Notes:
1. Machine or taping head adjustments
are described in
"Adjustments"
Section
for machine or
Manual 2 or
Manual 3
for taping heads.
2. Box drive motors are designed to
run at a moderate temperature
(See Specifications) In some cases,
they may feel hot to the touch.
7.17 Theory of Operation
The air supply powers movement
of the centering guides and upper
drive assembly to automatically
adjust the case sealer to the box
size being sealed as follows:
1. A box centering Proximity Sensor
in infeed roller conveyor actuates
movement of the centering guides.
When the operator pushes a box
onto the infeed conveyor, as shown
in
Figure 7-19,
the proximity sensor
activates causing the air cylinder
powered centering guides to move
inward, thereby centering the box.
2. Once the box is centered by the
guides, the operator pushes the
box against the Raising Actuator/
Proximity Sensor on the upper drive
assembly, as shown in
Figure 7-20
,
causing the upper taping head to
be raised by two air cylinders.
The upper taping head will continue
to rise above the box height so the
operator can insert the box under-
neath the upper drive belts.
3. Once the box is pushed under the
upper taping head, the upper drive
assembly raising switch is released
causing the upper drive assembly to
descend onto the box top, as shown
in
Figure 7-21
, allowing the drive
belts to convey the box through
the upper and lower taping heads
for application of the tape seals.
4. As the box is conveyed through the
machine, the box centering Proxi-
mity Sensor is deactivated causing
the centering guides to return to
their full open position, ready for
insertion of the next box.
At this point it is recommended that
the centering proximity sensor and
upper drive assembly switches be
manually actuated to understand the
functions described above. Activation
(run a box on conveyor) of the auto-
matic sensors causes the guides to
close, Deactivation (box moves past
Proximity Sensor) causes guides to
open. Depressing upper drive assem-
bly raising switch causes upper drive
assembly to rise, releasing the switch
causes drive assembly to descend.
