Description

本発明は、複数の包装用のフィルム同士を連結するフィルム繋ぎ装置に関し、例えば、粘着テープやその他の連結用資材を使用することなく、連結するためのフィルム繋ぎ装置に適用できる。   The present invention relates to a film connecting device that connects a plurality of packaging films, and can be applied to, for example, a film connecting device for connecting without using an adhesive tape or other connecting materials.

従来、送りローラ等のフィルム送出手段によってフィルム原反から連続移送される長尺状のフィルム一枚を二つ折りにして重ね合せるか、または二枚を重ね合せ、その重なり合った縁部を縦シールして縦シール部を形成するとともに、重ね合せたフィルムを横シールして底部となる横シール部を形成し、前記フィルムの移送方向に対して前記横シール部から後方となる開放筒上部に内容物を所定量充填した後、一定間隔にて再び横シールして横シール部を形成することにより、連続的な密閉包装袋（連続包装袋）を形成し、刃体を有する切断手段によってフィルムに形成された横シール部の略中央箇所を切断することによって包装袋を製造する包装装置がある（例えば、特許文献１参照）。   Conventionally, a long film continuously transported from the original film by a film feeding means such as a feed roller is folded in two or overlapped, or two sheets are overlapped, and the overlapping edges are vertically sealed. In addition to forming a vertical seal portion, the stacked films are laterally sealed to form a bottom seal portion, and the contents are placed at the top of the open cylinder that is rearward from the horizontal seal portion with respect to the film transfer direction. After a predetermined amount is filled, it is horizontally sealed again at regular intervals to form a laterally sealed portion, thereby forming a continuous hermetic packaging bag (continuous packaging bag), which is formed into a film by a cutting means having a blade body There is a packaging device that manufactures a packaging bag by cutting a substantially central portion of a horizontal seal portion (see, for example, Patent Document 1).

ところで、前記包装装置の包装材として用いられるフィルムは、交換する手間を省いて包装作業を効率よく行なえるように一般に長さの長いものが用いられる。この長いフィルムを得るための製造上、所定長さを有する複数のフィルムの端部同士を互いに繋ぎ合わせるものを使用する場合がある。したがって、フィルム同士を繋ぎ合わせるフィルム繋ぎ装置が求められており種種に提案されていた（例えば、特許文献２参照）。   By the way, as the film used as the packaging material of the packaging apparatus, a film having a long length is generally used so that the packaging work can be efficiently performed without the trouble of replacement. In order to obtain this long film, there is a case in which a plurality of films having a predetermined length are joined to each other. Therefore, there has been a demand for a film joining device that joins films together, and has been proposed for various types (for example, see Patent Document 2).

上述のような包装装置に適用されるフィルムは、ベースフィルム層と熱溶融樹脂層（融着層）とが積層されてなるフィルムが一般的である。これを利用して、２つのフィルムの熱溶融樹脂層同士を合掌状に対向させた後、融着によって接し合わせるフィルム繋ぎ装置が提案されている（例えば、特許文献２参照）。この場合、粘着用テープやその他の連結用資材を使用することが必要ないだけでなく、気密性に優れたフィルムの繋ぎ合わせを行うことができる。   The film applied to the packaging apparatus as described above is generally a film in which a base film layer and a hot-melt resin layer (fusion layer) are laminated. Utilizing this, a film joining apparatus has been proposed in which hot-melt resin layers of two films are opposed to each other in the form of a palm and then brought into contact by fusion (for example, see Patent Document 2). In this case, it is not necessary to use an adhesive tape or other connecting materials, and it is possible to join films having excellent airtightness.

特開平８−４８３０１号公報JP-A-8-48301 特開昭６１−７２５２４号公報JP-A-61-72524

前述したフィルム繋ぎ装置は、対向するシーラ（溶融部材）間に２つのフィルムをフィルム面に対して直交する方向から差し込む平坦面形状の挿入板（インサート部材）を設けて、フィルムを合掌状に対向させるようにしている。しかしながら、前記平坦面形状の挿入板によってフィルムの側部を押し出してフィルム同士を対向させる際に、前記挿入板に対して各フィルムが幅方向に滑るなどして、フィルム同士が多少ずれた位置にて対向して配設されてしまう虞があった。この状態にて融着して繋ぎ合わされたフィルムを用いて前記包装装置によって前記内容物を包装した場合、繋ぎ目以降のフィルムの折り返し端部に位置ずれが生じたままで適正に重なり合わなかったり、この位置ずれを起因にしてシール不良が発生してしまうという可能性があり問題となっていた。   The above-described film joining device is provided with a flat surface-shaped insertion plate (insert member) that inserts two films from opposite directions to the film surface between opposing sealers (melting members), so that the films face each other in the shape of a palm. I try to let them. However, when the side portions of the film are pushed out by the flat plate-shaped insertion plate and the films are opposed to each other, each film slides in the width direction with respect to the insertion plate, so that the films are slightly shifted from each other. There is a risk that they will be arranged facing each other. When the contents are packaged by the packaging device using the film fused and joined in this state, the folded end of the film after the joint has not been properly overlapped, There is a possibility that a seal failure may occur due to this positional deviation, which has been a problem.

そこで、本発明は上述した問題について着目してなされたものであって、フィルム繋ぎ箇所によるフィルム同士の位置ずれを防止して、適正なフィルム繋ぎを行うことが可能なフィルム繋ぎ装置を提供することを目的とするものである。   Then, this invention is made paying attention to the problem mentioned above, Comprising: The film joining apparatus which prevents the position shift of the films by a film joining location, and can perform an appropriate film joining is provided. It is intended.

上述した課題を解決するために、本発明のフィルム繋ぎ装置は、請求項１に記載したように、片面に融着層を有するフィルム同士を連結するフィルム繋ぎ装置であって、所定間隔おいて対向して配設され互いが開閉移動可能な一対のシーラと、前記フィルムとの当接箇所が凹形状もしくは凸形状にて形成され前記フィルムを前記シーラ間の所定位置に差し込む挿入板と、を備えてなることを特徴とするものである。   In order to solve the above-described problems, a film joining apparatus according to the present invention is a film joining apparatus for connecting films having a fusion layer on one side, as described in claim 1, and facing each other at a predetermined interval. And a pair of sealers that can be opened and closed with each other, and an insertion plate in which a contact portion with the film is formed in a concave shape or a convex shape, and the film is inserted into a predetermined position between the sealers. It is characterized by.

また、本発明のフィルム繋ぎ装置は、請求項２に記載したように、片面に融着層を有するフィルム同士を連結するフィルム繋ぎ装置であって、所定間隔おいて対向して配設され互いが開閉移動可能な一対のシーラと、前記フィルムに対して位置ずれを防止する滑り止め部材を前記フィルムとの当接箇所もしくは前記当接箇所の一部に設け前記フィルムを前記シーラ間の所定位置に差し込む挿入板と、を備えてなることを特徴とするものである。   Moreover, the film joining device of the present invention is a film joining device for connecting films having a fusion layer on one side, as described in claim 2, and is arranged facing each other at a predetermined interval. A pair of sealers that can be opened and closed, and a non-slip member that prevents displacement with respect to the film are provided at a contact position with the film or a part of the contact position, and the film is placed at a predetermined position between the sealers. And an insertion plate to be inserted.

本発明は、片面に融着層を有するフィルム同士を連結するフィルム繋ぎ装置に関し、フィルム同士の位置ずれを防止して、適正なフィルム繋ぎを行うことが可能なフィルム繋ぎ装置を提供できる。   The present invention relates to a film joining device for joining films having a fusion layer on one side, and can provide a film joining device capable of preventing misalignment between films and performing appropriate film joining.

以下、添付図面に基づいて本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１から図４において、供給状態にあるフィルムＦ１と待機状態にあるフィルムＦ２を繋ぎ合わせて切り換えるフィルム切り換え装置Ａに適用したものについて例に挙げて説明する。フィルム切り換え装置Ａは、それぞれが図示しない機台に支持されるフィルム供給機構１と、フィルム移送機構２と、フィルム繋ぎ機構（フィルム繋ぎ装置）３と、挿入機構４と、から主に構成される。   In FIG. 1 to FIG. 4, an example applied to the film switching device A that switches the film F1 in the supply state and the film F2 in the standby state by connecting them will be described. The film switching device A is mainly composed of a film supply mechanism 1, a film transfer mechanism 2, a film connection mechanism (film connection device) 3, and an insertion mechanism 4 each supported by a machine base (not shown). .

フィルム供給機構１は、軸部１１，１２のそれぞれに着脱交換可能に回転軸支されているフィルム原反Ｒ１，Ｒ２からフィルムＦ１，Ｆ２を供給するものである。フィルムＦ１およびフィルムＦ２は、アルミまたはナイロン等のからなるベースフィルムＦ１１，Ｆ２１と、低密度ポリエチレンからなる延伸可能な熱溶融樹脂層（融着層）Ｆ１２，Ｆ２２との積層体を適用でき、長尺形状のものがロール状に巻回されたフィルム原反Ｒ１，Ｒ２から引き出されて供給される。なお、フィルムＦ１とフィルムＦ２とは、同じ厚みおよび幅寸法のものが用いられる。また、待機状態であるフィルムＦ２は、その端縁部がクリップ等からなる係止部材１３によって所定位置に係止される。   The film supply mechanism 1 supplies films F1 and F2 from film originals R1 and R2 that are rotatably supported by shafts 11 and 12 so as to be detachable and replaceable. As the films F1 and F2, a laminate of base films F11 and F21 made of aluminum or nylon and stretchable heat-melting resin layers (fused layers) F12 and F22 made of low-density polyethylene can be applied. A scale-shaped one is drawn out and supplied from the original film R1, R2 wound in a roll. In addition, the thing with the same thickness and width dimension is used for the film F1 and the film F2. Further, the film F2 in the standby state is locked at a predetermined position by the locking member 13 whose edge is made of a clip or the like.

フィルム移送機構２は、サーボモータからなる駆動手段を駆動源として回転可能に設けられフィルムＦ１を挟んで対向する一対のロール２１によって、フィルムＦ１を所定速度にて繰り出すものである。   The film transfer mechanism 2 is rotatably provided with a drive unit including a servo motor as a drive source, and feeds the film F1 at a predetermined speed by a pair of rolls 21 facing each other with the film F1 interposed therebetween.

フィルム繋ぎ機構３は、ベース部３１，３２と、挿入板３３と、シール部（シーラ）３４と、切断部３５とから構成され、フィルムＦ１とフィルムＦ２とを繋ぎ合わせて連結状態にするものである。   The film connecting mechanism 3 is composed of base parts 31, 32, an insertion plate 33, a seal part (sealer) 34, and a cutting part 35, and connects the film F1 and the film F2 into a connected state. is there.

ベース部３１，３２は、フィルム供給機構１からフィルム移送手段２までのフィルム移送経路の近傍箇所に設けられる一対の部材である。また、ベース部材３１，３２は、互いに隙間を有して配設されるとともに、少なくとも片方のベース部３１には、シリンダ等の図示しない駆動手段が設けられ、他方のベース部３２に対して近接または遠隔方向に開閉動作（対向移動）可能に設けられている。   The base portions 31 and 32 are a pair of members provided in the vicinity of the film transfer path from the film supply mechanism 1 to the film transfer means 2. The base members 31 and 32 are arranged with a gap therebetween, and at least one base portion 31 is provided with a driving means (not shown) such as a cylinder, and is close to the other base portion 32. Alternatively, it can be opened and closed (opposite movement) in the remote direction.

挿入板３３は、フィルムＦ１の側部およびフィルムＦ２の端縁部近傍をベース部３１，３２間の隙間に差し込むようにして挿入するものである。この場合、挿入板３３は、図示しないシリンダ等の駆動手段によって、フィルムＦ１の移送方向に対して略垂直に往復移動されて、挿入板３３の先端部３３ＡによってフィルムＦ１，Ｆ２を差し込まれるように構成される。先端部３３Ａは、図３に示すように、その中央部箇所が湾曲した凸形状に形成されている。   The insertion plate 33 is inserted so that the side of the film F1 and the vicinity of the edge of the film F2 are inserted into the gap between the base portions 31 and 32. In this case, the insertion plate 33 is reciprocated substantially perpendicularly to the transfer direction of the film F1 by driving means such as a cylinder (not shown) so that the films F1 and F2 are inserted by the distal end portion 33A of the insertion plate 33. Composed. As shown in FIG. 3, the tip portion 33A is formed in a convex shape with a curved central portion.

なお、挿入板３３がフィルムＦ１，Ｆ２を押し出す際には、まず、前記凸形状の凸部分がフィルムＦ１，Ｆ２の中央部に接触し、この接触箇所を基点として、フィルムＦ１，Ｆ２の弛みや皺などをフィルムＦ１，Ｆ２の縁方向（外側）へ受け流すことができる。また、挿入板３３は、従来構造の平坦状からなる先端部がフィルムと一度に接触してしまうものに比べて、局部的な力をフィルムＦ１，Ｆ２に加えつつ徐々にフィルムＦ１，Ｆ２と接触することができるため、フィルムＦ１，Ｆ２と挿入板３３とがずれにくい構造となる。したがって、フィルムＦ１とフィルムＦ２とが幅方向にずれないように対向して重なり合った状態を容易に維持することが可能となる。また、挿入板３３は、前記駆動手段によって、ベース部３１の閉動作するまでのタイミングにて、ベース部３１，３２間から引き出される。   When the insertion plate 33 pushes out the films F1 and F2, first, the convex portion of the convex shape comes into contact with the central portion of the films F1 and F2, and the looseness of the films F1 and F2 is determined based on the contact point. A wrinkle etc. can be poured in the edge direction (outside) of film F1, F2. In addition, the insertion plate 33 gradually contacts the films F1 and F2 while applying a local force to the films F1 and F2 as compared with the case where the flat end portion of the conventional structure contacts the film at a time. Therefore, the films F1 and F2 and the insertion plate 33 are not easily displaced. Therefore, it is possible to easily maintain a state in which the film F1 and the film F2 face each other so as not to shift in the width direction and overlap each other. Further, the insertion plate 33 is pulled out from between the base portions 31 and 32 at a timing until the base portion 31 is closed by the driving means.

シール部３４は、ベース部３１，３２の対向箇所に設けられるインパルスシーラが適用でき、フィルムＦ１，Ｆ２に接触することによって、その接触箇所近傍の熱溶融樹脂層Ｆ１２，Ｆ２２を溶融するものである。なお、シール部３４は、フィルムＦ１，Ｆ２に対して幅方向の全幅に渡って接触するように設けられる。また、シール部３４は、図４に示すように、ベース部３１，３２間に差し込まれたフィルムＦ１，Ｆ２を、ベース部３１の閉動作によって、対向するベース部３２とシール部３４との間に挟み込んで押圧することができる。この状態において、シール部３４は、フィルムＦ１，Ｆ２に対して接触しつつ発熱することによって熱溶融樹脂層Ｆ１２，Ｆ２２を溶融する。また、前記溶融状態となった後、ベース部３１の開動作によってフィルムＦ１，Ｆ２とシール部３４とが離間し、前記溶融部分が冷却硬化されて熱溶融樹脂層Ｆ１２，Ｆ２２同士が融着されてフィルムＦ１，Ｆ２を繋ぎ合わせることができる。また、前記溶融部分は、連結状態のフィルムＦ１，Ｆ２の繋ぎ目となる。   The seal portion 34 can be applied with an impulse sealer provided at a location facing the base portions 31 and 32, and melts the hot-melt resin layers F12 and F22 in the vicinity of the contact location by contacting the films F1 and F2. . The seal portion 34 is provided so as to contact the films F1 and F2 over the entire width in the width direction. Further, as shown in FIG. 4, the seal portion 34 is formed between the opposing base portion 32 and the seal portion 34 by closing the base portion 31 with the films F <b> 1 and F <b> 2 inserted between the base portions 31 and 32. And can be pressed. In this state, the seal portion 34 melts the hot-melt resin layers F12 and F22 by generating heat while being in contact with the films F1 and F2. Further, after the molten state is reached, the films F1 and F2 and the seal portion 34 are separated by the opening operation of the base portion 31, the melted portion is cooled and cured, and the hot-melt resin layers F12 and F22 are fused. Thus, the films F1 and F2 can be joined together. Moreover, the said melt | fusion part becomes a joint of film F1, F2 of a connection state.

切断刃３５は、ベース部３１，３２の対向箇所において、シール部３４の近傍でフィルムＦ１の移送経路側と逆側（挿入状態における挿入板３３の先端部３３Ａ側）に配設される。切断刃３５は、対向するベース部３２に対して進退可能に設けられ、フィルムＦ１，Ｆ２を切断することができる。この切断刃３５により、シール部３４によって形成された繋ぎ目付近におけるフィルムＦ１，Ｆ２の余剰部分を取り除くことができる。   The cutting blade 35 is disposed near the seal portion 34 on the opposite side of the base portions 31 and 32 on the side opposite to the transfer path side of the film F1 (on the distal end portion 33A side of the insertion plate 33 in the inserted state). The cutting blade 35 is provided so as to be able to advance and retreat with respect to the opposing base portion 32, and can cut the films F1 and F2. The cutting blade 35 can remove excess portions of the films F1 and F2 in the vicinity of the joint formed by the seal portion 34.

なお、シール機構３の開閉動作は、フィルム移送機構２または、別体に設けられるピンチローラ等からなるフィルム停止機構によって、供給状態にあるフィルムＦ１の移送を停止した状態にてなされる。また、上述したシール機構３の動作によって繋ぎ目が形成された後、フィルム移送機構２によって、再びフィルムＦ１および繋ぎ目を介してフィルムＦ２をベース部３１，３２間から引き出すようにして移送することで、供給状態にあるフィルムＦ１からフィルムＦ２へ切り換えることができる。   The opening / closing operation of the seal mechanism 3 is performed in a state where the transfer of the film F1 in the supply state is stopped by the film transfer mechanism 2 or a film stop mechanism including a pinch roller or the like provided separately. Further, after the joint is formed by the operation of the sealing mechanism 3 described above, the film transport mechanism 2 transports the film F2 again through the base portions 31 and 32 through the film F1 and the joint. Thus, the film F1 in the supply state can be switched to the film F2.

また、上述した各機構の各種駆動手段は、マイクロコンピュータからなる制御手段（図示しない）と電気的に接続されるとともに、前記制御手段からの制御信号によって動作が制御されるように構成されている。前記制御手段は、予め格納されたプログラムに基づいて、上述のフィルムＦ１，Ｆ２の繋ぎ合わせ等の処理を促す制御信号を、前記各駆動手段に出力するものである。   The various drive means of each mechanism described above are electrically connected to a control means (not shown) formed of a microcomputer, and are configured to be controlled by a control signal from the control means. . The control means outputs a control signal for prompting processing such as joining of the films F1 and F2 to the driving means based on a program stored in advance.

かかる構成により、本発明は、片面に融着層を有するフィルムＦ１，Ｆ２の端部もしくは側部を連結するフィルム繋ぎ機構３であって、所定間隔おいて対向して配設され互いが開閉移動可能な一対のシール部３４と、フィルムＦ１，Ｆ２との当接箇所が凹形状もしくは凸形状にて形成され、フィルムＦ１，Ｆ２をシール部３４間の所定位置に差し込む挿入板３３と、を備えてなることによって、フィルムＦ１とフィルムＦ２とが幅方向に位置ずれすることを防止できるため、フィルムＦ１，Ｆ２同士がきちんと重なり合った適正状態にてフィルム繋ぎを行うことが可能なフィルム切り換え装置となる。したがって、品質的に良好な包装用のフィルム（包装材）を形成することができる。   With this configuration, the present invention is a film connecting mechanism 3 that connects the ends or sides of the films F1 and F2 each having a fusion layer on one side, which are arranged to face each other at a predetermined interval and open and close each other. A pair of possible seal portions 34 and an insertion plate 33 in which the contact portions with the films F1 and F2 are formed in a concave shape or a convex shape, and the films F1 and F2 are inserted into a predetermined position between the seal portions 34 are provided. Therefore, since the film F1 and the film F2 can be prevented from being displaced in the width direction, the film switching device can perform the film connection in an appropriate state in which the films F1 and F2 are properly overlapped with each other. . Therefore, it is possible to form a packaging film (packaging material) with good quality.

なお、本発明は上述した実施の形態に限定されるものではなく、本発明の効果を得るものであれば、種種の変形が可能である。例えば、シール部３４としてインパルス方式を用いたものを示したが、高周波ウエルダシール方式、超音波シール方式またはレーザ方式等を用いて繋ぎ目を形成してフィルムを連結するものであってもよい。また、フィルムを連結する方法として、接着テープや接着剤を用いて自動的に連結する方法も考えられる。   The present invention is not limited to the above-described embodiment, and various modifications can be made as long as the effects of the present invention are obtained. For example, although the impulse system is used as the seal portion 34, a film may be connected by forming a joint using a high-frequency welder seal system, an ultrasonic seal system, a laser system, or the like. Further, as a method of connecting the films, a method of automatically connecting using an adhesive tape or an adhesive is also conceivable.

また、上述した実施の形態の別例として、図５（ａ）で示すように、挿入板４の先端部４Ａの形状を凹形状としてもよいし、図５（ｂ）で示すように、挿入板５の先端部５Ａの形状を凹凸が連続する波状に形成するものであってもよい。また、図５（ｃ）で示すように、挿入板６の先端部６Ａの形状としてフィルム幅に合わせた凸部６Ｂを設けてなるものであってもよい。   Further, as another example of the above-described embodiment, as shown in FIG. 5A, the shape of the distal end portion 4A of the insertion plate 4 may be a concave shape, or as shown in FIG. The shape of the front end portion 5A of the plate 5 may be formed in a wave shape with continuous irregularities. Moreover, as shown in FIG.5 (c), you may provide the convex part 6B according to the film width as a shape of the front-end | tip part 6A of the insertion board 6.

また、図５（ｄ）で示すように、挿入板７の先端部７Ａにおいて、前記フィルムをシーラ間に差し込む際に、前記フィルムと接触する一部分に合成ゴム等からなるフィルムに対して摩擦係数が高い滑り止め部材７Ｂを貼り付けておくことによって、フィルムと挿入板７との間に発生する位置ずれを防止した構造とすることができる。
Further, as shown in FIG. 5 (d), when the film is inserted between the sealers at the distal end portion 7A of the insertion plate 7, the friction coefficient with respect to the film made of synthetic rubber or the like is partially in contact with the film. By sticking the high anti-slip member 7 </ b> B, it is possible to obtain a structure that prevents the positional deviation generated between the film and the insertion plate 7.
