【０００１】
【発明の属する技術分野】
本発明はパチンコ機などの遊技盤に打ち込まれた釘の姿勢を調整する装置に関する。
【０００２】
【従来の技術】
従来の遊技盤の釘調整装置は、遊技盤に遊技に使用される１個の球の直径よりも狭い間隔で打ち込まれた釘の釘間隔つまり釘の位置を測定し、測定した検出釘間隔と予め定めた基準釘間隔つまり基準位置との差により調整値を演算し、演算した調整値により上記釘を遊技盤に打ち込まれた根元部から横に傾けるように釘の姿勢を変更して、遊技盤に打ち込まれた釘の間隔を広げている（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、前記従来例は釘の位置の測定と調整とを別々の手段で行う構成であるため、測定と調整との繰り返し作業で、生産効率が悪いという問題点があった。
【０００５】
そこで、本発明は遊技盤に打ち込まれた釘の位置を測定しながら釘を遊技盤に打ち込まれた根元部から横に傾けるように釘の姿勢を変更することで、生産効率を向上することができる遊技盤の釘調整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】
本発明に係る遊技盤の釘調整装置は、装置本体の上部に平面内の縦横方向に移動可能に設けられるテーブルと、テーブルの移動およびテーブルへの遊技盤の搭載に邪魔にならないように装置本体の上部に設けられた架台と、架台の上部に設けられた基盤と、テーブルの上面に対し所定角度で傾斜した基盤の上面に取り付けられた全体昇降機構と、基盤を上下方向に貫通するように全体昇降機構に設けられた全体昇降体と、全体昇降体の基盤から下方に突出した下端部に設けられたロータリーインデックスと、ロータリーインデックスにおける回転テーブルの下面に設けられた取付体と、ロータリーインデックスの回転中心と同軸上に存在する取付体の中心から左右両側に分かれて取付体の下部に設けられた左右の固定ベースと、左右の固定ベースに個別に移動可能に設けられた左右の可動ベースと、左右の固定ベースに個別に組み込まれて左右の可動ベースの移動距離を個別に測定する左右の測定機器と、左右の可動ベースに個別に設けられた左右の個別昇降機構と、左右の個別昇降機構に個別に設けられた左右の個別昇降体と、左右の個別昇降体に個別に設けられた左右の調整子とを備えたことを最も主要な特徴とする。本発明に係る遊技盤の釘調整装置によれば、遊技盤に打ち込まれた釘が上に向けられるように、遊技盤がテーブルに搭載され、テーブルが移動して遊技盤の調整対象位置が左右の調整子の下に停止された状態において、左右の調整子が全体昇降機構と左右の可動ベースと測定機器および左右の個別昇降機構の相互の動作に伴い釘の位置を測定しながら当該釘を遊技盤に打ち込まれた根元部から横に傾けることができ、ロータリーインデックスの動作で左右の調整子が遊技盤の前面に対し斜めに打ち込まれた調整対象たる釘と平行するようになる。
【０００７】
【発明の実施の形態】
図１−図９は一実施形態であって、図１は釘調整装置の測定調整機構１０を模式的に示し、図２は調整子２７の外観を示し、図３は調整子２７と釘１２との関係を示し、図４は釘調整装置の外観を示し、図５−図７は調整動作を示し、図８および図９は再調整動作を示す。
【０００８】
図４を参照し、釘調整装置について説明する。釘調整装置の制御装置１に格納されたコンピューターの記憶装置には作業データーが記憶されている。作業データーは遊技盤１１の機種と調整対象位置と調整作業順序と基準距離との関係を規定したデーターマップやデーターテーブルのような調整知識である。釘調整装置の土台である装置本体２の上部にはテーブル３が図外のモーターを動力とするＸＹ駆動機構で１つの平面の縦横であるＸＹ方向に水平に移動可能に設けられる。テーブル３にはテーブル３に形成された図外の位置決めピンと遊技盤１１に加工基準として形成された図外の位置決め孔とが互いに嵌め合わせられることで遊技盤１１が位置決め搭載される。テーブル３に供給される遊技盤１１には遊技盤１１の前面である意匠盤面の球の飛び交う遊技領域に球の流れや球の飛び交いを作るための遊技釘や障害釘と呼ばれる多数本の釘１２が既に所定寸法の高さに打ち込まれている。
【０００９】
装置本体２の上部には架台４が固定される。架台４はテーブル３のＸＹ方向への移動およびテーブル３への遊技盤１１の搭載に邪魔にならないような空間を備える。空間の上部を覆う基盤５の前半部はテーブル３の上面（遊技盤１１搭載面）に対し所定角度で傾斜した後傾状（装置本体２からの基盤５の高さが前側から後側に行くにしたがって徐々に高くなる状態）である。基盤５の前半部における上面には全体昇降機構６が取り付けられる。全体昇降機構６は測定調整機構１０を全体的に基盤５の前半部における上面に対し直角に昇降するためのモーターを動力とする構造になっている。全体昇降機構６の出力部分である図外の全体昇降体は基盤５を上下方向に貫通し、全体昇降体の基盤５から下方に突出した下端部には電気エネルギーで回転角度割出動作するロータリーインデックス（回転テーブルアクチュエータ）７が設けられる。ロータリーインデックス７における回転テーブルの下面には横長な取付体９が固定される。取付体９の下部には測定調整機構１０が設けられる。
【００１０】
図１を参照し、測定調整機構１０について説明する。測定調整機構１０は電気エネルギーで動作する左右の測定移動体２１を備える。左右の測定移動体２１は例えば固定ベースと非鉄金属製の可動テーブルとの間にリニアサーボモーターおよび光学式リニアスケール（可動テーブルの直線的な移動距離を光で測定し、その測定距離を電気信号として出力する）のような測定機器２２を組み込んだリニアモーターテーブルに構成されており、リニアモーターテーブルの固定ベースである測定移動体２１の固定ベース２３が図４のロータリーインデックス７の回転中心と同軸上に存在する取付体９の中心Ｌ１から左右両側に等距離の位置に固定される。リニアモーターテーブルの可動ベースである測定移動体２１の可動ベース２４のそれぞれには左右の調整子２７を個別に昇降するための左右の個別昇降機構２５が別々に設けられる。個別昇降機構２５の出力部分である個別昇降体２６には左右の調整子２７が個別に固定される。この左右の調整子２７の先端部に設けられた釘接触部３１が調整対象である釘１２の胴体１３に接触する姿勢は、釘接触部３１の下端縁３１ａまたは上端縁３１ｂが釘１２の遊技盤１１から釘１２の頭部１４における頂点までの高さＨの１／２の位置Ｐに接触する。釘の位置を調整する場合、釘接触部３１の下端縁３１ａまたは上端縁３１ｂは釘１２と擦れるので、釘１２に擦過傷が付かないように例えば弧状面のような形状になっている。
【００１１】
図２を参照し、調整子２７について説明する。調整子２７は先端部の平面視弧状の釘接触部３１、後端部の角棒状の取付基部３２、釘接触部３１と取付基部３２との間に逃部３３を備えた直線棒状である。釘接触部３１は釘を調整する場合、図３のａ図にも示すように釘接触部３１が釘１２における胴体１３の外周面の一部を周方向中心部に接触し、図３のｂ図にも示すように釘接触部３１が釘１２における頭部１４の外周縁の一部と全面的に接触する曲率（釘接触部３１の曲率半径と頭部１４の曲率半径とが同一寸法）を有する。また、釘接触部３１は図７に示すように複数の釘１２が互いに接近して打ち込まれた連釘における釘間隔に非接触に挿入される厚さである。取付基部３２には調整子２７を図１の個別昇降体２６に取り付けるためのボルトを挿入する取付孔３４が形成される。逃部３３は図５に示すように釘１２の胴体１３が釘接触部３１と接触した場合に釘１２の頭部１４を非接触に取り込む窪みである。
【００１２】
本実施形態の調整動作について説明する。制御装置１が電力供給で起動した状態において、釘打ち込みの終了した遊技盤１１がその釘１２の打ち込まれた側を上に向けてテーブル３に位置決め搭載される。この遊技盤１１の調整対象である所定位置には一対の釘１２が１個の球の直径よりも狭い間隔に打ち込まれている。遊技盤１１に打ち込まれた釘１２は、釘打ち込みを実行する図外の釘打機により、遊技盤１１にパチンコ店の島と呼ばれるような遊技機設置設備に設置される上の方に向けて図５に示すように約５度程度傾斜するように打ち込まれるが、図６に示すように遊技盤１１を上方よりまたは下方より見た場合は遊技盤１１に直角に打ち込まれている。
【００１３】
そして、遊技盤１１がテーブル３に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、または、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いずれかが、遊技盤機種信号と作業開始信号とを制御装置１に出力すると、制御装置１が作業データーの調整対象位置と調整作業順序とによりテーブル３をＸ方向とＹ方向とに移動するようにＸＹ駆動機構を制御し、遊技盤１１の調整対象位置である所定位置が測定調整機構１０における左右の調整子２７の真下に位置決め停止される。左右の調整子２７は釘接触部３１が一対の釘１２の釘間隔にそれぞれの釘１２に非接触で上方から挿入されるように左右方向で互いに近づいた状態になる。この場合、調整子２７の対向間隔の中心と取付体９の中心Ｌ１とが互いに同軸上に位置する。
【００１４】
その後、前記テーブル３の移動停止に際して制御装置１が調整子２７の対向間隔の中心と全体昇降装置の中心と一対の釘１２の対向間隔中心と取付体９の中心Ｌ１とが互いに同軸上に位置するようにテーブル３を制御する。その状態において、制御装置１が全体昇降機構６及び左右の測定移動体２１を制御することにより、全体昇降機構６が取付体９を下降する。この取付体９の下降は左右の調整子２７の釘接触部３１と釘１２の胴体１３とが左右方向で対向するとともに調整子２７の逃部３３と釘１２の頭部１４とが左右方向で対向する位置で停止する。その後、制御装置１が左右の測定移動体２１を制御することにより、左右の調整子２７が互いに離れる方向に移動する。
【００１５】
図５および６を参照し、測定移動体２１による調整動作について説明する。図５および図６では図１の個別昇降機構２５および個別昇降体２６の図示を省略してある。
【００１６】
図５において、ａ図に示すように、遊技盤１１に三角形における３つの頂点に釘１２が個別に打ち込まれている状態において、三角形の底辺側で左右に相対峙する一対の釘１２における釘間隔を調整する場合について説明する。この場合、取付体９はロータリーインデックス７の動作で調整対象たる一対の釘１２と平行する方向に横長となるように配置される（取付体９は矢印Ａと直交する方向に横長となる）。ｂ図に示すように、取付体９の中心Ｌ１と調整対象である一対の釘１２による釘間隔の中心とが同軸上となり、左右の調整子２７の釘接触部３１が双方の釘１２に接触しないように一対の釘１２の釘間隔に挿入されて釘１２の胴体１３と左右方向で対向し、左右の調整子２７の逃部３３が釘１２の頭部１４と左右方向で対向した状態になっている。
【００１７】
その状態において、左右の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げない程度の力で矢印で示す互いに離れる方向に横移動するのに伴い、左右の測定機器２２が取付体９の中心Ｌ１からの測定距離信号を制御装置１に出力し、左右の調整子２７における釘接触部３１が左右の釘１２の胴体１３に接触すると、上記可動ベース２４の移動が停止する。この場合、図１に示す釘接触部３１の下端縁３１ａが釘１２の高さＨの１／２の位置Ｐと対向している。その後、制御装置１は左右の調整子２７が左右の釘１２と接触したと判断して左右の測定機器２２から制御装置１に入力されている測定距離信号に相当する測定距離を演算する。この演算される測定距離は左右の測定機器２２ごとの前記中心Ｌ１からの距離として左右個別に演算される。その理由は遊技盤１１の物性や釘１２の物性あるいは機械の応答性などが遊技盤１１や釘１２および機械動作時の個々で異なることから、遊技盤１１に打ち込まれている左右の釘１２の中心からの距離が設計値と微妙に異なる場合があるからである。
【００１８】
その後、左右の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げ得る力で再び矢印で示す互いに離れる方向に横移動するのに伴い、制御装置１が左右の測定機器２２から制御装置１に入力されてくる測定距離信号に相当する中心Ｌ１からの測定距離を演算するとともに当該演算した測定距離を基準釘間隔の１／２の基準距離（中心Ｌ１からの基準距離）と左右個別に比較する。そして、演算した左右の測定距離と基準距離とが一致するごとに、制御装置１が上記左右の測定移動体２１の矢印方向への移動を個別に停止する。この左右の可動ベース２４の釘１２を曲げ得る力による横移動によって、一対の釘１２が左右の調整子２７により仮想線で示すように遊技盤１１に打ち込まれた根元部より外側に個別に傾けられる。つまり、一対の釘１２が遊技盤１１に打ち込まれた姿勢から基準位置となるように姿勢変更され、一対の釘１２における釘間隔が基準間隔に調整される。このように一対の釘１２における釘間隔が基準間隔に調整されたところで、前記左右の可動ベース２４の矢印方向への移動が停止する。それから、制御装置１が左右の測定移動体２１を矢印とは逆方向へ互いに近づく方向に移動し、左右の調整子２７が最も接近した元の位置に復帰したら、制御装置１が前記左右の測定移動体２１の逆方向への移動を停止した後、制御装置１が全体昇降機構６を上昇して次の調整作業位置への測定調整動作を準備する。
【００１９】
図６は、ａ図に示すように、遊技盤１１に三角形における３つの頂点に釘１２が個別に打ち込まれている状態において、三角形の底辺側の左右に相対峙する一方の釘１２と三角形の頂点の釘１２とにおける釘間隔を調整する場合であって、取付体９はロータリーインデックス７の動作で調整対象たる一対の釘１２と平行する方向に横長となるように配置される（取付体９は矢印Ｂと直交する方向に横長となる）。よって、ｂ図に示すように、左右の調整子２７および一対の釘１２が取付体９の中心Ｌ１と一致する傾きである形態が図５のｂ図と相違する。図６の調整動作は前述した図５の調整動作と同じである。
【００２０】
図５および図６では左右の調整子２７で左右の釘１２それぞれを傾けることで釘間隔を調整したが、いずれか一方の調整子２７でいずれか一方の釘１２を傾けて釘間隔を調整してもよい。
【００２１】
図７は連釘を構成する右側の釘１２を傾けることで当該右の釘１２と左の釘１２とによる釘間隔を調整する場合であって、図４の制御装置１が右の調整子２７が左の調整子２７よりも低くなるように右の個別昇降機構２５を動作する。その後、右の釘接触部３１が調整対象である右の釘１２と左の釘１２とに接触しないように一対の釘１２の釘間隔に挿入されて右の釘１２の頭部１４と左右方向で対向した状態となる。その状態において、右の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げない程度の力で矢印で示す互いに離れる方向に横移動するのに伴い、右の測定機器２２が取付体９の中心Ｌ１からの測定距離信号を制御装置１に出力し、右の調整子２７の釘接触部３１が右の釘１２の頭部１４に接触すると、上記可動ベース２４の移動が停止し、制御装置１は右の測定機器２２から制御装置１に入力されている測定距離信号に相当する中心Ｌ１からの測定距離を演算する。
【００２２】
その後、右の可動ベース２４が制御装置１からの出力で釘１２を曲げ得る力で再び矢印で示す方向に移動し、右の測定機器２２から制御装置１に入力されている測定距離が基準距離と一致すると、制御装置１が上記右の測定移動体２１の矢印方向への移動を停止することによって、右の釘１２が右の調整子２７により仮想線で示すように遊技盤１１に打ち込まれた根元部より外側に傾けられ、右の釘１２と左の釘１２とにおける釘間隔が基準釘間隔に調整された後、制御装置１が右の測定移動体２１や右の個別昇降機構２５および全体昇降機構６を右の調整子２７が元の位置に復帰停止するように制御する。
【００２３】
第１実施形態の構造によれば、遊技盤１１に打ち込まれた釘１２の釘間隔を測定しながら拡幅するので、生産効率を向上することができる。また、測定調整機構１０が左右の調整子２７を個別に移動するとともに左右の調整子の移動距離を個別に測定するので、遊技盤１１に打ち込まれた釘１２の釘間隔を測定しながら拡幅し、生産効率を向上することができる。また、測定調整機構１０が左右の調整子２７を個別に移動するとともに左右の調整子２７の移動距離を個別に測定する左右の測定移動体２１を備えるので、釘間隔を構成する一対の釘１２それぞれを傾けて釘間隔を調整することができる。また、測定調整機構１０が左右の測定移動体２１と、左右の調整子２７を左右の測定移動体２１に対し個別に昇降する左右の個別昇降機構２５とを備えれば、左右の調整子２７のいずれか一方だけで釘間隔を調整することができる。また、調整子２７が釘１２の胴体１３および頭部１４の双方に接触可能な釘接触部３１と、釘接触部３１が釘１２の胴体１３と接触した場合に当該釘１２の頭部１４を逃げる逃部３３とを備えたので、調整子２７で釘１２の胴体１３または釘１２の頭部１４のいずれかを利用して釘間隔を調整することができる。また、釘接触部３１が釘１２の頭部１４における外周縁の一部と全面的に接触する弧状に形成されているので、釘接触部３１が傾ける釘１２の胴体１３または釘１２の頭部１４のいずれも適切に保持することができる。また、釘接触部３１が遊技盤１１に打ち込まれた釘１２で構成された連釘の間に挿入し得る厚さに形成されているので、連釘での釘間隔も適切に調整することができる。
【００２４】
次に、図８および図９を参照し、遊技盤１１の物性や釘１２の物性あるいは機械の応答性などが遊技盤１１や釘１２および機械動作時の個々で異なることに起因し、実際の調整作業では調整時における釘の傾き不足や傾き過ぎが発生することがあるので、それに対処する再調整について説明する。
【００２５】
この再調整は前述の図５−図７における調整動作とは別にまたは図５−図７における調整動作の後段に引き続いて実行することができる。ここでは、図５−図７における調整動作の後段に引き続いて再調整動作を行う場合を例として説明する。例えば、図５において、左右の調整子２７が釘１２を曲げ得る力で横移動した後、制御装置１が左右の測定移動体２１を矢印の逆方向へと互いに近づく方向に移動し、左右の調整子２７が一対の釘１２から互いに離れたところで、制御装置１が左右の測定移動体２１の逆方向への横移動を停止する。
【００２６】
その状態において、再び、制御装置１が左右の測定移動体２１の可動ベース２４を釘１２の曲がらない程度の力で矢印で示す互いに離れる方向に横移動し、左右の調整子２７の釘接触部３１が左右の釘１２の胴体１３に接触し、上記可動ベース２４の移動が停止するのに伴い、制御装置１は左右の測定機器２２から入力されている測定距離信号で測定距離を演算する。この再演算によって、図５での調整後における左右の釘１２による弾性や機械の応答遅れが原因で中心Ｌ１からの調整された測定距離が不正確になっていないかを検証する。この検証の結果、調整後における左右の釘１２の測定距離が基準距離と一致する場合は、再調整作業を行う必要がないので、制御装置１は左右の測定移動体２１を矢印と逆方向へと互いに近づく方向に移動し、左右の調整子２７が互いに最も接近した元の位置に復帰したところで、制御装置１が左右の測定移動体２１の逆方向への移動を停止する。
【００２７】
上記検証の結果、調整後における左右の釘１２の測定距離が基準距離と不一致の場合は、次のように再調整を行う。具体的には、検証した測定距離が基準距離よりも小さい場合は、調整後における左右の釘１２が図５の仮想線示位置から実線示位置の方へ少し戻った場合であるので、検証位置から左右の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げ得る力で再び矢印で示す互いに離れる方向に横移動するのに伴い、制御装置１が左右の測定機器２２から入力されてくる測定距離信号による中心Ｌ１からの測定距離を演算するとともに当該演算した測定距離を中心Ｌ１からの基準距離と左右個別に比較する。そして、演算した左右の測定距離と基準距離とが一致するごとに、制御装置１が上記左右の測定移動体２１の矢印方向への移動を個別に停止する。
【００２８】
上記検証の結果、検証した測定距離が基準距離よりも大きい場合は、調整後における左右の釘１２が仮想線示位置よりもさらに外側に傾いた場合である。このように調整後の釘間隔が広すぎた場合には、例えば図８や図９に示すような２通りの修正方法がある。
【００２９】
図８において、点線で示した釘１２は図５や図６に実線で示した釘１２と同じ調整前の形態であり、仮想線で示した左の釘１２は図５や図６に仮想線で示した釘１２と同じ調整後の形態であり、実線で示した左の釘１２は遊技盤１１の物性や釘１２の物性あるいは機械の応答性などが原因で基準距離よりも外側に傾き過ぎた形態である。図８に示す再調整は右の調整子２７で左の釘１２を再調整し、左の調整子２７で右の釘１２を再調整する方法である。この再調整法においては、左の釘１２が広がり過ぎていることから、当該左の釘１２を右の調整子２７で調整する場合を例として説明する。前述した検証後において、制御装置１が全体昇降機構６を上昇し、左右の調整子２７が左右の釘１２を上方に超えたら上記全体昇降機構６の上昇を停止した後、制御装置１が左右の測定移動体２１の可動ベース２４を互いに左側に移動し、制御装置１が演算した測定距離から右の調整子２７の釘接触部３１が左の釘１２の頭部１４を左側に超える位置を把握し、その超える位置で制御装置１が上記左右の測定移動体２１の左側への移動を停止する。
【００３０】
その後、制御装置１が全体昇降機構６を下降し、右の調整子２７の釘接触部３１の上端縁３１ｂが左の釘１２の位置Ｐ（１／２Ｈ）と対向する位置で、制御装置１が上記全体昇降機構６の下降を停止する。その後、右の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げない程度の力で矢印で示す方向に横移動するのに伴い、右の測定機器２２が取付体９の中心Ｌ１からの測定距離信号を制御装置１に出力し、右の調整子２７における釘接触部３１が左の釘１２の胴体１３に接触すると、上記可動ベース２４の移動が停止する。この場合、釘接触部３１の上端縁３１ｂが釘１２の高さＨの１／２の位置Ｐと対向している。その後、制御装置１は右の調整子２７が左の釘１２と接触したと判断して右の測定機器２２から制御装置１に入力されている測定距離信号に相当する中心Ｌ１からの測定距離を演算し、当該演算した測定距離と右の中心Ｌ１からの基準距離との差を演算する。その後、右の測定移動体２１の可動ベース２４が制御装置１からの上記差の演算に基づく出力で左の釘１２を曲げ得る力で再び矢印で示す方向に横移動するのに伴い、制御装置１が右の測定機器２２から制御装置１に入力されてくる測定距離信号に相当する中心Ｌ１からの測定距離を演算するとともに当該演算した測定距離を中心Ｌ１からの基準距離と比較する。そして、演算した測定距離と基準距離とが一致すると、制御装置１が上記右の測定移動体２１の矢印方向への移動を停止する。これによって、右の釘１２が実線示位置から仮想線示位置へと内側に傾けられる。つまり、広がり過ぎた右の釘１２が基準位置となるように姿勢変更される。このように広がり過ぎた右の釘１２が正確に再調整されたら、前記右の可動ベース２４の矢印方向への移動が停止する。それから、制御装置１が右の測定移動体２１を矢印とは逆方向に移動し、左右の調整子２７が最も接近した元の位置に復帰したら、制御装置１が前記右の測定移動体２１の逆方向への移動を停止した後、制御装置１が全体昇降機構６を上昇して次の調整作業位置への測定調整動作を準備する。
【００３１】
図９において、点線で示した釘１２は図５や図６に実線で示した釘１２と同じ調整前の形態であり、仮想線で示した左の釘１２は図５や図６に仮想線で示した釘１２と同じ調整後の形態であり、実線で示した左の釘１２は遊技盤１１の物性や釘１２の物性あるいは機械の応答性などが原因で基準距離よりも外側に傾き過ぎた形態である。図９に示す再調整は右の調整子２７で右の釘１２を再調整し、左の調整子２７で左の釘１２を再調整する方法である。この再調整法においては、左の釘１２が広がり過ぎていることから、当該左の釘１２を左の調整子２７で調整する場合を例として説明する。前述した検証後において、制御装置１が全体昇降機構６を上昇し、左右の調整子２７が左右の釘１２を上方に超えたら上記全体昇降機構６の上昇を停止した後、制御装置１が左右の測定移動体２１の可動ベース２４を互いに離れる方向に移動し、制御装置１が演算した測定距離から左右の調整子２７の釘接触部３１が左右の釘１２の頭部１４を左側または右側に超える位置を把握し、その超える位置で制御装置１が上記左右の測定移動体２１の移動を停止する。
【００３２】
その後、制御装置１が全体昇降機構６を下降し、左の調整子２７の釘接触部３１が左の釘１２の胴体１３と対向する位置で、制御装置１が上記全体昇降機構６の下降を停止する。その後、左の測定移動体２１の可動ベース２４が制御装置１からの出力で釘１２を曲げない程度の力で矢印で示す方向に横移動するのに伴い、左の測定機器２２が取付体９の中心Ｌ１からの測定距離信号を制御装置１に出力し、左の調整子２７における釘接触部３１よりも上部背面が左の釘１２の頭部１４に接触すると、上記可動ベース２４の移動が停止する。その後、制御装置１は左の調整子２７が左の釘１２と接触したと判断して左の測定機器２２から制御装置１に入力されている測定距離信号に相当する測定距離（中心Ｌ１からの距離）を釘１２の高さＨの１／２の位置Ｐと釘１２の頭部１４との関係から補正演算し、当該補正演算した測定距離と右の中心Ｌ１からの基準距離との差を演算する。その後、左の測定移動体２１の可動ベース２４が制御装置１からの上記差の演算に基づく出力で左の釘１２を曲げ得る力で再び矢印で示す方向に横移動するのに伴い、制御装置１が左の測定機器２２から制御装置１に入力されてくる測定距離信号に相当する中心Ｌ１からの測定距離を補正演算するとともに当該補正演算した測定距離を中心Ｌ１からの基準距離と比較する。そして、補正演算した測定距離と基準距離とが一致すると、制御装置１が上記左の測定移動体２１の矢印方向への移動を停止する。これによって、右の釘１２が実線示位置から仮想線示位置へと内側に傾けられる。つまり、広がり過ぎた右の釘１２が基準位置となるよう姿勢変更される。このように広がり過ぎた右の釘１２が正確に再調整されたら、前記右の可動ベース２４の矢印方向への移動が停止する。それから、制御装置１が右の測定移動体２１を矢印とは逆方向に移動し、左右の調整子２７が最も接近した元の位置に復帰したら、制御装置１が前記右の測定移動体２１の逆方向への移動を停止した後、制御装置１が全体昇降機構６を上昇して次の調整作業位置への測定調整動作を準備する。
【００３３】

[0008]
The nail adjusting device will be described with reference to FIG. Work data is stored in the storage device of the computer stored in the control device 1 of the nail adjustment device. The work data is adjustment knowledge such as a data map or a data table that defines the relationship between the model of the game board 11, the position to be adjusted, the adjustment work order, and the reference distance. A table 3 is provided on the upper part of the apparatus main body 2 which is the base of the nail adjusting apparatus so as to be horizontally movable in the XY directions which are the length and width of one plane by an XY drive mechanism powered by a motor (not shown). The gaming board 11 is positioned and mounted on the table 3 by fitting a positioning pin (not shown) formed on the table 3 and a positioning hole (not shown) formed on the gaming board 11 as a processing reference. The game board 11 supplied to the table 3 includes a large number of nails 12 called game nails and obstacle nails for making a flow of balls and a ball jump in the game area where the balls of the design board surface, which is the front surface of the game board 11, fly. Has already been driven to a predetermined height.
[0009]
A gantry 4 is fixed to the upper part of the apparatus main body 2. The gantry 4 has a space that does not interfere with the movement of the table 3 in the X and Y directions and the mounting of the game board 11 on the table 3. The front half of the base 5 that covers the upper part of the space is tilted at a predetermined angle with respect to the upper surface of the table 3 (the surface on which the game board 11 is mounted) (the height of the base 5 from the device body 2 goes from the front side to the rear side). It becomes a state where it becomes gradually higher). The entire lifting mechanism 6 is attached to the upper surface of the front half of the base 5. The entire elevating mechanism 6 has a structure in which a motor for elevating and lowering the measurement adjustment mechanism 10 as a whole at a right angle with respect to the upper surface of the front half of the base 5 is used as power. An overall lifting body (not shown), which is an output portion of the overall lifting mechanism 6, penetrates the base 5 in the vertical direction, and a rotary that indexes the rotation angle with electric energy at the lower end protruding downward from the base 5 of the overall lifting body. An index (rotary table actuator) 7 is provided. A horizontally long attachment body 9 is fixed to the lower surface of the rotary table in the rotary index 7. A measurement adjustment mechanism 10 is provided below the attachment body 9.
[0010]
The measurement adjustment mechanism 10 will be described with reference to FIG. The measurement adjustment mechanism 10 includes left and right measurement moving bodies 21 that operate with electric energy. The left and right measurement moving bodies 21 are, for example, a linear servo motor and an optical linear scale (measured with a light between a fixed base and a non-ferrous metal movable table). 4), and the fixed base 23 of the measurement moving body 21, which is a fixed base of the linear motor table, is coaxial with the rotation center of the rotary index 7 in FIG. It is fixed at equidistant positions on the left and right sides from the center L1 of the mounting body 9 existing above. Each of the movable bases 24 of the measurement moving body 21 which is a movable base of the linear motor table is provided with a left and right individual lifting mechanism 25 for lifting the left and right adjusters 27 individually. Left and right adjusters 27 are individually fixed to an individual lifting body 26 that is an output portion of the individual lifting mechanism 25. The position in which the nail contact portion 31 provided at the tip of the right and left adjusters 27 contacts the body 13 of the nail 12 to be adjusted is such that the lower end edge 31a or the upper end edge 31b of the nail contact portion 31 is a game of the nail 12. It contacts a position P that is ½ of the height H from the board 11 to the apex of the head 14 of the nail 12. When adjusting the position of the nail, the lower end edge 31a or the upper end edge 31b of the nail contact portion 31 is rubbed against the nail 12, and thus has a shape such as an arcuate surface so that the nail 12 is not scratched.
[0011]
The adjuster 27 will be described with reference to FIG. The adjuster 27 is in the form of a straight bar having a nail contact portion 31 having an arcuate shape at the front end portion, a square bar-like attachment base portion 32 at the rear end portion, and a relief portion 33 between the nail contact portion 31 and the attachment base portion 32. When the nail contact portion 31 adjusts the nail, the nail contact portion 31 contacts a part of the outer peripheral surface of the body 13 of the nail 12 with the central portion in the circumferential direction as shown in FIG. As shown in the figure, the curvature at which the nail contact portion 31 is in full contact with a part of the outer peripheral edge of the head 14 in the nail 12 (the radius of curvature of the nail contact portion 31 and the radius of curvature of the head 14 are the same dimension). Have Further, the nail contact portion 31 has a thickness that is inserted in a non-contact manner into a nail interval in a continuous nail in which a plurality of nails 12 are driven close to each other as shown in FIG. An attachment hole 34 for inserting a bolt for attaching the adjuster 27 to the individual elevating body 26 of FIG. 1 is formed in the attachment base 32. As shown in FIG. 5, the relief portion 33 is a recess that takes in the head portion 14 of the nail 12 in a non-contact manner when the body 13 of the nail 12 comes into contact with the nail contact portion 31.
[0012]
The adjustment operation of this embodiment will be described. In a state in which the control device 1 is activated by power supply, the game board 11 in which the nail driving has been completed is positioned and mounted on the table 3 with the nail 12 driven side facing up. A pair of nails 12 are driven into a predetermined position, which is an adjustment target of the game board 11, at an interval narrower than the diameter of one sphere. The nail 12 driven into the game board 11 is installed on a game machine installation facility called a pachinko shop island on the game board 11 by an unillustrated nailing machine that executes nailing. As shown in FIG. 5, the game board 11 is driven so as to incline about 5 degrees. However, as shown in FIG. 6, when the game board 11 is viewed from above or below, the game board 11 is driven at a right angle.
[0013]
Then, either a gaming board sensor (not shown) that detects that the gaming board 11 is positioned and mounted on the table 3 or a manual switch (not shown) that is turned on by an operator's operation instead of the gaming board sensor. However, when the game board model signal and the work start signal are output to the control device 1, the control device 1 moves the table 3 in the X direction and the Y direction according to the adjustment target position of the work data and the adjustment work order. The drive mechanism is controlled, and the predetermined position, which is the position to be adjusted on the game board 11, is positioned and stopped just below the left and right adjusters 27 in the measurement adjustment mechanism 10. The left and right adjusters 27 are close to each other in the left-right direction so that the nail contact portions 31 are inserted into the nails between the pair of nails 12 without contact with the nails 12 from above. In this case, the center of the opposing interval of the adjuster 27 and the center L1 of the attachment body 9 are located on the same axis.
[0014]
Thereafter, when the movement of the table 3 is stopped, the control device 1 positions the center of the opposing spacing of the adjuster 27, the center of the entire lifting device, the opposing spacing center of the pair of nails 12 and the center L1 of the mounting body 9 to be coaxial with each other. The table 3 is controlled as follows. In this state, the control device 1 controls the entire elevating mechanism 6 and the left and right measurement moving bodies 21 so that the entire elevating mechanism 6 descends the attachment body 9. When the mounting body 9 is lowered, the nail contact portion 31 of the left and right adjuster 27 and the body 13 of the nail 12 face each other in the left-right direction, and the relief portion 33 of the adjuster 27 and the head 14 of the nail 12 are left-right. Stop at the opposite position. Thereafter, the control device 1 controls the left and right measurement moving bodies 21 so that the left and right adjusters 27 are moved away from each other.
[0015]
With reference to FIGS. 5 and 6, the adjustment operation by the measurement moving body 21 will be described. 5 and 6, illustration of the individual lifting mechanism 25 and the individual lifting body 26 of FIG. 1 is omitted.
[0016]
In FIG. 5, as shown in FIG. 5A, when the nails 12 are individually driven into three vertices of the triangle on the game board 11, the nail interval between the pair of nails 12 facing the left and right on the bottom side of the triangle The case of adjusting is described. In this case, the attachment body 9 is disposed so as to be horizontally long in a direction parallel to the pair of nails 12 to be adjusted by the operation of the rotary index 7 (the attachment body 9 is horizontally long in a direction orthogonal to the arrow A). As shown in FIG. b, the center L1 of the attachment body 9 and the center of the nail interval between the pair of nails 12 to be adjusted are coaxial, and the nail contact portions 31 of the left and right adjusters 27 are in contact with both nails 12. The nail 12 is inserted between the pair of nails 12 so as to face the body 13 of the nail 12 in the left-right direction, and the relief portion 33 of the left and right adjusters 27 faces the head 14 of the nail 12 in the left-right direction. It has become.
[0017]
In this state, as the movable bases 24 of the left and right measurement moving bodies 21 laterally move in the directions away from each other as indicated by arrows with a force that does not bend the nail 12 with the output from the control device 1, the left and right measurement instruments 22 are moved. Outputs a measurement distance signal from the center L1 of the mounting body 9 to the control device 1, and when the nail contact portion 31 of the left and right adjusters 27 contacts the body 13 of the left and right nails 12, the movement of the movable base 24 stops. To do. In this case, the lower end edge 31 a of the nail contact portion 31 shown in FIG. 1 faces the position P that is ½ of the height H of the nail 12. Thereafter, the control device 1 determines that the left and right adjusters 27 are in contact with the left and right nails 12 and calculates a measurement distance corresponding to the measurement distance signal input from the left and right measurement devices 22 to the control device 1. The calculated measurement distance is calculated separately as the distance from the center L1 for each of the left and right measuring devices 22. The reason is that the physical properties of the game board 11, the physical properties of the nail 12, the responsiveness of the machine, etc. are different between the game board 11, the nail 12 and the machine operation, so that the left and right nails 12 driven into the game board 11 This is because the distance from the center may be slightly different from the design value.
[0018]
After that, as the movable base 24 of the left and right measurement moving bodies 21 laterally moves in the direction away from each other as indicated by arrows again with a force capable of bending the nail 12 by the output from the control device 1, the control device 1 moves to the left and right measuring devices. 22 calculates a measurement distance from the center L1 corresponding to the measurement distance signal input to the control device 1 and calculates the calculated measurement distance to a reference distance ½ of the reference nail interval (reference distance from the center L1). Compare with left and right separately. Each time the calculated left and right measurement distances match the reference distance, the control device 1 individually stops the movement of the left and right measurement moving bodies 21 in the arrow directions. Due to the lateral movement of the left and right movable bases 24 by the force that can bend the nails 12, the pair of nails 12 are individually tilted outward from the root portion driven into the game board 11 by the left and right adjusters 27 as indicated by phantom lines. It is done. That is, the posture is changed from the posture in which the pair of nails 12 are driven into the game board 11 to the reference position, and the nail interval between the pair of nails 12 is adjusted to the reference interval. As described above, when the nail interval between the pair of nails 12 is adjusted to the reference interval, the movement of the left and right movable bases 24 in the arrow direction stops. Then, when the control device 1 moves the left and right measurement moving bodies 21 in directions opposite to each other in the direction opposite to the arrows and returns to the original position where the left and right adjusters 27 are closest, the control device 1 detects the left and right measurement bodies. After stopping the movement of the moving body 21 in the reverse direction, the control device 1 raises the entire lifting mechanism 6 and prepares a measurement adjustment operation to the next adjustment work position.
[0019]
As shown in FIG. 6A, in the state where the nails 12 are individually driven into the three vertices of the triangle on the game board 11, one of the nails 12 and the triangle In this case, the mounting body 9 is arranged so as to be horizontally long in a direction parallel to the pair of nails 12 to be adjusted by the operation of the rotary index 7 (the mounting body 9). Is horizontally long in the direction orthogonal to the arrow B). Therefore, as shown in FIG. 5b, the configuration in which the left and right adjusters 27 and the pair of nails 12 are inclined so as to coincide with the center L1 of the attachment body 9 is different from that in FIG. The adjustment operation in FIG. 6 is the same as the adjustment operation in FIG. 5 described above.
[0020]
5 and 6, the nail interval is adjusted by tilting the left and right nails 12 with the left and right adjusters 27, but either nail 12 is tilted with either one of the adjusters 27 to adjust the nail interval. May be.
[0021]
FIG. 7 shows a case where the nail interval between the right nail 12 and the left nail 12 is adjusted by tilting the right nail 12 constituting the continuous nail. The control device 1 in FIG. The right individual elevating mechanism 25 is operated so that is lower than the left adjuster 27. After that, the right nail contact portion 31 is inserted into the nail interval of the pair of nails 12 so as not to contact the right nail 12 and the left nail 12 to be adjusted, and the head 14 of the right nail 12 and the left and right direction. It will be in the state which opposed. In this state, as the movable base 24 of the right measurement moving body 21 laterally moves away from each other as indicated by an arrow with a force that does not bend the nail 12 with the output from the control device 1, the right measurement device 22 is moved. Outputs a measurement distance signal from the center L1 of the mounting body 9 to the control device 1, and when the nail contact portion 31 of the right adjuster 27 contacts the head 14 of the right nail 12, the movement of the movable base 24 is performed. The control device 1 stops, and calculates the measurement distance from the center L1 corresponding to the measurement distance signal input to the control device 1 from the right measurement device 22.
[0022]
Thereafter, the right movable base 24 is moved again in the direction indicated by the arrow with a force capable of bending the nail 12 by the output from the control device 1, and the measurement distance input from the right measurement device 22 to the control device 1 is the reference distance. The control device 1 stops the movement of the right measurement moving body 21 in the direction of the arrow, so that the right nail 12 is driven into the game board 11 by the right adjuster 27 as indicated by a virtual line. The controller 1 is tilted outward from the root and the nail interval between the right nail 12 and the left nail 12 is adjusted to the reference nail interval. The entire elevating mechanism 6 is controlled so that the right adjuster 27 returns to the original position and stops.
[0023]
According to the structure of 1st Embodiment, since it expands, measuring the nail space | interval of the nail 12 driven into the game board 11, production efficiency can be improved. Further, since the measurement adjustment mechanism 10 individually moves the left and right adjusters 27 and individually measures the movement distances of the left and right adjusters, the measurement adjustment mechanism 10 widens while measuring the nail interval of the nail 12 driven into the game board 11. , Production efficiency can be improved. In addition, since the measurement adjustment mechanism 10 includes the left and right measurement moving bodies 21 that individually move the left and right adjustment elements 27 and individually measure the movement distances of the left and right adjustment elements 27, the pair of nails 12 that constitute the nail interval. Each nail can be tilted to adjust the nail spacing. Further, if the measurement adjustment mechanism 10 includes the left and right measurement moving bodies 21 and the left and right individual lifting mechanisms 25 that individually lift the left and right adjustment elements 27 with respect to the left and right measurement moving bodies 21, the left and right adjustment elements 27 are provided. The nail spacing can be adjusted with either one of these. Further, when the adjuster 27 can contact both the body 13 and the head 14 of the nail 12, and when the nail contact portion 31 contacts the body 13 of the nail 12, the head 14 of the nail 12 is moved. Since the escape portion 33 is provided, the adjuster 27 can adjust the nail interval using either the body 13 of the nail 12 or the head portion 14 of the nail 12. In addition, since the nail contact portion 31 is formed in an arc shape that makes full contact with a part of the outer peripheral edge of the head 14 of the nail 12, the body 13 of the nail 12 or the head of the nail 12 tilted by the nail contact portion 31. Any of 14 can be held appropriately. In addition, since the nail contact portion 31 is formed to have a thickness that can be inserted between the nail constituted by the nail 12 driven into the game board 11, the nail interval between the nail can be adjusted appropriately. it can.
[0024]
Next, referring to FIG. 8 and FIG. 9, the physical properties of the game board 11, the physical properties of the nail 12, and the responsiveness of the machine are different from each other during the operation of the game board 11, the nail 12 and the machine. In the adjustment work, there is a case where the nail is insufficiently inclined or excessively inclined at the time of adjustment, and readjustment for dealing with it will be described.
[0025]
This readjustment can be executed separately from the adjustment operation in FIG. 5 to FIG. 7 or subsequent to the subsequent stage of the adjustment operation in FIG. 5 to FIG. Here, a case where the readjustment operation is performed subsequent to the subsequent stage of the adjustment operation in FIGS. 5 to 7 will be described as an example. For example, in FIG. 5, after the left and right adjusters 27 move laterally with a force that can bend the nail 12, the control device 1 moves the left and right measurement moving bodies 21 in directions opposite to each other in the directions opposite to the arrows. When the adjuster 27 is separated from the pair of nails 12, the control device 1 stops the lateral movement of the left and right measurement moving bodies 21 in the opposite directions.
[0026]
In this state, the control device 1 again moves the movable base 24 of the left and right measurement moving bodies 21 in a direction away from each other as indicated by an arrow with a force that does not bend the nail 12, and the nail contact portion of the left and right adjusters 27. As 31 comes into contact with the body 13 of the left and right nails 12 and the movement of the movable base 24 stops, the control device 1 calculates the measurement distance based on the measurement distance signal input from the left and right measuring devices 22. By this recalculation, it is verified whether the adjusted measurement distance from the center L1 is inaccurate due to the elasticity of the left and right nails 12 after adjustment in FIG. As a result of this verification, if the measured distance of the left and right nails 12 after adjustment is equal to the reference distance, there is no need to perform readjustment work. When the left and right adjusters 27 return to their original positions that are closest to each other, the control device 1 stops the movement of the left and right measurement moving bodies 21 in the opposite directions.
[0027]
As a result of the verification, if the measured distance between the left and right nails 12 after adjustment does not match the reference distance, readjustment is performed as follows. Specifically, when the verified measurement distance is smaller than the reference distance, the right and left nails 12 after adjustment have slightly returned from the virtual line position shown in FIG. 5 to the solid line position. As the movable base 24 of the left and right measurement moving bodies 21 is laterally moved away from each other as indicated by arrows again with a force that can bend the nail 12 by the output from the control device 1, the control device 1 moves to the right and left measurement devices 22. The measurement distance from the center L1 based on the measurement distance signal input from is calculated, and the calculated measurement distance is compared with the reference distance from the center L1 separately on the left and right. Each time the calculated left and right measurement distances match the reference distance, the control device 1 individually stops the movement of the left and right measurement moving bodies 21 in the arrow directions.
[0028]
As a result of the verification, when the verified measurement distance is larger than the reference distance, the adjusted right and left nails 12 are inclined further outward than the virtual line position. Thus, when the nail interval after adjustment is too wide, for example, there are two correction methods as shown in FIGS.
[0029]
In FIG. 8, the nail 12 indicated by a dotted line is the same unadjusted form as the nail 12 indicated by the solid line in FIGS. 5 and 6, and the left nail 12 indicated by the phantom line is an imaginary line in FIGS. The left nail 12 indicated by a solid line is tilted too far outside the reference distance due to the physical properties of the game board 11, the physical properties of the nail 12, or the responsiveness of the machine. It is a form. The readjustment shown in FIG. 8 is a method of readjusting the left nail 12 with the right adjuster 27 and readjusting the right nail 12 with the left adjuster 27. In this readjustment method, since the left nail 12 is excessively widened, a case where the left nail 12 is adjusted by the right adjuster 27 will be described as an example. After the above-described verification, the control device 1 moves up the entire lifting mechanism 6, and when the left and right adjusters 27 exceed the left and right nails 12, the control device 1 stops moving up and down. The movable base 24 of the measurement moving body 21 is moved to the left side, and the position where the nail contact portion 31 of the right adjuster 27 exceeds the head 14 of the left nail 12 to the left side from the measurement distance calculated by the control device 1. The control device 1 stops the movement of the left and right measurement moving bodies 21 to the left side at a position beyond that.
[0030]
Thereafter, the control device 1 descends the entire lifting mechanism 6, and the control device 1 is located at a position where the upper edge 31 b of the nail contact portion 31 of the right adjuster 27 faces the position P (1 / 2H) of the left nail 12. Stops the lowering of the entire lifting mechanism 6. Thereafter, as the movable base 24 of the right measurement moving body 21 laterally moves in the direction indicated by the arrow with a force that does not bend the nail 12 by the output from the control device 1, the right measurement device 22 is attached to the attachment body 9. When the nail contact portion 31 of the right adjuster 27 contacts the body 13 of the left nail 12, the movement of the movable base 24 stops. In this case, the upper end edge 31 b of the nail contact portion 31 faces the position P that is ½ of the height H of the nail 12. Thereafter, the control device 1 determines that the right adjuster 27 has come into contact with the left nail 12, and determines the measurement distance from the center L1 corresponding to the measurement distance signal input from the right measurement device 22 to the control device 1. The difference between the calculated measurement distance and the reference distance from the right center L1 is calculated. Thereafter, as the movable base 24 of the right measurement moving body 21 laterally moves in the direction indicated by the arrow again with a force capable of bending the left nail 12 with the output based on the calculation of the difference from the control device 1, the control device 1 calculates the measurement distance from the center L1 corresponding to the measurement distance signal input to the control device 1 from the right measuring device 22, and compares the calculated measurement distance with the reference distance from the center L1. When the calculated measurement distance matches the reference distance, the control device 1 stops the movement of the right measurement moving body 21 in the arrow direction. As a result, the right nail 12 is tilted inward from the solid line position to the virtual line position. That is, the posture is changed so that the right nail 12 that has spread too much becomes the reference position. When the right nail 12 that has spread too much is accurately readjusted, the movement of the right movable base 24 in the direction of the arrow stops. Then, when the control device 1 moves the right measurement moving body 21 in the direction opposite to the arrow and returns to the original position where the left and right adjusters 27 are closest, the control device 1 detects the right measurement moving body 21. After stopping the movement in the reverse direction, the control device 1 raises the entire lifting mechanism 6 and prepares a measurement adjustment operation to the next adjustment work position.
[0031]
In FIG. 9, the nail 12 indicated by a dotted line is the same unadjusted form as the nail 12 indicated by a solid line in FIGS. 5 and 6, and the left nail 12 indicated by an imaginary line is an imaginary line in FIGS. The left nail 12 indicated by a solid line is tilted too far outside the reference distance due to the physical properties of the game board 11, the physical properties of the nail 12, or the responsiveness of the machine. It is a form. The readjustment shown in FIG. 9 is a method in which the right nail 12 is readjusted with the right adjuster 27 and the left nail 12 is readjusted with the left adjuster 27. In this readjustment method, since the left nail 12 is excessively widened, a case where the left nail 12 is adjusted by the left adjuster 27 will be described as an example. After the above-described verification, the control device 1 moves up the entire lifting mechanism 6, and when the left and right adjusters 27 exceed the left and right nails 12, the control device 1 stops moving up and down. The movable base 24 of the measurement moving body 21 is moved away from each other, and the nail contact portions 31 of the left and right adjusters 27 move the heads 14 of the left and right nails 12 to the left or right from the measurement distance calculated by the control device 1. The control device 1 stops the movement of the left and right measurement moving bodies 21 at a position exceeding the position.
[0032]
Thereafter, the control device 1 descends the entire lifting mechanism 6, and the control device 1 lowers the entire lifting mechanism 6 at a position where the nail contact portion 31 of the left adjuster 27 faces the body 13 of the left nail 12. Stop. Thereafter, as the movable base 24 of the left measurement moving body 21 moves laterally in the direction indicated by the arrow with a force that does not bend the nail 12 by the output from the control device 1, the left measurement device 22 is attached to the attachment body 9. When the measurement distance signal from the center L1 is output to the control device 1 and the upper back surface of the left adjuster 27 comes into contact with the head 14 of the left nail 12 rather than the nail contact portion 31, the movement of the movable base 24 is performed. Stop. Thereafter, the control device 1 determines that the left adjuster 27 is in contact with the left nail 12 and determines a measurement distance (from the center L1) corresponding to the measurement distance signal input to the control device 1 from the left measurement device 22. Distance) is corrected based on the relationship between the position P of half the height H of the nail 12 and the head 14 of the nail 12, and the difference between the corrected measured distance and the reference distance from the right center L1 is calculated. Calculate. Thereafter, as the movable base 24 of the left measurement moving body 21 laterally moves in the direction indicated by the arrow again with a force capable of bending the left nail 12 with the output based on the calculation of the difference from the control device 1, the control device 1 calculates and corrects the measured distance from the center L1 corresponding to the measured distance signal input to the control device 1 from the left measuring device 22, and compares the corrected measured distance with the reference distance from the center L1. When the corrected measurement distance and the reference distance coincide with each other, the control device 1 stops the movement of the left measurement moving body 21 in the arrow direction. As a result, the right nail 12 is tilted inward from the solid line position to the virtual line position. That is, the posture is changed so that the right nail 12 that has spread too much becomes the reference position. When the right nail 12 that has spread too much is accurately readjusted, the movement of the right movable base 24 in the direction of the arrow stops. Then, when the control device 1 moves the right measurement moving body 21 in the direction opposite to the arrow and returns to the original position where the left and right adjusters 27 are closest, the control device 1 detects the right measurement moving body 21. After stopping the movement in the reverse direction, the control device 1 raises the entire lifting mechanism 6 and prepares a measurement adjustment operation to the next adjustment work position.
[0033]
The idea of readjustment is to change the shape of the adjuster 27 so that a pair of nails 12 are driven into a predetermined position which is an adjustment target of the game board 11 at a distance wider than the diameter of one ball. It can also be applied when adjusting.
[0034]
The measuring device 22 can be similarly applied to a structure in which the linear movement distance of the movable table is used as the loadel distortion and the measurement distance is output as an electric signal.
