Description

本発明は、グラビア印刷機の印刷部においてシート材に塗布された水性インキを乾燥させる乾燥装置に関するものである。   The present invention relates to a drying apparatus for drying water-based ink applied to a sheet material in a printing unit of a gravure printing machine.

近年、環境保全等の目的で有機溶剤タイプのインキに代えて水性インキを使用することが行われているが、この水性インキを乾燥させる場合には、有機溶剤タイプに比べて格段に多い熱量が必要であり、この熱量を確保するためにシート材に吹き付けられる熱風の温度を高くすると、シート材が高温に加熱されて大きく熱膨張することが避けられない。このようにシート材が大きく熱膨張すると、複数色の水性インキを順次重ねて塗布することによりカラー印刷を行う場合に、各水性インキの塗布位置がずれる見当ずれが発生したり、シート材に皺が形成されたりし易いという問題がある。   In recent years, water-based inks have been used instead of organic solvent type inks for the purpose of environmental conservation, etc., but when this water-based ink is dried, the amount of heat is much higher than that of organic solvent type inks. It is necessary, and if the temperature of the hot air blown to the sheet material is increased in order to secure this amount of heat, it is inevitable that the sheet material is heated to a high temperature and greatly expanded. When the sheet material undergoes large thermal expansion in this way, when color printing is performed by sequentially applying a plurality of colors of water-based inks, misregistration that shifts the application position of each water-based ink may occur, or the sheet material may be damaged. There is a problem that is easily formed.

上記弊害を防止するため、下記特許文献１に示されるように、グラビア印刷機等に付設された乾燥器内に熱風を供給する熱風供給手段と、上記乾燥器から搬出されたシート材の表面温度を検出する温度検出手段と、この温度検出手段により検出されたシート材の表面温度と予め設定された基準温度との偏差に基づいて上記熱風供給手段から供給される熱風の熱量を制御する熱量制御手段とを備えた乾燥装置を用い、シート材の表面温度を一定値に維持するように上記熱風の熱量を制御することにより、上記シート材の熱膨張量が変化することに起因した見当ずれの発生や皺の発生を防止することも考えられている。
特開２００１−２４６３０６号公報 In order to prevent the above adverse effects, as shown in Patent Document 1 below, hot air supply means for supplying hot air into a dryer attached to a gravure printing machine, etc., and the surface temperature of the sheet material carried out of the dryer And a heat quantity control for controlling the amount of hot air supplied from the hot air supply means based on a deviation between the surface temperature of the sheet material detected by the temperature detection means and a preset reference temperature. And the amount of misregistration caused by the change in the amount of thermal expansion of the sheet material by controlling the amount of heat of the hot air so as to maintain the surface temperature of the sheet material at a constant value. It is also considered to prevent the occurrence of soot and soot.
JP 2001-246306 A

上記特許文献１に開示されているように、シート材の表面温度を検出する非接触式の温度センサ等からなる温度検出手段の検出値に基づき、熱風供給手段から供給される熱風の熱量を制御することにより、シート材の表面温度を一定値に維持するように構成した場合には、複数色の水性インキを重ねて塗布することによりカラー印刷を行う際におけるインキ塗布位置のずれを効果的に防止することができず、シート材の搬送速度が変化する印刷開始時に、上記見当ずれが発生することによる不良品の生成量が多くなるという問題がある。   As disclosed in Patent Document 1, the amount of hot air supplied from the hot air supply means is controlled based on the detection value of the temperature detection means including a non-contact temperature sensor that detects the surface temperature of the sheet material. By doing so, when the surface temperature of the sheet material is maintained at a constant value, it is possible to effectively shift the ink application position when performing color printing by applying a plurality of colors of water-based ink. There is a problem that the amount of defective products generated increases due to the occurrence of misregistration at the start of printing, which cannot be prevented and the sheet material conveyance speed changes.

すなわち、印刷開始時には、図６に示すように、印刷開始時点Ｔ０から一定時間に亘ってシート材の搬送速度Ｖを低速（例えば３０ｍ／ｍｉｎ程度）の見当合わせ速度Ｖ１に維持しつつ、各色毎にシート材に付された位置合わせマークに基づいて初期見当合わせを行った後、この初期見当合わせが終了した時点Ｔ１で、シート材の搬送速度Ｖを高速（例えば１５０ｍ／ｍｉｎ程度）の定常印刷速度Ｖ２まで上昇させるように構成されている。この速度上昇時に、熱風供給手段から乾燥器内に供給される熱風の温度Ｗｔを一定値、例えば６０℃程度に設定すると、シート材の単位面積当たりに供給される熱風の熱量が漸減し、これに起因して図６の破線で示すように、シート材の温度Ｓｔが次第に低下することになる。   That is, at the start of printing, as shown in FIG. 6, for each color, the sheet material conveyance speed V is maintained at a low registration speed V1 (for example, about 30 m / min) for a certain time from the printing start time T0. After the initial registration is performed based on the alignment mark attached to the sheet material, at the time T1 when the initial registration is completed, the sheet material is conveyed at a high speed (for example, about 150 m / min). It is comprised so that it may raise to speed V2. When the speed rises, if the temperature Wt of the hot air supplied from the hot air supply means into the dryer is set to a constant value, for example, about 60 ° C., the amount of heat of the hot air supplied per unit area of the sheet material gradually decreases. As a result, the temperature St of the sheet material gradually decreases as shown by the broken line in FIG.

上記シート材の温度Ｓｔが低下することによる見当ずれの発生、つまりシート材の膨張量にバラツキが生じることに起因した印刷位置のずれを防止するために、上記温度検出手段によりシート材の温度変化を検出して上記熱風の温度Ｗｔを順次上昇させる制御を実行したとしても、熱風の温度を迅速に変化させることが困難であり、シート材が適正温度に加熱されるまでに所定時間を要し、この間に上記見当ずれに起因した多量の不良品が生成されるという欠点がある。   In order to prevent the occurrence of misregistration due to a decrease in the temperature St of the sheet material, that is, the displacement of the printing position due to the variation in the expansion amount of the sheet material, the temperature detection means changes the temperature of the sheet material. Even if the control for increasing the temperature Wt of the hot air is executed sequentially, it is difficult to change the temperature of the hot air quickly, and a predetermined time is required until the sheet material is heated to an appropriate temperature. In the meantime, there is a drawback that a large amount of defective products due to the misregistration are generated.

なお、上記シート材の熱膨張量が大きく変動することに起因した見当ずれの発生を抑制するため、熱風の温度を低下させるとともに、シート材の搬送速度を遅くすることも考えられるが、このように構成した場合には、印刷速度が低下して作業効率を悪化するという問題があるため、印刷速度を低下させることなく、シート材の搬送速度が変化する印刷開始時に、見当ずれに起因した多量の不良品が生成されるのを防止できるようにすることが望まれていた。   In addition, in order to suppress the occurrence of misregistration due to large fluctuations in the thermal expansion amount of the sheet material, it is possible to reduce the temperature of the hot air and slow down the sheet material conveyance speed. In this case, there is a problem that the printing speed is lowered and the working efficiency is deteriorated. Therefore, a large amount due to misregistration is caused at the start of printing in which the conveyance speed of the sheet material is changed without reducing the printing speed. It has been desired to prevent the generation of defective products.

本発明は、上記の点に鑑みてなされたものであり、印刷速度を低下させることなく、シート材の搬送速度が変化する印刷開始時に、見当ずれに起因した多量の不良品が生成されるのを防止できるとともに、簡単な構成でシート材に塗布された水性インキを迅速かつ適正に乾燥させることが可能な乾燥装置を提供することを目的としている。   The present invention has been made in view of the above points, and a large number of defective products due to misregistration are generated at the start of printing in which the sheet material conveyance speed changes without reducing the printing speed. It is an object of the present invention to provide a drying apparatus that can prevent water-based ink applied to a sheet material with a simple configuration and can dry the water-based ink quickly and appropriately.

請求項１に係る発明は、グラビア印刷機の印刷部において水性インキが塗布されることにより印刷されたシート材が搬入される乾燥器と、上記シート材に塗布された水性インキを乾燥させるための熱風を上記乾燥器内に供給する熱風供給手段とを備えた乾燥装置において、印刷開始時点からシート材を冷却するとともに、見当合わせが終了して定常印刷速度にシート材の搬送速度を上昇させる際に、上記シート材の冷却度合を調節することによりシート材の温度を一定に維持する温度制御手段を備えたものである。   The invention according to claim 1 is a dryer for carrying in a sheet material printed by applying a water-based ink in a printing unit of a gravure printing machine, and for drying the water-based ink applied to the sheet material. In a drying apparatus having hot air supply means for supplying hot air into the dryer, when the sheet material is cooled from the start of printing and the registration is completed and the sheet material conveyance speed is increased to the steady printing speed In addition, temperature control means for maintaining the temperature of the sheet material constant by adjusting the degree of cooling of the sheet material is provided.

請求項２に係る発明は、上記請求項１記載の乾燥装置において、乾燥器内に配設されたシート材の案内ローラを冷却するとともに、その冷却度合を調節することによりシート材の温度を一定に維持するように構成したものである。また、請求項３に係る発明は、請求項１又は２記載の乾燥装置において、シート材冷却のための冷風を供給する冷風供給手段を備え、上記温度制御手段は、上記冷風供給手段を制御して、印刷開始時点から見当合わせが終了するまでは、見当合わせ終了後の定常走行時と比べて多量の冷風を供給し、見当合わせが終了して定常印刷速度にシート材の搬送速度を上昇させる際に、上記冷風の風量を減少させるようにしたものである。 According to a second aspect of the present invention, in the drying apparatus according to the first aspect, the sheet material guide roller disposed in the dryer is cooled and the temperature of the sheet material is kept constant by adjusting the cooling degree. It is comprised so that it may maintain. Further, the invention according to claim 3 is the drying apparatus according to claim 1 or 2, further comprising cold air supply means for supplying cold air for cooling the sheet material, wherein the temperature control means controls the cold air supply means. From the start of printing until registration is completed, a larger amount of cool air is supplied than during regular running after registration is completed, and registration is completed and the sheet material conveyance speed is increased to the steady printing speed. At this time, the air volume of the cold air is reduced.

上記請求項１に係る発明によれば、印刷開始時点からシート材を冷却してシート材の温度が上昇するのを抑制するとともに、見当合わせが終了して定常印刷速度にシート材の搬送速度を上昇させる際に、上記シート材の搬送速度が上昇するのに対応させてシート材の冷却度合を調節することにより、シート材の温度を一定に維持する制御を迅速かつ適正に実行することができる。したがって、上記印刷開始時に、印刷位置のずれに起因した不良品の発生を効果的に抑制し、シート材に塗布された水性インキを迅速かつ適正に乾燥させることができる。   According to the first aspect of the present invention, the sheet material is cooled from the start of printing to suppress the temperature of the sheet material from rising, and the registration is finished and the sheet material conveyance speed is set to the steady printing speed. When the sheet material is raised, the control for maintaining the temperature of the sheet material can be quickly and properly executed by adjusting the cooling degree of the sheet material in correspondence with the increase in the conveying speed of the sheet material. . Therefore, at the start of the printing, it is possible to effectively suppress the occurrence of defective products due to the displacement of the printing position, and to quickly and appropriately dry the water-based ink applied to the sheet material.

上記請求項２に係る発明によれば、印刷開始時点からシート材の案内ローラを冷却してシート材の温度上昇を間接的に抑制するとともに、見当合わせが終了して定常印刷速度にシート材の搬送速度を上昇させる際に、案内ローラの冷却度合を調節してシート材の温度を間接的に制御することにより、シート材の搬送状態に悪影響を与えることなく、印刷位置のずれに起因した不良品の発生を効果的に抑制できるという利点がある。また、上記請求項３に係る発明によれば、シート材の搬送速度が低速に設定されることによりシート材の温度が通常印刷時に比べて顕著に高くなる傾向がある初期見当合わせ時に、多量の冷風を供給し、初期見当合わせが終了した時点で、シート材の搬送速度を高速の定常印刷速度まで上昇させる際に、冷風の風量を減少させることにより、シート材の温度を迅速かつ正確に制御することができる。 According to the second aspect of the invention, the sheet material guide roller is cooled from the start of printing to indirectly suppress the temperature rise of the sheet material, and the registration is completed and the sheet material is kept at a steady printing speed. When the conveyance speed is increased, the temperature of the sheet material is indirectly controlled by adjusting the degree of cooling of the guide roller, so that there is no adverse effect on the conveyance state of the sheet material, and there is no problem caused by the printing position deviation. There is an advantage that generation of non-defective products can be effectively suppressed. In addition, according to the invention according to claim 3, a large amount of sheet material is set at the initial registration time when the sheet material conveyance speed is set to a low speed and the temperature of the sheet material tends to be significantly higher than that during normal printing. When the cold air is supplied and the initial registration is completed, the temperature of the sheet material is controlled quickly and accurately by reducing the amount of cold air when the sheet material conveyance speed is increased to a high steady printing speed. can do.

The sheet material 3 introduced from the printing unit 16 into the dryer 21 moves upward while being guided by the guide roller 22 and is led out from the carry-out port 20.

また、上記乾燥器２１の壁面には、図外の送風機および加熱源を有する熱風供給手段２５に接続された給気ダクト２６がシート搬送方向の下流部側に設置されるとともに、図外の排気処理部等に連通する排気ダクト２７が、上記給気ダクト２６の背面側に設置されている。上記給気ダクト２６は、シート材３の搬送方向に伸びる一定幅のヘッダ２８の側壁面に接続されている。このヘッダ２８には、シート材３の搬送方向と直交する方向に伸びる乾燥用の熱風吹出部２３が設けられている。   On the wall surface of the dryer 21, an air supply duct 26 connected to a hot air supply means 25 having a blower and a heating source (not shown) is installed on the downstream side in the sheet conveying direction, and exhaust air (not shown). An exhaust duct 27 communicating with the processing unit or the like is installed on the back side of the air supply duct 26. The air supply duct 26 is connected to a side wall surface of a header 28 having a constant width extending in the conveying direction of the sheet material 3. The header 28 is provided with a hot air blowing portion 23 for drying that extends in a direction orthogonal to the conveying direction of the sheet material 3.

上記熱風吹出部２３は、シート材３の搬入口１９の近傍に配列されたＶ型ノズルからなる３個の第１熱風吹出部２３ａと、シート材３の搬出口２０の近傍に設けられたＶ型ノズルからなる単一の第２熱風吹出部２３ｂと、上記第１熱風吹出部２３ａと第２熱風吹出部２３ｂとの間に配設された多数の乾燥用エアの吹出孔２９を有する多孔板ノズルからなる６個の第３熱風吹出部２３ｃとによって構成されている。   The hot air blowing section 23 includes three first hot air blowing sections 23 a composed of V-shaped nozzles arranged in the vicinity of the carry-in port 19 for the sheet material 3, and V provided in the vicinity of the carry-out port 20 for the sheet material 3. Perforated plate having a single second hot air blowing portion 23b composed of a mold nozzle and a large number of drying air blowing holes 29 disposed between the first hot air blowing portion 23a and the second hot air blowing portion 23b. It is comprised by the six 3rd hot air blowing parts 23c which consist of nozzles.

上記第１〜第３熱風吹出部２３ａ〜２３ｃは、それぞれ上記案内ローラ２２に対向する位置に配設され、取付ボルト等によって上記ヘッダ２１に着脱自在に取り付けられている。また、上記各熱風吹出部２３ａ〜２３ｃは、それぞれ所定間隔をおいて配設されることにより、各熱風吹出部２３ａ〜２３ｃから吹き出された乾燥用エアの排気を上記排気ダクト２７の設置部側に案内するための間隙３９が、相隣接する熱風吹出部２３の間に設けられている。この間隙３９は、上記乾燥用エアの排気をスムーズに案内することが可能な寸法で、上記乾燥器２１が必要以上に大型化するのを防止し得る寸法に設定されている。また、上記排気ダクト２７は、乾燥器２１の上方部においてその略幅方向全域に配設されている。   The first to third hot air blowing portions 23a to 23c are respectively disposed at positions facing the guide roller 22, and are detachably attached to the header 21 with attachment bolts or the like. The hot air outlets 23a to 23c are disposed at predetermined intervals, so that the drying air blown from the hot air outlets 23a to 23c is exhausted from the installation side of the exhaust duct 27. A gap 39 is provided between the adjacent hot air blowing parts 23. The gap 39 has a dimension that can smoothly guide the exhaust of the drying air, and is set to a dimension that can prevent the dryer 21 from becoming unnecessarily large. Further, the exhaust duct 27 is disposed in the entire upper portion of the dryer 21 in the substantially width direction.

そして、上記グラビア印刷機１を始動させる際に、上記熱風供給手段２５の加熱源および送風機を作動状態とすることにより、定常印刷時に上記シート材３に塗布された水性インキを適正に乾燥させ得るように設定された一定温度の熱風を一定の風量で、上記各熱風吹出部２３から乾燥器２１内に供給してシート材３の表面に吹き付けるとともに、排気ダクト２７の前面および底面等に形成された排気取入口から上記排気ダクト２７内に導入された上記乾燥用エアの排気を外部に導出させるようになっている。   And when starting the said gravure printing machine 1, the water source applied to the said sheet | seat material 3 at the time of regular printing can be dried appropriately by making the heating source of the said hot air supply means 25 and an air blower into an operating state. The hot air having a constant temperature set in such a manner is supplied from the hot air blowing sections 23 into the dryer 21 and blown onto the surface of the sheet material 3 with a constant air volume, and is formed on the front and bottom surfaces of the exhaust duct 27. Further, the exhaust of the drying air introduced into the exhaust duct 27 from the exhaust intake is led out to the outside.

一方、上記冷風吹出部２４は、相隣接する一対の案内ローラ２２，２２の間に配設されてその軸方向に伸びるよう設置されたヘッダ３０の各案内ローラ２２に対向する面に形成された冷風の吹出ノズルからなり、上記ヘッダ３０には、送風機を有する冷風供給手段３１が設けられた吸気ダクト３２が接続されている。そして、上記冷風供給手段３１の送風機を必要に応じて作動状態とし、上記冷風吹出部２４から各案内ローラ２２の周面に冷風を吹き付けて各案内ローラ２２を冷却することにより、この案内ローラ２２に接触するシート材３の温度を低下させるように構成されている。   On the other hand, the cold air blowing part 24 is formed on a surface facing each guide roller 22 of the header 30 which is disposed between a pair of adjacent guide rollers 22 and 22 so as to extend in the axial direction thereof. The header 30 is connected with an intake duct 32 provided with a cool air supply means 31 having a blower. The guide roller 22 is cooled by blowing the cool air from the cold air blowing section 24 to the peripheral surfaces of the guide rollers 22 to cool the guide rollers 22. It is comprised so that the temperature of the sheet | seat material 3 which contacts may be reduced.

また、上記乾燥装置１７には、乾燥器２１の搬出口２０から導出されたシート材３の張力を検出する張力検出手段３３が設けられている。この張力検出手段３３には、シート材３の搬送路に沿って配設されたピックアップローラ３４と、このピックアップローラ３４の回転支持部に設けられた歪みゲージ方式またはインダクタンス方式の張力センサ３５とからなり、上記シート材３の搬送時に、このシート材３に作用する張力を上記張力センサ３５により検出し、この検出信号を下記の制御ユニット３６に出力するように構成されている。   Further, the drying device 17 is provided with a tension detecting means 33 for detecting the tension of the sheet material 3 led out from the carry-out port 20 of the dryer 21. The tension detecting means 33 includes a pickup roller 34 disposed along the conveying path of the sheet material 3 and a strain gauge type or inductance type tension sensor 35 provided on a rotation support portion of the pickup roller 34. Thus, when the sheet material 3 is conveyed, the tension acting on the sheet material 3 is detected by the tension sensor 35, and this detection signal is output to the control unit 36 described below.

制御ユニット３６は、図４に示すように、予め設定されたシート材３の基準張力、つまりシート材３の定常印刷時に作用する張力の最適値を記憶する記憶手段３７と、上記張力検出手段３３の張力センサ３５により検出されたシート材３の張力に対応した制御信号を上記冷風供給手段３１の送風機３１ａに出力してシート材３の温度を制御する温度制御手段３８とを備えている。   As shown in FIG. 4, the control unit 36 includes a storage unit 37 that stores a preset reference tension of the sheet material 3, that is, an optimum value of the tension that is applied during steady printing of the sheet material 3, and the tension detection unit 33. Temperature control means 38 for controlling the temperature of the sheet material 3 by outputting a control signal corresponding to the tension of the sheet material 3 detected by the tension sensor 35 to the blower 31a of the cold air supply means 31.

上記温度制御手段３８は、シート材３の張力の検出値と記憶手段３７から読み出された上記基準張力とを比較し、上記張力の検出値が基準張力よりも低いことが確認された場合に、上記冷風供給手段３１の送風機３１ａを作動させるとともに、その送風量を上記張力の検出値と基準張力との偏差に対応した値に調節することにより、上記案内ローラ２２を適度に冷却してシート材３の張力を基準張力に一致させる制御を実行するように構成されている。これによってシート材３の搬送速度が変化する印刷開始時に、シート材３の定常印刷時と同温度に設定された熱風を上記熱風供給手段２５から乾燥器２１内に一定風量で供給しつつ、シート材３の温度Ｓｔを略一定に維持するとともに、シート材３の張力を基準張力と等しい値に保持する制御が実行されるようになっている。   The temperature control means 38 compares the detected tension value of the sheet material 3 with the reference tension read from the storage means 37, and when it is confirmed that the detected tension value is lower than the reference tension. The guide roller 22 is appropriately cooled by operating the air blower 31a of the cold air supply means 31 and adjusting the air flow rate to a value corresponding to the deviation between the detected tension value and the reference tension. Control is performed to match the tension of the material 3 with the reference tension. As a result, at the start of printing in which the conveyance speed of the sheet material 3 changes, the hot air set at the same temperature as that during steady printing of the sheet material 3 is supplied from the hot air supply means 25 into the dryer 21 at a constant air volume, Control is performed such that the temperature St of the material 3 is maintained substantially constant and the tension of the sheet material 3 is maintained at a value equal to the reference tension.

具体的には、図５に示すように、印刷開始時点Ｔ０から一定時間に亘ってシート材３の搬送速度Ｖを３０ｍ／ｍｉｎ程度の見当合わせ速度Ｖ１に維持しつつ、各色毎にシート材３に付された位置合わせマーク（トンボマーク）に基づいて初期見当合わせを行う際に、シート材３の定常印刷時と同温度Ｗｔに設定された熱風を上記熱風供給手段２５から乾燥器２１内に供給すると、シート材３の温度Ｓｔが通常印刷時に比べて顕著に高くなるとともに、上記シート材３の膨張量が通常印刷時よりも極端に大きくなる。この結果、シート材３に作用する張力が基準張力よりも低くなり、この状態が上記張力検出手段３３の検出値に基づいて検出されるため、上記冷風供給手段３１の送風機３１ａが作動状態となって案内ローラ２２に多量の冷風Ｂが吹き付けられることにより、シート材３が冷却されてその温度Ｓｔが一定に維持されるとともに、シート材３の張力が基準張力と等しい値に保持されるように構成されている。   Specifically, as shown in FIG. 5, the sheet material 3 is maintained for each color while maintaining the conveyance speed V of the sheet material 3 at a registration speed V1 of about 30 m / min for a predetermined time from the printing start time T0. When the initial registration is performed based on the alignment mark (register mark) attached to, hot air set at the same temperature Wt as that during steady printing of the sheet material 3 is transferred from the hot air supply means 25 into the dryer 21. When supplied, the temperature St of the sheet material 3 becomes significantly higher than that during normal printing, and the expansion amount of the sheet material 3 becomes extremely larger than that during normal printing. As a result, the tension acting on the sheet material 3 becomes lower than the reference tension, and this state is detected based on the detected value of the tension detecting means 33, so that the blower 31a of the cold air supplying means 31 is in an operating state. By blowing a large amount of cold air B on the guide roller 22, the sheet material 3 is cooled and the temperature St is maintained constant, and the tension of the sheet material 3 is maintained at a value equal to the reference tension. It is configured.

また、上記初期見当合わせが終了した時点Ｔ１で、シート材３の搬送速度Ｖを１５０ｍ／ｍｉｎ程度の高速に設定された定常印刷速度Ｖ２まで上昇させる制御が実行されることにより、シート材３の単位面積当たりに供給される熱風の熱量が漸減してシート材３の温度Ｓｔが低下し始めると、これと同時にシート材３の膨張量が減少してシート材３に作用する張力が増大する。このため、上記張力の増大が張力検出手段３３により瞬時に検出され、上記冷風供給手段３１から案内ローラ２２に吹き付けられる冷風の風量Ｂを次第に減少させる制御が上記温度制御手段３８において実行されることにより、上記見当合わせが終了して定常印刷速度Ｖ２にシート材３の搬送速度を上昇させる際に、シート材３の温度Ｓｔが一定に維持されるとともに、シート材３の張力が基準張力と等しい値に保持されるようになっている。   Further, at the time T1 when the initial registration is finished, the control for increasing the conveyance speed V of the sheet material 3 to the steady printing speed V2 set to a high speed of about 150 m / min is executed, whereby the sheet material 3 When the amount of hot air supplied per unit area gradually decreases and the temperature St of the sheet material 3 begins to decrease, the amount of expansion of the sheet material 3 decreases at the same time, and the tension acting on the sheet material 3 increases. For this reason, the increase in the tension is instantaneously detected by the tension detecting means 33, and the temperature control means 38 executes a control for gradually decreasing the amount B of the cold air blown from the cold air supply means 31 to the guide roller 22. Thus, when the registration is completed and the conveyance speed of the sheet material 3 is increased to the steady printing speed V2, the temperature St of the sheet material 3 is maintained constant, and the tension of the sheet material 3 is equal to the reference tension. It is supposed to be held in the value.

上記のようにグラビア印刷機１の印刷部１６において水性インキが塗布されることにより印刷されたシート材３が搬入される乾燥器２１と、上記シート材３に塗布された水性インキを乾燥させるための熱風を乾燥器２１内に供給する熱風供給手段２５とを備えた乾燥装置において、印刷開始時点からシート材３を冷却するとともに、見当合わせが終了して定常印刷速度にシート材３の搬送速度を上昇させる際に、上記シート材３の冷却度合を調節することによりシート材３の温度を一定に維持する温度制御手段３８を設けたため、シート材３の搬送速度が変化する印刷開始時に、見当ずれに起因した多量の不良品が生成されるという弊害を生じることなく、シート材３に塗布された水性インキを迅速かつ適正に乾燥させることができる。   As described above, the dryer 21 into which the sheet material 3 printed by applying the water-based ink in the printing unit 16 of the gravure printing machine 1 is carried in, and the water-based ink applied to the sheet material 3 is dried. In the drying apparatus provided with the hot air supply means 25 for supplying the hot air into the dryer 21, the sheet material 3 is cooled from the printing start time, and the registration is completed and the conveying speed of the sheet material 3 is brought to the steady printing speed. Since the temperature control means 38 for maintaining the temperature of the sheet material 3 constant by adjusting the degree of cooling of the sheet material 3 is provided at the time of increasing the printing speed, the registration is performed at the start of printing in which the conveyance speed of the sheet material 3 changes. The water-based ink applied to the sheet material 3 can be dried quickly and appropriately without causing the adverse effect of producing a large amount of defective products due to the deviation.

すなわち、上記張力検出手段３３により検出されたシート材３の張力と予め設定された基準張力との偏差に応じ、熱風供給手段２５から乾燥器２１内に供給される熱風の温度を調節することにより、シート材３の温度を制御するように構成した場合には、上記熱風の温度を迅速に変化させることが困難である。このため、上記張力の検出時点と、上記熱風によりシート材３の温度制御が実行される時点との間に時間差が生じることが避けられず、この時間差に応じて制御のハンチングが生じることにより、図６に示すように、シート材３が適正温度となるまでに所定の時間を要して、この間の見当ずれに起因した多量の不良品が生成されることが避けられない。   That is, by adjusting the temperature of the hot air supplied from the hot air supply means 25 into the dryer 21 in accordance with the deviation between the tension of the sheet material 3 detected by the tension detection means 33 and a preset reference tension. When the temperature of the sheet material 3 is controlled, it is difficult to quickly change the temperature of the hot air. For this reason, it is inevitable that a time difference occurs between the time point when the tension is detected and the time point when the temperature control of the sheet material 3 is performed by the hot air, and a control hunting occurs according to the time difference. As shown in FIG. 6, it is inevitable that a predetermined time is required until the sheet material 3 reaches an appropriate temperature, and a large amount of defective products are generated due to misregistration during this time.

これに対して図５に示すように、印刷開始時点Ｔ０から一定時間に亘ってシート材３の搬送速度Ｖが低速に設定されることにより、シート材３の温度Ｓｔが通常印刷時に比べて顕著に高くなる傾向がある初期見当合わせ時に、上記冷風供給手段３１の送風機３１ａを作動させて案内ローラ２２に多量の冷風Ｂを吹き付けて案内ローラ２２の温度を低下させるとともに、上記初期見当合わせが終了した時点Ｔ１で、シート材３の搬送速度Ｖを高速の定常印刷速度Ｖ２まで上昇させる際に、この搬送速度Ｖの上昇に伴ってシート材３の単位面積当たりに供給される熱風の熱量が漸減するのに応じ、上記冷風供給手段３１から案内ローラ２２に吹き付けられる冷風の風量Ｂを減少させることにより、上記案内ローラ２２によるシート材３の冷却度合を正確に調節するように構成した場合には、シート材３の温度を迅速かつ正確に制御することができる。したがって、印刷速度を低下させる等の手段を講じることなく、印刷開始時に、シート材３の温度Ｓｔが低下することによる見当ずれの発生、つまりシート材３の膨張量にバラツキが生じることに起因した印刷位置のずれを適正に防止し、上記見当ずれに起因した多量の不良品が生成されるの効果的に抑制できるという利点がある。   On the other hand, as shown in FIG. 5, the temperature St of the sheet material 3 is conspicuous compared with that during normal printing by setting the conveyance speed V of the sheet material 3 to be low for a certain time from the printing start time T0. At the time of initial registration that tends to increase, the blower 31a of the cold air supply means 31 is operated to blow a large amount of cold air B on the guide roller 22 to lower the temperature of the guide roller 22, and the initial registration is completed. When the conveyance speed V of the sheet material 3 is increased to the high steady printing speed V2 at the time T1, the amount of hot air supplied per unit area of the sheet material 3 gradually decreases as the conveyance speed V increases. Accordingly, the cooling rate of the sheet material 3 by the guide roller 22 is reduced by reducing the amount B of cool air blown from the cold air supply means 31 to the guide roller 22. When configured to adjust correctly, it is possible to control the temperature of the sheet material 3 quickly and accurately. Therefore, the occurrence of misregistration due to the decrease in the temperature St of the sheet material 3 at the start of printing, that is, the variation in the expansion amount of the sheet material 3 occurs without taking measures such as reducing the printing speed. There is an advantage that it is possible to appropriately prevent the displacement of the printing position and effectively suppress the generation of a large amount of defective products due to the misregistration.

なお、上記のように印刷開始時点から初期見当合わせが終了するまでの間、案内ローラ２２に多量の冷風Ｂを吹き付けるとともに、その風量を制御することにより、シート材３の冷却度合を間接的に制御するようにした上記実施形態に代え、シート材３の裏面に冷風を吹き付けてシート材３の温度Ｓｔを直接的に制御するように構成してもよい。このようにシート材３の裏面に冷風を吹き付けるように構成した場合には、シート材３の冷却度合を効果的に調節することができるという利点を有する反面、上記冷風の吹付圧が高いと、シート材３が案内ローラ２２から離間して搬送状態が不安定になり易いという欠点がある。したがって、シート材３の搬送状態を安定させるためには、案内ローラ２２に多量の冷風Ｂを吹き付けるとともに、その風量を制御することにより、シート材３の冷却度合を調節するように構成することが好ましい。なお、印刷開始時点から初期見当合わせが終了するまでの間、上記案内ローラ２２内に冷却水等からなる冷媒を供給するとともに、この冷媒の供給量を制御することにより、シート材３の冷却度合を間接的に調節するようにようにしてもよい。   It should be noted that a large amount of cool air B is blown onto the guide roller 22 from the start of printing to the end of the initial registration as described above, and the amount of cooling of the sheet material 3 is indirectly controlled by controlling the amount of air. Instead of the embodiment described above, the temperature St of the sheet material 3 may be directly controlled by blowing cool air to the back surface of the sheet material 3. Thus, when it is configured to blow cold air on the back surface of the sheet material 3, it has an advantage that the degree of cooling of the sheet material 3 can be effectively adjusted, but when the blowing pressure of the cold air is high, There is a disadvantage that the sheet material 3 is separated from the guide roller 22 and the conveyance state is likely to become unstable. Therefore, in order to stabilize the conveyance state of the sheet material 3, a large amount of cold air B is blown onto the guide roller 22 and the air volume is controlled to adjust the cooling degree of the sheet material 3. preferable. It should be noted that a cooling medium such as cooling water is supplied into the guide roller 22 from the start of printing to the end of the initial registration, and the amount of cooling of the sheet material 3 is controlled by controlling the supply amount of this cooling medium. May be adjusted indirectly.

また、上記実施形態では、乾燥器２１内に搬入されたシート材３の張力を検出する張力検出手段３３を設け、この張力検出手段３３により検出されたシート材３の張力が予め設定された基準張力よりも低い場合に、上記冷風供給手段３１を作動させて案内ローラ２２に冷風を吹き付けることにより、シート材３の温度を低下させるように構成したため、シート材３の偏った位置に水性インキが部分的に塗布されるとともに、この塗布位置が印刷パターンの変化に応じて移動する場合においても、シート材３の温度変化に対応して変動するシート材３の張力を簡単な構成で正確に検出し、この張力の変動に対応させて上記冷風の風量を制御する等により、シート材３の冷却度合を正確に調節できるという利点がある。   In the above embodiment, the tension detection means 33 for detecting the tension of the sheet material 3 carried into the dryer 21 is provided, and the tension of the sheet material 3 detected by the tension detection means 33 is a preset reference. Since the temperature of the sheet material 3 is lowered by operating the cold air supply means 31 and blowing the cold air to the guide roller 22 when the tension is lower than the tension, the water-based ink is applied to the uneven position of the sheet material 3. Even when it is partially applied and the application position moves in accordance with the change of the printing pattern, the tension of the sheet material 3 that fluctuates corresponding to the temperature change of the sheet material 3 can be accurately detected with a simple configuration. In addition, there is an advantage that the degree of cooling of the sheet material 3 can be accurately adjusted by controlling the amount of the cold air corresponding to the variation in tension.

すなわち、上記張力検出手段３３に代えて非接触式の温度センサ等からなる温度検出手段を設け、この温度検出手段の検出値に対応させて上記冷風の風量を制御する等により、印刷開始時にシート材３の温度を一定に維持するように構成することも可能であるが、この場合には、上記印刷パターンの変化に対応させて温度検出手段の設置位置を移動させる等の複雑な構成を採用しなければ必要個所の温度変化、つまり上記水性インキの塗布位置の温度変化を正確に検出することができないため、シート材３の温度変化に対応させて上記冷風の風量を適正に制御することが困難であるという欠点がある。このため、上記のように乾燥器２１内に搬入されたシート材３の張力を張力検出手段３３により検出し、その検出値に対応させて上記冷風供給手段３１から案内ローラ２２に吹き付けられる冷風の風量等を制御することにより、印刷パターンの変化に対応じて水性インクの塗布位置が変化した場合においても、シート材３の温度が低下することに起因した見当ずれの発生、つまりシート材３の膨張量にバラツキが生じることによる印刷位置のずれを簡単な構成で迅速かつ適正に抑制できるように構成することが望ましい。   That is, instead of the tension detection means 33, a temperature detection means comprising a non-contact type temperature sensor or the like is provided, and the amount of the cold air is controlled in accordance with the detection value of the temperature detection means, so that the sheet is printed at the start of printing. Although it is possible to keep the temperature of the material 3 constant, in this case, a complicated structure such as moving the installation position of the temperature detecting means in accordance with the change of the print pattern is adopted. If this is not done, it is not possible to accurately detect the temperature change at the required location, that is, the temperature change at the application position of the water-based ink. Therefore, the air volume of the cold air can be appropriately controlled in accordance with the temperature change of the sheet material 3. There is a drawback that it is difficult. For this reason, the tension of the sheet material 3 carried into the dryer 21 as described above is detected by the tension detection means 33, and the cold air blown from the cold air supply means 31 to the guide roller 22 in accordance with the detected value. By controlling the air volume and the like, even when the application position of the water-based ink is changed corresponding to the change of the printing pattern, the occurrence of misregistration caused by the temperature of the sheet material 3 being lowered, that is, the sheet material 3 It is desirable that the shift of the printing position due to the variation in the expansion amount can be quickly and appropriately suppressed with a simple configuration.
