Description

【0001】
【発明の属する技術分野】
本発明は物品を搬送する搬送装置に関し、詳しくは駆動ローラー式の搬送装置に関する。
【0002】
【従来の技術】
ローラー式の搬送装置、所謂ローラーコンベアはローラーを等間隔に並設して搬送面が構成されている。
その為、ベルトコンベアの搬送面となる幅広ベルトを使用していない為、ベルトの蛇行による搬送トラブルや、ベルトの摩耗によるベルト交換が不要になるという利点がある反面、搬送面を構成する並設されたローラー間には隙間が存在する為、搬送物の滓等がコンベア内(フレーム内)に入り易く、その為清掃を定期的に行なわなければならないが、コンベア内部の清掃は作業がし難い、という欠点があった。
【0003】
そこで、コンベア部を本体部から着脱可能に構成して、コンベア部を本体部から離した状態にし、そのような状態で清掃を行なえるようにすれば、前記清掃は行ない易くなる。
【0004】
【発明が解決しようとする課題】
しかし、コンベア部を構成する各ローラーは駆動させる必要があるが、本体部に駆動源を設ける場合には、着脱可能なコンベア部の各ローラーに駆動力を伝達する上手い方法がなく、実現できていないのが実状である。
更に、物品にラベルを貼り付けるラベル貼付装置に、物品搬送装置としてローラーコンベアを適用する場合には、ラベルを貼り付ける物品上の位置を好ましい位置にする必要があり、その為に物品の幅方向の位置を規制するガイドを移動させる良い駆動機構が存在しなかった。
【0005】
又、物品をガイドに沿わせる為にフリーのローラーをガイド方向に斜めに設けた場合に、物品の底面が均一でない場合は幅寄せが上手くいかないという不具合がある。
更に、ガイドの搬入側は拡開されており、物品の搬入位置がズレても問題なく物品を案内できるように構成されているが、物品のガイドへの当り方によっては該物品の搬送方向に対する向きが変わってしまうという問題を有する。
【0006】
本発明は上記した従来の技術が有する問題点に鑑みてなされたもので、その目的とするところは、ローラーを並設したコンベア部と駆動機構を装備した本体部を分離したタイプでありながら、コンベア部のローラーを確実に駆動できる搬送装置を提供することにある。
又、他の目的はコンベア部側に配置するガイドを、搬送路の幅方向に自由に移動調整できる装置を提供することにある。
更に、他の目的は、ローラー上を搬送される物品の底面が不均一でも確実に幅方向への移動(幅寄せ)を行なうことができる搬送装置を提供することにある。また、ガイドに対する当り方が変わっても、物品の方向が変わらないガイドを備えた搬送装置を提供することにある。
【0007】
【課題を解決するための手段】
上記目的を達成する為に本発明が講じた搬送装置の技術的手段は、 無端回動する駆動タイミングベルトを上面に巻装配置した本体部と、搬送ローラーを架設保持し、前記本体部の上面に対して着脱可能に装着されるコンベア部とから成り、コンベア部の各搬送ローラーには前記本体部の駆動タイミングベルトと噛合する受動プーリが取り付けられ、駆動タイミングベルトの回動によりコンベア部の搬送ローラーが受動プーリを介して駆動するように構成する(請求項1)。
それにより、コンベア部の各ローラーを本体部の駆動源により駆動でき、且つ本体部とコンベア部を着脱分離できるため、清掃を容易に行なうことが出来る。
【0008】
前記駆動タイミングベルトは、外周面の片面のみに歯が形成された片面歯タイミングベルトでも、内・外周面の両面に歯が形成された両面歯タイミングベルトの何れでもよい。但し、片面歯タイミングベルトの場合は、該タイミングベルトが巻回される駆動プーリにタイミングベルトを押し付けるローラーを設ける等の滑りを防止する処置を設ける必要がある。
又、駆動タイミングベルトとして両面歯タイミングベルトを使用した場合、タイミングベルトは本体部に架設した駆動プーリとコンベア部の受動プーリの両方に噛合させると共に、本体部にはコンベア部の受動プーリと上下対応する位置に支持プーリを架設支持する(請求項2)。これにより、駆動タイミングベルト自身を回動するための強いテンションを不要にできる。しかも、受動プーリによりタイミングベルトに面圧を加えても、本体部の対応位置には支持プーリが配置されているため、タイミングベルトのテンション(張り)はあまり変化せず、従ってコンベア部の着脱の際にタイミングベルトが外れる虞れは少ない。
【0009】
また、前記搬送装置のコンベア部には、該コンベアの搬送路における物品の位置(幅位置)を規制するガイドを設け、そのガイドは搬送ローラーの下方に配置した支持部材とローラー間の隙間を通して連結し、且つ前記支持部材は、本体部に設けた幅方向に移動自在な受け部材に対して接離自在とする(請求項3)。これにより、本体部に対して着脱分離自在なコンベア部側に配置したガイドの位置を、自動的に変更できる。
【0010】
前記ガイドは、コンベア部を本体部から分離した時、ブレーキ機構によりコンベア部に固定化され、コンベア部を本体部に載架連結した時はブレーキ機構が前記受け部材と当接して、該ブレーキ機構が解除されるようにする(請求項4)。それにより、コンベア部を本体部から取り外した時、ガイド位置はブレーキ機構で固定化されるため、再度、コンベア部を本体部に載架した時、受け部材と支持部材の位置合わせをする必要が無くなる。また、コンベア部を本体部に載架連結した時、前記ガイドのブレーキ機構は自動的に解除される為、ブレーキ操作を不要にできる。
【0011】
また、前記コンベア部における並設したローラーの間には、前記ガイドに向かって斜め方向に回転自在な幅寄せローラーと、その幅寄せローラーに対し搬送方向手前側位置に、搬送面が該幅寄せローラーの表面より上下に変化する異形ローラーを駆動回転自在に配置してもよい(請求項5)。この異形ローラーとしては、断面略菱形形状、或いは楕円形状、又は非円形ローラー等が挙げられる、要は、回転中心から外周面までの寸法に長短差がある形状のものであればよい。それにより、搬送される物品の底面が凸凹で均一でない場合でも、確実に幅寄せすることが出来る。
更に、前記ガイドは、コンベア部の始端側に向かって拡開するよう傾斜形成し、且つ物品の当接により更に拡開方向に開動可能に支持してもよい(請求項6)。この場合は、物品がガイドに当ると、ガイドが外側に向けて開く為、物品を転向させるモーメントが減少し、物品の転向を防止できる。また、物品が当った際の衝撃を緩和するのに作用する。
【0012】
また、前記した本体部とコンベア部の連結部に、両部の上下方向の間隔を変更し得る高さ変更手段を設け、その高さ変更手段の調整により前記駆動タイミングベルトの面圧を調整自在としてもよい(請求項7)。これにより、高さ変更手段の調整により、駆動タイミングベルトの面圧調整が可能となり、ローラーの回転を最適な状態に調整できる。
【0013】
【発明の実施の形態】
以下、本発明の実施の形態の一例を図面に基づいて説明する。
図1は本発明に係る搬送装置Aをラベル貼付装置Bに組み合わせ配置した平面図で、図中、Aはローラー式の搬送装置、Bはラベル貼付装置であり、ローラー式の搬送装置Aは駆動手段を備えた本体部A1と、搬送ローラーを架設保持したコンベア部A2とで構成されており、コンベア部A2は本体部A1の上面に着脱自在に装着されるように構成されている。
【0014】
以下、本体部A1と、コンベア部A2の詳細について説明する。
本体部A1は、図3及び図4に示すように、金属板(例えば、ステンレス板)で形成した外ケース1の内部に、金属板(例えば、ステンレス板)を用いて断面略コ字型に形成した本体フレーム2を収容配置し、その本体フレーム2における幅方向の一方の側壁(図面では右側)の上部に、駆動プーリ3が該フレーム2の長手方向の一側端部に支持され、本体フレーム2の底部上には駆動モータ4が配置されており、その駆動モータ4のプーリ4’と前記駆動プーリ3とに亘ってベルト5が巻回され、駆動モータ4の作動により駆動プーリ3が回転するように構成されている。
更に、前記駆動プーリ3の軸上及び本体フレーム2の長手方向に沿って支持プーリ6が等間隔に配置されると共に、フレームの左右端部に位置する支持プーリ6の下方に位置させてテンションプーリ7、7’が取り付けられ、そのテンションプーリ7、7’及び等間隔に配置した支持プーリ6とに亘って駆動タイミングベルト8が巻回されている。
これにより、駆動モータ4の回転力はプーリ4’→ベルト5→駆動プーリ3(支持プーリ6)を介して駆動タイミングベルト8に伝達され、支持プーリ6とテンションプーリ7、7’の外側を無端回動する。
【0015】
本体フレーム2の上縁に沿って等間隔に配置される支持プーリ6は、後述するコンベア部A2における搬送ローラーの支軸に固着した受動プーリと上下対応する位置に配置されている。
又、支持プーリ6及びテンションプーリ7,7’は、両面歯タイミングベルトからなる駆動タイミングベルト8の内面歯8aと噛合するように歯付きプーリ(スプロケット)で構成されている。
【0016】
更に、本体部A1の本体フレーム2には、後述するコンベア部A2側に装備される前後一対のガイドCを、コンベア部A2の搬送部における幅方向に移動調整する受け部材9、9’が移動自在に設けられている。
その受け部材9、9’は、本体フレーム2の前後側壁と前後側壁間に起立固定した中間起立壁14、14’に亘って上下平行に横架した案内支柱10とボールネジ11、案内支柱10’とボールネジ11’に亘って架設支持した可動体15、15’に固着され、且つ前記左右のボールネジ11、11’は本体フレーム2の外側に配置したモータ12、12’によりベルト13、13’を介して駆動回転されるように構成されている。そして、前記左右のボールネジ11、11’の駆動回転で可動体15、15’が幅方向(前後方向)に移動調整され、受け部材9、9’も幅方向に移動調整される。
【0017】
そして、幅方向に移動する受け部材9、9’は、前記可動体の上面にコンベア部A2側に装備されるガイドに連結された支持部材と係脱するもので、平面部9aと、その平面部9aの左右側部に起立形成した突片部9bとで構成されている。
又、本体部A1とコンベア部A2の連結は、本体フレーム2の側壁内側に起立取り付けた受けプレート30の上縁に受け凹部31が所定の間隔をおいて2個形成され、その受け凹部31に、コンベア部A2のフレームに取り付けた軸32が嵌合することで載架保持され、且つコンベア部A2のフレーム側に取り付けたバックル形留め具33を、本体部A1の本体フレーム2の側壁に固着した掛片34に引っ掛けて止めることで、本体部A1とコンベア部A2は連結一体化される。
【0018】
前記本体部A1の上面に対して着脱自在に載架されるコンベア部A2は、断面略門形に形成したフレーム16,16’を支柱20で所定の間隔に連結保持し、その所定の間隔をおいて対峙するフレーム16,16’間に搬送ローラー17が所定のピッチ間隔で回転自在に架設され、その各搬送ローラー17の軸17’の一方端には、前記本体部A1に装備した駆動手段の駆動タイミングベルト8と噛合する受動プーリ18が固着されている。
コンベア部A2に架設されて搬送路を構成する搬送ローラー17の架設位置は、前記本体部A1に装備される駆動手段を構成する支持プーリ6の軸芯線上とし、且つ搬送ローラー17の軸17’に固着する受動プーリ18の外径は、前記支持プーリ6及びテンションプーリ7,7’に亘って巻回された駆動タイミングベルト8の外周歯8bと噛合する径とする。それにより、コンベア部A2を本体部A1の上部に載架セットした場合、コンベア部A2の受動プーリ18は本体部A1の駆動タイミングベルト8の外周歯8bと噛合し、駆動タイミングベルト8の回動により回転され、各搬送ローラー17が駆動回転される。
【0019】
又、搬送ローラー17の並設で構成される搬送路には、搬送する物品Wの幅位置(搬送路の幅方向における物品の通る位置)を規制するガイドCが幅方向に移動自在に設けられている。
そのガイドCは、前記搬送ローラー17で構成される搬送路表面から所定高さ範囲内を仕切る起立壁を有した前後一対のガイド部材C1,C2で構成され、そのガイド部材C1,C2における起立壁の内面、即ち物品Wが当接する面はローラー19を回転可能ならしめて鉛直状に支持して摩擦抵抗を軽減するように構成されている。
又、前後一対のガイド部材C1,C2におけるコンベア部A2の始端側寄りの約1/3乃至1/2は、該コンベア部A2の始端側に向かって両ガイド部材C1,C2間の間隔が漸次幅広くなるよう外側に向けて傾斜形成され、物品Wの受け入れ搬送がスムーズに行なわれるように構成されている
【0020】
更に、前記ガイド部材C1,C2は、その長手方向の略中央位置が水平板21にピン22で回動可能に軸支されると共に、その軸支位置より下流側には物品Wが当ることで外側に回動したガイド部材を初期位置に復帰させるバネ23が装着されている。
【0021】
そして、上記の如く構成したガイド部材C1,C2は、搬送ローラー17より下側に位置して前後一対のフレーム16,16’を連結する複数本(図示は3本)の支柱20a,20b,20cに亘って幅方向に移動可能に架設した支持部材24,24’に連結され、該支持部材24,24’の移動によりガイド部材C1,C2が幅方向に移動調整されるようになっている。
【0022】
上記支持部材24,24’は、金属平板を用いて断面略L字形の帯板状に形成され、その支持部材の長手方向の一側部を支柱20a,20bに貫通し、他側部には断面略U字形の案内片25が取り付けられ、その案内片25がフレーム16,16’を連結する支柱20cに嵌合されている。これにより、支持部材24,24’はフレーム16,16’間に架設された支柱20a,20b、20cに沿って移動可能に支持される。
【0023】
更に、上記支持部材24,24’における支柱20a,20bの間には、ブレーキ機構26が装備されている。
そのブレーキ機構26は、前記支柱20a,20bの中間に位置させて支持部材24,24’の天板内側に支杆26aが垂下固定され、その支杆26aに、断面略台形状(円錐の頂部を切断した形状)としたブレーキパッド26bが上下動自在に嵌合されており、コンベア部A2が本体部A1から分離された状態では、前記ブレーキパッド26bが不図示のバネにより下方に付勢されて下降して、その外周のテーパ面が前記支柱20a,20b間に嵌合当接し、支持部材24,24’の移動に制動が作用するように構成されている。又、コンベア部A2を本体部A1に載架連結した場合は、前記ブレーキパッド26bの下端面が前記受け部材9,9’の平面部9aに当接して鉛直方向に持ち上げられ、ブレーキパッド26bの外周テーパ面は支柱20a,20bから離れ、支持部材24,24’の移動を抑えていた制動力が解除され、受け部材9,9’の移動に伴って移動可能となる。従って、コンベア部A2を本体部A1から分離した場合、ガイド部材C1,C2を保持した支持部材24,24’は前記ブレーキ機構26の作用で、分離した時の位置に固定保持される。
【0024】
又、前記コンベア部A2の搬送路における搬送方向の中間位置には、幅寄せローラー27がフレーム16,16’間に所定間隔をおいて並設されている。
この幅寄せローラー27は、フレーム27aにローラー27bを回転自在に支持したもので、物品Wの幅寄せ方向に応じて前記ローラー27bの軸心を、搬送ローラー17の軸心に対して所定の角度傾斜させてフレーム27aをネジ止め固定する。従って、幅寄せローラー27は、前記したガイドCの位置、及び本搬送装置Aの下流側に配置される装置(図示の実施例はラベル貼付装置)への搬入方向に合わせて個々に調整する。
【0025】
更に、前記幅寄せローラー27に対し搬送方向手前側位置(上流側)及び前方位置(下流側)には、前記幅寄せローラー27の表面位置(搬送面)に対し搬送面が上下に変化する異形ローラー28,28’が配置されている。
この異形ローラー28,28’は、断面円形のローラーの外周面に、金属薄板を曲げ加工して略菱形筒に形成したもの、又は略菱形筒の成型品を被せて形成されており、これによりローラーの軸心から外周面までの距離が長短変化し、回転により搬送面が上下することになる。そして、異形ローラー28,28’は前記搬送ローラー17と同様に駆動回転するように構成されている。
従って、物品Wの底面が均一でないものでも、異形ローラー28,28’の作用で前記した幅寄せローラー27に当接させることが出来、確実な幅寄せが期待できる。尚、この異形ローラーは、幅寄せローラー27に対して上流側のみに配置してもよいものである。
【0026】
又、本体部A1に対しその上部に載架連結するコンベア部A2は、両部A1、A2の上下方向の間隔を一定に設定しても良いが、搬送する物品Wの重量等に応じて前記駆動タイミングベルト8の面圧を調整自在としてもよい。
即ち、駆動タイミングベルト8は本体部A1側の支持プーリ6の外周面に巻回され、そのタイミングベルト8の外周歯8bにコンベア部A2側の受動プーリ18が乗るため、該コンベア部A2が載架連結される上下方向の位置を上下方向に変化させることで、駆動タイミングベルト8の外周歯8bに乗る受動プーリ18の面圧を変えることが出来る。その構成は、本体部A1とコンベア部A2の連結部に、高さ変更手段29を設ける。
その高さ変更手段29は、図14(a)、(b)に示すように本体部A1とコンベア部A2の連結を行なうコンベア部A2のフレームに固着された軸32を、回転中心から外周面までの寸法に長短差がある偏心軸とする。それにより、軸32を回動して本体部A1の受け凹部31で支持される軸32の高さを低くした場合(図14(a)参照)と、軸32の高さを高くした場合(図14(b)参照)とで、駆動タイミングベルト8の外周歯8b上に乗る受動プーリ18の噛み合いに寸法Lの差が生じ、駆動タイミングベルト8に作用する面圧が変わる。
図中、35は、前記したガイドCを構成する前後一対のガイド部材C1,C2を幅方向に移動調整する受け部材9,9’の移動範囲を検出制御する位置検出センサで、内側方向及び外側方向の限界位置を検出するものである。
【0027】
上記の如く構成した搬送装置Aは、駆動タイミングベルト8を装備した本体部A1の上部に、前記駆動タイミングベルト8と噛合する受動プーリを軸上に有した搬送ローラー17が並列配置されたコンベア部A2を載架連結することで、コンベア部A2の搬送ローラー17は駆動回転され、物品Wは搬送される。
そして、搬送する物品Wを搬送路の幅方向における所定の方向に案内するガイドCが前記コンベア部A2に、幅方向に移動可能に設けられていることで、物品Wを目的の線上へ移動案内できる。しかも、そのガイドCは本体部A1に設けた幅方向に移動自在な受け部材と係着して連動する為、連結状態でガイドCの位置を自由に変更調整することが出来る。更に、ガイドはコンベア部A2を本体部A1から分離取り外した時、その位置がブレーキ機構で固定される為、再度連結する場合、両者の位置関係がずれることは無い。
更に、コンベア部A2に物品を幅方向に案内する幅寄せローラー及びその幅寄せローラーの手前側位置に搬送面が該幅寄せローラーの表面より上下に変化する異形ローラーを設けた場合は、物品の底面が均一でない物品でも確実に幅寄せして搬送できる。
【0028】
上記した本発明は図示した実施の形態に限定されるものではなく、下記の変更等は適宜自由である。
(a)ガイドCにおける物品Wとの接触面は、ローラーに限定されず、例えば摩擦係数の低い部材を貼り付けてもよい。
(b)支持プーリと受動プーリとは同一線上に配置されているが、これに限らず、例えば支持プーリを省いて、代わりに駆動タイミングベルトのテンションを一定にする機構を用いてもよい。
(c)ガイドCの位置は商品に応じて移動用のモータを作動させて変更するが、搬送する物品の番号をコンソール(図示省略)から入力すると、ガイドの幅方向位置に関する設定データを読み出して自動的に変更調整されるようにしてもよい。
(d)ブレーキはブレーキパッドの自重で行なってもよく、ブレーキの解除は前記したと同様、コンベア部を本体部にセットすることで、自重で下降するブレーキパッドが鉛直方向に持ち上げられ、ブレーキが解除されるようにする。
【0029】
【発明の効果】
本発明の搬送装置は請求項1記載の構成により、コンベア部の各搬送ローラーを本体部の駆動源(駆動タイミングベルト)により駆動でき、しかも、コンベア部を本体部と着脱自在に出来るのでローラー式搬送装置の清掃を容易に行なうことが出来る。又、タイミングベルトを利用している為、各搬送ローラーを駆動する構成を簡単にでき、しかも作動音は静かで、快適に使用できる。
そして請求項2記載の構成により、受動プーリにより駆動タイミングベルトに面圧を加えても、駆動タイミングベルトのテンションはあまり変化しない為、搬送ローラーは安定して回転すると共に、コンベア部の着脱の際に駆動タイミングベルトが外れる虞れが少ない。
【0030】
又、請求項3記載の構成により、本体部に対して着脱分離自在なコンベア部側に配置したガイドの位置を、自動的に変更することができる。
また、請求項4記載の構成により、コンベア部を本体部から取り外した時、ガイド位置はブレーキ機構で固定化されるため、再度、コンベア部を本体部に載架した時、受け部材と支持部材の位置合わせをする必要が無くなる。また、コンベア部を本体部に載架連結した時、前記ガイドのブレーキ機構は自動的に解除される為、ブレーキ操作は不要で、非常に便利である。
更に、請求項5記載の構成により、物品の底面が均一でないものでも、安定して幅寄せ搬送を行なうことが出来る。
また、請求項6記載の構成により、物品がガイドに当ると、ガイドが外側に向けて開く為、物品を転向させるモーメントが減少し、物品の転向を防止できる。そして、物品が当った際の衝撃を緩和することができるため、物品の損傷を防止できる。
更に、請求項7記載の構成により、駆動タイミングベルトの面圧調整が可能となり、ローラーの回転を最適な状態に調整できる。因って、搬送ローラーの安定した回転を確保できる。

BACKGROUND OF THE INVENTION
The present invention relates to a conveying device for conveying an article, and more particularly to a driving roller type conveying device.
[0002]
[Prior art]
A roller-type conveying device, a so-called roller conveyor, has rollers arranged in parallel at equal intervals to form a conveying surface.
For this reason, there is an advantage that there is no need for belt troubles due to meandering of belts and belt replacement due to belt wear, since a wide belt is not used as the conveyor surface of the belt conveyor. Since there is a gap between the rollers, the wrinkles of the conveyed product can easily enter the conveyor (in the frame), so cleaning must be performed regularly, but cleaning the conveyor is difficult. , There was a drawback.
[0003]
Therefore, if the conveyor portion is configured to be detachable from the main body portion, the conveyor portion is separated from the main body portion, and cleaning can be performed in such a state, the cleaning becomes easy.
[0004]
[Problems to be solved by the invention]
However, although it is necessary to drive each roller which comprises a conveyor part, when providing a drive source in a main-body part, there is no good method of transmitting a driving force to each roller of a removable conveyor part, and it has implement | achieved. There is no actual situation.
Further, when a roller conveyor is applied as an article transporting device to a labeling apparatus that attaches a label to an article, the position on the article to which the label is attached needs to be a preferable position. For that purpose, the width direction of the article There was no good drive mechanism for moving the guide that regulates the position of the lens.
[0005]
In addition, when a free roller is provided obliquely in the guide direction in order to keep the article along the guide, there is a problem that if the bottom surface of the article is not uniform, the width adjustment is not successful.

It is providing the conveying apparatus which can drive the roller of a conveyor part reliably.
Another object of the present invention is to provide a device that can freely move and adjust a guide disposed on the conveyor side in the width direction of the conveyance path.
Furthermore, another object is to provide a transport device that can reliably move in the width direction (width adjustment) even if the bottom surface of the article transported on the roller is not uniform. It is another object of the present invention to provide a transport device having a guide that does not change the direction of an article even if the manner of contact with the guide changes.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the technical means of the transport device according to the present invention includes: a main body portion in which an endlessly rotating drive timing belt is wound and arranged on the upper surface; and a transport roller is installed and held on the upper surface of the main body portion. Each of the transport rollers of the conveyor unit is attached with a passive pulley that meshes with the drive timing belt of the main body unit, and the conveyor unit is transported by the rotation of the drive timing belt. The roller is configured to be driven via a passive pulley.
Thereby, each roller of a conveyor part can be driven with the drive source of a main-body part, and since a main-body part and a conveyor part can be attached or detached separately, cleaning can be performed easily.
[0008]
The driving timing belt may be either a single-sided tooth timing belt in which teeth are formed only on one side of the outer peripheral surface or a double-sided tooth timing belt in which teeth are formed on both inner and outer peripheral surfaces. However, in the case of a single-sided toothed timing belt, it is necessary to provide a measure for preventing slipping, such as providing a roller for pressing the timing belt on a driving pulley around which the timing belt is wound.
When a double-sided tooth timing belt is used as the drive timing belt, the timing belt meshes with both the drive pulley installed on the main body and the passive pulley of the conveyor, and the main body is vertically compatible with the passive pulley of the conveyor. A support pulley is installed and supported at a position to be supported (claim 2). Thereby, the strong tension for rotating the drive timing belt itself can be eliminated. Moreover, even if surface pressure is applied to the timing belt by the passive pulley, the support pulley is arranged at the corresponding position of the main body, so that the tension of the timing belt does not change so much. There is little possibility that the timing belt will come off.
[0009]
In addition, a guide that regulates the position (width position) of the article in the transport path of the conveyor is provided in the conveyor portion of the transport device, and the guide is connected through a gap between the support member disposed below the transport roller and the roller. In addition, the support member is movable toward and away from a receiving member that is movable in the width direction provided in the main body. Thereby, the position of the guide arrange | positioned at the conveyor part side detachable with respect to a main-body part can be changed automatically.
[0010]
The guide is fixed to the conveyor portion by a brake mechanism when the conveyor portion is separated from the main body portion, and when the conveyor portion is mounted and connected to the main body portion, the brake mechanism comes into contact with the receiving member, and the brake mechanism Is released (Claim 4). Therefore, when the conveyor part is removed from the main body part, the guide position is fixed by the brake mechanism. Therefore, when the conveyor part is mounted on the main body part again, it is necessary to align the receiving member and the support member. Disappear. Further, when the conveyor portion is mounted on the main body, the brake mechanism of the guide is automatically released, so that the brake operation can be made unnecessary.
[0011]
Further, between the rollers arranged side by side in the conveyor section, a width-shifting roller that is rotatable in an oblique direction toward the guide, and a conveyance surface at the front side in the conveyance direction with respect to the width-shifting roller An irregularly shaped roller that changes up and down from the surface of the roller may be arranged so as to be freely rotatable. Examples of the deformed roller include a substantially rhombic section, an elliptical shape, a non-circular roller, and the like. In short, any shape having a difference in length from the rotation center to the outer peripheral surface may be used. Thereby, even when the bottom surface of the article to be conveyed is uneven and not uniform, the width can be reliably reduced.
Further, the guide may be formed to be inclined so as to expand toward the starting end side of the conveyor portion, and may be supported so as to be further movable in the expanding direction by contact of an article. In this case, when the article hits the guide, since the guide opens outward, the moment for turning the article is reduced, and the turning of the article can be prevented. Moreover, it acts to relieve the impact when the article hits.
[0012]
Further, the connecting portion between the main body portion and the conveyor portion is provided with a height changing means capable of changing the vertical distance between the two portions, and the surface pressure of the drive timing belt can be adjusted by adjusting the height changing means. (Claim 7). As a result, the surface pressure of the drive timing belt can be adjusted by adjusting the height changing means, and the rotation of the roller can be adjusted to an optimum state.
