【従来の技術】[Prior art]

２分の１以上の円形部を有する空洞部材の空洞壁にチユーブを添わせ、該チユ ーブの内側にリング状部材を遊動自在に配置し、リング状部材の内側に沿って偏 芯軸を回転させて、リング状部材を介してチユーブを順次圧迫してチユーブの中 の液体を送出した。 そして、偏芯軸を回転させることによって、円形部の終端部に於いて、リング 状部材と空洞部材の間隙を狭小ならしめて、チユーブの流入口側と流出口側を閉 止せしめる如く、リング状部材と空洞部材及び偏芯軸の関係寸法を設定した。 上記の構成に於いて、偏芯軸が、円形部の終端部の略中央方向に位置した時も 、チユーブが閉止されて逆流を防止し、液体を同一方向に送出出来るものである 。 A tube is attached to the cavity wall of a cavity member having a half or more circular portion, a ring-shaped member is movably arranged inside the tube, and an eccentric shaft is arranged along the inside of the ring-shaped member. The tube was rotated, and the tubes were successively pressed through the ring-shaped member to deliver the liquid in the tubes. Then, by rotating the eccentric shaft, the gap between the ring-shaped member and the hollow member is narrowed at the end of the circular portion, so that the inlet side and the outlet side of the tube are closed. The relational dimensions of the member, the hollow member, and the eccentric shaft were set. In the above structure, even when the eccentric shaft is located in the substantially central direction of the end portion of the circular portion, the tube is closed to prevent backflow and the liquid can be delivered in the same direction.

【考案が解決しようとする課題】[Problems to be solved by the device]

チユーブの流入口側と流出口側を閉止せしめる為には、円形部の終端部の両側 に凸部を設けてリング状部材でチユーブを凸部に圧迫する、或は、リング状部材 が円形部の終端部方向に移動する寸法を他の円形部方向よりも大ならしめる等の 方法がある。 しかしながら、これらの方法によると、リング状部材が、円弧運動、又は回転 運動をする為に、チユーブの流入口側では圧迫力が大きくなるので、流入口側と 流出口側の夫々の関係寸法を調整する必要があり、又、高い寸法精度を必要とし た。 従って、円形部の終端部及び周囲に於いて、チユーブに均一な圧力を加えるこ とが困難であった。このために、チユーブの一部に他よりも大なる力が加わって チユーブの耐久性を劣化させ、又、圧迫力が不均一になる為にモータの負荷が変 動してモータの寿命を短縮させた。 In order to close the inlet side and outlet side of the tube, provide convex parts on both sides of the end of the circular part and press the tube on the convex part with a ring-shaped member, or if the ring-shaped member has a circular part. There is a method such as making the dimension of moving in the direction of the terminal end of the larger than in the direction of other circular parts. However, according to these methods, since the ring-shaped member makes an arc motion or a rotational motion, the compressive force becomes large on the inlet side of the tube, so that the relational dimensions on the inlet side and the outlet side are not determined. It needed to be adjusted and required high dimensional accuracy. Therefore, it has been difficult to apply uniform pressure to the tube at the end of the circular portion and its periphery. For this reason, a larger force is applied to part of the tube than other parts, which deteriorates the durability of the tube, and the load on the motor changes due to uneven compression force, which shortens the life of the motor.

【課題を解決する為の手段】[Means for solving the problem]

リング状部材と空洞部材の間隙を狭小ならしめる位置に於いて、空洞部材の内 部に適当な空洞部を穿ち、該位置に於いて、チユーブがリング状部材によって圧 迫されたときに、空洞部と空洞壁との間の弾力性によってチユーブが適切な圧迫 力を受けられるように構成する。 At the position where the gap between the ring-shaped member and the hollow member is narrowed, an appropriate hollow portion is bored inside the hollow member, and at that position, when the tube is pressed by the ring-shaped member, The elasticity between the section and the cavity wall allows the tube to receive an appropriate compression force.

【０００５】[0005]

【作用】[Action]

空洞部の寸法を選択して、空洞部と空洞壁の間の弾力性を適当に選定すること によって、チユーブに無理な圧迫力が加わることを防止出来、又、流入口側と流 出口側の空洞部を適当に選定して、円形部の全周にわたってチユーブに均一な圧 迫力を加えることが出来る。 By selecting the size of the cavity and selecting the elasticity between the cavity and the wall of the cavity appropriately, it is possible to prevent excessive compression force from being applied to the tube. By properly selecting the cavity, it is possible to apply uniform pressing force to the tube over the entire circumference of the circular part.

本考案の実施例を Embodiment of the present invention

【図１】に於いて説明する。 （イ）Ｕ字型の上部を絞って、首状部２を形成した首状空洞壁３を有する基板 １の首状空洞壁３に添わせてチユーブ４を配置する。 （ロ）チユーブ４の内側に、軸孔５を有し、基板１に固着された軸芯６に遊動 自在に取り付けた偏芯リング７を配置する。 （ハ）偏芯リング７の内側に接触して回転する偏芯軸８を設ける。 （ニ）偏芯リング７は、外側を円形とし、内側を偏芯させた楕円状の孔に形成 する。 該楕円状の孔の寸法は、偏芯軸８の長径が首状空洞壁３の首状部２の中央方向に 位置した時に、首状部２に於いて、偏芯リング７がチユーブ４を圧迫してチユー ブ４を閉止せしめ、次いで、偏芯軸８の長径が、首状部２以外の円形部の全周に 於いていずれに位置した時も、チユーブ４を閉止するように設定する。 （ホ）首状部２に近接して、基板１に空洞部９を穿つ。 以上、（イ）（ロ）（ハ）（ニ）（ホ）の構成に於いて、偏芯軸８を回転させる と、偏芯リング７は、軸芯６を軸として円弧運動を起こし、チユーブ４は偏芯軸 ８の回転方向に向かって順次圧迫されて、チユーブ４の中の液体が絞り出される 。FIG. 1 will be described. (A) The upper portion of the U-shape is squeezed, and the tube 4 is arranged along the neck-shaped cavity wall 3 of the substrate 1 having the neck-shaped cavity wall 3 in which the neck-shaped portion 2 is formed. (B) An eccentric ring 7 having a shaft hole 5 and rotatably attached to a shaft core 6 fixed to the substrate 1 is arranged inside the tube 4. (C) An eccentric shaft 8 that comes into contact with the inside of the eccentric ring 7 and rotates is provided. (D) The eccentric ring 7 is formed into an elliptical hole having a circular outer shape and an eccentric inner shape. The size of the elliptical hole is such that, when the major axis of the eccentric shaft 8 is located in the central direction of the neck-shaped portion 2 of the neck-shaped cavity wall 3, the eccentric ring 7 moves the tube 4 in the neck-shaped portion 2. Set to close the tube 4 by pressing it, and then close the tube 4 regardless of where the major axis of the eccentric shaft 8 is located on the entire circumference of the circular part other than the neck part 2. . (E) A cavity 9 is formed in the substrate 1 in the vicinity of the neck portion 2. As described above, in the configurations of (a), (b), (c), (d), and (e), when the eccentric shaft 8 is rotated, the eccentric ring 7 causes an arc motion with the shaft center 6 as an axis, and the tube is moved. 4 is squeezed sequentially in the direction of rotation of the eccentric shaft 8 to squeeze out the liquid in the tube 4.

【図１】は、偏芯軸８の長径が首状部２の中央方向に位置して、偏芯リング７ と首状部２の間隙が狭小になって、チユーブ４の流入部１０と流出部１１が同時 に閉止された状態を示すものであるが、この状態に於いて、首状部２と空洞部３ の間に形成された適度の弾力性を有する弾性部１２によって、チユーブ４に適切 な圧迫力が加わるように構成されている。 尚、流入部１０と流出部１１は偏芯軸８が時計方向に回転した場合を示すもので 、偏芯軸８が反時計方向に回転した時は、流入部１０と流出部１１は逆になる。 又、基板１を、適当な粘弾性材料で構成すれば、各部品の寸法誤差を吸収する ことが出来て、チユーブにより一層均一な圧迫力を加えることが出来る。 又、空洞部９に、適当な弾性材を挿入、或は充填して、弾性部１２の弾力性を 調整しても良い。1 shows that the major axis of an eccentric shaft 8 is located in the central direction of the neck-shaped portion 2, the gap between the eccentric ring 7 and the neck-shaped portion 2 is narrowed, and the inflow portion 10 and the outflow portion of the tube 4 flow out. The state in which the parts 11 are simultaneously closed is shown. In this state, the elastic part 12 having an appropriate elasticity formed between the neck-shaped part 2 and the hollow part 3 causes the tube 4 to move. It is configured to apply appropriate compression force. The inflow part 10 and the outflow part 11 show the case where the eccentric shaft 8 rotates clockwise. When the eccentric shaft 8 rotates counterclockwise, the inflow part 10 and the outflow part 11 are reversed. Become. Further, if the substrate 1 is made of an appropriate viscoelastic material, it is possible to absorb the dimensional error of each component and apply a more uniform pressing force to the tube. Further, the elasticity of the elastic portion 12 may be adjusted by inserting or filling an appropriate elastic material in the hollow portion 9.

【効果】【effect】

チユーブの特定部分に大きな圧迫力が加わることを防止出来て、尚且つ、基板 の円形部の全周にわたって均一な圧迫力を与えるように構成することが出来るの で、チユーブの耐久性を向上させ、又、モータに均一な負荷をかけることが出来 るので、モータを長寿命にすることが出来る。 It is possible to prevent a large amount of pressure from being applied to a specific part of the tube, and it is also possible to provide uniform pressure over the entire circumference of the circular portion of the board, improving the durability of the tube. Moreover, since a uniform load can be applied to the motor, the life of the motor can be extended.
