【発明の属する技術分野】
本発明は、単一の前後進シリンダの前進により、複数種の液状材料を同時に押し出す液状材料射出装置に関する。
【0002】
【従来技術】
従来、この種の装置として図3に示す構造が一般に知られている。
【0003】
図3の構造をもって従来技術について説明すると、単一の前後進シリンダ100におけるピストン101の前端に、液状材料用射出シリンダ200,300,400を複数個備え、上記ピストン101の前進作動に伴って夫々の射出シリンダ200,300,400のピストン201,301,401が同時に前進作動を行い、夫々のシリンダ200,300,400内に送り込まれている複数種類の液状材料を同時に押し出す構造である。
【0004】
また、図面では、各射出シリンダ200,300,400の容量が同一のものをもって説明するが、一部のシリンダ(例えばシリンダ400)のみを小容量とするものも同様に知られている。尚、図中500,600,700は、夫々液状材料タンクを示す。
【0005】
【発明が解決しようとする課題】
しかし、上述の従来構造では、夫々の液状材料の押し出し量の比率が決まっており、任意の一つ若しくは複数の液状材料の押し出し量を、液状材料の所要混合比率に応じてその都度任意に変えることはできなかった。
【0006】
すなわち、現在提供されている装置では、複数種類の液状材料を一定の混合比率でしか得られず、例えばシリンダ200,300の液状材料の押し出し量に比して少量の液状材料をシリンダ400から押し出すことは、該シリンダ400を小容量のものと形成してあれば可能であるが、このシリンダ400の押し出し量を適宜必要に応じて変更することはできなかったものである。
【0007】
また、必要に応じて夫々容量の異なった射出シリンダを部分的に取り替える構造とすることも考えられるが、押し出し量に応じた容量の射出シリンダを多数用意する必要があった。これでは、コストが嵩むばかりでなく、交換作業上、管理上においても大変煩わしく面倒であった。
【0008】
本発明は、従来技術の有するこのような問題点に鑑みなされたものであり、その目的とするところは、単一の前後進シリンダによる前進動作で複数の液状材料を同時に押し出す装置において、液状材料の押し出し量の所要混合比率に応じてその都度液状材料の押し出し量を増減変更可能な液状材料射出装置を提供することである。

【0010】
また、複数の液状材料用射出シリンダを備えると共に、夫々の射出シリンダのピストンを単一の前後進シリンダの前進により同時に前進せしめて、複数種の液状材料を同時に押し出す装置であって、前記複数個の液状材料用射出シリンダにおける任意の一個若しくは複数個のピストンの前後進移動量を任意に調整する調整部材を一個若しくは複数個備え、該調整部材は、前記前後進シリンダと共に連動せしめて前後進可能に構成されると共に、射出シリンダにおけるピストンの一端を摺接せしめて該ピストンを前後進せしめ、前記複数の液状材料用射出シリンダは、前後進シリンダの前進により該前後進シリンダと同一方向に前進作動するピストンを備えた射出シリンダと、前後進シリンダの前進作動と共に前進する調整部材により前後進シリンダの前進方向と直交する方向に前進作動するピストンを備えた射出シリンダであることを特徴とする液状材料射出装置とする場合もある。

【0014】
前後進シリンダ2は、ピストン2aの先端にプレート2bを一体的に取り付け、該プレート2bの前面2cに第一液状材料用射出シリンダ3,第二液状材料用射出シリンダ4の夫々のピストン3a,4aの一端側を固定し、上面2dには調整部材6を一体的に取り付けている。
【0015】
液状材料用射出シリンダは、前後進シリンダ2の前進方向と同一方向(図1中矢印Y方向)に前進作動するピストン3a,4aを備えた並列する第一液状材料用射出シリンダ3,第二液状材料用射出シリンダ4と、前後進シリンダ2のプレート上面2dに取付けられ、該前後進シリンダ2の前進作動と共に前進する調整部材6により前後進シリンダ2の前進方向と直交する方向(図1中矢印X方向)に前進作動するピストン5aを備えた第三液状材料用射出シリンダ(押し出し量調整可能なシリンダ)5である。
【0016】
上記第三液状材料用射出シリンダ5は、例えば本実施形態では、第一,第二液状材料用射出シリンダ3,4と直交するように上方位置に備えられ、ピストン5aの下端5bを調整部材6の傾斜角度調整可能な押上げ作動部6bの表面6eに摺接せしめている。
【0017】
本実施形態における第三液状材料用射出シリンダ5は、ピストン5aの下端5bにローラ5cを回転自在に備えて調整部材6とのスムーズな摺動を得る構造としている。なお、このローラ5cは特に限定される構造ではなく、調整部材6の移動に応じてピストン5aのスムーズな前後進作動が得られるものであれば限定はされず、他の構造を備えるもの、あるいは備えないものとすることなど選択可能である。
【0018】
また、本実施形態における第三液状材料用射出シリンダ5は、第一,第二射出シリンダ3,4と比して小容量状に形成しているが、特にその容量は限定されず、第一,第二射出シリンダ3,4と比して同容量、あるいは大容量とするも自由である。
【0019】
また、上記第一,第二液状材料用射出シリンダ3,4は、特にその構造、例えば容量、形状など任意にその構造が選択可能である。さらに、第一,第二,第三液状材料用射出シリンダ3,4,5は、任意に配設数が選択可能で、複数個配設し、任意の一つあるいは全てがピストンの移動距離調整が可能とするものであれば本発明の範囲内である。
【0020】
調整部材6は、第三液状材料用射出シリンダ5におけるピストン5aの前後進移動量を任意に調整するものであり、例えば次のような構成が実施の一形態として挙げられる。
【0021】
図1,2に示す実施形態における調整部材6は、前後進シリンダ2に取付けられたプレート2bと直交状に取付けられる取付プレート6aと、該取付プレート6aに前端6c側を回動可能に軸着すると共に、取付けプレート6aから立設された角度調整機構6fの一端6gを後端6d側に取付けて上下方向に傾斜角度調整可能とされた押上げ作動部(押上げ作動プレート)6bとから構成されており、該押上げ作動プレート6bの表面6eに第三液状材料用射出シリンダ5におけるピストン5aの下端5bが摺接している。

【0024】
まず、第一液状材料用射出シリンダ3,第二液状材料用射出シリンダ4,第三液状材料用射出シリンダ5に、夫々異なった所望な液状材料(例えばA液、B液、C液)を夫々送り込む。そして、前後進シリンダ2を前進作動せしめると、該シリンダ2のピストン2aの前進により第一液状材料用射出シリンダ3,第二液状材料用射出シリンダ4のピストン3a,4aが同時に前進作動を行い、A液・B液を押し出す。この時、前記前後進シリンダ2の前進作動と共に、該シリンダ2に一体的に備えられた調整部材6も同時に前進作動を開始し、該調整部材6の押上げ作動プレート6bの表面傾斜に従って第三液状材料用射出シリンダ5のピストン5aが前進作動を行い、C液も同時に押し出される。すなわち、このC液の押し出し量は、調整部材6の押上げ作動ブレート6bの傾斜角度の緩急調整によってピストン5aの移動距離が長短調整されるため増減変更可能である。
【0025】
本実施形態における第一,第二,第三液状材料用射出シリンダ3,4,5から押し出されるA液、B液、C液の夫々の比率一例を、調整部材6の押上げ作動プレート6bの傾斜角度を数例挙げて説明すると、次のように例示される。尚、下記例は一例であってこれに何等限定されるものではない。

Figure 0004385352
【0026】
上述した本実施形態では、第三液状材料用射出シリンダ5のみに調整部材6を用いてピストン5aの移動量調整を行い、該第三液状材料用射出シリンダ5からの液状材料の押し出し量のみを必要に応じて増減変更調整可能とするが、第一,第二液状材料用射出シリンダ3,4にも前記同様に別途前後進シリンダ2と連動する調整部材6を備えることで、他のシリンダ3,4における液状材料の押し出し量調整ができる構造とすることも本発明の範囲内である。
例えば、本実施形態に示す調整部材6と同一構成の調整部材を、同様にプレート2bに一個乃至複数個取付けると共に、夫々の押上げ作動プレート6b表面にピストン3a,4aの一端を摺接せしめて必要数の液状材料用射出シリンダ3,4を備える構造とする。
【0027】
【発明の効果】
本発明は、上述の通りの構成であることから、単一の前後進シリンダによる前進動作で複数の液状材料を同時に押し出す装置において、液状材料の押し出し量の所要混合比率に応じてその都度液状材料の押し出し量を増減変更可能な液状材料射出装置が提供できた。すなわち、調整部材の傾斜角度を適宜緩急調整することで、前記射出シリンダのピストンの移動距離を長短調整し、射出シリンダからの液状材料の押し出し量が増減調整可能となる。
