Description

Technical Field

[0001] The present invention relates to a stirring device in which a stirring container capable of stirring a stirring material moves up and down.

Background Art

[0002] A stirring device is used to finely divide and stir a liquid or a mixture of liquid and solid in cosmetics, foods, chemicals, or pharmaceuticals as a material. The stirring device includes a stirring container in which rotating blades provided on a rotating shaft rotate to stir the material, and a drive unit for rotating the rotating shaft.

[0003] There are various types of materials to be stirred, and it is necessary to wash the stirring container and the stirring blades every time the type is switched. Therefore, it is desired to improve the washability of each member as much as possible.

[0004] Patent Document 1 describes a tester for testing stirring in small lots, in which the stirring container is lowered to the lowest end and the stirring container is tilted to improve washability. <​​​​​​​​​​​​​​​​​​​​​​​​​

[0008] To solve the above problems, the present invention provides a stirring device in which a stirring container that can be filled with stirring material is separated from a rotary drive unit that can rotate stirring blades and is capable of moving up and down, The rotational drive unit has a gear rotating part capable of rotating the stirring blade and an outer cylindrical part located outside the gear rotating part. The stirring container can rise to its uppermost position and come into close contact with the outer cylindrical portion. The present invention provides a stirring device characterized in that the outer cylindrical portion is equipped with an upper connecting portion that can be connected to and disconnected from an upper cylindrical portion located above the outer cylindrical portion.

[0009] This configuration improves the cleanability of the drive unit (gear rotation unit) of the stirring blades, as the drive unit of the stirring blades is contaminated with the stirring material. By releasing the upper coupling and lowering the stirring container, the gear rotation unit is exposed.

[0010] The stirring device may be configured such that the stirring container can be lowered together with the outer cylindrical portion until at least the gear holding portion is exposed by releasing the upper coupling portion.

[0011] This configuration allows the gear holder to be exposed and cleaned.

[0012] The stirring device may be configured such that the upper coupling portion is connected, allowing the stirring container to descend until at least the stirring blades are exposed.

[0013] This configuration allows the stirring blades to be exposed and cleaned.

[0014] The stirring device may be configured such that the upper connecting part is connected, allowing the stirring container to descend to its lowest point and tilt.

[0015] This configuration allows for the discharge of the stirring material from the stirring vessel and improves the cleanability of the stirring vessel. [Effects of the Invention]

[0016] The present invention provides a stirring device that can improve the cleanability of the drive unit of the stirring blade when the drive unit of the stirring blade is contaminated with the stirring material. [Brief explanation of the drawing]

[0018] The stirring device in Embodiment 1 of the present invention will be described with reference to the drawings. Figure 1 is a perspective view of the stirring device in Embodiment 1 of the present invention. Figure 2 shows the stirring container in Embodiment 1 of the present invention in close contact with the outer cylindrical part. Figure 3 shows the stirring container in Embodiment 1 of the present invention in a state where it has descended together with the outer container. Figure 4 shows the stirring container in Embodiment 1 of the present invention in a state where it has descended on its own.

[0019] The stirring device 100 in Example 1 is a stirring device capable of stirring stirring materials such as happo materials, facial cleansing cream with scrub, hair wax, and chemical products. It is a device that stirs by revolving together with a scraper around the central rotating shaft 61 while rotating two stirring blades 20. Also, the stirring device 100 in Example 1 is used for experiments and tests before mass production, and the capacity of the glass container 11 located inside the stirring container 10 is as small as 3 liters. Therefore, it is miniaturized so that it can be placed in a narrow space as a stirring device. Furthermore, since the stirring device 100 of Example 1 has a high-speed turbine blade 30 capable of high-speed rotation, an emulsification process can be performed after stirring the materials, so that the two processes of stirring and emulsification can be carried out in one batch.

[0020] The general configuration of the stirring device 100 includes a stirring container 10 into which materials can be filled, two stirring blades 20 (20a, 20b) capable of stirring the materials in the glass container 11 inside the stirring container 10, a high-speed turbine blade 30 rotatable by a high-speed turbine blade rotating shaft 31 provided at a position different from the stirring blade attachment parts 21 (21a, 21b) which are the rotating shafts of the stirring blades 20 (20a, 20b), a scraper (not shown) that stirs while contacting the inner surface of the glass container 11, a gear rotating part 40 capable of rotating both the stirring blade attachment parts 21 (21a, 21b) of the stirring blades 20 (20a, 20b) and the high-speed turbine blade rotating shaft 31 of the high-speed turbine blade 30, a gear group 60 that connects the stirring blade attachment parts 21 (21a, 21b) of the stirring blades 20 (20a, 20b) and the high-speed turbine blade rotating shaft 31 of the high-speed turbine blade 30 in a sealed gear group case 50 inside the gear rotating part 40, grease 70 filled in the gear group case 50, and a display part 80.

[0021] The glass container 11 located inside the stirring container 10 is for putting in materials and stirring them with the stirring blades 20, and has a capacity of 3 liters. Since the stirring device 100 is used as a testing machine, the outer wall is composed of double glass, and the stirring state inside can be visually recognized from the outside. Also, cold water or warm water can be circulated between the glasses to cool or heat the inside of the glass container 11.

[0022] The stirring blades 20 consist of two blades (20a and 20b), each capable of rotating at 25 to 250 rpm via the stirring blade mounting section 21 (21a and 21b). The high-speed turbine blades 30 can rotate at 1,000 to 10,000 rpm via the high-speed turbine blade rotation shaft 31. The stirring blades 20 (20a and 20b), the high-speed turbine blades 30, and the scraper can revolve at 10 to 100 rpm via the central rotation shaft 61.

[0023] The stirring blades 20 rotate at 25 to 250 rpm each, allowing for sufficient mixing of the materials. Furthermore, the high-speed turbine blades 30 rotate at 1,000 to 10,000 rpm, enabling simultaneous emulsification.

[0024] The central rotating shaft 61 rotates by the rotation of the motor 62. As the central rotating shaft 61 rotates, the stirring blades 20 (20a, 20b) rotate and revolve, a scraper (not shown) revolves, and the rotational speed is increased by the gear group 60 shown in Figure 2, causing the high-speed turbine blades 30 to rotate and revolve.

[0025] The gear group 60 is housed in a sealed gear group case 50, which is completely filled with grease 70. When the gear group 60 is driven, the inside of the sealed gear group case 50 becomes quite hot. Therefore, the grease 70 used is a solid lubricant (metal grease) with excellent anti-seizure and anti-galling properties and a heat resistance of over 800°C. During high-speed rotation, centrifugal force ejects the grease from the tooth surfaces, causing it to circulate and flow within the sealed gear group case 50. This suppresses premature deterioration of the grease near the gear group, and is expected to extend the lifespan of the gear group. Furthermore, after the gears stop, the grease that has temporarily separated from the tooth surfaces due to centrifugal force flows again and reattaches to the tooth surfaces. This also suppresses premature deterioration of the grease near the gear group, and is expected to extend the lifespan of the gear group.

[0026] The stirring blades 20 (20a, 20b) can be attached to or detached from the stirring blade mounting section 21 (21a, 21b). Similarly, the high-speed turbine blades 30 can be attached to or detached from the high-speed turbine blade mounting section 31. This allows the stirring blades 20 (20a, 20b) and the high-speed turbine blades 30 to be easily removed for cleaning and inspection.

[0027] The upper end surface of the stirring container 10 can be raised and lowered by a drive unit (not shown) from the uppermost end, which is in close contact with the lower end surface of the outer cylindrical portion 41 located outside the gear rotating portion 40, to the lowest end on which the stirring container 10 can be tilted. The outer cylindrical portion 41 has a substantially cylindrical shape and is provided with multiple material input ports 43 on its circumferential surface, allowing stirring material to be added at any time. Furthermore, the lower end of the outer cylindrical portion 41 is provided with a lower coupling portion 45 that can be connected to and disconnected from the upper end of the stirring container 10 located below the outer cylindrical portion 41, and an upper coupling portion 44 that can be connected to and disconnected from the upper end of the upper cylindrical portion 42 located above the outer cylindrical portion 41 (see Figure 1). In Embodiment 1, the upper coupling portion 44 and the lower coupling portion 45 are made of clamping material that can be connected or disconnected with a single touch, but other configurations are also possible. For example, screw fastening with bolts can be used.

[0028] As shown in Figure 3, the stirring container 10 can be lowered together with the outer cylindrical part 41 until the upper coupling part 44 is released and the gear rotating part 40 and stirring blades 10 are exposed. At this time, the lower coupling part 45 may be coupled or released, but even if it is released, the outer cylindrical part 41 will lower together with the stirring container 10 due to its own weight. As a result, the gear rotating part 40, stirring blades 20, high-speed turbine blades 30, and scrapers (not shown) are exposed, and cleaning is greatly improved. In particular, the gear rotating part 40 is contaminated by adhesion when stirring material is added and by splashing of stirring material due to the rotation of the stirring blades 20, etc., but cleaning and maintenance of this part becomes easier.

[0029] Furthermore, as shown in Figure 4, the upper coupling part 44 can be coupled and the lower coupling part 45 released, allowing the stirring container 10 to be lowered until at least the stirring blades 20 are exposed. This exposes the stirring blades 20, the high-speed turbine blades 30, and a scraper (not shown), improving cleanability. In addition, the stirring blades 20 and the high-speed turbine blades 30 can be removed for cleaning and maintenance.

[0030] Furthermore, by connecting the upper coupling part 44 and releasing the lower coupling part 45, the stirring container 10 can be lowered to its lowest point and tilted sideways. This allows the stirring material inside the stirring container 10 to be discharged and improves the cleanability of the inside of the stirring container 10.

[0031] In Example 1, the system was configured with two stirring blades, but this is not necessarily the only option, and the configuration can be changed as appropriate. For example, it could have one blade or three or more.

[0032] Furthermore, in Example 1, the high-speed turbine blades were configured to rotate at a maximum speed of 10,000 rpm, but this is not necessarily limited to this configuration and can be modified as appropriate. For example, the maximum speed could be 9,000 rpm or even 11,000 rpm. Also, two or more high-speed turbine blades may be provided.

[0033] Furthermore, although the first embodiment is configured to include a lower connecting portion 45, it is not necessarily limited to this and can be modified as appropriate. For example, the lower connecting portion 45 may not be provided. Even without the lower connecting portion 45, when the stirring container 10 rises, the lower end surface of the outer cylindrical portion 41 and the upper end surface of the stirring container 10 can be in close contact, and when it descends, the lower end surface of the outer cylindrical portion 41 and the upper end surface of the stirring container 10 can separate, allowing only the stirring container 10 to descend.

[0034] Furthermore, in Example 1, the material input port 43 was configured to be located on the outer cylindrical portion 41, but this is not necessarily limited to this configuration and can be modified as appropriate. For example, it may be located on the container 10 or the upper cylindrical portion 42.

[0035] Thus, in Example 1, the stirring container, which can be filled with the stirring material, is a stirring device that can be raised and lowered separately from the rotary drive unit that can rotate the stirring blades, The rotational drive unit has a gear rotating part capable of rotating the stirring blade and an outer cylindrical part located outside the gear rotating part. The stirring container can rise to its uppermost position and come into close contact with the outer cylindrical portion. The stirring device is characterized in that the outer cylindrical portion is equipped with an upper connecting portion that can be connected to and disconnected from an upper cylindrical portion located above the outer cylindrical portion. In cases where the drive unit (gear rotating part) of the stirring blade is contaminated with the stirring material, the cleanability of the drive unit of the stirring blade can be improved. [Industrial applicability]

[0036] The stirring device of the present invention can be widely applied to the field of stirring devices that improve cleaning performance. [Explanation of symbols]
