DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for coloring a banknote bundle in a case when the cash storage case encounters unexpected damage such as theft while a cash storage case containing a banknote bundle is being transferred. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contaminant ejecting apparatus for contaminating banknotes in a cash storage case that can be contaminated with a contaminant such as a liquid.

[0002]

2. Description of the Related Art Crime prevention measures, such as contaminating banknotes stored in a cash storage case with a contaminated liquid, cannot be used even when the cash storage case is accidentally damaged. It can be a very effective measure in determining the culprit and the culprit. The contaminated liquid ejecting device for banknote contamination used in this security measure must be installed in a cash storage case. Further, it is necessary to detect that damage has been encountered, output a start signal, and start the spraying of the contaminated liquid on the banknote bundle by the start signal. Furthermore, when misconduct is detected, it is necessary that the contaminated liquid storage tank be capable of discharging contaminated liquid into a perforated hole regardless of the posture of the contaminated liquid storage tank, whether it is in the lying posture, the standing posture, or the standing posture. .

[0003] In this kind of polluting liquid ejecting apparatus for banknote contamination, a nozzle is used for spraying the polluting liquid. Further, the contaminated liquid is stored in the contaminated liquid storage tank, and the contaminated liquid is fed from the contaminated liquid storage tank to the nozzle, whereby the spraying of the contaminated liquid from the nozzle is started. .

Conventionally, a contaminant storage tank used in the contaminant injection device for banknote decontamination includes an inflatable and contractible inner container for storing the contaminant, an inner container for accommodating the inner container, and pressurizing and contracting the inner container. And an outer container that forms a pressurized space for the pressure. Then, the opening of the inner container is attached to the inlet port of the on-off valve which is normally kept closed. In addition, there was provided a valve opening mechanism for opening the on-off valve in response to the input of the start signal, and a contaminated liquid distribution pipe connecting the outlet port of the on-off valve and the nozzle.

In such a conventional contaminant injecting apparatus for fouling banknotes, since the inner container of the contaminant storage tank is constantly pressurized by the pressure of the pressurized space, a start signal is inputted to the valve opening mechanism and the start signal is inputted. When the valve opening mechanism opens the on-off valve, the contaminated liquid stored in the inner container is fed to the nozzle from the open port of the inner container through the inlet port, the outlet port of the on-off valve, the contaminated liquid distribution pipe, and from the nozzle. The contaminated liquid is sprayed toward the banknote bundle.

[0006]

However, in the conventional contaminated liquid jetting apparatus for contaminating banknotes, the inner container is pressurized, and the contaminated liquid is discharged from an opening of the inner container to an inlet port of an on-off valve, so that the content of the contaminated liquid is discharged. When the amount of the contaminated liquid stored in the container decreases, the inner container that has been pressurized and deformed due to the posture (directivity) or by accident of the contaminated liquid storage tank may become an inlet port of the on-off valve. May be blocked, the remaining amount of the contaminated liquid may not be discharged from the opening, and the required contaminated liquid may not be supplied to the nozzle, and the contaminated liquid may not be ejected.

The present invention has been made under the above circumstances. Even if the remaining amount is reduced by discharging the contaminated liquid stored in the inner container, the inner container is kept at the inlet port of the on-off valve. To provide a contaminated liquid ejecting device for banknote contamination of a cash storage case in which the remaining amount of the contaminated liquid is discharged from the opening of the inner container in a steady state so as to be ejected from the nozzle without causing a situation in which the contaminated liquid is blocked. With the goal.

[0008]

SUMMARY OF THE INVENTION A contaminated liquid ejecting apparatus for contaminating banknotes according to the present invention is installed in a cash storage case 1. Further, a nozzle 6 for spraying the contaminated liquid onto the banknote bundle M stacked and stored in the banknote storage unit 14 of the cash storage case 1 in response to the input of the activation signal, and a contaminated liquid storing the contaminated liquid fed to the nozzle 6 And a storage tank 2.

In the present invention, the above-mentioned contaminated liquid storage tank 2
Is an inner container 21 that stores and expands the contaminated liquid, an outer container 22 that accommodates the inner container 21 and forms a pressurized space P for compressing and contracting the inner container 21. It has an outlet 24 for the contaminated liquid inserted into the container 21 and stored in the inner container 21 at one end, and a perforated tube 23 having a contaminated liquid through hole 27 opened in the tube wall.
The outlet 24 of the perforated pipe 23 is attached to the inlet port 31 of the on-off valve 3 which is normally kept closed, and opens the on-off valve 3 in response to the input of a start signal. And a contaminated liquid distribution pipe 5 connecting the outlet port 32 of the on-off valve 3 and the nozzle 6.

[0010] In this case, even if the contaminated liquid stored in the inner container is discharged from the outlet of the inner container to reduce the remaining amount, or the contaminated liquid storage tank is in the lying posture. The inner container that is pressurized and deformed is unlikely to block all the holes of the perforated tube, regardless of whether the container is in the upright posture or the inverted posture. In such a situation where the through hole of the perforated pipe is not blocked even when the inner vessel is reduced, the inner vessel is added by appropriately determining the relationship between the length of the perforated pipe and the size of the inner vessel. This is particularly noticeable when folds and wrinkles are formed when compressed and reduced. Therefore, even if the inner container is deformed, the contaminated liquid stored in the inner container enters the internal passage of the perforated pipe through the open through-hole, and then the opening / closing valve of the on-off valve passes through the outlet of the perforated pipe. It is discharged to the inlet port, and is further fed to the nozzle from the outlet port of the on-off valve via the polluted liquid distribution pipe, and is ejected from the nozzle.

The inner container is preferably made of rubber. If the inner container is made of rubber, the pressure in the pressurized space and the elastic return force of the inner container itself help to shrink the inner container and discharge the contaminated liquid. It is possible to keep the pressure in the pressurized space small compared to the case where the contaminated liquid is discharged by shrinking the container, which helps to reduce the pressure resistance of the outer container and reduce the price. .

Here, reference is made to the reference numerals in the drawings, but this is for the purpose of facilitating the understanding of the contents, and is not intended to limit the contents to those shown in the drawings.

FIG. 1 is an external view schematically showing a cash storage case 1 (hereinafter referred to as a "case"). This case 1 is a cash storage case which is attached to and detached from an automatic cash dispenser of a financial institution. Can be used as a cassette. Case 1 in the same figure
Then, the internal space of the case main body 12 is increased by the bill base 13 provided in the box-shaped case main body 12 having an open front surface, and the space above the banknote base 13 and the space below the bank stand 13. 15 are divided. Further, a door 16 is attached to the case body 12 via a hinge (not shown), and the door 16 is opened so that a bill bundle can be put in and out of the bill storage unit 14.

FIG. 2 shows a polluted liquid ejecting apparatus (hereinafter referred to as “ejection apparatus”) installed in the case 1. This injection device has a pollutant storage tank (hereinafter, referred to as a “tank”) 2 that stores the pollutant in a pressurized state. Further, it has an on-off valve 3 and a valve opening mechanism 4 for controlling the opening and closing of the on-off valve 3, and a polluted liquid distribution pipe (hereinafter referred to as “distribution pipe”) 5 communicated with an outlet port 32 of the on-off valve 3. Then, the distribution pipe 5 is connected to the two nozzles 6 and the valve opening mechanism 4
Is controlled by the control device 7, and further includes a fraud detecting means 8 for inputting a start signal of the valve opening mechanism 4 to the control device 7. Then, while the tank 2 is installed in the space 15 together with the on-off valve 3, the valve opening mechanism 4, the control device 7, and the like, the two nozzles 6 are installed in the banknote storage unit 14 in an upright posture, The distribution pipe 5 is connected to the lower end of each of the nozzles 6.

The injustice detecting means 8 is provided for detecting that an injustice such as theft or removal of the case 1 has been performed. The fraud detecting means 8 detects, for example, a linear sensor 81 stretched so as to cover the entire outer wall of the door 16 and the case main body 12, and detects an unauthorized unlocking provided on the door 16 and the case main body 12. For example, a lock switch, a door switch for detecting an unauthorized opening of the door 16, a timer circuit for detecting that the door 16 is left open for a certain period of time or more, and a signal from a door switch or a timer circuit are input. There are logic circuits and the like.

FIG. 5 is a block diagram illustratively illustrating the injustice detecting means 8, the control device 7, and the like. In the figure, 81 is the linear sensor, 82 is the lock switch, 8
3 is the door switch, 84 is a timer circuit, and 85 is a logic circuit. The linear sensor 81 includes the door 16 and the case body 12.
Is broken and pierced by unauthorized means to detect that an illegal act has been performed. Lock switch 8
2 and the door switch 83 are used when the door 16
Detect that such misconduct has taken place when they are fraudulently triggered. Although FIG. 5 shows a case where a plurality of lock switches 82 and door switches 83 are provided, the number can be increased or decreased as necessary. The timer circuit 84 detects, for example, when the two lock switches 82 are not released during the set time. The logic circuit 85 includes a door switch 83
Is detected when an unlocking signal is output from the lock switch 82 when the opening signal of the door 16 is output from the lock switch 82. FIG. 5 shows a case where the buzzer 86 is controlled by the control device 7.

As can be seen from a combination of FIGS. 2 and 5, fraudulent acts are performed when the case body 12 in which the banknote bundle M is stacked and stored in the banknote storage unit 14 is properly closed by the door 16. For example, if the criminal cuts or punctures or smashes the case body 12 or the door 16, forcibly opens the door 16, or attempts to unlock the door illegally, the disconnection of the linear sensor 81 or , Lock switch 82,
Unauthorized operation is detected by the door switch 83, the timer circuit 84, the logic circuit 85, and the like, and the signal is input to the control device 7. Then, the control device 7 inputs a start signal to the valve opening mechanism 4, and the valve opening mechanism 4 operates to open the on-off valve 3 according to the input of the start signal. When the on-off valve 3 is opened in this manner, the contaminated liquid pressurized in the tank 2 is discharged from the on-off valve 3 and the distribution pipe 5.
Through the banknote bundle M from the nozzle 6
The contaminated liquid is sprayed on the end face of the. In addition, in the contaminated liquid,
For example, in addition to red, blue, and yellow colored inks that have excellent permeability to banknotes and do not decolor when washed once with water or the like, transparent inks that can be checked for adhesion by any means are preferably used. .

FIGS. 3 and 4 are sectional views showing the tank 2, the on-off valve 3 and the valve opening mechanism 4 installed in the space 15. As shown in FIG.

The tank 2 includes a rubber inner container 21 such as an expandable and contractible NBR for storing a contaminated liquid (not shown);
An outer container 22 that accommodates the inner container 21 and forms a pressurized space P for compressing and contracting the inner container 21;
And a perforated tube 23 inserted inside the inner container 21. The perforated tube 23 has a length close to the entire length of the inner container 21. The outer container 22 is provided with a pressurized gas filling port 28, and the pressurized gas filling port 28 is closed after filling the pressurized gas. The perforated pipe 23 has a large number of through-holes 27 formed in the pipe wall, through which the contaminated liquid can flow. Further, an outlet 24 provided at one end of the perforated pipe 23 is internally fitted to an inlet port 31 of the on-off valve 3 attached to the mouth 25 of the outer container 22. Between one end of the pipe 23 and the peripheral wall of the inlet port 31 of the on-off valve 3, an opening 26 of the inner container 21 is attached in a pressurized manner.

The on-off valve 3 includes a valve box 30, an inlet port 31 and an outlet port 32 provided in the valve box 30, and a liquid passage provided in the valve box 30 and communicating between the inlet port 31 and the outlet port 32. 33, a valve seat 34 provided in the liquid passage 33, and a valve body 35 which is brought into contact with and separated from the valve seat 34. The valve stem 36 fixed to the valve body 35
Is projected through the through hole 37 of the valve box 30, and the valve body 35 is always in elastic contact with the valve seat 34 by the force of a spring body 43, which will be described later, to keep the valve body closed.

The valve opening mechanism 4 includes a piston 41 fixed to the valve rod 36 and linked to the valve body 35, a cylinder chamber 42 accommodating the piston 41, a piston 41 and the valve box 30. Between the valve seat 35 and the valve seat 34
The valve body 35 resists the force of the spring body 43 by generating a gas in response to the input of the start signal and causing the gas pressure to act on the piston 41. The gas generator 44 is retracted from the valve seat 34 to open the on-off valve 3.

In the injection device described with reference to FIG. 3, when the gas generator 44 generates gas in response to a start signal and the gas pressure presses the piston 41 to retreat the valve body 35 with respect to the valve seat 34, the valve is opened and closed. 3 is opened and the liquid passage 33 is opened.
Opens. On the other hand, since the pressurized space P formed by the outer container 22 is filled with the pressurized gas, when the open / close valve 3 is opened as described above, the pressurized space P is pressurized by the pressure of the pressurized space P. The contaminated liquid stored in the inner container 21 is discharged from the outlet 24 of the perforated pipe 23 to the inlet port 31 of the on-off valve 3 and passes through the liquid passage 33 and the outlet port 32, as described with reference to FIG. It is fed to the nozzle 6 through the distribution pipe 5.

When the contaminated liquid is discharged from the inner container 21, the inner container 21 is pressurized and deformed as the remaining amount of the contaminated liquid decreases. FIG. 4 shows a state where the pressurized inner container 21 is deformed. As shown in the figure, the deformed inner container 21 surrounds the perforated tube 23 so as to surround the perforated tube 23.
3 comes into contact. However, the inner container 2
Even if 1 is deformed, there is almost no possibility that the inner container 21 will block all the through holes 27 of the perforated tube 23. For this reason, the contaminated liquid stored in the inner container 21 is filled with the open through-hole 2.
After passing through the internal passage of the perforated pipe 23 through 7, it is discharged from the outlet 24 of the perforated pipe 23 to the inlet port 31 of the on-off valve 3. Therefore, much of the contaminated liquid stored in the inner container 21 does not remain in the inner container 21 and the loss of the contaminated liquid does not increase. In particular, when the inner container 21 is compressed and contracted, it is preferable that the inner container 21 forms a fold-like wrinkle as shown in FIG. Even if 21 is reduced, it is extremely unlikely that the entire through hole 27 of the perforated pipe 23 will be closed by the inner container 21. In order for the inner container 21 to form a fold-like wrinkle when the inner container 21 is compressed and contracted, the relationship between the length of the perforated tube 23 and the size of the inner container 21 is appropriately determined. It should be left.

[0024]

As described above, according to the present invention, the inner container closes the inlet port of the on-off valve even if the remaining amount is reduced by discharging the contaminated liquid stored in the inner container. Such a situation does not occur, and the remaining amount of the contaminated liquid is discharged from the opening of the inner container in a steady state and injected from the nozzle.
