Maintenance
(continued)
Applying/Buff i ng Roller Replacement
Replacing roller requires removal of shaft and
mounting screws. With no area on the shaft to grip,
the shaft often turns when attempting to remove the
second screw.
To ease removal of second screw, a 4mm hex
socket has been provided at the bottom of the
threads in both ends of the shaft. Insert a 4mm
hex key wrench into this socket after removing one
screw to hold the shaft for removal of the second
screw (
Figure 4-2).
Cleaning
Regular slotted containers produce a great deal
of dust and paper chips when conveyed through
taping heads. If this dust is allowed to build-up
on the heads, it can cause wear on the moving
parts. Excessive dirt build-up should be wiped
off with a damp cloth. Cleaning should be done
once per month, depending on the number and
type of boxes used. If the boxes used are dirty, or
if the environment in which the heads operate is
dusty, cleaning on a more frequent basis may be
necessary.
Note –
Never attempt to remove dirt from taping
heads by blowing it out with compressed
air. This can cause the dirt to be blown inside
the components onto sliding surfaces.
Dirt in these areas can cause serious
equipment damage. Never wash down or
subject taping heads to conditions causing
moisture condensation on components.
Serious equipment damage could result.
•
To reduce the risk associated with shear, pinch, and entanglement hazards:
−
Turn air and electrical supplies off on associated equipment before performing any
adjustments, maintenance, or servicing the taping heads
−
Never attempt to work on the taping head or load tape while the box drive system is running
•
To reduce the risk associated with sharp blade hazards:
−
Keep hands and fi ngers away from tape cutoff blades under orange blade guards.
The blades are extremely sharp
