【発明の詳細な説明】 ［技術分野］ 本発明はダイヤフラムポンプ等に用いる電磁式ポンプ駆
動装置に関するものである。TECHNICAL FIELD The present invention relates to an electromagnetic pump drive device used in a diaphragm pump or the like.

している。[Background Art] As a conventional electromagnetic pump drive device of this type,
There was a structure as shown in the figure. That is, in this conventional example, two E-shaped cores 1 are vertically arranged so as to face each other with an air gap 2 therebetween, and the mover 3 of the mover 3 is positioned horizontally in the center of the air gap 2 in the air gap 2. Both ends are elastically supported as much as possible by a diaphragm (not shown).
該ダイヤフラムは、空気を圧縮する役目と可動子３をエ
アギャップ２内に弾性支持する役目を持つものである。The diaphragm has a function of compressing air and a function of elastically supporting the mover 3 in the air gap 2.

た。Further, the permanent magnets 4a and 4b are fixed to the mover 3 so that the magnetic poles are opposite to each other while being separated from each other for a certain period. The operation of this conventional example is as shown in FIG.
When the magnetic poles of the polarities shown in a and 5b are excited so as to be generated on the opposing magnetic pole surfaces of the air gap 2, the permanent magnets 4a and 4b of the mover 3 generate an attracting force in the left direction in the figure, so that the mover 3 moves. When driven in the left direction and when an exciting current in the opposite direction is applied to the exciting coils 5a, 5b as shown in FIG. 14 (b), magnetic poles as shown in the figure are generated and permanent magnets 4a, 4 of the mover 3 are generated.
A rightward suction force is generated in b, and the mover 3 is driven to the right. By the way, in the case of the conventional example, since two E-shaped cores 1 are vertically arranged to face each other and an air gap 2 is formed in the middle thereof, the air gap length of the air gap 2 depends on the punching dimension of the E-shaped core 1. Since the air gap 2 needs to be set through some other component without being uniquely determined, the air gap length varies greatly during assembly, and therefore the suction force of the mover 3 varies, resulting in a discharge of the air pump. It had a drawback that the amount of air also varied.
また諸従来例の場合、可動子３の両端にはダイアフラム

は第１５図に示す如く、Ｅ型コア１の外側となり、可動
子３の支持点間の距離はＥ型コア１の外形寸法l1よりも
長い距離Ｗとなる。In addition, in the case of the conventional examples, diaphragms (not shown) are attached to both ends of the mover 3, but the supporting position of the diaphragm is outside the E-shaped core 1 as shown in FIG. The distance W between the supporting points is longer than the outer dimension l 1 of the E-shaped core 1.
一方永久磁石４ａ，４ｂと、各磁極間には第１４図
（ｂ）の矢印で示すベクトル的吸引力が働いており、可
動子３がエアギャップ２の上下方向に対して中心線上に
ある理想状態では、吸引力のｙ方向成分は上下で釣り合
っているため、互いに打ち消し合って零となっている。On the other hand, the vectorial attractive force indicated by the arrow in FIG. 14 (b) acts between the permanent magnets 4a and 4b and each magnetic pole, and the mover 3 is ideally located on the center line in the vertical direction of the air gap 2. In the state, the y-direction components of the attraction force are vertically balanced and thus cancel each other out to zero.
しかし通常では可動子３は中心線より僅かなりともずれ
て取り付けられており、この状態ではずれた距離の二乗
に反比例して、近寄った側のｙ方向吸引力は増加し、遠
のいた側のそれは減少することになり、上下で吸引力の
ｙ方向成分にアンバランスが生じる。However, normally, the mover 3 is attached so as to be slightly displaced from the center line. In this state, the y-direction attraction force on the approaching side increases in inverse proportion to the square of the displaced distance, and that on the far side is As a result, the y-direction component of the suction force is unbalanced in the vertical direction.
このアンバランスは両端のダイアフラムの逆向きの反発
弾性力でもって釣り合わされて、結果として可動子３は
中心線上よりある距離ずれた位置で、永久磁石４ａ，４
ｂの吸引力とダイアフラムの反発力との間で釣り合いが
生じて安定している。This imbalance is balanced by the opposite repulsive elastic forces of the diaphragms at both ends, and as a result, the mover 3 is displaced by a certain distance from the center line, and the permanent magnets 4a, 4a.
There is a balance between the suction force of b and the repulsive force of the diaphragm, which is stable.

いう問題があった。In this balanced state, the mover 3 is bent inside the mover 3 between the attraction force generation points of the permanent magnets 4a and 4b and the diaphragm support point in the direction shown by the broken line in FIG. Although the moment force is working, since the distance between the attraction force generation point and the support point is long, in other words, the distance W between the diaphragm support points is long, it is necessary to increase the frame strength of the mover 3, There has been a problem that the weight of the mover 3 is increased due to measures such as thickening the frame of the mover 3.
第１６図は筒状のコア１を用いた特開昭５４−８４６０
３号公報に見られる従来例であるが、第１３図従来例と
同様な問題を持つものであった。FIG. 16 is a diagram of Japanese Patent Application Laid-Open No. 54-8460 in which a tubular core 1 is used.
The conventional example seen in Japanese Patent No. 3 has the same problem as the conventional example shown in FIG.

いからである。Further, in the conventional example, the permanent magnets 4a, 4a on the mover 3 are
b is the direction of magnetization and the lateral length (the surface composed of the thickness and the lateral length is N as shown by the permanent magnets 4a and 4b in FIG. 13).
S-side. ) And the depth, the shape of the permanent magnets 4a and db is such that the depth dimension is longer than the lateral dimension. That is, in order to increase the thrust of the mover 3 and increase the amount of discharged air, it is generally sufficient to increase the magnet volume, but the lateral length of the permanent magnets 4a and 4b is the E-shaped core 1.
This is because the depth dimension of the permanent magnets 4a and 4b must be lengthened because it is determined by the distance l 2 between the central magnetic pole and the outer magnetic pole.

いう欠点を有していた。Then, the laminated thickness of the E-type core 1 must be set by a length equal to the depth dimension of the permanent magnets 4a, 4b. The laminated thickness of the E-shaped core 1 is provided for the purpose of forming magnetic poles corresponding to the depths of the permanent magnets 4a and 4b, not for preventing saturation of magnetic flux by the iron core. Since a silicon steel plate as a magnetic material having a high specific gravity must be stacked thickly, there is a drawback that the weight of the core 1 becomes heavy.

となるように可動子３に固定されている。Example 1 This example 1 corresponds to the first aspect of the present invention. As shown in FIG. 1, a date-shaped laminated core 1 is used, and an air gap 2 is formed at the center of the middle leg 1a of the core 1. Are provided, and exciting coils 5a and 5b are inserted on the upper and lower sides of the air gap 2, respectively. Further, a mover 3 is arranged in the air gap 2 so as to be movable in a direction orthogonal to the side surface of the core 1. In the mover 3, two permanent magnets 4a and 4b are fixed and separated from each other for a certain period. The permanent magnets 4a and 4b are fixed to the mover 3 such that the magnetic poles correspond to the opposing magnetic pole surfaces of the air gap 2 and the polarities of the magnetic poles are opposite to each other.

せた紙面と垂直方向に挿入した構成である。Here, the present embodiment will be described in comparison with the above-mentioned conventional example. To describe, the two cores having only the middle legs of the E-shaped core of the conventional example are brought into contact with each other to form the air gap 2 only in the central magnetic pole.
The movable element 3 is inserted into the air gap 2 in a direction perpendicular to the paper surface rotated by 90 ° from the conventional example.

る。Further, as shown in FIG. 1, the width of the middle leg 1a of the core 1 as the central magnetic pole is formed by punching out a magnetic material so that the width is equal to the depth of the permanent magnets 4a, 4b, and the laminated thickness of the core 1 is the second. The thickness A is shown in the figure, but the thickness A is set to a thickness at which the magnetic flux generated by the exciting coils 5a and 5b is not saturated.

らつきがないという利点を有するものである。Next, the distance W between the permanent magnets 4a and 4b shown in FIG. 2 (by the way, this surface becomes the NS surface) is set to the center even if the permanent magnets 4a and 4b are too far away or too close to the thickness A. Since the attraction force to the magnetic pole is small, it is set to A≈W. (The distance between the permanent magnets 4a and 4b in the conventional example may be the same A dimension as in the present embodiment.) Thus, in FIG. 1, a support means (not shown) is provided so that both ends of the mover 3 can vibrate. 3rd at the center position of the amplitude
When an exciting current is passed through the exciting coils 5a and 5b so that the opposite magnetic pole surfaces of the air gap 2 are excited to the polarity shown in FIG.
In the figure, an attractive force to the left acts on the permanent magnet 4b, and the mover 3 is driven in the arrow X direction. When a reverse exciting current is applied to the exciting coils 5a and 5b, the polarities of the magnetic pole surfaces of the air gap 2 are reversed, so that a rightward attracting force acts on the permanent magnet 4a, and the mover 3 is driven in the arrow Y direction. . Therefore, the mover 3 vibrates left and right by alternately changing the direction of the exciting current. Here, since the air gap length of the air gap 2 is uniquely determined by the dimension of the letter-shaped magnetic material forming the core 1, there is an advantage that the air cap length does not vary.
更に本実施例におけるダイアフラム支持間距離はＡ＋
（永久磁石の横長）×２であるに対して、従来例ではＷ
（≒Ａ）＋（永久磁石の横長）×２＋（外側磁極幅）×

の増大が図れる。Furthermore, the distance between diaphragm supports in this embodiment is A +
(Horizontal length of permanent magnet) × 2, whereas in the conventional example W
(≈A) + (horizontal length of permanent magnet) × 2 + (outer magnetic pole width) ×
Therefore, the bending moment acting on the mover 3 can be reduced by shortening the width of the outer magnetic pole by twice the width of the outer magnetic pole. As a result, a lightweight material can be used for the frame of the mover 3, the device can be downsized, and the driving force of the pump can be increased.

It is formed by the width of the middle foot 1a, which can be formed by punching steel plates, while the stacking direction is the exciting coils 5a, 5b.
The core 1 can be made smaller and lighter because the thickness of the core 1 does not saturate. FIGS. 4 (a) to 4 (c) show a specific example in which the present embodiment is incorporated into a diaphragm pump, in which the core 1 is housed in the central portion of the pump housing 6 and the openings on both side surfaces of the pump housing 6 are provided.

a and 7b are fixed, and so-called diaphragm rubbers 8a and 8b, which are elastic films, are stretched at the boundaries between the inward opening surfaces of the shell chamber housings 7a and 7b and the outward opening surface of the pump housing 6, respectively. The two housings 6 and 7a and 7b are separated from each other. The space formed by the diaphragm rubbers 8a and 8b and the shell chamber housings 7a and 7b constitutes the compression chambers 9a and 9b. The diaphragm rubbers 8a and 8b are sandwiched at their peripheral edges by the peripheral edges of the two housings 6 and 7a and 7b, and the center plate 10 is provided at the center.

命が長くなる。Next, the operation of a specific example of the diaphragm pump will be described. As described above, when the exciting current is alternately applied to the exciting coils 5a and 5b while reversing the polarities thereof to oscillate the mover 3 to the left and right, the diaphragm rubber 8a, which is a supporting means of the mover 3,
8b vibrates and, for example, when the mover 3 moves leftward, the volume of the compression chamber 9b on the right side increases and the internal pressure decreases, so that the intake valve 11 opens and air flows into the compression chamber 9b. On the other hand, in the compression chamber 9a on the left side, the volume is reduced and the internal pressure is increased, so that the discharge valve 12 is opened and the air is discharged to the outside. When the diaphragm rubbers 8a and 8b move to the right in the opposite direction, the operation is the opposite of the above-described operation, and air is sucked in and discharged. Thus, the suction and discharge of air are performed by the vibration of the mover 3. Since both ends of the mover 3 are supported by the diaphragm rubbers 8a and 8b in a suspended state, the mover 3 can vibrate without being worn due to the absence of sliding parts, and the service life can be extended.

Since the movable element is arranged so as to be movable in a direction orthogonal to the side surface and both ends of the mover are supported by vibrating supporting means, an air gap that does not have a variation in the air gap during assembly and a variation in the discharge air amount can be obtained. It has a configurable effect. Moreover, since the mover is movably arranged in the air gap in the direction orthogonal to the core side face as described above, and both ends of the mover are vibratably supported by the supporting means, the dimension of the mover in the vibration direction is as follows. The pump device can be made compact and the size of the pump device can be reduced, and the bending torque to the frame of the mover due to the attractive force applied to the permanent magnet can be reduced to reduce the mover's frame. The weight of the frame can be reduced, the driving force can be increased, and a highly efficient device can be realized. Moreover, the vibration direction of the mover is made orthogonal to the side surface of the core to reduce the laminated thickness of the core. It is possible to reduce the size and weight of the pump.
