Description

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

Conventionally, a paper leaf processing device for processing paper sheets such as banknotes and valuable media has been known. Further, it is known that in such a paper leaf processing apparatus, a bundle of paper leaves is generated from a predetermined number of sheets of paper and stored in the bundle storage unit. For example, Patent Document 1 discloses a banknote processing apparatus including a bundling unit (bundle generation unit) that generates a banknote bundle from a predetermined number of banknotes drawn out from a denomination cassette. The banknote bundle generated in the banknote binding unit is transported to the bundle storage unit and stored.

Japanese Unexamined Patent Publication No. 2014-081678

By the way, in a paper leaf processing apparatus such as the bill processing apparatus of Patent Document 1, in order to prevent the occurrence of overflow in the bundle storage portion, the upper limit number of storage bundles (can be stored in the bundle storage portion) with respect to the bundle storage portion. The upper limit of the number of bundles of paper leaf bundles) is set, and when the number of bundles of paper leaf bundles stored in the bundle storage section reaches the upper limit number of storage bundles, the generation of the bundles of paper leaves in the bundle generation section ends. It is conceivable to control the operation of the paper leaf processing apparatus as described above. However, the bundle thickness of the paper leaf bundle changes depending on the state of the paper leaves constituting the paper leaf bundle. For example, the thickness of a banknote bundle (an example of a paper leaf bundle) composed of banknotes having a relatively long circulation period (circulation ticket) is a banknote composed of banknotes having a relatively short circulation period (new ticket). It tends to be thicker than the bundle thickness. Therefore, the number of bundles of paper leaf bundles that can be stored in the bundle storage portion changes depending on the state of the paper leaf bundles. Therefore, bundles of paper leaves in various states (particularly thickness) are stored in the bundle storage unit, and it is difficult to appropriately set the upper limit number of bundles to be stored, so that the operation of the paper leaf processing device is operated. It is difficult to control properly.

Further, in a paper leaf processing device such as the banknote processing device of Patent Document 1, a sensor for detecting the full state of the bundle storage unit (a state in which the bundle storage unit is full of paper leaf bundles) is provided. When the sensor detects the full state of the bundle storage unit, it is conceivable to control the operation of the paper leaf processing device so that the generation of the paper leaf bundle in the bundle generation unit is completed. However, if the bundle of paper leaves that is being transported remains on the transport path between the bundle generation section and the bundle storage section when the generation of the bundle of paper leaves is stopped in the bundle generation section, this transport process is in progress. There is a possibility that the bundle of paper leaves will be conveyed to the bundle storage section and an overflow will occur in the bundle storage section. Therefore, after one bundle of paper sheets generated in the bundle generation unit is transported from the bundle generation unit to the bundle storage unit and stored, the bundle generation unit starts the generation of the next paper leaf bundle. , It is conceivable to control the operation of the paper leaf processing device, but with such control, it is difficult to shorten the processing time for generating the paper leaf bundle and storing it in the bundle storage unit. ..

Therefore, the technique disclosed here is not affected by the change in the number of storage bundles (the number of bundles of banknote bundles stored in the bundle storage unit) due to the change in the bundle thickness of the paper leaf bundle, and the paper leaf processing apparatus. It is an object of the present invention to make it possible to appropriately control the operation and to shorten the processing time for generating a bundle of paper notes and storing it in the bundle storage unit.

An elevating stage that descends so that the uppermost surface of the elevating stage is at a predetermined storage upper limit position with respect to the bundle storage portion, and a sensor that detects the position of the elevating stage are provided, and the control unit is the sensor of the sensor. The total bundle thickness is detected based on the detection result, and the number of conveyed bundles is controlled by controlling the repetition cycle of the operation of the bundle generation unit.

The control unit controls the operation of the paper leaf processing apparatus so that the number of conveyed bundles becomes the number of first conveyed bundles when the total bundle thickness is lower than the first bundle thickness threshold value, and the total bundle thickness When is equal to or higher than the first bundle thickness threshold value and is lower than the second bundle thickness threshold value thicker than the first bundle thickness threshold value, the number of the conveyed bundles is smaller than the number of the first transported bundles. When the operation of the paper leaf processing apparatus is controlled so as to be such that the total bundle thickness is equal to or more than the second bundle thickness threshold value and is lower than the third bundle thickness threshold value thicker than the second bundle thickness threshold value, the said. When the operation of the paper leaf processing apparatus is controlled so that the number of conveyed bundles is less than the number of the second conveyed bundles and the total bundle thickness is equal to or greater than the third bundle thickness threshold value. , The operation of the paper leaf processing apparatus may be controlled so as to stop the production of the paper leaf bundle.

The first bundle thickness threshold value may be set to a bundle thickness obtained by multiplying the bundle thickness of the paper leaf bundle by a predetermined reference bundle thickness and a predetermined number of first storage bundles. .. The second bundle thickness threshold value may be set to a bundle thickness obtained by multiplying the reference bundle thickness by the number of second storage bundles larger than the number of first storage bundles. The third bundle thickness threshold value may be set to a bundle thickness obtained by multiplying the reference bundle thickness by the number of third storage bundles larger than the number of second storage bundles.

The number of the first conveyed bundles may be less than or the same as the number of bundles obtained by subtracting the number of the first stored bundles from the number of the second stored bundles.

The number of the second transported bundles may be less than or the same as the number of bundles obtained by subtracting the number of the second stored bundles from the number of the third stored bundles.

Even if the number of the third transport bundles is less than or the same as the number of bundles obtained by subtracting the number of the third storage bundles from the upper limit number of storage bundles predetermined for the bundle storage portion. Good.

The number of the third conveyed bundles may be 1.

The sensor detects that the total bundle thickness has reached the first bundle thickness threshold and the first sensor is configured to detect that the total bundle thickness has reached the second bundle thickness threshold. The second sensor configured as described above and the third sensor configured to detect that the total bundle thickness has reached the third bundle thickness threshold value may be included . Then, the control unit controls the operation of the paper leaf processing device so that the number of conveyed bundles becomes the number of the first conveyed bundles when there is no detection by the first sensor, and the first sensor controls the operation. When there is detection and there is no detection by the second sensor, the operation of the paper leaf processing device is controlled so that the number of conveyed bundles becomes the number of the second conveyed bundles, and there is detection by the second sensor. Moreover, when there is no detection by the third sensor, the operation of the paper leaf processing device is controlled so that the number of conveyed bundles becomes the number of the third conveyed bundles, and when there is detection by the third sensor, It may be configured to control the operation of the paper leaf processing apparatus so as to stop the production of the paper leaf bundle.

Below, the distance between the upper sensor configured to detect and the elevating stage is below the upper threshold position and the distance between the upper storage upper limit position is a distance corresponding to the third bundle thickness threshold. It may include a lower sensor configured to detect that the side threshold position has been reached. The control unit sets the first bundle thickness threshold value from the second bundle thickness threshold value when the paper leaf bundle is placed on the elevating stage and there is no detection by the upper sensor when the elevating stage is lowered. The elevating stage may be configured to return to the original position after the elevating stage is lowered by a forced movement distance corresponding to the bundle thickness obtained by subtraction. Then, when the paper leaf bundle is placed on the elevating stage and the elevating stage is lowered, the control unit lowers the elevating stage by the forced movement distance without detection by the upper sensor and elevates the elevating stage. When the upper sensor does not detect when the stage is returned to the original position, the operation of the paper leaf processing device is controlled so that the number of conveyed bundles becomes the number of the first conveyed bundles, and the elevating stage is moved to the elevating stage. When a bundle of paper sheets is placed and the elevating stage is lowered, there is no detection by the upper sensor, and when the elevating stage is lowered by the forced movement distance and the elevating stage is returned to its original position, the upper side is used. When there is detection by the sensor, the operation of the paper leaf processing device is controlled so that the number of the conveyed bundles becomes the number of the second conveyed bundles, and the paper leaf bundles are placed on the elevating stage to elevate the elevating. When the upper sensor detects the stage and the lower sensor does not detect it when the stage descends, the operation of the paper leaf processing device is controlled so that the number of conveyed bundles becomes the number of the third conveyed bundles. Then, when a bundle of paper sheets is placed on the elevating stage and there is a detection by the lower sensor when the elevating stage descends, the paper sheets are stopped so as to stop the generation of the bundle of paper sheets. It may be configured to control the operation of the processing device.

The control unit may be configured to perform either the first collection control or the second collection control. In the first collection control, the control unit of the paper leaf processing apparatus causes the number of conveyed bundles to be the number of the first conveyed bundles when the total bundle thickness is lower than the first bundle thickness threshold. When the operation is controlled and the total bundle thickness is equal to or higher than the first bundle thickness threshold value and lower than the second bundle thickness threshold value, the paper sheets are arranged so that the number of conveyed bundles becomes the number of the second conveyed bundles. The operation of the processing apparatus is controlled, and when the total bundle thickness is equal to or more than the second bundle thickness threshold value and is lower than the third bundle thickness threshold value, the number of conveyed bundles becomes the number of the third conveyed bundles.

Alternatively, the control unit 80 processes the banknotes so that the banknote processing device 10 starts the collection process in response to the operation of the operation display unit 12 by the operator (an operation for causing the banknote processing device 10 to execute the collection process). It controls each part of the device 10. Then, when the number of banknotes stored in the banknote storage unit 26 is less than the predetermined number of completed collections (or the number of bundles of banknotes stored in the bundle storage unit 50 is predetermined, the control unit 80 collects the banknotes. When the number of finished bundles is reached), each part of the banknote processing device 10 is controlled so that the collection process is completed in the banknote processing device 10.

In this example, the control unit 80 sets the number of banknote bundles stored in the bundle storage unit 50 to the number of collection end bundles before the number of banknotes stored in the banknote storage unit 26 falls below the number of banknotes stored in the banknote storage unit 26. Even before it reaches), when the total bundle thickness of the banknote bundles stored in the bundle storage unit 50 reaches a predetermined bundle thickness threshold value (specifically, the third bundle thickness threshold value TH3 described later), The bundle generation unit 30 controls each unit of the banknote processing device 10 so that the generation of banknote bundles is stopped and the collection process is completed. This control will be described in detail later.

[Control in collection process]
In the collection process, the control unit 80 conveys the banknotes stored in the banknote storage unit 26 (or the banknotes inserted in the insertion unit 22 or the banknotes stored in the temporary banknote holding unit 25) to the bundle generation unit 30. In this way, the bill storage unit 26 (or the bill insertion unit 22, the bill temporary holding unit 25) and the bill transport unit 27 are controlled. Further, in the collection process, the control unit 80 is scheduled to be paid 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 device 10 (particularly, so that the total number of banknote bundles being transported and the total number of banknote bundles transported to the bundle transport unit 60 (hereinafter referred to as “the number of banknotes transported”) changes stepwise. The operation of the bundle generation unit 30 and the bundle transfer unit 60) is controlled. Specifically, the control unit 80 performs the following operations.

The control unit 80 controls the operation of the banknote processing device 10 so that the number of banknotes to be transported becomes a predetermined number of first banknotes when the total thickness of the banknote bundles is less than the first bundle thickness threshold TH1.

Further, in the control unit 80, when the total bundle thickness of the banknote bundle is equal to or higher than the first bundle thickness threshold value TH1 and is lower than the predetermined second bundle thickness threshold value TH2, the number of conveyed bundles is the predetermined second transport bundle. The operation of the banknote processing device 10 is controlled so as to have the number of bundles. The second bundle thickness threshold TH2 is set to a thicker bundle thickness than the first bundle thickness threshold TH1. The number of second transport bundles is set to be smaller than the number of first transport bundles.

Further, when the total bundle thickness of the banknote bundle is equal to or higher than the second bundle thickness threshold value TH2 and is lower than the predetermined third bundle thickness threshold value TH3, the control unit 80 transfers the number of the bundled banknotes to the predetermined third transport. The operation of the banknote processing device 10 is controlled so as to have the number of bundles. The third bundle thickness threshold TH3 is set to a thicker bundle thickness than the second bundle thickness threshold TH2. The number of third transport bundles is set to be smaller than the number of second transport bundles.

Then, the control unit 80 controls the operation of the bill processing device 10 so as to stop the generation of the bill bundle when the total bundle thickness of the bill bundle is equal to or higher than the third bundle thickness threshold TH3.

[Control of bundle generator]
Further, in this example, the control unit 80 is configured to control the operation of the bundle generation unit 30 by controlling the transfer of banknotes to the bundle generation unit 30 by the banknote transfer unit 27. Specifically, the control unit 80 starts the generation of banknote bundles by the bundle generation unit 30 by controlling the banknote transport unit 27 so that the banknotes are conveyed to the bundle generation unit 30. Further, the control unit 80 conveys banknotes so that the timing at which a predetermined number (for example, 100) of banknotes are accumulated in the banknote collecting unit 31 becomes a desired cycle (a cycle in which the number of conveyed bundles becomes the desired number of conveyed bundles). By controlling the unit 27, the number of transported bundles (the total number of banknote bundles scheduled to be delivered from the bundle generating unit 30 and the total number of banknote bundles transported to the bundle transport unit 60) is controlled. Then, the control unit 80 stops the generation of the banknote bundle by the bundle generation unit 30 by controlling the banknote transport unit 27 so that the banknotes are not conveyed to the bundle generation unit 30.

The control unit 80 controls the banding unit 32 so that the timing at which the banknote bundles are generated in the banding unit 32 becomes a desired cycle (the cycle in which the number of transported bundles becomes the desired number of transported bundles). You may control the number.

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

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

Further, 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 thinner than the reference bundle thickness RT.

<First bundle thickness threshold>
The first bundle thickness threshold TH1 is set to a bundle thickness obtained by multiplying the reference bundle thickness RT by a predetermined number of first storage bundles. In this example, the number of first storage bundles 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 number of second storage bundles. The number of second storage bundles is set to be larger than the number of first storage bundles. In this example, the number of second storage bundles 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 number of third storage bundles. The third storage bundle number is set to a larger number than the second storage bundle number. In this example, the number of third storage bundles is set to "9".

<Number of first transport bundles>
The number of first conveyed bundles is smaller than or the same as the number of bundles obtained by subtracting the number of first stored bundles from the number of second stored bundles. In this example, the number of first storage bundles is set to "2" and the number of second storage bundles is set to "7". The number of first transport bundles is set to "4".

<Number of second transport bundles>
The number of second transported bundles is smaller than or the same as the number of bundles obtained by subtracting the number of second stored bundles from the number of third stored bundles. In this example, the number of second storage bundles is set to "7" and the number of third storage bundles is set to "9". The number of second transport bundles is set to "2".

<Number of third transport bundles>
The number of the third conveyed bundles is smaller than or the same as the number of bundles obtained by subtracting the number of the third stored bundles from the upper limit number of stored bundles predetermined for the bundle storage unit 50. In this example, the upper limit number of storage bundles in the bundle storage unit 50 is set to "10", and the number of third storage bundles is set to "9". The number of third transport bundles is set to "1".

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

<Elevating stage and passage sensor>
The elevating stage 51 is configured so that a bundle of banknotes is placed and elevated. The passage sensor 52 is the uppermost surface of the banknote bundle placed on the elevating stage 51 (the upper surface of the banknote bundle when one banknote bundle is placed, or the upper surface of the banknote bundle when a plurality of banknote bundles are placed). It is configured to detect that the uppermost banknote bundle (upper surface) has passed a predetermined storage upper limit position (position of "0" in FIG. 4) with respect to the bundle storage unit 50.

Then, when the banknote bundle is placed, the elevating stage 51 descends so that the uppermost surface of the placed banknote bundle becomes the storage upper limit position. Specifically, the elevating stage 51 starts descending when the banknote bundle is placed, and is detected by the passing sensor 52 (the uppermost surface of the banknote bundle placed on the elevating stage 51 has reached the storage upper limit position). Detects) and stops descending.

<First sensor>
The first sensor 81 is configured to detect that the total bundle thickness TT of the bundle of banknotes has reached a predetermined first bundle thickness threshold TH1. In this example, the first sensor 81 is configured to detect that the elevating stage 51 has reached a predetermined first threshold position. The first threshold position exists 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). It is a position corresponding to the sum of the thickness of the elevating stage 51 and the thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the first bundle thickness threshold TH1, the elevating 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 bundle of banknotes 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 exists below the first threshold position, and the distance between the second threshold position and the storage upper limit position in the vertical direction corresponds to the second bundle thickness threshold TH2 (specifically, the second bundle thickness threshold). It is a position (distance corresponding to the total of the thickness of TH2 and the vertical thickness of the elevating stage 51). With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the second bundle thickness threshold TH2, the elevating 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 bundle of banknotes has reached a predetermined third bundle thickness threshold 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 exists below the second threshold position, and the distance from the storage upper limit position in the vertical direction corresponds to the third bundle thickness threshold TH3 (specifically, the third bundle thickness threshold). It is a position (distance corresponding to the total of the thickness of TH3 and the vertical thickness of the elevating stage 51). With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the third bundle thickness threshold TH3, the elevating stage 51 reaches the third threshold position.

[Collection process]
Next, the operation of the banknote processing apparatus 10 in the collection process will be described with reference to FIGS. 5 to 8. For example, the control unit 80 performs the following operations when the number of banknotes stored in the banknote storage unit 26 exceeds a predetermined collection start number. Alternatively, the control unit 80 performs the following operations in response to an operation of the operation display unit 12 by the operator (an operation for causing the bill processing device 10 to execute the collection process). In addition, in FIGS. 6 to 8, the hatched block indicates a banknote bundle (or a collection of a predetermined number of banknotes to be a banknote bundle). Further, in this example, the number of first conveyed bundles is set to "4", the number of second conveyed bundles is set to "2", and the number of third conveyed bundles 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 unit 50) is less than the first bundle thickness threshold TH1. In this example, the control unit 80 does not detect by the first sensor 81 (that is, the detection that the total bundle thickness TT of the banknote bundle reaches the first bundle thickness threshold TH1), the total bundle thickness TT of the banknote bundle. Is 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 higher than the first bundle thickness threshold TH1. If the total bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, the process proceeds to step S12, and if not, the process proceeds to step S13.

<Step S12 (first collection operation)>
When the total bundle thickness TT of the banknote bundle is lower 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 receives the number of bundles to be conveyed (the total number of bundles of banknotes to be unwound from the bundle generation unit 30 and the number of bundles of banknotes to be conveyed to the bundle transfer unit 60). The operation of the banknote processing device 10 is controlled so that is the number of first transport bundles. In this example, as shown in FIG. 6, the control unit 80 controls the operation of the banknote processing device 10 so that the number of conveyed bundles is “4”. In the example of FIG. 6, the number of banknote bundles scheduled to be delivered from the bundle generation unit 30 is "2", and the number of banknote bundles transported to the bundle transfer unit 60 is "2". Is.

Specifically, in the first collection operation, the control unit 80 continuously conveys banknotes from the banknote storage unit 26 (or the insertion unit 22, the bill temporary holding unit 25) to 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 number of transport bundles is the first transport bundle number (4 bundles in this example). Then, when the banknote bundle (1 bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the synthetic bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1 of the banknote bundle. 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 reaches the first bundle thickness threshold TH1, the first collection operation is continued. To finish.

<Step S13>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or higher 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 lower than the second bundle thickness threshold TH2. In this example, the control unit 80 does not detect by the second sensor 82 (that is, the detection that the total bundle thickness TT of the banknote bundle reaches the second bundle thickness threshold TH2), the total bundle thickness TT of the banknote bundle. Is lower 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 equal to or higher than the second bundle thickness threshold TH2. If the total bundle thickness TT of the banknote bundle is lower than the second bundle thickness threshold TH2, the process proceeds to step S14, and if not, the process proceeds to step S15.

<Step S14 (second collection operation)>
When the total bundle thickness TT of the banknote bundle is equal to or higher than the first bundle thickness threshold TH1 and lower than the second bundle thickness threshold TH2, the control unit 80 performs the second collection operation. In the second collection operation, the control unit 80 receives the number of bundles to be conveyed (the total number of bundles of banknotes to be delivered from the bundle generation unit 30 and the number of bundles of banknotes to be conveyed to the bundle transfer unit 60). The operation of the banknote processing device 10 is controlled so that is the number of second transport bundles. In this example, as shown in FIG. 7, the control unit 80 controls the operation of the banknote processing device 10 so that the number of conveyed bundles is “2”. In the example of FIG. 7, the number of banknote bundles scheduled to be delivered from the bundle generation unit 30 is "2", and the number of banknote bundles transported to the bundle transport unit 60 is "0". Is.

Specifically, in the second collection operation, the control unit 80 continuously conveys banknotes from the banknote storage unit 26 (or the insertion unit 22, the bill temporary holding unit 25) to 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 number of transport bundles is the second number of transport bundles (two bundles in this example). Then, when the banknote bundle (1 bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the synthetic 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 lower than the second bundle thickness threshold TH2, the second collection operation is continued, and when the total bundle thickness TT of the banknote bundle reaches the second bundle thickness threshold TH2, the second collection operation is continued. To finish.

If the first collection operation is performed before the start of the second collection operation, 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 TH1. The second collection 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 TH1, and the number of bundles corresponding to the number of first conveyed bundles (4 in this example). The second collection operation is started after the bundle of banknotes (bundle) 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 higher than the second bundle thickness threshold TH2, the control unit 80 determines whether or not the total bundle thickness TT of the banknote bundle is lower than the third bundle thickness threshold TH3. In this example, the control unit 80 does not detect by the third sensor 83 (that is, the detection that the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3), the total bundle thickness TT of the banknote bundle. Is lower 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 higher than the third bundle thickness threshold TH3. If the total bundle thickness TT of the banknote bundle is lower than the third bundle thickness threshold TH3, the process proceeds to step S16, and if not, the process proceeds to step S17.

<Step S16 (second collection operation)>
When the total bundle thickness TT of the banknote bundle is equal to or higher than the second bundle thickness threshold TH2 and lower than the third bundle thickness threshold TH3, the control unit 80 performs the third collection operation. In the third collection operation, the control unit 80 receives the number of bundles to be conveyed (the total number of bundles of banknotes to be unwound from the bundle generation unit 30 and the number of bundles of banknotes to be conveyed to the bundle transfer unit 60). The operation of the banknote processing device 10 is controlled so that is the third number of bundles to be conveyed. In this example, as shown in FIG. 8, the control unit 80 controls the operation of the banknote processing device 10 so that the number of conveyed bundles is “1”. In the example of FIG. 8, the number of banknote bundles scheduled to be delivered from the bundle generation unit 30 is "1", and the number of banknote bundles transported to the bundle transport unit 60 is "0". Is.

Specifically, in the third collection operation, the control unit 80 continuously conveys banknotes from the banknote storage unit 26 (or the insertion unit 22, the bill temporary holding unit 25) to 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 number of transport bundles is the third transport bundle number (1 bundle in this example). Then, when the banknote bundle (1 bundle) is stored in the bundle storage unit 50, the control unit 80 determines whether or not the synthetic bundle thickness TT of the banknote bundle is lower than the third bundle thickness threshold TH3, and the banknote bundle When the total bundle thickness TT is lower than the third bundle thickness threshold TH3, the third collection operation is continued, and when the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3, the third collection operation is continued. To finish.

If the second collection operation is performed before the start of the third collection operation, 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 TH2. Then, 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 TH2, and the number of bundles corresponding to the number of second conveyed bundles (2 in this example). The third collection operation is started after the banknote bundle (bundle) 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 higher than the third bundle thickness threshold TH3, the control unit 80 controls the operation of the banknote processing device 10 so as to stop the generation of the banknote bundle. Then, the process ends.

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

[Effect of the embodiment]
As described above, in the bill processing device 10 according to this embodiment, the operation of the bill processing device 10 is controlled based on the total bundle thickness TT of the bill bundle (the total bundle thickness of the bill bundle stored in the bundle storage unit 50). By doing so, the operation of the banknote processing device 10 can be appropriately controlled without being affected by the change in the number of stored banknotes (the number of banknote bundles stored in the banknote storage unit 50) due to the change in the banknote bundle thickness. Can be done. Further, the total number of banknote bundles transported according to the total banknote bundle thickness TT (the total number of banknote bundles scheduled to be delivered from the bundle generation unit 30 and the total number of banknote bundles transported to the bundle transport unit 60). ) Is changed stepwise, so that one banknote bundle generated in the bundle generation unit 30 is conveyed from the bundle generation unit 30 to the bundle storage unit 50 and stored, and then the next banknote bundle is stored in the bundle generation unit 30. The time required for the process of generating a banknote bundle and storing it in the bundle storage unit (collection process in this example) rather than controlling the operation of the banknote processing device 10 so that the generation is started (in the case of so-called one-bundle transport). Can be shortened.

Further, in the bill processing apparatus 10 according to this embodiment, three bundle thickness threshold values (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 bill bundle is set. The number of transport bundles is gradually reduced from the number of first transport bundles to the number of second transport bundles and the number of third transport bundles in accordance with the increase in the number of bundles. As a result, a plurality of banknote bundles are transported from the bundle generation unit 30 to the bundle storage unit 50 as compared with the case of one bundle transportation (that is, when the banknote bundles are transported one bundle at a time from the bundle generation unit 30 to the bundle storage unit 50). It is possible to lengthen the time for which the bundle of paper notes is continuously transported. Therefore, it is possible to shorten the time for the process of generating a banknote bundle and storing it in the bundle storage unit (collection process in this example).

Further, 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 stored bundles, and the second bundle thickness threshold TH2 is multiplied by the reference bundle thickness RT by the number of second stored bundles. By setting the bundle thickness obtained by multiplying the reference bundle thickness RT by the number of third stored bundles larger than the number of the second stored bundles, the third bundle thickness threshold TH3 is set to the bundle thickness obtained. The bundle thickness threshold (first bundle thickness threshold TH1, second bundle thickness threshold TH2, and third bundle thickness threshold TH3) is used as the number of stored bundles (the number of the first stored bundle, the number of the second stored bundle, and the number of the third stored bundle). Can be set. This makes it easy to set the bundle thickness threshold.

Further, by setting the number of first transport bundles so that the number of bundles is less than or equal to the number obtained by subtracting the number of first storage bundles from the number of second storage bundles, the total bundle thickness TT of the banknote bundles can be increased. When the first bundle thickness threshold TH1 is reached and the number of transported bundles is switched from the number of first transported bundles to the number of second transported bundles, the banknote bundle and the bundle transport unit scheduled to be unwound from the bundle generation unit 30. The banknote bundles conveyed to 60 (that is, the number of banknote bundles corresponding to the number of first conveyed bundles) are conveyed to the bundle storage unit 50, and the total bundle thickness TT of the banknote bundles reaches the second bundle thickness threshold TH2. Can be prevented. As a result, control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

Further, by setting the number of the second transport bundles so as to be smaller than or the same as the number of bundles obtained by subtracting the number of the second storage bundles from the number of the third storage bundles, the total bundle thickness TT of the banknote bundles can be increased. When the second bundle thickness threshold TH2 is reached and the number of transported bundles is switched from the number of second transported bundles to the number of third transported bundles, the banknote bundle and the bundle transport unit scheduled to be unwound from the bundle generation unit 30. The banknote bundle transported to 60 (that is, the banknote bundle having the number of bundles corresponding to the number of second transported bundles) is transported to the bundle storage unit 50, and the total bundle thickness TT of the banknote bundle reaches the third bundle thickness threshold TH3. Can be prevented. As a result, control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

Further, the number of third conveyed bundles is set so as to be less than or equal to the number of bundles obtained by subtracting the number of third stored bundles from the predetermined upper limit number of stored bundles for the bundle storage unit 50. As a result, 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 unit 30, the banknote bundle is scheduled to be delivered from the bundle generation unit 30. And the banknote bundles transported to the bundle transport unit 60 (that is, the banknote bundles having the number of bundles corresponding to the third transport bundle number) are transported to the bundle storage unit 50, and the total bundle thickness TT of the banknote bundles is the bundle storage unit 50. 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 number of storage bundles). As a result, control for preventing the occurrence of overflow in the bundle storage unit 50 can be accurately performed.

Further, by setting the number of third conveyed bundles to "1", 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 unit 30. , The banknote bundle scheduled to be unwound from the bundle generation unit 30 and the banknote bundle conveyed to the bundle transfer unit 60 (that is, the banknote bundle of the number of bundles corresponding to the number of third transport bundles) is conveyed to the bundle storage unit 50. Therefore, it is possible to reliably prevent the total bundle thickness TT of the banknote bundle 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). As a result, 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, the paper leaf bundle can be formed. It can be accurately detected that the total bundle thickness TT has reached the bundle thickness threshold values (first bundle thickness threshold value TH1, second bundle thickness threshold value TH2, and third bundle thickness threshold value TH3).

(Modification 1 of the bill processing device)
As shown in FIG. 9, the bundle storage unit 50 may be provided with an upper sensor 86 and a lower sensor 87 in place 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 exists below the storage upper limit position, and the distance between the storage upper limit position and 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 corresponds to the total thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the second bundle thickness threshold TH2, the elevating 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. The lower threshold position exists below the upper threshold position, and the distance between the lower threshold position and the storage upper limit position in the vertical direction corresponds to the third bundle thickness threshold TH3 (specifically, the third bundle thickness threshold TH3). And the total thickness of the elevating stage 51 in the vertical direction). With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the third bundle thickness threshold TH3, the elevating stage 51 reaches the lower threshold position.

[Control unit]
In the example of FIG. 9, when the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 is not detected by the upper sensor 86 when the elevating stage 51 is lowered, the control unit 80 moves up and down by a predetermined forced movement distance DD. The elevating stage 51 is configured to return to its original position after the stage 51 is lowered. The forced movement distance DD is set to a distance corresponding to the bundle thickness obtained by subtracting the first bundle thickness threshold TH1 from the second bundle thickness threshold TH2. With such a configuration, when the total bundle thickness TT of the banknote bundles placed on the elevating stage 51 reaches the first bundle thickness threshold TH1, the elevating stage 51 is lowered by the forced movement distance DD to return the elevating stage 51 to the original. When returning to the position, the elevating stage 51 reaches the upper threshold position. Then, in the example of FIG. 9, the control unit 80 operates as follows.

The control unit 80 does not detect by the upper sensor 86 (detection that the elevating stage 51 has reached the upper threshold position) when the elevating stage 51 is placed on the elevating stage 51 and the elevating stage 51 descends, and the forced movement distance. When the elevating stage 51 is lowered by DD and the elevating stage 51 is returned to the original position, if there is no detection by the upper sensor 86, the number of conveyed bundles (bundle of banknote bundles scheduled to be unwound from the bundle generation unit 30). The operation of the banknote processing device 10 is controlled so that the number and the total number of banknote bundles transported to the bundle transport unit 60 are the first number of banknotes to be transported.

Further, the control unit 80 lowers the elevating stage 51 by the forced movement distance DD without detection by the upper sensor 86 when the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 descends. When there is detection by the upper sensor 86 when returning to the original position, the operation of the banknote processing device 10 is controlled so that the number of conveyed bundles becomes the number of second conveyed bundles.

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

Then, the control unit 80 stops the generation of the banknote processing device 10 when the lower sensor 87 detects when the banknote bundle is placed on the elevating stage 51 and the elevating stage 51 descends. Control the operation of.

[Effect of Modification 1 of Banknote Processing Device]
With the above configuration, the total bundle thickness TT of the bundle of bills can be increased by controlling the upper sensor 86 and the lower sensor 87 corresponding to the second bundle thickness threshold TH2 and the third bundle thickness threshold TH3, and the elevating stage 52, respectively. It is possible to detect that the bundle thickness threshold (first bundle thickness threshold TH1, second bundle thickness threshold TH2, and third bundle thickness threshold TH3) has been reached. As a result, the number of sensors corresponding to the first bundle thickness threshold TH1 can be reduced.

(Modification 2 of the bill processing device)
The banknote processing apparatus 10 may perform two types of collection processing (first collection processing and second collection processing). In the first collection process and the second collection process, a banknote bundle is generated using the banknotes stored in the banknote storage unit 26 (or the banknotes inserted in the insertion unit 22 and the banknotes stored in the temporary banknote holding unit 25). This is a process of storing the product in the bundle storage unit 50. 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 stores the bundle storage unit 50 in a near full state (a bundle storage unit 50 rather than a full state). This is performed when the number of bundles of banknote bundles is small and the bundle storage unit 50 has a margin for storing banknote bundles). As an example of setting the bundle storage unit 50 to the near full state, the banknote processing device 10 performs a close examination process (the banknote bundle stored in the bundle storage unit 50 is conveyed to the elevating passage 61, and then the banknote bundle is stored in the bundle identification unit 70. The number of banknote bundles stored in the bundle storage unit 50 is limited in order to ensure that the banknote bundle is returned from the elevating passage 61 to the bundle storage unit 50 while identifying the above. Can be mentioned. Then, the control unit 80 may be configured to perform the first collection control corresponding to the first collection process and the second collection control corresponding to the second collection process. For example, the control unit 80 is configured to switch between the first collection control and the second collection control according to the setting (or the setting registered in advance) by the operator.

[1st collection control]
In the first collection control, the control unit 80 performs the same operation as that shown in FIG. That is, when the total bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, the control unit 80 has the number of bundles to be transported (the number of bundles of banknote bundles scheduled to be delivered from the bundle generation unit 30 and the bundle transport). The operation of the banknote processing device 10 is controlled so that the total number of banknote bundles transported to the unit 60 is the first number of banknotes transported. Further, the control unit 80 sets the number of banknotes to be transported so that the number of banknotes to be transported becomes the number of second banknotes when the total bundle thickness TT of the banknote bundles is equal to or higher than the first bundle thickness threshold TH1 and lower than the second bundle thickness threshold TH2. Controls the operation of the processing device 10. Further, the control unit 80 sets the number of banknotes to be transported so that the number of banknotes to be transported becomes the number of third banknotes when the total bundle thickness TT of the banknote bundles is equal to or higher than the second bundle thickness threshold TH2 and is lower than the third bundle thickness threshold TH3. Controls the operation of the processing device 10. Then, the control unit 80 controls the operation of the bill processing device 10 so as to stop the generation of the bill bundle when the total bundle thickness TT of the bill bundle is equal to or higher than the third bundle thickness threshold TH3.

[Second collection control]
In the second collection control, when the total bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, the control unit 80 receives the number of transported bundles (bundle of banknote bundles scheduled to be delivered from the bundle generation unit 30). The operation of the banknote processing device 10 is controlled so that the number and the total number of banknote bundles transported to the bundle transport unit 60) becomes a predetermined fourth transport bundle number. Further, when the total bundle thickness TT of the banknote bundle is equal to or higher than the first bundle thickness threshold TH1 and lower than the second bundle thickness threshold TH2, the control unit 80 sets the number of conveyed bundles to a predetermined number of fifth conveyed bundles. The operation of the banknote processing device 10 is controlled so as to be. Then, the control unit 80 controls the operation of the banknote processing device 10 so as to stop the generation of the banknote bundle when the total banknote thickness TT of the banknote bundle is equal to or higher than the second bundle thickness threshold TH2. The number of fifth conveyed bundles is set to be smaller than the number of fourth conveyed bundles.

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 operations.

<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 unit 50) is less than the first bundle thickness threshold TH1. If the total bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, the process proceeds to step S22, and if not, the process proceeds to step S23.

<Step S22 (fourth collection operation)>
When the total bundle thickness TT of the banknote bundle is lower than the first bundle thickness threshold TH1, the control unit 80 starts the fourth collection operation. In the fourth collection operation, the control unit 80 controls the operation of the banknote processing device 10 so that the number of conveyed bundles becomes the number of the fourth conveyed bundles. It should be noted that the number of the fourth transported bundles is smaller than or the same as the number of bundles obtained by subtracting the number of the first stored bundles from the number of the second stored bundles, similarly to the number of the first transported bundles. In this example, the number of first storage bundles is set to "2" and the number of second storage bundles is set to "7". The number of fourth transport bundles is set to "4".

<Step S23>
On the other hand, when the total bundle thickness TT of the banknote bundle is equal to or higher 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 lower than the second bundle thickness threshold TH2. If the total bundle thickness TT of the banknote bundle is lower than the second bundle thickness threshold TH2, the process proceeds to step S24, and if not, 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 higher than the first bundle thickness threshold TH1 and lower than the second bundle thickness threshold TH2, the control unit 80 performs the fifth collection operation. In the fifth collection operation, the control unit 80 controls the operation of the banknote processing device 10 so that the number of transported bundles becomes the fifth number of transported bundles. The number of fifth conveyed bundles is the number of bundles obtained by subtracting the number of second stored bundles from the number of intermediate stored bundles (the number of bundles smaller than the upper limit number of stored bundles) predetermined for the bundle storage unit 50. Is less or the same. In this example, the number of intermediate storage bundles is set to "8" and the number of second storage bundles is set to "7". The number of fifth transport bundles is set to "1".

If the fourth collection operation is performed before the start of the fifth collection operation, the control unit 80 ends the fourth collection operation when the total bundle thickness TT of the banknote bundle reaches the first bundle thickness threshold TH1. When the number of banknote bundles (4 in this example) corresponding to the number of 4th transport bundles is stored in the bundle storage unit 50, the fifth collection operation is started.

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

[Effect of Modification 2 of Banknote Processing Device]
As described above, the first collection is performed by sharing the bundle thickness threshold value (specifically, the first bundle thickness threshold value TH1 and the second bundle thickness threshold value TH2) between the first collection control and the second collection control. Compared with the case where the bundle thickness threshold value is not standardized and is set individually between the control and the second collection control, the number of parts such as a sensor can be reduced and the control can be simplified.

(Other embodiments)
In the control unit 80, before the number of banknotes stored in the banknote storage unit 26 falls below the number of banknotes stored in the banknote storage unit 26 (or before the number of banknote bundles stored in the bundle storage unit 50 reaches the number of banknotes collected). When the collection process is completed, the information prompting the execution of the process (collection process) for collecting the banknote bundle (or the banknotes stored in the banknote storage unit 26) stored in the bundle storage unit 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 person in charge of accounting). It may be configured to send to a tablet terminal). With this configuration, the free space of the bill storage unit 26 can be secured, and the next deposit processing can be performed normally.

Further, in the above description, the banknote processing device 10 for processing banknotes and banknote bundles has been given as an example of the paper sheet processing device, but the paper sheet processing device is a valuable medium and a bundle of valuable media (paper sheets). It may be composed of a valuable medium processing device (an example of a paper leaf processing device) for processing a bundle of paper notes). The valuable medium is a check, a gift certificate, or the like.

Further, in the above description, the bundle storage unit 50 is configured to store the plurality of banknote bundles so that the bundle thickness direction of the plurality of banknote bundles faces the vertical direction and the plurality of banknote bundles are arranged in a row in the vertical direction. As an example, in the bundle storage unit 50, the bundle thickness direction of a plurality of banknote bundles is oriented in the horizontal direction (horizontal direction), and the plurality of banknote bundles are arranged in a row in the horizontal direction (horizontal direction). It may be configured to store a plurality of banknote bundles.

Further, the predetermined number of paper leaves constituting the paper leaf bundle may be of the same type (for example, the same denomination) or may be of different types (for example, different denominations).

Further, the above embodiments may be combined as appropriate. The above embodiments are essentially preferred examples and are not intended to limit the scope of the techniques disclosed herein, their applications, or their uses.

As described above, the technique disclosed herein is useful for a paper leaf processing apparatus.
