7. Installation
(continued)
Pressure Regulator regulates main
air pressure to the machine to adjust
pressure, pull knob up and turn –
push down to lock setting.
Filter removes dirt and moisture from
plant air before it enters the case
sealer pneumatic circuits. If water
collects in bottom of bowl, lift up on
the valve on the bottom of bowl to
drain. The Exhaust Valve releases
exhaust air from the pneumatic circuit
(but column air pressure is maintained).
Note: Column air pressure is main-

tained to keep the upper
assembly from dropping too
quickly from raised position.
The machine electrical supply
can be turned off by pressing
the latching emergency stop
switch. To restart machine,
rotate emergency stop switch
(releases switch latch) and then
restart machine by turning
switch on side of machine
frame to "ON" and then pressing
the "Start" Station Button.
This switch, when touched by
the leading edge of a box, triggers
a proximity sensor that pneumati-
cally raises the upper frame to
allow insertion of the box under
the drive belts. As the box moves
under the switch, the upper drive
assembly descends on the box
and the drive belts convey the
box through the machine.
When switch is actuated by hand,
the upper drive assembly rises to
its maximum height. Released,
the upper drive assembly
descends to its rest position.
Box Centering Guide
This sensor controls the box
centering guides. When sensor
is activated by box entering the
case sealer, centering guides
close (centering the box), and
release (after box passes sensor),
the guides open.

6. Air Pressure Regulator, Centering
Guide Force Adjustment – Figure 7-16
This regulator is used to adjust
Centering Guides according to
weight of boxes. Pressure should be
adequate to center boxes, but low
enough to allow easy pushing of
boxes under taping head.
7. Air Pressure Regulator/Gauge,
Upper Drive Assembly Force
Adjustment – Figure 7-17
Set nominally to control "down" move-
ment of upper drive assembly and result-
ing pressure exerted against the box.
The regulator setting is changed as
necessary for the boxes being sealed to
provide adequate drive belt pressure
against the box positively conveying
boxes through the machine. This Pres-
sure Regulator acts as a "counter balance
force" that equalizes air pressure on the
Column Cylinders and keeps the Upper
Assembly from dropping too quickly
from the raised position. If the boxes
stop or hesitate, decrease the Regulator
pressure (which will increase drive belt
force on the box) for more friction be-
tween the box and drive belts. Adjust
setting as necessary to get continuous
movement of boxes through machine.
