Description

本発明は、可撓性のフィルムを、何らかの前工程と後工程において、それぞれ異なる速度で搬送する場合に、これら前後工程の速度差を調整するためのフィルム溜め方法、及びバッファ装置に関する。   The present invention relates to a film storage method and a buffer device for adjusting a speed difference between preceding and following processes when a flexible film is conveyed at different speeds in some pre-process and post-process.

スクリーン印刷装置を用いてフィルムの上面に導電パターンを印刷し、同フィルムをドライヤで乾燥させる場合、スクリーン印刷装置から断続的に搬出されるフィルムが、ドライヤを一定の速度で通過する。このため、フィルムがスクリーン印刷装置から繰出される速度と、同フィルムがドライヤに引込まれる速度との差を調整できるように、スクリーン印刷装置とフィルムとの間に、ダンサロールが設けられる。ダンサロールに係る技術は特許文献１に開示されている。   When a conductive pattern is printed on the upper surface of a film using a screen printing apparatus and the film is dried with a dryer, the film intermittently carried out from the screen printing apparatus passes through the dryer at a constant speed. For this reason, a dancer roll is provided between the screen printing apparatus and the film so that the difference between the speed at which the film is fed from the screen printing apparatus and the speed at which the film is drawn into the dryer can be adjusted. A technique related to a dancer roll is disclosed in Patent Document 1.

例えば、図４に示すように、上流サクションロールＲ１と、下流サクションロールＲ２との間に、ダンサロール４０を設ける。上流サクションロールＲ１を電動機で矢印Ｆ方向に回転させることにより、スクリーン印刷装置から搬出されるフィルム１を下方へ案内し、下流サクションロールＲ２を電動機で矢印Ｆ’方向に回転させることにより、フィルム１をダンサロール４０の上方へ牽引する。   For example, as shown in FIG. 4, a dancer roll 40 is provided between the upstream suction roll R1 and the downstream suction roll R2. By rotating the upstream suction roll R1 in the direction of arrow F with an electric motor, the film 1 transported from the screen printing apparatus is guided downward, and by rotating the downstream suction roll R2 in the direction of arrow F ′ with an electric motor, film 1 Is pulled above the dancer roll 40.

この場合、ダンサロール４０が導電パターンに触れるのを避けなければならない。そこで、フィルム１の幅方向の両縁部が印刷の余白になることに着目し、特許文献２に示すようなフィルム１の両縁部に接触する２つのローラを、ダンサロールに代えて適用することが考えられる。
特開２００２−８７６７０号公報 特開２００２−１７９３０５号公報 In this case, the dancer roll 40 must be prevented from touching the conductive pattern. Therefore, paying attention to the fact that both edges in the width direction of the film 1 become printing margins, two rollers contacting the both edges of the film 1 as shown in Patent Document 2 are applied instead of the dancer roll. It is possible.
JP 2002-87670 A JP 2002-179305 A

スクリーン印刷装置がフィルム１に印刷を施す動作を終えたところで、上流サクションロールＲ１は、下流サクションロールＲ２よりも速い回転速度で回転する。これに従ってフィルム１の撓み量が増大し、ダンサロール４０は自重で下降する。しかしながら、フィルム１の両縁部が、ダンサロールに代わる上記２つのローラによって押し下げられると、この反力に起因してフィルム１の両縁部の間に皺が発生するという問題が起こる。   When the screen printing apparatus finishes printing the film 1, the upstream suction roll R1 rotates at a higher rotational speed than the downstream suction roll R2. Accordingly, the amount of bending of the film 1 increases, and the dancer roll 40 descends by its own weight. However, when the two edges of the film 1 are pushed down by the two rollers in place of the dancer roll, there arises a problem that wrinkles occur between the two edges of the film 1 due to the reaction force.

本発明は、以上に述べた実情に鑑みて為されたものであり、その目的とするところは、フィルムを適度に緊張させ皺の発生を予防できるフィルム溜め方法、及びバッファ装置を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a film storage method and a buffer device that can moderately tension the film and prevent wrinkles. is there.

本発明に係るフィルム溜め方法は、幅方向の両縁部を有する長尺状のフィルムを、その長手方向に搬送し、前記フィルムの両縁部に、一対のテンションロールを前記フィルムの上方からそれぞれ接触させ、前記一対のテンションロールが前記フィルムを押し下げる工程で、前記一対のテンションロールの下降及び停止を交互に繰り返すことを特徴とする。   In the film storage method according to the present invention, a long film having both edges in the width direction is transported in the longitudinal direction, and a pair of tension rolls are provided on both edges of the film from above the film. In the step of bringing the pair of tension rolls into contact and pressing down the film, the pair of tension rolls are alternately lowered and stopped alternately.

本発明に係るバッファ装置は、幅方向の両縁部を有する長尺状のフィルムが、その長手方向に搬送される過程で、前記フィルムを下方に撓ませるものであって、前記フィルムの両縁部にその上方から接触する一対のテンションロールと、前記一対のテンションロールの重さに相当する釣合錘の荷重を前記一対のテンションロールに上向きに加える保持手段と、前記一対のテンションロールを下降させる動力を発生する駆動手段と、前記駆動手段の動力を前記一対のテンションロールに伝達し又は遮断するクラッチとを備え、前記クラッチが前記駆動手段の動力を前記一対のテンションロールに伝達することにより、前記一対のテンションロールを下降させ、前記クラッチが前記駆動手段の動力を遮断した状態で、前記一対のテンションロールが、前記保持手段の釣合錘に釣り合うことを特徴とする。   In the buffer device according to the present invention, a long film having both edges in the width direction is bent in the process of being conveyed in the longitudinal direction, and both edges of the film are A pair of tension rolls that come into contact with the part from above, holding means for applying a load of a counterweight corresponding to the weight of the pair of tension rolls upward to the pair of tension rolls, and lowering the pair of tension rolls Drive means for generating power to be driven, and a clutch for transmitting or interrupting the power of the drive means to the pair of tension rolls, and the clutch transmits the power of the drive means to the pair of tension rolls. The pair of tension rolls in a state where the pair of tension rolls are lowered and the clutch cuts off the power of the driving means. Characterized in that the balance in the counterweight of the holding means.

更に、本発明に係るバッファ装置は、前記クラッチが、前記駆動手段の動力を前記一対のテンションロールに伝達する動作と、前記駆動手段の動力を遮断する動作とを、交互に繰り返すことを特徴とする。   Furthermore, the buffer device according to the present invention is characterized in that the clutch alternately repeats an operation of transmitting the power of the driving means to the pair of tension rolls and an operation of interrupting the power of the driving means. To do.

本発明に係るフィルム溜め方法によれば、一対のテンションロールがそれぞれフィルムの両縁部を押し下げるとき、フィルムの両縁部の間に皺が発生しようとするが、一対のテンションロールが停止した時点で、一対のテンションロールがフィルムを押し下げる力をフィルムから除けるので、フィルムの皺を未然に防止することができる。   According to the film reservoir method of the present invention, when a pair of tension rolls push down both edges of the film, wrinkles are likely to occur between the edges of the film, but when the pair of tension rolls are stopped. Thus, the force that the pair of tension rolls pushes down the film can be removed from the film, so that the film can be prevented from wrinkling.

例えば、スクリーン印刷装置で導電パターンをフィルムの上面に印刷し、同フィルムがドライヤに搬送される場合、一対のテンションロールはフィルムの上面の両縁部にそれぞれ接触する。これらのテンションロールが下方に変位する工程で、一対のテンションロールの下降及び停止を交互に繰り返すことにより、フィルムに皺を発生させることなく、フィルムを下方へ撓ませることができる。また、上記の工程でフィルムを撓ませた分、スクリーン印刷装置からドライヤに搬送されるフィルムの速度差を吸収することができる。   For example, when a conductive pattern is printed on the upper surface of a film by a screen printing apparatus and the film is conveyed to a dryer, the pair of tension rolls are in contact with both edges of the upper surface of the film. By alternately lowering and stopping the pair of tension rolls in the process of displacing the tension rolls downward, the film can be bent downward without causing wrinkles on the film. Further, the difference in speed of the film conveyed from the screen printing apparatus to the dryer can be absorbed by the amount of bending of the film in the above process.

本発明に係るバッファ装置によれば、クラッチが駆動手段の動力を一対のテンションロールに伝達したとき、一対のテンションロールがそれぞれ下降し、フィルムの両縁部を押し下げる。これにより、フィルムの両縁部の間に皺が発生しようとするが、クラッチが駆動手段の動力を遮断した時点で、一対のテンションロールが停止するので、上記のようにフィルムの皺を未然に防止することができる。   According to the buffer device of the present invention, when the clutch transmits the power of the driving means to the pair of tension rolls, the pair of tension rolls are lowered to push down both edges of the film. As a result, wrinkles are likely to occur between both edges of the film, but when the clutch cuts off the power of the driving means, the pair of tension rolls stop, so that the film wrinkles as described above. Can be prevented.

更に、本発明に係るバッファ装置によれば、クラッチが、駆動手段の動力を一対のテンションロールに伝達する動作と、駆動手段の動力を遮断する動作とを交互に繰り返すことができる。これにより、フィルムに皺を発生させることなく、フィルムを下方へ撓ませ、例えばスクリーン印刷装置からドライヤに搬送されるフィルムの速度差を吸収することができる。   Furthermore, according to the buffer device of the present invention, the clutch can alternately repeat the operation of transmitting the power of the driving means to the pair of tension rolls and the operation of interrupting the power of the driving means. Thereby, without generating wrinkles in the film, the film can be bent downward, and for example, a speed difference of the film conveyed from the screen printing apparatus to the dryer can be absorbed.

図１，２は、上流サクションロールＲ１及び下流サクションロールＲ２の間で長尺状のフィルム１を下方へ撓ませるバッファ装置２を示している。図中の矢印Ｔ方向は、フィルム１の長手方向であり、フィルム１の幅方向に直交する方向である。フィルム１は、その幅方向の両縁部３の間の領域に印刷が施される。以下に記す「一対」は、互いに同じ２つの要素がフィルム１の幅方向に隔たり相対向していることを意味する。   1 and 2 show a buffer device 2 that bends a long film 1 downward between an upstream suction roll R1 and a downstream suction roll R2. An arrow T direction in the figure is a longitudinal direction of the film 1 and is a direction orthogonal to the width direction of the film 1. The film 1 is printed in a region between both edges 3 in the width direction. The “pair” described below means that the same two elements are opposed to each other in the width direction of the film 1.

バッファ装置２は、フィルム１の両縁部３にそれぞれ接触する一対のテンションロール４と、一対のテンションロール４の重さを一対の釣合錘５の荷重によって打ち消す保持手段６と、一対のテンションロール４を下降させる動力を発生する駆動手段７と、駆動手段７の動力を一対のテンションロール４に伝達し又は遮断するクラッチ８とを備える。   The buffer device 2 includes a pair of tension rolls 4 that are in contact with both edges 3 of the film 1, a holding means 6 that counteracts the weight of the pair of tension rolls 4 with a load of the pair of counterweights 5, and a pair of tensions A driving unit 7 that generates power for lowering the roll 4 and a clutch 8 that transmits or interrupts the power of the driving unit 7 to the pair of tension rolls 4 are provided.

一対のテンションロール４の重さには、これらを回転自在に支持する支軸４１と、支軸４１の両端に設けられた一対のスライダ４２との重さが含まれる。一対のテンションロール４は、支軸４１にボルト等で締め付けられている。このボルト等を緩めれば、一対のテンションロール４を支軸４１に沿って移動させ、一対のテンションロール４同士の間隔を調節できる。一対のテンションロール４からフィルム１が逸れるのを防止するために、一対のテンションロール４の外側に鍔部４３を設けても良い。符号４４，４５は、バッファ装置２のフレーム２１の適所に設けられたガイドローラを指している。   The weight of the pair of tension rolls 4 includes the weight of a support shaft 41 that rotatably supports these and a pair of sliders 42 provided at both ends of the support shaft 41. The pair of tension rolls 4 are fastened to the support shaft 41 with bolts or the like. If the bolts are loosened, the pair of tension rolls 4 can be moved along the support shaft 41 to adjust the distance between the pair of tension rolls 4. In order to prevent the film 1 from deviating from the pair of tension rolls 4, a flange 43 may be provided outside the pair of tension rolls 4. Reference numerals 44 and 45 denote guide rollers provided at appropriate positions on the frame 21 of the buffer device 2.

また、バッファ装置２のフレーム２１には支柱２２が設けられ、一対のガイドレール２３は直立する姿勢で支柱２２に固定されている。一対のスライダ４２は、それぞれ一対のガイドレール２３に係合しているので、一対のテンションロール４は、フレーム２１に対して昇降自在である。保持手段６は、支柱２２の上部に一対の回転輪６１を設け、フレーム２１の底部に軸受された連結軸６２の両端に一対の回転輪６３を設け、これらの回転輪６１，６３に、端部６４を有する一対の牽体６５を巻掛したものである。符号６６は、釣合錘５を昇降自在に案内する一対のガイドレールを指している。   Further, the frame 21 of the buffer device 2 is provided with a support column 22, and the pair of guide rails 23 are fixed to the support column 22 in an upright posture. Since the pair of sliders 42 are respectively engaged with the pair of guide rails 23, the pair of tension rolls 4 can be raised and lowered with respect to the frame 21. The holding means 6 is provided with a pair of rotating wheels 61 at the top of the support column 22, and a pair of rotating wheels 63 at both ends of a connecting shaft 62 that is supported at the bottom of the frame 21. A pair of checkers 65 having a portion 64 is wound around. Reference numeral 66 denotes a pair of guide rails for guiding the counterweight 5 so as to be movable up and down.

一対の牽体６５の端部６４は一対の釣合錘５に接合され、一対の牽体６５の途中に一対のスライダ４２が取付けられている。一対の牽体６５は、釣合錘５の荷重を一対のスライダ４２に伝え、一対のテンションロール４、支軸４１、及び一対のスライダ４２に、一対の釣合錘５の荷重を上向きに加える役割を果たしている。回転輪６１，６３としてタイミングプーリ又はスプロケット等を適用し、牽体６５としてタイミングベルト又はチェーン等を適用しても良い。   End portions 64 of the pair of checkers 65 are joined to the pair of counterweights 5, and a pair of sliders 42 are attached in the middle of the pair of checkers 65. The pair of checkers 65 transmits the load of the counterweight 5 to the pair of sliders 42, and applies the load of the pair of counterweights 5 upward to the pair of tension rolls 4, the support shafts 41, and the pair of sliders 42. Playing a role. A timing pulley or a sprocket or the like may be applied as the rotating wheels 61 and 63, and a timing belt or a chain or the like may be applied as the check body 65.

駆動手段７は、サーボモータ等から成る電動機７１と、電動機７１の出力軸７２にクラッチ８を介して接続された駆動輪７３と、連結軸６２に取付けられた従動輪７４と、駆動輪７３及び従動輪７４に巻掛された無端状の牽体７５とを備える。電動機７１はフレーム２１の底部に固定しても良い。電動機７１の出力軸７２が図２の矢印Ｄ方向へ回転するに従って回転輪６１，６３が回転する。これにより、一対の牽体６５には、一対のスライダ４２を下降させる張力と同時に、釣合錘５を上昇させる張力が発生し、一対のスライダ４２と共に一対のテンションロール４が下降する。クラッチ８は、電動機７１の出力軸７２から駆動輪７３に伝達される動力（回転力）の大きさを自在に調節できる電磁クラッチである。クラッチ８の動作は、コンピューター等から送出される電気信号に基づき達成されるようにしても良い。   The driving means 7 includes an electric motor 71 composed of a servo motor, a driving wheel 73 connected to the output shaft 72 of the electric motor 71 via the clutch 8, a driven wheel 74 attached to the connecting shaft 62, a driving wheel 73, And an endless checker 75 wound around the driven wheel 74. The electric motor 71 may be fixed to the bottom of the frame 21. The rotating wheels 61 and 63 rotate as the output shaft 72 of the electric motor 71 rotates in the direction of arrow D in FIG. As a result, a tension that raises the counterweight 5 is generated in the pair of checkers 65 simultaneously with a tension that lowers the pair of sliders 42, and the pair of tension rolls 4 are lowered together with the pair of sliders 42. The clutch 8 is an electromagnetic clutch that can freely adjust the magnitude of the power (rotational force) transmitted from the output shaft 72 of the electric motor 71 to the drive wheels 73. The operation of the clutch 8 may be achieved based on an electrical signal sent from a computer or the like.

以上に述べたバッファ装置２を稼動させるとき、先ず電動機７１を起動し、電動機７１の出力軸７２を回転させる。そして、クラッチ８が駆動手段７の動力を一対のテンションロール４に伝達したとき、一対のテンションロール４が下降し、クラッチ８が駆動手段７の動力を遮断したとき、一対のテンションロール４が一対の釣合錘５と釣り合う状態となって停止する。また、バッファ装置２により実現できるフィルム溜め方法は、次の通りである。   When operating the buffer device 2 described above, first, the motor 71 is started and the output shaft 72 of the motor 71 is rotated. When the clutch 8 transmits the power of the driving means 7 to the pair of tension rolls 4, the pair of tension rolls 4 is lowered, and when the clutch 8 interrupts the power of the driving means 7, the pair of tension rolls 4 is paired. It stops in a state of balancing with the counterweight 5. The film storage method that can be realized by the buffer device 2 is as follows.

例えば、スクリーン印刷装置がフィルム１に印刷を施した直後、図２に示す上流サクションロールＲ１は、下流サクションロールＲ２よりも速い回転速度で矢印Ｆ方向に回転する。これに従ってフィルム１の撓み量が徐々に増大する工程で、クラッチ８は、駆動手段７の動力を一対のテンションロール４に伝達する動作と、駆動手段７の動力を遮断する動作を交互に繰り返すことにより、一対のテンションロール４が下降及び停止を交互に繰り返す。   For example, immediately after the screen printing apparatus prints on the film 1, the upstream suction roll R1 shown in FIG. 2 rotates in the direction of arrow F at a faster rotational speed than the downstream suction roll R2. In the process of gradually increasing the amount of bending of the film 1 according to this, the clutch 8 alternately repeats the operation of transmitting the power of the driving means 7 to the pair of tension rolls 4 and the operation of interrupting the power of the driving means 7. Thus, the pair of tension rolls 4 alternately repeats descending and stopping.

このようなフィルム溜め方法によれば、一対のテンションロール４が下降するとき、図１に示すフィルム１の両縁部３が一対のテンションロール４に押し下げられ、フィルム１の両縁部３の間に皺が発生しようとするが、一対のテンションロール４が停止した時点で、一対のテンションロール４がフィルム１を押し下げる力がフィルム１から除かれる。このため、フィルム１の両縁部３の間に皺が発生することはない。一対のテンションロール４が下限まで降下したところで、クラッチ８は駆動手段７の動力を遮断する。   According to such a film reservoir method, when the pair of tension rolls 4 are lowered, both edges 3 of the film 1 shown in FIG. However, when the pair of tension rolls 4 are stopped, the force by which the pair of tension rolls 4 pushes down the film 1 is removed from the film 1. For this reason, wrinkles do not occur between both edge portions 3 of the film 1. When the pair of tension rolls 4 are lowered to the lower limit, the clutch 8 cuts off the power of the driving means 7.

続いて、図３に示すように、上流サクションロールＲ１が停止し、下流サクションロールＲ２が矢印Ｆ’方向に回転するに従ってフィルム１の撓み量が徐々に減少する。この工程で、クラッチ８は駆動手段７の動力を遮断し続けているので、フィルム１の撓みが小さくなる従って一対のテンションロール４は、フィルム１に押し上げられて上昇する。また、クラッチ８が駆動手段７の動力を遮断している間、一対のテンションロール４の重さは釣合錘５によって打ち消されるので、一対のテンションロール４を押し上げるフィルム１が、一対のテンションロール４の反力を強く受けることはなく、フィルム１に皺が発生することはない。   Subsequently, as shown in FIG. 3, the deflection amount of the film 1 gradually decreases as the upstream suction roll R <b> 1 stops and the downstream suction roll R <b> 2 rotates in the arrow F ′ direction. In this step, since the clutch 8 continues to cut off the power of the driving means 7, the bending of the film 1 is reduced, so that the pair of tension rolls 4 are pushed up by the film 1 and rise. Further, since the weight of the pair of tension rolls 4 is canceled out by the counterweight 5 while the clutch 8 cuts off the power of the driving means 7, the film 1 that pushes up the pair of tension rolls 4 becomes the pair of tension rolls. No strong reaction force 4 is generated, and no wrinkles are generated on the film 1.

尚、本発明は、その趣旨を逸脱しない範囲で当業者の知識に基づいて種々なる改良、修正、又は変形を加えた態様で実施できる。例えば、一対のスライダ４２が昇降できる範囲の下限又は上限にあることをセンサで検出するようにしても良い。   It should be noted that the present invention can be implemented in variously modified, modified, or modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the sensor may detect that the slider 42 is at the lower limit or the upper limit of the range in which the slider 42 can move up and down.

本発明は、フィルムの材質又は用途に関わらず、フィルムをその搬送の途中で撓ませるのに有益な技術である。   The present invention is a useful technique for bending a film in the middle of its conveyance regardless of the material or use of the film.
