Abstract

PURPOSE:To perform the supply of a highly precise ink to be blended automatically at a high accuracy by a method wherein, at first, ink is discharged continuously from a rough discharge valve of a large calibre and then, intermittently from a fine discharge valve as the measured value approaches the set value. CONSTITUTION:An ink 2 in an ink storage tank 1 is fed to a rough discharge valve 5 and a fine discharge valve 6 with a pressure feed pump 3. The weight of the ink is measured with a digital mesuring gauge 8 and inputted into an arithmetic means 9 as ink discharge value signal (g). The set measured value memorized in a set measured value memory means 10 is also inputted thereinto 9 to be computed in comparison with an ink discharge value and any of a rough discharge signal, a fine discharge signal and an end signal is generated selectively. When the rough discharge signal is selected, a valve control means 7 opens the rough discharge valve 5 while closing the fine discharge valve 6. When the fine discharge signal is selected, the fine discharge valve 6 is opened or closed intermittently while the rough discharge valve 5 is closed. Further, when the end signal is selected, both the valves 5 and 6 are closed.

Description

【発明の詳細な説明】 従来より、数種類の印刷インキを混ぜ合せて特殊な色の
インキを調合し、該インキを用いて印刷を行なうことは
良く知られている。−このように調合されたインキは特
色インキと一般的にこの特色インキが多く採用されてい
る。DETAILED DESCRIPTION OF THE INVENTION It has been well known to mix several types of printing inks to formulate a special color ink, and to perform printing using this ink. -The ink prepared in this way is a special color ink, and this special color ink is generally used in many cases.

このような特色イｙｄｔの調合を行なうに当っては混ぜ
合わせる各々のインキを正確に秤量することか必要とな
る。In preparing such a special color ydt, it is necessary to accurately weigh each ink to be mixed.

すなわち、混ぜ合わせるインキの量が正確でない場合に
は、必要とされる色が得られず、従ってその分のインキ
は全て使用不可となってしまい、調合したインキが無駄
になってしまう。That is, if the amount of ink to be mixed is not accurate, the required color will not be obtained, and therefore all of the ink will become unusable, and the mixed ink will be wasted.

例えば５００ｇの特色インキを３色のインキを用いて作
成する場合に、赤インキを７２．２７　ｇ青インキを１
２８．２９ｇ、紫インキを１３７．９７ｇ希釈インキを
１６１．４７　ｇ混合させる必要があるとすれば、それ
ぞれのインキの精度は±１０ｍｇ程度を必要とされる。For example, when creating 500 g of special color ink using three color inks, 72.27 g of red ink and 1 g of blue ink are used.
If it is necessary to mix 28.29 g of purple ink, 137.97 g of purple ink, and 161.47 g of diluted ink, the accuracy of each ink is required to be about ±10 mg.

従来このようなインキ調合のためのインキの秤量は人間
がデジタル秤量計を用いて行なっており、非常に手間と
時間のかかる作業となっている。Conventionally, weighing of ink for such ink mixing has been carried out by humans using digital weighing scales, which is a very labor-intensive and time-consuming task.

更に、特にオフセット印刷用のインキは粘度が４００〜
８００　ポイズ程度のものであり、かなり高粘度である
ため、精度を上げるために少量ずつ秤量計上に滴下させ
るに当って空気中に滞溜しているインキ滴の量が問題と
なる。すなわち空気中に滞溜しているインキ滴が大きす
ぎるとインキ量が多くなり過ぎてしまう。Furthermore, ink especially for offset printing has a viscosity of 400~
Since it has a fairly high viscosity of about 800 poise, the amount of ink droplets that accumulate in the air poses a problem when dropping small amounts onto a weighing scale in order to improve accuracy. That is, if the ink droplets accumulated in the air are too large, the amount of ink will become too large.

本発明の目的は以上の如き従来の問題点を解消させ、調
合すべきインキの供給を精度よく、しかも人手によらず
に自動的に行なわしめることを目的とする。It is an object of the present invention to solve the above-mentioned conventional problems and to supply ink to be mixed accurately and automatically without manual intervention.

更に本発明の他の目的は上記供給は粘度の高いインキに
おいても適用可能とすると共に、粘度の高いインキであ
っても能率的に供給可能とすることにある′。Still another object of the present invention is to make the above-mentioned supply applicable even to highly viscous ink, and to make it possible to efficiently supply even highly viscous ink.

本発明によれば上記目的を達成するインキ供給装置が提
供される。According to the present invention, an ink supply device that achieves the above object is provided.

3) The power source for opening and closing the pulp valves of the two types of ink discharging pulp utilizes 5 to 6-/- pressurized air. Such pressurized air is fed through an air pipe (12). Such pressurized air is commonly used in printing factories, and it is often convenient for air pipes to be installed as branch pipes instead of those already installed in the factory.

One with an inner diameter of 0.7 mm can be mentioned.

こうした場合には荒吐出パルプからは１００〜２００ｍ

It is possible to eject ink at a rate of approximately g/sec (continuous ejection).

も達成される。In the micro discharge valve, ink is discharged intermittently, and 4 to 5 meters are discharged at one time.In this case, offset ink has a high viscosity, and the ink that is discharged intermittently becomes a thin string. It stays near the outlet for a while and then falls under its own weight. Therefore, in the case of continuous dispensing, the ink floating in the air when the ink falling on the weighing scale reaches the set value is a major cause of error, but in the case of the small amount discharging pulp of the device of the present invention, Since the ink is divided into about 4 to 5 mg and intermittently discharged, the ink floating in the air falls and the ink increase is weighed before the ink discharge is controlled. An increase in accuracy is therefore also achieved.

The required amount of ink can be quickly and accurately supplied automatically with a preset amount of ink.
