　一般に、包装用の積層フィルムは、その交換作業の手間を省き、包装作業を中止することなく効率良く行うために、先行する積層フィルムと後行する積層フィルムの端部どうしを相互に連結して、フィルムの長さが１０００ｍ以上にもなるように調整されている。 In general, in order to save the trouble of replacement work and efficiently perform the work without stopping the packaging work, the leading laminated film and the end of the following laminated film are connected to each other. The length of the film is adjusted to 1000 m or more.
　また、包装前の積層フィルムに、印刷不良の部分やラミネート不良の部分等が見つかった場合には、その部分を予め切断除去し、該部分の前後のフィルムを繋ぎ合わせている。そのため、フィルム加工機や充填包装機に供される積層フィルムには、全長の中で数箇所のフィルム連結部が存在することも珍しくはない。 In addition, when a defective printing portion or a defective lamination portion is found in the laminated film before packaging, the portion is cut and removed in advance, and the films before and after the portion are joined together. Therefore, it is not uncommon for a laminated film to be used in a film processing machine or a filling and packaging machine to have several film connecting portions in the entire length.
　このような積層フィルムどうしを連結する方法としては、先行する積層フィルムの尾端部と、後行する積層フィルムの先端部とを突き合わせ、その状態で、これら両フィルムのベースフィルム面にセロハン等からなる粘着テープを貼着し、当該ベースフィルムどうしをフィルム送り方向とは直行する幅方向の全幅にわたって連結する方法がある。
　しかしながら、この連結方法では、たとえば積層フィルムを幅方向で二つ折りにして、それを縦方向および横方向にヒートシールして製袋した場合、その包装袋は、粘着テープの厚みの影響でヒートシールが不十分となり、被包装物が漏れ出すおそれがあるため、フィルムの繋ぎ部分において、充填包装機を一度、停止させて該繋ぎ部分を排除した後、再び生産を開始する方法がとられている。なお、繋ぎ部分の検出方法としては、例えば、先行・後行積層フィルムの繋ぎ目位置にカラーテープを貼着し、このカラーテープの色を検出器等によって読み取ることで繋ぎ部分であることを検出する方法がとられている。 As a method of connecting such laminated films, the tail end portion of the preceding laminated film and the leading end portion of the following laminated film are brought into contact with each other, and in that state, the base film surface of these both films is covered with cellophane or the like. There is a method in which an adhesive tape is attached and the base films are connected over the entire width in the width direction perpendicular to the film feeding direction.
However, in this connection method, for example, when a laminated film is folded in half in the width direction and then heat-sealed in the longitudinal and lateral directions, the packaging bag is heat-sealed due to the influence of the thickness of the adhesive tape. Is not sufficient, and there is a risk of the packaged material leaking out, so in the joint part of the film, the filling and packaging machine is stopped once to remove the joint part and then start production again. . In addition, as a method for detecting the joint portion, for example, a color tape is attached to the joint position of the preceding and following laminated films, and the color of the color tape is read by a detector or the like to detect the joint portion. The way to do it is taken.
　また、特許文献１に開示された方法では、先行する積層フィルムの尾端部と、後行する積層フィルムの先端部とを突き合わせ、該突き合わせ部分のシーラント層側に、両面シール性のラミネートフィルムからなり、少なくとも黒または赤と、黄色とを含む複数色の縞状の印刷層からなる着色中間層を有するストラップフィルムを融着し、該ストラップフィルムを介して先行・後行積層フィルムを相互に連結することが開示されている。このストラップフィルムによれば、先行・後行積層フィルムの端部どうしを、そのシーラント層側への、ストラップフィルムの溶着によって連結できるため、連結強度を向上させることができと共に、ストラップフィルムの着色中間層の色を、検出器（光電式センサ）などを用いて識別することで、繋ぎ部分であることを簡単に検出することができる。 In the method disclosed in Patent Document 1, the tail end portion of the preceding laminated film and the leading end portion of the following laminated film are butted together, and the double-sided sealing laminate film is formed on the sealant layer side of the butted portion. Fusing a strap film having a colored intermediate layer consisting of a plurality of striped printed layers containing at least black or red and yellow, and connecting the preceding and following laminated films to each other via the strap film Is disclosed. According to this strap film, the end portions of the preceding and following laminated films can be connected to each other by welding the strap film to the sealant layer side, so that the connection strength can be improved and the strap film can be colored in the middle. By identifying the color of the layers using a detector (photoelectric sensor) or the like, it is possible to easily detect that the layer is a connected portion.

　しかしながら、上記カラーテープの貼着による方法および特許文献１のいずれの方法も、積層フィルムの表面に施された印刷模様に含まれていない色から、カラーテープや検出するストラップフィルムの色を選定し、その色をセンサによって検出する必要がある。そのため、積層フィルムの印刷が変わるごとに、検出器（光電式センサ）の感度調整を行う必要があり、オペレータの作業負担が増えると共に、感度調整ミスによって繋ぎ部分を正確に検出できないおそれがある。
　また、引用文献１の場合、ストラップフィルムの着色中間層に含まれる赤色や黒色、黄色を、検出器で識別するため、積層フィルムの印刷（色）がストラップフィルムの着色中間層と同系色である場合には、誤検出の可能性が非常に高くなることから、積層フィルムの印刷（色）が制限されてしまうという問題点もあった。 However, both the method by sticking the color tape and the method of Patent Document 1 select the color of the color tape or the strap film to be detected from the colors not included in the printed pattern applied to the surface of the laminated film. The color needs to be detected by a sensor. For this reason, it is necessary to adjust the sensitivity of the detector (photoelectric sensor) each time the printing of the laminated film is changed, which increases the work burden on the operator and may not be able to accurately detect the joint portion due to a sensitivity adjustment error.
Moreover, in the case of the cited document 1, since the red, black, and yellow contained in the colored intermediate layer of the strap film are identified by the detector, the printing (color) of the laminated film is the same color as the colored intermediate layer of the strap film. In such a case, since the possibility of erroneous detection becomes very high, printing (color) of the laminated film is limited.
　そこで、本発明は、従来技術が抱える上記問題点を解決することを課題とするものであり、その目的とするところは、積層フィルムの繋ぎ部分を簡単かつ正確に検出することができ、とくには、積層フィルムの印刷（色）が制限されることのない積層フィルムの連結構造と、そのフィルム繋ぎ部分の検出方法を提案することにある。 Therefore, the present invention has an object to solve the above-mentioned problems of the prior art, and the object is to easily and accurately detect the connecting portion of the laminated film, The present invention proposes a connection structure of laminated films in which printing (color) of the laminated film is not limited, and a method for detecting the film connecting portion.
　上記課題を解決するため、本発明の積層フィルムの連結構造は、少なくともベースフィルム層とシーラント層とを具える先行積層フィルムの尾端部と、少なくともベースフィルム層とシーラント層とを具える後行積層フィルムの先端部とを互いに突き合わせ、該突き合わせ部分に、先行・後行積層フィルムの端部どうしを幅方向の全幅にわたって相互に連結するためのテープを設け、該テープ上またはその近傍の所定の位置に、１次元コードまたは２次元コードを表示したことを特徴とする積層フィルムの連結構造を特徴とする。 In order to solve the above-mentioned problems, the laminated film connection structure of the present invention has a tail end portion of a preceding laminated film including at least a base film layer and a sealant layer, and a subsequent structure including at least the base film layer and the sealant layer. The leading end of the laminated film is abutted against each other, and a tape for connecting the ends of the preceding and succeeding laminated films to each other over the entire width in the width direction is provided at the abutting portion, and a predetermined tape on or near the tape is provided. It is characterized by a laminated film connection structure characterized by displaying a one-dimensional code or a two-dimensional code at a position.

　また、本発明は、少なくともベースフィルム層とシーラント層とを具える、先行積層フィルムと後行積層フィルムとの繋ぎ部分を検出する方法であって、前記先行積層フィルムの尾端部と、後行積層フィルムの先端部とを互いに突き合わせ、該突き合わせ部分にテープを設けて、先行・後行積層フィルムの端部どうしを連結すると共に、前記テープ上またはその近傍の所定の位置に表示された１次元コードまたは２次元コードを検出器によって読み取ることにより、先行積層フィルムと後行積層フィルムとのフィルム繋ぎ部分を特定することを特徴とするフィルム繋ぎ部分の検出方法を特徴とする。 Further, the present invention is a method for detecting a connecting portion between a preceding laminated film and a succeeding laminated film, comprising at least a base film layer and a sealant layer, the tail end portion of the preceding laminated film, and the following One-dimensionally displayed on a predetermined position on or near the tape while abutting each other with the leading end of the laminated film, providing a tape at the abutting portion, connecting the ends of the preceding and following laminated films It is characterized by a method for detecting a film connecting portion, characterized in that a film connecting portion between a preceding laminated film and a succeeding laminated film is specified by reading a code or a two-dimensional code with a detector.

　本発明では、先行・後行積層フィルムの端部どうしを、テープを介して相互に連結し、該テープ上またはその近傍の所定の位置に表示された１次元コードあるいは２次元コードを、例えばコードリーダのような検出器を用いて検出することで、積層フィルムの繋ぎ目位置を簡単かつ正確に特定することができる。 In the present invention, the ends of the preceding and following laminated films are connected to each other via a tape, and a one-dimensional code or a two-dimensional code displayed at a predetermined position on or near the tape is, for example, a code By detecting using a detector such as a reader, the joint position of the laminated film can be easily and accurately specified.
　また、本発明では、１次元コードまたは２次元コードを、検出器によってある特定の配列からなるバーまたはセル（黒色）と、スペースまたはセル（白色）とのコントラスト差（反射光の強弱）を読み取ることで、フィルムの繋ぎ目位置を特定することができる。そのため、積層フィルムに、どのような色や柄の印刷が施されたとしてもフィルムの繋ぎ目位置の検出が可能である。さらに、テープが透明な粘着テープやストラップフィルムからなる場合でも、１次元コードまたは２次元コードをテープ上に遮光性印刷すれば、テープの裏（積層フィルムへの貼着側）から印刷（色）が透けることがないため、該コードをより一層、正確に検出することができる。 Further, in the present invention, the one-dimensional code or the two-dimensional code is read by a detector to detect the contrast difference (the intensity of reflected light) between a bar or cell (black) having a specific arrangement and a space or cell (white). Thus, the joint position of the film can be specified. Therefore, the joint position of the film can be detected no matter what color or pattern is printed on the laminated film. Furthermore, even when the tape is made of a transparent adhesive tape or strap film, if one-dimensional code or two-dimensional code is printed on the tape in a light-shielding manner, it can be printed from the back of the tape (attachment to the laminated film) (color) Since this is not transparent, the code can be detected more accurately.
　したがって、従来のように積層フィルムの印刷（色）毎に、カラーテープを付け替えたり、検出器の感度調整を行う必要がなくなり、作業員の手間を省くことができると共に、誤検出のおそれがない。 Therefore, it is not necessary to change the color tape or adjust the sensitivity of the detector for each printing (color) of the laminated film as in the prior art, so that the labor of the operator can be saved and there is no possibility of erroneous detection. .
　また、テープを両面シール性ラミネートフィルムからなる帯状フィルムとした場合には、該テープの一方のシーラント層を、積層フィルムの繋ぎ目位置のシーラント層と融着接合させることで、先行・後行積層フィルムどうしの連結強度を向上させることができる。これによれば、先行・後行積層フィルムが、多層の厚膜フィルムやアルミニウム箔を積層してなるフィルム等であっても強固に連結することができる。 In addition, when the tape is a belt-shaped film made of a double-sided sealing laminate film, one of the sealant layers of the tape is fused and joined to the sealant layer at the joint position of the laminated film, thereby leading and following lamination. The connection strength between the films can be improved. According to this, even if the preceding / following laminated film is a film formed by laminating a multilayer thick film film or an aluminum foil, it can be firmly connected.

　以下、本発明の実施の形態を図面に基づいて説明する。
　図１および図２は、本発明の積層フィルムの連結構造の一実施形態を示す断面図および平面図であり、先行する積層フィルム１の尾端部と、後行する積層フィルム１’の先端部とが、幅方向に突き合わされた状態で、図１では、繋ぎ目２のシーラント層１ｂ、１ｂ’側に設けたテープ３を介して相互に連結されている。
　テープ３としては、紙、布、金属箔またはフィルムを基材とする粘着テープ４、あるいは両面シール性ラミネートフィルムからなる帯状フィルム５からなることが好ましい。本発明では、テープ３が、前記のいずれにおいても、テープ３上またはその近傍の先行・後行積層フィルム１、１’上の所定の位置（図２ではテープ３上）に１次元または２次元コード１６（以下、単に「コード１６」とも言う。）が表示されていることに特徴がある。
　なお、帯状フィルム５からなるテープ３は、図１に示すように繋ぎ目２のシーラント層１ｂ、１ｂ’側に設けることが好ましい。一方、粘着テープ４からなるテープ３は、繋ぎ目２のベースフィルム層１ａ、１ａ’側に設けてもよく、また、ベースフィルム層１ａ、１ａ’側およびシーラント層１ｂ、１ｂ’側の両方にそれぞれ設けてもよい。
　ここで、上記テープ３近傍の所定の位置とは、先行・後行積層フィルム１、１’の走行方向のテープ３より前方または後方側の、テープ３の両側縁からそれぞれ製品ピッチの半分以内の範囲であることが好ましい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are a cross-sectional view and a plan view showing an embodiment of a laminated film connecting structure according to the present invention, in which a tail end portion of a preceding laminated film 1 and a leading end portion of a following laminated film 1 ′ are shown. Are connected to each other via a tape 3 provided on the side of the sealant layers 1b and 1b ′ of the joint 2 in a state of being butted in the width direction.
The tape 3 is preferably made of a pressure-sensitive adhesive tape 4 based on paper, cloth, metal foil or film, or a belt-like film 5 made of a double-sided sealing laminate film. In the present invention, the tape 3 is one-dimensional or two-dimensional in a predetermined position (on the tape 3 in FIG. 2) on the preceding / following laminated film 1, 1 ′ on or near the tape 3 in any of the above. The code 16 (hereinafter also simply referred to as “code 16”) is displayed.
In addition, it is preferable to provide the tape 3 which consists of the strip | belt-shaped film 5 in the sealant layer 1b, 1b 'side of the joint 2 as shown in FIG. On the other hand, the tape 3 made of the adhesive tape 4 may be provided on the base film layer 1a, 1a ′ side of the joint 2 and also on both the base film layer 1a, 1a ′ side and the sealant layer 1b, 1b ′ side. Each may be provided.
Here, the predetermined position in the vicinity of the tape 3 is within a half of the product pitch from both side edges of the tape 3 on the front or rear side of the tape 3 in the running direction of the preceding and following laminated films 1 and 1 ′. A range is preferable.
　すなわち、本発明では、テープ３上またはその近傍の所定位置に表示された１次元または２次元コード１６の、バーまたはセル（黒色）と、スペースまたはセル（白色）との配列パターンおよびコントラストを、コードリーダ等の検出器によって読み取って繋ぎ目２位置を特定する。これによれば、積層フィルム１、１’の表面側となるベースフィルム層１ａ、１ａ’上に、どのような印刷（色）１ｃ、１ｃ’がされていたとしても、繋ぎ目２の位置を正確に検出することができ、積層フィルム１、１’の印刷（色）１ｃ、１ｃ’が制限されることがないという効果が期待できる。
　また、コード１６を読み取るための検出器に予め、テープ３上に設けられたコード１６のコード規格とコード番号とを指定しておけば、より正確に積層フィルムの継ぎ目２位置を検出することができる。 That is, in the present invention, the arrangement pattern and contrast between the bar or cell (black) and the space or cell (white) of the one-dimensional or two-dimensional code 16 displayed at a predetermined position on or near the tape 3 are expressed as follows: The position of the joint 2 is specified by reading with a detector such as a code reader. According to this, no matter what printing (color) 1c, 1c ′ is made on the base film layers 1a, 1a ′ on the surface side of the laminated films 1, 1 ′, the position of the joint 2 is determined. It can be detected accurately, and the effect that the printing (color) 1c and 1c ′ of the laminated films 1 and 1 ′ is not limited can be expected.
In addition, if the code standard and code number of the code 16 provided on the tape 3 are designated in advance as a detector for reading the code 16, the position of the seam 2 of the laminated film can be detected more accurately. it can.
　なお、１次元または２次元コード１６は、コードリーダ等の検出器によって正確に検出することができれば、テープ３上またはその近傍の先行・後行積層フィルム１、１’上の所定の位置に、どのような方法を用いて表示してもよく、好ましくは、凸版印刷（フレキソ）、凹版印刷（グラビア）、平版印刷（オフセット）等によって印刷形成する。例えば、図３に示すような両面シール性ラミネートフィルムからなる帯状フィルム５からなるテープ３上に１次元または２次元コード１６を設ける場合には、延伸または無延伸ポリエチレンテレフタレートなどの中間層５ｂの片面に１次元コードまたは２次元コード１６を印刷した後、その中間層５ｂを挟むようにしてポリエチレン等からなるシーラント層５ａ、５ｃをラミネートすることにより形成することができる。 In addition, if the one-dimensional or two-dimensional code 16 can be accurately detected by a detector such as a code reader, a predetermined position on the preceding / following laminated film 1, 1 ′ on or near the tape 3 Any method may be used for display, and printing is preferably performed by letterpress printing (flexo), intaglio printing (gravure), planographic printing (offset), or the like. For example, when the one-dimensional or two-dimensional code 16 is provided on the tape 3 made of the belt-like film 5 made of the double-sided sealing laminate film as shown in FIG. 3, one side of the intermediate layer 5b such as stretched or unstretched polyethylene terephthalate After the one-dimensional code or the two-dimensional code 16 is printed, the sealant layers 5a and 5c made of polyethylene or the like are laminated so as to sandwich the intermediate layer 5b.
　さらに、１次元または２次元コード１６を、例えば、黒色（バーまたはセル）、白色（スペースまたはセル）、白色（スペースまたはセル）、遮光性インキの順で凹版印刷（グラビア）、凸版印刷（フレキソ）または平板印刷（オフセット）を行った場合には、テープ３上またはその近傍の所定の位置に遮光性印刷すると、テープ３が、透明な粘着テープ４や図３のような帯状フィルム５からなる場合においても、ベースフィルム層１ａ、１ａ’上の印刷(色) １ｃ、１ｃ’が、該コード１６部分に透き出ることがなく、より一層、正確な検出を行うことができる。 Further, the one-dimensional or two-dimensional code 16 is converted into, for example, black (bar or cell), white (space or cell), white (space or cell), intaglio printing (gravure), letterpress printing (flexo printing) in the order of light-shielding ink. ) Or flat printing (offset), the tape 3 is made of a transparent adhesive tape 4 or a belt-like film 5 as shown in FIG. 3 when light-shielding printing is performed on or at a predetermined position on the tape 3. Even in this case, the print (color) ridges 1c and 1c ′ on the base film layers 1a and 1a ′ do not show through the portion of the code 16, so that more accurate detection can be performed.
　また、１次元または２次元コード１６は、前記したようにテープ３上や、その近傍の先行・後行積層フィルム１、１’上の所定の位置に印刷等する他、図４の平面図に示すように、１次元または２次元コード１６を、例えば、紙やフィルム等を基材とし、一方の面に粘着剤を有する粘着シート１８上に印刷し、該粘着シート１８を、テープ３上や図４にあるようにテープ３近傍位置に貼付することにより表示してもよい。 Further, the one-dimensional or two-dimensional code 16 is printed on a predetermined position on the tape 3 or on the preceding / following laminated films 1 and 1 'in the vicinity thereof as described above, and in the plan view of FIG. As shown, the one-dimensional or two-dimensional code 16 is printed on an adhesive sheet 18 having, for example, paper or film as a base material and having an adhesive on one side, and the adhesive sheet 18 is printed on the tape 3 or As shown in FIG. 4, it may be displayed by sticking to a position near the tape 3.
　なお、先行・後行積層フィルム１、１’は、少なくとも表面となるベースフィルム層１ａ、１ａ’と裏面となるシーラント層１ｂ、１ｂ’とからなり、フィルムの用途や性質などの必要に応じて、ベースフィルム層１ａ、１ａ’とシーラント層１ｂ、１ｂ’との間に各種プラスチックフィルム、アルミニウム箔などの金属箔、紙、各種蒸着層または蒸着フィルム、ポリ塩化ビニリデンコート層その他のコーティング層またはコーティングフィルムなどの中間層を介在させてもよい。 The leading and trailing laminated films 1 and 1 ′ are composed of at least a base film layer 1a and 1a ′ serving as a front surface and a sealant layer 1b and 1b ′ serving as a back surface. Between the base film layers 1a, 1a 'and the sealant layers 1b, 1b', various plastic films, metal foils such as aluminum foil, paper, various deposited layers or deposited films, polyvinylidene chloride coating layers and other coating layers or coatings An intermediate layer such as a film may be interposed.
　ベースフィルム層１ａ、１ａ’としては、二軸延伸ナイロンフィルム層、二軸延伸ポリエチレンテレフタレート層、二軸延伸ポリプロピレンフィルム層、二軸延伸エチレン・ビニルアルコールフィルム層等を用いることが好ましく、シーラント層１ｂ、１ｂ’としては、各種ポリエチレン層、エチレン・酢酸ビニル共重合体層、無延伸ポリプロピレン、エチレン・アクリル酸共重合体層、アイオノマー層などを用いることが好ましい。 As the base film layers 1a and 1a ', it is preferable to use a biaxially stretched nylon film layer, a biaxially stretched polyethylene terephthalate layer, a biaxially stretched polypropylene film layer, a biaxially stretched ethylene / vinyl alcohol film layer, etc., and a sealant layer 1b As 1b ′, it is preferable to use various polyethylene layers, ethylene / vinyl acetate copolymer layers, unstretched polypropylene, ethylene / acrylic acid copolymer layers, ionomer layers, and the like.
　また、現在、多くの商品には、その外装に商品を特定するための１次元コード（バーコード）としてＪＡＮコード（ＪＩＳ化された共通商品コード）が印刷されている。そのため、本発明では、ＪＡＮコード以外のコード規格を使用することで、商品の外装に印刷された１次元コードが誤って読み取られてしまうおそれがなく、安全に検出を行うことができる。したがって、本発明では、使用するコード１６として、ＪＡＮコード以外のコード規格を指定することが好ましく、より安全な検出を行うためには、さらにコード番号を指定することが好ましい。 Currently, many products are printed with a JAN code (JIS common product code) as a one-dimensional code (bar code) for identifying the product on the exterior. Therefore, in the present invention, by using a code standard other than the JAN code, the one-dimensional code printed on the exterior of the product is not erroneously read and can be detected safely. Therefore, in the present invention, it is preferable to specify a code standard other than the JAN code as the code 16 to be used, and it is preferable to further specify a code number in order to perform safer detection.
　なお、図２に示すように、テープ３のフィルム縦幅ｄは、先行積層フィルム１の尾端部と、後行積層フィルム１’の先端部の繋ぎ目２を完全に覆うことができればよく、好ましくは３０ｍｍ以下、より好ましくは５～１０ｍｍとする。 In addition, as shown in FIG. 2, the film length d of the tape 3 is only required to completely cover the joint 2 between the tail end portion of the preceding laminated film 1 and the tip portion of the following laminated film 1 ′. The thickness is preferably 30 mm or less, more preferably 5 to 10 mm.
　また、テープ３上またはその近傍の所定位置に表示される１次元または２次元コード１６の縦幅Ｄは、先行・後行積層フィルム１、１’の送り速度および検出器の精度等に合わせて決定することが好ましい。一方、横幅Ｌ（一方のクワイエットゾーン端から他方のクワイエットゾーン端まで長さ）は、検出器によって少なくとも１つのコード１６を正確に読み取れるようにするため、積層フィルム１、１’のフィルム幅の１／２以下の大きさにすることが好ましい。これによれば、積層フィルム１、１’を連結するテープ３上に確実に１つのコード１６が含まれることになる。
　また、図２に示すように１次元または２次元コード１６をテープ３上に設ける場合の、最大縦幅は、テープ３の縦幅ｄに依存するため、好ましくは３０ｍｍ以下、より好ましくは５～１０ｍｍとする。 Further, the vertical width D of the one-dimensional or two-dimensional code 16 displayed at a predetermined position on or near the tape 3 is adjusted in accordance with the feeding speed of the preceding / following laminated films 1, 1 ′, the accuracy of the detector, and the like. It is preferable to determine. On the other hand, the lateral width L (the length from one quiet zone end to the other quiet zone end) is set to 1 of the film width of the laminated films 1 and 1 ′ so that at least one code 16 can be accurately read by the detector. It is preferable to make it a size of / 2 or less. According to this, one cord 16 is surely included on the tape 3 connecting the laminated films 1 and 1 ′.
Further, as shown in FIG. 2, when the one-dimensional or two-dimensional code 16 is provided on the tape 3, the maximum vertical width depends on the vertical width d of the tape 3, and is preferably 30 mm or less, more preferably 5 to 10 mm.
　１次元コードおよび２次元コード１６としては、一般的に利用されているＪＡＮコードの他、一次元コードとして、ＣＯＤＥ３９、ＩＴＦ、２ｏｆ５、ＮＷ―７、ＣＯＤＥ１２８、ＣＯＯＰ２ｏｆ５、ＣＯＤＥ９３、ＧＳ１　ＤａｔａＢａｒ、ＧＳ１１２８、ＵＰＣ－Ｅ、ＵＰＣＡなど、二次元コードとして、ＱＲ、Ｄａｔａ　Ｍａｔｒｉｘ、ＰＤＦ４１７、ＭｉｃｒｏＰＤＦ４１７、Ｍａｘｉ　Ｃｏｄｅ、ＣＳＩ合成シンボルなど種々のものを使用することができる。 As the one-dimensional code and the two-dimensional code 16, in addition to the commonly used JAN code, the one-dimensional code includes CODE39, ITF, 2of5, NW-7, CODE128, COOP2of5, CODE93, GS1, DataBar, GS1128, UPC -Various codes such as QR, Data Matrix, PDF417, MicroPDF417, Maxi Code, and CSI composite symbols can be used as two-dimensional codes such as E and UPCA.
　なお、テープ３が、紙、布、金属箔またはフィルムを基材とし、一方の面に粘着剤を有する粘着テープ４からなる場合には、基材の一方の面に１次元または２次元コード１６を設ける。該粘着テープ４は、例えば、基材（ＰＥＴ：約３０μｍ）／印刷（コード柄＋遮光性インキ）／粘着剤（アクリル系：約２０μｍ）や、印刷（コード柄）／基材（ＰＥＴ：約３０μｍ）／粘着剤（アクリル系：約２０μｍ）等によって構成する。 When the tape 3 is made of the adhesive tape 4 having paper, cloth, metal foil or film as a base material and having an adhesive on one surface, the one-dimensional or two-dimensional code 16 is provided on one surface of the base material. Is provided. The adhesive tape 4 is, for example, a substrate (PET: about 30 μm) / printing (code pattern + light-shielding ink) / adhesive (acrylic: about 20 μm) or printing (code pattern) / base material (PET: about 30 μm) / adhesive (acrylic: about 20 μm).
　ところで、先行・後行積層フィルム１、１’が、例えば、商品の外装材などに利用される場合には、テープ３として粘着テープ４およびラミネートフィルムからなる帯状フィルム５のいずれも利用することができる。
　一方、先行・後行積層フィルム１、１’が、液状や粉状などの被包装物を充填包装するための包装袋として使用される場合には、積層フィルム１、１’を幅方向で二つ折りにして、それを縦方向および横方向にヒートシールして製袋する。そのため、テープ３として、例えば、先行・後行積層フィルム１、１’と異質の粘着テープを用いてしまうと、シーラント層を十分に加熱溶融させることができず、シール強度が弱くなって液漏れの原因になるおそれがあり、充填包装機を停止させる必要がある。したがって、被包装物を充填包装するための包装袋に利用される先行・後行積層フィルム１、１’の繋ぎ部分に用いられるテープ３としては、ラミネートフィルムからなる帯状フィルムを用いることが好ましい。 By the way, when the leading / following laminated films 1 and 1 ′ are used, for example, as a packaging material for goods, it is possible to use both the adhesive tape 4 and the belt-like film 5 made of a laminate film as the tape 3. it can.
On the other hand, when the leading / following laminated films 1 and 1 ′ are used as packaging bags for filling and packaging an object to be packaged such as liquid or powder, the laminated films 1 and 1 ′ are Fold it up and heat seal it in the vertical and horizontal directions to make a bag. Therefore, if, for example, an adhesive tape that is different from the preceding / following laminated films 1, 1 ′ is used as the tape 3, the sealant layer cannot be sufficiently heated and melted, and the sealing strength is weakened and the liquid leaks. It is necessary to stop the filling and packaging machine. Therefore, it is preferable to use a belt-like film made of a laminate film as the tape 3 used for the connecting portion of the preceding and succeeding laminated films 1 and 1 ′ used in a packaging bag for filling and packaging an article to be packaged.
　以下、帯状フィルム５を用いて先行・後行積層フィルム１、１’を連結した場合の構造を図３の断面図を用いて説明する。
　帯状フィルム５は、延伸または無延伸フィルムからなる中間層５ｂと、その両面に設けたシーラント層５ａ、５ｃとの、両面シール性ラミネートフィルムからなる。一方のシーラント層５ａは、前記したように先行積層フィルム１の尾端部と後行積層フィルム１’の先端部の突き合わせ部である繋ぎ目２の、シーラント層１ｂ、１ｂ’側の面に加熱融着させる。なお、１次元コードまたは２次元コード１６を帯状フィルム５上に設ける場合には、例えば、前記したように帯状フィルム５の中間層５ｂの、シーラント層５ａ側またはシーラント層５ｃ側のいずれか一方の表面に印刷することにより形成できる。
　これによって、帯状フィルム５のシーラント層５ｃと先行・後行積層フィルム１、１’のシーラント層１ｂ、１ｂ’とが、帯状フィルム５の全幅にわたって相互に溶着することになり、繋ぎ目２におけるフィルム繋ぎ部分の連結強度が向上する。この連結方法によれば、多層の厚膜フィルムやアルミニウム箔を積層してなるフィルムなども強固に連結することが可能となり、大容量の大袋やホットパックなどにも適用することができる。 Hereinafter, the structure in the case where the preceding and following laminated films 1 and 1 ′ are connected using the belt-like film 5 will be described with reference to the cross-sectional view of FIG. 3.
The belt-like film 5 is made of a double-sided sealing laminate film comprising an intermediate layer 5b made of a stretched or non-stretched film and sealant layers 5a and 5c provided on both sides thereof. One sealant layer 5a is heated on the surface on the side of the sealant layers 1b and 1b 'of the joint 2 which is a butt portion between the tail end portion of the preceding laminated film 1 and the leading end portion of the following laminated film 1' as described above. Fuse. When the one-dimensional code or the two-dimensional code 16 is provided on the belt-like film 5, for example, as described above, either one of the intermediate layer 5b of the belt-like film 5 on the sealant layer 5a side or the sealant layer 5c side is used. It can be formed by printing on the surface.
As a result, the sealant layer 5c of the belt-like film 5 and the sealant layers 1b, 1b 'of the preceding and following laminated films 1, 1 ′ are welded to each other over the entire width of the belt-like film 5, and the film at the joint 2 The connection strength of the connecting portion is improved. According to this connection method, a multilayer thick film, a film formed by laminating aluminum foil, or the like can be firmly connected, and can be applied to a large-capacity large bag or a hot pack.
　なお、先行積層フィルム１の尾端部と後行積層フィルム１’の先端部との繋ぎ目２位置に、帯状フィルム５を加熱融着する方法としては、たとえば、帯状フィルム５を、先行・後行積層フィルム１、１’の走行方向と直行する方向から、先行・後行積層フィルム１、１’のシーラント層１ｂ、１ｂ’の繋ぎ目２に沿って挿入した後、繋ぎ目２および帯状フィルム５を、押え板とインパルスシーラーとで挟み込み、通電、加熱して帯状フィルム５を融着させる方法がある。このとき、ヒートシール温度は、先行・後行積層フィルム１、１’や帯状フィルム５のフィルム構成によって適宜選択する。 In addition, as a method of heat-sealing the belt-like film 5 at the joint 2 position between the tail end portion of the preceding laminated film 1 and the tip portion of the following laminated film 1 ′, for example, the belt-like film 5 After inserting along the joint 2 of the sealant layers 1b and 1b 'of the preceding and succeeding laminated films 1, 1' from the direction perpendicular to the traveling direction of the row laminated films 1, 1 ', the joint 2 and the strip film There is a method in which the belt-shaped film 5 is fused by sandwiching 5 between a pressing plate and an impulse sealer, energizing and heating. At this time, the heat seal temperature is appropriately selected according to the film configuration of the preceding / following laminated films 1, 1 ′ and the belt-like film 5.
　この帯状フィルム５によれば、例えば、図５に示すような自動充填機においても、先行・後行積層フィルム１、１’の繋ぎ目２位置を正確に検出し、被包装物を充填した後、帯状フィルム５の付いた充填袋のみを不良品として自動で排出させることができる。
　この自動充填機は、原反ロール６から間欠的もしくは連続的に繰り出された積層フィルム１、１’の走行を案内する複数本のガイドロール７と、ガイドロール７を通過した積層フィルム１、１’を、幅方向の中央部で、シーラント層が相互に対向する姿勢に半折りするフィルム折り返し部８と、このフィルム折り返し部８によって折り返された積層フィルム１、１’のそれぞれの遊端部分に、たとえば連続的に縦方向の融着接合部９を形成する縦シール機構１０と、融着接合部９が形成された筒状の積層フィルム１、１’の内側へ、被包装物を間欠的もしくは連続的に充填する充填手段、図では充填ノズル１１と、被包装物を充填された筒状の積層フィルム１、１’に、底部および頂部の横方向融着接合部のための融着接合部１２を形成する横シール機構１３とを具える。 According to this belt-like film 5, for example, even in an automatic filling machine as shown in FIG. 5, after the position of the joint 2 of the preceding and following laminated films 1 and 1 ′ is accurately detected and the packaged material is filled, Only the filled bag with the belt-like film 5 can be automatically discharged as a defective product.
The automatic filling machine includes a plurality of guide rolls 7 for guiding the travel of the laminated films 1 and 1 ′ intermittently or continuously drawn from the raw roll 6, and the laminated films 1 and 1 that have passed through the guide rolls 7. 'At the center of the width direction, the film folded portion 8 half-folded in such a manner that the sealant layers face each other, and the free end portions of the laminated films 1, 1' folded by the film folded portion 8 For example, the object to be packaged is intermittently placed inside the longitudinal sealing mechanism 10 that continuously forms the fusion-bonding portion 9 in the vertical direction and the cylindrical laminated films 1 and 1 ′ on which the fusion-bonding portion 9 is formed. Alternatively, a fusion means for continuously filling, in the drawing, a filling nozzle 11 and a cylindrical laminated film 1, 1 ′ filled with an article to be packaged, are fusion bonded for the bottom and top lateral fusion bonded portions. Horizontal sea forming part 12 It comprises a mechanism 13.
　また、図示の自動充填機では、上述したところに加え、一対の横シールローラからなる横シール機構１３によって形成された融着接合部１２を、再度挟持してその融着接合強度を高めるべく機能する第２の横シール機構１３ａと、間欠的もしくは連続的に製造されて相互に連続する包装体１４を一体ずつ、もしくは所要の複数体ずつに切断分離するカッター手段１５とを具える。 Further, in the illustrated automatic filling machine, in addition to the above, the function of increasing the fusion-bonding strength by sandwiching again the fusion-bonding portion 12 formed by the horizontal-seal mechanism 13 including a pair of horizontal-seal rollers. And a cutter means 15 that cuts and separates the package bodies 14 that are intermittently or continuously manufactured and continuous to each other into one piece or a plurality of required pieces.
　このような自動充填機において、例えば、図５に示すように原反ロール６から積層フィルム１、１’を、ガイドロール７を介して繰り出し走行させる位置に検出器１７を設け、該検出器１７によって帯状フィルム５上またはその近傍の所定位置に表示された１次元または２次元コード１６を検出する。これによれば、積層フィルム１、１’の繋ぎ目２位置が特定されることになり、カッター手段１５の後段位置に設けた選別手段（図示しない）によって正常な包装体１４と、帯状フィルム５の付いた不良品となる包装体１４’とが選別されて、不良品となる包装体１４’のみを自動で排出させることもできる。 In such an automatic filling machine, for example, as shown in FIG. 5, a detector 17 is provided at a position where the laminated film 1, 1 ′ is fed out from the raw roll 6 through the guide roll 7. The one-dimensional or two-dimensional code 16 displayed at a predetermined position on or near the belt-like film 5 is detected. According to this, the joint 2 position of the laminated films 1, 1 ′ is specified, and the normal packaging body 14 and the belt-like film 5 are selected by the sorting means (not shown) provided at the subsequent stage position of the cutter means 15. It is also possible to sort out the packaging body 14 'which becomes a defective product with a mark, and automatically discharge only the packaging body 14' which becomes a defective product.
　なお、帯状フィルム５の中間層５ｂは、延伸または無延伸の、ナイロンフィルム、ポリエチレンテレフタレートフィルムなどの各種プラスチックフィルムや蒸着フィルム、紙、金属箔などからなり、その厚みは、５０μｍ以下であることが好ましく、より好ましくは９～３０μｍ以下とする。これは、中間層５ｂの厚みが薄すぎると連結強度が低くなり、一方、厚すぎると、ストラップフィルム５部分が、製袋時に十分に加熱融着されず、シール強度が弱くなって、充填の際に液漏れしやすくなるからである。 The intermediate layer 5b of the belt-like film 5 is composed of various stretched or unstretched plastic films such as nylon film and polyethylene terephthalate film, vapor-deposited film, paper, metal foil, etc., and the thickness thereof is 50 μm or less. The thickness is preferably 9 to 30 μm or less. This is because if the thickness of the intermediate layer 5b is too thin, the connection strength is low, whereas if it is too thick, the strap film 5 portion is not sufficiently heat-sealed at the time of bag making, and the sealing strength is weakened. This is because liquid leakage easily occurs.
　一方、帯状フィルム５を構成するシーラント層５ａ、５ｃは、熱可塑性を有するポリエチレンやポリプロピレン等の各種プラスチックフィルムからなり、各層５ａ、５ｃの厚みは５０μｍ以下であることが好ましく、より好ましくは５～３０μｍの範囲とする。さらに、帯状フィルム５全体の厚みは、１００μｍ以下であることが好ましく、より好ましくは１９～８５μｍの範囲とする。これは、シーラント層５ａ、５ｃの厚みが薄すぎると、ストラップフィルム５が軟らかくなり過ぎて取り扱いが難しくなり、一方、厚すぎると、ストラップフィルム５部分が、製袋時に十分に加熱融着されず、シール強度が弱くなって、充填の際に液漏れしやすくなるからである。 On the other hand, the sealant layers 5a and 5c constituting the belt-like film 5 are made of various plastic films such as polyethylene and polypropylene having thermoplasticity, and the thickness of each layer 5a and 5c is preferably 50 μm or less, more preferably 5 to The range is 30 μm. Furthermore, the thickness of the entire belt-like film 5 is preferably 100 μm or less, and more preferably in the range of 19 to 85 μm. This is because if the thickness of the sealant layers 5a and 5c is too thin, the strap film 5 becomes too soft and difficult to handle. On the other hand, if it is too thick, the strap film 5 portion is not sufficiently heat-sealed during bag making. This is because the sealing strength is weakened and the liquid is liable to leak during filling.
　なお、検出器１７としては、上記１次元または２次元コード１６を、離れた位置からも検出できるもの（離し読み式）であることが好ましく、例えば、レーザやＬＥＤ光源等を利用したコードリーダや画像検出・処理器が好適に用いられる。
　また、検出器１７が、検出対象の複数のコード規格またはコード番号を設定することのできる機能を有する場合には、テープ３上またはその近傍の所定位置に表示されたコード１６のコード規格あるいはコード番号毎に制御を行うことが可能となる。この検出器１７によれば、例えば、図５の自動充填機により充填包装する際に、不良品として選別された包装体１４’の排出先をコード１６の種類毎に変えることや、テープ３が粘着テープ４の場合と帯状フィルム５の場合で、コード１６を異ならせ、テープ３の種類毎に自動充填機の動作を変更させること（粘着テープの場合：充填機を停止させる、帯状フィルムの場合：自動排出させる等）等、様々な制御を行うことができる。 The detector 17 is preferably one that can detect the one-dimensional or two-dimensional code 16 from a distant position (separate reading type). For example, a code reader using a laser, an LED light source, or the like An image detector / processor is preferably used.
When the detector 17 has a function capable of setting a plurality of code standards or code numbers to be detected, the code standard or code of the code 16 displayed on the tape 3 or at a predetermined position in the vicinity thereof. Control can be performed for each number. According to this detector 17, for example, when filling and packaging with the automatic filling machine of FIG. 5, the discharge destination of the package 14 ′ selected as a defective product can be changed for each type of the code 16, or the tape 3 In the case of the pressure-sensitive adhesive tape 4 and the case of the belt-like film 5, the cord 16 is changed, and the operation of the automatic filling machine is changed for each type of tape 3 (in the case of the pressure-sensitive tape: the case of the belt-like film that stops the filling machine) : Various kinds of control such as automatic discharge).
