DEVICE FOR ITEMS TRANSMISSION Russian patent published in 2012 - IPC B25J18/04 

FIELD: machine building industry.

SUBSTANCE: invention relates to mechanisms with complicated movement of output elements, which are used for servicing process machines, presses and etc. The device comprises a multi-element transmission gear with an output element, actuator with output elements provided with fingers for gripping items, and a drive. The transmission gear includes a crank-and-rocker mechanism with rocker being cinematically coupled with the output element by means of a system of intermediate elements including flexibly connected together coupler link, sliding element and gear wheels. The sliding element is provided with a rack rod to couple with one of gear wheels. The other gear wheel is coupled with rack rod fixed on the output element which is a driving member of the actuator. The gear wheels are fixed rigidly and in axial alignment with one of the axis and have different diameters of a pitch circle. The gear wheel coupled with a rack rod of sliding element is a wheel of smaller diameter, while the gear wheel of larger diameter is a quick-detachable element. Each output element of the actuator is provided with a elastic load-bearing element and thrust block for fixed position on the output element of transmission gear. The device is provided with collapsible wedges for interacting with output elements of actuator at the end of runs.

EFFECT: invention allows for fast adjustment of output elements to given value of linear runs.
