Description
本発明は、上記のように構成したことにより、リニア駆動機構によりプランジャをピストン駆動させて、液体をノズルチップ内等に吸入し、吐出するものでありながら、マグネットとシリンダとの間におけるストローク域を設定する必要がなくなり、コイルの励磁により推力を受ける可動子としてのマグネット管部を、フロント杆部と共に円筒マグネットがコイルの励磁を受けなくなった領域をも、シリンダ内部への通過移動が許容され、プランジャとして機能させることができ、コイルと共にマグネット管部の先端側をシリンダに近接し或いは内部に臨ませて配置することが可能となるばかりか、円筒マグネットを備えるマグネット管部を長尺に設定しても、その後端側に対し、シリンダの近接位置にまで及ぶコイルの励磁推力を与えながら移動することが可能となり、シリンダ内におけるピストンストローク域が長くなっても、マグネット管部の長さをコイルの励磁推力を受ける範囲に応じて可変するだけで長ストロークに対応することができ、しかも、コイルユニット管の外径をシリンダの筒径と略同径に設定するなど、リニア駆動機構の小型化や構造の簡略化、省スペース化が図られるだけでなく、両者が一本の筒状管体として一体化されたシリンダユニットとして構成することができ、もって、長ストロークを必要とする分注装置や、シリンダユニットを複数並設したシリンダブロックを備える分注装置に採用することができる。 The present invention is configured as described above, so that the piston is driven by a linear drive mechanism to suck and discharge the liquid into the nozzle tip or the like, but the stroke region between the magnet and the cylinder is It is no longer necessary to set the magnet tube as a mover that receives thrust due to coil excitation, and even the area where the cylindrical magnet is not subjected to coil excitation along with the front collar is allowed to move inside the cylinder. can function as a plunger, sets a distal end side of the magnet tube section together with the coil not only can be disposed in Mase extraordinary proximity to the cylinder or in the interior, a magnet tube portion comprising a cylindrical magnet in the longitudinal Even so, do not give the coil excitation thrust to the rear end of the coil up to the position close to the cylinder. Even if the piston stroke area in the cylinder becomes long, it is possible to cope with long strokes simply by changing the length of the magnet tube part according to the range that receives the excitation thrust of the coil. In addition to reducing the size of the linear drive mechanism, simplifying the structure, and saving space, such as setting the outer diameter of the coil unit tube to be approximately the same as the cylinder diameter of the cylinder, both have a single cylindrical shape. It can be configured as a cylinder unit integrated as a tubular body, and thus can be employed in a dispensing device that requires a long stroke and a dispensing device that includes a cylinder block in which a plurality of cylinder units are arranged in parallel.
このように構成することにより、リニア駆動機構によりプランジャ12をピストン駆動させて、液体をノズルチップ2内等に吸入し、吐出するものでありながら、円筒マグネット32とシリンダ11との間におけるストローク域を設定する必要がなくなり、コイル311の励磁により推力を受ける可動子としてのマグネット管部121を、フロント杆部122と共に円筒マグネット32がコイルの励磁を受けなくなった領域をも、シリンダ11内部への通過移動が許容されたプランジャ12として機能させることができ、コイル311と共にマグネット管部121(円筒マグネット32)の先端側をシリンダ11に近接し或いは内部に臨ませて配置することが可能となるばかりか、円筒マグネット32を備えるマグネット管部121を長尺に設定しても、その後端側に対し、シリンダの近接位置にまで及ぶコイル311の励磁推力を与えながら移動することが可能となり、シリンダ11内におけるピストンストローク域が長くなっても、マグネット管部121の長さをコイル311の励磁推力を受ける範囲に応じて可変するだけで長ストロークに対応することができる。 With this configuration, the plunger 12 is driven by the linear drive mechanism and the liquid is sucked and discharged into the nozzle tip 2 and the like, and the stroke region between the cylindrical magnet 32 and the cylinder 11 is discharged. The magnet tube portion 121 as a mover that receives thrust by the excitation of the coil 311 is not necessary, and the region where the cylindrical magnet 32 is not subjected to the excitation of the coil together with the front flange portion 122 is also connected to the inside of the cylinder 11. can function as a plunger 12 which passes through the mobile is allowed, together with the coil 311 to the distal end side of the magnet tube portion 121 (cylindrical magnet 32) only can be disposed in Mase extraordinary and or within close proximity to the cylinder 11 Or the magnet tube 121 having the cylindrical magnet 32 is elongated. Even if it is fixed, it is possible to move while applying the exciting thrust of the coil 311 extending to the proximity position of the cylinder with respect to the rear end side, and even if the piston stroke area in the cylinder 11 becomes long, the magnet tube portion 121 It is possible to cope with a long stroke only by varying the length of the length according to the range in which the excitation thrust of the coil 311 is received.
