Description

本発明は、プラスチックフィルムや紙パック、発泡スチロール、アルミ箔などの包装材によって包装された各種の廃棄食品を包装材と中身の食品とに分離する廃棄包装食品の包装材分離装置に関する。 The present invention relates to a packaging material separating apparatus for waste packaged foods, which separates various types of discarded foods packaged by packaging materials such as plastic films, paper packs, polystyrene foam, and aluminum foil into packaging materials and contents foods.

スーパーマーケットやコンビニエンスストアの急速な普及に伴って、それらから大量の賞味正味期限切れ食品が廃棄されるようになった。食品は腐敗しやすく、腐敗すると悪臭を放つばかりでなく害虫を呼び寄せて環境汚染を起こしかねず、焼却しなければならない。有効活用するためにできるだけ短時間で包装材から分離して畜産用飼料などに利用する必要がある。従って、大量に廃棄包装食品を効率的に包装材から食品を分離できる装置の開発が待望されていた。従来の廃棄包装食品の包装材分離装置には、分離室内において包装材を引き裂く部材を十文字の横断面を有した回転分離翼の前縁外周部に設け、その回転で引き裂かれた包装材から分離した食品を下部のスクリーンから落下させ、分離した包装材を羽根が起こす空気流で整流板で案内して下流側の包装材排出口から排出するようにしたものがある(例えば、特許文献1参照)。 With the rapid spread of supermarkets and convenience stores, large quantities of net, net expired foods have been discarded from them. Food is easy to rot, and when it rots, it not only gives off a bad odor, but also attracts pests to cause environmental pollution and must be incinerated. In order to make effective use, it is necessary to separate it from the packaging material in as short a time as possible and use it for livestock feed. Therefore, there has been a long-awaited development of an apparatus capable of efficiently separating a large amount of waste packaged food from the packaging material. In a conventional packaging material separating apparatus for waste packaged food, a member for tearing the packaging material in the separation chamber is provided on the outer periphery of the leading edge of the rotary separating blade having a cross-shaped cross section, and separated from the packaging material torn by the rotation. There is a product in which the dropped food is dropped from the lower screen, and the separated packaging material is guided by a baffle plate with an air flow generated by the blades and discharged from the downstream packaging material discharge port (for example, see Patent Document 1). ).

以下、図6と図7とによって従来の廃棄食品の包装材分離装置を説明すると、ホッパ3から包装材で包装された廃棄食品が、ほぼ半円筒形の上部壁4bと複数の孔4c1を有した半円筒形の下部壁4cとを有した円筒形状の分離室4に投入され、モータ9で回転駆動される分離翼5によって包装材が引き裂かれて、食品が分離される。分離翼5は、中心に回転軸を、また分離室内壁に沿った所定の間隙をおいた略十字形の横断面をなすように翼部を有している。包装材を引き裂くL字型裂開突起5c1、5c2は、分離翼5のホッパ側端から突出している。分離室では所定の傾斜角度を有して配置された複数の整流板6によって所定の空気流が発生されて、包装材を排出口8から排出する。分離室食品は、分離室4の下部壁4cの孔4c1から食品蓄積部7に落下して蓄積される。
特開2001−62319号公報(要約、図1と図2)
Hereinafter, a conventional waste food packaging material separating apparatus will be described with reference to FIGS. 6 and 7. The waste food packaged with the packaging material from the hopper 3 has a substantially semi-cylindrical upper wall 4b and a plurality of holes 4c1. The semi-cylindrical separation wall 4 having the semi-cylindrical lower wall 4c is charged, and the packaging material is torn by the separation blade 5 that is rotationally driven by the motor 9, so that the food is separated. The separation blade 5 has a blade portion so as to form a substantially cross-shaped cross section with a rotation axis at the center and a predetermined gap along the separation chamber wall. L-shaped cleaving protrusions 5 c 1 and 5 c 2 that tear the packaging material protrude from the hopper side end of the separation blade 5. In the separation chamber, a predetermined air flow is generated by the plurality of rectifying plates 6 arranged with a predetermined inclination angle, and the packaging material is discharged from the discharge port 8. The food in the separation chamber falls and accumulates in the food accumulation section 7 from the hole 4c1 in the lower wall 4c of the separation chamber 4.
JP 2001-62319 A (Summary, FIGS. 1 and 2)

解決しようとする問題点は、廃棄食品の包装材を引き裂く手段が、回転分離翼5の前縁外周部に設けられたL字型裂開突起5c1、5c2で形成されているだけで、比較的丈夫な牛乳紙パックやポテトチップ紙筒などに対して十分に引き裂くことができず、特に後者の場合には中身との分離が不十分になることが多く、またそれら比較的丈夫な牛乳紙パックやポテトチップ紙筒の破砕が不十分で空気流で排出口8から排出するのが難しく、滞留しがちになる点である。また粘度の大きな稠密な食品が混入して来ると糊状に成りやすく、分離翼5のホッパ側に滞留して分離作業効率を大幅に低下するという問題もある。 The problem to be solved is that the means for tearing the packaging material of the waste food is formed only by the L-shaped cleaving protrusions 5c1 and 5c2 provided on the outer peripheral portion of the front edge of the rotary separation blade 5. It cannot be sufficiently torn against a strong milk paper pack or potato chip paper tube, and in particular, in the latter case, separation from the contents is often insufficient, and these relatively strong milk paper packs In addition, the potato chip paper tube is not sufficiently crushed and is difficult to be discharged from the discharge port 8 by an air flow, and tends to stay. In addition, when dense foods with high viscosity are mixed in, they tend to become paste-like and stay on the hopper side of the separation blade 5 to significantly reduce the separation work efficiency.

Between the plurality of protrusions arranged in a row and the plurality of protrusions arranged in the plurality of strips, extending from the supply-side shaft end toward the packaging material fragment outlet side, and on the inner surface of the cylindrical body The rotary spiral body is packaged from the supply shaft end on the circumferential surface of the rotary shaft and the rotary shaft, as another embodiment.

The configuration is made.

上記前置螺旋羽根と上記後置螺旋羽根とは、供給側の前縁部を斜め後方に傾斜させると共に該前縁部に三角形状の散らし板を回転方向に突出させて構成される。更に、上記螺旋羽根は、少なくとも外縁部に細長いゴムなどの柔軟材を交換可能に取り付けた構成とされる。 The front spiral blade and the rear spiral blade are configured such that a front edge portion on the supply side is inclined obliquely rearward and a triangular scattering plate is protruded in the rotation direction at the front edge portion. Further, the spiral blade is configured such that a flexible material such as a long and narrow rubber is exchangeably attached to at least the outer edge portion.

上記横長の円筒体は、包装材破片用出口を除いて全周に渡ってスクリーンを備えると共に、該円筒状スクリーンをその上部周りで間隔をおいて上部ケーシングで覆い、その下部を漏斗状の横断面をなす下部ケーシングで覆って分離室を構成することができる。また、上記分離室の円筒体は、その下部ケーシングの下部に分離食品を排出するスクリューコンベヤを備えることができる。上記分離室の横長の円筒体は、下流側端部において包装材破片用出口を上部のスクリーンの一部分で回転方向に向けて略接線方向に開口して形成すると共に該開口に連通した排出ダクトを上部ケーシングに設けることができる。別の実施例として、上記分離室の横長の円筒体は、ほぼ下半周に渡って半円筒状のスクリーンを備えると共に上部の半円筒状覆いを開閉可能に構成しており、上記半円筒状のスクリーンを漏斗状の横断面をなす下部ケーシングで覆っており、また該下部ケーシング下部に分離食品を排出するスクリューコンベヤを備えた構成を取ることができる。また、上記分離室の横長の円筒体は、下流側端部において包装材破片用出口を上部の半円筒状覆いの一部分で回転方向に向けて略接線方向に開口した排出ダクトによって構成される。 The horizontally long cylindrical body is provided with a screen over the entire circumference except for the outlet for the broken piece of packaging material, and the cylindrical screen is covered with an upper casing at an interval around the upper part, and the lower part is covered with a funnel-shaped crossing. The separation chamber can be formed by covering with a lower casing that forms a surface. The cylindrical body of the separation chamber may include a screw conveyor that discharges the separated food at the lower portion of the lower casing. The horizontally long cylindrical body of the separation chamber has an outlet for packaging material fragments formed in a part of the upper screen that is opened in a substantially tangential direction toward a rotational direction at a downstream end portion, and a discharge duct communicated with the opening. It can be provided in the upper casing. As another embodiment, the horizontally long cylindrical body of the separation chamber is provided with a semicylindrical screen substantially over the lower half circumference and is configured to open and close the upper semicylindrical cover. The screen may be covered with a lower casing having a funnel-shaped cross section, and a screw conveyor for discharging separated foods may be provided at the lower portion of the lower casing. In addition, the horizontally long cylindrical body of the separation chamber is constituted by a discharge duct having an outlet for a packaging material piece opened in a substantially tangential direction toward a rotational direction at a part of the upper semi-cylindrical cover at the downstream end.

本発明の効果として、投入部から投入された廃棄包装食品がたとえ比較的丈夫で重い牛乳紙パックやポテトチップ紙筒でも破砕手段によって破片に破砕されるために、包装材とその中身が完全に分離された状態で出口から分離室に排出することができる。従って、分離室内では回転駆動される回転螺旋体によって更に解されて中身の食品が効率的に包装材破片からほぼ完全に分離されることになる。回転螺旋体は、螺旋による機械的推力とブロワー作用の風力とによって破片を供給側から排出側の下流端側へ搬送するために、たとえ粘度の大きな稠密な飯物が混入して来ても、糊状に成る前に供給側に滞留させずに排出側の下流側へ散らして早くスクリーンを通して落下させることができ、また小さく破砕されて、食品が分離されて軽くなった包装材破片は分離室の包装材破片用出口から効率的に排出することができる。 As an effect of the present invention, since the waste packaged food introduced from the input unit is crushed into pieces by a crushing means even in a relatively strong and heavy milk paper pack or potato chip paper tube, the packaging material and its contents are completely In a separated state, it can be discharged from the outlet to the separation chamber. Therefore, the food in the contents is further completely separated from the packaging material fragments by being further unraveled by the rotating spiral body that is rotationally driven in the separation chamber. The rotating helix is used to transport debris from the supply side to the downstream end of the discharge side by mechanical thrust generated by the helix and the wind power of the blower. It can be quickly dispersed through the screen without stagnation on the supply side before it is formed, and can be quickly dropped through the screen. It can be efficiently discharged from the outlet for packaging material fragments.

破砕手段は、ほぼ水平に配置されたケーシングのほぼ全長に渡って上方に廃棄包装食品の投入部を備えることができ、その場合には、食品は包装されていても相対的に柔らかいので投入されるとすぐに破砕されるので破砕処理量を多くできる。上から下に噛み込む一対の互いに内側でオーバーラップした歯付き破砕螺旋体を設けると、殆どスリップ無しに包装食品を噛み込むことができると共に、骨などの硬いものが混じった食品があっても比較的小さい破片に破砕することができる。 The crushing means can be provided with an input portion for the waste packaged food over the substantially entire length of the casing arranged substantially horizontally, in which case the food is input because it is relatively soft even if it is packaged. As soon as it is crushed, the amount of crushing can be increased. By providing a pair of toothed crushing spirals that overlap each other from the top to the bottom, the packaged food can be chewed almost without slipping, and even if there are foods mixed with hard food such as bones Can be broken into small pieces.

回転螺旋体は、回転軸の周面上において少なくとも供給側において排出側の下流側の包装材破片用出口に向かって破片送りをかけるように螺旋状に複数条に間隔をおいて配列された複数の突起を有すると、間隔をおいた複数の突起によって破片を捕捉し、分離した食品を突起間隔を通すことによって解しと分離の能力を高め、同時に突起を螺旋状の複数条配列するとほぼ包装材破片だけを供給側から一方端側へ搬送する。複数条に配列された複数の突起の列の他に複数枚の螺旋羽根を供給側軸端から離れ場所から設けて、円筒体の内面に外縁を接するようにすると、更に機械的推力とブロワー作用の風力とによる包装材破片の出口側への搬送を促進すると共に食品のスクリーン通過排出も促進することができる。 The rotating spiral is a plurality of spirally arranged at intervals on a plurality of strips on the peripheral surface of the rotating shaft so as to feed the fragments toward the outlet for packaging material fragments on the downstream side on the discharge side at least on the supply side When it has protrusions, it captures debris by a plurality of spaced protrusions, improves the ability to unravel and separate the separated food by passing through the protrusion interval, and at the same time arranges the protrusions in a plurality of spiral strips, it is almost packaging material Only debris is transported from the supply side to one end. In addition to the rows of multiple protrusions arranged in multiple strips, a plurality of spiral blades are provided away from the supply-side shaft end so that the outer edge is in contact with the inner surface of the cylindrical body, further mechanical thrust and blower action It is possible to promote the conveyance of the packaging material fragments to the outlet side by the wind force of the food and also the discharge of food through the screen.

別の形態の回転螺旋体では、回転軸の周面上において供給側軸端から包装材破片用出口の手前まで延びた前置螺旋羽根と供給側軸端から離れ場所から包装材破片用出口側に向かって延びた後置螺旋羽根とは周囲方向において交互に配列されているために、供給側に破砕手段からの破片を受け入れるポケットを形成し、破砕手段から次々に供給されてくる破片をすぐに螺旋羽根の前部で跳ね飛ばさずに一旦ポケットに取り込んでから包装材破片用出口側に向かって移動しつつ分離することになり分離作業を前部に集中するのを防いで、回転軸螺旋体全体に分散して作業効率を高めることができる。逆に包装材破片用出口側では、前置螺旋羽根が出口手前で終結してポケットを形成して、次々と移動してくる包装材破片を一旦収容して終端まで延びている後置螺旋羽根によってポンプ作用で接線方向の出口に効率的に排出され、終端部で包装材破片が絡み合って排出不能になるのを防止できる。螺旋羽根の外縁は円筒体の内面に摺接していて、遠心力で円筒体の内面に付着した食品をその摺接によって更に強制的にスクリーンから外部に押し出すことができる。また供給側軸端部に取り付けられた少なくとも一対のブレードは、破砕手段から送られてくる破片を打撃して、部分的繋がっているような不完全な破片をバラバラにし、包装材と食品と分離を促進できるようにする。 In another form of the rotating spiral body, on the peripheral surface of the rotating shaft, the front spiral blade extending from the supply side shaft end to the front of the packaging material fragment outlet, and from the location away from the supply side shaft end to the packaging material fragment outlet side. Since the rear spiral blades extending in the direction are alternately arranged in the circumferential direction, a pocket for receiving debris from the crushing means is formed on the supply side, and the debris supplied one after another from the crushing means are immediately The entire rotating shaft spiral body prevents the concentration of separation work from being concentrated on the front part because it is separated from the front part of the spiral blade once it is taken into the pocket without jumping and moving toward the outlet side for the packaging material fragments. It is possible to increase the work efficiency by dispersing the system. On the other hand, on the outlet side for packaging material fragments, the front spiral blade terminates in front of the outlet to form a pocket, and once the packaging material fragments moving one after another are accommodated, the rear spiral blade extends to the end. Therefore, it can be efficiently discharged to the outlet in the tangential direction by the pump action, and it is possible to prevent the packaging material fragments from being entangled with each other at the end portion and becoming impossible to discharge. The outer edge of the spiral blade is in sliding contact with the inner surface of the cylindrical body, and the food attached to the inner surface of the cylindrical body by centrifugal force can be further forced out of the screen by the sliding contact. In addition, at least a pair of blades attached to the end of the supply-side shaft strikes the fragments sent from the crushing means, disassembles incomplete fragments that are partially connected, and separates the packaging material from the food. To promote.

前置螺旋羽根と後置螺旋羽根とは、供給側の前縁部を斜め後方に傾斜させることで破砕手段からの破片供給を容易にし、全体の分離作業の効率を高めることができる。更に前縁部に三角形状の散らし板を回転方向に突出させると、散らしばかりではなく三角形の先による破砕とそれぞれの螺旋羽根間への破片の取り込みを促進することができる。更に、上記螺旋羽根は、少なくとも外縁部に細長いゴムなどの柔軟材を交換可能に取り付けると、遠心力でスクリーンを通過した食品以外に円筒体内面に付着した少し大きめの食品破片に対して当たって発生する騒音を低減すると共に繰り返しスクリーンへの押し込みを行って通過させることができる。 The front spiral blade and the rear spiral blade can facilitate the supply of debris from the crushing means by tilting the front edge portion on the supply side obliquely rearward, and can increase the efficiency of the entire separation operation. Further, when a triangular scattering plate is projected in the rotation direction at the front edge, not only the scattering but also the crushing by the tip of the triangle and the taking-in of fragments between the spiral blades can be promoted. Furthermore, when the flexible blade such as a long and narrow rubber is attached to be exchangeable at least at the outer edge portion, the spiral blade hits against a slightly larger food piece adhering to the inner surface of the cylindrical body in addition to the food passing through the screen by centrifugal force. The generated noise can be reduced and the screen can be repeatedly pushed through the screen.

横長の円筒体は包装材破片用出口を除いて全周に渡ってスクリーンを備えると、分離された食品が螺旋羽根によって受ける遠心力によって全周方向のどこでもスクリーンを通過し、上部及び下部のケーシングによって受け止められ下部ケーシングに収集されることになり、包装材破片の出口側への移動が分離食品によって阻害されることが少なく、同時に包装材と食品との分離も促進される分離室を構成できる。上部ケーシングを開閉可能に構成することで、スクリーン目詰まり等の内部点検と掃除や修理などの保守を容易に行うことができる。 When the horizontally long cylindrical body is provided with a screen over the entire circumference except for the outlet for the broken piece of packaging material, the separated food passes through the screen everywhere in the circumferential direction due to the centrifugal force received by the spiral blade, and the upper and lower casings. Can be collected in the lower casing, so that the separation food is less likely to be hindered by the separated food and the separation of the packaging material and the food can be promoted at the same time. . By configuring the upper casing to be openable and closable, internal inspection such as screen clogging and maintenance such as cleaning and repair can be easily performed.

分離室の円筒体は、その下部ケーシングの下部に分離食品を排出するスクリューコンベヤを備えることができ、本装置の運転中でも分離食品をスクリューコンベヤによってほぼ定量的に安全に外部に排出し、安全に各種の容器に受けることができる。上記分離室の横長の円筒体は、下流側端部において包装材破片用出口を上部のスクリーンの一部分で回転方向に向けて略接線方向に開口して形成すると、分離包装材の破片をスムーズに搬出することができる。また該開口に連通した排出ダクトを上部ケーシングに設けることで、勢いよく飛び出してくる包装材破片を安全な方向にダクトによって導くことができる。 The cylinder of the separation chamber can be equipped with a screw conveyor that discharges the separated food at the lower part of the lower casing, and the separated food can be discharged to the outside almost quantitatively and safely by the screw conveyor even during operation of this device. Can be received in various containers. The horizontally long cylindrical body of the separation chamber is formed by forming a packaging material fragment outlet at a downstream end portion of the upper screen so as to open in a substantially tangential direction toward a rotational direction at a part of the upper screen. Can be carried out. Further, by providing a discharge duct communicating with the opening in the upper casing, it is possible to guide the packaging material fragments popping out vigorously by the duct in a safe direction.

別の形態として、分離室の横長の円筒体は、ほぼ下半周に渡って半円筒状のスクリーンを備えると共に上部の半円筒状覆いを開閉可能に構成し、上記半円筒状のスクリーンを漏斗状の横断面をなす下部ケーシングで覆うことで、比較的処理量の少ない小型の装置に適した簡単な構造を得ることができ、上部の半円筒状覆いを開くことでスクリーン内部も直接点検や掃除や修理などの保守を容易に行うことができる。また該下部ケーシングの下部に分離食品を排出するスクリューコンベヤを備えると、本装置の運転中でも分離食品をスクリューコンベヤによってほぼ定量的に外部に排出し、安全に各種の容器に受けることができる。また、分離室の横長の円筒体は、下流側端部において包装材破片用出口を上部の半円筒状覆いの一部分で回転方向に向けて略接線方向に開口した排出ダクトによって構成すると、勢いよく飛び出してくる包装材破片を安全な方向にダクトによって導くことができる。 As another form, the horizontally long cylindrical body of the separation chamber is provided with a semicylindrical screen substantially over the lower half circumference, and the upper semicylindrical cover can be opened and closed, and the semicylindrical screen is formed in a funnel shape. By covering with a lower casing that has a transverse cross section of the above, it is possible to obtain a simple structure suitable for small devices with a relatively small throughput, and by opening the upper semi-cylindrical cover, the inside of the screen is also directly inspected and cleaned Maintenance such as repair and repair can be performed easily. If a screw conveyor for discharging separated food is provided at the lower part of the lower casing, the separated food can be discharged almost quantitatively to the outside by the screw conveyor even during operation of the apparatus, and can be safely received in various containers. In addition, the horizontally long cylindrical body of the separation chamber is vigorous when it is configured by a discharge duct that is opened in a substantially tangential direction toward the rotation direction at a part of the upper semi-cylindrical cover at the downstream end. Popping packaging material fragments can be guided in a safe direction by ducts.
