Description

本発明は、梱包時の緩衝材等として用いられる気泡シート等の複合シート、及びその製造方法に関する。   The present invention relates to a composite sheet such as a bubble sheet used as a cushioning material at the time of packaging, and a method for manufacturing the same.

従来、この種の複合シートとして、バックフィルムと称される平面状をなす平面フィルムと、この平面フィルムに重ね合わせて接合されたキャップフィルムと称される立体構造をなす立体フィルムとを備えたものが知られている（例えば、特許文献１を参照）。   Conventionally, as this type of composite sheet, a flat film called a flat film called a back film and a three-dimensional film called a cap film joined to the flat film in a three-dimensional structure Is known (see, for example, Patent Document 1).

ところで、一定寸法に裁断したこの種の複合シートは、連続複合シートを適宜切断して作られるが、その切断の際に発生するキリコ（切り粉）の処理に手間がかかるという問題がある。すなわち、この種のキリコは薄いフィルムの破片であるため、静電気等により梱包対象物に付着する傾向がある。そのため、このような複合シートを梱包に用いた場合、そのキリコが梱包対象物に悪影響を及ぼすことがあり、キリコを完全に除去することが強く要請されている。この要請に応えるため、バキューム等によりキリコを除去する装置が種々開発されているが、完全にキリコを取り除くことは難しく、何らかの対策が望まれている。   By the way, this type of composite sheet cut to a certain size is made by appropriately cutting a continuous composite sheet, but there is a problem in that it takes time to process the chips (chips) generated during the cutting. That is, since this type of silicon is a thin film fragment, it tends to adhere to the packaging object due to static electricity or the like. Therefore, when such a composite sheet is used for packing, the metal may adversely affect the object to be packed, and it is strongly requested to completely remove the metal. In order to meet this demand, various devices have been developed to remove the dust by vacuum or the like, but it is difficult to completely remove the dust, and some countermeasure is desired.

本発明者らは、このような事情に着目し、キリコを取り除くという発想を大きく転換させ、キリコが発生する根本原因を究明すべく種々の研究を行った。その結果、フィルムの二度切り現象が生じていることを発見し、これがキリコを発生させる要因となっていることがわかった。   The present inventors paid attention to such a situation, and changed the idea of removing the silico, and conducted various studies to find out the root cause of the occurrence of the silico. As a result, it was discovered that a double-cutting phenomenon of the film occurred, and this was found to be a factor causing the occurrence of chirico.

すなわち、従来、連続複合シートＰＳを切断する際には、図８及び図９に示すように、受け面の端に段差を設けておき、この段部端面と刃Ｐ９とによって連続複合シートＰＳを剪断するように切断していた。ところが、このような方法で切断を行うと、図８に示すように、刃Ｐ９が連続複合シートＰＳの上面に入刀された直後に、その力によって連続複合シートＰＳが段差に沿って下方に屈曲することになる。そのため、図９に示すように、さらに刃Ｐ９が下方に移動すると、気泡を含んだ立体フィルムＰ１２が変形した状態で再度その立体フィルムＰ１２を切断することがあり、二度切断して切り離された立体フィルムＰ１２の小片が前記キリコＰ１５となる、ということが明らかになった。   That is, conventionally, when cutting the continuous composite sheet PS, as shown in FIGS. 8 and 9, a step is provided at the end of the receiving surface, and the continuous composite sheet PS is formed by the step end face and the blade P9. It was cut to shear. However, when cutting is performed by such a method, as shown in FIG. 8, immediately after the blade P9 is inserted into the upper surface of the continuous composite sheet PS, the continuous composite sheet PS is moved downward along the step by the force. It will be bent. Therefore, as shown in FIG. 9, when the blade P9 is further moved downward, the three-dimensional film P12 containing bubbles may be cut again in a state where the three-dimensional film P12 containing air bubbles is deformed, and is cut and cut twice. It became clear that the small piece of the three-dimensional film P12 became the above-mentioned Chirico P15.

本発明者らは、かかる究明結果に基づいて、二度切りが生じないような方法を種々試行し、本発明を完成させるに至った。そして、本発明の方法によれば、キリコが生じないだけでなく、従来の図１０に示すような複合シートＰ１に比べてその切断端面の見栄えが良好な複合シートが得られることもわかった。   Based on the results of the investigation, the present inventors have tried various methods that do not cause double cutting and have completed the present invention. It was also found that according to the method of the present invention, a composite sheet is obtained that not only has no sharpening, but also has a cut end face that looks better than the conventional composite sheet P1 shown in FIG.

特開２００４−２３１２６８号公報JP 2004-231268 A

本発明は、かかる究明結果に基づいて、切断端面の見栄えが良い複合シート、及びキリコが生じない複合シートの製造方法を提供することを目的としている。   An object of the present invention is to provide a composite sheet with a good appearance of the cut end face and a method for producing a composite sheet that does not cause metal chips based on the results of such investigation.

本発明は、以上のような課題を解決するために、次のような構成を採用したものである。すなわち、本発明に係る複合シートは、平面状をなす平面フィルムと、この平面フィルムに重ね合わせて接合された立体構造をなす立体フィルムとを備え、この立体フィルムが、前記平面フィルムと略垂直な切断端面を備えていることを特徴とする。   The present invention employs the following configuration in order to solve the above-described problems. That is, the composite sheet according to the present invention includes a planar film having a planar shape and a three-dimensional film having a three-dimensional structure superimposed and joined to the planar film, and the three-dimensional film is substantially perpendicular to the planar film. A cut end face is provided.

このようなものであれば、切断端面が綺麗に形成されているので、見栄えを良いものとすることができる。   If it is such, since the cut end face is beautifully formed, the appearance can be improved.

平面状をなす平面フィルムと、この平面フィルムに重ね合わせて接合された立体構造をなす立体フィルムとを備えた連続複合シートを切断して前記複合シートを製造する方法の好適な一態様としては、前記連続複合シートの切断すべき箇所を刃に対応する切断位置に配置するとともに、前記切断位置の両側において連続複合シートを保持し、その保持状態を維持しつつ平面フィルムと直交する方向から前記刃を入れて前記連続複合シートの切断すべき箇所を切断するものが考えられる。   As a preferred embodiment of the method for producing a composite sheet by cutting a continuous composite sheet comprising a planar film having a planar shape and a three-dimensional film having a three-dimensional structure superimposed and bonded to the planar film, The portion to be cut of the continuous composite sheet is disposed at a cutting position corresponding to the blade, the continuous composite sheet is held on both sides of the cutting position, and the blade is viewed from a direction perpendicular to the plane film while maintaining the holding state. It is possible to cut the portion of the continuous composite sheet that is to be cut.

このようなものであれば、連続複合シートの立体フィルムを二度切りしてしまうことを防ぐことができ、従来問題となっていたキリコの発生を防ぐことができる。そのため、このような方法によって作られた複合シートは、従来種々試行した手間のかかるキリコの取り除き作業が不要となるだけでなく、この複合シートを梱包時の緩衝材として用いる場合であっても、梱包対象物にキリコが付着するおそれもなくなる。   If it is such, it can prevent cutting the solid film of a continuous composite sheet twice, and can prevent generation | occurrence | production of the metal which became a problem conventionally. Therefore, the composite sheet made by such a method not only eliminates the need for labor-intensive removal of the dust that has been conventionally tried, but even when this composite sheet is used as a cushioning material at the time of packaging, There is no risk of dust sticking to the packing object.

なお、刃は、連続複合シートに対して接離する方向に直線移動することによって連続複合シートを切断するものや、回転しながら連続複合シートを切断するものであってもよい。   The blade may be one that cuts the continuous composite sheet by linearly moving in the direction of contact with or separating from the continuous composite sheet, or one that cuts the continuous composite sheet while rotating.

前記切断位置の両側に受け面をそれぞれ設けておけば、前記連続複合シートを前記受け面にそれぞれ押し付けた状態で保持することができる。   If a receiving surface is provided on each side of the cutting position, the continuous composite sheet can be held in a state of being pressed against the receiving surface.

前記受け面に対向する位置に押圧体を配しておけば、前記連続複合シートを前記押圧体によって前記受け面に押し付けた状態で保持することができる。   If a pressing body is arranged at a position facing the receiving surface, the continuous composite sheet can be held in a state of being pressed against the receiving surface by the pressing body.

前記立体フィルムの好適な一例としては、前記平面フィルムと協働して多数の独立した気泡を形成する立体形状をなしているものが考えられる。   As a preferable example of the three-dimensional film, one having a three-dimensional shape that forms a large number of independent bubbles in cooperation with the planar film can be considered.

本発明は、以上のような構成であるから、切断端面の見栄えが良い複合シート、及びキリコが生じない複合シートの製造方法を提供することができる。   Since this invention is the structure as mentioned above, the manufacturing method of the composite sheet with which the appearance of a cutting | disconnection end surface is good, and the composite sheet which does not produce a chirico can be provided.

以下、本発明の一実施形態について図面を参照して説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

この複合シート１は、例えば、梱包時の緩衝材等として用いられるものであり、図１ないし図７に示すように、連続複合シートＳを切断装置２を用いて一定寸法に適宜切断して作られるものである。具体的には、この複合シート１は、図１及び図２に示すように、バックフィルムと称される平面状をなす平面フィルム１１と、この平面フィルム１１に重ね合わせて接合されたキャップフィルムと称される立体構造をなす立体フィルム１２とを備えたものであり、この立体フィルム１２が、前記平面フィルム１１と略垂直な切断端面１４を備えている。前記立体フィルム１２は、前記平面フィルム１１と協働して多数の独立した気泡１３を形成する立体形状をなしている。   The composite sheet 1 is used, for example, as a cushioning material at the time of packing. As shown in FIGS. 1 to 7, the continuous composite sheet S is appropriately cut using a cutting device 2 to a certain size. It is what Specifically, as shown in FIGS. 1 and 2, the composite sheet 1 includes a planar film 11 having a planar shape called a back film, and a cap film superposed and bonded to the planar film 11. The three-dimensional film 12 has a three-dimensional structure called a three-dimensional structure, and the three-dimensional film 12 has a cut end surface 14 that is substantially perpendicular to the flat film 11. The three-dimensional film 12 has a three-dimensional shape that forms a large number of independent bubbles 13 in cooperation with the planar film 11.

本実施形態においては、シート状の素材として、例えば、図１及び図２に示すように、多数の気泡形成用突起を有してなるキャップフィルムと、このキャップフィルムの突起開放側に添着したバックフィルムとからなる２層構造を有する気泡シートを用いている。この気泡シートは、キャップフィルム及びバックフィルムからなる２層構造を有する従来品と同様であり、材料としては、常用のポリエチレンをはじめ、ポリプロピレンのようなポリオレフィン、エチレン−酢酸ビニル共重合体、ナイロンその他種々のプラスチックが使用できる。   In this embodiment, as a sheet-like material, for example, as shown in FIGS. 1 and 2, a cap film having a large number of bubble forming protrusions and a back attached to the protrusion open side of the cap film. A bubble sheet having a two-layer structure made of a film is used. This air bubble sheet is the same as the conventional product having a two-layer structure consisting of a cap film and a back film, and the materials include polyolefins such as polypropylene, ethylene-vinyl acetate copolymer, nylon, etc. Various plastics can be used.

この複合シート１を製造する切断装置２は、図３ないし図７に示すように、一定の幅寸法を有する長尺な連続複合シートＳを受け台６上に送るとともに、その連続複合シートＳの切断すべき箇所Ｓ１が前記受け台６上に設定された切断位置２１に達した段階でその送り動作を停止させるための送り機構３と、この送り機構３により送られて停止した連続複合シートＳを受け台６上に保持するための保持機構４と、この保持機構４により保持された連続複合シートＳを前記切断位置２１において切断するための切断機構５とを備えている。   As shown in FIGS. 3 to 7, the cutting device 2 that manufactures the composite sheet 1 sends a long continuous composite sheet S having a certain width dimension onto a receiving base 6, and The feed mechanism 3 for stopping the feeding operation when the part S1 to be cut reaches the cutting position 21 set on the receiving tray 6, and the continuous composite sheet S sent and stopped by the feed mechanism 3 A holding mechanism 4 for holding on the cradle 6 and a cutting mechanism 5 for cutting the continuous composite sheet S held by the holding mechanism 4 at the cutting position 21 are provided.

前記送り機構３は、図３ないし図７に示すように、連続複合シートＳを挟持して長手方向に搬送する送りローラ７などを主体に構成した通常のものである。   As shown in FIGS. 3 to 7, the feed mechanism 3 is a normal one mainly composed of a feed roller 7 that sandwiches the continuous composite sheet S and transports it in the longitudinal direction.

前記保持機構４は、図３ないし図７に示すように、前記受け台６における切断位置２１の両側に設けられた対をなす受け面６１と、これら受け面６１に対向する位置にそれぞれ配された押圧体８とを主体に構成されたものである。この保持機構４は、前記連続複合シートＳが停止した際に、前記押圧体８を降下させて前記連続複合シートＳを前記受け面６１に押し付けた状態で保持するものである。本実施形態では、保持機構４を切断機構５の近傍に配置している。押圧体８の昇降には、種々のアクチュエータを使用することが可能である。受け面６１は、前記連続複合シートＳを水平に案内することができる平滑な水平面であり、前記切断位置２１を挟んで上流側及び下流側にそれぞれ設けられている。   As shown in FIGS. 3 to 7, the holding mechanism 4 is disposed at a pair of receiving surfaces 61 provided on both sides of the cutting position 21 in the receiving table 6 and at positions facing these receiving surfaces 61. The pressing body 8 is mainly configured. When the continuous composite sheet S stops, the holding mechanism 4 lowers the pressing body 8 and holds the continuous composite sheet S pressed against the receiving surface 61. In the present embodiment, the holding mechanism 4 is disposed in the vicinity of the cutting mechanism 5. Various actuators can be used for raising and lowering the pressing body 8. The receiving surface 61 is a smooth horizontal surface that can horizontally guide the continuous composite sheet S, and is provided on the upstream side and the downstream side of the cutting position 21, respectively.

前記切断機構５は、図３ないし図７に示すように、前記受け台６の切断位置２１に対応する部位に設けられた刃進入部６２と、この刃進入部６２の上方に配設された刃９とを主体に構成されたもので、刃先９１が刃進入部６２に進入するまで降下するようになっている。刃９の昇降には、種々のアクチュエータを使用することが可能である。刃９は、下縁に刃先９１を有する平板状のもので、水平姿勢を維持しつつ、平面フィルム１１に対して垂直に降下し得るようになっている。   As shown in FIGS. 3 to 7, the cutting mechanism 5 is disposed above the blade entry portion 62 and a blade entry portion 62 provided at a portion corresponding to the cutting position 21 of the cradle 6. The blade 9 is configured mainly, and is lowered until the blade edge 91 enters the blade entry portion 62. Various actuators can be used to raise and lower the blade 9. The blade 9 is a flat plate having a blade edge 91 at the lower edge, and can be lowered vertically with respect to the flat film 11 while maintaining a horizontal posture.

次に、図面を参照しながら、この切断装置２を用いて前記連続複合シートＳの切断すべき箇所Ｓ１を切断して前記切断端面１４を有した複合シート１を得る手順を説明する。   Next, a procedure for obtaining the composite sheet 1 having the cut end face 14 by cutting the portion S1 to be cut of the continuous composite sheet S using the cutting device 2 will be described with reference to the drawings.

まず、図３に示すように、前記送り機構３により送られてくる前記連続複合シートＳが所定箇所で停止し、その連続複合シートＳの切断すべき箇所Ｓ１が刃９に対応する切断位置２１に配置される。   First, as shown in FIG. 3, the continuous composite sheet S sent by the feed mechanism 3 stops at a predetermined location, and the cutting position 21 where the continuous composite sheet S is to be cut corresponds to the blade 9. Placed in.

次いで、図４に示すように、前記押圧体８が降下し、前記切断位置２１の両側において連続複合シートＳが保持される。すなわち、前記連続複合シートＳの切断すべき箇所Ｓ１の前後の部位が、押圧体８によってそれぞれ受け台６の受け面６１に押し付けられ、保持される。   Next, as shown in FIG. 4, the pressing body 8 is lowered, and the continuous composite sheet S is held on both sides of the cutting position 21. That is, the front and rear portions of the continuous composite sheet S to be cut are pressed and held by the pressing body 8 against the receiving surface 61 of the receiving base 6.

その保持状態で、図５に示すように、前記刃９が降下し、図６に示すように、平面フィルム１１と直交する方向から前記連続複合シートＳの切断すべき箇所Ｓ１が切断される。そして、切断された複合シート１は、図７に示すように、シート受け２２上に順次積み重ねられる。なお、切断位置の下流側にも送り機構を設けて切断された複合シートを送りローラによって送るようにしてもよい。   In the holding state, the blade 9 is lowered as shown in FIG. 5, and the portion S1 of the continuous composite sheet S to be cut is cut from the direction orthogonal to the flat film 11 as shown in FIG. Then, the cut composite sheets 1 are sequentially stacked on the sheet receiver 22 as shown in FIG. A composite sheet that has been cut by providing a feed mechanism on the downstream side of the cutting position may be fed by a feed roller.

以上の動作を繰り返すことによって、一定寸法の複合シート１が順次製造される。この複合シート１の搬送方向の両端に露出する切断端面１４は、図１及び図２に示すように、立体フィルム１２が、前記平面フィルム１１と略垂直に切り取られた形状となっている。   By repeating the above operations, composite sheets 1 having a certain size are sequentially manufactured. As shown in FIGS. 1 and 2, the cut end surfaces 14 exposed at both ends in the conveyance direction of the composite sheet 1 have a shape in which the three-dimensional film 12 is cut substantially perpendicularly to the flat film 11.

以上に述べたように、本実施形態に係る複合シート１は、平面状をなす平面フィルム１１と、この平面フィルム１１に重ね合わせて接合された立体構造をなす立体フィルム１２とを備え、この立体フィルム１２が、前記平面フィルム１１と略垂直な切断端面１４を備えているので、従来の二度切りが行われていたものに比べてその切断端面１４の見栄えを良好にすることができる。   As described above, the composite sheet 1 according to this embodiment includes the planar film 11 having a planar shape, and the three-dimensional film 12 having a three-dimensional structure that is overlapped and joined to the planar film 11. Since the film 12 includes the cut end face 14 that is substantially perpendicular to the flat film 11, the appearance of the cut end face 14 can be improved as compared with the conventional one that has been cut twice.

また、前記連続複合シートＳの切断すべき箇所Ｓ１を刃９に対応する切断位置２１に配置するとともに、前記切断位置２１の両側において連続複合シートＳを保持し、その保持状態を維持しつつ平面フィルム１１と直交する方向から前記刃９を入れて前記連続複合シートＳの切断すべき箇所Ｓ１を切断して前記切断端面１４を有した複合シート１を得るようにしているので、切断時における立体フィルム１２の二度切りの発生及びキリコの発生を防止することができる。すなわち、従来の方法によれば、例えば１２００ｍｍ幅の連続気泡シートから２８０ｍｍ×２８０ｍｍのカットシートを切り出す場合、長辺サイズ５ｍｍ以上のキリコの発生は１０００枚当り約４０片であるとの調査結果を得ていたが、本実施形態によれば、幅３００ｍｍの連続気泡シートを２００回切断した場合であってもキリコは全く発生しなかった。   Further, the portion S1 to be cut of the continuous composite sheet S is disposed at the cutting position 21 corresponding to the blade 9, the continuous composite sheet S is held on both sides of the cutting position 21, and the plane is maintained while maintaining the holding state. Since the blade 9 is inserted from the direction orthogonal to the film 11 to cut the portion S1 to be cut of the continuous composite sheet S to obtain the composite sheet 1 having the cut end face 14, the three-dimensional shape at the time of cutting is obtained. It is possible to prevent the film 12 from being cut twice and the occurrence of dust. That is, according to the conventional method, for example, when a cut sheet of 280 mm × 280 mm is cut out from an open cell sheet having a width of 1200 mm, the investigation result indicates that the occurrence of silicon having a long side size of 5 mm or more is about 40 pieces per 1000 sheets. However, according to the present embodiment, no silicon was generated even when a 300-mm wide open-cell sheet was cut 200 times.

特に、前記立体フィルム１２が、前記平面フィルム１１と協働して多数の独立した気泡１３を形成する立体形状をなしている２層の気泡シートの場合、多数の気泡１３が形成されているので、各箇所で二度切りが行われるとキリコが大量に発生することになるが、本実施形態の複合シート１は、前述したような方法で切断されているので、キリコを発生させることなく製品とすることができる。また、本実施形態に示したように、気泡１３が平面視一直線上に並ぶ連続複合シートＳの巾方向に沿って切断する場合には、気泡１３が千鳥状に並ぶ流れ方向に沿って切断する場合に比べて、その効果がより明確になる。なお、気泡シートの流れ方向とは、巾方向に対して直角方向に延びる長手方向のことを指し、この方向は巾方向に比べて、引き裂きにくいという性質を有する。   In particular, in the case where the three-dimensional film 12 is a two-layered bubble sheet having a three-dimensional shape that forms a large number of independent bubbles 13 in cooperation with the flat film 11, a large number of bubbles 13 are formed. In addition, when the cutting is performed twice at each location, a large amount of silicon is generated. However, since the composite sheet 1 of the present embodiment is cut by the method as described above, the product is generated without generating metal. It can be. Further, as shown in the present embodiment, when the bubbles 13 are cut along the width direction of the continuous composite sheet S arranged in a straight line in plan view, the bubbles 13 are cut along the flow direction where the bubbles 13 are arranged in a staggered manner. Compared to the case, the effect becomes clearer. The flow direction of the bubble sheet refers to a longitudinal direction extending in a direction perpendicular to the width direction, and this direction has a property that it is difficult to tear compared to the width direction.

また、前記切断位置２１の両側に受け面６１をそれぞれ設けておき、前記連続複合シートＳを前記受け面６１にそれぞれ押し付けた状態で保持するので、受け面６１側に配される立体フィルム１２の頂点部分を平らな状態に保つことができるとともに、平面フィルム１１の上方から刃９によって力が加わった場合にも、両側で押さえ付けられているため、平面フィルム１１及び立体フィルム１２が変形することを防止または抑制することができる。   Further, since receiving surfaces 61 are provided on both sides of the cutting position 21 and the continuous composite sheet S is held in a state of being pressed against the receiving surface 61, the three-dimensional film 12 disposed on the receiving surface 61 side. The top portion can be kept flat, and even when a force is applied by the blade 9 from above the flat film 11, the flat film 11 and the three-dimensional film 12 are deformed because they are pressed on both sides. Can be prevented or suppressed.

特に、本実施形態においては、前記受け面６１に対向する位置に押圧体８を配しておき、前記連続複合シートＳを前記押圧体８によって前記受け面６１に押し付けた状態で保持するので、立体フィルム１２側は平らな受け面６１に保持され、平面フィルム１１側も平らな押圧体８の下面に保持され、切断時に連続複合シートＳを所望の姿勢に維持することができる。   In particular, in the present embodiment, the pressing body 8 is disposed at a position facing the receiving surface 61, and the continuous composite sheet S is held in a state of being pressed against the receiving surface 61 by the pressing body 8. The three-dimensional film 12 side is held by the flat receiving surface 61, and the flat film 11 side is also held by the lower surface of the flat pressing body 8, and the continuous composite sheet S can be maintained in a desired posture at the time of cutting.

さらに、保持機構４を切断機構５の近傍に配置しているので、刃先９１が連続複合シートＳに当接する際における連続複合シートＳの切断すべき箇所Ｓ１の変形を可及的に防ぐことができ、連続複合シートＳに対して垂直に切断することができる。   Furthermore, since the holding mechanism 4 is disposed in the vicinity of the cutting mechanism 5, it is possible to prevent as much as possible the deformation of the portion S1 to be cut of the continuous composite sheet S when the cutting edge 91 contacts the continuous composite sheet S. And can be cut perpendicular to the continuous composite sheet S.

なお、本発明は以上に述べた実施形態に限られない。   The present invention is not limited to the embodiment described above.

例えば、複合シートは、上述した気泡シートに限られず、気泡を有しない合成樹脂シートや、合成樹脂製以外のシートも含まれる。気泡を有しない合成樹脂シートの具体的な一例としては、ポリエチレンやポリプロピレン等の樹脂によって作られる２枚のシート（本発明の平面フィルムに相当）と、これらのシートを連結して平行に走る多数のリブ（本発明の立体フィルムに相当）とからなるいわゆるプラスチック段ボール等が挙げられる。また、気泡シートにあっても、２層構造のもの以外にも、前記キャップフィルムの突起先端側に添着したライナーフィルムをさらに有したいわゆる３層構造のものであってもよい。   For example, the composite sheet is not limited to the above-described bubble sheet, and includes a synthetic resin sheet having no bubbles and a sheet other than a synthetic resin sheet. As a specific example of the synthetic resin sheet having no air bubbles, two sheets (corresponding to the flat film of the present invention) made of a resin such as polyethylene or polypropylene, and a large number of these sheets connected in parallel are run. And so-called plastic corrugated cardboard and the like. In addition to the two-layer structure, the bubble sheet may have a so-called three-layer structure that further includes a liner film attached to the protrusion tip side of the cap film.

切断装置の送り機構は、必須の構成要素ではなく、連続複合シートの切断すべき箇所を手動で切断位置に配したり、切断後の複合シートを手動で受け面から取り除くようにしてもよい。   The feed mechanism of the cutting device is not an essential component, and the portion to be cut of the continuous composite sheet may be manually arranged at the cutting position, or the composite sheet after cutting may be manually removed from the receiving surface.

また、前記受け面に対向する位置に押圧体を配する代わりに、例えば、前記受け面に吸引器に連続させた多数の孔を設けておき、前記連続複合シートを前記吸引器によって前記受け面に吸着した状態で保持するようにしてもよい。   Further, instead of arranging a pressing body at a position facing the receiving surface, for example, a number of holes that are connected to a suction device are provided in the receiving surface, and the continuous composite sheet is moved by the suction device to the receiving surface. You may make it hold | maintain in the state adsorb | sucked to.

刃は、上述した実施形態で示したような平行に上下移動するものに限られず、一端側を枢着するとともに他端側を回動させて切断するようなものであってもよい。また、立体フィルムが、前記平面フィルムと略垂直な切断端面を備えるように切断するものであれば、直線状の刃に限られず、曲線状をなす刃や角張った形状の刃であってもよい。   The blade is not limited to one that moves up and down in parallel as shown in the above-described embodiment, but may be one that pivots at one end side and rotates the other end side to cut. Further, as long as the three-dimensional film is cut so as to have a cutting end surface substantially perpendicular to the flat film, the blade is not limited to a straight blade, and may be a curved blade or an angular blade. .

さらに、本実施形態で説明した切断装置２の代わりに、例えば、押圧体と刃を同一のアクチュエータで作動させる等、保持機構による保持動作と切断機構による切断動作とを略同時に行うものであってもよい。   Furthermore, instead of the cutting device 2 described in the present embodiment, for example, the holding operation by the holding mechanism and the cutting operation by the cutting mechanism are performed substantially simultaneously, for example, the pressing body and the blade are operated by the same actuator. Also good.

その他、本発明の趣旨を損ねない範囲で種々に変更してよい。   In addition, various changes may be made without departing from the spirit of the present invention.
