Description

本発明は、廃タイヤのビード部からビードワイヤを抜取る装置に関し、特に、その抜取り動作を確実にして抜取り精度を大幅に向上させた廃タイヤのビードワイヤ抜取装置に関する。   The present invention relates to an apparatus for extracting a bead wire from a bead portion of a waste tire, and more particularly, to an apparatus for extracting a bead wire of a waste tire, which can improve the extraction accuracy by ensuring the extraction operation.

近時、自動車の普及によるタイヤの消費量は年間数十万トンを超えて大幅に増大する一方、消耗後の交換されたタイヤは野積みされ不法投棄されて社会問題となる場合もある。一方、タイヤのゴム成分は天然ゴムや石油を含み、燃やせばタイヤ1kgが重油0.8〜0.9リットルに相当し、硫黄分もC重油よりも低めであるから燃料としての利用価値が大きいことが周知である。また、従来困難であった成型後のタイヤの再生法が種々提案されており、例えば、廃タイヤを砕いて30メッシュ程度に粉砕した天然ゴム、スチレンブタジエンゴム、エチレンプロピレンゴムなどの合成ゴムの加硫物を可塑化し、新ゴムに加えるゴム材料として室温で簡単に再生させる方法がある。廃タイヤを燃料利用あるいは再資源化利用によらしめるとしても、タイヤにはホイルリムにタイヤを嵌合固定させるための多数回巻きの金属線条からなるビードワイヤが埋め込みされており、これを予め除去する作業が必要である。従来、廃タイヤからビードワイヤを抜取るための装置として、例えば、タイヤのビード線除去装置(特許文献1)や、廃タイヤのビードワイヤー抜取機(特許文献2)が提案されている。

Recently, the consumption of tires due to the widespread use of automobiles has increased significantly, exceeding several hundred thousand tons per year, while replaced tires after wear have been piled up and dumped illegally, which can become a social problem. On the other hand, the rubber component of the tire contains natural rubber and petroleum, and if burned, 1 kg of tire corresponds to 0.8 to 0.9 liters of heavy oil, and the sulfur content is lower than C heavy oil, so the utility value as fuel is great. It is well known. In addition, various methods for regenerating a molded tire, which have been difficult in the past, have been proposed. For example, a synthetic rubber such as natural rubber, styrene butadiene rubber, or ethylene propylene rubber obtained by crushing a waste tire and crushing to about 30 mesh has been proposed. There is a method of plasticizing a sulfide and regenerating it easily at room temperature as a rubber material to be added to a new rubber. Even if waste tires are used by fuel or recycling, tires are embedded with bead wires made up of multiple winding metal wires to fit and fix the tires on the wheel rim, and these are removed in advance. Work is necessary. Conventionally, as a device for extracting a bead wire from a waste tire, for example, a tire bead wire removal device (Patent Document 1) and a waste tire bead wire extractor (Patent Document 2) have been proposed.
Japanese Patent Laid-Open No. 50-109977 JP 2002-331524 A

上記の特許文献1のタイヤのビード線除去装置では、引抜き用ダイスに引抜き棒通過用ガイド孔と、同ガイド孔の左右両側に連通するビード線通過用型孔を設け、該ダイスのガイド孔に挿脱自在に貫挿した引抜き棒先端にビード線引き掛け部を設け、前記型孔のビード線引き込み口に、該ビード線を内蔵するゴム部を切削するための先鋭刃を突設させたものである。この特許文献1では、ビード線のみをダイスの左右両側のビード線通過用型孔内に強制的に引き込み、その引き込みに際して切開用先鋭刃によりビード部に付着したゴム部を削り取るから、ビード線の引き込み動作を円滑にし、かつビードワイヤへのゴム部の付着をなくして次工程処理を簡単に行なえるようにしたものである。しかしながら、図10に示すように、上向きフックにより廃タイヤの上端側内面部分を引っ掛けて引抜き棒で引き抜く場合、その強制引抜き動作により廃タイヤは大きく変形を受け、引抜き用ダイスの引抜き面に密着しながら未引抜き部分であるタイヤの下部LTを持ち上げる力が作用し、このため、ビードワイヤが引抜かれたタイヤの上部UTは、引抜き用ダイスの引抜き面に密着しながら上方に強烈な力で移動する力を受ける。そして、この密着部分Sにおいてゴムによる大きな摩擦力が生じる結果、その際の引抜き力にビード線が耐えきれず完全に廃タイヤからビード線が脱する前に断線し、結局、ビード線引抜き不完全の廃タイヤとなり引抜き装置の目的を達成できないという課題があった。ビード線引抜き不完全の廃タイヤは、例えば1mあるいは1.5mもの直径のタイヤでは燃料とするのには燃焼室への投入が困難であり、また1本70kg程度の重量物のため取り扱いの労力、運搬、搬送時の労力、運搬コストが高い等によりその処理に窮するものがあった。また、その際の駆動側負荷が極めて大きいため、引抜き棒と油圧シリンダとの連結部分を損壊しやすいものであった。さらに、図11に示すように、ビード線の引抜き時の廃タイヤは、極めて複雑な動きとなり、特にタイヤの両幅端側に埋め込まれたビード線が半円ぶん(中間位置)程度まで引抜かれた場合には抜き去られた部分のタイヤ重量が大きいためにその部分Rは鎖線示のように反転垂下し、その反転側の先端が引抜き用ダイスの引抜き面に接摺して摩擦抵抗を生じ、同様に、ビード線の引っ張り力負荷を大きくし、さらに駆動機構側への連結強度への不利な影響を生じさせる要因となっていた。   In the tire bead wire removing device disclosed in Patent Document 1, a drawing rod passing guide hole and a bead wire passing mold hole communicating with the left and right sides of the guide hole are provided in the drawing die, and the guide hole of the die is provided in the guide hole of the die. A bead wire hooking portion is provided at the tip of a pulling rod that is removably inserted, and a sharp blade for cutting a rubber portion containing the bead wire is projected at a bead wire drawing port of the mold hole. is there. In this patent document 1, only the bead wire is forcibly drawn into the bead wire passage mold holes on both the left and right sides of the die, and the rubber portion adhering to the bead portion is scraped off by the sharp cutting blade at the time of drawing. The pull-in operation is made smooth, and the rubber layer is not attached to the bead wire so that the next process can be easily performed. However, as shown in FIG. 10, when the upper end side inner surface portion of the waste tire is hooked by the upward hook and pulled out by the pulling rod, the waste tire is greatly deformed by the forcible pulling operation, and is closely attached to the pulling surface of the drawing die. However, a force that lifts the lower LT of the tire, which is an undrawn portion, acts. Therefore, the upper UT of the tire from which the bead wire is drawn is a force that moves with a strong force upward while closely contacting the drawing surface of the drawing die. Receive. As a result of the large frictional force generated by the rubber at the contact portion S, the bead wire cannot withstand the pulling force at that time, and is completely disconnected before the bead wire is removed from the waste tire. There was a problem that the purpose of the pulling device could not be achieved. Incompletely drawn bead wire tires, for example, tires with a diameter of 1 m or 1.5 m, are difficult to put into the combustion chamber to use as fuel, and handling weight is 70 kg. However, there are things that are hesitant to process due to high labor and labor during transportation and transportation. Further, since the driving load at that time is extremely large, the connecting portion between the extraction rod and the hydraulic cylinder is likely to be damaged. Furthermore, as shown in FIG. 11, the waste tire when the bead wire is pulled out has a very complicated movement, and the bead wires embedded at both ends of the tire are pulled out to a semicircle (intermediate position). In this case, since the tire weight of the removed portion is large, the portion R hangs down as shown by the chain line, and the tip of the inverting side comes into contact with the drawing surface of the drawing die to generate a frictional resistance. Similarly, the pulling force load of the bead wire is increased, which further causes an adverse effect on the connection strength to the drive mechanism side.

また、特許文献2の廃タイヤのビードワイヤー抜取機では、回転する抜取り刃を用いてビードの抜取りを行なう構造の抜取り機が示されており、これによれば、ビードの引き出し用の溝の傾斜角度や、抜取り刃と回転体の外周接線との距離を特定して主にビード線にゴムが付着しないようにして負荷を軽減させたものであり、この文献2の装置においても、上記同様の引抜き用ダイスの引抜き面にタイヤが圧接されて大きな摺動抵抗となり、ビード破断、動力側連結機構部分への大きな負荷による早期破損、等の問題があった。また、回転体を基礎としたビード線抜き取り構成であるから、タイヤが周方向に振り回されるのを防止するために、タイヤのホルダ装置が必要となり、コスト高であるのみならず、例えばバスやトラック用等の大型のタイヤの場合にはそれを回転して引抜かせるだけの直径大きさの回転体を用いなければならず、装置の大型化、重量化を伴いこれもまた動力負荷を大きくして電力や燃料コストを高いものにしていた。   In addition, in the bead wire extractor for waste tires of Patent Document 2, an extractor having a structure for extracting a bead using a rotating extractor blade is shown. According to this, an inclination of a groove for extracting a bead is shown. The load is reduced by specifying the angle and the distance between the extraction blade and the outer peripheral tangent of the rotating body so that the rubber does not mainly adhere to the bead wire. The tire was pressed against the drawing surface of the drawing die, resulting in a large sliding resistance, and there were problems such as bead fracture and early breakage due to a large load on the power side coupling mechanism. In addition, since the bead wire extraction configuration is based on a rotating body, a tire holder device is required to prevent the tire from being swung around in the circumferential direction, which is not only expensive, but also, for example, a bus or a truck. In the case of large tires such as for use, a rotating body having a diameter large enough to rotate and pull out the tire must be used. Electricity and fuel costs were high.

本発明は、上記従来の課題に鑑みてなされたものであり、その1つの目的は、引抜き動作時の廃タイヤからのビードワイヤ引抜きを確実に行なわせ、装置の稼働効率を大幅に向上させることのできる廃タイヤのビードワイヤ抜取装置を提供することにある。また、本発明の他の目的は、簡単な構成により低廉なコストで正確に廃タイヤからビードワイヤを抜き取ることのできる廃タイヤのビードワイヤ抜取装置を提供することである。   The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to reliably pull out the bead wire from the waste tire during the pulling operation, thereby greatly improving the operating efficiency of the apparatus. An object of the present invention is to provide a bead wire drawing device for a waste tire. Another object of the present invention is to provide a waste tire bead wire extraction device that can accurately extract a bead wire from a waste tire at a low cost with a simple configuration.

上記の目的を達成するために、本発明は、機枠に取り付けられる引抜き用ダイスであり、ビードワイヤの引抜き位置に配置される廃タイヤ12がその引抜き面141にあてがわれる引抜き用ダイス14と、引抜き用ダイスに設けられたガイド孔24を介して出入自在に設けられ廃タイヤ12のビードワイヤWを引掛けるフック部16を含む引抜き作動装置20と、を含み、フック部16をビードワイヤWに引っ掛けてその引抜を行なう際に、その強制引抜き動作により当該廃タイヤ12が変形しながら引抜き用ダイス14の引抜き面141や機枠150に密着しつつ移動させられる際のダイスの引抜き面や機枠への摩擦接摺を防止する摩擦接摺防止手段(22)を備えたことを特徴とする廃タイヤのビードワイヤ抜取装置10から構成される。本発明のビードワイヤ抜取装置は、タイヤの内径孔に孔の中心軸方向に沿うように差し込んで、環状のビードワイヤを直線状に引抜くことにより廃タイヤからビードワイヤを抜取する装置ばかりでなく、円形に駆動されるフックによりワイヤを抜取るタイプの装置についても適用される。   In order to achieve the above object, the present invention is a drawing die attached to a machine frame, and a drawing die 14 in which a waste tire 12 disposed at a drawing position of a bead wire is applied to a drawing surface 141; A pulling operation device 20 including a hook portion 16 that is provided so as to be able to enter and exit through a guide hole 24 provided in a drawing die and hooks the bead wire W of the waste tire 12, and the hook portion 16 is hooked on the bead wire W. When the pulling is performed, the forced pulling operation causes the waste tire 12 to be deformed and moved to the drawing surface 141 or the machine frame of the die 14 when it is moved in close contact with the drawing surface 141 or the machine frame 150 of the drawing die 14. It comprises a bead wire pulling device 10 for waste tires, which is provided with friction contact prevention means (22) for preventing friction contact.The bead wire pulling device of the present invention is not only a device for pulling out the bead wire from the waste tire by inserting the inner diameter hole of the tire along the center axis direction of the hole and pulling out the annular bead wire linearly, but also in a circular shape. The present invention is also applicable to a device that pulls out a wire by a driven hook.

その際、摩擦接摺防止手段(22)は、引抜き用ダイス14の引抜き面141及び/又は機枠150に設けられビードワイヤWの引抜動作時に廃タイヤ12の当たりを受けながら強制引抜き動作による移動を案内する移動案内機構32からなるようにするとよい。移動案内機構32は、タイヤの当たる部分を自由移動案内させる手段であり、したがって、引抜き用ダイスと同じ平面上を直線的に案内する機構でも良いし、また、曲線的さらには屈曲状に移動案内させるものでもよい。また、移動案内の際の案内方向も実施上の不具合がない程度で自由に設定してよい。タイヤの当たる部分を自由移動案内させる手段としては、例えば1個又は複数の自由転動ローラをタイヤの当たりを受ける部分に設置したり、あるいは、転動体と案内レールとにより当たりを受ける部分全体が移動する移動台あるいはスライダ構成としても良い。   At that time, the frictional contact prevention means (22) is moved by the forced pulling operation while receiving the contact with the waste tire 12 during the pulling operation of the bead wire W provided on the pulling surface 141 and / or the machine frame 150 of the pulling die 14. It is good to comprise the movement guide mechanism 32 to guide. The movement guide mechanism 32 is a means for freely moving and guiding a portion where the tire hits. Therefore, the movement guide mechanism 32 may be a mechanism that linearly guides on the same plane as the drawing die, or may be curved and bent. You may make it. Further, the guidance direction for the movement guidance may be set freely as long as there is no problem in implementation. As a means for freely moving and guiding the portion that hits the tire, for example, one or a plurality of free rolling rollers are installed in a portion that receives the contact of the tire, or the entire portion that receives the contact by the rolling element and the guide rail is used. It is good also as a moving stand or slider structure which moves.

好ましくは、移動案内機構32は、引抜かれる廃タイヤ12の当たりを受けながら自由に回転又は移動自在に設けられた第1の回転部材34あるいは移動部材38を含むとよい。第1の回転部材34あるいは移動部材38の具体的な構成は任意に設定してもよい。例えば自由回転自在なローラとしたり、移動盤構成としても良い。さらに、自由回転自在なローラとする場合には、その配置、個数、大きさなども任意に決めることができる。   Preferably, the movement guide mechanism 32 may include a first rotation member 34 or a movement member 38 provided so as to freely rotate or move while receiving contact with the waste tire 12 to be pulled out. The specific configuration of the first rotating member 34 or the moving member 38 may be arbitrarily set. For example, a freely rotatable roller or a moving board configuration may be used. Further, in the case of a freely rotatable roller, its arrangement, number, size, etc. can be arbitrarily determined.

また、第1の回転部材34あるいは移動部材38は、少なくとも引抜き用ダイスのガイド孔の上部位置に設けられているとよい。これらの第1の回転部材あるいは第1の移動部材38は、さらにはワイヤの誘導孔26の横方向隣接位置あるいは下部位置にも設けるとなおよい。また、ガイド孔24の下部位置にも設けるとなおよい。   Further, the first rotating member 34 or the moving member 38 may be provided at least at the upper position of the guide hole of the drawing die. The first rotating member or the first moving member 38 is further preferably provided at a position adjacent to the lateral direction of the wire guide hole 26 or at a lower position. It is even better to provide the guide hole 24 at a lower position.

また、第1の回転部材34は、自由回転可能に併設された複数のローラ34A〜34Dであるようにするとよい。   The first rotating member 34 may be a plurality of rollers 34 </ b> A to 34 </ b> D provided so as to be freely rotatable.

さらに、ビードワイヤWの引抜き位置に配置される廃タイヤ12を挟んで引抜き用ダイス14の設置側から離隔した引抜き用ダイスの引抜き面141と対向位置に設けられ、ビードワイヤWの引抜動作時に引抜かれたタイヤの脱去部分121の当たりを受けつつ強制引抜き動作による移動を案内する第2の移動案内機構80を含むとよい。第2移動案内機構80は、ワイヤの引き抜き動作により力が加わる方向に向けてタイヤの脱去部分121の当たりを受けつつ、そのタイヤの当たりを受けつつ移動案内する第2の移動案内手段であり、例えば、直線的にワイヤを抜取る際には抜取動作時にタイヤを持ち上げる方向に力が加わるから、その際に加わる力に随伴して自由に上方に向けて移動案内する。第1移動案内機構と同様に、平面上を直線的に移動案内する機構でも良いし、また、曲線的さらには屈曲状に移動案内させるものでもよい。また、移動案内の際の案内方向も実施上の不具合がない程度で自由に設定してよい。タイヤの当たる部分を自由移動案内させる手段としては、例えば1個又は複数の自由転動ローラをタイヤの当たりを受ける部分に設置したり、あるいは、転動体と案内レールとにより当たりを受ける部分全体が移動する移動台あるいはスライダ構成としても良い。   Furthermore, it is provided at a position opposite to the drawing surface 141 of the drawing die separated from the installation side of the drawing die 14 with the waste tire 12 arranged at the drawing position of the bead wire W, and is drawn during the drawing operation of the bead wire W. It is preferable to include a second movement guide mechanism 80 that guides the movement by the forced pulling-out operation while receiving the hit of the tire removal portion 121. The second movement guide mechanism 80 is a second movement guide means that receives and strikes the tire removal portion 121 in a direction in which a force is applied by the wire pulling operation and receives the tire hitting. For example, when a wire is pulled out linearly, a force is applied in the direction in which the tire is lifted during the pulling operation, so that the movement is guided upward freely along with the force applied at that time. Similarly to the first movement guide mechanism, a mechanism that linearly moves and guides on a plane may be used, or a movement guide that is curved or bent may be used. Further, the guidance direction for the movement guidance may be set freely as long as there is no problem in implementation. As a means for freely moving and guiding the portion that hits the tire, for example, one or a plurality of free rolling rollers are installed in a portion that receives the contact of the tire, or the entire portion that receives the contact by the rolling element and the guide rail is used. It is good also as a moving stand or slider structure which moves.

好ましくは、第2移動案内機構80は、ビードワイヤWの引抜動作時に引抜かれて引抜き面141から離間側に離れるタイヤの脱去部分121の当たりを受けつつ上下方向に自由に回転又は移動自在に設けられた第2の回転部材あるいは移動部材82を含むとよい。   Preferably, the second movement guide mechanism 80 is provided so as to be freely rotatable or movable in the vertical direction while receiving contact with a tire removal portion 121 that is pulled out during the pulling operation of the bead wire W and moves away from the drawing surface 141. The second rotating member or the moving member 82 may be included.

また、第2の移動部材82はビードワイヤWの引抜動作時に引抜かれたタイヤの脱去部分121の当たりを受ける受部94全体が自由に移動し得るフリーコンベア体84からなるようにするとよい。   The second moving member 82 may be formed of a free conveyor body 84 that can freely move the entire receiving portion 94 that receives the contact of the removed portion 121 of the tire that is pulled out during the pulling operation of the bead wire W.

また、第2移動案内機構80は、引抜かれたタイヤの脱去部分121の当たりを受けつつ案内方向に向けて強制的に移動させる駆動機構96を含むとなおよい。   Further, the second movement guide mechanism 80 may further include a drive mechanism 96 that forcibly moves in the guide direction while receiving contact with the removed portion 121 of the extracted tire.

さらに、引抜き作動装置10は、引抜き用ダイス14に設けられたガイド孔24から進退自在に突出し廃タイヤ12のビードワイヤWを引掛けるフック部16を有する引抜きロッド18を含むとよく、廃タイヤを立てた状態で例えば横方向からフック部を挿脱させながら、ワイヤを引抜く構成に適用するようにしても良い。   Further, the pulling operation device 10 may include a pulling rod 18 having a hook portion 16 that protrudes forward and backward from a guide hole 24 provided in the pulling die 14 and hooks a bead wire W of the waste tire 12. For example, the present invention may be applied to a configuration in which the wire is pulled out while inserting and removing the hook portion from the lateral direction.

本発明の廃タイヤのビードワイヤ抜取装置は、機枠に取り付けられる引抜き用ダイスであり、ビードワイヤの引抜き位置に配置される廃タイヤがその引抜き面にあてがわれる引抜き用ダイスと、引抜き用ダイスに設けられたガイド孔を介して出入自在に設けられ廃タイヤのビードワイヤを引掛けるフック部を含む引抜き作動装置と、を含み、フック部をビードワイヤに引っ掛けてその引抜を行なう際に、その強制引抜き動作により当該廃タイヤが変形しながら引抜き用ダイスの引抜き面や機枠に密着しつつ移動させられる際のダイスの引抜き面や機枠への摩擦接摺を防止する摩擦接摺防止手段を備えた構成であるから、 引抜き動作時に、タイヤの引抜き用ダイス等への当たりによる摩擦力でビードワイヤに大きな引き抜き方向への応力が掛かり、断線するようなことがなく、引抜き動作時の廃タイヤからのビードワイヤ引抜きを確実に行なわせ、装置の稼働効率を大幅に向上させることが可能である。また、簡単な構成により低廉なコストで正確に廃タイヤからビードワイヤを抜き取ることができる。   The waste tire bead wire drawing device of the present invention is a drawing die attached to a machine frame, and is provided on a drawing die and a drawing die on which a waste tire arranged at a drawing position of the bead wire is applied to the drawing surface. A pull-out actuating device including a hook portion that is provided so as to be freely accessible through a guide hole formed therein and hooks a bead wire of a waste tire, and when the hook portion is hooked on the bead wire and is pulled out, The scrap tire is configured to have friction contact prevention means for preventing friction contact with the drawing surface of the die and the machine frame when the waste tire is deformed and moved while closely contacting the machine frame. Therefore, during the pulling operation, a large stress in the pulling direction is applied to the bead wire due to the frictional force caused by the tire hitting the drawing die. Ri, without such disconnected, the bead wire withdrawal from scrap tires during withdrawal operation was reliably carried out, it is possible to greatly improve the operating efficiency of the apparatus. Further, the bead wire can be accurately extracted from the waste tire at a low cost with a simple configuration.

また、その際の摩擦接摺防止手段は、引抜き用ダイスの引抜き面及び/又は機枠に設けられビードワイヤの引抜動作時に廃タイヤの当たりを受けながら強制引抜き動作による移動を案内する移動案内機構からなる構成とすることにより、簡単な構造で、メンテナンスコストもほとんど不要でありながら、確実に廃タイヤの当たり部分の動きを所要方向に移動案内して逃がしてやり、機枠や引抜き用ダイスに対するタイヤの摩擦接摺を防止し得る。   Further, the frictional contact prevention means at that time is provided from a moving guide mechanism which is provided on the drawing surface of the drawing die and / or the machine frame and guides the movement by the forced pulling operation while receiving a waste tire during the pulling operation of the bead wire. With this structure, it is simple and requires almost no maintenance costs, but it reliably guides the movement of the contact part of the waste tire in the required direction to escape, and the tire against the machine frame and the drawing die It is possible to prevent frictional contact.

また、移動案内機構は、引抜かれる廃タイヤの当たりを受けながら自由に回転又は移動自在に設けられた第1の回転部材あるいは移動部材を含む構成とすることにより、簡単な構造による廃タイヤの当たり部分の動きの確実な所要方向への移動案内の実効を図れる。   In addition, the movement guide mechanism includes a first rotating member or a moving member provided so as to freely rotate or move while receiving the contact of the waste tire to be pulled out. Effective movement guidance can be achieved in the required direction with certain movement of the part.

また、第1の回転部材あるいは移動部材は、少なくとも引抜き用ダイスのガイド孔の上部位置に設けられた構成とすることにより、ワイヤの引き抜き動作時にタイヤを上方に持ち上げる方向に力が加わる場合に効率よくタイヤの当たり部分の摩擦接摺回避のための移動案内を行なわせることができる。   In addition, the first rotating member or the moving member is provided at least at the upper position of the guide hole of the drawing die so that it is efficient when force is applied in the direction of lifting the tire upward during the wire drawing operation. It is possible to perform movement guidance for avoiding frictional contact at the tire contact part.

また、第1の回転部材は、自由回転可能に併設された複数のローラである構成とすることにより、タイヤの当たり部分の摩擦接摺回避のための移動案内の実効を確保しうる。   In addition, the first rotating member can be configured to be a plurality of rollers provided so as to be freely rotatable, so that it is possible to ensure the effectiveness of the movement guide for avoiding frictional contact at the contact portion of the tire.

また、ビードワイヤの引抜き位置に配置される廃タイヤを挟んで引抜き用ダイスの設置側から離隔した引抜き用ダイスの引抜き面と対向位置に設けられ、ビードワイヤの引抜動作時に引抜かれたタイヤの脱去部分の当たりを受けつつ強制引抜き動作による移動を案内する第2の移動案内機構を含む構成とすることにより、ビードワイヤの抜取時にタイヤの脱去部分がワイヤの抜取動作の大きな抵抗となることを防止し、ワイヤの断線を防止してワイヤの抜取達成率並びに装置の稼働効率を向上させ得る。   In addition, the tire removal part that is provided at the position opposite to the drawing surface of the drawing die separated from the installation side of the drawing die across the waste tire disposed at the drawing position of the bead wire and pulled out during the drawing operation of the bead wire By including the second movement guide mechanism that guides the movement by the forced pulling operation while receiving the hit, it is possible to prevent the removed portion of the tire from becoming a great resistance of the wire pulling operation when the bead wire is pulled out. The wire breakage can be prevented and the wire pulling achievement rate and the operation efficiency of the apparatus can be improved.

さらに、第2移動案内機構は、ビードワイヤの引抜動作時に引抜かれて引抜き面から離間側に離れるタイヤの脱去部分の当たりを受けつつ上下方向に自由に回転又は移動自在に設けられた第2の回転部材あるいは移動部材を含む構成とすることにより、簡単な構造による廃タイヤの脱去部分の当たり部分の動きの確実な所要方向への移動案内の実効を図れる。   Furthermore, the second movement guide mechanism is a second movement guide mechanism that is provided so as to be freely rotatable or movable in the vertical direction while receiving contact with the removed portion of the tire that is pulled out during the pulling operation of the bead wire and moves away from the drawing surface. By adopting a configuration including a rotating member or a moving member, it is possible to effectively carry out movement guidance in a required direction in which the movement of the contact portion of the removed portion of the waste tire has a simple structure.

また、第2の移動部材はビードワイヤの引抜動作時に引抜かれたタイヤの脱去部分の当たりを受ける受部全体が自由に移動し得るフリーコンベア体からなる構成とすることにより、簡単な構造による廃タイヤの脱去部分の当たり部分の動きの確実な所要方向への移動案内の実効を図れる。   Further, the second moving member is made of a free conveyor body in which the entire receiving part that receives the hit part of the removed part of the tire that is pulled out during the bead wire pulling operation can be freely moved. It is possible to effectively carry out the movement guidance in the required direction with certainty of the movement of the hit part of the tire removal part.

また、第2移動案内機構は、引抜かれたタイヤの脱去部分の当たりを受けつつ案内方向に向けて強制的に移動させる駆動機構を含む構成とすることにより、ビードワイヤの抜取時にタイヤの脱去部分がワイヤの抜取動作の大きな抵抗となることを防止する上に、ワイヤの抜取力を支援するあるいは補助する力を加えることにより、ワイヤの断線を防止してワイヤの抜取達成率並びに装置の稼働効率を飛躍的に向上させ得る。   In addition, the second movement guide mechanism includes a drive mechanism that forcibly moves in the guide direction while receiving a contact with the removed portion of the extracted tire, so that the tire is removed when the bead wire is withdrawn. In addition to preventing the part from becoming a great resistance to the wire pulling operation, by applying a force that supports or assists the wire pulling force, the wire breakage is prevented and the wire pulling achievement rate and the operation of the device are performed. Efficiency can be improved dramatically.

また、引抜き作動装置は、引抜き用ダイスに設けられたガイド孔から進退自在に突出し廃タイヤのビードワイヤを引掛けるフック部を有する引抜きロッドを含む構成とすることにより、廃タイヤを立てた状態で例えば横方向からフック部を挿脱させながら、ワイヤを引抜く構成に適用し得る。また、その結果、横方向引抜きタイプの既成のビードワイヤ抜取装置についても例えば引抜き用ダイスの交換等を行い、あるいは第2移動案内機構を設置するだけで、簡易に設置しうる。   Further, the pulling operation device includes a pulling rod having a hook portion that protrudes freely from a guide hole provided in the pulling die and hooks a bead wire of the waste tire, so that, for example, in a state where the waste tire is set up, The present invention can be applied to a configuration in which the wire is pulled out while inserting and removing the hook portion from the lateral direction. As a result, an existing bead wire drawing device of the horizontal drawing type can also be installed simply by exchanging the drawing die or installing the second moving guide mechanism.

以下、添付図面を参照しつつ本発明を実施するための最良の形態について説明する。図1ないし図7は、本発明の一つの実施の形態を示しており、本実施形態では、例えば、バスやトラック等の大型・重量物の廃タイヤの処理について適用した例を示す。図1において、本実施形態の廃タイヤのビードワイヤ抜取装置10は、縦型機枠150と横型機枠151に主要構成部材を配置させて設けられている。それぞれの機枠150、151は、図2、3に示すように、金属フレームを組み付けてそれぞれ中空立体長矩形形状に組み付けられている。   The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 7 show an embodiment of the present invention. In this embodiment, for example, the present invention is applied to the treatment of large and heavy waste tires such as buses and trucks. In FIG. 1, the waste tire bead wire pulling device 10 of the present embodiment is provided by arranging main components on a vertical machine casing 150 and a horizontal machine casing 151. As shown in FIGS. 2 and 3, each of the machine casings 150 and 151 is assembled into a hollow solid long rectangular shape by assembling a metal frame.

本実施形態の廃タイヤのビードワイヤ抜取装置10は、廃タイヤ12をあてがう引抜き面141を有する引抜き用ダイス14と、引抜き用ダイス14から出入自在に突出しビードワイヤWを引掛けるフック部16を含む引抜き作動装置20と、引抜き作動装置によるビードワイヤの引抜き時の引抜き面141に対する摩擦接摺を防止する摩擦接摺防止装置22と、を備え、これらは上記機枠150、151に組み込まれて設置されている。   The waste tire bead wire pulling device 10 according to the present embodiment includes a drawing die 14 having a drawing surface 141 to which the waste tire 12 is applied, and a pulling operation including a hook portion 16 that protrudes freely from the drawing die 14 and hooks the bead wire W. A device 20 and a frictional contact prevention device 22 for preventing frictional contact with the drawing surface 141 when the bead wire is pulled out by the drawing operation device are provided, and these are installed in the machine casings 150 and 151. .

図1において、縦型機枠150と横型機枠151とは側面視L字状に組み付けられ、縦型機枠150の対向する縦壁(四隅に配置した型鋼からなる隣接する金属フレームを含む仮想壁)の一方の壁の内のり面側には引抜き用ダイス14が固定されているとともに、この引抜き用ダイス14に連係して横型機枠151には引抜き作動装置20が設けられている。縦型機枠150は、図3,4にも示すように引抜き用ダイス14の縦長の第1取付壁150Aと空隙を空けて対向する位置に第2取付壁150Bが第1取付壁と平行に立てて設置されている。第1取付壁150Aと第2取付壁150Bとの空隙は、タイヤ幅より大きな空隙幅で、少なくとも挿入するタイヤの直径よりも小さな幅に設定され、この空隙に向けてビードワイヤを抜取処理すべき廃タイヤが転動されながら搬入されて側面側から出し入れされる。すなわち、この第1取付壁150Aと第2取付壁150Bとの空隙Gにおいて、廃タイヤのビードの抜取処理が行われる。第1取付壁150Aには横型機枠151が接合され、後述する引抜き用ダイス14の引抜き面に保持させたタイヤのビードワイヤWを引抜きさせる引抜き作動装置20が設置されている。   In FIG. 1, a vertical machine casing 150 and a horizontal machine casing 151 are assembled in an L-shape when viewed from the side, and are opposed to vertical walls facing the vertical machine casing 150 (virtual metal frames including adjacent metal frames made of steel plates arranged at four corners. A pulling die 14 is fixed to the inner surface of one wall of the wall), and a pulling operation device 20 is provided in the horizontal machine frame 151 in association with the pulling die 14. As shown in FIGS. 3 and 4, the vertical machine frame 150 has a second mounting wall 150 </ b> B parallel to the first mounting wall at a position facing the vertically long first mounting wall 150 </ b> A of the drawing die 14 with a gap. It is installed upright. The gap between the first mounting wall 150A and the second mounting wall 150B is set to a gap width larger than the tire width and at least smaller than the diameter of the tire to be inserted. The tire is carried in while being rolled, and is taken in and out from the side. That is, in the gap G between the first mounting wall 150A and the second mounting wall 150B, a bead sampling process for the waste tire is performed. A horizontal machine casing 151 is joined to the first mounting wall 150A, and a pulling operation device 20 for pulling out a bead wire W of a tire held on a pulling surface of a pulling die 14 described later is installed.

図2,3において、引抜き用ダイス14は、縦型機枠の第1取付壁150Aであって、その上下中央よりやや下方位置に取り付けられた、タイヤからのビードワイヤ引抜き時のタイヤの係留手段であり、本実施形態では、厚い鉄板を機枠としての両側の型鋼にまたがらせて固定させている。図1,4に示すように、第1取付壁150Aと第2取付壁150Bとの間が廃タイヤを挿入させて引抜き位置に保持させる保持空隙Gとされ、引抜き用ダイス14の保持空隙に面する部分がビードワイヤの引抜き面141とされる。図2,3において、引抜き用ダイス14の略中央位置には縦長のガイド孔24が形成されるとともに、該ガイド孔24に十字状に直交連通して横長の誘導孔26が両側に延びて形成されている。詳細には、ダイス本体のさらに上面にガイド孔24と誘導孔26とを十字状に穿孔したプレート28を固定している。   2 and 3, the drawing die 14 is a first mounting wall 150A of the vertical machine frame, and is a mooring means for the tire when pulling out the bead wire from the tire, which is attached at a position slightly below the center in the vertical direction. Yes, in this embodiment, a thick iron plate is fixed across the steel molds on both sides as the machine frame. As shown in FIGS. 1 and 4, a space between the first mounting wall 150 </ b> A and the second mounting wall 150 </ b> B is a holding gap G for inserting the waste tire and holding it in the drawing position, and faces the holding gap of the drawing die 14. The portion to be used is a bead wire drawing surface 141. In FIGS. 2 and 3, a vertically long guide hole 24 is formed at a substantially central position of the drawing die 14, and a horizontally long guide hole 26 is formed so as to extend in both sides in a cross shape in a cross shape. Has been. Specifically, a plate 28 having a guide hole 24 and a guide hole 26 drilled in a cross shape is fixed to the upper surface of the die body.

ガイド孔24は、後述する引抜き作動装置20のフック部16が外側から保持空隙Gに対して出入案内する孔であり、誘導孔に対して比較的に短い縦長孔からなり、処理のために立てて供給されるタイヤの円周頂部を引っ掛けるように上向き(あるいは斜め上向き)開口のフック部を保持空隙Gに対して進退させる。   The guide hole 24 is a hole through which the hook portion 16 of the pulling operation device 20 described later enters and exits the holding gap G from the outside. The guide hole 24 is a relatively long vertical hole with respect to the guide hole, and stands for processing. The hook portion having an upward opening (or obliquely upward) is moved forward and backward with respect to the holding gap G so as to hook the circumferential top portion of the tire to be supplied.

誘導孔26は、引抜き作動装置20によりタイヤから、数十本のピアノ線等の束を環状に形成したビードワイヤを引抜く際に、タイヤのビード部から離脱させたワイヤ部分の逃げ孔であり、ビードワイヤWを引っ掛けて縦長のガイド孔24から外部に向けて引っ張り込む際にタイヤのビード部から離脱したワイヤ部分がガイド孔内に収容しきれず、あるいは無理な力がビードワイヤに加えられてワイヤが引抜き途中で断線するのを防止する。さらに、ワイヤに付着したタイヤゴム片を削ぎ落とす機能を有する。実施形態において、図2に示すように、この横長の誘導孔26の上下縁に沿って上下受片30,31が平行に固定されている。上下受片30,31は、引抜き作動装置20のフック部16によりガイド孔24内に引き込まれるビードワイヤWを直接に受けながら誘導孔26へワイヤを引き込み案内させるものであり、本実施形態では、例えば上受片30はビードワイヤの保護用ワイヤネットのカッティング並びにワイヤに付着したタイヤゴム片の削ぎ落とし機能を有効に行なえるように例えば直角状のあるいは角をもったエッジ断面形状を有するとともに、下受片31は、70kg重量等のタイヤの円周頂部側のビードワイヤを引抜く際に引抜きの初期段階でタイヤの垂下端の重量によりワイヤが破断しないように曲面状のエッジ断面形状を有している。   The guide hole 26 is an escape hole of a wire portion that is separated from the bead portion of the tire when the bead wire in which a bundle of dozens of piano wires or the like is formed in an annular shape is pulled out of the tire by the pulling operation device 20. When the bead wire W is hooked and pulled outward from the vertically long guide hole 24, the wire portion that has been detached from the bead portion of the tire cannot be accommodated in the guide hole, or excessive force is applied to the bead wire and the wire is pulled out. Prevent disconnection on the way. Further, it has a function of scraping off the tire rubber piece attached to the wire. In the embodiment, as shown in FIG. 2, the upper and lower receiving pieces 30 and 31 are fixed in parallel along the upper and lower edges of the horizontally long guide hole 26. The upper and lower receiving pieces 30, 31 are for receiving and guiding the wire into the guide hole 26 while directly receiving the bead wire W drawn into the guide hole 24 by the hook portion 16 of the pulling operation device 20. In this embodiment, for example, The upper receiving piece 30 has, for example, a right-angled or angular edge cross-sectional shape so that the cutting function of the wire net for protecting the bead wire and the scraping function of the tire rubber piece attached to the wire can be effectively performed. No. 31 has a curved edge cross-sectional shape so that the wire does not break due to the weight of the bottom end of the tire when pulling out the bead wire on the circumferential top side of the tire, such as 70 kg weight.

本実施形態においては、特に、該引抜き用ダイス14の引抜き面側に移動案内機構32が設けられている。移動案内機構32は、ビードワイヤの引抜動作時に廃タイヤの当たりを受けながら強制引抜き動作によるタイヤの移動を案内する移動案内手段であり、移動を案内しつつタイヤが引抜き用ダイスあるいは機枠側と摩擦接摺するのを防止する摩擦接摺防止手段である。実施形態において、該移動案内機構32は、引抜かれる廃タイヤの当たりを受けながら自由回転自在に設けられた第1の回転部材34を含む。   In the present embodiment, in particular, the movement guide mechanism 32 is provided on the drawing surface side of the drawing die 14. The movement guide mechanism 32 is a movement guide means for guiding the movement of the tire by the forcible pulling operation while receiving a contact with the waste tire during the pulling operation of the bead wire, and the tire is frictioned with the drawing die or the machine frame side while guiding the movement. Friction contact / sliding prevention means for preventing contact. In the embodiment, the movement guide mechanism 32 includes a first rotating member 34 that is provided so as to be freely rotatable while receiving contact with a waste tire to be pulled out.

詳しくは、図2において、引抜き用ダイス14の引抜き面141側には同引抜き用ダイスのガイド孔24の上部位置に3個のフリーローラ34Aが横方向を支軸として自由回転自在に設けられている。そのうち、1個は他の2個よりも横長のローラでありプレート28の表面から転動面を前方側に突出させた状態で回転自在に軸支されている。また、他の2個のフリーローラ34Aは、プレート28に取り付けられたものよりも軸方向に短いローラであり、かつ横方向に離間して直列配置となるように引抜き用ダイス14にそれぞれ転動面を前方側に突出させた状態で自由回転自在に軸支されている。また、誘導孔26のそれぞれ外方側真横部分であって引抜き用ダイス14には2個のフリーローラ34Bが横方向を支軸としてそれぞれ自由回転自在に設けられている。さらに、誘導孔26の下方位置には、プレート28に2個のフリーローラ、さらにそれらの真横に2個のフリーローラ34Cが横方向を支軸として自由回転自在に設けられている。これらの第1回転部材は、横方向を支軸として自由回転し、処理すべきタイヤが引抜き面141にあてがわれてワイヤ引抜き作動される際にタイヤ全体が上方へ移動する力をそれらの転動面(転動受面)にタイヤを接触させて転動することにより接摺摩擦とすることなく転がり摩擦により極めてわずかな摩擦力でタイヤを移動させることができる。この第1回転部材34を含む移動案内機構32により、引抜き用ダイス14等にタイヤが摩擦接触してワイヤに大きな引張り応力が加わり破断することがないようにさせることができる。すなわち、移動案内機構32は、ビードワイヤの引抜動作時に廃タイヤの当たりを受けながら強制引抜き動作による移動を案内しつつタイヤの引抜き用ダイス14あるいは機枠150に対する摩擦接摺を防止する。   Specifically, in FIG. 2, three free rollers 34 </ b> A are provided on the drawing surface 141 side of the drawing die 14 at the upper portion of the guide hole 24 of the drawing die so as to be freely rotatable about the horizontal direction as a support shaft. Yes. Of these, one is a roller that is laterally longer than the other two, and is rotatably supported with the rolling surface protruding forward from the surface of the plate 28. The other two free rollers 34A are rollers shorter in the axial direction than those attached to the plate 28, and roll to the drawing dies 14 so as to be spaced apart in the lateral direction and arranged in series. The shaft is supported so as to be freely rotatable with the surface protruding forward. In addition, two free rollers 34B are provided on the drawing die 14 at the lateral sides of the guide holes 26 so as to be freely rotatable with the horizontal direction as a support shaft. Further, below the guide hole 26, two free rollers are provided on the plate 28, and two free rollers 34C are provided beside them so as to be freely rotatable with the horizontal direction as a support shaft. These first rotating members freely rotate about the horizontal direction as a support shaft, and when the tire to be processed is applied to the drawing surface 141 and the wire drawing operation is performed, the force that moves the entire tire upward is transferred to the first rotating member. The tire can be moved with a very small frictional force by rolling friction without rolling contact friction by rolling the tire in contact with the moving surface (rolling receiving surface). The moving guide mechanism 32 including the first rotating member 34 can prevent the tire from being brought into frictional contact with the drawing die 14 or the like to apply a large tensile stress to the wire and break the wire. That is, the movement guide mechanism 32 prevents frictional contact with the tire drawing die 14 or the machine frame 150 while guiding the movement due to the forcible pulling operation while receiving contact with the waste tire during the pulling operation of the bead wire.

本実施形態では、第1回転部材34は、誘導孔26の上部位置ばかりでなく、左右横並び位置、あるいは下部位置にも取り付けられているが、本実施形態のようにフック部によるひっぱり動作によりタイヤが上方に移動させられるビードワイヤの引き抜き態様では少なくとも、誘導孔26の上部位置に設置するとよい。また、第1回転部材34は1個のみ設けてもよいが、できるだけ広範囲にタイヤを受けて移動させるには複数個を分散させてタイヤの側面側を受けるように設けるのが良い。   In the present embodiment, the first rotating member 34 is attached not only to the upper position of the guide hole 26 but also to the left and right side-by-side positions, or the lower position. In the drawing mode of the bead wire that is moved upward, the bead wire is preferably installed at least at the upper position of the guide hole 26. Further, only one first rotating member 34 may be provided. However, in order to receive and move the tire as widely as possible, it is preferable to disperse a plurality of first rotating members 34 and receive the side surface of the tire.

本実施形態では、さらに引抜き用ダイス14の上部位置であって、機枠の第1取付壁150Aにも第1回転部材としてのフリーローラ34Dが横方向を支軸として自由回転自在に設けられている。フリーローラ34Dは、平行に立てられた第1取付壁150Aの左右の金属フレームの中間に支持板36を介して梯子状に設けられた他のフリーローラ34A〜34Cに比較して大径で軸方向に長いローラ体から構成されている。この機枠側のフリーローラ34Dも移動案内機構32の一部を構成し、タイヤの機枠側に対する摩擦接摺をも完全に防止させる。   In the present embodiment, a free roller 34D as a first rotating member is also provided on the first mounting wall 150A of the machine frame so as to be freely rotatable about the horizontal direction as a support shaft, which is also an upper position of the drawing die 14. Yes. The free roller 34D is larger in diameter than the other free rollers 34A to 34C provided in a ladder shape via a support plate 36 in the middle of the left and right metal frames of the first mounting wall 150A that is set up in parallel. It is composed of a roller body that is long in the direction. The machine frame side free roller 34D also constitutes a part of the movement guide mechanism 32, and completely prevents frictional sliding on the machine frame side of the tire.

なお、この移動案内機構32は、回転部材とすることなく例えば図9に示すように、引抜き動作時にタイヤを受けた状態で同タイヤの上方移動に随伴して移動する移動部材の構成としてもよい。図9の第1移動部材38は、例えばダイス本体の板状溝内に収容されて幅方向を決められた状態で、裏面側に転動体40を装架させた受部材42を含む構成からなり、上下に自由に移動可能に設けられてタイヤの移動を案内しつつ引抜き用ダイスや機枠との摩擦接摺を防止する。また、図示しないが、移動案内機構は、大きな摩擦抵抗を生じることのないようなスライダを設置し、これでタイヤを受けて抵抗を逃がすようにしても良い。   In addition, this movement guide mechanism 32 is good also as a structure of the moving member which moves according to the upward movement of the tire in the state which received the tire at the time of extraction operation | movement, for example, as shown in FIG. 9, without using it as a rotation member. . The first moving member 38 in FIG. 9 includes a receiving member 42 in which a rolling element 40 is mounted on the back surface side in a state where the width direction is determined by being accommodated in a plate-like groove of a die body, for example. It is provided so as to be freely movable up and down to prevent frictional sliding with the drawing die and the machine frame while guiding the movement of the tire. Although not shown, the movement guide mechanism may be provided with a slider that does not cause a large frictional resistance, so that the tire can be received to release the resistance.

図2に戻って、タイヤの保持空隙Gの下部位置には、タイヤを立てて挿入した状態から引抜き作動装置20による引抜き開始状態にセットするためのリフタ44が設けられている。リフタ44は、立てて挿入した廃タイヤの円周頂部側を引っ掛けてビードワイヤを引抜く際に、一端挿入したタイヤを少し持ち上げてフック部16の直線的な移動によりタイヤのビード部の内側に該フック部を挿入させるリフト手段である。本実施形態において、リフタ44は、駆動用油圧シリンダ46と、シリンダのロッド48に連結されて廃タイヤを立てた状態で安定的に受けるタイヤ受50から構成されている。タイヤ受50は前後に支持用アングル52を配置し、これを引抜き面141側に配置した受板54に固定させて構成されている。本実施形態では、図4に示すように、挿入して立てた廃タイヤ12が引抜き面側にその上端側を寄り掛らせる状態となるように、フリーローラ34Cの転動面左端位置はフリーローラ34Aの転動面左端位置よりも突出する位置に配置され、また、支持用アングル52も側面視で水平よりやや左上がり状態で設置されている。これにより、ビードワイヤの引抜き開始時にビードワイヤに対して大きな抵抗を生じさせないようにして引抜くことができ、動作の確実性を保持させる。また、56は、上下移動用ガイドである。   Returning to FIG. 2, a lifter 44 is provided at a lower position of the holding gap G of the tire to set the tire from the state where the tire is stood and inserted into a state in which the extraction is started by the extraction operation device 20. When the lifter 44 is hooked on the circumferential top portion of the waste tire inserted upright to pull out the bead wire, the lifted tire 44 is lifted up slightly and linearly moved by the hook portion 16 so that the bead wire is pulled inside. Lift means for inserting the hook portion. In the present embodiment, the lifter 44 includes a driving hydraulic cylinder 46 and a tire receiver 50 that is connected to a rod 48 of the cylinder and stably receives waste tires in a standing state. The tire receiver 50 is configured by disposing support angles 52 in the front and rear directions and fixing the support angles 52 to a receiving plate 54 disposed on the drawing surface 141 side. In the present embodiment, as shown in FIG. 4, the left end position of the rolling surface of the free roller 34 </ b> C is free so that the waste tire 12 that has been inserted and stood is in a state of leaning the upper end side against the drawing surface side. The roller 34A is disposed at a position protruding from the left end position of the rolling surface of the roller 34A, and the support angle 52 is also installed in a slightly upward left position in the side view. As a result, the bead wire can be pulled out without generating a large resistance when the bead wire is pulled out, and the reliability of the operation is maintained. Reference numeral 56 denotes a vertical movement guide.

図1に戻って、横型機枠151に設けられた引抜き作動装置20は、引抜き原動部58と、引抜き原動部により図1上左右方向に進退駆動される引抜きロッドとしての駆動ロッド18と、駆動ロッド18の先端に設けられたフック部16と、を含む。引抜き作動装置20は、保持空隙Gに保持された廃タイヤ12のビード部Fに埋め込み配置されているビードワイヤWを引抜き用ダイス14を当て部材として強制引抜させる引抜き作動手段であり、本実施形態において、引抜き用ダイス14に設けられたガイド孔24を介して出入自在に設けられ廃タイヤのビードワイヤWを引掛けるフック部16を含む。詳細には、引抜き原動部58は、横型機枠151に支持されて横方向に進退するロッド60を含む油圧シリンダ62と、を含み、ロッド60はタイヤの保持空隙Gから離間する方向に向けて進退移動するように該シリンダは配置されている。そして、該油圧シリンダ62のロッド60に屈曲部64を介して枢支連結されて引抜き用ダイス14側に対して進退移動する駆動ロッド18が設けられている。駆動ロッド18は図示しないブッシュによりその進退方向を位置決めされている。そして、該駆動ロッド18の先端側には、棒部材66の先端にフック部16を形成させたフック部材68がその棒部材66の基部側を連結して固定されている。   Returning to FIG. 1, the pulling operation device 20 provided in the horizontal machine casing 151 includes a pulling driving portion 58, a driving rod 18 as a pulling rod that is driven to move back and forth in the left-right direction in FIG. And a hook portion 16 provided at the tip of the rod 18. The drawing operation device 20 is a drawing operation means for forcibly drawing the bead wire W embedded in the bead portion F of the waste tire 12 held in the holding gap G by using the drawing die 14 as a contact member. The hook portion 16 is provided so as to freely enter and exit through a guide hole 24 provided in the drawing die 14 and hooks a bead wire W of a waste tire. Specifically, the pulling-out driving portion 58 includes a hydraulic cylinder 62 including a rod 60 supported by the horizontal machine casing 151 and moving back and forth in the lateral direction, and the rod 60 is directed in a direction away from the tire holding gap G. The cylinder is arranged to move forward and backward. A drive rod 18 that is pivotally connected to the rod 60 of the hydraulic cylinder 62 via a bent portion 64 and moves forward and backward with respect to the drawing die 14 side is provided. The drive rod 18 is positioned in the forward / backward direction by a bush (not shown). A hook member 68 in which the hook portion 16 is formed at the distal end of the rod member 66 is fixed to the distal end side of the drive rod 18 by connecting the base portion side of the rod member 66.

フック部16は、図1、図4に示すように、斜め右上方に開くフック70を有し、そのフックの内側凹部部分は切刃状に先鋭化されている。そして、廃タイヤ12を立てて保持空隙G内に挿入した状態で、タイヤのビード部Fの内側にフック70が位置するように引抜き作動装置によりセットされる。このフック部16は、図2に示すガイド孔24に大きなガタツキがない程度のクリアランスで出入自在となるように配置される。   As shown in FIGS. 1 and 4, the hook portion 16 has a hook 70 that opens obliquely upward to the right, and the inner recessed portion of the hook is sharpened in a cutting edge shape. Then, in a state where the waste tire 12 is erected and inserted into the holding gap G, it is set by the pulling operation device so that the hook 70 is positioned inside the bead portion F of the tire. The hook portion 16 is disposed so as to be freely accessible with a clearance such that the guide hole 24 shown in FIG.

さらに、本実施形態において、引抜き用ダイス14の引抜き面141と対向位置に離隔して第2の移動案内機構80が設けられている。第2移動案内機構80は、ビードワイヤWの引抜動作時に引抜かれて引抜き面から離間側に離れるタイヤの脱去部分の当たりを受けつつ強制引抜き動作による移動を案内する第2の移動案内手段であり、図1,3,7に示すように、本実施形態では、この第2移動案内機構80は、上下方向に自由に移動自在に設けられた第2の移動部材82を含む。詳細には、第1取付壁150Aに中間に廃タイヤが立てて挿入し得る程度の幅間隔を開けて対向位置に第1取付壁と同形状の長四角枠からなる金属フレームに画成されて第2取付壁150Bが立設されている。そして、該第2取付壁側であって金属フレームの内側にはフリーコンベア体84が上下動に自由移動可能に設けられている。フリーコンベア体84は、ビードワイヤの引抜動作時に引抜かれたタイヤの脱去部分121の当たりを受ける受部全体が自由に移動し得る第2移動部材であり、本実施形態では縦型機枠150の両縦枠の上下に離隔して取り付けられた支持ロッド86と、支持ロッドに固定したスプロケット88に調帯されて対向位置に2個設けられたテェーン90と、チェーン90を横に跨るように架設固定されてチェーン90の周回移動により自由に上下動する複数のスラット板92と、を含む。それぞれのスラット板92同士は受部の周回移動に支障を生じさせない程度の小さな幅間隔を空けて設けられ、タイヤの脱去部分が隙間に食い込まないようにしている。複数のスラット板92は図3,4に示すようにその板面を含む面が平面となるように配置されており、この複数のスラット板92により形成される面がビードワイヤWの引抜動作時に引抜かれたタイヤの脱去部分121の当たりを受ける受部94とされる。ビードワイヤWの引抜き時に同ワイヤを脱去されて拘束を失いながら離開側に密着するタイヤの脱去部分121は、引抜き力により上方に持ち上げられる力が作用する際に、該受部94全体がこの力をうけてワイヤの引抜き側による上昇させる力に随伴して上方に移動し、かつスプロケット88、チェーン90を含む案内機構により上方へ移動案内させる。なお、本実施形態では、第2移動案内機構80は、第2の移動部材としてのフリーコンベア体84から構成しているが、前記した第1の移動案内機構32と同様に、複数のローラを自由転動自在に設けるようにしてもよい。   Further, in the present embodiment, a second movement guide mechanism 80 is provided at a position facing the drawing surface 141 of the drawing die 14. The second movement guide mechanism 80 is a second movement guide means for guiding the movement by the forcible pulling operation while receiving a hit of the removed portion of the tire that is pulled out during the pulling operation of the bead wire W and moves away from the drawing surface. As shown in FIGS. 1, 3, and 7, in the present embodiment, the second movement guide mechanism 80 includes a second moving member 82 that is freely movable in the vertical direction. Specifically, the first mounting wall 150A is defined as a metal frame made of a long rectangular frame having the same shape as the first mounting wall with a width interval that allows the waste tire to be inserted in the middle. A second mounting wall 150B is erected. A free conveyor body 84 is provided on the second mounting wall side and inside the metal frame so as to be freely movable up and down. The free conveyor body 84 is a second moving member that can freely move the entire receiving portion that receives the contact of the removed portion 121 of the tire pulled out during the bead wire pulling operation. In the present embodiment, the free conveyor body 84 A support rod 86 that is attached to both vertical frames apart from each other, a chain 90 that is tuned by a sprocket 88 that is fixed to the support rod and that is provided at two opposing positions, and a chain 90 that extends across the chain 90 A plurality of slat plates 92 which are fixed and freely move up and down by the circular movement of the chain 90. The respective slat plates 92 are provided with a small width interval so as not to hinder the circumferential movement of the receiving portion, so that the removed portion of the tire does not bite into the gap. As shown in FIGS. 3 and 4, the plurality of slat plates 92 are arranged so that the surface including the plate surface is a plane, and the surface formed by the plurality of slat plates 92 is pulled when the bead wire W is pulled out. The receiving portion 94 receives the hit of the removed portion 121 of the extracted tire. When the bead wire W is pulled out, the removal portion 121 of the tire that is removed from the wire and loses its restraint and is in close contact with the separation side is subjected to a force that is lifted upward by the pulling force. The force is applied to move upward in accordance with the force to be raised on the drawing side of the wire, and is moved upward and guided by a guide mechanism including a sprocket 88 and a chain 90. In the present embodiment, the second movement guide mechanism 80 is composed of a free conveyor body 84 as a second movement member. However, like the first movement guide mechanism 32 described above, a plurality of rollers are provided. You may make it provide freely rolling freely.

さらに、本実施形態において、第2移動案内機構80は、引抜かれたタイヤの脱去部分121の当たりを受けつつ案内方向に向けて強制的に移動させる駆動機構96を含む。本実施形態において、駆動機構96は、ビードワイヤWの引抜き時に同ワイヤを脱去されて拘束を失いながら離開側に密着するタイヤの脱去部分121を引抜き時の上方持ち上げ力の有無に関わらず強制的にその脱去部分121を持ち上げ動作させる強制持ち上げ駆動手段であり、ワイヤの引抜き時のタイヤ全体の持ち上げ力を促進させる方向に機能する。これによって、ワイヤの脱去部分121を引抜き動作とは無関係に上方に持ち上げさせ移動案内させるから、タイヤの引抜き動作におけるワイヤへの異常に大きな負荷を完全に無くし、ワイヤの引抜き率を略100%に近づけることが可能となる。実施形態において、具体的には、この駆動機構96は、縦型機枠150の上端枠152に架設された駆動モータ98を含み、該駆動モータ98の回転軸と支持ロッド86のスプロケット88とを連動させるベルトプーリ機構とこれに連結されたチェーン90を介して受部94が上下駆動自在に設けられている。   Further, in the present embodiment, the second movement guide mechanism 80 includes a drive mechanism 96 that forcibly moves in the guide direction while receiving a contact with the removed portion 121 of the extracted tire. In this embodiment, the drive mechanism 96 forces the removed portion 121 of the tire that is removed when the bead wire W is pulled out and loses the restraint to adhere to the separation side, regardless of whether or not there is an upward lifting force when pulled out. In particular, it is a forced lifting drive means that lifts the removal portion 121 and functions in the direction of promoting the lifting force of the entire tire when the wire is pulled out. As a result, the removal portion 121 of the wire is lifted upward and guided by movement irrespective of the pulling operation, so that an abnormally large load on the wire in the tire pulling operation is completely eliminated, and the pulling rate of the wire is approximately 100%. It becomes possible to approach. In the embodiment, specifically, the drive mechanism 96 includes a drive motor 98 installed on the upper end frame 152 of the vertical machine casing 150, and includes a rotation shaft of the drive motor 98 and a sprocket 88 of the support rod 86. A receiving portion 94 is provided so as to be vertically movable via a belt pulley mechanism to be interlocked and a chain 90 connected thereto.

次に、本実施形態のビードワイヤ抜取装置の作用について説明する。引抜き用油圧シリンダ62を作動させてフック部16を引抜き用ダイスから退縮させ、その状態で例えば直径1メートル程度の廃タイヤを図3に示すように転がしながら図4,7のように、保持空隙Gに挿入させる。図4に示すように、その状態では廃タイヤの上部はその一側面側がダイス14の引抜き面141側に寄りかかるように係止している。次に、リフタ44の駆動用シリンダ46を駆動させタイヤ止め52を少し上昇させて停止し、その状態で、図1,4に示すように、引抜き用油圧シリンダ62を駆動させて駆動ロッド18の先端のフック部16を引抜き用ダイス14の引抜き面141から空隙G側に突設させ、廃タイヤの内孔に差し入れる。次に、リフタ44を下降させて図4に示すようにフック70の戻り内側部分であるフック部材68に廃タイヤ12全体を吊支させる。この状態から、引抜き用油圧シリンダ62を駆動させて駆動ロッド18並びにフック部16を引抜き用ダイス14の引抜き面141から引抜き動作する。この際、まず、フック部のフック70の先鋭刃体がタイヤの内壁側を突き刺し、そのまま駆動ロッド18が引き込まれると内蔵された環状のビードワイヤWの上端側一部を下側から引っ掛ける状態でフック70がガイド孔24内に引き込まれる。このとき、ビードワイヤはタイヤから強引に引き抜かれるのでタイヤはワイヤから引き剥がされる一方、ビードワイヤWは、横方向に長く設けられた誘導孔26から引き込まれて剥がされる(図6参照)。   Next, the operation of the bead wire extraction device of this embodiment will be described. The pulling hydraulic cylinder 62 is actuated to retract the hook portion 16 from the pulling die, and in this state, for example, as shown in FIGS. Insert into G. As shown in FIG. 4, in this state, the upper portion of the waste tire is locked so that one side surface thereof leans toward the drawing surface 141 side of the die 14. Next, the drive cylinder 46 of the lifter 44 is driven to raise and stop the tire stopper 52 a little, and in this state, as shown in FIGS. The tip hook portion 16 protrudes from the drawing surface 141 of the drawing die 14 toward the gap G and is inserted into the inner hole of the waste tire. Next, the lifter 44 is lowered and the entire waste tire 12 is suspended and supported by the hook member 68 which is the return inner portion of the hook 70 as shown in FIG. From this state, the extraction hydraulic cylinder 62 is driven, and the drive rod 18 and the hook portion 16 are extracted from the extraction surface 141 of the extraction die 14. At this time, first, the sharp blade body of the hook 70 of the hook portion pierces the inner wall side of the tire, and when the drive rod 18 is pulled as it is, the hook is engaged with a part of the upper end side of the built-in annular bead wire W from below. 70 is pulled into the guide hole 24. At this time, since the bead wire is forcibly pulled out from the tire, the tire is peeled off from the wire, while the bead wire W is pulled out from the guide hole 26 provided long in the lateral direction (see FIG. 6).

このとき、ビードワイヤの引抜き動作によりタイヤ全体が上方に持ち上げられ、摩擦接摺防止装置の第1移動案内機構32により、引抜き用ダイスの引抜き面141に密着接摺しようとするが、第1回転部材としての各フリーローラ34A〜34Dにより、縦方向の平面上を移動するように案内されて上方に移動し、タイヤが引抜き用ダイス14に接摺してビードワイヤに過度の引っ張り応力が加わることなく、引抜き動作が円滑に行われる。ビードワイヤの引抜きが進むと、例えば図11のようにワイヤを引抜かれたタイヤの脱去部分Rが拘束を失うが、このとき、引抜き面141に対向する位置に設置した第2移動案内機構80により、かつ、駆動モータの駆動力によってこの部分は第2移動部材82からなる受部94に密着状態で強制的に上部に持ち上げ駆動され、これによって、単にタイヤの脱去部分を受けて上方に自由移動させて案内させるだけではなく、タイヤ全体の重量負荷の軽減を行なうから、フック部による引抜き動作の補助を積極的に行うことにより、円滑にその引抜き作業を継続させることができる。そして、この実施形態では、廃タイヤからのビードワイヤの引抜き成功率は95%以上を達成することが実験的に確認されており、従来に比較して飛躍的に廃タイヤの再資源化、再利用時の材料としての利用しやすさを確保することができる。なお、第2移動案内機構は、駆動モータにより強制的に受部94を上昇移動させるようにしなくとも、単に、自由移動あるいは自由回動自在の構成としてもよい。そして、一方側のビードワイヤ引抜き処理を終了すると、空隙Gからタイヤを取り出し、反転させてワイヤ未引抜き側を引抜き面側に対向させるようにして再び空隙Gに挿入させて、上記と同様のワイヤ抜取処理を行うこととなる。   At this time, the entire tire is lifted upward by the bead wire pulling operation, and the first moving guide mechanism 32 of the frictional contact prevention device tries to make close contact with the drawing surface 141 of the drawing die. Each of the free rollers 34A to 34D is guided so as to move on the plane in the vertical direction and moves upward, so that the tire slides on the drawing die 14 and an excessive tensile stress is not applied to the bead wire. The drawing operation is performed smoothly. When the extraction of the bead wire proceeds, the removed portion R of the tire from which the wire has been pulled out loses its restraint as shown in FIG. 11, for example. At this time, the second movement guide mechanism 80 installed at a position facing the pulling surface 141 is used. And this part is forcibly lifted and driven to the upper part in close contact with the receiving part 94 made of the second moving member 82 by the driving force of the drive motor, so that it is free to move upward simply by receiving the tire removal part. Since the weight load of the entire tire is reduced as well as being moved and guided, the pulling operation can be continued smoothly by positively assisting the pulling operation by the hook portion. In this embodiment, it has been experimentally confirmed that the success rate of pulling out the bead wire from the waste tire is 95% or more, and the waste tire can be dramatically recycled and reused compared to the conventional case. Ease of use as time material can be ensured. Note that the second movement guide mechanism may simply be configured to be freely movable or freely rotatable without forcibly moving the receiving portion 94 upward by the drive motor. When the bead wire drawing process on one side is completed, the tire is taken out from the gap G, reversed, and inserted again into the gap G so that the undrawn wire side faces the drawing surface side. Processing will be performed.
