This is an automatic liquid measuring and sampling device that can accurately and quickly collect the required amount of liquid, or mix and dilute two liquids in the required ratio, and mainly handles relatively small amounts of liquid such as for experimental vehicles. sometimes used.
本出願人はさきに光液面計を応用した自動液体計量採取
装置（特開昭５３−２７４５３及び特開昭５３−５５１
９１）を提案した。The present applicant previously developed an automatic liquid measuring and sampling device using an optical liquid level gauge (Japanese Patent Application Laid-Open Nos. 53-27453 and 53-551).
91) was proposed.
しかし上記の自動液体計量採取装置では計量槽は１個で
あり、１種類の液を所要量採取できるに過ぎなかった。However, the automatic liquid measuring and sampling device described above has only one measuring tank, and can only collect the required amount of one type of liquid.
また採取量は正確であったが、採取の速度が遅いことが
欠点であった。Although the amount collected was accurate, the drawback was that the sampling speed was slow.
また一般に市販されているこの種の装置では採取速度の
比較的速いものもあるが、光液面計方式に比して正確さ
に欠けたり、比較的採取量が多い場合には不向きであっ
た。Additionally, although some commercially available devices of this kind have relatively fast sampling speeds, they lack accuracy compared to the optical liquid level meter method, and are not suitable for relatively large amounts of sample. .
本発明は比較的大容量の採取に向いていて、かつ従来の
装置が持つこれらの欠点を解消したもので、計量槽を２

, (BL) Two measuring tanks (A) l with 10 inserted
, (B) 6 are provided, and the electronic circuit 11 opens and closes four electromagnetic valves 2.3.7.8 to discharge the liquid from the storage tank 13 to the required amount set between the levels of the tips of the glass rods. This is an automatic liquid weighing and sampling device that allows liquid to be sampled into a container 12, but at the same time each measuring tank (A) 1,
(B) In 6, the number of times N (hereinafter referred to as N) of liquid flowing in from the storage tank 13 and flowing out into the container 12 can be controlled by the electronic circuit 11, respectively. Further, as shown in FIG. 2, a storage tank 14 is further provided, and each storage tank 13
．． If two types of liquids are placed in the container 14, the two liquids can be mixed and diluted in different required proportions.
さらに本発明の実施の態様について詳しく述べる。Further, embodiments of the present invention will be described in detail.
（ａ）計量槽の容量に比較して採取すべき液量（以下所
要量とする）が大きい場合
第３図に示すように、従来の１個の計量槽の場合は所要
量を採取するのに、何回も採取操作を行わなければなら
なく、時間を要したが、本発明では２個の計量槽である
ので、計量槽の容量が同一であれば、採取時間は半分に
なる。オなイっち２個の計量槽の光液面計による液量の
設定を同一にしておき、計量槽への液の流入・流出回数
Ｎを選ぶことにより（設定された液量）ＸＮで希望する
採取量が正確かつ迅速に得られる。(a) When the amount of liquid to be sampled (hereinafter referred to as the "required amount") is large compared to the capacity of the measuring tank. However, since there are two measuring tanks in the present invention, if the capacity of the measuring tanks is the same, the sampling time is halved. By setting the liquid volume using the optical liquid level gauges of the two measuring tanks the same, and selecting the number of times N for liquid to flow into and out of the measuring tank (the set liquid volume), The desired amount of sample can be obtained accurately and quickly.
例えば計量槽の液量の設定量を１００ｍ１とし、所要量
を５００ｍ１とすれば、計量槽（Ａ）のＮを３、計量槽
（Ｂ）のＮを２と選んでおけば電子回路により容易に目
的が達せられる。For example, if the set amount of liquid in the measuring tank is 100ml and the required amount is 500ml, if the N of the measuring tank (A) is selected as 3 and the N of the measuring tank (B) as 2, the electronic circuit can easily be used. The purpose is achieved.
（ｂ）所要量が大きく、はんばまたはこきざみの場合従
来の１個の計量槽の場合、例えば計量槽の容量の１５倍
の液を採取したい時は容景一杯の量をまず採取し、次に
一方のガラスロッドを移動して残りの量を採取せねばな
らなく、これは手数と時間を要すこととなる。また所要
量が大きく、こきざみの量の場合の液の採取はさらに手
数と時間を要する。(b) If the required amount is large, such as Hanba or Kokizami In the case of conventional one measuring tank, for example, if you want to collect 15 times the capacity of the measuring tank, first collect the full amount. , then one of the glass rods must be moved to collect the remaining amount, which is laborious and time consuming. In addition, the amount required is large, and collecting a small amount of liquid requires even more effort and time.
本発明ではこのようなそれぞれの場合２個の計量槽があ
るので、一方の計量槽の液の設定量を予めはんばまたは
こきざみのごく少量に設定してお＝３−
けばよい。In the present invention, there are two measuring tanks in each of these cases, so it is sufficient to set the amount of liquid in one of the measuring tanks to a very small amount, such as a small amount or a small amount.
例えば計量槽の容量が最大１００ｍ１までしか設定でき
ない場合１５０ｍ１のごときはんばの量を採取したい時
は、従来の装置ではまず設定量を１００ｍ１とし、ｌｏ
Ｏｍｌを採取した後、次に一方のロッドを移動して設定
量を５０ｍ１と変更してから、残りの５０ｍ１を採取し
、１５０ｍ１とせねばならなかったが、本発明では予め
計量槽（Ａ）の液の設定量を１００ｍ１とし、計量槽（
Ｂ）の液の設定量を５０ｍ１としておけば１回の操作の
僅かな時間で１５０ｍ１の所要量が採取でき、従来の装
置のようなロッドの移動というような面倒な手数を要し
ない。For example, if the capacity of the measuring tank can only be set to a maximum of 100 m1 and you want to collect a quantity of 150 m1, the conventional device first sets the set volume to 100 m1, and then
After collecting Oml, one rod had to be moved to change the set amount to 50ml, and then the remaining 50ml had to be collected to make 150ml, but in the present invention, the amount in the measuring tank (A) was adjusted in advance. The set amount of liquid is 100ml, and the measuring tank (
If the set amount of liquid B) is set to 50 ml, the required amount of 150 ml can be collected in a short time in one operation, and there is no need for troublesome steps such as moving the rod as in conventional devices.
また例えば４２５ｍ１のようなこきざみの量を採取した
い時は従来の装置ではさらに多くの時間と手数を要する
が、本発明では計量槽（Ａ）では設定量を１００ｍ１と
し、計量槽（Ｂ）では設定量を５ｍｌとし、計量槽（Ａ
）ではＮを４．計量槽（Ｂ）ではＮを５と選んでおけば
、電子回路により計量槽（＾）では４回の液の流入・流
出が、計量槽（Ｂ）では５回の液の流入・流出が行われ
、迅速かつ正確に合計４２５ｍ１の液が容易に自動的に
容器に採取される。Furthermore, if you want to sample a small amount such as 425 m1, it takes more time and effort with conventional equipment, but in the present invention, the set amount is set to 100 m1 in the measuring tank (A), and the set amount in the measuring tank (B) is set to 100 m1. Set the volume to 5 ml, and add it to the measuring tank (A
) then set N to 4. If N is selected as 5 for the measuring tank (B), the electronic circuit will cause the liquid to flow in and out of the measuring tank (^) four times, and the liquid will flow in and out of the measuring tank (B) five times. A total of 425 ml of liquid is easily and automatically collected into a container quickly and accurately.
（ｃ）２液の混合、希釈を同時に行う場合従来の計量槽
１個の装置ではこのような場合は使用できなかった。(c) When mixing and diluting two liquids at the same time Conventional devices with one measuring tank cannot be used in such cases.
しかし本発明では計量槽が２個なので、この場合は貯槽
を２個使用し、それぞれに異った液、例えばＡ液Ｂ液を
入れておけばよい。However, in the present invention, there are two measuring tanks, so in this case, two storage tanks may be used and different liquids, for example, liquid A and liquid B, may be placed in each storage tank.
すなわち第２図に示すように、Ａ液を入れた貯槽（Ａ）
１３は電磁弁２を通じ計量槽（Ａ） Ｉと連結してあり
、またＢ液を入れた貯槽（Ｂ）１４は電磁弁７を通じ計
量槽（Ｂ）６と連結しておけば容易に２液の混合が同時
に行うことができ、所要の割合の混合液を自動的に正確
かつ迅速に得ることができる。In other words, as shown in Figure 2, a storage tank (A) containing liquid A
13 is connected to the measuring tank (A) I through the solenoid valve 2, and the storage tank (B) 14 containing liquid B can be easily connected to the measuring tank (B) 6 through the solenoid valve 7. can be mixed at the same time, and the desired ratio of mixed liquid can be automatically obtained accurately and quickly.
例えば計量槽（Ａ） （Ｂ）共役定量１００ｍ１とし、
Ａ液を２００ｍ１Ｂ液を３００ｍ１合計５００ｍ１ノ混
合液を得たい時は、計量槽（Ａ）ではＮを２計量槽（Ｂ
）ではＮを３と選んでおけば電子回路により計量槽（Ａ
）ではＡ液の２回の流入・流出が、計量槽（Ｂ）ではＢ
液の３回の流入・流出が行われ、迅速かつ正確にＡ液：
Ｂ液が２：３の混合液５００ｍ１が容易に容器に採取さ
れる。For example, if the measuring tank (A) (B) is conjugate quantitative 100 m1,
When you want to obtain a mixed solution of 200ml of liquid A, 300ml of liquid B, and 1 total of 500ml, add N in 2 measuring tanks (B) in the measuring tank (A).
), if N is selected as 3, the electronic circuit will control the measuring tank (A
), liquid A flows in and out twice, and liquid B flows in the measuring tank (B) twice.
Three times of inflow and outflow of liquid are carried out, quickly and accurately A liquid:
500 ml of a 2:3 mixed solution of B solution is easily collected into a container.
またもしＡ液が溶媒であり、Ｂ液が溶質またはある虫の
溶媒に溶かされた溶質とすれば、２液の混合により希釈
も行うことができる。Furthermore, if liquid A is a solvent and liquid B is a solute or a solute dissolved in a certain insect solvent, dilution can also be achieved by mixing the two liquids.
