Claims

[Scope of utility model registration request]

A manual attachment/detachment mechanism that manually attaches and detaches the fixing roller to and from the printing plate by rotating the roller lifting shaft, and a manual attachment/detachment mechanism that transmits the rotation of the stop shaft for attaching and detaching the printing cylinder to the roller lifting shaft, and moves the forming roller relative to the printing plate. In a roller attachment/detachment device for a rotary printing press that includes an automatic attachment/detachment mechanism and a manual/automatic switching mechanism, an operating handle for the manual attachment/detachment mechanism is fixed to the roller raising shaft, and the stop shaft;
The rotation transmission mechanism between the roller raising shafts includes a roller raising lever fixed to the stop shaft, a lever with a pin fixed to the roller raising shaft, and a groove that engages with the pin of the lever with the pin. a rod pivotally attached to the free end of the raising lever, and the manual/automatic switching mechanism is configured by a switching handle rotatably supported on the frame side, and a switching handle in the direction of engaging the groove and the pin. a spring member that applies rotational force to the rod; and a spring member that is supported on the switching handle side and engages the rod when the switching handle rotates toward the manual attachment/detachment side, and disengages the rod from the groove and the pin. 1. A roller attachment/detachment device for a rotary printing press, comprising a transmission member that rotates the roller.
