Description

The present invention relates to a paper sheet processing apparatus that discriminates and sorts paper sheets such as securities, and more particularly to a paper sheet processing apparatus that stably accumulates and seals regardless of the quality and state of the paper sheets. About.

A paper sheet processing apparatus that processes paper sheets such as securities takes out and transports the paper sheets that are put in a batch one by one, and the type of the paper sheet (hereinafter referred to as “the paper sheet”). This is the result of this discrimination: discrimination (referred to as ticket type), transport direction discrimination, authenticity discrimination (true or counterfeit), and damage discrimination (reflowable or non-reflowable) Based on the above, it is a device for aligning the ticket type and the front and back, and stacking or stacking in a stacking section having a plurality of stackers. The stacking unit counts the number of sheets and classifies them by designated ticket type, front / back, authenticity, and direction. Further, in the sealing unit, the paper band is wound (sealed) every specified number of sheets (for example, 100 sheets). In a conventional paper sheet processing apparatus, a paper sheet that can be sealed based on a result determined by the paper sheet determination apparatus is selected as the quality of the paper sheet (hereinafter referred to as a ticket quality) and the state of the paper sheet. Regardless of whether it is collected in the temporary storage box of the sealing part and compressed with a uniform pressing force,

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic cross-sectional view of a paper sheet processing apparatus according to Embodiment 1 of the present invention. This paper sheet processing apparatus includes a paper sheet processing unit 1 and a main control unit 500. The main control unit 500 is provided with an operation display unit 502. By the operation of the operator from the operation display unit 502, setting of a transaction method such as depositing work and organizing work, and processing of processed paper sheets are performed. The sealing device 4 that performs sorting processing such as stacking, the cassette assignment setting that sets the ticket type to be processed by the stacking devices 57 to 62, and the damage level setting that is the paper sheet discrimination level are performed. After this setting, the plurality of types of paper sheets P supplied to the supply unit 10 are taken out and conveyed one by one at regular intervals, and are determined by the paper sheet determination device 19. Based on the result of discrimination by the paper sheet discriminating device 19, the temporary stacker 42B of the sealing device 4 set by the cassette assignment setting,
43B or the cassettes 57D to 62D of the stacking devices 57 to 62.

In addition, at the end of the transaction of the set business, a transaction separation process is performed at the end of each business. Furthermore, a balance process is performed in which transaction counts are aggregated in units such as the end of a day's business.

The depositing operation refers to a plurality of types of paper sheets P whose total amount is known in advance, and the paper sheet processing apparatus 1
Is used to check that the amount counted by the paper sheet processing apparatus 1 is correct and is registered in the system. In addition, the paper sheet P processed by this work is sealed by the sealing device 4, or each cassette 57D of the stacking devices 57-62.
Integrated in 62D.

The sorting work is a work in which the counting is not registered in the system in the depositing work. The purpose is not to count the ticket types that have been traded, but in more detail, for example, the ticket types that have been counted once in the deposit operation, for example, in the cassettes 57D to 62D of the stacking devices 57 to 62 for each sheet transport direction. Used for storage and sealing.

The cassette assignment setting is to set a ticket type to be sealed by the sealing device 4 and a ticket type to be stored in each of the cassettes 57D to 62D of the stacking devices 57 to 62.

For example, in the case of deposit processing, normally, a ticket type with a large circulation amount is first assigned to a sealing device, and bundled (bundled every 100 sheets) at the same time while deposit processing is performed. If the number of processing ticket types can be connected, the above processing ends. However, if there are 7 types of assigned ticket types and only one sealing device is connected as shown in the figure, distribution is possible. A method such as assigning the top one ticket type having a large amount to the sealing device 4 and assigning the remaining six ticket types to the cassettes 57D to 61D of the stacking devices 57 to 61 is used.

The correctness level setting is to set a threshold level that is classified into a correctable ticket that can be recirculated and a non-reflowable ticket. Details will be described later.

The transaction delimiter process is a process in which, after the end of each transaction, for example, when a completion button (not shown) provided on the operation display unit 502 is pressed, the sheets stacked in the stacking devices 57 to 62 are stored in each cassette 57D. In the processing stored in ˜62D, each cassette storing paper sheets is replaced with an empty cassette by the operator.

Here, the conveyance direction when the paper sheet P is conveyed will be described. Paper sheet P is a table (F
ace: front side up), back side (Back: back side up), positive (forward:
There are four types: paper sheet front / back printing upright) and reverse (reverse: paper sheet front / back printing upside down), FF (front), FR combining these (
Four types of transport directions are formed, which are composed of (reverse), BF (reverse), and BR (reverse).

FIG. 3 is a schematic diagram for explaining the operation of the sealing unit 4 of this embodiment. FIG. 4 is a flowchart for explaining processing of the sealing unit shown in FIG. FIG. 5 shows a front / back / front / reverse sorting subroutine used in the process of FIG. FIG. 6 is a diagram showing the transport direction of the paper sheets to be converted as a result of the front / back / front / reverse sorting process shown in FIG. The operation of the sealing unit will be described below with reference to FIGS. 3, 5, and 6 based on the flowchart of FIG.

When the paper sheet P in which a plurality of ticket types are mixed is supplied to the supply unit 10 by the operator, the supplied paper sheet P is taken out one by one by the take-out roller 14 and supplied to the transport path 16.
The supplied paper sheet P is conveyed to the conveyance correction unit 210 (S1).

The conveyance correction unit 210 performs conveyance correction. The conveyance correction unit 210 corrects conveyance skew and conveyance position deviation. The paper sheet P whose transport pitch is corrected is sent to the paper sheet discrimination device 19.

The paper sheet discriminating device 19 discriminates the paper type of the paper sheet P conveyed by the paper sheet discriminating unit 20, the conveyance direction, the authenticity, and the correct paper sheet (S3).

If it is determined as a fake or damaged ticket as a result of the paper sheet discrimination, the transport control unit 26 rotates the sorting gate G1 to the right in order to stack the reject paper sheet P in the reject stacking unit 80. (S4). As a result, the reject paper sheet P passes through the sorting gate G1 and is accumulated in the reject accumulation unit 80 (S5).

In addition, when the paper sheet is determined to be a genuine note (correct or non-performing), the front and back sides or the reverse side of the paper sheet P is arranged in the transport direction designated by the main control unit 500. The “reverse sorting” subroutine process is performed (S6).

FIG. 5 shows the “front / back / front / back assortment” subroutine. It is determined whether the transport direction designation at the time of stacking or storage by the main control unit 500 is one-direction assortment designation or front-and-back assortment designation (S23).

In the case of unidirectional assortment designation, the switchback reversing unit 3 and the front / back reversing unit 9 are operated according to the result of the paper sheet discrimination of the paper sheet P by the paper sheet discrimination device 19, and the switchback based on FIG. Inversion processing and front-back inversion processing are performed (S24).

For example, when aligning in the front FF direction, the transport direction is converted as follows.
Supplied transport direction: Front FF → Transport direction in which nothing is supplied: Front reverse FR → A process + B process Transport direction supplied: Reverse BF → B process Feed direction: Reverse reverse BR → A Process A process: Switchback inversion process B by the switchback inversion unit 3 B process: Front / back inversion process A process by the front / back inversion unit 9 + B process: Both the A process and the B process are performed

In the case of the front / back assortment designation, if the result of the paper sheet discrimination of the paper sheet P by the paper sheet discrimination device 19 is front conveyance (front normal FF, front reverse FR), no processing is performed. End processing (
Yes in S25). On the other hand, if the result of paper sheet discrimination is reverse transport (backside normal BF, reverse side BR),
A front / back reversing process (B process) for passing the front / back reversing unit 9 and reversing the front and back of the paper sheet is performed (S2).
6). In this case, the transport direction is converted as follows.
(Front-back reverse processing by the front-back reverse part 9)
Supplied transport direction: front FF → Do nothing Supply transport direction: front reverse FR → Do nothing Supplied transport direction: reverse BF → front FF
Supply direction: reverse reverse BR → front reverse FR

With the above processing, the sheet P having the same transport direction is subjected to the sealing processing after step S7 shown in FIG.

The “front / back / front / reverse sorting” subroutine process is terminated, and it is determined whether or not the paper sheet P having the same transport direction is a sealing ticket type (S7).

As a result of the determination in step S7, when the type is other than the sealing ticket type, the conveyance control unit 26 rotates the sorting gate G3 to the left (counterclockwise), and further rotates the sorting gates G4 to G8 to make the paper. The leaves P are stored in any of the storages 57D to 62D of the stacking units 57 to 62 designated for each ticket type (S8 to S9).

As a result of the determination in step S7, in the case of a sealing ticket type, the sorting gates G3 and G12 are set to an initial state in order to perform sealing processing. That is, the sorting gate G3 is set to rotate rightward (clockwise) so that the paper sheet P is conveyed to the sealing unit 4, and the sorting gate G1.
2 is rotated to the left (counterclockwise) so that the sheets P are stacked on the first stacking section 42 of the sealing section 4 (S10). In parallel with this process, paper strip printing of the sealing ticket type is started (
S11).

Here, the paper strip portion 46 will be described. The paper strip 46 can be color printed on the surface,
The back surface is composed of roll paper that can be thermally bonded, and is set in a rotatable roll paper holder 46A.

When the paper sheet P of the sealing ticket type is detected in step S7, the printing unit 47 can distinguish the ticket type, for example, a pattern, a ticket type, a correct / damaged ticket, a total amount, A sealing ticket type attribute such as a bank name (a matter for identifying a sealed paper sheet) is printed on the paper band 46B by an inkjet method.

The sealing control unit 400 determines whether or not the number of paper sheets P loaded in the temporary stacking unit 42B constituting the first stacking unit 42 of the sealing device 4 has reached 100 (S12). If the result of determination in step S12 is that it has not reached 100 sheets, it waits until it reaches 100 sheets (No in S12).
).

In this way, when the number of paper sheets P in the temporary stacking box 42B reaches 100 sheets, the paper sheets P that are continuously conveyed are stacked in the temporary stacking box 43B of the second stacking unit 43. The gate G12 is rotated to the right (S16). Further, the paper sheet P that has reached 100 sheets in the temporary stacking box 42B is sealed in the band winding processing routine (S13 to S15).

That is, in the belt winding processing routine, the paper sheet 45 that has reached 100 sheets is sandwiched between the backup plate 42C and a paper sheet holder (carrier clamp, which will be described later) (paper sheet restraining mechanism).
The first vertical conveying path 44A is lowered to the lower stop position in the direction of the arrow A41 (S13).
.

Next, the paper sheet 45 sandwiched between the backup plate 42C and the paper sheet holder is moved to the transport carrier 44D.

Further, the transport carrier 44D loaded with the paper sheets 45 passes through the lateral transport path 44C by the arrow A44 shown in the figure.
The paper sheet 45 is delivered to the sealing tray 49 (S14).

The transport carrier 44D that has become empty stands by, for example, at the lower stop position of the second vertical transport path 44B in order to transport the next 100 sheets.

Next, the paper sheets 45 of the sealing tray 49 are wound (sealed) with the paper band 46C that has been subjected to the paper band printing in step S11, with the paper sheets 45 as a lump in the paper winding section 48 (S15). In this way, the small bundle wrapped by the printed paper band is released from the sealing device 4 (
S22).

Next, the operation of the second stacking unit 43 will be described. The sealing controller 400 determines whether or not the number of sheets P accumulated in the temporary stacker 43B of the sealing device 4 has reached 100 as in step S12 (S17). If the result of determination in step S17 is that the number has not reached 100, 10
Wait until the number is zero (No in S17).

In this way, when the number of paper sheets P in the temporary stacking box 43B reaches 100 sheets, the sorting gate G12 is rotated to the left in order to stack the continuously transported paper sheets P in the temporary stacking box 42B. (S21). Further, the paper sheets P accumulated in the temporary accumulation box 43B are sealed in the band winding processing routine (S18 to S20).

In the belt winding process routine, as in step S13, the paper sheet 45 that has reached 100 sheets is sandwiched between the backup plate 43C and a paper sheet holder (carrier clamp, which will be described later), and the second vertical conveyance path 44B is in the direction indicated by the arrow A43 in the figure. Is lowered to the stop position (S18).

Next, similarly to step S14, the paper sheet 45 sandwiched between the backup plate 43C and the carrier clamp (paper sheet restraining mechanism) and lowered to the stop position of the second vertical transport path 44B is moved to the transport carrier 44D.

Further, the transport carrier 44D loaded with the paper sheets 45 is moved along the horizontal transport path 44C by the arrow A44 shown in the figure.
The sheet 45 is transferred to the sealing tray 49 (S19).

The transport carrier 44D that has become empty stands by, for example, at the lower stop position of the first vertical transport path 44A in order to transport the next 100 sheets.

Next, as in step S15, the paper sheet 45 of the sealing tray 49 is fed by the paper winding unit 48.
5 is bundled (sealed) by the paper band 408 that has been printed with the paper band in step S11.

In this way, the small bundle sealed with the color-printed paper band is released from the sealing device 4 (S22).

FIG. 7 is a diagram illustrating conversion values based on the ratio of the thickness of the paper sheet in various states to the standard thickness of the paper sheet. FIG. 8 is a diagram illustrating the shape of the paper sheet group when the paper sheets are stacked in the temporary stackers 42B and 43B. Hereinafter, the conversion values will be described with reference to FIG.

The case where the state level of the paper sheet is good indicates, for example, a new paper sheet that has been newly issued and has little time elapsed, and has a low conversion value ratio. In this case, the case where the quality of the sheet is better than that in the case where the state level of the paper sheet is medium. In this case, a value with a low conversion value is used.

The case where the state level of the paper sheet is “medium” means a so-called distribution ticket, and the case where the state level of the paper sheet is an intermediate level, and an intermediate value is used as the conversion value.

The case where the state level of the paper sheet is bad is a so-called non-performing paper, which means that the quality of the paper sheet is poor compared to the case where the state level of the paper sheet is medium, and the ratio of the conversion value is high. .
