WF-10T Case Former Machine Maintenance

8.5.7 Mechanical Maintenance
•
Observe the machine in operation, looking particularly for any uneven or excessively
noisy motions and abnormal air leaks.
•
With the machine stopped and the air
OFF
, check for smooth action without excessive
bearing wear or abnormal looseness of all moving parts. See Section 8.5:
‘Maintenance
Adjustments’
for further details.
•
Inspect the machine for signs of abnormal wear, such as debris caused by scraping or
grinding together of parts. All piston rods on the air cylinders should be smooth and
shiny.
•
Watch for signs of improper belt tensioning, such as the belts slipping when transporting
a heavy case. Correct belt tension is one percent stretch from the no-load position - if in
doubt, slacken the belt to no-load, make marks on the belt
" 25
apart, and re-tension to
produce a distance of
" 25
4
1
between the marks. Always tighten tension bolts equally to
maintain correct tracking. See Section 8.5.3.
•
Carefully observe the conveyor side drivebelts and watch for signs of uneven wear (edge
fraying) which can occur if a belt is not tracking on-center of the pulleys. Adjust belt
tension and tracking as shown in Section 8.5.3:
‘Conveyor Belt Tension & Tracking’
.
•
Observe the motor that drives the drivebelts for signs of oil leakage; if serious leakage
occurs, replace the motor.
•
If everything appears to be operating normally, switch the machine
ON
and observe
carefully as it processes a case, listening for signs of air leakage or other abnormal
noises.
•
All mechanical actions should be smooth and free of shock at the end of the stroke.
8.6
Lubrication
The main components that require lubrication are:
•
Leadscrews
•
Chains and Sprockets
•
Sliding Components
•
Gear Reducers
8.6.1 Moving Components
All adjustment screws, chains and sprockets, and other sliding components, should be thoroughly
cleaned and lightly greased weekly. Use Food Safe Fuchs Geralyn FMG 387 lubricant or
equivalent.
8.6.2 Ball Bearings
All ball bearings used on Wexxar/BEL packaging machines are sealed-for-life, and regular
lubrication is not required.
8.6.3 Tape Head
The DEKKA WEX-22 Series Tape Heads are designed as a low maintenance item, and should
not require lubrication in normal use. The felt pad on the inside of the knife guard cover should
be lubricated with WD-40 or a similar low-toxicity lubricant every few days. This will prevent
adhesive build-up and lengthen the life of the cut-off knife.
