P640i Card Printer User Guide

The flip station performs two independent functions: 
1. It lifts the card in process clear of the carriage, flips 
it upside down, then returns it to the carriage so that 
its other side may be printed; 2. It lifts the fully 
printed card clear of the carriage, raising it to the point 
where it lines up with the laminator’s infeed path. An 
ejector arm then propels the card into the laminator 
infeed rollers. 

Note that the flip action alternates in consecutive 
cycles between clockwise and counterclockwise. 

As the motor driven carrier rises, taking with it the flip 
arms and card, the cam is forced to rotate by the 
projection on the right side of the flip stop. The 
actuators do nothing at this time.

The cam 
is driven 
over 
center by 
the flip 
stop, at 
which 
point the 
flip 
spring 
takes 
over, 
fully 
inverting 
the card.  
Shown 
here at 
its upper limit of travel, the carrier is about to descend.

As the carrier descends, the cam deflects Actuator A, 
which in turn drives the flip stop to the right. Now, 
when the next flip is called for, the cam strikes the left 
projection of the flip stop, flipping the card in the 
opposite direction. Actuator B, moving in parallel 
with A, is then set to return the flip stop to the left 
when the carrier heads downward on completion of 
the flip action.

One end of the flip spring locates in a cavity in the 
rear flipper arm, the other in a hole in the rear 
surface of the carrier molding.
