Description

本発明はプローブ振動制御装置に関し、更に詳しくは液体を吸引・注入するに際し、液体が周囲に飛散しないようにしたプローブ振動制御装置に関する。   The present invention relates to a probe vibration control device, and more particularly to a probe vibration control device that prevents liquid from splashing around when sucking and injecting liquid.

液体の自動分析装置においては、液体を容器に注入したり、容器からの液体を吸引したりする液体の吸引・注入装置が用いられる。図５は従来装置の構成例を示す図である。図において、１は液体を注入或いは吸引するプローブであり、４は液体の注入か又は液体の吸引を行なう容器である。プローブ１はプローブ支持部材２の一端に取り付けられている。   In an automatic liquid analyzer, a liquid suction / injection device that injects liquid into a container or sucks liquid from the container is used. FIG. 5 is a diagram showing a configuration example of a conventional apparatus. In the figure, 1 is a probe for injecting or sucking liquid, and 4 is a container for injecting or sucking liquid. The probe 1 is attached to one end of a probe support member 2.

該プローブ支持部材２の他端には、回転軸／上下動軸３が取り付けられている。この回転軸／上下動軸３が回転すると、プローブ支持部材２は回転する。支持部材２が回転すると、これに取り付けられているプローブ１も回転する。或いはこの回転軸は更に上下動も可能な軸となっている。   At the other end of the probe support member 2, a rotating shaft / vertical moving shaft 3 is attached. When the rotating shaft / vertical moving shaft 3 rotates, the probe support member 2 rotates. When the support member 2 rotates, the probe 1 attached to the support member 2 also rotates. Alternatively, this rotating shaft is a shaft that can further move up and down.

従来のこの種の装置としては、反応セル内にノズルを挿入する場合において、液体の分注量に応じてノズルの先端とセルの底部の距離が最適な値になるように制御する装置が知られている（例えば特許文献１参照）。或いは、液体を注入する際に注入時の過渡的な状態で、液滴が飛散して飛ばないように、液体が流れる流路の位置に流路の小さい抵抗部を設けた装置が知られている（例えば特許文献２参照）。   As a conventional device of this type, when a nozzle is inserted into a reaction cell, a device that controls the distance between the tip of the nozzle and the bottom of the cell to an optimum value according to the amount of liquid dispensed is known. (See, for example, Patent Document 1). Alternatively, there is known a device in which a small resistance portion of a flow path is provided at a position of a flow path through which liquid flows so that liquid droplets do not scatter and fly in a transitional state at the time of liquid injection. (For example, refer to Patent Document 2).

３）プローブ１の急加速開始時に、プローブ１の先端外壁部に付着している液体がプローブの振動により飛び散る。
４）プローブ１の急停止時にプローブ１の先端外壁部に付着している液体がプローブの振動により飛び散る。
５）プローブ１が液体を吸引する際に、液面付近で下降動作を終了させる場合にプローブ先端の振動により、液面が引っ掻かれ吸引不良を起こす。
６）プローブ支持部材２の剛性確保により振動を抑制する場合には、プローブ支持部材２が大型化してしまい、プローブの高速動作が困難になる。 However, the prior art has the following problems.
1) At the start of rapid acceleration of the probe 1, the liquid sucked into the probe tip part is ejected by the vibration of the probe 1.
2) When the probe 1 is suddenly stopped, the liquid sucked into the probe tip portion is ejected by the vibration of the probe 1.
3) When the probe 1 starts sudden acceleration, the liquid adhering to the outer wall of the tip of the probe 1 is scattered by the vibration of the probe.
4) When the probe 1 suddenly stops, the liquid adhering to the outer wall of the tip of the probe 1 is scattered by the vibration of the probe.
5) When the probe 1 sucks the liquid, when the descent operation is terminated near the liquid surface, the liquid surface is scratched due to the vibration of the probe tip, causing a suction failure.
6) In the case where vibration is suppressed by ensuring the rigidity of the probe support member 2, the probe support member 2 becomes large and high-speed operation of the probe becomes difficult.

以下、本発明の実施の形態について、詳細に説明する。図１は本発明の構成例を示す図である。図５と同一のものは、同一の符号を付して示す。（ａ）は上面図、（ｂ）は側面図である。図において、１は液体を注入或いは吸引するプローブであり、４は液体の注入か又は液体の吸引を行なう容器である。プローブ１はプローブ支持部材２の一端に取り付けられている。   Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a diagram showing a configuration example of the present invention. The same components as those in FIG. 5 are denoted by the same reference numerals. (A) is a top view, (b) is a side view. In the figure, 1 is a probe for injecting or sucking liquid, and 4 is a container for injecting or sucking liquid. The probe 1 is attached to one end of a probe support member 2.

プローブ支持部材２の他端には、回転軸／上下動軸３が取り付けられている。この回転軸／上下動軸３が回転すると、プローブ支持部材２は回転する。支持部材２が回転すると、これに取り付けられているプローブ１も回転する。或いはこの回転軸は更に上下動も可能な軸となっている。   At the other end of the probe support member 2, a rotating shaft / vertical moving shaft 3 is attached. When the rotating shaft / vertical moving shaft 3 rotates, the probe support member 2 rotates. When the support member 2 rotates, the probe 1 attached to the support member 2 also rotates. Alternatively, this rotating shaft is a shaft that can further move up and down.

本発明では、プローブ支持部材２を第１のプローブ支持部材とする。プローブ１は第１のプローブ支持部材２から突き出ており、この突き出た部分に第２のプローブ支持部材１０が取り付けられている。第１のプローブ支持部材２の材料としては例えばアルミニウムが用いられ、第２のプローブ支持部材１０としては例えばステンレスが用いられる。   In the present invention, the probe support member 2 is a first probe support member. The probe 1 protrudes from the first probe support member 2, and the second probe support member 10 is attached to the protruding portion. For example, aluminum is used as the material of the first probe support member 2, and stainless steel is used as the second probe support member 10, for example.

第１のプローブ支持部材２と第２のプローブ支持部材１０は、側面から見てほぼ平行となるように設置されている。１１は第１のプローブ支持部材２と第２のプローブ支持部材１０の間に設けられた弾性体である。該弾性体としては、弾性のあるものであれば、図に示すようなバネでも、ゴム状のものであってもよい。   The first probe support member 2 and the second probe support member 10 are installed so as to be substantially parallel when viewed from the side. Reference numeral 11 denotes an elastic body provided between the first probe support member 2 and the second probe support member 10. The elastic body may be a spring as shown in the figure or a rubber-like one as long as it has elasticity.

１３は第１のプローブ支持部材２の一端に取り付けられた部材、１２は第２のプローブ支持部材１０と部材１３との間に取り付けられたプローブ駆動軸である。第１のプローブ支持部材２とプローブ駆動軸１２とのなす角θは、第２のプローブ支持部材１０の必要駆動量に応じて調整される。このように構成された装置の動作を説明すれば、以下の通りである。
（上下動作時）
１）プローブ１の上下動に伴い、急加速・停止を行なう。 Reference numeral 13 denotes a member attached to one end of the first probe support member 2, and reference numeral 12 denotes a probe drive shaft attached between the second probe support member 10 and the member 13. The angle θ formed by the first probe support member 2 and the probe drive shaft 12 is adjusted according to the required drive amount of the second probe support member 10. The operation of the apparatus configured as described above will be described as follows.
(Up and down operation)
1) As the probe 1 moves up and down, it suddenly accelerates and stops.

２）プローブ１や他の部品の質量により、第１のプローブ支持部材２に慣性力が働き、第１のプローブ支持部材２がしなる。
３）第１のプローブ支持部材２が下方向にしなる際には、プローブ駆動軸１２に引張荷重が生じる。上方向にしなる際には、圧縮荷重が生じる。この結果、第１のプローブ支持部材２が下方向にしなる場合には、プローブ駆動軸１２に上方向にしなるような力が働き、第１のプローブ支持部材２が下方向にしなる場合には、プローブ駆動軸１２に下方向にしなるような力が働き、プローブ１が回転軸／上下動軸３と平行になるように制御されることになる。 2) The inertial force acts on the first probe support member 2 due to the mass of the probe 1 and other components, and the first probe support member 2 is bent.
3) When the first probe support member 2 is in the downward direction, a tensile load is generated on the probe drive shaft 12. When going upward, a compressive load is generated. As a result, when the first probe support member 2 is in the downward direction, an upward force acts on the probe drive shaft 12, and when the first probe support member 2 is in the downward direction, A downward force acts on the probe drive shaft 12, and the probe 1 is controlled to be parallel to the rotation axis / vertical movement shaft 3.

４）一方、第２のプローブ支持部材１０は、弾性体１１に固定されているため、第１のプローブ支持部材２がしなっても、プローブ１と回転軸／上下動軸３との平行を保つように駆動する。具体的には、第１のプローブ支持部材２がしなっても、弾性体１１と第２のプローブ支持部材１０及びプローブ駆動軸１２とが相互作用しあい、そのしなりと反対側に振るような動作をして、第１のプローブ支持部材２のしなりがプローブ１に影響を与えないようにする。   4) On the other hand, since the second probe support member 10 is fixed to the elastic body 11, even if the first probe support member 2 does not, the probe 1 and the rotation axis / vertical movement axis 3 are parallel to each other. Drive to keep. Specifically, even if the first probe support member 2 does not, the elastic body 11, the second probe support member 10, and the probe drive shaft 12 interact with each other and swing to the opposite side. In operation, the bending of the first probe support member 2 does not affect the probe 1.

５）この結果、第１のプローブ支持部材２のしなりにともなうプローブ先端の位置変動ならびに振動を抑制することができる。
（回転動作時並びに平行移動時）
１）プローブ１の回転駆動又は平行移動に伴い、急加速・急停止を行なう。 5) As a result, it is possible to suppress positional variation and vibration of the probe tip accompanying the bending of the first probe support member 2.
(When rotating and moving in parallel)
1) As the probe 1 is rotationally driven or moved in parallel, sudden acceleration and sudden stop are performed.

２）プローブ１や他の部品の質量により、第１のプローブ支持部材２に慣性力が働き、第１のプローブ支持部材２は捻られる。
３）プローブ駆動軸１２に引張荷重又は圧縮荷重が生じ、第２のプローブ支持部材１０には第１の支持部材２とは逆方向に捻れるような荷重が発生する。 2) The inertial force acts on the first probe support member 2 due to the mass of the probe 1 and other components, and the first probe support member 2 is twisted.
3) A tensile load or a compressive load is generated on the probe drive shaft 12, and a load that twists in the opposite direction to the first support member 2 is generated on the second probe support member 10.

４）第２のプローブ支持部材１０に取り付けられたプローブ駆動軸１２に捻れを元に戻す力が働く。また、第１のプローブ支持部材２は、弾性体１１に固定されているため、第２の支持部材１０が第１のプローブ支持部材２の捻れとは逆方向に回転する。   4) A force to restore twisting acts on the probe drive shaft 12 attached to the second probe support member 10. Further, since the first probe support member 2 is fixed to the elastic body 11, the second support member 10 rotates in the direction opposite to the twist of the first probe support member 2.

５）この結果、第１のプローブ支持部材２の捻れが打ち消されて、プローブ１の先端の位置変動並びに振動を抑制することができる。
なお、プローブ駆動軸１２が第１のプローブ支持部材２に対して角度θだけ傾けて取り付けられているのは、第１のプローブ支持部材２が捻られた時に、その捻りを元に戻すような力を発生させるためである。第１のプローブ支持部材２に対してプローブ駆動軸１２が角度θだけ傾けて取り付けられている結果、第１のプローブ支持部材２に加えられる捻りのｓｉｎ成分又はｃｏｓ成分が捻りを元に戻すような力を与えることになる。 5) As a result, the twist of the first probe support member 2 is canceled out, and the position variation and vibration of the tip of the probe 1 can be suppressed.
The probe drive shaft 12 is attached to the first probe support member 2 at an angle θ so that when the first probe support member 2 is twisted, the twist is restored. This is to generate force. As a result of the probe drive shaft 12 being attached to the first probe support member 2 at an angle θ, the sin component or cos component of the twist applied to the first probe support member 2 restores the twist. Will give you the power.

このように、本発明によれば、前記プローブ１の他端部の一部が前記第１のプローブ支持部材２から突き出るようにして第２のプローブ支持部材１０に固定されると共に、該第２のプローブ支持部材１０と前記第１のプローブ支持部材２との間に弾性体１１を挿入し、かつ前記第２のプローブ支持部材１０から前記回転軸／上下動軸３との間に動作安定化のためのプローブ駆動軸１２が取り付けられて構成されるので、プローブ１の急加速、プローブの急停止等の場合に、プローブ１から液体が飛び散ることがないようにすることができる。   Thus, according to the present invention, a part of the other end of the probe 1 is fixed to the second probe support member 10 so as to protrude from the first probe support member 2, and the second An elastic body 11 is inserted between the probe support member 10 and the first probe support member 2, and the operation is stabilized between the second probe support member 10 and the rotary shaft / vertical movement shaft 3. Since the probe drive shaft 12 is attached and configured, the liquid can be prevented from splashing from the probe 1 in the case of rapid acceleration of the probe 1 or rapid stop of the probe.

図２は本発明装置の動作の一例を示す図である。図１と同一のものは、同一の符号を付して示す。回転軸／上下動軸３が下降動作を行ない急停止した場合は、プローブ１を支持する第１のプローブ支持部材２が慣性力で灰色に塗りつぶされた第１のプローブ支持部材２の状態になる。振動抑制機構が無い場合には、網掛けのプローブ１のような状態になる。   FIG. 2 shows an example of the operation of the apparatus of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. When the rotary shaft / vertical moving shaft 3 performs a lowering operation and suddenly stops, the first probe support member 2 that supports the probe 1 is in a state of the first probe support member 2 that is grayed out by inertia force. . When there is no vibration suppression mechanism, a state like the shaded probe 1 is obtained.

即ち、プローブ１の先端が振れてしまい、液体の飛び散りが発生しやすくなる。本発明によれば、灰色で塗りつぶされた状態になり、プローブ１は急停止されない時に下に向いていた状態が維持される。従って、液体が飛び散りやすくなることはない。   That is, the tip of the probe 1 is shaken and the liquid is likely to be scattered. According to the present invention, the state in which the probe 1 is painted in gray and the probe 1 faces downward when not suddenly stopped is maintained. Therefore, the liquid does not easily scatter.

図３は本発明装置の機械的構成例を示す図である。（ａ）が上面図、（ｂ）が側面図、（ｃ）がＣ−Ｃ断面図である。図１と同一のものは、同一の符号を付して示す。図の実施例では、Ｌ字型のプローブが取り付けられており、第２のプローブ支持部材１０が設けられている。（ｃ）に示すＣ−Ｃ断面図において１１が弾性体である。該弾性体１１としては、具体的にはゴムが用いられる。ゴムは回転軸／上下動軸３が急停止した時の振動を吸収する働きをする。ゴムは第１のプローブ支持部材２と第２の支持部材１０間に挟まれているだけである。   FIG. 3 is a diagram showing a mechanical configuration example of the apparatus of the present invention. (A) is a top view, (b) is a side view, and (c) is a CC cross-sectional view. The same components as those in FIG. 1 are denoted by the same reference numerals. In the illustrated embodiment, an L-shaped probe is attached and a second probe support member 10 is provided. In the CC cross-sectional view shown in FIG. Specifically, rubber is used as the elastic body 11. The rubber functions to absorb vibration when the rotary shaft / vertical shaft 3 stops suddenly. The rubber is only sandwiched between the first probe support member 2 and the second support member 10.

図４は本発明の他の構成例の要部を示す図である。この実施例では、プローブ駆動軸が１２Ａ，１２Ｂと２個設けられている。このようにプローブ駆動軸を２個設けると、第２のプローブ支持部材１０の追従性を向上させることができる。   FIG. 4 is a diagram showing a main part of another configuration example of the present invention. In this embodiment, two probe drive shafts 12A and 12B are provided. If two probe drive shafts are provided in this way, the followability of the second probe support member 10 can be improved.

以上、詳細に説明したように、本発明によれば以下のような効果が得られる。
１）プローブの回転駆動や平行駆動に伴う急加速並びに急停止する時に発生するプローブ先端での位置変動や振動を抑制することができるため、プローブ先端部内に吸引されている液体がプローブの振動により飛び出すことがなくなる。 As described above in detail, according to the present invention, the following effects can be obtained.
1) Since the position variation and vibration at the probe tip that occur when sudden acceleration and sudden stop due to the rotational drive and parallel drive of the probe can be suppressed, the liquid sucked into the probe tip is caused by the vibration of the probe. No more jumping out.

２）プローブの回転駆動や平行駆動に伴う急加速並びに急停止時に発生するプローブ先端での位置変動や振動を抑制することができるため、プローブ先端外壁に付着している液体がプローブの振動により飛び散ることがなくなる。   2) Position fluctuations and vibrations at the probe tip that occur during sudden acceleration and sudden stop associated with probe rotation and parallel drive can be suppressed, so that the liquid adhering to the probe tip outer wall scatters due to probe vibration. Nothing will happen.

３）プローブが液体を吸引する際に液面付近で下降動作を終了させる場合にはプローブ先端の振動が上下方向に抑制され、液面が引っ掻かれることがなくなり、吸引不良が発生することが無くなる。   3) When the descent operation is finished near the liquid level when the probe sucks the liquid, the vibration of the probe tip is suppressed in the vertical direction, the liquid level is not scratched, and a suction failure may occur. Disappear.

４）プローブ支持部材を高剛性化する必要がなく、第１のプローブ支持部材は小型軽量でよいため、プローブの高速駆動に対して非常に有利である。
このように、本発明によれば、プローブから液体が飛び散ることがないプローブ振動制御装置を提供することができる。 4) There is no need to increase the rigidity of the probe support member, and the first probe support member may be small and light, which is very advantageous for high-speed driving of the probe.
Thus, according to the present invention, it is possible to provide a probe vibration control device in which liquid does not scatter from the probe.
