Description

[Detailed Description of the Invention] Industrial Application Field This invention provides a double rotary table in which a small rotary table that rotates on its own axis is installed on a large rotary table that revolves, and a container containing a processed material is placed on the small rotary table. Regarding.

Conventional technology Conventionally, for example, in the tissue culture of plants and animals, constant temperature and humidity chambers for culturing cells and tissues, and sunlight constant temperature chambers (artificial climate chambers) attached to lighting devices to provide photosynthesis have been used. In this case, the sample
Physical conditions such as light, temperature, humidity, and ventilation must be provided evenly to objects.

Problems to be Solved by the Invention For this reason, various devices such as rotating tables, rotary culture devices, shaking culture devices, etc. have been provided to stir the processed material in the container. It is extremely difficult to maintain the same conditions at the inner periphery of the container, and when there is a large amount of material to be processed, there is a shadow area, which causes uneven circulation of temperature and humidity inside the container. It was hot too.

An object of the present invention is to provide an apparatus which eliminates the drawbacks of the various conventional apparatuses as described above, and which enables the processed material stored in the container to undergo substantially uniform physical processing.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention includes a large rotary table and a plurality of small rotary tables installed on a tiltable pedestal, and a drive member for the large rotary table and a large rotary table. The present invention is characterized by providing an interlocking mechanism that rotates the small rotary table as the table rotates.

Effect This invention is as described above, and when the large rotary table is rotated by the drive member after the mount is tilted at a desired angle, the small rotary table rotates while revolving around the rotation table and is placed on it. The processed material in the container will be stirred.

Embodiment 1 shows a hollow cylindrical frame. A large rotary table 3 is attached to the top of a rotating shaft 2 established in a support frame 4 at approximately the center of the frame 1. A motor 5 is attached to the support frame 4. The driving force of the motor 5 is transmitted to the rotating shaft 2 via a bevel gear set 6. The large rotary table 3 includes a plurality of (four in this embodiment) small rotary tables 7 at approximately equal intervals in the circumferential direction.
A shaft 8 is pivotally supported, and a pulley 9 is attached to the lower end of the shaft 8. Further, a plurality of container holders 13 are attached to the surface of the small rotary table 7, and the holders 13 are formed of a plurality of spring members.

A fixed pulley 11 is attached to the upper part of the support frame 4 via a support rod 10, and the rotating shaft 2 is connected to this pulley 1.
1 in a rotatable manner.

A base plate 16 is pivotally attached to one side of the bottom surface of the pedestal 1 via a hinge 15.
A plurality of wavy protrusions 17 are provided on the side opposite to 5. A proximal end portion of a locking rod 18 whose distal end portion can be freely engaged with and detached from a protrusion 17 is pivotally supported on the bottom surface of the pedestal 1.

To explain the use of the above-mentioned device in a sunlight incubator, as shown in FIG. Holding the container 20 with the holder 13 of 7, the motor 5
operate. As a result of this operation, the large rotary table 3 is rotated by the rotary shaft 2 via the gear set 6 in the direction of arrow A in FIG.

Due to this rotation, the small rotary table 7 also revolves in the same direction, and the pulley 9, which is integrally attached to it via the shaft 8, is moved by the belt 12 suspended between the fixed pulley 11 as shown by arrow B. In this way, the small rotary table 9 rotates several times during one rotation of the large rotary table 3.

In this way, the container 20 moves within the illumination device 21 together with the small rotary table 7 while orbiting and rotating, so that the sample in the container 20 is effectively stirred and at the same time all of the contents of the container 20 are Since the surfaces of the lights face the illumination device 21 alternately, light is received uniformly regardless of whether the front or back sides are the same.

This condition applies not only to lighting work, but also to heating,
Exactly the same phenomenon occurs when humidity is added.

Furthermore, in this case, when the pedestal 1 is tilted relative to the base plate 16 around the hinge 15 as shown in FIG. 7 is in a tilted state. Therefore, if the movement is performed as described above, the necessary operations such as stirring and light reception as described above can be performed more effectively.

It goes without saying that the present invention may have other embodiments other than the above-described embodiments. For example, the fixed pulley 11 may be a rotating pulley like the other pulleys 9, or a bevel gear set or a pulley may be used. The transmission mechanism using a belt and a belt may be replaced with another gear transmission mechanism, and the small rotary table 7 may have multiple layers instead of just one layer. It may be a mechanism, and the holder 13 may also be detachable so that it can be replaced depending on the size of the container 20.

Effects of the Invention This invention is as described above, in which a plurality of small rotary tables that revolve together with the large rotary table but also rotate at the same time are attached to the large rotary table, so that the entire table can be set to any tilted position, and the rotation thereof Since this is performed by a drive member and an interlocking mechanism, the processed material in the container mounted on the small rotary table moves three-dimensionally and moves between the inner and outer surfaces of the container. It circulates and moves, creating an effective stirring action, and it is possible to uniformly apply the action to the processed material by physical processing members located outside, especially for culturing and analysis that require temperature, humidity, and illuminance. ,
It has the effect of being useful for processing such as inspections, and small-scale drying, painting, spraying, disinfection work, etc.
