Operation (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.
3Emergency Stop Switch
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 pressing green (On) button
on side of machine frame.
4Raising Switch, Upper Drive Assembly
This switch, when touched by the leading edge
of a box , pneumatically raises the upper frame
to allow insertion of the box under the drive
belts. As the box moves under the switch,
releasing it, 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.
5Centering Switch, Box Centering Guide
This pneumatic switch controls the box
centering guides. When switch is activated by
a box entering the case sealer, the centering
guides close (centering the box), and released
(after box passes over switch), the guides
open.
6Air Pressure Regulator, Centering Guide
Force Adjustment – Figure 3-4
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. The regulator setting can be
locked by tightening the phillips screw as
shown.
7Air Pressure Regulator/Gauge, Top Drive
Assembly Force Adjustment – Figure 3-5
Set nominally to control "down" movement of
top drive assembly and the pressure exerted
against the box. The regulator setting is
changed as necessary for the boxes being
sealed to provide adequate drive belt pressure
Figure 3-5 – Air Regulator/Gauge, Top Drive
Assembly

against the box to positively convey the boxes
through the machine. If the boxes stop or
hesitate while being conveyed, decrease the
regulator pressure which will increase the drive
belt force on the box for more friction between
the box and drive belts. Adjust setting as
necessary to get continuous movement of
boxes through machine.
