Description
本發明係關於一種使用水性油墨的凹版印刷機中的水性油墨的調溫裝置。The present invention relates to a temperature regulating device for an aqueous ink in an intaglio printing machine using an aqueous ink.
在凹版印刷方面，與使用油性油墨相比，使用水性油墨在環境對策方面以及印刷作業環境方面極為有效，因此，本案申請人提出了日本特願平11-211532號、日本特願平11-250423號、日本特願平2000-141712號、日本特願平2000-106154號等符合實際使用之發明。In terms of gravure printing, the use of water-based inks is extremely effective in terms of environmental countermeasures and printing work environment compared with the use of oil-based inks. Therefore, the applicant of the present application has proposed Japanese Patent No. 11-211532 and Japanese Tetsu-Ping 11-250423. No., Japan's special wish 2000-141712, Japan's special wish 2000-106154 and other inventions that are in practical use.
另外，由於水性油墨的情況時所使用的油墨溫度對印刷的最終結果會產生重大影響，因此本案申請人提出了油墨溫度調為15℃~28℃進行印刷的方案(日本特開2002-086886號)。In addition, since the ink temperature used in the case of the aqueous ink has a significant influence on the final result of printing, the applicant of the present application proposed a printing method in which the ink temperature is adjusted to 15 ° C to 28 ° C (Japanese Patent Laid-Open No. 2002-086886). ).
亦即，由於夏季和冬季的氣溫變化，會造成水性油墨的溫度大幅變動。例如，水性油墨的溫度降到15℃以下時，水性油墨的黏度會上升而使潤濕不足，產生漏印、濃淡不均，當溫度為28℃以上時，則黏度會降低，從版筒掉下的水性油墨會在油墨池內產生泡沫，由於產生泡沫而會使空氣混入至水性油墨內。而且，水性油墨內混入有空氣時，會使版筒潤濕狀況不良，此時會在印刷中出現漏印、濃淡不均，成為印刷不良的起因。That is, the temperature of the aqueous ink changes drastically due to temperature changes in summer and winter. For example, when the temperature of the aqueous ink drops below 15 ° C, the viscosity of the aqueous ink will increase and the wetting will be insufficient, resulting in uneven printing and unevenness. When the temperature is above 28 ° C, the viscosity will decrease and the product will fall from the plate. The lower aqueous ink will create a foam in the ink pool, which will cause air to mix into the aqueous ink due to the foam. Further, when air is mixed in the water-based ink, the wetness of the plate is poor, and at this time, printing and unevenness may occur during printing, which may cause printing defects.
專利文獻1：日本特開2002-086886號公報。Patent Document 1: Japanese Laid-Open Patent Publication No. 2002-086886.
作為解決上述印刷不良問題的手段，上述專利文獻1中，直接在油墨池的底部安裝熱交換器，使熱源機產生的熱媒在上述熱交換器內循環，對油墨池內的水性油墨進行溫度調節。但是，在上述調溫機構的情況存在以下問題。As a means for solving the above-described problem of printing failure, in Patent Document 1, a heat exchanger is directly attached to the bottom of the ink pool, and the heat medium generated by the heat source machine is circulated in the heat exchanger to perform temperature on the aqueous ink in the ink pool. Adjustment. However, in the case of the above temperature control mechanism, there are the following problems.
1.由於油墨池內的水性油墨的量通常為3~6L，所以，即使用安裝在油墨池底部的熱交換器對上述油墨池內的水性油墨進行調溫，也會在油墨池內的水性油墨表面側和熱交換器相接的油墨池底部側產生水性油墨溫度不均勻，無法藉由穩定的調溫進行加工質量良好的印刷。1. Since the amount of aqueous ink in the ink pool is usually 3~6L, the water-based ink in the ink pool is tempered by using a heat exchanger installed at the bottom of the ink pool, and the water is also in the ink pool. The ink ink surface side and the bottom side of the ink tank that is in contact with the heat exchanger cause uneven temperature of the aqueous ink, and it is impossible to perform processing with good processing quality by stable temperature adjustment.
2.由於在油墨池底部安裝著熱交換器，所以，固定物會沉澱附著在油墨池的內底部，因此必須進行頻繁的清掃。2. Since the heat exchanger is installed at the bottom of the ink pool, the fixture adheres to the inner bottom of the ink pool, so frequent cleaning is necessary.
3.在使冷煤在熱交換器內進行循環來將水性油墨冷卻的情況時，油墨池內，下層的水性油墨會被冷卻，而浸潤版筒的上層水性油墨則需要時間來被冷卻，而在作業開始的時候需要等待的時間。3. When the cold coal is circulated in the heat exchanger to cool the aqueous ink, the aqueous ink in the lower layer of the ink pool is cooled, and the upper aqueous ink of the infiltrated cylinder takes time to be cooled. The amount of time to wait at the start of the job.
4.由於在油墨池的底部進行調溫，因此，為了使油墨池內的油墨溫度均勻化，必須另行安裝用來攪拌水性油墨的裝置。當然，當版筒開始旋轉時水性油墨即受到攪拌，但是該攪拌現象出現在油墨池的上層部，而不是整體的攪拌，因此幾乎不能實現油墨溫度的均勻化。4. Since the temperature is adjusted at the bottom of the ink pool, in order to make the temperature of the ink in the ink pool uniform, a device for stirring the aqueous ink must be separately installed. Of course, the aqueous ink is agitated when the plate starts to rotate, but the agitation phenomenon occurs in the upper portion of the ink pool, rather than the overall agitation, so that the uniformity of the ink temperature can hardly be achieved.
本發明鑑於上述問題而提出，其第一目的是提供一種凹版印刷機中的油墨調溫裝置，其可以對油墨池內的油墨溫度均勻地進行調溫，進行加工質量良好的印刷。The present invention has been made in view of the above problems, and a first object thereof is to provide an ink temperature regulating device in a gravure printing machine which can uniformly adjust the temperature of an ink in an ink pool to perform printing with good processing quality.
進而，第二目的是提供一種無需頻繁進行油墨池清掃的凹版印刷機中的油墨的調溫裝置。Further, a second object is to provide a temperature regulating device for ink in a gravure printing machine which does not require frequent ink pool cleaning.
為了達成上述目的，請求項1所記載之本發明是一種使用水性油墨之凹版印刷機中的水性油墨調溫裝置，其特徵在於：在使用水性油墨的凹版印刷機中，設有調溫油墨循環迴路，和控制迴路；上述調溫油墨循環迴路係用以使上述凹版印刷機油墨池內的油墨掉落到油墨槽內，從油墨槽內汲取上述掉落的油墨並使上述掉落的油墨穿過裝有熱媒的熱交換器，藉此將油墨的溫度調整為15℃~28℃，使上述溫度經調整之油墨返回上述油墨池內；上述控制迴路係設有用以對上述熱交換器內的熱媒溫度進行調整的熱源機，而且設有用來檢測上述油墨池內油墨溫度的感應器，對於上述熱源機的驅動量進行運算並控制熱源機的驅動，以使得上述感應器檢測出之油墨溫度始終處於15℃~28℃的範圍。In order to achieve the above object, the invention described in claim 1 is an aqueous ink tempering apparatus in a gravure printing machine using an aqueous ink, characterized in that a tempering ink cycle is provided in an intaglio printing machine using an aqueous ink. a circuit, and a control circuit; the temperature regulating ink circulation circuit is configured to drop ink in the ink pool of the gravure printing machine into the ink tank, and the ink dropped from the ink tank is taken and the ink that falls is worn Passing a heat exchanger equipped with a heat medium, thereby adjusting the temperature of the ink to 15 ° C to 28 ° C, and returning the temperature-adjusted ink to the ink pool; the control circuit is provided for the heat exchanger a heat source machine for adjusting the temperature of the heat medium, and an inductor for detecting the temperature of the ink in the ink pool, calculating the driving amount of the heat source machine and controlling the driving of the heat source machine to cause the ink detected by the sensor The temperature is always in the range of 15 ° C ~ 28 ° C.
上述本發明中，油墨池內的水性油墨一掉落到油墨槽內，便隨即將從上述油墨槽內汲取的水性油墨經由熱交換器加以加熱或冷卻，並使其返回油墨池內，因此，不僅可以將油墨池內的水性油墨的溫度調整為既定值，而且可以使油墨溫度均勻化。In the above invention, once the aqueous ink in the ink tank is dropped into the ink tank, the aqueous ink drawn from the ink tank is heated or cooled via a heat exchanger and returned to the ink tank. Not only can the temperature of the aqueous ink in the ink pool be adjusted to a predetermined value, but the temperature of the ink can be made uniform.
安裝於油墨池的油墨溫度檢測感應器不斷對油墨的溫度進行檢測並輸出至控制迴路側，控制迴路則以使所輸入的油墨溫度成為既定溫度的方式對熱源機的驅動量進行反饋控制。The ink temperature detecting sensor installed in the ink pool continuously detects the temperature of the ink and outputs it to the control circuit side, and the control circuit feedback-controls the driving amount of the heat source machine in such a manner that the input ink temperature becomes a predetermined temperature.
本發明如上所述，係於油墨池、以及用以串聯油墨槽與油墨池的循環迴路內安裝熱交換器，將上述迴路內的水性油墨的溫度不受季節影響地始終調整為15℃~28℃的範圍，並使其返回油墨池。According to the present invention, a heat exchanger is installed in the ink pool and the circulation circuit for connecting the ink tank and the ink pool in series, and the temperature of the aqueous ink in the circuit is always adjusted to 15 ° C to 28 without being affected by the season. °C range and make it return to the ink pool.
結果，將油墨池內的水性油墨的黏度始終調整為適合進行印刷的黏度，因而可以進行無漏印、擴印(不欲印刷之部分也被印刷)的高品質印刷。As a result, the viscosity of the aqueous ink in the ink pool is always adjusted to a viscosity suitable for printing, so that high-quality printing without missing printing or printing (the portion which is not printed is also printed) can be performed.
另外，將溫度經調整之水性油墨以受到循環泵加壓之狀態從循環迴路供給至油墨池內，因此在油墨池內的水性油墨會產生對流現象，藉由上述對流所致之攪拌作用可以謀求油墨溫度的均勻化。In addition, since the temperature-adjusted aqueous ink is supplied from the circulation circuit to the ink pool in a state of being pressurized by the circulation pump, the aqueous ink in the ink pool may cause convection, and the stirring effect by the convection can be sought. The temperature of the ink is uniformized.
另外，本發明係將溫度調整為15℃~28℃的水性油墨供給到油墨池內，而在油墨池內並未直接安裝熱交換器，因此不會如直接加熱進行調溫時那樣出現固態成分沉澱附著在油墨池內的底面的情況，因此，不需要進行頻繁的清掃。In addition, in the present invention, the aqueous ink adjusted to a temperature of 15 ° C to 28 ° C is supplied into the ink pool, and the heat exchanger is not directly installed in the ink pool, so that the solid content does not occur as in the case of direct heating. The precipitate adheres to the bottom surface of the ink tank, and therefore, frequent cleaning is not required.
