Description

DETAILED DESCRIPTION OF THE INVENTION +al Technical Field This invention relates to a banknote insertion abnormality detection device for detecting a banknote insertion abnormality in a banknote insertion slot of a banknote deposit and withdrawal machine.

(b) Background of the Invention Conventionally, in bill depositing and dispensing machines, if a bill is inserted into the slot in an inclined state or with the vertical and horizontal directions reversed,
Alternatively, if a different item than a banknote is inserted, problems such as banknote feeding abnormalities or jams occur. Therefore,
It is desired to accurately and easily detect a feeding abnormality without using a special sensor or the like before starting bill feeding from the feeding slot.

(C) Purpose of the Invention In view of the above-mentioned circumstances, the purpose of the present invention is to detect abnormality in the insertion of banknotes by monitoring the state of the insertion detection sensor when the banknotes are transferred internally by the lift mechanism of the insertion slot. An object of the present invention is to provide a bill insertion abnormality detection device that can reliably and easily detect an abnormality in insertion before dispensing banknotes and reliably prevent abnormally inserted banknotes from being fed out or jammed. .

(d) Structure and Effect of the Invention This invention has been made by focusing on the fact that the state of the insertion detection sensor is different until the inserted banknote passes the sensor,
In summary, there is a sensor state monitoring means that monitors the state of the insertion detection sensor until the inserted banknotes pass through the insertion detection sensor by internal transfer by a lift, and a sensor state monitoring means that monitors the state of the insertion detection sensor until the banknotes that have been inserted normally pass the sensor. normal sensor state storage means for storing in advance the state of the insertion detection sensor; and a comparison between the state of the insertion detection sensor monitored by the sensor state monitoring means and the normal sensor state stored in the normal sensor state storage means. and determining means for determining whether banknotes have been inserted normally.

According to the present invention, since a feeding abnormality is detected based on the ON time of the feeding detection sensor until the internal transfer by the lift is completed, the feeding abnormality is detected by using the feeding detection sensor before starting to feed out banknotes from the slot. It is possible to reliably detect a feeding abnormality, thereby reliably preventing the feeding of abnormally inserted banknotes and jams caused by the feeding, and the early detection of feeding abnormalities contributes to improving the reliability of the bill depositing and dispensing machine.

(111 Embodiment) FIG. 1 shows a schematic configuration of the insertion/return opening of a banknote deposit/dispensing machine to which the banknote insertion abnormality detection device according to the present invention is applied.

1 is a banknote feeding position (lift upper point) by a lift mechanism (not shown) and a banknote insertion position (lift lower point) of the slot 9.
This is a lift that goes up and down between. Completion of the movement of the lift to the banknote payout position and the banknote input position is performed by lift detection by a lift upper point detection sensor 6 and a lift lower point detection sensor 7, respectively. When the lift 1 is placed at the banknote payout position, the payout roller 2 feeds out the input banknotes 8 toward the conveyance path 4 side. A conveyor belt 3 conveys banknotes to be returned to the input slot 9 from the conveyance path 4 to the lift 1. Reference numeral 5 denotes a flapper for distributing banknotes to the conveyance path 4 or the conveyance belt 3 side. 81 to S3 are banknote insertion detection sensors provided in the input slot 9, and are arranged in a horizontal row as shown in FIG. 4(A).

FIG. 2 shows an outline of the control system. Reference numeral 10 denotes a control unit composed of a microprocessor, to which are connected a lift drive control unit 11 for controlling the drive of the lift mechanism, sensors S1 to S3, a lift upper point detection sensor 6, and a lift lower point detection sensor 7. There is.

FIGS. 3(A) to 3(C) show the main configuration of the RAM in the control section 10. As shown in FIG. At-A3 is an area of the sensor-on time table. This table area has 1 Rizuto
Data TI, T2°T3 (unit: 20 m5) of the time during which the sensors 81 to S3 are on during a lift down operation in which the lift is lowered from the upper lift point to the lower lift point are stored. This RAM is provided with a counter area L4 (see Figure 3 (C)) that counts up every 2Qma from the start of a $down, and the ON time of each sensor is counted in units of 20Qma by counting in this counter area. Then, the count value is stored in the sensor on-time table as on-time data of each sensor. F1 to F3 are areas of the sensor off flag table, and are flags that are turned on when the sensors S1 to S3 are turned off, respectively.

L1 to L3 store in advance on-time data of sensors used to determine abnormality in supply. Upper limit values α and β (unit: 20 m5) of on-time for each sensor during lift-down operation are stored in areas L'l and L2. The width of the charging hole is checked by comparing the upper limit values α and β with the on-time data of areas A1 to A3. Area L3 is the upper limit value γ of the difference in on time between sensors S1 and 33 during lift-down operation.
(The unit is 20m5) is memorized. The inclination (skew) of the charging hole is checked by comparing the difference in on time during the lift-down operation between the sensors S1 and 83 arranged at both ends with this upper limit value T.

As described above, the loading abnormality detection device according to the present embodiment monitors the status of the loading detection sensor based on the ON time of each sensor during lift-down operation, and also compares the state of each sensor with the normal sensor state during normal loading. The determination is made based on the upper limit values α and β of the on-times of , and the upper limit value T of the on-time difference of the sensors Sl and S3 at both ends as criteria.

When depositing, lift 1 is set at the bill insertion position indicated by the broken line,
After inserting the bill, it descends to the bill payout position indicated by the solid line and transfers the inserted bill inside. When dispensing money, the lift 1 rises from the banknote payout position to the banknote insertion position and deposits the banknotes into the slot 9.
Transfer to.

Next, the process of detecting the state of bill insertion at the insertion/return port at the time of deposit will be described with reference to the flowchart of FIG.

First, in step nl (hereinafter, step ni is simply referred to as ni), the areas of the sensor on time table and the sensor off flag table are cleared.

Next, the lift 1 starts lowering, and the on-time data TI, T2 . T3
and set the 201118 count value T to 0'' (
n2. n3). Next, in steps n4 to n14, time data from on to off of each sensor is obtained in units of 20 m5. That is, as the banknotes on the lift 1 pass through each sensor as the lift 1 descends, each sensor turns from on to off at the end of the passage, a flag corresponding to each sensor is set, and the current 20m5 The count value is stored in the sensor on time table as on time data. lift 1
Stop driving the lift when it descends to the lower point of the lift n15. n16), the process moves on to comparison processing of on-times of n17 and below.

In steps n17 to n19, it is determined whether the on-times T1 to T3 are between the upper limit value α and the lower limit value β, and the width of the closed state is checked. As shown in FIG. 4(A), when the banknotes 12 are inserted in the correct state, β<T1<α
, β<T2<α, and β<T3<α, so the width check is determined to be normal. On the other hand, the fourth
As shown in FIG. 4(B), a bill 13 folded in half is inserted in the longitudinal direction, a bill 14 is inserted in the longitudinal direction as shown in FIG. 4(C), or a bill 14 is inserted in the longitudinal direction as shown in FIG. ), when a wide foreign object 15 other than a bill is thrown in, the above relationship is not satisfied, so it is determined that the feeding is abnormal. In the case of FIG. 4(B), since the banknote 13 is folded in two, the time it takes to pass through each sensor is short and the ON time during the lift-down operation becomes smaller than the lower limit value β. In the case of FIG. 4(C), sensor S3 is not turned on because it is inserted in the longitudinal direction, and the time taken to pass through sensors S1 and S2 becomes longer. Furthermore, in the case of FIG. 4(D), since the foreign object 15 is wide, it takes a long time for it to pass through each sensor.

At n20, a skew check of the charging hole is performed based on the difference in on-time between the sensors S1 and 83. As shown in FIG. 4(A), the banknote 12 that has been normally inserted is not tilted, and the on-time T1 of the sensors S1 and S3. Since T3 is approximately the same and the difference is negligible, and IT1-T31<γ is satisfied, it is determined that the input is normal. On the other hand, Fig. 4 (E) and (F)
When a banknote 16 is inserted at an angle as shown in FIG. Because there is a difference in the time it takes to pass through sensors S1 and 83,
The above relationship cannot be satisfied and it is determined that there is a feeding error.

If the results of the above width check and skew check are normal, it is determined that the banknotes were normally inserted (n21), and the feeding roller 2 starts feeding out the banknotes. If the result of the width check or skew check is abnormal, it is determined that there is an abnormal insertion, and the lift 1 is returned to the bill insertion position to return the inserted banknotes and prompt re-insertion.

With the above operation, an abnormality in bill insertion can be detected by comparing the ON time of each sensor during the lift-down operation. As a result, an abnormality in insertion can be reliably detected before the deposited banknotes are fed out, and the abnormally inserted banknotes or foreign objects shown in FIGS. 4(B) to (G) can be prevented from being fed out to the conveyance path 4 side. It is possible to prevent jams caused by such feeding of banknotes. In addition, the system detects the input using the input detection sensor, and can be configured easily and inexpensively without using any special sensor.

The above n17 to n20 correspond to the determination means of the present invention.
