Description

本発明は、ウエブのアキューム装置に関するものである。 The present invention relates to a web accumulator.

フィルム、紙、布帛などの長尺状のウエブの搬送ラインにおいて、ウエブを溜め込むためのアキューム装置がある。このアキューム装置は、装置の上流側の走行速度を変えることなく、装置の下流側の走行速度を減速、又は、停止させる。 In a long web transport line for films, papers, fabrics, etc., there is an accumulator for accumulating the web. This accumulator reduces or stops the traveling speed on the downstream side of the device without changing the traveling speed on the upstream side of the device.

そのために、アキューム装置のフレームには、第１固定ローラと第２固定ローラが設けられ、この第１固定ローラと第２固定ローラの間に移動ローラが設けられている。そして、ウエブは、第１固定ローラ、移動ローラ、第２固定ローラに架け渡されて搬送され、ウエブを溜め込む場合には、移動ローラを上下方向に移動させ、ウエブの搬送距離を大きくする。 Therefore, the frame of the accumulator device is provided with a first fixed roller and a second fixed roller, and a moving roller is provided between the first fixed roller and the second fixed roller. Then, the web is carried over the first fixed roller, the moving roller, and the second fixed roller, and when the web is stored, the moving roller is moved in the vertical direction to increase the carrying distance of the web.

しかし、従来のアキューム装置は、第１固定ローラ、移動ローラ、第２固定ローラ共に左右両側から回転自在に支持する構造であるため、アキューム装置の設置に広いスペースが必要であり、また、第１固定ローラ、移動ローラ、第２固定ローラにウエブを通紙がし難いという問題点があった。 However, since the conventional accumulator has a structure in which the first fixed roller, the moving roller, and the second fixed roller are rotatably supported from both the left and right sides, a large space is required for installing the accumulator, and the first There is a problem that it is difficult to pass the web through the fixed roller, the moving roller, and the second fixed roller.

そこで本発明は上記問題点に鑑み、アキューム装置の設置スペースを小さくすることができると共に、ウエブの通紙が行い易いウエブのアキューム装置を提供することを目的とする。 Therefore, in view of the above problems, it is an object of the present invention to provide a web accumulator in which the installation space of the accumulator can be reduced and the web can be easily passed through.

本発明は、フレームと、前記フレームに立設された支持壁と、前記支持壁に一方の軸のみが回転自在に支持された少なくとも１本の第１固定ローラと、前記支持壁に一方の軸のみが回転自在に支持された少なくとも１本の第２固定ローラと、前記第１固定ローラと前記第２固定ローラとの間であって、前記支持壁に対し上下動自在に設けられた移動支持部と、前記移動支持部に一方の軸のみが回転自在に支持された少なくとも１本の移動ローラと、前記移動支持部を上下動させる駆動手段と、を有し、前記第１固定ローラと第２固定ローラが同じ高さに設けられ、走行するウエブは、前記第１固定ローラ、前記移動ローラ、前記第２固定ローラの順番に架け渡され、前記支持壁に切欠き部が設けられ、前記切欠き部に沿って前記移動支持部が上下動自在に設けられ、前記切欠き部の上部と前記移動支持部の上部との間の開口部を閉塞する上シャッタ部材が設けられ、前記切欠き部の下部と前記移動支持部の下部との間の開口部を閉塞する下シャッタ部材が設けられた、ウエブのアキューム装置である。 The present invention includes a frame, a support wall erected on the frame, at least one first fixed roller in which only one shaft is rotatably supported on the support wall, and one shaft on the support wall. A movable support provided between the first fixed roller and the second fixed roller, which is rotatably supported only by the first fixed roller and the second fixed roller, and which is rotatably provided with respect to the support wall. The first fixed roller and the first fixed roller are provided with a portion, at least one moving roller in which only one shaft is rotatably supported by the moving support portion, and a driving means for moving the moving support portion up and down. The two fixed rollers are provided at the same height, and the traveling web is bridged in the order of the first fixed roller, the moving roller, and the second fixed roller, and a notch is provided in the support wall.

まず、アキューム装置１が動作していないときは、図１に示すように、第１移動ローラ３８と第２移動ローラ４０は、第１切欠き部４２と第２切欠き部７２の上端部に位置している。この場合に、第１切欠き部４２と第２切欠き部７２は、下シャッタ部材６８、下シャッタ部材９８によって覆われている。 First, when the accumulator 1 is not operating, as shown in FIG. 1, the first moving roller 38 and the second moving roller 40 are placed on the upper ends of the first notch 42 and the second notch 72. positioned. In this case, the first notch 42 and the second notch 72 are covered by the lower shutter member 68 and the lower shutter member 98.

次に、図１に示すように、長尺状のウエブＷを搬入口２４から通し、片持ち状態の第１固定ローラ３２、第１移動ローラ３８、第２固定ローラ３４、第２移動ローラ４０、第３固定ローラ３６に、右側から架け渡す。そして、搬出口２６から搬出する。 Next, as shown in FIG. 1, a long web W is passed through the carry-in inlet 24, and the cantilevered first fixed roller 32, first moving roller 38, second fixed roller 34, and second moving roller 40 are passed. , It is bridged to the third fixed roller 36 from the right side. Then, it is carried out from the carry-out port 26.

次に、図１に示すように、ウエブＷを通常の走行速度で走行させると、ウエブＷは２本の第１固定ローラ３２の上部、２本の第１移動ローラ３８、２本の第２固定ローラ３４の上部、２本の第２移動ローラ４０の下部、２本の第３固定ローラ３６の上部を通って走行する。 Next, as shown in FIG. 1, when the web W is run at a normal traveling speed, the web W is the upper part of the two first fixed rollers 32, the two first moving rollers 38, and the second second. It travels through the upper part of the fixed roller 34, the lower part of the two second moving rollers 40, and the upper part of the two third fixed rollers 36.

次に、下流側の巻取り装置などの動作状態に応じてウエブＷを減速させたり、又は、停止させるときに、アキューム装置１が動作させる。図２に示すように、この減速又は停止させるウエブＷの走行速度に応じて、第１移動支持部４４、第２移動支持部７４を下降させる。これによって２本の第１移動ローラ３８と２本の第２移動ローラ４０が下方に移動し、アキューム装置１内部に溜め込むウエブＷの量を増加させることができる。この場合に、第１移動支持部４４と第２移動支持部７４の上方は上シャッタ部材６２によって閉塞され、下方は下シャッタ部材６８によって閉塞されている。 Next, when the web W is decelerated or stopped according to the operating state of the winding device on the downstream side, the accumulator device 1 is operated. As shown in FIG. 2, the first moving support portion 44 and the second moving support portion 74 are lowered according to the traveling speed of the web W to be decelerated or stopped. As a result, the two first moving rollers 38 and the two second moving rollers 40 move downward, and the amount of web W stored inside the accumulator 1 can be increased. In this case, the upper part of the first moving support portion 44 and the second moving support portion 74 is closed by the upper shutter member 62, and the lower part is closed by the lower shutter member 68.

次に、下流側の巻取り装置などの作業が終了し、ウエブＷの走行速度を再び通常速度に上昇させる場合には、図１に示すように、第１移動支持部４４、第２移動支持部７４を上昇させることにより、２本の第１移動ローラ３８、２本の第２移動ローラ４０を上昇させて、作業空間１０２内部に滞留させるウエブＷを少なくする。 Next, when the work of the winding device on the downstream side is completed and the traveling speed of the web W is increased to the normal speed again, as shown in FIG. 1, the first moving support portion 44 and the second moving support By raising the portion 74, the two first moving rollers 38 and the two second moving rollers 40 are raised to reduce the web W staying inside the work space 102.

（３）効果
本実施形態によれば、第１固定ローラ３２、第２固定ローラ３４、第３固定ローラ３６、第１移動ローラ３８、第２移動ローラ４０が一方の軸のみ支持された片持ちであるため、基台１２の左右方向の寸法を小さくすることができ、アキューム装置１のフレーム１０の設置空間を削減できる。 (3) Effect According to the present embodiment, the first fixed roller 32, the second fixed roller 34, the third fixed roller 36, the first moving roller 38, and the second moving roller 40 are cantilevered with only one shaft supported. Therefore, the dimension of the base 12 in the left-right direction can be reduced, and the installation space of the frame 10 of the accumulator 1 can be reduced.

また、各ローラが片持ちであるため、ウエブＷを通す場合に右側から簡単に通紙することができ、そのため通紙作業が容易となる。 Further, since each roller is cantilevered, it is possible to easily pass the paper from the right side when passing the web W, which facilitates the paper passing work.

また、上下動に移動する２本の第１移動ローラ３８を支持する第１移動支持部４４は、第１雄ネジ棒５０と２本のシャフト５４，５６によって片持ち状態を支持しているため、第１移動ローラ３８にウエブＷが架け渡されても、第１移動ローラ３８の回転軸が撓んだりすることがない。第２移動ローラ４０についても同様に回転軸が水平方向から撓んだりすることがない。 Further, since the first moving support portion 44 that supports the two first moving rollers 38 that move up and down is supported in the cantilever state by the first male screw rod 50 and the two shafts 54 and 56. Even if the web W is bridged over the first moving roller 38, the rotation shaft of the first moving roller 38 does not bend. Similarly, the rotation axis of the second moving roller 40 does not bend from the horizontal direction.

また、第１移動ローラ３８、第２移動ローラ４０が上下動しても、第１切欠き部４２と第２切欠き部７２は上シャッタ部材６２，９２と下シャッタ部材６８，９８によって閉塞されているため、作業空間１０２は、第１雄ネジ棒５０、第２雄ネジ棒８０がある空間と隔離されている。したがって、第１雄ネジ棒５０、第２雄ネジ棒８０が回転することによる塵が発生しても、この塵は支持壁３０、上シャッタ部材６２，９２と下シャッタ部材６８，９８によって遮られ、作業空間１０２のクリーン状態を維持できる。 Further, even if the first moving roller 38 and the second moving roller 40 move up and down, the first notch portion 42 and the second notch portion 72 are closed by the upper shutter members 62, 92 and the lower shutter members 68, 98. Therefore, the work space 102 is isolated from the space where the first male screw rod 50 and the second male screw rod 80 are located. Therefore, even if dust is generated by the rotation of the first male screw rod 50 and the second male screw rod 80, the dust is blocked by the support wall 30, the upper shutter members 62, 92, and the lower shutter members 68, 98. , The clean state of the work space 102 can be maintained.

また、作業者は、扉２８の透明板２９から、片持ち状態の各ローラを移動するウエブＷを観察できる。 Further, the operator can observe the web W moving each roller in the cantilever state from the transparent plate 29 of the door 28.
