Description

【0001】
【発明の属する技術分野】
本発明は主として、クリーム半田および厚膜回路形成用ペーストなどの印刷ペーストを、プリント基板などの電子回路形成基板に印刷を行うスクリーン印刷装置およびスクリーン印刷方法に関するものである。
【0002】
【従来の技術】
近年、スクリーン印刷装置において印刷品質向上、ファインピッチ化対応によりスクリーン版のクリーム半田やフラックスなどを拭き取る必要性が高まってきた。これを定期的あるいは適時に行う機能を有したスクリーン印刷装置が提供されている。
【0003】
以下、概略図面を参照しながら従来のスクリーン印刷装置を説明する。図3および図4は従来の機構を示したものである。
【0004】
1は巻き取り機構、2aは巻き取りホルダー、2bは巻き取り側押付けホルダー、4はパイプであり、パイプ4に加工された溝が3のピンにはまり込むようになっている。5a,5bはスキージ6を昇降させるシリンダーであり、ロール紙10はスキージ6により9のスクリーン版に押し当てられる。7は送り出し機構で11aの送り出しホルダーに直結される。11bは送り出し側押付けホルダーである。8はロール紙10の芯である。
【0005】
以上のように構成された従来クリーニング装置のスクリーン版を定期的あるいは適時に拭き取るスクリーン印刷方法についての動作を説明する。
【0006】
ロール紙10は、11aの送り出しホルダーと11bの送り出し側押付けホルダーにより保持され、7の送り出し機構によりバックテンションを与えられながら送り出される。ロール紙10はスキージ6により、スクリーン9に押しつけられながらスクリーン版に沿って移動する移動手段により、拭き取りを行う。この拭き取り動作が終了した後、印刷動作が再開される。
【0007】
使用済みのロール紙10は巻き取りホルダー2aと巻き取り側押付けホルダー2bに保持されたパイプ4に装着されていて、巻き取りホルダー2aに直結された巻き取り機構1により巻き上げられる。
【0008】
【発明が解決しようとする課題】
しかし、上記従来構成のスクリーン印刷装置は、ロール紙10を使い終えた場合は廃棄して新品と交換する様になっている為、ランニングコストにおいて課題を有していた。ランニングコスト低減の観点からロール紙の再利用、特に、未使用面である裏面の利用が考えられるが、上記従来のスクリーン印刷装置では、前記パイプ4からロール紙の芯8へ巻き直す必要があった為、作業性が悪いという問題と、また、ロール紙の裏面を使用するには、巻き取り方向が決まってしまう為に、巻き直し作業において作業ミスが起こりやすいという課題を有していた。
【0009】
本発明は、上記従来の問題点を解決するもので、ロール紙裏面の有効利用を容易にし、かつ、ロール紙の巻き直し作業を無くすことで、ランニングコストの軽減とロール紙交換時の作業性を良くする事ができるクリーニング装置を備えたスクリーン印刷装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
上記の問題を解決するために本発明のスクリーン印刷装置は、ロール紙を巻き取る為に軸心に沿ってスリットを有し、かつ、両端に位置決め用の切り欠きを複数個有するパイプと、前記パイプの先端を挿入し保持できる凹部を有し、かつ、前記パイプの位置決め用のピンを有し、かつ、巻き取り機構に直結される巻き取りホルダーと、前記パイプの先端を挿入し保持できる凹部を有し、かつ、前記パイプをスラスト方向に一定力で押しつけるスプリングを有する巻き取り側押付けホルダーと、前記ロール紙の芯の両端に挿入するテーパー部を有し、かつ、前記テーパーの逆側に前記パイプの外径に等しい凸部を有し、かつ、前記の凸部には位置決め用の複数個の切り欠きを有し、かつ、前記ロール紙のふらつきを押さえるつばを有するフランジと、前記フランジの凸部を挿入保持し、かつ、前記パイプの先端を保持可能な凹部を有し、かつ、前記フランジおよび前記パイプの位置決め用のピンを有し、かつ、送り出し機構に直結される送り出しホルダーと、前記フランジの凸部を挿入保持し、かつ前記パイプの先端を保持可能な凹部を有し、かつ、前記フランジおよび前記ホルダーをスラスト方向に一定力で押しつけるスプリングを有する送り出し側押付けホルダーを備え、前記巻き取りパイプの長さは、ロール紙の芯の両端へ前記フランジを挿入した長さに等しく構成され、前記巻き取りパイプは、前記送り出しホルダーへ、ロール紙は前記フランジを両端へ取り付けた状態で前記巻き取りホルダー側へ相互に取り付け可能としたことを特徴とするクリーニング装置を備えたものである。
【0011】
また、本発明のスクリーン印刷方法は、スクリーン版の拭き取りに使用されたロール紙の使用した面を内側になるように巻き取り手段に取り付けられたパイプへ巻き取り、前記ロール紙の片面を使い終えたら、前記パイプを巻き取り手段より、かつ、フランジをロール紙の芯へ挿入した状態で送り出し手段より取り外し、次に、使用済みロール紙を前記パイプに巻き取った状態で送り出し手段に取り付け、かつ、前記フランジとロール紙の芯へ挿入した状態で巻き取り手段に取り付けることにより、前記ロール紙の未使用面である裏面をスクリーン裏面に当接するよう相互を入れ替え、前記ロール紙の裏面を使用してスクリーン版の裏面を定期的あるいは適時に拭き取ることを特徴としたスクリーン印刷方法。
【0012】
上記スクリーン印刷装置および印刷方法によれば、巻き取り側と送り出し側の取り付け部分が同寸法になる為、相互に入れ替えが可能になり、使用済みの面を内側になるようパイプへ巻き取るので、巻き取り済みのパイプを送り出し側に装着した場合には、そのままロール紙の裏面を使用することができるので、ロール紙裏面の有効利用が容易になり、ランニングコストを軽減できるクリーニング装置を備えたスクリーン印刷装置を提供することが可能である。
【0013】
【発明の実施の形態】
(実施の形態1)
以下、本発明の実施の形態を図面に基づき説明する。なお従来と同機能のものには同符号を付す。
【0014】
図1および図2に示すように、ロール紙を巻き取る為に軸心に沿ってスリットを有し、かつ、両端に位置決め用の切り欠きを複数個有するパイプ4と、パイプ4の先端を挿入し保持できる凹部を有し、かつ、パイプ4の位置決め用のピン3を有し、かつ、巻き取り機構に直結される巻き取りホルダー2aと、パイプ4の先端を挿入し保持できる凹部を有し、かつ、パイプをスラスト方向に一定力で押しつけるスプリングを有する巻き取り側押付けホルダー2bと、ロール紙の芯8の両端に挿入するテーパー部を有し、かつ、テーパーの逆側にパイプ4の外径に等しい凸部を有し、かつ、凸部には位置決め用の複数個の切り欠きを有し、かつ、ロール紙10のふらつきを押さえるつばを有するフランジ13と、フランジ13の凸部を挿入保持し、かつ、パイプ4の先端を保持可能な凹部を有し、かつ、フランジ13およびパイプ4の位置決め用のピン3を有し、かつ、送り出し機構に直結される送り出しホルダー12aと、フランジ13の凸部を挿入保持し、かつパイプ4の先端を保持可能な凹部を有し、かつ、フランジ13およびロール紙の芯8をスラスト方向に一定力で押しつけるスプリングを有する送り出し側押付けホルダー12bを備え、パイプ4の長さは、ロール紙の芯8の両端へフランジ13を挿入した長さに等しく構成されている。
【0015】
これによって、巻き取りパイプ4は、送り出しホルダー12aと送り出し側押付けホルダー12bに、ロール紙10はフランジ13を取り付けて巻き取りホルダー2aと巻き取り側押付けホルダー2bへと相互に取り付け可能となっている。
【0016】
以上のように構成されたスクリーン印刷装置による印刷方法を図5(a)および図5(b)を用いて説明する。
【0017】
定期的あるいは適時にスクリーン版裏面の拭き取りに使用されたロール紙の使用した面を内側になるように巻き取り機構1と巻き取りホルダー2aと巻き取り側押付けホルダー2bより構成される巻き取り手段に取り付けられたパイプ4へ巻き取られる。この状態を図5(a)に示す。
【0018】
ロール紙の片面を使い終えたら、パイプ4を巻き取り手段より取り外し、またフランジ13とロール紙の芯8を送り出し機構7と送り出しホルダー12aと送り出し側押付けホルダー12bより構成される送り出し手段より取り外し、次に、使用済みロール紙をパイプ4に巻き取った状態で送り出し手段に取り付け、フランジ13とロール紙の芯8を巻き取り手段に取り付け、相互に入れ替えを行うことで次に裏面を使用して拭き取りを行う。この状態を図5(b)に示す。
【0019】
これによって、ロール紙10をパイプ4からロール紙の芯8へ巻き直しをする事なしに、ロール紙の両面を交互に使用することが可能となる。
【0020】
【発明の効果】
以上のように本発明によれば、巻き取り側と送り出し側の取り付け部分が共通化されるので相互に入れ替えが可能になり、使用済みの面を内側になるようパイプへ巻き取るので、使用済みロール紙の元の軸への巻き直しをする事なしにロール紙の表面と裏面を交互に使用できるので、ロール紙の裏面の有効利用とランニングコストの軽減ができるクリーニング装置を備えたスクリーン印刷装置を提供することが可能になる。

And a concave portion that inserts and holds the convex portion of the flange, and has a concave portion that can hold the tip of the pipe, and has a pin for positioning the flange and the pipe, and is directly connected to a feeding mechanism. A delivery holder having a recess for inserting and holding a protrusion of the flange and holding a tip of the pipe, and a spring for pressing the flange and the holder with a constant force in a thrust direction. A holder is provided, wherein the length of the take-up pipe is equal to the length of inserting the flange at both ends of the core of the roll paper, the take-up pipe is connected to the feed holder, and the roll paper is set at both ends of the flange. Equipped with a cleaning device characterized in that it can be mutually attached to the take-up holder side in a state where it is attached to A.
[0011]
Further, in the screen printing method of the present invention, the roll paper used for wiping the screen plate is wound around a pipe attached to a winding means so that the used surface is on the inside, and one side of the roll paper is used. Then, the pipe is removed from the feeding means with the winding means, and the flange inserted into the core of the roll paper, and then attached to the feeding means with the used roll paper wound on the pipe, and By attaching the flange and the roll paper to the take-up means in a state of being inserted into the core of the roll paper, the reverse side of the unused side of the roll paper is switched so as to abut against the screen rear side, and the back side of the roll paper is used. Screen printing method characterized in that the back side of the screen plate is periodically or timely wiped off.
[0012]
According to the screen printing apparatus and the printing method, since the mounting portions on the winding side and the sending side have the same dimensions, they can be interchanged with each other, and the used surface is wound on the pipe so that the used surface is on the inside. A screen equipped with a cleaning device that can use the back side of the roll paper as it is when the pipe that has been wound up is attached to the sending side, so that the back side of the roll paper can be used effectively and running costs can be reduced. It is possible to provide a printing device.
[0013]
