banknote-related data stored in the banknote state storage unit 2c to the host device as in the above example.
