A digitally indexed reciprocating linear actuator includes a frame and a servomotor mounted to the frame. A crank is gear-coupled with integer gear ratio to the servomotor for unidirectional rotation. An actuator slide with a non-home index point is slideably-mounted to the frame for linear motion. A connecting rod couples the crank to the actuator slide. The actuator also includes means, including a sensor, for detecting the index point at two angular positions of the crank. A wrapping machine for wrapping a plurality of articles has repeated cycles of article-handling operations and a plurality of carriages, each carriage capable of moving at least one article for wrapping. The wrapping machine includes at least one digitally indexed reciprocating linear actuator having a crank, and an actuator slide with a non-home index point. The wrapping machine records first and second servomotor angular positions on detecting the index point at first and second angular positions of the crank. The wrapping machine identifies home position as an angular position midway between the first and second positions.

Reciprocating linear actuator

A cyclical machine for forming at least one glass container each machine cycle comprising a plurality of controllers for controlling regulators and/or profiled motion actuators, at least one displaceable structure, controllers controlling the operation of all the other controllers, each of the controllers including repetitive sequencer and operable in any of a plurality of states, the one controller determines the critical time when each of the states should begin, and instructs each of the other controllers to begin any of the states at the associated determined critical time.
