Description

[Detailed Description of the Invention] "Industrial Application Field" This invention provides a method for storing banknotes loaded in a loading section.
The present invention relates to a banknote conveyance device that detects the denomination of the frontmost banknote, confirms and discriminates the denomination and authenticity of the detected banknote while conveying it, and further performs sorting processing based on the determination result.

"Prior Art" As is well known, conventional banknote conveyance devices discriminate banknotes while conveying the banknotes.

For example, the deposit/withdrawal device described in Japanese Patent Application Laid-Open No. 57-147791 has a plurality of discriminating parts in the conveyance path,
These are used to identify the conveyed banknotes.

That is, the deposit system is provided with a discrimination section 23, the circulation system is provided with discrimination sections 62, 63, 64, and the withdrawal system is provided with detection sections 72, 73, and these are used to discriminate the transported banknotes. .

Here, the deposit system discriminating section 23 is constituted by, for example, a magnetic head, and reads the printing pattern of the banknotes to determine authenticity, denomination, and overlap of two bills.

The circulatory system discriminating unit 62 is a length abnormality detector configured with a photoelectric sensor and detects the length of the banknote, and the discriminating unit 63 is a length abnormality detector configured with a cam and a roller.
Two-sheet overlap detector for detecting overlapping sheets, discrimination unit 6
Reference numeral 4 denotes a banknote revalidation detector which is composed of a magnetic head or a photoelectric sensor and is used to determine the denomination of the banknote.

Further, the dispensing system detection units 72 and 73 detect the length of banknotes and the overlap of two banknotes, and are similar to the detection units 62 and 63 described above.

In this manner, the cited document describes a technique for blocking the length of conveyed banknotes, the overlap of two banknotes, and the denomination using a separate discrimination section.

"Problem to be Solved by the Invention" By the way, in the conventional device described above, each discrimination section was provided in series and individually, so
The conveyance speed of banknotes is limited by the length of the conveyed banknotes, the overlap between two banknotes, and the denomination determination which takes the longest processing time among the denomination determinations. For this reason, there have been cases in which banknote discrimination processing has not been able to keep up with the increase in conveyance speed.

For example, when distinguishing between the four types of banknotes currently in use, the characteristic parts of each banknote are extracted and the discrimination is performed, but it is necessary to perform the discrimination process for up to four denominations. There were times when the time could not keep up with the transport speed.

And in order to eliminate this inconvenience,
Multiple identification devices (for example, 4) consisting of CPUs, etc.
In this case, it was necessary to set up a system and perform the discrimination process in parallel. As a result, there is a disadvantage that the transport section has a plurality of configurations and is expensive.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a high-speed and inexpensive bill conveyance device by performing bill discrimination at the loading section and during conveyance.

"Means for Solving the Problems" In order to solve the above problems, the present invention sequentially feeds out the frontmost banknotes from among the mixed denomination banknotes stacked in a banknote loading section and conveys the fed banknotes. The denominations are determined by sequentially transporting the denominations one by one.
In the banknote conveyance device configured to store the banknote in the storage unit, a first detection unit is provided in the banknote loading unit and detects a characteristic part of the frontmost banknote of the loaded banknote while the banknote is stationary; a first control unit that determines the denomination of the frontmost banknote based on the output of the first detection unit and outputs denomination data; A detecting section detects characteristic parts of the delivered banknote in the conveyance state of the banknote, predicts the denomination of the conveyed banknote based on the denomination data from the first control section, and detects a signal from the second detecting section. The present invention is characterized by comprising a second control section that checks the denomination of the conveyed banknote based on the following and performs authenticity determination.

Further, the first detection section is characterized in that it is a detection section that detects the color tone of the entire surface of the banknote.

Further, the present invention sequentially feeds out the frontmost banknotes among the mixed denomination banknotes loaded in a stack in the banknote loading section, and sequentially transports the fed banknotes one by one from the conveying section to determine the denomination. , a first detection unit that is provided in the banknote loading unit and detects a characteristic part of the frontmost banknote of the loaded banknote in a state in which the banknote is stationary; A first control unit that determines the denomination of the frontmost banknote based on the output of the first detection unit and outputs denomination data is provided near the transport unit, and the banknote is transported from the banknote loading unit. a second detection unit that detects a characteristic part of the banknote while the banknote is being conveyed;
A second control that predicts the denomination of the conveyed banknote based on the denomination data from the first control unit, and checks the denomination of the conveyed banknote based on the signal from the second detection unit to determine authenticity. and a sorting section that performs a process of sorting genuine banknotes and counterfeit banknotes in batches by denomination and into predetermined storage boxes constituting the storage section, respectively, based on the denomination and authenticity determination result. Features.

Further, the first detection section is characterized in that it is a detection section that detects the color tone of the entire surface of the banknote. "Operation" The first detection section detects the characteristic portion of the frontmost bill among the bills in the loading section, that is, the bill to be conveyed next. Based on this detection result, the first control section discriminates the denomination, outputs denomination data, and supplies this to the second control section.

On the other hand, the second detection section detects a characteristic part of the banknote conveyed from the loading section, and transmits the result to a second detection section.
Transfer to control unit. The second control section performs only the processing corresponding to the denomination specified by the denomination data, and recognizes the denomination and determines authenticity. For example, when the denomination data indicates a 1,000 yen bill, the second control section only checks the denomination of the 1,000 yen bill and determines its authenticity based on the signal from the second detection section. In this way, the second detection section and the second control section only need to perform discrimination for one denomination. Thereby, it is possible to speed up the banknote discrimination process. Further, since the denomination is checked twice by the first detection section and the first control section, and by the second detection section and the second control section, the reliability of denomination discrimination can be increased.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The bill conveyance device of the present invention is mainly installed inside a bill sorting machine used at the rear of a financial institution such as a bank, that is, in a department that collectively manages cash within a store. The banknote conveyance device determines the denomination and authenticity of each mixed denomination banknote, and, based on the denomination and authenticity determination results, stores genuine banknotes by denomination and counterfeit banknotes all at once into a predetermined storage box. It is designed to be stored separately.

FIG. 1 is a side view showing the mechanical part of a banknote conveying device according to an embodiment of the present invention. In the figure, 1 is a loading part into which a large number of banknotes of mixed denominations are stacked, and 2 is a loading part into which a large number of banknotes of mixed denominations are loaded. This is a conveyance section that sequentially conveys banknotes one by one, which are sequentially fed out from the frontmost banknotes among the mixed denomination banknotes loaded in the loading section 1. The loading section 1 includes a transparent banknote receiving plate 4 that supports banknotes 3 substantially horizontally.
A first detection unit 5 detects the color tone of the entire surface of the banknote 3a that comes into contact with the upper surface of the banknote receiving plate 4 (that is, the banknote to be conveyed next) from below the banknote receiving plate 4.
and is provided.

On the other hand, the conveyance unit 2 includes a second detection unit 6, forks 7a to 7d for distributing bills whose denominations and authenticity have been determined by denomination, and each of the distributing forks 7a.
- Storage box 8a provided corresponding to 7d
~8d are arranged in the shape of the conveyance path 9. Further, a storage box 8e for storing counterfeit banknotes is arranged at the end of the conveyance section 9. Here, the second
The detection unit 6 has an optical sensor that detects the pattern, color tone, etc. of the banknote, and a magnetic sensor that detects the properties of printing ink.

Next, FIG. 2 is a block diagram showing the configuration of the detection system of this embodiment. In the figure, 11 is a first discrimination system, 12 is a second discrimination system, and 13 is a conveyance control system.

First, the first discrimination system 11 includes a first detection section 5 and a first control section 14, and the first control section 14 determines the denomination of the banknote 3a based on the color tone of the banknote 3a detected by the first detection section 5. I'm starting to be able to discern. In this case, the output I/O (input/output port) of the first detection unit 5
15 to the CPU 16 and written to the RAM 17. Then, the denomination is determined based on the program and color tone pattern stored in the ROM 18, and the denomination data is transferred to the second discrimination system 12 via the data bus 19 as denomination data. Note that the components 15 to 18 constitute the first control section 14.

Next, the second discrimination system 12 includes a second detection section 6 and a second control section 20, and checks the denomination and determines authenticity based on the denomination data supplied from the first discrimination system 11. . That is, the second
The detection unit 6 detects the banknotes 3a conveyed from the loading unit 1.
Reads the external shape, magnetic pattern, photo pattern, and color tone pattern of the
Supplied to CPU22. The CPU 22 writes these patterns into the RAM 23, and performs denomination picture recognition and authenticity determination based on the programs stored in the ROM 24 and various patterns. In this case, the denomination of the banknote 3a has already been determined in the first discrimination system 11.
Since the second discriminating system 12 is notified as the metal data, the second discriminating system 12 only needs to perform the discriminating process corresponding to the denomination indicated by the metal data. The final discrimination system result of the banknote 3a is transferred to the conveyance detection system 13 via the data bus 19. Note that the components 21 to 24 constitute the second control section 20.

Next, the conveyance control system 13 includes a conveyance system sensor 25,
Conveyance system drive section 26, distribution drive section 27, table display section 28, and control section 3 that controls each of these sections.
0 and an operation input section 31 for operating the control section 30. Then, when the final discrimination result of the banknote 3a is supplied to the control unit 30 via the data bus 19, the control unit 30 selects one of the distribution forks 7a to 7d corresponding to the denomination of the banknote 3a via the distribution drive unit 27. The banknotes 3a are sorted into predetermined storage boxes 8a to 8e. Note that the control unit 30, like the other control units 14 and 20, has an I/O 32, a CPU 33, a RAM 64, and a ROM 35.
Consisting of Conveyance control system 1 including this control section 30
The structure and operation of the third embodiment are completely the same as those of the conventional one, so a detailed explanation thereof will be omitted.

In such a configuration, the operation of this embodiment will be described using an example in which the next banknote 3a to be fed out from the loading section 1 is a 1,000 yen banknote.

First, in the first discrimination system 11, the denomination of the banknote 3a is discriminated while it is still loaded in the loading section 1. That is, the first detection unit 5 reads the color tone of the banknote 3a over the entire surface of the banknote, converts this into an electrical signal, and supplies the electrical signal to the CPU 16 via the I/O 15. After writing this signal into the RAM 17, the CPU 16 compares it with the color tone pattern stored in the ROM 18, determines that the denomination of the banknote 3a is "1,000 yen," and transfers it to the second discrimination system 12 as denomination data. do.

In the second discrimination system 12, the CPU 22 recognizes that the denomination of the banknote 3a to be sent this time is a thousand yen bill based on the denomination data, and the second detection unit 6
Characteristic parts of the 1,000 yen bill are extracted from the banknote 3a being conveyed through the banknote 3a. After writing the extracted data into the RAM 23, it is compared with various patterns for 1,000 yen bills stored in the ROM 24 to determine whether the banknote 3a is a genuine 1,000 yen bill. Then, the determination result is transferred to the conveyance control system 13.

In this way, the second discrimination system 12 only needs to know the denomination of the banknote 3a (in this case, a 1,000 yen bill) in advance and then check it, so it can check the denomination of the banknote 3a many times as in the past (for Japanese banknotes). This eliminates the need for discrimination processing (up to four times in most cases), significantly shortening processing time.

The banknotes 3a whose denominations have been determined in this manner are distributed to a storage box 8a for 1,000 yen banknotes, for example, by a distribution fork 7a.

Next, FIG. 3 shows a modification 40 of the loading section 1 of the present invention.
FIG. In the figure, the banknotes 3 are stored in an upright position on a banknote receiving plate 41, and are pressed from behind by a movable holding plate 42. The color tone of the entire surface of the banknote 3a is detected by the first detection unit 5 provided in front of the frontmost banknote 3a.

In the above-described embodiment, the denomination in the loading section 1 is determined based on the color tone, but it is also possible to determine the denomination based on other characteristics such as shape, magnetic pattern, etc. It is.

"Effects of the Invention" As explained above, the present invention sequentially feeds out the frontmost banknotes among the mixed metal banknotes loaded in a stack in the banknote loading unit, and sequentially transports the fed banknotes one by one by the conveyance unit. In the banknote transport device, the banknote carrying unit is provided in the banknote loading unit to identify the denomination of the banknote and store the banknote in the storage unit. a first detecting section for detecting a first detecting section; a first controlling section for determining the denomination of the frontmost bill based on the output of the first detecting section and outputting denomination data; and a first controlling section provided in the vicinity of the conveying section. , a second detection unit that detects a characteristic part of the banknote conveyed from the banknote loading unit in the conveyance state of the banknote, and predicting the denomination of the conveyed banknote based on the denomination data from the first control unit; and a second control section that checks the denomination of the conveyed banknote based on the signal from the second detection section and determines authenticity; is,
a first detection unit that detects a characteristic part of the frontmost banknote of the loaded banknotes while the banknote is stationary; and a denomination of the frontmost banknote is determined based on the output of the first detection unit. a first control section that outputs denomination data using the banknote, and a second detection section that is provided near the conveyance section and detects a characteristic part of the banknote conveyed from the banknote loading section in the conveyance state of the banknote. , a second device that predicts the denomination of the transported banknote based on the denomination data from the first control unit, and checks the denomination of the transported banknote based on the signal from the second detection unit to determine authenticity. A configuration comprising: a control unit; and a sorting unit that performs a process of sorting genuine banknotes by denomination and fake banknotes in batches into predetermined storage boxes constituting the storage unit, based on the denomination and the authenticity determination result. So,
The following effects can be achieved.

Since the second detection section and the second control section perform denomination discrimination based on the discrimination results of the first detection section and the first control section, it is only necessary to perform one type of denomination discrimination. Speed can be achieved.

Since the discrimination result obtained by the first detection section and the first control section is confirmed by the second detection section and the second control, the denomination is checked twice, and the denomination can be determined reliably. .

The first detection section and the first control section are configured to carry the same length as when one detection section and one control section are provided in order to determine the denomination of stationary banknotes loaded in the bill loading section. You can do it on the road. That is, even though the detection section and the control section are provided in two systems, there is no need to increase the size of the bill conveyance device, so the bill conveyance device can be installed in a store of a financial institution such as a bank. It is suitable for being incorporated into a banknote sorting machine.

Since the first discrimination system detects stationary banknotes loaded in the loading section, stable detection data can be obtained and the reliability of denomination discrimination can be improved.

For example, if the banknotes are transported at a rate of 10 per second and separated by a distance equal to the length of the banknotes, then
Feeding from the loading section is done every 100msec,
The fed banknotes pass one point on the conveyance path in 50 msec. Therefore, detecting a banknote at the loading section can take a longer detection time than detecting a banknote midway through the transport section, and stable detection is possible. This effect becomes more pronounced as the banknote transport speed increases.
