Abstract

<P>PROBLEM TO BE SOLVED: To squash an empty can with small force, and to suppress electric power consumption of a motor. <P>SOLUTION: An empty can thrown from a throwing port slides down a guide section 8 and drops into one concave section of a female rotary roller 12. A male rotary roller 11 and the female rotary roller 12 rotate in such a way that they sandwich the empty can and wind it up in directions opposite to each other. Thus, the male and female rotary rollers 11 and 12 press the empty can, while rotating, so that the pressure is given to the can at a pressing place between the empty can and ridge sections formed spirally along peripheral surfaces of a convex section and the concave section, respectively. Here, the pressure applied to the empty can in an oblique direction against a can axis has a component along the axis, and then the can is squashed in a state of being shifted, to be easily compressed into a flat shape. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
この発明は、例えば、缶ジュースや缶ビール等の飲用缶の飲用後の空缶を潰して容積の縮小化処理を行う空缶潰圧装置に関する。
【0002】
【従来の技術】
近年は、ジュースやビール等の飲料を小型の金属缶(例えばアルミニウム缶)に詰めた缶飲料が広く流通しており、人が多く集まる場所には、屋内、屋外を問わず、これらの缶飲料の自動販売機が多数設置されている。
通常、飲用後の空缶は、自動販売機のそばに設けた空缶入れに入れて、回収するようになされているが、空缶入れがすぐに空缶で一杯となってしまい、美観上も好ましくないという問題があった。
このため、空缶を潰してコンパクト化して収納しておくようにした装置が提案されている。
例えば、空缶の軸に直交する方向に押圧力を加えて空缶を潰したり(例えば、特許文献1参照。)、空缶の軸に沿った方向に押圧力を加えて空缶を潰して(例えば、特許文献2参照。)、コンパクト化して回収することが行われている。

【発明が解決しようとする課題】
しかしながら、上記従来技術では、空缶を一度に潰そうとする場合に、空缶の軸に沿った方向に押圧力を加えて空缶を潰そうとすると、胴部が支えとなって、簡単に潰すことができず、また、軸に直交する方向に押圧力を加えて空缶を潰そうとすると、蓋部の強度のために簡単に潰すことができず、いずれにしても完全に潰すことが困難であるという問題があった。

【0018】
【発明の実施例】
次に、図面を参照して、この発明の実施例について説明する。
◇第1実施例
図1は、この発明の第1実施例である空缶潰圧装置の概略構成を示す斜視図、図2は、同空缶潰圧装置の内部の概略構成を示す斜視図、図3は同空缶潰圧装置の缶プレス部の要部の構成を示す斜視図、図4は、同缶プレス部の雄型回転ローラの概略構成を示す正面図、図5は、同雄型回転ローラ及び雌型回転ローラの概略構成を示す側面図、図6は、同雄型回転ローラ及び雌型回転ローラの概略構成を示す断面図、また、図7乃至図10は、同空缶潰圧装置の動作を説明するための説明図である。
この例の空缶潰圧装置1は、例えばアルミ缶入りの飲料が販売される自動販売機の傍らに配置され、図1及び図2に示すように、筐体2と、空缶が投入される缶投入部3と、投入された空缶を潰圧して圧縮変形させる缶プレス部4(ずれ応力発生機構、ずれ/圧縮応力発生機構)と、潰圧された空缶を収納する缶収納部5とを備えてなっている。
【0019】
缶投入部3は、筐体2を構成する上部筐体6に設けられた投入口7から投入された空缶を缶プレス部4の圧接部位へ導く案内部8を有している。
缶プレス部4は、筐体2を構成する中部筐体9内に収容され、空缶を間に挟み込んで潰圧する1対の雄型回転ローラ(第1又は第2の回転ローラ)11及び雌型回転ローラ(第2又は第1の回転ローラ)12と、雄型回転ローラ11を駆動するためのモータ(駆動手段)10とを備えている。
また、雄型回転ローラ11及び雌型回転ローラ12の両側端には、互いに噛合するギア(第1又は第2の歯車)13,13及びギア(第2又は第1の歯車)14,14がそれぞれ固定され、一方の歯車13が、モータ10によって、モータギア15,回転ギア16を介して回転することによって回転し、ギア14へ動力を伝達するように構成されている。
これによって、雄型回転ローラ11及び雌型回転ローラ12は、空缶を挟んで互いに反対の向きに空缶を巻き込むように同一の回転数で回転する。
【0020】
また、雄型回転ローラ11は、図2乃至図5に示すように、その軸が中部筐体9の側壁部に固定された緩衝機能を有する支持腕17によって支持され、雌型回転ローラ12は、その軸が中部筐体9の底板部に固定された支持柱18によって支持されている。
雄型回転ローラ11及び雌型回転ローラ12は、支持腕17及び支持柱18によって、軸同士が平行な状態で相対峙するように配置されている。
雌型回転ローラ12には、図5及び図6に示すように、この雌型回転ローラ12の軸に空缶の軸が平行に配置される状態で空缶を保持するための複数(この例では、5つ)の半円筒形状の凹状湾曲部(凹面部)21が形成され、雄型回転ローラ11には、凹状湾曲部21に保持された空缶を押圧するための凹状湾曲部21の形状に対応した形状を有する複数(この例では、5つ)の半円筒形状の凸状湾曲部(凸面部)22が形成されている。
【0021】
雄型回転ローラ11及び雌型回転ローラ12の回転によって、凸状湾曲部22が、凹状湾曲部21との間に予め設定された所定の幅の間隙が形成されるように凹状湾曲部21内に配置されるように、雄型回転ローラ11及び雌型回転ローラ12が配置されている。
凸状湾曲部22及び凹状湾曲部21には、図3乃至図5に示すように、その周面に沿って、複数巻きの螺旋溝がそれぞれ形成され、螺旋溝によって挟まれた領域は、それぞれ押圧用山部23,24とされ、雄型回転ローラ11及び雌型回転ローラ12部が、回転しながら空缶に圧接することによって、押圧用山部23,24と空缶との圧接部位で、空缶に対して押圧力が与えられる。
ここで、空缶には、その軸に対して斜め方向に、軸に沿った方向の成分を持つ押圧力が加えられる。すなわち、空缶に働く力は、空缶を押し潰すように空缶の軸に向かう分力と、空缶の軸に沿った方向に働く分力と、両分力の方向に直交し、空缶を回転させるように働く分力とが合成されたものとなる。
【0022】
なお、この例では、雄型回転ローラ11及び雌型回転ローラ12は、雄型回転ローラ11の凸状湾曲部22に形成された押圧用山部23と、雌型回転ローラ12の凹状湾曲部21に形成された押圧用山部24とは、上方から見て、雄型回転ローラ11の凸状湾曲部22に形成された押圧用山部23と、雌型回転ローラ12の凹状湾曲部21に形成された押圧用山部24とが、略平行となるように、配置されている。
これによって、雄型回転ローラ11及び雌型回転ローラ12の回転によって、空缶に対して加えられる押圧力の空缶の軸に沿った方向の分力の向きが互いに反対となる。
缶収納部5は、図1及び図2に示すように、筐2を構成する下部筐体26内に回収箱27がレール28によって案内されて引出可能なように配置されてなっている。なお、下部筐体26の正面には、回収箱27を出入れするための扉29が設けられている。
【0023】
次に、図7乃至図10を参照して、この例の空缶潰圧装置1の動作について説明する。
投入口7から空缶Aが投入されると、図7(a)及び図8(a)に示すように、空缶Aは案内部8を滑り落ちて缶プレス部4の圧設部位(例えば、雌型回転ローラ12の1つの凹状湾曲部21内)に落下する。
次に、モータ10が回転し、その動力が雄型回転ローラ11及び雌型回転ローラ12に伝達されると、雄型回転ローラ11及び雌型回転ローラ12は、空缶Aを挟んで互いに反対の向きに空缶Aを巻き込むように同一の回転数で回転する。
【0024】
これによって、図7(b)及び図8(b)に示すように、雄型回転ローラ11及び雌型回転ローラ12部が、回転しながら空缶Aに圧接することによって、押圧用山部23,24と空缶Aとの圧接部位で、空缶Aに対して押圧力が与えられる。
空缶Aは、その胴部の周面の相対向する側の部位で、互いに反対向きの矢印X,Xで示す方向にずらされ、平面視で、辺a,b,c,dによって囲まれた略矩形状の空缶A(図8(a)参照)は、高さが小さくなった平行四辺形状の空缶Aとなる(図8(b)参照)。
このように、凹状湾曲部21に保持された空缶Aは、凸状湾曲部22によって押圧されて、少しずつ圧縮変形する。
ここで、空缶Aには、その軸に対して斜め方向に、軸に沿った方向の成分を持つ押圧力が加えられる。すなわち、図9に示すように、空缶Aに働く力F,Fは、空缶Aを押し潰すように缶の軸に向かう分力と、空缶Aの軸に沿った方向に働く分力と、両分力の方向に直交し、空缶を回転させるように働く分力とが合成されたものとなる。
また、空缶Aに対して、雄型回転ローラ11側から加えられる押圧力Fと雌型回転ローラ12側から加えられる押圧力Fとは、空缶Aの軸に沿った方向の分力が互いに反対向きである。
【0025】
このように、空缶Aには、その軸に対して斜め方向に押圧力F,Fが加わり、かつ、空缶Aに対して、雄型回転ローラ11側から加えられる押圧力Fと雌型回転ローラ12側から加えられる押圧力Fとは、空缶Aの軸に沿った方向の分力が互いに反対向きであるので、空缶Aにずれ変形が発生し、雄型回転ローラ11及び雌型回転ローラ12の回転と共に、図7(c)、図8(c)及び図10に示すように、空缶Aは、その胴部が扁平な形状に押し潰されると同時に、底部及び蓋部も扁平な胴部の方に曲げられる。
これによって、平面視で、図8(b)に示す平行四辺形状の空缶Aよりも、さらに高さが小さくなった空缶Aとなり、全体として、やや湾曲した扁平な形状に略完全に押し潰される。
ここで、凸状湾曲部22と凹状湾曲部21との間に形成されるの間隙の幅の大きさによって、潰圧の程度が調整される。
雄型回転ローラ11及び雌型回転ローラ12がさらに回転すると、図7(d)及び図8(d)に示すように、扁平な形状に潰圧された空缶Aは、雄型回転ローラ11及び雌型回転ローラ12から離れ、缶収納部5の回収箱27へ向けて落下する。
回収箱27に空缶Aが十分蓄積された場合は、扉29を開け、レール28に沿って回収箱27を引き出して取り出す。
【0026】
このように、この第1実施例の構成によれば、空缶Aにその軸に対して斜め方向に押圧力を加え、かつ、空缶Aに対して、雄型回転ローラ11側から加えられる押圧力と雌型回転ローラ12側から加えられる押圧力とは、空缶の軸に沿った方向の分力が互いに反対向きであるので、空缶Aにずれ変形を起こさせて潰すことができ、比較的小さな力でも簡単にかつ略完全に潰すことができる。
したがって、モータの消費電力を抑制することができる。また、一度の動作で迅速に空缶を潰すことができる。
しかも、簡易な構成とすることができるので、装置の小型化、軽量化及び低コスト化に寄与することができる。
【0027】
◇第2実施例
図11は、この発明の第2実施例である空缶潰圧装置の雄型回転ローラ及び雌型回転ローラの概略構成を示す平面図である。
この例の装置構成が、上記した第1実施例のそれと大きく異なるところは、凸状湾曲部及び凹状湾曲部の押圧用山部が上方から見て互いに略対称となるように、雄型回転ローラ及び雌型回転ローラが配置されている点である。
これ以外の構成は、上述した第1実施例の構成と略同一であるので、その説明を簡略にする。
【0028】
この例の空缶潰圧装置の雄型回転ローラ11A及び雌型回転ローラ12Aは、図11に示すように、上方から見て、雄型回転ローラ11Aの凸状湾曲部22Aに形成された押圧用山部23Aと、雌型回転ローラ12Aの凹状湾曲部21Aに形成された押圧用山部24Aとが、略対称となるように(すなわち、「ハ」の字を描くように)、配置されている。
【0029】
このように、この第2実施例の構成によれば、空缶Aに軸に対して斜め方向に押圧力を加えて潰すように構成されているので、比較的小さな力でも簡単にかつ略完全に潰すことができ、モータの消費電力を抑制することができる。
また、一度の動作で迅速に空缶を潰すことができる。
しかも、簡易な構成とすることができるので、装置の小型化、軽量化及び低コスト化に寄与することができる。
【0030】
以上、この発明の実施例を図面により詳述してきたが、具体的な構成はこの実施例に限られたものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があってもこの発明に含まれる。
例えば、上述した実施例では、アルミ缶を扱う場合について述べたが、これに限らず、スチール缶を扱っても良い。また、例えば、アルミ缶と、スチール缶や、内容物が残存している缶とを分別する分別手段を付加するようにしても良い。
また、雄型回転ローラや雌型回転ローラの軸は水平方向に沿っていなくても鉛直方向に沿って配置されていても斜め方向であっても良い。
【0031】
また、ずれ変形を発生させる押圧力を、空缶が投入され、雄型回転ローラと雌型回転ローラとの間に挟まれて変形が始まった直後の所定時間のみ与え、この後は、空缶の回転対称軸に直角な方向にのみ押圧力を与えるようにしても良い。
また、空缶に若干のずれ変形を発生させて(例えば、図8(b)参照)、圧縮変形容易とした状態で、空缶を、従来技術で述べたようなプレス装置に導入するようにしても良い。
さらに、空缶の回転対称軸に直角な方向に直接押圧力を加える機能を廃し、例えば、空缶の蓋部と底部とを押えた状態で、蓋部と底部とを同時に回転対称軸に対して傾けるようにして、主としてずれ変形を発生させる機能のみを備えた構成としても良い。
【0032】
また、例えば、雄型回転ローラ及び雌型回転ローラの空缶に接触する部位のうち、空缶の両端部(蓋部及び底部)に接触する部位のみに押圧用山部を形成して、空缶の両端部のみを押圧するようにしても良い。また、空缶の胴部の中央部のみを押圧するようにしても良い。
また、雄型回転ローラ及び雌型回転ローラは、一対とは限らず、複数対配置するようにしてもよい。
また、投入口の形状は空缶を軸方向に沿って投入可能なように円形の形状としても良いし、横にして投入可能なように矩形状としても良い。
【0033】
また、回転ローラは、両方雄型(凸型)でも良い。この場合、単に棒状部材に螺旋状の突起部が形成されたものであっても良い。このときは、飛び出さないように上方から空缶を押えるか、ゴム部材を棒状部材に被覆して摩擦力で送り出すようにしても良い。
また、複数対の棒状部材を配置して、排出側に近い棒状部材ほど両棒状部材間の間隙が狭くなるようにしても良い。
また、第1の実施例で述べた回転ローラの押圧用山部の少なくとも押圧面に、ゴム部材を取り付けるようにしても良い。
また、空缶を、その軸方向に潰すようにしても良い。また、螺旋状に形成する螺旋溝及び押圧用山部は、連続的でなくても良い。また、螺旋溝及び押圧用山部の巻数は、1巻きであっても良いし、1巻き以下であっても良い。
また、両回転ローラを別々のモータで回転させるようにしても良い。また、空缶の投入を検知して、モータを動作させるようにしても良い。また、人の接近を検知してモータを動作させるようにしても良い。
また、一方の回転ローラを必要に応じて固定させても良い。または、固定部と単一の回転ローラとの間に空缶を投入するようにしても良い。
【0034】
【発明の効果】
以上説明したように、この発明の構成によれば、ずれ応力発生機構によって、空缶にずれ変形を起こさせて、空缶を潰圧するように構成されているので、比較的小さな力でも空缶を簡単にかつ略完全に潰すことができ、例えば、駆動手段としてのモータの消費電力を抑制することができる。
また、ずれ/圧縮応力発生機構によって、空缶にずれ変形と圧縮変形とを起こさせて、空缶を潰圧するように構成されているので、比較的小さな力でも一段と簡単に空缶を潰すことができる。
また、一度の動作で迅速に空缶を潰すことができる。
しかも、簡易な構成とすることができるので、装置の小型化、軽量化及び低コスト化に寄与することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can crushing apparatus for crushing empty cans such as canned juice or canned beer after drinking to reduce the volume.
[0002]
[Prior art]
In recent years, canned beverages in which beverages such as juice and beer are packed in small metal cans (for example, aluminum cans) have been widely distributed, and in places where many people gather, these canned beverages can be used indoors or outdoors. Many vending machines are installed.
Normally, empty cans after drinking are put into an empty can provided near the vending machine and collected, but the empty can is quickly filled with empty cans. However, there is a problem that it is not preferable.
For this reason, there has been proposed a device in which an empty can is crushed to be compact and stored.
For example, a pressing force is applied in a direction perpendicular to the axis of the empty can to crush the empty can (for example, see Patent Document 1), or a pressing force is applied in a direction along the axis of the empty can to crush the empty can. (For example, see Patent Literature 2).

As a result, in plan view, the empty can A has a smaller height than the parallelogram-shaped empty can A shown in FIG. 8B, and as a whole, is almost completely pressed into a slightly curved flat shape. Crushed.
Here, the degree of the crushing pressure is adjusted by the width of the gap formed between the convex curved portion 22 and the concave curved portion 21.
When the male type rotating roller 11 and the female type rotating roller 12 further rotate, as shown in FIGS. 7 (d) and 8 (d), the empty can A crushed into a flat shape becomes the male type rotating roller 11 Then, it separates from the female rotary roller 12 and falls toward the collection box 27 of the can storage unit 5.
When the empty boxes A are sufficiently accumulated in the collection box 27, the door 29 is opened, and the collection box 27 is pulled out along the rail 28 and taken out.
