（第１の実施形態）
本発明の第１の実施形態に係るチューブポンプについて図１乃至図４を参照して説明する。これらの図において、チューブポンプ１は、円筒室２が形成されたハウジング３と、チューブ４と、加圧部材５と、偏芯ロータ６と、モータ７と、ハウジング３の開口面を覆うカバー８とを備える。チューブ４は、円筒室２の内壁面２１に沿わせてリング状に配置され、一端に流体の流入口４１、他端に流体の流出口４２を有する。加圧部材５は、チューブ４のリング状内側に設けられ、チューブ４を円筒形の内壁面２１に対して圧迫するリング状の部材である。偏芯ロータ６は、リング状の加圧部材５に内接する円形部材であり、加圧部材５を内壁面２１に沿って偏芯運動させる。モータ７は、偏芯ロータ６を回転するものであり、モータ軸７１が偏芯ロータ６にその円形中心から偏芯して取り付けられる。カバー８は、例えば、蝶番９によりハウジング３と連結され、ハウジング３に対して開閉自在に設けられる。 (First embodiment)
A tube pump according to a first embodiment of the present invention will be described with reference to FIGS. In these drawings, the tube pump 1 includes a housing 3 in which a cylindrical chamber 2 is formed, a tube 4, a pressurizing member 5, an eccentric rotor 6, a motor 7, and a cover 8 that covers the opening surface of the housing 3. With. The tube 4 is arranged in a ring shape along the inner wall surface 21 of the cylindrical chamber 2, and has a fluid inlet 41 at one end and a fluid outlet 42 at the other end. The pressure member 5 is a ring-shaped member that is provided inside the ring 4 of the tube 4 and presses the tube 4 against the cylindrical inner wall surface 21. The eccentric rotor 6 is a circular member that is inscribed in the ring-shaped pressure member 5, and causes the pressure member 5 to move eccentrically along the inner wall surface 21. The motor 7 rotates the eccentric rotor 6, and the motor shaft 71 is attached to the eccentric rotor 6 so as to be eccentric from the center of the circle. The cover 8 is connected to the housing 3 by, for example, a hinge 9 and is provided so as to be openable and closable with respect to the housing 3.

円筒室２は、半円周よりも大きく、全円周よりも小さな内壁面２１を有し、内壁面２１が形成されていない間隙部分は、ハウジング３外に連通されてチューブ４の引き出し口となっている。ハウジング３は、例えばＡＢＳ樹脂等の成形品により構成され、円筒室２との連通部分には、チューブ４の両端部分を保持するための溝部１０が形成されている。   The cylindrical chamber 2 has an inner wall surface 21 that is larger than a semicircular circumference and smaller than the entire circumference, and a gap portion in which the inner wall surface 21 is not formed communicates with the outside of the housing 3 and is connected to the outlet of the tube 4. It has become. The housing 3 is formed of a molded product such as ABS resin, and a groove portion 10 for holding both end portions of the tube 4 is formed in a communicating portion with the cylindrical chamber 2.

チューブ４は、送出する流体に応じて選定された可撓性材料、例えばゴム又は合成樹脂から成り、円筒室２の内壁面２１に沿うようにリング（開環形）状に配置される。チューブ４の両端（流入口４１及び流出口４２）は、溝部１０を経てハウジング３外に延出され、配管（図示せず）を接続するためのニップル４１ａ，４２ａが設けられる。   The tube 4 is made of a flexible material selected according to the fluid to be delivered, such as rubber or synthetic resin, and is arranged in a ring (ring-opening shape) along the inner wall surface 21 of the cylindrical chamber 2. Both ends (inlet 41 and outlet 42) of the tube 4 are extended out of the housing 3 through the groove 10, and nipples 41a and 42a for connecting pipes (not shown) are provided.

加圧部材５は、摩擦係数が小さい材料を、平面視形状が円環で一定厚のリング状に形成して成り、例えば、フッ素樹脂系の合成樹脂成形品により構成される。加圧部材５は、偏芯ロータ６が加圧部材５の内周面に摺接して回転することにより、チューブ４の一部を内壁面２１に対し圧迫する。チューブ４において、図１の下側に示される圧迫部分は、チューブ４内の流路が閉塞され、図１の下側に示される非圧迫部分は、流路が確保される。   The pressing member 5 is formed by forming a material having a small friction coefficient into a ring shape having a circular shape in plan view and a constant thickness, and is made of, for example, a fluororesin-based synthetic resin molded product. The pressurizing member 5 presses a part of the tube 4 against the inner wall surface 21 when the eccentric rotor 6 rotates in sliding contact with the inner peripheral surface of the pressurizing member 5. In the tube 4, the compression portion shown on the lower side of FIG. 1 blocks the flow path in the tube 4, and the non-compression portion shown on the lower side of FIG.

モータ７は、小型の直流モータであり、チューブポンプ１外の直流電源（図示せず）から給電される。チューブポンプ１に電池を内蔵してモータ７に給電するように構成してもよい。ここではモータ７が、ハウジング３の偏芯ロータ６が取り付けられた反対面側（背面側）にあって、モータ軸７１がハウジング３の開口３ａを通して偏芯ロータ６に固定されている。   The motor 7 is a small DC motor and is supplied with power from a DC power source (not shown) outside the tube pump 1. A battery may be built in the tube pump 1 to supply power to the motor 7. Here, the motor 7 is on the opposite side (rear side) of the housing 3 to which the eccentric rotor 6 is attached, and the motor shaft 71 is fixed to the eccentric rotor 6 through the opening 3 a of the housing 3.

モータ７の回転は偏芯ロータ６に伝達され、偏芯ロータ６の回転によって加圧部材５が偏芯運動することにより、チューブ４の圧迫部分が一方向に移動し、チューブ４内の流体が送出される。このようなポンプ作用により、流体が流入口４１に流入し、流出口４２から流出する。   The rotation of the motor 7 is transmitted to the eccentric rotor 6, and the pressing member 5 moves eccentrically by the rotation of the eccentric rotor 6, so that the compressed portion of the tube 4 moves in one direction, and the fluid in the tube 4 moves. Sent out. By such a pump action, the fluid flows into the inflow port 41 and flows out from the outflow port 42.

本実施形態においてチューブポンプ１は、チューブ４を円筒室２の内壁面２１と加圧部材５との間に挿入する際に用いられるチューブ押さえ部材１１と、チューブ挿入時にチューブ４を内壁面２１に臨むように位置保持させるセット部材１２とを備える。セット部材１２は、内壁面２１の円筒直径より小径で、その円筒中心と同心状に配置された円筒部材であり、偏芯ロータ６とハウジング３の開口面側から接するようにモータ軸７１に固定される。これにより、セット部材１２と内壁面２１との間には、チューブ４のリング状部４ａをチューブ挿入時に一時的に位置保持するための空間が形成される。チューブ押さえ部材１１は、セット部材１２と内壁面２１との間に位置保持されたチューブ４のリング状部４ａとハウジング３の開口面側から当接可能にセット部材１２に取り付けられ、偏芯ロータ６と共に回転する。チューブ押さえ部材１１は、セット部材１２の周方向に延びるバー形状を成し、セット部材１２において偏芯ロータ６の内壁面２１に対する対向間隔が広がる反偏芯方向となる部分（モータ軸７１側）に配置される。チューブ押さえ部材１１の一端側は、セット部材１２の溝１２ａに上下に旋回自在に保持され、他端側は、チューブ４のリング状部４ａを押し込むための当接部１１ａとなっている。当接部１１ａはチューブ４から離れる方向に旋回させることができるので、装着されたチューブ４を離脱し易くなる。ここにカバー８には、カバー８を閉じた状態で、チューブ押さえ部材１１の当接部１１ａに押し当てられるように接する凸部８ａが設けられている。この凸部８ａは、当接部１１ａが回転されるときの回転軌跡に沿うような円環状に形成される。   In the present embodiment, the tube pump 1 includes a tube pressing member 11 that is used when the tube 4 is inserted between the inner wall surface 21 of the cylindrical chamber 2 and the pressure member 5, and the tube 4 that is placed on the inner wall surface 21 when the tube is inserted. And a set member 12 that holds the position so as to face. The set member 12 is a cylindrical member that is smaller in diameter than the cylindrical diameter of the inner wall surface 21 and is concentrically arranged with the center of the cylinder, and is fixed to the motor shaft 71 so as to be in contact with the eccentric rotor 6 from the opening surface side of the housing 3. Is done. Thereby, a space is formed between the set member 12 and the inner wall surface 21 to temporarily hold the ring-shaped portion 4a of the tube 4 when the tube is inserted. The tube pressing member 11 is attached to the set member 12 so as to be able to come into contact with the ring-shaped portion 4a of the tube 4 held between the set member 12 and the inner wall surface 21 from the opening surface side of the housing 3, and the eccentric rotor. 6 and rotate. The tube pressing member 11 has a bar shape extending in the circumferential direction of the set member 12, and a portion of the set member 12 that is in an anti-eccentric direction in which the facing distance to the inner wall surface 21 of the eccentric rotor 6 is widened (on the motor shaft 71 side). Placed in. One end side of the tube pressing member 11 is held in the groove 12a of the set member 12 so as to be pivotable up and down, and the other end side is an abutting portion 11a for pushing the ring-shaped portion 4a of the tube 4. Since the contact part 11a can be swung in a direction away from the tube 4, the attached tube 4 can be easily detached. Here, the cover 8 is provided with a convex portion 8 a that comes into contact with the contact portion 11 a of the tube pressing member 11 in a state where the cover 8 is closed. The convex portion 8a is formed in an annular shape along the rotation locus when the contact portion 11a is rotated.

上記のように構成されたチューブポンプ１において、図２に示すように、チューブ装着時には、チューブ４の両端部分をハウジング３の溝部１０に嵌め込み、チューブ４のリング状部４ａを円筒形の内壁面２１とセット部材１２との間にセットする。この状態では、チューブ４の引出部４ｂは溝部１０によって正規の位置に保持されるが、リング状部４ａはセット部材１２の周囲に一時的に保持されているだけであるので、引出部４ｂからリング状部４ａに連なる部分は斜めになっている。   In the tube pump 1 configured as described above, as shown in FIG. 2, when the tube is mounted, both end portions of the tube 4 are fitted into the groove portion 10 of the housing 3, and the ring-shaped portion 4a of the tube 4 is formed into a cylindrical inner wall surface. 21 and the set member 12 are set. In this state, the lead-out portion 4b of the tube 4 is held at a normal position by the groove portion 10, but the ring-like portion 4a is only temporarily held around the set member 12, so that the pull-out portion 4b A portion connected to the ring-shaped portion 4a is inclined.

次に、図３に示すように、カバー８を閉じると、カバー８の凸部８ａによりチューブ押さえ部材１１の当接部１１ａが押し込まれ、チューブ４のリング状部４ａは当接部１１ａに押される。当接部１１ａが位置する箇所は、内壁面２１と加圧部材５との間に十分な隙間が生じている部分であるので、リング状部４ａは加圧部材５の外周付近まで挿入される。   Next, as shown in FIG. 3, when the cover 8 is closed, the contact portion 11a of the tube pressing member 11 is pushed in by the convex portion 8a of the cover 8, and the ring-shaped portion 4a of the tube 4 is pressed by the contact portion 11a. It is. Since the location where the contact portion 11 a is located is a portion where a sufficient gap is generated between the inner wall surface 21 and the pressure member 5, the ring-shaped portion 4 a is inserted to the vicinity of the outer periphery of the pressure member 5. .

このような状態で、偏芯ロータ６をモータ７により回転駆動させると、図４に示すように、チューブ押さえ部材１１が偏芯ロータ６と共に回転され、これに伴って内壁面２１と加圧部材５との間に生じている隙間の位置が移動するので、チューブ４のリング状部４ａは当接部１１ａによって内壁面２１と加圧部材５との間に順次押し込まれる。最終的に偏芯ロータ６が略１回転すると、チューブ４のリング状部４ａが引出部４ｂの延長線上の位置、すなわち、正しく装着された場合の正規の位置に達してチューブ４の装着が完了する。   When the eccentric rotor 6 is rotationally driven by the motor 7 in such a state, the tube pressing member 11 is rotated together with the eccentric rotor 6 as shown in FIG. Since the position of the gap formed between the inner wall surface 21 and the pressure member 5 is sequentially pushed by the contact portion 11a. When the eccentric rotor 6 finally rotates approximately once, the ring-shaped portion 4a of the tube 4 reaches the position on the extension line of the lead-out portion 4b, that is, the proper position when correctly mounted, and the mounting of the tube 4 is completed. To do.

このように本実施形態に係るチューブポンプ１によれば、偏芯ロータ６を回転させるだけでチューブ４がチューブ押さえ部材１１により内壁面２１と加圧部材５との間に順次押し込まれ、チューブ４を自動的に挿入することができるので、チューブ４の交換が容易になる。また、カバー８を開くとチューブ押さえ部材１１によるチューブ４への押し込みが解除されるので、装着したチューブ４を取り外し易い。   As described above, according to the tube pump 1 according to the present embodiment, the tube 4 is sequentially pushed between the inner wall surface 21 and the pressurizing member 5 by the tube pressing member 11 only by rotating the eccentric rotor 6. Can be automatically inserted, so that the tube 4 can be easily replaced. Further, when the cover 8 is opened, the pushing of the tube pressing member 11 into the tube 4 is released, so that the attached tube 4 can be easily removed.

（第２の実施形態）
本発明の第２の実施形態に係るチューブポンプについて図５乃至図９を参照して説明する。図５乃至図７において、本実施形態のチューブポンプ１は、チューブ押さえ部材１１がカバー８に回転自在に設けられ、カバー８を閉じた状態で偏芯ロータ６に連動して回転させられるように構成されている点で第１の実施形態と相違する。第１の実施形態と同等の箇所には同じ符号を付している。チューブ押さえ部材１１は、その一端側がカバー８の内面側に軸支され、他端側にチューブ４の方向に向けて突出形成された当接部１１ａを有する。セット部材１２には、カバー８を閉じた状態でチューブ押さえ部材１１にその側方から接する凸部１２ｂが設けられ、これにより、セット部材１２が偏芯ロータ６と共に回転されると、チューブ押さえ部材１１が凸部１２ｂにより押されて回転する。 (Second Embodiment)
A tube pump according to a second embodiment of the present invention will be described with reference to FIGS. 5 to 7, in the tube pump 1 of the present embodiment, the tube pressing member 11 is rotatably provided on the cover 8 and is rotated in conjunction with the eccentric rotor 6 with the cover 8 closed.

A tube pump according to a third embodiment of the present invention will be described with reference to FIGS. In these drawings, as shown in FIG. 10, the tube pump 1 according to the present embodiment includes a holding portion 13 that holds both ends of the tube 4 with the cover 8 open on the inner surface of the cover 8. When the cover 8 is closed with the tube 4 held by the cover 8 using the ring 13, the ring-shaped portion 4 a of the tube 4 faces the inner wall surface 21 of the housing 3. Here, the holding unit 13 holds the tube holder 43 connected to both ends of the tube 4 on the open end side of the cover 8. The tube holder 43 restrains both ends of the tube 4 so that the tube 4 has a predetermined ring shape. The holding portion 13 includes a pair of plate-like members opposed to each other, and one plate-like member is provided with a locking piece for locking the tube holder 43 inserted between the two plate-like members so as not to be detached. ing. A support member 14 that abuts the tube 4 held by the holding portion 13 and supports the tube 4 so as to be parallel to the opening surface of the housing 3 when the cover 8 is closed is provided on the inner surface of the cover 8. Is provided. The tube pressing member 11 is attached to the set member 12 so as to come into contact with the ring-shaped portion 4a of the tube 4 held around the set member 12 with the cover 8 closed, from the opening surface side of the housing 3, and is eccentric. It rotates with the rotor 6. One end side of the tube pressing member 11 is held in the groove 12a of the set member 12 so as to be pivotable up and down.

上記のように構成されたチューブポンプ１において、図１１に示すように、チューブ装着時には、カバー８を開いた状態にして、カバー８にチューブ４の両端にあるチューブホルダ４３を保持部１３を用いて保持させる。次に、図１２に示すように、カバー８を閉じていくと、カバー８に保持させたチューブ４のリング状部４ａがハウジング３側へと移動され、図１３に示すように、カバー８が完全に閉じられたとき、リング状部４ａが内壁面２１とセット部材１２との間にセットされる。このとき、カバー８の内面によってチューブ押さえ部材１１が押し込まれることにより、チューブ４のリング状部４ａの一部は、チューブ押さえ部材１１によって内壁面２１側に押下げられ、加圧部材５の外周付近まで挿入される。このような状態で、偏芯ロータ６が回転駆動されると、チューブ押さえ部材１１が偏芯ロータ６と共に回転され、これに伴って内壁面２１と加圧部材５との間に生じている隙間の位置が移動するので、チューブ４のリング状部４ａはチューブ押さえ部材１１によって内壁面２１と加圧部材５との間に順次押し込まれる（上述の図４参照）。最終的に偏芯ロータ６が略１回転すると、チューブ４のリング状部４ａは正規の位置まで達して、チューブ４の装着が完了する。   In the tube pump 1 configured as described above, as shown in FIG. 11, when the tube is mounted, the cover 8 is opened, and the tube holders 43 at both ends of the tube 4 are attached to the cover 8 using the holding portion 13. Hold. Next, as shown in FIG. 12, when the cover 8 is closed, the ring-shaped portion 4a of the tube 4 held by the cover 8 is moved to the housing 3 side, and as shown in FIG. When completely closed, the ring-shaped portion 4 a is set between the inner wall surface 21 and the set member 12. At this time, when the tube pressing member 11 is pushed by the inner surface of the cover 8, a part of the ring-shaped portion 4 a of the tube 4 is pushed down toward the inner wall surface 21 by the tube pressing member 11, and the outer periphery of the pressure member 5 Inserted to near. When the eccentric rotor 6 is rotationally driven in such a state, the tube pressing member 11 is rotated together with the eccentric rotor 6, and accordingly, a gap generated between the inner wall surface 21 and the pressure member 5. Therefore, the ring-shaped portion 4a of the tube 4 is sequentially pushed between the inner wall surface 21 and the pressure member 5 by the tube pressing member 11 (see FIG. 4 described above). When the eccentric rotor 6 finally rotates approximately once, the ring-shaped portion 4a of the tube 4 reaches the proper position, and the mounting of the tube 4 is completed.

チューブ４を取り外す際には、図１４に示すように、カバー８を開くと、保持部１３に保持されたチューブ４がカバー８と共に回転することにより、チューブ４のリング状部４ａが引き上げられて内壁面２１と加圧部材５との間から離脱される。   When removing the tube 4, as shown in FIG. 14, when the cover 8 is opened, the tube 4 held by the holding portion 13 rotates together with the cover 8, so that the ring-shaped portion 4 a of the tube 4 is pulled up. It is separated from between the inner wall surface 21 and the pressure member 5.

本実施形態に係るチューブポンプ１においても、上記の実施形態と同様に、チューブ４を自動的に挿入することが可能となり、チューブ４の交換が容易になる。また、保持部１３を用いてチューブ４をカバー８に保持させた状態でカバー８を閉じると、チューブ４のリング状部４ａが円筒形の内壁面２１とセット部材１２との間にセットされるので、チューブ４の装着作業が一層容易となる。   Also in the tube pump 1 according to the present embodiment, the tube 4 can be automatically inserted similarly to the above-described embodiment, and the tube 4 can be easily replaced. Further, when the cover 8 is closed while the tube 4 is held by the cover 8 using the holding portion 13, the ring-shaped portion 4 a of the tube 4 is set between the cylindrical inner wall surface 21 and the set member 12. Therefore, the mounting operation of the tube 4 becomes easier.
