Abstract

<P>PROBLEM TO BE SOLVED: To make a device compact and to easily mount it also on existing equipment. <P>SOLUTION: The temporary storing device 21 is constituted by arranging a plurality of (two in this case) temporary storing means 32 parallel to each other in the lateral direction, and a linear body 16 is guided by a guiding means 39 from an outlet X of the temporary storing means 32a to an inlet N of the temporary storing means 32b. Due to this structure, when the length of the temporarily stored linear body 16 is equal to that of a conventional one, the length of the temporary storing device 21 in the longitudinal direction can be considerably shortened compared to the length of a conventional device, and to be precise, can be shortened to around the length obtained by dividing the longitudinal length of the conventional device by the number of the temporary storing means (two in this case). As a result, the entire temporary storing device 21 becomes compact. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
この発明は、長い線状体をフェスツーンを形成しながら一時的に貯留する一時貯留方法および装置に関する。
【0002】
【従来の技術】
【特許文献1】
特開2002−316769号公報
【0003】
本出願人は、近年、線状体の一時貯留装置として、前述の特許文献1に記載されているようなものを提案した。このものは、1本の直線上に配置され、回転軸が互いに平行なフリー回転する複数本の上側ローラと、隣接する上側ローラ間の直下にそれぞれ配置され、上側ローラに対して相対的に接近離隔可能で、回転軸が上側ローラに平行なフリー回転する複数本の下側ローラとを有し、長手方向に走行する線状体を上側、下側ローラに交互に順次掛け回すことでフェスツーンを形成するようにしたものである。
【0004】
そして、このものにおいては、上側、下側ローラを離隔限まで離隔させフェスツーンを最大長とすることで、該一時貯留装置に一時貯留される線状体の長さを、成形ドラムの周長と線状体の巻き付け回数との積とほぼ等長とし、これにより、成形ドラムへの線状体の巻き付け速度を高速化、例えば3.0m/sec以上としたときでも、一時貯留装置からの線状体の巻き出され過ぎを防止して、該一時貯留装置の破損を防止するようにしている。
【0005】
【発明が解決しようとする課題】
しかしながら、このような従来の線状体の一時貯留方法・装置は、一時貯留する線状体の長さがかなり長いため、一時貯留装置の長手方向長さ(上流端の上側ローラと下流端の上側ローラとの間の距離にほぼ等しい)も相当長くなり、この結果、装置全体が大型化して既存設備では設置空間を確保することが困難となるという問題点がある。
【0006】
この発明は、コンパクトで既存設備に対しても容易に設置することができる線状体の一時貯留方法および装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
このような目的は、第1に、横方向に並列配置され、回転軸が互いに平行なフリー回転する複数本の上側ローラと、隣接する上側ローラ間の直下にそれぞれ配置され、上側ローラに対して相対的に接近離隔可能で、回転軸が上側ローラに平行なフリー回転する複数本の下側ローラとを有する複数の一時貯留手段において、長手方向に走行する線状体を上側、下側ローラに交互に順次掛け回すことでフェスツーンを形成するとともに、誘導手段によって隣接する一時貯留手段のうち、一方の一時貯留手段の出口から送り出された線状体を他方の一時貯留手段の入口に導き、これにより、全ての一時貯留手段を同一線状体がフェスツーンを形成しながら順次通過するようにした線状体の一時貯留方法により達成することができる。
【0008】
第2に、横方向に並列配置され、それぞれが回転軸が互いに平行なフリー回転する複数本の上側ローラと、隣接する上側ローラ間の直下にそれぞれ配置され、上側ローラに対して相対的に接近離隔可能で、回転軸が上側ローラに平行なフリー回転する複数本の下側ローラとを有し、長手方向に走行する線状体を上側、下側ローラに交互に順次掛け回すことでフェスツーンを形成する複数の一時貯留手段と、隣接する一時貯留手段のうち、一方の一時貯留手段の出口から送り出された線状体を他方の一時貯留手段の入口に導く誘導手段とを備え、全ての一時貯留手段を同一線状体がフェスツーンを形成しながら順次通過するようにした線状体の一時貯留装置により達成することができる。
【0009】
この発明においては、フェスツーンを形成するために線状体が交互に順次掛け回される上側、下側ローラを有する複数の一時貯留手段を横方向に並列配置するとともに、誘導手段によって隣接する一時貯留手段の出口から入口に線状体を導くことで、全ての一時貯留手段を同一線状体がフェスツーンを形成しながら順次通過するようにしたので、一時貯留する線状体の長さが同一であるとき、一時貯留装置の長手方向長を従来装置よりかなり短く、詳しくは従来装置の長手方向長を一時貯留手段の数で除した長さ程度まで短くすることができ、これにより、装置全体がコンパクトとなって既存設備に対しても容易に設置することができる。
【0010】
また、請求項3に記載のように構成すれば、隣接する一時貯留手段の出口から入口へと線状体を誘導する際、該線状体の脱線、潰れ、折れ曲がり等を効果的に抑制することができる。
さらに、請求項4に記載のように構成すれば、線状体が走行中に脱線等を起こすことで該線状体に異常張力が発生したとき、これを検出して線状体の走行を緊急停止させることができる。
また、請求項5に記載のように構成すれば、異常張力検出手段を構造簡単で、かつ、安価に製作することができる。
【0011】
【発明の実施の形態】
以下、この発明の一実施形態を図面に基づいて説明する。
図1、2、3において、11は床面12上に設置された略上下方向に延びる支持フレームであり、この支持フレーム11の上下方向中央部には軸受13を介して巻きロール14が回転可能に支持され、この巻きロール14は円筒状のリール15と、該リール15の周囲に多数回ロール状に巻き取られた線状体16から構成されている。17は支持フレーム11の上端部に支持された巻き出しローラであり、この巻き出しローラ17には巻きロール14から巻き出された線状体16が掛け回されている。そして、この巻き出しローラ17は、支持フレーム11に固定されたモータ18から駆動力を付与されることで回転し、線状体16を引き取って巻きロール14から低速走行させながら次々と巻き出す。
【0012】
ここで、前記線状体16は、この実施形態においては、直線状に延びる少数本の互いに平行な非伸張性コードをコーティングゴムで被覆するとともに、その幅方向中央に縦溝を形成したリボン状体から構成しているが、コーティングゴムで被覆された1本の非伸張性コードであったり、あるいは、波状に屈曲する少数本の非伸張性コードをコーティングゴムで被覆したリボン状体であってもよい。
【0013】
19は支持フレーム11の一側に設置された拡縮径可能な円筒状の成形ドラムであり、この成形ドラム19は図示していない駆動機構により巻きロール14と平行な軸線回りに駆動回転される。そして、この成形ドラム19が回転しているとき、巻きロール14から巻き出された後、幅方向中央で2分割された線状体16が軸方向にずらされながら該成形ドラム19の軸方向両端部にそれぞれ供給されると、該線状体16は成形ドラム19に貼付けられているベルト層の幅方向両端部外側にそれぞれ螺旋状に巻き付けられ、ベルト補強層となる。
【0014】
21は巻きロール14と成形ドラム19との間に設置された一時貯留装置であり、この一時貯留装置21は床面12上に設置されるとともに、支持フレーム11から成形ドラム19に向かって延びる矩形枠状の固定フレーム22を有する。この固定フレーム22の上端部には左右方向、即ち、固定フレーム22の幅方向に離れた複数、ここでは2つの上側ローラ群23が設けられ、各上側ローラ群23は固定フレーム22に支持され、該固定フレーム22の長手方向に等距離離れた複数の上側ローラ24から構成されている。
【0015】
これらの上側ローラ24はいずれも同一高さに配置されるとともに、互いに平行な回転軸(巻きロール14の回転軸に平行な軸線)回りにフリー回転することができる。ここで、これら上側ローラ24はいずれも図4に示す検出ローラと同様に、軸方向両端にフランジを有するとともに、軸方向中央に向かうに従い大径となったクラウン付きローラから構成しており、これにより、線状体16がこれら上側ローラ24から脱線する事態を効果的に抑制することができる。
【0016】
26は固定フレーム22の一端部および他端部にそれぞれ敷設された上下方向に延びる複数対(2対)のガイドレールであり、これら2対のガイドレール26は前記上側ローラ群23に対応するよう左右方向に離れて配置されている。27は固定フレーム22の長手方向に沿って延びる水平な複数(2個)の可動フレームであり、これら可動フレーム27は前記上側ローラ群23に対応するよう左右方向に離れて設置されるとともに、その両端部がガイドレール26に摺動可能に係合することで、固定フレーム22に昇降可能に支持されている。この結果、これら可動フレーム27はガイドレール26にガイドされながら自重により下降することになるが、これら可動フレーム27にスプリング、エアシリンダ等を連結して、該可動フレーム27に下方に向かう弱い付勢力を付与するようにしてもよい。
【0017】
29は前記上側ローラ群23と対をなす複数(2個)の下側ローラ群であり、これらの下側ローラ群29は前記上側ローラ群23の直下にそれぞれ配置されている。各下側ローラ群29は可動フレーム27にそれぞれ支持された複数の下側ローラ30から構成され、これら下側ローラ30は前記上側ローラ24と同様形状のローラから構成されるとともに、前記上側ローラ24の回転軸と平行な回転軸回りにフリー回転することができる。また、これら下側ローラ30は前後方向に等距離離れるとともに、隣接する上側ローラ24間の直下にそれぞれ配置されている。そして、これらの下側ローラ30は可動フレーム27と一体的に昇降することで上側ローラ24に対して相対的に接近離隔することができる。
【0018】
前述した左右側にそれぞれ設置された上側ローラ24からなる上側ローラ群23、可動フレーム27、下側ローラ30からなる下側ローラ群29は全体として一時貯留手段32をそれぞれ構成し、この結果、これらの一時貯留手段32は複数(ここでは2個)設置されるとともに、横方向(左右方向)に離れて並列配置されていることになる。そして、各一時貯留手段32の上側、下側ローラ24、30には巻きロール14から巻き出された走行する線状体16が交互に順次掛け回されるが、このとき、上側、下側ローラ24、30は上下に離れているため、各一時貯留手段32には長い線状体16のフェスツーンが形成される。
【0019】
ここで、この実施形態では、右側および左側(図2において上側および下側)の一時貯留手段32a、bにおける線状体16の入口Nは共に一時貯留手段32a、bの長手方向他端部に位置し、一方、出口Xは一時貯留手段32a、bの長手方向一端部に位置している。この結果、隣接する2つの一時貯留手段32a、bの出口Xと入口Nとはそれぞれ一時貯留手段32a、bの長手方向一端部、他端部に設けられることになり、これら出口Xと入口Nとはほぼ一時貯留手段32の長手方向距離だけ大きく離れることになる。
【0020】
右側の一時貯留手段32aの出口X近傍には下側ローラ30に平行なガイドローラ35が設けられ、このガイドローラ35は固定フレーム22に回転可能に支持されている。該ガイドローラ35の直下の固定フレーム22には右側に向かって他側に若干傾斜した出口側誘導ローラ36が回転可能に支持され、この出口側誘導ローラ36はほぼ水平な回転軸回りにフリー回転することができる。一方、左側の一時貯留手段32bの入口N近傍には下側ローラ30に平行なガイドローラ37が設けられ、このガイドローラ37は固定フレーム22に回転可能に支持されている。
【0021】
該ガイドローラ37の直下の固定フレーム22には回転軸が前記出口側誘導ローラ36に平行な入口側誘導ローラ38が回転可能に支持され、この入口側誘導ローラ38もほぼ水平な回転軸回りにフリー回転することができる。ここで、これら出口側、入口側誘導ローラ36、38の回転軸はほぼ水平な同一平面上に配置されるとともに、出口側誘導ローラ36の軸方向中央と入口側誘導ローラ38の軸方向中央とを結ぶ直線は、これら出口側、入口側誘導ローラ36、38の回転軸に直角である。
【0022】
この結果、右側の一時貯留手段32aの出口Xから送り出された線状体16はガイドローラ35、出口側誘導ローラ36に順次掛け回されて走行方向が反転(ほぼ 180度方向転換)されるとともに、出口側誘導ローラ36により若干横方向、ここでは左方向に走行方向がずらされ、その後、直線的に走行して入口側誘導ローラ38まで誘導される。このようにして入口側誘導ローラ38に誘導された線状体16は該入口側誘導ローラ38に掛け回されることで、前述した横方向のずれが消失されて正規の走行方向に復帰するとともに、入口側誘導ローラ38、ガイドローラ37に順次掛け回されることで走行方向が反転され、その後、左側の一時貯留手段32bの入口Nに導かれる。
【0023】
前述したガイドローラ35、出口側誘導ローラ36、ガイドローラ37、入口側誘導ローラ38は全体として、隣接する一時貯留手段32のうち、一方(右側)の一時貯留手段32aの出口Xから送り出された線状体16を他方(左側)の一時貯留手段32bの入口Nに導く誘導手段39を構成する。なお、これらガイドローラ35、出口側誘導ローラ36、ガイドローラ37、入口側誘導ローラ38も前記上側ローラ24と同様形状のローラから構成されている。
【0024】
ここで、他側から一側に向かって走行する線状体を横方向に並列配置された2個の一時貯留手段において一時貯留する場合には、通常、以下のようにすると考えられる。即ち、該線状体を右側の一時貯留手段の長手方向一端部近傍まで導いた後、左右方向に離れ垂直軸回りに回転する2個のガイドローラに掛け回すことで走行方向を反転し、その後、該右側の一時貯留手段の長手方向一端部に設けられた入口に導く。
【0025】
そして、この右側の一時貯留手段においてフェスツーンを形成した後、長手方向他端部に設けられた出口から線状体を送り出すとともに、該出口近傍に設置され左右方向に離れるとともに垂直軸回りに回転する2個のガイドローラに掛け回すことで走行方向を反転し、その後、左側の一時貯留手段の長手方向他端部に設けられた入口に導く。そして、この左側の一時貯留手段においてフェスツーンを形成した後、長手方向一端部に設けられた出口から線状体を送り出すのである。
【0026】
しかしながら、このように垂直軸回りに回転するガイドローラによって走行方向を反転させながら右側の一時貯留手段の出口から左側の一時貯留手段の入口に誘導するようにすると、線状体が前述のようにある程度の幅のリボン状体であるとき、該線状体がガイドローラによって大きく捻られ、これにより、該線状体がローラから脱線したり、潰れや折れ曲がりが発生することがある。
【0027】
これに対し、前述のように一時貯留手段32a、bの出口X近傍、入口N近傍にそれぞれ、回転軸がほぼ水平な同一平面上に配置されるとともに、軸方向中央同士を結ぶ直線が回転軸に直角である出口側、入口側誘導ローラ36、38を設置し、一時貯留手段32aの出口Xから送り出された線状体16を出口側誘導ローラ36によって走行方向を若干横方向にずらした後、入口側誘導ローラ38まで誘導し、その後、該入口側誘導ローラ38によって前記横方向のずれを消失させた後、一時貯留手段32bの入口Nに導くようにすれば、線状体16に付与される捻れは僅かなものとなり、これにより、隣接する一時貯留手段32の出口Xから入口Nへと線状体16を誘導する際、該線状体16の脱線、潰れ、折れ曲がり等を効果的に抑制することができるとともに、線状体16のパス作業も容易となる。
【0028】
このように全ての一時貯留手段32において線状体16を上側、下側ローラ24、30に交互に順次掛け回すことでフェスツーンを形成するとともに、隣接する一時貯留手段32において線状体16を一方から他方に誘導するようにしたので、全ての一時貯留手段32を同一の線状体16がフェスツーンを形成しながら順次通過することとなり、この結果、これら全ての一時貯留手段32に一時貯留される線状体16の合計長さが非常に長くなる。そして、全ての下側ローラ30が下降限まで下降したとき、一時貯留装置21に一時貯留される線状体16の合計長さは、成形ドラム19(ベルト層)の周長と線状体16の巻き付け回数との積とほぼ等長となる。
【0029】
図1、4において、最終列の一時貯留手段32、ここでは左側の一時貯留手段32bの出口Xより下流側には異常張力検出手段42が配置され、この異常張力検出手段42は固定フレーム22の一端面でその上部に固定された水平な支持アーム43に設置されている。この異常張力検出手段42は前記支持アーム43の上面に固定されたスチール製の矩形板状をした固定部材としての支持プレート44を有し、この支持プレート44の上面には一対のブラケット45が取付けられている。
【0030】
46はブラケット45に両端部が支持された揺動ピンであり、この揺動ピン46の中央部は揺動アーム47の長手方向中央部に挿入されている。この結果、前記揺動アーム47は中央部、即ち、揺動ピン46を中心として揺動可能である。前記揺動アーム47の先端部には左側の一時貯留手段32bの出口Xから送り出された線状体16が掛け回されている検出ローラ48が回転可能に支持され、これにより、該線状体16は検出ローラ48においてその走行方向が反転される。
【0031】
一方、揺動アーム47の他端部にはマグネット50が取付けられ、このマグネット50は支持プレート44を吸着しているとき、揺動アーム47を水平な所定揺動位置に保持する。ここで、前記線状体16が一時貯留手段32において、例えば脱線して該線状体16に異常張力が発生すると、線状体16から検出ローラ48に付与される下向きの揺動力が過大となってマグネット50が支持プレート44から離脱し、これにより、揺動アーム47は揺動ピン46を中心として前記所定揺動位置から先端が下降するよう揺動する。
【0032】
51は前記揺動アーム47の揺動位置を常時検出する検出センサであり、この検出センサ51は前述のように線状体16の異常張力により揺動アーム47が、図4に仮想線で示す位置まで揺動して前記所定揺動位置から外れると、この揺動アーム47の揺動、即ち線状体16における異常張力の発生を検出して図示していない制御手段に検出信号を出力し、巻き出しローラ17、成形ドラム19の回転および線状体16の走行を緊急停止させる。前述した支持プレート44、ブラケット45、揺動ピン46、揺動アーム47、検出ローラ48、マグネット50、検出センサ51は全体として、一時貯留手段32の出口Xより下流側に設けられ、線状体16に異常張力が発生したとき、これを検出する前記異常張力検出手段42を構成する。
【0033】
そして、このように異常張力検出手段42を一時貯留手段32の出口Xより下流側に設けるようにすれば、線状体16が走行中に脱線等を起こすことで該線状体16に異常張力が発生したとき、これを検出して線状体16の走行を緊急停止させ、線状体16の断線、一時貯留手段32の破損等を防止することができるとともに、復旧作業を迅速に行うことができる。また、前述のように異常張力検出手段42を支持プレート44、ブラケット45、揺動ピン46、揺動アーム47、検出ローラ48、マグネット50、検出センサ51から構成するようにすれば、異常張力検出手段42を構造簡単で、かつ、安価に製作することができる。
【0034】
55は異常張力検出手段42の直下の固定フレーム22に回転可能に支持されたガイドローラ、56は異常張力検出手段42より一側の支持アーム43に回転可能に支持されたガイドローラ、57はガイドローラ56と成形ドラム19との間に設置されたフリー回転可能なガイドローラであり、前記線状体16は異常張力検出手段42の検出ローラ48を通過した後、ガイドローラ55、56、57に掛け回され、その後、成形ドラム19に供給される。ここで、ガイドローラ55とガイドローラ56との間を通過しているとき、線状体16は固定フレーム22の一端部に設置されたカッターを含む分割手段61により幅方向中央の縦溝において切断され、幅方向に2分割される。
【0035】
そして、このように2分割された線状体16は、成形ドラム19に貼付けられているベルト層の幅方向両端部外側にそれぞれ螺旋状に巻き付けられ、ベルト補強層となる。また、このように線状体16が幅方向に2分割されると、これら分割片における張力が成形ドラム19等からの影響を受けて互いに異なることがあるが、このような場合には、分割手段61とガイドローラ56との間の固定フレーム22に取付けられた張力修正手段62により張力が同一となるよう修正される。
【0036】
次に、この発明の一実施形態の作用について説明する。
今、成形ドラム19にカーカスプライ、ベルトプライ等のタイヤ構成部材が供給され、その外周に貼付けられているとする。このとき、モータ18により巻き出しローラ17が回転することで巻きロール14から低速で巻き出された線状体16は複数(2個)の一時貯留手段32に供給されるが、このように一時貯留手段32に供給された線状体16は各一時貯留手段32の上側、下側ローラ24、30に交互に順次掛け回されることでフェスツーンを形成しながら一時貯留される。
【0037】
このように巻きロール14から線状体16が次々と一時貯留手段32に供給されると、可動フレーム27、下側ローラ30がガイドレール26にガイドされながら下降してフェスツーンが徐々に長くなるが、このとき、線状体16が一時貯留手段32内において脱線等を起こし線状体16に異常張力が発生すると、マグネット50が支持プレート44から離脱するため、揺動アーム47は揺動ピン46を中心として先端が下降するよう揺動する。このように揺動アーム47が揺動すると、検出センサ51が該揺動を検出して巻き出しローラ17、成形ドラム19の回転および線状体16の走行を緊急停止させる。
【0038】
そして、線状体16の供給により前記下側ローラ30が下降限まで下降すると、一時貯留装置21に一時貯留される線状体16の合計長さが、成形ドラム19(ベルト層)の周長と線状体16の巻き付け回数との積とほぼ等長となり、一時貯留装置21には非常に長い線状体16が一時貯留される。
【0039】
ここで、一時貯留装置21を複数、ここでは2個の一時貯留手段32を横方向に並列配置することで構成するとともに、隣接する一時貯留手段32の出口Xから入口Nに線状体16を導くことで、全ての一時貯留手段32を同一線状体16がフェスツーンを形成しながら順次通過するようにしたので、一時貯留する線状体16の長さが同一であるとき、一時貯留装置21の長手方向長を従来装置よりかなり短く、詳しくは従来装置の長手方向長を一時貯留手段32の数(ここでは2)で除した長さ程度まで短くすることができ、これにより、一時貯留装置21全体がコンパクトとなって既存設備に対しても容易に設置することができる。
【0040】
そして、前述した長さの線状体16が一時貯留装置21に一時貯留されると、巻きロール14からの線状体16の巻き出しを停止するとともに、一時貯留手段32から線状体16を高速で引き出すが、このように一時貯留手段32から引き出された線状体16は分割手段61によって幅方向に2分割された後、成形ドラム19に供給されて該成形ドラム19上のベルト層の幅方向両端部外側にそれぞれ螺旋状に巻き付けられ、ベルト補強層となる。
【0041】
なお、前述の実施形態においては、巻きロール14から線状体16を巻き出して一時貯留装置21に一時貯留しているときには、成形ドラム19への線状体16の巻付けを停止する一方、成形ドラム19に対して線状体16を巻き付けているときには、巻きロール14からの線状体16の巻き出しを停止するようにしたが、この発明においては、成形ドラム19に対して線状体16を巻き付けながら、巻きロール14から線状体16を低速で巻き出すようにしてもよい。
【0042】
また、前述の実施形態においては、下側ローラ30を下降させることで一時貯留装置21のおける線状体16のフェスツーンを長くするようにしたが、この発明においては、下側ローラを静止させる一方、上側ローラを上昇させることで線状体のフェスツーンを長くするようにしてもよい。さらに、前述の実施形態においては、線状体16を2分割するとともに、これらをベルト層の幅方向両端部外側にそれぞれ螺旋状に巻き付けてベルト補強層としたが、この発明においては、線状体を分割することなく螺旋状に巻き付けてベルト層に重ね合わせるようにしてもよい。

It is formed.
[0004]
In this apparatus, the length of the linear body temporarily stored in the temporary storage device is defined as the peripheral length of the forming drum by separating the upper and lower rollers to the separation limit and setting the festoon to the maximum length. The product of the number of windings of the linear body is substantially equal to the length thereof, so that even when the winding speed of the linear body around the forming drum is increased, for example, 3.0 m / sec or more, the wire from the temporary storage device can be used. By preventing the state body from being unwound too much, the temporary storage device is prevented from being damaged.
[0005]
[Problems to be solved by the invention]
However, in such a conventional method for temporarily storing a linear body, since the length of the linear body to be temporarily stored is considerably long, the length in the longitudinal direction of the temporary storage device (the upper roller at the upstream end and the downstream (Which is almost equal to the distance between the upper rollers) is also considerably long. As a result, there is a problem that the entire apparatus becomes large and it becomes difficult to secure the installation space in existing equipment.
[0006]
An object of the present invention is to provide a method and an apparatus for temporarily storing a linear body that are compact and can be easily installed even in existing facilities.
[0007]
[Means for Solving the Problems]
Such an object is firstly arranged in parallel in the horizontal direction, and a plurality of upper rollers that rotate freely and whose rotation axes are parallel to each other, and are disposed immediately below adjacent upper rollers, respectively. In a plurality of temporary storage means having a plurality of lower rollers which can be relatively approached and separated, and the rotation axis of which is freely rotating in parallel with the upper roller, the linear body running in the longitudinal direction is moved to the upper and lower rollers. A festoon is formed by alternately and successively wrapping, and among the temporary storage means adjacent by the guiding means, the linear body sent out from the outlet of one temporary storage means is guided to the entrance of the other temporary storage means, and Accordingly, it is possible to achieve a temporary storage method of a linear body in which the same linear body sequentially passes through all the temporary storage means while forming a festoon.
[0008]
Second, a plurality of upper rollers that are arranged side by side in a horizontal direction and each of which rotates freely and whose rotation axes are parallel to each other, and are disposed immediately below adjacent upper rollers, respectively, and are relatively close to the upper rollers. It has a plurality of lower rollers that can be separated and has a free axis that rotates freely in parallel with the upper roller, and the festoon is formed by alternately successively winding the linear body running in the longitudinal direction on the upper and lower rollers. A plurality of temporary storage means to be formed, and a guide means for guiding a linear body sent from an outlet of one of the temporary storage means to an entrance of the other temporary storage means among adjacent temporary storage means, This can be achieved by a linear body temporary storage device in which the same linear body sequentially passes through the storage means while forming a festoon.
[0009]
In the present invention, a plurality of temporary storage means having upper and lower rollers on which a linear body is alternately and sequentially wound to form a festoon are arranged in parallel in a lateral direction, and the adjacent temporary storage means is guided by a guiding means. By guiding the linear body from the outlet of the means to the inlet, the same linear body sequentially passes through all the temporary storage means while forming a festoon, so that the length of the linear body to be temporarily stored is the same. At one time, the longitudinal length of the temporary storage device can be considerably shorter than the conventional device, and in particular, the longitudinal length of the conventional device can be reduced to about the length of the temporary storage device divided by the number of temporary storage means. It is compact and can be easily installed on existing equipment.
[0010]
In addition, according to the third aspect, when the linear body is guided from the outlet of the adjacent temporary storage means to the inlet, derailment, crushing, bending, and the like of the linear body are effectively suppressed. be able to.
Further, according to the structure as described in claim 4, when abnormal tension is generated in the linear body due to derailment or the like during the travel of the linear body, the linear body is detected and the traveling of the linear body is detected. You can make an emergency stop.
Further, according to the fifth aspect, the abnormal tension detecting means can be manufactured with a simple structure and at a low cost.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIGS. 1, 2, and 3, reference numeral 11 denotes a support frame installed on a floor surface 12 and extending in a substantially vertical direction. A winding roll 14 is rotatable through a bearing 13 at the center of the support frame 11 in the vertical direction. The winding roll 14 is composed of a cylindrical reel 15 and a linear body 16 wound around the reel 15 many times in a roll form. Reference numeral 17 denotes an unwinding roller supported on the upper end of the support frame 11, and a linear body 16 unwound from the winding roll 14 is wound around the unwinding roller 17. The unwinding roller 17 rotates by being supplied with a driving force from a motor 18 fixed to the support frame 11, takes out the linear body 16, and unwinds one after another while running at a low speed from the winding roll 14.
[0012]
Here, in this embodiment, the linear body 16 is a ribbon-like member formed by covering a small number of parallel non-extensible cords extending linearly with a coating rubber and forming a longitudinal groove at the center in the width direction. It is composed of a body, but is a single non-extensible cord covered with coating rubber, or a ribbon-like body in which a small number of non-extensible cords bent in a wave shape are covered with coating rubber. Is also good.
[0013]
Reference numeral 19 denotes a cylindrical forming drum which is installed on one side of the support frame 11 and whose diameter can be enlarged and reduced. The forming drum 19 is driven and rotated around an axis parallel to the winding roll 14 by a driving mechanism (not shown). When the forming drum 19 is rotating, after being unwound from the winding roll 14, the linear body 16 divided into two at the center in the width direction is shifted in the axial direction, and both ends of the forming drum 19 in the axial direction are shifted. When the linear members 16 are supplied to the respective portions, the linear members 16 are spirally wound around the outer ends of both ends in the width direction of the belt layer adhered to the forming drum 19 to form a belt reinforcing layer.
[0014]
Reference numeral 21 denotes a temporary storage device installed between the winding roll 14 and the forming drum 19. The temporary storage device 21 is installed on the floor 12 and extends from the support frame 11 toward the forming drum 19. It has a frame-shaped fixed frame 22. At the upper end of the fixed frame 22, a plurality of, here two upper roller groups 23 separated in the left-right direction, that is, the width direction of the fixed frame 22, are provided, and each upper roller group 23 is supported by the fixed frame 22. The fixed frame 22 is composed of a plurality of upper rollers 24 that are separated by an equal distance in the longitudinal direction.
[0015]
Each of these upper rollers 24 is arranged at the same height, and can freely rotate around rotation axes parallel to each other (an axis parallel to the rotation axis of the winding roll 14). Here, like the detection roller shown in FIG. 4, each of these upper rollers 24 has a flange at both ends in the axial direction, and is constituted by a crowned roller having a larger diameter toward the center in the axial direction. Thereby, the situation where the linear body 16 derails from these upper rollers 24 can be effectively suppressed.
[0016]
Reference numeral 26 denotes a plurality of pairs (two pairs) of guide rails extending in the vertical direction, which are respectively laid on one end and the other end of the fixed frame 22. These two pairs of guide rails 26 correspond to the upper roller group 23. They are located apart in the left-right direction. Reference numeral 27 denotes a plurality of (two) horizontal movable frames extending along the longitudinal direction of the fixed frame 22. These movable frames 27 are set apart from each other in the left-right direction so as to correspond to the upper roller group 23. Both ends are slidably engaged with the guide rails 26 and are supported by the fixed frame 22 so as to be able to move up and down. As a result, the movable frame 27 descends by its own weight while being guided by the guide rail 26. However, a spring, an air cylinder, or the like is connected to the movable frame 27, and a weak urging force is applied to the movable frame 27 downward. May be added.
[0017]
Reference numeral 29 denotes a plurality of (two) lower roller groups that make a pair with the upper roller group 23, and the lower roller groups 29 are respectively disposed directly below the upper roller group 23. Each lower roller group 29 is composed of a plurality of lower rollers 30 each supported by a movable frame 27. These lower rollers 30 are composed of rollers having the same shape as the upper roller 24, and Can freely rotate around a rotation axis parallel to the rotation axis of the. The lower rollers 30 are separated from each other by an equal distance in the front-rear direction, and are respectively disposed immediately below the adjacent upper rollers 24. Then, these lower rollers 30 can be moved toward and away from the upper rollers 24 by moving up and down integrally with the movable frame 27.
[0018]
The above-described upper roller group 23 including the upper rollers 24 and the lower roller group 29 including the movable frame 27 and the lower roller 30 disposed on the left and right sides respectively constitute the temporary storage means 32 as a whole. The temporary storage means 32 are provided in plural (here, two), and are arranged side by side in the lateral direction (left and right direction). The running linear body 16 unwound from the winding roll 14 is alternately and sequentially wound around the upper and lower rollers 24 and 30 of each temporary storage means 32. At this time, the upper and lower rollers 24 and 30 are vertically separated from each other, so that a festoon of the long linear body 16 is formed in each temporary storage means 32.
[0019]
Here, in this embodiment, the inlets N of the linear bodies 16 in the right and left (upper and lower in FIG. 2) temporary storage means 32a, b are both connected to the other longitudinal ends of the temporary storage means 32a, b. On the other hand, the outlet X is located at one longitudinal end of the temporary storage means 32a, 32b. As a result, the outlet X and the inlet N of the two adjacent temporary storage means 32a, b are provided at one end and the other end in the longitudinal direction of the temporary storage means 32a, b, respectively. Is largely separated from the temporary storage means 32 by the distance in the longitudinal direction.
[0020]
A guide roller 35 parallel to the lower roller 30 is provided near the outlet X of the temporary storage means 32a on the right side, and the guide roller 35 is rotatably supported by the fixed frame 22. An outlet guide roller 36 slightly inclined to the other side toward the right side is rotatably supported by the fixed frame 22 immediately below the guide roller 35, and the outlet guide roller 36 rotates freely about a substantially horizontal rotation axis. can do. On the other hand, a guide roller 37 parallel to the lower roller 30 is provided near the entrance N of the left temporary storage means 32b, and the guide roller 37 is rotatably supported by the fixed frame 22.
[0021]
An inlet guide roller 38 whose rotation axis is parallel to the outlet guide roller 36 is rotatably supported on the fixed frame 22 immediately below the guide roller 37, and the inlet guide roller 38 also rotates about a substantially horizontal rotation axis. Can rotate freely. Here, the rotation axes of the exit-side and entrance-side guide rollers 36, 38 are arranged on a substantially horizontal plane, and the center of the exit-side guide roller 36 in the axial direction and the center of the entrance-side guide roller 38 in the axial direction. Are perpendicular to the rotation axes of the outlet-side and inlet-side guide rollers 36, 38.
[0022]
As a result, the linear body 16 sent out from the outlet X of the right-side temporary storage means 32a is sequentially wound around the guide roller 35 and the outlet-side induction roller 36, and the running direction is reversed (almost 180 degrees). The traveling direction is slightly shifted in the lateral direction, here to the left, by the exit-side guide roller 36, and thereafter, the vehicle travels linearly and is guided to the entrance-side guide roller 38. The linear body 16 guided by the inlet-side guide roller 38 in this manner is wrapped around the inlet-side guide roller 38, so that the above-described lateral displacement is eliminated and the linear body 16 returns to the normal traveling direction. The running direction is reversed by being sequentially wound around the inlet-side guide roller 38 and the guide roller 37, and thereafter guided to the inlet N of the left temporary storage means 32b.
[0023]
The above-described guide roller 35, outlet-side guide roller 36, guide roller 37, and inlet-side guide roller 38 are sent out from the outlet X of one (right side) temporary storage means 32a of the adjacent temporary storage means 32 as a whole. The guiding means 39 is configured to guide the linear body 16 to the entrance N of the other (left side) temporary storage means 32b. The guide roller 35, the outlet guide roller 36, the guide roller 37, and the inlet guide roller 38 are also formed of rollers having the same shape as the upper roller 24.
[0024]
Here, in the case where the linear body traveling from the other side toward one side is temporarily stored in two temporary storage units arranged in parallel in the lateral direction, it is generally considered that the following is performed. That is, after the linear body is guided to the vicinity of one end in the longitudinal direction of the temporary storage means on the right side, the traveling direction is reversed by hanging around two guide rollers which are separated in the left-right direction and rotate around the vertical axis, and thereafter , Leading to an inlet provided at one longitudinal end of the temporary storage means on the right side.
[0025]
Then, after forming the festoon in the temporary storage means on the right side, the linear body is sent out from the outlet provided at the other end in the longitudinal direction, and is installed near the outlet and separates in the left-right direction and rotates around the vertical axis. The running direction is reversed by being looped around two guide rollers, and then guided to the inlet provided at the other longitudinal end of the left temporary storage means. After the festoon is formed in the temporary storage means on the left side, the linear body is sent out from an outlet provided at one end in the longitudinal direction.
[0026]
However, if the running direction is reversed by the guide roller rotating about the vertical axis and the guide is guided from the outlet of the temporary storage means on the right side to the inlet of the temporary storage means on the left side as described above, the linear body is formed as described above. When the ribbon has a certain width, the linear body is largely twisted by the guide roller, which may cause the linear body to be derailed, crushed, or bent.
[0027]
On the other hand, as described above, near the outlet X and near the inlet N of the temporary storage means 32a and 32b, respectively, the rotation axes are arranged on the same substantially horizontal plane, and the straight line connecting the axial centers is the rotation axis. After the exit side and the entrance side guide rollers 36 and 38 are installed at right angles to the linear body 16 sent out from the exit X of the temporary storage means 32a, the running direction is slightly shifted in the lateral direction by the exit side guide roller 36. Then, after the sheet is guided to the inlet-side guide roller 38, and the lateral displacement is eliminated by the inlet-side guide roller 38, the guide is guided to the inlet N of the temporary storage means 32b. When the linear body 16 is guided from the exit X to the entrance N of the adjacent temporary storage means 32, derailing, crushing, bending, and the like of the linear body 16 are effectively performed. Restrain It is possible, it becomes easy path work of the linear body 16.
[0028]
In this way, in all the temporary storage means 32, the linear body 16 is alternately and sequentially wound around the upper and lower rollers 24, 30 to form a festoon, and the linear body 16 in the adjacent temporary storage means 32 has one side. , The same linear body 16 sequentially passes through all the temporary storage means 32 while forming a festoon, and as a result, is temporarily stored in all these temporary storage means 32. The total length of the linear body 16 becomes very long. When all the lower rollers 30 are lowered to the lower limit, the total length of the linear body 16 temporarily stored in the temporary storage device 21 is determined by the circumference of the forming drum 19 (belt layer) and the linear body 16. Is approximately equal to the product of the number of windings.
[0029]
1 and 4, an abnormal tension detecting means 42 is disposed downstream of the outlet X of the temporary storing means 32 in the last row, here, the temporary storing means 32b on the left side. It is mounted on a horizontal support arm 43 fixed at one end to its upper part. The abnormal tension detecting means 42 has a support plate 44 as a fixing member in the form of a rectangular steel plate fixed to the upper surface of the support arm 43, and a pair of brackets 45 is mounted on the upper surface of the support plate 44. Have been.
[0030]
Reference numeral 46 denotes a swing pin whose both ends are supported by a bracket 45. The center of the swing pin 46 is inserted into the center of the swing arm 47 in the longitudinal direction. As a result, the swing arm 47 can swing around the center, that is, the swing pin 46. At the tip of the swing arm 47, a detection roller 48 around which the linear body 16 sent out from the outlet X of the temporary storage means 32b on the left is hung rotatably supported, whereby the linear body In 16, the traveling direction is reversed by a detection roller 48.
[0031]
On the other hand, a magnet 50 is attached to the other end of the swing arm 47. The magnet 50 holds the swing arm 47 at a predetermined horizontal swing position when the support plate 44 is attracted. Here, when the linear body 16 is derailed in the temporary storage means 32 and abnormal tension is generated in the linear body 16, for example, the downward swinging power applied to the detection roller 48 from the linear body 16 is excessive. As a result, the magnet 50 is detached from the support plate 44, whereby the swing arm 47 swings about the swing pin 46 so that the tip is lowered from the predetermined swing position.
[0032]
Reference numeral 51 denotes a detection sensor which constantly detects the swing position of the swing arm 47. The detection sensor 51 is shown by a virtual line in FIG. When the swing arm 47 swings to the position and deviates from the predetermined swing position, the swing of the swing arm 47, that is, the occurrence of abnormal tension in the linear body 16 is detected, and a detection signal is output to control means (not shown). Then, the rotation of the unwind roller 17 and the forming drum 19 and the running of the linear body 16 are urgently stopped. The support plate 44, the bracket 45, the swing pin 46, the swing arm 47, the detection roller 48, the magnet 50, and the detection sensor 51 are provided on the downstream side of the outlet X of the temporary storage means 32 as a whole. The abnormal tension detecting means 42 for detecting when an abnormal tension is generated in the unit 16.
[0033]
If the abnormal tension detecting means 42 is provided on the downstream side of the outlet X of the temporary storage means 32 as described above, the linear body 16 may be derailed during traveling, causing the abnormal tension on the linear body 16. Is detected, this is detected, the traveling of the linear body 16 is stopped urgently, disconnection of the linear body 16, breakage of the temporary storage means 32, etc. can be prevented, and quick recovery work can be performed. Can be. If the abnormal tension detecting means 42 is constituted by the support plate 44, the bracket 45, the swing pin 46, the swing arm 47, the detection roller 48, the magnet 50, and the detection sensor 51 as described above, the abnormal tension can be detected. The means 42 can be manufactured with a simple structure and at low cost.
[0034]
Reference numeral 55 denotes a guide roller rotatably supported by the fixed frame 22 immediately below the abnormal tension detecting means 42, reference numeral 56 denotes a guide roller rotatably supported by the support arm 43 on one side of the abnormal tension detecting means 42, and reference numeral 57 denotes a guide. It is a freely rotatable guide roller installed between the roller 56 and the forming drum 19. After the linear body 16 passes through the detecting roller 48 of the abnormal tension detecting means 42, the linear body 16 is moved to the guide rollers 55, 56, 57. It is then fed to the forming drum 19. Here, when the linear body 16 is passing between the guide roller 55 and the guide roller 56, the linear body 16 is cut in the vertical groove at the center in the width direction by the dividing means 61 including a cutter installed at one end of the fixed frame 22. And divided into two in the width direction.
[0035]
The linear body 16 thus divided into two parts is spirally wound around the outer ends of both ends in the width direction of the belt layer attached to the forming drum 19 to form a belt reinforcing layer. Further, when the linear body 16 is divided into two in the width direction in this way, the tension in these divided pieces may be different from each other due to the influence of the forming drum 19 and the like. The tension is corrected by the tension correcting means 62 attached to the fixed frame 22 between the means 61 and the guide roller 56 so that the tension is the same.
[0036]
Next, the operation of the embodiment of the present invention will be described.
Now, it is assumed that tire constituent members such as a carcass ply and a belt ply are supplied to the forming drum 19 and are attached to the outer periphery thereof. At this time, the linear body 16 unwound from the winding roll 14 at a low speed by the rotation of the unwinding roller 17 by the motor 18 is supplied to a plurality (two) of the temporary storage means 32. The linear body 16 supplied to the storage means 32 is temporarily stored alternately around the upper and lower rollers 24 and 30 of each temporary storage means 32 while forming a festoon.
[0037]
When the linear body 16 is successively supplied from the winding roll 14 to the temporary storage means 32, the movable frame 27 and the lower roller 30 descend while being guided by the guide rail 26, and the festoon becomes gradually longer. At this time, when the linear body 16 is derailed in the temporary storage means 32 and abnormal tension is generated in the linear body 16, the magnet 50 separates from the support plate 44, and the swing arm 47 is moved to the swing pin 46. Swing around the tip so as to descend. When the swing arm 47 swings in this way, the detection sensor 51 detects the swing and stops the rotation of the unwind roller 17 and the forming drum 19 and the running of the linear body 16 in an emergency.
[0038]
When the lower roller 30 is lowered to the lower limit by the supply of the linear body 16, the total length of the linear body 16 temporarily stored in the temporary storage device 21 is equal to the circumferential length of the forming drum 19 (belt layer). The length of the linear body 16 is approximately equal to the product of the number of times the linear body 16 is wound, and the very long linear body 16 is temporarily stored in the temporary storage device 21.
[0039]
Here, the temporary storage device 21 is configured by arranging a plurality of temporary storage devices 32 in this case in parallel in the lateral direction, and the linear body 16 is connected from the outlet X to the entrance N of the adjacent temporary storage device 32. Since the same linear bodies 16 sequentially pass through all the temporary storage means 32 while forming a festoon by guiding, when the length of the linear bodies 16 to be temporarily stored is the same, the temporary storage device 21 is used. Can be considerably shorter than the conventional device, and more specifically, the length in the longitudinal direction of the conventional device can be reduced to about the length obtained by dividing the number of temporary storage means 32 (here, 2). The whole 21 becomes compact and can be easily installed on existing equipment.
[0040]
When the linear body 16 having the above-described length is temporarily stored in the temporary storage device 21, the unwinding of the linear body 16 from the winding roll 14 is stopped, and the linear body 16 is temporarily stored from the temporary storage unit 32. The linear body 16 thus drawn out from the temporary storage means 32 is divided into two in the width direction by the dividing means 61, and then supplied to the forming drum 19 to form a belt layer on the forming drum 19. It is spirally wound around both ends in the width direction to form a belt reinforcing layer.
