PILE FEEDER OPERATION
1.0 Loading the Pile Feeder
Set the right hand side guide (Figure 11-1) to half the
sheet using the scale (11-2). The vacuum wheel is in the
center of the sheet. Lock the guide in place using the lever
(11-3).
Remove the left hand guide (Figure 12-4) from the
feeder. Move the sheet drag guide block (12-5) on the right-
hand guide to the rear of the paper stock.
Press the table down button (for controls, see page 8). A
lower limit switch will halt the pile table when it descends
to the lowest position. Load the paper against the front and
right hand guides (11-1).
Press the table up button. The pile height sensor (11-6)
will stop the upward travel of the table. During operation,
the top sheet of the pile should be approximately 1/2" under
the vacuum wheel and 5/8" under the sensor (11-6), with
the pile up and the pump off. The pile height sensor is
contact-free.
Reinstall the left hand guide (12-4). Slide the register
guide (12-7) inward until the see-through left hand guide
(12-4) is approximately 1/16" away from the stack.
1.2 Hold-down Locations
Set the sheet hold-downs so the rubber bumpers rest on
top of the sheet pile and prevent double sheets from being
pulled in. Using the rubber bumpers is dependent upon the
stock being fed.
1.3Air and Vacuum Settings
Press the pile up button if it has not been pressed.
Press the pump "on" button.
Adjust the air flow into the top of the stack as shown in
Figure 13, using the blow tube angle levers (Figure 14-1)
and the air bleed off valve cover (14-2).
Figure 13 shows that the top four to five sheets are to be
separated using the top blow tube (13-1). The bottom blow
tube (13-2) separates approximately 1/2" of the stack under
the top four or five sheets. The bottom blow tube (13-2)
provides separation to send sheets up to the top to be fed.
Do not adjust the air angle flow too high into the
sheets. The top sheets should be in a humped pattern as seen
through the side guide for approximately 75% of the sheet
length.
