Rejected Bottles Not Stable On The Takeaway Conveyor - Filtec OV-II Maintenance, Troubleshooting And Service Manual

Rejected Bottles Not Stable On the Takeaway Conveyor

SYMPTOM
Wrong Bottle
Rejected.
Reject blow-off
pressure too low.
Bottles released early
or other bottles are
rejected when normal
rejection occurs, i.e.,
'Drop off' bottles.
Damaged starwheel
suction cups - causing
reduced blow-off force
as well as less vacuum
holding force.
Bottles "hitting" reject
chain and falling over.

The rejected bottles may not be stable when they are released from the
starwheel, resulting in fallen bottles on the reject takeaway conveyor.
1. Check and correct any maintenance related problems as
discussed earlier in this chapter.
2. Re-calibrate take away motor in machine configuration motor
screen.
3. Look for possible causes and solutions as follows:
CHECK
Check the settings on the Bottle
Delay and in the CONTAINER
SETUP > TRIGGER AND
REJECT SETTINGS screen.
Check the air pressure regulator
inside the base cabinet.
Check vacuum gauge reading inside
the base cabinet. The pressure/
vacuum converter system, under
normal operation, must maintain 560
to 660 mm (22 to 26 inches) of Hg
while the starwheel is fully primed
with bottles.
Check suction cups for any damage,
i.e., grossly worn out and split cup
bellows or lips.
Check the positioning of the reject
conveyor chain in relation to the
bottle at the release (or blow-off)
point. Verify there is a clearance of 1
to 2 mm between the chain top and
bottom of bottle.
Chapter 2: Troubleshooting Procedures
SOLUTION
1. Adjust the settings as required.
2. For RF RLD and OSW stations,
the number of bottles between
each of these stations and the
BASE/ISW inspection
centerline should match the
respective numbers on the
screen. If not, adjust the
numbers accordingly.
Verify the pressure is set to between
276 and 414 kPa (40 and 60 PSI).
If the gauge reads less than 560 mm
(22 inches) of Hg, check other items
such as suction cups and piping for
leaks and refer to periodic
maintenance procedures as required.
Replace as necessary.
Readjust the reject conveyor chain
as required.
