Description

【０００１】
【発明の属する技術分野】
この発明は、細幅の板材（木材）を送りながらその側面に接着剤を塗布し、この板材を上下熱箱間へ間欠的に押し込んで並列状に接着固定することにより、幅の広い幅はぎ板を製作するための製造装置に関する。
【０００２】
【従来の技術】
細幅の板材の側面（そば面）に接着剤を塗布し、この板材を並列状に接着（幅はぎ）して幅の広い幅はぎ板を製作する場合、本出願人はこれを自動的に製作することのできる幅はぎ板の製造装置（ランバーコアコンポーザー）を、実公昭５３−３５５９４号ですでに提案した。
【０００３】
この幅はぎ板の製造装置は、下部熱箱の直上に上部熱箱を配置し、該上部熱箱は上下に可動でスプリングにより押し下げ弾性が付勢され、側面に糊が塗布された板材が押し込み板で間欠的に上下熱箱間に押し込まれると、板材は側面が互いに接着した状態で進み、上部熱箱の重量とスプリングの力により、板材は下部熱箱に常時押しつけられながら通過することになり、板材が上下熱箱の入口から出口まで通過する間に、上下熱箱での加熱により糊が乾燥して接着が完了し、多数の板材が並列した幅の広い幅はぎ板が得られることになる。
【０００４】
【発明が解決しようとする課題】
ところで、上記した幅はぎ板の製造装置は、上部熱箱の重量とスプリングの力により、板材を下部熱箱に常時押しつけることにより、板材に圧力をかけて保持し、上下熱箱間に押し込まれる板材の側面圧着を行うと共に、糊を乾燥させるような構造になっているが、前記したような構造であると、上下熱箱間に押し込まれた板材を保持している力は、上部熱箱の重量とスプリングの力のみのため、熱箱の材料押し込み側と材料排出側の間で確実に材料押し込み時の圧力が保持できないので、板材の接着不良の原因になっていた。
【０００５】
また、上記した幅はぎ板の製造装置は、上下の熱箱が材料押し込み側から材料排出側まで連続した一本もので製作されていたため、熱箱の長さにより装置の生産能力が制約され、かつ、接着剤の種類にあわせて熱箱の微妙な温度管理が不可能である。
【０００６】
さらに、上記した幅はぎ板の製造装置は、材料送入部に板材の先端が当接するストッパーを設け、このストッパーの設定位置を変更することにより、その設定位置に対応した一種類の長さの幅はぎ板の製造しかできず、装置の効率が悪いという問題がある。
【０００７】
そこで、この発明の課題は、板材の接着不良の発生がなく、しかも、上下熱箱の微妙な温度管理が可能となり、かつ、二種類の長さの板材を用いた幅はぎ板を同時に製造できる幅はぎ板の製造装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記のような課題を解決するため、請求項１の発明は、多数本の角パイプを上面が板材の支持面となるよう一定間隔で平行配置して形成した下部熱箱の直上に、同じく多数本の角パイプを一定の間隔で平行に配置して形成した上部熱箱を、上下対向面間に板材の通過可能な間隔を設けて上下可動に配置し、側面に糊が塗布された板材を、前記下部熱箱と上部熱箱の間に、その長さ方向と直交する方向に順次押し込み、この板材を前記上部熱箱によるスプリングでの押し下げ力と自重で押しつけながら通過させることにより、各板材を糊によって並列状態に接続するようにした幅はぎ板の製造装置において、前記下部熱箱の板材押し込み側となる前部の位置に、板材を載せる上面が下部熱箱と同一面になる定盤を配置し、この定盤の直上で上部熱箱を形成する角パイプ間の位置に、前記定盤上の板材を押圧する前部板材押さえ機構を配置し、前記定盤に向けて供給された板材をこの定盤と前部板材押さえ機構の間へ間歇的に押出す押し込み機構を設け、前記下部熱箱の板材排出側となる後部の位置で、この下部熱箱を形成する角パイプの間に、板材受け台を下部熱箱の上面と同一面になるように設け、前記板材受け台の直上で上部熱箱を形成する角パイプの間に、板材受け台上の板材を押圧する後部板材押さえ機構を設けた構成を採用したものである。
【０００９】
請求項２の発明は、請求項１の発明において、材料押さえ機構が、押さえ部材をリンクで材料押し込み方向に揺動自在となるよう吊持し、この押さえ部材をシリンダで揺動させるようになっている構成を採用したものである。
【００１０】
請求項３の発明は、請求項１又は２の発明において、下部熱箱と上部熱箱のそれぞれが、第一セクションと第二セクションに分割した構造になっている構成を採用したものである。
【００１１】
請求項４の発明は、請求項１乃至３の発明において、定盤の前部に材料送り機構を配置し、この材料送り機構の中間位置に材料送入面に対して出没自在となるストッパーを設けた構成を採用したものである。
【００１２】
【発明の実施の形態】
以下、この発明の実施の形態を図示例と共に説明する。
【００１３】
図１は幅はぎ板の製造装置を示す平面図、図２は同正面図、図５は同上の要部縦断面図である。
同図において、幅はぎ板の製造装置の主要構成部材は、ベースフレーム１に一定の間隔をおいて、水平の状態で設けた下部熱箱２と、その直上に板材Ａの通過可能な間隔を設けて対向状に配置した上部熱箱３と、下部熱箱２の板材押し込み側となる前部に該下部熱箱２と同一面になるように配置した定盤４と、この定盤４の前部に板材Ａを長さ方向に送るよう配置した材料送り機構５と、材料送り機構５の送り方向前部に配置した材料送入コンベア５Ｂと、材料送り機構５上の板材Ａを定盤４上へ間欠的に押し出す押し込み機構６と、前記上部熱箱３の材料押し込み側で定盤４の直上の上部熱箱３と上部熱箱３の間に配置した前部板材押さえ機構７と、前記下部熱箱２の板材排出側となる後部に下部熱箱２と下部熱箱２間に該下部熱箱２と同一面となるように設けた板材受け台８と、上部熱箱３の材料排出側端部でこの板材受け台８の直上に配置した後部板材押さえ機構９と、上下熱箱２、３間の材料排出側に設けた取り出しコンベア１０とからなり、上下熱箱２、３の材料押し込み側と材料排出側を除く周面は、断熱用のカバー１１、１２で覆われている。
前記下部熱箱２は、多数本の角パイプ２ａを上面が板材支持面となるようベースフレーム１に一定の間隔で水平に並べ、その内部が温湯、蒸気、温風等の加熱源の通路になっていると共に、上部熱箱３も下部熱箱２と同様の多数本の角パイプ３ａを用い、下部熱箱２の角パイプ２ａの直上に該角パイプ３ａが平行状態で位置するよう配置され、角パイプ３ａの内部が加熱源の通路になっている。
【００１４】
上記下部熱箱２と上部熱箱３の対向面間は、図３の左側が板材Ａの材料押し込み側となり、この対向面間に対して板材Ａはその長さ方向が角パイプ２ａ、３ａの長さ方向と直交する状態で間欠的に押し込まれて移動することになる。
【００１５】
下部熱箱２と上部熱箱３は、それぞれが、略中間部の位置で第一セクション２Ａ、３Ａと第二セクション２Ｂ、３Ｂに分割した構造になっている。このように、下部熱箱２と上部熱箱３を第一セクション２Ａ、３Ａと第二セクション２Ｂ、３Ｂに分割した構造にすると、第一セクション２Ａ、３Ａと第二セクション２Ｂ、３Ｂにおいて各セクション単位で温度の調整や変更が行えることになり、また、上下熱箱２、３をセクション単位で増減することが可能となるため、生産能力を調整することができる。
【００１６】
下部熱箱２はベースフレーム１に固定されているのに対し、上部熱箱３は、第一セクション３Ａと第二セクション３Ｂのそれぞれの角パイプ３ａが、ベースフレーム１の該上部熱箱３よりも上部に位置する上部横桟１３、１４、１５に、下降限位置が調整できる条件で上下可動となるよう吊り下げ状に取り付けられ、スプリング１６での押し下げ力と自重で下部熱箱２上の板材Ａを押圧するようになっている。
【００１７】
前記下部熱箱２の板材押し込み側の前部に配置した定盤４は、板材Ａが数枚載る程度の幅と、角パイプ２ａの並列方向の全長にわたる長さを有し、図５に示すように角パイプ２ａの上面と同一面になるようベースフレーム１に水平状態で固定され、この定盤４の前部側の位置に配置した材料送り機構５は、ロール５ａにより板材Ａを水平に支持して長さ方向に送るローラコンベアで構成され、その搬送面は定盤４の上面と同じ高さになっている。
【００１８】
この材料送り機構５は、板材Ａを上下熱箱２、３への板材Ａの押し込み方向と直交方向に移送し、その先端部には、送られてきた板材Ａの先端が当接することにより、該板材Ａを停止させる最終ストッパー１７が設けられている。
【００１９】
材料送り機構５への材料挿入側前部には、板材Ａの一方側面に接着剤を塗布する糊付け装置１８を備えた材料送入コンベア５Ｂが配置されている。
【００２０】
この最終ストッパー１７は、板材Ａの送り方向に可動でスプリングにより、板材Ａの進入してくる側に位置する弾性が付勢され、送られてきた板材Ａの先端がこの最終ストッパー１７に当接して該ストッパー１７を押し込むと、リミットスイッチが作動し、後述する押し込み機構６を作動させることになる。
【００２１】
前記材料送り機構５の直上で複数箇所の位置に、上部横桟１３に取り付けたシリンダ１９によって、板材Ａの厚みに合わせて上下の位置が調整できるガイド部材２０が設けられ、材料送り機構５のロール５ａ上を送られてきた板材Ａをこのガイド部材２０で押圧することにより、板材Ａの跳ね上がり発生を防ぎ、板材Ａが最終ストッパー１７または、後述する中間ストッパーに当接して正確に停止するようにしている。
【００２２】
上記材料送り機構５を挟んで定盤４と反対側に位置し、材料送り機構５上の板材Ａを定盤４上へ間欠的に押し出す押し込み機構６は、図１と図４に示すように、材料送り機構５の長さ方向に平行する押し出し板２１を、該材料送り機構５のロール５ａの上面よりも高い位置に配置し、この押し出し板２１にベースフレーム１へ固定した複数のシリンダ２２を連結し、該シリンダ２２の伸縮動で、押し出し板２１を後退位置と前進位置の間を進退動させ、その前進動時に材料送り機構５のロール５ａ上にある板材Ａを上部熱箱３及び前部板材押さえ機構７と定盤４との間に押し出すようになっている。
【００２３】
前記上部熱箱３の材料押し込み側で定盤４の直上に配置した前部板材押さえ機構７は、図２乃至図６に示すように、上部横桟１３の下面で上部熱箱３における隣接する各角パイプ３ａ間の直上位置に、支持杆２３を角パイプ３ａの長さ方向に平行するよう固定し、この支持杆２３の両端に枢着したリンク２４で角パイプ３ａ間に納まる押さえ部材２５を取付け、該押さえ部材２５を角パイプ３ａの長さ方向に揺動自在とすると共に、上部横桟１３に固定したシリンダ２６の伸縮により上下動する連杆２７で押さえ部材２５を加圧するようにし、シリンダ２６の伸縮で押さえ部材２５を上下に揺動させるようになっている。
【００２４】
この前部板材押さえ機構７の押さえ部材２５は、予め板材Ａを押さえるための押さえ代だけ下降した位置にセットされており、角パイプ３ａの下面よりも押さえ代だけ下方に位置し、シリンダ２６が収縮しているときは、連杆２７が押さえ部材２５を押さえないので、押さえ部材２５は自在に上下でき、シリンダ２６が伸長すると、連杆２７が押さえ部材２５を押さえるため、定盤４上に押し出された板材Ａを定盤４に押圧固定することになる。
【００２５】
また、下部熱箱２の材料排出側となる後部の下部熱箱２と下部熱箱２の間に設けた材料受け台８は、角パイプ２ａの並列方向に長く、その上面が下部熱箱２と同一面になるようにベースフレーム１へ固定され、該材料受け台８の直上に配置した後部材料押さえ機構９は、上部横桟１５に取り付ける以外は前記入口側端部の前部板材押さえ機構７と同様の構造を有するので、同一部分に同一符号を付して説明に代える。
【００２６】
図７と図８は材料送り機構５において、送り方向の途中の位置でロール５ａの下部に設けた中間ストッパー３１を示し、材料送り機構フレーム３２の下部に設けた軸受３３で該ストッパー３１の後端を支持し、ストッパー３１は先端３１ａが上向きに屈曲し、シリンダ３４で上下に揺動が付与されるようになっており、中間ストッパー３１の先端３１ａは上昇したとき図７のように、ロール５ａによる板材Ａの支持搬送面よりも上方に突出し、送られてきた板材Ａがこの中間ストッパー３１の先端３１ａに当接して停止する。
【００２７】
また、中間ストッパー３１が下降位置にあるときは、先端３１ａがローラによる板材Ａの支持搬送面よりも下方に位置し、その上を板材Ａが通過することになる。
【００２８】
なお、中間ストッパー３１の位置は、上下熱箱２、３の幅方向における中央位置に対応するよう設定されていると共に、この中間ストッパー３１にも板材Ａが当接したのを検出するリミットスイッチを設け、中間ストッパー３１を使用する条件において、最終ストッパー１７のリミットスイッチと、この中間ストッパー３１のリミットスイッチの両方が作動した時点で押し込み機構６を作動させるようになっている。
【００２９】
この発明の幅はぎ板の製造装置は、上記のような構成であり、長い板材を用いて幅はぎ板を製造するには、材料送入コンベア５Ｂの受け取り側端部に板材Ａを一定の姿勢で順次供給する。
【００３０】
供給された板材Ａは、材料送入コンベア５Ｂによって長さ方向に送られ、その移動途中において糊付け機構１８で側面に接着剤が塗布された後、材料送り機構５に送入され、先端が最終ストッパー１７に当接した位置で停止する。このとき、中間ストッパー３１は下降位置に待機させ、板材Ａの通過に支障が生じないようにしておく。
【００３１】
板材Ａの先端が最終ストッパー１７に当接してこれをリミットスイッチが検出すると、押し込み機構６の押し出し板２１が一定ストロークを進退作動し、材料送り機構５のロール５ａ上の板材Ａを長さ方向と直交する方向に移動させて、上部熱箱３及び前部板材押さえ機構７と定盤４との間に押し出す。押し込み機構６は、最終ストッパー１７に板材Ａが当接するごとに押し出し板２１が進退作動し、板材Ａを上部熱箱３及び前部板材押さえ機構７と定盤４との間に順次押し出すことになる。
【００３２】
上部熱箱３及び前部板材押さえ機構７と定盤４との間に順次押し出される板材Ａは、先の板材Ａに圧接して前方に順送りし、並列状に接着した板材Ａは下部熱箱２と上部熱箱３の間に進入していく。定盤４上に位置する前部板材押さえ機構７は、板材Ａが押し出し板２１の前進により、前部板材押さえ機構７と定盤４との間に押し出されるときは、シリンダ２６は収縮し、押さえ部材２５への圧力が解除され、板材Ａが前部板材押さえ機構７と定盤４との間に押し出されて停止すると、シリンダ２６は伸長し、押さえ部材２５を押さえて板材Ａに圧力を加えて定盤４上に押圧固定し、その後に押し出し板２１が後退することとなり、次に板材Ａが供給されるときは、上記したような動作が繰り返されることとなる。
【００３３】
前記したように、シリンダ２６の伸縮動作は、押し出し板２１の進退動作に連動して行われることになる。
【００３４】
並列状に接着した板材Ａが下部熱箱２と上部熱箱３の間を進み、その先端側が下部熱箱２と上部熱箱３の材料排出側に達すると、板材受け台８とその上部に配置した後部板材押さえ機構９の間に進入する。
【００３５】
後部板材押さえ機構９は、シリンダ２６を伸長させて押さえ部材２５を常時押さえるようにしているため、板材Ａは板材受け台８に常時押圧され、板材Ａの進行方向に対し、常時ブレーキをかけている状態になる。
【００３６】
前記したような方法で板材Ａは、押し出し板２１の進退動作により下部熱箱２と上部熱箱３の間に順次押し出されるので、板材Ａが押し出されて次の板材Ａが押し込まれるまでの間は、板材Ａの進行方向に対して常に圧力が掛かった状態で、板材Ａは前部板材押さえ機構７により定盤４に押圧され、かつ、後部板材押さえ機構９により板材受け台８に押圧されているため、前部板材押さえ機構７と後部板材押さえ機構９との間で進行方向に対して常に圧力が保持され、圧力がこもった状態となり、並列状に接着した板材Ａは並列方向に圧着され、接着不良の発生を防止することができる。
【００３７】
また、並列状に接着した板材Ａは、下部熱箱２と上部熱箱３の間を進むとき、上部熱箱３の自重とスプリング１６の押圧で平面的にも加圧され、同時に下部熱箱２と上部熱箱３内に供給した熱源で加熱され、圧着部分の接着剤が乾燥することにより、板材Ａ相互が完全に固定化され、図９に示すような幅はぎ板ａが得られることになり、板材受け台８と後部板材押さえ機構９の間から出た幅はぎ板は、取り出しコンベア１０で受け取られて、所定の位置に搬送される。
【００３８】
なお、下部熱箱２と上部熱箱３へ熱源を供給する場合、接着剤の種類により、第一セクションと第二セクションの加熱条件を変えたいときは、第一セクションの上下熱箱２Ａ、３Ａと、第二セクションの上下熱箱２Ｂ、３Ｂへの供給熱源を変えることにより、第一セクションと第二セクションの温度条件を変えて温度管理することも可能である。
【００３９】
また、製造する幅はぎ板ａの幅の設定は、下部熱箱２と上部熱箱３の間に板材Ａを押し込むとき、側面への接着剤の塗布を省いた板材Ａを幅の設定条件に合わせた本数毎に組み入れるようにすればよい。
【００４０】
次に、上下熱箱２、３の幅の半分以下の長さを有する板材を用い、幅はぎ板を二枚同時に製造する場合を説明する。
【００４１】
この場合、材料送り機構５の途中に設けた中間ストッパー３１を作動可能にセットしておき、材料送入コンベア５Ｂの受け取り側端部に板材Ａを一定の姿勢で順次供給する。
【００４２】
供給された板材Ａは、材料送入コンベア５Ｂによって長さ方向に送られ、その移動途中において糊付け機構１８で側面に接着剤が塗布された後、最初の板材Ａは、中間ストッパー３１上を通過し、先端が最終ストッパー１７に当接した位置で停止する。中間ストッパー３１は、最初の板材Ａが通過すると、シリンダ３４の伸長で先端３１ａが搬送面上に突出し、次に送られてきた板材Ａはこの中間ストッパー３１に当接して停止する。
【００４３】
中間ストッパー３１への板材Ａの当接をリミットスイッチが検出すると、シリンダ３４が収縮し中間ストッパー３１を下降させた後、押し込み機構６の押し出し板２１が一定ストロークを進退作動し、最終ストッパー１７に当接した板材Ａと中間ストッパー３１に当接した板材Ａを同時に、上部熱箱３及び前部材料押さえ機構７と定盤４との間に押し出し、このようにして二枚の板材Ａの同時押し出しを繰り返すことにより、板材Ａは上下熱箱２、３間を二列に並んで移動する。
【００４４】
前部板材押さえ機構７と後部板材押さえ機構９及び上下熱箱２、３の作用は、前記と同様であり、これにより、上下熱箱２、３間の両側において、幅はぎ板を二枚同時に製造することができ、製造効率を大幅に向上させることができる。
【００４５】
【発明の効果】
以上のように、請求項１と２の発明によると、材料押し込み側に前部板材押さえ機構と材料排出側に後部板材押さえ機構を設けることにより、上下熱箱間に押し込んだ板材を前部板材押さえ機構と後部板材押さえ機構の間で圧力がこもった状態で圧接させることができ、幅はぎ板の製造における接着不良の発生を防止することができる。
【００４６】
また、請求項３の発明によると、下部熱箱と上部熱箱のそれぞれを、第一セクションと第二セクションに分割したので、上下熱箱をセクション単位で増減することが可能になり、幅はぎ板の生産能力を調整することができると共に、熱箱の温度管理もセクション単位で行うことができ、しかも、接着剤の種類に応じた加熱条件の対応が可能になる。
【００４７】
さらに、請求項４の発明によると、定盤の前部に材料送り機構を配置し、この材料送り機構の中間位置に材料送入面に対して出没自在となるストッパーを設けたので、同時に二種類の幅はぎ板の製造が可能となり、装置の稼働効率が向上する。

The lower heat box 2 has a large number of square pipes 2a arranged horizontally on the base frame 1 at regular intervals so that the upper surface thereof is a plate material support surface, and the inside thereof serves as a passage for a heating source such as hot water, steam, hot air, etc. In addition, the upper heat box 3 also uses the same number of square pipes 3a as the lower heat box 2, and the square pipes 3a are arranged in parallel with the square pipes 2a of the lower heat box 2. The inside of the square pipe 3a is a passage for a heating source.
[0014]
Between the opposing surfaces of the lower heat box 2 and the upper heat box 3, the left side of FIG. 3 is the material pushing side of the plate material A, and the length direction of the plate material A is between the opposing surfaces of the square pipes 2a and 3a. It is pushed in intermittently in a state perpendicular to the length direction.
[0015]
Each of the lower heat box 2 and the upper heat box 3 is divided into first sections 2A, 3A and second sections 2B, 3B at substantially intermediate positions. As described above, when the lower heat box 2 and the upper heat box 3 are divided into the first sections 2A, 3A and the second sections 2B, 3B, each section is divided into the first sections 2A, 3A and the second sections 2B, 3B. The temperature can be adjusted and changed in units, and the upper and lower heat boxes 2 and 3 can be increased or decreased in sections, so that the production capacity can be adjusted.
[0016]
The lower heat box 2 is fixed to the base frame 1, whereas the upper heat box 3 has the square pipes 3 a of the first section 3 </ b> A and the second section 3 </ b> B than the upper heat box 3 of the base frame 1. Are attached to the upper horizontal rails 13, 14, 15 located at the upper part so as to be movable up and down under the condition that the lower limit position can be adjusted. The plate material A is pressed.
[0017]
The surface plate 4 arranged at the front side of the lower heat box 2 on the side where the plate material is pushed has a width on which several sheets of plate material A are placed and a length over the entire length in the parallel direction of the square pipes 2a, as shown in FIG. Thus, the material feed mechanism 5 fixed in a horizontal state to the base frame 1 so as to be flush with the upper surface of the square pipe 2a and arranged at the position on the front side of the surface plate 4 makes the plate material A horizontally by the roll 5a. It is composed of a roller conveyor that supports and feeds it in the length direction, and its conveying surface is the same height as the upper surface of the surface plate 4.
[0018]
The material feeding mechanism 5 moves the plate A in a direction orthogonal to the pushing direction of the plate A into the upper and lower heating boxes 2 and 3, and the tip of the fed plate A is brought into contact with the front end portion thereof. A final stopper 17 for stopping the plate A is provided.
[0019]
A material feeding conveyor 5 </ b> B including a gluing device 18 that applies an adhesive to one side surface of the plate A is disposed at the front side of the material insertion side to the material feeding mechanism 5.
[0020]
The final stopper 17 is movable in the feeding direction of the plate material A and is elastically biased by the spring on the side from which the plate material A enters, and the tip of the fed plate material A comes into contact with the final stopper 17. When the stopper 17 is pushed in, the limit switch is actuated, and the push-in mechanism 6 described later is actuated.
[0021]
A guide member 20 that can adjust the vertical position according to the thickness of the plate A is provided by a cylinder 19 attached to the upper horizontal rail 13 at a plurality of positions immediately above the material feeding mechanism 5. By pressing the plate material A sent on the roll 5a with this guide member 20, the plate material A is prevented from jumping up, and the plate material A comes into contact with the final stopper 17 or an intermediate stopper described later so as to stop accurately. I have to.
[0022]
As shown in FIGS. 1 and 4, the pushing mechanism 6 that is located on the opposite side of the surface plate 4 with the material feeding mechanism 5 interposed therebetween and intermittently pushes the plate A on the material feeding mechanism 5 onto the surface plate 4. The extrusion plate 21 parallel to the length direction of the material feeding mechanism 5 is arranged at a position higher than the upper surface of the roll 5a of the material feeding mechanism 5, and a plurality of cylinders 22 fixed to the base frame 1 on the extrusion plate 21. And the push-out plate 21 is moved back and forth between the retracted position and the advanced position by the expansion and contraction of the cylinder 22, and the plate material A on the roll 5a of the material feeding mechanism 5 is moved to the upper heat box 3 and the forward movement. Extrusion is performed between the front plate material pressing mechanism 7 and the surface plate 4.
[0023]
The front plate pressing mechanism 7 disposed immediately above the surface plate 4 on the material pushing side of the upper heat box 3 is adjacent to the upper heat box 3 on the lower surface of the upper horizontal rail 13 as shown in FIGS. A support rod 23 is fixed at a position directly above each of the square pipes 3a so as to be parallel to the length direction of the square pipe 3a, and a holding member 25 which is fitted between the square pipes 3a by links 24 pivoted to both ends of the support rod 23. The holding member 25 is made swingable in the lengthwise direction of the square pipe 3a, and the holding member 25 is pressurized by a linkage 27 that moves up and down by the expansion and contraction of the cylinder 26 fixed to the upper horizontal rail 13. The holding member 25 is swung up and down by the expansion and contraction of the cylinder 26.
[0024]
The pressing member 25 of the front plate pressing mechanism 7 is set in a position lowered by a pressing allowance for pressing the plate A in advance, and is positioned below the lower end of the square pipe 3a by a pressing allowance. Since the continuous member 27 does not press the pressing member 25 when contracted, the pressing member 25 can freely move up and down, and when the cylinder 26 extends, the continuous member 27 presses the pressing member 25, so that it is placed on the surface plate 4. The extruded plate material A is pressed and fixed to the surface plate 4.
[0025]
Further, the material support 8 provided between the lower lower heat box 2 and the lower heat box 2 on the material discharge side of the lower heat box 2 is long in the parallel direction of the square pipes 2a, and the upper surface thereof is the lower heat box 2. The rear material pressing mechanism 9 fixed to the base frame 1 so as to be in the same plane and disposed immediately above the material cradle 8 is a front plate material pressing mechanism at the end on the inlet side except that it is attached to the upper horizontal rail 15. 7 has the same structure as that of FIG.
[0026]
FIGS. 7 and 8 show an intermediate stopper 31 provided at the lower part of the roll 5a in the middle of the feeding direction in the material feeding mechanism 5, and a bearing 33 provided at the lower part of the material feeding mechanism frame 32 behind the stopper 31. The stopper 31 supports the end, the tip 31a is bent upward, and the cylinder 34 is swung up and down. When the tip 31a of the intermediate stopper 31 is lifted, as shown in FIG. The plate A that protrudes upward from the support conveyance surface of the plate A by 5a is brought into contact with the tip 31a of the intermediate stopper 31 and stopped.
[0027]
Further, when the intermediate stopper 31 is in the lowered position, the tip 31a is positioned below the supporting and conveying surface of the plate material A by the roller, and the plate material A passes therethrough.
[0028]
The position of the intermediate stopper 31 is set so as to correspond to the center position in the width direction of the upper and lower heating boxes 2, 3, and a limit switch for detecting that the plate material A is in contact with the intermediate stopper 31 is provided. The push-in mechanism 6 is activated when both the limit switch of the final stopper 17 and the limit switch of the intermediate stopper 31 are activated under the condition that the intermediate stopper 31 is used.
[0029]
The width peeling plate manufacturing apparatus of the present invention has the above-described configuration, and in order to manufacture a width cutting plate using a long plate material, the plate material A is placed in a certain posture at the receiving side end of the material feeding conveyor 5B. Supply sequentially.
[0030]
The supplied plate material A is sent in the length direction by the material feeding conveyor 5B, and the adhesive is applied to the side surface by the gluing mechanism 18 in the middle of the movement, and then fed into the material feeding mechanism 5, and the tip ends finally. Stops at the position where it comes into contact with the stopper 17. At this time, the intermediate stopper 31 is kept at the lowered position so that the passage of the plate A is not hindered.
[0031]
When the end of the plate A contacts the final stopper 17 and the limit switch detects this, the push-out plate 21 of the push-in mechanism 6 moves forward and backward by a fixed stroke, and the plate A on the roll 5a of the material feed mechanism 5 moves in the length direction. And is pushed out between the upper heat box 3 and the front plate material pressing mechanism 7 and the surface plate 4. In the push-in mechanism 6, each time the plate material A comes into contact with the final stopper 17, the push-out plate 21 moves forward and backward to sequentially push the plate material A between the upper heat box 3 and the front plate material pressing mechanism 7 and the surface plate 4. Become.
[0032]
The plate A that is sequentially pushed between the upper heat box 3 and the front plate holding mechanism 7 and the surface plate 4 is pressed forward against the plate A and forwardly fed, and the plate A bonded in parallel is the lower heat box. Enter between 2 and the upper heat box 3. When the plate A is pushed between the front plate holding mechanism 7 and the surface plate 4 by the advance of the pushing plate 21, the cylinder 26 contracts. When the pressure on the holding member 25 is released and the plate A is pushed between the front plate holding mechanism 7 and the surface plate 4 and stops, the cylinder 26 expands and presses the holding member 25 to apply pressure to the plate A. In addition, the pressing plate 21 is pressed and fixed, and then the extrusion plate 21 is retracted. When the plate material A is supplied next time, the above-described operation is repeated.
[0033]
As described above, the expansion / contraction operation of the cylinder 26 is performed in conjunction with the advance / retreat operation of the push-out plate 21.
[0034]
When the plate material A bonded in parallel advances between the lower heat box 2 and the upper heat box 3 and the leading end side reaches the material discharge side of the lower heat box 2 and the upper heat box 3, the plate material cradle 8 and the upper part thereof are placed. It enters between the rear plate material pressing mechanisms 9 arranged.
[0035]
Since the rear plate material pressing mechanism 9 extends the cylinder 26 so that the pressing member 25 is always pressed, the plate material A is always pressed by the plate material cradle 8 and always brakes the traveling direction of the plate material A. It will be in a state.
[0036]
The plate material A is sequentially pushed out between the lower heat box 2 and the upper heat box 3 by the forward / backward movement of the push-out plate 21 in the manner described above, and therefore, until the plate material A is pushed out and the next plate material A is pushed in. The plate material A is pressed against the surface plate 4 by the front plate material pressing mechanism 7 and is pressed against the plate material cradle 8 by the rear plate material pressing mechanism 9 in a state where pressure is always applied to the traveling direction of the plate material A. Therefore, the pressure is always maintained in the traveling direction between the front plate material pressing mechanism 7 and the rear plate material pressing mechanism 9 so that the pressure is accumulated, and the plate material A bonded in parallel is pressure-bonded in the parallel direction. Therefore, it is possible to prevent the occurrence of poor adhesion.
[0037]
Further, the plate material A bonded in parallel is pressed between the lower heat box 2 and the upper heat box 3 by the weight of the upper heat box 3 and the pressure of the spring 16 in a plane, and at the same time, the lower heat box 2 and the upper heat box 3 are heated by the heat source supplied, and the adhesive at the crimping part is dried, so that the plates A are completely fixed to each other, and a width stripping plate a as shown in FIG. 9 is obtained. Thus, the width peeling plate that has come out between the plate material receiving base 8 and the rear plate material pressing mechanism 9 is received by the take-out conveyor 10 and conveyed to a predetermined position.
[0038]
In addition, when supplying a heat source to the lower heat box 2 and the upper heat box 3 and changing the heating conditions of the first section and the second section depending on the type of adhesive, the upper and lower heat boxes 2A, 3A of the first section are used. It is also possible to control the temperature by changing the temperature conditions of the first section and the second section by changing the supply heat source to the upper and lower heating boxes 2B, 3B of the second section.
[0039]
In addition, the width of the width sheet a to be manufactured is set such that when the plate A is pushed between the lower heat box 2 and the upper heat box 3, the width of the plate A without applying the adhesive to the side surface is set. What is necessary is just to make it incorporate for every combined number.
[0040]
Next, a case will be described in which a sheet having a length equal to or less than half the width of the upper and lower heating boxes 2 and 3 is used to simultaneously manufacture two sheeting plates.
[0041]
In this case, the intermediate stopper 31 provided in the middle of the material feeding mechanism 5 is set so as to be operable, and the plate material A is sequentially supplied to the receiving side end of the material feeding conveyor 5B in a constant posture.
[0042]
The supplied plate A is sent in the length direction by the material feeding conveyor 5B, and after the adhesive is applied to the side surface by the gluing mechanism 18 in the middle of the movement, the first plate A passes over the intermediate stopper 31. Then, it stops at the position where the tip abuts against the final stopper 17. When the first plate material A passes through the intermediate stopper 31, the tip 31 a protrudes on the conveying surface due to the extension of the cylinder 34, and the plate material A fed next comes into contact with the intermediate stopper 31 and stops.
[0043]
When the limit switch detects the contact of the plate A with the intermediate stopper 31, the cylinder 34 contracts and lowers the intermediate stopper 31, and then the push-out plate 21 of the push-in mechanism 6 moves forward and backward by a fixed stroke, and the final stopper 17 is moved. The abutting plate A and the abutting plate A in contact with the intermediate stopper 31 are simultaneously extruded between the upper heat box 3 and the front material pressing mechanism 7 and the surface plate 4, and thus the two plates A are simultaneously formed. By repeating the extrusion, the plate A moves between the upper and lower heating boxes 2 and 3 in two rows.
[0044]
The actions of the front plate pressing mechanism 7, the rear plate pressing mechanism 9 and the upper and lower heating boxes 2 and 3 are the same as described above. It can be manufactured, and the manufacturing efficiency can be greatly improved.
[0045]
