Description

【0001】
【発明の属する技術分野】
本発明は、成形機により成形された成形品を型から受け取った後、搬送し取り出すための取出機及びその取出方法に係るものである。
【0002】
【従来の技術】
従来、成形品の取出機として、図10に示すように、成形機51の軸線に対し直角方向に延出する直角方向フレーム52を設けて成形品を直角方向に搬送し取り出すタイプ(例えば、特許文献1参照)が知られている。このタイプの取出機50は、成形機51の軸線に対し平行方向に延出する平行方向フレーム53を併せ持っており、平行方向フレーム53は、直角方向フレーム52に摺動可能に係合することで直角方向フレーム52に沿って走行可能となっている。この平行方向フレーム53には、ロッド上下動装置56が摺動可能に係合しており、ロッド上下動装置56は、その先端に設けられたチャック57とともに平行方向フレーム53に沿って走行可能となっている。この平行方向フレーム53に沿ったロッド上下動装置56の走行は、成形機51の開いた可動型54と固定型55の間にロッド上下動装置56がチャック57を下動させた後、主としてチャック57が成形品を受け取るために可動型54に向かって平行方向に移動したり、チャック57が成形品を受け取り可動型54と固定型55との略中間まで平行方向に移動したりするために行われる。そのため、平行方向フレーム53は直行方向フレーム52から可動型54の略上部まで延出されており、直角方向フレーム52と比べて長さが短い。
また、別の取出機として、成形機の軸線に対し平行方向に成形品を搬送して取り出すための長い平行方向フレームのみを設けて成形品を平行方向に搬送して取り出すタイプ(例えば、特許文献2、特許文献3、特許文献4参照。)も知られている。

【発明が解決しようとする課題】
前者の直角方向に搬送し取り出すタイプでも、後者の平行方向に搬送し取り出すタイプでも、当然、取り出し位置はそれぞれの搬送方向上の一箇所にしかない。このように、取り出し位置が一箇所にしかなくても、その取り出し位置に同一の成形品を多数取り出し続けている場合には、次に述べるような問題は生じない。
しかし、成形機では同一の成形品を所定数成形した後に別の成形品の成形に切り替えることが普通であり、その切替時には取出機においても前記取り出し位置における取り出し及び回収のための段取りを替える必要がある。その際に、前記のとおり取り出し位置が一箇所にしかないと、前の成形品の取り出しが終了するまで、その取り出し位置が占有されるので、その取り出し位置で次の成形品の取り出しのための段取りの準備にとりかかることができない。このため、成形機の稼動効率が上がらない原因となっていた。
そこで、この段取りを替える時間を節約しようとして、複数の取出機を交代で使用することも考えられるが、そうすると稼動していない取出機が交互に生じて工場の床面を無駄に占有するという問題がある。
また、従来の直角方向フレームを設けたタイプの取出機が併せ持つ平行方向フレームを成形機の平行方向の先方へ延長して、成形機の平行方向にも成形品を搬送して取り出せるようにすることも考えられるが、延長して重量が増した平行方向フレームを直角方向に繰り返し高速駆動するために大きな駆動力が必要となるので、その延長の実現は困難である。また、前記高速駆動時に、延長した平行方向フレームの先端に駆動遅れが生じて、平行方向フレームに長さ方向の歪みが生じやすくなるという問題も生ずる。
【0005】
本発明の目的は、上記課題を解決し、直角方向に成形品を搬送して取り出すタイプの取出機が併せ持っている平行方向フレームを延長せずに、成形機の平行方向にも成形品を搬送して取り出すことができるようにすることで、効率的に異なった成形品を取り出し及び回収する段取りに替えることができ、工場の床面の利用効率を高めることができる成形品の取出機及びその取出方法を提供することにある。
【0006】
【課題を解決するための手段】
上記課題を解決するために、本発明の成形品の取出機は、成形機の軸線に対し直角方向に延出する直角方向フレームに、成形機の軸線に対し平行方向に延出する平行方向フレームを直角方向に走行可能に設け、平行方向フレームに走行体を平行方向に走行可能に設け、走行体にロッドが下動した後に上動するロッド上下動装置を取着し、ロッドの下端部に成形機から成形品を受け取るチャックを設け、成形品を成形機から主として直角方向フレームに沿って前記直角方向に搬送し取り出す成形品の取出機において、走行体とロッド上下動装置との間にロッド上下動装置を上下方向と平行方向とが作る面内で回転させる回転機構を設け、走行体が平行方向フレームの端部又はその近傍にまで走行したときに、ロッド上下動装置を回転機構により回転させて、下動したロッドの下端部のチャックを平行方向フレームの端部よりも平行方向の先方に位置させ、もって成形品を成形機から主として平行方向フレームに沿って平行方向にも搬送し取り出せるようにしたとともに、ロッドの下端部とチャックとの間にチャックを上下方向と平行方向とが作る第二面内で回転させる第二回転機構を設けたことを特徴とする。
【0007】
ロッドの下端部にチャックをどのように設けるかは、特に限定されないが、前記のとおりロッドの下端部とチャックとの間にチャックを上下方向と平行方向とが作る第二面内で回転させる第二回転機構を設けることにより、チャクが成形品を受け取る際、成形品を搬送する際及び成形品を解放する際それぞれのチャックの向きを最適な方向にすることができる。
【0008】
本発明の成形品の取出方法は、成形機の軸線に対し直角方向に延出する直角方向フレームに、成形機の軸線に対し平行方向に延出する平行方向フレームを直角方向に走行可能に設け、平行方向フレームに走行体を平行方向に走行可能に設け、走行体にロッドが下動した後に上動するロッド上下動装置を取着し、ロッドの下端部に成形機から成形品を受け取るチャックを設け、成形品を成形機から主として直角方向フレームに沿って直角方向に搬送し取り出す成形品の取出機において、走行体とロッド上下動装置との間にロッド上下動装置を上下方向と平行方向とが作る面内で回転させる回転機構を設け、走行体が平行方向フレームの端部又はその近傍にまで走行してから、ロッド上下動装置が回転機構により回転し、下動したロッドの下端部の前記チャックが平行方向フレームの端部よりも平行方向の先方に位置し、もって成形品を成形機から主として平行方向フレームに沿って平行方向にも搬送し取り出すとともに、ロッドの下端部とチャックとの間にチャックを上下方向と平行方向とが作る第二面内で回転させる第二回転機構を設け、該第二回転機構により、チャックが成形品を受け取る際、成形品を搬送する際及び成形品を解放する際それぞれのチャックの向きを最適な方向にすることを特徴とする。
【0009】
上記手段において、ロッド上下動装置によるロッドの下動はロッドの下端部がロッド上下動装置から離れる動きを指し、また、ロッドの上動はロッドの下端部がロッド上下動装置に近づく動きを指す。「チャック」は、成形品を成形機から受け取ることができれば、どのような態様の装置でもよく、成形品を把持する把持装置や成形品を吸着する吸着装置を例示できる。
回転機構の回転角度は、ロッド上下動装置が垂立した状態を0°とし、チャックを平行方向フレームの端部よりも平行方向の先方に位置させる回転の向きを正とすると、回転角度が15°より小さいと回転によるロッドの上下動の長さの変位を十分に生かすことができず、チャックを平行方向フレームの端部よりも僅かに平行方向の先方に位置させるだけであり、回転角度が75°より大きいと回転したロッド上下動装置及びロッドに対して横方向に加わる荷重が大きいため、特に限定されないが、15°〜75°が好ましく、30°〜45°がさらに好ましい角度範囲となる。
第二回転機構の回転角度は、チャックが平行方向フレームの端部に向かってチャックが向いている状態を0°とし、チャックがロッドの下方を向いてから平行方向フレームの端部と逆(180°)にチャックが向くように、チャックを回転する向きを正とすると、特に限定されないが、105°〜165°が好ましく、120°〜135°がさらに好ましい。その回転角度は、回転機構の回転角度と、成形品を解放する向きにあわせて設定する。
【0010】
【発明の実施の形態】
以下、本発明を射出成形機用の成形品の取出機に具体化した実施形態について図1〜図8を参照して説明する。射出成形機30は、可動型31及び固定型32とからなり、説明の都合上、射出成形機30の可動型31及び固定型32の取付面を上下方向とし、型開閉方向を射出成形機30の軸線に対し平行方向とし、型開閉方向に対して直角方向を射出成形機30の軸線に対し直角方向とする。
【0011】
取出機10は、直角方向フレーム11、平行方向フレーム12、走行体13、ロッド上下動装置14、ロッド15、チャックとしての吸着装置16で主に構成されている。
【0012】
直角方向フレーム11は、射出成形機30の固定盤33上に取り付けられ、射出成形機30の軸線に対し直角方向であって、射出成形機30の一方の側面に延出し、その上面には直角方向レール18が直角方向フレーム11と平行に延びるように取付けられている。直角方向レール18には、直角方向レール18に摺動可能に係合することで、直角方向レール18に沿って直角方向に走行可能な平行方向フレーム支持体19が設けられている。
【0013】
平行方向フレーム支持体19は、内蔵された駆動装置(図示略)により直角方向レール18の任意の位置へ走行させられるようになっている。平行方向フレーム支持体19には、射出成形機30の軸線に対し平行方向であって、直角方向フレーム11より可動型31及び固定型32方向に延出するとともに、平行方向フレーム支持体19と共に直角方向フレーム11に設けられた直角方向レール18に沿って直角方向に走行する平行方向フレーム12が支持されている。
平行方向フレーム12の一方の側面には、平行方向レール20が平行方向フレーム12と平行に延びるように取付けられている。また、平行方向レール20には、平行方向レール20に摺動可能に係合することで、平行方向レール20に沿って射出成形機30の軸線に対し平行方向に走行する走行体13が設けられている。走行体13は、平行方向フレーム支持体19と同様に内蔵された駆動装置(図示略)により平行方向レール20の任意の位置へ走行させられる。
【0014】
走行体13には、走行体13と走行体13に取着されたロッド上下動装置14との間に、ロッド上下動装置14を上下方向と平行方向とが作る面内で回転させる回転機構25が設けられている。回転機構25は、下記するロッド15が下方となって垂立した状態を0°とし、ロッド15の下端部15aに設けられている下記する吸着装置16を平行方向の先方に、75°未満の範囲内で駆動装置(図示略)により設定した回転角度に回転させる。
【0015】
また、ロッド上下動装置14は、角棒状のロッド15をその長さ方向に摺動可能に支持しており、駆動装置(図示略)を駆動させることにより、ロッド15がその長さ方向で下動した後に上動する。
ロッド15の下端部15aには、射出成形機30から成形品1を受け取り吸着する吸着装置16が、その裏面側にロッド15の下端部15aを成形機の軸線に対し直角方向から挟むように延びて形成されたフォーク16aによって、回転可能に取り付けられている。この吸着装置16の回転は、ロッド上下動装置14の回転機構25による回転の面と平行の第二面内で回転させる第二回転機構26により行われる。第二回転機構26は、吸着装置16が、ロッド15の下端部15aを中心として、ロッド15の下端部15aに内蔵された駆動装置(図示略)により、吸着装置16が、平行方向の先方を向いた状態となる復帰位置と下方を向く方向に回転した回転位置との間で、165°の範囲で設定した回転角度に回転させる。
【0016】
吸着装置16は、その表面側に成形品1を吸着する吸着面16bを備え、吸着面16bには、複数の(図示例では4つの)吸着パッド17が、吸着面16bと吸着パッド17の吸着表面とが平行になるように取り付けられている。この吸着パッド17は射出成形機30から成形品1を吸着して取り出すもので、図示しない真空ポンプ又は真空発生装置等(図示略)にエアチューブ等を介して接続されており、真空発生装置と吸着パッド17との間の弁が、開状態であると吸着パッド17は成形品1を吸着できるように真空圧になり、開状態から閉状態にし、吸着装置16の配管内を大気開放にすると、成形品1を吸着できるだけの真空圧を保てず成形品1を解放する。なお、吸着パッド17は、アクチュエータ(エアシリンダ、サーボモータ、リニヤモータ、電磁ソレノイド等を例示できる。)により駆動されるチャック等に変更してもよい。
【0017】
また、射出成形機30の上部には、成形品回収手段としてのベルトコンベア40が設けられている。ベルトコンベア40は、載せられた成形品1を、射出成形機30の平行方向の先方に移動するようになっている。なお、ベルトコンベア40の代わりに他の搬送装置や回収箱を設置してもよい。
【0018】
取出機を用いる際の成形品回収手段として特に成形機の上部にベルトコンベアを用いることについて述べる。本実施形態と類似のフレーム構成である従来の直角方向フレーム52と成形品を受け取るための短い平行方向フレーム53とを設けて直角方向に成形品を搬送して取り出すタイプの取出機50では、成形品は、直角方向しか取り出すことができなかったので、直角方向の対応する場所に成形品回収手段(容器等)を設置しており、成形機51の上部に成形品回収手段としてのベルトコンベアを設けることはない。本実施形態とは異なるフレーム構成である従来の平行方向に成形品を搬送して取り出すための長い平行方向フレームのみを設けて成形品を平行方向に搬送して取り出すタイプの取出機では、平行フレームの長さが成形機の端部まである場合は、成形品は平行フレームに沿って搬送されることで成形機の外側まで取り出すことができ、成形品回収手段を成形機の外側に設けていた。また、平行フレームの長さが成形機の途中部までしかなかった場合は、平行フレームの先端付近に成形品回収手段として、平行フレームの先端付近から成形機の端部まで延びるベルトコンベアを設けて、成形品をベルトコンベアに搬送させて成形機の外側まで取り出したり、回収容器を設けて、成形品を回収容器ごと成形機の外側まで取り出したりすることができた。平行フレームの長さが成形機の端部まで足りない場合に用いられているベルトコンベアは、その平行フレームの長さを補うものとして作用していた。
【0019】
上記構成の取出機10による成形品1を平行方向フレーム12に沿って平行方向に搬送し取り出す作業に続いて、成形品2の直角方向フレーム11に沿って直行方向に搬送して取り出す作業を行う場合について説明する。
【0020】
図3〜図5に示すように、射出成形機30の軸線に対し平行方向へ成形品1を取り出す作業を行う場合、射出成形機30の成形動作中は、吸着装置16は、可動型31及び固定型32より上方の取出待機位置Oであって吸着面16bが平行方向の先方を向いた復帰位置で待機している。射出成形機30が1ショットを終了し、型開き後に取出開始指令が出ると、まず、▲1▼ロッド15が下動して、吸着装置16が開いた可動型31と固定型32との間に下降し、吸着面16bは成形品1がある可動型31と対面する。▲2▼走行体13が型に向かって前進し、▲3▼吸着パッド17が成形品1を吸着して受け取る。次に、▲4▼走行体13が型より後退し、▲5▼ロッド15が上動して、吸着装置16が型より上方の位置である取出待機位置O近傍まで上昇し、取出機10が射出成形機30に型閉め開始指令を出力する。
続いて、▲6▼走行体13が平行方向フレーム12の端部まで走行し、▲7▼吸着装置16が第二回転機構26により回転して吸着面16bの向きをあらかじめ指定した回転角度(135°)の回転位置に変え、▲8▼回転機構25によりロッド上下動装置14をあらかじめ指定した回転角度(45°)に回転する。これにより、吸着面16bは真下を向く。その後、▲9▼ロッド15が下動し、吸着装置16が先方に下降して、吸着装置16が平行方向フレーム12の端部よりも平行方向の先方に位置する。吸着装置16に吸着されている成形品1はベルトコンベア40の上方近傍に位置している。(10)吸着パッド17が成形品1をベルトコンベア40上に解放する。その後、(11)ロッド15が上動して吸着装置16が上昇して、(12)ロッド上下動装置14が回転機構25により垂立状態まで回転し、(13)吸着装置16が第二回転機構26により復帰位置まで回転して、(14)走行体13が後退して、吸着装置16が取出待機位置Oに復帰する。
【0021】
上記の射出成形機30の軸線に対し平行方向への成形品1の搬送し取り出す作業を繰り返し行っている間に、作業者は射出成形機30の軸線に対し直角方向へ別の成形品2を搬送し取り出す作業の準備を行う。即ち、射出成形機30の側面の左右方向(例えば右側)に成形品2の回収箱又は可動式のコンベア等を用意しておく。
【0022】
次に、図6〜図8に示すように、射出成形機30の軸線に対し直角方向へ成形品2を搬送し取り出す作業を行う場合、上記(1)〜(5)までの工程が同様に進み、続いて、(6)’平行方向フレーム支持体19が取出機10の側面の右方向に走行し、成形品回収容器41の上方で停止し、(7)’吸着装置16があらかじめ設定した回転角度(90°)に回転して、吸着面16bが下方向きに変わり、(8)’ロッド15が下動し、吸着装置16が下降し、(9)’吸着パッド17が成形品2を成形品回収容器41に解放する。その後、(10)’ロッド15が上動し、吸着装置16が上方に移動し、(11)’吸着装置16が復帰位置まで回転し、(12)’平行方向フレーム支持体19が取出機10へ接近方向に走行して、吸着パッド17が取出待機位置Oに復帰する。
【0023】
上記の射出成形機30の軸線に対し直角方向への成形品2の搬送し取り出す作業を繰り返し行っている間に、作業者は射出成形機30の軸線に対し平行方向へ次の射出成形によって成形される別の成形品を搬送し取り出す作業の準備を行う。即ち、ベルトコンベア40上に残された成形品1の回収やベルトコンベア40のメンテナンス等を行うことができる。
【0024】
従って、本実施形態の取出機10によれば、以下のような(1)〜(5)のような効果が得られる。
(1) 直角方向フレーム11と成形品1を受け取るための長さを備えた平行方向フレーム12とを設けて直角方向に成形品1を搬送して取り出すタイプの取出機10であっても、回転機構25によりロッド上下動装置14をあらかじめ指定した回転角度に回転することで、下動したロッド15の下端部の吸着装置16が平行方向フレーム12の端部よりも平行方向の先方に位置することができる。それにより、吸着装置16に吸着された成形品1を平行方向フレーム12の端部よりも平行方向の先方に搬送して取り出すことができる。
(2) また、回転機構25によるロッド上下動装置14が回転する回転角度を変更することで、成形品1を平行方向に取り出す際の平行方向の取り出し位置を調整することができる。
(3) 回転機構25によりロッド上下動装置14をあらかじめ指定した回転角度に回転することで、成形品回収手段がベルトコンベア40である場合には、吸着装置16を平行方向フレーム12の端部より先方に位置することができるので、平行方向の長さが短いベルトコンベア40を使用することができる。
(4) 成形品を射出成形機30の軸線に対し平行方向にも搬送して取り出すことができるので、射出成形機30の平行方向へ搬送し取り出す作業と、射出成形機30の直角方向へ搬送し取り出す作業とを交互に行うことで、射出成形機30の稼動中にも異なった成形品の取り出し及び回収のための段取りを行うことができるので、段取りを替える作業の効率化を図ることができる。また、段取りを替えるために休止させる射出成形機30が生じず、常に射出成形機30が稼動することになるので、工場の床面の利用効率を高めることができる。
(5) 第二回転機構26により吸着装置16を回転できるようにすることで、吸着装置16の吸着面16bを、成形品1、2を受け取る射出成形機30の可動型31と対面する向きにしたり、成形品1を平行方向に搬送して取り出す際に、ロッド上下動装置14がどのような回転角度で回転しても、ベルトコンベア40の上面と対面する向きにしたり、成形品1を直角方向に搬送して取り出す際に、真下の成形品回収容器41の開口と対面する向きにしたりすることが、回転角度の設定によって自在にできる。
【0025】
なお、本発明は前記実施形態に限定されるものではなく、例えば以下のように、発明の趣旨から逸脱しない範囲で適宜変更して具体化することもできる。
(1)図9に示すように、回転機構25によるロッド上下動装置14の回転角度やロッド15の下動する長さを調節したり、射出成形機30の形状によっては、吸着装置16に吸着された成形品1を射出成形機30の端部より先方の成形品回収容器42まで搬送して取り出すことができるようにすること。
(2)成形品を取り出した後、まず、射出成形機の軸線に対し直角方向へ成形品を搬送し、引き続き軸線に対し平行方向に成形品を搬送し、ロッド上下動装置を回転させてから成形品を解放し取り出すこと。
(3)成形品を受け取った吸着装置が成形品回収手段まで成形品を搬送する前に、ゲートカット装置の向きにあわせて、ロッド上下動装置を回転させたり、吸着装置を回転させたりして、ゲートカット処理をすること。
(4)回転機構によるロッド上下動装置の回転と第二回転機構によるチャックの回転とは、どちらが先に行われてもよいし、同時に行われてもよい。
【0026】
【発明の効果】
以上詳述した通り、直角方向に成形品を搬送して取り出すタイプの取出機が併せ持っている平行方向フレームを延長せずに、成形機の平行方向にも成形品を搬送して取り出すことができるようにすることで、効率的に異なった成形品を取り出し及び回収する段取りに替えることができ、工場の床面の利用効率を高めることができる。また、第二回転機構により、チャックの向きを最適な方向にすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a take-out machine and a take-out method for conveying and taking out a molded product molded by a molding machine from a mold.
[0002]
[Prior art]
Conventionally, as a molded product take-out machine, as shown in FIG. 10, a right-angle frame 52 extending in a direction perpendicular to the axis of the molding machine 51 is provided, and the molded product is conveyed and taken out in a right-angle direction (for example, a patent Document 1) is known. This type of take-out machine 50 also has a parallel frame 53 extending in a direction parallel to the axis of the molding machine 51, and the parallel frame 53 is slidably engaged with the right-angle frame 52. The vehicle can travel along the right-angled frame 52. The parallel frame 53, and the rod vertically moving device 56 is slidably engaged with the rod vertically moving device 56, and can travel along a direction parallel frame 53 together with the chuck 57 provided on the distal end It has become. The rod vertical movement device 56 travels along the parallel frame 53 mainly after the rod vertical movement device 56 moves down the chuck 57 between the open movable mold 54 and the fixed mold 55 of the molding machine 51. 57 is moved in the parallel direction toward the movable mold 54 to receive the molded product, and the chuck 57 is moved in the parallel direction to receive the molded product and move substantially in the middle between the movable mold 54 and the fixed mold 55. Is called. Therefore, the parallel direction frame 53 extends from the orthogonal direction frame 52 to substantially the upper part of the movable die 54 and is shorter than the right direction frame 52.
In addition, as another take-out machine, a type in which only a long parallel frame for conveying and taking out a molded product in a direction parallel to the axis of the molding machine is provided and the molded product is taken out in a parallel direction (for example, patent document) 2, Patent Document 3 and Patent Document 4) are also known.

[Problems to be solved by the invention]
Of course, both the former type that is conveyed and taken out in the right-angle direction and the latter type that is carried and taken out in the parallel direction, there is naturally only one takeout position in each conveying direction. As described above, even when there is only one take-out position, the following problems do not occur when a large number of the same molded product is continuously taken out at the take-out position.
However, in a molding machine, it is normal to switch to molding of another molded product after molding a predetermined number of the same molded product, and at the time of switching, it is necessary to change the setup for taking out and collecting at the takeout position in the takeout machine. There is. At that time, if there is only one take-out position as described above, the take-out position is occupied until the previous take-out of the molded product is completed. Can't get ready for. For this reason, the operating efficiency of the molding machine has not been increased.

Rotating to the rotation angle (90 °), the suction surface 16b changes downward, (8) 'rod 15 moves downward, suction device 16 descends, (9)' suction pad 17 removes molded product 2 The molded product collection container 41 is released. Thereafter, (10) 'rod 15 moves up, suction device 16 moves upward, (11)' suction device 16 rotates to the return position, and (12) 'parallel frame support 19 is unloader 10. The suction pad 17 returns to the take-out standby position O.
[0023]
While the operation of transporting and taking out the molded product 2 in the direction perpendicular to the axis of the injection molding machine 30 is repeated, the operator performs molding by the next injection molding in the direction parallel to the axis of the injection molding machine 30. Prepare for the work of transporting and taking out another molded product.
