Description
【考案の詳細な説明】
本考案は印刷機のインキ出し装置に係をり、特にドクタ
ーブレードの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink dispenser for a printing press, and in particular to improvements to a doctor blade.
従来、インキ出し装置においてはドクターブレードと称
する薄板を調整ネジにより変形させて、インキ出しロー
ラとドクターブレードとの間隙を調整して所定量のイン
キを供給している。Conventionally, in an ink dispenser, a thin plate called a doctor blade is deformed by an adjustment screw to adjust the gap between the ink dispenser roller and the doctor blade to supply a predetermined amount of ink.
しかしこの方法はドクターブレードが薄板であるためド
クターブレードとインキ出しローラとの間隙がインキ出
しローラの周速の変化に起因してインキの膜圧力の変化
によりドクターブレードが変形して、第１図実線のよう
にドクターブレードとインキ出しロー２との間隙も変化
するのでインキ皮膜の厚さも一様にならず所望のインキ
量を供給することができない。However, in this method, since the doctor blade is a thin plate, the gap between the doctor blade and the ink dispenser roller is caused by changes in the circumferential speed of the ink dispenser roller, which causes the doctor blade to deform due to changes in the ink film pressure, as shown in Figure 1. As shown by the solid line, the gap between the doctor blade and the ink dispenser row 2 also changes, so the thickness of the ink film does not become uniform, making it impossible to supply the desired amount of ink.
本考案はかかる点にかんがみなされたもので、インキの
粘度やインキ出しローラの周速等の影響に係わりなく、
所望のインキ量を安定して供給できる印刷機のインキ出
し装置を提供するものである。The present invention was developed with this in mind, and regardless of the effects of ink viscosity, circumferential speed of the ink dispenser roller, etc.
An object of the present invention is to provide an ink dispenser for a printing press that can stably supply a desired amount of ink.
以下、本考案の詳細、を図面により説明する。The details of the present invention will be explained below with reference to the drawings.
第２図は本考案の実施例を示すインキ出し装置の概略構
造図で１はインキ出しローラ、２は図示しない印刷フレ
ームに固着した取付台づある。FIG. 2 is a schematic structural diagram of an ink dispenser showing an embodiment of the present invention, in which numeral 1 indicates an ink dispenser roller, and numeral 2 indicates a mounting base fixed to a printing frame (not shown).
３はインキ出しロー２１の軸長方向に複数個設けられた
剛体のカムレバーで、同カムレバー３の回転中心０３は

線上よりも上方の位置にあり、かつ着力点がカムレバー
３の回転中心０３よりも下方に位置する取付台２に螺着
した調整ネジ４にある。Reference numeral 3 designates a plurality of rigid cam levers provided in the axial direction of the ink fountain roller 21, and the rotation center 03 of the cam lever 3 is a surface that is close to or in contact with the rotation center o1 of the ink fountain roller 21 and the outer periphery of the ink fountain roller 1. Tsukamurapa 3
An adjustment screw 4 screwed into the mounting base 2 is located above the straight line connecting the arc centers 02 of the arc tip 6 attached to the cam lever 3, and the point of application is below the rotation center 03 of the cam lever 3. It is in.
５は引張バネで、その両端がカムレバー３と取付台２に
固着されていてカムレバー３と調整ネジ４の端が常時突
接するようになっている。Reference numeral 5 denotes a tension spring whose both ends are fixed to the cam lever 3 and the mounting base 2 so that the ends of the cam lever 3 and the adjustment screw 4 are always in abutting contact with each other.
本考案はこのような構成であるから円弧を有するチップ
６の円弧中心０２はカムレバー３の回転中心０３に対し
て偏心しており、調整ネジ４を図で左方に移動させると
カムレバー３は時計方向に回転してインキ出しローラ１
とカムレバー３との間隙が小さくなり、インキ出しロー
ラ１に供給されるインキ量が減ってくる。Since the present invention has such a configuration, the arc center 02 of the tip 6 having a circular arc is eccentric to the rotation center 03 of the cam lever 3, and when the adjusting screw 4 is moved to the left in the figure, the cam lever 3 moves clockwise. The ink dispenser roller 1 rotates to
The gap between the roller and the cam lever 3 becomes smaller, and the amount of ink supplied to the ink dispenser roller 1 decreases.
逆に調整ネジ４を図で右方に移動させるとカムレバー３
は引張バネ５の作用により反時計方向に回転するので、
インキ出しローラ１とカムレバー３との隙間は大きくな
ってインキ量が増す。Conversely, if you move the adjustment screw 4 to the right in the figure, the cam lever 3
rotates counterclockwise due to the action of the tension spring 5, so
The gap between the ink dispenser roller 1 and the cam lever 3 becomes larger, and the amount of ink increases.
なお第１図の一点鎖Ｍま本考案の実施例の結果を示す。The single-point chain M in FIG. 1 shows the results of an embodiment of the present invention.
以上説明したように本考案は従来のドクターブレードの
代りに剛体のカムレバーを設けたので、インキの粘度や
インキ出しローラの周速等の影響に係わりなく所望のイ
ンキ量を安定して供給できる。As explained above, in the present invention, a rigid cam lever is provided in place of the conventional doctor blade, so that a desired amount of ink can be stably supplied regardless of the effects of ink viscosity, circumferential speed of the ink dispenser roller, etc.
さらにインキ出しローラとカムレバーとの突接部分にお
いて、カムレバーに円弧のチップを取り付けであるので
接触部が磨滅したときにチップを交換するだけでよいの
で保守作業が簡単にできる。Furthermore, since an arcuate tip is attached to the cam lever at the abutting portion between the ink fountain roller and the cam lever, maintenance work can be simplified since it is only necessary to replace the tip when the contact portion becomes worn out.
