Patent

CA 2099652

The present invention teaches method and apparatus for a single stroke kinematic system, having a required mid stroke dwell, which permits positioning of the mid strike dwell with respect to both space and time. A four bar linkage mechanism is disclosed having a bottom stroke and a top stroke toggle thereby kinematically providing the acceleration ramps into and out of the bottom stroke and top stroke dwells. A cycloidal drive mechanism is provided to drive the four bar linkage and providing time/phase shifting of the cycloidal drive's mid cycle dwell.

Méthode et matériel pour un système cinématique à course unique, qui a un temps d'arrêt obligatoire à mi-course, réglable dans l'espace et dans le temps. Une tringlerie à quatre bielles, qui a une bascule de fin de course supérieure et de fin de course inférieure, permet de produire cinématiquement des rampes d'accélération en direction et en provenance des fins de course inférieure et supérieure. Un entraînement cycloïdal entraîne la tringlerie à quatre bielles et assure le décalage de temps/phase de l'arrêt de mi-cycle de l'entraînement cycloïdal.
