An object of the present invention is to provide a paper sheet processing apparatus.

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

  FIG. 1 is a schematic configuration diagram of a paper sheet processing apparatus 100 including a paper sheet discriminating apparatus 19 according to an embodiment of the present invention. FIG. 2 shows the configuration of the paper sheet discriminating apparatus 19 shown in FIG. FIG. 3 is a block diagram for explaining the operation of the paper sheet discriminating apparatus 19 shown in FIG. Hereinafter, the sheet processing apparatus 100 will be described with reference to FIGS. 1 to 3.

  The paper sheet processing apparatus 100 includes an operation unit 550 and a paper sheet processing machine 1.

  The operation unit 550 obtains a business content instruction performed by the paper sheet processing machine 1, a transaction content specification based on the instructed business content, and a transaction result obtained by the paper sheet processing machine 1, and the obtained result is obtained. It transmits to the host system which is not illustrated. The paper sheet processing apparatus can be used off-line, in which case it is used without being connected to a host system.

  The operation unit 550 includes an input unit 551 and an operation display unit 552. The type of the paper sheet to be processed (ticket type), the damage determination level for determining whether the paper sheet is correct, accumulation, or application. The operator can set the type of ticket to be sealed.

  The input unit 551 is connected to a keyboard or a mouse and is used for data input.

  The operation display unit 552 guides the operator to operate the paper sheet processing machine 1, and displays the input data so that the operator can check.

  The paper sheet processing machine 1 is connected to the operation unit 550 via an interface 501. Hereinafter, the configuration of the paper sheet processing machine 1 will be described in order from the supply unit 10 that supplies the paper sheet P.

  The supply unit 10 has a supply table 11. When a paper sheet P is set on the supply table 11 and a take-out start button (not shown) is turned on, the supply unit 10 is pressed by the take-out roller 5. The paper sheets P are sequentially taken out one by one from the most advanced paper sheets of the paper sheet P with a certain interval as the take-out roller 5 rotates.

  The conveyance path 16a holds a plurality of paper sheets P with a belt facing the conveyance surface. The paper sheet P is transported by driving the transport roller around the transport belt.

  The branch gate G1 is, for example, a gate that distributes a rejection ticket and a processing ticket. The rejected ticket is a paper sheet discriminating device (paper sheet discriminating means) 19 that discriminates the paper sheet P. As a result, the paper sheet P cannot be discriminated due to a fake ticket, broken, torn or skewed. The paper sheet P identified as “ticket”. When the conveyance control unit 26 receives this determination result, the rejected ticket is stacked in the rejected ticket stacking device 30 by rotating the branch gate G1 to the right (clockwise).

  Further, the processing ticket means that the paper sheet P discriminated by the paper sheet discriminating device 19 is a genuine note and a genuine note, or a genuine note and a non-performing note. When the conveyance control unit 26 receives the determination result, the conveyance control unit 26 rotates the branch gate G1 to the left (counterclockwise) to sort the paper sheet P.

  The reversing processing unit 9 has a front / back reversing function, and reverses the front and back of the paper sheets according to the direction in which the paper sheets P are arranged. The branch gate G2 is a front / back inversion branch gate. Based on the determination result of the transport direction of the paper sheet P determined by the paper sheet determination device 19, the paper sheet P is rotated to the left (clockwise) when the front / back inversion is necessary, and the paper sheet P is moved by the arrow A6 shown in the drawing. The front-back inversion part 9 to be shown is passed. Further, when the front / back inversion is not required, the branch gate G2 is rotated to the right side, and the paper sheet P is conveyed in the direction indicated by the arrow A4 in the drawing. For example, when the conveyance direction is reverse (BF), it is reversed by the front / back reversing unit 9 to become front (FF).

  The branch gate G3 is a branch gate that branches the transported paper sheet P from the transport path 16a to the sealing device 40 or the stacking unit 50. When the paper sheet P to be transported is a ticket type designated to be sealed by the operation unit 550, the transport control unit 26 rotates the branch gate G3 to the right (clockwise), and removes the paper sheet P. It is conveyed in the direction of the illustrated arrow A7 where the sealing device 40 is provided. Further, the paper sheets P of other ticket types are sorted so as to be stacked on the stacking devices 57 to 62 from the branch gate G3 via the branch gates G4 to G8.

  The sealing device 40 and the stacking device 50 are provided with an impeller stacking device that stacks the paper sheets P at the end of the transport path in order to separate from the transport path where the paper sheets P are transported.

  For example, in the case of the accumulating device 57, the impeller accumulating device includes an impeller 57a, a temporary accumulating unit 57b, a shutter 57c, a cassette 57e, and a pusher (not shown) for assisting accumulating.

  The impeller 57a has a plurality of blades incorporated around the rotation shaft, and rotates in synchronization with the conveyance of the paper sheet P so that the conveyed paper sheet P can be received between the blades. Yes. By using the impeller 57a, the kinetic energy of the paper sheet P conveyed at high speed is absorbed, and the paper sheet P is accumulated in the temporary accumulation box 57b while being aligned.

  The temporary stacker 57b used in the stacking device 57 is provided with a shutter 57c, and the paper sheets P are stacked on the shutter 57c. When the paper sheets P accumulated on the shutter 57c are full, for example, when there is a work end instruction (not shown), the shutter 57c is opened, and the paper sheet P is used as a stacker provided below the shutter 57c. Falls on the backup plate 57d provided in the cassette 57e.

  The sealing device 40 includes a first stacking unit 42, a second stacking unit 43, a transport unit 44, a paper band unit 46, a band feeding unit 47, and a band winding unit 48. In the present embodiment, the case where the sealing device 40 includes the first stacking unit 42 and the second stacking unit 43 will be described. If necessary, a plurality of sets of these two stacking units may be paired. It may be used.

  Since the first stacking unit 42 and the second stacking unit 43 are both configured in the same manner, the configuration of the first stacking unit 42 will be described and the description of the second stacking unit 43 will be omitted.

  The first stacking unit 42 includes a branch gate G12 for branching the paper sheets from the sealing transport path 40a, a transport path 40b for transporting the sorted paper sheets P, and a paper sheet sent from the end of the transport path 40b. Are provided, a temporary stacker 42b for accumulating the paper sheets P received by the impeller 42a, and a pusher (not shown) for pressing the accumulated paper sheets P. Hereinafter, each part structure of the sealing apparatus 40 is demonstrated.

  The temporary stacker 42b counts the transported paper sheets P and reaches 100 sheets, and switches the switching gates G12 and G13 to stack the transported paper sheets P in the temporary stacker 43b. Thereafter, the 100 sheets Pb accumulated in the temporary accumulation box 42b are sealed. The sealing operation will be described below.

  The 100 sheets stacked in the temporary stacker 42 b are delivered to the transport carrier 44. The transport carrier 44 is transported longitudinally and laterally as indicated by the arrows in the figure, and delivers 100 sheets Pb to the belt winding unit 48.

  When the paper strip 46a supplied from the paper strip portion 46 is fed by the belt feeding portion 47 and reaches the belt winding portion 48, the belt winding portion 48 is transferred to the paper winding portion P. A predetermined part of the 100-sheet paper is wound around using a band. In this way, a small bundle H made of 100 sheets of paper wound up is formed.

  The small bundle H formed by the band winding portion 48 is stored in the cassette 63d of the small bundle stacking device 63. The cassette 63d is accommodated by opening the shutter 63c and the entrance door of the bundle accumulating device 63, putting the bundle H into the cassette 63d, and pushing it into the inside with a push rod (not shown). The state of the bundles H accumulated in this way is shown in FIG.

  FIG. 2 shows the configuration of the paper sheet discriminating apparatus 19 shown in FIG. The paper sheet discrimination device 19 includes a main detection control unit 20 and a plurality of detection units.

  The main detection control unit 20 includes an MCPU (Main Central Processing Unit) 20a serving as a first control unit that controls the entire paper sheet discriminating apparatus, a storage unit 20b serving as a first storage unit, and communication control serving as a communication control unit. Unit 20c is provided, and is configured to be communicable with detection units 21, 22, as detection means for detecting paper sheets. Based on the detection result transmitted from each detection unit, the paper sheets are integrated. Discriminate.

  The detection units (detection means) 21, 22,... Are, for example, a shape detection unit that detects the shape of the conveyed paper sheet P, a ticket type detection unit that detects a ticket type from the color and pattern of the surface of the paper sheet, Damage detection unit for detecting paper sheet damage, magnetic detection unit for detecting magnetic material of printing ink on paper sheet, fluorescence detection unit for detecting fluorescence of ink, thickness of paper sheet is detected It consists of a thickness detection unit.

  The main detection control unit 20 is connected to the main control unit 500. The main control unit 500 is connected to the operation unit 550. Accordingly, when an operator inputs a processing ticket type to be processed from the operation unit 550, an FPGA (Field Programmable Gate) that constructs a processing board to be used based on the input ticket type information and hardware to be applied to the processing board. Array) data and software information using the hardware are transmitted from the storage unit 20b to the processing substrate to be applied.

  For example, when the operator designates the processing of Japanese banknotes, the shape detection data of four types of bills (1,000 yen, 2,000 yen, 5,000 yen, 10,000 yen) is converted into a shape detection unit, ticket type detection data, correct / incorrect Detection data, magnetic detection data, fluorescence detection data, thickness detection data, and the like are transmitted to the processing substrate to which they are applied.

  The SCPU (Sub Central Processing Unit) of each detection unit 21, 22,... Stores the detection configuration data received from the main detection control unit 20 in each designated area of the storage unit provided in the processing board.

  Since the detection configuration data of each of the detection units 21, 22,... Is stored in the storage unit 20b managed by the MCPU 20a, the SCPU 21a that configures each detection unit can refer to the storage unit 20b. It may be. With such a configuration, there is no need to perform transmission from the MCPU 20a to the SCPU 21a, and processing can be performed at high speed. However, since this method extends the data bus of the MCPC, the condition is that the processing board of each detection unit and the position of the MCPU 20a are arranged at a position where they can communicate. Therefore, when the distance between the main detection control unit 20 and the detection unit 21 becomes longer than the communicable position, communication is performed through the communication control unit 20c described later. The present invention is configured to be able to cope with both of these.

  In order to simplify the description, for example, a case where the shape detection unit corresponds to the detection unit 21 and the ticket type detection unit corresponds to the detection unit 22 will be described.

  It is connected to a sensor A 21 e for detecting the shape through the input / output part of the detection unit 21. This sensor A21e has a CCD (Charge Coupled Device) arranged in a direction perpendicular to the conveying direction of the paper sheet P, and images the transmitted light when the paper sheet P1 passes through. The imaged data is captured by the processing board A.

  The processing board A includes SCPU 21a as second control means for processing the processing board, storage section 21b as second storage means for controlling the operation of the SCPU 21a, and hardware that operates under the control of the SCPU 21a. An FPGA 21c as hardware means for performing the communication and a communication control unit 21d capable of communicating with the main detection control unit 20 as necessary are provided.

  The SCPU (second control means) 21a is a CPU that performs arithmetic processing on the shape detection data acquired by the sensor A21e with respect to the transmitted light related to the paper sheet P1 conveyed in the direction indicated by the arrow A1.

  The storage unit 21b includes a boot program necessary for the SCPU 21a to operate in an initial state such as power-on, a shape detection program provided by the main detection control unit 20, a shape detection hardware program of the FPGA 21c, and a shape detection determination parameter. Saved.

  The shape detection hardware program is downloaded to the FPGA 21c.

  As described above, the communication control unit 21d is effective when the processing substrate A of the detection unit 21 and the position of the MCPU 20a are not arranged at a communicable position. In this case, for example, when a LAN line is used as a communication means or when USB communication is possible, the determination is made based on the communication time and communication amount in the environment.

  The detection unit 22 is configured in the same manner as the detection unit 21. For example, a case where the detection unit 22 performs ticket type detection will be described as an example.

  The SCPU (second control means) 22a is a CPU that performs arithmetic processing on the bill type detection data obtained by capturing the reflected light and transmitted light on the front or back surface of the conveyed paper sheet P2 with the sensor 22e.

  The storage unit (second storage unit) 22b includes a boot program necessary for the SCPU 22a to operate in an initial state such as power-on, a ticket type detection program transmitted from the main detection control unit 20, and a ticket type of the FPGA 22c. A detection hardware program and a ticket type detection / discrimination program are stored.

  The above-described ticket type detection hardware program is downloaded to the FPGA 22c.

  Since the communication control unit 22d is used in the same manner as the communication control unit 21d of the shape detection unit, description thereof is omitted.

  Similarly, a plurality of detection units are used in accordance with the processing content for processing paper sheets to constitute a paper sheet discrimination device.

  The detection result by each detection unit configured as described above is transmitted to the main detection control unit through the bus 19a.

  The MCPU 20a of the main detection control unit 20 performs comprehensive determination based on detection data received from the detection units 21, 22, and so on. For example, in the case of shape detection, the values of the width, length, inclination, tear, and cut size of the paper sheet P1 are received, and these values are within the reference values set for each ticket type. It is determined whether it exists. Further, in the case of ticket type detection as described above, it is determined whether the color or pattern of the front and back surfaces of the paper sheet P2 matches the ticket type to be processed. This discriminating method can be performed using a well-known technique such as a pattern matching method and is not the object of the present invention.

  FIG. 3 is a block diagram for explaining operations of the main control unit 500, the main detection control unit 20, and the detection unit 21 of the paper sheet discriminating apparatus 19. Here, in order to simplify the description, a case where one detection unit 21 is connected is shown.

  In the paper sheet discriminating apparatus configured as described above, it is assumed that the hardware and detection contents inside the paper sheet discriminating apparatus are changed. This corresponds to a case where, for example, the apparatus is an apparatus that sorts banknotes, a ticket change is performed, and the hardware of the paper sheet discriminating apparatus and the process thereof are significantly changed. .

  First, ticket type information corresponding to a ticket change is notified from the main control unit 500 via the communication control unit 20c of the main detection control unit 20 by the operator.

  Next, the MCPU 20a of the main detection control unit 20 stores the ticket type information transmitted from the main control unit 500 in the storage unit 20b, and based on the stored ticket type information, the detection program and detection in each detection unit. The detection configuration data including the FPGA program (detection HW / FPGA program) and detection parameters constituting the hardware is selected.

  Next, the configuration data selected for each detection unit in this way is transmitted to each detection unit.

  Next, each detection unit stores the detection configuration data transmitted from the main detection control unit 20 in a corresponding memory area of the detection unit.

  For example, when the detection unit 21 is a shape detection unit as described above, the shape detection program stored in the storage unit 20b of the main detection control unit 20 is stored in the SCPU program area of the storage unit 21b1 of the detection unit 21, and the shape detection program. Used as The shape detection HW / FPGA program is stored in the FPGA program area of the storage unit 21b2 and used as a shape detection FPGA program. Furthermore, the shape detection parameter is stored in the determination parameter area of the storage unit 21b2, and is used as the shape detection determination parameter.

  Next, the SCPU accesses the FPGA 21c, transfers the FPGA program, or switches the memory access right so that the FPGA 21c can access the FPGA program area of the storage unit 21b2. By this operation, hardware reconstruction by the FPGA is performed. As a result, the FPGA functions as hardware for shape detection.

  Similar processing is performed for the other detection units. When all the processes are completed, the sheet processing apparatus is ready for operation.

  Next, the start switch (not shown) of the paper sheet processing apparatus is turned on, and the taking out of the paper sheet P is started. For example, when the paper sheet P is detected by the shape detection sensor 21e, the detected output signal is output to the sensor processing circuit 21f. The shape signal detected by the shape detection sensor 21e is an analog signal obtained by detecting the transmitted light of the paper sheet P with an image sensor such as a CCD as described above, and outputs this analog signal to the sensor processing circuit 21f.

  The sensor processing circuit 21f converts the analog signal input from the shape detection sensor 21e into digital data by an A / D converter (Analog to Digital converter).

  The A / D converted digital data is calculated by a shape detection program built in the storage unit 21b1 of the SCPU 21a, and the width, length, inclination, tearing, and cutting of the paper sheet P described above are detected. .

  Further, the detected data is compared with a discrimination level given by the shape detection parameter. The data compared with the discrimination level is transmitted to the main detection control unit 20 by the SCPU 21a.

  The main detection control unit 20 performs comprehensive determination based on the detection results from the liquid detection unit 21 and the detection results from other detection units. The detection result determined in this way is transmitted to the main control unit 500.

  The main control unit 500 transmits the detection result from the main detection control unit 20 to the transport control unit. As described above, the transport control unit sets the sorting destination based on the determination result.

  As described above, according to the present invention, it is easy to change not only the setting parameters in the case of a ticket change, but also the change of hardware and the processing content using the hardware by an instruction from the main control unit. Can be changed. According to this method, the sheet processing apparatus set for the first country can be easily changed for the second country.
