JP-A-2017-104063

However, since the device of Patent Document 1 is only equipped with an aerosol container, the temperature changes according to the temperature change of the external environment. Therefore, when the air temperature is outside the usable temperature range of the aerosol container, the discharge is affected. For example, when the temperature is such that the contents freeze, the discharge cannot be performed.

Further, in the apparatus of Patent Document 1, the propellant gas is reduced as the aerosol container discharges the contents. In addition, the compressed gas expands as the contents decrease, and the internal pressure of the aerosol container decreases. As a result, the initial velocity at the time of discharge and the dispersability may be lowered, and the discharge performance may be lowered.
Further, even when the aerosol container is not mounted on the flying object, it is necessary to maintain a suitable temperature range and cope with changes in the external temperature.

Hereinafter, the present invention will be described in detail based on the illustrated embodiments.
The dimensions, materials, shapes, etc. of the components described in the following embodiments should be appropriately changed depending on the configuration of the apparatus to which the invention is applied and various conditions, and the scope of the present invention is defined. It is not intended to be limited to the following embodiments.

[Embodiment 1]
First, the overall configuration will be described with reference to FIGS. 1A to 1C. FIG. 1 conceptually shows a ejection device for an air vehicle according to a first embodiment of the present invention, FIG. 1 (A) is a perspective view of the entire air vehicle equipped with the discharge device, and FIG. 1 (B) is an air vehicle. 1 (C) is a cross-sectional view of the discharge device mounted on the vehicle, which is a view of (B) viewed from the C direction.

In FIG. 1 (A), 100 represents an air vehicle. The airframe 100 is an unmanned aerial vehicle such as a so-called multicopter, and the airframe 101 includes a fuselage body 102, four arms 103 radially extending from the fuselage body 102, and legs 107 for takeoff and landing. At the tip of the arm 103, four rotors 104 are provided via a motor 105, respectively. In the illustrated example, the rotary blade 104 illustrates four quadcopters, but various known multicopters such as three (tricopters) and six (hexacopters) can be applied. The yaw axis of the machine body 101 is in the vertical direction of the paper surface, the roll axis is in the horizontal direction of the paper surface, and the pitch axis is in the front and back directions of the paper surface.
A discharge device 1 containing an aerosol container is mounted on the outside of the body 101 of the flight body 100, in the illustrated example, on the lower surface of the body portion 102 via the discharge device support portion 50. The discharge device 1 is a long body, is arranged with the longitudinal direction facing the roll axis direction, and the nozzle 15 projects from the front end portion thereof toward the front of the machine body.

As shown in FIG. 1B, the discharge device 1 has an aerosol container 10 and discharges the contents of the aerosol container 10 in a state of being mounted on the machine body 101. The discharged contents include not only liquid but also gas such as gas and air, powder and the like. Further, for example, a sound (horn) can be discharged by ejecting a gas.
The aerosol container 10 is mounted on the machine body 101 in a state of being housed in the sleeve (accommodating member) 20. The sleeve 20 contains a discharge drive unit 30 for discharging the contents from the aerosol container 10 and a partial configuration of the temperature control device 500. The remaining configuration of the temperature controller 500 is connected to the sleeve 20. The sleeve 20 and the aerosol container 10 can be exchanged as one, and in the following description, the assembly in which the aerosol container 10 is housed in the sleeve 20 is referred to as an aerosol container assembly 40. The configuration of each part will be described below.

[About aerosol container]
The aerosol container 10 is a container that ejects the contents by the gas pressure of the compressed gas or the liquefied gas filled inside, and the existing metal aerosol container can be applied, and the aerosol container 10 is made of a pressure-resistant plastic. A container can also be used. In the aerosol container 10, various actuators having flow paths formed according to the discharge direction and the discharge form are mounted on the stem 12. In the illustrated example, an example in which the actuator 14 is attached to the stem 12 of the aerosol container 10 is shown. The actuator 14 has a configuration including a linear main body portion 14a provided with a straight discharge flow path and a flange portion 14b projecting from the main body portion 14a in a direction perpendicular to the axis. A nozzle 15 having an injection hole 15a (see FIG. 1C) is connected to the main body 14a of the actuator 14 via a connecting tube 16. It is appropriately selected depending on whether the contents are discharged in the form of mist or as a linear jet, depending on the discharge form and discharge direction of the contents.

In the illustrated example, since the aerosol container 10 is horizontally mounted on the lower surface of the machine body 101 and used, as the form of the propellant and the contents to be sealed, the undiluted solution is contained in the inner bag, and the outer circumference of the inner bag and the inside of the container body are used. An isolated type in which the propellant is housed between the circumference and the circumference is used. If it is an isolated type, it can be discharged even if the posture of the aerosol container is sideways (stem position is sideways) or downward (stem position is down).
However, it is not limited to the isolated type, and when the posture of the aerosol container 10 at the time of discharge is such that the stem 12 is used upward, the two-phase or three-phase container and stem equipped with a dip tube are used. When used face down, two-phase and three-phase containers without a dip tube can be applied.

As the propellant carbon dioxide (CO2), nitrogen _(N 2), a compressed gas, such as nitrous oxide _(N 2 O) are preferred. Further, liquefied gases such as general hydrocarbons (liquefied petroleum gas) (LPG), dimethyl ether (DME), and fluorinated hydrocarbons (HFO-1234ZE) can also be applied. However, non-flammable fluorinated hydrocarbons, carbon dioxide, nitrogen, nitrous oxide, etc. are preferable in consideration of fire safety when heating, and nitrogen is particularly preferable in consideration of environmental load. ..

[Structure of sleeve 20]
The material of the sleeve 20 is made of a metal such as aluminum, plastic, or a lightweight material having high strength such as carbon fiber. Further, not only a hard material but also a soft material, for example, a rubber material such as silicone rubber or urethane foam can be used, that is, various materials capable of maintaining the shape of the accommodating portion accommodating the aerosol container 10. Can be used. The term "sleeve" is used to mean a tubular member that houses a cylindrical aerosol container 10.
The sleeve 20 includes a cylindrical sleeve body 21 having a diameter larger than that of the aerosol container 10, a first end cover 22 that covers one end of the sleeve body 21, and a second end cover provided at the other end. It is composed of a part 23.

The first end cover portion 22 is detachably screwed and fixed to the sleeve body 21 via a screw portion, and the second end cover portion 23 is non-removably fixed to the sleeve body 21. .. The second end cover portion 23 and the sleeve body 21 may be integrated.
The first end cover portion 22 has a dome-shaped cover main body 222 and a screw cylinder portion 223 screwed into the female screw portion of the sleeve main body 21. The cover body 222 has a conical or dome-shaped curved surface with a rounded tip, the diameter of which is gradually reduced toward the tip in consideration of aerodynamic characteristics. By forming the shape with good aerodynamic characteristics in this way, the influence of the horizontal wind (crosswind) is reduced, and the flight can be stabilized.

The discharge drive unit 30 is housed in the second end cover unit 23 located on the bottom side of the aerosol container 10. The second end cover portion 23 closes the tubular portion 231 whose one end is fixed to the rear end portion (the end on the bottom side of the aerosol container 10) of the sleeve body 21 and the other end of the tubular portion 231. It is configured to include an end plate 232.

[Support structure of aerosol container 10]
The inner diameter of the sleeve 20 is larger than the outer diameter of the body portion 11a of the aerosol container 10. In the sleeve 20 having this configuration, the aerosol container 10 is positioned by supporting both ends such as the head and bottom by the container holding portion 72 and the first end cover portion 22. As shown in the figure, when the aerosol container 10 is separated and supported from the wall surface of the sleeve 20 at a certain distance, a heat insulating material or a heat storage material can be interposed in the separated space. However, the body portion 11a of the aerosol container 10 may be supported without being separated from the inner wall of the sleeve 20. Further, the temperature control device or the temperature holding device described later may also serve as a member for supporting the aerosol container 10.

As shown in FIG. 2D, a plurality of radial support portions 21a may be provided on the inner wall of the sleeve 20 to support the aerosol container 10 from a direction intersecting the axial direction of the container. In the illustrated example, the temperature control device or the temperature holding device is omitted, but when the temperature control device or the temperature holding device is provided inside the sleeve, the radial support portion 21a and the temperature controlling device or the temperature holding device do not overlap in the axial direction. It is good to provide it like this. On the other hand, when the sleeve 20 also serves as a temperature holding device, the radial support portion 21a can be provided as shown in the illustrated example. The radial support portion 21a supports the aerosol container 10 so as to allow the sleeve 20 to move in the axial direction and prevent the movement in the orthogonal direction. As shown in FIG. 2A, the individual radial support portions 21a may have a support structure that partially contacts the body portion 11a of the aerosol container 10 in a plurality of circumferential directions, or may have an annular wall. It may be configured to support the entire circumference.

The sleeve 20 may have a structure in which a part of the sleeve 20 is ventilated instead of a closed structure. For example, a structure such as a mesh structure or punching can be applied. By doing so, there are effects such as alleviating the self-cooling at the time of discharging the aerosol with the outside air and reducing the weight of the sleeve 20.
The bottom portion 11b of the aerosol container 10 is supported by the container holding portion 72 arranged on the second end cover portion 23 side, and the head side of the aerosol container 10 is a pressing member provided on the first end cover portion 22. Supported by 221.
The pressing member 221 is provided at one end of a tubular body 221a and a first end cover that protrudes from the top of the first end cover portion 22 toward the stem 12 in the central axis direction of the aerosol container 10. It is provided with an end flange portion 221b fixed to the portion 22. A connecting tube 16 connecting the actuator 14 and the nozzle 15 is slidably inserted into the inner circumference of the tubular body 221a of the pressing member 221, and the tip surface of the tubular body 221a is the flange portion of the actuator 14. It is in contact with or in close proximity to 14b. The pressing member 221 may be integrally molded with the second end cover portion 23.

Next, the discharge drive unit 30 will be described with reference to FIGS. 1 (D) to 1 (F).
The discharge drive unit 30 is arranged in the second end cover portion 23 closer to the second end cover portion 23 than the bottom portion 11b of the aerosol container 10. The discharge drive unit 30 is fixed to the second end cover unit 23 and moves the aerosol container 10 along the axial direction to control the discharge and stop of the contents of the aerosol container 10.

The discharge drive unit 30 moves the aerosol container 10 to the axial head side by pushing the aerosol container 10 axially from the bottom portion 11b side. The movement of the aerosol container 10 pushes the actuator 14 against the tubular body 221a of the pressing member 221, and the reaction force pushes the stem 12 into the aerosol container 10 so that the valve mechanism in the aerosol container 10 opens. It has become. When the valve mechanism opens, the contents are automatically discharged by the gas pressure.

The discharge drive unit 30 includes a motor 31 which is a rotation drive source, and a cam mechanism 32 that converts the rotation of the motor 31 into a linear motion of the container holding unit 72. The motor 31 and the cam mechanism 32 are assembled to the frame 301 fixed to the second end cover portion 23. The cam mechanism 32 is provided with a cam 32a that is rotationally driven by the motor 31 and a cam follower 32b that moves along the cam surface of the cam 32a. The rotation of the cam 32a is transmitted to the container holding portion 72 on the judo side via the cam follower 32b, and is moved in a linear direction in the container central axis N direction of the aerosol container 10. The cam 32a in the illustrated example is an egg-shaped disc cam, and the cam axis is orthogonal to the central axis of the aerosol container 10. With this configuration, the rotation of the cam 32a is converted into a linear motion of the aerosol container 10. Since the cam 32a is a disc cam, an urging means such as a spring for constantly bringing the cam follower 32b into contact with the cam 32a is appropriately provided.

Normally, the minimum diameter portion of the cam 32a is in contact with the cam follower 32b, the container holding portion 72 is in the retracted limit position, and the valve mechanism of the aerosol container 10 is held in a closed state (FIG. 1 (D). )). By rotating the cam 32a by the motor 31, the container holding portion 72 advances in the axial direction. That is, the contact position of the cam 32a with which the cam follower 32b abuts at the backward limit position has a small diameter from the center of rotation, and the contact position of the cam 32a with which the cam follower 32b abuts at the forward limit position has a large diameter from the center of rotation. ing. In the illustrated example, the valve is opened not at the maximum diameter portion of the cam 32a but at the transition portion from the minimum diameter portion to the maximum diameter portion, but the valve may be opened at the maximum diameter portion.

[Valve configuration]
FIG. 2B shows an example of the valve mechanism 13 of the aerosol container 10 opened by the discharge drive unit 30.
That is, the stem 12 is provided with a discharge flow path 12a extending by a predetermined dimension in the axial direction from the tip opening, and a stem hole 12b serving as a valve hole is opened on the side surface of the stem 12, and the stem hole 12b is a mounting cup. It is sealed by the inner peripheral surface of the gasket 13a attached to the edge of the insertion hole of 11d.
Normally, the stem 12 is urged in the protruding direction by the gas pressure and the urging force of the spring 13b, and the inner peripheral edge of the gasket 13a serving as the valve body is pressed in the axial direction so that the inner peripheral surface of the gasket 13a presses the valve seat. The valve is maintained in a closed state in close contact with the hole edge of the constituent stem holes 12b.

When the container holding portion 72 moves to the forward limit by the cam mechanism 32 of the discharge driving portion 30, the aerosol container 10 moves to the first end cover portion 22 side, and the flange portion 14b of the actuator 14 moves to the pressing member 221. It comes into contact with the end face, and the reaction force pushes the stem 12 relatively inward of the container. When the stem 12 is pushed in, the inner peripheral edge of the gasket 13a bends toward the inside of the container, the inner peripheral surface of the gasket 13a opens apart from the hole edge of the stem hole 12b, and the contents pushed by gas pressure. Is discharged from the discharge flow path 12a of the stem 12.

The valve mechanism 13 of the illustrated example is an example, and is not limited to such a configuration, and various configurations that normally maintain the valve closed state and open the valve by pushing the stem 12 can be applied. ..
In this example, the cam mechanism 32 converts the rotational motion of the motor 31 into a linear motion, but the present invention is not limited to the cam mechanism 32, and for example, a screw feed mechanism, a rack and a pinion, or the like. Any mechanism that converts the rotary motion of 31 into a linear motion can be applied. Further, instead of a rotary motor, a linear motor for linear drive or a linear drive source such as an electromagnetic solenoid may be used, and the aerosol container 10 may be moved in the axial direction without using a motion conversion mechanism.

[Temperature control device 500]
Next, returning to FIG. 1B, the temperature control device 500 will be described.
The temperature control device 500 of the present embodiment includes a Peltier element (temperature control means) capable of cooling and heating the aerosol container 10. The Peltier element 505 is connected to a power source (not shown) by electrical wiring, and switches between a heating state and a cooling state by changing the polarity of a direct current that is energized according to electrical control.

The Peltier element 505 is connected to a sleeve 20 that houses the aerosol container 10. The hot or cold heat generated by the Peltier element 505 is transferred to the aerosol container 10 by a heat medium. The heat medium is, for example, water or a fluid such as LLC (Long Life Coolant). The heat medium circulates in the circulation path including the reservoir 504 functioning as a tank and the heat medium pipe 502 in contact with the aerosol container 10 by the operation of the heat medium pump 503.
If the contact surface with the reservoir 504 of both sides of the Peltier element 505 is in a heated state, the Peltier element 505 functions as a heating means. On the other hand, if the contact surface is in a cooled state, the Peltier element 505 functions as a cooling means.

The heat medium pipe 502 of the temperature control device 500 provided inside the sleeve 20 is arranged so as to come into contact with the aerosol container 10 when the aerosol container 10 is housed. As the heat medium pipe 502, a material having elasticity and high thermal conductivity is suitable so that it can be used for aerosol containers of various sizes and shapes. Further, in order to increase the contact area with the aerosol container 10, it is preferable that the pipes are connected to each other to form a tubular structure. By using an elastic material as the Peltier element 505 in this way, even when the aerosol container 10 is moved back and forth in the axial direction in order to discharge the liquid material, the heat medium pipe 502 follows the movement. Since it expands and contracts, the contact between the aerosol container 10 and the temperature control device 500 can be maintained.

A heat sink 506 and a fan 507 of the temperature control device 500 are provided on both sides of the Peltier element 505 that are not in contact with the reservoir 504. Thereby, for example, the heat generated from the non-contact surface when the aerosol container 10 is cooled can be released to the outside of the sleeve 20.
Further, by switching the state of the Peltier element using the temperature information acquired by the temperature sensor 501 which is the temperature acquisition means, fine control becomes possible. As the temperature sensor 501, any one such as a thermistor type, a thermocouple type, and a digital type may be used. The configuration of the temperature control device 500 arranged outside the sleeve is preferably stored in the housing 508.

In the illustrated example, the temperature control device 500 is the body portion (that is, the body portion) of the aerosol container 10.
The portion of the aerosol container 10 that is not the tip portion including the nozzle) is heated.
When the temperature control device 500 that heats the body portion is applied to the aerosol container 10 of the type that discharges using the compressed gas, the internal pressure when the aerosol container that uses the compressed gas is heated. Since the amount of increase in the amount of gas rises slowly and it is safer against rapid heating, there is an advantage that the temperature can be controlled safely and efficiently by heating the body portion.
Further, when such a temperature control device 500 is applied to an aerosol container 10 that utilizes liquefied gas, the benefit of temperature control can be preferably enjoyed. That is, in an aerosol container using liquefied gas, when the temperature rises above a certain level (generally, 40 degrees Celsius or less is recommended), the possibility of container deformation and gas leakage due to an increase in gas pressure increases. , The effect of temperature control is high. In addition, when liquefied gas is continuously injected, the heat of vaporization is taken away, which lowers the temperature inside the container and lowers the gas pressure inside, so that the predetermined discharge distance cannot be secured and the contents are placed in unexpected places. Since the possibility of being discharged increases, the effect of temperature control is also high.
As described above, the temperature control device 500 of the present invention can be applied to various types of aerosol containers such as compressed gas and liquefied gas, and in any case, a preferable effect can be obtained.

[Container holder 72]
The container holding portion 72 will be described with reference to FIGS. 1 (D) to 1 (F).
The container holding portion 72 is an annular convex portion that holds a disc portion 72a that abuts on the bottom portion 11b of the aerosol container 10 and an end portion on the bottom side of the body portion 11a of the aerosol container 10 from the outer diameter end portion of the disc portion 72a. It includes a 72b and a connecting shaft portion 72c provided at the center of the surface of the disk portion 72a on the motor side. An anti-slip material 73 that increases the frictional force with the container body is attached to the annular convex portion 72b.

[Configuration example of discharge drive unit]
The discharge drive unit 30 shown in FIG. 1 is an example, and the method shown in FIG. 3 can be applied as a configuration of the discharge drive unit 30. In FIG. 3, the sleeve 20 is shown as a square for simplification.
FIG. 3A shows a configuration in which the actuator 14 side of the aerosol container 10 is fixed to the sleeve 20 and the contact member 30B abutting on the bottom portion 11b of the aerosol container 10 is pushed up by the drive unit 30A. The discharge drive unit 30 in FIG. 1 is an example of this method. In this method, since the actuator 14 side mounted on the stem 12 is fixed, the discharge position accuracy is improved. In addition, it can be used for aerosol containers 10 having various diameters.
FIG. 3B shows a configuration in which the aerosol container 10 is fixed to the sleeve 20 and the stem 12 is pushed down by the discharge drive unit 30 via the actuator 14. That is, the discharge drive unit 30 drives the contact member 30B in contact with the actuator 14 in the direction of being pushed down by the drive unit 30A. In this way, the mechanical mechanism can be concentrated on one side of the aerosol container 10, so that the structure is compact and easy to replace. In addition, it can be used for aerosol containers 10 of various heights.
The structure of the drive unit 30A in FIGS. 3A and 3B may be any mechanism that drives in a linear direction, and motion conversion such as a cam or a screw feed mechanism that converts the rotational motion of the rotary motor in the linear direction. A mechanism can be used, and instead of a rotary motor, a linear motor for linear drive, an electromagnetic solenoid, or the like can be used.
FIG. 3C shows an external valve 30C controlled by an external valve 30C instead of an internal valve of the aerosol container 10. In the figure, the external valve 30C is conceptually described, and can be configured to be opened and closed by an electromagnetic valve or the like. When the external valve 30C is used, since the stem 12 of the aerosol container 10 is only connected to the pipeline 30D, the aerosol container 10 can be easily attached and the opening / closing control can be easily performed. When the existing aerosol container 10 is used, for example, when assembling the aerosol container 10, the stem 12 is pushed in to keep the internal valve in a constantly open state.

[electrical equipment]
Next, returning to FIG. 1A, the electrical equipment for driving the discharge drive unit 30 and the temperature control device 500 will be described. FIG. 1A conceptually describes the electrical equipment mounted on the flying object.

It is provided on the 101 side. Further, the discharge device power supply 211 for driving the discharge drive unit 30 and the temperature control device 500 is a power supply for driving the flying object 100 (assuming that it is incorporated in the flight control unit 110 and is not shown). Is separately provided and mounted on the machine 101 side.

FIG. 2C is an example of sharing the power supply arranged in the flight control unit 110.

[Support structure with the aircraft]
The discharge device support portion 50 that supports the discharge device 1 on the machine body 101 may have, for example, a slide-type fitting structure of a slide rail and a T-shaped groove, or a configuration that can be hung and removed in the rotational direction such as a bayonet coupling. , Screwing, clip coupling, clamps, and various other support means that facilitate removal and attachment can be applied, and the discharge device support portion 50 may be provided with a direction changing device such as a gimbal.
Further, the discharge device support unit 50 is electrically connected to the discharge device control unit 210 and the power supply 211 for the discharge device arranged on the machine body 101 side, the motor 31 of the discharge drive unit 30, the temperature control device 500, and the like. An electric contact may be provided, or the sleeve 20 may be directly connected to a connector arranged on the machine body 101 with a cable or the like. In addition, the sleeve 20 has a power source such as a secondary battery and a wireless communication device, and the electric signal from the flight control unit 110 arranged on the machine body 101 side is transmitted by wireless communication to the discharge device control unit in the sleeve 20. You may send and receive with 210.

Next, the operation of the ejection device of the flying object of the present invention will be described.
[Clearing work]
A replacement aerosol container assembly 40 in which the aerosol container 10 is housed in the sleeve 20 is prepared in advance as shown in FIG. 1 (B). At the time of replacement, the aerosol container assembly 40 is removed from the discharge device support portion 50, and a new aerosol container assembly 40 is attached. Replacing the discharge device support portion 50 can be facilitated by, for example, having a configuration in which the discharge device support portion 50 can be easily attached and detached by manual operation without using a tool. After the replacement, the aerosol container assembly 40 takes out the aerosol container 10 from the sleeve 20 and completely releases the gas and the contents for disposal. The sleeve 20 can be used repeatedly. Further, in this embodiment, only the aerosol container 10 can be replaced while the sleeve 20 is fixed to the machine body 101.

[Spraying work]
Next, the spraying operation involving temperature control will be described with reference to FIG. FIG. 4A is an explanatory diagram showing an example of remote control of a control terminal and an operation terminal of an air vehicle equipped with a discharge device, and FIG. 4B is a simple control block diagram.

-First control example In the spraying work, for example, as shown in FIG. 4 (A), the flight of the flying object 100 is the control terminal 120.
The discharge device 1 and the temperature control device 500 are remotely controlled by the operation terminal 160. The operation terminal 160 is also used as a controller for the camera 106 mounted on the flying object 100. The operation terminal 160 is provided with, for example, a discharge button 163, a stop button 164, a heating button 165, a cooling button 166, and a display 167.

When the operator presses the discharge button 163, the discharge operation is performed. At this time, a discharge command signal is transmitted, received by the discharge device communication unit 212 mounted on the flying object 100, and the contents are discharged. That is, when the discharge button 163 is pressed while viewing the image on the display 167, the discharge command signal is transmitted, received by the discharge device communication unit 212 mounted on the flying object 100, and discharged by the discharge device control unit 210. The unit 30 is driven, the stem 12 of the aerosol container 10 is pushed in, and the contents are discharged. When the stop button 164 is pressed, a stop command signal is transmitted, and the discharge drive unit 30 releases the push of the stem 12 to stop the discharge.

Then, when the operator decides to heat or cool while referring to the current temperature information acquired by the temperature sensor 501 displayed on the display 167, for example, the heating button 165 or the cooling button 166 is pressed. As a result, the temperature control command signal is transmitted and received by the discharge device communication unit 212 mounted on the flying object 100. The temperature control device 500 is driven by the discharge device control unit 210, and a direct current having a predetermined polarity is applied to the Peltier element 505 to start heating. Similarly, when cooling is performed instead of heating, the Peltier element 505 cools according to the pressing of the cooling button 166 by the operator.

Second Control Example Instead of the operator controlling the temperature by using the heating button 165 and the cooling button 166, an input means (for example, a numeric keypad) for inputting the target temperature may be provided in the operation terminal 160. In this case, the target temperature input by the operator from the operation terminal 160 is received by the discharge device communication unit 212. Subsequently, the discharge device control unit 210 controls the energization state of the Peltier element 505 so as to reach the set target temperature by feedback control based on the temperature information detected by the temperature sensor 501, thereby controlling the temperature control device 500. Control.
Instead of setting the target temperature by the operator, a standard temperature suitable for discharging the contents may be set in advance, and the discharge device control unit 210 may continue the control so as to maintain the standard temperature.

Third Control Example The discharge device control unit 210 of this control example has an internal pressure calculating means for calculating the internal pressure of the aerosol container 10 and the content of control by the temperature control device 500 based on the calculated internal pressure (for example, a target). It functions as a control content determining means for determining temperature setting, heating or cooling control, etc.). The method for calculating the internal pressure is arbitrary, but when a general-purpose article is used as the aerosol container 10, a method capable of measuring from the outside of the container such as the discharge device 1, the sleeve 20, and the machine 101 is preferable.
Here, when the volume is constant, the temperature and pressure of the gas are proportional. Therefore, if the temperature of the aerosol container 10 changes due to an altitude change or a climate change of the machine body 101, the internal pressure of the container changes, the initial velocity of discharge and the spraying performance change, and the desired spraying may not be performed.

Therefore, in this control example, the container internal pressure is calculated based on the temperature of the aerosol container 10. The discharge device control unit 210 acquires the temperature information of the aerosol container 10 measured by the temperature sensor 501. Since the temperature and pressure of the gas are in a proportional relationship as described above, the relationship between the temperature and the internal pressure can be obtained by referring to the relational expression or the table. Therefore, the discharge device control unit 210 controls the temperature control device 500 so that the compressed gas has a predetermined internal pressure. For example, when the temperature decrease is measured and it is assumed that the internal pressure has decreased, the discharge device control unit 210 performs heating control until the temperature reaches a desired discharge pressure.
Information for calculating the internal pressure, such as a mathematical formula or table showing the relationship between the temperature and pressure of the gas, and the internal pressure or temperature of the aerosol container 10 suitable for exhibiting the desired spraying performance, is provided in advance in the discharge device control unit. It may be saved in the memory connected to 210, or may be input to the discharge device control unit 210 by the operator. An operation terminal 160 or the like may be used as an input means for inputting such information.

In this control example, the air pressure outside the aerosol container 10 may be further acquired and used for temperature control. That is, even when the air pressure outside the aerosol container 10 changes due to a change in altitude or climate change of the machine body 101, the internal pressure of the container may change, which may affect the initial velocity of discharge and the spraying performance. Therefore, in this control example, the discharge device control unit 210 acquires the atmospheric pressure information by a method such as providing a barometer as the atmospheric pressure acquisition means in the machine body 101 or the operator inputting the atmospheric pressure information via the input means. The temperature control device 500 is controlled to adjust the internal pressure so that a suitable discharge is performed. In this case as well, a mathematical formula or table including the relationship between atmospheric pressure and temperature can be stored and used in the memory.

-Fourth control example When the discharge operation is continued, the contents of the aerosol container 10 decrease. When a separate type aerosol container 10 in which a liquid substance is contained in an inner bag and a compressed gas is contained between the outer circumference of the inner bag and the inner circumference of the container body is used, the inside of the container is reduced as the liquid substance is reduced. The proportion of compressed gas increases, and the compressed gas expands. Then, when the mass is constant, the pressure of the gas is inversely proportional to the volume, so that the internal pressure of the container gradually decreases as the compressed gas expands. The effect of the decrease in internal pressure is small for a while after the start of discharge, but as the amount of discharge increases, the amount of decrease in internal pressure also increases, the initial velocity of the liquid material at the time of discharge decreases, and the sprayability decreases. To do.
Therefore, in this control example, the aerosol container is heated by the temperature control device 500 in order to reduce the influence of the decrease in internal pressure. That is, since the temperature and pressure of the gas are proportional to each other when the volume is constant, the internal pressure can be increased by heating the aerosol container and the pressure of the discharged product can be improved to prevent the discharge performance from being deteriorated.

In this control example, the remaining amount of the contents is measured, the volume occupied by the compressed gas inside the container is calculated based on the remaining amount, and the internal pressure is calculated based on the volume.
Therefore, in this control example, a weight sensor (not shown) is provided on the machine body 101, and the weight of the discharge device 1 including the aerosol container 10 is measured. The measurement may be performed periodically, or may be performed each time the discharge device control unit 210 instructs the discharge to discharge the liquid material. By comparing the weight before the start of the discharge operation with the weight at the time of measurement, the amount of the liquid material used and the remaining amount can be calculated. Then, by calculating the amount of decrease in the volume of the liquid material inside the container based on the density of the liquid material, the volume of the compressed gas can be obtained and the internal pressure can be calculated. In this case as well, a mathematical formula or table including the relationship between the remaining amount and the internal pressure can be stored in the memory and used.
As a method of calculating the remaining amount of the liquid substance, it may be calculated based on the operation history of the discharge drive unit. That is, the timer is started by using the discharge command signal as a trigger, the timer is terminated by the stop command signal to obtain the discharge time, and the usage amount is obtained by multiplying the discharge amount per unit time. Then, the remaining amount is calculated by subtracting the used amount from the initial filling amount. As a result, the internal pressure of the aerosol container 10 can be corrected to obtain a more accurate value.

As described above, according to the discharge device described in the present embodiment, the temperature of the aerosol container 10 can be adjusted. As a result, even if the external environment is an unsuitable temperature for the contents of the aerosol container 10 such as extremely high temperature and low noise, the desired performance can be exhibited. Further, even when the internal pressure of the aerosol container changes due to factors such as the external air temperature and atmospheric pressure, and the decrease in the remaining amount of the liquid substance, the desired performance can be exhibited.
Further, the present embodiment may be regarded as a method for controlling the temperature of the aerosol container using the temperature control device. The temperature of the aerosol container can be suitably maintained by the temperature control device performing a temperature control step including a cooling step or a heating step.

The temperature control device for the aerosol container described in this embodiment and each of the following embodiments can be used even when the aerosol container is not mounted on the flying object. That is, the present invention can be applied to various situations requiring temperature control of the aerosol container. Further, the temperature control method described in each control example using the above temperature control device can also be used even when it is not mounted on the flying object.

Next, another embodiment of the discharge device of the present invention will be described. In the following description, only the parts different from the above-described embodiment will be described, and the same components will be designated by the same reference numerals and the description will be omitted.
[Embodiment 2]
FIG. 5 shows an air vehicle discharge device according to a second embodiment of the present invention. The explanation will be given focusing on the parts different from FIG. 5A is a cross-sectional view of the ejection device of the flying object, and FIG. 5B is a view taken along the line C of FIG. 5A. Note that FIG. 1 (B) is a side sectional view of the discharge device 1 as viewed from the side surface, but FIG. 5 (A) is a plan sectional view of the discharge device 1 as viewed from above.
In the present embodiment, the temperature control device 500 does not heat and is specialized only in cooling. Therefore, it is suitable when the aerosol container 10 is used in an environment where the temperature tends to be high, or when the contents need to be maintained at a low temperature. The same components as those in the first embodiment are designated by the same reference numerals.

In the present embodiment, the cold heat generated by the Peltier element 505, which is a temperature controlling means, is transferred to the aerosol container 10 through the heat conductive plate 522b, the heat pipe 521 and the heat conductive plate 522a, and cools the aerosol container 10. A heat pipe is a highly efficient heat transfer device in which a volatile liquid is sealed as a working liquid in a pipe made of a material having high thermal conductivity. For example, copper is used as the material of the pipe, and ethanol or water is used as the hydraulic solution. In the heat pipe, the hydraulic fluid evaporates on the high temperature side, and heat is transferred by generating a cycle of condensing on the low temperature side. On the other hand, the heat generated from the non-contact surface of the Peltier element 505 that is not in contact with the heat conductive plate 522 is released to the outside by the operation of the heat sink 506 and the fan 507.
The radiator of the heat pipe 521 is preferably located at a position higher than the aerosol container 10 which is a heat source as shown in FIG. 5 (B). With such a configuration, the hydraulic fluid in the heat pipe is condensed by the radiator and flows down to the aerosol container by gravity, so that the hydraulic fluid can be circulated efficiently. Further, by using the heat conductive plate 522, cooling is possible without hindering the back-and-forth movement of the aerosol container 10 even during discharge driving.

As for the temperature control method, the same method as in each control example of the first embodiment can be used. As described above, according to the discharge device described in the present embodiment, the temperature can be lowered even when the temperature of the aerosol container 10 becomes high.

[Embodiment 3]
FIG. 6 shows an air vehicle ejection device according to a third embodiment of the present invention. FIG. 6 is a side sectional view of the ejection device of the flying object.
In the present embodiment, the temperature control device 500 does not perform cooling and is specialized only in heating. Therefore, it is suitable when the aerosol container 10 is used in an environment where the temperature tends to be low, or when the contents need to be maintained at a high temperature. The same components as those in the above embodiment are designated by the same reference numerals.

In the present embodiment, the temperature control device 500 includes a film heater 510 (temperature control means). The film heater 510 is connected to a power source (not shown) by an electric wiring, and functions as a heating means that generates heat when a current is passed according to the control of the control means.

The film heater 510 is arranged inside the sleeve 20 so as to come into contact with the aerosol container 10 when the aerosol container 10 is housed. When the aerosol container 10 is housed inside the sleeve 20, the film heater 510 may be wound around the outer circumference of the container and fixed, or the film heater 510 may be shaped into a cylindrical shape and fixed to the sleeve 20 to fix the aerosol container 10 in a cylindrical shape. May be inserted.
The film heater 510 is preferably flexible so as to correspond to the size and shape of the aerosol container, and for example, a PET film material can be used. In addition, various heaters such as silicon rubber heaters and aluminum sheet heaters can be used according to the required performance and shape. Further, the film heater 510 preferably has a temperature that can be adjusted according to the control of the control means.

As for the temperature control method, the same method as in each control example of the first embodiment can be used. As described above, according to the discharge device described in the present embodiment, the temperature can be raised even when the temperature of the aerosol container 10 becomes low.

[Embodiment 4]
FIG. 7 is a side sectional view showing the ejection device of the flying object according to the fourth embodiment of the present invention. (A) shows a state in which the temperature controller is used for heating, and (B) shows a state in which the temperature control device is used for cooling. In this embodiment, the temperature control device can be used for both heating and cooling manually by the operator. The same components as those in the above embodiment are designated by the same reference numerals.

The temperature control device of this embodiment includes a fixed band 512. The fixing band 512 is arranged on the outer periphery of the aerosol container 10, and the heat generating unit 511 or the cooling unit 515 (temperature controlling means), which is a temperature control unit, can be arranged close to the aerosol container 10. In the illustrated example, the fixing band 512 includes a plurality of slots, and the temperature control unit is housed in each slot and wound around the outer periphery of the container to transfer heat or cold to the aerosol container 10. As the fixing band, a material such as cloth (fiber), rubber, resin, or a combination thereof, which is flexible and can follow the back-and-forth movement of the aerosol container is suitable, but is not limited thereto. Further, the fixing means is not limited to the band shape, and it is sufficient that the heat of the temperature control unit can be transferred to the aerosol container 10. A slot may be provided inside the sleeve 20 so that the heat generating unit 511 can be arranged and fixed.

In FIG. 7A, the heat generating unit 511 is housed in the fixed band 512 as a temperature control unit. As the heat generating unit 511, for example, a portable body warmer that generates heat by oxidizing iron can be used. In FIG. 7B, the cooling unit 515 is housed in the fixed band 512 as a temperature control unit. As the cooling unit 515, for example, a cooling pack that cools by mixing water and a chemical, a cooling agent containing water and a highly water-absorbent resin as main components, and a cooling gel sheet using a polymer gel can be used.

According to this embodiment, a portable body warmer, a cooling pack, or the like can be used as a heating means or a cooling means. Therefore, the aerosol container 10 can be heated or cooled at low cost, and electrical wiring is not required, so that the mechanism can be simplified.

[Embodiment 5]
FIG. 8 is a side sectional view showing the ejection device of the flying object according to the fifth embodiment of the present invention, and conceptually shows the temperature holding device 545 of the aerosol container. In the present embodiment, the discharge performance is maintained by reducing the amount of temperature change rather than adjusting the temperature of the aerosol container 10. The same components as those in the above embodiment are designated by the same reference numerals.

In FIG. 8, the configuration of the sleeve 20 is different from each of the above embodiments. That is, the wall material constituting the sleeve 20 has a three-layer structure, and the aluminum vapor deposition layer 541, the heat insulating material 542 (temperature holding means), and the exterior material 543 are laminated in this order from the inside. As a result, the sleeve 20 also functions as a temperature holding device 545. In this configuration, the aluminum-deposited layer 541 reflects the heat inside the sleeve to prevent heat (hot or cold) from escaping to the outside by radiation, and the heat insulating material 542 prevents heat exchange due to conduction with the outside. Then, the exterior material 543 maintains the sleeve shape. As the heat insulating material 542, various materials such as a fiber heat insulating material such as glass wool and a resin heat insulating material such as foam foam can be used.

According to the present embodiment, since the temperature change of the aerosol container 10 is suppressed by the configuration of the sleeve 20 itself, it is possible to maintain the discharge performance at low cost.
Further, the present embodiment may be regarded as a method for holding the temperature of the aerosol container using the temperature holding device. By performing the temperature holding step by the temperature holding device, the temperature of the aerosol container can be suitably maintained.

-Modification example The configuration of the temperature holding device is not limited to the example shown in FIG.
First, as the arrangement position of the heat insulating material, it can be arranged inside or outside the exterior material, or both. Further, only one of a reflective layer such as an aluminum vapor deposition layer and a heat insulating layer such as a heat insulating material may be provided. By providing the heat insulating material or the like separately from the sleeve 20 in this way, for example, when the heat insulating material deteriorates, only the heat insulating material can be replaced.
Further, the exterior material may be composed of only a heat insulating material. When shock absorption performance is required for the exterior material rather than strength, the exterior material may be composed of only a heat insulating material formed of styrofoam or the like. As a result, the aerosol container 10 can be protected from impact in the event of a crash. Further, urethane foam or the like may be applied as a material having both strength and heat insulating properties.
Further, the aerosol container 10 may be fitted into a heat insulating material formed of styrofoam or the like. In addition, any means may be used as long as the influence of external heat on the discharge device can be suppressed.

[Embodiment 6]
FIG. 9 is a plan sectional view showing a discharge device for an air vehicle according to a sixth embodiment of the present invention, and conceptually shows a temperature holding device for an aerosol container. In the present embodiment, the discharge performance is maintained by maintaining the temperature of the aerosol container 10 at the same level as the outside. Therefore, this embodiment is suitable when the temperature of the external environment is stable and it is necessary to efficiently discharge the heat accumulated inside the discharge device. The same components as those in the above embodiment are designated by the same reference numerals.

FIG. 9 shows a state in which the discharge device is viewed from above. The temperature holding device 555 of the present embodiment is arranged on both side surfaces of the sleeve 20. The temperature holding device 555 includes a vent 551 opened on the side surface of the sleeve 20, a fan 552 (temperature holding means) which is connected to a power source (not shown) by electrical wiring and operates according to a command from a control means, and a fan case 553. Includes. By operating the fan 552, air exchange between the inside and the outside of the discharge device is promoted, and the inside air temperature approaches the outside air temperature.

According to this embodiment, the temperature around the aerosol container 10 can be stabilized in a state close to the outside air temperature. The arrangement and number of fans are not limited to the illustrated examples.

The temperature holding device for the aerosol container described in the present specification can be used even when the aerosol container is not mounted on the flying object. That is, the present invention can be applied to various situations in which the temperature of the aerosol container is maintained. Further, the temperature holding method using the above temperature holding device can also be used even when it is not mounted on the flying object.

The temperature control device and the temperature holding device of each of the above embodiments can be used in any combination as long as they do not conflict with each other. For example, by using a discharge device including both a temperature control device and a temperature holding device, the temperature can be maintained as much as possible, so that the electricity consumption of the temperature control device can be reduced.

In each of the above embodiments, an example in which a multicopter is used as an aircraft on which a liquid material ejection device is mounted has been described, but the moving body ejection device of the present invention can also be applied to a helicopter and has a rotary wing (rotor). It can be applied not only to the aircraft to be used, but also to unmanned aerial vehicles such as fixed-wing aircraft, airships, and gliders, and it can be applied not only to unmanned aircraft but also to manned aircraft. Further, it can be widely applied not only to a flying object but also to various unmanned or manned moving objects such as a vehicle traveling on an orbit and a vehicle traveling on a road surface.
