Description

本発明は、例えば果物や野菜等を収容させた合成樹脂製の上面開放容器その他の被包装物に帯状フィルムを巻き掛けて包装するフィルム包装装置に関する。   The present invention relates to a film wrapping apparatus that wraps and wraps a belt-shaped film around an open top container made of a synthetic resin or the like to contain fruits, vegetables, and the like.

果物や野菜等を収容させた透明な合成樹脂製の上面開放容器内にいちご、プルーン、茸類、カットされた果物その他の果物、野菜等を収納し、その上から帯状フィルムを巻き掛けて包装された商品が日常的に小売り流通されている。帯状フィルムの巻き掛け包装を自動的に行わせる装置として、例えば特開２００２−２０００６号の装置が提案されている。この装置は、両縁部を糊付けされて包装位置Ｐに搬送された短冊フィルムＦを，左右一対の上下ローラ６２，６３に挟持させ、この状態で、短冊フィルムＦの下方で待機するトレイＴの下方から複数の突き上げピン７１が上昇すると、短冊フィルムＦは両縁部を中央側に引っ張られながらトレイＴとともに上昇する。この状態でフィルム端搬送部７５がトレイＴの下面側に挿入されることにより、短冊フィルムの一方の縁部がローラ６２，６３の拘束から離脱してトレイＴの下面に粘着する。その後、トレイ搬送部９０の弾性ベルトがトレイＴの上面を押さえながらトレイＴを移動させると、他方の縁部を他の一対の上下ローラから離脱させてトレイＴの下面に貼着させるものであり、これによって、被包装物に対する帯び掛け作業の自動化を実現しようとしている。   Strawberries, prunes, potatoes, cut fruits and other fruits and vegetables are stored in a transparent synthetic resin top open container containing fruits and vegetables, and a belt-like film is wrapped around them The goods sold are distributed daily. For example, an apparatus disclosed in Japanese Patent Application Laid-Open No. 2002-20006 has been proposed as an apparatus for automatically winding and wrapping a belt-shaped film. In this apparatus, the strip film F glued on both edges and conveyed to the packaging position P is sandwiched between a pair of left and right upper and lower rollers 62 and 63, and in this state, the tray T waiting under the strip film F When the plurality of push-up pins 71 rise from below, the strip film F rises together with the tray T while pulling both edges toward the center. In this state, when the film end conveying portion 75 is inserted into the lower surface side of the tray T, one edge portion of the strip film is released from the restraint of the rollers 62 and 63 and adheres to the lower surface of the tray T. After that, when the tray T is moved while the elastic belt of the tray transport unit 90 presses the upper surface of the tray T, the other edge is separated from the other pair of upper and lower rollers and is attached to the lower surface of the tray T. In this way, it is trying to realize the automation of the tying operation for the packaged object.

しかしながら、上記従来の文献１の装置は、フィルムロールから繰り出して搬送するラインに対してカット後の短冊フィルムを直交方向に持ち上げるように移動させ、持ち上げ上昇端位置でこれを横移動させることにより短冊フィルムを被包装物に糊付けするから、少なくとも被包装物の搬送用ラインが２系統ライン必要となる上に、同文献図２のように複数の突き上げピン７１を含むトレイ押し上げ機構が必要である。また、片側に糊付け後、他端側を被包装物に糊付けするための弾性ベルト９１を含む横搬送機構がさらに必要となるなど、機構が複雑で種々の機能を行う別駆動軸の機構が多く必要になって製造コストを高くし、また、処理工程を多くして全体の時間が長く、作業効率の向上を阻害していた。特に、この文献の装置では、フィルムロールから繰り出し搬送させる際に、上下のフリーベルト１３と駆動ベルト１２との間に挟みこんだ状態でフィルム搬送を行うようにしているので薄くて可撓、柔軟なフィルムの両端の糊部がこれらのベルトに貼りついてしまい、少しの平行度の狂いによってもベルトに巻き込み、全体がまくれあがる等の問題を多発させるものであり、現実には実用化が困難であった。一方、フィルムの両端縁側の非接着面を挟んで搬送すれば少しでも横ずれすると片側が外れ、糊面より内側を挟んで搬送すると両端側だれたり、跳ね上がる問題が生じ包装位置Ｐまで円滑に搬送すること自体が困難であるという課題があった。さらには、繰り出し搬送部と本搬送部とを異なるベルト駆動機構から構成し、さらに搬送側と軸方向を異ならせた上下ローラ６２，６３によりトレイＴの押し上げ時の押さえローラとするなどの駆動機構が必要でそれらの制御も複雑とならざるを得ないという課題があった。（なお、以上は、文献における部材番号とする。）
特開２００２−２０００６号（明細書の特許請求の範囲、段落番号００２５、同００３０、図１、図２、図４、図１０） However, the apparatus of the above-mentioned conventional literature 1 moves the strip film after cutting so as to be lifted in the orthogonal direction with respect to the line fed out from the film roll and transports it, and horizontally moves it at the lifted end position. Since the film is glued to the package, at least two lines for conveying the package are required, and a tray push-up mechanism including a plurality of push-up pins 71 is required as shown in FIG. In addition, there are many mechanisms for separate drive shafts that have various mechanisms and have a complicated mechanism, such as the need for a lateral transport mechanism including an elastic belt 91 for pasting one side and pasting the other end to the package. This necessitates an increase in manufacturing cost and increases the number of processing steps, resulting in a longer overall time, which hinders improvement in work efficiency. In particular, in the apparatus of this document, when the film is fed out from the film roll, the film is conveyed while being sandwiched between the upper and lower free belts 13 and the drive belt 12, so that it is thin, flexible and flexible. The glue on both ends of such a film sticks to these belts, and even a little misalignment causes the belt to get caught in the belt and the whole to turn up. there were. On the other hand, if the film is transported across the non-adhesive surfaces on both ends of the film, one side will come off if it is slightly displaced, and if it is transported on the inside from the glue surface, there will be problems of slipping or jumping up on both ends, and the film will be smoothly transported to the packaging position P There was a problem that it was difficult in itself. Further, the feeding conveyance unit and the main conveyance unit are configured by different belt driving mechanisms, and further, a driving mechanism such as a pressing roller when the tray T is pushed up by the upper and lower rollers 62 and 63 different in the axial direction from the conveyance side. There was a problem that it was necessary and the control of them had to be complicated. (The above is the member number in the literature.)

本発明のフィルム包装装置は、フィルムロールから繰り出されるフィルムを挟持搬送する搬送部と、搬送部から送られてきたフィルムを所定幅長さに切断する切断部と、切断された帯フィルムの両端側を把持した状態で被包装物に被せ動作させる被せ動作部と、被せ動作部の被せ動作位置を含む供給ラインに被包装物を供給する被包装物供給部と、を備え、フィルムの両端側を点当たり状に押圧、解放自在に把持しつつ搬送部と協働してフィルムを被せ動作部側に搬送補助する第１点当たり把持手段を含む構成であるから、第１点当たり把持手段を介して搬送するフィルムの両側を点当たり状に把持して搬送補助できるので、フィルムの両端を確実に把持し、かつ把持した状態からこれを解除する際に点当たり状態から簡単に離脱でき、しかも、両端側の糊付け部をまともに押さえても点当たり保持により確実に離脱させることができ、フィルムの両端側の押さえの機構が搬送部とともに単なる上下動の機構のみで構成でき、構造が簡単で製造コストも低廉に維持しうる。また、フィルム両端側の糊付け部への付着を回避するための特殊な構成を考慮する必要がなく、装置製作上の自由度を大幅に向上させ得る。   The film packaging apparatus of the present invention includes a transport unit that sandwiches and transports a film fed from a film roll, a cutting unit that cuts the film sent from the transport unit into a predetermined width, and both ends of the cut strip film A covering operation part that covers the object to be packaged in a state where the object is gripped, and a packaged object supply part that supplies the object to be packaged to a supply line including a covering operation position of the covering operation part. Since it is configured to include a first-point-holding means that covers the film in cooperation with the transport unit and assists the transport toward the operation unit side while pressing and releasing freely in a spot-point form, Since both sides of the film to be transported can be gripped in a spot-pointed manner, the film can be securely gripped at both ends, and easily removed from the spotted state when releasing the gripped state. Even if the glued parts on both ends are pressed firmly, they can be reliably removed by holding the points, and the pressing mechanism on both ends of the film can be configured with only a vertical movement mechanism together with the transport part, and the structure is simple. Manufacturing costs can also be kept low. In addition, it is not necessary to consider a special configuration for avoiding adhesion to the gluing portions on both ends of the film, and the degree of freedom in manufacturing the device can be greatly improved.

また、被せ動作部は、帯フィルムの両端側を点当たり状に押圧、解放自在に把持する第２点当たり把持手段を含む構成であるから、帯フィルムの両端側のみを把持した状態の場合にも、基本的には第１点当たり把持手段と同様に、フィルムの両端を確実に把持し、かつ把持した状態からこれを解除する際に点当たり状態から簡単に離脱でき、しかも、両端側の糊付け部をまともに押さえても点当たり保持により確実に離脱させることができ、上下動の機構のみで構成でき、また、構造が簡単で製造コストも低廉に維持しうる。   In addition, since the covering operation part includes a second point hitting means that presses both ends of the band film in a spot-like manner and holds them freely, in the state where only the both ends of the band film are held Basically, like the gripping means for the first point, both ends of the film can be securely gripped, and can be easily removed from the spotted state when releasing from the gripped state, Even if the gluing part is pressed down properly, it can be surely released by holding at the point, and it can be constituted by only a vertical movement mechanism, and the structure is simple and the manufacturing cost can be kept low.

また、第１点当たり把持手段は、搬送されるフィルムの両端側において直列状に配置させそれぞれが自由転動自在に設けた複数の球体と、該複数の球体の頂点を含む面に搬送されるフィルムの両端側を位置させてその上面から押さえ、退避自在に設けられた押さえフレームと、を含む構成であるから、直列状に配置させた複数の球体とその上面からの押さえフレームのみの構成で、製造容易な低コストの点当たり把持構成を実現できる。   Further, the gripping means for the first point is transported to a surface including a plurality of spheres arranged in series on both end sides of the film to be transported, each provided so as to freely roll and a vertex including the vertices of the plurality of spheres. Since both ends of the film are positioned and pressed from the upper surface, and the holding frame is provided so as to be retractable, the configuration includes only a plurality of spheres arranged in series and a pressing frame from the upper surface. Therefore, it is possible to realize a low-cost spot-holding configuration that is easy to manufacture.

第２点当たり把持手段は、帯フィルムの両端側において直列状に配置保持させそれぞれが自由転動自在に設けた複数の球体と、該複数の球体の頂点を含む面に帯フィルムの両端側を位置させてその上面から押さえ、退避自在に設けられた第２押さえフレームと、を含む構成であるから、直列状に配置させた複数の球体と押さえフレームのみの構成で、製造容易な低コストの点当たり把持構成を実現できる。また、搬送部や第１点当たり把持手段とともに、たとえばすべてエアシリンダ等による直線動作駆動手段のみでよく、構成の簡易性とともに、その制御駆動系統もすべて電磁弁等による制御構成でよく、機構の簡易化に資する。   The gripping means for hitting the second point includes a plurality of spheres arranged and held in series on both end sides of the band film, each provided so as to be freely rollable, and both end sides of the band film on surfaces including the vertices of the plurality of spheres. And a second presser frame that is provided so as to be positioned and pressed from the upper surface so as to be retractable. Thus, the configuration includes only a plurality of spheres and presser frames arranged in series, and can be manufactured at low cost. A spot-holding configuration can be realized. Further, together with the conveyance unit and the gripping means for the first point, for example, it is only necessary to use only a linear motion drive means such as an air cylinder. Contributes to simplification.

また、被せ動作部は、被包装物供給部の供給ライン上に設定された被せ動作位置を有し、
被せ動作部は、帯フィルムの両端側を把持した状態で下方へ移動させることにより被包装物への帯フィルムの被せ動作を行い、その際、帯フィルムの両端側を対向内側方向に押さえて糊付け部を被包装物の側面側に密着させる幅方向移動機構を有する構成であるから、直線的な下降動作に付随した形態で被包装物の側面側へ確実に接着させることができる。 In addition, the covering operation part has a covering operation position set on the supply line of the package supply part,
The covering operation part moves the band film onto the package by moving it downward while holding both ends of the band film. At that time, the both ends of the band film are pressed in the opposite inner direction and glued. Since it is the structure which has the width direction moving mechanism which closely_contact | adheres a part to the side surface of a to-be-packaged object, it can be reliably made to adhere to the side of the to-be-packaged object with the form accompanying the linear descent | fall operation | movement.

また、幅方向移動機構は、一部を下方に移動する基体に枢支されて揺動側に第２点当たり把持手段を有する揺動部材と、該揺動部材を幅方向内側に対して進退駆動させる駆動手段と、を含む構成であるから、帯フィルムの両側を把持した状態のままで、直線的に下降させ、さらにその際に帯フィルムの糊付け部を被包装物の側面側への接着動作をコンパクトで簡単な構成により、確実に実行させ得る。   Further, the width direction moving mechanism includes a swinging member that is pivotally supported by a part of the base body that moves downward, and has a gripping means for the second point on the swinging side, and the swinging member is moved forward and backward with respect to the widthwise inner side. And driving means for driving, so that the both sides of the belt film are held in a straight line, and the belt film is glued to the side of the package to be packaged. The operation can be reliably executed with a compact and simple configuration.

本発明のフィルム包装装置は、フィルムロールから繰り出されるフィルムを挟持搬送する搬送部と、搬送部から送られてきたフィルムを所定幅長さに切断する切断部と、切断された帯フィルムの両端側を把持した状態で被包装物に被せ動作させる被せ動作部と、被せ動作部の被せ動作位置を含む供給ラインに被包装物を供給する被包装物供給部と、を備え、フィルムの両端側を点当たり状に押圧、解放自在に把持しつつ搬送部と協働してフィルムを被せ動作部側に搬送補助する第１点当たり把持手段を含む。第１点当たり把持手段は、フィルムの両端側を点当たり状に押圧、解放自在に把持しつつ、搬送部の搬送補助を行うものであり、フィルムを点当たり状に挟んで把持するから基本的にはいずれかが平面で他方が点当たり素材から構成される場合が多い。たとえば上下のいずれかの面が平面で他方の面が点当たり素材の構成であるとよい。点当たり素材は、転動体が好ましい。球体であればそれ自体で自在転動を行うので製造が容易である点からより好ましい。球体は鋼球、硬質合成樹脂、セラミック、その他任意の素材を選択してよい。なお、点当たり素材としては、厳密な意味での点での接触を行わないものも含む。たとえば、立体楕円、回転放物面体などでもよい。点当たり状に押圧、解放自在に把持しうる構成であれば任意でよく、たとえば球体を直列状に配置したもの、その他、規則的な配置あるいは不規則な配置のいずれの配置構成で転動体を支持した構成で受けるようにしてもよい。本発明のフィルム包装装置は、被包装物へのフィルム帯び掛け包装を行うものであり、フィルムは、表裏いずれかの面に糊付けが施されたものでも、搬送途中に糊付けを行ってフィルムロールからの繰り出し時にはまだ糊付けされていないものでもよい。本装置では特に、糊付けがされてロール状に巻回された状態のものを繰り出し搬送する場合に特に効果的である。なお、点当たり把持手段は、たとえば転動体と転動体との挟持による場合でもよい。   The film packaging apparatus of the present invention includes a transport unit that sandwiches and transports a film fed from a film roll, a cutting unit that cuts the film sent from the transport unit into a predetermined width, and both ends of the cut strip film A covering operation part that covers the object to be packaged in a state where the object is gripped, and a packaged object supply part that supplies the object to be packaged to a supply line including a covering operation position of the covering operation part. It includes a first point hitting means that covers the film in cooperation with the transport unit while pressing and releasing in a point-scoring manner so as to assist the transport to the operation unit side. The first point-scoring means is for assisting the transport of the transport unit while pressing and releasing the both end sides of the film in a point-scoring manner so that the film is sandwiched in a point-scoring manner. In many cases, one of them is a flat surface and the other is made of a material with points. For example, one of the upper and lower surfaces may be a flat surface and the other surface may be a dot-scoring material. The point hitting material is preferably a rolling element. If it is a spherical body, it is more preferable from the viewpoint of easy manufacture because it rolls on its own. As the sphere, a steel ball, hard synthetic resin, ceramic, or any other material may be selected. It should be noted that the point hitting material includes those that do not make contact at a point in a strict sense. For example, a solid ellipse or a rotating paraboloid may be used. Any configuration can be used as long as it can be pressed and released freely in a spot-like manner. For example, the rolling elements can be arranged in either a regular arrangement or an irregular arrangement in which spheres are arranged in series. You may make it receive in the structure which supported. The film wrapping apparatus of the present invention performs film wrapping and wrapping on an article to be wrapped. Even if the film is glued on either the front or back side, the film is glued in the middle of transporting from the film roll. It may be one that has not been glued at the time of feeding. This apparatus is particularly effective when feeding and transporting a state of being glued and wound into a roll. The point hitting means may be, for example, a case where the rolling elements are sandwiched between the rolling elements.

被せ動作部は、帯フィルムの両端側を点当たり状に押圧、解放自在に把持する第２点当たり把持手段を含むとよく、特に、糊付け状態の帯フィルムの両端を把持した状態で、これを被包装物の上面に帯び掛けする際には、点当たり部分での糊付着部分を簡単かつ円滑に離脱させうるから有効である。   The covering operation part may include a second point-scoring means for pressing and releasably pressing both ends of the belt film in a spot-like manner, particularly in a state where both ends of the belt film in the glued state are gripped. When applying to the upper surface of the article to be packaged, it is effective because it is possible to easily and smoothly remove the glue-attached portion at the spot-contact portion.

また、第１点当たり把持手段は、搬送されるフィルムの両端側において直列状に配置させそれぞれが自由転動自在に設けた複数の球体と、該複数の球体の頂点を含む面に搬送されるフィルムの両端側を位置させてその上面から押さえ、退避自在に設けられた押さえフレームと、を含むときわめて簡単な球体の保持構成でかつ、効果的にフィルム両端の点当たり把持離脱を行わせる。球体の直列配置構成は単列でも複数列でもよい。この点は、第２点当たり把持手段の場合でも同様である。すなわち、第２点当たり把持手段は、帯フィルムの両端側において直列状に配置保持させそれぞれが自由転動自在に設けた複数の球体と、該複数の球体の頂点を含む面に帯フィルムの両端側を位置させてその上面から押さえ、退避自在に設けられた第２押さえフレームと、を含むようにしてもよい。第１点当たり把持手段の押圧、解放自在の駆動構成は、転動体側を固定として押さえフレーム側を可動としても、あるいは押さえフレーム側を固定として転動体側を可動として押圧、解放動作を行うようにしてもよい。   Further, the gripping means for the first point is transported to a surface including a plurality of spheres arranged in series on both end sides of the film to be transported, each provided so as to freely roll and a vertex including the vertices of the plurality of spheres. When both ends of the film are positioned and pressed from the upper surface of the film, a holding frame provided so as to be retractable is included, so that the holding structure of the sphere can be held very easily, and the film can be effectively held and released at points. The series arrangement of the spheres may be a single row or a plurality of rows. This is the same for the gripping means for the second point. That is, the gripping means for the second point is arranged and held in series on both end sides of the band film, and each of the two ends of the band film is provided on a surface including the vertices of the plurality of spheres. And a second presser frame that is provided so that the side is positioned and pressed from the upper surface thereof so as to be retractable. The drive mechanism capable of pressing and releasing the gripping means at the first point performs the pressing and releasing operation with the rolling element side fixed and the pressing frame side fixed, or the pressing frame side fixed and the rolling element side movable. It may be.

さらに、被せ動作部は、被包装物供給部の供給ライン上に設定された被せ動作位置を有し、被せ動作部は、帯フィルムの両端側を把持した状態で下方へ移動させることにより被包装物への帯フィルムの被せ動作を行い、その際、帯フィルムの両端側を対向内側方向に押さえて糊付け部を被包装物の側面側に密着させる幅方向移動機構を有するとよい。   Further, the covering operation part has a covering operation position set on the supply line of the package supply part, and the covering operation part is moved downward by gripping both end sides of the belt film. It is good to have the width direction moving mechanism which performs the covering operation | movement of the strip film to a thing, presses the both ends side of a strip film in the opposing inner side direction, and closely_contact | adheres the gluing part to the side surface side of a package.

That is, point-scoring by the first-pointing gripping mechanism 30, central gripping transport by the transport unit 12, release of gripping by the first point, advance by the transport unit 12, stop of the upper and lower transport frames 261, 262 at the forward end position (see FIG. 5), gripping on the film transport end side by the first and second point holding mechanism and the front side of the covering operation part 16 (see FIG. 4 and FIG. 6), and cutting by the heated metal wire 142, covering operation The standby state. At this time, when the detection sensor 87 detects the article M that is intermittently fed by the conveyor 66 of the article supply unit 20, the conveyor 66 returns to the return position for one stroke and waits and stops. The gripping mechanism 40 that holds the second film for cutting and holding the film as the belt film 510 is lowered and covers the both ends of the band film with the both-side glued portions 505 from above and below.

すなわち、図１１において、被せ動作Ｂでは、まず第１上下駆動機構４８の第１上下動シリンダ４８１が駆動して連結板５６を介して両側の揺動アーム４６を下降させる（下降１回目）（Ｓ１０）。このとき、揺動アーム４６の上端のローラ１０１が変向部材１０２に接触して揺動アームが下降するに従って徐々に下端側、すなわちフィルムの把持側を内側に変向させる動きを行い、図７に示すように両揺動アーム４６が逆ハ字状に変位する。この動きによって、樹脂ケースＭＣの上面から適正に被せる位置を準備する。次に、幅方向移動機構４２の幅移動シリンダ４２１が駆動し、アーム４６の下端側を内側に移動させて揺動アーム４６の下端側を樹脂ケースＭＣの側面に押し付け（アーム幅寄せ）（Ｓ１１）、さらに、第２両端押さえシリンダ５４を駆動させて球体を保持する保持ケース５８側を引き下げて開放し（フィルム放す）（Ｓ１２）、帯フィルムの両端側を第２点当たり把持部の拘束から離脱させる（図８参照）。この状態で、次に第２上下駆動機構の第２上下動シリンダ５０１を駆動させさらに下降させる（下降２回目）（Ｓ１３）。このとき、揺動アームの下端側によって帯フィルムの糊付け部が樹脂ケースＭＣの側面に押し付けられた状態で引き下げられるので、帯フィルムの糊付け部において確実に樹脂ケースに接着され帯掛けが完了する。この後、幅移動シリンダ４２１のロッドが伸長復帰して揺動アーム４６の下端側が開き（アーム幅開き）（Ｓ１４）、それぞれ第１、第２上下動シリンダ４８１，５０１が逆の駆動により２回上昇し（Ｓ１５）、揺動アーム下端側の第２点当たり把持機構４０によるアーム下端側底部４６１と保持ケース５８により転動自在に保持される球体頂部とにフィルムの挿入空隙を開いた状態でその挟持待機位置に復帰する。そして、搬送部１２によりフィルムが搬送されてその前進端側の糊付け部５０５を含む両端側が第２点当たり把持部の間隙に挿入されたときに、それぞれ第１点当たり把持機構とともに、第２点当たり把持機構４０による把持がなされ（Ｓ１６）、搬送部側でのフィルムの切断後、帯フィルムの両端把持状態での下降動作を行い先のＳ１０〜Ｓ１６を繰り返す。   That is, in the covering operation B in FIG. 11, first, the first vertical movement cylinder 481 of the first vertical drive mechanism 48 is driven to lower the swing arms 46 on both sides via the connecting plate 56 (first drop) ( S10). At this time, as the roller 101 at the upper end of the swing arm 46 comes into contact with the deflecting member 102 and the swing arm descends, the lower end side, that is, the gripping side of the film is gradually moved inward. As shown in FIG. 2, both swing arms 46 are displaced in an inverted C shape. By this movement, a position for appropriately covering from the upper surface of the resin case MC is prepared. Next, the width moving cylinder 421 of the width direction moving mechanism 42 is driven, the lower end side of the arm 46 is moved inward, and the lower end side of the swing arm 46 is pressed against the side surface of the resin case MC (arm width adjustment) (S11). ) Further, the second end holding cylinder 54 is driven to lower and release the holding case 58 side holding the sphere (release the film) (S12). Separate (see FIG. 8). In this state, the second vertical movement cylinder 501 of the second vertical drive mechanism is then driven and further lowered (second drop) (S13). At this time, the band film glued portion is pulled down by the lower end side of the swing arm while being pressed against the side surface of the resin case MC, and the band film glued portion is securely adhered to the resin case and the banding is completed. Thereafter, the rod of the width moving cylinder 421 expands and returns to open the lower end side of the swing arm 46 (arm width opening) (S14), and the first and second vertically moving cylinders 481 and 501 are driven twice by reverse driving. Ascending (S15), with the film insertion gap open at the bottom end 461 of the arm lower end by the gripping mechanism 40 on the lower end side of the oscillating arm and the top of the sphere movably held by the holding case 58 Return to the holding standby position. When the film is transported by the transport unit 12 and the both end sides including the glued portion 505 on the forward end side are inserted into the gaps of the gripping portion at the second point, the second point is obtained together with the gripping mechanism at the first point. The gripping mechanism 40 grips the film (S16), and after the film is cut on the conveying unit side, the belt film is lowered in the gripping state at both ends, and steps S10 to S16 are repeated.

一方、フィルム搬送部１２側（Ａ）では第１点当たり把持機構３０の直列配置された複数球体３４上面にフィルム両端を載置させた状態で上から押さえフレーム３６により複数の自由転動球体による点接触で押さえて挟みこみ（Ｓ２０）フィルムの両端側の動きを概略拘束しその状態で上下搬送フレーム２６１，２６２によりフィルムの中央側を挟持する（Ｓ２１）。その後、再び両端の第１点当たり把持機構３０を解放し（Ｓ２２）、その状態で中央側のフィルム挟持部分（２６）を前進させる（Ｓ２３）。搬送駆動機構２８の駆動モータ２８４による所定ストローク幅の前進送り位置で中間にフィルムを挟む上下搬送フレーム２６１，２６２が停止し（Ｓ２４）、その状態では待機する揺動アーム４６の下端側の第２点当たり把持部の挿入間隙内にフィルムの両端側が突入した状態にある。この状態で、再び第１点当たり把持機構の押さえフレーム３６が下降押圧してフィルム繰り出し側を挟む（Ｓ２５）とともに、先の被せ動作部（Ｂ）の第２点当たり把持機構（Ｓ１７）がフィルムの先端側を把持し、この状態でそのフィルム長さ中間位置で加熱された金属線条１４２が上昇して所定長さでフィルムを溶断し（Ｓ２６）、帯フィルム５１０を作成する。作成された帯フィルムは先の述べたＳ１０〜Ｓ１６の工程を行うことにより被包装物に対する帯フィルムの帯掛け動作を連続しておこなうとともに、搬送部側では、フィルムの溶断後、上下搬送フレーム２６１，２６２が開放し（Ｓ２７），フィルム繰り出し基端側に後退し（Ｓ２８）、図１の位置に復帰して停止し（Ｓ２９）、以下Ｓ２１からＳ２６のフィルムの挟持、搬送、フィルム溶断までを繰り返し行い、被包装物供給部２０の被包装物をセンサ８７が検出すると、次工程以降繰り返す動作を行う。   On the other hand, on the film transport unit 12 side (A), a plurality of free rolling spheres are formed by a pressing frame 36 from above in a state where both ends of the film are placed on the upper surfaces of the plurality of spheres 34 arranged in series of the first point-holding mechanism 30. Holding by point contact and pinching (S20), the movement of both ends of the film is roughly restricted, and in this state, the center side of the film is pinched by the upper and lower transport frames 261 and 262 (S21). Thereafter, the gripping mechanism 30 for the first point at both ends is released again (S22), and the central film clamping portion (26) is advanced in this state (S23). The upper and lower transport frames 261 and 262 sandwiching the film in the middle at the forward feed position of a predetermined stroke width by the drive motor 284 of the transport drive mechanism 28 are stopped (S24), and in this state, the second on the lower end side of the swinging arm 46 waiting. The film is in a state where both end sides of the film have entered into the insertion gap of the point-holding part. In this state, the holding frame 36 of the holding mechanism for the first point descends again to pinch the film feeding side (S25), and the holding mechanism (S17) for the second point of the previous operating portion (B) is the film. In this state, the metal wire 142 heated at the middle position of the film length rises and the film is melted by a predetermined length (S26), and the belt film 510 is formed. The produced band film continuously performs the banding operation of the band film on the package by performing the steps S10 to S16 described above, and on the conveyance side, after the film is melted, the upper and lower conveyance frames 261 are provided. , 262 is opened (S27), retreats to the film delivery base end side (S28), returns to the position shown in FIG. 1 and stops (S29), and thereafter, from S21 to S26, film clamping, conveyance, and film fusing. Repeatedly, when the sensor 87 detects the object to be packaged in the object to be packaged supply unit 20, the operation is repeated after the next process.

以上説明したように、実施形態のフィルム包装装置では、フィルムの両端側を点当たり状に押圧、解放自在に把持しつつフィルムを被せ動作部側に搬送補助する第１点当たり把持手段を含むから、フィルムロールから繰り出され搬送されるフィルムの搬送前後のフィルム両端の仮押さえを糊付け部そのものに直列状の鋼球の頂部を押し付けた状態で行う結果、押さえ部分が簡単にずれたり、離脱することがないとともに、押さえフレームを離脱させるときには糊付け部が下部の支持部分に貼り付いてしまうことがなく外れ、搬送部により確実に搬送しうる。さらに、帯フィルムの両端側を点当たり状に押圧、解放自在に把持する第２点当たり把持手段を含むから特に、直列状配置の複数球体構成だと軸受部分が不要であり、よって、軸方向設定が不要で球体を保持する保持ケースの構成が極めて簡単となり、製造が簡単で低コストを実現し得る上に、球体からのフィルムの離脱も容易に行われフィルムのめくり上げや巻き付き貼着がなくて作業中断の少ない安定し連続の帯掛け動作を継続して行うことができる。   As described above, the film wrapping apparatus according to the embodiment includes the first point-scoring means that covers the film while pressing the both end sides of the film in a spot-like manner, and covers the film while it is releasably supported. As a result of the temporary pressing of both ends of the film before and after the conveyance of the film fed out from the film roll being performed with the top of the steel ball in series pressed against the gluing part itself, the pressing part can be easily displaced or detached. In addition, when the presser frame is released, the glued part is not stuck to the lower support part and can be reliably conveyed by the conveying part. In addition, since it includes a second point hitting means that presses both end sides of the belt film in a spot-like manner and releasably holds, the bearing portion is not required particularly in the case of a multi-sphere arrangement in a series arrangement, and therefore the axial direction The configuration of the holding case that holds the sphere is unnecessary because it does not require setting, and it can be manufactured easily and at low cost. In addition, the film can be easily detached from the sphere, so that the film can be turned up and wound. Therefore, stable and continuous banding operation can be continuously performed with less work interruption.
