本発明は、回転運動を往復運動に変換する装置に係り、
詳しくはチェーン等の巻掛は体を用いた長円クランク装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for converting rotational motion into reciprocating motion,
Specifically, it relates to an oval crank device that uses the body to wrap a chain or the like.
従来、クランク装置は、軸に対して偏心位置にクランク
ピンを設置し、該クランクピンの回転によってスライダ
ー等に往復運動を与えていた。Conventionally, a crank device has a crank pin installed at an eccentric position with respect to a shaft, and rotation of the crank pin gives reciprocating motion to a slider or the like.
このため、スライダーの往復運動量は、クランクピンの
偏心量の２倍でしかなく、該往復運動量を増大しようと
すれば、ピン偏心量を大きく設定しなければならず、物
品搬送装置等の比較的長いストロークを必要とするもの
に適用する場合、装置が極めて大型化し、設置スペース
等で困難を生じていた。Therefore, the amount of reciprocating motion of the slider is only twice the amount of eccentricity of the crank pin, and in order to increase the amount of reciprocating movement, the amount of eccentricity of the pin must be set large, which makes it relatively difficult for goods conveying devices, etc. When applied to something that requires a long stroke, the device becomes extremely large, creating difficulties in terms of installation space, etc.
また、物品搬送装置等では、合理的な運動曲線による高
速化、及び早戻り機構による搬送タクトの短縮化が望ま
れているが、従来の長尺送り機構では、運動曲線が滑ら
かでなく、送り開始及び停止時に大きな加速を生じ、高
速化が困難であると共に、早戻り機構を介在すると機構
が極めて複雑になり、高価になっていた。In addition, in article conveyance devices, etc., it is desired to increase the speed with a rational motion curve and shorten the conveyance tact with a quick return mechanism, but with conventional long-length feed mechanisms, the motion curve is not smooth and the A large acceleration occurs when starting and stopping, making it difficult to increase the speed, and if a quick return mechanism is involved, the mechanism becomes extremely complex and expensive.
そこで、本発明は、２個の回転体に無端状の巻掛は体を

掛は体に連結板を介してスライダーを連結して構成し、
もって上述欠点を解消した長円クランク装置を提供する
ことを目的とするものである。Therefore, in the present invention, an endless winding body is wound around two rotating bodies, and an intermediate rotating body is rolled into contact with one side of the body, and the body side of the winding body is bent. , the winding is configured such that the body side part is linear and the winding is longer than the other body side part, and the winding is configured by connecting a slider to the body via a connecting plate,
The object of the present invention is to provide an oval crank device which eliminates the above-mentioned drawbacks.
