【発明の詳細な説明】
本発明は印刷器用のインク濃度管理方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for managing ink density for a printer.
印刷に使用するインクの濃度は印刷の良否の大
きな要因であるが、従来インクの濃度管理は作業
者の勘にたよつたり、粘度計により粘度の測定を
しながら溶剤を供給していた。 The concentration of the ink used for printing is a major factor in the quality of printing, but conventionally, ink concentration management has relied on the intuition of operators, or the solvent has been supplied while measuring the viscosity with a viscometer.
その為適正な濃度にする事が困難で、また長時
間作業の場合溶剤の蒸発により濃度が変化し、そ
の都合溶剤を補充しなければならず、多くの手間
を要する欠点があつた。 Therefore, it is difficult to obtain an appropriate concentration, and when working for a long time, the concentration changes due to evaporation of the solvent, which requires replenishment of the solvent, which has the disadvantage of requiring a lot of effort.
本発明は前記した従来技術の欠点を解消し、常

る事にある。 The present invention aims to solve the above-mentioned drawbacks of the prior art, provide a management method for always maintaining an appropriate ink density, and achieve stable printing operations. In other words, the gist of the present invention is to rotate a disk (blade) to detect the ink concentration as a change in viscosity, detect a change in the torque that drives it as a change in the current of the drive motor, and control it using the signal. The purpose is to automatically change the opening/closing amount of the valve and automatically adjust the supply (replenishment) of the solvent to keep the concentration constant at all times.

構成される装置にて行う。 Next, an embodiment of the method of the present invention will be further described with reference to the accompanying drawings. It consists of a disk (blade) 5 that rotates with a motor, a motor 6 that drives the disk, a controller 7 that detects the motor current and controls the opening/closing amount of the control valve, and a control valve 8 that controls the amount of solvent supplied. Performed using equipment.

溶剤３がインクタンク２内に適量供給され、常に
一定の濃度のインクとする事が出来る。 Disc 5 driven by motor 6 within ink 1
produces a load due to the viscous resistance of the ink. When the ink concentration changes, the viscous resistance also changes, so the load on the drive motor 6 also changes. Therefore, if the control valve 8 is opened or closed based on the change in the current of the motor 6 at that time using a signal passed through the controller 7,
An appropriate amount of the solvent 3 is supplied into the ink tank 2, and the ink can always have a constant concentration.
本実施例に於ては、濃度の変化を電流値で検出
したが、直接トルクを測定する方法でも可能であ
るし、又トルクモーターのようにトルク変化によ
り回転数が変化するモーターを使用すれば、回転
数で検出する事も可能である。 In this example, the change in concentration was detected by the current value, but it is also possible to directly measure the torque, or if a motor such as a torque motor whose rotational speed changes depending on the torque change is used. It is also possible to detect the rotation speed.
また溶剤の供給は、コントロールバルブの開閉
量を調整しなくても開閉だけのON，OFF制御で
も可能である。 In addition, the solvent can be supplied by ON/OFF control of only opening and closing without adjusting the opening/closing amount of the control valve.
本発明は印刷作業の安定化を目的としている
が、インク以外に溶剤を使用する液体の濃度管理
にも使用可能である。 Although the present invention is aimed at stabilizing printing operations, it can also be used to manage the concentration of liquids other than ink that use solvents.
以上説明した通り、本発明インク濃度の管理方
法によれば、正確な濃度のインクを安定して保持
出来ると共に、長時間経ても常に一定の濃度のイ
ンクを保持出来る利点がある。 As explained above, the ink density management method of the present invention has the advantage that it is possible to stably maintain ink at an accurate density, and it is also possible to always maintain ink at a constant density even after a long period of time.

刷作業が可能となるものであり、その工業的価値
は大なるものがある。 Furthermore, the rotating disk (blade) produces a stirring effect, which has the advantage of making the ink in the tank uniform. Therefore, by making the ink concentration uniform, stable printing operations are possible, and its industrial value is great.
