Description

【０００１】
【発明の属する技術分野】
本発明は、ナス、キュウリ、ほうれん草などの蔬菜類、果物類、花卉あるいは鉢植え草花などを包装袋で包装する際に使用する包装用補助具に関する。
【０００２】
【従来の技術】
スーパーマーケットなどにおいて販売されている蔬菜類や果物などは、一般に適当な個数をポリエチレンなどの合成樹脂フィルム製の包装袋に入れ、袋上部を粘着テープで縛るか、熱融着することによって封止した状態で陳列されている。通常、このような包装袋への包装作業は、蔬菜類や果物などを生産者から集荷し、スーパーマーケットなどに納入するまでの過程において行われている。
【０００３】
これらの包装作業は、その取扱量が多い場合は自動包装機で行われ、取扱量が少ない場合は手作業で行われているが、手作業による包装過程においては、被包装物を袋に入れる際の作業性を高めるため、漏斗形状の包装用補助具が使用されている。
【０００４】
漏斗形状をした包装用補助具を用いて包装作業を行う場合、包装用補助具の下方の細径部分を包装袋の上縁開口部から袋内へ挿入し、この状態で当該補助具上面の擂鉢状開口部から被包装物を投入し、細径部の内周面に沿って滑落させることによって被包装物を袋内へ詰め込んでいる。
【０００５】
【発明が解決しようとする課題】
従来の包装用補助具の場合、細径部分を包装用袋内へ挿入して包装作業開始状態にセットする際の作業性を考慮すると、当該細径部分の外径をなるべく細くすることが望ましい反面、擂鉢状開口部に投入された被包装物を傷つけることなく円滑に包装袋内へ誘導するには、包装袋内へ挿入される細径部分の内径をなるべく大きくすることが望ましいのであるが、一つの包装用補助具でこれらの相反する要請を共に満たすことは極めて困難である。
【０００６】
また、従来の包装用補助具は、被包装物を包装袋内へ誘導する細径部分の内径がほとんど一定であるため、ナスやキュウリなどのように太さが不均一なもの、ほうれん草などのように葉部分が広がった形状のものあるいは果実類のように球体に近い形状のものなどは、細径部分内をスムーズに通過しないことがある。
【０００７】
本発明が解決しようとする課題は、包装袋への着脱が容易で、被包装物を円滑に包装袋内へ導入することのできる包装用補助具を提供することにある。
【０００８】
【課題を解決するための手段】
本発明の包装用補助具は、包装袋の開口部に誘導部材の終端部を挿入し、前記誘導部材の始端部を前記開口部から露出させた状態で当該包装袋に着脱可能にセットし、前記誘導部材に当接させた被包装物を前記誘導部材に沿って前記始端部から前記終端部に向かう誘導方向へ押圧するか自然落下させることより前記被包装物を前記包装袋内へ導入する包装用補助具であって、
被包装物を前記誘導方向へ誘導するための平面状の誘導部を有する平板状の誘導部材、曲面状の誘導部を有する曲面板状の誘導部材、直線状の誘導部を有する直線状の線材で形成された誘導部材または曲線状の誘導部を有する曲線状の線材で形成された誘導部材を漏斗形状または筒状をなすように複数配列し、複数の前記誘導部材を、少なくとも前記誘導方向の終端部が互いに接近離隔移動可能な状態に連結して形成し、さらに、前記誘導部材の始端部をそれぞれ前記漏斗形状部分または前記筒状部分の外周方向へ折曲させることにより前記包装袋内に挿入された前記誘導部よりも拡径した鍔部分を形成したことを特徴とする。
【０００９】
このような構成とすることにより、当該包装用補助具を構成する複数の誘導部材の終端部はそれぞれ拡径方向、縮径方向へ移動可能となるため、包装用補助具を包装袋にセットするときは、その誘導方向の終端部を縮径させることで包装袋内へ容易に挿入することができ、被包装物を包装袋内へ誘導するときは被包装物との接触で誘導部材が拡径方向に移動して包装袋を広げるので、被包装物を円滑に包装袋内へ導入することができるようになる。また、被包装物を包装袋内へ誘導し終わった後、包装用補助具を包装袋から抜き取るときも、包装袋と被包装物の状態に応じて誘導部材の終端部が拡径、縮径可能であるため、包装袋からの離脱も容易である。
【００１０】
ここで、複数の前記誘導部材の連結手段として、隣接する誘導部材同士を傾動自在に連結する支軸またはヒンジを設ければ、比較的小さな力で誘導部材の誘導方向の終端部を互いに接近離隔移動させることができるようになるため、包装袋への着脱性および被包装物の導入機能がさらに向上し、当該包装用補助具内を通過する被包装物に損傷を与えることなく包装袋内へ誘導することができるようになる。
【００１１】
前述したように誘導部材同士を傾動自在に支軸で連結した場合、誘導部材の誘導方向の終端部が拡径方向へ移動すると、これに伴って誘導部材の支軸より上の部分が縮径方向へ移動するため、包装用補助具の開口部が狭くなって被包装物の誘導機能が低下することがある。そこで、支軸を誘導部材の誘導方向の始端部に接近させて配置すれば、誘導部材の終端部の拡径移動に伴って縮径する範囲（誘導部材の支軸より上の部分）を縮小することができるため、開口部が狭まることによる誘導機能の低下を抑制することができる。
【００１２】
この場合、支軸が配置された部分を除く誘導部材の始端部を、その終端部方向へ湾曲させたり、切欠したりした形状あるいは外周方向へ折曲した形状とすれば、誘導部材の終端部の拡径移動に伴って縮径する始端部分をさらに縮小することができるため、誘導機能の低下を抑制する効果が高まる。
【００１３】
前記誘導部材として、平面状誘導部材と、前記平面状誘導部材に凹面を向けて配列された樋状誘導部材とを用いれば、当該包装用補助具内に断面が蒲鉾形状の誘導経路が形成されるため、開口部を上にした包装袋を垂直支持板の表面に吊下げた状態で包装作業を行う場合の使用に適したものとなり、吊下げ状態の包装袋へ被包装物を円滑に導入することができるようになる。
【００１４】
すなわち、垂直支持板の表面に吊下げられた包装袋は当該垂直支持板方向へ広げることができないが、前記平面状誘導部材が垂直支持板に面するようにして当該包装用補助具の終端部を包装袋内へ挿入すれば、樋状誘導部材の終端部を垂直支持板のない方向へ移動させることで包装袋を広げることが可能となるため、前記吊下げ状態の包装袋内のように、誘導部材の終端部が全周方向に拡径移動できない場合に適したものとなり、この場合においても被包装物を包装袋内へ円滑に導入することができる。
【００１５】
ここで、前記樋状部材の樋底部を、被包装物の誘導方向に従って平面状誘導部材に接近した形状とすれば、誘導部材の終端部側を薄小化することができるので、包装袋内への挿入性および被包装物導入後の包装袋からの離脱性を高めることができる。この場合、樋状部材の樋底部を平面状誘導部材に接近する形状としては、被包装物の性状に応じて、直線的に接近する形状、曲線的に接近する形状などを採用することができる。
【００１６】
また、前記誘導部材の少なくとも一つを、被包装物の誘導方向に従って幅を縮小したテーパ形状とすれば、誘導部材の終端部側をさらに近く接近移動させ、小さく縮径させることが可能となるため、包装袋内への挿入性および被包装物導入後の包装袋からの離脱性を高めることができる。
【００１７】
【発明の実施の形態】
図１は本発明の第一実施形態である包装用補助具を斜め上方から見た状態で示す斜視図、図２は図１に示す包装用補助具を斜め下方から見た状態で示す斜視図、図３および図４は図１に示す包装用補助具を用いた包装作業を示す説明図である。
【００１８】
図１，図２に示すように、本実施形態の包装用補助具１は、被包装物を一定方向へ誘導するための平面状の誘導部２ａを有する８個の誘導部材２を漏斗形状に配列し、これらの誘導部材２を、リング状の支軸３により、その誘導方向の終端部２ｂが互いに接近離隔移動可能な状態に連結して形成している。８個の誘導部材２は支軸３を中心に傾動自在であるため、各誘導部材２の終端部２ｂは拡径方向、縮径方向へ移動自在である。
【００１９】
包装用補助具１を用いて包装作業を行う場合、図３（ａ）に示すように、開口部５ａを上にして垂直支持板４に吊下げ状態に保持された包装袋５の開口部５ａに、包装用補助具１の誘導部材２の終端部２ｂを窄めた状態にして挿入する。このとき、各誘導部材２の終端部２ｂは互いに接近して最も縮径した状態にあるため容易に挿入することができる。また、各誘導部材２の始端部２ｃをそれぞれ外周方向へ折曲させることにより、誘導部２ａよりも拡径した鍔部分を形成しているため、包装用補助具１が包装袋５内へ落下することもない。
【００２０】
この後、図３（ｂ）に示すように、被包装物である複数のナスＮを略垂直状態に束ねて包装用補助具１内へ差し込むと、束になったナスＮの一部が誘導部材２の誘導部２ａに当接して誘導部材２を外周方向へ押圧し、図３（ｃ）に示すように、各誘導部材２の終端部２ｂが拡径するため、ナスＮを自然落下させるかあるいは軽く押し下げるかするだけで、ナスＮを円滑に包装袋５内へ導入することができる。この場合、支軸３は誘導部材２の始端部２ｃに接近させて配置されているため、誘導部材２の終端部２ｂが拡径方向へ移動しても、始端部２ｃが大幅に縮径して誘導機能を阻害することはない。
【００２１】
図４（ａ）に示すようにナスＮが包装袋５内へ導入されたら、包装用補助具１を包装袋５から取り外した後、ナスＮの入った包装袋５のみを下方へ引っ張って垂直支持板４から当該包装袋５を離脱させ、開口部５ａの下方を粘着テープ６などで結束し、開口部５ａ付近の余剰部分５ｂを切断除去すれば、包装作業が完了する。
【００２２】
ナスＮの導入が終わった包装袋５から包装用補助具１を取り出す場合、包装袋５およびナスＮの状況に応じて、誘導部材２の終端部２ｂがそれぞれ自由に拡径、縮径可能であるため、包装袋５からの離脱も容易である。包装袋５から離脱させた包装用補助具１は、図４（ｂ）に示すように垂直支持板４に吊下げられている空の包装袋５の開口部ａから袋内へ挿入すれば、前述した手順で次の包装作業を行うことができる。
【００２３】
包装用補助具１は８個の誘導部材２を備えているため、被包装物を導入するとき包装袋５をほぼ全周方向へ広げることができる点で優れている。包装用補助具１の用途は特に限定しないが、比較的硬くて丸い物品あるいはスリップ性が良好で長い物品などを包装袋５内へ導入する場合に好適である。また、包装用補助具１を包装袋５にセットした状態において、包装用補助具１内を通して包装袋５内へ手を差し込むようにして包装作業を行ったり、包装袋５内へ手を差し込んで被包装物の整列を行ったりすることもできるため、利便性に優れている。
【００２４】
次に図５，図６を参照して本発明の第二実施形態である包装用補助具１１について説明する。図５に示すように、包装用補助具１１は、凹曲面状の誘導部１２ａを有する二つの誘導部材１２を、それぞれの凹曲面同士を対向させて漏斗形状に配置し、二つの誘導部材１２同士を柔軟で折り曲げ自在なヒンジ１３で連結して形成している。
【００２５】
したがって、図６に示すように、包装用補助具１１の二つの誘導部材１２は、ヒンジ１３を中心にして、その誘導方向の終端部１２ｂが互いに接近離隔移動する方向へ傾動可能であり、これによって、終端部１２ｂが拡径、縮径するように移動する。
【００２６】
包装用補助具１１の使い方は、前述した包装用補助具１と同じであり、同様の機能、効果が得られるが、包装用補助具１１を構成する誘導部材１２は二つであるため、製作が簡単であるほか、二つの誘導部材１２の終端部１２ｂ同士を密着させるだけで下端部１２ｂ付近は最小化するので包装袋５内への挿入が容易である点が優れている。また、包装用補助具１１の用途は特に限定するものではないが、比較的硬くて丸い物品あるいはスリップ性が良好で長い物品などのほか軟らかい物品を包装袋５内へ導入する場合に好適である。
【００２７】
次に図７，図８を参照して本発明の第三実施形態である包装用補助具２１について説明する。図７に示すように、本実施形態の包装用補助具２１は、平面状誘導部２２ａを有する平板状の誘導部材２２と、この誘導部材２２に凹面状誘導部２３ａを向けて配列した樋状誘導部材２３とを、支軸２４で傾動自在に連結することによって形成している。したがって、樋状誘導部材２３の終端部２３ｂは誘導部材２２に接近離隔移動可能である。
【００２８】
包装用補助具２１においては、図７（ｃ）に示すように、包装用補助具２１内に断面が蒲鉾形状の誘導経路２４が形成されるため、図８に示すように、開口部５ａを上にした包装袋５を垂直支持板４の表面に吊下げた状態で包装作業を行う場合の使用に適している。
【００２９】
図８に示すように、垂直支持板４の表面に吊下げられた包装袋５は垂直支持板４方向へ広げることができないが、平板状の誘導部材２２が垂直支持板４に面するようにして包装用補助具２１の終端部を包装袋５内へ挿入すれば、樋状誘導部材２３の終端部２３ｂを垂直支持板４のない方向へ移動させることによって包装袋５を広げることが可能となる。したがって、吊下げ状態の包装袋５内のように、誘導部材２２の終端部が垂直支持板４に向って拡径移動できない場合の包装作業に適しており、この場合においても被包装物であるほうれん草Ｈを包装袋５内へ円滑に導入することができる。
【００３０】
包装用補助具２１においては、図７（ｂ）に示すように、誘導部材２２および樋状誘導部材２３の幅を被包装部の誘導方向に沿って縮小したテーパ形状とするとともに、図７（ａ）に示すように、樋状誘導部材２３の樋底部２３ｃを被包装物の誘導方向に従って誘導部材２２方向へ直線的に接近させた形状としているため、終端部２３ｂ付近を小さく縮径させることで包装袋５内へスムーズに挿入することができる。
【００３１】
また、誘導部材２２の始端部を樋状誘導部材２３の始端部より延設することにより、包装用補助具２１の全体が状差し形状となっているため、包装袋５内への被包装物の導入を極めて円滑に行うことができる。そのほか、包装用補助具２１は、包装用補助具１，１１よりも比較的長い誘導部材２２および樋状誘導部材２３を備えているため、包装袋の底付近まで開くことができる点で優れており、スリップ性の悪い比較的長い物品や比較的軟らかくて丸い物品を包装袋に導入する包装作業に好適である。
【００３２】
次に図９を参照して本発明の第四実施形態である包装用補助具３１について説明する。図９に示すように、本実施形態の包装用補助具３１は、平面状誘導部３２ａを有する平板状の誘導部材３２と、これより幅の狭い平面状誘導部３３ａを有する４枚の平板状の誘導部材３３とを略五角筒形状をなすように配列し、誘導部材３２，３３の始端部付近を支軸３４で傾動自在に連結している。誘導部材３３の支軸３４より上方に位置する部分は外側へ折り曲げた形状となっている。
【００３３】
包装用補助具３１の使い方は、図８に示す包装用補助具２１と同様であり、同様の機能、効果を得ることができるが、包装用補助具３１の場合、４枚の平板状の誘導部材３３を備えており、包装袋を４方向へ開くことができるため、葉物野菜などのように広がった形状の物品の包装作業に好適である。
【００３４】
次に図１０，図１１を参照して本発明の第五実施形態である包装用補助具４１について説明する。包装用補助具４１は、図１０に示すように、平面状誘導部４２ａを有する角樋形状の誘導部材４２と、凹曲面形状の誘導部４３ａを有する樋状誘導部材４３とを筒状をなすように対向配置し、支軸４４で傾動自在に連結して形成し、誘導部材４２の終端部４２ｂと樋状誘導部材４３の終端部４３ｂとは互いに接近離隔移動可能である。樋状誘導部材４３の樋底部４３ｄは、被包装物の誘導方向に従って誘導部材４２方向へ曲線的に接近させた形状としている。
【００３５】
包装用補助具４１においては、樋状誘導部材４３の始端部４３ｃを終端部４３ｂ方向へ湾曲させた形状としているため、終端部４２ｂ，４３ｂを離隔方向へ移動させたとき、樋状誘導部材４３の始端部４３ｃが図１０（ｂ）の仮想線Ｓで示すように誘導部材４２方向に近づくことがないので、開口部の縮径によって包装作業が阻害されることがない。
【００３６】
包装用補助具４１は、前述と同様、図１１に示すように垂直状態に吊下げられた包装袋５に挿入してほうれん草Ｈなどの包装作業を行うことができ、この場合においても、前述した包装用補助具２１，３１などと同様の機能、効果を得ることができる。
【００３７】
包装用補助具４２においては、樋状誘導部材４３の樋底部４３ｄは、その終端部４３ｂに向うに従って誘導部材４２方向へ曲線的に接近させた形状としているため、図１１（ｂ）に示すように、包装袋５内へほうれん草Ｈを導入した後、包装用補助具４１を包装袋５から取り出すとき、包装用補助具４１を上方へ引っ張れば、樋底部４３ｄの中央部分Ｘ付近がほうれん草Ｈの葉部などを内側へ押さえ込むとともに、終端部４３ｂが包装袋５を外側へ押し広げるので、取り出しが極めて容易である。
【００３８】
【発明の効果】
本発明により、以下の効果を奏する。
【００３９】
（１）包装袋の開口部に誘導部材の終端部を挿入し、前記誘導部材の始端部を前記開口部から露出させた状態で当該包装袋に着脱可能にセットし、前記誘導部材に当接させた被包装物を前記誘導部材に沿って前記始端部から前記終端部に向かう誘導方向へ押圧するか自然落下させることより前記被包装物を前記包装袋内へ導入する包装用補助具において、

【００４１】
（３）前記支軸を誘導部材の始端部に接近させて配置すれば、誘導部材の終端部の拡径移動に伴って縮径する範囲（誘導部材の支軸より上の部分）を縮小することができるため、開口部の狭まりに起因する誘導機能の低下を抑制することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a packaging aid used when packaging sugar beet such as eggplant, cucumber, spinach, fruits, flowers, potted plants and the like in a packaging bag.
[0002]
[Prior art]
Prepared items such as sugar beet and fruits sold in supermarkets are generally sealed in a packaging bag made of a synthetic resin film such as polyethylene, and the upper part of the bag is tied with adhesive tape or heat-sealed. Displayed in state. Usually, the packaging operation in such a packaging bag is performed in the process from picking up vegetables and fruits from the producer to delivery to a supermarket or the like.
[0003]
These packaging operations are performed by automatic packaging machines when the handling amount is large, and are manually performed when the handling amount is small. In the manual packaging process, the items to be packaged are put in a bag. In order to improve workability, funnel-shaped packaging aids are used.
[0004]
When packaging is performed using a funnel-shaped packaging aid, the lower diameter portion of the packaging aid is inserted into the bag from the upper edge opening of the packaging bag, and in this state, The article to be packaged is put into the bag by inserting the article to be packaged from the bowl-shaped opening and sliding it along the inner peripheral surface of the small-diameter portion.
[0005]
[Problems to be solved by the invention]
In the case of conventional packaging aids, it is desirable to reduce the outer diameter of the small-diameter portion as much as possible in consideration of workability when inserting the small-diameter portion into the packaging bag and setting the packaging operation start state. On the other hand, it is desirable to increase the inner diameter of the small-diameter portion inserted into the packaging bag as much as possible in order to smoothly guide it into the packaging bag without damaging the article to be packaged in the bowl-shaped opening. It is very difficult to meet these conflicting requirements together with a single packaging aid.
[0006]
In addition, since conventional packing aids have an almost constant inner diameter of the small diameter portion that guides the packaged item into the packaging bag, such as eggplant and cucumber, etc., with uneven thickness, such as spinach In the case where the leaf portion has a shape that expands like this, or the shape that is close to a sphere like a fruit, the portion inside the small diameter portion may not pass smoothly.
[0007]
The problem to be solved by the present invention is to provide a packaging aid that can be easily attached to and detached from a packaging bag and can smoothly introduce an article to be packaged into the packaging bag.
[0008]
[Means for Solving the Problems]
The packaging auxiliary tool of the present invention inserts the terminal end portion of the guide member into the opening portion of the packaging bag, and is detachably set to the packaging bag with the starting end portion of the guide member exposed from the opening portion. The article to be packaged is introduced into the packaging bag by pressing the article to be packaged in contact with the guide member along the guide member in the guide direction from the start end portion toward the end portion or by letting it naturally drop. A packaging aid,
A flat plate-like guide member having a flat guide portion for guiding the package in the guide direction, a curved plate-like guide member having a curved guide portion, and a linear wire having a straight guide portion arranging a plurality induction member formed of a curved shaped wire having in guide member is formed or curved guiding portion so as to form a funnel-shaped or cylindrical, a plurality of said guide member, at least the guidance direction In the packaging bag, the end portions are connected to each other so as to be movable toward and away from each other, and the start end portions of the guide members are bent in the outer peripheral direction of the funnel-shaped portion or the cylindrical portion, respectively. it you wherein forming the inserted flange portion larger diameter than said guide portion.
[0009]
By setting it as such a structure, since the terminal part of the several guide member which comprises the said auxiliary | assistant tool for packaging can each move to a diameter expansion direction and a diameter reduction direction, the auxiliary | assistant tool for packaging is set to a packaging bag. In such cases, the end of the guiding direction can be reduced in diameter so that it can be easily inserted into the packaging bag. When the packaged article is guided into the packaging bag, the guiding member is expanded by contact with the packaged article. Since the packaging bag is widened by moving in the radial direction, the article to be packaged can be smoothly introduced into the packaging bag. In addition, when the packaging aid is pulled out from the packaging bag after the packaged article has been guided into the packaging bag, the terminal portion of the guiding member is enlarged or reduced in diameter depending on the state of the packaging bag and the packaged article. Because it is possible, it can be easily detached from the packaging bag.
[0010]
Here, if a support shaft or a hinge for connecting the adjacent guide members to each other in a tiltable manner is provided as a connecting means for the plurality of guide members, the end portions in the guide direction of the guide members are separated from each other with a relatively small force. Since it can be moved, the detachability to the packaging bag and the introduction function of the package are further improved, and the packaged material passing through the packaging auxiliary tool can be moved into the packaging bag without damaging it. You will be able to guide.
[0011]
As described above, when the guide members are connected to each other by a support shaft in a tiltable manner, when the end portion in the guide direction of the guide member moves in the diameter increasing direction, the portion above the support shaft of the guide member is reduced in diameter accordingly. Since it moves to a direction, the opening part of the packaging aid may become narrow and the guidance function of a package may fall. Therefore, if the support shaft is disposed close to the starting end portion of the guide member in the guide direction, the range of diameter reduction (the portion above the support shaft of the guide member) is reduced as the terminal portion of the guide member expands. Therefore, it is possible to suppress a decrease in guidance function due to narrowing of the opening.
[0012]
In this case, if the starting end portion of the guide member excluding the portion where the support shaft is disposed is bent or notched toward the end portion, or bent into the outer peripheral direction, the end portion of the guide member Since the starting end portion that is reduced in diameter as the diameter is increased can be further reduced, the effect of suppressing a reduction in the guidance function is enhanced.
[0013]
If a planar guide member and a bowl-shaped guide member arranged with a concave surface facing the planar guide member are used as the guide member, a guide path having a bowl-shaped cross section is formed in the packaging aid. Therefore, it becomes suitable for use when packaging work is performed with the packaging bag with the opening up on the surface of the vertical support plate, and the packaged items are smoothly introduced into the suspended packaging bag. Will be able to.
[0014]
That is, the packaging bag suspended from the surface of the vertical support plate cannot be expanded in the direction of the vertical support plate, but the end portion of the packaging auxiliary tool is arranged so that the planar guide member faces the vertical support plate. Is inserted into the packaging bag, it is possible to spread the packaging bag by moving the terminal end of the hook-shaped guide member in the direction without the vertical support plate, so as in the suspended packaging bag And it becomes suitable when the terminal part of an induction | guidance | derivation member cannot carry out diameter expansion movement to the perimeter direction, and also in this case, a to-be-packaged item can be smoothly introduce | transduced in a packaging bag.
[0015]
Here, if the bottom of the hook-shaped member has a shape approaching the planar guide member in accordance with the guide direction of the article to be packaged, the terminal end side of the guide member can be thinned. It is possible to enhance the insertion property into the packaging bag and the detachability from the packaging bag after the package is introduced. In this case, as a shape for approaching the bottom of the bowl-shaped member to the planar guide member, a shape approaching linearly, a shape approaching curved, or the like can be adopted according to the property of the package. .
[0016]
Further, if at least one of the guide members has a tapered shape whose width is reduced in accordance with the guide direction of the package, it is possible to move the terminal end side of the guide member closer and closer to reduce the diameter. Therefore, the insertion property into the packaging bag and the detachability from the packaging bag after introduction of the package can be improved.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view showing the packaging auxiliary tool according to the first embodiment of the present invention as viewed obliquely from above, and FIG. 2 is a perspective view of the packaging aid shown in FIG. 1 as seen from diagonally below. 3 and 4 are explanatory views showing a packaging operation using the packaging auxiliary tool shown in FIG.
[0018]
As shown in FIGS. 1 and 2, the packaging auxiliary tool 1 of the present embodiment has a funnel shape with eight guide members 2 having a planar guide portion 2 a for guiding a package object in a certain direction. These guiding members 2 are formed by being connected by ring-shaped support shafts 3 so that the end portions 2b in the guiding direction can move toward and away from each other. Since the eight guide members 2 are tiltable about the support shaft 3, the terminal portions 2b of the guide members 2 are movable in the diameter increasing direction and the diameter reducing direction.
[0019]
When a packaging operation is performed using the packaging auxiliary tool 1, the opening 5a of the packaging bag 5 held in a suspended state on the vertical support plate 4 with the opening 5a facing upward as shown in FIG. Then, the terminal portion 2b of the guide member 2 of the packaging auxiliary tool 1 is inserted in a narrowed state. At this time, the end portions 2b of the respective guide members 2 are close to each other and are in the most contracted state, so that they can be easily inserted. Moreover, since the heel portion whose diameter is larger than that of the guiding portion 2a is formed by bending the starting end portion 2c of each guiding member 2 in the outer circumferential direction, the packaging auxiliary tool 1 falls into the packaging bag 5. I don't have to.
[0020]
Thereafter, as shown in FIG. 3 (b), when a plurality of eggplants N, which are the objects to be packaged, are bundled in a substantially vertical state and inserted into the packaging auxiliary tool 1, a part of the bundled eggplant N is guided. The guide member 2 is abutted against the guide portion 2a of the member 2 and pressed in the outer peripheral direction. As shown in FIG. 3C, the terminal portion 2b of each guide member 2 is expanded in diameter, so that the eggplant N is naturally dropped. The eggplant N can be smoothly introduced into the packaging bag 5 by simply pressing it down. In this case, since the support shaft 3 is disposed close to the starting end portion 2c of the guiding member 2, even if the terminal end portion 2b of the guiding member 2 moves in the diameter increasing direction, the starting end portion 2c is greatly reduced in diameter. Does not inhibit the induction function.
[0021]
When eggplant N is introduced into the packaging bag 5 as shown in FIG. 4 (a), the packaging auxiliary tool 1 is removed from the packaging bag 5, and then only the packaging bag 5 containing eggplant N is pulled downward. When the packaging bag 5 is detached from the support plate 4, the lower portion of the opening 5a is bound with the adhesive tape 6 or the like, and the excess portion 5b near the opening 5a is cut and removed, the packaging operation is completed.
[0022]
When the auxiliary packaging tool 1 is taken out from the packaging bag 5 after the introduction of the eggplant N, the end portion 2b of the guide member 2 can be freely expanded and contracted according to the condition of the packaging bag 5 and the eggplant N, respectively. Therefore, it is easy to leave the packaging bag 5. If the packaging auxiliary tool 1 detached from the packaging bag 5 is inserted into the bag through the opening a of the empty packaging bag 5 suspended from the vertical support plate 4 as shown in FIG. The following packaging operation can be performed according to the procedure described above.
[0023]
Since the packaging auxiliary tool 1 includes the eight guide members 2, it is excellent in that the packaging bag 5 can be expanded almost in the entire circumferential direction when the article to be packaged is introduced. The use of the packaging aid 1 is not particularly limited, but is suitable when a relatively hard and round article or an article having a good slip property and a long article is introduced into the packaging bag 5. Further, in a state where the packaging auxiliary tool 1 is set in the packaging bag 5, the packaging operation is performed by inserting the hand into the packaging bag 5 through the packaging auxiliary tool 1, or the hand is inserted into the packaging bag 5. Since the items to be packaged can be arranged, the convenience is excellent.
[0024]
Next, the packaging auxiliary tool 11 which is 2nd embodiment of this invention is demonstrated with reference to FIG. 5, FIG. As illustrated in FIG. 5, the packaging auxiliary tool 11 includes two guide members 12 having concave curved guide portions 12 a arranged in a funnel shape with the concave curved surfaces facing each other. They are formed by connecting them with a flexible and bendable hinge 13.
[0025]
Therefore, as shown in FIG. 6, the two guide members 12 of the packaging auxiliary tool 11 can be tilted in the direction in which the end portions 12 b in the guide direction move toward and away from each other around the hinge 13. As a result, the end portion 12b moves so as to expand and contract.
[0026]
The packaging auxiliary tool 11 is used in the same manner as the packaging auxiliary tool 1 described above, and the same functions and effects can be obtained. However, since there are two guide members 12 constituting the packaging auxiliary tool 11, it is manufactured. In addition, since the vicinity of the lower end portion 12b is minimized by merely bringing the end portions 12b of the two guide members 12 into close contact with each other, the insertion into the packaging bag 5 is easy. The use of the packaging aid 11 is not particularly limited, but is suitable when a soft article such as a relatively hard and round article or a good and slippery article is introduced into the packaging bag 5. .
[0027]
Next, the packaging auxiliary tool 21 which is 3rd embodiment of this invention is demonstrated with reference to FIG. 7, FIG. As shown in FIG. 7, the packaging auxiliary tool 21 of the present embodiment includes a flat plate-shaped guide member 22 having a planar guide portion 22 a, and a bowl-like shape arranged with the concave guide portion 23 a facing the guide member 22. The guide member 23 is connected to the support shaft 24 so as to be tiltable. Therefore, the end portion 23 b of the bowl-shaped guide member 23 can move toward and away from the guide member 22.
[0028]
In the packaging aid 21, as shown in FIG. 7C, a guide path 24 having a bowl-shaped cross section is formed in the packaging aid 21, so that the opening 5a is formed as shown in FIG. It is suitable for use when packaging work is performed in a state in which the packaging bag 5 placed above is suspended from the surface of the vertical support plate 4.
[0029]
As shown in FIG. 8, the packaging bag 5 suspended on the surface of the vertical support plate 4 cannot be expanded in the direction of the vertical support plate 4, but the flat guide member 22 faces the vertical support plate 4. If the end portion of the packaging auxiliary tool 21 is inserted into the packaging bag 5, the packaging bag 5 can be expanded by moving the end portion 23 b of the hook-shaped guide member 23 in the direction without the vertical support plate 4. Become. Therefore, it is suitable for a packaging operation when the terminal portion of the guide member 22 cannot move toward the vertical support plate 4 as in the suspended packaging bag 5. Spinach H can be smoothly introduced into the packaging bag 5.
[0030]
In the packaging auxiliary tool 21, as shown in FIG. 7 (b), the widths of the guide member 22 and the bowl-shaped guide member 23 are tapered along the guide direction of the packaged portion, and FIG. As shown in a), the bottom 23c of the bowl-shaped guide member 23 has a shape that linearly approaches the guide member 22 in accordance with the guide direction of the article to be packaged, so that the vicinity of the end 23b is reduced in diameter. Can be smoothly inserted into the packaging bag 5.
[0031]
In addition, since the entire packaging auxiliary tool 21 has an insertion shape by extending the starting end portion of the guiding member 22 from the starting end portion of the bowl-shaped guiding member 23, Introduction can be performed very smoothly. In addition, since the packaging auxiliary tool 21 includes the guide member 22 and the bowl-shaped guide member 23 that are relatively longer than the packaging auxiliary tools 1 and 11, it is excellent in that it can be opened to the vicinity of the bottom of the packaging bag. Therefore, it is suitable for a packaging operation in which a relatively long article having a poor slip property or a relatively soft and round article is introduced into a packaging bag.
[0032]
Next, the packaging auxiliary tool 31 which is 4th embodiment of this invention is demonstrated with reference to FIG. As shown in FIG. 9, the packaging auxiliary tool 31 of the present embodiment includes a flat plate-like guide member 32 having a flat guide portion 32 a and four flat plate-like shapes each having a narrow flat guide portion 33 a. The guide members 33 are arranged so as to form a substantially pentagonal cylinder shape, and the vicinity of the start ends of the guide members 32 and 33 are connected to the support shaft 34 so as to be tiltable. A portion of the guide member 33 located above the support shaft 34 is bent outward.
[0033]
The packaging auxiliary tool 31 is used in the same manner as the packaging auxiliary tool 21 shown in FIG. 8 and can provide the same functions and effects. However, in the case of the packaging auxiliary tool 31, four plate-shaped guides are used. Since the member 33 is provided and the packaging bag can be opened in four directions, it is suitable for packaging an article having a shape such as leafy vegetables.
[0034]
Next, the packaging auxiliary tool 41 which is 5th embodiment of this invention is demonstrated with reference to FIG. 10, FIG. As shown in FIG. 10, the packaging auxiliary tool 41 has a cylindrical shape including a square hook-shaped guide member 42 having a planar guide portion 42a and a hook-shaped guide member 43 having a concave curved guide portion 43a. Thus, the end portion 42b of the guide member 42 and the end portion 43b of the bowl-shaped guide member 43 are movable toward and away from each other. The bottom part 43d of the bowl-shaped guide member 43 has a shape that is curvedly approached toward the guide member 42 in accordance with the guide direction of the package.
[0035]
In the packaging auxiliary tool 41, since the starting end portion 43c of the bowl-shaped guide member 43 is curved in the direction of the terminal end portion 43b, when the terminal ends 42b and 43b are moved in the separation direction, the bowl-shaped guide member 43 is moved. Since the starting end portion 43c does not approach the direction of the guiding member 42 as indicated by the phantom line S in FIG. 10B, the packaging operation is not hindered by the reduced diameter of the opening.
[0036]
As described above, the packaging auxiliary tool 41 can be inserted into the packaging bag 5 suspended in the vertical state as shown in FIG. 11 to perform the packaging work of spinach H and the like. Functions and effects similar to those of the packaging auxiliary tools 21 and 31 can be obtained.
[0037]
In the packaging auxiliary tool 42, the hook bottom portion 43d of the hook-shaped guide member 43 has a shape that is curvedly approached toward the guide member 42 toward the terminal end portion 43b, and therefore, as shown in FIG. In addition, after the spinach H is introduced into the packaging bag 5, when the packaging auxiliary tool 41 is taken out of the packaging bag 5, if the packaging auxiliary tool 41 is pulled upward, the vicinity of the central portion X of the heel bottom portion 43 d is filled with the spinach H. Since the leaf portion and the like are pressed inward, and the end portion 43b pushes the packaging bag 5 outward, it is very easy to take out.
