本考案はウエブ切断装置に関し、より詳しくはウエブ（帯状の長尺包装紙、布 、不織布、プラスチックフィルム等）より矩形、台形、平行四辺形、三角形等の 切断片を切り出すウエブ切断装置に関する。 The present invention relates to a web cutting device, and more specifically to a web cutting device (elongated wrapping paper, cloth, etc.). , non-woven fabric, plastic film, etc.) into rectangular, trapezoidal, parallelogram, triangular, etc. The present invention relates to a web cutting device that cuts out cut pieces.
【０００２】0002
従来、ウエブを切断するにはウエブをコイルホルダから手作業によって巻き戻 して水平台上に拡げ、予め計測し固定したストッパに当接させて定尺とし手作業 でカッタナイフにより切断するか、乃至は図１３に示すような径方向拡縮可能な 羽根６０を有する所謂十字リール７０もしくは類似装置にウエブを必要な長さだ け巻き取り、羽根６０に沿って人力によりカッタナイフ２００を動かせて切断す るかのいずれかの手段が通常用いられていた。 Traditionally, cutting a web involves manually unwinding the web from a coil holder. Then, spread it out on a horizontal table, measure it in advance, make it come into contact with a fixed stopper, and manually measure it to a fixed length. cut with a cutter knife, or as shown in Fig. 13, which can be expanded and contracted radially. A so-called cross-shaped reel 70 or similar device with blades 60 is loaded with the web to the required length. The cutter knife 200 is manually moved along the blade 60 to cut it. Usually one of the following methods was used:
【０００３】 しかし、鉄鋼二次製品等を包装するための大型包装紙は例えば巾２，７００mm ×長さ６，０００mmに達するものも珍しくないので、前記のような手作業は容易 ではなく、しかも紙等のウエブに皺等の欠陥を生じさせずに所定の切断片を得る 事は仲々に困難であった。0003 However, large wrapping paper for packaging secondary steel products, etc. has a width of 2,700 mm, for example. ×It is not uncommon for pieces to reach 6,000mm in length, so manual work like the one above is easy. Moreover, it is possible to obtain a predetermined cut piece without causing defects such as wrinkles in the web such as paper. Things were difficult for Nakamura.
【０００４】 またコイルホルダよりウエブを巻き戻して展開する場合、ウエブを巻き戻すた めに薄鋼帯の如くピンチロールを用いると、上または下ロールにウエブが巻き付 いてしまい処置に困る事があり、その他にもウエブ自体に剛性がないので皺の発 生や切断事故が生じ易いという問題点があった。0004 Also, when unwinding the web from the coil holder and unfolding it, If a pinch roll is used, such as a thin steel strip, the web will wrap around the upper or lower roll. In addition, the web itself has no rigidity, so it may cause wrinkles. There was a problem in that accidents such as cutting and cutting were likely to occur.
【０００５】 そこで本考案者等は鋭意検討の結果、ウエブ前端を把持して引張る方式が特に 薄物ウエブの場合単純にして最も適している事を知り、本考案に到達した。[0005] As a result of intensive study, the inventors of the present invention found a method that grips and pulls the front end of the web. We found that it is simple and most suitable for thin webs, and arrived at the present invention.

【００１４】 門型切断機１０自体は図１，２に示される如く門型フレーム１０Ａと上下クラ ンプ１１，１２、可動ウエブ支持台１６及び門型フレーム１０Ａに沿って包装紙 （ウエブ）の一端外側より反対側外側まで移動するＶ字型カッタ２０及びカッタ ２０を支持するカッタ移動支持台２１を備えている。図示されていないが、カッ タ移動支持台２１は逆転可能なモータ駆動の回転螺子軸によって移動させられる ようになっており、包装紙を横断した処でいずれかの側で停止、待機するように なっている。[0014] The gantry cutting machine 10 itself consists of a gantry frame 10A and upper and lower clamps as shown in FIGS. 1 and 2. Wrapping paper is placed along the pumps 11 and 12, the movable web support stand 16 and the portal frame 10A. V-shaped cutter 20 and cutter that move from the outside of one end of the web to the outside of the opposite side A cutter movable support stand 21 for supporting the cutter 20 is provided. Although not shown, the The data transfer support base 21 is moved by a rotary screw shaft driven by a reversible motor. The vehicle is designed to stop and wait on either side after crossing the wrapping paper. It has become.
【００１５】 カッタ２０は上下クランプ１２の端部と可動ウエブ支持台１６の端部の間の隙 間を巾方向に移動して包装紙帯を切断する。[0015] The cutter 20 is inserted into the gap between the ends of the upper and lower clamps 12 and the ends of the movable web support base 16. The wrapping paper strip is cut by moving in the width direction between the wrapping paper strips.
【００１６】 従ってカッタ２０と可動ウエブ支持台１６とは上下反転させ上向きのカッタが 移動するようにする事も出来る。[0016] Therefore, the cutter 20 and the movable web support 16 are turned upside down so that the cutter faces upward. You can also make it move.

Therefore, it can be moved up and down.
【００１８】 門型切断機１０の前方には包装紙を展開し長さを計測するための水平な展開テ ーブル４３が配置されており、２つの門型フレーム２９，２９の間に包装紙の長 手方向にのびる梁３０Ａ，３０Ａをガイドとして前後に移動するチャック移動支 持台（キャリッジ）３１が設けられている。キャリッジ３１は中央部に門型構造 ３１Ａを持つ下方に開口するチャンネル材であり、その後面にはウエブ把持引張 ユニット３２，３３，３４，３５が配設されており、前面にはこれらの零点位置 調節をするための螺子軸及びそれらの先端部に固着されたハンドル３７，３８， ３９，４０が配置されている。キャリッジ３１の前後方移動は、門型構造３１Ａ がそれに固着された歯付きベルト４２を介してサーボモータ４１によって駆動さ れる事によって行われる。[0018] In front of the portal cutting machine 10, there is a horizontal unfolding table for unfolding the wrapping paper and measuring the length. A long cable 43 is placed between the two gate-shaped frames 29, 29. A chuck movement support that moves back and forth using beams 30A and 30A extending in the hand direction as guides. A carriage 31 is provided. Carriage 31 has a gate-shaped structure in the center It is a downward-opening channel material with a diameter of 31A, and a web gripping tension member is provided on the rear surface. Units 32, 33, 34, and 35 are arranged, and their zero point positions are shown on the front. Screw shafts for adjustment and handles 37, 38 fixed to their tips; 39 and 40 are arranged. The carriage 31 moves forward and backward using the gate-shaped structure 31A. is driven by a servo motor 41 via a toothed belt 42 fixed to it. It is done by being
【００１９】 ウエブ把持引張ユニット３２，３３，３４，３５は門型切断機１０の傾角に応 じて生じた包装紙の斜辺に沿うよう夫々の零点位置調節を行なう。[0019] The web gripping and pulling units 32, 33, 34, 35 are arranged according to the inclination angle of the portal cutting machine 10. Adjust the zero point position so that it is along the oblique side of the wrapping paper.
【００２０】 本考案で最も重要な構成は、上下クランプ１１，１２に、夫々切欠部１１Ａ， １２Ａが、ウエブ把持引張ユニット３２，３３，３４，３５先端部のチャック３ ２Ａ，３３Ａ，３４Ａ，３５Ａとの干渉を避けるために設けられている事である 。[0020] The most important structure of the present invention is that the upper and lower clamps 11 and 12 have notches 11A and 11A, respectively. 12A is the chuck 3 at the tip of the web gripping/pulling unit 32, 33, 34, 35; This is provided to avoid interference with 2A, 33A, 34A, and 35A. .
【００２１】 従来、手動引張り型の切断機でも、切断後のウエブ紙等のウエブ頭出し乃至ウ エブ前端部の把持は最初が極めて困難であった。これが例えば０．２mm厚以上の 剛性の高い鋼帯等の金属帯であれば、ピンチロールによる押し出しで上手くゆく が、薄物の紙、布帛ではこれが極めて困難であった事は前述したとおりである。[0021] Conventionally, even with manual tension type cutting machines, it is difficult to position the web after cutting. It was extremely difficult to grasp the front end of the ebb at first. For example, if the thickness is 0.2 mm or more, If it is a metal strip such as a highly rigid steel strip, extrusion using pinch rolls will work well. However, as mentioned above, this was extremely difficult with thin paper and cloth.
【００２２】 そこで把持チャックの包装紙との接触部に摩擦係数を上げるためエメリーペー パを貼り、充分なストローク（チャック腕長さ、切欠き部懐深さ）で包装紙帯前 端を複数箇所で把持し、引張る事が極めて有効な手段となる。そのために上下ク ランプ切欠部を設けている。[0022] Therefore, in order to increase the coefficient of friction, we applied emery paper to the contact area of the gripping chuck with the wrapping paper. Paste the paper and use a sufficient stroke (length of the chuck arm, depth of the notch) to front the wrapping paper strip. Gripping the end at multiple points and pulling it is an extremely effective method. For this purpose, A lamp cutout is provided.
【００２３】 しかし一方で切欠部ではカッタによる切断時非拘束スパンが長くなる事を避け られないという問題点が生じた。[0023] However, on the other hand, at the notch part, avoid increasing the unrestrained span when cutting with the cutter. The problem arose that it could not be done.
【００２４】 例えばウエブ側端縁部が切欠部にかかるとカッタが巾方向に接触しても上手く 切断開始出来ない事があったので、切欠部にウエブ側端縁部が掛からないように コイルホルダ（アンコイラ）の巾位置を予め調節する手段が採られた。[0024] For example, if the edge of the web side touches the notch, it will not work even if the cutter touches the width direction. There were times when I was unable to start cutting, so I made sure that the edge of the web side did not get caught in the notch. A method was adopted to adjust the width position of the coil holder (uncoiler) in advance.
【００２５】 しかしこれは面倒なだけでなく、必ずしも十分に目的を達する事が出来ない場 合があるため、切欠部１１Ａ，１２Ａをチャックによるウエブ把持時を除いてセ グメントで埋めてやる機構も考えられた。[0025] However, this is not only troublesome, but may not always fully achieve the purpose. Because of this, the notches 11A and 12A should be set aside except when gripping the web with the chuck. A mechanism was also devised to fill the gaps with cement.
【００２６】 これは具体的には可動ウエブ支持台に固着され可動ウエブ支持台上昇時にその 上面が下クランプと面一となる切欠部下クランプと、可動ウエブ支持台上昇時に のみ下降して下クランプとの間でウエブを挟持する切欠部上クランプとを備える 切欠部クランプである。[0026] Specifically, this is fixed to the movable web support and becomes attached when the movable web support is raised. A notched lower clamp whose top surface is flush with the lower clamp, and when the movable web support platform is raised. It is equipped with a notched upper clamp that descends and clamps the web between it and the lower clamp. It is a notch clamp.
【００２７】 ここに図４は切欠部に切欠部クランプを設けない場合の側面断面図、図５は切 欠部上下クランプを設けた場合の側面断面図である。また図５は請求項５の実施 例を示す断面図である。図４，５において１１Ｂ，１２Ｂは夫々切欠部上下クラ ンプであり、１５は切欠部上クランプを昇降させるエアシリンダであり、１６Ａ は可動ウエブ支持台に固着され、切欠部下クランプ１２Ｂを下クランプ１２と面 一に保つ断面Ｌ字状の腕である。カッタ２０を作動させる時、切欠部のウエブス パンを、Ｌ１…切欠部にクランプがない時（図４）、Ｌ２…切欠部にクランプを 設けた時（図５）、とすると、Ｌ１＞Ｌ２となり、Ｌ２は切欠のない部分と同じ 長さとなるから、ウエブ切断上の問題は生じない。但し、このような切欠部クラ ンプを採用するとクランプ、カッタ周辺が複雑になる傾向がある事は否定できな い。FIG. 4 is a side cross-sectional view in the case where no notch clamp is provided in the notch, and FIG. 5 is a side cross-sectional view in the case where upper and lower notch clamps are provided. Further, FIG. 5 is a sectional view showing an embodiment of claim 5. In FIGS. 4 and 5, 11B and 12B are upper and lower notch clamps, 15 is an air cylinder that raises and lowers the upper notch clamp, and 16A is fixed to a movable web support base, and 16A is a cylinder that connects the lower notch clamp 12B to the lower clamp 12. It is an arm with an L-shaped cross section that keeps it flush. When the cutter 20 is operated, the web span at the notch is L 1 when there is no clamp on the notch (Fig. 4), and L 2 when a clamp is provided on the notch (Fig. 5 ). > L2 , and since L2 is the same length as the uncut portion, no problem arises in cutting the web. However, it cannot be denied that if such a notch clamp is adopted, the area around the clamp and cutter tends to become complicated.

Further, 32C and 33C are heads with built-in air cylinders, and 32D and 33D are chuck heads. To adjust the zero point position, the web gripping unit is moved in the longitudinal direction by rotating the threaded shafts 37A, 38A provided with anti-rotation rods 37B, 38B with their handles 37, 38.
【００２９】 以下に本考案実施例の作用について述べる。[0029] The operation of the embodiment of the present invention will be described below.
【００３０】 図１２は本考案実施例のフローチャートである。[0030] FIG. 12 is a flowchart of an embodiment of the present invention.
【００３１】 最初（１）クランプ下降か？カッタ待機位置か？可動ウエブ支持台が下降して いるか？チャック原点か（図６の状態をチャック原点と呼ぶこの時キャリッジ３ １は前進位置にある。）？をチェックし、すべての条件を満足する際に（２）の スタート（図６）となる。すると（３）チャックはＬ３だけ前進して（４）チャ ック閉となり（図７）、包装紙の前端を把持する（この時上下クランプには切欠 部１１Ａ、１２Ａがあるのでチャック３２Ａ，３３Ａとは干渉しない。）ついで （５）上クランプ１１が上昇し、（６）キャリッジ３１が後退する。（図８）そ して予め設定したストッパ（図示せず）までキャリッジ３１が後退する事によっ て（７）位置決めが完了する。First (1) Is the clamp descending? Is the cutter in standby position? Is the movable web support lowered? Is it the chuck origin (the state shown in Fig. 6 is called the chuck origin and the carriage 31 is in the forward position at this time)? When all conditions are satisfied, step (2) starts (Fig. 6). Then (3) the chuck moves forward by L 3 and (4) the chuck closes (Fig. 7) and grips the front end of the wrapping paper (at this time, the upper and lower clamps have notches 11A and 12A, so the chucks 32A and 33A does not interfere.) Next, (5) the upper clamp 11 rises, and (6) the carriage 31 retreats. (FIG. 8) Then, the carriage 31 retreats to a preset stopper (not shown), thereby completing (7) positioning.
【００３２】 セレクトスイッチを予め（８）「全自動」に設定しておくと、（９）再び上ク ランプ１１が下降し、（１０）可動ウエブ支持台が上昇し、（１１）カッタが左 右いずれかの待機位置から巾方向に移動し、包装紙帯を横断して切断する（図９ ）。（１２）切断が終わるとカッタは再び待機位置に入る。（１３）可動ウエブ 支持台が下降する。（１４）チャック開く、しかし包装紙前端が下側チャックに 引掛かって切断片５０Ａが下に落ちない（図１０）。（１５）従ってストローク Ｌ３だけチャックヘッド３２Ｄ，３３Ｄを後退させる。すると切断片５０Ａは落 下し、スタック５０Ｃとなる。 （１６）続いてキャリッジ３１は前進し、（１７）チャック位置は原点に復帰す る。（１８）そしてカウンタ表示枚数が予定枚数に達したか否かチェックし、Ｙ ＥＳならば停止する。ＮＯ（未達）の場合は再び（１）スタートに戻り、作業を 繰り返す。なお、（８）では切断片５０Ａのサイズが展開テーブル４３を超える 場合等の様に手作業計測を行う場合に「半自動」とする。If the select switch is set to (8) "Full automatic" in advance, then (9) the upper clamp 11 will descend again, (10) the movable web support will rise, and (11) the cutter will move to the left or right. From the standby position, move in the width direction and cut across the wrapping paper strip (Figure 9). (12) When cutting is completed, the cutter returns to the standby position. (13) The movable web support is lowered. (14) The zipper opens, but the front end of the wrapping paper gets caught in the lower zipper and the cut piece 50A does not fall down (FIG. 10). (15) Therefore, the chuck heads 32D and 33D are moved back by a stroke L3 . Then, the cut pieces 50A fall and become a stack 50C. (16) Subsequently, the carriage 31 moves forward, and (17) the chuck position returns to the origin. (18) Then, it is checked whether the number of sheets displayed on the counter has reached the scheduled number of sheets, and if YES, the process is stopped. If NO (not achieved), return to (1) start again and repeat the work. Note that (8) is set to "semi-automatic" when manual measurement is performed, such as when the size of the cut piece 50A exceeds the expansion table 43.
【００３３】 「半自動」の場合は（２０）チャックを開き、（２１）チャックを邪魔になら ないよう後退させ、（２２）メジャーを用いて引っ張り出した包装紙５０を折り 曲げまたは丸める等の作業を手作業で行って切断すべき長さを計測し、（２３） 釦を押してカッタを動かし切断する。[0033] In the case of "semi-automatic", open the chuck (20) and (21) move the chuck out of the way. (22) Fold the wrapping paper 50 pulled out using a tape measure. Measure the length to be cut by manually bending or rolling it, and (23) Press the button to move the cutter and cut.
【００３４】 以上の動作をマイコン乃至パソコンを用いたＣＰＵにおいてプログラムに従い 自動的にシークエンスコントロールする。[0034] The above operations are performed according to a program on a CPU using a microcomputer or a personal computer. Automatic sequence control.
【００３５】 なお、図３における傾角θも併せて自動制御する事も勿論可能である。[0035] Note that it is of course possible to automatically control the inclination angle θ in FIG. 3 as well.
【００３６】 この場合には少なくとも門型切断機１０の車輪２５の駆動停止系を電磁ブレー キ付サーボモータ等として自動化する必要がある。[0036] In this case, at least the drive and stop system of the wheels 25 of the portal cutting machine 10 is controlled by an electromagnetic brake. It is necessary to automate it as a servo motor with a key.
【００３７】[0037]
本考案を実施する事により前記目的のすべてが達成される。 By implementing the present invention, all of the above objectives are achieved.
【００３８】 すなわち全体として紙、布等の薄物ウエブに皺や巻き付き、切断、破れ等の欠 陥を生じさせないで帯状のウエブを巻き戻し、正確に矩形、平行四辺形、台形、 三角形等の切断片を得る事が出来る また切欠部があるので（１）チャックがウエブ前端を深くつかむ事が出来る。 （２）チャック開放時にストロークＬ３だけヘッドが後退するので切断片の分離 が良い。（３）半自動では装置の大きさに拘らず長尺の切断片も得られる。等の 効果がある。In other words, it is possible to unwind a belt-shaped web without causing defects such as wrinkles, wrapping, cutting, or tears in the thin web such as paper or cloth as a whole, and accurately cut pieces into rectangular, parallelogram, trapezoidal, triangular, etc. shapes. Also, since there is a notch, (1) the chuck can grip the front end of the web deeply. (2) When the chuck is released, the head moves back by a stroke L3 , so the cut pieces can be easily separated. (3) With semi-automatic operation, long cut pieces can be obtained regardless of the size of the device. There are other effects.
