[0005] By the way, in the liquid mixing device described in Patent Document 1 mentioned above, a tank and a pump for supplying a cleaning liquid for removing the liquid mixture remaining inside the static mixer are required, and the static mixer is relatively long, making it difficult to make the entire device compact.

[0006] Also, in the liquid mixing device described in Patent Document 1, operations such as removing the liquid mixture using a solvent and disposing of the waste liquid of the liquid mixture and the cleaning liquid are required, which is troublesome for maintenance.

[0007] In addition, the liquid mixing device described in Patent Document 1 has a structure in which the tank for storing the main agent and the tank for storing the additive are exposed to the installation environment outside the liquid mixing device. Therefore, it is easily affected by the temperature of the installation environment, and there is a risk of bias in the quality of the liquid mixture. In particular, when this liquid mixing device is used in a factory or the like where the temperature change is large for each season, the quality of the liquid mixture is likely to be biased.

Embodiments for Carrying Out the Invention

[0013] (One Embodiment) 1. Overview As shown in FIGS. 1 and 2, a liquid mixing device 1 according to an embodiment includes an installation table 2, a main agent injection device 3, an additive injection device 4, a stirring device 5, a moving device 6, a control device 7, and a heat insulation case 8. A container 9 is detachably installed on the installation table 2. The main agent injection device 3 injects the main agent L1 into the container 9. The additive injection device 4 injects the additive L2 into the container 9. The stirring device 5 stirs the main agent L1 and the additive L2 inside the container 9. The moving device 6 relatively moves the stirring device 5 and the installation table 2 between a stirring position where the stirring device 5 is located inside the container 9 and a standby position where the stirring device 5 is located outside the container 9. The control device 7 controls the main agent injection device 3, the additive injection device 4, the stirring device 5, and the moving device 6. The heat insulation case 8 houses the installation table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5. The heat insulation case 8 has an opening 800 through which the installation table 2 is exposed.

[0014] In the liquid mixing device 1 according to an embodiment having the above configuration, after the container 9 is installed on the installation table 2 through the opening 800 of the heat insulation case 8, each device can be automatically controlled by the control device 7 as follows. That is, the moving device 6 relatively moves the stirring device 5 and the installation table 2 so that the stirring device 5 is located inside the container 9. The main agent L1 and the additive L2 are injected into the container 9 by the injection devices 3 and 4. The main agent L1 and the additive L2 inside the container 9 are stirred by the stirring device 5 to form a liquid mixture L3. The moving device 6 relatively moves the stirring device 5 and the installation table 2 so that the stirring device 5 is located outside the container 9. Thereby, in the liquid mixing device 1 according to an embodiment, the container 9 containing the liquid mixture L3 can be taken out from the installation table 2 through the opening 800 of the heat insulation case 8.

[0015] In the liquid mixing device 1 of one embodiment, since it does not include a static mixer, there is no need for a tank or a pump for storing a solvent for cleaning the static mixer, so the entire device can be made more compact. Further, in the liquid mixing device 1 of one embodiment, since there is no need for the operation of cleaning the static mixer or the operation of discarding the waste liquid of the liquid mixture or the solvent discharged from the static mixer, the maintainability can be improved. Further, in the liquid mixing device 1 of one embodiment, the heat insulating case 8 houses the installation table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5. Therefore, in the liquid mixing device 1 of one embodiment, the main agent L1, the additive L2, and the liquid mixture L3 are less affected by the temperature of the surrounding installation environment, and it is easy to suppress the occurrence of bias in the quality of the liquid mixture L3.

[0016] Further, the liquid mixing device unit 100 of one embodiment includes the above-described liquid mixing device 1 and a container 9 detachably installed on the installation table 2 of the liquid mixing device 1. The container 9 has a container body 90 and a holding member 91 that detachably holds the container body 90.

[0017] In the liquid mixing device 1 of one embodiment having the above configuration, for example, a disposable container body 90 can be combined with the holding member 91 for use, and since the cleaning operation of the container body 90 can be omitted, the maintainability can be improved.

[0018] 2. Details Subsequently, the liquid mixing device 1 of the present embodiment shown in FIGS. 1 and 2 will be described in more detail. Hereinafter, each component will be described in detail using the front-rear direction, left-right direction, and up-down direction shown in FIGS. 1 and 2. The liquid mixing device 1 of the present embodiment is a device for forming a liquid mixture L3 composed of a two-component adhesive. The liquid mixture L3 is used, for example, in the batch production of sandwich panels in which a core material is sandwiched between a pair of metal outer skins via an adhesive. The core material is, for example, an inorganic fibrous body such as rock wool, glass wool, or ceramic fiber, or a resin foam such as urethane foam or phenol foam.

[0019] The liquid mixing device 1 further includes a support base 10 in addition to an installation table 2, a main agent injection device 3, an additive injection device 4, a stirring device 5, a moving device 6, a control device 7, and a heat insulating case 8.

[0020] 2-1. Installation Table The installation table 2 is in a tray shape and has a flat plate portion that is rectangular in plan view and a rising wall that protrudes upward from the outer peripheral edge of the flat plate portion. A container 9 is detachably placed on the upper surface of the flat plate portion of the installation table 2.

[0021] The installation table 2 is provided with a positioning portion 20 for positioning the holding member 91 of the container 9. In this embodiment, the positioning portion 20 is a magnet attached to the installation table 2. The magnet is fixed, for example, to the upper surface of the flat plate portion of the installation table 2.

[0022] The installation table 2 is moved by the moving device 6 between a stirring position where the stirring device 5 is located inside the container 9 and a standby position where the stirring device 5 is located outside the container 9.

[0023] 2-2. Main Agent Injection Device The main agent injection device 3 is a device for injecting the main agent L1 into the container 9. The main agent injection device 3 includes a main agent tank 30 for storing the main agent L1, a pump 32 connected to the main agent tank 30 via a pipe 31, and an injection pipe 33 having one end connected to the pump 32 and discharging the main agent L1 from the other end. The driving and driving stop of the pump 32 are controlled by the control device 7 for the main agent injection device 3.

[0024] The main agent tank 30 has, for example, a container-shaped tank body with an open upper surface and a lid for opening and closing the opening of the tank body. The lid is attached to the upper surface of the tank body via a silicone-based packing to ensure airtightness.

[0025] The main agent injection device 3 is installed on the support base 10. In this embodiment, the main agent tank 30 is installed in the upper stage of the rear part of the support base 10, and the pump 32 is installed in the lower stages of the front part and the rear part of the support base 10. The main agent tank 30 and the pump 32 are connected via a pipe 31 connected to the bottom surface of the main agent tank 30.

[0026] The injection pipe 33 is installed on the support base 10 such that the discharge port at the downstream end of the injection pipe 33 that discharges the main agent L1 is located inside the upper part of the container 9 on the installation table 2 when it is at the stirring position.

[0027] The main agent L1 is the main material of the two-component adhesive. Examples of the two-component adhesive include, for example, a solvent-free two-component curable polyurethane-based adhesive. In this case, the main agent L1 is a two-component polyurethane adhesive. The two-component polyurethane adhesive contains, for example, an inorganic filler, phenol, and polyol. The viscosity of the two-component polyurethane adhesive at 20°C is, for example, 8,000 ± 3,000 mPa·s. As the main agent L1, the main materials of other well-known two-component adhesives can also be used.

[0028] 2-3. Additive Injection Device The additive injection device 4 is a device that injects the additive L2 into the container 9. The additive injection device 4 has a structure similar to that of the main agent injection device 3.

[0029] The additive injection device 4 includes an additive tank 40 that stores the additive L2, a pump 42 connected to the additive tank 40 via a pipe 41, and an injection pipe 43 having one end connected to the pump 42 and discharging the additive L2 from the other end. The driving and driving stop of the pump 42 are controlled by the control device 7 for the additive injection device 4.

[0030] The additive tank 40 has, for example, a container-shaped tank body with an open upper surface and a lid that opens and closes the opening of the tank body. The lid is attached to the upper surface of the tank body via a silicone-based packing to ensure airtightness. For example, a nozzle for replacing the air in the tank with dry air is attached to the lid. In this case, the additive tank 40 is suitable for storing the additive L2 such as a curing agent that is easily affected by moisture in the air.

[0031] The additive injection device 4 is installed on the support base 10. In this embodiment, the additive tank 40 is installed side by side with the main agent tank 30 on the upper stage of the rear part of the support base 10, and the pump 42 is installed side by side with the pump 32 on the lower stages of the front part and the rear part of the support base 10. The additive tank 40 and the pump 42 are connected via a pipe 41 connected to the bottom surface of the additive tank 40.

[0032] The injection pipe 43 is installed on the support base 10 such that the discharge port at the downstream end of the injection pipe 43 that discharges the additive L2 is located inside the upper part of the container 9 on the installation table 2 when it is at the stirring position. The downstream end of the injection pipe 43 is arranged such that the rod 50, which will be described later of the stirring device 5, is located between the downstream end of the injection pipe 33.

[0033] The additive L2 is a curing agent that is a material for the two-component adhesive. When the two-component adhesive is a solvent-free two-component curable polyurethane-based adhesive, the additive L2 contains polymethylene polyphenyl - polyisocyanate, 4,4'-diphenylmethane diisocyanate, and isocyanate. The mixing ratio (weight ratio) of the main agent L1 and the additive L2 is, for example, 3:1. As the additive L2, other well-known curing agents can also be used.

[0034] 2-4. Stirring Device The stirring device 5 is a device that stirs the main agent L1 and the additive L2 inside the container 9 to form a liquid mixture L3. The stirring device 5 is supported by the support base 10.

[0035] In this embodiment, the stirring device 5 includes a rod 50, a rotary motor 51 connected to the upper end of the rod 50, and a propeller 52 attached to the lower end of the rod 50.

[0036] The rotary motor 51 is installed at the uppermost stage of the front part of the support base 10 and is located above the installation base 2. A rod 50 extends downward from the rotary motor 51. The rod 50 is parallel to the vertical direction. The rod 50 is located between the discharge port of the injection pipe 33 of the main agent injection device 3 and the discharge port of the injection pipe 43 of the additive injection device 4 in the left-right direction. The propeller 52 is attached to the lower end of the rod 50 with a fixture such as a screw and is detachable from the rod 50. The propeller 52 is made of, for example, resin. Note that the propeller 52 may be made of stainless steel or aluminum.

[0037] The stirring device 5 has its driving and driving stop of the rotary motor 51 controlled by the control device 7.

[0038] 2-5. Moving device The moving device 6 relatively moves the stirring device 5 and the installation base 2 between a stirring position where the stirring device 5 is located inside the container 9 and a standby position where the stirring device 5 is located outside the container 9.

[0039] In the present embodiment, the moving device 6 is a lifting device that raises and lowers the installation base 2. The moving device 6 raises and lowers the installation base 2 in the vertical direction between a stirring position (see FIG. 3B) where the propeller 52 of the stirring device 5 is located at the bottom inside the container 9 installed on the installation base 2 and a standby position (see FIG. 3A) where the propeller 52 is located above the container 9.

[0040] The moving device 6 is formed of, for example, a guided air cylinder. The moving device 6 is installed in the middle stage of the front part of the support base 10 and is fixed to the lower surface of the installation base 2.

[0041] The moving device 6 is controlled by the control device 7 to raise and lower the installation base 2.

[0042] 2-6. Control device The control device 7 is a device that controls each of the main agent injection device 3, the additive injection device 4, the stirring device 5, and the moving device 6. The control device 7 has an operation unit 70 operated by the user on the front surface of the control device 7.

[0043] In this embodiment, the operation unit 70 includes an operation button 71 for starting operation, a stop button 72 for stopping operation, an emergency stop button 73 for completely stopping operation, a reset button 74 for resetting abnormalities, a changeover switch 75 for switching between automatic operation and manual operation, and a touch panel 76. The touch panel 76 is a touch panel for performing various settings such as the injection amount of the main agent L1, the injection amount of the additive L2, and the switching of the device driven during manual operation. The touch panel 76 also serves as a display unit for displaying the set information. On the front surface of the control device 7, a power lamp 77, an abnormality lamp 78, and a buzzer 79 are further provided.

[0044] By operating the operation unit 70, the user causes the control device 7 to start or stop the control of each of the main agent injection device 3, the additive injection device 4, the stirring device 5, and the moving device 6.

[0045] For example, by operating the touch panel 76, the user can set the injection amounts of the main agent L1 and the additive L2 to arbitrary amounts.

[0046] 2-7. Heat-insulating case The heat-insulating case 8 is a case that houses at least the installation table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5 among the components of the liquid mixing device 1. The heat-insulating case 8 has an opening 800 through which the installation table 2 is exposed.

[0047] In this embodiment, the heat-insulating case 8 houses all of the components of the liquid mixing device 1 except the heat-insulating case 8 itself (that is, the installation table 2, the main agent injection device 3, the additive injection device 4, the stirring device 5, the moving device 6, the control device 7, and the support table 10). The heat-insulating case 8 further has an opening 801 through which the operation unit 70 of the control device 7 is exposed.

[0048] The heat-insulating case 8 is formed by assembling a plurality of flat heat-insulating plates. Each of the plurality of heat-insulating plates is formed of, for example, extruded polystyrene foam.

[0049] In this embodiment, the heat insulation case 8 is in the shape of a rectangular parallelepiped box with an open bottom surface. The heat insulation case 8 is formed by assembling a front plate 80, a rear plate 81, left and right side plates 82, 83, and a top plate 84 into the shape of a rectangular parallelepiped box. The front plate 80, the rear plate 81, the left and right side plates 82, 83, and the top plate 84 are connected to each other at adjacent ends using, for example, adhesive tape. In the space surrounded by the front plate 80, the rear plate 81, the left and right side plates 82, 83, and the top plate 84, all of the components of the liquid mixing device 1 except for the heat insulation case 8 are stored.

[0050] An opening 800 is provided in the front plate 80 at a portion corresponding to the installation table 2. The vertical length of the opening 800 is set so that the installation table 2 and the container 9 installed on the installation table 2 are always exposed forward through the opening 800 regardless of the vertical position of the installation table 2.

[0051] That is, the container 9 on the installation table 2 when in the standby position and the container 9 on the installation table 2 when in the stirring position are exposed forward through the opening 800. Thereby, the state of the liquid mixture L3 in the container 9 can be confirmed from the front through the opening 800.

[0052] An opening 801 is provided in the front plate 80 at a portion corresponding to the control device 7. The vertical length and the horizontal length of the opening 801 are set so that the entire front surface of the control device 7 is exposed. The front portion of the control device 7 is fitted into the opening 801.

[0053] The front plate 80 is further provided with an opening 802 for passing at least one table 13 fixed to the support table 10. In this embodiment, two openings 802 are provided in the front plate 80.

[0054] The heat insulation case 8 of this embodiment further has an opening 85 through which the duct 110 (see FIG. 5) of the air conditioner 11 passes. In this embodiment, the opening 85 is provided in the top plate 84. The air conditioner 11 is an external air conditioner 11 installed outside the liquid mixing device 1. The air conditioner 11 is, for example, a spot cooler.

[0055] The lower ends of the front plate 80, the rear plate 81, and the left and right side plates 82, 83 each contact the installation surface such as the floor on which the liquid mixing device 1 is installed and are supported by the installation surface. The heat insulation case 8 is movable following the movement of the support base 10. Further, the heat insulation case 8 can also be disassembled into a plurality of heat insulation plates.

[0056] By covering each component of the liquid mixing device 1 with the heat insulation case 8, it is easy to keep the temperature inside the heat insulation case 8 within a predetermined temperature range, and it is possible to suppress variations in the quality of the liquid mixture L3 formed by the liquid mixing device 1.

[0057] 2-8. Support Base The support base 10 has installed thereon all of the components of the liquid mixing device 1 except for the heat insulation case 8 (that is, the installation table 2, the main agent injection device 3, the additive injection device 4, the stirring device 5, the moving device 6, and the control device 7).

[0058] In this embodiment, the support base 10 is a metal rack. In this embodiment, the support base 10 is integrally assembled from a plurality of rectangular tube-shaped members extending in the front-rear direction, a plurality of rectangular tube-shaped members extending in the left-right direction, a plurality of rectangular tube-shaped members extending in the vertical direction, and at least one plate-shaped member.

[0059] A moving member 12 that enables the support base 10 to move horizontally is attached to the support base 10. In this embodiment, the moving member 12 is a plurality of rollers attached to the bottom portion of the support base 10.

[0060] Two tables 13 are attached to a part of the support base 10. Each of the two tables 13 protrudes forward from the support base 10. Note that the table 13 may be constituted by a part of the plate-shaped member constituting the support base 10.

[0061] 2-9. Container As shown in FIGS. 3A, 3B, 4A, and 4B, the container 9 includes a container body 90 and a holding member 91 that detachably holds the container body 90. The container 9 and the above-described liquid mixing device 1 constitute a liquid mixing device unit 100.

[0062] The container body 90 is made of a transparent or translucent resin such as plastic. The container body 90 includes a cylindrical tube portion 900 having a central axis parallel to the vertical direction, a bottom portion 901 that closes the lower end of the tube portion 900, and a flange portion 902 that protrudes from the upper end portion of the tube portion 900 and is annular in plan view. A spout 903 that protrudes radially outward is provided in a part of the circumferential direction of the flange portion 902.

[0063] The holding member 91 is made of, for example, metal. The holding member 91 includes an upper frame portion 910 that is annular in plan view, a bottom frame portion 911 that is annular in plan view, a plurality of vertical frame portions 912 that connect the upper frame portion 910 and the bottom frame portion 911, and a handle portion 913 that connects the upper frame portion 910 and the bottom frame portion 911. The plurality of vertical frame portions 912 are spaced apart from each other in the circumferential direction of the upper frame portion 910.

[0064] The handle portion 913 is connected to a location different from the location where the vertical frame portions 912 are connected among the upper frame portion 910 and the bottom frame portion 911. The handle portion 913 forms a grip portion 9130 that protrudes such that the remaining portion except for the upper and lower end portions is located radially outside the upper frame portion 910 and the bottom frame portion 911.

[0065] As shown in FIG. 4B, the holding member 91 further includes an X-shaped reinforcing portion 914 fixed to the bottom frame portion 911 so as to pass through the center of the bottom frame portion 911. A positioning member 915 used for positioning with respect to the installation table 2 is attached to the central portion of the reinforcing portion 914. The positioning member 915 is a magnetic body in this embodiment, and more specifically, a magnet.

[0066] The container body 90 is detachably held by the holding member 91 by the upper portion of the tube portion 900 being supported over the circumferential direction by the upper frame portion 910 of the holding member 91 and the bottom portion 901 being supported by the reinforcing portion 914.

[0067] The user can carry the container 9 while grasping the gripping portion 9130 of the handle portion 913 of the holding member 91 with one hand.

[0068] With the container 9 placed on the installation table 2, the positioning portion 20 of the installation table 2 and the positioning member 915 are attracted to each other by magnetic force, so that the position of the container 9 on the installation table 2 is fixed. Thereby, when stirring the main agent L1 and the additive L2 injected into the container body 90 with the propeller 52 of the stirring device 5, it is possible to suppress the container 9 on the installation table 2 from being displaced.

[0069] By replacing the container body 90 of the container 9 with a new container body 90, cleaning work and the like of the container body 90 can be omitted, so that the maintainability can be improved.

[0070] 3. Method of Using the Liquid Mixing Device Unit Subsequently, an example of the method of using the liquid mixing device unit 100 described above will be described.

[0071] The liquid mixing device unit 100 is installed, for example, inside a factory. As shown in the installation example in FIG. 5, in the liquid mixing device 1, according to the temperature of the surrounding installation environment, the duct 110 of the air conditioner 11 is connected to the opening 85 of the heat insulation case 8. Thereby, it is easy to maintain the temperature inside the heat insulation case 8 at a temperature suitable for mixing the main agent L1 and the additive L2 (for example, in the range of 20°C to 25°C), and it is possible to suppress the reaction after mixing the main agent L1 and the additive L2 from accelerating.

[0072] First, the user places the container 9 on the installation table 2 exposed from the opening 800 of the heat insulation case 8 (see FIG. 3A). At this time, the installation table 2 is located at the standby position.

[0073] Next, the user operates the operation unit 70 of the control device 7. For example, the user sets the changeover switch 75 of the operation unit 70 to automatic operation and presses the operation button 71. Then, the control device 7 controls each device of the liquid mixing device 1 as follows to start automatic operation.

[0074] That is, the control device 7 controls the moving device 6 to raise the installation table 2 from the standby position to the stirring position (see FIG. 3B). With the installation table 2 in the stirring position, the propeller 52 of the stirring device 5 is arranged at the bottom portion of the container body 90 of the container 9 (specifically, at a position about 10 mm above the bottom). Also in this state, the discharge port of the injection pipe 33 of the main agent injection device 3 and the discharge port of the injection pipe 43 of the additive injection device 4 are arranged inside the upper part of the container body 90.

[0075] Next, the control device 7 controls the main agent injection device 3 and the additive injection device 4 respectively to inject the main agent L1 into the container 9 from the injection pipe 33 of the main agent injection device 3 and inject the additive L2 into the container 9 from the injection pipe 43 of the additive injection device 4. At this time, the main agent L1 and the additive L2 with the injection amounts preset by the touch panel 76 are injected into the container 9.

[0076] Next, the control device 7 controls the stirring device 5 to rotate the propeller 52 in the container 9 to stir the main agent L1 and the additive L2 in the container 9. Note that the rotation of the propeller 52 may be performed while injecting the main agent L1 and the additive L2 into the container 9 from the injection devices 3 and 4. By stirring the main agent L1 and the additive L2 by the propeller 52 of the stirring device 5 for a predetermined time, a liquid mixture L3 in which the main agent L1 and the additive L2 are mixed is formed in the container 9. When a predetermined time has elapsed since the start of the rotation of the propeller 52, the control device 7 stops the rotation of the propeller 52.

[0077] Next, the control device 7 controls the moving device 6 to lower the installation table 2 from the stirring position (see FIG. 3B) to the standby position (see FIG. 3A). As a result, the propeller 52 of the stirring device 5 is located outside the container 9 (above the container 9). The control of the automatic operation by the control device 7 ends when the installation table 2 is moved to the standby position.

[0078] Next, the user takes out the container 9 from the installation table 2 through the opening 800 of the heat insulating case 8. At this time, the user can hold the container 9 by grasping the gripping portion 9130 of the handle portion 913 of the container 9 with one hand and carry it.

[0079] In addition, in the liquid mixing device 1 of the present embodiment, when the user manually switches the changeover switch 75 of the operation unit 70 of the control device 7 and selects a device driven by the touch panel 76, only one of the main agent injection device 3 and the additive injection device 4 can be operated, or only the stirring device 5 can be operated. Thereby, it is possible to confirm whether the injection amount of the main agent L1 from the main agent injection device 3 and the injection amount of the additive L2 from the additive injection device 4 are the set injection amounts, or to confirm whether the propeller 52 of the stirring device 5 rotates.

[0080] 4. Operational effects In the liquid mixing device 1 of the present embodiment described above, by placing the container 9 on the installation table 2 through the opening 800 of the heat insulating case 8 and only operating the operation unit 70 of the control device 7 (pressing the operation button 71), the liquid mixture L3 can be formed in the container 9. And the container 9 on the installation table 2 can be taken out through the opening 800.

[0081] Since the liquid mixing device 1 of the present embodiment does not include a static mixer as in the conventional example, the static mixer and the cleaning device for cleaning the static mixer can be omitted, and the liquid mixing device 1 can be made more compact. Further, in the liquid mixing device 1 of the present embodiment, since the operations of cleaning the static mixer with the cleaning liquid and discarding the waste liquid of the cleaning liquid and the mixed liquid after cleaning are not required, the maintainability can be improved.

[0082] Also, in the liquid mixing device 1 of the present embodiment, since all of the remaining configurations of the liquid mixing device 1 except the heat insulating case 8 are covered by the heat insulating case 8, the temperature change in the heat insulating case 8 can be suppressed, and the deviation of the quality of the liquid mixture L3 can be easily suppressed.

[0083] In addition, in the liquid mixing device 1 of the present embodiment, since the installation base 2 is lifted and lowered by the moving device 6 and the propeller 52 of the stirring device 5 is not lifted and lowered, contact between the propeller 52 and the injection pipes 33, 43 of the injection devices 3, 4 can be prevented.

[0084] In addition, in the liquid mixing device 1 of the present embodiment, since all of the components of the liquid mixing device 1 except for the heat insulating case 8 are installed on the support base 10 with the moving member 12, it is easy to change the installation position of the liquid mixing device 1.

[0085] In addition, in the liquid mixing device 1 of the present embodiment, since the temperature inside the heat insulating case 8 can be adjusted by the air conditioner 11, it is easy to suppress variations in the quality of the liquid mixture L3.

[0086] In addition, in the liquid mixing device unit 100 of the present embodiment, since the container 9 is composed of the holding member 91 and the container body 90 that is detachable from the holding member 91, a disposable container body 90 can be used, and it is easy to improve maintainability.

[0087] In addition, in the liquid mixing device unit 100 of the present embodiment, since the positioning portion 20 is provided on the installation base 2 to position the container 9, displacement of the container 9 during stirring can be suppressed.

[0088] 5. Modification Subsequently, modification examples of the above-described liquid mixing device 1 and liquid mixing device unit 100 will be described. The modification examples described below can be combined as appropriate.

[0089] The moving device 6 is not limited to a lifting device that lifts and lowers the installation base 2, and may be a device that lifts and lowers the stirring device 5. Further, the stirring device 5 may incorporate the moving device 6, or the rod 50 may be lifted and lowered vertically by the moving device 6.

[0090] The control device 7 does not necessarily have the operation portion 70 on its front surface, and may be operated, for example, by a remote control that communicates wirelessly with the control device 7. In this case, the opening 801 is not required in the heat insulating case 8.

[0091] The liquid mixing device 1 does not necessarily need to include a support base 10, and each device included in the liquid mixing device 1 (specifically, the installation table 2, the main agent injection device 3, the additive injection device 4, the stirring device 5, the moving device 6, and the control device 7) may be installed on an installation surface such as the floor where the liquid mixing device 1 is installed.

[0092] Also, a moving member 12 does not necessarily need to be attached to the support base 10.

[0093] The heat insulation case 8 does not necessarily need to have an opening 85 through which a duct 110 connected to the air conditioner 11 passes. In this case, the liquid mixing device 1 may include an air conditioner installed in the heat insulation case 8. Also, depending on the installation environment, the temperature inside the heat insulation case 8 of the liquid mixing device 1 does not necessarily need to be adjusted by the air conditioner.

[0094] The container 9 is not limited to having a container body 90 and a holding member 91, and may be formed of a single member.

[0095] The installation table 2 does not necessarily need to be provided with a positioning portion 20. In this case, it is preferable that the container 9 has a weight that is less likely to cause misalignment during stirring by the stirring device 5.

[0096] The positioning portion 20 is not limited to a magnet, and may be a device that positions the holding member 91 by other methods. For example, the positioning portion 20 may be a recess into which the bottom of the holding member 91 fits.

[0097] The mounting table 2 may be provided with a weighing device for measuring the weight of the objects placed on the mounting table 2 (i.e., the container 9 and the liquid mixture L3). The data measured by the weighing device is preferably transmitted to the touch panel 76 of the control device 7 or an external management device such as a personal computer and automatically recorded. In this case, when the liquid mixture L3 is used as an adhesive for bonding the pair of metal outer skins and the core material of the sandwich panel, it is easy to manage the amount of the liquid mixture L3 used in the production of the sandwich panel. Thereby, for example, when a prototype of the sandwich panel is made at a contract manufacturing site, it is easy to track the amount of the liquid mixture L3 used in the production of the sandwich panel. Also, it is easy to set the application amount of the adhesive (liquid mixture L3) between the metal outer skin and the core material of the sandwich panel as a set amount, and it is easy to manufacture the sandwich panel in a mode corresponding to a fire resistance test. Also, since it is easy to set the application amount of the adhesive (liquid mixture L3) between the metal outer skin and the core material of the sandwich panel as a set amount, it is also easy to prevent the adhesive (liquid mixture L3) from oozing out from between the metal outer skin and the core material.

[0098] The heat insulation case 8 only needs to house at least the mounting table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5 (i.e., the portions through which the main agent L1 or the additive L2 flows) in the liquid mixing device 1, and does not need to house the moving device 6 or the control device 7.

[0099] The liquid mixture L3 formed by the liquid mixing device 1 is not limited to an adhesive, and may be a liquid mixture formed by mixing other main agents and additives such as paints.

[0100] (Summary) As in the embodiment and its modification described above, the liquid mixing device 1 of the first aspect has the following configuration.

[0101] That is, the liquid mixing device 1 of the first aspect includes an installation table 2, a main agent injection device 3, an additive injection device 4, a stirring device 5, a moving device 6, a control device 7, and a heat insulation case 8. A container 9 is detachably installed on the installation table 2. The main agent injection device 3 injects the main agent L1 into the container 9. The additive injection device 4 injects the additive L2 into the container 9. The stirring device 5 stirs the main agent L1 and the additive L2 inside the container 9. The moving device 6 relatively moves the stirring device 5 and the installation table 2 between a stirring position where the stirring device 5 is located inside the container 9 and a standby position where the stirring device 5 is located outside the container 9. The control device 7 controls the main agent injection device 3, the additive injection device 4, the stirring device 5, and the moving device 6. The heat insulation case 8 houses the installation table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5. The heat insulation case 8 has an opening 800 through which the installation table 2 is exposed.

[0102] In the liquid mixing device 1 of the first aspect having the above-described configuration, after installing the container 9 on the installation table 2 through the opening 800 of the heat insulation case 8, each device can be automatically controlled by the control device 7 as follows. That is, the stirring device 5 and the installation table 2 are relatively moved by the moving device 6, and the stirring device 5 is positioned inside the container 9. The main agent L1 and the additive L2 are injected into the container 9 by the injection devices 3 and 4. The main agent L1 and the additive L2 inside the container 9 are stirred by the stirring device 5 to form the liquid mixture L3. The stirring device 5 and the installation table 2 are relatively moved by the moving device 6, and the stirring device 5 is positioned outside the container 9. Thereby, in the liquid mixing device 1 of the first aspect, the container 9 containing the liquid mixture L3 can be taken out from the installation table 2 through the opening 800 of the heat insulation case 8. In the liquid mixing device 1 of the first aspect, since it does not include a static mixer, there is no need for a tank or a pump for storing a solvent for cleaning the static mixer, so the entire device can be made compact. Further, in the liquid mixing device 1 of the first aspect, since there is no need for an operation of cleaning the static mixer or an operation of discarding waste liquid of the liquid mixture or the solvent discharged from the static mixer, the maintainability can be improved. Further, in the liquid mixing device 1 of the first aspect, the heat insulation case 8 houses the installation table 2, the main agent injection device 3, the additive injection device 4, and the stirring device 5. Therefore, in the liquid mixing device 1 of the first aspect, the main agent L1, the additive L2, and the liquid mixture L3 are less affected by the temperature of the surrounding installation environment, and it is easy to suppress the occurrence of bias in the quality of the liquid mixture L3.

[0103] Further, as in the above-described embodiment and its modification, the liquid mixing device 1 of the second aspect additionally includes the following configuration in addition to the configuration of the first aspect.

[0104] That is, in the liquid mixing device 1 of the second aspect, the moving device 6 is a lifting device for lifting the installation table 2.

[0105] In the liquid mixing device 1 of the second aspect having the above configuration, by raising and lowering the installation table 2 by the moving device 6, the container 9 installed on the installation table 2 can be moved between the stirring position and the standby position. In the liquid mixing device 1 of the second aspect, since the movement of the stirring device 5 can be suppressed, it is possible to prevent the injection devices 3, 4, etc. and the stirring device 5 during movement from coming into contact with each other and causing problems.

[0106] Also, as in the above-described embodiment and its modification, the liquid mixing device 1 of the third aspect additionally includes the following configuration in addition to the configuration of the first or second aspect.

[0107] That is, in the liquid mixing device 1 of the third aspect, the control device 7 has an operation unit 70 operated by the user. The heat insulation case 8 houses the control device 7 and has an opening 801 through which the operation unit 70 is exposed.

[0108] In the liquid mixing device 1 of the third aspect having the above configuration, by the user operating the operation unit 70 of the control device 7 exposed from the opening 801 of the heat insulation case 8, the main agent injection device 3, the additive injection device 4, the stirring device 5, and the moving device 6 can be automatically controlled by the control device 7. Thereby, in the liquid mixing device 1 of the third aspect, the formation of the liquid mixture L3 can be easily performed.

[0109] Also, as in the above-described embodiment and its modification, the liquid mixing device 1 of the fourth aspect additionally includes the following configuration in addition to the configuration of any one of the first to third aspects.

[0110] That is, the liquid mixing device 1 of the fourth aspect further includes a support base 10 on which the installation table 2, the main agent injection device 3, the additive injection device 4, the stirring device 5, the moving device 6, and the control device 7 are installed. A moving member 12 that enables the horizontal movement of the support base 10 is attached to the support base 10.

[0111] In the liquid mixing device 1 of the fourth aspect having the above-described configuration, each component included in the liquid mixing device 1 is installed on the support base 10, and since the moving member 12 is attached to the support base 10, it is easy to move the liquid mixing device 1. Therefore, in the liquid mixing device 1 of the fourth aspect, the installation position of the liquid mixing device 1 can be easily changed.

[0112] Also, like the above-described one embodiment and its modification, the liquid mixing device 1 of the fifth aspect additionally includes the following configuration in addition to the configuration of any one of the first to fourth aspects.

[0113] That is, in the liquid mixing device 1 of the fifth aspect, the heat insulation case 8 further has an opening 85 through which the duct 110 connected to the air conditioner 11 passes.

[0114] In the liquid mixing device 1 of the fifth aspect having the above-described configuration, by connecting the heat insulation case 8 and the duct 110 of the air conditioner 11, the temperature inside the heat insulation case 8 can be adjusted by the air conditioner 11. Therefore, in the liquid mixing device 1 of the fifth aspect, it is easy to set the temperature inside the heat insulation case 8 to a temperature suitable for forming the liquid mixture L3, and it is easy to suppress variations in the quality of the liquid mixture L3.

[0115] Also, like the above-described one embodiment and its modification, the liquid mixing device unit 100 of the sixth aspect includes the liquid mixing device 1 of any one of the first to fifth aspects and a container 9 detachably installed on the installation base 2 of the liquid mixing device 1. The container 9 has a container body 90 and a holding member 91 that detachably holds the container body 90.

[0116] In the liquid mixing device unit 100 of the sixth aspect having the above-described configuration, for example, a disposable container body 90 can be combined with the holding member 91 for use, and since the cleaning work of the container body 90 can be omitted, the maintainability can be improved.

[0117] Also, like the above-described one embodiment and its modification, the liquid mixing device unit 100 of the seventh aspect additionally includes the following configuration in addition to the configuration of the sixth aspect.

[0118] That is, in the liquid mixing device unit 100 of the seventh aspect, the installation base 2 is provided with a positioning portion 20 for positioning the holding member 91.

[0119] In the liquid mixing device unit 100 of the seventh aspect having the above configuration, when the main agent L1 and the additive L2 in the container 9 are stirred by the stirring device 5, the positioning portion 20 can suppress the container 9 on the installation base 2 from being displaced.

[0120] Also, as in the above-described embodiment and its modified example, the liquid mixing device unit 100 of the eighth aspect additionally includes the following configuration in addition to the configuration of the seventh aspect.

[0121] That is, in the liquid mixing device unit 100 of the eighth aspect, a magnetic body is attached to the bottom of the holding member 91. The positioning portion 20 is a magnet attached to the installation base 2.

[0122] In the liquid mixing device unit 100 of the eighth aspect having the above configuration, since the positioning of the container 9 can be easily performed using the magnetic force of the magnet provided on the installation base 2, the container 9 can be easily attached to and detached from the installation base 2.
