Description

【0001】
【発明の属する技術分野】
本発明は、選別機本体の中心線を通る鉛直面内で振動するトラフ上に投入された被選別物を下流側に搬送しつつ円筒状物と非円筒状物とに選別する形状選別機に関するものである。
【0002】
【従来の技術】
従来、例えばガラスビン等の資源ごみを形状別に選別する形状選別機としては、上流側に投入口と下流側に円筒状物用の排出口および非円筒状物用の排出口とをそれぞれ備え、円筒状物用排出口側が下方に来るように幅方向に傾斜するトラフが設けられ、このトラフを長手方向に振動させて前記投入口からトラフ上に投入された被選別物を下流側に搬送しつつ円筒状物と非円筒状物とに選別するものが用いられている。
【0003】
前記トラフは長手方向両端にガイドを有して略長方形状とされており、その搬送中心線が振動方向に一致するように配置されている。また、前記円筒状物用排出口および非円筒状物用排出口の境界線は前記搬送中心線とされている。このような構成において、前記投入口から投入された被選別物(資源ごみ)のうち円筒状物はトラフの斜面を下り下側のガイドに沿って下流側へ搬送される。一方、非円筒状物(例えば、角ビンやカレット等)は、トラフの斜面を下ることなく振動方向に対して平行に移動して下流側へ搬送される。こうして前記円筒状物および非円筒状物は、それぞれの排出口へ搬送される。
【0004】
【発明が解決しようとする課題】
しかしながら、前述された従来構造の形状選別機では、前記非円筒状物が搬送中心線より円筒状物用排出口側に投入された場合、その非円筒状物は振動方向に対して平行に移動して円筒状物用排出口へ搬送されてしまうという問題点がある。また、非円筒状物の選別効率を向上させるため、円筒状物用排出口および非円筒状物用排出口の境界線を円筒状物用排出口側に設定すると、円筒状物が非円筒状物用排出口に搬送されてしまうという問題点がある。このように選別効率が安定せず、信頼性が低く選別精度が悪いという問題点がある。
【0005】
本発明は、このような問題点を解消するためになされたもので、簡易な構造で被選別物を円筒状物と非円筒状物とに効率よく、高い精度で選別することができる形状選別機を提供することを目的とするものである。
【0006】
【課題を解決するための手段および作用・効果】
前述された目的を達成するために、本発明による形状選別機は、上流側に投入口と下流側に円筒状物用排出口および非円筒状物用排出口とをそれぞれ有するトラフと、このトラフを前記円筒状物用排出口側を下向きにして幅方向に傾斜させて支持する選別機本体と、この選別機本体に付設されて前記トラフを選別機本体の中心線を通る鉛直面内で振動させる振動手段とからなり、前記トラフの振動によりそのトラフ上に投入された被選別物を下流側へ搬送しつつ円筒状物と非円筒状物とに選別する形状選別機において、
前記トラフの被選別物搬送面の中心線の下流側が選別機本体の中心線に対して円筒状物用排出口側に所定角度傾斜してなることを特徴とするものである。
【0007】
本発明においては、被選別物搬送面の中心線の下流側が選別機本体の中心線に対して円筒状物用排出口側に所定角度傾斜するように選別機本体に支持されるトラフを振動手段により選別機本体の中心線を通る鉛直面内で振動させて、そのトラフの搬送面上に投入された被選別物を下流側へ搬送する。それら被選別物のうちの円筒状物は、トラフの幅方向の傾斜を転がりつつ下流側へ移動し円筒状物用排出口へ搬送される。一方、前記被選別物のうちの非円筒状物は、指向性を有するためトラフの幅方向の傾斜を上るように振動方向すなわち選別機本体の中心線と平行に移動し、下流側の非円筒状物用排出口へ搬送される。
【0008】
本発明によれば、円筒状物がトラフの幅方向の傾斜を下りつつ下流側に搬送され、また非円筒状物がトラフの幅方向の傾斜を上りつつ選別機本体中心線と平行に下流側に搬送されるため、それぞれの搬送軌跡が大きく異なり、非常に高い精度および効率で選別および回収を行うことができるという効果を奏する。
【0009】
また、本発明においては、前端部が投入口に接続され、後端部が搬送中心線に対して円筒状物用排出口側に角度を有する被選別物案内用のガイドが設けられるのが好ましい。こうすることにより、被選別物の投入時に非円筒状物がトラフの円筒状物用排出口側に位置するのを防止でき、より確実に選別精度および効率を向上させることができる効果を奏する。
【0010】
【発明の実施の形態】
次に、本発明による形状選別機の具体的な実施の形態につき、図面を参照しつつ説明する。
【0011】
図1には、本発明の一実施例に係る形状選別機1の平面図が示されている。また、図2には図1のA矢視図(a)およびB矢視図(b)がそれぞれ示されている。
【0012】
本実施例の形状選別機1は、架台2上に垂直方向に防振バネ3が複数本(本実施例では4本)設置されてなる選別機本体4に、3辺にガーダ5を備える平面視略平行四辺形状のトラフ6が支持されて構成されている。
【0013】
前記トラフ6は、前記ガーダ5のない1辺が下流側となるように配置され、その下流側の1辺が円筒状物用排出口8および非円筒状物用排出口9とされている。なお、前記各排出口8,9の境界線Cは、下流側1辺の略中間位置に設定されている。一方、このトラフ6の上流側には被選別物の投入口10が設けられている。また、このトラフ6上には、前端が前記投入口10に接続され、後端が搬送中心線Lに対して円筒状物用排出口8側に角度を有する被選別物案内用のガイド11が設けられている。
【0014】
また、前記トラフ6は、円筒状物用排出口8側を下向きにして幅方向に所定角度αで傾斜するように、かつそのトラフ6上の搬送面の中心線Lの下流側が選別機本体4の中心線Lに対して円筒状物用排出口8側に所定角度βを有するようにして、前記選別機本体4に支持されている。なお、本実施例において、角度αは2°〜5°が好ましく、角度βは2°〜10°が好ましい。
【0015】
前記選別機本体4には、長手方向左右両側にそれぞれ1台ずつの振動モータ12a,12b(本発明における振動手段に相当する。)が設置され、これら振動モータ12a,12bを互いに反対方向に回転させて自動的に同期化させ、完全な直線振動を発生させるように構成されている。これら振動モータ12a,12bには、バランスウエイト13が配置されており、この振動モータ12a,12bの回転によりトラフ6が選別機本体4の中心線Lを通る鉛直面内で水平に対して角度γの方向(図2中矢印D)に直線振動するようにされている。また、これら振動モータ12a,12bの振動数はインバータ方式により任意に変更することができ、被選別物の性状によって調整することができるようにされている。
【0016】
このように構成される形状選別機1においては、被選別物が投入口10よりトラフ6上の搬送面に投入され、このトラフ6の振動により下流側に搬送される。このように下流側に搬送されるに伴って、前記被選別物は前記ガイド11に沿って徐々にトラフ6の幅に広がるようにされていく。
【0017】
これら被選別物のうちの円筒状物は幅方向の傾斜によりトラフ6上を下りつつ下流側に搬送され、またトラフ6上を転がり円筒状物用排出口8側のガーダ5aに接触したものはこのガーダ5aに沿って下流側に搬送され、円筒状物用排出口8から排出される。
【0018】
一方、カレット・角ビン等の非円筒状物は、指向性を有しているためトラフ6の幅方向の傾斜を上るように直線振動方向すなわち選別機本体4の中心線Lと平行に下流側へ搬送され、また直線振動方向に沿って下流側に移動して非円筒状物用排出口9側のガーダ5bに接触したものはこのガーダ5bに沿って下流側に搬送され、非円筒状物用排出口9へ排出される。このように前記円筒状物はガーダ5aの下流端付近で円筒状物用排出口8に、非円筒状物はガーダ5bの下流端付近で非円筒状物用排出口9にそれぞれ回収される。
【0019】
本実施例によれば、トラフ6が所定角度αおよびβで傾斜するように選別機本体4に支持され、被選別物のうちの円筒状物がトラフ6の幅方向の傾斜を下るように搬送され、非円筒状物が前記傾斜を上るように搬送されるため、円筒状物と非円筒状物との搬送軌跡が大きく異なりそれぞれの回収率が向上し、高い精度で選別することができるという効果を奏する。
【0020】
次に、本実施例の形状選別機1を用いて、被選別物(円筒状物50%,非円筒状物50%)の形状選別を行なった際の回収率および選別精度(純度)が表1に示されている。但し、前記角度αは3°,角度βは3.5°に設定されている。
【表1】

Figure 0003597071
【0021】
この表から、本実施例の前記形状選別機1を用いれば、簡易な構造で被選別物を円筒状物と非円筒状物とに効率よく、高い精度で選別できることが明らかである。
【0022】
図3に、本実施例の変形例に係る形状選別機1’の平面図が示されている。本変形例の形状選別機1’においては、選別機本体4に平面視略長方形状のトラフ6’が支持されて、このトラフ6’上には、搬送方向に配置される2本のガーダ5a’,5b’と投入口10側幅方向の一辺に配置されるガーダ5c’とにより搬送面6a’が区画形成されて構成されており、その他の点においては前記実施例と異なるところがない。なお、前記実施例と共通する部分には、図に同一符号を付すに留めてその詳細な説明を省略することとする。
【0023】
本変形例において、前記トラフ6’は前記実施例と同様に所定角度αで幅方向に傾斜されている。また、このトラフ6’上の搬送方向に配置されるガーダ5a’,5b’のうちの非円筒状物用排出口9側に配置されるガーダ5b’は、略一直線に選別機本体4の中心線Lに対して所定角度βを有するように配置されて、その上流側端部がガーダ5c’の非円筒状物用排出口9側端部に連結される。一方、円筒状物用排出口8側に配置されるガーダ5a’は、略中心部で屈曲するく字形状とされており、その中心部より下流側は選別機本体4の中心線Lに対して所定角度βを有するように配置されており、その中心部より上流側は前記角度βより十分大きい角度を有するように配置されている。このようにガーダ5a,’5b’ ,5c’により区画形成される搬送面6a’下流側の中心線L’は、選別機本体4の中心線Lに対して所定角度βを有するようにされている。
【0024】
このように構成される形状選別機1’においては、前記実施例と同様に被選別物が投入口10から搬送面6a’上に投入されて、振動モータ12a,12bの作動によるトラフ6’の振動によって、下流側へ搬送される。このように下流側に搬送されるに伴って、前記被選別物はガーダ5a’の中心部より上流側に沿って徐々に広がるようにされていく。それら被選別物のうちの円筒状物は、トラフ6’の幅方向の傾斜により搬送面6a’上を下りつつ下流側に搬送され、またガーダ5a’に接触したものはこのガーダ5a’に沿って下流側に搬送され、円筒状物用排出口8から排出される。一方、非円筒状物は、トラフ6’の幅方向の傾斜を上るように選別機本体4の中心線Lと平行に下流側へ搬送され、またガーダ5b’に接触したものはこのガーダ5b’に沿って下流側に搬送され、非円筒状物用排出口9へ排出される。こうして搬送面6a’上に投入された被選別物が、非円筒状物と円筒状物とにそれぞれ選別される。
【0025】
本変形例によれば、ガーダ5a’,5b’,5c’により搬送面6a’が区画形成されるため、トラフ6’の形状に関わらず、前記実施例と同等の効果を得ることができる。また、従来の形状選別機のトラフに前記ガーダ5a’,5b’,5c’を設置することにより、形状選別機の製作コストを著しく低減させることができる。
【0026】
本変形例によれば、ガーダ5a’をく字形状として、前記実施例のガイド11の役割を兼ね備えるように構成されているが、これに限らず、前記ガーダ5a’を略直線状として前記ガイド11を投入口10側に装着するように構成してもよい。
【0027】
本実施例および変形例において、トラフ6,6’およびガーダ5a’,5b’,5c’の配設角度αは、被選別物の性状により防振バネ3の高さを変えるようにして任意に設定することができる。また、本実施例および変形例において、前記振動モータ12a,12bはインバータ方式が採られているが、これに限るものではない。また、前記振動モータ12a,12bの振動力は、前記バランスウエイト13の調整により差をつけることができ、これにより選別効率の向上を図ることができる。
【0028】
また、本実施例および変形例においては、トラフ6,6’が平面視平行四辺形状もしくは長方形状とされているが、これに限られるものではなく、例えば下流側が幅広の台形状であってもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shape sorter that sorts a cylindrical object and a non-cylindrical object while transporting an object to be sorted placed on a trough vibrating in a vertical plane passing through a center line of a separator body to a downstream side. Things.
[0002]
[Prior art]
Conventionally, for example, as a shape sorter that sorts resource refuse such as glass bottles by shape, an input port on the upstream side and a discharge port for a cylindrical object and a discharge port for a non-cylindrical object on the downstream side are provided, respectively. A trough inclined in the width direction is provided such that the discharge port side for the object comes downward, and the trough is vibrated in the longitudinal direction to convey the sorted material input onto the trough from the input port to the downstream side. What sorts into a cylindrical thing and a non-cylindrical thing is used.
[0003]
The trough is formed in a substantially rectangular shape having guides at both ends in the longitudinal direction, and is arranged such that a conveyance center line thereof coincides with the vibration direction. The boundary between the discharge port for the cylindrical object and the discharge port for the non-cylindrical object is the conveyance center line. In such a configuration, among the sorted objects (recyclable waste) input from the input port, the cylindrical object is transported down the slope of the trough to the downstream side along the lower guide. On the other hand, a non-cylindrical object (for example, a square bin or a cullet) moves parallel to the vibration direction without descending the slope of the trough and is transported downstream. Thus, the cylindrical and non-cylindrical objects are conveyed to their respective outlets.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional shape sorter, when the non-cylindrical object is introduced into the cylindrical object discharge port side from the transport center line, the non-cylindrical object moves parallel to the vibration direction. Therefore, there is a problem that the sheet is conveyed to the discharge port for cylindrical objects. In addition, in order to improve the sorting efficiency of non-cylindrical objects, if the boundary between the discharge port for cylindrical objects and the discharge port for non-cylindrical objects is set to the discharge port side for cylindrical objects, the cylindrical objects will be non-cylindrical. There is a problem that it is conveyed to the goods discharge port. Thus, there is a problem that the sorting efficiency is not stable, the reliability is low, and the sorting accuracy is poor.
[0005]
The present invention has been made in order to solve such a problem, and has a simple structure to efficiently sort a selected object into a cylindrical object and a non-cylindrical object with high accuracy. The purpose is to provide a machine.
[0006]
[Means for Solving the Problems and Functions / Effects]
In order to achieve the above-mentioned object, a shape sorter according to the present invention includes a trough having an inlet on an upstream side and a discharge port for a cylindrical article and a discharge port for a non-cylindrical article on a downstream side, respectively. And a sorter body for supporting the cylindrical object with the discharge port side facing downward and inclined in the width direction, and the trough attached to the sorter body and vibrating in a vertical plane passing through the center line of the sorter body. In the shape sorter, which comprises a vibrating means for causing the trough to vibrate and sort the non-cylindrical material into a cylindrical material and a non-cylindrical material while conveying the material to be sorted put on the trough to the downstream side,
A downstream side of a center line of the transporting surface of the object to be sorted of the trough is inclined at a predetermined angle toward a cylindrical object discharge port with respect to a center line of the sorting machine main body.
[0007]
In the present invention, the trough supported by the sorting machine main body is vibrated by a vibrating means such that the downstream side of the center line of the sorting object conveying surface is inclined at a predetermined angle toward the cylindrical object discharge port side with respect to the center line of the sorting machine main body. Vibrates in a vertical plane passing through the center line of the main body of the sorting machine, and conveys the sorting object put on the conveying surface of the trough to the downstream side. The cylindrical object among the sorted objects moves downstream while rolling on the inclination in the width direction of the trough, and is conveyed to the cylindrical object discharge port. On the other hand, the non-cylindrical object among the objects to be sorted moves in the vibration direction, that is, in parallel with the center line of the main body of the sorter, so as to ascend in the width direction of the trough because it has directivity. It is conveyed to the discharge port for articles.
[0008]
According to the present invention, the cylindrical object is conveyed to the downstream side while descending the inclination in the width direction of the trough, and the non-cylindrical object is moved in the downstream direction parallel to the center line of the sorting machine main body while ascending the inclination in the width direction of the trough. , The transport trajectories are greatly different from each other, so that the sorting and collection can be performed with extremely high accuracy and efficiency.
[0009]
Further, in the present invention, it is preferable that a guide for sorting objects having a front end connected to the input port and a rear end having an angle on the side of the cylindrical object discharge port with respect to the transport center line is provided. . By doing so, it is possible to prevent the non-cylindrical object from being located on the cylindrical object discharge port side of the trough when the object to be sorted is charged, and it is possible to more reliably improve the sorting accuracy and efficiency.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, specific embodiments of the shape sorter according to the present invention will be described with reference to the drawings.
[0011]
