Description

【０００１】
【発明の属する技術分野】
この発明は、パチンコ機等の遊技機製造に際し、規格に適合する遊技盤に釘を打ち込むために、遊技盤の反りを検査する装置に関する。
【０００２】
【従来の技術】
パチンコ機メーカーでは、ベニヤ板のような遊技基板の片側表面に意匠盤面としての化粧シートを結合する化粧シート貼工程、事後工程での作業の位置決めとなる基準用孔やガイドレールの取付用孔を切削加工する多軸穴あけ工程、釘や遊技機能部品取付用の下穴を押しあけるゲージプレス工程、遊技機能部品取付用の開口を切削加工するルーター工程、遊技釘や障害釘と呼ばれている釘を打ち込む釘打工程、ガイドレールや遊技機能部品を取り付ける組立工程、遊技機能部品が正常に動作するかを検査する検査工程等を順に経て遊技盤（ゲージ盤）を製造している。
【０００３】
【発明が解決しようとする課題】
ところで、反り、外形、厚さ等が規格に収まっている良品の遊技基板のみを初期工程に供給して、不良品の発生を抑えることが考えられる。しかし、ルーター工程で比較的大きな開口が化粧シートと遊技基板とからなる遊技盤に多数形成されることから、遊技盤での内部応力が変化し、遊技盤に規格外の反りを生じることがあり、この反りの発生した遊技盤に釘を打ち込んでも不良品となってしまう不都合がある。
【０００４】
そこで、この発明は、釘打工程に先駆けて遊技盤の反りを検査し、規格外の反りが発生した遊技盤への釘打ちを廃止すると共に、良品の遊技盤のみに釘打ちを実行することにより、不良品の発生を防止して、生産効率を向上することができる遊技機製造用遊技盤の反り検査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に係る遊技機製造用遊技盤の反り検査装置は、釘打工程に先駆けて遊技盤の意匠盤面を上に向けた状態で遊技盤を一方向に搬送するコンベアと、コンベアよりも下部にコンベアから離れて設けられた下側固定板と、コンベアよりも上部にコンベアから離れて設けられた上側固定板と、上側固定板に反り検査を行うために設けられた複数のセンサーと、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に位置するように停止させるために下側固定板に昇降可能に設けられた搬送ストッパーと、下側固定板に昇降可能に設けられた下側支持ピンと、電気的な処理部とを備え、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に搬送ストッパーで停止し、この停止された遊技盤を上昇する下側支持ピンでコンベアより上方に持ち上げ、この持ち上げられた遊技盤の反りを各センサーが電気的に検出して処理部に出力し、下側支持ピンが下降することによって遊技盤を下側支持ピンからコンベアに受け渡す一方、処理部は、各センサーからの出力による遊技盤の反りが予め定めた許容範囲外であればその遊技盤をコンベアの外に除去するための不良信号を発生し、各センサーからの出力による遊技盤の反りが予め定めた許容範囲内であれば前記不良信号を発生しないことを特徴としている。この請求項１に係る遊技機製造用遊技盤の反り検査装置によれば、コンベアで搬送される遊技盤が下側固定板の真上に到着すると、搬送ストッパーが遊技盤を停止し、下側支持ピンが遊技盤をコンベアより上方に持ち上げた状態において、各センサーが電気的に検出して処理部に出力することによって、処理部が各センサーからの出力による遊技盤の反りが予め定めた許容範囲外であればその遊技盤をコンベアの外に除去するための不良信号を発生するので、この処理部からの不良信号に基づき、遊技盤の反りが予め定めた許容範囲外の不良品としての遊技盤をコンベアの外に除去して釘打工程に供給せず、各センサーからの出力による遊技盤の反りが予め定めた許容範囲内であれば前記不良信号を発生しないので、反り検査の終了した良品としての遊技盤を釘打工程に供給することができる。請求項２に係る遊技機製造用遊技盤の反り検査装置は、釘打工程に先駆けて遊技盤の意匠盤面を上に向けた状態で遊技盤を一方向に搬送するコンベアと、コンベアよりも下部にコンベアから離れて設けられた下側固定板と、コンベアよりも上部にコンベアから離れて設けられた上側固定板と、上側固定板に反り検査を行うために設けられたオン・オフ動作する複数のセンサーと、この上側固定板における各センサーと上下で相対峙するように下側固定板位置に反り検査を行うために設けられたオン・オフ動作する複数のセンサーと、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に位置するように停止させるために下側固定板に昇降可能に設けられた搬送ストッパーと、下側固定板に昇降可能に設けられた下側支持ピンと、電気的な処理部とを備え、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に搬送ストッパーで停止し、この停止された遊技盤を上昇する下側支持ピンでコンベアより上方に持ち上げ、この持ち上げられた遊技盤に対し上側固定板における各センサーと下側固定板における各センサーとがオンまたはオフの信号を処理部に出力し、下側支持ピンが下降することによって遊技盤を下側支持ピンからコンベアに受け渡す一方、処理部は、上側固定板におけるセンサーと下側固定板におけるセンサーとからの出力がオン・オフの相反する動作状態であればその遊技盤を反りの大きい不良品と判定してコンベアの外に除去するための不良信号を発生し、前記上側固定板におけるセンサーと下側固定板におけるセンサーとからの出力がオンまたはオフのいずれか一方の同じ動作状態であればその遊技盤を反りの小さい良品と判定して前記不良信号を発生しないことを特徴としている。この請求項２に係る遊技機製造用遊技盤の反り検査装置によれば、コンベアで搬送される遊技盤が下側固定板の真上に到着すると、搬送ストッパーが遊技盤を停止し、下側支持ピンが遊技盤をコンベアより上方に持ち上げた状態において、上側固定板における各センサーと下側固定板における各センサーとがオンまたはオフの信号を処理部に出力することによって、上側固定板におけるセンサーと下側固定板におけるセンサーとからの出力がオン・オフの相反する動作状態であれば、処理部が遊技盤をコンベアの外に除去するための不良信号を発生するので、この処理部からの不良信号に基づき、遊技盤の反りが予め定めた許容範囲外の不良品としての遊技盤をコンベアの外に除去して釘打工程に供給せず、上側固定板におけるセンサーと下側固定板におけるセンサーとからの出力がオンまたはオフのいずれか一方の同じ動作状態であれば、処理部が不良信号を発生しないので、反り検査の終了した良品としての遊技盤を釘打工程に供給することができる。請求項３に係る遊技機製造用遊技盤の反り検査装置は、釘打工程に先駆けて遊技盤の意匠盤面を上に向けた状態で遊技盤を一方向に搬送するコンベアと、コンベアよりも下部にコンベアから離れて設けられた下側固定板と、コンベアよりも上部にコンベアから離れて設けられた上側固定板と、上側固定板の中心点に設けられた軸より側方に突出するアームの先端に反り検査を行うために設けられたセンサーと、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に位置するように停止させるために下側固定板に昇降可能に設けられた搬送ストッパーと、下側固定板に昇降可能に設けられた下側支持ピンと、電気的な処理部とを備え、遊技盤をコンベアで搬送して上側固定板と下側固定板との間に搬送ストッパーで停止し、この停止された遊技盤を上昇する下側支持ピンでコンベアより上方に持ち上げ、この持ち上げられた遊技盤の反りを軸の回転で遊技盤に対して回転するセンサーが電気的に検出して処理部に出力し、下側支持ピンが下降することによって遊技盤を下側支持ピンからコンベアに受け渡す一方、処理部は、センサーからの出力による遊技盤の反りが予め定めた許容範囲外であればその遊技盤をコンベアの外に除去するための不良信号を発生し、センサーからの出力による遊技盤の反りが予め定めた許容範囲内であれば前記不良信号を発生しないことを特徴としている。この請求項３に係る遊技機製造用遊技盤の反り検査装置によれば、コンベアで搬送される遊技盤が下側固定板の真上に到着すると、搬送ストッパーが遊技盤を停止し、下側支持ピンが遊技盤をコンベアより上方に持ち上げた状態において、軸の回転で遊技盤に対して回転するセンサーが電気的に検出して処理部に出力することによって、処理部が各センサーからの出力による遊技盤の反りが予め定めた許容範囲外であればその遊技盤をコンベアの外に除去するための不良信号を発生するので、この処理部からの不良信号に基づき、遊技盤の反りが予め定めた許容範囲外の不良品としての遊技盤をコンベアの外に除去して釘打工程に供給せず、各センサーからの出力による遊技盤の反りが予め定めた許容範囲内であれば前記不良信号を発生しないので、反り検査の終了した良品としての遊技盤を釘打工程に供給することができる。請求項４に係る遊技機製造用遊技盤の反り検査装置は、釘打工程に先駆けて遊技盤の意匠盤面を上に向けた状態で遊技盤を一方向に搬送するコンベアと、コンベアよりも下部にコンベアから離れて設けられた下側固定板と、コンベアよりも上部にコンベアから離れて設けられた上側固定板と、上側固定板の中心点に設けられた軸より側方に突出するアームの先端に反り検査を行うために設けられたオン・オフ動作するセンサーと、コンベアで搬送される遊技盤を上側固定板と下側固定板との間に位置するように停止させるために下側固定板に昇降可能に設けられた搬送ストッパーと、下側固定板に昇降可能に設けられた下側支持ピンと、電気的な処理部とを備え、遊技盤をコンベアで搬送して上側固定板と下側固定板との間に搬送ストッパーで停止し、この停止された遊技盤を上昇する下側支持ピンでコンベアより上方に持ち上げ、この持ち上げられた遊技盤の反りを軸の回転で遊技盤に対して回転するセンサーがオンまたはオフの信号を処理部に出力し、下側支持ピンが下降することによって遊技盤を下側支持ピンからコンベアに受け渡す一方、処理部は、回転するセンサーからオン信号が出力されればその遊技盤を反りの大きい不良品と判定してコンベアの外に除去するための不良信号を発生し、回転するセンサーからオン信号が出力されなければその遊技盤を反りの小さい良品と判定して前記不良信号を発生しないことを特徴としている。この請求項４に係る遊技機製造用遊技盤の反り検査装置によれば、コンベアで搬送される遊技盤が下側固定板の真上に到着すると、搬送ストッパーが遊技盤を停止し、下側支持ピンが遊技盤をコンベアより上方に持ち上げた状態において、軸の回転で遊技盤に対して回転するセンサーがオン信号を処理部に出力することによって、処理部が遊技盤をコンベアの外に除去するための不良信号を発生するので、この処理部からの不良信号に基づき、遊技盤の反りが予め定めた許容範囲外の不良品としての遊技盤をコンベアの外に除去して釘打工程に供給せず、軸の回転で遊技盤に対して回転するセンサーがオフ信号を処理部に出力することによって、処理部が不良信号を発生しないので、反り検査の終了した良品としての遊技盤を釘打工程に供給することができる。請求項１乃至４のいずれかに記載の遊技機製造用遊技盤の反り検査装置における上側固定板に上側支持ピンを設け、上昇する下側支持ピンでコンベアより上方に持ち上げられた遊技盤を上側支持ピンと下側支持ピンとで挟むように支持すれば、センサーが上側支持ピンと下側支持ピンとで支持されている遊技盤の反りを検出することができる。請求項１乃至５のいずれかに記載の遊技機製造用遊技盤の反り検査装置における下側支持ピンが３点で遊技盤を持ち上げる配置であるか、または、下側支持ピンおよび上側支持ピンが３点で遊技盤を挟むように支持する配置であれば、センサーが下側支持ピンによる３点支持でコンベアより上方に持ち上げられている遊技盤または上側支持ピンと下側支持ピンとの３点支持でコンベアより上方で支持されている遊技盤の反りを検出することができる。請求項１乃至４のいずれかに記載の遊技機製造用遊技盤の反り検査装置における各センサーが上側固定板の対角線と中心点を中心とする円との４つの交点に対応するように上側固定板に設けられ、各下側支持ピンが下側固定板の対角線と中心点を中心とすると共に上側固定板の円と同心で当該円よりも小さい半径の円と下側固定板の対角線との２つの交点と、これら２つの交点の中心点を境とする反対側で下側固定板の対角線による挟角の２等分線と上記小さい半径の円との１つの交点とからなる３つの交点に対応するように下側固定板に設けられれば、センサーの個数を少なくして検出精度を向上することができる。請求項１乃至４のいずれかに記載の遊技機製造用遊技盤の反り検査装置における上側固定板が、コンベアの搬送方向の一側に位置する位置決め突起と、コンベアの搬送方向の前側に位置する位置決め突起と、下側支持ピンでコンベアより上方に持ち上げられた遊技盤をコンベアの搬送方向の一側に位置する位置決め突起に対して押す位置決め突起と、下側支持ピンでコンベアより上方に持ち上げられた遊技盤をコンベアの搬送方向の前側に位置する位置決め突起に対して押す縦プッシャーとを備えれば、下側支持ピンでコンベアより上方に持ち上げられた遊技盤の側面を位置決め突起および縦プッシャーとで位置決め突起に押し付けてセンサーに対する反りを検査する遊技盤を位置決めすることができる。要するに、本発明に係る遊技機製造用遊技盤の反り検査装置は、釘打工程に先駆けて遊技盤の反りを検査し、規格外の反りが発生した遊技盤への釘打ちを廃止し、良品の遊技盤のみに釘打ちを実行することにより、釘打工程及びそれ以降の工程での反りによる不良品の発生を防止して、生産効率を向上できる。
【０００６】
【発明の実施の形態】
図１〜図４は一実施形態を示している。図１において、先ず、ルーター工程１では、化粧シート貼工程、多軸穴あけ工程、ゲージプレス工程の各工程を経て遊技基板に意匠盤面としての化粧シートが結合された遊技盤５に、遊技機能部品取付用の開口を切削加工する。次に、反り検査工程２において、遊技盤５の反りを電気的に検出し、その検出した反りが予め設定された許容範囲内であれば、反りが小さくその遊技盤５が良品であると判定し、逆に、反りが予め設定された許容範囲外であれば、反りが大きくその遊技盤５は不良品であると判定する。そして、排出工程３において、上記検査工程で不良品と判定された遊技盤５を反り検査工程２又は反り検査工程２と釘打工程４との間より取り出す。釘打工程４においては、反り検査工程２で良品と判定された遊技盤５に遊技釘や障害釘と呼ばれている多数の釘をその遊技盤５の機種に応じて打ち込む。即ち、釘打工程４に先駆けて遊技盤５の反りを検査し、規格外の反りが発生した遊技盤５への釘打ちを廃止し、良品の遊技盤５のみに釘打ちを実行することにより、釘打工程４及びそれ以降の工程での不良品の発生を防止して、生産効率を向上できる。
【０００７】
図２において、前記反り検査工程２、排出工程３、釘打工程４の各工程に用いる装置について説明する。ルーター工程１を経た遊技盤５は、ベニヤ板のような遊技基板５ａの片側表面に意匠盤面を構成する化粧シート５ｂを接着した形態で、センター役物、入賞口、サイドランプ、ストップランプ、賞球数ランプ、変動入賞口、アウト口等の各種遊技機能部品を取り付けるための開口５ｃ、及び各工程での作業の位置決めとなる基準用孔５ｄを備え、コンベア６で搬送方向Ｘに搬送される。このコンベア６は、搬送方向Ｘと直交する方向に所定間隔を以て相対峙された一対のコンベアフレーム６ａに複数のローラー６ｂを搬送方向Ｘに並列配置して回転可能に取り付け、各ローラー６ｂを全部又は搬送方向Ｘに飛び飛びに電気的に駆動して遊技盤５を搬送し、各コンベアフレーム６ａの上に遊技盤５を搬送方向Ｘに誘導するガイドレール６ｃを備えている。
【０００８】
反り検査工程２での反り検査装置１１は、コンベアフレーム６ａの下部に敷設結合された下側固定板１１ａと、この下側固定板１１ａに支柱１１ｂでローラー６ｂの上側搬送部より上方に離隔して当該上側搬送部と略平行となるように固定支持された上側固定板１１ｃと、この上側固定板１１ｃにエアーシンリンダーのピストンロッドの移動量を磁電変換して出力するマグネットスケールのような反り検査を行う複数のセンサー１１ｄと、を有する。
【０００９】
図３のａ，ｂ図にも示すように、この実施形態の場合、各センサー１１ｄは、上側固定板１１ｃの対角線Ｌ１，Ｌ２と中心点イを中心とする円Ｌ３との４つの交点ロ，ハ，ニ，ホのように、遊技盤５の孔や開口等の形成されていない遊技盤５の異なる機種で共通する未加工部分に対応するように、上側固定板１１ｃに設けられ、各測定子１１ｅとしてのピストンロッドを４つの交点ロ〜ホで上側固定板１１ｃの下面に貫通している。上側固定板１１ｃは測定基準となる３つの上側支持ピン１１ｆ、複数の位置決め突起１１ｇ、横プッシャー１１ｈ及び縦プッシャー１１ｊを備えている。各上側支持ピン１１ｆは、円Ｌ３と同心で円Ｌ３よりも小さい半径の円Ｌ４と対角線Ｌ１，Ｌ２との２つの交点ヘ，ト、これらの交点ヘ，トの中心点イを境とする反対側で対角線Ｌ１，Ｌ２による挟角の２等分線Ｌ５と円Ｌ４との交点チのそれぞれに設けられ、各測定基準面としての下面をローラー６ｂの上側搬送部と平行に形成している。位置決め突起１１ｇは、搬送方向Ｘの前側に位置して、上側固定板１１ｃの前縁部で上側固定板１１ｃの中心点イより左右に等距離に離隔した位置と、搬送方向Ｘの一側に位置する上側固定板１１ｃの一側縁部で前縁部に近接した位置との合計３ケ所において、上側固定板１１ｃの下面に突出している。横プッシャー１１ｈは、エアーシンリンダーにより形成され、ピストンロッドの先端に取り付けられた押圧子１１ｉを搬送方向Ｘの一側の位置決め突起１１ｇと対向するように、上側固定板１１ｃの下面に設けられている。縦プッシャー１１ｊは、エアーシンリンダーにより形成され、ピストンロッドの先端に取り付けられた押圧子１１ｋを搬送方向Ｘの前側の左右の位置決め突起１１ｇ間の中心に位置するように、上側固定板１１ｃの下面に設けられている。下側固定板１１ａには搬送ストッパー１１ｍを上側固定板１１ｃの前縁部側の位置決め突起１１ｇよりも搬送方向Ｘの上流側に位置するように配置してある。搬送ストッパー１１ｍは下側固定板１１ａに取り付けられた図外のエアーシリンダーで１組のローラー６ｂ間の隙間を経て上側搬送部よりも上位と下位とに昇降動作する。
【００１０】
又、図３のｂ図において、下側固定板１１ａとコンベア６との間に配置されたリフトベース１１ｎは、下側固定板１１ａの下面に設置されたダブルシリンダー１１ｐにより２段階的な上昇と停止とを行う一方、ダブルシリンダー１１ｐの昇降動作の際に、水平方向にふらつかないよう下側固定板１１ａに設けられた図外のガイド機構に摺接係合している。リフトベース１１ｎには下側支持ピン１１ｑを上側固定板１１ｃの上側支持ピン１１ｆと上下で同軸状となるように立設してある。各下側支持ピン１１ｑの上面は上側支持ピン１１ｆの下面と平行な支持面を形成している。各下側支持ピン１１ｑは、リフトベース１１ｎが下降限度位置に停止中においては、ローラー６ｂ上を搬送される遊技盤５に干渉しないようにローラー６ｂの上側搬送部よりも下方に位置し、リフトベース１１ｎの上昇動作でローラー６ｂ間の隙間を通って遊技盤５をローラー６ｂより持ち上げて上側支持ピン１１ｆとで挟むように支持する。
【００１１】
この反り検査装置１１においては、１つの遊技盤５がコンベア６で搬送されて上側固定板１１ｃと下側固定板１１ａとの間に到着し、遊技盤５の前縁がローラー６ｂ間より上方に突出した搬送ストッパー１１ｍに当接した後に、コンベア６の搬送動作が中断する。このコンベア６の搬送動作が中断してから、後述するコンベア６の搬送動作の再開で遊技盤５が次の工程側に搬送され始めるまでの間に、搬送ストッパー１１ｍは遊技盤５の搬送を邪魔しないようローラー６ｂの上側搬送部より下位に下降する。そして、ダブルシリンダー１１ｐが第１段目に伸長駆動し、下側支持ピン１１ｑがリフトベース１１ｎと一緒に下降限度位置から上昇して遊技盤５をコンベア６のガイドレール６ｃより上方に持ち上げた後に、前記ダブルシリンダー１１ｐの第１段目の伸長駆動が停止して、リフトベース１１ｎを第１上昇停止位置に停止する。この第１停止位置では、図３のｃ図に示すように、遊技盤５の側面が位置決め突起１１ｇと横プッシャー１１ｈと縦プッシャー１１ｊとの間に位置すると共に、遊技盤５の上面が上側支持ピン１１ｆに未接触な状態である。その後、横プッシャー１１ｈの押圧子１１ｉ及び縦プッシャー１１ｊの押圧子１１ｋが遊技盤５を位置決め突起１１ｇ側に押すことにより、遊技盤５が位置決め突起１１ｇを基準として位置決めされ、この位置決めの結果、遊技盤５の中心が上側固定板１１ｃの中心点イとほぼ同軸状に配置される。
【００１２】
引き続き、ダブルシリンダー１１ｐが第２段目に伸長駆動して下側支持ピン１１ｑを第１上昇停止位置から再び上昇して遊技盤５をさらに持ち上げた後に、前記ダブルシリンダー１１ｐの第２段目の伸長駆動が停止して、リフトベース１１ｎを第２上昇停止位置に停止する。この第２停止位置では、図３のｄ図に示すように、遊技盤５が上側支持ピン１１ｆと下側支持ピン１１ｑとで挟むように３点で支持される。そして、各センサー１１ｄの測定子１１ｅが下降動作して遊技盤５の上面に接触し、各センサーが下降量に相当する電気信号を図２に示すコンピューターを内蔵する電気的な処理部１１ｒに出力した後に、測定子１１ｅが上昇動作して元の位置に復帰すると共に、横プッシャー１１ｈの押圧子１１ｉ及び縦プッシャー１１ｊの押圧子１１ｋが元の位置に復帰した後に、ダブルシリンダー１１ｐが第１上昇停止位置での一時停止を行うことなく縮小駆動し、下側支持ピン１１ｑがリフトベース１１ｎと一緒に第２上昇停止位置から下降限度位置に停止する。この下降途中において、遊技盤５がコンベア６のガイドレール６ｃの間よりローラー６ｂ上に搭載される。そして、コンベア６が搬送動作を再開して遊技盤５を次の工程に向けて図２に示す搬送方向Ｘに搬送する。
【００１３】
一方、処理部１１ｒは各センサー１１ｄからの出力を各測定点ロ〜ホでの基準面との差に変換し、即ち、測定子１１ｅの先端が上側支持ピン１１ｆの基準面である下面と同一平面内に位置する移動量をゼロ点（基準）とし、各測定点ロ〜ホにおけるゼロ点から遊技盤５の反りによる変位量を演算し、各演算結果である前記差が予め設定された許容範囲外であれば、反りが大きくて使用に差し支えることを意味するので、当該遊技盤５を不良品と判定して、その遊技盤５をコンベア６の外に除去するための不良信号を発生し、逆に、前記各演算結果である差が予め設定された許容範囲内であれば、反りが小さくて使用をしても差し支えないことを意味するので、当該遊技盤５を良品と判定して、前記不良信号は発生しない。
【００１４】
要するに、この反り検査装置１１によれば、コンベア６で搬送された遊技盤５が下側固定板１１ａの真上に到着した際に、上昇限度位置の搬送ストッパー１１ｍで遊技盤５を当接停止した後に、コンベア６の搬送動作を停止し、リフトベース１１ｎを上昇動作して下側支持ピン１１ｑで遊技盤５をコンベア６より浮上支持して上側支持ピン１１ｆとで挟むように３点支持して、処理部１１ｒで４点配置のセンサー１１ｄからの出力を各測定点ロ〜ホでの基準面との差に変換して遊技盤５の反りとして検出した後に、リフトベース１１ｎを下側支持ピン１１ｑがコンベア６の上側搬送部より下位となるように下降動作して、その下降途中で遊技盤５をコンベア６に受け渡すことで、遊技盤５の反りを自動的に全数検査できる。又、センサー１１ｄを浮上支持された遊技盤５の異なる機種に共通する未加工部分に対応して位置する交点ロ〜ホの４点に配置したことにより、センサー１１ｄの個数を最も少なくして検出精度を向上することができる。その理由は、遊技盤５の遊技基板５ａがベニヤ板の場合、ベニヤ板はそれを構成する上層の木の繊維と下層の木の繊維とが直交された状態で多段に重ね合わせてあり、遊技盤５の４辺の中央よりも各コーナー部に顕著に出易いからである。
【００１５】
再び、図２に戻り、排出工程３での排出装置１２は、コンベア６の下流側に連続するように配置された一対の搬送機構１２ａを備えている。搬送機構１２ａは、固定ベース１２ｂを搬送方向Ｘと直交する方向に所定間隔を以て相対峙して配置し、各固定ベース１２ｂに取り付けられたエアーシリンダーのようなアクチュエーター１２ｃにより搬送方向Ｘと直交する方向に前進後退する可動板１２ｄの内側面に複数のローラー１２ｅを搬送方向Ｘに一列状に配置して回転可能に取り付け、各ローラー１２ｅに図外のモーターの動力をゴムベルト１２ｅ−１（図４のａ図参照）のような無端状部材で伝達し、各ローラー１２ｅを電気的に駆動することで、反り検査装置１１を経てコンベア６より搬出された遊技盤５を搬送方向Ｘに搬送する。各ローラー１２ｅより上方に突出する可動板１２ｄの内側面はローラー１２ｅで搬送される遊技盤５を搬送方向Ｘに誘導するガイド部になっている。又、固定ベース１２ｂは基板ストッパー１２ｆと受渡機構１２ｈとを備えている。
【００１６】
基板ストッパー１２ｆは、前述の反り検査装置１１が遊技盤５の不良未検出中は、固定ベース１２ｂに取り付けられたエアーシリンダーのようなアクチュエーター１２ｇにより搬送機構１２ａによる遊技盤５の搬送路上より退避するように後退限度位置に停止していて、遊技盤５の搬送を継続させ、反り検査装置１１が遊技盤５の不良を検出し、不良として検出された遊技盤５が搬送機構１２ａに移送された際に、アクチュエーター１２ｇにより後退限度位置より前進して遊技盤５の搬送路上に突出するように前進限度位置に停止することで、遊技盤５の搬送を強制的に停止する。
【００１７】
受渡機構１２ｈは、可動板１２ｄの後退で搬送機構１２ａの間より落下する遊技盤５の落下姿勢を搬送機構１２ａでの搬送姿勢と同様な水平面状に矯正するものであって、固定ベース１２ｂに取り付けられたエアーシリンダーのようなアクチュエーター１２ｉにより搬送機構１２ａの可動板１２ｄと同方向に前進後退可能に設けられた受体１２ｊと、受体１２ｊの近傍でアクチェーター１２ｉのケーシングのような静止部に取り付けられた突当棒１２ｋとを備え、反り検査装置１１が遊技盤５の不良未検出中は、受体１２ｊが搬送機構１２ａの１組のローラー１２ｅ間で可動体に形成された切欠部１２ｍより後退限度位置に停止しており、反り検査装置１１が遊技盤５の不良を検出し、不良として検出された遊技盤５が搬送機構１２ａに移送された際に、受体１２ｊが搬送機構１２ａの切欠部１２ｍを経由して前進限度位置に停止することで、受体１２ｊの水平片が搬送機構１２ａのローラー１２ｅ上に位置する遊技盤５の下に潜り込み、受体１２ｊの垂直片が遊技盤５の前後側面に近接対向する。そして、搬送機構１２ａの可動板１２ｄが後退し、ローラー１２ｅの間より落下する遊技盤５が受体１２ｊの水平片の上に搭載された後に、受体１２ｊが後退限度位置に停止することで、前後方向に相対峙する受体１２ｊの水平片の間隔が遊技盤５の横幅より大きい寸法に設定されて、当該前後方向に相対峙する受体１２ｊの間より遊技盤５が落下する。突当棒１２ｋの先端は、搬送機構１２ａの前進限度位置に停止した可動板１２ｄの切欠部１２ｍにおいて、遊技盤５の前後側面に近接対向するように、可動板１２ｄの内側面と略面一に位置していて、搬送機構１２ａで搬送される遊技盤５と干渉しないようになっている。又、突当棒１２ｋの先端は、搬送機構１２ａの後退限度位置への停止で可動板１２ｄの切欠部１２ｍより内側に突出して、受体１２ｊが後退限度位置に停止する際に、遊技盤５が受体１２ｊに共連れされるのを防止して、遊技盤５を受体１２ｊより傾くことなく水平面状に落下させる。

In this warpage inspection device 11, one game board 5 is conveyed by the conveyor 6 and arrives between the upper fixed plate 11c and the lower fixed plate 11a, and the front edge of the game board 5 is located above the interval between the rollers 6b. After contacting the protruding transport stopper 11m, the transport operation of the conveyor 6 is interrupted. The transport stopper 11m obstructs the transport of the game board 5 after the transport operation of the conveyor 6 is interrupted until the game board 5 starts to be transported to the next process side by resuming the transport operation of the conveyor 6 described later. The lower part of the roller 6b is lowered below the upper conveying part. After the double cylinder 11p is driven to extend to the first stage, the lower support pin 11q rises from the lower limit position together with the lift base 11n, and lifts the game board 5 above the guide rail 6c of the conveyor 6. The extension drive of the first stage of the double cylinder 11p is stopped, and the lift base 11n is stopped at the first ascending stop position. At the first stop position, as shown in FIG. 3c, the side surface of the game board 5 is located between the positioning projection 11g, the horizontal pusher 11h, and the vertical pusher 11j, and the upper surface of the game board 5 is supported on the upper side. The pin 11f is not in contact. Thereafter, the pusher 11i of the horizontal pusher 11h and the pusher 11k of the vertical pusher 11j push the game board 5 toward the positioning protrusion 11g, so that the game board 5 is positioned with reference to the positioning protrusion 11g. As a result of this positioning, the game The center of the board 5 is arranged substantially coaxially with the center point A of the upper fixing plate 11c.
[0012]
Subsequently, after the double cylinder 11p is driven to extend to the second stage and the lower support pin 11q is raised again from the first ascending stop position to further lift the game board 5, the second stage of the double cylinder 11p is moved to the second stage. The extension drive is stopped, and the lift base 11n is stopped at the second ascending stop position. At this second stop position, as shown in FIG. 3d, the game board 5 is supported at three points so as to be sandwiched between the upper support pin 11f and the lower support pin 11q. Then, the measuring element 11e of each sensor 11d descends to come into contact with the upper surface of the game board 5, and each sensor outputs an electrical signal corresponding to the descending amount to the electrical processing unit 11r incorporating the computer shown in FIG. After that, the measuring element 11e moves up and returns to the original position, and after the pressing element 11i of the horizontal pusher 11h and the pressing element 11k of the vertical pusher 11j return to the original position, the double cylinder 11p rises first. The lower support pin 11q is stopped from the second ascending stop position to the descending limit position together with the lift base 11n without being temporarily stopped at the stopping position. In the middle of the descent, the game board 5 is mounted on the roller 6b from between the guide rails 6c of the conveyor 6. Then, the conveyor 6 resumes the transport operation and transports the game board 5 in the transport direction X shown in FIG. 2 for the next process.
[0013]
On the other hand, the processing unit 11r converts the output from each sensor 11d into a difference from the reference surface at each measurement point B to E, that is, the tip of the measuring element 11e is the same as the lower surface that is the reference surface of the upper support pin 11f. The amount of movement located in the plane is set as a zero point (reference), the amount of displacement due to warping of the game board 5 is calculated from the zero point at each of the measurement points B to E, and the difference that is the result of each calculation is set in advance. If it is out of the range, it means that the warp is too large to be used, so that the game board 5 is determined as a defective product and a failure signal for removing the game board 5 from the conveyor 6 is generated. On the contrary, if the difference that is the result of each calculation is within a preset allowable range, it means that the warp is small and may be used, so the game board 5 is determined as a non-defective product. Thus, the failure signal is not generated.
[0014]
In short, according to this warpage inspection device 11, when the game board 5 conveyed by the conveyor 6 arrives just above the lower fixed plate 11a, the game board 5 is brought into contact with and stopped by the conveyance stopper 11m at the rising limit position. After that, the conveying operation of the conveyor 6 is stopped, the lift base 11n is raised, the game board 5 is supported by being floated from the conveyor 6 by the lower support pins 11q, and is supported by the upper support pins 11f. After the processing unit 11r detects the warp of the game board 5 by converting the output from the sensor 11d arranged at four points into the difference from the reference plane at each measurement point ro to ho, the lift base 11n is supported on the lower side. The warping of the game board 5 can be automatically inspected by moving the pin 11q downward so that the pins 11q are lower than the upper conveying part of the conveyor 6 and transferring the game board 5 to the conveyor 6 during the lowering. In addition, the sensors 11d are detected at the least number of sensors 11d by arranging the sensors 11d at the four points of intersections (b) to (c) corresponding to the unprocessed portions common to the different models of the game board 5 that are levitated and supported. Accuracy can be improved. The reason is that when the game board 5a of the game board 5 is a plywood board, the plywood board is superposed in multiple stages in a state in which the upper-layer wood fibers and the lower-layer wood fibers constituting it are orthogonal to each other. This is because it is more likely to appear at each corner than the center of the four sides.
[0015]
Returning again to FIG. 2, the discharging device 12 in the discharging step 3 includes a pair of transport mechanisms 12 a arranged to be continuous downstream of the conveyor 6. In the transport mechanism 12a, the fixed base 12b is disposed in a direction perpendicular to the transport direction X with a predetermined interval therebetween, and a direction orthogonal to the transport direction X by an actuator 12c such as an air cylinder attached to each fixed base 12b. A plurality of rollers 12e are arranged in a row in the transport direction X on the inner surface of the movable plate 12d that moves forward and backward in the direction of rotation, and is rotatably attached to each roller 12e. The game board 5 transported from the conveyor 6 through the warp inspection device 11 is transported in the transport direction X by being transmitted by an endless member as shown in FIG. a) and electrically driving each roller 12e. The inner side surface of the movable plate 12d protruding upward from each roller 12e is a guide portion for guiding the game board 5 conveyed by the roller 12e in the conveyance direction X. The fixed base 12b includes a substrate stopper 12f and a delivery mechanism 12h.
[0016]
The substrate stopper 12f is retracted from the transport path of the game board 5 by the transport mechanism 12a by an actuator 12g such as an air cylinder attached to the fixed base 12b while the warp inspection device 11 is not detecting a defect of the game board 5. The warp inspection device 11 detects a failure of the game board 5 and the game board 5 detected as defective is transferred to the transport mechanism 12a. At this time, the actuator 12g moves forward from the retreat limit position and stops at the advance limit position so as to protrude onto the transport path of the game board 5, thereby forcibly stopping the transport of the game board 5.
[0017]
The delivery mechanism 12h corrects the falling posture of the gaming board 5 that falls from between the transport mechanisms 12a by the retreat of the movable plate 12d into a horizontal plane similar to the transport posture in the transport mechanism 12a, and is attached to the fixed base 12b. A receiver 12j provided so as to be able to advance and retreat in the same direction as the movable plate 12d of the transport mechanism 12a by an attached actuator 12i such as an air cylinder, and a stationary part such as a casing of the actuator 12i in the vicinity of the receiver 12j. A notch portion 12m formed on a movable body between the pair of rollers 12e of the transport mechanism 12a while the warp inspection device 11 is not detecting a failure of the game board 5 while the warp inspection device 11 is detected. The warp inspection device 11 detects a failure of the gaming board 5 and the gaming board 5 detected as defective is transferred to the transport mechanism 12a. In this case, the receiving body 12j stops at the forward limit position via the notch 12m of the transport mechanism 12a, so that the horizontal piece of the receiving body 12j is positioned on the roller 12e of the transport mechanism 12a. It sinks below and the vertical piece of the receiver 12j is close to and faces the front and rear side surfaces of the game board 5. Then, after the movable plate 12d of the transport mechanism 12a moves backward and the game board 5 falling from between the rollers 12e is mounted on the horizontal piece of the receiver 12j, the receiver 12j stops at the retreat limit position. The distance between the horizontal pieces of the receiving body 12j facing in the front-rear direction is set to be larger than the lateral width of the gaming board 5, and the gaming board 5 falls from between the receiving bodies 12j facing in the front-rear direction. The tip of the abutting bar 12k is substantially flush with the inner surface of the movable plate 12d so as to face and oppose the front and rear side surfaces of the game board 5 at the notch 12m of the movable plate 12d stopped at the forward limit position of the transport mechanism 12a. The game board 5 is transported by the transport mechanism 12a so as not to interfere with the game board 5. Further, the tip of the abutting bar 12k protrudes inward from the notch 12m of the movable plate 12d when the transport mechanism 12a stops at the retreat limit position, and when the receiving body 12j stops at the retreat limit position, the game board 5 Is prevented from being carried together with the receptacle 12j, and the game board 5 is dropped in a horizontal plane without being inclined with respect to the receptacle 12j.
[0018]
In the discharge device 12, the warp detection device 11 detects a defect when the movable plate 12d of the transport mechanism 12a is stopped at the forward limit position and the transport mechanism 12a can carry the game board 5 over the conveyor 6. When the game board 5 as a defective product from which the signal is output and the defect detection signal is output is transferred from the conveyor 6 to the transfer mechanism 12a as shown in FIG. 4a, the board protruding on the transfer path The stopper 12 f regulates the conveyance of the game board 5. Next, as shown in FIG. 4b, the receiving plate 12j of the delivery mechanism 12h moves forward and sinks below the front-rear direction of the game board 5 above the roller 12e. Thereafter, as shown in FIG. 4c, the movable plate 12d moves backward, the roller 12e escapes from the game board 5, and the game board 5 is supported by the receiver 12j. Subsequently, the receiver 12j moves backward. At the time of the retreat, the abutting bar 12k corresponds to the side surface of the gaming board 5 in the front-rear direction, so that the gaming board 5 abuts against the abutting bar 12k even if the gaming board 5 tries to share with the receptacle 12j. Thus, the game board 5 is prevented from being accompanied, and the game board 5 falls from the receiving plate 12j while maintaining a horizontal plane. Thereafter, the movable plate 12d of the transport mechanism 12a stops from the reverse limit position to the forward limit position, and returns to the normal state in which the game board 5 from the conveyor 6 is transported in the transport direction X. This normal state is a mode in which the board stopper 12f stops at the retreat limit position and retreats from the transport path of the game board 5.
[0019]
In short, according to the discharging device 12, when the gaming board 5 recognized as defective is transferred from the conveyor 6 to the transport mechanism 12a and received by the board stopper 12f and stopped, the receiving body 12j of the delivery mechanism 12h is turned into the gaming board 5. Dive under. When the movable plate 12d of the transport mechanism 12a moves backward, the game board 5 falls from between the front and rear directions of the roller 12e of the transport mechanism 12a and is received by the receiver 12j. Thereafter, when the receiving body 12j moves backward and the game board 5 falls from between the front and rear directions of the receiving body 12j, the abutting rod 12k of the delivery mechanism 12h prevents the game board 5 from being accompanied with the receiving body 12j. The game board 5 can be dropped horizontally.
[0020]
The falling game board 5 is stacked by a lift mechanism (not shown) provided below the transport mechanism 12a and formed into a block, or obliquely downward by a shooter (not shown) provided below the transport mechanism 12a. It is possible to slide down.
[0021]
Further, in FIG. 2, the nail driving device 13 in the nail driving step 4 is disposed on a pair of chain conveyors 13 a that are opposed to each other at a predetermined interval in the front-rear direction orthogonal to the transport direction X, and on the side of the chain conveyor 13 a. The non-defective game board 5 is conveyed in the transport direction X by the chain conveyor 13a via the discharge device 12, and the game board 5 corresponds to the table 13c of the nailing machine 13b. When the game board 5 is reached, the transport of the game board 5 is regulated by a substrate stopper (not shown), and the game board 5 whose transportation is stopped is transferred and mounted on the table 13c by a carry-in loading mechanism (not shown). The game board 5 is positioned and mounted on the table 13c by externally fitting the reference holes 5d to positioning pins 13d provided on the table 13c. Either a gaming board sensor (not shown) that detects that the gaming board 5 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, is a gaming board. By outputting the type signal and the nail driving start signal to a control unit (not shown) in which the computer is built, the computer stores the nail data corresponding to the model of the game board 5 stored in advance in the storage device of the control unit. The nail driving position and order are extracted, and the table 13c is moved in the X and Y directions as the vertical and horizontal directions in the plane according to the driving position and order, and the predetermined position of the game board 5 is determined. The positioning is stopped below the nail holder mechanism (not shown) and the hammer mechanism (not shown) attached to the upper set plate 13e. And by driving a nail (not shown) supplied to the nail holder mechanism from a nail supply unit 13f such as a parts feeder into the game board 5 with a hammer mechanism, a large number of nails to be hit on one game board 5 are obtained. The game board 5 is automatically driven one by one. Next, when the driving of the predetermined number of nails is completed, the game board 5 on which the nails are driven by the unloading loading mechanism (not shown) is removed from the table 13c and transferred to the chain conveyor 13a or the unloading conveyor (not shown). Transport to the next process.
[0022]
In the nailing machine 13b, the case where the set plate 13e is stationary and the table 13c is driven has been illustrated and described. However, the table 13c is stationary and the set plate 13e is driven, and the nail holder mechanism and the hammer mechanism are separated. The same can be done by moving the set in the XY direction, or moving the table 13c in the X direction and moving the set of the nail holder mechanism and the hammer mechanism in the Y direction by the set plate 13e. In this case, if the nail supply part 13g is assembled to the set plate 13e and moved in the same manner as the group consisting of the nail holder mechanism and the hammer mechanism, the nail supply operation to the nail holder mechanism becomes smooth.
[0023]
As the warp inspection device 11, as shown in FIGS. 5 and 6, a sensor 15 such as a proximity sensor, a photoelectric sensor, or a limit switch that reacts when wood or synthetic resin is present in the measurement range is fixed on the upper side. A plurality of upper and lower sensors 15 are turned on or off in a state in which a plurality of plates 11c and a lift base 11n are provided with a plurality of relative heels and supported by upper support pins 11f and lower support pins 11q as shown in FIG. If the game board 5 is in the same operating state, it is determined that the game board 5 is not warped, and as shown in FIG. A double-sided inspection for determining that the board 5 is warped is also possible. In this case, since the presence / absence of warpage is detected when the on / off operations of the upper and lower sensors 15 are the same or in conflict, the displacement amount from the reference point, the difference between the displacement amount and the reference point, and the difference are allowable. It is not necessary to electrically process whether it is included in the range, and the apparatus can be simplified.
[0024]
Further, as shown in FIG. 7, the warp inspection device 11 is provided with a shaft 16 coaxially spaced above the center point (i) of either the upper fixing plate 11c or the lift base 11n. If the sensor 11d or the sensor 15 is attached to the tip of the arm 17 protruding in the direction and the shaft 16 is electrically rotated to rotate the sensor 11d or the sensor 15 with respect to the game board 5, one sensor Warpage can be detected by 11d or one sensor 15.
[0025]
The sensor 11d can be similarly applied to a non-contact type using light such as a laser or LED.
[0026]
In the above embodiment, the warpage of the game board 5 is electrically detected. However, when the game board 5 is supplied to the nail driving process 4, it is artificially detected whether the game board 5 is warped. Even if only the non-defective game board 5 with a warp out of the standard is supplied to the nail driving process 4 and only the non-defective game board 5 as a non-standard game board 5 is supplied to the nail driving process 4, the same applies.
[0027]
Furthermore, in the above-described embodiment, the defective game board 5 is automatically discharged from the conveyance process to the nail driving process 4 according to the result of the warp detection. It is also possible to generate an alarm such as voice, image, sound, etc., and to reject defective products artificially by the alarm.
