Description

The present invention relates to a paper sheet processing apparatus.

Conventionally, paper sheets such as banknotes are taken in from the deposit unit, identified by the identification unit, temporarily stored in a temporary storage unit, then sorted by predetermined denomination and stored in storage units by denomination. There is known a paper sheet handling apparatus for storage. In such a paper sheet processing apparatus, a temporary storage unit and a storage unit for each denomination store paper sheets by wrapping them around a drum, which is a rotating body, one by one while sandwiching them between tapes. There is a drum-type (or tape-type) storing and feeding device that feeds paper sheets by rotating the drum in the reverse direction (see, for example, Patent Document 1).
Compared to a stacker that stores paper sheets in an accumulated state, the drum-type storing and feeding device changes the posture of the paper sheets one by one (the thickness of the paper sheets when viewed from the thickness direction). Since it can be paid out without changing the direction), it has the feature that it is difficult for delivery failure to occur.

By the way, with the miniaturization of the paper sheet processing apparatus as a whole, each of the plurality of drum type storing and feeding devices arranged in the paper sheet processing apparatus is made up of a compact unit. Therefore, in order to maximize the storage of paper sheets in the drum-type storing and feeding device provided in a limited space, the pitch of the paper sheets wound on the drum (the leading edge of the preceding paper sheet to the following paper sheet It is required that the pitch of the paper sheets is reduced and the paper sheets are wound on the drum so that the distance to the leading edge of the paper sheet) is as small as possible.

However, in order to wind the paper sheets on the drum in a state where the pitches of the paper sheets are narrowed, the length of the paper sheets in the direction in which the paper sheets are conveyed toward the drum type storing and feeding device (conveyance direction) is required. If it is not possible to correctly grasp the width, an abnormality in which a succeeding paper sheet collides with a preceding paper sheet (paper sheet rear-end jam error) may occur, which may lead to poor storage of the paper sheets in the drum. For example, when some paper sheets are conveyed toward the drum-type storing and feeding device in an oblique posture (an attitude in which one side of the paper sheets is inclined with respect to the conveying direction of the paper sheets) in the conveying path, If the length of the paper sheet in the skewed posture cannot be correctly grasped, the preceding paper sheet may collide with the succeeding paper sheet.

Accordingly, it is an object of the present invention to provide a paper sheet processing apparatus capable of suppressing poor storage of paper sheets in the drum even when the paper sheets are wound on the drum with the pitch of the paper sheets reduced. aim.

According to one aspect of the present invention, there is provided a paper sheet processing apparatus comprising: a conveying passage through which paper sheets are conveyed; an identification unit that identifies the paper sheets being conveyed in the conveying passage; A drum-type storing and feeding device for storing sheets by wrapping them around a drum, which is a rotating body, while sandwiching the sheets one by one with a tape, and delivering the sheets one by one to the conveying path; and paper for the drum-type storing and feeding device. a paper sheet length detection means for detecting the length of the paper sheet along the sheet storage and delivery direction, wherein the identification unit acquires information on the entire surface of the paper sheet conveyed on the conveying path. It has a full surface information acquisition sensor and outputs the angular coordinate position of the paper sheet based on the acquired information of the entire surface of the paper sheet, and the paper sheet length detection means is the drum storage and delivery device. In the storage operation of the paper sheets, the length of the paper sheets along the storing and feeding direction is calculated based on the angular coordinate position.

The identification unit 17 has a full surface information acquisition sensor 301 that acquires information on the entire surface of the bill S being conveyed in the conveying path 20, as shown in FIGS. Arrows in FIG. 2 indicate the transport direction of the bills S in the transport passage 20 . The full-surface information acquisition sensor 301 acquires information on the shape and size of the entire banknote S viewed from the thickness direction of the banknote S. The full-surface information acquisition sensor 301 is specifically a line sensor (CIS sensor: also referred to as a contact image sensor) extending in the passage width direction. The entire surface information acquisition sensor 301 acquires the image of the bill S being conveyed in the conveying path 20 line by line at predetermined time intervals, arranges them in time series and synthesizes them, thereby obtaining image information of the entire bill S. is acquired as "information on the entire surface of the banknote S". For the full-surface information acquisition sensor 301, for example, an optical camera such as a CCD camera capable of acquiring image information of the entire bill S at one time may be used.

Based on the "information on the entire surface of the banknote S" acquired by the full-surface information acquisition sensor 301, the identification unit 17 discriminates whether the banknote S is genuine or counterfeit, and determines whether the banknote S is highly soiled. A control unit 15 discriminates whether or not it is a defaced note, discriminates whether or not it is a damaged note with a high degree of damage such as a stub or a torn note, and identifies the denomination of the note. output to In response to this, the control unit 15 counts the bills S that can be accepted by denomination, determines the transport destination of each bill S, and controls the transport path 20 .

The recognition unit 17 has angular coordinate position calculating means 302 for calculating the angular coordinate position of the bill S based on the information of the bill S obtained by the full surface information obtaining sensor 301 (information of the entire surface of the bill S). As shown in FIG. 3, the angular coordinate position indexing means 302 calculates the position of the bill S on the xy coordinate plane viewed from the thickness direction of the bill S based on the "information on the entire surface of the bill S" acquired by the full surface information acquisition sensor 301. Calculate the angular coordinate positions indicating the positions of the four corners (x1, y1), (x2, y2), (x3, y3), (x4, y4). In FIG. 3 , the x-coordinate is the coordinate in the passage width direction (horizontal direction of the device), and the y-coordinate is the coordinate in the conveying direction of the paper money S in the conveying passage 20 . The full surface information acquisition sensor 301 for acquiring “information on the entire surface of the banknote S” used for calculating the angular coordinate position is not limited to a sensor for acquiring image information. A thickness detection sensor that acquires thickness distribution information as "information on the entire surface of the banknote S" may be used. The angular coordinate position calculating means 302 outputs data of the calculated angular coordinate positions to the banknote length detecting means 201 (sheet length detecting means) of the control section 15 shown in FIG.

In the banknote processing apparatus 10, banknotes S set in the depositing unit 11 are transported from the depositing unit 11 toward the identification unit 17 by the front side feeding path portion 21a and the intermediate feeding path portion 21b of the depositing transportation path 21, for example, and are identified. After being identified by the unit 17, the sheets are conveyed to the drum type storing and feeding device 18(A) by the intermediate feeding path portions 21b and 21c and the rear side feeding path portion 21d.

Determination of damage as to whether or not it is a ticket and discrimination of denomination are performed. In addition to these identifications, the identifying unit 17 identifies the presence or absence of transport abnormalities including double feeding and skewed feeding (skewed feeding with an angle of inclination exceeding a specified value (for example, 10 degrees)) of the banknote S.

As a result of identification by the identifying unit 17, normal banknotes S that are genuine, not damaged, not damaged, and have no transport abnormality, and are identified as acceptable, are sent to the intermediate transport paths 21b, 21c of the deposit transport path 21 and The rear-side feeding path portion 21d conveys to the drum type storage and feeding device 18(A), and the drum type storage and feeding device 18(A) stores (see the thick solid line in FIG. 4). Rejected banknotes S that are other banknotes S that are identified as unacceptable by the identification unit 17 are conveyed to the connection conveyance path 36 by the intermediate conveyance path sections 21b and 21c of the deposit conveyance path 21, and then transferred to the connection conveyance path 36 and the output. The gold transport path 35 transports the money to the dispensing unit 12 (see the thick solid line to the thick broken line in FIG. 4). The control unit 15 stores the storage order and the denomination of each of the banknotes S temporarily stored in the drum type storing and feeding device 18(A).

Reject banknotes S that are rejected by the dispensing unit 12 under the control of the control unit 15 in the deposit process include counterfeit notes, damaged notes with a defacement rate (degree of defacement) higher than a specified value, and a defacement rate (degree of damage). is higher than the specified value, and transported abnormal notes such as double-fed banknotes in which a plurality of banknotes S are conveyed in a state where at least a part of them are overlapped, or skewed banknotes in which the inclination angle of the banknotes S exceeds the specified value. .

When all banknotes S set in the deposit unit 11 have been conveyed to either the drum storage and delivery device 18 (A) or the payment unit 12, the identification result of the identification unit 17 is used to identify the drum storage and delivery device 18 (A). ) displays the deposit result including amount information such as the number of stored banknotes S by denomination and the total amount. The banknotes S conveyed to the dispensing unit 12 can be taken out of the device. It should be noted that, apart from the dispensing section 12, a reject section may be provided so that the banknotes S can be taken out of the apparatus, and the banknotes S that cannot be accepted may be conveyed to this reject section. Then, the control unit 15 causes the operation display unit 14 to display a display prompting determination of whether to confirm the deposit processing, to cancel the deposit processing, or to additionally insert banknotes S into the deposit unit 11 .

[Distribution processing]
The distribution process is a process of sorting and storing the banknotes S temporarily stored in the drum storage and delivery device 18 (A) in the above-described deposit processing in the drum storage and delivery device 18 (B) inside the device.

After the amount information after the payment processing is displayed on the operation display unit 14, when the operator inputs an operation to confirm the payment processing on the operation display unit 14, the control unit 15 controls the drum storage and delivery device 18 (A). Then, the transport path 20 and an appropriate one of the eight drum-type storing and feeding devices 18 (B) transport and store the banknotes S, for example, along the distribution processing route indicated by the thick line in FIG.

That is, the drum-type storing and feeding device 18 (A) feeds out the banknotes S that have been temporarily stored one by one with an interval between them, and The upper transport path portion 55a of the vertical transport path 55 and the storage transport path 57 transport. During the transportation in the intermediate feeding path section 21b, the identification section 17 again identifies the order of identification of the banknotes S and the presence/absence of conveyance abnormalities including double feeding and skew feeding. At this time, the identifying unit 17 does not perform authenticity determination, defacement determination, damage determination, and denomination identification.

Then, if there is no transport abnormality, the control unit 15 determines the denomination of the banknote S based on the identification order of the banknotes S identified by the identification unit 17 and the already stored denomination information at the time of deposit processing. Get and count. The banknotes S obtained and counted in this way are controlled by the control unit 15 in appropriate ones of the storage transport path 57 and the branch transport paths 61 to 63, and eight drum type storing and feeding devices 18 (B). Among them, the banknote S of the determined denomination is stored in the storage destination.

[Withdrawal process]
The withdrawal process is a process of withdrawing banknotes S stored in the drum type storing and feeding device 18 (B) inside the device to the dispensing unit 12 so that they can be taken out of the device.

When an operation for selecting a withdrawal process is input to the operation display unit 14 along with amount information of the banknotes S to be dispensed, the control unit 15 determines the number of withdrawals by denomination according to the amount information, The banknotes S are transported from the drum-type storing and feeding device 18 (B) in which the banknotes S of the denomination are stored to the dispensing unit 12 through the transport path 20, for example, along the dispensing processing route indicated by the thick line in FIG.

For example, a single denomination is specified, and bills S are delivered from one first drum storage and delivery device 18 (B) and transported to the dispensing unit 12. The dispensing process will be described below. become that way. In addition, when a combination of a plurality of denominations is processed for withdrawal, the same processing as for a single denomination is repeated while appropriately switching among the plurality of drum storage and delivery devices 18(B).

That is, the first drum-type storing and feeding device 18 (B) separates and counts the stored banknotes S one by one, and delivers them at intervals. , the storage transport path 57, the upper transport path part 55a of the upper and lower transport paths 55, the intermediate transport path parts 21b and 21c of the deposit transport path 21, the connection transport path 36 and the withdrawal transport path 35, transport to. During the transportation in the intermediate feeding path section 21b, the identification section 17 again identifies the identification order of the bills S and the presence/absence of conveyance abnormality. At this time, the identifying unit 17 does not perform the authenticity determination, the defacement determination, and the denomination determination, but performs the damage determination.

Then, if the banknotes S recognized by the recognition unit 17 are not damaged banknotes such as stubs or double-fed banknotes, the control unit 15 dispenses them to the dispensing unit 12 as they are, including transported abnormal banknotes such as skewed banknotes. Let

On the other hand, if the banknote S identified by the identification unit 17 is a damaged banknote such as a stub or a double-fed banknote, the control unit 15 determines that the banknote S cannot be processed, and the first drum type storing and feeding device determines that the banknote S cannot be processed. 18(B), the driving of the conveying path 20 and the dispensing section 12 is stopped, and the operation display section 14 is caused to display a display prompting error recovery processing. As a result, the operator takes out the banknotes S remaining in the transport path 20, including the banknotes S that have been damaged or the banknotes that have been double fed.

The drum type storing and feeding device 18 has a reel rotating motor 125 which is a stepping motor for rotating the reel rotating shaft 121 . The reel rotating motor 125 rotates the reel rotating shaft 121 and the reel 101 with a driving force, and applies brakes to the reel rotating shaft 121 and the reel 101 to stop them. The reel rotating motor 125 keeps the reel rotating shaft 121 and the reel 101 in a stopped state by magnetic force even when the device power is off. When the tape 30 wound around the reel 101 is pulled out from the reel 101 by driving force, the reel rotation motor 125 rotates along with the tape 30 while applying resistance to generate tension when the device power is on. do. The drum-type storing and feeding device 18 is not provided with an encoder for detecting the amount of rotation of the reel 101 .

The drum type storing and feeding device 18 has a roller shaft 131 which is arranged between the drum 31 and the reel 101 and supported by the housing 110 in a fixed position. The roller shaft 131 is arranged parallel to the drum rotation shaft 111 and the reel rotation shaft 121 . A guide roller 132 is provided on the roller shaft 131 . The guide roller 132 is a free roller and is rotatable around the roller shaft 131 with respect to the housing 110 . A portion of the tape 30 between the drum 31 and the reel 101 is hung on the guide roller 132 . Guide roller 132 forms straight portion 135 of tape 30 with drum 31 . As shown in FIG. 8 , the linear portion 135 and the wound portion 136 of the tape 30 wound around the drum 31 constitute a banknote inlet/outlet port 138 in the drum 31 through which banknotes S are inserted and withdrawn. The drum-type storing and feeding device 18 is not provided with an encoder for detecting the amount of rotation of the guide roller 132 . That is, the drum-type storing and feeding device 18 is not provided with an encoder in the drive system of the tape 30 .

The drum type storing and feeding device 18 has a guide arm 141 which is supported by a roller shaft 131 and rotates about the roller shaft 131 with respect to the housing 110 . A support shaft 142 parallel to the roller shaft 131 is provided at the tip of the guide arm 141 on the side opposite to the roller shaft 131 . A tip roller 143, which is a roller, is provided.

The guide arm 141 extends along the linear portion 135 between the guide roller 132 of the tape 30 and the drum 31 , and the tip roller 143 extends along the winding portion 136 of the tape 30 wound around the drum 31 . It abuts on the radially outer end of the drum 31 . As a result, the guide arm 141 rotates substantially along the linear portion 135 of the tape 30 whose posture changes according to the amount of winding of the tape 30 around the drum 31 .

The drum type storing and feeding device 18 forms a storing and feeding opening 151 through which banknotes S go in and out of the drum type storing and feeding device 18 , and the banknotes extending so as to connect the storing and feeding port 151 and the banknote inlet/outlet 138 of the drum 31 . A guide 152 and a banknote guide 153 are arranged in the vicinity of these banknote guides 152 and 153, and the banknotes S guided between these banknote guides 152 and 153 are moved between the storage/delivery port 151 and the banknote inlet/outlet 138. It has a plurality of transport rollers 155 that allow These bill guides 152 and 153 and a plurality of conveying rollers 155 constitute a connecting conveying path 157 that connects the storage/feeding port 151 and the bill inlet/outlet 138 . The connecting transport path 157 receives the banknotes S from the transport path 20 and transports them toward the drum 31 , and also receives the banknotes S fed out from the drum 31 and transports them toward the transport path 20 .

The drum type storing and feeding device 18 guides the banknotes S transported by the transporting path 20 and delivered to the storing and feeding opening 151 through the connected transporting path 157 by the banknote guides 152 and 153 , and moves the banknotes S to the drum 31 by the plurality of transporting rollers 155 . is conveyed toward the banknote inlet/outlet 138 of . Further, the drum rotation motor 115 rotates the drum rotating shaft 111 and the drum 31 so as to receive and store the banknotes S transported through the connecting transport path 157 in the banknote storage direction (clockwise in FIGS. 7 to 9). direction). At that time, the control unit 15 controls the rotational speed of the drum 31 so as to synchronize with the conveying speed of the connecting conveying path 157 .

Then, the banknotes S transported to the banknote inlet/outlet 138 by the connecting transport path 157 are wrapped around the winding portion 136 of the tape 30 which together constitute the banknote inlet/outlet 138, and immediately before being wound together with the banknotes S around the winding portion 136. It is pushed between the linear portion 135 and wound around the winding portion 136 together with the portion forming the linear portion 135 of the tape 30 . As a result, the banknote S is sandwiched in the radial direction of the drum 31 by the winding portion 136 of the tape 30 and the portion of the tape 30 that is wound around the winding portion 136 together with the banknote S. The drum storage and delivery device 18 thus separates the banknotes S transported through the transport path 20 and delivered to the storage and delivery port 151 at predetermined intervals in the direction in which the banknotes S are transported, that is, in the direction in which the banknotes S are stored and delivered. The tape 30 is wrapped around the drum 31 one by one while being sandwiched by the tape 30, and stored in the winding portion 136 of the tape 30. - 特許庁

Here, the drum 31 and the winding portion 136 of the tape 30 wound around the drum 31 constitute a drum storage portion 161 for storing bills S therein. Therefore, in other words, the banknotes S transported to the banknote inlet/outlet 138 by the connecting transport path 157 are transported to the drum storage unit 161 constituting the banknote inlet/outlet 138 and immediately before being wound around the drum storage unit 161 together with the banknotes S. , and is wound around the drum housing portion 161 together with the portion forming the linear portion 135 of the tape 30 . At this time, the portion of the tape 30 wound around the drum housing portion 161 becomes the drum housing portion 161, and the bills S are stored in this drum housing portion 161. FIG.

In addition, the drum type storing and feeding device 18 rotates the reel rotating shaft 121 and the reel 101 with the reel rotating motor 125 in the tape winding direction (counterclockwise direction in FIGS. 7 to 9), which is the direction in which the tape 30 is wound around the reel 101. ), the portion of the tape 30 on the reel 101 side is wound around the reel 101 , and the tape 30 is pulled out from the drum storage portion 161 . Then, the tape 30 is pulled out from the winding portion 136 wound around the drum 31 to constitute the drum storage portion 161, and the banknotes S, which had been sandwiched by the tape 30 in the drum storage portion 161 until then, are pulled out together with the tape 30. It is drawn out from the drum housing portion 161 toward the housing and feeding opening 151 side. Then, the bill S is conveyed by a plurality of conveying rollers 155 while being guided by the bill guides 152 and 153 of the connecting conveying passage 157 , delivered to the conveying passage 20 from the storage and feeding opening 151 , and conveyed through the conveying passage 20 . Also at this time, the controller 15 controls the rotation speed of the reel 101 so as to synchronize the delivery speed of the drum 31 with the transport speed of the connecting transport path 157 .

Here, in the banknote processing apparatus 10, the banknotes S move in such a posture that the long sides are along the passage width direction and the short sides are along the banknote conveying direction, as described above. Therefore, in the connecting and conveying passage 157 in the drum type storing and feeding device 18, the banknotes S are similarly guided by the bill guides 152 and 153 with their long sides along the width direction of the passage and their short sides along the banknote conveying direction. It will move in a posture that follows the The banknotes S are stored in the drum storage section 161 and delivered from the drum storage section 161 with the short sides along the storage and delivery direction. In the drum type storing and feeding device 18, since the banknotes S are arranged along the width direction of the passage, the drum 31 has a long cylindrical shape in the axial direction along the width of the passage (not shown). and reels 101 are provided separately in the axial direction of the drum 31, which is the width direction of the passage.

A bill detection sensor 171 is provided between the two tapes 30 in the housing 110 . The banknote detection sensor 171 is provided at a position equivalent to the banknote entrance/exit 138 in the transport direction of the banknote S, and detects the presence or absence of the banknote S at this position. The banknote detection sensor 171 is a light-shielding optical sensor composed of a light-emitting sensor 172 and a light-receiving sensor 173 provided so as to sandwich the banknote S at the banknote inlet/outlet 138 in the thickness direction.

If there is a bill S between the light emitting sensor 172 and the light receiving sensor 173, the light emitted from the light emitting sensor 172 is blocked by the bill S, and the light receiving sensor 173 does not receive the light. If there is, it is detected that there is a bill S at the position of the bill detection sensor 171 . If there is no bill S between the light emitting sensor 172 and the light receiving sensor 173, the bill detection sensor 171 is in a translucent state in which the light emitted from the light emitting sensor 172 is not blocked and is received by the light receiving sensor 173. If it is in the light state, it is detected that there is no bill S at the position of the bill detection sensor 171 . The banknote detection sensor 171 is provided on the side of the banknote inlet/outlet 138 of the drum 31, and is stored inside the drum type storage/feeding device 18 and stored in the drum storage section 161, or fed out from the drum storage section 161 and stored in the drum type storage/feeding device 18. The paper money S delivered to the outside of the storing and delivering device 18 is detected.

In the transport path 20, a count sensor ( passage sensor) 181 is provided. The count sensor 181 is a light-shielding optical sensor composed of a light-emitting sensor 182 and a light-receiving sensor 183 which are provided so as to sandwich the banknotes S in the transport path 20 in the thickness direction. If there is a bill S between the light emitting sensor 182 and the light receiving sensor 183, the light emitted from the light emitting sensor 182 is blocked by the bill S and the count sensor 181 enters a light blocking state in which light is not received by the light receiving sensor 183. For example, it detects that there is a bill S at the position of the count sensor 181 . If there is no banknote S between the light emitting sensor 182 and the light receiving sensor 183, the count sensor 181 enters a light transmitting state in which the light emitted from the light emitting sensor 182 is not blocked and is received by the light receiving sensor 183. If it is in the state, it is detected that there is no bill S at the position of the count sensor 181 . The count sensor 181 changes from the light-transmitting state to the light-blocking state, and then when it becomes the light-transmitting state, detects that one bill S has passed the position of the count sensor 181 .

As shown in FIG. 10, two count sensors 181 are arranged with an interval in the passage width direction (horizontal direction of the device). The interval between the two count sensors 181 along the passage width direction is shorter than the long side of the banknote S. As a result, even if the bill S is conveyed in the conveying path 20 in an oblique posture as illustrated in FIG. 10 , the bill S can pass through the two count sensors 181 .

<Bill Storage Operation of Drum Type Storage and Feeding Device 18>
7 to 9, the controller 15 drives the drum rotation motor 115 to move the drum 31 in the banknote storage direction (clockwise direction in FIGS. 7 to 9). ). Then, as the drum 31 rotates in the banknote storage direction, the reel 101 rotates the tape 30 in the tape feeding direction opposite to the tape winding direction (clockwise direction in FIGS. 7 to 9). The tape 30 is pulled out from the reel 101 by rotating due to tension. Then, the control unit 15 winds the banknote S entering the storage and delivery port 151 of the drum type storage and delivery device 18 from the transport path 20 side to the drum 31 while sandwiching the banknote S with the tape 30 at the position of the banknote inlet/outlet port 138 . . As a result, the bills S are stored in the drum storing portion 161 of the drum type storing and feeding device 18 .

Along with the storing operation, the control unit 15 counts the number of banknotes S to be stored by detection by the count sensor 181 provided in the conveying path 20 near the storing/feeding port 151 . Further, the banknote interval detection means 202 (paper sheet interval detection means) (see FIG. 1) of the control unit 15 continuously conveys the bills toward the storage/delivery opening 151 based on the detection information output from the count sensor 181 . Detect the interval of the banknotes S to be stacked. As shown in FIG. 11 and the like, the interval between the banknotes S is the interval between the trailing end of the banknote S (preceding banknote S) leading toward the storage and delivery port 151 and the front end of the following banknote S (subsequent banknote S). is D. Specific detection of the interval D between the banknotes S will be described below.

First, the count sensor 181 detects the time ( banknote non-detection time) is output to the banknote interval detection means 202 of the control unit 15 as data representing the interval D between the banknotes S. FIG. After that, the banknote interval detection means 202 calculates the interval D between the banknotes S based on the banknote non-detection time data output from the count sensor 181 and the transport speed of the banknotes S in the transport path 20 . The interval D between the banknotes S in the transport path 20 is detected each time the banknote S passes the count sensor 181 .

Along with the storage operation, the banknote length detection means 201 of the control unit 15 detects the angular coordinate position of the banknote S output from the angular coordinate position indexing means 302 of the identification unit 17, and the drum type storage and feeding operation is performed. The length of the banknote S along the banknote storage direction (storage and delivery direction) with respect to the device 18 is calculated. Specifically, the banknote length detection means 201, as shown in FIG. The difference between the minimum value and the maximum value of the y-coordinates in the y-axis direction (conveyance direction, storage and delivery direction) is calculated as the length L2 of the banknote S along the y-axis direction. Therefore, the angular coordinate position calculating means 302 of the identification unit 17 may calculate only the y-coordinates of the four corners of the banknote S, for example.

The banknote S illustrated in FIG. 3 is conveyed in the y-axis negative direction (upward in FIG. 3) in an oblique posture so that the left end thereof leads. Therefore, among the y-coordinates of the four corners of the banknote S, the second y-coordinate "y1" from the left is the minimum value, and the second y-coordinate "y4" from the right is the maximum value. Therefore, the banknote length detection means 201 calculates the length L2 of the banknote S using the following formula.
L2 = y4 - y1
Although not illustrated, for example, when the banknote S is conveyed in the negative direction of the y-axis in an oblique posture so that the right end of the banknote S leads, the banknote length detection means 201 determines the length L2 of the banknote S by the following equation. calculate.
L2 = y3 - y2
When one point on the y-coordinate corresponds to the actual length (for example, 0.5 mm), the banknote length detection means 201 multiplies the difference by the actual length to obtain the banknote in the conveying direction. The actual length L2 of S can be calculated.
The length L2 of the banknote S is detected each time the banknote S passes through the full-surface information acquisition sensor 301 of the recognition unit 17 .

Further, the controller 15 controls the length L2 of the leading banknote S detected by the banknote length detection means 201 and the leading banknote S detected by the banknote interval detection means 202 as shown in FIG. The rotation speed of the drum 31 is controlled based on the interval D between the banknote S and the following banknote S. The rotation control of the drum 31 in the storage operation of the banknotes S will be described below.

The rotation control of the drum 31 in the storage operation of the banknotes S is performed by the controller 15 controlling the rotational speed of the drum 31 ( This is done by calculating the drum winding speed).
(Drum winding speed) = (reference speed) x (length conversion) x (bill spacing correction) (1)

Here, the "reference speed" is the rotation speed of the drum 31 corresponding to the cumulative winding length (the length of the tape 30 wound on the drum 31), which will be described later.

"Length conversion" is a value calculated by the following formula (2).
(Length conversion) = (winding banknote length)/(reference banknote length) (2)
Here, the “rolled banknote length” is the length L2 of the preceding banknote S detected by the banknote length detection means 201 (banknote length L2). In addition, the “reference banknote length” is the length of the short side of the standard banknote S (reference banknote S) (for example, 82 mm), and is the length of the banknote storage when the standard banknote S is conveyed without being skewed. It is the length of the banknote S along the direction (storage and delivery direction).

"Bill space correction" is a value calculated by the following formula (3).
(Correction between banknotes)=(reference banknote pitch)/(winding banknote pitch) (3)
Here, the "winding banknote pitch" means the length L2 (banknote length L2) of the leading banknote S detected by the banknote length detection means 201, and the leading banknote S and the trailing banknote S detected by the banknote interval detection means 202 It is the sum of the distance D from the banknote S, that is, the pitch P for one banknote S from the front end of the preceding banknote S to the front end of the following banknote S (banknote pitch P). In addition, the “reference banknote pitch” is the pitch of one banknote S serving as a reference (reference banknote pitch; for example, 143 mm).

A process of continuously storing the preceding banknotes S in the drum type storage and feeding device 18 (after the preceding banknotes S are stored in the drum type storage and feeding device 18, the subsequent banknotes S are stored in the drum type storage and feeding device 18). processing), the control unit 15 controls the rotation speed (winding speed) of the drum 31 for each banknote S by using the above-described calculation formulas (1) to (3).

For example, when the pitch P for one banknote S (banknote pitch P) exceeds the reference banknote pitch, in other words, the pitch for one banknote S derived from the banknote pitch P and the transport speed of the banknote S in the transport path 20 exceeds a predetermined reference value (for example, 143 msec), the control unit 15 switches the rotation speed of the drum 31 when the preceding banknote S is stored to a second rotation speed slower than the first rotation speed. , the drum 31 is driven so as to reduce the interval between the banknotes S stored in the drum 31 (the interval between the preceding banknote S and the following banknote S). The value (143 msec) exemplified as the predetermined reference value of the passage time is a value when seven banknotes S are conveyed in the conveying path 20 per second, but the value is not limited to this.

When the control unit 15 controls the rotation speed of the drum 31 as described above, the interval between the banknotes S when wound around the drum 31 is made smaller than the interval between the banknotes S while being conveyed in the conveying path 20. It can be stored (close the space). This point will be described below.

When the passage time for one banknote S exceeds the predetermined reference value, the banknote S is conveyed at intervals larger than the interval between the banknotes S determined by the specifications of the device. It is being transported. If the bills S conveyed in the conveying passage 20 at such intervals are stored in the drum type storing and feeding device 18 at the same intervals, they cannot be efficiently stored in the drum type storing and feeding device 18, and the drum type It becomes difficult to satisfy the specification value (for example, 600 sheets at maximum) of the storage capacity of the storing and feeding device 18 . Therefore, the control unit 15 sets the rotational speed of the drum 31 when storing the subsequent banknotes S to a slower rotational speed (second rotational speed) than the rotational speed (first rotational speed) of the drum 31 when storing the preceding banknotes S. ), the banknotes S transported at a constant speed in the transport path 20 and headed for the drum type storing and feeding device 18 are closer to the drum 31 than the banknotes S being transported in the transport path 20. It is possible to store the banknotes S by reducing the interval between the banknotes S wound around (close the interval). As a result, more banknotes S can be stored in the drum type storing and feeding device 18 .

A plurality of examples of the rotation speed (winding speed) of the drum 31 controlled by the calculation formulas (1) to (3) will be described below with reference to FIGS. 11 to 19. FIG.
In the example shown in FIG. 11, the banknote length L2 is the reference value (that is, the length of the reference banknote S), and the banknote pitch P is the reference banknote pitch. In this case, the "length conversion" and the "spacing correction" in the formula (1) are both 1.00, so the rotation speed of the drum 31 becomes the reference speed (100% of the reference speed). Therefore, the banknotes S are stored in the drum-type storing and feeding device 18 while maintaining the interval D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 .

In the example shown in FIG. 12, the banknote pitch P is the standard banknote pitch shown in FIG. 11, but the banknote length L2 is shorter than the length of the standard banknote S shown in FIG. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is longer than the example (reference example) shown in FIG. 11 . In this case, the "spacing correction" in formula (1) is 1.00, but the "length conversion" is less than 1.00 (0.76). For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is slower than the reference speed (76% of the reference speed). Therefore, the interval between the preceding banknote S and the following banknote S is set shorter than the interval D between the preceding banknote S and the following banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 13, the banknote pitch P is the reference banknote pitch, but the banknote length L2 is longer than the length of the standard banknote S because the preceding banknote S is in the oblique posture. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is shorter than the example (reference example) shown in FIG. 11 . In this case, the "spacing correction" in formula (1) is 1.00, but the "length conversion" exceeds 1.00 (1.04). For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is faster than the reference speed (104% of the reference speed). Therefore, the interval between the preceding banknote S and the subsequent banknote S is set longer than the interval D between the preceding banknote S and the subsequent banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 14, the banknote length L2 is the length of the standard banknote S, but the banknote pitch P is shorter than the standard banknote pitch. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is shorter than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) is 1.00, but the "spacing correction" exceeds 1.00 (1.08). For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is faster than the reference speed (108% of the reference speed). Therefore, the interval between the preceding banknote S and the subsequent banknote S is set longer than the interval D between the preceding banknote S and the subsequent banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 15, the banknote length L2 is shorter than the length of the standard banknote S, and the banknote pitch P is shorter than the standard banknote pitch. Further, the interval D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is longer than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) is less than 1.00 (0.76), and the "spacing correction" is greater than 1.00 (1.08). Also, the degree of "length conversion" falling below 1.00 is greater than the degree of "spacing correction" exceeding 1.00. For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is slower than the reference speed (81% of the reference speed). Therefore, the interval between the preceding banknote S and the following banknote S is set shorter than the interval D between the preceding banknote S and the following banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 16, since the leading banknote S is in a skewed posture, the banknote length L2 is longer than the length of the standard banknote S, and the banknote pitch P is shorter than the standard banknote pitch. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is shorter than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) exceeds 1.00 (1.04), and the "spacing correction" also exceeds 1.00 (1.08). For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is faster than the reference speed (111% of the reference speed). Therefore, the interval between the preceding banknote S and the subsequent banknote S is set longer than the interval D between the preceding banknote S and the subsequent banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 17, the banknote length L2 is the length of the standard banknote S, but the banknote pitch P is longer than the standard banknote pitch. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is longer than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) is 1.00, but the "spacing correction" is less than 1.00 (0.93). For this reason, the rotational speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is slower than the reference speed (93% of the reference speed). Therefore, the interval between the preceding banknote S and the following banknote S is set shorter than the interval D between the preceding banknote S and the following banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 18, the banknote length L2 is shorter than the length of the standard banknote S, and the banknote pitch P is longer than the standard banknote pitch. Therefore, the distance D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is longer than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) is less than 1.00 (0.76), and the "spacing correction" is also less than 1.00 (0.93). For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is slower than the reference speed (71% of the reference speed). Therefore, the interval between the preceding banknote S and the following banknote S is set shorter than the interval D between the preceding banknote S and the following banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

In the example shown in FIG. 19, since the leading banknote S is in a skewed posture, the banknote length L2 is longer than the length of the standard banknote S, and the banknote pitch P is longer than the standard banknote pitch. Further, the interval D between the preceding banknote S and the subsequent banknote S transported in the transport path 20 is longer than the example (reference example) shown in FIG. 11 . In this case, the "length conversion" in formula (1) exceeds 1.00 (1.04), and the "spacing correction" falls below 1.00 (0.93). Also, the degree to which the "spacing correction" falls below 1.00 is greater than the degree to which the "length conversion" exceeds 1.00. For this reason, the rotation speed of the drum 31 after storing the preceding banknotes S in the drum type storing and feeding device 18 is slower than the reference speed (97% of the reference speed). Therefore, the interval between the preceding banknote S and the following banknote S is set shorter than the interval D between the preceding banknote S and the following banknote S transported in the transport passage 20 (in other words, the example shown in FIG. 11 (reference The banknotes S are stored in the drum-type storing and feeding device 18 so that the interval between the preceding banknote S and the following banknote S in Example) is satisfied.

Furthermore, when storing bills S in the drum storage and feeding device 18, the controller 15 controls the length L2 of the bills S calculated by the bill length detection means 201 and the length L2 of the bills S detected by the bill interval detection means 202. A cumulative winding length, which will be described later, is calculated based on the interval D of the bills S and stored in the storage unit 16 . Further, the control unit 15 causes the storage unit 16 to store the number of bills S detected by the count sensor 181 . That is, the storage unit 16 stores the stored number of banknotes S stored in the drum-type storing and feeding device 18 and the accumulated winding length.

Then, when the final banknote S transported to the drum storage and feeding device 18 passes through the count sensor 181, the detection state of the count sensor 181 changes from the banknote detection state (light-shielding state) to the banknote non-detection state (light-transmitting state). Change. After that, when the final banknote S passes through the banknote detection sensor 171, the detection state of the banknote detection sensor 171 changes from the banknote detection state (light shielding state) to the banknote non-detection state (light transmission state).

The drum type storing and feeding device 18 includes drum position detection means 191 for detecting the position of the drum 31 based on the position of the bill S detected by the bill detection sensor 171 . The drum position detection means 191 includes a bill detection sensor 171 . The drum position detection means 191 changes the banknote detection sensor 171 from the banknote detection state (light shielding state) to the banknote non-detection state (light transmission state) by the final banknote S conveyed to the drum storage and feeding device 18 as described above. When it changes, it is detected that the drum 31 is positioned at a predetermined drum standby position. In other words, the drum-type storing and feeding device 18 changes the banknote detection sensor 171 from the banknote detection state (light-shielding state) to the banknote non-detection state (light-transmitting state) as the banknote S to be finally stored in the drum 31 passes. The position of the drum 31 immediately after the change is detected as the drum standby position.

The controller 15 stops driving the drum rotation motor 115 when the drum position detection means 191 detects that the drum 31 is positioned at a predetermined drum standby position. Then, the drum 31 stops at a predetermined drum standby position where the next bill S is to be received. In other words, the drum position detection means 191 changes the banknote detection sensor 171 from the banknote detection state (light shielding state) to the banknote detection state (light shielding state) by the passage of the banknotes S stored in the drum 31 during the storage operation of the banknotes S in the drum storage and feeding device 18 . When the banknote non-detecting state (light-transmitting state) is reached, it is detected that the drum 31 is positioned at the drum standby position. In a non-operating state in which no banknotes S are stored or delivered, the drum type storage and delivery device 18 stops the drum 31 at this drum waiting position in order to prepare for the next banknote S storage and delivery operations. and wait.

<Banknote feeding operation of drum storage and feeding device 18>
When the banknotes S are delivered from the drum storage and delivery device 18, the control unit 15 drives the reel rotation motor 125 to rotate the reel 101 in the tape winding direction (counterclockwise direction in FIGS. 7 to 9). Then, as the reel 101 rotates in the tape winding direction, the drum 31 rotates in the banknote delivery direction (counterclockwise direction in FIGS. 7 to 9) in which banknotes S are delivered, which is opposite to the banknote storage direction. The tension in the tape 30 will cause it to rotate. Then, the banknotes S stored in the drum housing portion 161 are fed out from the drum housing portion 161 and conveyed from the storage feeding port 151 of the drum type storage feeding device 18 to the transport path 20 side.

When the banknotes S are delivered from the drum type storing and feeding device 18 in this manner, the control unit 15 counts the number of banknotes S to be delivered by detecting the count sensor 181 arranged in the transport path 20 near the storing and feeding outlet 151. do. Then, after the last banknote S among the number of delivered banknotes has passed the banknote detection sensor 171, the control unit 15 stops driving the reel rotation motor 125 at a predetermined timing.

Then, the control unit 15 calculates the number of bills currently stored in the drum-type storage and feeding device 18 by subtracting the number of bills S fed out detected by the count sensor 181, and calculates the calculated number of bills. , and the later-described cumulative winding length obtained by subtracting the number of bills S fed out are stored in the storage unit 16, and the bill feeding operation is completed. That is, the storage unit 16 stores the stored number of banknotes S stored in the drum type storing and feeding device 18 and the accumulated winding length.

<Accumulated winding length>
Here, the cumulative winding length will be explained. The cumulative winding length is the total length of the tape 30 wound around the drum 31. It is the accumulated value of the length of the bills S and the interval between bills S adjacent to each other in the storing and feeding direction. The cumulative winding length is calculated by accumulating the length L2 of the bill S calculated by the bill length detection means 201 and the gap D between the bills S detected by the bill gap detection means 202 .

Specifically, the banknote length detection means 201 of the control unit 15 detects the angular coordinate position of the banknote S (positions of the four corners of the banknote S in FIG. coordinates), the length L2 of the bill S is calculated. Therefore, the length L2 of the banknote S along the storing and feeding direction can be correctly grasped regardless of the posture of the banknote S (whether or not the banknote is in a skewed posture and the degree of the skewed posture). Further, the banknote interval detection means 202 of the control unit 15 detects the interval between the front and rear banknotes S in the transport path 20 based on the detection information of the banknotes S output from the count sensor 181 provided in the transport path 20 as described above. to detect Then, the control unit 15 sets the total length L2 of the banknote S and the interval between the front and back banknotes S as the winding length for one banknote S (pitch for one banknote S). . The control unit 15 accumulates such a winding length (pitch for one banknote S) for all the banknotes S stored in the drum storage unit 161 of the drum type storing and feeding device 18, thereby accumulating winding. Calculate the length.

As described above, the banknote length detection means 201 of the control unit 15 calculates the length L2 of one banknote S based on the angular coordinate position of the banknote S output from the recognition unit 17 . Further, the banknote interval detection means 202 of the control unit 15 calculates the interval between the front and back banknotes S based on the detection information of the banknotes S output from the count sensor 181 . Here, since the identifying section 17 and the counting sensor 181 are both provided in the conveying path 20 , the conveying speed of the bills S passing through the identifying section 17 and the counting sensor 181 is determined by the conveying drive motor that drives the conveying path 20 . , and is not affected by the moving speed of the tape 30 due to the rotation of the drum 31 in the storage direction. Therefore, even if the movement speed of the tape 30 changes due to a change in the outer diameter of the drum housing portion 161 of the drum 31, the banknotes S can stably pass through the identification portion 17 and the count sensor 181 at a predetermined constant speed. pass. Therefore, the length of the banknotes S and the interval between the banknotes S can be accurately calculated using the identification unit 17 and the count sensor 181 .

Such a cumulative winding length corresponds to the outer diameter of the drum housing portion 161 in a state in which the tape 30 and bills S are wound around the drum 31 . That is, if the accumulated winding length is longer than the first length by a predetermined length with respect to the outer diameter of the drum housing portion 161 when the accumulated winding length is the first length, the predetermined length is reached. The outer diameter of the drum accommodating portion 161 is increased by the amount corresponding to .

Here, when the outer diameter of the drum housing portion 161 changes, when the drum 31 is rotated at a constant rotational speed, the peripheral speed of the outer peripheral portion constituting the banknote inlet/outlet 138 of the drum housing portion 161 changes to the drum housing portion If the outer diameter of the drum housing portion 161 is small, the speed will be slow. On the other hand, since the connecting conveying path 157 conveys the banknotes S at a constant speed, the conveying speed of this connecting conveying path 157 and the peripheral speed of the outer peripheral portion constituting the banknote inlet/outlet 138 of the drum storage section 161 must match. For this reason, the controller 15 increases the rotation speed of the drum rotation motor 115, which is a stepping motor, that is, the amount of rotation per unit time. It is changed to a value according to the cumulative winding length so as to slow down as much as possible. Therefore, the control unit 15 stores and manages the cumulative winding length in the storage unit 16 . However, if the cumulative winding length cannot be grasped well, there is a possibility that the speeds of the connecting conveying path 157 and the drum housing portion 161 do not match, causing a conveying failure (jam).

In controlling the rotation speed of the drum rotation motor 115, that is, the amount of rotation per unit time, the weight of the drum storage unit 161 is light if the cumulative winding length is short, and the drum storage unit 161 is light if the cumulative winding length is long. The weight of the portion 161 increases and the load changes. Therefore, it is necessary to appropriately drive the drum rotation motor 115 according to the magnitude of the load. Specifically, when the load is heavy, the drum rotation motor 115 is driven at low speed, and when the load is light, the drum rotation motor 115 is driven at high speed. If the drive pattern is not appropriately selected for the load, the drum rotation motor 115 may be out of step. For this reason as well, the control unit 15 stores and manages the cumulative winding length in the storage unit 16 . This makes it possible to drive the drum 31 with an appropriate drive pattern according to the load currently applied to the drum rotation motor. That is, in order to determine the current load applied to the drum rotation motor 115 when the drum 31 is rotated, the control unit 15 reads out the above-described cumulative winding length from the storage unit 16 and stores the current cumulative winding length. The drum rotation motor 115 is driven with a drive pattern corresponding to the condition.

That is, the load applied to the rotation of the drum 31 is not uniform, but increases or decreases depending on the size and number of banknotes S stored in the drum storage and feeding device 18 . For this reason, the control unit 15 causes the drum rotation motor 115, which is a stepping motor that is the driving source of the drum 31, to be out of step by a control method (driving pattern) according to the load determined for each size of bill S and the number of stored bills. It must be driven properly without For this reason, in the banknote processing apparatus 10 equipped with the drum-type storage and delivery device 18, in order to grasp the amount of banknotes S stored in the drum-type storage and delivery device 18, the stored banknotes are stored in the storage unit 16 together with the number of stored banknotes. The cumulative value of the length of S (cumulative winding length) is stored. In the banknote processing apparatus 10 including a plurality of drum type storage and feeding devices 18, the control unit 15 controls the number of stored banknotes and the cumulative length of the stored banknotes S (cumulative winding length) for each drum type storage and feeding device 18. is stored and used to manage the number of sheets stored and control the rotation of the drum. This makes it possible to appropriately drive the drum rotation motor 115, which is the driving source of the drum 31, according to the cumulative winding length.

As described above, the control unit 15 controls the drum rotation motor 115 , that is, the drum 31 , according to the cumulative winding length stored in the storage unit 16 . For this reason, if the cumulative winding length cannot be grasped well, there is a possibility that the rotation control of the drum rotation motor 115, that is, the drum 31 cannot be properly performed, which causes problems and lowers the processing efficiency. may be connected. That is, if the cumulative winding length that should be stored and managed in the storage unit 16 is different from the actual cumulative winding length, this may cause problems and lead to a decrease in processing efficiency.

On the other hand, in the banknote processing apparatus 10, the cumulative winding length stored in the storage unit 16 is calculated based on the length L2 of the banknotes S correctly recognized by using the identification unit 17 as described above. Therefore, the accumulated winding length can be well grasped. That is, it is possible to improve the accuracy of the cumulative winding length stored in the storage unit 16 . Therefore, the drum 31 can be driven at an appropriate rotational speed, and the occurrence of the above problems can be suppressed or prevented.
Note that the rotational speed of the drum 31 controlled according to the cumulative winding length stored in the storage unit 16 corresponds to the "reference speed" in the aforementioned formula (1).

The cumulative winding length stored in the storage unit 16 changes with the rotation of the drum 31 (accommodation and delivery of banknotes S to and from the drum 31). For this reason, the control unit 15 controls the accumulation stored in the storage unit 16 each time one banknote S is stored in the drum storage and delivery device 18 or each time one banknote S is delivered from the drum storage and delivery device 18. Update the winding length to the latest data. Specifically, the control unit 15 detects the length L2 of the preceding banknote S calculated by the banknote length detection unit 201 and the banknote interval detection unit 202 in the storage operation or delivery operation of the banknotes S by the drum type storage and delivery device 18 . By adding the pitch of one banknote S obtained by summing the interval D between the preceding banknote S and the subsequent banknote S detected by , to the cumulative winding length stored in the storage unit 16, the cumulative winding length to the latest data. As a result, the rotation control of the drum 31 can be appropriately performed based on the latest cumulative winding length.

According to the banknote processing apparatus 10 of the present embodiment described above, the length L2 of the banknote S along the storing and feeding direction is calculated based on the angular coordinate position (see FIG. 3) of the banknote S output from the recognition unit 17. Therefore, the length L2 of the banknote S can be correctly grasped regardless of the posture of the banknote S. As a result, even if the banknote S is wound around the drum 31 with the pitch of one banknote S reduced, it is possible to prevent the subsequent banknote S from colliding with the preceding banknote S. Therefore, it is possible to suppress storage failure of banknotes in the drum. This point will be described below with reference to FIG.

For example, it is conceivable to obtain information on the length of the banknote S by using two count sensors 181 (see FIG. 10) arranged side by side in the width direction of the passage (horizontal direction of the device). In this case, the controller 15 detects one bill S by the two count sensors 181 when the bill S passes through the two count sensors 181 in the transport direction (x-axis direction). The length L1 of the banknote S is obtained based on the time (banknote detection time) and the transport speed of the banknote S.

However, when the banknotes S are conveyed in the conveying path 20 in an oblique posture, as illustrated in FIG. 3, the passing time of the banknotes S (count sensor The bill detection time by the count sensor 181 may be measured shorter than the time to pass through 181). That is, the length L1 of the banknote S acquired based on the banknote detection time by the count sensor 181 may become shorter than the actual length L2 of the banknote S. In this case, the drum 31 is driven at a rotation speed slower than the originally required rotation speed, or the data for driving control of the drum 31 stored in the storage unit 16 (for example, the cumulative winding length) is not appropriate. A problem such as not If such a problem occurs, when the banknotes S are stored in the drum-type storage and feeding device 18, an abnormality in which the subsequent banknote S collides with the preceding banknote S (a collision jam error of the banknote S) may be induced, resulting in storage failure. There is

On the other hand, in the present embodiment, the length L2 of the banknote S can be correctly grasped based on the angular coordinate position of the banknote S regardless of the posture of the banknote S. As a result, the drum 31 can be driven at an appropriate rotational speed, and appropriate drive control data for the drum 31 (for example, cumulative winding length) can be stored in the storage unit 16 . As a result, even if the banknote S is wound around the drum 31 in a state where the pitch of one banknote S is reduced when the banknote S is stored in the drum type storing and feeding device 18, a collision jam error of the banknote S does not occur. can be suppressed or prevented.

Further, according to the banknote processing apparatus 10 of the present embodiment, the controller 15 controls the length L2 of the preceding banknote S calculated by the banknote length detection means 201 in the storage operation of the banknote S by the drum storage and feeding device 18 . , and the interval D between the preceding banknote S and the subsequent banknote S detected by the banknote interval detection means 202 , the rotational speed of the drum 31 is controlled. Specifically, the controller 15 calculates the rotation speed (winding speed) of the drum 31 by the calculation formulas (1) to (3) described above. As a result, it is possible to reliably wind the banknotes S around the drum 31 so that the subsequent banknotes S do not collide with the preceding banknotes S with the space between the banknotes S as close as possible.

Further, according to the banknote processing apparatus 10 of the present embodiment, the cumulative winding length stored in the storage unit 16 is calculated based on the length L2 of the banknotes S that has been correctly grasped by using the identification unit 17. Therefore, it is possible to improve the accuracy of the cumulative winding length. Thereby, the drum 31 can be driven at an appropriate rotational speed. As a result, there is an effect that the interval between bills S stored in the drum 31 can be reduced.

Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

In the present invention, for example, when the interval D between the banknotes S detected by the banknote interval detection means 202 is equal to or less than a predetermined value (for example, 61 mm), the control unit 15 causes the drum storage and feeding device 18 to store the banknotes S. , based on the length L2 of the preceding banknote S calculated by the banknote length detection means 201 and a predetermined uniform value (for example, 5 mm) as the interval between the preceding banknote S and the following banknote S, 31 may be controlled. Further, when the interval D between the banknotes S detected by the banknote interval detection unit 202 exceeds a predetermined value, the preceding banknote calculated by the banknote length detection unit 201 during the storage operation of the banknotes S by the drum storage and feeding device 18 The rotation speed of the drum 31 may be controlled based on the length L2 of S and the interval D between the preceding banknote S and the subsequent banknote S detected by the banknote interval detection means 202 .

Here, when the banknotes S are continuously conveyed from the same location (for example, the deposit unit 11) toward the same drum storage and delivery device 18, the interval D between the banknotes S tends to be less than or equal to a predetermined value. Variation in interval D between banknotes S is small. Therefore, when the interval D between the banknotes S is equal to or less than a predetermined value, even if a uniform specified value is used as the interval between the banknotes S in the rotation control of the drum 31, no problem occurs.

On the other hand, when banknotes S are sorted and conveyed from the same location (for example, the drum type storage and feeding device 18 (A)) toward a plurality of locations (for example, a plurality of drum type storage and feeding devices 18 (B)), The interval D between the banknotes S transported toward the predetermined drum type storing and feeding device 18(B) tends to exceed a predetermined value. Then, the banknotes S are intermittently transported toward the predetermined drum storage and delivery device 18(B), and the variation in the interval D between the banknotes S transported to the predetermined drum storage and delivery device 18(B) increases. Cheap. Therefore, when the interval D between the banknotes S exceeds a predetermined value, it is not preferable to use a uniform specified value as the interval between the banknotes S in controlling the rotation of the drum 31 .

In the above-described configuration, the banknotes S are continuously conveyed and stored in the drum type storing and feeding device 18 in a state in which the interval D between the front and rear banknotes S is within a predetermined value (that is, a state in which the interval D between the banknotes S is narrowed). When the length L2 of the banknote S is calculated by the banknote length detection means 201, accurate length information (actually measured value) is used, and a uniform specified value is used for the interval between the banknotes S. By doing so, it becomes possible to shorten the processing time in the control unit 15 in controlling the rotational speed of the drum 31 . By shortening the processing time, it is possible to correctly control the rotation of the drum 31 even if the transport speed of the bills S is increased.

On the other hand, in a state where the interval D between the bills S before and after exceeds a predetermined value (that is, when the interval D between the bills S is large), when the bills S are continuously conveyed and stored in the drum storage and feeding device 18, , the length of the banknote S is calculated by the banknote length detection means 201 to use accurate length information (actually measured value), and the interval D between the banknotes S is the measured value detected by the banknote interval detection means 202. can be used to obtain an accurate pitch for one banknote S. This makes it possible to drive the drum 31 at an appropriate rotational speed. In particular, the drum 31 can be driven at an appropriate rotational speed even if the intervals between the banknotes S are uneven due to intermittent transport of the banknotes S toward the drum storage and delivery device 18 .

In the present invention, the method in which the control unit 15 updates the cumulative winding length stored in the storage unit 16 to the latest data each time one banknote S is stored in the drum type storage and feeding device 18 is the method described above. It is not limited to the method described in the form.
In the present invention, for example, when the interval D between the banknotes S detected by the banknote interval detection means 202 is equal to or less than a predetermined value (for example, 61 mm), the control unit 15 causes the drum storage and feeding device 18 to store the banknotes S. In the operation, the length L2 of the preceding banknote S calculated by the banknote length detection means 201 and the uniform specified value (for example, 5 mm) preset as the interval between the preceding banknote S and the following banknote S are added together. By adding the pitch of one bill S to the accumulated winding length stored in the storage unit 16, the accumulated winding length may be updated to the latest data. Further, when the interval D between the banknotes S detected by the banknote interval detection means 202 exceeds a predetermined value, as described in the above embodiment, the control unit 15 causes the drum storage and delivery device 18 to store the banknotes S. In operation, a banknote S length obtained by summing the length L2 of the preceding banknote S calculated by the banknote length detection means 201 and the interval D between the preceding banknote S and the subsequent banknote S detected by the banknote interval detection means 202 is calculated. By adding the pitch for each sheet to the cumulative winding length stored in the storage unit 16, the cumulative winding length may be updated to the latest data.

In the method described above, the banknotes S are continuously conveyed and stored in the drum storage and delivery device 18 in a state where the interval D between the front and rear banknotes S is within a predetermined value (that is, a state where the interval D between the banknotes S is narrowed). When the length L2 of the banknote S is calculated by the banknote length detection means 201, accurate length information (actually measured value) is used, and a uniform specified value is used for the interval between the banknotes S. By doing so, it is possible to shorten the processing time in the control unit 15 in updating the data of the accumulated winding length. By shortening the processing time, it is possible to correctly control the rotation of the drum 31 even if the transport speed of the bills S is increased.

On the other hand, in a state where the interval D between the bills S before and after exceeds a predetermined value (that is, when the interval D between the bills S is large), when the bills S are continuously conveyed and stored in the drum storage and feeding device 18, , the length L2 of the banknote S is calculated by the banknote length detection means 201 to use accurate length information (actually measured value). By using the value, a more accurate pitch for one bill S can be obtained. As a result, the accuracy of the cumulative winding length stored in the storage unit 16 can be further improved, and the drum 31 can be driven at a more appropriate rotational speed.
