2.6.3 Feed Pusher Pneumatic Adjustment
Feed Pusher Pneumatic Adjustment
The feed pusher assembly moves the tray from a stationary position in the magazine onto the moving
conveyor (see figure Tray feed pusher assembly (view from top)). A pneumatic fl ow control valve deter-
mines the speed of the "push" function. The "pusher return to home" function is controlled by spring ten-
sion. The following procedure outlines the feed pusher adjustments.
The feed pusher pneumatic fl ow control is located under the bottom plate (see figure "Removing the Bot-
tom Plate").
► Remove the front cover and then bottom plate to access the fl ow control valve (see figure "Feed
pusher flow control valve").
► To adjust the feed pusher speed; unlock the adjustment screw by loosening the locking nut (see fig-
ure "Feed pusher flow control valve").
► To increase the feed pusher speed, turn the adjustment screw in a counter clockwise direction.
► To decrease the feed pusher speed, turn the adjustment screw in a clockwise direction.
► Adjust pusher speed so trays reliably move onto conveyor without dislodging components.
► When adjustment is completed, tighten the locking nut and reattach bottom plate.
