2.5.3 Discharge Conveyor
The discharge conveyor is customer supplied and may be a gravity-fed or powered type. If the
discharge conveyor is powered, a smooth top surface is preferred. It is important to note that the
case discharge mechanism is designed to discharge the case against zero restraint. It is not
intended to overcome the friction of a long conveyor filled with cases, or push cases up an
inclined slope. Excessive discharge friction will cause improper machine operation.
2.6 Service Connections
2.6.1 Compressed Air
Connect the compressed air supply to the inlet end of the manual shutoff valve on the filter-
regulator unit mounted on the discharge end of the machine. The air supply should be clean and
dry, and the air-line should have a minimum inside diameter of 3/4” (for flexible tubes) or 1” (for
steel tubes). With the electrical power
OFF
, open the manual shutoff valve and check that the
regulator is set to a pressure of 90 PSI.
After connecting the electrical power (see Section 2.6.2), switch the electrical power
ON
; all
cylinders should revert to their
HOME
positions, and there should be no evidence of air leaks.
See Section 6.2:
‘Start-up’
. To check that the pneumatic components of each mechanism are
functioning properly, the solenoid valves may be operated mechanically.
CAUTION!
The machine should NOT be operated on casters.
SAFETY NOTICE!
Service connections (electrical and pneumatic) should
ONLY be undertaken by qualified personnel. Observe
proper lock-out procedures and recommended
sequence to avoid personal injury or damage to the
machine.
