A holding member 14 for holding a rotating shaft 22 of the rotating body 20 described later is attached to the support substrate 12. The housing 10 has a door configured to be openable and closable. When the door is opened, the container holder 30 is exposed, and the container 100 can be attached to and detached from the container holder 30.

(B) Rotating body 20
As shown in FIG. 1, the stirring and deaerator 1 includes a rotating body 20. The rotating body 20 is configured to be rotatable with respect to the support substrate 12 (housing 10). Specifically, in the stirring and defoaming device 1, a rotating shaft 22 is fixed to the rotating body 20, and the rotating shaft 22 is held by the holding member 14 via a bearing. Thereby, the rotating body 20 can be rotated with respect to the support substrate 12. In the stirring and degassing apparatus 1, the rotation axis L <b> 1 of the rotating body 20 and the extending direction of the rotating shaft 22 coincide with each other.

(C) Container holder 30
As shown in FIG. 1, the stirring and deaerator 1 includes a container holder 30. The container holder 30 plays a role of holding a container 100 described later. The container holder 30 is held at a position of the rotating body 20 that is separated from the rotation axis L1 by a predetermined distance. Thereby, the container holder 30 revolves around the rotation axis L <b> 1 as the rotating body 20 rotates.

  The container holder 30 is held so as to be able to rotate (rotate) with respect to the rotating body 20. Specifically, in the stirring and defoaming device 1, the rotation shaft 32 is fixed to the container holder 30, and the rotation shaft 32 is connected to the rotating body 20 (bearing holding portion fixed to the rotating body 20) via a bearing 34. ). Thereby, the container holder 30 can rotate with respect to the rotating body 20.

  In the present embodiment, the container holder 30 is configured such that its rotation axis L2 obliquely intersects with the rotation axis L1 (revolution axis). Specifically, the stirring and defoaming device 1 is configured such that the rotation axis L2 intersects the rotation axis L1 at an angle of 45 degrees. However, the crossing angle between the rotation axis L1 and the rotation axis L2 is not limited to 45 degrees, and can be appropriately set according to the properties of the material M.

  In the present embodiment, the container holder 30 has a configuration in which three convex portions 36 are attached to the upper end (see FIG. 4B). The convex portion 36 can prevent the container 100 from spinning around inside the container holder 30. However, the container holder 30 may be configured not to have the convex portion 36 (not shown).

  In the present embodiment, only one container holder 30 is attached to the rotating body 20. In the present embodiment, a balance weight 38 is attached to the rotating body 20. The rotating body 20 can be stably rotated by the balance weight 38. In the present embodiment, the balance weight 38 is configured to be able to change the distance from the rotation axis L1.

(D) Drive mechanism The stirring and defoaming device 1 includes a drive mechanism that rotates the container holder 30 (container 100) while revolving. Hereinafter, the configuration of the drive mechanism will be described.

  The drive mechanism has a motor 42. The motor 42 plays a role of rotating the rotating body 20 (the rotating shaft 22). In this Embodiment, when the rotary body 20 rotates, the container holder 30 (container 100) will revolve. Therefore, the motor 42 can be referred to as a revolution drive mechanism for causing the container holder 30 (container 100) to revolve. As the motor 42, any known motor such as an induction motor, a servo motor, or a PM motor can be used.

  The drive mechanism also has a rotation force applying mechanism. In the present embodiment, the rotation force applying mechanism is configured to apply a rotation force to the container holder 30 as the container holder 30 revolves (with rotation of the rotating body 20). Hereinafter, the rotation force application mechanism will be described.

  The rotation force application mechanism has a rotation pulley 46. The rotation pulley 46 is fixed to the container holder 30 and behaves integrally with the container holder 30. In the present embodiment, the rotation pulley 46 is provided on the outer periphery of the container holder 30. The rotation force application mechanism has a rotation force application pulley 48. The rotation force applying pulley 48 is fixed to the outer periphery of the holding member 14. The rotation force application mechanism has a rotation power transmission mechanism 50 that transmits power between the rotation pulley 46 and the rotation force application pulley 48. In the present embodiment, the rotation power transmission mechanism 50 is wound around a first relay pulley 52 and a second relay pulley 54 configured to be rotatable with respect to the rotating body 20, and the rotation pulley 46 and the first relay pulley 52. The first belt 56 and the second belt 58 wound around the rotation force applying pulley 48 and the second relay pulley 54 are configured.

  According to the rotation force application mechanism, the rotation power transmission mechanism 50 associates the behavior of the rotation pulley 46 with the behavior of the rotation force application pulley 48, and the rotation pulley 46 and the rotation force application pulley 48 are similar to the planetary gear mechanism. Will show the behavior. In this embodiment, since the rotation force imparting pulley 48 is fixed to the holding member 14, when the rotating body 20 is rotated, the rotation pulley 46 revolves around the rotation axis L1 while rotating around the rotation axis L1. It will rotate around L2. That is, in the stirring and defoaming apparatus 1, when the rotating body 20 is rotated by the motor 42, the rotation pulley 46 rotates while revolving, and the container holder 30 fixed to the rotation pulley 46 rotates while revolving.

  As a modification, the drive mechanism is configured to rotate the rotation force applying pulley 48 with respect to the holding member 14 and further includes an adjustment mechanism for rotating the rotation force applying pulley 48 at a desired number of rotations. It is also possible (not shown). As described above, in the drive mechanism, the rotation power transmission mechanism 50 plays a role of associating the rotation speed of the rotation pulley 46 with the rotation speed of the rotation force applying pulley 48. Therefore, it is possible to control the rotation speed of the rotation pulley 46 by adjusting the rotation speed of the rotation force applying pulley 48 while revolving the rotation pulley 46 (rotating the rotating body 20). Note that this adjustment mechanism can be realized by any mechanism that is already known, such as a motor or a brake.

  As another modification, it is also possible to use gears (not shown) instead of pulleys and belts as power transmission elements.

(E) Control means 60
The stirring defoaming apparatus 1 includes a control means 60 shown in FIG. The control means 60 plays a role of comprehensively controlling the operation of the stirring and defoaming apparatus 1.

  The control means 60 includes a microprocessor (CPU 62) and a drive control unit 64 that controls the revolution drive mechanism (motor 42). And CPU62 outputs various signals to the drive control part 64 based on operation data (For example, the data which the user input according to the process conditions of the material M), The stirring deaerator 1 (container holder 30) The operation of the rotational drive mechanism for driving the motor is controlled.

  As described above, in the stirring and defoaming device 1, the container holder 30 revolves with the rotation of the rotating body 20, and thus the revolution number of the container holder 30 is controlled by controlling the output of the motor 42. That is, by controlling the output of the motor 42, the container holder 30 can be revolved at a desired number of revolutions.

  For example, when an induction motor is employed as the motor 42, the drive control unit 64 is realized by an inverter control unit for controlling the operation of the inverter and setting the frequency of the AC power supplied to the motor 42 to a predetermined value. Can do. Alternatively, when a servo motor is employed as the motor 42, the drive control unit 64 is realized by a dedicated driver and hardware, and performs various processes for operating the motor 42 at a desired rotational speed. Further, the drive control unit 64 acquires the rotation speed information of the container holder 30 detected by the rotation sensor 66 (for example, acquired via the CPU 62), and the rotation speed of the rotating body 20 is determined based on the rotation speed information. It is also possible to configure to perform various processes for adjustment.

  And CPU62 performs the process which transmits various signals (The target rotation speed data of the container holder 30, etc.) to the drive control part 64 at a predetermined timing. Thereby, the container holder 30 can be rotated at a desired number of rotations.

  In the present embodiment, the CPU 62 is configured to be able to acquire the rotation speed information of the rotating body 20 (rotation speed information of the container holder 30) via the rotation sensor 66. The CPU 62 can also perform a process of storing the rotation speed information in a storage unit (not shown) in association with the elapsed time. In addition, the CPU 62 can be configured to calculate the rotation number information of the container holder 30 based on the rotation number information of the rotating body 20. That is, in the stirring and defoaming device 1, the rotation force applying pulley 48 is configured to be non-rotatable. Therefore, if the number of rotations of the rotating body 20 becomes clear, the container holder 30 is obtained from the size data of each element of the power transmission mechanism. It is possible to calculate the number of rotations.

  Further, the CPU 62 receives the operation data input from the operation unit 68 and stores it in a storage unit (not shown), or displays various information (operation data input from the operation unit 68, stirring deaeration device) on the display unit 69. 1) is displayed.

That is, the circle C1 is a circle having the side surface portion 120 as a tangent line, and thus the side surface portion 120 and the first inclined region 160 are smoothly connected. In the present embodiment, the circle C1 is a circle having a diameter that is half the diameter of the side surface portion 120. Therefore, the deepest region 150 is disposed in an intermediate region between the side surface portion 120 and the center line 120L.

  As shown in FIGS. 3A and 3C, the container 100 has an idling prevention mechanism. The idling prevention mechanism plays a role of preventing the container 100 from idling in the container holder 30. In other words, the container 100 is held by the container holder 30 and can behave integrally with the container holder 30 by the idling prevention mechanism.

Can be moved to. That is, according to the container 100, it becomes difficult to generate | occur | produce the area | region where the flow of the material M becomes weak on the bottom part 130. FIG. From this, by using the container 100, when the material M is stirred and defoamed, uneven stirring of the material M and sedimentation of the components (particle components) of the material M are less likely to occur.

  Further, the container 100 has a shape in which the side surface portion 120 and the bottom portion 130 (first inclined region 160) are smoothly connected. Therefore, the material M can be smoothly moved at the boundary between the side surface portion 120 and the bottom portion 130, and the uneven stirring of the material M hardly occurs at the boundary between the side surface portion 120 and the bottom portion 130.

The container 100 has a shape in which the central region 140 and the second inclined region 1 70 are smoothly connected. Therefore, at the boundary between the central region 140 and the second inclined region 1 7 0, it is possible to smoothly move the material M, at the boundary between the central region 140 and the second inclined region 1 7 0, stirred unevenness of the material M Is less likely to occur.

  Further, the container 100 has a shape in which the central region 140 has a diameter that decreases upward. Therefore, the area of the front end of the central region 140 can be reduced, and the sedimentation of the material M (particularly the particle component) on the front end is less likely to occur.

(6) Modified Example Next, a modified example of the present embodiment will be described.

  Hereinafter, with reference to FIG. 6 (A) and FIG. 6 (B), the container 200 as a modification of this Embodiment is demonstrated.

  The container 200 has an inner surface 210 as shown in FIG. The inner surface 210 is a surface that defines an internal space for storing the material M. The material M is held in the internal space and comes into contact with the inner surface 210 (a part thereof).

  The inner surface 210 has a side surface portion 220 as shown in FIG. The side part 220 is a columnar region. The side part 220 has a tapered shape as shown in FIG. Specifically, the side surface portion 220 is formed in a tapered columnar shape, and the diameter of the side surface portion 220 becomes narrower toward the lower side of the side surface portion 220 (see FIG. 6A). That is, the side part 220 has its normal line facing upward from the horizontal plane.

  The inner surface 210 has a bottom 230 as shown in FIG. The bottom portion 230 includes a central region 240, a deepest region 250, a first inclined region 260 that connects the deepest region 250 and the side portion 220, and a second inclined region 270 that connects the deepest region 250 and the central region 240. In the present embodiment, deepest region 250 is arranged in an intermediate region between side surface portion 220 and its center line 220L. And in this Embodiment, the 1st inclination area | region 260 and the 2nd inclination area | region 270 become a shape extended along the circle C2. Here, the circle C <b> 2 is a circumference that passes through the lower end of the side surface portion 220 and is centered on a normal extending from the lower end. Further, the diameter of the circle C2 is slightly shorter than half of the diameter of the side surface portion 220.

  And the container 200 is comprised so that it may be hold | maintained at a container holder via the adapter 300, as shown to FIG. 6 (B).

  The container 200 has the above-described configuration, and according to this configuration, even when the convex portion (the central region 240 and the second inclined region 270) is provided at the center of the bottom portion 230, the entire bottom portion 230 has a smooth surface. In addition, the curvature of the bottom 230 (the first inclined region 260 and the second inclined region 270) can be sufficiently reduced. Therefore, by using the container 200, when the material M is stirred and defoamed, uneven stirring of the material M and sedimentation of the component (particle component) of the material M are less likely to occur.

  If the diameter of the circle C2 is up to about 90 percent (more preferably about 95 percent) of the half length of the diameter of the side surface portion 220, the deepest region 250 is an intermediate region between the side surface portion 220 and the center line 220L. It is possible to sufficiently exhibit the above effect.

It is also possible. Here, the circle C4 is a circle in contact with the side surface portion 222 and the center line 222L. Even in this configuration, when the material M is stirred and defoamed, uneven stirring of the material M and sedimentation of the components (particle components) of the material M are less likely to occur.

(7) Reference example
As shown in FIG. 7, the first inclined region 262 and the second inclined region 272 may have a shape extending along a circle C3 in a cross section cut along a plane including the center line of the side surface portion. Here, the diameter of the circle C3 is slightly longer than half the diameter of the side surface portion. If the diameter of the circle C3 is up to about 110 percent (more preferably about 105 percent) of the half length of the diameter of the side surface portion, the above effect can be sufficiently exerted.
Alternatively, as shown in FIGS. 9A and 9B, the container can be configured such that the central region 242 is displaced from the center line 224L of the side surface portion 224. Even in this configuration, when the material M is stirred and defoamed, uneven stirring of the material M and sedimentation of the components (particle components) of the material M are less likely to occur.
