Description

【０００１】
【発明の属する技術分野】
本発明は、溶融樹脂の射出成形と同時にその表面に模様等を転写印刷する成形同時転写品の製造装置に関するものである。
【０００２】
【従来の技術】
射出成形品表面に、例えば模様を付する方法として、転写可能な模様印刷層を設けた転写フィルムをキャビティ内に送り、射出成形と同時に模様を成形品表面に転写するようにした、いわゆるインモールド転写が従来から知られている。このインモールド転写を実施する装置として、一般に以下のものが知られている。
【０００３】
図３に示す成形同時転写品の製造装置１は、昇降自在に支持された可動盤２と、可動盤２と相対して設けられた固定盤３と、可動盤２及び固定盤３の表面に設けられた金型３１、３２と、可動盤２の一方の側面に設けられ金型３１、３２同士の間に転写可能な印刷層を設けた転写フィルム６を供給する供給機構７と、可動盤２の他方の側面に設けられ成形品表面に転写された後の転写フィルム６を巻取る巻取り機構８と、金型３１、３２表面と転写フィルム６との距離及び平行度を調整する調整ローラ９とを備えている。
【０００４】
供給機構７と、巻取り機構８と、調整ローラ９とは、可動盤２側面に設けられた支持体１０に取付けられ、調整ローラ９は供給機構７から供給された転写フィルム６を金型３１、３２表面近傍に案内するとともに、転写フィルム６を引張状態にするように位置している。ここで、転写フィルム６は、図４に示すように、帯状の形状をなしており、その表面には幅方向に２つ並列して印刷層２１が形成され、転写フィルム６の長手方向（供給方向）には、これら印刷層２１が所定の間隔で断続的に形成されている。
【０００５】
また、金型３１、３２表面には、図４に示すように、印刷層２１の転写フィルム６の幅方向における形成位置と対応して、それぞれの金型３１、３２に相対する方向に開口したキャビティ形成部１１〜１４が、各金型３１、３２表面に並列に設けられている。
【０００６】
さらに、金型３２及び固定盤３の内部には、図３に示すように、キャビティ形成部１３、１４と連通しキャビティ形成部１１〜１４が形成するキャビティ内に溶融樹脂を供給する供給部１５が設けられている。また、金型３１及び可動盤２の内部には、キャビティ形成部１１、１２の底面部と連通し金型３１、３２同士の間に供給された転写フィルム６をキャビティ形成部１１、１２の底面部にそれぞれ吸着保持するバキューム流路１６が設けられている。
【０００７】
以上のように構成された成形同時転写品の製造装置１により、射出成形品を形成するとともに、形成された射出成形品表面に模様等を転写印刷する、いわゆる成形同時転写品の製造方法について説明する。
【０００８】
図３に示すように、まず、供給機構７により転写フィルム６を金型３１、３２同士の間に、転写可能な印刷層２１が設けられた面が金型３２と対向するように供給する。そして、可動盤２及び金型３１内部に設けられたバキューム流路１６にバキュームエアを供給し、転写フィルム６をキャビティ形成部１１、１２の底面部にそれぞれ吸着保持する。
【０００９】
この状態で、可動盤２を図示しない昇降手段により金型３１、３２の各表面同士が当接するまで上昇させる。これにより、キャビティ形成部１１、１３及び１２、１４がそれぞれ閉空間すなわちキャビティを形成し、このキャビティ内に供給部１５から溶融樹脂を供給し、射出成形品を形成する。この際、射出成形品の表面と転写フィルム６の印刷層２１が圧接し、この射出成形品の表面に転写印刷され、成形同時転写品が形成される。
【００１０】
【発明が解決しようとする課題】
ところで、上記従来の成形同時転写品の製造装置によれば、キャビティ形成部１１、１２底面部に転写フィルム６を吸着保持する際、転写フィルム６に延びが発生することから、上記各キャビティ内の平面視における印刷層２１の供給位置を予測することが困難であった。このため、キャビティ形成部１１〜１４の転写フィルム６表面に沿った配設位置に対して、印刷層２１の供給位置にずれが生じた場合には、転写フィルム６表面において印刷層２１の形成位置を変更した転写フィルム６を新たに製作する、あるいはキャビティ形成部の転写フィルム６表面に沿った配設位置を変更した金型３１，３２を新たに製作する必要が生ずる場合があり、上記位置調整をすることが困難であるという問題があった。
【００１１】
本発明は、このような事情を考慮してなされたもので、転写フィルム表面に形成された印刷層の供給位置に対するキャビティの配設位置を容易に調整することが可能な成形同時転写品の製造装置を提供することを目的とする。

【００１８】
【発明の実施の形態】
以下、図面を参照し、この発明の実施の形態について説明する。図３は、この発明の一実施形態として示した成形同時転写品の製造装置を示すものである。
図３に示す成形同時転写品の製造装置１は、昇降自在に支持された可動盤２と、可動盤２と相対して設けられた固定盤３と、可動盤２及び固定盤３の表面に設けられた金型４、５と、可動盤２の一方の側面に設けられ金型４、５同士の間に転写可能な印刷層を設けた転写フィルム６を供給する供給機構７と、可動盤２の他方の側面に設けられ成形品表面に転写された後の転写フィルム６を巻取る巻取り機構８と、金型４、５表面と転写フィルム６との距離及び平行度を調整する調整ローラ９とを備えている。
【００１９】
供給機構７と、巻取り機構８と、調整ローラ９とは、可動盤２側面に設けられた支持体１０に取付けられ、調整ローラ９は供給機構７から供給された転写フィルム６を金型４、５表面近傍に案内するとともに、転写フィルム６を引張状態にするように位置している。ここで、転写フィルム６は、図２に示すように、帯状の形状をなしており、その表面には幅方向に２つ並列して印刷層２１が形成され、転写フィルム６の長手方向（供給方向）には、これら印刷層２１が所定の間隔で断続的に形成されている。
【００２０】
また、金型４、５表面には、図２に示すように、それぞれの金型４、５に相対する方向に開口したキャビティ形成部１１〜１４が設けられ、これらキャビティ形成部１１〜１４は、上記並列して形成された印刷層２１の転写フィルム６の幅方向に対する形成位置と対応するように、各金型４、５表面に並列して設けられている。すなわち、金型４表面には、キャビティ形成部１１、１２が、転写フィルム６の幅方向に対して並列に設けられ、金型５表面には、キャビティ形成部１３、１４が、同様にして並列に設けられた構成となっている。
【００２１】
さらに、金型５及び固定盤３の内部には、図３に示すように、キャビティ形成部１３、１４と連通しキャビティ形成部１１〜１４が形成するキャビティ内に溶融樹脂を供給する供給部１５が設けられている。また、金型４及び可動盤２の内部には、キャビティ形成部１１、１２の底面部と連通し金型４、５同士の間に供給された転写フィルム６をキャビティ形成部１１、１２の底面部にそれぞれ吸着保持するバキューム流路１６が設けられている。
以上の構成は上述した構成と同様である。
【００２２】
ここで、金型４は、図１に示すように、可動盤２表面において、キャビティ形成部１１、１２を各別に備えた本体部２２、２３と、各本体部２２、２３同士の間に設けられ各本体部２２、２３の一方の側面と当接する交換可能なスペーサ２６と、各本体部２２、２３の他方の側面をスペーサ２６側へ各別に押圧する押圧機構部２８とを備えている。スペーサ２６は、転写フィルム６の幅方向の中央部に設けられ、各本体部２２、２３と押圧機構部２８とは、スペーサ２６を挟んで転写フィルム６の幅方向に順次並列して設けられた構成となっている。
【００２３】
金型５は、固定盤３表面において、金型４と同様にして、キャビティ形成部１３、１４を各別に備えた本体部２４、２５と、各本体部２４、２５同士の間に設けられ各本体部２４、２５の一方の側面と当接する交換可能なスペーサ２７と、各本体部２４、２５の他方の側面をスペーサ２７側へ各別に押圧する押圧機構部２８とを備えている。スペーサ２７は、転写フィルム６の幅方向の中央部に設けられ、各本体部２４、２５と押圧機構部２８とは、スペーサ２７を挟んで転写フィルム６の幅方向に順次並列して設けられた構成となっている。
【００２４】
この構成において、可動盤２が上昇し、金型４、５の各表面同士が当接した際、キャビティ形成部１１、１３及び１２、１４がそれぞれキャビティを形成する構成となっている。また、本体部２２〜２５の上記一方の側面には、該面と、可動盤２又は固定盤３表面との交差部に凸部４１が設けられ、各スペーサ２６、２７の、各本体部２２〜２５の上記一方の側面との当接面には、該面と、金型４、５の各表面との交差部に凸部４２が設けられている。
【００２５】
ここで、スペーサ２６、２７の表面において、転写フィルム６の幅方向中央部には、ザグリ孔及び該ザグリ穴と同軸且つ小径の貫通孔が形成され、該貫通孔にボルト３４が嵌挿され、ボルト３４は可動盤２及び固定盤３表面に形成された図示しない雌ネジと螺着した構成となっている。すなわち、このボルト３４をねじ込むことにより、スペーサ２６、２７に形成された凸部４２が、本体部２２〜２５に形成された凸部４１を押圧する構成となっている。
【００２６】
各本体部２２〜２５の上記他方の側面は、本体部２２〜２５の上端面（金型４、５の各表面）から下端面（可動盤２、固定盤３の表面）に向かうに従い漸次、転写フィルム６の幅方向に対して拡幅する傾斜形状に形成されている。この各本体部２２〜２５の上記他方の側面の近傍には、上述したように、各本体部２２〜２５を各別にスペーサ２６、２７側に押圧する押圧機構部２８が設けられている。押圧機構部２８は、可動盤２、固定盤３表面に立設されたスライド部２９と、各本体部２２〜２５の上記他方の側面と当接し、これら本体部２２〜２５を各別にスペーサ２６、２７側に押圧するくさび部材３０とを備えている。
【００２７】
スライド部２９には、その上端面から下端面（可動盤２、固定盤３の表面）にかけて溝部３１が形成され、この溝部３１に、くさび部材３０の一方の端面部が嵌合した構成となっている。また、くさび部材３０の他方の端面部は、各本体部２２〜２５の上記他方の側面に形成された傾斜形状の傾斜角と略同角度とされた傾斜形状とされ、この傾斜面が、本体部２２〜２５の上記他方の側面と当接した構成となっている。
【００２８】
また、くさび部材３０の表面において、各本体部２２〜２５とこれらに対応して設けられた各スライド部２９との間の中央部には、貫通孔が設けられている。この貫通孔にはボルト３３が嵌挿され、このボルト３３は、可動盤２及び固定盤３表面に各別に形成された雌ネジと螺着した構成をなしている。すなわち、ボルト３３をねじ込むことにより、くさび部材３０は可動盤２又は固定盤３の表面に近接する方向に移動するとともに、本体部２２〜２５の上記他方の側面及びくさび部材３０の上記他方の端面部に形成された傾斜面の傾斜角に依存して、各本体部２２〜２５がスペーサ２６、２７側へ各別に押圧される構成となっている。
【００２９】
以上のように構成された成形同時転写品の製造装置１により、射出成形品を形成するとともに、形成された成形品表面に模様等を転写印刷する、いわゆる成形同時転写品の製造方法について説明する。
【００３０】
まず、供給機構７により転写フィルム６を金型４，５同士の間に供給する。この際、転写フィルム６は、転写可能な印刷層２１が設けられた面が金型５と対向するように供給されるとともに、金型４、５表面に形成されたキャビティ形成部１１〜１４の平面視において印刷層２１が所定の位置に供給されている。そして、可動盤２及び金型４内部に設けられたバキューム流路１６にバキュームエアを供給し、転写フィルム６をキャビティ形成部１１、１２の底面部に吸着保持する。この状態で、可動盤２を図示しない駆動手段により金型４、５の各表面同士が当接するまで上昇させる。これによりキャビティ形成部１１、１３及び１２、１４がそれぞれ閉空間、すなわちキャビティを形成し、このキャビティ内に供給部１５から溶融樹脂を射出供給し、射出成形品を形成する。この際、射出成形品の表面と転写フィルム６の印刷層２１が圧接し、この射出成形品の表面に転写印刷され、成形同時転写品が形成される。
【００３１】
次に、キャビティ形成部１１〜１４の転写フィルム６表面に沿った位置調整方法、すなわち転写フィルム６表面に形成された印刷層２１をキャビティ形成部１１〜１４の平面視において所定の位置に配置させる方法について説明する。
【００３２】
予め、図１に示すように、転写フィルム６の幅方向に対して様々な幅寸法Ａ、Ｂで形成されたスペーサ２６、２７を複数形成しておく。この幅寸法Ａ、Ｂの差分は、上記複数のスペーサ２６、２７において全て同一にしておく。そして、まず、供給される転写フィルム６表面に形成された各印刷層２１の、転写フィルム６の幅方向の距離及びキャビティ形成部１１、１２の底面部に吸着保持する際に、転写フィルム６に生じる延び等を考慮して所定の幅寸法Ａ、Ｂで形成されたスペーサ２６、２７を可動盤２及び固定盤３表面にそれぞれ保持する。
【００３３】
そして、本体部２２、２３を、これら本体部２２、２３の上記一方の側面と、スペーサ２６とが当接し、且つスペーサ２６を介して転写フィルム６の幅方向に並列するように載置する。本体部２４、２５についても、同様にして、スペーサ２７と当接し且つ並列するように載置する。その後、くさび部材３０の上記一方の端面部をスライド部２９の溝部３１に嵌合するとともに、ボルト３３をねじ込み、くさび部材３０を可動盤２又は固定盤３の表面に近接する方向に移動させる。この際、くさび部材３０の上記他方の端面部に形成された傾斜面により、本体部２２〜２５の上記他方の側面に形成された傾斜面を押圧し、各本体部２２〜２５がそれぞれスペーサ２６、２７側に押圧される。そして、ボルト３４をねじ込むことにより、スペーサ２６、２７の凸部４２が、本体部２２〜２５の凸部４１を押圧することにより、スペーサ２６及び本体部２２、２３と、スペーサ２７及び本体部２４、２５とがそれぞれ強固に可動盤２、固定盤３表面に保持される。
【００３４】
この状態で、上述したように、成形同時転写品を形成し、射出成形品表面の所望の位置に転写印刷されているか否かを確認し、その位置にずれが生じていた場合には、別の幅寸法Ａ、Ｂを備えたスペーサ２６、２７を再取付けし、上述した方法と同様にして、上記位置調整を行う。
【００３５】
以上説明したように、本実施形態による成形同時転写品の製造装置によれば、転写フィルム６表面に形成された印刷層２１の供給位置をキャビティ形成部１１〜１４の平面視において、所定の位置に配置させる調整を行うに際し、予め、幅寸法Ａ、Ｂの異なる複数のスペーサ２６、２７を形成しておき、これらのうちから選択して取付け交換することによりなす構成となっている。従って、容易且つ確実に上記位置調整を実施することが可能になる。
【００３６】
【発明の効果】
以上の説明から明らかなように、請求項１に係る発明によれば、上記印刷層の供給位置を上記キャビティ形成部の平面視において、所定の位置に配置させる調整を容易になすことが可能になる。
【００３７】
請求項２に係る発明によれば、上記印刷層の供給位置を上記キャビティ形成部の平面視において、所定の位置に配置させる調整を容易且つ確実になすことが可能になる。
【００３８】
