Description

  The technology disclosed herein relates to a paper sheet processing technology.

  Conventionally, a paper sheet processing apparatus that processes paper sheets such as banknotes and valuable media is known. Further, it is known that in such a paper sheet processing apparatus, a paper sheet bundle is generated from a predetermined number of paper sheets and stored in a bundle storage unit. For example, Patent Document 1 discloses a banknote processing apparatus including a binding unit (a bundle generation unit) that generates a banknote bundle from a predetermined number of banknotes fed out from a denomination cassette.

  By the way, in the paper sheet processing apparatus such as the banknote processing apparatus of Patent Document 1, in order to prevent the occurrence of overflow in the bundle storage unit, the upper limit storage bundle number (which can be stored in the bundle storage unit) with respect to the bundle storage unit When the number of bundles of paper sheets stored in the bundle storage unit reaches the maximum number of stored bundles, the generation of the sheet bundles in the bundle generation unit ends. Thus, it is conceivable to control the operation of the paper sheet processing apparatus. However, the bundle thickness of the paper sheet bundle varies depending on the state of the paper sheets constituting the paper sheet bundle. For example, the bundle thickness of a banknote bundle (an example of a paper sheet bundle) constituted by banknotes (circulation tickets) having a relatively long circulation period is a banknote constituted by banknotes (new tickets) having a relatively short circulation period. It tends to be thicker than the bundle thickness. Accordingly, the number of bundles of paper sheets that can be stored in the bundle storage unit varies depending on the state of the paper sheet bundles. For this reason, sheet bundles in various states (especially thickness) are stored in the bundle storage unit, so it is difficult to set the upper limit storage bundle number appropriately, and the operation of the sheet processing apparatus is reduced. It is difficult to control properly.

  Further, in the paper sheet processing apparatus such as the banknote processing apparatus of Patent Document 1, a sensor for detecting the full state of the bundle storage unit (the state in which the bundle storage unit is full of paper sheet bundles) is provided. It may be possible to control the operation of the sheet processing apparatus so that the generation of the sheet bundle in the bundle generation unit is completed when the full state of the bundle storage unit is detected by the sensor. However, if generation of a sheet bundle is stopped in the bundle generation unit and a sheet bundle in the middle of conveyance remains on the conveyance path between the bundle generation unit and the bundle storage unit, Sheet bundle may be conveyed to the bundle storage unit and overflow may occur in the bundle storage unit. Therefore, after one sheet bundle generated in the bundle generation unit is conveyed from the bundle generation unit to the bundle storage unit and stored therein, generation of the next sheet bundle is started in the bundle generation unit. However, it is conceivable to control the operation of the paper sheet processing apparatus. With such control, it is difficult to shorten the processing time for generating the paper sheet bundle and storing it in the bundle storage unit. .

  Therefore, the technology disclosed herein is a sheet processing apparatus that is not affected by a change in the number of stored bundles (the number of banknote bundles stored in the bundle storage unit) due to a change in the bundle thickness of the sheet bundle.

Each part of the apparatus 10 is controlled. Then, the control unit 80 collects when the number of banknotes stored in the banknote storage unit 26 is less than a predetermined collection end number (or when the number of banknote bundles stored in the bundle storage unit 50 is predetermined). When the number of end bundles is reached), each part of the banknote handling apparatus 10 is controlled so that the collection process is completed in the banknote handling apparatus 10.

  In this example, the control unit 80 determines that the number of banknote bundles stored in the bundle storage unit 50 before the number of banknotes stored in the banknote storage unit 26 falls below the collection end number (or the number of banknote bundles stored in the bundle storage unit 50 is the collection end bundle number. Even before the arrival), when the total bundle thickness of the banknote bundles stored in the bundle storage unit 50 reaches a predetermined bundle thickness threshold (specifically, a third bundle thickness threshold TH3 described later) Each part of the banknote processing apparatus 10 is controlled so that the generation of the banknote bundle is stopped in the bundle generation unit 30 and the collection process is completed. This control will be described in detail later.

[Control in collection processing]
In the collection process, the control unit 80 transports the banknotes stored in the banknote storage unit 26 (or banknotes inserted into the insertion unit 22 and banknotes stored in the banknote temporary storage unit 25) to the bundle generation unit 30. In this manner, the bill storage unit 26 (or the insertion unit 22 and the bill temporary storage unit 25) and the bill transport unit 27 are controlled. Further, in the collection process, the control unit 80 is scheduled to be fed out from the bundle generation unit 30 according to the total bundle thickness of the banknote bundles stored in the bundle storage unit 50 (hereinafter referred to as “total bundle thickness”). The operation of the banknote processing apparatus 10 (particularly, so that the total number of banknote bundles being conveyed and the total number of banknote bundles being conveyed to the bundle conveyance unit 60 (hereinafter referred to as “the number of conveyance bundles”) changes stepwise. The operation of the bundle generating unit 30 and the bundle conveying unit 60 is controlled. Specifically, the control unit 80 performs the following operation.

  The control unit 80 controls the operation of the banknote processing apparatus 10 so that the number of transport bundles becomes a predetermined first transport bundle number when the total bundle thickness of the banknote bundles is lower than the first bundle thickness threshold TH1.

  In addition, the control unit 80 determines the number of transported bundles when the total bundle thickness of the banknote bundles is equal to or greater than the first bundle thickness threshold value TH1 and falls below a predetermined second bundle thickness threshold value TH2. The operation of the banknote handling apparatus 10 is controlled so that the number of bundles is reached. The second bundle thickness threshold value TH2 is set to a bundle thickness that is thicker than the first bundle thickness threshold value TH1. The number of second transport bundles is set to be smaller than the number of first transport bundles.

  In addition, the control unit 80 performs the third conveyance in which the number of conveyance bundles is predetermined when the total bundle thickness of the banknote bundles is equal to or greater than the second bundle thickness threshold TH2 and is lower than the predetermined third bundle thickness threshold TH3. The operation of the banknote handling apparatus 10 is controlled so that the number of bundles is reached. The third bundle thickness threshold value TH3 is set to a bundle thickness that is thicker than the second bundle thickness threshold value TH2. The third transport bundle number is set to a smaller bundle number than the second transport bundle number.

  And the control part 80 controls operation | movement of the banknote processing apparatus 10 to stop the production | generation of a banknote bundle, when the total bundle thickness of a banknote bundle is more than 3rd bundle thickness threshold value TH3.

(Control of bundle generator)
In this example, the control unit 80 is configured to control the operation of the bundle generation unit 30 by controlling the conveyance of the banknotes to the bundle generation unit 30 by the banknote conveyance unit 27. Specifically, the control unit 80 causes the bundle generation unit 30 to start generating a banknote bundle by controlling the banknote conveyance unit 27 so that the banknotes are conveyed to the bundle generation unit 30. Further, the control unit 80 conveys banknotes such that a predetermined number (for example, 100) of banknotes is stacked on the banknote stacking unit 31 at a desired cycle (a cycle in which the number of transported bundles becomes a desired number of transported bundles). By controlling the unit 27, the number of transported bundles (the total number of banknote bundles to be fed out from the bundle generating unit 30 and the total number of banknote bundles transported to the bundle transporting unit 60) is controlled. And the control part 80 stops the production | generation of the banknote bundle by the bundle production | generation part 30 by controlling the banknote conveyance part 27 so that a banknote is not conveyed by the bundle production | generation part 30. FIG.

  The control unit 80 controls the bundling unit 32 so that the timing at which the banknote bundle is generated in the bundling unit 32 has a desired period (a period in which the number of conveyance bundles becomes the desired number of conveyance bundles). The number may be controlled.

[Bundle thickness threshold and number of transported bundles]
Next, referring to FIG. 4, the bundle thickness thresholds (first bundle thickness threshold TH1, second bundle thickness threshold TH2, and third bundle thickness threshold TH3) and the number of conveyance bundles (first conveyance bundle number and second conveyance number). The number of bundles and the number of third conveyance bundles) will be described.

  In FIG. 4, the reference bundle thickness RT is a predetermined bundle thickness of banknote bundles (reference bundle thickness). In this example, the reference bundle thickness RT is set to an assumed value of the bundle thickness of a banknote bundle constituted by a predetermined number of circulation tickets (banknotes having a relatively long circulation period). The thickness of the circulation ticket tends to be thicker than the thickness of the banknote (new ticket) whose distribution period is relatively short, and the bundle thickness of the banknote bundle constituted by the predetermined number of circulation tickets is the predetermined number of new banknotes. It tends to be thicker than the bundle thickness of banknote bundles constituted by tickets. That is, the reference bundle thickness RT is set to be thicker than the bundle thickness of the banknote bundle constituted by a predetermined number of new tickets.

  FIG. 4 illustrates a case where seven new tickets are stored in the bundle storage unit 50. That is, in the example of FIG. 4, the bundle thickness BT of the banknote bundle stored in the bundle storage unit 50 is a bundle thickness that is thinner than the reference bundle thickness RT.

<First bundle thickness threshold>
The first bundle thickness threshold value TH1 is set to a bundle thickness obtained by multiplying the reference bundle thickness RT by a predetermined first storage bundle number. In this example, the first storage bundle number is set to “2”.

<Second bundle thickness threshold>
The second bundle thickness threshold TH2 is set to a bundle thickness obtained by multiplying the reference bundle thickness RT by a predetermined second storage bundle number. The second number of stored bundles is set to be larger than the number of first stored bundles. In this example, the second storage bundle number is set to “7”.

<Third bundle thickness threshold>
The third bundle thickness threshold TH3 is set to a bundle thickness obtained by multiplying the reference bundle thickness RT by a predetermined third storage bundle number. The number of third storage bundles is set to be larger than the number of second storage bundles. In this example, the third storage bundle number is set to “9”.

<First transport bundle number>
The first transport bundle number is less than or equal to the bundle number obtained by subtracting the first storage bundle number from the second storage bundle number. In this example, the first storage bundle number is set to “2”, and the second storage bundle number is set to “7”. The first transport bundle number is set to “4”.

<Second transport bundle number>
The second transport bundle number is smaller than or equal to the bundle number obtained by subtracting the second storage bundle number from the third storage bundle number. In this example, the second storage bundle number is set to “7”, and the third storage bundle number is set to “9”. The second transport bundle number is set to “2”.

<Third transport bundle>
The number of third transport bundles is less than or equal to the number of bundles obtained by subtracting the third storage bundle number from the upper limit storage bundle number predetermined for the bundle storage unit 50. In this example, the upper limit storage bundle number in the bundle storage unit 50 is set to “10”, and the third storage bundle number is set to “9”. The third transport bundle number is set to “1”.

[Details of bundle storage unit]
Next, the configuration of the bundle storage unit 50 will be described in detail with reference to FIG. The bundle storage unit 50 includes an elevating stage 51, a passage sensor 52, a first sensor 81, a second sensor 82, and a third sensor 83.

<Elevating stage and passing sensor>
The elevating stage 51 is configured to move up and down with a banknote bundle placed thereon. The passage sensor 52 is the uppermost surface of the banknote bundle placed on the lifting / lowering stage 51 (when one banknote bundle is placed, the upper face of the banknote bundle, when a plurality of banknote bundles are placed, It is configured to detect that the upper surface of the uppermost banknote bundle has passed a predetermined storage upper limit position (position “0” in FIG. 4) with respect to the bundle storage unit 50.

  And the raising / lowering stage 51 descend | falls so that the uppermost surface of the mounted banknote bundle may become a storage upper limit position, when a banknote bundle is mounted. Specifically, the raising / lowering stage 51 starts to descend when a banknote bundle is placed, and is detected by the passage sensor 52 (the uppermost surface of the banknote bundle placed on the raising / lowering stage 51 has reached the storage upper limit position. In response to the detection).

<First sensor>
The first sensor 81 is configured to detect that the total bundle thickness TT of the banknote bundle has reached a predetermined first bundle thickness threshold value TH1. In this example, the first sensor 81 is configured to detect that the elevating stage 51 has reached a predetermined first threshold position. Note that the first threshold position is below the storage upper limit position, and the distance from the storage upper limit position in the vertical direction corresponds to the first bundle thickness threshold TH1 (specifically, the first bundle thickness threshold TH1). And the distance corresponding to the sum of the thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the lifting / lowering stage 51 reaches the first bundle thickness threshold TH1, the lifting / lowering stage 51 reaches the first threshold position.

<Second sensor>
The second sensor 82 is configured to detect that the total bundle thickness TT of the banknote bundle has reached a predetermined second bundle thickness threshold TH2. In this example, the second sensor 82 is configured to detect that the elevating stage 51 has reached a predetermined second threshold position. The second threshold position is a distance (specifically, the second bundle thickness threshold) that exists below the first threshold position and whose distance from the upper storage position in the vertical direction corresponds to the second bundle thickness threshold TH2. This is a position corresponding to the sum of TH2 and the vertical thickness of the lifting stage 51). With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the elevation stage 51 reaches the second bundle thickness threshold value TH2, the elevation stage 51 reaches the second threshold position.

<Third sensor>
The third sensor 83 is configured to detect that the total bundle thickness TT of the banknote bundle has reached a predetermined third bundle thickness threshold value TH3. In this example, the third sensor 83 is configured to detect that the elevating stage 51 has reached a predetermined third threshold position. The third threshold position is a distance (specifically, the third bundle thickness threshold) that exists below the second threshold position and whose distance from the upper storage position in the vertical direction corresponds to the third bundle thickness threshold TH3. This is a position corresponding to the sum of TH3 and the vertical thickness of the elevating stage 51). With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the elevation stage 51 reaches the third bundle thickness threshold value TH3, the elevation stage 51 reaches the third threshold position.

[Collection processing]
Next, with reference to FIGS. 5-8, operation | movement of the banknote processing apparatus 10 in a collection process is demonstrated. For example, the control unit 80 performs the following operation when the number of banknotes stored in the banknote storage unit 26 exceeds a predetermined collection start number. Or the control part 80 performs the following operation | movement in response to operation (operation for making the banknote processing apparatus 10 perform collection processing) of the operation display part 12 by an operator. 6 to 8, hatched blocks indicate banknote bundles (or aggregates of a predetermined number of banknotes to be banknote bundles). In this example, the first transport bundle number is set to “4”, the second transport bundle number is set to “2”, and the third transport bundle number is set to “1”.

<Step S11>
First, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle (the total bundle thickness BT of the banknote bundles stored in the bundle storage section 50) is less than the first bundle thickness threshold TH1. In this example, when there is no detection by the first sensor 81 (that is, detection that the total bundle thickness TT of the banknote bundle has reached the first bundle thickness threshold value TH1), the control unit 80 calculates the total bundle thickness TT of the banknote bundle. Is determined to be lower than the first bundle thickness threshold TH1, and when there is detection by the first sensor 81, it is determined that the total bundle thickness TT of the banknote bundle is equal to or greater than the first bundle thickness threshold TH1. If the total bundle thickness TT of the banknote bundle is less than the first bundle thickness threshold value TH1, the process proceeds to step S12. Otherwise, the process proceeds to step S13.

<Step S12 (first collection operation)>
When the total bundle thickness TT of the banknote bundle is less than the first bundle thickness threshold TH1, the control unit 80 starts the first collection operation. In the first collection operation, the control unit 80 counts the number of transported bundles (the sum of the number of banknote bundles scheduled to be fed out from the bundle generation unit 30 and the number of banknote bundles transported to the bundle transport unit 60). Controls the operation of the banknote handling apparatus 10 so as to be the first number of transported bundles. In this example, as illustrated in FIG. 6, the control unit 80 controls the operation of the banknote handling apparatus 10 so that the number of transported bundles is “4”. In the example of FIG. 6, the number of banknote bundles scheduled to be fed out from the bundle generation unit 30 is “2”, and the number of banknote bundles conveyed to the bundle conveyance unit 60 is “2”. It is.

  Specifically, in the first collection operation, the control unit 80 continuously transports banknotes from the banknote storage unit 26 (or the insertion unit 22 and the banknote temporary storage unit 25) toward the bundle generation unit 30. The banknote transport unit 27, the bundle generation unit 30, and the bundle transport unit 60 are controlled so that the transport bundle number becomes the first transport bundle number (four bundles in this example). When the banknote bundle (one bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the composite bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, and When the total bundle thickness TT is lower than the first bundle thickness threshold TH1, the first collection operation is continued, and when the total bundle thickness TT of the banknote bundle has reached the first bundle thickness threshold TH1, the first collection operation is performed. Exit.

<Step S13>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or greater than the first bundle thickness threshold TH1, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle is less than the second bundle thickness threshold TH2. In this example, the control unit 80 detects the total bundle thickness TT of the banknote bundle when there is no detection by the second sensor 82 (that is, detection that the total bundle thickness TT of the banknote bundle has reached the second bundle thickness threshold TH2). Is determined to be less than the second bundle thickness threshold TH2, and when there is detection by the second sensor 82, it is determined that the total bundle thickness TT of the banknote bundle is greater than or equal to the second bundle thickness threshold TH2. If the total bundle thickness TT of the banknote bundle is less than the second bundle thickness threshold value TH2, the process proceeds to step S14. Otherwise, the process proceeds to step S15.

<Step S14 (second collection operation)>
When the total bundle thickness TT of the banknote bundle is greater than or equal to the first bundle thickness threshold value TH1 and less than the second bundle thickness threshold value TH2, the control unit 80 performs a second collection operation. In the second collecting operation, the control unit 80 counts the number of transported bundles (the total number of banknote bundles to be fed from the bundle generating unit 30 and the number of banknote bundles transported to the bundle transport unit 60). Controls the operation of the banknote handling apparatus 10 so as to be the second transport bundle number. In this example, as illustrated in FIG. 7, the control unit 80 controls the operation of the banknote handling apparatus 10 so that the number of transported bundles is “2”. In the example of FIG. 7, the number of banknote bundles scheduled to be fed out from the bundle generation unit 30 is “2”, and the number of banknote bundles conveyed to the bundle conveyance unit 60 is “0”. It is.

  Specifically, in the second collection operation, the control unit 80 continuously transports banknotes from the banknote storage unit 26 (or the insertion unit 22 and the banknote temporary storage unit 25) toward the bundle generation unit 30. The banknote transport unit 27, the bundle generation unit 30, and the bundle transport unit 60 are controlled so that the transport bundle number becomes the second transport bundle number (two bundles in this example). When the banknote bundle (one bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the composite bundle thickness TT of the banknote bundle is lower than the second bundle thickness threshold TH2, and the banknote bundle When the total bundle thickness TT is less than the second bundle thickness threshold TH2, the second collection operation is continued, and when the total bundle thickness TT of the banknote bundle has reached the second bundle thickness threshold TH2, the second collection operation is continued. Exit.

  When the first collecting operation is performed before the start of the second collecting operation, the control unit 80 ends the first collecting operation when the total bundle thickness TT of the banknote bundle reaches the first bundle thickness threshold value TH1. The second collecting operation is started. Specifically, the control unit 80 ends the first collection operation when the total bundle thickness TT of the banknote bundle reaches the first bundle thickness threshold value TH1, and the number of bundles corresponding to the first transport bundle number (in this example, 4). The second collecting operation is started after the bundle of banknotes is stored in the bundle storage unit 50.

<Step S15>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or greater than the second bundle thickness threshold value TH2, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle is below the third bundle thickness threshold value TH3. In this example, the control unit 80 detects the total bundle thickness TT of the banknote bundle when there is no detection by the third sensor 83 (that is, detection that the total bundle thickness TT of the banknote bundle has reached the third bundle thickness threshold TH3). Is determined to be less than the third bundle thickness threshold TH3, and when there is detection by the third sensor 83, it is determined that the total bundle thickness TT of the banknote bundle is equal to or greater than the third bundle thickness threshold TH3. If the total bundle thickness TT of the banknote bundle is less than the third bundle thickness threshold TH3, the process proceeds to step S16, and otherwise, the process proceeds to step S17.

<Step S16 (second collection operation)>
When the total bundle thickness TT of the banknote bundle is greater than or equal to the second bundle thickness threshold value TH2 and less than the third bundle thickness threshold value TH3, the control unit 80 performs a third collection operation. In the third collecting operation, the control unit 80 counts the number of transported bundles (the sum of the number of banknote bundles scheduled to be fed out from the bundle generating unit 30 and the number of banknote bundles transported to the bundle transporting unit 60). Controls the operation of the banknote handling apparatus 10 so as to be the third transport bundle number. In this example, as shown in FIG. 8, the control unit 80 controls the operation of the banknote handling apparatus 10 so that the number of transport bundles is “1”. In the example of FIG. 8, the number of banknote bundles scheduled to be fed out from the bundle generation unit 30 is “1”, and the number of banknote bundles conveyed to the bundle conveyance unit 60 is “0”. It is.

  Specifically, in the third collection operation, the control unit 80 continuously transports banknotes from the banknote storage unit 26 (or the insertion unit 22 and the banknote temporary storage unit 25) toward the bundle generation unit 30. The banknote conveyance unit 27, the bundle generation unit 30, and the bundle conveyance unit 60 are controlled so that the number of conveyance bundles becomes the third conveyance bundle number (one bundle in this example). When the banknote bundle (one bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the combined bundle thickness TT of the banknote bundle is lower than the third bundle thickness threshold value TH3. When the total bundle thickness TT is less than the third bundle thickness threshold TH3, the third collection operation is continued, and when the total bundle thickness TT of the banknote bundle has reached the third bundle thickness threshold TH3, the third collection operation is performed. Exit.

  When the second collecting operation is performed before the start of the third collecting operation, the control unit 80 ends the second collecting operation when the total bundle thickness TT of the banknote bundle reaches the second bundle thickness threshold value TH2. The third collection operation is started. Specifically, the control unit 80 ends the second collection operation when the total bundle thickness TT of the banknote bundle reaches the second bundle thickness threshold value TH2, and the number of bundles corresponding to the second transport bundle number (in this example, 2). The third collection operation is started after the bundle of banknotes is stored in the bundle storage unit 50.

<Step S17>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or greater than the third bundle thickness threshold TH3, the control unit 80 controls the operation of the banknote processing apparatus 10 to stop the generation of the banknote bundle. Then, the process ends.

  When the third collection operation is performed before the generation of the banknote bundle is stopped, the banknotes of the number of bundles (one bundle in this example) corresponding to the third transport bundle number after the third collection operation is completed. The bundle is conveyed and stored in the bundle storage unit 50.

[Effects of the embodiment]
As described above, in the banknote processing apparatus 10 according to this embodiment, the operation of the banknote processing apparatus 10 is controlled based on the total bundle thickness TT of banknote bundles (the total bundle thickness of banknote bundles stored in the bundle storage unit 50). By doing so, the operation of the banknote processing apparatus 10 is appropriately controlled without being affected by the change in the number of stored bundles (the number of banknote bundles stored in the bundle storage unit 50) due to the change in the bundle thickness of the banknote bundle. Can do. Further, according to the total bundle thickness TT of the banknote bundle, the total number of transported bundles (the total number of banknote bundles scheduled to be fed out from the bundle generating unit 30 and the number of banknote bundles being transported to the bundle transporting unit 60) ) In stages, one bill bundle generated in the bundle generation unit 30 is transported from the bundle generation unit 30 to the bundle storage unit 50 and stored, and then the next bill bundle in the bundle generation unit 30 is stored. Rather than the case where the operation of the banknote processing apparatus 10 is controlled so that generation is started (in the case of so-called one-bundle conveyance), the processing time for generating a banknote bundle and storing it in the bundle storage unit (collection processing in this example) Can be shortened.

  Further, in the banknote handling apparatus 10 according to this embodiment, three bundle thickness thresholds (first bundle thickness threshold TH1, second bundle thickness threshold TH2, and third bundle thickness threshold TH3) are set, and the total bundle thickness TT of the banknote bundle is set. In response to the increase, the number of transport bundles is gradually reduced from the first transport bundle number to the second transport bundle number and the third transport bundle number. Thus, a plurality of bundles from the bundle generation unit 30 to the bundle storage unit 50 is more than in the case of one bundle conveyance (that is, when banknote bundles are conveyed one bundle at a time from the bundle generation unit 30 to the bundle storage unit 50). The time during which the sheet bundle is continuously conveyed can be lengthened. Therefore, it is possible to shorten the time for processing to generate a banknote bundle and store it in the stack storage unit (collection processing in this example).

  Also, the first bundle thickness threshold TH1 is set to the bundle thickness obtained by multiplying the reference bundle thickness RT by the number of first storage bundles, and the second bundle thickness threshold TH2 is multiplied by the second bundle bundle number by the reference bundle thickness RT. By setting the third bundle thickness threshold TH3 to the bundle thickness obtained by multiplying the reference bundle thickness RT by the number of third storage bundles larger than the second storage bundle number, The bundle thickness threshold values (first bundle thickness threshold value TH1, second bundle thickness threshold value TH2, and third bundle thickness threshold value TH3) are used as the number of stored bundles (first stored bundle number, second stored bundle number, and third stored bundle number). Can be set. Thereby, setting of a bundle thickness threshold value can be facilitated.

  Further, by setting the first transport bundle number so that it is less than or equal to the bundle number obtained by subtracting the first storage bundle number from the second storage bundle number, the total bundle thickness TT of the banknote bundle is set. The banknote bundle and the bundle transport unit scheduled to be fed out from the bundle generation unit 30 when the first bundle thickness threshold TH1 is reached and the number of transport bundles is switched from the first transport bundle number to the second transport bundle number. The banknote bundle being conveyed to 60 (that is, the banknote bundle of the number corresponding to the first conveyance bundle number) is conveyed to the bundle storage unit 50, and the total bundle thickness TT of the banknote bundle reaches the second bundle thickness threshold TH2. This can be prevented. Thereby, the control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

  Further, by setting the second transport bundle number so that it is less than or equal to the bundle number obtained by subtracting the second storage bundle number from the third storage bundle number, the total bundle thickness TT of the banknote bundle is set. A banknote bundle and a bundle transport unit scheduled to be fed out from the bundle generation unit 30 when the transport bundle number is switched from the second transport bundle number to the third transport bundle number when the second bundle thickness threshold TH2 is reached. The banknote bundle conveyed to 60 (that is, the banknote bundle of the number corresponding to the second transport bundle number) is conveyed to the bundle storage unit 50, and the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3. This can be prevented. Thereby, the control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

  In addition, the third transport bundle number is set so as to be less than or equal to the bundle number obtained by subtracting the third storage bundle number from the predetermined upper limit storage bundle number for the bundle storage unit 50. Thus, when the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3 and the generation of the banknote bundle is stopped in the bundle generation section 30, the banknote bundle scheduled to be fed out from the bundle generation section 30. And the banknote bundle (that is, the banknote bundle of the number of bundles equivalent to the number of third transport bundles) being conveyed to the bundle conveyance section 60 is conveyed to the bundle storage section 50 and the total bundle thickness TT of the banknote bundle is It is possible to prevent the storage upper limit bundle thickness (the bundle thickness obtained by multiplying the reference bundle thickness by the upper limit storage bundle number) from being reached. Thereby, the control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

  In addition, when the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3 by setting the third transport bundle number to “1”, the generation of the banknote bundle is stopped in the bundle generation unit 30. The banknote bundle scheduled to be fed out from the bundle generation section 30 and the banknote bundle transported to the bundle transport section 60 (that is, the banknote bundle of the number corresponding to the third transport bundle number) are transported to the bundle storage section 50. Thus, it is possible to reliably prevent the total bundle thickness TT of the banknote bundles from reaching the storage upper limit bundle thickness of the bundle storage unit 50 (the bundle thickness obtained by multiplying the reference bundle thickness by the upper limit storage bundle number). Thereby, the control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

  Further, by providing the first sensor 81, the second sensor 82, and the third sensor 83 corresponding to the first bundle thickness threshold TH1, the second bundle thickness threshold TH2, and the third bundle thickness threshold TH3, respectively, It can be accurately detected that the total bundle thickness TT has reached the bundle thickness threshold (the first bundle thickness threshold TH1, the second bundle thickness threshold TH2, and the third bundle thickness threshold TH3).

(Variation 1 of the banknote handling apparatus)
As shown in FIG. 9, the bundle storage unit 50 may be provided with an upper sensor 86 and a lower sensor 87 instead of the first sensor 81, the second sensor 82, and the third sensor 83.

[Upper sensor]
The upper sensor 86 is configured to detect that the elevating stage 51 has reached the upper threshold position. The upper threshold position is below the storage upper limit position, and the distance from the storage upper limit position in the vertical direction corresponds to the second bundle thickness threshold TH2 (specifically, the second bundle thickness threshold TH2). The distance corresponding to the sum of the thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the elevation stage 51 reaches the second bundle thickness threshold TH2, the elevation stage 51 reaches the upper threshold position.

[Lower sensor]
The lower sensor 87 is configured to detect that the elevating stage 51 has reached the lower threshold position. Note that the lower threshold position is located below the upper threshold position, and the distance from the upper storage position in the vertical direction corresponds to the third bundle thickness threshold TH3 (specifically, the third bundle thickness threshold TH3). And a distance corresponding to the sum of the thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the elevation stage 51 reaches the third bundle thickness threshold TH3, the elevation stage 51 reaches the lower threshold position.

(Control part)
In the example of FIG. 9, the control unit 80 moves up and down by a predetermined forced movement distance DD when the banknote bundle is placed on the lifting stage 51 and no detection is performed by the upper sensor 86 when the lifting stage 51 is lowered. After the stage 51 is lowered, the elevating stage 51 is returned to the original position. The forced movement distance DD is set to a distance corresponding to the bundle thickness obtained by subtracting the first bundle thickness threshold value TH1 from the second bundle thickness threshold value TH2. With such a configuration, when the total bundle thickness TT of the banknote bundle placed on the elevating stage 51 reaches the first bundle thickness threshold TH1, the elevating stage 51 is lowered by the forcible movement distance DD to bring the elevating stage 51 back to the original position. When returning to the position, the elevating stage 51 reaches the upper threshold position. In the example of FIG. 9, the control unit 80 operates as follows.

  When the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 is lowered, the control unit 80 does not detect by the upper sensor 86 (detection that the elevating stage 51 has reached the upper threshold position) and is forced to move. When there is no detection by the upper sensor 86 when the elevating stage 51 is lowered by DD and the elevating stage 51 is returned to the original position, the number of transported bundles (the bundle of banknote bundles scheduled to be fed out from the bundle generating unit 30) The operation of the banknote processing apparatus 10 is controlled such that the number and the total number of banknote bundles being conveyed to the bundle conveyance unit 60 are equal to the first conveyance bundle number.

  In addition, when the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 is lowered, the control unit 80 causes the elevating stage 51 to move down by the forcible movement distance DD without detection by the upper sensor 86. When the upper sensor 86 detects when returning to the original position, the operation of the banknote handling apparatus 10 is controlled so that the number of transported bundles becomes the second number of transported bundles.

  Further, the control unit 80 detects when the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 descends, and detects by the upper sensor 86 and detects by the lower sensor 87 (the elevating stage 51 is at the lower threshold position). When there is no detection of arrival, the operation of the banknote processing apparatus 10 is controlled so that the number of transport bundles becomes the third number of transport bundles.

  And the control part 80 is the banknote processing apparatus 10 so that generation | occurrence | production of a banknote bundle may be stopped, when a banknote bundle is mounted in the raising / lowering stage 51, and there exists detection by the lower side sensor 87, when the raising / lowering stage 51 descend | falls. To control the operation.

[Effects of modification 1 of banknote handling apparatus]
By configuring as described above, the total bundle thickness TT of the bill bundle is controlled by the upper sensor 86 and the lower sensor 87 corresponding to the second bundle thickness threshold value TH2 and the third bundle thickness threshold value TH3 and the control of the elevating stage 52, respectively. It can be detected that the bundle thickness thresholds (first bundle thickness threshold TH1, second bundle thickness threshold TH2, and third bundle thickness threshold TH3) have been reached. Thereby, the sensor corresponding to 1st bundle thickness threshold value TH1 can be reduced.

(Variation 2 of the banknote handling apparatus)
Note that in the banknote handling apparatus 10, two types of collection processing (first collection processing and second collection processing) may be performed. The first collection process and the second collection process generate banknote bundles using banknotes stored in the banknote storage unit 26 (or banknotes inserted into the insertion unit 22 and banknotes stored in the banknote temporary storage unit 25). The process of storing in the bundle storage unit 50. Note that the number of banknote bundles stored in the bundle storage unit 50 in the second collection process is smaller than the number of banknote bundles stored in the bundle storage unit 50 in the first collection process. For example, the first collection process is performed when the bundle storage unit 50 is in a full state (full state), and the second collection process is performed in a state where the bundle storage unit 50 is in a near-full state (a fuller state than in a full state). This is performed when the number of banknote bundles is small and there is room for storing the banknote bundle in the bundle storage unit 50. As an example of the case where the bundle storage unit 50 is in a near-full state, the banknote processing apparatus 10 performs a scrutiny process (the banknote bundle stored in the bundle storage unit 50 is transported to the lifting / lowering passage 61 and then the bundle identification unit 70 When the number of banknote bundles stored in the bundle storage section 50 is limited in order to reliably perform the process of returning the banknote bundle from the lift passage 61 to the bundle storage section 50 while performing identification of Is mentioned. And the control part 80 may be comprised so that the 1st collection control corresponding to a 1st collection process and the 2nd collection control corresponding to a 2nd collection process may be performed. For example, the control unit 80 is configured to switch between the first collection control and the second collection control in accordance with settings (or settings registered in advance) by the operator.

[First collection control]
In the first collection control, the control unit 80 performs an operation similar to the operation illustrated in FIG. That is, when the total bundle thickness TT of the banknote bundle is less than the first bundle thickness threshold TH1, the control unit 80 determines the number of transport bundles (the number of banknote bundles scheduled to be fed from the bundle generation section 30 and the bundle transport). The operation of the banknote handling apparatus 10 is controlled such that the total number of banknote bundles conveyed to the unit 60 is equal to the first conveyance bundle number. Further, the control unit 80 controls the banknotes so that the number of transported bundles becomes the second number of transported bundles when the total bundle thickness TT of the banknote bundles is equal to or greater than the first bundle thickness threshold value TH1 and lower than the second bundle thickness threshold value TH2. The operation of the processing apparatus 10 is controlled. In addition, the control unit 80 controls the banknotes so that the number of transported bundles becomes the third number of transported bundles when the total bundle thickness TT of the banknote bundles is equal to or greater than the second bundle thickness threshold value TH2 and lower than the third bundle thickness threshold value TH3. The operation of the processing apparatus 10 is controlled. And the control part 80 controls operation | movement of the banknote processing apparatus 10 to stop the production | generation of a banknote bundle, when the total bundle thickness TT of banknote bundles is more than 3rd bundle thickness threshold value TH3.

[Second collection control]
In the second collection control, the controller 80 controls the number of transported bundles (the bundle of banknote bundles scheduled to be fed out from the bundle generation unit 30 when the total bundle thickness TT of the banknote bundles is lower than the first bundle thickness threshold TH1. The operation of the bill processing apparatus 10 is controlled so that the number and the total number of bundles of banknote bundles conveyed to the bundle conveyance unit 60 become the predetermined fourth conveyance bundle number. Further, the control unit 80 determines that the number of transport bundles is a predetermined number of fifth transport bundles when the total bundle thickness TT of the banknote bundles is equal to or greater than the first bundle thickness threshold value TH1 and less than the second bundle thickness threshold value TH2. The operation | movement of the banknote processing apparatus 10 is controlled so that it may become. And the control part 80 controls operation | movement of the banknote processing apparatus 10 to stop the production | generation of a banknote bundle, when the total bundle thickness TT of a banknote bundle is more than 2nd bundle thickness threshold value TH2. The fifth transport bundle number is set to a bundle number smaller than the fourth transport bundle number.

  Next, the second collection control of the control unit 80 will be described with reference to FIG. In the second collection control, the control unit 80 performs the following operation.

<Step S21>
First, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle (the total bundle thickness BT of the banknote bundles stored in the bundle storage section 50) is less than the first bundle thickness threshold TH1. If the total bundle thickness TT of the banknote bundle is less than the first bundle thickness threshold TH1, the process proceeds to step S22, and otherwise, the process proceeds to step S23.

<Step S22 (fourth collection operation)>
When the total bundle thickness TT of the banknote bundle is less than the first bundle thickness threshold TH1, the control unit 80 starts the fourth collection operation. In the fourth collecting operation, the control unit 80 controls the operation of the banknote processing apparatus 10 so that the number of transport bundles becomes the fourth number of transport bundles. Note that the number of the fourth transport bundles is less than or equal to the number of bundles obtained by subtracting the first storage bundle number from the second storage bundle number, like the first transport bundle number. In this example, the first storage bundle number is set to “2”, and the second storage bundle number is set to “7”. The fourth transport bundle number is set to “4”.

<Step S23>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or greater than the first bundle thickness threshold TH1, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle is less than the second bundle thickness threshold TH2. If the total bundle thickness TT of the banknote bundle is less than the second bundle thickness threshold value TH2, the process proceeds to step S24. Otherwise, the process proceeds to step S25.

<Step S24 (Fifth Collection Operation)>
When the total bundle thickness TT of the banknote bundle is equal to or greater than the first bundle thickness threshold value TH1 and less than the second bundle thickness threshold value TH2, the control unit 80 performs a fifth collection operation. In the fifth collecting operation, the control unit 80 controls the operation of the banknote handling apparatus 10 so that the number of transport bundles becomes the fifth number of transport bundles. The fifth transport bundle number is obtained by subtracting the second storage bundle number from the intermediate storage bundle number (the bundle number less than the upper limit storage bundle number) predetermined for the bundle storage unit 50. Are less or the same. In this example, the number of intermediate storage bundles is set to “8”, and the second storage bundle number is set to “7”. The fifth transport bundle number is set to “1”.

  When the fourth collecting operation is performed before the start of the fifth collecting operation, the control unit 80 ends the fourth collecting operation when the total bundle thickness TT of the banknote bundle reaches the first bundle thickness threshold value TH1. When the bundle of bills (four in this example) corresponding to the fourth transport bundle is stored in the bundle storage unit 50, the fifth collecting operation is started.

<Step S25>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or greater than the second bundle thickness threshold TH2, the control unit 80 controls the operation of the banknote processing apparatus 10 to stop the generation of the banknote bundle. Then, the process ends.

[Effects of the second modification of the banknote handling apparatus]
As described above, by sharing the bundle thickness threshold (specifically, the first bundle thickness threshold TH1 and the second bundle thickness threshold TH2) between the first collection control and the second collection control, the first collection is controlled. The number of parts such as sensors can be reduced and the control can be simplified compared to the case where the bundle thickness threshold is not set in common between the control and the second collection control but is set individually.

(Other embodiments)
In addition, the control part 80 is before the number of the banknotes accommodated in the banknote storage part 26 falls below the collection completion | finish number of sheets (or before the bundle number of the banknote bundle accommodated in the bundle storage part 50 reaches | attains the collection completion | finish bundle number). When the collection process is terminated, information that prompts execution of a process (collection process) for collecting the banknote bundle (or the banknote stored in the banknote storage part 26) stored in the bundle storage part 50 is output. It may be configured as follows. For example, the control unit 80 may be configured to display a message prompting the execution of the collection process on the operation display unit 12, or the message prompting the execution of the collection process is owned by an external device (for example, a cashier in charge). (Tablet terminal). By comprising in this way, the empty capacity | capacitance of the banknote accommodating part 26 can be ensured, and the next money_receiving | payment process can be performed normally.
