  The stirring and defoaming device 1 includes a rotating body 10 as shown in FIGS. The rotating body 10 is configured to be rotatable around a predetermined rotation axis. In the present embodiment, as shown in FIG. 1, the rotating body 10 is configured to be rotatable around a virtual straight line (revolution axis L <b> 1) that extends vertically. However, the rotating body 10 can also be configured to rotate with a straight line extending in the horizontal direction as an axis (not shown). In the present embodiment, the rotator 10 includes a bottom plate 12, a horizontal plate 14 and an upper plate 16 fixed to the bottom plate 12 (see FIGS. 2 and 3).

  The stirring and defoaming apparatus 1 includes a bearing case 20 as shown in FIGS. The bearing case 20 plays a role of holding a bearing 30 described later (see FIG. 4B). In the present embodiment, the bearing case 20 has an internal space 20S, and the bearing 30 is disposed in the internal space 20S. That is, in the present embodiment, the internal space 20 </ b> S of the bearing case 20 is a space for holding the bearing 30. The bearing case 20 is disposed at a position spaced apart from the revolution axis L <b> 1 by a predetermined distance and is fixed to the rotating body 10. As a result, the bearing case 20 revolves around the revolution axis L <b> 1 as the rotating body 10 rotates. In the stirring and defoaming device 1, the bearing case 20 is fixed to the horizontal plate 14 of the rotating body 10. Moreover, in the stirring and defoaming device 1, as shown in FIGS. 1 and 4B, the bearing case 20 is attached to the rotating body 10 so that the rotation axis of the bearing 30 intersects the revolution axis L1. ing. The bearing case 20 can be configured to be detachable from the rotating body 10.

  A through hole 22 is formed in the bearing case 20 (see FIGS. 4A and 5).

In the stirring and defoaming device 1, the internal space 20 </ b> S of the bearing case 20 and the internal space 40 </ b> S of the tubular member 40 described later communicate with each other through the through hole 22.

  The stirring and defoaming device 1 has two bearing cases 20. The two bearing cases 20 are arranged so as to be point-symmetric about the rotation axis (revolution axis L1) of the rotating body 10. However, the stirring and defoaming device may have a configuration in which three or more bearing cases 20 are attached to one rotating body 10 (not shown).

  The stirring deaerator 1 has a seal member 28 as shown in FIG. The seal member 28 plays a role of preventing a later-described lubricating liquid L from being discharged from the internal space 20 </ b> S of the bearing case 20. In the present embodiment, the seal member 28 is provided between the container holder 50 and the upper end opening of the bearing case 20. However, as a modification, the stirring and defoaming device can be configured not to have a seal member (not shown). Even when the seal member is not provided, it is possible to prevent the lubricating liquid L from being discharged by devising the shape of the bearing holder and utilizing the action of centrifugal force.

  The stirring and defoaming device 1 has a bearing 30 as shown in FIG. The bearing 30 is held by the bearing case 20 and plays a role of rotatably supporting a container holder 50 described later with respect to the rotating body 10 (bearing case 20). Specifically, in the stirring and defoaming device 1, the outer ring 32 of the bearing 30 is fixed to the bearing case 20. Further, the inner ring 34 of the bearing 30 is fixed to the rotation shaft 52 of the container holder 50. Thereby, the container holder 50 is supported so that rotation (autorotation) is possible with respect to the rotary body 10.

  The stirring and defoaming device 1 has a hollow tubular member 40 as shown in FIGS. As shown in FIG. 3, the tubular member 40 has a shape extending along a circumference C around the rotation axis (revolution axis L <b> 1) of the rotating body 10 in a plan view, and the outer shape thereof is an arc shape. It has become. Moreover, in the stirring deaerator 1, the tubular member 40 is disposed on a virtual plane orthogonal to the revolution axis L <b> 1 (see FIG. 1).

  In the stirring deaerator 1, the tubular member 40 is hollow, and the internal space 40 </ b> S is configured to communicate with the internal space 20 </ b> S of the bearing case 20 as illustrated in FIG. In the present embodiment, the through hole 22 is formed in the bearing case 20 at a position intersecting the circumference C, and the internal space 20S of the bearing case 20 and the internal space 40S of the tubular member 40 are defined as through holes. 22 (see FIG. 4A).

  In the present embodiment, the stirring and defoaming device 1 has two tubular members 40 as shown in FIGS. One end of each of the two tubular members 40 is fixed to one bearing case 20, and the other end is fixed to the other bearing case 20. The two tubular members 40 are configured such that the internal spaces 40S communicate with the internal spaces 20S of the two bearing cases 20 (see FIG. 4A).

  In the present embodiment, the constituent material of the tubular member 40 is not particularly limited. The tubular member 40 can be made of a metal such as aluminum. In the present embodiment, the tubular member 40 can be configured to be detachable from the bearing case 20. Moreover, in this Embodiment, the tubular member 40 is comprised so that the cross section cut | disconnected by the virtual plane orthogonal to the circumference C may become circular. However, the tubular member 40 can also be configured such that the cross-section is rectangular or elliptical (not shown). Alternatively, the tubular member 40 may have a configuration in which a heat sink is attached to the outer periphery (not shown).

  In the present embodiment, the bearing case 20 and the tubular member 40 are configured to be able to enclose a given fluid therein. The nature of the fluid (sealed fluid) sealed in the bearing case 20 and the tubular member 40 is not particularly limited, but a fluid that can freely flow in the internal space 20S and the internal space 40S is selected. It is preferable to do. In the stirring and defoaming apparatus 1, the lubricating liquid L of the bearing 30 can be used as the sealed fluid (see FIG. 4B). As the lubricating liquid L, any known liquid such as lubricating oil or pure water can be used. However, as a modification, the stirring and defoaming device 1 can be operated in a state where no liquid is sealed in the bearing case 20 and the tubular member 40. In the present embodiment, the sealed fluid is filled in the internal space 20S and the internal space 40S. In other words, in the present embodiment, air (bubbles) does not enter the internal space 20S and the internal space 40S (that is, the volume of the internal space 20S and the internal space 40S is equal to the volume of the sealed fluid). Ii) The sealed fluid is sealed. However, as a modification, the sealed fluid is sealed so that air exists in the internal space 20S and the internal space 40S (that is, the volume of the sealed fluid is smaller than the volume of the internal space 20S and the internal space 40S). It is also possible to do.

  The stirring and defoaming device 1 has a container holder 50 as shown in FIGS. The container holder 50 serves to hold the storage container 100. In the present embodiment, the container holder 50 is held by the bearing 30. Specifically, the container holder 50 has a rotation shaft 52, and the rotation shaft 52 is held by the bearing 30. Accordingly, the container holder 50 can rotate (spin) with respect to the rotating body 10 around a virtual straight line (spinning axis L2) passing through a predetermined position of the rotating body 10. In the present embodiment, the revolution axis L1 and the rotation axis L2 are straight lines that obliquely intersect at a predetermined angle. More specifically, the stirring deaerator 1 is configured such that the revolution axis L1 and the rotation axis L2 intersect at an angle of 45 degrees. However, as a modification, the stirring deaerator can be configured so that the revolution axis L1 and the rotation axis L2 are parallel to each other (not shown).

  As shown in FIG. 5, the stirring and deaerator 1 includes a drive mechanism 60. The drive mechanism 60 is configured to be able to rotate while revolving the container holder 50 (storage container 100). Hereinafter, an example of the drive mechanism 60 will be described with reference to FIG. FIG. 5 is a diagram for explaining the drive mechanism 60.

  The drive mechanism 60 has a central shaft 62. The central shaft 62 is a rod-shaped member configured to be rotatable with respect to the support substrate 80. In the present embodiment, the center shaft 62 is inserted through a support member 82 fixed to the support substrate 80 and attached to the support member 82 via a bearing (not shown). As a result, the central shaft 62 can rotate with respect to the support substrate 80. In addition, the rotary body 10 mentioned above is attached to the center axis | shaft 62 via a bearing. As a result, the rotating body 10 can be rotated concentrically with the central shaft 62 at a rotational speed different from that of the central shaft 62. In other words, the above-described revolution axis L <b> 1 coincides with the rotation axis of the center axis 62.

  The drive mechanism 60 has a pulley 64. The pulley 64 is attached to the central shaft 62 via a bearing (not shown). As a result, the pulley 64 can be rotated concentrically with the central shaft 62 at a rotational speed different from that of the central shaft 62. The pulley 64 is fixed to the rotating body 10 (bottom plate 12) and rotates at the same rotational speed as the rotating body 10.

  The drive mechanism 60 includes a motor 66 that rotates the pulley 64. In the stirring and defoaming device 1, when the pulley 64 rotates, the rotating body 10 rotates and the container holder 50 revolves. That is, the container holder 50 can be revolved by the motor 66. In the present embodiment, any known motor can be used as the motor 66 (the motor 66 and a motor 78 described later). For example, in the present embodiment, an induction motor (induction motor) can be applied as the motor 66. The rotation speed of the induction motor can be set to an arbitrary value by controlling the frequency of the AC power output from the inverter. However, it is also possible to use a servo motor or PM motor as the motor 66.

  The drive mechanism 60 includes a rotation drive mechanism 70 that rotates the container holder 50. Hereinafter, the rotation driving mechanism 70 will be described.

  The rotation drive mechanism 70 has a rotation gear 72 fixed to the container holder 50. The rotation gear 72 is fixed to the outer periphery of the container holder 50 and rotates concentrically with the container holder 50 (about the rotation axis L2).

  The rotation driving mechanism 70 has a rotation force applying gear 74. The rotation force imparting gear 74 is fixed to the central shaft 62 and rotates concentrically with the central shaft 62.

  The rotation driving mechanism 70 includes a relay gear unit 76. The relay gear unit 76 includes a first relay gear 76-1 that meshes with the rotation gear 72 and a second relay gear 76-2 that meshes with the rotation force imparting gear 74, and the first relay gear 76-1 and the second relay gear. 76-2 are connected and rotated at the same rotational speed. Note that the relay gear unit 76 is supported by a bearing held by a bearing case fixed to the rotating body 10, and is thereby rotatable with respect to the rotating body 10.

  The rotation driving mechanism 70 has a motor 78. The motor 78 plays a role of controlling the rotation speed of the rotation force applying gear 74. Specifically, the motor 78 rotates the pulley 68 fixed to the central shaft 62 at a predetermined rotational speed. In the stirring and defoaming device 1, since the center shaft 62 is fixed to the rotation force applying gear 74, the rotation speed of the rotation force applying gear 74 can be controlled by the motor 78.

  According to the drive mechanism 60 (the rotation drive mechanism 70), the rotation gear 72 and the rotation force applying gear 74 are associated with each other by the relay gear unit 76, so that the rotation gear 72 and the rotation force applying gear 74 are connected to the planetary gear mechanism. Will show the same behavior. Therefore, when the rotating body 10 is rotated by the motor 66 while the rotation speed of the rotation force applying gear 74 is controlled by the motor 78, the rotation gear 72 rotates while revolving. Since the container holder 50 behaves integrally with the rotation gear 72, the drive mechanism 60 can rotate the container holder 50 while revolving.

  In the stirring and defoaming device 1, the rotation number of the rotation force applying gear 74 is controlled by the motor 78, whereby the revolution number and rotation number of the container holder 50 can be freely set. become. However, as a modification, a brake can be used instead of the motor 78 as a mechanism for controlling the rotation speed of the rotation force applying gear 74. Further, in the stirring and defoaming device 1, the drive mechanism (spinning drive mechanism 70) is configured using a gear, but the drive mechanism can also be configured using a power transmission element such as a pulley and a belt ( Not shown).

  The stirring deaerator 1 includes a control unit 90 shown in FIG. The control means 90 plays a role of comprehensively controlling the operation of the stirring and defoaming apparatus 1. The control means 90 can be configured to perform sequence control on the stirring and defoaming device 1. Hereinafter, the control means 90 will be described. FIG. 6 is a diagram for explaining the control means 90.

  The control means 90 includes a microprocessor (CPU 92) and a drive control unit 94 that controls the number of revolutions and the number of rotations of the container holder 50. And CPU92 controls the drive of the stirring deaerator 1 by outputting various signals to the drive control part 94. FIG.

  Here, in the stirring and defoaming apparatus 1, the container holder 50 revolves with the rotation of the rotating body 10, and thus the revolution number of the container holder 50 is controlled by controlling the output of the motor 66. Further, in the stirring deaerator 1, the rotation number of the container holder 50 is controlled by controlling the output of the motor 78. From this, by controlling the outputs of the motor 66 and the motor 78, the container holder 50 can be rotated at a desired number of revolutions (revolutions and rotations).

  For example, when an induction motor is employed as the motors 66 and 78, the drive control unit 94 controls the operation of the inverter and an inverter control unit for setting the frequency of the AC power supplied to the motors 66 and 78 to a predetermined value. Can be realized. Alternatively, when a servo motor is employed as the motors 66 and 78, the drive control unit 94 is realized by a dedicated driver and hardware, and performs various processes for operating the motors 66 and 78 at a desired rotational speed. . Then, the CPU 92 performs a process of transmitting various signals (such as rotation speed data of the storage container 100) to the drive control unit 94 at a predetermined timing. Thereby, the container holder 50 (storage container 100) can be rotated at a desired number of rotations.

  In the present embodiment, the control unit 90 can be configured to repeat the process of increasing and decreasing the number of rotations of the rotating body 10 at a predetermined timing. Specifically, the control unit 90 can be realized by configuring the CPU 92 to repeatedly transmit the acceleration signal and the deceleration signal of the motor 66 to the drive control unit 94. The “predetermined timing” is freely set according to the material M, for example, when the rotational speed of the rotating body 10 exceeds a predetermined value, or when a predetermined time has elapsed from the start of rotation of the rotating body 10. can do.

  In addition, the CPU 92 receives operation data (revolution number data, operation time data, etc. of the storage container 100) input from the operation unit 96 and stores it in a storage unit (not shown) or various information (operations on the display unit 98). The operation data input from the unit 96, the number of revolutions of the storage container 100, the elapsed time, and the like are displayed.

  The stirring and defoaming device 1 further includes a housing (not shown) and a vibration isolating means (such as a vibration isolating wire or a vibration isolating spring) that supports the support substrate 80 in the housing and prevents the support substrate 80 from vibrating. It can be configured. In addition, the stirring and defoaming device may be configured to further include a pressure reducing mechanism for reducing the pressure of at least the inside of the storage container 100 (not shown).

(2) Storage container 100
Next, a storage container 100 applicable to the present embodiment will be described with reference to FIG.

  The storage container 100 is a container in which a material (agitated and defoamed material) M is stored, and includes a container body 110 and a lid body 120 that can be attached to and detached from the container body 110 as shown in FIG. Yes. The lid 120 includes an inner lid 122 and an outer lid 124. The storage container 100 is held by the container holder 50 and behaves integrally with the container holder 50. In the present embodiment, the container holder 50 and the storage container 100 can be configured to include an idling prevention mechanism for preventing idling of both (not shown). At this time, any known mechanism can be employed as the idling prevention mechanism.

(3) Material M
The material M applicable to the present embodiment is not particularly limited as long as it behaves as a fluid, and its composition and use are not particularly limited. Examples of the material M include an adhesive, a sealant, a liquid crystal material, a solder paste, a curable resin material used for molding, a dental impression material, a dental cement (such as a hole filling agent), and a highly viscous liquid medicine. Various materials can be applied. Further, as the material M, it is also possible to apply a mixed material of a paste-like material and a granular material.

(4) Stirring and defoaming method Next, the stirring and defoaming method for the material M according to the present embodiment will be described with reference to FIGS. Here, FIG. 8 is a flowchart for explaining the stirring defoaming method, and FIG. 9 is a timing chart for explaining the stirring defoaming method.

  As shown in FIG. 8, the stirring and defoaming method according to the present embodiment operates a step (step S10) of holding the storage container 100 in which the material M is stored in the container holder 50, and the stirring and defoaming apparatus 1. And a step of rotating the container holder 50 (storage container 100) while revolving (step S12). Thereby, the material M can be stirred and degassed in the storage container 100.

  Note that the number of revolutions, the number of rotations, and the operation time of the container holder 50 in the step of rotating the container holder 50 while revolving (step S12) can be appropriately set by the user according to the properties of the material.

  In the present embodiment, the number of rotations of the rotating body 10 (the number of rotations of the motor 66) can be changed with the passage of time as shown in FIG. Specifically, the rotational speed of the rotating body 10 is increased until the rotational speed of the rotating body 10 reaches the first rotational speed (w1), and then the rotational speed of the rotating body 10 is increased to the second rotational speed (w2). A rotational speed reduction process for reducing the rotational speed of the rotating body 10 until the rotational speed of the rotary body 10 is increased, and then a rotational speed increase for increasing the rotational speed of the rotational body 10 until the rotational speed of the rotational body 10 reaches the first rotational speed (w1). It is possible to repeat the process. And the process which stops rotation of the rotary body 10 is performed after progress for the predetermined time (t) from the rotation start of the rotary body 10. FIG. The specific values of the first rotation speed (w1), the second rotation speed (w2), and the predetermined time (t) can be set as appropriate according to the material, and the specific values are experimental values. Can be derived by: However, as a modification, the set value of the rotation speed of the rotating body 10 can be made constant.

(5) Effect According to the stirring deaerator 1, an increase in temperature of the bearing 30 (bearing case 20) can be reduced during the operation (during the stirring and defoaming process of the material M). Hereinafter, the effect will be described in detail.

  In the stirring and defoaming device 1, when the rotating body 10 rotates, the bearing case 20 and the tubular member 40 also rotate, and centrifugal force acts on the sealed fluid (lubricating liquid L) sealed therein. Incidentally, as shown in FIG. 3, since the tubular member 40 has a shape extending along the circumference C, the magnitude of the centrifugal force acting on the sealed fluid with the rotation of the rotating body 10 is the tubular member 40. Equal in each region along That is, in the stirring defoaming device 1, the gradient of centrifugal force acting on the sealed fluid does not occur along the tubular member 40 during the operation. Therefore, according to the stirring and defoaming device 1, when the sealed fluid flows along the tubular member 40 during the operation, it is necessary to move the sealed fluid against the centrifugal force generated as the rotating body 10 rotates. Absent. From this, according to the stirring deaerator 1, the sealed fluid can easily flow along the tubular member 40 during the operation.

  In other words, according to the stirring and defoaming device 1, when the rotating body 10 is rotated, a region (singularity) in which the centrifugal force acting on the sealed fluid becomes a specific magnitude in the tubular member 40 (internal space 40S). Area) does not occur. If a specific region is generated in the tubular member 40, the encapsulated fluid receives a force toward the specific region or a force away from the specific region, so that it is difficult to cause the encapsulated fluid to flow along the tubular member 40. Become. However, according to the stirring and defoaming device 1, since a unique region does not occur in the tubular member 40, the sealed fluid can easily flow in the direction along the tubular member 40.

  From this, according to the stirring and defoaming device 1, the sealed fluid can be made to flow in the direction along the tubular member 40 only by changing the rotational speed of the rotating body 10, for example. That is, according to the stirring and defoaming device 1, it is possible to flow the sealed fluid without providing a special mechanism for flowing the sealed fluid.

  In the stirring and defoaming device 1, the sealed fluid in the bearing case 20 can be replaced by flowing the sealed fluid along the tubular member 40 even during the operation. That is, according to the stirring and defoaming device 1, it is possible to prevent a situation in which only a part of the sealed fluid comes into contact with the bearing 30.

  Thereby, even when the bearing 30 generates heat, occurrence of a situation in which only a part of the sealed fluid becomes high temperature is prevented, and the temperature of the entire sealed fluid can be increased uniformly. Therefore, the pace of temperature rise of the sealed fluid during the operation of the agitation deaerator 1 can be moderated, and the temperature of the bearing 30 and its surroundings can be prevented from greatly increasing.

  In addition, according to the stirring and defoaming device 1, even when the temperature of the sealed fluid rises due to contact with the bearing 30, the temperature can be lowered when flowing in the tubular member 40. Therefore, it becomes difficult for the temperature of the sealed fluid to rise, thereby preventing the temperature of the bearing 30 from rising significantly. In addition, by making the tubular member 40 into the shape where the heat sink which is not illustrated was attached to the surface, when flowing through the tubular member 40, the temperature of the sealed fluid can be lowered more effectively.

  In addition, according to the stirring defoaming apparatus 1, the lubricating liquid L is used as the sealed fluid. Therefore, it is possible to drive the stirring and defoaming apparatus 1 with the bearing 30 immersed in the lubricating liquid L, and the burden on the bearing 30 can be reduced as compared with the case where the lubricating liquid L is not used. Further, in the stirring and defoaming device 1, the lubricating liquid L is sealed in the internal space 20 </ b> S of the bearing case 20 and the internal space 40 </ b> S of the tubular member 40. Therefore, the amount of the lubricating liquid L that can be used can be increased without increasing the outer shape of the bearing case 20 (the internal space 20S of the bearing case 20). As a result, it is possible to provide an apparatus in which the lubricating liquid L is unlikely to deteriorate, and since the heat capacity of the lubricating liquid L is increased, the temperature change of the lubricating liquid L is unlikely to occur. Furthermore, according to the stirring and defoaming device 1, since the lubricating liquid L in the bearing case 20 is replaced, it is possible to prevent a situation in which only a part of the lubricating liquid L deteriorates.

  Moreover, according to the stirring deaerator 1, the sealed fluid is filled in the internal space 20 </ b> S and the internal space 40 </ b> S. Therefore, the sealed fluid can be uniformly distributed in the internal space 20S and the internal space 40S. From this, it is possible to prevent the center of gravity of the stirring and defoaming device 1 from changing during the operation of the stirring and defoaming device 1, and the operation of the stirring and defoaming device 1 can be stabilized.

(6) Modified Example As a modified example of the present embodiment, the bearing case 20 may have a configuration in which a through hole 25 is formed as shown in FIG. The through hole 25 is configured not to communicate with the space 30 </ b> S for holding the bearing 30 in the bearing case 20. The internal space 40 </ b> S of the tubular member 40 communicates with the through hole 25. That is, in the present modification, the through hole 25 (a space defined by the through hole 25) can be referred to as an internal space of the bearing case 20. Even in such a configuration, the sealed fluid can be easily flowed, and the temperature rise of the bearing case 20 can be efficiently reduced. In the example shown in FIG. 10, the through hole 25 has a shape that extends linearly. However, as another modification, the through hole 25 has a shape that extends in a curved shape (along the circumference C). Is also possible (not shown).

2. Second Embodiment Hereinafter, a second embodiment to which the present invention is applied will be described with reference to FIGS.

(1) Structure of stirring deaerator 2 As shown in FIGS. 11 and 12, the stirring deaerator 2 according to the present embodiment has only one bearing case 20 and a container holder 50. In addition, the stirring and defoaming device 2 has a balance weight 21. The balance weight 21 can be configured to be able to change the distance from the rotation axis L1. With the balance weight 21, the stirring and defoaming device can be operated stably.

  In the stirring and defoaming device 2, as shown in FIGS. 13 and 14, a through hole 24 is formed in the bearing case 20. As shown in FIG. 13, the through hole 24 communicates with the internal space 20 </ b> S of the bearing case 20, and the center thereof is disposed outside the rotation axis (that is, the rotation axis L <b> 2) of the bearing 30. It is formed as follows.

  The stirring and defoaming device 2 according to the present embodiment has a tubular member 42 as shown in FIGS. The tubular member 42 has a shape extending along a circumference C centered on the revolution axis L1 (see FIG. 12). In the present embodiment, both ends of the tubular member 42 are connected to the bearing case 20. That is, the tubular member 42 is configured such that its internal space communicates with the internal space 20 </ b> S of one bearing case 20. As shown in FIG. 13, the tubular member 42 is configured such that the internal space 42 </ b> S communicates with the internal space 20 </ b> S of the bearing case 20 through the through hole 24.

  The stirring and defoaming device 2 according to the present embodiment includes a drive mechanism 75 shown in FIG. The drive mechanism 75 is configured to be able to rotate while revolving the container holder 50 (storage container 100). Hereinafter, an example of the drive mechanism 75 will be described.

  The drive mechanism 75 includes a rotation gear 72, a rotation force applying gear 74, and a relay gear unit 76. In the drive mechanism 75, the rotation force imparting gear 74 is configured so as not to rotate with respect to the support substrate 80. Specifically, in the drive mechanism 75, the central shaft 62 is fixed to the support member 82, and thereby the rotation force applying gear 74 is fixed to the support substrate 80. Moreover, the drive mechanism 75 has only the motor 66 for rotating the pulley 64 (rotating body 10) as a power source.

  According to this drive mechanism 75, the rotational angular velocities of the rotation gear 72 and the rotation force applying gear 74 are related by the relay gear unit 76. In the drive mechanism 75, the rotation force imparting gear 74 is configured so as not to rotate with respect to the support substrate 80. From this, in the drive mechanism 75, the rotation gear 72 shows the same behavior as the planetary gear mechanism. Therefore, when the rotating body 10 is rotated, the rotating gear 72 rotates while revolving. Since the container holder 50 behaves integrally with the rotation gear 72, the drive mechanism 75 can rotate the container holder 50 while revolving. In the drive mechanism 75, the rotation direction of the rotation gear 72 is opposite to the revolution direction. For example, as shown in FIG. 13, when the rotating body 10 is rotated in the first direction (the direction of arrow A), the rotation gear 72 revolves in the first direction and the second direction (the direction of arrow B). ). In the drive mechanism 75, the rotation angular velocity of the rotation gear 72 (container holder 50) is a value obtained by multiplying the revolution angular velocity by a predetermined coefficient.

(2) Effect According to the stirring and defoaming device 2, the tubular member 42 has a configuration in which both ends thereof are connected to one bearing case 20. Therefore, the length of the tubular member 42 can be increased, and the time until the lubricating liquid L discharged from the internal space 20S of the bearing case 20 flows into the internal space 20S can be increased. Therefore, the lubricating liquid L can be sufficiently cooled in the tubular member 42, and the temperature rise of the bearing 30 can be prevented.

  Moreover, according to the stirring and defoaming device 2, the drive mechanism 75 is configured such that the revolution direction and the rotation direction of the container holder 50 are opposite to each other. From this, according to the stirring and defoaming device 2, the fluid (encapsulated fluid) enclosed in the internal space of the bearing case 20 and the tubular member 42 can flow in the direction along the circumference C. Hereinafter, this operation will be described in detail.

  First, in the stirring and defoaming device 2, when the rotating body 10 rotates, the bearing case 20 and the tubular member 42 rotate, and the enclosed fluid also rotates accordingly. However, the moving speed of the sealed fluid is usually slower than that of the rotating body 10. Therefore, the enclosed fluid moves in the tubular member 42 and the bearing case 20 in the direction opposite to the rotation direction of the rotating body 10 as the rotating body 10 rotates. Specifically, in FIG. 13, when the rotating body 10 is rotated in the direction of arrow A, the sealed fluid moves in the direction of arrow a.

  The sealed fluid contacts the rotation shaft 52 of the container holder 50 in the bearing case 20 and receives a force along the rotation direction of the rotation shaft 52. Here, the drive mechanism 75 is configured to rotate the container holder 50 in a direction opposite to the rotation direction (revolution direction) of the rotating body 10. Therefore, in the stirring and defoaming device 2, the sealed fluid flows in a direction opposite to the rotation direction of the rotating body 10 in accordance with the rotation of the rotation shaft 52 of the container holder 50 in a region outside the rotation axis L2 of the internal space 20S. You will receive the power of heading. Specifically, in FIG. 13, when the rotating body 10 is rotated in the direction of arrow A, the rotation shaft 52 rotates in the direction of arrow B, whereby the sealed fluid receives a force in the direction of arrow b. become.

  That is, according to the stirring and defoaming device 2, the direction in which the sealed fluid moves with the rotation of the rotating body 10 (the direction of the arrow a) and the direction of the force acting on the sealed fluid with the rotation of the rotation shaft 52 (the arrow). b direction). Therefore, even if the stirring and defoaming device 2 is not provided with a special mechanism for causing the enclosed fluid to flow, the enclosed fluid can be caused to flow within the bearing case 20 and the tubular member 42.

  In particular, in the stirring and defoaming device 2, the through hole 24 of the bearing case 20 is disposed outside the rotation axis L2. Therefore, when the sealed fluid moves along the circumference C, the sealed fluid flows into a region outside the rotation axis L2 of the internal space 20S and flows out from a region outside the rotation axis L2 of the internal space 20S. Will do. From this, it becomes easy for the sealed fluid to move in a region outside the rotation axis L2 (that is, a region outside the rotation shaft 52), and the above-described effect can be remarkably exhibited. However, the position of the through hole 24 is not limited to this, and can be arranged on the inner side of the rotation axis L2 (not shown).

  Note that, according to the stirring and defoaming device 2, the sealed fluid can be flowed using the force acting on the sealed fluid as the rotation shaft 52 rotates. Therefore, it is possible to adjust the flow rate of the sealed fluid by the friction between the rotation shaft 52 and the sealed fluid. Therefore, the flow rate of the sealed fluid can be set to a desired value by adjusting the shape of the rotation shaft 52, the constituent material of the rotation shaft 52, and the type of the sealed fluid. Further, according to the stirring and defoaming device 2, when the magnitude of the centrifugal force acting on the sealed fluid (that is, the number of rotations of the rotating body 10) changes, the ease of flow of the sealed fluid changes. Therefore, it is possible to adjust the flow rate of the sealed fluid by adjusting the number of rotations of the rotating body 10.

(3) Modified Example As a modified example of the present embodiment, the stirring deaerator can be configured to have a rotation shaft 54 as shown in FIG. Here, the rotation shaft 54 has a configuration in which irregularities are formed on the outer periphery. According to this modification, it is possible to adjust the flow rate of the sealed fluid by adjusting the shape of the rotation shaft 54 (the shape of unevenness, the height and the interval). As another modification, the rotation axis can be configured such that the cross section is a polygon (regular polygon) (not shown).

3. Third Embodiment Hereinafter, a third embodiment to which the present invention is applied will be described with reference to FIGS. 16 and 17.

  As shown in FIGS. 16 and 17, the stirring and defoaming device 3 according to the present embodiment has a hollow tubular member 44. As shown in FIG. 17, the tubular member 44 has a shape extending along a circumference (circumference C) centering on the rotation axis of the rotating body 10 in plan view. The tubular member 44 is configured in a loop shape (endless shape). The tubular member 44 is configured to be able to enclose a desired fluid.

  In the stirring and defoaming device 3, the tubular member 44 is configured so that heat is transferred to and from the bearing case 20. Specifically, the stirring and defoaming device 3 includes a heat conducting member 45 that contacts the tubular member 44 and the bearing case 20. Thereby, heat can be transmitted between the tubular member 44 and the bearing case 20.

(2) Effect According to the stirring and defoaming device 3, heat is transmitted between the bearing case 20 and the tubular member 44. Therefore, even when the bearing case 20 (bearing 30) generates heat during the operation of the stirring and degassing device 3, the heat is transmitted to the tubular member 44, so that the temperature rise of the bearing case 20 is reduced. Can do.

(3) Modified Example As a modified example of the present embodiment, the stirring and defoaming device can be configured to have a flow mechanism 46 as shown in FIG. The flow mechanism 46 is attached to the tubular member 44 and plays a role of causing the enclosed fluid enclosed in the tubular member 44 to flow in a direction along the circumference C. The flow mechanism 46 can be realized by a pump, for example. Specifically, one of the known pumps is installed so that the suction port and the discharge port are arranged on the circumference C, and the discharge direction faces the tangential direction of the circumference C. By doing so, the flow mechanism 46 can be realized.

  According to this stirring and defoaming device, the enclosing fluid can freely flow in the direction along the circumference C by the flow mechanism 46. Therefore, the sealed fluid can be flowed at an optimum value for reducing the temperature rise of the bearing case 20, and the temperature rise of the bearing case 20 can be efficiently reduced. In addition, since the tubular member 44 has a shape extending along the circumference C, a force required for flowing the sealed fluid in the direction along the circumference C can be very small. Therefore, even when a flow mechanism having a small output is used, the sealed fluid can be freely flowed.

  As another modified example, the tubular member 44 may be brought into direct contact with the bearing case 20 without the heat conducting member 45 interposed therebetween, or the tubular member 44 may be configured to penetrate the bearing case 20. It is possible (not shown). Even in these cases, heat can be transferred between the bearing case 20 and the tubular member 44.
