本発明は、特に輪転式印刷機におけるカム制御形給紙機
構の駆動装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drive device for a cam-controlled paper feed mechanism, in particular in a rotary printing press.
輪転式印刷機は一つあるいは複数の印刷部から成ってお
り、その場合初めの印刷部に紙差し板が付属され、整合
流で静止した状態にある紙はこの紙差し板から周期的に
作動する給紙機構のグラブによってつかまれ、機械速度
まで加速され、回転するシリンダ（給紙ドラム）に受は
渡される。A rotary printing press consists of one or more printing stations, the first printing station being attached to a paper feed plate from which the paper, which is stationary in a consistent flow, is moved periodically. The tray is grabbed by the grab of the feed mechanism, accelerated to machine speed, and passed to a rotating cylinder (feed drum).
給紙機構の駆動装置は、不規則伝動装置から構成されて
おり、歯車系を介して印刷機の印刷部に接続されている
。The drive of the paper feed mechanism consists of a random transmission and is connected to the printing section of the printing press via a gear system.
給紙機構の周期的な作動は、周期的に変動するトルクを
必要とし、この変動するトルクは給紙機構に振動を生じ
させ、歯車系を介して印刷部に導かれてしまう。この振
動は整合ミスを生じたり二重になってしまい、そのため
は印刷の質が悪くなったり不良品を生じてしまう。The periodic operation of the paper feed mechanism requires a periodically varying torque that causes vibrations in the paper feed mechanism that are directed through the gear system to the printing station. This vibration can cause misalignment or duplication, resulting in poor print quality and defective products.
この問題を解消するために、非弾性的な補助ロータ（Ｂ
ｅｔ Ｉａｕｆ’ｅｒ）によってフランク面の連続した
接触を保証して、印刷の質を向上することが知られてい
る。しかしこの非弾性的な補助ロータは、単一の大きさ
のシリンダを持った印刷機にしか利用できない。To solve this problem, an inelastic auxiliary rotor (B
et Iauf'er) to ensure continuous contact of the flank surfaces and improve the quality of printing. However, this inelastic auxiliary rotor can only be used in printing presses with a single size cylinder.
周期的に作動する機構において歯車のフランク面を確実
に接触させるために、弾性的な補助ロータを使用するこ
とも知られている。しかしこの補助ロータは最大機械回
転数に応じて設計しなければならず、これはすべての回
転数において歯車に大きな応力を生じさせ、このために
激しい摩耗を生ずる。更にこの弾性的な補助ロータは非
常に低い動力までしか歯車のフランク面の確実な接触を
行えず、大きな構造空間を必要とする。It is also known to use elastic auxiliary rotors to ensure contact of the flank surfaces of gear wheels in cyclically operated mechanisms. However, this auxiliary rotor has to be designed according to the maximum machine speed, which causes high stresses on the gear wheels at all speeds, which leads to severe wear. Moreover, this elastic auxiliary rotor can only provide reliable contact of the flank surfaces of the gear wheels up to very low powers and requires a large amount of construction space.
更に弾性的な補助ロータおよび非弾性的な補助ロータは
、所定の範囲において歯車のバイアス圧によってフラン
ク面の連続した接触を可能にするが、そのバイアス圧に
よって摩耗が増大するという共通した欠点を有している
。更に補助ロータによって整合（Ａｎ ｌ ａｇｅｐａ
ｓｓｅｒ）へのトルク変動の影響が除去されるだけで、
そのトルクが後続の印刷機に伝わること、および印刷の
質に悪影響を及ぼすことは防止できない。In addition, elastic and inelastic auxiliary rotors allow continuous contact of the flank surfaces in a given range due to the gear bias pressure, but they have the common disadvantage that the bias pressure increases wear. are doing. Furthermore, alignment is performed by an auxiliary rotor (An l agepa
sser) is simply removed,
It is impossible to prevent that torque from being transmitted to subsequent printing presses and having an adverse effect on print quality.
トルクの需要ないしトルクの変動を直接制御することも
知られている。そのためにしばしばはずみ車が利用され
るが、これは圧胴、ゴム胴および版胴の既存の質量に基
づいて、特別な場合には使用できない程の非常に大きな
寸法にしなければならない。Direct control of torque demand or torque variations is also known. For this purpose, flywheels are often used, but due to the existing masses of the impression, blanket and form cylinders, these have to be of very large dimensions, so that they cannot be used in special cases.
更に摺動クランク伝動装置として形成されたトルク平衡
伝動装置が知られているが、これはその上死点および下
死点に基づいて、周期的に作動する給紙機構には適用で
きない。というのはトルク特性の時間的経過が必要な領
域（Ｍａｓｚ）において変化しないからである。更に印
刷機においては、未臨界範囲で作動するので、追加的に
狂いが生ずる。Furthermore, torque-balancing transmissions are known which are designed as sliding crank transmissions, but because of their top dead center and bottom dead center, they cannot be applied to cyclically operating paper feed mechanisms. This is because the time course of the torque characteristics does not change in the required region (Masz). Furthermore, printing presses operate in a subcritical range, resulting in additional deviations.
トルクを平衡するためにばね補償器も知られているが、
これは常に最大回転数に対して設計されており、このこ
とは大きな摩耗を伴い、その回転数以下においては機構
に振動が生ずる。従ってこれも給紙機構に適用できない
。Spring compensators are also known to balance the torque;
It is always designed for a maximum rotational speed, which is accompanied by high wear, and below which rotational speed vibrations occur in the mechanism. Therefore, this also cannot be applied to the paper feeding mechanism.
更に理想的にカム制御されるトルク平衡伝動装置が知ら
れているが、その印刷機への採用は示唆されていない。Further, ideally cam-controlled torque balance transmission devices are known, but their use in printing presses has not been suggested.
本発明の目的は、カム制御形給紙機構の駆動装置を、印
刷の質を向上し、印刷機の摩耗を低下し、汎用的に採用
できるように作ることにある。SUMMARY OF THE INVENTION It is an object of the present invention to create a drive for a cam-controlled feed mechanism that improves printing quality, reduces press wear, and is universally applicable.
本発明の課題は、給紙機構の駆動装置を、その機構に振
動が生ずることなしに、トルク変動の大きさを最小にす
るように作ることにある。SUMMARY OF THE INVENTION It is an object of the present invention to create a drive device for a paper feed mechanism in such a way that the magnitude of torque fluctuations is minimized without vibrations occurring in the mechanism.
