Description
【0001】[0001]
本考案は、所謂ゴミ袋など比較的大型の合成樹脂フィルム製袋状物を製造する さいに使用する曲線切断装置に関する。 The present invention relates to a curve cutting device used for manufacturing a relatively large bag made of a synthetic resin film such as a so-called garbage bag.
【00002】[0002]
従来より、ゴミ袋51などの合成樹脂製袋状物としては、図6に示すように、 袋本体52の口部53を略W字形状に屈曲形成せしめたものが知られており、対 応する突片54を各々縛ることにより簡便に口部53を結束することが出来るも のである。 Conventionally, as a bag made of synthetic resin such as a dust bag 51, a bag body 52 in which a mouth portion 53 of a bag body 52 is formed into a substantially W-shape is known as shown in FIG. The mouth portions 53 can be easily bound by binding the protruding pieces 54 to each other.
【0003】 ところで、かかるゴミ袋51の口部53を略W字形状に屈曲切断する装置とし ては、本考案者等が開示した曲線切断装置(実願平2−75985号)が知られ ており、これを図4及び図5に基いて説明する。 即ち、同図中、55は長尺筒状とされた合成樹脂フィルム製被切断物Aを間欠 的に水平移送せしめるべく所定間隔毎に配設された上下一対の送りロ−ラ、56 は該送りロ−ラ55に連動して昇降作動せしめるべく被切断物Aの移送レベルに 配設されたウエルダ−、57は被切断物Aの移送方向と直交すべく該ウエルダ− 56の前方に配設された直線切断装置で、該直線切断装置57は無端駆動チエ− ン58に所要のカッタ−59が起立保持せしめられた構成よりなる。60は該直 線切断装置57に対応してその前方に水平配設された曲線切断装置で、該曲線切 断装置60は往き側が略W字形状に屈曲された無端駆動チエ−ン61にアタッチ メントを介してカッタ−62が倒起立自在に取付けられた構成よりなるものであ る。By the way, as a device for bending and cutting the mouth portion 53 of the dust bag 51 into a substantially W shape, a curve cutting device disclosed by the present inventors (Japanese Patent Application No. 2-75985) is known. This will be described with reference to FIGS. 4 and 5. That is, in the figure, reference numeral 55 designates a pair of upper and lower feed rollers arranged at a predetermined interval so as to intermittently horizontally transfer the synthetic resin film-shaped workpiece A in the form of a long cylinder, and a pair of feed rollers 56. A welder 57 disposed at the transfer level of the object A to be moved up and down in conjunction with the feed roller 55 is disposed in front of the welder 56 so as to be orthogonal to the transfer direction of the object A. The straight line cutting device 57 has a structure in which a required cutter 59 is erected and held in an endless drive chain 58. Reference numeral 60 denotes a curve cutting device horizontally arranged in front of the straight line cutting device 57. The curve cutting device 60 is attached to an endless drive chain 61 whose forward side is bent in a substantially W shape. The cutter 62 is attached so as to be able to stand upright via the ment.
【0004】 上述の如く構成された従来例は、被切断物Aをシ−ト状に重合した状態で保持 しつつ、送りロ−ラ55を介して所定ピッチ毎に間欠移送せしめる。そして、順 次ウエルダ−56により被切断物Aを所定寸法毎に熱融着せしめたのち、直線切 断装置57と曲線切断装置60を連動して作動せしめ、被切断物Aをその幅方向 に沿って直線状に切断すると共に、略W字形状に屈曲切断し、図6に示すゴミ袋 51を製造するものである。In the conventional example configured as described above, the object A to be cut is held in a sheet-like superposed state, and is intermittently transferred at a predetermined pitch via the feed roller 55. Then, after the object A to be cut is heat-fused to each predetermined size by the sequential welder 56, the linear cutting device 57 and the curve cutting device 60 are operated in conjunction with each other to move the object A in the width direction. Along with the straight line cutting, the waste bag 51 shown in FIG. 6 is manufactured by bending and cutting into a substantially W shape.
【0005】[0005]
ところで、従来の曲線切断装置60は、上述の如く無端駆動チエ−ン61を略 W字形状に屈曲走行せしめつつカッタ−62でもって被切断物Aを屈曲切断せし めるものであるから、その構造が極めて簡単であり、安価に提供することが出来 る反面、無端駆動チエ−ン61がガタ付き、しかも波打ちやすく、ひいては、確 実なる屈曲切断をしずらいのみならず、切断効率や品質的な面において必ずしも 満足し得ないものであった。 By the way, since the conventional curve cutting device 60 bends the endless drive chain 61 into a substantially W-shape as described above and bends and cuts the object A with the cutter 62, While its structure is extremely simple and can be provided at low cost, the endless drive chain 61 is loose and wavy easily, which not only makes it difficult to make a reliable bending cut, but also improves cutting efficiency. It was not always satisfactory in terms of quality.
【0006】 本考案は、従来の問題点を一挙に解決し、合成樹脂フィルムよりなる被切断物 Aを迅速、かつ、確実に効率良く屈曲切断することが出来る便利な曲線切断装置 を提供しようとするものである。The present invention intends to solve the conventional problems all at once, and to provide a convenient curve cutting device that can flexibly cut an object A made of a synthetic resin film quickly and reliably and efficiently. To do.
【0007】[0007]
即ち、本考案は、長尺筒状とされた合成樹脂フィルム製被切断物Aの移送方向 に直交すべくその下方に配設された所要長の横送り機構2と、該横送り機構2上 に直交して取付られた縦送り機構4と、該縦送り機構4上に立設されたカッタ− 用回転ホルダ−5と、カッタ−7を常時切断方向に保持すべく該カッタ−用回転 ホルダ−5を回転制御するカム機構8・10とよりなり、上記カッタ−用回転ホ ルダ−5をカム機構8・10により回転制御せしめつつ横送り機構2及び縦送り 機構4を連動して作動せしめることによりカッタ−7を常時切断方向に向けて略 W字形状に屈曲走行せしめた構成よりなる。 That is, the present invention is directed to a horizontal feed mechanism 2 of a required length, which is arranged below the long-cylindrical synthetic resin film to-be-cut object A so as to be orthogonal to the transfer direction. The vertical feed mechanism 4 mounted orthogonally to the vertical feed mechanism 4, the rotary holder 5 for the cutter standing upright on the vertical feed mechanism 4, and the rotary holder for the cutter for always holding the cutter 7 in the cutting direction. A cam mechanism 8/10 for controlling the rotation of the -5, and the lateral feed mechanism 2 and the vertical feed mechanism 4 are interlocked to operate while controlling the rotation of the cutter rotary holder 5 by the cam mechanism 8/10. As a result, the cutter 7 is always bent in a substantially W shape in the cutting direction.

カッタ−用回転ホルダ−5をカム機構8・10により回転制御せしめつつ、縦 送り機構4により適宜縦送りすると共に、横送り機構2により横送りしてカッタ −7を常時切断方向に向けて略W字形状に屈曲走行せしめ、被切断物Aを屈曲切 断せしめる。 While controlling the rotation of the cutter rotation holder 5 by the cam mechanisms 8 and 10, the vertical feed mechanism 4 appropriately feeds vertically, and the lateral feed mechanism 2 feeds the cutter 7 in the cutting direction at all times. The object A to be cut is bent and cut in a W shape.

以下に、本考案を図面に示す一実施例について説明する。 1は被切断物Aの移送レベルに位置すべくウエルダ−56の前方に配設された 曲線切断装置、2は該曲線切断装置1を構成するロッドレスシリンダで、該ロッ ドレスシリンダ2は被切断物Aの移送方向に対して直交状に水平配設されている 。3は該ロッドレスシリンダ2の負荷を軽減すべくロッドレスシリンダ2に並設 されたリニアモ−タで、該リニアモ−タ3はロッドレスシリンダ2と連動して同 期等速作動することにより直線的な横送りを行うものとされている。4は上記ロ ッドレスシリンダ2及びリニアモ−タ3に直交して縦送り自在に架設されたリニ アモ−タ、5は該リニアモ−タ4の可動子上に軸受部材6を介して上向きに設け られたカッタ−用回転ホルダ−、7は該カッタ−用回転ホルダ−5上に着脱自在 に起立保持された曲線切断用カッタ−、8は前記ロッドレスシリンダ2と対応す べくカッタ−用回転ホルダ−5の上方に配設された下面に略W字形状のカム溝9 を有する板カム、10は該板カム8のカム溝9に沿ってスライドすべくカッタ− 用回転ホルダ−5の上面に配設された一対のカムフォロア−である。11は前記 の曲線切断用カッタ−7より後方に位置せしめるべく取付け支柱12を介してロ ッドレスシリンダ2に立設された直線切断用カッタ−、13は被切断物Aの切断 縁を押圧支持すべく被切断物Aの走行線上に配設された押え板である。 An embodiment of the present invention shown in the drawings will be described below. 1 is a curve cutting device which is arranged in front of the welder 56 so as to be positioned at the transfer level of the object A to be cut. 2 is a rodless cylinder which constitutes the curve cutting device 1. The rodless cylinder 2 is to be cut. It is horizontally arranged in a direction orthogonal to the transfer direction of the object A. 3 is a linear motor installed in parallel with the rodless cylinder 2 in order to reduce the load on the rodless cylinder 2. The linear motor 3 is linearly operated by operating at the same speed in synchronization with the rodless cylinder 2. It is supposed to perform horizontal feed. Reference numeral 4 denotes a linear motor which is vertically installed so as to be orthogonal to the rodless cylinder 2 and the linear motor 3 and is vertically mounted on a mover of the linear motor 4 via a bearing member 6 so as to face upward. The cutter rotary holder, 7 is a cutter for curve cutting which is detachably held upright on the cutter rotary holder 5, and 8 is the cutter rotary holder 5 so as to correspond to the rodless cylinder 2. A plate cam 10 having a substantially W-shaped cam groove 9 on the lower surface thereof is disposed on the upper surface of the cutter rotary holder 5 so as to slide along the cam groove 9 of the plate cam 8. And a pair of cam followers. Reference numeral 11 denotes a linear cutting cutter which is erected on the rodless cylinder 2 through a mounting column 12 so as to be positioned rearward of the curved cutting cutter 7, and 13 serves to press and support the cutting edge of the object A to be cut. It is a holding plate arranged on the traveling line of the object to be cut A.
【0010】 次に、上述の如く構成された実施例の作動について説明する。 まず、ウエルダ−56により所定寸法でもって熱融着した被切断物Aを順次間 欠的に曲線切断装置1上に移送せしめ、その融着部位を押え板13でもって押圧 支持する。しかるのち、ロッドレスシリンダ2・リニアモ−タ3・4を各々連動 して作動せしめる。すると、カッタ−用回転ホルダ−5がカムフォロア−10を 介して板カム8により回転制御されつつリニアモ−タ4により適宜縦送りされる と共に、ロッドレスシリンダ2及びリニアモ−タ3により横送りされ、曲線切断 用カッタ−7は図3に示すように常時切断方向に向けて保持されつつ略W字形状 に屈曲走行して被切断物Aを屈曲切断せしめる。このさい、直線切断用カッタ− 11は、ロッドレスシリンダ2の作動により曲線切断用カッタ−7と同期に直線 走行し、被切断物Aを直線状に切断せしめる。被切断物Aの切断が完了すると、 切断屑は上方に配設された吸引ファン(図示略)により吸引除去されると共に、 押え板12が自動的に外れ、切断形成されたゴミ袋51は折畳み工程など次工程 に移送される。Next, the operation of the embodiment configured as described above will be described. First, an object A to be cut, which is heat-fused with a predetermined size by a welder 56, is intermittently transferred onto the curve cutting device 1, and the fused portion is pressed and supported by a holding plate 13. After that, the rodless cylinder 2 and linear motors 3 and 4 are operated in conjunction with each other. Then, the rotary holder 5 for the cutter is appropriately vertically fed by the linear motor 4 while being rotationally controlled by the plate cam 8 via the cam follower 10, and is also laterally fed by the rodless cylinder 2 and the linear motor 3. As shown in FIG. 3, the curved cutting cutter 7 is held in the cutting direction at all times and bends and runs in a substantially W-shape to bend and cut the object A. At this time, the linear cutting cutter 11 travels linearly in synchronization with the curved cutting cutter 7 by the operation of the rodless cylinder 2, and cuts the object A to be cut linearly. When the cutting of the object to be cut A is completed, the cutting waste is sucked and removed by the suction fan (not shown) provided above, and the pressing plate 12 is automatically detached, and the cut dust bag 51 is folded. It is transferred to the next process such as a process.
【0011】 切断屑が除去されると共にゴミ袋51が次工程に移送されると、再び被切断物 Aが曲線切断装置1上に移送され、ロッドレスシリンダ2・リニアモ−タ3・4 の作動により曲線切断用カッタ−7及び直線切断用カッタ−11が帰り走行を開 始し、被切断物Aを屈曲・直線切断してゴミ袋を形成する。 以下同様に、カッタ−用回転ホルダ−5をカム機構8・10により回転制御せ しめつつ、縦送り機構4により適宜縦送りすると共に、横送り機構2により横送 りして曲線切断用カッタ−7を常時切断方向に向けて略W字形状に屈曲走行せし め、被切断物Aを屈曲切断せしめると共に、これに連動して直線切断用カッタ− 11を直線走行せしめ、順次被切断物Aを切断せしめるとよい。When the cutting waste is removed and the dust bag 51 is transferred to the next step, the object A to be cut is again transferred onto the curved cutting device 1, and the rodless cylinder 2 and the linear motors 3 and 4 are operated. As a result, the curved cutting cutter 7 and the linear cutting cutter 11 start returning and traveling, and the object A to be cut is bent and linearly cut to form a dust bag. Similarly, while the rotation of the cutter rotation holder 5 is controlled by the cam mechanisms 8 and 10, the vertical feed mechanism 4 appropriately vertically feeds it, and the lateral feed mechanism 2 horizontally feeds it to the curved cutting cutter. 7 is always bent in a substantially W-shape toward the cutting direction to bend and cut the object to be cut A, and in parallel with this, the cutter 11 for straight line cutting is linearly moved to sequentially cut the object to be cut A. It is good to let it cut off.
【0012】 なお、上記実施例において、横送り機構としてロッドレスシリンダ2が、縦送 り機構としてリニアモ−タ4が各々示されているが、これに限定されるものでな く、ネジ機構やスライド機構など公知の直線送り機構を採用しても本考案の目的 を達成することが出来るものである。Although the rodless cylinder 2 is shown as the lateral feed mechanism and the linear motor 4 is shown as the vertical feed mechanism in the above embodiments, the present invention is not limited to this, and a screw mechanism or Even if a known linear feed mechanism such as a slide mechanism is adopted, the object of the present invention can be achieved.
【0013】[0013]
本考案は上述のように構成されているから、カッタ−用回転ホルダ−5をカム 機構8・10により回転制御せしめつつ、縦送り機構4により適宜縦送りすると 共に、横送り機構2により横送りしてカッタ−7を常時切断方向に向けて略W字 形状に屈曲走行せしめ、被切断物Aを屈曲切断せしめることが出来るものであっ て、合成樹脂フィルムよりなる被切断物Aの屈曲切断を迅速、かつ、確実に行う ことが出来、ひいては、ゴミ袋51などの合成樹脂製袋状物を極めて効率よく形 成することが出来る。 Since the present invention is constructed as described above, while the rotation of the cutter rotation holder 5 is controlled by the cam mechanisms 8 and 10, the vertical feed mechanism 4 appropriately feeds the vertical movement, and the horizontal feed mechanism 2 also feeds the horizontal feed. Then, the cutter 7 is always bent in a substantially W-shape in the cutting direction so that the object A can be bent and cut, and the object A made of a synthetic resin film can be bent and cut. It can be carried out quickly and reliably, and by extension, a bag made of synthetic resin such as the dust bag 51 can be formed extremely efficiently.
