Abstract

PURPOSE:To make measuring errors hard to occur with a simple operation, by comparing a measured value, obtained with a weight measuring section, with an input value inputted to a set input section to output an opening or closing signal to an opening/closing valve when the measured value is below the input value or when it reaches the value. CONSTITUTION:A liquid tank 14 is arranged above an electronic scale 12 and an solenoid valve 16 as an opening/closing valve to control the dropping and injection of a lead acetate solution 7 in an injection tube 15 near an outlet section thereof 15; the opening or closing operation of the solenoid valve 16 is performed by an opening or closing signal from an opening/closing valve control section 17. Then, the opening/closing valve control section 17 compares a measured value, obtained with the electronic scale 12, with an input value inputted into a set input section and transmits an opening signal to the solenoid valve 16 when the measured value is below the input value while it transmits a closing signal thereto 16 when it reaches the input value. Thus, the lead acetate solution 7 is supplied at a specified rate to a brei 3 in a polyester cup 13 from the liquid tank 14.

Description

Detailed Description of the Invention (Field of Application on Jvl) The present invention relates to an automatic constant RL injection device for t-ma solution, and is particularly suitable for analyzing sugar content in roots.
! This is related to the automatic setting h' suitable for injecting a lead solution (or a solution replacing it) at a constant ratio.

[Conventional technique] Bee 1 - For sugar analysis of grudges, beet root braai (
Drunk on daikon (white radish)? (1 solution (the sentence is from the song)
7 FI solution) at a fixed ratio to make a mixed solution, stirred the mixed solution, IT-filtered it, took out a part of it, and measured the extracted sugar (δ is iii) using a polarimeter according to A method for determining the sugar content of

In order to obtain accurate sugar content analysis of beet roots, it is necessary to keep the injection ratio of lead acetate solution (or other solution) to beet braai constant. The ratio of roots to Bri 1 is 6.835 (in the case of other solutions, the seed strength of Wi solution of b() is adjusted at a constant ratio 41).

).

By the way, this sugar content analysis of beet roots requires taking sugar samples about 600 times a day and continuing this for about 5 months. Therefore, conventionally, 1: 1111 people use a 51 measurement device that uses etc. to measure 3.1 shi M lead solution 6.835 for Bee 1 to root braai 1 J: sea urchin n 1 is being carried out.

Figure 3 (well, this conventional measuring device is shown in Fig. 11'), so 51 objects to be measured are placed in a box-shaped container 1 at the desired SF side ratio (in this case, #acid lead to 1 beet root braai). solution 6.835
) C Dispensing top ■ 1 person Place a balance and place one plate 2.
After placing a predetermined amount (for example, 26 pieces) of braai 3 on the medicine package paper on the other side 2b, turn on the switch 5 on the polycup 4 on the other side 2b, and open the solenoid valve 6 linked to this to open the tank (1! As the lead acetate solution 7 is gradually injected from the container 1, a photo hill 8 installed on the inner surface of the container 1 detects the passage of the descending balance plate 2C through a predetermined point, and the predetermined injected product (
For example, 177.7 bi) is measured, and the f A1-L! The detection signal from the valve 8 closes the solenoid valve 6 and stops the injection.
At the same time, the switch 5 is turned off.

Fine adjustment of the injected lead acetate solution 7 is made by connecting the other end of the chain 9 attached to one end of the 4I:1 part 2d of the upper balance 2 to the disc 10.
The small center of the chain 9 is moved by the rotation of the disc 10.

[Problems that inventions are struggling to solve]

By the way, the adjustment of the ratio for this device is done using Bligh 3.
When the acid-resistant lead solution 7 was injected, another precision balance was used to measure the weight of the lead 3 and the 114 of the lead acetate solution 7 at 51.
Therefore, check whether the ratio is 1:6.835, rotate the disk 10 from this bundle, make slight adjustments, and then check the ratio in the same way. It is difficult and requires skill.

In addition, due to the expansion of the JS due to temperature, there will be a slight deviation in the opening as time progresses, so it is important to make adjustments at fixed times ft1 (at least 3 times a day, in the morning, noon and evening). However, as mentioned above, if the measurements were to be taken 600 times a day, it would be a considerable amount of work.

In addition, Bly 3 and lead acetate solution 7 measured as < n1 as described above.
This means that you will need to transfer it to another container to make a mixed solution, but in this case, one drop of Bligh 3 will be placed on the mulberry paper, and one drop of the lead acetate solution 7 will be placed in the poly cup 4, leaving 61 remaining. , a considerable difference occurs between repeated measurements.

Therefore, in the present invention, the operation is carried out in the blood, and if n1 is measured, i;

Incidentally, in this embodiment, one bottle of lead acetate solution was used for 11 people in J3 for braai, but it is of course applicable to other solutions as well.

Next, the operation of the self-sustaining suspension injection device is shown in Figure 2.
The explanation will be based on -1~.

First, create ratios, coefficients, and tables with initial settings (step ■).
