Abstract
A feed apparatus which combines a slider crank feed head drive system and cam actuated stack height sensing system to form a new combined shuttle feeder. The new feed head drive includes the replacement of a solenoid driven feed head with a more reliable stepper driven twin slider crank drive. Included in the slider crank drive for the feed head is an integral cam as part of the crank arm mounted to the motor shaft. This cam is designed drives a stack height sensor to drop and lift the stack height sensing arm to sense stack height after the sheet trail edge has passed the point of arm contact with the stack. The cam also provides a “service mode” position for the stack height arm which lifts it out of the way of the paper supply when it is opening. The cam dwells in a neutral home position during the rest of the drive out and return motion of the feed head.
