Summary of the Invention
Problems to be Solved by the Invention
[0005] In the measurement system described in Patent Document 1, special equipment such as a measurement unit for measuring the shear stress acting on the workpiece is required.
[0006] The present disclosure has been made in view of the above problems, and relates to a stirring and defoaming treatment system and a stirring and defoaming treatment method capable of detecting the state of a workpiece without providing special equipment. [Means for solving the problem]
[0007] A stirring and defoaming treatment system according to one embodiment of the present disclosure is a stirring and defoaming treatment system comprising a stirring and defoaming treatment apparatus that performs stirring and defoaming treatment on a container containing a material to be treated by revolving and rotating the material to be treated, A lid that closes the opening of the container, A first temperature sensor for measuring the temperature of the object to be processed contained in the container, A second temperature sensor measures the temperature of the internal gas contained inside the container, It comprises a calculation unit, The calculation unit derives a representative shear rate acting on the workpiece based on a heat balance equation that shows the relationship between the heat accumulated in the workpiece when the stirring and defoaming treatment is performed, the heat balance between the workpiece and the internal gas, and viscosity dissipation, as well as the temperatures measured by the first and second temperature sensors.
[0008] According to the above configuration, a representative shear rate acting on the workpiece can be derived using a heat balance equation that shows the relationship between the heat accumulated in the workpiece, the heat balance between the workpiece and the internal gas, and viscosity dissipation when stirring and defoaming is performed, as well as the measurement results from a first temperature sensor that measures the temperature of the workpiece and a second temperature sensor that measures the temperature of the internal gas. In other words, a stirring and defoaming treatment system capable of detecting the state of the workpiece can be provided without requiring special equipment such as a measuring unit that measures the shear stress acting on the workpiece.
[0009] Another configuration of the stirring and defoaming treatment system according to this disclosure is that the first temperature sensor has a first detection unit that detects infrared radiation emitted from the object to be treated.
[0010] With the above configuration, the temperature of the material being processed, which is flowing inside the container due to the stirring and defoaming process, can be detected non-contact by using the first detection unit.
[0011] Another configuration of the stirring and defoaming treatment system according to this disclosure is such that the second temperature sensor has a second detection unit that comes into contact with the internal gas.
[0012] With the above configuration, the temperature of the internal gas can be accurately detected by using a second detection unit that comes into contact with the internal gas.
[0013] Another configuration of the stirring and defoaming treatment system relating to this disclosure is that the container is an insulated container having an insulating layer.
[0014] According to the above configuration, by using an insulated container, the amount of heat transferred between the object to be processed inside the insulated container and the outside of the insulated container can be reduced. In other words, in the heat balance equation, it is only necessary to consider the heat transfer inside the container, i.e., the heat balance between the object to be processed and the internal gas. As a result, by using the measurement results of the first temperature sensor that measures the temperature of the object to be processed and the measurement results of the second temperature sensor that measures the temperature of the internal gas, a sufficiently accurate representative shear rate acting on the object to be processed can be derived.
[0015] Another configuration of the stirring and defoaming treatment system according to this disclosure is that the container comprises an inner container for containing the material to be treated, and an outer container that contains the inner container without contact with the sides and bottom of the inner container, The aforementioned heat insulating layer is an air layer between the inner container and the outer container.
[0016] According to the above configuration, the container has a double-walled structure with an inner and outer container, and an air layer acting as an insulating layer is placed between them. This reduces the amount of heat transferred between the object to be processed inside the container and the outside of the container. In other words, the air layer allows for easy and effective insulation.
[0017] A stirring and defoaming treatment system according to one embodiment of the present disclosure is a stirring and defoaming treatment system comprising a stirring and defoaming treatment apparatus that performs stirring and defoaming treatment on a container containing a material to be treated by revolving and rotating the material to be treated, A lid that closes the opening of the container, A container holder that houses the aforementioned container and revolves and rotates on its axis, A first temperature sensor for measuring the temperature of the object to be processed contained in the container, A second temperature sensor measures the temperature of the internal gas contained inside the container, A third temperature sensor for measuring the temperature of the outer surface of the container or the container holder, It comprises a calculation unit, The calculation unit derives a representative shear rate acting on the workpiece based on a heat balance equation that shows the relationship between the heat accumulated in the workpiece when the stirring and defoaming treatment is performed, the heat balance between the workpiece and the internal gas, the heat balance between the workpiece and the outside of the container through the outer surface of the container or the container holder, and viscosity dissipation, as well as the temperatures measured by the first temperature sensor, the second temperature sensor, and the third temperature sensor.
[0018] According to the above configuration, the representative shear rate acting on the workpiece can be derived using a heat balance formula that defines the representative shear rate acting on the workpiece, the measurement result of a first temperature sensor that measures the temperature of the workpiece, the measurement result of a second temperature sensor that measures the temperature of the internal gas, and the measurement result of a third temperature sensor that measures the temperature of the outer surface of the container or container holder. In other words, a stirring and defoaming treatment system capable of detecting the state of the workpiece can be provided without providing special equipment such as a measuring unit that measures the shear stress acting on the workpiece.
[0019] Another configuration of the stirring and defoaming treatment system according to this disclosure is such that the third temperature sensor includes a first temperature detection unit and a second temperature detection unit, the first temperature detection unit measures the outer surface of the bottom of the container, and the second temperature detection unit measures the outer surface of the side of the container or the container holder.
[0020] With the above configuration, the amount of heat transferred between the object to be processed and the bottom of the container can be detected using the first temperature detection unit of the third temperature sensor, and the amount of heat transferred between the object to be processed and the outer surface of the side of the container or container holder can be detected using the second temperature detection unit of the third temperature sensor.
[0021] Another configuration of the stirring and defoaming treatment system according to this disclosure is that the stirring and defoaming treatment device comprises a revolving body that revolves the container, The third temperature sensor has a temperature detection unit that is fixed to the orbiting body and revolves without rotating on its axis, while detecting infrared radiation emitted from the outer surface of the container holder.
[0022] With the above configuration, the temperature detection unit of the third temperature sensor is not subjected to centrifugal force due to rotation. As a result, malfunctions and failures in the temperature detection unit become less likely.
[0023] Another configuration of the stirring and defoaming treatment system according to this disclosure is that the third temperature sensor has a temperature detection unit that is fixed to the container holder and detects infrared radiation emitted from the outer surface of the container while revolving and rotating.
[0024] With the above configuration, the temperature of the outer surface of the container holder can be detected non-contactually by using the temperature detection unit of the third temperature sensor.
[0025] A stirring and defoaming treatment method according to one embodiment of the present disclosure is a stirring and defoaming treatment method in which a container containing a workpiece is revolved and rotated to perform stirring and defoaming treatment on the workpiece, comprising: a first measurement step of measuring the temperature of the workpiece contained in the container with a first temperature sensor; a second measurement step of measuring the temperature of the internal gas contained inside the container with a second temperature sensor; and a derivation step of deriving a representative shear rate acting on the workpiece based on a heat balance equation showing the relationship between at least the heat accumulated in the workpiece when the stirring and defoaming treatment is performed, the heat balance between the workpiece and the internal gas, and viscosity dissipation, and the temperatures measured in the first measurement step and the second measurement step.
[0026] According to the above configuration, a representative shear rate acting on the workpiece can be derived using a heat balance equation that shows the relationship between the heat accumulated in the workpiece, the heat balance between the workpiece and the internal gas, and viscosity dissipation when stirring and defoaming is performed, as well as the measurement results of the first measurement step in which the temperature of the workpiece is measured and the measurement results of the second measurement step in which the temperature of the internal gas is measured. In other words, a stirring and defoaming treatment method that can detect the state of the workpiece can be provided without providing special equipment such as a measuring unit that measures the shear stress acting on the workpiece.
[0027] A stirring and defoaming treatment method according to one embodiment of the present disclosure is a stirring and defoaming treatment method in which a container containing a workpiece is revolved and rotated to perform stirring and defoaming treatment on the workpiece, comprising: a first measurement step of measuring the temperature of the workpiece contained in the container with a first temperature sensor; a second measurement step of measuring the temperature of the internal gas contained inside the container with a second temperature sensor; a third measurement step of measuring the temperature of the outer surface of the container or a container holder that contains the container and revolves and rotates with a third temperature sensor; a heat balance formula showing the relationship between at least the heat accumulated in the workpiece when the stirring and defoaming treatment is performed, the heat balance between the workpiece and the internal gas, the heat balance between the workpiece and the outside of the container through the outer surface of the container or the container holder, and viscosity dissipation; and a derivation step of deriving a representative shear rate acting on the workpiece based on the temperatures measured in the first measurement step, the second measurement step and the third measurement step.
[0028] According to the above configuration, the representative shear rate acting on the workpiece can be derived using a heat balance formula that defines the representative shear rate acting on the workpiece, the measurement results of a first measurement step that measures the temperature of the workpiece, the measurement results of a second measurement step that measures the temperature of the internal gas, and the measurement results of a third measurement step that measures the temperature of the outer surface of the container or container holder. In other words, a stirring and defoaming treatment method that can detect the state of the workpiece can be provided without providing special equipment such as a measuring unit that measures the shear stress acting on the workpiece.

[0030] <First Embodiment> The stirring and defoaming treatment system and stirring and defoaming treatment method according to the first embodiment will be described below with reference to the drawings. Figure 1 is a configuration diagram showing an example of the stirring and defoaming treatment apparatus 100. Figure 2 is a diagram showing the stirring and defoaming treatment system of the first embodiment. Figures 3 and 4 are diagrams showing examples of the structure of the container 1A(1) and its surroundings according to the first embodiment. Figure 5 is a diagram showing an example of the structure of the lid 10 that covers the opening of the container 1A.
[0031] The stirring and defoaming treatment system includes a stirring and defoaming treatment device 100 that performs stirring and defoaming treatment on a container 1A containing a material to be treated 5 by revolving and rotating the container 1A. As shown in Figure 1, the stirring and defoaming treatment device 100 includes a container 1A that contains the material to be treated 5, a container holder 106 on which the container 1A is mounted, and a drive mechanism D that rotates the container holder 106 around a rotation axis X1 and revolves the rotation axis X1. Figure 1 shows an example in which the stirring and defoaming treatment device 100 is provided with two container holders 106, but the number of container holders 106 can be changed. For example, if the stirring and defoaming treatment device 100 is provided with one container holder 106, the stirring and defoaming treatment device 100 may be equipped with a weight to balance during rotation.
[0032] The drive mechanism D of this embodiment shown in Figure 1 comprises a revolving gear 101, a rotating drum 102, a revolving shaft 103, a drive motor 104, a revolving table 105, a rotating gear 108, an intermediate gear 109, a sun gear 110, a gear 111, a gear 112, and a gear 113.
[0033] In the drive mechanism D, the rotating drum 102, which has a revolving gear 101, is rotatably supported with respect to the fixed shaft, the revolving shaft 103, via bearings. The rotational motion from the drive motor 104 is transmitted to the rotating drum 102 via the revolving gear 101, causing the rotating drum 102 to rotate around the revolving axis X2 of the revolving shaft 103. The revolving table 105, acting as a revolving body, is connected to and fixed to the rotating drum 102, and rotates together with the rotating drum 102, causing the container 1A mounted on the container holder 106 to revolve. The container holder 106 is rotatably supported with respect to the revolving table 105 around its axis of rotation X1. Therefore, the container holder 106 rotates, i.e., revolves, around the revolving axis X2 of the revolving shaft 103 due to the rotation of the revolving table 105.
[0034] The container holder 106 is connected to the rotating gear 108 so as to rotate together with it. The rotating gear 108 meshes with an intermediate gear 109, which is rotatably supported on the orbital table 105 via bearings. The intermediate gear 109 meshes with a sun gear 110. The sun gear 110 is located outside the rotating drum 102 and is rotatably supported relative to the rotating drum 102 via bearings.
[0035] The sun gear 110 meshes with gear 111. The braking force of a braking device 114, such as a powder brake, is transmitted to gear 111 via gears 112 and 113, which mesh with each other.
[0036] The sun gear 110 rotates in accordance with the rotating drum 102 when there is no braking force applied by the braking device 114, that is, when the braking force is 0.
[0037] When the braking force of the braking device 114 is transmitted to the sun gear 110 via the gear 111, the rotational speed of the sun gear 110 decreases compared to the rotational speed of the rotating drum 102, creating a difference between the rotational speed of the sun gear 110 and the rotational speed of the orbital table 105 connected to the rotating drum 102. As a result, the intermediate gear 109 rotates relative to the sun gear 110. Since the intermediate gear 109 meshes with the rotating gear 108, the rotating gear 108 rotates, and the container holder 106 rotates around the rotation axis X1, i.e., rotates on its own axis.
[0038] The above-described stirring and defoaming apparatus 100 is an example configuration in which the container holder 106 is revolved and rotated by a single drive motor 104, but the configuration of the stirring and defoaming apparatus 100 is not limited to the example in Figure 1. For example, instead of using a braking device 114, the stirring and defoaming apparatus 100 may be configured to have separate drive motors for revolving and rotating the container holder 106, or other configurations may be used. When separate drive motors are provided for revolving and rotating, rotation can be driven independently of revolving. The rotation drive motor may be fixed to the revolving body (e.g., revolving table 105) or may be provided separately from the revolving body. Whether a braking device 114 is used or separate drive motors for revolving and rotating are used, the rotational speed of the container 1A of the stirring and defoaming apparatus 100 and the rotational speed of revolving can be set as appropriate.
[0039] The stirring and defoaming treatment system comprises a stirring and defoaming treatment device 100, a lid 10 that closes the opening of the container 1A, a container holder 106 that houses the container 1A and revolves and rotates, a first temperature sensor 2, a second temperature sensor 3, a third temperature sensor 4, and a control unit 6. In addition, the stirring and defoaming treatment system of this embodiment comprises an input receiving unit 8, an information output unit 9, and a storage unit 7.
[0040] The control unit 6 controls the operation of the stirring and defoaming apparatus 100. In addition, the control unit 6 has a calculation processing function, i.e., the function of the calculation unit 6a of this disclosure. In the figure, the control unit 6 is shown outside the stirring and defoaming apparatus 100, but the control unit 6 may be installed inside the stirring and defoaming apparatus 100.
[0041] The memory unit 7 stores information handled by the stirring and defoaming treatment system.
[0042] The input receiving unit 8 is implemented using various switches and buttons. The input receiving unit 8 may also be various switches and buttons mounted on the stirring and defoaming processing device 100.
[0043] The information output unit 9 can be implemented using a display unit capable of displaying text information, image information, etc., or a lamp capable of displaying information by turning the light on and off. The information output unit 9 may also be a display unit or lamp mounted on the stirring and defoaming apparatus 100. Alternatively, the information output unit 9 may output information to another device that is connected in a way that enables information communication.
[0044] If the control unit 6 is located in a separate device from the stirring and defoaming apparatus 100, the control unit 6 can be implemented using, for example, a computer device. In that case, the computer device may include information calculation processing functions (calculation unit 6a), information input / output functions (input receiving unit 8, information output unit 9), information storage functions (storage unit 7), and so on.
[0045] The lid 10 may include an inner lid and an outer lid, and an internal space may be formed between the inner lid and the outer lid when the inner lid and the outer lid are combined. Alternatively, the lid 10 may be a single, integrally formed lid without an internal space. If the lid 10 has an internal space, the inner lid of the lid 10 may have one or more openings that lead from one internal space of the container 1A to the other internal space of the container 1A.
[0046] The first temperature sensor 2 measures the temperature of the object to be processed 5 contained in the container 1A (first temperature measurement step). As shown in Figure 3, the first temperature sensor 2 has a first detection unit 12 provided in either the internal space of the container 1A or the lid 10, or extending from the internal space of the container 1A to the internal space of the lid 10. Specifically, the first detection unit 12 can detect infrared radiation emitted from the object to be processed 5 contained in the container 1A. The first detection unit 12 may be provided on the lower surface of the lid 10 (the surface facing the internal space of the container 1A), or it may be provided in the internal space of the lid 10 such that the infrared light receiving unit 12a faces the opening of the inner lid of the lid 10. The first temperature sensor 2 can convert the signal output from the first detection unit 12 to calculate the temperature and transmit the calculated temperature to the control unit 6. Alternatively, the signal output from the first detection unit 12 of the first temperature sensor 2, i.e., the signal corresponding to the temperature of the object to be processed 5, may be transmitted to the calculation unit 6a, and the calculation unit 6a may convert the signal to determine the temperature.
[0047] The second temperature sensor 3 measures the temperature of the internal gas 11 contained inside the container 1A (second temperature measurement step). As shown in Figure 3, the second temperature sensor 3 may have a second detection unit 13 that is in contact with the internal gas 11. For example, the second detection unit 13 has a thermocouple provided in the internal space of the container 1A. In the example shown in Figure 5, the tips of the two metal wires 13a and 13b that constitute the thermocouple and the contact point 13c of these metal wires 13a and 13b are covered with a resin film 13d such as polyimide. The film 13d may be fixed by a pair of clamps 14 fixed to the inner surface of the lid 10. As a result, the effect of centrifugal force on the film 13d when the container 1A and lid 10 rotate and revolve can be reduced. The second temperature sensor 3 may have, for example, a main body connected to the thermocouple. The main body may be provided in the internal space of the lid 10 and connected to the thermocouple through an opening in the inner lid of the lid 10. The main unit can calculate the temperature from the thermocouple detection result and transmit the calculated temperature to the calculation unit 6a. Alternatively, the main unit may transmit a signal corresponding to the temperature of the internal gas 11 to the calculation unit 6a, and the calculation unit 6a may convert that signal to determine the temperature.
[0048] The first detection unit 12 is positioned on the axis of rotation. The second detection unit 13 is positioned near the axis of rotation. In other words, because the second detection unit 13 is positioned near the axis of rotation, the centrifugal force of rotation acting on the second detection unit 13 is reduced. Therefore, malfunctions and failures are less likely to occur in the second detection unit 13.
[0049] The third temperature sensor 4 measures the temperature of the outer surface of the container 1A or the container holder 106 (third temperature measurement step). The third temperature sensor 4 includes a first temperature detection unit 16 and a second temperature detection unit 15. The first temperature detection unit 16 measures the outer surface of the bottom of the container 1A, and the second temperature detection unit 15 measures the outer surface of the side of the container 1A or the container holder 106.
[0050] The first temperature detection unit 16 contacts the bottom surface of the container 1A to measure the temperature of the container 1A. The first temperature detection unit 16 is fixed to the container holder 106 and installed in a part that revolves and rotates together with the container 1A. For example, a space centered on the rotation axis X1 is provided at the bottom of the container holder 106, and the first temperature detection unit 16 is arranged inside this space. The first temperature detection unit 16 can be realized using, for example, the thermocouple shown in Figure 5. In that case, the first temperature detection unit 16 is installed so that the aforementioned film 13d is in contact with the bottom surface of the container 1A.
[0051] The second temperature detection unit 15 detects infrared radiation emitted from the side of the container 1A. The second temperature detection unit 15 is fixed to the orbital table 105 and, while orbiting without rotating on its own axis, detects infrared radiation emitted from the outer surface of the container holder 106.
[0052] Figure 3 shows the case where the second temperature detection unit 15 is positioned closer to the orbital axis X2 as viewed from the container 1A. Figure 4 shows the case where the second temperature detection unit 15 is positioned further away from the orbital axis X2 as viewed from the container 1A. The closer the second temperature detection unit 15 is positioned to the orbital axis X2, the smaller the centrifugal force due to the orbit acting on the second temperature detection unit 15. Although not shown in the figures, the second temperature detection unit 15 may be provided on both the side closer to the orbital axis X2 as viewed from the container 1A and the side further away from the orbital axis X2 as viewed from the container 1A. Although not shown in Figures 3 and 4, due to the rotation of the container 1A, a thin film of the material to be processed 5 is formed on the side of the container 1A closer to the orbital axis X2. The second temperature detection unit 15 on the side closer to the orbital axis X2 as viewed from the container 1A detects the heat transmitted from this thin film to the side of the container 1A.
[0053] The third temperature sensor 4 can convert the signals output from the first temperature detection unit 16 and the second temperature detection unit 15 to calculate the temperature and transmit the calculated temperature to the calculation unit 6a. Alternatively, the signals output from the first temperature detection unit 16 and the second temperature detection unit 15 of the third temperature sensor 4, i.e., signals corresponding to the outer surface of the container holder 106 and the bottom surface of the container 1A, may be transmitted to the calculation unit 6a, and the calculation unit 6a may convert these signals to determine the temperature.
[0054] The calculation unit 6a then derives a representative shear rate acting on the workpiece 5 based on a heat balance equation showing the relationship between the heat accumulated in the workpiece 5 when the stirring and defoaming process is performed, the heat balance between the workpiece 5 and the internal gas 11, the heat balance between the workpiece 5 and the outside of the container 1A through the outer surface of the container 1A or container holder 106, and viscosity dissipation, as well as the temperatures measured by the first temperature sensor 2, the second temperature sensor 3, and the third temperature sensor 4 (derivation step). Viscous dissipation corresponds to the heat generated due to viscosity (i.e., friction at the molecular level). In this embodiment, the workpiece 5 is assumed to be a material that does not generate heat or endothermic heat due to chemical reactions during the stirring and defoaming process.
[0055] As described above, the stirring and defoaming treatment method of this embodiment includes a first measurement step of measuring the temperature of the workpiece 5 contained in the container 1A with a first temperature sensor 2, a second measurement step of measuring the temperature of the internal gas 11 contained inside the container 1A with a second temperature sensor 3, a third measurement step of measuring the temperature of the outer surface of the container 1A or the container holder 106 that contains the container 1A and revolves and rotates with a third temperature sensor 4, and a derivation step of deriving a representative shear rate acting on the workpiece 5 based on a heat balance equation showing the relationship between the heat accumulated in the workpiece 5 when the stirring and defoaming treatment is performed, the heat balance between the workpiece 5 and the internal gas 11, the heat balance between the workpiece 5 and the outside of the container through the outer surface of the container 1 or the container holder 106, and viscosity dissipation, and the temperatures measured in the first measurement step, the second measurement step and the third measurement step. For example, a program for executing each step of the above stirring and defoaming treatment method is stored in the storage unit 7 in advance, and the stirring and defoaming treatment method is carried out when that program is executed.
[0056] The following describes a method for deriving the representative shear rate acting on the workpiece 5 based on the heat balance equation and the temperatures measured by the first temperature sensor 2, the second temperature sensor 3, and the third temperature sensor 4.
[0057] Figure 6 shows a model of the heat balance at each contact interface of the object to be processed 5. As shown in the figure, the container 1 is held in a container holder 106. The heat transfer between the object to be processed 5 and the internal gas 11, the heat transfer between the object to be processed 5 and the side surface of the outer surface of the container 1, and the heat transfer between the object to be processed 5 and the bottom surface of the outer surface of the container 1 are considered. The heat transfer between the object to be processed 5 and the side surface of the container 1 is estimated based on the temperature detected by a third detection unit provided on the outer surface of the metal container holder 106.
[0058] The heat balance equation is represented by the following equation (1). The left side of equation (1) represents the heat accumulation in the object to be processed 5, the first term on the right side represents the heat transfer between the object to be processed 5, the internal gas 11, and the outer surface of the container 1 (or the container holder 106), and the second term on the right side represents the viscous dissipation of the object to be processed 5. The heat transfer between the object to be processed 5, the internal gas 11, and the outer surface of the container 1, which is indicated by the first term on the right side, is shown in equation (2).

[0086] Then, the temperature T measured by the first temperature sensor 2, and the temperature T measured by the second temperature sensor 3 a , the temperature T measured by the third temperature sensor 4 s , T b The following measurements are taken continuously over time. In addition, the amount of liquid in the object being treated 5 and the maximum liquid level are used to determine the heat transfer area A of each object. a , A s , A b The following is derived: Considering the thickness and thermal conductivity of container 1 and the thickness and thermal conductivity of container holder 106, the overall heat transfer coefficient U a , U s , U b The following is derived. For example, the operator of the stirring and defoaming treatment system may use the input receiving unit 8 to pre-determine A a , A s , A b , U a , U s , U b Each of the numerical values can be input and stored in the memory unit 7. Then, the calculation unit 6a calculates the measured T, T a , T s , T b Based on each of the numerical values, the above information stored in the memory unit 7, and equations (1) and (2), the representative shear rate γ dot is determined. The calculation unit 6a may, for example, store the representative shear rate γ dot derived in this way in the memory unit 7, output it from the information output unit 9, or use it in other calculation processes.
[0087] As described above, the stirring and defoaming treatment system of this embodiment can derive a representative shear rate of the workpiece 5 using a heat balance equation that shows the relationship between the heat accumulated in the workpiece 5 when stirring and defoaming is performed, the heat balance between the workpiece 5 and the internal gas 11, the heat balance between the workpiece 5 and the outside of the container through the outer surface of the container 1A or container holder 106, and viscosity dissipation, as well as the measurement results of the first temperature sensor 2 that measures the temperature of the workpiece 5, the measurement results of the second temperature sensor 3 that measures the temperature of the internal gas 11, and the measurement results of the third temperature sensor 4 that measures the temperature of the outer surface of the container 1A or container holder 106.
[0088] <Second Embodiment> The stirring and defoaming treatment system of the second embodiment differs from the above embodiment in the configuration of the container 1. The stirring and defoaming treatment system of the second embodiment will be described below, but the same configuration as in the above embodiment will not be described.
[0089] Figure 11 shows a stirring and defoaming treatment system of the second embodiment. Figure 12 shows an example of the structure of a container 1B(1) of the second embodiment. The stirring and defoaming treatment system comprises a stirring and defoaming treatment device 100, a lid 10 that closes the opening of the container 1B, a first temperature sensor 2, a second temperature sensor 3, and a control unit 6. The control unit 6 has a calculation processing function, that is, the function of the calculation unit 6a of this disclosure. In addition, the stirring and defoaming treatment system of this embodiment comprises an input receiving unit 8, an information output unit 9, and a storage unit 7. The first temperature sensor 2 measures the temperature of the object to be processed 5 contained in the container 1B (first temperature measurement step), and the second temperature sensor 3 measures the temperature of the internal gas 11 contained inside the container 1B (second temperature measurement step).
[0090] Container 1B is an insulated container having an insulating layer 1c. For example, container 1B has an inner container 1a for containing the object to be processed 5, an outer container 1b that contains the inner container 1a without contact to the sides and bottom of the inner container 1a, and an insulating layer 1c provided between the inner container 1a and the outer container 1b. This insulating layer 1c is, for example, an air layer. Alternatively, the insulating layer 1c may be, for example, a depressurized layer or a layer filled with insulating material. With this configuration, heat is not easily transferred between the inside and outside of container 1B. In other words, the heat from the object to be processed 5 is transferred to the internal gas 11 of container 1B, but it can be assumed that it is hardly transferred to the outside of container 1B. Therefore, in this embodiment, a third temperature sensor 4 for measuring the temperature of the outer surface of container 1B or container holder 106 is not provided.
[0091] The inner container 1a and outer container 1b of container 1B may be integrally formed or may be separate and assembled when in use. Container 1B may have a spacer member 17 provided between the inner container 1a and the outer container 1b. In this case, the portion between the inner container 1a and the outer container 1b where the spacer member 17 does not exist is a space, i.e., an air layer. The lid 10 is structured to support both the inner container 1a and the outer container 1b from above. The lid 10 may suspend and support the inner container 1a so that the sides and bottom of the inner container 1a do not come into contact with the outer container 1b without the spacer member 17. The relationship between the inner container 1a and the outer container 1b can be changed as appropriate. For example, a flange may be provided on the outside of the opening of the inner container 1a, and the flange may engage with the outer container 1b so that the inner container 1a is supported by the outer container 1b. Alternatively, the outer container 1b may have a flange on the inside of its opening, and this flange may engage with the inner container 1a to support it. Or, both the inner container 1a and the outer container 1b may have flanges, and these flanges may engage with and support the inner container 1a.
[0092] The calculation unit 6a derives a representative shear rate acting on the workpiece 5 based on the heat accumulated in the workpiece 5 when stirring and defoaming is performed, the heat balance equation showing the relationship between the workpiece 5 and the internal gas 11, and viscosity dissipation, and the temperatures measured by the first temperature sensor 2 and the second temperature sensor 3 (derivation step). The calculation unit 6a may, for example, store the representative shear rate γ dot derived in this way in the storage unit 7, output it from the information output unit 9, or use it for other calculation processes.
[0093] As described above, the stirring and defoaming treatment method of this embodiment includes a first measurement step of measuring the temperature of the object to be treated 5 contained in the container 1 with a first temperature sensor 2, a second measurement step of measuring the temperature of the internal gas 11 contained inside the container 1 with a second temperature sensor 3, and a derivation step of deriving a representative shear rate acting on the object to be treated 5 based on a heat balance equation showing the relationship between the heat accumulated in the object to be treated 5 when the stirring and defoaming treatment is performed, the heat balance between the object to be treated 5 and the internal gas 11, and viscosity dissipation, and the temperatures measured in the first and second measurement steps. For example, a program for executing each step of the stirring and defoaming treatment method is stored in advance in the storage unit 7, and the stirring and defoaming treatment method is carried out by executing that program.
[0094] The following describes a method for deriving the representative shear rate acting on the workpiece 5 based on the heat balance equation and the temperatures measured by the first temperature sensor 2 and the second temperature sensor 3.
[0095] First, since it can be assumed that the heat from the object to be processed 5 is hardly transferred to the outside of the container 1B, in equation (2) described in the above embodiment, the second term on the right side represents the heat transfer between the object to be processed 5 and the side surface of the outer surface of the container 1B, as described in "U s A s (T s -T)」 and the third term on the right side, "U" which represents the heat transfer between the object to be processed 5 and the bottom surface of the outer surface of container 1B. b A b (T b In this embodiment, -T) is considered to be zero. Therefore, the following equation (20) holds.
[0096]
number
[0097] Figure 13 is a graph showing the temporal changes in the temperature of the workpiece 5 measured by the first temperature sensor 2 and the temperature of the internal gas 11 measured by the second temperature sensor 3 during the stirring and defoaming process. Figure 14 is a graph showing the temporal changes in the "heat accumulation term in the workpiece 5 (i.e., liquid phase accumulation term)", "heat transfer term between the workpiece 5 and the internal gas 11 (i.e., gas-liquid heat transfer term)", "viscous dissipation term of the workpiece 5", and "representative shear rate" of equation (20), derived based on these measurement results. Note that on the vertical axis of Figure 14, the "heat accumulation term in the workpiece 5 (i.e., liquid phase accumulation term)", "heat transfer term between the workpiece 5 and the internal gas 11 (i.e., gas-liquid heat transfer term)", and "viscous dissipation term of the workpiece 5" are labeled as heat flux.
[0098] As shown in Figure 13, during the stirring and defoaming process, the temperature of the material being treated 5 and the internal gas 11 gradually increases over time. Also, as shown in Figure 14, the representative shear rate remains almost constant regardless of the passage of time.
[0099] Next, Figure 15 shows the relationship between the orbital velocity and the representative shear rate. The stirring and defoaming treatment apparatus 100 used was the apparatus sold by Shashin Kagaku Co., Ltd. under the name SK-300SII, and the apparatus sold by Shashin Kagaku Co., Ltd. under the name SK-400TR. The SK-300SII has an orbital radius R of 0.058 (m), and the SK-400TR has an orbital radius R of 0.087 (m). The material to be treated 5 is silicone oil, with a liquid volume of 50 (mL) and viscosity η of 3 (Pa·s) and 30 (Pa·s). The orbital velocity is 1000 (rpm) to 2000 (rpm). The orbital-rotation velocity ratio calculated as rotational velocity / orbital velocity is 0.4.
[0100] As shown in Fig. 15, for any viscosity and revolution radius, a relationship in which the representative shear rate is proportional to the revolution speed was observed. When the viscosity was low, the influence of the revolution radius was not seen in the relationship between the representative shear rate and the revolution speed, and the line passed through the origin. That is, it can be seen that a flow corresponding to the revolution speed was caused. However, when the viscosity increased, it was predicted that the representative shear rate would be larger for a larger revolution radius, and the shear rate would be substantially zero when the revolution speed was small. Actually, at this time, it was confirmed by observation that the object to be processed 5 was rotating solidly in the container 1B.
[0101] Next, in the same stirring method, it was considered that the centrifugal force and the viscous force govern the flow state, and a dimensionless number Ut, which is the ratio of the sum of the centrifugal forces caused by rotation and revolution to the viscous force acting on the inner wall of the rotating container 1B, was defined by the following formula (21), and an attempt was made to systematically understand the relationship between the viscosity, revolution radius, revolution speed, rotation radius, revolution-rotation speed ratio of the object to be processed 5 and the flow state. That is, Ut = centrifugal force / viscous force.
[0102]
Equation
[0103] Here, ω is the revolution angular velocity (rad / s), α is the revolution-rotation speed ratio, r and R are the rotation radius (m) and the revolution radius (m), m is the mass (kg) of the object to be processed 5, A s is the heat transfer area (m 2 ) between the object to be processed 5 and the container side surface during stirring and defoaming treatment, and it is considered that the shear stress acts here. Also, it was considered that the representative shear rate is proportional to the rotation speed, and a dimensionless shear rate γ̃ was defined by the following formula (22).
[0104]
Equation
[0105] Figure 16 shows the relationship between the dimensionless shear rate γ (dot tilda) and Ut. Specifically, it shows the relationship between the dimensionless shear rate γ (dot tilda) and Ut obtained from measurements taken under various conditions, such as when the material to be treated 5 is a silicone oil with viscosities of 1 (Pa·s), 3 (Pa·s), 10 (Pa·s), 13 (Pa·s), 30 (Pa·s), 100 (Pa·s), and 300 (Pa·s); when the material to be treated 5 is an epoxy resin; when the stirring and defoaming apparatus 100 used for stirring and defoaming is the SK-300SII mentioned above; when the stirring and defoaming apparatus 100 used for stirring and defoaming is the SK-400TR mentioned above; when the rotational speed ratio is 1; when the rotational speed ratio is 0.8; and when the rotational speed ratio is 0.6.
[0106] As shown in the figure, the dimensionless shear rate is a function of Ut, and it was found that it can be classified into three regions based on its dependence on Ut. Specifically, in region I, where Ut < 5, a viscous force greater than the centrifugal force acts on the workpiece 5, so increasing the centrifugal force can significantly increase the dimensionless shear rate. On the other hand, in region III, where Ut ≥ 70, a centrifugal force greater than the viscous force acts on the workpiece 5, and an increase in the dimensionless shear rate cannot be expected by increasing the centrifugal force. In region II, which lies between these two regions, the dependence of Ut on the dimensionless shear rate is smaller than in region I, and it is considered an intermediate region.
[0107] As described above, the stirring and defoaming treatment system of this embodiment can derive a representative shear rate of the workpiece 5 by using a heat balance equation that shows the relationship between the heat accumulated in the workpiece 5 when stirring and defoaming is performed, the heat balance between the workpiece 5 and the internal gas 11, and viscosity dissipation, as well as the measurement results of the first temperature sensor 2 that measures the temperature of the workpiece 5 and the measurement results of the second temperature sensor 3 that measures the temperature of the internal gas 11.
[0108] <Third Embodiment> The structure of the container 1 in the third embodiment differs from that of the above embodiment. The stirring and defoaming treatment system of the third embodiment will be described below, but the same configuration as in the above embodiment will not be described.
[0109] Figure 17 shows the structure of the container 1C(1) and its surroundings according to the third embodiment.
[0110] In this embodiment, the second temperature detection unit 15 of the third temperature sensor 4 is provided on the inner surface side of the container holder 106 (i.e., the side facing the container 1C). In this case, the second temperature detection unit 15 of the third temperature sensor 4 is a temperature detection unit that is fixed to the container holder 106 and detects infrared radiation emitted from the outer surface of the container 1C while revolving and rotating. In addition, the first temperature detection unit 16 of the third temperature sensor 4 is located in a space provided at the bottom of the container holder 106. In this case, the first temperature detection unit 16 of the third temperature sensor 4 is a temperature detection unit that is fixed to the container holder 106 and detects infrared radiation emitted from the outer surface of the container 1C while revolving and rotating.

For example, the configuration of the stirring and defoaming treatment device 100 and the configuration of the container 1 can be changed as appropriate.
[0112] <2> In the above embodiment, the workpiece 5 is not limited to the materials described above, and various materials can be used. Furthermore, although the above embodiment describes a case where the material to be treated 5 is a material that does not generate heat or endothermic reactions due to chemical reactions during the stirring and defoaming process, a material to be treated 5 that generates heat and endothermic reactions due to chemical reactions may also be used. In that case, the heat balance equation described above should take into account the heat and endothermic reactions of the material to be treated 5 due to chemical reactions during the stirring and defoaming process.
[0113] <3> In the above embodiment, we have described cases where the first temperature sensor 2, the second temperature sensor 3, and the third temperature sensor 4 are of a type that measures the temperature by contacting the object to be measured (e.g., a thermocouple) or of a type that measures the temperature without contacting the object to be measured (e.g., a type that detects emitted infrared rays). However, the type of temperature detection unit used can be changed as appropriate.
[0114] Furthermore, the configurations disclosed in the above embodiments (including other embodiments, the same applies hereinafter) can be applied in combination with configurations disclosed in other embodiments, provided that no inconsistencies arise. Moreover, the embodiments disclosed herein are illustrative, and the embodiments of this disclosure are not limited thereto and can be modified as appropriate without departing from the purpose of this disclosure.
