Description

【０００１】
【発明の属する技術分野】
本発明は成形品処理装置に関し、セメントモルタル、セラミック等の製品を製造する場合に、成形機により成形される成形品を加熱、加湿して養生を行ったり、生ゴミ等を圧縮したり、魚油を圧搾した後の魚の搾りかすを加熱乾燥する等の後処理を効率的に行うものである。
【０００２】
【従来の技術】
従来、例えばセメントモルタル製品、セラミック製品を製造する際に、モルタルなどの原料に振動を加えながら加圧成形する成形機等によって成形された成形品を養生するための後処理は、この成形品を処理室に搬入することにより行われていた。
しかしながら、成形機により成形された成形品を処理室に搬入したり後処理済みの製品をこの処理室から搬出するには人手と時間とを要していたばかりでなく、この未養生の成形品は振動や衝撃により崩れ易く、亀裂などを生じ易いことからその取扱は困難であった。
かかる点から、出願人は、例えば成形機により成形される成形品を処理室内に設ける移動自在な多列・多段の収納棚に自動的に搬入し、また、この搬入と同時に処理済みの成形品を自動的に搬出するようにした成形品処理装置として例えば特願平２−７５４６９号として出願し、権利化するのに至っている。
この出願の発明にかかる成形品処理装置の概略を図１２ないし図１４によって説明する。
この成形品処理装置は、成形機ａにより成形された成形品ｂをそれぞれパレットｃに載置した状態で収納するための多段・多列に配列された棚を備える移動可能な収納棚ｄと、この収納棚ｄを包囲する処理室ｅと、成形機ａにより成形された成形品ｂをそれぞれ収納棚ｄに搬入するために処理室ｅの側面に設けた搬入ステーションｆと、処理室ｅでの処理をし終えた製品を収納棚ｄに対して成形品ｂの搬入と同時に搬出するために処理室ｅの側面に近接して設けた搬出ステーションｇと、搬入ステーションｆによる成形品ｂの搬入位置Ｉ′に成形品ｂが通過可能な開口部ｋに対応する大きさの複数の扉構成板ｉ１,ｉ２,ｉ３・・・を有する開閉手段ｈを、また搬出ステーションｇによる成形品ｂの搬出位置Ｏ′に少なくとも後処理済みの成形品ｂが通過可能な開口部ｋに対応する大きさの複数の扉構成板ｉ１,ｉ２,ｉ３・・・を有する開閉手段ｈ′を処理室ｅの壁面に設けた。lは成形品取り出し部である。
そして、成形機ａにより成形された成形品ｂの処理を行うために、成形品ｂの搬入位置Ｉ′に設けた開閉手段ｈの扉構成板ｉ１,ｉ２,ｉ３・・・を開閉して成形品ｂが通過可能な大きさに形成される開口部ｋから処理室ｅ内に備えた収納棚ｄの多段・多列に配列した棚に処理室ｅの側面に設けた搬入ステーションｆにより成形品ｂを搬入し、成形品ｂの搬出位置Ｏ′に設けた開閉手段ｈ′の扉構成板ｉ１,ｉ２,ｉ３・・・を開閉することにより成形品ｂが通過可能な大きさに形成される開口部ｋを通じて処理室ｅによる後処理済みの成形品ｂを収納棚ｄの棚から処理室ｅの側面に設けた搬出ステーションｇから搬出するものである。
このように、成形品ｂの搬入位置Ｉ′および搬出位置Ｏ′に設けた開閉手段ｈ,ｈ′の扉構成板ｉ１,ｉ２,ｉ３・・・を開閉して成形品ｂが通過可能な大きさに形成される開口部ｋを通じて処理室ｅ内に備える収納棚ｄの棚に対して成形品ｂの搬入と搬出とを行うものなので、成形品ｂおよび製品の搬入と搬出の際に、処理室ｅ内の後処理のための雰囲気が実質上変化することなく、燃料や材料を有効利用してエネルギーや資源の有効活用をはかろうとするものであった。また、搬入ステーションｆと搬出ステーションｇとを処理室ｅを挟んで対向して設け、成形品ｂの搬入と搬出とを同時に行うことにより、例えば成形品ｂの搬入数と後処理済みの成形品ｂ、すなわち製品の搬出数を同数にすることにより収納棚ｄに空きを生ずることなく、処理室ｅ内の成形品ｂと製品との合計数を処理室ｅに収納可能な最大の数に保つようにしたものである。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来の成形品処理装置は、処理室ｅ内に多段・多列の収納棚ｄを備え、この収納棚ｄに対して成形品ｂを搬入ステーションｆと搬出ステーションｇとにより搬入または搬出する構造なので、搬入と搬出とにはその分、時間と手間を要することになっていた。また、収納棚ｄの１つの棚に対する成形品ｂの搬入数と搬出数が限られるため、成形品ｂの後処理数を飛躍的に増加できず、増加するためには収納棚ｄの棚数を増し、大型化しなければならないので、処理室ｅ自体も大型化することになる。また、収納棚ｄの棚に収納する成形品ｂの大きさも制約を受けるので、大型の成形品ｂを処理するのには不向きであった。また、成形品ｂを処理室ｅに対して搬入したり、搬出するための開閉手段ｈ,ｈ′は、昇降用のシリンダsの駆動により駆動される多数の扉構成板ｉ１,ｉ２,ｉ３・・・を開閉することにより成形品ｂが通過可能な大きさの開口部ｋを形成することにより行われるため、成形品ｂの搬入と搬出とには絶え間なく頻繁に扉構成板ｉ１,ｉ２,ｉ３・・・を開閉しなければならず、その分の時間と手間、さらには扉開閉板ｉ１,ｉ２,ｉ３・・・を開閉するための昇降用シリンダsに圧力を送るポンプを駆動するために多大の電力等を要する。しかも、開閉手段ｈ,ｈ′自体、構造が複雑化し、多くの部品を必要とするから、製作、組立が容易には行えなかった。
【０００４】
本発明は上記従来の問題点を解決し、成形品の搬入と搬出とがパレットを積み重ねるようにして一度に多量に行え、成形品の後処理が処理室自体、大型化しなくても飛躍的に効率化し、また、大型の成形品を処理するのに適し、さらには成形品処理装置自体の構造が簡素化し、製作、組立も容易であり、製造コスト並びに設備費も安価な成形品処理装置を提供するものである。
【０００５】

【０００８】
また、本発明の請求項２に記載の発明は、請求項１において、前記搬入・搬出手段は、水平な前記案内軌条部を上方に設ける略門形の前記架台フレームと、前記案内軌条部に沿って回転可能な複数対の車輪が装設され、水平方向に前記搬入位置と前記搬出位置との間を移動可能なベース体と、該ベース体に付設される駆動源の駆動力により前記架台フレームの上面を基準面として垂直方向に昇降可能に設けられる昇降板と、該昇降板の両側に対向して開閉可能に設けられる前記挟持部材としての爪部材とから形成されることを特徴とする。
【０００９】
また、本発明の請求項３に記載の発明は、請求項１または２において、前記処理室は、長手方向の一端に、前記搬入位置および前記搬出位置に臨んで設けられる前記開口と、該開口の全部または大部分を占める大きさに形成され、前記開口に対し上下方向に開閉可能に設けられる戸板、および該戸板に一端が連結されるワイヤーを巻取ドラムに捲回するモータよりなる前記開閉手段と、内部に設けられる移送手段よりなる所望数の往路と復路とにより形成されることを特徴とする。

【００１１】
【発明の実施の形態】
以下、図面に従って本発明を製品としてセメントモルタル製品を成形する場合を一実施形態として説明する。
図１は本発明の成形品処理装置の一実施形態を示す平面図、図２は同じく本実施形態を構成する移送手段の一例を示す斜視図、図３は同じく本実施形態を構成する移送手段の他例を示す斜視図、図４は同じく本実施形態を構成する搬入・搬出手段の一例を示す正面図、図５は同じく本実施形態を構成する搬入・搬出手段の一例を示す斜視図、図６は同じく本実施形態を構成する搬入・搬出手段における挟持部材の開閉機構部を示す拡大正面図、図７は同じく挟持部材の開閉機構部を示す拡大平面図、図８は同じく本実施形態を構成する開閉手段および予備開閉手段の一例を示す斜視図、図９は同じく本実施形態を構成するパレットの一例を示す拡大平面図、図１０は同じくパレットの一例を示す拡大側面図、図１１は同じくパレットの積み重ね状態を示す拡大断面図である。
【００１２】
図９ないし図１１において１は成形機２により成形した成形品３を後処理するために載置され、移送したり、保管に供するために使用されるパレットであり、このパレット１は所望数が積み重ね可能である。
また、このパレット１は、例えば図示するように剛性材により形成され、成形品３が載置されるパレット本体１Ａの周囲に積み重ね可能に外回り縁材４が設けられ、該外回り縁材４の上面または下面の一面に位置決め手段５を所望数設けるとともに外回り縁材４の上面または下面の対応する他面には上段または下段に配置される位置決め手段５の先端部６を受け入れる凹面部７を設ける。
【００１３】
前記位置決め手段５は位置決めピン８であり、該位置決めピン８は、長さＬを外回り縁材４の厚みＴよりも長い丈に形成することにより積み重ねられる上段および下段のパレット本体１Ａは相互に搬入・搬出手段１１の１対の挟持部材１２Ａ,１２Ａ；１２Ｂ,１２Ｂが係脱可能になり、収容空間部９に連通される空隙１０が形成される。
【００１４】
前記成形機２は例えば図には示さないが、上型と、下型と、下型の周囲に昇降可能に設けられる型枠とにより形成される加圧成形機が用いられる。
また、前記成形品３は、本実施形態のようにセメントモルタル製品のほか、例えばセラミック等の製品、さらには、圧縮、乾燥処理する場合の生ゴミ、魚油を圧搾する場合の魚の搾りかす等があげられる。
【００１５】
図１、図２、図３において１３は成形機２により成形される成形品３を、パレット１を介して型崩れすることなく、保形性を維持しながら搬入・搬出手段１１に移送するための移送手段としてのコンベアである。このコンベア１３は、例えば図２に示すように、駆動源としてのモータＭと、該モータＭの駆動力を受動して回転可能な１つを上流側に含む所望複数のスプロケット１４と、該スプロケット１４の外周に巻回され台車１５が移動可能にコロ１６を装設した多数のチェーン素子１７ａを連結したチェーン１７等の動力伝達部品とにより形成されるが、コンベア１３は図２、図３に示すものは好適例を示すものであり、これに限らず、例えばローラコンベア、ベルトコンベアであってもよい。
【００１６】
Ｓ１，Ｓ２は成形品３がパレット１を介してコンベア１３により搬入・搬出手段１１に所望個数移送されて来たか否かを検知するためのセンサーであり、このセンサーＳ１，Ｓ２はコンベア１３の傍らに所定の間隔Ｋ１をあけて配置される。
そして、センサーＳ１，Ｓ２がコンベア１３により搬入・搬出手段１１に移送されて来る成形品３の該当個数を検知すると、ストッパ１８がコンベア１３に突出することによりコンベア１３により移送されて来る後続の成形品３から分離される。図示する実施形態では、３個毎に１ブロックを形成して搬入・搬出手段１１に供給されるようになっている。
【００１７】
前記搬入・搬出手段１１は、図４、図５において積み重ねられるパレット１を所望数段毎に挟持部材１２Ａ,１２Ａ；１２Ｂ,１２Ｂにて挟持して吊り上げ、上昇、移送、降下させる一連の動作を行うためのものであり、水平な案内軌条部１９を上方に設ける略門形の架台フレームＦと、該案内軌条部１９に沿って回転可能な複数対の車輪２０が装設された水平方向Ｙに搬入位置Ｉと搬出位置Ｏとの間を移動可能な共用のベース体２１と、該ベース体２１に付設される駆動源２２の駆動力により前記架台フレームＦの上面を基準面として垂直方向Ｘに昇降可能に設けられる左右に配置された２個の昇降板２３,２３と、該昇降板２３,２３の本体ケース２３Ａの両側に対向して開閉可能に設けられる１対の挟持部材１２Ａ, １２Ａ,；１２Ｂ,１２Ｂとしての爪部材２４,２４；２４,２４とから形成される。前記駆動源２２としては、例えば図示する本実施形態ではシリンダ・ロッド２２Ｂが伸縮するシリンダ２２Ａが用いられるが、これに限ることなく、駆動源としてサーボモータを用いるとともにボール・スクリューを用いてサーボモータの回転を受動して回転され、回転運動を直線運動に変換することにより昇降板２３を昇降可能に設けてもよい。
【００１８】
ベース体２１を水平方向Ｙに移動するための移動手段としては、図４および図５に図示する実施形態では例えばモータＭ１の駆動力を、モータシャフトに装設したピニオン２５と、該ピニオン２５に歯合され、前記車輪２０と同軸に設けたピニオン２６と、該ピニオン２６が歯合され、案内軌条部１９に沿って敷設されたラック２７とから形成される。そして、モータＭ１を駆動することによりモータシャフトに装設したピニオン２５を回転すると、該ピニオン２５に歯合されるピニオン２６はラック２７に歯合されながら回転されるので、ベース体２１は車輪２０が回転されて案内軌条部１９に沿って架台フレームＦ上を所望位置に往復移動するようになっている。
上記説明では、ベース体２１を水平方向Ｙに移動するための移動手段としてピニオン２５,２６と、ラック２７とを動力伝達部品に用いているが、これに限ることなく例えばスプロケットおよびチェーンとを動力伝達部品に用いて車輪２０に伝達することにより案内軌条部１９に沿ってベース体２１を架台フレームＦ上の所望位置に往復移動にすることもできる。
【００１９】
また、前記爪部材２４の開閉機構としては、駆動源としてのシリンダ２２Ａのシリンダ・ロッド２２Ｂの伸縮動作により案内棒２８,２８に案内されて昇降可能になる前記昇降板２３の本体ケース２３Ａの左右に軸２９により爪部材２４の中間部が枢着され、基端部が軸３０にてシリンダ３１のロッド３１Ａの先端に枢着することにより左右１対の爪部材２４,２４はシリンダ３１の駆動により開閉される。
【００２０】
図１において３２は処理室であり、この処理室３２は搬入・搬出手段１１により成形品３がパレット１毎所望数段、搬入・搬出されるように搬入位置Ｉ、および搬出位置Ｏに開閉可能に設けられる開閉手段３３、並びに処理を行う成形品３、および処理後の成形品３をパレット１毎に移送する移送手段３４を内部に設けている。
また、前記処理室３２は、長手方向の一端３２ａに搬入位置Ｉおよび搬出位置Ｏに臨んで設けられる開口３５ａ,３５ｂが設けられ、他端３２ｂは閉じられ、内部に設けられる移送手段３４よりなる所望数の往路Ｗ１と復路Ｗ２とにより形成される。本実施形態では、図示するように処理室３２は、内部に往路Ｗ１と復路Ｗ２とが１列づつ設けられた循環形式を採用している。
この処理室３２は、図示するものは代表的な例示であり、これに限ることなく例えば図には示さないが、長手方向の一端に配置される搬入位置Ｉに近接して開閉手段３３が設けられ、他方端３２ｃに配置される搬出位置Ｏに近接して図８に示すような開閉手段３３が設けられ、内部には所望数の往路Ｗ１と復路Ｗ２との双方が設けられてもよく、往路Ｗ１または復路Ｗ２の少なくとも何れか一方が設けられてもよい。
【００２１】
図１，図８において３７は予備開閉手段であり、この予備開閉手段３７は処理室３２に設ける前記開閉手段３３の後段に該開閉手段３３と対向して開閉可能に設けられることにより、前記開閉手段３３と前記予備開閉手段３７とは成形品３が該開閉手段３３と予備開閉手段３７との間に位置する空間領域３８に搬入または搬出されると、交互に位相を違えて開閉操作が行われる。このように、成形品３が開閉手段３３と予備開閉手段３７との間に位置する空間領域３８に搬入または搬出されると、開閉手段３３と予備開閉手段３７とが交互に位相を違えて開閉操作が行われるようにしたのは、処理室３２内の気密性を維持し、無駄な熱や蒸気が処理室３２から漏洩するのを防止するためである。
【００２２】
また、前記開閉手段３３および予備開閉手段３７は、開口３５ａ,３５ｂの全部または大部分を占める大きさに形成され、開口３５ａ,３５ｂに対し開閉可能に設けられる戸板３９、および該戸板３９に一端が連結されるワイヤー４０を巻取ドラム４１に捲回するモータＭ２よりなる。また、モータＭ２の負荷を軽減するために、錘Ｇをワイヤー４０の他端に取付ることにより負荷を軽減してもよい。
【００２３】
前記移送手段３４は、図２、図３に示すように前記コンベア１３と同様に、例えばモータＭの駆動力を受動して回転する所望複数のスプロケット１４と、該スプロケット１４の外周に巻回され台車１５が移動可能にコロ１６を装設した多数のチェーン素子１７ａを連結したチェーン１７等の動力伝達部品とにより形成される。しかし、図示するものは好適例であり、これに限らず、例えばローラコンベア、ベルトコンベアであってもよい。
【００２４】
また、処理室３２内に設けられる所望数の往路Ｗ１から復路Ｗ２へと成形品３を受け渡すための移送手段３６は、例えば図２に示すようにシリンダを駆動源とするプッシャ４２が使用してパレット１毎成形品３を往路Ｗ１から復路Ｗ２に押圧移動するほか、図３に示すように往路Ｗ１と復路Ｗ２との移送手段３４の端部に交叉して配置されるスプロケット１４′の外周に巻回されコロ１６′を装設した多数のチェーン素子１７′ａよりなるチェーン１７′をシリンダ駆動される起伏杆４３を起動または伏動することにより往路Ｗ１と復路Ｗ２との移送手段３４′のチェーン１７′に対して僅か上昇するか同高さに降下させることによりパレット１毎成形品３を往路Ｗ１から復路Ｗ２に受け渡すようになっている。
【００２５】
４４は製品取出機構部であり、この製品取出機構部４４により処理済の成形品３はパレット１から排出コンベア４５により搬送される木製パレット４６上に移送されて製品を得るほか、空のパレット１は取出コンベア４７から洗浄コンベア４８に設けた図には示されない回転ブラシの払拭により清掃された後に前記コンベア１３に移送され、再使用に供される。
【００２６】
本発明の一実施形態は以上の構成からなり、セメントモルタル製品を成形するのに先ず成形機２により成形された成形品３は、その後加熱することにより乾燥されたり、蒸気により加湿して養生される等の後処理を行うために移送手段としてのコンベア１３にて移送されるパレット１上に載置され、処理室３２に向かって移送されて行く。
この際、未養生の成形品３をパレット１上に載置させて移送を行う等するのは、成形品３が振動や衝撃により崩れ易く、亀裂などを生じ易いのを保護し、精度や品質が良く、歩留まりを良くするためである。
【００２７】
次いで、成形品３がパレット１を介してコンベア１３により順次搬送されて来ると、コンベア１３の傍らに所定の間隔Ｋ１をあけて配置したセンサーＳ１，Ｓ２により搬入・搬出手段１１に移送されて来る成形品３の個数が検知され、センサーＳ１，Ｓ２の信号に基づいてストッパ１８がコンベア１３に突出することによりコンベア１３により移送されて来る後続の成形品３から後処理を行う成形品３を１ブロック毎に分離する。図示する本実施形態では、３個毎に１ブロックを形成して後段の搬入・搬出手段１１に供給されるようになっている。
【００２８】
そして、成形品３がコンベア１３上を３個毎に１ブロックとして順次、搬入・搬出手段１１に送られて来ると、右側の挟持部材１２Ａ,１２Ａの駆動源２２のシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが架台フレームＦの上面を基準面として伸びるので、昇降板２３は案内棒２８,２８に案内されながら３個毎に１ブロックを形成してパレット１上に載置されている成形品３に対して降下されて行く。この時、昇降板２３の本体ケース２３Ａの左右に軸２９により中間部が枢着され、基端部が軸３０にてシリンダ３１のシリンダ・ロッド３１Ａの先端に枢着されている爪部材２４,２４は、シリンダ・ロッド３１Ａが縮んでいるので、開いている。
【００２９】
その後、昇降板２３が最低位置に降下すると、シリンダ３１が駆動してシリンダ・ロッド３１Ａが伸長するので、爪部材２４,２４は軸２９を中心として閉じ、３個の成形品３を１ブロックとしてパレット１毎挟持する（図４参照）。
【００３０】
この際、本実施形態で使用されるパレット１は、例えば図９ないし図１１に示すように剛性材により形成され、パレット本体１Ａの周囲に配した外回り縁材４の上面または下面の一面に位置決め手段５として外回り縁材４の厚みＴよりも長い長さＬの位置決めピン８が所望数設けられているので、コンベア１３に対してパレット本体１Ａとの間に間隙が確保されるため、右側の挟持部材１２Ａ,１２Ａの爪部材２４,２４の挟持は容易かつ確実になる。
【００３１】
それから、再びシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが架台フレームＦの上面を基準面として縮むので、昇降板２３は案内棒２８,２８に案内されながら上昇されるため、爪部材２４,２４により挟持されている成形品３は３個を１ブロックとしてパレット１毎最高位置まで上昇される。
【００３２】
その後、搬入・搬出手段１１のモータＭ１を駆動することによりモータシャフトに装設したピニオン２５が回転されると、該ピニオン２５に歯合されるピニオン２６はラック２７に歯合されながら回転されるので、３個を１ブロックとしてパレット１毎挟持している右側の挟持部材１２Ａ,１２Ａとして爪部材２４,２４を有するベース体２１は車輪２０が回転されて案内軌条部１９に沿って水平方向Ｙへ架台フレームＦの上方を搬入位置Ｉに向かって移動される。
【００３３】
そして、再び右側の挟持部材１２Ａ,１２Ａの駆動源２２のシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが架台フレームＦの上面を基準面として伸びることにより、昇降板２３が案内棒２８,２８に案内されながら降下するので、３個毎を１ブロックとして爪部材２４,２４によりパレット１毎挟持されている成形品３は、移送手段３４の所望位置、すなわち搬入位置Ｉへと降下して行く。
【００３４】
次いで、３個毎を１ブロックとして右側の挟持部材１２Ａ,１２Ａとして爪部材２４,２４によりパレット１毎挟持されている成形品３が、搬入位置Ｉに到達すると、シリンダ３１が駆動し、シリンダ・ロッド３１Ａが架台フレームＦの上面を基準面として縮むので、基端部が軸３０にてシリンダ３１のシリンダ・ロッド３１Ａの先端に枢着されている爪部材２４,２４が開き、成形品３は３個を１ブロックとしてパレット１毎搬入・搬出手段１１の移送手段３４上の台車１５上に受け渡される。
【００３５】
このように、コンベア１３と、搬入・搬出手段１１との間で前述の操作・手順が繰り返し行われることにより搬入・搬出手段１１に対して移送手段３４の搬入位置Ｉには成形機２にて成形された成形品３が、３個を１ブロックとしてパレット１を介して順次、所望数段積み重ねられる。
【００３６】
この際、パレット１は、例えば図９ないし図１１に示すように剛性材により形成され、パレット本体１Ａの周囲に配置した外回り縁材４の上面または下面の一面に位置決め手段５として外回り縁材４の厚みＴよりも長い長さＬの位置決めピン８が所望数設けられ、しかも外回り縁材４の上面または下面の対応する他面には上段または下段に配置される位置決めピン８の先端部６を受け入れる凹面部７を設けているので、成形品３を載置するために積み重ねられるパレット１相互間の位置決めが迅速かつ確実に行え、振動を受けても積み重ね状態が崩れることがなく、パレット１相互間には空隙１０が確保される。この空隙１０は左右の挟持部材１２Ａ,１２Ｂの爪部材２４,２４；２４,２４の挟持を容易かつ確実になすのと、後述の処理室３２内での後処理を行う場合に、熱と蒸気とを効率良く成形品３に付与することができ、高精度にして且つ高品質の成形品３を後処理できる。
【００３７】
そして、再び駆動源２２のシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが縮み、架台フレームＦの上面を基準面として昇降板２３および爪部材２４,２４は上昇する。
また、搬入・搬出手段１１のモータＭ１を駆動することによりモータシャフトに装設したピニオン２５が回転され、該ピニオン２５に歯合されるピニオン２６はラック２７に歯合されながら回転されるので、左右の挟持部材１２Ａ,１２Ｂの爪部材２４,２４を有するベース体２１は、車輪２０が回転され、架台フレームＦ上の案内軌条部１９に沿って水平方向Ｙへ旧位に復し、コンベア１３から搬入位置Ｉへの成形品３の次期の搬入に備える。
【００３８】
その後、処理室３２における移送手段３４のモータＭを駆動すると、このモータＭの駆動力を受動して上流側のスプロケット１４が回転するので、このスプロケット１４の外周に巻回され、コロ１６を装設した多数のチェーン素子１７ａよりなるチェーン１７等の動力伝達部品が台車１５を移送するため、この台車１５上にパレット１を介して載置された成形品３は、３個を１ブロックとして処理室３２の一端３２ａに搬入位置Ｉに臨んで設けられる開口３５ａ内の往路Ｗ１へと移送されて行く。
【００３９】
ところで、処理室３２の長手方向の一端３２ａの内部には、搬入位置Ｉに近接して設けられた開閉手段３３は、モータＭ２により巻取ドラム４１にワイヤー４０が捲回されて戸板３９が上方へ牽引されることにより開口３５ａが全部または大部分が開かれている。また、処理室３２の他端３２ｂ内に復路Ｗ２に対応して搬出位置Ｏに近接して設けられる開閉手段３３の戸板３９も、搬入位置Ｉ側の開閉手段３３と同様に同期してモータＭ２により巻取ドラム４１にワイヤー４０が捲回されて上方へ牽引されることにより開口３５ｂが開かれるようになる。
【００４０】
また、処理室３２には、搬入位置Ｉ側の開閉手段３３の後段に該開閉手段３３と対向して予備開閉手段３７が設けられているので、３個を１ブロックとしてパレット１毎成形品３が移送手段３４により該開閉手段３３と予備開閉手段３７との間に位置する空間領域３８に搬入または搬出されると、その時、予備開閉手段３７は閉じられ、処理室３２内の気密性を維持している。その後、開閉手段３３はモータＭ２が駆動して巻取ドラム４１からワイヤー４０が繰り出されて戸板３９が降下し、戸板３９により開口３５ｂが閉じられると、今度は予備開閉手段３７はモータＭ２が駆動し巻取ドラム４１にワイヤー４０が捲回されて上方へ戸板３９が牽引されることにより開口３５ａは開かれる。すなわち、予備開閉手段３７と開閉手段３３とは交互に位相を違えて開閉操作が行われる。このように、成形品３が開閉手段３３と予備開閉手段３７との間に位置する空間領域３８に搬入または搬出されると、開閉手段３３と予備開閉手段３７とが交互に位相を違えて開閉操作が行われるため、処理室３２内の気密性が維持され、熱や蒸気が処理室３２から不用意に漏洩するのを防止し、無駄なエネルギー消費が防止される。
【００４１】
こうして、３個を１ブロックとしてパレット１毎所望数段積み重ねられた成形品３は、移送手段３４により一括して処理室３２内を搬入位置Ｉ側の予備開閉手段３７を通過して往路Ｗ１を移送され、搬出位置Ｏ側の復路Ｗ２での予備開閉手段３７を通過するまでの間、処理室３２内で後処理が行われる。
【００４２】
この際、前述のように成形品３が載置され、積み重ねられているパレット１相互間には、位置決めピン８により収容空間部９に連通される空隙１０が確保されるので、この空隙１０を通じて熱や蒸気が収容空間部９内のセメントモルタルにより形成される成形品３に円滑かつ確実に伝達されて加熱、加湿が行われるため、成形品３の養生が無駄な熱や蒸気を要することなく効率的に行え、高精度且つ高品質に仕上がる。
【００４３】
また、処理室３２内での往路Ｗ１から復路Ｗ２への成形品３の受け渡しも、例えば図２に示すようにシリンダの駆動によるプッシャ４２の押圧によりパレット１毎成形品３を往路Ｗ１から復路Ｗ２へと受け渡しが行われるほか、図３に示すように往路Ｗ１と復路Ｗ２との移送手段３４の端部に交叉して配置されるスプロケット１４′の外周に巻回されコロ１６′を装設した多数のチェーン素子１７′ａよりなるチェーン１７′をシリンダ駆動により起伏杆４３を起動または伏動することにより往路Ｗ１と復路Ｗ２との移送手段３４のチェーン１７に対して僅か上昇するか同高さに降下させることによりパレット１毎成形品３を往路Ｗ１から復路Ｗ２に受け渡すこともでき、成形品は往路Ｗ２の移送手段３４により移送されて行くうちに後処理が行われる。
【００４４】
このようにして処理室３２内にて養生等の後処理が行われると、前述のように処理室３２の他端３２ｂの内部に搬出位置Ｏに近接して設けた予備的開閉手段３７と、開閉手段３３とは、モータＭ２が駆動して巻取ドラム４１にワイヤー４０が捲回されて上方へ戸板３９が牽引することにより交互に位相を違えて開閉操作が行われるので、後処理が終えた成形品３はパレット１を介して積み重ねられたまま搬入・搬出手段１１の搬出位置Ｏへと一括して搬出される。しかも予備的開閉手段３７と、開閉手段３３とは、戸板３９が交互に位相を違えて開閉操作が行われので、処理室３２内の気密性が維持され、熱や蒸気が処理室３２から不用意に漏洩するのを防止し、無駄なエネルギー消費が防止される。
【００４５】
また、処理室３２内での成形品３の後処理は、図１２ないし図１４に示すような従来の成形品処理装置のように、処理室ｅ内に多段・多列の収納棚ｄを設け、この多段・多列の収納棚ｄに対して成形品ｂを処理室ｅの側面に対向して設けた搬入ステーションｆと搬出ステーションｇとにより搬入または搬出するのとは異なり、成形機２により成形され、パレット１に載置された成形品３は前述のように位置決め手段５により相互に位置決めされるパレット１を介して所望数段、積み重ねられて搬入位置Ｉから処理室３２内に一括して搬入されて後処理が行われ、処理室３２から積み重ね状態のまま搬出位置Ｏへ一括して搬出されるので、従来のように収納棚ｄの１つの棚に対する成形品ｂの搬入数と搬出数が限られることない。しかも、従来のように収納棚ｄを用いて後処理が行われるものではないので、収納棚ｄを収納するための上下のクリアランス等の余分な空間は不用になり処理室３２は構造が簡単で製作および組立が容易になり、しかも大型化することなく小型の処理室３２であっても成形品３の後処理数を飛躍的に増加して効率的な後処理が行える。しかも、従来のように、収納棚ｄを用いて成形品の後処理をするのとは異なり、積み重ね状態で後処理が行われるので、成形品３の大きさも制約を受けることなく、大型の成形品３を処理するのに適するとともにパレット１自体の構造も簡素化する。
【００４６】
このように、処理室３２への成形品３の搬入と搬出とは、搬入・搬出装置１１によりパレット１を介して所望数段積み重ねられた成形品３を処理室３２の長手方向の一端の搬入位置Ｉおよび搬出位置Ｏに臨んで設けられる開口３２ａ,３２ｂの全部または大部分、図示する実施形態では全部を占める大きさの戸板３９が開閉される開閉手段３３と予備開閉手段３７を通じて積み重ね状態のまま処理室３２に対して一括して搬入または搬出がなされるので、時間と手間を要することになく、迅速かつ効率的に後処理を行うことができる。
【００４７】
そして、成形品３がパレット１を介して積み重ねられたまま搬入・搬出手段１１の搬出位置Ｏへと搬出されると、今度は左側の挟持部材１２Ｂ,１２Ｂの駆動源２２のシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが伸び、昇降板２３は案内棒２８,２８に案内されながら３個毎に１ブロックが形成され、パレット１を介して所望数段積み重ねられている後処理が済んだ成形品３に対して降下されて行く。この時、爪部材２４,２４は、開いている。
【００４８】
そして、昇降板２３が降下し、シリンダ３１が駆動してロッド３１Ａが伸長するので、後処理が済んだ３個の成形品３を１ブロックとしてパレット１毎爪部材２４,２４が挟持する。
【００４９】
それから、再びシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが縮み、昇降板２３は上昇されるため、左側の挟持部材１２Ｂ,１２Ｂとして爪部材２４,２４により挟持された成形品３は３個を１ブロックとしてパレット１毎最高位置まで上昇される。
その後、搬入・搬出手段１１のモータＭ１が駆動され、モータシャフトに装設したピニオン２５が回転されると、該ピニオン２５に歯合されるピニオン２６はラック２７に歯合されながら回転されるので、３個を１ブロックとしてパレット１毎挟持している爪部材２４,２４を有するベース体２１は、車輪２０が回転されて架台フレームＦ上の案内軌条部１９に沿って水平方向Ｙへ取出コンベア４７の所望位置に移動される。
【００５０】
そして、再びシリンダ２２Ａが駆動し、シリンダ・ロッド２２Ｂが伸びて昇降板２３が降下するので、３個毎を１ブロックとして左側の挟持部材１２Ｂ,１２Ｂの爪部材２４,２４によりパレット１毎挟持されている成形品３は、取出コンベア４７の所望位置に降下し、シリンダ３１が駆動し、爪部材２４,２４が開くので、後処理が済んだ成形品３は３個を１ブロックとしてパレット１毎取出コンベア４７に受け渡される。
【００５１】
このように処理室３２内で後処理され、パレット１を介して積み重ねられている成形品３は、上記操作手順が繰り返して行われることによりパレット１を介して３個を１ブロックとして１段毎に搬出位置Ｏから取出コンベア４７へと順次受け渡される。
【００５２】
そして、製品取出機構部４４により後処理が済んだ成形品３は排出コンベア４５の木製パレット４６上に載置されて製品を得るとともに成形品３が取り出された空のパレット１は取出コンベア４７から洗浄コンベア４８に設けた図には示されない回転ブラシの払拭により清掃された後に前記コンベア１３に移送され、再使用に供される。
【００５３】
また上記実施形態では、処理室３２により成形品３の後処理を行うために、搬入・搬出手段１１によりパレット１を介して３個を１ブロックとして成形品３を搬入位置Ｉに移送したり、搬出位置Ｏから製品取出位置に移送したりする場合を代表的に説明したが、これは例示であり１ブロックを形成する成形品３およびパレット１の設置個数の増減変更は自由に行える。
【００５４】
また、上記実施形態では、処理室３２により成形品３の後処理を行うために、成形機２により成形された成形品３をパレット１を介して３個を１ブロックとして搬入位置Ｉに移送する場合に、搬入・搬出手段１１により１段づつ積み重ねるとともに、処理室３２にて後処理が済んで搬出位置Ｏに一括して搬出された積み重ね状態の成形品３を製品取出機構部４４に移送する場合に搬入・搬出手段１１により１段づつ行う場合を代表的に説明したが、これは例示であり、本発明は搬入・搬出手段１１の爪部材２４,２４の長さ、形状を変更することにより容易に所望数段毎にパレット１毎成形品３を効率よく搬入位置Ｉに移送したり、製品取出機構部４４に移送することができる。
【００５６】
【発明の効果】

【００５７】
また、前記パレットは、成形品が載置されるパレット本体の周囲に積み重ね可能に外回り縁材が設けられ、該外回り縁材の上面または下面の一面には前記外回り縁材の厚みよりも長い丈のピン状の位置決め手段が、所望数設けられ、前記パレット本体の前記外回り縁材の上面または下面の対応する他面には前記位置決め手段の先端部を受け入れ可能な凹面部が設けられているので、成形機により成形された成形品をパレット上に載置し、処理室内にて成形品の後処理を行うのにパレットを介して搬入し、積み重ねる場合や、後処理が済んだ成形品を倉庫等に保管するために積み重ねる場合に、容易かつ確実に上下のパレット相互の位置決めを行うことができ、崩れるのを確実に防止することができる。
【００５８】
また、位置決め手段は位置決めピンであり、該位置決めピンは、長さを外回り縁材の厚みよりも長い丈に形成されることにより前記位置決め手段を介して積み重ねられる上段および下段のパレット本体は、前記成形品の収容空間部に連通される空隙が形成され、この空隙に前記挟持部材が係脱可能に挟持されて前記パレット本体を前記搬入位置に所望数段積み重ねて搬送が迅速かつ確実に行われ、しかも前記処理室にてパレット本体が積み重ねられた状態で成形品の処理が行われるので、成形品がセメントモルタル、セラミックにより成形されている場合には、空隙を通じて熱や蒸気が積み重ねられた各段のパレット内の収容空間部内のセメントモルタル等により形成される成形品に円滑かつ確実に伝達されて加熱、加湿が行われるため、成形品の養生が無駄な熱や蒸気を要することなく効率的に行え、また、成形品が生ゴミ等を圧縮したり、魚油を圧搾した後の魚の搾りかすで成形されている場合には、空隙を通じて熱が積み重ねられた各段のパレット内の収容空間部内の成形品に円滑かつ確実に伝達されて加熱し、効率的に乾燥が行える。

Has been filed as a Japanese Patent Application No. 2-75469, for example, as a molded product processing apparatus that automatically carries out the product.
An outline of the molded product processing apparatus according to the invention of this application will be described with reference to FIGS.
The molded product processing apparatus includes a movable storage shelf d provided with shelves arranged in multiple stages and multiple rows for storing the molded product b molded by the molding machine a in a state of being placed on the pallet c. In the processing chamber e surrounding the storage shelf d, a carry-in station f provided on the side surface of the processing chamber e in order to carry the molded product b molded by the molding machine a into the storage shelf d, and in the processing chamber e. An unloading station g provided close to the side surface of the processing chamber e in order to unload the finished product from the storage shelf d at the same time as the unloading of the molded product b, and the loading position of the molded product b by the loading station f. Opening / closing means h having a plurality of door constituting plates i1, i2, i3... Having a size corresponding to the opening k through which the molded product b can pass through I ′, and the unloading position of the molded product b by the unloading station g O 'at least post-processed molding b is provided on the wall surface of the processing chamber e a closing means h 'having a plurality of door configurations plate i1, i2, i3 ··· of size corresponding to the opening k can pass. l is a molded product taking-out part.
Then, in order to process the molded product b molded by the molding machine a, the door component plates i1, i2, i3... Of the opening / closing means h provided at the carry-in position I ′ of the molded product b are opened / closed and molded. Molded product by carrying-in station f provided on the side surface of processing chamber e on shelves arranged in multi-stages / multi-rows of storage shelves d provided in processing chamber e through opening k formed to allow the size of product b to pass through. The molded product b is formed in a size that allows passage of the molded product b by opening and closing the door constituting plates i1, i2, i3... of the opening / closing means h ′ provided at the unloading position O ′ of the molded product b. Through the opening k, the molded product b that has been post-processed by the processing chamber e is unloaded from the unloading station g provided on the side surface of the processing chamber e from the shelf of the storage shelf d.
In this way, the molded product b can pass by opening and closing the door component plates i1, i2, i3... Of the opening / closing means h, h ′ provided at the carry-in position I ′ and the carry-out position O ′ of the molded product b. Since the molded product b is carried into and out of the shelf of the storage shelf d provided in the processing chamber e through the opening k formed at the same time, processing is performed at the time of carrying in and out the molded product b and the product. The atmosphere for the post-treatment in the chamber e was intended to effectively use energy and resources by effectively using fuels and materials without substantially changing the atmosphere. Further, the carry-in station f and the carry-out station g are provided opposite to each other with the processing chamber e interposed therebetween, and the carry-in and carry-out of the molded product b are performed at the same time. b, that is, by making the number of products carried out the same, the total number of the molded product b and the product in the processing chamber e is kept at the maximum number that can be stored in the processing chamber e without causing a space in the storage shelf d. It is what I did.
[0003]
[Problems to be solved by the invention]
However, the conventional molded product processing apparatus includes a multi-stage / multi-row storage shelf d in the processing chamber e, and the molded product b is carried into or out of the storage shelf d by the carry-in station f and the carry-out station g. Therefore, it takes time and effort to carry in and out. Further, since the number of articles b that are carried in and out of one shelf of the storage shelf d is limited, the number of post-treatments of the molded product b cannot be increased dramatically. Therefore, the processing chamber e itself is also increased in size. Further, since the size of the molded product b stored in the shelf of the storage shelf d is also restricted, it is not suitable for processing a large molded product b. In addition, the opening / closing means h and h 'for carrying the molded product b into and out of the processing chamber e are provided with a number of door constituting plates i1, i2, i3,. Since the opening k is formed by opening and closing the size of the molded product b so that the molded product b can pass through, the door component plates i1, i2, i3... must be opened and closed to drive the pump that sends pressure to the lifting cylinder s for opening and closing the door opening and closing plates i1, i2, i3. Requires a lot of power. In addition, the opening / closing means h and h 'itself have a complicated structure and require many parts, so that they cannot be easily manufactured and assembled.

The pallet 1 molded product 3 is transferred from the forward path W1 to the return path W2 by slightly raising or lowering the chain 17 '.
[0025]
Reference numeral 44 denotes a product take-out mechanism section. The molded product 3 processed by the product take-out mechanism section 44 is transferred from the pallet 1 onto a wooden pallet 46 conveyed by a discharge conveyor 45 to obtain a product, and an empty pallet 1 After being cleaned by wiping off a rotating brush (not shown) from the take-out conveyor 47 to the cleaning conveyor 48, it is transferred to the conveyor 13 and reused.
[0026]
One embodiment of the present invention has the above-described configuration, and in order to mold a cement mortar product, the molded product 3 first molded by the molding machine 2 is then dried by heating or humidified with steam and cured. In order to perform post-processing such as the above, it is placed on the pallet 1 transferred by the conveyor 13 as transfer means, and is transferred toward the processing chamber 32.
At this time, the uncured molded product 3 is placed on the pallet 1 and transferred, for example, to protect the molded product 3 from being easily broken by vibration or shock, and to be easily cracked. This is to improve the yield.
[0027]
Next, when the molded product 3 is sequentially conveyed by the conveyor 13 via the pallet 1, it is transferred to the loading / unloading means 11 by the sensors S 1 and S 2 arranged along the conveyor 13 with a predetermined interval K 1. The number of the molded products 3 is detected, and the molded product 3 to be post-processed from the subsequent molded products 3 transferred by the conveyor 13 by the stopper 18 protruding to the conveyor 13 based on the signals of the sensors S1 and S2 is 1 Separate each block. In the present embodiment shown in the figure, one block is formed for every three pieces and supplied to the subsequent loading / unloading means 11.
[0028]
When the molded product 3 is sequentially sent to the carry-in / out means 11 as one block every three on the conveyor 13, the cylinder 22A of the drive source 22 of the right clamping members 12A, 12A is driven, and the cylinder -Since the rod 22B extends with the upper surface of the gantry frame F as the reference plane, the lift plate 23 is formed on the pallet 1 by forming one block every three while being guided by the guide rods 28, 28. Go down to 3 At this time, the intermediate portion is pivotally attached to the left and right of the main body case 23A of the lifting plate 23 by the shaft 29, and the base end portion is pivotally attached to the tip of the cylinder rod 31A of the cylinder 31 by the shaft 30. 24 is open because the cylinder rod 31A is contracted.
[0029]
Thereafter, when the elevating plate 23 is lowered to the lowest position, the cylinder 31 is driven and the cylinder rod 31A is extended. Therefore, the claw members 24 and 24 are closed around the shaft 29, and the three molded products 3 are made one block. Each pallet 1 is clamped (see FIG. 4).
[0030]
At this time, the pallet 1 used in this embodiment is formed of a rigid material as shown in FIGS. 9 to 11, for example, and is positioned on one surface of the upper surface or the lower surface of the outer periphery material 4 arranged around the pallet body 1A. Since a desired number of positioning pins 8 having a length L longer than the thickness T of the outer peripheral edge member 4 are provided as means 5, a gap is secured between the conveyor 13 and the pallet body 1A. The clamping of the claw members 24, 24 of the clamping members 12A, 12A is easy and reliable.
[0031]
Then, the cylinder 22A is driven again, and the cylinder rod 22B contracts with the upper surface of the gantry frame F as the reference plane. Therefore, the elevating plate 23 is raised while being guided by the guide rods 28, 28. The sandwiched molded product 3 is raised to the highest position for every pallet 1 with three blocks as one block.
[0032]
Thereafter, when the pinion 25 mounted on the motor shaft is rotated by driving the motor M1 of the loading / unloading means 11, the pinion 26 meshed with the pinion 25 is rotated while meshing with the rack 27. Therefore, the base body 21 having the claw members 24, 24 as the right holding members 12A, 12A holding the pallet 1 as one block is horizontally moved in the horizontal direction Y along the guide rail portion 19 as the wheels 20 are rotated. The upper frame frame F is moved toward the loading position I.
[0033]
Then, the cylinder 22A of the drive source 22 of the right clamping members 12A, 12A is driven again, and the cylinder rod 22B extends with the upper surface of the gantry frame F as the reference plane, whereby the elevating plate 23 is guided to the guide rods 28, 28. Therefore, the molded product 3 sandwiched between the pallets 1 by the claw members 24, 24 with every three pieces as one block is lowered to a desired position of the transfer means 34, that is, the carry-in position I.
[0034]
Next, when the molded product 3 clamped for each pallet 1 by the claw members 24 and 24 as the right-side clamping members 12A and 12A with three blocks as one block reaches the loading position I, the cylinder 31 is driven, Since the rod 31A contracts with the upper surface of the gantry frame F as the reference plane, the claw members 24 and 24 whose base end portions are pivotally attached to the tip of the cylinder rod 31A of the cylinder 31 by the shaft 30 are opened. Three pallets are transferred as one block onto the carriage 15 on the transfer means 34 of the carry-in / out means 11 for each pallet 1.
[0035]
In this manner, the above-described operation / procedure is repeatedly performed between the conveyor 13 and the carry-in / carry-out means 11, so that the carry-in / carry-out means 11 is brought into the carry-in position I of the transfer means 34 by the molding machine 2. The molded products 3 thus molded are stacked in a desired number of stages sequentially through the pallet 1 with three as one block.
[0036]
At this time, the pallet 1 is formed of a rigid material, for example, as shown in FIGS. 9 to 11, and the outer edge material 4 as a positioning means 5 on one surface of the upper surface or the lower surface of the outer edge material 4 arranged around the pallet body 1 A. A desired number of positioning pins 8 having a length L longer than the thickness T of the outer peripheral edge member 4 are provided, and the distal end portion 6 of the positioning pin 8 disposed in the upper or lower stage is provided on the other surface corresponding to the upper surface or the lower surface of the outer peripheral edge member 4. Since the concave surface portion 7 is provided, positioning between the pallets 1 stacked for placing the molded product 3 can be performed quickly and reliably, and the stacked state does not collapse even when subjected to vibration. A gap 10 is secured between them. The gap 10 can easily and reliably hold the claw members 24, 24; 24, 24 of the left and right holding members 12A, 12B, and heat and steam when performing post-processing in a processing chamber 32 described later. Can be efficiently applied to the molded product 3, and the high-quality molded product 3 can be post-processed with high accuracy.
[0037]
Then, the cylinder 22A of the drive source 22 is driven again, the cylinder rod 22B is contracted, and the elevating plate 23 and the claw members 24, 24 are raised with the upper surface of the gantry frame F as a reference plane.
Further, by driving the motor M1 of the loading / unloading means 11, the pinion 25 mounted on the motor shaft is rotated, and the pinion 26 meshed with the pinion 25 is rotated while meshing with the rack 27. The base body 21 having the claw members 24, 24 of the left and right clamping members 12A, 12B is restored to the old position in the horizontal direction Y along the guide rail portion 19 on the gantry frame F as the wheels 20 are rotated. To prepare for the next loading of the molded product 3 to the loading position I.
[0038]
Thereafter, when the motor M of the transfer means 34 in the processing chamber 32 is driven, the upstream sprocket 14 rotates by passively driving the motor M, so that it is wound around the outer periphery of the sprocket 14 and the roller 16 is mounted. Since a power transmission component such as a chain 17 composed of a large number of chain elements 17a transports the carriage 15, the molded product 3 placed on the carriage 15 via the pallet 1 is treated as three blocks. It is transferred to an outward path W1 in an opening 35a provided at one end 32a of the chamber 32 facing the loading position I.
[0039]
By the way, the opening / closing means 33 provided close to the loading position I inside the longitudinal end 32a of the processing chamber 32 has the wire 40 wound around the winding drum 41 by the motor M2 and the door plate 39 is moved upward. The opening 35a is wholly or most of the opening 35a is opened. Further, the door plate 39 of the opening / closing means 33 provided in the other end 32b of the processing chamber 32 in the vicinity of the unloading position O corresponding to the return path W2 is also synchronized with the motor M2 in the same manner as the opening / closing means 33 on the loading position I side. As a result, the wire 40 is wound around the winding drum 41 and pulled upward to open the opening 35b.
[0040]
Further, since the processing chamber 32 is provided with preliminary opening / closing means 37 opposite to the opening / closing means 33 at the subsequent stage of the opening / closing means 33 on the carry-in position I side, three pallets are formed as one block 3 Is carried into or out of the space region 38 located between the opening / closing means 33 and the preliminary opening / closing means 37 by the transfer means 34, the preliminary opening / closing means 37 is closed at that time, and the airtightness in the processing chamber 32 is maintained. is doing. After that, when the motor M2 is driven by the motor M2, the door 40 is lowered from the winding drum 41 and the door plate 39 is lowered, and the opening 35b is closed by the door plate 39, the preliminary opening / closing unit 37 is now driven by the motor M2. When the wire 40 is wound around the winding drum 41 and the door plate 39 is pulled upward, the opening 35a is opened. That is, the preliminary opening / closing means 37 and the opening / closing means 33 perform the opening / closing operation with alternately different phases. As described above, when the molded product 3 is carried into or out of the space region 38 located between the opening / closing means 33 and the preliminary opening / closing means 37, the opening / closing means 33 and the preliminary opening / closing means 37 are alternately opened / closed in different phases. Since the operation is performed, airtightness in the processing chamber 32 is maintained, heat and steam are prevented from inadvertently leaking from the processing chamber 32, and wasteful energy consumption is prevented.
[0041]
In this way, the molded products 3 that are stacked in a desired number of stages for each pallet 1 with three blocks as one block pass through the processing chamber 32 by the transfer means 34 through the preliminary opening / closing means 37 on the carry-in position I side, and pass through the outward path W1. Post-processing is performed in the processing chamber 32 until it passes through the preliminary opening / closing means 37 on the return path W2 on the unloading position O side.
[0042]
At this time, since the molded product 3 is placed and stacked between the pallets 1 stacked as described above, a gap 10 communicating with the accommodation space portion 9 by the positioning pin 8 is secured. Heat and steam are smoothly and reliably transmitted to the molded product 3 formed by cement mortar in the accommodating space 9 to be heated and humidified, so that curing of the molded product 3 does not require useless heat and steam. It can be done efficiently and finished with high accuracy and high quality.
[0043]
Also, the molded product 3 is transferred from the forward path W1 to the backward path W2 in the processing chamber 32, for example, as shown in FIG. 2, by pressing the pusher 42 by driving a cylinder, the pallet 1 molded product 3 is transferred from the forward path W1 to the backward path W2. As shown in FIG. 3, the roller 16 'is wound around the outer periphery of the sprocket 14' disposed at the end of the transfer means 34 between the forward path W1 and the backward path W2. The chain 17 'composed of a large number of chain elements 17'a is slightly raised or the same height as the chain 17 of the transfer means 34 in the forward path W1 and the backward path W2 by starting or sloping the undulation rod 43 by driving the cylinder. The molded product 3 for each pallet 1 can be transferred from the forward path W1 to the backward path W2 by lowering the pallet 1, and the molded product is post-processed while being transferred by the transfer means 34 in the forward path W2. It takes place.
[0044]
When post-treatment such as curing is performed in the processing chamber 32 in this way, the preliminary opening / closing means 37 provided in the vicinity of the unloading position O inside the other end 32b of the processing chamber 32 as described above, The opening / closing means 33 is driven by the motor M2, the wire 40 is wound around the take-up drum 41, and the door plate 39 is pulled upward so that the opening / closing operation is performed with different phases. The molded product 3 is unloaded at once to the unloading position O of the loading / unloading means 11 while being stacked via the pallet 1. Moreover, the opening / closing operation of the preliminary opening / closing means 37 and the opening / closing means 33 is performed with the door plates 39 alternately in different phases, so that the airtightness in the processing chamber 32 is maintained, and heat and steam are not transmitted from the processing chamber 32. This prevents leakage and prevents unnecessary energy consumption.
[0045]
Further, the post-processing of the molded product 3 in the processing chamber 32 is provided with a multi-stage / multi-row storage shelf d in the processing chamber e as in the conventional molded product processing apparatus as shown in FIGS. Unlike the loading / unloading station (f) and the loading / unloading station (g), which is provided with the molded product (b) facing the side surface of the processing chamber (e), the molding machine (2) The molded products 3 that have been molded and placed on the pallet 1 are stacked in a desired number of stages through the pallet 1 that are positioned with respect to each other by the positioning means 5 as described above, and are collectively put into the processing chamber 32 from the loading position I. After being carried in, post-processing is performed, and the batch is carried out from the processing chamber 32 to the carry-out position O in a stacked state. The number is not limited. Moreover, since the post-processing is not performed using the storage shelf d as in the prior art, the extra space such as the upper and lower clearances for storing the storage shelf d becomes unnecessary, and the structure of the processing chamber 32 is simple. Manufacture and assembly are facilitated, and even in a small processing chamber 32 without increasing the size, the number of post-processing of the molded product 3 can be dramatically increased and efficient post-processing can be performed. In addition, unlike the conventional case where the post-processing of the molded product is performed using the storage shelf d, the post-processing is performed in a stacked state. It is suitable for processing the product 3 and simplifies the structure of the pallet 1 itself.
[0046]
In this way, the carrying-in and carrying-out of the molded product 3 into the processing chamber 32 are carried in at one end in the longitudinal direction of the processing chamber 32 of the molded product 3 stacked in a desired number of stages via the pallet 1 by the loading / unloading device 11. All or most of the openings 32a and 32b provided facing the position I and the unloading position O, in the illustrated embodiment, are opened and closed through the opening / closing means 33 and the preliminary opening / closing means 37 that are opened and closed. Since the processing chamber 32 is carried in or out as it is, post-processing can be performed quickly and efficiently without requiring time and labor.
[0047]
Then, when the molded product 3 is unloaded to the unloading position O of the loading / unloading means 11 while being stacked via the pallet 1, this time, the cylinder 22A of the driving source 22 of the left clamping members 12B and 12B is driven. The cylinder rod 22B is extended, and the lifting plate 23 is guided by the guide rods 28, 28, so that one block is formed for every three pieces. Go down to 3 At this time, the claw members 24 are open.
[0048]
Then, the elevating plate 23 is lowered, the cylinder 31 is driven, and the rod 31A is extended, so that the nail members 24 and 24 for each pallet 1 are sandwiched by the three molded products 3 that have been post-processed as one block.
[0049]
Then, the cylinder 22A is driven again, the cylinder rod 22B is contracted, and the elevating plate 23 is raised, so that three molded products 3 sandwiched by the claw members 24, 24 as the left clamping members 12B, 12B are 1 The pallet 1 is raised to the highest position as a block.
Thereafter, when the motor M1 of the loading / unloading means 11 is driven and the pinion 25 mounted on the motor shaft is rotated, the pinion 26 meshed with the pinion 25 is rotated while meshing with the rack 27. The base body 21 having the claw members 24, 24 sandwiching the three pallets 1 as one block is taken out in the horizontal direction Y along the guide rail portion 19 on the gantry frame F as the wheels 20 are rotated. It is moved to 47 desired positions.
[0050]
Then, the cylinder 22A is driven again, the cylinder rod 22B is extended, and the elevating plate 23 is lowered, so that the pallet 1 is clamped by the claw members 24, 24 of the left clamping members 12B, 12B every three blocks. Since the molded product 3 is lowered to a desired position on the take-out conveyor 47, the cylinder 31 is driven, and the claw members 24 and 24 are opened, the post-processed molded product 3 is divided into three blocks as one block. It is delivered to the takeout conveyor 47.
[0051]
In this way, the molded product 3 that has been post-processed in the processing chamber 32 and stacked via the pallet 1 is subjected to the above-described operation procedure repeatedly, so that three blocks are arranged via the pallet 1 as one block. Are sequentially transferred from the carry-out position O to the take-out conveyor 47.
[0052]
The molded product 3 that has been post-processed by the product take-out mechanism 44 is placed on the wooden pallet 46 of the discharge conveyor 45 to obtain a product, and the empty pallet 1 from which the molded product 3 has been taken out is removed from the take-out conveyor 47. After being cleaned by wiping off a rotating brush (not shown in the figure) provided on the cleaning conveyor 48, it is transferred to the conveyor 13 and reused.
[0053]
Moreover, in the said embodiment, in order to perform the post-process of the molded article 3 by the process chamber 32, the molded article 3 is transferred to the carrying-in position I by making 3 into one block via the pallet 1 by the carrying-in / out means 11. The case where the product is transferred from the carry-out position O to the product take-out position has been described as an example, but this is an example, and the number of installations of the molded product 3 and the pallet 1 forming one block can be increased or decreased freely.
[0054]
Moreover, in the said embodiment, in order to post-process the molded product 3 by the process chamber 32, the molded product 3 shape | molded by the molding machine 2 is transferred to the carrying-in position I by making three into one block via the pallet 1. FIG.
