  However, the contaminant storage container provided in the above-mentioned contaminant jetting device is a pressure-accumulation type that ejects the contaminant with the pressure charged with the contaminant in the container, and the container is constantly pressurized. The entire structure needs to have an advanced airtight structure that is sufficiently airtight, and the structure is expensive. Further, it is difficult to keep the airtightness of the on-off valve sufficiently, and there is a case where the banknotes are unexpectedly soiled due to liquid leakage.

The present invention has been made in order to solve the above-described problems, and the object of the present invention is to provide a normal state by incorporating a contaminated liquid storage bag in which a contaminated liquid is stored in a contaminated liquid storage container. It is necessary to make the inside of the liquid storage container the same as the atmospheric pressure, so that it is possible to prevent the occurrence of liquid leakage, accidental soiling of banknotes, and to improve the airtightness of the entire liquid storage container It is an object of the present invention to provide a pollutant ejecting apparatus that can simplify the design of the container and reduce the manufacturing cost.
Another object of the present invention is to discharge the pollutant liquid which can efficiently compress the pollutant storage bag built in the pollutant storage container with the gas from the gas generator, and can efficiently eject the pollutant liquid. To provide an apparatus.
Still another object of the present invention is to provide a pollutant ejecting apparatus that can prevent the pollutant storing bag from being broken and leaking the sacrificial liquid due to a drop impact or repeated vibration from an unexpected high place.

In order to achieve the above object, the pollutant spray device according to claim 1 of the present invention is characterized in that it is configured as follows.
A gas generator that generates a predetermined amount of gas by inputting an activation signal, a cylindrical-shaped liquid storage container, and connected to the liquid storage container via a pipe, a cash storage case, a case in an ATM device, Or the liquid injection nozzle which sprays a contaminated liquid toward the banknote accommodated in either of the cases in a vending machine is provided. The internal space of the pollutant storage container includes the gas filling chamber filled with gas from the gas generator and the pollutant storage bag built-in chamber containing the pollutant storage bag containing the pollutant. The liquid storage container is partitioned through a movable disk having heat insulation that can move in the container axial direction. The movable disk is movable toward the dirty solution storage bag built-in chamber by the gas pressure generated from the gas generator. The other end of the opening on the opposite side to the gas filling chamber side in the chamber containing the contaminated liquid storage bag is closed with a plug having a liquid outlet communicating with the pipe, and the chamber containing the dirty liquid storage bag is located at the liquid outlet. The mouth portion facing the rim is formed in a sharp edge shape so as to break the contaminated liquid storage bag. An annular protrusion on the inner surface of the spout that faces the chamber containing the contaminated liquid storage bag and projecting in the same direction as the front end on the outer peripheral side of the front end and facing the bottom of the contaminated liquid storage bag And a range including the outer periphery of the bottom portion of the contaminated liquid storage bag that is in contact with the protrusion are fixed with an adhesive.

  According to a second aspect of the present invention, there is provided the pollutant ejecting apparatus according to the second aspect, wherein the faucet is on the inner surface of the plug facing the chamber containing the pollutant storing bag and corresponding to the outer periphery of the tip portion, and the pollutant in contact with the part. Instead of fixing the bottom of the storage bag with an adhesive, a thin circle that is pierced by the tip by being pressed against the tip between the inner surface of the plug and the bottom of the contaminant storage bag The configuration is the same as that of the first aspect of the invention except that the floor plate is interposed and the circular floor plate and the bottom portion of the contaminated liquid storage bag are fixed with an adhesive.

  According to the pollutant jet apparatus of the invention of claim 1, the gas generator is activated by the activation signal to generate gas and fill the gas filling chamber, and the gas pressure acts on the movable disk to move the gas. The gas is compressed between the outer periphery of the movable disk and the inner periphery of the liquid storage container at the same time as the disk moves toward the internal chamber of the liquid storage bag and compresses the liquid storage bag toward the liquid outlet. The contaminant storage bag is vigorously flowed from the gap to compress the contaminant storage bag. The bottom of the compressed liquid storage bag to be compressed is pressed against the sharp edge of the liquid outlet and is broken by the front of the liquid outlet. The bill is sprayed on a bill stored in any of a storage case, a case in an ATM device, or a case in a vending machine.

An annular protrusion that protrudes in the same direction as the tip on the inner surface of the mouthpiece and on the outer peripheral side of the tip, and faces the bottom of the contaminant storage bag, and a contaminant storage bag that contacts the protrusion It is possible to seal the interior of the liquid container storage bag and the liquid outlet in a non-communication state by adhering the bottom part of the container and the range including the outer periphery of the base part with an adhesive, thereby compressing the liquid container bag. Since the gas to be discharged can be prevented from leaking from the liquid outlet, the pollutant storage bag can be efficiently compressed by the gas, and the pollutant can be efficiently ejected.

  In normal times, since the liquid is stored in the liquid storage bag, the inside of the liquid storage container containing the liquid storage bag can be the same as the atmospheric pressure, and the conventional liquid can be pressurized. This eliminates the need for an on-off valve that can cause liquid leakage, such as a pressure-accumulating liquid storage container that stores water, so that this liquid storage container can generate liquid leakage or liquid leakage like a conventional pressure-accumulating liquid storage container. As a result, the unexpected situation of fouling the banknotes is eliminated. In addition, since this pollutant storage container does not require high airtightness unlike conventional accumulator-type pollutant storage containers, it is easy to design and is advantageous in that it can be manufactured at low cost.

  According to the invention according to claim 2, in addition to the above-mentioned effect obtained by the invention according to claim 1, the following effects are also exhibited. In other words, if the bottom of the liquid storage bag is in direct contact with the sharp tip of the liquid outlet, it may be caused by a drop impact or repeated vibration when the liquid spray device is accidentally dropped from a high position during transportation. The contaminated liquid storage bag may be torn at the mouth portion due to rubbing or the like. On the other hand, if a thin circular laying plate is interposed between the inner surface of the plug and the bottom of the contaminated liquid storage bag, it is possible to prevent the contaminated liquid storage bag from being broken at the tip by unexpected drop impact or vibration. It is possible to prevent the leakage of the contaminated liquid. In this case, since the thin circular floor plate is formed so as to be pierced by the tip portion by being pressed against the tip portion, when the pollutant storage bag is compressed by the movable disc and gas, the pollutant storage bag The bottom part of the container is strongly pressed against the sharp mouth part, so that it is broken together with the bottom part of the contaminated liquid storage bag, and the contaminated liquid is ejected from the contaminated liquid storage bag to the liquid outlet.

  A preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a pollutant ejecting apparatus according to an embodiment of the present invention in a state in which a part of a pollutant storage container is broken, and FIG. 2 is a perspective view of a plug incorporated in the pollutant ejecting apparatus of FIG. FIG.

Consists of a liquid storage container 2, a liquid injection nozzle 4 that is connected to the liquid storage container 2 via a flexible pipe 3 and blows the liquid toward a banknote (not shown) in a cash storage case. Is done.

  The pollutant storage container 2 is formed in a bottomed cylindrical shape, and this internal space is movable to the gas filling chamber 5 and the pollutant storage bag built-in chamber 6 so that the inside of the pollutant storage container 2 can move in the container axial direction X. It is partitioned via a disk 7. The movable disk 7 has heat insulation properties such as mica and flame-retardant coated paper to protect a later-described pollutant storage bag 13 from the flame caused by the combustion of the gas generator 1, and is pushed by gas pressure. It is made of a thin and lightweight material so that it can be easily processed.

  In the gas filling chamber 5, the gas generator 1 is installed so as to close one end of the opening of the contaminated liquid storage container 2. The gas generator 1 contains a gas generating agent 8 such as sodium azide, is provided with a starter (electric heating element) 9 for the gas generating agent 8, and includes a lead wire 10 for remotely operating the starter 9. I have. A switch 11 and a power supply 12 are provided in the circuit of the lead wire 10, and a detection signal from the same fraud detection means 17 as the fraud detection means described in Patent Document 1 is input to the control device 18 for control. When the switch 11 is turned on by an output signal from the device 18, the lead wire 10 is energized from the power source 12 to start the starter 9, and the gas generating agent 8 undergoes a property change to generate gas and gas filling chamber. 5 is filled. In addition, the gas generator 1 can also be attached to the exterior of the contaminated liquid storage container 2 in communication with the gas filling chamber 5.

  In the chamber 6 for storing a liquid storage bag, a liquid storage bag 13 storing a liquid such as colored ink is stored. The pollutant storage bag 13 is a resin bag such as polyethylene whose inner surface is vapor-deposited with aluminum. The other end of the opening on the opposite side to the gas filling chamber 5 side in the chamber 6 for storing the contaminated liquid storage bag is closed with a plug 14, and a liquid outlet 15 is provided in the vicinity of the center of the plug 14 so as to penetrate inside and outside. The tip 15 a of the liquid outlet 15 facing the inside of the storage chamber 6 for the liquid storage bag is formed with a sharp edge so as to break the liquid storage bag 13. In the spout 14 illustrated in FIG. 2, the liquid outlet 15 protrudes into a conical shape having a tapered shape toward the inside of the contaminated liquid storage bag built-in chamber 6. The part 15a is formed so that the contaminated liquid storage bag 13 can be easily broken.

On the inner surface of the mouthpiece 14 facing the contaminated liquid storage bag built-in chamber 6 and projecting in the same direction as the tip 15a on the outer peripheral side of the tip 15a, an annular shape facing the bottom 13a of the pollutant storing bag 13 is formed. The protrusion 15b and the range of the bottom portion 13a of the contaminated liquid storage bag 13 in contact with the protruding portion 15b and including the outer periphery 13b of the bottom portion 13a are fixed by the adhesive 19, and the inside of the internal chamber 6 and the liquid storage bag built-in chamber 6 The outlet 15 is sealed in a non-communication state. As the adhesive 19, RTV rubber or silicone adhesive is used.
In this case, as shown in FIG. 3, a circular floor plate 20 is interposed between the inner surface of the plug 14 and the bottom portion 13a of the pollutant storage bag 13, and then the circular floor plate 20 and the pollutant storage bag. It is also possible to fix the bottom portion 13 a of the 13 with an adhesive 19. The circular floor plate 20 is made of paper having a disaster prevention property such as a thin wheeling paper that is pierced by the lip portion 15a by being strongly pressed against the lip portion 15a.

  The liquid outlet 15 is connected to the pipe 3 via a pipe joint 16, and the liquid injection nozzle 4 is attached to the distal end side of the pipe 3.

  In the pollutant ejecting apparatus having the above configuration, when a start signal is input to the gas generator 1, the gas generator 1 ejects a required amount of gas at once, and the gas pressure acts on the movable disc 7 to move the gas. The disc 7 moves toward the contaminated liquid storage bag built-in chamber 6. Along with the movement of the movable disk 7, the pollutant storage bag 13 is compressed toward the liquid outlet 15, and at the same time, the gas flows between the outer periphery of the movable disk 7 and the inner periphery of the contaminant storage container 2. Then, it flows into the contaminated liquid storage bag 13 vigorously and compresses the contaminated liquid storage bag 13. The compressed liquid storage bag 13 is pressed near the center of the bottom 13 a against the sharp edge 15 a of the liquid outlet 15 and broken by the front 15 a, and the liquid in the liquid storage bag 13 is broken. Is ejected from the breakage opening, is pumped to the liquid ejecting nozzle 4 through the liquid outlet 15 and the pipe 3, and can be ejected from the liquid ejecting nozzle 4 toward the banknote.

  In the case where a thin circular floor plate 20 is interposed between the inner surface of the spout 14 and the bottom portion 13a of the pollutant storage bag 13, the center of the bottom portion 13a of the pollutant storage bag 13 compressed by gas is liquid. The circular floor plate 20 is pressed against the sharp edge-shaped mouth portion 15a of the outlet 15 and broken, and after the breakage, as described above, the contaminated liquid in the contaminated liquid storage bag 13 is ejected from the broken opening and the liquid outlet 15 The liquid can be pumped to the liquid jet nozzle 4 through the pipe 3 and ejected from the liquid jet nozzle 4 toward the banknote.

At that time, as shown in FIG. 1, an annular protrusion on the inner surface of the stopper 14 that protrudes in the same direction as the tip 15 a on the outer peripheral side of the tip 15 a and faces the bottom 13 a of the contaminated liquid storage bag 13. 15b and the range including the outer periphery 13b of the bottom 13a of the pollutant storage bag 13 in contact with the protrusion 15b are fixed with an adhesive 19, and the inside of the pollutant storage bag built-in chamber 6 and the liquid outlet 15 Is sealed in a non-communication state, the gas that compresses the pollutant storage bag 13 does not leak from the liquid outlet 15, and the pollutant storage bag 13 can be efficiently compressed by the gas. Can be efficiently ejected.

  As shown in FIG. 3, a circular floor plate 20 is interposed between the inner surface of the plug 14 and the bottom portion 13 a of the pollutant storage bag 13, and the circular base plate 20 and the bottom portion 13 a of the pollutant storage bag 13 are bonded to the adhesive 19. If the container is fixed, the bottom portion 13a of the pollutant storage bag 13 is torn at the tip portion 15a due to a drop impact or rubbing caused by repeated vibrations when the pollutant ejecting device unexpectedly falls from a high position during transportation. Can be prevented as much as possible and leakage of the contaminated liquid can be prevented. Moreover, the gas which compresses the contaminated liquid storage bag 13 does not leak from the liquid outlet 15, but the dirty liquid storage bag 13 can be efficiently compressed by the gas, and the contaminated liquid can be efficiently ejected.

  Moreover, in the contaminated liquid ejection apparatus configured as described above, the contaminated liquid is housed in the contaminated liquid storage bag built-in chamber 6 of the contaminated liquid storage container 2 while being stored in the contaminated liquid storage bag 13 in normal times. Therefore, the inside of the contaminated liquid storage container 2 can be made into a non-pressurized state that is the same as the atmospheric pressure, and the occurrence of liquid leakage is caused like a conventional accumulator-type contaminated liquid storage container that stores the contaminated liquid in a pressurized state. The on-off valve becomes unnecessary. Therefore, the contaminated liquid storage container 2 does not cause a liquid leak like a conventional accumulator-type contaminated liquid storage container or an unexpected situation in which the banknote is soiled due to the occurrence of the liquid leak. In addition, since the liquid storage container 2 does not need to be configured to have a higher airtight structure as the conventional pressure accumulation type liquid storage container, the design becomes easier and can be manufactured at a lower cost.
