Abstract

<P>PROBLEM TO BE SOLVED: To stably load merchandise by controlling the behavior of merchandise dropping inside a merchandise passage during merchandise loading. <P>SOLUTION: This merchandise storage device of a vending machine has a merchandise passage with a serpentine structure for storing merchandise inserted from a merchandise slot. Column segments 13 each having an approximately arcuate cross section and facing each other across the merchandise passage 12 are arranged in a zigzag configuration to form the meandering merchandise passage 12. The device is installed so that the curved surface of each column segment 13 has its curvature axis titled relative to a horizontal plane. For an unstable container with weight imbalance along its height, each column segment moves in sliding contact with the container at two points, the bottom and the shell of the container, enabling the merchandise to be stably loaded while automatically adjusting its attitude. On the basis of the relationship between the behavior of the merchandise dropping inside the merchandise passage and the column segments during merchandise loading, the merchandise passage to be formed is changed in configuration by the arrangement of the column segments and the attitude-adjusting function of the segments is used effectively to prevent the merchandise from standing. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明はビン、缶、ペットボトル等の容器に詰められた商品を販売する自動販売機に搭載したサーペンタイン式の商品収納装置に関するものである。
【0002】
【従来の技術】
近年の飲料容器は形状、材質等が多種多様であり、自動販売機での販売においては、商品収納ラックに整列させて収納するために各々商品に合わせて、工夫をこらしている。そのため、収納商品に合わせて調整板等を移動させる必要が生じることになり、商品を補充するオペレーターには負担となっている。
【0003】
また、調整板等を移動しないまま商品を投入すると、商品が商品通路の途中で立ってしまい、商品詰まり等の不具合が頻繁に発生することがある。
【0004】
そこで、自動販売機のサーペンタイン式商品収納ラックでは、投入商品が途中で立つことを防ぐために、円弧板状のセグメントに工夫を施している。
【0005】
従来の自動販売機の商品収納装置に搭載したサーペンタイン式商品収納ラックとして、セグメントの円弧板面に斜め方向にビードを設けたものがある(例えば、特許文献1参照。)。
【0006】
以下、図面を参照しながら上記従来の自動販売機の商品収納装置を説明する。
【0007】
図3は従来の自動販売機の商品収納装置の斜視図、図4は従来の自動販売機の商品収納装置の断面図、図5は従来の自動販売機の商品収納装置のコラムセグメントの詳細図、図6は従来の自動販売機の商品収納装置の商品収納状態を示す断面図である。
【0008】
図3、図4に示すように、従来の自動販売機の商品収納装置は商品収納ラックの左右に垂直方向に立設した側板1aと、側板1bの間に架け渡して上下方向の蛇行状商品通路2を画成するように千鳥状に配列したコラムセグメント3と、商品通路の上端に連ねてその上部側に配した商品投入用のトップトレー4と、出口通路幅を規制する出口アジャスタ5と、商品通路の下部出口端側に配した商品搬出用のベンド機構6とから構成されている。
【0009】
また図5、図6に示すようにコラムセグメント3に対し、その板面には商品通路の向き(上下方向)に対して斜め方向に延在して並ぶ複数条のビード3aが傾斜角度θをもって形成されている。
【0010】
このように傾斜したビード3aを形成しておくことにより、商品ローディング時に姿勢の乱れから縦向き姿勢になって商品通路2に進入してきた商品7aは、コラムセグメント3の板面を滑動して下方に落下する過程で、その板面に斜めに延在するビード3aに沿ってガイドされ、縦向きから横向きに戻すように姿勢が矯正される。これにより商品通路2の途中で商品7bのようにブリッジするなどのトラブル発生から回避される。
【0011】
【特許文献1】
特開2003−99850号公報
【0012】
【発明が解決しようとする課題】
しかしながら上記従来の構成では、商品収納ラックへのローディング時の”缶立ち”に対して、矯正力が作用するのは容器とコラムセグメント3が接触している状態に依存するため、大小各容量の商品のうち中身容量の少ない短小サイズにおいて効果が薄く、且つ外形形状が概ね円筒状の缶容器等に限定されることになる。特に、キャップつき容器等のように商品の全長に対して重量バランスに偏りがあり、容器の一端側がコラムセグメント3に直接接触することの可能性が低い容器にとっては、姿勢の矯正作用が働かず効果が期待できないことになる。
【0013】
さらに、縦向きにて商品通路に侵入した容器は、姿勢の矯正に至るまでにある一定の落下距離が必要となるため、充填済みの商品が多く残っている状態では、姿勢が修正を終えるまでに下方に積み上げ収納されている商品7bに到着してしまい、商品が立った状態のまま商品上に着地して結果的に商品詰まりを引き起こしてしまう。
【0014】
また、本来正常状態で容器が水平姿勢を維持している状態にあっては、コラムセグメント3のビード3aは逆に姿勢を縦向きに変えようとする矯正力として作用するために、姿勢が不安定になり易く、ひとたび縦向き姿勢となった商品7aは、縦向き姿勢を保ったまま商品通路2の途中で詰まってしまうブリッジ状態が発生することや、あるいは既に下方に積み上げ収納されている商品の上に着地して商品詰まりを引き起こす。しかも、このような商品詰まりが発生した状態を放置しておくと、ベンド機構6による商品販売動作が正常に行われなくなるので、キャビネットからラック10を引き出して通路途中に詰まっている商品を取り除くなど、外部から商品の収納姿勢を矯正するなどの面倒な作業が強いられる。
【0015】
そこで、本発明は従来の課題を解決するもので、商品ローディング時に商品通路内を落下する商品の挙動とコラムセグメントとの関係を基に、コラムセグメントの構成により形成する商品通路形態を変更し、その姿勢調整機能を有効に生かして商品の缶立ちを回避できるように改良した自動販売機のサーペンタイン式商品収納ラックを提供することを目的とする。
【0016】
【課題を解決するための手段】
請求項1に記載の発明は、商品投入口から投入されて商品を収納するサ−ペンタイン構造の商品通路を備えた自動販売機の商品収納装置において、商品通路を挟んで向かい合わせに対峙する断面略円弧状のコラムセグメントを千鳥状に配列して蛇行状の商品通路を形成し、コラムセグメントの湾曲面の曲率軸が水平面に対して傾斜するように設置したものであり、容器高さ方向に対して重量バランスに偏りのある不安定な容器に対して、容器底部および容器胴部の2点で接触摺動することで、姿勢を自動調整しながら安定した状態で商品を搬送できるという作用を有する。
【0017】
また、請求項2に記載の発明は、請求項1に記載の発明に、さらに商品通路は複数の側板と前記側板間に軸支され、断面が円弧状のコラムセグメントを千鳥状に配列した蛇行形状とし、水平に対し傾斜している前記コラムセグメントの支軸を備えたものであり、容器高さ方向に対して重量バランスに偏りのある不安定な容器に対して、容器底部および容器胴部の2点で接触摺動することで、姿勢を自動調整しながら安定した状態で商品を搬送できるとともに、コラムセグメントが可動することにより、落下する商品に対して接触摺動する機会が増えることでより積極的に姿勢を自動調整しながら安定した状態で商品を搬送できるという作用を有する。
【0018】
また、請求項3に記載の発明は、請求項1または請求項2に記載の発明に、さらに商品投入口から商品通路まで商品を転動させる商品案内板を設け、前記コラムセグメントの支軸と同じ方向に傾斜している前記商品案内板を備えたものであり、商品の投入に際して、容器の底部を基点に摺動しながら安定して商品投入口から商品通路まで商品を転動もしくは滑動させる作用を有する。
【0019】
【発明の実施の形態】
以下、本発明による自動販売機の商品収納装置の実施例について図面を参照しながら説明する。尚、従来と同一構成については同一符号を付し、その詳細な説明を省略する。
【0020】
(実施の形態1)
図1は、本発明の実施の形態1による自動販売機の商品収納装置の斜視図である。図2は、同実施の形態の商品収納装置の正面からの断面図である。
【0021】
図1,図2において、商品収納ラック10は、左右に垂直方向に立設した側板11は商品収納ラックの正面から向かって右側の側板11aと左側の側板11bで構成され、側板11bから側板11bの方向に傾斜して架け渡して上下方向の蛇行状商品通路12を画成するように千鳥状に配列したコラムセグメント13と、商品通路12の上端に連ねてその上部側に配した商品投入用のトップトレー14と、出口通路幅を規制する出口アジャスタ15と、商品通路12の下部出口端側に配した商品搬出用のベンド機構16とから構成されている。
【0022】
コラムセグメント13については、厚さ0.5mm程度の薄鋼板をプレス加工して略円弧状に湾曲成形したもので、コラムセグメント13の湾曲面の曲率軸は水平面に対して傾斜角度αをもって設置されており(側板11への取付け軸の角度が傾斜角度αとなる)の、商品通路12に沿って上下方向に半ピッチづつずらして向かい合うように千鳥状に配列してそのセグメント間に蛇行状の商品通路12を画成している。コラムセグメント13は、コラム内に積み上げ収納した商品17の重量荷重,および商品通路12を転動落下する商品17の衝撃荷重で変形しないように剛性を付与している。
【0023】
また、出口アジャスタ15とベンド機構16については、コラムセグメント13と同様、水平面に対して傾斜角度αをもって設置されている。
【0024】
以上のように構成された自動販売機の商品収納装置について、以下その動作を説明する。
【0025】
まず、商品収納ラック10の商品販売動作は周知であり、商品17は商品収納ラック10のベンド機構16から販売指令に基づき搬出され、商品取出口に送出される。商品補充時(ローディング)には商品を横向きの倒置姿勢にして前方より商品収納ラック10のトップトレー14へと投入する。商品17はトップトレー14の上を転動してその後端から蛇行状の商品通路12に進入し、前後に対峙して千鳥状に並ぶコラムセグメント13の円弧面に沿ってガイドされながら下方に落下して図示のように上下一列に積み上げ収納される。
【0026】
ここで、通常の円筒形容器は元より、特にキャップ付容器等のように商品が横向きの倒置姿勢状態において、重心が商品長の中心になく、所謂重量的なバランスに偏りのある容器に関する商品通路12内の商品落下挙動において、蛇行するコラムセグメント13が水平面に対して傾斜しているため、常にコラムセグメント13からの接触反力として下方傾斜した側板11a側に向かう方向へと分力を受ける。そのため、落下挙動中において滑落案内されて容器の一端側を常に側板11aに沿わせながら落下することとなる。
【0027】
この際、容器の一端は側板11aに摺動しながら移動するため、容器の傾斜下端側が下向きに先落ち回転して商品が立とうとする挙動を抑制する方向に摩擦力による回転モーメントが作用する。また、落下姿勢が乱れて容器の傾斜下端側の先落ち回旋が進み、商品落下の姿勢角度がコラムセグメント13の傾斜角度αを上回った場合には、容器の傾斜下端側がコラムセグメント13と先に衝突干渉し始めることで姿勢を元に戻す方向への旋回モーメントが生じて自動的に姿勢修正を行うこととなる。
【0028】
逆に、容器の側板11との反接触端側が先落ちして下向きに回転しようとした場合には、反接触端側がコラムセグメント13と先に衝突干渉し始めることになるため、結果的に落下姿勢が乱れた場合にも姿勢角度を常に維持する方向へと自動的に姿勢修正を行うことになる。
【0029】
次に、落下した商品は、商品通路12の出口端側に配した商品搬出用のベンド機構16に到達して順次傾斜状態のまま積み上がっていく。
【0030】
商品収納ラック10の商品通路12内における幅規制を行う可動側板が不要となり、安価で生産性の良い製品の提供が可能となるほか、各種販売商品の商品長に応じたトップトレー14での幅設定作業が不要となり、商品充填等のオペレーション効率の向上が図れるとともに、誤設定による商品詰まり等の不具合発生を回避することができる。
【0031】
また、商品通路12が傾斜して構成されているため、同一高さの商品を倒置収納した場合、側板11間同士の幅が狭く設定できて、機器本体の小型化または機器本体同一の場合には断熱壁厚寸法増加等により機器の省エネに寄与できる。
【0032】
以上のように本実施の形態の自動販売機の商品収納装置は、商品投入口から投入されて商品を収納するサ−ペンタイン構造の商品通路を備えた自動販売機の商品収納装置において、商品通路を挟んで向かい合わせに対峙する断面略円弧状のコラムセグメントを千鳥状に配列して蛇行状の商品通路を形成し、コラムセグメントの湾曲面の曲率軸が水平面に対して傾斜するように形成することで、キャップ付の容器等のように容器高さ方向に対して重量バランスに偏りのあるバランスの不安定な容器に対しても、商品通路内への充填落下時において、容器底の一端を摺動しつつコラムセグメントが容器胴部と接触摺動することで、ある一定の姿勢角度の範囲内に姿勢を維持するべく自動調整しながら安定した状態で商品を落下搬送することができる。
【0033】
また、商品投入口から投入されて商品を収納するサ−ペンタイン構造の商品通路を備えた自動販売機の商品収納装置において、前記商品通路は複数の側板と前記側板間に軸支され、断面が円弧状のコラムセグメントを千鳥状に配列した蛇行形状とし、前記コラムセグメントの支軸を水平に対し傾斜して形成したことで、キャップ付の容器等のように容器高さ方向に対して重量バランスに偏りのあるバランスの不安定な容器に対しても、商品通路内への充填落下時において、容器底の一端を摺動しつつコラムセグメントが容器胴部と接触摺動することで、ある一定の姿勢角度の範囲内に姿勢を維持するべく自動調整しながら安定した状態で商品を落下搬送することができる。
【0034】
また、商品投入口から商品通路まで商品を転動させる商品案内板を設け、前記コラムセグメントの支軸と同じ方向に傾斜している前記商品案内板を形成したことにより、商品の投入に際して、容器の底部を基点に摺動しながら安定して商品投入口から商品通路まで商品を転動もしくは滑動により搬送させることができる。
【0035】
なお、図2に示すとおり本実施の形態では、商品搬出用のベンド機構16は傾斜させて取付けられているが、商品通路12の下方に収納された商品17(ベンド機構16に近い商品17)を姿勢変更板(図示しない)にて2本程度水平方向に収納させることで、ベンド機構16を従来と同様に水平に配置させることができる。この構造であれば、商品17が商品通路12を落下するときは、商品17は側板11aに摺動しながら、安定した姿勢を保って、商品通路12に積み上がることができる。また、商品17の搬出時は水平に保持されていることから、従来どおりの安定した搬出が可能である。
【0036】
【発明の効果】
以上説明したように請求項1記載の発明は、サーペンタイン構造の商品収納装置において、商品通路を挟んで向かい合わせに対峙する断面略円弧状のコラムセグメントを千鳥状に配列して蛇行状の商品通路を形成し、コラムセグメントの湾曲面の曲率軸が水平面に対して傾斜するように設置することで、商品ローディング時に商品通路内を落下する商品の挙動とコラムセグメントとの関係を基に、コラムセグメントの構成により形成する商品通路形態を変更し、その姿勢調整機能を有効に生かして商品の缶立ちを回避することができる。
【0037】
また、請求項2に記載の発明は、サーペンタイン構造の商品収納装置において、商品通路は複数の側板と前記側板間に軸支され、断面が円弧状のコラムセグメントを千鳥状に配列した蛇行形状とし、前記コラムセグメントの支軸が水平に対し傾斜していることで、コラムセグメントが可動することにより、落下する商品に対して接触摺動する機会が増えることでより積極的に姿勢を自動調整しながら安定した状態で商品を搬送することができる。
【0038】
また、請求項3に記載の発明は、さらに商品投入口から商品通路まで商品を転動させる商品案内板を設け、前記コラムセグメントの支軸と同じ方向に傾斜している前記商品案内板を備えたので、商品の投入に際して、容器の底部を基点に摺動しながら安定して商品投入口から商品通路まで商品を転動もしくは滑動させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a serpentine-type product storage device mounted on a vending machine that sells products packed in containers such as bottles, cans, and PET bottles.
[0002]
[Prior art]
BACKGROUND ART In recent years, beverage containers have various shapes, materials, and the like, and in vending machines, in order to arrange and store the products in a product storage rack, each device is devised in accordance with each product. For this reason, it is necessary to move the adjusting plate or the like in accordance with the stored product, which is a burden on the operator who replenishes the product.
[0003]
In addition, when a product is put in without moving the adjustment plate or the like, the product stands in the middle of the product path, and a problem such as product clogging may frequently occur.
[0004]
Therefore, in a serpentine-type product storage rack of a vending machine, an arc plate-shaped segment is devised in order to prevent the input product from standing on the way.
[0005]
2. Description of the Related Art As a serpentine-type product storage rack mounted on a product storage device of a conventional vending machine, there is one in which a bead is provided diagonally on an arc plate surface of a segment (for example, see Patent Document 1).
[0006]
Hereinafter, a product storage device of the above-mentioned conventional vending machine will be described with reference to the drawings.
[0007]
3 is a perspective view of a conventional vending machine product storage device, FIG. 4 is a cross-sectional view of a conventional vending machine product storage device, and FIG. 5 is a detailed view of a column segment of the conventional vending machine product storage device. FIG. 6 is a cross-sectional view showing a product storage state of a conventional product storage device of a vending machine.
[0008]
As shown in FIGS. 3 and 4, a conventional vending machine product storage device includes a vertical vertical meandering product that is bridged between a side plate 1a and a side plate 1b that are vertically installed on the left and right sides of a product storage rack. A column segment 3 arranged in a staggered manner so as to define a passage 2, a top tray 4 for commodities which is connected to an upper end of the commodity passage and arranged on an upper side thereof, and an exit adjuster 5 for regulating an exit passage width. And a bend mechanism 6 for unloading goods disposed on the lower exit end side of the goods passage.
[0009]
As shown in FIGS. 5 and 6, a plurality of beads 3a are arranged on the plate surface of the column segment 3 so as to extend obliquely with respect to the direction of the product passage (vertical direction) with an inclination angle θ. Is formed.
[0010]
By forming the inclined bead 3a in this manner, the product 7a that has entered the product path 2 from the disordered posture during loading of the product and has entered the product path 2 by sliding down the plate surface of the column segment 3, In the process of falling, the guide is guided along the bead 3a extending obliquely to the plate surface, and the posture is corrected so as to return from the vertical to the horizontal. This avoids the occurrence of troubles such as bridging like the product 7b in the middle of the product path 2.
[0011]
[Patent Document 1]
JP 2003-99850 A
[Problems to be solved by the invention]
However, in the above-mentioned conventional configuration, the corrective force acts on the "can standing" at the time of loading on the product storage rack, since it depends on the state where the container and the column segment 3 are in contact with each other. In a product, the effect is thin in a small size having a small content capacity, and the external shape is limited to a substantially cylindrical can. In particular, for a container such as a container with a cap, which has a bias in the weight balance with respect to the entire length of the product and in which it is unlikely that one end of the container is in direct contact with the column segment 3, the posture correcting action does not work. The effect cannot be expected.
[0013]
In addition, a container that has entered the product passage in a vertical orientation requires a certain fall distance before the posture is corrected, so if there are many filled products remaining, the posture will be corrected Arrives at the product 7b which is stacked and stored below, and the product lands on the product while standing, resulting in product clogging.
[0014]
Also, in a state where the container maintains the horizontal posture in the normal state, the bead 3a of the column segment 3 acts as a correcting force for changing the posture to the vertical direction, so that the posture is not correct. The product 7a, which is likely to be stable and once in the vertical position, may cause a bridge state in which the product 7a is stuck in the product path 2 while maintaining the vertical position, or a product already stacked and stored below. Land on the top and cause the product to jam. In addition, if the state in which such product clogging occurs is left as it is, the product selling operation by the bend mechanism 6 will not be performed normally, so that the rack 10 is pulled out from the cabinet and the product clogged in the passage is removed. In addition, troublesome work such as correcting the storage posture of the product from the outside is forced.
[0015]
Therefore, the present invention is to solve the conventional problem, based on the relationship between the behavior of the product falling in the product passage during the loading of the product and the column segment, by changing the product passage form formed by the configuration of the column segment, An object of the present invention is to provide a serpentine-type product storage rack of a vending machine improved so that the product can be prevented from standing up by effectively utilizing the posture adjusting function.
[0016]
[Means for Solving the Problems]
A cross section of a vending machine provided with a serpentine-structured merchandise passage for accommodating a merchandise inserted from a merchandise insertion port, the cross-section facing each other across the merchandise passage. Approximately arc-shaped column segments are arranged in a zigzag pattern to form a meandering product passage, and the curvature axis of the curved surface of the column segment is installed so as to be inclined with respect to the horizontal plane. On the other hand, by contacting and sliding at two points, the container bottom and the container body, on an unstable container with a biased weight balance, the product can be transported in a stable state while automatically adjusting the posture. Have.
[0017]
According to a second aspect of the present invention, in addition to the first aspect, the commodity passage is pivotally supported between the plurality of side plates and the side plates, and the meandering is formed by arranging column segments having an arc-shaped cross section in a staggered manner. It has a shape, and has a support shaft of the column segment that is inclined with respect to the horizontal. For an unstable container having a bias in weight balance in the container height direction, a container bottom portion and a container body portion are provided. By sliding the contact at two points, the product can be transported in a stable state while automatically adjusting the posture, and by moving the column segment, the chance of contact sliding against the falling product increases. This has the effect that the product can be transported in a stable state while the posture is automatically adjusted more positively.
[0018]
According to a third aspect of the present invention, in addition to the first or second aspect of the present invention, a product guide plate for rolling a product from a product input port to a product path is provided, and a support shaft of the column segment is provided. It is provided with the product guide plate inclined in the same direction, and when loading the product, the product is rolled or slid from the product insertion port to the product passage stably while sliding around the bottom of the container as a base point. Has an action.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a product storage device of a vending machine according to the present invention will be described with reference to the drawings. The same components as those of the related art are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0020]
(Embodiment 1)
FIG. 1 is a perspective view of a product storage device of a vending machine according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view from the front of the product storage device of the embodiment.
[0021]
1 and 2, a product storage rack 10 is configured such that a side plate 11 erected in a vertical direction in the left and right direction includes a right side plate 11a and a left side plate 11b as viewed from the front of the product storage rack, and the side plates 11b to 11b. Column segments 13 arranged in a staggered manner so as to define a vertical meandering product passage 12 by being laid in a slanting direction, and a product input arranged on the upper side thereof connected to the upper end of the product passage 12. , An outlet adjuster 15 for regulating the width of the outlet passage, and a bend mechanism 16 for carrying out the goods disposed on the lower outlet end side of the goods passage 12.
[0022]
The column segment 13 is formed by pressing a thin steel plate having a thickness of about 0.5 mm into a substantially arc-shaped curve, and the curvature axis of the curved surface of the column segment 13 is set at an inclination angle α with respect to a horizontal plane. (In which the angle of the axis of attachment to the side plate 11 is the inclination angle α), are arranged in a zigzag manner so as to face each other by being shifted by a half pitch in the vertical direction along the product path 12 and meandering between the segments. A product passage 12 is defined. The column segment 13 is provided with rigidity so as not to be deformed by the weight load of the products 17 stacked and stored in the column and the impact load of the products 17 rolling and falling down the product path 12.
[0023]
The outlet adjuster 15 and the bend mechanism 16 are installed at an inclination angle α with respect to a horizontal plane, similarly to the column segment 13.
[0024]
The operation of the commodity storage device of the vending machine configured as described above will be described below.
[0025]
First, the product sales operation of the product storage rack 10 is well known, and the product 17 is carried out from the bend mechanism 16 of the product storage rack 10 based on a sales command, and sent out to the product outlet. At the time of product replenishment (loading), the product is put into the top tray 14 of the product storage rack 10 from the front with the product placed in a horizontal inverted posture. The product 17 rolls on the top tray 14, enters the meandering product path 12 from the rear end, and falls downward while being guided along the arc surface of the column segments 13 that are arranged in a zigzag manner facing front and rear. Then, as shown, they are stacked and stored in a line up and down.
[0026]
Here, in addition to the ordinary cylindrical container, particularly in the case of a container with a cap or the like, when the product is in a horizontally inverted position, the center of gravity is not at the center of the product length, and the product relates to a container having a so-called weight-balanced bias. In the product falling behavior in the passage 12, since the meandering column segment 13 is inclined with respect to the horizontal plane, a component force is always applied as a contact reaction force from the column segment 13 in a direction toward the side plate 11 a inclined downward. . Therefore, the container is guided to slide down during the falling behavior, and falls while the one end side of the container always follows the side plate 11a.
[0027]
At this time, since one end of the container moves while sliding on the side plate 11a, a rotational moment due to a frictional force acts in a direction in which the inclined lower end of the container falls down and rotates to suppress the behavior of the product to stand up. Further, when the falling posture is disturbed and the falling edge of the container at the lower end side of the container advances, and the posture angle of the product falling exceeds the inclination angle α of the column segment 13, the inclined lower end side of the container comes first with the column segment 13. When the collision interference starts, a turning moment in the direction of returning the posture to the original position is generated, and the posture is automatically corrected.
[0028]
Conversely, if the anti-contact end side of the container with the side plate 11 falls down and tries to rotate downward, the anti-contact end side starts to collide with the column segment 13 first and consequently falls. Even if the posture is disturbed, the posture is automatically corrected in a direction that always maintains the posture angle.
[0029]
Next, the dropped commodities reach the commodity carrying-out bend mechanism 16 arranged on the exit end side of the commodity passage 12 and are sequentially stacked while being inclined.
[0030]
A movable side plate for controlling the width in the product passage 12 of the product storage rack 10 is not required, so that products can be provided at low cost and with high productivity, and the width of the top tray 14 according to the product length of various products for sale can be provided. The setting operation is not required, and the operation efficiency such as the filling of the product can be improved, and the occurrence of the trouble such as the product clogging due to the incorrect setting can be avoided.
[0031]
In addition, since the product passage 12 is configured to be inclined, when products of the same height are inverted and stored, the width between the side plates 11 can be set to be narrow, and when the size of the device body is reduced or the device body is the same. Can contribute to energy saving of equipment by increasing the thickness of the heat insulation wall.
[0032]
As described above, the merchandise storage device of the vending machine according to the present embodiment is the same as the merchandise storage device of the vending machine provided with a merchandise passage having a serpentine structure for storing merchandise inserted from the merchandise slot. The column segments having a substantially arc-shaped cross section facing each other are arranged in a staggered manner to form a meandering product passage, and the curvature axis of the curved surface of the column segment is formed to be inclined with respect to the horizontal plane. By this means, even for containers with an unstable balance, such as containers with caps, which have an imbalanced weight balance with respect to the container height direction, one end of the container bottom is used when filling and falling into the product passage. As the column segment slides into contact with the container body while sliding, the product can be dropped and conveyed in a stable state while automatically adjusting to maintain the posture within a certain posture angle range. .
[0033]
Further, in a product storage device of a vending machine having a product path of a serpentine structure for storing a product inserted from a product input port, the product path is pivotally supported between a plurality of side plates and the side plates, and has a cross section. The arc-shaped column segments are arranged in a zigzag shape in a zigzag shape, and the support shafts of the column segments are formed to be inclined with respect to the horizontal, so that the weight balance is achieved in the container height direction, such as a container with a cap. Even when the container is unbalanced and uneven, the column segment slides along one end of the container bottom and slides in contact with the body of the container when the product falls into the product passage. The product can be dropped and conveyed in a stable state while being automatically adjusted to maintain the posture within the range of the posture angle.
[0034]
Further, by providing a product guide plate for rolling the product from the product input port to the product passage and forming the product guide plate inclined in the same direction as the support shaft of the column segment, a container is provided when the product is loaded. The product can be stably conveyed from the product input port to the product path by rolling or sliding while sliding from the bottom of the product.
[0035]
As shown in FIG. 2, in the present embodiment, the bend mechanism 16 for carrying out the product is attached at an angle, but the product 17 stored below the product path 12 (the product 17 close to the bend mechanism 16). Are stored in a horizontal direction by a posture changing plate (not shown), so that the bend mechanism 16 can be horizontally arranged as in the related art. With this structure, when the product 17 falls down the product path 12, the product 17 can be stacked on the product path 12 while maintaining a stable posture while sliding on the side plate 11a. In addition, since the product 17 is held horizontally when the product 17 is carried out, it is possible to carry out the product stably as before.
[0036]
【The invention's effect】
As described above, according to the first aspect of the present invention, a serpentine-structured product storage device includes a serpentine-structured product storage device in which column segments having a substantially arc-shaped cross section that face each other across a product path are arranged in a staggered manner. Is formed so that the curvature axis of the curved surface of the column segment is inclined with respect to the horizontal plane. Based on the relationship between the behavior of the product falling in the product passage during product loading and the column segment, the column segment By changing the form of the product passage formed by the configuration described above, the product can be prevented from standing up by effectively utilizing the posture adjustment function.
[0037]
According to a second aspect of the present invention, in the merchandise storage device having a serpentine structure, the merchandise passage is pivotally supported between the plurality of side plates and the side plates, and has a meandering shape in which arc-shaped column segments are arranged in a staggered manner. Since the support shaft of the column segment is inclined with respect to the horizontal, the column segment is movable, so that the chance of contact and sliding against a falling product is increased. The product can be transported in a stable state.
[0038]
Further, the invention according to claim 3 further includes a product guide plate for rolling the product from the product input port to the product passage, and the product guide plate inclined in the same direction as the support shaft of the column segment. Therefore, when inserting the product, the product can be stably rolled or slid from the product insertion port to the product passage while sliding around the bottom of the container.
