Description

[Detailed Description of the Invention] The present invention relates to a shaking culture machine capable of horizontal reciprocating and rotational shaking.

In recent years, technology using microorganisms has been attracting attention, and there is a demand for a shaking culture machine used for culturing these microorganisms to have multiple functions.

In particular, there is a need for a shaking culture machine that is capable of horizontal reciprocating shaking and rotary shaking with a single device, allows setting of various culture conditions, and is easy to operate.

Conventionally, as a culture machine capable of horizontal reciprocating and rotational shaking, the one described in Japanese Patent Publication No. 56-46394 is known, but this one has stays attached to the rotating body and the related reciprocating mechanism. By providing a metal fitting and attaching and fixing the panel mounting stay of the panel to which the culture container (mounting frame) is attached to the stay mounting bracket provided on the rotating body, the panel and the culture container mounting frame can be rotated together with the panel. In addition, by attaching and fixing the panel mounting stay to the stay mounting bracket provided on the reciprocating mechanism, the panel and the culture vessel mounting frame integrally therewith are horizontally reciprocated.

Therefore, to switch between horizontal reciprocating shaking and rotary shaking, remove the culture vessel mounting frame from the panel, then remove the panel mounting stay from the rotating body or the stay mounting bracket of the reciprocating mechanism, and then reinstall the panel. requires the troublesome procedure of attaching the stay to the reciprocating mechanism or the stay mounting bracket of the rotating body and reattaching the culture container mounting frame to the panel, and it takes a lot of effort to switch between horizontal reciprocating shaking and rotary shaking. In addition, there is a lot of time loss due to switching operations, and it is therefore difficult to set culture conditions during culture, such as changing from horizontal reciprocating shaking culture to rotary shaking culture.

Furthermore, this shaking culture machine has problems such as a relatively complicated horizontal shaking mechanism (reciprocating mechanism).

The present invention was developed in view of the above circumstances, and has multi-functionality that enables horizontal reciprocating shaking and rotary shaking, and allows for easy setting of various culture shaking conditions. To provide a shaking culture machine which can be easily switched with one touch, does not require troublesome operations, has a relatively simple structure, and can be manufactured at low cost.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a base, and a motor 2 is disposed on one end of the base 1 in the length direction. 4 is installed.

Although not shown, the motor 2 is provided with a speed change handle, and by operating this speed change handle,
The rotation speed of the motor 2 can be changed.

A first bearing body 5 is disposed on the base 1, and a pair of connecting rotary shafts 7 and a first rotary shaft 8, which are detachably connected to each other through a clutch 6, are disposed within the bearing body 5, respectively. Rotatably supported.

The lower end of one of the connecting rotary shafts 7 protrudes into the base 1,
A two-stage pulley 9 is fixed to the tip thereof, and a belt 10 is stretched between one pulley 9a of the two-stage pulley 9 and the pulley 4 of the shaft 3 of the motor 2.

Further, the upper end portion of the other first rotating shaft 8 protrudes above the bearing body 5, and a first rotating disk (first rotating body) 11 is fixed to the tip thereof.

Therefore, when the motor 2 is driven in a state where both rotating shafts 7 and 8 are connected to each other via the clutch 6, the rotation of the shaft 3 is controlled via the pulley 4, the belt 10, and the two-stage pulley 9. The first rotating disk 11 rotates together with the rotation of the two rotating shafts 7 and 8, and the two rotating shafts 7 and 8 are separated from each other by the operation of the clutch 6. When the motor 2 is driven in this state, the first rotating disk 11 is stopped.

A first eccentric shaft 12 is rotatably provided on the first rotating disk 11 so as to be eccentric to the first rotating shaft 8, and the tip of the first eccentric shaft 12 is located at one end of the crank arm 13. Rotatably mounted.

Although not shown, the upper end of the eccentric shaft 12 is rotatably supported by a movable body disposed in a long hole drilled in one end of the crank arm 13 so as to be movable in the longitudinal direction. The movable body is fixed at a predetermined position by a fixing bolt.

In addition, oil stands 1 are provided at each of the four corners of the base 1.
4.14 is fixed, and as shown in FIG. (
A lower mount) 17 is fixed, and the upper end of a pin 19 is rotatably attached to a support plate 18 fixed to the lower surface of this panel 17. It is rotatably fitted into a hole provided on the end side.

Therefore, as the first rotary disk 11 rotates, its motion is transmitted to the panel (lower frame) 17 via the first eccentric shaft 12, crank arm 13, and pin 19, and the panel 1
Since the sliding support columns 16, 16 fixed to 7 are slidably attached to the sliding shaft 15, the panel 17 can reciprocate in the axial direction of the sliding shaft 15, that is, in the left-right direction in FIG. It is supposed to be done.

Further, a second bearing body 20 is disposed on the base 1 in line with the first bearing body 5, and a connecting rotary unit is detachably connected to the second bearing body 20 via a clutch 21. A shaft 22 and a second rotating shaft 23 are each rotatably supported.

The lower end of one of the connecting rotary shafts 22 protrudes into the base 1, and a pulley 24 is fixed to its tip, and a belt 25 is connected between this pulley 24 and the other pulley 9b of the two-stage pulley 9. It is stretched.

Further, the upper end portion of the other second rotating shaft 23 projects above the bearing body 5, and a second rotating disk (second rotating body) 26 is provided at the tip thereof.
is fixed.

Therefore, when the motor 2 is driven with both rotating shafts 22 and 23 connected to each other via the clutch 21, the rotation of the shaft 3 is caused by the pulley 4, belt 10,
It is transmitted to both rotating shafts 22.23 via the two-stage pulley 9, belt 25, and pulley 24, and the second rotating disk 26 rotates together with the rotation of both rotating shafts 22.23, and the clutch 2
When the motor 2 is driven in a state where both rotating shafts 7°8 are separated from each other by the operation in step 1, the second rotating disk 2
6 is stopped.

On the second rotating disk (second rotating body) 26, the second
A second eccentric shaft 27 is rotatably provided eccentrically from the rotating shaft 23, and an upper end portion of the second eccentric shaft 27 projects above the frame-shaped panel 17.

Further, at the four corners of the panel (lower mount) 17, there are oil stands 28.28 having almost the same structure as the oil stand 14.14 on the base 1, with the axial direction of the sliding axis being on the base 1.
The upper oil studs 14 and 14 are each fixed in a direction perpendicular to the axial direction of the sliding shaft 15, and the sliding support columns 2 of these oil stands 28 and 28 are fixed respectively.
On 9.29, an oil stand 14.14 was placed on the base 1.
And an oil stand 30° 30 having almost the same configuration as the oil stand 28.28 on the panel 17 has an axial direction of its sliding shaft relative to the axial direction of the sliding shaft of the oil stand 28.28 on the panel 17. They are each fixed in a perpendicular direction (in the same direction as the axial direction of the sliding shafts 15 of the oil stands 14, 14 on the base 1).

And the sliding support column 3 of the oil stand 30.30
A panel (upper mount) 33 to which a culture container container 32 is attached is fixed to 1 and 31, and the tip of the second eccentric shaft 27 is rotatable and removable on a support plate 34 fixed to the lower surface of this panel 33. is attached to.

Therefore, due to the rotation of the second rotating disk 26, its motion is transmitted to the panel 33 via the second eccentric shaft, and the panel 3
A sliding support column 31.31 fixed to the oil stand 30, 30 is slidably attached to a sliding shaft in the oil stand 30, 30, and a sliding support column 29, 29 fixed to the oil stand 30. Oil stand 28.28 sliding in the direction perpendicular to the sliding direction of the sliding shaft inside the oil stand 30, 30
The panels 33 can be rotated by being fixed to sliding shafts inside the panels.

Although not shown, the oil station 14.1
4, 28, 28, 30, and 30 are each provided with a stopper for stopping the sliding of the sliding shaft.

Further, although the arrangement of the first and second eccentric shafts 12, 27 with respect to the first and second rotating disks 11, 26 described above is schematically shown in FIG. 1, it is specifically shown in FIG. As shown.

That is, a box 35 is fixed on the rotary disk 11, and an adjustment screw 36 is connected within this box 35.
A movable body 37 that moves forward and backward along the radial direction of the rotary disk 11 by forward and reverse rotation operations of 6 is provided, and the eccentric shaft 12 is rotatably supported on the movable body 37.

In addition, in the figure, 38 is a fixing bolt, 39 is an amplitude indicator needle, and 40
is a scale plate.

Therefore, by operating the adjustment screw 36, the movable body 37 and the eccentric shaft 12 are moved in the radial direction of the disk 11, and the distance between the center of the disk 11 and the eccentric shaft 12 is adjusted to a desired distance. This allows the amplitude of the panel 17 to be adjusted to a desired value.

Although the above description is about the arrangement of the first eccentric shaft 12 with respect to the first rotating disk 10, the arrangement of the second eccentric shaft 27 with respect to the second rotating disk 26 is also the same.

Since the shaking culture apparatus shown in FIGS. 1 to 3 has the above configuration, by operating the clutches 6 and 21, the connecting rotating shaft 7 and the first rotating shaft 8 are connected, and the connecting rotating shaft 2
2 and the second rotating shaft 23 are separated and the motor 2 is driven in this state, the rotation of the shaft 3 is transferred to the connecting rotating shaft 7 and the first rotating shaft 8 via the pulley 4, the belt 10, and the two-stage boot IJ9. The first rotating disk 11 rotates together with the two rotating shafts 7 and 8.

Therefore, this causes the lower panel 17 to reciprocate from side to side in FIG. The sliding support columns 31, 31 and the upper panel 33 reciprocate together with the lower panel 17.

One of the connecting rotating shafts 22 of the second bearing body 2.0 rotates, while the other second rotating shaft 23 rotates.
Since it is separated from the second rotating disk 26, it does not rotate, so the second rotating disk 26 does not rotate.

Therefore, the upper panel 33 does not receive any movement from the second rotating disk 26, so it only reciprocates from side to side together with the lower panel 17, and is therefore attached to the upper panel 33. The culture container container 32 thus placed is reciprocated from side to side to perform horizontal reciprocating shaking culture.

In this case, adjust the rotation speed of motor 2 and adjust screw 3.
6 to adjust the distance between the center of the disc 11 and the eccentric shaft 12, the reciprocating cycle and amplitude of the storage body 32 can be made as desired.

In this case, if necessary, the stopper may be used to stop the sliding of the sliding shaft in the oil stand 28, 28, 30, 30 to prevent its displacement, or the support plate 34 and the second eccentric By separating the shaft from the panel 3
3 degrees of freedom can be increased.

Further, by operating the clutches 6 and 21, the connecting rotating shaft 22 and the second rotating shaft 23 are connected, and the connecting rotating shaft 7 and the first rotating shaft 8 are disconnected, and the motor 2 is driven in this state. , the rotation of the shaft 3 is transmitted via the pulley 4, the belt 10, the two-stage pulley 9, the belt 25, and the pulley 24 to the connecting rotation shaft 22 and the second rotation shaft 23, The two-rotation disk 26 rotates.

Therefore, this causes the upper panel 33 to rotate.

One of the connecting rotary shafts 7 of the first bearing body 5 rotates, but the other first rotary shaft 8 does not rotate because it is separated from the connecting rotary shaft 7. Therefore, the first rotary disk 11 It doesn't rotate.

Therefore, since the movement from the first rotating disk 11, that is, the movement of the lower panel 17, is not transmitted to the upper panel 33, the upper panel 33 is rotated by the movement of the second rotating disk 26. Therefore, the culture container container 32 attached to the upper panel 33 is rotated, and rotational shaking culture is performed.

In this case, by adjusting the rotation speed of the motor 2 and adjusting the distance between the center of the disk 26 and the eccentric shaft 27 using an adjustment screw, the rotation cycle and rotation radius of the housing 32 can be made as desired. I can do it.

In this case, if necessary, the stopper can stop the sliding movement of the sliding shafts in the oil stands 14, 14 to prevent their displacement.

Furthermore, in the above device, by operating the clutches 6 and 21, the connecting rotating shaft 7 and the first rotating shaft 8 and the connecting rotating shaft 22 and the second rotating shaft 23 are connected, respectively,
By driving the motor 2 in this state, the reciprocating movement of the lower panel 17 and the rotation of the upper panel 33 are combined to rotate the culture container container 32 in a complicated trajectory such as an ellipse. You can also do it.

Therefore, according to the shaking device described above, the clutch 6.21
By operating the culture container container 32, it is possible to reciprocate or rotate the culture container container 32 with a single touch, and it is possible to switch between horizontal reciprocating shaking and rotational shaking while the container 32 is placed on the container. , the number of cycles, and the amplitude can be easily adjusted and desired shaking conditions can be set very easily.

Furthermore, by using not only a flask type culture container container 32 but also a test tube type type, it is also possible to carry out test tube shaking culture.

In the embodiment described above, when transmitting rotation from the shaft 3 of the motor 2 to the pulley 24 attached to the connecting rotating shaft 22 of the second bearing body 20, the connecting rotating shaft 7 of the first bearing body 5 is Although the step pulley 9 is attached and the rotation is transmitted via the two-step pulley 9, the present invention is not limited to this. Also, the connecting rotating shaft 7 of the first bearing body 5 and the connecting rotating shaft 2 of the second bearing body 20
2 may be rotated by separate motors.

Furthermore, when transmitting rotation from the shaft of the motor to the first rotating disk 11 and the second rotating disk 26, various pulleys, gears, etc. are combined, and a known appropriate speed change mechanism or direction changing mechanism is employed. It is also possible to control the rotation speed and rotation direction of both discs 11.26.

Furthermore, the rotation mechanism of both discs 11 and 26, the reciprocating mechanism of the lower panel 17, the rotation mechanism of the upper panel 33, or the oil stand, sliding shaft, and sliding support shown in FIGS. 1 and 2. The translational and rotational guiding mechanism consisting of the body is not limited to the illustrated embodiment, and other configurations may be modified in various ways without departing from the gist of the present invention.

As explained above, the shaking culture apparatus of the present invention is driven by a driving body such as a motor, and a first rotating shaft is connected to a first rotating shaft that is detachably connected to this driving body via a clutch.
A rotating body is attached, and a lower mount is attached via a crank arm to a first eccentric shaft provided on the first rotating body eccentrically from the first rotating shaft, and the lower mount is attached to the mount so that it moves linearly in a predetermined direction. A second rotary body is installed on a second rotary shaft which is provided with a linear motion induction mechanism for guiding and is detachably connected to a driving body such as a motor via a clutch,
A culture container container or a mounting body for the container is attached to a second eccentric shaft provided on the rotating body eccentrically from the second rotation shaft, and the culture container container or the mounting body rotates together with the rotation of the second eccentric shaft. In addition, a rotation guiding mechanism is provided on the pedestal to connect the driving body and the first rotating shaft by operating the clutch, and the pedestal is rotated by the rotation of the first rotating body. reciprocate in a predetermined direction,
While integrally reciprocating the culture container container or the attachment body of the container, the drive body and the second rotating shaft are connected by operating the clutch, and the rotation of the second rotor causes the culture container container to move back and forth. Alternatively, by configuring the mounting body of the container to be rotated, switching between horizontal reciprocating shaking and rotary shaking can be performed very easily by simply switching the clutch, so to speak, with one touch, and no troublesome operations are required. It is also possible to switch between reciprocating motion and rotation during culture, making it possible to easily set various culture shaking conditions.

Furthermore, the device of the present invention is capable of horizontal reciprocating shaking and rotary shaking as described above, has multiple functions, and has the advantage of being relatively simple in structure and inexpensive to manufacture.
