Description

【０００１】
【産業上の利用分野】
本発明は、高層ビルのごみ輸送装置用のごみ容器に係り、特に高層ビルの垂直輸送管に投入され、その垂直輸送管内をほぼ一定の落下速度で落下するように構成された高層ビルのごみ輸送装置用のごみ容器に関する。
【０００２】
【従来の技術】
高層ビルの各階から収集されたごみを地上に搬送する高層ビルのごみ輸送装置は、種々のタイプのものが開発されている。
【０００３】
図８は例えば特開平５−３２３０２号公報に記載された代表的な高層ビルのごみ輸送装置を示したもので、高層ビル１には各階を貫通する垂直輸送管２が設置され、この垂直輸送管２には各階にごみ投入装置３が付設されている。垂直輸送管２の下端には開閉可能な底蓋４が取り付けられ、この底蓋４は開閉シリンダ５によって開閉される。底蓋４の上方には、垂直輸送管２から空気を調整可能に排出する空気排出装置６と、垂直輸送管２内の圧力を検出する圧力検出装置７とがそれぞれ設置されている。また、垂直輸送管２は底蓋４の下方においてシュート８に連通され、このシュート８の下端には貯留槽９が接続され、ごみはこの貯留槽９に溜められた後に塵芥収集車１０に積込まれる。
【０００４】
ごみは、図９に示したように合成樹脂シート（ポリシート）等の軟質性円筒状のごみ容器１１に収容されてごみカート１２によってごみ投入装置３まで運ばれ、このごみ投入装置３から垂直輸送管２に投入される。ごみ容器１１の外径は、ごみが十分に収容された時に垂直輸送管２の内径よりも僅かに小くなるように定められており、従って、ごみ容器１１が垂直輸送管２内を落下した時に、ごみ容器１１と垂直輸送管２との間の間隙に比較的大きな空気抵抗が発生し、この空気抵抗によってごみ容器１１は所定の速度で落下する。
【０００５】
空気排出装置６と圧力検出装置７は、ごみ容器１１の落下速度をごみ容器１１の重量に無関係にほぼ一定に設定するためのものである。投入されたごみ容器１１が比較的軽量であるため垂直輸送管２の下部の圧力があまり高くない時には、その圧力を検出した圧力検出装置７の検出出力に基づき、空気排出装置６はごみ容器１１の下方の空気を比較的多量に排出して、ごみ容器１１の落下速度を加速する。他方、投入されたごみ容器１１が比較的重いため垂直輸送管２の下部の圧力が高い時には、その圧力を検出した圧力検出装置７の検出出力に基づき、空気排出装置６はごみ容器１１の下方の空気を比較的少量だけ排出して、ごみ容器１１の落下速度を減速する。こうして、投入されたごみ容器１１はその重量に無関係に、常にほぼ一定の速度でもって垂直輸送管２内を落下して底蓋４に軟着地する。
【０００６】
以上のように、上述の高層ビルのごみ輸送装置は、図１０に示されたようにごみ１３がある大きさ以下でかつほぼ均一に十分な量だけごみ容器１１に積込まれている場合には、ごみ容器１１の外径が垂直輸送管２の内径よりも僅かに小くなる。これによってごみ容器１１と垂直輸送管２との間の間隙がほぼ一定の小面積となり、この間隙を通過する空気抵抗が比較的大きくなるため、空気排出装置６の作用によってごみ容器１１をその重量に無関係にほぼ一定の速度で落下させることができる。
【０００７】
しかしながら、ごみ容器１１に収容されるごみが、束ねた新聞紙のような直方体などの非円筒形のブロックである場合には、ごみ容器１１は円筒状に形成されず、垂直輸送管２内の落下の際に、ごみ容器１１と垂直輸送管２の内壁との間隙がかなり大きくなり、この間隙を通過する空気の抵抗がごみ容器１１とバランスする程大きくならないため、ごみ容器１１の落下速度を制御することができず、ごみ容器１１は急降下し底蓋４に激突し、破裂し内部のごみが周囲に飛散するといった問題が発生する。
【０００８】
そこで、このような問題を解決するために、特開平４−３０３３０３号公報及び特開平５−３２３０２号公報には、図１１に示したように複数の空気孔１４が穿孔されたごみ容器１１が開示されている。このごみ容器１１は束ねた新聞紙のような非円筒形のブロックのごみ１３を収容し、垂直輸送管２を落下する時に、空気が矢印で示したように空気穴１４からごみ容器１１の内部に流入し、ごみ容器１１を外側に膨らましてちょうど落下傘のような形状にする。これによって、ごみ容器１１と垂直輸送管２の内壁との間隙がほぼ一定の小面積になり、ごみ容器１１の重量に拮抗する空気抵抗が発生し、ごみ容器１１の落下速度を減速する。こうして、空気孔１４が穿孔されたごみ容器１１は、非円筒形状のごみ１３を収容した場合にも、垂直輸送管内を所定の低速度で落下し、底蓋に軟着陸する。
【０００９】
更に、特開平５−３２３０２号公報には、ごみ容器内のごみの量が非常に少ない場合には、図１２に示したように空気孔１４を有するごみ容器１１の内部上部にごみ容器１１の内径よりもやや小径の円板体１５を挿入することが開示されている。この円板体１５の挿入によって、ごみの量が非常に少ない場合にも、ごみ容器１１は空気孔１４から流入した空気によって確実に外方に膨らむことができる。
【００１０】
【発明が解決しようとする課題】
ところが、上述の空気穴が穿孔されたごみ容器は、水分を多量に含有するごみ、例えば厨房などから発生した厨芥を収容した場合には、空気孔から汚水が漏出し、垂直輸送管の内部を汚染するといった問題に加え、収容するごみの量が少ない場合には円板体を内部に挿入しなければならないといった煩わしい作業を必要とする。
【００１１】
そこで、本発明の目的は、ごみの量が少量であっても、またごみの形状が非円筒状であっても、垂直輸送管内のごみ容器の落下速度を確実に低速度に制御することができ、かつ水分を多量に含有するごみも汚水の漏出なしに収容することができる高層ビルのごみ輸送装置用のごみ容器を提供することにある。
【００１２】

その口径が前記垂直輸送管の内径より僅かに小径な軟質性筒状シート材から構成された外筒と、
その口径が前記外筒の口径と同径若しくはわずかに小径な軟質性筒状シート材から構成された内筒と、を備え、

【００１４】
【作用】
請求項１に記載された発明の作用は以下の通りである。外筒と内筒は夫々の下端が互いに接合されているため、両下端の相対的位置関係を変えることなく垂直輸送管内を一体的に落下する。この落下時に、外筒下端の開口から、空気が外筒と内筒との間に流入する。この流入した空気は外筒を筒状に膨らませて、外筒と垂直輸送管の内壁との間の間隙を小さくする。これによって、ごみ容器は、外筒と垂直輸送管の内壁との間隙を流れる空気の抵抗によって減速される。
【００１５】
請求項４に記載された発明の作用は以下の通りである。外筒と内筒は夫々の下部が互いに断続的に接合されているため、両下端の相対的位置関係を変えることなく垂直輸送管内を一体的に落下する。この落下時に、断続的な接合部の間に形成された外筒と内筒との間隙から、空気が外筒と内筒との間に流入する。この流入した空気は外筒を筒状に膨らませて、外筒と垂直輸送管の内壁との間の間隙を小さくする。これによって、ごみ容器は、外筒と垂直輸送管の内壁との間隙を流れる空気の抵抗によって減速される。
【００１６】
以上の請求項１、請求項４に記載された発明とも、ごみ容器に収容されるごみが非円筒状のブロックであっても、または極く少量であっても、落下時に空気流は、確実に空気流入用の間隙や外筒下端の開口や断続的な接合部の間に形成された外筒と内筒との間隙から流入するため、従来のごみ容器では必要とした円板体を不要とすることができる。更に、ごみは密閉された内筒に収容されるので、ごみからの汚水がごみ容器から漏出することはない。
【００１７】
【実施例】
以下、本発明による高層ビルのごみ輸送装置用のごみ容器の実施例を図８乃至図１２と同部分には同一符号を付して示した図１乃至図７を参照して説明する。
【００１８】
図１は本発明の第１の実施例の高層ビルのごみ輸送装置用のごみ容器を示したものである。図１において、ごみ容器１６は、合成樹脂シートのような軟質性円筒状シート材製の外筒１７と、この外筒１７と同径または僅かに小径の合成樹脂シートのような軟質性円筒状シート材製の内筒１８とから構成されている。この外筒１７の口径は図８に示した垂直輸送管２の内径よりも僅かに小径となるように定められている。また、外筒１７は上端が開放され、その下端は一部１７ａが内筒１８の下端に接合され、下端の残部１７ｂが斜めに切断され二つの開口１９が形成されている。これらの開口１９は互いに対向する位置、すなわち外筒１７を円形に拡げた状態で１８０°離れた位置に存在する。内筒１８は上端が開放され、下端が閉止するように接合されている。この接合された内筒１８の下端には、上述のように外筒１７の下端の一部１７ａが接合されている。
【００１９】
これらの外筒１７及び外筒１８は次のようにして作られる。すなわち、図１において一枚の筒状の合成樹脂シート１７０と、この合成樹脂シート１７０と長さが同一で口径が同一かもしくは僅かに小径の一枚の筒状の合成樹脂シート１８０とが夫々用意される。これらの二枚の合成樹脂シート１７０、１８０の各々は上端及び下端が夫々開放されている。合成樹脂シート１７０の内部に合成樹脂シート１８０が挿入される。なお、この合成樹脂シート１８０は、図示のように両側部を折り畳んだ状態で合成樹脂シート１７０内に挿入される。この状態で、合成樹脂シート１７０の下端と合成樹脂シート１８０の下端が熔着され、次いで合成樹脂シート１７０の下端のうち、合成樹脂シート１８０の下端に熔着された部分１７０ａ以外の部分１７０ｂを三角形状に切り取る。これによって、合成樹脂シート１８０は下端が接合されて閉止され、合成樹脂シート１７０は、下端の一部１７０ａが合成樹脂シート１８０の下端に接合にされると共に、一対の開口１９が穿孔される。このようにして、合成樹脂シート１７０及び合成樹脂シート１８０から外筒１７及び内筒１８が作成される。
【００２０】
次に、第１の実施例の作用を説明する。
図２において、大きな非円筒ブロック状のごみ１３は内筒１８内に詰込まれる。この詰込みの後に、外筒１７の上端及び内筒１８の上端が一緒に結束され、この結束によって、内筒１８は完全に密閉される。なお、外筒１７の一対の開口１９は内筒１８に収容されたごみ１３によって下方に大きく開放する。このようにごみ１３を内筒１８に収容したごみ容器１６が、図８に示したごみ投入装置３から垂直輸送管２に投入される。投入されたごみ容器１６は、外筒１７及び内筒１８の上端が一緒に結束され、かつ外筒１７及び内筒１８の下端が互いに接合されているため、両上端及び両下端の相対的位置関係を変えることなく垂直輸送管２内を落下する。この落下中に、空気が矢印で示したように開口１９から外筒１７と内筒１８との間に流入し、この流入した空気は、斜線で示したように外筒１７を丁度落下傘のように外側に膨らませる。なお、一対の開口１９は対向する位置に形成されているため、外筒１７は偏ることなく、円筒状に全周囲が一様に膨張する。
【００２１】
この外筒１７の膨張によって、外筒１７と垂直輸送管２の内壁との間隙の面積が小さくなる。これによって、ごみ容器１６の落下の際に外筒１７と垂直輸送管２の内壁との間隙を下方から上方に流れる空気の絞り効果による抵抗、即ち圧力損失が発生し、この抵抗はごみ容器１６の重量に拮抗し、ごみ容器１６の落下速度を自由落下に比べて十分に減速する。従って、図８に示した空気排出装置６と圧力検出装置７との作用によって、ごみ容器１６は、その重量に関係なく常にほぼ一定の速度で垂直輸送管２内を落下する。
【００２２】
図３は少量のごみ１３を内筒１８内に収容したごみ容器１６が垂直輸送管２内を落下する様子を示したもので、図２の場合と同様に空気が矢印で示したように開口１９から外筒１７と内筒１８との間に流入して、斜線で示したように外筒１７を丁度落下傘のように外側に膨らませる。従って、少量のごみ１３を収容する場合にも、ごみ容器１６は落下速度が自由落下に比べて十分に減速される。ごみ１３を収容する内筒１８は、下端が接合されかつ上端が結束されることによって全体が密閉されているため、ごみ１３が多量の汚水を含有する場合にも、汚水が内筒１８から漏出することはない。
【００２３】
図４は、本発明の第２の実施例を示したものである。
ごみ容器１６は軟質性円筒状シート材製の外筒１７と、この外筒１７と同径または僅かに小径の軟質性円筒状シート材製の内筒１８とから構成されている。この外筒１７の口径は垂直輸送管２の内径よりも僅かに小径となるように定められている。内筒１８は上端が開放され、下端１８ａが溶着によって接合され閉止されている。
【００２４】
また、外筒１７は上端及び下端が共に開放されており、下端から僅かな距離Ｄだけ上方の位置において周方向に沿って断続的に内筒１８に溶着されている。このような断続的な溶着によって、外筒１７は、内筒１８の外周と接合される所定長さの接合部（熔着部）２０が、周方向に沿って一定間隔で形成される。すなわち、図４及び図５に示されたように外筒１７は、周方向に沿って接合部２０と非接合部、即ち間隙部２１とが交互に形成される。もちろん、これらの非接合部２１では、外筒１７と内筒１８との間には間隙が形成されている。
【００２５】
次に、この第２の実施例の作用を説明する。
図６において、大きな非円筒ブロック状のごみ１３が内筒１８内に詰込まれた後に、第１の実施例の場合と同様に外筒１７及び内筒１８の上端が一緒に結束され、この結束によって内筒１８は完全に密閉される。なお、外筒１７の間隙部２１は内筒１８に収容されたごみ１３によって大きく開放する。
【００２６】
このようにごみ１３を内筒１８に収容したごみ容器１６は、図８に示したごみ投入装置３から垂直輸送管２に投入される。投入されたごみ容器１６は、外筒１７及び内筒１８の上端が一緒に結束され、かつ外筒１７及び内筒１８の下部が断続的に接合されているため、両上端及び両下部の相対的位置関係を変えることなく垂直輸送管２内を落下する。この落下によって、空気が間隙部２１から外筒１７と内筒１８との間に流入し、斜線で示したように外筒１７を丁度落下傘のように外側に膨らませる。この時、間隙部２１は外筒１７の全周にわたってほぼ均一に分布しているので、外筒１７は偏ることなく円筒状に全周囲が一様に膨張する。更に、ごみ容器１６の落下の際には、外筒１７の下端部Ｄは捲れ上がるので、空気は外筒１７の下端部Ｄによって邪魔されることなく間隙部２１にスムーズに流入することができる。その他の作用は第１の実施例と同一である。
【００２７】
図７は、比較的少量のごみ１３を内筒１８に収容したごみ容器１６を示したものである。この場合も、空気は確実に間隙部２１から外筒１７と内筒１８との間に流入し、斜線で示したように外筒１７を落下傘のように外側に膨らませる。
【００２８】
以上の実施例では、外筒１７と内筒１８とは、上下の２箇所、即ち上端の結束部と下部の接合部において互いに結合されていた。しかしながら、外筒１７の上端と内筒１８の上端は、必ずしも一緒に結束する必要はなく、夫々別々に結束しても良い。
【００２９】
【発明の効果】
以上の説明から明らかなように本発明によれば、ごみ容器はごみを収容する密閉の内筒と、下部において内筒と部分的に接合された外筒とから構成されるため、垂直輸送管を落下中に空気が外筒と内筒との間の空間に流入し、外筒を外方に膨張させるので、外筒と垂直輸送管との間の間隙が小さくなり、その間の空気抵抗が増大し、ごみ容器の落下速度を減速させることができる。特に、本発明のごみ容器は、外筒の膨張が内筒に収容されるごみの形状やごみの量に無関係に行われるので、従来のごみ容器では必要とされた円板体を必要としない。更に、本発明のごみ容器にあっては、ごみは密閉された内筒に収容されるので、ごみの汚水がごみ容器から漏出することはない。

[Industrial application fields]
The present invention relates to a waste container for a high-rise building garbage transport device, and more particularly, a high-rise building waste that is placed in a vertical transport pipe of a high-rise building and configured to fall in the vertical transport pipe at a substantially constant drop speed. The present invention relates to a garbage container for a transportation device.
[0002]
[Prior art]
Various types of high-rise building garbage transport devices have been developed that transport garbage collected from each floor of a high-rise building to the ground.
[0003]
FIG. 8 shows a typical high-rise building garbage transport device described in, for example, Japanese Patent Laid-Open No. 5-32302. The high-rise building 1 is provided with a vertical transport pipe 2 penetrating each floor. The pipe 2 is provided with a garbage throwing device 3 on each floor. A bottom lid 4 that can be opened and closed is attached to the lower end of the vertical transport pipe 2, and the bottom lid 4 is opened and closed by an opening / closing cylinder 5. Above the bottom lid 4, an air discharge device 6 that discharges air from the vertical transport pipe 2 in an adjustable manner and a pressure detection device 7 that detects the pressure in the vertical transport pipe 2 are installed. The vertical transport pipe 2 communicates with a chute 8 below the bottom lid 4, and a storage tank 9 is connected to the lower end of the chute 8, and garbage is collected in the garbage collection vehicle 10 after being stored in the storage tank 9. Is included.
[0004]
As shown in FIG. 9, the waste is accommodated in a soft cylindrical waste container 11 such as a synthetic resin sheet (poly sheet), and is carried to the waste input device 3 by the garbage cart 12. It is put into the transport pipe 2. The outer diameter of the waste container 11 is determined to be slightly smaller than the inner diameter of the vertical transport pipe 2 when the waste is sufficiently accommodated. Therefore, the waste container 11 has dropped in the vertical transport pipe 2. Sometimes, a relatively large air resistance is generated in the gap between the waste container 11 and the vertical transport pipe 2, and the air container causes the garbage container 11 to fall at a predetermined speed.
[0005]
The air discharge device 6 and the pressure detection device 7 are for setting the falling speed of the garbage container 11 to be substantially constant regardless of the weight of the garbage container 11. When the charged waste container 11 is relatively light, when the pressure in the lower part of the vertical transport pipe 2 is not very high, the air discharge device 6 is based on the detection output of the pressure detection device 7 that detects the pressure. A relatively large amount of air below is discharged to accelerate the falling speed of the garbage container 11. On the other hand, when the pressure of the lower portion of the vertical transport pipe 2 is high because the charged waste container 11 is relatively heavy, the air discharge device 6 is located below the waste container 11 based on the detection output of the pressure detection device 7 that detects the pressure. A relatively small amount of air is discharged to reduce the falling speed of the waste container 11. Thus, the thrown-in waste container 11 always falls in the vertical transport pipe 2 at a substantially constant speed and softly lands on the bottom lid 4 regardless of its weight.
[0006]
As described above, the above-described high-rise building garbage transport apparatus has a case where the waste 13 is not larger than a certain size and is loaded in the waste container 11 in a substantially uniform amount as shown in FIG. The outer diameter of the waste container 11 is slightly smaller than the inner diameter of the vertical transport pipe 2. As a result, the gap between the waste container 11 and the vertical transport pipe 2 becomes a substantially constant small area, and the air resistance passing through this gap becomes relatively large. It can be dropped at an almost constant speed regardless of the speed.
[0007]
However, when the garbage stored in the garbage container 11 is a non-cylindrical block such as a rectangular parallelepiped such as a bundled newspaper, the garbage container 11 is not formed in a cylindrical shape and falls in the vertical transport pipe 2. At this time, the gap between the waste container 11 and the inner wall of the vertical transport pipe 2 becomes considerably large, and the resistance of the air passing through this gap does not become so great that it balances with the waste container 11. The garbage container 11 suddenly descends and crashes into the bottom lid 4 and ruptures, causing a problem that dust inside scatters around.
[0008]
Therefore, in order to solve such a problem, JP-A-4-303303 and JP-A-5-32302 disclose a waste container 11 having a plurality of air holes 14 as shown in FIG. It is disclosed. The garbage container 11 accommodates garbage 13 in a non-cylindrical block such as bundled newspaper, and when the vertical transport pipe 2 is dropped, the air enters the garbage container 11 from the air hole 14 as indicated by an arrow. The waste container 11 is inflated to the outside and is shaped like a parachute. As a result, the gap between the waste container 11 and the inner wall of the vertical transport pipe 2 becomes a substantially constant small area, air resistance that antagonizes the weight of the waste container 11 is generated, and the falling speed of the waste container 11 is reduced. Thus, even when the non-cylindrical waste 13 is accommodated, the garbage container 11 with the air holes 14 perforated falls in the vertical transport pipe at a predetermined low speed and softly lands on the bottom lid.
[0009]
Furthermore, in Japanese Patent Laid-Open No. 5-32302, when the amount of dust in the garbage container is very small, the garbage container 11 is disposed at the upper part of the garbage container 11 having the air holes 14 as shown in FIG. It is disclosed that a disc body 15 having a diameter slightly smaller than the inner diameter is inserted. Even when the amount of dust is very small, the dust container 11 can be surely expanded outward by the air flowing in from the air holes 14 by the insertion of the disc body 15.
[0010]
[Problems to be solved by the invention]
However, when the above-mentioned garbage container with a perforated air hole contains waste containing a large amount of moisture, for example, waste generated from a kitchen or the like, sewage leaks from the air hole, and the interior of the vertical transport pipe In addition to the problem of contamination, when the amount of waste to be accommodated is small, a cumbersome operation is required in which a disk body must be inserted.
[0011]
Therefore, an object of the present invention is to reliably control the falling speed of the waste container in the vertical transport pipe to a low speed even if the amount of waste is small or the shape of the waste is non-cylindrical. An object of the present invention is to provide a waste container for a waste transport device for a high-rise building which can accommodate waste containing a large amount of water without leakage of sewage.
[0012]
[Means for Solving the Problems]

In this configuration, the lower end of the outer cylinder has at least two openings that act as the air inflow gap, and the lower end of the outer cylinder excluding the opening and the lower end of the inner cylinder are: It is desirable that they are joined together.
Moreover, it is desirable that the opening is formed by obliquely cutting the remaining portion at the lower end of the outer cylinder.
[0013]

[0014]
[Action]
The operation of the invention described in claim 1 is as follows. Since the lower ends of the outer cylinder and the inner cylinder are joined to each other, they fall integrally in the vertical transport pipe without changing the relative positional relationship between the lower ends. At the time of the fall, air flows between the outer cylinder and the inner cylinder from the opening at the lower end of the outer cylinder. The air that has flowed inflates the outer cylinder into a cylindrical shape, thereby reducing the gap between the outer cylinder and the inner wall of the vertical transport pipe. Thereby, the garbage container is decelerated by the resistance of the air flowing through the gap between the outer cylinder and the inner wall of the vertical transport pipe.
[0015]
The effect | action of the invention described in Claim 4 is as follows. Since the lower part of the outer cylinder and the inner cylinder are intermittently joined to each other, they fall integrally in the vertical transport pipe without changing the relative positional relationship between the lower ends. At the time of the fall, air flows between the outer cylinder and the inner cylinder through a gap between the outer cylinder and the inner cylinder formed between the intermittent joint portions. The air that has flowed inflates the outer cylinder into a cylindrical shape, thereby reducing the gap between the outer cylinder and the inner wall of the vertical transport pipe. Thereby, the garbage container is decelerated by the resistance of the air flowing through the gap between the outer cylinder and the inner wall of the vertical transport pipe.
[0016]
Even in the inventions described in claims 1 and 4 described above, even if the garbage contained in the garbage container is a non-cylindrical block or a very small amount, the air flow is surely ensured when falling. Inflow from the gap for air inflow, the opening at the lower end of the outer cylinder, and the gap between the outer cylinder and the inner cylinder formed between the intermittent joints, eliminating the need for the disc body required for conventional waste containers It can be. Furthermore, since waste is accommodated in the sealed inner cylinder, sewage from the waste does not leak from the waste container.

【Example】
Hereinafter, an embodiment of a garbage container for a high-rise building garbage transporting apparatus according to the present invention will be described with reference to FIGS. 1 to 7 in which the same parts as those in FIGS.
[0018]
FIG. 1 shows a garbage container for a high-rise building garbage transport apparatus according to a first embodiment of the present invention. In FIG. 1, a garbage container 16 includes an outer cylinder 17 made of a soft cylindrical sheet material such as a synthetic resin sheet, and a soft cylindrical shape such as a synthetic resin sheet having the same diameter as or slightly smaller than the outer cylinder 17. The inner cylinder 18 is made of a sheet material. The diameter of the outer cylinder 17 is determined to be slightly smaller than the inner diameter of the vertical transport pipe 2 shown in FIG. Further, the upper end of the outer cylinder 17 is opened, a lower end part 17a is joined to the lower end of the inner cylinder 18, and the remaining part 17b at the lower end is cut obliquely to form two openings 19. These openings 19 exist at positions facing each other, that is, at a position 180 ° apart in a state where the outer cylinder 17 is expanded in a circular shape. The inner cylinder 18 is joined so that the upper end is opened and the lower end is closed. A part 17a of the lower end of the outer cylinder 17 is joined to the lower end of the joined inner cylinder 18 as described above.
[0019]
These outer cylinder 17 and outer cylinder 18 are produced as follows. That is, one cylindrical synthetic resin sheet 170 in FIG. 1 and one cylindrical synthetic resin sheet 180 having the same length and the same diameter as or slightly smaller in diameter than the synthetic resin sheet 170, respectively. Prepared. Each of these two synthetic resin sheets 170 and 180 is open at the top and bottom. A synthetic resin sheet 180 is inserted into the synthetic resin sheet 170. The synthetic resin sheet 180 is inserted into the synthetic resin sheet 170 with both sides folded as shown. In this state, the lower end of the synthetic resin sheet 170 and the lower end of the synthetic resin sheet 180 are welded, and then, among the lower ends of the synthetic resin sheet 170, portions 170b other than the portion 170a welded to the lower end of the synthetic resin sheet 180 are removed. Cut it into triangles. As a result, the lower end of the synthetic resin sheet 180 is bonded and closed, and the lower end 170a of the synthetic resin sheet 170 is bonded to the lower end of the synthetic resin sheet 180, and the pair of openings 19 are perforated. In this manner, the outer cylinder 17 and the inner cylinder 18 are created from the synthetic resin sheet 170 and the synthetic resin sheet 180.
[0020]
Next, the operation of the first embodiment will be described.
In FIG. 2, a large non-cylindrical block-like garbage 13 is packed in an inner cylinder 18. After this clogging, the upper end of the outer cylinder 17 and the upper end of the inner cylinder 18 are bound together, and the inner cylinder 18 is completely sealed by this binding. The pair of openings 19 of the outer cylinder 17 is greatly opened downward by the dust 13 accommodated in the inner cylinder 18. Thus, the waste container 16 containing the waste 13 in the inner cylinder 18 is put into the vertical transport pipe 2 from the waste throwing device 3 shown in FIG. Since the upper ends of the outer cylinder 17 and the inner cylinder 18 are bundled together and the lower ends of the outer cylinder 17 and the inner cylinder 18 are joined to each other, the relative positions of the upper and lower ends It falls in the vertical transport pipe 2 without changing the relationship. During this fall, air flows between the outer cylinder 17 and the inner cylinder 18 from the opening 19 as shown by the arrow, and this inflowed air makes the outer cylinder 17 just like a parachute as shown by the oblique lines. Inflate outward. In addition, since a pair of opening 19 is formed in the position which opposes, the outer periphery 17 expands uniformly in a cylindrical shape, without biasing.
[0021]
The expansion of the outer cylinder 17 reduces the area of the gap between the outer cylinder 17 and the inner wall of the vertical transport pipe 2. As a result, when the garbage container 16 is dropped, a resistance due to a throttling effect of the air flowing upward from the lower side through the gap between the outer cylinder 17 and the inner wall of the vertical transport pipe 2, that is, a pressure loss, is generated. The falling speed of the garbage container 16 is sufficiently decelerated compared to free fall. Therefore, due to the action of the air discharge device 6 and the pressure detection device 7 shown in FIG. 8, the garbage container 16 always falls in the vertical transport pipe 2 at a substantially constant speed regardless of its weight.
[0022]
FIG. 3 shows a state in which a waste container 16 containing a small amount of waste 13 in an inner cylinder 18 falls in the vertical transport pipe 2, and air is opened as indicated by arrows as in the case of FIG. It flows in from 19 between the outer cylinder 17 and the inner cylinder 18, and as shown by the oblique line, the outer cylinder 17 is expanded outward just like a parachute. Therefore, even when a small amount of garbage 13 is accommodated, the falling speed of the garbage container 16 is sufficiently reduced compared to free fall. The inner cylinder 18 that accommodates the garbage 13 is hermetically sealed by joining the lower ends and binding the upper ends. Therefore, even when the garbage 13 contains a large amount of sewage, the sewage leaks from the inner cylinder 18. Never do.
[0023]
FIG. 4 shows a second embodiment of the present invention.
The garbage container 16 includes an outer cylinder 17 made of a soft cylindrical sheet material, and an inner cylinder 18 made of a soft cylindrical sheet material having the same diameter as or slightly smaller than the outer cylinder 17. The diameter of the outer cylinder 17 is determined to be slightly smaller than the inner diameter of the vertical transport pipe 2. The upper end of the inner cylinder 18 is opened, and the lower end 18a is joined and closed by welding.
[0024]
The outer cylinder 17 is open at both the upper and lower ends, and is intermittently welded to the inner cylinder 18 along the circumferential direction at a position slightly above the lower end by a distance D. As a result of such intermittent welding, the outer cylinder 17 is formed with a predetermined length of joining portions (welding portions) 20 to be joined to the outer periphery of the inner cylinder 18 at regular intervals along the circumferential direction. That is, as shown in FIGS. 4 and 5, in the outer cylinder 17, the joined portions 20 and the non-joined portions, that is, the gap portions 21 are alternately formed along the circumferential direction. Of course, a gap is formed between the outer cylinder 17 and the inner cylinder 18 in these non-joining portions 21.
[0025]
Next, the operation of the second embodiment will be described.
In FIG. 6, after the large non-cylindrical block-shaped garbage 13 is packed in the inner cylinder 18, the upper ends of the outer cylinder 17 and the inner cylinder 18 are bound together in the same manner as in the first embodiment. The inner cylinder 18 is completely sealed by binding. The gap portion 21 of the outer cylinder 17 is largely opened by the dust 13 accommodated in the inner cylinder 18.
[0026]
Thus, the waste container 16 containing the waste 13 in the inner cylinder 18 is put into the vertical transport pipe 2 from the waste throwing device 3 shown in FIG. Since the upper ends of the outer cylinder 17 and the inner cylinder 18 are bundled together and the lower portions of the outer cylinder 17 and the inner cylinder 18 are intermittently joined to the waste container 16 that has been charged, It falls in the vertical transport pipe 2 without changing the target positional relationship. As a result of the fall, air flows into the space between the outer cylinder 17 and the inner cylinder 18 from the gap portion 21 and causes the outer cylinder 17 to expand outwardly just like a parachute, as indicated by hatching. At this time, since the gap 21 is distributed substantially uniformly over the entire circumference of the outer cylinder 17, the outer circumference of the outer cylinder 17 expands uniformly in a cylindrical shape without being biased. Further, when the garbage container 16 is dropped, the lower end D of the outer cylinder 17 rises, so that air can smoothly flow into the gap 21 without being obstructed by the lower end D of the outer cylinder 17. . Other operations are the same as those of the first embodiment.
[0027]
FIG. 7 shows a garbage container 16 in which a relatively small amount of garbage 13 is accommodated in an inner cylinder 18. Also in this case, the air surely flows into the space between the outer cylinder 17 and the inner cylinder 18 from the gap 21 and causes the outer cylinder 17 to expand outward like a parachute as indicated by the hatched lines.
[0028]
In the above embodiment, the outer cylinder 17 and the inner cylinder 18 are coupled to each other at two locations, ie, the upper and lower binding portions and the lower joint portion. However, the upper end of the outer cylinder 17 and the upper end of the inner cylinder 18 do not necessarily have to be bundled together, and may be bundled separately.
[0029]
【The invention's effect】
As is apparent from the above description, according to the present invention, the waste container is composed of a sealed inner cylinder that accommodates garbage, and an outer cylinder that is partially joined to the inner cylinder at the lower portion. Since air flows into the space between the outer cylinder and the inner cylinder while dropping, the outer cylinder expands outward, so the gap between the outer cylinder and the vertical transport pipe is reduced, and the air resistance between them is reduced. It increases and the fall speed of a garbage container can be decelerated. In particular, the waste container of the present invention does not require the disc body required in the conventional garbage container because the expansion of the outer cylinder is performed regardless of the shape of the garbage accommodated in the inner cylinder and the amount of garbage. . Furthermore, in the garbage container of the present invention, since the garbage is accommodated in the sealed inner cylinder, the waste water of the garbage does not leak from the garbage container.
