Abstract
Description
特許文献1に記載された製本装置は、ブックブロックを起立状態に挟持し、予め設定された経路に沿って移動し得る1または2以上のクランパと、経路に沿って配置された無線綴じ製本処理を行う一連の処理ユニットを備えている。クランパは、ブックブロックを受け入れる開位置と、ブックブロックの両側を挟持する閉位置とをとる一対のクランプ板を有している。
そして、クランパがブックブロック供給位置にあるとき、開位置をとる一対のクランプ板間に、ブックブロック供給ユニットによってブックブロックが供給され、次いで、一対のクランプ板が閉位置をとり、その後、クランパがブックブロック供給位置を離れて一連の処理ユニットを順次通過する間に、ブックブロックが無線綴じ製本されるようになっている。
集積コンベヤは、それぞれ搬送方向に直角にのび、互いに間隔をあけて配置された複数本の回転軸と、各回転軸の一端側に固定された駆動ローラと、各回転軸に当該回転軸のまわりに回転自在に取り付けられた複数のアイドルローラと、駆動ローラの下側において搬送方向にのび、垂直面内において常時一方向に回転駆動されるエンドレスベルトを有している。
また、各アイドルローラの上面は搬送面を形成し、ブックブロック形成装置から排出されたブックブロックが横倒配置で搬送面上に置かれると、アイドルローラはブックブロックの重量によって回転軸に接触して回転軸とともに回転駆動され、それによってブックブロックが搬送される。
コンベヤベルトの搬送速度は集積コンベヤの搬送速度よりも速くなるように設定されている。
その後、ストッパが退避位置をとると、ブックブロックが置かれたアイドルローラが関係する回転軸とともに回転し、ブックブロックの搬送が再開される。
そして、この停止の間に、ブロック形成装置から排出されたブックブロックは、ブックブロック搬送装置の集積コンベヤ装置の搬送面上に集積される。
それによって、ブックブロック形成装置を連続運転させたままで、製本装置を一時停止させることができ、生産効率の低下を抑制することができる。
そして、このような場合には、ブックブロック形成装置および製本装置の運転を一時停止させて、崩れたブックブロックを手作業で除去しなければならず、生産効率の低下が著しかった。
あるいは、前記検出ユニットが、前記第2のストッパの上流側においてブックブロックの経路の上方に配置され、前記ブックブロックの経路に向けられた測距センサと、前記第2のストッパの下流側においてブックブロックの経路の外側に配置された光学センサと、からなっている。
また、第1のコンベヤの出口端、または第1および第2のコンベヤ間、または第2のコンベヤの入口端に第1のストッパを配置し、第1のコンベヤの搬送面上のブックブロックの経路の途中に第2のストッパを配置した。また、第1および第2のストッパが、ブックブロックを制止する制止位置と、ブックブロックの通過を許容する退避位置をとり得るようにした。
図1は、本発明の1実施例によるブックブロック搬送装置の斜視図である。図2(A)は、図1のブックブロック搬送装置の平面図であり、図2(B)は、図1のブックブロック搬送装置の正面図である。
こうして、エンドレスベルト11がモータ10によって回転せしめられ、それに伴って各回転軸6がブックブロックBを搬送する向きに回転駆動される。
また、第2のシャフト15の一端には、プーリー18が固定されている。
そして、エンドレスベルト17の上面はブックブロックBの搬送面22を形成する。
第2のコンベヤ12の搬送速度は第1のコンベヤ1の搬送速度よりも速くなるように設定される。
制止板24は、第2のコンベヤ12のエンドレスベルト17のそれぞれに対応する位置に、制止板24の上端縁から下向きに互いに平行にのびるスリット24aを有しており、それによって、制止板24は、エンドレスベルト17の回転運動を妨げることなく搬送面22を上下に横切ることができる。
エアシリンダ25のピストンロッド25aは、制止板24の運動方向に沿って運動し得るとともに、制止板24がピストンロッド25aに取り付けられている。
センサ26は光学センサからなり、ブックブロックBがセンサ26の検出エリアを遮り、センサ26がOFF状態からON状態に切り替わることでブックブロックBの通過が検出される。
コントローラ27は、第1のストッパ23が制止位置をとり、センサ26がブックブロックBを検出した時点で、製本装置へのブックブロックBの供給の準備が完了したものと判定する。
ブックブロックBの製本装置13への供給完了後、コントローラ27は第2のコンベヤ12を停止させる。
エアシリンダ30のピストンロッド30aは、制止板29の運動方向に沿って運動し得るとともに、制止板29がピストンロッド30aに取り付けられている。
第2のストッパ28(エアシリンダ25)には、コントローラ27が作動的に接続されている。
測距センサ31は、通常、測距センサ31から第1のコンベヤ1の搬送面4までの距離(第1の距離)を検出しているが、測距センサ31の下をブックブロックBが通過すると、測距センサ31からブックブロックBの上面までの距離(第2の距離)を検出する。
そして、第1の距離と第2の距離の差からブックブロックBの厚さが検出される。
こうして、測距センサ31は、ブックブロックBの通過およびブックブロックBの厚さを検出する。
そして、ブックブロックBが制止されている間に、第1のストッパ23の上流側に集積されたブックブロックBが順次製本装置13に供給される。
こうして、本発明のブックブロック搬送装置によれば、ブックブロックBの製本装置への供給が常に円滑かつ安定的に行われる。
そして、例えば、本発明のブックブロック搬送装置の第1のコンベヤ1の入口端2にブックブロック形成装置のブックブロック排出口を接続した場合には、ブックブロック形成装置を連続運転させたままで、製本装置を一時停止させ、停止の間に、ブックブロック搬送装置にブックブロックを崩れない状態で集積し、製本装置の運転を再開させたとき、集積したブックブロックを順次製本装置に円滑に供給することができ、それによって、生産効率の低下を防止することができる。
この場合、ブックブロックBの最上位の用紙(または折丁)の上面に、当該ブックブロックBを構成する用紙(または折丁)の枚数を示すバーコードまたは2次元コード等が予め印刷されており、第2の監視部33は、リーダーによって読み取られた用紙(または折丁)の枚数と、予め入力された用紙(または折丁)1枚当たりの厚さからブックブロックBの厚さを算出する。
この場合、所定時間は、第2のストッパ28が制止位置をとった後第1のストッパ23の上流側に集積されたブックブロックBの個数がゼロになるまでに要する時間よりも十分に長い時間として予め設定される。
図6の実施例は、図1~図5に示した実施例と、検出ユニットの構成および集積エリアに集積されたブックブロックの個数の監視の仕方が異なるだけである。よって、図6中、図1~図5に示したものと同じ構成要素には同一番号を付し、以下ではそれらの詳細な説明を省略する。
あるいは、ストッパ制御部34は、光学センサ35が再びOFF状態となった時点で、第2のストッパ28に退避位置をとらせる制御信号を送信する。
