7-INSTALLATION AND SET-UP (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.
3. Emergency 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.
4. Raising 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.
5. Centering 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.
6. Air Pressure Regulator, Centering Guide
Force Adjustment – Figure 7-15
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.
7. Air Pressure Regulator/Gauge, Top Drive Assembly Force Adjustment – Figure 7-16
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 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.
