Description

  The present invention relates to a processing apparatus for paper sheets such as securities, and more particularly to a paper sheet processing apparatus that performs transport monitoring with a plurality of CPUs (Central Processing Units) when a transport path is long.

  A paper sheet processing apparatus for processing paper sheets such as securities takes out paper sheets one by one from a bundle of paper sheets (for example, 1000 sheets) that are input in a batch according to the processing unit. The paper sheet discriminating device discriminates the quality (shape, damage, etc.) of the paper sheet, and a normal ticket (hereinafter referred to as a regular ticket) or a defective ticket (hereinafter referred to as a non-performing ticket). When the number of stacked sheets reaches a predetermined number (for example, 100), it is bundled with a binding band such as banknotes to form a handle. It is a device to do.

  In the paper sheet processing apparatus, a paper sheet to be transported is jammed in the middle of transportation (hereinafter referred to as a ticket jam), or a paper sheet is missing due to dropping or tearing from the transportation path in the middle. May occur (hereinafter referred to as ticket loss).

  The above-mentioned method for monitoring the jam is arranged by arranging a plurality of conveyance monitoring sensors along the conveyance path along which the paper sheets (tickets) are conveyed, and between the two points where the conveyance monitoring sensors are arranged. A method of measuring the arrival time and confirming that the measurement result falls within the specified time is performed. As a result of the confirmation, if the passage of the ticket cannot be confirmed even after the lapse of the specified time, it is determined that the ticket is jammed and the paper sheet processing apparatus (apparatus) is stopped.

  In addition, as a method for monitoring the absence of a ticket, a method is used in which the length of the ticket is measured by each conveyance monitoring sensor and it is confirmed that the value falls within a specified value. As a result of the confirmation, if the length is shorter than the specified length, it is determined that the ticket is missing during transportation, and the apparatus is stopped in the same manner as the above-described ticket jamming.

Immediateness is required for the ticket arrival time monitoring and the ticket length confirmation by each conveyance monitoring sensor, and therefore the CPU for performing the confirmation is usually controlled by one. This is because if there is no responsiveness, it takes a long time from the occurrence of the ticket jamming to the confirmation, and there is a possibility that a serious trouble is induced. A method of arranging a plurality of conveyance sensors on a conveyance path and monitoring the passage is known (for example, see Patent Document 1).
JP-A-9-165123 (Page 3-4, FIG. 2)

  However, with regard to the conveyance monitoring such as ticket jamming or ticket missing by the conventional conveyance monitoring sensor, the conveyance path becomes longer as the apparatus becomes large, and it becomes impossible to monitor all the ticket conveyance on the conveyance path with one CPU. Come. Conventionally, therefore, the conveyance path length that can be conveyed and monitored by one CPU has been experimentally confirmed to be equivalent to the length of 32 tickets when the conveyance speed is 5 m / s, for example.

  Therefore, there is a method of monitoring the conveyance with a plurality of CPUs when the apparatus becomes large and the conveyance path becomes long. There was a problem. If the pass of the ticket cannot be monitored by the transport monitoring sensor, it is conceivable to exchange the ticket movement information between the CPUs to replace the monitoring, but the problem that the immediacy cannot be maintained is not solved.

  Furthermore, since the ticket information from each transport monitoring sensor is not transmitted between CPUs when transporting a ticket across CPUs, the ticket length confirmation is interrupted when the monitoring CPU changes, resulting in insufficient ticket transport during transport. There was a problem.

  The present invention has been made in order to solve the above-described problems.

  Next, the conveyance monitoring of the paper sheet P by the conveyance monitoring sensor of the present embodiment will be described.

  When a bundle of 1000 sheets Ps is collectively supplied to the backup plate 1A of the supply unit 1 and extraction is started, the backup plate 1A is raised and the sheet P is conveyed one by one from the extraction rotor 2 to the transport path 3. To be taken out. The taken paper sheet P is conveyed by the above-described method and detected by the detection device 6. The processing until the bundle is formed by the classification and collection based on the detection result by the detection device 6 is as described above. An example of the conveyance monitoring process of the paper sheet processing apparatus 100 configured as described above will be described with reference to FIGS. 3 and 4 shown below.

  FIG. 3 is a flowchart for explaining the conveyance monitoring process of the module M1 constituting the paper sheet processing apparatus 100. When the paper sheet P is taken out by the take-out rotor 2, it is detected by a conveyance monitoring sensor (hereinafter referred to as a sensor) PC11 (S1). The detected paper sheet P is detected by the detection device 6, and the arrival times T11 and 12 from the sensor PC11 to the sensor PC12 are monitored (S2). This arrival time means a passage time during which the paper sheet P is conveyed and passes between the sensor PC11 and the sensor PC12.

  Therefore, the passage time measuring means for the arrival times T11 and 12 counts the time from when the sensor PC11 becomes dark until the sensor PC12 becomes dark every predetermined time (for example, 200 μs). This count can be measured using a timer interrupt of the M1 control CPU that manages the module M1. Alternatively, it can be measured by a hardware timer (not shown) provided outside managed by the M1 control CPU.

  The passage time measured by the passage time measuring means described above is judged whether the passage time is good or bad by the comparison / determination means shown in the following equation (1). If the result of the determination of the following expression (1) is within the specified value, it is determined to be normal (Yes in S4).

(T11 · 12−ΔT) ≦ T11 · 12 ≧ (T11 · 12 + ΔT) (1)
T11 · 12: Arrival time ΔT between sensor PC11 and sensor PC12: allowable value On the other hand, when arrival time T11 · 12 exceeds the specified value shown in the above equation (1) (No in S3), it is determined that the ticket is jammed. (S14).

  In step S4, when the paper sheet P is detected by the sensor PC 12 (Yes in S4), the arrival time T12 · 13 until the sensor PC 12 reaches the sensor PC 13 is monitored (S5). This arrival time T12 · 13 is confirmed in the same manner as the above equation (1), and if it is within the specified value, it is determined to be normal (Yes in S7).

  On the other hand, when the arrival times T12 and 13 are confirmed in the same manner as in the above equation (1) and exceed the specified value (No in S6), it is determined that the ticket is jammed (S14).

  Similarly, when the arrival time T13 · 14 (S8) until reaching the sensor PC 14 from the sensor PC 13 and the result of determination by the detection device 6 for the paper sheet P is a rejection ticket, the arrival time from the sensor PC 13 to the sensor PC 15 (S11) is also monitored.

  If the result of the confirmation is within the specified value as described above, it is determined to be normal (Yes in S9 or Yes in S12), and if it exceeds the specified value, it is determined that the ticket is jammed (No in S9 or S12). No).

  The paper sheet P is discriminated as a correct ticket, a damaged ticket, or an excluded ticket based on the result of detection by the detection device 6. Based on the determination result, the accumulation location of the paper sheet P is set. Receiving this setting information, the M1 control CPU 10 switches the sorting gate G11 based on the determination result. Accordingly, the sorting gate G11 is switched so that the paper sheet P determined to be a correct ticket or a damaged ticket is conveyed to the module M2 or the module M3 side. On the other hand, when it is determined that the ticket is a rejection ticket, the sorting gate G11 is switched so as to be transported to the rejection ticket stacking device 16 provided in the module M1.

  FIG. 4 is a flowchart for explaining the conveyance monitoring process of the module M2 constituting the paper sheet processing apparatus 100. In this embodiment, the M1 control CPU 10 of the module M1 and the control CPU 20 of the module M2 are connected by the LAN 50, and the accumulated location information based on the detection result of the detection device 6 in the module M1 and the PC 14 ticket length information by the sensor PC 14 are M1. The control CPU 10 notifies the M2 control CPU 20 of the module M2 through the LAN 50 (S20). Based on this information, the conveyance monitoring process by a plurality of CPUs will be described.

  The paper sheet P conveyed to the module M2 is detected by the sensor PC 21 (S21).

  The M2 control CPU 20 rotates the sorting gate G <b> 21 based on the accumulation location information received from the M <b> 1 control CPU 10 and conveys the paper sheet P to the accumulation / sealing device 21. Further, in response to the fact that the PC 21 is dark, the ticket length measurement by the PC 21 is started. Specifically, the time during which the PC 21 is dark is counted with a predetermined clock (for example, a clock having a cycle of 200 μs) (S22).

  In addition, the arrival times T21 and T22 from the sensor PC21 to the sensor PC22 are monitored (S24). As a result of this monitoring, the arrival times T21 and 22 are confirmed in the same manner as in the above equation (1), and are determined to be normal if they are within the specified values (Yes in S25).

  On the other hand, when the arrival times T21 and 22 exceed the specified value (No in S25), it is determined that the ticket is jammed (S26).

  In step S23, when the brightness of the sensor PC21 is detected (No in S23), the bill length measurement by the sensor PC21 is stopped, and the bill length by the sensor PC21 is determined from the time when the paper sheet P passes the sensor PC21. It is measured (S28). Whether or not the ticket length measured in this way and the ticket length notified from the M1 control CPU 10 are the same length is judged (S29).

  At this time, the bill length by the PC 14 which is the most downstream conveyance monitoring sensor of the conveyance monitoring sensor in the module M1 immediately upstream of conveyance is used. This is because, if the length measurement result by the conveyance monitoring sensor in the vicinity of the junction point of different modules is the same, it becomes a condition for allowing the conveyance path to be regarded as continuous. That is, the ticket length information transmitted from the M1 control CPU 10 which is the CPU arranged in the module located upstream is compared with the ticket length information by the ticket length measuring means in the module M2, and the comparison determination result is obtained. Based on this, the lack of the ticket is determined. Therefore, in this embodiment, the ticket lengths of the sensor PC 14 and the sensor PC 21 arranged in the vicinity of the junction point between the module M1 and the module M2 are compared and determined (S29).

  When determining the ticket length, if the ticket length by the sensor PC 14 is shorter than the ticket length by the sensor PC 21 as a result of this comparison determination, it is determined that the ticket is missing (S30).

  As described above, according to the embodiment of the present invention, even when the apparatus is enlarged and the conveyance path becomes long, the module is divided within a range in which conveyance can be monitored by one CPU, and each module is connected to the LAN. A plurality of modules by measuring the length of the paper sheet P transported by the module located at the upper level of transport and transmitting the ticket length data of the paper sheet P to the next module as the ticket length information. Even when the paper sheet P is transported between them, the transport monitoring of the paper sheet P can be performed by a plurality of CPUs.

  The above embodiment is a case of one type of paper sheet P. However, in the case of two or more types of paper sheets P, the module M2 is added between the modules M1 and M3. Even when M2 is added, since the CPU is mounted on each module, the ticket conveyance monitoring capability on the conveyance path is equivalent to the case where the module M2 is not added.

  FIG. 5 is a control block diagram of the multiple sheet processing apparatus 100 according to the second embodiment of the present invention.

  The configuration of each module of the present embodiment is the same as that of the first embodiment shown in FIG. 2, but the output of the conveyance monitoring sensor PC14 arranged at the most downstream in the conveyance direction of the module M1 is connected to the M2 control CPU 20 of the module M2. It becomes the composition. Since the other parts are the same as those in the first embodiment, the description of the same parts will be omitted and the different parts will be described.

  As a result, the M2 control CPU 20 can access the sensor PC 14 of the module M1, which is a transport upstream module. As a result, it is possible to monitor the arrival times T14 and 21 from the sensor PC14 of the module M1 to the sensor PC21 of the module M2, and it is possible to detect a paper jam occurring between the sensor PC14 and the sensor PC21 as described above. Also, since the accumulated location information on the paper sheet P and the ticket length information of the paper sheet P are transmitted from the module M1 through the LAN 50, the same as when the module M1 and the module M2 are connected in series. An effect is obtained.

  Further, the same effect as described above is such that the output of the conveyance monitoring sensor PC25 arranged at the most downstream in the conveyance direction of the module M2 is connected to the M3 control CPU 30 of the module M3. As a result, the M3 control CPU 30 can access the sensor PC 25 of the module M2, which is a transport upstream module module. As a result, it is possible to monitor the arrival time T25 · 31 until the sensor PC25 of the module M2 reaches the sensor PC31 of the module M3, and it is possible to detect the jammed ticket generated between the sensor PC25 and the sensor PCPC31 as described above. Further, since the stacking location information regarding the paper sheet P and the ticket length information of the paper sheet P are transmitted from the module M1 through the LAN 50, the effect is obtained as if the module M2 and the module M3 are connected in series. can get.

  As a result, since the continuity between the module M1 and the module M2 and the continuity between the module M2 and the module M3 are secured, the module M1 to the module M3 are continuously connected to form a conveyance path. Similar effects can be obtained.

  As described above, according to the embodiment of the present invention, the same effect as in Embodiment 1 can be obtained. In other words, even when the apparatus is large and the conveyance path is long, the CPU and the module immediately upstream can monitor the conveyance of the module and the modules in the immediate upstream, thereby conveying the paper between the modules. Even so, it becomes possible to monitor conveyance of the paper sheet by a plurality of CPUs. In this embodiment, the interval between the sensor PC 14 of the module M1 and the sensor PC 21 of the module M2 is short, and it is difficult to receive the conveyance monitoring data of the module M1 via the LAN, and the M2 control CPU 20 of the module M2 Since the most recent upstream conveyance monitoring sensor can be accessed through the line 51, continuous conveyance monitoring becomes possible.

  Moreover, although the said Example is a case of 1 type of paper sheets, in the case of 2 or more types of paper sheets, it is set as the structure which adds the module M2 between the module M1 and the module M3. Even when M2 is added, since the CPU is mounted on each module, the ticket conveyance monitoring capability on the conveyance path is equivalent to the case where the module M2 is not added.

  Furthermore, as an effect peculiar to the present embodiment, since it becomes possible to monitor the conveyance between the last sensor of the conveyance upstream module and the first sensor of the downstream module, it is as if a plurality of CPUs are used. The same effect as that when the conveyance is monitored by the CPU can be obtained.
