Description

【0001】
【発明の属する技術分野】
この発明は、パチンコ機等のような遊技機を製造する過程で、遊技基板に意匠図の描かれた化粧シートを接着する装置に関する。
【0002】
【従来の技術】
パチンコ機を製造する際の化粧シート貼付装置では、コンベアで遊技基板を一方向に搬送し、その搬送方向の上流側より下流側に順に、遊技基板を温め、その遊技基板の片側表面としての上面に接着剤を塗布し、その上に意匠盤面としての化粧シートを位置決め搭載した後に、化粧シートと遊技基板とを互いに近づく方向に加圧して接着剤で投錨結合している。
【0003】
【発明が解決しようとする課題】
しかし、周囲の温度や湿度の変化により、化粧シートが搭載される際の接着剤の乾き具合にばらつきを生じて、貼付後に化粧シートが剥がれることがある。このようなことから、時々刻々と変化する周囲の温度や湿度を基に、作業者の経験により、遊技基板を温める温度や時間、接着剤の濃さや塗る厚さ、化粧シートと遊技基板とを互いに近づく方向に加圧する力や時間等に関係する装置機能部分を調整しているが、その調整に多大な労力と時間とを要するうえ、作業者の経験差や調整回数差又は調整作業間隔差等により、貼付後の化粧シートの剥がれを生じることを否めなかった。
【0004】
そこで、この発明は、化粧シートが搭載される際の接着剤の乾き具合を一様に調整して、品質信頼性及び生産効率を向上できる化粧シート貼付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】
本発明に係る遊技機製造用化粧シート貼付装置は、コンベアで遊技基板を搬送する搬送方向の上流側より下流側に順に、ホットプレス機構、糊付機構、化粧シート貼合機構、コールドプレス機構を配置し、ホットプレス機構よりコールドプレス機構まで遊技基板を順送りすることにより、ホットプレス機構がホットプレートを遊技基板の上面に押し付けて遊技基板の上面を温め、糊付機構が転写ロールとドクターロールとで形成された上部空間に溜められた接着剤を転写ロールの回転によってホットプレス機構で温められた遊技基板の上面に接着剤を塗布し、化粧シート貼合機構が糊付機構で遊技基板の上面に塗布された接着剤に意匠盤面を構成する化粧シートを搭載し、コールドプレス機構が化粧シート貼合機構から搬送された化粧シートと遊技基板とを互いに近づく方向に加圧して接着剤で結合し、遊技基板と化粧シートとからなる遊技盤を形成する遊技機製造用化粧シート貼付装置において、ホットプレス機構のホットプレートに発熱用の電力を供給したり遮断したりするスイッチと、糊付機構の転写ロールとドクターロールとで形成された上部空間に溜められた接着剤に溶剤としての水を滴下供給するパイプと、パイプに水を供給したり遮断したりするバルブと、遊技基板の上面に塗られた接着剤の表面温度を非接触に検温する温度計と、温度計から出力された検出温度によりバルブとスイッチとを制御する処理手段とを備えたことを特徴としている。本発明に係る遊技機製造用化粧シート貼付装置によれば、温度計によって遊技基板に塗られた接着剤の検出された表面温度に応じてホットプレス機構のホットプレートに発熱用の電力を供給したり遮断したりするスイッチと糊付機構の転写ロールとドクターロールとで形成された上部空間に溜められた接着剤に溶剤としての水を滴下供給するパイプに水を供給したり遮断したりするバルブとを制御して、化粧シートが搭載される際の接着剤の乾き具合を一様に調整することにより、貼付後の化粧シートの剥がれを防止して、品質信頼性及び生産効率を向上できる。処理手段がホットプレートで遊技基板の上面を温める時間、転写ロールで遊技基板の上面に塗布される接着剤の厚さ、コールドプレス機構で化粧シートと遊技基板とを互いに近づく方向に加圧する力や時間、コンベアで遊技基板を搬送する速度の1つまたは複数又は全部を制御すれば、化粧シートが搭載される際の接着剤の乾き具合を一層一様に調整することができる。
【0006】
【発明の実施の形態】
図1〜2は一実施形態を示している。図1に示すように、検査工程1において、遊技基板2の厚さ、外形、反り等が規格に収まるかを検査し、規格内の遊技基板2を良品として次工程である化粧シート貼工程3に供給し、規格外の遊技基板2を不良品として製造工程より外す。化粧シート貼工程3での化粧シート貼付装置4では、チェーンやローラー又はベルト等のいずれか1つ又は2つ以上を組み合わせて構成された図外のコンベアが遊技基板2を一方向に搬送する過程で、ホットプレス機構5が遊技基板2の上面を温め、糊付機構7が遊技基板2の温められた上面に接着剤を塗り、乾燥度調整手段12中の表面温度検出機構7が遊技基板2に塗られた接着剤の表面温度を非接触に検出し、化粧シート貼合機構8が遊技基板2の接着剤が付いた上面に意匠盤面としての化粧シート9を位置決め搭載し、コールドプレス機構10が化粧シート9と遊技基板2とを常温の加圧体で互いに近づく方向に押し付けて接着する。乾燥度調整手段12中の処理手段11は前記検出温度に応じて化粧シート9の搭載される際の接着剤の乾き具合が一様となるように装置機能部分としての例えば前記コンベア、ホットプレス機構5、糊付機構6等の1つ又は複数又は全部を電気的に制御する。
【0007】
図2にも示すように、ホットプレス機構5は、無端状のチェーンコンベア5aが一方向に回転・停止を間欠的に行うことで、チェーンコンベア5aの回転方向に所定間隔を以てチェーンコンベア5aに設けられた送爪5bで遊技基板2を搬送方向X(前記一方向と同じ方向)に移動・停止を繰り返して順に送る。この移動する送爪5bで押された遊技基板2が下側の固定盤5cの上に搭載されると、チェーンコンベア5aが所定時間停止し、その停止中に、上側のホットプレート5dが昇降し、その下降にてホットプレート5dが遊技基板2を固定盤5cとで挟み付けて遊技基板2の上面を温める。そして、ホットプレート5dが上昇すると、チェーンコンベア5aが再び回転・停止を行って、温められた遊技基板2を下流側に搬送し、次の遊技基板2を固定盤5cに搭載して停止する。このチェーンコンベア5aの回転・停止と、ホットプレート5dの昇降とを繰り返すことにより、複数の遊技基板2を順送りしながら温めた後に糊付機構5に排出する。ホットプレート5dに内蔵された発熱体5eは、スイッチ5fを介して電力供給系統5gに接続している。
【0008】
糊付機構6は、複数のローラーを搬送方向Xに所定間隔を以て並列配置したローラーコンベア6aが一方向に回転駆動することで、ホットプレート機構5に引き続き遊技基板2を搬送方向Xに搭載搬送する。このローラーコンベア6aに内蔵された1つのドライブロール6bの上方には、ドライブロール6bと逆方向に同一の周速度で回転駆動する転写ロール6cと、これに接触又は近接するように可動支持されたドクターロール6dとを配置し、転写ロール6bとドクターロール6cとの間に形成された側面視略V字形の上部空間にエマルジョンタイプの接着剤6eを溜め、ドライブロール6bを含むローラーコンベア6aを回転駆動すると共に、転写ロール6bとドクターロール6cとを逆方向に周速度に差を持たせて回転駆動することにより、接着剤6eが転写ロール6cの外周面に転写ロール6cとドクターロール6dとの調整された軸間距離による所定厚さで均一に付着し、ドライブロール6bと転写ロール6cとがその間に遊技基板2を引き込むように通過させる過程で、転写ロール6cが遊技基板2の上面に接着剤6eを転写塗布する。前記転写ロール6cとドクターロール6dとで形成された上部空間に溜められた接着剤6eは、貯留量検出による電気的な制御か、又は作業者の経験則により、図外の供給系統より適宜補給される。この接着剤6eの上方には、接着剤6eの濃さ(粘度)を調整するための溶剤としての水を接着剤6eに滴下供給するパイプ6fを配置し、パイプ6fにはバルブ6gを介して水供給系統6hを接続してある。
【0009】
転写ロール6cよりも下流側には赤外線温度計7aをローラーコンベア6aで搬送される遊技基板2よりも上方に離隔配置し、赤外線温度計7aが遊技基板2の上面に塗られた接着剤6eより発する赤外線を感知して当該接着剤6eの表面温度を非接触に検温し、その検出した温度を電気信号として変換して処理手段11に出力する。
【0010】
この実施形態の場合、処理手段11は、赤外線温度計7aからの検出温度を処理手段11に予め設定された上限温度と比較し、検出温度が上限温度以上の場合はスイッチ5fをオフ動作して電力供給系統5gから発熱体5eへの電力供給を遮断し、検出温度が上限温度未満の場合はスイッチ5fをオン動作して電力供給系統5gから発熱体5eへの電力供給を投入することにより、ホットプレート5dの温度を制御する。前記上限温度は、化粧シート貼付装置の周囲の温度や湿度、遊技基板2に塗られた接着剤6eの厚さ、接着剤6eの濃さ、転写ロール6cから検温するまで経過時間、コンベアの搬送速度、赤外線温度計7aの固有な特性より、貼付後の化粧シート9が遊技基板2より剥がれることがない温度をサンプリングして定められる値である。又、処理手段11は赤外線温度計7aからの検出温度を処理手段11に予め設定された知識情報に照合し、その検出温度に対応する加水量を抽出し、その加水量を電気信号に変換してバルブ6gに出力して、バルブ6gの開度量を調整し、加水量に相当する水をパイプ6fから接着剤6eに加えることにより、接着剤6eの濃さを制御する。前記知識情報は、化粧シート貼付装置の周囲の温度や湿度、遊技基板2に塗られた接着剤6eの厚さ、接着剤6eの濃さ、転写ロール6cから検温するまで経過時間、コンベアの搬送速度、赤外線温度計7aの固有な特性より、貼付後の化粧シート9が遊技基板2より剥がれることがない加水量をサンプリングして、検出温度と加水量との関係を規定したものである。
【0011】
尚、図1の表面温度検出機構7は図2の赤外線温度計7aを設置位置に支持する図外の機構を含めた概念を表現している。
【0012】
この実施形態によれば、ホットプレス機構5で温められた遊技基板2の上面に、糊付機構6で接着剤6eを塗布した後に、乾燥度調整手段12で検出された接着剤6eの表面温度に応じてホットプレート5dの表面温度や接着剤6eの濃さの一方又は両方を制御して、化粧シート9が搭載される際の接着剤6eの乾き具合を一様に調整しているので、貼付後の化粧シート9の剥がれを防止して、品質信頼性及び生産効率を向上することができる。
【0013】
又、乾燥度調整手段12が遊技基板2に塗られた接着剤6eの表面温度を非接触に検出するので、接着剤6eの厚さや表面性状を適正に維持して、検温することができる。
【0014】
前記実施形態では、処理手段11でホットプレート5dの温度制御と接着剤6eの濃さ制御とを行う場合を図示して説明したが、これらの制御に加えるか、又はこれらの制御以外に、処理手段11で遊技基板2を温める時間、接着剤6eを塗る厚さ、化粧シート9と遊技基板2とを互いに近づく方向に加圧する力や時間、コンベアの搬送速度等の1つ又は複数又は全部に関係する装置機能部分を制御しても同様の作用効果がある。
【0015】
前記実施形態では、接着剤6eの乾き具合を一様に制御する条件として、遊技基板2に塗られた接着剤6eの表面温度のみを採用したが、化粧シート貼付装置4の周囲の湿度を検出し、その検出湿度も加えれば、上記制御の精度を、より一層向上できる。
【0016】
前記実施形態では、ホットプレス機構5において、遊技基板2を1回だけ温めて糊付機構6に送るような形態を図示して説明したが、搬送方向Xに隣接する複数の遊技基板2を覆う大きさにホットプレート5dを形成し、チェーンコンベア5aが回転・停止の間欠動作を複数回行う各停止中毎に、ホットプレート5dが昇降を1回行うことで1つの遊技基板2を2回又はそれ以上の回数温めて糊付機構6に送るようにすれば、ホットプレート5dの温度を高くしなくても、1つの遊技基板2が化粧シート貼付装置4を通過する作業時間(タクト)を短縮することができる。この場合、ホットプレート5dが覆う遊技基板2の数に合わせて、発熱体5eをブロック化し、上流側のブロックを下流側のブロックより高温となるような温度制御を行えば、初めて温められる遊技基板2でホットプレート5dが冷えてしまうことがなく、遊技基板2を適切に加熱することができる。この温度制御での高温低温は相対的な温度で、高温でもホットプレート5dが遊技基板2に接触している間に、遊技基板2が焦げない程度の温度であり、何度に設定するかは、ホットプレート5dを遊技基板2に実際に押し付けている加熱動作時間との関係による。この発熱体5eをブロック化した際に、処理手段11で高温側のブロックを低温側のブロックに優先して温度制御すれば、ホットプレート5dの冷え過ぎを阻止できる。

One or more or all of the gluing mechanism 6 and the like are electrically controlled.
[0007]
As shown also in FIG. 2, the hot press mechanism 5 is provided on the chain conveyor 5a at a predetermined interval in the rotation direction of the chain conveyor 5a by intermittently rotating and stopping the endless chain conveyor 5a in one direction. The game board 2 is repeatedly moved and stopped in the transport direction X (the same direction as the one direction) with the feed claws 5b that are sent in order. When the game board 2 pushed by the moving claw 5b is mounted on the lower fixed platen 5c, the chain conveyor 5a stops for a predetermined time, and the upper hot plate 5d moves up and down during the stoppage. Then, the hot plate 5d sandwiches the game board 2 with the stationary platen 5c and warms the upper surface of the game board 2. When the hot plate 5d rises, the chain conveyor 5a rotates and stops again, transports the warmed game board 2 to the downstream side, mounts the next game board 2 on the stationary platen 5c, and stops. By repeating the rotation / stop of the chain conveyor 5a and the raising / lowering of the hot plate 5d, the plurality of game boards 2 are heated while being sequentially fed and then discharged to the gluing mechanism 5. The heating element 5e built in the hot plate 5d is connected to the power supply system 5g via the switch 5f.
[0008]
The gluing mechanism 6 mounts and transports the game board 2 in the transport direction X following the hot plate mechanism 5 when a roller conveyor 6a in which a plurality of rollers are arranged in parallel in the transport direction X with a predetermined interval is rotationally driven in one direction. . Above one drive roll 6b built in the roller conveyor 6a, a transfer roll 6c that is rotationally driven at the same peripheral speed in the opposite direction to the drive roll 6b, and is movably supported so as to be in contact with or close to the transfer roll 6c. A doctor roll 6d is arranged, and an emulsion type adhesive 6e is accumulated in a substantially V-shaped upper space formed between the transfer roll 6b and the doctor roll 6c, and the roller conveyor 6a including the drive roll 6b is rotated. In addition to being driven, the transfer roll 6b and the doctor roll 6c are rotationally driven in the opposite directions with a difference in peripheral speed, whereby the adhesive 6e is placed between the transfer roll 6c and the doctor roll 6d on the outer peripheral surface of the transfer roll 6c. It adheres uniformly with a predetermined thickness according to the adjusted inter-axis distance, and the drive roll 6b and the transfer roll 6c are in between the game board 2 In the course of passing to pull the transfer roll 6c is transferred applying adhesive 6e on the upper surface of the game board 2. The adhesive 6e stored in the upper space formed by the transfer roll 6c and the doctor roll 6d is appropriately replenished from an unillustrated supply system by electrical control based on the detection of the storage amount or by an operator's empirical rule. Is done. Above this adhesive 6e, a pipe 6f for supplying water as a solvent for adjusting the concentration (viscosity) of the adhesive 6e dropwise to the adhesive 6e is disposed, and the pipe 6f is connected via a valve 6g. A water supply system 6h is connected.
[0009]
An infrared thermometer 7a is arranged on the downstream side of the transfer roll 6c so as to be spaced apart from the game board 2 conveyed by the roller conveyor 6a, and the infrared thermometer 7a is made of an adhesive 6e applied to the upper surface of the game board 2. The surface temperature of the adhesive 6e is detected in a non-contact manner by detecting the emitted infrared rays, and the detected temperature is converted as an electrical signal and output to the processing means 11.
[0010]
In the case of this embodiment, the processing means 11 compares the detected temperature from the infrared thermometer 7a with the upper limit temperature preset in the processing means 11, and when the detected temperature is equal to or higher than the upper limit temperature, the switch 5f is turned off. By shutting off the power supply from the power supply system 5g to the heating element 5e and turning on the switch 5f when the detected temperature is lower than the upper limit temperature, the power supply system 5g turns on the power supply to the heating element 5e, The temperature of the hot plate 5d is controlled. The upper limit temperature includes the ambient temperature and humidity of the decorative sheet sticking device, the thickness of the adhesive 6e applied to the game board 2, the density of the adhesive 6e, the elapsed time until the temperature is detected from the transfer roll 6c, and the conveyance of the conveyor The value is determined by sampling the temperature at which the decorative sheet 9 is not peeled off from the game board 2 due to the speed and the specific characteristics of the infrared thermometer 7a. The processing means 11 compares the detected temperature from the infrared thermometer 7a with knowledge information preset in the processing means 11, extracts the amount of water corresponding to the detected temperature, and converts the amount of water into an electrical signal. The amount of opening of the valve 6g is adjusted, and the amount of water corresponding to the amount of water added is added to the adhesive 6e from the pipe 6f, thereby controlling the strength of the adhesive 6e. The knowledge information includes the ambient temperature and humidity of the decorative sheet sticking device, the thickness of the adhesive 6e applied to the game board 2, the density of the adhesive 6e, the elapsed time until the temperature is detected from the transfer roll 6c, and the conveyance of the conveyor The amount of water that does not cause the decorative sheet 9 to be peeled off from the game board 2 is sampled based on the speed and the unique characteristics of the infrared thermometer 7a, and the relationship between the detected temperature and the amount of water is defined.
[0011]
The surface temperature detection mechanism 7 in FIG. 1 expresses a concept including a mechanism (not shown) that supports the infrared thermometer 7a in FIG. 2 at the installation position.
[0012]
According to this embodiment, after the adhesive 6e is applied by the gluing mechanism 6 to the upper surface of the game board 2 warmed by the hot press mechanism 5, the surface temperature of the adhesive 6e detected by the dryness adjusting means 12 is detected. Accordingly, by controlling one or both of the surface temperature of the hot plate 5d and the strength of the adhesive 6e, the degree of drying of the adhesive 6e when the decorative sheet 9 is mounted is uniformly adjusted. It is possible to prevent the decorative sheet 9 from being peeled off and improve quality reliability and production efficiency.
[0013]
Further, since the dryness adjusting means 12 detects the surface temperature of the adhesive 6e applied to the game board 2 in a non-contact manner, the thickness and surface properties of the adhesive 6e can be properly maintained and the temperature can be measured.
[0014]
In the above embodiment, the case where the processing means 11 performs the temperature control of the hot plate 5d and the density control of the adhesive 6e has been illustrated and described. However, in addition to these controls, in addition to these controls, the processing One or more or all of the time for warming the game board 2 by means 11, the thickness for applying the adhesive 6e, the force and time for pressing the decorative sheet 9 and the game board 2 in the direction approaching each other, the conveying speed of the conveyor, etc. Control of related apparatus function parts has the same effect.
[0015]
In the above embodiment, only the surface temperature of the adhesive 6e applied to the game board 2 is used as a condition for uniformly controlling the drying condition of the adhesive 6e, but the humidity around the decorative sheet pasting device 4 is detected. If the detected humidity is also added, the accuracy of the control can be further improved.
[0016]
In the above-described embodiment, the hot press mechanism 5 has been described with reference to a mode in which the game board 2 is heated once and sent to the gluing mechanism 6, but covers a plurality of game boards 2 adjacent in the transport direction X. The hot plate 5d is formed in a size, and the chain conveyor 5a performs intermittent operation of rotation / stop a plurality of times. Each time the hot plate 5d moves up and down once, the game board 2 is moved twice or twice. If it is heated more times and sent to the gluing mechanism 6, the work time (tact) for one game board 2 to pass through the decorative sheet sticking device 4 can be shortened without increasing the temperature of the hot plate 5d. can do. In this case, if the heating element 5e is blocked in accordance with the number of game boards 2 covered by the hot plate 5d and the temperature control is performed so that the upstream block becomes higher than the downstream block, the game board can be heated for the first time. 2, the hot plate 5 d is not cooled, and the game board 2 can be heated appropriately. The high temperature and low temperature in this temperature control is a relative temperature, and is a temperature at which the game board 2 does not burn while the hot plate 5d is in contact with the game board 2 even at high temperature. This depends on the relationship with the heating operation time during which the hot plate 5d is actually pressed against the game board 2. When the heating element 5e is made into a block, if the processing means 11 controls the temperature of the high-temperature block in preference to the low-temperature block, the hot plate 5d can be prevented from being overcooled.
