Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote handling machine,
In particular, the present invention relates to a bill feeding device capable of reliably feeding, one by one, the bills in the bill storage unit from the bill storage unit that stores the bills in a stacked state to the bill transport path.

[0002]

2. Description of the Related Art Conventionally, a bill feeding device for feeding bills one by one to a bill feeding path is disclosed in Japanese Patent Laid-Open No. 146585/55.
No. 6,086,045. The banknote handling machine shown in this publication has a banknote storage section, a banknote payout section (banknote payout device), a banknote discrimination section, a banknote sorting section, and a banknote storage section along the banknote transport path for transporting banknotes. With such a configuration, the banknote payout unit causes the banknotes in the banknote storage unit where the banknotes are stored in an accumulated state to the banknote transport path to have a predetermined interval between the banknotes in the banknote storage unit. Put 1
After paying out one by one, the banknote discriminating section discriminates the denomination, authenticity, damage, conveyance failure (double feed, diagonal feed, etc.) of the banknote, and the banknote sorting section discriminates the banknote discriminating section. Based on the result, the bills are sorted and stored in one of the denomination-based bill storage unit and the reject bill storage unit.

[0003]

By the way, in the banknote handling machine configured as described above, when a near-feed occurs in which the conveyance interval of the banknotes delivered by the banknote delivery section is small, the near-feed is performed. Leading notes and /
Alternatively, even if the succeeding banknotes can be discriminated by the bill discriminating unit, when the preceding bill and the succeeding bills are sorted by the bill sorting unit on the basis of the discrimination result, the conveyance interval required is insufficient. , When near-feed occurs, the two bills, the preceding bill and the succeeding bill, are both rejected, and the processing efficiency of the bills decreases, and the rejected bills must be reprocessed later. There was a problem.

In order to solve such a problem, a bill sorting apparatus disclosed in Japanese Patent Laid-Open No. 6-212418 is provided. This bill sorting device has a position and a gap sensor for detecting the conveyance interval of the bill after the bill has been fed from the bill storage section to the bill conveyance path, and based on the detection signals of these sensors, In the case of near-feed where the interval is small, by lowering the rotation speed of the transport motor that drives the bill transport path, the transport speed of these bills is slowed down. The bills used as the feed are discriminated and sorted without any trouble.
However, in such a banknote sorting device, the rotation speed of the transfer motor is adjusted to change the transfer speed of the entire banknote transfer path. However, if it is performed while the conveyance speed of the bill conveyance path is changing, the discrimination data becomes irregular, which causes a new defect that erroneous discrimination occurs.

The present invention has been made in view of the above circumstances, and adjusts the conveyance interval of bills without changing the rotation speed of the conveyance motors for feeding the bills from the bill conveyance path or the bill storage section. It is an object of the present invention to provide a bill feeding device that can be performed and that can prevent both near feed and erroneous discrimination in the discrimination section.

A clutch that cuts driving force transmission,
It is characterized by comprising a brake that does not exert a braking action to stop the bill feeding unit when the driving force transmission is ON, and a braking action that stops the bill feeding unit when the driving force transmission is OFF.

According to another aspect of the bill feeding device of the present invention, the near-feed detector detects a time interval from when the preceding bill passes the feeding detection sensor to when the succeeding bill is detected by the feeding detection sensor, and It is characterized in that the carrying interval is detected based on the reference carrying interval represented by the stored time data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a banknote handling machine for classifying and storing banknotes in a plurality of denomination storing sections, particularly in the vicinity of the banknote payout device 100. First, in FIG. 1, reference numeral 1
Is a banknote storage unit that is provided on the front side of the machine body 50 and that can stack and mount a predetermined amount of banknotes. In this banknote storage unit 1, banknotes are stacked and mounted and the banknotes are inclined downwardly. The banknote stacking plate 2 and the banknote stacking plate 2 are composed of a banknote stacking plate 2 and a front plate 3 that aligns the downwardly inclined lower ends of the banknotes stacked and stacked on the banknote stacking plate 2. Between the front plate 3 and the front plate 3, there is provided an opening for feeding a part of the stacked bills toward a position where the feeding roller 10 and the separating roller 11 which form the bill feeding unit 6 described later face each other. . Further, an arm 4B, which is rotatably provided around a position-fixed support shaft 4A, and an arm 4 are provided above the bill mounting plate 2.
A bill holding plate 4 is provided at the tip of B so as to be swingable about a shaft 4C and holds the bill on the bill mounting plate 2 from above by its own weight.

Adjacent to the banknote storage unit 1, there is provided a banknote payout unit 6 for separating the banknotes in the banknote storage unit 1 into individual ones and paying them out to a transport path 51 described later. That is, the bill feeding unit 6 is provided at the feeding roller 10 that feeds the bill in the bill storage unit 1 to the conveying path 51 by rotating the bill in the arrow a direction, and at a position facing the feeding roller 10, and is in a stopped state or the feeding roller. Separation roller 11 that separates two or more banknotes by rotating in the direction of arrow b, which is the opposite of 10, or returns to the banknote storage unit 1, and its upper part slightly protrudes on the banknote mounting plate 2. The bill on the bill mounting plate 2 is rotated in the same arrow a direction as the feeding roller 10 to pass through the opening, and the feeding roller 10 and the separating roller 11 provided immediately after the opening face each other. It is composed of a kick-out roller 5 that kicks out toward the user. Further, the bill feeding unit 6 receives the driving force of the feeding motor 7 and drives the feeding roller 10 and the kicking roller 5 to be driven synchronously, and the driving force of the feeding motor 7 is linked to this mechanism. 8 and the electromagnetic clutch 9 for disconnecting the driving force transmission, and when the driving force transmission by the electromagnetic clutch 9 is disconnected, the feeding roller 10 and the kicking roller 5 are connected via the interlocking mechanism 8. It has an electromagnetic brake 12 that forcibly stops the rotation (in this case, the driving force is lost, and it is rotated only by the inertial force).

On the other hand, a pair of upper and lower conveyors are provided on the conveyor path 51 downstream from the position where the supply roller 10 and the separation roller 11 of the paper money supply unit 6 are opposed to each other in the conveying direction by a length of less than one banknote. A conveyance unit 14 which is composed of a belt and holds the fed bills from above and below and which is fed and driven by a feeding motor (not shown) is formed. Further, the feeding roller 10 and the separating roller 11 of the bill feeding unit 6 face each other. And a start end of the transport unit 14 configured by a pair of upper and lower transport belts, preferably near the center thereof, for feeding the bill feeding unit 6 to detect the presence / absence of bills fed onto the transport path 51. A detection sensor 13 is provided. The feeding detection sensor 13 irradiates light, for example, right below, and detects whether or not there is a bill on the conveyance path 51 by the presence or absence of reflected light of this light, and receives the reflected light. Detection ON signal when there is no light and detection OF when no reflected light is received
Based on the F signal, the presence / absence of a bill is detected, and the feeding of the bill is detected by changing the detection OFF signal to the detection ON signal, and the passage of the bill is detected by changing the detection ON signal to the detection OFF signal. The conveyance interval is detected by measuring the time from the bill feeding detection timing to the bill passage detection timing.

Here, the position at which the feeding detection sensor 13 is provided does not come too close to the position where the feeding roller 10 and the separating roller 11 of the bill feeding unit 6 face each other, and the conveying unit 1 is provided.
It is desirable not to come too close to the nipping start ends of the pair of upper and lower conveyor belts that form No. 4. That is, the feeding detection sensor 1
The position where 3 is provided is the feeding roller 10 of the bill feeding unit 6.
If the separating roller 11 and the separating roller 11 come too close to each other, it may not be possible to detect the passage of one banknote. The bill feeding unit 6 separates the bills stored in the bill storage unit 1 into one sheet by the feeding roller 10 and the separation roller 11, but the bills kicked out of the bill storage unit 1 by the kicking roller 5 are It is usually multiple sheets,
The plurality of banknotes kicked out are separated into one sheet by the feeding roller 10 and the separation roller 11.
For example, two banknotes are fed between the feeding roller 10 and the separating roller 11. Of the two banknotes, the banknote in contact with the payout roller 10 side is unwound toward the transport path 51 by the payout roller 10 as it is, and the banknote in contact with the separation roller 11 side has the separation roller 11 in the stopped state. If there is, it stops at that position, and if the separation roller 11 is in the reverse rotation state, it will be returned to the banknote storage unit 1.

At this time, the feeding detection sensor 13 is provided at a position where the feeding roller 10 and the separating roller 1 of the bill feeding portion 6 are provided.
When 1 is too close to the opposing position, when the bill on the separating roller 11 side kicked out together with the bill on the feeding roller 10 side is kicked to the position detected by the feeding detection sensor 13, or Even when kicked out in this way, the banknotes on the feeding roller 10 side are separated from the feeding roller 10 and the separating roller 11 before being returned to a position not detected by the feeding detection sensor 13 by the returning action of the separating roller 11. In the case where the bills have been fed into the conveyance path 51 from the opposing position, this will be referred to as a preceding bill hereinafter, but the passage of the preceding bills will not be detected by the feeding detection sensor 13, and the separation roller 11 side will not be detected. Banknotes, below,
Although this is referred to as a succeeding bill, since the succeeding bill is started to be fed, the position at which the feeding detection sensor 13 is provided does not come too close to the position where the feeding roller 10 and the separation roller 11 of the bill feeding unit 6 face each other. Preferably.

On the other hand, when the position where the feeding-out detection sensor 13 is provided is too close to the nipping start ends of the pair of upper and lower conveyor belts which constitute the conveyor section 14, this is an essential point of the present invention.
There is a possibility that the effect of temporarily stopping the succeeding bill that is likely to be near-fed with respect to the preceding bill cannot be exerted. That is, the transport unit 14 is separated by the banknote feeding unit 6 one by one, holds the leading edge of the bill detected by the feeding detection sensor 13, and transports the bill to the transport path 51 behind it. At this time, when the position where the feeding detection sensor 13 is provided is too close to the transport unit 14, the succeeding banknote determined to be near-feed due to being too close to the preceding banknote is stopped suddenly as described later. In such a case, if the leading edge of the succeeding banknote is pinched by the transport section 14 even if only slightly, it cannot be stopped at the banknote payout section 6,
Since the conveyance path 51 is conveyed before the conveyance interval of the near-fed banknotes can be adjusted to be widened, and the same problem as in the conventional art remains, the position where the feeding detection sensor 13 is provided is It is preferable not to get too close to the section 14.

Therefore, the position where the feeding detection sensor 13 is provided is the feeding roller 10 and the separating roller 1 of the bill feeding portion 6.
1 is preferably provided near the center between the opposing position and the start end of the transport unit 14 constituted by a pair of upper and lower transport belts. To be exact, the separating and feeding capability of the bill feeding unit 6 and the electromagnetic clutch. 9, it will be determined by the response speed of the electromagnetic brake 12.

The conveying path 51 is further constituted by a large number of conveying units 14 not shown, and the pattern of the conveyed bills is optically and magnetically read as discrimination data in the middle thereof, and based on the discrimination data. A discriminating unit mechanism 15 (see FIG. 2) for discriminating the denomination, authenticity, damage, conveyance direction (front / back, forward / reverse) and conveyance failure (double feed, diagonal feed, etc.) of the bill is provided. And in the said banknote processing machine, the sorting fork (not shown) of a banknote distribution mechanism is driven based on the classification result in the classification part mechanism 15, and the banknote after classification is a denomination storage part and a reject storage part ( It is arranged to be sorted and stored in (illustrated portion) or the like.

Next, a control block diagram of the banknote handling machine shown in FIG. 1 will be described with reference to FIG. Reference numeral 2 in FIG.

The ROM 21 is a flowchart (see FIG. 3) to be described later, the authenticity of the banknote by comparing with the discrimination data read by the discrimination unit mechanism 15,
It stores various data such as discrimination reference data for discriminating whether it is a normal loss, a denomination, a conveyance failure, and reference conveyance interval data for determining whether or not the conveyance interval of banknotes is small.

The RAM 22 stores various data such as the number of denominations of bills, the number of unsatisfied bills, the number of counterfeit bills, and the number of occurrences of conveyance failure. The operation unit 23 is configured by a start / stop button operated by an operator, a mode selection switch, and the like, and the display unit 24 displays the current processing content and a failure occurrence location when a failure occurs. Etc. are displayed. Sorting mechanism 25
As described above, the sorting fork (not shown) of the bill sorting mechanism is driven based on the sorting result of the sorting unit mechanism 15 to sort the sorted bills by denomination storing unit and reject storing unit (not shown). ) It is to be sorted and stored.

The storage unit mechanism 26 is composed of a denomination-based storage unit, a group of rollers provided in the reject storage unit, an elevator that can be raised and lowered, and the like. Discrimination Department Mechanism 15
As described above, by comparing the bill discrimination data with the discrimination reference data stored in the ROM 21, the bill is discriminated as to whether it is true or false, whether the bill is defective, the denomination, the conveyance failure, or the like. The feeding unit mechanism 27 is configured by the feeding detection sensor 13, the electromagnetic brake 12, the clutch 9, and the feeding motor 7, and based on the detection signal of the feeding detection sensor 13, the electromagnetic brake 12, the clutch 9, and the feeding motor. 7
Control the behavior of.

Next, the CPU 20 relating to the feeding mechanism 27
The control contents will be described step by step with reference to the flowchart of FIG. First, when executing the flowchart of FIG. 3, the banknotes are placed on the banknote placement plate 2, and the banknote pressing plate 4 presses the banknotes from the upper side. In this state, the feeding motor 7 is driven. By rotating the kicking roller 5 and the feeding roller 10 in the arrow a direction and the separating roller 11 in the arrow b direction, the bills on the bill mounting plate 2 are fed to the bill feeding path 51 one by one. .
Further, at the start of the flowchart of FIG. 3, the clutch 9 is turned on, the feeding motor 7 and the interlocking mechanism 8 of the kick roller 5, the feeding roller 10, and the separating roller 11 are in the connected state, and the electromagnetic brake is used. 12 is turned off, and the feeding roller 10 and the separating roller 11 are in a state in which they can be rotated by the feeding motor 7.

<< Step 1 >> The first bill on the bill loading plate 2 is fed to the bill feeding path 51, and a detection ON signal is output from the feeding detection sensor 13 (the feeding detection sensor 13 outputs reflected light from the bill). Is output when it is detected), the bill passes through the feeding detection sensor 13 and the feeding detection sensor 1
Based on whether the detection signal of No. 3 has changed from the detection ON signal to the detection OFF signal, it is determined whether or not the banknotes fed to the transport path 51 have passed the feeding detection sensor 13. Then, in this step 1, in the case of YES in which the bills delivered to the transport path 51 have passed the delivery detection sensor 13, the process proceeds to the next step 2.

<< Step 2 >> to << Step 4 >> Detection output from the payout detection sensor 13 when the banknote detected in step 1 (hereinafter referred to as a preceding banknote) passes through the payout detection sensor 13. The measurement of the output time of the OFF signal is started (step 2). In the measurement of this detection OFF signal, the next bill (hereinafter referred to as a succeeding bill) is fed out from the bill loading plate 2 and detected by the feeding detection sensor 13.
The process is repeated until the N signal is output (step 3), and the measurement ends when the detection ON signal for the subsequent banknote is output (step 4). << Step 5 >> Then, the output time of the detection OFF signal measured as described above indicates the interval between the preceding bill and the succeeding bill.

<< Step 6 >> The measurement time of the detection OFF signal measured in step 5 is compared with the reference conveyance interval time previously stored in the ROM 21 as the reference conveyance interval data, and the detection OFF is made based on this comparison. If the signal measurement time is less than the reference conveyance interval time, it is determined that near feed has occurred, and the process proceeds to step 4 and subsequent steps. If the detection OFF signal measurement time is equal to or more than the reference conveyance interval time, it is determined to be normal, and the step The process from 1 is repeated. In addition,
In step 1 after passing through step 7, it is determined whether or not the succeeding bill, which has output the detection ON signal in step 1, becomes the preceding bill and the preceding bill has passed through the feeding detection sensor 13. Based on this determination, the process proceeds to the next step 2 and subsequent steps.

<< Step 7 >> The reference transport interval time stored in the ROM 21 and the detected O measured in step 5
The stop time of the succeeding bill is calculated from the difference from the measurement time of the FF signal. It should be noted that this stop time is the time for stopping the succeeding bill until the near feed is avoided and the proper interval can be maintained with respect to the preceding bill. << Step 8 >> to << Step 9 >> Turn off the electromagnetic clutch 9
As F, the drive transmission between the feeding motor 7, the kicking roller 5, and the feeding roller 10 is cut off (step 8), and at the same time when the electromagnetic clutch 9 is turned off, the electromagnetic brake 12 is turned on and the kicking roller 5, Feeding roller 10
Is forcibly stopped (step 9), thereby stopping the feeding conveyance of the succeeding bill. The electromagnetic clutch 9 is O
When the electromagnetic brake 12 is ON in the FF, the succeeding banknote is in a state of being sandwiched between the feeding roller 10 and the separating roller 11.

<< Step 10 >> to << Step 12 >> At the same time, in order to compare with the stop time calculated in step 7, time measurement is started by a timer (step 1
0). It is judged whether or not the calculated stop time matches the time measured by the timer (step 11), and the time measurement by the timer is terminated on the condition that the time measured by the timer matches the calculated stop time (step 1).
2). << Step 13 >> to << Step 14 >> At the same time when the calculated stop time coincides with the measured time, the electromagnetic brake 12 is turned on.
The brake action on the kicking roller 5 and the feeding roller 10 is released as FF (step 13), and then the electromagnetic clutch 9 is turned on to apply the driving force from the feeding motor 7 to the kicking roller 5 and the feeding roller 10. By transmitting (step 14), the feeding operation by the kicking roller 5, the feeding roller 10, and the separation roller 11 is restarted. In other words, the subsequent banknotes are temporarily stopped by the processing of steps 7 to 14 until the conveyance interval with the preceding banknote becomes appropriate.

As described in detail above, in the bill feeding device 100 in the bill processing machine as shown in the present embodiment, the conveyance interval between the preceding bill and the succeeding bill is preset based on the detection signal of the feeding detection sensor 13. When it is determined that the near feed is smaller than the stored reference conveyance interval (step 1 to
In step 6), the stop time of the succeeding bill is calculated from the difference between the pre-stored reference transfer interval and the transfer interval detected by the feeding detection sensor 13 (step 7). Is turned off and the electromagnetic brake 12 is turned on to stop the separation and feeding of one bill by the bill feeding unit 6, and after the lapse of the stop time, the electric brake 12 is turned off and the electric clutch 9 is turned on.
By setting the value to N, the separation and feeding of one bill by the bill feeding unit 6 is resumed (steps 8 to 14), and thus the interval of the near-feed bills is adjusted to an appropriate interval. can do.
Therefore, in the bill feeding device of the present embodiment, it is possible to adjust the feeding interval of bills that are near-feed without changing the rotation speed of drive motors such as feeding motor and feeding motor as in the conventional case, It is possible to prevent the erroneous discrimination in the discrimination unit caused by the change in the rotation speed of the drive motors.

For example, in the banknote storage unit 1, banknotes are stacked on the banknote placement plate 2 so as to be inclined slightly obliquely downward and are pressed by the banknote pressing plate 4 from the upper side thereof, but the invention is not limited to this. Instead of using the bill pressing plate 4, the bills may be stacked by their own weight. Further, the banknote pressing plate that vertically stacks the banknotes and presses the banknotes horizontally may be provided without stacking the banknotes so as to incline obliquely downward.

In the bill feeding unit 6, the feeding roller 10
Although the separating roller 11 is provided so as to be opposed to and stop or rotate in the reverse direction, a separating member that is not a roller may be used. Further, not only the separating mechanism facing the feeding roller 10 but also a part thereof having a comb-like shape may be engaged with the separating mechanism. Further, the kick-out roller 5 is provided on the banknote placing plate 2 such that its upper portion slightly protrudes, but it is attached eccentrically with respect to its rotation axis.

It may be configured to.

In the feeding detection sensor 13, a so-called reflection type sensor is provided. However, the feeding detection sensor 13 is not limited to the reflection type sensor, and a so-called projector and a light receiver are provided so as to sandwich a conveyance path along which bills are conveyed. It may be an opposed type sensor or a drop type sensor. Furthermore, although the transport unit 14 is configured by a pair of upper and lower transport belts, it may be a roller that can sandwich and transport the bills fed from the bill feeding unit 6 to the rear thereof. Of course, it goes without saying that it may be a conveyance section in which a roller and a belt are combined.

A clutch that cuts driving force transmission,
Since it is composed of a brake that does not exert a braking action to stop the bill feeding unit when the driving force transmission is ON and a braking action that stops the bill feeding unit when the driving force transmission is OFF, the succeeding bill is detected by the feeding detection sensor, and the near feed is detected. Immediately at the stage when it is determined that the bill has occurred, the feeding operation of the succeeding bill by the bill feeding unit is suddenly stopped. At this time, the feed detection sensor that takes the near feed detection timing, that is, the sudden stop detection timing,
Since it is provided between the bill feeding unit that is less than the length of one bill and the conveying unit, when the bill feeding unit is suddenly stopped, the feeding action of the succeeding bills must be reliably stopped by the bill feeding unit. Is possible.

In the bill feeding device according to the third aspect, the near-feed detector detects the time interval from when the preceding bill passes the feeding detection sensor to when the succeeding bill is detected by the feeding detection sensor, and Since the conveyance interval is detected based on the reference conveyance interval represented by the stored time data, the conveyance interval data, which is the difference from the reference conveyance interval, immediately indicates the stop time of the succeeding bill by the bill feeding unit. Therefore, the calculation time by the stop time calculation unit can be shortened, and the adjustment operation by the conveyance interval adjustment unit can be promptly performed.
