(c) container holder 30

As shown in FIG. 1, the agitating defoaming device 1 includes a container holder 30. The container holder 30 functions to hold the container 100 to be described later. The container holder 30 is held at a position spaced apart from the rotation axis L1 by the rotation of the rotating body 20. Thereby, the container holder 30 revolves around the rotation axis L1 in accordance with the rotation of the rotating body 20.

The container holder 30 is held in such a manner as to be rotatable (rotated) with respect to the rotating body 20. Specifically, in the agitating and defoaming device 1 , the rotation shaft 32 is fixed to the container holder 30 , and the rotation shaft 32 is configured to be held by the rotating body 20 (the bearing holding portion fixed to the rotating body 20 ) via the bearing 34 . Thereby, the container holder 30 can be rotated with respect to the rotating body 20.

Further, in the present embodiment, the container holder 30 is configured such that its rotation axis L2 obliquely intersects the rotation axis L1 (revolution axis). Specifically, the agitating 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 angle of intersection of the rotation axis L1 and the rotation axis L2 is not limited to 45 degrees, but can be appropriately set in accordance with the properties of the material M.

In the present embodiment, the container holder 30 has a structure in which three bosses 36 are attached to the upper end (see FIG. 4(B)), and the boss portion 36 can prevent the container 100 from idling inside the container holder 30.

(d) Drive mechanism

The stirring and defoaming device 1 includes a driving mechanism that rotates the container holder 30 (container 100) while revolving. Next, the structure 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 the present embodiment, when the rotating body 20 is rotated, the container holder 30 (container 100) revolves. Therefore, the motor 42 can be referred to as a revolving drive mechanism for revolving the container holder 30 (container 100). Further, the motor 42 can use any of the conventional motors such as a non-synchronous motor, a servo motor, or a PM motor.

The drive mechanism also has a rotation force attachment mechanism. In the present embodiment, the rotation force adding mechanism is configured to attach a rotation force to the container holder 30 in accordance with the revolution of the container holder 30 (with the rotation of the rotating body 20). Next, the rotation force adding mechanism will be described.

The rotation force attachment mechanism has a rotation pulley 46. The rotation pulley 46 is fixed to the container holder 30 and moves integrally with the container holder 30. Further, in the present embodiment, the rotation pulley 46 is provided on the outer circumference of the container holder 30. Further, the rotation force attachment mechanism has a rotation force additional pulley 48. The rotation force additional pulley 48 is fixed to the outer circumference of the holding member 14. Further, the rotation force adding mechanism has a self-rotating force transmitting mechanism 50 that transmits power between the rotation pulley 46 and the rotation force additional pulley 48. In the present embodiment, the self-rotational force transmitting mechanism 50 includes a first relay pulley 52 and a second relay pulley 54 that are configured to be rotatable relative to the rotating body 20, and are wound around the spinning pulley 46 and the first The first belt 56 on the relay pulley 52; the second belt 58 wound around the rotation force additional pulley 48 and the second relay pulley 54.

With the rotation force applying mechanism, the movement of the rotation pulley 46 is associated with the movement of the rotation force applying pulley 48 by the rotation force transmitting mechanism 50, and the rotation pulley 46 and the rotation force additional pulley 48 appear to be the same as the planetary gear mechanism. exercise. In the present embodiment, the rotation force applying pulleys 48 are fixed to the holding member 14, and when the rotating body 20 is rotated, the rotation pulley 46 revolves around the rotation axis L1 and rotates around the rotation axis L2. . In other words, in the agitating and defoaming device 1, when the rotary 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 revolves while revolving.

Further, as a modification, the drive mechanism is configured such that the rotation force applying pulley 48 can be rotated with respect to the holding member 14, and further includes an adjustment mechanism for rotating the rotation force applying pulley 48 at a desired rotation speed (not shown). Show). As previously explained, in the drive mechanism, the self-rotating force transmitting mechanism 50 acts to associate the rotational speed of the spinning pulley 46 with the rotational speed of the rotational force additional pulley 48. Therefore, by rotating the rotation pulley 46 while rotating the rotation body 20 and controlling the rotation speed of the rotation force applying pulley 48, the rotation speed of the rotation pulley 46 can be controlled. Further, the adjustment mechanism can be realized by any one of the conventional mechanisms such as a motor or a brake.

Further, as another variation, it is also possible to use a gear as a power transmission element instead of a pulley and a belt (not shown).

(e) Control unit 60

The agitating defoaming device 1 includes a control unit 60 as shown in FIG. The control unit 60 plays the role of collectively controlling the action of the agitating and defoaming device 1. Next, the control unit 60 will be described. FIG. 2 is a diagram for explaining the control unit 60.

The control unit 60 includes a microprocessor (CPU 62) and a drive control unit 64 that controls the revolution drive mechanism (motor 42). Further, by causing the CPU 62 to output various signals to the drive control unit 64 based on the operation data (for example, the data input by the user's cooperation material M), the stirring defoaming device 1 (the rotation driving mechanism for driving the container holder 30) is controlled. )Actions.

As described above, in the agitating and defoaming device 1, since the container holder 30 revolves in accordance with the rotation of the rotating body 20, the revolution speed of the container holder 30 can be 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 revolution speed.

For example, when a non-synchronous motor is used as the motor 42, the drive control unit 64 controls the operation of the inverter, and can be realized by an inverter control unit for setting the frequency of the AC power supplied to the motor 42 to a predetermined value. Alternatively, when the servo motor is used as the motor 42, the drive control unit 64 is realized by a dedicated driver and a hardware, and performs various processes for operating the motor 42 at a desired number of revolutions. Further, the drive control unit 64 may be configured to acquire the rotation speed information of the container holder 30 detected by the rotation sensor 66 (for example, obtained by the CPU 62), and perform various types of rotations for controlling the rotation speed of the rotary body 20 based on the rotation speed information. deal with.

Then, the CPU 62 performs a process of transmitting various signals (target rotational speed data of the container holder 30, etc.) to the drive control unit 64 at a predetermined timing. Thereby, the container holder 30 can be rotated at a desired number of revolutions.

Further, in the present embodiment, the CPU 62 is configured to be able to acquire the rotational speed information (the rotational speed information of the container holder 30) of the rotating body 20 via the rotation sensor 66. Further, the CPU 62 can also perform processing for associating the rotational speed information with the elapsed time and storing it in a storage unit (not shown). Further, the CPU 62 can also be configured to perform arithmetic processing on the rotation speed information of the container holder 30 based on the rotational speed information of the rotating body 20. In other words, in the stirring and defoaming device 1, since the rotation force applying pulley 48 is configured to be non-rotatable, if the rotation speed of the rotating body 20 is clearly known, the rotation speed of the container holder 30 can be calculated from the size data of each element of the power transmission mechanism. .

Further, the CPU 62 also receives the operation data input from the operation unit 68, stores it in the storage unit (not shown), and causes the display unit 69 to display each of the information (the motion data input from the operation unit 68 and the stirring and defoaming). Processing of the operating conditions of the device 1.

In the present embodiment, as shown in FIG. 3(B), in the cross section taken along the plane including the center line 120L, the first inclined region 160 and the second inclined region 170 have a shape extending along the circle C1. Further, in the present embodiment, the circle C1 is a circle that is disposed at the center passing through the lower end of the side surface portion 120 and on the normal line of the lower end. That is, the circle C1 is a circle in which the side surface portion 120 is a tangent line, whereby the side surface portion 120 is smoothly connected to the first inclined region 160. Further, in the present embodiment, the circle C1 is a circle having a diameter of half the diameter of the side surface portion 120. Therefore, the deepest region 150 is disposed in the intermediate portion between the side surface portion 120 and the center line 120L.

As shown in FIG. 3(A) and FIG. 3(C), the container 100 has an anti-idle mechanism. The anti-idle mechanism acts to prevent the container 100 from idling within the container holder 30. That is, the container 100 can be held by the container holder 30 by the anti-idle mechanism and moved integrally with the container holder 30. In the present embodiment, the anti-idle mechanism is realized by the recess 182 which is circumferentially mounted on the outer circumference of the container 100. That is, in the present embodiment, as shown in FIGS. 4(A) and 4(B), by fitting the concave portion 182 to the convex portion 36 of the container holder 30, it is possible to prevent the container 100 from idling in the container holder 30. .

In the present embodiment, the cover 190 is configured to include an inner cover 192 and an outer cover 194.

(3) Material M

The material M which can be applied to the present embodiment is not particularly limited as long as it has a material as a fluid. As the material M, a material containing only a fluid component (resin or the like) or a material containing a particulate component (powder component) in addition to the fluid component can be used. The material M can use, for example, a binder, a sealant, a liquid crystal material, a mixed material of a phosphor and a resin including an LED, a solder paste, a curable resin material for press molding, a dental impression material, a dental cement powder. Various materials such as (filler, etc.) and liquid chemicals.

Thereby, the defoaming material M can be stirred in the container 100.

(5) Effect

Next, the operation and effect of the container 100 and the stirring and defoaming device 1 of the present embodiment will be described.

As described above, the container 100 is configured such that the first inclined region 160 and the second inclined region 170 have a shape along the circle C1 in a cross section taken along a plane including the center line 120L. According to this configuration, even when the boss portion (the central region 140 and the second inclined region 170) is provided at the center of the bottom portion 130, the bottom portion 130 can be made smooth, and the bottom portion 130 can be made. The curvature of one inclined region 160 and second inclined region 170) becomes sufficiently small. Therefore, by using the container 100, when the material M is subjected to the stirring and defoaming treatment, it is possible to prevent the occurrence of the material from staying in the center of the bottom portion 130, and the material M can be smoothly moved along the bottom portion 130. That is, with the container 100, a region where the flow of the material M is weakened is less likely to occur on the bottom portion 130. Thus, by using the container 100, it is less likely to cause uneven agitation of the material M or precipitation of a component (particle component) of the material M during the agitation and defoaming treatment of the material M.

Further, the container 100 is in a shape that smoothly connects the side surface portion 120 and the bottom portion 130 (first inclined region 160). Therefore, the material M can be smoothly moved at the boundary between the side surface portion 120 and the bottom portion 130, and the unevenness of the stirring of the material M is less likely to occur at the boundary between the side surface portion 120 and the bottom portion 130.

Further, the container 100 is in a shape that smoothly connects the central region 140 and the second inclined region 170. Therefore, the material M can be smoothly moved at the boundary between the central region 140 and the second inclined region 170, and the agitation unevenness of the material M is less likely to occur at the boundary between the central region 140 and the second inclined region 170.

Further, the container 100 has a shape in which the central portion 140 becomes smaller in diameter upward. Therefore, the area of the front end of the central region 140 can be made small, and it is difficult to cause the material M (particularly, the particle component) to precipitate to the tip end.

(6) Variations

Next, a modification of this embodiment will be described.

Next, a container 200 which is a modification of the present embodiment will be described with reference to Figs. 6(A) and 6(B).

As shown in FIG. 6(A), the container 200 has an inner surface 210. The inner surface 210 is a face that divides an inner space for accommodating the material M. Also, the material M is held in the inner space and is in contact with the inner surface 210 (a part thereof).

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

As shown in FIG. 6(A), the inner surface 210 has a bottom portion 230. The bottom portion 230 includes a central region 240, a deepest region 250, a first inclined region 260 connecting the deepest region 250 and the side portion 220, and a second inclined region 270 connecting the deepest region 250 and the central region 240. In the present embodiment, the deepest region 250 is disposed in the intermediate portion of the side portion 220 and the center line 220L thereof. Moreover, in the embodiment, the first inclined area 260 and the second inclined area 270 is a shape extending along the circle C2. Here, the circle C2 is a circumference that is disposed at the center on the normal line that passes through the lower end of the side surface portion 220 and extends from the lower end. Further, the diameter of the circle C2 is slightly shorter than half the diameter of the side portion 220.

Then, as shown in FIG. 6(B), the container 200 is configured to be held by the container holder via the adapter 300.

The container 200 has the above-described configuration. According to this configuration, even when the boss 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 can be made smooth. The curvature of the bottom portion 230 (the first inclined region 260 and the second inclined region 270) can be made sufficiently small. Therefore, by using the container 200, when the material M is subjected to the stirring and defoaming treatment, the stirring unevenness of the material M or the precipitation of the component (particle component) of the material M is less likely to occur.

Further, if the diameter of the circle C2 is about 90% of the length of the half of the diameter of the side surface portion 220 (preferably about 95%), the deepest region 250 can be disposed in the middle of the side surface portion 220 and the center line 220L. The area can fully exert the above effects.

Further, conversely, as shown in FIG. 7, the first inclined region 262 and the second inclined region 272 may have a shape extending along the circle C3 in a cross section taken along a plane including the center line of the side surface portion. Here, the diameter of the circle C3 is slightly longer than the length of half of the diameter of the side surface portion. When the diameter of the circle C3 is about 110% of the length of the half of the diameter of the side surface portion (preferably about one hundred and fifty-five percent), the above effects can be sufficiently exhibited.

Further, as another variation, as shown in FIG. 8, the first inclined region 264 and the second inclined region 274 can be extended along the circle C4 in a cross section taken along a plane including the center line 222L of the side surface portion 222. shape. Here, the circle C4 is a circle that is in contact with the side surface portion 222 and the center line 222L. In the case of this configuration, when the material M is subjected to the stirring and defoaming treatment, the stirring unevenness of the material M or the precipitation of the component (particle component) of the material M is less likely to occur.

Alternatively, as shown in FIGS. 9(A) and 9(B), the container may be formed such that the central region 242 is shifted from the center line 224L of the side surface portion 224. In the case of such a configuration, when the material M is subjected to the stirring and defoaming treatment, the stirring unevenness of the material M or the precipitation of the component (particle component) of the material M is less likely to occur.
