Description

【0001】
【発明の属する技術分野】
この発明は、飲料入りのペットボトルや缶等の筒状商品を順次1個ずつ排出する自動販売機の商品排出装置に関する。
【0002】
【従来の技術】
飲料入りのペットボトルや缶等の筒状商品を販売する自動販売機においては、そのキャビネット内に商品収納装置として例えばサーペンタイン形のコラムが前後左右に配設され、こられコラム内に所定の筒状商品が積層して収納されている。
【0003】
そして各コラムの下部に商品排出装置が設けられ、これら商品排出装置により各コラム内の筒状商品がその最下層のものから順次1個ずつ排出されるようになっている。
【0004】
商品排出装置は、コラムから導入される筒状商品を通過させる排出通路と、この排出通路内に導入された筒状商品を係止し、所定の信号に応じてその係止を解除して筒状商品を下方に落下させて排出する商品排出機構とを備えている。そして従来、筒状商品を通過させる排出通路の幅は、その筒状商品の外径に適合する幅に規定されている。
【0005】
ところで自動販売機で販売する商品は、季節や売上げ等に応じて変更されるのが通例であり、その変更により筒状商品の外径も種々異なってくる。したがって、商品排出装置もその変更となった筒状商品の外径に適合するように調整する必要がある。
【0006】
一般に商品の排出通路は、固定壁ユニットとこれに対向する可動壁ユニットとで構成され、固定壁ユニットに商品の排出機構が備えられている。そして商品が変更となったときに、前記可動壁ユニットを移動してその可動壁ユニットと固定壁ユニットとの対向間の距離、つまり排出通路の幅を変更後の商品の外径に適合するように調整している。
【0007】
しかしながら、このような調整の作業はコラムの下方の狭い空間内に作業員が手を差し入れて手探りの状態で行なわなければならず、このため作業が面倒で煩わしく、また可動壁ユニットの移動位置の目視による確認ができず、往々にして誤った設定がなされてしまうことがある。
【0008】
また、1つのコラム内に外径の大きい筒状商品を収納したときには、その外径の大きい筒状商品により固定壁ユニットと可動壁ユニットの間の商品排出通路の幅がその外径に応じた大きな幅に設定されてその状態が維持されるから、コラム内に外径の大きな筒状商品を投入して収納する際に、その外径の大きな筒状商品に紛れてそれより外径の小さい筒状商品を誤って混入してしまったような場合に、その外径の小さな筒状商品が幅の大きな排出通路を素通りして誤って排出されてしまう恐れがある。
【0009】
そこで、本出願人は商品を係止する突没可能な一対の係止体を備えるガイドプレートを、その係止体が互いに向き合うように対向配置させ、その各ガイドプレートの係止体を互いに同期するように突没させて筒状商品を順次1個ずつ排出させる商品排出装置を提案し、既に特願2000−275374号として特許出願してある。
【0010】
この商品排出装置においては、作業員による調整作業を要することなく、径の異なる複数種の筒状商品を係止し、必要に応じて排出させることができる。
【0011】
この商品排出装置の概略的な構成を図3に示してあり、この商品排出装置は互いに対向してその対向間を筒状商品aの排出通路2となす一対のガイドプレート1a,1bを有し、これらガイドプレート1a,1bにはそれぞれ上下に位置し、かつ排出通路2に向かって交互に突没する第1および第2の一対ずつの係止体3a,3b,4a,4bが設けられている。
【0012】
これら係止体3a,3b,4a,4bはフラッパ状をなし、それぞれその一端側の基部がガイドプレート1a,1bに架設された支軸5を介して支持され、これら支軸5を中心に回動して排出通路2に対して突没するようになっている。そしてコラム(図示せず)から排出通路2内に筒状商品aが導入され、その最下層の筒状商品aが第1の一対の係止体3a,3bで支持されるようになっている。
【0013】
係止体3aを支持した支軸5と係止体3bを支持した支軸5は、同じレベルの位置にあり、その支軸5から係止体3a,3bの先端部までの長さ寸法はほぼ同じとなっている。
【0014】
また、係止体4aを支持した支軸5と係止体4bを支持した支軸5は、同じレベルの位置にあり、その支軸5から係止体3a,3bの先端部までの長さの寸法はほぼ同じとなっている。
【0015】
一方のガイドプレート1aの背面部には、ソレノイド等の駆動源10が設けられ、この駆動源10により一方のガイドプレート1aにおける係止体3a,4aが直接駆動されて回動するとともに、これら係止体3a,4aの動作がカムやギアを用いる連動機構(図示せず)を介して他方のガイドプレート1bにおける係止体3b,4bに伝達され、これにより一方のガイドプレート1aにおける係止体3a,4aと他方のガイドプレート1bにおける係止体3b,4bとが互いに対称的にほぼ同期して突没するようになっている。
【0016】
そして図3(A)に示す商品の販売待機状態から駆動源10に所定の信号が投入されると、駆動源10により駆動されて図3(B)に示すように第1の一対の係止体3a,3bがそれぞれ外側に回動してガイドプレート1a,1bの背面側に没入するとともに、第2の一対の係止体4a,4bが内側に回動してガイドプレート1a,1bの表面側に突出する。つまり第1の一対の係止体3a,3bが互いに開き、第2の一対の係止体4a,4bが互いに閉じ合う。
【0017】
そして第1の係止体3a,3bの没入動作に応じて排出通路2内の最下層の筒状商品aが自重でその下方に落下して排出されるとともに、その最下層の上の次層の筒状商品aが前記第2の係止体4a,4bによりその下側から支持される。
【0018】
そして最下層の筒状商品aが排出された後に、第1の係止体3a,3bが内側に回動して閉じ状態に復帰するとともに、第2の係止体4a,4bが外側に回動して開き、この開動作で次層の筒状商品aが下方に落下して閉状態にある第1の一対の係止体3a,3bにより支持され、販売待機状態となる。なお、各係止体3a,3b,4a,4bの突没動作はほぼ瞬間的に行なわれる。
【0019】
このようにして、駆動源10に所定の信号が投入される都度、排出通路2内の筒状商品aがその下層側のものから順次1個ずつ排出され、これが販売口を通して自動販売機の利用者に販売される。
【0020】
図3は直径の大きい太径缶等の筒状商品aを取り扱う場合であるが、この商品排出装置は直径の大きい太径缶等の筒状商品aから直径の小さい細径缶等の筒状商品aまで幅広く対応することができる。
【0021】
図4は、直径の小さい細径缶等の筒状商品aを取り扱う場合の例であり、この場合においても前述の場合と同様に第1および第2の係止体3a,3b,4a,4bの突没動作によりその最下層のものから順次1個ずつ排出される。
【0022】
ところで、太径の筒状商品aの場合には、その直径が大きいから最下層のものと次層のものとの接触点のレベル位置が高く、細径の筒状商品aの場合には、その直径が小さいから最下層のものと次層のものとの接触点のレベル位置が低くなる。
【0023】
そして、細径の筒状商品aの場合においては、その直径が小さいために次層の筒状商品aが排出通路2の片側に偏って配置することになり、販売動作時に第2の係止体4bが突出する際に、次層の筒状商品aを排出通路2の中央側に押し出すことになる。
【0024】
ところがこの際、次層の筒状商品aの上に配置する下から第3層目の筒状商品aが次層の筒状商品aの反対側の片側に偏って斜め上方に千鳥状に配置していると、販売動作時に第2の係止体4bがガイドプレート1bから突出して次層の筒状商品aを排出通路2の中央側に押し出そうとするときに、その次層の筒状商品aの動きがその上に千鳥状に配置する第3層目の筒状商品aにより阻まれ、係止体4bが適正に動作することが困難となり、筒状商品aの排出を達成できなくなるような事態が生じてしまう。
【0025】
そこで本出願人は、図3および図4に示すように排出通路2内に金属や合成樹脂からなる板ばね状の案内部材11を設け、コラムから排出通路2内に細径の筒状商品aが導入されるときに、この案内部材11で各筒状商品aを駆動源をもたないガイドプレート1b側に弾性的に付勢して順次上下に整列して配列するようにした技術を提案し、既に特願2000−35904号として特許出願をしてある。
【0026】
筒状商品aを駆動源をもたないガイドプレート1b側に偏らせて整列させる理由は、一般に駆動源10もつ一方のガイドプレート1aには販売売切れ検知レバーが設けられ、この売切れ検知レバーにより排出通路2内の筒状商品aが他方の駆動源をもたないガイドプレート1b側に弾性的に付勢されているから、これに合わせて案内部材11により筒状商品aを駆動源をもたないガイドプレート1b側に偏らせて整列させているのである。
【0027】
売切れ検知レバーは売切れ検知スイッチ等の電気部品を備えており、このため電気部品である駆動源10が設けられている一方のガイドプレート1aに設けることが組立上や保守上の点で有利であり、したがって売切れ検知レバーは駆動源10をもつガイドプレート1a側に設けられている。
【0028】
細径の筒状商品aの場合、前述したように販売動作時にガイドプレート1bにおける第2の係止体4bが鎖線で示すように排出通路2内に突出して次層の筒状商品aを排出通路2の中央側に押し出すことになり、したがってこの係止体4bには大きな負荷がかかる。
【0029】
ここで、一方のガイドプレート1aにおいては、駆動源10をもち、この駆動源10でその係止体3a,4aを直接駆動するからその動作時の動力は大きい。これに対し、他方のガイドプレート1bにおいては、駆動源をもたず、その係止体3b,4bには、一方のガイドプレート1aにおける係止体3a,4aの動力がカムやギアを用いる連動機構を通して伝達され、このため他方のガイドプレート1bにおける係止体3b,4bの動作時の動力は、連動機構で生じる摩擦等の損失により一方のガイドプレート1aにおける係止体3a,4aの動作時の動力より小さくなる。
【0030】
したがって、上述のように他方のガイドプレート1bにおける従動側の係止体4bが次層の筒状商品aに突き当たってそれを排出通路2の中央側に押し出すことになると、動力が不足し、その押し出しが達成されなかったり、動作がロックされてしまうような事態が生じ、筒状商品aを適正に排出することができなくなる恐れがある。
【0031】
この発明はこのような点に着目してなされたもので、その目的とするところは、細径の筒状商品を取り扱う場合であっても、動作の円滑性を常に良好に保ってその筒状商品を適正に排出させることができる自動販売機の商品排出装置を提供することにある。
【0032】
【課題を解決するための手段】
この発明はこのような目的を達成するために、互いに対向し、その対向間をコラムから導入される筒状商品の排出通路となす一対のガイドプレートを有し、これらガイドプレートには、それぞれ基部を中心にして回動することにより排出通路に向かって交互に突没する第1および第2の商品係止用の係止体が設けられ、前記一方のガイドプレートにはこのガイドプレートにおける各係止体を直接駆動する駆動源が設けられ、この駆動源で駆動される前記各係止体の動力を前記他方のガイドプレートにおける各係止体に伝達して動作させる連動機構が設けられ、排出通路内には筒状商品が前記他方のガイドプレート側に偏って整列するように弾性的に付勢する案内部材が設けられ、商品の販売待機時には前記駆動源に基づいて排出通路内に突出する前記第1の係止体により排出通路内の最下層の筒状商品が係止され、商品の販売時には第1の係止体の没入動作で最下層の筒状商品が下方に排出されるとともに、第2の係止体の突出動作で最下層の上の次層の筒状商品がその第2の係止体により係止され、こののち第1の係止体が突出し、第2の係止体が没入することにより前記次層の筒状商品が第2の係止体から離脱して下方に移動するとともに、第1の係止体により係止されて販売待機状態となる自動販売機の商品排出装置において、前記一方のガイドプレートにおける第2の係止体の長さをL、前記他方のガイドプレートにおける第2の係止体の長さをLとしたときに、これらL,Lの関係がL>Lの関係となるようにしたものである。
【0033】
そして、請求項2の発明においては、一方のガイドプレートにおける第2の係止体の長さLと、他方のガイドプレートにおける第2の係止体の長さLとの差が5〜10mmであることを特徴としている。
【0034】
【発明の実施の形態】
以下、この発明の一実施形態について図1および図2を参照して説明する。なお、図3および図4に示す構成と対応する部分には図面に同一の符号を付してその説明を省略する。
【0035】
この実施形態の商品排出装置においては、駆動源10をもつガイドプレート1aにおける駆動側の第2の係止体4aと、駆動源をもたないガイドプレート1aにおける従動側の第2の係止体4aとの長さの寸法が異なっている。
【0036】
すなわち、駆動側の係止体4aはその支軸5から先端部までの長さがL、従動側の係止体4bはその支軸5から先端部までの長さがLで、これら長さL,LがL>Lの関係となっている。具体的には、駆動側の係止体4aの長さLと、従動側の係止体4bの長さLとの差(L−L)を5〜10mmとする。 さらに説明を加えると、駆動側の係止体4aの長さLは、図3、図4に示す駆動側の係止体4aの長さより大きく、従動側の係止体4bの長さLは、図3、図4に示す従動側の係止体4bの長さより小さくなっており、この実施形態においてはその長さの差(L−L)が8mmとなっている。
【0037】
そして前述の構成の場合と同様に、駆動側の各係止体3a,4aは駆動源10により直接駆動されて動作し、従動側の各係止体3b,4bはカムやギアを用いる連動機構(図示せず)により伝達される駆動側の係止体3a,3bの動力により動作するようになっている。
【0038】
図1は、細径の筒状商品aを販売する場合の例で、図1(A)は販売待機時の状態を、図1(B)は排出動作時の状態を示してある。
【0039】
販売待機時においては、排出通路2内に導入された最下層の筒状商品aが第1の係止体3a,3bにより支持され、この最下層の上の後続の筒状商品aが案内部材11による弾性的な付勢力でガイドプレート1b側に偏って整列するように配置している。
【0040】
この販売待機状態から駆動源10に所定の信号が投入されると、第1の係止体3a,3bが外側に回動してガイドプレート1a,1bの背面側に没入するとともに、第2の係止体4a,4bが内側に回動してガイドプレート1a,1bの表面側に突出し、斜め上方に向かって傾斜する姿勢となる。この動作はほぼ瞬間的に行なわれる。
【0041】
そして第1の係止体3a,3bの没入動作で図2(B)に示すように、最下層の筒状商品aが下方に落下して排出され、また第2の係止体4a,4bの突出動作で次層の筒状商品aが支持される。
【0042】
従動側の第2の係止体4bが突出するときには、この係止体4bの長さLが短いため、図1(A)に鎖線で示すように次層の筒状商品aの下側に突出してその筒状商品aに突き当たるようなことがない。すなわち、係止体4bは筒状商品aの負荷を受けることがない。
【0043】
従動側の係止体4bは、前述したように駆動側の係止体4aに比べ動作時の動力が小さいが、筒状商品aの負荷を受けることがないから、動作ロック等を起こすことなく的確かつ円滑に回動動作して排出通路2内に突出する。
【0044】
そして従動側の係止体4bが突出した後に、この従動側の係止体4bと駆動側の係止体4aとで次層の筒状商品aが支持される。
【0045】
最下層の筒状商品aの排出後には、第1の係止体3a,3bが内側に回動してガイドプレート1a,1bの表面側に突出するとともに、第2の係止体4a,4bが外側に回動してガイドプレート1a,1bの背面側に没入し、この没入動作で次層の筒状商品aが下方に移動し、図1(A)に示すように第1の係止体3a,3bにより受け止められ、当初の販売待機状態となる。
【0046】
図2は、太径の筒状商品aを販売する場合の例で、図2(A)は販売待機時の状態を、図2(B)は排出動作時の状態を示してある。
【0047】
この場合においては、細径の筒状商品aの場合と同様に最下層の筒状商品aが第1の係止体3a,3bにより支持される。そして最下層の筒状商品aのほぼ直上に後続の筒状商品aが整列して積み重なる。
【0048】
この販売待機状態から駆動源10に所定の信号が投入されると、第1の係止体3a,3bが外側に回動してガイドプレート1a,1bの背面側に没入するとともに、第2の係止体4a,4bが内側に回動してガイドプレート1a,1bの表面側に突出する。
【0049】
そして第1の係止体3a,3bの没入動作で図2(B)に示すように、最下層の筒状商品aが下方に落下して排出され、これに伴い次層の筒状商品aが下方に移動する。この際、排出通路2内には係止体4a,4bが突出しているが、一方の駆動側の係止体4aの長さが長く、他方の従動側の係止体4bの長さが短い関係にあるから、次層の筒状商品aはその移動に伴い図2(B)に示すように駆動側の第2の係止体4aとガイドプレート1bとで支持され、従動側の係止体4bには接触しない。
【0050】
すなわち、太径の筒状商品aの場合には、動力の大きい駆動側の係止体4aで筒状商品aを受け止め、動力の小さい従動側の係止体4bには筒状商品aの負荷がかからず、このためその分、動作の円滑性が高まる。
【0051】
次層の筒状商品aが駆動側の係止体4aとガイドプレート1bとで支持された後には、第1の係止体3a,3bが内側に回動してガイドプレート1a,1bの表面側に突出するとともに、第2の係止体4a,4bが外側に回動してガイドプレート1a,1bの背面側に没入し、この没入動作で次層の筒状商品aが下方に移動し、図2(A)に示すように第1の係止体3a,3bにより受け止められ、当初の販売待機状態となる。
【0052】
このように、駆動側の係止体4aの長さLと従動側の係止体4bの長さLとの関係をL>Lとすることにより、商品排出時の動作の円滑性を高めることができる。そして駆動側の係止体4aの長さLと、従動側の係止体4bの長さLとの差(L−L)を5〜10mmに設定することにより、市場で一般に流通する直径の大きい太径の筒状商品aから直径の小さい細径の筒状商品aまで幅広く対応することができる。
【0053】
【発明の効果】
以上説明したようにこの発明によれば、直径の大きい太径の筒状商品から直径の小さい細径の筒状商品まで幅広く対応することができるとともに、そのいずれの場合であっても、特に細径の筒状商品を扱う場合であっても、動作の円滑性を常に良好に保って適正に排出させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a product discharge device for a vending machine that sequentially discharges cylindrical products such as plastic bottles and cans containing beverages one by one.
[0002]
[Prior art]
In a vending machine that sells cylindrical products such as plastic bottles and cans containing beverages, for example, serpentine columns are arranged in the cabinet as front and rear, left and right as product storage devices, and predetermined cylinders are placed in these columns. Goods are stacked and stored.
[0003]
A product discharge device is provided at the bottom of each column, and the product discharge devices discharge the cylindrical products in each column one by one from the bottom layer.
[0004]
The product discharge device locks the discharge passage through which the tubular product introduced from the column passes and the tubular product introduced into the discharge passage, and releases the lock in response to a predetermined signal. And a product discharge mechanism for dropping the product to drop downward. Conventionally, the width of the discharge passage through which the tubular product is passed is defined as a width that matches the outer diameter of the tubular product.
[0005]
By the way, the products sold by the vending machine are usually changed according to the season, sales, and the like, and the outer diameter of the cylindrical product varies depending on the change. Therefore, it is necessary to adjust the product discharge device so as to match the outer diameter of the changed tubular product.
[0006]
Generally, the product discharge passage is composed of a fixed wall unit and a movable wall unit facing the fixed wall unit, and the fixed wall unit is provided with a product discharge mechanism. Then, when the product is changed, the movable wall unit is moved so that the distance between the facing of the movable wall unit and the fixed wall unit, that is, the width of the discharge passage matches the outer diameter of the product after the change. It is adjusted to.
[0007]
However, such adjustment work must be carried out in a narrow space below the column with the operator putting his hand in a groping state, which is cumbersome and cumbersome, and the position of movement of the movable wall unit is also difficult. Visual confirmation is not possible, and wrong settings are often made.
[0008]
Also, when a cylindrical product with a large outer diameter is stored in one column, the width of the product discharge passage between the fixed wall unit and the movable wall unit depends on the outer diameter due to the cylindrical product with a large outer diameter. Since it is set to a large width and the state is maintained, when a cylindrical product with a large outer diameter is put in and stored in the column, it is mixed with the cylindrical product with a large outer diameter and the outer diameter is smaller than that. When a cylindrical product is mixed in by mistake, there is a risk that the cylindrical product having a small outer diameter passes through a wide discharge passage and is erroneously discharged.
[0009]
Therefore, the present applicant arranges a guide plate having a pair of retractable locking bodies for locking the product so that the locking bodies face each other, and the locking bodies of the respective guide plates are synchronized with each other. A product ejecting device for projecting and ejecting cylindrical products one by one in order is proposed, and a patent application has already been filed as Japanese Patent Application No. 2000-275374.
[0010]
In this product discharge device, a plurality of types of cylindrical products having different diameters can be locked and discharged as required without requiring adjustment work by an operator.
[0011]
FIG. 3 shows a schematic configuration of the product discharge device. The product discharge device has a pair of guide plates 1a and 1b that face each other and form a discharge passage 2 for the tubular product a between the opposed portions. The guide plates 1a and 1b are respectively provided with first and second pairs of locking bodies 3a, 3b, 4a and 4b which are positioned one above the other and project alternately into and out of the discharge passage 2. Yes.
[0012]
Each of the locking bodies 3a, 3b, 4a, 4b has a flapper shape, and a base portion at one end thereof is supported via a support shaft 5 installed on the guide plates 1a, 1b, and rotates around the support shaft 5. It moves so as to project into and out of the discharge passage 2. A cylindrical product a is introduced into the discharge passage 2 from a column (not shown), and the lowermost cylindrical product a is supported by the first pair of locking bodies 3a and 3b. .
[0013]
The support shaft 5 supporting the locking body 3a and the support shaft 5 supporting the locking body 3b are at the same level, and the length dimension from the support shaft 5 to the tip of the locking bodies 3a and 3b is as follows. It is almost the same.
[0014]
Further, the support shaft 5 supporting the locking body 4a and the support shaft 5 supporting the locking body 4b are at the same level, and the length from the support shaft 5 to the distal ends of the locking bodies 3a and 3b. The dimensions are almost the same.
[0015]
A drive source 10 such as a solenoid is provided on the back surface of one guide plate 1a, and the locking bodies 3a and 4a in the one guide plate 1a are directly driven by the drive source 10 to rotate. The operation of the stopping bodies 3a, 4a is transmitted to the locking bodies 3b, 4b in the other guide plate 1b via an interlocking mechanism (not shown) using cams or gears, and thereby the locking body in one guide plate 1a. 3a, 4a and the locking bodies 3b, 4b in the other guide plate 1b are projected and retracted symmetrically and substantially synchronously with each other.
[0016]
When a predetermined signal is input to the drive source 10 from the merchandise standby state shown in FIG. 3A, the drive source 10 drives the first pair of latches as shown in FIG. 3B. The bodies 3a and 3b are respectively rotated outward to be immersed in the back side of the guide plates 1a and 1b, and the second pair of locking bodies 4a and 4b are rotated inward to be surfaces of the guide plates 1a and 1b. Protrudes to the side. That is, the first pair of locking bodies 3a and 3b are opened to each other, and the second pair of locking bodies 4a and 4b are closed to each other.
[0017]
Then, in response to the immersing operation of the first locking bodies 3a, 3b, the lowermost cylindrical product a in the discharge passage 2 falls and discharges under its own weight, and the next layer above the lowermost layer. The cylindrical product a is supported from the lower side by the second locking bodies 4a and 4b.
[0018]
Then, after the lowermost tubular product a is discharged, the first locking bodies 3a and 3b rotate inward to return to the closed state, and the second locking bodies 4a and 4b rotate outward. It opens by moving, and in this opening operation, the cylindrical product a in the next layer falls downward and is supported by the first pair of locking bodies 3a, 3b in the closed state, and enters into a sales standby state. In addition, the projecting and retracting operations of the respective locking bodies 3a, 3b, 4a, 4b are performed almost instantaneously.
[0019]
In this way, each time a predetermined signal is input to the drive source 10, the cylindrical products a in the discharge passage 2 are discharged one by one from the lower layer side, and this is used by the vending machine through the sales outlet. Sold to
[0020]
FIG. 3 shows a case where a cylindrical product a such as a large-diameter can with a large diameter is handled. This product discharge device is a cylindrical product such as a small-diameter can with a small diameter from a cylindrical product a such as a large-diameter can with a large diameter. A wide range of products a can be handled.
[0021]
FIG. 4 is an example in the case of handling a cylindrical product a such as a thin can with a small diameter. In this case as well, the first and second locking bodies 3a, 3b, 4a, 4b are the same as in the case described above. Are ejected one by one from the lowest layer by the plunging operation.
[0022]
By the way, in the case of the thick cylindrical product a, the level position of the contact point between the bottom layer and the next layer is high because the diameter is large, and in the case of the thin cylindrical product a, Since the diameter is small, the level position of the contact point between the lowest layer and the next layer is low.
[0023]
In the case of the cylindrical product a having a small diameter, since the diameter thereof is small, the cylindrical product a in the next layer is arranged to be biased to one side of the discharge passage 2, and the second locking is performed during the sales operation. When the body 4b protrudes, the cylindrical product a of the next layer is pushed out to the center side of the discharge passage 2.
[0024]
However, in this case, the third-layer cylindrical product a is arranged on the opposite side of the next-layer cylindrical product a from the lower side to be arranged on the next-layer cylindrical product a, and is arranged in a staggered manner obliquely upward. When the second locking body 4b protrudes from the guide plate 1b during the sales operation and tries to push the cylindrical product a of the next layer toward the center of the discharge passage 2, the cylinder of the next layer The movement of the cylindrical product a is hindered by the third-layer cylindrical product a arranged in a staggered pattern thereon, making it difficult for the locking body 4b to operate properly, and discharging the cylindrical product a can be achieved. A situation will occur that will disappear.
[0025]
Therefore, the present applicant provides a leaf spring-shaped guide member 11 made of metal or synthetic resin in the discharge passage 2 as shown in FIGS. 3 and 4, and a small-diameter cylindrical product a from the column to the discharge passage 2. When this is introduced, a technique is proposed in which each cylindrical product a is elastically urged toward the guide plate 1b side having no drive source by the guide member 11 so as to be sequentially aligned vertically. A patent application has already been filed as Japanese Patent Application No. 2000-35904.
[0026]
The reason for aligning the cylindrical product a by being biased toward the guide plate 1b without the drive source is generally provided with a sold-out detection lever on one guide plate 1a of the drive source 10, and is discharged by this sold-out detection lever. Since the cylindrical product a in the passage 2 is elastically urged toward the guide plate 1b side having no other drive source, the guide member 11 has the cylindrical product a as a drive source. The guide plate 1b is not biased and aligned.
[0027]
The sold-out detection lever includes electrical parts such as a sold-out detection switch. For this reason, it is advantageous in terms of assembly and maintenance to be provided on one guide plate 1a provided with the drive source 10 which is an electrical part. Therefore, the sold-out detection lever is provided on the side of the guide plate 1 a having the drive source 10.
[0028]
In the case of the small-diameter cylindrical product a, as described above, the second locking body 4b of the guide plate 1b protrudes into the discharge passage 2 as shown by the chain line during the sales operation and discharges the next-layer cylindrical product a. It will push out to the center side of the channel | path 2, Therefore A big load is applied to this latching body 4b.
[0029]
Here, one of the guide plates 1a has a driving source 10, and the driving source 10 directly drives the locking bodies 3a and 4a, so that the power during the operation is large. On the other hand, the other guide plate 1b does not have a drive source, and the locking bodies 3b and 4b are interlocked with the power of the locking bodies 3a and 4a in the one guide plate 1a using cams or gears. Therefore, the power during operation of the locking bodies 3b and 4b in the other guide plate 1b is transmitted during the operation of the locking bodies 3a and 4a in one guide plate 1a due to loss of friction or the like generated in the interlocking mechanism. It becomes smaller than the power of.
[0030]
Therefore, as described above, when the driven side locking body 4b in the other guide plate 1b hits the cylindrical product a of the next layer and pushes it to the center side of the discharge passage 2, the power is insufficient, There is a possibility that the extrusion is not achieved or the operation is locked, and the tubular product a cannot be properly discharged.
[0031]
The present invention has been made paying attention to such points, and the object of the present invention is to keep the smoothness of the operation always good even when handling a thin cylindrical product. An object of the present invention is to provide a product discharge device for a vending machine capable of properly discharging a product.
[0032]
[Means for Solving the Problems]
In order to achieve such an object, the present invention has a pair of guide plates that are opposed to each other and that serve as a discharge passage for a cylindrical product introduced from a column between the opposed portions. The first and second locking members for locking the product alternately projecting and retracting toward the discharge passage by rotating about the center of the guide plate. A drive source for directly driving the stop body is provided, and an interlocking mechanism is provided for transmitting the power of each lock body driven by this drive source to each lock body in the other guide plate for operation. A guide member is provided in the passage to elastically bias the cylindrical product so that it is aligned with the other guide plate. The product protrudes into the discharge passage based on the drive source when the product is on sale. The lowermost cylindrical product in the discharge passage is locked by the first locking body, and when the product is sold, the lowermost cylindrical product is discharged downward by the immersing operation of the first locking body. At the same time, the cylindrical product in the next layer above the lowermost layer is locked by the second locking body by the protruding operation of the second locking body, and then the first locking body protrudes, When the locking body is submerged, the cylindrical product of the next layer is detached from the second locking body and moves downward, and is locked by the first locking body to enter a sales standby state. In the product discharge device of the machine, when the length of the second locking body in the one guide plate is L 1 and the length of the second locking body in the other guide plate is L 2 , The relationship between L 1 and L 2 is such that L 1 > L 2 .
[0033]
Then, in the invention of claim 2, the length L 1 of the second locking member in one of the guide plate, the difference between the length L 2 of the second locking member in the other guide plate 5 It is characterized by being 10 mm.
[0034]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. Note that portions corresponding to those shown in FIGS. 3 and 4 are denoted by the same reference numerals, and description thereof is omitted.
[0035]
In the product discharge device of this embodiment, the second locking body 4a on the driving side in the guide plate 1a having the driving source 10 and the second locking body on the driven side in the guide plate 1a having no driving source. The length dimension is different from 4a.
[0036]
That is, the driving-side locking body 4a has a length L 1 from the support shaft 5 to the tip portion, and the driven-side locking body 4b has a length L 2 from the support shaft 5 to the tip portion. The lengths L 1 and L 2 have a relationship of L 1 > L 2 . Specifically, the length L 1 of the engaging body 4a of the driving side, the difference between the length L 2 of the engaging body 4b of the driven side (L 1 -L 2) and 5 to 10 mm. Further addition of explanation, the length L 1 of the engaging body 4a of the driving side, Figure 3, greater than the length of the engaging body 4a of the drive side shown in FIG. 4, the length of the engaging body 4b of the driven side L 2, 3, is smaller than the length of the engaging body 4b of the driven side shown in FIG. 4, the difference between the length (L 1 -L 2) is in the 8mm in this embodiment.
[0037]
As in the case of the above-described configuration, the driving-side locking bodies 3a, 4a are operated by being directly driven by the drive source 10, and the driven-side locking bodies 3b, 4b are interlocking mechanisms using cams or gears. It operates by the power of the driving side locking bodies 3a and 3b transmitted by (not shown).
[0038]
FIGS. 1A and 1B show an example of selling a thin cylindrical product a, FIG. 1A shows a state at the time of sales standby, and FIG. 1B shows a state at the time of discharging operation.
[0039]
At the time of sales standby, the lowermost cylindrical product a introduced into the discharge passage 2 is supported by the first locking bodies 3a and 3b, and the subsequent cylindrical product a on the lowermost layer is a guide member. 11 is arranged so as to be biased and aligned toward the guide plate 1b side by an elastic urging force.
[0040]
When a predetermined signal is input to the drive source 10 from this sales standby state, the first locking bodies 3a and 3b rotate outward to be immersed in the back side of the guide plates 1a and 1b, and the second The locking bodies 4a and 4b rotate inward to protrude to the surface side of the guide plates 1a and 1b, and are inclined obliquely upward. This operation is performed almost instantaneously.
[0041]
Then, as shown in FIG. 2B, the lowermost cylindrical product a is dropped and discharged by the immersing operation of the first locking bodies 3a and 3b, and the second locking bodies 4a and 4b. The cylindrical product a of the next layer is supported by the protruding operation.
[0042]
When the second engaging body 4b of the driven side protrudes, this for engaging body 4b of length L 2 is short, the lower side of the cylindrical items a follows layer as indicated by the chain line in FIG. 1 (A) And projecting into the tubular product a. That is, the locking body 4b does not receive the load of the cylindrical product a.
[0043]
As described above, the driven-side locking body 4b has less power during operation than the driving-side locking body 4a, but does not receive the load of the tubular product a, so that it does not cause an operation lock or the like. It rotates accurately and smoothly and protrudes into the discharge passage 2.
[0044]
After the driven-side locking body 4b protrudes, the next-layer cylindrical product a is supported by the driven-side locking body 4b and the driving-side locking body 4a.
[0045]
After the lowermost tubular product a is discharged, the first locking bodies 3a and 3b rotate inward to protrude to the surface side of the guide plates 1a and 1b, and the second locking bodies 4a and 4b. Turns outward and immerses into the back side of the guide plates 1a and 1b, and this immersing operation moves the cylindrical product a in the next layer downward, as shown in FIG. 1 (A). It is received by the bodies 3a and 3b and enters the initial sales standby state.
[0046]
FIGS. 2A and 2B are examples in the case of selling a large-diameter cylindrical product a, FIG. 2A shows a state in a standby state, and FIG. 2B shows a state in a discharging operation.
[0047]
In this case, the lowermost tubular product a is supported by the first locking bodies 3a and 3b as in the case of the thin tubular product a. Then, the subsequent cylindrical products a are aligned and stacked almost directly above the lowermost cylindrical product a.
[0048]
When a predetermined signal is input to the drive source 10 from this sales standby state, the first locking bodies 3a and 3b rotate outward to be immersed in the back side of the guide plates 1a and 1b, and the second The locking bodies 4a and 4b rotate inward and protrude to the surface side of the guide plates 1a and 1b.
[0049]
Then, as shown in FIG. 2 (B), the lowermost cylindrical product a is dropped and discharged by the immersing operation of the first locking bodies 3a, 3b. Moves downward. At this time, the locking bodies 4a and 4b protrude into the discharge passage 2, but the length of one driving-side locking body 4a is long and the other driven-side locking body 4b is short. As shown in FIG. 2 (B), the cylindrical product a in the next layer is supported by the second locking body 4a on the driving side and the guide plate 1b as it moves, and is locked on the driven side. It does not contact the body 4b.
[0050]
That is, in the case of a large-diameter cylindrical product a, the cylindrical product a is received by the locking member 4a on the driving side with large power, and the load on the cylindrical product a is loaded on the locking member 4b on the driven side with small power. Therefore, the smoothness of the operation is increased accordingly.
[0051]
After the next-layer cylindrical product a is supported by the driving-side locking body 4a and the guide plate 1b, the first locking bodies 3a and 3b are rotated inwardly to surface the guide plates 1a and 1b. And the second locking bodies 4a and 4b rotate outward to be immersed in the back side of the guide plates 1a and 1b, and the cylindrical product a in the next layer moves downward by this immersion operation. As shown in FIG. 2 (A), it is received by the first locking bodies 3a and 3b, and enters the initial sales standby state.
[0052]
Thus, by the relationship between the length L 2 of the engaging body 4b length L 1 and the driven side of the engaging body 4a of the driving side and L 1> L 2, smooth operation during product discharge Can increase the sex. And the length L 1 of the engaging body 4a of the driving side, the difference between the length L 2 of the engaging body 4b of the driven side (L 1 -L 2) by setting the 5 to 10 mm, in general in the market A wide range from a large-diameter cylindrical product a having a large diameter to a small-diameter cylindrical product a having a small diameter can be handled.
[0053]
【The invention's effect】
As described above, according to the present invention, it is possible to deal with a wide range from a large-diameter cylindrical product having a large diameter to a small-diameter cylindrical product having a small diameter. Even in the case of handling a cylindrical product having a diameter, the smoothness of the operation can always be kept good and the product can be discharged properly.
