Mechanical Latch

A
For boxes which are fully packed with
products that support the top fl aps,
adjustment of this regulator is not
critical since the boxes can support
pressure of upper frame (drive belts)
at a wide range of regulator settings.
However, if under- fi lled or fragile
boxes are to be sealed, this regulator
can be used to set the upper frame to
a higher pressure that is adequate for
conveying boxes through the machine
while also allowing upper assembly to
descend on box (preventing box damage).
Note – A precision regulator is used
to balance upper drive assembly.
Due to the self relieving feature of
this regulator a small amount of air
will continually vent to atmosphere.
This is normal and amounts to
approx. 3 liter/min [0.1 SCFM ].
8 . Main Air Pressure Gauge -
Indicates main air regulator
pressure setting. Air regulator
should be adjusted so gauge reads
5 bar gauge pressure [70 PSIG].
9. Mechanical Latch, Upper Drive
Assembly ( Figure 7-18)
The mechanical latch is provided
to hold the upper drive assembly
at the fully raised position for tape
threading and maintenance.
To raise and latch upper assembly:
1. Push and hold upper frame raising
switch “A”.
2. Push and hold latching knob “B”.
3. Release switch “A”.
4. Release knob “B”.
5. Shut o ff air supply.
To release/lower the upper assembly:
1. Turn on air supply.
2. Push and release switch “A”.
10. Upper Drive Pressure Gauge
As indicated in Air Pressure Regulator /
Gauge, Upper Drive Assembly Force
Adjustment, Upper Drive Pressure Gauge
is used as indicator of “counter balance
force” that equalizes air pressure on the
Column Cylinders and keeps Upper As
sembly from dropping too quickly from
raised position. Adjust force higher (+)/
Lower (-) to equalize and create balance.
Important – Before turning drive belts on,
be sure no tools/objects are on the
conveyor bed.
11 . Electrical Control Box - Houses DC
Power Supply for Proximity Sensors,
Control Relays, Motor(s) Contactor,
and opening delay timer for Box
Centering Guides.
12. Push Button Station “Start/Stop”
Controls Box taping Cycle / Starts
and Stops Drive Belts.
7.16 Tape Loading/Threading -
See Manual 2 or 3.
Note – If lower tape drum is mounted in
alternate lower outboard position,
remove taping head from machine
bed by pulling straight up, insert
threading needle in taping head and
replace taping head. Install tape roll
on drum (adhesive on tape leg up),
thread tape under knurled roller on
outboard mount, then attach tape to
threading needle and pull tape through
taping head with threading needle.
• To reduce the risk associated with
pinch
hazards:
- Keep hands clear of the upper head
support assembly as boxes are
transported through the machine.
- Keep hands, hair, loose clothing, and jew-
elry away from box compression rollers.
- Always feed boxes into the machine by
pushing only from the end of the box.
