Description

Banknote processing apparatus which changes bill processing speed {BANKNOTE PROCESSING APPARATUS OF CHANGING BANKNOTE TRANSFER RATE}

The present invention relates to a bill processing apparatus for varying a bill processing speed, and more particularly, to a bill processing apparatus for varying a bill processing speed with respect to bills initially charged in a predetermined bill processing mode.

Banks, banks, post offices, financial institutions (CITs), currency exchanges, casinos, entertainment facilities, game halls, large distribution stores, airports, ports, duty-free shops, etc. When trading or exchanging bills, such as bills, customers receive bills or pay bills to customers. At this time, the employee who receives or pays the bills may count the bills by hand, but it may take a long time to count the bills, and there may be a counting error during counting, and the counterfeit or damaged bills may need to be sorted out. Generally, banknotes are recognized at the processing speed of hundreds of sheets per minute, automatically calculating the number and amount of each bill, as well as the total amount, classifying forged bills and damaged bills and identifying serial numbers printed on the bills. Banknote processing apparatuses that can be used are commercially available.

In recent years, as the scale of the money economy grows and the barriers between nations become smaller, soaring human and economic exchanges, these bill handling devices can discriminate not only the bills of the country but also various foreign bills within a country. There has been a continuous demand for improved performance of discrimination processing for foreign paper money (ie multinational sovereignty). Accordingly, the conventional high performance banknote processing apparatuses, for example, in the case of a two-pocket banknote counter, when a banknote is put in a state in which several state bills are mixed, in which direction the banknotes are placed in which direction the banknotes are put in any direction. After recognizing whether or not the bill of the paper type corresponding to the state bill of the first inserted bills for the subsequent inserted bills, the normal processing, and if it does not correspond to the national bill of the first inserted bills has a function of reject processing. Such a function may be referred to by various names, but it is referred to as an auto-currency function in the present specification. Without the auto-currency mode, the processing load is very large because not only the first inserted bill but also all the bills must be determined every time. Accordingly, banknote processing apparatuses having an autocurrency mode for performing such an autocurrency function are preferred.

By the way, the conventional banknote processing apparatuses as described above have a problem that the number of types of national right that can be distinguished in the autorun mode can be extremely limited (for example, 5 to 10 countries). Because each country has several kinds of bills, the bills actually distributed in the past must be able to distinguish old bills from the bill handling device, and the user puts the bills in any direction and in any position within a limited processing time. Because you have to be able to determine all of them. In other words, the bill handling apparatuses have a predetermined bill processing speed according to the performance specification (for example, 1,000 sheets per minute), and can easily increase the number of nations that can be discriminated in autorun mode while maintaining the bill processing speed. Because there is not.

For example, if you look at the US dollar bill as an example, there are seven bills distributed in the new priesthood, seven bills distributed in the old bill, and two bills issued in the latest bill. Since the user does not know which of the four directions before, after, left, and right of the banknote, it is the same as that from the viewpoint of the bill handling apparatus, a total of 64 banknote types should be determined even if only the US dollar banknote is used. Therefore, in the autorun mode, the bill handling apparatus does not know which country bills are processed, so the bill handling apparatus automatically inserts the first bill within the limited processing speed (or processing time) in consideration of the number of all these cases. Since it is most important to determine which kind of nation's sovereignty, and it takes a lot of processing time, it is not a property that can easily increase the number of nations that can be discriminated and processed in autorun mode. Of course, assuming that there is a very high-performance bill discrimination algorithm and hardware such as an expensive high-performance processor that operates it smoothly, and if it can be installed in the bill processing apparatus, the number of nations that can be discriminated simultaneously in the autorun mode This problem can be solved by increasing the number of times, but this is only a hope. Even if such hardware and algorithm exist, in reality, the bill processing device field is also becoming increasingly competitive in auto-currency mode. It's not easy to adopt and it's not practical.

Therefore, if the number of nations that can discriminate in auto-currency mode can be greatly increased while employing hardware such as a commercially available processor such as a cost-effective one, the product competitiveness can be further increased and the measure of the performance of the bill handling apparatus can be measured. You will be able to. However, given the recent market demands and trends in which banknote discrimination processing speed is increasingly required (e.g., 10-25 sheets per second), it is possible to shorten the recognition time of the first sovereign banknotes due to the characteristics of the autocurrency function. Since there is a limit, there is a technical limit to increasing the number of nations that can be discriminated in autorun mode. That is, from the viewpoint of the bill handling apparatus, it is not known which country bills are put in, and it is necessary to recognize which country bills are recognized for the first inserted bills that require the most processing time due to the largest number of cases under the fixed bill processing speed. Shortening the time required is a very difficult problem.

On the other hand, recent banknote processing apparatuses have various banknote processing modes for diversifying banknote discrimination and sorting processing in addition to the above autorun mode. For example, a simple counting mode that simply counts how many bills are inserted without determining the number of bills, counts the number of bills to be inserted, recognizes the bills, and calculates the number, amount, and total of each bill. Mode of recognition of paper currency, the mode of judging whether it is suitable for circulation of banknotes such as forgery and damage, as well as the kind of paper currency of the inserted paper money, the user sets one national right to be processed, and performs normal discrimination processing only on the paper money of the set national money. For the banknotes of other nations, the banknote processing apparatus is provided with a single state zone mode for reject processing.

In addition, there are some bill processing apparatuses that are set at the same bill processing speed for such a plurality of types of bill processing modes, and there are bill processing apparatuses in which bill processing speeds are set differently for each mode or only some of the modes. For example, Korean Patent Publication No. 10-1357289 (published date: January 28, 2014), entitled "Bank Identification Counter," includes a plurality of banknote identification modes including a paper seed identification mode in which a banknote identification counter identifies the paper type of a banknote. In the case where a mode other than the paper type identification mode (for example, a simple counting mode) is selected from among the plurality of modes, while controlling the other modes of, the paper money processing speed, which is the number of bills processed per unit time, is made faster than when the paper kind identification mode is selected. A technique for controlling has been proposed. In addition, the Republic of Korea Patent Publication No. 10-0992078 (published date: November 4, 2010), the name of the "note bill discharge accelerator of the bill counter" due to an abnormal phenomenon at the time of inputting the bills and trailing during bill transfer In order to prevent the interference between bills, a technique of controlling the bill conveyance speed faster has been proposed only in the transfer section in which the preceding and following bills are classified while maintaining the counting speed of the bills.

In order to solve the problems of the prior art as described above, the present invention can vary the bill processing speed (or time) for the bills that are initially inserted among the bills put in the predetermined bill processing mode to the extent necessary to secure the national recognition time The object is to provide a bill processing apparatus.

In order to achieve the above object, a bill processing apparatus provided with a plurality of bill processing modes according to the present invention, in a predetermined bill processing mode, by varying the bill processing speed with respect to the bills initially inserted among the bills to be inserted It is characterized by processing.

According to the banknote processing apparatus of the present invention, banknote discrimination in the banknote processing mode through control of varying the banknote processing speed (or time) for the banknotes initially inserted in the predetermined banknote processing mode to the extent necessary to secure the national right recognition time. There is the effect of greatly increasing the number of countries that can be dealt with.

In addition, according to the present invention, the user's work efficiency is ensured, while the price competitiveness of the bill processing apparatus can be increased, the bill discrimination processing time can be saved, and the merchandise is significantly improved.

1 is a block diagram illustrating a schematic configuration of a bill processing apparatus 100 according to an embodiment of the present invention. Since the mechanical structure or shape of the banknote processing apparatus 100 is not highly related to the gist of the present invention, an example thereof will be omitted. In FIG. 1, a bill processing apparatus 100 according to an embodiment of the present invention includes an input unit 10, a conveying unit 20, a driving unit 30, a sensor unit 40, a stacking unit 50, and a control unit ( 60), a configuration including a storage unit 70, an input / output unit 80, and a switching unit 90 is illustrated.

The input unit 10 is disposed at a predetermined position on the outer surface of the banknote processing apparatus 100, and when the user places one or more banknotes on the input unit 10, the input unit 10 is separated from the bottom banknote one by one to separate the banknotes. It is put into the banknote processing apparatus 100 one by one. The banknotes that are input are received by the driving force from the driving unit 30 under the control of the control unit 60 and conveyed along the conveying path (not shown) by the conveying unit 20 at a predetermined banknote processing speed (or conveying speed). After passing through the portion 40 and the switching portion 90 is discharged and loaded in the loading portion (50).

The conveying unit 20 serves to convey the inserted banknotes, and various conveying methods (for example, a belt, a roller, or a mixture thereof) may be adopted. In an embodiment of the present invention, a bill conveying method using a roller will be described as an example. The conveying unit 20 includes a conveying path (not shown), which is a path through which bills are conveyed, and a conveying means (not shown) for conveying bills. In this case, the conveying means has a plurality of driving rollers (not shown) and idle rollers (not shown) in pairs on both upper and lower sides along the conveying path, at intervals considering all kinds of banknote sizes. Configured to be arranged in rows. In addition, the conveying unit 20 may be defined as one conveying section from the position at which the bill is inserted to the position at which the bill is ejected, or may be formed by dividing the conveying section into a plurality of pieces. For example, when the conveying section is divided into a plurality of conveying sections, the conveying path section from the position at which the banknote is inserted to the position before the sensor section 40 is inserted into the conveying section and the rest of the conveying section at the start position of the sensor section 40 (eg, Up to the transfer unit 90 or up to the loading unit 50 inlet) may be divided into a discrimination conveying section or the like. In this case, the 1st conveyance part 22 and the conveyance means formed in an input conveyance section and a conveyance path can be called the 2nd conveyance part 24.

The driving unit 30 includes a motor (not shown), and transmits the rotational force generated from the motor by the control of the control unit 60 to the transfer unit 20 through a gear and a belt (eg, a timing belt). So that the banknotes are conveyed at a predetermined banknote processing speed (or conveying speed). The driving unit 30 may be formed of one motor or two or more motors depending on the implementation environment or design intention or the performance or specification of the bill processing apparatus 100. For example, the driving unit 30 may be formed by dividing each conveying section on the bill conveying path. For example, as shown in FIG. 2, the driving unit 30 passes through the first driving unit 32 for driving the first conveying unit 22 of the feeding conveying section and the sensor unit 40 past the feeding unit 10. It may include a second drive unit 34 for driving the second conveying unit 24 of the discrimination conveying section which is a conveying path section. In this case, the driving unit 30 may further include a third driving unit (not shown) for further subdividing the bill conveying section to drive another third conveying section or driving the stacking section 50. In addition, it may be configured to further include, but it is preferable to employ in consideration of the efficiency according to the specifications of the device. When the plurality of drive units 30 are formed as described above, the control unit 60 changes the initial input banknote, that is, the first input banknote or the first to second input banknotes at a lower speed than the normal processing speed (or conveying speed). When conveyed, the plurality of driving units 30 may be controlled to be maintained at the set processing speed (or conveying speed) in each conveying section for each bill, or in another section, another processing speed (or conveying speed) The plurality of driving units 30 may be independently controlled to convey the bills, or the plurality of driving units 30 may be controlled according to the bill processing mode.

The sensor unit 40 is disposed in a predetermined area on a conveying path (not shown) that passes through the feeding unit 10, and is provided with a plurality of types of sensors (not shown) such as an image sensor, a magnetic sensor, and a thickness sensor. Various sensing processes are performed on the bill and each sensing signal obtained by the bill is transmitted to the control unit 60 to determine the authenticity, type, direction, front and back, affair, serial number, and the like of the bill. The image sensor (not shown) is a device configured to obtain a variety of image information of the bill is formed in a line array type, the image by the visible light reflected from the front and / or back of the bill, the image by the visible light passing through the bill, bills Obtain at least one bill image information of an image by infrared rays reflected from the front and / or rear surface of the image, or an image by infrared rays passing through the banknote. In some cases, it may be configured to further acquire reflection or transmission image information by ultraviolet rays. The magnetic sensor (not shown) detects the magnetic component contained in the banknote and transmits a detection signal to the control unit 60 to determine the authenticity. The thickness sensor (not shown) is a stack of banknotes or a foreign material such as a tape or the like. Detects and transmits a detection signal to the control unit 60. In addition, the sensor unit 40 may further include or variously modify various sensors according to design intent and implementation environment.

The stacker 50 is configured to include one or more pockets (or stackers) such that the banknotes are discharged in accordance with the discrimination result after the discrimination processing on the banknotes. When the stacking unit 50 is composed of a plurality of stacking units, the stacking unit 50 is determined to be undeterminable, or determined to be counterfeit, or unsuitable for distribution (damage, contamination, etc.), or is determined to be a double sheet, or a user. A first stacking portion (e.g., a reject pocket portion) (not shown) for discharging and stacking banknotes corresponding to a predetermined discharge classification standard set by the user, and the banknote discrimination results are discharged to the first stacking portion described above. In other cases except when it is to be processed, i.e., when it is determined as a normal processed banknote, as determined by the appropriate country or class, or when determined as a banknote suitable for distribution, or according to another predetermined loading classification standard set by the user. And a second stacking portion (eg, a stacker portion) for identifying and stacking corresponding banknotes. The stacking unit 50 may be configured as three or more in addition, and may be configured in different shapes or manners according to the intended stacking amount, and each stacking unit 50 selects bills according to the determination result. It can be loaded by classifying it according to the attributes of the set or the sorting criteria (for example, class, direction, front and back, national right, authenticity, error, oral, etc.). As the stacking unit 50 is composed of several pieces, the bills may be sorted by several sorting criteria at one time.

The control part 60 controls the drive part 30, and changes the processing speed (or conveyance speed) of the banknote injected. That is, the controller 60 may vary the processing speed (or conveying speed) of bills through the conveying part 20 connected to the driving part 30 by controlling the rotational speed of the driving part 30 (eg, the driving motor). . The controller 60 controls the driving unit 30 when the banknote processing apparatus 100 is set to a predetermined banknote processing mode (for example, an autorun mode) by an operation of the user's input / output unit 80. Among the banknotes to be input in (10), the first banknote is variable at a first speed which is lower than the normal processing speed (or conveying speed) and conveyed, and the second input banknote is controlled to control the drive unit 30 to control the normal processing speed (or Conveying speed). Alternatively, the control unit 60 controls the first input bill at a first speed lower than the normal processing speed (or conveying speed), and the second input bill at a lower speed than the normal processing speed (or conveying speed) and faster than the first speed. It can also be made variable and conveyed at a 2nd speed, and can be conveyed by a normal processing speed (or conveyance speed) from a 3rd input banknote. Similarly, further subdividing allows the input banknotes to vary processing speed (or conveying speed) (eg, third speed) from the first banknote to the majority banknote below the normal processing speed (or conveying speed) More bills to be transported at a lower speed than the speed (or conveying speed) will affect the throughput per unit time, so that only the first of the bills will be slowed down or to the second or third bill (i.e. for the initial bill). Therefore, it is preferable that the user does not experience a decrease in bill processing speed and does not have a substantial effect on the throughput per unit time. In addition, the first to third speeds described above are controlled by the controller 60 within a range necessary to secure the time required for recognizing the national right.

At this time, it can be said that the normal processing speed (or conveyance speed) mentioned above means the banknote processing speed (or conveyance speed) prescribed | regulated by the performance specification of a banknote processing apparatus. That is, the normal processing speed (or conveying speed) is the set banknote processing speed (or conveying speed) in the bill processing mode if the bill processing speed (or conveying speed) is set differently for each bill processing mode or in a particular bill processing mode. ), And when the same bill processing speed (or conveying speed) is set in all bill processing modes, the bill processing speed (or conveying speed) is indicated. For example, some banknote processing apparatuses may equally define the bill processing speed (or bill conveyance speed) at the rate of 900 sheets per minute in all the bill processing modes provided, and another bill processing apparatus may be bill processing speed. Can be defined differently at a speed of 1500 sheets per minute in the simple counting mode, 1000 sheets per minute in the paper type recognition mode, and 600 sheets per minute in the ortho mode. Thus, the banknote processing speed predetermined about the banknote processing mode is a normal processing speed (or conveyance speed).

In addition, the control unit 60 analyzes the sensing signal received from the sensor unit 40 for the inserted banknotes and performs various discrimination processes. For example, the control unit 60 calculates the number and amount of bills to be input, the subtotals and the grand totals for each kind of bills, and a plurality of types (visible light, infrared light, etc.) acquired even when mixing different types of bills into various countries (or volumes). Recognize the country and volume of the banknote from the banknote image of the banknote), determine whether or not forgery is made through a predetermined sensing signal (for example, magnetic signal, ultraviolet signal, infrared signal, etc.), and recognize the serial number of the banknote. Extract or store only images in the serial number area, store them, sort them, search and / or transfer them, and separate new and old bills of banknotes, separate front / back / up / down bills, and bills of various types Separate and extract only the types of notes you want, insert the notes of various types, extract the notes corresponding to the desired amount, and normalize the damaged notes such as old, torn or contaminated And distinguished from the paper money and performs classification and discharge of the load, such as the ability of the paper currency discrimination result according to various criteria, such as extraction, above.

In addition, the control unit 60 decrypts communication and commands between various components of the bill processing apparatus 100, performs arithmetic logic operations, various data processing or control, and controls each component of the bill processing apparatus 100 as a whole. Overall control and processing related to the operation of the banknote processing apparatus 100 such as controlling the operation, grasping the state of the banknote being conveyed or the current operating state of the apparatus, performing an appropriate corresponding operation, and displaying it through the input / output unit 80. Perform

The storage unit 70 controls the driving unit 30 according to the bill processing mode and information related to the operation of the bill processing apparatus 100 together with various information generated by the sensor unit 40 under the control of the controller 60. It stores the log information such as information to be done, set values of each sensor, counting result, orthodontic result, device operation rate and utilization rate, and error code. In addition, the storage unit 70 includes setting data for which the user changes the setting, various data necessary for the operation of the bill processing apparatus 100 and bill processing, SW programs, national rights recognition, book classification recognition, orthodontic determination, counterfeit discrimination, banknotes. Various reference information and discrimination algorithms used for various bill discrimination processing such as direction discrimination and serial number recognition are stored, and are read out and provided under the control of the controller 60 when necessary. In particular, the storage unit 70 controls the driving unit 30 in the predetermined banknote processing mode (for example, the autorun mode) to insert the initial banknote, that is, the first (and / or second to third, etc.). Information for varying the processing speed (or conveying speed) of the bill is stored, for example, in the form of a lookup table.

The input / output unit 80 is provided on the front surface of the banknote processing apparatus 100, and typically includes a display unit (not shown) such as an LCD, an LED, or an OLED, and controls or sets a user for the banknote processing apparatus 100. Or a function of outputting an operation state of the device and a bill processing result (for example, error information, authenticity, number, volume, amount, etc.) under the control of the control unit 60. The input / output unit 80 may further include one or more buttons (not shown) for inputting, setting, and manipulating a predetermined command according to an operation state displayed on the display unit. When the display unit is a touch screen type, the button may be provided as an icon or a menu on the display unit, or may be provided as one or more push buttons near the display unit. In addition, the input / output unit 80 may be integrally formed with the bill processing apparatus 100 or may be formed as a detachable or separate independent peripheral device having a communication function and connected by wire or wirelessly. May be As described above, the input / output unit 80 enables the bill processing mode of the bill processing apparatus 100 to be changed to a predetermined bill processing mode (for example, an autorun mode) by a user's manipulation.

The transfer part 90 is provided when the banknote processing apparatus 100 is equipped with the some loading part 50. That is, the banknote processing apparatus 100 having one stacking unit 50 may omit the transfer unit 90. The transfer unit 90 is disposed at a predetermined position on the banknote conveying path past the sensor unit 40 and operated by the control of the controller 60, and stacks the banknote according to the banknote discrimination result in any one of the stacking units 50. The discharge path is disposed at a position where the conveyance path is branched, and is formed at a predetermined position according to the number of the mounting portions 50. In particular, the transfer unit 90 after the banknote passes through the last sensor of the sensor unit 40, the control unit 60 outputs the determination result to determine from which loading unit to discharge the banknote from the last sensor as long as necessary It is preferably formed at a position to secure the distance of.

Now, operation of the banknote processing apparatus 100 of the present invention will be described.

The banknote processing apparatus 100 of the present invention includes a plurality of banknote processing modes, and in a power-on state, a user performs an autorun mode among the banknote processing modes through an operation of the input / output unit 80. When the banknote processing apparatus 100 is selected, the banknote processing device 100 completes the preparation for performing the autorun mode under the control of the controller 60. Alternatively, even if the user does not operate the input / output unit 80 additionally, if the auto-run mode is set in advance, when the power is turned on, the control unit 60 is ready to perform the auto-run mode. Is done.

The user places a plurality of bills to be processed on the input unit 10 of the banknote processing apparatus 100 in a state in which several national rights are mixed or whether other national rights are mixed. At this time, it is detected by the bill detection sensor (not shown) disposed at a predetermined position on the input unit 10 to detect that the bill is placed on the input unit 10 and the control unit 60 received this detection signal The control unit 30 controls the drive unit 30 to automatically feed the sheet bill into the bill processing apparatus 100 one by one. The bills thus put are conveyed along the conveying path by the conveying unit 20.

In the auto-currency mode, the bill processing apparatus 100 first recognizes which bill of the country bill is the first bill to be inserted when the user puts the bills on the input unit 10 regardless of how the bills are mixed in any direction. After the banknotes that are introduced afterwards are bills of the kind that corresponds to the national bill of the first banknote, the banknotes are normally processed and discharged into a predetermined stacking unit 50. If the banknotes do not correspond to the national banknotes of the first banknote, the stacker 50 Discharge into another stacking portion (50). At this time, the banknote processing apparatus 100 controls the conveyance speed (that is, the banknote processing speed) of the banknote initially introduced by the control unit 60 controls the drive unit 30.

More specifically, referring to FIG. 3, in the general banknote processing mode (eg, FIG. 3A), the banknote processing speed (or conveying speed) from the first banknote to the nth banknote The bills are conveyed at the normal processing speed (or the conveying speed) V substantially the same without a change of. In the case of a predetermined bill processing mode (e.g., auto-currency mode), the bill processing apparatus 100 varies the first inserted bill at a first speed V1 which is lower than the normal processing speed (or conveying speed) V. The controller 60 determines which of the countries (for example, tens of countries) mounted on the device belongs to the country, and performs a series of discrimination processing such as winding, counterfeiting, and filing of the first banknote. While proceeding, the control part 60 controls the drive part 30 from the 2nd input banknote, and continuously feeds and conveys it to a nth banknote at a normal processing speed (or conveyance speed) V (FIG. 3 (b)). Alternatively, the banknote processing apparatus 100 sets the first input banknote at the first speed V1 which is lower than the normal processing speed (or the conveying speed) V, and the second input banknote at the normal processing speed (or the conveying speed). It can also be made to convey at the 2nd speed V2 which is slower than (V) and faster than the 1st speed V1, and conveys at the normal processing speed (or conveyance speed) V from the 3rd banknote.

Similarly, the processing speed (or conveying speed) is further subdivided to vary the input bills from first to multiple times, thereby varying the processing speed (or conveying speed) (such as the third speed) below the normal processing speed (or conveying speed). However, more bills to be transported at a lower speed than the normal processing speed (or conveying speed) will affect the throughput per unit time. Alternatively, it is preferable that the conveyance is changed at a lower speed than the conveying speed so that the user cannot feel the decrease in the bill processing speed and there is no substantial effect on the throughput per unit time.

Here, the first speed V1 is preferably set in advance so as to be controlled by the controller 60 within a time range necessary to recognize which banknote belongs to the first bill. In this case, when the first speed V1 is variably controlled at too low speed, the sensors of the sensor 40 may deteriorate sensing performance or sensitivity depending on the type of sensor (eg, a magnetic sensor). Note that it is desirable to variably control the range in which the sensing performance or sensitivity is maintained.

When the banknote processing apparatus 100 that performs a predetermined banknote processing mode (for example, an autorun mode) does not know which banknote of which country bill is put, the controller 60 recognizes the banknote of the first bill inserted. Is the bill of which country bill compared to the respective reference information for the bill types of all the country bills (for example, tens country bills) stored in the storage unit 70 through the sensing information acquired from the sensor unit 40. The most processing time is required because it must be recognized, so that the conveyance speed (ie, bill processing speed) of the initial banknote (such as the first and / or second and third bills) is slower than the normal processing speed (or conveying speed). By controlling, the number of nations that can be processed in autorun mode can be increased by that much. In other words, in the conventional banknote processing apparatus, if the number of state rights that can be processed in the autorun mode is only about ten, the present invention has the effect of increasing the number of state rights that can be processed in the autorun mode to several tens. .

On the other hand, in the autorun mode, the bill processing apparatus 100 may vary the bill processing speed (or conveying speed) of the initial input bill by another method. This will be described in detail with reference to FIG. 4, when the banknote processing apparatus 100 executes the auto-currency mode, the banknote conveying speed of each banknote inserted is maintained at a normal conveying speed, but the first banknote and the second banknote By increasing the time interval (or interval) between bills, the bill processing speed can be varied to increase the number of countries that can be processed in autorun mode. In the auto-currency mode, the processing time of the first banknote is the highest and the second banknote is continuously inserted after a predetermined time interval. Therefore, after the first banknote is inserted, the second banknote is paused and then controlled so as to recognize the first banknote. To secure processing time.

That is, referring to FIG. 4A, immediately after the first banknote is inserted, the driving unit 30 is braked by the control of the control unit 60 so that the conveying unit 20 inserts the second banknote. Delay can be delayed by a short time interval. At this time, the time interval P1 to be delayed is sufficient for the time interval necessary for recognizing the state right of the first inserted banknote, and can be set in advance. After the second banknote is inserted, the time interval P2 between the third banknote and the third banknote P2 is preferably kept the same (P1> P2). In other words, in the autorun mode of the banknote processing apparatus 100, a time interval (or interval between post-banknotes) P1 into which the second banknote is inserted after the first banknote is inserted, is the time interval P2 between the second and third banknotes, and the third. And the fourth time interval between the bills, such as P2 is more variable control than the input time interval between the other bills. On the contrary, in the general banknote processing mode, as shown in FIG. 4B, the time interval P at which the banknotes are inserted, that is, the intervals between the banknotes to be conveyed, is maintained substantially constant.

Since the method as shown in FIG. 4 (a) is to control only the time interval between the first and second input bills while maintaining the bill conveying speed, the user's bill processing speed is not significantly different, and also affects the processing workload. This is the way to make it almost. Similarly, this time, an example of the modification will be described. That is, in this modification, the conveyance speed of the first inserted banknote is also variably controlled as in the above-described example along with the time interval between the first and second inserted banknotes. This modification is explained in more detail.

In the banknote processing apparatus 100, the transfer unit 90 is disposed on the banknote conveying path passing through the sensor unit 40. As the interval between the sensor unit 40 and the transfer unit 90 increases, the determination processing time is secured. This is advantageous, but the length of the conveying path is increased, so that the size of the banknote processing apparatus 100 is increased, and the interval is predetermined when designing the device to be optimized for miniaturization of the device. In the banknote processing apparatus 100, before the first banknote passes through the sensor unit 40 and before reaching the cutout unit 90, a series of discrimination processes such as national right, paper type, forgery, serial number recognition, orthographic discrimination are performed. Must be completed Only when the transfer unit 90 is operated by the control of the control unit 60 to determine which loading unit 50 is classified and discharged according to the determination processing result, the transfer unit 90 transfers before the banknote reaches the transfer unit 90. The unit 90 is guided to the conveyance path opened to discharge the sorting. In addition, since not only the first banknote but also subsequent banknotes continue to be input, the interval between post and forward banknotes should be considered together with the discrimination processing time.

In this modified example, in order to increase the number of the country bills which can be distinguished from banknotes in the autorun mode (for example, up to several tens), the control unit 60 controls the control unit 60 after the first banknote input in the discrimination conveyance section. By varying (reducing, stopping or delaying) the conveyance speed of the first banknote, the first banknote is compared and analyzed with reference information, for example, several dozen countries, stored in the storage unit 70, to determine which country, and then again. It is restored at the normal conveyance speed and is conveyed to be discharged according to the guide of the switching unit 90, at this time, from the second input bill is processed while maintaining the conveyance rate at the normal conveyance speed, thereby improving the work efficiency of the user.

In addition, in the present modification, the control unit 60 also controls the second inserted banknote when the first inserted banknote is variable (decelerated, stopped or delayed) for a predetermined time interval (for example, several tens of ms) in a predetermined conveying section. The drive unit 30 may be braked by a predetermined time interval by controlling). This can be effective in the case of a high-speed bill processing apparatus to prevent a collision with subsequent bills inserted or to secure a discrimination time when the first inserted bill is variable (decelerated or stopped or delayed) in the discrimination conveying section. Of course, it is also possible to vary (decelerate or stop or delay) only the first input banknote in the discrimination conveying section within the time interval between the post-loading banknotes as described above. How to modify and apply the present modification can be determined according to the specification of the banknote processing apparatus or the number of national rights mounted therein. Also. By the control of the control unit 60, the transfer speed is decelerated within the range in which the sensors of the sensor unit 40 maintain the sensing performance with respect to the first input banknote in the discrimination conveying section, and after the sensor unit 40 is transferred, the transfer is performed. In the section up to the unit 90, delay or stop until a series of discrimination processing such as national right discrimination and class discrimination is completed, and the conveying speed can be restored and returned and processed at normal processing speed for subsequent input bills. have. At this time, it is natural that the input interval may be increased or delayed for the second input banknote as described above.

Further modifications are also possible. That is, the size of the number of nations or the kind of the state right that can be discriminated in the autorun mode mounted on the bill processing device at the request of the user environment or the user's request where the bill processing device is operated is determined as an option. You may lose. This is because the number of different kinds of nations varies, so the degree of loading of many kinds of nations is as important as the number of nations. This modified example variably controls the bill processing speed with respect to the initial banknote according to the magnitude | size (or the designation of the kind of a state right) of the number of state right which can be discriminated in the mounted autorun mode.

For example, in the case of the banknote processing apparatus in which the number of the national right which can be discriminated in the autorun mode is mounted on the first scale (for example, 10 national rights), for example, the first (or initial) banknote will be given. In the case of a bill processing apparatus that does not vary the bill processing speed (or conveyance speed) at a normal bill processing speed (V) or is mounted on a second scale (for example, 11 to 20 countries), the first (or initial) ) In the case of the banknote processing apparatus which controls the banknote processing speed (or conveyance speed) variably by the 2nd speed V2 with respect to an input banknote, or is mounted on a 3rd scale (for example, 21-40 countries). The bill processing speed (or conveying speed) can be variably controlled at the first speed V1 for the first (or initial) input bill. In addition, in the case of a bill processing apparatus in which the number of nations that can be discriminated in the autorun mode is mounted on a fourth scale (for example, 41 or more nations), the next bill is inserted after the first (or initial) bill is inserted. Delay (or stop) by a predetermined time interval to be inserted, or the first (or initial) banknote is stopped by a predetermined time interval in the interval from the sensor unit 40 to the front of the transfer unit 90 after the determination process is completed A person skilled in the art can recover the bill at normal processing speed with the bills, or put and return the first (or initial) bill below the normal processing speed, and then delay (or stop) the bills for a predetermined time interval and then load them. In this case, the above-described examples may be embodied in various modifications, modifications, or combinations.

Next, another embodiment of the present invention will be described with reference to FIG. 5. In the case where the bill processing apparatus 100 according to the present invention variably controls and conveys the initial banknote at a lower speed than the normal processing speed (or the conveying speed) in a predetermined bill processing mode (for example, the autorun mode), the sensor unit Predetermined sensors (eg, magnetic sensors, ultraviolet sensors, or thickness sensors) provided in the 40 may cause a difference in sensing sensitivity of the bill, and thus, various determinations such as winding type discrimination, counterfeit discrimination, orthographic discrimination, etc. Since there is a possibility of adversely affecting a predetermined discriminating process among the processes, another embodiment of the present invention provides a bill processing apparatus 100 of the present invention in order to solve the problem of the possibility of deterioration of the discriminating performance according to the variable control as described above. ) Is further provided with an adaptive adjustment unit (65).

In the banknote processing apparatus 100 according to the present invention, the adaptive adjustment unit 65 is formed as a separate component as shown in FIG. 5 and is configured to operate under the control of the control unit 60. Alternatively, the adaptive adjustment unit 65 may be modified to be included in the control unit 60 according to the implementation purpose or the environment so that the control unit 60 may further perform the function of the adaptive adjustment unit 65. In a predetermined banknote processing mode (e.g., an auto-currency mode), the national right determination process for the inserted banknote is performed using the output signals of the sensors provided in the sensor unit 40, which is basically an image through the image sensor. Based processing and other sensors (eg, magnetic sensors, thickness sensors, UV sensors, etc.) based processing.

In such national rights discrimination processing, image-based processing enables acquisition of banknote images of the required quality without significant difference even if the bill processing speed (or conveying speed) is different (for example, slower than the normal bill processing speed). Sensing by the image sensor is possible, but in the case of the other sensors (e.g. magnetic sensors, thickness sensors, UV sensors, etc.) if the bill processing speed (or conveying speed) is more than a certain level difference (e.g., too slow) Variable) The signal acquired by the other sensor may be different from the sensing signal acquired at the normal banknote processing speed (or conveying speed), and the discrimination processing performance may be degraded. Therefore, in this embodiment, in consideration of the possibility of such a problem, the banknote processing apparatus 100 is comprised so that the adaptive adjustment part 65 may be included. The adaptive adjustment unit 65 is a sensing signal and the bill transfer speed (or processing) acquired from the sensors provided in the sensor unit 40 (particularly from a sensor (for example, a magnetic sensor, etc.) affected by variable transfer speed). Speed), and it is designed to adjust (or filter) and maintain the detection performance of various sensing signals even if the bill conveyance speed is variable.

To this end, the storage unit 70 of the banknote processing apparatus 100 calculates a formula to determine how variable the bill conveyance speed is controlled (that is, slower than the normal banknote processing speed) by determining in advance the combination of the country bills to be mounted. The speed control information is stored in the form of a lookup table. Therefore, when the autorun mode is performed, the adaptive adjustment unit 65 receives the speed control information to be variably controlled from the storage unit 70 according to the combination of the state rights as described above, and the country right to be mounted using the same. Based on this combination, it is possible to automatically perform variable control of the bill conveyance speed. Therefore, the influence on the discrimination performance due to the variable control by the adaptive adjustment unit 65 can be minimized. This makes it possible to easily recognize the control range of the bill conveying speed automatically even if the combination of the countries in the country is not known. Otherwise, the inconvenience of having to calculate each time how much the baud rate should be controlled for each country combination.
