【発明の属する技術分野】
本発明はパチンコ機を製造する過程で遊技盤に取り付けられる部品に用いられる開口部を穴あけ加工するルータ加工方法および装置に関する。
【０００２】
【従来の技術】
従来のルータ加工方法は、一表面を意匠盤面として形成した板状の遊技盤が意匠盤面を下に向けた格好でルータ加工機のテーブルに搭載された後、ルータ加工機の工具で遊技盤の裏面から遊技盤に開口部を穴あけ加工している（例えば、特許文献１参照）。

【発明が解決しようとする課題】
しかしながら、従来例は意匠盤面を傷つけないように保護する必要があることから、多数枚の遊技盤が意匠盤面を下に向けた格好で供給部に積み重ねられた状態において、ハンド機構が下降して積層された最上部の遊技盤を両側から掴んで上昇し、掴まれた遊技盤の意匠盤面がその下における遊技盤の裏面から離れた後に、ハンド機構が横移動して下降することによって、遊技盤がテーブルに搭載されるようになっている。このため、１台のルータ加工機で複数の遊技盤を一度に加工する場合、ハンド機構で複数の遊技盤を複数のテーブルに個別に供給する時間が長く、生産効率が悪いという問題点があった。
【０００５】
そこで、本発明は意匠盤面の側から工具で遊技盤に開口部を穴あけ加工することによって、意匠盤面を保護するとともに、生産効率を向上することができるルータ加工方法および装置を提供するものである。
【０００６】
【課題を解決するための手段】
本発明に係る複数の遊技盤を一組として遊技盤に開口部を形成するルータ加工装置は、遊技盤の意匠盤面を上に向けた格好で遊技盤を搬送する第一の搬送機構と、遊技盤の意匠盤面を上に向けた格好で受け入れる加工ステージと、第一の搬送機構と加工ステージとにそれぞれ分離して配置される第二の搬送機構と、遊技盤に被せられた加工治具を搬送する治具搬送機構とを備え、遊技盤は前記第二の搬送機構により、前記第一の搬送機構及び前記加工ステージにわたって搬送され、加工ステージは一組の遊技盤における最初の遊技盤が加工ステージに受け入れられたときに、最初の遊技盤に被せられた加工治具を保持する治具保持機構を備え、治具搬送機構は一組の遊技盤の加工が終了したときに治具保持機構から排出される加工治具を搬送することによって、遊技盤が意匠盤面を上に向けた格好で第一の搬送機構から第二の搬送機構を経由して加工ステージに供給されるので、その過程において、搬送や供給で遊技盤の意匠盤面を傷めることが防止できる。また、ルータ加工機が複数の加工ステージを有し、それぞれの加工ステージに遊技盤を個別に供給する場合においても、複数の遊技盤を第一の搬送機構で各々の加工ステージの前まで順に搬送し、各加工ステージの前に到達した遊技盤を第二の搬送機構で加工ステージごとに個別に供給することができるので、複数の遊技盤を複数の加工ステージのそれぞれに供給する時間が短くなり、生産効率を向上することができる。また、加工ステージが一組の遊技盤における最初の遊技盤が加工ステージに受け入れられたときに、最初の遊技盤に被せられた加工治具を保持する治具保持機構を備え、治具搬送機構が一組の遊技盤の加工が終了したときに治具保持機構から排出される加工治具を搬送するので、ルータ加工機での意匠盤面の剥がれ防止用の加工治具をルータ加工機に供給される遊技盤のそれぞれに被せる必要がなく、或る１つの種類における遊技盤の１組に対する穴あけ加工における最初の遊技盤に加工治具を被せて加工ステージに供給すればよいので、１つの種類における遊技盤に対しルータ加工機で使用する加工治具の枚数が少量となり、経済的に有利となる。しかも、１つの種類における遊技盤に対しルータ加工機での使用が終了した加工治具は第二の搬送機構および治具保持機構で加工ステージから取り出すことができるので、ルータ加工機からの加工治具の回収も適切に行うことができる。
また、本発明に係るルータ加工装置にあっては、治具保持機構が加工治具を保持・解放する電磁石を備えれば、電磁石への電力供給・遮断で加工治具が保持・解放されるので、リンク機構などを使用するハンド機構に比べ、治具保持機構での加工治具の取り扱いが容易となる。
【０００７】
【発明の実施の形態】
図１−図７は一実施形態であって、図１はルータ加工装置を平面的に示し、図２はルータ加工機１１を正面的に示し、図３は横搬送機構１２と前後搬送機構１３および治具搬送機構１４を側面的に示し、図４−図６はルータ加工工程を示し、図７は加工治具５の搬出動作を示す。
【０００８】
図１を参照し、ルータ加工装置について説明する。本実施形態では、遊技盤１が多品種少量の生産品であり、或る１つの種類における複数の遊技盤１を１組として穴あけ加工する場合、その１組における最初の遊技盤１は加工治具５が載せられた形態でルータ加工装置に供給され、同じ組のそれ以降の遊技盤１は加工治具５を載せない形態でルータ加工装置に供給される場合を例として説明する。遊技盤１は一表面を意匠盤面２として形成された板状であって、１つの対角線上に２つの位置決め孔３を備える。
【０００９】
加工治具５は遊技盤１における工具１７で穴あけされる開口部４の周りにおける意匠盤面２の剥がれを防止するものであって、合成樹脂からなる板状の裏面に形成された図外の凹部に遊技盤１を嵌め込むことで、遊技盤１の意匠盤面２を覆うとともに遊技盤１から横ずれしないように遊技盤１に搭載される一方、２つの位置決め孔６を遊技盤１の位置決め孔３と同軸状に対応する位置に備える。２つの位置決め孔６は加工治具５に固定された筒状の鉄のような磁性材からなる支持体７の中心孔になっている。加工治具５は遊技盤１に形成すべき開口部４よりも少し大きな開口部８を備える。
【００１０】
ルータ加工装置はルータ加工機１１、第一の搬送機構としての横搬送機構１２、第二の搬送機構としての前後搬送機構１３、治具搬送機構１４、制御装置１５を備える。ルータ加工機１１は加工ステージ１６と工具１７が対となった複数の組を横方向に並列に配置した格好に備える。横搬送機構１２はそれの上流側で供給された遊技盤１または加工治具５の被せられた遊技盤１を矢印Ｘ方向に搬送するローラーコンベアを例示する。横搬送機構１２にはストッパー機構１８が前後搬送機構１３の交差する部分の下流側に設けられる。ストッパー機構１８は横搬送機構１２で搬送されてくる遊技盤１を受け止める動作と、横搬送機構１２で搬送されてくる遊技盤１をやり過ごす動作とを行う。
【００１１】
前後搬送機構１３は横搬送機構１２で搬送された遊技盤１または加工治具５の被せられた遊技盤１が或る１つの加工ステージ１６の前に到達すると、その到達した遊技盤１または遊技盤１に被せられた加工治具５を横搬送機構１２から受け取って矢印Ｙ１方向で示すように加工ステージ１６に搬入したり、加工ステージ１６で穴あけ加工の終了した遊技盤１または加工治具５を加工ステージ１６から矢印Ｙ２方向で示すように横搬送機構１２に搬出したりするチェーンコンベアを例示する。前後搬送機構１３は横搬送機構１２との交差点に配置される前側前後搬送機構１９と加工ステージ１６に配置される後側前後搬送機構２０とに分離された形態である。治具搬送機構１４は前後搬送機構１３で加工ステージ１６から横搬送機構１２の方向に搬出された加工治具５を前後搬送機構１３から受け取って図外の治具回収場所に搬送するローラーコンベアを例示する。
【００１２】
図２を参照し、ルータ加工機１１について説明する。ルータ加工機１１はルータ加工機１１の土台である装置本体２１に工具機構２２、治具保持機構２３、加工対象搭載機構２４を備える。工具機構２２は装置本体２１にＺ駆動源２５で上下方向に垂直移動する工具架台２６を備え、工具架台２６にＸ駆動源２７で左右方向に水平移動する複数の工具取付基体２８を図１の加工ステージ１６と対応する位置に備え、工具取付基体２８にモータのような工具駆動源２９を個別に備える。工具駆動源２９の回転駆動する出力軸にはカッターのような工具１７が個別に取り付けられる。
【００１３】
治具保持機構２３は工具機構２２と別に移動する形態であって、装置本体２１に上記と別のＺ駆動源３１で上下方向に垂直移動する治具架台３２を備え、治具架台３２に電磁石３３を加工ステージ１６と対応する位置に備える。電磁石３３は図１の加工治具５における支持体７を保持・解放するものであることから１つの加工ステージ１６に対し複数個備える。本実施形態では、治具保持機構２３に加工対象搭載機構２４に搭載された図１の遊技盤１や加工治具５を位置決めする位置決めピン３４を設けたことから、位置決めピン３４は治具架台３２に取り付けられ、電磁石３３に形成された中心孔部を経由して電磁石３３よりも下方に突出する。
【００１４】
加工対象搭載機構２４は装置本体２１に複数のＹ駆動源３６で個別に前後方向に水平移動する複数の搭載可動台３７を加工ステージ１６ごとに備え、搭載可動台３７の上にはテーブル３８が加工屑排出や工具逃げのための空間を形成する形態で固定的に設けられる。テーブル３８の上面に加工対象である遊技盤１の裏面が接触した形態で、遊技盤１が意匠盤面２を上に向けた格好でテーブル３８に水平状に搭載される。
【００１５】
図３を参照し、横搬送機構１２と前後搬送機構１３および治具搬送機構１４について説明する。前後搬送機構１３の前側前後搬送機構１９は図外の昇降駆動源で横搬送機構１２よりも下の仮想線で示す下降限度位置と横搬送機構１２よりも上の実線で示す上昇限度位置とに昇降する。前後搬送機構１３の後側前後搬送機構２０は図外の昇降駆動源でテーブル３８よりも下の仮想線で示す下降限度位置とテーブル３８よりも上の実線で示す上昇限度位置とに昇降する。上昇限度位置における前側前後搬送機構１９と上昇限度位置における後側前後搬送機構２０と治具搬送機構１４とのそれぞれの上搬送部は同一面内に配置される。
【００１６】
本実施形態の動作について図４−図６を参照しつつ加工治具５の被せられた遊技盤１を穴あけ加工する方法について説明する。ステップ１０１に示すように、或る１つの種類における最初にルータ加工装置に供給される遊技盤１は、加工治具５の被せられた形態であって、遊技盤１が意匠盤面２を上に向けた格好で横搬送機構１２に上流側で供給される。この供給された遊技盤１は裏面が横搬送機構１２の上搬送部と接触したまま、遊技盤１が横搬送機構１２で矢印Ｘ方向に搬送される。そして、ステップ１０２に示すように、遊技盤１が横搬送機構１２で該当する１つの加工ステージ１６の前に到達すると、ストッパー機構１８が横搬送機構１２の搬送領域の外部から搬送領域の内部に進入して停止する。この進入したストッパー機構１８が横搬送機構１２で搬送されてきた加工治具５の搬送方向先端または遊技盤１の搬送方向先端を受け止めると、遊技盤１が下降限度位置に停止している前側前後搬送機構１９の真上に停止する。
【００１７】
次に、ステップ１０３に示すように、前側前後搬送機構１９が仮想線で示す下降限度位置から上昇し、その上昇途中で前側前後搬送機構１９が加工治具５の被せられた遊技盤１を横搬送機構１２から受け取って浮上支持した後に実線で示す上昇限度位置に停止する。この前側前後搬送機構１９の上昇と並行し、後側前後搬送機構２０も仮想線で示す下降限度位置から上昇して実線で示す上昇限度位置に停止する。その後、ステップ１０４に示すように、前側前後搬送機構１９および後側前後搬送機構２０が加工治具５の被せられた遊技盤１を横搬送機構１２の側から加工ステージ１６に向けて搬送すべく動作を開始し、加工治具５の被せられた遊技盤１が矢印Ｙ１方向に搬送されて加工ステージ１６に到達すると、上記前側前後搬送機構１９および後側前後搬送機構２０の矢印Ｙ１方向の搬送動作が停止する。
【００１８】
加工治具５の被せられた遊技盤１が加工ステージ１６に到達して停止すると、ステップ１０５に示すように加工治具５の位置決め孔６および遊技盤１の位置決め孔３が治具保持機構２３の位置決めピン３４と上下方向で同軸状に対応する。引き続き、後側前後搬送機構２０が矢印で示すように下降すると、その下降途中で加工治具５の被せられた遊技盤１がステップ１０６に示すように後側前後搬送機構２０からテーブル３８に受け取られる。この加工治具５の載せられた遊技盤１が意匠盤面２を上に向けた格好でテーブル３８に受け取られた後に、後側前後搬送機構２０が下降限度位置に停止する。その後、治具保持機構２３の治具架台３２が矢印方向に下降する。また、図示は省略したが、後側前後搬送機構２０の下降と並行し、前側前後搬送機構１９は次の遊技盤１の供給に備えるべく下降して下降限度位置に停止する。
【００１９】
それから、ステップ１０７に示すように、治具保持機構２３の治具架台３２が下降するのに伴い、位置決めピン３４が加工治具５の位置決め孔６および遊技盤１の位置決め孔３に挿入され、遊技盤１および加工治具５がテーブル３８に位置決め搭載された状態となる。これと並行し、電磁石３３と加工治具５の支持体７とが接触する程度に近づいた位置で、治具架台３２の下降が停止する一方、電磁石３３に電力が供給され、電磁石３３が加工治具５の支持体７を磁力で吸着して加工治具５を保持する。その状態において、ステップ１０８に示すように、工具１７が工具駆動源２９で回転駆動し、工具機構２２の工具架台２６が下降する一方、図２のＸ駆動源２７による工具架台２６の左右方向の水平移動とＹ駆動源３６による搭載可動台３７の前後方向の水平移動との協働で、工具１７が加工治具５における図１の開口部８を経由して意匠盤面２から遊技盤１に開口部４を穴あけ加工する。
【００２０】
遊技盤１に必要な個数の開口部４が形成された穴あけ加工が終了すると、ステップ１０９に示すように、加工治具５が電磁石３３の磁力で保持されたまま、治具架台３２が上昇して上昇限度位置に停止する。これと並行し、後側前後搬送機構２０が上昇すると、その上昇途中で穴あけ加工の終了した遊技盤１をテーブル３８から受け取って浮上支持する。
【００２１】
その状態において、後側前後搬送機構２０および前側前後搬送機構１９がステップ１０４に示す矢印Ｙ１方向と逆方向の搬送動作を開始するのに伴い、穴あけ加工の終了した遊技盤１が加工ステージ１６からステップ１０４に示す横搬送機構１２に向けて移動し、穴あけ加工の終了した遊技盤１が横搬送機構１２の真上に到達すると、上記後側前後搬送機構２０の搬送動作および前側前後搬送機構１９の搬送動作が停止する。その後、前側前後搬送機構１９が上昇限度位置から下降すると、その下降途中で穴あけ加工の終了した遊技盤１が後側前後搬送機構２０から横搬送機構１２に受け取られる。この横搬送機構１２に受け取られた穴あけ加工の終了した遊技盤１は横搬送機構１２におけける図１の矢印Ｘ方向の搬送動作で次の加工工程へと搬出される。
【００２２】
次に、前記加工治具５の被せられた遊技盤１と同じ組でそれ以降の加工治具５の被せられていない遊技盤１への穴あけ加工する方法ついて説明する。この方法は、前記加工治具５の被せられた遊技盤１と類似するが、図４−図６におけるステップ１０１−１０５で遊技盤１には加工治具５が被せられておらず、遊技盤１がステップ１０１−１０４を経由してステップ１０５に到達した場合、加工治具５がステップ１０９に示すように治具架台３２で保持されており、その治具架台３２で保持された加工治具５がステップ１０６でテーブル３８に搭載された遊技盤１に対し下降してステップ１０７に示す状態となる点が相違する。
【００２３】
図７を参照し、或る１つの種類における遊技盤１の１組に対する穴あけ加工が終了し、加工治具５を加工ステージ１６からルータ加工機１１の外部に取り出す場合について説明する。前側前後搬送機構１９と後側前後搬送機構２０とが上昇限度位置に停止して治具搬送機構１４と同一面内に配置されている状態において、電磁石３３で加工治具５を保持した治具架台３２が上昇限度位置から下降し、加工治具５が後側前後搬送機構２０に接触するかまたは接触する程度に接近したら、電磁石３３への電力供給が遮断される。それに伴い、加工治具５が自重で後側前後搬送機構２０の上に落下する。その後、後側前後搬送機構２０と前側前後搬送機構１９および治具搬送機構１４が矢印Ｙ２方向への搬送動作を開始すると、加工治具５が実線で示す位置から仮想線で示す位置へと搬送されて治具搬送機構１４の上に取り出される。
【００２４】
本実施形態のルータ加工方法によれば、遊技盤１に形成された意匠盤面２から開口部４を穴あけ加工するので、遊技盤１をルータ加工機１１に供給したりルータ加工機１１から排出したりする場合に意匠盤面２を傷めることが防止できる。また、ルータ加工装置によれば、図１に示すように、ルータ加工機１１の前側に横搬送機構１２を配置し、ルータ加工機１１の加工ステージ１６と横搬送機構１２とにわたり前後搬送機構１３を配置したので、意匠盤面２を上に向けた格好の遊技盤１が横搬送機構１２で搬送されてルータ加工機１１の加工ステージ１６の前に到達すると、当該遊技盤１が前後搬送機構１３で横搬送機構１２から加工ステージ１６に搬送される。よって、遊技盤１が意匠盤面２を上に向けた格好で横搬送機構１２から前後搬送機構１３を経由して加工ステージ１６に供給されるので、その過程において、意匠盤面２が搬送や供給による損傷を受けることはない。ルータ加工機１１が複数の加工ステージ１６を有し、それぞれの加工ステージ１６に遊技盤１を個別に供給する場合においても、複数の遊技盤１を横搬送機構１２で各々の加工ステージ１６に前まで順に搬送し、各加工ステージ１６の前に到達した遊技盤１を各前後搬送機構１３で加工ステージ１６ごとに個別に供給することができるので、複数の遊技盤１を複数の加工ステージ１６のそれぞれに供給する時間が短くなり、生産効率を向上することができる。
【００２５】
図２に示すようにルータ加工機１１に治具保持機構２３を設け、図１に示すように前後搬送機構１３の反対側に治具搬送機構１４を設けたので、ルータ加工機１１での意匠盤面２の剥がれ防止用の加工治具５をルータ加工機１１に供給される遊技盤１のそれぞれに被せる必要がなく、或る１つの種類における遊技盤１の１組に対する穴あけ加工における最初の遊技盤１に加工治具５を被せて加工ステージ１６に供給すればよいので、１つの種類における遊技盤１に対しルータ加工機１１で使用する加工治具５の枚数が少量となり、経済的に有利である。そして、１つの種類における遊技盤１に対しルータ加工機１１での使用が終了した加工治具５は前後搬送機構１３および治具保持機構２３で加工ステージ１６から取り出すことができるので、ルータ加工機１１からの加工治具５の回収も適切に行える。図１に示すように加工治具５が磁性材からなる支持体７を備え、図２に示すように治具保持機構２３が電磁石３３を備えたので、電磁石３３への電力供給・遮断で加工治具５が保持・解放されるので、リンク機構などを使用するハンド機構に比べ、治具保持機構２３での加工治具５の取り扱いが容易である。

BACKGROUND OF THE INVENTION
The present invention relates to a router processing method and apparatus for drilling an opening used in a part attached to a game board in the process of manufacturing a pachinko machine.
[0002]
[Prior art]
In the conventional router processing method, a plate-shaped game board formed with one surface as a design board surface is mounted on the table of the router machine with the design board surface facing down, and then the game board is An opening is made in the game board from the back side (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
JP-A-10-118256 (page 2-3, paragraph number 0003, paragraph number 0010, FIG. 2)
[0004]
[Problems to be solved by the invention]
However, since the conventional example needs to protect the design board surface so as not to be damaged, the hand mechanism descends in a state where a large number of game boards are stacked in the supply section with the design board surface facing down. The uppermost game board stacked is grasped from both sides and lifted, and after the design board surface of the grasped game board is separated from the back surface of the game board below it, the hand mechanism moves sideways and descends to play the game. The board is mounted on the table. For this reason, when processing a plurality of game boards at one time with a single router processing machine, there is a problem that it takes a long time to individually supply a plurality of game boards to a plurality of tables with a hand mechanism, resulting in poor production efficiency. It was.
[0005]
Therefore, the present invention provides a router processing method and apparatus capable of protecting the design board surface and improving the production efficiency by drilling an opening in the game board with a tool from the side of the design board surface. .
[0006]
[Means for Solving the Problems]
A router processing apparatus for forming an opening in a game board as a set of a plurality of game boards according to the present invention includes a first transport mechanism for transporting the game board with the design board surface of the game board facing upward, and a game A processing stage that accepts the design surface of the board facing upward, a second transport mechanism that is arranged separately on the first transport mechanism and the processing stage, and a processing jig that is placed on the game board And a jig transport mechanism for transporting, the game board is transported across the first transport mechanism and the processing stage by the second transport mechanism, and the processing stage is processed by the first game board in a set of game boards. When it is received on the stage, it has a jig holding mechanism that holds the processing jig put on the first game board, and the jig transport mechanism is a jig holding mechanism when processing of a set of game boards is finished Transports processing jigs discharged from By that, since the game board is supplied to the processing stage via a second conveying mechanism from the first conveying mechanism dressed facing upward a design board, in the course of the game board in the transport and supply Damage to the design board surface can be prevented. In addition, even when the router processing machine has multiple processing stages and the game boards are individually supplied to the respective processing stages, the plurality of game boards are sequentially transported to the front of each processing stage by the first transport mechanism. However, since the game board that has reached before each processing stage can be individually supplied to each processing stage by the second transport mechanism , the time for supplying a plurality of game boards to each of the plurality of processing stages is shortened. , Production efficiency can be improved. In addition , when the first game board in a set of game boards having a machining stage is received by the machining stage, a jig holding mechanism for holding a machining jig placed on the first game board is provided, and a jig transport mechanism Since the processing jig discharged from the jig holding mechanism is transported when processing of a set of game boards is completed, a processing jig for preventing the peeling of the design board surface on the router processing machine is supplied to the router processing machine. There is no need to cover each of the game boards to be played, and it is only necessary to put the processing jig on the first game board in the drilling process for one set of game boards of a certain kind and supply it to the processing stage. The number of processing jigs used in the router processing machine is small with respect to the game board in, which is economically advantageous. In addition, since the processing jig that has been used in the router processing machine for one type of game board can be taken out from the processing stage by the second transport mechanism and the jig holding mechanism, the processing jig from the router processing machine can be removed. Equipment can also be collected appropriately.
Further, in the router processing apparatus according to the present invention, if the jig holding mechanism includes an electromagnet that holds and releases the processing jig, the processing jig is held and released by supplying and cutting off power to the electromagnet. Therefore, the processing jig can be easily handled by the jig holding mechanism as compared with a hand mechanism using a link mechanism or the like.

[0008]
The router processing apparatus will be described with reference to FIG. In the present embodiment, the gaming board 1 is a product of a large variety and a small quantity, and when a plurality of gaming boards 1 of one kind are drilled as one set, the first gaming board 1 in the one set is processed. An example will be described in which the tool 5 is supplied to the router processing apparatus in a form in which the tool 5 is mounted, and the subsequent game boards 1 of the same set are supplied to the router processing apparatus in a form in which the processing jig 5 is not mounted. The game board 1 is a plate shape having one surface formed as a design board surface 2 and includes two positioning holes 3 on one diagonal line.
[0009]
The processing jig 5 prevents the design board surface 2 from peeling off around the opening 4 drilled by the tool 17 in the game board 1, and is a recess not shown in the figure formed on a plate-like back surface made of synthetic resin. By fitting the game board 1 into the game board 1, the design board surface 2 of the game board 1 is covered and mounted on the game board 1 so as not to be laterally displaced from the game board 1, while the two positioning holes 6 are positioned in the positioning hole 3 of the game board 1. And at a position corresponding to the coaxial shape. The two positioning holes 6 are central holes of a support 7 made of a magnetic material such as cylindrical iron fixed to the processing jig 5. The processing jig 5 includes an opening 8 that is slightly larger than the opening 4 to be formed in the game board 1.
[0010]
The router processing apparatus includes a router processing machine 11, a lateral transfer mechanism 12 as a first transfer mechanism, a front and rear transfer mechanism 13 as a second transfer mechanism, a jig transfer mechanism 14, and a control device 15. The router processing machine 11 is equipped with a plurality of pairs of processing stages 16 and tools 17 arranged in parallel in the horizontal direction. The horizontal conveyance mechanism 12 illustrates a roller conveyor that conveys the game board 1 supplied on the upstream side thereof or the game board 1 covered with the processing jig 5 in the arrow X direction. The horizontal transport mechanism 12 is provided with a stopper mechanism 18 on the downstream side of the intersecting portion of the front and rear transport mechanism 13. The stopper mechanism 18 performs an operation of receiving the game board 1 transported by the lateral transport mechanism 12 and an operation of passing over the game board 1 transported by the lateral transport mechanism 12.
[0011]
When the game board 1 or the game board 1 covered with the processing jig 5 transported by the lateral transport mechanism 12 arrives in front of a certain processing stage 16, the front-rear transport mechanism 13 reaches the game board 1 or game that has reached it. The processing jig 5 placed on the board 1 is received from the lateral transport mechanism 12 and is loaded into the processing stage 16 as indicated by the direction of the arrow Y1, or the gaming board 1 or the processing jig 5 for which drilling has been completed on the processing stage 16.

[0016]
The operation of the present embodiment will be described with reference to FIGS. 4 to 6 for a method of drilling the game board 1 covered with the processing jig 5. As shown in step 101, the gaming board 1 that is first supplied to the router machining apparatus in a certain type is a form in which the machining jig 5 is covered, and the gaming board 1 faces the design board surface 2 up. Supplied to the horizontal transport mechanism 12 on the upstream side. The game board 1 is transported in the direction of the arrow X by the lateral transport mechanism 12 while the back surface of the supplied game board 1 is in contact with the upper transport portion of the lateral transport mechanism 12. Then, as shown in step 102, when the game board 1 reaches the front of the corresponding processing stage 16 by the lateral transport mechanism 12, the stopper mechanism 18 moves from the outside of the transport area of the lateral transport mechanism 12 to the inside of the transport area. Enter and stop. When the approaching stopper mechanism 18 receives the leading end in the transporting direction of the processing jig 5 transported by the lateral transporting mechanism 12 or the leading end in the transporting direction of the game board 1, the front and rear sides where the game board 1 is stopped at the lower limit position It stops just above the transport mechanism 19.
[0017]
Next, as shown in step 103, the front side front and rear transport mechanism 19 rises from the lower limit position indicated by the phantom line, and the front side front and rear transport mechanism 19 moves the game board 1 covered with the processing jig 5 sideways along the rise. After being received from the transport mechanism 12 and supported by levitation, it stops at the ascending limit position indicated by the solid line. In parallel with the ascent of the front side front and rear transport mechanism 19, the rear side front and rear transport mechanism 20 also rises from the lower limit position indicated by the phantom line and stops at the upper limit position indicated by the solid line. After that, as shown in step 104, the front side front and rear transport mechanism 19 and the rear side front and rear transport mechanism 20 should transport the game board 1 covered with the processing jig 5 from the side of the lateral transport mechanism 12 toward the processing stage 16. When the game board 1 covered with the processing jig 5 is transported in the direction of the arrow Y1 and reaches the processing stage 16, the transport in the direction of the arrow Y1 of the front front / rear transport mechanism 19 and the rear front / rear transport mechanism 20 is started. Operation stops.
[0018]
When the gaming board 1 covered with the processing jig 5 reaches the processing stage 16 and stops, the positioning hole 6 of the processing jig 5 and the positioning hole 3 of the gaming board 1 are moved to the jig holding mechanism 23 as shown in step 105. It corresponds to the positioning pin 34 in the vertical direction in the vertical direction. Subsequently, when the rear side front and rear transport mechanism 20 is lowered as indicated by the arrow, the game board 1 covered with the processing jig 5 is received by the table 38 from the rear side front and rear transport mechanism 20 as shown in step 106 during the lowering. It is. After the game board 1 on which the processing jig 5 is placed is received by the table 38 with the design board surface 2 facing upward, the rear front / rear transport mechanism 20 stops at the lower limit position. Thereafter, the jig mount 32 of the jig holding mechanism 23 is lowered in the arrow direction. Although not shown, in parallel with the lowering of the rear front / rear transport mechanism 20, the front front / rear transport mechanism 19 descends and stops at the lower limit position in preparation for the next game board 1 supply.
[0019]
Then, as shown in step 107, as the jig support 32 of the jig holding mechanism 23 is lowered, the positioning pin 34 is inserted into the positioning hole 6 of the processing jig 5 and the positioning hole 3 of the game board 1, The game board 1 and the processing jig 5 are positioned and mounted on the table 38. In parallel with this, at the position where the electromagnet 33 and the support 7 of the processing jig 5 are in contact with each other, the lowering of the jig mount 32 is stopped, while electric power is supplied to the electromagnet 33 so that the electromagnet 33 is processed. The support 7 of the jig 5 is attracted by a magnetic force to hold the processing jig 5. In this state, as shown in step 108, the tool 17 is rotationally driven by the tool drive source 29, and the tool mount 26 of the tool mechanism 22 is lowered, while the X drive source 27 of FIG. The tool 17 moves from the design board surface 2 to the game board 1 via the opening 8 of FIG. 1 in the processing jig 5 by the cooperation of the horizontal movement and the horizontal movement of the mounting movable table 37 in the front-rear direction by the Y drive source 36. The opening 4 is drilled.
[0020]
When the drilling process in which the required number of openings 4 are formed in the game board 1 is completed, the jig base 32 is raised while the processing jig 5 is held by the magnetic force of the electromagnet 33 as shown in Step 109. To stop at the ascent limit position. In parallel with this, when the rear front / rear transport mechanism 20 is raised, the game board 1 in which the drilling process has been completed is received from the table 38 in the middle of the ascent and supported.
[0021]
In this state, as the rear front / rear transport mechanism 20 and the front front / rear transport mechanism 19 start the transport operation in the direction opposite to the arrow Y1 shown in step 104, the gaming board 1 that has finished drilling is moved from the processing stage 16. When the game board 1 that has moved toward the lateral transport mechanism 12 shown in step 104 and has finished drilling processing has reached directly above the lateral transport mechanism 12, the transport operation of the rear front / rear transport mechanism 20 and the front front / rear transport mechanism 19 are performed. The transport operation stops. Thereafter, when the front side front / rear transport mechanism 19 is lowered from the ascending limit position, the gaming board 1 in which drilling has been completed is received from the rear side front / rear transport mechanism 20 to the lateral transport mechanism 12 during the lowering. The gaming board 1 that has been subjected to the drilling process received by the lateral transport mechanism 12 is transported to the next processing step by the transport operation in the direction of arrow X in FIG.
[0022]
Next, a description will be given of a method of drilling holes in the game board 1 that is not covered with the subsequent processing jig 5 in the same set as the game board 1 that is covered with the processing jig 5. This method is similar to the game board 1 covered with the processing jig 5, but the game board 1 is not covered with the processing jig 5 in steps 101-105 in FIGS. 1 reaches step 105 via steps 101-104, the processing jig 5 is held by the jig base 32 as shown in step 109, and the processing jig held by the jig base 32 is held. 5 is different from the gaming board 1 mounted on the table 38 in step 106 in the state shown in step 107.
[0023]
With reference to FIG. 7, a case will be described in which drilling processing for one set of game boards 1 of a certain type is completed and the processing jig 5 is taken out from the processing stage 16 to the outside of the router processing machine 11. A jig in which the processing jig 5 is held by the electromagnet 33 in a state where the front side front and rear conveyance mechanism 19 and the rear side front and rear conveyance mechanism 20 are stopped at the ascending limit position and are arranged in the same plane as the jig conveyance mechanism 14. When the gantry 32 is lowered from the ascending limit position and the processing jig 5 comes into contact with or approaches the rear side front-rear transport mechanism 20, the power supply to the electromagnet 33 is cut off. Along with this, the processing jig 5 falls on the rear side front-rear transport mechanism 20 by its own weight. Thereafter, when the rear front / rear transport mechanism 20, the front front / rear transport mechanism 19 and the jig transport mechanism 14 start the transport operation in the arrow Y2 direction, the processing jig 5 transports from the position indicated by the solid line to the position indicated by the virtual line. Then, it is taken out onto the jig transport mechanism 14.
[0024]
According to the router processing method of this embodiment, since the opening 4 is drilled from the design board surface 2 formed on the game board 1, the game board 1 is supplied to the router processing machine 11 or discharged from the router processing machine 11. Or the design board surface 2 can be prevented from being damaged. Further, according to the router processing apparatus, as shown in FIG. 1, the horizontal transfer mechanism 12 is disposed on the front side of the router processing machine 11, and the front and rear transfer mechanism 13 extends between the processing stage 16 and the horizontal transfer mechanism 12 of the router processing machine 11. When the game board 1 with the design board surface 2 facing upward is conveyed by the lateral conveyance mechanism 12 and reaches the front of the machining stage 16 of the router processing machine 11, the game board 1 is moved forward and backward. Is transferred from the horizontal transfer mechanism 12 to the processing stage 16. Accordingly, the game board 1 is supplied from the lateral transfer mechanism 12 to the processing stage 16 via the front / rear transfer mechanism 13 with the design board surface 2 facing upward, and in this process, the design board surface 2 is transferred or supplied. There is no damage. Even when the router processing machine 11 has a plurality of processing stages 16 and the game boards 1 are individually supplied to the respective processing stages 16, the plurality of game boards 1 are moved in front of the respective processing stages 16 by the lateral transfer mechanism 12. Since the game boards 1 that have been transported in order and arrived in front of each processing stage 16 can be individually supplied to each processing stage 16 by the respective front and rear transport mechanisms 13, a plurality of game boards 1 can be supplied to the plurality of processing stages 16. The supply time for each of them can be shortened, and the production efficiency can be improved.
[0025]
Since the jig holding mechanism 23 is provided in the router processing machine 11 as shown in FIG. 2 and the jig conveyance mechanism 14 is provided on the opposite side of the front-rear conveyance mechanism 13 as shown in FIG. It is not necessary to put the processing jig 5 for preventing the peeling of the board surface 2 on each of the game boards 1 supplied to the router machine 11, and the first game in the drilling process for one set of the game boards 1 in one kind. Since it is only necessary to cover the board 1 with the processing jig 5 and supply it to the processing stage 16, the number of processing jigs 5 used in the router processing machine 11 is small with respect to one type of game board 1, which is economically advantageous. It is. Since the processing jig 5 that has been used in the router processing machine 11 for one type of game board 1 can be taken out from the processing stage 16 by the front / rear transport mechanism 13 and the jig holding mechanism 23, the router processing machine The processing jig 5 from 11 can be recovered appropriately. As shown in FIG. 1, the processing jig 5 is provided with a support 7 made of a magnetic material, and the jig holding mechanism 23 is provided with an electromagnet 33 as shown in FIG. Since the jig 5 is held and released, it is easier to handle the processing jig 5 with the jig holding mechanism 23 than a hand mechanism using a link mechanism or the like.
