例えば光学的方法によって測定研究される。In many analyses, precisely defined amounts of reagents are added to liquid samples, and the effect of this reagent on these samples is measured and studied, for example by optical methods.
このプロセスを自動化するためには、正確に規定された
量の試薬を試料に加えることができる希゛釈装置が必要
である。To automate this process, a dilution device is required that can add precisely defined amounts of reagents to the sample.
この量の正確さは多量であれ少量であれ高くなければな

なければならないために、速やかに行わねばならない。The accuracy of this quantity must be high, whether large or small, and the addition of reagents must be done quickly, as often a large number of samples have to be measured.
更に試薬は円滑に添加することが重要である。Furthermore, it is important to add the reagents smoothly.
そうでないと十分な精度を得ることが困難であるからで
ある。This is because otherwise it is difficult to obtain sufficient accuracy.
通常、希釈を行うには試薬容器をピストンポンプに接続
し、このポンプが弁を介して正確に規定された量の試薬
をポンプシリンダに吸入し、そして試薬を試料容器にス
プレィする。Typically, dilution is accomplished by connecting the reagent container to a piston pump, which draws a precisely defined amount of reagent into the pump cylinder via a valve, and sprays the reagent into the sample container.

従って本発明の目的は上述の欠点を克服したピストンポ
ンプの駆動手段を提供するにある。SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide means for driving a piston pump which overcomes the above-mentioned disadvantages.
以下図面の実施例に従って詳細に説明する。A detailed description will be given below according to the embodiments shown in the drawings.
図において、では駆動シャフトで、駆動手段（図示路）
によって正逆両方向（時計方向または反時計方向）に選
択的に回転させられる。In the figure, the drive shaft is the drive means (the path shown).
can be selectively rotated in both forward and reverse directions (clockwise or counterclockwise).
このシャフトには連結ピン３によって駆動板２が固定さ
れている。A drive plate 2 is fixed to this shaft by a connecting pin 3.
駆動板２に近接して連結板７がシャフト１上に軸受され
ている。A coupling plate 7 is journaled on the shaft 1 adjacent to the drive plate 2 .
駆動板２と連結板７は引っばりばね（ｄｒａｗｓｐｒｉ
ｎｇ）１２によって互いに弾力的に連結されている。The driving plate 2 and the connecting plate 7 are provided with an extension spring (drawspring).
ng) are elastically connected to each other by 12.
すなわちばね１２はその一端が連結板７のばね取付部１
３に、また他端が駆動板２のばね取付は部１４に各々連
結されている。That is, the spring 12 has one end connected to the spring mounting portion 1 of the connecting plate 7.
3 and the other end of the drive plate 2 are connected to the spring mounting portion 14, respectively.
ばね１２の張力によって連結板７はシャフト１上で時計
方向に付勢されているので、連結板７のシャンク１５が
駆動板２の屈折部１６に対して押しつけられている。Since the connecting plate 7 is biased clockwise on the shaft 1 by the tension of the spring 12, the shank 15 of the connecting plate 7 is pressed against the bent portion 16 of the drive plate 2.
シャフト１には更に被駆動板９が軸受されている。A driven plate 9 is further supported on the shaft 1 .
被駆動板９はばね８によって反時計方向に付勢されてい
るので、被駆動板９の屈折部９’ａは連結板７のシャン
ク１５に押しつけられている。Since the driven plate 9 is biased counterclockwise by the spring 8, the bent portion 9'a of the driven plate 9 is pressed against the shank 15 of the connecting plate 7.
ばね８はその一端が被駆動板９のスプリングピン１０に
、他端が静止枠１１にそれぞれ連結されている。The spring 8 has one end connected to a spring pin 10 of the driven plate 9, and the other end connected to a stationary frame 11.
更にばね１７が駆動板２と枠１１の間に連結されている
。Furthermore, a spring 17 is connected between the drive plate 2 and the frame 11.
ばね１７の引張り力はばね８による力の方向と反対方向
に装置に作用する。The tensile force of spring 17 acts on the device in a direction opposite to the direction of the force exerted by spring 8.
すなわち、ばね１７は駆動板２を時計方向に付勢してい
る。That is, the spring 17 biases the drive plate 2 clockwise.
被駆動板９には突出したホーク状部１８がありこれがロ
ッド２１に附設されたピン２０上に軸受されたローラ１
９と係合している。The driven plate 9 has a protruding fork-shaped portion 18 which supports the roller 1 which is supported on a pin 20 attached to a rod 21.
It is engaged with 9.
ロッド２１は２つのガイド２２，２３によって軸方向に
可動に支持されている。The rod 21 is supported movably in the axial direction by two guides 22 and 23.
ロッド２１には例えばピストンポンプのピストンポンプ
（図示路）が連結できるようになった延長アーム２４が
設けられている。The rod 21 is provided with an extension arm 24 to which, for example, a piston pump (path shown) can be connected.
ロッド２１の変位は二つのねじ２５，２６によって制限
される。The displacement of the rod 21 is limited by two screws 25,26.
実際上はねじ２６は異ったレベルの多数のストップピン
からなり、ロッド２１に異ったストロークを与えること
ができるようになっている。In practice, the screw 26 consists of a number of stop pins at different levels, making it possible to impart different strokes to the rod 21.
上述した装置は次のように動作する。The device described above operates as follows.
今、ロッド２１が第１図に示す位置にあって、シャフト
１が反時計方向（矢印Ａの方向）に駆動されると仮定す
ると、このシャフトに固定された駆動板２も同じ方向に
回動しばね１７が伸張され、駆動板２の屈折部１６が連
結板７のシャンク１５を押すので、このシャンク１５従
って連結板７も反時計方向に回動させられる。Now, assuming that the rod 21 is in the position shown in Figure 1 and the shaft 1 is driven counterclockwise (in the direction of arrow A), the drive plate 2 fixed to this shaft will also rotate in the same direction. Since the tie spring 17 is expanded and the bent portion 16 of the driving plate 2 pushes the shank 15 of the connecting plate 7, this shank 15 and therefore also the connecting plate 7 is rotated counterclockwise.
シャンク１５が反時計方向に回動するとシャンク１５は
被駆動板９の屈折部９ａから離れようとするが、ばね８
がシャフト１の回転方向（反時計方向）に被駆動板９を
追従回動させる。When the shank 15 rotates counterclockwise, the shank 15 tries to move away from the bent portion 9a of the driven plate 9, but the spring 8
causes the driven plate 9 to follow and rotate in the rotational direction of the shaft 1 (counterclockwise).
これにより被駆動板９のホーク状部１８とロー、う１９
の係合を介してロッド２１は下方向に動かされ、アーム
２４がねじ２６に接する。As a result, the hawk-shaped portion 18 of the driven plate 9 and the row, ridge 19
The rod 21 is moved downward through the engagement of the arm 24 and the screw 26 .
この時点において、被駆動板９は停止するが、駆動板２
と連結板７はシャフト１の回転方向が逆にされるまでな
お反時計方向に動き、連結板７のシャンク１５が被駆動
板９の屈折部９ａから離れる。At this point, the driven plate 9 stops, but the driving plate 2
and the coupling plate 7 still moves counterclockwise until the direction of rotation of the shaft 1 is reversed, and the shank 15 of the coupling plate 7 separates from the bend 9a of the driven plate 9.
（第３図の状態）第３図の状態からシャフト１の回転方
向を逆に時計方向（矢印Ｂの方向）にすると、駆動板２
も時計方向に回動され、ばね１２による連結を介して連
結板Ｉも時計方向に回動される。(Situation shown in Figure 3) When the rotation direction of the shaft 1 is reversed from the state shown in Figure 3 to the clockwise direction (direction of arrow B), the drive plate 2
is also rotated clockwise, and the connecting plate I is also rotated clockwise via the connection by the spring 12.
このときシャフト１の駆動手段はばね１７の引張り力に
よって助けられる。The driving means of the shaft 1 is then assisted by the tension force of the spring 17.
この時計方向の回動により連結板７のシャンク１５が被
駆動板９の屈折部９ａに係合するに至り、さらにシャフ
ト１および駆動板２従って連結板７が時計方向に回動を
続けると、被駆動板９を時計方向に回動させホーク状部
１８とローラ１９との係合を介してロッド２１を上方向
に動かす。This clockwise rotation causes the shank 15 of the connecting plate 7 to engage with the bent portion 9a of the driven plate 9, and when the shaft 1, driving plate 2, and therefore the connecting plate 7 continue to rotate clockwise, The driven plate 9 is rotated clockwise and the rod 21 is moved upward through engagement between the hawk-shaped portion 18 and the roller 19.
この運動はロッド２１がねじ２５に当接するまで続く（
第１図）。This movement continues until the rod 21 abuts the screw 25 (
Figure 1).
ロッド２１の上端がねじ２５に当ると被駆動板９の時計
方向の回動は停止し、シャンク１５が屈折部９ａと係合
しているから連結板７の回動も停止する。When the upper end of the rod 21 hits the screw 25, the clockwise rotation of the driven plate 9 is stopped, and since the shank 15 is engaged with the bent portion 9a, the rotation of the connecting plate 7 is also stopped.
しかし駆動板２はシャフト１に固定されているために、
なお時計方向に回転し続ける。However, since the drive plate 2 is fixed to the shaft 1,
It will continue to rotate clockwise.
従って駆動板２の屈折部１６が連結板７のシャンク１５
から時計方向に離れ、ばね１２が伸張される（第４図）
。Therefore, the bent portion 16 of the driving plate 2 is connected to the shank 15 of the connecting plate 7.
away from the clockwise direction, the spring 12 is stretched (Fig. 4)
.
駆動板２の時計方向への回動とばね１２の伸張はシャフ
ト１の回転方向を逆に反時計方向にするまで続く。The clockwise rotation of the drive plate 2 and the extension of the spring 12 continue until the direction of rotation of the shaft 1 is reversed and counterclockwise.
第４図の状態からシャフト１の回転方向を反時針方向に
すると、このシャフトの回転により駆動板２の屈折部１
６がやがて連結板７のシャンク１５と係合しく第１図の
状態）、上述のプロセスが繰返えされる。When the rotation direction of the shaft 1 is set to the counterclockwise direction from the state shown in FIG.
6 eventually engages the shank 15 of the coupling plate 7 (as shown in FIG. 1), and the process described above is repeated.
本発明の構成によれば、駆動板２と被駆動板９は相対的
に回動可能であるので、ロッド２１を種種異なる所望の
ストロークに簡単に調節することができ、従って延長ア
ーム２４を介してロッドに連結されたピストンポンプの
ピストンのストロークを調節することができる。According to the configuration of the invention, the driving plate 2 and the driven plate 9 are relatively rotatable, so that the rod 21 can be easily adjusted to different desired strokes, so that the rod 21 can be easily adjusted to different desired strokes. The stroke of the piston of the piston pump connected to the rod can be adjusted by using the piston rod.
この調節はねじ２６の代りに異った長さの多数のねじを
用い、これを枠１１にブツシュボタンによって導入する
ことによって行うことができる。This adjustment can be effected by replacing the screw 26 with a number of screws of different lengths, which are introduced into the frame 11 by means of pushbuttons.
ねじ２５を動かすことによってピストンポンプの容量の
最終的な調節を行うことができる。A final adjustment of the piston pump capacity can be made by moving the screw 25.
この装置の他の利点はシャフト１を駆動するモータがロ
ッド２１の動きの各半サイクル中はぼ同じ負荷を負担す
るようになっていることである。Another advantage of this device is that the motor driving the shaft 1 carries approximately the same load during each half cycle of the movement of the rod 21.
なぜならばね１７の力がばね８の力とは反対方向を有し
ているからである。This is because the force of spring 17 has an opposite direction to the force of spring 8.
更に他の利点はロッド２１が停止したあともシャフト１
の回転が持続し、このシャフトの回転動作をポンプの弁
のスイッチング操作を行うのに利用できることである。Another advantage is that even after the rod 21 has stopped, the shaft 1
The rotation of the shaft continues, and this rotational movement of the shaft can be used to perform switching operations on the valves of the pump.
例えばスプレィサイクルのあとシャフトがその回転方向
の逆転位置で停止する前に弁を吸入位置に切換えるのに
利用できる。For example, it can be used to switch the valve to the suction position after a spray cycle and before the shaft stops in its rotational reversal position.
このことは液体貯蔵容器がポンプに直結されポンプが容
器と供に枠から取りはずされる構成のこのような装置に
おいて非常に便利なことである。This is very convenient in such devices where the liquid storage container is connected directly to the pump and the pump is removed together with the container from the frame.
弁が切換えられないと、ポンプと容器を取り下したとき
、例えば温度の変化ないしはピストンのちよつとした動
ぎによって液体がポンプからスプレィされる危険性があ
る。If the valve is not switched, there is a risk that liquid will be sprayed out of the pump when the pump and container are removed, for example due to temperature changes or jerky movements of the piston.
