Description

【０００１】
【発明の属する技術分野】
本発明は、家庭から排出されるペットボトルまたはペットボトルが混入した廃棄物を圧縮処理する装置に関するものである。
【０００２】
【従来の技術】
従来からペットボトルまたはペットボトルが混入した廃棄物をブロック状に圧縮し、次に、この圧縮したブロックの周囲に結束線を緊締して圧縮ブロックを形成処理するもの（例えば、特開平７−３１５６２７号）が知られており、さらに、この圧縮ブロックの周囲をポリプロピレン樹脂バンド（ＰＰバンド）のような結束線により緊締する梱包装置（例えば、実公昭５７−３０２４８号）も知られている。そして、この圧縮装置の構成はホッパから廃棄物を１つの圧縮室内に投入し、この圧縮室内が満杯になると大型の油圧シリンダを駆動し、この廃棄物を圧縮して減容する。この圧縮の油圧シリンダは、圧縮室内に投入される廃棄物の量に応じてこれを十分に圧縮減容可能な圧縮力が必要であり、そのためにはこの圧縮力に応じた口径とこの圧縮室の高さに応じたストロークを有する圧縮シリンダが必要であった。そして、このような圧縮減容の動作は、油圧シリンダを伸縮作動を数回繰り返し、例えばこのような圧縮のための伸縮動作を４〜７回くり返すことにより、所定の質量（比重）を有する大きさの廃棄物の圧縮ブロックを形成し、この圧縮ブロックを移送用シリンダにより圧縮室から押し出し、この押し出された廃棄物の圧縮ブロックはＰＰバンドによって結束梱包して処理するものである。そして、このような圧縮ブロックは結束線で緊締してあるため搬送および埋め立て地に埋め立て処理するのに好適であった。
【０００３】
【発明が解決しようとする課題】
しかし、前記した従来の廃棄物の圧縮処理装置では、圧縮室が１個装置してあるため、この圧縮室内で大量の廃棄物を所定の比重まで圧縮するには、圧縮油圧シリンダは大型のものが必要である。そのため、この大型の油圧シリンダに作動流体を送りシリンダを伸縮作動をさせるには、どうしても長時間を要し、例えば廃棄物の圧縮ブロックの大きさが約６５０×４５０×３５０ｍｍの寸法の体積のもので、単位時間に処理できる能力は、３００ｋｇ程度が通常である。圧縮油圧シリンダは３０ｔｆ〜４０ｔｆの大きな圧縮能力を必要とするため、油圧シリンダの内径が大きくなり、そのため油圧シリンダの伸縮速度が遅くなる。そこで、本発明の目的は廃棄物の圧縮処理時間を短縮して時間当り処理能力を向上させ、ペットボトルまたはこのボトルが混入している廃棄物でも容易かつ敏速に圧縮処理が可能で、また、処理装置の製造コストも従来の装置と殆ど変らない廃棄物の圧縮処理装置を提供することにある。
【０００４】
【課題を解決するための手段】
上記の問題点を解決するために、本発明に係る廃棄物処理装置の特徴は、圧縮室を第１次圧縮室とこの第１次圧縮室と連通している第２次圧縮室とから構成し、上記第１次圧縮室とこの第１次圧縮室と連通している第２次圧縮室と間には、扉が開閉自在に設けてあり、上記第１次圧縮室には第１次圧縮シリンダが、上記第２次圧縮室には第２次圧縮シリンダがそれぞれ設けてあり、上記第１次圧縮室は投入口を有しかつその第１次圧縮シリンダの伸縮方向において上記第２次圧縮室の第２次圧縮シリンダの伸縮方向よりも長く、大きな容積の内部空間を有するものであり、上記第１次圧縮シリンダの方が、上記第２次圧縮シリンダよりも小口径でかつ長いストロークを有するものであって、上記第２次圧縮室の下流側側部には、この第２次圧縮室と連通する梱包手段が隣接状態で設置され、上記第１次圧縮室内で圧縮された廃棄物の圧縮ブロックは、移送手段により上記第２次圧縮室内に移送されるものであり、上記第２次圧縮シリンダは、上記第１次圧縮シリンダが作動していない時に圧縮動作を行ない、上記第２次圧縮室内で圧縮された廃棄物の圧縮ブロックは、この第２次圧縮室内に移送される上記第１次圧縮室内で圧縮された廃棄物によって、この第２次圧縮室と連通する梱包手段内に押し出されるところにある。
【０００５】
本発明の他の特徴は、上記移送手段は、所定寸法ごとに断続的に進出作動して、上記第１次圧縮室内で圧縮された廃棄物の圧縮ブロックを、上記第２次圧縮室内に断続的に移送するところにある。
【０００６】
【発明の実施の形態】
本発明の実施の態様を図面を参照して説明すると、図１において、廃棄物の圧縮室は２つの第１次、第２次の圧縮室１、２を基台３の上に連設してあり、この第１次圧縮室１とこの第２次圧縮室２とは開口１５を介して連通している。そして、第１次圧縮室１には第１次圧縮油圧シリンダ１２が、第２次圧縮室２には第２次圧縮油圧シリンダ２１がそれぞれ設けてある。第１次圧縮室１内で圧縮され減容されてブロック化した廃棄物の圧縮ブロックは、移送手段の油圧シリンダ４によりこの第２次圧縮室に移送され、ここで、最終圧縮成形されるようになっている。第１次圧縮室１内の大きさは、第１次圧縮シリンダ１２の伸縮方向において、第２次圧縮室２の第２次圧縮シリンダ２１の伸縮方向よりも長く大きな内部容積の空間を有する。
【０００７】
そこで、第１次圧縮室１の構成を具体的に説明すると、この圧縮室の１側面の上部には投入口１１が設けてあり、この投入口は廃棄物を投入するためのホッパまたはコンベヤに向けて開口し、廃棄物が投入可能となっている。また、第１次圧縮室１の天井板上面の中央部には、第１次圧縮油圧シリンダ１２が立設してあり、このシリンダから伸縮するシリンダ（ラム）の下端には押圧板１３が連結してあり、そのため、この押圧板はこの圧縮室内を上下方向に摺動自在になっている。第１次圧縮室１に設けてある油圧シリンダ１２は、第２次圧縮室２に設けてある圧縮油圧シリンダ２１に比較して、小口径でこの第１次圧縮室１の長さに応じて長いストロークのシリンダを具備している。第１次圧縮室１の下部両側には、対向的に開口１４、１５が設けてあり、一方（左側）の開口１４内には、圧縮ブロックＢを第２次圧縮室２内に移送するための押出し板４１が位置し、他方の開口１５は廃棄物の圧縮ブロックＢを第２次圧縮室２に移送させるためのもので、第２次圧縮室２に向けて開口している。
【０００８】
基台３の上面において、第１次圧縮室１の下部の一側（左側）の近傍には、移送用の油圧シリンダ４が設置してあり、この油圧シリンダから伸縮するラムの先端には移送用の押出し板４１が連結してあり、この押出し板は後退した状態では、図示のように開口１４内に位置し、油圧シリンダ４の作動によりこの第１次圧縮室１の下部を左右方向に往復移動可能であり、その先端面は延伸して第２次圧縮室２内にまで進入可能である。また、開口１５の外側面には扉５が上下方向にスライド自在に設置してあり、この扉はシリンダ５１によって上下方向に移動され、そのため開口１５は開閉可能である。
【０００９】
そして、扉５が上昇し開口１５が開くと、第１次圧縮室１は第２次圧縮室２と連通する。第２次圧縮室２の天井板の上面には、圧縮油圧シリンダ２１が設置してあり、このシリンダのラムの下端には押圧板２２が連結してあり、このシリンダ２１が作動すると、押圧板２２は第２次圧縮室２内を上下方向に往復移動するものである。第１次圧縮室１に設けてある油圧シリンダ１２は、前記したように小口径で長いストロークのもので、換言すれば、第２次圧縮室２に設けてある圧縮シリンダ２１は、第１次圧縮シリンダ１２よりも大口径であり、かつこのシリンダ２１の伸縮方向においても第１次圧縮シリンダ１２よりも短いストロークのものである。
【００１０】
さらに、第２次圧縮室２の下流側側部には隣接状態で梱包手段６が設置してあり、この梱包手段の構成は上部にＰＰバンドを巻回してあるリール６１からこのＰＰバンドが引出され、ガイド体６２にこのＰＰバンドを給送可能になっているもので、このガイド体の構成は圧縮ブロックが貫通し外部に排出できる中空部を有し、さらに、ＰＰバンドが挿通自在のガイドが設けてあるもので、正面形状はロ字状になっている。この具体的な構成は、前記した従来例の実公昭５７−３０２４８号公報に詳細に説明してある。
【００１１】
次に、本発明による廃棄物の圧縮梱包操作について説明する。
【００１２】
先ず、ペットボトル、またはペットボトルが混入している廃棄物を、ホッパまたはコンベヤ等により投入口１１から第１次圧縮室１内に投入する。第１次圧縮室１内が廃棄物で満杯になると、投入を停止し第１次圧縮油圧シリンダ１２を作動させる。押圧板１３を圧縮室１内で上下方向に往復運動を１回させることによりこの廃棄物を圧縮しブロック化する。この後、再びペットボトル、またはペットボトルが混入している廃棄物を、ホッパまたはコンベヤ等により投入口１１から第１次圧縮室１内に投入する。第１次圧縮室１内が廃棄物で満杯になると、投入を停止し第１次圧縮油圧シリンダ１２を再度作動させる。押圧板１３を圧縮室１内で上下方向に往復運動を１回させることにより廃棄物を圧縮し質量の増加した圧縮ブロックが形成される。この動作を４〜５回繰り返すことにより所定の質量の圧縮ブロックが形成される。この動作が行われている間は、第１次圧縮室１の開口１５の扉５は閉じている。この油圧シリンダ１２は、第２次圧縮油圧シリンダ２１に比較して小口径であるため、このシリンダに作動流体を送ってこのシリンダのラムを伸縮させる動作は敏速に行わせることができる。その後、油圧シリンダ５１を作動させ扉５は開口１５を開く。その後、移送用の油圧シリンダ４を作動させ、その押出し板４１で、圧縮ブロックＢを開口１５から第２次圧縮室内へ移送する。その後、押出し板４１を開口１４の位置まで後退させ、扉５で圧縮室１の開口１５を閉じる。この後、ペットボトル、またはペットボトルが混入している廃棄物が、ホッパまたはコンベヤ等により投入口１１から第１次圧縮室１内に投入され、第１次圧縮室内での圧縮行程が再び開始される。廃棄物が、投入口１１から第１次圧縮室１内に投入されている間に、第２次圧縮室２では油圧シリンダ２１を作動させて、押出し板２２を往復運動させ圧縮ブロックを最終圧縮成形する。第２次圧縮室２での圧縮動作は、廃棄物が、投入口１１から第１次圧縮室１内に投入されている時間内に行うので、ブロックの圧縮回数は、廃棄物の投入回数と同じとなる。また、この間、他油圧のシリンダを駆動していないので動力源を有効に利用することになる。油圧シリンダ２１は、ストロークが短く圧縮能力がシリンダ１２よりも大きいので十分に圧縮ブロックを圧縮することができる。
【００１３】
第１次圧縮室１内で、油圧シリンダ１２の駆動により廃棄物の圧縮減容が終了すると扉５を開き、移送用の油圧シリンダ４のラムを所定寸法ごとに断続的に進出作動させ、それにより押出し板４１を第２次圧縮室２内に断続的に進出させる。この断続的な動作は梱包手段６におけるＰＰバンドの結束を確実かつ容易に行うためである。そして、第２次圧縮室２内には、先に圧縮された最初の圧縮ブロックが存在しているため、この圧縮ブロックは第２次圧縮室２内から、図面右方に押出され、梱包手段６内にまで断続的に送り出される。そこで、この圧縮ブロックは梱包手段６のＰＰバンドにより緊締梱包され、そのまま外部に排出され、適宜の搬送手段により搬出される。
【００１４】
押出し板４１は、最初の圧縮ブロックを梱包手段６に送り出した後、開口１４の位置にまで後退し、扉５を油圧シリンダ５１の作動により閉じる。
【００１５】
そこで、投入口１１から第１次圧縮室１内に次の廃棄物を投入し、油圧シリンダ１２を作動させ、前記と同様に廃棄物を圧縮し、第２次圧縮室２内に送り出され、先に圧縮された圧縮ブロックは梱包手段６の方に押出され、新しい圧縮ブロックは第２次圧縮室２内で所定比重と形状を有する最終形状のブロックに形成され、梱包手段６により所定の寸法間隔でＰＰバンドで梱包されるのである。以下、同一工程により廃棄物は圧縮され梱包される。
【００１６】
【実施例】
廃棄物の圧縮ブロックが約６５０×４５０×３５０ｍｍの体積で、ブロックの質量が約１５ｋｇ程度のものを形成する実施例を説明する。
【００１７】
第１次圧縮室１に設置する圧縮用の油圧シリンダ１２の圧縮能力は約１０ｔｆのものを使用し、第２次圧縮室２の圧縮用の油圧シリンダ２１は約３５ｔｆのものを使用した。第１次圧縮室１内に投入したペットボトルを油圧シリンダ１２の押圧板１３を５回伸縮させて圧縮した。この場合の油圧シリンダ１２は小口径であるため、敏速な往復駆動が可能である。続いて開口１５の扉５を開き、移送用の油圧シリンダ４を作動させて、圧縮ブロックＢを第２次圧縮室２内に移送した。そこで、第２次圧縮室２で油圧シリンダ２１を作動させて押圧板２２により圧縮ブロックＢを再度加圧し圧縮した。その後、梱包手段６によって圧縮プロックＢをＰＰバンドで緊締した。
【００１８】
従来装置では圧縮ブロックを最終圧縮処理成形するのに約３分を要していたが、本発明の装置では約２．５分で最終処理が実現できた。つまり１時間当り約３６０ｋｇの廃棄物圧縮処理が実現した。また、従来の圧縮装置では大型の油圧シリンダを１個使用したものであったため、油圧シリンダのみならず油圧ポンプなど周辺機器もそれに応じて大型のものを使用しなければならず、そのため装置全体の製造コストは高いものとならざるを得なかったが、本発明のこの実施例では油圧シリンダ１２、２１は、それぞれ従来装置に比較して小型のものの使用が可能となり、それに伴ない周辺機器も小能力のものが採用でき、そのため装置全体の製造コストは従来のものに比較して、やや低下させることができた。
【００１９】
【発明の効果】
本発明によると、第１次圧縮室と第２次圧縮室を有し、第１次圧縮室の圧縮シリンダは小口径であるため伸縮作動が敏速であり、従来と同じ長いストロークであるが従来よりも廃棄物を短い時間で圧縮でき第１次圧縮室の圧縮シリンダが作動していない時に、第２次圧縮室で短いストロークの圧縮シリンダを作動させ、短時間で最終圧縮成形を行うので油圧源を効率よく利用でき、全体的に廃棄物の圧縮に要する時間が短縮され、そのため作業効率が向上する。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for compressing a plastic bottle discharged from a household or a waste mixed with a plastic bottle.
[0002]
[Prior art]
Conventionally, a PET bottle or waste mixed with a PET bottle is compressed into a block shape, and then a binding block is tightened around the compressed block to form a compressed block (for example, JP-A-7-315627) In addition, there is also known a packaging device (for example, Japanese Utility Model Publication No. 57-30248) that tightens the periphery of the compression block with a binding wire such as a polypropylene resin band (PP band). In the configuration of the compression device, waste is put into one compression chamber from a hopper, and when the compression chamber is full, a large hydraulic cylinder is driven to compress and reduce the volume of the waste. The compression hydraulic cylinder requires a compression force that can sufficiently compress and reduce the amount of waste that is put into the compression chamber. For this purpose, the diameter and the compression chamber according to the compression force are required. A compression cylinder having a stroke corresponding to the height of the cylinder was required. Such compression / volume reduction operation has a predetermined mass (specific gravity) by repeating the expansion / contraction operation of the hydraulic cylinder several times, for example, by repeating the expansion / contraction operation for such compression 4-7 times. A compressed block of waste having a size is formed, the compressed block is pushed out of a compression chamber by a transfer cylinder, and the pushed compressed block of waste is bundled and processed by a PP band. And since such a compression block is fastened with a binding wire, it was suitable for carrying and landfill processing in a landfill.
[0003]
[Problems to be solved by the invention]
However, since the conventional waste compression treatment apparatus has one compression chamber, the compression hydraulic cylinder is large in order to compress a large amount of waste to a predetermined specific gravity in the compression chamber. is required. For this reason, it takes a long time to send the working fluid to the large hydraulic cylinder and cause the cylinder to expand and contract. For example, the waste compression block has a volume of about 650 × 450 × 350 mm. The capacity that can be processed per unit time is usually about 300 kg. Since the compression hydraulic cylinder requires a large compression capacity of 30 tf to 40 tf, the inner diameter of the hydraulic cylinder becomes large, and therefore the expansion / contraction speed of the hydraulic cylinder becomes slow. Therefore, the object of the present invention is to shorten the waste compression processing time to improve the processing capacity per hour, and can easily and quickly compress the plastic bottle or waste mixed with this bottle, An object of the present invention is to provide a waste compression treatment apparatus in which the manufacturing cost of the treatment apparatus is almost the same as that of the conventional apparatus.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the waste treatment apparatus according to the present invention is characterized in that a compression chamber is composed of a primary compression chamber and a secondary compression chamber communicating with the primary compression chamber. A door is freely opened and closed between the primary compression chamber and the secondary compression chamber communicating with the primary compression chamber. The primary compression chamber has a primary opening. A compression cylinder is provided in the secondary compression chamber, and a secondary compression cylinder is provided in each of the secondary compression chambers. The primary compression chamber has an inlet, and the secondary compression cylinder extends and contracts in the expansion / contraction direction of the primary compression cylinder. The compression chamber is longer than the expansion / contraction direction of the secondary compression cylinder and has a large internal space. The primary compression cylinder has a smaller diameter and a longer stroke than the secondary compression cylinder. It is those having the above the downstream side of the secondary compression chamber, the second primary pressure Packing means for communicating with the chamber is disposed in an adjacent state, above the compressed block of the compressed waste primary compression chamber, which is transferred to the secondary compression chamber by the transfer means, the second The secondary compression cylinder performs a compression operation when the primary compression cylinder is not operating, and the waste compression block compressed in the secondary compression chamber is transferred to the secondary compression chamber. The waste compressed in the primary compression chamber is pushed into the packing means communicating with the secondary compression chamber .
[0005]
According to another feature of the present invention, the transfer means intermittently advances for each predetermined size, and the compressed block of waste compressed in the primary compression chamber is intermittently inserted into the secondary compression chamber. Is in the process of being transported .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a waste compression chamber has two primary and secondary compression chambers 1, 2 connected to a base 3. The primary compression chamber 1 and the secondary compression chamber 2 communicate with each other through an opening 15. The primary compression chamber 1 is provided with a primary compression hydraulic cylinder 12, and the secondary compression chamber 2 is provided with a secondary compression hydraulic cylinder 21. The compressed block of waste compressed and reduced in the primary compression chamber 1 is transferred to the secondary compression chamber by the hydraulic cylinder 4 of the transfer means, where it is finally compressed and molded. It has become. The size of the primary compression chamber 1 is longer and larger in the expansion / contraction direction of the primary compression cylinder 12 than the expansion / contraction direction of the secondary compression cylinder 21 of the secondary compression chamber 2.
[0007]
Therefore, the configuration of the primary compression chamber 1 will be described in detail. A loading port 11 is provided at the upper part of one side surface of the compression chamber, and this loading port is used as a hopper or conveyor for loading waste. It opens toward and waste can be input. A primary compression hydraulic cylinder 12 is erected at the center of the upper surface of the ceiling plate of the primary compression chamber 1, and a pressing plate 13 is connected to the lower end of a cylinder (ram) that expands and contracts from the cylinder. For this reason, the pressing plate is slidable vertically in the compression chamber. The hydraulic cylinder 12 provided in the primary compression chamber 1 is smaller in diameter than the compression hydraulic cylinder 21 provided in the secondary compression chamber 2 and has a small diameter according to the length of the primary compression chamber 1. It has a long stroke cylinder. Openings 14 and 15 are provided oppositely on both sides of the lower portion of the primary compression chamber 1, and the compression block B is transferred into the secondary compression chamber 2 in one (left side) opening 14. The other opening 15 is for transferring the waste compression block B to the secondary compression chamber 2, and is open toward the secondary compression chamber 2.
[0008]
On the upper surface of the base 3, a transfer hydraulic cylinder 4 is installed in the vicinity of one side (left side) of the lower portion of the primary compression chamber 1. When the push-out plate 41 is connected, and the push-out plate is retracted, the push-out plate 41 is positioned in the opening 14 as shown in the figure. The tip end surface can be extended and can enter into the secondary compression chamber 2. Further, the door 5 is slidably installed in the vertical direction on the outer surface of the opening 15, and the door is moved in the vertical direction by the cylinder 51, so that the opening 15 can be opened and closed.
[0009]
When the door 5 rises and the opening 15 opens, the primary compression chamber 1 communicates with the secondary compression chamber 2. A compression hydraulic cylinder 21 is installed on the upper surface of the ceiling plate of the secondary compression chamber 2, and a pressing plate 22 is connected to the lower end of the ram of this cylinder. 22 reciprocates in the secondary compression chamber 2 in the vertical direction. As described above, the hydraulic cylinder 12 provided in the primary compression chamber 1 has a small diameter and a long stroke. In other words, the compression cylinder 21 provided in the secondary compression chamber 2 is the primary cylinder. It has a larger diameter than the compression cylinder 12 and a stroke shorter than that of the primary compression cylinder 12 in the expansion / contraction direction of the cylinder 21.
[0010]
Further, packing means 6 is installed adjacent to the downstream side portion of the secondary compression chamber 2, and the structure of this packing means is that the PP band is pulled out from the reel 61 around which the PP band is wound. The PP band can be fed to the guide body 62. The structure of the guide body has a hollow portion through which the compression block passes and can be discharged to the outside. Further, the guide can be inserted through the PP band. The front shape is a square shape. This specific configuration is described in detail in Japanese Utility Model Publication No. 57-30248, which is a conventional example.
[0011]
Next, the waste packing operation according to the present invention will be described.
[0012]
First, a PET bottle or waste mixed with a PET bottle is introduced into the primary compression chamber 1 from the introduction port 11 by a hopper or a conveyor. When the interior of the primary compression chamber 1 is filled with waste, the charging is stopped and the primary compression hydraulic cylinder 12 is operated. This waste is compressed and blocked by causing the pressing plate 13 to reciprocate once in the vertical direction in the compression chamber 1. Thereafter, the PET bottle or the waste mixed with the PET bottle is again introduced into the primary compression chamber 1 from the introduction port 11 by a hopper or a conveyor. When the inside of the primary compression chamber 1 is filled with waste, the charging is stopped and the primary compression hydraulic cylinder 12 is operated again. By causing the pressing plate 13 to reciprocate once in the vertical direction in the compression chamber 1, the waste is compressed to form a compressed block having an increased mass. By repeating this operation 4 to 5 times, a compression block having a predetermined mass is formed. While this operation is being performed, the door 5 of the opening 15 of the primary compression chamber 1 is closed. Since the hydraulic cylinder 12 has a small diameter as compared with the secondary compression hydraulic cylinder 21, the operation of sending a working fluid to the cylinder and expanding and contracting the ram of the cylinder can be performed quickly. Thereafter, the hydraulic cylinder 51 is operated and the door 5 opens the opening 15. Thereafter, the transfer hydraulic cylinder 4 is operated, and the compression block B is transferred from the opening 15 into the second compression chamber by the pusher plate 41. Thereafter, the pushing plate 41 is retracted to the position of the opening 14 and the door 15 closes the opening 15 of the compression chamber 1. Thereafter, the PET bottle or the waste mixed with the PET bottle is introduced into the primary compression chamber 1 from the input port 11 by a hopper or a conveyor, and the compression process in the primary compression chamber starts again. Is done. While the waste is being introduced into the primary compression chamber 1 from the inlet 11, the hydraulic cylinder 21 is operated in the secondary compression chamber 2 to reciprocate the extrusion plate 22 to finally compress the compression block. Mold. Since the compression operation in the secondary compression chamber 2 is performed within the time when the waste is charged into the primary compression chamber 1 from the charging port 11, the number of block compressions is equal to the number of wastes charged. It will be the same. Further, during this time, since the other hydraulic cylinders are not driven, the power source is effectively used. The hydraulic cylinder 21 has a short stroke and a compression capacity larger than that of the cylinder 12, so that the compression block can be sufficiently compressed.
[0013]
In the primary compression chamber 1, when the compression reduction of the waste is completed by driving the hydraulic cylinder 12, the door 5 is opened, and the ram of the transfer hydraulic cylinder 4 is intermittently advanced for each predetermined dimension. Thus, the extruded plate 41 is intermittently advanced into the second compression chamber 2. This intermittent operation is for reliably and easily binding the PP band in the packing means 6. And since the first compression block compressed previously exists in the secondary compression chamber 2, this compression block is extruded from the secondary compression chamber 2 to the right side of the drawing, and packing means 6 is intermittently sent out. Therefore, the compressed block is tightly packed by the PP band of the packing means 6, discharged as it is, and carried out by an appropriate conveying means.
[0014]
The push-out plate 41 sends the first compressed block to the packing means 6, then moves back to the position of the opening 14 and closes the door 5 by the operation of the hydraulic cylinder 51.
[0015]
Therefore, the next waste is thrown into the primary compression chamber 1 from the charging port 11, the hydraulic cylinder 12 is operated, the waste is compressed in the same manner as described above, and sent into the secondary compression chamber 2, The previously compressed block is extruded toward the packing means 6, and a new compressed block is formed into a final shaped block having a predetermined specific gravity and shape in the secondary compression chamber 2, and the packing means 6 has a predetermined dimension. Packed in PP bands at intervals. Thereafter, the waste is compressed and packed in the same process.
[0016]
【Example】
An embodiment will be described in which the waste compression block has a volume of about 650 × 450 × 350 mm and the mass of the block is about 15 kg.
[0017]
The compression capacity of the hydraulic cylinder 12 for compression installed in the primary compression chamber 1 is about 10 tf, and the compression hydraulic cylinder 21 of the secondary compression chamber 2 is about 35 tf. The plastic bottle put into the primary compression chamber 1 was compressed by expanding and contracting the pressing plate 13 of the hydraulic cylinder 12 five times. In this case, since the hydraulic cylinder 12 has a small diameter, it can be rapidly reciprocated. Subsequently, the door 5 of the opening 15 was opened, the transfer hydraulic cylinder 4 was operated, and the compression block B was transferred into the secondary compression chamber 2. Therefore, the hydraulic cylinder 21 was operated in the secondary compression chamber 2, and the compression block B was pressurized again and compressed by the pressing plate 22. Thereafter, the compression block B was fastened with the PP band by the packing means 6.
[0018]
In the conventional apparatus, it took about 3 minutes to form the compression block in the final compression process, but in the apparatus of the present invention, the final process could be realized in about 2.5 minutes. In other words, a waste compression process of about 360 kg per hour was realized. In addition, since the conventional compression apparatus uses one large hydraulic cylinder, not only the hydraulic cylinder but also peripheral devices such as a hydraulic pump must use large ones accordingly. The manufacturing cost has to be high, but in this embodiment of the present invention, the hydraulic cylinders 12 and 21 can be used smaller than the conventional devices, respectively, and the peripheral equipment is small accordingly. Capable ones can be used, so that the manufacturing cost of the entire device can be reduced slightly compared to the conventional one.
[0019]
【The invention's effect】
According to the present invention, it has a primary compression chamber and a secondary compression chamber, and the compression cylinder of the primary compression chamber has a small diameter, so that the expansion and contraction operation is quick, and the stroke is the same as the conventional one. Since the waste can be compressed in a shorter time than the compression cylinder of the primary compression chamber is not operating, the compression cylinder with a short stroke is operated in the secondary compression chamber, and the final compression molding is performed in a short time. The source can be used efficiently, and overall the time required to compress the waste is reduced, thus improving the work efficiency.
