7-INSTALLATION AND SET-UP (continued)
Pressure Regulator regulates main air pressure to the machine to adjust pressure,
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. The Exhaust Valve releases
exhaust air from the pneumatic circuit (but column air pressure is maintained).
Note: Column air pressure is maintained to keep the upper assembly from dropping too quickly from the
raised position.
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 turning switch on
side of machine frame to "ON" and then pressing the "Start" Station Button.
4. Raising Actuator, Upper Drive Assembly
This switch, when touched by the leading edge of a box, triggers a proximity sensor that pneumatically raises
the upper frame to allow insertion of the box under the drive belts. As the box moves under the switch, 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. Proximity Sensor, Box Centering Guide
This sensor controls the box centering guides. When sensor is activated by a box entering the case sealer,
the centering guides close (centering the box), and release (after box passes sensor), 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.
7. Air Pressure Regulator/Gauge, Upper Drive Assembly Force 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 positively conveying 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
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 necessary to get continuous movement of boxes through machine.
