Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a control block diagram of the banknote sorting device, and fig. 2 is a schematic configuration diagram of the banknote sorting device. The bill sorting device is a device for performing billing services such as counting, authenticity determination, and perfect defect separation processing on the collected bills S.

As shown in fig. 1, the banknote sorting device 200 includes a control unit 250 that controls each unit in the device, a ROM251 that stores an operation program and the like of the control unit 250, a RAM252 that stores control data of each unit controlled by the control unit 250 in a readable and writable manner, a display operation unit 253 that receives an input from an operator and displays the input or processed data, a communication unit 254 that transmits and receives information when connected to a host computer, and a storage unit 255 that stores various information. Here, the control unit 250 is a processor that executes an operation program, and controls each unit by executing the operation program. The storage unit 255 stores authenticity judgment reference information 256 used for authenticity judgment of a banknote, good defect separation reference information 257 as a reference for good-note defective note judgment, and banknote image information 258 as image information acquired by the scanner a204 and the scanner B206.

Further, the banknote sorting apparatus includes a crown-letter number reading sensor 201 as a recognition mechanism for the unique feature amount of the banknote, a number-of-banknotes detecting sensor 203 for detecting the number of banknotes, a scanner a204 for acquiring images of all the front and back sides of the banknote, a defective-banknote detecting sensor 205 for reading the level of a defective banknote of the transported banknote, a scanner B206 for acquiring a transmission image of the entire banknote, and a distribution gate 230 for distributing the banknote checked by the recognition unit.

Further, display units 246A to 246D are provided corresponding to the respective stacking units 245A to 245C and reject stacking unit 240 (in the following description, the stacking units 245A to 245C may be collectively referred to as "stacking unit 245", and the display units 246A to 246D may be collectively referred to as "display unit 246"). The display unit 246 is, for example, a liquid crystal display, and functions as a display means for displaying the number of banknotes stacked in each stacking unit and notifying the stackers of the stacking unit from which the banknotes should be removed.

Next, a mechanical structure of the banknote sorting device 200 will be described with reference to fig. 2. The banknote sorting device 200 includes a recognition unit 210, a hopper (hopper)220, a distribution gate 230, a reject stacking unit 240, a 1 st stacking unit 245A, a2 nd stacking unit 245B, a 3 rd stacking unit 245C, and a transport path connecting these units. Display portions 246A to 246D are provided on the front surfaces of the stacking portions 245 and 240, respectively. Optical sensors 247A to 247D are provided at the rear end bottom portions of the stacking units 245 and 240, respectively, and the presence or absence of bills stacked in the stacking units is detected by these optical sensors. Although not shown, an optical sensor is provided at the bill feed-out port of the insertion box 220 to detect the presence or absence of bills in the insertion box 220.

The input box 220 is an input unit for banknotes S, and the banknotes S loaded into the input box 220 by the operator are fed out one by rotation of the rollers. The recognition unit 210 is positioned on the conveyance path of the banknotes, and includes a crown-type-number reading sensor 201, a number-of-sheets detection sensor 203, a scanner a204, a defective-note detection sensor 205, and a scanner B206. The following processing (account tie processing) was performed: the number of banknotes S fed from the insertion box 220 is counted, and the authenticity of the banknotes is determined, and the perfect defect separation is performed based on the result of the authenticity determination. The dispensing door 230 dispenses the banknotes S tallied by the recognition unit 210 according to the result of the tallying. The reject stacking unit 240 and the stacking units 245A to 245B are portions (storage units) for storing the banknotes to be dispensed. Each stacking unit has an opening on the front surface of the apparatus (the side surface on which the inlet box 220 is provided) so that the worker can easily take out the banknotes.

Various settings can be made as to which stacking portion the banknote classification result is assigned. In the following description, good tickets are assigned to the 1 st stacking unit 245A and the 2 nd stacking unit 245B, defective tickets are assigned to the 3 rd stacking unit 245C, and abnormal transportation tickets or counterfeit tickets (referred to as reject tickets) are assigned to the reject stacking unit 240. The reject stacker display portion 246D and the 1 st to 3 rd stacker display portions 246A to 246C display the number of banknotes stored in each stacker in response to an instruction from the control portion 250. The display operation unit 253 also displays the number of banknotes stacked in the reject stacking unit 240 and the 1 st to 3 rd stacking units 245A to 245C. Before the banknotes are inserted into the insertion box 220, the display unit 246 and the display operation unit 253 display "0".

As a feature of the present embodiment, the control unit 250 determines the stacking unit from which the banknotes should be removed, and changes the display of the display unit corresponding to the stacking unit.

< example 1>

Next, the banknote sorting process operation will be described with reference to fig. 3. This operation is mainly performed by the control of the control unit 250.

The banknotes S loaded in the input box 220 are separated one by the rotation of the rollers, and are fed out from the input box 220 and conveyed to the recognition unit 210 (S101). The recognition unit 210 counts the number of banknotes by the number-of-banknotes detection sensor 203 (S102), acquires a serial number by the serial number reading sensor (S103), and scans the reflection image and the transmission image of the front and back surfaces of the banknote S by the scanner a204 and the scanner B206 to acquire a banknote image (S104). The acquired banknote image and the serial number of the banknote are stored in the storage unit 255 (S105). Then, the banknote image and the serial number are compared with the authentication criterion information 256, and the banknote recognition process is performed (S106).

When the banknote is a transport-abnormal banknote as a result of the banknote recognition processing (yes in S107) and the banknote is not a genuine banknote (i.e., a counterfeit banknote) (no in S109), the banknote S is transported to the reject stacking unit 240 by driving the distribution gate 230 and is collected in the reject stacking unit 240 (S108). When the abnormal bill is not transported (no in S107) and the bill S is a genuine bill (yes in S109), the defective bill level of the bill is read by the defective bill detection sensor 205 (S110), and it is determined whether or not the bill S is a genuine bill (S111). If the banknote S is not a good banknote (i.e., if it is a defective banknote) as a result of the determination (S111: no), the banknote S is transported to the 3 rd stacking unit 245C by driving the distribution gate 230 and is collected in the 3 rd stacking unit 245C (S115).

If the result of the determination (S111) is that a good note is present, the banknotes S are stacked in the 1 st stacking unit 245A or the 2 nd stacking unit 245B. The control unit 250 manages the number of good tickets and controls to switch the stacking unit as the stacking destination of banknotes according to whether or not the number of good tickets exceeds 100, for example. 100 sheets are the upper limit number of banknotes stacked in the 1 st stacking unit and the 2 nd stacking unit. That is, when the number of good notes does not exceed 100 (S112: NO), the banknotes S are transported to the 1 st stacking unit 245A and stacked in the 1 st stacking unit 245A (S113). When the number of good notes exceeds 100 (S112: YES), the banknotes S are transported to the 2 nd stacking unit 245B and stacked in the 2 nd stacking unit 245B (S114). These operations are repeated until there are no more banknotes loaded in the insertion box 220 (S117).

In the present embodiment, when the number of banknotes stacked in any one of the plurality of stacking units reaches the upper limit (for example, the full state of the stacking unit), the change of the display of the corresponding display unit 246 notifies the worker of which stacking unit the banknotes in the stacking unit should be removed. Next, the determination of the stacking unit from which the banknotes should be removed and the control of the display change of the corresponding display unit (S116) will be described.

The control unit 250 updates the respective numbers of the good ticket, the defective ticket, and the rejected ticket determined by the recognition unit 210, and stores and manages the same in, for example, the RAM 252. The control unit 250 displays the number of banknotes stacked in the stacking unit on the display unit 246 provided in each of the stacking units 245 and 240. Further, the control unit 250 changes the display state of the display unit 246A of the 1 st stacked unit 245A in the full state. This can notify the worker of the full state, and prompt the removal of the banknotes stacked in the 1 st stacking unit 245A. The control of the change of the display state is, for example, to turn on the display of the number of sheets when the number of sheets does not reach the upper limit of 100 sheets, and to blink the display of the number of sheets when the number of sheets reaches the upper limit.

The notification of the full state to the operator is an alarm notification, and in addition to the blinking display described above, there are various schemes such as changing the display color of the number of sheets from a normal color (for example, blue) to red, or changing the blinking speed. Further, the control unit 250 can prompt the removal of the banknotes from the stacking unit by displaying the number of stacked banknotes for each stacking unit on the display operation unit 253 in accordance with the stacking state of the banknotes in each stacking unit, and changing the display of the number of stacking units that are in the full state to the blinking display.

If the number of stacked banknotes in the 2 nd stacking unit 245B reaches the upper limit in a state where the banknotes stacked in the 1 st stacking unit 245A are not cleared, there is no stacking unit of the stacking destination of the good banknotes. Therefore, the control unit 250 stops the conveyance of the banknotes from the input cassette 220 and causes the number of the display units 246B of the 2 nd stacking unit 245B to blink. If the worker removes 100 banknotes stacked in either the 1 st stacker 245A or the 2 nd stacker 245B, the corresponding

sensor

247A or 247B detects no banknotes. At this time, the controller 250 resumes the conveyance of the banknotes from the insertion box 220 in a state where the destination of the good banknotes is secured. Then, the control unit 250 changes the display of the

display unit

246A or 246B of the stacking unit from blinking to lighting.

Further, the control unit 250 also controls the display of the display units 246C and 246D when the number of banknotes stacked in the 3 rd stacking unit 245C and the reject stacking unit 240 reaches the upper limit, and the display of the display units when the banknotes are removed from the stacking unit reaching the upper limit, as described above.

Here, a case will be described where the number of banknotes stacked in the 1 st stacking unit 245A reaches the upper limit, but the number of banknotes in the other stacking units does not reach the upper limit. The display of the display portion 246A of the 1 st stacked portion 245A blinks. At this time, when the number of banknotes stacked in the 3 rd stacking unit 245C reaches the upper limit, the destination to which the defective banknotes are stacked is no longer present, and therefore the control unit 250 stops the conveyance of the banknotes from the drop box 220. At this time, even if the banknotes stacked in the 1 st stacking unit 245A are cleared, since the stacking destination of the defective banknotes is still not present, the conveyance of the banknotes from the input box 220 is stopped. In contrast, if the banknotes stacked in the 3 rd stacking unit 245C are cleared, the controller 250 resumes the conveyance of the banknotes from the drop box 220 since the destination of the defective banknotes is secured. In such a state, the control unit 250 changes the display of the display unit 246C of the 3 rd stacking unit 245C so that the banknotes are preferentially removed from the 3 rd stacking unit 245C. For example, the control unit 250 temporarily turns on the display unit 246A of the 1 st stacking unit 245A in the full state of banknotes, and turns on the display unit 246C of the 3 rd stacking unit 245C in the full state. Then, if it is detected that the banknote is cleared from the 3 rd stacking unit 245C (i.e., if the sensor 247C detects no banknote), the control unit 250 releases the blinking state of the display unit 246C, changes the display of the display unit 246A from the lit state to the blinking state, and prompts removal of the banknote from the stacking unit 245A.

< example 2>

An example of determination of the stacking unit to remove the banknotes stacked in the stacking unit will be described with reference to fig. 4. In this example, the control unit 250 determines the priority of the stacking unit from which the banknotes should be removed, according to a preset policy. That is, a table for managing a policy for determining the stacking unit from which the banknotes should be removed is stored in advance in the storage unit 255 or the RAM252, and the control unit 250 manages the number of banknotes stacked in each stacking unit 245 and 240, determines whether or not the number of banknotes in each stacking unit is equal to or greater than the upper limit of 100 (full state), and determines the 1 st priority stacking unit and the 2 nd priority stacking unit from which the banknotes should be removed according to the determination result. The configuration of fig. 1 to 3 is the same as that of example 1.

For example, as in the example of No1, when the 1 st, 3 rd and reject stacks are in the full state and the 2 nd stack is not in the full state, the control unit 250 performs alarm display (e.g., blinking display) on the display units 246C and 246D of the 3 rd and reject stacks as the 1 st priority clear stack. Then, an alarm display is performed on the display portion 246A of the 1 st stack portion as the 2 nd priority stack portion. This is because the 2 nd stacker for good tickets is not yet full, and thus there is a margin, and it is necessary to remove the banknotes in the 3 rd stacker and reject stacker with the highest priority.

Further, as in the example of No8, when the 1 st, 2 nd and 3 rd stacking units are in the full state and the reject stacking unit is not in the full state, the control unit 250 displays an alarm on the display unit 246C of the 3 rd stacking unit as the 1 st priority clear stacking unit. Then, an alarm display is performed on the display portion 246A of the 1 st stack portion as the 2 nd priority stack portion. This is because even if the banknotes are removed from the 2 stacking units for the full-loaded good tickets, since only the 3 rd stacking unit for the 1 defective tickets is a bottleneck, the banknotes are removed from the 3 rd stacking unit in the full-loaded state with priority given to the 1 st stacking unit.

< example 3>

An example of the determination of the stacking unit for stacking banknotes on the stacking unit and clearing the banknotes stacked on the stacking unit will be described with reference to fig. 5 and 6. The configuration of fig. 1 to 3 is the same as that of example 1.

In this example, control is performed to collect banknotes in the most suitable stacking unit while monitoring the full state of each stacking unit for each banknote recognized by the recognition unit 210 (see fig. 5), and when a banknote is taken out from a certain stacking unit, control is dynamically changed in the order of priority of the stacking unit and the associated stacking unit (fig. 6). This control is performed by the control unit 250 executing a program.

Referring to fig. 5, the banknotes S loaded in the insertion box 220 are separated one by the rotation of the rollers, fed out from the insertion box 220 and conveyed to the recognition unit 210, and the recognition processing of the banknotes is performed by the recognition unit 210 (S501, S502). The recognized banknotes are transported to the Nth stacking unit according to the recognition result and stacked (S503). The nth stacking unit is any one of the 1 st to 3 rd stacking units and the reject stacking unit described above. Then, it is determined whether or not the nth stacking portion is in a full state (S504). If the bill is judged to be in the full state, the bill is stopped from being fed from the hopper 220, and the process is terminated.

If the result of the above determination is not the full state, the priority order a is set to "1" (S505), and the following processing is performed. That is, whether or not there is a stacked portion in a full state is determined in the order of priority "1" (S506). Here, the distinction refers to the distinction between a good ticket, a defective ticket, and a rejected ticket. In this example, 1 stack portion is assigned to 1 division for a defective ticket and a rejected ticket, and 2 stack portions are assigned to 1 division for a good ticket.

If the determination result in S506 is that there is a stacked portion in the full state, it is determined whether or not the sorted remaining capacity of the nth stacked portion is smaller than the sorted remaining capacity of the priority order a (═ 1) (S507). If the result of this determination is low (yes in S507), the order of priority of sorting of the nth stacking unit is set to a (1), and the following is shifted backward (S511). On the other hand, if the result of the determination is not small (no in S507), it is determined whether the number of divided stacking units of the nth stacking unit is smaller than the number of divided stacking units of the priority order a (1) (S508). If the result is not small, the priority order is (a +1) unless the comparison with all the divisions is completed (S509: NO), and the above-described operations S506 to S509 are repeated (S521).

Thus, the above operation is performed until the nth stacking portion corresponding to the discrimination result of the banknotes becomes the full state.

Next, with reference to fig. 6, control of changing the priority order of a certain stacking unit (nth stacking unit) when banknotes are taken out of the stacking unit will be described.

When the removal of banknotes from the nth stacking unit is detected (S601), the control unit 250 determines whether or not there is a full stacking unit among the N-th stacking units (S602). If the determination result shows that there is no fully loaded stack, the priority of the nth stack is set to the lowest, and the priority order of the other stacks is advanced (S611), and the process ends.

On the other hand, if the determination result in S602 indicates that there is a full stack, the priority order a is set to "1" (S602), and the following processing is performed. That is, whether or not there is a stacked portion in a full state is determined in the order of priority "1" (S604). If the determination result shows that there is no stacking unit in the full state, the order of priority of sorting of the nth stacking unit is set to a (1), and the process is shifted backward (S612), and the process is terminated.

If the determination result in S604 is that there is a stacked part in the full state, it is determined whether or not the sorted remaining capacity of the nth stacked part is smaller than the sorted remaining capacity of the priority order a (═ 1) (S605). If the result of this determination is low (yes in S605), the order of priority of sorting of the nth stacking unit is set to a (1), and the following is shifted backward (S612), and the process ends. On the other hand, if the result of the determination in S605 is not small (S605: no), it is determined whether the number of divided stacking units of the nth stacking unit is smaller than the number of divided stacking units of the priority order a (1) (S606). If the result is not small, the priority order is (a +1) (S621) unless comparison with all the divisions is completed (S607: NO), and the above-described operations S604 to S607 are repeated.

As described above, according to the present embodiment, since the stacking unit from which the accumulated banknotes should be removed can be presented efficiently, the handling ability of the banknotes by the operator is improved. That is, since the conventional work in which the worker determines which of the stacking units should be cleared is not performed, the load on the worker is reduced, and the work can be efficiently performed. In particular, when there are a plurality of stacking units belonging to the stacking destinations of 1 divided bill as in the 1 st stacking unit and the 2 nd stacking unit for stacking good bills, it is effective to determine the stacking unit from which bills should be removed in a predetermined order of priority.

The present invention is not limited to the above-described embodiments, and can be implemented by being variously modified. For example, in the above-described embodiment, 2 stacked parts are assumed for stacking 1 divided good tickets, but a case where 3 or more stacked parts are present in 1 divided good tickets can also be dealt with. Further, it is also possible to deal with a case where there are a plurality of stacking sections for good tickets, defective tickets, and rejected tickets. The present invention is applicable not only to 3 kinds of paper sheets such as a good ticket, a defective ticket, and a reject ticket, but also to a case where 4 or more kinds of paper sheets are stacked in a plurality of 4 or more divided stacking portions.

As another example, in the above-described embodiment, as a means (alarm means) for notifying the stacking unit from which the banknotes should be removed, an example is described in which the display indicating the state of the stacking unit is changed on the display unit 246 or the display operation unit 253. Alternatively, for example, the control unit 250 may be controlled to emit a "bill clearing" sound from a speaker connected thereto. As still another alternative, openable and closable doors may be provided on the banknote-removing side (left end in fig. 2) of each stacking unit 245, and the operator may be notified by opening the door of the stacking unit in which the number of banknotes reaches the upper limit (i.e., by a mechanical change) under the control of the control unit 250.
