Description

【０００１】
【発明の属する技術分野】
本発明はパチンコ機等の遊技盤に打込まれた釘対の間隔を調整する装置に関する。
【０００２】
【従来の技術】
パチンコ機メーカでは、ルータ加工により遊技盤に入賞口やアウト口等を穴あけし、釘打機により遊技盤に多数の遊技釘や障害釘と呼ばれる釘を打込み、その遊技盤にガイドレール、役物、入賞口、ランプ、飾り等の各種の機能部品を取付けた後、機能部品が正常に動作するか及び釘の中を遊技球が引っ掛らずに通過するか等の検査を行うことにより、遊技盤を製造している。
【０００３】
【発明が解決しようとする課題】
遊技盤の入賞口への入賞を案内する命釘、天釘、袴、袖等と呼ばれる釘対の釘間隔は、パチンコ店の営業上重要な要素であり、その日の営業目的に合せて微妙に調整される。このため、パチンコ機メーカでは釘打機に格納される釘打データ中の釘対の釘間隔を１個の遊技球の直径よりも極僅かに大きい寸法に設定してある。しかし、釘打機は、ＸＹテーブルに遊技盤を位置決め搭載し、釘打機に格納された釘打データの打込位置と順序とに従いＸＹテーブルを平面内で縦横に駆動し、遊技盤の所定位置を釘打機の釘ホルダ機構の真下に移動停止し、釘打機の釘供給部より釘ホルダ機構に供給された釘を釘打機のハンマ機構で遊技盤に打込む構造になっている。そのため、釘打機の各駆動部分における微妙な移動誤差や遊技盤の硬さ等により、釘対の釘間隔が１個の遊技球と略同一寸法又はそれより極僅かな小寸法に打込まれてしまうことがある。そして、検査工程において、釘間隔が１個の遊技球と略同一寸法又はそれより極僅かな小寸法に打込まれた釘対に遊技球を流した場合、遊技球が通る場合と遊技球が引っ掛かる場合とがある。引っ掛かた場合は検査工程で釘間隔を手で広げて調整している。けれども、遊技盤がパチンコ店に収められてから新装又は新規開店までに実施される公安委員会による立入検査において、釘対に遊技球が引っ掛かることがある。この場合には、係る釘間隔をその場で遊技球が引っ掛からないように調整しなければ、新装又は新規開店の営業許可が下りない。
【０００４】
そこで、本発明は釘間隔調整の省力化が図れる遊技機の釘間隔調整装置を提供しようとするものである。
【０００５】
【課題を解決するための手段】
請求項１に係る遊技盤の釘間隔調整装置は、遊技盤の所定位置に１個の遊技球の直径よりも狭い間隔に定められて打込まれた釘対の存在する遊技盤を搭載するテーブルと、テーブルに搭載された上記遊技盤の所定位置における釘対の釘間隔を１個の遊技球の直径よりも広げる拡幅部と、拡幅部をテーブルに搭載された上記遊技盤の所定位置における釘対に対して昇降する駆動機構とを備えたことを特徴とする。請求項２に係る遊技盤の釘間隔調整装置は、遊技盤の所定位置に１個の遊技球の直径よりも狭い間隔に定められて打込まれた釘対の存在する遊技盤を搭載するテーブルと、テーブルに搭載された上記遊技盤の所定位置における釘対の釘間隔を１個の遊技球の直径よりも広げる拡幅部と、拡幅部をテーブルに搭載された上記遊技盤の所定位置における釘対に対して昇降する駆動機構と、テーブルに搭載された上記遊技盤の所定位置における釘対の釘間隔を検出する測定手段と、この測定手段より入力された検出釘間隔と予め定めた基準釘間隔との差により演算した調整値によりテーブルに搭載された上記遊技盤の所定位置における釘対の釘間隔を１個の遊技球の直径よりも広げるように拡幅部を昇降するように駆動機構を駆動する演算手段とを備えたことを特徴とする。請求項１又は請求項２記載に係る遊技盤の釘間隔調整装置において、拡幅部は左右側面が上方より下方に行くに従って徐々に間隔を狭くなる楔状に形成されたり、拡幅部は互いに近づいたり離れたりするように互いに反対方向に移動して釘間隔を広げるための一対のアームを備えたり、テーブルが平面内で縦横に駆動するＸＹテーブルにより形成されたりしてもよい。請求項３記載に係る遊技盤の釘間隔調整装置において、拡幅部の左右側面が拡幅部の左右方向の中心に対する同一角度の斜面として形成され、拡幅部の左右方向の中心がテーブルに搭載された遊技盤の所定位置における釘対の左右方向の中心と上下方向で同軸状に一致されるように、拡幅部が駆動機構により昇降してもよい。請求項２又は請求項３に係る遊技盤の釘間隔調整装置において、測定手段が、テーブルに搭載された遊技盤の所定位置における釘対の釘間隔を検出するための測定部と、測定部をテーブルに搭載された遊技盤の所定位置における釘対に対して昇降する駆動機構とを備えてもよい。請求項７に係る遊技盤の釘間隔調整装置において、測定部が、駆動機構で昇降される支持部と、テーブルに搭載された遊技盤の所定位置における釘対を非接触に取込むための隙間を以って相対峙するように支持部に設けられた二又に別れた先端部と、テーブルに搭載された遊技盤の所定位置における釘対の釘間隔を検出するために先端部の一方に設けられた発光部と、テーブルに搭載された遊技盤の所定位置における釘対の釘間隔を検出するために先端部の他方に設けられた受光部とを備えてもよい。
【０００６】
【発明の実施の形態】
第１実施形態
図１は本発明の第１実施形態の方法を示すフローチャートであって、ステップ１０１の釘打工程において遊技盤の所定位置に釘対を１個の遊技球の直径よりも狭い間隔に打込む。これにより、釘対が遊技盤にマイナスゲージで打込まれる。この第１実施形態の場合、ステップ１０１では遊技盤が釘打機のＸＹテーブルに位置決め搭載され、釘打機がその制御部に予め記憶された当該遊技盤の機種に対応する釘打データより打込位置と順序とを抽出してＸＹテーブルを制御し、遊技盤の所定位置が釘打機の釘ホルダー機構及びハンマ機構の真下に位置決め停止され、釘打機の釘供給部より釘ホルダー機構に供給されて支持された釘をハンマ機構で遊技盤に打込むことにより、１枚の遊技盤に打つべき多数の釘を、遊技盤に１本ずつ自動的に打込む。上記釘打機に格納された釘打データ中において、遊技盤の入賞口に遊技球を誘導するための釘対の釘間隔は、１個の遊技球の直径よりも狭い間隔に定められている。
【０００７】
ステップ１０２の拡幅工程において前記遊技盤に打込まれた釘対の釘間隔を１個の遊技球の直径よりも広げる。
【０００８】
この第１実施形態の方法によれば、釘対を遊技盤に１個の遊技球の直径よりも狭い釘間隔であるマイナスゲージで打込み、その後に、釘対の釘間隔を広げることにより、メーカでの間隔検査工程並びに遊技店での釘間隔調整を容易にすることができる。
【０００９】
第２実施形態
図２は本発明の第２実施形態であって、図２は前述のステップ１０２で用いられる釘間隔調整装置を示す。図２のａ図において、釘間隔調整装置のテーブル１はコンピュータが内蔵された制御部２からの出力により１つの平面の縦横に駆動可能なＸＹテーブルとして形成されている。テーブル１には釘打込みの終了した遊技盤３がその釘の打込まれた側を上に向けて位置決め搭載される。この遊技盤３の所定位置には釘対４が１個の遊技球５の直径Ｄ１よりも狭い間隔Ｄ２に打込まれている（Ｄ１＞Ｄ２）。釘対４を含む釘は、前述の釘打機により、遊技盤３にパチンコ店の島に設置される上の方に向けて約５°程度傾斜するように打込まれるが、図２に示すように、遊技盤３を上方より又は下方より見た場合は遊技盤３に直角に打込まる。
【００１０】
それから、遊技盤３が位置決め搭載されたことを検出する図外の遊技盤センサー、又は、当該遊技盤センサーに代えて作業者の操作でオン動作される図外のマニュアルスイッチの何れかが、遊技盤種別信号と作業開始信号とを、制御部２に出力する。すると、制御部２がその記憶装置に予め格納された当該遊技盤３の機種に対応する作業データ６より作業位置と順序とを抽出してテーブル１を縦方向のＸ方向と横方向のＹ方向とに移動するように制御し、遊技盤３の所定位置が拡幅手段７における楔状の拡幅部８の真下に位置決め停止される。拡幅部８は相対峙する左右側面８ａ，８ｂが上方より下方に行くに従って間隔を狭くすると共に拡幅部８の中心Ｌとの成す角度を同一とした斜面になっている。そして、前記テーブル１の移動停止に際し、制御部２が拡幅部８の中心Ｌと釘対４の釘間隔中心とが上下方向で同軸状に一致するようにテーブル１を制御する。
【００１１】
この状態において、制御部２が拡幅手段７の駆動機構９を制御することにより、駆動機構９が拡幅部８を釘対４に対し昇降させる。拡幅部８は駆動機構９との間で図外のガイド機構により横方向への回転が阻止された形態で駆動機構９により昇降される。この拡幅部８の下降により、図２のｂ図に示すように、拡幅部８の左右側面８ａ，８ｂが釘対４を外側に押し広げ、釘対４が遊技盤３に打込まれた根元部より外側に傾斜し、釘対４の釘間隔が１個の遊技球５の直径Ｄ１よりも大きな間隔Ｄ３に広げられる（Ｄ１＜Ｄ３）。そして、拡幅部８が上昇して釘対４と干渉しない待機位置に戻る。遊技盤３は釘対４を数ヶ所に有するので、拡幅部８が待機位置に戻った後、遊技盤３の次の釘対へのテーブル１の移動と拡幅部８の昇降とが繰返される。
【００１２】
第２実施形態の構造によれば、遊技盤３の所定位置に１個の遊技球５の直径Ｄ１よりも狭い間隔Ｄ２で打込まれた釘対４の釘間隔を、拡幅手段７により、１個の遊技球の直径Ｄ１より大きな間隔Ｄ３に自動的に広げることができる。
【００１３】
第２実施形態の場合、拡幅部８の左右側面８ａ，８ｂが中心Ｌに対する同一角度の斜面になっている。そして、テーブル２の移動停止に際し、拡幅部８の中心Ｌが釘対４の釘間隔中心と上下方向で同軸状に一致されるので、釘対４が下降する拡幅部８により同じ傾斜角度で両側に広がり、その釘対４の広がり形態の見栄えが良くなる。
【００１４】
第３実施形態
図３は本発明の第３実施形態であって、前述の拡幅手段７に代わる拡幅手段１０を示す。この拡幅手段１０は図３のａ図に示すように、駆動機構９の昇降出力端に回転アクチュエータとしてのステッピングモータのようなモータ１１を有し、モータ１１の出力端に楔状の拡幅部８を備える。モータ１１のケーシングは駆動機構９との間で図外のガイド機構により横方向への回転が阻止された形態で駆動機構９により昇降される。釘打ちが終了した遊技盤１は３本の釘よりなる複数の釘対４を有する。
【００１５】
ここで、図３のｂ図において、複数の釘対４を形成する３本の釘の１本ずつに４ａ，４ｂ，４ｃを付し、３つの釘間隔に符号ａ，ｂ，ｃを付す。これらの釘間隔ａ〜ｃは、釘打終了時には、１個の遊技球の直径より狭い間隔である。これらの間隔ａ〜ｃを拡幅手段１０により１個の遊技球の直径よりも広げる場合には、制御部２により制御されるテーブル１の移動と駆動機構９の動作とモータ１１の回転との相互の動作により、拡幅部８が間隔ａ〜ｃそれぞれを広げる。それには３つの間隔ａ〜ｃを１つずつ広げても良いが、例えば、最初に３つの間隔ａ〜ｃのうちの１つを広げ、次に残りの２つの間隔を同時に広げれば、作業時間が最小となる。
【００１６】
図３のｃ図及びｄ図を参照し、最初に広げられる間隔を間隔ａとし、次に同時に広げらる間隔を間隔ｂ，ｃとして、広げる動作について説明する。先ず、ｃ図に示すように、テーブル１の移動により、遊技盤３の所定位置が拡幅部８の真下に位置決め停止される。この場合、拡幅部８の真下には間隔ａが位置しており、ａ図のモータ１１が停止しており、拡幅部８の左右側面８ａ，８ｂが間隔ａを形成する２本の釘４ａ，４ｂに対応している。この状態において、拡幅部８がａ図の駆動機構９の動作によりｃ図の紙面の表側より裏側に向けて下降することにより、拡幅部８が２本の釘４ａ，４ｂを実線示位置より点線示位置へと押し広げる。これにより、ｂ図の間隔ａ，ｂがｄ図の間隔ａ’と大きくなる（ａ＜ａ’）。そして、拡幅部８がａ図の駆動機構９の動作によりｃ図の紙面の裏側より表側に向けて上昇して釘４ａ〜４ｃより上方の待機位置に戻る。
【００１７】
次に、ｄ図に示すように、ａ図のモータ１１が回転し、拡幅部８が回転中心Ｐを中心として一方向に９０°回転した所で停止し、左右側面８ａ，８ｂの何れか１つの側面を釘４ｃと対応させる。この状態において、駆動機構９が動作し、拡幅部８が前記と同様に下降することにより、拡幅部８が釘４ｃを実線示位置より点線示位置へと押し広げる。これにより、ｂ図の間隔ｃがｄ図の間隔，ｂ’，ｃ’と大きくなる（ｂ＜ｂ’、ｃ＜ｃ’）。そして、拡幅部８が駆動機構９の動作により待機位置に戻る。
【００１８】
第４実施形態
第３実施形態では最初に拡幅部８により３つの間隔ａ〜ｃのうちの１つを広げ、次に拡幅部８を９０°回転して残りの２つの間隔を同時に広げたが、拡幅部８の左右側壁８ａ，８ｂと直交するもう１つの側面を左右側壁８ａ，８ｂに類似する傾斜面に形成し、例えば拡幅部８が間隔ａを形成する２つの釘４ａ，４ｂを図３のｃ図の実線示位置より仮想線位置へと押し広げた後、拡幅部８を回転せずにそのままの状態にしておき、テーブル３を移動することで、拡幅部８が間隔ｂ，ｃを形成する釘４ｃを図３のｄ図の実線示位置より仮想線示位置へと押し広げるようにすれば、モータ１１を省略できる。
【００１９】
第５実施形態
図４は本発明の第５実施形態であって、前述の楔状の拡幅部８に代わる拡幅部２０を示す。この拡幅部２０は、図２の駆動機構９の昇降出力端に設けられた二又状の支持部２１を有する。支持部２１は駆動機構９との間で図外のガイド機構により横方向への回転が阻止された形態で駆動機構９により昇降される。支持部２１にはねじ棒２２が回転可能に両端支持されている。ねじ棒２２には２つの雄ねじのようなねじ２３，２４が螺旋方向を互いに反対向きとして同ピッチに形成されている。例えば、一方のねじ２３の螺旋方向が右回りならば、他方のねじ２４の螺旋方向は左回りである。ねじ棒２２のねじ２３，２４のそれぞれには２つのアーム２５，２６を個別にねじ嵌合装着している。ねじ棒２２とアーム２５，２６とのねじ嵌合部分がボルト・ナット機構を構成する。アーム２５，２６は支持部２１にねじ棒２２と並列配置に設けられたガイドレール２７に摺接係合して上下方向の回転を阻止されている。支持部２１には図２の制御部２により制御されるモータ２８が取付けられている。そして、ねじ棒２２がモータ２８により一方向に回転させられることにより、２つのアーム２５，２６がガイドレール２７により回止めされつつねじ２３，２４により互いに反対方向に同じ距離だけ移動する。例えば、ねじ棒２２が或る一方向に回転駆動すると、２つのアーム２５，２６が互いに離れる方向に横移動し、ねじ棒２２が逆の他方向に回転駆動すると、２つのアーム２５，２６が互いに近づく方向に横移動する。
【００２０】
この第５実施形態の構造によれば、図４のａ図に示すように、２つのアーム２５，２６が互いに背中合わせに近づいた状態において、支持部２１が遊技盤３の釘対４に対して下降しｂ図に示す状態となる。この拡幅部２０の下降量は、第２実施形態の拡幅部８の下降量と異なり、ｂ図に示すように、アーム２５，２６の屈曲先端部が釘対４の頭部を軸部側に越えると共に支持部２１とねじ棒２２及びガイドレール２７が釘対４と干渉しない一定距離で良い。その後、ｃ図に示すように、拡幅部２０のモータ２８が一方向に回転し、２つのアーム２５，２６が互いに離れる方向に移動して釘対４を互いに外側に押し広げることにより、釘対４の釘間隔を広げることができる。それから、モータ２８が他方向に回転し、２つのアーム２５，２６がｂ図に示すように互いに近づき、モータ２８の回転が停止した後、支持部２１が上昇しａ図に示すように停止する。
【００２１】
又、この第５実施形態の構造によれば、アーム２５，２６が釘対４の頭部に接触しないようにできるので、釘対４の頭部の見栄えを確保できる。
【００２２】
第６実施形態
図５は本発明の第６実施形態の方法を示すフローチャートであって、前述のステップ１０１に相当するステップ５０１の釘打工程と、前述のステップ１０２に相当するステップ５０３の拡幅工程との間に、ステップ５０２の測定工程を付加し、この測定工程で検出された検出釘間隔により釘対の釘間隔を適切に広げる特徴を有する。
【００２３】
ステップ５０２の測定工程において遊技盤における釘対の釘間隔を検出し、その検出釘間隔と予め定められた基準釘間隔との差により調整値を求める。基準釘間隔は１個の遊技球の直径より狭い間隔として設定された値である。そして、ステップ５０３の拡幅工程において上記求められた調整値により上記遊技盤に打込まれた釘対の釘間隔を１個の遊技球の直径よりも広げる。
【００２４】
この第６実施形態の方法によれば、遊技盤にマイナスゲージに打込まれた釘対の釘間隔をその実測値に応じて広げるので、釘間隔を１個の遊技球の直径よりもより適切に調整することができる。
【００２５】
第７実施形態
図６は本発明の第７実施形態であって、ａ図は前述のステップ５０２及びステップ５０３で用いられる釘間隔調整装置を示し、ｂ図は測定手段３１における発光部３６と受光部３７との詳細を示す。
【００２６】
図６のａ図を参照し、釘間隔調整装置について説明する。釘間隔調整装置は図２のテーブル１と制御部２と拡幅手段７とに加え、測定手段３１と演算手段３２とを新たに備える。テーブル１が釘打込みの終了した遊技盤３を位置決め搭載した状態において、測定手段３１が遊技盤３の所定位置に１個の遊技球の直径よりも狭い間隔で打込まれた釘対４の釘間隔を検出し、演算手段３２が測定手段３１より入力された検出釘間隔と演算手段３２に予め定められた基準釘間隔との差により調整値を求め、拡幅手段７が演算手段３２より入力された調整値により前記遊技盤３に打込まれた釘対４の釘間隔を１個の遊技球の直径よりも広げる。
【００２７】
第７実施形態の場合、遊技盤種別信号と作業開始信号とが制御部２に入力されると、制御部２がテーブル１に搭載された遊技盤３の機種に対応する作業データ６に基づきテーブル１と測定手段３１の測定部３３と測定手段３１の駆動機構３４とを制御する。
【００２８】
制御部２がテーブル１を制御することにより、テーブル１に位置決め搭載された遊技盤３の釘対４が存在する所定位置が測定部３３の真下に位置決め停止する。この状態において、制御部２が駆動機構３４を制御することにより、駆動機構３４が測定部３３を遊技盤３の釘対４に対し昇降させる。この測定部３３が下降位置に停止する毎に釘対４の釘間隔を検出して演算手段３２に出力する。
【００２９】
測定部３３は駆動機構３４の昇降出力端に設けられた二又状の支持部３５を有する。支持部３５は駆動機構３４との間で図外のガイド機構により横方向への回転が阻止された形態で駆動機構３４により昇降される。支持部３５の二又に別れた先端部には１組の発光部３６と受光部３７とを個別に有する。発光部３６と受光部３７とはそれらの間に形成された隙間に測定対象である釘対４を非接触に取込む。
【００３０】
図６のｂ図に示すように、発光部３６は多数の発光素子３６ａを釘対４の釘間隔に沿う方向に一定間隔を以って一列配置に有し、受光部３７は発光素子３６ａと同数なる多数の受光素子３７ａを同発光素子３６ａと同一間隔を以って相対峙した一列配置に有する。そして、発光素子３６ａのそれぞれは制御部２からの指示によりレーザ光のような測定光Ｓを対向する受光素子３７ａのそれぞれに向けて照射することにより、発光素子３６ａより照射された測定光Ｓの一部が釘対４により遮断され、一列中の受光素子３７ａのうちで釘対４と対応する部分における複数の受光素子３７ａの受光量がそれ以外の受光素子３７ａの受光量より減少する。受光部３７は受光量の減少した複数の受光素子３７ａの間隔を釘対４の検出釘間隔として変換して演算手段３２に出力する。
【００３１】
演算手段３２は、検出釘間隔と基準釘間隔との差を演算し、その演算した差により調整値を求め、この求めた調整値と検出釘間隔と検査位置とを対応付けた調整値情報として記憶する。そして、測定部３３が上昇して釘対４と干渉しない待機位置に戻る。遊技盤３は釘対４を数ヶ所に有するので、測定部３３が待機位置に戻った後、遊技盤３の次の釘対４へのテーブル１の移動と測定手段３１の測定と演算手段３２の演算・記憶とが繰返される。遊技盤３に打込まれた釘対４の全部に対する測定が終了すると、制御部２が拡幅手段７に作業開始を指示する。
【００３２】
制御部２が、拡幅手段７への作業開始を指示する際、演算手段３２より調整値情報を抽出して記憶する。そして、制御部２は、テーブル１を１つの平面内の縦横に移動し、釘対４の存在する所定位置が拡幅部８の真下に位置したらテーブル１を停止する。この場合、制御部２は、演算手段３２に定めらた基準釘間隔と同じ基準釘間隔の中心位置と演算手段３２からの調整値情報より抽出した検出釘間隔の中心位置との差を位置補正値として演算し、この位置補正値により拡幅部８の中心Ｌと釘対４の釘間隔における左右方向の中心とが上下方向で同軸状に一致されるように、テーブル１の移動停止を制御する。そして、制御部２による制御により、拡幅部８が遊技盤３の釘対４に対して下降し釘対４の釘間隔を広げた後、拡幅部８が上昇する。この拡幅部８の下降量は、制御部２に記憶された調整値情報における検査位置に応じた調整値により検査位置毎に変わる。即ち、或る検査位置における検出釘間隔が小さければ、拡幅部８の下降量を多くし、その或る検査位置に対応する釘対４に対する拡幅部８の挿入量を多くし、係る釘対４の釘間隔の広げ幅を大きくする。逆に、或る検査位置における検出釘間隔が大きければ、拡幅部８の下降量を少なくし、その或る検査位置に対応する釘対４に対する拡幅部８の挿入量を少なくし、係る釘対４の釘間隔の広げ幅を小さくする。
【００３３】
第７実施形態の構造によれば、遊技盤３の所定位置に１個の遊技球の直径よりも狭い間隔で打込まれた釘対４の釘間隔を検出し、その検出釘間隔と基準釘間隔との差による調整値を求め、その調整値により前記遊技盤３に打込まれた釘対４の釘間隔を１個の遊技球の直径よりも適切に広げることができる。
【００３４】
また、この第７実施形態の構造によれば、テーブル１の移動停止に際し、拡幅部８の中心と釘対４の中心とを上下方向で同軸状に一致しており、釘対４が下降する拡幅部８により同じ傾斜角度で両側に広がるので、釘対４の広がった形態の見栄えが良くなる。
【００３５】
第２，３，７実施形態ではテーブル１が縦横に移動し、拡幅手段７或いは測定手段３１が昇降したが、テーブル１を固定式とし、拡幅手段７或いは測定手段３１が縦横移動と昇降との両方を行うようにしても良く、又は、テーブル１を昇降式、又は、テーブル１を縦横移動と昇降との両方を行うようにしても良い。
【００３６】
第７実施形態では発光素子３６ａと受光素子３７ａとが一列配置された線状アレイを用いたが、発光素子３６ａと受光素子３７ａとが格子配置された面状アレイを用いた画像処理方式でも良い。
【００３７】
第２，３，７実施形態において、テーブル１を釘打機のＸＹテーブルと兼用し、釘打機に拡幅手段７或いは測定手段３１及び演算手段３２を付加しても良い。
【００３８】
前記作業データ６は釘打データより作成しても良い。
【００３９】
【発明の効果】

DETAILED DESCRIPTION OF THE INVENTION
First embodiment
FIG. 1 is a flowchart showing a method according to the first embodiment of the present invention, in which a nail pair is driven into a predetermined position of the game board at a narrower interval than the diameter of one game ball in the nail driving process of step 101. As a result, the nail pair is driven into the game board with a minus gauge. In the case of the first embodiment, in step 101, the game board is positioned and mounted on the XY table of the nailing machine, and the nailing machine is driven by nailing data corresponding to the model of the game board previously stored in the control unit. The XY table is controlled by extracting the insertion position and order, and the predetermined position of the game board is stopped under the nail holder mechanism and hammer mechanism of the nailing machine, and the nail supply part of the nailing machine is moved to the nail holder mechanism. By driving the supplied and supported nails into the game board by the hammer mechanism, a number of nails to be hit on one game board are automatically driven into the game board one by one. In the nail driving data stored in the nailing machine, the nail interval between the nail pairs for guiding the game balls to the winning hole of the game board is set to be narrower than the diameter of one game ball. .
[0007]
In the widening step of step 102, the nail interval between the pair of nails driven into the game board is made larger than the diameter of one game ball.
[0008]
According to the method of the first embodiment, the nail pair is driven into the game board with a minus gauge that is a nail interval narrower than the diameter of one game ball, and then the nail interval of the nail pair is widened. It is possible to facilitate the interval inspection process at the nail and the nail interval adjustment at the amusement store.
[0009]
Second embodiment
FIG. 2 shows a second embodiment of the present invention, and FIG. 2 shows a nail interval adjusting device used in step 102 described above. In FIG. 2a, the table 1 of the nail interval adjusting device is formed as an XY table that can be driven vertically and horizontally on one plane by an output from a control unit 2 in which a computer is built. On the table 1, the game board 3 in which nails have been driven is positioned and mounted with the nail-injected side facing up. A nail pair 4 is driven into a predetermined position of the game board 3 at a distance D2 narrower than the diameter D1 of one game ball 5 (D1> D2). The nail including the nail pair 4 is driven into the game board 3 so as to incline about 5 ° toward the upper side installed on the island of the pachinko shop by the above-described nailing machine, as shown in FIG. Thus, when the game board 3 is viewed from above or from below, the game board 3 is driven at a right angle.
[0010]
Then, either a gaming board sensor (not shown) for detecting that the gaming board 3 is positioned and mounted, or a manual switch (not shown) that is turned on by an operator's operation in place of the gaming board sensor, The board type signal and the work start signal are output to the control unit 2. Then, the control unit 2 extracts the work position and order from the work data 6 corresponding to the model of the game board 3 stored in advance in the storage device, and the table 1 is moved in the vertical X direction and the horizontal Y direction. The predetermined position of the game board 3 is positioned and stopped just below the wedge-shaped widened portion 8 in the widening means 7. The widened portion 8 has an inclined surface with the same angle formed with the center L of the widened portion 8 while the interval between the right and left side surfaces 8a, 8b facing each other decreases from the upper side to the lower side. When the movement of the table 1 is stopped, the control unit 2 controls the table 1 so that the center L of the widened portion 8 and the center of the nail interval of the nail pair 4 coincide with each other in the vertical direction.
[0011]
In this state, the control unit 2 controls the drive mechanism 9 of the widening means 7 so that the drive mechanism 9 raises and lowers the widened portion 8 relative to the nail pair 4. The widening portion 8 is lifted and lowered by the drive mechanism 9 in a form in which rotation in the lateral direction is prevented by a guide mechanism (not shown) with the drive mechanism 9. 2B, the left and right side surfaces 8a and 8b of the widened portion 8 push the nail pair 4 outward, and the nail pair 4 is driven into the game board 3. The nail interval between the nail pairs 4 is expanded to a distance D3 larger than the diameter D1 of one game ball 5 (D1 <D3). Then, the widened portion 8 rises and returns to the standby position where it does not interfere with the nail pair 4. Since the game board 3 has the nail pairs 4 at several places, the movement of the table 1 to the next nail pair of the game board 3 and the raising / lowering of the wide part 8 are repeated after the wide part 8 returns to the standby position.
[0012]
According to the structure of the second embodiment, the nail interval between the pair of nails 4 that is driven into the predetermined position of the game board 3 with the interval D2 narrower than the diameter D1 of one game ball 5 is It can be automatically expanded to a distance D3 larger than the diameter D1 of the individual game balls.
[0013]
In the case of the second embodiment, the left and right side surfaces 8a and 8b of the widened portion 8 are inclined surfaces having the same angle with respect to the center L. When the table 2 stops moving, the center L of the widened portion 8 coincides with the center of the nail interval of the nail pair 4 in the vertical direction so that the widened portion 8 where the nail pair 4 descends has the same inclination angle on both sides. And the appearance of the spread form of the nail pair 4 is improved.
[0014]
Third embodiment
FIG. 3 shows a third embodiment of the present invention, and shows a widening means 10 that replaces the aforementioned widening means 7. As shown in FIG. 3 a, the widening means 10 has a motor 11 such as a stepping motor as a rotary actuator at the elevation output end of the drive mechanism 9, and a wedge-shaped widening portion 8 at the output end of the motor 11. Prepare. The casing of the motor 11 is moved up and down by the drive mechanism 9 in a form in which rotation in the lateral direction is prevented between the casing and the drive mechanism 9 by a guide mechanism (not shown). The game board 1 which has finished nailing has a plurality of nail pairs 4 composed of three nails.
[0015]
Here, in FIG. 3 b, 4 a, 4 b, 4 c are attached to each of the three nails forming the plurality of nail pairs 4, and the symbols a, b, c are attached to the three nail intervals. These nail intervals a to c are intervals smaller than the diameter of one game ball at the end of nail driving. When these intervals a to c are increased by the widening means 10 beyond the diameter of one game ball, the movement of the table 1 controlled by the control unit 2, the operation of the drive mechanism 9, and the rotation of the motor 11 are mutually controlled. By the above operation, the widened portion 8 widens the intervals a to c. For this purpose, the three intervals a to c may be expanded one by one. For example, if one of the three intervals a to c is first expanded and then the remaining two intervals are expanded simultaneously, the working time is increased. Is minimized.
[0016]
With reference to FIG. 3 and FIG. 3D, the operation of widening the first widening interval as the interval a and then the simultaneous widening intervals as the intervals b and c will be described. First, as shown in FIG. C, the position of the predetermined position of the game board 3 is stopped just below the widened portion 8 by the movement of the table 1. In this case, the interval a is located directly below the widened portion 8, the motor 11 in FIG. A is stopped, and the two nails 4a, the left and right side surfaces 8a, 8b of the widened portion 8 form the interval a. It corresponds to 4b. In this state, the widened portion 8 is lowered from the front side to the back side of the paper surface of FIG. C by the operation of the driving mechanism 9 of FIG. Push it to the indicated position. As a result, the intervals a and b in FIG. B become larger than the interval a ′ in FIG. D (a <a ′). Then, the widening portion 8 rises from the back side of the paper surface of FIG. C toward the front side by the operation of the driving mechanism 9 of FIG. A and returns to the standby position above the nails 4a to 4c.
[0017]
Next, as shown in FIG. D, the motor 11 in FIG. A rotates and stops when the widened portion 8 rotates 90 ° in one direction around the rotation center P, and either one of the left and right side surfaces 8a, 8b. One side is made to correspond with nail 4c. In this state, the drive mechanism 9 operates and the widened portion 8 is lowered in the same manner as described above, so that the widened portion 8 pushes the nail 4c from the solid line position to the dotted line position. As a result, the interval c in FIG. B increases to the intervals in FIG. D, b ′ and c ′ (b <b ′, c <c ′). Then, the widened portion 8 returns to the standby position by the operation of the drive mechanism 9.
[0018]
Fourth embodiment
In the third embodiment, one of the three intervals a to c is first widened by the widened portion 8, and then the widened portion 8 is rotated by 90 ° to simultaneously widen the remaining two intervals. 3 is formed on the inclined surface similar to the left and right side walls 8a and 8b. For example, the two nails 4a and 4b in which the widened portion 8 forms the interval a are shown in FIG. After extending the position shown by the solid line from the position indicated by the solid line to the virtual line position, the widened portion 8 is left as it is without rotating, and the table 3 is moved so that the widened portion 8 forms the gaps b and c. The motor 11 can be omitted by pushing 4c from the solid line position in FIG. 3d to the virtual line position.
[0019]
Fifth embodiment
FIG. 4 shows a fifth embodiment of the present invention, and shows a widened portion 20 that replaces the wedge-shaped widened portion 8 described above. The widened portion 20 has a bifurcated support portion 21 provided at the lift output end of the drive mechanism 9 of FIG. The support portion 21 is moved up and down by the drive mechanism 9 in a form in which the support portion 21 is prevented from rotating in the lateral direction by a guide mechanism (not shown). A screw rod 22 is rotatably supported by the support portion 21 at both ends. The screw rod 22 is formed with screws 23 and 24 like two male screws at the same pitch with the spiral directions being opposite to each other. For example, if the spiral direction of one screw 23 is clockwise, the spiral direction of the other screw 24 is counterclockwise. Two arms 25 and 26 are individually screwed and attached to the screws 23 and 24 of the screw rod 22, respectively. The screw fitting portion between the screw rod 22 and the arms 25 and 26 constitutes a bolt / nut mechanism. The arms 25 and 26 are slidably engaged with a guide rail 27 provided in parallel with the screw rod 22 on the support portion 21 and are prevented from rotating in the vertical direction. A motor 28 controlled by the control unit 2 in FIG. 2 is attached to the support unit 21. When the screw rod 22 is rotated in one direction by the motor 28, the two arms 25 and 26 are moved by the same distance in the opposite directions by the screws 23 and 24 while being rotated by the guide rail 27. For example, when the screw rod 22 is rotationally driven in one direction, the two arms 25 and 26 are laterally moved away from each other, and when the screw rod 22 is rotationally driven in the opposite direction, the two arms 25 and 26 are rotated. Move sideways toward each other.
[0020]
According to the structure of the fifth embodiment, as shown in FIG. 4 a, the support portion 21 is against the nail pair 4 of the game board 3 in a state where the two arms 25 and 26 are close to each other. Lowers to the state shown in FIG. The descending amount of the widened portion 20 is different from the descending amount of the widened portion 8 of the second embodiment, and as shown in FIG. B, the bent tip portions of the arms 25 and 26 have the heads of the nail pair 4 on the shaft side. It may be a fixed distance so that the support 21, the screw rod 22, and the guide rail 27 do not interfere with the nail pair 4. Thereafter, as shown in FIG. 3c, the motor 28 of the widened portion 20 rotates in one direction, the two arms 25, 26 move away from each other, and the nail pair 4 is pushed outward to expand the nail pair. 4 nail intervals can be widened. Then, the motor 28 rotates in the other direction, the two arms 25 and 26 approach each other as shown in FIG. B, and after the rotation of the motor 28 stops, the support portion 21 rises and stops as shown in FIG. .
[0021]
Further, according to the structure of the fifth embodiment, the arms 25 and 26 can be prevented from coming into contact with the heads of the nail pair 4, so that the appearance of the heads of the nail pair 4 can be ensured.
[0022]
Sixth embodiment
FIG. 5 is a flowchart showing a method according to the sixth embodiment of the present invention. Between the nailing process of step 501 corresponding to step 101 described above and the widening process of step 503 corresponding to step 102 described above. The measurement process of step 502 is added, and the nail interval of the nail pair is appropriately widened by the detection nail interval detected in this measurement process.
[0023]
In the measurement process of step 502, the nail interval of the nail pair on the game board is detected, and an adjustment value is obtained from the difference between the detected nail interval and a predetermined reference nail interval. The reference nail interval is a value set as an interval narrower than the diameter of one game ball. Then, in the widening process of step 503, the nail interval between the nail pairs driven into the game board is expanded more than the diameter of one game ball by the obtained adjustment value.
[0024]
According to the method of the sixth embodiment, the nail interval of the nail pair driven into the minus gauge on the game board is increased according to the actual measurement value, so that the nail interval is more appropriate than the diameter of one game ball. Can be adjusted.
[0025]
Seventh embodiment
FIG. 6 shows a seventh embodiment of the present invention, in which FIG. 6a shows the nail interval adjusting device used in the above-mentioned steps 502 and 503, and FIG. 6b shows the relationship between the light emitting unit 36 and the light receiving unit 37 in the measuring means 31. Show details.
[0026]
The nail interval adjusting device will be described with reference to FIG. In addition to the table 1, the control unit 2, and the widening means 7 in FIG. 2, the nail interval adjusting device newly includes a measuring means 31 and a computing means 32. The nail of the nail pair 4 in which the measuring means 31 is driven into a predetermined position of the game board 3 at a smaller interval than the diameter of one game ball in a state where the table 1 is mounted with the game board 3 in which the nail driving has been completed. The interval is detected, the calculation means 32 obtains an adjustment value based on the difference between the detected nail interval input from the measurement means 31 and the reference nail interval predetermined in the calculation means 32, and the widening means 7 is input from the calculation means 32. With the adjusted value, the distance between the nail pairs 4 driven into the game board 3 is made larger than the diameter of one game ball.
[0027]
In the case of the seventh embodiment, when the game board type signal and the work start signal are input to the control unit 2, the control unit 2 sets the table based on the work data 6 corresponding to the model of the game board 3 mounted on the table 1. 1, the measuring unit 33 of the measuring means 31 and the drive mechanism 34 of the measuring means 31 are controlled.
[0028]
When the control unit 2 controls the table 1, the predetermined position where the nail pair 4 of the game board 3 positioned and mounted on the table 1 is positioned and stopped immediately below the measurement unit 33. In this state, the control unit 2 controls the drive mechanism 34 so that the drive mechanism 34 raises and lowers the measurement unit 33 relative to the nail pair 4 of the game board 3. Each time the measuring unit 33 stops at the lowered position, the nail interval of the nail pair 4 is detected and output to the computing means 32.
[0029]
The measurement unit 33 includes a bifurcated support unit 35 provided at the elevation output end of the drive mechanism 34. The support portion 35 is moved up and down by the drive mechanism 34 in such a manner that the support portion 35 is prevented from rotating in the lateral direction by a guide mechanism (not shown). A pair of light emitting part 36 and light receiving part 37 are individually provided at the bifurcated tip of the support part 35. The light emitting unit 36 and the light receiving unit 37 take in the nail pair 4 as a measurement object in a non-contact manner in a gap formed between them.
[0030]
As shown in FIG. 6b, the light emitting unit 36 has a large number of light emitting elements 36a arranged in a line at a constant interval in the direction along the nail interval of the nail pair 4, and the light receiving unit 37 is connected to the light emitting element 36a. The same number of light receiving elements 37a are arranged in a row in which the light emitting elements 36a are opposed to each other with the same interval. Each of the light emitting elements 36a irradiates the measuring light S such as a laser beam toward each of the opposing light receiving elements 37a according to an instruction from the control unit 2, so that the measuring light S emitted from the light emitting element 36a is irradiated. A part of the light receiving elements 37a is blocked by the nail pair 4, and the light receiving amount of the plurality of light receiving elements 37a in the portion corresponding to the nail pair 4 in the light receiving elements 37a in the row is smaller than the light receiving amount of the other light receiving elements 37a. The light receiving unit 37 converts the interval between the plurality of light receiving elements 37 a having a reduced amount of received light as the detection nail interval of the nail pair 4 and outputs it to the computing means 32.
[0031]
The calculating means 32 calculates a difference between the detected nail interval and the reference nail interval, obtains an adjustment value based on the calculated difference, and provides adjustment value information associating the obtained adjustment value with the detected nail interval and the inspection position. Remember. Then, the measuring unit 33 moves up and returns to the standby position where it does not interfere with the nail pair 4. Since the game board 3 has the nail pairs 4 at several places, after the measuring unit 33 returns to the standby position, the table 1 is moved to the next nail pair 4 on the game board 3, the measurement means 31 measures, and the calculation means 32. The calculation and storage are repeated. When the measurement for all of the nail pairs 4 driven into the game board 3 is completed, the control unit 2 instructs the widening means 7 to start work.
[0032]
When the control unit 2 instructs the widening means 7 to start work, the adjustment value information is extracted from the calculation means 32 and stored. Then, the control unit 2 moves the table 1 vertically and horizontally in one plane, and stops the table 1 when a predetermined position where the nail pair 4 exists is located directly below the widened portion 8. In this case, the control unit 2 corrects the difference between the center position of the reference nail interval that is the same as the reference nail interval determined by the calculation means 32 and the center position of the detected nail interval extracted from the adjustment value information from the calculation means 32. The table 1 is calculated as a value, and the movement stop of the table 1 is controlled by this position correction value so that the center L of the widened portion 8 and the center in the left-right direction in the nail interval of the nail pair 4 are coaxially matched in the vertical direction. . Then, under the control of the control unit 2, the widened portion 8 descends with respect to the nail pair 4 of the game board 3 and widens the nail interval of the nail pair 4, and then the widened portion 8 rises. The descending amount of the widening portion 8 changes for each inspection position depending on the adjustment value corresponding to the inspection position in the adjustment value information stored in the control unit 2. That is, if the detection nail interval at a certain inspection position is small, the descending amount of the widened portion 8 is increased, and the insertion amount of the widened portion 8 with respect to the nail pair 4 corresponding to the certain inspection position is increased. Increase the width of the nail gap. Conversely, if the detected nail interval at a certain inspection position is large, the descending amount of the widened portion 8 is reduced, and the insertion amount of the widened portion 8 with respect to the nail pair 4 corresponding to the certain inspection position is reduced. 4. Decrease the width of nail gap 4
[0033]
According to the structure of the seventh embodiment, the nail interval of the nail pair 4 that is driven at a predetermined position on the game board 3 at a smaller interval than the diameter of one game ball is detected, and the detected nail interval and the reference nail are detected. An adjustment value based on the difference from the distance can be obtained, and the distance between the nail pairs 4 driven into the game board 3 can be appropriately expanded from the diameter of one game ball by the adjustment value.
