Description

本発明は、大きさや材質が異なる種々の廃棄物を自動選別する装置に関する。   The present invention relates to an apparatus for automatically sorting various wastes having different sizes and materials.

建設現場などからでる産業廃棄物は、木くず、瓦礫、ビニールシート等の大きさや材質の異なるものが混在しており、自動で選別するのは難しい。少なくも大きさや比重で選別すると、以後の細かな選別が容易である。
また、砂浜における流木などの廃棄物と砂を自動で選別する装置はなかった。
そこで、本発明者の発明（特許文献１）になる装置を使用して廃棄物の選別をしてみたが、木くずや石だけでなく種々の材質のものが混合しているので、うまく選別できなかった。
特許第３５２６２９９号公報 Industrial waste from construction sites and the like are mixed with different sizes and materials, such as wood chips, rubble, and vinyl sheets, and are difficult to sort out automatically. If it sorts at least by size and specific gravity, the subsequent fine sorting is easy.
In addition, there was no device for automatically sorting waste such as driftwood on the sandy beach and sand.
Therefore, we tried to sort out waste using the device of the inventor's invention (Patent Document 1), but not only wood chips and stones but also various materials are mixed, so we can sort well. There wasn't.
Japanese Patent No. 3526299

本発明は上記欠点を解消して、廃棄物の選別を自動で行う装置を提供することを目的とする。   An object of the present invention is to provide an apparatus that automatically eliminates the above-described drawbacks and sorts waste.

上記目的を達成するために本発明は、
廃棄物を移送するベルトコンベアのベルトの中央部を両端部分より下方に突出させて断面半円形状にすると共に、
このベルトコンベアの上に、所定間隔離間して廃棄物選別用ロールを取付け、この廃棄物選別用ロールの回転軸を、ベルトの進行方向と平行に配置し
当該廃棄物選別用ロールに、複数の弾性部材の基端部を取付け、
また、当該弾性部材の先端部に廃棄物選別用杆を、その先端とベルトコンベアのベルトとの間隙がベルトコンベアの上流側ほど広くなるよう取付け、
さらに、ベルトコンベアの廃棄物排出側端部を凸曲面にすることを特徴とする。 In order to achieve the above object, the present invention provides:
The central part of the belt of the belt conveyor for transferring waste projects downward from both end parts to make it a semicircular cross section,
A waste sorting roll is mounted on the belt conveyor at a predetermined interval, and the rotation axis of the waste sorting roll is arranged in parallel with the traveling direction of the belt. Attach the base end of the elastic member,
In addition, a waste sorting basket is attached to the tip of the elastic member so that the gap between the tip and the belt of the belt conveyor becomes wider toward the upstream side of the belt conveyor,
Furthermore, the waste discharge side end of the belt conveyor is formed as a convex curved surface.

廃棄物選別用杆の先端とベルトコンベアのベルトとの間隙より径の小さな廃棄物は、この間隙をすり抜けて、ベルトコンベア外に出ることはない。一方、廃棄物選別用杆の先端とベルトコンベアのベルトとの間隙より径の大きな廃棄物は、この間隙をすり抜けられず、廃棄物選別用杆に接触する。
この接触した廃棄物は、所定の重量より重いと、弾性部材が折曲して、ベルト状に落下しベルトコンベア外に出ることはない。廃棄物の重量が所定以下のものに限り、廃棄物選別用杆によりベルトコンベア外に掃出される。 Waste having a diameter smaller than the gap between the tip of the waste sorting basket and the belt of the belt conveyor does not pass through the gap and come out of the belt conveyor. On the other hand, waste having a diameter larger than the gap between the tip of the waste sorting basket and the belt of the belt conveyor does not pass through the gap and contacts the waste sorting basket.
When the contacted waste is heavier than a predetermined weight, the elastic member bends, falls into a belt shape, and does not come out of the belt conveyor. As long as the weight of the waste is less than or equal to the predetermined weight, it is swept out of the belt conveyor by the waste sorting basket.

これを要するに、本発明は、廃棄物を移送するベルトコンベアのベルトの中央部を両端部分より下方に突出させて断面半円形状にすると共に、このベルトコンベアの上に、所定間隔離間して廃棄物選別用ロールを取付け、この廃棄物選別用ロールの回転軸を、ベルトの進行方向と平行に配置し、当該廃棄物選別用ロールに、複数の弾性部材の基端部を取付け、当該弾性部材の先端部に廃棄物選別用杆を取付け、廃棄物選別用杆の先端とベルトコンベアのベルトとの間隙をベルトコンベアの上流側に取付けるものほど広くする。
よって、大きさ、材質の異なるものが混在した廃棄物を、大きさにより連続して選別できると同時に、弾性部材の弾性率を適宜変えて重さによる選別も行うことができる。
さらに、ベルトコンベアの廃棄物排出側端部を凸曲面にしたので、シート状の廃棄物などを、ベルトコンベアの端に引っ掛けることなく円滑にベルトの外に掃出できる。 In short, according to the present invention, the central portion of the belt of the belt conveyor for transferring waste is projected downward from both end portions into a semicircular cross section, and disposed on the belt conveyor at a predetermined interval. A waste sorting roll is attached, the rotation shaft of the waste sorting roll is arranged in parallel with the traveling direction of the belt, and a base end portion of a plurality of elastic members is attached to the waste sorting roll. A waste sorting basket is attached to the tip of the belt, and the gap between the tip of the waste sorting basket and the belt of the belt conveyor is made wider as it is attached to the upstream side of the belt conveyor.
Therefore, it is possible to continuously sort wastes mixed in different sizes and materials, and at the same time, sort by weight by appropriately changing the elastic modulus of the elastic member.
Furthermore, since the waste discharge side end of the belt conveyor has a convex curved surface, sheet-like waste and the like can be smoothly swept out of the belt without being caught on the end of the belt conveyor.

以下、本発明の実施形態について図面を参照して説明する。
図１は本発明の廃棄物選別装置の側面図であり、廃棄物の運搬が分かり易いよう、ベルトは底面のみを記載した。図２は、モータ及び動力伝達機構を省略した廃棄物選別用装置の正面図である。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a side view of the waste sorting apparatus of the present invention, and only the bottom surface of the belt is shown so that the transport of waste can be easily understood. FIG. 2 is a front view of the waste sorting apparatus in which the motor and the power transmission mechanism are omitted.

１はベルトコンベアであり、ベルト２は、中央部分を両端部分より下方に突出するように湾曲させて、断面半円形状にする（図２参照）。さらに、ベルトコンベア１の廃棄物排出側端部１４を凸曲面にする
３は一対の廃棄物選別用ロール取付台であり、ベルトコンベア１上を跨ぐようにそれぞれ載置する。
４は廃棄物選別用ロールであり、前記廃棄物選別用ロール取付台３，３間に回転自在に軸支するものである。
さらに、この廃棄物選別用ロール４の外周に、放射状に複数本のコイルバネ１０を分散して配置する。そして、このコイルバネ１０の先端部に廃棄物選別用杆１１を固定する。
この廃棄物選別用杆１１の先端部は、円柱形等であってもよいが、廃棄物を掃出し易いようボートのオール状や熊手状にしてもよい。また、適宜コイルバネ１０に対し折曲して取り付けてもよい。
７はモータであり、動力伝達用ベルト８を介して前記廃棄物選別用ロール４の中心に固定した回転軸９に動力を伝達する。 Reference numeral 1 denotes a belt conveyor, and the belt 2 is curved so that a central portion protrudes downward from both end portions to have a semicircular cross section (see FIG. 2). Further, the waste discharge side end portion 14 of the belt conveyor 1 is formed into a convex curved surface. Reference numerals 3 denote a pair of waste sorting roll mounts, which are respectively placed so as to straddle the belt conveyor 1.
A waste sorting roll 4 is rotatably supported between the waste sorting roll mounts 3 and 3.
Further, a plurality of coil springs 10 are radially distributed on the outer periphery of the waste sorting roll 4. A waste sorting basket 11 is fixed to the tip of the coil spring 10.
The tip of the waste sorting basket 11 may have a cylindrical shape or the like, but may be in the shape of a boat or a rake so that the waste can be easily swept out. Further, the coil spring 10 may be bent and attached as appropriate.
A motor 7 transmits power to a rotating shaft 9 fixed at the center of the waste sorting roll 4 via a power transmission belt 8.

前記コイルバネ１０は、隣接するコイルバネ１０との間隙を考慮した上で位置を調節して適宜固定する。
廃棄物選別用杆１１は、その先端とベルト２との間隙ｄを所定の寸法になるようにしてコイルバネ１０に固定する。廃棄物選別用杆１１の固定は、このコイルバネ１０と一体にするか、コイルバネ１０の先端部に連結筒５を介して着脱自在にする（図８）。
着脱自在の場合は、廃棄物選別用杆１１に廃棄物が絡まって取れなくなった場合や、廃棄物選別用杆１１が摩耗して短くなった場合でも、廃棄物選別用杆１１を取り外し、廃棄物を取除いたり、廃棄物選別用杆１１を交換したりするだけでよい。
なお、６は、コイルバネ１０を廃棄物選別用杆１１に固定するためのスクリュボルトである。 The coil spring 10 is appropriately fixed by adjusting the position in consideration of the gap with the adjacent coil spring 10.
The waste sorting basket 11 is fixed to the coil spring 10 so that the gap d between the tip and the belt 2 has a predetermined size. The waste sorting basket 11 is fixed integrally with the coil spring 10 or detachably attached to the tip of the coil spring 10 via the connecting cylinder 5 (FIG. 8).
In the case of detachable, the waste sorting basket 11 is removed and discarded even when the waste sorting basket 11 becomes tangled and cannot be removed, or even when the waste sorting basket 11 is worn and shortened. It is only necessary to remove the object or replace the waste sorting basket 11.
Reference numeral 6 denotes a screw bolt for fixing the coil spring 10 to the waste sorting basket 11.

さらに、廃棄物選別用杆１１の先端とベルト２との間隙ｄは、ベルトコンベア１の下流側ほど狭くする（図９）。すなわち、下流側ほど長い廃棄物選別用杆１１を固定する。
また、前記廃棄物選別用杆１１の先端とベルト２との間隙ｄが同じであれば、コイルバネ１０は、ベルトコンベア１の上流側に取付けるものほど弾性率を小にする。 Further, the gap d between the tip of the waste sorting basket 11 and the belt 2 is narrowed toward the downstream side of the belt conveyor 1 (FIG. 9). That is, the waste sorting basket 11 that is longer on the downstream side is fixed.
Further, if the gap d between the tip of the waste sorting basket 11 and the belt 2 is the same, the coil spring 10 is attached to the upstream side of the belt conveyor 1 so that the elastic modulus becomes smaller.

この廃棄物選別装置の廃棄物の選別（大きさ及び比重による選別）は、以下のとおりである。
先ず、ベルトコンベア１で搬送されてきた廃棄物１５が、廃棄物選別用ロール４の下に移動すると、廃棄物選別用杆１１とベルト２との間隙ｄより径が大である廃棄物１５１Ｈ，１５１Ｌは、廃棄物選別用杆１１と接触し、廃棄物選別用杆１１の回転に伴い上方へと搬送される。この搬送中に、重いもの１５１Ｈ（その重さにコイルバネ１０が耐えられず折曲するもの）はコイルバネ１０が折曲して（図６）掃出されず、そのままベルト２上を移動する。軽いもの１５１Ｌ（その重さにコイルバネ１０が耐えて折曲しないもの）は、廃棄物選別用杆１１と接触したまま搬送されてベルト２外へ掃出される（図５）。
上記間隙ｄより径が小である廃棄物１５２は、廃棄物選別用杆１１と接触しないか、一旦接触しても廃棄物選別用杆１１が回転する途中で、間隙ｄより落下し、いずれも掃出されることなくベルト２上を移動する（図７）。
廃棄物選別用杆１１とベルト２との間隙ｄを上流側ほど広くすると、廃棄物は径の大きいものより順次掃出される。
さらに、コイルバネ１０の弾性率を、間隙ｄが同じであれば、上流側ほど小にすると、軽い（比重の小）ものから順に掃出される。
よって、上流側ほど大きくて比重が小のものが排出される。
廃棄物選別用杆１１の先端とベルト２との間隙ｄを、最終的に略０にすると、微小な廃棄物まで円滑に選別できる。
掃出した（選別した）廃棄物１５１Ｌは、ベルトコンベア１に併設された排出用ベルトコンベアで所定の容器（図示せず）に向け搬送する。 The sorting of waste (sorting by size and specific gravity) of this waste sorting apparatus is as follows.
First, when the waste 15 conveyed by the belt conveyor 1 moves below the waste sorting roll 4, the waste 151H having a diameter larger than the gap d between the waste sorting basket 11 and the belt 2 is disposed. 151L comes into contact with the waste sorting basket 11 and is conveyed upward as the waste sorting basket 11 rotates. During this conveyance, the heavy object 151H (the one that bends because the coil spring 10 cannot withstand its weight) bends the coil spring 10 (FIG. 6) and is not swept out but moves on the belt 2 as it is. A light thing 151L (one that the coil spring 10 withstands its weight does not bend) is conveyed while being in contact with the waste sorting basket 11 and is swept out of the belt 2 (FIG. 5).
The waste 152 having a diameter smaller than the gap d does not come into contact with the waste sorting basket 11 or falls through the gap d while the waste sorting bowl 11 is rotating even if it comes into contact. It moves on the belt 2 without being swept out (FIG. 7).
When the gap d between the waste sorting basket 11 and the belt 2 is increased toward the upstream side, the waste is sequentially swept away from the one having a larger diameter.
Further, if the elastic modulus of the coil spring 10 is the same as the gap d, the coil spring 10 is swept in order from the lighter (smaller specific gravity) when the gap is made smaller toward the upstream side.
Therefore, the larger upstream one with a smaller specific gravity is discharged.
When the gap d between the tip of the waste sorting basket 11 and the belt 2 is finally set to substantially zero, even fine waste can be sorted smoothly.
The swept (sorted) waste 151L is transported toward a predetermined container (not shown) by a discharge belt conveyor attached to the belt conveyor 1.

なお、前記実施形態では、廃棄物選別用杆１１を、コイルバネ１０の先端部に取付けているが、本発明はこれに限定されるものではなく、所定の弾性率を有する弾性部材の先端部に取付ければよく、板バネや棒状のゴム等の先端部に取付けてもよい。また、廃棄物選別用杆１１と弾性部材を同じ部材で一体に形成してもよい。
さらに、廃棄物選別用杆１１とコイルバネ１０は、間隙ｄ、弾性率を同じものを一列配列したのでは、一度廃棄物１５を掃出し損なうと以後そのまま掃出されないおそれがあるので、図４のように複数列設けるとよい。 In the above embodiment, the waste sorting basket 11 is attached to the tip of the coil spring 10. However, the present invention is not limited to this, and the tip of the elastic member having a predetermined elastic modulus is used. What is necessary is just to attach and you may attach to front-end | tip parts, such as a leaf | plate spring and rod-shaped rubber | gum. Further, the waste sorting basket 11 and the elastic member may be integrally formed of the same member.
Further, if the waste sorting basket 11 and the coil spring 10 are arranged in a row with the same gap d and the same elastic modulus, if the waste 15 is not swept out once, it may not be swept out as it is, as shown in FIG. It is preferable to provide a plurality of rows.
