Description

本発明は、一般家庭や事業所等から排出されるゴミや廃プラスチック類等を収容したゴミ袋を破袋するために用いられる破袋機に関する。   The present invention relates to a bag-breaking machine used for breaking a garbage bag containing garbage discharged from a general household or business office, waste plastics, and the like.

一般家庭等から排出されるゴミはビニール袋詰めされた複数の小袋を大袋に内蔵した状態で収集され、分別工場にて大袋とともに内蔵する小袋も破袋してゴミを取り出し、資源ゴミ、可燃ゴミ、不燃ゴミに分別される。このとき、ゴミ袋を破袋するための破袋機として、破袋室内に複数の破袋刃を突設した破袋軸を配設し、破袋軸を回転することで破袋刃をゴミ袋に押し当てて引き裂くものが知られている。   Garbage discharged from ordinary households is collected in a state where multiple sachets packed in plastic bags are built in large bags, and the sachets built in together with the large bags are broken up at the sorting factory to take out the trash, and resources and combustible trash Sorted into non-combustible garbage. At this time, as a bag-breaking machine for breaking the garbage bag, a bag-breaking shaft provided with a plurality of bag-breaking blades is disposed in the bag-breaking chamber, and the bag-breaking blade is turned into garbage by rotating the bag-breaking shaft. What is known to tear against a bag.

前記破袋機のように破袋刃を突設した破袋軸を回転させながら破袋すると、引き裂かれた袋片が破袋刃や破袋軸に絡み付くことは避けられず、袋片がある程度絡みつくと破袋作業を一時中断し、破袋軸を逆転させて絡みついた袋片を少しでも取り除いたり、また手作業にて除去することが行われている。   If the bag breakage is carried out while rotating the bag breaking shaft with protruding bag breaking blades as in the bag breaking machine, it is inevitable that the torn bag pieces will get entangled with the bag breaking blade and the bag breaking shaft. When entangled, the bag breaking operation is temporarily interrupted, the bag breaking shaft is reversed and the tangled bag pieces are removed or removed manually.

そこで、破袋刃や破袋軸に強固に絡み付いた袋片の除去作業は厄介であるため、特許文献１では、一対の破袋軸に突設した破袋刃のそれぞれの刃先を他方の破袋軸に接近させて取り付け、双方の破袋軸を異なる回転数にて回転させて破袋を行いながら、この破袋中に破袋刃が他方の破袋軸に絡み付いた袋片を切り裂くようにし、絡み付きが多くなってくると装置を停止させ、破袋軸を逆転させて破袋軸に絡み付いた袋片を取り除きやすくした後に手作業で取り除くことで、除去作業を短時間で行えるようにしている。   Therefore, since the removal work of the bag piece firmly entangled with the bag breaking blade and the bag breaking shaft is troublesome, in Patent Document 1, each cutting edge of the bag breaking blade protruding from the pair of bag breaking shafts is connected to the other breaking edge. Attach it close to the bag shaft, rotate both of the bag breaking shafts at different rotation speeds to break the bag, and during this bag breaking, the bag breaking blade will tear the bag piece entangled with the other bag breaking shaft When the number of entanglements increases, the device is stopped, and the bag breaker shaft is reversed to facilitate removal of the bag pieces entangled with the bag breaker shaft. ing.

また、特許文献２では、回転する破袋刃に向けて空気噴射ノズルを配設し、該空気噴射ノズルから圧縮空気を噴射して破袋刃に絡み付いた袋片を吹き飛ばし、破袋中に破袋刃に袋片が絡み付かないようにしている。   Moreover, in patent document 2, an air injection nozzle is arrange | positioned toward the rotating bag breaking blade, a compressed air is injected from this air injection nozzle, the bag piece entangled with the bag breaking blade is blown away, and it breaks during bag breaking. The bag piece is prevented from being entangled with the bag blade.

また、特許文献３では、前記と同様に破袋中に破袋刃に袋片が絡み付かないようにするために、回転する破袋刃の両側面に回転板の外周部両側を接触させ、回転板を高速で回転させることで、破袋刃に絡み付く袋片を取り除くようにしている。
特開２００１−２９８３１号公報 実開平５−７４６４３号公報 特開平５−２７７３９３号公報 Moreover, in patent document 3, in order to prevent a bag piece from being entangled with the bag breaking blade during bag breaking as described above, both sides of the outer peripheral portion of the rotating plate are brought into contact with both side surfaces of the rotating bag breaking blade, By rotating the rotating plate at a high speed, the bag piece entangled with the bag breaking blade is removed.

しかしながら、前記従来の破袋機のうち、引き裂かれた袋片が破袋刃や破袋軸に絡み付くままにし、ある程度絡みつくと除去作業を行うものは、破袋作業をしばしば中断しなければならない欠点がある。また、破袋中に袋片が破袋刃に絡み付かないようにしたものでは、破袋刃に向けて圧縮空気を噴射する装置を要したり、破袋刃の両側面に接触して高速回転する回転板を要したり、装置が複雑となる欠点がある。   However, among the conventional bag-breaking machines, those in which the torn bag piece remains entangled with the bag-breaking blade and the bag-breaking shaft, and the removal operation is performed to some extent, the defect that the bag-breaking operation must be interrupted frequently There is. Also, if the bag piece does not get entangled with the bag breaking blade during bag breaking, a device that jets compressed air toward the bag breaking blade is required, or both sides of the bag breaking blade are in contact with the high speed. There are drawbacks in that a rotating plate is required and the apparatus is complicated.

本発明は上記の点に鑑み、簡単な構成で、破袋刃に絡み付く袋片を取り除きながら効率良く破袋することができる破袋機を提供することを課題とする。   In view of the above points, an object of the present invention is to provide a bag breaking machine that can break a bag efficiently with a simple configuration while removing a bag piece entangled with a bag breaking blade.

上記の課題を解決するために、本発明に係る請求項１記載の破袋機では、上部に被処理物であるゴミ袋の投入口を有し、下部に処理物の排出口を有する破袋室内に一対の破袋軸を平行に回転自在に配設し、該破袋軸の外周に複数の破袋刃を軸方向に所定間隔で突設して成る破袋機において、前記破袋刃は片側のみに袋体を引っ掛けて破く引っ掛け部を形成し、破袋軸の回転時に、一方側の破袋軸の破砕刃は引っ掛け部形成側を先行させて回転することで破袋を行い、他方側の破袋軸の破砕刃は引っ掛け部非形成側を先行させて回転することで破袋刃に絡み付く袋片の除去を行うように構成するとともに、前記破袋軸を周期的に正・逆回転させる駆動手段を備えたことを特徴としている。   In order to solve the above-mentioned problem, in the bag breaking machine according to claim 1 according to the present invention, a bag breaking bag having an input port for a waste bag as an object to be processed at an upper portion and a discharge port for a processed item at a lower portion. In the bag breaking machine, wherein a pair of bag breaking shafts are rotatably disposed in parallel in a room, and a plurality of bag breaking blades are projected on the outer periphery of the bag breaking shaft at predetermined intervals in the axial direction. Hooks the bag body only on one side to form a hook part, and when the bag breaking shaft rotates, the crushing blade on one side of the bag breaking shaft rotates with the hook part forming side in advance to break the bag, The crushing blade of the other side of the bag breaking shaft is configured to remove the bag pieces entangled with the bag breaking blade by rotating the hooking portion non-forming side in advance, and periodically changing the bag breaking shaft to It is characterized by having a drive means for reverse rotation.

また、請求項２記載の破袋機では、一対の破袋軸の両側の破袋室内壁に固定刃を隣接する破袋刃の間に位置するように突設したことを特徴としている。   Further, the bag breaking machine according to claim 2 is characterized in that a fixed blade is projected between adjacent bag breaking blades on the bag breaking chamber inner walls on both sides of the pair of bag breaking shafts.

また、請求項３記載の破袋機では、破袋刃は、刃先を他方の破袋軸に接近させるように突設させたことを特徴としている。   According to a third aspect of the present invention, the bag breaking blade is characterized in that the blade breaking blade protrudes so that the blade tip approaches the other bag breaking shaft.

また、請求項４記載の破袋機では、破袋刃は、刃先を破袋軸の軸方向に所定角度ずつずらしながら配置したことを特徴としている。   According to a fourth aspect of the present invention, the bag breaking blade is characterized in that the blade breaking blade is arranged while being shifted by a predetermined angle in the axial direction of the bag breaking shaft.

本発明に係る請求項１記載の破袋機によれば、破袋室内に複数の破袋刃を突設した一対の破袋軸を有した破袋機において、前記破袋刃は片側のみに袋体を引っ掛けて破く引っ掛け部を形成し、破袋軸の回転時に、一方側の破袋軸の破砕刃は引っ掛け部形成側を先行させて回転することで破袋を行い、他方側の破袋軸の破砕刃は引っ掛け部非形成側を先行させて回転することで破袋刃に絡み付く袋片の除去を行うように構成するとともに、前記破袋軸を周期的に正・逆回転させる駆動手段を備えたので、破砕機の破袋運転中に、破袋と、破袋刃に絡み付く袋片の除去とを並行して行うとともに、破袋刃に絡み付く袋片が何層にも強固に絡み付く前に破袋軸が逆回転して袋片の除去が行われるため、破袋刃に絡み付く袋片を極力少なくでき、除去作業のための運転中断も少なくなって破袋作業を効率良く行うことができる。   According to the bag breaking machine according to claim 1 of the present invention, in the bag breaking machine having a pair of bag breaking shafts in which a plurality of bag breaking blades project in the bag breaking chamber, the bag breaking blade is only on one side. A hook part is formed by hooking the bag body, and when the bag breaker shaft rotates, the crushing blade of the bag breaker shaft on one side rotates with the hook part forming side in front, and breaks the bag. The crushing blade of the bag shaft is configured to remove the bag pieces entangled with the bag breaking blade by rotating with the hook part non-formation side leading, and driving to rotate the bag breaking shaft periodically forward and backward Because it is equipped with means, during the bag breaking operation of the crusher, the bag breaking and the removal of the bag piece entangled with the bag breaking blade are performed in parallel, and the bag pieces entangled with the bag breaking blade are strengthened in layers. Since the bag breaking shaft rotates reversely before entanglement, the bag piece is removed, so the bag piece tangled on the bag breaking blade can be reduced and removed as much as possible. Breakage working operation interrupt even fewer for work can be efficiently performed.

また、請求項２記載の破袋機によれば、一対の破袋軸の両側の破袋室内壁に固定刃を隣接する破袋刃の間に位置するように突設したので、引っ掛け部形成側を先行させて回転する破袋刃で押されたゴミ袋が固定刃で捕らえられて引き裂かれ、破袋が効率良く行える。また、引っ掛け部非形成側を先行させて回転する破砕刃側においては、破砕刃に絡み付いた袋片が取り除かれやすい方向に回転しており、破砕刃が固定刃間を通過する際に破砕刃に絡み付いた袋片が固定刃で捕らえられ、袋片の除去をスムーズに行える。   Further, according to the bag breaking machine according to claim 2, since the fixed blade is protruded so as to be positioned between adjacent bag breaking blades on the wall of the bag breaking chamber on both sides of the pair of bag breaking shafts, the hook portion is formed. The garbage bag pushed by the bag breaking blade rotating with the side leading is caught and torn by the fixed blade, and the bag breaking can be performed efficiently. Also, on the crushing blade side that rotates with the hook part non-forming side leading, the bag piece entangled with the crushing blade rotates in a direction that is easily removed, and when the crushing blade passes between the fixed blades, The piece of the bag entangled with the bag is caught by the fixed blade, and the bag piece can be removed smoothly.

また、請求項３記載の破袋機によれば、破袋刃は、刃先を他方の破袋軸に接近させるように突設させたので、回転する破袋刃が他方の破袋刃や破袋軸に接近したときに、他方の破袋刃や破袋軸に絡み付いた袋片を破袋刃の引っ掛け部に引っ掛けて取り除くことができる。   Further, according to the bag breaking machine according to the third aspect, since the bag breaking blade is protruded so that the cutting edge is brought close to the other bag breaking shaft, the rotating bag breaking blade can be connected to the other bag breaking blade or the breaking bag. When approaching the bag shaft, the other bag breaking blade or the bag piece entangled with the bag breaking shaft can be hooked on the hook portion of the bag breaking blade and removed.

また、請求項４記載の破袋機によれば、破袋刃は、刃先を破袋軸の軸方向に所定角度ずつずらしながら配置したので、複数の破袋刃のそれぞれがゴミ袋に接触して引き裂くタイミングが少しずつずれるため、複数の破袋刃が同時にゴミ袋を引き裂く箇所がなくて負荷変動も少なくなり、所要動力が削減されるとともに、破袋が効率良く行える。   According to the bag breaking machine of claim 4, since the bag breaking blade is arranged while shifting the blade edge by a predetermined angle in the axial direction of the bag breaking shaft, each of the plurality of bag breaking blades contacts the garbage bag. Since the tearing timing is gradually shifted, there is no place where a plurality of bag breaking blades tear the garbage bag at the same time, the load fluctuation is reduced, the required power is reduced, and the bag breaking can be performed efficiently.

本発明に係る破袋機にあっては、上部に被処理物であるゴミ袋の投入口を有し、下部に処理物の排出口を有する破袋室内に一対の破袋軸を平行に回転自在に配設する。該破袋軸の外周には、片側のみに袋体を引っ掛けて破く引っ掛け部を形成した破袋刃を破袋軸方向に所定間隔で、かつ刃先を所定角度ずつずらしながら配置する。   In the bag-breaking machine according to the present invention, a pair of bag-breaking shafts are rotated in parallel in a bag-breaking chamber having a garbage bag input port at the upper part and a processing object discharge port at the lower part. Arrange freely. On the outer periphery of the bag-breaking shaft, a bag-breaking blade formed with a hook portion that hooks and tears the bag body only on one side is arranged at predetermined intervals in the bag-breaking shaft direction and with the blade edge being shifted by a predetermined angle.

この破袋刃は、双方の破袋軸の回転時に、一方側の破袋軸の破砕刃は引っ掛け部形成側を先行させて回転することで破袋を行い、他方側の破袋軸の破砕刃は引っ掛け部非形成側を先行させて回転することで破袋刃に絡み付つく袋片の除去を行うように取り付ける。また、双方の破袋軸を周期的、例えば数分間毎に正回転と逆回転を繰り返す駆動手段を備える。   This bag breaking blade breaks the bag by rotating the hook breaking shaft on the one side when the both sides of the bag breaking shaft rotate, and crushing the bag breaking shaft on the other side. The blade is attached so as to remove the bag piece entangled with the bag breaking blade by rotating with the hook portion non-forming side leading. In addition, there is provided drive means for periodically rotating both the bag breaking shafts, for example, every normal rotation and reverse rotation every few minutes.

また、前記一対の破袋軸の両側の破袋室内壁に固定刃を隣接する破袋刃の間に位置するように突設するとともに、破袋刃の刃先を他方の破袋軸に接近させて取り付ける。   In addition, a fixed blade is projected on the both sides of the pair of bag breaking shafts so as to be positioned between adjacent bag breaking blades, and the cutting edge of the bag breaking blade is brought close to the other bag breaking shaft. And attach.

そして、上記構成の破袋機にてゴミ袋を破袋するときには、破袋室の上位のホッパ内にゴミ袋をショベルローダー等で投入して貯め置き、一対の破袋軸を駆動手段によって周期的に正・逆回転を繰り返しながら、破袋室の投入口から落ち込んでくるゴミ袋を破袋刃の引っ掛け部にて引っ掛けて切り裂き、破袋した処理物を破袋室の排出口から排出していく。   When the bag breaker breaks the bag with the bag breaker configured as described above, the garbage bag is placed in the upper hopper of the bag breaker chamber with an excavator loader and stored, and the pair of bag breaker shafts are periodically driven by the driving means. While repeating forward and reverse rotation, the garbage bag falling from the opening of the bag breaking chamber is hooked at the hook of the bag breaking blade to tear it, and the processed bag is discharged from the discharge port of the bag breaking chamber. To go.

このとき、一対の破袋軸の一方側の破袋軸の破砕刃は引っ掛け部形成側を先行させて回転しているため、破袋刃の引っ掛け部がゴミ袋に引っ掛かるとゴミ袋を切り裂くこととなるが、基本的にはゴミ袋は破袋刃に押されて破袋室側壁に配置した固定刃に捕らえられて引き裂かれる。なお、破袋刃は破袋軸方向に所定角度ずつずらして配置しているため、複数の破袋刃のそれぞれがゴミ袋に接触して引き裂くタイミングが少しずつずれるため、複数の破袋刃が同時にゴミ袋を引き裂く箇所がなくて負荷変動も少ない。   At this time, since the crushing blade of the bag breaking shaft on one side of the pair of bag breaking shafts is rotated with the hook forming side leading, the garbage bag is torn when the hooking portion of the bag breaking blade is caught by the garbage bag. However, basically, the garbage bag is pushed by the bag breaking blade, is caught by the fixed blade arranged on the side wall of the bag breaking chamber, and is torn. Since the bag breaking blades are shifted by a predetermined angle in the bag breaking axis direction, the timing of tearing each of the plurality of bag breaking blades in contact with the garbage bag is shifted little by little. At the same time, there is no place to tear the garbage bag and there is little load fluctuation.

また、他方側の破袋軸の破砕刃は引っ掛け部非形成側を先行させて回転しているため、破袋は行われずに専ら破袋刃や破袋軸に絡み付いた袋片を外す方向に回転しており、袋片が破袋刃や破袋軸から外れやすくなるが、基本的には破袋刃や破袋軸に絡み付いた袋片は破袋室側壁に配置した固定刃に捕らえられたり、もう一方側の引っ掛け部形成側を先行させて回転する破砕刃に捕らえられたりして取り除かれる。   In addition, since the crushing blade of the other side of the bag breaking shaft is rotated with the hooked portion non-forming side leading, the bag breaking is not performed and the bag piece entangled with the bag breaking blade and the bag breaking shaft is exclusively removed. The bag piece is easy to come off from the bag breaking blade and the bag breaking shaft, but basically the bag piece entangled with the bag breaking blade and the bag breaking shaft is caught by the fixed blade placed on the side wall of the bag breaking chamber. Or by being caught by a crushing blade that rotates with the other hook-part forming side leading.

このように、一対の回転する破袋軸を有する破袋機において、一方側の破袋軸の破砕刃は引っ掛け部形成側を先行させて回転することで破袋を行う一方、他方側の破袋軸の破砕刃は引っ掛け部非形成側を先行させて回転することで破袋刃に絡み付く袋片の除去を行うようにすることにより、破袋と破袋刃に絡み付く袋片の除去を並行して行うことができ、破袋刃に絡み付く袋片を極力少なくでき、除去作業のための運転中断も少なくなって破袋作業を効率良く行うことができる。   In this way, in the bag breaking machine having a pair of rotating bag breaking shafts, the crushing blade of the one bag breaking shaft performs bag breaking by rotating the hook forming side first, while the other side breaking bag is broken. The crushing blade of the bag shaft is rotated with the hook part non-forming side leading, so that the bag piece entangled with the bag breaking blade is removed, so that the removal of the bag piece entangled with the bag breaking blade is performed in parallel. It is possible to reduce the number of pieces of the bag entangled with the bag breaking blade as much as possible, reduce the interruption of the operation for the removal operation, and perform the bag breaking operation efficiently.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図中の１はゴミ袋を破袋する破袋機であって、周囲を側壁により囲んだ破袋室２を有し、該破袋室２の上部に被処理物であるゴミ袋を投入する投入口３を、下部に処理物を排出する排出口４を有している。破袋室２には、軸体に所定径のドラム体を固着した破袋軸５、５´を所定間隔を隔てて一対平行に配置し、その両端部を破袋室２壁に貫通させて軸受６、６´にて回転自在に軸支している。   In the figure, reference numeral 1 denotes a bag breaking machine for breaking garbage bags, which has a bag breaking chamber 2 surrounded by a side wall, and a garbage bag as an object to be processed is put into the upper portion of the bag breaking chamber 2. The input port 3 has a discharge port 4 for discharging the processed material at the bottom. In the bag breaking chamber 2, a pair of bag breaking shafts 5, 5 ′ each having a drum body fixed to the shaft body are arranged in parallel at a predetermined interval, and both ends thereof are penetrated through the wall of the bag breaking chamber 2. It is rotatably supported by bearings 6 and 6 '.

前記破袋軸５、５´は、駆動手段である駆動用モータ７、７´に連結され、該駆動用モータ７、７´によって破袋軸５、５´の双方を同一方向に、かつ同一速度にて回転させるとともに、駆動用モータ７、７´は正回転また逆回転を周期的に、例えば数分毎に繰り返すように制御される。   The bag breaking shafts 5 and 5 'are connected to driving motors 7 and 7' as driving means, and both the bag breaking shafts 5 and 5 'are in the same direction and the same by the driving motors 7 and 7'. While rotating at a speed, the drive motors 7 and 7 'are controlled to repeat forward rotation or reverse rotation periodically, for example, every few minutes.

前記破袋軸５、５´の外周には、片側のみに袋体を引っ掛けて破く引っ掛け部８ａを形成した破袋刃８を破袋軸５、５´の外周周りに複数枚、更に軸方向に沿って所定間隔で突設している。破袋刃８は、実施例では、図１、図２に示すように、それぞれの破袋軸５、５´の外周周りに４枚を軸方向に７列配置している。なお、破袋刃５、５´の枚数は適宜決定すると良いが、破袋刃８の軸方向の配置間隔は、小袋の破袋をも考慮するとすればそれに見合った幅間隔とすると良い。   On the outer periphery of the bag-breaking shafts 5 and 5 ', a plurality of bag-breaking blades 8 having hook portions 8a for hooking and breaking the bag body only on one side are formed around the outer periphery of the bag-breaking shafts 5 and 5'. And projecting at predetermined intervals. In the embodiment, as shown in FIGS. 1 and 2, the four bag breaking blades 8 are arranged in four rows around the outer periphery of the respective bag breaking shafts 5 and 5 ′ in the axial direction. It should be noted that the number of the bag breaking blades 5 and 5 'may be determined as appropriate, but the arrangement interval in the axial direction of the bag breaking blade 8 is preferably a width interval corresponding to the bag breaking of the small bag.

破袋軸５、５´の回転方向は、図２の矢印に示すように、同一方向に正回転または逆回転させるため、正回転または逆回転のいずれに回転したときでも破袋できるように、左右の破袋軸５、５´の破袋刃８の引っ掛け部８ａを形成した面が逆になるように取り付けている。即ち、図２の矢印方向に破袋軸５、５´を回転すると、破袋軸５側の破袋刃８は引っ掛け部８ａ形成側を先行させて回転することで破袋を行う一方、他方側の破袋軸５´の破砕刃８は引っ掛け部非形成側８ｂを先行させて回転することで破袋刃８に絡み付く袋片を取り除く作用が働く。また、破袋軸５、５´を逆回転すると、前記とは反対に、破袋軸５側の破袋刃８で袋片の取り除き作用が働き、破袋軸５´側の破袋刃８にて破袋が行われる。また、回転する破袋軸５、５´のそれぞれの破袋刃８は同数とし、破袋軸５、５´間の中央部にてそれぞれの破袋刃８が交差するようにしておくと好ましい。   As shown by the arrows in FIG. 2, the rotation direction of the bag breaking shafts 5 and 5 ′ is rotated forward or backward in the same direction, so that the bag can be broken even when rotated forward or backward. The left and right bag-breaking shafts 5 and 5 ′ are attached so that the surfaces on which the hook portions 8a of the bag-breaking blades 8 are formed are reversed. That is, when the bag breaking shafts 5 and 5 'are rotated in the direction of the arrow in FIG. 2, the bag breaking blade 8 on the bag breaking shaft 5 side performs bag breaking by rotating with the hook portion 8a forming side first, while the other The crushing blade 8 of the side bag breaking shaft 5 ′ is rotated with the hooking portion non-forming side 8 b preceding to act to remove the bag piece entangled with the bag breaking blade 8. Further, when the bag breaking shafts 5 and 5 'are rotated in the reverse direction, the bag breaking blade 8 on the bag breaking shaft 5 side acts to remove the bag pieces and the bag breaking blade 8 on the bag breaking shaft 5' side. A bag breakage takes place. Further, it is preferable that the number of the bag breaking blades 8 of the rotating bag breaking shafts 5 and 5 ′ is the same, and the bag breaking blades 8 intersect each other at the center between the bag breaking shafts 5 and 5 ′. .

また、破袋室２の両側内壁には固定刃９を突設しており、該固定刃９は、図１のように、対峙する破袋刃８の間に位置するように、破袋軸５、５´の軸方向に沿って適宜間隔を隔てて複数配置している。この固定刃９は、破砕刃８が引っ掛け部８ａ形成側を先行させて回転するときに、破袋刃８に押されたゴミ袋を固定刃９にて捕らえて引き裂くものであり、また、破砕刃８が引っ掛け部非形成側８ｂを先行させて回転するときに、破袋刃８に絡み付いた袋片を固定刃９にて捕らえて袋片を取り除くものである。   Further, fixed blades 9 are provided on the inner walls on both sides of the bag-breaking chamber 2, and the fixed blades 9 are positioned between the bag-breaking blades 8 facing each other as shown in FIG. A plurality are arranged at appropriate intervals along the axial direction of 5, 5 ′. When the crushing blade 8 rotates with the hooking portion 8a forming side leading, the fixed blade 9 catches the torn garbage bag pushed by the bag breaking blade 8 with the fixed blade 9 and tears it. When the blade 8 rotates with the hook portion non-formation side 8b preceding, the bag piece entangled with the bag breaking blade 8 is caught by the fixed blade 9 to remove the bag piece.

また、破袋軸５、５´の軸方向に突設される破袋刃８は、図４に示すように、刃先を所定角度ずつ（図示例では１５度）ずらして配置している。これによって、破袋刃８の刃先のそれぞれがゴミ袋に接触して引き裂くタイミングが少しずつずれるため、複数の破袋刃８が同時にゴミ袋を引き裂く箇所がなくて負荷変動も少なくなって好ましい。   Further, as shown in FIG. 4, the bag breaking blade 8 protruding in the axial direction of the bag breaking shafts 5 and 5 ′ is arranged by shifting the cutting edge by a predetermined angle (15 degrees in the illustrated example). Accordingly, the timing at which each of the cutting edge of the bag breaking blade 8 comes into contact with the garbage bag and tears is shifted little by little. Therefore, there is no portion where the plurality of bag breaking blades 8 tear the garbage bag at the same time, and the load fluctuation is reduced.

次に、上記破袋機１によってゴミ袋を破砕するときは、先ず、破袋室２の上位のホッパ１０内にゴミ袋をショベルローダー等で投入して貯めながら、駆動モータ７、７´を駆動して一対の破袋軸５、５´を図２の矢印方向に回転させ、投入口３から破袋室２内に落ちてくるゴミ袋を破袋し、処理物を排出口４から下位の排出ホッパ１１に排出していく。そして、所定時間経過すると、駆動モータ７、７´を逆回転させ、破袋軸５、５´を図３に示す矢印方向に回転させてゴミ袋を破袋していく。この破袋軸５、５´の正・逆回転を周期的に繰り返して破袋作業を行っていく。   Next, when the garbage bag is crushed by the bag breaking machine 1, first, the drive motors 7 and 7 'are turned on while storing the garbage bag in the upper hopper 10 of the bag breaking chamber 2 with an excavator loader or the like. Driven to rotate the pair of bag breaking shafts 5, 5 ′ in the direction of the arrow in FIG. 2, break the garbage bags falling into the bag breaking chamber 2 from the inlet 3, and remove the processed material from the outlet 4. To the discharge hopper 11. When a predetermined time elapses, the drive motors 7 and 7 'are rotated in the reverse direction, and the bag breaking shafts 5 and 5' are rotated in the direction of the arrow shown in FIG. The bag breaking operation is performed by periodically repeating forward and reverse rotations of the bag breaking shafts 5 and 5 '.

図２においては、破袋軸５の破砕刃８は引っ掛け部８ａ形成側を先行させて回転しているため、破袋刃８の引っ掛け部８ａがゴミ袋に引っ掛かるとゴミ袋を切り裂くこととなるが、基本的には破袋刃８に押されたゴミ袋が固定刃９に捕らえられる領域Ａの箇所にて破袋が行われる。また、他方側の破袋軸５´の破砕刃８は引っ掛け部非形成側８ｂを先行させて回転しているため、破袋は行われずに専ら破袋刃８や破袋軸５´に絡み付いた袋片を取り除く作用が働いており、基本的には破袋刃８に絡み付いた袋片が固定刃９に捕らえられる領域Ｂの箇所にて取り除かれるとともに、双方の破袋軸５、５´の破袋刃８が交差する領域Ｃの箇所にて、破袋軸５´やその破袋刃８に絡み付いた袋片が破袋軸５の破袋刃８の引っ掛け部８ａに引っ掛けられて除去される。   In FIG. 2, since the crushing blade 8 of the bag breaking shaft 5 is rotated with the hook 8a forming side leading, the garbage bag is torn when the hook 8a of the bag breaking blade 8 is caught by the garbage bag. Basically, however, the bag breaking is performed in a region A where the garbage bag pushed by the bag breaking blade 8 is caught by the fixed blade 9. Further, since the crushing blade 8 of the other side bag breaking shaft 5 'is rotated with the hook portion non-forming side 8b leading, the bag breaking is not carried out and is entangled exclusively with the bag breaking blade 8 or the bag breaking shaft 5'. The bag piece entangled with the bag breaking blade 8 is removed at the region B where the fixed blade 9 catches the bag piece, and both the bag breaking shafts 5, 5 ′. In the region C where the bag breaking blade 8 intersects, the bag breaking shaft 5 ′ and the bag piece entangled with the bag breaking blade 8 are caught by the hook portion 8 a of the bag breaking blade 8 of the bag breaking shaft 5 and removed. Is done.

また、図３においては、破袋軸５、５´が逆回転しているため、破袋軸５´の破袋刃８によって領域Ｂの箇所で主として破袋が行われるとともに、領域Ａ及び領域Ｃの箇所にて他方側の破袋軸５やその破袋刃８に絡み付いた袋片の除去が行われる。   In FIG. 3, since the bag breaking shafts 5 and 5 ′ are rotating in the reverse direction, the bag breaking blade 8 of the bag breaking shaft 5 ′ performs bag breaking mainly in the region B, and the regions A and The bag piece entangled with the bag breaking shaft 5 on the other side or the bag breaking blade 8 is removed at the position C.

また、破袋刃８は、刃先を破袋軸５、５´の軸方向に所定角度ずつずらしながら配置すると、図４に示すように、破袋刃８の刃先がゴミ袋に接触して引き裂くタイミングが少しずつずれ、複数の破袋刃８が同時にゴミ袋を引き裂く箇所がなくて負荷変動も少なく、破袋も効率良く行われる。   In addition, when the bag breaking blade 8 is arranged while shifting the blade edge by a predetermined angle in the axial direction of the bag breaking shafts 5 and 5 ', the cutting edge of the bag breaking blade 8 comes into contact with the garbage bag and tears as shown in FIG. The timing is shifted little by little, and there is no place where the plurality of bag breaking blades 8 tear the garbage bag at the same time, so that the load fluctuation is small and the bag breaking is performed efficiently.

このように、上記破袋機１においては、破袋軸５、５´の一方側の破砕刃８は引っ掛け部８ａ形成側を先行させて回転することで破袋を行う一方、破袋軸５、５´の他方側の破砕刃８は引っ掛け部非形成側８ｂを先行させて回転することで破袋刃８に絡み付く袋片の除去を行うとともに、周期的に破袋軸５、５´を正・逆回転させるようにしたので、破袋と、破袋刃８や破袋軸５、５´に絡み付く袋片の除去を並行して行うことができ、破袋刃８や破袋軸５、５´に絡み付く袋片を極力少なくでき、除去作業のための運転中断も少なくなって破袋作業を効率良く行うことができる。   As described above, in the bag breaking machine 1, the crushing blade 8 on one side of the bag breaking shafts 5 and 5 'performs the bag breaking by rotating the hooking portion 8a in advance, while the bag breaking shaft 5 The crushing blade 8 on the other side of 5 ′ rotates with the hook portion non-forming side 8b in advance to remove the bag pieces entangled with the bag breaking blade 8, and periodically rotates the bag breaking shafts 5, 5 ′. Since the forward / reverse rotation is performed, the bag breaking and the removal of the bag pieces entangled with the bag breaking blade 8 and the bag breaking shaft 5, 5 ′ can be performed in parallel, and the bag breaking blade 8 and the bag breaking shaft 5. The bag piece entangled with 5 'can be reduced as much as possible, the operation interruption for the removal operation can be reduced, and the bag breaking operation can be performed efficiently.

なお、本実施例においては、破袋軸５、５´は同一回転数で、同一方向に正・逆回転させ、更に破袋軸５、５´のそれぞれの破袋刃８も同数としたが、何らこれに限定するものではなく、要は、破袋軸５、５´の一方側の破砕刃８は引っ掛け部８ａ形成側を先行させて回転することによる破袋と、破袋軸５、５´の他方側の破砕刃８は引っ掛け部非形成側８ｂを先行させて回転することによる絡み付く袋片の除去とを並行して行うようにすれば良く、本発明を逸脱しない範囲で種々変更できることは勿論である。   In this embodiment, the bag breaking shafts 5 and 5 'are rotated at the same rotational speed in the same direction, and the bag breaking blades 8 of the bag breaking shafts 5 and 5' have the same number. However, the present invention is not limited to this. In short, the crushing blade 8 on one side of the bag breaking shafts 5, 5 ′ is rotated with the hooking portion 8 a forming side in advance, and the bag breaking shaft 5, The crushing blade 8 on the other side of the 5 'may be removed in parallel with the removal of the entangled bag piece by rotating the hooking portion non-forming side 8b in advance, and various changes can be made without departing from the present invention. Of course you can.
