3. Emergency Stop Switch
The machine electrical supply can be
turned off by pressing the latching
emergency stop switch (releases switch latch).
To restart machine, turn/release emergency
stop, press reset button and then press
"Start/Stop" Station Start Button.
4. Raising Switch - Upper Drive Assembly
This switch, when touched by leading edge
of a box, activates a switch that pneumatically
raises the upper frame to allow insertion of
the box under drive belts. As the box moves
under the switch, the upper drive assembly
descends on the box and drive belts convey
the box through the machine.
When switch is activated by hand, the upper
drive assembly rises to its maximum height.
Released, the upper drive assembly descends
to its rest position.
5. Photo Sensors/Ready Lights:
Ready Light (2) - indicates machine is clear/ready.
Box Present Sensor - indicates presence of
box initiating taping cycle.
Box Centering Sensor - This sensor controls the
box centering guides. Sensor is activated
when the box enters the case sealer and
centering guides close (centering the box).
Then, after box passes this sensor,
Centering Guides are released (Guides
return to original position ready for next box).
Blade Retract (Cut-Off ) Sensor - Upper/
Lower Heads) - senses when to retract/
engage or disengage Taping Heads cut-
off blade bracket (preventing box crushing).
Box Exit Sensor - indicates completion of
Box taping process.
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.
. 7. Air Pressure Regulator/Gauge,
Upper Drive Counter Balance
Adjustment – Figure 7-16
Set nominally to control "down"
movement of upper drive assembly
and resulting 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 which positively
conveys boxes through the machine.
This Pressure Regulator acts as a "counter
balance force" that equalizes air pressure on
the Column Cylinders and keeps the Upper
Drive 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 between the box and
drive belts). Adjust setting as needed to allow
ease of movement of boxes through machine.
