Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention extracts the extract from the sample liquid in the sample liquid container. Concerning shakers for shaking dishes, especially shakers equipped with a fixed position stop device. Ru.

0002

[Conventional technology]

Conventionally, a sample solution, such as a solution of benzene and water, was placed in a shaker and shaken to determine the specific gravity. The liquid is separated based on the difference in

0003

[Problem that the idea aims to solve]

The above conventional method is inefficient, takes a lot of time, and is not suitable for large-volume extraction processing. The problem is that it does not.

0004

[Means to solve the problem]

In order to solve the above-mentioned problems, the shaker of the present invention is designed to finish shaking as shown in Figure 1. A plurality of sample liquid containers 16 were held on the drive shaft 5 of the main rotary machine 13, which stopped at certain times. An eccentric cam 18 for shaking the holding part 17 is connected, and a rotation transmission mechanism is connected to the drive shaft 5. 19 to switch between the clutch 10 and the main rotary machine 13, which operate at the end of shaking. A rotating auxiliary rotary machine 11 to be driven is connected, and the drive shaft 5 has a transparent hole 20. The rotating plate 6 is fixed, and the light source 9A constituting the photosensor 9 is inserted through the transparent hole 20. Light receiving parts 9B for stopping the auxiliary rotary machine are arranged facing each other.

[0005]

[Effect]

When the main rotating machine 13 is rotated and the eccentric cam 18 connected to its drive shaft 5 is rotated, The holding part 17 holding a plurality of sample liquid containers 16 is shaken, and each sample liquid volume is The sample liquid in the vessel 16 will be extracted. Clutch 10 operates during shaking. No, the auxiliary rotary machine 11 is idle but stopped.

[0006] When the shaking is finished, the main rotating machine 13 stops, the clutch 10 is activated, and the auxiliary The rotating machine 11 will be rotated, and the rotation will be caused by the clutch 10 and the rotation transmission mechanism. The signal is transmitted to the drive shaft 5 via 19, and the rotary plate 6 is rotated. photoset The light emitted from the light source 9A of the sensor 9 passes through the transmission hole 20 of the rotating plate 6 and reaches the light receiving part 9B. The electric signal disables the clutch 10, and the auxiliary rotary machine 11 will be suspended.

[0007] As a result, the holding part 17 is stopped at a fixed position, and the holding part 17 is After finishing, no matter what position it is in, it will be detected by the photosensor 9 when it reaches the fixed position. The clutch 10 is deactivated by the electric signal detected by the electric signal, and the auxiliary rotary machine 11 is stopped. The holding part 17 and, by extension, the sample liquid container 16 are held in the correct position. It will be suspended.

【Example】

Fig. 1(A) is an explanatory diagram showing the configuration of one embodiment of the shaking machine of the present invention, and Fig. 1(B) is an explanatory diagram showing the configuration of one embodiment of the shaking machine of the present invention. FIG. In Figure 1, 13 is at the end of shaking. The main motor to be stopped, 5, is its drive shaft. This drive shaft 5 contains a large number of sample liquids. An eccentric cam 18 is attached to shake the holding part 17 holding the container 16. .

[0009] This holding part 17 is provided in the circumferential direction into which a large number of sample liquid containers 16 are inserted. A rack top plate having a large number of holding holes 17A and a rubber plate 15 for dampening vibrations. 1, the rack lower plate 2 that supports the sample liquid container 16, and each holding hole 17A. A cork retaining plate 3 having retaining holes 17B in the portion thereof and fixed to the upper surface of the rack lower plate 2. It becomes more.

0010 The drive shaft 5 of the main motor 13 is connected to the drive shaft 5 via a rotation transmission mechanism 19 that operates at the end of shaking. A clutch 10 and an auxiliary motor 11 that switch and drive the main motor 13 are connected. ing. The rotation transmission mechanism 19 includes a toothed pulley 7 fixed to the drive shaft 5 and a clutch. A toothed pulley 8 fixed to the shaft on the side and a timing suspended between both pulleys 7 and 8. It consists of a belt 14. 10 is a micro clutch, and 12 is a gear.

[0011] A rotary plate 6 having a transparent hole 20 is fixed to the drive shaft 5. The light source 9A constituting the photosensor 9 and the light receiving part 9B for stopping the auxiliary motor are facing each other. It is located. Additionally, the clutch 10, auxiliary motor 11, main motor 13, etc. are controlled. The control section for this is omitted.

0012 In the embodiment with the above configuration, the bias motor rotates the main motor 13 and is connected to the drive shaft 5. When the center cam 18 is rotated, the holding part 17 holding a large number of sample liquid containers 16 is rotated around the shaft. The sample liquid in each sample liquid container 16 is shaken with a core deflection of 5 mm from the center. will be stirred. During shaking, the clutch 10 does not operate and the auxiliary motor 11 is idling but has stopped.

[0013] When the shaking is finished, the main motor 3 is stopped, the clutch 10 is activated, and the auxiliary motor is activated. The motor 11 is rotated, and the rotation is transmitted through the clutch 10 and the rotation transmission mechanism 1. The signal is transmitted to the drive shaft 5 via 9, and the rotary plate 6 is rotated. photo sensor The light emitted from the light source 9A of the sensor 9 passes through the transmission hole 20 of the rotary plate 6 and reaches the light receiving part 9B. The light is received, and the electric signal causes the clutch 10 to become inoperative and the auxiliary motor 11 to be activated. It will be suspended.

[0014] As a result, the holding part 17 is stopped at a fixed position, and the holding part 17 is After the end, the electrical signal detected by the photosensor 9 at any position This causes the clutch 10 to become inoperable and the auxiliary motor 11 to stop, thus preventing maintenance. The holding part 17 and, by extension, the sample liquid container 16 are accurately stopped at a fixed position. .

[0015] In the case of a normal flash mixer, the main motor 13 is a Kumatori motor or A series motor is used, but it suffers from vibration due to voltage fluctuations and the size of the load. Since the rotation speed changes, a constant torque motor is used and a feedback circuit is used to control the speed. The speed fluctuation rate can be kept small and stable by this function.

[0016] A fluoro rubber plate 15 is placed on the bottom surface of the rack top plate 1, and a cork plate is placed on the top surface of the rack bottom plate 2. By attaching the retainer plate 3, it is possible to hold the container and prevent noise during shaking. Ru.

[0017]

[Effect of the idea]

As described above, according to the present invention, the holding section 1 holding a plurality of sample liquid containers 16 7 can be shaken, improving efficiency and shortening the required time. It is possible to provide a shaker suitable for separating large amounts of liquid.
