8. Theory of Operation

Description of the Working Cycle
8.1 AIr Supply/Starting Machine/Operation
Air Supply:
The air supply powers movement of
centering guides and upper drive assembly
to automatically adjust the case sealer to
the size of box being sealed.
Be sure that the air valve is rotated to
"ON" position and main pressure gauge
is reading 85-90 psi (Figure 8-1).
Starting/Machine Operation:
- Check that E-Stop is released (Figure 8-2).
If E-Stop engaged, release E-Stop.
- Press Reset Button.
- Press Start Button (ready lights should
illuminate indicating machine is ready
for a box and lights turn off when box is
in taping process (Figure 8-3).
Note: In normal "Start/Stop"operations,
using reset button is not necessary.
Reset:
A reset is required for the following:
• Powering up machine.
• After E-Stop has been engaged.
• After a fault occurs (i.e. box jam,
taping issue, etc.).
Note: Ready Lights will automatically
illuminate when machine is ready for
next box.

8.2 Photo Sensors / Raising Switch

Box Centering Photo Sensor:
The Box Centering Photo Sensor is activated
as box is presented and forwarded on
infeed conveyor (Figure 8-4).
The box centering system is triggered
in the Programmable Logic Controller (PLC)
located in the Electrical Control Box
(Figure 8-4).
