Description
【０００１】[0001]
本考案は、ダイヤフラムポンプ等を駆動するポンプ駆動用アクチュエータに関 係する。 The present invention relates to a pump drive actuator that drives a diaphragm pump or the like.
【０００２】[0002]
従来、この種のポンプ駆動用アクチュエータは、図２及び図３に示すように、 ポンプ１のダイヤフラム１０の中央に駆動軸１１が取り付けられ、駆動軸１１は 揺動用Ｌ字型ヨーク５の中間に固定され、該Ｌ字型ヨーク５は上端を揺動中心ピ ン８に回転自在に取り付けられ、下端に直方体状の永久磁石が固定され、Ｌ字型 ヨーク５は矢印６で示す揺動運動ができ、この運動によりポンプを駆動する。そ の揺動運動の原理は、前記Ｌ字型ヨーク５に取り付けられた永久磁石２の下方に 接近してＥ字型ヨーク３が配置され、このＥ字型ヨーク３の中央磁脚の回りに巻 線されたコイル４に交番電流を通電することにより、前記Ｅ字型ヨーク３の磁脚 の上面の磁極面１２に、交互にＮ極、Ｓ極を発生させる。永久磁石２の磁極面１ ３の磁極とＥ字型ヨーク３の磁極面１２の交番磁極は互いに吸引、反発を交互に 行い、Ｌ字型ヨーク５を揺動させ、Ｌ字型ヨーク５はダイヤフラム１０の駆動軸 １１を前後に移動させ、ダイヤフラム１０に前後運動させて、ポンプ１を駆動し ている。 従来のポンプ駆動用アクチュエータでは、図３に示すように、Ｌ字型ヨーク５ が垂直方向から矢印９の方向に揺動した場合は、ポンプ１のダイヤフラム１０は 図示した変位７だけふくらみ吸引を行う。次に極性が変わり反発力により戻され るが、図２及び図３からわかるように従来の永久磁石２の磁極面１２とＥ字型ヨ ーク３の磁極面１３は各々平面に加工されているため、Ｅ字型ヨーク３の磁極面 １２と永久磁石２の磁極面１３との空隙部が図３の状態では等間隔にならず、磁 気的な効率が悪くなり、必要な消費電力が高いという欠点があった。 Conventionally, in this type of pump drive actuator, as shown in FIGS. 2 and 3, a drive shaft 11 is attached to the center of a diaphragm 10 of a pump 1, and the drive shaft 11 is provided in the middle of an L-shaped yoke 5 for swinging. The L-shaped yoke 5 is fixed, and the upper end of the L-shaped yoke 5 is rotatably attached to the swing center pin 8, and a rectangular parallelepiped permanent magnet is fixed to the lower end of the L-shaped yoke 5. Yes, this movement drives the pump. The principle of the oscillating motion is that an E-shaped yoke 3 is arranged below the permanent magnet 2 attached to the L-shaped yoke 5, and the E-shaped yoke 3 is arranged around the central magnetic leg. By supplying an alternating current to the wound coil 4, N poles and S poles are alternately generated on the magnetic pole surface 12 on the upper surface of the magnetic leg of the E-shaped yoke 3. The magnetic poles of the magnetic pole surface 13 of the permanent magnet 2 and the alternating magnetic poles of the magnetic pole surface 12 of the E-shaped yoke 3 alternately attract and repel each other to swing the L-shaped yoke 5, and the L-shaped yoke 5 is a diaphragm. The drive shaft 11 of 10 is moved back and forth, and the diaphragm 10 is moved back and forth to drive the pump 1. In the conventional pump driving actuator, as shown in FIG. 3, when the L-shaped yoke 5 swings from the vertical direction in the direction of the arrow 9, the diaphragm 10 of the pump 1 bulges and sucks by the displacement 7 shown in the drawing. . Next, the polarity changes and is returned by the repulsive force. As can be seen from FIGS. 2 and 3, the magnetic pole surface 12 of the conventional permanent magnet 2 and the magnetic pole surface 13 of the E-shaped yoke 3 are each processed into a flat surface. Therefore, the gaps between the magnetic pole surface 12 of the E-shaped yoke 3 and the magnetic pole surface 13 of the permanent magnet 2 are not evenly spaced in the state shown in FIG. 3, magnetic efficiency is deteriorated, and required power consumption is reduced. It had the drawback of being expensive.

【考案が解決しようとする課題】 本考案の課題は、これらの欠点を除去した、Ｅ字型ヨークの磁極面と永久磁石 の磁極面が、駆動時においても何れの場所でも一定の間隔で変化がない構造で、 効率の良いポンプ駆動用アクチュエータを提供することにある。The problem to be solved by the present invention is to eliminate the above drawbacks and to change the magnetic pole surface of the E-shaped yoke and the magnetic pole surface of the permanent magnet at a constant interval at any place during driving. The purpose is to provide an efficient pump drive actuator with a structure that does not have any structure.
【０００４】[0004]
本考案は、上述の課題を解決するため、ポンプ駆動用アクチュエータのＥ字型 コアの磁極面と、Ｌ字型ヨークの先端に付けられた永久磁石の磁極面が所定の間 隙をもって、揺動中心ピンを中心とする同心状の曲面から形成されていることを 特徴とするポンプ駆動用アクチュエータを供する。 In order to solve the above problems, the present invention oscillates with a predetermined gap between the magnetic pole surface of the E-shaped core of the pump driving actuator and the magnetic pole surface of the permanent magnet attached to the tip of the L-shaped yoke. Provided is a pump driving actuator, which is characterized by being formed from a concentric curved surface centered on a center pin.
【０００５】 即ち、本考案は、Ｅ字型ヨークとこのヨークの中央磁脚の回りに巻かれたコイ ルと、一端が揺動中心ピンに回転自在に固定されたＬ字型ヨークと、このヨーク の下面に固定された永久磁石を基本構成要素としてなるポンプ駆動用アクチュエ ータにおいて、永久磁石の磁極面と該永久磁石の磁極面に対向するＥ字型ヨーク の磁極面を、同一中心の円弧状の曲面からなる構造を特徴とするポンプ駆動用ア クチュエータである。That is, the present invention provides an E-shaped yoke, a coil wound around a central magnetic leg of the yoke, an L-shaped yoke whose one end is rotatably fixed to a swing center pin, and In a pump drive actuator having a permanent magnet fixed to the lower surface of the yoke as a basic constituent element, the magnetic pole surface of the permanent magnet and the magnetic pole surface of the E-shaped yoke facing the magnetic pole surface of the permanent magnet have the same center. This is a pump drive actuator characterized by a structure formed by an arcuate curved surface.
【０００６】[0006]
本考案では、ポンプ駆動用アクチュエータのピストン運動を発生させるＬ字型 ヨークの揺動運動の起動力を発生させる永久磁石の磁極面とＥ字型ヨークの磁極 面の間隙が、揺動中、常に一定になる構造になっているので、機械的に近づける 範囲で最も狭い間隙にでき、しかも、常にその間隙で動作するので、最も効率の よい状態で動作し、消費電力を節減できる。 According to the present invention, the gap between the magnetic pole surface of the permanent magnet and the magnetic pole surface of the E-shaped yoke, which generates the starting force of the swing motion of the L-shaped yoke that causes the piston motion of the pump driving actuator, is constantly maintained during the swing. Since the structure is constant, the narrowest gap can be created within the mechanically close range, and because the gap always operates, it operates in the most efficient state and saves power consumption.

以下、図面を用いて、本考案の実施例を説明する。図１は本考案の実施例のポ ンプ駆動用アクチュエータの構造を説明するための説明図である。 図１に示すように、本考案のポンプ駆動用アクチュエータは、ポンプ１の本体 の下方に固定されたＥ字型ヨーク３の左半分が断面で示されているように背中合 せの対で用いられるポンプの左側のポンプを用いて説明する。Ｅ字型ヨーク３は 中央の磁脚の回りにコイル４が巻かれており、交流電流が流される。Ｅ字型ヨー ク３の上面の磁極面１２は、上方のＬ字型ヨーク５の揺動の中心を中心とする円 弧状の曲面に加工されている。ポンプ１のダイヤフラム１０を駆動する駆動軸１ １はダイヤフラム１０の中心部とＬ字型ヨーク５の中間部を接続している。Ｌ字 型ヨーク５は上端を揺動中心ピン８に回転自在に接続し、下方には永久磁石２が 固定され、永久磁石２の下面の磁極面１３は揺動の中心を中心とした円弧状の曲 面に仕上げられている。永久磁石２の磁極面１３は、Ｅ字型ヨーク３の磁極面１ ２に接しない程度に出来るだけ近づけて配置され、揺動中はその各々の磁極面１ ２間の間隙は、何れの場所でも一定になる構造である。 従って、コイル４に交流電流を通電して、永久磁石２を揺動する場合永久磁石 ２の磁極面１３とＥ字型ヨーク３の磁極面１２の対向する間隙は、何れの場所で も、いつも一定で平均した間隙距離を最小にできる構造である。 以上の構造のポンプ駆動用アクチュエータを使用してポンプを駆動したところ 従来より約１０％の電力が節減できた。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view for explaining the structure of a pump drive actuator according to an embodiment of the present invention. As shown in FIG. 1, the pump driving actuator of the present invention is used in a back-to-back pair as shown by the left half of the E-shaped yoke 3 fixed below the body of the pump 1. The description will be given using the pump on the left side of the pump. The E-shaped yoke 3 has a coil 4 wound around the magnetic leg at the center, and an alternating current is passed through it. The magnetic pole surface 12 on the upper surface of the E-shaped yoke 3 is processed into an arc-shaped curved surface centered on the swing center of the upper L-shaped yoke 5. A drive shaft 11 that drives the diaphragm 10 of the pump 1 connects the central portion of the diaphragm 10 and the intermediate portion of the L-shaped yoke 5. The upper end of the L-shaped yoke 5 is rotatably connected to the swing center pin 8 and the permanent magnet 2 is fixed to the lower part thereof. The magnetic pole surface 13 on the lower surface of the permanent magnet 2 has an arc shape around the swing center. It is finished on the curved surface. The magnetic pole surface 13 of the permanent magnet 2 is disposed as close as possible to the magnetic pole surface 12 of the E-shaped yoke 3, and during the swinging, the gap between the magnetic pole surfaces 12 is any place. But the structure is constant. Therefore, when an alternating current is applied to the coil 4 to swing the permanent magnet 2, the gap between the magnetic pole surface 13 of the permanent magnet 2 and the magnetic pole surface 12 of the E-shaped yoke 3 facing each other is always constant. It is a structure that can minimize the constant and average gap distance. When the pump was driven using the pump driving actuator having the above structure, about 10% of electric power was saved compared with the conventional one.
