Description
【０００１】[0001]
この考案はチュ−ブを複数のロ−ラによって順次押圧することで上記チュ−ブ の一端から流体を吸引し他端から突出させるチュ−ビングポンプに関する。 The present invention relates to a tubing pump that sucks fluid from one end of the tube and projects it from the other end by sequentially pressing the tube with a plurality of rollers.
【０００２】[0002]
チュ−ビングポンプは、たとえば医療現場や実験室において、薬液などのよう に油や金属によって汚染されることを嫌う流体を精密に輸送することが要求され る場合などに利用される。 The tubing pump is used, for example, in a medical field or a laboratory where it is required to precisely transport a fluid, such as a chemical solution, which is unlikely to be contaminated by oil or metal.
【０００３】 上記チュ−ビングポンプは周知のように、ロ−ラヘッドの外周部に複数のロ− ラが周方向に所定間隔で回転自在に設けられたポンプ機構を有する。このポンプ 機構には柔軟性を有するチュ−ブの中途部が上記ロ−ラヘドの外周面のほぼ半周 にわたって圧接して保持される。このチュ−ブの上記ポンプ機構よりも上流側の 部分と下流側の部分とは、それぞれ保持機構によって保持されている。As is well known, the tubing pump has a pump mechanism in which a plurality of rollers are provided on an outer peripheral portion of a roller head so as to be rotatable in a circumferential direction at predetermined intervals. A middle portion of the flexible tube is held in pressure contact with the pump mechanism over substantially half of the outer peripheral surface of the roller head. A portion of the tube upstream of the pump mechanism and a portion of the tube upstream of the pump mechanism are held by holding mechanisms.
【０００４】 上記ポンプ機構は、そのロ−ラで上記チュ−ブの中途部を順次押圧する。それ によって、上記チュ−ブの一端から流体を吸引し、他端から吐出させることにな る。上記保持機構は、上記チュ−ブを所定の押圧力で保持し、上記ポンプ機構に よりチュ−ブの中途部が繰返して押圧されても、そのチュ−ブが上記ロ−ラヘッ ドの回転方向にずれ動くのを阻止している。The pump mechanism sequentially presses the middle part of the tube with its roller. Thereby, the fluid is sucked from one end of the tube and discharged from the other end. The holding mechanism holds the tube with a predetermined pressing force, and even if the pump mechanism repeatedly presses the middle part of the tube, the tube keeps the direction of rotation of the roller head. It prevents it from moving.
【０００５】 図３（ａ）、（ｂ）と図４に従来のチュ−ブポンプを示す。同図中１は箱型に 形成され内部に図示しないモ−タや電気部品等が収容された本体である。この本 体１の前面にはポンプ機構２と、保持機構３とが設けられている。上記ポンプ機 構２は上記モ−タの回転軸４ａに着脱自在に取付けられたロ−ラヘッド４を有す る。このロ−ラヘッド４の周辺部には、その一部を上記ロ−ラヘッド４の外周面 から突出させた複数のロ−ラ５が回転自在に保持されている。3 (a), 3 (b) and FIG. 4 show a conventional tube pump. In the figure, reference numeral 1 denotes a main body which is formed in a box shape and accommodates a motor, electric parts and the like (not shown) therein. A pump mechanism 2 and a holding mechanism 3 are provided on the front surface of the main body 1. The pump mechanism 2 has a roller head 4 which is detachably attached to the rotary shaft 4a of the motor. A plurality of rollers 5, some of which are protruded from the outer peripheral surface of the roller head 4, are rotatably held on the peripheral portion of the roller head 4.
【０００６】 上記ロ−ラヘッド４の下側にはほぼ半円弧状のチュ−ブ受皿６の両端部が固定 ねじ７によって固定されている。この固定ねじ７をゆるめることで、上記チュ− ブ受皿６は上下方向にスライドさせることができるようになっている。このチュ −ブ受皿６と上記ロ−ラヘッド４の外周面との間には柔軟性を有するチュ−ブ８ の中途部が挿入される。On the lower side of the roller head 4, both ends of a tube tray 6 having a substantially semi-arcuate shape are fixed by fixing screws 7. The tube tray 6 can be slid vertically by loosening the fixing screw 7. An intermediate portion of the flexible tube 8 is inserted between the tube tray 6 and the outer peripheral surface of the roller head 4.
【０００７】 上記本体１の前面の上記チュ−ブ受皿６の下方には固定板９が突設されている 。この固定板９には調節ねじ１０が上下方向に進退可能に螺合されている。この 調節ねじ１０の上端にはＵ字状の押し金具１１が取付けられている。したがって 、上記固定ねじ７をゆるめて上記押し金具１１を上昇させれば、上記チュ−ブ受 皿６を上昇させることができる。それによって、上記チュ−ブ８の中途部が上記 ロ−ラ５に押圧される力を調節できるようになっている。A fixing plate 9 is projectingly provided on the front surface of the main body 1 below the tube receiving tray 6. An adjusting screw 10 is screwed onto the fixing plate 9 so as to be able to move forward and backward. A U-shaped push fitting 11 is attached to the upper end of the adjusting screw 10. Therefore, the tube tray 6 can be raised by loosening the fixing screw 7 and raising the push fitting 11. Thereby, the force with which the middle part of the tube 8 is pressed by the roller 5 can be adjusted.
【０００８】 チュ−ブ８の中途部をポンプ機構２に挿入し、ロ−ラ５に圧接させた状態で、 上記ロ−ラヘッド４を回転させれば、そのチュ−ブ８の中途部が複数のロ−ラ５ によって順次押圧されるから、そのチュ−ブ８の一端から流体を吸引し、他端か ら吐出させることができるようになっている。If the roller head 4 is rotated in a state where the tube 8 is inserted into the pump mechanism 2 and is pressed against the roller 5, the tube 8 has a plurality of intermediate portions. Since it is sequentially pressed by the roller 5, the fluid can be sucked from one end of the tube 8 and discharged from the other end.
【０００９】 上記ロ−ラヘッド４の上方両側には、上記チュ−ブ８の上記ポンプ機構２に挿 入された部分よりも上流側の部分と下流側の部分を、それぞれ保持する上記保持 機構３が設けられている。この保持機構３は図４に示すように上記本体１の前面 に一辺が固定された固定部材１２と、この固定部材１２の他辺に一対の締付けね じ１３によって取付けられた保持部材１４とからなる。On both upper sides of the roller head 4, the holding mechanism 3 for holding a portion of the tube 8 on the upstream side and a portion on the downstream side of the portion inserted into the pump mechanism 2 respectively. Is provided. As shown in FIG. 4, the holding mechanism 3 includes a fixing member 12 whose one side is fixed to the front surface of the main body 1 and a holding member 14 which is attached to the other side of the fixing member 12 by a pair of tightening screws 13. Become.
【００１０】 上記保持部材１４には、溝幅が上記チュ−ブ８の外径寸法よりも小さなＶ溝１ ５が形成されている。各保持部材１４のＶ溝１５には、上記チュ−ブ８の上記ポ ンプ機構２から導出された上流側と下流側の部分がそれぞれ挿入され、上記締付 けねじ１３を締付けることで、上記チュ−ブ８はその通路が確保される範囲内で 径方向に圧縮されて保持固定されている。それによって、チュ−ブ８が上記ロ− ラ５によって順次押圧されても、ロ−ラヘッド４の回転方向にずれ動くのが阻止 される。A V-groove 15 having a groove width smaller than the outer diameter of the tube 8 is formed on the holding member 14. The upstream and downstream portions of the tube 8 derived from the pump mechanism 2 are inserted into the V-grooves 15 of the holding members 14, respectively, and the tightening screw 13 is tightened to move the above-mentioned parts. The tube 8 is radially compressed and held and fixed within the range where the passage is secured. As a result, even if the tube 8 is sequentially pressed by the roller 5, the roller head 4 is prevented from shifting in the rotational direction.
【００１１】 ところで、このような構成のチュ−ビングポンプを使用するに際し、使用者が チュ−ブ８のポンプ機構２から導出された部分を保持機構３に保持固定するため には、締付けねじ１３をゆるめ、保持部材１４のＶ溝１５にチュ−ブ８を挿通し たならば、その挿通状態を一方の手で保持しながら他方の手で上記締め付けねじ １３を締め込まなければならない。By the way, when using the tubing pump having such a structure, in order for the user to hold and fix the portion of the tube 8 derived from the pump mechanism 2 to the holding mechanism 3, the tightening screw 13 When the tube 8 is inserted into the V-shaped groove 15 of the holding member 14 with one hand held, the tightening screw 13 must be tightened with the other hand while holding the inserted state.
【００１２】 そのため、チュ−ブ８を保持固定するためには、チュ−ブ８をＶ溝１５に挿通 する作業と、締付けねじ１３を締め込む作業との２つの作業が必要となり、しか も一方の手で上記チュ−ブ８の挿通状態を保持し、他方の手で締付けねじ１３を 締め込むという、両手を使う作業となるから、これらのことにより、作業性が悪 いということがあった。 また、使用後にチュ−ブ８を保持機構３から取外す際にも、締付けねじ１３を ゆるめなければならないから、その作業が煩雑になるということがある。Therefore, in order to hold and fix the tube 8, it is necessary to perform two operations, that is, the operation of inserting the tube 8 into the V groove 15 and the operation of tightening the tightening screw 13. Since the work of holding the tube 8 with one hand is held and the tightening screw 13 is tightened with the other hand, the work requires the use of both hands, which may result in poor workability. . Also, when the tube 8 is removed from the holding mechanism 3 after use, the tightening screw 13 must be loosened, which may complicate the work.
【００１３】[0013]
このように、従来のチュ−ビングポンプにおいては、チュ−ブのポンプ機構か ら導出された部分を保持固定するための保持機構がねじ締め構造であるため、そ の締付け作業や取外し作業を容易かつ迅速に行うことができないということがあ った。 As described above, in the conventional tubing pump, since the holding mechanism for holding and fixing the part of the tube that is led out from the pump mechanism has the screw tightening structure, the tightening work and the removing work can be easily performed. And it was not possible to do it quickly.
【００１４】 この考案は上記事情に基づきなされたもので、その目的とするところは、チュ −ブのポンプ機構から導出された部分の保持固定や取外しを容易かつ迅速に、し かも片手で楽に行うことができるようにしたチュ−ビングポンプを提供すること にある。The present invention has been made based on the above circumstances, and the purpose thereof is to easily and quickly hold or fix the portion of the tube which is led out from the pump mechanism, or easily with one hand. The purpose is to provide a tubing pump that is capable of doing so.
【００１５】[0015]
上記課題を解決するためにこの考案は、柔軟性を有するチュ−ブの中途部を複 数のロ−ラで順次押圧して流体を吸引吐出させるポンプ機構および上記チュ−ブ の上記ポンプ機構よりも上流側と下流側の部分とをそれぞれ保持する保持機構と を具備したチュ−ビングポンプにおいて、上記保持機構は、互いに凸曲面を有し これらの凸曲面の頂部を接合させた一対の保持体と、各保持体の凸曲面の周辺部 の対向する部位にそれぞれ突設され上記一対の凸曲面間に圧入された上記チュ− ブが外れるのを阻止する係止突起からなることを特徴とする。 In order to solve the above-mentioned problems, the present invention comprises a pump mechanism for sucking and discharging a fluid by sequentially pressing a middle portion of a flexible tube with a plurality of rollers, and a pump mechanism for the tube. In a tubing pump having a holding mechanism for respectively holding the upstream side portion and the downstream side portion, the holding mechanism has a convex curved surface and a pair of holding bodies in which the tops of these convex curved surfaces are joined. And a retaining protrusion that is provided at a peripheral portion of the convex curved surface of each holding body so as to project, and that prevents the tube press-fitted between the pair of convex curved surfaces from coming off. .
【００１６】[0016]
上記構成によれば、チュ−ブのポンプ機構から導出された部分を、一対の保持 体の対向する凸曲面間に挿入して周方向に巻き込めば、径方向内方にゆくにした がって間隔が次第に狭くなる一対の凸曲面によりチュ−ブが押圧挟持され、しか も上記凸曲面間に巻き込まれたチュ−ブは、復元力によって復元して上記凸曲面 間から外れるのが係止突起によって防止される。 According to the above configuration, when the portion of the tube that is led out from the pump mechanism is inserted between the convex curved surfaces of the pair of holding bodies and is wound in the circumferential direction, the tube is guided inward in the radial direction. The tube is pressed and sandwiched by a pair of convex curved surfaces with gradually narrowing intervals, and the tube caught between the convex curved surfaces is restored by the restoring force and comes out of the convex curved surface. Is prevented by.
【００１７】[0017]
以下、この考案の一実施例を図１（ａ）、（ｂ）と図２（ａ）、（ｂ）を参照 して説明する。なお、図３（ａ）、（ｂ）と図４に示す従来構造と同一部分には 同一記号を付して説明を省略する。 An embodiment of the present invention will be described below with reference to FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b). Incidentally, the same parts as those of the conventional structure shown in FIGS. 3A and 3B and FIG.
【００１８】 この考案においては、中途部がポンプ機構２によって保持されたチュ−ブ８の 、上記ポンプ機構２から導出された部分を保持するための保持機構の構成が従来 構造と異なる。In the present invention, the structure of the holding mechanism for holding the portion of the tube 8 held by the pump mechanism 2 at the midway portion and led out from the pump mechanism 2 is different from the conventional structure.
【００１９】 すなわち、この考案における一対の保持機構２１は、上記本体１の上面前端部 の幅方向両端部にそれそれぞれ設けられた、下部保持体２２と上部保持体２３と からなる。各保持体２２、２３は、弾力性を有するポリプロピレンや弗素樹脂な どの合成樹脂によってたとえば球面からなる凸曲面２２ａ、２３ａを有する中空 円盤状に形成されている。That is, the pair of holding mechanisms 21 in the present invention is composed of a lower holding body 22 and an upper holding body 23, which are provided at both widthwise ends of the front end of the upper surface of the main body 1. Each of the holders 22 and 23 is formed of a synthetic resin such as elastic polypropylene or fluororesin into a hollow disk shape having convex curved surfaces 22a and 23a formed of, for example, spherical surfaces.
【００２０】 上記一対の保持体２２、２３は、径方向中心部である、互いの凸曲面２２ａ、 ２３ａの頂部を接合させるとともに、その中心部に形成された通孔２２ｂ、２３ ｂに固定ねじ２４を通し、その固定ねじ２４を上記本体１の上面に捩じ込むこと で固定されている。それによって、一対の保持体２２、２３の対向する凸曲面２ ２ａ、２３ａの間隔は、径方向中心部にゆくにしたがって次第に狭くなる、挟持 部２５を形成している。 なお、一対の保持体２２、２３は２本以上の固定ねじ２４によって本体１に固 定するようにしてもよい。The pair of holding bodies 22 and 23 joins the tops of the convex curved surfaces 22a and 23a, which are the central portions in the radial direction, and fix the fixing screws to the through holes 22b and 23b formed in the central portions. It is fixed by passing through 24 and screwing the fixing screw 24 into the upper surface of the main body 1. As a result, the interval between the convex curved surfaces 22a and 23a of the pair of holding bodies 22 and 23 facing each other forms a sandwiching portion 25 that gradually narrows toward the central portion in the radial direction. The pair of holders 22 and 23 may be fixed to the main body 1 by two or more fixing screws 24.
【００２１】 上記一対の保持体２２、２３の凸曲面２２ａ、２３ａの径方向周辺部分には、 それぞれほぼ半球形状の係止突起２２ｃ、２３ｃが対応する部位に突設されてい る。一対の保持体２２、２３が固定された状態において、上記係止突起２２ｃ、 ２３ｃの先端間には、上記チュ−ブ８の外径寸法よりも小さな隙間２６、たとえ ばチュ−ブ８を偏平になるまで圧縮変形させたときの厚さよりもわずかに大きな 隙間２６が形成される。On the peripheral portions in the radial direction of the convex curved surfaces 22a and 23a of the pair of holding bodies 22 and 23, substantially hemispherical locking protrusions 22c and 23c are provided so as to project at corresponding portions. With the pair of holders 22 and 23 fixed, a gap 26 smaller than the outer diameter of the tube 8 such as the tube 8 is flat between the tips of the locking projections 22c and 23c. A gap 26 that is slightly larger than the thickness when it is compressed and deformed until is formed.
【００２２】 上記構成のチュ−ビングポンプを使用する場合には、まず、調節ねじ１０をゆ るめてポンプ機構２を構成するチュ−ブ受け皿６を下降させ、このチュ−ブ受け 皿６とロ−ラヘッド４との間にチュ−ブ８の中途部を挿通する。ついで、チュ− ブ受け皿６を上昇させてチュ−ブ８を所定の圧力でロ−ラ５に圧接させて保持す る。In the case of using the tube pump having the above structure, first, the adjusting screw 10 is swung to lower the tube receiving tray 6 constituting the pump mechanism 2, and the tube receiving tray 6 is An intermediate part of the tube 8 is inserted between the roller head 4 and the roller head 4. Then, the tube receiving tray 6 is raised and the tube 8 is held in pressure contact with the roller 5 at a predetermined pressure.
【００２３】 つぎに、上記ポンプ機構２のロ−ラヘッド４の外周面から導出されたチュ−ブ ８の一端部側を一方の保持機構２１の一対の保持体２２、２３間の挟持部２５に 挿入し、一対の係止突起２２ｃ、２３ｃの隙間２６を通るまで、上記保持体２２ 、２３の径方向内方へ押付けながら周方向に沿って巻回する。それによって、チ ュ−ブ８は、径方向内方に向かって漸次間隔が狭くなる一対の凸曲面２２ａ、２ ３ａにより弾性的に圧縮されて挟持されるとともに、一対の係止突起２２ｃ、２ ３ｃの先端間の隙間２６を通されることで、挟持部２５に巻回された湾曲状態が 復元するのが防止される。つまり、チュ−ブ８の上記挟持部２５に装着された部 分は、上記係止突起２２ｃ、２３ｃによって図２（ａ）に鎖線８´で示すように 復元して挟持部２５から外れるのが防止される。Next, one end side of the tube 8 drawn out from the outer peripheral surface of the roller head 4 of the pump mechanism 2 is used as a holding portion 25 between the pair of holding bodies 22 and 23 of the one holding mechanism 21. It is inserted and pressed along the circumferential direction while being pressed inward in the radial direction of the holding bodies 22 and 23 until it passes through the gap 26 between the pair of locking projections 22c and 23c. As a result, the tube 8 is elastically compressed and sandwiched by the pair of convex curved surfaces 22a, 23a having a gradually decreasing distance inward in the radial direction, and at the same time, the pair of locking projections 22c, 2c. By passing through the gap 26 between the tips of 3c, it is possible to prevent the curved state wound around the holding portion 25 from being restored. That is, the portion of the tube 8 mounted on the holding portion 25 is restored by the locking protrusions 22c and 23c as shown by the chain line 8'in FIG. To be prevented.
【００２４】 上記挟持部２６は一対の凸曲面２２ａ、２３ａによって形成された間隔が次第 に狭くなるよう形成されているから、そこに挟持されるチュ−ブ８が流体の流通 が不能となるまでその通路が押し潰されるということがない。Since the sandwiching portion 26 is formed such that the interval formed by the pair of convex curved surfaces 22a and 23a becomes gradually narrower, until the tube 8 sandwiched there becomes incapable of fluid flow. The passage is never crushed.
【００２５】 つまり、チュ−ブ８は一対の保持体２２、２３の凸曲面２２ａ、２３ａがなす 挟持部２５に挟持されるとともに、その挟持状態が係止突起２２ｃ、２３ｃによ って確実に維持される。しかも、上記保持体２２、２３は弾性材料で作られ、チ ュ−ブ８は柔軟な材料で作られていることにより、チュ−ブ８を挟持部２６に巻 着する際、保持体２２、２３が弾性変形し、挟持部２５の隙間が拡げられながら チュ−ブ８が一対の凸曲面２２ａ、２３ａに挟持されるから、その挟持状態が上 記保持体２２、２３の復元力によって確実に維持される。 このように、チュ−ブ８の一端部側を一対の保持体２２、２３の挟持部２５に 挟持させたなら、他端部側も同様に挟持させればよい。That is, the tube 8 is sandwiched by the sandwiching portion 25 formed by the convex curved surfaces 22a, 23a of the pair of holding bodies 22, 23, and the sandwiched state is securely held by the locking projections 22c, 23c. Maintained. Moreover, since the holders 22 and 23 are made of an elastic material and the tube 8 is made of a flexible material, when the tube 8 is wound around the holding portion 26, the holders 22, 23 is elastically deformed, and the tube 8 is clamped by the pair of convex curved surfaces 22a and 23a while the gap of the clamp portion 25 is expanded. Maintained. In this way, if one end side of the tube 8 is held between the holding portions 25 of the pair of holding bodies 22 and 23, the other end side may be held similarly.
【００２６】 すなわち、上記構成の保持機構２１によれば、中途部がポンプ機構２に保持さ れたチュ−ブ８の、上記ポンプ機構２から導出されたチュ−ブ８一端部側と他端 部側とを順次、片方の手で握持して一対の保持体２２、２３間の挟持部２５に巻 回させるだけでよいから、作業者はチュ−ブ８を巻回させるだけの簡単な作業で そのチュ−ブ８を確実に保持させることができ、しかもその作業を片手で容易に 行うことができる。That is, according to the holding mechanism 21 having the above-described configuration, the tube 8 whose halfway portion is held by the pump mechanism 2 has one end and the other end of the tube 8 led out from the pump mechanism 2. It is only necessary to grip the section side with one hand and wind it around the sandwiching section 25 between the pair of holding bodies 22 and 23, so that the operator simply winds the tube 8. The tube 8 can be securely held by the work, and the work can be easily performed with one hand.
【００２７】 上記チュ−ブ８を保持機構２１から取外す際には、チュ−ブ８を片手で握持し 、上記チュ−ブ８を挟持部２５から外す方向に引張ればよい。つまり、チュ−ブ ８を各保持体２２、２３の凸曲面２２ａ、２３ａとの圧接力に抗して引張るだけ でよいから、その取外し作業も、取付け作業と同様、片手で容易に行うことがで きる。When detaching the tube 8 from the holding mechanism 21, the tube 8 may be gripped with one hand and pulled in a direction in which the tube 8 is detached from the holding portion 25. In other words, since it is only necessary to pull the tube 8 against the pressure contact force with the convex curved surfaces 22a and 23a of the holders 22 and 23, the detaching work can be easily performed with one hand as in the attaching work. it can.
【００２８】 なお、上記一実施例では、一対の保持体を別体構造としたが、成形加工あるい は切削加工によって一体構造としてもよい。さらに、保持体を形成する材料は合 成樹脂に限られず、金属や木など他の材料で作るようにしてもよい。In addition, in the above-mentioned one embodiment, the pair of holding bodies has a separate structure, but they may have an integral structure by molding or cutting. Further, the material forming the holder is not limited to the synthetic resin, and may be made of other material such as metal or wood.

以上述べたようにこの考案は、チュ−ビングポンプにおいて、チュ−ブの中途 部をポンプ機構に保持し、このポンプ機構から導出されたチュ−ブの上流側と下 流側とをそれぞれ保持する保持機構を、凸曲面を有しこれらの凸曲面の頂部を接 合させた一対の保持体と、各保持体の凸曲面の周辺部の対向する部位にそれぞれ 突設され上記一対の凸曲面間に圧入された上記チュ−ブが外れるのを阻止する係 止突起から構成した。 As described above, according to the present invention, in the tubing pump, the middle part of the tube is held by the pump mechanism, and the upstream side and the downstream side of the tube led out from the pump mechanism are respectively held. The holding mechanism has a pair of holding bodies having convex curved surfaces and the tops of these convex curved surfaces are joined to each other, and the holding mechanism is provided between the pair of convex curved surfaces projecting at opposite portions of the peripheral portions of the convex curved surfaces of each holding body. It is composed of a locking projection that prevents the tube press-fitted into the tube from coming off.
【００３０】 そのため、上記チュ−ブを上記一対の凸曲面間に巻き込むだけで、保持できる から、その取付け作業および取外し作業を容易かつ迅速に、しかも片手で簡単に 行うことができるという利点を有する。Therefore, since the tube can be held only by winding it between the pair of convex curved surfaces, there is an advantage that the mounting work and the removing work can be performed easily and quickly and easily with one hand. .
