Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a thermo-hygrostat for a system for automatically storing a culture tray used for cell culture in the bioscience field in a thermo-hygrostat such as an incubator. It relates to the structure of the tray stocker installed inside.

(Prior Art) As a conventional technology, for example, there is a constant temperature and humidity apparatus disclosed in Japanese Utility Model Publication No. 61-182300.

(Problems to be Solved by the Invention) In this type of conventional device, a drive system mechanism including a motor is arranged in a constant temperature and humidity chamber as in the device disclosed in the above publication. The constant temperature and humidity are set at 90% humidity in order to culture the cells.
It maintains a high humidity environment of at least%, which is a bad environment for a drive mechanism such as a motor. Therefore, it is necessary to store the motor in a housing that is sealed by a gasket, etc., and the capacity for storing the trays in the constant temperature and humidity chamber is reduced by the space of the housing, and the number of trays that can be stored is reduced. was there. Further, since the housing is housed in the tank and the motor and the like are housed in the housing, there is a problem that maintenance is difficult when the drive system such as the motor fails.

(Means for Solving Problems) FIG. 1 is a specific example of the present invention. 1 is an incubator body, 2 is an incubator door, 3 is a tray stock,
Reference numeral 4 is a base, 5 is a motor, 6 is an encoder, 7 is a coupling, and 8 is a timing belt. The tray stock 3 is rotatably held on the base 4 by a thrust bearing or the like about a vertical axis, and the central axis penetrates the incubator housing and reaches the upper part of the incubator body.
It is connected to the shaft of the motor 5 by a coupling 7. The rotation of the motor 5 is transmitted to the encoder 6 by the timing belt 8.

The rotatable tray stock 3 provided inside the housing
The tray storage discs 9 are arranged at regular intervals in the rotation axis direction, and a plurality of notches 10 are provided on the outer circumference of each of the tray storage discs 9 at regular intervals in the circumferential direction. The notches 10 provided in the plurality of tray storage disks are arranged in the axial direction to form an axial passage.

(Operation) Since the structure is as shown in FIG. 1, it is not necessary to sacrifice space for the drive mechanism. In addition, since it is not necessary to place a drive mechanism in a high-humidity thermostat, the possibility of failure is reduced. Even if a failure occurs, maintenance is easy because the drive mechanism is located outside the constant temperature bath. Furthermore, because it is not necessary to lead the wiring of the electric system into the constant temperature bath,
There is no need to provide holes for wiring or the like on the outer wall of the constant temperature and constant humidity chamber, and the structure of the constant temperature and constant humidity chamber is simplified. Further, since the motor, which is a heat source, goes out of the constant temperature and humidity chamber and the structure inside the chamber is rotationally symmetric, the temperature distribution in the chamber tends to be uniform.

Further, since each of the tray storage disks 9 is provided with a plurality of cutout portions 10, and the cutout portions 10 provided in the plurality of tray storage disks are arranged in the axial direction,
When introducing air under the optimum conditions for cell culture into the tank, the air passes through the passage formed by the notches 10 arranged in the axial direction and is divided into a plurality of tray storage disks 9, There is no difference in culture conditions depending on the axial position of the tray storage disk, and the culture is uniform.

(Example) The description is omitted because it is the same as the specific example.

(Effects of the Invention) As described above, in the present invention, the notches provided in the plurality of trays having a specific shape have a specific positional relationship, that is, a position where the notches are arranged in the axial direction. Therefore, each notch part forms an axial passage as a whole, and the optimal air for cell culture is evenly distributed between the plurality of tray storage disks through the passage. be able to. In addition, a drive mechanism is installed outside the constant temperature and humidity chamber to drive a tray stocker rotatably held around a vertical axis in the chamber to move a desired tray to the door of the constant temperature and humidity chamber. Due to the structure, a large number of trays can be held, and the maintainability of the apparatus itself is improved.
